Microscope, researchers said a new high-capacity allowed the scientists to see a fish Alzerd during growth of one cell to the beating heart of Jenin, the first time become possible in vertebrates.
 

They said they had to rebuild a digital three-dimensional views of small fish during their growth, which could give an idea of how to form human organs and lead to a better understanding of the genetic roots of some diseases.

He said Joaquim Vitbroodt, who led the study when he worked at the European Molecular Biology Laboratory in Heidelberg, Germany, "This is such as the ability to see the animal life during the broadcast."

"We have a mass of cells which turn into a vibrant heart of Jenin, and you watch."

He said scientists have already done so in the not-organisms such as worms and backbone, which has only a few hundred cells, but so far the follow-up this process in vertebrates Ojntha, which consists of tens of thousands of cells was impossible.

The German team overcome this obstacle microscope developed strong enough to follow up tens of thousands of cells at the same time without the need for this kind of energy that could destroy or harm the fetus.

The Vitbroodt microscope that examines what they call the fetus through the optical chip in different directions, allowing the computer time making three-dimensional image of the passage of time will be integrated vision for growth.

He Vitbroodt who is now working Heidelberg University in Germany that "strength lies in the volume and clarity of the picture with tenderness at the same time the fetus and high speed is what is required to track moving objects."

"It's like a large puzzle and we can see parts of Independent. We see everything."

Alzerd and fish, also known as the "Zebra Danio" is a common subject of research because of cheaper Alvirat in farmed and shared in a number of biological characteristics with humans.

In order to the evolution of complex living organism, the embryo cells should be divided and moving around the body and arrange themselves in the form of complex and specialized tissues. So far, researchers say they have identified some differences in the movement of these cells than previously believed.

They say that the microscope can also be used in the study of mice, chickens and frogs.

Vitbroodt said that such tests could eventually provide a better understanding of how and why the proliferation of tumor cells in the body, sometimes against auto-immune diseases such as arthritis.

"There are many applications in respect of the human being .. this is just a starting point."

A team of French doctors to destroy cancerous cells spread in the brain by using lasers at the same time, nuclear magnetic resonance device without opening the skull.


"Dr." Alexander Carbontier "who heads the team of doctors specializing in the former world's nerve surgery, that it is the first time that the use of laser technology through the introduction of the cerebral cortex using a completely closed at the same time, nuclear magnetic resonance device to avoid any collateral damage.

Carbontier He added that patients were suffering from the spread of cancer in the brain, which moved him most of the other lung, breast and become more resistant to chemotherapy and means of radiation, which can not be subject to the condition of anesthesia.

The doctor confirmed that the results without any complications such as epilepsy or a Rain In six cases of full recovery from cancer, the disease did not appear again in the fifth since nine months on average, which was held surgery under topical anesthetic through a hole in the head cranium was introduced 3 mm Enter through a laser.

Researchers said Tuesday that millions of poor children in the United States may suffer from obesity before the age of ten result of the tensions faced by mothers and children, which are paid to seek refuge in the comfortable unhealthy food.

Said Craig Gandrsen from the University of Illinois, who led the study that the tension inherent in poverty and can comes as a result of financial problems and the burden of work and inadequate health insurance and other factors.

And continued in a telephone interview, "People eat in response to a sense of tension," adding that in this case, children may eat more responsive to the problems of tension in the house.

The results show that there is a need for a stable social safety net for poor families provide guarantees of protection, such as receipts for food and awareness of financial help people better manage their money better in addition to adequate health insurance.

Gandrsen screening and his colleagues at the Universities of Iowa and Michigan data 841 children living in families below the poverty line and those who were part of a nutrition survey between 1999 and 2002.

The research team said in the study, published in the month of September, the number of the magazine "Bedeatricks" or "pediatric" and "we found that the accumulated tensions in the troubled mother an important factor in increasing the weight of the child".

They added that children in homes where the volatile food many more prone to excess weight or obesity of children living in the tense circumstances where scarce food.

They concluded that, given that the majority of American children do not live in conditions of scarce food, the tension mothers "may be an important factor for the children of the United States who are overweight or obese."

The researchers wrote, "Our results related to the particular children between the age of three and X" can be for the older children to find refuge outside the home through friends or work.

It is estimated that 17 percent of American children between the ages of two and 19 years suffer from obesity and 16 percent more excess weight.

U.S. scientists said they succeeded in laying a very small hair cells in the inner ear Halzonp of laboratory mouse that may help restore hearing to deaf.
 


The Assistant Oorign Professor at the University of Health Sciences and John Bregnad the belief that "one of approaches to the restoration of the noise is to replace cells damaged another healthy and new."

The Bregnad "showed the work we have done that hair cells can produce audio in the middle ear at the snail mammals."

He and his colleagues Bregnad they were called gene genetic background to the authorized Atoh 1 in the internal development stage of the laboratory mouse, adding, "It is not known yet whether the gene transfer to the mouse ears will help to produce healthy cells, a hearing aid."

"In any case, the important step in the direction of approach could help determine the therapeutic intervention in order to help restore hearing to deaf."

Nutrition Specialist, said if the deal with American children healthy foods that contain all the nutrients that will help them focus during the study.
 


And advises the American worker Catherine Krause parents the choice of food, health food and adherence to a balanced diet that helps transmitters of the brain chemical "neurotransmitters" to work effectively and to stimulate memory and stronger focus.

Kraus said the site Hlt Dai News that "childhood is a very important step because it is the period in which it breeds is the body and brain, it is necessary to provide the body with food to help feed and educate children at an early stage of good eating habits," calling on parents in order to be "good examples for their children."

Krause asked parents to encourage their children to eat a healthy breakfast in the morning, pointing out that children who do not back the level of academic performance compared to others.

It also invited the children to deal with food containing natural fiber and reduce the saturated fat or inside the large amount of sugar, and avoid soft drinks and regular exercise
