HIV-related memory loss linked to Alzheimer’s protein

More than half of HIV patients experience memory problems and other cognitive impairments as they age, and doctors know little about the underlying causes. New research from the School of Medicine suggests HIV-related cognitive deficits share a common link with Alzheimer’s-related dementia: low levels of the protein amyloid beta in the spinal fluid.

Free, confidential HIV testing for World AIDS Day

Against expectations, genetic variation does not alter asthma treatment response

Studies have suggested that asthma patients with a specific genetic variation might not respond as well to certain treatments as those with a different variation. But a new study in this week’s edition of The Lancet shows that patients with either variation respond to combination treatment, and that this treatment should be continued, School of Medicine researchers report.

Amaizeing: Corn genome decoded

Iowa StateIn recent years, scientists have decoded the DNA of humans and a menagerie of creatures but none with genes as complex as a stalk of corn, the latest genome to be unraveled. A team of scientists led by The Genome Center at the School of Medicine published the completed corn genome in the Nov. 20 journal Science, an accomplishment that will speed efforts to develop better crop varieties to meet the world’s growing demands for food, livestock feed and fuel.

Surgery not linked to memory problems in older patients

For years, it has been widely assumed that older adults may experience memory loss and other cognitive problems following surgery. But a new study by School of Medicine researchers questions that assumption. In the 575 patients they studied, the investigators did not detect any long-term cognitive declines attributable to surgery.
