  1. Adaptive molecular evolution

    Yang, ZIHENG
    This chapter reviews statistical methods for detecting adaptive molecular evolution by comparingsynonymous and nonsynonymous substitution rates in protein-coding DNA sequences. A Markovprocess model of codon substitution, which forms the basis for all later discussions in this chapter,is introduced first. The case of comparing two sequences to estimate the numbers of synonymous(dS ) and nonsynonymous (dN) substitutions per site is then considered. The maximum likelihood(ML) method and a number of ad hoc counting methods are evaluated. The rest of the chapterdeals with joint analyses of multiple sequences on a phylogeny. Review is done on Markov modelsof codon substitution that allow the...

  3. Can CT measures of tumour heterogeneity stratify risk for nodal metastasis in patients with non-small cell lung cancer?

    Craigie, M; Squires, J; Miles, K
    AIM: To undertake a preliminary assessment of the potential for computed tomography (CT) measurement of tumour heterogeneity to stratify risk of nodal metastasis in patients with non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: Tumour heterogeneity in CT images from combined positron-emission tomography (PET)/CT examinations in 150 consecutive patients with NSCLC was assessed using CT texture analysis (CTTA). The short axis diameter of the largest mediastinal node was also measured. Forty-two patients without distant metastases subsequently had tumour nodal status confirmed at surgery (n=26) or endobronchial ultrasound (EBUS; n=16). CTTA parameters and largest nodal diameter were related to nodal status...

  4. Deep De-Aliasing for Fast Compressive Sensing MRI

    Yu, S; Dong, H; Yang, G; Slabaugh, G; Dragotti, PL; Ye, X; Liu, F; Arridge, S; Keegan, J; Firmin, D; Guo, Y
    Fast Magnetic Resonance Imaging (MRI) is highly in demand for many clinical applications in order to reduce the scanning cost and improve the patient experience. This can also potentially increase the image quality by reducing the motion artefacts and contrast washout. However, once an image field of view and the desired resolution are chosen, the minimum scanning time is normally determined by the requirement of acquiring sufficient raw data to meet the Nyquist-Shannon sampling criteria. Compressive Sensing (CS) theory has been perfectly matched to the MRI scanning sequence design with much less required raw data for the image reconstruction. Inspired...

  17. Loss of Appendicular muscle mass in haemodialysis patients is associated with increased self-reported depression, anxiety and lower general health scores.

    Alston, H; Burns, A; Davenport, A
    AIMS: Depressive symptoms are commonly reported by haemodialysis (HD) patients. Previous reports have suggested an association between depression and nutritional status. To investigate this, we measured muscle mass in HD patients screened for depression. METHODS: The Beck Depression Inventory-II (BDI-II), Hospital Anxiety and Depression Scale (HADS) were used to screen for depression, and quality of life assessed by the short form 36 (SF36), and measured appendicular lean mass (ALM) post-dialysis with segmental bioimpedance. RESULTS: We studied 113 patients, 84 (74.3%) male, mean age 64.9 ± 14.9 years, median duration of haemodialysis 27.0 (15.7-61.0) months, body mass index (BMI) post-dialysis 25.2 (22.8-28.6) kg/m(2) ,...

  20. Multidrug-resistant pandemic (H1N1) 2009 infection in immunocompetent child.

    Eshaghi, A; Patel, SN; Sarabia, A; Higgins, RR; Savchenko, A; Stojios, PJ; Li, Y; Bastien, N; Alexander, DC; Low, DE; Gubbay, JB
    Recent case reports describe multidrug-resistant influenza A pandemic (H1N1) 2009 virus infection in immunocompromised patients exposed to neuraminidase inhibitors because of an I223R neuraminidase mutation. We report a case of multidrug-resistant pandemic (H1N1) 2009 bearing the I223R mutation in an ambulatory child with no previous exposure to neuraminidase inhibitors.
