People suffering from asthma or other chronic lung problems are typically only able to get a measure of their lung function at the doctor’s office a few times a year by blowing into a specialized piece of equipment. More frequent testing at home could detect problems earlier, potentially avoiding emergency room visits and hospitalization. (more…)
Doctors can improve treatment programs using this knowledge
COLUMBIA, Mo. – The human immunodeficiency virus (HIV) can contain dozens of different mutations, called polymorphisms. In a recent study an international team of researchers, including University of Missouri scientists, found that one of those mutations, called 172K, made certain forms of the virus more susceptible to treatment. Soon, doctors will be able to use this knowledge to improve the drug regimen they prescribe to HIV-infected individuals.
“The 172K polymorphism makes certain forms of HIV less resistant to drugs,” said Stefan Sarafianos, corresponding author of the study and a researcher at MU’s Bond Life Sciences Center. “172K doesn’t affect the virus’ normal activities. In some varieties of HIV that have developed resistance to drugs, when the 172K mutation is present, resistance to two classes of anti-HIV drugs is suppressed. We estimate up to 3 percent of HIV strains carry the 172K polymorphism.” (more…)
Using new lensless imaging platform, team observes rare helical movements
A team of researchers from the UCLA Henry Samueli School of Engineering and Applied Science has, for the first time, directly recorded the three-dimensional helical swimming patterns of human sperm cells. (more…)
Scientists used genetic sequencing to discover that the vaccine used in the RV144 HIV vaccine trial, involving 16,000 men and women in Thailand, did offer some protection against certain HIV viruses. The results were published Sept. 10 in the online edition of Nature. (more…)
Berkeley Lab Researchers Identify Possible New Oncogene and Future Therapy Target
A gene that may possibly belong to an entire new family of oncogenes has been linked by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) with breast cancer resistance to a well-regarded and widely used cancer therapy. (more…)
EAST LANSING, Mich. — Reading a classic novel such as “Pride and Prejudice” can be entertaining, but, according to new research by a Michigan State University professor, it also can provide many other benefits beyond that.
Natalie Phillips, an MSU assistant professor of English, and her team placed study participants in an MRI machine and monitored their brain flow while reading the works of Jane Austen. (more…)
COLLEGE PARK, Md. – Moderate exercise may help people cope with anxiety and stress for an extended period of time post-workout, according to a study by kinesiology researchers in the University of Maryland School of Public Health published in the journal Medicine and Science in Sports and Exercise.
“While it is well-known that exercise improves mood, among other benefits, not as much is known about the potency of exercise’s impact on emotional state and whether these positive effects endure when we’re faced with everyday stressors once we leave the gym,” explains J. Carson Smith, assistant professor in the Department of Kinesiology. “We found that exercise helps to buffer the effects of emotional exposure. If you exercise, you’ll not only reduce your anxiety, but you’ll be better able to maintain that reduced anxiety when confronted with emotional events.” (more…)
Hospitals that continue CPR longer have better survival rates from cardiac arrests, according to a study published online Sept. 5 in The Lancet. The findings challenge the assumption that, if a pulse is not restored soon, continuing resuscitation efforts is futile.
The results also showed that patients who recovered after an extended CPR effort were no more likely to suffer brain damage than are patients revived after a shorter effort. (more…)
