  1. 1. Genetic and epidemiological aspects of implantation defects Studies on recurrent miscarriage, preeclampsia and oocyte donation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Evangelia Elenis; Agneta Skoog Svanberg; Alkistis Skalkidou; Gunilla Sydsjö; Helena Åkerud; Anja Pinborg; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; genetic polymorphism; gestational hypertensive disorders; Histidine-rich glycoprotein; HRG; implantation defect; oocyte donation; placentation; preeclampsia; recurrent miscarriage; SNP.; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Abstract : Implantation requires complex molecular and cellular events involving coagulation, angiogenesis and immunological processes that need to be well regulated for a pregnancy to establish and progress normally.  The overall aim of this thesis was to study different models associated with atypical angiogenesis, impaired implantation and/or placentation, such as recurrent miscarriage (RM), oocyte donation (OD) and preeclampsia.

  2. 2. Bone Healing after implantation of bone substitute materials. Experimental studies in estrogen deficiency

    University dissertation from Umeå universitet

    Author : Sven Öberg; Jan Rosenquist; Ulf Lekholm; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Bone grafts; hydroxyapatite; estrogen deficiency; demineralised bone; bone formation; AAA bone; bone defect; titanium implants; resonance frequency analysis.; Kirurgi; MEDICINE Surgery; MEDICIN Kirurgi; kirurgi; Surgery;

    Abstract : Bone formation and bone healing were studied in the mandible, tibia and skull bones in adult, healthy and estrogen deficient rabbits implanted with different bone substitutes.In the first study an evaluation of the differences in bone regeneration in and around solid (Alveograf *) and porous hydroxyapatite (Interpore 200*) was undertaken.

  3. 3. Luminescence of Silicon Nanoparticles Synthesized by Ion Implantation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Thawatchart Chulapakorn; Anders Hallén; Daniel Primetzhofer; Yanwen Zhang; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silicon nanoparticle; Photoluminescence; Ion beam synthesis; Ion beam analysis; Fysik; Physics;

    Abstract : Silicon nanoparticles (SiNPs) have been shown to display luminescence in the visible range with a peak wavelength depending on the nanoparticle size. This finding is of potential interest for integration of optoelectronic devices in semiconductor technology. READ MORE

  4. 4. Chondrocytes Differentiation- Biological and Biomaterial Perspectives

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hanna Stenhamre; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; scaffold.; chondrocyte implantation; cartilage tissue engineering; dedifferentiation; redifferentiation;

    Abstract : Articular cartilage is an avascular tissue and once injured it does not heal spontaneously. A successful tissue engineering approach for cartilage reconstruction is autolougus chondrocyte implantation (ACI). READ MORE

  5. 5. Zinc Oxide Bulk and Nanorods

    University dissertation from Göteborg : University of Gothenburg

    Author : Peter Klason; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zinc oxide; Schottky contact; buckling; annealing; semiconductor growth; ion implantation; photoluminescence; nanorods;

    Abstract : Zinc Oxide (ZnO) has many promising properties for optoelectronics, sensor applications, transparent electronics etc. To mention a few, ZnO has a large exciton binding energy (60 meV at room temperature) and a direct wide bandgap energy of 3.37 eV. In addition, ZnO is piezoelectric and shows more resistance to radiation damage than Si and GaN. READ MORE
