Angiopoietin-1 Knockout Mice as a Genetic Model of Open-Angle Glaucoma.

Purpose: A leading cause of blindness worldwide, glaucoma is often caused by elevated intraocular pressure (IOP) due to impaired aqueous humor outflow from the anterior chamber through Schlemm's canal (SC) and the trabecular meshwork. Despite the large clinical burden, glaucoma research and drug development are hindered by a limited selection of preclinical models that accurately recapitulate human disease. Here, we propose that conditional knockout mice may provide one such model.

Prospective respiratory triggering improves high-resolution brachial plexus MRI quality.

Background: Oblique sagittal MRI sequences, orthogonal to the longitudinal axis of the brachial plexus, can reliably depict morphologic and signal abnormalities. However, nerve visualization may be obscured by ghosting artifact from periodic respiratory motion. Respiratory triggering (RT) with a thoracoabdominal bellows can reduce ghosting artifact, but it is not routinely used for brachial plexus MRI.

Treatment Gap in Primary Prevention Patients Presenting With Acute Coronary Syndrome.

Previous studies assessing healthcare provider compliance to the 2013 American College of Cardiology/American Heart Association (ACC/AHA) cholesterol guidelines indicate a significant underuse of statin therapy at appropriate intensity. However, data are limited in primary prevention patients. Our study aimed to evaluate the impact of the 2013 ACC/AHA guidelines through a retrospective analysis of primary prevention patients presenting with first time acute coronary syndrome (ACS).
