This symposium reported that DNA damage accumulation in aging stem cells affects genome integrity, highlighting novel mechanisms like Bmi1's role in DNA repair and the involvement of BATF in lymphoid differentiation.

This article discusses the characteristics of human hair, its damaging processes, and the potential repair effects of immuno-cosmeceuticals, but it reports no new clinical results.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

This study found that homocysteine-keratin accumulation in human hair increases towards the tips, linked to copper/iron-catalyzed demethylation of methionine, and may contribute to keratin damage.

The researchers reported that dsRNA from damaged skin activates TLR3, promoting hair follicle regeneration, while TLR3-deficient animals fail to initiate this process, suggesting potential therapeutic approaches for hair neogenesis.

Early stage bald spots are linked to skin inflammation and damage to the upper part of the hair follicle.

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 review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

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.

This study found that Origanum vulgare extract improved testicular structure and function in mice against finasteride-induced damage by enhancing antioxidant defense and modulating gene expression related to apoptosis.

This study found that ranitidine and finasteride may have cardiovascular and renal protective effects in mice by inhibiting TMAO synthesis and improving gut microbiota composition.

In this study, UCMSC exosomes showed protective effects against cisplatin-induced hearing loss in mice by improving hearing and promoting cochlear tissue repair.

Caffeine can damage hearing cells and affect hearing recovery after ear trauma.

Tanshinone IIA helps protect tissue from low oxygen damage by activating certain cell pathways.

Tanshinone IIA helps protect skin tissue from low oxygen damage by boosting certain cell markers.

This study developed a method to convert fibroblasts into sweat gland-like cells, suggesting potential for regenerating damaged skin and restoring sweat gland function.

In this study, researchers used a human skin organoid model to show that solar UV exposure damages hair follicles and skin, while exosomes from mesenchymal stem cells reduced inflammation and supported hair follicle regeneration.

This study found that an anti-atopic lotion containing fucoidan helped heal skin damage in hairless mice with atopic dermatitis by reducing skin thickness and modulating immune responses.

This study found that coconut oil use was associated with less hair damage than normal grooming practices, as indicated by hair breakage index and break stress measurements.

In this randomized controlled trial, oral intake of the probiotic Latilactobacillus curvatus LB-P9 significantly improved hair luster, elasticity, and participant satisfaction in individuals with mild to moderate hair damage compared to placebo, without significant adverse effects reported.

This review discusses recent advances in scarless wound healing, focusing on strategies to create pro-regenerative scaffolds for repairing damaged skin, and reports no new clinical results.

In this study, researchers found that hair follicle-derived mesenchymal stem cells, modified to overexpress extracellular matrix protein 1, significantly improved liver function and reduced liver damage in cirrhotic mice by inhibiting hepatic stellate cell activation and TGF-β/Smad signaling.

This study developed a zinc-infused egg white and GelMA hydrogel that enhanced cellular processes crucial for wound healing, including fibroblast proliferation and collagen expression, and demonstrated promising biocompatibility and bioactivity in vivo, suggesting potential effectiveness in repairing damaged tissues.

This study found that mercury chloride administration in rats led to decreased intraepidermal nerve fibers and increased Langerhans cells, suggesting small nerve fiber damage after mercury poisoning.

This study found that peach kernel oil extracted via supercritical fluid extraction had higher quality and antioxidant properties than oil obtained by other methods, effectively protecting human hair follicle keratinocytes from oxidative damage.

Riboflavin with blue light speeds up hair dyeing, making it faster, safer, and long-lasting with less hair damage.

This study on mice found that activating TRPML channels with MLSA1 promoted hair regeneration, accelerated hair cycle transition, and influenced human dermal papilla cells to secrete hair growth promoting factors while reducing hair growth inhibitors and oxidative damage.

This study found that modifying adipose-derived stem cells to overexpress the adhesion protein JAM-A increased the adhesion and resilience of dermal papilla cells in the context of androgenic alopecia, potentially facilitating hair regrowth despite challenges such as damage from dihydrotestosterone and macrophages.

This review suggests that the mTOR signaling pathway may play a significant role in hair follicle health by influencing the effects of Vitamin D receptor deficiency, potentially contributing to hair follicle damage and related hair loss conditions.

This study reported that urban pollution accelerates facial wrinkle development and increases pigmentation severity in Chinese women over 30, whereas UV exposure affects these signs from age 20. After 45, pollution becomes a key contributor to skin aging.
