In this study, researchers developed a biodegradable microneedle made of hyaluronic acid, intended to enhance drug delivery through the skin's stratum corneum and potentially promote hair growth by overcoming the skin's barrier function in alopecia treatment.

This study describes the use of a genetically engineered mouse model, mTurquoise2-Col4a1, to fluorescently label collagen IV and observe basement membrane dynamics during skin development, revealing its stability and pliability during rapid growth phases.

This study found that alopecia areata patients with a CCHCR1 gene variant had higher recurrence rates and structural abnormalities in hair compared to those without the variant.

This study demonstrated that cryogelation of human hair keratin allows the development of 3D scaffolds with tunable properties, supporting cell adhesion and proliferation for potential biomedical applications.

In this study, researchers developed isotretinoin-loaded Delonix polymeric nanoparticles that target hair follicles and found they effectively sustained drug release, reduced IL-6 production in vitro without inhibiting P. acnes, and may prevent isotretinoin-related skin irritation in vivo in Wistar rats.

This study found that keratin-75, discovered in enamel tissue, is secreted by ameloblasts using an unconventional pathway involving the ER-Golgi-Intermediate-Compartment and Golgi, differing from typical cytokeratin localization.

This review discusses the potential of exosomes and the secretome in stem cell-based regenerative therapies but reports no new experimental findings.

This study found that adding hair fibers to friction materials increased their friction coefficient stability and impact strength while decreasing wear rates, with 1% hair fiber content notably improving performance.

This study found that Mf-rich-fiber in human hair underwent significantly greater degradation by proteases than Ma-rich-fiber, especially when treated with Proteinase K.

This study demonstrated that human hair shafts can be anatomically separated to obtain intact micron and nano keratin filaments using solvents like performic acid and urea.

This review discusses various forensic applications of hair analysis, such as species identification and drug addiction testing, and reports no new study results.

This study reported a green synthesis method for copper oxide nanoparticles using pumpkin seed extract, achieving significant antibacterial activity against Bacillus subtilis and moderate cytotoxic effects against certain cancer cell lines, indicating potential biomedical applications for these eco-friendly nanomaterials.

This study highlights that current research efforts to deliver anti-acne drugs to hair follicles have primarily targeted healthy follicles, overlooking the distinct characteristics of pathologically clogged follicles in acne vulgaris.

This study employed a laser-based method to analyze how light reflection patterns vary on human hair fibers, revealing changes related to hair color and the tilt of the cuticle cells.

This study found that ovine dermal papilla cells exhibit robust aggregation in culture, offering a model to investigate the regulation of hair follicle dermal papilla size.

This study found that chitosan nanofibrillar scaffolds accelerated skin wound healing in mice by enhancing cell adhesion, proliferation, and regeneration of epidermis and dermis compared to other forms.

This study found that a genetic variant in the EDAR gene leads to typical East Asian hair characteristics by increasing signaling output, as shown in transgenic mice experiments.

This review highlights the increasing clinical applications of high-frequency ultrasonography in dermatology, particularly for assessing the depth of skin tumors and monitoring inflammatory skin diseases, but reports no new clinical results.

This protocol describes using two-photon laser-scanning microscopy to study hair regeneration in live mice, offering detailed imaging capabilities for observing hair follicle stem cell behavior and manipulating cellular populations.

This study found that nanostructured lipid carriers with clobetasol propionate significantly enhance follicular drug delivery compared to commercial cream, and manual massage further doubles follicular retention.

This study found that combining platelet-rich plasma with adipose-derived mesenchymal stem cells significantly improved diabetic wound healing in rats by enhancing angiogenesis and modulating the Notch signaling pathway.

This study found that a ceria nanozyme-integrated microneedles patch accelerated hair regeneration in an androgenetic alopecia mouse model more effectively than minoxidil, with reduced application frequency and minimal skin damage.

This study found that dual 5α-reductase inhibition in rats led to decreased sperm motility and altered morphology, resulting in subfertility.

Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.

This study found that artocarpin delivered via alginate/chitosan microparticles effectively suppressed the growth of hamster flank organs compared to artocarpin in solution form, without significant systemic effects.

This study investigated a new formula called SV-loaded nanospanlastics for topical application to treat androgenic alopecia. It showed similar effectiveness to minoxidil lotion but with fewer adverse effects when used to enhance dermal delivery and efficacy of sodium valproate.

This study found that phyto-vesicles of ß-sitosterol showed better absorption and improved activity for treating androgenetic alopecia in rats compared to the compound and its complex.

In this study, researchers developed and tested a gel containing apocynin-loaded nanoparticles that showed promising results in treating rheumatoid arthritis in rats, suggesting potential for novel topical treatments in inflammatory conditions.
