This article reviews current understanding of dermal fibroblasts' structure and function, highlighting their crucial role in connective tissue formation and repair, which is important for selecting effective treatments for age-related skin changes.

In this laboratory study on mice, researchers found that both platelet-rich plasma and salmon DNA serum promoted wound healing, with platelet-rich plasma providing faster results due to its bioactive growth factors.

This study demonstrated that derivatives of dehydroepiandrosterone (2a-b, 3a-f, and 4a-f) significantly reduced viable LNCaP prostate cancer cells, suggesting potential therapeutic use for metastatic prostate cancer, while finasteride did not alter cell viability.

This special journal issue reviews various uses of injectables in aesthetic medicine, including treatment innovations with neuromodulators and dermal fillers, but reports no new empirical findings.

Micrografts are useful for healing wounds, regenerating bone and periodontal tissues, and improving hair transplantation outcomes.

Tailored nonsurgical cosmetic procedures are crucial for safely treating diverse skin types, especially skin of color.

Multi-pass laser skin treatments improved healing, reduced pain, and had no major complications.

The document summarizes recent dermatological treatments and advances in areas like pediatric care, wound healing, skin closure, light-based therapies, pigment disorders, hair loss, immunotherapy, infection management, melanoma, drug reactions, and facial rejuvenation.

This study found that modifying biphasic calcium phosphate/poly(methyl methacrylate) bone cement with human hair keratin improves its hydrophilicity, mechanical properties, and supports bone repair in rats, indicating potential for orthopedic applications.

This study found that a novel bioceramic/alginate hydrogel with photothermal properties and multiple ion release effectively reduces infection and inflammation, and enhances osseointegration in early-stage peri-implant lesions, potentially improving dental implant survival rates.

This study found that an injectable calcium alginate-amelogenin hydrogel is biocompatible, degradable, anti-inflammatory, and promotes osteogenesis, which may enhance the bone healing process in jaw and facial bone defect areas by mediating the bone immune microenvironment.

This review discusses the medical and dental applications of polyhydroxyalkanoates (PHAs), highlighting their potential for improving drug delivery and providing biocompatible solutions for medical devices, but reports no new clinical results.

Hair follicles in injured skin can quickly accumulate minerals, especially calcium and phosphorus.

This study identified two types of calcium in human scalp hair shafts: easily removable calcium, likely as calcium soaps, and more stably bound calcium, possibly related to Ca-binding proteins.

This study found that the diphosphonate ethan-1-hydroxy-1,1-diphosphonat was the most effective compound in preventing calcifications in rats induced by DHT, compared to other phosphatase inhibitors and polyphosphates tested.

In their commentary, the authors introduce additional cosmetic procedures—thread lifts, temporal lifting with dermal fillers, and facelifts—that may lead to type 2 pressure alopecia, expanding the understanding of this condition's potential causes beyond the original classification tied to cosmetic injections and sustained external pressure.

This study found that mild skin injuries in rats, especially those dosed with dihydrotachysterol, lead to mineral deposits in hair follicle tissue within 6-12 hours, as confirmed by chemical and X-ray diffraction analyses.

This study proposed a hypothesis for cutaneous calcinosis, suggesting that feeding DHT and subsequent epilation lead to ATP release and calcium orthophosphate formation, initiating calcification in rats.

In this study, keratin‐based hydrogels incorporating calcium ions were developed to effectively deliver atorvastatin, showing potential for localized anti‐fibrotic therapy through controlled drug release and maintaining drug bioactivity in vitro, supported by thorough physicochemical and mechanical characterization.

This study identified two types of calcium in human scalp hair, with one type highly variable between individuals, potentially impacting the analysis of environmental and medical factors related to hair calcium.

This study developed keratin-based hydrogels with improved water solubility and tunable properties, demonstrating excellent cytocompatibility, suggesting potential for biomedical applications.

In this study, researchers identified a novel biomarker of oxalate metabolism, which plays a crucial role in conditions like hyperoxaluria and kidney stones, marking the first time this detection has been reported.

This case report identified trichorrhexis nodosa in a patient, likely due to the topical use of an ayurvedic preparation containing calcium hydronide.

This study used theoretical calculations to show that phosphates strongly bind to cerium dioxide surfaces in various stable configurations, with spectral signatures identifiable in the infrared and Raman spectra, informing future experimental efforts in controlling the enzymatic activity of ceria nanoparticles.

This study found that human placenta extract may be a promising pulp-capping material, causing less intense chronic inflammation and thicker dentine bridge formation compared to mineral trioxide aggregate in dogs' teeth.

Human hair keratin can be used in many medical applications.

Keratin could help create enamel-regenerating toothpaste in a few years.

This study found that mesenchymal progenitor cells from human hair roots seeded onto polymer scaffolds stimulated the production of mineralized proteins, enhancing bone-like structures, with optimal results at a pore size of 35 µm.

This case report describes ALP elevation in a patient with severe OA that normalized after bilateral knee replacements, highlighting a potential link between OA and ALP levels.
