Abstract
One of the major environmental concerns over genetically modified (GM) crops relates to transgene movement into wild relatives. The pattern of hybridization ultimately affects the scale and rapidity of ecological change and the feasibility of containment. A new procedure for quantifying hybrid formation over large areas is described. Remote sensing was used to identify possible sites of sympatry between Brassica napus and its progenitor species across 15 000 km2 of south-east England in 1998. Two sympatric populations with B. rapa and one with B. oleracea were found over the entire survey area. Every newly recruited plant in these populations in 1999 was screened for hybrid status using flow cytometry and molecular analyses. One hybrid was observed from the 505 plants screened in the B. rapa populations but none of the nine B. oleracea recruits were hybrids. Measures to minimize gene flow are suggested, and a procedure for the post-release evaluation and containment of GM cultivars is proposed.

Abstract
Standard ambulatory night sleep electroencephalograph (EEG) of 11 long-term practitioners of the Transcendental Meditation (TM) program reporting "higher states of consciousness" during sleep (the experimental group) was compared to that of nine short-term practitioners and 11 non-practitioners. EEG tracings during stages 3 and 4 sleep showed the experimental group to have: 1) theta-alpha activity simultaneously with delta activity and 2) decreased chin electromyograph (EMG) during deep sleep (p = 0.002) compared to short-term practitioners. Spectral analysis fast Fourier transform (FFT) data of the first three cycles showed that: 3) the experimental subjects had significantly greater theta 2 (6-8 Hz)-alpha 1 (8-10 Hz) relative power during stages 3 and 4 than the combined control groups [t(30) = 5.5, p = 0.0000008] with no difference in time in delta; 4) there was a graded difference across groups during stages 3 and 4 in theta 2-alpha 1 power, with experimentals having greater power than short-term practitioners, who in turn had greater power than non-practitioners [t(30) = 5.08, p = 0.00002]; and 5) experimentals also had increased rapid eye movement (REM) density during REM periods compared to short-term practitioners (p = 0.04). Previous studies have found increased theta-alpha EEG activity during reported periods of "transcendental consciousness" during the TM technique. In the Vedic tradition, as described by Maharishi Mahesh Yogi, transcendental consciousness is the first of a sequence of higher states. The maintenance of transcendental consciousness along with deep sleep is said to be a distinctive criterion of further, stabilized higher states of consciousness. The findings of this study are interpreted as physiological support for this model.

Abstract
An automated system providing quantitative measurements of C-band size has been used, in conjunction with statistical methodology developed for the purpose, in a family study to demonstrate its potential in determining the mode of transmission of C-bands from parent to offspring, and to test the assumption of Mendelian inheritance. The most serious obstacle encountered was the high within-person variance of the normalized band sizes, the large within-slide variance being increased by technical variation between different preparations. Attempts to reduce variance by developing more effective normalization techniques did not prove fruitful. Nevertheless, the ability of the present system to perform a trace using a reasonable number of cells has been demonstrated in an example. In the two families studied we saw no evidence that band size was not transmitted and changes in band size, if any, were less than about 5 micrometer2 X 10(-2) (compared to a typical medium-category band size of about 65 mcirometer2 X 10(-2)).

Abstract
Vectorcardiographic variables have been studied in patients with sex chromosome abnormalities and compared with normal controls. Several of these variables were found to be correlated with the number of sex chromosomes in the karyotype, some being related to the number of X chromosomes, some to the number of Y chromosomes, and others to both. The variables concerned included time intervals and vector magnitudes in both the QRS and ST-T wave complexes. The heart rate itself proved dependent on both the X and the Y chromosome complements. The correlations could not be explained by age, height, or weight differences between the seven different karyotype groups studied. The dependences of variables other than the heart rate remained after correction for between-group heart rate differences. The findings are discussed.
