mode of processing and hemisphere differences in the judgement of musical stimuli.	the relationship between processing strategy and ear asymmetry was examined in two experiments in which subjects were required to make judgements about monoaurally presented musical chords. in the first experiment, subjects without musical training showed a significant left ear advantage while in those with musical training a significant shift towards a right ear advantage was observed. performance on the embedded figures test (eft) suggested a strong relationship between analytic processing sty ...	2009	2736338

lead toxicity and iron deficiency in utah migrant children.	we determined the frequency of presumptive iron deficiency and lead toxicity in 198 utah migrant children, ages 9-72 months, during the summer of 1985. there were no confirmed cases of lead toxicity. thirteen per cent of those tested and 30 per cent of the children ages 9-23 months were iron deficient. hematocrit determinations accurately predicted iron deficiency in only 35 per cent of the children confirmed to have this disorder via erythrocyte protoporphyrin screening.	2009	2650572

effect of psoralens and ultraviolet radiation on murine dendritic epidermal cells.	monofunctional psoralens produce less phototoxicity than bifunctional psoralens after ultraviolet a (uva) irradiation. we investigated the effect of repetitive treatments with angelicin (isopsoralen), a monofunctional psoralen, plus uva radiation (ipuva) on the number and morphology of dendritic epidermal cells (dec). this effect was compared with that of 8-methoxypsoralen plus uva radiation (puva), uva alone, and uvb radiation. c3h/hen mice were treated topically with the drugs three times/wk f ...	2008	2565931
ovarian suppression induced with buserelin or danazol in the management of endometriosis: a randomized, comparative study.	the effectiveness of buserelin (hoechst-roussel pharmaceuticals, inc., somerville, nj) (0.2 mg subcutaneously [sc] or 1.2 mg intranasally [in] per day) and danazol (800 mg per day) in inducing ovarian suppression for the management of endometriosis was compared in a prospective randomized study. during 6 months of treatment, peripheral follicle-stimulating hormone (fsh), luteinizing hormone (lh), and estradiol concentrations were suppressed to a similar degree in both groups. symptomatic improve ...	2008	2493400
use of indium-111 as a red cell label.	to select the most promising 111in chelate for use as a second red cell (rbc) label for comparison of the survival of autologous and allogeneic cells, 49 normal rbc samples were studied in vitro after being labeled with 111in-8-hydroxyquinolinol (111in-oxine) prepared by three different methods, 111in-tropolone, and 111in-acetylacetone. labeling efficiencies reached 99 percent and did not decline when the amount of 111in used was increased from 1.75 to 50 muci per ml of rbcs. storage of labeled ...	2008	2493173

fractionated ifosfamide therapy produces a time-dependent increase in ifosfamide metabolism.	1. fifteen patients received 1.5 g m-2 of ifosfamide intravenously over 0.5 h every day for 5 days. twenty-one courses of treatment were studied. plasma was assayed for ifosfamide by gas liquid chromatography and plasma alkylating activity was measured using the nitrobenzylpyridine (nbp) reaction. 2. a pharmacokinetic analysis revealed a significant decrease in the median (range) elimination half-life of ifosfamide from 7.2 (2.8-14.2) h on day 1 to 4.6 (2.3-7.7) h on day 5 (p less than 0.001, wi ...	2008	2271371

[measurement of orthodontic appliance force using prototype sensors].	in introductory remarks the most important biomechanical principles, which are relevant for the research, and conditions which must be satisfied presented in intraoral measuring of orthodontic forces were pointed out. first the aim of the research was defined, and then the investigation of mechanical properties of acrylics as a material for orthodontic appliances were carried out. the type of strain gauges, bonds and measuring system configurations, as well as measuring amplifiers and recording ...	2008	2635572
cystic neoplasms of the pancreas.	eight patients with cystic neoplasms of the pancreas were seen at four northern california hospitals between the years 1978 and 1986. three of the tumors were benign and five were malignant. three females, whose average age was 61 years, had cystadenomas. three females and two males, whose average age was 48 years, had mucinous cystadenocarcinomas. clinical presentations were similar among all patients. abdominal pain was a prominent feature. anorexia, weight loss, nausea and vomiting with a pal ...	2008	2446398
phytochrome from the green alga mesotaenium caldariorum. purification and preliminary characterization.	a method to purify the phytochrome photoreceptor from the unicellular green alga mesotaenium caldariorum is presented. preparative scale formation of algal protoplasts and controlled osmotic cell lysis have permitted separation of intact organelles from the phytochrome-enriched soluble protein fraction. we have utilized the observation that red light-absorbing (pr) and far-red light-absorbing (pfr) forms of phytochrome are differentially retained on an anion exchange matrix to purify m. caldario ...	2008	2324111
