This study reports that melanocytes form a defined photoresponsive network in the skin that reads environmental light cycles and may influence the sleep-waking cycle similar to the pineal gland.

This study found that resveratrol significantly alleviated testicular damage in male rats caused by finasteride, which otherwise led to decreased testosterone levels and various histopathological alterations in the testes.

This study found that finasteride treatment in male rats altered steroid hormone homeostasis and caused kidney damage, suggesting potential risks for patients with renal dysfunction on androgen or antiandrogen therapy.

In this study, researchers suggest that strategic early intervention during fetal wound healing could lead to significantly improved long-term skin regeneration outcomes.

This study suggests that TGF-alpha may function in an autocrine or juxtacrine manner rather than promoting cell proliferation during hair growth cycles in ferrets and sheep.

This paper highlights the growing scientific interest in plant extracts for cosmetics due to their potential benefits, including antioxidant, antimicrobial, and protective properties, while emphasizing the need for quality and safety assessment to mitigate possible adverse reactions.

This study demonstrated that both classical and atypical BSE strains from cattle can be transmitted to goats, highlighting the importance of surveillance in protecting public health.

This review reported that tripeptides, such as GHK and KdPT, show promise in enhancing wound healing through multiple mechanisms, including promoting cell migration, collagen deposition, and angiogenesis, while offering antimicrobial and anti-inflammatory benefits for both acute and chronic wounds.

This review explores nano-quercetin formulations to enhance the solubility, stability, and targeted delivery of quercetin, highlighting its potential efficacy in treating cancer, inflammation, metabolic diseases, and tissue regeneration, though challenges in biocompatibility, toxicity, and production remain, per this source.

This study reports that a novel gain-of-function mutation in TMEM173, combined with polymorphisms in TMEM173 and IFIH1, results in a distinct clinical phenotype with features of SAVI, including alopecia and photosensitivity.

This review discusses various treatments for noncicatricial alopecias, such as androgenetic alopecia and alopecia areata, including mesotherapy, microneedling, and platelet-rich plasma therapy, noting that outcomes vary across these procedures.

This study found that dietary supplementation with collagen, chondroitin sulfate, low-molecular weight hyaluronic acid, Pycnogenol®, and coenzyme Q10 significantly improved skin hydration, elasticity, nail hardness, and hair condition in patients with age-related dermatological changes after 12 weeks.

Hair follicles could be used for targeted drug delivery, with liposomal systems showing promise for this method.

This review discusses the roles of hair follicles and sebaceous glands in percutaneous transport and reports no new results, noting a lack of adequate models and methodologies.

This review discusses current treatment strategies for alopecia and highlights the potential of lipid-based nanoparticles to improve drug delivery to the scalp and hair follicles, noting their ability to enhance skin penetration and drug stability while outlining associated challenges and the need for further research.

This review suggests that although hydrolyzed collagen peptides with certain supplements may improve skin elasticity and joint function, evidence for collagen's anti-aging and regenerative benefits remains inconsistent.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.

This research presents a comprehensive workflow for producing EMA-compliant autologous keratinocyte-based therapies for wound healing and explores miRNA-mediated regulations in human keratinocytes and adipose-derived mesenchymal stem cells.

In preclinical studies, topical CUR61414 reduced Hh signaling and shrank BCCs in mice, but this study found no clinical efficacy in human superficial or nodular BCCs.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

This study observed that unpigmented keratinocytes saturate quickly with foreign substance uptake compared to pigmented melanocytes, where melanin significantly enhances binding.

This study found a statistically significant increase in glycosylated hemoglobins among patients with adult-acquired panhypopituitarism undergoing long-term GH replacement therapy, with two developing diabetes requiring treatment.

This review discusses the developments over the past five years in nanozyme-based theranostics for tumor therapy, including their classification, design, and synergistic strategies. It also outlines the challenges and prospects of using nanozymes to enhance selectivity, biosafety, repeatability, and stability in therapeutic applications.

This study found that overexpression of miR-214 in keratinocytes inhibits hair follicle development and cycling by targeting β-catenin in the Wnt signaling pathway.

This review suggests that skin may largely protect itself from CYP-generated reactive metabolites due to higher conjugating enzyme activities, while highlighting limitations in modeling human skin metabolism experimentally.

This review discusses the pharmacological properties and physiological regulation of neuroactive steroids, focusing on their varied responses to stress and ethanol in rats, mice, and humans, but it reports no new findings.

This review classifies engineered nanomaterials by composition and application in biomedicine, highlighting diverse uses like regenerative medicine and potential occupational side effects, but reports no new clinical results.

This review summarizes that polyesters hold promise for vascular tissue engineering due to their mechanical properties and biodegradability, but optimizing their use in repairing damaged blood vessels remains challenging due to the complexity of vascular tissues.

This study reports that the tetrapeptide AcSDKP significantly promotes skin and hair health in vitro and ex vivo, suggesting it could be used cosmetically to counteract skin aging and hair loss.
