An Improved Analytical Method for the Determination of Brown FK in Food using HPLC.

In this study, an improved analytical method for the detection of the colorant Brown FK in foods using high-performance liquid chromatography was developed. The method, which employed an RC-C18 column and diode array detection at 254 nm with sodium acetate solution and methanol as mobile phases, exhibited good linearity (R2 = 1.0), and its limits of detection and quantification were determined to be 0.

Use of revascularized artery as a recipient in microvascular reconstruction of the lower leg: An analysis of 62 consecutive free flap transfers.

Background: This study aimed to demonstrate the safety and reliability of combined preoperative angioplasty and free flap transfer in patients with peripheral arterial occlusive disease (PAOD) by analyzing the surgical outcomes.

Methods: Between October 2011 and October 2015, patients who had undergone lower extremity angiography and subsequent free flap transfer were retrospectively reviewed. Data collected included demographics, perioperative data, and postoperative outcomes.

Prediction of the development of late enophthalmos in pure blowout fractures: delayed orbital tissue atrophy plays a major role.

Purpose: To retrospectively evaluate the risk factors for the development of late enophthalmos in pure blowout fractures.

Methods: We reviewed 49 cases of pure blowout fractures diagnosed in Ajou University Hospital, South Korea, from January 2005 to June 2015. We assumed that several factors influence the development of late enophthalmos, including bony defect size, volume of displaced soft tissue, number of fracture sites, involvement of floor, soft tissue incarceration through the bony defect, and patient age.

Clinically significant cardiac arrhythmia in patients with aneurysmal subarachnoid hemorrhage.

Objective: Many previous studies have shown that electrocardiographic (ECG) changes occur patients with subarachnoid hemorrhage (SAH). This study was designed to identify the frequency, influencing factors, and outcome of clinically significant cardiac arrhythmias after SAH.

Methods: We retrospectively analyzed clinical data of 122 patients including ECG finding, age, sex, the Hunt-Hess grade, the Fisher's grade, the history of hypertension, peak blood pressure and heart rate, location of aneurysm, Glasgow Outcome Scale (GOS) score, the days of admission to the intensive care unit, the presence of symptomatic vasospasm.
