Evolutionary breeding of wheat for low input systems

Genetically diverse Composite Cross Populations (CCPs) may be useful in environmentally variable low-input systems as an alternative to pure varieties. They are formed by assembling seed stocks with diverse evolutionary origins, recombining these stocks by hybridisation, bulking the F1 progeny, and subsequent natural selection of the progeny in suc-cessive natural cropping environments. CCPs derived from either 10 high yielding parents (YCCPs), 12 high quality parents (QCCPs), or all 22 parents (YQCCPs), were grown at four sites (2 organic, 2 conventional) in the UK. The YCCPs out yielded the QCCPs, which had higher protein concentrations and Hagberg falling numbers. Although the CCPs performed within the range of the parents, they often performed better than the mean of the parents

Inter- and intra-rater reliabilities of the Beighton Score compared to the Contompasis Score to assess Generalised Joint Hypermobility

Objectives: Generalized Joint Hypermobility [GJH] is a common connective tissue disorder associated with a range of musculoskeletal complaints. An effective screening tool to assess GJH may influence our understanding and choice of management. Diagnosis is clinical, using tools such as the Beighton Hypermobility Score and the Contompasis Scoring System. The comparable reliability of these tools has not been previously reported. The aim of the present study was to compare the intra- and the inter-rater reliability of the Beighton Score to the Contompasis Score to assess GJH. Methods: This was an observational study assessing 36 pain-free participants; 27 females and nine males; aged 18–32 years. Participants were assessed in random order, by two researchers over two sessions to determine intra- and inter-rater analyses. Intraclass Correlation Coefficient [ICC] and weighted Kappa statistics were used to calculate the level of agreement. Results: The intra- [ICC: 0.71–0.82] and the inter- [ICC: 0.72–0.80] rater reliability of the Beighton Score was substantial to almost perfect. The Contompasis Score displayed substantial to almost perfect intra-rater [ICC: 0.73–0.82] reliability and moderate to substantial inter-rater [ICC: 0.58–0.62] reliability. Conclusions: The present study provides an indication of the measurement capabilities of the Beighton and Contompasis Scores. The Beighton score appears to be superior compared with the Contompasis score particularly based on inter-rater reliability

Premenstrual enhancement of snake detection in visual search in healthy women

It is well known that adult humans detect images of snakes as targets more quickly than images of flowers as targets whether the images are in color or gray-scale. When such visual searches were performed by a total of 60 adult premenopausal healthy women in the present study to examine whether their performance would fluctuate across the phases of the menstrual cycle, snake detection was found to become temporarily enhanced during the luteal phase as compared to early or late follicular phases. This is the first demonstration of the existence of within-individual variation of the activity of the fear module, as a predictable change in cognitive strength, which appears likely to be due to the hormonal changes that occur in the menstrual cycle of healthy women
