an evolutionary relationship between stearoyl-coa desaturase (scd) protein sequences involved in fatty acid metabolism.	stearoyl-coa desaturase (scd) is a key enzyme that converts saturated fatty acids (sfas) to monounsaturated fatty acids (mufas) in fat biosynthesis. despite being crucial for interpreting scds' roles across species, the evolutionary relationship of scd proteins across species has yet to be elucidated. this study aims to present this evolutionary relationship based on amino acid sequences.	0	26989730

identification and measurement of urinary estrone, estradiol-17 beta, estriol, pregnanediol and androsterone during the menstrual cycle of the orangutan.	urinary estrone, estradiol-17beta, estriol, pregnanediol and androsterone were identified and measured during 3 menstrual cycles in 2 female orangutans. in 2 of the cycles, the animals excreted 1-8 mug/day estrone, 0.5-6 mug/day estradiol-17beta, 1-8 mug/day estriol, 20-206 mug/day pregnanediol and 120-522 mug/day androsterone during the first half of the menstrual cycle. in the second half of the cycle, corresponding values were 3-21 mug/day estrone, 2-10 mug/day estradiol-17beta, 1-9 mug/day e ...	1975	162882
ulcerative colitis in apes: a comparison with the human disease.	the pathological changes in the colons of two young gorillas and an adult orang-utan which developed diarrhoea and died, are described. since no causative agents could be identified and the changes were indistinguishable from the active phase of ulcerative colitis in humans, these cases were considered examples of this disease in apes. evidence of early healing was found in one case and the suitability of apes and monkeys as possible animal models of the human disease is discussed.	1975	808598
hemispheric differences in the brains of great apes.	asymmetries are found in the cerebral hemispheres of some great apes, particularly in the orangutan, that are similar to those seen in man. studies in the orangutan might be more likely to help in understanding the evolution of handedness or language than studies in chimpanzees.	1975	809093
comparative immunochemical studies of primate hemoglobins.	the antigenic properties of a number of chromatographically purified primate hemoglobins were compared to those of normal human hemoglobin using a sensitive radioimmunochemical procedure. the degree of inhibition of the antigen-antibody reaction with heterologous hemoglobins appeared to be related to the structural similarity of these proteins to the normal human hemoglobin immunogen. with the exception of the baboon hemoglobin, the antigenicity of the hemoglobins paralleled the phylogeny of the ...	1975	812480
dental field theory: an application to primate evolution.	a major complicating factor in using dental data in analyses of taxonomic and evolutionary problems is the existence of morphogenetic fields. efforts are made to abstract tooth crown size morphogenetic fields of the orangutan. the utility of coefficients of variability and factor analysis, to this end, is presented. resulting morphogenetic dental crown size fields are described and related to hominoid dental evolution.	1975	1054346
[comparison of the karyotype of the orangutan (pongo pygmaeus) to those of man, chimpazee, and gorilla].	various banding thechniques were employed to compare the karyotype of the orang-utan (pongo pygmaeus) with those of man, the chimpanzee, and the gorilla. the following was concluded: 1) almost all the bands are common, their analogy being close to 99%. the four species derive, therefore, from a common ancestor. the rearrangements which occurred during evolution were generally balanced; 2) the analysis of rearrangements shows that the orang-utan, then the gorilla, then the chimpanzee, and lastly ...	1975	1080978
[pericentric inversion of no. 3, homozygous and heterozygous, and centromeric transposition of no. 12 in a family of orangutans. implications for evolution].	an orang-utan family is reported in which the father (piku) is homozygous for a pericentric inversion of chromosome 3 and heterozygous for a structural rearrangement of chromosome 12 (author's nomenclature for this species). the latter is interpreted as transposition of the centromere by insertion into band q213 [ins cen(12)(q213)]. piku's mate has a normal female chromosome complement. his daughters by this mate (agnès and ursula) are heterozygous for both his rearrangements. a fifth orang-utan ...	1975	1083190
the relative body weights of bornean and sumatran orangutans.	although original field data suggested that the average bornean orangutan weighed twice as much as the sumatran ones, this is shown to be an error. the only statistically significant difference in weight is between males and females, regardless of geographical area or data source.	1975	1146986
disruption of performance of a lab-born orangutan after introduction of irrelevant foreground cues.	discrimination performance of the three great ape genera has previously been shown to be differentially influenced by the introduction of irrelevant foreground cues, with accuracy of performance of orangutans significantly more disrupted than chimpanzees or gorillas. this disruption may be species-related to how arboreal or terrestrial the subjects would be in their natural habitat. the tendency of the organgutan toward disruption of performance following the introduction of visual foreground cu ...	1975	1178339
karyotype of the gibbons hylobates lar and h. moloch inversion in chromosome 7.	a karyotype of the gibbon, hylobates, has been prepared based on the chromosome banding patterns produced by quinacrine, trypsin-giemsa, and centromeric heterochromatin stains. the banding patterns of h. lar and h. moloch are virtually identical. no brilliant quinacrine-fluorescent areas are present. the banding pattern of most of the gibbon chromosomes show less resemblance to those of the human, chimpanzee, gorilla, or orangutan than the chromosomes of the higher primates do to each other, sug ...	1975	1183241

comparative morphological remarks on the origin of the posterior femoral cutaneous nerve.	the origin and course of the posterior femoral cutaneous nerve were observed macroscopically in 38 japanese adult cadavers which were dissected in the university of hokkaido, faculty of medicine during the years 1971/72 and the results obtained were compared with those from some other mammals (rat, rabbit, dog and cat) and a number of bibliographical findings on the other animals. on the basis of the archetype of the pudendal plexus, the site of origin of the posterior femoral cutaneous nerve w ...	1976	1275304
malaria of the orang-utan (pongo pygmaeus) in borneo.	the primary objective of this project was to study the life cycle and ecology of plasmodium pitheci, a malaria parasite of the orang-utan. the field work was based on the orang-utan rehabilitation centre in the sepilok forest reserve of eastern sabah. two visits were made to sepilok, the first in february and march, 1972, and the second (by w.p.) in january 1974. on the first visit two species of "surrogate host" were taken to sabah, i.e. chimpanzees and aotus monkeys for experimental work. the ...	1976	10589
detection of nucleolus organizer regions in chromosomes of human, chimpanzee, gorilla, orangutan and gibbon.	nucleolus organizer regions were detected by the ag-as silver method in fixed metaphase chromosomes from human and primates. in the human, silver was deposited in the secondary constriction of a maximum of five pairs of acrocentric chromosomes: 13, 14, 15, 21 and 22. the chimpanzee also had five pairs of acrocentric chromosomes stained, corresponding to human numbers 13, 14, 18, 21 and 22. a gibbon had a single pair of chromosomes with a secondary constriction, which corresponded to the nucleolu ...	1976	61844
pregnancy zone protein analogue in pregnant and non-pregnant primates, and its decrease during pregnancy in some monkey species.	rabbit antiserum to human pregnancy zone protein (pzp) cross-reacted with analogous proteins in several species of primates. the chimpanzee pzp showed reactions of identity with human pzp, while the pzp analogue in the orangutan, in four species of old world monkeys (pig-tailed, rhesus, cynomolgus and stump-tailed) and in a species of new world monkey (squirrel) showed equivalent reactions of partial identity with human pzp. in the chimpanzee and orangutan, the pzp analogue was present in low co ...	1976	64329
chromosomal distribution of rdna in pan paniscus, gorilla gorilla beringei, and symphalangus syndactylus: comparison to related primates.	hybridization in situ was used to identify rdna in chromosomes of the pygmy chimpanzee, mountain gorilla, and siamang gibbon. in contrast to other pongids, and man, the gorilla has only two pairs of rdna-containing chromosomes. the single pair in the siamang bears no resemblance to the nucleolar chromosome of the closely related lar gibbon. pan paniscus and p. troglodytes have the same rdna distribution, and similar karyotypes except in the structure of chromosome 23p. grain counts over unbanded ...	1976	1009815
comparison of hemagglutination inhibition pregnancy tests in the chimpanzee and the orangutan.	a hemagglutination inhibition pregnancy test (subhuman primate pregnancy test), based on antiserum to the beta-subunit of ovine luteinizing hormone was evaluated for use in the chimpanzee and orangutan. the test was shown to give earlier indication of pregnancy in both species that two sensitive tests currently available for use in man (the pregnosticon accusphere test and the ucg-test). a comparison of sensitivity to chimpanzee chorionic gonadotropin was performed. the subhuman primate pregnanc ...	1976	1018479
pulmonary alveolar microlithiasis in the orang-utan (pongo pygmaeus).	a 19-years-old male orang-utan had a brief illness of two weeks with marked dyspnoea. necropsy revealed diffuse bilateral pulmonary alveolar microlithiasis. this is the first account of this pathoanatomical entity in lower primates.	1976	1028347
evaluation of the sub-human primate tube test for pregnancy in primates.	a haemagglutination inhibition test, developed specifically for primates, diagnoses early pregnancy in the chimpanzee, gorilla, orang-utan and baboon. the test was sensitive and reacted positively when the concentration of gonadotrophin in urine was equivalent to 0.03 i.u. human chorionic gonadotrophin per ml. this degree of sensitivity and the certitude that it cross-reacts with primate luteinizing hormone probably accounts for most of the false positive results.	1976	819712
a chromosome rearrangement in orangutan studied with q-, c-, and g-banding techniques.	a constitutional chromosome rearrangement is a phenotypically normal male organutan is described. the rearrangement resulted from three breakages in chromosome 9 and involved a pericentric inversion and additional reciprocal transpositions of the terminal segments of both arms. q-, g-, and c-banding studies were carried out, and it was shown that the chromosomes affected was a member of the only pair in the complement that lacked a centromeric c-band and that its g-banding pattern closely resemb ...	1976	820522
primate chorionic gonadotropins: antigenic similarities to the unique carboxyl-terminal peptide of hcgbeta subunit.	antigenic similarities of chorionic gonadotropin from human (hcg), chimpanzee (chcg), gorilla (gcg), orangutan (orcg), baboon (pacg), macaque (mcg), and marmoset (macg) were investigated in a radioimmunoassay system using an antiserum (rabbit h93) with antigenic determinants known to reside in the terminal 15 amino acid residues of the unique carboxyl-terminal peptide of hcgbeta, which makes it highly specific for hcg without crossreactivity to hlh. our findings indicate that the extreme antigen ...	1976	826547
morphological cerebral asymmetries of modern man, fossil man, and nonhuman primate.	cerebral asymmetries are common in modern and fossil man and the great apes. those occurring most often are listed here: 1. the left sylvian fissure in man is longer than the right and in both fetal and adult brains the posterior end of the right sylvian fissure is commonly higher than the left. associated with these findings, the left planum temporale is usually longer than the right. 2. the left occipital pole is often wider and usually protrudes more posteriorly than the right. 3. the left la ...	1976	827951
evolution of type c viral genes: evidence for an asian origin of man.	old world monkeys and apes, including man, possess, as a normal component of their cellular dna, gene sequences (virogenes) related to the rna of a virus isolated from baboons. a comparison of the viral gene sequences and the other cellular sequences distinguishes those old world monkeys and apes that have evolved in africa from those that have evolved in asia. among the apes, only gorilla and chimpanzee seem by these criteria to be african, whereas gibbon, orang-utan and man are identified as a ...	1976	179013
antigens and dna of a chimpanzee agent related to epstein-barr virus.	biological and biochemical studies of the herpesvirus of chimpanzees previously demonstrated to be antigenically related to human epstein-barr virus (ebv) indicated that the agent is similar to ebv in that: (i) leukocyte culture of chimpanzees whose sera contained antibody against ebv capsid antigen could yield long-term lymphoblastoid cell lines (ch-lcl) with b-cell characteristics; (ii) the dna of ch-lcl contained sequences homologous to approximately 35 to 45% of human ebv; (iii) ch-lcl conta ...	1976	184297
pulmonary nocardiosis in an orangutan.	pulmonary nocardiosis was diagnosed in an adult male orangutan (pongo pygmaeus) being maintained in an outdoor facility. periodically, the orangutan had had clinical signs of an upper respiratory tract infection, as evidenced by slight nasal discharge and cough. at the terminal stage, the orangutan had acute respiratory embarrassment, with epistaxis, and died before diagnosis could be made and treatment initiated. gross necropsy findings included fibrosis of the pulmonary parenchyma as well as e ...	1976	789315
fluorescent (f) bodies in the spermatozoa of man and the great apes.	mature spermatozoa of the chimpanzee (pan troglodytes), the gorilla (gorilla gorilla), and the orangutan (pongo pygmaeus) were stained with quinacrine dihydrochloride. fluorescent (f) bodies were visualized in the spermatozoa of the chimpanzee and gorilla but were absent in the orangutan, in which there is no brilliant fluorescence in any chromosome. the f bodies appeared to be randomly located in the sperm heads of these two species, as they usually are in human spermatozoa. however, the propor ...	1976	17494623
a polymorphic structural rearrangement in the chromosomes of two populations of orangutan.	a rearranged chromosome 9 was found in 12 of 23 specimens of orangutan, 4 of bornean and 8 of sumatran origin. nine animals were heterozygous, and 3 were homozygous carriers for the variant chromosome, which was also traced in 4 other animals not studied by us. this type of chromosome rearrangement has been previously described (seuánez et al., 1976) and is probably the same chromosome shown by lucas et al. (1973) and reported by turleau et al. (1975) in other specimens. there is obviously a ver ...	1976	17494624
establishment of a cell line with associated epstein-barr-like virus from a leukemic orangutan.	an epstein-barr virus like herpesvirus has been isolated from a lymphoid cell line derived from an orangutan with spontaneous myelomonocytic leukemia. herpesvirus has not previously been isolated from this species of higher ape.	1977	198878
an investigation of the homology of guanylate kinase isozymes in mammals and further evidence for multiple guk gene loci.	guanylate kinase in the red cells of 63 different mammalian species was studied by electrophoresis and multiple molecular forms of the enzyme were found in all species. two species were investigated in more detail. using molecular weight estimates as a criterion of homology, the fallow deer and the chinese hamster were found to have isozymes that corresponded to isozyme e, f, and g of man. variation in the guanylate kinase isozymes was detected in a small population of orangutans. results sugges ...	1977	201245
pregnancy diagnosis in the orangutan (pongo pygmaeus) using the subhuman primate pregnancy test kit.	a determination was made of the gestational interval over which the subhuman primate pregnancy test, a hemagglutination inhibition test for urinary chorionic gonadotropin, accurately indicated conception and the continuation of pregnancy in an orangutan (pongo pygmaseus). the initial positive diagnostic test response occurred about 8 months before parturition and positive responses continued throughout gestation. a test made one day after parturition was positive indicative of some residual urin ...	1977	850394
the development of the anterior falcate and lacrimal arteries in the human.	certain arteries of the head were studied in injected human fetuses from 143 to 290 mm c.-r., as well as in the orang-utan and gorilla, and in microscopical sections from 29 to 162 mm c.-r., as well as in an adult. it was found that, during human ontogenesis, an anterior falcate artery supplies the dura mater of the medial part of the frontal bone. it appears at 40 mm and reaches its full development by 115 mm. normally it becomes reduced and is transformed into the anterior meningeal artery pos ...	1977	855940
the location of dna homologous to human satellite iii dna in the chromosomes of chimpanzee (pan troglodytes), gorilla (gorilla gorilla) and orang utan (pongo pygmaeus).	radioactive rna with sequences complementary to human dna satellite iii was hybridised in situ to metaphase chromosomes of the chimpanzee (pan troglodytes), the gorilla (gorilla gorilla) and the orangutan (pongo pygmaeus). a quantitative analysis of the radioactivity, and hence of the chromosomal distribution of human dna satellite iii equivalent sequences in the great apes, was undertaken, and the results compared with interspecies chromosome homologies based upon giemsa banding patterns. in so ...	1977	880842
surgical drainage of a submandibular air sac in an orangutan.	continuous enlargement of a submandibular air sac was observed in a 7-year-old female orangutan. the animal was treated with tetracycline orally prior to administering phencyclidine and establishing surgical drainage. the incision into the air sac remained patent for 5 days and the cutaneous wound healed 2 weeks later.	1977	924857

evolution of primate chromosomes.	human and higher primate chromosomes have been compared by general and regional banding methods, including hybridization in situ. the general banding patterns of the chromosomes of gorilla, chimpanzee, and orangutan, but not gibbon, are similar to those of the human. preliminary results show that chromosomes with similar banding patterns in different species often carry the same genes. repetitious dna's have undergone changes in structure and distribution which are reflected in changes in the re ...	1977	929190
the distribution of sequences complementary to human satellite dnas i, ii and iv in the chromosomes of chimpanzee (pan troglodytes), gorilla (gorilla gorilla) and orang utan (pongo pygmaeus).	human satellite dnas i, ii and iv were transcribed to yield radioactive complementary rnas (crnas). these crnas were hybridised to metaphase chromosomes of man, chimpanzee (pan troglodytes), gorilla (gorilla gorilla) and orang utan (pongo pygmaeus). the results of this in situ hybridisation were analysed quantitatively and compared with accepted chromosome homologies based on giemsa banding patterns. the crna to satellite ii (crnaii) did not hybridise to chimpanzee chromosomes, although its hybr ...	1977	561680
sexual behavior of captive orangutans.	opposite-sex pairs of orangutans were tested for sexual behavior during the intermenstrual period of the female. the male orangutan was the primary initiator of sexual interactions and initiated copulation forcefully on a daily basis, irrespective of female resistance. however, although single copulations occurred daily, copulations beyond the first occurred most frequently during midcycle. other evidence of cyclicity in behavior was the midcycle decrease in female avoidance of the male and incr ...	1977	563223

electromyography of pongid shoulder muscles iii. quadrupedal positional behavior.	electromyographic (emg) recordings were taken from 14 shoulder muscles (or major parts of them) in a gorilla, a chimpanzee and an orangutan as they stood quadrupedally and tripedally, descended from elevated substrates, crutch-walked, and progressed quadrupedally on inclined and level substrates. in the african apes, low potentials commonly (but not always) occurred in the sternocostal pectoralis major, anterior deltoid, supraspinatus and subscapularis muscles during quadrupedal stance. the quad ...	1978	677298
activities of pongid thigh muscles during bipedal behavior.	electromyographic recordings were taken from 12 thigh muscles (or major parts of them) in a gorilla, from 6 thigh muscles in a chimpanzee, and from 2 thigh muscles in an orangutan as they engaged in bipedal positional behavior, including stance, reaching overhead, lunging, leaping and walking. in the african apes, symmetric bipedal stances with hindlimb flexure were accompanied by notable emg potentials generally increased to or remained at moderate and high levels. our studies on the gluteal (t ...	1978	736109
endodontic surgery for treatment of a fistulated molar abscess in an orangutan.	an adult bornean orangutan was treated for bacterial labyrinthitis, which was a sequela to a molar abscess and maxillary sinusitis. antibiotic therapy and endodontic surgery led to complete remission of clinical signs.	1978	738934
suppurative arthritis in an infant orangutan.	a 12-day-old male orangutan (pongo pygmaeus) was removed from its mother because of oral ulcers and reluctance to suckle. close examination revealed ulcerations extended to the mandibular bone. staphylococcus aureus was cultured from the oral lesions. despite intensive antibiotic therapy, the infection progressed to septicemia, with suppurative arthritis of the left coxofemoral and right radiohumeral joints. treatment included removal of synovial exudate by aspiration, indwelling drains, and art ...	1978	738935
the v gamma chain of fetal hemoglobin of the orangutan.	previous studies suggested that orangutans have nonallelic structural genes for their gamma chains, because either a threonyl or an alanyl residue may occupy position 135. further investigation has now detected that position 75 may have either an isoleucyl or a valyl residue. from available evidence, the isoleucyl and threonyl residues are in one chain an the valyl and alanyl in the other. orangutans appear to be homozygous for the two types of nonallelic genes.	1978	751647
further characterization of a herpesvirus-positive orang-utan cell line and comparative aspects of in vitro transformation with lymphotropic old world primate herpesviruses.	an orang-utan (pongo pygmaeus) suspension line, cp81, was shown to lack myeloid markers of lysozyme activity an d phagocytosis but to be positive for lymphocytic n-alkaline phosphatase activity, and to release a b-cell-tropic herpesvirus. this herpesvirus, termed herpesvirus pongo, had 30--40% dna homology with ebv and was present at 2-3 genome copies per cp-81 cell. gibbon lymphocytes transformed by h. pongo, epstein-barr virus (ebv), and h. papio (of baboon, papio hamadryas, origin) were found ...	1978	208990
differential inhibitory effects of 5-bromodeoxyuridine on vaccinia and monkeypox viruses.	replication of vaccinia and monkeypox viruses was impeded in the presence of 5-bromodeoxyuridine (budr) in rl-33 cells derived from rabbit lung tissue. the different degree of inhibition was found among strains of those viruses, in which it was evident that five strains (cv-1, lister, ihd, dairen-i and ikeda) of vaccinia viruses resulted in more reduced yields of infectious virus than four strains (sen-19, orang utan, copenhagen and sierra leone) of monkeypox viruses. there was also strain varia ...	1978	212474
in vitro lymphocyte transformation by epstein-barr virus (ebv)-like viruses isolated from old-world non-human primates.	ebv-like viruses and lymphoid cell lines have been isolated from baboons and an orangutan. the cell lines have properties of b- or undifferentiated lymphocytes and have antigens and dna related to those of ebv. the baboon virus has a broad in vitro transformation host range among lymphocytes of old-world simian species whereas the orangutan isolate has a narrower host range. baboon and orangutan viruses as well as ebv have shown transforming activity for gibbon lymphocytes. baboon virus is infec ...	1978	221359

immunological relationships of human and subhuman primate pregnancy-associated plasma proteins.	(1) four pregnancy-associated plasma proteins cross-reactive with antibodies to the human pregnancy proteins were detected in several species of pregnant subhuman primates. in the case of the two apes studied (chimpanzee and orangutan), these appeared to be immunologically identical to the human papps (papp-a, -b, -c, and hcs). in the old world monkeys analyzed, equivalent partially cross-reactive papps were found; while in the new world squirrel monkey, only faint traces of cross-reactive papp- ...	1978	413796

association of antral diaphragms and hypertrophic pyloric stenosis.	in a 2 year period at children's hospital of philadelphia, seven human infants and a baby orangutan all presented with a previously unreported association of a prepyloric membrane and hypertrophic pyloric stenosis. in the humans, the pyloric stenosis was the obstructive lesion, and in the orangutan, the web. we also report a 6-year-old patient with previous pyloromyotomy who presented because of prolonged retention of a marble in the stomach by an associated antral membrane.	1978	97994
orangutan death and scavenging by pigs.	pongid remains are rarely recovered from tropical rain forests. observations of a bornean bearded pig (sus barbatus) scavenging an orangutan (pongo pygmaeus) carcass and the recovery of an orangutan skull fragment corroborates evidence from africa and suggests that the scavenging of wild pigs may play an important role in the destruction of pongid remains.	1978	17847332
cyclic proceptivity in a captive female orang-utan (pongo pygmaeus abelii).	an adult male-female pair of orang-utans was observed for a 3-month period, commencing with the introduction of the animals to each other. after approximately 2 weeks, the female began to show proceptive behaviors towards the male. two other proceptive periods were observed, occuring from 26 to 30 days apart, and lasting for 4-6 days. these female-initiated periods of sexual activity began with increased locomotor activity, solitary play, proximity to the male, following the male, and social gro ...	1979	24896390

primate repetitive dnas: evidence for new satellite dnas and similarities in non-satellite repetitive dna sequence properties.	repetitious dna sequences have been isolated from a number of the primates in in both suborders anthropoidea and prosimii by hydroxy-apatite chromatography at a cot of 10. in addition to finding previously unreported possible at-rich satellite dnas in orangutan, gibbon, rhesus and slow loris a clear similarity to human dna was found in the nonsatellite repetitious dna sequence properties of the primates in the suborder anthropoidea. this is based on the presence of the hydroxyapatitie isolated 1 ...	1979	114378
a case of trisomy 22 in pongo pygmaeus.	a behaviorally and clinically abnormal female orangutan was analyzed cytologically using general banding techniques and by an alkaline silver method for staining nucleolus organizer regions. the karyotype had 49 chromosomes, including an extra chromosome 22 (49,xx + 22). no variant chromosome types or heterozygous structural rearrangements were found. nine of the 14 large acrocentric chromosomes, nos. 11--17, and three of the five presumptive human g-group equivalents, i.e., two of three chromos ...	1979	88305
demonstration of specific heterochromatic segments in the orangutan (pongo pygmaeus) by a distamycin/dapi double staining technique.	orangutan metaphase chromosomes, obtained from a female animal with trisomy 22, were stained by a recently developed distamycin/dapi fluorescent technique which had been shown to differentiate specific c-bands on human chromosomes, as well as by other banding techniques. distamycin/dapi-brilliant fluorescence was observed in the short arm regions of acrocentric chromosomes 11--17, 22 and 23, and a brightly fluorescent paracentromeric band was seen on chromosome 8. a smaller amount of fluorescenc ...	1979	88309
production of antibodies to human immunoglobulins in a gibbon.	immunization of a chimpanzee, a gibbon, a baboon and a rhesus monkey with human globulins gave different results. while chimpanzees did not produce any anti-human antibodies, baboon and rhesus monkey responded by producing anti-human igg antibodies that did not show subclass or allotype specificity. in the gibbon antiserum, on the other hand, six different antibodies were demonstrated with a specificity against one or more of the four human igg subclasses, including one allotype. comparative inv ...	1979	93346

comparative and functional morphology of hominoid fingers.	comparisons of hominoid metacarpals and phalanges reveal differences, many of which are closely linked to locomotor hand postures. the african apes display features of the metacarpals and phalanges which distinguish them from the other hominoidea. these features are most evident in digits iii and iv. the orangutan hand is demonstrably less well adapted to knuckle-walking and is distinctive in its adaptation to power and hook grasping of vertical and horizontal supports, respectively. orangutan f ...	1979	443358
