OTIMISMO
*Artigo enviado para ZH na última semana e não publicado. Dedico-o aos meus AMICOR* *OTIMISMO* *Aloyzio Achutti.

Nós médicos também temos tendência de contemplar todo mundo como ... mais »
Encontros
*Gratos encontros de fim de ano e princípio de novo, 2015.* Minhas irmãs Lia Maria e Maria Helena, deram-nos o prazer de passar conosco o Natal e a virada do Ano. Voltaram hoje para Santa Maria, onde moram. Mais visitas tivemos: Luiz Maria Yordi que não mora mais em Porto Alegre, mas em Dom Pedrito, em sua fazenda. Colando abaixo uma foto de registro de sua passagem. Hoje, estavam de aniversário meu filho Luiz Eduardo e seu filho Eduardo Bellardinelli Achutti. Também tenho fotos para lembrar o feliz encontro celebrado com um churrasco reunindo a família.

everolimus (AKA RAD001)
A step toward a potential anti-aging drugDecember 29, 2014 Everolimus, AKA RAD001 (credit: Fvasconcellos/public domain) According to a new study published in *Science Translational Medicine*, researchers have tested a potential anti-aging drug called everolimus (AKA RAD001) — an analog (version) of the drug rapamycin (sirolimus)*. In previous research, rapamycin extended the life span of mice by 9 to 14%, even when treatment was initiated late in life, and it improved a variety of aging-related conditions in old mice, including tendon stiffening, cardiac dysfunction, cognitive decline,... mais »
ancient stress response
Resveratrol found to activate ancient stress response and at 1,000 times lower doses December 30, 2014 [image: 400px-Glass_of_red_wine] Scientists at The Scripps Research Institute (TSRI) have found that a fundamental new mechanism for the known beneficial effects of resveratrol — the grapes and red-wine ingredient once touted as an elixir of youth: it powerfully activates an evolutionarily ancient stress response in human cells. “This stress response represents a layer of biology that has … more…
protein without genetic instructions

DOI: 10.1126/science.1260825. Photograph: DOI: 10.1126/science.1260825. These data suggest there is a relationship between risk of cancer and number of cell divisions. But it says nothing about the proportion of cancers due to cell division.
