Total joint arthroplasty (TJA) is an effective treatment for end-stage osteoarthritis, which aims to alleviate pain and improve function and mobility. Despite the remarkable success of TJA, complications can arise, leading to unplanned hospital readmission, implant failure, morbidity and mortality. Recently, there has been a growing interest in analysing sex-based differences in diseases and response to medical interventions. This review summaries evidence pertaining to the widening gap between men and women regarding the utilization and outcome of TJA surgery. Interactions between sex and patient-reported outcome, implant failure and medical complication are complex and often demonstrate conflicting results. Significantly, there is a global consensus that men are at a higher risk of developing prosthetic joint infection following joint arthroplasty. Guided by the literature, there is a clear need for standardized methods of collecting, analysing and reporting sex-specific data to improve outcomes for both men and women who undergo TJA.Genetic signal detection in genome-wide association studies (GWAS) is enhanced by pooling small signals from multiple Single Nucleotide Polymorphism (SNP), for example, across genes and pathways. Because genes are believed to influence traits via gene expression, it is of interest to combine information from expression Quantitative Trait Loci (eQTLs) in a gene or genes in the same pathway. Such methods, widely referred to as transcriptomic wide association studies (TWAS), already exist for gene analysis. Due to the possibility of eliminating most of the confounding effects of linkage disequilibrium (LD) from TWAS gene statistics, pathway TWAS methods would be very useful in uncovering the true molecular basis of psychiatric disorders. However, such methods are not yet available for arbitrarily large pathways/gene sets. This is possibly due to the quadratic (as a function of the number of SNPs) computational burden for computing LD across large chromosomal regions. To overcome this obstacle, we propose JEPEGMIX2-P, a novel TWAS pathway method that (a) has a linear computational burden, (b) uses a large and diverse reference panel (33 K subjects), (c) is competitive (adjusts for background enrichment in gene TWAS statistics), and (d) is applicable as-is to ethnically mixed-cohorts. To underline its potential for increasing the power to uncover genetic signals over the commonly used nontranscriptomics methods, for example, MAGMA, we applied JEPEGMIX2-P to summary statistics of most large meta-analyses from Psychiatric Genetics Consortium (PGC). While our work is just the very first step toward clinical translation of psychiatric disorders, PGC anorexia results suggest a possible avenue for treatment.Limb reduction defects (LRDs) that affect multiple limbs are considered to be more often heritable, but only few studies have substantiated this. We aimed to investigate if an etiological diagnosis (genetic disorder or clinically recognizable disorder) is more likely to be made when multiple limbs are affected compared to when only one limb is affected. We used data from EUROCAT Northern Netherlands and included 391 fetuses and children with LRDs born in 1981-2017. Cases were classified as having a transverse, longitudinal (preaxial/postaxial/central/mixed), intercalary, or complex LRD of one or more limbs and as having an isolated LRD or multiple congenital anomalies (MCA). We calculated the probability of obtaining an etiological diagnosis in cases with multiple affected limbs versus one affected limb using relative risk (RR) scores and Fisher's exact test. We showed that an etiological diagnosis was made three times more often when an LRD occurred in multiple limbs compared to when it occurred in one limb (RR 2.9, 95% CI 2.2-3.8, p  less then  0.001). No genetic disorders were found in isolated cases with only one affected limb, whereas a genetic disorder was identified in 16% of MCA cases with one affected limb. A clinically recognizable disorder was found in 47% of MCA cases with one affected limb. Genetic counseling rates were similar. We conclude that reduction defects of multiple limbs are indeed more often heritable. Genetic testing seems less useful in isolated cases with one affected limb, but is warranted in MCA cases with one affected limb.γ-Zirconium phosphate (γ-ZrP) has potential as a very useful inorganic ion-exchanger due to its stability under thermal and acidic conditions. We recently reported its facile synthesis using a modified solventless method, which could make the exploitation of its ion-exchange properties for cleanup of radioactive materials and extraction of valuable ions feasible. The adsorption isotherms of Rb+ and Sr2+ over γ-ZrP are described well with the Langmuir model, with maximum adsorption capacity of 1.52 and 1.31 mmol/g, respectively. Both ions adsorb on γ-ZrP following pseudo-second order kinetics with a much faster uptake of Rb+ than of Sr2+ . γ-Zirconium phosphate shows very high affinity for Rb+ , allowing its enrichment from low-concentration solutions. Notably, Rb+ is selectively removed from complex solutions containing large amounts of Na+ , Mg2+ , Ca2+ , or transition metals such as Cu2+ , Ni2+ , Fe2+ , Fe3+ , Co2+ and Zn2+ . The used sorbent can be fully regenerated by nitric acid, enabling the recovery of Rb+ .

Pine wilt disease (PWD) is a plant disease that causes serious damage to pine trees. PWD occurs when the host plant is infected with pinewood nematode (PWN), Bursaphelenchus xylophilus. In this study, a compound with nematicidal activity was isolated from actinomycetes and its efficacy was investigated in vitro.

We screened and selected Streptomyces sp. 680560, which had nematicidal activity against B. xylophilus. Based on 16S rRNA sequence analysis, it showed 99.93% similarity with Streptomyces blastmyceticus NRRB-5480

. Furthermore, the active compound was isolated and identified as teleocidin B4. Teleocidin B4 at concentrations ranging from 6.25 to 100 μM had low nematicidal activity after 24 and 36 h against adult and stage juveniles (J2) of B. xylophilus, but after 48 h nematicidal activity exceeded 95%. The rate of inhibition of egg hatching for Teleocidin B4 6.25, 12.5, 25, 50, and 100 μM was confirmed to be dose-dependently inhibited after 48 h of treatment. Teleocidin B4 is not only toxic to ha as a PWD control agent. © 2020 Society of Chemical Industry.

Physical and emotional conditions of patients treated in an intensive care unit (ICU) may be adversely affected by environmental stressors.

The aim of this study was to investigate the relationship between patients' anxiety and depression levels and environmental stressors in the ICU.

This was a descriptive cross-sectional study.

The study was conducted between June 2018 and April 2019 with 150 patients treated in the ICUs of a training and research hospital. Patient information form and ICU environmental stressors and hospital anxiety and depression scales were used for data collection. Descriptive statistics, t-test, one-way analysis of variance, and Pearson's correlation coefficient were used to evaluate the data.

The mean hospital anxiety score of the patients in ICUs was 11.1 ± 2.7, and 77.3% of patients were at risk for anxiety (10-point cut-off). The mean hospital depression score was 10.6 ± 3.3, and 94% of patients were at risk for depression (7-point cut-off). The mean score of environmental stressors was 123.9 ± 13.1. A moderate positive correlation between hospital anxiety and hospital depression (r = .63, P < .001) and a weak negative correlation between environmental stressors and hospital anxiety (r = -.24, P = .003) were found. However, no significant correlation between environmental stressors and hospital depression was found (r = -.13, P = .12).

According to this study, the environmental stressors in the ICU were high, and the patients were at risk of anxiety and depression. The depression levels of the patients increased along with their anxiety levels. Selleck Encorafenib As environmental stressors increased, hospital anxiety levels of the patients decreased. However, there was no significant relationship between environmental stressors and patients' hospital depression levels.

Environmental stressors in ICUs are high, and the patients in the ICUs are at risk of anxiety and depression.

Environmental stressors in ICUs are high, and the patients in the ICUs are at risk of anxiety and depression.Polylactide and polycaprolactone are both biodegradable polymers produced through metal-catalyzed ring-opening polymerization. For a truly sustainable lifecycle of these polymers it is essential to replace the industrially used cytotoxic catalyst tin(II) bis(2-ethylhexanoate) [Sn(Oct)2 ] with non-toxic alternatives. Here, we report the fastest known robust catalyst in the polymerization of lactide and ϵ-caprolactone. This zinc guanidine catalyst can polymerize non-purified technical rac-lactide and ϵ-caprolactone in the melt at different [M]/[I] ratios with fast rate constants, high molar masses, and high yields in a short time, leading to colorless, transparent polymer. Moreover, we report that polylactide and polycaprolactone produced by zinc-guanidine complexes have favorably high crystallinities. In fact, the obtained polylactide shows a more robust degradation profile than its Sn(Oct)2 -catalysed equivalent due to a higher degree of crystallinity.Homogeneous gold (Au) complexes have demonstrated tremendous utility in modern organic chemistry; however, their application for the synthesis of polymers remains rare. Herein, we demonstrate the first catalytic application of Au complexes toward the polycondensation of alkyne-containing comonomers and heteroarene nucleophiles. Polymerization occurs through successive intermolecular hydroarylation reactions to produce high molecular weight aromatic copolymers with 1,1-disubstituted alkene backbone linkages. Clear correlations between the rate and degree of polymerization (DP) were established based on catalyst structure and counterion pairing, thus enabling polymerization reactions that proceeded with remarkable efficiency, high reactivity, and exceptional DPs. The reactivity is broad in scope, enabling the copolymerization of highly functionalized aromatic and aliphatic monomers. These results highlight the untapped utility of Au catalysis in providing access to new macromolecular constructs.The AcOEt extract of Artemisia argyi-derived fungus Trichoderma koningiopsis QA-3 showed potent inhibitory activity against pathogenic bacteria. Fractionation of the extract resulted in the isolation of three new polyketides (1-3) and two new terpenoids (4 and 5), together with three known metabolites (6-8). Their chemical structures were analyzed by NMR spectra, ECD, HR-ESI-MS or HR-EI-MS, optical rotation, and X-ray crystallographic data, as well as by comparison with literature reports. In the antibacterial assays, 3-hydroxyharziandione (4) showed potent activity against human pathogen Escherichia coli with an MIC value of 0.5 μg/mL, while 6-(3-hydroxypent-1-en-1-yl)-2H-pyran-2-one exhibited strong activity against marine-derived aquatic pathogen Micrococcus luteus with an MIC value of 1.0 μg/mL.
