Analysis of Exosomal Cargo Provides Accurate Clinical, Histologic and Mutational Information in Non-Small Cell Lung Cancer
2022
Simple Summary Non-small cell lung cancer (NSCLC) is the second most commonly diagnosed cancer and the leading cause of cancer-related death worldwide. Clinical decision-making depends on the histological classification; however, tissue biopsy is frequently not technically feasible due to tumor location or limited tissue samples. Therefore, we propose to find clinical, molecular and histological biomarkers using a minimally invasive approach based on the analysis of the cargo of the blood extracellular vesicles. Exosomes are membranous vesicles present in several biological fluids, which carry biological information to distant tissues, regulating several tumor processes. This study aims to …
A case formulation model for the assessment of psychological problems among deafblind persons
2012
In order to describe and understand possible problems associated with deafblindness we applied a functional analysis case formulation strategy and Functional Analytic Clinical Case Diagrams (FACCD). We collected clinical assessment data from deafblind persons who were experiencing multiple psychological problems as reported by their healthcare professionals. The data were collected after the healthcare professionals were trained in functional analyses and in applying FACCD. The 21 deafblind persons assessed by healthcare professionals were reported to have 3–11 psychological problems. Two case examples are given to illustrate the complexity of a deafblind person's life situation and the fun…
Statistical analysis of the relation between metallic microstructures and mechanical properties
2020
This thesis aims at the development of physical relations between the intricate 3D features of metallic microstructures and the mechanical properties of the material. For understanding which are the microstructural determinants of the resultingmechanical behaviour of metals, a deep quantitative characterisation of the microstructure is needed. The main steps of quantitative characterisation of the microstructures are: identification of the phases distribution and their chemical composition, study of the microstructure morphology (geometrical arrangement of grains, grain boundaries, grain orientations, grain size and grain shape). An accurate description of the microstructure features enrich…
Optical quality of hyperopic and myopic phakic intraocular lenses
2013
Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…
Globālās stereoredzes novērtējums ar anaglifa un polarizēto stereotestu
2019
Bakalaura darbs ir uzrakstīts latviešu valodā uz 34 lapaspusēm. Tas satur 21 attēlu, 5 tabulas, 25 literatūras atsauces. Darba mērķis salīdzināt polarizēto un sarkani-zaļo filtru ietekmi uz stereoredzi, kā arī pievērst uzmanību rezultātu atšķirībai, kas rodas starp polarizēto un anaglifa metodi. Pētījumā tika izmantoti divi stereotesti, polarizētais tests uz Metropsis platformas un datorizēts anaglifa tests, kurš tika izstrādāts ar līdzīgu stimulu un uzdevumiem kā polarizētais tests. Pētījumā piedalījās 49 dalībnieki, kuru uzdevums bija izpildīt abus stereotestus. Tika noskaidrots, ka stereoasums ar polarizētajiem filtriem ir labāks nekā ar sarkani-zaļajiem filtriem. Atslēgas vārdi: stereor…
Gastrointestinal Stromal Tumors (GISTs)
2021
Gastrointestinal stromal tumors (GISTs) are a group of tumors that, over the past 15 years, has emerged from a poorly understood neoplasm to a well-defined tumor entity. GISTs are highly resistant to conventional chemotherapy and, in the past, were typically managed surgically.
Inflammatory response elements, glycan, and proteome profiles as salivary biomarkers for the early diagnosis of OSCC
2021
El cáncer oral, sobre todo el, carcinoma oral de células escamosas (COCE), es la neoplasia maligna más común en la cavidad oral que se caracteriza por un mal pronóstico y una baja tasa de supervivencia, cuando se diagnostica en estadios avanzados. Puede ser tratado de forma efectiva si se detecta en estadios iniciales, mejorando el pronóstico. Por tanto, tras la prevención, el diagnóstico precoz se ha convertido en el principal objetivo en el manejo del cáncer oral, dado su impacto positivo en la supervivencia y calidad de vida de estos pacientes. A menudo, los escasos síntomas iniciales pasan desapercibidos y la enfermedad se descubre en fases avanzadas, por lo que se requiere mejorar el d…
I tumori stromali gastrointestinali: presentazione di sei casi e revisione della letteratura
2005
Gastrointestinal stromal tumours (GISTs) represent the most common kind of mesenchymal tumours that arise from the alimentary tract. GISTs express a growth factor receptor with tyrosine kinase function, which causes cellular proliferation and resistance to apoptosis. GISTs are generally found in the stomach (40-70%), and less commonly in the small intestine, colon-rectum, esophagus and peritoneum. Clinical and instrumental diagnosis is still very difficult to make. Surgery remains the standard treatment for nonmetastatic tumours. For non resectable and metastatic tumours seems to be effective the therapy with Imatinib mesylate, a specific inhibitor of tyrosine kinase receptor (KIT). Are ong…
Can a cheat sheet in an EFL test engage and empower students?
2015
Although occasionally used in language classrooms, cheat-sheet tests have not been explored in foreign or second language education research. This study experimented with cheat-sheet tests in the teaching of EFL in a Finnish upper secondary school. The participants, 101 students, could make a cheat sheet for the grammar part of their English test. A total of 92 students prepared the cheat sheet, nine did not. Students’ cheat sheets, test results and comments constituted the data for this study, analysed both qualitatively and quantitatively. The existence of the cheat sheet and its quality (thorough, good or limited) correlated with the grammar test results: students with a thorough cheat s…
Multiple mini-interviews as a selection tool for initial teacher education admissions
2022
This study investigates the reliability of multiple mini interviews (MMIs) to select students for classroom and special education teacher programs (n = 418) using intraclass correlations and cross-classified multilevel modeling. The results indicated mostly small effects of clustering of applicants to different interviewers and five-station circuits. The largest variance components in the MMI total score were for applicants (63.3%) and measurement error (20.6%), while the variance component for the interviewer was relatively small (11.6–14.4%). The applicants' and interviewers' perceptions were positive. This study provides evidence for the use of MMIs as a reliable tool for initial teacher…
