Our calculations also indicate that the stabilization through hydroxyl termination of both chain- and graphene-like ZnO clusters not only could be a promising driving force to obtain larger atomic-scale 1D and 2D nanostructures but also envisage interesting properties, particularly as electronic acceptor materials for energy applications.Benzimidazole is a heterocyclic ring system that has been widely studied in the pharmaceutical field. For the past decade, numerous benzimidazole derivatives have been synthesized and evaluated for their wide range of pharmacological activities, which are beneficial for drug development. This article presents the biological effects of benzimidazole derivatives in each invention from 2015 to 2020. Two patent databases, Google Patents and Lens, were used to locate relevant granted patent applications. Specifically, this review delineates the role of patented benzimidazoles from a disease-centric perspective and examines the mechanisms of action of these compounds in related diseases. Most of the benzimidazoles have shown good activities against various target proteins. Whilst several of them have progressed into clinical trials, most patents presented novel therapeutic approaches for respective target diseases. Hence, their potential in being developed into clinical drugs are also discussed.
Infrapyloric lymph node dissection in right colon cancer patients remains controversial. We aimed to investigate the pattern of infrapyloric lymph node metastasis in right colon cancer patients.

Clinical and pathological data of 140 colon cancer patients who underwent radical right hemicolectomy and infrapyloric lymph node dissection were retrospectively examined. Patient characteristics, intraoperative conditions, postoperative recovery information, postoperative pathological findings, and follow-up data were examined.

About 19, 44, 73, and 4 patients had tumors located in the cecum, ascending colon, hepatic flexure, and right side of the transverse colon, respectively. The median number of harvested lymph nodes and that of positive lymph nodes were 24 (16-30) and 1 (0-7.75), respectively. The lymph node metastasis rate was 41.43% (58/140). The corresponding values for infrapyloric lymph nodes were 3 (1-4), 0(0-0), and 0.71% (1/140), respectively. The median follow-up duration was 19 (0-65) months in 131 (93.6%) patients. The 5-year overall and disease-free survival rates were 86.3% and 73.5%, respectively.

Given the low rate of infrapyloric lymph node metastasis in right colon cancer, lymph node dissection is recommended in patients with locally advanced colon cancer at the hepatic flexure and those with suspected infrapyloric lymph node metastasis.

Here, we studied the inhibitory effects of aqueous extracts of fermented barley with Lactobacillus plantarum dy-1 (LFBE) and beta-glucan (BGL) on the obesity induced by HFD. Both LFBE and BGL significantly decreased body weight, suppressed visceral lipid accumulation, improved blood lipid profile, and glucose tolerance in HFD rats. selleck inhibitor BGL showed no thermogenic capacity, while LFBE enhanced the expression of Uncoupling Protein 1 (UCP1), and brown-specific mRNA (PRDM16, PGC1-α, and CIDEA) levels in brown adipose tissue (BAT) and white adipose tissues (WAT) of HFD rats. In addition, LFBE increased the expression of key genes involved in mitochondria biosynthesis and the mitochondrial respiration function. Further, we demonstrated that proteins extracted from LFBE (LFBE-P) were responsible for triggering brown markers to some extent. In conclusion, LFBE alleviates HFD-induced obesity by activating thermogenic fat bioenergetics and mitochondria biosynthesis. PRACTICAL APPLICATIONS Barley is one of the most productive crops with pretty low utilization. Our group committed to exploring the application and nutritional value of barley. This work aimed to explore improvements in nutritional function of barley after fermentation by Lactobacillus plantarum dy-1. Our study found that oral administration of LFBE help turning white adipose tissue into a thermogenesis state and activate heat generation function of brown adipose tissue. Its characteristics mentioned above significantly inhibited the body weight and blood lipid of high-fat diet rats. Further, we evidenced that LFBE-P were responsible for triggering brown markers in 3T3-L1 cells. We believe our research plays a great part to relieving high-fat diet-induced obesity and type 2 diabetes with functional diet supplementation.Low-dose methotrexate is the first-line therapy for juvenile idiopathic arthritis. In vivo, methotrexate is converted into a series of methotrexate polyglutamates whose intracellular levels contribute significantly to its efficacy and toxicity. In this study, a novel high-performance liquid chromatography-tandem mass spectrometry method was developed and validated to simultaneously determine erythrocyte methotrexate polyglutamates using stable isotope-labeled internal standards. Erythrocyte samples were precipitated by perchloric acid and then determined on an XBridge BEH C18 column with an XP vanguard precolumn in 12 min. The mobile phase consisted of 10 nM ammonium acetate (pH 10) and methanol under gradient elution. The detection was carried out in multiple reaction monitoring mode via an electrospray ionization source in positive ionization mode. The calibration curve for each metabolite was linear from 2.0 to 500.0 nmol/L (r2 > 0.99). The intraday and interday accuracies were between 93.0 and 107.0%, and the corresponding precisions were between 0.8 and 5.2%. The relative recovery ranged from 82.7 to 105.1%, and the relative matrix effect varied from 96.5 to 104.4%. The erythrocyte metabolites were stable for 30 days at -80°C. This simple and accurate method is applicable to routine monitoring of the concentration of erythrocyte methotrexate polyglutamates in patients to achieve individualized treatment.
Bleeding after endoscopic submucosal dissection (ESD) is a main adverse event. To date, although there have been several studies about risk factors for post-ESD bleeding, there has been few predictive model for post-ESD bleeding with large volume cases. We aimed to design a prediction model for post-ESD bleeding using a classification tree model.

We analyzed a prospectively established cohort of patients with gastric neoplasms treated with ESD from 2007 to 2016. Baseline characteristics were collected for a total of 5080 patients, and the bleeding risk was estimated using variable statistical methods such as logistic regression, AdaBoost, and random forest. To investigate how bleeding was affected by independent predictors, the classification and regression tree (CART) method was used. The prediction tree developed for the cohort was internally validated.

Post-ESD bleeding occurred in 262 of 5080 patients (5.1%). In multivariate logistic regression, ongoing antithrombotic use during the procedure, cancer pathology, and piecemeal resection were significant risk factors for post-ESD bleeding. In the CART model, the decisive variables were ongoing antithrombotic agent use, resected specimen size ≥49mm, and patient age <62years. The CART model accuracy was 94.9%, and the cross-validation accuracy was 94.8%.

We developed a simple and easy-to-apply predictive tree model based on three risk factors that could help endoscopists identify patients at a high risk of bleeding. This model will enable clinicians to establish precise management strategies for patients at a high risk of bleeding and to prevent post-ESD bleeding.

Within this emerging class of wearables, microneedle-based transdermal sensors are in a prime position to play a key role in synergizing the significant advantages of dermal interstitial fluid (ISF) as a rich source of clinical indicators and painless skin pricking to allow the collection of real-time diagnostic information. While initial efforts of microneedle sensing focused on ISF extraction coupled with either on-chip analysis or off-chip instrumentation, the latest trend has been oriented toward assembling electrochemical biosensors on the tip of microneedles to allow direct continuous chemical measurements. In this context, significant advances have recently been made in exploiting microneedle-based devices for real-time monitoring of various metabolites, electrolytes, and therapeutics and toward the simultaneous multiplexed detection of key chemical markers; yet, there are several grand challenges that still exist. In this review, we outline current progress, recent trends, and new capabilities of microneedle-empowered sensors, along with the current unmet challenges and a future roadmap toward transforming the latest innovations in the field to commercial products.The illicit drug overdose crisis in North America continues to devastate communities with fentanyl detected in the majority of illicit drug overdose deaths. The COVID-19 pandemic has heightened concerns of even greater unpredictability in the drug supplies and unprecedented rates of overdoses. Portable drug-checking technologies are increasingly being integrated within overdose prevention strategies. These emerging responses are raising new questions about which technologies to pursue and what service models can respond to the current risks and contexts. In what has been referred to as the epicenter of the overdose crisis in Canada, a multi-technology platform for drug checking is being piloted in community settings using a suite of chemical analytical methods to provide real-time harm reduction. These include infrared absorption, Raman scattering, gas chromatography with mass spectrometry, and antibody-based test strips. In this Perspective, we illustrate some advantages and challenges of using multiple techniques for the analysis of the same sample, and provide an example of a data analysis and visualization platform that can unify the presentation of the results and enable deeper analysis of the results. We also highlight the implementation of a various service models that co-exist in a research setting, with particular emphasis on the way that drug checking technicians and harm reduction workers interact with service users. Finally, we provide a description of the challenges associated with data interpretation and the communication of results to a diverse audience.
