research Analysis of Hormone Antagonists in Clinical and Municipal Wastewater by Isotopic Dilution Liquid Chromatography Tandem Mass Spectrometry
Researchers developed a method to detect hormone-blocking drugs in wastewater and found them in Beijing's sewage, suggesting they can survive sewage treatment.
research Sex Steroid Synthesis in Human Skin In Situ: The Roles of Aromatase and Steroidogenic Acute Regulatory Protein in the Homeostasis of Human Skin
Human skin produces sex hormones like estrogen and testosterone, influenced by ARO and StAR, which may affect skin elasticity and hair growth.
research Evaluation of Hair Density and Hair Diameter in the Adult Thai Population Using Quantitative Trichoscopic Analysis
Thai people's hair density decreases with age and varies by scalp area, but hair thickness stays the same regardless of age or scalp area.
research Intermediate Hair Follicles: A New, More Clinically Relevant Model for Hair Growth Investigations
Intermediate hair follicles are a better model for studying hair growth and testing hair loss treatments.

research Regeneration of Hair Follicles Is Modulated by Flightless I (Flii) in a Rodent Vibrissa Model
Flightless I protein affects hair growth, with low levels delaying it and high levels increasing hair length in rodents.
research A Fibrous Hybrid Patch Couples Cell-Derived Matrix and Poly(L-Lactide-Co-Caprolactone) for Endothelial Cells Delivery and Skin Wound Repair
The new patch made of cell matrix and a polymer improves wound healing and supports blood vessel growth.
research Insulin Promotes Corneal Nerve Repair and Wound Healing in Type 1 Diabetic Mice by Enhancing Wnt/β-Catenin Signaling
Insulin helps heal corneal wounds and nerves in diabetic mice by activating the Wnt signaling pathway.
research Increased Polyamine Concentrations in the Hair of Cancer Patients
Hair can be used to measure cancer-related chemicals noninvasively.
research CRISPR/Cas9-Mediated Disruption of Fibroblast Growth Factor 5 in Rabbits Results in a Systemic Long Hair Phenotype by Prolonging Anagen
Disrupting the FGF5 gene in rabbits leads to longer hair by extending the hair growth phase.
research Charge Density Alterations in Human Hair Fibers: An Investigation Using Electrostatic Force Microscopy
The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.
