Comparative endocranial anatomy in the crocodylians Leidyosuchus canadensis and Stangerochampsa mccabei from the upper Cretaceous of Alberta, Canada

Journal of Anatomy, EarlyView.
Leidyosuchus canadensis and Stangerochampsa mccabei share endocranial features such as posterior projection of a neurovascular canal in the maxilla and a paratympanic sinus system most similar to those of small‐bodied and young extant crocodylians, suggesting that these pedomorphic features may reflect the ancestral crocodylian condition.

Cavernous sinus invasion by pituitary macroadenomas: neuroradiological, clinical and surgical correlation

Arquivos de Neuro-Psiquiatria, 1998
The classical imaging gold-standard for this diagnosis is the presence of tumor lateral to the carotid artery. Seventeen patients with pituitary macroadenomas with intraoperative confirmation of cavernous sinus invasion were studied with MRI.

Risk factors for thrombotic events in systemic lupus erythematosus patients with antiphospholipid antibodies: insights from morphometric measurements of carotid arteries

Frontiers in Cardiovascular Medicine
ObjectiveTo identify the correlation between thrombosis and atherosclerosis in systemic lupus erythematosus (SLE) patients with antiphospholipid antibodies (aPLs) (SLE/aPLs) through high-resolution magnetic resonance imaging (HR-MRI) of the carotid ...

Neurometabolic Response to Apneic Stimuli Tracks Global Grey Matter Volume Deficits in Patients With Obstructive Sleep Apnea

Journal of Sleep Research, EarlyView.
ABSTRACT Obstructive sleep apnea (OSA) has been linked to cortical atrophy and increased risk of neurodegeneration, a process potentially mediated by neurometabolic dysregulation. Recent work using high temporal‐resolution metabolic MRI found greater changes in the cerebral metabolic rate of oxygen consumption (CMRO2) during cued breath‐hold stimuli ...

First Report on Atrial Leadless Pacing in an Extra‐Cardiac Fontan Patient

Pacing and Clinical Electrophysiology, EarlyView.
Abstract No reports on atrial leadless pacing have been demonstrated in patients with the extra‐cardiac Fontan palliation. We present a case of a patient with an extra‐cardiac Fontan and an alternative to pacing for symptomatic bradycardia in the setting of sinus node dysfunction.

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Carotid sinus hypersensitivity as a cause of multiple falls in an elderly patient: a case report

Revista Médica de Minas Gerais
The carotid sinus is a neurovascular structure composed of baroreceptors responsible for detecting changes in blood pressure. When the baroreflex response of the carotid sinus becomes excessively sensitive, it can result in symptoms such as syncope ...

Systolic‐dominant coronary flow in rats and mice: Challenging the diastolic paradigm across conscious and anaesthetized states

Experimental Physiology, EarlyView.
Abstract Extensive research in humans, dogs, rabbits, rats, mice and other mammals has consistently demonstrated that coronary blood flow (CBF) peaks during ventricular diastole. For example, studies using transthoracic Doppler echocardiography in anaesthetized rats and mice, isolated blood‐perfused rat hearts and Doppler probes sutured to the ...
