Stem cell transplant from young to old can heal stomach ulcers
Bethesda, MD (June 16, 2016) -- Basic and translational research paves the way for breakthroughs that can ultimately change patient care. Three new studies from Cellular and Molecular Gastroenterology and Hepatology (CMGH) -- AGA's basic and translational open-access journal -- provide a glimpse into future treatment strategies for stomach ulcers, inflammatory bowel disease and alcoholic liver disease. Please find summaries below. To speak with the journal authors, please email...

Butterfly mimicry through the eyes of bird predators
In the natural world, mimicry isn't entertainment; it's a deadly serious game spanning a range of senses - sight, smell and hearing. Some of the most striking visual mimics are butterflies. Many butterflies become noxious and unpalatable to predators by acquiring chemical defences from plants they ingest as caterpillars. Other butterflies mimic the 'aposematic' or warning colouration and conspicuous wing patterns of these toxic or just plain foul-tasting butterflies. In a new study, scientists...

A key protein is discovered as essential for malaria parasite transmission to mosquitos
Two teams have independently discovered that a single regulatory protein acts as the master genetic switch that triggers the development of male and female sexual forms (termed gametocytes) of the malaria parasite, solving a long-standing mystery in parasite biology with important implications for human health. The protein, AP2-G, is necessary for activating a set of genes that initiate the development of gametocytes -- the only forms that are infectious to mosquitos. The research also gives...

Fetal mice with Zika infection get microcephaly
Mouse fetuses injected with the Asian Zika virus strain and carried to term within their pregnant mothers display the characteristic features of microcephaly, researchers in China report May 11 in Cell Stem Cell. As expected, the virus infected the neural progenitor cells, and infected brains reveal expression of genes related to viral entry, altered immune response, and cell death. The authors say this is direct evidence that Zika infection causes microcephaly in a mammalian animal...

Yaşlanmayan Canlı ; Turritopsis Nutricula
Dr John Wu, M.D., founder of NAIMION, and Turritopsis Nutricula, the youth reverting jellyfish. Since 2010, Dr. John Wu has been intensely studying the cellular transdifferentiation that occurs during the youth reverting cycle of the Turritopsis. Using it as a research model, Dr. John discovered and perfected 14 active factors that can significantly improve skin. These "QKK Factors" work synergistically in transforming the appearance of blemished wrinkled skin into a supple, tight, and...

Evrim'in son ve en büyük laboratuvarı olan Madagaskar için zaman tükeniyor
Dünyadaki hiçbir yerde bulunmayan binlerce bitkiye ev sahipliği yapan benzersiz bir evrim evidir. Bununla birlikte, Madagaskar'ın özel ağaçları, onlarca tür nadir lemur ve diğer hayvanların habitatlarını ve yemeklerini sağlar. İklim değişikliği ve tarımın yaygınlaşması sonucu felaket yıkımına maruz kalıyorlar.
