Research leads to healthful strategies for re-setting the body's clock
March 23, 2006Everyone is equipped with a biological clock, a region in the brain the size of a corn kernel, which dictates our sleep-wake cycles, and plays a major role in our physical and mental health. Pioneering research conducted by Kent State professor Dr. David Glass has shown the body's clock can be re-set - good news for people who work swing shifts, experience jet lag or take anti-depressants.
Glass, known internationally as the first researcher to measure serotonin release from the brain's biological clock region, has become the first to extract, identify and measure a neuropeptide crucial to the regulation of the body's clock. Glass found the neuropeptide can be used to re-set the biological clock when it has been disrupted.

Biological Clock Current Events and Biological Clock News RSSJava and nighttime jobs don't mix: study
Night-shift workers should avoid drinking coffee if they wish to improve their sleep, according to research published in the journal Sleep Medicine.
The food-energy cellular connection revealed
Our body's activity levels fall and rise to the beat of our internal drums-the 24-hour cycles that govern fundamental physiological functions, from sleeping and feeding patterns to the energy available to our cells.
U-M discovery about biological clocks overturns long-held theory
University of Michigan mathematicians and their British colleagues say they have identified the signal that the brain sends to the rest of the body to control biological rhythms, a finding that overturns a long-held theory about our internal clock.
WUSTL research finds individual cells isolated from the biological clock can keep daily time, but are unreliable
Alexis Webb enters a small room at Washington University in St. Louis with walls, floor and ceiling painted dark green, shuts the door, turns off the lights and bends over a microscope in a black box draped with black cloth. Through the microscope, she can see a single nerve cell on a glass cover slip glowing dimly.
Chemotherapy for breast cancer is associated with disruption of sleep-wake rhythm in women
A study in the Sept.1 issue of the journal Sleep shows that the sleep-wake activity rhythms of breast cancer patients are impaired during the administration of chemotherapy.
Biological clocks of insects could lead to more effective pest control
Researchers at Oregon State University have discovered that the circadian rhythms or biological "clocks" in some insects can make them far more susceptible to pesticides at some times of the day instead of others.
Biological Timekeeper Studies Reveal New Temperature Regulator and Track Clock Protein across a Day
Dartmouth Medical School geneticists have made new inroads into understanding the regulatory circuitry of the biological clock that synchronizes the ebb and flow of daily activities.
Balancing hormones may help prevent preterm births
The relationship between two different types of estrogen and a hormone produced in the placenta may serve as the mechanism for signaling labor, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).
Children of older fathers perform less well in intelligence tests during infancy
Children of older fathers perform less well in a range of cognitive tests during infancy and early childhood, according to a study published this week in the open-access journal PLoS Medicine. In contrast, the study finds that children with older mothers gain higher scores in the same tests - designed to measure the ability to think and reason, including concentration, learning, memory, speaking and reading skills.
School-based intervention is a promising model for improving adolescent sleep habits
A study in the March 1 issue of the journal SLEEP shows that a school-based sleep intervention is a promising model for addressing adolescent sleep problems, given its high retention rate, cost-effectiveness and potential for promoting healthy sleep knowledge and practice.

The Male Biological Clock: The Startling News About Aging, Sexuality, and Fertility in Men by Harry Fisch (Author), Stephen Braun (Contributor) Part fertility guide, part owner's manual to the male reproductive system, The Male Biological Clock attempts to ditch some of the numerous existing myths about men's roles in pregnancy while introducing up-to-date medical research on hormones and health. In modern culture, the words "male" and "biological clock" aren't typically seen together, but Dr. Harry Fisch has news: after the age of 35, men have increased rates of infertility, can contribute to the likelihood of a miscarriage, and are more likely to father a child with Down syndrome. Blunt and informative, the book starts off with a basic introduction to male anatomy, and goes into greater detail on the subject of testosterone. A number of simple graphs and charts are included, as well as detailed weighing of pros and... |

What Every Woman Should Know About Fertility and Her Biological Clock by Cara Birrittieri (Author) Until now, there has been little practical advice on what women can do about ticking biological clocks. What Every Woman Should Know About Her Biological Clock is the first book to explore a woman's reproductive life span completely, from beginning to end. Based on Cara Birrittieri's own experience of running up against a slowing biological clock, she shows women for the first time how to "tell what time it is" with a simple blood test that gives them a peek at the state of their ovaries. What Every Woman Should Know About Her Biological Clock will: * Show women how ovarian reserve tests can monitor the biological clock. * Give women an evolutionary explanation for such an unforgiving clock. * Offer a method to calculate the duration of the biological clock. * Explain how birth... |

Biological Clocks - Clockwork Genes: Discoveries in Biological Time Also With: Dr. Michael Rosbash (Narrator), Dr. Joseph S. Takahashi (Narrator) Researchers are making groundbreaking discoveries in understanding the molecular basis of circadian clocksthe internal timekeepers that govern fluctuations in behavior and physiology on a 24-hour cycle. In four lectures, Dr. Michael Rosbash and Dr. Joseph S. Takahashi explain what circadian clocks are, how they work, and what relevance this knowledge might have for human health. They describe the techniques that led to their discoveries of the genes, proteins, and other components that make up these complex biological pacemakers. The scientists use animations to illustrate complex concepts and answer questions from their student audience. DVD includes detailed chapter search by scientific topic, direct access to animations, English subtitles, speakers biographies and interviews, and... | |
