This paper proposes the concept of Co-Habited Mixed Reality, and argues how it serves as a basis for large-scale social interaction systems and communityware. The technology that it implies is aimed at focusing a large potential for interaction such that eeectiveness of participation to large scale events is enhanced. We illustrate the idea with scenarios from an ongoing project (COMRIS: co-hab...

conclusion the high discriminative power of hsp65 pattern particularly hpaii digestion, provide an exact and costeffective method for rapid identification of m. simiae strains among registered pulmonary cases. results of 962 culture positive specimens, 17(1.7%) were identified as m. simiae species; majority of them were multidrug-resistance (12; 70.5%). the overall detection rate by tb11, tb12 ...

A new bioassay method for measurement of angiotensin II was clinically applied to determine the plasma renin activity (PRA) in normal subjects and hypertensive patients. Angiotensin II was extracted by a modified procedure reported by Boucher et al. Levels of angiotensin II extracted from 17 blood samples were independently determined by our new bioassay method and the rat pressor assay. The ne...

BACKGROUND The measurement of renin activity is complicated by difficulties in the quantification of angiotensin 1 (Ang1), the product of the renin-catalyzed reaction. We report an HPLC-electrospray-tandem mass spectrometry (HPLC-ESI-MS/MS) method for the quantification of Ang1 as a measure of plasma renin activity (PRA). METHODS After incubation (37 degrees C for 3 or 18 h), samples were pre...

Background and objectives: Coumarins have potential anticancer effects. Ferulago macrocarpa (Fenzl) Boiss, is a perennial herb which has shown to have several dihydropyranocoumarins like grandivittin (GRA) and dihydrofuranocoumarins such as prantschimgin (PRA). Previously the antibacterial, cytotoxic and antioxidant effect of GRA and PRA have been reported. Understandi...

The purpose of this investigation was to assess the effects of acute hypoxia on left (LV) and right ventricular (RV) contractility in clinically stable chronic obstructive pulmonary disease (COPD) patients. Eleven male patients (mean age 52.4 +/- 12.6 years) who were diagnosed to have COPD were included into the study. All of the patients underwent left and right heart catheterization. RV contr...

Background. Laparoscopic lateral transperitoneal adrenalectomy (LTA) has been the standard method for resecting benign adrenal gland tumors. Recently, however, laparoscopic posterior retroperitoneal adrenalectomy (PRA) has been more popular as an alternative method. This systematic review evaluates current evidence on adrenalectomy techniques, comparing laparoscopic LTA with PRA and laparoscopi...

A semi-micro method for determination of plasma renin activity (PRA) by radioimmunoassay of generated angiotensin I (AI) is described. The method permits measurement of PRA on 250 mul of plasma without loss of specificity, sensitivity, accuracy or preision. The small sample size has considerable application in terms of investigation of infants and young children. A reference range was establish...

Featured Article: Fyhrquist F, Soveri P, Puutula L, Stenman U-H. Radioimmunoassay of plasma renin activity. Clin Chem 1976;22:250 – 6. In the early 1970s there was a growing need for reliable and clinically useful methods for the determination of the activity of the renin-angiotensin system. Bioassay methods for renin activity, although valuable in early research, were too cumbersome and unreli...

INTRODUCTION The accuracy and practicality of PCR-restriction endonuclease analysis (PRA) for rapid identification of pathogenic rapidly growing mycobacteria (RGM) isolates were evaluated. MATERIALS AND METHOD PRA identification using an amplified 439-bp segment (amplicon) of the 65-kDa heat shock protein gene was compared to identification by conventional methods, for 39 clinically significa...
