This study found that high levels of parathyroid hormone-related protein expression can result in the production of shorter hair shafts, likely through effects on angiogenesis.

This laboratory study found that PI extract, along with its metabolites Ang and Mac, inhibited cell proliferation and protein expression linked to pathways involved in BPH, suggesting potential for therapeutic use, although the Ang-Mac combination showed no significant effect on apoptosis through the p53 pathway.

Postinflammatory hyperpigmentation causes dark skin patches and needs personalized treatment.

This study identified the genes for pyochelin siderophore biosynthesis as a novel target regulated by the heme-responsive PrrH sRNA in Pseudomonas aeruginosa.

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.

In this study, clinically used preoperative skin preparations with povidone iodine and chlorhexidine gluconate did not meet FDA log-reduction standards for bacterial bioburden in a porcine model, suggesting persistent infection risks.

This review discusses the use of platelet-rich plasma (PRP) in regenerative plastic surgery and dermatology for hair regrowth and skin revitalization, noting some potential side effects without reporting new clinical results.

In this pilot study, PDLLA scalp microinjections showed improvement in physician-rated Global Aesthetic Improvement Scale scores over 12-24 weeks for 90% of patients with non-scarring alopecia, with no serious adverse events reported, although findings remain preliminary due to methodological limitations.

This study found that a new SIS-PEG sponge promoted rapid skin defect healing in mice and showed potential for reconstructing reconstituted skin with regenerated hair.

This review discusses the therapeutic properties of polydeoxyribonucleotides derived from marine organisms for wound healing and inflammation, but it reports no new clinical results.

This study developed the CATNIP computational model, which uses biological and chemical information to successfully identify drug repurposing opportunities for various conditions, including Parkinson’s disease and Type 2 Diabetes.

This chapter provides dermatology trainees with insights on managing lichen planopilaris, emphasizing treating active disease to prevent further hair loss and recommending a tapered course of oral steroids for disease stabilization.

This study found that downregulating PI3K in common bean severely impaired symbiosis with beneficial microorganisms, indicating an essential role for autophagy-related processes in these mutualistic interactions.

In this pilot study, researchers observed a correlation between clinical severity and histologic severity of lichen planopilaris, suggesting that an immunohistochemical scoring system could aid in grading disease activity.

This case report challenges the traditional view by documenting reversible vision loss following scalp injections of platelet-rich plasma, attributed to an inflammatory or microvascular event, treatable with corticosteroids.

This study found that in patients with elevated fibrinogen levels undergoing revision rhinoplasty, PDRN decreased M1 cytokines and increased M2 cytokines, potentially offering a new therapeutic approach, but further research is needed to understand its mechanisms and effects fully.

The authors concluded that controlling voltage, pulse width, and calcium concentration in pulse electric field-activated platelet-rich plasma enhances the release of growth factors and serotonin without causing clot formation, suggesting potential clinical advantages over bovine thrombin-activated PRP.

This review discusses the antibacterial properties of platelet-rich plasma (PRP) and summarizes existing preclinical and clinical research on its use for preventing and treating wound and bone infections, but presents no novel data.

PRP treatment improved skin pigmentation and appearance in facial lichen planus pigmentosus.

This paper discusses the recent online debate over the use of PRP in hair restoration but provides no new findings.

This study confirmed porcine PRP's commercial viability as a fetal bovine serum replacement, showing higher growth factor levels and stability, without increasing human follicle dermal papilla cell proliferation compared to FBS.

This study observed that disrupting the Pnkp gene in adult mice resulted in a premature aging-like phenotype, suggesting PNKP's vital role in maintaining normal growth and survival of certain progenitor cell populations.

This review highlights the positive effects of platelet-rich plasma in aesthetic and regenerative medicine, particularly for skin rejuvenation, anti-aging, hair reconstruction, and wound healing, but it reports no new clinical results.

PRP therapy at Ethos Spa improves hair growth and quality with minimal maintenance.

This study found that inhibiting DPP4 during a critical period post-wounding increases hair follicle regeneration and Wnt signaling in large skin wounds.

This study observed that PAI-2 is consistently expressed in differentiating cells of murine hair and nail, suggesting it may function as a marker of differentiation and possibly protect against premature cell death.

This study found that substance P and calcitonin-gene-related peptide have different roles in regulating hair growth in mice, with substance P promoting anagen progression and calcitonin-gene-related peptide inhibiting it.

This study found that platelet-rich plasma can transiently inhibit bacterial growth in vitro against multidrug-resistant strains from diabetic foot infections, although its efficacy diminished over time and did not affect biofilm formation.

This study observed significant variation in platelet concentrations across four different platelet-rich plasma (PRP) systems, suggesting that PRP system choice may affect treatment outcomes for hair growth.

This study indicates that individuals exposed to PPD mount varying immune responses, with either tolerance, subclinical inflammation, or allergy, suggesting no true non-responders to PPD.
