research Comparison of Artificial Sebum with Human and Hamster Sebum Samples
Artificial sebum L closely mimics human sebum for drug delivery research.
research In Silico Modelling of Transdermal Delivery of Macromolecule Drugs Assisted by a Skin Stretching Hypobaric Device
The simulation showed that hypobaric pressure improves drug delivery through the skin, but stretching alone doesn't fully explain the increase.
research A Composite Model for the Transport of Hydrophilic and Lipophilic Compounds Across the Skin: Steady-State Behavior
The model better predicts how water-loving and fat-loving substances move through the skin by including tiny pores and hair follicle paths.
research Degradation of Hair Surface: Importance of 18-MEA and Epicuticle
18-MEA and cationic surfactants can restore and maintain hair's hydrophobic nature, improving its beauty and feel.
research External Lipid Function in Ethnic Hairs
African hair has the most lipids, while Caucasian hair is more hydrated and stronger.
research Contribution of the Hair Follicular Pathway to Total Skin Permeation of Topically Applied and Exposed Chemicals
The hair follicle pathway significantly affects how easily water-loving chemicals pass through the skin.
research Development of a Two-Dimensional Model for Predicting Transdermal Permeation with the Follicular Pathway: Demonstration with a Caffeine Study
Researchers developed a model that shows hair follicles increase skin absorption of caffeine by 20%.
research Measurement of Steroid Hormones by Liquid Chromatography-Tandem Mass Spectrometry with Small Amounts of Hair
A new method accurately measures steroid hormones in a few hair strands and could help study chronic stress and hair loss.
research Effect of Tocopheryl Polyethylene Glycol Succinate on the Percutaneous Penetration of Minoxidil from Water/Ethanol/Polyethylene Glycol 400 Solutions
Adding TPGS to minoxidil solutions can improve skin penetration and retention, especially in water and PEG 400-based solutions.
research Prevalence of Polycystic Ovary Syndrome in Unselected Black and White Women of the Southeastern United States: A Prospective Study
PCOS affects a similar percentage of Black and White women in the Southeastern United States.
research Prevalence of Polycystic Ovary Syndrome in Unselected Black and White Women of the Southeastern United States: A Prospective Study
PCOS affects about 4% of women in the southeastern U.S. equally across Black and White populations.
research Treatment of Obstructive Sleep Apnea Improves Cardiometabolic Function in Young Obese Women with Polycystic Ovary Syndrome
Treating sleep apnea in young obese women with PCOS can improve heart health and insulin sensitivity.
research Absorption Sites of Orally Administered Drugs in the Small Intestine
Different factors affect where drugs are absorbed in the small intestine, which is important for effective medication use.
research Penetration and Distribution of Three Lipophilic Probes in Human Skin Focusing on the Hair Follicle
Medium lipophilic substances penetrate skin best, and adding ethanol can increase delivery to hair follicles.
research Original Research—Endocrinology: Comparison of the Steady-State Pharmacokinetics, Metabolism, and Variability of a Transdermal Testosterone Patch Versus a Transdermal Testosterone Gel in Hypogonadal Men
The testosterone patch and gel are both effective, but they have different absorption patterns and effects on hormone levels.
research Normal Pubertal Development in Daughters of Women With PCOS: A Controlled Study
Daughters of women with PCOS generally experience normal puberty but may have more body hair and different body fat distribution.
research Effect of Finasteride in Idiopathic Hirsutism
Finasteride significantly reduces hair growth in women with idiopathic hirsutism.
research Relationship Between Contact Time of Applied Dose and Percutaneous Absorption of Minoxidil From a Topical Solution
Longer contact time increases minoxidil absorption, but doesn't affect metabolism.
research Effects of Finasteride, a 5 Alpha-Reductase Inhibitor, on Circulating Androgens and Gonadotropin Secretion in Hirsute Women
Finasteride reduces dihydrotestosterone, increases testosterone, and may treat hirsutism in women.
