Prostate cancer multiparametric magnetic resonance imaging visibility is a tumor-intrinsic phenomena.

Multiparametric magnetic resonance imaging (mpMRI) is an emerging standard for diagnosing and prognosing prostate cancer, but ~ 20% of clinically significant tumors are invisible to mpMRI, as defined by the Prostate Imaging Reporting and Data System version 2 (PI-RADSv2) score of one or two. To understand the biological underpinnings of tumor visibility on mpMRI, we examined the proteomes of forty clinically significant tumors (i.e.

Effect of stepped spillways on increasing dissolved oxygen in water, an experimental study.

In this study, different physical models of stepped spillways are constructed and the effect of intense water mixing on increasing the dissolved oxygen concentration in water is investigated. The minimum oxygen transfer efficiency ranged from 28% to 56%, which indicates the positive effects of stepped spillways. The results showed that with a stepped spillway, the oxygen transfer efficiency decreases with increasing discharge.
