“…An explanation not offered by the authors is that high concentrations of air ions caused the aerosolized virus to be removed from the air, thus reducing exposure of the animals to the virus and mortality. It is well known that high concentrations of air ions can reduce levels of viruses, aerosols, and particles in confined spaces [ 104 , 105 ]. Overall, exposure to higher levels of air ions did not produce greater mortality from respiratory infections than lower density exposures (Fig.…”

Exposure of laboratory animals to small air ions: a systematic review of biological and behavioral studies

BackgroundAir ions are molecules of air that have become ionized—that is, they have either lost or gained an electrical charge. Past speculation has suggested that exposure to positive air ions may be harmful to one’s health, while exposure to negative air ions may be associated with beneficial health effects. Air ions arise from natural sources as well as direct-current transmission lines and commercial ionizers. Several recent clinical studies have suggested therapeutic effects of air ions on various types of depression at exposure levels 10- to 1000-fold higher than most previous human studies. The aim of this study was to assess the evidence from studies of laboratory animals for beneficial or adverse effects of air ions on health.MethodsSixty-two studies (1935–2015) in nine topics areas were evaluated for quality and potential systematic bias by ARRIVE guidelines. Standardized mean differences or proportional differences between exposed and control groups were computed for 44 studies to quantitatively assess the strength of the evidence for exposure-related effects.ResultsMany of the studies were conducted before 1990 and exhibited various reporting and methodological deficiencies, including small sample size, failure to control for the influence of potential confounding variables, lack of randomized assignment to treatment groups and blinded analyses, and statistical errors relating to treating group-exposed animals as individuals. The highest quality studies consistently reported no effects of exposure on any of the endpoints examined. There were no evident dose–response relationships within or across studies.ConclusionsExperimental studies of laboratory animals exposed to positive and negative air ions for minutes to years over a five-log unit range of intensities did not suggest any consistent or reliable effects on measures of behavior, learning and memory, neurotransmitters, tracheal function, respiratory infection, cardiovascular function, reproduction and growth, carcinogenesis, or other health endpoints. These data do not provide evidence of adverse or beneficial effects of air ion exposure on health, and did not suggest any biological mechanism of interaction, except perhaps for mechanosensory stimulation of body surfaces by static electric fields at high air ion concentrations.Electronic supplementary materialThe online version of this article (10.1186/s12938-018-0499-z) contains supplementary material, which is available to authorized users.

“…This process involves also the generation of an air current transporting particles through the ionizing device (Wang, 2001). Ionization has been found effective to reduce airborne transmission of influenza A virus in poultry farms (Hagbom et al ., 2015). Another study investigated the inactivation of MS2 Coliphage through air ions generated by electrical discharge.…”

The COVID-19 pandemic is not only a challenge for public health and hospitals, but affects many aspects of our societies. This Lilliput minireview deals with problems that the pandemic causes for the food industry, addressing the presence and persistence of SARS-CoV-2 in the food environment, methods of virus inactivation and the protection of the food worker and the consumer. So far food has not been implicated in the transmission of the infection, but social disruptions caused by the pandemic could cause problems with food security.

“…This study was being support system and conducted to help and support the victim of Covid-19 [1] after the victim volunteered herself by signing the concept to take up the study as she is a final semester medical student and student of Prof.Ather from china. As integrative approach of non-invasive (ion therapy) [8] and non-drug therapy (diet, phytomedicines-18 herbs oral consumption, inhalators and application of nasal and chest) [9] , the modus or line of treatment was a follows;…”

Background:Covid-19 is a new born sibling of the influenza family of SARS-CoV-2, named on February 11, as a new type of corona virus by the WHO. Covid-19 indicates its close relationship with activity and approaches with the SARS virus, which further triggered as epidemic in 2003 and 2004 and now similar lung triggered by SARS-CoV-2 is called Covid-19 (Corona Virus Disease 2019). Methods: A combination of integrative therapies were administered to a 27 year old female positive with unknown SARS-CoV identified as COVID-19 with a query of coronavirus contaminated from travel history and a student of Wuhan with a respiratory congestion, integrative approach of non-invasive (ion therapy) and non-drug therapy, quantitative analysis by real time PCR, vital signs were recorded beforeand after the treatment, as all the vitals were normal and real time PCR results were monitored. Results: The integrative therapy with isolation for 29 days from 31 st January to 27 th February was found to be satisfactory and the report, which has Real time PCR values detecting Covid-19 positive on 29 th January 2020 gave a negative result,it showed not detected and less than 35 Ct for the test. Conclusion: The integrative approach showed that it has high potential in treatment of Covid-19and can further imbibed in republic of china as well as other places where in 136 volunteers are part of the study and this could be an adjuvant therapy with a integrative approach for Covid-19 treatments.
