For many years after the discovery of the two stable isotopes of boron (B,B) in 1920 they were not used as tracers in the soil-plant system due to analytical constraints. However, with the advent of inductively coupled plasma mass spectrometry in the early 1980s, it became possible to measure precisely the natural variations of the B isotopes in biological systems. Nevertheless, up to the present time there is very little information in the literature on B variations in soils, plants, fertilizers and foodstuffs. Therefore, information on the potential of B as a tracer of B dynamics in natural- and agro-ecosystems remains limited. The relative abundance of the boron isotope ( B) in soils, plants and nutrient sources, and applications of variations in the natural abundance of B as a tracer of anthropogenic sources of nitrate contamination of water and the provenance of agricultural products are reviewed.

Further understanding of the molecular mediators of alternative RBC invasion phenotypes in endemic malaria parasites will support malaria blood-stage vaccine or drug development. This study investigated the prevalence of sialic acid (SA)-dependent and SA-independent RBC invasion pathways in endemic parasites from Cameroon and compared the schizont stage transcriptomes in these two groups to uncover the wider repertoire of transcriptional variation associated with the use of alternative RBC invasion pathway phenotypes. A two-color flow cytometry-based invasion-inhibition assay against RBCs treated with neuraminidase, trypsin, and chymotrypsin and deep RNA sequencing of schizont stages harvested in the first replication cycle in culture were employed in this investigation.

The Circumsporozoite Protein (PfCSP) has been used in developing the RTS,S, and R21 malaria vaccines. However, genetic polymorphisms within compromise the effectiveness of the vaccine. Thus, it is essential to continuously assess the genetic diversity of , especially when deploying it across different geographical regions.

Background: There has been a spate of recent cases of human alveolar echinococcosis (AE) in Alberta, Canada. Alveolar echinococcosis is caused by , which is prevalent among coyote populations and present in domestic dogs in Alberta.
Methods And Results: Using qPCR, we estimated the seasonal fecal prevalence of in coyotes and dogs in a multiuse recreation area close to Edmonton, Alberta, where we also setup remote cameras to model seasonal changes in the overlap in temporal activity and the spatial intensity of use among coyotes, humans, and dogs, as a proxy of potential transmission.

Everolimus presents significant dosing challenges due to between- and within-patient pharmacokinetic variabilities. This study aimed to develop and validate a model-informed precision dosing strategy for everolimus in liver transplant recipients. The dosing strategy was initially developed using retrospective data, employing nonlinear mixed-effects modeling.

The mechanical properties of dietary items are known to influence skull morphology, either through evolution or by phenotypic plasticity. Here, we investigated the impact of supplementary feeding of peanuts on the morphology of red squirrels () from five populations in Britain (North Scotland, Borders, Jersey and two temporally distinct populations from Formby (Merseyside)). Stable isotope analysis confirmed dietary ecology in 58 specimens.
