This paper reviews the state of knowledge on injectable cryogels, highlighting their unique properties such as shape-memory and mechanical integrity, which allow for minimally invasive delivery via needles and potential applications in oncology and regenerative medicine.

New hair after alopecia areata can be thinner and change color but usually keeps the same shape.

In this study, eight patients with hereditary vitamin D-resistant rickets who share a specific VDR mutation showed improved clinical symptoms except alopecia after up to 11 years of treatment.

This study compared hormone levels between oriental and Caucasian men, finding that while oriental men share similar plasma testosterone levels, their 17-oxosteroid excretion is lower, which may influence beard growth differences.

This study explored the creation of 3D-printed baricitinib pills using polylactic acid and found that the doughnut-shaped tablets increased surface area and drug release, with 59% released from the higher concentration pill over 24 hours.

This report describes a case where dermoscopy of shed hair helped diagnose post-COVID acute telogen effluvium by revealing depigmented club-shaped bulbs, highlighting its potential as a noninvasive diagnostic tool.

This study found that despite some differences, homoeopaths and izinyanga in KwaZulu-Natal share similar views on managing acne vulgaris, both considering it a symptom of deeper issues.

This chapter reviews various metrics for measuring sales performance, including sales effectiveness, market share, customer retention, and more, but reports no new research findings.

This case report describes a 21-year-old man with alopecia areata presenting as a U-shaped hair loss pattern resembling Hamilton grade VII male-pattern baldness, with no signs of inflammation or related conditions.

This minireview discusses a proposed model of the vitamin D receptor that explains how 1alpha,25(OH)2D3 can mediate both genomic and rapid responses through different ligand shapes and cellular locations, without presenting new research findings.

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 found that FM dyes are effective markers for tracing live Merkel cells in in vitro experiments, as they remain visible for at least seven days and highlight cell shape better than quinacrine.

This study found that the growth of hair ice on dead wood requires the biological activity of a winter-active fungus, specifically Exidiopsis effusa, which shapes and stabilizes the ice structures.

This review explores the similarities between wound healing, palatogenesis, and orofacial clefting, suggesting these processes share common pathways and genetic regulatory mechanisms, but reports no new experimental results.

This review discusses the potential of protein-based cosmetics, including keratin-based particles and fusion proteins, to improve hair properties such as strength and shape, but it reports no new clinical results.

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 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 article discusses aesthetic concepts in facial volume restoration but reports no new clinical results, highlighting strategies for mimicking natural facial shapes and the importance of highlights and shadows in aging.

In this study, researchers identified Tenascin-C as a marker for touch dome keratinocytes, which maintain themselves and can develop into Merkel cells following injury, showing they share molecular traits with various epidermal keratinocytes.

This review describes the edge out punch for follicular unit excision, which may reduce follicle transection with its thicker walls and internal bevel design compared to other punch shapes, but reports no new clinical results.

This study observed that good surgical outcomes for secondary cicatricial alopecia were achieved in 18 patients, with method selection influenced by the size, location, and shape of alopecia.

This study found that using ablative fractional CO₂ laser therapy combined with FUE treatment in patients with post-traumatic eyebrow scars and defects improved follicular survival rates and resulted in well-defined eyebrow shapes.

This study examined the microscopic characteristics of hair or feather in five animal drug components of the Shenrongbian pill, identifying distinctive medulla cell shapes and hair cuticle patterns for each component.

This article reviews key factors in reconstructing natural-looking hairlines in hair restoration surgery, focusing on the location, shape, and types of grafts, without presenting new findings.

In this study, a method using nano-sized iron particles successfully captured images of sub-dermal hair follicles, showing comparable size and shape to those removed from the skin.

In this study, treating hair with thioglycolic acid was found to alter disulfide bond patterns in keratin-associated proteins, shifting them from an ellipsoidal to a near-spherical shape.

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.

This study examined hair classification based on geo-racial origin, observing that Caucasian and Mediterranean hair differs morphologically from African or Asian hair, with differences in density, thickness, and fiber shape contributing to varied hair characteristics such as color and curliness.

This study investigated the hair of German shepherd dogs, revealing variations in color, shape, and band patterns across different body regions, while all hair types shared similar anatomical structures such as continuous, vacuolated medullas and cuticular scales with smooth or rippled margins.

In this study, researchers analyzed hair from different regions of Malvi cattle and found significant variations in color, shape, and band pattern, although the medullary index remained consistent between 0.50 and 0.60 across the samples.
