SPORADIC SUPRAVALVULAR STENOSIS IN A YOUNG MAN

Sporadic supravalvular stenosis in a young man

Supravalvar aortic stenosis (SVAS) is a form of congenital left ventricular outflow tract (LVOT) obstruction that occurs Wooden decor as a localized or diffuse narrowing of the ascending aorta beyond the superior margin of the sinuses of Valsalva.SVAS is a rare progressive congenital heart defect with a higher risk of sudden cardiac death.Our patie

Spatial Information Enhancement with Multi-Scale Feature Aggregation for Long-Range Object and Small Reflective Area Object Detection from Point Cloud

Accurate and comprehensive 3D objects detection is important for perception systems in autonomous driving.Nevertheless, contemporary mainstream methods tend to perform more effectively on large objects in regions proximate to the LiDAR, leaving limited exploration of long-range objects and small objects.The divergent point pattern of LiDAR, which r

Dynamics on semi-discrete Mackey-Glass model

Red blood cells play an extremely important role in human metabolism, and the study of hematopoietic models is of Sideboards great significance in biology and medicine.A kind of semi-discrete hetmatopoietic model named Mackey-Glass Model was proposed and analyzed in this paper.The existences, stabilities, and local dynamics of the fixed points were

Differentiation ability of hematopoietic stem cells and mesenchymal stem cells isolated from human peripheral blood

Human hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs) are the major stem cells of the bone marrow and are usually isolated from the peripheral blood.In the present study, we isolated these stem cells by an apheresis method from a donor who was administered granulocyte colony-stimulating factor (G-CSF).In vitro propagation of ESSEN
