Three commercial repellents marketed in Tanzania: Zero Bite (a blend of microcrystalline waxes, mineral oils, natural flavours, Olibanum oil, Eucalyptus oil, Geranium oil, Citronella oil and Isopropyl myristrate); X-pel (a petroleum jelly formulation containing diethyl toluamide (DEET) and dimethyl phthalate); No Bite (a spray formulation with diethyl toluamide, 2 methyl 2,4 pentondiol and ptha...

“This idea that a certain level of exposure to a chemical can mean something very different depending on your genetic makeup is quite new and important,” says Shanna Swan, a reproductive health scientist at the Mount Sinai School of Medicine in New York, who was not involved in the study. Small percentages of Europeans and Asians have a genetic mutation that diminishes the production of filaggr...

Dielectric spectra of the beta relaxation in glassy and ultraviscous liquid diethyl phthalate show that its relaxation strength Delta epsilon(beta), the distribution of times, and the relaxation rate are more sensitive to temperature T in the ultraviscous liquid than in the glassy state. The Delta epsilon(beta) against temperature plot has an elbow-shaped break near T(g) of approximately 181 K,...

The chemical composition, antioxidant and antibacterial activities of essential oil from peel of Citrus unshiu which cultivated in South Korea were investigated. Eight compounds were identified as l-limonene (88.11%), γ-terpinene (4.66%), cyclohexane, 2,4-diisopropenyl-1-methyl-1-vinyl (1.82%), diethyl phthalate (1.02%), β-linalool (0.97%), β-myrcene (0.91%), α-farnesene (0.91%) and o-cymene (0...

Propolis is a resinous Bee hive product and has been long used in folk medicine of different nations as early as 3000 BC. Stingless bees are indigenous pollinators of treasured herbal plants. Propolis of stingless bees is a natural, strongly adhesive mixture made of bee secretions and plant resins. Stingless bee Propolis exhibit a wide spectrum of pharmacological activities that vary depending ...

Because of the benzene ring and carbon chain structures, inter-molecular interactions among phthalic acid esters (PAEs) molecules may be significant, but their role in controlling sorption characteristics was not investigated. This work selected diethyl phthalate (DEP) dibutyl (DBP) as model pollutants investigated on biochars produced from chicken feathers (CFBCs). The planar structure CFBCs f...

Many chemically synthesized xenobiotics can significantly inhibit the vitality of parasitic nematodes. However, there is yet too little research on toxicity such contaminating compounds toward Compounds that are present in plants able to organisms as well. According results our laboratory studies toxicity, following caused no decrease larvae Strongyloides papillosus and Haemonchus contortus: me...
