THIS REVIEW is an attempt to answer two questions. First, are there any isotope technics available at the present time that are really useful in the care of patients? And second, what will be the role of isotope technics in clinical cardiology a few years from now? Historical Review The use of isotopes in clinical cardiology was introduced by Blumgart, Yens, and Weiss, who used radium C and a c...

• A number of new technics involving external detection of radioactivity in the blood stream or in tissues have been proposed as means for determining the rate, volume and pathway of blood flow in the intact subject. By virtue of their dependence on indirect, external measurement of indicator (isotope) activity in the body as opposed to direct measurement, these technics have been categorized a...

N ACCURATE description of the intrinsic renal mechanisms involved in A the excretion of sodium has been difficult to obtain because of the errors inherent in the available experimental technics. Measurements reveal that less than one per cent of the filtered sodium is excreted by man in the normal state of fluid and electrolyte balance (I). Any attempt to define variations of sodium excretion i...

Influenza virus was recovered from aqueous suspensions by means of membrane filters. Separation of virus from bacterial mixtures was achieved and virus was recovered free from bacteria. Technics developed for this application of the use of membrane filters were presented. These technics were extended to the successful isolation of Asian influenza virus from clinical specimens made available for...

conclusions the benson relaxation could reduce pain intensity in women after cesarean section. results the mean of pain score before intervention at cg was 4.43 cm. it was decreased to 4.40 cm (1 min), 4.27 cm (12 h), 4.10 cm (24 h), 4.00 cm (36 h), 3.93 cm (48 h), 3.83 cm (60 h), 3.67 cm (72 h) and 3.51 cm (84 h). meanwhile, the ig was 4.97 cm. it was decreased to 4.90 cm (1 min), 4.23 cm (12 ...

This paper deals with the approximation of semimartingales in finite dimension by dynamical systems. We give trajectorial estimates uniform with respect to the initial condition for a well chosen distance. This relies on a non-expansivity property of the flow and allows to consider non-Lipschitz vector fields. The fluctuations of the process are controlled using the martingale technics initiate...
