Orphan G Protein-Coupled Receptors: A Novel Research Frontier in Autism and Associated Disorders.

G-protein coupled receptors (GPCRs) are a diverse group of membrane proteins crucial for transmitting extracellular signals into cells, regulating numerous neurological processes. Among GPCRs, orphan receptors, whose natural ligands and functions remain unidentified, have garnered increasing research attention. Olfactory receptors (ORs), the most diverse GPCR family, are widely expressed in the central nervous system (CNS) and are implicated in autism spectrum disorder (ASD) and related behavioral and psychiatric conditions.

Evaluating the discriminatory capacity of traditional and novel anthropometric indices in cardiovascular disease risk factors, considering sex differences.

Objective: Cardiovascular disease (CVD) rates are rising rapidly worldwide, making it crucial to implement simple and effective screening measures to identify individuals at increased risk for CVD risk factors. This study aims to examine the relationship between innovative anthropometric indices and the occurrence of cardiovascular risk factors among the population of Mashhad, located in northeastern Iran, over a ten-year follow-up period.

Methods: In this cohort study, a total of 9704 individuals aged 35-65 years were recruited at baseline, with 7560 individuals completing the study.

Regulatory effects of statins on CCL2/CCR2 axis in cardiovascular diseases: new insight into pleiotropic effects of statins.

Background: HMG-CoA reductase inhibitors are well-known medications in the treatment of cardiovascular disorders due to their pleiotropic and lipid-lowering properties. Herein, we reviewed the effects of statins on the CCL2/CCR2 axis.

Method: Scopus and Pubmed databases were systematically searched using the following keywords:" Hydroxymethylglutaryl CoA Reductase Inhibitors"," HMG-CoA Reductase Inhibitors"," Statins", "CCL2, Chemokine", "Monocyte Chemoattractant Protein-1" and "Chemokine (C-C Motif) Ligand 2".

DNA Methylation in Autism Spectrum Disorders: Biomarker or Pharmacological Target?

Autism spectrum disorder (ASD) is a group of heterogeneous neurodevelopmental disabilities with persistent impairments in cognition, communication, and social behavior. Although environmental factors play a role in ASD etiopathogenesis, a growing body of evidence indicates that ASD is highly inherited. In the last two decades, the dramatic rise in the prevalence of ASD has interested researchers to explore the etiologic role of epigenetic marking and incredibly abnormal DNA methylation.

Targeting the CCL2-CCR2 signaling pathway: potential implications of statins beyond cardiovascular diseases.

Background: The chemokine ligand CCL2 and its cognate receptor CCR2 have been implicated in the pathogenesis of a wide variety of diseases. Hence, the inhibition of the CCL2/CCR2 signaling pathway has been of great attention in recent studies. Among suggested medications, statins known as HMG-COA reductase inhibitors with their pleiotropic effects are widely under investigation.

Prognostic value of primary tumor location in colorectal cancer: an updated meta-analysis.

The clinical, histological, and molecular differences between right-sided colon cancer (RCC) and left-sided colon cancer (RCC) have received considerable attention. Over the past decade, many articles have been published concerning the association between primary tumor location (PTL) of colorectal cancer and survival outcomes. Therefore, there is a growing need for an updated meta-analysis integrating the outcomes of recent studies to determine the prognostic role of right vs left-sidedness of PTL in patients with colorectal cancer.

Serum level and tumor tissue expression of Ribonucleotide-diphosphate Reductase subunit M2 B: a potential biomarker for colorectal cancer.

Background: This study explored the applicability of serum level and tissue expression of Ribonucleotide-diphosphate Reductase subunit M2 B (RRM2B) as reliable biomarkers for colorectal cancer (CRC) progression and metastasis.

Methods And Results: The present descriptive-analytic cohort study was conducted on 50 newly diagnosed CRC patients (stage II, III) and 50 healthy individuals. The new cases had not received any therapeutic intervention and underwent surgery immediately after the initial diagnosis.

Gastrointestinal and hepatic abnormalities in patients with confirmed COVID-19: A systematic review and meta-analysis.

Although not common, gastrointestinal and liver symptoms have reportedly been the initial presentation of coronavirus disease-2019 (COVID-19) in a large group of patients. Therefore, knowing the frequency and characteristics of these manifestations of COVID-19 is important for both clinicians and health policy makers. A systematic review and meta-analysis of the available data on the gastrointestinal and liver manifestations of patients with COVID-19 was performed.
