background & aim: aphids are of serious pests and vectors of multitude of viral diseases of field crops, vegetables, ‎and greenhouse crops. they have displayed a remarkable ability to establish resistance to ‎almost every insecticide with which it has been treated. to reduce the damage of these pests ‎and dependence on the sometimes unwise use of synthetic pesticides in crop and vegetable ‎...

Experiments were designed in a bioassay system to analyze the effect of elevated (from 5.9 mM to 7.5-45.9 mM) extracellular K+ concentration on the release of endothelium-derived relaxing factor. Segments of canine femoral artery with endothelium (donor segment) were mounted in an organ bath and perfused with modified Krebs-Ringer bicarbonate solution; the effluent from the donor segment was us...

An agar well diffusion bioassay method for determination of clarithromycin in human plasma, using Micrococcus Luteus ATCC 9341 as the assay organism, was compared with a selective high-performance liquid chromatographic (HPLC) method with UV detection. Spiked plasma was used to prepare standard and control samples for both methods. The results of the bioassay analyses with spiked plasma samples...

The standard procedure for definitive detection of BoNT-producing Clostridia is a culture method combined with neurotoxin detection using a standard mouse bioassay (MBA). The mouse bioassay is highly sensitive and specific, but it is expensive and time-consuming, and there are ethical concerns due to use of laboratory animals. Cell-based assays provide an alternative to the MBA in screening for...

conclusions the results of this study show that the beneficial effect of lactobacillus casei is related to its metabolites. a formulated gel shows a significant antidermatophytosis activity compared to clotrimazole. results the results showed the same effect of the probiotic extract against 4 pathogens; however, the greatest average zone of inhibition was measured 34 mm against t. rubrum. the m...

introduction pharmacologic treatment of radicular pain with oral medications is limited by adverse effects and concern for dependence. while topical formulations have been explored in pain research, there is no published literature evaluating the efficacy in radicular pain. we present the first three cases of radicular pain successfully treated with a topical formulation of diclofenac, ibuprofe...

keloids are aesthetically disfiguring and severely disabling. the optimal treatment remains undefined. this clinical study, evaluate the efficacy and side effects of combined topical silicone and 5-fluorouracil on the prevention of keloids. in this double blind randomized clinical trial, fifty patients with keloids were randomly allocated in two groups. the control group were treated by periles...

Research was conducted to determine levels of Cry1Ac in transgenic Bacillus thuringiensis Berliner (Bt) cotton leaves from four different commonly used bioassays. Significant differences in the amount of Cry1Ac were found among the different bioassay types. For bioassay arenas that prevented desiccation of leaf material, Cry1Ac levels remained stable for 10 d after tissue was excised from the p...
