Long-term correction of hemophilia A via integration of a functionally enhanced FVIII gene into the AAVS1 locus by nickase in patient-derived iPSCs.

Hemophilia A (HA) is caused by mutations in coagulation factor VIII (FVIII). Genome editing in conjunction with patient-derived induced pluripotent stem cells (iPSCs) is a promising cell therapy strategy, as it replaces dysfunctional proteins resulting from genetic mutations with normal proteins. However, the low expression level and short half-life of FVIII still remain significant limiting factors in the efficacy of these approaches in HA.

Application of fluorescence i-motif DNA silver nanocluster sensor to visualize endogenous reactive oxygen species in plant cells.

A novel fluorescent i-motif DNA silver nanoclusters system has been developed for visualization of reactive oxygen species in plants, enabling the detection of intracellular signaling in plant cells. Reactive oxygen species (ROS) are crucial in plant growth, defense, and stress responses, making them vital for improving crop resilience. Various ROS sensing methods for plants have been developed to detect ROS in vitro and in vivo.

Comparison of high-flow nasal oxygenation and standard low-flow nasal oxygenation during rigid bronchoscopy: a randomized controlled trial.

Background: The efficacy of high-flow nasal oxygenation (HFNO) in improving oxygenation is influenced by several factors, and its effectiveness is not always guaranteed. Therefore, we aimed to compare the effects of HFNO and standard low-flow nasal oxygenation during rigid bronchoscopy in the apneic patients.

Methods: All patients were administered general anesthesia with full muscle relaxation and were randomly assigned to receive either HFNO (HFNO group) or standard low-flow oxygenation (Standard group).

Comparison and validation of several scoring systems for non-variceal upper gastrointestinal bleeding: a retrospective study.

Various scoring systems have been developed to predict outcomes in patients with non-variceal upper gastrointestinal bleeding (NVUGIB). However, their accuracy remains unclear. This study aimed to compare and validate the predictive performance of several established scoring systems in patients with NVUGIB: Glasgow-Blatchford score (GBS) and the age, blood tests, and comorbidities (ABC), mental status-anesthesiologist score-pulse-albumin-systolic blood pressure-hemoglobin (MAP(ASH)), Japanese, and Charlson comorbidity index-in-hospital onset-albumin-mental status-Eastern Cooperative Oncology Group performance status-steroids (CHAMPS) scores.

Identification of Plasma Protein Biomarkers for Predicting Lung Cancer.

Background/aim: Lung cancer remains a leading cause of cancer-related mortality worldwide, necessitating the development of effective early diagnostic strategies. Despite advancements in imaging and screening technologies, late-stage diagnoses remain common, limiting treatment options and reducing survival rates. Thus, there is a critical need for reliable, minimally invasive biomarkers to improve early detection and patient outcomes.

Macrofollicular subtype of papillary thyroid carcinoma: Ultrasonographic findings and clinical implications.

The macrofollicular subtype of papillary thyroid cancer (MFS-PTC) is a rare subtype often leading to a challenging diagnosis. To evaluate the ultrasonographic (US) features and clinical implication of MFS-PTC. Records of 14 patients histologically diagnosed with MFS-PTC at our institution over a period of 16 years were retrospectively reviewed.

Optimizing venous anastomosis for forearm loop arteriovenous grafts: A comparative analysis of elbow veins and upper arm basilic veins in end-stage kidney disease patients.

Introduction: Optimizing vascular access for hemodialysis in end-stage kidney disease is crucial. While arteriovenous fistulas (AVFs) are preferred for better patency and fewer complications, many patients require alternatives options like arteriovenous grafts (AVGs) due to anatomical constraints. This study compares outcomes between elbow and upper arm (UA) basilic veins for forearm loop AVGs, highlighting the potential benefits of the UA basilic vein to improve patency and feasibility in patients with poor elbow veins through retrospective analysis.

Prediction of hearing recovery with deep learning algorithm in sudden sensorineural hearing loss.

This study aimed to establish a deep learning-based predictive model for the prognosis of idiopathic sudden sensorineural hearing loss (SSNHL). Data from 1108 patients with SSNHL between January 2015 and May 2023 were retrospectively analyzed. Patients underwent standardized treatment protocols including high-dose steroid therapy and hearing outcomes were assessed after three months using Siegel's criteria and the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) classification.

Integrating Vascular Phenotypic and Proteomic Analysis in an Open Microfluidic Platform.

This research introduces a vascular phenotypic and proteomic analysis (VPT) platform designed to perform high-throughput experiments on vascular development. The VPT platform utilizes an open-channel configuration that facilitates angiogenesis by precise alignment of endothelial cells, allowing for a 3D morphological examination and protein analysis. We study the effects of antiangiogenic agents─bevacizumab, ramucirumab, cabozantinib, regorafenib, wortmannin, chloroquine, and paclitaxel─on cytoskeletal integrity and angiogenic sprouting, observing an approximately 50% reduction in sprouting at higher drug concentrations.
