A carbohydrate fermentation technique has been developed and compared to the standard fermentation test with cystine-Trypticase-semisolid agar for the identification of Neisseria meningitidis. This new method utilizes Mueller-Hinton broth as a basal substrate and is performed with microtiter methods. By using Mueller-Hinton broth with and without the addition of antibiotics, the method can be a...

This study is focused on in vitro permeation of the original Czech compound, a skin/mucosa tissue regeneration promoter, known under the international nonproprietary name "alaptide," in micronized and nanonized forms. Alaptide showed a great potential for local applications for treatment and/or regeneration of the injured skin. The above mentioned technological modifications influence the perme...

The ability of Candida albicans to transit between different cellular morphologies is believed to be important for virulence. Morphological transitions occur in response to a variety of environmental signals. One such signal is encountered when cells are grown in a semisolid matrix. An important regulator of cellular morphology is the putative transcription factor CZF1. Here we demonstrate that...

The number of cells within tumor colonies has not been determined accurately in prior reports because, in all but small clusters, cells grow too closely and stacked to allow direct counting of cells by inverted microscopy. Therefore, we stained colonies formed in agar from 38 tumor cell samples of diverse histological origin, removed them with a micropipet, and directly counted the number of ce...

Electroand magnetorheological fluids are smart, synthetic fluids changing their viscosity from liquid to semisolid state within milliseconds if a sufficiently strong electric or magnetic field is applied. When used in suitable devices, they offer the innovative potential of very fast, adaptively controllable interfaces between mechanical devices and electronic control units. This paper gives an...

NMR spectroscopy is a commonly used technique for metabolite analyses. Due to the observed macroscopic magnetic susceptibility in biological tissues, current NMR acquisitions in measurements of biological tissues are generally performed on tissue extracts using liquid NMR or on tissues using magic-angle spinning techniques. In this study, we propose an NMR method to achieve high-resolution J-re...

2024 Aluminum alloy was squeezed cast by the Gas Induced Semi Solid (GISS) process. Effect of artificial aging on microstructure and mechanical properties of this alloy was studied in the present work. The solutionized specimens were aged hardened at temperatures of 175°C, 200°C, and 225°C under various time durations. The highest hardness of about 77.7 HRE was attained from specimen aged at th...

ABSTRACT The present study was undertaken to determine the diffusion rate of a drug from a semisolid dosage form using different membranes and to explore a membrane and to find out the comparative membrane identical to human skin with respect to diffusion rate of the drug from the selected dosage form. In the present study, Franz cell was used to carry out the diffusion study through fuzzy rat ...

Salmonellae were isolated from naturally infected swine and human feces by means of selective migration through semisolid enrichment (SM) media in modified "U" tubes. Comparative studies showed that recovery of Salmonella by SM techniques was equal or superior to that of standard procedures employed in two routine diagnostic laboratories. Primary Salmonella isolations from SM enrichment were re...

Isolation of Campylobacter jejuni and C. coli from stool specimens is done by growing campylobacter colonies on solid selective media with or without blood. However, recognition of these colonies can be difficult. Therefore, we decided to evaluate an isolation procedure based on the swarming of campylobacters through a semisolid medium. We developed a semisolid blood-free selective motility (SS...
