The Interaction of a Gemini Surfactant with a DNA Quadruplex.

DNA secondary structures are stabilized by mono- and divalent cations. To examine the stability of the DNA quadruplex formed from (TTAGGG), its interaction with a dicationic Gemini surfactant in standard phosphate buffer was investigated. The Gemini surfactant begins to form micelles in buffer at a (critical micelle concentration) of 1.

Reusable Pulse Oximetry Sensors: A Cost-Saving Quality Improvement Project.

Background: In the setting of tightening health care budgets and capped payments, new strategies are needed to reduce waste while still providing quality and safe care. Transitioning from disposable supplies to reusable options is a viable approach to save money.

Objective: To reduce the cost of the largest expense in the Adult Emergency Department's budget by 20% by transiting from disposable to reusable pulse oximetry sensors.

Structured analysis, evaluation and report of the emergency response to a terrorist attack in Wuerzburg, Germany using a new template of standardised quality indicators.

Background: Until now there has been a reported lack of systematic reports and scientific evaluations of rescue missions during terror attacks. This however is urgently required in order to improve the performance of emergency medical services and to be able to compare different missions with each other. Aim of the presented work was to report the systematic evaluation and the lessons learned from the response to a terror attack that happened in Wuerzburg, Germany in 2016.

[Quality indicators for rescue operations in terrorist attacks or other threats : A pilot study after the Würzburg terrorist attack of July 2016].

Background: Terrorist attacks have become reality in Germany. The aim of this work was, after the Würzburg terrorist attack, to define quality indicators and application characteristics for rescue missions in life-threatening situations. The results can be used to record data from future missions using this template in order to make them comparable with each other.

Piriformis syndrome surgery causing severe sciatic nerve injury.

Piriformis syndrome is a controversial entrapment neuropathy in which the sciatic nerve is thought to be compressed by the piriformis muscle. Two patients developed severe left sciatic neuropathy after piriformis muscle release. One had a total sciatic nerve lesion, whereas the second had a predominantly high common peroneal nerve lesion.
