  1. 1. Fluorescent quantum dots and graphene-based sensors for forensic applications

    Författare :Johnny Jussi; Ying Fu; Simon Dunne; Qin Wang; Ingemar Petermann; Xin Wang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Quantum Dots; Blood; Forensics; Drugs; Biologisk fysik; Biological Physics;

    Sammanfattning : A key emerging concept within the forensic sciences today areportable measurementdevices, where a much more efficient usage of the resources involved with crime-solving is possible if confirmatory measurements can be realised directly at a crimescene with such devices. Today, the majority of the presently used methods duringcriminal investigation at a crime scene involves measurements of a presumptivenature, which is a vital tool as it enables the screening of samples.

  3. 2. Helicobacter pylori infection in a mouse model: Development, optimization and inhibitory effects of antioxidants

    Författare :Xin Wang; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; virology; bacteriology; Microbiology; mice; Helicobacter pylori; gastritis; lymphoma; antioxidant; diet; Th1 and Th2; cytokines; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Helicobacter pylori is a human pathogen strongly associated with chronic type B gastritis, peptic ulcer disease, gastric cancer and MALT lymphoma. Our aims were to establish a mouse model of H. pylori infection, to study pathogenesis of gastritis and gastric cancer and to investigate new treatment strategies in this model. LÄS MER

  4. 3. Structure and Properties of Perovskite SrTiO3 and Na0.5K0.5NbO3 Thin Films Fabricated by rf Magnetron Sputtering

    Författare :Xin Wang; Eric Cross; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Functional oxide thin films are getting more and more attention due to their unique dielectric, piezoelectric, ferroelectric, magnetic, superconducting properties. This thesis focuses on the growth, compositional control, and structure-property relationships of SrTiO3 and Na0.5K0.5NbO3 thin films. LÄS MER

  5. 4. Studies of overcoming acquired resistance : molecular mechanisms and development of novel drugs

    Författare :Xin Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Chemotherapeutic agents have become widely applied for treatment of various types of malignancies. Drug resistance unfortunately remains as a major obstacle for the effectiveness of chemotherapy. Cancer drug resistance includes two broad categories: intrinsic and acquired. LÄS MER

  7. 5. The impact of lifestyles on the occurrence of dementia

    Författare :Hui-Xin Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Alzheimer s disease; dementia; elderly; emotional support; folate; incidence; integration; intellectual activity; lifestyle; mental activity; physical activity; prevalence; productive activity; smoking; social activity; social network; risk factor; and vitamin B12.;

    Sammanfattning : This thesis explored the impact of different lifestyles in late life on the occurrence of Alzheimer's disease (AD) or dementia. Smoking, vitamin B12 and folate in relation to AD have been extensively studied, but the results are inconsistent. Research concerning the association between dementia and social network or social activities is scarce. LÄS MER
