Animal Models and Experimental Medicine, EarlyView.We observed a negative effect of brachycephalic obstructive airway syndrome (BOAS) in a staggered manner based on the severity of the condition on respiratory and cardiac patterns, glycemia, acid–base balance, fetal growth, and uterine artery hemodynamics, thus requiring adaptations within the fetal–placental unit. Severely affected bitches had uterine

Gigantic cutaneous horn: A case report and review of literature
Academic Medicine & Surgery: Cutaneous horns are rare, keratinized protrusions that resemble animal horns. The prevalence and incidence of cutaneous horns are not well-documented, but they are more commonly found in individuals aged 60 to 80, particularly in sun-exposed areas ...

Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire
Advanced Physics Research, EarlyView.According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.

The Function of Horn Ridges for Impact Damping
BiomimeticsThis study explores the damping effects of ram horn ridges on mechanical impacts resulting from ramming. We measured the amplitudes and frequencies of ridges along the axial (pitch) direction of the ridges of ram horns obtained from eight specimens ...

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds
The Anatomical Record, EarlyView.Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

The Anatomical Record, EarlyView.A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

The Anatomical Record, EarlyView.Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...
