This study found that exogenous glutamic acid can promote hair growth and keratinocyte proliferation, suggesting a novel signalling pathway in the skin.

In this case series study, two Peruvian women with virilizing ovarian tumors called Sertoli-Leydig cell tumors showed clinical improvement and normalization of androgens after surgical treatment, highlighting the diagnostic challenge of these rare presentations at different ages.

This article reviews the mechanisms by which minoxidil stimulates hair growth and reports no new clinical findings.

This study found that linseed oil, rich in flavonoids and terpenoids, significantly improved burn wound healing in terms of faster contraction, reduced inflammation, and enhanced tissue regeneration compared to other treatments, without adverse effects.

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 PRP combined with dalteparin and protamine microparticles may enhance hair growth by increasing hair thickness compared to PRP alone.

This study reports that plasma rich in growth factors appeared to improve hair follicle regeneration and patient satisfaction in individuals with androgenetic alopecia, though further trials are needed.

This review highlights that microneedling shows some promise for improving hair growth in alopecia, particularly when used with other treatments, though more research is needed to establish its efficacy and protocols.

This review found significant progress in 3D bioprinting for surgery, noting advances in creating complex tissue constructs, while highlighting ongoing challenges like vascularization and integration with host tissue, emphasizing the need for further research and regulatory development.

This article discusses the importance of individualized treatment plans based on the morphological characteristics of the aging face in surgical rejuvenation, but it provides no new findings.

This review summarizes the effects and complications of bariatric surgery on skin, noting it can alter existing skin conditions like psoriasis and trigger new dermatoses, but provides no new clinical results.

This study found that crosslinking buffalo gelatin with different methods can modify its properties and potential as a skin substitute, though double-crosslinking may increase immunogenicity slightly.

This review discusses the impact of COVID-19 on the endocrine system and reports no clinical results; the authors emphasize the need to investigate endocrine damage during and after COVID-19 infection.

This study found that millimolar concentrations of minoxidil in the skin induced VEGF production through HIF-1 stabilization by inhibiting PHD-2, implying a molecular mechanism for hair growth promotion.

In this randomized study, ViviScal® significantly outperformed a fish extract in increasing non-vellus hair count and achieving clinical and histological improvement in young males with hereditary androgenic alopecia.

This study observed that aging leads to significant structural and biological changes in the scalp's hair follicle environment in women, which may affect hair growth.

In this study, CD34-positive progenitor cells in irradiated salivary glands were observed to potentially aid in blood vessel formation and remodeling, suggesting their role in tissue healing after radiotherapy.

This review highlights new treatment options for hair restoration, including platelet-rich plasma and stem cell therapy, which have shown efficacy in increasing hair count and density for androgenetic alopecia and alopecia areata, but presents no original clinical data.

This study investigated nanocomposite scaffolds made from alginate, chitosan, and graphene oxide to promote the proliferation of spermatogonial stem cells, finding the ALGCS/GO30 scaffold to be particularly effective due to increased proliferation markers and PLZF protein expression compared to controls.

This laboratory study found that nonanal, a plant scent compound, may stimulate growth factors and cell proliferation in human hair follicle dermal papilla cells, suggesting a cAMP-mediated mechanism.

Among in vitro and in vivo models, this study found that Miscanthus sinensis var. purpurascens flower extract may promote hair growth, potentially by modulating growth factor expressions and facilitating earlier hair follicle transitions in treated mice.

This study demonstrated that water-soluble peptides from egg yolk, termed "hair growth peptide," stimulated human hair follicle cell growth and improved hair growth in female pattern hair loss.

In this study, a novel portable LED device significantly accelerated wound healing in rats, with faster wound closure, increased collagen deposition, and more microvessels at a higher radiation intensity, suggesting its potential for innovative wound management.

This study explored peripheral blood immune dysregulation in alopecia areata through single-cell analyses, identifying systemic changes linked to disease severity and key signaling roles for monocytes, NK cells, and memory T cells, suggesting potential therapeutic targets.
