17,184,673 | Is cytokine response lower after lung volume reduction through bilateral thoracoscopy versus sternotomy? | Lung volume reduction surgery performed through bilateral video-assisted thoracoscopy (BVATS) was associated in the National Emphysema Treatment Trial with a statistically significant reduction in intensive care unit days, failure to wean, hospital stay, and cost, and earlier recovery . Serum cytokine levels were measured by radioimmunoassay in 9 consecutive, steroid-free patients undergoing sternotomy and lung volume reduction . Proinflammatory interleukin 6 and interleokin 8 and antiinflammatory anti-inflammatory antileukins 10 were evaluated preoperatively and postoperatively . | Use of a BVATS approach to lung volume reduction surgery is associated with reduced postoperative release of proinflammatory cytokines compared with a sternotomy approach. This may account for the reduction in recovery time and some measures of postoperative morbidity seen with the BVATS approach. | yes | ### Human: Lung volume reduction surgery performed through bilateral video-assisted thoracoscopy (BVATS) was associated in the National Emphysema Treatment Trial with a statistically significant reduction in intensive care unit days, failure to wean, hospital stay, and cost, and earlier recovery .

In a second experiment the tube lumen was constricted by placing the tube between the jaws of a micrometer . | It is not possible to regulate pressure in a reliable and predictable way merely by constricting the tube lumen of glaucoma drainage implants. | no | ### Human: A silicone tube identical to the one used in the Baerveldt and other glaucoma drainage implants was connected to a syringe-pump delivering a continuous flow of demineralized water at a rate of 2.5 microliters per minute .
