The World Health Organization has lifted its global health emergency designation for the Zika virus, prompting concerns from some public health experts that the move could stall investments on research and preparedness efforts. However, the CDC said that the WHO's declaration doesn't reduce the urgency of developing Zika vaccines and diagnostics or of understanding its health risks on fetuses and infants.
Why Platform Matters When Choosing an ERP System In order to survive, grow, and compete in the digital age, organizations need an ERP that is highly flexible and able to adapt.

Nancy Millar, whose son donated his tissue and organs, met the former firefighter whose face transplant still bears the chickenpox scar she kissed so many times on her child's forehead. Before the transplant, Pat Hardison had more than 70 surgeries to rebuild features of his face using skin grafts and prosthetic ears. And in addition to his organs and face, David Rodebaugh, Millar's son, donated his corneas, bone and skin tissue.
Eleven of 13 Brazilian infants with congenital Zika syndrome and normal head circumference at birth developed microcephaly in the following months. A report in the CDC's Morbidity and Mortality Weekly Report said the infants had a range of symptoms of congenital Zika syndrome, including muscle and joint problems and difficulty moving and swallowing.
Sexually transmitted Zika virus might go undetected in women due to a delayed immune response in the vagina, allowing the virus more time to infect the fetus if the woman is pregnant, according to a mouse study published in the Journal of Experimental Medicine. Mice infected vaginally did not mount an immune response until about a week after infection, when the virus had spread to lymphoid tissues, and though the mice later cleared the virus, traces remained in the vagina.
A study in the Annals of Internal Medicine found nine cases where blood tests for the Zika virus came back negative but the virus was found in other fluids, suggesting the need for global, standardized diagnostic testing methods, according to researchers. Travel advisories should continue because outbreaks are still ongoing in the South Pacific and Southeast Asia, said public health researcher Dr. Davidson Hamer of Boston University.
Injections of MHC-matched induced pluripotent stem cells in monkey models of myocardial infarction resulted in no evidence of acute graft rejection, no tumor growth and greater heart contractile function, according to a study in the journal Nature. The transplanted cardiomyocyte differentiated iPSCs, following placement in the infarct and border zones of the induced MI, beat spontaneously and responded to caffeine.
