PURPOSE Fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC) are used to determine human epidermal growth factor receptor-2 (HER-2) status and patient eligibility for trastuzumab therapy. Using FISH and IHC, we analyzed the relationship between pathologic complete response to trastuzumab-based neoadjuvant therapy and level of HER-2 amplification in locally advanced breast ca...

The aim of the present study was to identify potential human epidermal growth factor receptor 2 (HER2) amplification, according to American Society of Clinical Oncology and the College of American Pathologists (ASCO/CAP) 2013 HER2 testing guidelines, in patients previously determined not to possess HER2 amplification, in accordance with previous 2007 guidelines. Potential discrepancies may aris...

A critical question concerning generative networks applied to event generation in particle physics is if the generated events add statistical precision beyond training sample. We show for a simple example with increasing dimensionality how indeed amplify statistics. quantify their impact through an amplification factor or equivalent numbers of sampled events.

Centrosome amplification is frequent in cancer, but the underlying mechanisms remain unclear. Here we report that disruption of the Kruppel-like factor 14 (KLF14) gene in mice causes centrosome amplification, aneuploidy and spontaneous tumorigenesis. Molecularly, KLF14 functions as a transcriptional repressor of Plk4, a polo-like kinase whose overexpression induces centrosome overduplication. T...

In this work we shall calculate in detail the effect of an GW170817-compatible Einstein-Gauss-Bonnet theory on energy spectrum primordial gravitational waves. The is affected by two characteristics, overall amplification/damping factor caused and tensor spectral index tensor-to-scalar ratio. We present formalism for studying inflationary dynamics post-inflationary theories all redshifts startin...

Cultured cell lines and xenografts derived from 7 human medulloblastomas were evaluated for amplification of the c-myc, N-m>'c, epidermal growth factor receptor, and gli genes by Southern blot analysis. Karyotypes of the original biopsies and early passaged cells demonstrated double minute chromosomes in 4 of the 7 cases. All 7 samples (3 cell lines and 4 xenografts) from the 4 tumors with doub...

A critical problem in the emerging high-throughput genotyping protocols is to minimize the number of polymerase chain reaction (PCR) primers required to amplify the single nucleotide polymorphism loci of interest. In this paper we study PCR primer set selection with amplification length and uniqueness constraints from both theoretical and practical perspectives. We give a greedy algorithm that ...

The prognostic heterogeneity of multiple myeloma (MM) is largely due to different genetic abnormalities. Cytogenetic analysis has revealed that most of MM harbor chromosome aberrations. Amplification of 1q21 is one of the most common chromosomal aberrations. Interphase fluorescence in situ hybridization was applied to detect the 1q21 amplification in 86 Chinese patients with newly diagnosed MM....

Fifty-five isolates of Escherichia coli from septicaemic neonatal foals were used to validate five real-time pcr assays targeting different known virulence factor genes: curli fibre (csgD), ferric hydroxamate uptake (fhuA), type 1A pilin (fimA), aerobactin (lutA) and yersiniabactin (fyuA). A pcr assay targeting a universal sequence of the bacterial 16S rrna gene served as quality control. The p...
