Now, Selman and coworkers present in an article published in the online, open-access journal PLoS ONE on Wednesday 30th May, strong evidence indicating that a subset of IPF patients has a short duration of symptoms before diagnosis and display an accelerated clinical course to end-st...

Salk scientists hammer out a pathway that promotes muscle cell survival in mice

..."In addition to muscle, this regulatory circuit is present in brain and heart tissue, where it also seems to control cell survival," said Marc Montminy, M.D., Ph.D., professor in the Clayton Foundation Laboratories for Peptide Biology at the Salk Institute and senior author of the study. "Therefore, we belie...

Ecology in an era of globalization

In "The future of production systems in a globalized world," Elena Bennett (McGill University, Montreal, Canada) and Patricia Balvanera (Universi...

Chronic fatigue syndrome impairs a person's slow wave activity during sleep

...ow a blunted SWA response to sleep challenge. The present CFS study included only women, and none had current depression. Therefore, our results cannot be explained on the basis of depression." Experts recommend that adults get between seven and eight hours of sleep each night to maintain good health a...

The sound of proteins

...logy describes how researchers have found a way to present human proteins as musical notes. Rie Takahashi and Jeffrey H. Miller from the University of California, Los Angeles, USA, have so far transcribed segments of two human proteins into music. But to make their melodies more pleasing on the ear, they ha...

Climate change impacts stream life

...o been clear." The study predicts that at the present rate the springtime abundance of macroinvertebrates in streams could decline by as much as 21 per cent for every 1 degree Celsius rise in temperature. Dr Durance added "The numbers of species in the streams we examined might also fall by 12-25 pe...

Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness

... "In broad terms, the results of these experiments present a novel role for nitric oxide in regulating the activity of G-protein coupled receptors," Lefkowitz said. "Also, the findings point to the possibility that deficiencies in the activity of nitric oxide, which occurs in common disorders such as high bl...

Corals -- More complex than you?

...f the genes involved in innate immunity in man are present in coral ?and just how similar they are." The significance of this may lie in the fact that scientists now suspect coral is facing a number of pandemics: ‘black band? ‘white plague? ‘white pox?‘white syndrome?and ‘white band?are the names of some ...

Brain's white matter -- More 'talkative' than once thought

...oscopic hunt revealed that pools of glutamate were present in the nerve fibers wherever they touched OPCs. All of the nerve cells in the white matter that released glutamate within reach of OPCs, moreover, had something in common: no myelin insulation. Normally myelin speeds electrical impulses. Cells la...

Scientists: As rainfall changes, tropical plants may acclimate

...e Proceedings of the National Academy of Sciences, present a notable exception to the commonly held idea that tropical plants are highly specialized in their own little environmental niches ?and thus very sensitive to disturbances of those niches. That could be good for the plants because climate change i...

UCLA AIDS Institute researchers find a peptide that encourages HIV infection

... School of Medicine at UCLA and a co-author of the present study. Unexpectedly, the researchers discovered that while retrocyclin-1 inhibited infection of CD4 cells with HIV-1 by about 95 percent, the RC-111 variant enhanced viral infection five-fold. There are three structural varieties of peptides, als...

Researchers publish first marsupial genome sequence

...rs were able to pinpoint genetic elements that are present in placental mammals, but missing from marsupials —that is, the genetic factors that may underlie many of the differences between the two types of mammals. Interestingly, about one-fifth of the key functional elements in the human genome arose du...

Dealing deadly cancers a knockout punch

...ls containing an activated ras pathway, a mutation present in about two-thirds of all human cancers. Reovirus enters a cancer cell, makes thousands of copies of itself, and then causes the cell to burst, which releases viruses that infect and kill adjacent cancer cells. Normal cells are not harmed.
