Abstract: Interferon-γ-inducible protein 10 (IP-10) peptides, IP-10 peptide variants and in silico designed C—X—C chemokine receptor 3 (CXCR3) peptide agonists are described. The small peptides can be used for inhibiting pathological tissue remodeling and treating fibrosis in a subject, such as a subject with fibrosis of the heart, lung, liver, kidney or skin. The peptide agonists can also be used to treat cardiovascular disease, including myocardial infarction and ischemia-reperfusion injury. Also described are in silico designed peptide antagonists that bind CXCR3 or ligands of CXCR3. These antagonist peptides block CXCR3 signaling by disrupting interaction of CXCR3 with its ligand. Antagonist peptides can be used, for example, to treat myocarditis and atherosclerosis. In additional embodiments agonists and antagonists of CXCR4 are disclosed.

Abstract: A biopolymer film is provided that comprises a combination of: crystalline nano cellulose (CNC)/esterified crystalline nano cellulose (ECNC) reinforced with chitosan. The two polymer components can be present in any ratio but an approximate CNC to ECNC 70:30 ratio is preferred. The chitosan component is derived from exoskeletons of crustaceans. Also provided are methods of preparing biopolymer film and preparing food packaging components from said biopolymer film. The CNC/ECNC mixture is dissolved in an ethanol solution and the chitin is dissolved in acetic acid and mixed together to form a polymer blend.

Abstract: A water filtration system is provided that comprises a combination of two components: silver nanoparticles immobilized on a porous carbon solid matrix and calcium carbonate silver nanoparticles. The silver nanoparticles immobilized on the porous carbon solid matrix are prepared in a one-step wet ball milling process that does not use an environmentally hazardous reducing agent or an organic stabilizer. The calcium carbonate in the calcium carbonate silver nanoparticles is preferably isolated from egg shells. The two filter components can be present in any ratio but an approximate 50:50 ratio is preferred. Also provided is an in situ method of preparing silver nanoparticles on active charcoal. Powdered activated charcoal and silver nitrate are mixed together in a mixture of ethanol and water to form a charcoal-silver nitrate solution which is then subjected to ball milling in the presence of polypropylene glycol to produce silver nanoparticles on active charcoal.

Abstract: A biopolymer blend is provided that comprises a combination of three components: poly (butylene adipate-co-terephthalate) (PBAT); agriculture sourced polylactic acid (PLA); and engineered proteinaceous eggshell nanoparticles. The two polymer components can be present in any ratio but an approximate 70:30 ratio is preferred. The engineered proteinaceous eggshell nanoparticles are preferably about 10-25 nanometers. Also provided are methods of preparing biopolymer film and packaging components. Pelleted poly (butylene adipate-co-terephthalate) and agriculture sourced polylactic acid (PLA) are dissolved in chloroform and mixed together to form a polymer blend, and engineered proteinaceous eggshell nanoparticles are incorporated into the polymer blend, which is then extruded to create a biopolymer film or component.

Abstract: Administration via inhalation of small peptides that mimic CXCL10 (FIBROKINE™ peptides) is described. The peptides can be administered as an aerosol, such as an aerosol with a droplet size small enough to reach lung alveoli. Use of the peptides to treat fibrosis, such as lung fibrosis, is described.

Abstract: A handle system includes a body extending between a first end and a second end. The handle system also includes a slot extending, at least partially, in the body, the slot forming a cavity. The handle system further includes a carrier arranged, at least partially, within the slot, the carrier further comprising a friction locker and at least one arm coupled to the friction locker, the at least one arm being rotatable about the friction locker. The handle system also includes a cap arranged on at least one of the first end or the second end. The handle system further includes a blade coupled to the at least one arm, the blade being rotatable about the axis between a retracted position where the blade is positioned within the slot and an extended position where the blade extends outwardly from the body.
