    Abstract: Formulations for treating or preventing neuronal damage and/or the associated cognitive decline or impairment, caused by Alzheimer's disease and/or other neurodegenerative diseases, contain a therapeutic agent and a pharmaceutically acceptable carrier, wherein the therapeutic agent is dissolved in the pharmaceutically acceptable carrier. The formulations provide a safe, stable, convenient way to store and deliver high concentrations of the therapeutic agent, particularly when the therapeutic agent is lipophilic. The therapeutic agent can be a neurosteroid, a derivative or analogue thereof, or a pharmaceutically acceptable salt of the neurosteroid or its derivative or analogue. The pharmaceutically acceptable carrier can contain water, one or more lipophilic compounds, a surfactant, and optionally a co-surfactant. Generally, the carrier forms a stable microemulsion.

  • Patent number: 11359192
    Abstract: The present invention relates to a method of preparing a DNA library derived from FFPE tissue using endonucleases, and the majority of general clinical samples are FFPE tissues and in case of old FFPE tissues, DNA library preparation often fails and NGS analysis becomes difficult and therefore there is a desperate need to overcome these problems. S1 nucleases are enzymes which specifically cleave only single-stranded DNA and in almost all FFPEs, there is a nick in the dsDNA everywhere, which can be the target of S1 nucleases. In the process of extracting gDNA from FFPE tissues, since when S1 nucleases are treated and eluted under appropriate conditions during elution, a DNA fragment can be obtained with DNA having a size suitable for DNA library preparation together with the DNA extraction, the Covaris fragmentation process can be omitted and cost and time can be reduced.
