Structure characterization and preliminary immune activity of a glucomannan purified from Allii Tuberosi Semen.

A novel glucomannan, named ATSW-1, was obtained from Allii Tuberosi Semen by ion and gel permeation chromatography purification. Its structure was characterized using high-performance chromatography, Fourier transform infrared spectroscopy, gas chromatography-mass spectrometry, and nuclear magnetic resonance spectroscopy. The in vitro immune activities of ATSW-1 were examined using the Cell Counting Kit-8, the neutral red phagocytosis assay, and the secretion of related cytokines.

Dual antiplatelet therapy after minor strokes or high-risk TIA: Evidence from the Austrian stroke registry.

Background And Purpose: Three large, randomized trials demonstrated the benefit of short-term dual antiplatelet therapy (DAPT) versus monotherapy after non-cardioembolic minor stroke or high-risk transient ischemic attack (TIA). The aim of this study was to evaluate effects of DAPT versus monotherapy on functional outcomes and safety in a real-life setting.

Methods: Patients with minor stroke (NIHSS <4) or high-risk TIA (ABCD2 score ≥4) of non-cardioembolic origin without major vessel occlusion or revascularization therapy (thrombolysis or thrombectomy) treated between 2018 and 2023 were analyzed based on a prospective nationwide stroke unit registry.

Frailty assessment in geriatric trauma patients: comparing the predictive value of the full and a condensed version of the Fried frailty phenotype.

Background: Frailty is associated with multiple negative outcomes in geriatric trauma patients. Simultaneously, frailty assessment including physical measurements for weakness (grip strength) and slowness (gait speed) poses challenges in this vulnerable patient group. We aimed to compare the full 5-component Fried Frailty Phenotype (fFP) and a condensed model (cFP) without physical measurements, with regard to predicting hospital length of stay (LOS) and discharge disposition (DD).

Effect of vitamin D3, omega-3 fatty acids, and exercise on serum sclerostin levels and bone turnover markers.

Context: Sclerostin inhibits canonical Wnt signaling, a pathway promoting bone formation. The effects of vitamin D3, omega-3 fatty acids (omega-3s), and exercise on serum sclerostin levels and bone metabolism are unclear.

Objective: To investigate the effects of 2000 IU/d vitamin D3, 1g/d omega-3s, and a simple home-based strength exercise program (SHEP), alone or in combination, on serum sclerostin and bone turnover marker levels.

Phenological divergence between plants and animals under climate change.

Climate change has altered the timing of recurring biological cycles in both plants and animals. Phenological changes may be unequal within and among trophic levels, potentially impacting the intricate interactions that regulate ecosystem functioning. Here we compile and analyse a global dataset of terrestrial phenological observations, including nearly half a million time series for both plants and animals.
