although candida albicans is the most common etiologic agent of candidiasis, c. dubliniensis, has been emerged, as another pathogen resembles c. albicans in many phenotypic aspects and noted for its in vitro potential for fluconazole resistance. since there was no evidence of any report about detection of this organism in iran, this study was designed to use of five different tests for identifi...

We applied the Luria and Delbruck fluctuation test to analyze high-frequency changes in the phenotype of rat cells transformed by a plasmid carrying the polyomavirus middle T (pmt) gene. All of the transformed cell lines analyzed were capable of switching to the normal state with rates ranging from 10(-3) to 10(-2) per cell per generation. Analysis of both middle T antigen and middle T transcri...

Reference isolates of Candida parapsilosis (n = 8), Candida metapsilosis (n = 6), Candida orthopsilosis (n = 7), and Lodderomyces elongisporus (n = 11) were analyzed to gain insight into their pathobiology and virulence mechanisms. Initial evaluation using BBL Chromagar Candida medium misidentified L. elongisporus isolates as C. albicans. Polymerase chain reaction analysis of isolate MTL idiomo...

Malignant glioma is characterized by rapid proliferation, invasion into surrounding central nervous system tissues, and aberrant vascularization. There is increasing evidence that shows gliomas are more complex than previously thought, as each tumor comprises considerable intratumoral heterogeneity with mixtures of genetically and phenotypically distinct subclones. Heterogeneity within and acro...

rhizosphere soil samples were collected from olive orchards of golestan, guilan, zanjan and qom provinces. fluorescent pseudomonad strains were isolated from the collected samples on king’s b medium and their phenotypic features characterized as based on the standard bacteriological methods. for all the tested strains oxidase reaction, fluorescent pigment, growth at 4?c and arginine dihydrolase...

Bacillus cyclic lipopeptides (LPs) have been well studied for their phytopathogen-antagonistic activities. Recently, research has shown that these LPs also contribute to the phenotypic features of Bacillus strains, such as hemolytic activity, swarming motility, biofilm formation, and colony morphology. Bacillus subtilis 916 not only coproduces the three families of well-known LPs, i.e., surfact...

I. Aetna considers TPMT gene mutation or TPMT phenotypic assays (e.g., Prometheus TPMT Genetics, Prometheus TPMT Enzyme) medically necessary prior to initiation of 6mercaptopurine or azathioprine therapy. Only 1 genotypic or phenotypic assay of TPMT activity is necessary per member per lifetime. TPMT gene mutation assays and TPMT phenotypic assays are considered experimental and investigational...

26 27 28 Aims: The use of RAPD-PCR fingerprinting and plasmid profiles to determine at the 29 strain level, the similarity of Lactococcus lactis isolates obtained during sampling of 30 traditional cheeses and to verify its correspondence to the selected phenotypic 31 characteristics. 32 Methods and Results: A total of 45 L. lactis isolates were genotypically analyzed by 33 RAPD-PCR fingerprinti...

3D tissue cultures provide a more physiologically relevant context for the screening of compounds, compared with 2D cell cultures. Cells cultured in 3D hydrogels also show complex phenotypes, increasing the scope for phenotypic profiling. Here we describe a high-content screening platform that uses invasive human prostate cancer cells cultured in 3D in standard 384-well assay plates to study th...

The phosphodiesterase inhibitor tetrahydrophthalazinone NPD-008 was explored by phenotypic in vitro screening, target validation, and ultrastructural approaches against Trypanosoma cruzi . displayed activity different forms strains of T. (50% effective concentration [EC 50 ], 6.6 to 39.5 μM). Increased cAMP levels its combination with benznidazole gave synergistic interaction.
