Researchers at the University of California, San Diego, the Medical University of South Carolina, the University of Cincinnati, and American Life Science Pharmaceuticals of San Diego have validated the protease cathepsin B (CatB) as a target for improving memory deficits and reducing the pathology of Alzheimer's disease (AD) in an animal model representative of most AD patients. The study has been published in the online edition of the Journal of Alzheimer's Disease. According to...

Curcumin, a substance extracted from turmeric, prolongs life and enhances activity of fruit flies with a nervous disorder similar to Alzheimers. The study conducted at Linköping University, indicates that it is the initial stages of fibril formation and fragments of the amyloid fibrils that are most toxic to neurons. Ina Caesar, as the lead author, has published the results of the study in the prestigious journal PLoS One. For several years curcumin has been studied as a...

Findings may settle scientific debate surrounding this chemical found in red wine and other foods National Institutes of Health researchers and their colleagues have identified how resveratrol, a naturally occurring chemical found in red wine and other plant products, may confer its health benefits. The authors present evidence that resveratrol does not directly activate sirtuin 1, a protein associated with aging. Rather, the authors found that resveratrol inhibits certain types of...

A team of researchers led by Michigan State University has discovered an overachieving plant enzyme that works both the day and night shifts. The discovery, featured in the current issue of Proceedings of the National Academies of Science, shows that plants evolved a new function for this enzyme by changing merely one of its protein building blocks. The enzyme, ATP synthase, usually works the day shift, serving as a key player in storing energy created through photosynthesis in the...

A new study unravels key signals that regulate protective and sometimes pathological inflammation of the skin. The research, published online on January 26th in the journal Immunity by Cell Press, identifies a "gatekeeper" that, when lost, can cause inflammatory skin disease in the absence of injury or infection. The findings may eventually lead to new treatment strategies for the more than 10% of people in the western world that suffer from inflammatory skin diseases. Although the skin...

Crippling a protein that allows cancer cells to grow when oxygen is scarce causes tumors to regress, according to a study published online on January 23 in the Journal of Experimental Medicine (http://www.jem.org). An enzyme called PKM2 (M2 isoform of pyruvate kinase) is ramped up in cancer cells, allowing them to generate energy in the harsh, low-oxygen environment found within tumors. Michael Goldberg and Phillip Sharp at the Massachusetts Institute of Technology now find that inhibiting...

New research published in BioMed Central's open access journal Cell & Bioscience is the first to show that left-handed Z-DNA, normally only found at sites where DNA is being copied, can also form on nucleosomes. The structure of DNA which provides the blueprint for life has famously been described as a double helix. To save space inside the nucleus, DNA is tightly wound around proteins to form nucleosomes which are then further wound and compacted into chromatin, which is further...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
