Baimaside
Based on 5 publication(s) in Google Scholar
Baimaside (Quercetin 3-O-sophoroside) is a flavonoid cholinergic function modulator that binds to SARS-CoV-2-related targets. Baimaside regulates the expression of cholinergic system-related proteins and acetylcholine levels, improves scopolamine-induced learning and memory impairment, protects hippocampal neurons, inhibits pollen protein fluorescence, and protects pollen DNA. Its biosynthesis is regulated by multiple enzymes. Baimaside is completely absorbed in rats, undergoes phase Ⅱ metabolism and gut microbiota decomposition, and inhibits the invasion and proliferation of SARS-CoV-2 and its variants, making it suitable for research related to Alzheimer's disease and COVID-19.

RNA extraction experimental
By lysing cells, releasing RNA, and removing impurities such as proteins and DNA, high-purity RNA products are finally obtained. The commonly used traditional method is the guanidine isothiocyanate/phenol/chloroform method (Trizol), which is suitable for a variety of animal materials including animal tissues, microorganisms, cultured cells, etc., and most plant materials.

Protocol for Shuttle Box Test (TDPA)
The Shuttle Box Test for TDPA, or temporally dissociated passive avoidance, measures hippocampus-dependent associative learning by testing whether a rodent avoids entering a dark compartment that was previously paired with foot shock after a temporal delay between dark-compartment entry and shock delivery. The main behavioral readout is crossover or step-through latency from the light chamber into the dark chamber; increased latency across training or retention trials reflects learned avoidance memory rather than motor performance alone.
-
Protocol for Water Maze
The Morris Water Maze is a rodent spatial learning and memory assay in which a mouse or rat swims in opaque water to find an escape platform; in the hidden-platform version, the animal cannot see the platform and must use distal extra-maze cues to learn its fixed spatial location. The assay primarily measures hippocampus-dependent spatial learning during acquisition trials and spatial reference memory during probe trials after platform removal; readouts include escape latency, swim path length, swim speed, quadrant occupancy, platform-site crossings, and proximity to the former platform location.

Research Protocol for Microbiome Analysis
Microbiome analysis characterizes microbial communities in biological or environmental samples by measuring community composition, diversity, taxonomic structure, functional potential, and associations with host or environmental phenotypes. 16S rRNA gene amplicon sequencing is commonly used for bacterial and archaeal taxonomic profiling, while shotgun metagenomics provides higher taxonomic resolution and direct functional information, including microbial genes, pathways, viruses, fungi, and antimicrobial-resistance genes when sequencing depth and host-DNA contamination are adequately controlled. Microbiome results are strongly affected by sample collection, storage, DNA extraction, contamination, sequencing method, reference database, and bioinformatic pipeline; therefore, standardized protocols, negative controls, mock communities, and transparent analysis workflows are required. Unresolved issues include low-biomass contamination, compositional-data bias, inconsistent species-level c

Primary Embryonic Hippocampal Neuron Culture
Primary embryonic hippocampal neuron culture is an in vitro method in which hippocampi from embryonic rodents are dissected, enzymatically or mechanically dissociated, plated on adhesive substrates, and maintained in defined neuronal medium or in low-density sandwich/co-culture formats to support neuronal attachment, neurite extension, polarity formation, dendritic arborization, and synapse formation. The main readouts are cell survival, neuronal purity, neurite outgrowth, axon-dendrite polarization, synaptic marker development, and functional neuronal activity, assessed by phase-contrast microscopy, immunocytochemistry for neuronal/glial markers, live imaging, or electrophysiology depending on the downstream experiment.

Cell invasion
Cell invasion is the ability of cells to migrate from one area to another via the extracellular matrix. Cell invasion is the response of normal and cancer cells to chemical and mechanical stimuli. Before migrating to a new region, the extracellular matrix is degraded by proteases within the cell. Cell invasion often occurs during wound repair, vascularization and inflammation, abnormal tissue invasion, and tumor cell metastasis.

Cell Viability Determination by MTT Colorimetric Assay
The following protocol uses the MTT colorimetric assay as a classic literature-established method for assessing cell viability/metabolic activity in cultured mammalian cells. MTT[3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] is reduced by metabolically active cells to a colored formazan product; the amount of formazan is quantified spectrophotometrically and provides an indirect measure of metabolically active viable cells. Importantly, MTT reduction reflects cellular oxidoreductase/metabolic activity rather than an absolute direct count of living cells, so changes in cellular metabolism can alter the signal independently of cell number.
