Scripps Research Institute study suggests expanding the genetic alphabet may be easier than previously thoughtJune 6, 2012 (Credit: iStockphoto) A new study led by scientists at The Scripps Research Institutesuggests that the replication process for DNA — the genetic instructions for living organisms that is composed of four bases (C, G, A and T) — is more open to unnatural letters than had previously been thought. An expanded “DNA alphabet” could carry more information than natural DNA, potentially coding for a much wider range of molecules and enabling a variety of powerful applica... mais »

Toxic Shock from Strep

Aloyzio AchuttiemAMICOR - 1 dia atrás
Toxic Shock from Strep: a 'Lightning Strike' By Todd Neale, Senior Staff Writer, MedPage Today Published: June 08, 2012 In rare cases, the bacteria responsible for causing strep throat -- group A *Streptococcus*-- can penetrate beyond the superficial surfaces of the body and lead to necrotizing fasciitis, toxic shock syndrome, and even death. But, but because most strep infections are treated easily with antibiotics, there are challenges in identifying which patients will progress to the more severe invasive infections, according to Rodney Willoughby, MD, a pediatric infectious diseas... mais »

Brain Plasticity

Aloyzio AchuttiemAMICOR - 2 dias atrás
The Adolescent Brain "The idea that the brain is somehow fixed in early childhood, which was an idea that was very strongly believed up until fairly recently, is completely wrong. There's no evidence that the brain is somehow set and can't change after early childhood. In fact, it goes through this very large development throughout adolescence and right into the 20s and 30s, and even after that it's plastic forever, the plasticity is a baseline state, no matter how old you are. That has implications for things like intervention programs and educational programs for teenagers."/.../

Transplante Cardíaco

Aloyzio AchuttiemAMICOR - 3 dias atrás
*Caros AMICOR,* *Este artigo, publicad na ZH de hoje, foi escrito por um primo meu, filho de um de meus tios médicos - Ary Cechella (1922-1977) - nascido quando eu estava nos primeiros anos da Faculdade. Lembro-me quando ele veio a Porto Alegre trazendo o filho nos braços, com menos de um ano de vida, com dispnéia e o diagnóstico fora de pneumonia. Como ele não melhorasse com os tratamentos, resolveu ministrar-lhe Digitaline Nativelle, com o que ele ficou bem, desenvolveu-se, fez curso superior de educação física e foi atleta, campeão gaúcho de natação. Submeteu-se a um transplante c...mais »

Polymer pills turn out "lytes" in chronic HF with renal disease *B**elgrade, Serbia *- Could plastics at least partly take over the job of diuretics in chronic heart failure? Patients with advanced HF and renal dysfunction who daily swallowed a handful of capsules containing an electrolyte- and fluid-binding polymer showed meaningful gains in symptom and functional status over eight weeks, according to researchers from the small study [1,2].
