Keratin fibers in hair twist left-handed.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

This study used phytochemical screening and FTIR spectroscopy with PCA to reveal slight chemical differences between two varieties of Eclipta alba, providing a method for their effective discrimination.

This study proposed that the tiger tail phenomenon in trichothiodystrophy hair is caused by regular undulations of hair fibers, altering the optical properties seen under polarized light.

This study used a new multimolecular spectral method to uncover structural differences in hair keratin from individuals with androgenetic alopecia compared to healthy individuals, identifying potential biomarkers and providing insights for developing new treatments.

This study found that keratin intermediate filaments in the hair of patients with giant axonal neuropathy were structurally altered, resulting in hair that was stiffer, stronger, and more extensible.

This study developed PiSCES biosignatures that distinguished alopecia areata patients from controls, revealing enhanced basal TCR signaling and a potential disease-specific signaling network signature.

Human hair's structure makes it tough and resistant to breaking.

This article discusses themes in the molecular structure of hair and reports no new research findings.

Defective protein folding due to a mutation is key in ANE syndrome.

Human hair keratin has a 40% α-helix structure that changes to a random coil in 8 M urea.

This study developed and tested a new algorithm for analyzing coat and skin coloration in laboratory animals, using digital images and hierarchical color clustering, which effectively quantified color proportions and tracked changes over time without specialized software.

The method effectively analyzes human hair proteins, especially nonfilamentous ones.

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.

This study found that both AB(0) antigens and keratin phenotype can be determined from the same hair fragment using specific protein extraction and analysis methods.

This study found that hydrophilic carbon dots (Lys-CA-CDs) induced bovine serum albumin to form more wormlike fibrils, while inhibiting hen egg white lysozyme from forming hair-like fibrils.

Mice hair follicles take in the amino acid cystine.

This review discusses the use of hair microscopy in diagnosing hair-related conditions, highlighting techniques and common applications, but presents no new experimental results.

This study found that chromosomal microarray analysis identified copy number variations in 12% of patients with dysmorphic features and congenital anomalies, demonstrating its potential as a diagnostic tool, especially for rare CNVs and immune deficiency linked to the deletion of CTLA4.

This study reported that the calculated and experimental electronic and vibrational properties of minoxidil were in good agreement, providing detailed insights into its molecular structure and thermal behaviors.

This study proposes a new test for genome-wide association studies that incorporates Hardy-Weinberg equilibrium into SNP analysis, demonstrating improved power and interpretability over traditional methods, as evidenced by simulations and an alopecia study dataset.

This study utilized a fluorescence probe to evaluate cysteine formation on hair fibers, finding that optimal fluorescence emission occurred at pH 4.5.

This study found that while molecular hair structures were nearly identical across individuals, genetic factors seem to influence specific lipid compositions, as seen in identical-patterned hair from parent-child pairs and identical twins, but not fraternal twins.

This study found that lead treatment enhances the imaging of organized hair lipid structures, revealing their orientation and possible composition as lead and calcium soaps, with potential applications in various fields.

This study used in-lab hair samples to show that cut hairs found at a crime scene and on a suspect can be matched to confirm they were from the same individual.

This study discusses using SEM/EDX for elemental analysis of hair samples in forensic science but notes challenges in detecting certain trace elements from raw hair.

In this study, optical coherence tomography was used to produce 3D images of human hair, revealing that after chemical treatment with ammonium thioglycolate, the main hair structures were not identifiable due to damage.

In this study, researchers found that trichothiodystrophy hair brittleness is linked to abnormalities in sulfur content and structural organization, making it prone to breakage.
