This review discusses the dermatologic needs and care considerations for transgender patients undergoing gender transition, highlighting the unique role dermatologists can play, but it does not report new clinical results.

In this study, researchers used an evolutionary-rate-based method to identify genetic elements associated with reduced hair in mammals, finding a dichotomy between accelerated coding sequences and noncoding regulatory elements influencing hair growth.

This study identified key molecular differences between Long and Short hair type cashmere goats, suggesting hair type differentiation is linked to structural assembly and follicle remodeling.

This research discusses the diverse populations and specialized roles of dermal fibroblasts in human skin, highlighting their distinct interactions and contributions to skin structure, without presenting new clinical findings.

This study identified non-structural proteins in preschool children's scalp hair that suggest potential biomarkers for brain development, immune function, and stress response with heritability and age-related differences.

Men are increasingly interested in cosmetic treatments that enhance masculinity and address aging without downtime, with tailored approaches for different ethnicities and a focus on hair restoration and body contouring.

This review outlines the histological structures of the skin, highlighting species and regional differences in dermal absorption and obstacles encountered in toxicological assessments due to epidermal thickness variability, contact dermatitis reactions, and stem cell vulnerabilities.

This article reviews the structure and chemistry of hair across ethnicities and how these factors affect hair properties and treatment responses, but reports no new research findings.

This publication provides a standardized nomenclature for classifying microscopic lesions in laboratory rat and mouse skin, aiming to harmonize international toxicological research.

This study described a Scottish family with hidrotic ectodermal dysplasia featuring variable symptoms such as hypo/oligodontia, thin hair, and heat tolerance, and concluded they exhibited overlapping traits with Clouston syndrome.

The Naked gene in mice causes abnormal sebaceous glands and disrupts hair follicle organization.

The document explains how hair follicles develop, their structure, and how they grow.

This study found that polycaprolactone (PCL) in facial fillers led to more cell proliferation and vascular activity than hyaluronic acid (HA) in Wistar rats, suggesting enhanced tissue regeneration effects with PCL.

This study suggests that hair transplantation to new nonscalp sites affects the growth and survival rates of transplanted hairs, while the diameter remains unchanged.

This study found that the structure and mineral content of dromedary camel hair, specifically the medulla patterns, medulla index, and elemental composition, change with age, revealing differences among camels aged 1 year, 3-5 years, and 8-10 years.

This study found that CD34+ cells from adipose tissue may enhance hair morphogenesis and participate in blood vessel formation in reconstituted skin tissues of mice.

This study found that Raman spectroscopy has potential for detecting biophysical differences in basal cell carcinoma compared to normal skin structures, supporting its future use in Mohs surgery.

This study found that while overall differences are minimal, oscillatory punches are significantly more effective than rotary punches for cases requiring hair extraction through soft scalps or deeper punches, and following structured guidelines can improve outcomes.

This study demonstrated that CD anisotropy effectively distinguishes between two polymorphs of finasteride with nearly identical electronic circular dichroism spectra, using imaging and simulated spectra to uncover unique signatures that traditional methods miss.

In this study of Angora goats, researchers found that HOXC13 and other genes were overexpressed during the active hair growth phase, suggesting a role in mohair structure.

This study observed that hair fibers in older women become more curved with age, decreasing hair luster due to their disordered alignment and structural differences between the convex and concave sides.

This study introduces genital sex differentiation parameters (GSDP) to analyze sexual differences in external genitalia and perineum development in mice, revealing varied sensitivity to androgen inhibition in genital structures.

This study observed that lectin-binding patterns in skin appendage tumors reveal differences in sweat gland tumors compared to normal tissues, but pilosebaceous tumors maintained a similar lectin-binding pattern to their corresponding normal structures.

This study found that zebrafish and sticklebacks, despite differences in their tooth regeneration structures, share a similar genetic program during tooth regeneration, suggesting a conserved "successional dental epithelium" in vertebrates.

This study used atomic force microscopy to image surface structures of human epidermal melanocytes, hair follicle amelanotic melanocytes, and mouse melanoma cells, revealing differences in branch structure and granule distribution.

This review assesses existing knowledge about the 17q21.31 inversion polymorphism, highlighting its genetic structure differences across ancestries, associations with various diseases, and implications for precision medicine and drug discovery.

This study found that finasteride impaired object recognition memory and altered hippocampal dendritic structures in male 3xTg-AD mice, suggesting potential sex differences in Alzheimer's disease pathology.

This review addresses the effects of testosterone on brain development and examines both the established sex differences in brain functions and the debate surrounding structural dimorphism in neuropsychiatric conditions.

This study characterized the mouse profilaggrin gene, finding it structurally identical to its human counterpart, and noted differences in protein-coding regions that could impact epidermal differentiation.

This study found that by using an automated system to analyze skin histology, 108 structural features were significantly affected by age, and it identified four new aging biomarkers and notable sex-based differences in skin aging.
