Diurnal variation of non-specular meteor trails [PDF]

Annales Geophysicae, 2009
We present results of simulated radar observations of meteor trails in an effort to show how non-specular meteor trails are expected to vary as a function of a number of key atmospheric, ionospheric and meteoroid parameters.

Metabolic and biochemical profiling reveals phenotypic heterogeneity in Zucker diabetic fatty rats

Animal Models and Experimental Medicine, EarlyView.
Genetically uniform Zucker Diabetic Fatty (ZDF) rats spontaneously develop four distinct metabolic phenotypes despite identical housing and diet conditions. Each phenotype exhibits unique biomarker signatures encompassing glucose homeostasis, insulin secretion, polyol pathway activation, oxidative stress, inflammatory cytokines, and neurotrophic ...

Phenotypic profiling of pristane‐induced mimicking human systemic lupus erythematosus in Macaca fascicularis

Animal Models and Experimental Medicine, EarlyView.
Pristane (5 mL/kg) induced a robust systemic lupus erythematosus (SLE)‐like phenotype in Macaca fascicularis, marked by elevated antinuclear antibody (ANA) levels and systemic clinical, hematological, and biochemical changes. This model closely reflects human SLE and provides a translational platform for disease studies and therapeutic evaluation ...

Population-, sex- and individual level divergence in life-history and activity patterns in an annual killifish [PDF]

PeerJ, 2019
Variation in life-history strategies along a slow-fast continuum is largely governed by life-history trade-offs. The pace-of-life syndrome hypothesis (POLS) expands on this idea and suggests coevolution of these traits with personality and physiology at ...

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

The Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Patterns of interspecific variation in labial microarchitecture among anthropoid primates and the evolution of the hominin lips

The Anatomical Record, EarlyView.
Comparative histological and semi‐automated image analysis of primate lips: Masson's trichrome‐stained sagittal sections were segmented to quantify the connective tissue, adipose, and muscular components, enabling interspecific comparisons of labial architecture.

Understanding the spacing of placodes in the eye: A comparative study across age and species

The Anatomical Record, EarlyView.
Abstract The conjunctival placodes of the avian eye form in an intriguing and conserved sequence in a circular annulus around the cornea. These 13–16 placodes develop into papillae that are essential for inducing underlying intramembranous flat bones, known as scleral ossicles, which form an important part of the ocular skeleton.
