A technique for simultaneous measurement of a 2D bend by using a cantilever-mounted fibre Bragg grating (FBG) is experimentally demonstrated. The value of the two-dimensional deflections is acquired from the central wavelength and chirp bandwidth of the reflection spectrum via the inverse sensitivity matrix. Moreover, an interrogation system with an intensity modulator and a Mach–Zehnder interferometer structure is demonstrated, not only providing wavelength information, but also distinguishing the direction of the horizontal deflection. The measured vertical deflection sensitivity reaches 0.135 nm mm−1, and its horizontal counterparts along the positive and negative axes achieve 0.602 nm mm−1 and −0.572 nm mm−1, respectively.

A simple and effective means for fabricating gold hollow spheres with controllablegold particle size is presented, where polydiacetylene vesicles terminatedwith –NH2 were synthesized and used as templates for the fast combination of gold nanoparticles.The combination process of gold to the hollow ball and the subsequent particlereductive growth have been investigated using a quartz crystal microbalance,and the morphology and stability of these hollow spheres are characterized usingtransmission electron microscopy and ultraviolet–visible spectroscopy. This shows thatdifferent sizes of gold particles and a variety of coverage of gold nanoparticleson –NH2-terminated spheres could be easily controlled. The as-prepared gold hollow ball has anexcellent ability against mechanical disturbance and the nanogolds on it have veryhigh stability against aggregation and ageing. The immobilization effect of asingle-strand DNA probe shows that gold nanoparticles on the surface of this kindof sphere have a great advantage over their counterparts on a planar substratesurface.

Objective: To construct a sizeable naive human Fab phage display antibody library to screen high-affinity specific antibodies in vitro . Methods: Total RNA was extracted from peripheral blood mononuclear cells (PBMCs) of 126 healthy individuals, subsequently reverse-transcribed into cDNA, and used as a template. PCR amplification was performed to obtain the V H from IgG, IgM and light chain κ, λ, separately, with the initial PCR products serving as templates for a second round of PCR. Overlap extension PCR was employed to generate fragments of the κ and λ light chains. These fragments were ligated with the phage vector pNC3, which harbors the variable region 1 of the heavy chain, to construct a recombinant phage plasmid. This plasmid was then electroporated into competent Escherichia Coli TG1 cells to establish a naive human Fab phage display antibody library. One hundred clones were randomly selected for identification and sequencing, and antibody gene polymorphisms were analyzed using the IMGT database and MAFFT software. Recombinant α-hemolysin from Staphylococcus aureus was utilized to screen Fab antibody fragments through biopanning of the antibody library, followed by random selection of phage ELISA-identified clones. The positive clones (antigen A 450 ∶blank control A 450 ≥2.1) were sequenced. Results: Two large naive Fab phage display antibody libraries were successfully constructed, in which the capacity of κ and λ chain antibody libraries were 1.25×10 11 and 1.54×10 11 , respectively. The titers for two antibody libraries were 6.04×10 13 CFU/ml and 3.50×10 13 CFU/ml. The positive transformation insertion rates for κ and λ chain antibody libraries were 96% (96/100) and 100% (100/100), respectively. Sequence analysis revealed that all antibody sequences were unique. The amino acid sequences in the skeletal region were relatively conserved. In contrast, significant variations in the length of the complementarity determining region (CDR) were found, and the diversity of amino acid sequence of the complementary determining region was high, especially the CDR3. Analysis using the IMGT database indicated that the sequences exhibited a broad distribution across variable-diversity-joining gene families. After six rounds of panning, specific phage antibodies enrichment targeting α-hemolysin were achieved. A total of 142 monoclonal antibodies were sequenced, yielding 8 distinct Fab antibody sequences. Conclusion: This study successfully constructed two naive human Fab phage display antibody libraries with large capacity and good diversity, which can be used for screening human antibodies for serum epidemiology.

Introduction: The COVID-19 pandemic posed a threat to public health and psychological functioning, with early studies documenting higher rates of psychopathology within the United States and globally. Hope and optimism promote adjustment and are associated with positive physical and mental health outcomes. Thus, individual differences in hope and optimism may also foster resilience during a global health crisis., Aims: The current study examined how hope and optimism influenced longitudinal health-focused distress and wellbeing during the pandemic., Methods: Data were collected from 788 American adults across three periods during Spring-Summer 2020 using MTurk. Latent growth curve modeling examined whether hope and optimism predicted COVID stress, health anxiety, and wellbeing trajectories., Results: COVID stress and health anxiety decreased after the onset of the pandemic, whereas wellbeing was stable. Individually, hope and optimism predicted lower initial COVID stress and health anxiety, along with greater initial wellbeing. When examining the combined influence of hope and optimism, optimism was more strongly related to health-focused distress, though both were strong predictors of wellbeing., Conclusions: These findings indicate that Americans were resilient and positive expectancies, particularly optimism, predicted better initial adjustment to the early phases of the pandemic. Thus, positive expectancies appear to be protective during a global health crisis., (© 2024 Wiley Periodicals LLC.)

Strengths use, the engagement of positive character traits in everyday contexts, is associated with both positive functioning and symptom reduction. The present study examined longitudinal relationships between strengths use and emotional disorder symptoms (anxiety, stress, and depression) during a randomized clinical trial of the Digital Unified Protocol, a transdiagnostic cognitive behavioral therapy. Participants (N = 120) completed assessments at four major time points during treatment and at 3-month follow-up. We specified three random-intercept cross-lagged panel model to capture within-person, bidirectional, time-lagged relationships between strengths use and anxiety, stress, and depression, respectively. Prospective increases in strengths use were associated with significant decreases in anxiety at all time points (β = -0.26 to -0.49), while prospective decreases in anxiety were associated with significant increases in strengths use at most time points (β = -0.25 to -0.36). Prospective increases in strengths use were associated with significant decreases in stress at most time points (β = -0.23 to -0.54), while prospective decreases in stress were associated with significant increases in strengths use at Week 4 (β = -0.21) and at follow-up (β = -0.41). Prospective increases in strengths use were associated with significant decreases in depression at Week 8 (β = -0.63) and at posttreatment (β = -0.67), while prospective decreases in depression were associated with significant increases in strengths use at most time points (β = -0.34 to -0.47). Clinical implications of findings are discussed, including the potential role of strengths use as a treatment target. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Before the development of the Unified Protocol for the Transdiagnostic Treatment of Emotional Disorders (UP), evidence-based treatment options for commonly co-occurring anxiety, mood, and related disorders consisted of numerous single-disorder protocols that shared many similarities, reflecting the overlap among these disorders themselves. The UP distilled common elements of cognitive behavioral protocols into a unified intervention directly targeting core temperamental features underlying these disorders of emotion, namely neuroticism and associated emotion dysregulation. The UP has since become a leading "transdiagnostic" treatment for emotional disorders, which is now available in several formats (e.g., individual, group, digital) and has accumulated a strong evidence base, leading to international implementation. There is now also research evidence that the UP can be flexibly applied to a range of clinical presentations, including borderline personality disorder, trauma- and stressor-related disorders, eating disorders, alcohol use disorder, and comorbid chronic physical health conditions. Yet additional research is needed to evaluate the UP in routine clinical settings, with more heterogeneous patient populations, and under circumstances that mirror actual clinical practice. Thus, we must also continue to explore the benefits of large-scale UP training initiatives and implementation in major healthcare systems., (Copyright © 2024 Association for Behavioral and Cognitive Therapies.

There is preliminary evidence that the anticonvulsant medication Zonisamide (ZON) may be an effective, well-tolerated treatment for alcohol use disorder (AUD). However, further evaluation of its efficacy for treating patients with AUD is needed, and much remains unknown about ZON's therapeutic mechanisms. The present study aimed to evaluate the efficacy and tolerability of ZON in a double-blind, placebo-controlled, randomized trial. Eighty-one adults (ages 21-65) diagnosed with AUD were randomly assigned to receive either ZON (at a target dose of 400 mg/d) or a pill placebo over 12 weeks, followed by a two-week taper. All participants also received a computerized alcohol reduction program, Take Control (TC). Primary drinking outcomes were average daily drinks, percentage drinking days, and percentage heavy drinking days. Further, we evaluated changes in AUD clinical severity and performance on neuropsychological measures. For both groups, drinking outcomes generally decreased, as did AUD clinical severity, though group differences were not statistically significant. Neuropsychological testing performance was similar for both groups at baseline; however, at post-treatment, participants in the ZON group demonstrated poorer working memory and lower performance on verbal fluency tests compared to the placebo group, and these differences were statistically significant with moderate-large effect sizes. One serious adverse event was reported among individuals receiving ZON. Study findings indicate that ZON combined with TC does not demonstrate superior effectiveness for reducing average daily drinks in this clinical sample with principal AUD compared to placebo and TC, and treatment with ZON may be associated with reduced neurocognitive performance over time., Competing Interests: Declaration of competing interest Todd J.

Chronic wasting disease (CWD) is a fatal prion disease of cervids that has spread across much of North America. Although gold standard CWD diagnostics involve postmortem testing of medial retropharyngeal lymph nodes or obex (brain stem), a key tissue sample for antemortem testing is rectoanal mucosa-associated lymphoid tissue (RAMALT). However, collection of an adequate sample (i.e., enough lymphoid follicles) may be affected by factors such as deer age, repeated sampling, skill of the sampler, and adverse conditions during collection. Here, we document the protocol used to train personnel for RAMALT collection in a large study of free-ranging white-tailed deer (Odocoileus virginianus) in Wisconsin, USA, and determine factors that contributed to the occurrence of inadequate RAMALT samples. Our training protocol included hands-on experience with postmortem tissues, as well as a mentored collection process in the field. Collection of RAMALT under field conditions was highly successful, with 763/806 (94.7%) samples deemed adequate for subsequent testing. Although inadequate samples were rare, they were more likely to occur with older deer and when samples were collected at dusk (i.e., limited ambient lighting). We conclude that RAMALT collection can be highly successful under adverse field conditions, including with technicians with limited prior veterinary experience, and we provide details of our training program to facilitate repeatability in other antemortem CWD testing efforts., (© Wildlife Disease Association 2024.)

Digital supplements to tele-psychotherapy are increasingly needed. The purpose of this retrospective study was to investigate the association between outcomes and the use of supplemental video lessons based on the Unified Protocol (UP), an empirically supported transdiagnostic treatment., Participants included 7,326 adults in psychotherapy for depression and/or anxiety. Partial correlations were calculated between number of UP video lessons completed and change in outcomes after 10 weeks, controlling for number of therapy sessions and baseline scores. Then, participants were divided into those who did not complete any UP video lessons ( n  = 2355) and those who completed at least 7/10 video lessons ( n  = 549), and propensity-matched on 14 covariates. Repeated measures analysis of variance compared these groups ( n  = 401 in each group) on outcomes., Among the entire sample, symptom severity decreased as the number of UP video lessons completed increased, with the exception of lessons on avoidance and exposure. Those watching at least 7 lessons showed significantly greater reduction in both depression and anxiety symptoms than those who did not watch any., Viewing supplemental UP video lessons in addition to tele-psychotherapy had a positive and significant association with symptom improvement and may provide an additional tool for clinicians to implement UP components virtually.

The present study expands on the growing body of research on the effects of cognitive behavioral therapy (CBT) on positive affect. More specifically, we explore how CBT may promote increases in the Joviality subscale of the Positive and Negative Affect Schedule-Expanded Form (PANAS-X), a measure of self-rated affect that captures positive emotions, including joy and excitement, and how change in joviality may be associated with concurrent symptom change. We utilized data from a randomized equivalence trial comparing the efficacy of the unified protocol (UP) for transdiagnostic treatment of emotional disorders, a transdiagnostic CBT, against various well-established single disorder protocols (SDP) and waitlist control. First, we generated affect profiles for patients receiving CBT (either UP or SDP) or waitlist control, based on their baseline and posttreatment positive affect (PA) and negative affect (NA), compared with a clinical reference sample. We found that the affect profile for most patients receiving CBT shifted from high NA/low PA to low NA/high PA. Further, participants receiving CBT were more likely than individuals in the waitlist control to achieve this outcome. We then examined the PANAS-X Joviality subscale, which has been subject to very limited previous research. Change in joviality was associated with improvement in symptoms of both anxiety ( B = -0.81, p = .00) and depression ( B = -0.94, p = .00). Joviality increased more rapidly in individuals with more severe anxiety but not severe depression. We discuss the possible clinical implications of these preliminary results, including the role of treatment innovations incorporating a focus on increasing positive affect, particularly the emotions associated with joviality, while simultaneously decreasing negative affect.

In 2017, Hurricane Harvey flooded more than 300,000 buildings causing an estimated $125 billion in damages and resulting in 68 deaths (National Hurricane Center). This actual or threatened loss of life and physical harm led many to report negative effects on mental well-being and greater mental illness. However, many individuals have been able to experience similar adverse events without a significant negative impact on their mental health and well-being. Positive thinking factors such as hope, optimism, and self-efficacy have been proposed as protective factors in the face of difficult life events. Hope, optimism, and self-efficacy are related but distinct constructs that have often been studied separately, but whose unique impact on well-being and mental illness is less clear, especially in the context of a natural hazard. The current study uses structural equation modeling to measure the unique contribution of hope, optimism, and hurricane-coping self-efficacy on mental well-being and mental illness in a community sample of 300 subjects who experienced Hurricane Harvey, recruited from Mechanical Turk., (© 2023 Wiley Periodicals LLC.)

Objective: To understand the population structure of food-borne Staphylococcus (S.) aureus in China. Methods: Whole genome sequencing was used to analyze 763 food-borne S. aureus strains from 16 provinces in China from 2006 to 2020. Multilocus sequence typing (MLST), staphylococcal protein A gene ( spa ) typing, and staphylococcal chromosome cassettemec (SCC mec ) typing were conducted, and minimum spanning tree based on ST types (STs) was constructed by BioNumerics 7.5 software. Thirty-one S. aureus strains isolated from imported food products were also included in constructing the genome phylogenetic tree. Results: A total of 90 STs (20 novel types) and 160 spa types were detected in the 763 S. aureus isolates. The 72 STs (72/90, 80.0%) were related to 22 clone complexes. The predominant clone complexes were CC7, CC1, CC5, CC398, CC188, CC59, CC6, CC88, CC15, and CC25, accounting for 82.44% (629/763) of the total. The STs and spa types in the predominant clone complexes changed over the years. The methicillin-resistant S . aureus (MRSA) detection rate was 7.60%, and 7 SCC mec types were identified. The ST59-t437-Ⅳa (17.24%, 10/58), ST239-t030-Ⅲ (12.07%, 7/58), ST59-t437-Ⅴb (8.62%, 5/58), ST338-t437-Ⅴb (6.90%, 4/58) and ST338-t441-Ⅴb (6.90%, 4/58) were the main types in MRSA strains. The genome phylogenetic tree had two clades, and the strains with the same CC, ST, and spa types clustered together. All CC7 methicillin sensitive S. aureus strains were included in Clade1, while 21 clone complexes and all MRSA strains were in Clade2. The MRSA strains clustered according to the SCC mec and STs. The strains from imported food products in CC398, CC7, CC30, CC12, and CC188 had far distances from Chinese strains in the tree. Conclusions: In this study, the predominant clone complexes of food-borne strains were CC7, CC1, CC5, CC398, CC188, CC59, CC6, CC88, CC15, and CC25, which overlapped with the previously reported clone complexes of hospital and community-associated strains in China, suggesting that close attention needs to be paid to food, a vehicle of pathogen transmission in community and food poisoning.

Objective: The docking and superantigen activity sites of staphylococcal enterotoxin-like W (SElW) and T cell receptor (TCR) were predicted, and its SElW was cloned, expressed and purified. Methods: AlphaFold was used to predict the 3D structure of SElW protein monomers, and the protein models were evaluated with the help of the SAVES online server from ERRAT, Ramachandran plot, and Verify_3D. The ZDOCK server simulates the docking conformation of SElW and TCR, and the amino acid sequences of SElW and other serotype enterotoxins were aligned. The primers were designed to amplify selw , and the fragment was recombined into the pMD18-T vector and sequenced. Then recombinant plasmid pMD18-T was digested with BamH Ⅰand Hind Ⅲ. The target fragment was recombined into the expression plasmid pET-28a(+). After identification of the recombinant plasmid, the protein expression was induced by isopropyl-beta-D- thiogalactopyranoside. The SElW expressed in the supernatant was purified by affinity chromatography and quantified by the BCA method. Results: The predicted three-dimensional structure showed that the SElW protein was composed of two domains, the amino-terminal and the carboxy-terminal. The amino-terminal domain was composed of 3 α-helices and 6 β-sheets, and the carboxy-terminal domain included 2 α-helices and 7 antiparallel β-sheets composition. The overall quality factor score of the SElW protein model was 98.08, with 93.24% of the amino acids having a Verify_3D score ≥0.2 and no amino acids located in disallowed regions. The docking conformation with the highest score (1 521.328) was selected as the analysis object, and the 19 hydrogen bonds between the corresponding amino acid residues of SElW and TCR were analyzed by PyMOL. Combined with sequence alignment and the published data, this study predicted and found five important superantigen active sites, namely Y18, N19, W55, C88, and C98. The highly purified soluble recombinant protein SElW was obtained with cloning, expression, and protein purification. Conclusions: The study found five superantigen active sites in SElW protein that need special attention and successfully constructed and expressed the SElW protein, which laid the foundation for further exploration of the immune recognition mechanism of SElW.

Background: Exposure-based therapy is an effective first-line treatment for anxiety-, obsessive-compulsive, and trauma- and stressor-related disorders; however, many patients do not improve, resulting in prolonged suffering and poorly used resources. Basic research on fear extinction may inform the development of a biomarker for the selection of exposure-based therapy. Growing evidence links orexin system activity to deficits in fear extinction and we have demonstrated that reactivity to an inhaled carbon dioxide (CO 2 ) challenge-a safe, affordable, and easy-to-implement procedure-can serve as a proxy for orexin system activity and predicts fear extinction deficits in rodents. Building upon this basic research, the goal for the proposed study is to validate CO 2 reactivity as a biomarker of exposure-based therapy non-response., Methods: We will assess CO 2 reactivity in 600 adults meeting criteria for one or more fear- or anxiety-related disorders prior to providing open exposure-based therapy. By incorporating CO 2 reactivity into a multivariate model predicting treatment non-response that also includes reactivity to hyperventilation as well as a number of related predictor variables, we will establish the mechanistic specificity and the additive predictive utility of the potential CO 2 reactivity biomarker. By developing models independently within two study sites (University of Texas at Austin and Boston University) and predicting the other site's data, we will validate that the results are likely to generalize to future clinical samples., Discussion: Representing a necessary stage in translating basic research, this investigation addresses an important public health issue by testing an accessible clinical assessment strategy that may lead to a more effective treatment selection (personalized medicine) for patients with anxiety- and fear-related disorders, and enhanced understanding of the mechanisms governing exposure-based therapy., Trial Registration: ClinicalTrials.gov Identifier: NCT05467683 (20/07/2022)., (© 2022.

This paper reviews the present literature examining how hope relates to PTSD and broader functioning after a trauma, including potential underlying mechanisms and significant factors impacting these relationships and the role of hope as a mechanism of change within interventions for PTSD. First, the ways in which trauma impacts hope are discussed. Afterwards, an overview is provided of cross-sectional and prospective research indicating that greater hope reduces the risk of PTSD and promotes positive outcomes of adversity. Next, potential underlying mechanisms and determinants of the relationship between hope and adjustment are explored, including adaptive appraisals, productive coping, and social support. Finally, evidence supporting the role of hope as a mechanism of change in treatments for PTSD is reviewed., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

Background: Line probe assays (LPAs) are PCR-based assays used for the rapid diagnosis of Mycobacterium tuberculosis (MTB) and drug-resistant tuberculosis (DR-TB). But studies on its performance are insufficient. Thus, in this study, we conducted a systematic review and meta-analysis to evaluate the effect of LPAs in the detection of MTB and drug-resistant TB in comparison with the traditional culture and DST methods., Methods: A systemic literature search was conducted on the Web of Science, Embase, PubMed, the Cochrane Library, Scopus, and OVID databases. All the included studies were classified according to different detecting objects. Sensitivity, specificity, Positive Likely Ratio (PLR), Negative Likely Ratio (NLR), Diagnostic Odds Ratio (DOR), corresponding 95% confidence interval, Area Under Curve (AUC), Deeks' funnel plot, and Bivariate Boxplot was used to do the evaluation., Results: 147 studies included 491 datasets, with 182,448 samples, were incorporated into our analysis. The sensitivity (95% CI), specificity (95% CI), PLR, NLR, DOR and AUC for MTB were 0.89 (0.86 to 0.92), 0.94 (0.90 to 0.97), 15.70, 0.11, 139 and 0.96, respectively; for rifampicin-resistant TB were 0.96 (0.95 to 0.97), 0.99 (0.98 to 0.99), 82.9, 0.04, 1994 and 1.00, respectively; for isoniazid-resistant TB were 0.91 (0.89 to 0.93), 0.99 (0.98 to 0.99), 83.4, 0.09, (0.99 to 1.00), 195.7, 0.07, 2783 and 1.00, respectively; for Multi-drug resistant TB (MDR-TB) were 0.93 (0.90 to 0.95), 1.00 (0.99 to 1.00), 195.7, 0.07, 2783 and 1.00, respectively; for extensively drug-resistant TB (XDR-TB) were 0.60 (0.33 to 0.82), 1.00 (0.95 to 1.00), 291.3, 0.4, 726 and 0.95, respectively; for (second-line drug-resistant TB) SLID-TB were 0.83 (0.78 to 0.87), 0.98 (0.97 to 0.99), 44.6, 0.17, 262 and 0.98, respectively. Sensitivity in pre-extensively drug-resistant TB (Pre-XDR-TB) was 0.67, specificity was 0.91. No publication bias existed according to Deeks' funnel plot., Conclusion: High diagnosis performance was confirmed in LPAs for the diagnosis of MTB and drug-resistant TB. LPAs might be a good alternative to culture and DST in detecting MTB, RR-TB, INH-TB, XDR-TB, SLID-TB, and MDR-TB. While more studies were still needed to explore the diagnosis performance of LPAs for Pre-XDR TB., (Copyright © 2022. Published by Elsevier B.V.)

Background: Staphylococcus aureus can cause many diseases and even death. It's important to detect Staphylococcus aureus rapidly and reliably. The accuracy of a novel test named LAMP in detecting Staphylococcus aureus is unclear. Therefore, a systematic review and meta-analysis were conducted to evaluate the accuracy of the LAMP assay for Staphylococcus aureus detection., Methods: Four databases were searched for relevant studies. Meta-DiSc 1.4.0 and Stata 12.0 were used for statistical analysis. At the same time, we used QUADAS-2 to assess the studies we included. Two groups of subgroup analysis were done to differentiate the diagnostic effects of various LAMP tests and in cases of different gold standards., Results: 11 studies were identified and 19 2 × 2 contingency tables were extracted in our study. The results showed that both pooled sensitivity and specificity of the LAMP assay were 99% (95% CI 99-100)., Conclusion: The LAMP assay demonstrated high sensitivity and specificity in diagnosing Staphylococcus aureus., (© 2022.

Background: GeneXpert enterovirus Assay is a PCR-based assay for Enterovirus meningitis diagnosis. However, there is currently no research about the performance of GeneXpert enterovirus assay in the diagnosis of enterovirus meningitis. Thus, a systematic review and meta-analysis is significant on the topic., Methods: Embase, Cochrane Library, Web of Science, and PubMed were systematically reviewed with retrieval types. Some criteria were used to filter the studies. Only studies published in English, that made a comparison between GeneXpert enterovirus assay and RT-PCR, and could be formulated in a 2*2 table, were included. The quality of the included studies was evaluated by QUADAS-2. The effect of the GeneXpert enterovirus assay was assessed by the Sensitivity, Specificity, Positive Likelihood Ratio, Negative Likelihood Ratio, Diagnosis Odds Ratio, and summary receiver operating characteristic (SROC) curve. Publication bias and heterogeneity were evaluated by the Deeks' funnel test and Bivariate Box plot respectively., Results: 7 studies were recruited in the analysis. The Pooled Sensitivity was 0.96 [95% CI (0.94-0.97)], Pooled Specificity was 0.99 [95% CI (0.98-0.99)], Positive Likelihood Ratio was 130.46 [95% CI (35.79-475.58)], Negative Likelihood Ratio was 0.04 [95% CI (0.02-0.10)], and Diagnostic Odds Ratio was 3648.23 (95% CI [963.99-13,806.72)]. In SROC Curve, Area Under Curve (AUC) was 0.9980, and Q*= 0.9849. In Deeks' funnel test, the P-value was 0.807 (P > 0.05), indicating no publication bias. The Bivariate Box plot indicated no evident heterogeneity., Conclusions: The GeneXpert enterovirus assay demonstrated high diagnostic accuracy in diagnosing enterovirus meningitis., (© 2022.

The Genomics Education Partnership (GEP) engages students in a course-based undergraduate research experience (CURE). To better understand the student attributes that support success in this CURE, we asked students about their attitudes using previously published scales that measure epistemic beliefs about work and science, interest in science, and grit. We found, in general, that the attitudes students bring with them into the classroom contribute to two outcome measures, namely, learning as assessed by a pre- and postquiz and perceived self-reported benefits. While the GEP CURE produces positive outcomes overall, the students with more positive attitudes toward science, particularly with respect to epistemic beliefs, showed greater gains.

A Gram-stain-positive, aerobic, non-pigmented and non-motile actinobacterium, designated strain SCSIO 67246 T , was isolated from a stony coral sample collected from the Sanya sea area, Hainan province, China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SCSIO 67246 T shared the highest similarities with Nocardioides rotundus MCCC 1A10561 T (96.5 %) and Nocardioides sonneratiae KCTC 39565 T (96.1%). The novel strain grew at 15-37 °C, at pH 5.0-10.0 and in the presence of 0-10 % (w/v) NaCl. The genome length of strain SCSIO 67246 T was 3.52 Mbp with a DNA G+C content of 72.0 mol% and 3397 protein-coding genes. The novel strain showed an average nucleotide identity value of 76.5 % and a digital DNA-DNA hybridization value of 20.1 % with N. rotundus MCCC 1A10561 T . Strain SCSIO 67246 T contained MK-8(H 4 ) as the major menaquinone. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and five phospholipids. The major cellular fatty acids were iso-C 16 : 0 , C 17 : 1 ω 8 c and summed feature 9 (iso-C 17 : 1 ω 9 c /10-methyl C 16 : 0 ). ll-2,6-Diaminopimelic acid was the diagnostic diamino acid. The whole-cell sugars were galactose, glucose and ribose. Based on this polyphasic taxonomic study, strain SCSIO 67246 T represents a novel species of the genus Nocardioides , for which the name Nocardioides coralli sp. nov. is proposed. The type strain is SCSIO 67246 T (=MCCC 1K06251 T =KCTC 49719 T ).

The COVID-19 pandemic has had an adverse effect on anxiety and depression symptoms and disorders in the United States and worldwide. As such, there is considerable interest in better understanding the relationship between COVID-19 and anxiety and depressive disorders. Although individual differences in perceived stress have shown to be related to anxiety and depression in non-COVID-19 work, research has not examined potential factors underlying this relation in the context of COVID-19. Fatigue severity may be a promising mechanistic construct for perceived stress and anxiety and depression relations, as some work has found that perceived stress may predict elevated fatigue symptoms. As such, the current study sought to examine the potential explanatory role of fatigue severity in the relation between COVID-19 specific perceived stress and depression, anxiety, and panic symptoms among 563 adults (41.9% female, M age  =  38.26 years, SD  = 12.15). Results suggested that COVID-19 perceived stress, via fatigue severity, significantly predicted depression, anxiety, and panic symptoms. These results provide initial empirical support for the role of fatigue severity in the relation between COVID-19 perceived stress and depression, anxiety, and panic symptoms. Future work would benefit from using longitudinal data to evaluate the current model.

Background: The COVID-19 pandemic has had a profound impact on health and well-being worldwide. There is increasing research seeking to better understand the psychological impact of COVID-19 experiences. However, this research has largely been limited in size and scope., Methods: The present study examined longitudinal trajectories of COVID-19 experiences on COVID-19 related stress, anxiety, depression, and functional impairment in a convenience sample of 788 American adults recruited through MTURK. Data was collected across four waves between March and October 2020., Results: COVID-19 experiences were consistently associated with higher odds of probable anxiety and depression diagnoses. COVID-19 related stress also predicted large proportions of variance in anxiety, depression, and functional impairment in latent variable analyses. Overtime, the results indicated that while anxiety and depression decreased, functional impairment remained stable., Conclusions: These findings highlight the emotional toll of the COVID-19 pandemic over time. Decreases in COVID-19 related stress, anxiety, and depression over time may reflect resiliency among respondents. Importantly, these results underscore the continued need for mental health services as associations between COVID-19 and functional impairment remained consistent over time., Competing Interests: Conflict of interestMatthew W.

A novel thermophilic bacterium, designated SCSIO 07484 T , was isolated from marine sediment sampled in the South China Sea. Growth occurred at 30-60 °C, pH 6.0-8.0 and in the presence of 0-3 % (w/v) NaCl. Cells of strain SCSIO 07484 T were rod-shaped and flagellum-forming. No soluble pigment was observed. The phylogenetic analysis of the 16S rRNA gene sequences indicated that SCSIO 07484 T belonged to the family Paenibacillaceae and clustered with members of the genus Brevibacillus in the phylogenetic trees with less than 96.2 % similarities. The cell wall contained meso -diaminopimelic acid. Whole-cell hydrolysates contained arabinose, glucose and ribose. The predominant menaquinone was MK-7. Major fatty acids were iso-C 16 : 0 , iso-C 15 : 0 , C 16 : 0 and iso-C 14 : 0 . Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylmonomethylethanolamine were its diagnostic polar lipids. The whole genome size of strain SCSIO 07484 T was 4 079 826 bp with a DNA G+C content of 56.2 mol%, including one circular chromosome of 3 978392 bp and one plasmid of 101434 bp. Based on the polyphasic analysis of strain SCSIO 07484 T , it is considered to represent a novel species of the genus Brevibacillus , for which the name Brevibacillus marinus sp. nov. is proposed with the type strain SCSIO 07484 T (=DSM 106769 T =CGMCC 1.15814 T ).

Objective: To examine the association between hip and knee osteoarthritis (OA) and falls. Potentially relevant articles that examine the association between hip, knee, radiological, and self-reported OA and falls were retrieved from PubMed, EMBASE, Scopus, and Web of Science up until March of 2020., Methods: The pooled risk ratios (RRs) as well as their related 95% confidence intervals (CIs) were calculated. Statistic and subgroup analyses were performed. A total of 21 studies involving 146 965 participants were included., Results: No association was found between hip OA and falls. The pooled RRs value suggested a higher prevalence of falls in knee OA patients (RR = 1.35, 95% CI: 1.20 to 1.51, P < .00001) and self-reported OA (RR = 1.33, 95% CI: 1.23 to 1.45, P < .00001) than in non-OA subjects. The pooled RR value suggested no difference between prevalence of falls in radiological OA patients compared to non-OA subjects (RR = 1.82, 95% CI: 0.89 to 3.73, P = .10). Both radiological and self-reported knee OA seem to be positively associated with falls, while no obvious association was found between hip OA and falls., Conclusions: Therefore, knee OA is a risk factor for falls which should be closely monitored., (© 2021 John Wiley & Sons Ltd.)

Two novel marine actinobacteria, designated as SCSIO 60955 T and SCSIO 61214 T , were isolated from deep-sea sediment samples collected from the South China Sea. The cells of these organisms stained Gram-negative and were rod shaped. These strains were aerobic, and catalase- and oxidase-positive. Optimal growth occurred at 28 °C and pH 7 over 14 days of cultivation. Both strains possessed phospholipids and phosphoglycolipids. The main menaquinone was MK-7. The major fatty acid was C 16:0 . The peptidoglycan structure was type A1γ' (meso-Dpm). Analysis of genome sequences revealed that the genome size of SCSIO 60955 T was 3.37 Mbp with G + C content of 76.1%, while the genome size of SCSIO 61214 T was 3.67 Mbp with a G + C content of 74.8%. The ANI and 16S rRNA gene analysis results showed that the pairwise similarities between the two strains were 73.4% and 97.7% and that with other recognized Thermoleophilia species were less than 69.1% and 87.8%, respectively. Phylogenetic analysis of the 16S rRNA gene sequences showed that strains SCSIO 60955 T and SCSIO 61214 T were separately clustered together and formed a well-separated phylogenetic branch distinct from their most related neighbor Gaiella occulta. Based on the data presented here, these two strains are proposed to represent two novel species of a novel genus, for which the name Miltoncostaea marina gen. nov., sp. nov., with the type strain SCSIO 60955 T (=DSM 110281 T =CGMCC 1.18757 T ), and Miltoncostaea oceani sp. nov., with the type strain SCSIO 61214 T (=KCTC 49527 T =CGMCC 1.18758 T ) are proposed. We also propose that these organisms represent a novel family named Miltoncostaeaceae fam. nov. of a novel order Miltoncostaeales ord. nov., (Copyright © 2021 Elsevier GmbH. All rights reserved.)

Actinobacteria are ubiquitous in marine ecosystems, and they are regarded as an important, underexplored, potential pharmaceutical resource. The orders Gaiellales and Rubrobacterales are deep taxonomic lineages of the phylum Actinobacteria, both are represented by a single genus and contain only a few species. Although they have been detected frequently by high-throughput sequencing, their functions and characteristics in marine habitats remain unknown due to the lack of indigenous phenotypes. Here, we investigated the status of the orders in South China Sea (SCS) sediments using culture-independent and culture-dependent methods. Gaiellales is the second-most abundant order of Actinobacteria and was widely distributed in SCS sediments at water depths of 42-4,280 m, and four novel marine representatives in this group were successfully cultured. Rubrobacterales was present at low abundance in energy-limited marine habitats. An isolation strategy for Rubrobacterales from marine samples was proposed, and a total of 138 mesophilic Rubrobacterales strains were isolated under conditions of light and culture time combined with high-salinity or low-nutrient media. Marine representatives recovered in this study formed branches with a complex evolutionary history in the phylogenetic tree. Overall, the data indicate that both Gaiellales and Rubrobacterales can adapt to and survive in extreme deep-sea environments. This study lays the groundwork for further analysis of the distribution and diversity of the orders Gaiellales and Rubrobacterales in the ocean and provides a specific culture strategy for each group. The results open a window for further research on the ecological roles of the two orders in marine ecosystems., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Chen, He, Cui, Li, Shi, Long and Tian.)

Hope is a cognitive trait that predicts both resilience to and recovery from anxiety and stress-related disorders. The present study examines the prospective associations of hope with subsequent anxiety, stress, and well-being during the COVID-19 pandemic. Perceived emotional control, a transdiagnostic vulnerability factor, was also examined as a potential mediator of these relationships. American adults ( N = 822) were recruited during the COVID-19 pandemic using Amazon mTURK and structural equation modeling was used to examine how trait hope predicted outcomes approximately one month later. Higher hope was associated with greater well-being and perceived emotional control, as well as lower levels of anxiety and COVID-19 perceived stress. Results also indicated an indirect effect of hope with all outcomes via perceived emotional control. These findings suggest that hope may associated with resilience to the chronic stressors associated with the COVID-19 pandemic.

Background: The COVID-19 pandemic has had a profound negative impact on mental health symptoms and daily life functioning across the United States and worldwide. Past work has revealed that perceived stress relates to poorer outcomes, however, little work to date has examined factors that may exacerbate these outcomes, and no work to date has examined this relation in terms of COVID-19. Anxiety sensitivity is a promising individual difference factor that has shown to be related to mental health and functional impairment. Anxiety Sensitivity is also a vulnerability factor related to heightened stress perception., Method: Therefore, the current study sought to examine the potential moderating role of anxiety sensitivity in the relation between COVID-19 specific perceived stress and global anxiety symptom severity, anxious arousal symptom severity, and functional impairment among 563 adults (58.1% male; M age  = 38.3 years; SD  = 12.15)., Results: Results indicated a statistically significant interaction between COVID-19 perceived stress and anxiety sensitivity with global anxiety symptom severity, anxious arousal symptom severity, and functional impairment. Post-hoc analysis indicated that COVID-19 perceived stress was associated with an increased likelihood of clinically significant global anxiety symptom severity and anxious arousal symptom severity at higher levels of anxiety sensitivity., Conclusions: The current study provides support for the role of anxiety sensitivity in identifying individuals at risk for clinically significant global anxiety symptom severity and anxious arousal symptom severity., Competing Interests: Conflicts of InterestKara Manning, Natasha D.

Natural disasters can lead to mental health problems, such as posttraumatic stress disorder (PTSD). Higher levels of loss and/or disruption and prior trauma exposure constitute risk factors for mental illness, whereas protective factors, including hope and resilience, support positive functioning. The present cross-sectional study used structural equation modeling to examine the relative influence of resilience and hope on mental health and well-being 1-3 months after Hurricane Harvey made landfall in August 2017, among a sample of 829 adults in the Greater Houston, Texas area. Resilience was more strongly associated with reduced PTSD symptoms, β = -.31, 95% CI [-.42, -.21], than was hope, β = -.17, 95% CI [-;.30, -.04], whereas hope was more strongly associated with components of well-being, βs = .47-.63. Hope was positively associated with posttraumatic growth, β = .30, 95% CI [.19, .41], whereas resilience was negatively associated with posttraumatic growth, β = -.24, 95% CI [-.35, -.12]. These associations remained consistent after considering risk factors, although more variance in trauma-related outcomes was risk factors were included in the model. The present results suggest that considering the influence of both risk and resilience factors provides an enhanced picture of postdisaster mental health., (© 2020 International Society for Traumatic Stress Studies.)

Two novel Gram-stain-positive bacteria, designated as SCSIO 52909 T and SCSIO 52915 T , were isolated from a deep-sea sediment sample collected at about 3448 m water depth of the South China Sea. Phenotypic, chemotaxonomic and genomic characteristics were investigated. These strains were aerobic and tested positive for catalase activity, oxidase activity and nitrate reduction. Optimal growth occurred at 28 °C, pH 7 and 3% salinity over 14 days cultivation. Its peptidoglycan structure was type A3α (l-Lys-l-Ala) and the only menaquinone was MK-8. Both strains possessed diphosphatidylglycerol, phosphatidylglycerol, an unidentified phosphoglycolipid, an unidentified glycolipid and an unidentified phospholipid. Their major fatty acids differed, but both contained iso-branched components of C 16 : 0 12-methyl. Genome sequencing revealed two large genomes of 4.58 Mbp with G+C content of 67.0 mol% in SCSIO 52909 T and of 4.42 Mbp with G+C content of 69.1 % in SCSIO 52915 T . The two novel strains encoded genes for metabolism that are absent in most other Rubrobacter species, and possessed many more gene copy numbers of alkaline phosphatase and thioredoxin reductase. Results of gANI and 16S rRNA gene analyses suggested that the two strains represent two new species, with 74.9, 95.0 % pairwise similarity between each other, and less than 74.3 and 93.5 % to other recognized Rubrobacter species, respectively. In the phylogenetic analysis, strains SCSIO 52909 T and SCSIO 52915 T were separately clustered together and formed a well-separated phylogenetic branch distinct from the other known species in the genus Rubrobacter . Based on the data presented here, these two strains should be recognized as two new species in the genus Rubrobacter , for which the names Rubrobacter tropicus sp. nov., with the type strain SCSIO 52909 T (=KCTC 49412 T =CGMCC 1.13853 T ), and Rubrobacter marinus sp. nov., with the type strain SCSIO 52915 T (=KCTC 49411 T =CGMCC 1.13852 T ), are proposed.

Cognitive behavioral therapy (CBT) has been found to be very effective in reducing many forms of mental illness, but much less is known about whether CBT also promotes mental health or well-being. The goals of the present study were to (a) quantify the magnitude and timing of changes in overall well-being and specific facets of well-being during different CBTs for anxiety disorders, (b) determine whether these effects vary across transdiagnostic and disorder-specific CBT, and (c) examine how changes in well-being during treatment relate to changes in anxiety. A total of 223 adults (55.6% female, Mage = 31.1 years) were randomized to 1 of 5 CBT protocols for anxiety disorders at an outpatient clinic. Analyses included standardized mean gain effect sizes (ESsg) and latent growth curve modeling. Moderate-to-large increases in overall well-being and the 3 components of subjective, psychological, and social well-being were observed, mainly during the second half of CBT, and these increases were maintained at a 6-month follow-up. The magnitude of effects was comparable for transdiagnostic and disorder-specific CBT protocols and greater than in the waitlist condition. Parallel process latent growth curve models indicated that trajectories of change in well-being across treatment were strongly correlated with trajectories of change in clinician-rated and self-reported anxiety. Together, these findings suggest that different CBT protocols for anxiety consistently produce robust and lasting changes in well-being, and these changes are strongly linked to changes in anxiety during treatment.

Enzyme promiscuity is critical to the acquisition of evolutionary plasticity in cells and can be recruited for high-value chemical synthesis or xenobiotic degradation. The molecular determinants of substrate ambiguity are essential to this activity; however, these details remain unknown. Here, we performed the directed evolution of a prolidase to enhance its initially weak paraoxonase activity. The in vitro evolution led to an unexpected 1,000,000-fold switch in substrate selectivity, with a 30-fold increase in paraoxon hydrolysis and 40,000-fold decrease in peptide hydrolysis. Structural and in silico analyses revealed enlarged catalytic cavities and substrate repositioning as responsible for rapid catalytic transitions between distinct chemical reactions., (© 2020 Wiley Periodicals LLC.)

A novel marine actinobacterium, strain SCSIO 58843 T , was isolated from the sediment sample collected from the South China Sea. Strain SCSIO 58843 T was Gram-stain-positive, aerobic and rod shaped. The whole-cell hydrolysis of amino acids contained dd-DAP, alanine, glutamic acid, glycine and aspartic acid. The main menaquinone was MK-9(H 8 ). The major fatty acids were C 17 : 1   ω 8c and C 17 : 0 . The major phospholipids were diphosphatidylglycerol (DPG), phosphatidylinositol (PI), phospatidylcholine (PC) and phosphatidylinositolmannoside (PIM). The G+C content of the genomic DNA was 72.5 %. Phylogenetic analysis of the 16S rRNA gene sequences showed that strain SCSIO 58843 T formed a new lineage in the family Iamiaceae and had the highest similarity of 93.8 % with Iamia majanohamensis DSM 19957 T . Strain SCSIO 58843 T can be distinguished from these known genera in the family Iamiaceae by polyphasic data analyses, and represents a novel genus and novel species, for which Actinomarinicola tropica gen. nov., sp. nov is proposed with the type strain SCSIO 58843 T (=KCTC 49408 T =CGMCC 1.17503 T ).

Non-growing quiescent cells face special challenges when repairing lesions produced by exogenous DNA damaging agents. These challenges include the global repression of transcription and translation and a compacted chromatin structure. We investigated how quiescent yeast cells regulated the repair of DNA lesions produced by UV irradiation. We found that UV lesions were excised and repaired in quiescent cells before their re-entry into S phase, and that lesion repair was correlated with high levels of Rad7, a recognition factor in the global genome repair sub-pathway of nucleotide excision repair (GGR-NER). UV exposure led to an increased frequency of mutations that included C->T transitions and T > A transversions. Mutagenesis was dependent on the error-prone translesion synthesis (TLS) DNA polymerase, Pol zeta, which was the only DNA polymerase present in detectable levels in quiescent cells. Across the genome of quiescent cells, UV-induced mutations showed an association with exons that contained H3K36 or H3K79 trimethylation but not with those bound by RNA polymerase II. Together, the data suggest that the distinct physiological state and chromatin structure of quiescent cells contribute to its regulation of UV damage repair., Competing Interests: Declaration of Competing Interest None of the authors have any conflict of interests to report., (Copyright © 2020 The Author(s).

Objective: The present meta-analysis consolidated research examining how positive expectancies (e.g., hope, self-efficacy, and optimism) may protect against the development of posttraumatic stress disorder (PTSD)., Method: Articles were identified by searching PILOTS, PsycINFO, PubMed, and ProQuest Dissertations and Theses databases., Results: Aggregated results from 154 studies indicated that positive expectancies were associated with lower levels of PTSD symptoms. This relationship was stronger for coping-specific self-efficacy (k = 38, r = -.49; -.54 to -.43) and hope (k = 20, r = -.34; -.39 to -.28) compared with general self-efficacy (k = 45, r = -.25; -.30 to -.20) and optimism (k = 59, r = -.29; -.33 to -.25) when examining cross-sectional studies, and results were consistent in prospective studies. Age and gender did not moderate the cross-sectional relationships., Conclusions: These findings indicate that positive expectancies predict post-trauma resilience. Future research should identify moderators and examine positive expectancies as mechanisms of change in therapy., (© 2019 Wiley Periodicals, Inc.)

A hallmark of the research experience is encountering difficulty and working through those challenges to achieve success. This ability is essential to being a successful scientist, but replicating such challenges in a teaching setting can be difficult. The Genomics Education Partnership (GEP) is a consortium of faculty who engage their students in a genomics Course-Based Undergraduate Research Experience (CURE). Students participate in genome annotation, generating gene models using multiple lines of experimental evidence. Our observations suggested that the students' learning experience is continuous and recursive, frequently beginning with frustration but eventually leading to success as they come up with defendable gene models. In order to explore our "formative frustration" hypothesis, we gathered data from faculty via a survey, and from students via both a general survey and a set of student focus groups. Upon analyzing these data, we found that all three datasets mentioned frustration and struggle, as well as learning and better understanding of the scientific process. Bioinformatics projects are particularly well suited to the process of iteration and refinement because iterations can be performed quickly and are inexpensive in both time and money. Based on these findings, we suggest that a dynamic of "formative frustration" is an important aspect for a successful CURE., (©2020 Author(s). Published by the American Society for Microbiology.)

Hope is a trait that represents the capacity to identify strategies or pathways to achieve goals and the motivation or agency to effectively pursue those pathways. Hope has been demonstrated to be a robust source of resilience to anxiety and stress and there is limited evidence that, as has been suggested for decades, hope may function as a core process or transdiagnostic mechanism of change in psychotherapy. The current study examined the role of hope in predicting recovery in a clinical trial in which 223 individuals with 1 of 4 anxiety disorders were randomized to transdiagnostic cognitive behavior therapy (CBT), disorder-specific CBT, or a waitlist controlled condition. Effect size results indicated moderate to large intraindividual increases in hope, that changes in hope were consistent across the five CBT treatment protocols, that changes in hope were significantly greater in CBT relative to waitlist, and that changes in hope began early in treatment. Results of growth curve analyses indicated that CBT was a robust predictor of trajectories of change in hope compared to waitlist, and that changes in hope predicted changes in both self-reported and clinician-rated anxiety. Finally, a statistically significant indirect effect was found indicating that the effects of treatment on changes in anxiety were mediated by treatment effects on hope. Together, these results suggest that hope may be a promising transdiagnostic mechanism of change that is relevant across anxiety disorders and treatment protocols., (Copyright © 2019.

Background: The COVID-19 pandemic has had a profound impact on health and well-being worldwide and there is increasing recognition of the need to understand the psychological impact of COVID-19 experiences and stress in addition to the physical health consequences., Methods: The present study examined how experiences related to COVID-19 and associated stress impact, anxiety, depression, and functional impairment in a convenience sample of 565 American adults (57.9% male) recruited through MTURK., Results: COVID-19 experiences were consistently associated with higher odds of probable anxiety and depression diagnoses (ORs ≥ 3.0). COVID-19 associated stress also predicted large proportions of variance ( R 2  ≥ 30) in anxiety, depression, health anxiety, and functional impairment in latent variable analyses., Conclusions: These findings highlight that personal experiences related to the diagnosis of COVID-19, mortality in acquaintances, and COVID-19 associated stress is associated with a greatly elevated risk of emotional disorder symptomatology and that the COVID-19 pandemic may result in increased demand for mental health services., Competing Interests: Conflict of InterestMatthew W.

A novel Gram-stain-negative bacterium, designated as SCSIO 06110 T , was isolated from a deep-sea sediment of the West Pacific Ocean. Cells were 0.5-0.8 µm in width and 3.0-4.0 µm in length, spore-forming, rod-shaped with peritrichous flagella. Positive for catalase and urease, negative for oxidase and nitrate reduction. Growth occurred at 15-37 °C, pH 6-9 and 1-5 % (w/v) NaCl, with optimum growth at 28 °C, pH 7 and 3 % (w/v) NaCl. MK-7 was the only menaquinone. The strain possessed diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and two unidentified phospholipids. Iso-C 16 : 0 , iso-C 15 : 0 and iso-C 14 : 0 were the major fatty acids. The novel isolate clustered with genera in the family Paenibacillaceae , but formed a separated branch with the closest relative Chengkuizengella sediminis J15A17 T (91.1 % sequence similarity) when compared in a phylogenetic analysis of 16S rRNA gene sequences. The DNA G+C content of strain SCSIO 06110 T was 38.5 mol%. Based on the polyphasic data presented, a new genus, Longirhabdus gen. nov., is proposed in the family Paenibacillaceae with the type species Longirhabdus pacifica sp. nov. and the type strain SCSIO 06110 T (=DSM 105158 T =CGMCC 1.16550 T ).
