OBJECTIVE The aim of this study was to compare responses to single-agent chemotherapies and evaluate the predictive factors of resistance in low risk (LR) gestational trophoblastic disease (GTD). The chemotherapy agents included methotrexate (MTX) and actinomycin D (ACT-D). METHODS We conducted a retrospective study of 126 patients with GTD who were treated between 2000 and 2013. A total of 7...

Microcystins produced from cyanobacteria can accumulate in fish tissues. Liquid chromatography coupled with tandem quadrupole mass spectrometry (LC-MS/MS) is an attractive alternative to immunoassays for the determination of low concentrations of microcystins in tissues. Fish taken from Grand Lake St. Marys, a eutrophic lake in Ohio, USA, were analyzed for microcystin-LR in their fillets using ...

rock chutes are natural river training structures and are efficient energy dissipaters too. from the hydraulic and environmental point of view, rock chutes have become important structures in the natural river morphology. a physical study was conducted and flow properties were measured over rough bed materials of a rock chute, which was assembled at the pitlab center of the university of pisa, ...

During the early postnatal age environmental signals underlie development of sensory systems. The visual system is considered as an appropriate system for evaluation of the role of sensory experience in postnatal development of sensory systems. In this study we evaluated the effect of visual deprivation on the usage of visuospatial cues in navigation of radial arm maze. Light (LR) and dark rear...

Super-resolution (SR) is a technique that produces a high resolution (HR) image via employing a number of low resolution (LR) images from the same scene. One of the degradations that attenuates performance of the SR is the blurriness of the input LR images. In many previous works in the SR, the blurriness of the LR images is assumed to be due to the integral effect of the image sensor of the im...

Left-to-right (LR) decoding (Watanabe et al., 2006b) is a promising decoding algorithm for hierarchical phrase-based translation (Hiero). It generates the target sentence by extending the hypotheses only on the right edge. LR decoding has complexity O(nb) for input of n words and beam size b, compared toO(n) for the CKY algorithm. It requires a single language model (LM) history for each target...

The Pearson’s chi-squared statistic (X2) does not in general follow a chi-square distribution when it is used for goodness-of-fit testing for a multinomial distribution based on sparse contingency table data. We explore properties of Zelterman’s (1987) D2 statistic and compare them with those of X2 and we also compare these two statistics and the statistic (Lr) which is proposed by Maydeu-Oliva...
