Wisconsin scientists grow critical nerve cells

...pathways that relay messages from the brain to the rest of the body. The new findings, reported online today (Jan. 30, 2005) in the journal Nature Biotechnology by scientists from the University of Wisconsin-Madison, are important because they provide critical guideposts for scientists trying to repair d...

New research questions basic tenet of neuron function

...d neurotransmitters, both when the neurons were at rest and when they were active. From these observations, as well as data gathered from electrophysiological techniques, the researchers found two distinct types of vesicles. "The functional differences of these two sets of vesicles may be the result of d...

Deficiency of growth hormone and IGF-1 reduces cancer and kidney disease, but creates other problems

...mals had lower growth hormone and IGF-1 levels the rest of their lives. That had an effect on cancer: 88 percent of "normal" male rats have tumors at death. The male rats that had a lifelong deficiency of growth hormone had substantially fewer tumors ?63 percent ?and the percent of tumors that were fatal...

Scientists document complex genomic events leading to the birth of new genes

...what sets apart humans and other primates from the rest of the animal kingdom. Human chromosome 2 has always intrigued primate biologists; it formed from the fusion of two mid-sized ape chromosomes and is the only cytogenetic distinction separating humans from apes. At the molecular level, however, the ...

Special Imaging Study Shows Failing Hearts Are 'Energy Starved'

Sexual cooperation: Mating increases longevity in ant queens

... and store and use the sperm of their mate for the rest of their lives. Sexual offspring are only produced after several months or years of colony growth, during which a sterile worker force is built up in the population. The fact that mates bond so early reduces the conflict between mating partners becau...

Vascular structure and function improve with diet and exercise

...und measurements of the heart and blood vessels at rest were performed as well. Left ventricular diastolic filling (LVDF) measurements indicate the efficiency of the heart to relax. Left ventricular mass is a measure of end organ damage often following the onset of LVDF abnormalities. The brachial (arm)...

Effective Cancer Treatments Follow The Clock

...e that governs functions like sleeping and waking, rest and activity, fluid balance, body temperature, cardiac output, oxygen consumption and endocrine gland secretion. In their experiments, the researchers measured the animals' body weight as an indicator of response to the anti-cancer drug. They discov...

Multiple Campylobacter Genomes Sequenced

... nerves that join the spinal cord and brain to the rest of the body are damaged, sometimes permanently. Campylobacteriosis is usually caused by C. jejuni, a spiral-shaped bacterium normally found in cattle, swine, and birds, where it causes no problems. But the illness can also be caused by C. coli (also...

Nanoscale Diagnostic Sets Sights on Alzheimer's

...A magnet separates the sandwich complexes from the rest of the sample. The complexes are then heated to release the DNA bar codes, which are then measured by an extremely sensitive detector. Each DNA piece greatly increases the sensitivity of the test and its potential to tell doctors a patient carries th...

Rare surgery performed to remove pancreas, prevent diabetes

...hans would necessarily be discarded along with the rest of the organ. Patients without functioning islet cells have to take insulin for life. Retrieving and relocating the natural insulin-producing cells from the pancreas saves patients from the complications of severe, poorly-controlled diabetes. Loss of...

Live vaccines more effective against horse herpes virus

.... Once infected, a horse carries the virus for the rest of its life in a "latent" (dormant) state. The same symptoms from the initial infection can be reactivated by stress later in life. Osterrieder will present his new findings on vaccine effectiveness, involving a limited study of 15 horses, at a lunc...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...he herd emit intense warning calls that prompt the rest of the herd to clump together for protection and then flee the scene. In 1994, O'Connell-Rodwell recorded the dramatic cries of a breeding herd threatened by lions at Mushara waterhole. "The elephants got really scared, and the matriarch made these ...

Grizzlies set to invade high Arctic?

...nd the rear legs, and faded (grizzled) hair on the rest of the body. Then in the summer of 2004, Dr. England's research group found physical proof that a grizzly bear was indeed calling Melville Island home. Near a cabin used by researchers for temporary stop-overs, they found grizzly bear paw prints in ...

Biochemists report discovery of structure of major piece of telomerase; implications for cancer

...y 10 of the 451 nucleotides. Nobody knows what the rest of the RNA is really doing as part of this enzyme; that is what we're trying to understand. We're getting closer to answering this question." The structure reveals a "pseudoknot" that is required for telomerase activity, at whose core three strands ...

Plant Sacrifices Cells to Fight Invaders

...al moves out of the infected areas and damages the rest of the plant. The group studied the plant-pathogen interactions in a type of tobacco easily infected with a virus in the laboratory. The model system allowed the researchers to inactivate, or silence, a gene important to the plant's PCD response. In...

A little stress gives beneficial oomph! to immune system

...the mice six hours after implantation and from the rest of the mice one, two or three days later. The researchers compared the numbers of leukocytes in each sponge once the sponges were removed. "Just one session of acute stress caused a significant increase in the numbers of leukocytes to collect in the...

After a time-shift, mixed signals from the circadian clock

...t after a significant shift in light schedule, the rest of the brain is transiently--for a duration of about six days--exposed to complex signaling patterns from the circadian clock. The researchers include Henk Albus, Mariska J. Vansteensel, Stephan Michel, and Johanna H. Meijer of Leiden University Med...

Gene keeps neural cells on correct developmental path

...n that permanently turns off neuronal genes in the rest of the body's cells. Now, it turns out that precursor nerve cells contain that same repressive protein after all. In fact, the protein directs the complex network of genes that transforms an embryonic stem cell into a mature nerve cell, say Howard H...
