Chromium is one of main pollution in sea water, and the establishment detecting kit research hot topic. In this study, immunized mice were obtained by immunogen Cr 3+ -EDTA-BSA, hybridoma strains that secrete -EDTA monoclonal antibody selected. mAb prepared with vivo method. Then, Cr-kit for measurement chromium was developed, its application executed water seafood. Two A321 A424 screened. The ...
Burkholderia pseudomallei, the etiologic agent of melioidosis, is endemic in northern Australia and Southeast Asia and can cause severe septicemia that may lead to death in 20% to 50% of cases. Rapid detection of B. pseudomallei infection is crucial for timely treatment of septic patients. This study evaluated seven commercially available DNA extraction kits to determine the relative recovery o...
Even if the motion of a quantum (quasi-)particle proceeds along a left–rightsymmetric (PT -symmetric) curved path C = R in complex plane C, the spectrum of bound states may remain physical (i.e., real and bounded below). A generalization is outlined. First, we show how the topologically less trivial (tobogganic) contours C may be allowed to live on several sheets of a Riemann surface. Second, t...
We compared root responses of the Ni-hyperaccumulator plant Berkheya coddii Rossler with the non-accumulator plant Cicer arietinum L. to Ni heterogeneity in soil. We grew plants in growth containers filled with control soil, homogeneously spiked, and heterogeneously spiked soil with Ni concentrations of 62 and 125 mg kg(-1). Neutron radiography (NR) was used to observe the root distribution and...
PURPOSE The CellSearch system (Veridex, Warren, NJ) is designed to enrich and enumerate circulating tumor cells (CTCs) from peripheral blood. Here, we validated the analytic performance of this system for clinical use in patients with metastatic breast cancer. EXPERIMENTAL DESIGN This prospective multicenter study conducted at three independent laboratories involved samples from 92 patients w...
This paper introduces a new DNA extraction and purification method from whole blood. Mixing and separation steps are performed using functionalised superparamagnetic beads suspended in cell lysis buffer in a circular chamber that is sandwiched between two electromagnets. Non-uniform nature of magnetic field causes temporal and spatial distribution of beads within the chamber. This process effic...
Heterocyclic amines (HCAs) and acrylamide are unintended hazardous substances generated by heating or processing of foods and are known as carcinogenic and mutagenic agents by the animal experiments. A simple method was established for a rapid and accurate determination of 12 types of HCAs (IQ, MeIQ, Glu-P-1, Glu-P-2, MeIQx, Trp-P-1, Trp-P-2, PhIP, AαC, MeAαC, Harman and Norharman) and acrylami...
