Chemical systems do not allow the coupling of energy from several simple reactions to drive a subsequent reaction, which takes place in the same medium and leads to a product with a higher energy than the one released during the first reaction. Gibbs energy considerations thus are not favorable to drive e.g., water splitting by the direct oxidation of glucose as a model reaction. Here, we show that it is nevertheless possible to carry out such an energetically uphill reaction, if the electrons released in the oxidation reaction are temporarily stored in an electromagnetic system, which is then used to raise the electrons' potential energy so that they can power the electrolysis of water in a second step. We thereby demonstrate the general concept that lower energy delivering chemical reactions can be used to enable the formation of higher energy consuming reaction products in a closed system.

Diabetic cardiomyopathy (DCM) is one of the most lethal complications of diabetes and is induced by the overproduction of reactive oxygen species (ROS) in cardiomyocytes due to sustained high glucose levels, leading to cardiac oxidative damage and final sudden death. Drugs and antioxidants currently applied to the clinical therapy of DCM fail to scavenge ROS efficiently, resulting in compromised therapeutic efficacy. Herein, a nanocatalytic antioxidative therapeutic strategy is proposed for DCM treatment.

Introduction: Cardiovascular disease (CVD) is a leading cause of mortality on a global scale, with a higher prevalence observed among men. This study investigated the protective effect of vitamin D supplementation on CVD.
Methods: A cohort of thirty mice was divided into three groups: control, T1 diabetic, and T1 diabetic groups that received vitamin D treatment.

Background: Diabetes mellitus and periodontitis are two common chronic diseases with bidirectional relationship. Considering the role of oxidative stress in the pathogenesis of these two diseases, the use of nutritional supplements with antioxidant properties can be useful. The purpose of this study was to determine the effectiveness of daily synbiotic supplement in the management of patients with type 2 diabetes mellitus (T2DM) and periodontal disease (PD) under non-surgical periodontal therapy (NSPT).

Constipation is correlated with diminished cognitive function, revealing a possible rectum-brain connection. In this counter-balanced crossover trial, 13 elite triathletes underwent a Stroop test to assess cognitive function and executive control. The Stroop test was conducted both with and without magnesium oxide intake, with a 1-week washout period between sessions.
