Multifidus fat infiltration negatively influences the postoperative outcomes in lumbar disc herniation following transforaminal approach percutaneous endoscopic lumbar discectomy.

Purpose: This study aims to investigate the influence of multifidus muscle fat infiltration on clinical outcomes in lumbar disc herniation (LDH) undergoing percutaneous endoscopic lumbar discectomy (PELD).

Methods: A retrospective analysis was conducted on 224 patients who underwent lateral PELD, with complete one-year follow-up data. Patients were divided into two groups based on preoperative MRI evaluation of L4 multifidus muscle fat infiltration: a mild group (< 25%) and a severe group (≥ 25%).

Regulating the macroscopic and microscopic self-assembly behavior of hydroxybutyl chitosan based on alkyl distribution.

Hydroxybutyl chitosan (HBC), a derivative of chitosan, exhibits biocompatibility and temperature-sensitive properties, rendering it utilized in tissue engineering, and biomedical science. Currently, HBC is mainly prepared based on heterogeneous and homogeneous reactions. However, the impact of reactions on structure of derivatives and their mechanisms for self-assembly remains to be elucidated.

Gut microbiota may modify the association between dietary polyphenol intake and circulating levels of hippuric acid: results from a 1-year longitudinal study in China.

Background: Hippuric acid (HA), a host-microbe co-metabolite, normally derives from gut microbial catabolism of dietary polyphenols.

Objectives: We investigated the potential interplay between dietary polyphenols and gut microbiota on circulating HA levels, and examined the associations between serum concentrations of HA and cardiometabolic risk markers.

Methods: In a 1-year cohort of 754 community-dwelling adults, serum HA and its precursor [benzoic acid (BA)] and fecal microbiota were assayed using liquid chromatography-tandem mass spectrometry and 16S ribosomal RNA sequencing, respectively.

Association of volatile organic compound metabolites with hearing loss: unveiling their potential mechanism and intervention target.

Hearing loss (HL) is an otolaryngology disease susceptible to environmental pollutants. Volatile organic compounds (VOCs), as a class of chemical pollutants with evaporation propensity, pose a great threat to human health. However, the association between VOCs and HL remains unclear.

Effects of microbial fermentation on the anti-inflammatory activity of Chinese yam polysaccharides.

In this study, Chinese yam polysaccharides (CYPs) were fermented using M616, and changes in the chemical composition, structure, and anti-inflammatory activity of CYPs before and after fermentation were investigated. The carbohydrate content of M616-fermented CYP (CYP-LP) increased from 71.03% ± 2.
