Publication number: 20220204463Abstract: Substituted nitrobenzothiazinones (BTZs) are potent antituberculosis prodrugs that are reductively activated to produce nitroso moieties that form covalent adducts with a cysteine residue of decaprenylphospholyl-?-D-ribose-2?-oxi-dase (DprE1) of Mycobacterium tuberculosis (Mtb). The resulting cell wall synthesis inhibition is lethal to Mtb, leading to consideration of development of BTZs for clinical use. The hydride-induced reduction of the nitroaromatic proceeds by reversible formation of the corresponding Meisenheimer complex. Herein we demonstrate that chemical reduction of BTZ043 with NaBD4 followed by reoxidation incorporates deuterium into the core nitro aromatic warhead. Subsequent reduction of the deuterated species is not affected, but, as expected, reoxidation is slowed by the deuterium isotope effect, thus prolonging the lifetime of the active nitroso oxidation state.Type: ApplicationFiled: April 3, 2020Publication date: June 30, 2022Applicant: University of Notre Dame du LacInventors: Marvin J. Miller, Viktor KRCHNAK, Rui LIU

Publication number: 20220182092Abstract: Aspects of the subject disclosure may include, for example, receiving, by a first radio module at a first location, a wireless signal, to obtain a first received RF signal. The wireless signal includes information originating at a remote transmitter and conveyed via a wireless channel. An envelope of the first received RF signal is detected by the first radio module without requiring a local oscillator, to obtain a first baseband signal. The first baseband signal may be filtered and/or amplified, after which it is provided to a processor. The processor also obtains a second digital signal from a second radio module receiving the wireless signal at a second location and determines an estimate of the information originating at the remote transmitter according to the first and second signals. Other embodiments are disclosed.Type: ApplicationFiled: February 25, 2022Publication date: June 9, 2022Applicants: AT&T Intellectual Property I, L.P., University of Notre Dame du LacInventors: Ralf Bendlin, Jonathan David Chisum, Nicholas Joseph Estes, Bertrand Martyn Hochwald, Aditya Chopra

Publication number: 20220166655Abstract: Aspects of the subject disclosure may include, for example, receiving a radio frequency (RF) signal having a carrier wave component that operates at a carrier frequency within a millimeter wave spectrum. The RF signal also includes an information component based on a phase shift keying (PSK) modulation of the carrier wave component. A local oscillator (LO) signal is obtained, which includes an LO frequency that approximates the carrier frequency. The received RF signal and the LO signal are combined without using signal multiplication to obtain a first combined output signal. The first combined output signal being detected via a non-linear energy detector to obtain a first detected signal. The first output signal includes information of the information component.

Patent number: 11293057Abstract: The invention provides an alternating current electrospray technology that can generate micron sized droplets in oil at very high throughput for emulsion or digital PCR (Polymerase Chain Reaction). This technology outperforms the throughput of the current gold standard in droplet generation using flow-focusing technology by at least a factor of 100. The design is simple and can generate a billion to a trillion monodispersed droplets in about one hour. This is much faster than flow-focusing which is limited to a few million droplets per hour. The droplet size and generation rate can also be easily adjusted by changing the voltage of the AC electric field. The range of produced droplet sizes is about 1-100 microns, wherein the droplets are monodispersed in size.Type: GrantFiled: May 9, 2017Date of Patent: April 5, 2022Assignee: University of Notre Dame du LacInventors: Hsueh-Chia Chang, David B.

Publication number: 20220002497Abstract: A highly permeable sorbent platform based on polysulfone and polystyrene-b-poly(acrylic acid) composite membranes. The membranes possess a fully interconnected network of poly(acrylic acid)-lined pores, which enables the surface chemistry to be tailored through sequential attachment of polyethyleneimine moieties and metal-binding terpyridine ligands. The polyethyleneimine moieties increase the saturation capacity, while the addition of terpyridine enables high-affinity binding to a diversity of transition metal ions. This membrane platform removes such metal contaminants from solution. The metal capture performance of the functionalized membranes persists even in high concentrations of competitive ions. Also, fluorescence quenching of the terpyridine moiety upon metal ion complexation offers an in-situ probe to monitor the extent of sorbent saturation.Type: ApplicationFiled: October 30, 2019Publication date: January 6, 2022Applicants: University of Notre Dame du Lac, Purdue Research FoundationInventors: Yizhou ZHANG, William A.

Patent number: 11168062Abstract: Clostridium difficile infection (CDI) is a public health threat that results in 14,000 annual deaths in the United States. Challenges involve the production of CDI spores that can remain dormant for years and the production of toxins that damage the gut. Current therapies for CDI include vancomycin and metronidazole, but neither inhibits spore or toxin production. Thus, recurrence of infection occurs in 25% of patients and there are no antibiotics that are effective for multiple recurrences. We describe oxadiazoles with activity against C. difficile, including the highly virulent NAP1/027 strain with increased production of toxins A and B, as well as the additional binary toxin. Oxadiazole 2 is poorly absorbed, thus advantageously achieving high concentrations in the gut. The compound targets peptidoglycan synthesis and inhibits vegetative cells, spores, and toxin production.Type: GrantFiled: September 12, 2017Date of Patent: November 9, 2021Assignee: University of Notre Dame du LacInventors: Mayland Chang, Shahriar Mobashery, Derong Ding
