Chemo Patients Benefit From Hair Circadian Clock
2013-05-21 10:00:16

redOrbit Staff & Wire Reports - Your Universe Online The discovery that mouse hair operates on a circadian clock has given researchers hope that cancer radiotherapy and chemotherapy could be scheduled later in the day in order to minimize hair loss in patients. According to the study, which was published online Monday in the Proceedings of the National Academy of Sciences (PNAS), experts from the Salk Institute for Biological Studies, the University of Southern California (USC) and...

Depression Can Alter A Person’s Circadian Clock At The Cellular Level
2013-05-14 07:16:55

redOrbit Staff & Wire Reports - Your Universe Online The circadian clock rhythms that help govern biological, hormonal and behavioral patterns in the human body are altered at the cellular level in people suffering from depression, according to new research published in the Proceedings of the National Academy of Sciences (PNAS). According to the researchers, every cell in the human body operates on a 24-hour clock, with the brain serving as the timekeeper that helps keep things...

Brett Smith for redOrbit.com - Your Universe Online A new study on glowing bacteria found within Hawaiian bobtail squid could change the way scientists look at symbiotic microorganisms. The study, which was recently published in the journal mBio, showed the Vibrio fischeri bacteria in the squid´s light organ not only camouflage the animal at night — the bacteria also influence a gene that entrains, or synchronizes, the cephalopod´s circadian rhythms. "To our...

Pineal Gland
2013-04-30 10:31:18

The pineal gland, also called the epiphysis cerebri, is an endocrine organ located in the brain. Its primary function is to regulate the sleep cycle and influence sexual development. It is a reddish-gray glandular structure that forms the roof of the third ventricle in the brain, between the two lateral ventricles, tucked in a groove near the thalamic bodies. Its body is relatively the size of a grain of rice; it’s shaped like a pine cone and has an infindibular stalk projecting from it....
