Saffron for the Management of Premenstrual Dysphoric Disorder: A Randomized Controlled Trial.

Background: Selective serotonin reuptake inhibitors are among the most common agents have been used for the treatment of the premenstrual dysphoric disorder (PMDD); however, due to the diversity in the outcomes and adverse effects, efforts are in progress to find an agent with maximal efficacy and minimal adverse effects. Saffron is an herbal agent consisted of ingredients shown to act as an antidepressant, pain tranquilizer, and antioxidant. In the current study, it is aimed to assess the efficacy of saffron on PMDD treatment.

One-pot facile simultaneous synthesis of conductive Ag-polyaniline composites using Keggin and Preyssler-type phosphotungstates.

Two heteropolytungstate structures, Keggin (HPWO) and Preyssler (H[NaPWO]), were used to synthesize conductive silver nanoparticle-polyaniline-heteropolytungstate (AgNPs-PAni-HPW) nanocomposites. During the oxidative polymerization of aniline, heteropolyblue was generated and served as the reducing agent to stabilize and distribute AgNPs within "PAni-Keggin" and "PAni-Preyssler" matrixes as well as on their surfaces. The prepared nanocomposites and AgNPs were characterized using UV-visible (UV-Vis) and Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), pore size distribution BET, scanning electron microscopy (SEM), and transmission electron microscopy (TEM).
