The "Tehran Blood Pressure Study" (TBPS) is an observational cross-sectional study performed on men and women aged 15 years or more during the years 1990-1991. The study has been designed and performed by the Tehran University of Medical Sciences' Cardiovascular Research Center, with the primary objective of determining the prevalence and distribution of high blood pressure in Tehrani adult...

A high-pressure dilatometer capable of measuring volume changes of 2 X loo6 cm3 is described. Fractional volume changes of 1 part in lo4 can be measured over a temperature range of 30-90 “C, and a pressure range of 1 bar (0.1 MPa)-3 kbar (300 MPa). The dilatometer is constructed out of a commercial high-pressure valve and a compact home-built pressure sensor. The system was specially designed t...

Since the late 1950's, high-pressure structural studies have become increasingly frequent, following the inception of opposed-anvil cells, development of efficient diffractometric equipment (brighter radiation sources both in laboratories and in synchrotron facilities, highly efficient area detectors) and procedures (for crystal mounting, centring, pressure calibration, collecting and correctin...

An isocratic reversed-phase high-pressure liquid chromatographic method for the determination of six components of the teicoplanin complex in biological fluid was developed. By using fluorescence detection after precolumn derivatization with fluorescamine, the assay is specific and highly sensitive, with reproducibility studies yielding coefficients of variation ranging from 1.5 to 8.5% (at 5 t...
