To determine the occurrence of microsporidiosis in domestic pigeons in Iran, privately-owned pigeons presenting weight loss and diarrhea were tested through molecular and histopathological methods. Multiplex-PCR findings showed 57%, 30%, and 14% positivity for , , and mixed infection in the fecal samples, respectively. A novel genotype, named IrnEb1, falling into zoonotic group 1 of , and a novel genotype of , named Irn2E, clustering as a sister taxon to genotype 2B were identified in pigeons for the first time using Sanger sequencing and phylogenetic analyses.

(miRNAs) are a class of small non-coding RNAs with a length of 21-25 nucleotides and play an essential role in the regulation of cancer initiation, development and progression. Breast cancer (BC) is the most commonly detected malignancy in women and one of the leading causes of death worldwide. In this study, the effects of transfection of microRNA-451a-5p and miR-34a-5p (tumor suppressors), individually and in combination on apoptosis, proliferation and migration of breast cancer cells were investigated.

Article Synopsis
  • Effective targeting using nano drug delivery systems (NDDS) helps deliver medications directly into cancer cells, improving treatment efficiency by overcoming cellular defenses.
  • The study developed a dual-responsive nanoparticle system loaded with the chemotherapy drug DTX that activates specifically in the tumor environment, leading to a significant release of the drug.
  • In tests, the new formulation showed 5 times greater cytotoxicity compared to free DTX, effectively inhibiting tumor growth in mice with lower doses, indicating a promising advancement in cancer treatment strategies.

Objective Of The Research: Air pollution is a universal issue and has significant deleterious effects on both human health and also environment. The important indicators of air pollution include ozone (O3), particulate matter (PM), nitrogen dioxide (NO2), and sulfur dioxide (SO2). This research aims to investigate the impacts of ambient air pollution (AAP), SO2, and O3 on oxidative stress parameters, liver tissue histopathology, and expression of some carcinogenesis-related genes in the hepatic tissue of rats.

Article Synopsis
  • The study investigates the clinical, histopathological, and molecular features of skin papillomas in small ruminants (sheep and goats) in Iran.
  • Researchers collected samples from 19 animals with papillomatosis lesions of varying sizes, primarily on the limbs, and used histopathological and molecular techniques for analysis.
  • Findings revealed distinct pathological characteristics and confirmed the presence of papillomavirus in all samples, highlighting the importance of differentiating these lesions from other viral skin diseases.
