Published: February 2010

Using tissue engineering, a complex of neural stem cells (NSCs) and collagen type I was transplanted for the therapy of cerebral ischemic injury. NSCs from E14 d rats were dissociated and cultured by neurosphere formation in serum‐free medium in the presence of basic fibroblast growth factor (bFGF), then seeded onto collagen to measure cell adhesive ability. BrdU was added to the culture medium to label the NSCs. Wistar rats (n=100) were subjected to 2‐hour middle cerebral artery occlusion. After 24 hours of reperfusion, rats were assigned randomly to five groups: NSCs‐collagen repair group, NSCs repair group, unseeded collagen repair group, MCAO medium group, and sham group. Neurological, immunohistological and electronic microscope assessments were performed to examine the effects of these treatments. Scanning electronic microscopy showed that NSCs assemble in the pores of collagen. At 3, 7, 15, and 30 d after transplantation of the NSC‐collagen complex, some of the engrafted NSCs survive, differentiate and form synapses in the brains of rats subjected to cerebral ischemia. Six d after transplantation of the NSC‐collagen complex into the brains of ischemic rats, the collagen began to degrade; 30 d after transplantation, the collagen had degraded completely. The implantation of NSCs and type I collagen facilitated the structural and functional recovery of neural tissue following ischemic injury. Anat Rec, 2010. © 2010 Wiley‐Liss, Inc.

Published: February 2010

Objective

The aim of this study was to quantitate risk and to examine heterogeneity for HLA at high resolution in patients with the most common subtypes of juvenile idiopathic arthritis (JIA), IgM rheumatoid factor–negative polyarticular JIA and oligoarticular JIA. Use of 4‐digit comprehensive HLA typing enabled great precision, and a large cohort allowed for consideration of both age at disease onset and disease subtype.

Methods

Polymerase chain reaction–based high‐resolution HLA typing for class I and class II loci was accomplished for 820 patients with JIA and 273 control subjects. Specific HLA epitopes, potential interactions of alleles at specific loci and between loci (accounting for linkage disequilibrium and haplotypic associations), and an assessment of the current International League of Associations for Rheumatology classification criteria were considered.

Results

An HLA–DRB1/DQB1 effect was shown to be exclusively attributable to DRB1 and was similar between patients with oligoarticular JIA and a younger subgroup of patients with polyarticular JIA. Furthermore, patients with polyarticular JIA showed age‐specific related effects, with disease susceptibility in the group older than age 6 years limited to an effect of the HLA–DRB1*08 haplotype, which is markedly different from the additional susceptibility haplotypes, HLA–DRB1*1103/1104, found in the group with oligoarticular JIA and the group of younger patients with polyarticular JIA. Also in contrast to findings for oligoarticular JIA, patients with polyarticular arthritis had no evidence of an HLA class I effect. Markers associated with a reduced risk of disease included DRB1*1501, DRB1*0401, and DRB1*0701. DRB1*1501 was shown to reduce risk across the whole cohort, whereas DRB1*0401 and DRB1*0701 were protective for selected JIA subtypes. Surprisingly, the disease predisposition mediated by DPB1*0201 in individuals without any disease‐predisposing DRB1 alleles was great enough to overcome even the very strong protective effect observed for DRB1*1501.

Conclusion

Inherited HLA factors in JIA show similarities overall as well as differences between JIA subtypes.
Is the incidence of rheumatoid arthritis rising?: Results from Olmsted County, Minnesota, 1955–2007
Authors: Myasoedova Elena , Crowson Cynthia S. , Kremers Hilal Maradit , Therneau Terry M. , Gabriel Sherine E.
Published: February 2010

Objective

To examine trends in the incidence and prevalence of rheumatoid arthritis (RA) from 1995 to 2007.

Methods

To augment our preexisting inception cohort of patients with RA (1955–1994), we assembled a population‐based incidence cohort of individuals ≥18 years of age who first fulfilled the American College of Rheumatology 1987 criteria for the classification of RA between January 1, 1995 and December 31, 2007 and a cohort of patients with prevalent RA on January 1, 2005. Incidence and prevalence rates were estimated and were age‐and sex‐adjusted to the white population in the US in 2000. Trends in incidence rates were examined using Poisson regression methods.

Results

The 1995–2007 incidence cohort comprised 466 patients (mean age 55.6 years), 69% of whom were female and 66% of whom were rheumatoid factor positive. The overall age‐ and sex‐adjusted annual RA incidence was 40.9/100,000 population. The age‐adjusted incidence in women was 53.1/100,000 population (versus 27.7/100,000 population in men). During the period of time from 1995 to 2007, the incidence of RA increased moderately in women (P = 0.02) but not in men (P = 0.74). The increase was similar among all age groups. The overall age‐ and sex‐adjusted prevalence on January 1, 2005 was 0.72% (95% confidence interval [95% CI] 0.66, 0.77), which is an increase when compared with a prevalence of 0.62% (95% CI 0.55, 0.69) in 1995 (P < 0.001). Applying the prevalence on January 1, 2005 to the US population in 2005 showed that an estimated 1.5 million US adults were affected by RA. This is an increase from the previously reported 1.3 million adults with RA in the US.

Conclusion

The incidence of RA in women appears to have increased during the period of time from 1995 to 2007. The reasons for this recent increase are unknown, but environmental factors may play a role. A corresponding increase in the prevalence of RA was also observed.
Inducible costimulator ligand regulates bleomycin‐induced lung and skin fibrosis in a mouse model independently of the inducible costimulator/inducible costimulator ligand pathway
Authors: Tanaka Chihiro , Fujimoto Manabu , Hamaguchi Yasuhito , Sato Shinichi , Takehara Kazuhiko , Hasegawa Minoru
Published: February 2010

Objective

Systemic sclerosis is a connective tissue disease characterized by fibrosis of the skin and internal organs, including the lungs. Inducible costimulator (ICOS), which is expressed on activated T cells, and its ligand ICOSL, which is expressed on antigen‐presenting cells, have been considered a single receptor–ligand pair. Although the ICOS/ICOSL pathway is known to play various roles in adaptive immunity, its roles in innate immunity and tissue fibrosis remain unknown.

Methods

We assessed the roles of ICOS and ICOSL in tissue fibrosis by administering bleomycin intratracheally or intradermally into mice deficient in ICOS and/or ICOSL. Tissue fibrosis was evaluated by histologic or biochemical examination.

Results

ICOS deficiency attenuated the lung and skin fibrosis, whereas ICOSL deficiency aggravated it. Mice deficient in both ICOS and ICOSL exhibited accelerated fibrosis, reflecting a dominant role of ICOSL over ICOS in this model. Interestingly, ICOSL expression on macrophages and B cells derived from bronchoalveolar lavage fluid was significantly elevated in ICOS‐deficient mice as compared with wild‐type mice during this process. Thus, the levels of ICOSL expression on B cells and macrophages were inversely associated with the severity of tissue fibrosis.

Conclusion

Our results indicate that ICOSL expression on antigen‐presenting cells plays a previously unknown regulatory role during the development of bleomycin‐induced tissue fibrosis that is independent of the ICOS/ICOSL pathway. Further studies will be needed to clarify the roles of ICOS and ICOSL in the development of systemic sclerosis.
Simvastatin inhibits cytokine‐stimulated Cyr61 expression in osteoblastic cells: A therapeutic benefit for arthritis
Authors: Kok Sang‐Heng , Hou Kuo‐Liang , Hong Chi‐Yuan , Wang Juo‐Song , Liang Po‐Chin , Chang Cheng‐Chi , Hsiao Michael , Yang Hsiang , Lai Eddie Hsiang‐Hua , Lin Sze‐Kwan
Published: February 2010

Objective

To examine the effects of proinflammatory cytokines on Cyr61 expression in osteoblastic cells and the modulatory action of simvastatin, to assess the role of CREB in Cyr61 induction, and to investigate the relationship of osteoblastic expression of Cyr61 to disease progression in experimental arthritis.

Methods

Cyr61 expression and CREB phosphorylation at serine 133 were examined by Western blotting. Promoter activity of Cyr61 was assessed by luciferase assay with promoter deletion/mutagenesis and forced expression/gene silencing of CREB. Interaction between CREB and the Cyr61 promoter was evaluated by electrophoretic mobility shift assay and chromatin immunoprecipitation. CCL2 expression was examined by Northern blotting and enzyme‐linked immunosorbent assay. In rats with collagen‐induced arthritis (CIA), osteoblastic expression of Cyr61 was examined by immunohistochemistry, and disease progression was assessed by clinical, radiographic, and histologic examination.

Results

In primary human osteoblasts and U2OS cells, Cyr61 expression stimulated by tumor necrosis factor α, interleukin‐1β (IL‐1β), oncostatin M (OSM), and other IL‐6–family cytokines was suppressed by simvastatin. In U2OS cells, simvastatin inhibited OSM‐induced CREB phosphorylation and CREB–DNA binding. Knockdown of CREB by short hairpin RNA reduced Cyr61 synthesis. OSM‐induced Cyr61 promoter activation was dependent on CRE–CREB interaction and inhibited by simvastatin. Cyr61 enhanced CCL2 expression by U2OS cells. Intraarticular injection of simvastatin inhibited CIA progression and diminished the number of Cyr61+ osteoblasts and infiltrating macrophages.

Conclusion

Simvastatin inhibited cytokine‐stimulated Cyr61 expression in osteoblastic cells and suppressed disease progression and osteoblastic expression of Cyr61 in inflammatory arthritis. This finding indicates that simvastatin may have potential as a therapeutic agent for inflammatory arthritis.
Analysis of intracellular methotrexate polyglutamates in patients with juvenile idiopathic arthritis: Effect of route of administration on variability in intracellular methotrexate polyglutamate concentrations
Authors: Becker Mara L. , van Haandel Leon , Gaedigk Roger , Lasky Andrew , Hoeltzel Mark , Stobaugh John , Leeder J. Steven
Published: February 2010

Objective

Intracellular methotrexate (MTX) polyglutamates (MTXGlu) have been shown to be potentially useful biomarkers of clinical response in adult patients with rheumatoid arthritis. The present study was undertaken to measure intracellular MTXGlu concentrations in a cohort of patients with juvenile idiopathic arthritis (JIA) to determine the predictors of MTXGlu variability in these patients.

Methods

Blood samples were obtained from patients with JIA who were being treated with a stable dose of MTX for ≥3 months. Clinical data were collected by chart review. Concentrations of MTXGlu1–7 in red blood cell lysates were quantitated using an innovative ion‐pairing chromatography procedure, with detection by mass spectrometry.

Results

Patients with JIA from a single center (n = 99; mean ± SD age 117.8 ± 56.5 months, 69 female) were included in the analysis. The mean ± SD dose of MTX was 0.51 ± 0.25 mg/kg per week, with a median treatment duration of 18 months (interquartile range 3–156 months). MTX was administered subcutaneously in 66 patients (67%). Fifty‐six patients (57%) had active arthritis at the time of the clinic visit. Total intracellular MTXGlu (MTXGluTOT) concentrations varied 40‐fold, with a mean ± SD total concentration of 85.8 ± 48.4 nmoles/liter. Concentrations of each MTXGlu subtype (MTXGlu1–7) were measured individually and as a percentage of MTXGluTOT in each patient. MTXGlu3 was the most prominent subtype identified, comprising 42% of MTXGluTOT, and the interindividual variability in the concentration of MTXGlu3 was the most highly correlated with that of MTXGluTOT (r = 0.96). The route of MTX administration was significantly associated with MTXGlu1–5 subtypes; higher concentrations of MTXGlu1 + 2 were observed in patients receiving oral doses of MTX, whereas higher concentrations of MTXGlu3–5 were observed in patients receiving subcutaneous doses of MTX (P < 0.0001).

Conclusion

In this cohort of patients with JIA, the MTXGluTOT concentration varied 40‐fold. Individual MTXGlu metabolites (MTXGlu1–7), which have, until now, not been previously reported in patients with JIA, were detected. The route of MTX administration contributed to the variability in concentrations of MTXGlu1–5.
Loss of cartilage structure, stiffness, and frictional properties in mice lacking PRG4
Authors: Coles Jeffrey M. , Zhang Ling , Blum Jason J. , Warman Matthew L. , Jay Gregory D. , Guilak Farshid , Zauscher Stefan
Published: February 2010

Objective

To assess the role of the glycoprotein PRG4 in joint lubrication and chondroprotection by measuring friction, stiffness, surface topography, and subsurface histology of the hip joints of Prg4−/− and wild‐type (WT) mice.

Methods

Friction and elastic modulus were measured in cartilage from the femoral heads of Prg4−/− and WT mice ages 2, 4, 10, and 16 weeks using atomic force microscopy, and the surface microstructure was imaged. Histologic sections of each femoral head were stained and graded.

Results

Histologic analysis of the joints of Prg4−/− mice showed an enlarged, fragmented surface layer of variable thickness with Safranin O–positive formations sometimes present, a roughened underlying articular cartilage surface, and a progressive loss of pericellular proteoglycans. Friction was significantly higher on cartilage of Prg4−/− mice at age 16 weeks, but statistically significant differences in friction were not detected at younger ages. The elastic modulus of the cartilage was similar between cartilage surfaces of Prg4−/− and WT mice at young ages, but cartilage of WT mice showed increasing stiffness with age, with significantly higher moduli than cartilage of Prg4−/− mice at older ages.

Conclusion

Deletion of the gene Prg4 results in significant structural and biomechanical changes in the articular cartilage with age, some of which are consistent with osteoarthritic degeneration. These findings suggest that PRG4 plays a significant role in preserving normal joint structure and function.
A simple and efficient device for demonstrating cross‐sectional anatomy of the head
Authors: Zamarioli Ariane , Demaman Aline Santos , Bim Waldeci Roberto , Homem Jefferson Mallman , Thomazini Jose Antonio
Published: February 2010

Described in this article is a novel device that facilitates study of the cross‐sectional anatomy of the human head. In designing our device, we aimed to protect sections of the head from the destructive action of handling during anatomy laboratory while also ensuring excellent visualization of the anatomic structures. We used an electric saw to create 15‐mm sections of three cadaver heads in the three traditional anatomic planes and inserted each section into a thin, perforated display box made of transparent acrylic material. The thin display boxes with head sections are kept in anatomical order in a larger transparent acrylic storage box containing formaldehyde solution, which preserves the specimens but also permits direct observation of the structures and their anatomic relationships to each other. This box‐within‐box design allows students to easily view sections of a head in its anatomical position as well as to examine internal structures by manipulating individual display boxes without altering the integrity of the preparations. This methodology for demonstrating cross‐section anatomy allows efficient use of cadaveric material and technician time while also giving learners the best possible handling and visualization of complex anatomic structures. Our approach to teaching cross‐sectional anatomy of the head can be applied to any part of human body, and the value of our device design will only increase as more complicated understandings of cross‐sectional anatomy are required by advances and proliferation of imaging technology.

Petri nets based FPGA controller of PDP sustainer with half‐voltage energy recovery circuit
Authors: Kuo Jian‐Long , Chao Kai‐Lun , Lee Li‐Shiang
Published: February 2010

This paper proposes a FPGA controller design of a driver circuit based Petri nets for the Plasma Display Panel (PDP). In such a driver circuit, complicated control logic is required in the PDP sustainer circuit to implement the sustaining voltage waveform. The control logic has the zero‐switching behaviour for the driver circuit to provide better efficiency for the driving circuit. Conventionally, the VHDL programmer does not have a systematic way to program the control logic. Time delay problem of logic components in logic controller may occur under high frequency operation. With the help of the proposed Petri nets approach, the VHDL programming for the PDP driver circuit can be easier in a systematic way. Also, this paper illustrates three types of sustainers with Petri nets based FPGA controller. The basic full‐bridge and full‐voltage sustainers are used to compare the performance with the proposed half‐voltage sustainer. Details of the circuit operation are described. From the experimental results, the performance such as efficiency, luminance, and gamma curve are assessed to show the effectiveness of the proposed half‐voltage sustainer. It is believed that the proposed Petri nets based control circuit is very powerful for the practical application of the PDP sustainer circuit.

Chattering reduction of sliding mode control by low‐pass filtering the control signal
Authors: Tseng Ming‐Lei , Chen Min‐Shin
Published: February 2010

The conventional approach to reducing control signal chattering in sliding mode control is to use the boundary layer design. However, when there is high‐level measurement noise, the boundary layer design becomes ineffective in chattering reduction. This paper, therefore, proposes a new design for chattering reduction by low‐pass filtering the control signal. The new design is non‐trivial since it requires estimation of the sliding variable via a disturbance estimator. The new sliding mode control has the same performance as the boundary layer design in noise‐free environments, and outperforms the boundary layer design in noisy environments.

Task formats and ambiguity aversion
Authors: Liu Hsin‐Hsien
Published: February 2010

This paper proposes that task format (choosing or rejecting) moderates the effect of ambiguity aversion. Specifically, an ambiguous option is more attractive in a choosing task than in a rejecting task compared with a risky option. The author performed three experiments to test the propositions. In the first experiment, participants showed less ambiguity aversion when they had to choose a preferred option (risky or ambiguous) compared with when they had to reject an option they preferred less. In the second experiment with a monetary incentive, participants had to form a cash‐equivalent estimate for both a risky gamble and an ambiguous gamble in a traditional Ellsberg scenario. The ambiguous option emerged as more attractive than the risky option in the choosing task compared with the rejecting task. The third experiment showed that the participants' decision rationale mediated the effect of the task format on choice. These three experiments support the proposition that task formats moderate the effect of ambiguity aversion. On the basis of the findings, the author provides suggestions for practice and further research. Copyright © 2010 John Wiley & Sons, Ltd.
