Hong Miao, Yingyi Wang, Xiaoming Yang
Although a number of methods to perform assays of tetracyclines using fluorescent probes have been reported, approaches for discriminating and detecting tetracyclines are few. Herein, bright-blue fluorescent carbon dots (CDs) with a quantum yield (QY) of up to ∼27.9% were hydrothermally synthesized using tobacco as the carbon source. Importantly, the as-prepared carbon dots were employed as a fluorescent probe, enabling selective differentiation of three tetracyclines using a test strip and the related quantitative detection...

Inorganic sulfate is essential for normal cellular function and its homeostasis is primarily regulated in the kidneys. However, little is known about renal sulfate handling in humans and particularly in populations with impaired kidney function such as renal transplant recipients (RTR). Hence, we aimed to assess sulfate reabsorption in kidney donors and RTR. Plasma and urinary sulfate were determined in 671 RTR and in 251 kidney donors. Tubular sulfate reabsorption (TSR) was defined as filtered load minus sulfate excretion and fractional sulfate reabsorption (FSR) was defined as 1-fractional excretion...

Introduction: Acromioclavicular (AC) joint separation is a common entity in athletic patient populations. The surgical treatment of these injuries varies based upon extent of injury, with numerous imaging modalities recommended to differentiate injury severity and treatment options. The use of weighted stress radiographs is controversial in the diagnostic evaluation of AC separation with previous consensus recommending against their use. No study to date has investigated the clinical utilization of diagnostic studies in the evaluation of AC joint separations in a military surgeon population...

Leadership transitions occur frequently, and these times can be challenging for the individual and those they lead. Leaders must develop new knowledge and skills required of the position. Leaders also assume a new formal leadership role over prior peers. This can be a difficult task for junior leaders. The following article illustrates an example case faced by a junior Navy Medical Corps Officer and how one might respond.

SIGNIFICANCE: The authors analyze factors influencing bivariate contour ellipse area (BCEA) in healthy and pathologic eyes and how such factors may affect isolated (static BCEA) or microperimetric fixation (dynamic BCEA). They conclude that aging increases both dynamic BCEA and examination time, whereas static BCEA offers less variance and the maximum distinction with pathologic eyes. PURPOSE: The aim of this study was to assess factors influencing BCEA and the recording method that offer less variability and thus maximum distinction between healthy and pathologic eyes...
