Bacterial Metabolism Pathways as well as the "Fermented Plant Foods-Human Health" Axis.
Non-small cell lung cancer (NSCLC) is a common lung cancer with high mortality worldwide. Cisplatin (DDP) resistance is a huge limitation for NSCLC therapy. FGD5 antisense RNA 1 (FGD5-AS1) was recognized as a significant cancer cell regulator. However, the molecular mechanism of FGD5-AS1 in cisplatin resistance of NSCLC cells is poorly understood. FGD5-AS1 and WEE1 expression were up-regulated in DDP-resistant tumors and cells compared with DDP-sensitive ones. Interestingly, down-regulation of FGD5-AS1 or WEE1 inhibited cell proliferation, migration, invasion, autophagy and stimulated cell apoptosis in NSCLC DDP-resistant cells. What's more, restoration of WEE1 abrogated FGD5-AS1 silencing-induced suppression on cell proliferation, migration, invasion, autophagy and promotion on cell apoptosis in NSCLC DDP-resistant cells. Next, we discovered that FGD5-AS1 was able to enhance WEE1 expression by interacting with miR-140-5p. Furthermore, FGD5-AS1 silencing restrained tumor growth of cisplatin-resistant mice. Overexpression of FGD5-AS1 accelerated cell proliferation, migration, invasion and autophagy by enhancing cisplatin resistance against NSCLC cells through miR-140-5p/WEE1 axis, presenting promising biomarkers for the diagnosis of DDP-resistant NSCLC patients.Background and aims Current colon capsule cleansing grading scales rely on subjective parameters and lack proper interobserver agreement. We should strive for higher intra- and interobserver agreement for the evaluation of colon capsules' cleansing quality. Validation of a new grading scale for the evaluation of colon capsule cleansing. Methods For the new grading scale (CC-CLEAR), the colon was divided in 3 segments right, transverse, and left colon. Each segment was scored according to an estimation of the percentage of visualized mucosa (0 0.01). Conclusion CC-CLEAR is a new practical and reliable grading scale for the evaluation of bowel preparation quality in colon capsule, with excellent inter- and intraobserver agreement.Background and aims As community-based ambulatory endoscopy centers across the nation are trying to reopen and safely resume outpatient endoscopic procedures after the unprecedented lockdown related to the COVID-19 pandemic, guidelines recommend pre-testing and screening for COVID-19 along with other mitigation measures for the safety of patients and staff. Selleck Vorinostat The impact of such changes in the workflow of ambulatory endoscopy centers on throughput and other performance indicators is largely unknown although a significant reduction in revenue stream is expected. Methods A discrete event simulation-based model was developed in the setting of a small to medium community-based single-specialty ambulatory endoscopy center to quantify the impact of COVID-19 related workflow changes on performance indicators and cost per case compared with the pre-COVID-19 baseline. Results In the simulation model, post-COVID-19 recommended workflow changes significantly impacted the operational and productivity metrics and, in turn, adversely affected the financial metrics. Overall, there was a significant decrease in staff utilization, and consequent increase in total facility time, waiting time for patients, and cost per case because of a bottleneck at the time of preprocedure COVID-19 screening and testing while practicing social distancing. Strategies to minimize this adverse impact on productivity were assessed. Conclusion Pretesting and screening for COVID-19 as recommended by current guidelines will significantly impact the productivity and revenue stream of ambulatory endoscopy centers. Urgent measures by the payors are needed to adjust the facility reimbursement of endoscopy centers to ensure successful reopening and ramping up outpatient endoscopy services in these facilities already hit hard by the pandemic.Membranous nephropathy results from subepithelial antigen-antibody complex deposition along the glomerular basement membrane. Although PLA2R, THSD7A, and NELL-1 account for a majority (about 80%) of the target antigens, the target antigen in the remaining cases is not known. Using laser microdissection of PLA2R-negative glomeruli of patients with membranous nephropathy followed by mass spectrometry we identified a unique protein, Semaphorin 3B, in three cases. Mass spectrometry failed to detect Semaphorin-3B in 23 PLA2R-associated cases of membranous nephropathy and 88 controls. Semaphorin 3B in all three cases was localized to granular deposits along the glomerular basement membrane by immunohistochemistry. Next, an additional eight cases of Semaphorin 3B-associated membranous nephropathy were identified in three validation cohorts by immunofluorescence microscopy. In four of 11 cases, kidney biopsy also showed tubular basement membrane deposits of IgG on frozen sections. Confocal microscopy showed that both IgG and Semaphorin 3B co-localized to the glomerular basement membrane. Western blot analysis of five available sera showed reactivity to reduced Semaphorin 3B in four of four patients with active disease and no reactivity in one patient in clinical remission; there was also no reactivity in control sera. Eight of the 11 cases of Semaphorin 3B-associated membranous nephropathy were pediatric cases. Furthermore, in five cases, the disease started at or below the age of two. Thus, Semaphorin 3B-associated membranous nephropathy appears to be a distinct type of disease; more likely to be present in pediatric patients.In autosomal dominant polycystic kidney disease (ADPKD), there are only scarce data on the effect of salt and protein intake on disease progression. Here we studied association of these dietary factors with the rate of disease progression in ADPKD, and what the mediating factors are by analyzing an observational cohort of 589 patients with ADPKD. Salt and protein intake were estimated from 24-hour urine samples and the plasma copeptin concentration measured as a surrogate for vasopressin. The association of dietary intake with annual change in the estimated glomerular filtration rate (eGFR) and height adjusted total kidney volume (htTKV) growth was analyzed with mixed models. In case of significant associations, mediation analyses were performed to elucidate potential mechanisms. These patients (59% female) had a mean baseline age of 47, eGFR 64 mL/min/1.73m2 and the median htTKV was 880 mL. The mean estimated salt intake was 9.1 g/day and protein intake 84 g/day. During a median follow-up of 4.0 years, eGFR was assessed a median of six times and 24-hour urine was collected a median of five times.
