Pili annulati is caused by a protein metabolism disorder affecting hair structure.

This study observed that mercury-lamp irradiation may cause cleavage of disulfide bonds in keratins of white hair, leading to the formation of thiols in laboratory settings.

This study found that human hair shows progressive damage from UV and gamma radiation exposure, with fluorescence intensity serving as a sensitive measure of radiation-induced changes.

This study found that hair care products containing fermented papaya, fermented mangosteen, and caffeine significantly inhibited hair loss, increased hair density and thickness, and improved hair follicle structure in individuals with androgenic or diffuse alopecia over three months compared to placebo and caffeine controls.

In this study, topical administration of secretome hypoxia mesenchymal stem cells gel increased IL-10 and decreased TNF-α gene expression in a fluconazole-induced alopecia-like model in rats, with the 40 μL dose having the most significant effect.

In this study, secretomes from hypoxic mesenchymal stem cells were found to increase PDGF and reduce IL-1β gene expression in rats, potentially offering an effective topical treatment for alopecia caused by long-term fluconazole use.

This study suggests that administering SH-MSCs gel might decrease IL-6 expression and increase TGF-β expression in alopecia-like rats, indicating potential for alopecia therapy.

This review found that commercial influences may affect how male baldness is represented as a disease and how treatment options are presented, often omitting limitations.

This study found that using SH-SY5Y cell lysate in Western blot analysis may improve the diagnosis of Satoyoshi syndrome by providing more consistent and clear immunoreactive band patterns compared to brain homogenate, potentially leading to earlier diagnosis and treatment.

This study found that an aqueous extract of Bacopa procumbens improved motor function and preserved neuronal structure in a mouse model of Parkinson's disease, suggesting its neuroprotective potential.

This article discusses the effectiveness and indications of sex hormone therapy for various skin disorders and emphasizes the importance of avoiding androgen-effective contraceptives, but reports no new clinical results.

In this mouse study, researchers found that orally administered low-molecular-weight fish collagen peptides significantly improved hair regrowth by both enhancing growth-promoting pathways and reducing inhibitory mechanisms.

This study found that combined dietary supplementation of sodium hyaluronate and eggshell membrane was associated with various improvements in skin and coat health markers in healthy Ragdoll cats.

In this study, researchers developed a new sodium alginate/chitosan/Zn2+ hydrogel that showed improved physical properties, antibacterial activity, and biocompatibility, and demonstrated enhanced wound healing and skin regeneration in an in vitro model.

In this study, oral supplementation of Microcore’s TrichovitalsTM significantly improved the appearance of facial skin, hair, and nails over 12 weeks in healthy middle-aged adults compared to a control group.

This study established an animal model using UV-irradiated C57BL/6 mice to assess hair luster, reporting that UV exposure alters keratin-associated protein gene expression, and suggested potential for developing effective hair care products by evaluating treatments like oral minoxidil.

This study found that applying Hypericum perforatum methanol extract-containing gel to experimental burns in rats reduced collagen discoloration and vascular damage while preserving hair follicles and epidermal thickness compared to treatment with silver sulfadiazine cream.

This study found that for men with moderate-to-severe LUTS/BPH, 6 months of treatment with tamsulosin plus the hexanic extract of S. repens was as effective as tamsulosin plus a 5-alpha-reductase inhibitor but had better tolerability.

This study found that hypoxic preconditioning of nanofat from donor mice reduced its vascularization capacity in vivo, suggesting that this approach cannot currently enhance nanofat's regenerative potential.

This study found that neonatal administration of finasteride reduced sensitivity to alcohol's motor-stimulating effects and increased preference for novelty and initial alcohol consumption in rats, suggesting a role in alcohol vulnerability.

This study found that ancient and modern Chinese goats share close genetic ties, originating from the Fertile Crescent, with genetic divergence influenced by China's climatic divisions.

This study examined gene expression in cashmere goats and identified key pathways and molecular regulators that influence hair follicle growth stages and melatonin's role in promoting cashmere growth.

This study found that Czech women with polycystic ovary syndrome in their thirties had a significantly worse cardiovascular risk profile compared to a control group, independent of obesity.

In this study, gene expression changes in rat whisker follicles after methamphetamine administration may serve as indicators of the drug's rewarding effects and potential addiction pathways.

This study found no significant difference in psychological stress between males with and without androgenetic alopecia. Social and cultural factors might influence perceptions of alopecia's impact.

This study examined genetic risk factors for alopecia areata in the Jordanian population but found no significant association between the 21 targeted risk loci and the condition, emphasizing variability in genetic predisposition across ethnic groups and potential non-genetic triggers.

This study found that gene expression patterns can effectively distinguish the cashmere growth cycle stages and highlight molecular pathways, suggesting melatonin's role in regulating cashmere growth in Inner Mongolian goats.

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 study explored the wound healing potential of a natural marine soft coral-derived nanoparticle-based gel in a diabetic excision wound model, finding it effectively regulates proinflammatory cytokines and inhibits enzymes related to wound healing.

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.
