A two-year study was carried out on human subjects of various ages and backgrounds who had been drinking water containing more than 0.05 mg/liter (0.05 ppm) arsenic for a period of at least five years. The main aim was to correlate the frequency of chromosome aberrations and sister chromatid exchanges in the lymphocytes with the amount of arsenic in the(More)
Apolipoprotein J (apoJ) is an abundant glycoprotein in many biological fluids, and its constitutive high level synthesis is characteristic of many epithelial cells exposed to harsh fluids such as urine, bile, and gastric secretions. In addition, dramatic induction of apoJ occurs in cells surrounding several kinds of pathological lesions. Because platelets(More)
OBJECTIVE We investigated the propagation of viral-size particles by lymph and blood after subcutaneous injection. METHODS In the canine model, transport of [99mTc] sulfur colloid particles of different sizes was studied in different settings in venous blood and lymph for 45 minutes after inoculation. RESULTS The mean arrival time of particles in the(More)
Apolipoprotein J (apoJ) defines a heterogeneous subclass of human plasma high-density lipoproteins (HDL) having a bimodal distribution of molecular mass of 70-90 kDa (approximately 50%) and 200 kDa or larger (approximately 50%). ApoJ-HDL are unstable in stored plasma, and must be evaluated within 24 h. All apoJ-HDL in freshly obtained plasma have alpha 2(More)
Electrochemical enzyme immunoassay methodology has been developed to take advantage of the selectivity of antibody reactions, the amplification feature of an enzyme-based assay, and the ease with which small amounts of the enzyme-generated product can be detected electrochemically. A heterogeneous sandwich enzyme immunoassay was used in this work as the(More)
The generally accepted method of preserving donor heart integrity during transfer is to arrest it with cold cardioplegic solution, then store it in a plastic bag immersed in an iced electrolyte solution. Temperatures between 0 degree C and 4 degrees C are maintained by this method until the heart is transplanted. Although profound hyperthermia best inhibits(More)
Isolated working rat hearts, receiving no drug treatment, recovered low values of contractile function after 33 min of zero-flow global ischemia and 30-min reperfusion, had lower ATP and creatine phosphate (CrP) values in the subendocardium than in the subepicardium after reperfusion (subendocardial/subepicardial ratio ATP = 0.44, CrP = 0.45), and had a(More)
An electrochemical method has been developed for determining NADH in whole blood for dehydrogenase-based assays by flow-injection analysis. NADH generated by dehydrogenase is oxidized by an electron-transfer coupling reagent, 2,6-dichloroindophenol (DCIP). The reduced form of DCIP (DCIPH2) is measured amperometrically by flow-injection analysis. Endogenous(More)
