چکیده
A diluted 3% w/w hydrogen peroxide solution acidified to pH 2.5 by adding citric acid inactivated SARS-CoV-2 virus more than 4 orders of magnitude in 5 min. After a contact time 15 min, no viral replication was detected. Aqueous solutions sodium percarbonate coronavirus >3 log10 diminution Conversely, H2O2 with additives displayed scarce virucidal activity (1.1 min), confirming that pH-modifying ingredient is necessary have H2O2-based disinfectant active against the novel coronavirus.

Aqueous-phase oxidation of alcohols with green oxidants (Oxone and hydrogen peroxide) in the presence of MgFe2O4 magnetic nanoparticles as an efficient and reusable catalyst
Nanomagnetic MgFe2O4 is an active, stable, and reusable catalyst for the oxidation of alcohols. The oxidation of various primary and secondary alcohols has been examined and related corresponding products were obtained in good yields. The reactions were carried out in the presence of water as solvent and oxone (at room temperature) or H2O2 (at 60 ºC) as an oxidant. The catalyst was investigated...
متن کاملSARS-COV-2 Virus; Immune Responses and The Immunopathogenesis
Abstract Background and Objectives Clinical features of SARS-COV-2 virus include fever, headache, cough, sore throat, and shortness of breath, and in severe forms it leads to disseminated intravascular coagulation, septic shock, and ultimately death. Excessive secretion of proinflammatory cytokines such as TNF-α, IL-6, and IL-1 leads to cytokine storms in this disease. The emergence of new va...
متن کاملStability of SARS-CoV-2 in Different Environments and the Effect of Disinfectants on its Survival
In December 2019, the prevalence of a pneumonia with unknown cause was reported in China which was later named Coronavirus Disease 2019 (COVID-19) caused by a virus called SARS-CoV-2. One of the most important ways of COVID-19 transmission is contaminated surfaces. In this review study, we investigated the stability of SARS-CoV-2 in air and on surfaces and the methods of preventing its spread R...
متن کاملSARS-CoV-2 infection: its psychiatric manifestations
Background: The clinical presentation of SARS-CoV-2 infection was initially dominated by respiratory symptoms. However the clinical spectrum is wide and neuropsychiatric syndromes are also a source of medical concern. Our aims are to present an atypical clinical presentation of SARS-CoV-2 infection characterized by auditory hallucinations and unusual behavior and to emphasize the diversity of ...
