Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

The Anatomical Record, Volume 309, Issue 9, Page 2368-2394, September 2026.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

The Anatomical Record, Volume 309, Issue 9, Page 2315-2330, September 2026.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Variation in parrot jaw musculature

The Anatomical Record, Volume 309, Issue 9, Page 2519-2533, September 2026.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

The Anatomical Record, Volume 309, Issue 9, Page 2346-2367, September 2026.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

m.10010T>C Mitochondrial Disease: A Case Report With Hypoparathyroidism and Review of the Literature

American Journal of Medical Genetics Part A, Volume 200, Issue 8, Page 1856-1861, August 2026.
ABSTRACT Mitochondria are essential intracellular organelles that play a critical role in cellular metabolism, including the regulation of intracellular calcium signaling. Advances in genomic sequencing have facilitated the identification of rare pathogenic mitochondrial DNA (mtDNA) genetic variants in patients with unexplained endocrine disorders.

Effect of Porphyromonas gingivalis Infection on PGC‐1α in Skeletal Muscle After Endurance Training In Vivo

Clinical and Experimental Dental Research, Volume 12, Issue 4, August 2026.
ABSTRACT Objectives It is well known that Porphyromonas gingivalis, a major pathogen in periodontitis, causes systemic diseases. This study investigated the expression of PGC‐1α (the most important factor in muscle mitochondria synthesis) following endurance training to clarify the relationship between P.
