This study found that women with PCOS had significantly higher levels of the pro-inflammatory chemokine MIP-1α compared to controls, suggesting an association with low-grade chronic inflammation, though the increase in MIP-1β levels did not reach statistical significance.

The authors concluded that establishing and standardizing methods for data collection are crucial to improving PCOS diagnosis and research due to challenges observed in data harmonization across diverse international cohorts.

This article discusses keratosis pilaris, a common skin condition often considered a normal variant, and reviews its associations, progression, and available treatments without reporting new clinical results.

This article reviews lichen planopilaris, its presentation, and treatment challenges, and emphasizes the need for more research into its pathogenesis and therapy efficacy; it reports no new findings.

This study found that selecting Angus cattle for early puberty reduced their prolactin levels, which may indicate a response to changing day length.

PMS nanoparticles improve damaged hair by protecting and restoring its surface and color.

This review discusses the potential relationship between lichen planus pigmentosus and frontal fibrosing alopecia, presenting a case study but reporting no new clinical findings.

This case report describes a patient with lichen planopilaris who experienced remarkable hair regrowth at a previously scarred area after treatment with low-dose naltrexone and platelet-rich plasma, following minimal response to other therapies.

This review discusses the pathophysiologic role of lysophosphatidic acid in the skin and reports no clinical results, suggesting pharmacological inhibition as a potential treatment for various skin disorders.

This study suggests that PLA2R1 overexpression in PMN affects the podocyte cycle and may involve an additional immune response, which could provide new directions for PMN treatment development.

This article reviews the potential uses of PDRN in regenerative and aesthetic medicine, noting promising results in various treatments but highlighting the need for further long-term studies to confirm their safety and effectiveness.

Certain peptides can prevent hair loss in young rats caused by a cancer drug.

In this study, dimeric peptide derivatives were shown to enhance the proliferation of human follicle dermal papilla cells in vitro, particularly promoting the ERK1/2 pathway, suggesting potential for developing peptide-based treatments for hair regeneration.

This study found that type II keratins in proliferating epithelial tissues are phosphorylated at a conserved motif during mitosis and stress, impacting keratin solubilization and reorganization.

This study suggests that geranyl acetate may offer protective, anti-inflammatory, and cytoprotective effects against PPD-induced toxicity in keratinocyte cells, indicating its potential as a plant-derived treatment.

In this study, finasteride was found to induce tissue-specific P-glycoprotein activity in the liver and kidney of rabbits after a 14-day treatment period.

This case report highlights a misdiagnosis of traction alopecia that progressed to lichen planopilaris in a patient of color, emphasizing the need to consider LPP in similar cases due to differing treatments.

This study reports significant hair regrowth in two alopecia areata patients resistant to intralesional corticosteroids after treatment with intralesional polydeoxyribonucleotide.

This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

Pioglitazone may help treat lichen planopilaris, but more research is needed.

This study found that polyquaternium-68 at pH 9 achieved the greatest hair deposition, while polyquaternium-44 demonstrated the best wash resistance at pH 6.

In this study, procyanidin B-2 and C-1 were found to promote hair growth by selectively inhibiting protein kinase C, supporting their potential use for hair-growing activity.

This study found that DK peptides demonstrated potent inhibition of 5α-reductase, suggesting they may be promising candidates for treating hair loss.

This study suggests that Foxn1 acts as a brake on PKC signaling in keratinocytes, thereby modulating the stages of differentiation by controlling PKC activity.

The new treatment improved keratosis pilaris symptoms and mood in 28 days.

This study found that epithelial keratin K 6 is associated with hyperkeratotic and ulcerated changes in the gastric pars oesophagea of pigs, suggesting epithelial proliferation plays a role in ulcer development.

The researchers reported that both finasteride and PM-9 competitively inhibit the 5 alpha-reductase enzyme in P. crustosum broth.

This study in a rat model found that dietary rehabilitation with a high protein diet reversed symptoms of kwashiorkor, suggesting a role for free radicals in its development.

This study found that overexpressing PKCδ in transgenic mice did not reduce squamous cell carcinoma development induced by UV radiation, despite its effectiveness against TPA-promoted cancer in these mice.

Martin-Perez et al. show that rapamycin's beneficial effects in a mouse model of Leigh syndrome are linked to the downregulation of protein kinase C.
