Summary: Oromucosal films and wafers are convenient solid dosage forms for drug delivery. In this study, prednisolone containing chitosan-based mucoadhesive films and wafers were developed with different chitosan types. The mucoadhesive properties, drug release rate, and permeability of the formulations were evaluated. The results showed that chitosan type, solvent, and preparation method influenced the mucoadhesive properties, drug release rate, and permeability. The mucoadhesive wafers with a slower drug release rate and stronger mucoadhesion were considered promising alternatives to films.

Summary: Chitosan nanomaterials have gained attention in biomedicine for their high levels of biodegradability and biocompatibility, along with antimicrobial effects. Functional modification with other natural compounds, metallic antimicrobial particles, and antibiotics can enhance the efficiency of chitosan in wound dressing with antimicrobial activity. The antibacterial effect of chitosan is mainly associated with the leakage of intracellular content due to malfunction and altered permeability of the negatively charged cell membrane, on which chitosan is adsorbed. Additionally, chitosan nanoparticles possess favorable features of nanoparticles and their chitosan base, thereby exhibiting strengthened antibacterial potential. Polycations in chitosan nanoparticles target negatively charged bacterial membranes, resulting in a stronger effect on bacterial cells compared to pure chitosan.

Summary: By introducing MMPs responsive peptide chain GPLGVRGDG, the polymeric prodrug can be endowed with smart properties through a safe and simple method. In this study, it was found that during the doxorubicin delivery in TPGS(3350)-GPLGVRGDG-DOX&DOX micelles, the cleavage of the peptide chain triggers de-PEGylation, retaining the VRGDG sequence on the micelles' surface, which acts as a ligand to facilitate cell uptake and enhances cytotoxicity against 4T1 cells.

Summary: Currently, the majority of polyols used in the synthesis of polyurethane foams are derived from petrochemicals. However, due to the decreasing availability of crude oil, alternative resources such as plant oils, carbohydrates, starch, or cellulose need to be utilized as substrates for polyols. Chitosan, a biopolymer, shows promise as a candidate for polyol synthesis. This paper investigates the use of chitosan to obtain polyols and rigid polyurethane foams through various synthesis methods. The resulting chitosan-derived polyols were characterized and used to produce polyurethane foams with desirable properties. The chitosan-based polyols and polyurethane foams were found to be biodegradable.

Summary: This study investigated the fate of trace metals in anaerobic digestion of municipal solid waste (MSW) digestate-amended soil and the influence of pharmaceutical compounds on their behavior. The results showed that trace metals initially present in the digestate were transferred from the amended soil layer to the underlying soil layer over time, but no transfer was detected to deeper soil layers. Trace metals in soil were mostly in immobile and less bioavailable forms, while in the digestate-amended soil they were in more bioavailable forms. The presence of the antidiabetic drug metformin had no influence on trace metal behavior.

Summary: In the face of global warming and the energy crisis, it is crucial to reduce the emissions of greenhouse gases like CO2 and CH4 and recycle biomethane from landfill biogas. This study demonstrates the potential of converting glycerol, a by-product of biodiesel production, into activated carbon using potassium acetate as an activating agent. The activated carbon exhibits high adsorption capacities for CO2 and CH4, with selectivity values that enable effective separation. Additionally, the study finds that the CO2 emissions produced during activated carbon synthesis can be easily neutralized through their use in small biogas production units.

Summary: In this study, the biological activity of two underexplored spider venom peptides (J-atracotoxin-Hv1c and mu-theraphotoxin-Hhn2b) against adult D. suzukii flies was assessed, as well as the biological response of flies to these peptides through detoxification mechanisms. Results demonstrate that mu-theraphotoxin-Hhn2b enhanced fly longevity. Gene expression analysis suggests that detoxification and stress-related mechanisms are triggered in D. suzukii flies in response to treatment with these peptides. Our results highlight the potential of venom peptides to control D. suzukii and how to ultimately devise improved target-specific formulations.

Summary: Agricultural systems require low-cost, safe antibiotics to protect crops from pests and diseases. Peptaibiotics have shown potential as alternatives to agrochemicals, with antibacterial, antifungal, and antiviral activity, and the ability to induce plant resistance against phytopathogens. However, their low solubility and difficulty in synthesis and purification have limited their application in agriculture. This review provides a comprehensive analysis of peptaibiotics, including their classification, biosynthesis, relevance to plant protection, and mode of action against phytopathogens, as well as strategies to enhance their solubility and production.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
