The truth depends on the usefulness
No full textFake News, Manipulation und Propaganda verweisen in den Netzen der globalen Wissens- und Informationsgesellschaft auf grundlegende Mechanismen der sozialen Reproduktion. Denn das Internet markiert eine entscheidende Wahlmöglichkeit zwischen dem Wahren und dem Falschen. Desinformation und Manipulation erscheinen dabei als legitime Mittel der politischen Kommunikation, in der es mehr und mehr darum geht, die Nützlichkeit einer gegebenen Information zu bestimmen. Zwischen normativen Bildungsvorstellungen und informellen Handlungspraktiken eröffnet sich mithin auch ein Raum, in dem Wahrheit und Lüge auf dem Spiel stehen. Abschließend konkretisiert der Autor seine Thesen mit einem einfachen (und medienpädagogisch einfach umsetzbaren) Anwendungsbeispiel für den Schulunterricht.Fake news, manipulation and propaganda point to fundamental mechanisms of social reproduction in the networks of the global knowledge and information society. Because the Internet marks a crucial choice between the true and the false. Disinformation and manipulation appear as legitimate means of political communication, in which it is more and more important to determine the usefulness of a given information. Between normative educational conceptions and informal practices, a space opens where truth and lies are at stake. Finally, the author concretizes his theses with a simple (and media-educationally easy to apply) application example for school lessons
Lowest detection limit (LOD) of cholera RLDT for environmental water samples.
No full textEnvironmental water samples were spiked with ten-fold serial dilutions of V. cholerae N16961 and processed and tested with an RLDT kit. LOD was determined. A: O1rfb gene; B: ctxA gene.</p
Lowest Detection Limit (LOD) of cholera RLDT from dried stool on filter paper.
No full textStool samples were spiked with ten-fold serial dilutions of V. cholerae N16961and 50 uL of each dilution was spotted on filter paper. The stool spots were processed and tested with an RLDT kit. LOD was determined. A: O1rfb gene; B: ctxA gene.</p
Lowest detection limit (LOD) of cholera RLDT tested directly from the stool.
No full textStool samples were spiked with ten-fold serial dilutions of V. cholerae N16961. The spiked stool samples were processed and tested with the RLDT kit. LOD was determined as the lowest concentration at which the target gene was detected in all ten runs. A: O1rfb gene; B: ctxA gene.</p

No full textEarly repolarization pattern as a predictor of atrial fibrillation recurrence following radiofrequency pulmonary vein isolation
No full textBackground Early repolarization patterns (ERP) have been found to be associated with poor cardiovascular end points. We aimed to evaluate the ERP prevalence among patients with structurally normal hearts undergoing radiofrequency (RF) pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (AF) ablation and its association with the AF recurrence. Methods All consecutive patients who underwent RF-PVI as index procedure for paroxysmal AF in our center were evaluated. Exclusion criteria: structural heart disease, ongoing use of Class I/III antiarrhythmics, complete-bundle-branch-block. Lateral (I, aVL, V-5-V-6), inferior (II, III, aVF), or infero-lateral (both) ERP were defined in baseline ECG as horizontal/downsloping J-point elevation >= 1 mm in two consecutive leads with QRS slurring/notching. Documented episodes of AF lasting >= 30 s were considered recurrence. Results Of 701 cases, 434 patients (305 males, 58 +/- 11 years) were included for analysis. ERP observed in 67 patients (15.4%) (Infero-lateral n = 26, inferior n = 23, lateral n = 18) which were significantly younger, demonstrating longer PR-interval and lower heart rates. At a mean follow-up of 22.1 +/- 9.7 months, AF recurrences were found in 107 patients (24.6%). In middle-aged patients (>= 40-n = 206, 79% male), those with an infero-lateral ERP had higher recurrence compared with the ones without (56.3% vs. 19%; p = 0.002). Infero-lateral ERP was significantly predicting recurrence (HR 2.42, 95% CI 1.21-4.82; p = 0.01). Conclusion Early repolarization patterns was more prevalent in our AF population than in the general population. Infero-lateral ERP in baseline ECG might predict AF recurrence in the follow-up after RF-PVI in middle-aged patients
