PURPOSE We aimed to evaluate ultrasonography (US) findings for Breast Imaging Reporting and Data System (BI-RADS) category 4 lesions using BI-RADS US lexicon and determine the positive and negative predictive values (PPV and NPV) of US with respect to biopsy results. METHODS Sonograms of 186 BI-RADS 4 nonpalpable breast lesions with a known diagnosis were reviewed retrospectively. The morphol...

The internal rate of return (IRR) is generally considered inferior to the net present value (NPV) as a tool for evaluating and ranking projects, despite its inherently useful comparability to the cost of capital and the return of other investment opportunities. We introduce the ‘‘selective IRR’’, a return criterion which, as a selection of an extended set of possible IRRs, is NPV-consistent. Th...

Background/introduction Symptomatic localized adenomyosis is generally treated conservatively, or with more radical treatments such as hysterectomy. An effective non-invasive therapy is needed, especially for those who wish to preserve their fertility. MR-guided Focused Ultrasound ablation (MRgFUS) has been shown as an effective treatment for symptomatic uterine leiomyomas with a large non-perf...

Tungsten carbonyl dimers bridged with oligo(2,5-dialkoxy-1,4-phenylene vinylene)s through coordination with pyridine as the end groups, expressed as [W(CO)5]2-(nPV-Py2) [n = 1, 3; alkoxy = O(CH2)2OSi(i)Pr3], have been prepared from W(CO)5(THF) with nPV-Py2 in THF, and their structures were determined by X-ray crystallography. Both increase in absorbance and redshift in the λmax values in [W(CO)...

Accessible online at: www.karger.com/journals/res Although negative pressure ventilation (nPV) is an effective therapy for patients with restrictive lung disease [1] its position in the management of chronic ventilatory failure due to chronic obstructive pulmonary disease (COPD) is less clear. In the largest study to address this question Shapiro et al. [2] randomised 184 patients to receive ei...

In the paper a model of non-financial investment profitability calculation is presented. It based on concept quantile risk measures and real option valuation. Application Monte Carlo simulation allows to receive probability distribution Net Present Value (NPV) implement like Cash Flow at Risk (CFaR), (NPVaR) or Expected Shortfall (ES) in relation NPV (ES (NPV)). The main contribution article im...

BACKGROUND Magnetic resonance index of activity (MaRIA) and Clermont score are currently the two main MRI indices that have been validated compared to endoscopy in Crohn's disease (CD). AIMS To compare the accuracy of MaRIA and Clermont score in assessing CD mucosal healing. METHODS Fourty-four CD patients underwent prospectively and consecutively MRI and colonoscopy. RESULTS Considering ...

The gypsy moth, Lymantria dispar (L.) (Lepidoptera: Lymantriidae) nucleopolyhedrovirus LdMNPV was tested as a synergist for nucleopolyhedroviruses against Helicoverpa zea (Boddie), Spodoptera exigua (Hübner), and Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) larvae. The addition of the gypsy moth NPV significantly decreased the LC50s of AcMNPV, AfMNPV, GmMNPV, HaMNPV, HzSNPV, PxMN...
