Differently

Tissue regeneration operates differently than expected

Max Planck researchers in Bad Nauheim discover the mechanism by which adult stem cells are integrated into skeletal or heart muscle tissue. There is disagreement, however, about the mechanism on which repair processes are based. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim, Germany, in co-operation with colleagues from Martin Luther University in Halle...

Aspirin reduces cardiovascular risks in men and women -- but differently

Aspirin can significantly reduce the risk of cardiovascular events -- a combined endpoint including stroke, heart attack and death due to cardiovascular disease -- in both men and women, according to a new meta-analysis of more than 95,000 patients by a Duke University Medical Center cardiologist. However, the researchers found, the major reasons for the risk reduction differed between the...

Brain differences could explain why males and females experience pain relief differently

A study conducted by investigators at Georgia State University and the Atlanta-based Center for Behavioral Neuroscience (CBN) reports that anatomical and functional differences in the brain may explain sex differences in the experience of pain and in the effects of certain drugs on pain. The finding, reported in the April 13 issue of the Journal of Comparative Neurology, is the first rep...

African parasite makes component of fat differently from all other organisms

Studying the parasite that causes African sleeping sickness, scientists at Johns Hopkins have discovered a previously unknown way of making fatty acids, a component of fat and the outer layer of all cells. The find unveils more about the biology of this hard-to-kill parasite and could lead to a target for designing new drugs to fight the illness that infects a half-million people and kills 50,000...

UCLA study finds same genes act differently in males and females

UCLA researchers report that thousands of genes behave differently in the same organs of males and females ?something never detected to this degree. Published in the August issue of Genome Research, the study sheds light on why the same disease often strikes males and females differently, and why the genders may respond differently to the same drug. "We previously had no good understandi...

Proteins may behave differently in natural environments

When in an environment similar to that in which they exist naturally, proteins and multiprotein assemblies may demonstrate actions or dynamics different than those they exhibit when in the static form in which they are most often studied, said researchers at Baylor College of Medicine in a report in the current issue of the journal Structure. In a study using electron cryomicroscopy, Dr....
