Background: Current evidence on the associations between insulin resistance (IR) and Helicobacter pylori (H. pylori) infection remains limited. This study aimed to investigate the association between non-insulin-based surrogate markers of IR, including the triglyceride glucose (TyG) index, triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio, and the metabolic score for IR (METS-IR), and H.

Fibroblast-like synoviocytes (FLSs) exhibit excessive proliferative and aggressive phenotypes and play a major role in the pathophysiology of RA. Previous studies have confirmed the pathologic role of L-selectin in cell adhesion and migration.

Age-related diseases are often linked to chronic inflammation. Senescent cells secrete inflammatory cytokines, chemokines and matrix metalloproteinases, collectively referred to as the senescence-associated secretory phenotype (SASP). The current study discovered that aging leads to the accumulation of senescent tendon stem/progenitor cells (TSPCs) in tendon tissue, resulting in the development of a SASP.

This study aims to explore the relationship between these biomarkers and the risk of CHD in T2DM patients and clarify their association with the CHD severity.
Methods: A total of 518 patients with T2DM who underwent coronary angiography (CAG) were included and categorized into either the T2DM group or the T2DM combined with CHD group based on the angiographic findings.
Objective: This prospective randomized controlled trial aimed to compare the effectiveness of functional jejunal interposition (FJI) and simple jejunal interposition (SJI) as reconstruction methods following total gastrectomy for gastric cancer. The study assessed primary endpoints such as nutritional status and quality of life, as well as secondary endpoints including operative time, intraoperative blood loss, perioperative and postoperative complications, and survival rate.
Methods: A total of 113 patients were randomly assigned to either the FJI group or the SJI group.
The objective of this study was to explore the potential of machine-learning techniques in the automatic identification and classification of brain metastases from a radiomic perspective, aiming to improve the accuracy of tumor volume assessment for radiotherapy. By using various machine-learning algorithms, including random forest, support vector machine, gradient boosting machine, XGBoost, decision tree, artificial neural network, k-nearest neighbors, LightGBM, and CatBoost algorithms, a stacking ensemble model was developed to classify gross tumor volume (GTV), brainstem, and normal brain tissue based on radiomic features. Multiple evaluation metrics, including the specificity, sensitivity, negative predictive value, positive predictive value, accuracy, Matthews correlation coefficient, and the Youden index, were used to assess the model's performance.

Vascular remodeling is the main pathological feature of pulmonary hypertension, but treatments for pulmonary hypertension are lacking. Determining the process of vascular proliferation and dysfunction may be a way to decipher the pathogenesis of pulmonary hypertension.

Aim: To predict the uninvolved liver dose in stereotactic body radiotherapy (SBRT) for liver cancer using a neural network-based method.
Methods: A total of 114 SBRT plans for liver cancer were used to test the neural network method.
Efflux pumps play a crucial role in the development of antibiotic resistance. The aim of this study was to investigate the relationship between efflux pump gene expression and resistance gene mutations in . Twenty-six clinical strains with varying resistance characteristics were selected for further experiment.

Dysfunction of TSPCs, due to aberrant activation of the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway, contributes to tendinopathy. Unfortunately, the effectiveness of conventional subcutaneous injection targeting at suppressing JAK/STAT signaling pathway is limited due to the passive diffusion of drugs away from the injury site.

The challenge lies in the scarcity of targeted therapies with substantial efficacy for DCM. Additionally, traditional anti-heart failure drugs are constrained due to hypotension propensity or limited symptom improvement.

RA cannot be fully cured and requires lengthy treatment, imposing a significant burden on both individuals and society. Due to the lack of specific drugs available for treating RA, exploring a key new therapeutic target for RA is currently an important task.

Yet, the literature lacks consistent evidence regarding the effects of grandparenting on the mental health of this cohort. Accordingly, this study aimed to explore the impact of grandparenting on the mental health of rural middle-aged and older adults, as well as the underlying mechanisms.

Background: In the context of the global aging challenge, an increasing number of middle-aged and older adults (MAOAs) are engaging in grandparenting. However, the effect of grandparenting on the mental health of caregivers has shown inconsistent findings. To effectively promote healthy aging, it is imperative to adopt a comprehensive perspective and employ a rigorous approach to further investigate the relationship between these two social phenomena.

However, prior research has often overlooked the connection between household consumption and long-term care insurance (LTCI). This study aims to investigate the influence of LTCI on consumption patterns within older Chinese households.

To investigate the underlying mechanisms, a greenhouse experiment was conducted with two temperature regimes [control treatment, 28 °C; high temperature (HT), 34 °C] for 7 d. Results showed HT did not significantly influence cotton yield, but reduced boll number and increased boll weight.

Herein, drought experiments were conducted using two cultivars of upland cotton (Gossypium hirsutum), Dexiamian 1 (drought-tolerant) and Yuzaomian 9110 (drought-sensitive). Results showed that drought notably reduced sucrose efflux from cottonseed coats to fibers by down-regulating the expression of GhSWEET10 and GhSWEET15 in outer cottonseed coats, leading to enhanced sucrose accumulation in cottonseed coats but decreased sucrose accumulation in fibers.

Here, we investigated the molecular mechanism underlying pyroptosis in T cells isolated from patients with RA. Compared with healthy individuals, patients with RA had more pyroptotic CD4 T cells in blood and synovia, which correlated with clinical measures of disease activity.

Purpose: To understand filial piety when caring for aging CCAs and conceptualize an operational definition and framework.
Methods: A systematic search was conducted in CINAHL, PubMed, Scopus, and PsycINFO databases.
Objective: Rheumatoid arthritis (RA) is a chronic, progressive autoimmune disease with a complex pathogenesis that has not yet been fully elucidated, and T-cell pyroptosis is an important pathogenetic factor in RA. This study aimed to investigate the role of endoplasmic reticulum aminopeptidase 2 (ERAP2) in the pyroptosis of CD4 T cells in RA and the specific molecular mechanism.
Methods: Peripheral venous blood was collected from human subjects, and CD4 T cells were isolated and activated to measure the level of pyroptosis and ERAP2 expression.
Increasing evidence shows that maternal hyperglycemia inhibits cardiomyocyte (CM) proliferation and promotes cell apoptosis during fetal heart development, which leads to cardiac dysplasia. Accumulating evidence suggests that the overexpression of miR-21 in CMs has a protective role in cardiac function. Therefore, we investigated whether miR-21 can rescue CM injury caused by high glucose.
