A Randomized Trial of Ionic Silver Dressing to Reduce Surgical Site Infection After Gastrointestinal Surgery.

Objective: To determine whether Aquacel Ag Hydrofiber dressings containing ionic silver are superior to film dressings for preventing superficial surgical site infections (SSI) in patients undergoing elective gastrointestinal surgery.

Background: Multiple clinical trials have assessed the effectiveness of silver-containing wound dressings; however, systematic reviews failed to find any advantages of these dressings and concluded that there was insufficient evidence to indicate that they prevented wound infections. This study aimed to evaluate the efficacy of Aquacel Ag Hydrofiber dressings for preventing superficial SSIs in patients undergoing gastrointestinal surgery.

[A Case of the Huge GIST in the Transverse Colon Mesentery with Intra-Tumoral Hemorrhage and Jejunal Infiltration].

A 38-year-old woman was admitted to our hospital due to severe anemia. CT showed a 13×12 cm tumor with moderately enhanced wall thickening in the right upper abdomen. The huge tumor located adjacent to the jejunum and compressed the right transverse colon.

Optically powered radio-over-fiber system based on center- and offset-launching techniques using a conventional multimode fiber.

We demonstrate radio-over-fiber (RoF) transmission with a 10-W feed power-over-fiber (PWoF) using a conventional multimode fiber (MMF). In this scheme, the modal dispersion and feed light crosstalk in the MMF are effectively mitigated by the combination of center-launching (CL) and offset-launching (OL) techniques. The CL is used for propagating the feed light into lower-order modes in the MMF, while the OL is used not only for propagating the optical data signals into higher-order modes in the MMF, but also for mitigating the modal dispersion.

Gamow-Teller strength distributions in 48Sc by the 48Ca(p,n) and 48Ti(n,p) reactions and two-neutrino double-beta decay nuclear matrix elements.

The double-differential cross sections for the 48Ca(p,n) and 48Ti(n,p) reactions were measured at 300 MeV. A multipole decomposition technique was applied to the spectra to extract the Gamow-Teller (GT) components. The integrated GT strengths up to an excitation energy of 30 MeV in 48Sc are 15.

Effects of a casein hydrolysate prepared from Aspergillus oryzae protease on adjuvant arthritis in rats.

We evaluated the effects of a casein hydrolysate (CH) prepared from Aspergillus oryzae protease on rat adjuvant arthritis, a model of human rheumatoid arthritis. CH was administered orally once a day to the animals for 22 d after the adjuvant injection. CH suppressed swelling in the adjuvant-uninjected hind paws, and a higher dose of CH suppressed the increase in arthritic score and swelling of the adjuvant-injected hind paws.
