Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by high blood sugar levels. It was shown that modulating the activity of α-glucosidase, an enzyme involved in carbohydrate digestion and absorption, can improve blood sugar control and overall metabolic health in individuals with T2DM. As a result, in the current study, a series of imidazole bearing different substituted thioquinolines were designed and synthesized as α-glucosidase inhibitors.

Background And Aim: Epidemiologic studies have shown that type 2 diabetes (T2D) is more prevalent worldwide; therefore, improving glycemic indices to prevent or control T2D is vital. Randomized controlled trials (RCTs) on the effects of pomegranate consumption on glycemic indices have shown inconsistent results. Therefore, we aim to evaluate the impact of pomegranate consumption on fasting blood glucose (FBG), fasting insulin, hemoglobin A1c (HbA1c), and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) in adults.

Endometrial Carcinoma Arising from Adenomyosis (EC-AIA) is an unusual condition, primarily occurring in postmenopausal women. We present a rare case of a 34-year-old woman with EC-AIA, highlighting the diagnostic challenges in distinguishing this malignancy from adenomyosis preoperatively. Conventional imaging methods exhibited limitations, necessitating post-surgery confirmation through comprehensive examinations.

Subtyping irritable bowel syndrome using cluster analysis: a systematic review.

BMC Bioinformatics

December 2023

Research Center for Immunodeficiencies, Children's Medical Center, Tehran University of Medical Sciences, Dr. Qarib St, Keshavarz Blvd, Tehran, 14194, Iran.

Article Synopsis
  • Irritable bowel syndrome (IBS) is a common stomach issue that causes various symptoms, and researchers are trying to understand it better using a method called cluster analysis.
  • In a review of 14 studies, different methods of analysis were used to group IBS patients based on their symptoms and other factors, revealing that there are different subgroups among these patients.
  • The studies showed that many IBS patients had mild symptoms and a decent quality of life, but they also had unique characteristics like changes in gut bacteria and sensitivity in their rectal area.

Lipid accumulation, inflammation, and oxidative stress are the most important causes of muscle insulin resistance. The aim of this study was to investigate the single and combined treatment effects of metformin (MET) and morin (MOR) on lipid accumulation, inflammation, and oxidative stress in the skeletal muscle of mice fed a high-fat diet. The mice were supplemented with MET (230 mg/kg diet), MOR (100 mg/kg diet), and MET + MOR for 9 weeks.

A Brief Review of Low-Level Light Therapy in Depression Disorder.

J Lasers Med Sci

November 2023

INFN-Laboratori Nazionali di Frascati, Via E. Fermi 54, 00044 Frascati, Italy.

Low-level laser therapy (LLLT), also called Photobiomodulation, has gained widespread acceptance as a mainstream modality, particularly in the form of photobiostimulation (PBM). Here in our review, we aim to present the application of LLLT to help with depression, explore potential action mechanisms and pathways, discuss existing limitations, and address the challenges associated with its clinical implementation. In biological systems, the visible light with a wavelength range of 400-700 nm activates photoreceptors involved in vision and circadian rhythm regulation.
