‘Golden approach’ human proteine classification
Proteomics on a chip
Knowledge of the human proteome may provide us with even more insight than knowledge of DNA. This ‘protein blueprint’ of a human contains valuable information about cell properties and disease causes. A single cell, however, already consists of several thousands of proteines. To be able to classify them, dr. Richard Schasfoort of the University of Twente is developing a special chip, able to make hundreds or tho
João Pedro Magalhães, researcher in the Biology of Aging, suggests, in work published in the June edition of the magazine “Experimental Gerontology” and entitled “The evolution of mammalian aging”, that the study of certain species of reptiles and amphibians that apparently do not age could lead to discoveries about aging.
For this Portuguese scientist the secret of eternal youth could be in the relationship, already scientifically shown, between the size and longevity of different species
The long-sought ability to control the movement of prosthetic limbs with brain waves has edged a little closer to reality.
In experiments published in the June 7 issue of the journal Science, monkeys were able to move balls around in 3D space on a computer screen just by thinking about it. With a little practice, they got even better at it.
“They achieved nearly the same accuracy and speed as normal arm movements,” said senior author Andrew Schwartz, Ph.D., of the Departme
Finding may help explain related conditions in people
Inactivating just one of more than two dozen similar genes can cause temporary but profound hair loss, known as alopecia, in mice, researchers from Johns Hopkins and the Pasteur Institute in France report in the June issue of Genes & Development.
Surprisingly, the impact of loss of this keratin 17 gene (K17) depended on an animals genetic make-up: its loss caused no effect in one strain of mice and complete alopecia in an
Study has implications for lowering heart-disease risk in Type 2 diabetes patients
A drug used widely as an insulin sensitizer appears also to have a significant anti-inflammatory effect in diabetics, a property that could make it useful in helping to prevent heart disease in these patients, a study by endocrinologists at the University at Buffalo has found.
Results of the research, involving the drug rosiglitazone, were presented here today (June 15, 2002) at the annual mee
Researchers at The Hospital for Sick Children (HSC), the University Health Network (UHN), and the University of Toronto (U of T) have identified a novel gene that when mutated results in medulloblastoma, the most common malignant brain tumour found in children. This research is reported in the July issue of the scientific journal Nature Genetics.
Brain tumours are the second most common cancer in children after leukemia, with the incidence increasing at a rate of five to 10 per cent per yea
Investigators reporting at the 49th Annual Meeting of the Society of Nuclear Medicine (SNM) have determined that a noninvasive nuclear medicine technique can accurately and safely detect the extent of persistent heart muscle damage after a heart attack. In two studies, researchers reported on the safety and efficacy 201Tl/99mTc Annexin (ApomateTM) SPECT in detecting and localizing myocardial tissue damage and revealing areas of persistent cellular injury. SPECT (single-photon emission computed tomogr
Farmers growing corn in the mid-Atlantic region will have a new tool to help them identify appropriate cultural practices for the types of soils in their fields, thanks to research conducted by researchers from Virginia Tech and Colorado State University.
“Soils vary in their ability to hold water,” said Mark Alley, professor of crop and soil environmental sciences at Virginia Tech. “If a farmer knows the water-use efficiency of the soils in his field, he has a very important clue on how to mana
After 15 years of observation and a lot of patience, the worlds premier planet-hunting team has found a planetary system that reminds them of our home solar system.
Geoffrey Marcy, astronomy professor at the University of California, Berkeley, and astronomer Paul Butler of the Carnegie Institution of Washington, D.C., today announced the discovery of a Jupiter-like planet orbiting a Sun-like star at nearly the same distance as the Jovian system orbits our sun.
“All other extr
Violence, bereavement, debt and other stressful experiences do not increase the chances of breast cancer returning in a woman who has been treated for the disease.
The good news was announced today in a new study by Europe`s largest cancer charity, Cancer Research UK, and published in the British Medical Journal.
The study, headed by Professor Amanda Ramirez at Cancer Research UK`s London Psychosocial Group, looked at more than 200 women with operable breast cancer and followed thei
