AIM To test for differences in hemodynamic and analgesic properties in patients with breast cancer undergoing quadrantectomy with paravertebral block (PVB) induced with a solution of either one or two local anesthetics. METHOD A prospective, single-center, randomized, double-blinded, controlled trial was conducted from June 2014 until September 2015. A total of 85 women with breast cancer wer...

Conventional hemodynamic measurements and Doppler echocardiography were used to assess ventricular physiology of the human cardiac allograft and to examine the influence of pertinent clinical factors on chronic myocardial performance. Sixty-four patients (18-55 years old; mean, 39 years) undergoing routine annual hemodynamic assessment were studied. Blood-flow velocity properties across the mit...

Recent advances in functional neuroimaging allow comparisons between individuals with schizophrenia and control groups. Previous studies of schizophrenia have used blocked task paradigms and, more recently, "rapid event-related" designs in which stimuli of different types are presented close together in an intermixed fashion. The validity of between-group comparisons in both of these types of p...

Functional magnetic resonance imaging blood-oxygenation-level-dependent (fMRI-BOLD) signal representing neural activity may be optimized by discriminating MR signal components related to neural activity and those related to intrinsic properties of the cortical vasculature. The objective of this study was to reduce the hemodynamic change independent of neural activity to obtain a scaled fMRI-BOL...

BACKGROUND Losartan is a new specific angiotensin II receptor antagonist with no agonist properties that provides the opportunity to study the consequences of angiotensin II blockade. The objective of the present study was to evaluate the hemodynamic and neurohormonal response to losartan in patients with congestive heart failure. METHODS AND RESULTS After baseline hemodynamic measurements us...

PURPOSE The purpose of this study is to explore the influence of segmentation of the upstream and downstream parent artery and hemodynamic boundary conditions (BCs) on the evaluated hemodynamic factors for the computational fluid dynamics (CFD) analysis of intracranial aneurysms. MATERIALS AND METHODS Three dimensional patient-specific aneurysm models were analyzed by applying various combina...
