Digital subtraction angiography (DSA) permits high-resolution cardiac imaging with relatively low doses of contrast medium and reduced radiation exposure. These are potential advantages in children with congenital heart disease. Computer-based DSA (30 frames/sec) and conventional cutfilm angiography (6 frames/sec) or cineangiography (60 frames/sec) were compared in 42 patients, ages 2 months to...

Abstract Study question Our aim is presenting a clinical case of pregnancy using intracytoplasmatic sperm injection with bacterial contamination embryo culture after failed conventional in vitro fertilisation. Summary answer Intracytoplasmatic (ICSI) can be an effective and safe method to prevent infection microbial semen. What known already Contamination rare, but detrimental. The most common ...

Objective: Cholera is an acute secretory diarrhea caused by the Gram-negative bacterium, Vibrio cholerae mostly through production of cholera toxin (CT) and zonula occludens toxin (Zot).<span style="fon...

A comparison of rifampin susceptibility test results on 407 strains of mycobacteria using conventional medium in parallel with disk medium showed good agreement. Techniques are described for utilization of drug-impregnated disks in the preparation of medium and for a quality control screening procedure for disks.

During a 6-month period, 5,375 clinical specimens were cultured on Middlebrook-Cohn 7H10 medium, on Lowenstein-Jensen medium, and in Middlebrook 7H12 medium containing [14C]palmitic acid. More mycobacteria were recovered when all three media were used than when either the conventional method with 7H10 agar and Lowenstein-Jensen slants or the radiometric method with 7H12 broth was used alone.

BACKGROUND & OBJECTIVES A cyclic lipopeptide (CLP), surfactin produced by a strain of Bacillus subtilis subsp. subtilis (VCRC B471) was found to exhibit mosquitocidal activity. The present study was carried out to enhance the surfactin level using low cost material in the production medium. METHODS Two carbon sources, glucose and common sugar, and two nitrogen sources, ammonium nitrate and so...

The conventional Lorenz-Mie formalism is extended to the case for a coated sphere embedded in an absorbing medium. The apparent and inherent scattering cross sections of a particle, derived from the far field and near field, respectively, are different if the host medium is absorptive. The effect of absorption within the host medium on the phase-matrix elements associated with polarization depe...

Using the medium of ZoBell as a basal formulation, we developed a medium to determine the oxidative-fermentative metabolism in marine bacteria. Different oxidative and fermentative collection strains, as well as a group of unidentified marine bacteria, were tested on modified ZoBell medium and other conventional media. In general, superior results were obtained with the modified ZoBell medium s...
