  2. 1. Aiway Mucins: experimental models for studies of secretions

    Author : Naila Svitacheva; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cystic fibrosis; bovine trachea; radiolabelling; cell line; primary cell culture; organ culture; mucus; mucin; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Abstract : Mucins are essential components of the mucosal barrier. The complexity of the airway mucosal barrier is reflected in the lack of specific treatments to block mucin hypersecretion associated with several respiratory diseases such as chronic bronchitis, asthma and cystic fibrosis.

  4. 2. Cholesterol in T cells : homeostasis, plasma membrane organization and signaling

    Author : Saleemulla Mahammad; Ingela Parmryd; Thomas Harder; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Plasma membrane; T cells; Cholesterol; Lipid rafts; Membrane organization; Cholesterol homeostasis; cholesteryl esters; Cell biology; Cellbiologi; Cell Biology; cellbiologi; Cellbiology;

    Abstract : The plasma membrane of eukaryotic cells contains cholesterol and glycosphingolipids enriched nanodomains known as lipid rafts; which are believed to exist in a liquid ordered (lo) state. Methyl-beta-cyclodextrin (MBCD) is used to deplete cellular cholesterol and a widespread assumption is that MBCD preferentially targets cholesterol in lipid rafts. READ MORE

    Author : Mathias Ohlin; Martin Viklund; Hans Hertz; Peter Glynne-Jones; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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

  6. 4. Influences of in vivo and in vitro loading on the proteoglycan synthesis of articular cartilage chondrocytes

    Author : Mikko Lammi; Markku Tammi; Jukka Finne; Tim Hardingham; Finland Kuopio University of Kuopio Department of Anatomy; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; Articular cartilage; proteoglycans; loading; stress; hydrostatic pressure; biokemi; Biochemistry; cell research; cellforskning; molekylärbiologi; Molecular Biology; ortopedi; Orthopaedics;

    Abstract : In this study, the biosynthesis of proteoglycans (PGs) was examined in articular cartilage of canine hip joint after long-distance running experiment and in bovine chondrocyte cultures during in vitro loading with hydrostatic pressure. In addition, new assays were developed for more sensitive quantitation of glycosaminoglycans (GAGs) and PGs. READ MORE

  7. 5. Live Single Cell Imaging and Analysis Using Microfluidic Devices

    Author : Mohammad Ali Khorshidi; Helene Andersson-Svahn; Håkan Jönsson; Carolina Wählby; Johan Elf; KTH; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single cell analysis; time-lapse fluorescence imaging; automated image analysis; microwell; droplet microfluidics; NK cells; single cell tracking; migration behavior analysis; cell-cell interaction; optical microscopy; image analysis; image processing; microfluidics; immune cells; tracking; counting; morphology analysis;

    Abstract : Today many cell biological techniques study large cell populations where an average estimate of individual cells’ behavior is observed. On the other hand, single cell analysis is required for studying functional heterogeneities between cells within populations. READ MORE
