Assessment of wound healing efficacy of Growth Factor Concentrate (GFC) in non-diabetic and diabetic Sprague Dawley rats

Advanced Bioinspired Silver Nanoparticles Integrated into Polyherbal Gel for Enhanced Diabetic Foot Ulcer Regeneration

Diabetic foot ulcers (DFUs) are a severe diabetic complication, frequently resulting in infections and amputations. The current research focuses on the development and assessment of a synergistic nano-herbal formulation based on green-synthesized silver nanoparticles and a polyherbal gel for the efficient treatment of DFUs. Silver nanoparticles (AgNPs) were green-synthesized using aqueous extracts of Tagetes erecta (Marigold) and Portulaca oleracea (Purslane). They were further blended with a polyherbal gel formulation to improve antimicrobial and wound-healing activities. AgNPs were synthesized using aqueous plant extracts and characterized through UV-Visible spectrophotometry (SPR peaks: 439 nm for T. erecta, 427 nm for P. oleracea), FT-IR (O-H stretching at 3610 cm⁻1, 3687 cm⁻1), XRD (semi-crystalline structure), and DLS (particle sizes: 311 nm and 304 nm, zeta potentials: -19.7 mV and -20.1 mV, respectively). Antimicrobial studies showed strong inhibition against S. aureus (21 mm, 20 mm) and K. pneumoniae (22 mm) for AgNPs. The polyherbal gel, incorporating extracts of Ficus racemosa, Emblica officinalis, Curcuma longa, Carica papaya, Terminalia bellerica, Acacia catechu, and Aloe vera, achieved 85% wound closure in diabetic rats by day 16, compared to 60% (untreated) and 95% (povidone iodine). AgNP-antibiotic combinations reached 90% healing. HbA1c levels remained unchanged, indicating glucose-independent healing. These findings suggest that AgNP-polyherbal formulations could serve as a sustainable and effective DFU treatment, enhancing antimicrobial activity and promoting tissue regeneration.

Recent advances in sodium alginate-based dressings for targeted drug delivery in the context of diabetic wound healing

Diabetic wounds pose a significant challenge in healthcare due to impaired healing and increased risk of complications. In recent years, various drug delivery systems with stimuli-responsive features have been developed to address these issues. These systems enable precise dosage control and tailored drug release, promoting comprehensive tissue repair and regeneration. This review explores targeted therapeutic agents, such as carboxymethyl chitosan-alginate hydrogel formulations, nanofiber mats, and core-shell nanostructures, for diabetic wound healing. Additionally, the integration of nanotechnology and multifunctional biomimetic scaffolds shows promise in enhancing wound healing outcomes. Future research should focus on optimizing the design, materials, and printing parameters of 3D-bio-printed wound dressings, as well as exploring combined strategies involving the simultaneous release of antibiotics and nitric oxide for improved wound healing.

A Prospective Multicenter Study to Evaluate the Safety and Efficacy of the Topical Application of MYOWNN™, an Autologous Growth Factor Concentrate (AGFC) Serum, in Anti-Aging

Background

Growth factors from platelets have been emerging as a revolutionary treatment with the ability to induce cell growth in the skin, which results in retarding and reversing the aging process. Platelet-rich plasma (PRP) allows for greater release of growth factors and biologically active proteins, which in turn activates the cascade of stimulation of neoangiogenesis and collagen production. PRP is used in anti-aging and facial skin rejuvenation in the form of dermal injections and topical application during micro-needling. This study was conducted to assess the safety and efficacy of a topically applied face serum, MYOWNN™ (Wockhardt Ltd., Mumbai, India). MYOWNN™ is an autologous growth factor concentrate that has been made into a topical face serum.

Methods

Male and female subjects in the age group between 30 and 55 years (both inclusive) with Fitzpatrick skin type III-V who had not taken any oral or topical treatments for at least four weeks before and any platelet-rich plasma (PRP) based facial treatment (injections) at least six months before the study entry were included. MYOWNN™ serum was applied on the face once daily at night, approximately 30 minutes before sleeping preferably, for a total duration of five months. Six parameters, i.e. spots, pores, wrinkles, texture, moisture, and pigmentation, were evaluated at regular intervals with Visage-LS (dermaindia®, Tamil Nadu, India), a face analysis system that gives the live status of these six parameters and is an advanced live status skin detection equipment together with shooting, analyzing, and displaying functions, as well as the subjective analysis, was performed by subjects and physicians using different globally accepted scales like physician’s global aesthetic improvement scale (PGAIS), subject’s global aesthetic improvement scale (SGAIS), subject satisfaction score (SSS), and wrinkle severity rating scale (WSRS). For analysis, a mixed model for repeated measures was used. The model had change from baseline as the dependent variable visit as a factor and baseline assessment result as a covariate. All primary and secondary efficacy endpoints were analyzed using Modified Intent-to-Treat (mITT) populations.

Results

Improvement in an average of six anti-aging parameters was observed as early as three months while statistically significant improvement was observed by the end of five months of application. A statistically significant improvement in wrinkles was observed by the end of three months of the application itself. There were no product-related adverse events reported.

Conclusions

Five months of application of MYOWNN™ serum showed a statistically significant improvement in an average of six parameters of anti-aging and face rejuvenation with a p-value of 0.0150 (<5% level of significance (i.e. 0.05) and was also well-tolerated.
