Cervical cancer (CC) is the second most common cancer in Western Africa, accounting for 12,000 cases and 6000 deaths annually. While vaccination against human papilloma virus (HPV) and CC screenings reduce the incidence and mortality of CC in many developed countries, 90% of CC deaths are in low-income countries. Lack of knowledge about the connection between HPV and CC, lack of access to vaccines and screenings, weak healthcare infrastructure, and stigma related to sexually transmitted diseases are among the factors that contribute to this disparity.

Exploring the interactions between the Ca binding protein calmodulin (CaM) and its target proteins remains a challenging task. Members of the Munc13 protein family play an essential role in short-term synaptic plasticity, modulated via the interaction with CaM at the presynaptic compartment. In this study, we focus on the bMunc13-2 isoform expressed in the brain, as strong changes in synaptic transmission were observed upon its mutagenesis or deletion.

This communication assesses the use of a portable near infrared (NIR) instrument to measure quantitative (fatty acid profile) properties and qualitative ('Premium' and 'Non-premium') categories of individual Iberian pork carcasses at the slaughterhouse. Acorn-fed Iberian pigs have more unsaturated fats than pigs fed conventional compound feed. Recent advances in miniaturisation have led to a number of handheld NIR devices being developed, allowing processing decisions to be made earlier, significantly reducing time and costs.

A history of childhood abuse has been linked to serious and long-lasting problems in adulthood. We developed two theoretical models concerning how early adverse experiences affect health in adulthood, and we tested the empirical fit of the two models in a population-based representative sample of Canadian adults (N = 25,113) using a structural equation modelling (SEM) technique, path analysis. The first model included direct pathways by which a history of three types of childhood abuse-exposure to intimate partner violence, physical abuse, and sexual abuse-affected adult physical and mental health, as well as indirect pathways by which perceived social support and everyday life stress acted as mediators of these associations.

The number of publications in the field of chemical cross-linking combined with mass spectrometry (XL-MS) to derive constraints for protein three-dimensional structure modeling and to probe protein-protein interactions has increased during the last years. As the technique is now becoming routine for in vitro and in vivo applications in proteomics and structural biology there is a pressing need to define protocols as well as data analysis and reporting formats. Such consensus formats should become accepted in the field and be shown to lead to reproducible results.

During the last two decades, cross-linking combined with mass spectrometry (MS) has evolved as a valuable tool to gain structural insights into proteins and protein assemblies. Structural information is obtained by introducing covalent connections between amino acids that are in spatial proximity in proteins and protein complexes. The distance constraints imposed by the cross-linking reagent provide information on the three-dimensional arrangement of the covalently connected amino acid residues and serve as basis for de-novo or homology modeling approaches.

Chemical cross-linking in combination with mass spectrometric analysis of the created cross-linked products is an emerging technology aimed at deriving valuable structural information from proteins and protein complexes. The goal of our protocol is to obtain distance constraints for structure determination of proteins and to investigate protein-protein interactions. We present an integrated workflow for cross-linking/mass spectrometry (MS) based on protein cross-linking with MS-cleavable reagents, followed by enzymatic digestion, enrichment of cross-linked peptides by strong cation-exchange chromatography (SCX), and LC/MS/MS analysis.

Research from the United States and Canada suggest that interracial relationships tend to have an elevated prevalence of intimate partner violence (IPV). Among seven extant studies, only one empirically examined speculations in the literature for this relationship. Based on analyses of data from Statistics Canada's 2009 General Social Survey (GSS), Brownridge was not able to fully account for the elevated odds of IPV in interracial relationships.

Cleavable cross-linkers are gaining increasing importance for chemical cross-linking/mass spectrometry (MS) as they permit a reliable and automated data analysis in structural studies of proteins and protein assemblies. Here, we introduce 1,3-diallylurea (DAU) as the first CID-MS/MS-cleavable, photo-thiol-reactive cross-linker. DAU is a commercially available, inexpensive reagent that efficiently undergoes an anti-Markovnikov hydrothiolation with cysteine residues in the presence of a radical initiator upon UV-A irradiation.

A major challenge in cross-linking/mass spectrometry (MS) is targeting carboxyl functions in proteins under physiological conditions that do not disturb the protein's conformation. Cross-linking of glutamic acid and aspartic acid residues in proteins will greatly expand the scope of structural mass spectrometry. We discovered that carboxyl-reactive cross-linkers have already been employed for many years in cross-linking/MS studies, yet in a completely different context.
