Körperliche Funktionsfähigkeit, Allgemeinbefinden und Zufriedenheit mit Tiotropium/Olodaterol im Behandlungsalltag von COPD-Patienten in Deutschland

<p>Assessment of physical functioning and handling of tiotropium/olodaterol Respimat® in patients with COPD in a real-world clinical setting</p>

Background Patients with chronic obstructive pulmonary disease (COPD) show signs of reduced physical activity from the early stages of the disease, impacting morbidity and mortality. Data suggest treatment with tiotropium, a long-acting muscarinic antagonist, and olodaterol, a long-acting s2-agonist (LABA), as monotherapies and in combination, increases exercise capacity. This study assessed the effects of fixed-dose tiotropium/olodaterol (delivered via Respimat®) on physical function in Global Initiative for Chronic Obstructive Lung Disease A-D patients requiring long-acting dual bronchodilation treatment in a real-world setting. Methods This open-label, single arm, noninterventional study…

Characterization of the cleavage site and function of resulting cleavage fragments after limited proteolysis of Clostridium difficile toxin B (TcdB) by host cells

Clostridium difficiletoxin B (TcdB) is a single-stranded protein consisting of a C-terminal domain responsible for binding to the host cell membrane, a middle part involved in internalization, and the N-terminal catalytic (toxic) part. This study shows that TcdB is processed by a single proteolytic step which cleaves TcdB10463between Leu543and Gly544and the naturally occurring variant TcdB8864between Leu544and Gly545. The cleavage occurs at neutral pH and is catalysed by a pepstatin-sensitive protease localized in the cytoplasm and on the cytoplasmic face of intracellular membranes. The smaller N-terminal cleavage products [63 121 Da (TcdB10463) and 62 761 Da (TcdB8864)] harbour the cytotox…
