A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

The Anatomical Record, EarlyView.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

Expression of a catalytically inactive mutant form of glutathione peroxidase 4 (Gpx4) confers a dominant-negative effect in male fertility. [PDF]

, 2015
The selenoenzyme Gpx4 is essential for early embryogenesis and cell viability for its unique function to prevent phospholipid oxidation. Recently, the cytosolic form of Gpx4 was identified as an upstream regulator of a novel form of non-apoptotic cell ...

Modern competency‐based teaching of human sexual development

Anatomical Sciences Education, EarlyView.
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.

Mapping opioid exposure through prescription data and postmortem analysis of opioid drugs in multiple tissues

British Journal of Clinical Pharmacology, EarlyView.
Background and Purpose Although opioids are central to end of life (EoL) care, tissue‐level opioid exposure remains poorly understood. The objective of this study was to characterize the relationship between prescription‐derived morphine equivalent daily dose (MEDD) and measured morphine concentrations across multiple organs.

Paternal Exposure to the Neonicotinoid Pesticide Clothianidin Alters Sperm MicroRNA Profiles in Mice and Intergenerationally Reduces Locomotor Activity in Male Offspring

Journal of Applied Toxicology, EarlyView.
ABSTRACT Accumulating evidence suggests that paternal environmental factors have epigenetic effects on sperm and influence offspring. Neonicotinoid pesticides (NNs), which are widely used around the world, are known to affect offspring phenotypes through maternal exposure in mice, but the effect of the paternal exposure remains unknown.
