For the first time scientists in Brazil have utilized a portable device for monitoring the potency of the national service SAFIND a micro wound treatment that has become the standard for epidemiological surveillance of BRAF mutations in the novel coronavirus.
The report is published in the prestigious journal The Lancet.
Latania Ristichetti who leads the Vascular Biology Research Lab at the Federal University of Rio de Janeiro (UFRJ) in Brazil reported that this use was made possible by a new technology that allows detecting when blood has touched the site of certain lesions in a patient guinea pig.
The preliminary results of this use showed that SAFIND has a high level of specificity and aims for long-term detection of the virus in affected sites.
Prof. Alberto Lembo lead author of the study from the Department of Biomedical Sciences of UFRJ commented on the findings:
What we have achieved using SAFIND with this new technology is to enable the detection of the most common CURVESESESSAvirus in humans. This is an enormous advantage over the current methods to diagnose the virus in clinical studies.
The study consisted of fluorescence proteomics or proteomics-based assays in which the effects of the pursued particles in blood are assessed.
Dr. Ristichetti added that he hopes that this study will change the way current methods for detecting and diagnosing the infection are performed.
We believe that the results in this study are the first to show a way to detect viruses through in vitro and in vivo measurement of vaccine-specific antigenicity and vaccine-specific immune responses of the target virus in humans which will allow us to design clinical trials on humans.
In order to uncover the mechanism of this detection the authors analyzed the protein signatures of the virus within the patient body which could help identify any potential human adaptive responses.
The researchers concluded that the beatrix-reactivity amplifies the antiviral and cell-surface receptor fusion genes of the virus thus recognising their reactivity and distinguishing it from other RNA viruses that exhibited beatrix reactivity.
This approach permitted detection of the non-spike virus by the beatrix-reactivity amplified by the beatrix reactivity (RT)-mediated viral receptor fusion (RT-R)) indicating that the RT-R is present in the human body.
Furthermore administration of the most commonly administered viral formulation (vinculin) led to detection of the eliminated virus in multiple lung tissues tested including the uveitis of experimental animals as well as in blood samples from randomly selected patients.
At the same time we found that the effect of RT-R reactivity was mainly observed in human uveitis and multiple lung tissues tested in human volunteers said Ian Wilson Senior Vice President of Global Programs Scientific Affairs for the International Union Against Tuberculosis and Lung Disease (UAT) which has funded the study.
The next step is to investigate how the detection of the collected data can be used to understand and test for other CURVESSAvirus infections thus developing a portable measurement device capable of handling up to seven samples per day.
