Translation is carefully regulated to control protein levels and allow quick responses to changes in the environment. Certain questions about translation in vivo have been unattainable until now. In this issue, Pichon et al. (2016. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201605024) describe a new technique to allow real-time monitoring of translation on single mRNAs.

Technical innovations in brain tumour diagnostic and therapy have led to significant improvements of patient outcome and recurrence free interval. The use of technical devices such as surgical microscopes as well as neuronavigational systems have helped localising tumours as much as fluorescent agents, such as 5-aminolaevulinic acid, have helped visualizing pathologically altered tissue. Nonetheless, intraoperative instantaneous frozen sections and histological diagnosis remain the only method of gaining certainty of the nature of the resected tissue. This technique is time consuming and does not provide close-to-real-time information. In gastroenterology, confocal endoscopy closed the gap between tissue resection and histological examination, providing an almost real-time histological diagnosis. The potential of this technique using a confocal laser endoscope EndoMAG1 by Karl Storz Company was evaluated by our group on pig brains, tumour tissue cell cultures, and fresh human tumour specimen. Here, the authors report for the first time on the results of applying this new technique and provide first confocal endoscopic images of various brain and tumour structures. In all, the technique harbours a very promising potential to provide almost real-time intraoperative diagnosis, but further studies are needed to provide evidence for the technique’s potential.

AbstractTimely pipeline leak detection is a significant business issue in view of a long history of catastrophic incidents and growing intolerance for such events. It is vital to flag containment loss and location quickly, credibly, and reliably for all green or brown field critical lines in order to shut down the line safely and isolate the leak. Pipelines are designed to transport hydrocarbons safely; however, leaks have severe safety, economic, environmental, and reputational effects. This paper will highlight robust, reliable, and cost-effective methods, most of which leverage real-time instrumentation, telecommunications, SCADA, DCS, and associated online leak detection applications. The purpose of this paper will be to review the underlying leak detection business issues, catalogue the functional challenges, and describe experiences with available technologies. Internal and external techniques will be described, including basic rate of change of flow and pressure, compensated mass balance, statistical, real-time transient modeling, acoustic wave sensing, fiber optic cable (distributed temperature, distributed acoustic sensing), and subsea hydrophones. The paper will also describe related credibility, deployment, organizational, and maintenance issues with an emphasis on upstream applications. The scope will include leak detection for pipelines conveying various flowing fluids—gas, liquid, and multiphase flow. Pipeline environments will include subsea and onshore. Advantages, disadvantages, and experiences with these techniques will be described and analyzed.
