We assessed the influence of human leukocyte antigen (HLA) alleles HLA-Bw4 and HLA-Bw6 on CD4 T cell recovery after starting successful combination antiretroviral therapy in 265 individuals. The median gains in the CD4 T cell count after 4 years were 258 cells/microL for HLA-Bw4 homozygotes, 321 cells/microL for HLA-Bw4/Bw6 heterozygotes, and 363 cells/microL for HLA-Bw6 homozygotes (P = .01, compared with HLA-Bw4 homozygotes). HLA-Bw4 homozygosity appears to predict an impaired CD4 T cell recovery after initiation of combination antiretroviral therapy.

Following field observations of wild Agassiz's desert tortoises (Gopherus agassizii) with oral lesions similar to those seen in captive tortoises with herpesvirus infection, we measured the prevalence of antibodies to Testudinid herpesvirus (TeHV) 3 in wild populations of desert tortoises in California. The survey revealed 30.9% antibody prevalence. In 2009 and 2010, two wild adult male desert tortoises, with gross lesions consistent with trauma and puncture wounds, respectively, were necropsied. Tortoise 1 was from the central Mojave Desert and tortoise 2 was from the northeastern Mojave Desert. We extracted DNA from the tongue of tortoise 1 and from the tongue and nasal mucosa of tortoise 2. Sequencing of polymerase chain reaction products of the herpesviral DNA-dependent DNA polymerase gene and the UL39 gene respectively showed 100% nucleotide identity with TeHV2, which was previously detected in an ill captive desert tortoise in California. Although several cases of herpesvirus infection have been described in captive desert tortoises, our findings represent the first conclusive molecular evidence of TeHV2 infection in wild desert tortoises. The serologic findings support cross-reactivity between TeHV2 and TeHV3. Further studies to determine the ecology, prevalence, and clinical significance of this virus in tortoise populations are needed.

Con este trabajo sobre la nobleza de la ciudad de Quito, Christian Büschges amplía el campo de los estudios socio-económicos y políticos sobre las así llamadas élites coloniales, con un análisis que se enfoca de manera especial en las mentalidades y representaciones estamentales, que tan fuertemente marcaron las relaciones sociales del antiguo régimen colonial.

In international law the internment of civilians has only been regulated in writing in the context of the 4th Geneva Convention of 1949. Nevertheless this did not mean that civilians were not protected by at least some rules of customary international law before that date and especially in World War I. Furthermore specialists of international law expected states – at least those considered to be part of the community of civilized nations – to continue to treat all men equal before the law even in wartime. As research already conducted (Bird, Panayi, Fischer) has shown, this was not the case during World War I. Based on these findings the presentation proposed here wants to look into the development of international law and into some national preparations for treating so called “enemy aliens” in the period before 1914 (Austria-Hungary, Australia, United Kingdom), in order to see to what extent principles of international law protecting civilians from the consequences of war can be detected in the pre-war preparations. As far as can be judged so far the issue of loyalty was central in this context. Looking at the war itself, the presentation proposed here will try to look at how far the principles of international law alluded to above continued to influence the policies on “enemy aliens” in the countries mentioned and to see, how the International Committee of the Red Cross tried to use them to legitimize and expand its protective policies in regard to civilians interned in belligerent as well as neutral countries throughout the war.
