Peripartum Hyperkalemia Caused by Magnesium Infusion in a Woman With End-Stage Renal Disease: A Case Report.

Pregnancy in the setting of renal failure has higher rates of adverse events necessitating increased monitoring and treatment. Pregnant women with end-stage renal disease have higher rates of hypertension, and 50% of pregnancies are complicated by preeclampsia. We describe the case of a 32-year-old parturient with end-stage renal disease on hemodialysis with superimposed preeclampsia who developed clinically significant hyperkalemia with electrocardiographic changes after magnesium infusion.

Myosin light chain kinase mediates transcellular intravasation of breast cancer cells through the underlying endothelial cells: a three-dimensional FRET study.

The transient and localized signaling events between invasive breast cancer cells and the underlying endothelial cells have remained poorly characterized. We report a novel approach integrating vascular engineering with three-dimensional time-lapse fluorescence resonance energy transfer (FRET) imaging to dissect how endothelial myosin light chain kinase (MLCK) is modulated during tumor intravasation. We show that tumor transendothelial migration occurs via both paracellular (i.

Prospective phase II trial of concomitant boost radiotherapy for stage II nasopharyngeal carcinoma: an evaluation of response and toxicity.

Introduction: Stage II nasopharyngeal carcinoma (NPC) treated with conventionally fractionated radiotherapy results in loco-regional control of around 80%. This report aims to document the outcome of Stage II NPC patients treated with external beam radiotherapy delivered using an accelerated concomitant boost (C-Boost) schedule.

Methods And Materials: Twenty-five 1997 AJCC Stage II NPC patients were enrolled and analyzed in this preliminary report.
