Obstructive sleep apnea syndrome (OSA) and restless legs syndrome (RLS) with periodic limb movement during sleep (PLMS) are two sleep disorders characterized by repetitive respiratory or movement events associated with cortical arousals. We compared the cerebral hemodynamic changes linked to periodic apneas/hypopneas with arousals (AHA) in four OSA-patients with periodic limb movements (PLMA) w...
The effects of hypertension on the outcomes during perioperative period are still unclear. No specific systolic or diastolic blood pressure measurement has been determined as cutoff point to continue with surgical plan adjourn.This study is designed a narrative review available scientific evidence management hypertension. A non-systematic was conducted in Pubmed considering title and abstract; ...
This paper presents a machine learning model to predict the effect of Al2O3 nanoparticles content on wear rates in Cu-Al2O3 nanocomposite prepared using situ chemical technique. The developed is modification random vector functional link (RVFL) algorithm artificial hummingbird (AHA). objective AHA used find optimal configuration RVFL enhance prediction nanoparticles. preparation composite was d...
A Proud History In July 2019, the American Heart Association (AHA) Council on Basic Cardiovascular Science (BCVS) will celebrate its 20th anniversary. For this first News and Views: From the BCVS Chair for Circulation Research, I thought it would be most appropriate to provide a brief history and mission statement of the AHA BCVS Council. In 1924, 6 leading cardiologists across the nation—Drs L...
655 Heart failure (HF) is a complex syndrome in which structural or functional cardiac abnormalities impair the filling of ventricles or left ventricular ejection of blood. HF disproportionately occurs in those ≥65 years of age. Among the estimated 1.5 to 2 million residents in skilled nursing facilities (SNFs) in the United States, cardiovascular disease is the largest diagnostic category, and...
Although ischemic stress, including ischemic preconditioning (IP), activates p38 mitogen-activated protein kinase (MAPK), the relationship between p38 MAPK activation and the underlying cellular mechanisms of cardioprotection by IP is not verified in vivo. We examined the effects of the selective p38 MAPK inhibition on the cardioprotective effect of IP in the open-chest dogs. The coronary arter...
2012 ACCF/AHA Focused Update of the Guideline for the Management of Patients With Unstable Angina/Non–ST-Elevation Myocardial Infarction (Updating the 2007 Guideline and Replacing the 2011 Focused Update) A Report of the American College of Cardiology Foundation/American Heart Association Task Force on Practice Guidelines Developed in Collaboration With the American College of Emergency Physici...
Recent studies have shown that antiphospholipid (aPL) enhances expression of intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin on endothelial cells (ECs) and that these effects are correlated with increased adhesion of leukocytes to endothelium in cremaster muscle in vivo and with thrombosis in a mouse model. Activation of ECs by aPL may...
average for alternating pairs is also remarkably close to the ratio of the control beat. In other words, one of the paired beats is actually greater than average in its index of performance, and one is less. This observation in dogs, plus the widely recognized effects of potentiation in the postextrasystolic beat, make a strong case for potentiation alternating with deletion as the mechanism of...
Presentation formats used for publishing information on the World Wide Web are constantly evolving. Simultaneously, the range of devices used to access this information is expanding. In education adaptive hypermedia methods and techniques are often used to tailor a presentation to the individual user. Typical adaptation software can only adapt simple presentation formats like HTML (with embedde...
