Walnuts prevent heart disease

A new clinical study shows that substituting walnuts for monounsaturated fat in a Mediterranean diet improves, and even restores, endothelial function (the property of arteries to dilate in order to meet an increased demand of blood, for instance due to a physical effort). Walnuts also reduce harmful cell adhesion molecules which are associated with atherosclerosis, commonly known as hardening of the arteries. These dual effects enhance the circulatory system, therefore aiding in the prevention of heart disease.

70% of Americans not aware of their blood glucose (sugar) level

A new national survey conducted by the American Diabetes Association reveals that 7 out of 10 Americans are not aware of their blood glucose (sugar) level, critical information for determining the presence of diabetes or pre-diabetes. This awareness level is considered extremely low, especially as it relates to individuals' knowledge of blood pressure and cholesterol.

Design of artificial prion may aid fight against mad cow disease

The culprit behind mad cow disease, a.k.a. bovine spongiform encephalopathy, is the most infamous mammalian form of prions. Prions are misfolded proteins that are capable of growing, replicating, and being passed on to daughter cells, that is, they are by themselves heritable. Beyond their disease manifestation, prions also occur naturally in some organisms (such as yeast) and may play important roles in their growth and development. Now, Osherovich and colleagues have identified the amino acid sequences that allow prions to aggregate and replicate, and thereby pass through generations of cells - and prove this by designing an artificial yeast prion that does not exist in nature.

Stem cell research that could help diabetics

University of Florida adult stem cell experts have restored normal blood sugar levels in diabetic mice for three months by chemically coaxing bone marrow cells to produce insulin, a hormone normally made in the pancreas.

Youth obesity provides food for thought

With heart disease developing among children from the age of 10 through poor diet and low activity, young Australians are part of what the World Health Organisation has already termed an "international epidemic of childhood obesity".

Research suggests protein released from lungs could initiate labour

A protein released from the lungs of a developing mouse fetus initiates a cascade of chemical events leading to the mother's initiation of labor, researchers at UT Southwestern Medical Center at Dallas have found.

Study shows Kinerase cream aids skin appearance

Valeant Pharmaceuticals announced that it has introduced Kinerase(R) Intensive Eye Cream, based on the successful formula of its Kinerase facial lotion and cream. The new eye cream contains a 25 percent higher concentration of Kinetin, the natural substance in Kinerase products that helps the skin retain moisture and reduces the appearance of fine lines and wrinkles.

Anti-blood clotting OJ from University of Liverpool

An anti-blood clotting drink has been developed by an up-and-coming biotechnology business based at the University of Liverpool’s Business Incubator, MerseyBIO. Provexis, a medical food company, is in the final stages of its large-scale trial on the new orange juice drink that has been shown to lower the chance of blood clots and thereby reduce risk of heart attack, stroke and the development of deep vein thrombosis.

Enzyme Acetylcholinesterase (AChE), New Approach to Drug Design

French and American researchers have developed a unique approach to drug design where an important neuron-signaling enzyme called acetylcholinesterase (AChE) acts as a microscopic vessel filled with reactant chemicals, to create its own, tailored therapeutic agent.

Researchers discover new form of the Rett syndrome protein

Adrian Bird and Skirmantas Kriaucionis of the University of Edinburgh have discovered a novel form of the protein MeCP2. This alternate form, coined MeCP2 alpha, differs from the original only in the first 19 amino acids. Interestingly, Adrian Bird, Director of the Welcome Trust Centre for Cell Biology at Edinburgh University, found that MeCP2 alpha, is ten times more prevalent not only in the brain but also in other tissues. These findings are currently reported online in Nucleic Acids Research. Similar findings were reported yesterday in Nature Genetics online by Berge Minassian, a neurologist and scientist at Toronto's Hospital for Sick Children.

Decreased collagen may make women more susceptible to pelvic organ prolapse

Decreased collagen levels might make some women more susceptible to pelvic organ prolapse and urinary incontinence, according to a new study by physicians at Temple University School of Medicine and Temple University Hospital. The study, “Collagen content of nonsupport tissue in pelvic organ prolapse and stress urinary incontinence,” appears in a recent issue of the American Journal of Obstetrics and Gynecology.

DNA repair enzymes to fight cancer

The body has a set of DNA repair enzymes that clean up damage to the genome, to reduce potential problems. Many commonly used cancer chemotherapies work by alkylating DNA. However, the DNA repair enzymes are just as capable of repairing this alkylation as if it were damage from any other source, and so they act to overcome the effects of the therapy, reducing its effectiveness.
