Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology

open access: yesBiological Reviews, EarlyView.
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

Callus induction and growth in transgenic potato genotypes

open access: yesAfrican Journal of Biotechnology, 2004
The aim of this study was to establish an effective protocol for callus induction from the potato genotypes (Solanum tuberosum L.) used and to investigate whether the transferred oxalate oxidase enzyme or transformation procedure has any effect on callus induction of transgenic lines of cultivar Desiree and Maris Bard.

Complex presentations of child conduct problems: Validation of a competency‐based model for clinical practice

open access: yesJCPP Advances, EarlyView.
Abstract Background Children with conduct problems often present with a range of complex needs and many factors have the potential to complicate the delivery of evidence‐based interventions for conduct problems. Little, however, is known about how to optimise the delivery of such interventions for complex cases, and there has been a lack of consensus ...

Establishment of in vitro regeneration system for leaves and petioles of Oxalis triangularis 'Purpurea'

open access: yesTechnology in Horticulture
To provide good acceptor materials for genetic transformation, the leaves and petioles of Oxalis triangularis 'Purpurea' were used as explants to establish a tissue culture system including callus induction, subculture, bulb induction, rooting, and ...

Effect of phytohormones on shoot apex and leaf explants of Withania somnifera (Ashwagandha) [PDF]

open access: yes, 2016
An efficient protocol for callus induction of Withania somnifera through in vitro culture of shoot apex and leaf explant was standardized. Of the various combinations of phytohormones evaluated, MS media supplemented with 6-furfuryl aminopurine (KIN) 0.5

Infant frontal alpha asymmetry predicts social attention and transdiagnostic risk for emotional reactivity

open access: yesJCPP Advances, EarlyView.
Abstract Background Differences in Frontal Alpha Asymmetry (FAA), derived from the electroencephalogram (EEG), have been associated with approach‐withdrawal behavior, although inconsistently. The current study examined how early patterns of FAA during the first 2 years of life relate to various socioemotional characteristics (at 2 years) and ultimately
