Clinical effectiveness of efinaconazole 10% solution for treatment of onychomycosis with longitudinal spikes.

Onychomycosis with longitudinal spikes in the nail plate has been reported to be refractory to oral drugs as with dermatophytoma. We evaluated the efficacy of 10% efinaconazole solution in the treatment of onychomycosis with longitudinal spikes. Of the 223 subjects who were enrolled in a previous study, a post-hoc analysis of 82 subjects with longitudinal spikes was performed in this study.

Efficacy of long-term treatment with efinaconazole 10% solution in patients with onychomycosis, including severe cases: A multicenter, single-arm study.

We evaluated the efficacy of efinaconazole 10% topical solution in long-term use, for up to 72 weeks, for onychomycosis, including severe cases. Among 605 participants, 219 patients diagnosed as having onychomycosis were evaluated for the efficacy of efinaconazole. The treatment success rate (<10% clinical involvement of the target toenail) at the final assessment time point was 56.

Differentiation induction of human keratinocytes by phosphatidylethanolamine-binding protein.

Phosphatidylethanolamine-binding protein (PEBP) has been demonstrated to bind to Raf-1 and mitogen-activated protein kinase kinase, components of the extracellular signal-regulated protein kinase (ERK) pathway, thereby inhibiting the pathway and resulting in the suppression of cell proliferation. In the present study, we examined whether PEBP is involved in differentiation induction of human keratinocytes. PEBP expression was immunohistochemically examined in normal human skin and skin cancers with different differentiation properties.

Polymorphic glutathione S-transferase subunit 3 of rat liver exhibits different susceptibilities to carbon tetrachloride: differences in their interactions with heat-shock protein 90.

Rat glutathione S-transferase (GST) subunit 3 gene has polymorphism, one type encoding Asn(198)-Cys(199) (NC type) and another encoding Lys(198)-Ser(199) (KS type). To examine whether the two types of GST 3-3 exhibit different susceptibilities to oxidative stress in vivo, rats were administered with CCl(4), a hepatotoxin causing severe oxidative stress, and its effect on liver GST 3-3 was compared. Decrease in GST activities in liver due to CCl(4) administration was more evident in NC type rats than in KS type rats, and most GST activities of KS type rats were confined to S-hexylglutathione-Sepharose, whereas those of NC type rats were not.
