Pragmatic impairments are largely documented, yet rarely considered in clinical practice, also owing to a poor characterization of pragmatic profiles across conditions, as well as some overlap with theory of mind (ToM) in the conceptualization of pragmatics. Here, we present the outcome of a 10-year programme that started with creating a novel test, the Assessment of Pragmatic Abilities and Cognitive Substrates (APACS)-which we evolved by its application alongside ToM assessment in seven clinical groups (i.e.

The possibility of duplicating the efficiency and selectivity of natural processes under laboratory conditions remains a significant challenge for organic chemists. In this letter, we demonstrated that it is possible to introduce pinpoint modifications and to reshape the terpene skeleton of easily available oleananes in a biomimetic fashion. Furthermore, aromatization of the A ring of the triterpene system is reported here for the first time, mimicking what occurs exclusively in nature in sediments.

Cognitive impairment after stroke is heterogeneous: there is no strict correspondence between brain damage and magnitude of deficit or recovery. Protective factors such as cognitive or brain reserve have been invoked to explain the mismatch. Here, we consider the opposite point of view: the instances in which this protection is overturned.

The photoreactivity of steroids represented a hot topic in the middle of the last century and in this project, we "rediscover" it through the exploration of the photochemical behavior of Δ-3-keto-steroids. In terms of number of products obtained, the photochemistry of Δ-3-keto-steroids is less complicated than that of Δ-3-keto- and Δ-3-keto-steroids, furnishing an efficient and tunable method to remodel the classic steroid 6/6/6/5 ring system. In this scenario, this approach can represent a simple strategy to interconvert a class of easily available steroids to another difficult-to-access from natural sources.

The discovery of new glycosylation reactions is still a major challenge in carbohydrate chemistry. Traditional glycosylation reactions require the preparation of sugar donors with anomeric active or latent leaving groups. Dehydrative glycosylation is a fascinating alternative that enables the direct formation of the glycosidic bond from the hemiacetal, eliminating the need for (sometimes unstable) leaving groups, and allowing to reduce reaction, work-up, and purification times.

It has been suggested that Gerstmann's syndrome is the result of subcortical disconnection rather than emerging from damage of a multifunctional brain region within the parietal lobe. However, patterns of white matter tract disconnection following parietal damage have been barely investigated. This single case study allows characterising Gerstmann's syndrome in terms of disconnected networks.
