The in vitro drug release, permeation, pharmacokinetic, biochemical, and pharmacodynamic experiments were done to assess the improvement in in vivo fate and efficacy of RIZ.Results The size of optimized RIZ CSNPs was found to be 173.6 ± 2.23 nm and polydispersity index (PDI) of 0.264 ± 0.002 while that of RIZ-Tf CSNPs was 207 ± 2.49 nm and 0.406 ± 0.002. In vitro release was found to be 86.15 ± 7.316% and 91.1 ± 5.836%, respectively, while permeability coefficient was found to be 4 × 10-2 and 4.2 × 10-2 cm/s for RIZ CSNPs and RIZ-Tf CSNPs. The biochemical analysis studies revealed that oxidative stress was significantly decreased in case of RIZ CSNPs and RIZ-Tf CSNPs (p  less then  0.01) treated groups. The antianxiety effect and the memory restoration were evident in pharmacodynamic studies (p  less then  0.05) of the prepared formulations.Conclusion The results of pharmacokinetic studies demonstrated the remarkable brain delivery of RIZ-Tf CSNPs through intranasal route as compared to the RIZ solution.Aim We aimed to identify metabolic characteristics of early-stage heart failure (HF) and related biomarkers. Patients & methods One hundred and forty-three patients with New York Heart Association class I-IV HF and 34 healthy controls were recruited. Serum metabolic characteristics of class I HF were analyzed and compared with those of class II-IV HF. Potential biomarkers of class I HF with normal N-terminal-pro-B-type natriuretic peptide (NT-proBNP) level were screened and validated in additional 72 subjects (46
