This study examined the effectiveness of a short-duration but high-intensity exercise countermeasure in combination with a novel oral volume load in preventing bed rest deconditioning and orthostatic intolerance. Bed rest reduces work capacity and orthostatic tolerance due in part to cardiac atrophy and decreased stroke volume. Twenty seven healthy subjects completed 5 wk of -6 degree head down...

in a novel dual bed reactor fischer-tropsch synthesis was studied by using two diffrent cobalt catalysts. an alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a rutenuim promoted cobalt catalyst in the second bed. the activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed react...

Prolonged bed rest may cause changes in the autonomic nervous system that are related to cognition and emotion. This study adopted an emotional flanker task to evaluate the effect of 45 days -6° head-down bed rest (HDBR) on executive functioning in 16 healthy young men at each of six time points: the second-to-last day before the bed rest period, the eleventh, twentieth, thirty-second and forti...

Cutaneous vasodilation and sweat rate are reduced during a thermal challenge after simulated and actual microgravity exposure. The effects of microgravity exposure on cutaneous vasodilator capacity and on sweat gland function are unknown. The purpose of this study was to test the hypothesis that simulated microgravity exposure, using the 6 degrees head-down tilt (HDT) bed rest model, reduces ma...

We report a rare case of female patient with metachronous gallbladder cancer and pancreatic head ductal carcinoma. At the age of 53 years, the patient underwent a cholecystectomy and resection of the liver bed for gallbladder cancer. The post-operation diagnosis was a well-differentiated adenocarcinoma with serosa involvement(T3N0M0, stage IIA). Three years later, an irregular and enhanced 2.4 ...

In this paper we demonstrate a driver intent inference system (DIIS) based on lane positional information, vehicle parameters, and driver head motion. We present robust computer vision methods for identifying and tracking freeway lanes and driver head motion. These algorithms are then applied and evaluated on real-world data collected in a modular intelligent vehicle test-bed. Analysis of the d...

The task of public health is to encourage the mother initiate and maintain breastfeeding her child. main proponents early should be pediatricians gynecologists in maternity hospitals. Early "skin-to-skin" contact means that after birth, first ten minutes, newborn placed close with mother. After it born cries, transferred bare chest mother, who comfortably bed head elevated. child a longitudinal...

BACKGROUND Our aim was to investigate the ways in which surgeons who perform head and neck ablative procedures on a regular basis define margins, how they use frozen sections to evaluate margins, and the effect of chemoradiation on determining tumor margins. METHODS A custom-designed questionnaire was mailed to members of the American Head and Neck Society asking members how they evaluate and...
