The covid-19 coronavirus has killed more than 5,129,829 people, globally, out of about 255,098,687 infected. About 10 million persons died from cancer in 2020, with 19.3 new cases diagnosed. About 409,000 persons died of malaria in 2019. And none of these diseases made the WHO's list of top 5 deadly diseases of 2019. Modern medicine has made tremendous progress in the prevention and treatment of disease, but the crashing of the covid-19 coronavirus and the extremely high burden of the top deadly diseases point to the urgency of radical and totally disrupting inventions in medicine. Indeed, to effectively overcome the current burden of deadly diseases we need an agile platform with exponentially better efficacy and predictability. The world is in dire need of a new medicine platform that totally and radically disrupts the current healthcare systems and the traditional ways of preventing and treating disease. The present invention does that. The present invention uses transformed microbes, targeted to one or more mucosal surface, to prevent and treat just about any disease of importance. The current means of disease prevention relies on vaccines. As we have seen from countless failures and booster shots, vaccines have extreme limitations and increasingly fewer following.

The planetary outbreak of COVID-19 has led to a substantial death toll and has hindered the functioning of modern society. This underlines the importance of accurate, cost-effective serological antibody tests and point-of-care diagnostics to monitor the viral spread and to contain pandemics and endemics. This requires a cost-effective three-dimensional nanofluidic device for rapid and multiplexed detection of viral antibodies. The device is configured to size-dependently immobilize particles at predefined positions from a multiparticle mixture, giving rise to distinct trapping lines. It is shown with the device that distinctive lines can be used as an on-chip and on-bead fluorescent linked immunosorbent assay for the detection of immunoglobulin G (IgG) antibodies against the receptor-binding domain of SARS-CoV-2 in human serum. Device versatility is exhibited by on-bead color multiplexing for simultaneous detection of IgG and IgM in convalescent human serum and by concurrent detection of anti-spike (SARS-CoV-2) and anti-hemagglutinin (Influenza A) antibodies.

Resumen de: US2024124917A1
Rapid, sensitive, and specific point-of-care testing for pathogens is crucial for disease control. Lateral flow assays (LFAs) have been employed for nucleic acid detection, but they have limited sensitivity and specificity. A fusion of catalytically inactive Cas9 endonuclease and a relaxase for example, VirD2 are used for sensitive, specific nucleic acid detection by LFA. VirD2-dCas9 specifically binds the target nucleic acid sequence via dCas9 and covalently binds to a FAM-tagged oligonucleotide via VirD2. The biotin label and FAM tag are detected using a LFA. This system, termed Vigilant (VirD2-dCas9 guided and LFA-coupled nucleic acid test) is coupled to reverse transcription-recombinase polymerase amplification to detect pathogenic nucleic acid of interest in a sample, it exhibits an impressive limit of detection and shows no cross-reactivity, thus reducing incidents of false positives. Vigilant offers an easy-to-use, rapid, cost-effective, and robust detection platform for SARS-CoV2.

Due to the precautions put in place during the COVID-19 pandemic, utilization of telemedicine has increased quickly for patient care and clinical trials. Unfortunately, teleconsultation is closer to a video conference than a medical consultation with the current solutions setting the patient and doctor into a discussion that relies entirely on a two-dimensional view of each other. A telehealth platform is augmented by a digital twin of the patient that assists with diagnostic testing of ocular manifestations of myasthenia gravis. A hybrid algorithm combines deep learning with computer vision to give quantitative metrics of ptosis and ocular muscle fatigue leading to eyelid droop and diplopia. The system works both on a fixed image and video in real time allowing capture of the dynamic muscular weakness during the examination. The robustness of the system can be more important that the accuracy obtained in controlled conditions, so that the system and method can operate in practical standard telehealth conditions. The approach is general and can be applied to many disorders of ocular motility and ptosis.

Disclosed in the present invention are an SARS-COV-2 antigen polypeptide, a recombinant adeno-associated virus and the use thereof. The present invention uses an S protein or RBD of the SARS-COV-2 antigen polypeptide as an antigen. A truncated domain has a shorter sequence length, a smaller molecular weight and a clearer structure, and has specificity. The recombinant adeno-associated virus, which contains a nucleic acid sequence encoding the antigen polypeptide achieves gene delivery via intramuscular injection and can effectively and continuously express the antigen polypeptide. The antigen polypeptide, which is expressed by the recombinant adeno-associated virus of the present invention in vivo, can induce a specific immune response against the SARS-COV-2 antigen polypeptide, and an antibody serum produced thereby can not only specifically recognize the SARS-COV-2 RBD antigen polypeptide, but also has a neutralizing titer, and can inhibit the replication and transmission of variant strains Delta and Omicron or prevent the variant strains Delta and Omicron from settling in a host, thereby effectively preventing and/or treating COVID-19 caused by SARS-CoV-2.

A method for detecting novel coronavirus on the basis of receptor binding. The method comprises: using cross-linked agarose as a matrix, and performing surface modification with carboxyl on same to then obtain magnetic agarose microspheres; binding the magnetic agarose microspheres to a receptor protein by means of covalent coupling to form receptor-protein-coupled magnetic agarose microspheres, wherein the receptor protein covalently bound to the surfaces of the magnetic agarose microspheres recognizes the receptor binding region of the outer-membrane S protein in a novel coronavirus sample, allowing the two to bind to each other to simulate the binding process of novel coronavirus and a host cell so as to capture novel coronavirus; sequentially cleaning, purifying and eluting the magnetic microspheres to obtain novel coronavirus having the ability of binding to cells; and detecting and evaluating the infection activity and transmissibility thereof by means of combined immunobinding-fluorescence quantitative PCR. The method is suitable for evaluating viral replication and transmission during the treatment of a person infected with novel coronavirus, and the infectivity of novel coronavirus in a cured patient when he/she experiences novel coronavirus rebound.
