Fragmentation of intact proteins in the gas phase is influenced by amino acid composition, the mass and charge of precursor ions, higher order structure, and the dissociation technique used. The likelihood of fragmentation occurring between a pair of residues is referred to as the fragmentation propensity and is calculated by dividing the total number of assigned fragmentation events by the total number of possible fragmentation events for each residue pair. Here, we describe general fragmentation propensities when performing top-down mass spectrometry (TDMS) using denaturing or native electrospray ionization...

Depression has been reported to be associated with a greater risk of death and cardiovascular disease (CVD); however, the impact of antidepressants (ADM) on CVD risk remains controversial. Statin use is known to decrease CVD risk. Whether the use of these medications together affects CVD risk has not been studied. Patients (N = 26,828) completing the patient health questionnaire (PHQ-9), ≥40 years of age, without prior CVD, and no prior ADM use were studied. Depressive severity was categorized as none-mild (PHQ-9 score ≤14, n = 21,517) and moderate-severe (PHQ-9 score ≥15, n = 5311)...

BACKGROUND: As a category of bullying, mobbing is a form of violence in the workplace that damages the employing organization as well as the targeted employee. In Europe, the overall prevalence of mobbing in healthcare is estimated at 4%. However, few studies have explored mobbing among long-term care workers. OBJECTIVES: This study aims to examine the frequency of mobbing in Swiss nursing homes and its relationships with care workers' (i.e. registered nurse, licensed practical nurse, assistant nurse, nurse aide) health status, job satisfaction, and intention to leave, and to explore the work environment as a contributing factor to mobbing...

Cancer screening is a core component of family medicine but screening inequalities are well documented in Canada for foreign-born persons. Although people of Muslim faith and culture are the fastest growing immigrant population in Canada, there is little information in the literature about their cancer screening practices. Determining screening gaps could inform practice-based quality improvement initiatives. We conducted a retrospective chart review combining patient-level medical record data with self-reported religious affiliation to examine the relationship between religion and cancer screening in a large multi-site urban family practice...

UNLABELLED: The World Health Organization recommends that malaria be confirmed by parasitological diagnosis before treatment using Artemisinin-based Combination Therapy (ACT). Despite this, many health workers in malaria endemic countries continue to diagnose malaria based on symptoms alone. This study evaluates interventions to help bridge this gap between guidelines and provider practice. A stratified cluster-randomized trial in 42 communities in Enugu state compared 3 scenarios: Rapid Diagnostic Tests (RDTs) with basic instruction (control); RDTs with provider training (provider arm); and RDTs with provider training plus a school-based community intervention (provider-school arm)...

BACKGROUND: Younger adults are difficult to engage in preventive health, yet in Australia they are gaining more weight and increasing in waist circumference faster than middle-to-older adults. A further challenge to engaging 18- to 35-year-olds in interventions is the limited reporting of outcomes of recruitment strategies. OBJECTIVE: This paper describes the outcomes of strategies used to recruit young adults to a randomized controlled trial (RCT), healthy lifestyle mHealth program, TXT2BFiT, for prevention of weight gain...

BACKGROUND: Visceral leishmaniasis (VL) is a multifactorial disease, where the host genetics play a significant role in determining the disease outcome. The immunological role of anti-inflammatory cytokine, Interleukin 10 (IL10), has been well-documented in parasite infections and considered as a key regulatory cytokine for VL. Although VL patients in India display high level of IL10 in blood serum, no genetic study has been conducted to assess the VL susceptibility / resistance. Therefore, the aim of this study is to investigate the role of IL10 variations in Indian VL; and to estimate the distribution of disease associated allele in diverse Indian populations...

The title compound, C40H22Cl2O4, was formed by a Michael-Aldol domino reaction sequence, which coupled acenaphthene-quinone with 4-chloro-aceto-phenone in the presence of KOH in methanol. The dihedral angles between the central cyclo-penta-[a]ace-naphthyl-ene fused-ring system (r.m.s. deviation = 0.066 Å) and the 4-chloro-benzoyl rings are 62.25 (10) and 70.19 (10)°. The dihedral angle between the central ring system and the naphthoic acid grouping is 62.46 (7)°. This twisting of the pendant rings facilitates the formation of an intra-molecular aromatic π-π stacking inter-action between the 4-chloro-benzoyl and naphthoic acid rings, with centroid-centroid distances of 3...
