Genetic switches could lower cost of producing drugs, proteins

Bacteria have evolved complex mechanisms called quorum sensing systems that provide for cell-to-cell communication, an adaptation that allows them to wait until their population grows large enough before mounting an attack on a host or competing for nutrients.

Undernourished stroke patients may have more complications, worse outcomes

Patients who are undernourished when they enter the hospital with an acute ischemic stroke the most common type of stroke, in which blood flow to the brain is blocked are likely to remain undernourished in the hospital and may have worse clinical outcomes, according to a report in the January issue of Archives of Neurology.

Diets high in lutein, zeaxanthin and vitamin E lower risk for cataracts

Women who have higher dietary intake of lutein and zeaxanthin—compounds found in yellow or dark, leafy vegetables—as well as more vitamin E from food and supplements appear to have a lower risk for developing cataracts, according to a report in the January issue of Archives of Ophthalmology, one of the JAMA/Archives journals.

New folic acid seal helps women choose enriched grain foods to help prevent birth defects

Not enough American women understand that consuming the B vitamin folic acid every day can help prevent serious birth defects, and only 40 percent are taking daily multivitamin supplements containing this essential nutrient beginning before pregnancy, two recent surveys show.

Intracellular bacterial communities in cystitis; rifapentine cures TB in mouse model; and more

A study published this week in the open access journal PLoS Medicine presents convincing evidence that intracellular bacterial communities (IBCs) commonly exist in women with bladder infections and may contribute to the recurrence of these infections.

Agent orange chemical, dioxin, attacks the mitochondria to cause cancer

Researchers with the University of Pennsylvania School of Veterinary Medicine have demonstrated the process by which the cancer-causing chemical dioxin attacks the cellular machinery, disrupts normal cellular function and ultimately promotes tumor progression.

Complex path to cell death shown by identification of new genes

Can a tiny winged insect's salivary glands really tell us about processes relevant to human disease? Yes, according to a new study by researchers at the University of Massachusetts Medical School (UMMS), who gained new insights into autophagy - a cellular degradation process associated with a form of programmed cell death - by studying the salivary gland cells of the fruit fly.
