Lower Fetal Weight Linked to High Distress in Mothers

...nborn baby. “Maternal distress is accompanied by biochemical changes, such as increased cortisol, that can both directly and indirectly affect the fetus,” Diego said. “Cortisol can directly cross through the placenta into the fetus, which could affect fetal development." The study, in the September-October i...

"Dynamic Energy Landscape" of enzyme in Catalysis

...protein molecules called enzymes catalyze specific biochemical reactions in cells. The traditional theory is that dynamic fluctuations//protein conformation or structure play a major role in enzyme catalysis. However, recent findings reveal that it is the "dynamic energy landscape" of the enzyme that directs it ...

Cancer Rates Falls In Younger Men But Stable In Young Women

...nvironmental link for thyroid cancer, Meg Sears, a biochemical engineer and science analyst in Ottawa disagrees. Sears said, “Old people may get cancers because their cells have reproduced so many times they've got genetic changes and then things go wrong. But when young people get cancer it's either because of ...

Cranberry Juice Could Fight E. coli Bacteria

... The new findings paint a detailed picture of the biochemical mechanisms that may underlie a number of beneficial health effects of cranberry juice that have been reported in other studies over the years. It shows that the tannins found primarily in cranberries affect E. coli in three devastating ways, all of...

Genome Code Cracked for Breast and Colon Cancers

... sequence determined using more than three million biochemical reactions. The sequences were fed through computer software that matches up normal sequences with those from tumor samples. The software highlighted more than 800,000 suspicious regions that were visually inspected, one by one, to verify that they we...

Obesity Takes its Toll on IQ of Toddlers

...at early-onset morbid obesity and these metabolic, biochemical problems can also lead to cognitive impairment.' Driscoll and his colleagues conducted their studies on 18 children and adults with early-onset morbid obesity that is with a weight at least 150 per cent of their ideal body weight before age four. ...

Deadly Lung Disease Sends Patients on ‘Quest for Breath

...ientists at the U-M Medical School have identified biochemical signals that attract pathogenic cells to damaged lung tissue – one of the first steps in a chain of events leading to IPF. Bethany B. Moore, Ph.D., Galen B. Toews, M.D., and other Medical School researchers hope their work will help to unravel the ...

A New Breed Of Mice Might Hold The Key For Depression Treatment

...ing separate behavioural, electrophysiological and biochemical measures known to gauge 'depression' in animals," says Dr. Debonnel. "The results really surprised us; our 'knock-out' mice acted as if they had been treated with antidepressants for at least three weeks." This research represents the first time de...

Processed foods – "the" cause of obesity!

...tose tastes like sugar and is used as a sugar, its biochemical structure is different from sugar, which prevents ... sugar," he explains. Lustig sums up on how these biochemical disorders are the root causes of obesity: "The higher your insulin, the more your brain thinks you'r...

Scientist Discovers Crucial Part of Blood-Clotting Process

... and other substances can bind to activate or stop biochemical reactions in the cell. By revealing how factor IXa works, it should be possible to make synthetic chemicals that prevent strokes and heart attacks, Dr. Neuenschwander said. Conversely, you could make synthetic activators that could stop the unwante...

Aging Critical For Alzheimer's Disease

...r fifth decade. "It was very satisfying when the biochemical data from Jeffery's lab and genetic results from our lab came together," recalls Dillin. Both scientists are continuing the collaboration by searching for small molecules that delay the aging program and boost protective mechanisms. Other contribut...

Antioxidants Could Halt Rocky Mountain Spotted Fever

...cells, as seen by electron microscopy, and through biochemical evidence proving oxidative stress (OS), a term used to describe a level of damage in cells, tissue and organs. Antioxidants can generally neutralize free radicals and reduce oxidative damage. Earlier experiments in which scientists infected cells wit...
