The first systematic effort to document traditional ecological knowledge (TEK) of beluga whales (Delphinapterus leucas) in Russia was conducted in the villages of Sireniki, Novoe Chaplino, ...Yanrakinnot, and Uelen, in the Chukotka Autonomous Okrug. The findings describe migratory and local movements, feeding, calving, ecological interactions, and human influences on distribution and behavior. The results add considerable detail to published accounts of belugas in Russian waters of the Bering and Chukchi Seas. Among these are descriptions of avoidance and habituation responses to anthropogenic noise, which appear to depend in part on association with hunting activities. The authors observe that most of the TEK documented in this study came from older hunters, and that the collective pool of traditional knowledge in the region is disappearing. /// La première tentative systématique en vue de documenter le savoir écologique traditionnel (SET) sur les bélougas (Delphinapterus leucas) en Russie a été menée dans les villages de Sireniki, de Novoe Chaplino, de Yanrakinnot et de Uelen, dans l'arrondissement autonome des Tchouktches. Les résultats décrivent les déplacements migratoires et locaux, la nutrition, la mise bas, les interactions écologiques et les influences humaines sur la distribution et le comportement. Les résultats apportent de nombreux détails aux relevés de bélougas dans les eaux russes de la mer de Bering et de la mer des Tchouktches. Ces nouveaux détails incluent la description des réactions d'évitement et d'accoutumance au bruit anthropique, qui semble dépendre en partie de l'association avec les activités cynégétiques. Les auteurs observent que la plupart du SET documenté dans cette étude vient de vieux chasseurs et que le bassin collectif du savoir traditionnel dans la région est en train de disparaître.

Effective ecological monitoring is central to the sustainability of subsistence resources of indigenous communities. For caribou, Arctic indigenous people's most important terrestrial subsistence ...resource, body condition is a useful measure because it integrates many ecological factors that influence caribou productivity and is recognized by biologists and hunters as meaningful. We draw on experience working with indigenous communities to develop a body condition monitoring protocol for harvested animals. Local indigenous knowledge provides a broad set of caribou health indicators and explanations of how environmental conditions may affect body condition. Scientific research on caribou body condition provides a basis to develop a simple dichotomous key that includes back fat, intestinal fat, kidney fat and marrow¬fat, as measures of body fat, which in autumn to early winter correlates with the likelihood of pregnancy. The dichotomous key was formulated on "expert knowledge" and validated against field estimates of body composition. We compare local indigenous knowledge indicators with hunter documented data based on the dichotomous key. The potential con¬tribution of community body condition monitoring can be realized through the continued comparative analysis of datasets. Better communication among hunters and scientists, and refinement of data collection and analysis methods are recommended. Results suggest that specific local knowledge may become generalized and integrated between regions if the dichotomous key is used as a generalized (semi-quantitative) index and complemented with other science and community-based assessments.
OBJECTIVEThe activation of protein tyrosine kinases (PTKs) has been postulated to be involved in cell differentiation and proliferation. To elucidate the involvement of tyrosine kinase genes in ...normal and pathological conditions, we analysed the expression patterns of receptor-type PTKs in the normal and hypertensive hypertrophied heart in rats.
MATERIALS AND METHODSHypertrophied and normal rat hearts were obtained from hypertensive rats; deoxycorticosterone acetate (DOCA)-salt and 2 kidney-1 clip (2K-1C), and their sham-operated rats, respectively. A reverse transcription-polymerase chain reaction (RT-PCR) was performed using degenerated primers which were designed from highly conserved regions in the catalytic domains of receptor-type PTKs. The PCR products were ligated into a sequence vector, and subcloned by transforming bacteria. To compare the expression level of these PTK mRNAs in the normal and hypertrophied heart, we performed semi-competetive RT-PCR and immunohistochemical and Western blot analyses.
RESULTSNucleotide sequencing of approximately 80 clones of PTKs revealed 10 receptor-type, five nonreceptor-type and two unknown types in the rat heart. Tie-2/Tek, Ryk, insulin-like growth factor-I receptor were abundantly expressed in the rat heart as members of receptor-type PTKs. Immunohistochemistry and RT-PCR demonstrated the presence of platelet-derived growth factor (PDGF)-α receptor, PDGF-β receptor and fibroblast growth factor-3 receptor in both normal and hypertrophied hearts. We also confirmed the presence of Flt-1, KDR/Flk-1, and their ligand vascular endothelial growth factor, c-Met and its ligand hepatocyte growth factor (HGF), and Tie-1, Tie-2/Tek by immunohistochemistry and RT-PCR. The co-expression of cardiac HGF and c-Met in hypertrophied hearts, especially in 2K-1C rats, was induced more intensively than that in DOCA-salt rats.
CONCLUSIONThese findings suggest that HGF/c-Met interactions may play an important role in cardiac hypertrophy and remodeling, probably as a result of the activation of the local renin-angiotensin system.
Selective targeting of tumour-endothelium has been proposed as a means of therapy. The successful exploitation of this approach will rely on the identification of suitable targets expressed ...specifically on the tumour-associated endothelium. In an attempt to identify novel tumour-endothelium associated targets we have used differential mRNA display to identify genes up-regulated in an in vitro breast tumour-endothelial cell culture model. Confluent monolayers of human mammary microvessel endothelial cells (HuMMEC) were incubated for 5 days with MDA-MB-231 breast adenocarcinoma cell-conditioned medium (TCM). mRNAs isolated from TCM-treated and control cells were amplified using 104 combinations of four 3(') anchored T(12)VN primers and 26 'random' 10mers by RT-PCR and the products examined on DNA sequencing gels. Seventy-four sequences were cloned and the differential expression of five genes was confirmed using dot-blots. These were identified as procollagen type-IV, Tie-2/Tek receptor tyrosine kinase, NADH dehydrogenase subunit-6, and ferritin heavy-chain, which were up-regulated, and insulin-like growth factor binding protein-5, which was down-regulated. Increased endothelial expression of basement membrane proteins and tyrosine kinase receptors is known to occur during angiogenesis. Our data support the use of this model for further in vitro investigation of tumour angiogenesis.
