The use of heat treatment for the removal of non-specific effects in the direct radioimmunoassay of human circulatory CEA has been widely adopted have shown the existence of heat-labile determinants on CEA which may be destroyed by this assay technique. Heat-labile antigens appeared to be shared between CEA isolated from tumour and normal colon whilst the heat-stable antigens appeared to be mor...

New developments have dramatically reduced the error currents of IC op amps, especially at high temperatures. The basic techniques used to obtain this peformance are briefly described. Some of the problems associated with working at the high impedance levels that take advantage of these low error currents are discussed along with their solutions. The areas involved are printed-circuit board lea...

can settle in the intestinal tracts and constitute an important part of the indigenous microflora of man and higher animals (Gomes and Malcata, 1999). It exerts a protective role by suppression of pathogenic microorganisms in the intestines and acts as a probiotic (Bergey and Holt, 1994; Gilliland and Speck, 1977; Sandine, 1979). On account of the disturbance of the proliferation and growth of ...

Table 1 on page 231 had a mistake in defining the study group. The research was conducted in two groups instead of three.

A simple and rapid procedure for the determination of plutonium isotopes in the environment is presented. The procedure combines alpha spectrometry, solvent extraction and liquid scintillation measurements to ensure that both alpha- and beta-emitting isotopes are determined. Of five tested extractants, bis-(2-ethylhexyl) phosphoric acid was found to be the best choice. The procedure was applied...

Epidermal bioelectronics, consisting of thin, soft electronic systems that are interfaced with the human body, has started to transform traditional healthcare. Hundreds early versions sensors, actuators and transmitters integrated into patches or bandages deployed in various medical conditions, their number is ever-growing. Among many devices, epidermal biosensors at center this effort offer a ...
