|Detection in Environmental Samples of Enteroagregative Escherichia coli, stx-producing Escherichia coli and stx-converting Bacteriophage by RT- PCR: Preliminary Data|
Mura Elia, Noli Alessia Caterina, Rossi Maria Lucia, Terrosu Giovanni, Fadda Antonio
The aim of this work was to collect epidemiological information concerning the presence of Enteroaggregative Escherichia coli, stx-producing Escherichia coli and stx2a-converting bacteriophage, in ruminants faeces.
|METHOD DEVELOPMENT FOR THE SIMULTANEOUS DETERMINATION OF METHYLMERCURY AND INORGANIC MERCURY IN SEAFOOD|
Sergio Carneado, Ariane V. Zmozinski, Carmen Ibáñez-Palomino, Àngels Sahuquillo, José Fermín López-Sánchez, Márcia M. da Silva
This work reports the method development for the simultaneous determination of methylmercury (MeHg+) and inorganic mercury (iHg) species in seafood. The study focused on the extraction and quantification of MeHg+ by liquid chromatography coupled to on-line UV irradiation and cold vapour atomic fluorescence spectroscopy (LC-UV-HG-AFS), using HCl 4 mol L-1 as extractant agent.
|Relationships between Water Quality Constituents in the Delta and the Influence of Different Sources of Water|
Richard A. Denton and Paul Hutton
Analysis of detailed grab sample data from San Francisco Bay and Delta and development of regression relationships between EC, TDS and water quality constituents such as chloride, bromide, sodium, calcium, sulfate, alkalinity and hardness. The relationships in the interior Delta vary depending upon the percentage contributions from seawater, agricultural drainage and freshwater inflows.
|Flow Enhancement and Dynamic of Microfluidic Base Biosensor |
Esmail Abdullah Mohammed Basheer, Hayder A.Abdul Bari
The design of new biosesnor base on microfluidic system is presented. The design is consist of two chips, Microchannels chip and electrodes chip. By varying the size and optimizing the microchannels and electrode, the sensitivity of the biosensor will increase.
|Analysis of Low Levels of Bisphenol A (BPA) in Canned Broths|
Ken G. Espenschied, Michael Ye, Olga I. Shimelis, and Christine Dumas
Bisphenol A (BPA) is a primary monomer used in the manufacture of many plastics and epoxies. Some of these plastics are used as beverage containers and as liners and sealants for metal food containers. Because of BPA’s potential to act as an endocrine disrupter at low concentrations in humans, regulations have been enacted regarding BPA concentrations in food and beverages sold for human consumption.
|Fast and Efficient Analysis of Polynuclear Aromatic Hydrocarbons in Edible Oils Using Dual-Layer SPE|
Christine Dumas and Katherine Stenerson
A new dual-layer cartridge for the efficient extraction of PAHs from edible oils
|Total Phenolics and Beta-1,3-Glucans Extracted from Medicinal Mushrooms (Ganoderma lucidum, Inonotus obliquus, and Phellinus linteus)|
Jaecheol Kim, Kiuk Lee, Keum Taek Hwang(1), Gichun Yoo(2)
This study was to analyze the total phenolics, beta-glucans, and beta-1,3-glucans in water extracts of three medicinal mushrooms (Ganoderma lucidum(GL), Inonotus obliquus(IO), and Phellinus linteus(PL)) under different extraction conditions.
|Microextraction techniques combined with X-ray fluorescence spectrometry for determination of different metal ions in water|
Karina Kocot (a), Beata Zawisza (a), Eva Marguí (b), Ignasi Queralt (c), Rafal Sitko (a)
In present work new preconcentration procedures combining microextraction techniques and X-ray fluorescence spectroscopy were developed. Proposed methodologies are promising tools for multielemental analysis enabling detection of natural pollutants in different water samples.
|HOMOGENEOUS ADCs BEARING TWO DIFFERENT PAYLOADS SHOW STRONG SYNERGY IN TUMOR KILLING|
Lisha Allen, Yi Mi, Muhammad Abbas, Wolfgang Richter, and Sean Hu
We presented a one-pot reaction to prepare site-specific ADCs using available mABs on hand without re-engineering. We have identified a novel non-cleavable linker, which increases not only ADC stability, but also potency. We also demonstrate synergy in cancer cell killing of hybrid ADC loaded with two different toxins
