Schizophrenia is one of the most debilitating mental illnesses affecting any age group. The mechanism and etiology of schizophrenia are extremely complex and multiple signaling pathways recruit genes implicated in the etiology of this disease. While the role of Wnt/β-catenin signaling in this disorder has been verified, the impact of long noncoding RNAs (lncRNAs) associated with this pathway has not been studied in schizophrenia.

Extramedullary plasmacytomas (EMP) are uncommon solitary tumors composed of neoplastic plasma cells occurring outside the bone. These lesions are of clinical significance due to their potential progression to multiple myeloma (MM), a more systemic and serious plasma cell malignancy. Although EMPs primarily arise in the head and neck region, cases involving the oral cavity are particularly rare.

Internal root resorption (IRR) is a complex and often asymptomatic dental condition that can severely compromise tooth vitality and function. This case report presents the successful management of a perforated large IRR lesion in a 49-year-old female using an ultraconservative approach involving partial pulpectomy (PP) using calcium-enriched mixture (CEM) cement. The patient, initially presenting with an asymptomatic resorptive lesion in her left first premolar, underwent ultraconservative PP following diagnosis via conventional radiography and cone beam computed tomography.

Lactulose Versus Naloxone for Opioid-Induced Constipation in Intensive Care.

Turk J Pharm Sci

January 2025

Shahid Beheshti University of Medical Sciences Faculty of Medicine, Toxicological Research Center, Excellence Center and Department of Clinical Toxicology, Tehran, Iran.

Objectives: Constipation caused by opioid-induced constipation (OIC) is prevalent among critically poisoned patients and can result in complications that prolong hospitalization and, in rare cases, cause bowel perforatio This research aimed to evaluate the safety and efficacy of lactulose and naloxone in the treatment of OIC in the intensive care unit for poisoning.

Materials And Methods: This was a randomized, double-blind, clinical trial of patients with opioid poisoning who experienced constipation for 14 months. Patients were divided into two groups: one receiving lactulose (30 cc daily) and the other receiving naloxone (8 mg three times a day).

Dual Checkpoint Inhibition in M2 Macrophages via Anti-PD-L1 and siRNA-Loaded M1-Exosomes: Enhancing Tumor Immunity through RNA-Targeting Strategies.

Eur J Pharmacol

January 2025

Department of Immunology, School of Medicine, Tehran University of Medical Sciences, Tehran, Iran; Research Center for Immunodeficiencies, Children's Medical Center, Tehran University of Medical Sciences, Tehran, Iran; Network of Immunity in Infection, Malignancy and Autoimmunity (NIIMA), Universal Scientific Education Research Network (USERN), Tehran, Iran. Electronic address:

The interaction between a cluster of differentiation 47 (CD47) on cancer cells and signal regulatory protein alpha (SIRPα) on macrophages is thought to hinder macrophage phagocytic activity, which can be blocked by combining siRNAs targeting SIRPα (siSIRPα) with simultaneous involvement of activating receptors like FcRs (Fc receptors) anti-programmed death-ligand 1 (anti-PD-L1). For this study, M1 macrophage-derived exosomes were used to deliver the siRNAs, isolated from lipopolysaccharide (LPS)-stimulated RAW264.7 cells and electroporated with siSIRPα.

Department of Internal Medicine, University of Texas Southwestern Medical Center, Dallas, TX. Electronic address:

Hepatocellular carcinoma (HCC) is a major concern for public health. Fatty liver disease, related to alcohol misuse or metabolic syndrome, has become the leading cause of chronic liver disease and HCC. The strong association between type 2 diabetes mellitus and HCC can be partly attributed to the development of metabolic dysfunction associated steatotic liver disease (MASLD).

Cell Mol Biol (Noisy-le-grand)

January 2025

Department of Physiology, Faculty of Medicine, Tehran Medical Sciences, Islamic Azad University, Tehran, Iran.

Article Synopsis
  • Intrauterine exposure to methamphetamine (METH) during pregnancy negatively impacts testicular development in offspring, leading to apoptosis in spermatids.
  • Research focused on proteins involved in sperm growth pathways, particularly TSSK and RIPK2, showing significant changes in their expression levels due to METH exposure.
  • Findings indicated that METH exposure resulted in decreased TSSK expression, increased RIPK2 expression, thinner germ layers, more inflammatory cells, and a reduction in the thickness of seminiferous tubules in rat testes.

The integration of artificial intelligence (AI) into dental imaging has led to significant advancements, particularly in the analysis of panoramic radiographs, also known as orthopantomograms (OPGs). One emerging application of AI is in determining gender from these radiographs, a task traditionally performed by forensic experts using manual methods. This systematic review and meta-analysis aim to evaluate the accuracy of AI algorithms in gender determination using OPGs, focusing on the reliability and potential clinical and forensic applications of these technologies.

IL-27 is structurally an immune-enhancing and pleiotropic two-chain cytokine associated with IL-12 and IL-6 families. IL-27 contains two subunits, namely IL-27p28 and EBI3. A heterodimer receptor of IL-27, composed of IL27Rα (WSX1) and IL6ST (gp130) chains, mediates the IL-27 function following the activation of STAT1 and STAT3 signaling pathways.
