R124 and R134 are two different refrigerant chemicals used to operate air conditioning systems. Based on chlorofluorocarbons, different refrigerants contain different combinations of chemicals and have different effects on the environment when accidentally released. While all chlorofluorocarbons, or CFCs, can damage the ozone layer and contribute to the "greenhouse effect," scientists have continued to try different combinations of refrigerants, including joining R124 and R134, to find a safer alternative.
Canine melanoma is a type of cancer characterized by malignant lesions on the dog’s skin, sometimes appearing in the mouth or on the lips. As with humans, melanoma in dogs is a life-threatening disease, as cancerous cells may spread throughout the body, invading vital organs. Canine melanoma has a poor prognosis, but there are numerous treatments available, including surgery, radiation, chemotherapy drugs and other medications. In February 2010, the U.S. Department of Agriculture approved a therapeutic vaccine for oral canine melanoma. Consult with a board-certified veterinary oncologist to discuss your dog’s treatment options.
A GOG score, or Gynaecologic Oncology Group score, is a figure that attempts to quantify the risk of gynaecological cancer after radical hysterectomy surgery. It's estimated that if you have a GOG score greater than 120 three years after surgery, your risk of recurrence is 40%. To calculate the score you need to know three things: the tumor size, the lympho-vascular space involvement (LVSI) and the relative-risk for depth of tumor invasion.
Psychologist have studied people's traits since the earliest days of the discipline, particularly in efforts to determine which traits are genetically predetermined and which are learned. One of the earliest psychologists to study traits was Carl Jung, whose work led to the development of the Myers-Briggs Type Inventory personality test, which divides traits into broad categories based on Jung's four functional types of thinking, feeling, sensation and intuition.
One of the buzzwords in the alternative health and medicine fields is "detox" (short for "detoxification"). Practitioners say detox cleanses a person's body of toxins and disease. Some people promote detox as beautification for the skin as well as treatment for dermatological problems such as rashes. However, different authorities have differing opinions about detox and its relationship with the skin.
Most of the material you can find on this topic is oriented toward heterosexual women only and fails to differentiate between seriously good and seriously bad relationships. Serious relationships that are bad can be seriously scary and miserable. However, there are signs that apply to men or women, of whatever sexual orientation, that point to a seriously good relationship.
"Eat your vegetables" is an age-old term that is more important now than ever before, especially regarding anti-aging. When it comes to the top age-fighting foods, all but one are plant-derived. According to nutritionists and famed doctors like Mehmet Oz, eating a wide range of veggies and fruit -- and all colors -- is the key to keeping the body and skin healthy and fighting the aging process.
Tanning is the natural response to skin that has been exposed to sunlight over time. The sun's radiation causes the skin to produce more melanin, which makes the skin brown as a protection against burning. Excessive tanning can weaken the body's immune system and lead to skin cancers. It can also cause permanent brown spots, wrinkles and other signs of premature aging. If you have a tan that you wish to get rid of, you have limited options.
Genetically modified (GM) crops are, as the name suggests, grown from seeds that are modified in laboratories at the genetic level. This modification can mean crops that are more resistant to weeds and pests, crops that require fewer fertilizers, crops that produce higher yields and crops that are more nutritious. The problems that arise are that the effect of these genetically modified crops on human health and the environment is, as yet, largely unknown and that the genes that produce them are patented by the companies that create them which makes the seeds more expensive.
The word lesion is a general term that refers to any kind of physical abnormality that affects your body. Skin lesions can be anything from a cancerous growth to an acne scar. They are categorized according to their size from gross lesions which are visible, to histological lesions which can only be seen through a microscope. The process for getting rid of different types of lesions will vary, but a few basic principles will help you get rid of annoying, and in some cases, harmful skin lesions.
The skin is the largest organ of the human body, providing protection from foreign bodies such as chemicals, microorganisms and sunlight. Alongside providing a protective layer topped by a layer of cells called the epidermis, the skin controls the temperature of the body and allows human beings the sense of touch.
Melanoma carcinoma (malignant melanoma) is a highly dangerous skin cancer caused by exposure to ultraviolet rays. Melanoma appears as a mole-like formation on the surface of the skin, but it can grow deeper into other layers of the skin if it remains undetected. If caught and treated at an early stage, melanoma is usually not fatal. When examining moles or other skin growths for melanoma, there are five main warning signs to be aware of. While it is important to regularly examine your skin for possible melanomas, it is absolutely necessary to consult a physician anytime there is a suspicious…
Cancer is an nonspecific name for a group of diseases in which cells reproduce and divide uncontrollably. This process can create tumors and gain the ability to metastasize, or spread throughout the body. Carcinomas and malignant melanomas are two types of skin cancer, which are named depending on their ability to metastasize and the location in which they occur. Many remedies have been suggested to treat skin cancers, such as vitamins C, D and E, green tea, beta carotene, selenium and zinc, all of which have varying levels of efficacy. However, always consult an oncologist or dermatologist to treat skin…
Dead skin cells and trapped oil combine to clog your pores and form pimples. They can also stretch out your pores, making them look larger. Many over-the-counter acne products are available that can help treat this problem. Develop a regular, gentle cleansing routine to keep your pores clear and stop acne from forming.
Prostate cancer is cancer of the prostate gland. Prostate cancer is ranked fifth among the most common cancers worldwide. It accounts for almost one-third of all cancers in men, with more than 180,000 new cases every year. The most important risk factors of prostate cancer include age, race, family history and diet.
Squamous cell carcinoma is a common form of skin cancer; only basal cell carcinoma occurs more frequently. It is most common in older adults, but it is becoming more common in people under 40. It is strongly associated with unprotected exposure to UV radiation, such as that produced by the sun and by tanning lamps and beds.
Maintenance/consolidation refers to an approach to dosing schedules for patients who are receiving chemotherapy to treat cancer. The two terms ("maintenance" and "consolidation") have historically been used interchangeably to refer to the same sequence; modern literature therefore uses the hybrid term to avoid confusion.
The sun produces ultraviolet (UV) radiation, which humans cannot see or feel. UV radiation causes skin cancer, premature aging, immune system suppression and cataracts. Window glass blocks some types of UV rays, but some UV rays are able to pass through glass.
Since December 2000, scientists have been investigating the use of viper venom in the treatment of cancer. A protein, contortrostatin, was isolated from the southern copperhead. Dr. Francis Markland of the University of Southern California found that contortrostatin worked in two ways to prevent the spread of cancer in mice: it inhibited cancer cells from latching onto other cells, which is how cancer spreads, and at the same time, contortrostatin also prevented new blood vessels from being formed, which is what feeds new cancer growths. While snake venom proteins are already in use as drugs for heart disease and stroke,…
Melanin is a naturally occurring substance in the body that creates pigment in skin, hair and the iris of the eye. The darker your skin, the more melanin you possess. If you want to treat a skin condition or darken your skin tone for cosmetic purposes, know that there is no artificial method to create melanin. The only factors that affect melanin production are genetics, adequate vitamin D intake and the degree of your exposure to ultraviolet rays.
Abnormal growths in the palms of a person's hands may be a result of various skin conditions. These conditions vary and may be a simple infection or a serious disease. It is best to seek medical attention for any abnormal growths for proper treatment.
The external human ear provides protection for internal ear structures. It also helps to funnel sounds into the ear, and to filter sounds that we do not need to hear.
It may be tempting to think you are safe from the harmful cancer-causing rays of the sun while sitting in your conservatory, or by a window, but it isn't so straightforward. A window does not offer you 100 percent protection.
According to the Skin Cancer Foundation, skin cancer will affect one in five Americans in their lifetime, so it is important to protect yourself from the sun's rays at all times --- even when you are indoors or in the car.
Manapol is a nutritional supplement product, extracted from the aloe vera plant, and used to boost the body's immunity. It is also used to treat a variety of other conditions based on its compounds that contain anti-viral strength.
Consuming collagen has been proved to increase the body's formation of collagen. Given that the substance acts as a support structure for the skin, it can benefit the skin and bones. Nevertheless, it is not thought to prevent wrinkles.
Melanoma is the most deadly form of skin cancer, and the rates of diagnosis are increasing annually. Many cancer patients seek different kinds of assistance during the course of their diagnosis and treatment.
A bronzed complexion can make you look and feel great. But there are huge risks associated with tanning. Skin cancer, heat stroke and dehydration are consequences if you spend too much time in the sun without adequate sun protection. Health professionals recommend sunless tanning such as tanning spray as a healthy alternative to exposing yourself to the sun's glare. In moderation and when done sensibly, you can achieve a suntan outdoors. Vitamin D from the sun can provide a sense of well-being. When getting a suntan outside, limit the time you spend exposed to the sun.
Scalp bumps can be annoying, itchy or unsightly. A range of factors can contribute to bumps on the scalp, and a variety of over-the-counter solutions often can be effective in removing them.

The herbicide napropamide is used as a control method for broadleaf grasses and annual grasses. Cranberries, strawberries, peppers, tomatoes, eggplants and tobacco are regularly treated with napropamide; 368,000 lbs. of napropamide are applied to crops each year.
The sun's utraviolet rays, known as UV rays, possess the potential to damage the skin, cause premature aging, wrinkling and skin cancers. Skin damage and the risk of developing skin cancer increase with repeated overexposure to the sun.
Sunbed, also called tanning bed or artificial tanning booth, refers to equipment that produces UVA radiation. Exposure to UVA radiation causes a person's skin to tan. UVA rays from sunbeds are less likely to cause sunburns than the radiation in sunlight, according to the Environmental Protection Agency. However, UVA radiation is not safe.
Studies in Japan on barley grass have shown that it protects human cells and animal DNA from X-ray damage and some cancer-causing chemicals. This is probably because barley grass contains high levels of nutrients and chlorophyll. Young barley leaves have a strong ability to absorb nutrients from the soil. Research at the Institute of Preventive Medicine in Washington has found barley grass juice can improve stamina, skin texture and sexual energy and can reduce addictions.
Since ancient times, people have extracted oils from peppermint and spearmint plants to treat common ailments like indigestion, headaches and anxiety. However, ingredients in both oils are toxic, and if used incorrectly, these oils can cause serious health problems.
There are several great ways to cook with what are considered cancer-fighting foods. Enjoy the benefits of some foods with help from a registered dietitian and nutritionist in this free video on cooking with cancer-fighting foods.
Failure to use sunscreen can cause more than a bad sunburn, it can possibly lead to skin cancer. Even cloudy or cold days can expose skin to ultraviolet rays from reflected light, according to the Mayo Clinic.
Being told you have cancer is always a life-changing moment. According to the Melanoma Support and Education Foundation, 54,000 people are diagnosed with malignant melanoma in the United States each year and 8,000 will die. Blondes, redheads and those with fair skin and freckles are most likely to get melanomas, but everyone is vulnerable. Malignant melanoma is frightening, but there are programs to assist you or loved ones in fighting this disease.
Many contact cement products are solvent-based and contain a chemical called methylene chloride, also called dichloromethane. This chemical is a volatile, colorless liquid with a mildly sweet odor. Exposure to methylene chloride can be through inhalation and skin contact. OSHA considers this chemical to be a potential occupational carcinogen---a cancer causing agent. Try one of the safer alternatives for your projects.
A diagnosis of metastatic lymph cell carcinoma is devastating. This fatal disease causes a lot of pain and discomfort, and the treatments involved often have strong side effects, such as weight loss, lethargy and vomiting. While cancer is automatically associated with death, metastatic lymph cell carcinoma is not always terminal. The earlier it is caught the more likely it is to be successfully treated.
Several class action suits were filed during 2006 by plaintiffs alleging that major sunscreen manufacturers were guilty of selling snake oil to unsuspecting consumers. The plaintiffs alleged that the sunscreen makers misled them to believe sunscreens protected them against both UVA and UVB rays, but there is actually only UVB protection and no protection against harmful UVA rays. The lawsuits were bifurcated and are currently part of class action proceedings.
Myoepithelial carcinoma (MC) is a rare cancer of myoepithelial cells that are found in salivary, sweat and mammary glands. MCs are typically salivary gland cancers, although rare cases of MC breast cancer are reported as well. The prognosis varies depending on how far the cancer has progressed at the time it's diagnosed. Treatment for MCs of the salivary glands is similar to treatments for other salivary gland cancers.
Spindle-cell carcinoma is a specific type of squamous-cell cancer that starts as a localized disease. When it appears on the skin, it usually occurs in sun-damaged areas or in preexisting lesions, according to the Free Dictionary website. It can also occur in the bronchial airways of smokers. This disease derives its name from its characteristic rapidly growing spindle-shaped cells.
Melanoma is a cancer of pigment-producing cells in the skin. It's the most dangerous form of skin cancer. If caught early, the survival rate is high. If the disease has progressed further or spread to other organs by the time it's diagnosed, however, it becomes far more difficult to treat successfully. Surgery, chemotherapy, immunotherapy and sometimes radiotherapy are all treatments for level 5 melanoma.
Mucoepidermoid carcinomas (MECs) are a cancer of the salivary glands in your mouth and throat that produce saliva. Salivary gland cancers are fairly rare in the general population, although in older age, radiation exposure and workplace exposure to materials like silica dust are factors that potentially increase the risk of this cancer. The type of treatment doctors prescribe for this disease depends on how far it has progressed at the time of diagnosis.
Para-amino-benzoic acid, more commonly known as PABA, is a sun screen agent that is now shown to promote cancer in users. It functions by reflecting the ultra-violet rays of the sun and converting the energy from sunlight to heat. PABA has also been used as an oral supplement to help treat constipation, gastrointestinal disorders and to help reduce the symptoms of vitiligo, which is a loss of pigment in random spots on the skin.
Despite scientifically based facts, there are several myths circulating about acne's causes and treatments. Some may have some truth to them, but the explanation is often not relevant to what the true cause of your acne is. Misconceptions about acne should be corrected to provide the best acne treatment possible and to further prevent acne.
There are dozens of different types of cancers, but many of them share similar symptoms. If you suspect that you might have a form of cancer, it's important that you do a thorough self-exam to see if you've developed any new moles, strange lumps or other growths, particularly if your family has a history of one or more forms of cancer. But even if you have what appears to be evidence of disease, the one true way to find out for sure is through a medical diagnosis.
There are dozens of different skin irritations, flareups or possible diseases that may appear on your face. Many of the skin problems are relatively easy to diagnose simply by having your dermatologist look at the rash or skin in question. However, if your doctor is not immediately sure what the problem is, there are a few options available to diagnose the skin issue and correct the problem.
Superoxide dismutases (SODs) are a group of enzymes that are abundant in cells throughout the body. According to Superglisodin.com, superoxide dismutases inhibit the side-effects of cancer drugs. For example, SODs protect against radiation-induced cell death in humans. SOD enzymes play an important role in repairing cells that have been damaged by cancer. SODs reside both in the epidermis and the dermis of skin. They produce healthy cells called as fibroblasts. Healthy cell growth also stimulates the immune system.
