The radial flex (R-flex) circuit (previously part no. 18596-60038) has been redesigned and is now available as part no. 18596-60915. This new circuit requires a modified turret (still part no. 18596-60515). “B” trays (18596B) with serial numbers greater than 3032A22099 have the modified turret; therefore, when replacing R-flex circuits on trays with serial numbers below this, check the turret a...

BACKGROUND Whereas the effects of various inspiratory ventilatory modifications in lung injury have extensively been studied, those of expiratory ventilatory modifications are less well known. We hypothesized that the newly developed flow-controlled expiration (FLEX) mode provides a means of attenuating experimental lung injury. METHODS Experimental acute respiratory distress syndrome was ind...

Physically-based atmospheric correction of optical Earth Observation satellite data is used to accurately derive surface biogeophysical parameters free from the atmospheric influence. While water vapor or surface pressure can be univocally characterized, the compensation of aerosol radiometric effects relies on assumptions and parametric approximations of their properties. To determine the vali...

Mammalian cell-based bioprocesses are used extensively for production of therapeutic proteins. Off-line monitoring of such cultivations via manual sampling is often labor-intensive and can introduce operator-dependent error into the process. An integrated multi-functional off-line analyzer, the BioProfile FLEX (NOVA Biomedical, Waltham MA) has been developed, which combines the functionality of...

MOTIVATION Identification of flexible regions of protein structures is important for understanding of their biological functions. Recently, we have developed a fast approach for predicting protein structure fluctuations from a single protein model: the CABS-flex. CABS-flex was shown to be an efficient alternative to conventional all-atom molecular dynamics (MD). In this work, we evaluate CABS-f...

improvements in the properties of ordinary sidewall compound (nr/br) with the addition of epdm by reactive processing method were evaluated. the results show that ozone resistance of these sidewalls was improved with increased addition of epdm. also the tensile strength and elongation-at-break were increased in comparison with nrbrepdm compounds that were made by non-reactive processing. sem ph...

Introduction: The purpose of this in-vitro study was to compare shaping ability of NiTi rotary Mtwo and FlexMaster with stainless steel hand K-Flexofile in curved root canals of extracted teeth. Materials and Methods: Mesiobuccal canals of 45 mandibular molar teeth were balanced into three groups of 15 each, with respect to the Schneider angle, canal access angle, height, dis-tance and radiu...

BACKGROUND Laminectomy/laminotomy and foraminotomy are well established surgical techniques for treatment of symptomatic lumbar spinal stenosis. However, these procedures have significant limitations, including limited access to lateral and foraminal compression and postoperative instability. The purpose of this cadaver study was to compare bone, ligament, and soft tissue morphology following l...

Flex-Het drugs induce apoptosis in multiple types of cancer cells, with little effect on normal cells. This apoptosis occurs through the intrinsic mitochondrial pathway accompanied by generation of reactive oxygen species (ROS). The objective of this study was to determine if direct or indirect targeting of mitochondria is responsible for the differential sensitivities of cancer and normal cell...
