Abstract: A functional electrical stimulation (FES) device and system. In one embodiment, sequential bipolar pulse stimulation may be provided to an area of a living body via one or more electrode leads applied to the area via a FES device comprising a current pulse generating circuit comprising output nodes for operative coupling to the one or more electrode leads, and configured for operative coupling to a voltage supply. The current pulse generating circuit generally comprises positive and negative stimulation paths drawing from the voltage supply to respectively apply positive and negative currents through the area via the one or more electrode leads. In one example, the stimulation paths comprise respective capacitive elements, a capacitance ratio of which dictating, at least in part, an amplitude ratio of the positive and negative currents, wherein periodic alternative activation of the stimulation paths provides the sequential bipolar pulse stimulation.

Abstract: The invention relates to the use of novel biomarkers and biomarker combinations having utility in the early determination of an individual's critical and/or life threatening response to illness and/or in predicting outcome of said illness. The measurement of expression levels of the products of the biomarkers and combinations of biomarkers of the invention have utility in making the determination of an individual's critical and/or life threatening response to illness. In some embodiments, the biomarker and biomarker combinations are agnostic and are independent of the pre-identification and/or determination of the cause or nature of the illness. In some embodiments, the biomarkers and biomarker combinations can be utilized to select treatment and/or monitor the effectiveness of treatment interventions for an individual who has a critical illness.

Abstract: A Compressed Sensing (CS) based image reconstruction method and system is described herein which may be used to reduce the X-ray dose radiation in Computed Tomography (CT) or to decrease the scan duration in MR imaging (MRI). Methods and systems described herein may address problems that have hindered the clinical usage of CS, i.e. computation complexity and modeling problems. Using the described algorithm, high quality images may be recovered from undersampled data which may help to reduce the scan time and the exposed invasive radiations. Using the same set of data in conventional image reconstruction algorithms (e.g. Filtered Back Projection (FBP) in CT) may cause severe streak artifacts and may take significantly more time using Graphics Processing Units (GPU) and parallel clusters with the conventional CS-based methods. This method can be used other imaging modalities using Radon transform (such as C-Arm and electron tomography, for example).
