Developmental differences in cortical bone structure in chimpanzee and human femora reflect early locomotor independence in humans

The Anatomical Record, EarlyView.
Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

New fossil unveils the dentary anatomy of the rare lepidosauromorph Cargninia enigmatica from the Upper Triassic of Southern Brazil

The Anatomical Record, EarlyView.
Abstract Nowadays, Lepidosauria is a diverse group represented by squamates and the rhynchocephalian tuatara. However, their origins date back to the end of the Permian Period, when the stem lineages Lepidosauromorpha and Archosauromorpha diverged. Within the lepidosauromorph stem lineage, a few species have been described with unstable phylogenetic ...

Local variation in age‐related cortical expansion within and between cross‐sections of distal human long bones

The Anatomical Record, EarlyView.
Abstract Cortical bone expansion is an age‐related process where, through endosteal resorption and periosteal apposition, cross‐sectional diameter increases while cortical thickness decreases in long bone diaphyses. Local variation has been observed in this process between cross‐sectional locations, but few studies have examined directional variation ...

First reports on the relationship between the eggshell and bone mineralization in Rhinoclemmys punctularia punctularia embryos

The Anatomical Record, EarlyView.
Abstract Composed of various minerals, the eggshell provides ideal conditions for embryonic development, and understanding its composition and structure is essential for clarifying its relationship with bone formation. This study characterized the structure and mineral profile of the Rhinoclemmys punctularia punctularia eggshell in relation to ...

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

MicroRNA‐Seq Analysis Reveals a Critical Role for miR‐222 in Bovine Intramuscular Adipogenesis via the DDIT4/mTORC1 Axis

Animal Research and One Health, EarlyView.
Schematic diagram illustrating how miR‐222 promotes bovine intramuscular adipogenesis by targeting DDIT4 to activate the mTORC1 signaling pathway. ABSTRACT Intramuscular fat (IMF) is a key determinant of beef quality, particularly with respect to tenderness, flavor, and juiciness.
