Lack of tumor suppressor gene rb2/p130 could be an early indicator of prostate cancer, say Temple Univ. researchers

The progressive lack of the tumor suppressor gene Rb2/p130 could be an early indicator of prostate cancer in males, according to a study by researchers at Temple University’s College of Science and Technology.

The results of the study, “Expression of Cell-Cycle-regulated Proteins pRb2/p130, p107, p27kip1, p53, Mdm-2, and Ki-67 (MIB-1) in Prostatic Gland Adenocarcinoma,” appear in the June issue of Clinical Cancer Research ( clincancerres.aac

Polymer protects grass

To help the nature to recover from harmful impacts of the mining industry, Svetlana Mesyats and her team from the Geological Institute of the Kola Research Center RAS offer the method, which implies the application of a thin invisible polymeric film onto the soil surface and provides for a fast and successful minesite recultivation.Polymer Protects Grass

It is not surprising that such a polymeric covering is invented in Apatity. People leaving on the Cola Peninsula often need to dea

Fish Blood Preserves Sperm

In the Arctic and Antarctic seas the water gets cold to minus 1.9 C in winter, but somehow some fish live there. These cold-blooded creatures survive in the icy water because the blood in their veins contains antifreeze proteins and glycoproteins. High levels of the antifreeze proteins are found in the blood serum, they are present in cell cytoplasm and all body fluids except urine. Due to their structure, molecules of antifreeze glycoproteins (AFGP) prevent growth of ice crystals. Natural antifreeze

Methamphetamine drastically increases virus’ ability to replicate in brain tissue

A controversial research study here has found that exposing cells infected with feline immunodeficiency virus – a surrogate for HIV – to methamphetamine increases those cells’ ability to replicate the deadly virus as much as 15-fold.

The finding, if confirmed by ongoing animal studies, could answer important questions about how lentiviruses such as FIV and HIV can gain a foothold in the brain. That knowledge is vital in slowing or lessening the dementia that often accompanies AIDS and s

Black holes in distant galaxies point to wild youth, Chandra discovers

Like ’flower power’ tattoos on aging ex-hippy baby boomers, unexpectedly large numbers of neutron stars and black holes in elliptical galaxies suggest some of these galaxies lived through a much wilder youth. The discovery by NASA’s Chandra X-ray Observatory may require a revision of how elliptical galaxies evolved.

“For the first time, Chandra has allowed us to distinguish hundreds of star-like sources that are black holes and neutron stars in distant elliptical galaxies,” said Craig Sara

Climate change may become major player in ozone loss

While industrial products like chlorofluorocarbons are largely responsible for current ozone depletion, a NASA study finds that by the 2030s climate change may surpass chlorofluorocarbons (CFCs) as the main driver of overall ozone loss.

Drew Shindell, an atmospheric scientist from NASA’s Goddard Institute for Space Studies (GISS) and Columbia University, N.Y., finds that greenhouse gases like methane and carbon dioxide are changing the climate in many ways. Some of those effects include wat
