Utilizing laser capture microdissection and highly sensitive ...Exercise effects dependent on time of day
...0 healthy men, between the ages of 20 and 30, were divided into five groups. Four groups exercised vigorously for one hour on a stair-stepper in the morning, afternoon, evening or night. A control group did not exercise. A standard marker, the timing of melatonin secretion, was used to determine the timing o...Gene therapy restores feeding behavior to starving mice
...of the striatum would be involved. The striatum is divided into two segments -- the caudate putamen and the nucleus accumbens. Mark S. Szczypka, a postdoctoral fellow in Palmiters laboratory, attempted to restore dopamine production in the caudate putamen and nucleus accumbens, by injecting harmless ad...High homocysteine levels are strongly associated with all-cause mortality among elderly

The subjectswere divided into quintiles of tHcy concentration ranging from 9.0 mol/L to ³ 20 mol/L. During an average ...Biting may drive division of labor among social wasp workers
... ranging from mild to highly aggressive. O'Donnell divided the behavior into three categories: very mild that could be likened to a light poke in the ribs among humans, slow chewing-like biting, and highly aggressive biting where the recipient is doing its best to escape. "These are not different behavio...Discovery of follicles offers hope of babies for Turners syndrome girls

"To our knowledge this is the first time that follicles have been observed in ovarian tissue from patients with Turners syndrome. Our findings give hope for the future infertility treatment of these girls," he told the...Regeneration in the mammalian heart demonstrated by Wistar researchers
...mice, however, up to 20 percent of the heart cells divided in response to injury. The only species known to demonstrate similar capacities for regeneration are non-mammalian species - certain reptiles and amphibians - able to replace limbs and other body parts. "In more than 15 years of investigations involv......e natural variation found in the U.S." The authors divided the lower-48 states into three broad ecological domains: Eastern Humid Domain, Western Humid Temperate, and Dry Temperate domains. They then combined soil productivity data with elevation and land management information to identify 35 potential soil...A small genetic change makes flu virus deadly
...nd how sick they had made humans. The researchers divided the H5N1 strains into two groups: one that caused systemic lethal infection in the mice and one that was relatively benign. Mice are a good model for studying H5N1, Dr. Kawaoka says, because this virus affects mice and humans similarly. Next, Dr. Ka...New Knox company has big plans for ORNL technology

Second, because of the way the samples are divided into their component parts, the technology offers far greater resolution and preliminary results show that excellent sample separation can be achieved within seconds. Witkowski believes this technique will cause a paradigm shift in the way researcher...Studies offer data on potential impact of Reminyl on caregiver 'burden' in Alzheimer's disease
...art by prescribing 8 mg of Reminyl per day (in two divided doses) for at least four weeks, then increase to the recommended maintenance dose of 16 mg per day. Physicians have the flexibility to increase the daily dose to 24 mg after an additional four weeks.

...he study also demonstrates how the material can be divided into defined arrays to prompt different chemical reactions on different parts of the material. Buriak says this feature can be useful for applications in opto-electronics, bioanalysis or integrating light-emitting devices with silicon chips.

...o served as controls. The alcoholics were further divided into two groups, based on psychiatric evaluation of their alcoholism as Type 1 or 2. DNA was extracted from saliva samples and NPY genotypes determined. It has long been observed that alcoholism runs in families, said Kalervo Kiianmaa, head of the A...NASA unveils spectacular suite of new global data products

Significant peaks in mean longevities occurred in the substages following major mass extinctions in Late Permian, Late Triassic,...Gene chips bring new order to lung cancer types, could yield sharper diagnoses, better drugs
...once, Dana-Farber Cancer Institute scientists have divided lung cancers into new categories based on their gene functions rather than the cells appearance under a microscope. The researchers say its a first step toward a more useful classification of lung cancers that could yield sharper diagnoses and better......over 1000 leading researchers. Faculty of 1000 is divided into 16 subject areas (Faculties), which are subdivided, in turn, into Sections.
