This review outlines the development, applications, and challenges of microneedle-based drug delivery from 2000-2019, particularly highlighting fabrication techniques, but reports no new clinical results.

This review discusses various substances that can impact male fertility and stresses that products should be confirmed 'sperm-safe' through rigorous testing, not assumptions; it reports no new study results.

This review highlights promising recent advances in therapies for epidermolysis bullosa, including gene therapy and stem cell approaches, but reports no definitive cures and emphasizes the need for further research.

This review explores various tissue regeneration technologies, highlighting how skin substitutes have significantly improved healing success rates for burn injuries, and examines cell-based therapies aimed at reducing scar formation and improving burn management.

In this review, researchers examined how needle gauge and length impact the viability of human stem cells during injections, emphasizing the balance between minimizing tissue trauma and preserving cell viability to optimize clinical protocols.

This study found that the natural polymer-based hydrogel Gel/SA@PL released growth factors in a controlled way, which enhanced tissue regeneration and minimized scarring in the healing of diabetic wounds.

This review explores the challenges of treating chronic wounds and highlights regenerative medicine as a promising approach, emphasizing the roles of growth factors, stem cell therapies, and novel regenerative treatments in improving wound healing and tissue regeneration.

This study identified new geometric and mechanical parameters for curly and kinky/coily hair, which may inform more effective personal care products tailored to these hair types.

This study used quantitative methods to identify new geometric and mechanical parameters of curly and kinky/coily hair, aiming to improve classification and develop better personal care products for these hair types.

The document recommends a multidisciplinary approach and experience sharing to advance facial feminization surgery as a medical field.

This study reported that alcoholic cirrhosis patients with zinc deficiency and skin lesions showed rapid symptom improvement with oral zinc sulfate treatment, confirming the diagnosis.

This review summarizes the application of microneedles in treating various skin diseases and highlights challenges like low drug loading, noting no new clinical results are reported.

This research highlights that engineered mice lacking the vitamin D receptor show multiple health issues similar to human vitamin D deficiency, underscoring the widespread impacts of the vitamin D endocrine system.

This paper reviews the diagnostic criteria, etiological factors, and treatment approaches for PCOS, highlighting the importance of considering metabolic issues such as insulin resistance and obesity, but reports no new findings.

This article reviews the design and objectives of the Rotterdam Study, as well as summarizes major findings, without reporting new results.

This study found that fibroblast growth factor 9, initially secreted by γδ T cells, plays a key role in modulating hair follicle regeneration in mice after skin wounds.

This review discusses the role of epidermal and other adult stem cells in skin repair, focusing on their potential therapeutic applications for non-healing wounds and other skin disorders, but reports no new research results.

This study found that removing PPARγ specifically from mouse adipose tissue led to severe fat loss, insulin resistance, diabetes, and associated metabolic abnormalities.

In this study, cross-sex hormone therapy affected hair growth patterns differently, with estrogen reducing hair growth in male-to-female transsexuals and testosterone increasing it in female-to-male transsexuals; however, male typical hair diameters were not fully reached in the latter group after 12 months.

In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This study found that mouse skin CD4(+) memory T cells are in equilibrium with the circulation under steady state but increase in specific clusters in response to infection or inflammation.

This study observed that quiescent label-retaining cells in the intestine, identified by Paneth cell markers, can switch to a proliferative state and activate Bmi1 expression during tissue injury, contributing to tissue regeneration.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

The researchers reported that dsRNA from damaged skin activates TLR3, promoting hair follicle regeneration, while TLR3-deficient animals fail to initiate this process, suggesting potential therapeutic approaches for hair neogenesis.

This study found that the protein MIM is crucial for maintaining cilia and Sonic hedgehog signaling in mesenchymal cells by counteracting Src-mediated phosphorylation of Cortactin, impacting hair follicle formation.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

This study suggests that the postnatal loss of hair follicle formation in wounds may be due to elevated Wnt/β-catenin activation in the dermis, affecting fibroblast function in mice.

This study found that β-catenin signaling increases in newly born glial cells in the cortex after traumatic brain injury in mice, suggesting potential targets for enhancing recovery through the Wnt/β-catenin pathway.

Dermal exosomes with miR-218-5p boost hair growth by controlling β-catenin signaling.
