a total of 332 birds including 149 sparrows, 147 doves and 36 pigeons were examined for toxoplasma infection by both direct agglutination for detecting antibodies to toxoplasma and direct parasitological test to detect the cyst of toxoplasma in the brain of birds. the toxoplasma sero-positive rate (spr) in the examined birds was 10.5 percent (27 cases) with titers of 1:40 or higher and spr in e...

This work develops a highly sensitive immunoassay sensor for use in graphene oxide sheet (GOS)-based surface plasmon resonance (SPR) chips. This sensing film, which is formed by chemically modifying a GOS surface, has covalent bonds that strongly interact with the bovine serum albumin (BSA), explaining why it has a higher sensitivity. This GOS film-based SPR chip has a BSA concentration detecti...

Surface plasmon resonance (SPR) is a label-free, highly-sensitive, and real-time sensing technique. Conventional SPR sensors, which involve a planar thin gold film, have been widely exploited in biosensing; various miniaturized formats have been devised for portability purposes. Another type of SPR sensor which utilizes localized SPR (LSPR), is based on metal nanostructures with surface plasmon...

The surfactant precipitation and recovery method (SPR method) consist of a step, that is protein-surfactant complex by the addition aqueous solution to protein solution, dissolution precipitate in polar organic solvent trace amount salt solution. When denaturant was not included, ratio lysozyme increased as AOT/lysozyme molar increased, after reaching 100%, decreased due redissolution precipita...

background: the superiority of either of body mass index (bmi), waist circumference (wc), waist-to-hip ratio (whr) and waist-to-height ratio (whtr) for prediction of metabolic syndrome (mets) is remained controversial in asian population. the objective of this study was to compare the discriminative capacity of either of these measures in prediction of non-adipose components of mets. methods: i...

The aim of this study is experimental assay of sensitivity and stability of a bimetallic silver/gold SPR sensor chip. This chip utilizes the sensitivity of the silver and the stability of the gold. Moreover, the Silver layer (instead of usual Cr or Ti layer) was used as an adhesive intermediate layer between the Gold layer and the glass substrate. The optimization of the Gold/Silver thickness u...

The Silver SPR chip was modified by alkaline-silane condensation with aminopropyltriethoxysilane (APTES) in NaOH aqueous solution at different times. Silver sputtered slides coated with APTES were immersed in NaOH solution, enabling us to produce silver surfaces homogeneously covered with APTES. The surface properties of grafted APTES on sputtered silver surface as a occasion of time were studi...
