The recent paper by Rotimi and colleagues 1 does not mention the acridine orange stain 2 when comparing staining methods for the identification of Helicobacter pylori. The acri-dine orange stain uses ultraviolet fluores-cence in the identification of bacteria. The typical curved morphology of H pylori can easily be diVerentiated from other bacteria. I have used this quick, cheap, and reliable s...

The traceability system of navel orange can ensure the quality and safety due to the whole process control from orchard to market. Research on the whole process of navel orange is the foundation and premise of building the traceability system. Based on the analyses of whole food chain of navel orange from origin to market, HACCP is used to evaluate the risk and latent risk of the food chain of ...

Marked elevation of dioxin associated with the herbicide Agent Orange was recently found in 19 of 20 blood samples from persons living in Bien Hoa, a large city in southern Vietnam. This city is located near an air base that was used for Agent Orange spray missions between 1962 and 1970. A spill of Agent Orange occurred at this air base more than 30 years before blood samples were collected in ...

W. Barros-Parada, A.L. Knight, E. Basoalto, and E. Fuentes-Contreras. 2013. An evaluation of orange and clear traps with pear ester to monitor codling moth (Lepidoptera: Tortricidae) in apple orchards. Cien. Inv. Agr. 40(2):307-315. Studies were conducted to evaluate the use of several trap-lure combinations to improve the monitoring of codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricid...

This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...

Abstract--Orange G was given to groups of three male and three female pigs for 112 days at doses of 0 (control), 2"5, 25 or 250 mg/kg/day. No adverse effects were found in pigs given 2"5 mg Orange G/kg/day. At the higher levels, Heinz bodies were found in the erythrocytes, together with anaemia, reticulocytosis, splenomegaly and, at the highest level only, a histologically demonstrable increase...

a simple, economical, precise and fast visible spectrophotometric method has been developed for the determination of azathioprine in tablet dosage form. developed method is based on the formation of extractable colored complex of drug with colouring agent indigo carmine and methyl orange. a wavelength maximum was found to be 683.7 nm and 566 nm. the concentration range of 15-50 μg ml-1 with of ...

An innovative way to fix preformed nanocrystalline TiO(2) on low-density polyethylene film (LDPE-TiO(2)) is presented. The LDPE-TiO(2) film was able to mediate the complete photodiscoloration of Orange II using about seven times less catalyst than a TiO(2) suspension and proceeded with a photonic efficiency of approximately 0.02. The catalyst shows photostability over long operational periods d...
