Diet is not enough to lose weight

Concluded a scientific study conducted by researchers from the United States to follow a diet low in calories is not making enough to lose weight, and stressed the importance of exercise to achieve this. The study, recently published " American Journal of Physiology : Physiology Regulatory , Integrative and Comparative Law " to reduce daily calories may not be enough to stimulate the process of weight loss , due to the natural compensation mechanism that works to reduce the physical activity of the body , as a result of low amount of calories obtained by the individual.
The research team from the " University of Oregon Science and Health" conducted a study several years ago on the type of macaque monkeys , during which he was subjected monkeys to a high - fat diet .
After that the team committed these animals to a normal diet contains fewer calories than the previous diet , and by up to 30%. The research team monitor weights monkeys and determine the level of physical activity during the entire month.
The researcher from the university and a member of the study team " Eleanor Sullivan ," that what sparked surprise is the non-registration of a significant loss in weight end of the month when the monkeys , but it drew attention to the existence of " a significant change in the activity of monkeys, has begun normal levels of activity physically tired after time short start cutting calories . "
For its part, see a specialist in the field of neuroscience behavior of the university, " Judy Cameron ," said the study shows the existence of a natural mechanism in the body keeps the energy in response to a reduction in calories , pointing out that it is apparent that the body develops a strategy because of the volatility that gets in the quantities of food available of the object.
The researchers hope that the results help professionals in the medical field to provide advice to their patients, and affect the development of community-based interventions to fight the epidemic of childhood obesity , and lead to the design of programs, stresses the importance of the availability of factors of diet and exercise.

Discovery helps in the healing of wounds

A study of modern scientific information that may contribute to finding treatments help in the healing of wounds , after he pointed to the role of a type of immune cells to slow down the process of closing parts of the affected skin. Conducted research team - included specialists from Loyola University of America - study included laboratory experiments on mice in order to test the effect of immune cells - known as killer T cells , or cells ( NKT ) , which has important functions in the fight against cancer cells and virus-infected cells - the process of wound healing.

The results of the study, published in " Journal of Surgical Research " that the healing process has been slower in mice that possess cells ( NKT ) , compared with mice that were deprived of the production of these cells .

According to the results show that the killer T cells were moving towards wounds positions , and slow down the process of healing.

The team did not specify after how slow killer T cells (NKT) wound healing, but expressed his intention to conduct a study in the future , to assess the possibility of inhibition of these cells by the use of antibodies , in order to prevent it from slowing down the recovery process of the skin.

Examination reveals cancer early

Researchers have discovered a new way to examine the blood cells that spread cancer , in addition to the possibility of using this method to predict who Sieodh cancer after treatment. Chose a team of Harvard Medical School and Hospital, Massachusetts twenty men from prostate cancer to experience a test that can detect two hundred cancer cell spread by the amount of blood the size of a teaspoon taken from the patient's cancer.

The researchers discovered the presence of cancerous cells scattered low-grade in patients with tumors that have not spread, and in patients who are still of the prostate gland three months ago.

Said Najrat , who oversaw the study from Harvard " usually do not expect the presence of cancerous cells spread in these patients , but this test has given us a tremendous amount of information about the extent of their exposure to risk ."

And added Najrat - at a news conference at a meeting of the American Association for Cancer Research - that her team will follow patients to see whether the tumors returned to those who have cancer cells spread .

She said it would be important to follow the men to see their condition, and also added that the test may be useful for monitoring patients with the so-called targeted therapies that affect cancer cells with certain specific genetic mutations .

This test will have in the future of great importance where it will serve as a blood test to detect prostate cancer , in addition to tests " anti - prostate specific " you are looking for a protein secreted only by prostate cells and which can indicate cancer.

Prostate cancer is the most lethal men after lung cancer , but it is often slow - growing disease , and there is no confirmation of the doctors on who the men who have the most deadly types and are more likely to spread or return ?

Dust enhances immunity of children with asthma

Recommended scholars parents need to expose children to dust to enhance immunity their bodies against the crisis or asthma , and suggest sending them to the gardens or fields to achieve this. Has revealed a study that houses these days are characterized by clean and less than the proportion of dust that can be exposed children, advised experts to be sent children to kindergarten or schools that purchased them Companion animals dragging behind her in the gardens .

The British newspaper The Daily Telegraph that the fields and gardens that will expose children to dust and other materials allergens , thus contributing to the increase in their ability to resist harmful bacteria.

The newspaper pointed out that cats and dogs in the House that would raise dust and thus help the children cope with the causes of the crisis or asthma.

Clean Cities

The researchers found that children living in the fields, they play less susceptible to crisis pectoris or asthma, compared with children who live in the cities clean .

And increased the proportion of allergic diseases - including asthma - in Britain over the past thirty years , until I got to three times the rates known in some parts of the country .

The head of the research team that conducted by the American Society of microorganisms Professor Raina Meir exposing children to dust tends to strengthen the immune systems in their bodies.

Meir added that the incidence of the crisis seriously increased over the past decade and that the reason for this is due to the lack of children's exposure to environments contaminated by dust containing microorganisms .

She pointed out that the fields and some care centers contribute to the prevention of the crisis in light of the exposure of children to an environment contaminated with germs by more , and clean environments in homes would increase children's exposure to allergic disease .

Dust samples

The study examined samples of dust collected from some of the houses and revealed that the percentage of bacteria are affected in the case of dogs or cats in the home or whether the children are sent to day care centers.

And detection research, published in the April / April 2010 issue of the journal " Applied Environmental Microbiology " about the need for a ratio of dust that contains bacteria in the house , and that percentage are affected by the presence of certain types of pets.

A new method for the treatment of leukemia

A team from the Faculty of Medicine, First University Hospital in the Czech capital Prague in the application of a new method in the treatment of certain types of leukemia each year more than two thousand Czech die without treatment , giving new hope to patients. Said head of the Institute of blood transfusion and diseases physician Marek Trnini - Czech , one of the scientists who participated in the development of the new mechanism for treatment - that certain types of blood cancers multiple has responded with the new method , which relied on a type of medicine called " monoclonal antibody " .

He explained that this medicine contains anti have an effective impact on the composition of the blood and responsiveness , and said it is working to reduce the activity of the cancer , making the patient feel better , and makes the percentage of survival longer period of not less than five years.

And adds Trnini in an interview for the island revealed that this drug with the new method is given to the patient that the treatment is associated with known chemical hearings .

He said that the result is a five - year patient survival is not interspersed with any serious life - threatening , the application of the patient's complete program of treatment without errors during the first phase of treatment of cancer of the lymph glands most common chronic types of blood cancers in Europe.

And operates the article " monoclonal antibody " to disrupt the cancer cells without damaging of all cells , a substance that has no side effects and symptoms of the patient 's life .

In describing the disease, says Trnini he suddenly appears in the form of an enlarged spleen , and watched the patient some lymph nodes in the neck , under the armpits , in addition to the signal analysis to a decrease in platelets with the stages of disease progression .

Reduction of immune

The condition causes the reduction of the immune system because of cancer cells destroys the lymphocyte natural , leading to inflammatory bacterial frequent and significant inflation in the lymph puts pressure on the veins and arteries, and in some cases some of the internal organs such as the bile duct , which leads to clogged and causing disease jaundice.

And advised Trnini - in order to detect the disease in its early stages - to conduct periodic checks of blood for those who are over forty times each year , and those who are over fifty - fifth session once every six months.

The Trnini indicates that he had discussed with doctors - in the conference , which was held recently in Prague and attended by doctors from 45 countries specialize in cancer - stages of a new treatment for cancer of the lymph glands chronic .

He said they agreed to exchange information in research for the development of subsequent steps for the development of therapeutic methods eliminate this type of cancer once and for all .

Ten years to decipher the genetic code of man

There are provoking research scientists beliefs prevailing in their time , the American biochemist Craig Venter , one of those. 10 years ago , has succeeded in decoding the genetic code for triggering a revolution in human genetics, and now wants the design of artificial objects .

The sixth of April / May 2000 , announced the American biochemist Craig Venter Craig Venter for his success in the identification of most of the constituent genes of the human genome . Today, hardly a month goes by without being read or hear about the success of scientists in decoding the genetic code of one of the objects or plants. During this week confirmed an international team of scientists, there are more than 800 gene responsible for Twitter 's goldfinch scheme (zebra finch) known as the beauty of his voice after their success in breaking the code of genetic . Credit for these successes due in part to the biochemist American Craig Venter , who entered in competition with scientists funded by the state , while the foundations of the company " Celera Genomics " in 1998 to announce two years after all his success in identifying most of the component parts of the human genome.

Self-made does not care to talk of others

Craig Venter , describes himself as someone who does not care never to others ' comments are not allowed to influence it. He adds that the same strain in the search for information to form an opinion of its own . Began his scientific career as a researcher in the project official U.S. to study the human genome, but the modus operandi of his colleagues did not like him , and even today does not hesitate to criticize them and say , in this context , " There are people who believe that they sealed all the sciences after graduation from the university , and they know what they want and they change their convictions never . But I 'm still looking for what I want to do . "

In 1998, Venter decided to break away from his teammates and set up a company of his own goal decipher the genetic code of a human being. He attributed his move such that his colleagues were working slowly tortoise " If you are able to adapt to continued to work just like any other colleagues, and we would even today to decipher the genetic code of man ."

Research provoke religious beliefs

Craig Venter , aged three and sixty -year-old seeks to serve humanity through his research , and some say it mimics the process of creation , but he says, "Some may consider my research a form of science fiction ," but he was confident that the design theory / Design , which believes in the theory of " Special genetic selection " Sthlan one day replace the theory of evolution developed by Darwin.

Venter does not care about the religious and moral standards , where he believed that man soon will be able to design artificial organisms . And actually he offered Venter in 2007, the first artificial bacteria " designed " by himself. It seeks through these bacteria to find a solution to the problem of energy in the world and to stop climate change . Venter and reflects the world believed the possibility of " solving the problem of synthetic fuel with the help of bacteria . Instead of extracting coal from the ground, the bacteria can be turned artificial sunlight to energy. " It also believes the possibility of " design " bacteria capable of absorbing carbon dioxide from the air and the other is able to produce large amounts of methane gas.

Hassle parents cause headache children

Suffering child out of every three in Germany because of repeated headaches bickering and family quarrels.

According to a study published in the journal Deutsche Erziblatt International that boys find themselves the center of a family dispute once at least a week, and this increases their risk of headache also more than once during the same period.

It also increases the family quarreling and bickering likely to be infected girls headaches by up to 25%.

And collected the researcher Jennifer Gassmann of the University of Gotngjin and colleagues in Germany About about two thousand people participated in the study during the period between 2003 and 2006, as it was found that between 10 and 30% of children around the world suffer from symptoms of headaches once at least weekly.

Healthy Eating saves kidney

The researchers said a lot of fruits and vegetables, nuts, and the reduction of food containing salt, red meat and ready-made ​​meals and sugary soft drinks, reduces a significant risk of kidney disease.

He received Dr. Eric Taylor and his colleagues at the Hospital women in Braigam to the results of the three studies and follow-up after the health status of 45 821 men for 18 years.

Show for those that who follow a diet to prevent high blood pressure and ate a large amount of fruits and vegetables, nuts, legumes and dairy products low-fat and whole wheat bread is milled, and played down the food salty and beverages high sugar and takeaway foods high calcium, potassium, magnesium, vitamin C and sodium, the less likely infected stones kidney rate ranging between 40% and 45% compared to their counterparts who ate different foods.

The researchers concluded that the nature of the diet affect high blood pressure and the risk of diabetes and other chronic diseases associated with kidney stones.

Smokers are more susceptible to TB

Taiwanese study found that smokers are more than twice as likely to symptoms of active TB disease compared with persons who have never smoked , prompting calls for policymakers to be tougher on smoking .

The study followed nearly 18 thousand people in Taiwan representing the general population for more than three years.

There is one out of every three people in the world infected with TB but 90% of these infections remain latent . The remaining 10 % Faisabon at some stage of their lives with active TB due to a weakened immune system .

For example, many infected people who have HIV ( AIDS) , tuberculosis and dying .

The study appeared in the previous Taiwan's 57 active cases of tuberculosis after a poll of 17 thousand and 699 cases , including three thousand and 893 smokers and 552 former smokers and 13 thousand and 245 never smoked .

The study found that current smokers more susceptible to active TB after taking into consideration gender, age, living in a crowded home , household income , marital status, alcohol use and employment.

The study pointed out that smokers may decrease their ability to fight viruses and bacteria such as tuberculosis in the lungs.

It is noteworthy that tuberculosis remains a leading cause of death in the world. 9.3 million were injured TB and 1.8 million died due to illness in 2013.

The World Health Organization ( WHO ) aims to reduce the incidence of tuberculosis to one case per million people per year by 2050.
