Your DNA-dependent Protease AtWSS1A depresses prolonged double strand split formation in the course of reproduction.
Recent, rapid radiations present a challenge for phylogenetic reconstruction. Fast successive speciation events typically lead to low sequence divergence and poorly resolved relationships with standard phylogenetic markers. Target sequence capture of many independent nuclear loci has the potential to improve phylogenetic resolution for rapid radiations.

Here we applied target sequence capture with 353 protein-coding genes (Angiosperms353 bait kit) to Veronica sect. Hebe (common name hebe) to determine its utility for improving the phylogenetic resolution of rapid radiations. Veronica section Hebe originated 5-10 million years ago in New Zealand, forming a monophyletic radiation of ca 130 extant species.

We obtained approximately 150 kbp of 353 protein-coding exons and an additional 200 kbp of flanking noncoding sequences for each of 77 hebe and two outgroup species. When comparing coding, noncoding, and combined data sets, we found that the latter provided the best overall phylogenetic resolution. Whileer study of rapid radiations.
To explore racial disparities in self-reports of violent victimization and polyvictimization among young girls in Brazil and to analyze the distribution of prevalence rates across race groups and the estimated odds of exposure.

Data from girls ages 15 and above (N=14,809) from the 2015 edition of PeNSE (National Adolescent School-based Health Survey) were analyzed. Survey weighted proportions and bivariate and multivariate logistic regressions were used to address the objectives.

Independent of the girls' age, socioeconomic status, and region of residence, black, indigenous, mixed, and Asian descendant girls (relative to Whites) were more likely to report past experiences of being bullied, suffering physical violence, forced sexual intercourse, and polyvictimization (reporting all three events). Blacks had the highest rates of reporting being bullied and polyvictimization. Asian descendants had the highest reports of physical violence. Indigenous girls had the highest reports of forced sexual intercourse.

This study documented disproportionate risks of violent victimization for young women of color among Brazilian students. The risks were significantly greater for those of darker skin tones and from ethnic minorities.

These findings can inform the development of programs to protect young women from violence in Brazil and highlight the importance of including anti-racism strategies in such programs.

The opportunistic multi-drug resistant nosocomial gram negative bacilli Serratia marcescens (S. marcescens) is a rising contributor to spinal implant infections (Iguchi et al., Genome Biol Evol 62096-2110, 2014; Teresa et al., J Clin Microbiol 552334-2347; Dante et al., J Clin Microbiol 54120-126). Selleckchem Etomoxir This study investigates the most effective matrix ratio of an antibiotic-independent, silver carboxylate-doped titanium dioxide (TiO
)-polydimethylsiloxane (PDMS) coating in preventing adherence of multidrug resistant pathogen S. marcescens to spinal implant materials.

This project examined an antibiotic-independent, silver carboxylate-doped titanium dioxide (TiO
)-polydimethylsiloxane (PDMS) coating on three common spinal implant materials, polyetheretherketone (PEEK), stainless steel (SS), and titanium (Ti), which previously were found to be prone to bacterial adhesion (Garcia et al., Spine Deform 8351-359). After generation of dose response curves to find the optimal silver carboxylate concentration, 95% Tte most effectively decreases adherence of S. marcescens on spinal implants. These results suggest that the application of a non-antibiotic, bactericidal coating prior to spinal surgery may prevent the adherence and proliferation of MDR S. marcescens and decrease the incidence of spinal SSI.DNA double-strand breaks (DSBs) represent the most cytotoxic DNA lesions, as-if mis- or unrepaired-they can cause cell death or lead to genome instability, which in turn can cause cancer. DSBs are repaired by two major pathways termed homologous recombination and non-homologous end-joining (NHEJ). NHEJ is responsible for repairing the vast majority of DSBs arising in human cells. Defects in NHEJ factors are also associated with microcephaly, primordial dwarfism and immune deficiencies. One of the key proteins important for mediating NHEJ is XRCC4. XRCC4 is a dimer, with the dimer interface mediated by an extended coiled-coil. The N-terminal head domain forms a mixed alpha-beta globular structure. Numerous factors interact with the C-terminus of the coiled-coil domain, which is also associated with significant self-association between XRCC4 dimers. A range of construct lengths of human XRCC4 were expressed and purified, and the 1-164 variant had the best NMR properties, as judged by consistent linewidths, and chemical shift dispersion. In this work we report the 1H, 15 N and 13C backbone resonance assignments of human XRCC4 in the solution form of the 1-164 construct. Assignments were obtained by heteronuclear multidimensional NMR spectroscopy. In total, 156 of 161 assignable residues of XRCC4 were assigned to resonances in the TROSY spectrum, with an additional 11 resonances assigned to His-Tag residues. Prediction of solution secondary structure from a chemical shift analysis using the TALOS + webserver is in good agreement with the published X-ray crystal structures of this protein.
Golimumab (GLM) has been reported to have lower immunogenicity than do other TNF inhibitors used for treating rheumatoid arthritis (RA). We previously found a prolonged effect of and improvement similar to that associated with infliximab (IFX) after switching to subcutaneous GLM (GLM-SC) for control of RA activity or adverse events. Thus, this study aimed to evaluate the continued maintenance of treatment efficacy and safety for > 2 years by switching to GLM-SC in RA patients with low disease activity or in remission after previous treatment with another tumor necrosis factor (TNF) inhibitor.

Thirty-two patients treated with etanercept or infliximab were switched to GLM-SC and maintained low disease activity. The patients were divided into two groups (GLMq4w and GLMq8w) through discussion with each patient, considering their general condition and convenience. The groups included patients with low disease activity or in remission who switched to 50-mg GLM therapy at 4-week and 8-week intervals, respectively.
