OBJECTIVE To determine the long-term safety of pars plana vitrectomy (PPV) in eyes with plaque-irradiated posterior uveal melanoma. METHODS In this retrospective case series, patients with plaque-irradiated posterior uveal melanoma subsequently underwent PPV for vitreous hemorrhage. The main outcome measures are the rates of intraocular melanoma dissemination, extrascleral extension of melano...

The receiver operating characteristic (ROC) curve, the positive predictive value (PPV) curve and the negative predictive value (NPV) curve are three measures of performance for a continuous diagnostic biomarker. The ROC, PPV and NPV curves are often estimated empirically to avoid assumptions about the distributional form of the biomarkers. Recently, there has been a push to incorporate group se...

In this letter, we study the memristor-based oscillators, and propose for the first time the method of calculating its PPV (Perturbation Projection Vector). In order to get PPV, we have deduced the formula to convert PRC (Phase Response Curve) to PPV. The conversion method is verified rigorously by comparing PPV obtained from PSS+PXF simulation and PRC calculated from transient simulation of tw...

Over an approximately 80-year period since the description of the Sharka disease, the plum pox virus (PPV) has been thoroughly studied on various levels of the infection cycle. World-wide distribution of the virus, severity of the disease for the fruit industry with a potential to be further increased and discovery/emergence of new strains make PPV the most epidemiologically important viral pat...

KAMENOVA, I., 2016. Non-transmission of plum pox virus through seeds of myrobalan and apricot. Bulg. J. Agric. Sci., 22: 267–271 Seeds from wild-grown myrobalan (Prunus cerasifera Ehrh.) infected with PPV-D strain and from apricot (P. armeniaca) infected with PPV-Rec strain were investigated for their potential role in virus transmission. The presence of PPV was checked in fully ripe seeds, gem...

With the aim to develop an efficient and cost-effective approach to control malaria, we have generated porcine parvovirus-like particles (PPV-VLPs) carrying the CD8(+) T cell epitope (SYVPSAEQI) of the circumsporozoite (CS) protein from Plasmodium yoelii fused to the PPV VP2 capsid protein (PPV-PYCS), and tested in prime/boost protocols with poxvirus vectors for efficacy in a rodent malaria mod...
