21. Plasminogen in periodontitis and wound repair
Sammanfattning : The plasminogen activator (PA) system plays a critical role in many physiological and pathological processes, such as fibrinolysis, extracellular matrix (ECM) degradation, wound healing, inflammation, and cancer. The key component of the PA system is plasmin, a broad-spectrum serine protease that is derived from its inactive form, plasminogen. LÄS MER
22. Nitric oxide in experimental pulmonary embolism
Sammanfattning : Nitric oxide (NO) is an important modulator of the pulmonary circulation both at basal state and in pulmonary hypertension. Low levels of NO are detectable in exhaled gas which is believed to mirror pulmonary NO formation and elimination. LÄS MER
23. Studies on a novel oxidative mechanism for elimination of extrahepatic cellular cholesterol
Sammanfattning : Recently, a new oxidative mechanism for elimination of cholesterol from extrahepatic cells by sterol 27-hydroxylase was described. This mechanism involves conversion of cholesterol into 27-hydroxycholesterol and cholestenoic acid. LÄS MER
24. Ridge alterations following tooth extraction and implant placement
Sammanfattning : The purpose of the present series of investigations was to study the healing following tooth extraction and implant placement. In an animal model, the healing sequence of tooth extraction sites (Study I), the influence of the periodontal ligament (PDL) on the healing of extraction sockets and the effect of various biomaterial on the healing of bone defects (Study II), and the healing of different bone block grafts placed on the surface of a narrow ridge (Study III) were investigated.
