Traumas like Sept. 11 make brains more reactive to fear

... to look at the effects of trauma on the brains of healthy people, it is published in the May issue of the journal Emotion. "These people appear to be doing okay, but they may, indeed, be having more sensitive responses to upsetting stimuli," said Elise Temple, a co-author and assistant professor of human ...

How to steer a moving cell

"This is the first time a group of researchers from several disciplines ?biologists, chemists, proteomics researchers and computational biologists who can integrate large data sets ?have applied a global approach to analyzing h...

Students invent protective pouch to enhance cell therapy

...ovide effective treatment without interfering with healthy body functions. Arepally and Bulte have overcome some of these hurdles by working with semi-permeable alginate microcapsules ?tiny spheres that surround the injected cells and protect them from the body’s immune system. At the same time, the sphe...

However, it can cause multi-organ disease in newborns or persons who are immuno-compromised such as organ transplant recipients or AIDS patients. Ware said, "The main importance of these experiments is identifying the critical molecu...

Scientists develope a new model of artificial canine skin

...ytes) and the dermis (fibroblasts) from samples of healthy dogs were used. The dermis cells, inserted into a collagen marix (a very common protein in skin and joints), were used as a support for the epidermis cells, which were grown on its surface and were kept in growth conditions exposed to air. The cells ...

Sleepless for science: Flies show link between sleep, immune system in Stanford study

...s and shorter periods of continuous sleep than did healthy flies. They basically just didn't sleep well, concluded the researchers. The researchers can't say for sure say whether a disruption of the brain's central clock, which is the area of the fly brain that exhibits circadian gene activity, was respon...

Decoding protein structures helps illuminate cause of diabetes

... Though scientists already have a good idea of the healthy "before" and dangerous "after" hIAPP structures, the steps in between remain somewhat of a mystery and may hold clues to what drives the transition, says UW-Madison chemistry professor Martin Zanni, who led the new study. In trying to understand d...

They will enable better understanding of the organization of normal brains, and could help researchers in identifying fine morphological and chemica...

Proteasome activator enhances survival of Huntington's disease neuronal model cells

...acellular systems work in concert to keep the cell healthy and from clogging up with damaged proteins. When proteins or peptides mutate, they can present major problems to the clearing up of the intracellular environment. In Huntington's disease (HD) the disease provoking mutation in the huntingtin gene even...

Leukemia drug turns mini-molecules up, cancer genes down

...The immature cells accumulate until they crowd out healthy white cells in the blood and bone marrow. "Our findings suggest that these three miRNAs help re-program the malignant cells to a more normal state," Garzon says, "and that they are also important for normal differentiation." In this study, th...
