This source critically examines Bruce Ames's influential contributions to biochemistry, particularly his theories on oxidative stress and mitochondrial DNA damage in aging, while acknowledging current challenges to his work and highlighting his lasting impact on the fields of mutagen screening and public health.

This study found that applying dinitrochlorobenzene (DNCB), a contact allergen, led to hair regrowth in patients with alopecia areata, while croton oil did not have the same effect.

This study suggests that topical procyanidin B-2 is safe for use as a hair growth agent, as it showed no mutagenic effects or significant irritation in a series of toxicological tests.

This letter to the editor shares concerns about possible systemic effects from topical dinitrochlorobenzene therapy in a 25-year-old man treating alopecia areata.

This study found that finasteride caused adverse effects on liver, kidney, and heart tissues in female mice, raising concerns about its potential use in females for treating androgenetic alopecia.

This study found that rice bran oil extracted by supercritical CO2 can be considered non-genotoxic based on in vitro and in vivo test results, despite some chromosomal aberrations observed under specific conditions.

This review evaluates the efficacy and safety of topical sensitizers in treating alopecia areata but reports no new clinical findings.

In this study, high doses of Lepidium sativum seeds extract were reported to cause toxicity and tissue damage in animals, suggesting the need for careful use under medical supervision.

This review discusses the potential of cathelicidins in treating skin conditions but highlights significant challenges, including unclear clinical efficacy, safety concerns, and bacterial resistance, that must be addressed for successful medical application.

This study found that a topical plant worm extract significantly accelerated hair regrowth in mice without apparent toxicity or side effects.

This study investigated the extracellular polysaccharides from the edible green alga Parachlorella sp. BX1.5, finding that they have potential applications in cosmetics and health products due to their stability, antioxidant properties, and effects on hair growth in mice.

This study suggests that the oncogene c-Myc can induce DNA damage by increasing reactive oxygen species, potentially overriding p53 and contributing to genetic instability in cancer cells.

This study found that the K6/ODC transgenic mouse model is highly sensitive to identifying genotoxic carcinogens, showing 100% concordance with traditional rodent bioassays.

Azathioprine's effectiveness and safety require careful monitoring and more research, especially regarding its use with corticosteroids and the role of TPMT status in patients.

In this study, DNA cross-linking agents used in cancer therapy were found to cause unintended hyperplasia and fate mis-specification in normal epithelial stem cells through inflammasome activation in dermal fibroblasts.

This review examines topical immunotherapy for severe alopecia areata, noting that diphencyprone and squaric acid dibutylester are non-mutagenic options with similar efficacy but different practical considerations, and reports no new clinical results.

This study identified several compounds from traditional Chinese medicines that may inhibit prostaglandin D2 synthase, potentially providing promising candidates for treating androgenic alopecia with minimal adverse skin reactions.

This review discusses the use of contact sensitizers for topical immunotherapy in dermatological conditions such as alopecia areata and viral warts, but it reports no new clinical findings.

This study suggests that natural molecules like curcumin, EGCG, barringtozenol, and finasteride may be effective inhibitors for VEGFR, potentially offering a cancer chemoprevention alternative to pazopanib.

In this study, using a novel topical androgen receptor suppressor, fluridil, significantly increased the percentage of growing hairs in males with androgenetic alopecia without systemic absorption or adverse side effects.

This study highlights that improving medical professionals' knowledge of hair cosmetics can enhance patient adherence to alopecia treatments and reduce health risks from incorrect use of hair products.

This review discusses the preclinical findings on cyproterone acetate and suggests that while it has a low potential cancer risk for patients, its tumor effects in female rats may involve both genotoxic and mitogenic mechanisms.

This study found that the nutraceutical product DERM decreased the pro-inflammatory cytokine IL-6 in mesenchymal stem cells under in vitro conditions.

This article is a collection of book reviews in the International Journal of Cosmetic Surgery and Aesthetic Dermatology and presents no new clinical findings.

Mitochondria may influence how cells respond to radiation, affecting nearby non-irradiated cells.

This study reports that treatment with X-rays or procarbazine induced dose-dependent mutations in melanocytes in mouse hair follicles, showing similar mutation rates to previous methods.

This protocol details a method for inducing skin cancer in mice through chemical carcinogenesis, which studies cutaneous malignancies but does not report new findings.

Diphencyprone initially increases mouse hair growth, then slows it, possibly due to changes in specific protein levels.

This article discusses a proposed "Darwinian" model of carcinogenesis and emphasizes that cancer prevention involves more than avoiding mutagens, as gene-environment interactions are complex and non-linear.

This review discusses the preclinical and clinical data on teriflunomide for multiple sclerosis, highlighting its selective action on immune cells without causing clinical immune suppression, and provides no new clinical results.
