This study developed a double-network hydrogel using polyacrylamide and catechol-chitosan to enhance mechanical properties and promote drug release, aiding in inflammation regulation and wound healing for chronic wounds with challenging microenvironments.

This review discusses recent molecular biology advances in the human phenol sulfotransferase gene family and reports no new results; the authors highlight its relevance for studies of endogenous and xenobiotic metabolism.

This study found that brindled mottled mice, a model of Kinky hair syndrome, exhibited abnormal development of catecholamine neurons, with increased TH-immunoreactive neurons and altered neurochemical profiles compared to controls.

This study developed an efficient method for converting polymeric procyanidins into high-purity oligomeric procyanidins using a semisynthetic approach combined with separation techniques.

This study reports that the metanephrine content was significantly higher in patients with alopecia areata compared to those without the condition.

In this study, researchers identified that keloid fibroblasts respond to neurotransmitters from catecholaminergic nerves by producing bone matrix proteins, mediated by β1-adrenergic receptor activation, leading to fibro-osseous reprogramming; blocking this signaling in a rodent model prevented the development of keloid-like pathology.

This study found that a catechins-rich Assam tea extract demonstrated antioxidant effects and hair growth promotion in mice, suggesting its potential as a natural alternative for treating hair loss.

In this study, partially purified apple polyphenols were found to inhibit preadipocyte differentiation in mouse cells by reducing GPDH activity and triglyceride accumulation.

In this study, the herbal hair colorant formulation HD-3, with a mix of specific herbs, was most effective at coloring hair and highly accepted by volunteers.

This review discusses the brain-skin connection, the skin's role in stress response, and highlights unmet challenges in understanding stress-induced skin inflammation but reports no new experimental findings.

This review explores the complex endocrine functions of human skin and its role as a peripheral endocrine organ, but reports no new clinical results.

This study suggests that melatonin plays a role in hair follicle function by modulating growth and pigmentation, and it may act as a protective agent in active hair growth phases.

This review examines the health benefits of green tea, focusing on catechins, but reports no new findings; the authors emphasize potential benefits for conditions like cancer, heart disease, and diabetes.

This review collected findings on the various cosmetic and therapeutic properties of tea extracts, highlighting their antioxidant, anti-inflammatory, and photoprotective effects among other benefits for skin and hair care.

This study found that children with alopecia areata experienced more stressful life events and excreted higher levels of catecholamines compared to healthy siblings.

This review highlights that children with adrenal disorders may experience neurological and psychiatric symptoms, with potential long-term cognitive and behavioral effects from excess glucocorticoids.

This study found that Camellia sinensis (tea) extracts may protect hair from UV-induced damage and color change, with efficacy linked to higher concentrations of key compounds like catechins.

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 suggests that guava leaf extract may inhibit hair loss by downregulating genes involved in androgen synthesis, potentially offering a natural alternative for treating androgenetic alopecia.

This study found that concentrated clusters of noradrenergic nerve fibers form a longitudinal linear system in rat skin, particularly innervating arrector pili muscles.

In this study, the pharmacological action of dobutamine on rabbit retinae was found to be distinct from that of other dopamine analogs like apomorphine and N-methyl-dopamine.

This study found that Pseudomonas DL7 completely degraded 600 mg/L of Sunset Yellow FCF in 48 hours at pH 9, indicating potential for biomineralization of this dye.

Coffee and tea might help hair growth in balding individuals, but side effects and alternative uses are being considered.

In this study, autopsies of children who suffered fatal abuse revealed stress-associated markers like telogen effluvium and thymus involution, which may help pathologists identify chronic abuse cases.

This study found a significant overlap between gene expression signatures of alopecia areata and certain chronic inflammatory skin disorders, suggesting shared biological processes may drive their co-occurrence and providing a foundation for future research into distinct comorbid subtypes.

This study found that Punica granatum ethanolic leaf extract may alleviate skin fibrosis in rats by modulating inflammation-related pathways and reducing dermal alterations.

This narrative review explores how psychological stress may contribute to premature skin aging by affecting dermal collagen and elastin remodeling through neuroendocrine, molecular, and cellular pathways, highlighting potential therapeutic targets to preserve skin structure and function.

This review discusses the potential of green tea, especially its catechin EGCG, in reducing PCOS symptoms like insulin resistance and androgen levels, but reports no new clinical results and emphasizes the need for further research.

This review highlights that disturbances in neuroimmune communication, particularly between sympathetic nerves and macrophages, may contribute to autoimmune diseases like rheumatoid arthritis and type 1 diabetes, and suggests potential therapeutic avenues by restoring this communication in preclinical and early clinical studies.

This study found that external application of DGD activates the Wnt/β-catenin signaling pathway, promoting hair follicle anagen phase entry, and is a more effective and safer treatment for androgenetic alopecia in mice compared to oral administration.
