Background: After head and neck cancer surgery with free flap reconstruction, the use of glucocorticoids is often required to alleviate inflammation and edema. However, the impact of glucocorticoid on postoperative complications and cancer progression remains unclear.
Methods: This retrospective cohort study included 711 elderly patients who underwent head and neck cancer surgery with free flap reconstruction at Shanghai Ninth People's Hospital from January 1, 2014, to December 31, 2022.
Introduction: Image-based diagnostic tools that aid endoscopists to biopsy putative esophageal malignant lesions are essential for ensuring the standardization and quality of Lugol's chromoendoscopy. But there's no such model available yet.
Methods: We developed a diagnostic model using endoscopic Lugol-unstained lesions (LULs) features and baseline data from 1099 individuals enrolled from a large-scale population-based ESCC screening cohort.
Redox imbalance induced by the accumulation of reactive oxygen species (ROS) accelerates age-related processes, often accompanied by a decrease in circadian rhythm amplitude. However, the underlying mechanisms by which ROS modulate circadian rhythms remain poorly understood. In this study, we found that ROS disrupt circadian rhythms in both zebrafish, as indicated by changes in diurnal behavior and clock gene expression, and in a human cell model.

Notably, resistance exercise has demonstrated significant improvements in muscle strength, coordination, and overall functional recovery. However, to optimize clinical management and mimic exercise-like effects, it is imperative to obtain a comprehensive understanding of the molecular alterations that underlie these positive effects.

Introduction: The role of individual nutrients including vitamins and minerals in cognitive function gained increasing attention in recent years. With regard to the association between dietary minerals and cognitive function, the results of human studies are inconclusive. The objective of this study was to explore the association between mineral intake and cognitive function using the data from Shanghai Health and Nutrition Survey (SHNS) in 2018.

Since the origin of this increased lactate is unknown, here we assessed associations between metabolic pathways and postoperative dNCR.
Methods: This study included 43 patients (≥60 years old) who had surgery under general anesthesia.

Background & Aims: The aim of this study was to investigate the persistence of Lugol-unstained lesions (LULs) in the esophagus detected by chromoendoscopy and explore their association with progression to malignancy.
Methods: We enrolled 647 participants from a population-based screening trial who had biopsied LULs at the baseline chromoendoscopy and underwent a chromoendoscopy re-examination after a median of 4.39 years.
Introduction: The fragile brain includes both the developing brain in childhood and the deteriorating brain in elderly. While the effects of general anesthesia on the myelin sheath of developing brain have been well-documented, limited research has explored its impact on degenerating brain in elderly individuals.
Methods: In our study, aged marmosets in control group were only anesthetized with 6-8% sevoflurane and 100% oxygen (2 L/min) for 1-2 min for anesthesia induction.
Light serves as a crucial external zeitgeber for maintaining and restoring physiological homeostasis in most organisms. Disrupting of light rhythms often leads to abnormal immune function, characterized by excessive inflammatory responses. However, the underlying regulatory mechanisms behind this phenomenon remain unclear.
View Article and Find Full Text PDFT-2 toxin (T-2), an A-type mono mycotoxin produced by various Fusarium species, disrupts DNA/RNA and protein synthesis upon entering the body, resulting in pathological conditions in various tissues/organs and posing a significant threat to human and animal health. However, the mechanisms underlying its toxicity remain unclear. With the goal of learning how T-2 affects reproduction in animals, we utilized primary porcine ovarian granulosa cells (pGCs) as a carrier in vitro and constructed concentration models for analyzing cell morphology and RNA-sequencing (RNA-seq).

The self-efficacy of TAs can substantially impact their performance. Nevertheless, little research has focused on the change in TAs' self-efficacy following their training.
View Article and Find Full Text PDFGenomic studies in animal breeding have provided a wide range of references; however, it is important to note that genes and mRNA alone do not fully capture the complexity of living organisms. Protein post-translational modification, which involves covalent modifications regulated by genetic and environmental factors, serves as a fundamental epigenetic mechanism that modulates protein structure, activity, and function. In this review, we comprehensively summarize various phosphorylation and acylation modifications on metabolic enzymes relevant to energy metabolism in animals, including acetylation, succinylation, crotonylation, β-hydroxybutylation, acetoacetylation, and lactylation.

Methods: A total of 423 patients who underwent valvular replacement surgery from January 2015 to December 2020 were enrolled. A comprehensive database that incorporated demographic characteristics, clinical conditions, and results of preoperative biochemistry tests was used for establishing the models.
Beyond its well-established role in diabetes management, metformin has gained attention as a promising therapeutic for inflammation-related diseases, largely due to its antioxidant capabilities. However, the mechanistic underpinnings of this effect remain elusive. Using in vivo zebrafish models of inflammation, we explored the impact of metformin on neutrophil recruitment and the underlying mechanisms involved.

However, the effectiveness of this approach remains uncertain, particularly among the Chinese population.
Methods: A cross-sectional study was conducted within 22 communities in Beijing, China between 2015 and 2018, with a total of 1099 participants recruited.

Bisphenol A (BPA) and its substitutes are widely used in daily life. Animal and cell line experiments have confirmed the effects of bisphenols on oxidative stress and inflammation. However, current population evidence for the effects of BPA alternatives, such as bisphenol F (BPF) and bisphenol S (BPS), on oxidative stress and inflammation is still sparse.
View Article and Find Full Text PDFDiet is an important source of perfluoroalkyl and polyfluoroalkyl substance (PFAS) exposure, and the dietary inflammatory index (DII) is a tool used to assess the inflammatory potential of an individual's diet. However, limited research has explored the association between the DII and PFAS exposure in humans. This study is the first to analyze the association between the five PFASs and DII using the National Health and Nutrition Examination Survey (NHANES) 2007-2018 database.

However, the rhythmic characteristics and underlying mechanisms of neutrophil migration on a 24-h timescale are largely unknown. Using the advantage of in vivo imaging of zebrafish, this study explored how the circadian gene clock1a dynamically regulates the rhythmic recruitment of neutrophils to inflammatory challenges.

However, the histopathologic diagnosis derived from tissue biopsies may be subject to underestimation of severity.
Methods: 1073 participants from whom biopsies were taken at baseline chromoendoscopic examination in a population-based screening trial were enrolled in this study.
Introduction: This study aimed to evaluate the impact of Lugol-unstained lesion (LUL) location on the detection yield, which may help the endoscopist select targets for biopsy.
Methods: We enrolled 1064 subjects who had LULs at the baseline screening of a population-based randomized controlled trial. There were 1166 LULs with recorded location and pathologic diagnosis, and these were used for analysis.
