Background: Obesity and type 2 diabetes mellitus (T2DM) are often accompanied with a disrupted diurnal rhythm of eating and sustained anabolic state, leading to metabolic inflexibility. In the present study, we plan to investigate effects of a sodium glucose co-transporter 2 (SGLT2) inhibitor, canagliflozin (CANA), on such a metabolic inflexibility, especially on fat metabolism, in the obese type 2 diabetic rats.
Materials And Methods: Five-week-old male SDT (Spontaneously Diabetic Torii) fatty rats as a model of obesity and T2DM and Sprague-Dawley (SD) rats were treated by either CANA (10 mg/kg) or saline (vehicle) orally for 14 days.
Purpose: The ileal bile acid transporter inhibitor elobixibat was recently approved in Japan for use in the treatment of patients with chronic constipation. Elobixibat has been associated with increased plasma glucagon-like peptide 1 level through Takeda G protein receptor 5, which is a membrane receptor of bile acids. The present study assessed the metabolic effects of elobixibat in patients with type 2 diabetes mellitus (T2DM)-related constipation.

This study aimed to investigate the effect of SGLT2 inhibitor on insulin sensitivity in the early phase of treatment initiation.
Methods And Results: This single-center, open label, and single-arm prospective study recruited 20 patients (14 men) with type 2 diabetes mellitus (T2DM).
Most childhood cancer survivors who undergo hematopoietic stem cell transplantation subsequently develop impaired glucose tolerance and hypertriglyceridemia. These conditions are presumably associated with total-body irradiation-related acquired lipodystrophy and may lead to cardiovascular disease. Metreleptin (recombinant leptin) may help improve the lipoprotein profile, insulin sensitivity, and quality of life of patients with total-body irradiation-related lipodystrophy.

Ghrelin is known to be involved in the brain reward circuits via dopamine neurons related to motivational properties. We investigated the relevance of ghrelin as an initiator of voluntary exercise as well as feeding behavior.

The enzyme was purified by ammonium sulfate fractionation, ion-exchange, hydrophobic, and gel filtration. TmEgl5A showed a molecular mass of approximately 40 kDa as determined by SDS-PAGE.

Furthermore, we assessed the possible protective effect of ketone bodies against the endothelial cell damage caused by glucose deficiency.
Methods: Human umbilical vein endothelial cells (HUVECs) were cultured at a glucose level of either 0.
Previously, we have shown that the adipocyte-specific nuclear form of sterol regulatory element-binding protein-1c (nSREBP-1c) transgenic mice spontaneously developed hepatic lesions that are similar to those of human nonalcoholic steatohepatitis (NASH) with a concomitant elevation of plasma TNF-α. In this study, we analyzed the role of TNF-α in the progression of nonalcoholic fatty liver disease (NAFLD). We established a Tnf knockout nSREBP-1c transgenic mouse line.

The aim of this study is to investigate the effects of metformin on energy metabolism and anthropometric factors in both human subjects and rats.
Methods: In human studies, metformin (1500mg/day) was administered to 23 healthy subjects and 18 patients with type 2 diabetes for 2 weeks.
Objective: Type 2 diabetes is a progressive disease characterized by insulin resistance and insulin secretory dysfunction. In this study, we assessed the factors contributing to an insulin secretory defect in type 2 diabetes patients.
Methods: The subjects consisted of 382 patients with type 2 diabetes, aged 57±13 years.
In the present study, effects of voluntary exercise in an obese animal model were investigated in relation to the rhythm of daily activity and ghrelin production. Male Sprague-Dawley rats were fed either a high fat diet (HFD) or a chow diet (CD) from four to 16 weeks old. They were further subdivided into either an exercise group (HFD-Ex, CD-Ex) with a running wheel for three days of every other week or sedentary group (HFD-Se, CD-Se).

Glargine showed lower post-dinner and bedtime glucose levels in Type 1 diabetes, and lower pre-dinner and post-dinner glucose levels in Type 2 diabetes than detemir.
