Highly sensitive spectrofluorimetric methods were developed for the quantitative estimation of formoterol fumarate dihydrate (FFD) and fluticasone propionate (FP) in both authentic raw materials and marketed dosage forms using a micellar-enhanced spectrofluorimetric approach. The proposed methods are based on the determination of FP in the presence of FFD using the first derivative emission spectrofluorimetry. The peak amplitude of the emission spectra of the formed micellar fluorescence was measured at 465 nm after excitation at 236 nm (λ max of FP).

Introduction: Exercise is a simple, safe, and affordable solution that can be easily taught to men with chronic illnesses to improve their psychological burden and sexual health.
Aim: Since the role of exercise in ameliorating the psychological burden associated with erectile dysfunction (ED) in hepatitis C (HC) men was not explored, this research aimed to explore this role.
Material And Methods: This HC study was a randomized-controlled exercise-rehabilitation trial.
Background: Tissue damage by viral hepatitis is a major cause of morbidity and mortality worldwide. Oxidation reactions and reactive oxygen species (ROS) transform proteins and lipids in plasma low-density lipoproteins (LDL) into the abnormal oxidized LDL (ox-LDL). Hepatitis C virus (HCV) infection induces oxidative/nitrosative stress from multiple sources, including the inducible nitric oxide synthase (iNOS), the mitochondrial electron transport chain, hepatocyte NAD(P)H oxidases (NOX enzymes), and inflammation.

Three models were developed and compared: partial least squares (PLS), artificial neural networks (ANN), and multivariate curve resolution-alternating least squares (MCR-ALS) where the four studied drugs were successfully quantified. The quantitative determination of the studied drugs was assessed using percentage recoveries, standard errors of prediction, and root mean square errors of prediction.

Chemical structures of all isolated compounds were established depending upon the spectroscopic data including, 1D and 2D NMR and HRMS. Colo-205 (colorectal cancer), HepG2 (hepatocellular carcinoma) and MCF-7 (breast adenocarcinoma) and cancer cell lines were used to test the cytotoxic potential of the isolated compounds (-).
