Enhancement by diuretics of the antihypertensive action of long-term angiotensin converting enzyme blockade

Thirty-nine patients with various types of hypertension were treated by chronic blockage of the angiotensin converting enzyme, i.e. by twice daily administration of captopril, 50 to 200 mg p.o. The blood pressure reduction observed 1 hour following administration of the inhibitor was directly related to the baseline plasma renin activity (r=- 0.67, p < 0.001). Whenever blockade of the renin system alone did not lower blood pressure to normal levels additional sodium subtraction brought it under control. With the renin system neutralized, blood pressure becomes exquisitely sensitive to changes in sodium balance. Diuretics seem to preserve optimal natriuretic efficacy despite blood pressure reduction, probably because aldosterone levels are reduced and renal blood flow increases. Blockade of the renin system together with individually tailored salt subtraction provides an attractive new approach to long-term treatment of clinical hypertension.

Récits, imaginaires collectifs et forme d'action protestataire. Une approche constructiviste de la contestation antiraciste

Cet article vise à repenser l'influence de la culture sur les phénomènes contestataires par le biais des récits sociaux et imaginaires collectifs. Les narrations collectives mettent à disposition un stock spécifique de ressources culturelles et symboliques, elles façonnent les identités des acteurs et, finalement, elles dessinent des opportunités discursives qui facilitent ou, au contraire, limitent l'engagement et l'expression politique des acteurs contestataires. En examinant l'action des organisations antiracistes et des acteurs qui se solidarisent au sort des migrants en France et en Suisse, nous verrons que les imaginaires de la nation et les récits collectifs de la citoyenneté nous offrent des outils conceptuels qui nous permettent de comprendre la présence de ces acteurs dans l'espace public, le répertoire d'action qu'ils mobilisent pour porter leurs revendications dans la sphère politique, mais aussi le contenu de leurs interventions publiques.

The Anopheles albitarsis complex with the recognition of Anopheles oryzalimnetes Wilkerson and Motoki, n. sp. and Anopheles janconnae Wilkerson and Sallum, n. sp. (Diptera: Culicidae)

The Anopheles (Nyssorhynchus) albitarsis complex includes six species: An. albitarsis, Anopheles oryzalimnetes Wilkerson and Motoki, n. sp., Anopheles marajoara, Anopheles deaneorum, Anopheles janconnae Wilkerson and Sallum, n. sp. and An. albitarsis F. Except for An. deaneorum, species of the complex are indistinguishable when only using morphology. The problematic distinction among species of the complex has made study of malaria transmission and ecology of An. albitarsis s.l. difficult. Consequently, involvement of species of the An. albitarsis complex in human Plasmodium transmission is not clear throughout its distribution range. With the aim of clarifying the taxonomy of the above species, with the exception of An. albitarsis F, we present comparative morphological and morphometric analyses, morphological redescriptions of three species and description of two new species using individuals from populations in Brazil, Paraguay, Argentina and Venezuela. The study included characters from adult females, males, fourth-instar larvae, pupae and male genitalia of An. albitarsis, An. marajoara, An. deaneorum and An. oryzalimnetes n. sp. For An. janconnae n. sp. only characters of the female, male and male genitalia were analyzed. Fourth-instar larvae, pupae and male genitalia characteristics of all five species are illustrated. Bionomics and distribution data are given based on published literature records.

Comprehensive heart disease action plan for Andalusia 2005-2009 : Andalusian Public Health System

The Comprehensive Heart Disease Action Plan for Andalusia 2005-2009 has been prepared within the framework of the presentations made both in the 3rd Andalusian Health Action Plan and in the Quality Plan of the Public Health System. Consequently, as with these two referral instruments, the improvement in the health results for the citizens of Andalusia continues to be sought without wavering, specifically with regard to meeting the needs and expectations of the population affected by health problems in this area.

A new approach to real time traffic sign recognition based on colour information

The automatic interpretation of conventional traffic signs is very complex and time consuming. The paper concerns an automatic warning system for driving assistance. It does not interpret the standard traffic signs on the roadside; the proposal is to incorporate into the existing signs another type of traffic sign whose information will be more easily interpreted by a processor. The type of information to be added is profuse and therefore the most important object is the robustness of the system. The basic proposal of this new philosophy is that the co-pilot system for automatic warning and driving assistance can interpret with greater ease the information contained in the new sign, whilst the human driver only has to interpret the "classic" sign. One of the codings that has been tested with good results and which seems to us easy to implement is that which has a rectangular shape and 4 vertical bars of different colours. The size of these signs is equivalent to the size of the conventional signs (approximately 0.4 m2). The colour information from the sign can be easily interpreted by the proposed processor and the interpretation is much easier and quicker than the information shown by the pictographs of the classic signs

Confabulation in schizophrenia: a neuropsychological study.

Confabulation has been documented in schizophrenia, but its neuropsychological correlates appear to be different from those of confabulation in neurological disease states. Forty-five schizophrenic patients and 37 controls were administered a task requiring them to recall fables. They also underwent testing with a range of memory and executive tasks. The patients with schizophrenia produced significantly more confabulations than the controls. After correcting for multiple comparisons, confabulation was not significantly associated with memory impairment, and was associated with impairment on only one of eight executive measures, the Brixton Test. Confabulation scores were also associated with impairment on two semantic memory tests. Confabulation was correlated with intrusion errors in recall, but not false positive errors in a recognition task. The findings suggest that confabulation in schizophrenia is unrelated to the episodic memory impairment seen in the disorder. However, the association with a circumscribed deficit in executive function could be consistent with a defective strategic retrieval account of confabulation similar to that of Moscovitch and co-workers, interacting with defective semantic memory.
