Beginning To Address An Implementation Gap In Asthma: Clinicians' Views Of Prescribing Reliever Budesonide-Formoterol Inhalers And Smart In The United States, James G Krings, Tejas C Sekhar, Vanessa Chen, Kathryn V Blake, Kaharu Sumino, Aimee S James, Amber K Clover, Eric J Lenze, Ross C Brownson, Mario Castro

2020-Current year OA Pubs

BACKGROUND: The Global Initiative for Asthma and National Asthma Education and Prevention Program recently made paradigm-shifting recommendations regarding inhaler management in asthma. The Global Initiative for Asthma now recommends that combination inhaled corticosteroid (ICS)-formoterol inhalers replace short-acting β-agonists as the preferred reliever therapy at all steps of asthma management. Although the most recent guidelines of the National Asthma Education and Prevention Program did not review reliever ICS-formoterol usage in mild asthma, they similarly recommended single maintenance and reliever therapy (SMART) at steps 3 and 4 of asthma management. Despite these recommendations, many clinicians-particularly in the United States-are not prescribing new …

Novel Roles For The Transcriptional Repressor E4bp4 In Both Cardiac Physiology And Pathophysiology, Sobuj Mia, David R Rawnsley, Sumanth D Prabhu, Abhinav Diwan, Et Al.

2020-Current year OA Pubs

Circadian clocks temporally orchestrate biological processes critical for cellular/organ function. For example, the cardiomyocyte circadian clock modulates cardiac metabolism, signaling, and electrophysiology over the course of the day, such that, disruption of the clock leads to age-onset cardiomyopathy (through unknown mechanisms). Here, we report that genetic disruption of the cardiomyocyte clock results in chronic induction of the transcriptional repressor E4BP4. Importantly, E4BP4 deletion prevents age-onset cardiomyopathy following clock disruption. These studies also indicate that E4BP4 regulates both cardiac metabolism (eg, fatty acid oxidation) and electrophysiology (eg, QT interval). Collectively, these studies reveal that E4BP4 is a novel regulator of both …

Kir1.1 And Sur1 Are Not Implicated As Subunits Of An Adenosine Triphosphate-Sensitive Potassium Channel Involved In Diazoxide Cardioprotection, Jie Wang, Kyriakos Papanicolaou, Robert Tryon, Janelle Sangalang, Ben Salazar, Alejandro Suarez-Pierre, Jie Dong, Anson Lee, Emily Larson, Sari Holmes, Brian O'Rourke, Colin Nichols, Jennifer Lawton

2020-Current year OA Pubs

OBJECTIVE: The adenosine triphosphate-sensitive potassium channel opener diazoxide mimics ischemic preconditioning and is cardioprotective. Clarification of diazoxide's site and mechanism of action could lead to targeted pharmacologic therapies for patients undergoing cardiac surgery. Several mitochondrial candidate proteins have been investigated as potential adenosine triphosphate-sensitive potassium channel components. Renal outer medullary potassium (Kir1.1) and sulfonylurea sensitive regulatory subunit 1 have been suggested as subunits of a mitochondrial adenosine triphosphate-sensitive potassium channel. We hypothesized that pharmacologic blockade or genetic deletion (knockout) of renal outer medullary potassium and sensitive regulatory subunit 1 would result in loss of diazoxide cardioprotection in models of global …

Modified Bare-Back Micro-Retrograde Tibial Arterial Access To Facilitate Peripheral Endovascular Therapy, Faiz Gani, Momodou L Jammeh, Mohamed A Zayed

2020-Current year OA Pubs

Patients with critical limb threatening ischemia often present with complex segmental peripheral arterial chronic total occlusions, which might not be amenable to traditional antegrade revascularization techniques. For these patients, alternative retrograde revascularization techniques could be necessary. In the present report, we describe a novel modified retrograde cannulation technique using a bare back technique that eliminates the need for conventional tibial access sheath placement and, instead, facilitates distal arterial blood sampling, blood pressure monitoring, retrograde administration of contrast agents and vasoactive substances, and a rapid-exchange strategy. This cannulation strategy can serve as part of the armamentarium in the treatment of patients …

The Effect Of Fibre Cell Remodelling On The Power And Optical Quality Of The Lens, J Rodriguez, Q Tan, H Šikić, L A. Taber, S Bassnett

2020-Current year OA Pubs

Vertebrate eye lenses are uniquely adapted to form a refractive index gradient (GRIN) for improved acuity, and to grow slowly in size despite constant cell proliferation. The mechanisms behind these adaptations remain poorly understood. We hypothesize that cell compaction contributes to both. To test this notion, we examined the relationship between lens size and shape, refractive characteristics and the cross-sectional areas of constituent fibre cells in mice of different ages. We developed a block-face imaging method to visualize cellular cross sections and found that the cross-sectional areas of fibre cells rose and then decreased over time, with the most significant …
