aflatoxin is one of the most hazardous mycotoxins injurious to both humans and animals. aflatoxin contamination of crops is a serious economic loss inflicted upon agriculture, food and animal industry throughout the entire world. in nature, there are microorganisms able to alleviate aflatoxin contamination in crop products. in this work, the effects of four strains of bacillus subtilis in reduc...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
Flavonoids from Marchantia convoluta (MCF) were studied for their ability to inhibit the proliferation of 2.2.15 cells. All concentration of MCF inhibited the secretion of HBsAg and HBeAg in the cultured medium by 2.2.15 cells. Analysis of morphological changes of MCF-treated cells by phase-contrast microscopy revealed a possible mode of action for MCF: inhibition of proliferation of 2.2.15 cel...
in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
Cryptolepine is the major alkaloidal constituent of the West African climbing shrub Cryptolepis sanguinolenta, a species used in traditional medicine for the treatment of malaria and a number of other infectious diseases. Cryptolepine and a number of its synthetic analogues have been shown to have potent antiplasmodial activities using P. falciparum lactate dehydrogenase assay (PfLDH). Intraery...

The mode of action of tomaymycin (TM) which is a new antibiotic with antitumor activity was studied. Inhibition of the incorporation of labeled precursors into the acid-insoluble fraction of Bacillus subtilis cells indicated that TM inhibits nucleic acids biosynthesis, while having relatively little effect on protein synthesis. TMdisplaced methyl green (MG) from a MG-DNA complex and a TM-DNA co...
