Denfivontinib activates effector T-cells through NLRP3-inflammasome, yielding potent anticancer effects by combination with pembrolizumab.

Various combination therapies have been investigated to overcome the limitations of using immune checkpoint inhibitors. However, determining the optimal combination therapy remains challenging. To overcome the therapeutical limitation, we conducted a translational research to elucidate the mechanisms by which AXL inhibition enhances the anti-tumor effects when combined with anti-PD-1 antibody therapy.

Acidic polysaccharide from the edible insect Protaetia brevitarsis seulensis activates antiviral immunity to suppress norovirus infection.

Edible insects are gaining attention as potential nutraceutical sources with immunomodulatory properties. This study reports purification and structural characterization of polysaccharides from Protaetia brevitarsis seulensis larvae (PBSL) with antiviral activity against murine norovirus. Four polysaccharide fractions purified from PBSL water extracts exhibited varying molecular weights (458.

Impact of Chronic Hepatitis C Virus on Acute Kidney Injury After Living Donor Liver Transplantation.

Background: Acute kidney injury (AKI) is one of the most common complications after liver transplantation (LT) and can significantly impact outcomes. The presence of hepatitis C virus (HCV) infection increases the risk of AKI development. However, the impact of HCV on AKI after LT has not been evaluated.

Scalable production of siRNA-encapsulated extracellular vesicles for the inhibition of KRAS-mutant cancer using acoustic shock waves.

Extracellular vesicles (EVs) have emerged as a potential delivery vehicle for nucleic-acid-based therapeutics, but challenges related to their large-scale production and cargo-loading efficiency have limited their therapeutic potential. To address these issues, we developed a novel "shock wave extracellular vesicles engineering technology" (SWEET) as a non-genetic, scalable manufacturing strategy that uses shock waves (SWs) to encapsulate siRNAs in EVs. Here, we describe the use of the SWEET platform to load large quantities of KRAS-targeting siRNA into small bovine-milk-derived EVs (sBMEVs), with high efficiency.

Benefits of liver transplant in critically ill patients with acute-on-chronic liver failure: Implementation of an urgent living-donor program.

We evaluated the liver transplantation (LT) criteria in acute-on-chronic liver failure (ACLF), incorporating an urgent living-donor LT (LDLT) program. Critically ill patients with a Chronic Liver Failure Consortium (CLIF-C) ACLF score (CLIF-C_ACLF_score) ≥65, previously considered unsuitable for LT, were included to explore the excess mortality threshold of the CLIF-C_ACLF_score (CLIF-C_ACLF_score_threshold). We followed 854 consecutive patients with ACLF (276 ACLF grade 2 and 215 ACLF grade 3) over 10 years among 4432 LT recipients between 2008 and 2019.

Association Between QRS Characteristics in Pulseless Electrical Activity and Survival Outcome in Cardiac Arrest Patients: A Systematic Review and Meta-Analysis.

Objective: Recent studies have shown inconsistent results regarding the association between QRS characteristics and survival outcomes in patients with cardiac arrest and pulseless electrical activity (PEA) rhythms. This meta-analysis aimed to identify the usefulness of QRS width and frequency as prognostic tools for outcomes in patients with cardiac arrest and PEA rhythm.

Methods: Extensive searches were conducted using Medline, Embase, and the Cochrane Library to find articles published from database inception to 4 June 2023.

A wirelessly programmable, skin-integrated thermo-haptic stimulator system for virtual reality.

Sensations of heat and touch produced by receptors in the skin are of essential importance for perceptions of the physical environment, with a particularly powerful role in interpersonal interactions. Advances in technologies for replicating these sensations in a programmable manner have the potential not only to enhance virtual/augmented reality environments but they also hold promise in medical applications for individuals with amputations or impaired sensory function. Engineering challenges are in achieving interfaces with precise spatial resolution, power-efficient operation, wide dynamic range, and fast temporal responses in both thermal and in physical modulation, with forms that can extend over large regions of the body.

Effect of dexmedetomidine on the incidence of postoperative acute kidney injury in living donor liver transplantation recipients: a randomized controlled trial.

Background: Acute kidney injury (AKI) is one of the most common complications after living-donor liver transplantation (LDLT) that has great impact on recipient and graft outcomes. Dexmedetomidine is reported to decrease the incidence of AKI. In the current study, the authors investigated whether intraoperative dexmedetomidine infusion would reduce the AKI following LDLT.

Analysis of tumor mutational burden and mutational landscape comparing whole-exome sequencing and comprehensive genomic profiling in patients with resectable early-stage non-small-cell lung cancer.

Background: Identifying actionable driver mutations tissue-based comprehensive genomic profiling (CGP) is paramount in treatment decisions for metastatic non-squamous, non-small-cell lung cancer (NSCLC). However, the role of CGP remains elusive in resectable NSCLC. Here, we elucidate the feasibility of CGP in early-stage NSCLC Korean patients and compare the tumor mutational burden (TMB) and mutation landscape using three different platforms.

CD81 and CD82 expressing tumor-infiltrating lymphocytes in the NSCLC tumor microenvironment play a crucial role in T-cell activation and cytokine production.

Introduction: To understand the immune system within the tumor microenvironment (TME) of non-small cell lung cancer (NSCLC), it is crucial to elucidate the characteristics of molecules associated with T cell activation.

Methods: We conducted an in-depth analysis using single-cell RNA sequencing data obtained from tissue samples of 19 NSCLC patients. T cells were classified based on the Tumor Proportion Score (TPS) within the tumor region, and molecular markers associated with activation and exhaustion were analyzed in T cells from high TPS areas.

Prognostic Value of Mitral Annular Calcification in Liver Transplant Patients: Implication in Posttransplant Outcomes.

Background: With the rise of metabolic diseases and aging in liver transplant (LT) candidates, mitral annular calcification (MAC) is more recognizable. Despite cardiovascular risk becoming a leading cause of mortality in LT recipients, the influence of MAC remains unexamined. This study investigates the prevalence, related factors, and impact of MAC on LT outcomes.

Ginsenoside Rb1 alleviates lipopolysaccharide-induced inflammation in human dental pulp cells via the PI3K/Akt, NF-κB, and MAPK signalling pathways.

Aim: Among numerous constituents of Panax ginseng, a constituent named Ginsenoside Rb1 (G-Rb1) has been studied to diminish inflammation associated with diseases. This study investigated the anti-inflammatory properties of G-Rb1 on human dental pulp cells (hDPCs) exposed to lipopolysaccharide (LPS) and aimed to determine the underlying molecular mechanisms.

Methodology: The KEGG pathway analysis was performed after RNA sequencing in G-Rb1- and LPS-treated hDPCs.

Impact of preoperative nonselective beta-blocker use on acute kidney injury after living donor liver transplantation: Propensity score analysis.

Comparison of Fibrinogen Concentrate and Cryoprecipitate on Major Thromboembolic Events after Living Donor Liver Transplantation.

(1) Background: Liver transplantation (LT) is associated with significant hemorrhage and massive transfusions. Fibrinogen replacement has a key role in treating massive bleeding during LT and hypofibrinogenemia is treated by fibrinogen concentrate or cryoprecipitate. However, these two products are known to be associated with major thromboembolism events (MTEs).

Effect of Nefopam on Dysesthesia, Postoperative Pain, and Satisfaction in Patients with Lumbar Spinal Stenosis Undergoing Spine Surgery: A Double-Blind, Randomized Study.

Postoperative residual pain and dysesthesia in patients with lumbar spinal stenosis (LSS) can reduce patient satisfaction. We investigated the effects of nefopam on dysesthesia, postoperative pain, and satisfaction in patients with LSS who underwent spine surgery. A total of 73 patients were randomly assigned to two groups: the nefopam group ( = 35), receiving a 20 mL normal saline-based solution containing nefopam 20 mg, and the control group ( = 38), which received 20 mL of normal saline 1 h before the end of the operation.
