    Magister-uppsats, Umeå universitet/Institutionen för psykologi

    Författare :Charlotte Jansson; [2022]
    Nyckelord :Depression; stress; anxiety; digitized cognitive screening; cognition; executive functions; attention; memory.; Depression; stress; ångest; digital kognitiv mätning; kognition; exekutiva funktioner; uppmärksamhet; minne.;

    Sammanfattning : Digital självadministrerande mätning av kognitiv förmåga gör det möjligt att snabbt och smidigt upptäcka kognitiv nedsättning associerad med psykisk ohälsa. Studien ämnade att undersöka samband mellan självskattning av depression, ångest och stress med prestation på Mindmores digitala självadministrerande testbatteri. LÄS MER

  3. 22. The effects of urine adulteration with oxidants before drug analysis with LC-HRMS and CEDIA

    Kandidat-uppsats, Uppsala universitet/Institutionen för medicinsk cellbiologi

    Författare :Anna Nilsson; [2022]
    Nyckelord :Drugs of abuse; Manipulation; Mass spectrometry; Narcotics; Tampering;

    Sammanfattning : In drug analysis, different kinds of immunoassays are often used as an initial screening for urine samples. The positive screening results are then followed by a confirmatory test, which consists of mass spectrometry methods to detect the drugs. The confirmatory tests are considered to be more resistant to manipulation than the screening tests. LÄS MER

  4. 23. Negative Screening : an analysis of the cost or benefit related to screening on industries

    Master-uppsats, Uppsala universitet/Företagsekonomiska institutionen

    Författare :Elin Kristoffersson; Noël Klarberg; [2022]
    Nyckelord :Sustainable finance; ESG; negative screening; industries; risk-adjusted return; cost; benefit; portfolio performance; CAPM; Fama-French; Carhart; Sharpe ratio;

    Sammanfattning : This thesis studies the increasingly prevalent concept of sustainability in a financial context. Specifically, the question as to whether negative screening implies a cost or a benefit from an investor perspective is derived from past research’s inconclusive findings. LÄS MER

  5. 24. Development of Microfluidic 3D Cell Culture with a Nanocellulose-Based Scaffold for Spheroid Formation as a Potential Tool for Drug Screening

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Sara Payande; [2022]
    Nyckelord :3D cell culture; Scaffold; Microfluidics; Layer-by-Layer; Cellulose Nanofibrils; Spheroids; HepG2; 3D cellodling; Matris; Mikrofluidik; Layer-by-Layer; Cellulosa Nanofibriller; Sfäroider; HepG2;

    Sammanfattning : Abstract  Lack of clinical relevance is assumed to be the main reason behind the high failure rate of medical drugs in the very initial phases of clinical trials. Clinical relevance is difficult to achieve with current tools as they lack the biological and physiological cues found in vivo. LÄS MER

  7. 25. Utvärdering av antibakteriell aktivitet hos växtextrakt utvunna från svenska örter

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Lotta Pihlo; [2022]
    Nyckelord :Antibiotic resistance; antibiotic; resistance determination; plant extracts; pathogenic bacteria; antimicrobial effect; Antibiotikaresistens; antibiotika; resistensbestämning; växtextrakt; patogena bakterier; antimikrobiell effekt;

    Sammanfattning : Infections caused by antibiotic resistant pathogenic bacteria is an increasing issue inhealthcare, and development of new antimicrobial substances could contribute to combat the continued spread. Plants have historically been used in traditional medicine, have intrinsic defense mechanisms against microbes, and could therefore be a source for new antimicrobial agents. LÄS MER
