Background: Lumbar puncture (LP) is a worth procedure in diagnosis of oncological diseases and intrathecal administration of antineoplastic drugs. The effort should be to minimize pain of LP in children with cancers. This clinical trial was done to compare success rates in performing LP and reducing anxiety and pain of LP in sitting and lateral decubitus positions in 1 to 5-year-old children. ...

BACKGROUND Hypotension is one of the most common complications of spinal anesthesia in parturients undergoing cesarean section. In this regard, the patient's position may affect the incidence of hypotension. OBJECTIVES In this clinical trial, we evaluated the effects of 1- and 2-minute sitting positions versus immediately lying down after spinal anesthesia on hypotension and vasopressor requi...

1. The interaction between ingesta density and gravity observed in the digestive systems of ruminant herbivores should receive attention in other nonruminant herbivorous mammals. The resting postures adopted by non-ruminants are of particular interest. 2. A new interpretation of established findings regarding the digestive tract of sloths illustrates that the interplay of posture, anatomy, the ...

Resumption of daily living activities is a basic expectation for patients provided with total knee replacements. However, there is a lack of knowledge regarding the impact of different activities on the wear performance. In this study the wear performance under application of different daily activities has been analyzed. In vivo load data for walking, walking downstairs/upstairs, sitting down/s...

BACKGROUND Despite the consistent information available on the physiological changes induced by head down bed rest, a condition which simulates space microgravity, our knowledge on the possible perceptual-cortical alterations is still poor. The present study investigated the effects of 2-h head-down bed rest on subjective and cortical responses elicited by electrical, pain-related somatosensory...

Given previous evidence that bodily states can impact basic cognitive processes, we asked whether such impact can also be demonstrated for creative cognition. In particular, we had participants perform a design improvement task and a consequences imagination task while standing up, walking in a predetermined pattern, or walking freely. Results show better divergent-thinking performance with unc...

This paper presents techniques and tools for creating and animating virtual actors in real scenes. Several problems are explained: real objects hidden by virtual actors and virtual actors hidden by real objects, collision detection between the virtual actor and the real environment, correspondence between the real and the virtual cameras, casting shadows of the virtual actors on the real world....

Otolith organs have been shown to activate the sympathetic nervous system in the prone position by head-down rotation (HDR) in humans. To date, otolithic stimulation by HDR has not been comprehensively studied in the upright posture. The purpose of the present study was to determine whether otolithic stimulation increases muscle sympathetic nerve activity (MSNA) in the upright posture. It was h...

BACKGROUND KNOWME Networks is a wireless body area network with 2 triaxial accelerometers, a heart rate monitor, and mobile phone that acts as the data collection hub. One function of KNOWME Networks is to detect physical activity (PA) in overweight Hispanic youth. The purpose of this study was to evaluate the in-laboratory recognition accuracy of KNOWME. METHODS Twenty overweight Hispanic pa...
