recently, some natural products have been used in the fields as alternative to synthetic compounds, to minimize the negative impacts to the environment. this study aimed to verify the effects of neem-based bio-pesticide in causing acute toxicity for a fish and chronic toxicity for a microcrustacean. to this end, danio rerio and daphnia magna were exposed to various concentrations of a neem-base...

background: pseudomonas spp. are of important food spoiling bacteria. they present around the world and are isolated from diverse sources. the main objective of this survey was to detect pseudomonas spp. in fresh chicken and fish obtained from markets of assiut city, egypt.  methods: in this cross-sectional survey, 50 samples of fresh raw chicken and 50 samples of fresh raw fish meat were rando...

introduction: angiogenesis, the process of new blood vessel formation from pre-existing vessels, has important physiological roles in embryonic development, female reproduction cycle, and wound healing. it is also crucial for pathological processes in several diseases especially tumor growth and metastasis. thereby, inhibition of angiogenesis as an addition to the conventional therapies such as...

a highly efficient cloning vector was constructed for cloning pcr products by inserting an 80 bp dna fragment into pgem-5zf (+) vector. the xcm i digestion of this vector gave rise to a 3’ overhanging deoxythymidine offering the possibility of cloning pcr products with 3' adenosine overhang created by taq dna polymerase. furthermore, two ecor i sites were added to the construct for identificati...

Given a labeling c of the edges of a directed graph E by elements of a discrete group G, one can form a skew-product graph E ×c G. We show, using the universal properties of the various constructions involved, that there is a coaction δ of G on C∗(E) such that C∗(E ×c G) is isomorphic to the crossed product C ∗(E) ×δ G. This isomorphism is equivariant for the dual action δ̂ and a natural action ...
