Each year the content of vitamins in products is declining

Food is not able to meet human needs for vitamins and trace elements, as the number of useful substances are gradually being reduced.

This conclusion is derived from data provided by the Ministry of Agriculture, under which over the past 30-40 years, vitamin A completely disappeared from beef and its contents in poultry meat has decreased by 70%. Critical - 85% - Reduce the number of calcium in kale, previously regarded as the main source of this element. More than 30% decreased the content of magnesium in the parsley and dill. Now, to get a daily dose of vitamins and trace elements in food, you must eat to 5-7 kilograms of various foods, which the body naturally does not. Therefore, without receiving vitamin-mineral complex, modern humans simply can not do. Only this can help him cope with the lack of useful substances in products, rising by scientists associated with the widespread depletion of soil, and that the crop now take off without waiting for his mature, that they will withstand long transportation.

The greatest damage from arterial hypertension occurs in developing countries

NZ scientists study shows that the greatest damage from the AG observed in developing countries.

Carlene Lawes (Clinical Trials Research Unit, University of Auckland, New Zealand) assess the damage that the disease associated with increased blood pressure caused worldwide in 2001.

High blood pressure resulted in 54% of strokes, 47; IBS, 75% AG and 25% of all other cardiovascular diseases.

Nearly 7.6 million (13.5%) deaths worldwide have been linked to high blood pressure. More than 80% of the damage of diseases related to high blood pressure seen in the low to middle-income defined by the World Bank.

And about half of the damage caused by hypertension occurs in people with the level of systolic pressure below 145 mm RT art.

This situation resulted from the different access to quality health care in developed and developing countries.

Diabetes will treat gastric electrical stimulation

U.S. scientists begin clinical trials for the device implanted gastric electrical stimulation to help diabetes type II to normalize levels of glucose in the blood. According to the developers, the new technique has already helped several diabetes normalize the metabolism and reduce the dosage of medicines.

Implantable device the size of a mobile phone is equipped with six electrodes: Two record of reducing muscle wall of the stomach after the meal, another four, after receiving a signal from the first group, affect the nerve fibers going from the stomach to the brain.

Originally it was anticipated that additional stimulation of the brain will lead to accelerated offensive sense of saturation, reducing the consumption of food and lose weight. However, as the first test, the effect was quite small. At the same time, the experiment led to other equally important result: for all subjects experienced a significant decrease in blood glucose. The new technique can be effective in the treatment of type two diabetes - diseases associated with the gradual loss of sensitivity to the hormone insulin, responsible for the assimilation of glucose cells.

According to lead author of the study, a University Vanderbilta of Dr. William Richards (William Richards), the causes of this unexpected effect is not yet clear. According to one version, additional stimulation of brain centers led to the normalization of metabolism and increase the number of glucose.

To participate in a new phase of the test are invited volunteers aged 18 to 70 years, suffering from diabetes type II, and with excess weight. According to the organizers of the study, installation implanta performed under general anesthesia and takes no more than an hour.

Many American teenagers in the future awaiting heart disease

According to recent studies obesity epidemic among American adolescents will lead to a doubling of heart disease and deaths from them as early as 2035. In their report, scientists argue that the situation that arose today, could lead to big problems in health care in the future doctors and traditional means of treatment will not be able to prevent this. The projected current young professionals in the 30-35 years old will often be ill, seek assistance from doctors to miss working days and, consequently, die sooner.

Simulation of this situation by using computer programs found that 30 to 40 percent of adolescents are now the problem of over weight will in future have a problem with the heart. A total number of cardiovascular disease in the U.S. by 2035 will increase by 16%. The total number of deaths to the same time increase by 19%.

According to the statistics now have a problem with the weight of more than about 9 million American teenagers. That percentage, three times more than in the seventies the twentieth century.

Allergy protects against cancer of the pancreas
Excessive activity of the immune system, leading to allergic diseases, prevents the development of pancreatic cancer, said International Journal of Cancer.

That is the conclusion reached by Canadian scientists from the hospital Mount Sinai (Ontario) on a study involving 654 people. Cases of cancer, pancreas, were selected from the registry cancers in Ontario. As controls were selected roughly equivalent group of healthy people.

After studying history allergological participants found that people suffering in some way allergic cases of pancreatic cancer at 57% less likely to those who have never ctradal allergies. This dependence is not observed in patients with asthma and was particularly strong among men, the researchers reported.

The relationship between allergic and some cancer researchers followed in the past, but its cause was still unknown. Nevertheless, the new data could be useful in studying the mechanisms involved in cancer development, in particular the possible role of the immune system, said head of research Eylet Apple (Ayelet Eppel).

Cancer of the pancreas is one of the major places among causes of death from cancer. Only in the United States are diagnosed each year about 30 thousand new cases and only 5% of patients can live more than 5 years after diagnosis.

Tea and coffee reduce the risk of kidney cancer
Lovers of tea and coffee sick kidney cancer slightly less often than those who consume these beverages in small quantities. These findings came American researchers who reviewed 13 long-term studies involving more than 770 thousand people.

According to the medical school at Harvard University, among people who daily drank an average of three or more cups of coffee volume of 240 milliliters, cancer of the kidneys was registered at 16 percent less often than those who drank coffee daily or less. Daily consumption of at least one cup of tea was associated with a 15 percent reduction in risk of cancer. Milk, soft drinks and juices are not provided on the incidence of no effect.

The beneficial effects of tea and coffee remained statistically significant after accounting kidney cancer risk factors as smoking, obesity and high blood pressure. Research data used by scientists, lasted from 7 to 20 years and covered a total of 530 thousand women and 244 thousand men.

According to the authors, antirakovye properties of tea and coffee may be linked to the ability of both drinks raise the sensitivity of body tissues to insulin. Elevated levels of this hormone is considered one of the risk factors for many types of cancer.

A report on the study published in the International Journal of Cancer.

U.S. scientists discovered a gene, which stops blocking the development of malignant tumors and starts the process of self-destruction. This method potentially could be used to treat liver cancer, blood and bones, believed experts from the Medical College at Stanford University.

The subject of research scientists became gene MYC, which is responsible for making the protein, which can stimulate cell division. Mutation of the gene leads to uncontrolled cell division and growth of tumors. The experiments conducted on mice suffering from cancer of the liver, blood or bone arising from the defective gene MYC. In order to “switch off” MYC gene, researchers have used antibiotics.

After having introduced the drug as mice, blocking the work of a gene, a tumor ceased to grow, diminishing in size and in some cases disappeared a few days after treatment, the researchers reported.

According to scientists, halting tumor growth was associated with the restoration of natural processes of apoptosis - a mechanism of programmed death of cells damaged. “Our study showed that when you turn off the important cancer gene, tumor cells” realized “, that they violated that led to the restoration of physiological programme programmed death”, - said study leader Dean Felsher (Dean Felsher).

The specialists-oncologists thought this work is very interesting, but noting that the shutdown MYC gene may not be effective in all cases. Although the CF gene MYC-quite often becomes a cause of cancer, there are tumors, which are independent from him, reported scientists from Cardiff University.

A detailed report on the results of the study was published in the journal Proceedings of the National Academy of Sciences.

Australian researchers led by Professor Lidia Moravska, director of the International Laboratory for Air Quality and Health, accidentally discovered that printers emit large quantities of tiny particles that can potentially negatively affect the respiratory organs, cardiovascular system and even cause cancer, said MEMBRANA.

Australian researchers led by Professor Lidia Moravska, director of the International Laboratory for Air Quality and Health, accidentally discovered that printers emit large quantities of tiny particles that can potentially negatively affect the respiratory organs, cardiovascular system and even cause cancer, said MEMBRANA.

The particles were recorded, when scientists tested the effectiveness of ventilation to protect employees from the office of air pollution on the example of a large office, surrounded by roads.

Understood that dirt falls from the street: “We really did not expect to find anything from domestic sources of pollution, but soon found that much more dangerous domestic sources of external,” - said Moravska.

When it turned out that printers produce any particles, the researchers studied 62 printers and 17 of them were recognized as “emitter.” And a printer particles produced in quantities comparable to “emission” of a cigarette emitting smoke. However, 37 printers were absolutely safe.

Scientists report that the largest number of particles produced printers when they zapravlen new cartridge with ink, and when used in printing a lot of ink.

The concentration of particles during working hours to five times higher than outside. According to Moravska, particles can get into the respiratory tract and then into the blood, and risks to the health of people sitting in the office she felt “very high”. In this connection, the researchers recommend that employers pay more attention to ventilation systems.

Meanwhile, further studies are needed because scientists do not yet know the chemical structure of particles and did not realize until the end, as they get into the air.
