Insertion sequences (ISs) constitute an important component of most bacterial genomes. Over 500 individual ISs have been described in the literature to date, and many more are being discovered in the ongoing prokaryotic and eukaryotic genome-sequencing projects. The last 10 years have also seen some striking advances in our understanding of the transposition process itself. Not least of these h...

background: the purpose of our study was to assess resident and fellow patient care competency related to chest port catheter insertion after implementation of an educational program and completion of a certification checklist. furthermore, we aimed to measure the impact of this intervention on early infection rates. methods: baseline early infection rates as defined by the cdc were obtained in...

Nowadays, bulk of the designers prefer to outsource some parts of their design and fabrication process to the third-part companies due to the reliability problems, manufacturing cost and time-to-market limitations. In this situation, there are a lot of opportunities for malicious alterations by the off-shore companies. In this paper, we proposed a new placement algorithm that hinders the hardwa...

Umbilical and supraumbilical catheter insertion is a common procedure performed in the NICU. It is a safe and usually easy procedure devoid of serious mishaps, morbidity and mortality. Complications such as hemorrhage, infection, hernia, evisceration, omphalitis, portal vein thrombosis and portal hypertension may occur after umbilical catheter insertion. Other uncommon and rare complications re...

background: intrauterine device (iud) is an effective and long term method of contraception that can be used without continued effort by the user to prevent pregnancy perfectly. pain during iud insertion is one of the obstacles to properly using the device. thus, using different methods of analgesia and anesthesia to alleviate this pain has been studied by many researchers. this review article ...

introduction: transhiatal esophagectomy is a widely accepted approach for palliative resection of subcarinal esophageal cancers. this study was designed to evaluate the necessity of routine thoracostomy tube insertion in this technique.  methods: this descriptive study was conducted on 123 consecutive patients with esophageal cancers undergoing transhiatal esophagectomy from march 2001 to febru...

OBJECTIVE Robotic cochlear implant electrode array insertion offers substantial potential advantages, namely repeatability and minimization of insertion forces, leading to decreased intracochlear trauma. Using such a robotic insertion tool, we sought to analyze force profiles during deployment of stylet-containing electrode arrays using either traditional insertion, in which the stylet is withd...

Herein, the electrochemical performance and mechanism of potassium insertion/deinsertion in orthorhombic V2O5 nanoparticles are studied. The electrode displays an initial potassiation/depotassiation capacity 200 mAh g−1/217 g−1 voltage range 1.5–4.0 V vs. K+/K at C/12 rate, suggesting fast kinetics for insertion/deinsertion. However, quickly fades during cycling, reaching 54 31st cycle. Afterwa...

introduction: to study the long-term complications of tympanostomy tube insertion in young children 10 years after surgery.   materials and methods: in september 2011, the medical records of all patients who had undergone myringotomy with tympanostomy tube insertion between february 2000 and march 2001 at the two general hospitals of isfahan university of medical sciences were studied. of the 9...
