This case report suggests that methylphenidate may lead to hair loss in some patients, observable when stopping and starting the medication.

This study found that TSC2-null fibroblast cells from TSC skin hamartomas can induce hair follicle formation and hamartomatous changes in keratinocytes, with active mTOR signaling observable in a mouse xenograft model.

This study reported that a new laser scanner using 655 nm red and 808 nm infrared lasers significantly improved hair density in patients with androgenic alopecia compared to both a laser hat and no treatment, without observable adverse effects.

This study found that using a combination of Alginate-TEMPO-oxidized cellulose nanofiber-α-tocopherol membranes and Pluronic-α-tocopherol hydrogels facilitated better wound healing in diabetic rats through enhanced angiogenesis and no observable toxicity compared to using each treatment individually.

This study found that applying 5% topical minoxidil twice daily significantly increased nail growth rate in healthy participants compared to untreated nails, with effects observable from the first week.

In this study on Sprague-Dawley rats, 0.60 mg/kg doses of L-Se-methylselenocysteine and sodium selenite were associated with liver toxicity and reduced sperm motility, while Se-enriched peptides showed no observable adverse effects up to 0.60 mg/kg.

In a study on hair loss treatment, researchers found that a serum containing Cinchona succirubra extract and caffeine improved hair density and reduced hair loss in individuals with acute telogen effluvium after 16 weeks of use, with significant improvements observable after just 4 weeks.

This study examined a 7-year-old girl with trichomegaly of the eyelashes, showing no significant underlying or observable cause, suggesting a spontaneous occurrence.

Among adult male rats, this study found that combined exposure to lithium carbonate and lead acetate over 28 days led to synergistic cardiotoxic effects, evidenced by oxidative stress, ECG abnormalities, and molecular markers of increased apoptosis, despite no observable structural damage to myocardial tissue.

In this study, phenylthiocarbamide intake was associated with hair graying in rats, while switching to tap water led some rats to regain their original fur color, suggesting dietary factors influence pigmentation.

This study found that participant self-assessments suggested greater improvement in the texture and wrinkles of facial skin treated with PRP compared to normal saline, though dermatologist ratings showed no significant difference.

This study found that hypaphorine alters cytoskeletal organization in Eucalyptus globulus root hairs, contributing to reduced root hair elongation by possibly disrupting vesicle delivery needed for growth.

In this study, injecting chimeric RNA–DNA oligonucleotides into mice skin caused a temporary mutation in keratin 17, altering hair morphology, but the mutation was transient due to genetic compensation or cell replacement.

This review discusses the use of zebrafish larvae as an alternative model for studying ototoxicity, facilitating large-scale screening for otoprotective compounds, but reports no new clinical results.

In this study on tolerant rats, maternal and developmental toxicity from levo-alpha-acetyhnethadol hydrochloride were observed at all doses, without specific fetal toxicity or teratogenic effects.

In this study, researchers found that black holes with primary Proca hair exhibit distinctive optical properties, including a two-boundary shadow structure and additional inner rings, offering novel observational signatures and potential insights into strong-gravity environments.

This study found that topical application of the HDAC1/3 inhibitor Vorinostat promoted hair regrowth in a mouse model of alopecia areata and influenced the hair cycle in normal mice.

This study found that in mice, wool structure deteriorates as a malignant tumor develops, suggesting potential uses in cancer diagnostics.

In this study, Taiwanese men with androgenetic alopecia who took 1 mg/day of finasteride for a year experienced slowed hair loss progression and increased hair growth, with minimal adverse effects reported.

In this study, researchers developed a novel computational framework using deep reinforcement learning to identify strategies for cellular reprogramming in gene regulatory networks, showing its effectiveness in a model of immune response against infection.

In this study, 70% of female androgenetic alopecia patients who did not respond to standard minoxidil experienced clinical improvement after switching to a propylene glycol-free, witch hazel-based 5% minoxidil sulfate solution, with the treatment also being well-tolerated.

In this study, platelet-rich plasma treatment showed minimal effectiveness for Alopecia Areata but was more effective than no treatment, with a 20% improvement observed compared to 3.3% in the control group.

This review discusses the relationship between vitamin K and osteoarthritis, noting that while lower vitamin K levels are associated with increased osteoarthritis, the effects of vitamin K supplementation on the condition remain unclear due to a lack of clinical trials.

This study found that a five-dimensional model of personality perception from men's facial photographs better captures the complexity of face perception than the traditional two-dimensional Valence-Dominance model, highlighting overlaps with personality structures known from differential psychology.

This study conducted a genome-wide association meta-analysis using UK Biobank data to explore genetic correlations with perceived youthfulness, revealing traits linked to this perception among both male and female participants.

This study applied semantic text-mining to identify phenotypes linked to over 6,000 diseases, demonstrating that these phenotypes can accurately identify known disease-associated genes, creating a human disease network based on phenotypic similarity.

Classifying hair diseases, like alopecia, is difficult and needs more research to understand their causes.

This meta-analysis utilized genome-wide association data to explore the genetic traits related to perceived youthfulness across different sex groups in the UK Biobank, incorporating factors like facial aging and lifestyle habits, but the abstract does not report specific results.

In this study, 5% topical minoxidil was observed to promote hair regrowth in some patients with androgenic alopecia, while no regrowth was noted in patients with alopecia areata.

In this study, increased corticosterone from chronic stress prolonged hair follicle stem cell quiescence in mice, inhibiting regeneration, but restoring Gas6 expression overcame this inhibition.
