This study investigated the Mandarin duck as a model for understanding lifelong developmental changes, finding that male sail feather morphogenesis involves a combination of local morphogenetic programs, epigenetic regulation, and hormonal cues, with increased female estrogen levels observed before the mating season.

This study found that calprotectin induces complex multi-metal starvation responses in Pseudomonas aeruginosa, affecting its metal homeostasis pathways and resistance to polymyxin B.

In this mouse study, researchers found that dermal Wnt signaling/β-catenin activity is essential for fibroblast proliferation and initiating hair follicle formation by interacting with epidermal Wnt ligands.

The researchers reported that during early embryogenesis and larval development in Silurana tropicalis, inhibiting steroidogenic enzymes cyp19 and srd5beta affects genes related to thyroid and reproductive systems.

This study found that the tetracycline-regulated transcription system effectively controls conditional gene expression in the mouse epidermis, allowing suppression and activation of specific genes with doxycycline.

This study observed that during male silkmoth development, trichogen cells in olfactory sensilla undergo significant membrane recycling, contributing to sensillum structure formation in a precisely timed series of stages.

Hoxc13 is important for hair and tongue development by controlling hair keratin genes.

This case report describes a 17-year-old patient diagnosed with Netherton syndrome, characterized by pruritic dry skin, short brittle hair, and elevated IgE levels, treated with antihistamines and emollients.

This study outlines the complex structure and various functions of the skin, emphasizing its role as a barrier against external insults, a sensory receptor, and its importance in vitamin D synthesis.

This study found that upregulation of NFIC may enhance proliferation and osteogenic/cementogenic differentiation in rat dental follicle cells.

This study found that dietary yeast cell wall supplementation in broiler chickens increased certain immune responses compared to antibiotic treatments following immunization with sheep red blood cells.

This study found that men receiving enzalutamide and other androgen-deprivation therapies may be at increased risk for QT prolongation and torsades de pointes.

This study found that hair-type tissues in hedgehogs show higher enrichment of immune-related genes compared to spine-type tissues, suggesting that spines evolved to protect against injuries and infections.

This study found that a eupafolin nanoparticle delivery system improved water solubility and skin penetration, enhancing its antioxidant and anti-inflammatory effects against particulate matter-induced stress in skin cells.

In a case study, a 6-year-old Shih Tzu with both demodicosis and babesiosis showed improvement after treatment, which included medications like ivermectin and supportive care such as specialized shampoos and environmental spraying, evaluated up to the 21st day.

This study found that in a rat model, 14,15-EET may alleviate central poststroke pain by enhancing thalamic inhibition through neurosteroid signaling, potentially outperforming gabapentin in early-stage treatment.

In this study, the alcoholic extract DN106212 from Centipeda minima was shown to be more effective in promoting hair growth in C57BL/6 mice compared to dimethyl sulfoxide and tofacitinib, suggesting its potential as a natural hair growth agent.

This study found that a new deoxycholic acid derivative may offer a similar prostatoprotective effect to finasteride with lower toxicity in rat models.

This article discusses the potential role of oral DHEA, available as a 'dietary supplement' in the US, in COVID-19 morbidity and mortality, calling for clinical trials to assess its safety.

This study found that anagen hair follicles can quickly regenerate after radiation damage by forming new progenitor cells outside the bulge, bypassing the need for telogen entry.

This study found that JAK1 and JAK2 inhibitors increase β-catenin activity in human hair follicle cells, suggesting an additional therapeutic mechanism for treating severe alopecia areata.

This study demonstrated that ellagic acid promoted hair regrowth in a DHT-induced androgenic alopecia mouse model by inhibiting ferroptosis through the activation of the Wnt/β-catenin signaling pathway, suggesting its potential as a treatment for androgenic alopecia.

This study found that back skin mesenchyme from mouse embryos can induce hair follicle formation even before dermal condensate formation, but R-spondin-1 alone or with a Bmp receptor inhibitor was not sufficient for hair follicle induction.

This report describes a case of widespread Porokeratotic eccrine and hair follicle nevus in a 15-year-old woman with keratitis-ichthyosis-deafness syndrome, involving both eccrine ostia and hair follicle infundibula.

This study found that keratin immunohistochemistry suggests neoplastic cells in eccrine and apocrine poromas are closely related to dermal sweat duct cells, but cannot differentiate these poromas based solely on keratin patterns.

This study found that the EtOAc extract of Tridax procumbens aerial parts significantly inhibited rat paw edema and COX enzyme activity, suggesting its potential anti-inflammatory properties.

This study successfully isolated inner ear-specific exosomes from perilymph samples of sensorineural hearing loss patients using a novel immunomagnetic approach, enabling groundbreaking liquid biopsy diagnostics.

This study identified WNT10A as crucial for adult epithelial cell proliferation and differentiation, suggesting β-catenin pathway activation may help address regenerative defects in WNT10A mutation patients.

This study successfully synthesized novel cercidin analogues from Cercidophyllum japonicum, confirming their structure via NMR data. The researchers suggest these compounds could facilitate future antibiotic development by advancing structure-activity-relationship studies.

In this study, researchers found that mast cells in Erythema Toxicum lesions in newborns are actively involved in the immune response around hair follicles, but do not express the antimicrobial peptide LL-37.
