Trial success for diabetic nerve therapy

...opathy and optimistically look forward to the next stage of development of this novel therapeutic when phase-two clinical trials start later this year." The incidence of diabetes, a condition in which the amount of glucose in the blood is too high, is increasing dramatically with the World Health Organisa...

The loss of a protein favors lung tumor growth

...o the fact that it is generally detected at a late stage when the disease is nearly incurable. Therefore it is necessary to develop new strategies that permit the detection of tumors of smaller size, biomarkers that make early detection possible, as well as a greater understanding of the alterations that o...

Mayo Clinic study finds two genes predict outcome for breast cancer patients

... novel genes within the tumors of women with early stage breast cancer may allow identification of women wh...ession levels of two genes within women with early stage breast cancer affected the outcomes of women with estrogen receptor-positive breast cancer. The res...

It's not fair! We are programmed to resist weight loss

...d a plateau. "There appears to be little at this stage to predict the onset, duration and frequency of the plateau," Dr King said. "My research now aims to identify and characterise mechanisms responsible for our inbuilt weight loss resistance." Dr King said our energy balance system was programmed t...

Mice lacking key immune component still control chronic viral infections

...r surfaces. MHC Class I molecules act as a kind of stage for this inspection process, binding to the protein parts as they are sent to the surface and allowing CD8 T cells to recognize the presence of a foreign invader. When the CD8 T cells recognize a viral protein part, they either destroy the cell displ...

New tool tracks brain development in babies

...van Pul said. "The detection of injury at an early stage is essential for the development of strategies to limit permanent brain damage and to improve prognosis." The researchers used 'diffusion tensor' magnetic resonance imaging (MRI), which depicts the diffusion, or displacement, of water molecules thro...

Research identifies protein in mice that regulates bone formation

Teasing out tissue from blood

...to revert a patient's blood cells to the stem cell stage and then chemically nudge them to re-specialise into particular tissue types that can be implanted to heal damaged tissue. A huge advantage over using donated tissue is that the transplant would be "autologous" ?made of the patient's own cells, thus ...

How IVF could be causing genetic errors in embryos

... these findings was unclear at present. "The next stage of our research is to examine further the effects of IVF and ICSI on the genetic make-up and the form and function of cells from mouse embryos. We want to understand why these techniques appear to be affecting the imprinting of these genes. We hope t...

How ancient whales lost their legs, got sleek and conquered the oceans

...l traces of hind limbs vanished at the end of this stage of whale evolution, said Cohn. A gene called Hand2, which normally functions as a switch to turn on Sonic hedgehog, was shown to be inactive in the hind limb buds of dolphins. Without it, limb development grinds to a halt. "By integrating data from ...

Fish virus in Northeast spreading to other fish species

...ical cell culture technique to perform the initial stage of the diagnostic testing. This technique can take two to four weeks to yield results. Cornell researchers are developing a molecular-based test for VHSV based on a specific gene sequence in the virus. Once available, the new technique will cut the ...

NHGRI announces latest sequencing targets

A dichotomy in migration patterns found for sea turtles in east Atlantic

...pically undergoes a shift from an oceanic juvenile stage to a shallow-water, coastal adult stage. But the new findings--obtained by newly-improved methods for satellite tracking of the adult turtles' geographical movements and diving patterns--show that the sexually mature adult population also includes oc...

Life and death in the hippocampus: what young neurons need to survive

...he newborn neurons withered and died at a specific stage of their maturation," explains Gage. " The NMDA receptor modulates synapse formation and determines what pattern of input activity new neurons receive, which in turn determines survival or death." Combining mouse genetics and gene transfer techniqu...

Study links high levels of nitric oxide to infertility and sperm DNA damage

...the fertile men," said Dr Amiri. "However, at this stage we were unable to find the cut-off point at which NO levels switched from having a positive effect to having a negative effect. "This study indicates that infertile men have higher levels of sperm DNA damage and NO concentration in their seminal pla...

Combined treatment extends life expectancy for lung cancer patients

...er. However, only one-third of patients with early stage lung cancer qualify for surgery because of other underlying medical conditions. Radiation therapy has long been used for inoperable lung cancer, and more recently, doctors have used radiofrequency ablation (RFA) and microwave ablation, processes that...

New flood-tolerant rice offers relief for world's poorest farmers

...extremely unpredictable and may occur atany growth stage of the rice crop. While rice is the only cereal crop that can withstand submergence atall, most rice varieties will die if fully submerged for too long.When the plant is covered with water, its oxygen and carbon dioxidesupplies are reduced, which i...

Allergy battle could be won in five years, says scientist

Neural stem cell gene plays crucial role in eye development

...etics. "Right now, we are only in the hypothetical stage of therapeutic application of this work, but we finally have the genetic tools to actually test our hypothesis." Other authors that contributed to the study are members of the UNC Neuroscience Center and department of genetics: Dr. Olena Taranova,...

The shape of life: research sheds light on how cells take shape

...y were responsible for the stripes. In the first stage of the process, the microtubules line up uniformly, like pickets in a fence. As the microtubules continue to grow, they clump together in bundles of 200 to 300. Then these bundles buckle. Valles and Tang believe that the buckling occurs because, as m...
