Fri, 06/23/2017 - 12:53
Scientists from the University of Birmingham have discovered the link between increased male hormones and metabolic complications such as diabetes and fatty liver disease in patients with polycystic ovary syndrome.

Intensive blood pressure lowering reduces CKD patients' risks of heart disease and death

Fri, 06/23/2017 - 11:43
Results from a recent clinical trial indicate that intensive blood pressure lowering reduces chronic kidney disease patients' risks of dying prematurely or developing cardiovascular disease. The findings appear in an upcoming issue of the Journal of the American Society of Nephrology.

Fri, 06/23/2017 - 11:38
This study investigated whether children whose mothers had an alcohol-related disorder would be at risk of early-life contact with the justice system, which can lead to many negative outcomes across an individual's life span.

New biomarker assay improves detection, assessment of neuroblastoma

Fri, 06/23/2017 - 11:27
Investigators at The Saban Research Institute of Children's Hospital Los Angeles have developed and tested a new biomarker assay for quantifying disease and detecting the presence of neuroblastoma even when standard evaluations yield negative results for the disease.

Study provides evidence that cortical targets could enhance motor function after spinal cord injury

Fri, 06/23/2017 - 11:04
Monica A. Perez, P.T., Ph.D., Associate Professor, Department of Neurological Surgery and The Miami Project, and colleagues, recently published A novel cortical target to enhance hand motor output in humans with spinal cord injury in the June issue of Brain that provides the first evidence that cortical targets could represent a novel therapeutic site for improving motor function in humans paralyzed by spinal cord injury (SCI).

Human colon organoids fill gap in effectively modeling common GI diseases

Fri, 06/23/2017 - 08:12
Scientists used human pluripotent stem cells to generate human embryonic colons in a laboratory that function much like natural human tissues when transplanted into mice, according to research published June 22 in Cell Stem Cell.

Which animal is most likely to spread the latest plague?

Fri, 06/23/2017 - 08:02
There are a large number of infections that are borne and carried by animals and spread to humans. These are called zoonotic diseases wherein the microbe or pathogen jumps from one species of the animals to another. Now a new study has ranked mammals based on the risk they pose to humans in terms of spreading infectious diseases to humans.
