Landscape features are known to alter the spatial genetic variation of aboveground organisms. Here, we tested the hypothesis that the genetic structure of belowground organisms also responds to landscape structure. Microsatellite markers were used to carry out a landscape genetic study of two endogeic earthworm species, Allolobophora chlorotica (N = 440, eight microsatellites) and Aporrectodea icterica (N = 519, seven microsatellites), in an agricultural landscape in the North of France, where landscape features were characterized with high accuracy. We found that habitat fragmentation impacted genetic variation of earthworm populations at the local scale. A significant relationship was observed between genetic diversity (H , A ) and several landscape features in A. icterica populations and A. chlorotica. Moreover, a strong genetic differentiation between sites was observed in both species, with a low degree of genetic admixture and high F values. The landscape connectivity analysis at the regional scale, including isolation by distance, least-cost path and cost-weighted distance approaches, showed that genetic distances were linked to landscape connectivity in A. chlorotica. This indicates that the fragmentation of natural habitats has shaped their dispersal patterns and local effective population sizes. Landscape connectivity analysis confirmed that a priori favourable habitats such as grasslands may constitute dispersal corridors for these species.

Cancers of the digestive system are major contributors to global cancer-associated morbidity and mortality, accounting for 35% of annual cases of cancer deaths. The etiologies, molecular features, and therapeutic management of these cancer entities are highly heterogeneous and complex. Over the last decade, genomic and functional studies have provided unprecedented insights into the biology of digestive cancers, identifying genetic drivers of tumor progression and key interaction points of tumor cells with the immune system.

Internationally, the need to have service user involvement (the 'voice' of recovery journeys) as an established and significant feature on the landscape of professional development has been widely discussed in the area of mental health nursing (MHN) education for over a decade. Service user involvement contributes to a different understanding, bringing 'new' ways of knowing in nursing education and potentially new ways of practicing within mental health services. The objective of this co-produced research was to investigate the current local 'state of play' of service user involvement in MHN student education in a regional university in the Republic of Ireland.

Vitamin A and its primary active derivative, all-trans retinoic acid (RA), are endogenous signaling molecules essential for numerous biological processes, including cell proliferation, differentiation, and immune modulation. Owing to its differentiation-inducing effect, RA was the first differentiating agent approved for the clinical treatment of acute myeloid leukemia. While the classical mechanisms of RA signaling involve nuclear receptors, such as retinoic acid receptors (RARs), emerging evidence suggests that RA also engages in non-covalent and covalent interactions with a broader range of proteins.
