This study demonstrated that molecular dynamics simulations of keratin could effectively model the mechanical properties of hair, aligning well with experimental data, especially when conducted in vacuum conditions.

This study reports that expressed mouse type Ia and type IIa trichocyte keratins were successfully assembled into intermediate filaments in vitro, while also suggesting that disulfide bond cross linking enhances their stability.

In this study, hair shafts from trichothiodystrophy patients with ERCC2 mutations revealed abnormal cuticle structures and protein imbalances compared to normal hair shafts.

In this study, researchers found that TSPyV T antigens can disrupt normal cell differentiation and proliferation in hair follicles and interfollicular epidermis, possibly contributing to trichodysplasia spinulosa pathology.

This study confirms that the proposed universal model for hard α-keratin structure applies to all known forms across various mammalian species.

This study reported detailed three-dimensional ultrastructural observations of human hair and hair follicles using a modified preparation method, including morphological differences in hair bulb cell layers and surface projections on root sheath cells.

This study found that cationic lipid-based formulations enhanced the delivery of large molecules into hair follicles in human scalp skin, with potential to reach pharmacologically active concentrations in the hair bulb.

This study observed that the Raman spectra of human hair cuticle vary with polarization and direction of signal collection, identifying certain spectral bands as markers sensitive to the structural changes in keratin secondary and tertiary structures.

This study found that pen-type microwells enhanced hair follicle germ formation by promoting cell assembly, suggesting microwell array geometry significantly influences in vitro hair follicle development.

This study presents a two-photon imaging method to visualize low-threshold mechanoreceptor axon terminals in live mouse forepaw skin, enabling repeated high-resolution imaging to study sensory circuits during development and adulthood.

This study found that micro-computed tomography (micro-CT) was highly effective for analyzing the cross-sectional geometry of hair fibres, including the medulla in highly curled hair, but less effective than scanning electron microscopy for surface details.

This study found that smaller mesoporous silica particles (400-600 nm) accumulated in skin furrows, suggesting their potential as carriers for enhancing the delivery of topical medications like metronidazole.

This study found that keratinocyte stem cells in mouse skin are closely related to side population or BCRP1-positive cells based on their localization and marker expression.

This study identified Sciellin, a new protein precursor to the cornified envelope in keratinocytes, with unique solubility properties hinting at its potential role in envelope assembly.

USB videodermatoscopes are a practical and affordable alternative for diagnosing skin conditions.

This article reviews various microscopy techniques and their applications in dermatology but reports no new experimental results.

This study observed that in chicken skin, large-scale differences in gene expression between feathered and scaly skin are controlled by enhancer-driven uniform expression, while small-scale differences within individual feathers are associated with chromatin looping.

This study reports the first instance of skin autotomy in mammals, specifically in African spiny mice, and suggests they may possess a greater regenerative capacity than previously understood, possibly offering insights for regenerative medicine.

This study found that MAP-2 is intensely expressed in the companion layer of the hair follicle, suggesting its potential importance to follicle integrity and possible involvement in some types of alopecia.

This article presents a comprehensive overview of hair microscopy techniques and their diagnostic potential for systemic and cutaneous disorders, emphasizing its usefulness in resource-limited settings and highlighting the underutilization of this non-invasive method due to lack of awareness.

This study investigates calcium and phosphorus accumulations in the hair of mummies from the Taklamakan desert and debates their exogenous or endogenous origin.

This study reported the development of a workflow that combines SIMS and X-ray elemental mapping techniques for multimodal imaging at the single cell level, successfully applied to visualize elements, metals, and lipids in porcine skin without loss or delocalization.

This study presents additional data suggesting that the absence of nerve endings in certain segments of human hair follicles influences the asymmetrical distribution of electrical charges, as indicated by no precipitation of Potassium Ferricyanide crystals.

This study observed that mink dermal collagen fibrils undergo structural changes during the hair cycle, with increased fiber thickness and bundle density as minks grow.

This study identified numerous size polymorphisms in the human ultrahigh sulfur KAP4 genes due to intragenic sequence variations, suggesting these polymorphisms may have arisen through deletions and duplications during evolution.

This study found that Cupiennius salei spiders have specialized mechanosensitive hairs on their legs that adaptively respond to joint movements during walking, suggesting a proprioceptive function.

This study observed in mouse skin that trichohyalin granules in hair follicles transform into filamentous structures as inner root sheath cells differentiate and cornify.

This study demonstrates that MPM-FLIM multimodal imaging can effectively assess the delivery and dissolution of zinc pyrithione particles in human skin follicles using different application techniques.
