Intraoperative intra-aortic balloon pump insertion: step by step.

A 76-year-old patient with non-ST elevation myocardial infarction was admitted to our hospital. Coronary angiography revealed significant left main and two-vessel coronary artery disease. Preoperative testing indicated severe left ventricular dysfunction.

Perventricular device closure of the ventricular septal defects in children-first experience in the United Arab Emirates.

Background: Ventricular septal defect (VSD) is the most common congenital cardiac malformation, accounting for approximately 30% of congenital heart defects. Conventional surgical repair using cardiopulmonary bypass is invasive and associated with morbidities and prolonged hospital stay. With the advent of interventional approaches and availability of different occluding devices, the technique of perventricular device closure is evolving and being implemented successfully in larger groups of patients.

Amino acids biosynthesis in root hair development: a mini-review.

Metabolic factors are essential for developmental biology of an organism. In plants, roots fulfill important functions, in part due to the development of specific epidermal cells, called hair cells that form root hairs (RHs) responsible for water and mineral uptake. RH development consists in (a) patterning processes involved in formation of hair and non-hair cells developed from trichoblasts and atrichoblasts; (b) RH initiation; and (c) apical (tip) growth of the RH.

SimCol3D - 3D reconstruction during colonoscopy challenge.

Colorectal cancer is one of the most common cancers in the world. While colonoscopy is an effective screening technique, navigating an endoscope through the colon to detect polyps is challenging. A 3D map of the observed surfaces could enhance the identification of unscreened colon tissue and serve as a training platform.
