Interactions between β-lactoglobulin (β-lg) and epigallocatechin-3-gallate (EGCG) may modulate their health benefits. The objective of this study was therefore to investigate the synergistic effect of consuming β-lg and EGCG complexes on glucose tolerance of C57BL/6 male mice given an oral glucose tolerance test (OGTT) and randomized to one of the following treatments administered prior to the OGTT: 1) simulated milk ultrafiltrate (SMUF(-)), 2) SMUF(-) + EGCG, 3) SMUF(-) + β-lg, 4) SMUF(-) + EGCG + β-lg, 5) SMUF + calcium (SMUF(+)) and 6) SMUF(+) + EGCG + β-lg. We found no significant between-group difference in postprandial glucose response. However, when mice were separated in those who received β-lg from those who did not, we found that the latter displayed significantly higher postprandial glucose concentrations. Our results support the beneficial impact of β-lg on glycemic control and suggest that concomitant EGCG or calcium consumption does not improve this effect.

Background: Increased glucagon levels are now recognized as a pathophysiological adaptation to counteract overnutrition in type 2 diabetes (T2D). This study aimed to elucidate the role of glucagon in peripheral nerve function in patients with T2D with different body mass indices (BMIs).
Methods: We consecutively enrolled 174 individuals with T2D and obesity (T2D/OB, BMI ≥ 28 kg/m), and 480 individuals with T2D and nonobesity (T2D/non-OB, BMI < 28 kg/m), all of whom underwent oral glucose tolerance tests to determine the area under the curve for glucagon (AUC).

Mitochondrial quality control is crucial for the homeostasis of the mitochondrial network. The balance between mitophagy and biogenesis is needed to reduce cerebral ischemia-induced cell death. Ischemic preconditioning (IPC) represents an adaptation mechanism of CNS that increases tolerance to lethal cerebral ischemia.

Metabolic-associated fatty liver disease (MAFLD) has emerged as a leading chronic liver disease. This condition is characterized by an abnormal accumulation of fat within liver and can progress from simple steatosis to more severe stages involving chronic inflammation and oxidative stress. In this study, we investigated the potential therapeutic effects and underlying mechanism of novel bioactive peptides (EWYF and EWFY) on Western diet-induced MAFLD in C57BL/6J mice.

Summary: A 17-year-old girl presented with recurrent attacks of acute pancreatitis, associated with severe hyperglycemia and hypertriglyceridemia, despite being on intensive insulin therapy for the last 10 years. She had severe acanthosis nigricans, generalized loss of subcutaneous fat and prominent veins over extremities. The serum levels of glucose and triglyceride did not reduce significantly, even with maximally tolerated doses of metformin (2 g), pioglitazone (45 mg) and fenofibrate (160 mg), not uncommonly seen in poor rural families in West Bengal, India.
