Promastigote forms of Phytomonas serpens, Leptomonas samueli, and Leishmania tarentolae express cytoskeletal giant proteins with apparent molecular masses of 3,500 kDa (Ps 3500), 2,500 kDa (Ls 2500), and 1,200 kDa (Lt 1200), respectively. Polyclonal antibodies to Lt 1200 and to Ps 3500 specifically recognize similar polypeptides of the same genera of parasite. In addition to reacting with giant...

OBJECTIVE To assess the quality of life in patients undergoing myocardial revascularization using the six-minute walk test. METHODS Prospective observational study with patients who undergoing CABG. The clinical variables, the sixminute walk test, and the SF-36 test were recorded. The patients were assessed at the preoperative time and at 2 months of postoperative period. According their six-...

In studies with a long-term follow-up, peak expiratory flow (PEF) meters are often used to assess bronchial obstruction. The question arises whether data obtained with these frequently used meters are still reliable after several years of use, and whether the old meters should be renewed after a certain period. In the present study, we tested the reliability of PEF values measured with mini-Wri...

The calibration of pH meters including the pH glass electrode, ISE electrodes, buffers, and the general background for calibration are reviewed. Understanding of basic concepts of pH, pOH, and electrode mechanism is emphasized. New concepts of pH, pOH, as well as critical examination of activity, and activity coefficients are given. The emergence of new solid state pH electrodes and replacement...

Smart meters are assumed to contribute to energy conservation by providing updated consumption data to energy utilities, but, given their pervasive presence in consumers’ homes, they could also provide timely feedback to energy consumers/users. A precondition, however, is that smart meters are really usable to lay consumers. In the present study 40 participants were videorecorded while performi...
