Study lays groundwork to develop new treatments for cardiovascular disease and other conditions

In a significant step toward restoring healthy blood circulation to treat a variety of diseases, a team of scientists at Weill Cornell Medical College has developed a new technique and described a novel mechanism for turning human embryonic and pluripotent stem cells into plentiful, functional endothelial cells, which are critical to the formation of blood vessels.

Quorum sensing offers a dynamic approach to increase sensitivity to external signals

Researchers at UC San Diego who last year genetically engineered bacteria to keep track of time by turning on and off fluorescent proteins within their cells have taken another step toward the construction of a programmable genetic sensor. The scientists recently synchronized these bacterial "genetic clocks" to blink in unison and engineered the bacterial genes to alter their blinking rates when environmental conditions change.

Rev protein plays essential role in spreading viruses within organism, discover researchers

Professor Denis Archambault of the Department of Biological Sciences of Universit- du Qu-bec - Montr-al (UQAM), and doctoral student Andrea Corredor Gomez have made a major discovery in the field of molecular biology. They have unlocked some of the secrets of a viral protein, known as Rev, which is very different from other proteins of the same type studied to date.

Swedish agency approves Medivir's Xerclear for treatment of cold sores

The Swedish Medical Products Agency has now approved Xerclear™ for treatment of cold sores. It is the first and only topical treatment that has been demonstrated to prevent the incidence of cold sores and shorten healing-times. Xerclear™ will be available from pharmacies in the first half-year 2010.

StemCells receives U.S. patent for propagation and/or derivation of embryonic stem cells

StemCells, Inc. announced today that it has received a Notice of Allowance and a Notice of Issuance from the U.S. Patent and Trademark Office for two patents claiming technologies for the establishment and maintenance of cell pluripotency (the ability to become any cell in the body, which is the defining attribute of embryonic stem cells), including the reprogramming of cells to create pluripotent stem cells.

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.

Optical system for simultaneous imaging electrical and metabolic quantities in the heart

Cardiac rhythm disorders can result from disturbances in cardiac metabolism. These metabolic changes are tightly linked with specific cardiac electrophysiology (CEP) abnormalities, such as depressed excitability, impaired intra- and extracellular conductivities, wave propagation block, and alteration of conduction velocity, action potential amplitude, and duration.

STAT3 is required for proliferation and maintenance of multipotency in glioblastoma stem cells

In a study published online in advance of print in Stem Cells, Tufts researchers report that the STAT3 gene regulates cancer stem cells in brain cancer. Cancer stem cells have many characteristics of stem cells and are thought to be the cells that drive tumor formation. The researchers report that STAT3 could become a target for cancer therapy, specifically in Glioblastoma multiforme (GBM), a type of malignant and aggressive brain tumor.

Chemists create synthetic catalyst that folds its molecular structure into a specific shape

When chemists want to produce a lot of a substance -- such as a newly designed drug -- they often turn to catalysts, molecules that speed chemical reactions. Many jobs require highly specialized catalysts, and finding one in just the right shape to connect with certain molecules can be difficult. Natural catalysts, such as enzymes in the human body that help us digest food, get around this problem by shape-shifting to suit the task at hand.
