Anxiety attacks and its treatment is being talked about in our community

Hi there, more about anxiety treatment and anxiety disorder here.

How A Stressful Life Can Contribute To The Development Of Alzheimer's Disease
Research about to published in the journal Molecular Psychiatry, resulting from a collaboration between scientists in Germany, Portugal and the UK, suggests that stress contribute directly to the development of Alzheimer's disease (AD). According to the results now published, stress induces the production of amyloid beta (A) peptide the molecule associated with the neural plaques characteristic of the disease and also makes neurons more vulnerable to A toxicity.

Bacteria Shed Light On An Important Group Of Human Proteins
Scientists have determined at very high resolution the first X-ray crystal structure of a Rhesus protein. This offers important insights into how these proteins facilitate the movement of ammonium across cell membranes. It also gives new information about the likely structure of these clinically important proteins in humans. (Read More)

New South Florida Nursery To Focus On Staghorn Corals
In response to the need for efforts to protect and recover surviving populations of the threatened staghorn coral, marine biologists have established an underwater nursery dedicated to the propagation of staghorn corals. The nursery will provide an opportunity to learn about growth and survivorship patterns, as well as how to stabilize corals damaged by natural disturbances or human activity. (Read More)

Stressed-out Skin Loses Its Antimicrobial Defense Mechanism
It is well known that being stressed increases our susceptibility to infections by impairing the function of our immune system, but the molecular links between stress and diminished immune function have not been determined. A new study in mice has provided insight into this issue by showing that psychological stress increased production of glucocorticoids and that this decreased the expression of antimicrobial peptides in the skin, making the mice more susceptible to skin infections.
