OBJECTIVE To investigate the possible neuroprotective effects of selective cerebral perfusion (SCP) during deep hypothermic circulatory arrest on brain oxygenation and metabolism in newborn piglets. METHODS Newborn piglets 2-4 days of age, anesthetized and mechanically ventilated, were used for the study. The animals were placed on cardiopulmonary bypass, cooled to 18 degrees C and put on SCP...

OBJECTIVE Selective cerebral perfusion (SCP) affords brain protection superior to hypothermic circulatory arrest (HCA) for prolonged aortic arch procedures. Optimal pH strategy for HCA is controversial; for SCP it is unknown. We compared pH strategies during SCP in a survival pig model. METHODS Twenty juvenile pigs (26+/-2.4 kg), randomized to alpha-stat (n=10) or pH-stat (n=10) management, u...

Fused filament fabrication (FFF) has been used to create prototypes and functional parts for various applications using plastic filaments. It also extended the use of continuous fibers reinforcing thermoplastic polymers. This study aims optimize deposition design a coextruded carbon fiber (CCF) composite with polyethylene terephthalate glycol?modified (PETG) filament. The characterizations on r...

Abstract This article analyses whether the emotional intelligence (EI) of street‐level bureaucrats, in this case inspectors, predicts their individual performance. It explores EI aggression that inspectors face and explains relation between Our survey among 547 measuring (self) perceptions, shows inspectors' ability to appraise others' emotions use intelligently (i.e., motivating themselves mai...

The modified waterborne acrylic resin was synthesized successfully by emulsion polymerization with octafluoropentyl methacrylate and phosphate functional monomer as monomers, showing an improved anti-corrosion performance of the coating. existence general distribution elements in were explored, mechanism disclosed. results show that modification monomers water resistance, corrosion resistance t...

It was confirmed that delta 5,7-sterol delta 7-reductase activity was suppressed by cholecalciferol (vitamin D3) in the enzyme system consisted of microsomes and sterol carrier protein (SCP). The enzyme activity was significantly decreased in the combination with microsomes obtained from either vitamin D-deficient or vitamin D3-treated rat liver and with SCP obtained from vitamin D3-treated rat...

During the past 5 years, 30 cases of thoracic aortic aneurysm were treated. Selective cerebral perfusion (SCP) and retrograde cerebral perfusion (RCP) were conducted for cerebral protection during aortic cross clamping. SCP was carried out in 5 cases of dissecting aneurysm (all Stanford type A, including a case of AAE) and 3 cases of arch aneurysm. RCP was conducted in 5 cases of dissecting ane...

Supply chain is the process of continuous flow of products or services from source to the destination. Supply chain management has become an effective tool now a day to survive in this competitive world. Organizations do their best to harvest profits by adopting better supply chain management practices for competitive advantage and organizational performance. In this paper an attempt has been m...

BACKGROUND Selective cerebral perfusion (SCP) is used for extending the period during which surgical procedures can be safely performed. We sought to determine the direct effects of pH management on cerebral microcirculation and metabolism during SCP. METHODS An experimental SCP porcine model was created by selectively allowing cold perfusate only into the bicarotid brachiocephalic trunk duri...
