The subgenus Migonemyia Galati 1995 (Diptera, Psychodidae, Phlebotominae), with description of a new species Migonemyia vaniae: a review

The capture of a new species of the subgenus Migonemyia Galati, 1995 (Diptera, Psychodidae, Phlebotominae), Migonemyia vaniae sp. nov. in the Ribeira Valley, state of São Paulo, Brazil, together with the other two species: Mg. migonei (França, 1920) and Mg. rabelloi (Galati & Gomes, 1992) lead us to review this subgenus. The new species was described and illustrated. The genitalia of the two other species were also illustrated and some genital characteristics (number of setae on the gonocoxite tuft, ejaculatory ducts and pump and ducts/pump ratio; and number of setae on the tergite VIII of the females) considered important to differentiate the three species, including five populations of Mg. migonei (from Northeastern, Southeastern, and Southern Brazilian regions and of Peru) were submitted to variance analyses. The Mg. migonei population of Northeastern Brazilian region showed distinct smaller values (P < 0.05) than the other Brazilian populations studied as regarding these characteristics. The capture of both sexes of these three species in sympatry confirms the association between the sexes of Mg. rabelloi, recognised as doubtful when this species was originally described. Identification keys for male and female of the three species are presented.

Research on individual social policy preferences has highlighted a number of socio-structural cleavages as determinants. Studies investigating public opinion on the various redistributive schemes that make up today's welfare states have shown the relevance of class-related factors such as income or education as key explanatory variables (Ferrera 1993; Taylor-Gooby 1995, 1998; and Svallfors 1997). More recent studies, however, have suggested that other factors are also likely to play a role. Among these, the most important are age, gender, and individual values (Armingeon 2006; Deitch 2004; and Roller 2000, 2002). The scenario that emerges from the existing literature is one of multiple intersecting cleavages, but it remains unclear as to what today is the relative weight and specific impact of each of these cleavages.

Análisis de contenido de la lista dedistribución IweTel (1998-2000)

La llista de distribució s'ha mostrat durant l'última dècada com una eina eficaç a l'hora de vertebrar la comunicació professional. De fet, és un primer pas cap a les comunitats virtuals. En aquest article s'estudia l'evolució d'un cas concret, IweTel, i de l'ús que els subscriptors van fer -ne, a partir de l'anàlisi de contingut dels missatges que van ser enviats entre 1998 i 2000. De l'estudi es desprèn que es tracta d'una llista utilitzada fonamentalment per a la comunicació professional i l'intercanvi d'informació, encara que pateix d'una falta notòria d'implicació activa per part dels seus subscriptors. Per altra banda, encara que han estat notables les millores fruit de la moderació, hi ha una absència viciosa de contingut científic o acadèmic en els debats desenvolupats.

La participació en projectes telemàtics : noves oportunitats, nous serveis

La Biblioteca de la Universitat Oberta de Catalunya va començar a funcionar durant el curs 1995-1996. Des d'un bon principi, la singular concepció d'aquesta nova universitat a distància i la manca d'experiències similars en les que basar el desenvolupament dels seus serveis bibliotecaris va fer palesa la necessitat de donar una especial atenció al seguiment i l'aplicació de les noves tecnologies emergents. En els dos anys transcorreguts aquest plantejament s'ha vist consolidat i, en l'actualitat, està incorporat als objectius i a les línies d'actuació de la Biblioteca.

Prevalence and resistance mutations of non-B HIV-1 subtypes among immigrants in Southern Spain along the decade 2000-2010.

Most of the non-B HIV-1 subtypes are predominant in Sub-Saharan Africa and India although they have been found worldwide. In the last decade, immigration from these areas has increased considerably in Spain. The objective of this study was to evaluate the prevalence of non-B subtypes circulating in a cohort of HIV-1-infected immigrants in Seville, Southern Spain and to identify drug resistance-associated mutations. METHODS: Complete protease and first 220 codons of the reverse transcriptase coding regions were amplified and sequenced by population sequencing. HIV-1 subtypes were determined using Stanford University Drug Resistance Database, and phylogenetic analysis was performed comparing multiple reported sequences. Drug resistance mutations were defined according to the International AIDS Society-USA. RESULTS: From 2000 to 2010 a total of 1,089 newly diagnosed HIV-1-infected patients were enrolled in our cohort. Of these, 121 were immigrants, of which 98 had ethical approval and informed consent to include in our study. Twenty-nine immigrants (29/98, 29.6%) were infected with non-B subtypes, of which 15/29 (51.7%) were CRF02-AG, mostly from Sub-Saharan Africa, and 2/29 (6.9%) were CRF01-AE from Eastern Europe. A, C, F, J and G subtypes from Eastern Europe, Central-South America and Sub-Saharan Africa were also present. Some others harboured recombinant forms CRF02-AG/CRF01-AE, CRF2-AG/G and F/B, B/C, and K/G, in PR and RT-coding regions. Patients infected with non-B subtypes showed a high frequency of minor protease inhibitor resistance mutations, M36I, L63P, and K20R/I. Only one patient, CRF02_AG, showed major resistance mutation L90M. Major RT inhibitor resistance mutations K70R and A98G were present in one patient with subtype G, L100I in one patient with CRF01_AE, and K103N in another patient with CRF01_AE. Three patients had other mutations such as V118I, E138A and V90I. CONCLUSIONS: The circulation of non-B subtypes has significantly increased in Southern Spain during the last decade, with 29.6% prevalence, in association with demographic changes among immigrants. This could be an issue in the treatment and management of these patients. Resistance mutations have been detected in these patients with a prevalence of 7% among treatment-naïve patients compared with the 21% detected among patients under HAART or during treatment interruption.
