Genetically engineered herpes simplex virus keeps arteries free-flowing

A genetically engineered herpes simplex virus, primarily known for causing cold sores, may help keep arteries "free-flowing" in the weeks following angioplasty or stent placement for patients, according to research published early in the online edition of PNAS (Proceedings of the National Academy of Sciences of the United States of America).

Cicardian system suffers and protects from prenatal cocaine exposure

Researchers from Boston University School of Medicine (BUSM) have shown that prenatal cocaine exposure in zebrafish (which share the majority of the same genes with humans) can alter neuronal development and acutely dysregulate the expression of circadian genes and those affecting melatonin signaling, growth and neurotransmission.

Discovery of gallstone gene

Scientists at the University of Bonn, together with colleagues from Romania, have discovered a gene variant that significantly increases the risk of developing gallstones (Hepatology No. 46, 11 July 2007, DOI 10.1002/hep.21847).

How immune cells catch pathogens

To protect us from disease our immune system employs macrophages, cells that roam our body in search of disease-causing bacteria. With the help of long tentacle-like protrusions, macrophages can catch suspicious particles, pull them towards their cell bodies, internalise and destroy them.

Top brain experts say alcohol does not destroy brain cells

At an international neural stem cell conference in Australia, ninety of the world's top scientists in neural stem cell and brain development research, from 11 different countries were brought together last month by the Queensland Brain Institute (QBI).

Uncooked fish linked with liver cancer in Asia

An age old preference for eating uncooked fish dishes like koi-pla puts people in SE Asia at risk of ingesting trematodes that can cause a type of liver cancer called cholangiocarcinoma (cancer of the bile ducts), say researchers in this week's PLoS Medicine.

No compelling evidence that meditation has therapeutic value

While it's not likely to do you any harm, there is also no compelling evidence that meditation has therapeutic value, says a new report from the University of Alberta.

Scientists identify two brain networks in Parkinson's

The disease that causes tremors, rigidity and slowed movements in a million Americans also targets another brain network that regulates cognitive thought and the ability to carry out everyday tasks.

Scientists take exciting approach for attacking cancers

A new study identifies a combination therapy that may sensitize human cancer cells to a promising treatment currently being used in clinical trials.

Researchers discover how microRNAs control protein synthesis

While most RNAs work to create, package, and transfer proteins as determined by the cell's immediate needs, miniature pieces of RNA, called microRNAs (miRNAs) regulate gene expression.

New gene mutation linked to frontotemporal dementia

Researchers have identified a new gene mutation linked to frontotemporal dementia, according to a study published in the July 10, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

New weapon in the battle against antibiotic-resistant bacteria

Putting bacteria on birth control could stop the spread of drug-resistant microbes, and researchers at the University of North Carolina at Chapel Hill have found a way to do just that.

Neutral genetic drift

Johns Hopkins researchers have added to the growing mound of evidence that many of the genetic bits and pieces that drive evolutionary changes do not confer any advantages or disadvantages to humans or other animals.

Gene therapy offers promising approach to tackle pancreatic cancer

A molecularly engineered therapy selectively embeds a gene in pancreatic cancer that shrinks or eradicates tumors, inhibits metastasis, and prolongs survival with virtually no toxicity, researchers from The University of Texas M. D. Anderson Cancer Center report in the July 9 edition of Cancer Cell.

Debate on folic acid fortification

Since the institution of nationwide folic acid fortification of enriched grains in the mid 1990s, the number of infants born in the United States and Canada with neural tube defects has declined by 20 percent to 50 percent.

More muscle for the argument to give up smoking

Researchers at The University of Nottingham have got more bad news for smokers. Not only does it cause cancer, heart attacks and strokes but smokers will also lose more muscle mass in old age than a non-smoker. The effect of this predisposes smokers to an accelerated decline in physical function and loss of independence.
