This review outlines the current state of freeze-dried platelet-rich plasma (FD-PRP) research, emphasizing its use in wound healing, lumbar fusion, knee conditions, and dentistry, but reports no new clinical findings.

In this study, researchers developed a novel bio-patch from decellularized freeze-dried tumor tissues and hair melanin nanoparticles, which demonstrated enhanced wound healing in vivo by reducing oxidative stress, suppressing inflammation, and promoting angiogenesis.

The researchers reported that freeze-dried collagen-activated platelet-rich plasma increased transforming growth factor-β1 levels compared to non freeze-dried PRP with collagen, suggesting a potential benefit for tissue regeneration.

This study explored the use of dexamethasone-loaded polymer hybrid nanoparticles in a xanthan gum hydrogel for treating alopecia areata, finding that freeze drying with sucrose influenced particle size, release, and permeation, but had no impact on cytotoxicity or anti-inflammatory efficacy in human keratinocytes.

This study developed a multifunctional core-shell fiber dressing that preserves platelet-rich plasma for 180 days, facilitating sustained growth factor release and improved wound healing.

This study found that porcine platelet-rich plasma can be a commercially viable replacement for fetal bovine serum with similar effectiveness in promoting human hair follicle cell growth.

This review highlights that synthetic biodegradable polymers like PVA, PCL, PLA, PLGA, PU, and PEO/PEG can address the limitations of natural polymers in wound healing, offering improved mechanical properties and slower degradation, thereby enhancing their application as wound dressings.

The document concludes that hair keratin-chitosan scaffolds were successfully made and are suitable for biomedical use.

This study developed a composite product from decellularized human placental connective tissue matrix and placental extract, finding that the combination showed improved biochemical and mechanical properties compared to each component alone, suggesting its potential use for treating chronic and deeper wounds.

This study developed a multifunctional bilayer dressing containing nanosilver and basic fibroblast growth factor, which improved wound healing by preventing bacterial penetration, promoting angiogenesis and hemostasis, and accelerating cell proliferation and migration, outperforming a control group by increasing healing rates by 47% in vivo.

This study found that freeze-dried homologous platelet-rich plasma (FD HPRP) increased osteocalcin levels in cultured osteoblasts, suggesting its potential to support bone regeneration in periodontal treatment.

This review discusses the use of inorganic-based biomaterials for hemostasis and wound healing, including various preparation methods and mechanisms, but reports no new clinical results.

This work explores using a liquid crystalline phase to stabilize benzoyl peroxide nanosuspensions, suggesting a promising method to potentially reduce the side effects of acne treatments.

In this study, dry powder inhalers containing Cepharanthine were administered to rats with acute lung injury, significantly reducing pulmonary edema, hemorrhage, and inflammatory markers, suggesting its potential as an effective anti-inflammatory treatment when inhaled directly into the lungs.

This study used novel methods to detect and map iodine concentrations in pig skin, finding iodine present in the coating, stratum corneum, and tissue around hair follicles.

This study evaluated new aqueous gel formulations of minoxidil without irritants and found that the calcium alginate gel showed the best performance in terms of drug release and skin permeation.

This study developed a biodegradable gelatin and chitosan hemostatic sponge, enhanced with pomegranate peel extract, for dental applications, highlighting its effective antibacterial properties, improved blood absorption, and reduced clotting time, suggesting potential for use in clinical dental and wound care procedures.

This study confirmed that porcine platelet-rich plasma could commercially replace fetal bovine serum due to its higher growth factor levels and effectiveness as a hair growth promoter comparable to existing serum.
