  • Publication number: 20230243555
    Abstract: A passive thermal regulation system includes a substrate and a coating. The coating is positioned to encapsulate at least a portion of the substrate. The coating includes a first hydrogel layer and a second hydrogel layer. The first hydrogel layer has a plurality of carbon materials configured to absorb a solar radiation. The second hydrogel layer includes a hydrogel that is different from the first hydrogel layer. The coating, at a first temperature, causes the passive thermal regulation system to passively switch from a solar reflective state to solar absorber state to permit the plurality of carbon materials to absorb the solar radiation. At a second temperature, the coating causes the system to passively switch from the solar absorber state to the solar reflective state where the hydrogel of the second hydrogel layer inhibits the solar radiation from absorption. The second temperature is greater than the first temperature.

  • Publication number: 20230197099
    Abstract: Improved systems and methods are provided herein for extracting target speech from audio signals that can contain masking speech or other unwanted noise content. These systems and methods include detection of target speech in an input signal by detecting elevated frequency content in the signal above a threshold frequency. Portions of the signal determined to contain such elevated high frequency content are then used to generate audio filters to extract target speech from subsequently-obtained audio signals. This can include performing non-negative matrix factorization to determine a set of basis vectors to represent noise content in the spectral domain and then using the set of basis vectors to decompose subsequently-obtained audio signals into noise signals that can then be removed from the audio signals.

  • Publication number: 20230183252
    Abstract: New synthetic methods to provide access to previously unexplored functionality at the C8 position of substituted imidazo[5,1-d][1,2,3,5]tetrazines of Formula I. Through synthesis and evaluation of a suite of compounds with a range of aqueous stabilities (from 0.5 to 40 hours), a predictive model for imidazotetrazine hydrolytic stability based on the Hammett constant of the C8 substituent was derived. Promising compounds were identified that possess activity against a panel of GBM cell lines, appropriate hydrolytic and metabolic stability, and brain-to-serum ratios dramatically elevated relative to TMZ, leading to lower hematological toxicity profiles and superior activity to TMZ in a mouse model of GBM.

  • Patent number: 11667621
    Abstract: A genus of proteolysis-targeting chimeras (PROTACs)-type compounds/antiestrogens has now been found that act as selective estrogen receptor degraders (SERDs) and estrogen receptor antagonists by degrading and antagonizing ERa in breast cancer cells. The compounds are of the following genus: The compounds described herein exhibit anti-proliferative effects, and are potentially useful, alone or in combination with other therapies, for the treatment of breast cancer. In general, these compounds combine a tight binding ERa targeting ligand tethered to a recognition motif or degron. Once bound, the degron recruits destructive cellular components and the targeted receptor (i.e., ERa) is degraded (i.e., destroyed) or antagonized.

  • Patent number: 11664093
    Abstract: Catalyst design in asymmetric reaction development has traditionally been driven by empiricism, wherein experimentalists attempt to qualitatively recognize structural patterns to improve selectivity. Machine learning algorithms and chemoinformatics can potentially accelerate this process by recognizing otherwise inscrutable patterns in large datasets. Herein we report a computationally guided workflow for chiral catalyst selection using chemoinformatics at every stage of development. Robust molecular descriptors that are agnostic to the catalyst scaffold allow for selection of a universal training set on the basis of steric and electronic properties. This set can be used to train machine learning methods to make highly accurate predictive models over a broad range of selectivity space. Using support vector machines and deep feed-forward neural networks, we demonstrate accurate predictive modeling in the chiral phosphoric acid-catalyzed thiol addition to N-acylimines.

  • Publication number: 20230158019
    Abstract: The discovery of mutant or fusion kinases that drive oncogenesis, and the subsequent approval of specific inhibitors for these enzymes, has been instrumental in the management of some cancers. However, acquired resistance remains a significant problem in the clinic, limiting the long-term effectiveness of most of these drugs. Herein is demonstrated a strategy to overcome this resistance through drug-induced MEK cleavage (via direct procaspase-3 activation) combined with targeted kinase inhibition. This combination effect is shown to be general across diverse tumor histologies (melanoma, lung cancer, and leukemia) and driver mutations (mutant BRAF or EGFR, fusion kinases EML4-ALK and BCR-ABL). Caspase-3-mediated degradation of MEK kinases results in sustained pathway inhibition and substantially delayed or eliminated resistance in cancer cells in a manner superior to combinations with MEK inhibitors.

A sample mixes with a lysis medium and a nucleic acid amplification medium in the sample preparation module and then flows into a plurality of microfluidic chambers in the amplification module. The microfluidic chambers have disposed therein primers configured to initiate amplification of one or more target nucleic acid sequences corresponding to one or more pathogens. The sample carrier is inserted into an apparatus that includes a plurality of Sight sources and a camera. The light sources illuminate the microfluidic chambers with excitation light, a fluorophore emits fluorescence light indicative of nucleic acid amplification in response to the excitation-light, and the camera captures images of the microfluidic chambers. A target nucleic acid sequence in the sample is indicated by the images showing an increasing fluorescence in a microfluidic chamber that has the primers for that sequence.
