PURPOSE It is essential to evaluate new stent designs before in vivo testing. The purpose of this study was to develop and validate a controlled and reproducible patient-derived process to produce a life-size in vitro model of aortic arch aneurysm for endovascular procedure simulation. METHODS A three-dimensional magnetic resonance angiography (3D MRA) image derived from a 60-year-old patient...

Problem statement. The integration of the latest technologies in field software at stages construction appears as one main tasks for designers. Creating objects based on 3D printing technology requires use appropriate high-tech solutions. One these solutions is analysis converting process a three-dimensional model into control code − it precisely from this that degree efficiency building struct...

Pelvic pain due to chronic pudendal nerve (PN) compression, when treated surgically, is approached with a transgluteal division of the sacrotuberous ligament (STL). Controversy exists as to whether the STL heals spontaneously or requires grafting. Therefore, the aim of this study was to determine how surgically divided and unrepaired STL heal. A retrospective evaluation of 10 patients who had h...

The sulphotransferase (SULT) gene family is involved with the conjugation of many small drugs, xenobiotics and endogenous compounds. In this report, we describe the cloning and expression of novel cDNAs from human and rat brain, which are structurally related to the SULTs. These cDNAs have been termed 'brain sulphotransferase-like' (BR-STL), because of their similarity to the SULTs and their se...

Streptolydigin (Stl) is a potent inhibitor of bacterial RNA polymerases (RNAPs). The 2.4 A resolution structure of the Thermus thermophilus RNAP-Stl complex showed that, in full agreement with the available genetic data, the inhibitor binding site is located 20 A away from the RNAP active site and encompasses the bridge helix and the trigger loop, two elements that are considered to be crucial ...

In our previous work we have introduced the logic STL*, an extension of Signal Temporal Logic (STL) that allows value freezing. In this paper, we define robustness measures for STL* by adapting the robustness measures previously introduced for Metric Temporal Logic (MTL). Furthermore, we present an algorithm for STL* robustness computation, which is implemented in the tool Parasim. Application ...

Some applications use data formats (for example STL file format), where a set of triangles is used to represent a surface of an object and it is necessary to reconstruct the regular triangular mesh from such a data format for many applications. It is a lengthy process for large data sets as the time complexity of this process is O(N) or O(N lgN), where N is a number of triangles. Hash data stru...

Ovarian follicle formation in Drosophila melanogaster requires stall (stl) gene function, both within and outside the ovary, for follicle individualization, stalk cell intercalation, and oocyte localization. We have identified the stl transcript as CG3622, and confirmed the presence of three alternatively spliced isoforms, contrary to current genome annotation. Here we show that the gene is exp...
