University of Michigan scientists discover how SEVI works

Since the discovery in 2007 that a component of human semen called SEVI boosts infectivity of the virus that causes AIDS, researchers have been trying to learn more about SEVI and how it works, in hopes of thwarting its infection-promoting activity.

Scientists anticipate new approaches in drug development to combat prion infection

The regulating protein Srebp2 drives cholesterol formation, which prions need for their propagation, in prion-infected neuronal cells. With these findings, published in the current issue of the Journal of Biological Chemistry, scientists of Helmholtz Zentrum München and Technische Universität München anticipate new approaches in drug development to combat prion infection.

Detrimental bacterial DNA identification method for use in winemaking developed

In winemaking, grape juice is turned to wine during the fermentation process by the action of a number of essential beneficial microorganisms -namely bacteria. Sometimes, though, harmful bacteria also populate the fermentation vat, spoiling the wine in the process.

Scientists closer to unraveling the mechanisms of gene regulation

A team led by Penn State's Ross Hardison, T. Ming Chu Professor of Biochemistry and Molecular Biology, has taken a large step toward unraveling how regulatory proteins control the production of gene products during development and growth.

Sugar-coated polymer may offer a new solution for allergy and asthma

Scientists at Johns Hopkins and their colleagues have developed sugar-coated polymer strands that selectively kill off cells involved in triggering aggressive allergy and asthma attacks. Their advance is a significant step toward crafting pharmaceuticals to fight these often life-endangering conditions in a new way.

GERD is an immune-mediated injury and not the result of acid burn, says new study

Contrary to current thinking, a condition called gastroesophageal reflux disease (GERD) might not develop as a direct result of acidic digestive juices burning the esophagus, UT Southwestern Medical Center researchers have found in an animal study.

NIEHS grants $13 million for engineered nanomaterials research

The National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health, is increasing its investment in understanding the potential health, safety and environmental issues related to tiny particles that are used in many everyday products such as sunscreens, cosmetics and electronics. The NIEHS will award about $13 million over a two-year period, through the American Recovery and Reinvestment Act, to bolster the NIEHS's ongoing research portfolio in the area of engineered nanomaterials (ENMs).

Workshop on "Neuroeconomics and Endocrinological Economics" organized

A workshop on "Neuroeconomics and Endocrinological Economics," to be held Nov. 20 and 21 at UC Davis, will be the first to bring together experts in neuroscience, economics and hormone physiology in one event, according to organizers.

Particles released by car brake pads can harm lung cells: Study

Real-life particles released by car brake pads can harm lung cells in vitro. Researchers writing in BioMed Central's open access journal Particle and Fibre Toxicology found that heavy braking, as in an emergency stop, caused the most damage, but normal breaking and even close proximity to a disengaged brake resulted in potentially dangerous cellular stress.

Low-level laser therapy increases tumour growth in skin cancer

High irradiances of low-level laser therapy (LLLT) should not be used over melanomas. Researchers writing in the open access journal BMC Cancer studied the pain relieving, anti-inflammatory 'cold laser', finding that it caused increased tumour growth in a mouse model of skin cancer.

Embryonic stem cells raise hope of cellular replacement therapy for liver failure

Embryonic stem (ES) cells, known for their capacity to proliferate indefinitely and differentiate into almost all types of cells including hepatocytes, have raised the hope of cellular replacement therapy for liver failure. There have been several protocols available for hepatic fate specification from ES cells, however, most of the protocols currently used result in low yield or purity of functional hepatocytes. Valproic acid (VPA), a histone deacetylase inhibitor, has been demonstrated to facilitate the hepatic differentiation of mesenchymal stem cells. However, little is know about whether VPA could induce the hepatic differentiation of ES cells.

UCLA study: Structural changes in brain may help offset vision loss and strengthen other senses

Visually impaired people appear to be fearless, navigating busy sidewalks and crosswalks, safely finding their way using nothing more than a cane as a guide. The reason they can do this, researchers suggest, is that in at least some circumstances, blindness can heighten other senses, helping individuals adapt.
