    Medical education has adopted various e-learning technologies to its aid. Addition of Google Classroom, introduced in 2014, as a Learning Management System (LMS) has provided a basic, easy to use platform. This study tested its efficacy in teaching a biochemistry module to first year MBBS students in an Indian medical school. Better access to learning material and supplementary teaching resources, helpfulness of immediate feedback, and learning outside of class environment were reported by students. Preference of mobile phone over laptop to access this LMS was reported. Use of this free to use LMS can be made, and especially in resource limited low and middle income countries, to encourage greater access to e-learning. © 2019 International Union of Biochemistry and Molecular Biology, 47(4):404-407, 2019.

    Background: Following contrast-enhanced computed tomography (CECT) contrast-induced nephropathy (CIN) may occur in patients with renal insufficiency or diabetes. Creatinine, the most common marker of CIN, may not be an accurate measure of damage and is affected by many non-renal factors. Our aim was to evaluate ischemia-modified albumin (IMA) as an early CIN marker and correlate it with paraoxonase-1 (PON-1) and creatinine before and after CECT.

    Methods: Forty-eight adult patients scheduled for intravenous CECT, regardless of indication or body region for CECT, were included in this prospective study. Venous blood samples were obtained 12-24 hours before and after contrast media (CM) administration. Ischemia-modified albumin and PON-1 were estimated using methods described by Bar-Or et al. and Dantoine et.al., respectively. Creatinine was estimated on an automated analyzer.

    Results: Significant differences in IMA (P < 0.001) and PON-1 (P < 0.001) levels were found between pre- and post-CECT samples, while the difference for creatinine was not significant (p = 0.073). No correlation was found between IMA and PON-1 or IMA and creatinine in either the pre- or post-CECT samples.

    Conclusion: After CM administration patients are subjected to oxidative stress and/or ischemia, as revealed by elevated IMA and decreased PON-1 levels; however, creatinine levels, most commonly estimated to assess reduced renal function, did not reflect the condition accurately. IMA may be a sensitive marker for CIN but further studies are required to confirm its usefulness.

    The present study was conducted to compare the cleaning efficacy (debris and smear layer removal) of hand and two NiTi rotary instrumentation systems (K3 and ProTaper).
