History Of Carbon Monoxide

There is a long history of the carbon monoxide compound that dates back nearly eight hundred years. While the compound exists naturally and has likely been present since early in the earth's formation, it wasn't until a 14th century Spanish chemist named Arnaldus de Villanova described the gases from burning wood, which we today know as carbon monoxide. Almost three hundred years later, a Belgian chemist, Jan Baptista van Helmont, almost lost his life while inadvertently inhaling a carbon dioxide and monoxide mixture.

By the late 1700's, a French chemist named Lassone was able to take a coal material and heat up zinc oxide, which emitted a then-unknown gas that made a blue flame in his laboratory - carbon monoxide. It is unclear whether a chemist from England named William Cruikshank clearly identified carbon monoxide first at the turn of the 19th century or another English chemist, Joseph Priestly, did so a few years earlier when he identified both carbon dioxide and monoxide.

Poison value well known

While the early studies of carbon monoxide did indeed indicate that it was a poison to humans in many cases, it wasn't until the mid-1800's that French physiologist Claude Bernard specifically studied the deadly characteristics of the gas. For several centuries, many scientists have known of the poisonous nature of carbon monoxide. Tiny doses or naturally occurring amounts of carbon monoxide typically cause vomiting, nausea, an unnatural feeling of exhilaration and other effects. Of course as the amount of carbon monoxide increases, can cause unconsciousness as well as severe intestinal occlusions and eruptions. Ultimately, a high enough level of carbon monoxide can cause death.

the action of carbon monoxide poisoning is a relatively simple process. Oxygen molecules enter the lungs and are carried by red blood cells. the oxygen links up with an iron atom in a molecule called oxyhemoglobin. It is later freed by this molecule to aid other cell functions throughout the body that produce energy. When carbon monoxide enters the body this "transference chain" of oxygen is broken. Carbon monoxide bonds with the hemoglobin as does oxygen but it is much more stable (as carbonmonoxyhemoglobin) and lasts longer than oxygen, thus pushing out oxygen and essentially suffocating cells in the body. Since much less oxygen enters the body, less energy is produced and the body is poisoned.

As a cause of death

Carbon monoxide is so prevalent that, throughout the world, more people die of it than any other type of poison. Since it has no smell and is transparent, it is very hard to detect. Luckily, modern technology has caught up and carbon monoxide detectors are produced in huge volumes for home, office and industrial use. they are installed the same way that smoke detectors are. Some typical sources of carbon monoxide are unventilated charcoal fires, broken gas furnaces or stove connections and, of course, automotive and other combustible engine exhaust. this last example is the most prevalent emission of the gas in the modern world today. Often, in such overpopulated places as Mexico City or New York, car emissions are the most common carbon monoxide source with unusually high levels. those who smoke tobacco also have a direct interaction with carbon monoxide. Nearly ten percent of all of the body's hemoglobin is locked out by carbon monoxide for those who regularly smoke a pack or more a day of cigarettes.

Since the most common form of carbon monoxide emission is from cars, it is important to note the amount of carbon dioxide/carbon monoxide that emerges and how it happens. Both the temperature and the amount of oxygen in place during the reaction that generates carbon monoxide will determine its amount. Typically, carbon monoxide can form when there is little oxygen and combustion takes place at lower temperatures, so when there is more oxygen present and the temperature is higher, greater amounts are generated.

Ironically, for a number of years following the advent of the Industrial Revolution carbon monoxide was used a fuel for automobiles in parts of the world where gasoline could not be easily found. In these places, charcoal-burning devices were integrated into the combustion engine, so that when coal was burned, a high concentration of carbon monoxide was piped directly to the carburetor to be fired to move engine pistons, etc. the gas has also been used to euthanize animals and humans over the years, but the practice has largely fallen off in recent times. Carbon monoxide has also been used to drive oxygen out of substances to reduce them to their purest form. As an example, if iron oxide is used as a source material, and carbon monoxide is forced to interact with it, pure iron will result from the process. By : Alex De Mostafa

Dental Health

People begin to learn about dental health from a very young age, when teeth first begin to show up. But in spite of such early awareness, many people fail to maintain good dental health through their adult life. Good dental health comprises brushing and flossing your teeth every day, and regular visits to a dentist or dental hygienist as well. Besides, people supplement their dental care with the use of products like mouthwash or advanced mouth care systems. You should keep it in mind that the lack of adequate dental care practices will result in cavities and gum disease.

It is generally advised that you use a toothbrush with softer bristles so as to protect your gums. Some people, however, prefer power brush systems that help break up plaque and bacteria in your mouth. But it takes more than brushing to keep your teeth in good health. Some other steps need to be taken to ensure that people do not lose their teeth as they become old.

To begin with, you should understand your own oral health needs, as your oral health depends on your diet, the type and amount of saliva in your mouth, your overall health and your oral hygiene routine. Try to follow a daily routine in consultation with your dentist.

As fluoride strengthens developing teeth in kids and prevents decay in adults, toothpastes and mouthwashes containing fluoride should be used. You should brush at least twice a day, if possible three times or after every meal. You should also floss at least twice a day. Brushing and flossing will remove plaque, a complex mass of bacteria that constantly forms on your teeth.

Limit the consumption of snacks and follow a balanced diet plan. Tobacco in any form will enhance the risk of oral cancer and cause stains on your teeth. Visit your dentist regularly and get your mouth examined.

Dust Mite Information

How many sleep in your bed and carpet?

What's in house dust that's so bad?
Dust mites, Dust mite fecal pellets, Mold Spores, Pollen, Shed skin cells and Pet dander.

What are dust mites doing in my house?
They're living in upholstery, mattresses, pillows and carpets. They feed on shed human skin! Each one produces approximately 20 fecal pellet each day, and females lay 25 to 50 eggs every three weeks.

How many live in my home?
The population of dust mites increase and decrease with seasonal changes in temperature and humidity, but the average mattress is host to around 2 million of them!

What can I do?
Scientific studies of dust-allergic patients have shown that taking steps to minimize dust exposure in your indoor air environment leads to a decrease in allergic symptoms and a decrease in medication requirements.

Wash all of your sheets and blankets 1-2 times a week in HOT water to kill the dust mites and remove the dust mite allergen from your bedding. Dry your clothes on the setting that you normally use.

Vacuum often! At least 2 times per week with a High Quality HEPA Vacuum Cleaner that is sealed so dust and allergens cannot blow through the vacuum cleaners case or around the HEPA filter.

Note: Many lower quality HEPA vacuum cleaners leak lots of dust mite allergens and dusty air right through the case of the machine only to blow back into your indoor environment. These vacuum cleaners are not properly sealed!

Use Quality HEPA air cleaners in any occupied room or open space where people with allergies live or work in.

Stay away from the small, inexpensive lower quality HEPA air cleaners you will find in department stores. This is because these air cleaners will provide a very low air exchange rate per hour even in a small bedroom which will not be powerful enough to do a good job. Also, these lower quality air cleaners may cost less money up front, but the future filter replacement costs can be HUGE! Purchasing a high quality HEPA air cleaner is the way to go! This is because a high quality HEPA air cleaner can save you many hundreds of dollars in future filter replacement costs in only a few years while doing a much better job of cleaning your air.

Quality brands of HEPA air cleaners to investigate are made by Austin Air, TRACS and IQ air.

Replace your 5% efficient disposable A/C or heating filter for a cleanable/washable 90% efficient self charging electrostatic air filter. These higher quality air filters will last for many years while stopping a great deal of free flowing air borne Dust Mite allergen and other allergens from reentering back into you're A/C or heating system's duct work to blow back into your living air space.


Take and utilize these allergy control measures to greatly reduce the Dust Mite allergen and other allergens in your home or office!

Before Buying Contact Lenses

Some people out there wonder why people pay out money on expensive contact lenses or expensive glasses. If you've never worn glasses or contact lenses, then chances are that you have good eyesight. In contrast, those that don't have good vision will need to get either contact lenses or glasses in order to have near perfect vision.

In most cases, contact lenses will considerably improve your vision without having to get glasses, which is reason enough to invest in a pair of contacts. They are very lightweight, and they provide you a full range of sight and mobility.

Cheap contact lenses can be found on the Internet, or at your local opticians office. They wont set you a back a lot of money, yet they will give you the vision you need. Contacts are a great alternative to glasses, particularly for those who need glasses but hate to wear them. In you buy cheap contact lenses, it is an ideal solution to glasses, at a price, anyone can afford.

In several different ways, you can buy contact lenses. You can order them online, which is what the majority people tend to do. Companies such as offer hundreds of contact lenses and prescriptions, which they transport right to your door. When you order online you can get a great price, and then have the contact lenses brought right to you - with no travel or waiting in line required to get your contact lenses when you need them.

The best thing about buying contacts online is the fact that there is a lot more to choose from. There are a lot of different brands and manufacturers online, many of which aren't offered from your local store. Directly you can buy from a manufacturers website, or choose a third party dealer that offers a wide selection of brands and models.

With several different brands of contact lenses out there, it can be very difficult when you select your pair. Often times, your optician will suggest a brand to you, although sometimes they won't. Different brands are coming out all the time, which can make it very difficult for first time contact lens users to select the best brand for their eyes and their needs. A few examples of some of the best contact lenses manufacturers include Acuvue, Bausch and Lomb, and Progressive. These are all great choices, offering you a variety models to choose from.

Also, you can also purchase your contacts at your opticians office. If you don't have access to the internet, buying this way is a great decision. You can also purchase at a local store that sells contact lenses and glasses, such as Wal-Mart. Since they offer a variety of different contacts for those who need them, the prices are great here as well. You can also buy solution here as well, making it well worth the trip to get your contact lenses.

If you shop around, you can usually find some great deals for your lenses. The prices of the contact lenses will vary depending on the brand and type your optician prescribed. If you are buying the latest and greatest brands of contact lenses, you can obviously count on the price to be a bit higher. This is to be anticipated, as contacts cost the most when they first come out and are available for purchase.

In order to buy contact lenses, you'll require a prescription. When you go to an optician for the fitting process, he will observe your eyes and let you know if you can wear contacts. There are a few types, such as soft contact lenses and hard contact lenses. Depending on your eyes, you may have to get a unique type of contact lens. The optician will give you his recommendation, and tell you everything you need to know and do for the contacts that he will give you a prescription for.

Vitamin C in Skin Care

The integumentary system is the body's largest organ. It can also be a woman's biggest nightmare. The epidermis and its care is one of the most ubiquitous concerns of women as they age. Vitamin C is used in skin care to help prevent premature aging and damage from the suns rays. The antioxidant properties of Vitamin C allows it to bond with and remove damaging radicals in the skin from pollution, cigarette smoke and other sources. Vitamin C is also a necessary part of the body's production of collagen which is the fiber that makes tissues strong and elastic. Thus the use of Vitamin C in a daily skin care program is thought to help make your skin look full and firm. Taking care of your skin should also be one of the

biggest concerns of men since their incidence of melanoma is far greater than that of women and they are starting to spend more and more time in the tanning salons. Although men have the greatest statistical incidence of melanoma some dermatologists fear that the popularity of sun tanning beds in the female population may be bringing with it an increased development of melanoma in women. With the passage of time there may be an alarming tendency of young women to develop the sometimes fatal disease. One thing is certain though, UV rays whether from tanning beds or sun exposure is damaging in excessive amounts. Furthermore, when the sun is involved sun screen really is mandatory for prevention of its damaging effects both medical and cosmetic. But even with the best preventative measures time does take its toll. Solar radiation, pollution and exposure to various toxins damage the cells prematurely aging the skin and the natural aging process leads to a reduced production of collagen. For some corrective measures may be required. Many approaches and strategies are used in the time reversal strategy known as skin care. Alpha hydroxy acids (AHA) are a popular ingredient in many over the counter skin care products. The theory being that the acids peel away the outermost layer of skin exposing the new softer tissues underneath and the skin appears to renew and rejuvenate. Vitamins can be absorbed through the skin in creams and lotions, particularly Vitamins A and D. Vitamin C can be absorbed by the skin but the best form is one called L-ascorbic acid. This is a product that breaks down very easily especially in sunlight giving it a short shelf life. It is important to buy small amounts in dark colored or brown bottles and keep it in a dark storage place. This works by being absorbed into the epidermis and promoting the production of collagen. It also works as an antioxidant by neutralizing free radicals in the body. Because of its absorption this form of Vitamin C will not wash away but remain in the skin. Visit

Dry Skin Care

Dry skin is one of the most common skin ailments faced by people everywhere in the world. Dry Skin can be genetic or can be caused by severe weather conditions or by usage of chemical cosmetics or soaps.
In the event the skin ailment is severe as is in the case of psoriasis and eczema, the best option is to consult a physician. Medicines for such ailments must not be self-prescribed and must be only bought under the physicians advice.

If the skin is dry due to external conditions, ensuring to take a few precautions can rectify the condition. In the case of a heating system being constantly used at home, it is wise to use a humidifier. Avoid excessive sweating and scratchy clothes as these might case the dry skin to itch.

One important remedy that can easily be followed is to drink lots of water. At least two quarts of water have to be taken in per day if the skin is dry. This prevents the skin from dehydrating. The other option would be to take in lots of food containing vitamins A and B.

One sure thing that dries the skin is soaking in water. It is advised to take bath only in lukewarm water, as either hot or cold water would remove the natural oils and dry the skin.

Chemical soaps also play a big part in removing natural oils. Mild soaps or cleansers would work better on the skin. If the skin is excessively dry, it is better opt for oil-based soaps and cleansers rather than for water based ones. People should opt to use non-perfumed cleansers as they are milder compared to perfumed ones.

After taking a bath, it is wise to towel dry with gentle patting rather than vigorous wiping. This ensures the moisture is still retained in the skin to some extent.

It is also a good idea to apply moisturizer right after the bath. Some moisturizers can be applied on wet skin to retain excess moisture and can be used in case of a severely dry skin. Also, people who are exposed to the sun a lot can use a good moisturizing sunscreen.

Frequent oil massage also replenishes the body oils. Regular cleansing gives the dry skin a revitalized look. Body oil can be applied on the wet skin right after bath to give the skin a youthful look.

what is Cancer?

Cancer is a class of diseases characterized by out-of-control cell growth. There are over 100 different types of cancer, and each is classified by the type of cell that is initially affected.
Cancer is a class of diseases characterized by out-of-control cell growth. There are over 100 different types of cancer, and each is classified by the type of cell that is initially affected.

More dangerous, or malignant, tumors form when two things occur:

1. a cancerous cell manages to move throughout the body using the blood or lymph systems, destroying healthy tissue in a process called invasion
2. that cell manages to divide and grow, making new blood vessels to feed itself in a process called angiogenesis.

When a tumor successfully spreads to other parts of the body and grows, invading and destroying other healthy tissues, it is said to have metastasized. This process itself is called metastasis, and the result is a serious condition that is very difficult to treat.

In 2007, cancer claimed the lives of about 7.6 million people in the world. Physicians and researchers who specialize in the study, diagnosis, treatment, and prevention of cancer are called oncologists.
What causes cancer?

Cancer is ultimately the result of cells that uncontrollably grow and do not die. Normal cells in the body follow an orderly path of growth, division, and death. Programmed cell death is called apoptosis, and when this process breaks down, cancer begins to form. Unlike regular cells, cancer cells do not experience programmatic death and instead continue to grow and divide. This leads to a mass of abnormal cells that grows out of control.

Genes - the DNA type

Cells can experience uncontrolled growth if there are damages or mutations to DNA, and therefore, damage to the genes involved in cell division. Four key types of gene are responsible for the cell division process: oncogenes tell cells when to divide, tumor suppressor genes tell cells when not to divide, suicide genes control apoptosis and tell the cell to kill itself if something goes wrong, and DNA-repair genes instruct a cell to repair damaged DNA.

Cancer occurs when a cell's gene mutations make the cell unable to correct DNA damage and unable to commit suicide. Similarly, cancer is a result of mutations that inhibit oncogene and tumor suppressor gene function, leading to uncontrollable cell growth.

Carcinogens are a class of substances that are directly responsible for damaging DNA, promoting or aiding cancer. Tobacco, asbestos, arsenic, radiation such as gamma and x-rays, the sun, and compounds in car exhaust fumes are all examples of carcinogens. When our bodies are exposed to carcinogens, free radicals are formed that try to steal electrons from other molecules in the body. Theses free radicals damage cells and affect their ability to function normally.
Genes - the family type

Cancer can be the result of a genetic predisposition that is inherited from family members. It is possible to be born with certain genetic mutations or a fault in a gene that makes one statistically more likely to develop cancer later in life.

Other medical factors
As we age, there is an increase in the number of possible cancer-causing mutations in our DNA. This makes age an important risk factor for cancer. Several viruses have also been linked to cancer such as: human papillomavirus (a cause of cervical cancer), hepatitis B and C (causes of liver cancer), and Epstein-Barr virus (a cause of some childhood cancers). Human immunodeficiency virus (HIV) - and anything else that suppresses or weakens the immune system - inhibits the body's ability to fight infections and increases the chance of developing cancer.
What are the symptoms of cancer?

Cancer symptoms are quite varied and depend on where the cancer is located, where it has spread, and how big the tumor is. Some cancers can be felt or seen through the skin - a lump on the breast or testicle can be an indicator of cancer in those locations. Skin cancer (melanoma) is often noted by a change in a wart or mole on the skin. Some oral cancers present white patches inside the mouth or white spots on the tongue.

Other cancers have symptoms that are less physically apparent. Some brain tumors tend to present symptoms early in the disease as they affect important cognitive functions. Pancreas cancers are usually too small to cause symptoms until they cause pain by pushing against nearby nerves or interfere with liver function to cause a yellowing of the skin and eyes called jaundice. Symptoms also can be created as a tumor grows and pushes against organs and blood vessels. For example, colon cancers lead to symptoms such as constipation, diarrhea, and changes in stool size. Bladder or prostate cancers cause changes in bladder function such as more frequent or infrequent urination.

As cancer cells use the body's energy and interfere with normal hormone function, it is possible to present symptoms such as fever, fatigue, excessive sweating, anemia, and unexplained weight loss. However, these symptoms are common in several other maladies as well. For example, coughing and hoarseness can point to lung or throat cancer as well as several other conditions.

When cancer spreads, or metastasizes, additional symptoms can present themselves in the newly affected area. Swollen or enlarged lymph nodes are common and likely to be present early. If cancer spreads to the brain, patients may experience vertigo, headaches, or seizures. Spreading to the lungs may cause coughing and shortness of breath. In addition, the liver may become enlarged and cause jaundice and bones can become painful, brittle, and break easily. Symptoms of metastasis ultimately depend on the location to which the cancer has spread.
How is cancer classified?

There are five broad groups that are used to classify cancer.

1. Carcinomas are characterized by cells that cover internal and external parts of the body such as lung, breast, and colon cancer.
2. Sarcomas are characterized by cells that are located in bone, cartilage, fat, connective tissue, muscle, and other supportive tissues.
3. Lymphomas are cancers that begin in the lymph nodes and immune system tissues.
4. Leukemias are cancers that begin in the bone marrow and often accumulate in the bloodstream.
5. Adenomas are cancers that arise in the thyroid, the pituitary gland, the adrenal gland, and other glandular tissues.

Cancers are often referred to by terms that contain a prefix related to the cell type in which the cancer originated and a suffix such as -sarcoma, -carcinoma, or just -oma. Common prefixes include:

* Adeno- = gland
* Chondro- = cartilage
* Erythro- = red blood cell
* Hemangio- = blood vessels
* Hepato- = liver
* Lipo- = fat
* Lympho- = white blood cell
* Melano- = pigment cell
* Myelo- = bone marrow
* Myo- = muscle
* Osteo- = bone
* Uro- = bladder
* Retino- = eye
* Neuro- = brain

How is cancer diagnosed and staged?
cancer. Imaging techniques such as X-rays, CT scans, MRI scans, PET scans, and ultrasound scans are used regularly in order to detect where a tumor is located and what organs may be affected by it. Doctors may also conduct an endoscopy, which is a procedure that uses a thin tube with a camera and light at one end, to look for abnormalities inside the body.

Extracting cancer cells and looking at them under a microscope is the only absolute way to diagnose cancer. This procedure is called a biopsy. Other types of molecular diagnostic tests are frequently employed as well. Physicians will analyze your body's sugars, fats, proteins, and DNA at the molecular level. For example, cancerous prostate cells release a higher level of a chemical called PSA (prostate-specific antigen) into the bloodstream that can be detected by a blood test. Molecular diagnostics, biopsies, and imaging techniques are all used together to diagnose cancer.

After a diagnosis is made, doctors find out how far the cancer has spread and determine the stage of the cancer. The stage determines which choices will be available for treatment and informs prognoses. The most common cancer staging method is called the TNM system. T (1-4) indicates the size and direct extent of the primary tumor, N (0-3) indicates the degree to which the cancer has spread to nearby lymph nodes, and M (0-1) indicates whether the cancer has metastasized to other organs in the body. A small tumor that has not spread to lymph nodes or distant organs may be staged as (T1, N0, M0), for example.

TNM descriptions then lead to a simpler categorization of stages, from 0 to 4, where lower numbers indicate that the cancer has spread less. While most Stage 1 tumors are curable, most Stage 4 tumors are inoperable or untreatable.
How is cancer treated?

Cancer treatment depends on the type of cancer, the stage of the cancer (how much it has spread), age, health status, and additional personal characteristics. There is no single treatment for cancer, and patients often receive a combination of therapies and palliative care. Treatments usually fall into one of the following categories: surgery, radiation, chemotherapy, immunotherapy, hormone therapy, or gene therapy.

Surgery is the oldest known treatment for cancer. If a cancer has not metastasized, it is possible to completely cure a patient by surgically removing the cancer from the body. This is often seen in the removal of the prostate or a breast or testicle. After the disease has spread, however, it is nearly impossible to remove all of the cancer cells. Surgery may also be instrumental in helping to control symptoms such as bowel obstruction or spinal cord compression.

Radiation treatment, also known as radiotherapy, destroys cancer by focusing high-energy rays on the cancer cells. This causes damage to the molecules that make up the cancer cells and leads them to commit suicide. Radiotherapy utilizes high-energy gamma-rays that are emitted from metals such as radium or high-energy x-rays that are created in a special machine. Early radiation treatments caused severe side-effects because the energy beams would damage normal, healthy tissue, but technologies have improved so that beams can be more accurately targeted. Radiotherapy is used as a standalone treatment to shrink a tumor or destroy cancer cells (including those associated with leukemia and lymphoma), and it is also used in combination with other cancer treatments.

Chemotherapy utilizes chemicals that interfere with the cell division process - damaging proteins or DNA - so that cancer cells will commit suicide. These treatments target any rapidly dividing cells (not necessarily just cancer cells), but normal cells usually can recover from any chemical-induced damage while cancer cells cannot. Chemotherapy is generally used to treat cancer that has spread or metastasized because the medicines travel throughout the entire body. It is a necessary treatment for some forms of leukemia and lymphoma. Chemotherapy treatment occurs in cycles so the body has time to heal between doses. However, there are still common side effects such as hair loss, nausea, fatigue, and vomiting. Combination therapies often include multiple types of chemotherapy or chemotherapy combined with other treatment options.

Immunotherapy aims to get the body's immune system to fight the tumor. Local immunotherapy injects a treatment into an affected area, for example, to cause inflammation that causes a tumor to shrink. Systemic immunotherapy treats the whole body by administering an agent such as the protein interferon alpha that can shrink tumors. Immunotherapy can also be considered non-specific if it improves cancer-fighting abilities by stimulating the entire immune system, and it can be considered targeted if the treatment specifically tells the immune system to destroy cancer cells. These therapies are relatively young, but researchers have had success with treatments that introduce antibodies to the body that inhibit the growth of breast cancer cells. Bone marrow transplantation (hematopoetic stem cell transplantation) can also be considered immunotherapy because the donor's immune cells will often attack the tumor or cancer cells that are present in the host.
Hormone therapy

Several cancers have been linked to some types of hormones, most notably breast and prostate cancer. Hormone therapy is designed to alter hormone production in the body so that cancer cells stop growing or are killed completely. Breast cancer hormone therapies often focus on reducing estrogen levels (a common drug for this is tamoxifen) and prostate cancer hormone therapies often focus on reducing testosterone levels. In addition, some leukemia and lymphoma cases can be treated with the hormone cortisone.
Gene therapy

The goal of gene therapy is to replace damaged genes with ones that work to address a root cause of cancer: damage to DNA. For example, researchers are trying to replace the damaged gene that signals cells to stop dividing (the p53 gene) with a copy of a working gene. Other gene-based therapies focus on further damaging cancer cell DNA to the point where the cell commits suicide. Gene therapy is a very young field and has not yet resulted in any successful treatments.
How can cancer be prevented?

Cancers that are closely linked to certain behaviors are the easiest to prevent. For example, choosing not to smoke tobacco or drink alcohol significantly lower the risk of several types of cancer - most notably lung, throat, mouth, and liver cancer. Even if you are a current tobacco user, quitting can still greatly reduce your chances of getting cancer.

Skin cancer can be prevented by staying in the shade, protecting yourself with a hat and shirt when in the sun, and using sunscreen. Diet is also an important part of cancer prevention since what we eat has been linked to the disease. Physicians recommend diets that are low in fat and rich in fresh fruits and vegetables and whole grains.

Certain vaccinations have been associated with the prevention of some cancers. For example, many women receive a vaccination for the human papillomavirus because of the virus's relationship with cervical cancer. Hepatitis B vaccines prevent the hepatitis B virus, which can cause liver cancer.

Some cancer prevention is based on systematic screening in order to detect small irregularities or tumors as early as possible even if there are no clear symptoms present. Breast self-examination, mammograms, testicular self-examination, and Pap smears are common screening methods for various cancers.

Tips for Healthy Eyes

Eyesight is something that many of us take for granted. Yet every year, thousands of people lose their best vision due to injury or disease. There are parts of the eye that, once damaged, cannot be repaired or replaced. It is important to take good care of your eyes to keep them as healthy as possible.
We recommend you follow these tips to preserve your vision and protect your eyes.
Get an annual check-up by an eye care professional. At Eye Care Associates, we not only check your need for eyeglasses or contacts, we screen for a variety of potential conditions and diseases of the eye, including glaucoma, macular degeneration and cataracts. If you have a family history of eye disease, diabetes, or high blood pressure, you may need to visit a specialist twice a year.
Consult your doctor immediately if you notice any changes in your vision. Trouble signs include: double or blurred vision, halos around lights, parts of letters or words missing from a printed page, difficulty judging depth perception on stairs or curbs, faded or distorted print, washed-out or faded colors, inability to see faces clearly, difficulty seeing when going from light to dark, sparks of light appearing off to the side, sudden pain in one or both eyes, or sudden appearance of "floaters" in your line of vision.
Protect your eyes from ultraviolet (UV) rays, dust, wind and bright lights. Be sure to wear sunglasses that protect your eyes from UV rays. The UV blocking capacity should be clearly stated on the label or manufacturer's warranty.
Eat a healthy diet. Research suggests that diets rich in antioxidants (leafy green vegetables and citrus fruits), carotenoids (carrots, kale, and spinach), zinc (beef, pork, and lamb), and selenium (fish, shellfish, and red meat) play a beneficial role in helping to reduce the severity of certain age-related eye diseases.
Take care to avoid accidental injury to the eyes. Wear protective goggles when doing yard work, using power tools or playing sports. If a foreign body enters your eye, DO NOT RUB your eye; instead, wash it with plenty of water. If acid or any other chemical gets into your eyes, immediately wash them with plenty of water, seek emergency care (emergency room visit) or see your doctor as soon as possible.
Make sure there is sufficient light for any task, especially reading.
Use common sense when watching television or working at a computer.
Keep a distance of 8 - 10 feet between your eyes and the TV screen. Blink your eyes frequently while watching a program. Do not turn off the lights in the room. Give your eyes a break every half hour if you are watching a long program.
People who work long hours at the computer often complain of double vision, temporary shortsightedness and visual fatigue. Some suggestions that may help include:
* Use a screen filter to cut down on glare
* Adjust the brightness and contrast of the monitor
* Take frequent breaks
* Blink frequently to keep your eyes well lubricated
* Periodically, look up from the screen and focus on an object in the distance to reduce eye fatigue.

anti depression drugs

For someone in a state of depression gaining an understanding of all the drugs for depression can be a challenging if not impossible task. With all of the talk of potential side effects such as headaches, dry, mouth, dizziness, stomach upsets, and oh yes depression medications that can cause depression it is easy to see how someone could just throw their hands up in overwhelming disgust.
Depression occurs when the biology of in the brain becomes abnormal; when chemical conversations between neurons break down. Put simply the brain runs out of resources to manage events such as stress. Once again the experts are split on exactly what is happening, with some believing that there aren't enough brain communication chemicals to get the message out while others believe that depression is more of a situation where neurotransmitters (chemical messagers) just don't function properly. Different drugs for depression act on different neurotransmitters in different ways.
In this informational article titled "Anti Depression Drugs" we will briefly explore four commonly prescribed drug categories for depression and how they work.
*Tetricyclics: These drugs raise brain concentrations of the neurotransmitters serotonin and norepinephrine by blocking their reabsorption by the nerve cells (neurons) that release them. About a 60% success rate is seen though multiple weeks are needed before results are noticed. While the success rate is acceptable the side effects are worth noting; drowsiness, blood pressure reduction leading to dizziness, hand tremors, nausea and vomiting, blurred vision, dry mouth, problems with urination, rapid heart rate, and constipation.
*Dopamine reuptake inhibitors: The most widely prescribed anti depression drug in this category is Wellbutrin (Bupropion) which seems to be effective in decreasing the reuptake of the neurotransmitter dopamine. It tends to produce fewer side effects than the Tetricyclics but in rare instances can cause seizures.
*Monoamine oxidase (MAO) inhibitors: Like tricyclics, MAO inhibitors increase brain levels of norepinephrine, serotonin, and dopamine, in this case by blocking the action of the enzyme MAO, which generally interacts with three neurotransmitters. Good results have been seen especially in depression cases accompanied by anxiety, panic attacks, out of control eating, or excessive sleeping. MAO inhibitors can cause many of the same side effects as the tricyclics along with a few others. If you are considering this option be sure and ask your doctor about the risks involved. Examples: Marplan (Isocarboxazid) and Nardil (Phenelzine)
*Serotonin and nor epinephrine re uptake inhibitors: Like tricyclics these anti depressant drugs work by raising brain concentrations of the neurotransmitters serotonin and nor epinephrine. They seem to be very effective especially when older patients are involved. Possible side effects include nausea, drowsiness, dizziness, and dry mouth. Examples: Trazodone (Desyrel) and Venlafaxine (Effexor)
In summary, we have just scratched the surface on anti depressant drug treatments. But there are a couple of conclusions that are fairly obvious, first, not all anti anxiety drugs work for everyone and secondly each comes with some risk for side effects.
Additionally, many natural health minded individuals are choosing to add herbal remedies for depression to their tool box of depression fighting solutions. If you have been searching for a natural and affordable way to treat mild to moderate depression this is an option worth investigating further.

Home Remedy for Pimples

There is nothing worse than waking up in the morning, looking in the mirror, and there it is in all its glory. A brand new shiny pimple stuck on your face. It’s a never ending battle, no sooner do you get one cleared away then a new pimple pops up in a different spot. No matter what you do or the latest treatment you try your pimples just keep coming back.

So what causes these embarrassing outbreaks? Propionibacterium acnes; otherwise known as bacteria.

This bacteria, which normally lives on the skin, is able to grow in plugged hair follicles or pores. Normally sebum, and oily substance that flows to the skins surface, keeps the bacteria from entering the follicle. Pimples develop when the sebum, cells called keratinocytes that line the follicle and the hair itself form a plug allowing the bacteria to enter and grow in the plugged follicle. The body reacts to this invasion by sending white blood cells that cause inflammation. Eventually the wall of the plugged follicle disintegrates and the infection spreads into the surrounding skin leading to lesions and pimples.

There are several factors which lead to these outbreaks of pimples and for some people make an already bad condition worse.

• Hormones – This is particularly true of teens going through puberty as well as a womans hormone changes during her monthly menstrual cycle, pregnancy and even the birth control pills she is taking.

• Oil from skin products and cosmetics.

• Pressure from tight or restrictive clothing, sports helmets, backpack straps and anything else that does not allow the skin to breathe.

• Pollution and high humidity

• Squeezing and picking at pimples.

• Scrubbing your skin to hard.

• Stress.

Contrary to popular belief the foods you eat do not lead to the formation of pimples. There is little scientific evidence that proves that chocolate and greasy foods cause outbreaks of pimples. This does not mean that you should eat a bunch of un-healthy food either. A proper diet will help your body deal with any of the stresses that may lead to outbreaks in a much easier way.

A home remedy for pimples includes the following:

• Cleaning your skin gently, particularly your face. It is best to use a mild cleanser twice a day. Do not scrub your face with a rough scour pad and do not use an astringent except for on very oil spots. You can make your pimples worse if you aren’t gentle with your skin care.

• Don’t pick at and pop your pimples. As fun as this may be for some people it can lead to scarring and dark skin blotches.

• Shaving carefully. Make sure your razor is sharp and thoroughly soften your whiskers with warm soap and water. Nicking existing blemishes can make your pimple outbreaks worse.

• Don’t over expose your skin to the sun. While it may appear that a nice tan makes your pimples go away in reality it only makes them less visible. The risks of over exposure to the sun, rapid skin aging and skin cancer, far outweigh any benefit a tan will have for your condition.

• Cosmetics. It is best to choose cosmetics that are oil free. Look for labels that say noncomedogenic. This means they will not lead to clogged pores.

Just about everyone deals with outbreaks of pimples during their life. Nearly 80% of people between the ages of 11 and 30 are affected by them at least once in their life. Most people tend to see their outbreaks disappearing in their thirties; however, some people in their 40s and 50s continue to suffer from this skin problem.

A home remedy for pimples is about following some simple guidelines and common sense. If you are careful with your skin care and follow these tips chances are your pimples will disappear.

The Emotional Cause of Asthma

Asthma is also influenced by certain emotions such as laughing, crying, anger, panic, etc. But many in the medical community believe there is no proof people with asthma are any more psychologically disturbed than their non-asthmatic peers. However, it is not possible to have an illness without it having an emotional or trauma component associated with it. Our brain and body is not a split organism where our brain and body work independently of each other.
Having asthma is most likely related to birth traumas where the newborn is being suffocated by the birth process or has a difficulty coming out thus weakening the lungs and the bronchioles. Or, possibly where the parents were over protective or dominating, or demanding to the point of, in a sense, suffocating the child.
And, there are many other asthmatic scenarios that could weaken a persons lungs and bronchioles during childhood. You might know what yours is.
In his book, How to Get Well, 1974, Paavo Airola, Ph.D., says,
“Extensive studies show that there are two basic causes of asthma: one, the typical allergic reaction to one or more allergens; two, psychic factors. Doctors agree that many young asthmatics (according to studies, about 25%) have in common a ‘deep-seated emotional insecurity and an intense need for parental love and protection’. When emotional causes are suspected, these must be dealt with before biological and nutritional treatments can be effective.�
Emotions and feelings, such as apprehension, concern, anxiety, and panic can cause muscular tension and contraction around the bronchioles. Over a long time, these tensions can cause muscle spasms and weakening of the bronchioles, which can then lead to asthma as an adult.
In his book, Cleanse & Purify Thyself, 1998, Richard Anderson, N.D., N.M.D., says,
“Our own research indicates that Love is the great key. When we understand that Love is the natural state of our beings and when Love is not flowing through our beings every moment, than some other emotion or concept is interfering. These interferences are usually emotions of great intensity or some quirk in our point of view, such as the habit of judging conditions, things, or people in negative ways, and most of the time they are unconscious. One of the activities we all need to initiate is to remove these conscious and unconscious negative emotions so that Love may flow through us. Here in lies one of the most important point in this book
For many healers of the past it was clear that childhood trauma and the lack of love provided an atmosphere where illness could develop. Asthma sufferers need to look for and heal that emotional component that prevents them from healing so that they can start the asthma healing.

How to Live With Your Asthma

If you have asthma, managing it is an important part of your life. Controlling your asthma symptoms means staying away from things that bother your airways and taking medicines as directed by your doctor. If you have asthma, it is important to learn how to take care of yourself and learn what natural remedies can help you and what diet will reduce your asthma symptoms.
It is important that you work with your doctor to make an action plan that you are both happy with. As part of this, you will need to:
* Tell your doctor about all other medications, drugs, and natural remedies you are taking, in case one of them affects your asthma.
* Follow your asthma action plan and have regular checkups.
* Learn to use your medication correctly. Ask your doctor to teach you how to use your inhaler. This is very important. If inhalers are not used correctly, less medication gets into the airways.
You also need to learn to identify and avoid the things that can worsen or trigger your asthma symptoms. These include:
* If animal dander is a problem for you, keep your pet out of the house and/or at least out of your bedroom and wash your pet often, or find it a new home.
* Do not smoke or allow smoking in your home.
* If pollen is a problem for you, stay indoors with the air conditioner on when the pollen count is high.
* To control dust mites, wash your sheets, blankets, pillows, and stuffed toys once a week in hot water. You can get special dust proof covers for your mattress and pillows.
* To prevent colds and flu keep your immune system up and strong by taking natural remedies.
* If you get asthma when you exercise or do routine physical activities like climbing stairs, work with your doctor to find ways to be active without having asthma symptoms. Physical activity is important.
* Try to keep humidity levels in the home between 30 and 50 percent. High humidity can promote growth of biological agents that may trigger asthma episodes. Use exhaust fans or open windows in the kitchen or bathroom areas when cooking, using the dishwasher, or taking showers. Make sure clothes dryers are vented to the outdoors, and use a dehumidifier in the basement if necessary.
* Avoid using humidifiers
* Minimize exposure to combustion particles and gases that can cause breathing difficulties for people with asthma. Have combustion-powered furnaces, stoves, or heaters checked yearly to make sure they are operating properly. Change furnace filters according to the manufacturer's instructions, or every month or two during periods of use.
* Avoid sprays like deodorants, perfumes, or air fresheners, odours from paint
* Keep the house clean to reduce allergens like microscopic dust mites, pollen, and animal dander. Use an allergen-proof comforter and encase mattresses and box springs in vinyl covers. Wash bedding frequently in hot (130°F) water. Try to eliminate cockroaches. Try to keep pets out of the bedrooms of family members with asthma. Use a high-efficiency vacuum system that is vented to the outside to clean the house. If possible, remove the carpeting, drapes, and all upholstered furniture from the bedrooms of those suffering from asthma.
Finally, you should adopt a healthy lifestyle. Eat a healthy diet rich in fruits and vegetables and low in fats and sugars, get enough rest, exercise regularly, try to find ways to manage stress in your life. And, find out what natural remedies will help you reduce your asthma attacks and symptoms.
If your asthma seems to be getting worse, see your doctor. You may need to change your medication or do other things to get your asthma under control.
