Patterns of brain activity that play a role in recall of memories and decision-making

UCSF scientists have identified patterns of brain activity in the rat brain that play a role in the formation and recall of memories and decision-making. The discovery, which builds on the team's previous findings, offers a path for studying learning, decision-making and post-traumatic stress syndrome.

U.N.-sponsored report finds 1 in 10 infants born prematurely worldwide

Fifteen million infants, or nearly one in 10 worldwide, "are born premature every year, and 1.1 million of those infants die, according to a U.N.-sponsored report released Wednesday," Agence France-Presse reports.

Awake mental replay essential for making informed choices

Awake mental replay of past experiences is essential for making informed choices, suggests a study in rats. Without it, the animals- memory-based decision-making faltered, say scientists funded by the National Institutes of Health. The researchers blocked learning from, and acting on, past experience by selectively suppressing replay - encoded as split-second bursts of neuronal activity in the memory hubs of rats performing a maze task.

Improved lung-cancer screening by combining blood test with CT imaging

National Jewish Health is seeking to refine and improve lung-cancer screening by combining a blood test with CT imaging to detect disease earlier and more effectively. The trial combines a CT chest scan and the EarlyCDT-Lung blood test to screen for cancer, and seeks to build on recent research demonstrating that CT screening alone can reduce lung-cancer mortality.

Nature publishes first of two controversial studies on H5N1 avian flu

"In a long-awaited study that helped prompt a contentious debate over the wisdom of conducting research that has the potential to help as well as harm, scientists reported Wednesday that they had engineered a mutant strain of [H5N1] bird flu that can spread easily between ferrets -- a laboratory animal that responds to flu viruses much as people do," the Los Angeles Times (Brown, 5/3).

Presence of fetal cells is a double-edged sword for women

For the first time, scientists have found what could be a causative link between the concentration of circulating Y-chromosome fetal cells in women who gave birth to children of either sex and their risk of later developing breast cancer and colon cancer.

Malfunctioning single proteins cause disruptions in neuronal junctions leading to autism

Malfunctioning single proteins can cause disruptions in neuronal junctions leading to autistic forms of behavior. A current study, published in the scientific journal Nature, comes to this conclusion after examining genetically altered mice.

Potential breast cancer patients for new immune-targeting therapies

Breast cancer patients whose tumors express high levels of genes related to immune response are more likely to have their tumor completely eradicated by pre-operative chemotherapy compared to patients with low expression of these genes, Belgian researchers report at the 4th IMPAKT Breast Cancer Conference in Brussels, Belgium.

New analysis may help identify breast cancer patients who will benefit from immune suppressant

A new analysis may help doctors identify breast cancer patients who will benefit from treatment with the immune suppressant drug everolimus, say French researchers at the 4th IMPAKT Breast Cancer Conference in Brussels, Belgium.

Study affirms necessity of heart rehabilitation programs for cardiac patients

University of Granada researchers affirm that it is "essential" that heart rehabilitation programs aimed at patients with any heart disease are established and provided to cardiac patients. The study included a sample of 200 patients suffering from heart disease.

Helmets a useful addition but not substitutes for shelter in tornadoes: CDC says

Tornadoes often cause death or bad injuries more often than not in the head. Many safety advocates have started telling people to wear helmets when they hunker down during tornado warnings.

One of the controversial avian flu studies published in full finally

After endless debates and controversies on whether two studies that demonstrated how bird flu, also known as avian H5N1 influenza, or avian flu, should be published, one of them has appeared in the latest issue of the journal Nature in its entirety. The two studies aimed for publication in journals Nature and Science show how the bird flu virus could become transmissible from mammal-to-mammal; as humans are mammals, the same would apply to humans.

Aspirin versus warfarin for heart failure patients

In a new study on more than 2,000 patients, published in the New England Journal of Medicine, researchers found that aspirin was as effective as the commonly prescribed drug warfarin. It said each drug had risks, but they had similar benefits overall.

SPECT/CT can change clinical management of thyroid cancer

The use of single positron emission computed tomography (SPECT)/computed tomography (CT) has been reported to change clinical management in a significant number of thyroid cancer patients according to research presented in the May issue of The Journal of Nuclear Medicine.

Researchers identify new functions of cohesin SA1 that are relevant for cancer and CdLS

Cohesin is a ring-shaped protein complex involved in the spatial organization of the genome and in mitotic chromosome structure. Vertebrate somatic cells have two versions of cohesin that contain either SA1 or SA2, but their functional specificity has been largely ignored. Researchers of the Spanish National Cancer Research Centre (CNIO) under the direction of Ana Losada have identified new functions of cohesin SA1 that are relevant for two human diseases, cancer and Cornelia de Lange Syndrome.
