Adipose tissue surrounding the prostate gland of men with obesity, creates favorable conditions for the progression of prostate cancer.

What is the prostate gland
The prostate gland - is musculo-glandular organ located below the bladder and surrounding the initial portion of the urethra. The main function of the prostate is to produce secretions, which is part of semen. Ducts of the prostate glands open into the urethra.

Prostate cancer
In the early stages of prostate cancer does not manifest itself. Complaints are associated with tumor spread and metastasis. At the stage the only manifestation of the lack of symptoms, allowing the disease to suspect, is to increase blood levels of prostate specific antigen (PSA). As prevention of prostate cancer for all men should conduct an annual PSA test beginning at age 45.

By increasing the size of the tumor shows the following symptoms:
  • Frequent urination
  • Difficulty urinating
  • Urinary incontinence
  • urge to urinate.
The essence of the study

Scientists have received samples of adipose tissue surrounding the prostate gland in men with benign prostatic hyperplasia, prostate cancer and prostate cancer. Regardless of prostate disease in men with obesity , there is increased activity of genes in fat cells. These genes encode proteins involved in the immune response, inflammation, growth, reproduction, and cell death.

Increase in the activity of genes leads to inhibition of the immune response and stimulates the formation of new blood vessels, which creates favorable conditions for the progression of prostate cancer. The study's authors hope that the findings will more carefully selected treatments for patients with obesity.

Steaming cup of coffee or tea in the morning not only cheer you, but stand on guard your liver!

A team of researchers from Duke University (North Carolina, USA) concluded that caffeine reduces the risk of fatty liver (hepatic "obesity") in patients with non-alcoholic liver disease.

According to statistics, 70% of people suffering from diabetes and obesity , eventually become "happy" owners of steatosis. Unfortunately, the radical cure of the disease does not exist, even though it may provide some degree of control with diet and exercise.

The research team led by Dr. Ian Paul and Rohit Sinha, conducted their experiments on cell cultures and laboratory animals. It turned out that increasing the proportion of caffeine in the diet past contributed to the accelerated metabolism of fat in the liver cells. The authors concluded that the people in order to achieve the above effect should drink four cups of tea or coffee a day.

"We have become true pioneers in this area: to have no details have not studied the effect of caffeine on fat metabolism in the liver. "Tea and coffee is so firmly established in our daily lives that the opening of any useful properties of these drinks is very good news, especially given the prevailing among the people regarding their stigmatization."

The authors hope that guided their research, pharmacologists will begin to develop drugs based on caffeine, which would be devoid of the typical side effects of the latter, but would maintain a positive effect on the liver.

Moreover, in the long term this could become the foundation for a whole stratum of scientific research devoted to the potential therapeutic use of caffeine. Results of this study were published in the journal Hepatology.

American researchers have found that each person has a nose specific detector fat. With it, we can determine the level of this substance in different products.

Scientists at the California Science Center have found another way to avoid overeating, which can be used along with counting calories and a careful selection of products. It turns out that the person in the nose has its own excellent for detection of fat smell given to us by nature. Researchers believe that people can easily incorporate this detector for the regulation of its power.

Scientists believed that the smell of food is almost always determined by the man before he eats anything. It turned out that one of the first components of this odor is received by us olfactory information about whether the food contains fat. And if using innovative technologies, food producers will smell of fat in food more perceptible for the health of society, it will lead to a significant roll in the general trend of development of a worldwide epidemic of obesity .

"Our sense of smell allows us to significantly better orientation in everyday life than we used to think - said study author Dr. Johan. - We have the ability to determine the difference in fat content in the diet, which means that this ability provides specifically for evolution, and it is important. From time immemorial, the fat has been source of energy in the human body, and we learned to recognize the smell of greasy food to get this energy. Similarly, the sweet taste of foods high in carbohydrates is a sign that we obtain the energy of carbohydrates. "

Fast food is not the main reason for the spread of child obesity . This was stated by U.S. researchers.

They believe that children addicted to such food - a side effect of bad eating habits.

The experiment was conducted by researchers from the University of North Carolina at one of the schools in the U.S.. He showed that many children from an early age parents or caregivers instill the wrong template power which is based on processed foods and sweetened beverages. That is why such children are more likely to be overweight and eating a fast food meal.

Thus, fast food structure is part of their diet. Not the products themselves, and bad habits are to blame for the occurrence of child obesity. This is a much more serious problem, say the authors of the study.

Scientists have studied the effect of protein nesfatin-1, which contains a high concentration in the brain.

Staff at New York University decided to create a technique that allows to control diabetes and obesity through appetite and blood sugar.

Scientists have studied the effect of protein nesfatin-1, which contains a high concentration in the brain. Experiment has shown that when mice were given this protein, they consume less food eaten although often they occur faster oxidation of fatty acids and generally animals became more active. Plus, nesfatin-1 activated insulin secretion. All this might give weight loss.

Adjunct Professor Surai Unnippan told that this protein was discovered by Japanese experts in 2006. Initially it was attributed to the function control of appetite and fat production. Now, however, been proved that it affects more insulin secretion in pancreatic islets of Langerhans. That is, there is a direct and complex relationship between the brain and the gut.
