Abstract: A transobturator technique was developed for treating male urinary incontinence. This approach helped to design specific instruments to pass around the ischio-pubic branches of the male pelvis from inside to outside (i.e from the suburethral space to the thigh fold). The inside-out transobturator sling technique uses specific instruments and a polypropylene mesh with two arms that are passed inside to outside through the obturator foramens, pulled for compressing the bulbar urethra upward, and tied to each other across the midline. The mesh passes around the ischio-pubic branch before being tied under the bulbar urethra where it brings tension and support.

Abstract: A method can be used for treating or reducing likelihood of an influenza A virus-induced disease in a mammal. The method includes administering a polynucleotide to the mammal. Theis polynucleotide includes a gene encoding Mx protein having a TRAF2 and/or a TRAF6 binding domain. The TRAF2 and/or TRAF6 binding domain can be represented by the sequences P-X-Q/E-E, P-X-Q/E-X-X-D, or P-X-E-E-X-E. The TRAF2 and/or TRAF6 binding domain can also be located in the Mx protein in a position which corresponds to the position of the hexapeptide PEEESE in the bovine Mx1 protein or in a position which is up to 20 amino acid residues upstream or downstream of that position.

Abstract: The present invention provides MT4-MMP inhibitor and EGFR inhibitor for use in the treatment of cancer, wherein said MT4-MMP inhibitor and EGFR inhibitor are different from each other. MT4-MMP (MMP-17) is a glycosylphosphatidyl inositol (GPI) anchored MMP produced by cancer cells that promotes tumor vascularization and metastases. The present invention found that MT4-MMP expression promotes cancer cell proliferation. These effects involve retinoblastoma protein (Rb) inactivation, cyclin dependent kinase CDK4 activation and Epidermal Growth Factor Receptor (EGFR) signaling. Co-immuno-precipitations indicate the existence of protein complexes harboring MT4-MMP and EGFR. The present invention further found a novel mechanism of MT4-MMP action through an outside-in signaling involving EGFR. An unexpected crosstalk between an MMP and EGFR was identified and recognized as a key driver of cancer cell biology.

Abstract: Disclosed is a system and device for observation of an eye (E) comprising a light source (LSo) for illuminating the eye. Further, the system includes a diffraction grating as an optical relay (OR) for receiving the light reflected from the eye and for deflecting it towards a light sensor (LSe). The incident light ray (r inc) intersects the optical relay at an incidence angle (alphajnc) with the normal (n_OR) to the optical relay in an incidence plane (Pl_inc) formed by the incident light ray (r_inc) and the normal (n_OR). The deflected light ray (r def) forms a deflection angle (alpha def) with the normal (n_OR) in a deflection plane (Pl def) formed by the deflected light ray (r_def) and the normal (n_OR). The optical relay is positioned such that the incidence and the deflection angle and/or the incidence plane and the deflection plane are different from each other.
