Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

The Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

Comparative histological, histochemical, and histometric evaluation of the esophagus in two avian species with different feeding habits (Ciconia ciconia and Buteo buteo)

The Anatomical Record, EarlyView.
Histological structure of esophagus. Abstract The aim of this study was to conduct a comparative evaluation of the histological and histochemical organization of the esophagus in two avian species with different feeding ecologies. A total of 6 individuals were used for this purpose (3 storks, 3 common buzzards).

Lysophosphatidic acid–mediated NF-κB activation promotes FOXC2 expression essential for lymphatic valve development

The Journal of Clinical Investigation
The lymphatic system maintains tissue fluid balance, and FOXC2 mutations cause lymphoedema-distichiasis syndrome, which is characterized by lymphatic valve defects.

VEGFR2 is required for VEGF-C–VEGFR3–PI3Kα-mediated sprouting lymphangiogenesis

Nature Communications
Lymphatic vessels are essential for tissue homoeostasis and their growth is regulated by vascular endothelial growth factor C (VEGF-C) signalling through VEGFR3.

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

Animal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

Animal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

Age‐Associated B Cells Contribute to Inflammation Via Antibody‐Independent Mechanisms in Takayasu Arteritis

Arthritis &Rheumatology, EarlyView.
Objective Although Takayasu arteritis (TAK) is not a prototypical autoantibody‐mediated disease, accumulating evidence suggests that B cells are involved. This study aimed to investigate the pathway of B cell activation and its contributions to TAK pathogenesis. Methods Histologic analysis of paravascular lymph nodes and affected arteries was conducted

Lymphangiogenesis in hypercholesterolemic skin: A comparative study of xanthomatous and non-xanthomatous lesions

JID Innovations
While hypercholesterolemia is the primary driver of atherosclerosis, emerging evidence indicates that lymphatic vessels are critical for cholesterol transport and become impaired under hyperlipidemic conditions.

Student and staff experiences of interactive digital models when learning animal anatomy

Anatomical Sciences Education, EarlyView.
Abstract Compared to human medical sciences, digital models of animals are rare, often behind subscription services and are comparatively lacking in interactivity and accessibility features. This study explores how digital models are currently being used to teach animal anatomy, providing the data required to construct the best anatomical models ...
