Permethrin is the most popular synthetic pyrethroid insecticide used in agriculture and public health. For the assessment of human exposure to permethrin, a competitive indirect enzyme-linked immunosorbent assay (ELISA) for the detection of the glycine conjugate of a major metabolite, cis-/trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane-1-carboxylic acid (DCCA), of permethrin was developed...

Harvester ants (Messor galla Forel) defied various control strategies. Two field experiments were conducted to evaluate the effects of Spent Engine-Oil and other nature-based materials on their emergence in Maiduguri, Borno State of Nigeria. The treatments evaluated are spot application of spent engine-oil and some natural materials in experiment 1 and individual and equal mixture of Pure Neem ...

Development of a multianalyte enzyme-linked immunosorbent assay (ELISA) for detection of permethrin and aroclors 1248 or 1254 and implementation of the assay for analysis of soil/sediment samples are described. The feasibility of using the multianalyte ELISA to monitor aroclors 1254 and permethrin simultaneously was tested with permethrin and aroclor standards and with aroclor- and permethrin-c...

A strain of house fly was collected from the Third Yumenoshima Island in Japan and selected with the pyrethroid insecticide permethrin. Resistance to permethrin evolved to >18; 400-fold in the selected (YPER) strain, and the mechanisms and genetics of resistance in this strain were examined. Permethrin resistance was decreased by pretreatment with piperonyl butoxide or 2-propynyl 2,3,6-trichlor...

BACKGROUND The optimal vehicle to ensure adequate penetration of 5-aminolaevulinic acid (ALA) for its use in photodynamic therapy (PDT) of skin lesions has not been determined. OBJECTIVES We aimed to study the effects of ALA in various vehicle formulations [saline lotion with and without dimethylsulphoxide (DMSO), cream, liposomes and vaseline] after topical application in a murine subcutaneo...

Aedes aegypti is the major vector of yellow and dengue fevers. After 10 generations of adult selection, an A. aegypti strain (SP) developed 1650-fold resistance to permethrin, which is one of the most widely used pyrethroid insecticides for mosquito control. SP larvae also developed 8790-fold resistance following selection of the adults. Prior to the selections, the frequencies of V1016G and F1...

A 2-year-and-4-month-old girl suffered a burn to the neck due to boiling water. She was examined at another hospital, and recommended to undergo dermatoplasty. Thirteen days after injury, she consulted our hospital. A wide skin defect was observed around the neck, and a third-degree burn was diagnosed. Conservative treatment using electrolyticreduction ion water (ERI) lotion, antibiotics/steroi...

OBJECTIVES To examine the efficacy of UV photographs and information about photoaging (eg, wrinkles and age spots) for increasing the sun protection intentions and behaviors of young adults and to determine whether any effects of this appearance-based intervention could be enhanced by providing a non-UV alternative for achieving a tan (ie, sunless tanning lotion). DESIGN Randomized control tr...

Sericin as one of two main proteins in silkworm (Bombyx mori L.) cocoons was found to have the ability increase skin moisture cosmetics. The objective this study determine optimal formula sericin nanoparticle lotion and effectiveness lotion. formation nanoparticles mainly carried out by mixing stirring mechanism using urea a crosslinking agent. Temperature speed were fixed, while duration varie...

trasal-contact method test using glass petri-dish rather than the conventional glass jar was used to evaluate the permethrin toxicity and synergism effect of piperonal butoxode (pbo) on nymphae of five strains of blattella germanica (l.). the test was carried out on 2-3 days old of first nympal stage, at four replicates of 10 cockroaches. the susceptible strain showed t50 and kt50 of 12.81 and ...
