objectives the current research aimed to study achillea millefolium and thymus vulgaris antiviral activity against newcastle disease virus (ndv). materials and methods the antiviral activity of the plants was measured by the reduction assay of viral titer, and explained by inhibition percentage (ip). background nowadays natural products such as pure compounds and plant extract scan provide unli...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
Hepatitis C virus (HCV) is one of the leading causes chronic liver disease. Hepatocellular carcinoma (HCC) a major complication associated with HCV infection, significant mortality and morbidity rates. This study aimed to measure biochemical parameters RNA levels for detection severity hepatitis virus- hepatocellular carcinoma. The was conducted on 100 patients, ages ranging from 36 68 years p...
nowadays, technical terminology translation plays an important role in human life. specific groups of people all over the world refer to learn these terminologies in order to be familiar with a subject and improve their knowledge in that domain. on the other hand, saving the technical translation equivalent is a particularly salient challenge for technical translators. the present study was con...
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
The aim of this experiment was to study the effect of in ovoinjection of royal jelly (RJ) on growth performance and immune response in broiler chickens challenged with Newcastle disease virus. A total of 200 hatching eggs were divided into four groups of 50 eggs each one using a completely randomized design. The eggs were injected with sterilized sodium bicarbonate buffer (pH=10.4) or RJ (88%) ...
abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
abstract background and aims: newcastle disease (nd) is a highly contagious disease that affects many species of birds and causes significant economic losses to the poultry industry worldwide and the pathogenicity of newcastle disease virus (ndv) strains varies with different virulence. we aim to detect lentogenic (low virulence) nd virus (nd/ir 2010) using sentinel birds and molecular detectio...
Newcastle disease (ND) is a paramyxovirus-based infectious, highly contagious, and pathogenic avian viral disease. Despite the widespread use of ND vaccinations, remains danger to poultry breeders worldwide. The specific goal this study was identify best vaccination route against in layer hens at production stage following oily vaccine. One hundred chickens 30 weeks age were collected from floc...
to compare the performance of fifteen hybrids of silkworm, bombyx mori l. under natural rearing conditions on the farm level and determine their resistance to grasserie disease, an experiment was conducted in a completely randomized design (15 treatments and five replications) for either of non-infected or infected to npv conditions. treatments included hybrids xinhang1?koming1, xinhang1?koming...
