Determinacion de las relaciones polimorficas entre Teladorsagia circumcincta (Stadelmann, 1894) y Teladorsagia trifurcata (Ransom, 1907) en condiciones experimentales

En el presente estudio se demostró que Teladorsagia circumcincta (Stadelmann, 1894) y T. trifurcata (Ransom, 1907), nemátodes Trichostrongylidae de la sub-família Ostertagiinae, parasitan un espectro de hospedadores similares. La ausencia de barreras reproductivas entre T. trifurcata y T. circumcincta, así como la estabilización rápida de las proporciones de las dos entidades en el seno de la población, evidencia que T. trifurcata es un morfo de T. circumcincta.

An outbreak of dengue virus at Rio de Janeiro - 1986

Dengue virus type 1 has been isolated in Aedes albopictus cell strain, from sera of patients living in the Nova Iguaçu county, by Rio de Janeiro. The clinical picture was characterized by fever, headache, retrobulbar pain, backache, pains in the muscles and the joints and prostration. Studies in paired sera confirmed the presence of recent infection by dengue virus type 1. The outbreak reached adjacent areas, including Rio de Janeiro city (May, 1986).

Prévention des alcoolisations aiguës a l'adolescence: quel rôle pour le médecin de famille [Prevention of binge drinking in adolescents: do family doctors have a role to play?].

Binge drinking has nearly become the norm for young people and is thus worrying. Although alcohol use in males attracts more media attention, females are also frequently affected. A variety of preventive measures can be proposed: at the individual level by parents, peers and family doctors; at the school and community level, particularly to postpone age of first use and first episode of drunkenness; at the structural level through a policy restricting access to alcohol for young people and increasing its price. Family doctors can play an important role in identifying at risk users and individualising preventive messages to which these young people are exposed in other contexts.

Estudos bionômicos de Dipetalogaster maximus (Uhler, 1894) (Hemiptera - Triatominae): II - Influência da dieta sobre o ciclo biológico e resistência ao jejum

Avaliou-se a influência de dois tipos de dieta na cronologia da ontogênsese de Dipetalogaster maximus. Alimentou-se um grupo em sangue de camundongos normais (C) e outro em sangue de pombos (P). Ambos foram mantidos em estufa B.O.D. a 28ºC e 65% U.R. O grupo alimentado em C, atingiu a fase adulta com X=130,1 dias e o grupo alimentado em P com X=145,68 dias. A percentagem total de mortalidade foi significativamente superior nos alimentados em P (63,71%) em relação aos alimentados em C (31,18%). Quanto á resistência ao jejum, o período de sobrevivência foi acentuadamente maior para o grupo alimentado em C. Principalmente nos 3º, 4º e 5º estádios. Estas observações complementam nossos registros anteriores desta espécie, mantida nas mesmas condições, sobre: fertilidade das fêmeas, ritmo de postura, viabilidade dos ovos e curva da mortalidade x fertilidade.

Genetical exchanges between one Biomphalaria glabrata (Gastropoda: Planorbidae) and a varying number of partners

When one pigmented Biomphalaria glabrata is mated with 1 to 20 albino snails, the percentage of albino parent producing pigmented offspring decreases while the percentage of parent laying albino offspring increases. If the number of snaisl/group increases, the mean duration of the use of allosperm decreases.

Duration of pairing and use of allosperm in Biomphalaria glabrata (Gastropoda: Planorbidae)

Virgin homozygous black pigmented and albino Biomphalaria glabrata are paired during a period varying from 1 to 20 days. The rate of cross-fertilized parents is statistically similar for the various lengths of pairing. As a whole, nearly 80% of the albino snails produce a pigmented progeny. This production begins as soon as the snails are mated and continues after their separation. To measure the actual use of the allosperm, its use during the postmating period must be added to the length of mating. So, it appears that the real use of the allosperm is statistically constant (mean slightly inferior to 8 weeks) and not related to the length of the previous pairing.

La reconfiguració de la frontera hispano-marroquina (1986-2010)

Projecte de recerca elaborat a partir d’una estada a la Universitat Abdelmalek Essaadi, Marroc durant gener i febrer de 2007. S’analitzen els principals aspectes del procés de reconfiguració de la frontera hispano-marroquina, que segueix l’accés d’Espanya a la Unió Europea, l’any 1986. L'estudi s’estructura en tres parts, a través de les quals s’exploren les dimensions geopolítica, funcional i simbòlica del procés de refronterització. Partint de l’escenari general de la frontera hispano-marroquina, l’anàlisi s’aproxima gradualment als escenaris particulars construïts a l’entorn de les fronteres euro-africanes de Ceuta i Melilla –les dues ciutats magribines sota sobirania espanyola. D’aquest manera es descriu com el procés tripartit de refronterització ha forjat la geografia actual d’aquest peculiars segments de la frontera entre la UE/Espanya i el Marroc. L'anàlisi conclou tot subratllant com la frontera hispano-marroquina està condicionada per la creixent divergència entre la implementació de les necessitats securitàries de la frontera exterior de la UE i la gestió fronterera del lliure comerç.

Aspectos da biologia do Aedes albopictus (Skuse, 1894) (Diptera: Culicidae), a nível de campo

After the Aedees albopictus has been discoved by Neves & Espinola (1987) at Minas Gerais state, we begun studying some biologic aspects, such as breeding places, host preference, times of feeding and the preferred places for blood feeding.

La médecine de famille en Suisse à l'horizon 2030: quelle place pour la délégation des tâches médicales. [Family practitioners in Switzerland by 2030: which roles for medical task delegation?]

Due to population aging, by 2030 Switzerland may face a demand of 24 million family practitioner visits, a growth of 13 percent from the 2005 level. This result is based on the assumption that the per capita demand for doctor visits remains what was observed in 2005 by age groups and sex. During the same period, the total number of practitioners may decrease by 14 percent whereas the female proportion of such practitioners may double. These changes may cause a 33 percent decrease in the supply of physician visits to reach only 14 millions. The comparison of the demand and supply of family doctor visits reveals that by 2030, 10 million visits may be unmet which represents 40 percent of the demand. On the supply side, a full scale implementation of task delegation may partially reduce that gap (minus 2 millions). On the demand side, improved health status may bring in a larger decrease in the needs for visits (minus 4 million).

Estudos bionômicos de Dipetalogaster maximus (Uhler, 1894) (Hemiptera, Reduviidae, Triatominae): III. Dinâmica populacional

A population dynamics study of D. maximus was caried out under laboratory condictions (28-C e 65% ñ 5% U.R.) and the methodology was the same that have been used for hearing this insects. In order to evaluate the population growth rate of this species, during a 24 months period, five colonies started with a couple recently emerged were observed. Each couple (a male and a female) was mantained in a glass container measuring 20 cm of diameter and 20 cm in height with filter paper on the botton. The insects were monthly feeding with normal mice blood, and at this day the number of eggs, nymphal stages and adults was registered. All graphical representations of the populations growth rate showed the same shape. It was found that the average of nymphal stage represented 64.31% of the hole population whereas the oviposition curved showed to be inverse to this one (28.57%) a small percentage of adults was found: males 3.85% and females 3.12%. In this study observations on the biologycal cycle, longevity and fertility rates were also carried out.
