  • RESULT Chronic disruption of circadian rhythm can increase incidences of chronic diseases like obesity, diabetes, heart disease, cancer and depression Our subjects lost 3.8% average weight in 3-month pilot trial, measured after 1 year. (slideshare.net)
  • This issue is compounded during winter months when days are shorter and a majority of time is spent inside, leaving room for circadian disruption and impacts on sleep patterns and mood. (constantcontact.com)
  • Advanced lighting design can minimize circadian disruption by providing for high illuminances during the day and low illuminances at night befitting the requirements of a given space. (constantcontact.com)
  • different circadian
  • The adaptive fitness test was done by mixing cyanobacterial strains that express different circadian properties (i.e., rhythmicity vs. arhythmicity, different periods, etc.) and growing them in competition under different environmental conditions. (wikipedia.org)
  • We tested the adaptive significance of circadian programming by measuring the relative fitness under competition between various strains of cyanobacteria expressing different circadian periods. (pnas.org)

  • The molecular response of an organism -- be it mouse or man -- to pathogenic invasion is controlled by circadian rhythms, researchers found. (medpagetoday.com)
  • People have suspected that our cells' response to insulin had a circadian cycle, but we are the first to have actually measured it," noted Owen McGuinness , a professor of molecular physiology and biophysics at Vanderbilt, in the statement. (redorbit.com)
  • genes
  • New research that involved the examination of thousands of genes from nearly 150 human brains shows the circadian rhythm of gene activity changes with aging. (psychcentral.com)
  • The researchers next plan to explore the function of the brain's circadian-rhythm genes in lab and animal models, as well as see if they are altered in people who have psychiatric or neurological illnesses. (psychcentral.com)
  • Interacting positive and negative feedback loops at the transcriptional and post-translational level ensure tight control over transcription factors regulating expression of the appropriate genes required during circadian days or nights. (qiagen.com)

  • It's just a worm, a tiny soil-dwelling nematode worm -- but the implications are big for biomedicine and circadian biology as shown in a recent study authored by University of Nevada, Reno researcher Alexander van der Linden. (scienceblog.com)
  • Circadian Rhythms opens with chapters that lay the fundamental groundwork on circadian rhythm biology. (wiley.com)
  • Clockwork
  • An appropriate way to determine the adaptive significance of circadian programs would be to examine the reproductive fitness of mutants whose circadian clockwork is altered. (pnas.org)
  • strains
  • Strains that had a circadian period similar to that of the light/dark cycle were favored under competition in a manner that indicates the action of soft selection. (pnas.org)
  • light
  • The term circadian derives from the Latin circa (about) diem (a day), since when taken away from external cues (such as environmental light), they do not run to exactly 24 hours. (wikipedia.org)
  • Bright light therapy is designed to reset a patient's circadian rhythm to a desired pattern. (hopkinsmedicine.org)
