have been widely used as spice or traditional medicine in East Asia, commonly known as Thai ginger. In the present study, seven major phenylpropanoids, (±)-1'-hydoxychavicol acetate (; HCA), (1')-1'-acetoxychavicol acetate (; ACA), (1')-1'-acetoxyeugenol acetate (; AEA), eugenyl acetate (), --coumaraldehyde (), --acetoxycinnamyl alcohol (), and --coumaryl diacetate (), were isolated from the 95% EtOH and hot water extracts of the rhizomes of . by chromatographic method. Phenylpropanoids - were evaluated for glucose-stimulated insulin secretion (GSIS) effect and α-glucosidase inhibitory activity. Phenylpropanoids - increase GSIS effect without cytotoxicity in rat INS-1 pancreatic β-cells. In addition, INS-1 cells were treated with AEA () to determine a plausible mechanism of β-cell function and insulin secretion through determining the activation of insulin receptor substrate-2 (IRS-2), phosphatidylinositol 3-kinase (PI3K), Akt, and pancreatic and duodenal homeobox-1 (PDX-1). Upon treatment with AEA (), INS-1 cells showed an increase in these protein expressions. Meanwhile, AEA () exhibited α-glucosidase inhibitory activity. On the basis of the above findings, we suggest AEA () as a potential antidiabetic agent.

Purpose: Imeglimin is a novel oral antidiabetic agent that improves glucose tolerance. This study aimed to investigate the efficacy of combining imeglimin with dipeptidyl peptidase-4 inhibitor (DPP-4i), the most frequently prescribed first-line treatment for patients with type 2 diabetes (T2D) in Japan, to improve glycemic control.
Patients And Methods: Eleven patients with T2D treated with DPP-4i alone (6.

Aims: To compare the probability of achieving diabetes remission in individuals with different phenotypes of insulin sensitivity, insulin secretion, and beta cell function and further detect the effects of diet, exercise, and lifestyle education intervention on these indexes.
Methods: Three-hundred and one participants who had glycated haemoglobin (HbA1c) data at baseline and after intervention were included for this post hoc analysis. We used the multi-way analysis of variance to assess the differences between the diabetes remission and non-remission groups or between intervention groups in changes of the indexes of insulin sensitivity, insulin secretion, and beta cell function.

Aim: To achieve glucose-activated transcriptional regulation of insulin analogue in skeletal muscle of T1D mice, thereby controlling blood glucose levels and preventing or mitigating diabetes-related complications.
Materials And Methods: We developed the GANIT (Glucose-Activated NFAT-regulated INSA-F Transcription) system, an innovative platform building upon the previously established intramuscular plasmid DNA (pDNA) delivery and expression system. In the GANIT system, skeletal muscle cells are genetically engineered to endogenously produce the insulin analogue INSA-F (Insulin Aspart with Furin cleavage sites).

Diabetes mellitus, particularly type 2 diabetes mellitus (T2DM), is a pervasive chronic disease that affects millions of people worldwide. It predisposes individuals to a range of severe microvascular and macrovascular complications, which drastically impact the patient's quality of life and increase mortality rates owing to various comorbidities. This extensive review explores the intricate pathophysiology underlying diabetic complications, focusing on key mechanisms, such as atherosclerosis, insulin resistance, chronic inflammation, and endothelial dysfunction.

Objective: In the Diabetes Virus Detection and Intervention trial, antiviral treatment with pleconaril and ribavirin decreased the decline, compared with placebo, in endogenous C-peptide 1 year after diagnosis of type 1 diabetes (T1D) in children and adolescents. This article reports the results 2 and 3 years after diagnosis.
Research Design And Methods: This was a multicenter, randomized, placebo-controlled (1:1) trial of 96 children and adolescents aged 6-15.
