Improvement persists for more than a year. About 80% of patients with moderate to severe psoriasis saw their disease completely or almost completely cleared with a new drug called ixekizumab, according to 3 large, long-term clinical trials led by NW Medicine. “This group of studies not only shows very high and consistent levels of safety and efficacy, but also that the great majority of the responses persist at least 60 weeks,” said Dr. Kenneth Gordon.

Affecting about 3% of the world’s population, psoriasis is an immune-mediated inflammatory disease that causes itchy, dry and red skin. It is also associated with an increased risk for depression, heart disease and diabetes, among other conditions...

Even moderate zinc deficiency is bad for digestion. The trace element zinc has an impact on the essential metabolic functions of most living organisms. New research carried out by the Chair of Animal Nutrition at the Technical University of Munich (TUM) has found that reduced zinc impairs digestion, albeit without any typical symptoms such as skin problems or fatigue. Hence, short-term zinc deficiency in the diet should be avoided.

The test series established even slight zinc deficiency in an animal’s diet impedes pancreatic digestive activity even at an early stage.

Scientist Brugger charted a new path since all previous studies had compared the functions of animals with clinical zinc deficiency to those of animals that had adequate amounts of this trace element in their bodies...

Stress during pregnancy has been linked to several conditions, including some instances of autism spectrum disorder. Now, researchers at the Uni of Missouri School of Medicine have observed a variant of a stress-sensitive gene and exposure to stress during pregnancy among two groups of mothers of children with autism. The researchers believe the finding could be a step toward helping identify women who have greater risks for having children with autism when exposed to stressors during a specific time window during pregnancy.

“Autism was thought to be largely a genetic disorder, but previous research has shown that environmental influ...

Exercise-induced ROS activates Nrf2, which then translocates into the nucleus to increase the expression of antioxidant enzymes. Antioxidant response element (ARE), carbon monoxide (CO), Glutathione peroxidase (GPx), Glutathione S-transferase (GST), Heme oxygenase-1 (HO-1), Kelch-like ECH-associated protein 1 (Keap1), NAD(P)H quinone oxidoreductase-1 (NQO-1), and nuclear factor erythroid 2-related factor 2 (Nrf2).

If you’re an older adult, a 30 min workout may not be as effective, even at the cellular level, as it was when you were younger. According to a new study, age may play a significant role in a cell’s ability to respond to that activity. In the study, a group of men 18 to 30 yo were tested against a group of older men 55 years and older...
