Molecular Detection of Type 1 Fimbriae-Encoding Gene (fimH) in Uropathogenic Escherichia coli Strains Isolated from Outpatients with Urinary Tract Infection [PDF]

Journal of Fasa University of Medical Sciences, 2016
Background & Objective: Urinary Tract Infection (UTI) is one of the most common infections in all age groups. The majority of these infections are caused by Uropathogenic Escherichia coli (UPEC) strains. Colonization, attachment to uroepithelium, and the

Sex Determination in Sponges

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.
ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

Pharmacologic MRI Brain Imaging Studies of Serotonin 5‐HT1 Receptor Agonists in Awake Mice

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT Serotonin (5‐hydroxytryptamine, 5‐HT) type‐1 G protein‐coupled receptors are expressed throughout the central nervous system. 5‐HT1AR activation is the putative mechanism of approved drugs for generalized anxiety disorder and major depressive disorder and is being studied in the treatment of autism and neurological disorders.
