Three Rare Structural Anomalies: Right Aberrant Subclavian Artery, , and Isolated Left Vertebral Artery All Associated with Type B Aortic Dissection.

Introduction And Background: Right aberrant subclavian artery accounts for 0.5-1.8% of the population as the most frequently encountered aortic arch anomaly, while the prevalence of an isolated left vertebral artery ranges from 3 to 8%.

Short-term outcomes of endoscopic sleeve gastroplasty in 1000 consecutive patients.

Background And Aims: Questions related to the safety and long-term efficacy of endoscopic sleeve gastroplasty (ESG) are not yet answered. Here we report weight loss, morbidity, revisions, and comorbidity resolution during the first 18 months after primary ESG.

Methods: This is a consecutive case series from a prospective observational study executed in a specialized center with a standardized pathway for multimodal management of obesity.

Microfabrication of Net Shape Zirconia/Alumina Nanocomposite Micro Parts.

Recently, there are growing demands in manufacturing of net shape micro parts for wide range of applications due to the increasing interest in miniaturization. In this paper, the fabrication of tetragonal phase zirconia/alumina (YSZ/Al₂O₃) nanocomposite micro-parts with high quality is presented. The fabrication process is based on soft lithography and colloidal powder dispersion.
