Introduction: Acinetobacter baumannii is associated with hospital-acquired infections. Outer membrane protein A of A.baumannii (AbOmpA) is a well-characterized virulence factor which has important roles in pathogenesis of this bacterium. Methods: Based on our PCR-sequencing of ompA gene in the clinical isolates, AbOmpA protein can be categorized into two types, named here type-1 and type-2. We ...

The intracellular metabolic fluxes can be calculated by metabolic flux analysis, which uses a stoichiometric model for the intracellular reactions along with mass balances around the intracellular metabolites. In this study, we have constructed in silico metabolic pathway network of Escherichia coli consisting of 301 reactions and 294 metabolites. Metabolic flux analyses were carried out to est...

In this study, an in silico genome-scale metabolic model of steroidogenesis was used to investigate the effects of hypoxic stress on steroid hormone productions in fish. Adult female fathead minnows (Pimephales promelas) were exposed to hypoxia for 7 days with fish sub-sampled on days 1, 3 and 7 of exposure. At each time point, selected steroid enzyme gene expressions and steroid hormone produc...

objective(s): tyrosinase is a key enzyme in pigment synthesis. overproduction of melanin in parts of the skin results in hyperpigmentation diseases. this enzyme is also responsible for the enzymatic browning in fruits and vegetables. thus, its inhibitors are of great importance in the medical, cosmetic and agricultural fields. materials and methods: a series of twelve kojic acid derivatives wer...

BACKGROUND Nearly 15% of BRCA1 and BRCA2 DNA tests lead to the identification of Variants of Uncertain Significance (VUS). VUS are classified in the Netherlands according to the Bell system and it is current practice that class III VUS are communicated to counsellees, but not class II or lower VUS. Our aims were to investigate the utility of in silico characteristics in the classification of VU...

materials and methods in silico analysis of the cadf gene was carried out by several software and available online tools. a duplex pcr optimized with specific primers was used for detection and differentiation of both species. to evaluate specificity and sensitivity of the test, a panel of different campylobacter spp. together with several intestinal bacterial pathogens was tested. the limit of...
