Whether the dilatation of proximal aorta in patients with bicuspid aortic valve is secondary to hemodynamic effects related to the abnormal aortic valve or a primary manifestation of the genetic disorder remains controversial. We discuss in this paper the recent data on the BAV function and transvalvular flow patterns in relation with the dilatation type of the proximal aorta. Different morphol...

We consider an extension of the proximal minimization algorithm where only some of the minimization variables appear in the quadratic proximal term. We interpret the resulting iterates in terms of the iterates of the standard algorithm and we show a uniform descent property, which holds independently of the proximal terms used. This property is used to give simple convergence proofs of parallel...

Introduction: Obstructive coronary artery disease (CAD) in proximal segments is associated with a poor prognosis. However, the contribution of plaque location to major adverse cardiovascular events (MACE) among patients nonobstructive CAD not well defined. We examined MACE risk relation non-obstructive by CT angiography (CCTA).

OBJECTIVES The aim was to analyze influential factors and effects of proximal contact loss between implant-supported fixed dental prostheses (FDP) and adjacent teeth. MATERIAL AND METHODS Ninety-four subjects treated with 135 FDPs supported by 188 implants were included. Degree of proximal contact tightness, food impaction, and periodontal/peri-implant tissue conditions were assessed in 191 p...

background and aims. with the introduction of cone beam computed tomography (cbct) in dentistry, a question has been raised whether the technique significantly increases the diagnostic accuracy in comparison with other techniques or not. therefore, the present study was undertaken to assess the accuracy of cbct modality in detecting proximal carious lesions as compared to conventional periapica...

background: colorectal cancer (crc) is the second cause of cancer-related deaths worldwide. there have been several studies reporting the proximal tumor shift, especially in western countries. in the present study, we investigated the clinicopathologic and anatomical distributions of colorectal tumors in iranian crc patients. materials and methods: in this retrospective cohort study,258 patient...
