Introduction: The aim of the article is to investigate the beneficial effects of methylene blue (MB) on the acute phase of experimental corrosive esophageal burns.
Materials And Methods: A total of 21 male Sprague-Dawley rats were allocated into three groups with an equal number in each group. In Group 1 (control), the esophageal lumen was irrigated with saline. In Groups 2 (untreated) and 3 (MB treatment), the distal esophagus was burned with 30% NaOH solution. In Group 3, MB was applied locally on the distal esophageal lumen (30 mg/kg) 90 minutes after the burn. In all the groups, animals were humanely killed at the end of the 7th day. Distal esophageal specimens were obtained for histopathological and biochemical examinations.
Results: MB increased the tissue superoxide dismutase levels and the total antioxidant status, whereas it decreased the levels of the total oxidant status with significant attenuation of histopathological damage.
Conclusion: MB might have reduced the tissue damage in corrosive esophagitis because of its antioxidant effects.

Evidence regarding the relationship between free triiodothyronine (FT3) and low-density lipoprotein cholesterol (LDL-C) remains limited. This study aimed to evaluate the association between FT3 and LDL-C levels in patients with type 2 diabetes mellitus (T2DM) who exhibit normal thyroid function. Between June 2022 and October 2023, a total of 3011 inpatients with T2DM and euthyroid status were continuously and non-selectively recruited from a Chinese hospital.

Exposure to sound energy may be a risk factor or a therapeutic intervention for Alzheimer's disease (AD). On one hand, noise has a harmful effect on people with AD by contributing to hearing loss, sleep disturbance, oxidative stress, inflammation, and excitotoxicity. But on the other hand, clinical trials and nursing home interventions with soundscape augmentation involving natural sounds have shown promising results in alleviating psychophysiological symptoms in people with AD.

Hypothermic oxygenated machine perfusion (HOPE) preconditions liver grafts before transplantation. While beneficial effects on patient outcomes were demonstrated, biomarkers for viability assessment during HOPE are scarce and lack validation. This study aims to validate the predictive potential of perfusate flavin mononucleotide (FMN) during HOPE to enable the implementation of FMN-based assessment into clinical routine and to identify safe organ acceptance thresholds.

Background: Chronic hard-to-heal wounds, such as diabetic foot ulcers, venous leg ulcers, and pressure ulcers, present significant safety concerns, patient burdens, and challenges to health care systems globally.
Objective: To review the mechanism of action and clinical function of bromelain-based enzymatic debridement (BBD) in the context of wound care, focusing on the mechanism of action of BBD and its formulation for chronic wounds in particular.
Methods: A literature review was conducted to assess both bromelain's mechanism of action as well as clinical and preclinical studies on the use of BBD, searching the PubMed and Google Scholar databases for articles published between November 1992 and July 2024.
