Genetic Variation in ADHD‐Related Risk Genes in an Indigenous Population of the Amazon

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Attention‐Deficit/Hyperactivity Disorder (ADHD) is a highly heritable neurodevelopmental disorder; however, its genetic architecture remains poorly explored in Indigenous populations. This study aimed to analyze and characterize genetic variation in 11 genes (ADGRL3, CDH8, DCC, DUSP6, FOXP1, FOXP2, MEF2C, PCDH7, SEMA6D, SORCS3, and ST3GAL3 ...

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

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

The Anatomical Record, EarlyView.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Early evolution of the gular musculature and its innervation in ray‐finned fishes

The Anatomical Record, EarlyView.
Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

Cardiac morphological and morphometric analysis of Ardea alba

The Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...
