Background Omega-3 may alleviate the severity of coronavirus disease 2019 (COVID-19) by reducing the C-reactive protein (CRP) level, a marker for systemic inflammation. Because the scientific evidence indicating such a role is inconsistent, we aimed to evaluate the effect of Omega-3 on CRP change and CRP level in patients with COVID-19. Methods We conducted a comprehensive search on four databases (PubMed, Web of Science, EMBASE, and Scopus). We included all RCTs comparing Omega-3 with a control group regarding their effect on the CRP levels in patients with COVID-19. We used version two of the Cochrane risk of bias assessment tool to appraise the included studies. We extracted data to an online data extraction sheet. The primary outcomes were CRP change from baseline and CRP serum levels. Results We included four randomized controlled trials (RCTs) with 274 patients in this study. The overall effect estimate favored Omega-3 over the control group in terms of CRP change from baseline (mean difference (MD) =− 2.53, 95% confidence interval (CI): − 4.40, − 0.66) and CRP serum levels at the end of the study (MD =− 6.24, 95% CI: − 11.93, − 0.54). Conclusion Omega-3 showed promising effects on systemic inflammation by reducing CRP levels in COVID-19 patients. Based on this finding, we recommend Omega-3 for COVID-19 patients for its anti-inflammatory actions.
Mononuclear chelates of Cr(III), Mn(II), Fe(III), Ni(II), Cu(II), Zn(II) and Cd(II) resulting from new tridentate Schiff base ligand, 4-((1-(5-acetyl-2,4-dihydroxyphenyl)ethylidene)amino)-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one, were synthesized and characterized via various spectroscopic methods. Metal to ligand ratio was found to be 1:1, which was revealed via elemental analysis. IR has sharp out that the coordination of the ligand towards the metal ions was carried out via NOO atoms. UV-Vis, 1HNMR spectral data, molar conductance measurements, BET surface area, melting points and theoretically through density function theory were used such as characterizing techniques in supporting of further interpretation of the complexes structures. The complexes were octahedral except Cu(II) and Ni(II) complexes were tetrahedral as suggested through the magnetic moment measurement. The complexes were found to have surface area, pore volume and particle radius 23–176 m2 g− 1, 0.02–0.33 cc/g and 8.71–4.32 nm, respectively, as pointed out from BET measurement. Schiff base ligand and its metal complexes were tested in vitro to estimate their bactericidal activity opposed to Gram-negative and Gram-positive bacteria and antifungal organisms. In the recent incident of a novel coronavirus (SARS-CoV-2) spreads, antiviral drug detection is of most importance. MOE 2008 was used headed for screen potential drugs with molecular docking by the structural protein and non-structural protein sites of new coronavirus and the study was constructed to molecular docking without validation through MD simulations. Interactions with the main protease may play a key role in fighting against viruses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
