Prenatal Androgen Exposure Induces Anxiety-Like Behavior in Ewes.

Introduction: In humans, prenatal androgen excess can lead to a broad spectrum of pathologies in adulthood, including polycystic ovary syndrome (PCOS). Women with PCOS present a variety of reproductive and metabolic disturbances and they also face increased risk to develop neuropsychiatric disorders such as depression and anxiety. Despite the high prevalence, the cause of depressive and anxiety symptoms is not fully elucidated.

Cutaneous application of SecurePig® FLASH, a Pig appeasing pheromone analogue, facilitates adaptation and manages social behavior during feeding in semi-extensive conditions.

Background: Farm animals face several challenges throughout their lives, which can affect both their welfare and their productivity. Promoting adaptation in animals is one way of limiting these consequences. In various animal species, the use of maternal appeasing pheromones is efficient to reduce aggressiveness, improve adaptation and thus ensuring better welfare and productivity.

Vulnerability to semantic and phonological interference in normal aging and amnestic mild cognitive impairment (aMCI).

Objective: To determine whether the increased vulnerability to semantic interference previously observed in amnestic mild cognitive impairment (aMCI) is specifically associated with semantic material or if it also affects other types of material, suggesting generalized executive and inhibitory impairment.

Method: Seventy-two participants divided into two groups (33 aMCI, 39 normal control [NC]) matched for age and education were included. They completed a comprehensive neuropsychological examination, the French version of the Loewenstein Acevedo Scale for Semantic Interference and Learning (LASSI-L; semantic interference test), and a homologous experimental phonological test, the phonological interference and learning test.

Montreal Cognitive Assessment and the Clock Drawing Test to Identify MCI and Predict Dementia in Isolated REM Sleep Behavior Disorder.

Background And Objectives: Patients with isolated/idiopathic REM sleep behavior disorder (iRBD) are at high risk for developing mild cognitive impairment (MCI) and dementia with Lewy bodies (DLB). However, there is a lack of scientific knowledge regarding the accuracy of cognitive screening tools to identify these conditions in iRBD. This study aimed to determine in iRBD the psychometrics of 2 screening tests to discriminate patients with MCI and those at risk of DLB.

Learning and vulnerability to phonological and semantic interference in normal aging: an experimental study.

This study compares semantic and phonological interference vulnerability across the full range of learning processes. : 43 controls aged 61-88 underwent a neuropsychological examination, French adaptation of the LASSI-L, and an experimental phonological test, the TIP-A. Paired sample -tests, factorial ANOVA and hierarchical regressions were conducted, psychometric properties were calculated.
