To further enhance the bandwidth of an integrated chaotic semiconductor laser, a structure of an integrated mutual coupling laser is proposed. The laser integrates two distributed feedback lasers and two semiconductor optical amplifiers in the middle of the lasers. The dynamic state of the integrated laser undergoes complex changes with the variation of the bias currents of the distributed feedback (DFB) lasers and semiconductor optical amplifiers (SOAs).

Nanozymes with biological enzyme activity show great promise in biochemical analysis and medicine, yet single-activity nanozymes were limited by low catalytic efficiency and strict catalytic environment requirements. Consequently, the development of nanozymes with multiple enzyme activities presents a significant challenge. In the work, a vanadium-capped polyoxometalates (POMs)-encapsulating metal-organic framework (MOF), [Cu(Trz)Cl][PMoO(VO)], was synthesized via hydrothermal synthesis, which shows multiple enzyme activities concluding oxidase (OXD), peroxidase (POD) and catalase (CAT) activities.

Exoskeletons have been shown be able to reduce metabolic cost of human walking. Determining the suitable assistance is challenging due to individual variability in response and the need for tailored assistance across different gait conditions. Human-in-the-loop (HIL) optimization has been proposed to address this issue, but current implementations often suffer from prolonged optimization cycles.

Behçet's uveitis (BU) is a severe ocular manifestation of Behçet's disease, typically accompanied by abnormal neutrophil infiltration and hyperactivation. However, the underlying causes of excessive neutrophil extracellular traps (NETs) production and mechanisms by which NETs contribute to the pathogenesis of BU remain incompletely understood. Neutrophils from BU patients exhibit a higher propensity for NETs release compared to healthy controls.

Carrying external loads, such as vest-borne systems, is common in occupations like firefighting and military service, yet the physiological impacts of load placement, mass, and walking conditions remain not fully understood. This study examined the effects of vest load carriage on metabolic rate and heart rate. Participants underwent three trials with varying load placements, masses (0-30 kg), and walking conditions (different speeds and inclines).

During gastrulation, Wnt-β-catenin signaling dictates lineage bifurcation generating different mesoderm cell types. However, the specific role of Wnt receptors in mesoderm specification remains elusive. Using selective Frizzled (FZD) and LRP5/6 antibody-based agonists, we examined FZD receptors' function during directed mesoderm differentiation of human pluripotent stem cells (hPSCs).

Objectives: The objective of this study was to evaluate the role of Liver Stiffness Measurement (LSM) and serum transaminase levels for predicting early allograft failure (EAF) after liver transplantation (LT).

Methods: A total of 189 patients who underwent LT were prospectively recruited in the study. Of these patients, 13 cases died or received re-transplantation within 90 days after surgery were classified as EAF group, while rest 176 patients were included in the non-EAF group.

Lysine lactylation plays critical roles in various diseases, including cancer. Our previous study showed that lactylation of non-histone ABCF1 may be involved in hepatocellular carcinoma (HCC) progression. In this study, we evaluated the prognostic value of ABCF1-K430la in HCC using immunohistochemical staining and performed amino acid point mutations, multi-omics crossover, and biochemical experiments to investigate its biological role and underlying mechanism.

Micro- and nanorobots excel in navigating the intricate and often inaccessible areas of the human body, offering immense potential for applications such as disease diagnosis, precision drug delivery, detoxification, and minimally invasive surgery. Despite their promise, practical deployment faces hurdles, including achieving stable propulsion in complex in vivo biological environments, real-time imaging and localization through deep tissue, and precise remote control for targeted therapy and ensuring high therapeutic efficacy. To overcome these obstacles, we introduce a hydrogel-based, imaging-guided, bioresorbable acoustic microrobot (BAM) designed to navigate the human body with high stability.

Cancer-intrinsic immune evasion mechanisms and pleiotropy are a barrier to cancer immunotherapy. This is apparent in certain highly fatal cancers, including high-grade gliomas and glioblastomas (GBM). In this study, we evaluated two murine syngeneic glioma models (GL261 and CT2A) as preclinical models for human GBM using functional genetic screens, single-cell transcriptomics and machine learning approaches.

Aim: The term MetALD has been introduced to describe individuals who have metabolic dysfunction-associated steatotic liver disease (MASLD) with greater alcohol consumption, according to the new nomenclature for steatotic liver disease (SLD). This study aims to evaluate the prevalence and clinical characteristics of MetALD in the general population.

Methods: This study is a retrospective, cross-sectional analysis that utilizes the population-based data from the Korea National Health and Nutrition Examination Survey (KNHANES) undertaken between 2019 and 2021.

Article Synopsis
  • The study aimed to create and validate a prediction model that identifies microvascular invasion (MVI) in patients with single hepatocellular carcinoma (HCC) tumors smaller than or equal to 5 cm using ultrasound and biochemical indicators.
  • Data was collected from 318 patients over 18 months, utilizing various ultrasound techniques and biochemical tests to identify independent predictors of MVI, which were then analyzed through logistic regression.
  • Key findings revealed specific ultrasound features and a biochemical marker (PIVKA-II) were strongly associated with MVI, and the combined model demonstrated high accuracy and reliability for preoperative predictions.

Introduction: Currently, there are two types of percutaneous arteriovenous fistula (pAVF) formation systems approved by the FDA: Ellipsys and WavelinQ. Although these systems are already in use in Europe or the United States, they have not been approved for use in Korea yet. For this reason, this study aimed to check anatomical feasibility of these systems for Korean population prior to their actual use.
