A new approach to inventory Diptera species in tropical habitats is described. A 150 x 266 m patch of cloud forest at Zurquí de Moravia, Costa Rica (10.047N, 84.008W) at 1585 meters asl was sampled with two Malaise traps for slightly more than one year (Sept. 12, 2012–Oct. 18, 2013). Further concomitant sampling with a variety of trapping methods for three days every month and collecting during a one-week intensive "Diptera Blitz", with 19 collaborators collecting on-site, provided diverse additional samples used in the inventory. Two other Costa Rican sites at Tapantí National Park (9.720N, 83.774W, 1600 m) and Las Alturas (8.951N, 82.834W, 1540 m), 40 and 180 km southeast from Zurquí de Moravia, respectively, were each sampled with a single Malaise trap to allow for beta-diversity assessments. Tapantí National Park was sampled from Oct. 28, 2012–Oct. 13, 2013 and Las Alturas from Oct. 13, 2012–Oct. 13, 2013. A worldwide group of 54 expert systematists are identifying to species level all 72 dipteran families present in the trap samples. Five local technicians sampled and prepared material to the highest curatorial standards, ensuring that collaborator efforts were focused on species identification. This project, currently in its final, third year of operation (to end Sept. 1, 2015), has already recorded 2,348 species and with many more yet expected. Unlike previous All Taxon Biodiversity Inventories, this project has attainable goals and will provide the first complete estimate of species richness for one of the four megadiverse insect orders in a tropical region. Considering that this is the first complete survey of one of the largest orders of insects within any tropical region of the planet, there is clearly great need for a consistent and feasible protocol for sampling the smaller but markedly more diverse smaller insects in such ecosystems. By weight of their species diversity and remarkable divergence of habit, the Diptera are an excellent model to gauge microhabitat diversity within such systems. Our model appears to be the first to provide a protocol that can realistically be expected to provide a portrayal of the true species diversity of a megadiverse order of insects in the tropics.

Embora a Transi??o Menopausal e a menopausa sejam eventos biol?gicos normais, podem ser acompanhadas de agravos que aumentam o risco de morbidade e mortalidade com destaque para os sintomas agudos da S?ndrome Climat?rica(SC). O tratamento visa o controle destes sintomas para evitar as consequ?ncias tardias da defici?ncia estrog?nica, sempre considerando a seguran?a e a tolerabilidade ao f?rmaco empregado e os fatores de risco para complica??es futuras. Objetivo: Avaliar a efic?cia, o perfil de seguran?a e tolerabilidade do uso da tibolona na transi??o menopausal. Material e m?todos: Estudo randomizado, duplo-cego, controlado com placebo, envolvendo 65 mulheres saud?veis com idade m?dia de 48,5(?3.5) anos. Crit?rios de Inclus?o: a) idade entre 40 e 55 anos; b) ?tero sem anormalidades avaliado por ultrassonografia transvaginal e com espessura endometrial≤10 mm; c) irregularidade menstrual nos ?ltimos 6 meses e amenorreia inferior a 12 meses; d) n?veis s?ricos de Horm?nio Fol?culo Estimulante(FSH)>30mIU/ml; e) SC avaliada pelo ?ndice Menopausal de Blatt e Kupperman (IMK) com escore de pontos>14; f) ?ndice de Massa Corporal<30Kg/m2; g) mamografia com BI-RADS igual a 1 e 2; e ) valores de bioqu?mica sangu?nea, p?s jejum de 12 horas, dentro dos limites de normalidade. Crit?rios de exclus?o: a) fumo; b) uso nos 90 dias que antecederam a entrada no estudo de qualquer medica??o hormonal, psicotr?pica ou que interfiram com metabolismo glic?dico e lip?dico; c) qualquer doen?a neopl?sica anterior ou atual; d) hipertens?o arterial(press?o sist?lica≥160 mmHg e diast?lica≥105 mmHg); e) doen?as hep?ticas e renais; f)desordens cerebrovasculares, tireoideanas, cardiovasculares e 1-xiv tromboemb?licas; g) doen?as mentais; e h) diabetes mellitus. Trinta participantes foram escolhidas pelo m?todo rand?mico para o Grupo Tibolona (GT) que recebeu 2,5 mg/dia de tibolona por via oral durante 12 semanas cont?nuas; as demais 35 foram inclu?das no Grupo Placebo (GP) que recebeu 1 c?psula/lactose/dia, por igual per?odo. Medidas utilizadas: A efic?cia da tibolona foi avaliada pelo IMK e a Escala Climat?rica de Greene (GSC). Na avalia??o da seguran?a e tolerabilidade utilizou-se par?metros bioqu?micos (perfil lip?dico, glicemia e fun??o hep?tica), medida da espessura endometrial, o registro di?rio de queixas relacionadas com o tratamento e a evolu??o de medidas antropom?tricas {?ndice de Massa Corporal(IMC), Circunfer?ncia da Cintura(CC) e Raz?o cintura/quadril(RCQ)}.Resultados: Cinquenta e sete participantes (87,7%) conclu?ram o estudo. Ao final de 12 semanas, ao se comparar os dois grupos, em rela??o aos valores basais, observa-se: no GT uma diminui??o significativa nos sintomas climat?ricos: IMK (35,5 + 6,7 vs. 11,3 + 6,5) e GSC (31,9?4.6 vs. 19,8 + 10,5) p<0,001; melhora do perfil lip?dico com redu??o do Triglicer?deos (152,2 + 53,0 vs. 105,2 + 26,8)p<0,001, colesterol total (220,7 + 38,5 vs. 193,3 + 37,9) p=0,001 e LDL colesterol (144,7 + 36,9 vs. 129,0 + 43,6)p=0,03; redu??o em 25,7% na rela??o Triglicerideos/HDL-c, fator preditor de resist?ncia insul?nica e de risco para doen?a arterial coronariana. No mesmo grupo, observou-se redu??o de 21% na espessura endometrial em rela??o ao valor basal (8.1 ? 2.6 vs 6.4 ? 1.9; p<0,05), compat?vel com atrofia; n?o houve altera??es nos marcadores hep?ticos e nem relatos de efeitos colaterais que levassem a interrup??o do tratamento. Conclus?es: A tibolona mostrou-se eficaz para reduzir a sintomatologia climat?rica de mulheres na transi??o menopausal, com boa tolerabilidade e melhora no perfil lip?dico. A 1-xv atrofia endometrial sugere prov?vel seguran?a para o seu uso como agente terap?utico da transi??o menopausal.

Chapter 7 retraces Bolger’s four-month stint in the South Pacific with pianist Little Jack Little. The two were the first entertainers to interact with Americans in the South Pacific. The USO sent just Bolger and Little to the South Pacific because many of the territories they would tour were still considered unfit for women, even for female nurses; Japanese militants were still on some of the islands. The logistics of battle in these islands and the impacts on Bolger and Little, as well as their audiences, are discussed. Simultaneously, the author traces Gwen Bolger’s attempts to secure Bolger a contract for a film with Rita Hayworth while Bolger was abroad. British director Victor Saville wanted Bolger for a supporting role in his forthcoming adaptation of the play Heart of the City. The film would be a Technicolor musical, telling the story of a London variety theater that refused to close for even a single performance during the Blitz.
