Molten salt derived crystalline graphitic carbon nitride to enable selective photo-oxidation of benzyl alcohol

xlomafota.13 shared this article with you from Inoreader Molten salt derived crystalline graphitic carbon nitride to enable selective photo-oxidation of benzyl alcohol Via Latest Results for Journal of Nanoparticle Research Abstract Graphitic carbon nitride with low cost was a fascinating metal-free photocatalyst for alcohol oxidation. However, pristine graphitic carbon nitride typically revealed fast charge recombination owing to incomplete polymerization. Therefore, increasing the degree of polymerization can be one of the effective ways to enhance its photocatalytic activity. Crystalline graphitic carbon nitride was prepared with the aim of modifying charge separation efficiency and increasing crystallinity for advancing catalytic performance by salt melting method. PTI owned a more positive valence band value (2.48 eV) than that of bulk g-C3N4, promising to enhance thermodynamic driving force toward photocatalytic oxidation reactions. In addition, PTI revealed effective adsorption ability for substrates by density functional theory (DFT) calculations. The optimal benzyl alcohol conversion efficiency was 59.3% with selectivity of > 99%. Meanwhile, the recycling experimental results demonstrated that PTI phtocatalyst owed an outstanding reusability and durability. The radical scavenging experiments and EPR analysis demonstrated that both •O2- and holes were the main reactive species in photocatalytic alcohol oxidation. This work might offer an avenue to conveniently prepare and bring a new opportunity to exploit photocatalysts with excellent photocatalytic alcohol oxidation performance. View on the web Inoreader.

Local application reduces number of needed EPC for beneficial effects on wound healing compared to systemic treatment in mice

xlomafota.13 shared this article with you from Inoreader Local application reduces number of needed EPC for beneficial effects on wound healing compared to systemic treatment in mice Via Latest Results for European Journal of Trauma and Emergency Surgery Abstract Introduction Stem cell transplantation is one of the most promising strategies to improve healing in chronic wounds as systemic administration of endothelial progenitor cells (EPC) enhances healing by promoting neovascularization and homing though a high amount of cells is needed. In the following study, we analysed whether local application can reduce the number of EPC needed achieving the same beneficial effect on wound healing. Material and Methods Wound healing after local or systemic treatment with EPC was monitored in vivo by creating standardized wounds on the dorsum of hairless mice measuring wound closure every second day. Systemic group received 2 × 106 EPC i.v. and locally treated group 2 × 105 EPC, locally injected. As control PBS injection was performed the same way. Expression of CD31, VEGF, CD90 and, SDF-1α was analysed immunohistochemically for evaluation of neovascularisation and amelioration of homing. Results Local (7.1 ± 0.45 SD) as well as systemic (6.1 ± 0.23 SD) EPC transplantation led to a significant acceleration of wound closure compared to controls (PBS local: 9.7 ± 0.5 SD, PBS systemic 10.9 ± 0.38 SD). Systemic application enhanced CD31 expression on day 6 after wounding and local EPC on 6 and 9 in comparison to control. VEGF expression was not significantly affected. Systemic and local EPC treatment resulted in a significantly enhanced SDF-1α and CD90 expression on all days investigated. Conclusion Local as well as systemic EPC treatment enhances wound healing. Moreover, beneficial effects are obtained with a tenfold decrease number of EPC when applied locally. Thus, local EPC treatment might be more convenient way to enhance wound healing as number of progenitor cells is limited. View on the web Inoreader. Take back control of your news feed.

Comparison of Liver Recovery After Sleeve Gastrectomy and Roux-en-Y-Gastric Bypass

xlomafota.13 shared this article with you from Inoreader Comparison of Liver Recovery After Sleeve Gastrectomy and Roux-en-Y-Gastric Bypass Via Latest Results for Obesity Surgery Abstract Background Nonalcoholic fatty liver disease (NAFLD) is a common condition in patients with obesity. Bariatric surgery has often been proposed as a viable treatment option, but the ideal surgical procedure remains unclear. Inconsistently, reports on postoperative deterioration of liver function put further doubt on which technique to apply. Aim of this study was to assess the impact of Roux-en-Y-gastric bypass (RYGB) and sleeve gastrectomy (SG) on the postoperative recovery of liver function. Methods A total of 175 patients with obesity that underwent bariatric surgery in our institution were included in this prospective cohort study. BMI, laboratory values, and liver function capacity (using LiMAx) were assessed preoperatively and at 6 and 12 months postoperatively. Generalized linear model (GLM) was performed to determine variables influencing liver function capacity after the operation. Results Prior to operations, 64% of patients presented with a diminished liver function capacity, as measured by LiMAx test. Liver function capacity significantly recovered after 12 months in the SG group (300 μg/kg/h preop vs. 367 μg/kg/h postop) but not in the RYGB group (306 μg/kg/h preop vs. 349 μg/kg/h). Preoperative factors impeding liver function recovery included type 2 diabetes mellitus (T2DM), weight, male sex, AST/thrombocyte ratio (APRI), and gamma-glutamyltransferase (GGT). Conclusion Bariatric surgery, especially sleeve gastrectomy, leads to an improvement of liver function. However, in some patients with T2DM, higher preoperative weight and male sex postoperative deterioration of liver function capacity may occur. Graphical abstract View on the web Inoreader.

Establishment and characterization of 38 novel patient-derived primary cancer cell lines using multi-region sampling revealing intra-tumor heterogeneity of gallbladder carcinoma

xlomafota.13 shared this article with you from Inoreader Establishment and characterization of 38 novel patient-derived primary cancer cell lines using multi-region sampling revealing intra-tumor heterogeneity of gallbladder carcinoma Via Latest Results for Human Cell Abstract Gallbladder carcinoma (GBC) is a lethal biliary tract malignant neoplasm. Patient-derived primary cancer cell lines (PDPCs) are appropriate models to explore biological characteristics and potential therapeutics; however, there is a lack of PDPCs in GBC. In this study, we aimed to establish and characterize the GBC PDPCs, and further investigated the intra-tumor heterogeneity (ITH). Multi-region sampling (3–9 regions) of the operable tumor tissue samples was used to establish PDPCs. Short tandem repeat genotyping for cell authentication and karyotyping was performed, followed by whole-exome sequencing and RNA sequencing to assess the ITH at the genetic and transcriptional levels, respectively. Thirty-eight PDPCs were successfully established from seven GBC patients and characterized. ITH was observed with a median of 38.3% mutations being heterogeneous (range, 26.6–59.4%) across all patients. Similar with other tumor types, TP53 mutations were always truncal. In addition, there were three genes, KMT2C, CDKN2A, and ARID1A, with truncal mutations in at least two patients. A median of 370 differentially expressed genes (DEGs) was identified per patient. Distinct expression patterns were observed between major histocompatibility complex (MHC) class I and II genes. We found the expression of MHC class II genes in the PDPC samples was closely regulated by CIITA, while that of MHC class I genes were not correlated with CIITA expression. The PDPCs established from GBC patients can serve as novel in vitro models to identify the ITH, which may pave a crucial molecular foundation for enhanced understanding of tumorigenesis and progression.

Geriatric assessment and medical preoperative screening (GrAMPS) program for older hernia patients

xlomafota.13 shared this article with you from Inoreader Geriatric assessment and medical preoperative screening (GrAMPS) program for older hernia patients Via Latest Results for Hernia Abstract Purpose The incidence of older adults undergoing inguinal and ventral hernia repairs is increasing. Older adults are disproportionately affected by age-related risk factors, which are often under-recognized and may adversely affect surgical outcomes. These age-related risk factors often termed "geriatric syndromes," include multimorbidity, frailty, cognitive impairment, depression, obesity, functional impairment, polypharmacy, and poor subjective health. The aim of this study was to identify the prevalence of age-related risk factors in older patients undergoing elective hernia repair. Methods Patients aged 60 years or older with a planned elective surgical repair of a ventral or inguinal hernia were prospectively enrolled in a clinic. Subjects completed several validated screening tools for geriatric syndromes. Results Seventy patients completed preoperative assessments (mean age: 68.5 years). In total, 24 (34.3%) screened positive for previously unrecognized objective cognitive impairment (Mini-Cog) and 33 (47.1%) for a subjective memory concern. Sixty patients (85.7%) met criteria for polypharmacy. Additionally, 48 (68.6%) screened positive for either pre-frailty (37, 52.9%) or frailty (11, 15.7%), and 66 (94.3%) had multimorbidity. Twenty-five (35.7%) patients self-rated their health as "poor" or "fair," and 18 (25.7%) patients endorsed some functional impairment. Conclusions There is a high prevalence of age-related risk factors in older patients undergoing elective hernia repair. Further, these factors are often unrecognized and underappreciated despite their potential to significantly impact informed consent and shared decision making. Additional study is required to define the impact of these age-related risk factors on surgical outcomes, which will inform preoperative risk assessment and optimization through modifiable risk reduction.

A Stakeholder-Engaged Process for Adapting an Evidence-Based Intervention for Posttraumatic Stress Disorder for Peer Delivery

xlomafota.13 shared this article with you from Inoreader A Stakeholder-Engaged Process for Adapting an Evidence-Based Intervention for Posttraumatic Stress Disorder for Peer Delivery Via Latest Results for Administration and Policy in Mental Health and Mental Health Services Research Abstract Purpose Peer providers represent a growing sector of the U.S. workforce, yet guidance is needed on best practices for adapting behavioral health interventions for peer delivery. Methods We utilized the Framework for Reporting Adaptations and Modifications to Evidence-based interventions (FRAME; Wiltsey Stirman et al. 2013, 2019) to describe how we systematically adapted Skills Training in Affective and Interpersonal Regulation (STAIR) for posttraumatic stress disorder (PTSD) for peer delivery. Our process was iterative and relied on engagement of multiple stakeholders, including a work group of organizational leaders (N = 5), peer interventionists (N = 4), intervention experts (N = 2), and trial participants (N = 18). The FRAME was used to guide rapid coding across multiple data sources, including researcher field notes, meeting minutes, and intervention manual documents, and content analysis of semi-structured interviews with peer interventionists and trial participants. Results Phase 1 (pre-trial) focused on modifications for fit with the local context and peer model. Key modifications focused on improving intervention design and packaging, removing clinical and stigmatizing language, and addressing peer interventionist training gaps. We used a hybrid approach to delivery, whereby we integrated peer model principles (self-disclosure, mutuality) into a directive approach. Phase 2 (trial) included reactive fidelity-consistent adaptations, such as additional educational resources. Phase 3 (post-trial) focused on adaptations to support roll-out of the intervention at the peer organization (e.g., group format). Conclusion Our stakeholder-engaged process may serve as a helpful exemplar to others tailoring interventions for peer delivery. Future research is needed to understand the role of stakeholder engagement and adaptation in implementation success. View on the web Inoreader. Take back control of your news feed.

MiR-193a-3p Promotes Fracture Healing via Targeting PTEN Gene

xlomafota.13 shared this article with you from Inoreader MiR-193a-3p Promotes Fracture Healing via Targeting PTEN Gene Via Latest Results for Molecular Biotechnology Abstract The aim of this study was to investigate the role and potential mechanism of miR-193a-3p in fracture healing. The 70 fragility fracture patients and 45 healthy controls were enrolled in this study. Quantitative real-time PCR (qRT-PCR) was used for the measurement of the expression levels of miR-193a-3p and PTEN. MTT assay and flow cytometry were used to detect cell viability and apoptosis in the mouse osteoblastic cell line MC3T3-E1. Luciferase reporter assay was performed to confirm the correlation of miR-193a-3p with PTEN. The serum expression level of miR-193a-3p showed no significant change in fracture patients 7 days after fixation treatment, but over time, there was a significant decrease in the expression at 14 days and 21 days after treatment (P < 0.01). Overexpression of miR-193a-3p significantly enhanced cell viability and inhibited cell apoptosis in MC3T3-E1 cells (P < 0.001). Serum P TEN level in fracture patients was increased gradually during the fracture healing process (P < 0.01). PTEN was demonstrated to be a target gene of miR-9-5p and reversed the effect of miR-193a-3p on cell viability and apoptosis (P < 0.001). miR-193a-3p promoted fracture healing via regulating PTEN and may serve as a novel potential target for enhancing bone repair of fragility fracture.

Right-sided Zenker’s diverticulum resected using intraoperative neuromonitoring

xlomafota.13 shared this article with you from Inoreader Right-sided Zenker's diverticulum resected using intraoperative neuromonitoring Via Latest Results for Clinical Journal of Gastroenterology Abstract Right-sided Zenker's diverticulum is a rare pharyngoesophageal diverticulum. The risk of intraoperative injury of the recurrent laryngeal nerve is high during transcervical diverticulectomy because this nerve presents many variations of extralaryngeal bifurcation before entry into the larynx. We present a case of right-sided Zenker's diverticulum that was safely resected with the use of intraoperative neuromonitoring to prevent right recurrent laryngeal nerve injury. A 55-year-old man complaining of chronic cough and regurgitation of ingested food was diagnosed as having right-sided Zenker's diverticulum and underwent open transcervical diverticulectomy and cricopharyngeal myotomy. The location of the right recurrent laryngeal nerve was accurately determined during dissection by intermittent stimulation using a monopolar stimulation probe of an intraoperative neuromonitoring system to avoid injury. The postoperative course was uneventful, and postoperative evaluation showed no vocal cord paralysis. Intraoperative neuromonitoring may be beneficial during transcervical diverticulectomy for right-sided Zenker's diverticulum nearby the right recurrent laryngeal nerve, which can present with many variations of extralaryngeal bifurcation.

No evidence for an effect of working from home on neck pain and neck disability among Swiss office workers: Short-term impact of COVID-19

xlomafota.13 shared this article with you from Inoreader No evidence for an effect of working from home on neck pain and neck disability among Swiss office workers: Short-term impact of COVID-19 Via Latest Results for European Spine Journal Abstract Purpose The aim of this study was to investigate the effect of working from home on neck pain (NP) among office workers during the COVID-19 pandemic. Methods Participants from two Swiss organisations, aged 18–65 years and working from home during the lockdown (n = 69) were included. Baseline data collected in January 2020 before the lockdown (office work) were compared with follow-up data in April 2020 during lockdown (working from home). The primary outcome of NP was assessed with a measure of intensity and disability. Secondary outcomes were quality of workstation ergonomics, number of work breaks, and time spent working at the computer. Two linear mixed effects models were fitted to the data to estimate the change in NP. Results No clinically relevant change in the average NP intensity and neck disability was found between measurement time points. Each working hour at the computer increased NP intensity by 0.36 points (95% CI: 0.09 to 0.62) indicating strong evidence. No such effect was found for neck disability. Each work break taken reduced neck disability by 2.30 points (95% CI:  − 4.18 to  − 0.42, evidence). No such effect was found for NP intensity. There is very strong evidence that workstation ergonomics was poorer at home. Conclusion The number of work breaks and hours spent at the computer seem to have a greater effect on NP than the place of work (office, at home), measurement time point (before COVID-19, during lockdown) or the workstation ergonomics. Further research should investigate the effect of social and psychological factors. Trial registration ClinicalTrials.gov, NCT04169646.

Catheter Ablation of Atrial Fibrillation in Heart Failure: from Evidences to Guidelines

xlomafota.13 shared this article with you from Inoreader Catheter Ablation of Atrial Fibrillation in Heart Failure: from Evidences to Guidelines Via Latest Results for Current Heart Failure Reports Abstract Purpose of Review Catheter ablation of atrial fibrillation in heart failure seems to be the way to improve the quality of life, life expectance, and prognosis. In this review, we outline the growing role of this therapy and which patients can benefit from it. Recent Findings While previous studies comparing rate control and rhythm control had not demonstrated the superiority of rhythm control in the prognosis of patients with atrial fibrillation and heart failure, recent findings seem to demonstrate that catheter ablation of atrial fibrillation reduces mortality and hospitalization for heart failure and improves the quality of life, when compared to medical therapy alone. Summary An early rhythm-control strategy in atrial fibrillation may reduce cardiovascular death, stroke, hospitalization for HF, or acute coronary syndrome. Catheter ablation in heart failure is an effective and safe solution to obtain a rhythm control and, therefore, to improve outcomes. A better selection of the patients could help to avoid futile procedures and to identify patients requiring a closer follow-up, to redo procedures, or the addition of antiarrhythmic drugs.
