New Clues for Treatment of Disease That Causes Accelerated Aging

...microscope, it leads to visible distortions in the structure of cell nuclei. By studying the mutations that killed the two infants, Miner and his colleagues acquired new perspective on the mutations in progeria. When they compared how much good and bad lamin A was being made in cells from progeria patients a...

Gluten Intolerance Cases Diagnosed Late in UK

...oup found in wheat and other flours that forms the structure of the bread dough. Gluten holds the carbon dioxide (CO2) produced by the yeast and expands during fermentation, and provides the elasticity and extensibility (stretch) in bread dough. Glutenin and gliadin are the two proteins that form gluten. Glu...

...acked and invaded, Fox says, to the point that the structure of the joint can be destroyed. This can lead to deformities and disabilities. Patients may develop inflammation in their lungs or peripheral nerves, inflammation in the salivary glands or tear glands that prevent them from functioning normally, and...

Tissue Engineered Scaffolding Allows Reproduction of Cartilage Tissue

...stics while synthesizing cartilage in the scaffold structure in vivo, notes study author Dr. Byoung-Hyun Min. Cell-derived scaffolding may hold great promise for the future. A variety of applications are possible for the engineering of cartilage tissue as the shape and porosity can be altered to suit the typ...

DNA Repair Proteins Monitored at Double-strand Break

Lawrence Rudel, Ph.D., a professor of comparative medicine, said that the study raised hope for humans. "We deleted an enzyme in mice and they could eat any type of fat and not get...

Targeting Sugar on Blood Vessels may Inhibit Cancer Growth

... enzyme is responsible for modifying the molecular structure of a sugar called heparan sulfate. In endothelial cells, this sugar facilitates the action of several important vascular growth factors that support angiogenesis. An antibody drug called Avastin, produced by Genentech, has been shown to block a maj...

Study Finds That Fruit Flies also Have Free Wills

...tations. The researchers found that the temporal structure of fly behavior is very different from random noise. The researchers then tested a plethora of increasingly complex random computer models, all of which failed to adequately model fly behavior. The team was able to analyse the fly's peculiar spont...
