Diffusion markers of dendritic density and arborization in gray matter predict differences in intelligence
(Nature Research (part of Springer Nature), 2018)Previous research has demonstrated that individuals with higher intelligence are more likely to have larger gray matter volume in brain areas predominantly located in parieto-frontal regions. These findings were usually ... -
Knowledge, beliefs, and perceptions of tuberculosis among community members in Ntcheu district, Malawi
(Dove Medical Press, 2019)Introduction: The global burden of tuberculosis (TB) remains significantly high, with overreliance on biomedical interventions and inadequate exploration of the socioeconomic and cultural context of the infected population. ... -
High risk exposure to HIV among sexually active individuals who tested negative on rapid HIV Tests in the Tshwane District of South Africa - the importance of behavioural prevention measures
(Public Library of Science, 2018-02-02)Objective: To assess the prevalence of HIV risk behaviour among sexually active HIV sero-negative individuals in the Tshwane district of South Africa (SA). Methods: Demographic and HIV risk behaviour data were collected ... -
High human papillomavirus (HPV) prevalence in South African adolescents and young women encourages expanded HPV vaccination campaigns
(Public Library of Science, 2018-01-02)The objectives of the study were to investigate prevalence of cervical human papillomavirus (HPV) genotypes to inform HPV vaccination strategy in South Africa and to study factors associated with HPV prevalence. Sexually ... -
Population-level HIV incidence estimates using a combination of synthetic cohort and recency biomarker approaches in KwaZulu-Natal, South Africa
(Public Library of Science, 2018-09-13)Introduction: There is a notable absence of consensus on how to generate estimates of population-level incidence. Incidence is a considerably more sensitive indicator of epidemiological trends than prevalence, but is harder ... -
Two distance memories in desert ants - modes of interaction
(Public Library of Science, 2018-10-10)Navigation plays an essential role for many animals leading a mobile mode of life, and for central place foragers in particular. One important prerequisite for navigation is the ability to estimate distances covered during ... -
Computational analysis of antibody dynamics identifies recent HIV-1 infection
(American Society for Clinical Investigation, 2018)Accurate HIV-1 incidence estimation is critical to the success of HIV-1 prevention strategies. Current assays are limited by high false recent rates (FRRs) in certain populations and a short mean duration of recent infection ... -
Developing and implementing national health identifiers in resource limited countries : why, what, who, when and how?
(Taylor & Francis Open, 2018)Many resource-limited countries are scaling up health services and health-information systems (HISs). The HIV Cascade framework aims to link treatment services and programs to improve outcomes and impact. It has been adapted ... -
Complete genome sequence of dengue virus serotype 2, Asian/American genotype, isolated from the urine of a venezuelan child with hemorrhagic fever in 2016
(American Society for Microbiology, 2018)The complete genome sequence was obtained for a Dengue virus 2 isolate from the urine of an 8-year-old girl who was hospitalized with dengue hemorrhagic fever in 2016 in Venezuela. -
Competition between silicifiers and non-silicifiers in the past and present ocean and its evolutionary impacts
(Frontiers Media, 2018)Competition is a central part of the evolutionary process, and silicification is no exception: between biomineralized and non-biomineralized organisms, between siliceous and non-siliceous biomineralizing organisms, and ... -
Dynamics and control of infections on social networks of population types
(Elsevier, 2018)Random mixing in host populations has been a convenient simplifying assumption in the study of epidemics, but neglects important differences in contact rates within and between population groups. For HIV/AIDS, the ... -
The role of age-mixing patterns in HIV transmission dynamics : Novel hypotheses from a field study in Cape Town, South Africa
(Elsevier, 2018)Background: Age-disparate relationships are thought to put young women at increased risk of HIV, though current evidence is inconclusive. Studying population-level age-mixing patterns as well as individual-level measures ...
