Possible treatment found for 'chemobrain'

...in development, learning and memory. Because it is related to the chicken, whose genome has already been sequenced, it will be possible to leverage the chicken genome to get more insight from the zebra finch map. It has been shown that most segments of the human genome originated long before humans themselv...

Suppressing growth hormone in early adulthood may prevent cancer

A modest suppression of growth hormone and related compounds beginning in early adulthood may delay the onset or progression of several types of cancer, researchers from Wake Forest University School of Medicine and other centers reported today at ENDO 2005, the annual meeting of the Endocrine Societ...

Computers close in on protein structure prediction

...if we had explored this part of the space." In a related paper published in the August issue of the journal Proteins, Baker and his colleagues reported that similar approaches can be used to predict the structures of protein complexes. "For the first time, computational methods are able, for a subset of ca...

Vibrio bacteria could be a risk to fish as well as humans

... The new species, Vibrio brasiliensis, seems to be related to Vibrio tubiashii, which has long been known to cause disease in oysters. Professor Austin comments: "Having observed this, the question arose about whether any of these new species could have implications to the health of marine animals. The answ...

New technique could alter field of mouse genetics
