Efficacy of thiamethoxam (Cruiser) and imidacloprid (Gaucho) were evaluated as seed treatments for controlling European corn borer, Ostrinia nubilalis (Hübner) and Indianmeal moth, Plodia interpunctella (Hübner) larvae in stored grain. At approximately 22-26 degrees C, all fifth instar European corn borers died after two or 4 d of exposure to corn treated with 250 and 500 ppm thiamethoxam, resp...

Two identical trials, each with 128 crossbred weanling barrows (6.8 +/- .2 and 7.6 +/- .2 kg for Trials 1 and 2, respectively), were conducted. In each trial, pigs were allowed to consume ad libitum a 16% CP corn-soybean meal basal diet (B), B + 55 ppm of carbadox, B + 250 ppm of copper (Cu), or B + 125 ppm of Yucca shidigera extract for 56 d (four pens/diet; eight pigs/pen). At d 56 of the tes...

Inflammation and edema are associated with respiratory and cutaneous exposure to sulfur mustard (SM) as well as with phosgene-induced lung injury. IL-8 is a key inflammatory cytokine that recruits neutrophils linked with the onset and progression of acute lung injury caused by inhalation of these chemical agents. In the present study, human lung small airway cell (SAC) cultures were exposed to ...

Our goal was to study the effectiveness of the insecticide imidacloprid as a systemic control agent. First, to evaluate the blood-feeding effect, we fed adult female Phlebotomus papatasi with imidacloprid-treated rabbit blood and monitored blood-feeding success and survival. Second, to evaluate the feed-through effectiveness of this insecticide, we fed laboratory rats and sand rats with insecti...

In the wake of the findings that Antarctic krills concentrate heavy metals at ppm level, (Yamamoto et al. 1987), the Antarctic waters from the Indian side were examined for the incidence of metal and antibiotic-resistant bacteria during the austral summer (13th Indian Antarctic expedition) along the cruise track extending from 50 degrees S and 18 degrees E to 65 degrees S and 30 degrees E. The ...

Hexane, chloroform and ethyl acetate crude extracts of Atalantia monophylla leaf were studied for ovicidal activity against Helicoverpa armigera at 0.5. 1.0, 2.5 and 5.0% concentrations. The ovicidal activity of 67.10% was statistically significant noticed in hexane extract at 5.0% concentration. The least LC50 value of 2.60% was observed in hexane extract with significant Chi-square value at P...

The anti-feedant and growth inhibitory effects of seed extracts of custard apple in hexane, ethyl acetate and methanol were tested against neonate and 7 days old larvae of the Khapra beetle, Trogoderma granarium, using a feeding bioassay. The LC50 values for hexane, ethyl acetate and methanol extracts were 1195.41, 305.36 and 1446.32 ppm for neonate larvae; 5805, 1300 and 5815 ppm for 7 days ol...

Although ethylene oxide gas is widely used as a sterilizing agent for medical instruments because of its disinfection property, the effects of its use in medical settings have not been clarified. In the present study, we measured the ethylene oxide gas concentration (EOGC) within a hospital sterilization unit and in the ambient air near the unit. Before the sterilizer was turned on (about 9:00)...

AbstractResearch on the antifungal activity test of ethanol extract Kaembu-embu (Blumea balsamifera) leaves against fungus C. albicans growth was carried out. The aim this study to examine extracts albicans. obtained through maceration method. tested for by liquid and solid dilution methods in determining minimum inhibitory concentration (MIC) kill (MKC). results method showed MIC value 25 ppm ...

The aim of this study was to test the effect of fluoride rinsing on the prevention of toothbrush abrasion of softened enamel in situ. For softening, the samples were immersed in 0.1 M citric acid (pH 3.5) for 3 min. Eight test subjects had to make 5 runs in which 4 slabs per run were attached to intraoral appliances. They were as follows: (1) no softening, no fluoride rinsing (control 1); (2) s...
