Purpose: Physiological changes during pregnancy impose numerous changes on the respiratory system that can affect the health of both mother and fetus. Regarding the importance of the normal breathing in the health of mother and fetus, this study aimed to investigate the effect of breathing exercise on breathing pattern of pregnant women.  Methods: The study population was pregnant women...

Since the introduction of this test by Hermannsen (1933), the measurement of maximum breathing capacity (M.B.C.) on different groups of subjects has been reported on several occasions (for example, Gray and Green, 1945; Baldwin, Cournand, and Richards, 1948; Wright, Yee, Filley, and Stranahan, 1949; and Gilson and Hugh-Jones, 1949). Most investigators have performed this test with a spirometer,...

CONTEXT The standard doses of (13)C-urea in (13)C-urea breath test is 75 mg. OBJECTIVE To assess the diagnostic accuracy of (13)C-urea breath test containing 25 mg of (13)C-urea comparing with the standard doses of 75 mg in the diagnosis of Helicobacter pylori infection. METHODS Two hundred seventy adult patients (96 males, 174 females, median age 41 years) performed the standard (13)C-urea...

Objectives: Dynamic Neuromuscular Stabilization (DNS) approach evaluates and activates the spinal stabilizers to optimize the performance of posture and respiratory system. This study investigated the effects of DNS breathing exercises on upper and lower chest wall mobility (UCM and LCM), trunk extensor endurance, and thoracic kyphosis in a group of sedentary students with poor posture. Method...

All DHI test-day data, including milk urea concentrations measured by infrared test method, were collected from 60 commercial Ontario Holstein dairy herds for a 13-mo period between December 1, 1995, and December 31, 1996. The objectives of this study were to describe the relationships between milk urea concentrations and seasonal factors, sampling factors, cow factors, and test-day production ...

Breathing against a continuous positive or negative pressure has been demonstrated to alter urine flow. Continuous positive pressure breathing is associated with a decrease in the rate of urine flow in dog (1) and man (2), whereas breathing against a constant negative pressure produces an increased rate of urine flow in the same species (1, 3). A decrease in urea clearance accompanies the antid...
