Abstract: Disclosed are bruceolides for the treatment of cancer, and other diseases, selectively targeting unwanted cells. The disclosed bruceolides may include a site specific cleavable moiety inhibiting the chemotoxic activity until cleaved, i.e., removed, within and/or near a cancer to be treated. As to facilitate selective delivery to cancer tumors, the disclosed bruceolides may be loaded into, attached to or otherwise carried by nanoparticles.
Abstract: Compounds are provided herein which are emetine derivatives that can be used as prodrugs which selectively undergo activation to release emetine in specific cellular conditions. In one aspect, a blocking group is incorporated onto the emetine molecule by the derivization of the N2?-position with moieties that can be selectively removed by hydrolysis in the cancer/tumor microenvironment. Such compounds are less cytotoxic than emetine and are substantially inactive in non-cancerous cells. In one aspect, the compounds described herein can be used for the treatment of metastatic and non-metastatic cancers, including, for example, breast cancer, prostate cancer, lung cancer, and leukemia.

Abstract: A method, computer program, and computer system is provided for fault detection in an electrical network. An inductance between a reference point and a fault is determined at a first time based on measuring a fault current. A resistance between the reference point and the fault may be determined at a second time based on measuring a differential of the fault current as zero. A location of the fault may be identified based on the inductance and the resistance.
Abstract: The present disclosure provides novel computational methods for identifying potential therapeutic peptides as antivirals, and methods of using viral receptor-derived peptides as antivirals.

Abstract: Covalently linked linear polyethylenimine (PEI) clusters are provided that change conformation depending upon changes in counterion concentrations. The structures may be used for the storage, delivery, and/or transport of substances.
Abstract: Compounds and methods are described herein that are effective to modulate plant response (e.g., plant susceptibility) to environmentally-induced stress. The compounds and methods described herein advantageously may be used to modulate environmental stress resistance in a wide variety of plants. Environmental stresses include, for example, high light intensity (UV exposure), temperature (e.g., high heat), high soil salinity, and low soil moisture (e.g., drought). As used herein, environmental stresses include any conditions that result in increased generation of reactive oxygen species (ROS) and accumulation of ROS in the plant cells. The compounds described herein that are effective to modulate resistance to the stress prevent, directly or indirectly, or increase phosphorylation of Tyr248 of the RACK1A protein.

Abstract: A method, computer program, and computer system is provided for encrypting data or information represented by bits, numbers, used to encode images, text, or audio. For the case of an RGB image encryption applications, the data may be separated into its constituent channels before encryption. In addition to the standard encryption keys, another encryption isokey is generated based on an isounit using an algebraic isofield having a multiplicative identity value different than the number one. On the sender side, each of the channels is encrypted using the standard keys and the generated isokey. On the receiver side, each encrypted channel is decrypted before combining them to obtain the recovered RGB image. In addition to images, the cryptographic algorithm can also be used the encrypt data related to text, audio, and other file types.
