In concentrated acid solutions these questions take on a further level of complexity, because the structure of the aqueous proton itself is uncertain, and may be influenced by the counterion. Here, we address these questions by studying the IR spectra of nitric acid as a function of concentration in H2O, and comparing these to the spectra of several alkali nitrate salts. Read More

Pharmacological interventions for acute hepatitis C infection.

Cochrane Database Syst Rev 2018 Dec 3;12:CD011644. Epub 2018 Dec 3.

Sheila Sherlock Liver Centre, Royal Free Hospital and the UCL Institute of Liver and Digestive Health, London, UK.

Background: Hepatitis C virus (HCV) is a single-stranded RNA (ribonucleic acid) virus that has the potential to cause inflammation of the liver. The traditional definition of acute HCV infection is the first six months following infection with the virus. Another commonly used definition of acute HCV infection is the absence of HCV antibody and subsequent seroconversion (presence of HCV antibody in a person who was previously negative for HCV antibody).

Omega-3 fatty acids for the primary and secondary prevention of cardiovascular disease.

Cochrane Database Syst Rev 2018 Nov 30;11:CD003177. Epub 2018 Nov 30.

Norwich Medical School, University of East Anglia, Norwich Research Park, Norwich, Norfolk, UK, NR4 7TJ.

Background: Researchers have suggested that omega-3 polyunsaturated fatty acids from oily fish (long-chain omega-3 (LCn3), including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)), as well as from plants (alpha-linolenic acid (ALA)) benefit cardiovascular health. Guidelines recommend increasing omega-3-rich foods, and sometimes supplementation, but recent trials have not confirmed this.

Objectives: To assess effects of increased intake of fish- and plant-based omega-3 for all-cause mortality, cardiovascular (CVD) events, adiposity and lipids. Read More

Extended cleavage specificities of mast cell proteases 1 and 2 from golden hamster: Classical chymase and an elastolytic protease comparable to rat and mouse MCP-5.

PLoS One 2018 6;13(12):e0207826. Epub 2018 Dec 6.

Department of Cell and Molecular Biology, Uppsala University, The Biomedical Center, Uppsala, Sweden.

Serine proteases constitute the major protein content of mast cell secretory granules. Here we present the extended cleavage specificity of two such proteases from the golden hamster, Mesocricetus auratus. Analysis by phage display technique showed that one of them (HAM1) is a classical chymase with a specificity similar to the human mast cell chymase. Read More

Secular trend in interobserver agreement of VIA diagnosis for cervical cancer screening in Nigeria.

PLoS One 2018 6;13(12):e0208531. Epub 2018 Dec 6.

Department of Strategic Information and Research, Institute of Human Virology Nigeria, Abuja, Nigeria.

Objective: In low resource settings, visual inspection with acetic acid (VIA) by allied health workers, has been suggested as an alternative for cervical cancer screening. However, there are concerns about the objectivity and time to diagnostic concordance with specialists. We evaluated the secular trend in interobserver agreement between nurse providers and a gynecologist/colposcopist over a five-year period. Read More

Association of pre-eclampsia risk with maternal levels of folate, homocysteine and vitamin B12 in Colombia: A case-control study.

PLoS One 2018 6;13(12):e0208137. Epub 2018 Dec 6.

Farr Institute of Health Informatics, University College London, London, United Kingdom.

Background: Maternal serum concentrations of folate, homocysteine, and vitamin B12 have been associated with pre-eclampsia. Nevertheless, reported studies involve limited number of cases to reliably assess the nature of these associations. Our aim was to examine the relation of these three biomarkers with pre-eclampsia risk in a large Colombian population. Read More
