Technology and research in a global Networked University Digital Library (NUDL)

Digital Libraries (DLs) are extremely complex information systems that support the creation, management, distribution, and preservation of complex information resources, while allowing effective and efficient interaction among the several societies that benefit from DL content and services. In this paper, we focus on our experience facing challenges of building, maintaining, and developing the Networked University Digital Library (www.nudl.org), an extension of the Networked Digital Library of Theses and Dissertations (www.ndltd.org). NUDL is a worldwide initiative that addresses making the intellectual property produced in universities more accessible, stimulating international collaboration across all disciplines. We detail technological aspects of our solutions and research activities carried out to provide powerful and enriched services for the communities served by this initiative.

Physical activity and energy expenditure in rheumatoid arthritis patients and matched controls.

OBJECTIVES: To compare daily energy expenditure between RA patients and matched controls, and to explore the relationship between daily energy expenditure or sedentariness and disease-related scores. METHODS: One hundred and ten patients with RA and 440 age- and sex-matched controls were included in this study. Energy expenditure was assessed using the validated physical activity (PA) frequency questionnaire. Disease-related scores included disease activity (DAS-28), functional status (HAQ), pain visual analogue scale (VAS) and fatigue VAS. Total energy expenditure (TEE) and the amount of energy spent in low- (TEE-low), moderate- (TEE-mod) and high-intensity (TEE-high) PAs were calculated. Sedentariness was defined as expending <10% of TEE in TEE-mod or TEE-high activities. Between-group comparisons were computed using conditional logistic regression. The effect of disease-related scores on TEE was investigated using linear regression. RESULTS: TEE was significantly lower for RA patients compared with controls [2392 kcal/day (95% CI 2295, 2490) and 2494  kcal/day (2446, 2543), respectively, P = 0.003]. A significant difference was found between groups in TEE-mod (P = 0.015), but not TEE-low (P = 0.242) and TEE-high (P = 0.146). All disease-related scores were significantly poorer in sedentary compared with active patients. TEE was inversely associated with age (P < 0.001), DAS-28 (P = 0.032) and fatigue VAS (P = 0.029), but not with HAQ and pain VAS. CONCLUSION: Daily energy expenditure is significantly lower in RA patients compared with matched controls, mainly due to less moderate-intensity PAs performed. Disease activity and fatigue are important contributing factors. These points need to be addressed if promoting PA in RA patients is a health goal. Trial registration.

Combining bone resorption markers and heel quantitative ultrasound to discriminate between fracture cases and controls.

This nested case-control analysis of a Swiss ambulatory cohort of elderly women assessed the discriminatory power of urinary markers of bone resorption and heel quantitative ultrasound for non-vertebral fractures. The tests all discriminated between cases and controls, but combining the two strategies yielded no additional relevant information. INTRODUCTION: Data are limited regarding the combination of bone resorption markers and heel quantitative bone ultrasound (QUS) in the detection of women at risk for fracture. METHODS: In a nested case-control analysis, we studied 368 women (mean age 76.2 +/- 3.2 years), 195 with low-trauma non-vertebral fractures and 173 without, matched for age, BMI, medical center, and follow-up duration, from a prospective study designed to predict fractures. Urinary total pyridinolines (PYD) and deoxypyridinolines (DPD) were measured by high performance liquid chromatography. All women underwent bone evaluations using Achilles+ and Sahara heel QUS. RESULTS: Areas under the receiver operating-characteristic curve (AUC) for discriminative models of the fracture group, with 95% confidence intervals, were 0.62 (0.56-0.68) and 0.59 (0.53-0.65) for PYD and DPD, and 0.64 (0.58-0.69) and 0.65 (0.59-0.71) for Achilles+ and Sahara QUS, respectively. The combination of resorption markers and QUS added no significant discriminatory information to either measurement alone with an AUC of 0.66 (0.60-0.71) for Achilles+ with PYD and 0.68 (0.62-0.73) for Sahara with PYD. CONCLUSIONS: Urinary bone resorption markers and QUS are equally discriminatory between non-vertebral fracture patients and controls. However, the combination of bone resorption markers and QUS is not better than either test used alone.

Canakinumab (Acz885) Relieves Pain And Controls Inflammation Rapidly In Patients With Difficult-To-Treat Gouty Arthritis : Comparison With Triamcinolone Acetonide

Background : Monosodium urate (MSU) crystals stimulate the productionof interleukin-1b (IL-1b), a potent inflammatory cytokine. Targeted IL-1b blockade with canakinumab, a fully human monoclonal anti-IL-1b antibody, is a novel treatment for gouty arthritis. Its effects on pain and inflammation in acute gouty arthritis flares were compared with triamcinolone acetonide (TA). TA has been shown to be effective in the treatment of acute gouty arthritis flares.Methods : This was an 8-week, dose-ranging, multicenter, blinded, active-controlled trial. Patients _18 to _80 years with an acute gouty arthritis flare, refractory to or contraindicated to NSAIDs and/or colchicine were randomized to one subcutaneous dose of canakinumab (10, 25, 50, 90, or 150 mg; n¼143) or one intramuscular dose of TA (40 mg; n¼57). Primary outcome was pain intensity at 72 hours post dose on VAS scale (0-100 mm). Secondary outcomes included Creactive protein (CRP), serum amyloid A (SAA), and physician's assessment of tenderness, swelling and erythema of target joint at 72 hours, 7 days, 4 and 8-weeks post dose.Results : 191/200 patients completed the study. Canakinumab showed a statistically significant dose response at 72 hours. The 150mg dose group reached superior pain relief compared to TA group starting from 24 hours as previously reported. At 72 hours post dose, 78% of canakinumab 150mg treated patients achieved _75% and 96% achieved _50% reduction in pain from baseline. In contrast, 45% and 61% of patients treated with TA achieved _75% and _50% pain reduction, respectively. Median CRP/SAA levels were normalized by Day 7 for all canakinumab doses above 10mg and remained below the upper limit of normal [(ULN): CRP 3.0 mg/L; SAA 6.7 mg/L)] for rest of the study. In TA group, median CRP levels remained above the ULN throughout the study while median SAA levels decreased below ULN only 28 days after first dose. At 72 hours post dose, canakinumab 150mg group was 3.2 (95% CI, 1.27-7.89) times more likely to have less joint tenderness and 2.7 (95% CI, 1.09-6.5) times more likely to have less joint swelling than TA group (p<0.05). At 72 hours post dose, erythema disappeared in 74.1% of patients receiving canakinumab150mg and 69.6% of patients receiving TA. At 7 days post dose, erythema was absent in 96.3% of canakinumab 150mg treated patients vs. 83.9% of patients receiving TA. The overall incidence of AEs was similar for canakinumab (41%) and triamcinolone acetonide (42%). Serious AEs (canakinumab treatment groups n¼4, TA n¼1) were not considered treatment-related by investigators. No discontinuationsdue to AEs occurred.Conclusions : Canakinumab 150mg provided superior pain relief compared to TA for acute flares in difficult-to-treat gouty arthritis patients. Canakinumab provided rapid normalization of markers of inflammation accompanied by reduction of clinical signs and symptoms of inflammation.Disclosure statement : U.A., V.M., D.R. and P.S. are shareholders and employees of Novartis Pharma AG.

CTLA-4 controls the thymic development of both conventional and regulatory T cells through modulation of the TCR repertoire.

Cytotoxic T lymphocyte-associated antigen-4 (CTLA-4; CD152) is of pivotal importance for self-tolerance, with deficiency or unfavorable polymorphisms leading to autoimmune disease. Tolerance to self-antigens is achieved through thymic deletion of highly autoreactive conventional T (Tconv) cells and generation of FoxP3(+) regulatory T (Treg) cells. The main costimulatory molecule, CD28, augments the negative selection of Tconv cells and promotes the generation of FoxP3(+) Treg cells. The role of its antagonistic homolog CTLA-4, however, remains a topic of debate. To address this topic, we investigated the thymic development of T cells in the presence and absence of CTLA-4 in a T-cell receptor (TCR) transgenic mouse model specific for the myelin basic protein peptide Ac1-9. We reveal that CTLA-4 is expressed in the corticomedullary region of the thymus. Its absence alters the response of CD4(+)CD8(-) thymocytes to self-antigen recognition, which affects the quantity of the Treg cells generated and broadens the repertoire of peripheral Tconv cells. T-cell repertoire alteration after deletion of CTLA-4 results from changes in TCR Vα and Jα segment selection as well as CDR3α composition in Tconv and Treg cells. CTLA-4, therefore, regulates the early development of self-reactive T cells in the thymus and plays a key role in central tolerance.

Is it the grain size or the characteristic pore size that controls the induced polarization relaxation time of clean sands and sandstones?

There is a wide range of evidence to suggest that permeability can be constrained through of induced polarization measurements. For clean sands and sandstones, current mechanistic models of induced polarization predict a relationship between the low-frequency time constant inferred from induced polarization measurements and the grain diameter. A number of observations do, however, disagree with this and indicate that the observed relaxation behavior is rather governed by the so-called dynamic pore radius L. To test this hypothesis, we have developed a set of new scaling relationships, which allow the relaxation time to be computed from the pore size and the permeability to be computed from both the Cole-Cole time constant and the formation factor. Moreover, these new scaling relationships can be also used to predict the dependence of the Cole-Cole time constant as a function of the water saturation under unsaturated conditions. Comparative tests of the proposed new relationships with regard to various published experimental results for saturated clean sands and sandstones as well as for partially saturated clean sandstones, do indeed confirm that the dynamic pore radius L is a much more reliable indicator of the observed relaxation behavior than grain-size-based models.

c-Myc controls the development of CD8alphaalpha TCRalphabeta intestinal intraepithelial lymphocytes from thymic precursors by regulating IL-15-dependent survival.

The murine gut epithelium contains a large population of thymus-derived intraepithelial lymphocytes (IELs), including both conventional CD4(+) and CD8alphabeta(+) T cells (expressing T-cell receptor alphabeta [TCRalphabeta]) and unconventional CD8alphaalpha(+) T cells (expressing either TCRalphabeta or TCRgammadelta). Whereas conventional IELs are widely accepted to arise from recirculation of activated CD4(+) and CD8alphabeta(+) T cells from the secondary lymphoid organs to the gut, the origin and developmental pathway of unconventional CD8alphaalpha IELs remain controversial. We show here that CD4-Cre-mediated inactivation of c-Myc, a broadly expressed transcription factor with a wide range of biologic activities, selectively impairs the development of CD8alphaalpha TCRalphabeta IELs. In the absence of c-Myc, CD4(-) CD8(-) TCRalphabeta(+) thymic precursors of CD8alphaalpha TCRalphabeta IELs are present but fail to develop on adoptive transfer in immunoincompetent hosts. Residual c-Myc-deficient CD8alphaalpha TCRalphabeta IEL display reduced proliferation and increased apoptosis, which correlate with significantly decreased expression of interleukin-15 receptor subunits and lower levels of the antiapoptotic protein Bcl-2. Transgenic overexpression of human BCL-2 resulted in a pronounced rescue of CD8alphaalpha TCRalphabeta IEL in c-Myc-deficient mice. Taken together, our data support a model in which c-Myc controls the development of CD8alphaalpha TCRalphabeta IELs from thymic precursors by regulating interleukin-15 receptor expression and consequently Bcl-2-dependent survival.
