Mussel Spermatozoa Express a Specific Isoform of the Catalytic Subunit of cAMP‐Dependent Protein Kinase

Molecular Reproduction and Development, Volume 93, Issue 8, August 2026.
ABSTRACT cAMP‐dependent protein kinase (PKA) plays a central role in regulating sperm motility in both invertebrates and mammals. The sea mussel Mytilus galloprovincialis provides a valuable model for investigating the molecular mechanisms underlying gamete activation in externally fertilizing organisms.

Unilateral ductus deferens aplasia with terminal cystic dilation in a Bernese mountain dog

Veterinary Record Case Reports, Volume 14, Issue 3, August 2026.
Abstract An incidental caudal abdominal mass was discovered in a 5‐year‐old, male, entire Bernese mountain dog. Investigations showed a terminal cystic dilation of the left ductus deferens. Castration, along with surgical resection of the mass, was performed, and histopathology of the mass and ductus deferens was consistent with segmental aplasia of ...

Spontaneous miscarriage after intracytoplasmic sperm injection with frozen sperm of patients with testicular germ cell tumour

BJU International, Volume 138, Issue 2, Page 315-323, August 2026.
Objective To clarify the impact of chromosomal aberrations on the offspring of patients with testicular germ cell tumour (TGCT) by evaluating the outcomes of intracytoplasmic sperm injection (ICSI). Patients and Methods Under the ethical review of Yokohama City University, 12 patients with TGCT and 25 with non‐TGCT cancer who had cryopreserved sperm ...

Endothelium‐ and epithelium‐derived novel endogenous catecholamines as modulators of the autonomic nervous system

British Journal of Pharmacology, Volume 183, Issue 15, Page 4091-4110, August 2026.
Abstract Catecholamines are classically viewed as neuronal transmitters and adrenal hormones; however, accumulating evidence demonstrates that sources other than nerve fibres and adrenal medulla play a fundamental role in local organ regulation. Physiological paradoxes, such as preserved organ function after denervation or transplantation, challenge a ...
