The effect of a unilateral 6-hydroxydopamine (6-OHDA) lesion of the left medial forebrain bundle and 3 weeks treatment with L-DOPA of normal and 6-OHDA lesioned rats on CB1r mRNA expression was investigated by in situ hybridization. A 6-OHDA lesion of nigrostriatal pathway alone, confirmed by the loss of nigral tyrosine hydroxylase mRNA, did not alter CB1r(More)
The cause of neuronal cell death in Parkinson's disease is unknown but there is accumulating evidence suggesting that oxidative stress may be involved in this process. Current evidence shows that in the substantia nigra there is altered iron metabolism, decreased levels of reduced glutathione and an impairment of mitochondrial complex I activity. However,(More)
The cause of neuronal loss in patients with idiopathic Parkinson's disease is unknown. Oxidative stress and complex I deficiency have both been identified in the substantia nigra in Parkinson's disease but their place in the sequence of events resulting in dopaminergic cell death is uncertain. We have analysed respiratory chain activity, iron and reduced(More)
OBJECTIVE The aim was to clarify the mechanism of the following observations: (1) left ventricular pressure recordings during diastole have shown that the minimum pressure at the base is greater than that at the apex; (2) echocardiographic measurements of the short axis dimension of the left ventricle during early filling have shown that the maximum rate of(More)
Pulse wave velocity (PWV) is associated with heart rate variability (HRV) in 24–39-year-old men. This study of 40–65-year-old men ranging in moderate-to-vigorous physical activity levels investigated whether (a) PWV is related to spectral HRV, (b) using normalised units for HRV influences that relationship, and (c) HRV predicts PWV when other factors,(More)
Time-lapse photography was used to examine the effects of gamma-aminobutyric acid (GABA) on the outgrowth and motility of neurites in cultures from mouse spinal cord. GABA at concentrations of 100, 10 and 1 microM caused significant inhibition of neurite outgrowth and the motility of growth cones was significantly reduced by treatment with 100 and 10 microM(More)
Time-lapse photography was used to examine the effects of acetylcholine on the outgrowth and motility of neurites in cultures of mouse spinal cord. Addition of acetylcholine to the culture medium at concentrations of 100, 10 and 1 microM, caused inhibition of neurite outgrowth. Outgrowth rates were significantly different from those of controls at all(More)
The effect of a unilateral 6-hydroxydopamine (6-OHDA) lesion and/or repeated administration of levodopa (L-DOPA) to normal and 6-OHDA-lesioned rats on alpha-synuclein mRNA expression was investigated by in situ hybridization histochemistry. A 6-OHDA lesion of the nigro-striatal pathway alone, confirmed by the loss of nigral tyrosine hydroxylase mRNA(More)
A 46-year-old woman presented with a large abdominopelvic mass. Exploration revealed a large cystic mass that arose from the posterior leaf of the right broad ligament. The mass was lined by endometrial-like tissue and had an outer layer of smooth muscle that resembled myometrium. The inner wall was focally composed of a thick layer of intermixed smooth(More)
The excitatory amino acid glutamate has been shown to be toxic to a number of neuronal cell types both in vitro and in vivo. It has also been shown to be capable of controlling the development of neurons grown in vitro. Using time-lapse video microscopy techniques the effects of glutamate on the rate of neurite outgrowth and growth cone motility were(More)
