A large number of nuclear-encoded proteins are imported into chloroplasts after they are translated in the cytosol. Import is mediated by transit peptides (TPs) at the N termini of these proteins. TPs contain many small motifs, each of which is critical for a specific step in the process of chloroplast protein import; however, it remains unknown how these motifs are organized to give rise to TP...

Trehalose in ectoderms functions in energy metabolism and protection in extreme environmental conditions. We structurally characterized trehalose 6-phosphate synthase (TPS) from hemocytes of the blue crab, Callinectes sapidus. C. sapidus Hemo TPS (CasHemoTPS), like insect TPS, encodes both TPS and trehalose phosphate phosphatase domains. Trehalose seems to be a major sugar, as it shows higher l...

Für die Navigation in laparoskopischer Leberchirurgie ist die Registrierung präoperativer Daten das zentrale Problem. Es wird das Konzept und die Umsetzung vorgestellt. Dabei kommt ausschließlich eine elektromagnetisch navigierte laparoskopische Ultraschallsonde zum Einsatz. Die Registrierung besteht aus drei Schritten: Einer Vorregistrierung basierend auf grob geschätzten Punkten an der Lebero...

Trehalose is the major blood sugar in insects. Physiological significance of this compound has been extensively reported. Trehalose-6-phosphate synthase (TPS) is an important enzyme in the trehalose biosynthesis pathway. Full-length cDNAs of TPS (Of tps) and its alternative splicing isoform (Of tps_isoformI) were cloned from the Asian corn borer (ACB), Ostrinia furnacalis (Guenée; Lepidoptera: ...

Background. Transpancreatic precut sphincterotomy (TPS) is an option for difficult common bile duct (CBD) access, and the reports are few, with immediate success rate varying from 60 to 96%. The description of relation between the size of TPS and the immediate success rate of CBD cannulation was not found in the literature. The Aim of the Study. To evaluate the relation of large TPS to immediat...
