Dawn triggers basic biological changes in the waking human body. As the sun rises, so does heart rate, blood pressure and body temperature. The liver, the kidneys and many natural processes also begin shifting from idle into high gear. Then as daylight wanes and darkness descends, these processes likewise begin to subside, returning to their lowest levels again as we sleep.

These internal biological patterns are tightly linked to an external cosmic pattern: the earth’s rotation around the sun once every 24 hours. This endless loop of light and darkness and the corresponding synchrony of internal and external clocks, are called circadian rhythms, from “circa diem,” Latin for “approximately a day.” Circadian rhythms influence almost all living organisms, from bacteria to algae, insects, birds and, as is increasingly understood by science, humans beings.

Measuring Microbes Makes Wetland Health Monitoring More Affordable, Says MU Researcher

Understanding microbe communities could improve wetland wastewater treatment systems

COLUMBIA, Mo. – Wetlands serve as the Earth’s kidneys. They filter and clean people’s water supplies while serving as important habitat for many species, including iconic species like cattails, cranes and alligators. Conventional ecosystem health assessments have focused on populations of these larger species. However, the tiny, unseen creatures in the wetlands provided crucial indicators of the ecosystems’ health in a study by University of Missouri Associate Professor of Engineering Zhiqiang Hu and his team. Using analysis of the microbiological health of wetlands is cheaper and faster than traditional assessments, and could lead to improvements in harnessing natural processes to filter humans’ wastewater.

“During road and building construction, engineers must sacrifice wetlands to development, but laws dictate that these lost wetlands be compensated for by establishing a wetland somewhere else,” said Hu. “Our research could be applied to both monitor the success of these compensation wetlands and guide conservationists in inoculating new engineered ecosystems with the correct types of microorganisms.” (more…)

Growing Market for Human Organs Exploits Poor

EAST LANSING, Mich. — A Michigan State University anthropologist who spent more than a year infiltrating the black market for human kidneys has published the first in-depth study describing the often horrific experiences of poor people who were victims of organ trafficking.

Monir Moniruzzaman interviewed 33 kidney sellers in his native Bangladesh and found they typically didn’t get the money they were promised and were plagued with serious health problems that prevented them from working, shame and depression. (more…)

Scientists Pinpoint How Vitamin D May Help Clear Amyloid Plaques Found in Alzheimer’s

A team of academic researchers has identified the intracellular mechanisms regulated by vitamin D3 that may help the body clear the brain of amyloid beta, the main component of plaques associated with Alzheimer’s disease.

Published in the March 6 issue of the Journal of Alzheimer’s Disease, the early findings show that vitamin D3 may activate key genes and cellular signaling networks to help stimulate the immune system to clear the amyloid-beta protein. (more…)

New Drug Aids Gout Patients Not Helped By Standard Treatments

Pegloticase, a modified porcine enzyme, can produce significant and sustained clinical improvements in two out of five patients with chronic gout that is resistant to conventional therapies, researchers report in the Aug. 17 issue of JAMA.

In two controlled clinical trials, pegloticase rapidly lowered high levels of uric acid, the biochemical abnormality in gout, and kept it in the normal range for six months or more in 42 percent of patients receiving the drug every two weeks. Forty percent of patients had complete resolution of at least one of the painful swollen joint nodules, known as tophi, a hallmark of severe gout. (more…)
