This review highlights the potential of valorizing citrus by-products, particularly hesperidin from orange peels, as sustainable ingredients in skincare for antiaging, pigmentation, wound healing, and UV damage protection, emphasizing hesperidin's role in a circular economy approach.

This study reports a unique case of common variable immunodeficiency with autoimmunity linked to a heterozygous S250C variant in the autoimmune regulator gene, suggesting a potential molecular basis for this combination.

This study found that monounsaturated oils like olive oil penetrate hair fibers effectively, whereas polyunsaturated oils typically do not penetrate beyond the cuticle.

This study concluded that Polyquaternium-10 conditioner softens the surface of the scale face on hair fibers.

This review reports that Janus kinase inhibitors and regenerative therapies, such as exosomes and platelet-rich plasma, significantly improve scalp hair regrowth in moderate-to-severe alopecia areata, though challenges like high relapse rates and socioeconomic barriers remain, underscoring the need for personalized treatment protocols.

This study suggests that black ginseng concentrate protects human follicle dermal papilla cells against oxidative stress, potentially offering a natural approach to prevent cellular dysfunction linked to hair loss.

This study suggests that Staphylococcus capitis ferment filtrate (SCFF) may promote hair growth and scalp health by modulating pathways related to hair loss, aging, and oxidative stress in vitro.

This article discusses the structure and function of sebaceous glands and their role in skin moisture but reports no new research findings.

This study found that the Dun camouflage color in horses is due to TBX3 expression, which causes uneven pigment deposition, whereas non-dun coat colors result from regulatory mutations affecting TBX3 expression.

This study found that chemical and photochemical oxidative processes modify the main classes of proteins in hair, confirmed through microspectrophotometric, fluorescence microscopy, and electrophoretic methods.

This review discusses the discovery and potential therapeutic uses of proteasome inhibitors across various diseases, including cancer and autoimmune conditions, but does not present new clinical data.

This paper reviews the diagnostic criteria, etiological factors, and treatment approaches for PCOS, highlighting the importance of considering metabolic issues such as insulin resistance and obesity, but reports no new findings.

This study found that mouse skin CD4(+) memory T cells are in equilibrium with the circulation under steady state but increase in specific clusters in response to infection or inflammation.

This study found that PDGFA is critical for the proliferation and maintenance of adipocyte stem cells in skin but not other white adipose tissues, highlighting unique regulatory mechanisms in different tissue depots.

This review discusses managing common and notable adverse events associated with the antibody-drug conjugate trastuzumab deruxtecan in patients with HER2-positive unresectable/metastatic breast cancer and reports no new clinical results.

This study found that skin microbiota, particularly in wild-type mice, promotes wound-induced hair follicle neogenesis and wound healing, highlighting the potential downsides of routine antibiotic use on skin regeneration.

This study found that betasitosterol-loaded nanostructured lipid carriers, when added to butter, improved its nutritional profile and antioxidant properties, maintaining stability over a three-month storage period.

In this study, a transgenic mouse model was used to demonstrate that targeted cell loss in different tissues led to varying degrees of regenerative outcomes, including reversible impaired glucose tolerance, irreversible hair loss, and permanent moderate deafness.

This study observed that direct exposure to androgens in Western clawed frogs differentially affects thyroid receptor and deiodinase gene expression in male and female tissues, offering insight into sex-specific metabolic pathway activation.

In this study, researchers identified the PLD-mGluR protein in primary mechanosensory terminals as the homomeric GluK2 kainate receptor, functioning purely metabotropically, which is suggested to be common to various sensory endings.

In this study, researchers found that disrupting desmoglein 3 signaling in a mouse model of pemphigus vulgaris activates normally quiescent hair follicle stem cells, compromising their multipotency but prompting a regenerative response that restores stem cell function and structures.

This chapter provides an overview of the complex chemical and physical structure of the hair surface, detailing how factors like ethnicity, environmental stress, and cosmetic treatments can alter its properties and influence the adhesion of hair care products.

In this narrative review, researchers found preliminary evidence suggesting that minoxidil, both topical and oral, may enhance nail growth and improve nail strength and appearance, though more extensive studies are needed to confirm its efficacy and safety for this off-label use.

This study found that platelet-rich plasma therapy significantly improved hair density, diameter, and reduced inflammation in androgenetic alopecia patients compared to placebo, though individual responses varied.

This source concludes that repurposing existing drugs, such as using metformin with other treatments in advanced non-small cell lung cancer, may enhance cancer patient outcomes, although various technical and legal challenges need addressing.

This review explores the effects of caffeine on cancer, cardiovascular, immunological, inflammatory, and neurological diseases, including its use in sports, and discusses advancements in caffeine delivery through novel nanocarrier-based formulations.

This study found that mutations in the TULP3 gene are associated with progressive degeneration of the liver, kidney, and heart in adults, highlighting the importance of early detection and management.

This article reviews applications of optical coherence tomography techniques in medicine, including for diagnosing androgenic alopecia and monitoring blood coagulation, but provides no new clinical results.

This review summarizes current knowledge on tight junctions in mammalian skin and their role in drug delivery and interaction with other barrier components, but reports no new experimental results.

This review discusses the emerging "endocrine phenotype" of COVID-19, highlighting the implications for managing diabetes, obesity, vitamin D deficiency, and other endocrine conditions in affected patients.
