Sentences with phrase «altered circadian rhythms»

People with poor sleep habits and subsequent altered circadian rhythms have increased rates of leptin resistance.

This gives an insight into how the biological clock is regulated by light and could open up new therapeutic opportunities to help restore altered circadian rhythms through the eye.

«For more than 50 years, there's been evidence that there's something wrong with circadian rhythms in people with bipolar disorder, but there has been a huge gap in terms of what we understand about their brains and how altered circadian rhythms are contributing to their symptoms,» noted Pantazopoulos, lead author of the study.

Fuse suggests this might be due to differences in pheromone signaling when the flies select their mates, or to altered circadian rhythms of mating or sleep behaviors.

The first fly mutants to show altered circadian rhythms were identified in the early 1970s by Ron Konopka and Seymour Benzer of the California Institute of Technology.

Tumor cells use the unfolded protein response to alter circadian rhythm, which contributes to more tumor growth, Hollings Cancer Center researchers at the Medical University of South Carolina (MUSC) find.

Animals with gene mutations that significantly alter their circadian rhythms have shorter life spans, and circadian rhythm sleep disorders in humans can have profoundly negative effects, including increased risk for obesity, depression, cardiovascular disease and cancer.

Blue light is the type of light color your brain associates with daytime, and exposing your brain to excessive amounts of this type of light in the nighttime hours alters your circadian rhythms and your body's natural melatonin production.

Not exact matches
