In this paper we introduce a minimalist hypothesis for keywords extraction: keywords can be extracted from text documents by considering concepts underlying document terms. Furthermore, central concepts are individuated as the concepts that are more related to title concepts. Namely, we propose five metrics, that are diverse in essence, to compute the centrality of concepts in the document body...

•Extending our previous work on visual keywords, we use the concept of template-based visual keywords using MPEG-7 color descriptors. MPEG-7, also called the Multimedia Content Description Interface, has been a standard for many years. These color descriptors have the ability to characterize perceptual color similarity and need relatively low complexity operations to extract them, besides being...

measurement of serum creatinine (cr) and blood urea nitrogen (bun) are used as indicators of glomerular filtration rate. the increased levels of these biomarkers are usually detectable at advanced stages of kidney complications. the aim of this study was to find the interrelationship of beta-2 microglobulin (β2m), bun and cr in streptozotocin (stz)-induced diabetes mellitus in rabbits. diabetes...

objective: barberry root extract contains various alkaloids that are considered as antioxidants. beneficial effect of aqueous extract of berberis integerrima root (aebir) was evaluated for renal function in diabetic rats induced by stz. material and methods: diabetes was induced by i.p. injection of streptozotocin (65 mg/kg bw) to rats, after 15 h of fasting. diabetic rats were randomly grouped...

objective: frankincense improves memory in different models of learning. however, its influence on models of alzheimer's disease (ad) has not been studied widely. in the present study, the therapeutic effect of frankincense was evaluated in a model of ad induced by i.c.v administration of streptozotocin. materials and methods: under stereotaxic surgery, two guide cannulas were implanted in...

objectives: a wide range of liver and kidney disorders are associated with diabetes and there is a mutual relationship between diabetes and these diseases. herbal medicine with having abundant ingredients is one of these options. the goal of this study was to compare the effects of alcoholic extract of aerial parts of salvia hydrangea with glibenclamide on functional tests of liver and kidney i...

objective(s):the present study investigated the antidiabetic and hypolipidemic properties of dorema aucheri leave hydroalcoholic extract in nicotinamide-streptozotocin induced type 2 diabetic rats. materials and methods: nicotinamide/streptozotocin-induced diabetic rats were supplemented orally with three different doses of d.  aucheri (100, 200 and 400 mg/kg bw) or glibenclamide (0.25 mg/kg) f...

The effects on the pancreatic B cell of streptozotocin and its aglucone derivative N-nitrosomethylurea were investigated in obese-hyperglycaemic mice and their lean littermates. Both streptozotocin and N-nitrosomethylurea were found to be B-cytotoxic although N-nitrosomethylurea produced less islet damage. Both substances decreased the concentrations of NAD(+) in the islet cells to about 10% of...
