Unraveling the Exosome-miR-133a Axis: Targeting TGF-β Signaling via WJ-MSC-Derived Exosomes for Anti-Fibrotic Therapy in Liver Fibrosis.

Background: One of the primary drivers of liver fibrosis is the excessive accumulation of ECM, primarily caused by the over-proliferation of HSCs. The activation of HSCs by TGF-β has a critical role in initiating fibrosis. Recent studies have suggested that miRNA-133a significantly regulates the fibrogenesis process, which its downregulation is associated with the fibrosis progression.

Nanocodelivery of 5-Fluorouracil and Curcumin by RGD-Decorated Nanoliposomes Achieves Synergistic Chemotherapy for Breast Cancer.

Comprehensive copy number analysis of spinal muscular atrophy among the Iranian population.

Copy number variations in the SMN1 gene on chromosome 5 are the primary cause of Spinal Muscular Atrophy (SMA) disease, characterized by muscle weakness and degeneration due to impaired alpha motor neurons in the spinal cord. To obtain a comprehensive molecular understanding of the SMA, including carriers, silent carriers, and patients in the Iranian population, we analyzed data from 5224 individuals referred to Kariminejad - Najmabadi Pathology & Genetics Center, Tehran, Iran, between 2006 and 2023 using MLPA and quantitative RT-PCR methods. The carrier frequency of SMA was estimated to be 5.

Comparative Effects of Crocin and Losartan on RAGE, TGF-β, TNF-α Gene Expression and Histopathological Changes of the Liver Tissue in Rats With Diabetes.

Background And Objectives: AGEs, via RAGE, increase the development of hyperglycemia-induced liver damage, and blocking this axis is associated with a reduction in liver disease progression. The goal of this study was to determine how crocin and losartan influenced RAGE, TNF-α and TGF-β gene expression in diabetic rats, as well as histological changes in liver tissue.

Materials And Methods: Diabetes was induced in 40 male Wistar rats using Streptozotocin (50 mg/kg, IP).

Expanding the genotypic and phenotypic spectrum of EAST/SeSAME syndrome: identification of a novel homozygous mutation (c.194 G > A) in KCNJ10 gene.

Introduction: EAST/SeSAME syndrome is an ultra-rare disease characterized by seizures, epilepsy, sensorineural deafness, ataxia, mental retardation, and electrolyte imbalance and arises due to deleterious variants disrupting the function of the KCNJ10 gene. In this study, we investigated the clinical symptoms and genetic cause of the disease in a 10-year-old Iranian girl who presented with neurological, hearing, and renal problems.

Methods: Magnetic resonance imaging (MRI), electroencephalography (EEG), and laboratory tests were performed to evaluate the clinical characteristics of the proband.

Green synthesis of zinc nanoparticles by hydroalcoholic extract of lavender (Lavandula stoechas L.), characterization, and cytotoxic effects on human breast and colon cancer.

Green synthesis is the production of metal nanoparticles (MNPs) with biological agents, including plant extracts; it is environmentally friendly. The study aimed to investigate the cytotoxic effects of zinc nanoparticles (ZnNPs) synthesized by the hydroalcoholic extract of lavender (Lavandula stoechas L.) against MCF7 and HT29 with the approach of identifying the ability of these NPs to produce anticancer drugs.

The emerging role of the microglia triggering receptor expressed on myeloid cells (TREM) 2 in multiple sclerosis.

Background: The chronic inflammatory condition known as multiple sclerosis (MS) causes inflammation and demyelination in the central nervous system (CNS). The activation of multiple cell types, including the CNS's resident immune cells called microglia, is a component of the immunological response in MS. Recently, the triggering receptor expressed on myeloid cells (TREM) family has emerged as a crucial player in modulating microglial function and subsequent neuroinflammation.

Anti-biofilm activity of carvacrol-thymoquinone nanocarriers on vulvovaginal candidiasis isolates.

Given the recurrent nature of vulvovaginal candidiasis (VVC), the restricted availability of effective antifungal agents, and the recent rise in drug resistance, this study sought to assess the antifungal efficacy of carvacrol-thymoquinone delivered via a nanocarrier on Candida isolates obtained from patients with VVC. Isolates were identified using phenotypic and genotypic methods. Nanocarriers were synthesized using the thin-film hydration method.
