A long-standing mystery is why fast-growing cells, like cancer cells and immune cells, rely on a seemingly inefficient form of metabolizing glucose to power their activities. In a new study, scientists now offer a compelling solution. from Top Health News -- ScienceDaily https://ift.tt/367LlMa via IFTTT

Scientists have created a highly detailed map of skin, which reveals that cellular processes from development are re-activated in cells from patients with eczema and psoriasis inflammatory skin diseases. The study offers potential new drug targets for treating these painful skin diseases and provides a new understanding of inflammatory disease. The research could also provide a template for regenerating healthy skin in the laboratory. from Top Health News -- ScienceDaily https://ift.tt/2Y7UcsO via IFTTT

Treatment options for many types of cancers remain limited, due partly to the in vitro tools used to model cancers and that results from animal studies do not always translate well to human disease. These shortcomings point to a clear need for a better, patient-specific model. Researchers suggest bioengineered microscale organotypic models can address this need. from Top Health News -- ScienceDaily https://ift.tt/2Mmo81x via IFTTT

More people could be protected from life-threatening rabies thanks to an agile approach to dog vaccination using smart phone technology to spot areas of low vaccination coverage in real time.

Numerous natural products are awaiting discovery in all kinds of natural habitats. Especially microorganisms such as bacteria or fungi are able to produce diverse natural products with high biomedical application potential in particular as antibiotics and anticancer agents. Researchers have isolated red yeast of the species Rhodotorula mucilaginosa from a deep-sea sediment sample and analyzed for its genome and chemical constituents. The scientists succeeded in demonstrating its anticancer and antibacterial effects. from Top Health News -- ScienceDaily https://ift.tt/3a1S2QS via IFTTT

For the study 40 infants of women diagnosed with postpartum depression were matched with 40 infants of non-depressed mothers on infant age, gender and socioeconomic status. The mothers with postpartum depression received nine weeks of group CBT. The infants were all tested before the treatment and nine weeks later, including a questionnaire on the infant behaviour completed by the mother and her partner. from Top Health News -- ScienceDaily https://ift.tt/365n7C5 via IFTTT

A new study of Type 2 diabetes (T2D) in Japanese populations has uncovered a previously uncharacterized genetic variant that puts male carriers at greater risk for the disease, as well as the mechanism by which it does so. The impact of the variant was most pronounced in sedentary men; those with the variant had a 65% greater rate of T2D than sedentary men without it. from Top Health News -- ScienceDaily https://ift.tt/39RX1DU via IFTTT
