Andrology, Volume 14, Issue 1, Page 196-209, January 2026.Abstract Background Thyroid hormones play a key role in testicular development, particularly in the regulation of Sertoli cell proliferation and differentiation. While congenital hypothyroidism is common and treatable, the effects of thyroid hormone insufficiency on early testicular development during the neonatal period remain unclear. Objectives This

Andrology, Volume 14, Issue 1, Page 10-24, January 2026.ABSTRACT Background Numerous publications have questioned the lack of analytical reliability and clinical relevance of sperm morphology assessment for infertility workup and before use of assisted reproductive techniques (ART). There is a huge variability in the performance and interpretation of this test.

Acta Physiologica, Volume 242, Issue 1, January 2026.ABSTRACT Aim The circadian clock in the suprachiasmatic nuclei of the hypothalamus (SCN) is resistant to glucocorticoids (GC) in adults but responds to dexamethasone (DEX) during the fetal stage. Previously, this resistance of the adult SCN clock was attributed to a developmental loss of the glucocorticoid receptor (GR).

Bioethical Issues as Triggers of Religious Transformation in Orthodox Christianity
Bioethics, Volume 40, Issue 1, Page 45-51, January 2026.ABSTRACT The advent of new biomedical technologies has given rise to an emerging area of sociocultural discourse. The sociocultural perception of these technologies is contingent upon a number of factors, including the prevailing attitudes within dominant religious traditions. Religious bioethics is fundamentally distinct from secular bioethics.

Marine Mammal Science, Volume 42, Issue 1, January 2026.ABSTRACT In 2024, an expedition was conducted off northwestern Baja California, México, to find and identify the beaked whale species that produced the BW43 echolocation pulse previously recorded in this area and elsewhere in the North Pacific. There were five Mesoplodon sightings and 21 BW43 acoustic detections on both a towed array and drifting pole ...

Smooth Muscle Mechanosensitivity Generates and Maintains Pressure Gradients Across the Intestine
Neurogastroenterology &Motility, Volume 38, Issue 1, January 2026.Mechanosensitivity of the smooth muscle induces a positive‐feedback loop that spontaneously generates pressure gradients across gut segments and stabilizes initially applied pressure gradients. It can act jointly or compete with the pressure gradient induced by directional peristaltic waves.

Reproduction in Domestic Animals, Volume 61, Issue 1, January 2026.ABSTRACT Follicle‐stimulating hormone (FSH) plays an important role in regulating reproductive events, particularly follicular development and oocyte competence acquisition. Some studies using FSH protocols in zebu cattle were performed, but data regarding its application in the Red Sindhi breed are scarce and therefore warranted. In this context, this
