This field has made significant advances in recent years, particularly in the use of stem cells and biomaterials. Advancements in cell-based therapies have involved the use of cells to repair or replace damaged tissues and organs. Tissue engineering involves using scaffolds and growth factors to promote tissue regeneration. However, a major challenge in this field is the formation of adhesions, which can cause complications, such as intestinal obstruction and chronic pain. Adhesion barriers are used to prevent adhesion of tissues and organs during recovery, thereby reducing the risk of complications. Anti-adhesion materials, such as polysaccharides, proteins, and synthetic polymers, are used to create a physical barrier between tissues and prevent adhesion. These materials can be used alone or in combination, but their effectiveness varies.

The skin is a vital organ that functions as a barrier to protect the body from external substances. In recent years, there has been a growing emphasis on skin treatment research. Hyaluronic acids (HAs) are commonly used in cosmetic and drug formulations to regulate excessive skin cornification, making them promising candidates for acne treatment. The introduction of HAs in dermatology has revolutionized the field of skin care, and they are used to treat various skin disorders, such as acne, ichthyosis, keratoses, warts, psoriasis, and photoaged skin. The antiaging benefits of HA have gained considerable attention in cosmetic dermatology, resulting in a surge in cosmetic products and skin care systems that contain HA. The study found that AHA-BHA-infused nanofiber skin masks are effective in treating acne vulgaris. The nanofiber masks were found to reduce inflammation, sebum production, and acne lesions. The study suggests that AHA-BHA-infused nanofiber skin masks could be a promising topical treatment for acne vulgaris.

Nanotechnology involves manipulating nanoscale materials to create nanoparticles that can penetrate the skin and deliver active ingredients more effectively. Natural products are commonly used in cosmetics because of their therapeutic properties and minimal side effects; however, the safety of nanoparticles in cosmetic products is a concern that requires further research. Chronic and nonhealing wounds pose a significant threat to patients' lives, and there is a pressing need for novel materials and approaches to wound healing. Nanomaterials exhibit unique physicochemical properties owing to their distinct structures, resulting in small size, surface, and macroscopic quantum tunnelling effects, making them ideal for use in wound dressings. Herbal transdermal patches offer advantages such as better patient tolerance, minimal side effects, renewable sources of medication, extensive availability, and costeffectiveness; however, they also have disadvantages such as slower growth in demand, testing difficulties, and limited availability. This article concludes that by following a regimen that includes both natural ingredients and over-the-counter treatments, consumers can improve their skin health and appearance.

The incorporation of DOX into the pullulan solution was carried out to take advantage of Pullulan's biocompatibility, biodegradability and hydrophilic nature. The hydrophilic nature of PVA can result in rapid drug release, while the hydrophobic nature of PDMS allows for slower drug release. The use of PVA-PDMS polymers together in the shell offers an initial rapid release followed by a prolonged and controlled drug release. This combination is superior to PVA or PDMS in terms of safety, mechanical strength, flexibility, controlled drug release and structural stability. This innovative composite system was designed to optimise DOX's controlled release to increase its therapeutic efficacy and reduce systemic toxicity. The kinetics of the drug release was characterised by an initial burst release followed by a sustained release phase, allowing controlled and prolonged release of the chemotherapeutic agent. Our results indicate that the pullulan/PVA-PDMS composite is a promising candidate for practical drug delivery applications, especially in cancer therapy.

The combination of these biopolymers aims to optimize the scaffold properties for cell growth, viability, and tissue regeneration. Materials and Methods: Pullulan, Collagen, and Pullulan/Collagen composite nanofibers were fabricated using electrospinning. The fibers were characterized using scanning electron microscopy (SEM) to determine the fiber diameter, and Fourier-transform infrared spectroscopy (FTIR) was employed to assess the molecular interactions. Cell viability was evaluated using MSCs cultured on the scaffolds and apoptosis assays were conducted to assess cell health. Distilled water was used as the solvent to maximize biocompatibility. Results: SEM analysis revealed that Pullulan nanofibers exhibited a larger average diameter (274 ± 20 nm) compared to Collagen fibers (167.03 ± 40.04 nm), while the Pullulan/Collagen composite fibers averaged 280 ± 102 nm. FTIR confirmed the molecular interactions between Pullulan and Collagen. Regarding biocompatibility, the Pullulan/Collagen scaffold demonstrated superior cell viability at 99% compared to 91% for Pullulan alone. Apoptosis assays indicated significantly lower necrosis rates for the composite scaffold (1.29%) than for the Pullulan-only scaffolds (2.35%). Conclusion: Using distilled water as a solvent was critical in increasing cell viability and facilitating the healthy proliferation of MSCs without cellular damage. Additionally, the reduced platelet activation and macrophage activity (0.75-fold for both) further supported the biocompatibility of the Pullulan/Collagen scaffold, demonstrating its potential for tissue engineering and chronic wound healing applications.

Hydroxy acids, such as alpha-hydroxy acids (AHA) and beta-hydroxy acids (BHA), have demonstrated potential as effective ingredients for topical acne treatments due to their exfoliating and skin-rejuvenating properties. This study assessed the effectiveness of encapsulating AHA and BHA in pullulan-collagen nanofibers as a novel approach to acne treatment. The study involved preparing Pullulan and polyvinyl alcohol (PVA) solutions combined with sodium chloride (NaCl) to create a stable mixture.
