In this study, a dental membrane scaffold was fabricated using a 3D printing technique, and the antimicrobial effect of pomegranate seed and peel extract were investigated. For the production of the dental membrane scaffold, a combination of polyvinyl alcohol, starch, and pomegranate seed and peel extracts was used. The aim of the scaffold was to cover the damaged area and aid in the healing process. This can be achieved due to the high antimicrobial and antioxidant content of pomegranate seed and peel extracts (PPE: PSE). Moreover, the addition of starch and PPE: PSE improved the biocompatibility of the scaffold, and their biocompatibility was tested using human gingival fibroblast (HGF) cells. The addition of PPE: PSE into the scaffolds resulted in a significant antimicrobial effect on S. aureus and E. faecalis bacteria. Moreover, different concentrations of starch (1%, 2%, 3% w/v) and pomegranate peel and seed extract (3%, 5%, 7%, 9%, and 11% PE v/v) were analyzed to obtain the ideal dental membrane structure. The optimum starch concentration was chosen as 2% w/v due to it giving the scaffold the highest mechanical tensile strength (23.8607 ± 4.0796 MPa). The pore sizes of each scaffold were studied by SEM analysis, and pore sizes were arranged between 155.86 and 280.96 μm without any plugging problems. Pomegranate seed and peel extracts were obtained by applying the standard extraction method. High-performance liquid chromatography was performed using the diode-array detection (HPLC-DAD) technique to analyze the phenolic content of the pomegranate seed and peel extracts. Two phenolic components of the pomegranate seed and peel extracts were investigated in the following amounts: fumaric acid (17.56 μg analyte/mg extract) and quinic acid (18.79 μg analyte/mg extract) in pomegranate seed extract and fumaric acid (26.95 μg analyte/mg extract) and quinic acid (33.79 μg analyte/mg extract) in pomegranate peel extract.

Spirulina platensis, well-known for its abundant nutrients and sustainability, shows potential as a microcarrier for various biotechnological uses. However, its natural degradability presents a challenge. Polylactic Acid (PLA) offers a solution due to its biodegradability and compatibility. By using the electrohydrodynamic atomization technique (electrospraying), precise control over microparticle characteristics like size, shape, and composition is achieved by adjusting parameters such as voltage, flow rate, and solution properties. In this research, microparticles made from Spirulina extract and PLA were created through electrospraying to act as microcarriers. Different formulations were tested, including 3% PLA and blends of Spirulina extract and PLA at concentrations of 0.125%, 0.25%, and 0.5% using chloroform and ethanol in the ratio of 19:1. Through various tests (MTT assay and colony formation test) the biocompatibility of producing microparticles was assessed using HUVEC and HaCaT cell lines, indicating these microparticles' potential for diverse applications as microcarrier systems.

Pancreatic cancer is one of the most lethal malignancies, characterized by late diagnosis, rapid progression, and resistance to conventional therapies. The oncogenic microRNA miR‐21 is frequently upregulated in pancreatic tumors and contributes to tumor growth, migration, and chemoresistance by targeting tumor suppressor genes. Lycopene, a naturally occurring carotenoid with antioxidant and anti‐inflammatory properties, has shown promise as a chemopreventive agent in several cancer types. This study investigates the therapeutic potential of lycopene in human pancreatic cancer cell lines (PANC‐1 and MIA PaCa‐2) and their miR‐21 knockout counterparts. Treatment with 50 μM lycopene significantly reduced cell viability, colony formation, migration, and spheroid integrity and decreased intracellular reactive oxygen species (ROS) levels, with more pronounced effects in miR‐21‐deficient cells. These findings highlight the role of miR‐21 in modulating lycopene sensitivity and support the potential of lycopene as an adjunctive therapeutic agent in pancreatic cancer.

Cellular metabolism is a key regulator of tissue repair and regeneration, with mitochondrial function playing a central role in energy production and cellular homeostasis. Dysfunctional mitochondria, often due to excessive reactive oxygen species (ROS), contribute to oxidative stress, impaired wound healing, and chronic inflammation. This study investigates the therapeutic potential of DeepA‐I, a Boron‐enriched compound, in enhancing mitochondrial health, reducing oxidative damage, and promoting cellular repair in human umbilical vein endothelial cells (HUVEC) and mouse embryonic fibroblasts (MEF). Boron quantification via inductively coupled plasma optical emission spectroscopy (ICP‐OES) confirmed its presence in DeepA‐I. Cytotoxicity assessment (MTT assay) demonstrated its safety, while fluorescence microscopy (DAPI, MitoSPY, DCFDA) revealed reduced ROS levels and preserved mitochondrial integrity. A scratch assay showed accelerated cell migration and wound closure in DeepA‐I‐treated cells. Western blot analysis indicated the downregulation of Akt (a proliferation marker) and the upregulation of NRF2, a key regulator of oxidative stress resistance, without affecting apoptosis‐related proteins. These results suggest that DeepA‐I, via its Boron‐mediated mechanisms, enhances mitochondrial function, mitigates ROS‐induced damage, and improves tissue repair, positioning it as a promising therapeutic candidate for inflammatory and degenerative conditions.
