Abstract: A nanosystem and methods of treating, including prophylactically, coronavirus infections, such as those caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), by administering such nanosystem to a patient is presented. The nanosystem may be comprised of a single or a combination of therapeutic agents, optionally encapsulated in a nanoparticle having a targeting moiety directed to the particular coronavirus. For CoV-2 infections, at least one therapeutic agent, such as the dual DPP4/ACE2 inhibitor sitagliptin, may optionally be encapsulated within a nanoparticle having a fatty acid such as linoleic acid, as the targeting moiety. Administration can occur intranasally prior to infection for prophylactic treatment or post-infection for treatment of the viral infection.

Abstract: A multi-functional broad-spectrum antiviral and anti-inflammatory nanosystem and methods of treating, including prophylactically, coronavirus infections, such as those caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), by administering such nanosystem to a patient is presented. The nanosystem may be comprised of a combination of therapeutic agents directed to the particular coronavirus encapsulated in a nanoparticle that is surface coated with a targeting moiety. For CoV-2 infections, an antiviral such as the PPAR-? agonist leriglitazone (LG) and an siRNA targeting a conserved sequence of the virus can be encapsulated within a nanoparticle surface coated with a fatty acid such as linoleic acid, as the targeting moiety. Administration can occur intranasally prior to infection for prophylactic treatment or post-infection for treatment of the viral infection.

Abstract: A 4D-perfused tumoroid-on-a-chip platform used in personalized cancer treatment. The platform includes a plate with a plurality of bottomless wells that resides atop a microfluidic channel layer, which in turn resides atop a surface acoustic wave (SAW) based sensor layer that is capable of measuring potential pH values of fluids disposed within the platform. The microfluidic channel layer includes a plurality of bioreactors, with each bioreactor including an inlet well, a culture well, and an outlet well. The inlet well, culture well, and outlet well form a closed system via fluid conduits spanning from the inlet well to the culture well, as well as from the culture well to the outlet well. Due to the fluid flow from the plate to the chip, and from the inlet well to the outlet well on the chip through the culture well, target cell (tumoroid) growth is promoted within the culture well.

Abstract: The present invention pertains to a strategy of selectively targeting oncolytic virotherapy, using either naturally occurring or genetically modified viruses by packaging them in mesenchymal stem cells (MSCs).

Abstract: A method of treating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), otherwise known as COVID-19, infection by administering nicotinic receptor antagonists and/or PPAR-? agonists is presented. A combination of mecamylamine, or an isomer thereof, and pioglitazone synergistically reduces replication of SARS-CoV-2 in virus-infected cells and also synergistically reduces inflammatory cytokines such as IL-6, IL-?, and TNF?, which have been associated with SARS-CoV-2 infection.

Abstract: Described herein are methods for neutralizing a virus. The methods involve interacting the virus with an oligochitosan or a derivative thereof having a molecular weight of at least 1 KDa and a degree of deacetylation of at least 1%. The methods described herein have numems applications with respect to the treatment or prevention of viral infections caused by a human immunodeficiency virus, a paramyxovirus, an orthomyxovirus, a coronavirus, or a filovirus as well as the detection and quantification of viral load. Also described herein are the synthesis of the oligochitosan and derivatives thereof.

Abstract: A multifunctional dendrimer nanoparticle and method of treating diseases of the posterior segment of the eye is presented. The functionalized polyamidoamine (PAMAM) dendrimer effectively delivers drugs and/or genes to the posterior eye, thereby providing for the effective, non-invasive, and topical treatment of diseased in the posterior eye. The multifunctional dendrimer nanoparticle has shRNA-encoding DNA and small molecule drug encapsulated cyclodextrin complexed to the outer surface of the dendrimer for delivery to the posterior segment of the eye.

Abstract: Method for increasing efficiency of a pathogen inactivation via enhancing UVC light absorption at such pathogen by multiple diffuse scattering of the light at a wall defining a substantially closed volume, thereby increasing a number of angles at which the pathogen is being irradiate as compared with a direct irradiation of the pathogen with a beam of such light.

Abstract: The present disclosure relates to compositions and uses thereof for preventing and treating respiratory syncytial vims (RSV) infection. In some aspects, disclosed herein is a method for preventing or treating respiratory syncytial vims (RSV) infection in a subject, comprising administering to the subject a therapeutically effective amount of a composition comprising a short-chain fatty acid.

Abstract: Disclosed are various embodiments of systems and methods of deep learning for colorectal polyp screening and providing a prediction of neoplasticity of a polyp.

Abstract: Compositions and methods for treating traumatic brain injury (TBI) are presented. Novel dendriplexes are formed from poly(amidoamine) (PAMAM) dendrimers complexed with shRNA encoding DNA plasmids encapsulating shRNA encoding chemokine ligand 20 (CCL20) gene, chemokine receptor 6 (CCR6) gene, or a combination thereof. The dendriplexes are dually administered, both intranasally and intravenously, prior to administration of stem cells, such as human mesenchymal stem cells (hMSCs) for the treatment of traumatic brain injury (TBI). Administration of the dendriplexes prior to stem cell administration resulted in a decrease in neurodegeneration, neuroinflammation, microgliosis and astrogliosis. In addition, a synergistic increase in brain derived trophic factor (BDNF) was shown by administration of the combination of dendriplex and stem cell administration.

Abstract: An in vitro microfluidic device includes a device configured to model a blood-brain barrier. The device includes a center well in fluidic communication with each of an inlet and an outlet. Each of the center well, inlet, and outlet includes a porous membrane that separates a “blood” portion (a fluid flow portion) from a “brain” portion (a fluid containing portion). The porous membrane is seeded with endothelial cells such as the human venule endothelial cells (HUVECs) on the blood side, and with astrocytes on the brain side, to accurately model the blood-brain barrier. Fluid flows between the inlet, the center well, and the outlet to test the permeability of the porous membrane, thereby providing an accurate in vitro model of a blood-brain barrier.
