Development of antibody immuno-PET/SPECT radiopharmaceuticals for imaging of oncological disorders University of Antwerp
Positron emission tomography (PET) and single-photon emission computed tomography (SPECT) are molecular imaging strategies that typically use radioactively labeled ligands to selectively visualize molecular targets. The nanomolar sensitivity of PET and SPECT combined with the high specificity and affinity of monoclonal antibodies have shown great potential in oncology imaging. Over the past decades a wide range of radio-isotopes have been ...
Hydraulic redistribution of foliar absorbed water causes turgor-driven growth in mangrove seedlings Ghent University
Although foliar water uptake (FWU) has been shown in mature Avicennia marina trees, the importance for its seedlings remains largely unknown. A series of experiments were therefore performed using artificial rainfall events in a greenhouse environment to assess the ecological implications of FWU in A. marina seedlings. One-hour artificial rainfall events resulted in an increased leaf water potential, a reversed sap flow, and a rapid diameter ...
Zinc and arsenic toxicity to plants: an assessment of availability and a risk estimate in mining impacted soils KU Leuven
Research summary "Diagnosing metal bioavailability in metal mine waste contaminated soils" The diagnosis of risk in the contaminated land, and, hence the decision for site clean-up, can certainly not only be based onthe total soil metal concentration. Metals in mine-impacted soils are often present in the primary minerals that are sparingly soluble and available to soil organisms. It is also well established that soil properties, notably pH, ...
Different glassmaking technologies in the production of Iron Age black glass from Italy and Slovakia KU Leuven
This study presents the results of an archaeometrical investigation performed on 75 black glass beads dated to the ninth–fifth century BC coming from Bologna, Cumae, and Pozzuoli (Italy), and Chotin (Slovakia). The analyses of the major, minor, and trace elements—as well as that of Sr and Nd isotopes performed on a selection of samples coming from Bologna—provided evidence for two different production technologies in Iron Age black glass found ...
Foliar uptake of radiocesium from irrigation water by paddy rice (Oryza sativa): an overlooked pathway in contaminated environments KU Leuven
Flooded (paddy) rice (Oryza sativa) can take up ions from the irrigation water by foliar uptake via the exposed stem base. We hypothesised that the stem base uptake of radiocaesium (RCs) is a pathway for rice grown in RCs-contaminated environments. We developed a bi-compartmental device which discriminates the stem base from root RCs uptake from solutions, thereby using RCs isotopes (137 Cs and 134 Cs) with < 2% solution leak between the ...
Diagnostic set-up and modelling for investigation of synergy between 3D edge physics and plasma-wall interactions on Wendelstein 7-X Ghent University
A group of edge diagnostics and modelling has been developed for investigation of synergy between 3D edge physics and plasma-wall interactions on Wendelstein 7-X (W7-X). Two endoscopes have been designed for visible and ultraviolet spectroscopy and tomography of the plasma edge, along with infrared thermography of the divertor tiles. 2D profiles of impurities (e.g. helium, carbon) will be measured by two endoscopes viewing the island divertor ...
Geochemical transect through a travertine mount: A detailed record of CO2-enriched fluid leakage from Late Pleistocene to present-day e Little Grand Wash fault (Utah, USA) KU Leuven
© 2016 Elsevier Ltd and INQUA Active and fossil endogenic travertine mounts scattered along the Little Grand Wash fault are studied as records of Quaternary CO2-enriched fluid leakage. This study focusses on a particular area where a fossil mount formed in a near-surface setting by successive circulation/sealing episodes from Late Pleistocene to Mid-Holocene and where a modern surface travertine is still being formed by a CO2-enriched fluid ...
