Bacterial nanocellulose (BNC) is considered a promising alternative to microcrystalline cellulose, as well as an ingredient in low-calorie dietary products. However, the risks of BNC when consumed with food are not well characterized. The aim of this study is to investigate the impact of BNC on immune function, the intestinal microbiome, intestinal barrier integrity, and allergic sensitization in subacute experiments on rats.

Mixed-conducting perovskites containing nondilute Fe─serving as electrodes, catalysts, and sensors─can support large, electronically accommodated excursions in oxygen content, typically controlled by temperature, bias, and gas atmosphere. Instead, we investigated the ability of low-fluence, above-bandgap illumination to adjust oxygen stoichiometry and drive oxygen fluxes in nondilute Sr(TiFe)O ( = 0.

However, studies on the risks of consuming BNC in food are limited, and it is not yet approved for use in food in the US, EU, and Russia.
Aim: This study aims to perform a toxicological and hygienic assessment of the safety of BNC in a subacute 8-week administration in rats.
After acute infection with the SARS-CoV-2 virus, up to 10 % of affected individuals suffer from long-term health impairments, also referred to as "Post-COVID". In Germany, specialized outpatient clinics have been established to care for patients with Post-COVID. A structured survey of the care situation is not yet available, but essential for a demand-oriented care.
