Anatomical description of the jaw muscles and theoretical bite force assessment in South American opossums using manual and digital dissection methods

open access: yesJournal of Anatomy, EarlyView.
Manual and virtual dissections were employed to examine the masticatory muscle architecture and bite force of three South American marsupials. The organisation of the muscles differed between species, with predicted bite forces exceeding previous estimates.

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds

open access: yesJournal of Anatomy, EarlyView.
The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.

Genetic and Pharmacologic Inhibition of Myostatin Restores Muscle Mass in a Dynamin 2‐Related Centronuclear Myopathy Mouse Model

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 5, October 2026.
ABSTRACT Background Autosomal dominant centronuclear myopathy (ADCNM), most commonly caused by mutations in the dynamin 2 (DNM2) gene, is a rare congenital myopathy characterized by progressive muscle weakness and atrophy. Myostatin, a key negative regulator of skeletal muscle mass, has shown therapeutic potential in several models of neuromuscular ...

Three-dimensional architecture of the whole human soleus muscle in vivo [PDF]

open access: yesPeerJ, 2018
Background Most data on the architecture of the human soleus muscle have been obtained from cadaveric dissection or two-dimensional ultrasound imaging. We present the first comprehensive, quantitative study on the three-dimensional anatomy of the human ...

Innovative Dose–Response Assessment of the Metaboreflex With Indirect Control of Intramuscular Metabolic Perturbation in Humans

open access: yesActa Physiologica, Volume 242, Issue 10, October 2026.
ABSTRACT Aim We aimed to evaluate an innovative dose–response approach to assess the metaboreflex with control of intramuscular metabolic perturbation (concept of metaboreflex gain). We also investigated potential sex differences in the metaboreflex using this new approach.

Hoffmann's two‐toed sloth II: Muscle architectural properties in the thoracic limb of Choloepus (Pilosa: Xenarthra)

open access: yesJournal of Anatomy, Volume 249, Issue 4, Page 737-758, October 2026.
Two‐toed sloths use their thoracic limbs for more frequent and greater suspensory support than three‐toed sloths and have muscle architectural properties consistent with stability of the pectoral girdle, enhanced flexor force/torque applied at the shoulder and elbow joints, and grip on the support as indicated by their myology. Abstract Two‐toed sloths

Clinical value of ultrasonography in assessing skeletal muscle status in patients with type 2 diabetes mellitus

open access: yesXin yixue
Objective To investigate the clinical value of multiparametric ultrasonography in assessing skeletal muscle morphological and elastic changes in patients with type 2 diabetes mellitus (T2DM), and to screen effective diagnostic indicators for diabetes ...

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

open access: yesThe Anatomical Record, Volume 309, Issue 9, Page 2411-2423, September 2026.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

Effect of standard- versus high-protein enteral feeding on rectus femoris muscle mass in mechanically ventilated traumatic brain injury patients: a prospective randomized study in Egypt and the United States [PDF]

open access: yesAcute and Critical Care
Background Critically ill patients with muscle wasting experience prolonged intensive care unit (ICU) stays, delayed weaning, and higher mortality. Trauma-induced stress disrupts protein metabolism, leading to immunosuppression and muscle loss.

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

open access: yesThe 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 ...
