This study suggests that increased activity of the histamine synthesizing enzyme histidine decarboxylase may play a role in initiating the anagen phase of hair regrowth in mice.

This study reports that 2-(1-Adamantyl)-4H-thiochromen-4-on-6-O-sulfamate is the most potent steroid sulfatase inhibitor identified so far, exhibiting 170-fold higher activity than the lead compound estrone sulfamate.

This study found that the cosmetic olfactory receptor agonist cyclohexyl salicylate may stimulate hair growth and expand stem cell progeny, suggesting potential as a cosmetic adjuvant for hair loss.

This study found that adding rose hip extract to permanent wave solutions increased wave effectiveness and reduced hair damage, although variations in hair type may affect the results.

This study found that Hairless (HR) and putrescine form a negative regulatory network that impacts epidermal homeostasis and hair follicle cycling, linked to the MYC superfamily's regulation of ODC expression.

This study found that spinal strychnine enhances low threshold tactile responses in cat dorsal horn neurons, which may mirror pain states in humans that are less responsive to opioid treatments.

This study found that compound 2g inhibits steroid sulfatase effectively without exhibiting estrogenic activity, making it a promising candidate for breast cancer treatment.

New mutations in hair keratin genes cause the rare hair disorder monilethrix.

This study found that trametinib and vemurafenib increased sebum production and gene expression related to lipid accumulation in hamster sebocytes, which may help explain certain side effects in patients.

This case report highlights a rare instance of fingernail and toenail hyperpigmentation following the use of valproic acid, which resolved after discontinuation of the drug.

This study found that stimulating the olfactory receptor OR2A4/7 with cyclohexyl salicylate promoted human hair growth and increased progeny of hair follicle epithelial stem cells in an ex vivo setting.

This study found that Naringenin and Hesperetin significantly increased the proliferation of hair-related cells and suggested potential as natural hair growth-promoting agents.

This review discusses transdermal drug delivery using hydrogel-forming microneedles and highlights their potential and challenges for clinical application, but it reports no new clinical findings.

This case report observed vemurafenib-induced pityriasis amiantacea, a scalp scaling reaction, in a patient with metastatic melanoma, which was managed symptomatically without altering vemurafenib treatment.

This study used LC-HRMS to detect undeclared pharmaceutical ingredients like minoxidil and finasteride in hair serums, finding risk to public health due to their toxicological properties and advocating for manufacturer transparency.

In this case study, electron microscopy revealed that harlequin ichthyosis involves giant mitochondria in keratinocytes and abnormal lamellar granule development, which may contribute to pathogenesis through altered lipid metabolism.

In this retrospective study, all-female patients with iron deficiency anemia treated with ferric carboxymaltose experienced rapid symptom resolution and increased ferritine and hemoglobin levels, with some reporting manageable side effects such as rash and headache.

This study found that concentrations of haloperidol and its metabolite in human scalp hair significantly correlated with the daily dose and plasma trough levels in patients taking haloperidol.

Certain enzymes react strongly with some hormones in rat skin during hair growth, mainly in sebaceous glands and hair sheaths.

This paper reviews adverse events related to hedgehog pathway inhibitors in advanced basal cell carcinoma patients, reporting no new clinical results but aiming to inform healthcare professionals for improved patient care.

This study concluded that mixtures of weak endocrine disruptors, such as parabens and azole fungicides, can produce combination effects that should be considered in regulatory risk assessments to avoid underestimating potential risks.

This study used NMR spectroscopy and other techniques to fully assign the proton and 13C spectra of the 5α-reductase inhibitor finasteride.

This review discusses the development and potential therapeutic applications of adenosine receptor agonists and positive allosteric modulators, noting that while many clinical trials have been unsuccessful, initial results for new compounds are promising.

This review discusses the biologically active compounds in Maxillariinae orchids, highlighting 62 semiochemicals with medical potential, but reports no new clinical findings.

This review outlines the development and clinical use of three generations of antihistamines, noting that while first-generation drugs have multiple side effects including sedation, second- and third-generation antihistamines offer greater efficacy and safety due to their selective action on peripheral H1 receptors.

This study found that chronic use of Russelia equisetiformis extracts in rats may impair liver function, with a more pronounced effect observed from the methanol extract.

This review discusses the antimicrobial and protective effects of hesperidin and hesperetin against various toxicities, with potential mechanisms explored, but it reports no new research findings.

This report describes two cases of chronic arsenicism, one involving criminal poisoning by a sibling and the other associated with prolonged use of Fowler's solution.

This article discusses the introduction of human recombinant hyaluronidase in hair restoration surgery and presents no new clinical results.
