Continuous darkness is associated with improved growth performance during a high‐temperature period and sex‐specific modulation of early gonadal development in juvenile yellowtail (Seriola quinqueradiata)

Journal of Fish Biology, EarlyView.
Abstract Selective breeding of yellowtail (Seriola quinqueradiata) is expanding in Japan, increasing the demand for practical reproductive control tools in commercial aquaculture to reduce genetic risks from escapees. Slowing early gonadal development through environmental manipulation may support future sterilization strategies, particularly when ...

Anti-fertility effect of three inorganic salts against land snail, Massylaea vermiculata, (O.F. Müller1774) and their field efficiency

Journal of Basic and Applied Zoology, 2021
Background The ovotestis gland (the hermaphrodite gland) is a reproductive system organ that affects fertility of land snails. Thus, the present study was conducted to evaluate the effect of three inorganic salts (sodium carbonate, sodium benzoate, and ...

Total synthesis and structural characterization of a novel protein scaffold from the snail Biomphalaria glabrata

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Disulfide‐rich miniproteins constitute compact and highly stable scaffolds of growing interest for molecular and structural engineering. Schistosomins are ~80‐residue proteins conserved across gastropods that form a long‐standing orphan family whose structure and biological roles have remained unknown.

Crossed ectopia of ovotestis in a case of true hermaphroditism

Journal of Pediatric Surgery, 1996
True hermaphroditism is a rare form of intersex disorder. The authors report a case of true hermaphroditism with crossed ectopia of an ovotestis from the left to the right scrotum. The karyotype of the patient was 46,XX, without mosaicism. The majority of the ovotestis was comprised of testicular tissue.

Modern competency‐based teaching of human sexual development

Anatomical Sciences Education, Volume 19, Issue 7, Page 1086-1096, July 2026.
Abstract Embryology is an integral part of anatomy and a key subject in basic medical education. The development of the sexual tract, which is closely associated with the formation of the urinary tract and the organs of continence, is particularly complex and relevant for many medical disciplines.

True hermaphroditism in a wistar rat

Brazilian Journal of Veterinary Pathology, 2009
A rare case of true hermaphroditism was observed in a 9-week-old presumed female Wistar rat. This rat did not reveal any untoward clinical signs, food consumption, body weight gain and changes in haemato-biochemical parameters.

Biochemical and histopathological responses of Biomphalaria alexandrina to RIPEX (plant growth regulator)

Beni-Suef University Journal of Basic and Applied Sciences, 2023
Background Plant growth regulators are widely used in agriculture for increasing the growth and ripening of plants, but they endanger the aquatic ecosystem. The current study assessed the effect of sublethal exposure to RIPEX 48% EC concentrations (8 and

Genotype–Phenotype Correlations in Klinefelter and Turner Syndrome: A Decade of Sex Chromosome Aneuploidy Data From a Single Academic Medical Center

Molecular Genetics &Genomic Medicine, Volume 14, Issue 1, January 2026.
To understand the relationship between genotype and phenotype in sex chromosome aneuploidies, retrospective cytogenetic and clinical data was collected for Klinefelter Syndrome (n = 57) and Turner Syndrome (n = 92) cases from a single academic medical center from 2013 to 2022. The cohorts were divided into subcategories based on the genotype.
