Autoradiography of Intracerebral Tumours in the Chick Embryo Model: A Feasibility Study Using Different PET Tracers.

Purpose: In addition to rodent models, the chick embryo model has gained attention for radiotracer evaluation. Previous studies have investigated tumours on the chorioallantoic membrane (CAM), but its value for radiotracer imaging of intracerebral tumours has yet to be demonstrated.

Procedures: Human U87 glioblastoma cells and U87-IDH1 mutant glioma cells were implanted into the brains of chick embryos at developmental day 5.

Hydrological and hydraulic drivers of microplastics in a rural river sourced from the UK's largest opencast coal mine.

Microplastics (MPs) are ubiquitous in river and freshwater ecosystems. However, the hydraulic and hydrological mechanisms that regulate the activation and emissions of MPs from both the land surface and subsurface into rivers are not well understood. This study aims to quantify the instream MP concentration and MP load in a remote headwater catchment river (Taff Bargoed, Wales UK), which drains the UK's largest opencast coal mine (Ffos-y-fran), over a two-year period.

Associations of behavioral, motivational, and socioeconomic factors with BMI among children and adolescents.

Background: Higher weight represents a significant health concern in youth and may be influenced by socioeconomic and behavioral factors. We investigated the relationship between BMI and parental education, nutritional health, eating culture, organized and non-organized physical activity (PA), motives for PA (weight loss/maintenance, enjoyment), and screen-time in children and adolescents.

Methods: 677 2- to 11-year-olds (young-age-group) and 464 12- to 20-year-olds (old-age-group) from Leipzig, a city in Germany, participated.

Oat Kilning and Its Effects on Liquid Oat-Base Production.

The aim of this study was to give insights on the effects of an industrially relevant kilning method, with a focus on lipase inactivation and oat-base production. Storage of non-kilned, dehulled oat kernels in either room temperature or at 37 °C for up to 64 days led to increasing lipase activity with time, despite a decrease in moisture content and water activity, demonstrating the importance of kilning before storage. It was shown that the temperature and relative humidity used during the kilning had a major impact on both protein solubility and lipase inactivation.

Iron Oxides Fuel Anaerobic Oxidation of Methane in the Presence of Sulfate in Hypersaline Coastal Wetland Sediment.

Wetland methane emissions are the primary natural contributor to the global methane budget, accounting for approximately one-third of total emissions from natural and anthropogenic sources. Anaerobic oxidation of methane (AOM) serves as the major sink of methane in anoxic wetland sediments, where electron acceptors are present, thereby effectively mitigating its emissions. Nevertheless, environmental controls on electron acceptors, in particular, the ubiquitous iron oxides, involved in AOM are poorly understood.
