Autoantikūniai ant šunų eritrocitų ir trombocitų: nustatymas ir funkcinė svarba / Auto-antibodies on canine erythrocytes and platelets: detection and functional significance

Kučinskienė, Gintarė 30 December 2005 (has links)
In this study, we demonstrated that membrane immunofluorescence (MIF) with canine erythrocytes is a much more sensitive diagnostic technique compared with the Coombs test to detect auto-antibodies on RBC. We also demonstrate how the evaluation of the MIF test can be made more precisely which results in a more clear interpretation. Till nowadays the Evans syndrome (combined thrombocytopenia and anemia) is not very well diagnosed in dogs. Only a few studies with low animal numbers tested auto-antibodies on RBC and thrombocytes. Here we describe the frequency of Evans syndrome based on the evaluation of a large data set with 557 dogs. The novelty of the thesis also lies in making a research of the amount of CICs in sera of AIHA/AITP patients is described as well as the cytotoxic potential of patient’s sera for canine leucocytes. These new aspects of diagnosis (AIHA) and pathogenesis (AIHA/AITP) are not only relevant for dogs but also for humans and can be used for better differential diagnosis in medicine. The new findings with respect to circulating immune complexes and cytotoxicity are also offer new therapeutic concepts. Besides, the study has resulted in the characterization of monoclonal antibodies which allow for the detection of so far undetectable canine differentiation antigens (CD molecules) on canine erythrocytes (CD235) and thrombocytes (CD42a). The identified mAbs are useful in the identification of relevant target structures for autoantibodies on these cells.

Ekologinių grėsmių įtaka regioninei integracijai / The impact of environmental threats on regional integration

Pikšrytė, Aistė 23 June 2014 (has links)
Magistro darbo problema yra susijusi su situacija, kuomet nedidelė valstybių tarpusavio priklausomybė ir nenoras riboti savo suverenitetą lemia globalių aplinkosauginių režimų neefektyvumą. Tuo tarpu regioninis bendradarbiavimas, sąlygojamas valstybių tarpusavio priklausomybės, leidžia efektyviau spręsti kylančias problemas. Regionai, siejami iniciatyvų įveikti specifines ekologines grėsmes, gali būti ypatingai suinteresuoti bendradarbiauti ir kurti ekologinio saugumo kompleksus. Todėl bendradarbiavimas ekologinėje srityje gali skatinti tolesnę regiono integraciją. Tyrimo objektu darbe laikomas dėl ekologinių grėsmių vykstantis regioninis bendradarbiavimas bei institucionalizuotos jo formos. Darbe keliamas klausimas, kokiomis sąlygomis ekologinės grėsmės skatina regioninį bendradarbiavimą? Taip pat keliamas šalutinis klausimas, kokie faktoriai riboja ekologinio bendradarbiavimo procesus? Tiesioginio ryšio tarp ekologinių grėsmių ir regioninio bendradarbiavimo nėra užfiksuota, o tai leidžia teigti, jog ekologinės grėsmės gali skatinti regioninį bendradarbiavimą tik egzistuojant tam tikroms sąlygoms, kurių identifikavimas ir analizė yra pagrindinis darbo tikslas. Darbe keliama prielaida, kad ekologinės grėsmės skatina regioninį bendradarbiavimą, egzistuojant trims būtinoms sąlygoms: - ekologinės grėsmės regiono valstybių yra suvokiamos kaip gyvybinės; - bendradarbiavimas ekologinėje srityje sukuria potencialą regiono ekonominei plėtrai; - regionas patiria išorės jėgų įtaką...

This fact forms the main problem of the MA thesis. The MA thesis is based on the presumption that regional cooperation which is determined by the interdependence of the states allows to resolve current issues easier. Certain regions which have intentions to cope with common environmental threats may be especially interested in cooperation and establishment of environmental security complexes. Therefore, cooperation may encourage the further integration. The key question of the MA thesis is when and in what circumstances the environmental threats encourage regional integration? The additional question is what factors restrict the processes of regional cooperation on the basis of the environmental threats? The analytical parts encompass the analysis of cases of Nile and Mekong regions. The object of the research is the regional cooperation and its institutionalized forms, as a consequence of the environmental threats. The aim of the analytical parts of the thesis is to examine whether the environmental threats encourage the regional cooperation on three main conditions: - the environmental threats are regarded as existential issues by the states of the certain region; - cooperation in the environmental field creates an opportunity for the economic development of states; - the regions are influenced by the external actors, which...
