An Evaluation of Oral Subchronic Toxicity of Maizinol (UP165), a Zea mays Leaf Extract
Journal of Applied Toxicology, EarlyView.ABSTRACT Maize (Zea mays) has been consumed by humans for millennia and represents the third most abundant crop grown globally. Maize and maize‐derived products have a long history of safe consumption from bread and other cereal products in human diets worldwide. Aside from key dietary components like carbohydrates and proteins, the corn plant contains

Journal of Applied Toxicology, EarlyView.ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.ABSTRACT In fish, sex determination and gonadal development are controlled by various genetic and environmental factors. In this study, experiments were conducted on the estuarine mummichog (Fundulus heteroclitus) to investigate gonadal differentiation following exposure to the synthetic estrogen, 17α‐ethinylestradiol (EE2).

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.ABSTRACT The southern alligator lizard (Elgaria multicarinata) exhibits prolonged mate‐holding behavior. This behavior maybe be underpinned by a phenomenon known as sustained force, observed in the jaw muscles of this species, in which the muscle fails to relax between subsequent contractions.

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.ABSTRACT Animals with seasonal reproductive cycles, as the Roe deer (Capreolus capreolus), have developed mechanisms to synchronize reproduction with the environmental cycle in order to optimize reproductive success through melatonin. Angiogenesis and oxidative stress are key processes in spermatogenesis, contributing to testicular remodeling and ...

Escaping Constraints to Innovate: Maternal Neofunctionalization in a HoxB4 Duplicate
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.Whole‐genome duplication in Xenopus laevis generated duplicated Hox genes that are largely constrained in sequence and developmental expression. However, HoxB4L uniquely acquired maternal expression through cis‐regulatory and protein structural divergence, illustrating how gene duplication enables transcription factors to escape pleiotropic constraints

Overview of Diagnostic Ultrasound Safety
Journal of Ultrasound in Medicine, EarlyView.Ultrasound is widely regarded as a safe imaging modality; however, emerging ultrasound‐based techniques—such as shear wave elastography and contrast‐enhanced ultrasound—operate with varying acoustic output parameters that may approach or exceed traditional diagnostic limits. As these technologies are increasingly integrated into human research studies,
