Skeletal muscle metabolic dysfunction with circulating carboxymethyl-lysine in dietary food additive-induced leaky gut.

Impaired intestinal permeability induces systemic inflammation and metabolic disturbance. The effect of a leaky gut on metabolism in skeletal muscle, a major nutrient consumer, remains unclear. In this study, we aimed to investigate the glucose metabolic function of the whole body and skeletal muscles in a mouse model of diet-induced intestinal barrier dysfunction.

High-intensity exercise impairs intestinal barrier function by generating oxidative stress.

The intestine functions as a barrier preventing the entry of extrinsic factors into the body. This barrier function is disrupted by oxidative damage along with an impaired mucosal layer. Excessive exercise can generate oxidative stress in the intestinal tissue; however, the effect of exercise-induced oxidative stress on intestinal permeability is unclear.

Thoracic mediastinal-occupying ratio predicts recovery and prognosis after lung transplantation.

Objectives: Even after transplantation of favourable donor lungs, some recipients require prolonged weaning from mechanical ventilation, indicating a poor prognosis. We investigated the effects of prolonged mechanical ventilation (PMV) for >14 days on the recovery and survival of patients who underwent cadaveric lung transplantation in relation to their physical traits.

Methods: We retrospectively reviewed patients who underwent cadaveric lung transplantation (age ≥15 years) at a single centre between April 2015 and December 2020 and classified them into PMV and non-PMV groups (>14 and ≤14 days of mechanical ventilation postoperatively, respectively).

Protein intake after the initiation of chemotherapy is an independent prognostic factor for overall survival in patients with unresectable pancreatic cancer: A prospective cohort study.

Background & Aims: This study was conducted to investigate the nutritional status and longitudinal dietary intake during the course of chemotherapy, and their relationships with the survival in patients with unresectable pancreatic cancer.

Methods: A prospective cohort study was conducted in 38 patients with unresectable pancreatic cancer receiving chemotherapy between January 2018 and November 2019. Subjective global assessment was used to assess the nutritional status, and the dietary intake was assessed monthly, for up to 12 months, using a brief self-administered diet history questionnaire.

Effect of dietary antioxidant-rich foods combined with aerobic training on energy metabolism in healthy young men.

Although supplementation with several antioxidants has been suggested to improve aerobic metabolism during exercise, whether dietary foods containing such antioxidants can exert the metabolic modulation is unclear. This study aimed to investigate the effect of intake of the specific antioxidant-rich foods coupled with exercise training on energy metabolism. Twenty young healthy, untrained men were assigned to antioxidant and control groups: participants in the antioxidant group were encouraged to consume foods containing catechin, astaxanthin, quercetin, glutathione, and anthocyanin.

Effect of downhill walking on next-day muscle damage and glucose metabolism in healthy young subjects.

This study aimed to investigate the effect of downhill walking on muscle damage and glucose metabolism in healthy subjects. All ten healthy young men and women (age, 24.0 ± 1.

Glutathione supplementation suppresses muscle fatigue induced by prolonged exercise via improved aerobic metabolism.

Backgrounds: Glutathione is an endogenous redox couple in animal cells and plays important roles in antioxidant defense and detoxification, although it is unknown if oral glutathione supplementation affects exercise-induced physiological changes. The present study investigated the effect of glutathione intake on exercise-induced muscle metabolism and fatigue in mice and humans.

Methods: ICR mice were divided into 4 groups: sedentary control, sedentary supplemented with glutathione (2.

The astaxanthin-induced improvement in lipid metabolism during exercise is mediated by a PGC-1α increase in skeletal muscle.

Astaxanthin, a xanthophyll carotenoid, accelerates lipid utilization during aerobic exercise, although the underlying mechanism is unclear. The present study investigated the effect of astaxanthin intake on lipid metabolism associated with peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) in mice. Mice were divided into 4 groups: sedentary, sedentary and astaxanthin-treated, exercised, and exercised and astaxanthin-treated.
