This study found no evidence that the tested hair dye ingredients undergo hepatic metabolism to reactive oxidized metabolites in human liver microsomes and hepatocytes.

This study identified seven compounds from Cercidiphyllum japonicum twig extracts, including a newly discovered flavonoid, marking the first time these specific compounds have been isolated from this genus.

This study found that a more liberal intake of restricted amino acids in patients with methylmalonic acidemia resulted in improved growth and fewer illness episodes.

This review examines the potential of alpha-ketoglutaric acid as an anti-aging agent and for treating age-related diseases, emphasizing its metabolic, immune, and cosmetic benefits but reports no new clinical trials.

In this in-vitro study, researchers found that shampoo-induced coacervates structurally resemble cationic polymers and contain anionic surfactants that may stimulate the scalp upon exposure to water.

This study found that novel androgen antagonists incorporating a carborane moiety showed anti-androgenic activity comparable to flutamide in a laboratory setting.

This study identified the same N-terminal and C-terminal amino acids in human and horse hair as previously found in wool and feather keratin.

This study investigated the morphology and growth mechanisms of spherical crystal aggregates of minoxidil in various alcoholic solvents, finding that a n-butanol–ethyl acetate mixture produces unique spherulite aggregates with improved powder characteristics.

Transamidases are present in the epidermis but their exact role is unclear.

This study proposes a new method to selectively isolate keratin-associated proteins and keratin from human hair, suggesting that KAPs may support keratin fibers in hair structure.

In this study, novel substituted benzoyl benzoic acids and phenylacetic acids were potent and selective inhibitors of human steroid 5alpha-reductase type 2, with one compound showing promising bioavailability in rats for potential clinical evaluation.

This study found that chemically modifying human hair through esterification or disulfide reduction and alkylation affects the hair's viscoelastic properties, including stability, integrity, and response to moisture.

This study found that chronic ethanol exposure and withdrawal alter the expression and function of GABA-A receptors in rat hippocampal and cerebellar neurons, suggesting different roles for these receptors in controlling tonic inhibition.

This study found that incorporating Canavalia ensiformis lectin into alginate and carboxymethylcellulose films enhanced angiogenic factor expression, suggesting these biopolymer films could be an effective alternative for wound treatment.

This study suggests that Acrotrema arnottianum, a herb used in traditional medicine, contains biologically active metabolites like squalene and α-Tocopherol. It showed antibacterial effects against Staphylococcus aureus and antifungal properties against Candida albicans, while demonstrating antioxidant activity.

This study investigated the formation of a specific chemical crosslink in hair proteins and explored the role of transamidase enzymes in hair follicles.

Using a special solvent can make Cacumen Platycladi essential oil more effective for treating hair loss.

This study reports that the newly developed SA-Ca(II) hydrogel has tunable mechanical properties, high biocompatibility, and potential applications in wearable protections and stimuli-responsive electronics.

In this study, researchers found that increased hydrogen sulfide levels in Arabidopsis disrupted actin dynamics through S-sulfhydration, leading to the depolymerization of actin filaments and inhibited root hair growth.

This source explores melatonin's roles beyond circadian rhythm regulation, reporting its benefits in skin conditions like dermatitis, melasma, alopecia, psoriasis, and skin aging due to its antioxidant, anti-inflammatory, and immunomodulatory properties, while highlighting the need for more trials on optimal dosing and long-term safety.

This thesis developed stimuli-responsive nanocarriers, demonstrating their potential for targeted genetic material delivery with reduced toxicity and diagnostic applications, and explored pH-sensitive nanogels for effective skin drug delivery and monitoring.

Progesterone increases alcohol tolerance and withdrawal anxiety, while DHEAS prevents them.

In this study, carboxymethylalanyl disulfide keratin was shown to effectively prevent hair damage during repeated bleaching and permanent waving treatments.

This study evaluated new aqueous gel formulations of minoxidil without irritants and found that the calcium alginate gel showed the best performance in terms of drug release and skin permeation.

This study found that azelaic acid entrapped in transethosomes exhibited enhanced antidermatophyte activity and improved treatment outcomes in guinea pig models of dermatophytosis compared to free azelaic acid.

This article highlights the versatility and potential of alginate and its derivatives in tissue engineering applications, discussing their properties, modification techniques, and various uses in enhancing tissue healing, bone regeneration, and cell growth.

In this study, introducing the rat OTC gene into spf-ash mice led to increased OTC activity and normalized hair growth and biochemical markers like urinary orotic acid and serum citrulline, partially correcting the symptoms of OTC deficiency.

This study found that the CYP3A4 rs4646437 genotype was significantly associated with ALT elevation in Japanese patients undergoing asunaprevir plus daclatasvir therapy for chronic HCV infection, suggesting genotyping may help in monitoring patients safely.
