Allergic disorders reduces the risk of cancer
Allergic disorders such as asthma or eczema, can improve the body's ability to remove malignant cells, say researchers. The fact that these diseases are associated with overactive immune system, the scientists write in the journal of the American College of Allergy, Asthma and Immunology (ACAAI). Thus, the above-mentioned diseases can reduce the risk of cancer.
Scientists conducted a study in Montreal (Quebec), wrote The Times of India. During the 7 years they have seen 3300 patients with cancer of men and a control group of 500 people.
Odds ratio were calculated for the relationship between asthma or eczema and over 20 types of cancer combined and for each of the 8 common cancers (stomach, colon, rectum, lung, prostate, bladder, skin and lymph nodes), separately.
"In our study, people with asthma had lower chances of getting stomach cancer, and in patients with eczema had a lower risk of lung cancer, compared with the other" - said Dr. Mariam Al-Zayn, one of the leading authors of the study.
"We can not fully explain how allergies can reduce the risk of cancer, but this study is promising. We hope that future studies continue to explore this connection and the role of the immune system in reducing the risk of developing cancer," - said researcher ACAII, MD Sciences, an allergist Bernstein.

The risk of pancreatic cancer depends on the waist
The risk of pancreatic cancer depends on the waist
The risk of cancer of the pancreas in obesity depends on where localized excess weight. For people who have dominated the fatty deposits in the abdominal area - especially women - the risk above.
This is the conclusion the authors of the study, whose results were published in the journal Archives of Internal Medicine "(Archives of Internal Medicine). In addition, the study confirmed that the risk of pancreatic cancer increases with body mass index (BMI).
Speculation on the relationship of obesity with the risk of pancreatic cancer were expressed earlier, but the findings were contradictory. To clarify them, Dr. Alan A. Arslan and his colleagues from the School of Medicine at New York University, analyzed data from 2,170 patients with pancreatic cancer and 2,209 healthy people participating in the project PanScan National Cancer Institute, USA. The project was launched in 2006 and is aimed at finding disease genes and the role of other factors, including lifestyle and environment.
For all study participants revealed a positive relation between BMI and the risk of pancreatic cancer: for a quarter of the subjects with the greatest risk of BMI was higher by 33% than that for the quarter with the lowest BMI. Moreover, for women who are overweight the risk was 31% higher for women with obesity - a 61% higher than for women with normal weight.
Increased ratio of waist circumference (WC) to hip circumference (OB) also increased the risk of pancreatic cancer, especially among women. For women with the highest ratio of ON to the risk increased by 87%.
"Complementing the data from previous studies, our results confirm the role of obesity in the development of pancreatic cancer", - said Dr. Arslan.
According to the American Society for the fight against cancer, the risk of pancreatic cancer for the average person is 1,4%.

Cocoa recognized as the best drink for recovery after sport
Cocoa recognized as the best drink for recovery after sport
American scientists have found that cold cocoa (chocolate milk) restores muscle after exercise faster than the special drinks designed for athletes, according to The Daily Telegraph. The results of the specialists James Madison University (James Madison University) were represented at the conference of the American College of Sports Medicine (American College of Sports Medicine).
Scientists have conducted four studies in which they compared the rate of recovery of muscles after prolonged physical exertion at the use of different drinks. Evaluating the data obtained, the researchers found that after eating cocoa muscle athletes recover more quickly than when using other fluids.
According to the authors of the study, cocoa contains necessary for the recovery of muscle protein and carbohydrates, which fill the energy supply of muscle tissue. In addition, the use of milk fills supply of water and various ions (potassium, calcium and magnesium), which are allocated sweat glands in physical activities.
Earlier, Australian researchers found that consumption of sweet coffee as well helps to restore muscle. Caffeine helps muscles to absorb glucose and significantly increases the rate of replenishment of glycogen in the muscles after heavy exercise. In addition, the results of other studies also suggest the usefulness of milk for athletes.

Regular consumption of yogurt protect children's teeth from caries
Regular consumption of yogurt protect children's teeth from caries
Regular consumption of yogurt may reduce the risk of dental caries in children, scientists say. Kids who eat dairy products for at least four times a week, complained of problems with their teeth for 22% less likely than those who did so less frequently than once a week, showed a study in Japan.
Experts Fukuoka University and the University of Tokyo examined more than two thousand children under the age of three years. They also interviewed parents, in order to know that children usually eat. Then the dentists assessed the health of teeth of each of the children. The results showed a clear link between the consumption of yogurt and a lower prevalence of caries, writes The Daily Mail.
At the same time, other similar products such as butter, cheese and milk, does not affect the state of the teeth. Scientists suggest that this is related to proteins that are found only in yoghurt. They "seal" the surface of the tooth enamel and protect it from exposure to harmful acids.
This study confirmed the results of the experiment carried out earlier by specialists from Australia. They studied the effect of yogurt on the teeth that were removed from patients. It turned out that yogurt protects teeth from decay. At the same time, dentists from the UK warned: some yogurts contain sugar, and therefore the risk of caries in their use may increase.

Canadian and Australian scientists develop new method to combat leukemia
Canadian and Australian scientists develop new method to combat leukemia
A new method for combating leukemia developing Canadian and Australian experts. They were able to create artificial antibodies that destroy the specific protein - C-D-123, part of the membranes cancerous stem cells.
This method may prove to be very promising, since the previous stage of research, this group of scientists has shown that cancerous stem cells are not amenable to chemotherapy. In addition, as reported by researchers in the latest issue of the journal Cell and Stem Cells ", new antibodies do not have a negative impact on" normal "blood cells.
From a Canadian research team led by Senior Research Fellow Cancer Institute, Ontario, John Dick, with an Australian - Adjunct Professor, Institute of Pediatric Oncology Richard Locke. Now, after the pilot phase, scientists are ready to test the effectiveness and safety of a new method in clinics.

WHO has endorsed a second vaccine against cervical cancer
WHO has endorsed a second vaccine against cervical cancer
World Health Organization (WHO) approved the drug for a second vaccination against cervical cancer, reports AP. Recommendations to the widespread use of the drug was "Cervarix", produced by GlaxoSmithKline.
This medicine is sold in 97 countries. Approval received from the WHO, indicates that the various UN agencies and charities will be able to begin formal delivery of the drug to vaccinate populations in developing countries.
Charitable Organization World Alliance for Vaccines and Immunization (GAVI) in the last year established a priority in the procurement of drugs for the vaccination of the population 73 poorest countries from cervical cancer. According to company representative Dan Thomas (Dan Thomas), first of all immunizations needed in those countries where the population is unable to undergo early diagnosis of disease.
The first vaccine against cervical cancer, approved by WHO, has become the drug "Gardasil" company Merck. According to representatives of the organization, the use of two drugs will help save tens of thousands of lives.
According to WHO, each year from cervical cancer kills about 280 thousand women. More than 80 percent of them are women living in developing countries.

New genes that influence blood pressure
Scientists have discovered several new genes that influence blood pressure
An international team of scientists from the U.S., the Netherlands and Iceland has discovered several new genes that influence blood pressure. According to a press release distributed by the National Institutes of Health in the U.S., it could open new avenues of research aimed at prevention and treatment of hypertension.
The press release states that the work was based on the basis of several large-scale medical projects, covering a total of observations over more than 29 thousand people. For comparison, used even larger database - to 34 thousand patients.
The result has been found "substantial relationship" with the level of arterial blood pressure of 11 genes: four - for systolic blood pressure, six - for diastolic and one - for hypertension. One of the leaders of the study, director of cardiology Framingemskogo project, Dr. Daniel Levy said that the key eight of these genes are still not part of whose short list of key suspects in the effects on blood pressure. "
The authors suggest that high blood pressure - a hereditary disease, but previous attempts to identify specific genes that are associated with it were only "partially successful". According to their data, in the whole world from cardiovascular and other diseases associated with abnormal blood pressure, die every year more than 7 million people. In the U.S. pressure increased roughly one in three adult residents of the country, ie approximately 72 million people.
