Background: Type 2 diabetes (T2DM) is a chronic metabolic disorder characterized by insulin resistance and chronic inflammation. Adipose tissue macrophages (ATMs), central players in mediating pro-inflammatory responses within adipose tissue, have been shown to influence insulin sensitivity through exosome secretion. While the role of macrophages-derived exosomal miRNA has been studied in various diseases, their pathogenic roles in T2DM, particularly ATMs-derived exosomal miRNA in adipose tissue inflammation, remain underexplored.

Background: Congenital diarrheas and enteropathies (CODEs) caused by diacylglycerol transferase 1 (DGAT1) mutations often cause disease within 2 weeks after birth. If not treated properly, the disease can be life-threatening; therefore, early diagnosis and rational treatment strategies are essential. This study was conducted to improve the understanding of congenital diarrhea caused by DGAT1 deficiency.

The shape and extent of the plastic zone can effectively reflect the degree of deformation and failure of the surrounding rock. By applying complex variable functions and the theory of elasticity, a mechanical model for the surrounding rock of a rectangular roadway is established. The analytical solution for the stress in the surrounding rock of a rectangular roadway under a non-uniform stress field is derived, and the spatial stress distribution pattern in the surrounding rock of the rectangular roadway is obtained.

Atherosclerosis is a chronic inflammatory disease of the arterial wall caused by an imbalance of lipid metabolism and a maladaptive inflammatory response. A variety of harmful cellular changes associated with atherosclerosis include endothelial dysfunction, the migration of circulating inflammatory cells to the arterial wall, the production of proinflammatory cytokines, lipid buildup in the intima, local inflammatory responses in blood vessels, atherosclerosis-associated apoptosis, and autophagy. PTEN inhibits the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (PKB/AKT)/mammalian target of rapamycin (mTOR) pathway through its lipid phosphatase activity.

Acetone is a biomarker found in the expired air of patients suffering from diabetes. Therefore, early and accurate detection of its concentration in the breath of such patients is extremely important. We prepared Tin(IV) oxide (SnO) nanospheres via hydrothermal treatment and then decorated them with bimetallic PtAu nanoparticles (NPs) employing the approach of in situ reduction.

As the global aging population increases, the demand for rehabilitation of elderly hand conditions has attracted increased attention in the field of wearable sensors. Owing to their distinctive anti-electromagnetic interference properties, high sensitivity, and excellent biocompatibility, optical fiber sensors exhibit substantial potential for applications in monitoring finger movements, physiological parameters, and tactile responses during rehabilitation. This review provides a brief introduction to the principles and technologies of various fiber sensors, including the Fiber Bragg Grating sensor, self-luminescent stretchable optical fiber sensor, and optic fiber Fabry-Perot sensor.

Article Synopsis
  • The study focuses on comparing the deformation behavior and mechanical properties of anchor cables with C-shaped tubes versus regular anchor cables when subjected to shear conditions.
  • Double-sided shear tests reveal that the C-shaped tube changes the stress distribution within the anchor cables, reducing stress concentration and leading to primarily tensile failures.
  • A finite element analysis using ABAQUS was performed to model the stress interaction between the anchor cable, C-shaped tube, and concrete, and results indicate that the model accurately simulates stress distribution and damage in the prestressed anchored structure.

Background: IFN-induced protein 44-like (IFI44L) promoter methylation has been demonstrated to serve as an effective blood diagnostic biomarker for adult-onset SLE. However, its utility as a diagnostic marker for childhood-onset SLE (cSLE) remains to be verified.

Methods: Initially, we conducted a differential analysis of gene methylation and mRNA expression patterns in cSLE whole blood samples obtained from the public GEO database to determine IFI44L gene expression and assess the methylation status at its CpG sites.
