BACKGROUND Early detection of prostate cancer (PCa) centers on measurements of prostate-specific antigen (PSA), but current testing practices suffer from lack of specificity and generate many unnecessary prostate biopsies. Soluble urokinase plasminogen activator receptor (uPAR) is present in blood in both intact and cleaved forms. Increased uPAR in blood is correlated with poor prognosis in var...

Treatment of non-metastatic castration-resistant prostate cancer is a radically new option for patients. Novel anti-hormonal therapy not only improves metastasis free survival but overall times and positively impacts quality life. This case shows how apalutamide lowered tPSA level postponed metastatic disease.

there are emerging data on novel tumor markers such as matrix metalloproteinase-2 (mmp-2 or gelatinase-a), which play a key role in tissue invasion and metastasis. we designed an investigation to assess the usefulness of mmp-2 activity as compared to prostate specific antigen (psa) in cancer staging process. we have analyzed the circulating form of mmp-2 in serum samples of patients suffering f...

We test two-dimensional TPSA of biphoton light emitted via ultrafast spontaneous parametric down-conversion (SPDC) using the effect of group-velocity dispersion in optical fibres. Further, we apply this technique to demonstrate the engineering of biphoton spectral properties by acting on the pump pulse shape.

The first example of an activated phosphonated trifunctional chelate (TFC) is presented, which combines a non-macrocyclic coordination site for lanthanide coordination based on two aminobis-methylphosphonate coordinating arms, a central bispyrazolylpyridyl antenna and an N-hydroxysuccinimide ester in para position of the central pyridine as an activated function for the labeling of biomaterial....

Prostate-specific antigen (PSA) is the most useful marker in the early detection of prostate cancer and for the monitoring of patients with this diagnosis. Molecular forms of PSA and also human kallikrein 2 have been used to discriminate between benign prostatic hyperplasia and prostate cancer as well as for the detection of prostate cancer within the gray zone of PSA. In this respect, a litera...

Molecular polar surface area (PSA), i.e., surface belonging to polar atoms, is a descriptor that was shown to correlate well with passive molecular transport through membranes and, therefore, allows prediction of transport properties of drugs. The calculation of PSA, however, is rather time-consuming because of the necessity to generate a reasonable 3D molecular geometry and the calculation of ...
