background : neospora caninum is considered one of the major causes of repeated abortions in livestock. this study aimed to determine the seropositivity to n. cani-num using indirect elisa and the influence of the infection on the occurrence of abortions in selected dairy herd in slovakia. method: blood samples were obtained from 490 cattle over a period of two years and were tested for n. cani...

A rapid, sensitive, specific and high through-put enzyme-linked immunosorbant assay (ELISA) methodfor determination of morphine in urine samples using penicillinase as label enzyme has been developed. Noextraction or chromatography was included in this assay procedure. Immunoglobulin (Ig) purified polyclonalanti-bodies against a C6-hemisuccinate derivative of morphine (M-C6-HS...

A sensitive ELISA was developed for the detection of amoxicillin (AMX) in serum, urine, and milk. The ELISA used an indirect competitive method produced by coating the plate with ovalbumin conjugated with AMX hapten. Antibodies against AMX-BSA were detected by a goat-antirabbit antibody conjugated with peroxidase. Calibration standard curves ranged from 1.28 ng/mL to 20 microg/mL [IC(50) (inhib...

background: canine parvovirus (cpv) infection is one ofthe most common causes of infectious gastroenteritis in dogs andis a highly contagious, often fatal disease. the original virus(cpv type 2) has had some mutations since its emergence andnew variants (cpv-2a, 2b and 2c) have been reported from manycountries all around the world. early diagnosis and treatment canprofoundly affect the disease ...

prangos ferulacea is a plant found in the mediterranean and middle-east regions used as carminative, anti-flatulent, emollient and antibacterial herb. it is believed that the coumarins are responsible for some of known effects of  prangos . in this research the relaxant effects of p. ferulacea coumrin rich extract as well as osthole as its main prenylated coumarins were investigated on rat ileu...

This paper describes the meta-level control system of a program (Dominic) for parametric design of mechanical components by iterative redesign. We view parametric design as search, and thus Dominic is a hill climbing algorithm. However, from experience with Dominic we concluded that modeling engineering design as hill climbing has several limitations. Therefore, a need for meta-level control kn...

Arboviruses have been shown to circulate in Madagascar, including West Nile, dengue, and chikungunya viruses, though the extent of their circulation remains poorly documented. We estimated seroprevalence these three arboviruses Madagascar determined risk factors associated with seropositivity. Serum samples obtained from 1680 individuals surrounding Sentinel Health Centers network all regions c...
