Insulin-degrading enzyme (IDE) is a human mononuclear Zn2+ -dependent metalloenzyme that is widely regarded as the primary peptidase responsible for insulin degradation. Despite its name, IDE is also critically involved in the hydrolysis of several other disparate peptide hormones, including glucagon, amylin, and the amyloid β-protein. As such, the study of IDE inhibition is highly relevant to deciphering the role of IDE in conditions such as type-2 diabetes mellitus and Alzheimer disease. There have been few reported IDE inhibitors, and of these, inhibitors that directly target the active-site Zn2+ ion have yet to be fully explored. In an effort to discover new, zinc-targeting inhibitors of IDE, a library of ∼350 metal-binding pharmacophores was screened against IDE, resulting in the identification of 1-hydroxypyridine-2-thione (1,2-HOPTO) as an effective Zn2+ -binding scaffold. Screening a focused library of HOPTO compounds identified 3-sulfonamide derivatives of 1,2-HOPTO as inhibitors of IDE (Ki values of ∼50 μM). Further structure-activity relationship studies yielded several thiophene-sulfonamide HOPTO derivatives with good, broad-spectrum activity against IDE that have the potential to be useful pharmacological tools for future studies of IDE.

To assess the effects of Retzius-sparing (RS) robotic-assisted laparoscopic prostatectomy (RALP) compared to standard RALP for the treatment of clinically localized prostate cancer.

We performed a systematic search of multiple databases and the grey literature with no restrictions on the language of publication or publication status, up until June 2020. We included randomized controlled trials (RCTs) comparing RS-RALP with standard RALP. We performed a meta-analysis using a random-effect model. The quality of evidence was assessed on an outcome basis according to the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach.

Our search identified six records of five unique RCTs, of which two were published studies, one was in press, and two were abstract proceedings. There were 571 randomized participants, of whom 502 completed the trials. The mean age of participants was 64.6years and the mean prostate-specific antigen level was 6.9ng/mL. Approximately 54.2% of participants had al and functional outcomes are lacking, and no preplanned subgroup analyses could be performed to explore the observed heterogeneity. Surgeons should discuss these trade-offs and the limitations of the evidence with their patients when considering this approach.

To investigate the frequency of fatigue and musculoskeletal symptoms and their correlation with laboratory data in patients with COVID-19.

This study included 80 patients hospitalised and treated for COVID-19 in the infectious diseases clinic between March 2020 and May 2020. Data analysis was performed retrospectively from the hospital medical charts. Venetoclax in vivo Demographic data, clinical symptoms, and laboratory findings were noted. Clinical symptoms and correlations with laboratory results were assessed. Besides, an analysis of patients with and without chronic disease was performed for clinical symptoms and laboratory findings.

The frequencies of myalgia and fatigue were 46.1% and 50%, respectively. In the laboratory data, there was a significant increase in creatinine kinase (CK) level and lymphocyte count in the patients with myalgia symptoms (P<.05). There were no other significant results in the laboratory data. Of the patients with chronic disease, it has been shown that hemoglobin levels were significantly decreased (P<.05), while D-dimer was markedly increased (P<.05).

The laboratory findings of COVID-19-related myalgia suggested that patients might have a risk of progressive muscle injury. Therefore, these patients should also be followed up in terms of the myopathic process.

This study aimed to investigate the protective effect of SCARF1 on acute rejection (AR), phagocytic clearance of Kupffer cells (KCs), M2 polarization and the exact mechanism underlying these processes.

AAV was transfected into the portal vein of rats, and AR and immune tolerance (IT) models of liver transplantation were established. Liver tissue and blood samples were collected. The level of SCARF1 was detected via WB and immunohistochemical staining. Pathological changes in liver tissue were detected using HE staining. Apoptotic cells were detected using TUNEL staining. KC polarization was assessed via immunohistochemical staining. Primary KCs were isolated and co-cultured with apoptotic T lymphocytes. Phagocytosis of apoptotic cells and polarization of KCs were both detected using immunofluorescence. Calcium concentration was determined using immunofluorescence and a fluorescence microplate reader. The levels of PI3K, p-AKT and P-STAT3 were assessed via WB and immunofluorescence.

Compared to the IT group, the level of SCARF1 was significantly decreased in the AR group. Overexpression of SCARF1 in KCs improved AR and liver function markers. Enhanced phagocytosis mediated by SCARF1 is beneficial for improving the apoptotic clearance of AR and promoting M2 polarization of KCs. SCARF1-mediated enhancement of phagocytosis promotes increased calcium concentration in KCs, thus further activating the PI3K-AKT-STAT3 signalling pathway.

SCARF1 promotes the M2 polarization of KCs by promoting phagocytosis through the calcium-dependent PI3K-AKT-STAT3 signalling pathway.

However, the mechanism of HDAC8 selective inhibition remains unclear. In this study, flexible docking and in silico mutation were used to explore the structural change of methionine (M274) during HDAC8 binding to inhibitors, along with the reason for this change. Meanwhile, steered and conventional molecular dynamics simulations were employed to explore the stability of the structural change. The findings suggest that M274 acts as a "switch" to control the exposure of the HDAC8-selective pocket. The structure of M274 changes from flipped-out to flipped-in only when L-shaped inhibitors bind to HDAC8. This structural change forms a groove that allows these inhibitors to enter the selective pocket. In other HDACs, a leucine residue replaces M274 in situ, and the same structural change is not observed. The findings reveal the mechanism of selective HDAC8 inhibition and provide guidance for the development of novel selective inhibitors.
