Vaccinium s.p.p. ogu spiedpalieku ekstraktu acetilholīnesterāzes inhibīcija in vitro
2019
Vaccinium spp. ogas un to produkti tiek aktīvi pētīti pēdējo 10 gadu laikā. Tiem ir pierādīts kognīciju uzlabojošs efekts in vivo. Pēta arī ogu spiedpalieku aktīvo vielu sastāvu un ietekmi uz organismu. Darbā ir analizēti melleņu, krūmmelleņu, dzērveņu, purva dzērveņu un brūkleņu spiedpalieku ekstraktu efekti uz AchE aktivitāti in vitro, kā arī mijiedarbība ar AChE inhibitoriem – ipidakrīnu, donepezilu un neostigmīnu. AChE aktivitāte mērīta ar spektroskopisko Ellmana metodi. Iegūtie dati liecina, ka visi ekstrakti no koncentrācijas atkarīgā veidā inhibē AChE. Dzērveņu, purva dzērveņu, krūmemelleņu un brūkleņu ekstrakti potencē AChE inhibitorus, taču melleņu ekstrakts potencē tikai neostigmī…
Mortality by age, gene and gender in carriers of pathogenic mismatch repair gene variants receiving surveillance for early cancer diagnosis and treat…
2023
Background: The Prospective Lynch Syndrome Database (PLSD) collates information on carriers of pathogenic or likely pathogenic MMR variants (path_MMR) who are receiving medical follow-up, including colonoscopy surveillance, which aims to the achieve early diagnosis and treatment of cancers. Here we use the most recent PLSD cohort that is larger and has wider geographical representation than previous versions, allowing us to present mortality as an outcome, and median ages at cancer diagnoses for the first time.Methods: The PLSD is a prospective observational study without a control group that was designed in 2012 and updated up to October 2022. Data for 8500 carriers of path_MMR variants fr…
En kvinnelig toppidrettsutøvers refleksjoner over egen karriere : håndtering av med- og motgang i idrettskarrieren belyst gjennom forståelse av hvord…

Masteroppgave i idrettsvitenskap - Universitetet i Agder 2016 Title A Top Female Athlete's Reflection on her Career - Dealing with adversity in a sports career illustrated through the understanding of how motivation and coping skills can help to overcome career obstacles. Project Background Many athletes, especially women, feel they lose the motivation for playing sports early on in their careers. There is a need for more knowledge regarding coping capabilities in the face of decreasing motivation to continue a sports career. Purpose and problem There is a need to understand how women who have experienced hardship but still chose to continue with their sport, think about coping mechanisms w…

From microbial proteomics to synthetic biology: Amycolatopsis balhimycina case
2012
Actinomycetes, filamentous Gram-positive bacteria, are usually exploited as bio-farms naturally producing a wide range of small biologically active metabolites, such as antibiotics, extensively used in medicine, food-industry, chemistry and bio-remediation strategies. The development of high throughput technologies, like proteomics, allows functional genomic studies aimed at shedding light on molecular mechanisms controlling the production of useful compounds and macromolecules. Differential proteomic analyses, performed by using Two Dimensional PolyAcrylamide Gel Electrophoresis (2D-PAGE) coupled to mass spectrometry (MS) procedures, revealed novel links between balhimycin production (a va…
High-resolution orthophoto map and digital surface models of the largest Argentine Islands (the Antarctic) from unmanned aerial vehicle photogrammetry
2020
This study presents the first high-resolution orthophoto maps and digital surface models (DSMs) of the largest Argentine Islands, West Antarctica. Aerial surveys with small unmanned aerial vehicle (UAV) were performed in Austral summer, 2018, taking 10,041 aerial photographs. Accuracy requirements were ensured using ground control points (GCPs). A resolution of 3.4 and 6.8 cm/px of orthomosaics and DSMs is reached on average, and the RMS reprojection error is 0.22 m on average. We report the morphometric parameters of surveyed islands and discuss issues related to accuracy and the usage of UAVs in polar conditions. This study demonstrates that small and low cost UAVs can be successfully use…
The cell nucleus. A study in Burgundy
2019
ABSTRACT Wilhelm Bernhard’s revolutionary microscopy techniques helped him put forward the hypothesis of specialized compartmentalization of the nucleus. He also described for the first time the nuclear bodies and peri-chromatin fibrils, and demonstrated that these granules contain an RNA component. The tradition of biennial workshops, named after this great scientist, continues, and this year it took place in the heart of Burgundy, in Dijon, France (May 20–24, 2019, organized by INSERM UMR1231, UBFC), where well-fed participants emphasized the importance of viewing the cell nucleus as a hub of specialized colloidal compartments that orchestrate replication, transcription and nuclear transp…

Design and development of safety and control systems in ATLAS
2021
El gran colisionador de hadrones, o LHC, es el acelerador de partículas más grande y potente del mundo. Ha sido construido por el CERN, la Organización Europea para la Investigación Nuclear, entre 1998 y 2008 en Ginebra, Suiza. Sucesivas mejoras en el LHC supondrán a partir de mediados del 2027 un incremento de la luminosidad, cuando pasará a llamarse High Luminosity LHC (HL-LHC). Esta tesis se divide en dos partes, por una parte la seguridad y operación de la infraestructura y por otra los sistemas de control y toma de datos. La primera parte de la tesis se dedica a la seguridad y operación de la infraestructura. Después de más de 10 años de funcionamiento, el riesgo de posibles fallos en …
Search for pair production of first or second generation leptoquarks in proton-proton collisions at sqrt(s)=7 TeV using the ATLAS detector at the LHC
2011
This paper describes searches for the pair production of first or second generation scalar leptoquarks using 35 pb−1 of proton-proton collision data recorded by the ATLAS detector at √s=7 TeV. Leptoquarks are searched in events with two oppositely-charged muons or electrons and at least two jets, and in events with one muon or electron, missing transverse momentum and at least two jets. After event selection, the observed yields are consistent with the predicted backgrounds. Leptoquark production is excluded at the 95% CL for masses MLQ<376 (319) GeV and MLQ<422 (362) GeV for first and second generation scalar leptoquarks, respectively, when assuming the branching fraction of a leptoquark…
