The George Washington University is a private, coeducational research university located in the Foggy Bottom neighborhood of Washington, D.C. The university was chartered by an Act of Congress on February 9, 1821, as the Columbian College in the District of Columbia. In 1904, it changed its name to the George Washington University in honor of George Washington, the first President of the United States. It is the largest institution of higher education in the District of Columbia.The university awards undergraduate and graduate degrees in several disciplines through all of its ten different schools. GWU's Columbian College of Arts and science, School of Business, Elliott School of International Affairs, Milken Institute School of Public Health, School of Engineering and Applied Science, and the School of Nursing offer undergraduate and graduate degrees. The university also has specialized schools within colleges such as the School of Media and Public Affairs and the Corcoran School of the Arts and Design.GWU is consistently ranked by The Princeton Review in the top "Most Politically Active" Schools. Many of the university's graduates have gone on to high positions within both the United States Government and in foreign governments. Notable alumni include US Senate Majority Leader Harry Reid, former Secretary of State Colin Powell, former First-Lady Jacqueline Kennedy, and former FBI Director J. Edgar Hoover. There are currently four George Washington University alumni serving in the United States Senate, nine serving in the United States House of Representatives, and ten serving as United States ambassadors.The sports teams and current and former students in general are called "Colonials".

A catheter can be used in arterial and/or venous placement, in conjunction with ultrasound positioning. The catheter itself is made of the same materials, and is sized using the standard gauges, as current existing catheters. However, the catheter has a microtexture on the outer surface of the catheter. This microtexture efficiently and effectively reflects propagated ultrasound waves in situ, to provide a brighter and clearer image of the catheter when being placed in a patients vessel, with ultrasound imaging equipment.

Systems and methods for visualizing ablated tissue are disclosed. In some embodiments, a system for imaging tissue includes a catheter having an expandable balloon at a distal end, an illumination device positioned within the balloon for propagating light from an external light source for illuminating a tissue being treated to excite native nicotinamide adenine dinucleotide hydrogen (NADH) in the tissue, and an imaging device positioned within the balloon for detecting fluorescence from the illuminated tissue, the imaging device being configured to communicate detected NADH fluorescence to an external fluorescence camera.

Objective The Diabetes Control and Complications Trial (DCCT) was designed to test the glucose hypothesis and determine whether the complications of type 1 diabetes (T1DM) could be prevented or delayed. The Epidemiology of Diabetes Interventions and Complications (EDIC) observational follow-up determined the durability of the DCCT effects on the more-advanced stages of diabetes complications including cardiovascular disease (CVD). Research Design And Methods The DCCT (1982-1993) was a controlled clinical trial in 1,441 subjects with T1DM comparing intensive therapy (INT), aimed at achieving levels of glycemia as close to the nondiabetic range as safely possible, with conventional therapy (CON), which aimed to maintain safe asymptomatic glucose control. INT utilized three or more daily insulin injections or insulin pump therapy guided by self-monitored glucose. EDIC (1994-present) is an observational study of the DCCT cohort. Results The DCCT followed 99% of the cohort for amean of 6.5 years and demonstrated a 35-76% reduction in the early stages of microvascular disease with INT, with a median HbA1c of 7%, comparedwith CONV, with amedian HbA1c of 9%. Themajor adverse effect of INT was a threefold increased risk of hypoglycemia, which was not associated with a decline in cognitive function or quality of life. EDIC showed a durable effect of initial assigned therapies despite a loss of the glycemic separation (metabolic memory) and demonstrated that the reduction in early-stage complications during the DCCT translated into substantial reductions in severe complications and CVD. Conclusions DCCT/EDIC has demonstrated the effectiveness of INT in reducing the long-term complications of T1DM and improving the prospects for a healthy life span. © 2014 by the American Diabetes Association.

A deep vein intravenous introducer has a wheel located toward the front end of the device that can be rotated by the index finger of the user. After placement of the needle in the lumen of the vessel, the user rotates the wheel, which advances the wire guide through the center of the needle and into the patient. Once the guide wire is advanced into the vessel lumen the catheter can be advanced over the guide wire with a hub or finger tab on the catheter close to the index finger. The operation can be performed by one hand without moving the hand from its initial position. The user can then simultaneously use the other hand to operate an ultrasound detection device during insertion without the assistance of another person. A catheter is provided that can be visualized by ultrasound to enable confirmation of correct placement in a vessel. A probe cover is provided that is pre-sterilized and packaged in a cardboard with the top sides of the cover folded down over the cardboard. The cover is placed over the probe end, the sides of the cover are folded up, and the cardboard is removed. The sterile probe cover can be quickly and efficiently placed over the ultrasounds transducer end. Finally, a kit is provided that contains all of the medical devices needed to perform cannulation.

A system and method provides a fault-tolerant multi-channel pulsed plasma thruster system utilizing a control unit and an embedded real time application manipulating low-level timing events with programming, with clear examples of completely flexible control techniques of a scalable micropropulsion system having many pulsed plasma thruster channels, taking into account system aging behavior and specific mission utilization requirements that may change in the mission lifetime. The system and method also covers an architecture lending itself suitable for design of a dedicated FGPA or ASIC that would tightly integrate many channels of thruster components to build a robust, resilient and versatile micropropulsion subsystem for space applications, and indirectly for advanced multi-channel spacecraft instrumentation.
