  • Publication number: 20230133119
    Abstract: Herein is reported a class of chiral compounds with paradoxical effects on the androgen receptor (AR). The (R)-enantiomers behave like classical anti-androgens while the (S)-enantiomers activate AR signaling. In castration-resistant prostate cancer, the change during the course of therapy to growth in the presence of AR targeted therapeutics, a harbinger of progression to lethal disease, is commonly attributed to acquired mutations of the AR-ligand binding domain. This is the first report of an antagonist—agonist duality solely due to structural enantiomerism, without any modification to the AR binding site.

  • Publication number: 20230138764
    Abstract: Systems and methods are provided for increasing photon collection during imaging with a light-sheet fluorescence microscope. In one example, one or more adaptive optical elements may be positioned in a detection light path between a detection objective and an imaging sensor. A depth of field of the detection objective is adjusted as a function of a thickness of an excitation light-sheet used to illuminate a sample during imaging. As a result, the detection objective captures more fluorescence photons generated by light-sheet excitation.

  • Patent number: 11629320
    Abstract: Zebrafish are a powerful model for investigating cardiac repair due to their unique regenerative abilities, scalability, and compatibility with many genetic tools. However, characterizing the regeneration process in live adult zebrafish hearts has proved challenging because adult fish are opaque and explanted hearts in conventional culture conditions experience rapid declines in morphology and physiology. To overcome these limitations, we fabricated a fluidic device for culturing explanted adult zebrafish hearts with constant media perfusion that is also compatible with live imaging. Unlike hearts cultured in dishes for one week, the morphology and calcium activity of hearts cultured in the device for one week were largely similar to freshly explanted hearts.

  • Publication number: 20230111856
    Abstract: The first selective SuFEx antagonists to ?-opioid receptors (MOR) were developed by functionalizing an opioid scaffold with an SO2—F warhead. Our model, based on a MOR structure with antagonist ?-FNA, indicates the naloxone carbonyl as an advantageous point for derivatization as it is chemically accessible and is not involved in interaction with receptors. Of the three accessible Tyr residues in MOR pocket, Tyr77, Tyr130 and Tyr150, Tyr150 in proximity to the carbonyl of the docked naloxone was selected as a target, which resulted in the development of highly potent antagonists.

A controller actuates a subset of the concentric ring electrodes such that electrical control of focal length is achieved by selecting a group of electrodes to actuate so that acoustic waves generated from selected electrodes arrive at a desired focal length in-phase and interfere constructively to create a focal spot of high acoustic intensity. The patterned metal layer optionally includes a first central electrode that is surrounded by the first plurality of concentric ring electrodes.
