This study aims to estimate the disease burden of EOD, analyze the burden attributable to risk factors from 1990 to 2021, and project these trends to 2050 at global, regional, and national levels, providing essential data to inform public health policy.

Methods: By utilising data from the GBD 2021 database, this study analysed metrics such as age-standardized prevalence (ASPR), mortality (ASMR), and disability-adjusted life years (AS-DALYs) for EOD.

Increasing eccentric contraction duration enhances resistance exercise-induced inhibitory control improvement while reducing the exertion perception: A pilot study in young men.

Low-intensity resistance exercise with slow movement and tonic force generation (LRST) effectively improves cognitive inhibitory control (IC) while heightening the subjective perception, which is a barrier to exercise adherence. Compared with concentric (CON) contractions, eccentric (ECC) contractions have greater brain activation related to cognitive functions while decreasing subjective perception. Therefore, we examined whether LRST with a longer duration of ECC contraction (ECC-LRST) could further enhance exercise-induced IC improvement while reducing the subjective perception, compared with traditional LRST.

Reaction-Diffusion and Crystallization Kinetics Modulation of Two-Step Deposited Tin-Based Perovskite Film via Reducing Atmosphere.

The two-step deposition method effectively mitigates the efficiency decline observed in tin-based perovskite solar cells (TPVSCs) with increasing cell area, stemming from film in-homogeneity. However, the high solubility of SnI in the conventionally used solvent isopropyl alcohol, coupled with the absence of effective modulation of reaction-diffusion process, results in inadequate film coverage and conversion. In this study, we introduce formic acid as the second-step solvent and introduce dithiothreitol (DTT) to regulate reaction-diffusion/crystallization kinetics meticulously.

Targeting the NOTCH2/ADAM10/TCF7L2 Axis-Mediated Transcriptional Regulation of Wnt Pathway Suppresses Tumor Growth and Enhances Chemosensitivity in Colorectal Cancer.

[Research progress in stimuli-responsive microneedles for biomedical applications].

Conventional administration methods have problems including low bioavailability, complex operation process, and discomfort of patients with fear of needles. Transdermal delivery can avoid these problems, whereas most drugs are difficult to directly penetrate the skin cuticle and reach the diseased site. Microneedling is an emerging method of local drug delivery, enabling the drug penetration through the stratum corneum of the skin in a minimally invasive manner and delivering the drug directly to the diseased site, thereby improving the treatment effect.

Effect of dynamic high-pressure microfluidization on the structural, emulsifying properties, in vitro digestion and antioxidant activity of whey protein isolate.

The effects of dynamic high-pressure microfluidization (DHPM) on the structural, emulsifying properties, in vitro digestion and antioxidant activity of whey protein isolate (WPI) were investigated. The results demonstrated that WPI treated with 100 MPa DHPM exhibited superior emulsification performance. This can be attributed to the conformational changes induced by 100 MPa DHPM in WPI, leading to a transformation from disordered structures to ordered structures and an increased exposure of fluorophore such as tryptophan residues and hydrophobic groups, reduced aggregation state and particle size of WPI.
