, Many women crave, desire to have large breasts because they are more sexy. Yet according to the study, a small women’s breasts are even more sensitive to touch, making it more able to give sexual pleasure.
In a study conducted at the University of Vienna in Austrian researchers found that large breasts 24 percent less sensitive than small-sized breasts.
“It’s because of the small breasts of the nerve that transmits the sensation of the nipple is more stretched,” said Alan Matarasso, MD, a plastic surgeon in New York City , as reported by Menshealth , Thursday (11/10/2011).
In addition, large breasts have more glandular tissue than fat tissue, which is the most sensitive part of the the breast.
“With small breasts, glands easier to be stimulated during foreplay for not being far below the layer of fat,” explains sexologist Rachael Ross, MD, PhD.
Not only is more sensitive, small-breasted women also tend to be healthier. This is because small breasts make it easier for women to detect breast cancer early symptoms, so that if cancer is found early can be treated.
“In Realize (breast self-examination, for the detection of breast cancer), it is easier to detect lumps at the back of the breast when a small size, because the layer through which a little more, “explains Dr. Marisa Weiss, oncologist and founder of breastcancer.org.
Dr. Weiss also said that small breasted women have better posture either because of pressure on the front of the body is not too big.
“bigger breasts naturally heavier and puts pressure on the body. This changed the posture of a woman so that the neck tension and are more likely to experience headaches,” Dr. Weiss said.
female breasts are very complex structures. In addition consists of fat and connective tissue, breast milk also contains channels, blood vessels, lymph nodes and the structure known as the lobes and lobules.
Each breast has 12 to 20 parts of lobules (milk-producing glands in the end of the lobe) and duct (milk ducts). Toward the nipple, each duct widens to form a sac (ampulla).

, The appearance of wrinkles, muscle weakness and cataracts can be delayed or even eliminated in the experimental mice. How to remove or kill the old cells that have stopped dividing. This technique is also being developed for the manufacture of anti-parent.
If these medications have been successfully created many believed would attract the attention of many people. Even the drug could become the biggest-selling drug.
Although these findings are still preliminary findings and new tested on lab rats, but these studies are expected to become the embryo of the discovery of anti-aging medicine in the future.
The number of cells that have stopped dividing elderly will increasingly piled up naturally with age. The scientists believe that these findings will be useful for the treatment of the elderly.
Experts say the findings are interesting, but still must be applied with extreme caution. The results of these studies have been published in Nature.
The study focuses on what is known as senescent cells. These cells to stop dividing into new cells and has an important role in preventing tumor development.
The cells are eliminated by the immune system, but the number of cells is more and more as we get older. Researchers estimate about 10 percent of the cells in the elderly is the senescent cells.
Scientists from the Mayo Clinic in the United States have found a way to kill or get rid of all senescent cells in experimental mice engineered to genetically. The mice will be more rapid aging than usual.
When the rats given the drug, senescent cells will die. The researchers looked at the three symptoms of old age, namely:
- formation of cataracts in the eyes
- loss of fat deposits under the skin
The weakening of muscle tissue
As reported by the BBCNewsHealth , on Thursday (3/11/2011), the researchers say the onset of the symptoms of aging can be delayed significantly when the rats were given the study drug.
The drug is administered after the rat met the criteria of age, so there is an increase in muscle function. One researcher Dr. Jan van Deursen said it was shocked by the very significant effect.
Treatment had no effect on the age, but it is probably because the type of mice used in the study were genetically engineered mice. The study is very interesting for many people because it can slow the signs of aging in humans. However, senescent cells can not simply be removed entirely from the man.
“I am very optimistic that the drug actually can have significant positive effects. In fact, every person who is still young enough to have killed or get rid of senescent cells them, because it is the body’s natural mechanisms. If someone can give priority to the immune system, or boost the immune system although a bit. This can cause the removal mechanism of senescent cells. Or, to develop drugs that target senescent cells, “said Dr.. Deursen.
While Dr Jesus Gil from the Medical Research Council’s clinical science center, said the findings should be applied with caution because there are preliminary findings. Certainly more research is needed to confirm and support the findings.
“But penelitin is an interesting study. Because based on these findings mean to get rid of senescent cells, it can improve the physical properties (phenotypes) associated with aging and improve the quality of life in older people, “said Dr. Gil.

, Complications of diabetes is not the only risks involved when a person’s blood sugar is controlled. When someone is diagnosed with diabetes, then that person is also more susceptible to infections Tuberculosis (TB).
The increased risk of TB infection in people with diabetes is quite significant, reaching 300 percent compared to the risk in healthy people. This fact mencadi threat in itself, given the number of persons with diabetes from time to time tends to increase rapidly.
“The growth of diabetes cases very rapidly is a challenge in combating tuberculosis,” said Dr. Anthony Harries, health experts from the International Union Against Tuberculosis and Lung Disease as quoted from Health24 , Thursday (27/10/2011).
At first glance these two diseases are not interrelated, because TB is an infectious disease, while diabetes is a metabolic disorder that can not be transmitted. Dr Harries acknowledges not yet know the mechanism is for sure, but there is some speculation that could explain it.
One of them mentioned that diabetes is directly or indirectly can make the immune system or immune menlemah. As a result, easy to attack a variety of infections including TB bacteria that is spread by droplets or patches of phlegm.
In addition to increasing the risk of contracting tuberculosis, diabetes menkjadi also its own problems in an effort to early detection of tuberculosis infection. In persons with diabetes, TB infection is often misdiagnosed as pneumonia mistaken so as not handled properly.
Generally, TB infection in the lungs occur starting from the top. While in persons with diabetes, TB infection is more common in the bottom of the lungs making it difficult to be detected and sometimes just plain given the drug because of mistaken for pneumonia.
The relationship between tuberculosis with diabetes was revealed Dr Harries in 42nd Union World Conference on Lung Health that is currently taking place in Lille, France.
