This study found that the molecular structures of α-keratin and collagen in a 2,100-year-old female cadaver's hair and tendon were preserved, while fibrous molecule aggregations were altered.
research Characterization of a Test for Invasive Breast Cancer Using X-ray Diffraction of Hair—Results of a Clinical Trial
This study found that the combination of mammography and hair X-ray diffraction increased sensitivity for detecting breast cancer compared to using each method alone.
research Genomic prediction and genome-wide association studies of morphological traits and distraction index in Korean Sapsaree dogs
This study assessed breeding value estimation methods for Korean Sapsaree dogs, finding varied accuracy across BLUP approaches and identifying significant genomic regions affecting traits like body height and hair length. The researchers suggest these findings can enhance breeding strategies for this culturally significant breed.
research Limits of Visual Detection for Finasteride Polymorphs in Prepared Binary Mixtures: Analysis by X‐ray Powder Diffraction
research Exploring a biological tissue from atomic to macroscopic scale using synchrotron radiation: example of hair.
This study used advanced analytical techniques to reveal that proteins and lipids are distributed unevenly in hair, with distinct structural differences depending on their location within the fiber.
research Aplikasi Konsep Difraksi dalam Bidang Kesehatan
This review discusses applications of light diffraction in healthcare, highlighting its use in LASIK procedures, optogenetics, and measuring hair diameter, but reports no new results.
research An infant with congenital micrognathia and upper airway obstruction was diagnosed as Hutchinson-Gilford progeria syndrome caused by a novel LMNA mutation: Case report and literature review
In this study, the researchers reported a new case of Hutchinson-Gilford progeria syndrome with a novel LMNA mutation and successful surgical intervention for airway obstruction.
research Structural change of keratin protein in human hair by permanent waving treatment
This study found that permanent waving treatment partially disrupts the α-helical structure in human hair microfibrils, primarily during the initial reduction phase, rather than just affecting disulphide bonds.
research Attempted construction of minoxidil: carboxylic acid cocrystals; 7 salts and 1 cocrystal resulted
Made 8 minoxidil samples; 1 cocrystal, 7 salts formed.
research Fourier Transform Infrared Attenuated Total Reflection Analysis of Human Hair: Comparison of Hair from Breast Cancer Patients with Hair from Healthy Subjects
In this study, hair samples from breast cancer patients showed increased β-sheet structures and lipid content, with spectral markers successfully identifying cancer in a blind test but also producing false positives.
research Effect of shampoo, conditioner and permanent waving on the molecular structure of human hair
This study found that shampoo and conditioner do not alter hair's molecular structure, while perming treatments significantly affect keratin and intermediate filament structures due to bond alterations.
research Structural changes in the trichocyte intermediate filaments accompanying the transition from the reduced to the oxidized form
Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.
research Measurement of hair growth
Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.
research Nucleation and growth of macrofibrils in trichocyte (hard-α) keratins
This study suggests that varying intersheet interactions may explain the differences between the two polymorphic forms of macrofibril assembly in Merino wool and hair.
