Berkeley Lab Researchers Find New Evidence on How Cholesterol Gets Moved from HDLs to LDLs

Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have found new evidence to explain how cholesteryl ester transfer protein (CETP) mediates the transfer of cholesterol from “good” high density lipoproteins (HDLs) to “bad” low density lipoproteins (LDLs). These findings point the way to the design of safer, more effective next generation CETP inhibitors that could help prevent the development of heart disease. (more…)

In The Mouth, Smoking Zaps Healthy Bacteria, Welcomes Pathogens

COLUMBUS, Ohio — According to a new study, smoking causes the body to turn against its own helpful bacteria, leaving smokers more vulnerable to disease.

Despite the daily disturbance of brushing and flossing, the mouth of a healthy person contains a stable ecosystem of healthy bacteria. New research shows that the mouth of a smoker is a much more chaotic, diverse ecosystem—and is much more susceptible to invasion by harmful bacteria. (more…)

Radiation Generates Cancer Stem Cells From Less Aggressive Breast Cancer Cells

Breast cancer stem cells, thought to be the sole source of tumor recurrence, are known to be resistant to radiation therapy and don’t respond well to chemotherapy.

Now, researchers with the UCLA Department of Radiation Oncology at UCLA’s Jonsson Comprehensive Cancer Center report for the first time that radiation treatment, despite killing half of all tumor cells during every treatment, transforms other cancer cells into treatment-resistant breast cancer stem cells.

COLUMBUS, Ohio – Water-associated infectious disease outbreaks are more likely to occur in areas where a region’s population density is growing, according to a new global analysis of economic and environmental conditions that influence the risk for these outbreaks.

Ohio State University scientists constructed a massive database containing information about 1,428 water-associated disease outbreaks that were reported between 1991 and 2008 around the world. By combining outbreak records with data on a variety of socio-environmental factors known about the affected regions, the researchers developed a model that can be used to predict risks for water-associated disease outbreaks anywhere in the world.

When Nerve Meets Muscle, Biglycan Seals The Deal

In the absence of the protein biglycan, synapses at neuromuscular junctions in mice began to break up about five weeks after birth, according to a new study led by Brown University researchers. Reintroducing byglycan helped fix the loss of synaptic stability in cell culture. The research may be relevant to efforts to treat motor neuron diseases, such as amyotrophic lateral sclerosis (ALS, Lou Gehrig’s Disease) and spinal muscular atrophy. (more…)

New Device Removes Stroke-Causing Blood Clots Better Than Standard Treatment

An experimental device for removing blood clots in stroke patients dramatically outperformed the standard mechanical treatment, according to research presented by UCLA Stroke Center director Dr. Jeffrey L. Saver at the American Stroke Association’s 2012 international conference in New Orleans on Feb. 3.

The SOLITAIRE Flow Restoration Device is among an entirely new generation of devices designed to remove blood clots from blocked brain arteries in patients experiencing stroke. It has a self-expanding, stent-like design and, once inserted into a clot using a thin catheter tube, it compresses and traps the clot. The clot is then removed by withdrawing the device, thus reopening the blocked blood vessel. (more…)
