transplacentally exposed human and monkey newborn infants show similar evidence of nucleoside reverse transcriptase inhibitor-induced mitochondrial toxicity.effective reduction in maternal-fetal human immunodeficiency virus-1 (hiv-1) transmission has been achieved by administration of nucleoside reverse transcriptase inhibitors (nrtis) during pregnancy, and although most exposed children are clinically normal at birth, mitochondrial dysfunction has been reported. to examine mitochondrial integrity on a molecular level, we evaluated mitochondrial morphology by electron microscopy (em) and mitochondrial dna (mtdna) quantity in umbilical cords and cord ...200716538687
[the mammals of guinea as reservoirs and carriers of arboviruses].a great body of data on the fauna and ecology of wild mammals and their participation in the circulation of arboviruses were collected when the ecology of the latter of the republic of guinea was studied in 1978 to 1989. a hundred and eighteen species belonging to 10 orders were identified. over 2,000 biological specimens were virologically and serologically examined. six arboviruses were isolated. these included dugbe virus (from the hussar monkey cercopithecus (erythrocebus patas) and 5 viruse ...200616562748
variations in the structure of the prelunate gyrus in old world monkeys.anatomical and electrophysiological studies have revealed a complex organization in the macaque prelunate gyrus. we investigated the morphology and architecture of the prelunate gyrus in old world monkeys. in macaca nemestrina, we observed a sulcus crossing the prelunate gyrus within 2 mm of the vertical meridian representation. in other macaque species and other cercopithecines, we observed substantial variations in sulcal morphology across the prelunate gyrus. we did not find a sulcus in all s ...200616779809
evolution of an intronic microsatellite polymorphism in toll-like receptor 2 among primates.nonhuman primates express varying responses to mycobacterium tuberculosis: new world monkeys appear to be resistant to tuberculosis (tb) while old world monkeys seem to be particularly susceptible. the aim of this study was to elucidate the presence of the regulatory guanine-thymine (gt) repeat polymorphisms in intron 2 of toll-like receptor 2 (tlr2) associated with the development of tb in humans and to determine any variations in these microsatellite polymorphisms in primates. we sequenced the ...200616912902
a mobile element-based evolutionary history of guenons (tribe cercopithecini).guenons (tribe cercopithecini) are a species-rich group of primates that have attracted considerable attention from both primatologists and evolutionary biologists. the complex speciation pattern has made the elucidation of their relationships a challenging task, and many questions remain unanswered. sines are a class of non-autonomous mobile elements and are essentially homoplasy-free characters with known ancestral states, making them useful genetic markers for phylogenetic studies.200717266768
distribution and abundance of patas monkeys (erythrocebus patas) in laikipia, kenya, 1979-2004.patas monkeys may be especially vulnerable to local extinction because they live in relatively small, female-philopatric groups at low densities and are strongly polygynous. we assessed a patas monkey population in kenya's 9,700 km(2) laikipia district over 25 years, using data collected in 1979-1981 and 1992-2004. the data were based on intensive observations of three study groups, "on the ground" counts, and surveys of laikipia residents. in 1979-1981, a minimum of 415 patas monkeys lived in 1 ...200717397045

body mass distribution and gait mechanics in fat-tailed dwarf lemurs (cheirogaleus medius) and patas monkeys (erythrocebus patas).most quadrupeds walk with lateral sequence (ls) gaits, where hind limb touchdowns are followed by ipsilateral forelimb touchdowns. primates, however, typically walk with diagonal sequence (ds) gaits, where hind limb touchdowns are followed by contralateral forelimb touchdowns. because the use of ds gaits is nearly ubiquitous among primates, understanding gait selection in primates is critical to understanding primate locomotor evolution. the support polygon model [tomita, m., 1967. a study on th ...200717512970
erythrocebus patas monkey offspring exposed perinatally to nrtis sustain skeletal muscle mitochondrial compromise at birth and at 1 year of age.antiretroviral nucleoside reverse transcriptase inhibitors (nrtis), given to human immunodeficiency virus-1-infected pregnant women to prevent vertical viral transmission, have caused mitochondrial dysfunction in some human infants. here, we examined mitochondrial integrity in skeletal muscle from offspring of pregnant retroviral-free erythrocebus patas dams administered human-equivalent nrti doses for the last 10 weeks of gestation or for 10 weeks of gestation and 6 weeks after birth. exposures ...200717545213
despotic wild patas monkeys (erythrocebus patas) in kala maloue, cameroon.the socio-ecological model predicts that the quality, distribution, and patch size of food resources determines the dominance hierarchy of female monkeys based on the type of food competition they experience. comparative studies of closely related species have evaluated the socio-ecological model and confirmed its validity. for example, female patas monkeys in laikipia, kenya, form a nonlinear and unstable dominance hierarchy (i.e., egalitarian), whereas females of sympatric, closely related sav ...200817854072
metabolism and pharmacokinetics of the combination zidovudine plus lamivudine in the adult erythrocebus patas monkey determined by liquid chromatography-tandem mass spectrometric analysis.because of their similarity to humans, non-human primates constitute useful preclinical models in which to examine potential human drug toxicities. antiretroviral nucleoside reverse transcriptase inhibitor (nrti) toxicity is currently under investigation in erythrocebus patas monkeys, and whereas nrti pharmacokinetics have been studied in other monkey species, pharmacokinetics for zidovudine plus lamivudine (azt/3tc) dosing have not been reported in the patas. here we present 24 h serum pharmaco ...200817949768
variation in guenon skulls (i): species divergence, ecological and genetic differences.guenons are the most diverse clade of african monkeys. they have varied ecologies, include arboreal and terrestrial species, and can be found in nearly every region of sub-saharan africa. species boundaries are often uncertain, with a variable number of species and subspecies mostly recognised on the basis of their geographic distribution and pelage. if guenon soft tissue patterns show high variability, the same does not seem to hold for skull morphology. guenon skulls are traditionally consider ...200818191179

the fish fauna of anambra river basin, nigeria: species abundance and morphometry.the fish yields of most nigeria inland waters are generally on the decline for causes that may range from inadequate management of the fisheries to degradation of the water bodies. sustainable exploitation requires knowledge of the ichthyofaunal composition in the water bodies. we did a survey of fish species in anambra river basin for 22 months. fish samples were collected using four different gears -hook and line of size 13, caste nets, gill nets, and cages of mesh sizes of 50 mm, 75 mm, and 1 ...200919637699
interspecific and temporal variation of ant species within acacia drepanolobium ant domatia, a staple food of patas monkeys (erythrocebus patas) in laikipia, kenya.the ants that live in the swollen thorns (domatia) of acacia drepanolobium are staple foods for patas monkeys (erythrocebus patas). to obtain a better understanding of these insects as resources for patas monkeys, we sampled the contents of 1,051 swollen thorns (ant domatia) over a 22-month period from december 1999 to september 2001, in laikipia, kenya. first, we confirmed that of the four species of ants that live on a. drepanolobium, crematogaster sjostedti, the competitively dominant ant in ...200717487875
revisiting play elements and self-handicapping in play: a comparative ethogram of five old world monkey behavior has been viewed as a mixture of elements drawn from "serious" behavior, interspersed by ritualized play signals. two other types of play behaviors have been overlooked: patterns that are dissimilar from any serious behavior and patterns with self-handicapping character, that is, those that put the animal into unnecessary disadvantageous positions or situations. here the authors show that these 2 types of patterns can constitute a major part of play repertoire. from our own videorec ...200919685966
interspecies and intraspecies variations in the serotonin transporter gene intron 3 vntr in nonhuman primates.a variable number of tandem repeat (vntr) polymorphism based on a 16 or 17-bp unit has been reported in the third intron of the human serotonin transporter gene (5-htt). vntrs have been shown to affect the transcriptional activity of genes, and vntr polymorphisms possibly influence human personality and several psychoneurological disorders. to estimate the changes that occurred in the vntrs during primate evolution, we amplified and sequenced the regions that corresponded to the human vntrs in v ...200818204817
ocular oxyspirurosis of primates in zoos: intermediate host, worm morphology, and probable origin of the infection in the moscow zoo.over the last century, only two cases of ocular oxyspirurosis were recorded in primates, both in zoos, and two species were described: in berlin, germany, oxyspirura (o.) conjunctivalis from the lemurid microcebus murinus, later also found in the lorisid loris gracilis; in jacksonville, florida, o.

demography and life histories of sympatric patas monkeys, erythrocebus patas, and vervets, cercopithecus aethiops, in laikipia, kenya.mortality patterns are thought to be strong selective forces on life history traits, with high adult mortality and low immature mortality favoring early and rapid reproduction. patas monkeys (erythrocebus patas) have the highest potential rates of population increase for their body size of any haplorhine primate because they reproduce both earlier and more often. we report here 10 yr of comparative demographic data on a population of patas monkeys and a sympatric population of vervet monkeys (ce ...200920976285
an assessment of gum-based environmental enrichment for captive gummivorous the wild, many primates consume gums exuded from trees, and many species are gum specialists. in spite of this, few data exist concerning gum feeding in captivity. using a web-based survey of 46 zoos in 12 countries, we evaluated the extent to which zoos feed gum to primates. we found that although callitrichids and galagos receive gum-based enrichment, cercopithecines generally do not. environmental enrichment is important for stimulating naturalistic behavior to promote the psychological we ...201121319210
progressive mitochondrial compromise in brains and livers of primates exposed in utero to nucleoside reverse transcriptase inhibitors (nrtis).mitochondrial compromise has been documented in infants born to women infected with the human immunodeficiency virus (hiv-1) who received nucleoside reverse transcriptase inhibitor (nrti) therapy during pregnancy. to model these human exposures, we examined mitochondrial integrity at birth and 1 year in brain cortex and liver from offspring of retroviral-free erythrocebus patas dams-administered human-equivalent nrti doses for the last half (10 weeks) of gestation. additional infants, followed f ...201020702595
avoidance of mammalian predators by patas monkeys (erythrocebus patas) in a risk landscape.primates and felids often occupy the same landscape, hence evolutionary theory predicts that proximate predator-prey mechanisms will influence both groups' ecology. erythrocebus patas are potentially vulnerable to a number of predators and exhibit an array of morphological and behavioural predator avoidance strategies. here, two concurrent studies, one on e. patas and one on the mammalian carnivore assemblage, in the acacia drepanolobium woodland of sweetwaters game reserve (sgr), laikipia, keny ...201223363589
nutritional benefits of crematogaster mimosae ants and acacia drepanolobium gum for patas monkeys and vervets in laikipia, kenya.patas monkeys (erythrocebus patas) are midsized primates that feed extensively on the gum of acacia drepanolobium and the ants are housed in swollen thorns of this acacia. their diet resembles that expected more of smaller bodied primates. patas monkeys are also more like smaller bodied primates in reproducing at high rates. we sought to better understand the convergence of patas monkeys with smaller bodied primates by comparing their feeding behavior on ants and gum with that of closely related ...201223280312
