| effect of protein diets on the renal function of baboons (papio hamadryas) with remnant kidneys: a 5-year follow-up. | to assess the progression of renal disease and the effects of protein intake in a species phylogenically close to humans, 14 adolescent baboons (papio hamadryas) were subjected to infarction of one third of the left kidney and, 2 months later, to right nephrectomy. they were then randomized to a synthetic protein diet containing either 8% or 25% casein. hemodynamic and metabolic measurements were obtained in awake animals every 4 months. modest proteinuria developed immediately after left kidney ... | 1994 | 8311075 |
| the sukhumi primate monkey model for viral lymphomogenesis: high incidence of lymphomas with presence of stlv-i and ebv-like virus. | t-cell leukemia virus-like proviral sequences (stlv-i) as well as ebv-like sequences were detected in pbls and tissues of non-human primates (papio hamadryas baboons, green monkeys and macaca arctoides; sukhumi primate center/georgia) by pcr. surprisingly, two different types of stlv-i within papio hamadryas baboons were found. one of its represents the baboon prototype stlv-i-su described earlier, present in lymphomatous baboons from the "high-lymphoma stock", which shows about 83% homology to ... | 1993 | 8395624 |
| corticotropin-releasing hormone in baboon pregnancy. | during human pregnancy, plasma crh immunoreactivity (crh-ir) rises progressively, peaking during labor and falling after delivery. among animal species, only higher primates have elevated crh-ir during pregnancy. this study examines whether changes in plasma crh-ir in the baboon (papio hamadryas) are similar to those in the human. crh-ir was determined by ria in 16 baboons at different stages of gestation (44 samples) and in 3 males. assays were performed on vycor extracts of plasma and crh-ir d ... | 1993 | 8473382 |
| linkage mapping in papio baboons: conservation of a syntenic group of six markers on human chromosome 1. | we have established multipoint genetic linkage among six loci in baboons (papio hamadryas). published pcr primers designed to amplify five human microsatellite loci were used to amplify homologous loci in 229 pedigreed baboons. southern blotting was used to type two rflps in a functional gene (anti-thrombin iii) in a subset of those animals. all six loci are known to map to human chromosome 1q, a region of the genome predicted by karyotype studies to be conserved in baboons. pairwise recombinati ... | 1995 | 8530033 |
| zoonotic intestinal parasites of hamadryas baboons papio hamadryas in the western and northern regions of saudi arabia. | six hundred and thirty-three faecal samples were randomly collected and examined for ova and cysts of intestinal parasites from five groups of hamadryas baboons of different population densities, with different human contact and in different ecological conditions (al-baha, turabah and al-taif in south-western and al-rihat and al-akhal in north-western saudi arabia). nine parasites were recorded (giardia lamblia, entamoeba histolytica, escherichia coli, balantidium coli, enterobius sp., trichuris ... | 1995 | 8544227 |
| androgens regulate circulating levels of insulin-like growth factor (igf)-i and igf binding protein-3 during puberty in male baboons. | to examine the role of androgens in initiating the pubertal rise in circulating insulin-like factor-i (igf-i) levels, a longitudinal study of puberty in 13 male hamadryas baboons was conducted over 3 yr. the five control baboons commenced puberty (initial testicular enlargement) at a mean +/- se age of 4.2 +/- 0.4 yr. another eight baboons were castrated prepubertally; of those four received testosterone pellets (dose equivalent: 12.5-50 mg every 6 weeks) implanted se from the time of puberty. b ... | 1996 | 8550796 |
| failure of experimental infection of baboons (papio hamadryas) with the eggs of asian taenia. | the infectivity of the eggs of asian taenia sp. for humans is not known. using baboons (papio hamadryas) as a model to extrapolate the findings, three animals were exposed per os with 1000, 10,000 and 50,000 infective eggs of the asian taenia sp. the serological, biochemical, haematological and parasitological (based on necropsy) results show that baboons are refractory to the infection. it is concluded that the asian taeniid eggs may fail to develop in man. | 1995 | 8583131 |
| [standardization of conditions for the evaluation of effectiveness of antibacterial drugs in pneumonic plague in sacred baboons]. | the signs of pneumonic plague in sacred baboons infected by aerosol are: fever, hurried breathing, depression and constantly increasing bacteremia. some infected animals isolate the plague microbes while coughing and thus could be a source of the infection. by the clinical and pathomorphological signs, pneumonic plague in sacred baboons is similar to that in humans which makes it possible to use the animals in the development of schemes for special prophylaxis and treatment of the disease. in ef ... | 1995 | 8593090 |
| the presence of a divergent t-lymphotropic virus in a wild-caught pygmy chimpanzee (pan paniscus) supports an african origin for the human t-lymphotropic/simian t-lymphotropic group of viruses. | we isolated a divergent simian t-lymphotropic virus (stlv) (strain pp1664) from a wild-caught african bonobo (pygmy chimpanzee, pan paniscus). molecular and phylogenetic characterization of this virus show that it reliably separates from the two well-established primate t-lymphotropic virus types, htlv-i/stlv-i (ptlv-i) and ptlv-ii, and from a third type isolated from an african-born papio hamadryas and designated by us as ptlv-l. four of eight bonobos kept at the antwerp zoo, belgium, showed an ... | 1996 | 8609475 |
| influence of neuropeptides on the processes of higher nervous activity in primates. the action of cyclic analogs of enkephalins on the behavior of the lower monkeys. | the effect of two cyclic enkephalin analogs (ivs-43 and ivs-46) on the group and individual behavior of rhesus macaques and hamadryas baboons has been studied. a pronounced influence of ivs-46 on competitive and operant goal-directed behavior of the monkeys was identified. | 1995 | 8614479 |
| the genomic structure of a new simian t-lymphotropic virus, stlv-ph969, differs from that of human t-lymphotropic virus types i and ii. | a new simian t-lymphotropic virus, stlv-ph969, was recently isolated from a wild-born hamadryas baboon. previous analysis had revealed that it differs sufficiently from the other htlv/stlvs to be considered a new type, provisionally designated primate t-lymphotropic virus-l. here we analyse a 3850 bp cdna fragment spanning the 3' part of the stlv-ph969 genome. the fragment encodes three major proteins: env, tax and rex. sequence comparison and phylogenetic analysis indicate that in general stlv- ... | 1996 | 8627239 |
| the three human t-lymphotropic virus type i subtypes arose from three geographically distinct simian reservoirs. | to investigate the origin of human t-lymphotropic virus i (htlv-i), strains of diverse geographical origin were analysed. we sequenced the ltr and env genes of htlv-i strains from brazil, central african republic, taiwan and zaire, and the simian t-lymphotropic virus type i (stlv-i) strain phsu1 from a baboon from the sukhumi primate centre. we performed phylogenetic analyses using neighbour-joining, parsimony and maximum likelihood methods. three separate htlv-i clusters were identified intersp ... | 1996 | 8627240 |
| interspecies transmission of macaque simian t-cell leukemia/lymphoma virus type 1 in baboons resulted in an outbreak of malignant lymphoma. | an outbreak of malignant lymphoma has been observed in one of the baboon (papio hamadryas) stocks of sukhumi primate center. more than 300 cases in this "high-lymphoma stock" have been registered since 1967. human t-cell lymphotropic virus type 1 (htlv-1)-related virus was implicated as the etiologic agent of sukhumi baboon lymphoma. the origin of this virus remained unclear. two possibilities were originally considered: the origin could be baboon simian t-cell leukemia/lymphoma virus type 1 (st ... | 1996 | 8627684 |
| low blood protein heterozygosity in zoo-bred hamadryas baboons. | an electrophoretic study of erythrocyte allozymes and serum proteins representing 32 genetic loci in 32 hamadryas baboons (papio h.hamadryas) from cologne and frankfurt zoos revealed biallelic polymorphism in phosphoglucomutase (pgm), mannose phosphate isomerase (mpi) and transferrin (tf). polymorphism amounted to p = 0.097 over 31 loci and observed heterozygosity to h(o) = 0.011, indicating significant reduction from the respective gene diversity parameters encountered in free-living hamadryas ... | 1996 | 8653592 |
