research Cross-species sensitivity to a novel androgen receptor agonist of potential environmental concern, spironolactone
Spironolactone harms fish reproduction and is more potent in fish than invertebrates, needing environmental monitoring.
research Histopathological Study on Collagen in Full-Thickness Wound Healing in Fraser’s Dolphins (Lagenodelphis hosei)
Fraser's dolphins heal wounds exceptionally well, with their skin's collagen returning to normal after injury.
research Elastoinertial effects govern dynamic response of soft hair beds
Hair beds in fluid show nonlinear response due to viscosity, inertia, and elasticity.
research The Influence of Skin Structure on Permeability: An Intersite and Interspecies Comparison with Hydrophilic Penetrants
research Kinetics and Equilibrium of Solute Diffusion into Human Hair
Hair absorbs molecules differently based on their size, charge, and love for water, and less at higher pH; this can help make better hair products.
research Examining polyquaternium polymers deposition on human excised hair fibers
Certain polymers can stick to hair and increase volume, working best at a pH of 7 to 9.
research Can the Second to Fourth Digit Ratio (2D : 4D) Be a Marker to Determine Ankylosing Spondylitis Disease Activity?
The index to ring finger ratio may indicate disease severity in female ankylosing spondylitis patients, but not in males.
research An isolated, implausibly large effect in a case-control study of digit ratio (2D:4D) and male androgenetic alopecia: Comment on Unal (J Cosmet Dermatol 2018;17(3):545-548)
Digit ratio likely doesn't predict male hair loss.
research Mackerel-Derived Fermented Fish Oil Promotes Hair Growth by Anagen-Stimulating Pathways
Mackerel-derived fermented fish oil helps hair grow by activating growth pathways and increasing cell proliferation.
research Docosahexaenoic acid slows inflammation resolution and impairs the quality of healed skin tissue
High DHA levels delay wound healing and worsen skin repair quality.
research Preparation of human hair keratin/calcium alginate blend films
More human hair protein makes the films weaker and less clear.
research Low Heterozygosity and Historical Bottleneck Effect Depicted From the Genome Assembly of the Indus River Dolphin (Platanista minor )
The Indus River dolphin has low genetic diversity due to a past bottleneck and human impact.
research Hair-on-hair static friction coefficient can be determined by tying a knot
Tying a knot can measure hair friction, useful for medical applications.
research Second to Fourth Digit Ratio in Patients with Hirsutism and Its Correlation with Hormonal Assay
Finger length ratio is not linked to hirsutism or hormone levels.
research OPTIMIZATION OF COMPRESSIVE STRENGTH OF CONCRETE WITH PIG-HAIR FIBERS AS FIBER REINFORCEMENT AND GREEN MUSSEL SHELLS AS PARTIAL CEMENT SUBSTITUTE
Adding pig-hair fibers and green mussel shells to concrete can make it stronger.
research Digit ratio 2D:4D is a possible indicator for androgenetic alopecia in males
Finger length ratio may indicate male hair loss.
research Variations in the optical scattering properties of skin in murine animal models
Male mice have thicker skin, causing more light scattering than females.
research The Aqualon SLT: A novel device for measuring hair stiffness and lubricity
The Aqualon SLT device measures hair stiffness and slipperiness to evaluate hair treatments.
research 395 Wildfire air pollution and increased online search interest and clinic visits for psoriasis
Wildfire air pollution is linked to more online searches and clinic visits for psoriasis in adults after a delay.
research Validated LC-MS/MS Method for Simultaneous Quantification of Finasteride in Human Plasma
research Hair-on-hair static friction coefficient can be determined by tying a knot B Biointerfaces
Treating hair with 1M sodium hydroxide increases its friction, making it better for small medical knots.
research Evaluation of hair humidity resistance/moisturization from hair elasticity.
Polyquaternium-70 shampoo is best for reducing frizz.
research Is There an Association Between Male Alopecia Areata and the Ratio of Second to Fourth Finger Length?
A lower second to fourth finger length ratio may predict male alopecia areata.
research Rat steroid 5α-reductase kinetic characteristics: Extreme pH-dependency of the type II isozyme in prostate and epididymis homogenates
The activity of a specific rat enzyme in the prostate and epididymis is highly dependent on the acidity level.
research Finasteride affects the testicular physiology of gilthead seabream males
research Assessment of the Mean Platelet Volume-to-Platelet Count Ratio in Alopecia Areata: A Retrospective Case Control Study
The MPV/PC ratio can help assess disease activity in alopecia areata.
research Hair-Growth-Promoting Effects of the Fish Collagen Peptide in Human Dermal Papilla Cells and C57BL/6 Mice Modulating Wnt/β-Catenin and BMP Signaling Pathways
Fish collagen peptides can significantly promote hair growth.
research Determination of Solute Diffusion Properties in Artificial Sebum
Diffusion in artificial sebum is mainly influenced by molecular size and is much faster than in skin lipids.
research Localization of Zinc in a Dense Fiber-Connecting Piece Fraction of Rat Sperm Tails Analogous Chemically to Hair Keratin
Most zinc in rat sperm is in the tail, linked to structures similar to hair keratin.
