OBJECTIVE The aim of this study was to prove, whether the intracutaneous skin closure with self made fishing line suture is equivalent to commercial sutures. DESIGN It was a randomised blinded animal study. SETTING The study was performed in December 2002 at the Muhimbili University College of Health Sciences in Dar-es-salaam. SUBJECTS Both German surgeons from Mannheim, and Tanzanian sur...

A new apparatus, named Bang-Bang (BB), which can facilitate the in situ nylon bag measurement of ruminal degradation in beef cattle, is described. The BB is an apparatus specially designed as a replacement of the traditional steel chain or flexible plastic tubes for binding the bags used in the in situ nylon bag (ISNB) method. The BB apparatus consists of cylindrical pedestals, sealing clips, n...

Studies were undertaken to determine whether BSA, once immobilized on activated nylon microspheres, would be capable of specifically removing circulating BSA antibody in vitro and in vivo in an extracorporeal circulation system in dogs. Nylon microspheres were prepared and, after gentle hydrolysis and glutaraldehyde treatment, demonstrated a retention of up to 34.5 mg of BSA. In vitro studies s...

Inorganic fullerene-like WS2 nanoparticle- (IF-WS2) reinforced nylon 12 nanocomposites have been prepared through effective ultrasonic mixing without using any surfactant, followed by molding at 220 °C. Morphological characterizations using scanning electron microscopy (SEM), transmission electron microscopy (TEM) and microcomputed tomography (micro-CT) have revealed the excellent dispersion of...

Separators are needed in microbial fuel cells (MFCs) to reduce electrode spacing and preventing electrode short circuiting. The use of nylon and glass fiber filter separators in single-chamber, aircathode MFCs was examined for their effect on performance. Larger pore nylon mesh were used that had regular mesh weaves with pores ranging from 10 to 160 mm, while smaller pore-size nylon filters (0....

INTRODUCTION Nylon-Darn herniorrhaphy is a classic, open technique, simple to perform with a low recurrence rate. It is a "tension-free" method of herniorrhaphy. The aim of study was to analyze the results of Nylon-Darn herniorrhaphy at our clinic and point out advantages and disadvantages of the technique. MATERIAL AND METHODS This study, dating back to May 1999 and up to May 2005, included ...

Adherence of chicken heterophils was evaluated at 37 C using preconstructed columns containing various weights of nylon fiber (75 mg, 100 mg, or 125 mg) and whole blood anticoagulated with sodium heparin or 10% disodium ethylenediamine tetraacetic acid (EDTA). Additionally, 50-mg and 75-mg nylon fiber columns incubated at 41 C were used to evaluate heterophil adherence at an increased temperatu...

We describe a continuous-flow bioluminescence method for measuring primary bile acid in serum, with nylon as the solid support. 7 alpha-Hydroxysteroid dehydrogenase (EC 1.1.1. 159), a bacterial luciferase (EC 1.14.14.3), and NAD+:FMN oxido-reductase (EC 1.6.8.1) are covalently co-immobilized on a nylon coil (1 m X 1.0 mm i.d.). The assay is highly specific for 7 alpha-hydroxy bile acids. Other ...

PURPOSE This in vitro study intended to investigate the mechanical and thermal characteristics of Valplast, and of polymethyl methacrylate denture base resin in which different esthetic fibers (E-glass, nylon 6 or nylon 6.6) were added. MATERIALS AND METHODS FIVE GROUPS WERE FORMED: control (PMMA), PMMA-E glass, PMMA-nylon 6, PMMA-nylon 6.6 and Valplast resin. For the transverse strength test...

The Brown Foundation, chaired by George R. Brown, provided f u n d s fo r t e a c h i n g a w a r d s beginning in 1967. This year the awards were determined by the votes of alumni with Bachelor's degrees who graduated in I980and vote in preferential order for the three faculty who they remember as outstanding teachers. The Nicolas Salgo Distinguished Teacher Award is funded by The Noren Salgo ...
