INTRODUCTION The intensive care unit is one of the specialized units in hospitals where head nurses are responsible for both motivating the personnel and providing high quality care. Understanding of the lived experiences of head nurses could help develop new assumptions of the ICU. The present study was therefore conducted to describe the lived experiences of head nurses working in ICU. METH...

BACKGROUND Premature failure of either the nail and/or locking screws with unstable fracture patterns may lead to angulation, shortening, malunion, and IM nail migration. Up to thirty percent of all unreamed nail locking screws can break after initial weight bearing is allowed at 8-10 weeks if union has not occurred. The primary problem this presents is hardware removal during revision surgery....

Results When Enbrel plus Methotrexate was started she got into remission. After one year of this therapy, she presented uveitis in both eyes, so oral steroids were started again. She obtained only partial ocular improvement, even when she received Infliximab associated with Methotrexate. Meantime she underwent cataract surgery with visus reduction. After one year, Infliximab was suspended becau...

A new low-cost process for fast fabrication of multilayer microfluidic devices using cyclic olefin copolymer film materials is presented. This novel process consists of the fabrication of microfluidic features by xurography, followed by multilayer lamination via cyclohexane vapor exposure. Exposure time to this solvent and compression time were optimized for bond tensile strength. A three-layer...

A migraine attack, a banking crisis or the point of no return for climate change; all these seemingly different phenomena have at least one important thing in common. They suppose the transition from one stable state to another. The climate or the banking system may seem stable and capable of withstanding small or large crises. However, they can deteriorate progressively until reaching a point ...

Computerized molecular models of adenosine triphosphate, adenosine tri-arsenate and adenosine trivanadate have been generated using the molecular mechanics technique. The analysis of structural parameters indicated that, at least theoretically, adenosine triarsenate is a realistic candidate for replacement of adenosine triphosphate in biochemical pathways. On the contrary, the structural arrang...

Background Imaging patients with a pacemaker or AICD has always been taboo in the MRI environment. However, with current improvements in pacemaker lead and generator development along with very vigilant and knowledgeable personnel in pacemaker safety, MRI procedures can be implemented successfully. However, safe performance, not withstanding the risks, leads one to question if the results from ...

Withstanding environmental adversity and seeking optimal conditions for reproduction are basic requirements for the survival of all organisms. Filamentous bacteria of the genus Streptomyces produce a remarkable cell type called the aerial hyphae that is central to its ability to meet both of these challenges. Recent advances have brought about a major shift in our understanding of the cell surf...

Structure determination of proteins and other macromolecules has historically required the growth of high-quality crystals sufficiently large to diffract x-rays efficiently while withstanding radiation damage. We applied serial femtosecond crystallography (SFX) using an x-ray free-electron laser (XFEL) to obtain high-resolution structural information from microcrystals (less than 1 micrometer b...
