| heterogeneity of hepatic microsomal udp-glucuronosyltransferase(s) activities: comparison between human and mammalian species activities. | the first comparative profiles of udp-glucuronosyltransferase(s) (udpgt) activities obtained under standard conditions in vitro in mammals (man, rat [wistar and gunn], mouse, monkey [papio papio and cynomolgus], pig, guinea pig, rabbit, dog) are presented for 16 aglycones. a decreasing scale of these activities was obtained from planar to bulky molecules. the scale was identical for each of the mammals studied, including man. statistical analysis of the results revealed a division of the aglycon ... | 1984 | 6439424 |
| genetic animal models of epilepsy as a unique resource for the evaluation of anticonvulsant drugs. a review. | genetic animal models of epilepsy comprise genetically predisposed animal species in which seizures either occur spontaneously or in response to sensory stimulation. the major advantage of these naturally occurring epilepsies in animals as models of human epilepsy is that they simulate the clinical situation more closely than any other experimental epilepsy. models with idiopathic spontaneous recurrent seizures are epileptic dogs, tottering mice, and rats with spike-wave absence (petit mal) seiz ... | 1984 | 6439966 |
| behavioural and convulsant actions of two methyl esters of beta-carboline-3-carboxylic acid in photosensitive baboons and in dba/2 mice. | the proconvulsant and convulsant actions of methyl 6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate (dmcm) and of methyl-beta-carboline-3-carboxylate (beta-ccm) have been evaluated in two animal models of reflex epilepsy, the photosensitive baboon, papio papio, and the audiogenic seizure prone dba/2 mouse. in baboons, myoclonic responses to photic stimulation are markedly enhanced 1 min after dmcm, 0.25 mg/kg i.v. in the absence of photic stimulation dmcm, 0.5 mg/kg i.v. induces a single brief ... | 1984 | 6499918 |

| high prevalence of antibodies against the bacterium treponema pallidum in senegalese guinea baboons (papio papio). | the bacterium treponema pallidum is known to cause syphilis (ssp. pallidum), yaws (ssp. pertenue), and endemic syphilis (ssp. endemicum) in humans. nonhuman primates have also been reported to be infected with the bacterium with equally versatile clinical manifestations, from severe skin ulcerations to asymptomatic. at present all simian strains are closely related to human yaws-causing strains, an important consideration for yaws eradication. we tested clinically healthy guinea baboons (papio p ... | 2015 | 26588087 |
| contrasted patterns of variation and evolutionary convergence at the antiviral oas1 gene in old world primates. | the oligoadenylate synthetase 1 (oas1) enzyme acts as an innate sensor of viral infection and plays a major role in the defense against a wide diversity of viruses. polymorphisms at oas1 have been shown to correlate with differential susceptibility to several infections of great public health significance, including hepatitis c virus, sars coronavirus, and west nile virus. population genetics analyses in hominoids have revealed interesting evolutionary patterns. in central african chimpanzee, oa ... | 2015 | 26156123 |

| intronic sequence motifs of hla-dqb1 are shared between humans, apes and old world monkeys, but a retroviral ltr element (dqltr3) is human specific. | long terminal repeats (ltrs) of the human endogenous retrovirus k (herv-k) family have been found at several sites within the human genome, of which one is located in the vicinity of hla-dqb1. since this dqltr3 is only present on some haplotypes, we performed a linkage analysis in 130 caucasian families. in order to date the integration event we also investigated the presence of this dqltr3 in apes and old world monkeys. additionally, we sequenced the adjacent region of dqltr3-positive and -nega ... | 1999 | 10395105 |
| mfasat: a new alphoid dna sequence isolated from macaca fascicularis (cercopithecidae, primates). | a new highly repeated dna fragment isolated from macaca fascicularis (mfasat) is described. our findings obtained by sequencing, southern blot analysis, and fluorescent in situ hybridization (fish) on metaphasic chromosomes strongly suggest that mfasat can be considered as a member of the alphoid dna family characteristic of old world monkeys. the chromosomal localization of mfasat, obtained by fish, showed that this alphoid dna is present in the peri-centromeric area of all the chromosomes. mfa ... | 1999 | 10659771 |
| chimpanzees routinely fish for algae with tools during the dry season in bakoun, guinea. | wild chimpanzees regularly use tools, made from sticks, leaves, or stone, to find flexible solutions to the ecological challenges of their environment. nevertheless, some studies suggest strong limitations in the tool-using capabilities of chimpanzees. in this context, we present the discovery of a newly observed tool-use behavior in a population of chimpanzees (pan troglodytes verus) living in the bakoun classified forest, guinea, where a temporary research site was established for 15 months. b ... | 2017 | 27813136 |

| pictorial gaze cues do not enhance long-tailed macaques' performance on a computerised object-location task. | the perception of pictorial gaze cues was examined in long-tailed macaques (macaca fascicularis). a computerised object-location task was used to explore whether the monkeys would show faster response time to locate a target when its appearance was preceded with congruent as opposed to incongruent gaze cues. despite existing evidence that macaques preferentially attend to the eyes in facial images and also visually orient with depicted gaze cues, the monkeys did not show faster response times on ... | 2006 | 16962253 |
| processing of biological motion point-light displays by baboons (papio papio). | humans apply complex conceptual judgments to point-light displays (plds) representing biological motion (bm), but how animals process this kind of display remains uncertain. four baboons (papio papio) were trained to discriminate bm from nonbiological motion plds using an operant computerized test system. transfer tests were given after training with novel bm stimuli representing humans or baboons (experiment 1), with inverted plds (experiment 2), and with bm stimuli in which body parts had been ... | 2007 | 17924787 |

| relational matching in baboons (papio papio) with reduced grouping requirements. | analogical reasoning is a corner stone of human cognition, but the phylogenetic origins of this skill are still unknown. recent animal studies have suggested that only apes can solve the 2- by 2-item relational matching (rmts) analogy problem, with potential benefits of language- (premack, 1983) or token-training procedures (thompson, oden, & boysen, 1997). in this study, 6 baboons were initially trained in an rmts task in which the same and different relations were exemplified by compound stimu ... | 2010 | 20384399 |
| automated testing of cognitive performance in monkeys: use of a battery of computerized test systems by a troop of semi-free-ranging baboons (papio papio). | fagot and paleressompoulle (2009) published an automated learning device for monkeys (aldm) to test the cognitive functions of nonhuman primates within their social groups, but the efficiency of the aldm procedure with large groups remains unknown. in the present study, 10 aldm systems were provided ad lib to a troop of 26 semi-free-ranging baboons that were initially naive with computerized testing. the test program taught baboons to solve two-alternative forced choice (2afc) and matching-to-sa ... | 2010 | 20479182 |
| hemispheric lateralisation and global precedence effects in the processing of visual stimuli by humans and baboons (papio papio). | this paper examines the effect of global precedence (gpe: navon, 1977) and its lateralisation from a comparative perspective. using a divided field matching-to-sample task with compound stimuli, experiment 1 demonstrated consistent patterns of lateralisation in humans and baboons, corresponding to a right-hemisphere advantage for global processing and a left- but nonsignificant advantage for local processing. species differences emerged in terms of gpe; humans showed a global precedence effect, ... | 1997 | 15513066 |
| generalized relational matching by guinea baboons (papio papio) in two-by-two-item analogy problems. | analogical reasoning is considered the hallmark of human reasoning, but some studies have demonstrated that language- and symbol-trained chimpanzees can also reason analogically. despite the potential adaptive value of this ability, evidence from other studies strongly suggests that other nonhuman primates do not have this capacity for analogical reasoning. in our three experiments, 6 of 29 baboons acquired the ability to perform a relational matching-to-sample (rmts) task in which pairs of shap ... | 2011 | 21934135 |
| Age-dependant behavioral strategies in a visual search task in baboons (Papio papio) and their relation to inhibitory control. | A computerized visual search task was presented to 18 guinea baboons (Papio papio) ranging from 2.7 to 14.3 years of age. The task, inspired from Hick's (1952) task, required detection of a target among a variable number of distractors equidistant to a start button. The reaction times (RTs) and movement times both increased with the number of distractors expressed in bits of information. However, the slope of RT per bit function correlated positively with age, whereas a negative correlation was ... | 2011 | 22142038 |
| Hair cortisol levels track phylogenetic and age related differences in hypothalamic-pituitary-adrenal (HPA) axis activity in non-human primates. | Hair has been shown to archive a uniquely time averaged signal of endocrine activity, and holds attractive advantages for both laboratory and field research. Prior research has explored the potential of hair hormone analysis to examine hormone-behavior relationships. To date, no research has focused on the potential of the technique to investigate age-related changes or taxon differences in endocrine function. It is known that non-human primate infants of many taxa exhibit high cortisol levels a ... | 2011 | 21893059 |
| centre-embedded structures are a by-product of associative learning and working memory constraints: evidence from baboons (papio papio). | influential theories have claimed that the ability for recursion forms the computational core of human language faculty distinguishing our communication system from that of other animals (hauser, chomsky, & fitch, 2002). in the present study, we consider an alternative view on recursion by studying the contribution of associative and working memory processes. after an intensive paired-associate training with visual shapes, we observed that baboons spontaneously ordered their responses in keeping ... | 2012 | 22225966 |
| effects of melatonin on the photosensitive epilepsy of the baboon, papio papio. | the acute pharmacological effects of melatonin (5-methoxy-n-acetyl-tryptamine) were evaluated on behaviour and electrographic signs in the photosensitive baboon (papio papio), including visually evoked potentials veps). doses of 5 and 10 mg/kg i.v. had little effect, contrasting with the enhancement of spontaneous paroxysmal activity and latency of clinical signs elicited by intermittent light stimulation (ils) produced by the 20 and 50 mg/kg doses. moreover, a modification of the electrographic ... | 2001 | 60219 |
| localization of fcgr1 encoding fcgamma receptor class i in primates: molecular evidence for two pericentric inversions during the evolution of human chromosome 1. | the human high-affinity receptor for immunoglobulin g, fcgammari (fcgr1), is encoded by a family of three genes that share over 95% sequence homology. curiously, the three genes in this recently duplicated gene family flank the centromere of human chromosome 1, with fcgr1b located at 1p12 and both fcgr1a and fcgr1c located at 1q21. we have previously speculated that a pericentric inversion could account for the separation of the genes in the fcgr1 family and explain their current chromosomal loc ... | 1998 | 9763663 |
| comparative assessment of distance processing and hemispheric specialization in humans and baboons (papio papio). | this comparative study explored the ability to process distance and its lateralization in humans and baboons. using a conditional matching-to-sample procedure in a divided-field format, subjects had to decide whether or not the distance between a line and a dot belonged to a short- or a long-distance category. experiments 1, 2, and 4 demonstrated the ability of baboons to process and categorize distances. moreover, humans showed better distance processing for right visual field/left hemisphere p ... | 1998 | 9853095 |
