EAST LANSING, Mich. — Researchers at Michigan State University are working to show how a noninvasive, drug-free form of hands-on medical care can help patients with chronic obstructive pulmonary disease improve their breathing.
The team from MSU’s College of Osteopathic Medicine will apply four osteopathic manipulative treatments to a group of patients with moderate to severe chronic obstructive pulmonary disease. One of the most common lung diseases, COPD typically manifests as chronic bronchitis (a long-term cough with mucus) or emphysema (destruction of the lungs over time). (more…)
As medical researchers and engineers try to shrink diagnostics to fit in a person’s pocket, one question is how to easily move and mix small samples of liquid.
University of Washington researchers have built and patented a surface that, when shaken, moves drops along certain paths to conduct medical or environmental tests.
“This allows us to move drops as far as we want, and in any kind of layout that we want,” said Karl Böhringer, a UW professor of electrical engineering and bioengineering. The low-cost system, published in a recent issue of the journal Advanced Materials, would require very little energy and avoids possible contamination by diluting or electrifying the samples in order to move them.

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…)

What if you could remove lead from a person’s blood with a bacterial protein that snags the toxic metal?
Or treat spinal cord injury by shutting off a gene that prevents nerve regrowth?
Ideas like these used to be the exclusive province of practicing biologists. But they are among 14 ideas conceived and presented recently by students in the University of Minnesota’s introductory biology course.(more…)
*Engineers at Brown University have designed a biological device that can measure glucose concentrations in human saliva. The technique could eliminate the need for diabetics to draw blood to check their glucose levels. The biochip uses plasmonic interferometers and could be used to measure a range of biological and environmental substances. Results are published in Nano Letters.*
PROVIDENCE, R.I. [Brown University] — For the 26 million Americans with diabetes, drawing blood is the most prevalent way to check glucose levels. It is invasive and at least minimally painful. Researchers at Brown University are working on a new sensor that can check blood sugar levels by measuring glucose concentrations in saliva instead.
The technique takes advantage of a convergence of nanotechnology and surface plasmonics, which explores the interaction of electrons and photons (light). The engineers at Brown etched thousands of plasmonic interferometers onto a fingernail-size biochip and measured the concentration of glucose molecules in water on the chip. Their results showed that the specially designed biochip could detect glucose levels similar to the levels found in human saliva. Glucose in human saliva is typically about 100 times less concentrated than in the blood. (more…)
Energy drinks are a recent invention of mankind, even though their ingredients have long been used to stimulate the nervous system. They have become the salvation for students during the exams and office workers that have to meet the deadlines. Yet, are these products as good as they seem? (more…)
ANN ARBOR, Mich.— As Halloween approaches, tales of monsters and creepy crawlies abound. Among the most fearsome is the legendary beast known as the chupacabras.
But the real fiend is not the hairless, fanged animal purported to attack and drink the blood of livestock; it’s a tiny, eight-legged creature that turns a healthy, wild animal into a chupacabras, says University of Michigan biologist Barry OConnor. (more…)
