    Cyclooxygenase 2 (COX2) expression is associated with poor outcome in ER-negative, but not ER-positive, breast cancer (2004)

    Notes: Aims:  Inflammation and hormonal signalling induce cyclooxygenase 2 (COX2) expression in solid tumours. COX2 expression is linked to neovascularization and tumour growth. HER2 modulates colorectal cancer COX2 expression. We investigated interactions between COX2 and HER1–4 in breast cancer.Methods and results:  COX2 expression was localized to epithelial cells with 21.2% of cases expressing higher levels than normal epithelium. Elevated COX2 expression was not associated with size, grade, high Nottingham prognostic index (NPI) or oestrogen receptor (ER) negativity. No association was observed between COX2 and HER1–4 expression. High COX2 expression was associated with reduced disease-free survival (P = 0.03) and disease-related survival in ER-negative (P = 0.046) but not ER-positive disease (P = 0.835).Conclusion:  HER1, 2, 3 and 4 are not associated with high breast tumour COX2 expression. COX2 is frequently expressed in breast carcinoma cells and adjacent epithelium. COX2 may be an important factor in promoting tumour progression in ER-negative tumours and a potential drug target in breast tumours.

    Driving reaction time after right knee arthroscopy (2000)

    Notes: Abstract Driving reaction times of 30 right knee arthroscopy patients were measured using a computer-linked car simulator. Each patient was tested pre-operatively and ¶1 week after and 4 weeks after arthroscopy. As controls, 25 normal subjects were also tested. In the control group the average reaction time was 634 ms; the measurements at ¶1 week and at 4 weeks were 550 ms and 582 ms, respectively. In the arthroscopy group the average reaction time pre-operatively was 736 ms; the measurements 1 week and ¶4 weeks post-operatively were 920 ms and 685 ms, respectively. Two clinical tests (the stepping and standing tests) were also performed at each assessment. Statistical analysis showed a good correlation between these and reaction time. We conclude that it is appropriate for patients to delay their return to driving for at least 1 week, and that the actual timing of return to driving may be determined by performance on these two clinical tests.

    Notes: Abstract The non-linear differential equation $$\ddot x + p(t)x^3 = 0$$ , wherep(t) is a periodic square wave function of time with period τ, has been integrated by using a table of Jacobian elliptic functions. In the neighborhood of a typical elliptic fixed point, namely that for 11τ, 12-decimal accuracy has been used to determine a region which is stable.

    The stability of an area-preserving mapping (1972)
    Springer

    Notes: Abstract In many cases, the evolution of a Hamiltonian system can be represented by an area-preserving mapping of the plane onto itself. The stability or instability of the dynamical system is reflected in the derived mapping. The mappingT(x, y)=(x', y'): $$\begin{gathered} x\prime = x + a(y - y^3 ) \hfill \\ y\prime = y - a(x\prime - x\prime ^3 ) \hfill \\ \end{gathered} $$ was studied in order to determine methods of readily compartmentalizing the plane into regions of stable and unstable behavior under many applications ofT, without resorting to costly and frequently inaccurate methods requiring computation of thousands of maps. The concept of separatrices, which exist for perfectly integrable systems, is replaced by the more general idea of extended eigenvectors from hyperbolic fixed points of the mappings, where the eigenvectors are those of the matrix representing the mapping linearized in the neighborhood of the fixed point. It was demonstrated by Bartlett that these extended eigenvectors, or eigencurves, from neighboring hyperbolic fixed points, may intersect each other to form intricate networks of intersecting loops. This area will be stable if the ratio of loop area to cell area is very small, of the order of 10−5 for the above mapping. Generally, if the oscillation cannot be seen, one should act as if the entire area of the cell is stable.

    Notes: Abstract Spatially extensive analysis of satellite, climate, and census data reveals human-environment interactions of regional or continental concern in the United States. A grid-based principal components analysis of Bureau of Census variables revealed two independent demographic phenomena, α-settlement reflecting traditional human settlement patterns and β-settlement describing relative population growth correlated with recent construction in non-agricultural areas, notably in coastal, desert, and “recreational” counties and around expanding metropolitan areas. Regression tree analysis showed that β-settlement was differentially associated with five distinct combinations of seasonality, summer heat or cool, intensity of agriculture, and extent of “barren” land. Beta-settlement was greatest in coastal and desert areas, and coincided with national concentrations of threatened and endangered species.
