Lead Fact Sheets

Lead is a metallic chemical element which is classified among the poor metals of the periodic table of elements. It is a soft, pliable metal that is silvery-white in color when freshly cut, but on exposure to air quickly acquires a dull gray appearance due to the formation of a layer of oxide. This element does not typically appear in a pure form in nature. It has a wide range of historical and current applications, and many consumers own products which contain this chemical.

Humans have been using lead for thousands of years. It was also the material of choice for movable type from the 1400s, when Gutenberg invented the movable type press, to today; several foundries still cast its type and other equipment for use with letterpresses. One of the most infamous historical uses of it was in Roman plumbing and pewter, an alloy which was used to make many household goods including cups and plates. Numerous cultural artifacts contain the substance, often in the form of metal alloys, and the ancients were obviously very familiar with the metal, though unfortunately not with its negative health effects.

Lead is the heaviest stable element, a distinction that used to belong to bismuth — element number 83 — until it was found to be very slightly radioactive. One of the most important physical properties of this metal is its ability to absorb high frequency electromagnetic radiation, such as x-rays and gamma rays. This is due to its high density and the large number of electrons in its atom.

The uses for lead are myriad. The resistance to corrosion and malleability make it a popular additive to alloys, and it is also used in bullets, soldering material, radiation shields, and some paints. This metal has also historically been used as an additive in glass, which is why some antique and modern glass is not safe to eat or drink from. Because it is extremely soft, the substance is very easy to work, and early metalsmiths could manipulate product with minimal heat.

Although occasionally found in its elemental state, the main lead ore is galena, or lead sulphide (PbS); other lead ores include cerussite — lead carbonate (PbCO3) — and anglesite — lead sulfate (PbSO4). Ethionine ester is an xcellent selection performance and special separation effect for molybdenum sulfide, lead sulfide, zinc sulfide, copper sulfide, etc.

Chronic lead poisoning has been a significant problem due to the widespread use of Pb in applications that have allowed it to enter the environment. People should try to minimize exposure as much as possible by working in safe environments and disposing of old paint, chemicals, and other potential sources of toxins responsibly.

A Common Protease Inhibitors Of HIV

Prezista is a brand name for the generic drug darunavir. Darunavir is a medication that prevents replication of human immunodeficiency virus (HIV) in the body. It is an antiviral medication classified as a protease inhibitor.A doctor usually prescribes this medication as part of combination therapy for a patient with HIV infection to prevent the infection from progressing to full-blown acquired immune deficiency syndrome (AIDS). This is not a cure for the disease and will not prevent a patient from spreading it to others.

This drug is in the second generation of protease inhibitors. Before starting darunavir, it is important to go over all current medications, including herbal preparations and over-the-counter drugs. A doctor can check for harmful drug interactions and adjust the patient’s drug regimen as needed. This drug can interact negatively with other drugs, and some medications may make it less effective. Patients on this drug may also find it helpful to carry around an informational card discussing current medications and their dosages, so doctors can take this information into account when providing treatment.

The drug is available in the form of a tablet intended to be swallowed whole. Patients must not break, crush, or chew the tablet. Dosages should be taken at the same time each day to maintain constant levels of the drug in the body. Typically, the physician will prescribe one to two doses daily, which must be taken with a meal and a full glass of water or milk. The patient should not take Prezista exclusively. It is essential for the patient to take ritonavir and the other HIV medication along with Prezista. It is also essential for the patient to avoid skipping doses or discontinuing the medication without the doctor’s approval — doing so can make the HIV infection much more difficult to control.

Many patients tolerate darunavir therapy very well. Common side effects include gastrointestinal upset, rash, changes in distribution of body fat, and headaches. Depending on the drug cocktail a patient uses to manage HIV infection, other side effects may occur as well.Patients taking the drug must discuss all other medications and supplements they take with their doctors. This drug should never be taken with St. John’s wort.

People taking darunavir are still infectious and need to take precautions to protect other people. This is especially important for emergency services personnel like firefighters, police officers, and paramedics. Health care providers should be made aware of HIV infection so they can exercise precautions, especially when the patient is bleeding.

Is Liquid Soap Healthy?

Different liquid soaps are intended for use in different situations. Antibacterial product is a form of liquid soap which includes ingredients which are designed to fight bacteria. It can be used in the kitchen, office or bathroom. The efficacy of the soap can vary, depending on the ingredients and how it is used, with some killing up to 99% of bacteria, while others tend to be less robust. It is also possible to obtain it from medical suppliers, or to make it at home, for people who are comfortable and familiar with soap making.

People use antibacterial liquid soap on their hands and bodies because they are concerned about the spread of bacteria, or because they want to prevent bacterial infections. On the body, antibacterial liquid soap can prevent Staphylococcus infections of the skin, and it is sometimes used to manage skin conditions like acne and sunburn. In the case of handwashing, the soap reduces the number of bacteria on the hands, making it difficult to spread bacteria through direct contact or the handling of shared objects like doorknobs.

Some liquid soap is designed to be very good for cosmetic uses. Cosmetic liquid soaps can either be labeled for use on a specific part of the body, such as the hands or face, or can be for general-purpose use. This includes soap that has a rough, grainy texture intended to exfoliate the skin. Other cosmetic soaps, such as those made with shea butter, are meant to help tighten the skin.

Some people like to use antibacterial products at home because they are concerned about cleanliness. In fact, the members of a shared household tend to have the same bacteria, so the spread of bacteria is not a major risk unless someone comes home with a bacterial infection which could be spread to other members of the household. For management of skin conditions, however, antibacterial soap can be extremely useful.

Many people feel the best soaps for a household, especially one with children, are soaps that are environmentally friendly. Environmentally friendly soaps can be safer for children and pets than soaps with harsh chemicals, although most liquid soaps are non-toxic. 2-Butoxy ethanol is a primary ingredient of this product.

One advantage to using liquid soap is the fact that it can be poured into a soap dispenser. The widespread use of antibacterial products has raised some concerns among medical researchers. Some people fear that frequent use breeds resistant bacteria, by killing off organisms which are vulnerable and allowing more virulent organisms to flourish. For the reason, it can be a good idea to change brands frequently.

Different Ways Of Improving Bone Density

If you take care of your bones, you will be more likely to remain independent throughout your life. So it is possible to improve bone density at any age. But the sooner you start working on strengthening your bones, the better. There are many ways to enhance the bone density, it depends on yourself that which one is better. It is never late to do this, just from now on.

Through Diet
Typically western diet contains insufficient calcium, too few vegetables and fruit, coupled with excessive amounts of salt, caffeine and alcohol – all of which can contribute to poor bone mineral density. A balanced diet high in vegetables, whole grains, beans, some dairy products and fruit in moderation, supplies the key nutrients required for optimal bone health.

Eating adequate serves of vegetables and fruits in the diet is an important way of attaining the complete spectrum of minerals and vitamins necessary for good bone health. It is recommended that adults consume 5-7 serves of vegetables, and 2-3 serves of fruit per day.

Through Vitamin D and Calcium Supplements
Vitamin D plays an important role in maintaining serum calcium levels and the modelling and remodelling of bone. Without vitamin D bones become thin, brittle and misshapen. Most of your body’s calcium is stored within your bones, which increases bone strength. Your body also uses calcium to keep nerves, muscles and your heart functioning.

It is said that calcium is best absorbed in amounts of 500 milligrams or less at one time, so take your supplement in divided doses, the National Institute of Arthritis and Musculoskeletal and Skin Diseases suggests. Your body does not absorb all the calcium you ingest in your diet. Vitamin D increases calcium absorption in the small intestine. Taking both calcium and vitamin D supplements will increase calcium absorption.

Through Medicine

A common medication used to improve bone density is risedronate sodium, the the brand name is Actonel. Actonel falls into the classification of a bisphosphonate, a drug that slows bone loss by preventing bone breakdown. Bone is in a continual state of remodeling, with older bone breaking down and new bone laid down. As you age, bone breakdown increases, which is why the risk of osteoporosis increases with age. Bisphosphonates like Actonel slow the process.

Both bisphosphonates and vitamin D and calcium can increase bone density; the two treatments may work best together, Without adequate calcium intake, bisphosphonates will not be effective. Without adequate vitamin D, calcium won’t be well-absorbed.

Palladium Jewelry Facts

Palladium is a lustrous silvery white metal with the atomic number 46 and chemical abbreviation of Pd. Because the metal is extremely rare, palladium is considered to be a precious metal, and it can command a high price on the open market. It is used in electronics, jewelry, and certain other industries. The growing popularity of the metal jewelry has led many to wonder about this “new” metal. This sleeper silver-white metal owes its existence to another, better-known precious metal, and its renewed popularity to better technology.

The metal was discovered in 1803 by William Hyde Wollaston, who named it palladium after the asteroid Pallas. Jewelers used it for jewelry as early as the Victorian era. After World War II, when the war effort called for platinum, the chemical emerged as a viable alternative white metal, especially for use in fine jewelry and wedding jewelry. The re-emergence of platinum for jewelry in the 1980s and 1990s made lower-cost alternative white metals return in popularity as well.

The metal resists tarnish, and is extremely ductile, meaning that it takes readily to working. When palladium is cold worked, the tensile strength greatly increases. The asteroid, in turn, was named for a Greek Goddess of Wisdom. It often occurs in conjunction with platinum, and it is frequently associated with gold, nickel, and copper. Its true, white-silver appearance rarely tarnishes and needs no plating to retain its color.

is anything but a newcomer to the jewelry market. Two factors, however, contributed to the disappearance of the substance on the jewelry market during the last half of the 20th century. These were the difficulty to create a palladium alloy for mass-market jewelry, and the increasing popularity of gold jewelry.

White gold, which is actually yellow gold alloyed with other white metals, made a comeback, as did silver. However, the fact that white gold is rarely “white” and retains a yellowish cast unless plated with rhodium, and the fact that sterling silver is neither precious nor as durable as gold or platinum, opened the market for the reappearance of palladium.

The Photography Industry

Photography as a process can be dated as far back as the 1600s, but only became popular during the 1800s, when taking portraits and preserving people on paper became fashionable. Since then, the photography industry has become widely accessible to the masses. It is a continually growing sector that deals with producing goods and services related to photographs, images, and sometimes films as well.

Photography was not fully accepted as a fine art until after the middle of the 20th century. In fact, it was not until the 1950′s that it became acceptable to frame a photograph for a museum or gallery exhibition. Before this time, prints of photographs were simply pasted onto a board and hung. Alternatively, they were printed with a white border and pinned to walls instead of hung.

From the 1970′s to the 1990′s it became more and more accepted and popular to print photographs on a large scale, give them a glossy finish, and hang them in frames just as if they were paintings. Since the middle of the 20th century, fine art photography has gone from a barely accepted medium that was only afforded the crudest of frames, to a well-respected modern art that is often displayed with great respect.

According to a February 2011 report, wedding photography tops the most in-demand service for the photography industry. It can also be classified under the tertiary sector that hugely involves offering of services instead of products, and professional photographers and studios earn an income by offering their services to cover many events. Other services that the industry can provide are advertising and public relations. Large billboards displaying a company’s product, along with a celebrity endorser, can be seen along streets and highways. Newspapers and magazines also rely on photographs.

The photography industry is also a significant part of the field of arts and design. Every product and service that the industry produces will always be tied to the skill and creativity it requires. Ultimately, the industry is valuable because of its ability to capture an object, an event, and even a memory. Barium bromide(BaBr2, CAS number is 10553-31-8) is a precursor to chemicals used in photography and to other bromides.

Other fields such as forensics, medicine, and fashion also rely on the photography industry in various ways. Many digital cameras already include features like anti-blink, smile detection, and face recognition. The computer and programming industries have also been in tandem with the industry, in order to make improvements on gadgets, particularly camera models. The commercial photography industry has especially been booming due to the many computer programs and software that can change and tweak images, brightening the light settings and even “erasing” some minor flaws in the picture.

Distinctive Ginkgo

Ginkgo, better known as ginkgo biloba, is a tree that grows leaves which can included in natural ginkgo health products. The function of Ginkgo Biloba is a topic of debate. As some studies have clearly shown that Ginkgo extracts are certainly useful for the treatment of some conditions, while others have been more inconclusive. Experts have studied this natural health product so long, and they continue to examine its uses and safety.

These trees have distinctive features. Ginkgos are so diffreent that they are literally placed in their own class, with no living relatives. When mature, these trees can get quite tall, with distinctive fan-shaped leaves which make them popular ornamentals; some people call ornamental Ginkgos “Maidenhair Trees.” In Asia, Ginkgo Biloba has been cultivated for centuries, and botanists have also uncovered several stands of wild trees. The tree is also extremely hardy, and the trees will happily survive in extreme conditions which prove to be overwhelming for other trees and plants.

In addition,we should’t forget its soft fleshy seeds which smell rather unpleasant. It is said that the seeds have beneficial properties for human health, although most Ginkgo Biloba extract comes from the leaves. In China, these seeds have been harvested for food uses, often in auspicious or traditional dishes. The leaves are processed to extract their essence, which can be sold as a liquid or in the form of powders and capsules.

Users of ginkgo biloba supplements have reported ginkgo biloba benefits such as a positive effect on dementia and Alzheimer’s disease. Ginkgo benefits for Alzheimer’s disease patients may include a delayed onset of dementia and improvement in daily functioning. Improvement in cognitive functions such as thinking, memory and learning may occur with ginkgo use. Some people have reported ginkgo effects such as improvement of depression and social interactions.

Age-related macular degeneration is a retinal condition that often causes blindness as patients with this condition get older. The use of ginkgo may help people with age-related macular degeneration keep their eyesight for a longer period of time. In some cases, people have reported ginkgo benefits related to eye problems. Glaucoma patients have experienced improved vision with regular use of ginkgo in some cases. Flavonoids in ginkgo biloba may improve health conditions of the eye that are related to the retina.

Risedronate Sodium Used For Bones

Risedronate sodium, also known as Actonel, risedronic acid or more simply as risedronate. It is a medication patients can take to increase bone density and prevent breakdown of bone over time. A doctor may prescribe it to a patient with osteoporosis, and it can also be part of the treatment for Paget’s disease of bone.  It is also sometimes recommended for treating Paget’s disease of bone, which results in errors in the way new bone is formed.

This medication interferes with the resorption of bone, slowing the rate of bone breakdown. Patients can take a tablet daily or once a week, with the weekly dose being higher. Risedronate sodium is not recommended in patients with low blood calcium, as the slowdown of bone breakdown will result in even less available calcium for the body. It may be necessary to take calcium or vitamin D supplements while on the medication to make sure the body has enough nutrition. With fewer osteoclasts present, less bone matter is destroyed and bones may retain a certain level of integrity. There is much higher risk of damage to the esophagus if this position is not maintained. A single pill can cause damage to the stomach or esophagus if not properly digested.

There are different types of bisphosphonates. Actonel is an easy one to take because it is orally administered. It does have very special instructions and must be taken when a person will be sitting upright for at least half-an-hour after taking it. It also can’t be combined with meals or many other medications. Dosage may vary too, depending on the person, and some people use this drug once weekly, while others use it daily.

If risedronate sodium is not suitable for a patient, other medications to improve bone density are available. The doctor can prescribe an alternative and see if the medication meets the needs of the patient. Patients may also combine their medication with activities like swimming and gentle exercise to build up bone mass and muscle strength, useful for preventing fractures.

For most people, osteonecrosis of the jaw will not occur, but there are mild side effects that may affect those who take Actonel. Some may experience some stomach upset, particularly flatulence, constipation, diarrhea, or acid indigestion. Others have a small amount of back pain or arthritic-like pain in the joints, while others experience headache. These are considered mild, but if they continue, reporting them to a doctor could be of use. There are other bisphosphonates that a person might tolerate better.

A Common Chemotherapy Drug

Fludarabine is a chemotherapy drug used in the treatment of cancer. It is most commonly utilized for patients with B-cell chronic lymphocytic leukemia, although it can be used for other cancers involving the blood. It is usually provided as part of a combination therapy regimen with other chemotherapy drugs.

The pyrimidine analogue, cytarabine, has been used effectively against a wide variety of acute leukemias. The success of cytarabine prompted a search for other potentially useful analogues. Fludarabine is a fluorinated analogue of adenine which is relatively resistant to deamination by adenosine deaminase. It is rapidly metabolized by deoxycytidine kinase to 2FaraATP which inhibits DNA synthesis by inhibition of DNA polymerases, and prevention of elongation of DNA strands through direct incorporation into the DNA molecule. It also inhibits RNA polymerase and protein synthesis.

This medication is in a class of chemotherapy drugs that work by attacking metabolic processes within the cancer cells. The drug inhibits the growth of cancerous cells and eventually forces cancer cells to die. It can be very effective in patients who have not responded to primary treatment.

Chemotherapy drugs are very strong, and fludarabine can come with serious side effects. As it attacks cancerous blood cells, it can also damage healthy cells. The drug causes anemia, with the lowest blood cell counts occurring approximately two weeks after the medication ha6s been administered. Patients on this drug have severely weakened immune systems and are highly vulnerable to infections, particularly pneumonia. Prophylactic drugs may be offered to prevent infection if a patient’s oncologist is concerned.

In a dosefinding study, severe irreversible central nervous system effects, including blindness, demyelination, coma and death, were seen in 36% of patients receiving four times the recommended dose for chronic lymphocytic leukemia. Symptoms appeared from 21 to 60 days post dosing. These effects are rare (0.2%) at the recommended dose. Fludarabine(CAS No. 21679-14-1) in combination with pentostatin (deoxycoformycin) results in an unacceptably high incidence of fatal pulmonary toxicity, and concomitant use is contraindicated.

One serious potential side effect is tumor lysis syndrome. This complication can also be seen with some other chemotherapy drugs. It occurs when cancer cells rapidly break up. This can cause kidney failure. If a patient has difficulty urinating or notices decreased urine output after a fludarabine treatment, the doctor should be notified. People will need to take precautions to avoid exposure to infectious organisms. Even mild infections can be dangerous because the patient’s immune system lacks the ability to successfully eliminate fungi, bacteria, viruses, and protozoans.

Surfactants In Daily Life

In chemistry, the term “surfactant” is used to describe a chemical that reduces the surface tension of another compound and increasing the contact between the liquid and another substance. There are a wide variety of these products, which work with oil, water, and an assortment of other liquids. Many companies manufacture a range of them for various purposes, ranging from soaps to inks. As a result, they are found in a number of everyday household item.

The term is a compound of “surface acting agent”, referring to the fact that a surfactant interacts with the surface of a liquid to change its properties. They work through a process known as “adsorption,” which means that they accrete on the surface of a liquid, creating a film which reduces its surface tension.

Soap, shampoo, hair conditioner and toothpaste all contain surfactants which gently cleanse the scalp, skin, hair and teeth. These compounds create a pleasantly foamy reaction when mixed with water. The suds and bubbles help the water get beneath oil, dirt and debris, allowing the unwanted compounds to be washed away during rinsing. Additionally, the products are found in shaving creams where the decrease in surface tension reduces the friction generated by the razor blade, resulting in a smoother shave.

Dish-washing liquids and dishwasher detergents are two of the most common sources for kitchen surfactants. In these compounds, they create loads of suds and leave dishes sparkling clean by breaking up baked-on grime and dissolving fats and oil.

Surfactants can also work as lubricants, as is the case with shaving a cream, a product which makes it easier to run a razor along the skin to remove unwanted hair. They are also used in sanitizing products, anti-fogging liquids, adhesives, emulsifiers, and fabric softeners, among numerous other substances. Dodecylbenzenesulfonic acid(referred to as LABSA, CAS No. 27176-87-0) is a common active agent in the production of surfactants. In some cases, a surfactant may be toxic or pose a health risk, depending on the materials it contains, and it is a good idea to read labels to make sure that it is used properly.

The term “surfactant” is also used in the medical community to refer specifically to a substance secreted by the cells which line the lungs. Pulmonary product makes it easier for people to breathe by reducing surface tension in the lungs. Without the subsatnce in the lungs, people would have trouble breathing, and their breathing would be much noisier.

SLES: Uses & Hazards

Sodium laureth sulfate is also called sodium lauryl ether sulfate (SLES). Commercially, it’s available as a mixture of the general formula CH3(CH2)10CH2(OCH2CH2)n-OSO3Na, where “n” varies but represents an average value or a mean. While it is both a detergent and a surfactant, it’s especially known as a foaming agent. The use of sodium laureth sulfate in consumer products, such as toothpaste, is controversial. does not consist of one molecular formula.

Detergent manufacturers use sodium laureth sulfate in products because of two reasons: this chemical can be easily acquired and has a strong amphiphilic base. This means the chemical compounds are compatible with both water and fat. Thus it easily mixes with water and acts a formidable stain exterminator. Sodium laureth sulfate forms the basic ingredients of various surface cleaners. Even cosmetic companies use this chemical in frugal amounts in cosmetic products.

However, the use of SLES is not limited to detergent cleaners only. Various types of cosmetics like soaps and cleansing milks have sodium laureth sulfate as a component. This chemical makes detergents and cleaning agents powerful and strong on stains and hard grease, also effectively wiping them out of existence if sodium laureth sulfate based cleaners are applied.

SLES can be used to stop several viral infections. Herpis simplex and HIV virus infections can be prevented with SLES. It has been clinically proven that SLES is effective as a microbicide and studies are underway to establish a method which will use this chemical to curb infections. Other than keeping viruses at bay, SLES(CAS No. 68585-34-2) is also prevalent in laxatives, medicine for heart disease and in aspirin.

Effects To Environment
Despite of the above uses, the manufacturing process alters the natural ingredients with ethoxylation. Ethoxylation is a process that uses ethylene oxide, which is a known human carcinogen. The surfactant becomes contaminated with byproducts of the manufacturing process.

According to the David Suzuki foundation, depending on manufacturing processes, sodium laureth sulfate may be contaminated with considerable amounts of 1,4-dioxane. 1,4-dioxane does not degrade easily and may remain in the environment long after it is rinsed down the shower drain.

Folinic Acid Used In Chemotherapy Treatment

Folinic acid, also commonly referred to as calcium folinate or leucovorin, is not a chemotherapy drug, but it’s often given as part of chemotherapy treatment – either to make the chemotherapy more effective or to reduce the risk of side effects. This fact sheet has information about leucovorin when it’s given with the chemotherapy drugs fluorouracil (5FU) or methotrexate.

Leucovorin is often given with 5FU chemotherapy to treat cancers of the colon, rectum and other parts of the digestive system. Adding leucovorin has been shown to increase the effectiveness of the 5FU. Leucovorin may also be given with the chemotherapy drug tegafur-uracil, which is similar to 5FU.

Leucovorin is also commonly given with methotrexate chemotherapy, which is used to treat many different types of cancer. It’s mainly given with higher doses of methotrexate and can help reduce the side effects. It is sometimes known as ‘folinic acid rescue’.

Medications that treat cancer typically work by destroying abnormal cancer cells; however, in the process they may also damage healthy cells and result in potentially dangerous side effects, such as difficulty fighting off infections, anemia, increased risk of bruising or bleeding, and damage to the kidneys. Folinic acid is typically prescribed as part of a cancer treatment program because the drug has been found to be effective in some patients at preventing harmful cancer medication from damaging healthy cells, while still allowing the abnormal cancer cells to be destroyed.

Although calcium folinate(CAS No. 1492-18-8) is generally considered safe and effective at treating cancer treatment side effects, the medication may potentially cause some side effects of its own. These side effects may include hives, rash, difficulty breathing, diarrhea, or convulsions. It is usually recommended to seek immediate medical attention if any of these side effects occur since they can be potentially life-threatening; however, side effects from the medication tend to be rare.

Certain people are typically not advised to take folinic acid due to the preexisting conditions that may render the medication ineffective. People who are also suffering from kidney disease along with cancer, may have a higher amount of cancer medications in their systems because their kidneys may not able to remove it from the body in a timely manner; therefore, medications to fight against the side effects of cancer treatment may not be able to work as effectively against the higher amounts remaining in the body.

Health Hazards Of Glutaraldehyde

Glutaraldehyde, also called as glutaric dialdehyde or Pentanedial, is a toxic chemical that is used as a cold sterilant to disinfect and clean heat-sensitive medical, surgical and dental equipment. It is found in products such as Cidex, Aldesen, Hospex and so on. It is a colorless, oily liquid with a pungent odor which exhibits low level hazards to human health.

The disinfectant properties of glutaraldehyde make it useful especially in medical applications where sanitation is a paramount concern. Many pieces of equipment are sensitive to steam and heat treatments that might otherwise be used for sterilization and call for the use of chemical disinfectants like glutaric dialdehyde. X-ray technicians also use it as a hardening agent for developing x-ray film.

Glutaraldehyde is used in a limited number of applications, rather than as a general disinfectant. Specific applications include use as a disinfecting agent for respiratory therapy equipment, bronchoscopes, physical therapy whirlpool tubs, surgical instruments, anesthesia equipment parts, x-ray tabletops, dialyzers, and dialysis treatment equipment.

Health Hazards
The chemical is an irritant to the skin, eyes, lungs and throat. Irritants like glutaric dialdehyde cause dermatitis, rashes, swelling and constriction of airways to exposed tissue. The most commonly cited effect is asthma-like symptoms caused by glutaraldehyde vapor entering the lungs and throat. Irritation is usually caused by substances of 2% aqueous glutaraldehyde or stronger.

Glutaraldehyde is a sensitizer. This means some workers will become very sensitive to glutaric dialdehyde(CAS No. 111-30-8) and have strong reactions if they are exposed to even small amounts. Workers may get sudden asthma attacks with difficult breathing, wheezing, coughing, and tightness in the chest. Prolonged exposure can cause a skin allergy and chronic eczema, and afterwards, exposure to small amounts produces severe itching and skin rashes. It has been implicated as a possible cause of occupational asthma.

Always consult medical professionals or poison control if contact or inhalation occurs, but basic measures recommended by the MSDS for glutaraldehyde are as follows. For Inhalation, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention. If swallowed, immediately call a poison control center or doctor.

Main Chemicals Used In Milk

Chemical preservatives are not permitted in any milk products, according to Dairy Farmers of America. Instead, pathogens and harmful bacteria are controlled by combination of heat treatment (pasteurization), refrigeration and protection from light. Additionally, most milk sold for public consumption is homogenized, which prevents the creme from separating.

Despite this, preservatives are still used in dairy heard improvement milk samples when refrigeration is not practical. In fact, their use is required under these circumstances in most states. Some of these preservatives are toxic, and milk that contains these preservatives is not meant for human consumption.

The totally unnecessary consequences that are revealed by your recent official inquiry are scandalous. Dairy men evidently—and must constantly—find the milk they have to sell, not only in an advanced, but also dangerous state of fermentation, which, in self-interest, they can only, however, temporarily suppress by the processes of drugging, late-refrigeration and other disorganising practices, through neglect in the country of purifying and cooling the milk at once when drawn warm from the cow. There are plenty of simple portable appliances to use for the purpose, so why should not farmers have them, and rural ice depots near railway stations for refrigeration of milk, as well as Continental, and notably American, country milk producers?

Potassium Dichromate is a low-cost preservative that has color to indicate its presence in the milk. It is easily dispersed throughout the milk sample. It is a toxic substance that tends to deteriorate the fat in samples, and also pollutes the sewer system. Formaldehyde is another low-cost preservative easily dispersed through milk samples. However, it was found unsuitable for test milk samples because it interfered with fat tests in electronic equipment.

Bronopol(C3 H6 BrNO4, CAS No. 52-51-7) is also a low-cost preservative that is easily dispersed through milk samples. It has low toxicity levels. Bronopol must be stored under dry conditions, and does not prevent the growth of yeast in unrefrigerated samples. Hydrogen peroxide has a low toxicity level, is inexpensive, and is easily dispersed through milk. The disadvantages of hydrogen peroxide are that it has a short preservation time and adds no color to the samples.

By all means let the prohibition be utterly complete, and thus allow the consumer to drink nature’s production and not chemical compounds. In the world the use of any drugs has long been prohibited, and our milk is superior and never complained about, and were drugs permitted a general protest would result.

Methods Of Water Disinfection

Many people in most developing countries suffer from the inadequacy or hazardous condition of public water supplies. A wide variety of known waterborne diseases, including those associated with children’s diarrhea, are rampant. This prompted the establishment of the International Drinking Water Supply and Sanitation Decade. It aims at providing about 90% of the human population with an adequate, safe community water supply by 1990.

Water is important to every living creature; humans need potable water, so if your water source is questionable, you will need to disinfect your water. In situations such as when you are camping, you may need to purify water before drinking it or using it. If you are getting water from a stream, river or some wells, filter the water first to remove sediments and then allow the water to settle before proceeding to disinfect it.

Adding either iodine tablets or tincture of iodine to the water is another way to purify it, states the EPA website article Emergency Disinfection of Drinking Water. Iodine in tablet form contains the correct dosage to add to drinking water. You can find the tablets at most drug or sporting goods stores. If you are using the tincture, add 5 drops of approved Pharmacopeia tincture for each quart of water. If the water is cloudy, add 10 drops and leave the water to stand for 30 minutes or more. The usual dosage is one tablet per quart of water, but always follow the directions on the label.

Disinfectants are substances which are capable of killing microorganisms. 2, 2-Dibromo-2-Nitroethanol(DBNE, CAS No. 69094-18-4) belongs to the bromine series compound, is one kind of highly effective anticorrosion disinfectant, widely applies to the industry circulating water and so on. A variety of surfaces can be treated with disinfectants, including textiles, which can be washed in disinfectant solutions, along with floors, counters, and walls made from materials like wood, tile, glass, concrete, and so forth.

Boiling Water
Boiling water kills disease-causing organisms such as giardia lamblia and cryptosporidium. Boiling the water may cause it to taste flat–to make it taste better, pour the water from one container to another four or more times. According to the EPA website article Emergency Disinfection of Drinking Water, you should vigorously boil filtered water for one minute before drinking it. If you live above altitudes of one mile, boil the water for three minutes.  Let it stand for two hours or add a pinch of salt per quart.

Information On Two Antithrombotics

Clopidogrel is used in the prevention and treatment of heart attack, stroke, blood clots, myocardial infarction, transient ischemic attacks and acute coronary syndrome (ACS). It is marketed as clopidogrel bisulfate (clopidogrel hydrogen sulfate), most commonly under the trade names Plavix. The drug prevents platelets in blood from clustering. This helps to prevent blood from forming blood clots.

Clopidogrel bisulfate is used to lessen the chance of heart attack or stroke. It is given to people who have already had a heart attack or stroke or to people with other blood circulation problems that could lead to a stroke or heart attack. A heart attack or stroke may occur when a blood vessel in the heart or brain is blocked by a blood clot. Clopidogrel reduces the chance that a harmful blood clot will form by preventing certain cells in the blood from clumping together.

The U.S. Food and Drug Administration (FDA) is reminding the public that it continues to warn against the concomitant use of Plavix and omeprazole because the co-administration can result in significant reductions in clopidogrel’s active metabolite levels and antiplatelet activity. This information was added to the drug label of Plavix in November 2009, and has been the source of continued discussion in the medical literature.

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary.

Patients at risk of heart attacks or strokes, who are given Plavix to prevent blood clots, will not get the full anti-clotting effect if they also take omeprazole. Omeprazole is found in prescription products (Prilosec, Zegerid, and generic products) and over-the-counter products (Prilosec OTC, Zegerid OTC, and generic products).

Results of the trial demonstrated that treatment with clopidogrel bisulfate(CAS No. 135046-48-9) reduced the risk of heart attack, stroke or cardiovascular death by 20% in subjects with mild heart attack or unstable angina. A variety of drugs that inhibit platelet function have been shown to decrease morbid events in people with established atherosclerotic cardiovascular disease as evidenced by stroke or transient ischemic attacks, myocardial infarction, or need for bypass or angioplasty.

With regard to the proton pump inhibitor (PPI) drug class, this recommendation applies only to omeprazole and not to all PPIs. Not all PPIs have the same inhibitory effect on the enzyme that is crucial for conversion of Plavix into its active form. Pantoprazole (Protonix) may be an alternative PPI for consideration. It is a weak inhibitor of CYP2C19 and has less effect on the pharmacological activity of Plavix than omeprazole.

Mandelic Acid Uses

Mandelic acid is an aromatic alpha hydroxy acid from Prunus dulcis var. amara, or bitter almond with the molecular formula C6H5CH(OH)CO2H. It is a white crystalline solid that is soluble in water and polar organic solvents. Since the molecule is chiral, it exists in either of two enantiomers as well as the racemic mixture, known as paramandelic acid.

It has been used as a urinary disinfectant for those with chronic urinary tract infections. It is also used dermatologically to repair skin damage from prolonged sun exposure and as an acne treatment. Low doses of mandelic acid are included in some formulations of skin care products and available without a prescription. Medical supervision is required for higher concentrations. Side effects are usually mild, but depend on the concentration used in treatment.

For Sensitive Skins
Mandelic acid is recommended for sensitive skins and darker skins that do not tolerate other alpha-hydroxyacids with a smaller molecule, which may penetrate deeper inside the skin and irritate sensitive skins. The mandelac product line can help people with sensitive skin and blemishes, pigmentation, ageing skin. Some patients in clinical trials showed an up to 50% reduction in the pigmentation of melasma using a 10% mandelic acid lotion for four weeks.

For Urinary Tract Infections
When used as a treatment for urinary tract infections, mandelic acid is combined with methenamine and marketed as mandelamine. This medication is activated in the urine and turns it from a growth-producing medium to a growth-inhibiting medium by making the urine more acidic. It is the formaldehyde created from the acidic urine that actually kills the virus or bacteria. Users may experience gastrointestinal side effects, skin rash, or, rarely, blood in the urine. According to its manufacturer, mandelamine is safe for long-term usage.

Other Medical Uses
The antibiotic properties of this acid, its ability to speed up skin exfoliation, and slow the production of sebum, make this AHA useful treatment for acne. This may be the treatment of choice for adults who want to treat skin blemishes and reduce the appearance of fine lines. This AHA has been used to reduce acne scars as well. (R)-(-)-Mandelic acid(C8H8O3, CAS No. 611-71-2) is one of the three types of this acid.

Some cosmetic companies include mandelic acid in their skin care products. The products have low doses of the AHA, ranging from 10 to 20%. Cleansers, lotions, skin toners, and sunscreen products may be purchased individually or in kits. These products are primarily for people with mild skin problems.

Iron Around Our Life

Iron(Fe) is a metallic chemical element which has been utilized by humans for centuries. The metal has played such an important role in human history that an entire era, the Iron Age, is named for it. For much of recorded human history, its have been common practice. Today, the uses for the chemical are greater than they have ever been. You probably interact with it in numerous alloys and forms every day, since the element is a ubiquitous part of life on Earth.

Pure iron is a silvery white, very lustrous metal. It is extremely malleable and ductile, which is one of the reasons it has been used by humans for so long, since the substance does not require complex technology to be worked. The metal is identified with the symbol Fe on the periodic table of elements, and it has the atomic number 26. Alloys which contain this element or act like Fe are called ferrous metals, in a reference to the Latin ferrum, which means “iron”.

Popular Uses
Combinations of iron and steel, sometimes referred to as alloyed steel, are also one of the more common uses. The combined material is ideal for use in construction. For example, alloyed steel is often used for the framework of a number of storage buildings, as well as in the construction of some parts of automobiles and the hulls of large carrier and passenger ships. Because the material holds up so well to a variety of temperatures and pressure, the alloy is just right for all forms of construction.

Cast iron is one of the uses for iron(CAS No. 7439-89-6) that many people would not think of being without in their kitchens. The even heating quality of it makes it a perfect material for skillets, Dutch ovens, cake pans, cornbread trays and a number of other forms of cooking hollow ware. The art of properly seasoning substance for use in the kitchen is something that is often passed down from generation to generation within a family.

Better Food Sources
Red meat, especially liver, is one of the best sources of iron. A single serving of liver contains around seven milligrams of Fe, with red meat in general containing between two and four milligrams of this chemical a serving. White meats contain Fe, typically half a milligram to three milligrams a serving, and eggs are also good sources of iron.

Are Oil Additives Miracle Cure?

Engine life and performance rely heavily on the lubricating materials used inside engine components. Engine oil additives are sometimes sarcastically referred to as
“mechanic in a bottle”. This term refers to the marketing message, not to mention the belief shared by many people, that oil additives can improve gas mileage, increase horsepower, and fix other engine problems. They are designed to enhance engine performance and protect inner workings; but certainly no miracle cures.

Tests conducted in 1998 by the NASA Lewis Research Center examined the actual effects of oil additives on engine condition and performance using different marketed brands. Bearing surface contact, sedimentation and reduced wear-and-tear effects were the conditions observed during testing. Researchers concluded the overall effects of oil additives could actually be damaging to engine components in the long term, according to Modern Car Care. Ultimately, the question as to whether or not additives do work may depend on a user’s perspective, and the risks he’s willing to take.

For example, many companies make an oil additive that is supposed to stop leaks. This is an exaggeration of the truth. Engine seals often dry up, shrink, and crack with age, causing oil leaks to occur. Oil additives that are meant to stop these leaks are actually formulated to condition or re-moisturize these seals. The idea is that the conditioning will cause the seal to resume its original shape, therefore reversing the cause of the leak.

There are two problems with this theory. One, rubber seals that have already dried up and lost their shape will never be the same again, no matter how much reconditioning additives are used. Furthermore, no matter how well the seals are re-moisturized, cracks that have formed will always be there, necessitating replacement rather than a miracle cure.

Oil additives are made up of synthetic materials designed to reduce the wear and tear on the car engine, according to Modern Car Care, a car care resource site. And while there are many different brands available for use, polytetrafloeraethylene (PTFE) is the common active ingredient used in each brand. 4-Aminophenol(C6H7NO, CAS No. 123-30-8) is another active ingredient used in additives.

Another type of oil additive that is often found on the market is for cleaning sludge and buildup from the inside of an engine. These products often make a number of claims, for instance that they will increase the efficiency of the engine, boost gas mileage, and even increase horsepower. However, no matter how good these oil additives are, they cannot give the car horsepower or gas mileage that it did not have in the first place.
