This invention discloses an in vitro maturation culture medium for ferret oocytes and its preparation method, belonging to the field of animal embryo engineering technology. It comprises the following components: TCM199 basal culture medium, 50 mL fetal bovine serum, 25 IU follicle-stimulating hormone, 25 IU luteinizing hormone, 0.5 mg 17β-estradiol, 0.005 mg epidermal growth factor, 12.1 mg sodium pyruvate, 0.2 mM cysteine, 0.1 mM cysteine, 0.030 g penicillin, 0.025 g streptomycin sulfate, as well as an antioxidant complex, a combination of growth factors, and extracellular matrix components. This invention provides a comprehensive and suitable nutritional environment for ferret oocytes by precisely formulating a composite culture medium containing multiple key components. Specifically, the hormone combination at specific concentrations accurately simulates the in vivo physiological environment, effectively regulating the oocyte maturation process; multiple growth factors work synergistically to promote oocyte growth, development, and differentiation; and the addition of the antioxidant complex effectively eliminates free radicals generated during in vitro culture, reducing oxidative stress damage to oocytes.

This invention discloses a recombinant 2-O-sulfonyltransferase mutant and its preparation method, belonging to the field of biotechnology. The recombinant enzyme sequence is formed by fusing a truncated (E28~N356) mutant of hamster-derived 2-O-sulfonyltransferase (L119V-R188E-A240I) with an N-terminal maltose-binding protein (MBP) tag. The recombinant 2-O-sulfonyltransferase mutant exhibits higher activity, 1.9 times that of the recombinant wild type, and greater stability, retaining 86.6% of its activity after 5 days at room temperature. Furthermore, the soluble expression level of this recombinant mutant 2-O-sulfonyltransferase is increased by 5 times. This mutant, as a novel biocatalyst with high efficiency, stability, and controllable production costs, has significant application value and broad industrialization prospects in the industrial enzymatic synthesis of glycosaminoglycans such as heparin and heparan sulfate.

A solution has been discovered that provides a more effective Coronavirus vaccine. The solution is an mRNA vaccine encoding a SARS-CoV-2 nucleoprotein (N) (mRNA-N) in combination with an mRNA vaccine encoding SARS-CoV-2 spike protein(S) (mRNA-S). Chemically modified mRNA-N (pseudouridine) and / or chemically modified mRNA-S (pseudouridine) can be synthesized and packaged in lipid nanoparticles (LNP). In mouse and hamster models, it was shown that mRNA-N alone is immunogenic and can significantly diminish viral loads in the mouse lung after prime-boost intramuscular immunization. In addition, the combinatorial mRNA-N / mRNA-S vaccination induces substantially stronger protection against SARS-CoV-2 than vaccination with mRNA-S alone.

The disclosures of the invention arc directed to the manufacture of effective, affordable vaccines that arc globally accessible. Using a platform conjugation technology, highly immunogenic conjugate vaccines were produced that elicit broad cross-neutralization to variants of concern (VOC), manufactured cheaply compared to mRNA vaccines. Protein-protein conjugates and Toll-Like Receptor (TLR) agonist adjuvants were shown to enhance immunogenicity and induce broad cross-protection against VOC, a characteristic lacking in early mRNA CO VID-19 vaccines. Murine nAb titers from Beta-only conjugates were equivalent between Beta, Delta, Omicron BA.l, BA.2, and BA.4 / BA.5, which were circulating up to three years after the antigenic strain. Additionally, Beta-Delta bivalent conjugate vaccines readily prevented disease in hamster challenge, which demonstrates a vaccine with remarkably broad cross-protection and potential to protect for extended periods despite mutations, without requiring expensive boosters or antigen adaption. This vaccine can be produced in our highly automated, large-scale manufacturing facility enabling economical production of inexpensive, effective vaccines for high-need areas.

The invention pertains to pet care products, specifically: litter box fillers for animals (cats, hamsters, rabbits, guinea pigs, terrariums, and others) living in human dwellings, and can also be used as bedding / flooring in chicken coops, horse stables, and livestock farms. The animal litter box filler is manufactured in granular form from recycled waste paper in the form of newspapers, books, corrugated cardboard, and natural additives. The raw material undergoes a series of steps: shredding, fluffing, and moistening to 15-25%, resulting in finished granules with a diameter of 4-12 mm and a length of 6-18 mm. The filler manufacturing process includes preliminary raw material sorting, subsequent shredding, fluffing, moistening, and then granulation and cooling of the granules. In the granulation machine, the raw material is pressed through round openings using a die die.The technical result consists of expanding the range of fillers and increasing the filler absorbency, as well as increasing the service life when stored in a dry place and convenient disposal into the sewer system or food waste for further processing.

The present invention provides protective monoclonal antibodies targeting Nipah virus (NiV) G protein and their uses, wherein the monoclonal antibodies can recognize Nipah virus G protein. The present invention uses NiV G protein as an antigen target, displays antigens on a ferritin nanoparticle platform to immunize mice, and screens out two monoclonal antibodies LN1F9 and LN1D11 that can specifically bind to NiV G protein. In vitro neutralization experiments have shown that these two antibodies have high neutralizing activity against both NiV-M and NiV-B strains, among which LN1F9 can also neutralize Hendra virus (HeV) of the same genus. The monoclonal antibodies LN1F9 and LN1D11 can effectively treat hamsters infected with NiV and prevent NiV infection in hamsters. They have extremely high application value in clinical treatment and prevention of NiV and HeV infection, and can be used to prepare detection products and preventive and therapeutic drugs for NiV and HeV.

Disclosed in the present invention are an anti-SARS-CoV-2 arylnaphthalene lignan compound, and a preparation method therefor and the use thereof. Results show that ANL-1, ANL-2, and ANL-4 to ANL-7 have no toxicity to Vero E6 cells, and ANL-3 has low toxicity to Vero E6 cells. In a Vero E6 cell model, the in vitro anti-SARS-CoV-2 activities of ANL-7 and ANL-2, in TI value, are respectively 19 times and 16 times that of remdesivir, and are higher than the in-vitro anti-SARS-CoV-2 activity of a market-available drug. ANL-2 has a significant inhibitory effect on RNA-dependent RdRp activity of SARS-CoV-2, and ANL-2 also effectively limits the replication of various pathogenic coronaviruses in Caco2 cells or hamsters. It can be seen that the arylnaphthalene lignan compound has a good anti-coronavirus activity and can be used for treating and preventing SARS-CoV-2 infection or delaying the progress of SARS-CoV-2 infection in a patient.
