The pharmaceutical application of biomaterials has attained a great success. Rapid wound healing is an important goal for many researchers. Hence, this work deals with the development of nanocellulose crystals/lipid nanogels loaded with ofloxacin (OFX) to promote skin repair while inhibiting bacterial infection. Ofloxacin-loaded hybridized nanocellulose/lipid nanogels (OFX-HNCNs) were prepared and evaluated adopting a computational method based on regression analysis. The optimized nanogels (OFX-HNCN7) showed a spherical outline with an encapsulation efficiency (EE), particle size (PS) and zeta potential (ZP) values of 97.53 ± 1.56%, 200.2 ± 6.74 nm and -26.4 ± 0.50 mV, respectively, with an extended drug release profile. DSC examination of OFX-HNCN7 proved the amorphization of the encapsulated drug into the prepared OFX-HNCNs. Microbiological studies showed the prolonged inhibition of bacterial growth by OFX-HNCN7 compared to the free drug. The cytocompatibility of OFX-HNCN7 was proved by Sulforhodamine B assay. Tissue repair was evaluated using the epidermal scratch assay based on cell migration in human skin fibroblast cell line, and the results depicted that cell treated with OFX-HNCN7 showed a faster and more efficient healing compared to the control. In overall, the obtained findings emphasize the benefits of using the eco-friendly bioactive nanocellulose, hybridized with lipid, to prepare a nanocarrier for skin repair.
Dog bites are one of the most common injuries in the United States, with varying presentations such as avulsion injuries and lacerations, and they range from a single bite to multiple bites in a victim. The severity of the dog bite is often the biggest factor in determining the treatment course. This report discusses the treatment of a 60-year-old male with severe facial avulsion trauma from a dog bite.
Ethnopharmacological Relevance: Diabetic ulcer is a serious diabetes complication and a primary reason for amputations. For many years, the San Huang Xiao Yan (SHXY) recipe has served as a conventional remedy for these ulcers, effectively reducing inflammatory factors and exhibiting considerable therapeutic efficacy. However, the precise mechanism remains incompletely understood.
Background: The utilization of PD1 and CTLA4 inhibitors has revolutionized the treatment of malignant melanoma (MM). However, resistance to targeted and immune-checkpoint-based therapies still poses a significant problem.
Objective: Here, we mine large-scale MM proteogenomic data to identify druggable targets and forecast treatment efficacy and resistance.
Bacterial infections can lead to severe complications that adversely affect wound healing. Thus, the development of effective wound dressings has become a major focus in the biomedical field, as current solutions remain insufficient for treating complex, particularly chronic wounds. Designing an optimal environment for healing and tissue regeneration is essential.
Background: NeoDura (Medprin Biotech Gmbh) is an absorbable dural repair patch consisting of degradable poly-L-lactic acid and porcine gelatin that provides a hermetic closure of the dura mater (Medprin Biotech. Neodura. Dural Repair Patch [Brochure].
