The cell walls of these organisms are outlined by the brown to black stain. The principle of GMS is the reduction of silver ions, which renders the fungal cell wall black. The fungal cell wall commonly contains polysaccharides. In a GMS procedure, chromic acid is first used to oxidize polysaccharides, generating aldehydes. Then Grocott's ...
The Paris System for reporting urine cytology, version 2.0, ranging from negative to positive for high grade urothelial carcinoma. [1] Urine cytology is a test that looks for abnormal cells in urine under a microscope. The test commonly checks for infection, inflammatory disease of the urinary tract, cancer, or precancerous conditions.
Three types may occur in urine: squamous epithelial cells, transitional epithelial cells and renal tubular epithelial cells. Some laboratories do not distinguish between the three types of cells and simply report "epithelial cells" in general. [104] Squamous epithelial cells line the urethra, as well as the vagina and the outer layer of the skin.
Nakaseomyces glabratus is a species of haploid yeast of the genus Nakaseomyces, previously known as Candida glabrata.Despite the fact that no sexual life cycle has been documented for this species, N. glabratus strains of both mating types are commonly found. [1]
A urine test is any medical test performed on a urine specimen. The analysis of urine is a valuable diagnostic tool because its composition reflects the functioning of many body systems, particularly the kidneys and urinary system , and specimens are easy to obtain. [ 1 ]
In the budding yeast Saccharomyces cerevisiae, mating-type is determined by two non-homologous alleles at the mating-type locus. S. cerevisiae has the capability of undergoing mating-type switching, that is conversion of some haploid cells in a colony from one mating-type to the other. Mating-type switching can occur as frequently as once every ...
Y187 is a strain of yeast (Saccharomyces cerevisiae) used in biological research for two-hybrid screening.The strain has been sold commercially by Clontech [1] since at least 2000 and is used as a partner with strain AH109 in mating assays.
This mutant yeast strain can be made to incorporate foreign DNA in the form of plasmids. In yeast two-hybrid screening, separate bait and prey plasmids are simultaneously introduced into the mutant yeast strain or a mating strategy is used to get both plasmids in one host cell. [9] The second high-throughput approach is the library screening ...
