Identification by GC-FID and GC-MS of amino acids, fatty and bile acids in binding media used in works of art.

2001

GC-FID was used as single methodology for the identification and differentiation of proteins, lipids and ox bile from binders used in artistic paintings. The samples were hydrolyzed by HCl. Subsequently, the simultaneous formation of volatile derivatives of the amino, fatty and bile acids with ethyl chloroformate was performed quickly and safely in an aqueous medium. The derivatives were separated by capillary GC and characterized by GC-MS. The ageing of drying oils was studied, identifying pelargonic acid among other degradation products. Proteinaceous and lipoid binding media were characterized by means of the quotients between the areas of the peaks for each amino or fatty acid with resp…

Teknisten ja katsojasta riippuvien tekijöiden vaikutus radiologisten kuvien havainnointiin

2011

Tutkielmassa kartoitettiin katsojan havainnointikyvyn ja näyttöpäätteen kuvanlaadun vaikutuksia kuvanhavainnointiin. Tavoitteena oli selvittää, mitkä tekijät vaikuttavat havainnointitarkkuuteen eniten ja voitaisiinko sitä merkittävästi parantaa teknisin toimenpitein. Kiinnostuksen kohteena oli myös, eroavatko kliinikoiden ja radiologien tulokset toisistaan. Tutkimus toteutettiin Keski-Suomen keskussairaalassa selainpohjaisena kyselytutkimuksena. Katsojan ominaisuuksia selvitettiin taustoittavilla kysymyksillä, näyttöjärjestelmän kuvanlaatua visuaalisilla testeillä ja havainnointitarkkuutta kontrasti-detalji-testeillä. Vastaajia oli 64, joista kliinikkoja 52 ja radiologeja 12. Tuloksista sel…

Dysfunctional High-Density Lipoproteins Are Associated With a Greater Incidence of Acute Coronary Syndrome in a Population at High Cardiovascular Risk

2020

Background: Studies have failed to establish a clear link between high-density lipoprotein (HDL) cholesterol and cardiovascular disease, leading to the hypothesis that the atheroprotective role of HDL lies in its biological activity rather than in its cholesterol content. However, to date, the association between HDL functional characteristics and acute coronary syndrome has not been investigated comprehensively. Methods: We conducted a case-control study nested within the PREDIMED (Prevención con Dieta Mediterránea) cohort, originally a randomized trial in which participants followed a Mediterranean or low-fat diet. Incident acute coronary syndrome cases (N=167) were individually matched …

Estudio de los factores cardiodinámicos en pacientes hipertensos controlados y normotensos durante la exodoncia

2022

Se trata de un estudio prospectivo observacional, de casos y controles realizado en el Hospital Dr. Peset (Valencia), la muestra está constituida por un total de 254 pacientes: 106 controles normotensos (41,7%) y 148 casos hipertensos (58,3%), con una edad de 58,3 ± 18,7 años y un rango entre 14 y 93 años. Las variables hemodinámicas: SO2 (Saturación de Oxigeno), PAS (Presión Arterial Sistólica), PAD (Presión Arterial Diastólica), FC (Frecuencia Cardiaca) y PR (Pulsaciones) se midieron en 4 periodos en la exodoncia, y se registró el nivel de la ansiedad por medio de las escalas: Corah (MDAS), Beck (BAI), y Hamilton. El objetivo general del estudio es valorar las constantes cardiodinámicas y…

Kvalitet på elektronisk sykepleiedokumentasjon hos pasienter med hoftebrudd og helsetjenesteassosiert infeksjon

2019

Masteroppgave klinisk helsevitenskap ME520 - Universitetet i Agder 2019 Project background: Approximately 9000 patients with hip fractures are annually admitted to hospitals (Folkehelseinstituttet, 2016). About 50000 patients receive an annual health-related infectionthat cangive more number of bed nightsand an increasedrisk of mortality. Good infection control procedurescan prevent some of the health related infections (Helse-og omsorgsdepartementet, 2008b). Nursing for these patients consists of a pre-and a postoperative periodwhere observations of signs of complications are important(Knutstad, 2013). Research shows that nursing documentation in several cases is poor, both in relation to …

Tilgangsstyring av elektronisk pasientjournal : en Delphistudie av dagens utfordringer og synliggjøring av potensielle forbedringer

2014

Masteroppgave i helse- og sosialinformatikk HSI 500 Universitetet Agder 2014 In health care, access to sensitive information about patients is a necessity in order to offer care to the patient, and maintain patient safety. At the same time it is important that the information is protected against unauthorized access, to ensure patient privacy. Access control is an essential function in electronic health records (EHR) to maintain the duality between patient safety and patient privacy by ensuring that authorized personnel are allowed access to information they need. However, care processes are often unpredictable, and a number of end users can be involved in treatment across organizational un…

Occurrence of pharmaceuticals in municipal wastewater treatment plants and receiving surface waters in Central and Southern Finland

2016

The presence of five selected pharmaceuticals, four anti-inflammatory drugs, diclofenac, ibuprofen, ketoprofen, naproxen, and an antiepileptic drug carbamazepine, was determined at four municipal wastewater treatment plants (WWTPs) and in the receiving waterway near the city of Jyväskylä, in central Finland and also in the River Vantaa. First, an analytical method was developed including a pretreatment and purification followed by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) in the multiple reaction monitoring mode. The studied pharmaceuticals were detected from influents and effluents of four municipal WWTPs and from surface water of eight locations along the water …

Brief interventions in counselling for nutrition and the prevalence of metabolic syndrome in primary care adult patients

2018

This research i) examined the influence of a brief nutrition-based intervention among primary care patients in changing nutrition and clinical values related to metabolic syndrome (study 1), and ii) assessed nutrition and the prevalence of metabolic syndrome and its clinical determinants among primary care patients in different sociodemographic groups (study 2). In study 1, a systematic literature review was conducted on eight databases during Sept.-Oct. 2016 with a final update in Nov. 2017. In study 2, data (n=557 for RO II-III, n=251 for RO IV-V) collected in primary care practices in Central Finland in 2006-2008 for the EVI study were analysed using Chi-Square test, GLM and Logistic Reg…
