Methods that have been developed for the potentiometric titration of acidic substances in bitumen with potassium methoxide as the titrant are described. The carboxylic acids and other strong acids are determined by titration in a neutral solvent (a m

Four hydroxyl-substituted benzoic acids and six dihydric phenols have been titrated potentio-metrically in n-butylamine solution using potassium methoxide as the titrant. The results are discussed in terms of the electron-attracting and electron-repe

A potentiometric technique is described which is suitable for the estimation of carboxylic acids in a ‘neutral’ solvent, such as a mixture of benzene and methanol, and for the estimation of weaker acids, such as phenols, in basic solvents such as

Hearing impairment impacts on the lives of almost half of people over the age of 65. For many people, a hearing aid or other assistive device can enhance communication. However, there is a high rate of dissatisfaction with hearing aids among those wh

SUMMARYThe C5a receptor is expressed by a variety of cell types. These studies demonstrate by immunohistochemistry that the receptor is present on the surface of proximal and distal tubular epithelial cells from normal kidney. In addition, the recept

The frequent variations of human complement component C4 gene size and gene numbers, plus the extensive polymorphism of the proteins, render C4 an excellent marker for major histocompatibility complex disease associations. As shown by definitive RFLP

Complete deficiency of the complement C4A isotype is a known genetic risk factor for systemic lupus erythematosus (SLE). The disease phenotype of C4A-deficient patients has never been defined. Among 200 patients with SLE from five centers, 18 (9%) wi

Continuous arteriovenous hemofiltration is a form of renal replacement therapy whereby small molecular weight solutes and water are removed from the blood via convection, alleviating fluid overload and, to a degree, azotemia. It has been used in many
