Thermobarometry suggests that ultrahigh-pressure (UHP) to high-pressure (HP) rocks across the Western Gneiss Region ponded at the Moho following as much as 100 km of exhumation through the mantle and before exhumation to the upper crust. Eclogite across the c. 22 000 km study area records minimum pressures of c. 8–18 kbar and temperatures of c. 650–780 C. One orthopyroxene eclogite yields an UH...

BACKGROUND Severe cardiogenic pulmonary edema is a frequent cause of respiratory failure, and many patients with this condition require endotracheal intubation and mechanical ventilation. We investigated whether continuous positive airway pressure delivered by means of a face mask had physiologic benefit and would reduce the need for intubation and mechanical ventilation. METHODS We randomly ...

this study was an attempt to analyze the applications and problems of conducting blended learning (bl) in view point of the agricultural students from bu-ali sina university. the study has employed a surveying methodology with interviewing and included a combination of descriptive and quantitative research methods. statistical population of the study included 500 agricultural students from bu-a...

background: stress and anxiety in cancer patients are caused by disease diagnosis, unfamiliar experiences, and therapy-related problems. in addition to the short duration of radiotherapy, receiving and understanding of the information about this treatment could be difficult for patients due to anxiety, fatigue, and mental pressure. training of cancer patients about radiotherapy via educational ...

The influence of the sympathetic nervous system on the cerebral circulatory response to graded reductions in mean arterial blood pressure was studied in anesthetized baboons. Cerebral blood flow was measured by the 133Xe clearance method, and arterial blood pressure was decreased by controlled hemorrhage. In normal baboons, the constancy of cerebral blood flow was maintained until mean arterial...

BACKGROUND Death rates due to hypertension in low and middle income countries are higher compared to high income countries. The present study is designed to combine life style modification and home blood pressure monitoring for control of hypertension in the context of low and middle income countries. METHODS The study is a two armed, parallel group, un-blinded, cluster randomized controlled ...

OBJECTIVE To assess the relation between blood pressure control and the following: the Morisky-Green test, the patient's consciousness regarding high blood pressure, the patient's attitude in face of medicine intake, the patient's attendance at medical consultations, and the subjective physician's judgment. METHODS We studied 130 hypertensive patients with the following characteristics: 73% f...

BACKGROUND Elderly family caregivers are presumed to be susceptible to having various health problems. However, biomedical indicators of health in these caregivers are rarely examined. OBJECTIVE To examine the effect of sleep quality, measured by hours of sleep and the number of times leaving bed, on various blood pressure parameters in elderly caregivers. DESIGN Observational study. SETT...

N Engl J Med 2007;357:e4. Copyright © 2007 Massachusetts Medical Society. Indications Providing positive-pressure ventilation with a face mask and a bag-valve device can be a lifesaving maneuver. Although seemingly simple, the technique requires an understanding of the airway anatomy, the equipment, and the indications. Face-mask ventilation is used in patients who have respiratory failure but ...
