This study found that administering botulinum toxin A via Flex-PADs to mouse footpads inhibited sweating similarly to traditional injections, suggesting a promising patient-friendly delivery method for hyperhidrosis treatment.

In this review, the authors emphasize that phenotypic heterogeneity in genetic systems and human diseases is influenced by stochastic fluctuation and network topology, proposing that ultrasensitivity and threshold effects explain this variability, which may inform strategies for preventing and treating genetic diseases.

This study found that the moisture content of human hair significantly influences the type of fracture under tensile loading, with low or high humidity levels leading to smooth fractures and intermediate humidity resulting in step fractures.

This study found that a hypomorphic mutation in the Hr gene contributes to the development of diet-induced pruritic atopic skin in mice, particularly when combined with dietary deficiencies of polyunsaturated fatty acids and starch.

In this study, researchers investigated the impact of a bioactive peptide derived from amphibians on hair follicle regeneration in diabetic skin, focusing on its potential to enhance wound healing and reduce infection risk.

This study observed that dandruff is linked to a weakened immunoprivilege in hair follicles, with reduced Langerhans cells and increased epidermal CD4+ and CD8+ T cell infiltration.

This study found that microspicule cosmetics with low-molecular-weight peptide complexes significantly improved skin whitening, pore condition, and skin barrier function over four weeks compared to a non-microspicule formulation.

This study observed unique ultrastructural changes in a 4-year-old girl with pili trianguli et canaliculi that may affect hair shaft surface characteristics due to inner root sheath alterations.

This study found that TRPV3 activation in human sebocytes inhibits lipid synthesis and triggers proinflammatory cytokine expression, suggesting a role in the pathogenesis of dry skin-associated inflammatory dermatoses.

This case study identified Trichophyton rubrum as the cause of trichophytia profunda acuta in a patient using nested PCR, suggesting an alternative diagnostic approach when KOH tests and cultures fail.

This case study discusses a 36-year-old female diagnosed with a facial variant of eruptive vellus hair cyst, confirmed by skin biopsy, and highlights the importance of considering this condition in the differential diagnosis of asymptomatic facial papules.

This study identified a high-risk allele in the PLCD1 gene associated with hereditary trichilemmal cyst formation, proposing a monoallelic two-hit mechanism as the underlying genetic pathogenesis.

This case report describes a unilateral contact dermatitis caused by shoe dye containing 4-aminoazobenzene, which was confirmed with patch testing, highlighting its atypical presentation.

This study found super-contraction in the guard hairs of fur-bearing animals, likely due to oxidation in living animals, primarily affecting white and red foxes without prior heat or chemical treatment.

In this study, stress hormone CRF was found to inhibit hair growth, suggesting that the HPA axis is functional in human dermal papilla cells and contributes to hair loss under stress conditions.

This study suggests that a position effect disrupting TRPS1 expression may be linked to hypertrichosis in both Ambras syndrome in humans and a similar phenotype in Koa mice.

This study estimates that young adults have about 230,000 tactile afferent fibers innervating their skin, with density varying by region and decreasing with age.

In this in-vitro study, researchers found that shampoo-induced coacervates structurally resemble cationic polymers and contain anionic surfactants that may stimulate the scalp upon exposure to water.

This review discusses pyrene excimer nucleic acid probes for detecting biomolecules and protein-DNA interactions and reports no new experimental findings.

This case series describes Erythromelanosis follicularis faciei et colli in five Indian patients, suggesting it may be more common than currently reported.

Red dots on the upper chest may be an early sign of certain types of hair loss.

This study characterized the mouse profilaggrin gene, finding it structurally identical to its human counterpart, and noted differences in protein-coding regions that could impact epidermal differentiation.

This study reports that in vitro experiments suggest a new biomagnetic cross-talk between red blood cells and human hair could be a factor in red blood cell deformation.

This study found that epidermal stem cells in nonglabrous skin are connected to the distal end of the arrector pili muscle, which may play a role in epidermal renewal and wound healing.

This report found follicular red dots in patients with scalp pigmentary disorders, suggesting they might be linked to the scalp's vascular structure and may have implications for conditions like discoid lupus erythematosus.

This study explored non-invasive methods for monitoring low molecular weight biomarkers on the skin's surface, concluding that certain amino acid ratios, such as Phe/Trp, could serve as potential indicators of skin inflammation and cancer.

This study found that epidermal growth factor receptor and mitogen activated protein kinase inhibitors down-regulate PD-L1 expression in human hair follicles, which may contribute to sterile folliculitis in treated patients.

This study observed that psychological factors and serum levels of zinc, folate, and vitamin B12 may contribute to the development of trichodynia.

This study established a novel in vivo "whisker follicle microinjection assay" using mouse whiskers to evaluate hair growth and pigmentation effects of various chemicals and proteins, identifying minoxidil, ruxolitinib, and RSPO1 as growth promoters, while deoxyarbutin inhibited pigmentation and Nbl1 emerged as a growth inhibitor.
