To analyse the performance of Prostate Cancer Prevention Trial Risk Calculator (PCPT-RC) and two iterations European Randomised Study Screening for (ERSPC) Calculator, one which incorporates prostate volume (ERSPC-RC) other health index (PHI) in a referral population (ERSPC-PHI).The risk cancer (PCa) significant PCa (Gleason score ≥7) 2001 patients from six tertiary centres was calculated according to PCPT-RC ERSPC-RC formulae. The calculators' predictions were analysed using area under...

We construct a family of trees with independence numbers going to infinity for which the log-concavity relation independent set sequence tree $T$ in fails at around $\alpha(T)\left(1-1/(16\log \alpha(T))\right)$. Here $\alpha(T)$ is number $T$. This resolves conjecture Kadrawi and Levit.

It is shown that the hard-core model on ${{\mathbb Z}}^d$ exhibits a phase transition at activities above some function $\lambda(d)$ which tends to zero as $d\rightarrow \infty$. More precisely, consider usual nearest neighbour graph Z}}^d$, and write ${\cal E}$ O}$ for sets of even odd vertices (defined in obvious way). Set $${\cal G}L_M={\cal G}L_M^d =\{z\in{{\mathbb Z}}^d:\|z\|_{\infty}\leq M\},\quad \partial^{\star} {\cal G}L_M Z}}^d:\|z\|_{\infty}= M\},$$ I}({\cal G}L_M)$ collection...

Introduction: Fracture of the penis is a rare urological emergency which occurs as result abrupt trauma to an erect penis. There paucity data regarding long-term sexual function or erectile potency following fracture The aim this study objectively assess overall penis.Methods: A retrospective analysis 21 penile fractures was performed. voluntary telephone questionnaire performed long term outcomes using three validated questionnaires-the Erection Hardness Grading Scale, International Index...

Phytoestrogens are nonsteroidal plant derived compounds with estrogenic activity that have been implicated in protecting against prostate cancer progression. We hypothesized these would alter cell number and increase the ability of antiandrogens to induce death cells.RWPE-1, LNCaP PC-3 cells were treated or without an extract Belamcanda chinensis, 2 purified phytoestrogens from this (irigenin tectorigenin) antiandrogen bicalutamide. assessed effect on number, proliferation...

Abstract Galvin showed that for all fixed δ and sufficiently large n , the ‐vertex graph with minimum degree admits most independent sets is complete bipartite . He conjectured except perhaps some small values of t same yields maximum count size each possible Evidence this conjecture was recently provided by Alexander, Cutler, Mink, who triples no more than Here, we make further progress. We show obtain conclusion Our proofs lead us naturally to study an interesting family critical graphs,...
