Microbial diversities are key drivers of soil multifunctionality in terrestrial ecosystems and are important for stability and productivity of ecosystems. However, the relationships among microbial diversity, community assembly and soil multifunctionality in forest ecosystems remained unclear. Here, soil samples were collected from a subtropical forest ecosystem, Lushan Mountain, China. High-throughput sequencing was employed to reveal the bacterial/fungal community assembly and biodiversity, as well as 10 enzyme activities were measured to assess soil multifunctionality. We found that soil multifunctionality was negatively regulated by bacterial and fungal alpha diversity, implying a higher potential functional redundancy in this forest soil. The null model indicated that deterministic processes (variable selection) and stochastic processes (dispersal limitation) govern bacterial and fungal phylogenetic turnover, respectively. Correlation analysis revealed that bacterial rather than fungal community assembly processes have a significant linkage to soil multifunctionality. These observations projected that soil variables could regulate multifunctionality by shaping the phylogenetic and taxonomic turnover of bacteria rather than fungi. In summary, our study highlighted that soil multifunctionality is mainly driven by bacterial diversity and community assembly processes while not fungal, presenting different views and knowledge of microbial diversity and community assembly processes in ecosystem functioning.Lewis base catalysis provides powerful synthetic strategies for the selective construction of carbon-carbon and carbon-heteroatom bonds. Thus continuous efforts have been deployed to develop effective methodologies involving Lewis base catalysis. The nucleophilicity and steric hindrance of Lewis base catalyst often plays a major role in catalytic reactivity and selectivity in the reaction. In the past decades, tremendous progress has been made in the divergent construction of valuable motifs under Lewis base catalysis. In this review, we provide a comprehensive and updated summary of Lewis base-catalysed chemo-, diastereo- and enantiodivergent reaction, as well as the related mechanism will be highlighted in detail.

We evaluated the 2-year clinical outcomes of ST-elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) in patients with chronic kidney disease (CKD) who received newer-generation drug-eluting stents (DES).

Overall, 18,875 acute myocardial infarction patients were divided into two groups CKD (STEMI, n = 1707; NSTEMI, n = 1648) and non-CKD (STEMI, n = 8660; NSTEMI, n = 6860). The occurrence of major adverse cardiac events (MACE), defined as all-cause death, recurrent myocardial infarction (re-MI), any repeat coronary revascularization, and definite or probable stent thrombosis (ST), was evaluated.

After multivariable-adjusted analysis, in the CKD group, the MACE (adjusted hazard ratio [aHR] 1.365, p = 0.004), all-cause death (aHR 1.503, p = 0.004), noncardiac death (non-CD; aHR 1.960, p = 0.004), and all-cause death or MI rates (aHR 1.458, p = 0.002) were significantly higher in the NSTEMI group than in the STEMI group. In the non-CKD group, the non-CD rate (aHR 1.78, p = 0.006) was also higher in the NSTEMI group. The CD, re-MI, any repeat revascularization, and ST rates were similar between groups. In the CKD group, from 6 months to 2 years after the index procedure, all-cause death, non-CD, and all-cause death or MI rates were significantly higher in the NSTEMI group than in the STEMI group. These results may be related to the higher non-CD rate in the NSTEMI group.

In the era of contemporary newer-generation DES, NSTEMI showed a relatively higher non-CD rate than STEMI in both CKD and non-CKD groups.

Molecular diagnostics (MDx) increasingly gains importance in dermatology and its application is a prerequisite for personalized medicine. The goal of this cross-sectional study was to determine how MDx is implemented in dermatologists’ offices in the three fields of oncology, inflammation and infectiology and which hurdles office-based dermatologists face in terms of MDx.

Physician members of the Association of the German Dermatologists (Berufsverband der Deutschen Dermatologen e. V.; BVDD) were surveyed via an online questionnaire on MDx.

39.6% of the 192 participants reported using MDx. Of these, the vast majority used MDx for diagnosing infectious diseases (86.5% and 44.3% of users perform MDx for detection of funghi and sexually transmitted diseases, respectively). Only a small minority applied MDx to answer oncological or immunological questions. The major obstacles for non-users as compared to users were difficulties in implementation, lack of expertise as well as time, personnel, and technical availability. Reimbursement was a main issue in both groups.

Despite availability of specific therapies requiring precision medicine, MDx has not yet been broadly implemented in office-based dermatology. To advance MDx, more needs to be done in terms of continuous education, availability of reliable and valid tests, and reimbursability.

However, the abdominal muscles closely related to the movement flexibility mechanism have not been fully identified, limiting the potential biological advantage of their use in bionic mechanism design. In this study, we reveal the muscle distribution of the complete muscular driving unit in a honeybee abdomen using stereoscopy and scanning electron microscopy, and the muscle distribution was effectively verified using X-ray tomography. A novel equivalent unit mechanism (EUM) was then proposed and the kinematic analysis indicated that the extension ratio, bending angle, and swing angle of the EUM reached 9.36%, 1.22°, and 4.43°, respectively. The deformation ability of the EUM was consistent with the movement of the abdomen, confirming the movement flexibility. This work may provide a new perspective for distributed bionic mechanism design.Detection of bacterial burden within or near surgical wounds is critical to reducing the occurrence of surgical site infection (SSI). A distinct lack of reliable methods to identify postoperative bioburden has forced reliance on clinical signs and symptoms of infection (CSS). As a result, infection management has been reactive, rather than proactive. GW2580 in vivo Fluorescence imaging of bacterial burden (FL) is positioned to potentially flip that paradigm. This post hoc analysis evaluated 58 imaged and biopsied surgical site wounds from the multi-centre fluorescence imaging assessment and guidance clinical trial. Diagnostic accuracy measures of CSS and FL were evaluated. A reader study investigated the impact of advanced image interpretation experience on imaging sensitivity. Forty-four of fifty-eight surgical site wounds (75.8%) had bacterial loads >104 CFU/g (median = 3.11 × 105 CFU/g); however, only 3 of 44 were CSS positive (sensitivity of 6.8%). FL improved sensitivity of bacterial detection by 5.7-fold compared with CSS alone (P = .0005). Sensitivity improved by 11.3-fold over CSS among clinicians highly experienced with FL interpretation (P less then  .0001). Surgical sites that reach the stage of referral to a wound specialist frequently harbour asymptomatic high bacterial loads that delay healing and increase infection risk. Advanced imaging of pathological bacterial burden improves surgical site monitoring and may reduce the rate of SSIs.

Magnetic resonance imaging (MRI)-based investigations into radiotherapy (RT)-induced cardiotoxicity require reliable registrations of magnetic resonance (MR) imaging to planning computed tomography (CT) for correlation to regional dose. In this study, the accuracy of intra- and inter-modality deformable image registration (DIR) of longitudinal four-dimensional CT (4D-CT) and MR images were evaluated for heart, left ventricle (LV), and thoracic aorta (TA).

Non-cardiac-gated 4D-CT and T1 volumetric interpolated breath-hold examination (T1-VIBE) MRI datasets from five lung cancer patients were obtained at two breathing phases (inspiration/expiration) and two time points (before treatment and 5 weeks after initiating RT). Heart, LV, and TA were manually contoured. Each organ underwent three intramodal DIRs ((A) CT modality over time, (B) MR modality over time, and (C) MR contrast effect at the same time) and two intermodal DIRs ((D) CT/MR multimodality at same time and (E) CT/MR multimodality over time). Hausntrast is acceptably accurate per AAPM TG-132 guidelines. This study paves the way for future evaluation of RT-induced cardiotoxicity and its related factors using multimodality DIR.

Insect G protein-coupled receptors (GPCRs) have been identified as a new generation of attractive targets for RNA interference (RNAi)-based pest control. A functional study of the leucine-rich repeat-containing (LGR2) gene in Hyphantria cunea (HLGR2) was performed to examine whether it can be used in the molecular control of this notorious pest.

The complementary DNA (cDNA) sequence and deduced amino acids of HLGR2 were obtained and analyzed in the present study. HLGR2 is a typical GPCR and shows high structural and sequence similarity with other insect LGR2 proteins. The spatiotemporal expression profiles of HLGR2 showed that HLGR2 was highly expressed at the egg stage and tissues of head and silk gland. After RNAi of HLGR2, distinct phenotypes were observed when HLGR2 expression was suppressed, indicating that HLGR2 is essential in pupation and eclosion. HLGR2 RNAi led to a low pupation rate (45.00%), body malformation, abnormal wing expansion, failed cuticle melanization (63.33%), and high mortality rate (48.
