Early life functional transitions impact craniofacial morphology in osteogenesis imperfecta

The Anatomical Record, EarlyView.
Abstract Early life behaviors have a profound role in shaping adult craniofacial morphology. During early life, all mammals undergo the dynamic transition from suckling to mastication, a period coinciding with rapid cranial biomineralization. Osteogenesis imperfecta (OI), a genetic disorder that impacts the production of type I collagen, disrupts ...

Searching for the Grand Tack in Exoplanetary Data [PDF]

A&A 688, L6 (2024)
The grand tack model, more generally called the Masset and Snellgrove mechanism, is a planetary migration model whereby two giant planets via interactions with their natal disk migrated to larger orbital radii. While its relevance in our own Solar System remains in question, the fact that the Masset and Snellgrove mechanism is a general hydrodynamical ...

Linking individual variation in facial musculature to facial behavior in rhesus macaques

The Anatomical Record, EarlyView.
Abstract Facial expression is a key component of primate communication, and primates (including humans) have a complex system of facial musculature underpinning this behavior. Human facial musculature is highly variable across individuals, but to date, whether other primate species exhibit a similar level of inter‐individual variation is unknown ...

Masseter muscle thickness in different skeletal morphology: An ultrasonographic study

Indian Journal of Dental Research, 2010
Background: The thickness of the masseter muscle during relaxation and contraction states was measured by ultrasonography. Subjects were classified according to their sagittal skeletal relationships.

Non‐traumatic myositis ossificans of the Right masseter muscle: a case report and review of the literature

Clinical Case Reports, 2021
Myositis ossificans (MO) is a rare disease in which ossification develops in the muscle or soft tissue. MO traumatica is recognized by ossification of the soft tissues after acute or repetitive trauma, burns, or surgical procedures.

Real-time PCR detection of Toxoplasma gondii in tissue samples of wild boars (Sus scrofa) from southern Italy reveals high prevalence and parasite load. [PDF]

, 2019
Background: Toxoplasmosis is a zoonotic parasitic disease caused by Toxoplasma gondii, a widespread protozoan in the phylum Apicomplexa. In Europe, several studies have demonstrated the presence of the parasite in tissues of wild boars (Sus scrofa), but ...

Micro- and nanostructural characteristics of rat masseter muscle entheses -Characteristics of masseter muscle entheses- [PDF]

, 2019
AbstractThe entheses of the masticatory muscles differ slightly from those of the trunk and limb muscles. However, the bones of the skull are subject to various functional pressures, including masticatory force, resulting in a complex relationship between bone structure and muscle function that remains to be fully elucidated. The present study aimed to

Lagomorph cranial biomechanics and the functional significance of the unique fenestrated rostrum of leporids

The Anatomical Record, EarlyView.
Abstract The crania of leporid lagomorphs are uniquely fenestrated, including the posterior cranial bones and the lateral portion of the maxilla. The functional significance of the highly fenestrated rostrum has received considerably little attention, despite being absent in other mammalian herbivores with a long rostrum.

Local applications of myostatin-siRNA with atelocollagen increase skeletal muscle mass and recovery of muscle function. [PDF]

PLoS ONE, 2013
BACKGROUND: Growing evidence suggests that small-interfering RNA (siRNA) can promote gene silencing in mammalian cells without induction of interferon synthesis or nonspecific gene suppression.
