Introduction The role of ethylene in regulating the expression of Tomato fruit ripening involves complex gene expression three lipoxygenase (LOX) genes TomloxA, TomloxB and and biochemical changes which ultimately result in altera-TomloxC during fruit ripening has been investigated. tions to the physical properties of the fruit giving rise to The study used(More)
Afferents to the nucleus accumbens have been studied with the retrograde transport of unconjugated wheatgerm agglutinin as detected by immunohistochemistry using the peroxidase-antiperoxidase method, in order to define precisely afferent topography from the cortex, thalamus, midbrain and amygdala. Cortical afferent topography was extremely precise. The(More)
Tobacco (Nicotiana plumbaginifolia) seedlings genetically transformed to express apoaequorin were incubated in h-coelenterazine to reconstitute the calcium-sensitive luminescent protein aequorin. Treatment of these seedlings with hydrogen peroxide resulted in a transient burst of calcium-dependent luminescence lasting severa1 minutes. Even though the(More)
Pituitary glands of pro-oestrous and oestrous rats were perifused in series with isolated ovarian follicles and the luteinizing hormone (LH) and follicle-stimulating hormone (FSH) responses to gonadotropin-releasing hormone (GnRH) were measured. Pituitary glands from pro-oestrous rats, perifused with the effluent medium from isolated preovulatory follicles,(More)
The purpose of this study was to assess the reliability of a pre-loaded 1 500-m treadmill time trial, conducted in moderate normobaric hypoxia. 8 trained runners/triathletes (24±3 years, 73.2±8.1 kg, 182.5±6.5 cm, altitude specific V˙O2max: 52.9±5.5 ml·kg(-1)·min(-1)) completed 3 trials (the first as a familiarisation), involving 2, 15-min running bouts at(More)
A method for demonstrating the anterograde and retrograde transport of unconjugated lectins in the CNS is given using the labelled antibody enzyme technique. Successful labelling of a variety of pathways is demonstrated using wheat germ agglutinin (WGA) and concanavalin A (Con A). Exceptionally large numbers of neurones labelled by retrograde transport were(More)
