LONDON – Initiating antiretroviral treatment (ART) as soon as infants who are positive for HIV-1 infection are born has significant protective effects, with fewer viral reservoir cells and improved immune system development, according to new research.

A new web-based tool allowing rapid in silico prediction of the ability of candidate antibiotics to accumulate in Gram-negative bacteria should enable subsequent prioritization of new compounds for synthesis and further evaluation, U.S. researchers reported Nov. 18, 2019, in Nature Microbiology.

Many pediatric brain tumors occur in specific time windows of childhood. For that reason, such tumors are thought to have their origins in faulty prenatal development. Scientists at McGill University and the University of Toronto have gained new insights into what those faults are in several pediatric tumors.

MELBOURNE, Australia – Researchers at the Murdoch Children’s Research Institute in Melbourne are pushing the boundaries on creating kidney tissue from stem cells. For more than two decades, Melissa Little and her team at Murdoch have investigated the molecular and cell development basis of kidney disease and the potential for regeneration. The team has developed approaches for directing the differentiation of human pluripotent stem cells to human kidney organoids and is applying that knowledge to disease modeling, drug screening, cell therapy and tissue engineering.
