Stem cells used to model infant birth defect

Welcome once more to ItexMall Health and Fitness, where you can enjoy reading another fascinating snippet of Health news right here:

Researchers recently discovered that infantile hemangiomas originate from stem cells, and have used these stem cells to better understand this tumor in the laboratory. They show that steroids target hemangioma stem cells specifically, reveal their mechanism of their action and suggest other possible ways to halt and shrink hemangiomas.

Environment may impact apes’ ability to understand declarative communication, study suggests

Welcome once more to ItexMall Health and Fitness, where you can enjoy reading another fascinating snippet of Health news right here:

Bonobos and chimpanzees that had been reared in socio-linguistically rich environments (i.e., lots of opportunities for complex communicative interactions with humans) performed significantly better in the pointing, vocalizing, and pointing-and-vocalizing conditions of an object-choice task than did chimpanzees that had been reared in standard laboratory settings. These results indicate that apes may have the potential for understanding declarative communication and this potential may be achieved in specific environments.

‘Flying vaccinator’: Can genetically engineered mosquitoes provide a new strategy against malaria?

Welcome once more to ItexMall Health and Fitness, where you can enjoy reading another fascinating snippet of Health news right here:

Mosquitoes transmit infectious diseases to millions of people every year, including malaria for which there is no effective vaccine. New research reveals that mosquito genetic engineering may turn the transmitter into a natural “flying vaccinator,” providing a new strategy for biological control over the disease.

Shutting out soft tissue cancers in the cold

Welcome once more to ItexMall Health and Fitness, where you can enjoy reading another fascinating snippet of Health news right here:

Cryotherapy, an interventional radiology treatment to freeze cancer tumors, may become the treatment of the future for cancer that has metastasized in soft tissues (such as ovarian cancer) and in bone tumors. Such patients are often not candidates for surgery and would benefit from minimally invasive treatment, say researchers.

Urban CO₂ domes increase deaths, poke hole in cap-and-trade proposal

Welcome once more to ItexMall Health and Fitness, where you can enjoy reading another fascinating snippet of Health news right here:

In the first study ever done on the local health effects of the domes of carbon dioxide that develop above cities, researchers found that the domes increase the local death rate. The result provides a scientific basis for regulating CO₂ emissions at the local level and points out a significant oversight in the carbon dioxide “cap-and-trade” proposal that was passed by the House of Representatives in June 2009.
