This work proposes a procedure to estimate the measurement uncertainty for the quantification of cefazolin by high-performance liquid chromatography (HPLC) and microbiological assay (bioassay). HPLC method was performed according to United States Pharmacopeia (USP) and bioassay according to Brazilian Pharmacopeia (FB). The quantification of cefazolin by high-performance liquid chromatography wa...

PubChem's BioAssay database (http://pubchem.ncbi.nlm.nih.gov) is a public repository for archiving biological tests of small molecules generated through high-throughput screening experiments, medicinal chemistry studies, chemical biology research and drug discovery programs. In addition, the BioAssay database contains data from high-throughput RNA interference screening aimed at identifying cri...

Summary The sugarcane whitefly, Neomaskellia andropogonis Corbett (Homoptera: Aleyrodidae), is one of the important pests in Iran. use selective chemical insecticides helps to suppress whitefly infestations. Although several from various groups have been registered control whiteflies, this first study test efficacy deltamethrin, dinotefuran and spiromesifen against eggs, second instar nymphs pu...

Investigations on susceptibility of insecticides in cotton mealybug (Phenacoccus solenopsis Tinsley) was carried out at Main Cotton Research Station, Navsari Agricultural University, Surat during October 2020 to January 2021 through the IRAC leaf dip bio-assay technique. Mealybug population from farmer’s field Bharuch district were collected and reared NAU, under cage cover. Leaf bio-assays for...

objective: this research was carried out as a greenhouse experiment in the form of a completely randomized factorial design (crd) in three-run sequences. the research aimed at investigating the impacts of nicosulfuron (cruz) and rimsulfuran (titus) residues on the growth of wheat in two soil types which differed in their levels of organic compounds and salinity. methods: treatment of the experi...

this study was conducted to investigate commercial formulations of insecticides against western flower thrips, frankliniella occidentalis (pergande).the insects were collected from commercial greenhouses of cucumber in varamin, iran. the tested insecticides were diazinon (ec 60%), cypermethrin (ec 40%), fipronil (ec 2.5%), imidacloprid (sc 35%) and a botanical insecticide oxymatrine (kingbo, as...

Acanthamoeba is an opportunistic protozoan that is widely distributed in the environment and is well recognized to produce serious human infections, including a blinding keratitis and a fatal encephalitis. This review presents our current understanding of the burden of Acanthamoeba infections on human health, their pathogenesis and pathophysiology, and molecular mechanisms associated with the d...

The Organisation for Economic Co-operation and Development has undertaken an international validation program for the rodent uterotrophic bioassay. This validation program comprised two major parts. The first part was the development of a detailed background review document compiling the existing data on the bioassay's history, the molecular and physiologic basis for the bioassay's mechanistic ...

background: crude oil is a very complex composition with harmful effects in human health such as carcinogenesis and blood effects. using the bioassay method to assess the effect of purification process produces useful results. in this study the effect of ozonation to reduce the toxicity of crude oil in the water is investigated. methods: standard sample of the water soluble fraction were prepar...

The ultimate practical goal of pheromone research on insect tsT to place the communication system on a molecular basis and to use the knowledge to detect, survey, trap, or disrupt the population. The ideal procedure is to identify quantitatively all of the components and to use all or some of them as synthesized chemicals in the emitting device in the field. Some of the problems and pitfalls ar...
