Improving diagnosis of cancer by detecting protein-sugar structures

Researchers report in the October 2007 issue of Molecular & Cellular Proteomics that they have developed a new way of detecting the abnormal presence of complexes of sugars and proteins in the blood of cancer patients, thus providing a new tool for cancer diagnosis.

Fungus genome yielding answers to protect grains, people and animals

Why a pathogen is a pathogen may be answered as scientists study the recently mapped genetic makeup of a fungus that spawns the worst cereal grains disease known and also can produce toxins potentially fatal to people and livestock.

Lowering blood pressure protects stroke victims with chronic kidney disease from further strokes

New research, published in the Journal of American Society of Nephrology by The George Institute for International Health in Sydney, has found that lowering blood pressure protects stroke victims with Chronic Kidney Disease from further strokes or heart attacks.

Researchers create modular, multi-functional drug delivery system

There are two aspects to creating an effective drug: finding a chemical compound that has the desired biological effect and minimal side-effects and then delivering it to the right place in the body for it to do its job.

UF researchers test stem cell therapy for heart patients

University of Florida doctors on Wednesday (Oct. 3) treated their first patient enrolled in a new study designed to test whether injecting stem cells into the heart helps restore blood flow to the organ by prompting new blood vessels to grow.

Simplest circadian clocks operate via orderly phosphate transfers

Researchers at Harvard University and the Howard Hughes Medical Institute have found that a simple circadian clock found in some bacteria operates by the rhythmic addition and subtraction of phosphate groups at two key locations on a single protein.

How emotionally charged events leave their mark on memory

Researchers have uncovered new evidence in mice that may explain how emotionally charged situations can leave such a powerful mark on our memories.

Human embryonic stem cells remain embryonic because of epigenetic factors

A human embryonic stem cell is reined in - prevented from giving up its unique characteristics of self-renewal and pluripotency - by the presence of a protein modification that stifles any genes that would prematurely instruct the cell to develop into heart or other specialized tissue.

How Candida albicans transforms from its normally benign form into life-threatening form

Researchers at the Agency for Science, Technology and Research's (A*STAR) Institute of Molecular and Cell Biology (IMCB) have discovered new molecular mechanisms that provide a more detailed understanding of how the normally benign Dr. Jekyll-like fungus known as Candida albicans transforms into a serious and often life-threatening Mr. Hyde-like form.

Discovery offers hope of halting motor neurone disease progression

Scientists have discovered a causal link between the gene for a small protein involved in the formation of blood vessels and the development of some forms of motor neurone disease.

Specific immune deficiency pinpointed as likely cause of ulcerative colitis

In a series of mouse experiments, researchers at the Harvard School of Public Health (HSPH) have pinpointed a specific immune deficiency as the likely fundamental cause of ulcerative colitis, a chronic, sometimes severe inflammatory disease of the colon or large intestine that afflicts half a million Americans.
