Chan An Ancient Maya Farming Community
No full textThe farming community of Chan thrived for over twenty centuries, surpassing the longevity of many larger Maya urban centers. Between 800 BC and 1200 AD it was a major food production center, and this collection of essays reveals the important role played by Maya farmers in the development of ancient Maya society. Chan offers a synthesis of compelling and groundbreaking discoveries gathered over ten years of research at this one archaeological site in Belize. The contributors develop three central themes, which structure the book. They examine how sustainable farming practices maintained the surrounding forest, allowing the community to exist for two millennia. They trace the origins of elite Maya state religion to the complex religious belief system developed in small communities such as Chan. Finally, they describe how the group-focused political strategies employed by local leaders differed from the highly hierarchical strategies of the Classic Maya kings in their large cities. In breadth, methodology, and findings, this volume scales new heights in the study of Maya society and culture.Cover -- Title -- Copyright -- Contents -- List of Figures -- List of Tables -- Foreword -- Acknowledgments -- 1.

COMPOSICIÓN ORNITOLÓGICA DEL COMPLEJO ARQUEOLÓGICO CHAN CHAN, TRUJILLO - 2015
No full textThe great diversity of birds that nowadays exist on the Peruvian’s coasts are big, for this reason the archeological site named Chan Chan presents a widespread fauna’s variety. This work had had like an objective define the birds’ diversity, on the archeological site of Chan Chan of the region La Libertad, province of Trujillo, during the months of July to November of 2015. The determination ornithological has been realized through monthly visits during 6 months; for which the archeological site was divided in five habitats: Bosque seco, Humedal, Litoral, Zona agrícola y Zona arqueológica. The data was registred in fields carts. To determine this study’s were used the index of Shannon–Wiener, Simpson and Equidad; There were define a quantity of 47 species of birds, included in 13 orders, 28 families and 45 genres.The families with the biggest number of species was COLUMBIDAE (4) and EMBERIZIDAE(4). It has obtained a richness species of 47, presenting an high variety of species (index H’ de Shannon-Wiener) of H’= 3,08 bits/individuals. The value index of Simpson (S = 0,93) and Equidad (E = 0,775 H/Hmax) (Martín, 2006). Between the most abundant species were found Columbina cruziana, Pygochelidon cyanoleuca and the species more common were Zenaida meloda, Leptotilaverreauxy, Forpuscoelestis, Pyrocephalusrubinusy Mimuslongicaudatus.La gran diversidad de aves presentes en la costa peruana es alta, por lo que el complejo arqueológico de Chan Chan, presenta una gran diversidad faunística.

Novel gadolinium(III) polyaminocarboxylate macrocyclic complexes as potential magnetic resonance imaging contrast agents
No full textTwo novel Gd(III) complexes with functionalised polyaminocarboxylate macrocycles, 1,4,7-tris(carboxymethyl)-9,24-dioxo-14,19-dioxa-1,4,7,10,23- pentaazacyclododecane (L 1) and 1,4,7-tris(carboxymethyl)-9,25-dioxo- 14,17,20-trioxa-1,4,7,10,23- pentaazacyclotridecane (L 2), were prepared in good yield. Their potential use as magnetic resonance imaging (MRI) contrast agents (CAs) was evaluated by investigating their relaxation behaviour as a function of pH, temperature and magnetic field strength. The 1/T 1 proton relaxivities at 20 MHz and 25°C of GdL 1 (5.87 mM -1 s -1) and GdL 2 (6.14 mM -1 s -1) were found to be significantly higher than the clinically used Gd 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (Gd(DOTA) -) and Gd diethylenetriaminepentaethanoic acid (Gd(DTPA) 2-). The complexes possess one water molecule in the inner coordination sphere whose mean residence lifetime was estimated to be 1.1 and 1.5 μs at 25°C by variable temperature (VT) 17O NMR spectroscopy. © 2004 Elsevier Inc.

Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
Full text linkIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
