glucose-6 phosphate dehydrogenase mutations and haplotypes in various ethnic groups.	mutations that produce glucose-6-phosphate dehydrogenase (g6pd) deficiency have been identified in samples from patients with hemolytic disease in the united states, and in g6pd-deficient samples from greece, the canary islands, the czech and slovak republics, south china, and in samples from the coriell cell repository. eight new mutations are described. particularly unusual were a nonsense mutation ("g6pd georgia"1284a), a deletion of six bases ("g6pd stony brook" 724-729 del) coding for two a ...	1995	7803800
inner-ear abnormalities and their functional consequences in belgian waterslager canaries (serinus canarius).	recent reports of elevated auditory thresholds in canaries of the belgian waterslager strain have shown that this strain has an inherited auditory deficit in which absolute auditory thresholds at high frequencies (i.e. above 2.0 khz) are as much as 40 db less sensitive than the thresholds of mixed-breed canaries and those of other strains. the measurement of cap audiograms showed that the hearing deficit is already present at the level of the auditory nerve (gleich and dooling, 1992). here we sh ...	1994	7806475
contribution of neurons born during embryonic, juvenile, and adult life to the brain of adult canaries: regional specificity and delayed birth of neurons in the song-control nuclei.	neurogenesis occurs in adult song birds, which suggests that neurons born after hatching may contribute to histogenesis and plasticity of the avian brain. however, little is known about the overall contribution to the mature brain of neurons born in juveniles and adults, and how this process affects different regions of the avian brain. in fact, studies of the histogenesis of the avian forebrain have made the classical assumption that neuronal birth ends before hatching. here we determined the c ...	1994	7814666
immediate-early gene responses in the avian song control system: cloning and expression analysis of the canary c-jun cdna.	previous studies have shown that song presentation results in a rapid rise in mrna levels for the zenk gene (the avian homologue of zif-268, egr-1, ngfi-a, and krox-24) in specific parts of the songbird forbrain. metrazole-induced seizures also cause an increase in zenk mrna, even more widely throughout the telencephalon. surprisingly, however, little or no zenk induction by either stimulus was observed in several forebrain areas involved in auditory processing and song production. to learn whet ...	1994	7898314
uv-induced alterations in skin and lymphocytes during a one-week holiday in the canary islands in may.	the effect of solar exposure during a one-week sunbathing vacation in may at 29 degrees n latitude was investigated in 22 volunteers. the following end-points were measured before and after the holiday: skin reflectance at 507 nm, transmission of radiation from 289 nm to 448 nm through the epidermis, epidermal thickness, minimal erythema dose (med), total white cell, neutrophil, lymphocyte, and lymphocyte subpopulation counts in blood, spontaneous dna synthesis, dna strand breaks and sister-chro ...	1993	7906452
exogenous testosterone differentially affects myelination and neurone soma sizes in the brain of canaries.	we assessed the temporal and functional relationship of myelin maturation and of neuronal development in the telencephalic song motor centres of the canary at different developmental stages. brain differentiation was modulated by exogenous testosterone, its effects on song quality were also monitored. myelin maturation was studied by using computer aided analysis of silver impregnated brain sections, whereas the differentiation of neurones was determined by measuring neuronal soma sizes. at an e ...	1994	7948836
[urinary bilharziasis. comments on 10 cases].	urinary bilharziasis is a parasitic disease caused by schistosome haematobium which is prevalent in several african and middle east countries. the closeness of the canary islands to the african continent and a greater population mobility have allowed us to diagnose and treat ten patients, all of them natural of this region. this paper outlines the case-reports, and reviews this parasitic disease which seriously affects the urinary tract and which must be specifically contemplated both in emigran ...	1994	7976693
