Association between metabolic visceral fat score and left ventricular hypertrophy in individuals with type 2 diabetes.

Background: Left ventricular hypertrophy (LVH), a hallmark of early-stage heart failure (HF), is a common complication in individuals with type 2 diabetes mellitus (T2DM). Metabolic Visceral Fat Score (METS-VF), a novel metric for estimating visceral adiposity, may provide valuable insights into LVH risk. This study explores the association between METS-VF and LVH in T2DM and compare its predictive performance to traditional abdominal obesity indices.

Heterogeneity in clinical patterns of adult lung abscess patients: an 8-year retrospective study in a tertiary hospital.

Background: The widespread use of broad-spectrum antibiotics has led to changes in both the microbiological and clinical characteristics of lung abscesses. It is necessary to re-evaluate the bacterial spectrum associated with these infections. As a novel method for pathogen detection, metagenomic next-generation sequencing (mNGS) is increasingly being applied in clinical practice.

A bilayer scaffold of collagen and nanohydroxyapatite promotes osteochondral defect in rabbit knee joints.

Aims: A large number of surgical operations are available to treat osteochondral defects of the knee. However, the knee joint arthroplasty materials cannot completely mimic the articular cartilage and subchondral bone, which may bring some obvious side effects. Thus, this study proposed a biocompatible osteochondral repair material prepared from a double-layer scaffold of collagen and nanohydroxyapatite (CHA), consisting of collagen hydrogel as the upper layer of the scaffold, and the composite of CHA as the lower layer of the scaffold.

Effect of intercropping in orchards on soil quality in the canopy.

The cultivation of Lingwu jujube traditionally employs clean tillage, leaving substantial gaps between rows and exposing almost 60% of the orchard to the elements. This method promotes rapid soil moisture evaporation, exacerbates soil erosion, and deteriorates the soil's physicochemical properties. Consequently, there is a critical need for a more sustainable planting approach that optimally utilizes land resources.

SLC35C2 promotes stemness and progression in hepatocellular carcinoma by activating lipogenesis.

Metabolic reprogramming plays a critical role in tumorigenesis and progression, including hepatocellular carcinoma (HCC). The Solute Carriers (SLCs) family is responsible for the transport of a range of nutrients and has been linked to various cancers. Cancer stem cells (CSC) are a contributing factor to the recurrence and metastasis of HCC.

Metagenomic next-generation sequencing on treatment strategies and prognosis of patients with lower respiratory tract infections: A systematic review and meta-analysis.

Zn and Cl Coregulated MXene Catalyst Enhances Li-CO Battery Reversibility.

MXenes are promising cathodes for Li-CO batteries owing to their high electrical conductivity and efficient CO activation function. However, the effects of adsorption and electronic structures of MXene on the full life cycle of Li-CO batteries have been rarely investigated. Here, we employ a coregulation approach to enhance the adsorption-decomposition of lithium carbonate (LiCO) by introducing Zn and Cl surface groups onto the TiC MXene (Zn-TiCCl) catalyst.

Accurate Diagnosis of Lower Respiratory Infections Using Host Response and Respiratory Microbiome from a Single Metatranscriptome Test of Bronchoalveolar Lavage Fluid.

Lower respiratory tract infections (LRTIs) diagnosis is challenging because noninfectious diseases mimic its clinical features. The altered host response and respiratory microbiome following LRTIs have the potential to differentiate LRTIs from noninfectious respiratory diseases (non-LRTIs). Patients suspected of having LRTIs are retrospectively enrolled and a clinical metatranscriptome test is performed on bronchoalveolar lavage fluid (BALF).

Machine Learning-Engineered Nanozyme System for Synergistic Anti-Tumor Ferroptosis/Apoptosis Therapy.

Nanozymes with multienzyme-like activity have sparked significant interest in anti-tumor therapy via responding to the tumor microenvironment (TME). However, the consequent induction of protective autophagy substantially compromises the therapeutic efficacy. Here, a targeted nanozyme system (Fe-Arg-CDs@ZIF-8/HAD, FZH) is shown, which enhances synergistic anti-tumor ferroptosis/apoptosis therapy by leveraging machine learning (ML).
