Jugular Vein Evans Blue Injection for Blood-Brain Barrier Assessment Following Hemorrhagic Stroke in a Mouse Model.

The blood-brain barrier (BBB) is a selectively permeable membrane that plays a crucial role in protecting the brain from harmful substances. Its disruption is associated with various central nervous system (CNS) disorders, including hemorrhagic stroke. Evans Blue (EB) dye, a protein-binding tracer, is commonly used to assess BBB permeability.

Association between olfactory dysfunction and gustatory dysfunction: evidence from the National Health and Nutrition Examination Survey.

Background: Olfactory dysfunction (OD) and gustatory dysfunction (GD) are common among adults, with prevalence increasing significantly in older age groups. Both dysfunctions have negative effects on appetite, nutrition, social functioning and even environmental safety. OD and GD frequently coexist, indicating a possible close association between these conditions.

Effect of Limosilactobacillus fermentum NCU001464 fermentation on physicochemical properties, xanthine oxidase inhibitory activity and flavor profile of Pueraria Lobata.

This study examined the impact of Limosilactobacillus fermentum NCU001464 fermentation on physicochemical properties, xanthine oxidase inhibitory activity, and the flavor profile of Pueraria Lobata (PL). An orthogonal experiment determined the optimum conditions: inoculation amount of 6 %, a fermentation time of 32 h, and a fermentation temperature of 37 °C. Under these conditions, fermented PL exhibited significantly higher antioxidant capacity and xanthine oxidase inhibition ability than unfermented PL, possibly because of increased total flavonoid content from 1.

Inhibition, Gastritis Attenuation, and Gut Microbiota Protection in C57BL/6 Mice by NCUH062003.

(), one of the most prevalent pathogenic bacteria worldwide, is the leading cause of gastritis, gastric intestinal metaplasia, and gastric cancer. Antibiotics, the conventional treatment for eliminating , often lead to severe bacterial resistance, gut dysbiosis, and hepatic insufficiency and fail to address the inflammatory response or gastric mucosal damage caused by infection. In this study, based on 10-week animal experiments, two models of NCUH062003 for the prophylaxis and therapy of infection in C57BL/6 mice were established; a comprehensive comparative analysis was performed to investigate the anti- effect of probiotics, the reduction in inflammation, and repair of gastric mucosal damage.

Charge Regulation-Enhanced Type I Photosensitizer-Loaded Hydrogel Dressing for Hypoxic Bacterial Inhibition and Biofilm Elimination.

Biofilm-induced chronic bacterial infections represent a significant challenge in modern medicine due to their resistance to conventional antibiotic treatments. Although photodynamic therapy (PDT) has emerged as a promising antibiotic-free antibacterial strategy, the hypoxic condition within biofilms and the lack of an effective local drug delivery system have limited the clinical effectiveness of photosensitizer (PS) agents. Herein, we propose a type of charge regulation-enhanced type I PS-loaded hydrogel dressing for treating biofilm infection.

Impact of different weaning strategies of high-frequency ventilation (HFV) on neonatal cerebral oxygen saturation and hemodynamics: protocol for a prospective randomized controlled trial.

Background: High-frequency ventilation (HFV) is commonly used in neonatal intensive care units to provide respiratory support for critically ill neonates. Currently, there is no standardized procedure for weaning from HFV. Two commonly used strategies are transitioning from HFV to conventional mechanical ventilation (CMV) before extubation (HFV-CMV) and extubation after decreasing mean airway pressure during HFV (HFV-HFV).
