  • Publication number: 20230337647
    Abstract: The present disclosure provides transgenic nematode systems for assessing function of heterologous genes, their variants and drug discovery. The transgenic nematodes contain a heterologous gene that is inserted via homologous recombination at the native locus replacing and removing the nematode ortholog, wherein expression of the heterologous gene rescues function of the removed nematode ortholog and a transgenic control animal is provided. The heterologous gene may be further modified to provide a variant, such as a human clinical variant, whereby a transgenic test animal is provided. Those transgenic test animals are used in methods to assess function of the heterologous variant and drug screens to find therapeutic candidates reversing deviant activity back to wildtype.

  • Publication number: 20230146102
    Abstract: The present disclosure provides transgenic non-human animal (e.g., nematode) systems for assessing heterologous polygenic or monogenic phenotypes, their variants and drug discovery. The transgenic non-human animals (e.g., nematodes) contain a first heterologous polypeptide coding sequence and a second heterologous polypeptide coding sequence (a plurality of heterologous polypeptide coding sequences), wherein the first and second heterologous polypeptide coding sequences are integrated into the host animal genome, and wherein expression of the first and second heterologous polypeptide coding sequence contribute to the heterologous phenotype. The plurality of heterologous polypeptide coding sequences are interrelated wherein their expression products, directly or indirectly, contribute or lead to an observable phenotype.

  • Publication number: 20210277421
    Abstract: The present disclosure provides homologous recombination reporter nucleic acid construct reagents for increasing the likelihood of detecting successful modification of a specific sequence in chromosomal DNA of a host cell via homologous recombination. The homologous recombination reporter constructs contain a sequence element inserted within the coding sequence for a reporter gene resulting in a mutated reporter gene. The sequence element is removed via homologous recombination based on the presence of two homology regions present in the reporter construct.

  • Patent number: 11011908
    Abstract: To join two sources in parallel, the second source output is lowered and then raised until two diodes providing an auxiliary path are passing current. This can reduce current spikes. Alternatively, the diodes can reversed, the voltage raised, and the lowered until diose are passing current.

  • Patent number: 5383107
    Abstract: A control unit for an inverter determines an objective function based upon harmonic content in a minimum number of the phase-to-phase AC voltages produced by the inverter and controls the switches of the inverter so as to minimize the objective function to thus control the harmonic content in the inverter output voltages.The objective function may be defined according to the following equation: ##EQU1## where W.sub.k are scaler weighting factors, A.sub.kA, A.sub.kB and A.sub.kC are the Fourier cosine coefficients of the kth harmonic of the inverter phase A, B and C outputs, B.sub.kA, B.sub.kB and B.sub.kC are the Fourier sine coefficients of the kth harmonic of the inverter phase A, B and C outputs, k is the number of the controlled odd harmonic (i.e., k=1, 3, 5 . . . ), and NHARM is the number of the highest controlled odd harmonic.
