Cerebrovascular disease is one of the leading causes of death in the world, and about one-fourth of cerebrovascular deaths are due to ruptured cerebral aneurysms (CA). Hence it is important to find a way to reduce aneurysm formation and its subsequent morbidity and mortality. Proteolytic activity capable of lysing gelatin has been shown to be increased in aneurysm tissue and expressio...

objective: we studied both the presence of some carbohydrate compounds in a three-dimensional (3d) matrix harvested from human gingiva and the cell behavior in this matrix. materials and methods: in this experimental research, in order to prepare 3d scaffolds, human palatal gingival biopsies were harvested and physically decellularized by freeze-thawing and sodium dodecyl sulfate (sds). the sca...

Matrix metalloproteinases are an integral component of the organ-specific tissue microenvironment, primarily participating in regulation state integrative-buffer metabolic environment, remodeling, morphogenesis and immunogenesis, genesis pathological vascular diseases. Therefore, issues related to matrix metalloproteinase activity under altered gravity a matter high urgency for space biomedicin...

background the association between tumor necrosis factor-alpha (tnf-α) (-308 g/a) gene polymorphisms and level of tissue destruction and periodontal disease progression is not proved. objectives the present study investigated the stereological parameters of interdental papilla in chronic periodontitis (cp) patients with tnf-α (-308 g/a) gene polymorphisms. materials and methods sixty gingiva sa...
