  • Publication number: 20240157057
    Abstract: A real-time drug injection time duration measurement system includes a sound transducer, a waveform shaping circuit operably coupled therewith, a pulse clamping circuit operably coupled with the waveform shaping circuit, and a timer operably coupled with the pulse clamping circuit. The sound transducer detects a first sound associated with drug delivery initiation and a second sound associated with drug delivery completion and is further converts the detected first and second sounds into a first electronic waveform and a second electronic waveform, respectively. The waveform shaping circuit converts the first and second waveforms into a first pulse and a second pulse, respectively. The pulse clamping circuit triggers upon receiving the first pulse and generate a regenerated pulse. The timer initiates upon receiving the regenerated pulse and stop upon receiving a subsequent regenerated pulse via the pulse clamping circuit.

  • Publication number: 20230211042
    Abstract: This disclosure relates to pectin-based polymer compositions and methods of use thereof to cover, protect, and seal injuries, e.g., surgical wounds, in a mesothelial tissue. The methods include obtaining a bioadhesive pectin-based polymer composition including a complex of high-methoxyl pectin (HMP) and carboxymethylcellulose (CMC) in a ratio from about 10 to 1 to 1 to 10 by weight; applying the composition to an injured mesothelial tissue; and applying pressure for at least one minute to enable the composition to bind to the mesothelial tissue.

  • Publication number: 20210024953
    Abstract: Methods and compositions are provided for generating targeted genetic modifications on the Y chromosome or a challenging target locus. Compositions include an in vitro culture comprising an XY pluripotent and/or totipotent animal cell (i.e., XY ES cells or XY iPS cells) having a modification that decreases the level and/or activity of an Sry protein; and, culturing these cells in a medium that promotes development of XY F0 fertile females. Such compositions find use in various methods for making a fertile female XY non-human mammal in an F0 generation.

  • Patent number: 9885058
    Abstract: Methods and compositions are described for making phenotypically female fertile animals from XY donor cells and suitable host embryos. Culture media and methods are provided for maintaining XY donor cells in culture that after introduction into a host embryo and gestation in a suitable host will result in fertile XY female animals. Methods and compositions are described for making fertile female animals in an F0 generation from a donor XY cell and a host embryo, as are methods for making F1 progeny that are homozygous for a modification from a heterozygous F0 fertile male and a heterozygous F0 fertile female sibling.

    Abstract: Methods of creating mutations in genomic exons by inserting introns into the genomic exons via homologous recombination. Also, methods are provided for introducing modifications into genomic exons by inserting introns into the genomic exons via homologous recombination such that a mature mRNA transcript produced from a genomic region of the genome comprising the genomic exon does not contain the modification are provided. The methods provide for a rapid method for introducing mutations and/or modifications of any type into a mammalian cell genome.
