  2. 1. Redox effects on neutrophils in wound healing conducted by wound dressings and hyperbaric oxygen

    Author : Herman Sahlin; Göteborgs universitet; []
    Keywords : neutrophil granulocyte; wound healing; wound dressing; reactive oxygen species; NO; hyperbaric oxygen; bacterial killing;

    Abstract : The increased influx of neutrophils into chronic wounds results in increased production of reactive oxygen species (ROS), nitric oxide (NO) and lipid peroxidation products (LPP), as well as a ROS-induced increase in protease levels. The NO and LPP impair the respiratory burst response of the neutrophils and reduce their capacity to kill bacteria and digest debris. READ MORE

  4. 2. Studies of chronic ulcers and larval therapy

    Author : Helene Wolff; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic ulcers; wounds; larval therapy maggot; MRSA; debriding; proteases; larval therapy; maggot; debriding. proteases;

    Abstract : Our aims in this study were to learn more about chronic ulcer pathogenesis (Paper I) and larval therapy (Paper II-V).Materials and methods: Paper I: 26 bacterial isolates of P. aeruginosa from chronic ulcers were examined by PCR technique for detection of the genes of two virulence factors (elastase and alkaline proteinase).

  5. 3. Plasminogen : a novel inflammatory regulator that promotes wound healing

    Author : Yue Shen; Tor Ny; Gunilla Høyer-Hansen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Plasminogen; inflammation; wound healing; diabetic wounds; tympanic membrane perforations; medicinsk biokemi; Medical Biochemistry;

    Abstract : The plasminogen activator (PA) system has been shown to be intimately involved in wound healing. However, the role of this system in the initiation and resolution of inflammation during healing process remained to be determined. READ MORE

  6. 4. Bioactive nanocellulose materials for the treatment of chronic wounds

    Author : Anna Blasi Romero; Natalia Ferraz; Daniel Aili; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanofibrils; covalent immobilization; wound healing; antioxidant properties; antibacterial properties; anti-inflammatory properties; stimuli responsive hydrogels; reactive oxygen species; host defense peptides; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Abstract : Chronic wounds represent a burden for the healthcare system and significantly affect the quality of life of the patients. There is currently a lack of efficient treatments but new, improved therapeutic approaches are under development. READ MORE

  7. 5. Corneal cellular proliferation and wound healing

    Author : Lisha Gan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : cornea; cell proliferation; wound healing; stem-cells; leukocytes; PCNA; hyaluronan; alkali injury; photorefractive keratectomy;

    Abstract : Background: Cellular proliferation plays an important role in both physiological and pathological processes. Epithelial hyperplasia in the epithelium, excessive scar formation in retrocorneal membrane formation and neovascularization are examples of excessive proliferation of cornea cells. Lack of proliferative ability causes corneal degeneration. READ MORE
