Perinatal Exposure to the Neonicotinoid Thiacloprid Impacts Transcription of Neuroplasticity and Neuroendocrine Markers in Mice but Not in the Zebrafish Model

Journal of Applied Toxicology, EarlyView.
ABSTRACT Neonicotinoids are widely used insecticides in agriculture, aquaculture, pet care, and urban pest control. Initially developed to selectively target the insect cholinergic system, their extensive use has raised concerns about adverse effects on nontarget vertebrates.

Effect of fish size and seasonal changes on gonadal steroid hormones in pike brood stocks (Esox lucius)

یافته‌های نوین در علوم زیستی, 2018
Sex steroid hormones play important roles in many physiological processes, particularly in the reproduction of teleostei. Therefore, study of steroid hormones in fish is one of the important indicators of reproductive biology.

Endocrinology of Transgender Medicine [PDF]

, 2018
Gender-affirming treatment of transgender people requires a multidisciplinary approach in which endocrinologists play a crucial role. The aim of this paper is to review recent data on hormonal treatment of this population and its effect on physical ...

Population Variation in Steroid Hormone‐Related Gene Expression and Sexually Dimorphic Communication in the Electric Fish Apteronotus albifrons

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The development and maintenance of sexually dimorphic behavior often depends on gonadal steroids. Interspecific variation in the magnitude of behavioral sex differences may be mediated by differences in steroid action on neural circuits controlling behavior.

The "backdoor pathway" of androgen synthesis in human male sexual development. [PDF]

, 2019
Mammalian sex determination (male versus female) is largely controlled by genes, whereas sex differentiation (development of reproductive structures) is largely controlled by hormones. Work in the 20th century indicated that female external anatomy was a

Elevating Testosterone and Androstenedione Produces Temporary Sex‐Dependent Variation in Japanese Quail (Coturnix japonica) Embryonic Development

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Vertebrate growth rates may respond to maternally supplied steroids, yet injections of individual hormones into avian eggs of different species have produced inconsistent results. This might be because diverse steroids' concentrations are naturally correlated in yolks, injections are not elevating hormones at critical times in development, or ...

Assessment of functional state of the pituitary-gonadal system in fertile women with acute hepatitis A

Acta Biomedica Scientifica, 2014
Liver is a necessary participant of the metabolism of steroid hormones, so dysfunction of pituitary-gonadal system is possible at viral hepatitis A. We assessed functional state of pituitary-gonadal part of neuroendocrinal regulation system in fertile ...

The Evolving Landscape of Immunotoxicity: Charting Mechanisms and Future Strategies for Immune Checkpoint Inhibitor Adverse Events

Med Research, EarlyView.
ABSTRACT The use of immune checkpoint inhibitors (ICIs) has significantly improved the efficacy of cancer therapy, but their associated immune‐related adverse events (irAEs) can severely compromise treatment safety. This review systematically summarizes the core mechanisms underlying irAEs, which include multi‐organ damage resulting from T‐cell ...
