  • Publication number: 20240127967
    Abstract: Methods of modeling the in vivo efficacy of drug combinations for the treatment or prevention of viral infection are described. The described methods combine data for single drugs and drug combinations from pharmacokinetic, pharmacodynamic, and viral dynamics models under a series of estimated in vivo drug potencies to provide predictions of the in vivo effects of the drug combinations. These predictions can be used to more accurately select drugs and drug treatment regimens that can be successful in controlling viral infection in animal studies, clinical trials and in medical or veterinary interventions. Also described is a method of treating or preventing filovirus infections using combinations of orally available drugs based on predictions from the modeling methods.

  • Patent number: 11954578
    Abstract: Systems and methods for denoising a magnetic resonance (MR) image utilize an unsupervised deep convolutional neural network (U-DCNN). Magnetic resonance (MR) image data of an area of interest of a subject can be acquired, which can include noisy input images that comprise noise data and noise free image data. For each of the noisy input images, iterations can be run of a converging sequence in an unsupervised deep convolutional neural network. In each iteration, parameter settings are updated; the parameter settings are used in calculating a series of image feature sets with the U-DCNN. The image feature sets predict an output image. The converging sequence of the U-DCNN is terminated before the feature sets predict a respective output image that replicates all of the noise data from the noisy input image. Based on a selected feature set, a denoised MR image of the area of interest of the subject can be output.

  • Publication number: 20240100081
    Abstract: It is disclosed herein that RPE degeneration in human cell culture and in mouse models is driven by a non-canonical inflammasome pathway that results in activation of caspase-4 (also known as caspase-11 in mouse) and caspase-1, and requires cyclic GMP-AMP synthase (cGAS)-dependent interferon-? (IFN-?) production and gasdermin D-dependent interleukin-18 (IL-18) secretion. Reduction of DICER1 or accumulation of Alu RNA triggers cytosolic escape of mitochondrial DNA, which engages cGAS. Collectively, these data highlight an unexpected role for cGAS in responding to mobile element transcripts, reveal cGAS-driven interferon signaling as a conduit for mitochondrial damage-induced NLRP3 activation, and expand the immune sensing repertoire of cGAS and caspase-4 to non-infectious human disease. Coupled with the unexpected result that caspase-4, gasdermin D, IFN-?, and cGAS are elevated in the RPE of human eyes with geographic atrophy, these findings also identify new targets for a major cause of blindness.
