background: the most devastating manifestations of diabetes mellitus are vascular complications. although there are many factors involved in the pathogenesis of diabetic vasculopathy, many studies suggest a role for glucose–induced oxidative stress. studies in animal models, have demonstrated that the administration of antioxidants restores normal endothelial functions. the study was designed t...

osteoarthritis (oa) a common disease of aged population and one of the leading causes of disability. incidence of knee oa is rising by increasing average age of general population. age, weight, trauma to joint due to repetiting movements in particular squatting and kneeling are common risk factors of knee oa. several factors including cytokines, leptin, and mechanical forces are pathogenic fact...

mirs are 17-25 nucleotide non-coding rnas. these rnas target approximately 80% of protein coding mrnas. mirs control gene expression and altered expression of them affects the development of cancer. mirs can function as tumor suppressor via down-regulation of proto-oncogenes and may function as oncogenes by suppressing tumor suppressors. myeloproliferative neoplasias (formerly known as chronic ...

in the latest articles which were published during 2013-2014, trichomonas vaginalis ( t. vaginalis ) was mentioned as a neglected sexual transmission disease (std), while the exact mechanism of its pathogenesis has not been cleared yet. although trichomonasiasis is easy curable, there is concern that resistance to drug are increasing. this common infection as concerning the important public hea...

The clinically and pathophysiologically distinct entities of portopulmonary hypertension and hepatopulmonary syndrome occur in a substantial proportion of patients who have advanced liver disease of different causes. These disorders are notoriously underdiagnosed, but they have a substantial impact on survival and require focused treatment. Abnormal intrapulmonary vascular dilatation, the hallm...

Pulmonary arterial hypertension is a complex pulmonary vascular disease with a broad range of abnormal vascular abnormalities. Vasoconstriction, remodeling and thrombosis contribute to some extent to increased pulmonary vascular resistance and pressure. This review presents current knowledge on the role of the thrombotic process in the pathogenesis of PAH and evaluates the rationale for anticoa...

Reactive oxygen species have been implicated in the pathogenesis of virtually every stage of vascular lesion formation, hypertension, and other vascular diseases. We are currently gaining insight into important sources of reactive oxygen species in the vessel wall, including the NADPH oxidases, xanthine oxidase, uncoupled nitric oxide synthase, and mitochondrial sources. Although various reacti...

Calcific uremic arteriolopathy, otherwise known as calciphylaxis, is a rare disease characterized by skin ulceration and tissue necrosis, likely the result of vascular calcification with accompanying intimal hypertrophy and small vessel thrombosis. Although most often associated with end-stage renal disease, it has also been seen in a number of other disorders (collectively referred to as nonur...

Vascular diseases are usually caused by multifactorial pathogeneses involving genetic and environmental factors. Our current understanding of vascular disease is, however, based on the focused genotype/phenotype studies driven by the "one-gene/one-phenotype" hypothesis. Drugs with "pure target" at individual molecules involved in the pathophysiological pathways are the mainstream of current cli...
