There have been various laboratory methods for the microbiological diagnosis of periodontal disease. However, there have been some disadvantages in these methods. In this study of the application of a chair-side test for microbiological diagnosis, the activity of peptidases in periodontal pockets of patients was examined by using the assay system SK-013. SK-013 consists of synthetic substrates ...

To determine risk factors for restenosis, we studied 998 patients who underwent elective coronary angioplasty (PTCA) to native coronary arteries between July 1980 and July 1984. Restenosis, defined as a luminal narrowing of greater than 50% at follow-up, was present in 302 patients (30.2%). Univariate analysis of 29 factors revealed seven factors related to restenosis: vessel dilated (circumfle...

The suitability of individual MAb for application in vivo should be carefully confirmed. The monoclonal antibody GL-013, with specific binding reactivity in vitro to human tumors of the gastrointestinal tract, was radioiodinated and injected intraperitoneally into nude mice bearing human gastric carcinoma xenografts SY 86 B (moderately differentiated glandular adenocarcinoma) and SY 86 D (signe...

We studied the effect of nitroglycerin-induced decreases in mean arterial pressure (MAP) on myocardial salvage. Two hours after occlusion of the left anterior descending coronary artery, 65 conscious dogs were randomly allocated to receive 4 hr intravenous infusions of saline (group 1, 19 dogs), or nitroglycerin in doses to decrease MAP by 10% (group 2, 18 dogs), 25% (group 3, 14 dogs), and 50%...

We prepared Dy1 xSrxCoO3 (x 1⁄4 0; 0:025) ceramics and evaluated their thermoelectric performances at temperatures up to 873K. The sample in which x 1⁄4 0:025 showed a higher electrical conductivity and a lower Seebeck coefficient than that in which x 1⁄4 0. Due to phonon scattering, the thermal conductivity of the x 1⁄4 0:025 sample was lower than that of the x 1⁄4 0 sample over the entire ran...

Introduction Sarcoidosis is a granulomatous disease possibly affecting all organ systems. Less than 10% of sarcoidosis patients develop symptomatic neurological involvement. Although muscular non-caseating granulomas (NCGs) can be found in up to 75% of sarcoidosis patients, muscular symptoms develop only in less than 0.5% of sarcoidosis patients. Corticosteroids (CS) are the mainstay of medical...

This paper employs a multivariate Bayesian time-varying coetficients (TVC) approach to model and forecast exchange rate data. It is shown that, if used as a data-generating mechanism, a TVC model induces nonlinearities in the conditional moments and leptokurtosis in the unconditional distribution of the series. It is also shown that leptokurtic behavior disappears under time aggregation. As a f...
