Broccoli florets contain low levels of 3-methylsuphinylpropyl and 4-methylsulphinylbutyl glucosinolates. Following tissue disruption, these glucosinolates are hydrolysed to the corresponding isothiocyanates (ITCs), which have been associated with anticarcinogenic activity through a number of physiological mechanisms including the induction of phase II(More)
Inhalation of pollen grains and fungal spores leads to allergenic rhinitis and type I asthma mediated by IgE. The etiology of these conditions is due to the presence of substances that can induce anaphylactic processes in susceptible subjects. A combination of transmission electron microscopy with immunocytochemical methods was used to localize allergenic(More)
The immediate early gene product Arc (activity-regulated cytoskeleton-associated protein) is posited as a master regulator of long-term synaptic plasticity and memory. However, the physicochemical and structural properties of Arc have not been elucidated. In the present study, we expressed and purified recombinant human Arc (hArc) and performed the first(More)
A reversed-phase HPLC technique in combination with fluorescent detection is described for simulataneous quantification of the precolumn Dansyl derivatives of intracellular amines. The derivatives were stable for at least one week, kept protected from the light at −20 °C. The detection limit was between 1 and 5 pmol for all tested polyamines. Serotonin(More)
Plasma membrane redox systems seem to play a role in the control of cell growth. In fact, we have found that in mammary tumour cell lines the increase in the proliferation rate is accompanied by a decrease in the plasma membrane redox activity. The oxygen consumption rates, the glycolytic fluxes and other bioenergetic parameters have been studied in two(More)
