Global food security demands sustainable alternatives to the conventional feed ingredient wheat. Nutrient-dense diploid potatoes (HQP) represent candidates due to their enriched phytochemical profiles, including high levels of vitamin C and lutein. However, their dietary utilization is constrained by endogenous anti-nutritional factors (ANFs), primarily solanine and trypsin inhibitors. Using a zebrafish model, we demonstrate that these ANFs trigger intestinal dysbiosis and an oxidative-inflammatory response. Mechanistically, this adverse gut environment suppresses the mTOR pathway, as evidenced by reduced phosphorylation of S6K1 and 4E-BP1, ultimately leading to growth depression. To address this toxicological barrier, we integrated genetic selection (diploid HQP) with thermal processing (steam-cooking). Quantitative analysis revealed that while thermal processing effectively reduced ANF concentrations to physiologically safe levels, the HQP matrix retained significantly higher residual concentrations of vitamin C, lutein, and zeaxanthin compared to conventional tetraploid (C88) and wheat-based diets. Mechanistically, protein-level evidence confirmed that this processed HQP formulation promoted the total NRF2 and suppressed NF-κB P65 accumulation. This metabolic shift attenuated inflammation, reactivated mTOR signaling, and subsequently enhanced growth performance and digestive capacity. Our findings establish a mechanistic framework demonstrating how integrated genomic design and processing strategies facilitate the functional utilization of high-phytochemical crops in sustainable food systems.

Abstract Indoor air quality can be improved by coatings that adsorb harmful volatile organic compounds (VOCs). In the present work, bio-based and VOC-adsorbing wood coatings were fabricated from polyphenols extracted from spruce bark, biochar produced from mixtures of spruce and pine bark, and a polyamine crosslinker. The bark-based biochar was doped with a catalyst (MnO 2 ) to enable continuous elimination of the adsorbed VOCs so that the coatings would not become saturated. The coatings formed a homogenous and smooth layer that covered the whole surface of the wood and showed excellent adhesion to the substrate, while their VOC removal efficiency was dependent on the pollutant type and the coating weight. The best performance was achieved toward formaldehyde, followed by chloroform and methyl ethyl ketone. Thick coatings (200–220 g/m 2 ) reached a formaldehyde removal of 62%, with the coating base and the biochar contributing nearly equally to the VOC removal. Overall, the bark-based coatings showed good potential for improving indoor air quality, but the surface wettability of the coated spruce wood was high. Despite the presence of biochar and nitrogen-containing aromatic compounds, the coatings did not appear to improve the reaction to fire of the wood.

The lecture provides practical guidance on research proposal development and international funding opportunities, with a particular focus on Horizon Europe. It covers how to identify suitable funding calls, understand call requirements and eligibility, develop competitive research ideas, formulate clear and measurable objectives, and design a sound research methodology. It also explains the main components of a Horizon Europe proposal, including Part A and Part B, and provides step-by-step guidance on writing the Excellence, Impact, and Implementation sections. The lecture further addresses international partnership and consortium building, work packages, deliverables, milestones, risks, staff effort, budget allocation, dissemination, exploitation, communication, and proposal evaluation criteria. Real and illustrative project examples, including collaborations between Norwegian and African universities, are used to connect proposal-writing principles with practical research funding experience.
