The upright posture strengthens the coupling between heart period (HP) and systolic arterial pressure (SAP) consistently with a greater contribution of the arterial baroreflex to cardiac control, while paradoxically decreasing cardiac baroreflex sensitivity (cBRS). To investigate the physiological mechanisms that mediate the coupling between HP and SAP in response to different postures, we anal...
Bromocriptine (Br) was used to test the hypothesis that central dopaminergic mechanisms modulate sympathetic nerve tone, and that when dopaminergic control is deficient there may result enhanced noradrenergic activity and elevated blood pressure (BP) in some patients with primary hypertension. Seven hypertensive patients (age 29 ± 3 years) were studied after a single oral dose of Br (2.5-5.0 mg...
In this paper we present the design and validation of a novel fully embroidered meander dipole antenna-based sensor integrated into commercially available T-shirt for real-time breathing monitoring using technique based on chest well movement analysis. The is made silver-coated nylon thread. proposed antenna-sensor cotton placed middle human chest. was designed to operate at 2.4 GHz. sensing me...
RATIONALE The changes in body position can cause changes in lung function, it is necessary to understand them, especially in the postoperative upper abdominal surgery, since these patients are susceptible to postoperative pulmonary complications. OBJECTIVE To assess the vital capacity in the supine position (head at 0° and 45°), sitting and standing positions in patients in the postoperative ...
[Purpose] The purpose of this study was to examine the reliability and validity of measurements of hip extensor muscle strength using a handheld dynamometer (HHD) with subjects in a sitting position. In doing so, we also aimed to establish a modified method of measurement for patients with flexion contractures in the trunk and lower extremities. [Subjects and Methods] In 20 healthy males, hip e...
The purpose of this investigation was to describe anthropometric and physical performance characteristics of Division I college female lacrosse players. An additional aim of the study was to examine positional differences in this sample of athletes. Eighty-four university lacrosse players (age=19.8+/-1.1 years; height=168.3+/-5.9 cm; body mass=64.7+/-6.9 kg) volunteered to participate and were ...
BACKGROUND The incidence of hematoma formation following implantation of a cardiovascular implantable electronic device (CIED) is estimated to be 5% even if a pressure dressing is applied. It is unclear whether a pressure dressing can really compress the pocket in different positions. Furthermore, the adhesive tape for fixing pressure dressings can tear the skin. We developed a new compression ...
This study aim to investigate the effect of different slops on mechanical lumbosacral angles and lumbar stability of healthy and mechanical low back pain (LBP) persons. This case- control study was performed on 38 females (18 LBP and 20 healthy subjects) who were referred to the Hospital in sari. At the beginning, Subjects’demographic data were recorded. In order to measure lumbosacral angles a...
