Shape preservation behavior of a spline consists of criterial conditions for preserving convexity, inflection, collinearity, torsion and coplanarity shapes of data polgonal arc. We present our results which acts as an improvement in the definitions of and provide geometrical insight into each of the above shape preservation criteria. We also investigate the effect of various results from the li...

to be the same. However, since some samples of blood stored in ACDI in the present study did give satisfactory survival results at 35 and 42 days, it has been suggested that red cells of different individuals may vary in their ability to withstand prolonged storage. It should be noted that the purine nucleosides are metabolized to uric acid. While in healthy volunteers the transfusion of450 ml ...

Introduction: Ability to reconstruct the papilla in anterior maxilla is important aspect of perio-plastic surgery. In most articles, connective tissue is used with different designs of incisions. The aim of this study was to use sub-epithelial connective tissue graft (SCTG) with two types of incisions called papilla preservation and semilunar. Materials & Methods: This basic randomized clinica...

Background: Epididymal spermatozoa have been used for production of offspring from genetically important animals after they are dead. To attain optimal fertility with epididymal spermatozoa, they should be preserved in a suitable medium in 37°C. Preservation media provides requirement for spermatozoa and affects its motility, viability, and fertility. Sucrose is one of the important components ...

A modification of the Lecompte operation is reported in which the pulmonary valve is preserved. This technique is applicable in certain anomalies of ventriculoarterial connection with ventricular septal defect and subpulmonary stenosis. The main advantage of this modification, besides preservation of growth potential of the translocated pulmonary artery, consists of preservation of pulmonary va...
