    Direct electrical bipolar electrostimulation for functional cortical and subcortical cerebral mapping in awake craniotomy. Practical considerations.
    Neurochirurgie 2017 Feb 2. Epub 2017 Feb 2.
    Department of Neurosurgery, Sainte-Anne Hospital, Paris, France; Paris Descartes University, Sorbonne Paris Cité, Paris, France.
    Introduction: The aim of brain glioma surgery is to maximize the quality of resection, while minimizing the risk of sequelae. Due to the frequent location of gliomas near or within eloquent areas, owing to their infiltrative feature, and because of major interindividual variability, the anatomofunctional organization and connectivity must be studied individually. Therefore, to optimize the benefit-to-risk ratio of surgery, intraoperative functional mapping is extensively used. Read More

    The acquisition of mechano-electrical transducer current adaptation in auditory hair cells requires myosin VI.
    J Physiol 2016 Jul 27;594(13):3667-81. Epub 2016 May 27.
    Sussex Neuroscience, School of Life Sciences, University of Sussex, Falmer, Brighton, BN1 9QG, UK.
    Key Points: The transduction of sound into electrical signals occurs at the hair bundles atop sensory hair cells in the cochlea, by means of mechanosensitive ion channels, the mechano-electrical transducer (MET) channels. The MET currents decline during steady stimuli; this is termed adaptation and ensures they always work within the most sensitive part of their operating range, responding best to rapidly changing (sound) stimuli. In this study we used a mouse model (Snell's waltzer) for hereditary deafness in humans that has a mutation in the gene encoding an unconventional myosin, myosin VI, which is present in the hair bundles.

    Piezo1 haploinsufficiency does not alter mechanotransduction in mouse cochlear outer hair cells.
    Physiol Rep 2016 Feb;4(3)
    Department of Biomedical Science, University of Sheffield, Sheffield, UK
    The mechanoelectrical transducer (MET) channels located at the stereocilia tip of cochlear hair cells are crucial to convert the mechanical energy of sound into receptor potentials, but the identity of its pore-forming subunits remains uncertain. Piezo1, which has been identified in the transcriptome of mammalian cochlear hair cells, encodes a transmembrane protein that forms mechanosensitive channels in other tissues. We investigated the properties of the MET channel in outer hair cells (OHCs) of Piezo1 mice (postnatal day 6-9). Read More

This could be for example in the short-term care of people with diabetes, people who have insensate feet and people with poor blood supply to the foot coupled with plantar ulceration. The aim of the study was to investigate which type and thickness of Hapla felt padding is the most effective at redistributing plantar pressure of the foot. Read More

    [Determination of 32 sulfonylurea herbicide residues in sweet corns and green soybeans by QuEChERS-liquid chromatography-tandem mass spectrometry].
    Se Pu 2015 May;33(5):501-7
    A fast method based on QuEChERS methodology for the simultaneous determination of 32 sulfonylurea herbicide residues in sweet corns and green soybeans was developed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The clean-up effects of three dispersive sorbents were evaluated in terms of the residue mass for extracts after evaporation and recoveries. The three sorbents were C18, a mixture of two sorbents--silica coated with zirconium dioxide (Z-Sep) and C18, a bonded C18 zirconia-coated silica (Z-Sep+). Read More
