900-930 / 1000+ resultsresearch Hormonal profile and androgen receptor study in prepubertal girls with hypertrichosis
Prepubertal girls with hypertrichosis have more sensitive androgen receptors, leading to increased body hair growth.
research The Influence of Surgical Stress on Human Scalp Hair Fiber Dimensions
Surgical stress temporarily changes hair fiber dimensions, returning to normal after four weeks.
research Application of 3D Reflectance Confocal Microscopy: Melanocytic Proliferations as 3D Models; JAAD Supplemental Material
3D models from confocal microscopy improve melanoma detection on sun-damaged skin.
research Immunofluorescence analysis of the basement membrane zone components in human anagen hair follicles
The upper hair follicle is stable, while the lower part allows movement during hair growth.
research Analysis of Gene Expression in Isolated Single Hair Follicles: An Approach Using Semiquantitative Reverse-Transcriptase—Polymerase Chain Reaction
Researchers developed a new way to measure gene activity in single hair follicles and found that a specific gene's activity changes with different amounts and times of treatment.
research Usefulness of high-frequency ultrasonography in the assessment of alopecia areata – comparison of ultrasound images with trichoscopic images
High-frequency ultrasonography can be a useful tool for diagnosing different stages of alopecia areata, a type of hair loss.
research Microscopic sex-based differentiation of human scalp hair among university students in Nigeria
Male and female scalp hair differ in size, density, length, curliness, pigmentation, and cuticle preservation.
research Androgen regulation of a specific gene in hamster flank organs
Male hormones control a specific gene in hamster skin, with different hormones having varying effects.
research Body Composition and Characterization of Skinfold Thicknesses from Polycystic Ovary Syndrome Phenotypes. A Preliminar Case-Control Study
Women with PCOS have higher body fat and skinfold thickness, especially in the H-O-POM phenotype.
research Multiphoton microscopic imaging of rabbit dorsal skin
Multiphoton microscopy effectively images rabbit skin structures in detail without staining and shows differences from human skin.
research Structure and biochemistry of mammalian hard keratin
research Ultrastructure of the contrasting types of keratinization seen in the tail epidermis of the laboratory mouseMus musculus
Mouse tail skin has different keratinization near hair follicles and scales.
research Applications of Hair as a Record of Systemic Exposure to Cortisol
Hair cortisol content can indicate cortisol exposure and varies with age, puberty, and BMI in youth.
research Determination of steroid hormones in human hair as a retrospective biomarker with HPLC-MS/MS
A new method accurately measures long-term hormone levels in hair.
research Hair Restoration / Dow B. Stough /
Follicular unit transplantation, a hair restoration technique using small hair grafts, was pioneered by Bob Limmer in the late 1980s and is still widely used today with minor improvements.
research Transcriptome Profiling and Differential Gene Expression in Canine Microdissected Anagen and Telogen Hair Follicles and Interfollicular Epidermis
Different genes are active in dogs' hair growth and skin, similar to humans, which helps understand dog skin and hair diseases and can relate to human conditions.
research LC-APCI+-MS/MS method for the analysis of ten hormones and two endocannabinoids in plasma and hair from the mice with different gut microbiota
The method accurately measures hormones and endocannabinoids in mice, showing gut microbiota diversity affects these levels and may influence stress and reproductive systems.
research Hairless down-regulates expression of Msx2 and its related target genes in hair follicles
Hairless protein reduces Msx2 gene activity, affecting hair follicle development.
research Analysis of hair steroid hormone concentrations at different parts of the head by liquid chromatography-tandem mass spectrometry
Hormone levels in hair vary across the head, with the highest concentration of a key hormone linked to hair loss at the top.
research Histological characteristics of hair follicles at different hair cycle and in vitro modeling of hair follicle-associated cells of yak (Bos grunniens)
The study provides insights into hair growth mechanisms in yaks.
research Whole-genome bisulfite sequencing of goat skins identifies signatures associated with hair cycling
DNA methylation changes are linked to hair growth cycles in goats.
