The lattice of 5,7,12,14-tetrahydro-5,14:7,12-bis([1,2]benzeno)pentacene-6,13dione, C34H20O2, at 173 K has triclinic (P1) symmetry and crystallizes with four independent half-molecules in the asymmetric unit. Each molecule is generated from a C17H10O substructure through an inversion center at the centroid of the central quinone ring, generating a wide H-shaped molecule, with a dihedral angle b...

healthy 58-year-old woman had undergone arthrosopy of both temporomandibular joints because of ilateral mandibular clicks and recurrent episodes of aw block that did not respond to nonsurgical treatent. The preoperative examination showed general estriction of mandibular motility (maximal oral aperure 26 mm, right and left lateral deviation 11 and 8 m, respectively, protrusion 10 mm, and dental...

The failed back surgery syndrome (FBSS) is a difficult diagnostic problem both clinically and radiologically. Forty-three patients were evaluated prospectively with magnetic resonance imaging (MRI) and forty-five scans were obtained. Fifteen patients (33%) showed recurrent disc prolapse; 15 (33%) patients postoperative epidural fibrosis; 8 (18%) both recurrent disc prolapse and epidural scarrin...

conclusions this study showed that multiple β-lactamases can be produced in burn isolates. this suggests that use of cephalosporins and carbapenems should be restricted in burn isolates to minimize the development and spread of these multidrug resistant pathogens. results there was 99% resistance to carbenicillin, and ticarcillin, 98% to cotrimoxazole, 96% to ciprofloxacin, and aztreonam, 95% t...

Interferon (IFN) mediates its antiviral effects by inducing a number of responsive genes, including the double-stranded RNA (dsRNA)-dependent protein kinase, PKR. Here we report that inducible overexpression of functional PKR in murine fibroblasts sensitized cells to apoptosis induced by influenza virus, while in contrast, cells expressing a dominant-negative variant of PKR were completely resi...

Cracked and un-cracked Brazilian disc specimens subjected to diametral compression were used for conducting fracture toughness and tensile strength experiments on a polymer concrete (PC) material. The value of mode I fracture toughness (KIc) was determined from the center- cracked Brazilian disc and the indirect tensile strength (σt) was obtained from the un-cracked Brazilian disc specimen. The...

OBJECTIVE Pfirrmann disc degeneration grade is one of morphologic disc degeneration grading system and it was reliable on routine T2-weighted magnetic resonance (MR) images. The purpose of this study was to evaluate the agreement of Pfirrmann disc degeneration grade, and check the alternative technique of disc degeneration grading system. METHODS Fifteen volunteers (4 medical doctors related ...

The reverse genetics technology for bluetongue virus (BTV) has been used in combination with complementing cell lines to recover defective BTV-1 mutants. To generate a potential disabled infectious single cycle (DISC) vaccine strain, we used a reverse genetics system to rescue defective virus strains with large deletions in an essential BTV gene that encodes the VP6 protein (segment S9) of the ...
