Recent advances of nanobiocatalytic approaches have improved the performance of protein digestion by using various nanomaterials such as nanoporous materials, magnetic nanoparticles, and polymer nanofibers. Especially, the unprecedented success of trypsin stabilization in the form of trypsin-coated nanofibers, showing no activity decrease under repeated uses for 1 year and retaining good resistance to proteolysis, has demonstrated its great potential to be employed in the development of automated, high-throughput, and on-line digestion systems. This review discusses
recent developments of nanobiocatalytic approaches for the improved performance of protein digestion in speed, detection sensitivity, recyclability, and trypsin stability. In addition, we also introduce approaches for protein digestion under unconventional energy click here input for protein denaturation and the development of microfluidic enzyme reactors that can benefit from recent successes of these nanobiocatalytic approaches.”
“Objective: To retrospectively determine the imaging features of coronary artery anomalies depicted at dual-source computed tomographic coronary angiography (DSCT-CA).
Methods: We reviewed the case histories of 12,145 patients with
suspected coronary arterial disease who underwent DSCT-CA at our institution. Multiplanar reformation, maximum-intensity projection, and volume-rendered imaging were performed on an offline workstation. Each study was assessed retrospectively for the origin and course buy Selisistat of the anomalous coronary artery by a minimum of 2 cardiovascular radiologists; decisions were made in consensus.
Results: There were 124 (1.02%) patients with coronary anomalies. Fifty-one patients demonstrated www.selleck.cn/products/sc75741.html an anomalous origin of the right coronary artery from the left sinus
of Valsalva or the left main artery. An anomalous origin of a left circumflex artery from the right sinus of Valsalva or the right coronary artery was depicted in 17 patients. An anomalous origin of a left main artery from the right sinus of Valsalva was depicted in 1 patient. A single coronary artery was shown in 4 patients, and congenital transposition of the great arteries was associated with this anomaly in 1 patient. In the remaining 50 patients, coronary artery fistulas were identified. Eight patients were referred after an equivocal conventional coronary angiogram.
Conclusions: DSCT-CA is a reliable noninvasive tool that allows accurate delineation of coronary arterial anomalies in an appropriate clinical setting and provides detailed 3-dimensional anatomic information that may be difficult to obtain with invasive coronary angiography.
