Treatment of Alzheimer's Disease in the New Era of Monoclonal Antibodies Against Cerebral Amyloid-β: Pharmacological Prescription and Knowledge in Argentina.

Background: Alzheimer's disease (AD) presents a significant global health challenge. Understanding the current and upcoming treatment landscape is crucial for effectively managing patients.

Objective: The aim of this study was to assess the pattern of prescription and knowledge about new therapies by physicians who treat AD patients in Argentina.

[Identification of restless legs syndrome in polysomnography studies and its association with other variables].

Introduction: Restless legs syndrome (RLS) is a movement disorder characterized by an uncontrollable urge to move the legs in response to an unpleasant sensation. The coexistence of RLS and other sleep and mood disorders may require adjustment in the therapeutic strategy. The objective of this study was to determine the prevalence of RLS in adults studied with polysomnography and to evaluate its association with other sleep and mood disorders.

Selective forces on the maintenance of outcrossing in an almost exclusively cleistogamous violet species.

Premise: Cleistogamous species constitute interesting study systems to resolve the longstanding question of how outcrossing is maintained given that seed production is ensured through selfing. In this work, we investigate the selective forces that allow the persistence of producing self-pollinated cleistogamous (CL) and chasmogamous (CH) flowers in Viola jaubertiana Marès & Vigin.

Methods: We monitored three populations at different elevation for two years, and studied the flowering phenology and the relative contribution of each flower morph to parental fitness.

Jacques Mehler's early psycholinguistic days in Paris.

This article first describes Jacques Mehler's initial efforts to make psycholinguistics and, more generally, the cognitive sciences better known during his first years in Paris. Two lines of research on sentence perception, that we conducted in collaboration with Jacques, are then presented to illustrate his focus. In the Seventies, sentence perception was a central topic in psycholinguistics, with contrasting proposals of syntactic autonomy and interactivity being confronted.

Continuous variation in herkogamy enhances the reproductive response of to spatial variation in pollinator assemblages.

Herkogamy, the spatial separation of sex organs in hermaphroditic plants, has been proposed as a mechanism to reduce self-pollination and the associated processes of inbreeding and gamete wastage. Longitudinal herkogamy is the most frequent type, with two subtypes: approach herkogamy (anthers below the stigma), which is associated with diverse pollinator arrays, and reverse herkogamy (anthers above the stigma), associated with specialized, long-tongued pollinators. By using a herkogamy index that varied continuously from negative (reverse herkogamy) to positive (approach herkogamy) values, we studied the effect of continuous variation in herkogamy on pollinator attraction, selfing capability and plant fitness across three populations of differing in the relative abundance of long-tongued vs.
