This narrative review explores gender differences in the epidemiology, risk factors, and effects of COVID-19, emphasizing the need for further analysis using comprehensive gender indicators to shape effective public health strategies and policies.

This study hypothesizes that curly hair is shaped by the contraction of the Arrector Pili Muscle within the follicle, potentially modifiable through muscle-relaxing treatments, but further research is needed to confirm this mechanism.

This study found that although progerin expression in mouse skin causes significant nuclear shape changes in keratinocytes, it does not result in alopecia or common skin abnormalities seen in human Hutchinson–Gilford progeria syndrome.

In this study, incorporating a novel amino acid compound into a hair-straightening formulation improved humidity-resistant straightening and enhanced the surface and mechanical properties of hair fibers, including increased bending stiffness, reduced friction, and better shape retention under high temperature and humidity conditions.

In this study, researchers used atomic force microscopy to capture and analyze morphological changes in the surface of healthy hair, identifying features such as pitting and rod-shaped macro-fibrillar elements, which could inform future research on hair conditions and care.

This study found that ablation of Tet2/Tet3 genes in skin epithelial cells altered hair shape and length, leading to hair loss, by affecting chromatin accessibility and gene expression related to hair follicle regulation.

This study found that disrupting Lm332 expression in mice changes keratinocyte genetic expression, alters cell shape, and disrupts epidermal homeostasis, despite some compensatory anchorage by hair follicle basal cells.

In this study, researchers used 3D printing combined with cryogenic crosslinking to develop gelatin/oxidized alginate scaffolds and found that adding 5% hydroxyapatite improved mechanical properties and osteogenic effects, enhancing bone tissue regeneration, though 10% hydroxyapatite offered no additional osteogenic benefits and reduced shape fidelity.

This chapter explores the evolving cultural and scientific significance of coffee, highlighting how traditional beliefs, brewing innovations, and globalization have shaped its consumption and cultural impact across different societies.

This review outlines recent advancements in droplet-based microfluidic technology using food-grade emulsions to create diverse delivery systems by controlling droplet size, shape, and dispersity, while also discussing challenges in scaling these processes from laboratory to industrial applications.

This review discusses the genetic and biological factors influencing hair curliness, revealing strong links to specific protein variations, and reports no new clinical results.

This study suggests moving away from using rigid racial categorizations and outdated typologies in favor of analyzing detailed trait patterns, providing a foundation for future research on human variation and hair traits in relation to population affinity.

This review discusses the history and composition of permanent hair waving products for different hair types and reports no new research findings.

This study found that HFV70 cryogels, made from Flammulina velutipes extract and hydroxyethyl cellulose, effectively promoted rapid hemostasis and tissue regeneration in full-thickness skin defects in rats, demonstrating improved hemocompatibility, cytocompatibility, antimicrobial, and antioxidant properties.

This case report describes a 25-year-old woman with alopecia areata and nail spooning, which regressed almost completely after treatment with oral corticosteroids.

A 9-year-old Hispanic girl has Uncombable Hair Syndrome, which may improve with age and biotin treatment.

This study found that incorporating Canavalia ensiformis lectin into alginate and carboxymethylcellulose films enhanced angiogenic factor expression, suggesting these biopolymer films could be an effective alternative for wound treatment.

In this study, KRTAP28-1 variants were associated with wool fibre diameter in sheep, suggesting potential as a gene marker for reducing fibre diameter.

This study identified a new ovine KRTAP21-1 gene variant in sheep, with wool yield affected by the variant, suggesting its potential as a genetic marker for improving wool production.

This study found that IBA-1-immunopositive macrophages in rat skin during wound healing show varied morphometric characteristics and peak in numbers at 2, 6, and 15 days post-injury.

Hard α-keratin in hair has a unique, nonordered structure, different from other fibers.

This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

This study found that thioglycolic acid molecules in hair treatments are primarily located in intrafibrillar unordered areas, where they redistribute disulfide bonds.

This study systematically examines how smart biomaterials used with DLP technology can enhance bioprinting in tissue engineering and regenerative medicine, while also identifying current challenges and future research needs.

This research reported that a newly developed dually crosslinked gelatin-alginate-based hydrogel scaffold enhances mechanical strength, promotes corneal tissue regeneration, and reduces scarring in rabbit models, suggesting potential applications in corneal tissue engineering.

This review highlights the lack of research on Afro-textured hair, emphasizing the need for better understanding of its genetic traits and molecular structure to develop more effective hair care solutions.

This study found that overexpression of the enzyme SSAT in a mouse model significantly reduced prostate tumor size and progression, suggesting it could be a promising strategy against prostate cancer.

This study found that utilizing a clinical pharmacist in perioperative urological services reduced surgical cancellations and resident overtime while improving service efficiency and financial sustainability.

In this study, researchers identified a highly reactive, isozyme-specific sequence for TGase 3, contributing to understanding its distinct functional role and activity distribution in the mouse epidermis.

This review discusses recent advances in developmental tissue engineering for regenerating ectodermal appendages like teeth and glands, emphasizing biomaterial selection and cell culture strategies, but reports no new experimental results.
