OBJECTIVE To evaluate the potential and correlation between near-infrared fluorescence (NIRF) imaging using cyanine 5.5 conjugated with hydrophobically modified glycol chitosan nanoparticles (HGC-Cy5.5) and (18)F-fluorodeoxyglucose-positron emission tomography ((18)F-FDG-PET) imaging of collagen-induced arthritis (CIA). MATERIALS AND METHODS We used 10 CIA and 3 normal mice. Nine days after t...

Transforming growth factor-β1 (TGF-β1) is critical in controlling inflammatory responses and the prevention of autoimmune diseases. Although the effect of TGF-β1 on macrophages from normal mice or rats has been established, little attention has been paid to its effect on disease conditions. In the present study, we investigated the regulatory effect, and possible mechanism, of TGF-β1 exposure o...

The involvement of granulocyte-macrophage CSF (GM-CSF) in collagen-induced arthritis (CIA) was examined using GM-CSF-deficient mice. Although CIA is generally considered to be restricted to mice of the H-2q or H-2r haplotypes, we examined the role of GM-CSF in the CIA model using GM-CSF-deficient (-/-) and wild-type (+/+) mice on a C57BL/6 (H-2b) background. Mice were immunized by intradermal i...

Autoimmune diseases, like rheumatoid arthritis, result from a dysregulation of the immune response culminating in hyperactivation of effector cells leading to immune-mediated injury. To maintain an appropriate immune response and prevent the emergence of autoimmune disease, activation signals must be regulated by inhibitory pathways. Biochemical and genetic studies indicate that the type IIB lo...

We study the use of the-calculus for semantical descriptions of higher-order concurrent languages with state. As an example, we choose Concurrent Idealized ALGOL (CIA). CIA is particularly interesting as, yet being a core language, it combines imperative and parallel features with a procedural mechanism of full higher order. It can thus be used as a formal model for concurrent programs as, e.g....

Confidentiality, Integrity, and Availability are three sides of the famous CIA security triangle. Since the evoting systems are built from particular components, the CIA security triangle of these systems has particular definitions for each side. This paper presents these CIA security definitions and criteria which each state-of-the-art electronic voting system must meet based on the view point...

In the exploration of potential therapeutic agents for rheumatoid arthritis (RA), DBA/1J mice are used as the RA model of collagen-induced arthritis (CIA). Phloretin, a flavonoid compound extracted from Prunus mandshurica, has been found to exhibit anti-inflammatory activity, making it a potential candidate for treatment of RA. The objective of this study was to evaluate the therapeutic effects...

Using a murine model that mimics chemotherapy-induced alopecia (CIA) in humans particularly well, we show here that in contrast to previously reported CIA-protective effects in neonatal rats, topical calcitriol does not prevent CIA in adolescent mice but enhances the regrowth of normally pigmented hair shafts. When, prior to injecting 1 X 120 mg/kg cyclophosphamide i.p., 0.2 microg calcitriol o...

We investigated whether oral administration of curcumin suppressed type II collagen-induced arthritis (CIA) in mice and its effect and mechanism on matrix metalloproteinase (MMP)-1 and MMP-3 production in CIA mice, RA fibroblast-like synoviocytes (FLS), and chondrocytes. CIA in mice was suppressed by oral administration of curcumin in a dose-dependent manner. Macroscopic observations were confi...

The physiologic function of adipose tissue is altered by the host's inflammatory response; the implications for maintaining human health and regulating inflammation-associated disease progression are ill defined. However, this cannot be investigated in humans, therefore the use of animal models is required. With the aim to determine morphological and molecular alterations to perivascular and or...
