We know little about the ability to explore and navigate large-scale space for people with intellectual disability (ID). In this cross-syndrome study, individuals with Down syndrome (DS), individuals with Williams syndrome (WS) and typically developing children (TD; aged 5-11 years) explored virtual environments with the goal of learning where everything was within the environment (Experiment 1) or to find six stars (Experiment 2). There was little difference between the WS and DS groups when the goal was simply to learn about the environment with no specific destination to be reached (Experiment 1); both groups performed at a level akin to a subset of TD children of a similar level of non-verbal ability.

This research investigates their existence in the French Armed Forces, in terms of the impact on military operative response and military readiness. As no previous studies have evaluated the weight status of the whole French Armed Forces, this work assesses the situation for the first time in France.

In this context, we have previously identified an active RiPP, the Ruminococcin C1, naturally produced by E1, a symbiont of the healthy human intestinal microbiota. This RiPP, subclassified as a sactipeptide, requires the host digestive system to become active against pathogenic Clostridia and multidrug-resistant strains.

Even with triple and quadruple antibiotic therapies, shows increased prevalence of resistance to conventional antibiotics and treatment failure. Due to their pore-forming activity, antimicrobial peptides (AMP) are considered as a good alternative to conventional antibiotics, particularly in the case of resistant bacteria.

In two experiments, participants learned a route through a virtual environment until they reached a learning criterion. They were then asked to externalize their spatial knowledge in a verbal description task, a landmark recognition task, or a map completion task.

This implies a firm, unequivocal, and precise doctrine for all stages of care. Medical and surgical triage allows a logical classification of victims according to severity of injury, the necessity of treatment and the degree of urgency.

The mortality of gunshot wounds of the heart is 45%, among the wounded arriving at the hospital. The suspicion of wound heart with an inlet in the heart area (limited by costal awnings down, clavicles top, and mid-clavicular line outside) and pericardial effusion remains a surgical indication.

Two aspects of navigation were investigated in these groups, using virtual environments (VE): route knowledge (the ability to learn the way from A to B by following a fixed sequence of turns) and configural knowledge (knowledge of the spatial relationships between places within an environment).
Methods: Typically developing (TD) children aged 5 to 11 years (N = 93), individuals with DS (N = 29) and individuals with WS (N = 20) were presented with a sparse and a rich VE grid maze.
The ability to navigate new environments has a significant impact on the daily life and independence of people with learning difficulties. The aims of this study were to investigate the development of route learning in Down syndrome (N = 50), Williams syndrome (N = 19), and typically developing children between 5 and 11 years old (N = 108); to investigate use of landmarks; and to relate cognitive functions to route-learning ability in these groups. Overall, measures of attention and long-term memory were strongly associated with route learning, even once non-verbal ability was controlled for.

A sponge drug is used with some actions of resection and wide dissection, without knowledge of the eligibility of patients. In this study, we sought to identify clusters of patients for which the medicated sponge enhances tissue sealing.

The walking times of older female adults with or without any walking impairment and of healthy young adults were recorded on a walkway representing a road section. Participants also performed actual and imagined crossings of this "road" as well as a duration production task.

The Lille Apathy Rating Scale (LARS) has been validated in several different contexts, but the lengthy administration time means that it is mostly recommended for research use. The aim of the present study was to validate a short form of the LARS for use in everyday practice.

The ability to learn routes though a virtual environment (VE) and to make a novel shortcut between two locations was assessed in individuals with DS (N=10) and control participants individually matched on mental age (MA) or chronological age (CA). The results showed that most of the participants with DS were able to learn routes through the VE, even though they needed more trials than the CA controls to reach the learning criterion.

Background: The present study was aimed at investigating the selection of landmarks by individuals with intellectual disability (ID). The hypothesis was that they would be less efficient than individuals without IDs in the selection of landmarks when learning a new route.
Methods: The experiment took place in a natural setting with a group of participants with ID and a group of control participants matched by chronological age.

The aim of this study was to investigate route-learning ability in 67 children aged 5 to 11years and to relate route-learning performance to the components of Baddeley's model of working memory. Children carried out tasks that included measures of verbal and visuospatial short-term memory and executive control and also measures of verbal and visuospatial long-term memory; the route-learning task was conducted using a maze in a virtual environment. In contrast to previous research, correlations were found between both visuospatial and verbal memory tasks-the Corsi task, short-term pattern span, digit span, and visuospatial long-term memory-and route-learning performance.

Participants explored two routes (A ⇔ B and A ⇔ C) until they reached a learning criterion. Then, they were placed at B and were asked to find the shortest way to C (B ⇔ C, five trials).
