Out of the 30 actinobacterial cultures screened for antimicrobial activity, 28 cultures were found to produce active products against various pathogenic microorganisms such as Gram-negative, Gram-positive bacteria and yeast, using a modified cross streak method. The modified method helped in easy quantification of results and also in ruling out probable mutual antibiosis. The actinobacterial st...

The general principle underlying the method described below is that of deviation electrophoresis. The mixture of ions to be spearated from each other enters an electric field in form of a thin streak carried by a buffer flow transversely to the electric field. The streak is affected by the electric field similarly to a zone in zone electrophoresis. The different ions are moved by the electric f...

In mammals, the primitive streak region and its descendant, the tail bud, are the source of nascent mesoderm and spinal cord throughout axial elongation. A localised population of long-term axial progenitors has been identified in a region of the tail bud, the chordoneural hinge, but the localisation of such progenitors at earlier stages is so far untested. By studying gene expression, we have ...

Twenty five clinical isolates of high level gentamicin resistant Enterococcus faecalis were tested for their biofilm formation and pheromone responsiveness. The biofilm assay was carried out using microtiter plate method. Two isolates out of the 25 (8%) were high biofilm formers and 19 (76%) and four (16%) isolates were moderate and weak biofilm formers respectively. All the isolates responded ...

The objective of this study was to explore the utility of nitrile gloves as a replacement for latex surgical gloves in recovering bacteria from the hands. Two types of nitrile gloves were compared to latex gloves using the parallel streak method. Streaks of Klebsiella pneumoniae and Staphylococcus aureus were made on tryptic soy agar plates, and the zones of inhibition were measured around piec...

An interferometric method that was used to measure the electro-optic s(11) coefficient of nitrobenzene is presented. The method uses a Mach-Zehnder interferometer arrangement that produces a finite fringe interferogram. A nitrobenzene Kerr cell is placed in one arm of the interferometer and a pulsed high voltage is applied to the two rectangular electrodes. The voltage application causes the fr...

We introduce a novel method for the generation of fully adaptive streak surfaces in time-varying flow fields based on particle advection and adaptive mesh refinement. Moving least squares approximation plays an important role in multiple stages of the proposed algorithm, which adaptively refines the surface based on curvature approximation and circumradius properties of the underlying Delaunay ...

abstract objective: to investigate the effect of an anti-inflammatory drug (piroxicam) on the development of fatty streak in rabbits. methods: male rabbits were fed with four types of regimen: a) normal rabbit chow, b) 1% cholesterol diet c) cholesterol diet plus piroxicam, d) normal rabbit chow plus piroxicam. after 12 weeks, the animals were sacrificed and the aorta, as well as the right and ...

Cell soma area or diameter distributions are generally very skewed and present some unusual problems in characterization and description. In this study of ganglion cell soma size in rabbit retina, our conclusions are based on a statistical method which not only characterizes this particular neuronal population but which also may be of considerable value in other species and other parts of the n...
