| lactate-transport activity in rbcs of trained and untrained individuals from four racing species. | in red blood cells (rbc) of horses, both lactate-transport activity and lactate accumulation during races vary interindividually. to study whether similar variation in lactate transport is apparent also in rbcs of other racing species, blood samples were collected from 21 reindeer, 40 horses, 31 humans, and 38 dogs. total lactate-transport activity was measured at 10 and 30 mm concentrations, and the roles of the monocarboxylate-transporter (mct) and the inorganic anion-exchange transporter (ban ... | 2001 | 11404274 |
| muscle fibre growth in undernourished reindeer calves (rangifer tarandus tarandus l.) during winter. | to study whether moderate under-nutrition causes muscle wasting, reindeer (rangifer tarandus tarandus l.) calves were fed either pelleted reindeer feed ad libitum (n=8) or restricted amounts of lichens (n=8). the restricted amount was 60% of ad libitum intake of lichens, and the feeding period was 6 weeks preceded by a 2-week adjustment period. biopsy samples from the middle gluteal muscle (m. gluteus medius) for the analysis of fibre composition and area, as well as for the activity of cathepsi ... | 2001 | 11423319 |
| contrasting regulation of fecundity in two abomasal nematodes of svalbard reindeer (rangifer tarandus platyrhynchus). | stability of trichostrogylid populations indicates that some form of density-dependent regulation occurs which could act through fecundity. we present evidence for intraspecific density-dependent effects in 1 of 2, dominant, abomasal nematodes species (ostertagia gruehneri) of svalbard reindeer (rangifer tarandus platyrhynchus). we found evidence in o. gruehneri, for density-dependent regulation of female worm length in april, july and october 1999. however, it is only in july that female worm l ... | 2001 | 11444620 |
| hearing in reindeer (rangifer tarandus). | the audiogram of two yearling male reindeer (rangifer tarandus tarandus) were determined using a conditioned suppression/avoidance procedure. during testing, the animal was drinking from a metal bowl while pure tone signals were played at random intervals and followed by an electric shock in the bowl. by breaking contact with the bowl at sound signals, the animal avoided the shock. the animals detected sounds at intensities of 60 db or less from 70 hz to 38 khz. the frequency range of best sensi ... | 2001 | 11467499 |
| cadmium in caribou (rangifer tarandus) kidneys: speciation, effects of preparation and toxicokinetics. | caribou kidney is a major source of cadmium (cd) in the traditional diets of many aboriginal communities in the arctic. in order to characterize the risk of cd exposure, we studied the speciation of cd in caribou kidneys and how, it can be affected by food preparation. cd in caribou kidneys was bound to metallothionein (mt) (40%) high molecular weight proteins (50-500 kda) (30%) and existed as free ions (10%). there was no change in cd concentrations after the samples were baked at 350 degrees c ... | 2001 | 11469316 |
| evidence for the presence of two novel pestivirus species. | the genus pestivirus of the family flaviviridae comprises four species, namely bovine viral diarrhea virus-1 (bvdv-1), bvdv-2, border disease virus (bdv), and classical swine fever virus (csfv). comparative analyses of partial sequences have suggested that pestivirus isolates from giraffe (giraffe-1) and reindeer (reindeer-1) are distinct from the established species (becher et al., virology 262, 64--71, 1999). in this study, we report the complete genomic sequences of pestivirus strains giraffe ... | 2001 | 11485413 |
| traditional foods in the diet of chukotka natives. | during several medical expeditions the recipes and technology of traditional foods of the indigenous population of chukotka have been collected. traditional foods are important sources of fat, protein and essential nutrients. the traditional diet of chukotka natives consists of caribou meat, marine animals and fish, depending on the place of residence. all meat products or fish are eaten with local plants: roots, green leaves, berries or seaweed. local foods are usually eaten raw frozen and dipp ... | 2001 | 11507962 |
| basal metabolic adaptation of the evenki reindeer herders of central siberia. | previous research has suggested that basal metabolic rates (bmrs of indigenous circumpolar populations are elevated, perhaps as an adaptation to chronic, severe cold stress. this study examines variation in bmr among indigenous (evenki) and nonindigenous (russian immigrant) populations living in central siberia to determine: 1) whether the evenki show evidence of increased metabolic rates, and 2) whether the metabolic responses of the evenki are different from those of the recent russian migrant ... | 2000 | 11534006 |
| seasonal and long-term variations in 137cs among adults from swedish hunter families. | to study seasonal variations in 137cs, whole-body content measurements of adults from swedish hunter families have been performed in autumn 1997 and spring 1998. measurements were performed in three locations, by, harbo and gävle, geographically close (within 100 km of each other) but with large differences in ground deposition levels. the hunter families at these three locations were previously measured in 1994. the measured persons were also asked for their frequency of intake of moose, roe-de ... | 2001 | 11548326 |
| the marking of livestock in traditional pastoral societies. | the marking of animals has been practised in all pastoral systems since time immemorial. using a series of examples representative of the major pastoral civilisations of the world, the author presents the techniques used (branding and ear incisions, either separately or in combination). in the light of the characteristics common to pastoral societies, the following points are analysed: a) the manner in which the marks used by these societies have been conserved or modified in the course of verti ... | 2001 | 11548519 |
| dna evidence that marshallagia marshalli ransom, 1907 and m. occidentalis ransom, 1907 (nematoda: ostertagiinae) from svalbard reindeer are conspecific. | the gastro-intestinal parasitic nematodes of ruminants marshallagia marshalli and m. occidentalis are morphs of a single species according to indirect evidence. in this study, their taxonomic status and molecular identification were assessed more directly in isolates from the abomasal nematode community of svalbard reindeer using genetic data. dna sequences of the first and second internal transcribed spacers of nuclear ribosomal rna genes were obtained from individual nematodes by the polymeras ... | 2001 | 11586078 |

| effect of origin of radiocaesium on the transfer from fallout to reindeer meat. | data on radiocaesium contamination of reindeer from five regions in sweden have been used, together with interpolated radiocaesium deposition data, to quantify spatial variation in transfer to reindeer meat and to consider how it changes with time in different areas. since the regions were contaminated to different extents by global and chernobyl fallout, it was also possible to determine the influence of the origin or age of radiocaesium fallout on the transfer to reindeer meat. the regions dif ... | 2001 | 11669265 |
| plasma urea, creatinine, and urea: creatinine ratio in reindeer (rangifer tarandus tarandus) and in svalbard reindeer (rangifer tarandus platyrhynchus) during defined feeding conditions and in the field. | variation in plasma urea and creatinine concentration and plasma urea:creatinine ratio (u:c) were studied in semidomestic free-ranging reindeer (rangifer tarandus tarandus) on the norwegian mainland, in wild svalbard reindeer (rangifer tarandus platyrhynchus), and in captive reindeer maintained either on a lichen-based diet or a protein-rich concentrate to investigate whether these parameters could be used as indicators of the nutritional status of reindeer. in the mainland animals, plasma creat ... | 2001 | 11731982 |
| bone morphogenetic protein 3b expressing reindeer antler. | a cdna sequence of bone morphogenetic protein 3b (bmp-3b) of reindeer antler was produced with degenerative homology primers in polymerase chain reaction (pcr). an in situ hybridization study of bmp-3b mrna in 1-month-old antler showed expression in most differentiated cells in the antler center. in addition, the bone-inductive capacity of the reindeer antler matrix was evaluated. decalcified and powdered antler matrix of different stages of antler maturity was implanted in gelatin capsules unde ... | 2002 | 11745540 |
| [retrospective estimate of the individual history of life in population studies on mammals]. | analysis of the recording structures in mammals, such as dentine, cementum, or bone tissue, makes it possible to estimate the parameters of individual history of life: age at the moment of death, seasons of death and birth, growth rate, age of sexual maturation, etc. using the reindeer (rangifer tarandus) as an example, it has been shown what specific life features essential for population studies may be estimated when only mandibles with teeth are available. | 2001 | 11785257 |
| human absorption and retention of polonium-210 from caribou meat. | the gastrointestinal (gi) absorption factors and the biological retention times for polonium were determined for a group of 14 volunteers--seven men and seven women--from saskatoon, saskatchewan, canada. each volunteer consumed 2.0 kg of caribou meat containing known amounts of naturally occurring 210po. urine and faecal samples were collected for up to 65 days after meat consumption and analysed for 210po. the average gi absorption factor for the 14 volunteers was 56 +/- 4% (range = 31-71%), no ... | 2001 | 11843339 |
| effect of antiandrogen cyproterone acetate on the development of the antler cycle in southern pudu (pudu puda). | the antler cycle of pudu is similar to other cervids, but unlike most boreal deer, male southern pudu (pudu puda) exhibits two seasonal peaks of lh and testosterone. in that respect, pudu is similar to roe deer. whereas the antler cycle in some deer species, such as roe deer or white-tailed deer, is very sensitive to variation of testosterone, in other cervids, such as fallow deer or reindeer, a blockade of androgens with cyproterone acetate (ca) has little or no effect on the timing of the antl ... | 2002 | 11857473 |
| prey specialization may influence patterns of gene flow in wolves of the canadian northwest. | this study characterizes population genetic structure among grey wolves (canis lupus) in northwestern canada, and discusses potential physical and biological determinants of this structure. four hundred and ninety-one grey wolves, from nine regions in the yukon, northwest territories and british columbia, were genotyped using nine microsatellite loci. results indicate that wolf gene flow is reduced significantly across the mackenzie river, most likely due to the north-south migration patterns of ... | 2001 | 11903892 |
