Glucagon-like Peptide-1 Receptor Agonists
Type 2 diabetes mellitus (T2DM) is a heterogeneous, chronic, progressive metabolic disease accounting for 90–95% of all diabetes. Glucagon-like peptide-1 (GLP-1) receptor agonists are a new class of antihyperglycemic drugs that enhance appropriate pancreatic β-cell secretion, pancreatic α-cell (glucagon) suppression, decrease liver glucose production, increase satiety through their action on the central nervous system, slow gastric emptying time, and increase insulin action on peripheral tissue. They are effective in the management of type 2 diabetes mellitus and have a favorable effect on weight loss.

Proprotein Convertase Subtilisin/Kexin Type 9 and Atherosclerosis
Proprotein convertase subtilisin/kexin type 9 (PCSK9) is the last discovered member of the family of proprotein convertases (PCs), mainly synthetized in hepatic cells. This serine protease plays a pivotal role in the reduction of the number of low-density lipoprotein receptors (LDLRs) on the surface of hepatocytes, which leads to an increase in the level of cholesterol in the blood. The main anti-atherosclerotic effect of PCSK9 inhibitors results from their lipid-lowering efficiency.

Metformin and Insulin Resistance
Metformin is the most commonly used treatment to increase insulin sensitivity in insulin-resistant (IR) conditions such as diabetes, prediabetes, polycystic ovary syndrome, and obesity. This study explores the underlying mechanisms of the metformin's effect on IR mainly through the changes in the glucose transporter 4 (GLUT4)-mediated glucose transport.

Hypoglycemia, Vascular Disease and Cognitive Dysfunction in Diabetes
Hypoglycemia has been recognized as a risk factor for diabetic vascular complications and cognitive decline. In this work, gene networks of hypoglycemia and cardiovascular disease, diabetic retinopathy, diabetic nephropathy, diabetic neuropathy, cognitive decline, and Alzheimer’s disease were reconstructed. The gene network of hypoglycemia included 141 genes and 2467 interactions. Hypoglycemia-related genes were overrepresented in the reconstructed gene networks of diabetic complications and comorbidity. Some GO biological processes, including glucose homeostasis, nitric oxide biosynthesis, smooth muscle cell proliferation, ERK1 and ERK2 cascade, were overrepresented in all reconstructed networks.

Metabolic Obesity in People with Normal Body Weight
The term Metabolic Obesity in People with Normal Body Weight (MONW) is used to describe people who, despite having a healthy body weight - usually defined by the body index (BMI), and more and more often also the percentage of adipose tissue - show metabolic disorders characteristic of obese people.

Folates
Folates are crucial to life, as a component and catalyst for essential biochemical reactions, particularly and especially via their central role in the metabolism of nucleotides for DNA synthesis and methylation processes involved in imprinting and epigenesis.

Diagnostic Approaches for Epstein–Barr Virus
Epstein–Barr virus (EBV) is the causative agent of many diseases including infectious mononucleosis (IM), and it is associated with different subtypes of lymphoma, sarcoma and carcinoma such as Hodgkin’s lymphoma, non-Hodgkin’s lymphoma, nasopharyngeal carcinoma, and gastric carcinoma. With the advent of improved laboratory tests for EBV, a timelier and accurate diagnosis could be made to aid better prognosis and effective treatment. For histopathological lesions, the in situ hybridization (ISH) of EBV-encoded RNA (EBER) in biopsy tissues remains the gold standard for detecting EBV.

COVID-19 and the Endocrine System
SARS-CoV-2 is a member of the Coronaviridae family, a group of enveloped, positive-sense, single-stranded RNA viruses. Many extrapulmonary manifestations of the coronavirus disease 2019 (COVID-19) have been reported involving the cardiovascular, renal, gastrointestinal and urinary systems. These widespread manifestations are attributed to the presence of the ACE2 (Angiotensin converting enzyme 2) receptor in these tissues, which is postulated to be at the center of the pathogenesis of COVID-19. Similarly, expression of the ACE2 receptor has also been reported in various endocrine tissues including the hypothalamus, pituitary, thyroid, gonads, and pancreatic islets. Therefore, it is imperative to understand the way COVID-19 can alter the function of these tissues and cause pathology, especially considering the close interplay between various endocrine systems as part of the RAAS (renin–angiotensin–aldosterone system) pathway and the central role of ACE2 in this pathway.

Sex/Gender Differences in Uses and Effects of Metformin
Metformin (MTF) occupies a major and fundamental position in the therapeutic management of type 2 diabetes mellitus (T2DM). Gender differences in some effects and actions of MTF have been reported. Women are usually prescribed lower MTF doses compared to men and report more gastrointestinal side effects. The incidence of cardiovascular events in women on MTF has been found to be lower to that of men on MTF.

Definition of Hypertension and Establishment of Treatment Targets
Hypertension is the most frequent chronic and non-communicable disease all over the world, with about 1.5 billion affected individuals worldwide. Its impact is currently growing, particularly in low-income countries. Even in high-income countries, hypertension remains largely underdiagnosed and undertreated, with consequent low rates of blood pressure (BP) control.
