This study reviews the use of nanofat in facial rejuvenation and cosmetic surgery, highlighting its potential for improving skin appearance and treating conditions like wrinkles and acne scars, yet emphasizes the need for further research into its long-term efficacy and safety.

This review discusses the causes and preventive measures of limb amputations, emphasizing the importance of specialized surgical teams to improve function and aesthetics, but provides no new clinical findings.

This study found significant structural and compositional differences in hair affected by alopecia areata compared to healthy hair, using a range of physico-chemical investigation methods.

This study reviewed the use of 3D printing and bioprinting for tympanic membrane repair, comparing them with traditional materials and noting their clinical significance, while highlighting the need for further analysis of bio-ink selection strategies involving biopolymers, cells, and drugs.

This study found that intradermal injections of platelet-rich plasma were equally safe and effective for treating androgenetic alopecia, with higher platelet numbers possibly enhancing hair density and follicle diameter.

In this study, procerus and corrugator myectomy techniques during browlifts significantly improved dynamic glabellar wrinkles compared to browlifts without muscle resection over 12 months.

This study found that the guided SEFFI technique for facial volume restoration and anti-aging is minimally invasive with a low complication rate, suggesting it as a promising treatment option.

This review elaborates on follicular unit extraction as a hair restoration procedure and provides a detailed step-by-step guide but does not present new clinical results.

This discussion examines the aesthetic symptoms of perimenopause, such as hot flashes and skin changes, and reviews management options like hormone replacement therapy and topical cosmetics, emphasizing the importance of consistency in treatment to maintain results.

This review highlights that injectable biostimulatory agents like poly-L-lactic acid, polycaprolactone, and calcium hydroxyapatite are effective in regenerative aesthetics by enhancing collagen production, stimulating adipogenesis, and improving dermal quality, although further research is needed to standardize protocols and confirm long-term safety and efficacy.

In this study, maternal melatonin implantation in pregnant rabbits reduced hair follicle cell apoptosis and increased hair follicle density in their neonatal offspring, suggesting a beneficial impact on hair follicle development mediated through specific molecular pathways.

In this narrative review, researchers examined common misconceptions and questions about creatine monohydrate, addressing issues such as its potential effects on muscle benefits without exercise, interactions with caffeine, inflammatory properties, safety during pregnancy, and effects on adolescents, among others.

This study found that while most women reported aesthetic improvement after PRP facial injections, objective skin analyzer data showed no significant changes, but midface volume improvement was more likely in those with lower platelet counts and higher estradiol levels.

This article describes the significance of the Italian Association of Plastic Aesthetic Surgery's annual congress in European aesthetic plastic surgery, but reports no new research findings.

This study reviewed cases of filler-induced alopecia and found that hyaluronic acid injections were most commonly associated with this condition, highlighting that hyaluronidase treatments can rapidly restore hair density, while alternative interventions need further exploration.

This review discusses various extra facial esthetic indications of botulinum toxin, like neck rejuvenation and calf slimming, and reports no clinical results; essential tips for each indication are included.

This study assessed outcomes and complications of upper-face feminization surgery among 20 transgender patients, highlighting that insufficient browbone reduction was a common issue in prior surgeries, and emphasizing meticulous planning to prevent revisions and dissatisfaction.

This study found that electronically-operated pneumatic injections for administering a peptide-hyaluronic acid combination were well tolerated and led to significant improvement in hair density and thickness for men with androgenic alopecia over six months, though the exact mechanism remains uncertain.

This review discusses the role of dermal cells in hair follicle regeneration and morphogenesis and highlights their potential therapeutic implications, but it reports no new empirical findings.

This research found that Dlx3 plays a central role in hair formation and regeneration, with its absence leading to alopecia through disrupted differentiation and signaling pathways.

This study demonstrated that anagen can be induced in Stat3-disrupted mice, suggesting that both Stat3-dependent and independent pathways, possibly involving PKC, mediate hair cycle progression with required PI3K activation.

This review discusses the role of Hedgehog signaling in epidermal and hair follicle development and its involvement in basal cell carcinoma, without reporting new empirical findings.

This review concluded that botulinum toxins have various potential off-label uses for dermatological conditions, but further research is needed to fully establish their efficacy and safety in these applications.

This study in mice found that overexpressing Sonic Hedgehog in basal cells caused skin anomalies and a lack of certain hair fibers, underscoring its key role in hair follicle development.

Effective vaccines and treatments are crucial for long-term COVID-19 control.

Understanding tissue self-organization can improve treatments for diseases and advance regenerative medicine.

This study reviews the complex pathophysiological mechanisms of long COVID and suggests a "treatable trait" approach for targeted interventions based on these mechanisms.

In this study, transiently activating the sonic hedgehog signaling pathway in chickens transformed reticulate scales on the feet into feathers comparable to body feathers, without ongoing treatment, suggesting this pathway affects the diversity of bird skin appendages.

This narrative review explores how exosomes and cell culture-conditioned media are becoming key players in the cosmetic industry for skin rejuvenation and prejuvenation, emphasizing their multifunctional topical benefits and potential future applications.

This study suggests that distinct chromatin topologies allow different lineage-specific enhancers to regulate Hoxd genes in mouse vibrissae and chicken feather primordia, while conserved regulatory elements maintain transcriptional robustness in the embryonic trunk across species.
