S. cerevisiae has developed as a model organism because it scores favorably on a number of criteria. As a single-cell organism, S. cerevisiae is small with a short generation time (doubling time 1.25–2 hours [40] at 30 °C or 86 °F) and can be easily cultured. These are all positive characteristics in that they allow for the swift production ...
S. cerevisiae cells imaged by DIC microscopy A quantitative phase-contrast microscopy image of cells in culture. The height and color of an image point correspond to the optical thickness, which only depends on the object's thickness and the relative refractive index. The volume of an object can thus be determined when the difference in ...
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.
Examples of urinary casts: a) RTE cell cast, b) "muddy" granular cast, c) white blood cell cast, d) red blood cell cast [112] Urinary casts are cylindrical structures composed of Tamm-Horsfall glycoprotein. Their shape derives from the renal tubules where they are formed, and the protein base can incorporate cells or other material. Hyaline ...
The first hint that led to the discovery of the SCF complex came from genetic screens of Saccharomyces cerevisiae, also known as budding yeast.Temperature-sensitive cell division cycle (Cdc) mutants—such as Cdc4, Cdc34, and Cdc53 [6] —arrested in G1 with unreplicated DNA and multiple elongated buds.

Sic1, a protein, is a stoichiometric inhibitor [1] of Cdk1-Clb (B-type cyclins) complexes in the budding yeast Saccharomyces cerevisiae.Because B-type cyclin-Cdk1 complexes are the drivers of S-phase initiation, Sic1 prevents premature S-phase entry. [2]
Anti-Saccharomyces cerevisiae antibodies (ASCAs) are antibodies against antigens presented by the cell wall of the yeast Saccharomyces cerevisiae.These antibodies are directed against oligomannose sequences α-1,3 Man (α-1,2 Man α-1,2 Man) n (n = 1 or 2). [1]
Berkeley bodies are organelles unique to the yeast cell Saccharomyces cerevisiae, with a secretory mutation in the genes sec7 and sec14.The function of the organelle lies in the CTV (cytoplasm to vacuole targeting) pathway, which is a transport pathway for certain vacuolar hydrolases to be degenerated.
