BBD shows the best values obtained are the solvent ratio of 11.5%, gelatin concentration of 22%, and voltage of 20 kV which were validated by an experimental assay. The results showed that the positively charged ionic groups present on the surface of gelatin adsorbed the carboxyl groups in GLT and the magnetic fields created by their nucleus influenced each other. Finally, GLT nanofibers with an average size distribution of 75.4 nm were observed. The result showed an efficiency of 75% for drug entrapment. The release kinetics demonstrated a sustained release of GLT follows the Korsmeyer-Peppas model that suggests a combination of surface drug dissolution and quasi-Fickian diffusion. Also, GLT nanofibers showed a higher cytotoxic activity against MCF-7 cell lines than free GLT.

Field emission electron microscopy (FE-SEM), fourier transform infrared spectroscopy (FTIR), moisture management properties, tensile properties, antibacterial activity, and wound healing assessment of the fabricated hybrid bio-nano scaffolds were employed to investigate the different properties of hybrid bio-nano scaffolds. The results exhibit that the sample with Col (50%) and Ns (25%), Cs (25%) has good fiber formation with a mean diameter of 381 ± 22 nm. This bio-nano scaffold has a porosity of 78 ± 6.9% and a fast absorbing-slow drying nature for providing a moist environment. The antibacterial zones of inhibition (ZOI) against Staphylococcus aureus and Escherichia coli were 10 ± 1.3 and 8 ± 0.9 mm respectively, and appeared to be adequate to inhibit bacterial action. The wound healing assessment states that 84 ± 3.8% of wound closure occurs in just 10 days, which is quicker (1.5 times) than the duration of a commercial bandage.

In the present work, a mixed polymeric nanomicellar formulation composed of bioactive Pluronic P123, Pluronic F68, and biocompatible phosphatidylcholine (PC) was designed and examined as the nanovehicles for overcoming the major barriers of poor bioavailability related to CUR. The CUR-incorporated P123/F68/PC mixed nanomicellar formulation (CUR-PFPC) was fabricated by the thin film technique and investigated in vitro. The fabrication of CUR-PFPC was optimized through D-optimal design. CUR-PFPC morphology, size distribution, zeta potential, drug encapsulating and incorporation efficiency, compatibility, and crystallinity were characterized using DLS, TEM, FTIR, XRD, and DSC analysis. Moreover, the cumulative drug release, antioxidant assays, and antimicrobial properties of formulations were also examined. The CUR-PFPC formulation exhibited a micellar size of 67.43 nm, a zeta potential of −15.1 mV, a PDI of 0.528, and a spherical shape. The mixed micellar formulation showed excellent compatibility and stability. The in vitro release profile of the CUR-PFPC reached over 60% in comparison to the 95% release of CUR, indicating a slow and sustained release. The DPPH assay showed that the CUR-PFPC had 96% antioxidant activity. Results show that the CUR-PFPC has powerful antibacterial and antifungal properties, which separates it from the free CUR. These findings suggest that the fabricated CUR-PFPC mixed polymeric nanomicellar formulation is thermodynamically and kinetically stable and may be considered a novel nanovehicle for hydrophobic antimicrobial drugs like CUR.

The most common plasticizer is PEG to obtain polymer-based biomaterials. On the other hand, triacetin is a non-toxic, FDA-approved plasticizer mostly used in the food industry. In this study, we used triacetin as a plasticizer to obtain hydrophobic membranes for the prevention of intra-abdominal adhesion. We selected a well-known polymer named PHBHHx which is a bacterial polyester generally used as supporting material for cell attachments in regenerative tissue applications. We evaluated the triacetin as a plasticizer and its effect on mechanical, thermal, surface area, pore size, and surface energy. The hydrophobic/hydrophilic contrast of a biomaterial surface determines the biological response. Surface hydrophobicity is critical for the cellular response. The contact angle tests of PHBHHx revealed that the hydrophilicity of the membrane was decreased following triacetin blending. Modification of the PHBHHx membrane by blending with triacetin caused a significant decrease in cell adhesion. The cell attachment rates of PHBHHx membranes were as 95 ± 5% on the first day, 34.5 ± 0.9% on third day, and 23 ± 1.5% on the fifth day, respectively. The rates of cell attachments on PHBHHx/triacetin membranes were determined as 79 ± 2.5% for the first day, 33 ± 2.7% for the third day, and 13 ± 2.1% for the fifth day, respectively. Besides, triacetin blending decreased the surface area from 38.790 to 32.379 m2/g. The elongation at breaks was observed as 128% for PHBHHx and 171% for PHBHHx/triacetin.

The PEC hydrogel scaffold’s chemical, physical, and mechanical characterizations were performed with FTIR, DSC, DMA, and Micro-CT analyses. In order to develop an in vitro BBB model, the human neuroblastoma cell line (SH-SY5Y) and mouse astrocyte cell line (C8-D1A) were mixed into a hydrogel, which is the abluminal side of the BBB. Human microvascular endothelial cells (HBEC-5i) were seeded on the hydrogel, and it was aimed to mimic the luminal side of the BBB. The characterization of the BBB model was determined by measuring the TEER, observation of the cell morphology with SEM, performing the permeability of Lucifer Yellow, and observation of tight junction proteins with immunofluorescence staining. As a result, HBEC-5i cells expressed tight junction proteins (ZO-1 and Claudin-5), showed TEER of 340 ± 22 Ω.cm2, and the Lucifer Yellow permeability of 7.4 × 10−7 ± 2.7 × 10−7 cm/s, which was suitable for use as an in vitro BBB model.

Natural rubber latex (NRL) being the first choice for the manufacture of several conventional biomedical devices, it is essential to ensure the surfaces of the same are inherently inactive against most microorganisms. This study presents NRL film surface conjugated with a well-known antibiotic, gentamicin through an amide linkage to generate antibacterial activity to the surface with a significant growth inhibition rate, especially against Staphylococcus aureus. The NRL films were surface-oxidized under controlled acidic conditions to generate carboxyl groups exploring the unsaturation of the base monomer unit. The carboxyl group reacts with the amine groups of gentamicin facilitating its surface conjugation. The surface anchoring was authenticated by FTIR-ATR complimented further by contact angle measurement as a function of hydrophilicity and elemental analysis by EDX spectroscopy. The antibacterial efficacy of modified NRL films was evaluated using antibacterial drop test and the results indicated a substantial growth inhibition rate (>60%) against Pseudomonas aeruginosa and Staphylococcus aureus. The study could be further optimized and proposed as a viable route for the conjugation of active molecules over inert polymer molecules.","PeriodicalId":15038,"journal":{"name":"Journal of Bioactive and Compatible Polymers","volume":"23 1","pages":"220 - 233"},"PeriodicalIF":1.7,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76718169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chitosan/gelatin (Cs/Gel) composites are among the most known scaffolds with structural similarity to bone matrix and a high potential to support cell attachment and proliferation. Recently, plant-derived phenolic compound apigenin has been identified to direct the osteogenic differentiation of mesenchymal stem cells and retain osteoblast metabolic functions. We incorporated apigenin into Cs/Gel membranes to improve apigenin bioavailability and get proper concentrations for efficient biological activities. Apigenin-loaded Cs/Gel membranes were prepared using a solution casting method with various apigenin contents (0, 10, 25, 50, and 100 µM). Chemical composition, morphological characteristics, swelling behavior, degradation rate, and apigenin release from membranes were evaluated. Saos-2 osteoblasts were cultured on membranes to investigate cell-membrane interaction, proliferation, viability, and mineralization under the osteogenic culture condition. The results showed that membranes had homogeneous and moderate rough surfaces, facilitating osteoblast attachment and expansion. Swelling ratios exceeded 200%, reaching a stable rate in 24 h. Apigenin-loaded membranes degraded slower in vitro. Membranes containing lower apigenin concentrations exhibited a higher cargo release profile over 21 days. Apigenin improved osteoblast proliferation and viability, but the mineralization depended on apigenin dose, with optimized values at low concentrations. These data suggested that Cs/Gel membranes loaded with low apigenin contents improved osteoblast survival, proliferation, and mineralization.","PeriodicalId":15038,"journal":{"name":"Journal of Bioactive and Compatible Polymers","volume":"105 1","pages":"142 - 157"},"PeriodicalIF":1.7,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91028561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Less toxic, but effective treatments are sought after. Aloe vera (barbadensis miller), known for its beneficial properties, has been studied for cancer treatment. While aloe gel has been shown to exhibit anti-cancer activity, it cannot form a hydrogel alone. Therefore, an interpenetrating network comprising alginate blended with aloe was examined as a cervical cancer treatment. We hypothesized the antioxidant properties of aloe gel would decrease cancer cell viability while the alginate hydrogel would improve mucoadhesion. We further hypothesized the antioxidant activity of aloe gel would induce cancer cell death at levels similar to common chemotherapeutics, and aimed to determine if these chemotherapeutic behaviors are constructive or destructive. Material and adhesive properties, drug encapsulation, and cancer cell viability were investigated and validated. The effect of aloe-alginate hydrogels on cervical cancer cell viability was not significantly different compared to aloe-blends containing doxorubicin (DOX), indicating that the aloe alone decreased cancer cell viability rendering the additional cytotoxic therapeutic not impactful as an adjuvant therapy. This study provides insight into the potential of natural biopolymers for treating cervical cancer without systemic toxic compounds.","PeriodicalId":15038,"journal":{"name":"Journal of Bioactive and Compatible Polymers","volume":"29 1","pages":"158 - 177"},"PeriodicalIF":1.7,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87326096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
