Flavoured-air inhalers containing essential oils are marketed as safe, natural alternatives to smoking and vaping, yet their potential respiratory toxicity remains effectively unexamined. Manufacturers claim safety based on "100% natural" ingredients, despite evidence that essential oil inhalation can cause adverse respiratory effects. Our objective was to assess the in vitro toxicity of six commercially available flavoured-ai...

Background and aims Early season weather fluctuations significantly impact corn ( Zea mays L.) seedling establishment and soil nitrogen availability. This study investigated the effect of flooding duration and temperature after planting on corn emergence, seedling biomass and soil inorganic nitrogen content supplemented by polymer-coated urea fertilizer. Methods A controlled environment experiment was conducted using a split-p...

Climate change is disproportionately warming the Arctic, leading to changes in weather patterns that affect breeding phenology for many Arctic species. Despite extensive research on non‐predatory birds, few studies have examined the impacts of climate change on higher trophic levels, especially those comparing breeding phenology and productivity between migratory and resident species. Our study used long‐term monitoring data f...

Flight in birds is supported by the presence of wing feathers known as remiges. Particularly, the asymmetrically shaped primary feathers ( Remiges primarii ) generate the necessary lift that allows a bird to take off. These feathers are supplemented with keratinous microstructures called hooklets. The interlocking ability with the opposing posterior barbules creates a continuous surface referred to as the feather’s vane. Using...

Age-related decline in left ventricular (LV) diastolic function is a hallmark of cardiac aging and an early precursor to cardiovascular disease. While dyslipidemia is a known driver of coronary heart disease (CHD), the molecular pathways linking lipid metabolism to cardiac aging and subsequent CHD risk remain poorly understood. Furthermore, longitudinal lipidomic profiling of cardiac aging in large human populations has not be...
