Four strains (km711T, km714, km542 and km524), representing a novel Legionella species, were isolated from aquatic environments in northern PR China. Cells were Gram-stain-negative, rod-shaped, microaerobic, motile and growth depended on l-cysteine. They grew at 25‒42 °C (optimum, 35‒37 °C) and could tolerate up to 1.5 % (w/v) NaCl (optimum, 0.5 %). The major fatty acids (>5 %) of the type strain km711T were C17  0 anteiso, C15  0 anteiso, iso-C16  0 and C16  1 ω7c and/or iso-C15  0 2OH. The pairwise comparison values were less then 96.1 % for 16S rRNA gene sequences, 23.3‒28.7 % interspecies variation for mip gene sequences, less then 93.6 % average nucleotide identity and less then 72.8 % average amino acid identity between these four strains and related type strains within the genus Legionella. The phylogenetic tree based on the four concatenated genes (16S rRNA, mip, rpoB and rnpB) and protein-concatamer tree based on concatenation of 21 protein markers both revealed that these four strains formed a separate phylogenetic branch cluster within the genus Legionella. The results of phenotypic and genotypic features suggest that these four strains represent a novel species of the genus Legionella, for which the name Legionella septentrionalis sp. nov. is proposed (type strain km711T=KCTC 15655T=NBRC 113219T).The Cre-Lox system is a highly versatile and powerful DNA recombinase mechanism, mainly used in genetic engineering to insert or remove desired DNA sequences. Valaciclovir It is widely utilized across multiple fields of biology, with applications ranging from plants, to mammals, to microbes. A key feature of this system is its ability to allow recombination between mutant lox sites. Two of the most commonly used mutant sites are named lox66 and lox71, which recombine to create a functionally inactive double mutant lox72 site. However, a large portion of the published literature has incorrectly annotated these mutant lox sites, which in turn can lead to difficulties in replication of methods, design of proper vectors and confusion over the proper nomenclature. Here, we demonstrate common errors in annotations, the impacts they can have on experimental viability, and a standardized naming convention. We also show an example of how this incorrect annotation can induce toxic effects in bacteria that lack optimal DNA repair systems, exemplified by Mycoplasma pneumoniae.Rabies is a lethal disease caused by Rabies lyssavirus, commonly known as rabies virus (RABV), and results in nearly 100 % death once clinical symptoms occur in human and animals. Long non-coding RNAs (lncRNAs) have been reported to be associated with viral infection. But the role of lncRNAs involved in RABV infection is still elusive. In this study, we performed global transcriptome analysis of both of lncRNA and mRNA expression profiles in wild-type (WT) and lab-attenuated RABV-infected mouse brains by using next-generation sequencing. The differentially expressed lncRNAs and mRNAs were analysed by using the edgeR package. We identified 1422 differentially expressed lncRNAs and 4475 differentially expressed mRNAs by comparing WT and lab-attenuated RABV-infected brains. Then we predicted the enriched biological pathways by the Gene Ontology (GO) and Kyoto Encyclopaedia of Genes and Genomes (KEGG) database based on the differentially expressed lncRNAs and mRNAs. Our analysis revealed the relationships between lncRNAs and RABV-infection-associated immune response and ion transport-related pathways, which provide a fresh insight into the potential role of lncRNA in immune evasion and neuron injury induced by WT RABV.Joint modeling analysis of longitudinal and time-to-event data has been an active area of statistical methodological study and biomedical research, but the majority of them are based on mean-regression. Quantile regression (QR) can characterize the entire conditional distribution of the outcome variable, and may be more robust to outliers/heavy tails and misspecification of error distribution. Additionally, a parametric specification may be insufficient and inflexible to capture the complicated longitudinal pattern of biomarkers. Thus, this study proposes novel QR-based partially linear mixed-effects joint models with three components (QR-based longitudinal response, longitudinal covariate, and time-to-event processes), and applies to Multicenter AIDS Cohort Study (MACS). Many common data features, including left-censoring due to a limit of detection, covariate measurement error, and asymmetric distribution, are considered to obtain reliable parameter estimates. Many interesting findings are discovered by the complicated joint models under Bayesian inference framework. Simulation studies are also implemented to assess the performance of the proposed joint models under different scenarios.

Effective interventions for overdose survivors are needed in the emergency departments (EDs). One promising model is the use of peer recovery coaches to engage with survivors in EDs, followed by partnering with community case management navigators to connect survivors to recovery support and treatment services. This paper describes the evaluation of a pilot program, the Recovery Opioid Overdose Team (ROOT), a warm hand-off system that links survivors to treatment services post-ED discharge.

The ROOT program is composed of a peer recovery coach who is in long-term recovery, and a case management navigator who specializes in mental health care and provides guidance for accessing community services. After an overdose reversal, law enforcement contacts a county 24/7 Crisis Team, who then notifies ROOT. The peer recovery coach engages with the survivor in the ED, and then follow up continues with the case management navigator and the peer recovery coach for up to 90 days post-ED discharge. Retrospective chartber 2017 through March 2019. Results Of the 122 referrals, 77.0% (n = 94) of the survivors initially engaged with ROOT in the ED or in the community. The remaining 23.0% (n = 28) left the ED against medical advice or were unengaged. The majority of overdose survivors were male (63.9%; n = 78), White (43.4%; n = 53), had housing (80.2%; n = 48), and access to transportation (48.4%; n = 59). From the 122 referrals, 33.6% (n = 41) received ongoing treatment services (n = 20 outpatient, n = 17 residential, n = 2 detoxification facility, n = 1 recovery housing, n = 1 medication treatment for opioid use disorder), 2.5% (n = 3) were incarcerated, 2.5% (n = 3) died, and 61.5% (n = 75) declined services. Conclusions The ROOT, a community-wide coordinated program in the EDs, shows promise in linking overdose survivors to recovery support and treatment services post-overdose.
