Abstract: Interferon-?-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: Disclosed herein are various bioreactor devices that mimic the mammalian joint. The bioreactor device can include a series of bioreactor chambers that contain different components of the joint, such as bone, cartilage, synovium, nerve and ligament. At least two different nutrient fluid circulation systems connect subsets of the bioreactor chambers to differentially supply nutrient fluids at concentrations optimized for the tissue that the fluid nourishes. For example, relatively hypoxic fluid can be supplied to synovium and cartilage to mimic oxygenation in the joint compartment, but normoxic fluid can be supplied to the bone and other components that have an arterial supply that provides higher oxygen concentrations. One or more or all of the bioreactor chambers can be supplied with separate inlets through which perturbation agents (such as drugs or other agents) can be introduced to model the effect of the perturbations on different components of the system.

Abstract: A method of managing data during execution of an application for use in a system that includes a host memory, a near memory, and a near device associated with the near memory. The application uses a working set of data that is distributed between the far memory and the near memory. The method includes counting a number of times that the near device accesses a unit of the working set of data from the far memory, determining whether the number of times exceeds a dynamically changing access counter threshold, wherein the dynamically changing access counter threshold is calculated dynamically based on a static threshold that is set for the system, and responsive to determining that the number of times exceeds the dynamically changing access counter threshold, migrating the unit of data from the far memory to the near memory.
