The AA describe the realise of an open circuit exposure chamber: it enables to reach solvent concentration levels that are continuously monitored and kept within the limits of acceptability. The room can be employed in studies and experimental researches on the respiratory absorption levels of airborne pollutants in man. The following data are reported: on microclimatic parameters, on the monitoring of CO2 concentration in the room when someone is inside, on the solvent concentration measures in different points of the room, on the monitoring of the quickness to reach the steady-state and wash-out in the room, on the available concentration ranges.

A standardized polyphenol-enriched fraction (IPHRFPPEF) was formulated into a phospholipid complex (IPHRFPPEF-PC) to enhance oral bioavailability and evaluate stability, toxicity, and in vivo anti-inflammatory activity in Sprague Dawley rats. IPHRFPPEF was prepared from crude extract using XAD-HP7/Diaion-HP20 resin column chromatography and analyzed via HPLC and NMR. Total phenolic and flavonoid contents were quantified, with IPHRFPPEF showing higher values than the crude fraction.

Osmotic stresses during cryoprotectant loading induce changes in cellular volume, leading to membrane damage or even cell death. Appropriate model-guided mitigation of these osmotic gradients during cryoprotectant loading is currently lacking, but would be highly beneficial in reducing viability loss during the loading process. To address this need, we reformulate the two-parameter formalism described by Jacobs and Stewart for cryoprotectant loading under the constraint of constant cell volume.

Background: Chronic and excessive alcohol consumption is the leading cause of death due to chronic liver disease. Alcohol-related liver disease (ALD) encompasses a broad spectrum of clinical and pathological features, ranging from asymptomatic and reversible pathologies to hepatocellular carcinoma (HCC), a highly prevalent and deadly liver cancer. Indeed, alcohol consumption is one of the main worldwide etiologies of HCC.

Developing orally administered pediatric formulations presents significant challenges due to the unique characteristics of pediatric patients. Terbinafine hydrochloride (TER), a powerful antifungal agent, is effective against various fungal infections, including Tinea capitis, which is common in children. However, its low aqueous solubility necessitates innovative pharmaceutical strategies to enhance its effectiveness.

Lipases from the basidiomycete fungus Ustilago maydis are promising but underexplored biocatalysts due to their high homology with Candida antarctica lipases. This study provides a comprehensive characterization of a recombinant CALB-like lipase from U. maydis, expressed in Pichia pastoris (rUMLB), and compares its properties with those of the well-studied recombinant lipase B from C.
