This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.

This study found that external light can rapidly activate hair follicle stem cells in animals via a retinal light-sensing pathway linked to the central and autonomic nervous systems.

This study examines the effects of excessive or prolonged exposure to blue light on retinal function and highlights its potential health implications, noting that both photoreceptor and intrinsically photosensitive retinal ganglion cells (ipRGCs) are particularly sensitive to blue wavelengths.

This study found that keratin filament networks in SG1 cells of mice undergo dynamic changes during cornification, impacting the barrier function of the stratum corneum.

This study demonstrated that in genetic mouse models, the calcium sensor Stim1, not Stim2, is essential for sweat secretion in sweat glands.

This study found that a water-soluble peptide from chicken egg yolk, named Hair Growth Peptide, improved hair growth in mice and female pattern hair loss through increased IGF-1 and VEGF production.

This study found that plasma cardiac troponin I levels were highest in subjects with alopecia areata, potentially indicating increased heart remodeling and a need for close cardiovascular monitoring in these individuals.

This study found that sensitive scalp is characterized by increased pH levels, redness, altered sebum composition, and a disrupted microbiome, suggesting these features could inform treatment approaches.

This study explored the complex roles of niche cells in regulating hair follicle stem cells, identifying specific cell functions such as signaling, sensing, and relaying messages, which could provide insights into treating hair loss conditions like androgenetic alopecia and alopecia areata.

This review discusses the effects of photobiomodulation, particularly its potential to reduce inflammation in various conditions, but it does not report new clinical findings.

In this study, using light masks to extend photoperiod was effective for maintaining the summer coat in horses and accelerating shedding in outdoor horses, but timing was crucial for success.

This study aims to assess how daily life factors affect sleep patterns and describe individual sleep changes across the year, with results to be published in future research.

This review highlights the role of the skin's photosensory system in mediating responses to UVA radiation, contributing both to immediate protective effects and to broader circadian and seasonal adaptations, but reports no new experimental results.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

This study found that male and female chicken feather morphology and color patterns can be extrinsically modified through molting and resetting the stem cell niche during regeneration.

This study introduced a simple and reliable in vitro assay capable of large-scale simultaneous screening of hair growth-promoting compounds using a 3D co-culture system of human dermal papilla and outer root sheath cells.

This review discusses the potential of hair follicle stem cells in hair regeneration therapies but reports no new clinical results, highlighting the need for further research to address existing challenges in their application.

This review explores the complex interactions of intrinsic and extrinsic mechanisms that regulate hair follicle stem cells and their role in skin homeostasis, aiming to advance understanding that could support future research on skin disorders.

This study reports two cases of severe alopecia areata showing seemingly permanent hair regrowth with a modified triamcinolone acetonide regimen involving epinephrine, and suggests a potential role for epinephrine in enhancing treatment efficacy.

This study identified a mutant in Arabidopsis with shorter root hairs due to early growth cessation, implicating the IRE gene in regulating root hair growth duration.

This study demonstrates that a new Adaptive Modulation and Coding method can improve control performance in Communication-Based Train Control systems using WLAN by reducing average delay through effective transmission mode selection.

This study found that PRX102, a peroxidase with a unique polar localization pattern, plays a role in root hair growth by aiding the transport of materials to the tips of growing root hairs.

In this study, the KPAI and KP-IGA scoring systems for assessing keratosis pilaris showed excellent interrater and intrarater reliability, offering standardized measures for clinical and research use.

This study found that colorectal cancer patients could be categorized into two groups based on mitochondrial-related gene features, with distinct survival outcomes and tumor microenvironment characteristics, suggesting these features could inform individualized treatment plans.

In a real-world registry study, ripretinib showed effectiveness with a median progression-free survival of 7.70 months and a tolerable safety profile in Chinese patients using it as a fourth-line treatment for advanced GIST, particularly benefiting those with non-gastric tumors.

This study found that calcitonin‐gene‐related peptide immunoreactive sensory axons in rats are predominantly involved in tissue maintenance rather than nociceptive functions.

This study describes GPRC5D's unique expression pattern in tissues that produce hard keratin, with retinoic acid inducing its expression in hair bulb cells and affecting keratin gene regulation.

This study found that the peach gene CTG134 mediates auxin-ethylene crosstalk, affecting root hair growth and hormone-regulated processes in plants.

This study used infrared spectral imaging to show for the first time the distribution of glypican-4 and glypican-6 in hair follicles across different growth phases, highlighting the potential of this technique for studying alopecia.

This study presents the G4 transgenic mouse model, which suggests a direct link between polycystic ovary syndrome and the Gm10800 gene, offering a valuable tool for understanding the disease and testing treatments.
