The meristematic mitotic cells of plant roots are appropriate and efficient cytogenetic materials for the detection of clastogenicity of environmental pollutants, especially for in situ monitoring of water contaminants. Among several cytological endpoints in these fast dividing cells, such as chromosome/chromatid aberrations, sister-chromatid exchanges and(More)
Phase diagrams representing lateral phase separations in the plane of lipid bilayer membranes have been determined for binary mixtures containing dielaidoylphosphatidylcholine together with dimyristoylphosphatidylcholine, dipalmitoylphosphatidylcholine, distearoylphosphatidylcholine, dioleoylphosphatidylcholine, and dipalmitoylphosphatidylethanolamine. The(More)
We studied 11 patients with stable multiple sclerosis (MS) with major depression in terms of response to Sertraline at 100 mg q.d. in an open label trial. Patients were evaluated with self assessment measurements (Carroll scale) prior to and during treatment. Only one patient discontinued the drug during the three month treatment trial, and this was due to(More)
OBJECTIVE The current study sought to determine whether there were any significant cross-cultural differences in medical-physical findings, or in psychosocial, behavioral, vocational, and avocational functioning, for chronic low back pain patients. DESIGN Partially double-blind controlled comparison of six different culture groups. SETTING Subjects were(More)
A cytogenetic study of 27 spontaneous abortions was carried out using the Q-banding technic. The specimens were selected for study in order to increase the likelihood of finding a chromosome anomaly. Sixteen of 27 specimens (59%) showed a chromosome abnormality. Trisomy was found in 9 of the specimens, and the chromosomes involved were Nos. 2, 8, 14, 16,(More)
Retrospective review of affective disturbances in 238 patients with multiple sclerosis (MS) seen over a 6-month period revealed: 1) 51 patients (22%) received pharmacologic treatment for depressive symptoms during or within 4 years of the study period, and 17 (7%) received treatment for rapid mood swings; 2) among the 51 depressed patients, response rate to(More)
A dual monitoring system composed of the Tradescantia-Micronucleus (Trad-MCN) and Tradescantia-Stamen-Hair-Mutation (Trad-SHM) bioassays was utilized to monitor directly the genotoxicity of the gaseous emission at a closed landfill site and around an incinerator. Four of the commonly emitted gaseous agents from the landfill flare pipes, i.e. toluene,(More)
The use of catecholamine precursors and agonists in the attention deficit disorder and various biochemical studies have implicated deficient catecholamine metabolism in the pathogenesis of this illness. The amino acid L-tyrosine, a catecholamine precursor, is capable of augmenting central dopamine norepinephrine. Study of its use in the treatment of the(More)
Seven patients with refractory seizure disorders and neuropsychiatric symptoms believed secondary to felbamate are presented. Five were on concomitant valproic acid (and other agents). Anergia, apathy, bradyphrenia, and increased irritability were prominent. One patient on felbamate monotherapy had a new-onset psychosis. Felbamate's NMDA receptor antagonism(More)
