In this study, researchers developed a dissolvable microneedle patch combining HA-TEMPO and Portulaca oleracea L.-derived nanoparticles, which effectively reduced oxidative stress and inflammation in an atopic dermatitis model while restoring immune balance, suggesting a promising treatment strategy.

This study demonstrated that intraoperative bioprinting using a bioink with human adipose-derived extracellular matrix and stem cells achieved successful reconstruction of full-thickness craniomaxillofacial skin defects in rats, promoting wound closure, adipogenesis, and hair follicle-like structure formation within two weeks.

The hydrogel helps heal wounds without scars by releasing two drugs gradually.

This study observed distinct variations in hair medulla patterns among people with different Ayurvedic Prakruti types, linking stronger hair integrity to Kapha-dominant types and weaker, fragmented medullae to Vata and Pitta-dominant types, potentially aiding in Dosha-specific hair care and assessment.

This study concluded that sodium lauryl sulfate is very toxic to hair, damaging its structure, while natural conditioners help protect hair integrity and improve consistency and shine.

This study found that consuming raw cheonggukjang improved various measures of scalp hair condition in middle-aged women over a 12-week period.

This study identified a specific genetic variant in the CCHCR1 gene that may contribute to alopecia areata through impaired keratinization, suggesting an alternative mechanism beyond autoimmune causes.

This study found that adipose-derived mesenchymal stem cells produced more anti-inflammatory and pro-angiogenic cytokines on electrospun scaffolds, which enhanced wound healing and macrophage activity in a rat model.

This study found that PCL-based nanofiber scaffolds enhanced cell proliferation and extracellular matrix deposition, suggesting they show promise as a cell delivery system for improving skin wound healing.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

This publication reviews the World Professional Association for Transgender Health's Standards of Care for supporting transgender and gender nonconforming people, with adjustments needed for diverse global contexts and no new clinical results.

This study found that intradermal adipocyte lineage cells in mice are necessary and sufficient to activate follicular stem cells, highlighting their role in regulating skin stem cell activity.

This review discusses the preclinical and clinical data on teriflunomide for multiple sclerosis, highlighting its selective action on immune cells without causing clinical immune suppression, and provides no new clinical results.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This review discusses five potential mechanisms for kidney stone formation, including urinary supersaturation, Randall's plaques, sex hormones, the microbiome, and immune responses, and reports no new results.

This study found that removing PPARγ specifically from mouse adipose tissue led to severe fat loss, insulin resistance, diabetes, and associated metabolic abnormalities.

This study identified a set of wound-induced genes in planarians that play a role in regeneration initiation, with some genes specifically activating within regenerative cells called neoblasts.

This review discusses recent advances in skin penetration mechanisms, specifically focusing on the enhanced understanding of the follicular pathway and its implications for transdermal therapies, immune system targeting, and nanoparticle safety.

This study found that using a Picosecond IR Laser (PIRL) on mouse skin led to less tissue damage and scarring compared to conventional surgical lasers and tools.

This study found that glycolytic metabolism and lactate production are crucial for hair follicle stem cell activation, and manipulating these processes can stimulate the hair cycle.

In a mouse model, this study demonstrated that a microneedle patch system using keratin and integrated with MSC-derived exosomes and UK5099 promoted hair regrowth more efficiently than traditional delivery methods.

This study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.

This study demonstrates the potential of using bioengineered follicles from adult tissue-derived stem cells for fully functional hair regeneration, illustrating possible applications in organ replacement therapy.

This study found that macrophages near hair follicles contribute to the activation of skin epithelial stem cells in mice, suggesting a novel role for macrophages in regulating hair growth.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

This review discusses the development of an interdisciplinary guideline on Post-COVID/Long-COVID symptoms, diagnostics, and therapies by the Deutsche Gesellschaft für Pneumologie, reporting no new results but highlighting ongoing updates based on emerging knowledge.

This study observed that keratose, derived from human hair, integrated well in mouse tissue and remodeled with collagen, suggesting potential as a non-toxic biomaterial for regenerative applications.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

This study found that macrophages play a crucial role in nerve regeneration by regulating Schwann cell dynamics and remyelination, with Gas6 identified as a key factor in this process.
