Combining nature and Greek mythology, researchers at the Technion (Israel Institute of Technology) have developed a “Trojan Horse” tiny to inject anticancer drugs directly to cancer cells. With this system, drugs are released only when they are inside them. Thus, there are no damage to healthy cells in the surrounding area.

Yoav Livney team created a system linking folic acid and an anticancer drug to an extract of larch, a tree abundant in the vast boreal forests of Russia and Canada.

Some cancer cells produce 10 to 100 times more folate receptors than healthy cells. These receptors capture folic acid, which is necessary for rapid growth and division of cancer cells. Therefore, the researchers used folic acid as bait for the selective attack against cancer cells. (more…)

According to new research, the chemical profile of the urine of children with autism is different from the non-autistic. This could allow a diagnosis of the disease before the manifestation of other signs of it in the child’s development.

The study’s authors, from Imperial College London and University of South Australia, suggest that the results of this research could end up making it possible for a simple urine test for determining whether a child has autism or not. (more…)

A new discovery made by the Institute Ragon (under the Massachusetts General Hospital), MIT and Harvard University, can affect the design of an effective vaccine against HIV.

When people are infected by HIV, AIDS often end up developing the full extent unless they follow a strict medication. However, a small number of people exposed to the virus develop AIDS very slowly, and some never develop. (more…)

For the first time worldwide, the xenon gas has been successfully delivered to a newborn baby in an attempt to avoid brain damage from lack of oxygen at birth. This pioneering technique has been developed by Professor Marianne Thoresen from Bristol University, and applied at the Hospital of St Michael.
Excluding cases of premature births every year many babies who otherwise would enjoy good health, die or suffer brain damage due to lack of oxygen and/or blood supply at birth. This can lead to life-long consequences such as cerebral palsy. In the United Kingdom, the annual number of births problem after nine months of pregnancy is more than 1,000.

The use of xenon gas to prevent brain injury was developed by Professor Thoresen with the help of Dr. John Dingley of the University of Swansea, United Kingdom. (more…)

It has been successful in finding a way to create functional hair cells of the inner ear in a Petri dish.

Deep in the ear, certain specialized cells called hair cells detect the vibrations in the air and translate them into sound. Ten years ago, Stefan Heller, a professor of otolaryngology at the School of Medicine, Stanford University, conceived the idea that if you could create these cells in the laboratory from stem cells, that would be of great help for scientists to know in detail the molecular basis of the ability to hear, and thus be better able to develop more effective treatments aids.

Munich – The world’s first time leading British doctors have heart surgery by remote control. Although there was a surgeon in the same building as the patient, however, he controlled the robot arm from another room. (more…)

The lifetime stability of the bones apparently decided early on after birth. How much calcium a baby the first days and weeks to include in, influences, such as bone marrow stem cells to form many. This resulted in a new study by the North Carolina State University, USA. The research team led by Dr. Chad Stahl believes that this development in the long term impact, such as the osteoporosis risk in later life. The results of the survey will be presented at the meeting “Experimental Biology 2010” in Anaheim. (more…)

A team of researchers funded by the U.S. National Space Biomedical Research Institute (NSBRI) has developed software that uses mathematical models to help astronauts and ground support personnel to better adapt to changing work shifts and sleep schedule. Outside of astronautics, the software may help people adapt to night work, shift work hours drastically or experience “jet lag” due to travel to a zone very different from yours.

Dr. Elizabeth Klerman, a professor in the School of Medicine, Harvard University is the head of the project. (more…)

In which it constitutes a great scientific advance, one has been able to increase of the spectacular form the volume of genetic information on complex human diseases and its possible treatments available for the investigators of the medical field.

The international team of scientists has made this important work, led by researchers at CCIA Pediatric Oncology Institute in Australia, the University of New South Wales in Australia, and Pennsylvania State University in the U.S., sequenced the genomes of various South African indigenous and, among other findings, has discovered that they are among those with higher genetic diversity in the world.

Women who have created the ass too big and too small chest could soon have an option to invert the equation. Fat cells are extracted from adipose tissue, then filtered using technology developed by Cytori Therapeutics, in order to increase the proportion of adipose stem cells and, finally, are injected into the breast. So far, the treatment, which is marketed in collaboration with GE Healthcare, has been used only in women who have lost a breast due to cancer, but they are about to begin tests with healthy women in the UK.
