Endothelial Netrin‐4 regulates oligodendrocyte precursor cell proliferation and differentiation via ET‐1 signaling in preterm white matter injury

Brain Pathology, EarlyView.
Our findings show early increased Netrin‐4 in mice with PWMI boosts angiogenesis and OPCs proliferation. Later, high levels hinder OPCs differentiation into mature cells, impairing myelination. It may act by stimulating ET‐1 secretion. Abstract Perinatal hypoxia–ischemia is a leading cause of preterm white matter injury (PWMI), yet mechanisms ...

Malignant craniopharyngiomas: Institutional experience and literature review

Brain Pathology, EarlyView.
We report the second case of malignant craniopharyngioma with BAP1 and TP53 mutations. A literature review identified 44 cases of malignant craniopharyngiomas with a median overall survival of 6 months. Eighteen (41%) occurred in patients without any history of radiation, suggesting that mechanisms other than radiation have contributed to their ...

The Bonebridge Active Bone Conduction Hearing Implant: Safety, Effectiveness and Outcomes Based on 355 Patients

Clinical Otolaryngology, EarlyView.
ABSTRACT Objectives This study evaluates the safety and efficacy of the Bonebridge BCI 601 and 602 bone conduction implants in our largest cohort to date of 355 patients. The patients had a wide age range and exhibited conductive, mixed, or single‐sided deafness (SSD). Design All patients underwent Bonebridge implantation.

Comparison of Piezoelectric and High‐Speed Drills for Frontal Beak Osteotomy in Endoscopic Sinus Surgery—Exploratory Study

Clinical Otolaryngology, EarlyView.
ABSTRACT Introduction Frontal beak reduction is a critical and challenging step in endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS). Traditional high‐speed drills can risk thermal injury and soft tissue trauma, whereas piezoelectric surgery uses ultrasonic vibrations for selective bone cutting and may improve surgical precision.

Dysregulation of Rho‐Associated Coiled‐Coil Protein Kinase1 Depletes Neural Stem Cell Pool and Impairs Hippocampal Neurogenesis After Traumatic Brain Injury

Cell Proliferation, EarlyView.
Following TBI, hippocampal neurogenesis in mice is impaired and affects cognitive function. This impairment is associated with the upregulation of p‐AKT/AKT mediated by ROCK1. ABSTRACT Traumatic brain injury (TBI) represents a global health burden, often resulting in persistent neurological deficits due to impaired hippocampal neurogenesis ...

Hypoxia Exacerbates Periapical Periodontitis‐Associated Pathological Bone Loss via the Hypoxia‐Inducible Factor‐2α‐Calmodulin‐Dependent Protein Kinase IV Axis

Cell Proliferation, EarlyView.
Hypoxia exposure activates HIF‐2α, which binds to the Camk4 promoter to enhance RANKL‐mediated osteoclast differentiation, leading to aggravated alveolar bone resorption in periapical periodontitis. ABSTRACT Periapical periodontitis is one of the most common inflammatory bone destructive diseases. Epidemiological evidence suggests that hypoxia exposure,
