  2. 1. Vascular remodelling and circulating basement membrane fragments in abdominal aortic aneurysm

    Author : Mari Holsti; Malin Sund; Anders Wanhainen; Joakim Nordanstig; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AAA; extracellular matrix; vascular remodelling; collagen; inflammation; Surgery; kirurgi;

    Abstract : An abdominal aortic aneurysm (AAA) is a degenerative disease, characterized by advanced inflammation and extracellular matrix (ECM) remodelling. Enhanced protease activity mediated by cytokines results in the degradation of ECM proteins, leading to the generation of different bioactive fragments. READ MORE

  4. 2. Topical anesthesia of the tympanic membrane : an experimental animal study

    Author : Sten-Hermann Schmidt; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Topical anesthesia; middle ear; tympanic membrane; cochlea; collagen fibres; lidocaine; 96 % phenol; Bonain s liquid; auditory brainstem response; ototoxicity; cytocochleogram; scanning electron microscopy; rat; guinea pig;

    Abstract : Myringotomy plays an important role in otological therapy. The procedure requires an efficient anesthesia, which can be obtained without general anesthesia. However, the use of local anesthetics on the tympanic membrane (TM) has been abandoned in many places, as general anesthesia has been readily available. READ MORE

  5. 3. Dentin surface conditioning : the role of collagen in dentin bonding

    Author : Andreas Cederlund; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Preparation of dental cavities inevitably produces a thin layer of smear, which covers dentin and enamel surfaces. This smear layer, which is between 1 and 10 gm thick, consists of hydroxyapatite, denatured collagen and remnants of cariogenic bacteria. If left untouched, it will weaken the bond between filling material and cavity wall. READ MORE

  6. 4. The Entheses of the Medial Meniscns and Ligaments of the Knee Joint : Descriptive and Experimental Studies

    Author : Jizong Gao; Michael Benjamin; Linköpings universitet; []
    Keywords : knee joint; meniscus; ligaments; insertion; enthesis; quantitative morphology; fibrocartilage; cement line; collagens; proteoglycans; nerve fibres; tensile strength; failure mode; transection; refixation; repair; healing; osteoarthrosis; histology; immunohistochemistry; biomechanics; rabbit model; MEDICINE; MEDICIN;

    Abstract : Meniscal injuries are common in sports. Surgical removal of the meniscus to relieve symptoms is associated with a high risk for late knee joint osteoarthrosis and pain. Meniscal repair or replacement has therefore been advocated. READ MORE

  7. 5. Cartilage Oligomeric Matrix Protein (COMP). Functions in collagen binding and assembly

    Author : Krisztina Rosenberg; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical biology; Klinisk biologi;

    Abstract : Connective tissues contain a prominent extracellular matrix that provides mechanical and physical properties. This extracellular matrix contains as a major constituent a network of collagen fibres. These are composed of collagen fibrils, which in turn are assembled from many collagen molecules aligned parallel to each other. Several proteins, e. READ MORE
