This study found that cystatin M/E strongly inhibits human cathepsin V and cathepsin L via distinct non-overlapping sites, suggesting an important role in human epidermal differentiation and hair follicle morphogenesis.

This review discusses the role of acyl-CoA binding protein (ACBP) in the epidermal barrier, noting that its disruption in mice is linked to skin and fur abnormalities; it reports no new clinical results.

This case study found that a 7-year-old girl's crystalline cataract had sulfur-containing amino acids likely cystine, and was associated with abnormal hair conditions.

This study suggests that combining Silybum marianum extract, Manganese PCA, and Lespedeza capitata extract may help improve hair growth and anchorage by targeting specific signaling pathways in human dermal papilla cells.

The researchers investigated a Maine Coon cat with suspected classical Ehlers-Danlos Syndrome and discovered a heterozygous deletion in the COL5A1 gene, underscoring the value of whole-genome sequencing for precise veterinary diagnostics.

This study reported that Cacumen Platycladi extract significantly reduced hair loss and increased hair density in a 12-week clinical trial, suggesting it may be a safe and effective natural treatment.

This chapter offers detailed histopathologic insights into various pilosebaceous unit diseases, discussing diagnosis without reporting new results.

This study found that genes in the human keratin-associated protein 1 family may have evolved mainly through gene duplication of cysteine-repeat motifs.

This report describes an unusual case of proliferating trichilemmal cyst with trichoepitheliomatous change in a young woman, differing from its typical presentation in elderly women.

Substance P helps restore skin thickness and cell renewal when sensory nerves are reduced.

This study found that multifunctional peptide-based materials derived from Crassostrea gigas may promote scarless dermal wound healing without affecting intestinal flora through both topical and oral administration.

This study found that colchicine treatment significantly reduced hair fiber elongation in cultured hair follicles and altered protein expression and activity in dermal papilla cells, suggesting a role for the ubiquitin-proteasome system in its effects.

This study observed Malassezia hyphae in the keratotic plugs of healthy individuals, which contrasts with previous findings of these hyphae primarily in lesions of pityriasis versicolor patients.

This study suggests that Ptprq in the hair bundles may exist as multiple isoforms that are differentially expressed throughout development and affect the organization of stereocilia in the chick inner ear.

UV-enhanced trichoscopy helps diagnose hair shaft disorders like pili annulati.

The correction fixes an image mistake in the original publication, but the findings on the hair treatment's effectiveness are unchanged.

Cathepsin L deficiency causes hair and skin issues in mice.

This study found cell-specific variations in POMC mRNA and peptide expression in murine skin, suggesting that PC1 and PC2 convertases contribute to differential POMC processing.

This study suggests that true binary and ternary inclusion complexes were formed between finasteride and 2-hydroxypropyl-ß-cyclodextrin, with or without the addition of specific polymers.

This study investigated the extracellular polysaccharides from the edible green alga Parachlorella sp. BX1.5, finding that they have potential applications in cosmetics and health products due to their stability, antioxidant properties, and effects on hair growth in mice.

In this study, CTCF was found to play essential roles in epidermal differentiation and skin barrier formation, simultaneously acting as a suppressor of epithelial inflammatory responses in mouse skin.

This study found that the biosynthetic pathways of coumestans in Eclipta prostrata are derived from acetate and shikimate pathways, while 3,5-di-O-caffeoylquinic acid biosynthesis originates exclusively from the shikimate pathway.

This case report describes white piedra infection of the scalp hair with a synergistic bacterial infection in two US native sisters, highlighting its relevance in diagnosing scalp hair concretions despite its rarity in North America.

In this study, PINCH-1 gene loss in mouse epidermis led to detachment from the basement membrane, thickened skin, and hair loss, with findings suggesting PINCH-1 plays a role in keratinocyte adhesion through both ILK and EPLIN pathways.

This study found that BBS7 expression is crucial for maintaining Sonic hedgehog signaling activity and periodontal ligament homeostasis, suggesting its downregulation in occlusal hypofunction affects cell migration and angiogenesis.

This study found that DHHC13 is crucial for hair anchoring and skin barrier function, with its deficiency in Zdhhc13(skc4) mice leading to cyclic alopecia and skin abnormalities due to cornifelin deficiencies.

This chapter reviews the clinical presentation of Polycystic Ovary Syndrome and its differentiation from other conditions, but reports no new clinical results.

This case study presents an 81-year-old woman diagnosed with Cronkhite-Canada syndrome and discusses the importance of recognizing its clinical and histopathological features for timely and accurate diagnosis.

This study reports that a novel multi-compound Blend, tested on ex vivo human hair follicles, promotes hair growth by enhancing elastin deposition and dermal papilla inductivity more effectively than isopropyl cloprostenate, suggesting benefits through elastogenesis and modulation of Wnt signaling.

This study found that oral collagen peptides increased expression of genes associated with epidermis development and the hair cycle in hairless mice, providing insights into their potential skin benefits.
