Understanding the pathogenesis of paratuberculosis (PTB), caused by Mycobacterium avium subspecies paratuberculosis (MAP), is essential in the management of this economically important disease. MAP strains are known to differ genotypically, which could contribute to differences in strain virulence and disease outcomes. The behaviour of MAP inside the host and the mechanisms utilized by MAP to overcome the host defence system a...

Intratumoral injection of immune stimulants could potentially reverse the immunosuppressive tumor microenvironment, but the injected drug rapidly washes out into the systemic circulation. This results in systemic toxicity, and reduced efficacy, potentially requiring daily injections to generate an antitumor immune response. To address this problem, we developed an extended-release hydrogel that retains the immunotherapy agent...

The definition of biological sex has become a renewed focus of societal debate, fuelled by the conflation of biological principles with discussions of human gender diversity. Here, we argue that conceptual clarity critically depends on separating these domains. Drawing on evolutionary theory and empirical evidence, we maintain that biological sex is best defined as a binary classification of male and female reproductive strate...

This study investigates lithium-caesium-tantalum (LCT) pegmatites and associated pegmatites and granites in the Varuträsk area, northern Sweden, using a mineral systems approach (i.e. source-transport-trap). The research incorporates geological mapping both regionally and underground, analysis of geological structures and host rock competency, 3D modelling, lithogeochemistry, and zircon-monazite U–Pb SIMS geochronology to asse...

Effective fishery management policy depends on accurate life‐history data, particularly for harvested species. Longevity is a core life‐history trait that is directly related to annual survival and lifetime reproductive potential, but fish longevity is generally not well documented, particularly for long‐lived species. We used capture–mark–recapture data spanning 44 years as an alternative method to estimate sex‐specific adult...
