by University of Delaware NAD+ and NADH concentrations in NEVs and change–change correlations with insulin signaling proteins. (a) Concentration of NAD+ after 6 weeks of oral nicotinamide riboside (NR) supplementation was significantly higher in NEVs when compared to placebo (n = 10, p = 0.0092, paired ttest), while NADH remained relatively unchanged (n = 22, p = 0.215,...
Your brain could be controlling how sick you get — and how you recover
Diana Kwon Illustration by Dalbert B. Vilarino Hundreds of scientists around the world are looking for ways to treat heart attacks. But few started where Hedva Haykin has: in the brain. Haykin, a doctoral student at the Technion — Israel Institute of Technology in Haifa, wants to know whether stimulating a region of the brain...
Lifelong bachelors face poorest prognosis with heart failure
AMERICAN COLLEGE OF CARDIOLOGY Men who never married were more than twice as likely to die within about five years after a heart failure diagnosis compared with women of any marital status or men who were previously married, according to a study presented at the American College of Cardiology’s Annual Scientific Session Together With the...

A human interactome to prioritise drug discovery
EUROPEAN MOLECULAR BIOLOGY LABORATORY IMAGE: A HUMAN INTERACTOME TO PRIORITISE DRUG DISCOVERY CREDIT: KAREN ARNOTT/EMBL-EBI Scientists at Open Targets, EMBL’s European Bioinformatics Institute (EMBL-EBI), and GSK are revealing the shared basis of diseases using a map of interacting human proteins. By helping to understand how biological processes affect human traits and diseases, this work will...
Researchers: “We have miscalculated for decades – half of an insulin dose may not work as expected”
UNIVERSITY OF COPENHAGEN – FACULTY OF SCIENCE IMAGE: FREJA BOHR CREDIT: UNIVERSITY OF COPENHAGEN New research suggests that a large portion of a diabetic’s insulin dose is unlikely to work as expected. University of Copenhagen researchers have discovered that we have miscalculated insulin behavior for many years. The discovery provides a tool for developing better insulin preparations that are...
Skipping breakfast may compromise the immune system

Genetic links between migraine and blood sugar levels confirmed
by Queensland University of Technology The forest plot demonstrates the odds ratios (ORs) and 95% confidence intervals (CIs) for MR analyses examining the causal effects of glycemic traits on migraine (A) and headache (B). IVW Inverse variance weighted was employed as the primary analysis, GSMR Generalized summary data-based Mendelian Randomisation was used as a sensitivity...
