This study provides genomic and epigenomic insights into the white wax scale insect, highlighting high methylation levels and differential hormone profiles linked to its sexual dimorphism and developmental differences.

This article discusses the development of a standardized assessment scale for hair transplant outcomes, emphasizing multiple parameters that contribute to an aesthetically pleasing result and reports no new clinical findings.

This article discusses the structure and protective function of pangolin scales, emphasizing their composition of α-keratins and β-keratins, and highlights evolutionary keratin diversification in tetrapods; it reports no new empirical findings.

This study found that TET2 plays a tumor-suppressive role in preventing squamous cell carcinomas by regulating 5-hydroxymethylcytosine levels, suggesting therapeutic potential for DNA methylation dynamics.

This study developed new graded visual scales integrating macroscopic and trichoscopic images for assessing the severity of androgenetic alopecia in men and women, potentially aiding in more objective disease evaluation.

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.

Alopecia areata greatly affects the quality of life for children and their families.

This study identified distinct gene expression programs in keratinocytes responsible for forming hard scales and soft interscale epidermis in chickens, revealing conserved differentiation genes similar to those in human skin.

This study presents the Italian adaptation of the ECR-M16 to assess attachment dimensions in cancer outpatients and notes that its factor structure is partly similar to the original.

This study observed that atopic dermatitis severity was associated with higher eosinophil counts and FLG variants, suggesting distinct endotypes that may require tailored treatment approaches.

This study used social media data to identify more and milder COVID-19 symptoms than clinical research and to map symptom evolution over 27 months, highlighting differences between the Delta and Omicron periods.

In this study, the researchers reported that using a biodegradable ECM scaffold for large-area wound regeneration accelerated wound coverage and improved hair follicle neogenesis by activating the adaptive immune system.

In this study, researchers found that the original four-factor model of causal illness attributions in the IPQ-R did not fit a Chinese sample, and instead identified a two-factor model focusing on psychological attributions and risk factors.

This study investigated the mechanical response of the human hair cuticle to strain and found that cuticular deformation directly corresponded with fiber elongation, revealing significant molecular-level changes in disulfide crosslinks but maintained structural stability, highlighting the role of the cuticle in stress resistance.

In this animal study, the researchers found that biodegradable extracellular matrix scaffolds accelerated wound healing and enhanced hair follicle neogenesis in mice, suggesting a role for immune systems in tissue regeneration.

In this study, analyzing over 400 million tweets revealed a broader and milder spectrum of COVID-19 symptoms than clinical research, and illustrated symptom evolution and co-occurrence throughout the pandemic.

This study found that the Massachusetts General Hospital Hairpulling Scale has acceptable internal consistency and divergent validity for assessing Trichotillomania severity, but demonstrated inadequate test-retest reliability and mixed convergent validity.

This study found that local refinement of hair follicles into higher order patterns can occur without the core planar cell polarity system, but global alignment with body axes requires its function throughout development and regeneration.

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 found that finasteride use is not significantly associated with an increased risk of depression or suicide, based on Mendelian randomization analysis and COX regression analysis in a large UK Biobank cohort.

Photobiomodulation did not significantly improve hair density in dogs with alopecia X.

This study validated a Spanish version of the Hair Specific Skindex 29 scale for assessing quality of life in women with female androgenetic alopecia, showing similar psychometric properties to the original.

This study found that 42% of healthy men aged 18-49 in a community setting experienced moderate to extensive male pattern hair loss.

This study found that the molecular structure of hair is more sensitive to synchrotron X-ray radiation than its supramolecular architecture, indicating potential concerns for biological analyses using such radiation.

This study validated the Black Identity, Hair Product Use, and Breast Cancer Scale (BHBS) as a tool to measure social and cultural factors related to hair product use and perceived breast cancer risk in Black women.

This study developed an efficient method for converting polymeric procyanidins into high-purity oligomeric procyanidins using a semisynthetic approach combined with separation techniques.

Tailoring COVID-19 measures to risk levels in the military improves health and readiness.
