Intimate partner violence, health behaviours, and chronic physical illness among South African women

Objectives. An association between intimate partner violence and adverse physical health outcomes and health-risk behaviours among women has been established, most scientific research having been conducted in the USA and other developed countries. There have been few studies in developing countries, including South Africa, which has one of the highest rates of intimate partner violence in the world. We therefore sought to study the association between physical intimate partner violence and physical health outcomes and behaviours among South African women. Methods. Using data from the cross-sectional, nationally representative South African Stress and Health Study, we assessed exposure to intimate partner violence, health-risk behaviours, health-seeking behaviours and chronic physical illness among a sample of 1 229 married and cohabiting women. Results. The prevalence of reported violence was 31%. This correlated with several health-risk behaviours (smoking, alcohol consumption, and use of non-medical sedatives, analgesics and cannabis) and health-seeking behaviours (recent visits to a medical doctor or healer). Intimate partner violence was not significantly associated with chronic physical illness, although rates of headache, heart attack and high blood pressure reached near-significance. Conclusions. Partner violence against women is a significant public health problem in South Africa, associated with healthrisk behaviours and increased use of medical services. Public health programmes should incorporate interventions to mitigate the impact of violence on victims and reduce the risk of negative behavioural outcomes. Further investigation of the pathways between violence exposure and health behaviours is needed to inform the design of such programming

A facile method for the stain-free visualization of hierarchical structures with electron microscopy

Diblock copolymers form hierarchical morphologies with numerous applications in drug delivery and as nanoreactors. Yet, the visualization of these structures by electron microscopy can be extremely difficult, requiring complex staining techniques with associated health risks and the potential to alter structural morphology. Reported here is the synthesis of diblock copolymers by RAFT containing 3,5-bis(trifluoromethyl)phenyl functionality allowing for facile visualization of their resulting hierarchical structures by TEM with no further sample preparation.P.E.W. thanks the AWE and E.A. thanks Schlumberger for financial support, and J.d.B is grateful for a Marie Curie Intraeuropean Fellowship (project # 273807).

Experimental Tests of General Relativity

Einstein's general theory of relativity is the standard theory of gravity, especially where the needs of astronomy, astrophysics, cosmology and fundamental physics are concerned. As such, this theory is used for many practical purposes involving spacecraft navigation, geodesy, and time transfer. Here I review the foundations of general relativity, discuss recent progress in the tests of relativistic gravity in the solar system, and present motivations for the new generation of high-accuracy gravitational experiments. I discuss the advances in our understanding of fundamental physics that are anticipated in the near future and evaluate the discovery potential of the recently proposed gravitational experiments.Comment: revtex4, 30 pages, 10 figure

History of discovery of the patagonian lizards

Knowledge of the history is necessary to understand why things are today as they are. Argentinean and Chilean Patagonia have a very interesting story about the native fauna and its discovery. The main character of this story is an adventurer spirit wanting to increase knowledge by traveling to the “end of the world”, ignoring barriers only to search and see what is beyond. Many well-known naturalists have visited this land eager and willing to find new species never seen before, while others have made some amazing contributions while never setting one foot on Patagonian soil. In this chapter, we intend to summarize how Patagonian herpetofauna was discovered, described and studied over time. In addition, we want to mention important scientists, whose work led the way for the future researchers to come.Fil: Williams, Jorge Daniel.

MetaboLab - advanced NMR data processing and analysis for metabolomics

Background\ud Despite wide-spread use of Nuclear Magnetic Resonance (NMR) in metabolomics for the analysis of biological samples there is a lack of graphically driven, publicly available software to process large one and two-dimensional NMR data sets for statistical analysis.\ud \ud Results\ud Here we present MetaboLab, a MATLAB based software package that facilitates NMR data processing by providing automated algorithms for processing series of spectra in a reproducible fashion. A graphical user interface provides easy access to all steps of data processing via a script builder to generate MATLAB scripts, providing an option to alter code manually. The analysis of two-dimensional spectra (1H,13C-HSQC spectra) is facilitated by the use of a spectral library derived from publicly available databases which can be extended readily. The software allows to display specific metabolites in small regions of interest where signals can be picked. To facilitate the analysis of series of two-dimensional spectra, different spectra can be overlaid and assignments can be transferred between spectra. The software includes mechanisms to account for overlapping signals by highlighting neighboring and ambiguous assignments.\ud \ud Conclusions\ud The MetaboLab software is an integrated software package for NMR data processing and analysis, closely linked to the previously developed NMRLab software. It includes tools for batch processing and gives access to a wealth of algorithms available in the MATLAB framework. Algorithms within MetaboLab help to optimize the flow of metabolomics data preparation for statistical analysis. The combination of an intuitive graphical user interface along with advanced data processing algorithms facilitates the use of MetaboLab in a broader metabolomics context.\ud \u
