Dangers Of Sodium Lauryl Sulfate

Sodium lauryl sulfate (C12H25NaO4S, is called SLS for short) is a chemical compound used in personal care products, perfumes and cleaning detergents. The U.S. Food and Drug Administration listed it as a food additive and specified regulations and limits of its use. The chemical has been a controversial topic on the Internet as some health advocates purport its possible adverse effects on people.

Its role in these products is usually that of a foaming or a dispersal agent. For example, toothpaste or bubble baths that foam when used contain sodium lauryl sulfate, as well as products that need its components dispersed homogeneously, such as fragrance oils in body spray.

Clinical tests on rabbits demonstrated that 10 percent of sodium lauryl sulfate caused corneal impairment, especially if the chemical was not rinsed out of the eye, according to the Journal of American College of Toxicology. Rinsing reduces irritation to a degree, and if it’s not done promptly, then the damage is severe. Absorption and metabolism studies showed that SLS can destroy properties of proteins, causing deterioration in cell membranes.

According to the Journal of American College of Toxicology, human skin tests conducted showed that skin irritation was directly related to SLS concentration——the higher the concentration, the greater the irritation. It was concluded that the chemical’s contact with human skin should not exceed 1 percent. Additional tests conducted on rabbits found that SLS concentrations of .5 to 10 percent caused slight to moderate skin irritations, and concentrations of 10 to 30 percent caused severe aggravations.

Besides subjecting human and animal test subjects to different degrees of discomfort, critics claim that SLS is retained in the long run in organ tissues like the heart, liver, and brain. In lab animals, testing has been blamed for causing mutagenic effects. If they remain in the eyes for too long, they may also lead to the development of cataracts. Because sodium lauryl sulfate(CAS No. 151-21-3) is corrosive by nature, it can dry out skin by stripping the protective lipids from the surface of the skin, weakening the body’s natural moisture regulation mechanisms. If it eats away at the follicle, hair loss may also be induced.

It has arguably been called one of the most dangerous ingredients in products today. Household essentials like cosmetic cleansers, bath gels, shampoos, and dishwashing detergents contain up to fifteen percent sodium lauryl sulfate. In extreme cases, SLS is argued to be carcinogenic, though not by itself. When exposed to other nitrogen-bearing ingredients of a skin product though, the oxidation reaction that results may form nitrosomines, which are carcinogenic nitrates.

Common Types Of Hair Dyes

Hair dye has become an almost indispensable product for many different men and women. Many ladies and girls have their hair dyed on a regular basis through a salon or at home. However, apparently women don’t like their hair because more women are changing the color of their hair than ever before. But is this obsession with finding the perfect color bad for our hair? The answer is: It depends.

Permanent Dyes
A permanent dye is the longest lasting type of dye. However, these dyes are also the harshest on your hair. The dye uses ammonia and hydrogen peroxide to expand the hair molecules so that they are too big to be washed out. These dyes last until the new hair roots grow in. When you use it, it creates a new color base for your hair, and then re-dyes it to the new color. For this reason, the same base color looks different on other people.

Semi-permanent Dyes
Semi-permanent dyes are the kind that most people use when they visit the hair salon. They are a little less harsh than the permanent dyes, but they last longer than the temporary dyes. These dyes contain ammonia or hydrogen peroxide, and it is possible to get a lighter shade with these dyes. When the dye is placed in the hair, the dye penetrates the hair shaft, and then bonds with the hair molecules already there. This dye usually lasts for about a month.

Temporary Dyes
A temporary die is usually sprayed on, or it can be applied in a gel or mousse. When the hair gets wet, the dye runs out of the hair. This can be very messy. The reason that this happens is that there is no bonding of molecules with this kind of dye.

Common Ingredients
Ammonia and hydrogen peroxide are the main components that keep the hair dye bonded to the hair. They are able to seep inside the hair follicles, taking the dye with them. That is how the dye stays on the hair for longer periods of time. However, there has been some research to suggest that certain chemicals in hair dye can lead to certain cancers.1-Fluoro-4-nitrobenzene (also known as 4-Fluoronitrobenzene or p-fluoronitrobenzene, the CAS number is 350-46-9) is also used in hair dyes.

Long-Term Damage
The FDA has backed off of approving coal tar dyes; if the box has the patch test instructions, that’s all it needs. The problem with continued use however, is that someone can develop an allergy later on in life. Another problem to the hair emerges when women have their hair straightened and colored, too. Also, overuse of dyes, dye sitting too long to develop, and other variables can damage hair. This will typically mean breaks in the shaft of the hair.

Fluorosilicic Acid Information

Fluorosilicic acid, also called hydrofluorosilicate, is an industrial byproduct with applications in public health, hygiene and arts and crafts. It comes from phosphorite rock used in the manufacturing of phosphate fertilizer.

Fluorosilicic acid preserves fiber strength and sets acid dyes to prevent fabric discoloration. Businesses including hotels and hospitals use fluorosilicic acid as a laundry sour, a cleaning agent added during rinsing to break down residual bleach and remove sodium bicarbonate, a chemical compound that can damage fabrics during ironing or pressing. The acid also dissolves iron and other metallic salts that cause rust stains, graying or yellow discoloration. Laundry sours containing fluorosilicic acid aren’t available for home laundries.

Tanners use fluorosilicic acid to cure and preserve animal hides and skins. It also makes fluorosilicate or fluoride salts which are used to make industrial compounds and metals and to help cool nuclear reactors. The compound is added to cement and applied to wood to preserve both materials, and it’s used in the manufacture of ceramics, glass and paints. Brewing and bottling plants use fluorosilicic acid to sterilize factory equipment. It’s also used in electroplating and glass etching, and to refine lead and acidize oil wells.

Fluorosilicic acid has been the main additive for water fluoridation in the United States since the 1950s. Combined with a related compound called hexafluorosilicate, the acid makes up fluoride mouth rinses. As of 2001, municipalities across the nation added silicofluorides to more than 9,200 water treatment systems serving more than 120 million Americans, according to the Centers for Disease Control and Prevention. Fluoride makers change fluorosilicic acid from its water-based solution into powdered derivatives called sodium fluorosilicate(F6Na2Si, CAS No. 16893-85-9) and sodium fluoride, which suppliers add to drinking water.

However, the acid’s role in water fluoridation is controversial. Scientists at Dartmouth College found in 2001 that children exposed to drinking water containing the acid have higher levels of lead in their blood. Recent studies from the U.S. Environmental Protection Agency found that too much of the additive can cause brittle bones as well. Exposure to high levels of fluorosilicic acid vapor or mist in factories can burn the eyes and cause coughing, chest pain and breathing difficulties. But the U.S. Department of Health and Human Services says the amount of fluorosilicic acid in drinking water is too minimal to cause health problems.

What Can Calcium Acetate Be Used For?

Calcium acetate, made up of calcium, carbon, hydrogen and oxygen, is the calcium salt of acetic acid. It has the formula Ca(C2H3OO)2. Other names such as acetate of lime, calcium ethanoate and calcium diacetate are also known by people. In appearance, the chemical is a white granular powder that does not have any smell. It is used in both the food and pharmaceutical industries in medication and as a food additive that acts as a stabilizer.

Calcium acetate is created by making a calcium salt from acetic acid. The most prolific use of this compound in the food industry is as a stabilizer. Stabilizers perform several functions in manufactured foods, mostly in powdered foods but also in liquid and solid foods. They are able to organize flavoring compounds and give the product a uniform texture. With foods that use an emulsifier to bind ingredients, calcium acetate further binds the ingredients to ensure nothing separates.

Many dairy products, such as drinks, condensed milk, milk powder and cream, use calcium acetate. Cereals and batters, along with edible casings for sausages and many types of pasta need this substance for proper production and storage. It also extends the shelf life for all food in which it is used.

As a medicine, this substance is used to ensure phosphate levels in the blood do not become dangerously high for dialysis patients with kidney disease. When phosphate builds up in the blood it can combine with calcium in the blood and this mixture can cause damage by being deposited on the blood vessel walls. It can also cause itchiness and affect the strength of the bones and joints. Calcium acetate(CAS No. 62-54-4) tablets prevent the absorption of phosphates into the bloodstream as they bind to the phosphate in your food. The combination is then passed out in your stools.

According to the U.S. Food and Drug Administration (FDA), this substance is considered to be generally safe on several levels. As a substance by itself, it is considered safe. Most FDA regulations regard calcium acetate’s use in food. As a food coating, ingredient and direct food substance, it is considered to be safe.

Sorbitol — A Sugar Substitute

Sorbitol(C6H1406), sometimes also called as D-glucitol or D-Sorbitol, is a slow-metabolizing sugar alcohol that has 1/3 fewer calories than sugar derived from fruits, corn and seaweed. It has several cosmetic and medical applications and is added to oral health products.

This sweetener is actually a sugar alcohol that is also known as glucitol. It is a white powder or liquid that is sweet in taste and odorless. Unlike other sugar alternatives, however, it has only about 60% of the sweetness of sugar, but it is 10 times sweeter than xylitol. It is very slow to metabolize in the body, which lessens the chance of increased levels of insulin. This makes sorbitol a good sweetener for diabetics.

Since it’s very slow to be metabolized by the body, sorbitol does not cause insulin levels to increase as much as sugar. The product also doesn’t lead to tooth decay and is used in many sugar-free cough syrups. It is a popular addition to gel toothpastes as it helps add transparency.

Sorbitol is one of the most familiar sugar substitutes and is a frequent addition to diet foods. Low calorie candies, ice cream, baked goods, and chewing gum are commonly made with this sweetener. Foods made with this ingredient stay fresh and moist longer than those made with most other nutritive sweeteners. A small amount added to peanut butter improves spreadability and keeps it from becoming dry and crumbly. It is also added to shredded coconut to keep the flakes moist.

Sorbitol is added to soaps, especially transparent glycerin bar soaps. It has moisturizing qualities and may be found in lotions and moisturizing soaps. Therefore, the alcohol has been used in cosmetic products for close to a century and is a Generally Recognized as Safe (GRAS) product by the United States Food and Drug Administration (FDA).  Mouthwashes and toothpastes are made more transparent and pleasant tasting with the addition of this sugar alcohol, as are cough drops and syrups. Hair gels and shampoos also frequently contain it.

Laxatives are sometimes made with this alcohol, usually in liquid or enema form. When used in this form, the bowel is stimulated as it retains water within the colon and increases muscle movement. It is also used as an irrigation solution during urinary and prostrate surgeries to prevent infection and is administered by injection. D-glucitol can be combined with Kayexalate to eliminate excess potassium from the body when medically necessary. Most people, including the elderly, can usually use these products safely.

Though safe in small to moderate amounts, the substance does have some harmful side effects when too much is consumed. They include dry mouth, excessive thirst, dehydration, and edema. When larger amounts are ingested, it can cause abdominal cramps, diarrhea, and bloating.

L-ascorbic Acid In Broccoli

Most people are familiar with L-ascorbic acid(C6H8O6), more commonly referred to as ascorbic acid or vitamin C. Vitamin C is known for its antioxidant properties. It is a molecular bond of carbon, hydrogen, and oxygen. Humans are unable to synthesis vitamin C; therefore, it must be attained from supplements or a balanced diet.

The concept of the vitamin, a nutrient essential for health, was not established until 1912. Vitamin C was first isolated by Hungarian and American researchers in 1932. A few years after this discovery, vitamin C was the first vitamin to be synthesized in a lab. By 1934, vitamin C was the first mass-produced vitamin supplement.

As vitamin C, ascorbic acid was once invaluable in preventing diseases like scurvy, caused by lengthy ship voyages. To combat scurvy, sailors and passengers were often given oranges, which are high in ascorbic acid. While most animals synthesize ascorbic acid naturally, humans and primates do not. It is essential to the body’s processes, and all humans must consume it through either food or supplementation. Vitamin C helps to produce collagen. It is also vital in the production of dopamine and adrenaline, and necessary to the function of almost all major organs.

L-ascorbic acid is required for the production of the protein collagen, which is found in the tendons, skin, bones, cartilage, ligaments and blood vessels. Collagen and vitamin C are necessary to support the body tissues, heal wounds and help maintain blood vessel structure. Vitamin C also functions as a cofactor assisting biochemical reactions, as an antioxidant preventing the degradation of substances in the body, and as a detoxifier reducing the toxicity of medications and chemicals.

Food Resources
Fresh fruits and vegetables are the best source of natural L-ascorbic acid – particularly citrus fruits and vegetables such as broccoli and parsley. Vitamin C is available from animal sources, but cooking destroys the nutrient. Vitamin C supplements are one of the most common dietary supplements and are readily available in most countries. Since most cooking methods deplete the content of vitamin C, one of the best methods for adding it to one’s diet is to eat citrus fruits raw, or to very lightly cook green vegetables like broccoli.

Camphor Spirit Information

Camphor spirit is otherwise known as gum camphor, laurel camphor or simply camphor.  It is available as camphora and synthetic tablets and has a long tradition of use, both topically and via steam or direct inhalation.

Camphor is a substance derived from the camphor tree, Cinnamomum camphora. It can also be produced synthetically. It is a white crystalline substance and has a strong, distinctive, penetrating odor. The spirit portion of camphor spirit refers to some sort of alcohol, often a pure ethyl alcohol. An herbal spirit, such as camphor spirit, is often called a “tincture.”

Skin Problems
Spirit of camphor may be used as a rubefacient, which is applied to the skin for the purpose of relieving pain. It may relieve muscular pain when mixed with an alcohol solution and applied to the skin. Spirit of camphor may be applied to the skin and used as an analgesic or a counter-irritant when used in liniments. It works as a counter-irritant in neuralgia and fibrosis. It may also work as a counter-irritant for similar conditions. Camphor may be used in dermatology in the form of a lotion to work as a skin anesthetic and an anti-pruritic.

Topical Pain Relief
Camphor has been used to relieve pain via topical application. To use a camphor spirit as pain relief, for sore muscles or a sore throat, a bandage could be soaked in camphor spirit and applied to the sore area. Camphor spirit should never be used on broken skin or open wounds.

Steam Inhalant
Camphor spirit can be used to relieve and reduce coughing from cold, sinus infection or allergic irritation. Use of a camphor substance in a steam vaporizer can help relieve coughing by working with the steam to moisten breathing passages, thus calming the cough reflex.

Spirit of camphor is useful to dentists when their patients require a procedure, such as on a root canal. When the root canal becomes infected, the antibacterial used by the dentist may contain camphor. It is mixed with parachlorophenol( C6H5ClO,better known as P-Chlorophenol or 4-Chlorophenol), with camphor making up 65 percent of the substance and parachlorophenol making up 35 percent of the substance. It may also be used in dentistry to treat periapical infections.

Internal use of camphor is highly discouraged due to the possibility poisoning. It can also be harmful to young children if it is used as a nose ointment for infants. Spirit of camphor may be dangerous as a vapor and flammable if it comes in contact with a high amount of heat.

Chemicals Used In Nail Polish

There’s nothing like a pair of well-manicured hands. Therefore women even men pamper themselves with nail polish to signify class, glamor and maybe a little bit of wealth. Unfortunately, nail polish causes more than admiring glances because of the ingredients in it. Different brands of fingernail polish can include different ingredients. Regular commercial polish is full of dangerous chemicals that pose serious health threats to humans.

Toluene is a chemical used in nail polish. It is a clear and colorless liquid used to make dyes and paints. Toluene is also used for paint thinners and explosives. This dangerous chemical has been known to affect the function of the central nervous system, according to greenlivingtips.com. Exposure to toluene can cause headaches, fatigue and dizziness. This chemical in nail polish has also been linked to kidney and liver failure.

Ethyl Acetate
Ethyl acetate evaporates from the nail, which causes the polish to dry and harden. This means that you’re breathing in the fumes from the chemical as your manicure sets. This solvent can pass through the skin, and prolonged exposure to the fumes can lead to lung, heart, kidney, and liver damage.

One of the ingredients in nail polish is formaldehyde. This chemical is used for its preservative qualities. However, formaldehyde can cause dangerous health effects. Exposure to the chemical can cause wheezing, coughing and irritation to the throat, according to greenlivingtips.com. Formaldehyde is also harmful when it comes into direct contact with skin. Skin irritation and rashes occur from exposure to this chemical.

Phthalic Anhydride

Phthalic anhydride
(CAS number: 85-44-9) is the organic compound with the formula C6H4(CO)2O. It is the anhydride of phthalic acid. This colourless solid is an important industrial chemical While used in nail polish, the chemical becomes a major health concern because it may be toxic to human immune and respiratory systems, and can cause cancer, organ damage, and membrane irritation.

Dibutyl Phthalate
Phthalates are easily absorbed chemicals that keep nail polish chip-free. The European Union has banned them, but they’re legal in the United States. They’re linked to early puberty in girls, low sperm count in men, sexual deformities and problems with fetal development.

Budesonide Treatment Of Crohn’s Disease

Budesonide(or S-budesonide) is a prescription medication used to treat manage Crohn’s disease, an inflammatory condition of the digestive tract that causes severe abdominal pain and bloody diarrhea. It is classified as a glucocorticoid, a class of steroids that reduce the immune system’s natural inflammatory responses. It is also used as a maintenance therapy for asthma. By following doctors’ instructions and attending regular checkups, most people respond well to the medication and experience significant symptom relief after just a few doses.

Glucocorticoids such as budesonide are synthetic hormones that seek out and bind to receptor sites on body cells. The immune system responds to their presence by stopping the release of inflammation-inducing chemicals. Without triggers from the immune system, inflamed muscle tissue and mucous membranes gradually begin to relax, expand, and heal. Normal functioning is restored once pain and swelling are fully relieved.

For Crohn’s Disease
At the beginning of therapy with budesonide for Crohn’s Disease, the recommended dose is 9 mg each day. The capsules are available as 3 mg each. Take 3 capsules daily, usually in the morning. Treatment at this dose will continue for up to 8 weeks at which time your doctor will discuss your symptoms with you. If they are still troublesome, another 8 weeks of treatment is suggested. Once the symptoms are under control, a maintenance dose of 6 mg daily may be ordered and the goal is to keep your digestive tract calm. If there is a flare-up, the initial sequence may be repeated.

For Asthma
Budesonide treatment for management of asthma is by inhalation using an inhaler which contains powdered medication or with liquid turned into a mist using a nebulizer. It is important to use this medication at regular intervals. If the medicine is ordered twice daily, take it as close to 12 hours apart as possible. For example, at 8 in the morning and 8 at night. If ordered once daily, take it at the same time each day. Following nebulizer treatment, wash your face to prevent skin irritation. Store unopened vials of s-budesonide in the foil package it comes in and discard any opened vials.

The most common s-budesonide(CAS number:51333-22-3) side effects are headache, dizziness, nausea, and fatigue. Some people have indigestion, stomach cramps, and gas after taking a dose. Nasal sprays and inhaled solutions may cause runny noses, sneezing, and coughing. Rarely, the drug can induce a serious allergic reaction that may cause skin hives, airway constriction, chest pains, and breathing difficulties. All side effects should be reported to the prescribing doctor, and severe reactions should be assessed and treated at the emergency room to prevent potentially serious complications.

Information On L-Cysteine Hydrochloride

It can be difficult to determine if some types of additives are derived from animals or not. This is because it all depends on how the additive has been manufactured in the first place. However, the use of E Numbers on ingredients lists has become unfashionable, particularly in the UK. This is because the representation of E Numbers tend to be associated with the negative health affects on the consumer. L-Cysteine hydrochloride is showed on the lists, here, let’s talk about this chemical.

L-Cysteine hydrochloride(C3H8ClNO2S) is a nonessential amino acid in human development. It is freely soluble in water, alcohol, acetic acid, and ammonia water, but is insoluble in ether, acetone, ethyl acetate, benzene, carbon disulfide, and carbon tetrachloride. In neutral or slightly alkaline aqueous solutions, it is oxidized to cystine by air. It is more stable in acidic solutions. American Regent had temporarily suspended manufacture of most drug products including L-cysteine hydrochloride injection in April, 2011.

Calculate the quantity of each ingredient for the amount to be prepared. Accurately weigh or measure each ingredient. Mix the cysteine in about 40 mL of Sterile Water for Injection. Add sufficient hydrochloric acid 2N solution to a pH of 1 to 2.5 to form a clear solution. Add sufficient Sterile Water for Injection to final volume; mix well. Filter into sterile containers. Package and label. This formulation should be prepared according to strict aseptic compounding technique in a laminar airflow hood in a cleanroom or via isolation barrier technology by a compounding pharmacist who is validated in aseptic compounding. This is a high-risk preparation.

Hydrochloric acid (HCl) occurs as a clear, colorless, fuming aqueous solution of hydrogen chloride that has a pungent odor. Concentrated hydrochloric acid is 36.5% to 38.0% w/w concentration. It has a specific gravity of 1.18 g/cm3, is miscible with water, and is soluble in ethanol. The pH of a 10% v/v aqueous solution is 0.1. Hydrochloric acid should be stored in well-closed glass or other inert containers.

L-Cysteine hydrochloride anhydrous(CAS number is 52-89-1) solution is intended for use only after dilution as an additive to crystalline amino acid injections to meet the nutritional amino acid requirements of infants receiving total parenteral nutrition (TPN).

Premature or sick infants may receive TPN before starting other feedings or when they cannot absorb nutrients through the gastrointestinal tract for a significant period of time. TPN confers a level of nutrition that is superior to standard IV feedings, which provide simply sugars and salts. L-Cysteine hydrochloride 50 mg/mL injection is used for TPN in infants.

Breathalyzer Used For Testing Alcohol

Invented as breath-analyzing products by Smith and Wesson in the late 1950s, but now, breathalyzers are instruments that are utilized in a number of professions to determine the amount of blood alcohol content by analyzing a breath sample obtained from an individual. Literally dozens of breathalyzer models exist, most hand-held. Because of their frequent use as evidence in criminal courts, their design and performance is subject to highly prescribed regulations.

Alcohol is not digested in the body; it is simply absorbed into the tissues of the mouth, throat, stomach and intestines and eventually excreted. In part, alcohol leaves the body via the breath; because the percent of the total blood alcohol that exists this way is predictable, the alcohol content of the breath can be used to calculate the total blood alcohol content, or BAC.

While the principles behind breathalyzers are sound, they can only more or less estimate BAC since they do not measure it directly. An artificially high or low reading can result due to several different factors, all of which are frequently exploited by defense lawyers. For starters, body temperature and blood composition can alter the partition ratio — individuals with reduced blood content will show an artificially high BAC reading.

The breathalyzer works on the principle of estimating the blood alcohol content of an individual based on a sample of breath that is obtained from the suspect. When a police officer pulls over a driver on the suspicion that the individual may be intoxicated, it is not uncommon for the officer to ask the driver to take what is known as a field sobriety test. Essentially, this involves using a hand held breathalyzer.

The hand-held breathalyzer uses electrochemical fuel cell technology to identify the elements found in the sample, of course, searching specifically for alcohol. Some devices use an infrared spectrophotometer to scan the sample, identify alcohol and calculate its percentage content. The BAC is then figured based on a partition ratio, the ratio of breath alcohol to blood alcohol, of anywhere between 1700 and 2400. The output of the breathalyzer is a blood alcohol reading expressed as a percentage of the blood that is alcohol.

Potassium dichromate(K2Cr2O7, also called as potassium bichromate) is the active ingredient in a breathalyzer. Alcohol exhaled into the breathalyzer initiates a chemical reaction that indicates the amount of alcohol in the breath, therefore in the blood. Alcohol in the breath turns the red-orange potassium dichromate in the breathalyzer yellow, blue or green, depending on the amount of alcohol. The potassium dichromate breathalyzer test is as accurate as blood and urine tests in determining blood alcohol content

Most breathalyzers also cannot differentiate between ethyl alcohol and chemically similarly compounds such as ketones, acetone and gasoline, so the presence of these substances in the testing environment or in the subject’s metabolic system will also produce a falsely high reading.

Greenhouse Advantages

Greenhouses are structures that collect solar energy, usually to provide a climate-controlled environment in which plants can be grown. It allows growers several advantages over those who grow their plants outdoors in the natural environment and weather. Greenhouses have some advantages over traditional outdoor growing that make them popular for those who place a great deal of importance on the success and quality of their plants.

Multiple Crops
Plants are seasonal in most cases. Those that produce fruits, vegetables or flowers typically do so only during certain times of the year.The timing varies depending on the climate where the plants grow. In warmer weather climates, for example, flowers can continue to bloom for several months longer than they would in a place with short summers.

Heat and Ventilation
Because different materials absorb and release heat energy at different rates, the materials placed inside a greenhouse will determine how quickly the heat that enters through the glazing will remain inside the greenhouse. Concrete, rocks and water all retain heat for long periods of time and can be used to keep a greenhouse warm overnight.

High Quality Produce
Control over the conditions inside a greenhouse allows the grower to set up an environment that is ideal for the particular species being grown. With ideal weather, produce tends to grow healthier and larger than it would in unpredictable conditions. At the very least, the results are fairly predictable. Growers who know what conditions make for the very best produce can set up their greenhouses to allow for the highest quality plants possible.

Air And Sunshine
In some cases, additional technologies may be needed to keep the desired conditions inside a greenhouse. Horticulture lamps can be employed when there is not enough sunlight. When heat retention is the issue, materials that store heat through a phase change can be used. Chemical compounds such as sodium thiosulfate pentahydrate(Na2S2O3?5H2O, CAS No. 10102-17-7) and calcium chloride hexahydrate can be placed inside the greenhouse where they will melt during the day, absorbing heat from the sun. At night, these materials will turn back into solids and release their stored heat into the air inside the greenhouse.

The materials available for greenhouse construction have continued to evolve over time. New materials and manufacturing methods allow for several types of glazing to be used, both for letting sunlight enter the greenhouse and to retain the appropriate amount of heat inside. Because plants grow more evenly under diffused sunlight, glazing that breaks up the spectrum of sunlight while allowing the full range of radiation to pass through is ideal. This includes glass with a rough surface, fiberglass panels and double-layered plastic glazing (polyethylene).

A Treatment Of Systemic Herpes

Acycloguanosine is an anti-herpes drug that is frequently prescribed to combat various strains of the herpes virus, most notably herpes simplex virus type 1. Since the raw crystalline powder has the lengthy chemical name of 2-amino-1,9-dihydro-9-[(2-hydroxyethoxy)methyl]-6H-purin-6-one, it is most commonly referred to in clinical settings as acycloguanosine. However, it is marketed as a pharmaceutical under the trade names Cyclovir,Acyclovir, Acivir, Zovirax, and Herpex, with the medication being recognized as the standard International Non-proprietary Name for this drug.

Forms and Dosage
The drug comes in tablet, capsule, or liquid form, which may contain 200, 400, or 800mg of active ingredient. It is formulated into topical creams for the treatment of herpes simplex outbreaks affecting the mouth or genitals. In addition, the drug is available as an ophthalmic ointment or drops on a three percent concentration to treat keratitis of the cornea. It may also be given by injection in 25mg/mL concentration to immunosupressed patients that are infected with varicella-zoster, the virus that causes chicken pox in children and shingles in adults.

As being highly selective toward thymidine kinase, an enzyme “programmed” by herpes simplex and varicella-zoster, this drug has the ability to inhibit viral replication. This promotes a chain of enzymatic reactions and phosphorylation to bring about the conversion of Acyclovir to acyclovir monophosphate and ultimately to acyclovir triphosphate. The antiviral actvity triggered by these events can be observed both in vitro and in vivo, which means outside as well as inside the body, respectively. In addition, acycloguanosine is a prodrug, meaning that it becomes active when introduced into the body in an inactive form and subsequently metabolized. This is fortunate since the drug is otherwise poorly absorbed.

For Herpes
Herpes is a very common viral infection, and a majority of humans in most populations will have been exposed to at least one strain of this virus by the time they reach late middle-age. A herpes infection typically produces painful lesions that ooze for a short period and then scab over and begin to heal. The infection remains dormant in the body after this and may break out to produce lesions again at a later date.

No drug can cure herpes, or any other viral infection, but antiviral medications such as acycloguanosine(CAS No. 59277-89-3) can help the body to gain the upper hand in the struggle against a viral infection. The use of acyclovir for herpes treatment is part of standard medical practice in most regions because this drug is typically highly effective. This drug is most effective when administered intravenously but is still generally potent when given orally. Almost all strains of the herpes simplex virus respond well to treatment with this medicine, although limited resistance does occasionally emerge.

Significance Of Manganese In Industry And Body

The chemical element of manganese is designated with a chemical symbol of Mn and has an atomic number of 25. Here are some basic facts about this chemical, its uses and examples of how the element is a vital component in everything from steel production to the health of the human body.

For Health
In human body, the use of manganese as an essential trace mineral that is considered to be both a brain and a nerve food. The mineral is considered to be essential for the formation of healthy red blood cells, proper pituitary gland function, and the maintenance of good eyesight. Many herbal supplements that are meant to combat mental and physical fatigue, digestion problems, and nervous conditions will contain herbs such as ginger and catnip, both known to contain significant amounts of the mineral. It is safe to say that Mn is an essential part of our lives in more ways than one.

One of the more noticeable manganese deficiency symptoms has to do with the proper healing of wounds such as cuts and scratches. Since the mineral aids in the creation of collagen, the deficiency will make it more difficult for the natural healing process to take place. Women may experience problems with the menstrual cycle as a result of a deficien0cy. The cycle may become erratic in both timing and the severity of the cycle itself.

The most significant of all the industrial uses of manganese is steel production which uses more than 85% of all this mined. It can be used in several different alloying processes to improve the durability of steel. The ore is particularly useful in increasing steel’s resistance to oxidation, so the mineral is often used to make stainless steel. The addition of it to steel can also improve the overall strength and workability of the material. Hadfield Steel is one example of a mixture of steel and Mn, and is known for both these properties.

A number of other uses are common today. Fore example, the inclusion of manganese(CAS:7439-96-5) in gasoline additives has been shown to boost octane ratings and helps to minimize engine knocking. In glass making, it helps to remove the green tinge that is something left by the presence of iron particles. Its phosphates help to deal with rust and corrosion on steel surfaces. Its oxide has a brown appearance that can be used in paints.

The element is also used sparingly in the manufacture of coins in various countries. Current, the European Union uses manganese to produce one- and two- Euro coins, while in the United States, the one dollar coin contains high levels of Mn.

The Effects Of Paper Manufacturing On Human

Around 1440 the first printing press was invented by Johannes Gutenberg, an invention that would change the world. Mechanized, mass production printing would become increasingly sophisticated and efficient. But now, it is hard to imagine something as commonplace and necessary as paper as representing a devastating environmental and health hazard.

Global Warming
Carbon dioxide is a byproduct of paper production. Carbon dioxide is also a greenhouse gas which contributes to global warming. According to the IPCC (Intergovernmental Panel on Climate Change), global warming is “very likely” caused largely by humans. They report a 90 percent likelihood. If this is true, there is no doubt that the mass production of paper is a contributor.

Dioxin persists in the environment and can build up in bodily tissues, leading to cancer and liver dysfunction. Methanol may be released in the log-pulping process, and the substance is highly toxic to humans. High enough doses result in central nervous system damage and blindness, and long-term exposure causes liver damage. Evaporated methanol reacts in the air to form formaldehyde, a probable carcinogen, which also causes headaches and irritation of the eyes and throat.

Acid Rain
The manufacturing of paper produces nitrogen dioxide and sulfur dioxide. Nitrogen dioxide and sulfur dioxide are primary agents in acid rain. Acid rain has been responsible for increasing the acidic levels of lakes and subsequently rivers. These rising acidic levels have negatively impacted the fish and associated wildlife populations due to toxic levels of acidity.

Sulfur Compounds
Volatile sulfur-based compounds are used at multiple stages in the paper manufacturing process, and while most of the sulfur is generally recovered, some is released as sulfur dioxide, a compound that contributes to acid rain. Other volatile sulfur compounds, such as hydrogen sulfide, dimethyl sulfide and methyl disulfide(C2H6S2, better known as dimethyl disulphide), pollute the air and give paper plants their characteristic “rotten egg” smell, making nearby areas unpleasant to live and work in.

Paper bleached with hydrogen peroxide results in chlorine-free paper and a reduction of dioxins, thereby reducing the incidence of cancer and liver problems in surrounding areas. Recycling reduces the demand for virgin wood and thus reduces the need for toxic chemicals associated with pulping. New technologies are allowing for safer methods of pulping and for the production of nontoxic vegetable inks, reducing the risk of sickness from exposure to chemical toxins.

Ingredients Used In Common Fragrance

Fragrance can range from a simple concoction to a complicated mix of chemicals and additives, from natural substances to organic substances, as well as synthetic chemicals used to give a scent to products, such as shampoo, soap, cosmetics, and perfume. The best part of learning about perfume is that you can make your own easily and without spending a lot of money.

Fragrance has been used for thousands of years since it was first discovered. The ancient Egyptians buried pots of it with their mummies. The ancient Greeks also used perfume. In Marie Antoinette’s time, 18th century men and women would wear it to cover their body odor, since they did not bathe as often as we do in today’s society. Victorians had simple versions of perfume as well. Throughout the years, its basic function has stayed the same—to make you smell good.

Almost all charming men like natural scents like water or pine and can share a woman’s taste for musky scents as well. On the contrary, women’s perfume often smells flowery, like roses or honeysuckle. Some women may prefer powdery scents, such as the light scent of baby powder. Still other women may like musky scents, such as amber or myrrh.

A major ingredient of most perfumes in alcoho. Natural ingredients used in fragrance include essential oils extracted from plants and flowers, and animal products such as musk from male deer, ambergris from sperm whales and castor from beavers. In addition to the oils and animal products, perfume may have a number of synthetic compounds. These allow commercial fragrances to be cheaply mass-produced, but they are also often the source of allergies and skin irritations.

Ethyl acetate and 1′-Acetonaphthone(C12H10O, CAS No. 941-98-0), which are commonly found in colognes, shaving products, and nail-care products, may cause skin and eye irritation, as well as dizziness in certain individuals. Limonene, which is a common ingredient found in perfumes and soaps, is thought to be carcinogenic with prolonged use or skin contact.

You can simply pick a favorite bunch of flowers, crush them to release their natural oils, then mix them with a bottle of plain lotion. The lotion then must sit for a week or so until the oils have been absorbed. The wearer can then remove the flowers from the lotion, or leave them in for effect. This can be done with any flower or plant.

Piroxicam Used On Dogs To Treat Bladder Cancer

Piroxicam(also known as Baxo or Erazon) is a non-steroidal anti-inflammatory drug used to ease the pain and swelling caused by arthritis.  It works by reducing the amount of prostaglandins in the body, which is the substance that causes some types of painful swelling and fever. While many people experience few or no side effects, there is a potential for minor or serious side effects, and there are some precautions that must be taken while using the drug.

Nonsteroidal anti-inflammatory drugs(NSAIDs) like piroxicam, referred to as “cox inhibitors” because they block the actions of the cyclooxygenase enzymes COX-1 and COX-2, are used to reduce TCC-related bladder inflammation caused by the prostaglandins that COX-2 produces in the presence of inflammation. Although the connection is not entirely understood, veterinarians are finding that this medication may increase tumor cell death and negatively impact the development of the tumor’s supportive blood vessels in certain cancers; in layman’s terms, veterinarians think it increases cancer survival times. It is not commonly prescribed by veterinarians for pain relief.

Medical protocols combine piroxicam with chemotherapeutic drugs, such as cisplatin or mitoxantrone, to treat TCC, skin and oral squamous-cell carcinoma, prostatic carcinoma and certain abnormal rectal growths. The average survival time of dogs treated with a combination of piroxicam and cisplatin for oral squamous-cell carcinoma has risen to close to eight months. The average survival time of canine TCC patients treated with the medicine and mitoxantrone is just under one year, according to author and veterinarian Barbara Forney.

There are a number of medications that may interact with piroxicam, so it is important that a patient tell the prescribing doctor about all medicine and supplements taken, including over the counter medicines, vitamins, and supplements. Blood thinning medications, such as warfarin, ibuprofen, other NSAIDs, and oral steroids, may increase the risk of adverse side effects. Piroxicam usp(CAS number is 36322-90-4) may increase the toxicity of lithium, cyclosporine, methotrexate, and other drugs, so patients taking these drugs will need to be carefully monitored.

Serious side effects are an increased risk of heart attack, stroke, ulcers, and bleeding or tears in the gastrointestinal tract. Patients taking NSAIDs should seek immediate medical attention if they experience pain in the chest, weakness in one side or area of the body, difficulty breathing, or slurred speech, as these symptoms may indicate a heart attack or stroke. Stomach pain, heartburn, bloody vomit, vomit that looks like coffee grounds, or black or bloody stools may indicate serious gastrointestinal side effects, and medical attention should be sought right away.

N,N’-dicyclohexylcarbodiimide-bingding In A Chloroplast

N,N’-dicyclohexylcarbodiimide(DCC)-binding proteolipid from lettuce chloroplast membranes has been purified by a novel, rapid technique involving I-butanol extraction and ether precipitation. The reconstitution of this proteolipid in liposomes composed of lipids chloroplasts and the subsequent incorporation of bacteriorhodopsin leads to the formation of liposomes with the accumulation of the light dependent protons.

This accumulation was significantly enhanced upon addition of N,N’-dicyclohexylcarbodiimide(an organic compound with chemical formula C13H22N2) at concentrations similar to those that inhibit chloroplast adenosinetriphosphatase activity. Radioactively labeled DCC was found to be incorporated essentially into the proteolipid of the reconstituted liposomes. These results suggest that the functional unit responsible for proton channeling in the chloroplast membrane has been isolated and reconstituted in the native state.

DCC has been found to bind specifically and covalently to a small polypeptide that can be extracted in the form of a proteolipid complex. To date, however, it has not been possible to isolate a purified, defined proteolipid fraction in a state allowing reconstitution of proton-translocating activity. The present study reports the isolation of a proteolipid from lettuce chloroplasts membranes and its reconstitution into liposomes. Evidence is presented indicating that its capacity to function as a DCC-sensitive proton channel is retained during the isolation and reconstitution procedures.

The present report contributes strong supporting evidence for the role of tile DCC-binding proteolipid in proton-translocation activity. We have isolated this fraction front
chloroplast memlraIlnes and shown it to be the main N,N’-dicyclohexylcarbodiimide-binding component therein. This extends similar reports in other membrane systems.

The isolation was based on the observation that the proteolipid is the only polypeptide coml)onent of chloroplast mntmbranes soluble in water. This allows readily for its solubilization together with the majority of the membrane lipids. Subsequeritly it can be selectively precipitated from the butanol by cold ether. The total procedure and especially the butaniol solubiljfaiion can be performed in a very short time period, minimizing the exposure of the polypeptide to possible unfavorable conditions. The dletailedl characterization of this entity is still incomplete. However, from the available results the N,N’-dicyclohexylcarbodiimide(CAS: 538-75-0)-binding component appears to be a small protein having a fraction of tightly bound lipids. Its molecular weight is similar to that of equivalent fractions isolated from other sources. On the basis of yield of proteolipid and assuming complete extraction, it may be calculated that there are sonie four to six proteolipid molecules per F1 molecule in chloroplast membranes.

One important question that is not resolved is the role of the other polypeptides reported to be a part of F0. Also it is not known how the F0 is coupled to the F1 not only structurally but in its role of synthesizing ATP. One possible approach to examine such coupling would be to use the fluorescence enhancements of bound ethidium, which appears to interact selectively with the DCC-binding proteolipid.

Features Of Medications In Imidazole Class

Imidazole, appears in a number of pharmaceuticals, is characterized by a ring structure composed of three carbon atoms and two nitrogen atoms at nonadjacent positions. The simplest member of the imidazole family is itself, a compound with molecular formula C3H4N2. Labs can produce it and its derivatives, like clotrimazole and econazole, synthetically. This allows for efficient mass production in a controlled environment.

The chemical was first prepared in 1858. Other imidazole compounds have been known longer: allantoin (discovered in 1800) and parabanic acid were prepared in 1837 from uric acid. The amino acid histidine and its decomposition product histamine have the structure, as does biotin, a growth factor for both humans and yeast.

Patients may be told to take an imidazole to treat a fungal infection because it has a broad mechanism of action and is usually easy to use. It can be applied topically to skin infections as well as fungal infections in the eyes and orifices, like vaginal yeast infections. Oral formats are also available for the treatment of internal issues or persistent fungal infections that do not resolve with topical treatments. Side effects can depend on the dosage and the delivery method as well as the patient’s history, other medications, and age.

Since imidazole absorbs UV radiation at 280 nm, an elution profile measured at 280 nm while purifying a 6xHis tagged protein by FPLC will show an increase in absorbance above the background signal allowing quantitation of your protein. The absorbance of the drug can vary depending on its source and purity, but elution buffer containing 250 mM medication usually has an A280 of 0.2–0.4.

Medications in this class is well tolerated among patients. They work well and are cost-effective, which makes them popular choices for medical practitioners making recommendations or writing prescriptions. Patients can discuss alternatives if they want to consider a different medication or if they would like to learn more about available treatments. Health professionals can present options along with their associated risks and benefits to determine if an imidazole(CAS number is 288-32-4) is the best fit given the infection and the patient’s history.

However, just like other drugs, this kind of medications also have side effects. If someone takes a topical imidazole, it can cause irritation which may lead to redness, swelling, itching, and inflammation. Some people experience more severe reactions like tingling and rashes, indicating they may be allergic to the medication or an ingredient in the cream or liquid used to deliver it. Oral type medications can cause gastrointestinal upset including nausea, vomiting, and diarrhea. These symptoms are typically brief and should resolve once the patient finishes the course of medication.

Sodium Saccharin — One Common Artificial Sweetener

Sodium saccharin(molecular formula C7H4NNaO3S.2H2O), or sodium ortho-sulphobenzimide, also referred to simple as saccharin, is most commonly known as a widely used artificial sweetener. It is associated with various health defects, due to which thAccording to “Complete Confined Spaces Handbook,” the International Agency for Research on Cancer identifies sodium saccharin as a Class 2B carcinogen in humanse World Health Organization limits its daily intake to less than 0.5 milligrams per kilogram.

It is an odorless, colorless white powder with a characteristic sweet taste and is not water soluble enough to be useful in food items, but its sodium salt contains the properties necessary to make it useful in the production of artificial sweeteners. The compound is thought to be from 300 to 500 times as sweet as conventional sugar, or sucrose.

This sweetener was discovered as a derivative of coal tar by Constantin Fahlberg, who was then working at John Hopkins University in the lab of Ira Remsen. Fahlberg discovered the sweet taste and connected it with the chemical compound he had been studying. Shortly thereafter, sodium saccharin was commercialized, though it did not come into popular use until during World War I, when sugar shortages arose. Its modern popularity and place in society during the last 50 years can be traced to its use by dieting consumers who seek sugar free, low calorie sweeteners because of their presumed health benefits.

According to “Introduction to Food Toxicology”, sodium saccharin is 300 to 500 times sweeter than sugar (sucrose). The food industry uses this componuds an additive in various products. It is used as a non-nutritive sweetener and stabilizer in a variety of food and drinks. Bakeries use it to sweeten baked goods, breads, cookies and muffins. Artificially sweetened diet drinks and sodas use this salt since it dissolves readily in water. Other products that contain this compound include marzipan, plain, sweetened and fruit-flavored yogurt, jams/jellies and ice cream.

Sodium saccharin is an intermediate chemical ingredient in the production of pesticides and herbicides. It is a catalytic agent in the manufacture of anaerobic adhesive–an adhesive that stiffens without the presence of oxygen. Anaerobic adhesives are called locking compounds or sealants and are used to seal and secure close-fitting parts.
The cpmpound is useful in the electroplating industry as an additive in metalworking fluids and adhesives. The electroplating of nickel, for instance, uses saccharin as an electrolyte (a substance, which when dissolved in a solution, makes it electrically conductive). Electroplating is the process in which an electric current is applied through a solution to coat the surface of a metal with another layer of metal. The nickel electroplating industry uses it bring about a brighter finish. Gold and palladium electroplating baths also use sodium saccharin(CAS number is 128-44-9).

It has in the past been controversially identified as a carcinogen. The controversy is not due to the question of whether sodium saccharin should be classified as a carcinogen or not, but whether it is carcinogenic for humans. It has been shown to be a less than significant carcinogen in animals. Carcinogenicity in animals does not necessarily indicate carcinogenicity in humans, so it is best said that sodium saccharin is possibly carcinogenic to humans.
