  • Publication number: 20220396798
    Abstract: This invention relates to a novel mRNA composition and its production method useful for developing and manufacturing RNA-based anti-viral and/or anti-cancer vaccines and medicines. This invention includes two types of mRNA constructs, namely “5?-hairpin messenger RNA (5hmRNA)” and “messenger-hairpin-messenger RNA (mhmRNA)”, respectively. Both of 5hmRNA and mhmRNA contain at least a hairpin-like stem-loop RNA structure. The 5hmRNA contains at least a stem-loop RNA structure in the 5?-UTR of a protein/peptide-coding mRNA, while the mhmRNA contains a middle stem-loop structure flanked with two protein/peptide-coding mRNA sequences on both sides. In mhmRNA, the first 5?-mRNA preferably encodes an RNA replicase, for amplifying the second 3?-mRNA in transfected cells. After transfection into target cells, 5hmRNA and mhmRNA can be further translated into at least a desired protein/peptide.

  • Patent number: 11446654
    Abstract: A substrate structured to define thereon a fluid flow channel and/or a fluid control feature is described. The substrate may additionally comprise a capture zone and/or a test zone, for use as a test strip for determining presence or absence of an analyte of interest, such as an infectious agent or a biomarker. Reagents are deposited in the capture zone and/or test zone as an array of drops.

  • Patent number: 11326164
    Abstract: This invention generally relates to a group of novel chemical compositions and their use for formulating RNA- and/or DNA-based medicine drugs/vaccines into stable compound complexes useful for both in-vitro and in-vivo delivery. Particularly, the present invention teaches the synthesis of a group of novel trimethylglycyl chemicals and their use for formulating cosmetic, therapeutic- and/or pharmaceutical-grade nucleic acid compositions, including but not limited microRNA precursors (pre-miRNA/miRNA), small hairpin RNAs (shRNA), short interfering RNAs (siRNA), ribozymes, antisense oligonucleotides, RNA-DNA hybrids and DNA-based vectors/vaccines, with or without modification, into delivery complexes, which can then be absorbed by cells in vivo, ex vivo and/or in vitro through an active mechanism of endocytosis via acetylcoline receptors for releasing the therapeutic and pharmaceutical effects of the formulated nucleic acid compositions.

  • Publication number: 20210255178
    Abstract: Immunoassay devices with plurality of fluid flow channels that are discrete and designed for optimal fluid control are described. Substrates configured to control the rate of fluid flow for in-situ immunoassay measurements to detect and quantify the presence of one or more analytes of interest in a sample are also described. More specifically, the present disclosure relates to consumables for lateral flow assays, which in conjunction with an instrument detect markers or causative agents of medical conditions.

  • Publication number: 20210215715
    Abstract: Methods and kits for diagnosis of confirmatory diagnosis of a tick-borne infection, such as Lyme disease, is provided. The methods and kits include one or more multi-channel lateral flow immunoassay test strips. In an embodiment, the test strip comprises at least five individual, discrete fluid flow channels where each of the at least five channels includes one or more binding members (antigens) for detection of immunoglobulin antibodies against a Borrelia bacterium in a blood sample. The binding members (antigens) are, in one embodiment, selected from a group of immunoglobulin antibodies consisting of p18 (decorin-binding protein), p23, p28, p30, p39, p41 (flagellin), p45, p58, p66, p93, VlSE/C6 and p31. The kits include external controls selected from a container with a positive control, a container with a negative control, and both of a container with a positive control and a container with a negative control.

  • Patent number: 9956196
    Abstract: This invention is related to a novel sugar-like chemical composition and its use for diabetes therapy. Particularly, the present invention teaches the use of monosaccharide-like glycylated sugar alcohol compounds to block or reduce sugar absorption in diabetes patients, so as to prevent the risk of hyperglycemia symptoms. Glycylation of sugar alcohols is a totally novel reaction that has never been reported before. Therefore, the novelty of the present invention is that for the first time glycylated sugar alcohols not only was found but also was found to be useful for treating Diabetes mellitus. In addition, the present invention teaches a method for producing these glycylated sugar alcohols. In sum, the present invention includes not only a kind of novel sugar-like chemical compositions and its use for treating diabetes but also a state-of-the-art protocol and methodology for producing such a novel composition via glycylation of sugars and sugar alcohols.
