Iron and Other Metal Ions in Human Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
Iron, copper, zinc, and calcium orchestrate cellular function through distinct yet cooperative mechanisms: redox‐active iron and copper cycle between oxidation states to act as Fenton catalysts and electron carriers in oxidative phosphorylation (OXPHOS); redox‐inert zinc serves as a structural component of zinc‐finger proteins and a catalytic cofactor ...

Batesian mimics influence mimicry ring evolution

, 2003
Mathematical models of mimicry typically involve artificial prey species with fixed colorations or appearances; this enables a comparison of predation rates to demonstrate the level of protection a mimic might be afforded.

Testicular Biopsies in Adolescent and Adult Andrological Patients: The EAA Clinical Guidelines

Andrology, Volume 14, Issue 7, Page 1906-1928, October 2026.
ABSTRACT Background Histological evaluation of testicular tissue is central to the assessment of infertile men, particularly those at an increased risk of testicular germ cell tumors (TGCT). Traditionally, testicular biopsies have been used primarily for diagnostic purposes, such as the detection of germ cell neoplasia in situ (GCNIS). With advances in

DiI Analysis of Cell Migration during Mullerian Duct Regression

, 1995
In most male vertebrates, the Mullerian ducts, which are the embryonic oviducts, regress completely during embryogenesis or shortly thereafter. Mullerian duct regression is caused by the testicular hormone Mullerian inhibiting substance.

Divergent effects of hyperandrogenemia on the female reproductive neuroendocrine axis under different physiological conditions

Journal of Neuroendocrinology, Volume 38, Issue 10, October 2026.
Abstract The hypothalamic–pituitary–gonadal (HPG) axis coordinates reproductive function and incorporates gonadal sex steroid feedback to regulate gonadotropin secretion in a homeostatic manner. In females, ovarian estrogens and progestins act as the primary negative feedback signals to suppress luteinizing hormone (LH) release, whereas in males ...

Ethanolamine plasmalogens increase luteinising hormone pulsatility and are associated with GPR61 expression in bovine gonadotrophin‐releasing hormone neurons

Journal of Neuroendocrinology, Volume 38, Issue 10, October 2026.
Ethanolamine plasmalogens increased LH pulse frequency. GPR61 was expressed in GnRH neurons and gonadotrophs, suggesting a role in neuroendocrine regulation. Ethanolamine plasmalogens (EPls), but not choline plasmalogens (CPls), may act via GPR61 expressed in GnRH neurons in the preoptic area and in anterior pituitary gonadotrophs.

Functional redundancy of TGF-beta family type receptors and receptor-smads in mediating anti-Mullerian hormone-induced Mullerian duct regression in the mouse [PDF]

, 2008
Amniotes, regardless of genetic sex, develop two sets of genital ducts: the Wolffian and Mulerian ducts. For normal sexual development to occur, one duct must differentiate into its corresponding organs, and the other must regress.
