Scientists gain better understanding of how repetitive stretching of endothelial cells that line arteries can make them healthy and resistant to vascular diseases

UCSD researchers stretched cells in a workout chamber the size of a credit card to gain a better understanding of how repetitive stretching of endothelial cells that line arteries can make them healthy and resistant to vascular diseases.

Discovery increases the yield of stem cells from umbilical cord blood

A team of bioengineers led by the University of Toronto has discovered a way to increase the yield of stem cells from umbilical cord blood, to an extent which could broaden therapeutic use of these cells.

Computer model shows biochemical variations, or noise, leads to oscillations in gene regulation that couldn't otherwise be predicted

Geneticists have debated for decades the relative importance of nature versus nurture in determining how an animal looks and behaves, and now University of California, San Diego (UCSD) scientists report that noise could also be an important factor in determining phenotype.

Tumor formation is generated by a complex interaction of both mechanical as well as chemical signals

The relationship between tissue rigidity and tumor formation is fairly well established; however, what is not so well understood is what happens on a molecular level that contributes to such stiffness.

Salicylate an active metabolite of aspirin - weakens lipid membranes

It's well known that high doses of aspirin can cause ulcers and temporary deafness, but the biochemical mechanism responsible for these phenomena has never been deciphered.

How negatively charged lipids stick to negatively charged DNA and self-organize into structures

Scientists studying the structure and interaction of negatively charged lipids and DNA molecules have created a "cookbook" for a class of nontoxic DNA delivery systems that will assist doctors and clinicians in the safe and effective delivery of genetic medicine.

"Ipod-like" device to help correct balance disorders

Researchers at Oregon Health & Science University's Neurological Sciences Institute and the University of Bologna have developed a portable "Ipod-like" device that can be used to help correct balance disorders. Scientists believe this new device, based on auditory feedback of balance, can be worn on the belt like a pager to provide regular therapy for patients with balance disorders, improving their day-to-day activities.

Old skin fungus drug has been found to be a possible cancer treatment

A drug that has been used for 40 years for the treatment of skin fungus has been found to be a possible cancer treatment, according to an international team of scientists. Leslie Wilson, professor of biochemistry and pharmacology at the University of California, Santa Barbara, said that the antifungal drug, griseofulvin, has been shown to inhibit the growth of cancer cells in his laboratory.

Adult, or post-natal, stem cells have the same ability as embryonic stem cells to multiply

In a ground-breaking study, scientists at Children's Hospital of Pittsburgh have discovered that adult, or post-natal, stem cells have the same ability as embryonic stem cells to multiply, a previously unknown characteristic indicating that post-natal stem cells may play an important therapeutic role.

Finding may impact understanding of mechanical facets of many diseases

An international team led by Jeffrey J. Fredberg, professor of bioengineering and physiology at the Harvard School of Public Health, has found that the cell modulates its mechanical properties in much the same way as a glassblower shapes fine glassware.

Breast CT may improve on mammography - more gentler, more accurate

A new breast screening technology that may be able to detect tumors earlier than mammography -- without the need for uncomfortable breast compression -- is being tested in patients at the University of California, Davis, Medical Center.

Obesity appears to worsen and possibly cause asthma

Obesity is a known risk factor for type II diabetes, heart disease and some forms of cancer. Evidence is now mounting that obesity is also a risk factor for asthma.

Simple and efficient method for creation of novel protein functions in an existing protein scaffold

By designing a molecular bridge, scientists at the University of Illinois at Urbana-Champaign have forged a successful pathway through a complex ocean of barriers: They've changed the function of a protein using a co-evolution approach.

First time video capture of chemical signals that traverse human cells messaging

Researchers at UCSD and UC Irvine have captured on video for the first time chemical signals that traverse human cells in response to tiny mechanical jabs, like waves spreading from pebbles tossed into a pond. The scientists released the videos and technical details that explain how the visualization effect was created as part of a paper published in the April 21 issue of Nature.
