New findings may offer roadmap to predicting how the body will respond to a deadly habit
First- or second-hand exposure to cigarettes can lead to a variety of diseases, including tissue destruction found in pulmonary emphysema and osteoporosis. Also included among cigarette smoking-induced diseases are disorders in which an excessive deposition of fibrotic scar occurs, such as with atherosclerosis and idiopathic pulmonary fibrosis.
Collagen is the major protein of the white f
Brazils Pantanal, a vast wetland situated in the center of South America, has become the next frontier for leading-edge eco-tourists in search of ever more exotic flora and fauna. “Its where people go after theyve been to Africa,” says Shannon Bouton, a Ph.D. student in the School of Natural Resources and Environment (SNRE) at the University of Michigan.
This month, Bouton is publishing the results of her unique study of a wading bird colony in the Pantanal in the February
Differences in people seem to run in the blood, according to a recent study that examines which genes are active in blood cells. The work, published in this weeks online issue of the Proceedings of the National Academy of Sciences, found that the levels of several genes used by blood cells vary from person to person.
“Nobody had taken this broad a look at genetic variation in the blood of healthy people,” said David Relman, MD, associate professor of medicine at Stanford and a co-autho
Green fluorescence allows isolating the beta cells for study of their behavior and number in the pancreas
Diabetes mellitus (DM) affects at least 16 million Americans, ranks seventh as a cause of death in the United States, and costs the national economy over $100 billion yearly. About 95 percent of persons with DM have type 2.
Type 2 DM is characterized by insulin resistance in peripheral tissues as well as a defect in insulin secretion by beta cells. Insulin regulates ca
Study findings may offer prevention for avoiding those annoying spots caused by macular degeneration
The primary function of the retina is to capture light and initiate neural signals. The retina contains the photoreceptors, which are the site of sensory transduction in the visual pathway. Major landmarks in the retina are the fovea and macula, where light has a direct pathway to the receptors. An interruption of the blood supply to these landmarks can lead to age-related macular d
Ames Laboratory researcher’s microscale channels steer neurons to rewire damaged nerves
Using microscale channels cut in an ultrathin biodegradable polymer, a researcher at the U.S. Department of Energys Ames Laboratory is working to regrow nerve cells. The technique, which may one day allow the paralyzed to walk and the blind to see, has been proven to work for peripheral nerve regeneration in laboratory rats.
Nerve cells are unlike most other biological tissue. When a
