This study developed and validated a sensitive liquid chromatography–mass spectrometry method to measure aristolochic acid‐I in rat plasma, successfully applying it to pharmacokinetic research.

In this study, daily treatment with ritlecitinib for up to 24 months led to significant reductions in high-severity alopecia areata SALT scores among patients aged ≥12 years, including those with severe forms such as alopecia totalis and universalis.

This case report describes a patient who developed a maculopapular rash after starting lithium treatment, highlighting the importance of monitoring skin reactions due to potential impact on treatment adherence.

This study reported that most patients with alopecia areata who responded to ritlecitinib treatment by achieving a SALT score ≤20, SALT score ≤10, or improvements in eyebrow and eyelash assessments at Week 24 maintained their responses through Week 48.

In this study, the use of two emollients significantly reduced itching severity in individuals with xerotic eczema, starting 30 minutes post-application, and improved skin moisture and lipid content over 14 days, while demonstrating good tolerance with few adverse events.

This review discusses evidence from recent clinical trials showing inclisiran effectively lowers LDL cholesterol levels in patients with cardiovascular disease, leading to its use in the UK despite not being approved by the FDA.

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.

In this study, liposome-encapsulated thioglycolic acid improved hair perming by enhancing the penetration of perm solutions, resulting in a stronger S-shaped wave and higher cysteine content compared to the control.

This case study reported a rare occurrence of lepromatous leprosy with Lucio phenomenon in a 50-year-old Indonesian living in Malaysia, highlighting the necessity for primary care practitioners, even in non-endemic areas, to recognize this serious leprosy reaction to prevent complications and transmission.

This study examined the stability of two 5α-reductase inhibitors in Tectona grandis extracts, finding that they are more stable in acidic environments and degrade rapidly under heat and light unless protected, suggesting the need for careful storage when developing anti-hair loss medications.

This study reports no new findings but provides corrected figures for the long-term safety and efficacy of ritlecitinib in treating alopecia areata from the ALLEGRO-LT phase 3 study.

This case report highlights that lipedematous scalp and alopecia areata may coexist and that precise diagnosis requires histopathologic examination.

In this Italian retrospective study, ritlecitinib 50 mg/day showed effectiveness and good tolerability for treating severe alopecia areata over 24 weeks, achieving significant hair regrowth particularly in adolescents, as well as improvements in eyebrows, eyelashes, nails, and quality of life, with mostly mild adverse effects.

This study observed that adolescents with alopecia areata receiving ritlecitinib 50 mg daily showed notable hair regrowth over three years, as seen in both clinician- and patient-reported outcomes. However, the decreased number of participants at later stages limits the findings.

This study found that formulating raloxifene in nano-lipid carriers significantly enhanced its permeation and cytotoxicity against cancer cells compared to raw raloxifene.

This study reports that retinol acetate inhibited the pro-oxidant effects of benoxaprofen on polymorphonuclear leucocytes in vitro.

This study found that RNase L acts as a regeneration repressor gene in mammals, as seen in Rnasel-/- mice which showed increased regenerative capacity and elevated Wound Induced Hair Neogenesis through enhanced IL-36α signaling, suggesting a tradeoff between regeneration and immune regulation.

This study reports that mutations in human L-PGDS affect the entrance and exit of ligands in its binding cavity, suggesting these residues play a role in ligand interaction processes.

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.

In this study, ritlecitinib showed sustained effectiveness and a favorable safety profile in treating alopecia areata in patients aged 12 and older over 24 months, with improvements observed in hair and eyebrow regrowth and patient satisfaction.

This study found that balneophototherapy improved skin lesions in a 13-year-old with severe ichthyosis linearis circumflexa, but regular treatment is likely necessary to maintain remission.

This article discusses the potential of phospholipase A2 inhibition as a therapeutic strategy for inflammatory skin diseases and emphasizes the need for further exploration of its role and administration methods.

This study suggests that the expression and localization of toll-like receptors and caveolin-1 in lichen planopilaris may influence cicatricial alopecia pathobiology and that downregulating caveolae could offer a novel management strategy.

This study found that the peptide derivative beta-Ala-Pro-Dab-NHbenzyl may reduce wrinkles and sebum production in human skin by inhibiting dipeptidyl peptidase 4, suggesting potential for acne and skin inflammation treatment.

This study reported dramatic improvements in five collodion baby patients with lamellar ichthyosis treated with oral retinoic acid, noting hair loss as the sole adverse effect, emphasizing the treatment's promising efficacy for physicians.

This study demonstrated that Reverse Protein Engineering can decrease the size of Firefly Luciferase from 550 to less than 80 amino acids, but further research is needed to ensure these smaller peptides retain bioluminescent activity.

This study suggests that inhibiting PKC, similar to rapamycin treatment, can extend lifespan and reduce neurological symptoms and inflammation in mice with mitochondrial dysfunction, potentially involving the mTORC2 pathway.

Specific cross-linkages help make hair proteins stable and strong.

This case report describes a 47-year-old man with a persistent erythematous scaly plaque on his left lower eyelid, unresponsive to conservative treatment, later diagnosed through biopsy.
