Depression linked to HIV risk among South African young people, study shows

2010-11-17
(Press-News.org) University of Alberta research has discovered a strong link between depression and risky sexual behaviours such as improper condom use, transactional sex and relationship violence among young people in South Africa.

The research shows that depression is common among young South Africans, and could be making a significant contribution towards the HIV epidemic.

As well, the researchers believe that depression could be contributing to risky sexual behaviours around the world, and that preventing or treating it may reduce the global burden of sexually transmitted diseases, including HIV and AIDS.

Ian Colman and Mzikazi Nduna, researchers from the U of A's School of Public Health, studied 1,002 females and 976 males between the ages of 15 and 26 living in Eastern Cape Province, South Africa. Study participants were surveyed twice, once in 2002, and again 12 months later.

The research found that 21.1 per cent of women and 13.6 per cent of men reported symptoms of depression. Depressed women were more likely to be in controlling relationships, to have a partner who was several years older, and to have experienced sexual violence. Men with depressed symptoms were more likely to have had three or more lifetime partners, experienced transactional sex and committed rape.

All of these behaviours are considered to put young women and men at risk for sexually transmitted HIV.

The research appears in the newest issue of the Journal of the International Aids Society.

Based on their findings, Colman and Nduna recommend routine screening for prevention, diagnosis and management of depression among youth as a means to reducing risky sexual behaviours and, in turn, HIV risk in South Africa.

"Access to mental-health services for young people remains elusive as resources and are directed to more pressing conditions such as teenage pregnancy and HIV prevention," Nduna said. The researchers see potential for blending depression prevention into current sexual and reproductive health clinic services. "Clearly we could achieve better success in our prevention efforts if they are delivered to clients who are in a healthy state of psychological well-being," added Colman, an assistant professor of epidemiology.

Listening for ocean spills and their ecological effects

2010-11-17
November 16, 2010 -- Scientists who study acoustics (the "science of sound") have over the years developed a variety of techniques to probe the hidden depths of oceans. This week, many of these acoustic researchers will come together to discuss how these technologies were used to monitor April's Deepwater Horizon oil spill, to present new data on the gusher's ecological impacts, and to highlight new techniques under development that could improve our ability to detect oil in ocean water. This special session will take place on November 17, 2010 at the 2nd Pan-American/Iberian ...

Research links damaged organs to change in biochemical wave patterns

2010-11-17
By examining the distinct wave patterns formed from complex biochemical reactions within the human body, diseased organs may be more effectively identified, says Zhengdong Cheng, associate professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, who has developed a model that simulates how these wave patterns are generated. His findings, which appear in the October issue of the journal "Physical Review E," detail Cheng's work with a system designed to model cells in a biochemical environment, similar to what occurs inside the human body. His ...

Study rewrites the evolutionary history of C4 grasses

Study rewrites the evolutionary history of C4 grasses
2010-11-17
CHAMPAIGN, Ill. — According to a popular hypothesis, grasses such as maize, sugar cane, millet and sorghum got their evolutionary start as a result of a steep drop in atmospheric carbon dioxide levels during the Oligocene epoch, more than 23 million years ago. A new study overturns that hypothesis, presenting the first geological evidence that the ancestors of these and other C4 grasses emerged millions of years earlier than previously established. The findings are published in the journal Geology. C4 plants are more efficient than C3 plants at taking up atmospheric ...

Program for young students increases interest in college attendance and medical careers

2010-11-17
Two new studies have shown that a unique program in East Harlem that helps middle school students learn practical health skills and gain a better understanding of medical conditions, such as diabetes and hypertension, resulted in increased interest in college attendance and medical careers among the students who attended the program. The results were presented at the American Public Health Association (APHA) Annual Meeting this month in Denver. The MedStart Summer Enrichment Program was created in the summer of 2009 by Edward Chu and Melissa Schneiderman, two third-year ...

Researchers link cerebral malaria to epilepsy, behavior disorders

Researchers link cerebral malaria to epilepsy, behavior disorders
2010-11-17
EAST LANSING, Mich. — Almost a third of cerebral malaria survivors developed epilepsy or other behavioral disorders in the most comprehensive study to date of the disease in African children, solidifying the link between malaria and neuropsychiatric disorders that affect hundreds of thousands of children. The research – led by Gretchen Birbeck, an associate professor of neurology and ophthalmology in Michigan State University's College of Osteopathic Medicine – appears in the current edition of The Lancet Neurology. Cerebral malaria is a severe form of malaria affecting ...

Nanotechnology: A dead end for plant cells?

2010-11-17
Using particles that are 1/100,000 the width of a human hair to deliver drugs to cells or assist plants in fighting off pests may sound like something out of a science fiction movie, but these scenarios may be a common occurrence in the near future. Carbon nanotubes, cylindrically shaped carbon molecules with a diameter of about 1 nanometer, have many potential applications in a variety of fields, such as biomedical engineering and medical chemistry. Proteins, nucleic acids, and drugs can be attached to these nanotubes and delivered to cells and organs. Carbon nanotubes ...

NERSC supercomputing center breaks the petaflops barrier

BERKELEY, Calif.—The Department of Energy's National Energy Research Scientific Computing Center (NERSC), already one of the world's leading centers for scientific productivity, is now home to the fifth most powerful supercomputer in the world and the second most powerful in the United States, according to the latest edition of the TOP500 list, the definitive ranking of the world's top computers. NERSC's newest supercomputer, a 153,408 processor-core Cray XE6 system, posted a performance of 1.05 petaflops (quadrillions of calculations per second) running the Linpack benchmark. ...

Infant estrogen levels tracked through diaper research

Infant estrogen levels tracked through diaper research
2010-11-17
With the help of babies and more than 5,000 of their diapers, Emory University researchers have developed an accurate, noninvasive method to determine estrogen levels in infants. The method, previously used in nonhuman primates, will allow researchers to learn more about the association between estrogen levels in human infants and their long-term reproductive development as well as the development of sex-specific behaviors, such as toy preference or cognitive differences. What's more, the method will also allow researchers to look at how early disruption of the endocrine ...

Enzyme action could be target for diabetes, heart disease treatments

2010-11-17
CINCINNATI—Cardiac researchers at the University of Cincinnati (UC) have found a new cellular pathway that could help in developing therapeutic treatments for obesity-related disorders, like diabetes and heart disease. This research is being presented at the American Heart Association's Scientific Session in Chicago Nov. 16. Tapan Chatterjee, PhD, and researchers in the division of cardiovascular diseases found that action by the enzyme histone deacetylase 9 (HDAC9) can lead to obesity-induced body fat dysfunction and that HDAC9-regulated pathways could be targets for ...
