The authors explored cognitive functioning and suicidal behavior in older depressed patients. Inpatients age 50 years or older (N=103) with major depression, 45 of whom had attempted suicide, were evaluated within 1 week of their hospital admission. Measures of suicidal behavior included suicide attempter status, the Suicide Intent Scale (SIS), ratings of(More)
Knowledge is seen as a source of competitive advantage in organizations. The need to cater to global market places, competitive pressures and to avail the best resource possible has given rise to distributed form of working, which is further enabled by technological advances. The prime advantage of distributed form of working is access to diverse sources of(More)
We have investigated whether attenuated growth hormone (GH) and prolactin (PRL) responses to L-tryptophan in depression return to normal with clinical recovery. Ten patients who had received intravenous infusions of L-tryptophan (100 mg/kg) when depressed were retested at least 3 months after full recovery and cessation of treatment. In recovered(More)
There is circumstantial evidence that increases in prolactin secretion evoked by L-tryptophan infusion involve 5-HT1 receptors, whereas growth hormone responses do not. Propranolol is a beta-adrenoceptor antagonist that also possesses antagonist properties at 5-HT1 receptors. Propranolol (80 mg, PO) failed to attenuate the prolactin response to L-tryptophan(More)
A case of colloid cyst of the third ventricle in a patient presenting with delusional depressive syndrome, in clear consciousness and with minimal cognitive impairment, is reported. The possible pathogenesis of the syndrome is discussed in the light of the reported association between aqueduct stenosis, diencephalic dysfunction, hydrocephalus, and psychotic(More)
The Self Reporting Questionnaire (SRQ), a screening instrument developed for psychiatric disorders in developing countries, was administered to 149 mothers, half of whom where non-white, attending a well-baby clinic in Manchester, United Kingdom. Psychiatric interview confirmed that high scorers on the SRQ could be given DSM-III diagnoses of anxiety and(More)
BACKGROUND Prior work showed that administration of naloxone HCl had different behavioral effects in patients with Alzheimer's disease (AD) than controls. The aim of the present study was to contrast the physiologic and neuroendocrine responses to administration of a wide range of doses of intravenous naloxone of patients with probable Alzheimer's disease(More)
Recent advances in computer performance and affordability have accelerated their application to understanding biological phenomena. Computational models are now an integral part of biological and biomedical research. This paper presents a range of examples that illustrate the important role that computational simulation plays in research in the biological(More)
