2. 1. Ultrasonic Fluid and Cell Manipulation

   Author : Mathias Ohlin; Martin Viklund; Hans Hertz; Peter Glynne-Jones; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3D cell culture; Acoustic streaming; Acoustofluidics; Cell manipulation; High-resolution imaging; Multi-well; Microplate; Natural killer cell; Piezo; Radiation force; Solid tumor; Solubilization; Spheroid; Standing wave; Temperature control; Transducer; Trapping; Ultrasonic; Fysik; Physics; Biological Physics; Biologisk fysik;

   Abstract : During the last decade, ultrasonic manipulation has matured into an important tool with a wide range of applications, from fundamental cell biological research to clinical and industrial implementations. The contactless nature of ultrasound makes it possible to manipulate living cells in a gentle way, e.g. READ MORE

4. 2. Bioengineering and Cell-derived Strategies for Salivary Gland Regeneration

   Author : Jiao DONG; Lungbioengineering och regeneration; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular vesicles; precision-cut tissue slices; histology scoring; sustainable histology; salivary gland; human dental pulp stem cells; extracellulära vesiklar; stamceller från mänsklig tandmassa; precisionsskurna vävnadsskivor; Spottkörtel; hållbar histologi och histologipoäng;

   Abstract : Xerostomia (dry mouth symptoms) is a group of incurable debilitating conditions of salivary glands caused by aging, radiation/chemical exposure, or aberrant inflammation in the salivary glands. During this PhD thesis, we aimed to evaluate whether cell-derived strategies (e.g. READ MORE

5. 3. Ultraviolet Radiation and Squamous Cell Carcinoma in Human Skin

   Author : Cecilia Wassberg; Olle Larkö; Uppsala universitet; []
   Keywords : Medical sciences; Ultraviolet radiation; squamos cell carcinoma; incidence; sunscreens; p53; DNA damage; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Dermatology and Venerology; dermatologi och venereologi;

   Abstract : Ultraviolet radiation (UVR) is a major risk factor for development of skin cancer. UVR-induced DNA damage and a dysfunctional p53 protein are important steps in the development of squamous cell carcinoman in human skin (SCC). READ MORE

6. 4. Ultrasound-assisted Interactions of Natural Killer Cells with Cancer Cells and Solid Tumors

   Author : Athanasia Christakou; Martin Wiklund; Sabeth Verpoorte; KTH; []
   Keywords : Natural killer cell; cytotoxicity; heterogeneity; multiwell microchip; biocompatibility; ultrasonic cell manipulation; 3D cell culture; solid tumor; spheroid; high-resolution imaging; Biologisk fysik; Biological Physics;

   Abstract : In this Thesis, we have developed a microtechnology-based method for culturing and visualizing high numbers of individual cells and cell-cell interactions over extended periods of time. The foundation of the device is a silicon-glass multiwell microplate (also referred as microchip) directly compatible with fluorescence microscopy. READ MORE

7. 5. Single-Proton Irradiation of Living Cells - Development of New Tools for Low-Dose Radiation Research

   Author : Natalia Arteaga; Kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; lithography; UVL; EBL; SeACell; human hepatoma cells HepG2 ; reactive oxygen species ROS ; bystander effect; SU-8; cell recognition; cell irradiation; Single-Ion Hit Facility; low-dose; Fysicumarkivet A:2010:Arteaga Marrero;

   Abstract : A Single-Ion Hit Facility (SIHF) consists of a custom-build facility based in particle accelerators which offers irradiation controlling the number of delivered particles with a precise targeting localization. The irradiation spot can be confined down to the nanometre scale allowing the irradiation of subcellular compartments with a single particle. READ MORE
