This study aimed to develop a novel radiotracer using trastuzumab and the long-lived [52Mn]Mn isotope for HER2-targeted therapy selection monitoring. A new Mn(II) chelator, BPPA, synthesized from rigid bispyclen platform possessing picolinate pendant arm, formed stable inert complex with favorable relaxation properties. BPPA was converted into bifunctional chelator (BFC), conjugated trastuzumab, labeled isotope. In comparison DOTA-GA-trastuzumab, BPPA-trastuzumab conjugate exhibits labeling...
In this study, atmospheric particulate matter (APM) pollution was compared in urban background sites of two cities Hungary—namely the capital Budapest and Debrecen—by analyzing daily aerosol samples collected between 8 December 2009 18 March 2010. Concentration, elemental composition, including BC, sources fine (PM2.5) coarse (PM2.5–10) pollution, as well their variation due to meteorological conditions anthropogenic activities, were determined for both cities. The average PM2.5...
Among humanized monoclonal antibodies, bevacizumab specifically binds to vascular endothelial growth factor A (VEGF-A). VEGF-A is an overexpressed biomarker in cervix carcinoma and involved the development maintenance of tumor-associated neo-angiogenesis. The non-invasive positron emission tomography using radiolabeled target-specific antibodies (immuno-PET) provides longitudinal quantitative assessment tumor target expression. Due having a long-circulating time, radioactive metal ions...
Abstract In this study, the identification of PM sources during smog episodes in Debrecen is presented. The were characterized by high concentration 10 , and linked to a thermal inversion period November 2011 Hungary, when an anticyclone occurred across Europe. 2.5 coarse identified positive matrix factorization (PMF). Additionally, source locations explored using conditional probability function (CPF). A numerical weather prediction model (WRF) was also applied evaluate air pollution...
Abstract In this study, atmospheric aerosol concentration levels in two schools (a primary and a secondary grammar) kindergarten were investigated. The selected institutions are located close to the center of Debrecen, where traffic density is rather high. Coarse fine mass concentrations (PM), elemental composition size distributions determined microenvironments. These different classrooms, school yards, gymnasiums, computer lab, chemical lab so‐called salt room. (for Z ≥ 13) was by PIXE....
Abstract The P‐type ATPase CrpA is an important Cu 2+ /Cd pump in the Aspergilli, significantly contributing to heavy metal stress tolerance of these ascomycetous fungi. As expected, deletion crpA resulted ‐sensitive phenotypes Aspergillus nidulans on agar plates inoculated with conidia. Nevertheless, paradoxical growth stimulations were observed Δ strain both standard plate experiments and cellophane colony harvest (CCH) cultures, when exposed Cd . These observations reflect efficient...
In this case study, we investigate the building infiltration rate and indoor aerosol concentration levels in two buildings equipped with passive house technology one "conventional" Ócsa, Hungary. We have aimed to determine pollution level its elemental composition, establish relationship between outdoor levels, study how different ventilation rates modes affect particulate matter (PM) contamination. Our results indicate that measured PM were well below recommended limits overall. particular,...
This study, conducted in Debrecen, Hungary, aimed to analyse atmospheric particulate matter (APM or PM) through radiocarbon and PIXE analyses during the winter smog (23-25 January) spring (15-18 May) seasons. The information presented this pilot study aims provide insight into importance of utilising detailed characteristics mass size distributions fossil carbon (f

A comparison is given about the effects of low and high current density proton irradiations on surface topography poly(tetrafluoroethylene). 1 MeV beam was used for experiments with 10 8 pA/mm 2 densities.For irradiations, micro-focused, while it highly under-focused.The applied ion fluences were 0.1-1000 nC/mm (6.24 × -6.24 14 ion/cm ).Differential interference contrast microscopy, profilometry, scanning electron microscopy to investigate changes morphology.It found that at etched similarly...
In this case study, aerosol pollution and passenger exposure were investigated while travelling on different public transport vehicles in Hungary. Two sampling campaigns carried out: one autumn 2012 the other spring 2014. Concentration, elemental composition size distribution of samples determined order to characterize atmospheric particulate matter (APM) inside vehicles. The concentration PMcoarse fraction varied between 29 354 μg m−3, PM2.5 concentrations found be 12 192 m−3. This was...
