Parainfluenza virus found in Hong Kong patients

A CHP spokesman said PIVs are spread by respiratory secretions through close contact with infected persons or contact with contaminated surfaces or objects.

Researchers attempt to quantify processes underlying cell heterogeneity

Combining the latest methods in gene splicing and computer modeling, Rice University researchers are trying to develop a predictive framework for one of the most basic and complex biological phenomena — cellular heterogeneity, or the ability of genetic clones to act and behave differently when exposed to the same set of environmental stimuli.

STAT3 protein could lead to new ways to prevent skin cancer

Scientists at The University of Texas M. D. Anderson Cancer Center have identified a protein that serves as a master regulator of skin cancer - a finding that could lead to new ways to prevent skin cancer before it starts.

New role for a key protein involved in muscle contraction

Overturning a scientific stereotype, researchers at the University of Illinois at Chicago have discovered a new role for a key protein involved in muscle contraction and shown it is present not just in the cytoplasm of cells but in the nucleus as well.

Red wine delivered though an aerosol for COPD, asthma, and possibly even arthritis

Homing in on mechanisms for the reported effectiveness of resveratrol, which is found in red wine, researchers at Imperial College London, England, confirmed its broad anti-inflammatory action, and found potential for applications in chronic obstructive pulmonary disease (COPD), asthma, and possibly even arthritis.

Micro-array technology is revolutionising current drug development

Gene expression micro-array technology is benefiting all phases of the discovery, development and subsequent use of new cancer therapeutics

Researchers are one step closer to understanding how high carbohydrate diets lead to obesity and diabetes

Researchers at UT Southwestern Medical Center at Dallas are one step closer to understanding how high carbohydrate diets lead to obesity and diabetes.

Researchers stimulate the body to repair tissue damaged by peripheral arterial obstructive disease

Duke University Medical Center researchers have shown that they can stimulate the body to produce its own naturally occurring growth factors to promote blood vessel growth into tissue damaged by peripheral arterial obstructive disease (PAOD).

Researchers suggest how to generate B cells from stem cells

Before stem cells, of whatever origin, can be used to treat patients, scientists will need to learn how to coax them to develop into the desired cell types, a major challenge.

First use of technology called ubiquitin-mediated fluorescence complementation to study a cell-signaling mechanism called ubiquitination

Researchers at the University of Michigan Medical School and Howard Hughes Medical Institute have found a way to see proteins in cells that have been tagged by a molecular “sticky note” called ubiquitin.

Discovery of key molecular step which allows cancer cells to move to different parts of the body

Researchers at The University of Texas M. D. Anderson Cancer Center have figured out a key molecular step by which a cancer cell can unhook itself from the mesh weave of other cancer cells in a tumor, and move away to a different part of the body - the process, known as metastasis, that makes cancer so dangerous.

HER-2 cell surface receptors tun on genes associated with carcinogenesis

Researchers at The University of Texas M. D. Anderson Cancer Center now have evidence that receptors found on tumors that were believed to function only on the surface of cells can actually switch on genes inside a cell's nucleus, thus promoting cancer development in two distinct ways.

Liver cancer genes cluster into two subsets that correlate to survival

An analysis of the gene expression patterns of 91 unrelated liver tumors revealed two distinctive subclasses highly associated with patient survival, according to a new study published in the September 2004 issue of Hepatology.

New view of chromatin and gene activity

A genome - the DNA instructions for an organism - does not act alone. DNA is packaged with proteins into 'chromatin', which may be more or less tightly condensed. A popular proposal is that active genes are in 'open' chromatin (to allow access to them) and inactive genes are in tightly packed 'compact' chromatin.
