Mixtures of the pesticides carbaryl and thiabendazole were studied using solid phase spectrophosphorimetry at room temperature with Whatman No. 4 filter-paper as solid support and Pb(ii) as enhancer of the phosphorescence. The transmitted phosphorescence was used as an analytical signal and its measurement was performed by placing the paper containing the sample between two quartz plates. In th...

Centromere binding factor 1 (Cbf1p or CP1) binds to the CDEI region of Saccharomyces cerevisiae centromeres and is a member of the basic helix-loop-helix (bHLH) class of proteins. Deletion of the gene encoding Cbf1p results in an increased frequency of chromosome loss, hypersensitivity to low levels of microtubule disrupting drugs (such as thiabendazole and benomyl) and methionine auxotrophy. B...

A conditioned taste aversion (CTA) is acquired through an association between the taste of a food and a feeling of illness experienced after ingestion. It can be induced deliberately by the addition of an undetectable illness-inducing chemical to food. Harnessing the CTA response could provide humane and effective means of controlling vertebrate pest problems. For field use, the ideal illness-i...

Tritrichomonas foetus is a venereal pathogen of cattle, which causes infertility, early embryonic death or abortion. In order to evaluate the potential trichomonicidal activity of benzimidazoles, the effects of thiabendazole, mebendazole and albendazole were analyzed on the multiplication, general morphology and ultrastructure of T. foetus. It was found that mebendazole presented the highest IC...

The effects of therapy with thiabendazole were investigated in 43 men who had been infected with Strongyloides stercoralis for 35 years. Side effects of drug treatment were frequent and sometimes severe; nausea was the most common symptom. Six months later, approximately one third of patients had persistent diarrhoea, recurrent urticaria or considered that their general health had not improved....

Objective. To evaluate in vitro antifungal activity of thiabendazole against strains of dermatophytes using a reference method for filamentous fungi. Materials and Methods. Dermatophytes' susceptibility to thiabendazole (TBZ) and fluconazole (FCZ) was evaluated using macrodilution method of protocol M38-A2 of the Clinical and Laboratory Standards Institute (CLSI). Results. MIC ranges of TBZ for...

Multicolor fluorescence in situ hybridization (FISH) was used to investigate the induction of aneuploidy during meiosis in young adult male mice treated with chemicals chosen for the EU sponsored aneuploidy project (acrylamide, colchicine, diazepam and thiabendazole). The aim of the present study was to evaluate the frequency of aneuploid sperm induced by each of these chemicals by sperm FISH. ...

Studies in diverse organisms have revealed a surprising depth to the evolutionary conservation of genetic modules. For example, a systematic analysis of such conserved modules has recently shown that genes in yeast that maintain cell walls have been repurposed in vertebrates to regulate vein and artery growth. We reasoned that by analyzing this particular module, we might identify small molecul...

In this study we have evaluated the application and reliability of using fluorescence (FLUO)-based high throughput screening assays with recombinant CYPs (rCYP). This was accomplished by screening 29 clinically important antiparasitic drugs for inhibition of the five major drug-metabolizing CYPs (-1A2, -2C9, -2C19, -2D6, and -3A4). Data from FLUO/rCYP assays were compared with that obtained by ...

infestation of soil and night-soil with the eggs or larvae of soil-transmitted helminthes is very important factor in the transmission of these infections. the effect of various temperatures and different chemicals on the development of larva inside the eggs of ascaris, which is the most resistant eggs or larvae of helminthes, or destruction of developed larvae inside the eggs has been evaluate...
