Actin has been purified from amoebae of Dictyostelium discoideum by a procedure which is notable in that proteolysis has been diminished to undetectable levels and "selective" purification steps have been avoided. The overall yield of this procedure is 5- to 10- fold greater than that of a previous report (Spudich, J. A. (1974) J. Biol. Chem. 249, 6013-6020). The detailed biochemical and struct...

BACKGROUND Risk factors for poor bowel preparation are recognized to be independent of the type of bowel preparation method used. Patient and administrative factors influencing bowel preparation are known to vary in different healthcare systems. METHODS A prospective, cross-sectional study of patients undergoing colonoscopy in an Asian tertiary centre was conducted to identify risk factors as...

The effectiveness of colonoscopy is highly dependent on the quality of bowel preparation. Although many studies have previously evaluated the role of cleansing methods and dosing regimens, few have examined the association between bowel habits and subsequent bowel preparation. Here, we aimed to evaluate the impact of bowel habits on the quality of bowel preparation.A total of 404 patients who u...

This article aims to describe Vertical Edgeless Preparation (VEP), a full-crown vertical preparation technique initially introduced by the Porta Mascarella Group in 1980s. The method is defined as “periodontally driven” because its main indication teeth with loss of periodontal attachment, and it obtain healthier tissues. work describes step-by-step procedure for performing this prosthetic indi...

In a cross-over study in a group of epileptic patients it was shown that replacement of the evening dose of an ordinary phenytoin preparation with the same phenytoin dose in a delayed-action preparation produced no significant change in the next morning's mean blood phenytoin concentration. However, replacement of the entire daily dose of an ordinary phenytoin preparation with the delayed-actio...

− This paper introduces an alternative method to traditional certified reference material (CRM) preparation technique for microelectronic digital circuits. Instead of selfmanufacturing chips, a novel preparation technique is introduced which selects matured samples as the CRMs, these samples are also called certified reference samples (CRSs). The use of CRS not only greatly reduces the difficul...
