vertical line for standard and motion-guided L+S reconstruction of 12.8-fold accelerated abdominal DCE radial data acquired during free-breathing. The arrows indicate temporal blurring in the standard L+S image and y-t plot, which are removed by the motion-guided L+S approach without loss of spatial resolution. Figure 1: Standard and motion-guided L+S reconstruction of 8-fold accelerated cardia...

More than half of college students self-report some kind anxiety and depression. This study reports how a university course that incorporated structured self-experience practices may reduce symptoms self-reported associated with stress strain. Ninety-eight Junior Senior were enrolled in Holistic Health class focused on “whole-person” curriculum included the exploration psychobiology stress, rol...

We provided in an augmented reality guidance system for liver punctures, which has been validated on a static abdominal phantom. In this paper, we report the first in vivo experiments. We developed a strictly passive protocol to directly evaluate our system on patients. We show that the system algorithms work efficiently and we highlight the clinical constraints that we had to overcome (small o...

Patients with neuromuscular disorders involving respiratory muscles (upper airway muscles, respiratory accessory muscles, diaphragm, even abdominal muscles that stabilize the chest) have more significant problems with breathing during sleep, especially during REM sleep, than during wakefulness. There are means of appropriately treating sleep disordered breathing and improving the quality of lif...

INTRODUCTION For percutaneous abdomen intervention (e.g. liver radiofrequency (RF) tumor ablation, liver biopsy), surgeons lack real-time visual feedback about the location of the needle on planning images, typically computed tomography (CT). One difficulty lies in tracking and synchronizing both the tool movement and the patient breathing motion. AIM To verify the correspondence between rigi...

This article reviews recent research in normal subjects exercising with and without expiratory flow limitation at ,1 L?s imposed by a Starling resistor in the expiratory line, and in patients with chronic obstructive pulmonary disease (COPD), using optoelectronic plethysmography to measure respiratory kinematics, combined with mouth, pleural and abdominal pressure measurements, to assess work o...

Overnight 12 hour tape recordings were made of arterial oxygen saturation (SaO2, pulse oximeter in the beat to beat mode) and abdominal wall breathing movement on 67 healthy, full term infants between the ages of 29 and 54 (median 39) days. The median baseline SaO2 during regular breathing was 99.8% (range 97.0-100%). Fifty four infants (81%) had shortlived episodes during which SaO2 fell to 80...

Breathing was investigated in 14 male subjects with Parkinson's disease and 14 healthy male control subjects. Kinematic, spirometric, acoustic, and pressure data were used to assess function during resting tidal breathing, reading aloud, and monologue production. Data were collected at two times during the drug cycle for subjects with Parkinson's disease. During resting tidal breathing, subject...

Fatiguing expiratory muscle work in otherwise resting humans elicits an increase sympathetic motor outflow; whether limb blood flow ([Formula: see text]) and leg vascular resistance (LVR) are affected remains unknown. We found that fatiguing resistive loaded breathing (ERL) did not affect group mean [Formula: text] or LVR. However, within-breath oscillations may reflect a sympathetically mediat...

The patient was emaciated with a distended abdomen. Answered questions with difficulty. Coughing at intervals with slight expectoration. (Edema of the legs and abdominal wall was present and the patient was markedly ansemic. No sign of jaundice could be detected. The breathing was thoracic in type although a slight movement of the upper part of the abdominal wall was noticeable. There was sligh...
