In this study, heavy nighttime physical exercise delayed the circadian phase of clock gene expression by 2 to 4 hours in a professional fighter, suggesting potential implications for managing circadian disorders.

This study found that nano-sized minoxidil formulations significantly increased skin penetration and follicular drug delivery for alopecia areata treatment, compared to conventional ethanol-based solutions, and demonstrated effective controlled release over six hours.

This paper reviews the role of pharmacokinetic/pharmacodynamic modeling in drug development, emphasizing its application for drug dosing guidance, safety resolution, and therapeutic monitoring improvement, without presenting new clinical results.

This study reported that extended-release valproate significantly reduced seizure frequency and improved quality of life in epilepsy patients over six months, despite some adverse effects like weight gain and tremor.

Hair fibers may have a unique, non-protein sheath not previously identified.

Hair testing is a reliable method for detecting workplace drug use when done with proper sample preparation and confirmation.

This study discusses how dermatological issues in athletes can arise from or be exacerbated by mechanical trauma, infections, and environmental factors, highlighting the importance of thorough history and examination to differentiate these from other skin conditions.

This review describes the roles of polysaccharides in antitumor, antiviral, and anti-inflammatory activities and introduces methods for their isolation and purification, reporting no new research results.

This study found that the pH-sensitive hydrogel HECHA13, containing isoliquiritigenin, effectively inhibited the growth of Propionibacterium acnes and showed promise for transdermal delivery in acne treatment.

This study found that liposomes coated with cationic polymers, chitosan and Eudragit EPO, showed improved physicochemical stability and enhanced skin diffusion of aciclovir and minoxidil compared to uncoated liposomes.

This study examined different polymersome systems for topical finasteride delivery and found that chitosan-decorated C7 polymersomes may enhance skin retention and provide controlled drug release compared to non-decorated systems in laboratory settings.

This study suggests that artificial sebum L may serve as an effective substitute for human sebum in drug transport studies, due to its similar physicochemical properties.

This study concluded that polymeric nanoparticles effectively targeted hair follicles for drug delivery, but the organogel formulation did not enhance their penetration into the hair shaft.

This chapter reviews surface plasmon resonance (SPR) methodology and its applications in basic science and human disease without reporting new clinical results.

This study established a stable formulation for caffeine nanocrystals in specific solvent mixtures, which could be used to test their potential for enhanced hair follicle targeting and penetration.

This study found that microRNA levels in hair shafts were significantly decreased in scleroderma patients compared to normal subjects, suggesting they may serve as effective biomarkers.

This study found that adapalene-loaded solid lipid microparticles may enhance targeted drug delivery into sebum due to their similarity to sebum components, although both this formulation and a standard cream showed equivalent follicular penetration.

In this study, researchers developed a new self-administered finasteride delivery system using powder-carrying microneedles that improved hair growth efficacy and addressed safety concerns compared to topical finasteride gel by allowing sustained intradermal release of the drug for three days with a single application.

This study found that a novel effervescent formulation significantly increased minoxidil sulphate accumulation in hair follicles and skin compared to a standard minoxidil solution.

This study found that using drug microplates in transdermal finasteride films enhances aqueous solubility and skin permeation compared to films with pure finasteride.

This study found that drying finasteride solvates at 85 °C for one day produced a metastable anhydrous form.

This research investigated aqueous alginate-based hydrogels for delivering minoxidil and reported that using hydroxypropyl-β-cyclodextrin (HP-β-CD) with molar substitution 0.65 significantly enhanced minoxidil's solubility and skin permeability without damaging the epidermis, suggesting potential as an alternative to commercial minoxidil solutions.

This study found that the MXD/HP-β-CD GEL formulation promoted greater hair growth and improved gene expression related to hair growth in male rats compared to MXD solution or control groups.

This study found that a 2% polyherbal phyto-complex cream containing aqueous extracts of Trichosanthes cucumerina and Abrus precatorius effectively promoted hair growth in preclinical tests, comparable to minoxidil 2%.
