Hydrostatic weighing at residual volume and functional residual capacity.
Hydrostatic weighing (HW) was performed at both residual volume (RV) and functional residual capacity (FRC) to determine if underwater weighing at different lung volumes affected the measurement of body density. Subjects were 43 males, 18-25 yr. Subjects were submerged in the prone position, and the lung volume was measured by helium dilution at the time of the underwater weighing. Underwater w...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...

ABSTRACT Background: The current practice to measure RV is either by BPG or helium dilution methods which may not be available in all clinics due to their cost. Methods: This paper outlines a method for both direct and indirect calculation of RV via PFT with acceptable sensitivity (81 %, 60% ), specificity (71 %, 94%) and validity (76%, 78%) for obstructive and restrictive lung disease respect...
متن کاملDietary preparation and per cent fat measurement by hydrostatic weighing.
To examine if the dietary preparation for hydrostatic weighing (HW) alters the % fat measurement, seven men and three women (age 29 +/- 6, Males 11.7 +/- 7.3% fat and Females 24.1 +/- 5.4% fat, mean +/- SD) were assessed before and after three meals. On separate days and in random order, each subject (1) ate a salad with toppings (600 g) with small beverage, (2) ate two bean burritos and one be...

In a plenary session at ASCO 2015, Brown et al. presented the results of Alliance NCCTG N0574, a phase 3 trial comparing whole-brain radiation therapy (WBRT) plus radiosurgery (SRS) to SRS alone in patients with 1 to 3 brain metastases, each <3 cm, by contrast magnetic resonance imaging (MRI). The primary endpoint was cognitive progression (CP), defined as decline >1 standard deviation (SD) fro...
