Betanodavirus is one of the two genera making up the family Nodaviridae and is the etiological agent of viral nervous necrosis (VNN, also known as viral encephalopathy and retinopathy or VER). The virus infects a large range of host species in more than 50 species of marine and freshwater fish worldwide from different geographical areas and the known host range continues to expand as new specie...
In spite of the economic importance of powdery mildew on cucurbits, literature and databases about the fungal species reveal different species numbers and names, often indicating only two species, with inconsistent host specificities for different members of Cucurbitaceae. Revision of the available literature indicates the presence of at least six species of powdery mildews on Cucurbitaceae wit...
the outcome of this research is a practical framework for “idea generation phase of new product development process based on customer knowledge”. in continue, the mentioned framework implemented in a part of iran n.a.b market and result in segmenting and profiling this market. also, the critical new product attributes and bases of communication message and promotion campaigns extracted. we have...
The presence of the anisakid nematode Hysterothylacium gadi aduncum (Rudolphi, 1802) is reported for the first time in cultured rainbow trout (Oncorhynchus mykiss Walbaum, 1792) as a new host in freshwater farms from Turkey. This marine parasitic nematode is thought to complete the life cycle in fresh water and rainbow trout could act as the definitive host for this parasite under fresh water c...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
Leuciscus persidis as Iranian endemic fish in Kaftar lake and its headwaters (Mesopotamian subregion, Kor-Neiriz basin and Shadkam river) has been infected with a species of Dactylogyrus sphyrna. Comparison of collected parasites with Euro-Asian subregion showed that the similarity of them is more than their differences, although a little difference between them was observed. In this paper also...
In this study, 10 species of Bipolaris viz.B. bicolor, B. cynodontis, B. cylindrica, B. hawaiiensis,B. prieskaensis, B. sorghicola, B. sorokiniana,B. spicifera, B. zeae and B. zeicola and four species of Curvularia viz.C. fallax, C. heteropogonicola, C. inaequalis and C. lunata were identified on graminicolous species or soil. Bipolaris cylindrica, B. prieskaensis, B. zeae,C. fallax and C. hete...
in 1909, several years before the famous `organizer’ experiments of spemann and mangold, ethel browne demonstrated induction of a secondary axis in hydra by grafting a hypostome. based on this and subsequent work, in the late sixties, lewis wolpert proposed the theory of morphogen gradients and positional information. we have studied secondary axis induction by hypostome and foot tissue using t...
According to the World Health Organization, viable probiotics could have health effects. However, in recent years, many benefits have been observed through application of inactive and non-viable cells of microbes or their metabolites. Therefore, probiotics could be defined as viable, inactive, or non-viable microbial cells or cell extracts that have beneficial health effects on the host. Based...
