The new graduate training program parallels HHMI's commitment to bring together biologists, computer scientists, engineers, physicists, chemists, and mathematicians to conduct collaborative research at Janelia Farm, HHMI's new research campus now under construction in Loudoun County, Virginia....

New fruitfly model of diabetes has future implications for pancreatic cell transplantation

... cells in the brain of the fly make insulin, which parallels the role of beta cells in humans. Now, in the September 16 issue of Nature, the researchers describe cells that produce a glucagon-like hormone, which are akin to alpha cells in mammals. These two cell types within the pancreatic islets are the main ...

Mouse study shows NPAS3 and NPAS1 genes may be linked to psychosis

... Dr. McKnight said. "It's difficult to draw direct parallels between the simple behavioral abnormalities observed in the mutant mice and the complex, delusional cognitive defects that characterize human schizophrenia. Our results may turn out to have nothing to do with schizophrenia, or they could point to som...

Early clinical treatment can halt progression of Alzheimer's disease, UCI researchers find

...eutic treatment in a mouse model that more closely parallels the twin pathology that occurs in the human Alzheimer's-diseased brain. Details of the Study: In the study, the researchers used transgenic mice that LaFerla's lab had previously developed. Because mice normally don't get Alzheimer's, human genes ...

Obesity and hypertension: Two epidemics or one?

...e the case. Cardiac output is elevated at rest and parallels the increase in resting oxygen consumption, whereas systemic vascular resistance is similar or reduced in obese compared with non-obese individuals. There is some evidence that abdominal obesity is associated with altered blood circulation adjustme...

Evidence of nanobacterial-like structures found in human calcified arteries and cardiac valves

...nes occur. The sequence of maturation also roughly parallels the evolution of the mammalian brain, suggest Drs. Nitin Gogtay, Judith Rapoport, NIMH, and Paul Thompson, Arthur Toga, UCLA, and colleagues, whose study is published online during the week of May 17, 2004 in The Proceedings of the National Academy o...

Bird's song may be linked to speech disorders

UCLA scientists report parallels between human speech and the song of a bird, findings that may contain clues to human speech disorders. The research by a team led by Stephanie White, UCLA assistant professor of physiological science, supports the theory that two genes shared by hum...

Newly identified gene linked to brain development

...en thought that the evolution of the frontal lobes parallels the development of human communication and civilization," Walsh adds. "The GPR56 gene is only found in higher animals that possess a frontal lobe. It has undergone significant changes, even among these species, suggesting it may be a target of evolut...

For some gorillas, local kin may mean local peace

Gene essential for development of normal brain connections resulting from sensory input discovered

... response to sensory experience after birth. This parallels some learning disorders in humans where the child appears normal initially, but by the age of two or three years it becomes clear that there are failures in the acquisition of new knowledge." Neurons from normal mice develop a highly branched tree-li...

'Smart bomb' delivery destroys tumors in mice

Not present in whole, unbroken cloves of garlic, allicin is the product of a biochemical reaction between two substances stored apart in tiny, adjoining compartments within each clove. The two are an enzyme, ...

New findings implicate cell size controls in a variety of diseases

...ith LSI cell biologist Daniel Klionsky to look for parallels between this mammalian version of TOR (mTOR), and a molecule Klionsky studies in yeast called just TOR which performs similar functions. "It will be great to have Dan as my neighbor," said Guan, whose office is just steps away from Klionsky's on the...

Lab tests can reveal how patients respond to Gleevec

...but so far preliminary data suggest that there are parallels with KIT @ that is, if a PDGFRA mutation is present, then Gleevec response can be predicted by the exact type of mutation," Heinrich said. The study results suggest that clinical testing for specific mutation type may help clinicians treat patient...

Study of primitive life form expected to provide clues to biological processes in higher organisms

...much faster than the second. More importantly, the parallels between microbial and human puzzles mean that completing the first puzzle will make solving the second one easier and faster." The organism the Kennelly lab is studying is called Sulfolobus solfataricus, an extremophile from the "third domain of lif...

Genes that regulate hearing link humans and fruit flies in new way

...al biologists have known that there are remarkable parallels between fruit fly and human genetics, but the parallels have been restricted to tissues and organs that existed before the evolutionary divergence of verteb...

New book says Northwest salmon could face same fate as those in Northeast, England
