TTC21B: From Modifier to Causative Gene in Joubert Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Biallelic pathogenic variants in TTC21B, encoding the retrograde intraflagellar transport protein IFT139, are a known cause of renal and skeletal ciliopathies. Single heterozygous variants in this gene were found to be enriched in a cohort of patients with various ciliopathy phenotypes, including three individuals with Joubert syndrome (JS), a

Convexity subarachnoid hemorrhage: clinical features and etiology of an Argentinian cohort

open access: yesArquivos de Neuro-Psiquiatria
Nontraumatic convexity subarachnoid hemorrhage is an increasingly recognized subtype of subarachnoid bleeding. Objective: Our aim was to describe the etiology and clinical features of a cohort of patients with convexity subarachnoid hemorrhage. Methods:

A mouse model of mechanical stress injury to the basal ganglia using thermosensitive PNIPAM hydrogel for intracerebral hemorrhage research

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In this study, we established a novel mouse model of intracerebral hemorrhage (ICH) by stereotactically injecting thermosensitive PNIPAM hydrogel into the internal capsule to impose localized mechanical stress on the corticospinal tract, which provides a straightforward and reproducible tool for preclinical studies on focal mechanical stress–induced ...

Animal stroke models and outcome evaluation: A review

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Rodents are the preeminent stroke model species. Large animal models exist too, but are poorly standardized. Ischemic and hemorrhagic experimental models are available, with the intraluminal filament model being predominant. Outcomes are evaluated via quantifying subjects' sensorimotor impairment, cognitive memory faculties, degree of cellular ...

Animal models for investigating post‐stroke cognitive impairment: A neurovascular trafficking perspective

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Animal models enable mechanistic testing of how ischemic injury disrupts neurovascular trafficking and drives cognitive vulnerability after stroke. Complementary models capture distinct vascular, cellular, white matter, and cognitive features of PSCI.

Increased sympathetic nervous activity in patients with nontraumatic subarachnoid hemorrhage

open access: yes, 2000
Activation of the sympathetic nervous system, which leads to elevation of circulating catecholamines, is implicated in the genesis of cerebral vasospasm and cardiac aberrations after subarachnoid hemorrhage.

Isolated Intraventricular Hemorrhage Associated with Cerebral Vasospasm and Delayed Cerebral Ischemia following Arteriovenous Malformation Rupture

open access: yes, 2018
Background: Although it is well characterized in aneurysmal subarachnoid hemorrhage, vasospasm is exceedingly rare following cerebral arteriovenous malformation (AVM) rupture. Subsequently, this complication is poorly characterized with regard to delayed

Mechanical Thrombectomy Versus Medical Management for Large Ischemic Core Stroke Identified before Inter‐Hospital Transfer: A Post Hoc Analysis of the LASTE Trial

open access: yesAnnals of Neurology, EarlyView.
Objective This study assessed the efficacy of thrombectomy in acute ischemic stroke because of large‐vessel occlusion (AIS‐LVO) initially admitted to primary stroke centers (PSC) and subsequently transferred to a comprehensive stroke center (CSC), with a large ischemic core identified before transfer.

Cerebral No‐Reflow after Thrombectomy: International Delphi Consensus on Definition and Imaging Assessment

open access: yesAnnals of Neurology, EarlyView.
Background The operational definition and imaging assessment of the no‐reflow phenomenon, a potential contributor to poor clinical outcome despite successful thrombectomy, remains debated. We aimed to develop expert‐based international consensus on the definition, assessment, and reporting standard of cerebral no‐reflow post‐thrombectomy. Methods Three‐

Centrum Semiovale Perivascular Spaces Predict First Hemorrhagic Lesion in Asymptomatic Amyloid‐Positive Individuals

open access: yesAnnals of Neurology, EarlyView.
Objective Identification of cerebral amyloid angiopathy (CAA) before its hemorrhagic manifestations remains limited. We aimed to determine whether severe enlarged perivascular spaces in the centrum semiovale (EPVS‐CSO) identify a prehemorrhagic stage of sporadic CAA by predicting the first appearance of CAA‐related hemorrhagic lesions or incident ...
