Unveiling the Detrimental Effect of Glipizide on Structure and Function of Catalase: Spectroscopic, Thermodynamics and Simulation Studies.

Free radicals, products of oxidative processes, induce cellular damage linked to diseases like Parkinson's and diabetes due to increased reactive oxygen species (ROS) levels. Catalase, crucial for scavenging ROS, emerges as a therapeutic agent against ailments including atherosclerosis and tumor progression. Its primary function involves breaking down hydrogen peroxide into water and oxygen.

Mechanisms of inhibition of advanced glycation end-products (AGEs) and α-glucosidase by Heliotropium bacciferum: Spectroscopic and molecular docking analysis.

Diabetes mellitus is characterized by hyperglycemia that makes insulin more prone to glycation and form advanced glycation end products (AGEs). Here, we report the effect of glyoxal (GO) on the formation of AGEs using human insulin as model protein and their structural modifications. The present investigation also reports the anti-AGE potential of Heliotropium bacciferum (Leaf) extracts.

Genetic Variants of , , , , and Genes Are Associated with Prediabetes Susceptibility and Inflammatory Markers in the Saudi Arabian Population.

Prediabetes is a reversible, intermediate stage of type 2 diabetes mellitus (T2DM). Lifestyle changes that include healthy diet and exercise can substantially reduce progression to T2DM. The present study explored the association of 37 T2DM- and obesity-linked single nucleotide polymorphisms (SNPs) with prediabetes risk in a homogenous Saudi Arabian population.

Agitation does not induce fibrillation in reduced hen egg-white lysozyme at physiological temperature and pH.

Several proteins and peptides tend to form an amyloid fibril, causing a range of unrelated diseases, from neurodegenerative to certain types of cancer. In the native state, these proteins are folded and soluble. However, these proteins acquired β-sheet amyloid fibril due to unfolding and aggregation.

Elucidating the binding and inhibitory potential of p-coumaric acid against amyloid fibrillation and their cytotoxicity: Biophysical and docking analysis.

P-Coumaric acid (p-CA) is a plant metabolite with anti-inflammatory and antioxidant effects. Due to its therapeutic potential, p-CA has attracted much attention from the scientific community lately. Oxidative stress, amyloid formation, and impaired proteasomal degradation are hallmarks of neurodegenerative diseases like Alzheimer's (AD) and are targets for developing therapeutics against such conditions.

Expression, purification, and biophysical characterization of recombinant MERS-CoV main (M) protease.

MERS-CoV main protease (M) is essential for the maturation of the coronavirus; therefore, considered a potential drug target. Detailed conformational information is essential to developing antiviral therapeutics. However, the conformation of MERS-CoV M under different conditions is poorly characterized.

Associations of zinc-α-2-glycoprotein with metabolic syndrome and its components among adult Arabs.

Epidemiological studies suggest that the Zinc-α-2-glycoprotein (ZAG) plays significant physiological roles. In this study we investigate whether ZAG could be considered as a clinical biomarker in the diagnosis and prognosis of metabolic syndrome (MetS) in Saudi population. As such insights urgently required for management of MetS.

Favorable Changes in Fasting Glucose in a 6-month Self-Monitored Lifestyle Modification Programme Inversely Affects Spexin Levels in Females with Prediabetes.

Spexin (SPX) is a novel peptide thought to have a role in various metabolic regulations. Given its presumed body-weight regulatory functions, we aimed to determine whether lifestyle intervention programs on weight loss and fasting glucose (FG) improvement among people with impaired glucose regulation also alter levels of circulating SPX. A total of 160 Saudi adult males and females with prediabetes were randomly selected from a larger cohort (N = 294) who underwent a 6-month lifestyle modification program to improve their glycemic status.

Circulating spexin levels are influenced by the presence or absence of gestational diabetes.

The study aimed to determine whether circulating spexin (SPX) is modified during the course of pregnancy and whether it is affected by the presence of glucose intolerance, i.e., Gestational Diabetes Mellitus (GDM).

Synaptosomal Protein of 25 kDa (Snap25) Polymorphisms Associated with Glycemic Parameters in Type 2 Diabetes Patients.

A possible role of Snap25 polymorphisms in type 2 diabetes mellitus (T2DM) was evaluated by analyzing three SNPs within intron 1 in a region known to affect the gene expression in vitro. Genomic DNA from 1019 Saudi individuals (489 confirmed T2DM and 530 controls) was genotyped for SNPs rs363039, rs363043, and rs363050 in Snap25 using the TaqMan Genotyping Assay. Significantly higher levels of fasting glucose and HbA1c were detected in T2DM patients carrying the rs363050 (AG/GG) genotypes compared to the (AA) genotype (f = 4.

Association between promoter region genetic variants of PTH SNPs and serum 25(OH)-vitamin D level.

Parathyroid hormone (PTH) plays a crucial role in calcium metabolism and skeletal development via altering vitamin D level. Besides, hypersecretion of PTH is implicated in the etiology of osteoporosis. In this study, we analyzed association between promoter region sequence variants of PTH gene and circulating 25-hydroxy-vitamin D (25(OH)D) level.

Association of Type 2 Diabetes Mellitus related SNP genotypes with altered serum adipokine levels and metabolic syndrome phenotypes.

The pathogenesis of T2DM involves secretion of several pro-inflammatory molecules by the dramatically increased adipocytes, both by number and size, and associated macrophages of adipose tissue. Since T2DM is usually preceded by obesity and chronic systemic inflammation, the objective of this study was to explore for any association between genetic variants of previously established 36 T2DM-associated SNPs and altered serum adipocytokine levels and metabolic syndrome phenotypes. Study consisted of 566 subjects (284 males and 282 females) of whom 147 were T2DM patients and 419 healthy controls.

Association between type 2 diabetes mellitus-related SNP variants and obesity traits in a Saudi population.

Obesity, commonly measured as body mass index (BMI), has been on a rapid rise around the world and is an underlying cause of several chronic non-communicable diseases, including type 2 diabetes mellitus (T2DM). In addition to the environmental factors, genetic factors may also contribute to the ongoing obesity epidemic in Saudi Arabia. This study investigated the association between variants of 36 previously established T2DM SNPs and obesity phenotypes in a population of Saudi subjects.

Assessing the contribution of 38 genetic loci to the risk of type 2 diabetes in the Saudi Arabian Population.

Background: Previous genome-wide association studies have identified multiple type 2 diabetes (T2D) genetic risk loci in many populations. However, the contribution of these loci to T2D in the Middle Eastern populations with high T2D prevalence is unknown.

Methods: Here, we investigated the association of 38 T2D risk loci in the Saudi Arabian population (1166 patients with T2D and 1235 healthy controls), which has one of the world's highest prevalence of T2D.

Metabolic syndrome biomarkers and early breast cancer in Saudi women: evidence for the presence of a systemic stress response and/or a pre-existing metabolic syndrome-related neoplasia risk?

Background: Obesity has been linked to many adverse health consequences, including breast cancer. This study aims to determine adipocytokine and other biological changes in recently diagnosed breast cancer patients before therapy is started.

Methods: A total of 109 female Saudi subjects [56 newly diagnosed, treatment-naïve, histologically-confirmed breast cancer cases and 53 age- and BMI-matched controls] were enrolled in this study.
