The 4Kscore combines total, free and intact PSA together with human kallikrein 2. [46] It is used to try to determine the risk of a Gleason score greater than 6. [46] The Prostate Health Index (PHI) is a PSA-based blood test for early prostate cancer screening. It may be used to determine when a biopsy is needed.
They may also include density functional theory (DFT), molecular mechanics or semi-empirical quantum chemistry methods. The programs include both open source and commercial software. Most of them are large, often containing several separate programs, and have been developed over many years.
Particle size analysis, particle size measurement, or simply particle sizing, is the collective name of the technical procedures, or laboratory techniques which determines the size range, and/or the average, or mean size of the particles in a powder or liquid sample.
[10] However, problematic aspects of the original Gleason grading system still characterize the 2005 revision. The predominant lowest score assigned is Gleason 3+3 = 6. Patients who are told their Gleason score is 6 out of 10 may interpret that they have a more aggressive intermediate cancer and experience greater anxiety. [11]
Prostate-specific antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3), P-30 antigen, is a glycoprotein enzyme encoded in humans by the KLK3 gene.PSA is a member of the kallikrein-related peptidase family and is secreted by the epithelial cells of the prostate gland in men and the paraurethral glands in women.
A medical calculator is a type of medical computer software, whose purpose is to allow easy calculation of various scores and indices, presenting the user with a friendly interface that hides the complexity of the formulas.
The development of ORCA started in 1997, while Frank Neese was on his PostDoc at Stanford University.Since then the ORCA development went on, following Neese to his stations at the University of Bonn, the Max-Planck-Institute for Chemical Energy Conversion, and finally the Max-Planck-Institut für Kohlenforschung.
PC3 (PC-3) is a human prostate cancer cell line used in prostate cancer research and drug development. [1] PC3 cells are useful in investigating biochemical changes in advanced prostate cancer cells and in assessing their response to chemotherapeutic agents. PC3 cells are also used to study viral infection in mammalian cells that exhibit an ...
