Abstract: Methods, systems, and devices for automated feature selection and model generation are described. A device (e.g., a server, user device, database, etc.) may perform model generation for an underlying dataset and a specified outcome variable. The device may determine relevance measurements (e.g., stump R-squared values) for a set of identified features of the dataset and can reduce the set of features based on these relevance measurements (e.g., according to a double-box procedure). Using this reduced set of features, the device may perform a least absolute shrinkage and selection operator (LASSO) regression procedure to sort the features. The device may then determine a set of nested linear models—where each successive model of the set includes an additional feature of the sorted features—and may select a “best” linear model for model generation based on this set of models and a model quality criterion (e.g., an Akaike information criterion (AIC)).
Abstract: A method is provided for treating a recipient with a biological product obtained from at least one donor that may be the same as, or different from, the recipient.

Abstract: The presently claimed invention offers programmable and precise regulation of Cas9 functions by utilizing a set of compact Cas9 derivatives created by deleting conserved HNH and/or REC-C domains based on the structural information across variant class 2 CRISPR effectors. In addition, a novel strategy for engineering the dimeric gRNA-guided nuclease by splitting the mini-dSaCas9 and fusing the FokI domain right after the split point is claimed to increase the on-target DNA cleavage efficiency and potentially reduce the off-target effect because of a closer proximity of dimeric Fold nuclease to the target sequence. By combining the optimized and compact gRNA expression cassette and the downsized SaCas9 derivatives, the entire CRISPR/Cas system with different effector domains for transactivation, DNA cleavage and base editing is loaded into a single AAV virus. Such an all-in-one AAV-CRISPR/Cas9 system will be particularly appealing in biomedical applications that require safe and efficient delivery in vivo.

With the aid of the nanopore, a tag associated with the individual tagged nucleotide can be detected upon incorporation of the individual tagged nucleotide.

Abstract: Described herein are methods of enhancing chromosomal homologous recombination to stimulate a loss of heterozygosity at a gene locus of interest in a living cell. These methods are driven by an enhancer component and a target-specific endonuclease component and proceed through a mechanism whereby: exogenous donor DNA that is homologous to the gene locus of interest is not introduced into the living cell; the desired allele of the gene locus of interest remains uncleaved; and the undesired allele is either uncleaved, cleaved at a single location, or cleaved at multiple locations. These methods have numerous applications, including the repair of risk alleles for disease prevention, the correction of heterozygous mutations in dividing cells, the design of cancer therapeutics, and the design of novel gene-drive strategies.

Abstract: A Western Blot assay is performed by performing a probing process on a membrane containing target proteins, by contacting the membrane with a fluorescent resonant energy transfer (FRET) solution and allowing the probing process to proceed for a probing time period. The probing process results in a target protein becoming labeled with both a donor chromophore and an acceptor chromophore, which are effective as a donor-acceptor pair for FRET when so linked to the target protein. While performing the probing process, the labeled target proteins are measured by irradiating the membrane with an excitation light to excite the donor chromophores, wherein in each labeled target protein, the excited donor chromophore transfers energy to the acceptor chromophore by FRET and, in response, the labeled target protein emits an emission light. The intensity of the emission light is then measured. The light measured may be light emitted from the donor chromophore and/or light emitted from the acceptor chromophore.

Abstract: Methods and systems described herein involve using long cell-free DNA fragments to analyze a biological sample from a pregnant subject. The status of methylated CpG sites and single nucleotide polymorphisms (SNPs) is often used to analyze DNA fragments of a biological sample. A CpG site and a SNP are typically separated from the nearest CpG site or SNP by hundreds or thousands of base pairs. Finding two or more consecutive CpG sites or SNPs on most cell-free DNA fragments is improbable or impossible. Cell-free DNA fragments longer than 600 bp may include multiple CpG sites and/or SNPs. The presence of multiple CpG sites and/or SNPs on long cell-free DNA fragments may allow for analysis than with short cell-free DNA fragments alone. The long cell-free DNA fragments can be used to identify a tissue of origin and/or to provide information on a fetus in a pregnant female.
