PO-324 Detection of high-risk prostate cancer biomarkers by RNA sequencing and qPCR method

Introduction New prognostic biomarkers for prostate cancer have the potential to overcome the clinical challenge of therapy decision and overtreatment. Present diagnostic and prognostic tests are still limited in specificity resulting in a large number of false positives and unnecessary biopsies. Furthermore, they do not enable a proper stratification between men with a high risk for an aggressive disease course requiring comprehensive therapy scheme after surgery and men with a low risk of disease recurrence cured after prostatectomy or eligible for active surveillance. In particular, patients with Gleason score 6 and 7 tumours (low and mid stage) are difficult to stratify for the appropri…

Generalized inverse of the compliance tensor, and behaviour of incompressible anisotropic materials - Application to damage

Before the final rupture, most structural materials exhibit an import damage in the form of microvoids. The overall behaviour of a damaged elastic material depends on the void volume fraction f. Undamaged polymers are generally considered as incompressible elastic. Metals at high temperature may be considered as linearly viscoplastic. Thus the undamaged material may be described by an incompressible behaviour, while the overall behaviour of the damaged material is compressible depending on the void volume fraction. The transition from a compressible to an incompressible behaviour leads to a singular compliance matrix and an undefined rigidity matrix. The generalized inverse of the complianc…
