International eDelphi Study to Reach Consensus on the Methotrexate Dosing Regimen in Patients With Psoriasis.

Importance: A clear dosing regimen for methotrexate in psoriasis is lacking, and this might lead to a suboptimal treatment. Because methotrexate is affordable and globally available, a uniform dosing regimen could potentially optimize the treatment of patients with psoriasis worldwide.

Objective: To reach international consensus among psoriasis experts on a uniform dosing regimen for treatment with methotrexate in adult and pediatric patients with psoriasis and identify potential future research topics.

Diet influences the intake target and mitochondrial functions of Drosophila melanogaster males.

In this study, we examine the dietary protein to carbohydrate ratio (P:C) on the mitochondrial functions of two Drosophila melanogaster mtDNA haplotypes. We investigated multiple physiological parameters on flies fed with either 1:12 P:C or 1:3 P:C diets. Our results provide experimental evidence that a specific haplotype has a reduction of complex I activity when the flies are fed with the 1:12 P:C diet.
