Fractal analysis methods are used to quantify the complexity of the human cerebral cortex. Many recent studies have focused on high resolution three-dimensional reconstructions of either the outer (pial) surface of the brain or the junction between the gray and white matter, but ignore the structure between these surfaces. This study uses a new method to(More)
Using an iterative design process, we designed and evaluated a system for college students to encourage the development and maintenance of healthy diet and exercise habits. The system has three components: a camera phone application to support photographic diet and exercise journaling, an automatic workout tracking application for exercise machines in the(More)
BACKGROUND HIV/AIDS and Ebola Virus Disease (EVD) are contemporary epidemics associated with significant social stigma in which communities affected suffer from social rejection, violence, and diminished quality of life. OBJECTIVE To compare and contrast stigma related to HIV/AIDS and EVD, and strategically think how lessons learned from HIV stigma can be(More)
Human Papillomavirus (HPV) infection is the most common sexually transmitted infection (STI) worldwide. Incidence rates of HPV infection among human immunodeficiency virus (HIV)-infected individuals are well documented and are several-fold higher than among HIV-uninfected individuals. Few studies have demonstrated an increased risk for acquiring HIV(More)
Inherited deficiency in the mitochondrial protein frataxin (FXN) causes the rare disease Friedreich's ataxia (FA), for which there is no successful treatment. We identified a redox deficiency in FA cells and used this to model the disease. We screened a 1600-compound library to identify existing drugs, which could be of therapeutic benefit. We identified(More)
INTRODUCTION Approximately 291 million women worldwide are HPV DNA carriers. Studies have indicated that having multiple sexual partners may lead to higher HPV transmission. Thus female sex workers (FSWs) may be at greater risk of infection compared to the general population. Herein we review publications with data on FSW cervical HPV test results. We also(More)
BACKGROUND Sexual behaviour and sexual practices affect the risk for acquisition and transmission of HIV infection. This study tries to identify differences in sexual behaviour (condom use with non-marital partners, multiple sexual partnerships transactional sex and age mixing in sexual relationships), sexual practices (oral, anal and vagina sex), and(More)
A dolescents worldwide often face tremendous sexual violence; a growing problem and a leading reproductive health concern. The prevalence of this violence ranges between 15 and 40% in sub-Saharan Africa, with studies showing rates of sexual coercion and abuse among female adolescents in Nigeria between 11 and 55% (1, 2). Little is known about the impact of(More)
itting at his laboratory bench, a scientist adds mutation after mutation to a strand of rabies virus RNA, unaware that in a few short days, an outbreak of this very mutation would destroy society as we know it. It could be called " Zombie Rabies, " a moniker befitting of the next Hollywood blockbuster—or, in this case, a representation of the debate over(More)
Two hundred female sex workers (FSWs) in Lima, Peru were randomized to receive HPV4 vaccine in the standard (0, 2, 6 months) or a modified schedule (0, 3, 6 months). One hundred and eighty four (92%) participants completed 3 doses of vaccine. Baseline seropositive rates were 58% for HPV6, 22.5% for HPV11, 41.5% for HPV16, and 13% for HPV18. The final(More)
