What is genetics?
Genetics is the branch of medicine that deals with heredity, or the characteristics that we get from our parents and other ancestors. Certain characteristics, both favorable and unfavorable, are passed down from generation to generation through the code in our genes called deoxyribonucleic acid (DNA).
As with all diseases, it is important to determine whether RA is inherited. This would allow doctors to predict which family members would likely get RA based on the present genes.

Is RA inherited?
Rheumatoid arthritis is not a classically inherited disease, so we cannot predict who will get the disease. There is, however, an association- although a slight one-between a certain set of genes found on chromosome number 6, or the immune response chromosome, and those who get this chronic disease.

What Is HLA?
HLA stands for human lymphocyte antigens. These are molecules that are unique to each person and are found on the surface of one’s cells. This is how the body distinguishes self from non-self. HLA is also called the major histocompatibility complex (MHC).
Scientists have been looking for a genetic link to rheumatoid arthritis for years, and the obvious place to look was at the genes on the number 6 chromosome-the genes that control the immune response.

Cervical caps are one of the oldest methods used to prevent pregnancy. Early caps were made from beeswax, silver, or copper. The modern cervical cap has been available in Europe for several years and has been approved for use in the United States by the FDA since 1988.
The cervical cap is a small cup made of latex that is designed to fit snugly over the entire cervix. It must be fitted by a practitioner and is designed for use with contraceptive jelly or cream. It is somewhat more difficult to insert than a diaphragm because of its smaller size.
The cap keeps sperm out of the uterus. It is held in place by suction created during application. Insertion may take place anywhere up to two days prior to intercourse and the device must be left in place for six to eight hours after intercourse. The maximum length of time the cap can be left on the cervix is 48 hours. If removed and cleaned, it can be reinserted immediately. The cervical cap may offer protection against STIs but not HIV
Some women report unpleasant vaginal odors after use. Because the device can become dislodged during intercourse, placement must be checked frequently. It cannot be used during the menstrual period or for longer than 48 hours because of the risk of toxic shock syndrome.

The body does not register liquid calories the way it does solid food. Here is what researchers at Purdue University have noted regarding the body’s response to liquid calories. In the study, Dr. Richard Mattes instructed one group of individuals to eat 450 calories of jelly beans each day; the other group was told to consume 450 calories of liquid, such as fruit juice. Both groups were asked to write down their total daily intake from all food and liquid. At the end of the study, it was revealed that the jelly-bean group reduced the amount of food they generally ate on a daily basis by approximately 450 calories. Why? Because the body signaled that it did not require as many calories as before since it was getting 450 calories of jelly beans, which gave these individuals a feeling of fullness, or satiety.
The liquid-calorie group experienced exactly the opposite effect. While they consumed 450 additional liquid calories each, they continued to eat the same amount as before. The body registered the 450 liquid calories, but these calories, unlike those of solid foods, did not tip satiety levels; that is, they did not create within the individual a feeling of fullness. The researchers concluded that the human body does not register liquid calories to make us feel full.
If you eat an orange, then your body starts to feel full; if you drink a glass of orange juice, your body feels nothing and wants more to eat. This study has provided an important piece of information for weight-loss strategists: Americans drink too many “designer” coffees, sodas, juices, alcoholic beverages, and other liquid calories. You need to become aware of the impact of this behavior and lower the amount of liquid calories you consume.
Recent research indicates that as childhood obesity rises so does the consumption of soda. Drinking just one can of soda a day could lead to more than ten pounds of weight gain in one year. Adults and children need to reduce, if not eliminate, their soda consumption.
