Summary: Amphiphilic polysaccharides were fabricated by coupling hydrophobic PFPA to hydrophilic alginic acid, and their resistance against protein adsorption and marine fouling organisms was explored. The amphiphilic multilayers exhibited higher resistance towards protein adsorption and microfouling marine organisms compared to multilayers without fluoroalkyl groups.

Summary: Microbial colonization of surfaces is a significant problem in many applications, leading to contamination and infections. This study aimed to investigate novel technologies to prevent biofilm formation on surfaces. Glass surfaces were coated with melanin-ZnO2, melanin-TiO2, and TiO2 hybrid nanoparticles using cold plasma activation. The antibiofilm properties were quantitatively characterized using Pseudomonas fluorescens AR 11 as a model organism. The results showed that the proposed surface coatings effectively prevented biofilm formation, with melanin-TiO2 demonstrating the highest efficiency. This research provides valuable support for future implementation of this technique in various applications.

Summary: This study aims to precisely control the coating oxygen permeability through layer-by-layer (LbL) assembly using chitosan and sodium alginate. The coating assembly was driven by electrostatic interaction, and the fastest growth was achieved at a pH of 4 for both SA and CS and a NaCl concentration of 0.1 mol/L. The optimized LbL coating extended the shelf life of strawberries, tangerines, and bananas by 2, 4, and 4 days, respectively.

Summary: The study evaluates the antimicrobial efficacy of chitosan-based coatings to prevent implant-associated infections, finding that associations with enzymes, antimicrobial peptides, and polymers enhance the antimicrobial and anti-adhesive properties of chitosan. This extends its potential use in physiological conditions and offers promising developments for implantable medical devices.

Summary: This study investigated the anti-biofilm activity of coatings applied on stainless steel commonly used in the food industry. The results showed that coatings consisting of APTES with either TEOS or AA effectively reduced the biofilm formation of Listeria monocytogenes. The physical and chemical characteristics of the coatings, such as surface roughness and hydrophilicity, were found to influence their anti-biofilm activity.

Summary: CAUTIs, caused by biofilms, are a common healthcare-associated infection. The use of antibacterial zinc oxide nanoparticles (ZnO NPs) decorated with amylase enzyme (AM) on silicone urinary catheters effectively inhibited biofilm formation of bacteria in vitro and in vivo, showing promise for prevention and control of CAUTIs.

Summary: The study shows that bone marrow mesenchymal stem cells (BM-MSCs) respond better to extracellular matrices (ECMs) produced by young BM cells, promoting their proliferation and responsiveness to growth factors. The study also found that decreased levels of Cyr61 protein in bone tissue of elderly individuals are associated with low bone mineral density. These results demonstrate the importance of Cyr61 in the BM-MSC niche and suggest potential therapeutic targets for age-related bone loss.

Summary: Salivary gland dysfunction can cause severe oral and systemic diseases and compromise quality of life. Current treatments are palliative, but transplantation of allogeneic cells and the use of mesenchymal stem cells (MSCs) show promising potential for restoring saliva production. However, recent findings suggest that allogeneic MSCs may not be immune-privileged after transplantation, whereas autologous MSCs could be a viable solution. Advances in in vitro expansion of autologous MSCs on tissue-specific matrices offer a new therapeutic approach for restoring SG function.

Summary: Oral health is crucial for the quality of life and overall well-being of the aging population. This study analyzed the oral health and microbiota of marmosets to understand the changes in oral health during human aging. The findings suggest that changes in the oral microbiome are associated with a decline in oral health in aging marmosets.
