Abstract: The present invention provides new evidences to support that repetitive peripheral magnetic stimulation (theta-burst en stimulation, TBS) over nerve/muscle improves sensorimotor control. Chronic low back pain (CLBP) is associated to a faulty volitional activation of transversus abdominis muscle (TrA) and its delayed contraction during anticipatory postural adjustment (APA), in correlation with maladaptive reorganization of primary motor cortex (M1). Repetitive magnetic stimulation of nerves can influence brain excitability and even reduce rigidity (Parkinson's disease), spasticity (stroke, ABI, cerebral palsy), and contribute to improvement of motor-control and function in stroke, chronic low back pain, ABI, cerebral palsy, prematurity and Parkinson's disease.
Abstract: There is provided a method for referencing and correcting the beating spectrum generated by the interference of the components of a frequency comb source. The proposed method allows monitoring of variations of a mapping between the source and the beating replica. This can then be used to compensate small variations of the source in Fourier transform spectroscopy or in any other interferometry application in order to overcome the accuracy and measurement time limitations of the prior art. Constraints on source stability are consequently reduced.

Abstract: AKR1B1 (EC 1.1.1.21) is an aldose reductase that has mainly been associated with the polyol pathway, and more recently with lipid deperoxidation. We have discovered that the primary activity of this enzyme is rather a PGFS activity, catalyzing the transformation of PGH2 into PGF2?. AKR1B1 as a therapeutic target, and method for modulating its expression and activity are provided. Methods for regulating the expression and activity of PGF2? are also provided.

Abstract: The present invention relates to compounds and methods for modulating, reducing or inhibiting, inflammatory reactions in a patient. Particularly, inflammatory reactions that are targeted by the present invention are cell migration, secretion of toxic products and proteolysis at a site of inflammation. Reduction of inflammation manifestations and reactions occurs by using an anti-S100 polynucleotide or polypeptide inhibitor or antagonist, which is essentially targeted against S100A8, S100A9 or S100A12, alone or in combination with other inhibitors of chemokines or immune modulating products.
Abstract: Reagents, methods and kits for screening for compounds that modulate the activity of voltage-gated sodium channels (NaV), such as human NaV1.5/SC-N5A/hH1 are described. The reagents, methods and kits are based on mutated NaV alpha subunit polyptides of SEQ ID NO:5 with mutations at positions 372, 898, 1419 and 1711 (the DEKA motif) and at positions 11485, 1486 and 1487 (the IFM motif) resulting in increased permeability for a group IIA divalent cation (Ca++) and decreased inactivation rate. The mutant polypeptide is used in a method and kit for determining whether a test compound modulates the channel activity, preferably using a chimeric polypeptide (chameleon polypeptide) comprising calmodulin, a calmodulin binding protein (M13), and two fluorescent agents.

Abstract: A method of inferring intentions of an operator to move a robotic system includes monitoring the intention of the operator, with a controller. The intention of the operator is inferred to be one of a desired acceleration and a desired deceleration. The intention of the operator is also as a desired velocity. Admittance parameters are modified as a function of at least one of the inferred acceleration, deceleration, and velocity.

Abstract: System and method for converting kinetic energy from a fluid flow into mechanical energy, the method comprising the steps of: a) providing a turbine including first and second hydrofoils, each of the hydrofoils being able to move lin-early in a heaving motion, and being able to oscillate about a spanwise axis in a pitching motion, said heaving and pitching motions being quasi-si-nusoidal, b) coupling the heaving motions of the first and second hydrofoils to the pitching motions of the second and first hydrofoils respectively, with the pitch-heave motion phase being substantially equal to the inter-hydrofoil phase, the heaving motion of one of the hydrofoils thereby driving the pitching motion of the other hydrofoil; and c) transforming the heaving motions of the hydrofoils into a rotational movement of a rotatable shaft, with linear-to-rotary transmission means.

Abstract: A method for writing a Bragg grating in a glass optical waveguide is provided. Ultrafast optical pulses are generated, preferably in the femtosecond range and having a writing wavelength in the range of 300 nm to 700 nm and an intensity sufficient to induce a change of refractive index in the waveguide through densification. The optical pulses are diffracted using a phase mask, to generate an interference pattern having a pitch providing a fundamental Bragg resonance corresponding to the target wavelength to be reflected by the grating. The interference pattern is impinged on a region of the waveguide, which is heated to a temperature above a threshold and for a predetermined heating period. Advantageously, the heating step allows the reduction of photoinduced losses which would otherwise be present in the waveguiding properties of the waveguide. Optionally, gratings may be written through the polymer jacket of an optical fiber.
Abstract: Purpose. The relationship between inherited genetic variations in 5?-reductase type 1 (SRD5A1) and type 2 (SRD5A2) genes and the risk of biochemical recurrence after radical prostatectomy (RP) in prostate cancer (PCa) remains a fairly unexplored area of research. Patients and Methods. We studied 526 men with organ-confined and locally advanced PCa with a median follow-up time of 7.4 years. We investigated the effects of allelic variants of SRD5A1 and SRD5A2 genes and haplotype-tagging single nucleotide polymorphisms (htSNPs; n=19) on recurrence-free survival after RP using Kaplan-Meier plots, the log-rank test, and Cox proportional hazard models. Results. Upon adjusting for known prognostic clinical and pathological factors, eight htSNPs were shown to be independent predictors of recurrence. The SRD5A1 rs166050 polymorphism was associated with an increased recurrence risk of HR=1.83 (95% CI, 1.04-3.21; P=0.035), while the rs518673 in SRD5A1 was associated with a decreased risk (HR=0.59, 95% CI, 0.41-0.

Abstract: Intensity standardization of MRI data sets aims at correcting scanner-dependent intensity variations. An automatic technique, called STI, which shares the simplicity and robustness of histogram-matching techniques, but also incorporates tissue spatial intensity information, has been discovered. The method comprises registering a medical image to a standard image; applying one or more masks to the image medical and standard images for isolating certain specific image components; determining the most common intensity data pair between the medical and standard images for each isolated image component; calculating a formula that joins the most common intensity data pair of each image component; and interpolating an intensity data adjustment using the formula and applying it to the medical image data to generate a standardized version of the medical image.
