  1. 1. Symptom persistence of ADHD and quality assessment of measurements : A scoping review

    Uppsats för yrkesexamina på avancerad nivå, Linnéuniversitetet/Institutionen för psykologi (PSY)

    Författare :Elin Jonsson; Matilda Holmgren; [2023]
    Nyckelord :ADHD; Symptom persistence; Review; Open Science; Risk of bias; ADHD; Symtomstabilitet; Översikt; Open Science; Risk för bias;

    Sammanfattning : Background: Despite the high prevalence of ADHD, results of research on persistence rates remain scattered. Previous studies identify methodological limitations resulting in various developmental trajectories of ADHD symptoms. LÄS MER

  3. 2. Safety and Stability of Samples Stored on Filter Paper for Molecular Arbovirus Diagnosis

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Emelie Bringeland; [2021]
    Nyckelord :Arthropod-borne viruses arboviruses ; alphaviruses; flaviviruses; dengue virus DENV ; Japanese encephalitis virus JEV ; Tick-borne encephalitis virus TBEV ; Usutu virus USUV ; Zika virus ZIKV ; Flinders Technology Associates™ card FTA ; Biosafety; Vietnam;

    Sammanfattning : Expanding urbanization, climate change, and population growth contribute to increased transmission and spread of arthropod-borne viruses (arboviruses), many of which cause severe disease in humans. Pathogenic arboviruses include dengue, Zika, tick-borne encephalitis, and sindbis viruses, which together threaten more than half the global population. LÄS MER

  4. 3. Implementation of a straightforward derivatizationmethod for the simultaneous analysis of short chainfatty acids and tricarboxylic acid cycle metabolitesby LC-qToF-MS.

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Renée Levisson; [2021]
    Nyckelord :Short-chain fatty acids; tricarboxylic acid TCA cycle; chemical derivatization; 3-nitrophenylhydrazine;

    Sammanfattning : Short-chain fatty acids (SCFAs) and the tricarboxylic acid (TCA) cycle metabolites aresmall hydrophilic compounds that play crucial roles in biological species ranging fromenergy metabolism, immune homeostasis to cellular signalling. There is a need for reliableand precise quantification of these metabolites in biological matrices as they can providecrucial information of metabolic status and potentially be used as diagnostic biomarkersfor different pathological and physiological conditions.

  5. 4. Pulsed Laser Beam Quality Assessment via Phase Retrieval

    Master-uppsats, Lunds universitet/Atomfysik

    Författare :Mattias Ammitzböll; [2021]
    Nyckelord :GSA; phase retrieval; Gerchberg-Saxton; femtosecond; pulsed; laser; beam quality; attosecond; interferometry; Physics and Astronomy;

    Sammanfattning : In the search for a better understanding of the fundamental nature of the atom, the development of femtosecond pulsed laser sources has opened up for many applications, in particular in time-resolved physics. For many of those, like the generation of attosecond pulses through high-order harmonic generation, high intensity is needed and the quality of the beam is a critical factor. LÄS MER

  7. 5. Verification of hypochromic erythrocytes on Sysmex XN 2000

    L3-uppsats, Uppsala universitet/Institutionen för kvinnors och barns hälsa

    Författare :Dakakni Aghyad; [2020]
    Nyckelord :Anemia diagnosis and management; Calculation of Erythrocyte Parameters; Functional iron deficiency; Hemoglobin; Hematology analyzer.;

    Sammanfattning : Anemia is a serious blood disease that more than two billion suffer from worldwide. Half of that number consist of iron deficiency anemia, which is insufficiency of iron supply to the bone marrow due to empty iron store or hampered iron utilization due to inflammation. Therefore, requires rapid diagnosis. LÄS MER
