11. A correlation of NK cytolitic test and BLT esterase test in determining activity of NK cells, stimulated by tumor target cellsAlojz Ihan, 1999, original scientific article Abstract: We examined the granule exocytosis in natural killer (NK) cells by measuring N-benzyloxycarboxy-L-lysine esterase activity. As a source of NK cells we usedbuffy-coat isolated NK cells or peripheral blood lymphocytes (PBL). The exocytosis was triggered by incubating cells with ionomycin/PMA or by NK cell susceptible tumour target cells K562. When we stimulated purified NK cells with tumour target cells, a close correlation (Corr=0.84) of cytolitic NK testresults and BLT test results was obtained. We may conclude that BLT test can provide a valuable tool to discriminate further NK cell deficiency in patients with low cytolitic NK test results.

12. Flow cytometric pitfalls in immunophenotyping of lymphomasAlojz Ihan, 1998, review article Abstract: Flow cytometry has been introduced as the most reliable method for the analysis of lymphocyte subsets. The advantage of flow cytometry is that it enables application of virtually all monoclonal antibodies (native cells), a quantitative estimation of different lymphoid cells, and that cell can be simultaneously analysed for multiple marker expression. The usage of flow cytometers requiers considerable knowledge of physics and its technical application. Moreover, several problems arise from the complexity of the biolocal systems investigated.

15. Using Ground Penetrating Radar (GPR) for detecting a crypt beneath a paved church floorMarjana Zajc, Alojzij Grebenc, 2023, original scientific article Abstract: After the discovery of an archive document regarding an underground crypt beneath the f loors of the Church of St. Margaret (Sv. Marjeta) in Dol pri Ljubljani, Slovenia, further research was carried out to confirm its presence. An area filled with construction waste was discovered during a recent small-scale renovation of the church floor. This finding suggested the potential underground chamber may have been partly filled in during one of the previous restorations. A non-invasive GPR study was carried out along eight profiles inside the church to prove the existence of an underground crypt. Results show the presence of an air-filled chamber, confirmed later by a hole drilled in the floor. Additional findings in the church archive and pictures taken by a camera, lowered through a drilled hole, revealed three previously unknown caskets in the crypt. According to the archives, two of them belong to Baron Wolf Daniel Erberg and his wife who died in 1783 and 1774, respectively.
