Comparison of Spring Migration Ecology of American Black Ducks (Anas rubripes) and Mallards (Anas platyrhynchos) in the Montezuma Wetlands Complex

I compared behavior, habitat selection, and movements between American black ducks and mallards using the Montezuma Wetlands Complex (MWC) during spring. I did not detect differences in behavior between species within habitat types. Black ducks used open water more than mallards. Black ducks chose home ranges with less agriculture, developed, and forested wetland cover types and greater emergent marsh and open water relative to their availability within the MWC, but used cover types in proportion to their availability within their home ranges. Mallards chose home ranges with cover types proportional to their availability within the MWC and used cover types in proportion to their availability within home ranges. Local movement step lengths were similar between species at 0.5 – 25 km. Departure date was earlier with increasing percent use of agricultural areas in spring, a possible explanation for mallards departing the MWC earlier than black ducks in 2016

Gaston’s Economic, Religious and Political Intersectionality

Gaston county, North Carolina provides a perfect case to explore the intersectionality of the economy, politics, and religion that dominates power structures on a national scale. With an attention to the Loray Mill strike of 1929, this paper theologically analyzes the relationship between neoliberal economy and the prosperity gospel and questions whether the church is a setting of concessions when it should be acting as a voice for its constituents, regardless of what the upper class desires or has constructed

Soy isoflavones avert chronic inflammation-induced bone loss and vascular disease

<p>Abstract</p> <p>Background</p> <p>Evidence from epidemiological, clinical and animal studies suggests a link may exist between low bone density and cardiovascular disease, with inflammatory mediators implicated in the pathophysiology of both conditions. This project examined whether supplementation with soy isoflavones (IF), shown to have anti-inflammatory properties, could prevent tissue expression of TNF-α and the development of skeletal pathology in an animal model of chronic inflammation.</p> <p>Methods</p> <p>Eight-week old, intact, female C57BL/6J mice were used. In Phase 1, a lipopolysaccharide (LPS)-dose response study (0, 0.133, 1.33 and 13.3 μg/d) was conducted to determine the LPS dose to use in Phase 2. The results indicated the 1.33 μg LPS/d dose produced the greatest decrease in lymphocytes and increase in neutrophils. Subsequently, in Phase 2, mice were randomly assigned to one of six groups (n = 12–13 per group): 0 or 1.33 μg LPS/d (placebo or LPS) in combination with 0, 126 or 504 mg aglycone equivalents of soy IF/kg diet (Control, Low or High dose IF). Mice were fed IF beginning 2 wks prior to the 30-d LPS study period.</p> <p>Results</p> <p>At the end of the study, no differences were detected in final body weights or uterine weights. In terms of trabecular bone microarchitecture, μCT analyses of the distal femur metaphysis indicated that LPS significantly decreased trabecular bone volume (BV/TV) and number (TbN), and increased separation (TbSp). Trabecular bone strength (i.e. total force) and stiffness were also compromised in response to LPS. The High IF dose provided protection against these detrimental effects on microarchitecture, but not biomechanical properties. No alterations in trabecular thickness (TbTh), or cortical bone parameters were observed in response to the LPS or IF. Immunohistomchemical staining showed that tumor necrosis factor (TNF)-α was up-regulated by LPS in the endothelium of small myocardial arteries and arterioles as well as the tibial metaphysis and down-regulated by IF.</p> <p>Conclusion</p> <p>These results suggest IF may attenuate the negative effects of chronic inflammation on bone and cardiovascular health. Additional research is warranted to examine the anti-inflammatory properties of the soy isoflavones and the mechanisms underlying their prevention of chronic inflammation-induced bone loss.</p

The diet of young Neandertals from France, Pech de l’Azé I and Hortus II, reconstructed using dental microwear texture analysis

Les adultes néandertaliens présentent des différences de régime alimentaire en fonction de leur paléohabitat. Nous examinons si les jeunes enfants néandertaliens de France datant du stade isotopique marins 3 montrent également ces distinctions alimentaires à partir de l’étude de la texture des micro-usures dentaires des deuxièmes molaires déciduales des individus Pech de l’Azé I, datant d’une phase froide-tempérée, et Hortus II, datant d’une phase froid-aride extrême. L’échantillon comparatif (n=76) comprend des molaires déciduales d’agriculteurs-cueilleurs provenant de trois grottes néolithiques de Belgique, dont Caverne de la Cave à Maurenne (n=5), Sclaigneaux (n=7) et Bois Madame (n=6), ainsi que des agriculteurs de l’époque romaine d’Herculanum (n=15) et médiévaux de Canterbury, Angleterre (n=43). Lorsque la complexité est comparée à l’anisotropie, Pech de l’Azé I présente une valeur élevée provenant de la mastication de plantes à parties dures ou de particules adhérentes, ou de la consommation d’aliments mal transformés ou chargés de silicates abrasifs. En revanche, Hortus II a une valeur faible, peut-être en raison de l’accès limité aux parties dures des plantes comme les graines et les noix. Toutefois, Pech de l’Azé I et Hortus II se ressemblent en présentant une faible valeur d’anisotropie qui est révélatrice de mouvements complexes des mâchoires lors de la mastication et sont différents des enfants humains néolithiques, romains et médiévaux qui ont tendance à avoir des valeurs plus élevées. Les régimes alimentaires des enfants néandertaliens diffèrent en fonction du paléohabitat et sont généralement plus diversifiés que ceux des producteurs d’aliments, qu’ils habitent des environnements boisés ou ouverts.Neandertal adults show differences in diet with respect to paleohabitat. To examine whether Neandertal children of France during Marine Isotope Stage 3 also show these dietary distinctions, the deciduous second molars of Pech de l’Azé I, from a cold-temperate period, and Hortus II from Sub-Phase Vb, an extreme cold-arid interval, were examined using dental microwear texture analysis. The comparative sample (n=76) includes deciduous molars from Neolithic forager-farmers of Belgium, including Caverne de la Cave at Maurenne (n=5), Sclaigneaux (n=7) and Bois Madame (n=6), Roman-era farmers from Herculaneum (n=15) and Medieval agriculturalists from Canterbury, England (n=43). When complexity is compared to anisotropy, Pech de l’Azé I exhibits an elevated value from the mastication of plants with hard parts or adherent particles, or the consumption of foods that were poorly processed or grit-laden, whereas Hortus II presents a low value, perhaps from limited access to hard plant parts such as seeds and nuts. However, Pech de l’Azé I and Hortus II resemble each other in having a low value for anisotropy, which is indicative of complicated movements of the jaws during mastication and are dissimilar to Neolithic, Roman and Medieval human children who tend to have higher values. The diets of Neandertal children differ with respect to paleohabitat and typically were more diverse than those of food producers regardless of whether they inhabited wooded or open environments

Stingless bee honey protects against lipopolysaccharide induced-chronic subclinical systemic inflammation and oxidative stress by modulating Nrf2, NF-κB and p38 MAPK

Background: Epidemiological and experimental studies have extensively indicated that chronic subclinical systemic inflammation (CSSI) and oxidative stress are risk factors for several chronic diseases, including cancer, arthritis, type 2 diabetes, and cardiovascular and neurodegenerative diseases. This study examined the protective effect of stingless bee honey (SBH) supplementation against lipopolysaccharide (LPS)-induced CSSI, pointing to the possible involvement of NF-κB, p38 MAPK and Nrf2 signaling. Methods: CSSI was induced in male Sprague Dawley rats by intraperitoneal injection of LPS three times per week for 28 days, and SBH (4.6 and 9.3 g/kg/day) was supplemented for 30 days. Results: LPS-induced rats showed significant leukocytosis, and elevated serum levels of CRP, TNF-α, IL-1β, IL-6, IL-8, MCP-1, malondialdehyde (MDA) and 8-hydroxy-2′-deoxyguanosine (8-OHdG), accompanied with diminished antioxidants. Treatment with SBH significantly ameliorated inflammatory markers, MDA and 8-OHdG, and enhanced antioxidants in LPS-induced rats. In addition, SBH decreased NF-κB p65 and p38 MAPK, and increased Nrf2 expression in the liver, kidney, heart and lung of LPS-induced rats. Furthermore, SBH prevented LPS-induced histological and functional alterations in the liver, kidney, heart and lung of rats. Conclusion: SBH has a substantial protective role against LPS-induced CSSI in rats mediated via amelioration of inflammation, oxidative stress and NF-κB, p38 MAPK and Nrf2 signaling
