480-510 / 1000+ resultsresearch Mapping the hair density, thickness, and volume in normal and androgenetic alopecia subjects with the digital microscope
Hair density and thickness decrease in specific scalp areas in people with androgenetic alopecia.
research Evaluation of glucuronide metabolite stability in dried blood spots
Dried blood spots can be as stable as frozen liquid samples for storing certain metabolites.
research Clinical Case Notes. Lipoid proteinosis: a rare disorder with pathognomonic lid lesions
A baby boy with 13q deletion syndrome had eye cancer, a woman's vision improved after stopping a breast cancer drug, a man developed cataracts from using Propecia, and a rare skin disorder called Lipoid Proteinosis was discussed. Also, a tool called OCT is useful for diagnosing macular diseases.
research Female patients complaining about hair loss: documentation of defective scalp hair dynamics with contrast-enhanced phototrichogram
The study concluded that a special imaging technique showed women with hair loss have slower hair growth and a faulty hair replacement cycle.
research Human hair keratin network and curvature
Curly hair shape is due to uneven growth patterns in the hair follicle.
research Determination of illegal adulteration of dietary supplements with synthetic hair-growth compounds by UPLC and LC-Q-TOF/MS
The new method accurately detects illegal hair-growth drugs in dietary supplements.
research Étude PCPT : les biais attendus et leur gestion
Systematic end-of-trial biopsies are the most reliable way to assess outcomes.
research LB1605 3D imaging of cleared ex vivo normal human skin, skin appendages and psoriasiform skin lesion using light-sheet microscopy
The conclusion is that using light-sheet fluorescence microscopy with a special solution can effectively create detailed 3D images of human skin for dermatological research.
research Human hair form. Morphology revealed by light and scanning electron microscopy and computer aided three-dimensional reconstruction.
Hair follicle shape determines hair type: curly, straight, or in-between.
research 701 Rethinking alopecia scores: Correlating measures of hair loss with established photographic scoring systems
The conclusion suggests that a new system for measuring hair loss could be created using automated analysis of photographs.
research Gonadotropin releasing hormone agonist (nafarelin) test to differentiate gonadotropin deficiency from constitutionally delayed puberty in teen-age boys--a clinical research center study.
The nafarelin test can reliably distinguish between gonadotropin deficiency and delayed puberty in teenage boys.
research Glycation of hair protein in the assessment of long-term control of blood glucose.
Hair glycation levels can indicate long-term blood sugar control.
research Pigmentary-Hair-Follicle Unit Under Innovative Pathologic Investigation - Is There a Potential to Improve Outcome of Sensor-Controlled Scalp-Cooling?
research Functional endoscopy techniques for tracking stem cell fate
Endoscopic imaging can improve tracking of stem cells in the body.
research Use of γ-Glutamyl Transpeptidase Activity as a Marker of Hair Cycle and Anagen Induction in Mouse Hair Follicles
research INTERACTION OF α-MELANOCYTE-STIMULATING HORMONE, MELATONIN, CYCLIC AMP AND CYCLIC GMP IN THE CONTROL OF MELANOGENESIS IN HAIR FOLLICLE MELANOCYTES IN VITRO
α-MSH and cyclic AMP boost melanin production, while cyclic GMP and melatonin reduce it.
research Comparative Study of the Effect of UV- VS. Gamma Radiation on Human Hair
Hair fluorescence intensity can measure radiation exposure effectively.
research An in vivo method for the detection of somatic mutations at the cellular level in mice
A new method can detect mutations in mice by observing changes in hair follicle cells.
research Quantitative Studies on Human Hair Growth(II). Correlation between Subjective Grading and Objective Measurements of Hair Growth.
The study concluded that certain hair growth measurements are good indicators of baldness severity and provide a more accurate assessment than subjective grading.
research Diagnostic Modalities in Trichology - An Update
New hair and scalp disease diagnosis methods are important for correct treatment.
research Linear alopecia in pediatrics: RCM and dermoscopy reveal diagnostic cues
RCM and dermoscopy help identify different types of hair loss in children.
research Association Between Hair Cortisol Levels AndKeratoconus: A Prospective Study
Higher cortisol levels might be linked to worsening keratoconus.
research The Use of Ovarian Vein Sampling to Lateralize a Virilizing Leydig Cell Ovarian Tumor
Ovarian vein sampling can effectively locate ovarian tumors when imaging is unclear.
research Automated digital image analysis (TrichoScan) in male patients with androgenetic alopecia; comparison with manual marking of hairs on trichoscopic images
TrichoScan needs optimization as it underestimated hair density by 38.9% compared to manual counting.
research Enzyme-linked immunosorbent assays for doping control of 5α-reductase inhibitors finasteride and dutasteride
New tests detect finasteride and dutasteride in urine quickly and easily.
research Comparative GC-MS Based In vitro Assays of 5α-Reductase Activity Using Rat Liver S9 Fraction
The S9 fraction with GC-IDMS is effective for measuring 5α-reductase activity.
research Development of a New Grading Scale for Evaluating Overall Hair Density
A new reliable scale improves accuracy in measuring hair density and treatment response.
research A quantitative ultra-performance liquid chromatography high-resolution mass spectrometry analysis of steroids from human scalp hair
The method can measure multiple steroids in human hair to study long-term steroid metabolism, especially in newborns and children.
research ASSESSMENT OF THE SEVERETY OF ANDROGENETIC ALOPECIA USING TRICHOSCOPIC FEATURES AND THEIR CORRELATION WITH HISTOMORPHOLOGICAL FINDINGS
Trichoscopy is useful for assessing androgenetic alopecia severity but can't determine hair loss stage alone.
