purpose: the aim of the present study was to detect the expression of p-glycoprotein (p-gp) and multi-drug resistance associated protein 1 (mrp1) in retinoblastoma tumors, and analyze the relationship between its expression, the clinico-pathological features and recurrence. methods: p-gp and mrp1 expression in formalin-fixed paraffin-embedded retinoblastoma bearing ocular tissue sections from 2...

objective(s):some pathologic situations such as diabetes and metabolic syndrome are associated with alternation in nitric oxide level. incidence of these condition increases with aging. on the other hand, insulin secretion is modulated by nitric oxide, and nitric oxide synthase (nos) activity is also altered in diabetes. in this study, modification in the enzyme activity associated with aging a...

metabolic syndrome (mets) as a collection of obesity-associated disorders is associated with inflammation, oxidative stress, pro-thrombotic state, elevated risk of developing cardiovascular disease and type 2 diabetes. adiponectin is one of the most abundant peptide hormones derived from adipose tissue. this protein plays a major role in glucose and lipid metabolism and prevents development of ...

A specific and highly sensitive radioimmunoassay for determination of pregnancy-associated plasma protein A in human serum is described. The minimum detection limit for this protein was 2.9 micrograms/L. The within- and between-assay coefficients of variation were 4.0 and 4.5%, respectively. The circulating protein was detected within 32 days of conception in eight normal pregnancies and within...
