The effects of L-tryptophan, L-kynurenine, 3-hydroxy-L-kynurenine, ascorbate, some amino acids, 5-hydroxy-L-tryptophan, anthranilate, sodium bisulfite, EDTA, divalent ions and ionic strength on purified liver arylformamidases of rainbow trout and cattle were investigated.
Implementing an e-business model for a dot-com SME: Lessons Learned" ABSTRACT One of the key steps to develop an e-business solution is the definition of a Business Model (BM), which requires the expertise from different areas such as finance, technology, marketing, and project management. It is known that Small and Medium Enterprises (SMEs) count with… (More)
1. Arylformamidases were purified from the liver of rainbow trout and cattle. 2. Optimal pH's were 7.7 and 8.0 for the fish and cattle enzyme, respectively. Both enzymes showed optimum temperature at 40 degrees C. Thermal and pH stability ranges and Arrhenius plots of the enzymes differed. 3. Km and molecular weight of the fish enzyme were determined to be… (More)
Flow cytometry is a potentially efficient approach for the quantification of parasitemias in experimental malaria infections and drug susceptibility assays using rodent malaria models such as Plasmodium berghei. In this study, we used two red DNA-binding fluorochromes, rhodamine 800 (R800) and LD700, to measure parasitemia levels in whole blood samples from… (More)
The existing works point out that smaller organisations have been shown to have different technology adoption patterns than large ones. However, it is unclear whether Small to Medium Sized Enterprises (SMEs) and large organisations take decisions for the adoption of integration technologies by focusing on different factors. Moreover, the literature also… (More)
1. In rainbow trout, 3HAA activity was comparable with those of terrestrial animals; 3HAA:PC activity ratio suggests ineffective conversion of tryptophan to niacin. 2. Inactivation as well as reactivation under different conditions was investigated. 3. Some characteristics of the enzyme extract were studied with the aim of optimizing assay in fish.
