PTX3 Polymorphisms and Invasive Mold Infections After Solid Organ Transplant
Donor PTX3 polymorphisms were shown to influence the risk of invasive aspergillosis among hematopoietic stem cell transplant recipients. Here, we show that PTX3 polymorphisms are independent risk factors for invasive mold infections among 1101 solid organ transplant recipients, thereby strengthening their role in mold infection pathogenesis and patients' risk stratificatio
<Session 6: Wildlife Tracking II>Methodological challenges for studying penguins eco-physiology in remote environments
19–22 May 2022 Kyoto, JapanHigher vertebrates situated at the top of food chains are often used as bio-indicators to provide information about the health of their ecosystem. Penguins are one of these species of interest, but the harsh environments they live in, as well as their pelagic lifestyle, make the development and deployment of adequate instrumentation challenging; moreover, these animals have a long lifespan that allows for long term eco-physiological and population dynamics studies but also causes additional technical difficulties. To address these limitations several techniques must be combined. First, since observed individuals live in dense colonies, Radio Frequency Identification by means of passive implantable tags provides a reliable and long lasting solution to monitor individuals while using automatic detection systems placed at strategic locations in the field. In parallel, physiology and behaviors (including long-distance swimming and deep diving activities) of penguins can be recorded for weeks or months using bio-logger attached to the feathers, and up to three years with surgically implanted devices. For most cases, recapture of the animals is necessary to retrieve the data. Yet, devices combining bio-logging and telemetric functions have been recently developed to allow periodical downloading of the data when animals come back to their colony

Self-congruity theory: to what extent does it hold in tourism?
This paper investigates (1) if, and to what extent, self-congruity theory is applicable in tourism, (2) to what extent travel and person characteristics explain the degree of self-congruity, and (3) how the operationalization of self-congruity affects the conclusions about whether self-congruity holds in tourism. Results derived from a large-scale study of Swiss travelers indicate that conclusions depend heavily on how self-congruity is measured. Using a relatively strict measure, more than half the trips under study can be classified as self-congruent. However, travel and sociodemographic characteristics are very limited in their ability to explain when self-congruity occurs
Gas chromatography at the Tritium Laboratory Karlsruhe
Among the analytical techniques (mass spectrometry, laser Raman spectroscopy, gas chromatography, use of ionisation chambers) employed at the Tritium Laboratory Karlsruhe (TLK), gas chromatography plays a prominent role. The main reasons for that are the simplicity of the gas chromatographic separation process, the small space required for the equipment, the low investment costs in comparison to other methods, the robustness of the equipment, the simple and straightforward analysis and the fact that all gas species of interest (with the exception of water) can easily be detected by gas chromatographic means. The conventional gas chromatographs GC1 and GC2 used in the Tritium Measurement Techniques (TMT) System of the TLK and the gas chromatograph GC3 of the experiment CAPER are presented in detail, by discussing their flow diagrams, their major components, the chromatograms measured by means of various detectors, shortcomings and possible improvements. One of the main disadvantages of the conventional gas chromatography is the long retention times required for the analysis of hydrogen gas mixtures. To overcome this disadvantage, micro gas chromatography for hydrogen analysis was developed. Reduction of the retention times by one order of magnitude was achieved.
