a genetic linkage map of human chromosome 9q. | a genetic linkage map of human chromosome 9q, spanning a sex-equal distance of 125 cm, has been developed by genotyping 26 loci in the venezuelan reference pedigree. the loci include 12 anonymous microsatellite markers reported by kwiatkowski et al. (1992), several classical systems previously assigned to chromosome 9q, and polymorphisms for the genes tenacin (hxb), gelsolin (gsn), adenylate kinase 1 (ak1), arginosuccinate synthetase (ass), abl oncogene (abl1), abo blood group (abo), and dopamin ... | 1992 | 1427899 |
adaptation and recovery from adaptation of the auditory nerve neurophonic (ann) using long duration tones. | the time course of the interaction between adaptation and the recovery from adaptation of the auditory nerve neurophonic (ann) responses was examined. the interaction between the process of recovery and the adaptation process of long probe tones which follow a masker, the so called whole tone recovery, was determined for the ann response for different silent intervals between masker offset and probe onset. the auditory nerve neurophonic (ann) reflects the ensemble response of phase-locked firing ... | 1992 | 1429255 |
in vitro culture of the strobilar stage of echinococcus granulosus of sheep and donkey origin from jordan. | protoscolices of echinococcus granulosus isolated from hydatid cysts of sheep and donkeys in jordan were cultured in vitro using a modified diphasic culture system. protoscolices from these two sources manifested differences in the mode of development, evagination and growth rates. protoscolices isolated from sheep cysts grew in vitro in the polyzoic direction up to the three- to four-segmented mature worms, reaching a length of 2.9 mm. in contrast, donkey protoscolices failed to develop beyond ... | 1992 | 1438153 |
cutaneous leishmaniasis in western venezuela caused by infection with leishmania venezuelensis and l. braziliensis variants. | between 1975 and 1987, epidemiological studies were carried out in several rural and urban communities in the central part of western venezuela, especially in the state of lara. 115 positive cultures were obtained from human cases and identified by their reactivity patterns to a cross-panel of specific monoclonal antibodies using a radioimmune binding assay; 53 were leishmania venezuelensis and 62 were l. braziliensis. most of these stocks were also characterized by isoenzyme electrophoresis, wh ... | 1992 | 1440772 |
genetic evidence that epizootic venezuelan equine encephalitis (vee) viruses may have evolved from enzootic vee subtype i-d virus. | an important question pertaining to the natural history of venezuelan equine encephalitis (vee) virus concerns the source of epizootic, equine-virulent strains. an endemic source of epizootic virus has not been identified, despite intensive surveillance. one of the theories of epizootic strain origin is that epizootic vee viruses evolve from enzootic strains. likely enzootic sources of vee virus occur in colombia and venezuela where many of the epizootic outbreaks of vee have occurred. we have d ... | 1992 | 1448915 |
high sensitivity of human melanoma cell lines to the growth inhibitory activity of mycoplasmal arginine deiminase in vitro. | arginine deiminase (ad) is a potent growth inhibitor for some but not all tumour cell lines in vitro. as ad catalyses the direct conversion of l-arginine to l-citrulline, the ad-sensitivity of various tumour cells might be attributed to the levels of urea cycle enzymes involved in l-arginine biosynthesis. this study demonstrated that human melanoma cells were highly sensitive to the growth inhibitory activity of ad. five melanoma cell lines tested also exhibited reduced argininosuccinate synthet ... | 1992 | 1450673 |
studies on rhinoestrus purpureus (diptera: oestridae) larvae infesting donkeys (equus asinus) in egypt. iii. pupal duration under controlled conditions. | the pupal duration of rhinoestrus purpureus was studied under variable degrees of temperature and relative humidity (rh). it was found that pupal duration was affected by temperature but not by rh. an increase in the temperature above 22 degrees c decreased the pupal duration: 26-27 days at 22 degrees c, 16-24 days at 27 degrees c, 13-15 days at 32 degrees c. at 37 degrees c, the pupated larvae failed to pupate and died. the deformity ratio of emerged flies was 25-30% at 22-32 degrees c, but it ... | 1992 | 1466135 |
epidemiological observations on stomach worms of donkeys in morocco. | over two consecutive years, weekly examinations for the presence of nematodes were conducted on 185 stomachs from donkeys originating mainly from the rabat, casablanca and settat regions of morocco. all the animals, except one, were infected by at least one of four helminth species. trichostrongylus axei was found in 93.5%, habronema muscae in 89.7%, h. majus in 85.4% and draschia megastoma in 1.1% of donkeys. most animals were infected by two (23.8%) or three (71.9%) species. high burdens of t. ... | 1992 | 1466146 |
the amino-acid sequence of two isoforms of alpha-lactalbumin from donkey (equus asinus) milk is identical. | the complete primary structure of donkey alpha-lactalbumin a and b has been determined by sequencing of the peptides obtained after tryptic, glu-c proteinase or cyanogen bromide cleavage. although preparative purification of alpha-lactalbumin by flat-bed isoelectric focusing gave two protein fractions a and b, their amino-acid sequence revealed no differences. donkey alpha-lactalbumin shows two, four and five differences in comparison to the horse alpha-lactalbumin a, b and c. thus donkey alpha- ... | 1992 | 1466791 |
elevated gene expression of argininosuccinate synthetase in peripheral lymphocytes from systemic lupus erythematosus (sle) patients. | argininosuccinate synthetase (ass) is a rate-limiting enzyme of urea cycle and functions primarily in the liver, whereas ass activity is hardly detected in normal lymphocytes. in this study, we examined the level of ass gene expression in peripheral blood lymphocytes (pbl) from human sle patients by amplification of reverse-transcribed mrna using the polymerase chain reaction. we have demonstrated that (a) approximately 40% of sle patients exhibited 2.5 to 5 times higher expression of ass gene i ... | 1992 | 1467433 |
molecular evidence for the origin of the widespread venezuelan equine encephalitis epizootic of 1969 to 1972. | venezuelan equine encephalitis (vee) virus is a mosquito-borne pathogen that has caused encephalitis in equine species and humans during sporadic outbreaks in the western hemisphere. the last, and most widespread, vee outbreak occurred in south america, central america, mexico and the u.s.a. (texas) during 1969 to 1972. we have cloned and sequenced the genome of a virulent vee subtype i-ab virus, strain 71-180, isolated in texas in 1971. thirty-four nucleotide differences were detected between t ... | 1992 | 1469368 |
