New clues to repairing an injured spinal cord

New clues to repairing an injured spinal cord

Frogs, dogs, whales, snails can all do it, but humans and primates can’t. Regrow nerves after an injury, that is — while many animals have this ability, humans don’t Continue reading

Why patients with autism spectrum disorder have difficulty noticing ‘being imitated’

Why patients with autism spectrum disorder have difficulty noticing ‘being imitated’

A Japanese research group led by Prof Norihiro Sadato, a professor of the National Institute for Physiological Sciences (NIPS), National Institutes of Natural Sciences (NINS), has found that people with autism spectrum disorders (ASD) have decreased activity in an area in the brain critical for understanding if his/her movement was imitated by others. These results will be published in Neuroscience Research . The research group of Norihiro Sadato, a professor of NIPS, Hirotaka Kosaka, a specially-assigned associate professor of the University of Fukui, and Toshio Munesue, a professor of Kanazawa University measured brain activity by functional magnetic resonance imaging (fMRI) when one’s movement was imitated by others Continue reading

New methods to identify MRSA in pigs

New methods to identify MRSA in pigs

It is important to keep the number of MRSA infections at a low level. In a PhD project at the National Food Institute, Technical University of Denmark, the latest technologies within whole genome sequencing were exploited to develop new methods to identify genes which are important for the survival of MRSA in pigs Continue reading

Flores bones show features of Down syndrome, not a new ‘Hobbit’ human

Flores bones show features of Down syndrome, not a new ‘Hobbit’ human

In October 2004, excavation of fragmentary skeletal remains from the island of Flores in Indonesia yielded what was called “the most important find in human evolution for 100 years.” Its discoverers dubbed the find Homo floresiensis, a name suggesting a previously unknown species of human. Now detailed reanalysis by an international team of researchers including Robert B. Eckhardt, professor of developmental genetics and evolution at Penn State, Maciej Henneberg, professor of anatomy and pathology at the University of Adelaide, and Kenneth Hsü, a Chinese geologist and paleoclimatologist, suggests that the single specimen on which the new designation depends, known as LB1, does not represent a new species.

Genetic cause of common breast tumors found

Genetic cause of common breast tumors found

A multi-disciplinary team of scientists from the National Cancer Centre Singapore, Duke-NUS Graduate Medical School Singapore, and Singapore General Hospital have made a major breakthrough in understanding the molecular basis of fibroadenoma, one of the most common breast tumors diagnosed in women.

High-dose fluticasone effective against eosinophilic esophagitis, study shows

High-dose fluticasone effective against eosinophilic esophagitis, study shows

Results from a clinical trial show that high doses of the corticosteroid fluticasone propionate safely and effectively induce remission in many people with eosinophilic esophagitis (EoE), a chronic inflammatory disease of the esophagus characterized by high levels of white blood cells called eosinophils. However, some trial participants did not respond to fluticasone even after six months of high-dose treatments, providing evidence that certain people with EoE are steroid-resistant. Continue reading

Eating lean beef daily can help lower blood pressure, study suggests

Eating lean beef daily can help lower blood pressure, study suggests

Contrary to conventional wisdom, a growing body of evidence shows that eating lean beef can reduce risk factors for heart disease, according to recent research by nutritional scientists. “This research adds to the significant evidence, including work previously done in our lab, that supports lean beef’s role in a heart-healthy diet,” said Penny M. Kris-Etherton, Distinguished Professor of Nutrition, Penn State. Continue reading

One injection stops diabetes in its tracks: Treatment reverses symptoms of type 2 diabetes in mice without side effects

One injection stops diabetes in its tracks: Treatment reverses symptoms of type 2 diabetes in mice without side effects

In mice with diet-induced diabetes — the equivalent of type 2 diabetes in humans — a single injection of the protein FGF1 is enough to restore blood sugar levels to a healthy range for more than two days. The discovery by Salk scientists, published today in the journal Nature , could lead to a new generation of safer, more effective diabetes drugs Continue reading

Marijuana dependence alters the brain’s response to drug paraphernalia

Marijuana dependence alters the brain’s response to drug paraphernalia

New research from The University of Texas at Dallas demonstrates that drug paraphernalia triggers the reward areas of the brain differently in dependent and non-dependent marijuana users. The study, published July 1 in Drug and Alcohol Dependence , demonstrated that different areas of the brain activated when dependent and non-dependent users were exposed to drug-related cues. The 2012 National Survey on Drug Use and Health shows marijuana is the most widely used illicit drug in the United States. Continue reading
