Cellular machinery that enables neurons to fire

Cellular machinery that enables neurons to fire
If you ever had a set of Micronauts toy robots with removable body parts you probably had fun swapping their heads, imagining how it would affect their behavior. Researchers supported by the National Institutes of Health have been performing similar experiments on ion channels pores in our nerve cells to sort out the channels' key functional parts. In the November 15 issue of Nature, one group of scientists shows that a part of ion........Go to the Neurology news blog (Added on 11/14/2007 9:52:15 PM)

Predicting the future in ovarian cancer

Predicting the future in ovarian cancer
Kisspeptin and its receptor GPR54 predict a favourable clinical outcome in women with ovarian carcinoma, and are specific for the clear cell carcinoma subtype, research published this week in the online open access journal, BMC Medicine, reveals. The kisspeptins, a family of peptide hormones, and the receptor GPR54 have previously been linked to anti-metastatic activity in certain human tumours. In this study, scientists have shown that........Go to the Ovarian cancer blog (Added on 11/14/2007 9:45:37 PM)

Grape powder blocks genes linked to colon cancer

Grape powder blocks genes linked to colon cancer
Low doses of freeze-dried grape powder inhibit genes associated with the development of sporadic colorectal cancer, University of California, Irvine cancer scientists found. The study suggests that a diet rich in grapes may help prevent the third most common form of cancer, one that kills more than a half a million people worldwide each year. Around 7 percent of all Americans develop colon cancer during their lifetimes. Led by Dr. Randall........Go to the Colon-cancer-blog (Added on 11/14/2007 9:18:56 PM)

Genes influence age-related hearing loss
Waltham, MAA new Brandeis University study of twins shows that genes play a significant role in the level of hearing loss that often appears in late middle age. The research, in the Journal of Gerontology: Medical Sciences, examined genetic and environmental factors affecting hearing loss in the frequency range of speech recognition. This research confirms the importance of genetic factors in age-associated hearing loss, and the need for........Go to the ENT news blog (Added on 11/14/2007 8:42:46 PM)

New therapeutic targets in the treatment of ulcerative colitis

New therapeutic targets in the treatment of ulcerative colitis
Social, environmental and dietary changes are linked to the changes of disease spectrum in a country. Ulcerative colitis has become a usually seen disease in China, probably due to extensive consumption of Western foods in recent years. Unfortunately, the etiology and pathogenesis of ulcerative colitis have not been clarified yet. Therefore, no effective etiological therapy is available at present. But a recent study published in issue 44 of........Go to the GI news blog (Added on 11/13/2007 10:01:54 PM)

Early academic skills, best predict school success
An educational study unprecedented in scope finds that children who enter kindergarten with elementary mathematics and reading skills are the most likely to experience later academic success -- whether or not they have social or emotional problems. We find the single most important factor in predicting later academic achievement is that children begin school with a mastery of early math and literacy concepts, said Northwestern University........Go to the Society medical news blog (Added on 11/12/2007 10:11:08 PM)

How the brain sends eyeballs bouncing
All vision, including reading this sentence, depends on a constant series of infinitesimal jumps by the eyeball that centers the retina on target objectswords or phrases in the case of reading. Such jumps, or saccades, are critical to vision because only the small central region of the retina, called the fovea, produces the clear image necessary for perception.
