This review discusses the potential of 3D bioprinting technologies for tissue regeneration, drug evaluation, and drug delivery systems, but reports no new findings.

This study suggests that changes in expressed transcripts and splice isoforms may explain the transition from curly to straight fleece in Chinese Tan sheep as they age.

This study found that the absence of sebaceous glands may be an early factor in the development of keratosis pilaris, leading to hair shaft and skin barrier abnormalities, independent of filaggrin mutations.

In this study, a genetic analysis identified a pathogenic variant in the ALOXE3 gene associated with non-bullous congenital ichthyosiform erythroderma, and the patient's response to antifungal treatment highlights the risk of cutaneous fungal infections.

This study found that in SAMP8 mice, phenotypic changes in outer hair cells or the stria vascularis, possibly due to oxidative deficiencies, may predict variability in age-related hearing loss before outer hair cell loss occurs.

This study reported that a new deep learning algorithm using Mask R-CNN improved hair follicle classification accuracy by 4 to 15%, suggesting potential clinical application for enhanced hair loss diagnosis.

This review discusses the growing role of colorimetric sensors in food safety, highlighting their potential to enhance detection accuracy and manageability, while also noting challenges such as environmental interference and the need for further industrial validation.

In this scoping review, researchers observed that while AI-assisted trichoscopy holds promise for standardized assessments of hair and scalp disorders, its clinical translation is limited by small proprietary datasets, inconsistent validation protocols, and a scarcity of real-world clinical studies.

In this study, researchers used transcriptome sequencing to identify 1543 differentially expressed genes between cashmere and normal goats, implicating several signaling pathways and key regulators in the distinct gene expression profiles linked to cashmere fiber production, which advances understanding of cashmere goat genetics.

This study found that immune privilege is preserved in hair follicles of nonsegmental vitiligo patients compared to those with alopecia areata, potentially protecting follicular melanocytes from autoimmune attacks.

In this study, researchers analyzed French social media posts and found that alopecia areata profoundly impacts patients' quality of life, affecting them physically, psychologically, socially, and financially, often driving them to seek support online.

In this animal study, rosehip seed oil applied to the skin of mice promoted hair regrowth by accelerating hair follicles' transition from resting to growth phases and increased hair follicle density, bulb size, and skin thickness, suggesting potential as a treatment for hair loss.

In this study, the researchers found that a high percentage of young women with alopecia had deficiencies in Vitamin D, zinc, ferritin, and haemoglobin levels, suggesting the importance of testing these factors in such cases.

This study found that scalp melanoma often occurs in areas with androgenetic alopecia, and patients without alopecia might experience a later diagnosis due to hair coverage, leading to potentially worse outcomes.

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.
