Morphometric analysis of posterior cranial fossa and surgical implications

Journal of Craniovertebral Junction and Spine, 2021
Background: Posterior cranial fossa (PCF) is an important area in terms of anatomy and surgery. It is a common site of many neoplastic, vascular, and degenerative lesions. Craniovertebral surgeries require special attention regarding detailed information

ZMAT1 Promotes Osteoclastogenesis Through TRIM46 Mediated YAP1 Degradation and Inhibits Osteoblastogenesis

Advanced Science, EarlyView.
Zmat1 deficiency mitigates pathological bone loss by impairing osteoclastogenesis and promoting osteoblastogenesis. Mechanistically, in osteoclasts, Zmat1 loss relieves transcriptional repression of the E3 ligase TRIM46, promoting YAP1 degradation and inhibiting osteoclastogenic genes.

CT and MR Studies of Giant Dermoid Cyst Associated to Fat Dissemination at the Cortical and Cisternal Cerebral Spaces

Case Reports in Radiology, 2013
This study focuses on CT and MR studies of adult patient with giant lesion of the posterior cranial fossa associated with micro- and macroaccumulations with density and signal like “fat” at the level of the cortical and cisternal cerebral spaces.

Homozygous Achondroplasia With Long‐Term Survival: Growth Patterns, Medical Interventions, and Practice Implications

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Homozygous achondroplasia is widely considered perinatal lethal by the medical community. In this case series, we report two children from a single family with longer‐term survival. One child lived for 17 months and the other was 60 months at the time of publication.

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

The Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...

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

The Anatomical Record, EarlyView.
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.
