The use of beet juice helps reduce blood pressure
Use 500 ml of beetroot juice a day can reduce blood pressure. The effect is approximately one hour after taking the juice, and continues throughout the day, said the journal Hypertension.

British scientists from the Barts and The London School of Medicine and Dentistry conducted a study involving healthy volunteers who were asked to drink half a liter of beet juice. An hour after taking the juice of blood pressure among participants start to decline, scientists said. According to their figures, the maximum pressure (the upper - to 10.4 mm Hg and lower - at 8 mm Hg) were recorded in about 3 hours after consumption of juice, and the effect lasted for up to 24 hours.

According to the head of research Amrita Ahluwalia, the effect of beet juice is due to high levels of nitrate - a substance that is present also in a salad and spinach. Under the action of bacteria on the surface of language and into the saliva, nitrate, nitrite turns into. When swallowed nitrite and hit him in the acid environment of stomach, the substance turns into nitric oxide, or into the blood in the form of nitrite.

Time maximum concentration of nitrite in blood consistent with the greatest decline in blood pressure among volunteers, which confirms the role of the substance, researchers said. When you freeze the process of turning nitrate into nitrite (for this purpose on the surface of language volunteers caused anaerobic bacteria) the use of beet juice does not lead to lower blood pressure, which served as additional proof of the crucial role of nitrite.

According to statistics, hypertension suffered more than 25% of the adult population. Increased pressure is responsible for about 50% of coronary artery disease and 75% of strokes.

«Our study shows that consumption of beetroot juice or other vegetables rich in nitrate may be a simple way to maintain the health of the cardiovascular system and may also provide an additional method of combating high blood pressure», - said Ahluwalia.

In turn, Professor Graham McGregor (Graham McGregor) from the British Hypertension Society noted the need for longer-term studies involving patients suffering from hypertension.

Cancer is a leading cause of death worldwide. In 2005, it killed 7.6 million people. If you do not take decisive action, in the next ten years, the cancer uneset lives of 84 million people.

The World Health Organization (WHO) as early as 2006, took the initiative to reduce the number of cancer deaths by two percent annually.

Every year around the world registered 10 million new cases of cancer. WHO experts believe that the leading preventable cause of cancer is tobacco use.

They draw attention to the fact that 700 million children - half of the world’s children - breathe air, poisoning smokers father or mother or other surrounding people.

WHO called on parents to remember about the dangers of cigarette smoke on the health of children and ensure their childhood without tobacco.

WHO stresses that now well-known causes of cancer, which makes it possible to prevent at least one third of new cases.

There is also a technique that allows to identify the disease at an early stage and carry out effective treatment yet one third of cases. There are effective schemes relieve the pain and palliative care to all patients with cancer.

But all this knowledge does not always apply in practice. Many States do not include cancer prevention and control them to priority areas.

WHO encourages all nations of the world to take effective national cancer-control programs and use available resources for this purpose not only for treatment but also preventive measures, writes Cybersecurity.

The American lost nearly 260 kilograms only because of changing lifestyles
A resident of the U.S. state of Nebraska was able to lose weight by nearly 260 pounds without liposuction and operations to reduce the volume of the stomach, said channel KETV. According to the men to return to a normal weight, he helped vegetable diet and physical exercise.

68-year-old John Lapitz almost died as a result of obesity: a few years ago, his weight exceeded 320 kilograms. Feeding on mostly fast-fudom, Americans consumed a daily basis not less than 10 thousand kilocalories and barely left the house. The only people with whom he maintained contact, remained his sister-in-law, as well as a woman is delivered meals at home.

John Lapitz decided to change his life after being stopped placed in the shower. He decided to have fewer sandwiches and more vegetables, then began to perform regularly Walking: first from room to room, and then on the street. In the end, his itinerary has increased to 12 miles a day. In five years, enhanced training, he lost more than a quarter ton, and now his weight is about 65 kilograms.

The words of John Lapitz confirms his former physician, a member of Nebraska Medical Center, Robert Hollinz. «This is a very unusual case, however, aware of other people dropping large numbers only through changes in lifestyle», - he noted. According to him, the effectiveness of diets and exercise depends primarily on the strength of will the patient, so the case Lapitz can be a good example for other Americans.

The level of testosterone affects the risk of fractures due to osteoporosis

In accordance with the results of the study, the level of plasma testosterone impact on the risk of fractures due to osteoporosis. Aging is accompanied by a decrease in the concentration of circulating testosterone, which certainly adversely affect the quality of bone tissue.

However, according to the work of scientists at the risk of fractures can affect the concentration of low testosterone, regardless of age and bone mineral density. When monitoring 609 men over age 60 on average for 5.8 years (up to 13 years) found that the risk of fractures statistically significant increases in the population of men with low testosterone value (1.33). The main risk factors of fractures in addition to hormone levels were age, weight, bone mineral density, smoking, use of calcium and SSSG. However, after the distribution of patients on these risk factors, a lower concentration of testosterone independently associated with increased likelihood of fractures, especially hip (1.88) and other nevertebralnyh fractures (1.32). Thus, measuring testosterone in elderly men may provide additional clinical information regarding the likelihood of fractures, and this relationship does not depend on the patient’s age and bone mineral density.

Overcoming chronic pain syndrome
Research team of University of Zurich and the Higher Technical School (ETH) managed to activate hindering the pain receptors in the spinal cord Rights, which opens up new possibilities for treatment of chronic pain syndrome.

The man felt excruciating pain through anger, coming from receptors in the skin, muscles, joints and internal organs. Special nerve fibers transmit irritation from the periphery to the brain, where there is pain perceived by man. «Spinal cord is included in these processes specific filter pain», said Hans Ulrih Tsaylhofer, professor of the Institute of Pharmacology and Toxicology, University of Zurich and the Institute of Pharmaceutical Sciences of the Higher Technical School of Zurich. This prevents what is normal touching the skin of our perceived as pain.

Buffers the pain of spinal cord nerve cells emit transmitter called gamma acid (GABA). This is in contact with neighboring nerve cells, called synapses. Activates the transmitter in neighboring nerve cells Synchronous channels and thus hinders the activity of nerve cells conducting the pain signal to the brain.

People suffering from chronic inflammatory diseases such as rheumatoid arthritis, or amenable to traumatic damage nerve cells after the accident, the inhibitory effect of GABA heavily undervalued, then what pain signals directly into the brain.

In Switzerland, has developed a number of drugs that increase GABA function, thereby alleviating the suffering of the patient. But today the introduction of these drugs can be carried out exclusively by injection in the spinal cord. This procedure is quite dangerous, difficult and painful. According Swixmed, collaborating with research centers of Switzerland, for the development of oral drugs that act, the Swiss scientists need to undertake a number of experiments. To date, the effectiveness of the drugs proved only in experiments on animals. However, researchers have high expectations for interest and cooperation of pharmaceutical organizations to open new drugs to treat chronic pain syndrome.

Studies in recent years, performed in vivo and in vitro, showed that stem cells (MSC) have anti inflammation properties.

In this work, performed on mice officers Cardiovascular Research Institute, University of California, studied the effect of introducing MSK directly into the airspace of the lungs after 4 hours after the introduction of endotoxin Escherichia coli (5 mg / kg). Compared with the control group, survival MSK processed within 48 hours after exposure significantly increased (respectively 80% and 42%; p <0,01). In addition, the treatment MSK mice was observed decrease excess fluid in the lungs (a measure lung edema) - 145 + / - 50 against 87 + / - 20 mul; p <0.01; as well as reducing the concentration protein (a measure of alveolar epithelial and endothelial permeability) - 3.1 + / - 0.4 to 2.2 + / - 0.8 mg / ml; p <0.01. The test series of experiments instead of living imposed apoptirovavshie MSK MSK or living fibroblasts, but the protective effect was not reproduced.

Favourable impact MSK does not depend on the ability of cells integrated into the fabric of the lungs and was not connected with the cleanup of endotoxin through MSK. Introduction MSK reduces the inflammatory response to endotoxin (reducing the content TNF-α and MIP-2 in plasma and increasing the content of anti-cytokine IL-10). When combined with the cultivation of MSK alveolar macrophages found that does not depend on contact cells.

Results of the show that the introduction into the lungs mezenhimalnyh stem cells significantly reduces the severity of acute toxic lung lesions and increases survival.

Materials research presented in the article Gupta N, et al. Intrapulmonary delivery of bone marrow-derived mesenchymal stem cells improves survival and attenuates endotoxin-induced acute lung injury in mice. J Immunol. 2007 Aug 1; 179 (3) :1855-63.

Inclusion in the diet of cauliflower and broccoli reduces the risk of developing severe forms of prostate cancer, the Journal of the National Cancer Institute.

The study was conducted by specialists from the National Cancer Institute (USA) and the Canadian organization to combat cancer (Cancer Care Ontario).

The scientists analyzed the results of 1300 survey of men who have been diagnosed with prostate cancer.

It turned out that the frequent consumption of green vegetables, as well as representatives of cruciferous family - especially broccoli and cauliflower - led to a decline in the likelihood of severe forms of the disease prostate cancer. Weekly use cauliflower dishes from the risk of tumor is reduced by 52%, and when using the same amount of dishes from broccoli - by 45%.

Previous studies have shown that broccoli and cauliflower contain substances that have antitumor effect, but the relationship between consumption of these products and lower risk of severe prostate cancer detected for the first time, reported the head of research Victoria Kirsch (Victoria Kirsch). According to her, the diet with high content of broccoli and cauliflower may be offered as a measure of primary prevention of prostate cancer.

Prostate cancer - one of the most common cancer in men. Only in Britain are diagnosed each year 32 thousand new cases.
