Establishment and evaluation of a novel rat model of the fourth ventricle hemorrhage

Animal Models and Experimental Medicine, EarlyView.
In this study, a novel rat model of fourth ventricle hemorrhage was established via autologous blood injection through the foramen of Magendie. Anesthetized rats were positioned in a stereotaxic apparatus with their heads tilted downward at an angle of approximately 20° relative to the vertical axis.

Pathological Disulfide Bond Crosslinking: Molecular Insights into Amyloidogenesis and Diseases Progression

ChemBioChem, EarlyView.
This review explores pathological disulfide‐crosslinking as a key driver of amyloidogenic protein misfolding and aggregation. Oxidative and ER stress pathways contributing to disease progression are discussed and emerging therapeutic strategies targeting disulfide‐linked aggregates in neurodegenerative and systemic amyloid diseases are examined ...

Subarachnoid Hemorrhage Increases Level of Heme Oxygenase-1 and Biliverdin Reductase in the Choroid Plexus

Frontiers in Cellular Neuroscience, 2020
Subarachnoid hemorrhage is a specific, life-threatening form of hemorrhagic stroke linked to high morbidity and mortality. It has been found that the choroid plexus of the brain ventricles forming the blood-cerebrospinal fluid barrier plays an important ...

Embryonic cerebrospinal fluid pressure in fetal mice in utero: External factors pressurize the intraventricular space

Developmental Dynamics, EarlyView.
Abstract Background Previous experiments inducing leakage of embryonic cerebrospinal fluid (CSF) suggest the necessity of intraventricular CSF pressure (PCSF) for brain morphogenesis. Nevertheless, how embryonic PCSF occurs is unclear, especially in utero. Results Using a Landis water manometer, we measured PCSF in fetal mice isolated from the amniotic

Choroid Plexus Carcinoma

Archives of Pathology & Laboratory Medicine, 2008
Abstract Choroid plexus carcinoma is an uncommon neoplasm of the central nervous system most commonly found in the pediatric population. It is associated with a dismal prognosis, especially if incompletely resected. Accurate histopathologic diagnosis is imperative, and this neoplasm should always be included in the differential diagnosis
