Defects in yttrium aluminium perovskite and garnet crystals: atomistic study

2000

Native and impurity point defects in both yttrium aluminium perovskite (YAP) and garnet (YAG) crystals are studied in the framework of the pair-potential approximation coupled with the shell model description of the lattice ions. The calculated formation energies for native defects suggest that the antisite disorder is preferred over the Frenkel and Schottky-like disorder in both YAP and YAG. The calculated values of the distortion caused by the antisite YAl x in the lattice turn out to be in an excellent agreement with the EXAFS measurements. In non-stoichiometric compounds, the calculated reaction energies indicate that excess Y2 O3 or Al2 O3 is most likely to be accommodated by the forma…

Analysis of relapse after transplantation in acute leukemia: A comparative on second allogeneic hematopoietic cell transplantation and donor lymphocy…

2018

Relapse of acute leukemia (AL) after allogeneic hematopoietic cell transplantation (Allo-HCT) entails a dismal prognosis. In this scenario, donor lymphocyte infusions (DLIs) and second Allo-HCT are two major approaches. We compared outcomes of AL patients treated for relapse with DLI or second Allo-HCT after receiving debulking therapy. In total, 46 patients were included in the study; 30 (65%) had acute myeloid leukemia and 16 (35%) had acute lymphoblastic leukemia. The median age was 38 years (range 4-66). Twenty-seven patients received a second Allo-HCT and 19 patients received DLI. The median follow-up of the cohort was 273 days (range 9-7013). Overall survival (OS), disease-free surviv…

Association between physical, psychological and social frailty and health-related quality of life among older people

2019

Abstract Background Studies on the association between frailty and health-related quality of life (HRQoL) are scarce and show contradictory results. This study aimed to evaluate the association between physical, psychological and social frailty and HRQoL among community-dwelling older people. Methods A cross-sectional study was performed with baseline data collected in 2015 from the Urban Health Centers Europe (UHCE) project in five European countries, the United Kingdom, Greece, Croatia, The Netherlands and Spain. A total of 2325 participants were included in the baseline measurements of the Urban Health Centers Europe project; 2167 participants (mean age = 79.7; SD=5.6) were included in t…

Humanized mice in cutaneous leishmaniasis—Suitability analysis of human PBMC transfer into immunodeficient mice

2019

Humanized mice represent a suitable preclinical test system for example therapeutic interventions in various disease settings, including infections. Here, we intended to establish such system for cutaneous leishmaniasis by infecting T, B and NK cell-deficient mice adoptively transferred with human peripheral blood mononuclear cells (PBMC). L major infection led to the establishment of parasite lesions harbouring viable parasites and human T cells, but parasite elimination was not seen due to a species-specific activity of T cell-derived human IFNγ. In addition, up to 50% of infected mice succumbed to severe graft-versus-host disease. In summary, even though long-term disease outcome assessm…

Composition of mosses, their metabolites and environmental stress impacts

2018

Sūnas ir nozīmīga augu grupa ar plašu izplatību. Sūnu sastāva pētījumi ir kļuvuši aktuāli, ņemot vērā bioloģiski aktīvu savienojumu klātbūtni un augsto izturību pret vides apstākļu mainību. Promocijas darba mērķis ir analizēt sūnu sastāvu, to metabolītus un vides stresa ietekmes uz tiem. Veikta sūnu sekundāro metabolītu ekstrakcijas apstākļu izpēte, kas nodrošina liela skaita vielu identifikāciju. Sūnu lipīdi satur daudzas bioloģiski aktīvas vielas un veikta to aktivitātes izpēte. Sūnu sekundārie metabolīti uzrāda augstu antimikrobiālo aktivitāti un spējas inhibēt vairāku vēža šūnu līniju attīstību un līdz ar to satur perspektīvas vielu grupas izmantošanai biomedicīnā. Vides stresa ietekmes…

Virtuālās kopienas sajūta: Facebook domubiedru grupas "Vegan Latvia" gadījums

2021

Bakalaura darba temats ir “Virtuālās kopienas sajūta: Facebook domubiedru grupas “Vegan Latvia” piemērs”. Darba mērķis ir noskaidrot kā virtuālās kopienas sajūtas teorētiskā perspektīva ir pielīdzināma Facebook domubiedru grupas “Vegan Latvia” biedriem un vai virtuālās kopienas sajūta ir saistīta ar indivīda ikdienas praksēm vegāniskā dzīvesveidā. Lai sasniegtu izvirzīto mērķi, autore veic teorētisku materiālu izpēti un ar tiešsaistes aptaujas anketām iegūst empīriskus datus. Darbā tiek secināts, ka virtuālās kopienas sajūta ir saistīta ar vērtību internalizāciju un indivīda ikdienas praksēm vegāniskā dzīvesveidā.

Evaluación del uso de un EVS y de mUVies en las aulas: una visión del profesorado y del alumnado

2019

[ES] La utilización de las Tecnologías de la Información y la Comunicación (TICs) y de las diferentes metodologías docentes innovadoras, que han hecho su aparición en un alto porcentaje de las materias que componen los actuales planes de estudio, ha resultado de gran ayuda en el proceso de autoaprendizaje del alumnado. Este es el caso de una asignatura de carácter cuantitativo del grado en Finanzas y Contabilidad de la Universitat de València. En el trabajo que se presenta, se expone, para el caso de dicha materia, la visión de cada uno de los agentes implicados en el proceso de enseñanza-aprendizaje respecto al uso de un “electronic voting system” (EVS), los clickers, y de vídeos de apoyo …
