Few microbes can grow under laboratory conditions, highlighting the fact that the majority of microbes in environment are still uncultured and untapped resources. This study used alternative cultivation methods, diffusion chambers (DC), dilution-to-extinction culture (DTE) and modified agar preparation step (PS media) to cultivate previously uncultured marine bacterial species. These methods were applied to samples from a coastal intertidal zone, and the results were compared with those from standard direct plating (SDP) cultivation. Among the strains isolated with DC, DTE and PS media methods, 28%, 48% and 33% were novel species, respectively, while the SDP method resulted in the isolation of only 9% of novel species. Most isolates were unique to the method used for their cultivation. This implies that each method is selective in its own way, which is different from SDP, thus able to access species that are difficult to obtain using conventional approaches. Comparing the diversity showed that 75 genera were recovered by the alternative methods, 2.7 times higher than that of the SDP cultivation, which constituted 45% of total diversity from culture-independent sequencing. We conclude that combining alternative cultivation methods represents a highly promising key for accessing 'microbial dark matter'.To investigate the effects of RNA-binding proteins cold-inducible RNA binding protein (CIRP) and human antigen R (HuR) on expression of Claudin1 and mucosal barrier function in ulcerative colitis (UC). The clinical specimens of UC patients and healthy volunteers were collected. In the clinical experiments, the expressions of CIRP, Claudin1, and HuR, along with their correlations in tissues of UC patients were analyzed by qRT-PCR, Western blot and Pearson correlation coefficient, respectively. The chi-square test was utilized to assess the relevance between CIRP/HuR/Claudin1 level and clinicopathological characteristics of UC patients. The in vitro and in vivo models of UC were established by lipopolysaccharide treatment or dextran sulfate sodium injection. For cell experiments, after loss- and gain-of-function, the roles of CIRP or HuR in the apoptosis and proliferation of enterocytes were examined by flow cytometry and CCK-8 assay. The intestinal epithelial barrier function was inspected after determination enhanced by HuR. HuR and CIRP can competitively bind to Claudin1. HuR upregulation or CIRP downregulation promoted proliferation, suppressed apoptosis and ameliorated the damage of the barrier function in enterocytes. The in vivo experiments verified that the ameliorated damage of the intestinal mucosal barrier function in UC mice occurred with HuR overexpression or CIRP knockdown. CIRP and HuR confer pivotal effect on the intestinal mucosal barrier function of UC through competitively binding to Claudin1 mRNA.

To compare complications of dogs treated with mandibular and sublingual sialoadenectomy for sialocele using a lateral (LAT) or ventral paramedian (VPM) approach.

Retrospective multicenter study.

Dogs (140) with mandibular and sublingual sialocele.

Medical records of dogs that underwent mandibular and sublingual sialoadenectomy through a LAT or VPM approach from 2004 to 2020 were reviewed. Clinical and histopathological findings were analyzed to compare the groups.

Seventy dogs were included in each group. The most represented breed was crossbreed (26%), and males (99/140 [71%], intact/neutered) were overrepresented. Dogs in the VPM approach group were more likely to undergo digastricus tunnelization and placement of a drain or a bandage. Dogs in the LAT approach group were heavier and more likely to undergo excision of an inflammatory pseudocapsule. bpV in vivo No difference was detected in complication rates between groups (LAT [20%], VPM [31%], P = .116). Recurrences were more likely after LAT approach (5/70 vs 0/70, respectively; P = .029), whereas wound-related complications were more likely after VPM approach (20/70 vs 9/70, respectively; P = .018). Prolonged duration of surgery was associated with an increased risk of recurrence, and none of the other variables affected the complication rate.

Ventral paramedian approach for mandibular and sublingual sialoadenectomy was associated with a lower risk of recurrence but a higher risk of wound-related complications compared with LAT approach.

Ventral paramedian approach for mandibular and sublingual sialoadenectomy may be preferred to reduce recurrence in dogs with sialoceles, but wound-related complications are common.

There are several ways to determine psychological resilience. However, the correlation between each measurement is not clear. We explored associations of baseline relative "resilience" and risk with later self-reported trait resilience and other biological/mental health indices.

We utilized baseline and follow-up survey data from 500 participants aged 30-64 in the community cohort. Baseline "relative" resilience was defined by (a) negative life events (NLEs) in the six months before baseline and (b) depressive symptoms at baseline, yielding four groups of individuals i) "Unexposed and well," "Vulnerable (depression)," "Reactive (depression)," and "Resilient." "Trait" resilience at follow-up was self-reported using the Connor-Davidson Resilience Scale (CD-RISC). Associations between relative resilience at baseline, CD-RISC, and heart rate variability (HRV) indices at follow-up were assessed with generalized linear regression models after adjustments. Associations between baseline resilience and subsequent ern of CD-RISC was different by sex.

Statins are widely used to lower lipids and reduce cardiovascular events. In vitro studies and small studies in patients with hyperlipidemias show statins inhibit tissue factor (TF) and blood coagulation mechanisms. We assessed the effects of simvastatin on TF and coagulation biomarkers in patients entered in STATCOPE, a multicenter, randomized, placebo-controlled trial of simvastatin (40mg daily) versus placebo on exacerbation rates in patients with chronic obstructive pulmonary disease (COPD).

In 227 patients (114 simvastatin, 113 placebo; mean [± standard error of the mean] age 62±0.53years, 44.5% women) we measured (baseline, and 6 and 12months) whole blood membrane TF-procoagulant activity (TF-PCA) and plasma factors VIIa, VII, VIII, fibrinogen, TF antigen, tissue factor pathway inhibitor (TFPI), thrombin-antithrombin complexes (TAT), and D-dimer. We excluded patients with diabetes, cardiovascular disease, and those taking or requiring a statin.

In the statin group, there was a small increase in TF-PCA (from 25.
