Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

open access: yesThe Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Generation of induced pluripotent stem cell line, NCHi027-A, from a female child with Posterior Cloaca (Type B)

open access: yesStem Cell Research
Cloaca is an ultra-rare severe anorectal malformation in females where the gastrointestinal, genital, and urologic systems converge. Posterior Cloaca (Type B) is an extremely rare specific variant, where the urogenital sinus opens just anterior to the ...

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

open access: yesThe 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.

Effect of Cyclic Heat Exposure on the Growth Performance and Metabolism of Broilers Fed Palm Kernel Meal

open access: yesAnimal Research and One Health, EarlyView.
The aim of our study is to evaluate the interaction between HS and the incorporation of PKM in broiler chicken diets, as well as its effect on growth performance and metabolism. Based on the results obtained, PKM supplementation failed to mitigate the adverse effects of heat stress in broiler chickens. ABSTRACT The aim of this study was to evaluate the

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

open access: yesAnimal 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

Hip‐Specific Patient‐Reported Outcomes Strongly Correlate With Pain and Physical Function Metrics but not Mental Health Before and After Hip Arthroscopy for Femoroacetabular Impingement Syndrome

open access: yesArthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To assess the relationships between hip‐specific patient‐reported outcomes (PROs) metrics and general health and pain measures before and after hip arthroscopy for femoroacetabular impingement syndrome (FAIS). Methods This was a retrospective study of patients undergoing hip arthroscopy for FAIS at a single institution from 2014 to 2025.
