    For the histopathological classification of the severity of osteoarthritic lesions of cartilage, the Mankin score is frequently used. A necessary constraint on the validity of this scoring system is the consistency with which cartilage lesions are classified. The intra- and interobserver agreement

  4. Janybek Khan and Prince Liubartas-Dmitry

    Full Text Available This study focuses on the relations between the Volyn principality of Liubartas-Dmitry and the Ulus of Jochi under the rule of Janybek Khan. Liubartas-Dmitry ascended the throne of the Eastern Volyn largely due to the will of Uzbek Khan. The Land of Berestia together with the Eastern Volyn was the Liubartas’ appanage land in Volyn. As Boleslaw-Yuri II, Liubartas-Dmitry was compelled to pay tribute to the Tatars. During the War of the Galicia-Volyn legacy, Liubartas acted as a vassal of the Ulus of Jochi and ally of Uzbek Khan. Liubartas’ relations with Janybek Khan were fundamentally different from his previous relations with Uzbek Khan. Casimir III enjoyed greater sympathy of the Golden Horde khan due to the payment of tribute. Except for the campaign of 1351–1352, Janybek was hostile towards Lithuania. Only the common hostility of the Poles and Hungarians towards the Volyn and Podolia forced the khan of Ulus of Jochi to intervene on the side of the Lithuanians. For Janibek the western vector of his foreign policy was not a priority. He could accept the loss of a tribute from several Slavic principalities in exchange for success on other fronts, more profitable in terms of the spoils of war. Unlike the Koriatoviches and Olelkoviches, the Gediminoviches of Volyn were more peacefully disposed towards the Tatars since during the “Great Disorder” their land-holdings did not increase at the expense of Jochid possessions.

  14. Modeling sub-sea permafrost in the East Siberian Arctic Shelf: the Dmitry Laptev Strait

    Nicolsky, D; Shakhova, N

    2010-01-01

    The present state of sub-sea permafrost modeling does not agree with certain observational data on the permafrost state within the East Siberian Arctic Shelf. This suggests a need to consider other mechanisms of permafrost destabilization after the recent ocean transgression. We propose development of open taliks wherever thaw lakes and river paleo-valleys were submerged shelf-wide as a possible mechanism for the degradation of sub-sea permafrost. To test the hypothesis we performed numerical modeling of permafrost dynamics in the Dmitry Laptev Strait area. We achieved sufficient agreement with the observed distribution of thawed and frozen layers to suggest that the proposed mechanism of permafrost destabilization is plausible.

  15. Mirrors in Russian Decadent and Symbolist Prose: Valery Briusov and Dmitry Merezhkovsky

    Directory of Open Access Journals (Sweden)

    Kirsten Lodge

    2010-06-01

    Full Text Available Examining mirror imagery in the prose works “In the Mirror” by Valery Briusov and The Resurrected Gods: Leonardo da Vinci by Dmitry Merezhkovsky, both published in 1902, this article situates the Russian Decadent and Symbolist associations of the mirror in the pan-European literary and philosophical context. The mirror constitutes the threshold of manifold oppositions, including life and art, life and death, and reality and dream or imagination. It is a realm of alternative reality, magical and seductive, as in Briusov’s story, or potentially both demonic and divine, as in Merezhkovsky’s novel. In accordance with the Romantic tradition as well as Decadent and Symbolist iconography, mirror imagery in these two works is inseparable from questions of the nature of art and the power of artistic creation.

  16. Everyday Language Used by Dmitry Medvedev, the President of Russian Federation, as an Image Strategy Too

    2011-09-01

    Full Text Available This article is devoted to the analysis of the most frequent use of everyday language used in the speeches and statements of President Dmitry Medvedev. From the research it becomes clear that the main target is the Russian audience. However, some statements of this type aim also to influence foreign listeners and readers. At the same time, one purpose is to influence internal recipients differently from external recipients. This means that everyday language plays a different role in domestic communication from that in international communication and needs to be analyzed separately.

  18. AUTOBIOGRAPHY VS PHOTOGRAPHY AND MEMOIR VS CARICATURE AS FORMS OF PRESERVING THE AUTHOR’S MEMORY (DMITRY S. MEREZHKOVSKY

    Directory of Open Access Journals (Sweden)

    Аlexey А. Kholikov

    2017-03-01

    Full Text Available The essay focuses on visual images as one of the means of the writer’s reception on the example of such forms of preserving memory about Dmitry S. Merezhkovsky as autobiography and photography, on the one hand, and memoir and caricature, on the other. Photographic image comes close to autobiography in the following aspects. First, there is a functional affinity between these two forms, a verbal one and a visual one: both share the desire for authenticity. At the same time, photography as autobiography has not just documentary potential: photographic image is equally capable of reproducing and of reducing or distorting reality. Finally, photography (and this is its another affinity with a documentary genre presents not only individual and personal but also cultural and historical interest. Between caricature and memoir — another pair of media preserving verbal and visual memory about the writer — there are overlaps as well. These “spaces” of memory have bigger potential for interpretation of the image than photography or autobiography. I prove this point by analyzing specific details that were emphasized by caricatures and memoirs of Merezhkovsky. At the same time, I argue that caricature as a visual “space” of memory is not self-sustained the same way photography and portrait are. The other aspect the essay is concerned with the elements of the memory about the writer that remain untranslatable into visual language. Methodologically, the essay relies on the works by N.I. Zhinkin, Y.N. Tyanyanov, Y.M. Lotman, R. Barthes, and S. Sontag.

    To evaluate the usefulness of quantitative parameters obtained by optical coherence tomography (OCT) and magnetic resonance imaging (MRI) in the comprehensive assessment of human articular cartilage degeneration. Human osteochondral samples of variable degeneration (n = 45) were obtained from total knee replacements and assessed by MRI sequences measuring T1, T1ρ, T2 and T2* relaxivity and by OCT-based quantification of irregularity (OII, optical irregularity index), homogeneity (OHI, optical homogeneity index) and attenuation (OAI, optical attenuation index). Samples were also assessed macroscopically (Outerbridge classification) and histologically (Mankin classification) as grade-0 (Mankin scores 0-4)/grade-I (scores 5-8)/grade-II (scores 9-10)/grade-III (score 11-14). After data normalisation, differences between Mankin grades and correlations between imaging parameters were assessed using ANOVA and Tukey's post-hoc test and Spearman's correlation coefficients, respectively. Sensitivities and specificities in the detection of Mankin grade-0 were calculated. Significant degeneration-related increases were found for T2 and OII and decreases for OAI, while T1, T1ρ, T2* or OHI did not reveal significant changes in relation to degeneration. A number of significant correlations between imaging parameters and histological (sub)scores were found, in particular for T2 and OII. Sensitivities and specificities in the detection of Mankin grade-0 were highest for OHI/T1 and OII/T1ρ, respectively. Quantitative OCT and MRI techniques seem to complement each other in the comprehensive assessment of cartilage degeneration. Sufficiently large structural and compositional changes in the extracellular matrix may thus be parameterized and quantified, while the detection of early degeneration remains challenging. (orig.)

    Objective: To validate gradient-echo three-dimensional (3D) delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC) by means of histological analyses in the assessment of hip joint cartilage. Materials and methods: Twenty-one femoral head specimens collected from 21 patients (7 males, 14 females, mean age: 60.9 ± 9.6 years; range: 37.6–77.3 years), who underwent total hip replacement for symptomatic hip joint osteoarthritis, underwent MRI and histological assessment. A region of 2 cm{sup 2} at the weight-bearing area was marked with four pins to enable multi-planar MRI reformatting to be matched with histological sections. MRI was performed at 3 T with a 3D double-echo steady-state (DESS) sequence for morphological cartilage assessment and 3D Volumetric Interpolated Breathhold Examination (VIBE) for T1{sub Gd} mapping. Histological sections were evaluated according to the Mankin score system. Total Mankin score, grade of toluidine staining (sensitive for glycosaminoglycan content) and a modified Mankin score classification system with four sub-groups of cartilage damage were correlated with MRI data. Results: Spearman's rho correlation analyses revealed a statistically significant correlation between T1{sub Gd} mapping and histological analyses in all categories including total Mankin score (r = −0.658, p-value ≤ 0.001), toluidine staining (r = −0.802, p-value < 0.001) and modified Mankin score (r = −0.716, p-value < 0.001). The correlation between morphological MRI and histological cartilage assessment was statistically significant but inferior to the biochemical cartilage MRI (r-values ranging from −0.411 to 0.525, p-values < 0.001). Conclusions: Gradient-echo dGEMRIC is reliable while offering the unique features of high image resolution and 3D biochemically sensitive MRI for the assessment of early cartilage degeneration.

    Osteoarthritis (OA) may result from intrinsic inflammation related to metabolic disturbance. Obesity-associated inflammation is triggered by lipopolysaccharide (LPS) derived from the gut microbiota. However, the relationship between gut microbiota, LPS, inflammation, and OA remain unclear. To evaluate the associations between gut microbiota, systemic LPS levels, serum and local inflammatory profiles, and joint damage in a high fat/high sucrose diet induced obese rat model. 32 rats were randomized to a high fat/high sucrose diet (diet-induced obese (DIO), 40% fat, 45% sucrose, n = 21) or chow diet group (12% fat, 3.7% sucrose n = 11) for 28 weeks. After a 12-week obesity induction period, DIO animals were stratified into Obesity Prone (DIO-P, top 33% by change in body mass, n = 7), and Obesity Resistant groups (DIO-R, bottom 33%, n = 7). At sacrifice, joints were scored using a Modified Mankin Criteria. Blood and synovial fluid analytes, serum LPS, and fecal gut microbiota were analyzed. DIO animals had greater Modified Mankin scores than chow animals (P = 0.002). There was a significant relationship (r = 0.604, p = 0.001) between body fat, but not body mass, and Modified Mankin score. Eighteen synovial fluid and four serum analytes were increased in DIO animals. DIO serum LPS levels were increased compared to chow (P = 0.031). Together, Lactobacillus species (spp.) and Methanobrevibacter spp. abundance had a strong predictive relationship with Modified Mankin Score (r(2) = 0.5, P gut microbiota and adiposity-derived inflammation and metabolic OA warrants further investigation.

    To evaluate T2* values in various histological severities of osteoarthritis (OA). Magnetic resonance imaging (MRI) and T2* mapping including a three-dimensional (3D) double-echo steady-state (DESS) sequence for morphological cartilage assessment and a 3D multiecho data image combination (MEDIC) sequence for T2* mapping were conducted in 21 human femoral head specimens with varying severities of OA. Subsequently, histological assessment was undertaken in all specimens to correlate the observations of T2* mapping with histological analyses. According to the Mankin score, four grades of histological changes were determined: grade 0 (Mankin scores of 0-4), grade I (scores of 5-8), grade II (scores of 9-10), and grade III (scores of 11-14). For reliability assessment, cartilage T2* measurements were repeated after 4 weeks in 10 randomly selected femoral head specimens. T2* values decreased significantly with increasing cartilage degeneration (total P-values fair correlation between T2* values and Mankin score (correlation coefficient = -0.362) that was statistically significant (P-value advantages of the T2* mapping technique with no need for contrast medium, high image resolution and ability to perform 3D biochemically sensitive imaging, T2* mapping may be a strong addition to the currently evolving era of cartilage biochemical imaging.

    To evaluate the therapeutic effects of domestic chicken collagen type II (CCII) on rat osteoarthritis (OA) and analyze concomitant changes in the level of Matrix metalloproteinase (MMP)-13, MMP-9, Cathepsin K and their mRNA as well as the tissue inhibitor of matrix metalloproteinase (TIMP)-1 mRNA in articular cartilage of osteoarthritic rats. Osteoarthritis models were surgically induced. Morphology of articular cartilage was done by haematoxylin and eosin staining and Mankin score was calculated, immunohistochemistry of MMP-13, MMP-9 and Cathepsin K was done by ABC method while the mRNA level for MMP-13, MMP-9, cathepsin K as well as TIMP-1 was evaluated by RT-PCR method. Oral administration of CCII reduced the morphological changes of osteoarthritic cartilage (shown by Mankin score), decreased levels of MMP-13, MMP-9, cathepsin K as well as their mRNA in articular cartilage from osteoarthritic rats while it exhibited no effect on TIMP-1 mRNA. Oral CCII reduced articular cartilage degradation of osteoarthritic rats and may probably be a potent drug candidate for OA treatment.

    This study was designed to investigate the anti-nociceptive effect of Morus alba stem extract as well as its cartilage protective effect in the anterior cruciate ligament transection (ACLT)-induced rat model of osteoarthritis (OA). The anti-nociceptive effect of this plant extract was determined by measuring hind limb weight bearing, while the severity of cartilage damage to the knee joints was evaluated using the modified Mankin grading system. Oral administration of M. alba stem extract (56 and 560 mg/kg) significantly attenuated joint pain as indicated by a significant (p alba stem extract at 56 and 560 mg/kg when compared to those of the vehicle-treated OA-induced group. In addition, a significant improvement in the Mankin score was also observed in rats treated with 560 mg/kg M. alba stem extract, which was in agreement with its pain-relieving effect. The results showed that M. alba stem extract exhibited an anti-nociceptive effect as well as cartilage protection in the ACLT-induced rat model of OA, supporting its potential use as a therapeutic treatment for OA. © 2016 S.

    2015-12-01

    Full Text Available This paper is devoted to the history and controversies surrounding the outstanding representative of Russian medieval literature from the late 14th century, the famous Zadonshchina. This work glorifies the military victory of the united forces of the Russian troops, led by Grand Prince Dmitry Donskoy, over the Tatar army on 8 September 1380, at Kulikovo Field near the Don River. This article presents arguments in favor of a Ryazan origin of the Zadonshchina text; furthermore, the article offers an explanation of the presence in the text of two “protagonists,” Grand Prince Dmitry Ivanovich and his cousin, Vladimir Andreyevich the Bold, Prince of Serpukhov. The joint rule of the “brothers” was a result of deaths caused by the plague in the Moscow ruling house, which took the dynasty to the brink of extinction. This feature of the political situation is reflected in the Zadonshchina text.

    Meniscus injuries and resulting meniscectomies lead to joint deterioration, causing pain, discomfort, and instability. Tissue-engineered devices to replace the meniscus have not shown consistent success with regard to function, mechanical integrity, or protection of cartilage. To evaluate a novel resorbable polymer fiber-reinforced meniscus reconstruction scaffold in an ovine model for 52 weeks and assess its integrity, tensile and compressive mechanics, cell phenotypes, matrix organization and content, and protection of the articular cartilage surfaces. Controlled laboratory study. Eight skeletally mature ewes were implanted with the fiber-reinforced scaffold after total meniscectomy, and 2 additional animals had untreated total meniscectomies. Animals were sacrificed at 52 weeks, and the explants and articular surfaces were analyzed macroscopically. Explants were characterized by ultimate tensile testing, confined compression creep testing, and biochemical, histological, and immunohistochemical analyses. Cartilage damage was characterized using the Mankin score on histologic slides from both the femur and tibia. One sheep was removed from the study because of a torn extensor tendon; the remaining 7 explants remained fully intact and incorporated into the bone tunnels. All explants exhibited functional tensile loads, tensile stiffnesses, and compressive moduli. Fibrocartilagenous repair with both types 1 and 2 collagen were observed, with areas of matrix organization and biochemical content similar to native tissue. Narrowing in the body region was observed in 5 of 7 explants. Mankin scores showed less cartilage damage in the explant group (femoral condyle: 3.43 ± 0.79, tibial plateau: 3.50 ± 1.63) than in the meniscectomy group (femoral condyle: 8.50 ± 3.54, tibial plateau: 6.75 ± 2.47) and were comparable with Mankin scores at the previously reported 16- and 32-week time points.

    Objective The objective of this study was to determine whether intra-articular injections of tenascin-C (TNC) could prevent cartilage damage in murine models of osteoarthritis (OA). Design Fluorescently labeled TNC was injected into knee joints and its distribution was examined at 1 day, 4 days, 1 week, 2 weeks, and 4 weeks postinjection. To investigate the effects of TNC on cartilage degeneration after surgery to knee joints, articular spaces were filled with 100 μg/mL (group I), 10 μg/mL (group II) of TNC solution, or control (group III). TNC solution of 10 μg/mL was additionally injected twice after 3 weeks (group IV) or weekly after 1 week, 2 weeks, and 3 weeks (group V). Joint tissues were histologically assessed using the Mankin score and the modified Chambers system at 2 to 8 weeks after surgery. Results Exogenous TNC was maintained in the cartilage and synovium for 1 week after administration. Histological scores in groups I and II were better than scores in group III at 4 and 6 weeks, but progressive cartilage damage was seen in all groups 8 weeks postoperatively. Sequential TNC injections (groups IV and V) showed significantly better Mankin score than single injection (group II) at 8 weeks. Conclusion TNC administered exogenously remained in the cartilage of knee joints for 1 week, and could decelerate articular cartilage degeneration in murine models of OA. We also showed that sequential administration of TNC was more effective than a single injection. TNC could be an important molecule for prevention of articular cartilage damage.

    To assess the electromechanical properties of human knee articular cartilage with compression-induced streaming potentials for reliability among users and correlation with macroscopic and histological evaluation tools and sulfated glycosaminoglycan (sGAG) content. Streaming potentials are induced in cartilage in response to loading when mobile positive ions in the interstitial fluid temporarily move away from negatively charged proteoglycans. Streaming potential integrals (SPIs) were measured with an indentation probe on femoral condyles of 10 human knee specimens according to a standardized location scheme. Interobserver reliability was measured using an interclass correlation coefficient (ICC). The learning curves of 3 observers were evaluated by regression analysis. At each SPI measurement location the degradation level of the tissue was determined by means of the International Cartilage Repair Society (ICRS) score, Mankin score, and sGAG content. The computed ICC was 0.77 (0.70-0.83) indicating good to excellent linear agreement of SPI values among the 3 users. A significant positive linear correlation of the learning index values was observed for 2 of the 3 users. Statistically significant negative correlations between SPI and both ICRS and Mankin scores were observed (r = 0.502, P < 0.001, and r = 0.255, P = 0.02, respectively). No correlation was observed between SPI and sGAG content (r = 0.004, P = 0.973). SPI values may be used as a quantitative means of cartilage evaluation with sufficient reliability among users. Due to the significant learning curve, adequate training should be absolved before routine use of the technique.

    Objective The objectives of this study were to 1) determine the correlation between osteoarthritis (OA) and Ihh expression, and 2) establish the effects of Ihh on expression of markers of chondrocyte hypertrophy and MMP-13 in human OA cartilage. Design OA cartilage and synovial fluid samples were obtained during total knee arthroplasty. Normal cartilage samples were obtained from intra-articular tumor resections, and normal synovial fluid samples were obtained from healthy volunteers and the contralateral uninjured knee of patients undergoing anterior cruciate ligament reconstruction. OA was graded using the Mankin score. Expression of Ihh in synovial fluid was determined by western blot. Ihh, type X collagen and MMP-13 mRNA were determined by real time PCR. Protein expression of type X collagen and MMP-13 in cartilage samples were analyzed with immunohistochemistry. Chondrocyte size was measured using image analysis. Results Ihh expression was increased 2.6 fold in OA cartilage and 37% in OA synovial fluid when compared to normal control samples. Increased expression of Ihh was associated with the severity of OA and expression of markers of chondrocyte hypertrophy: type X collagen and MMP-13, and chondocyte size. Chondrocytes were more spherical with increasing severity of OA. There was a significant correlation between Mankin score and cell size (r2= 0.80) and Ihh intensity (r2 = 0.89). Exogenous Ihh induced a 6.8 fold increase of type X collagen and 2.8 fold increase of MMP-13 mRNA expression in cultured chondrocytes. Conversely, knockdown of Ihh by siRNA and Hh inhibitor Cyclopamine had the opposite effect. Conclusions Ihh expression correlates with OA progression and changes in chondrocyte morphology and gene expression consistent with chondrocyte hypertrophy and cartilage degradation seen in OA cartilage. Thus, Ihh may be a potential therapeutic target to prevent OA progression. PMID:22469853

    To investigate the disease modifying effects of cathepsin K (CatK) inhibitor L-006235 compared to alendronate (ALN) in two preclinical models of osteoarthritis (OA). Skeletally mature rabbits underwent sham or anterior cruciate ligament transection (ACLT)-surgery and were treated with L-006235 (L-235, 10 mg/kg or 50 mg/kg, p.o., daily) or ALN (0.6 mg/kg, s.c., weekly) for 8-weeks. ACLT joint instability was also induced in CatK(-/-) versus wild type (wt) mice and treated for 16-weeks. Changes in cartilage degeneration, subchondral bone volume and osteophyte area were determined by histology and μ-CT. Collagen type I helical peptide (HP-I), a bone resorption marker and collagen type II C-telopeptide (CTX-II), a cartilage degradation marker were measured. L-235 (50 mg/kg) and ALN treatment resulted in significant chondroprotective effects, reducing CTX-II by 60% and the histological Mankin score for cartilage damage by 46% in the ACLT-rabbits. Both doses of L-235 were more potent than ALN in protecting against focal subchondral bone loss, and reducing HP-I by 70% compared to vehicle. L-235 (50 mg/kg) and ALN significantly reduced osteophyte formation in histomorphometric analysis by 55%. The Mankin score in ACLT-CatK(-/-) mice was ~2.5-fold lower than the ACLT-wt mice and was not different from sham-CatK(-/-). Osteophyte development was not different among the groups. Inhibition of CatK provides significant benefits in ACLT-model of OA, including: 1) protection of subchondral bone integrity, 2) protection against cartilage degradation and 3) reduced osteophytosis. Preclinical evidence supports the role of CatK as a potential therapeutic target for the treatment of OA. Copyright © 2012 Elsevier Inc. All rights reserved.

    While intra-articular injection of sinomenine hydrochloride has a therapeutic effect on osteoarthritis, it has a short half-life, and is thermolabile and photolabile. The aim of this research was to evaluate the sustained-release of sinomenine hydrochloride from an injectable sinomenine hydrochloride and sodium hyaluronate compound (CSSSI) and its therapeutic effect in a rabbit model of osteoarthritis following intra-articular injection. An injectable compound consisting of 1% sodium hyaluronate and 2.5% sinomenine hydrochloride was prepared and kept as the experiment group, and 2.5% sinomenine hydrochloride was prepared and kept as the control group. The cumulative mass release was measured at different time points in each group in vitro. Sixty-five male Zelanian rabbits were randomly divided into five groups: 15 (30 knees) each for the control, sodium hyaluronate, sinomenine hydrochloride, and CSSSI groups respectively, and five (10 knees) for the modeling group. Papain was injected into both knees of each rabbit for model establishment. Subsequently, 0.2 ml of the corresponding drugs was injected into the articular cavities of the remaining experiment groups, while the control group was treated with 0.2 ml normal saline. All groups were treated once a week for 4 weeks. Seven days after the last treatment, knees were anatomized to perform pathological observations and Mankin's evaluation of the synovium. Four groups were compared using the SPSS 13.0 software package. In the in vitro sustained-release experiments, 90% of the drug was released in the experiment group 360 minutes following the injection. Comparison of the Mankin's evaluations of the four groups illustrated statistical discrepancies (P sodium hyaluronate/sinomenine hydrochloride groups, statistical significance was uniformly obtained. Moreover, sodium hyaluronate and sinomenine hydrochloride treatments showed significant improvement over the modeling control (P sodium hyaluronate vs. sinomenine

    The purpose of this study was to evaluate various types of meniscus scaffolds that mimic the meniscus structure, and to establish a novel cell-free meniscus scaffold with polyglycolic acid or poly-l-lactic acid. Four types of scaffolds were implanted into Japanese white rabbits: poly-l-lactic acid sponge poly-l-lactic acid, PGA-coated PLLA sponge, PGA lamination, and film-coated PGA lamination. Samples were harvested at 8 and 12 weeks after implantation, and a compression stress test was performed. The meniscus size and Ishida scores were evaluated for regenerated tissue. Immunohistochemistry was analyzed by anti-type I, II and X collagen antibodies to investigate the structure of the regenerated tissue, and by anti-iNOS antibody to investigate the inflammatory tissue of the meniscus. The cell nuclei of lymphocytes and foreign body multinucleated giant cells were counted in hematoxylin and eosin staining. Modified Mankin scores for cartilage degeneration were used for assessment after Safranin-O/Fast Green staining. The biomechanical test showed that l- and film-coated PGA lamination exhibited greater strength than s- and PGA-coated PLLA sponge. At 12 weeks, the size of meniscus and the Ishida score in implanted film-coated PGA lamination were improved significantly compared with the defect groups. The type II collagen staining intensity in the PGA lamination lamination is significantly higher than the defect at eight weeks. The staining intensity of iNOS and number of lymphocytes significantly increased in sponge poly-l-lactic acid at eight weeks, and increased in p-PLLA at 12 weeks. Foreign body multinucleated giant cells in implantation groups appeared, especially at eight weeks. The Mankin score for film-coated PGA lamination was significantly lower than for the defect at 12 weeks. Novel meniscal scaffolds especially PGA should possess not only biological but also biomechanical functions. In conclusions, film-coated PGA lamination was the beneficial property

    It remains to be shown whether OA shares molecular similarities between different joints in humans. This study provides evidence for similarities in cartilage molecular damage in osteoarthritic (OA) joints. Articular cartilage from osteoarthritic hip joints were analysed and compared to non-OA controls regarding collagen, glycosaminoglycan and water content. Femoral heads from 16 osteoarthritic (OA) and 20 reference patients were obtained from hip replacement surgery due to OA and femoral neck fracture, respectively. Cartilage histological changes were assessed by Mankin grading and denatured collagen type II immunostaining and cartilage was extracted by α-chymotrypsin. Hydroxyproline and Alcian blue binding assays were used to measure collagen and glycosaminoglycan (GAG) content, respectively. Mankin and immunohistology scores were significantly higher in hip OA samples than in reference samples. Cartilage water content was 6% higher in OA samples than in references. 2.5 times more collagen was extracted from OA than from reference samples. There was a positive association between water content and percentage of extractable collagen pool (ECP) in both groups. The amounts of collagen per wet and dry weights did not differ statistically between OA and reference cartilage. % Extractable collagen was not related to collagen per dry weight in either group. However when collagen was expressed by wet weight there was a negative correlation between % extractable and collagen in OA cartilage. The amount of GAG per wet weight was similar in both groups but the amount of GAG per dry weight was higher in OA samples compared to reference samples, which suggests a capacity for GAG biosynthesis in hip OA cartilage. Neither of the studied parameters was related to age in either group. Increased collagen extractability and water content in human hip cartilage is associated with OA pathology and can be observed at early stages of the degenerative hip OA process. Our results

    2012-01-01

    ABSTRACT: INTRODUCTION: Telomere shortening is associated with a number of common age-related diseases. A role of telomere shortening in osteoarthritis (OA) has been suggested, mainly based on the assessment of mean telomere length in ex vivo expanded chondrocytes. We addressed this role directly...... in vivo by using a newly developed assay, which measures specifically the load of ultra-short single telomeres (below 1,500 base pairs), that is, the telomere subpopulation believed to promote cellular senescence. METHODS: Samples were obtained from human OA knees at two distances from the central lesion...... site. Each sample was split into three: one was used for quantification of ultra-short single telomeres through the Universal single telomere length assay (STELA), one for histological Mankin grading of OA, and one for mean telomere length measurement through quantitative fluorescence in situ...

    Objectives: Implementation of an experimental model to compare cartilage MR imaging by means of histological analyses. Material and methods: MRI was obtained from 4 patients expecting total knee replacement at 1.5 and/or 3 T prior surgery. The timeframe between pre-op MRI and knee replacement was within two days. Resected cartilage-bone samples were tagged with Ethi-pins to reproduce the histological cutting course. Pre-operative scanning at 1.5 T included following parameters for fast low angle shot (FLASH: TR/TE/FA = 33 ms/6 ms/30 deg., BW = 110 kHz, 120 mm x 120 mm FOV, 256 x 256 matrix, 0.65 mm slice-thickness) and double echo steady state (DESS: TR/TE/FA = 23.7 ms/6.9 ms/40 deg., BW = 130 kHz, 120 x 120 mm FOV, 256 x 256 matrix, 0.65 mm slice-thickness). At 3 T, scan parameters were: FLASH (TR/TE/FA = 12.2 ms/5.1 ms/10 deg., BW = 130 kHz, 170 x 170 mm FOV, 320 x 320, 0.5 mm slice-thickness) and DESS (TR/TE/FA = 15.6 ms/4.5 ms/25 deg., BW = 200 kHz, 135 mm x 150 mm FOV, 288 x 320 matrix, 0.5 mm slice-thickness). Imaging of the specimens was done the same day at 1.5 T. MRI (Noyes) and histological (Mankin) score scales were correlated using the paired t-test. Sensitivity and specificity for the detection of different grades of cartilage degeneration were assessed. Inter-reader and intra-reader reliability was determined using Kappa analysis. Results: Low correlation (sensitivity, specificity) was found for both sequences in normal to mild Mankin grades. Only moderate to severe changes were diagnosed with higher significance and specificity. The use of higher field-strengths was advantageous for both protocols with sensitivity values ranging from 13.6% to 93.3% (FLASH) and 20.5% to 96.2% (DESS). Kappa values ranged from 0.488 to 0.944. Conclusions: Correlating MR images with continuous histological slices was feasible by using three-dimensional imaging, multi-planar-reformat and marker pins. The capability of diagnosing early cartilage changes with high accuracy

    Articular cartilage degeneration has been evaluated by magnetic resonance imaging (MRI). However, this method has several problems, including its time-consuming nature and the requirement of a high magnetic field or specialized hardware. The purpose of this study was to sequentially assess early degenerative changes in rabbit knee articular cartilage using MRI with a new double-contrast agent. We induced osteoarthritis (OA) in the right knee of rabbits by anterior cruciate ligament transection and partial medial meniscectomy. Proton density-weighted images and T 2 -calculated images were obtained before and after contrast agent injection into the knee. The signal intensity ratio (SIR) values on the proton density-weighted images were calculated by dividing the signal intensity of the articular cartilage by that of joint fluid. Six rabbits were examined using MRI at 2 (designated 2-w OA) and 4 weeks (4-w OA) after the operation. Histological examination was performed 4 weeks after the operation. One rabbit was histologically examined 2 weeks after the operation. The control consisted of six rabbits that were not subjected to the operation. The SIR values, T 2 values and the thicknesses of the cartilage of the 2-w OA, 4-w OA and the control before and after contrast agent injection were analyzed. The Mankin score and OARSI (Osteoarthritis Research Society International) score were used for the histological evaluation. Significant differences in the SIR and T 2 values of the medial and lateral condyles of the femur were found between the control and the 4-w OA only after contrast agent injection. No significant differences were found in the SIR and T 2 values before contrast agent injection between the control, the 2-w OA and 4-w OA. The thickness of the articular cartilage revealed no significant differences. In the histological assessment, the Mankin score and OARSI score sequentially increased from the control to the 4-w OA. We evaluated the SIR and T 2 values

    Full Text Available Abstract Background Osteoarthritis (OA is a progressive and debilitating disease that often develops from a focal lesion and may take years to clinically manifest to a complete loss of joint structure and function. Currently, there is not a cure for OA, but early diagnosis and initiation of treatment may dramatically improve the prognosis and quality of life for affected individuals. This study was designed to determine the feasibility of analyzing changes in gene expression of articular cartilage using the Pond-Nuki model two weeks after ACL-transection in dogs, and to characterize the changes observed at this time point. Methods The ACL of four dogs was completely transected arthroscopically, and the contralateral limb was used as the non-operated control. After two weeks the dogs were euthanatized and tissues harvested from the tibial plateau and femoral condyles of both limbs. Two dogs were used for histologic analysis and Mankin scoring. From the other two dogs the surface of the femoral condyle and tibial plateau were divided into four regions each, and tissues were harvested from each region for biochemical (GAG and HP and gene expression analysis. Significant changes in gene expression were determined using REST-XL, and Mann-Whitney rank sum test was used to analyze biochemical data. Significance was set at (p Results Significant differences were not observed between ACL-X and control limbs for Mankin scores or GAG and HP tissue content. Further, damage to the tissue was not observed grossly by India ink staining. However, significant changes in gene expression were observed between ACL-X and control tissues from each region analyzed, and indicate that a unique regional gene expression profile for impending ACL-X induced joint pathology may be identified in future studies. Conclusion The data obtained from this study lend credence to the research approach and model for the characterization of OA, and the identification and validation of

    Meniscus injuries in the United States result in an estimated 850,000 surgical procedures each year. Although meniscectomies are the most commonly performed orthopaedic surgery, little advancement has been made in meniscus replacement and regeneration, and there is currently no total meniscus replacement device approved by the Food and Drug Administration. A novel fiber-reinforced meniscus scaffold can be used as a functional total meniscus replacement. Controlled laboratory study. A tyrosine-derived, polymer fiber-reinforced collagen sponge meniscus scaffold was evaluated mechanically (tensile and compressive testing) and histologically after 16 and 32 weeks of implantation in an ovine total meniscectomy model (N = 20; 16 implants plus 4 meniscectomies, divided equally over the 2 time periods). The extent of cartilage damage was also measured on tibial plateaus by use of toluidine blue surface staining and on femoral condyles by use of Mankin scores on histological slides. Scaffolds induced formation of neomeniscus tissue that remained intact and functional, with breaking loads approximating 250 N at both 16 and 32 weeks compared with 552 N for native menisci. Tensile stiffness values (99 and 74 N/mm at 16 and 32 weeks, respectively) were also comparable with those of the native meniscus (147 N/mm). The compressive modulus of the neomeniscus tissue (0.33 MPa at both 16 and 32 weeks) was significantly increased compared with unimplanted (time 0) scaffolds (0.15 MPa). There was histological evidence of extensive tissue ingrowth and extracellular matrix deposition, with immunohistochemical evidence of types I and II collagen. Based on significantly decreased surface damage scores as well as Mankin scores, the scaffold implants provided greater protection of articular cartilage compared with the untreated total meniscectomy. This novel fiber-reinforced meniscus scaffold can act as a functional meniscus replacement, with mechanical properties similar to those of the

    The meniscus injury and post-traumatic knee osteoarthritis (PTOA) following anterior cruciate ligament (ACL) lesions often cause great burdens to patients. Ghrelin, a recently identified 28-amino-acid peptide, has been shown to inhibit inflammation and perform as a growth factor for chondrocyte. This study was aimed at investigating ghrelin concentration in synovial fluid and its association with the degree of meniscus injury, articular degeneration, and clinical severity in patients suffering from anterior cruciate ligament (ACL) deficiency. 61 ACL deficiency patients admitted to our hospital were drafted in the current study. The Noyes scale and Mankin scores were used to assess articular cartilage damage arthroscopically and histopathologically, respectively. The Lysholm scores and International Knee Documentation Committee (IKDC) subjective scores were utilized to evaluate the clinical severity. The radiological severity of meniscus injury was assessed by MR imaging. Serum and synovial fluid ghrelin levels were determined using enzyme linked immunosorbent assay (ELISA). The cartilage degradation markers collagen type II C-telopeptide (CTX-II) and cartilage oligomeric matrix protein (COMP) in addition to inflammatory markers interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) were also examined. Receiver operating characteristic (ROC) curve was performed and the area under curve (AUC) was calculated to assess the diagnostic value of ghrelin levels for the prediction of the MRI grading for meniscus injury by comparing with other biomarkers. SF ghrelin levels were positively related to Lysholm and IKDC scores. PTOA patients with grade 3 showed significantly decreased levels of ghrelin in SF compared with those with grade 2. The ghrelin levels in SF were negatively related to MRI signal grades for meniscus injury. SF ghrelin levels were also inversely associated with Noyes scale and Mankin scores, and levels of inflammation markers IL-6, TNF-α, and

    Full Text Available Abstract Background It remains to be shown whether OA shares molecular similarities between different joints in humans. This study provides evidence for similarities in cartilage molecular damage in osteoarthritic (OA joints. Methods Articular cartilage from osteoarthritic hip joints were analysed and compared to non-OA controls regarding collagen, glycosaminoglycan and water content. Femoral heads from 16 osteoarthritic (OA and 20 reference patients were obtained from hip replacement surgery due to OA and femoral neck fracture, respectively. Cartilage histological changes were assessed by Mankin grading and denatured collagen type II immunostaining and cartilage was extracted by α-chymotrypsin. Hydroxyproline and Alcian blue binding assays were used to measure collagen and glycosaminoglycan (GAG content, respectively. Results Mankin and immunohistology scores were significantly higher in hip OA samples than in reference samples. Cartilage water content was 6% higher in OA samples than in references. 2.5 times more collagen was extracted from OA than from reference samples. There was a positive association between water content and percentage of extractable collagen pool (ECP in both groups. The amounts of collagen per wet and dry weights did not differ statistically between OA and reference cartilage. % Extractable collagen was not related to collagen per dry weight in either group. However when collagen was expressed by wet weight there was a negative correlation between % extractable and collagen in OA cartilage. The amount of GAG per wet weight was similar in both groups but the amount of GAG per dry weight was higher in OA samples compared to reference samples, which suggests a capacity for GAG biosynthesis in hip OA cartilage. Neither of the studied parameters was related to age in either group. Conclusions Increased collagen extractability and water content in human hip cartilage is associated with OA pathology and can be observed at

    A symbiotic ecosystem is studied by means of the Lotka-Volterra stochastic model, using the generalized Verhulst self-regulation. The effect of fluctuating environment on the carrying capacity of a population is taken into account as dichotomous noise. The study is a follow-up of our investigation of symbiotic ecosystems subjected to three-level (trichotomous) noise [R. Mankin, A. Ainsaar, A. Haljas, and E. Reiter, Phys. Rev. E 65, 051108 (2002)]. Relying on the mean-field theory, an exact self-consistency equation for stationary states is derived. In some cases the mean field exhibits hysteresis as a function of noise parameters. It is established that random interactions with the environment can cause discontinuous transitions. The dependence of the critical coupling strengths on the noise parameters is found and illustrated by phase diagrams. Predictions from the mean-field theory are compared with the results of numerical simulations. Our results provide a possible scenario for catastrophic shifts of population sizes observed in nature.

    To determine whether there is a correlation between the concentration of Indian hedgehog (Ihh) in synovial fluid (SF) and the severity of cartilage damage in the human knee joints, the knee cartilages from patients were classified using the Outer-bridge scoring system and graded using the Modified Mankin score. Expression of Ihh in cartilage and SF samples were analyzed with immunohistochemistry (IHC), western blot, and enzyme-linked immunosorbent assay (ELISA). Furthermore, we detected and compared Ihh protein levels in rat and mice cartilages between normal control and surgery-induced osteoarthritis (OA) group by IHC and fluorescence molecular tomography in vivo respectively. Ihh expression was increased 5.2-fold in OA cartilage, 3.1-fold in relative normal OA cartilage, and 1.71-fold in OA SF compared to normal control samples. The concentrations of Ihh in cartilage and SF samples was significantly increased in early-stage OA samples when compared to normal samples (r = 0.556; p Ihh protein was also an early event in the surgery-induced OA models. Increased Ihh is associated with the severity of OA cartilage damage. Elevated Ihh content in human knee joint synovial fluid correlates with early cartilage lesions. PMID:24786088

    This study was conducted to evaluate the long-term oncological and functional outcomes. Forty-two patients (29 men and 13 women) with primary malignant bone tumors were included in this study. The procedure consisted of wide en bloc resection, clearing the extraosseous soft tissue and medullary content, extracorporeal irradiation with a single dose of 50 Gy using linear accelerator, and reimplantation using suitable fixation devices. The mean survivor follow-up was 54 months (24-174 months). There were 32 (76.2%) patients continuously disease free, 7 (16.7%) died of disease, and 3 (7.1%) alive with disease. Local recurrence was encountered in 4 (9.5%) patients. Nonunion occurred at 3 (6.4%) osteotomy sites. Deep infection developed in 4 (9.5%) cases. There were 13 patients rated excellent, 17 good, 10 fair, and 2 failures according to the Mankin scoring system. The mean ratings of the Musculoskeletal Tumor Society score and the Toronto Extremity Salvage Score were 77 and 81, respectively. The long-term oncological and functional results are encouraging and suggest that extracorporeal irradiation and reimplantation can be a long-lasting biological reconstructive technique in properly selected patients.

    2009-08-01

    Neurological histories of great musicians allow for a unique perspective on music physiology. Bedrich Smetana's autobiographical string quartet ends with the musical equivalent of tinnitus in the fourth movement, rendering the youthful and passionate themes of earlier movements moot as the piece ends depicting his ultimately fatal disease, neurosyphilis. Dmitri Shostakovich survived the censorship of Joseph Stalin's apparatchiks but suffered a prolonged form of paralysis attributable to slowly progressive motor neuron disease, although the viola sonata he wrote on his deathbed has become standard repertoire. Glenn Gould was a hypochondriacal pianist with obsessive-compulsive disorder and suspected Asperger syndrome. Vissarion Shebalin and (Ira) Randall Thompson had strokes followed by aphasia without amusia. Domenico Scarlatti provides an example of how even great composers must alter their technical expectations depending upon the skills and body habitus of their chief patrons. The focal dystonia afflicting Leon Fleisher and Gary Graffman catalyzed the discipline of performing arts medicine.

    Osteoarthritis (OA) is characterized by degradation of chondrocyte extracellular matrix (ECM). Accumulating evidence suggests that microRNAs (miRNAs) are associated with OA, but little is known of their function in chondrocyte ECM degradation. The objective of this study was to investigate the expression and function of miRNAs in OA. miRNA expression profile was determined in OA cartilage tissues and controls, employing Solexa sequencing and reverse transcription quantitative PCR (RT-qPCR). According to a modified Mankin scale, cartilage degradation was evaluated. Functional analysis of the miRNAs on chondrocyte ECM degradation was performed after miRNA transfection and IL-1β treatment. Luciferase reporter assays and western blotting were employed to determine miRNA targets. Expression of miR-221-3p was downregulated in OA cartilage tissues, which was significantly correlated with a modified Mankin scale. Through gain-of-function and loss-of-function studies, miR-221-3p was shown to significantly affect matrix synthesis gene expression and chondrocyte proliferation and apoptosis. Using SW1353 and C28I2 cells, SDF1 was identified as a target of miR-221-3p. SDF1 overexpression resulted in increased expression of catabolic genes such as MMP-13 and ADAMTS-5 in response to IL-1β, but these effects were moderated by miR-221-3p. SDF1 treatment antagonized this effect, while knockdown of SDF1 by shSDF1 induced inhibitory effects on the expression of CXCR4 and its main target genes, similar to miR-221-3p. The results indicate that upregulation of miR-221-3p could prevent IL-1β-induced ECM degradation in chondrocytes. Targeting the SDF1/CXCR4 signaling pathway may be used as a therapeutic approach for OA. miR-221-3p is downregulated in human cartilage tissues. miR-221-3p levels are associated with cartilage degeneration grade. miR-221-3p upregulation prevents IL-1β-induced ECM degradation in chondrocytes. Protection of ECM degradation by miR-223-3p occurs via SDF1/CXCR4

    The aim of this study was to evaluate the effects of laser phototherapy on the degenerative modifications on the articular cartilage after the anterior cruciate ligament transection (ACLT) in the knee of rats. Eighty male rats (Wistar) were distributed into four groups: intact control group (IG), injured control group (CG), injured laser treated group at 10 J/cm2 (L10), and injured laser treated group at 50 J/cm2 (L50). Animals were distributed into two subgroups, sacrificed in 5 and 8 weeks postsurgery. The ACLT was used to induce knee osteoarthritis in rats. After 2 weeks postsurgery, laser phototherapy initiated and it was performed for 15 and 30 sessions. The histological findings revealed that laser irradiation, especially at 10 J/cm2, modulated the progression of the degenerative process, showing a better cartilage structure and lower number of condrocytes compared to the other groups. Laser phototherapy was not able to decrease the degenerative process measured by Mankin score and prevent the increase of cartilage thickness related to the degenerative process. Moreover, it did not have any effect in the biomodulation of the expression of markers IL1β, tumor necrosis factor-α, and metalloprotein-13. Furthermore, laser irradiated animals, at 50 J/cm2 showed a lower amount of collagen type 1.

    Full Text Available Although there have been augmented advances in drug discovery, current OA management is inadequate due to the lack of successful therapies proven to be effective in modifying disease progression. For some, the risk outweighs the benefit. As a result, there is a desperate need for safe and efficacious natural alternatives. Here we evaluated a composition from Morus alba, Scutellaria baicalensis, and Acacia catechu in maintaining joint structural integrity and alleviating OA associated symptoms in monoiodoacetate- (MIA- induced rat OA disease model. Study lasted for 6 weeks. 59.6%, 64.6%, 70.7%, 69.9%, and 70.3% reductions in pain sensitivity were observed for rats treated with the composition from week 1 to week 5, respectively. Statistically significant improvements in articular cartilage matrix integrity (maintained at 57.1% versus MIA + vehicle treated rats were shown from the modified total Mankin score for animals treated with the composition. The composition showed a statistically significant reduction in uCTX-II level (54.1% reductions. The merit of combining these botanicals was also demonstrated in their synergistic analgesic activity. Therefore, the standardized blend of Morus alba, Scutellaria baicalensis, and Acacia catechu could potentially be considered as an alternative remedy from natural sources for the management of OA and/or its associated symptoms.

    Epidemiological evidence indicates that osteoarthritis (OA) and prenatal ethanol exposure (PEE) are both associated with low birth weight but possible causal interrelationships have not been investigated. To investigate the effects of PEE on the susceptibility to OA in adult rats that experienced intrauterine growth retardation (IUGR), and to explore potential intrauterine mechanisms, we established the rat model of IUGR by PEE and dexamethasone, and the female fetus and 24-week-old adult offspring subjected to strenuous running for 6 weeks were sacrificed. Knee joints were collected from fetuses and adult offspring for histochemistry, immunohistochemistry and qPCR assays. Histological analyses and the Mankin score revealed increased cartilage destruction and accelerated OA progression in adult offspring from the PEE group compared to the control group. Immunohistochemistry showed reduced expression of insulin-like growth factor-1 (IGF-1) signaling pathway components. Furthermore, fetuses in the PEE group experienced IUGR but exhibited a higher postnatal growth rate. The expression of many IGF-1 signaling components was downregulated, which coincided with reduced amounts of type II collagen in the epiphyseal cartilage of fetuses in the PEE group. These results suggest that PEE enhances the susceptibility to OA in female adult rat offspring by down-regulating IGF-1 signaling and retarding articular cartilage development.

    This study investigated the therapeutic potential of low-intensity pulsed ultrasound (LIPUS) in post-traumatic osteoarthritis (PTOA). Intra-articular fracture of the medial tibial plateau was surgically created in 30 rats. LIPUS was applied to the operated joints either for the first 2 wk (LIPUS 1-2 group) or in weeks 4 and 5 after intra-articular fracture (LIPUS 4-5 group). In controls, the operated knees were not treated with LIPUS (LIPUS 0 group). The rats were monitored with weekly gait analysis and euthanized at week 8. Among the altered gait parameters, the maximal and average paw print areas in the LIPUS 1-2 and LIPUS 4-5 groups, but not the LIPUS 0 group, had either reached baseline or significantly recovered (70%, p <0.05) by week 8. PTOA pathology in both the LIPUS 1-2 and LIPUS 4-5 groups was less severe than that in the LIPUS 0 group (Mankin score: 5.4 and 4.5 vs. 8.8, p <0.05). In conclusion, LIPUS treatment partially improved the gait of the affected limbs and reduced cartilage degeneration in PTOA. Copyright © 2018 World Federation for Ultrasound in Medicine and Biology.

    Autologous osteochondral grafting is a well-established clinical procedure to treat focal cartilage defects in patients, although basic research on this topic remains sparse. The aim of the current study was to evaluate (1) histological changes of transplanted hyaline cartilage of osteochondral grafts and (2) the tissue that connects the transplanted cartilage with the adjacent cartilage in a sheep model. Both knee joints of four sheep were opened surgically and osteochondral grafts were harvested and simultaneously transplanted to the contralateral femoral condyle. The animals were sacrificed after three months and the received knee joints were evaluated histologically. Histological evaluation showed a complete ingrowth of the osseous part of the osteochondral grafts. A healing or ingrowth at the level of the cartilage could not be observed. Histological evaluation of the transplanted grafts according to Mankin revealed significantly more and more severe signs of degeneration than the adjacent cartilage, such as cloning of chondrocytes and irregularities of the articular surface. We found no connecting tissue between the transplanted and the adjacent cartilage and histological signs of degeneration of the transplanted hyaline cartilage. In the light of these findings, long-term results of autologous osteochondral grafts in human beings have to be followed critically.

Attempts are put, besides defin­ing the Christian stratum of the Russian culture, to establish the methodology of the research. The ar­ticle highlights the unique character of the theology of the Orthodox literature, mainly anchored to the ideas of the Russian religious philosophy reflected in the works of the Russian thinkers and writers as Vladimir Solovyov, Nikolai Berdyaev, Dmitri Mer­ezhkovski, Fyodor Dostoyevsky, Andrei Bely and others. The article discusses the theologemes char­acteristic of the Orthodox literature: the depiction of Sophia, theurgic parameter, the ontological character of creation, performativeness, religious anthropol­ogy of Dostoyevsky. The uniqueness of the relation­ship between the Orthodoxy and literature is defined by demonstrating its link with religious philosophy, the aesthetic parameter of the existence, the role of religious ideas in literature, and the significance of theurgic aesthetics.

    Full Text Available Toonaciliatin K is a natural limonoid purified from the Toona ciliata Roem. var. ciliata (Meliaceae. This study is to reveal the inflammatory suppression effect of toonaciliatin K and further the intrinsic mechanism. Firstly, anti-inflammatory effect of toonaciliatin K was evaluated in lipopolysaccharide- (LPS- induced RAW264.7 cells. RT-PCR results indicated that the mRNA expressions of TNF-α, IL-6, and IL-1β were downregulated by toonaciliatin K. The toonaciliatin K inhibited TNF-α, IL-6, and IL-1β levels stimulated by LPS. Furthermore, LPS elicited the excess iNOS and COX-2 mRNA and protein production and toonaciliatin K attenuated the excess production. Western blot assay demonstrated that MAPK and NF-κB signaling pathways play critical roles in the toonaciliatin K’s anti-inflammatory activity. Secondly, toonaciliatin K inhibited carrageenan-induced paw edema in rats. Thirdly, toonaciliatin K alleviated the paw swelling and improved arthritis clinical scores in the adjuvant arthritis rats. Toonaciliatin K decreased the proinflammatory cytokines levels and Mankin scores in adjuvant arthritis rats. The HE staining, safranin O-fast green, and toluidine blue staining results demonstrated that toonaciliatin K alleviated the histological changes of paw, for example, pannus formation, focal loss of cartilage, bone erosion, and presence of extra-articular inflammation. Hence, toonaciliatin K is a promising agent for treatment of arthritis.

    Full Text Available To determine whether there is a correlation between the concentration of Indian hedgehog (Ihh in synovial fluid (SF and the severity of cartilage damage in the human knee joints, the knee cartilages from patients were classified using the Outer-bridge scoring system and graded using the Modified Mankin score. Expression of Ihh in cartilage and SF samples were analyzed with immunohistochemistry (IHC, western blot, and enzyme-linked immunosorbent assay (ELISA. Furthermore, we detected and compared Ihh protein levels in rat and mice cartilages between normal control and surgery-induced osteoarthritis (OA group by IHC and fluorescence molecular tomography in vivo respectively. Ihh expression was increased 5.2-fold in OA cartilage, 3.1-fold in relative normal OA cartilage, and 1.71-fold in OA SF compared to normal control samples. The concentrations of Ihh in cartilage and SF samples was significantly increased in early-stage OA samples when compared to normal samples (r = 0.556; p < 0.001; however, there were no significant differences between normal samples and late-stage OA samples. Up-regulation of Ihh protein was also an early event in the surgery-induced OA models. Increased Ihh is associated with the severity of OA cartilage damage. Elevated Ihh content in human knee joint synovial fluid correlates with early cartilage lesions.

    Our objective was to test the efficacy of collagen-hyaluronan scaffolds reinforced with poly(l-lactic acid) (PLLA) fibers in an ovine total meniscus replacement model. Scaffolds were implanted into 9 sheep (n = 1 at 8 weeks, n = 2 at 16 weeks, n = 3 at both 24, 32 weeks) following total medial meniscectomy. From 16 weeks on, explants were characterized by confined compression creep, histological, and biochemical analyses. Articular surfaces were observed macroscopically and damage was ranked histologically using the Mankin score. At sacrifice, three of the nine PLLA scaffolds had completely ruptured, and the intact scaffolds experienced progressive shape changes and severe narrowing in the body region at 16, 24, and 32 weeks. Aggregate compressive modulus and permeability did not improve with time. Histological and biochemical analyses showed significantly less extracellular matrix and less matrix organization compared to native tissue. Osteophytes, bone erosion, and cartilage damage were observed, increasing with time postimplantation. A buildup of lactic acid and/or the rapid loss of scaffold mechanical integrity due to PLLA degradation are probable causes for the joint abnormalities observed in this study. These results are in sharp contrast to those of our previous successful total meniscus replacement studies using polyarylate [p(DTD DD)] fiber-reinforced scaffolds. This suggests that PLLA fiber as produced in this study cannot be used as reinforcement for a meniscus replacement scaffold.

    The photometry of coronal negatives is carried out. The films were obtained at the March 7, 1970 and July 10, 1972 eclipses. A distribution of the coronal brightness in the red (635 mm), green (545 nm), and blue (455 nm) wavelength intervals up to distances of (6-7)Rsub(sun) is deduced (Figure 1). Colour indexes of the corona (the emission ratio red/blue-Csub(rb) and green/blue-Csub(gb)) have been obtained. We assume Csub(rb) = Csub(gb) = 1 in the inner corona ( = 1 μm. RED brightness is evaluated to be 4 x 10 -10 anti Bsub(sun). There is 1 grain of dust in the elementary volume with cross section of 1 cm 2 along the line of sight. The intensity of dust emission in wavelength interval 10 μm deduced by the authors is approximately 1 μ W cm -2 sm -1 . That is in agreement with Mankin et al. (1974) and Lena et al. (1974) observations. The whole dust mass of RED is -11 cm -3 . Determination of the colour of the solar corona have been made by a number of scientists (Tikhov, 1940, 1957; Allen, 1946; Blackwell, 1952; Michard, 1956; Sharonov, 1958; Nay et al. 1961). The corona colour was found to be somewhat redder than the Sun's. However this question is not finally settled to date. (orig.)

    Full Text Available The decrease in insecurity in the North Caucasus during the first eight years of the 21st century was achieved with the help of federal money used to amnesty soldiers and to pacify ethnic leaders' ambitions. But circumstances changed after Dmitry Kozak's announcement that the federal budget for the entire region would decrease significantly. As all the republics in the North Caucasus are dependent on federal aid of no less than 50% (in Ingushetia, Chechnya and Dagestan dependence is superior to 80%, such cut represented a politically potential danger. The main goal of the article is to present a deeper understanding of the potential link between the international and regional economic dynamics and the current acceleration of social disruption in the North Caucasus region. The paper explains how ethno-political and transition studies can benefit from the inclusion of the economic dimension into the analysis, and so it clarifies the importance of a bi-level analysis using two concepts: economic society and economic security. The paper employs the concepts of economic security and economic society to perform a richer and innovative analysis.

    Sheep hips have a natural non-spherical femoral head similar to a cam-type deformity in human beings. By performing an intertrochanteric varus osteotomy, cam-type femoro-acetabular impingement (FAI) during flexion can be created. We tested the hypotheses that macroscopic lesions of the articular cartilage and an increased Mankin score (MS) can be reproduced by an experimentally induced cam-type FAI in this ovine in vivo model. Furthermore, we hypothesized that the MS increases with longer ambulatory periods. Sixteen sheep underwent unilateral intertrochanteric varus osteotomy of the hip with the non-operated hip as a control. Four sheep were sacrificed after 14, 22, 30, and 38-weeks postoperatively. We evaluated macroscopic chondrolabral alterations, and recorded the MS, based on histochemical staining, for each ambulatory period. A significantly higher prevalence of macroscopic chondrolabral lesions was found in the impingement zone of the operated hips. The MS was significantly higher in the acetabular/femoral cartilage of the operated hips. Furthermore, these scores increased as the length of the ambulatory period increased. Cam-type FAI can be induced in an ovine in vivo model. Localized chondrolabral degeneration of the hip, similar to that seen in humans (Tannast et al., Clin Orthop Relat Res 2008; 466: 273-280; Beck et al., J Bone Joint Surg Br 2005; 87: 1012-1018), can be reproduced. This experimental sheep model can be used to study cam-type FAI. Copyright © 2012 Orthopaedic Research Society.

    The hip is one of the most common sites of osteoarthritis in the body, second only to the knee in prevalence. However, current animal models of hip osteoarthritis have not been assessed using many of the functional outcome measures used in orthopaedics, a characteristic that could increase their utility in the evaluation of therapeutic interventions. The canine hip shares similarities with the human hip, and functional outcome measures are well documented in veterinary medicine, providing a baseline for pre-clinical evaluation of therapeutic strategies for the treatment of hip osteoarthritis. The purpose of this study was to evaluate a surgical model of hip osteoarthritis in a large laboratory animal model and to evaluate functional and end-point outcome measures. Seven dogs were subjected to partial surgical debridement of cartilage from one femoral head. Pre- and postoperative pain and functional scores, gait analysis, radiographs, accelerometry, goniometry and limb circumference were evaluated through a 20-week recovery period, followed by histological evaluation of cartilage and synovium. Animals developed histological and radiographic evidence of osteoarthritis, which was correlated with measurable functional impairment. For example, Mankin scores in operated limbs were positively correlated to radiographic scores but negatively correlated to range of motion, limb circumference and 20-week peak vertical force. This study demonstrates that multiple relevant functional outcome measures can be used successfully in a large laboratory animal model of hip osteoarthritis. These measures could be used to evaluate relative efficacy of therapeutic interventions relevant to human clinical care.

    Full Text Available Osteoarthritis is the most common human arthritis characterized by degeneration of articular cartilage. Several studies reported that levels of human cartilage glycoprotein chitinase 3-like-1 (CHI3L1 are known as a potential marker for the activation of chondrocytes and the progression of Osteoarthritis (OA, whereas lubricin appears to be chondroprotective. The aim of this study was to investigate the co-expression and co-localization of CHI3L1 and lubricin in normal and osteoarthritic rat articular cartilage to correlate their modified expression to a specific grade of OA. Samples of normal and osteoarthritic rat articular cartilage were analyzed by the Kellgren–Lawrence OA severity scores, the Kraus’ modified Mankin score and the Histopathology Osteoarthritis Research Society International (OARSI system for histomorphometric evaluations, and through CHI3L1 and lubricin gene expression, immunohistochemistry and double immuno-staining analysis. The immunoexpression and the mRNA levels of lubricin increased in normal cartilage and decreased in OA cartilage (normal vs. OA, p < 0.01. By contrast, the immunoexpression and the mRNA levels of CHI3L1 increased in OA cartilage and decreased in normal cartilage (normal vs. OA, p < 0.01. Our findings are consistent with reports suggesting that these two glycoproteins are functionally associated with the development of OA and in particular with grade 2/3 of OA, suggesting that in the future they could be helpful to stage the severity and progression of the disease.

    Full Text Available Arthropathy of the distal articular surfaces of the third metacarpal (Mc3 and metatarsal (Mt3 bones in the Thoroughbred racehorse (Tb is a natural model of repetitive overload arthrosis. We describe a novel pathology that affects the articular calcified cartilage (ACC and subchondral bone (SCB and which is associated with hyaline articular cartilage degeneration. Parasagittal slices cut from the palmar quadrant of the distal condyles of the left Mc3/Mt3 of 39 trained Tbs euthanased for welfare reasons were imaged by point projection microradiography, and backscattered electron (BSE scanning electron microscopy (SEM, light microscopy, and confocal scanning light microscopy. Mechanical properties were studied by nanoindentation. Data on the horses' training and racing career were also collected. Highly mineralised projections were observed extending from cracks in the ACC mineralising front into the hyaline articular cartilage (HAC up to two-thirds the thickness of the HAC, and were associated with focal HAC surface fibrillation directly overlying their site. Nanoindentation identified this extruded matrix to be stiffer than any other mineralised phase in the specimen by a factor of two. The presence of projections was associated with a higher cartilage Mankin histology score (P < 0.02 and increased amounts of gross cartilage loss pathologically on the condyle (P < 0.02. Presence of projections was not significantly associated with: total number of racing seasons, age of horse, amount of earnings, number of days in training, total distance galloped in career, or presence of wear lines.

    The current generation of high-energy-density research facilities has enabled the beginnings of experimental studies of radiation hydrodynamic systems, common in astrophysics but difficult to produce in the laboratory. Radiative shock experiments specifically have been a topic of increasing effort in recent years. Our group and collaborators [1] have emphasized the radiographic observation of structure in radiative shocks. These shocks have been produced on the Omega laser by driving a Be piston through Xenon at velocities above 100 km/s. The talk will summarize these experiments and their results. Interpreting these and other experiments is hampered by the limited range of assumptions used in published theories, and by the limitations in readily available simulation tools. This has motivated an examination of radiative shock theory [2]. The talk will summarize the key issues and present results for specific cases.

    The behavior of flux ropes is a key issue in solar, space and astrophysics. For instance, magnetic fields and currents on the Sun are sheared and twisted as they store energy, experience an as yet unidentified instability, open into interplanetary space, eject the plasma trapped in them, and cause a flare. The Reconnection Scaling Experiment (RSX) provides a simple means to systematically characterize the linear and non-linear evolution of driven, dissipative, unstable plasma-current filaments. Topology evolves in three dimensions, supports multiple modes, and can bifurcate to quasi-helical equilibria. The ultimate saturation to a nonlinear force and energy balance is the link to a spectrum of relaxation processes. RSX has adjustable energy density β1 to β 1, non-negligible equilibrium plasma flows, driven steady-state scenarios, and adjustable line tying at boundaries. We will show magnetic structure of a kinking, rotating single line tied column, magnetic reconnection between two flux ropes, and pictures of three braided flux ropes. We use computed simulation movies to bridge the gap between the solar physics scales and experimental data with computational modeling.

  15. Gallium--A smart metal

    Foley, Nora; Jaskula, Brian W.

    2013-01-01

    Gallium is a soft, silvery metallic element with an atomic number of 31 and the chemical symbol Ga. The French chemist Paul-Emile Lecoq de Boisbaudran discovered gallium in sphalerite (a zinc-sulfide mineral) in 1875 using spectroscopy. He named the element "gallia" after his native land of France (formerly Gaul; in Latin, Gallia). The existence of gallium had been predicted in 1871 by Dmitri Mendeleev, the Russian chemist who published the first periodic table of the elements. Mendeleev noted a gap in his table and named the missing element "eka-aluminum" because he determined that its location was one place away from aluminum in the table. Mendeleev thought that the missing element (gallium) would be very much like aluminum in its chemical properties, and he was right. Solid gallium has a low melting temperature (~29 degrees Celsius, or °C) and an unusually high boiling point (~2,204 °C). Because of these properties, the earliest uses of gallium were in high-temperature thermometers and in designing metal alloys that melt easily. The development of a gallium-based direct band-gap semiconductor in the 1960s led to what is now one of the most well-known applications for gallium-based products--the manufacture of smartphones and data-centric networks.

    Oxidized zirconium (OxZr) is produced by thermally driven oxidization creating an oxidized surface with the properties of a ceramic at the top of the Zr metal substrate. OxZr is much harder and has a lower coefficient of friction than cobalt-chrome (CoCr), both leading to better wear characteristics. We evaluated and compared damage to the cartilage of porcine patella plugs, articulating against OxZr vs CoCr. Our hypothesis was that, owing to its better wear properties, OxZr would damage cartilage less than CoCr. If this is true, OxZr might be a better material for the femoral component during total knee arthroplasty if the patella is not resurfaced. Twenty-one plugs from porcine patellae were prepared and tested in a reciprocating pin-on-disk machine while lubricated with bovine serum and under a constant load. Three different configurations were tested: cartilage-cartilage as the control group, cartilage-OxZr, and cartilage-CoCr. Macroscopic appearance, cartilage thickness, and the modified Mankin score were evaluated after 400,000 wear cycles. The control group showed statistically significant less damage than plugs articulating against both other materials. Cartilage plugs articulating against OxZr were statistically significantly less damaged than those articulating against CoCr. Although replacing cartilage by an implant always leads to deterioration of the cartilage counterface, OxZr results in less damage than CoCr. The use of OxZr might thus be preferable to CoCr in case of total knee arthroplasty without patella resurfacing. Copyright © 2016 Elsevier Inc. All rights reserved.

    Meniscectomy (MX) of sheep induces a well-established animal model of human osteoarthritis (OA). This study compared the clinical (lameness) and pathological outcomes of unilateral, complete medial MX vs two less traumatic and more easily performed meniscal destabilisation procedures. Four-year old wethers (n = 6/group) underwent sham operation, cranial pole release (CPR), mid-body transection (MBT) or total MX of the medial meniscus. Joints were assessed for gross pathology (cartilage erosion and osteophytes), histomorphometry, two histopathology scoring methods (modified Mankin-type and Pritzker score), and immunohistology for ADAMTS- and MMP-cleaved neoepitopes, at 12 weeks post-op. Ground reaction forces (GRFs) were determined by force plate in a subset (n = 4/group) at baseline, 2.5, 8, and 12 weeks post-op. Gross pathology scores of operated groups differed significantly from sham animals (P osteophyte formation. Similarly, histopathology scores were significantly elevated vs sham but did not differ between operated groups at P subchondral sclerosis, suggesting some residual biomechanical effect from the destabilised but intact meniscus. Few significant differences were noted between operated groups in force plate analyses, though gait abnormalities appeared to be least in CPR sheep, and most persistent (>12 weeks) in MBT animals. The well-validated ovine MX model and the simpler meniscal destabilisation procedures resulted in broadly similar joint pathology and lameness. Meniscal CPR or MBT, as easier and more clinically relevant procedures, may represent preferred models for the induction of OA and evaluation of potential disease-modifying therapies.

    Osteoarthritis (OA) is a heterogeneous, multi-tissue disease. We hypothesised that different histopathological features characterise different stages during knee OA progression, and that discrete subgroups can be defined based on validated measures of OA histopathological features. Medial tibial plateaux and synovium were from 343 post-mortem (PM) and 143 OA arthroplasty donations. A 'chondropathy/osteophyte' group (n = 217) was classified as PM cases with osteophytes or macroscopic medial tibiofemoral chondropathy lesions ≥grade 3 to represent pre-surgical (early) OA. 'Non-arthritic' controls (n = 48) were identified from the remaining PM cases. Mankin histopathological scores were subjected to Rasch analysis and supplemented with histopathological scores for subchondral bone marrow replacement and synovitis. Item weightings were derived by principle components analysis (PCA). Histopathological subgroups were sought using latent class analysis (LCA). Chondropathy, synovitis and osteochondral pathology were each associated with OA at arthroplasty, but each was also identified in some 'non-arthritic' controls. Tidemark breaching in the chondropathy/osteophyte group was greater than in non-arthritic controls. Three histopathological subgroups were identified, characterised as 'mild OA', or 'severe OA' with mild or moderate/severe synovitis. Presence and severity of synovitis helps define distinct histopathological OA subgroups. The absence of a discrete 'normal' subgroup indicates a pathological continuum between normality and OA status. Identifying specific pathological processes and their clinical correlates in OA subgroups has potential to accelerate the development of more effective therapies.

    Dunkin Hartley guinea pigs develop spontaneous, age-related osteoarthritis (OA) of the knee and other joints. Histologic changes are observed beginning at 3 months of age. Disease severity increases with age, and at 18 months moderate to severe OA is observed. A study was undertaken to assess the morphologic and biochemical changes of 22-month-old animals, and to compare them with values in 2-month-old guinea pigs. Biochemical indices characteristic of OA, from tibial cartilage, indicated an increase in proteoglycan content from 283 +/- 2 micrograms/mg (mean +/- SEM) at 2 months of age to 365 +/- 6 micrograms/mg at 22 months. Collagen concentration in cartilage decreased from 364 +/- 2 micrograms/ at 2 months to 223 +/- 3 micrograms/mg at 22 months. Proteoglycan fragments found in synovial fluid measured 4.6 +/- 1 micrograms/ml at 2 months and increased to 37 +/- 2 micrograms/ml at 22 months. Radiographic changes observed at 22 months included marginal osteophytes of the tibia and femur, sclerosis of the subchondral bone of the tibial plateau, femoral condyle cysts, and calcification of the collateral ligaments. Histologic evaluation revealed severe OA, with a Mankin score of 10.7 +/- 0.5 in 22-month-old animals. In contrast, 2-month-old animals had no histologic or radiographically detectable lesions. The results of the study reported here indicate that the lesions observed in this model are similar to those of human OA. Spontaneous development of OA in guinea pig is amenable to the study of the pathogenesis of OA and to the evaluation of potential disease-modifying agents

    The aim of this study was to determine if extracorporeal shock wave therapy (ESWT) in vivo affects the structural integrity of articular cartilage. A single bout of ESWT (1500 shock waves of 0.5 mJ/mm(2)) was applied to femoral heads of 18 adult Sprague-Dawley rats. Two sham-treated animals served as controls. Cartilage of each femoral head was harvested at 1, 4, or 10 weeks after ESWT (n = 6 per treatment group) and scored on safranin-O-stained sections. Expression of tenascin-C and chitinase 3-like protein 1 (Chi3L1) was analyzed by immunohistochemistry. Quantitative real-time polymerase chain reaction (PCR) was used to examine collagen (II)alpha(1) (COL2A1) expression and chondrocyte morphology was investigated by transmission electron microscopy no changes in Mankin scores were observed after ESWT. Positive immunostaining for tenascin-C and Chi3L1 was found up to 10 weeks after ESWT in experimental but not in control cartilage. COL2A1 mRNA was increased in samples 1 and 4 weeks after ESWT. Alterations found on the ultrastructural level showed expansion of the rough-surfaced endoplasmatic reticulum, detachment of the cell membrane and necrotic chondrocytes. Extracorporeal shock waves caused alterations of hyaline cartilage on a molecular and ultrastructural level that were distinctly different from control. Similar changes were described before in the very early phase of osteoarthritis (OA). High-energy ESWT might therefore cause degenerative changes in hyaline cartilage as they are found in initial OA.

    Full Text Available This paper focuses on the rhetoric of USA and Russian political leaders during the Ukraine crisis by analyzing changes appearing in their speeches during the different stages of the crisis. The goal of the analysis is to investigate the speeches delivered by political leaders of the United States and Russia, being important actors in the Ukraine crisis, by identifying both countries’ attitudes to one another, further intentions regarding the management of the crisis and changes of topics in each stage. The speeches of the following most influential politicians in foreign policy formation in the USA and Russia are analyzed: President Barack Obama, Secretary of State John Kerry and Vice President Joe Biden, President Vladimir Putin, Russian Foreign Minister Sergey Lavrov and Prime Minister of Russia Dmitry Medvedev. The speeches were collected from the official websites of U.S. and Russian government institutions. The analysis revealed that from the beginning of the crisis the main tool in the Ukraine crisis was rhetoric. Western parties began to take real actions only later: sanctions on Russia were imposed, international organizations started to play more active role, ceasefire agreements were signed. In terms of communications strategies used by both countries, the USA rhetoric and its communication strategy as well as Russian leaders were using a combination of proactive and reactive strategies.

    The anticipated upcoming large mission study concepts for the direct imaging of exo-earths present an exciting opportunity for exoplanet discovery and characterization. While these telescope concepts would also be capable of conducting a broad range of astrophysical investigations, the most difficult technology challenges are driven by the requirements for imaging exo-earths. The exoplanet science yield for these mission concepts will drive design trades and mission concept comparisons.To assist in these trade studies, the Exoplanet Exploration Program Office (ExEP) is developing a yield estimation tool that emphasizes transparency and consistent comparison of various design concepts. The tool will provide a parametric estimate of science yield of various mission concepts using contrast curves from physics-based model codes and Monte Carlo simulations of design reference missions using realistic constraints, such as solar avoidance angles, the observatory orbit, propulsion limitations of star shades, the accessibility of candidate targets, local and background zodiacal light levels, and background confusion by stars and galaxies. The python tool utilizes Dmitry Savransky's EXOSIMS (Exoplanet Open-Source Imaging Mission Simulator) design reference mission simulator that is being developed for the WFIRST Preliminary Science program. ExEP is extending and validating the tool for future mission concepts under consideration for the upcoming 2020 decadal review. We present a validation plan and preliminary yield results for a point design.

    Osteoarthritis is a degenerative joint disease mostly occurring in the knee and commonly seen in middle-aged and elderly adults. Intra-articular injection of hyaluronic acid has been widely used for treatment of knee osteoarthritis. The aim of this study was to evaluate the efficacy of intra-articular injection of a novel highly cross-linked hyaluronic acid, alone or in combination with ropivacaine hydrochloride and triamcinolone acetonide, on knee articular cartilage in a rabbit model of collagenase-induced knee osteoarthritis. After induction of experimental osteoarthritis by intra-articular injection of collagenase, adult New Zealand white rabbits (n = 12) were divided into 3 groups. Group 1 (control group) received 0.3 ml phosphate buffered saline into the right knee joint. Group 2 received 0.3 ml cross-linked hyaluronic acid (33 mg/ml) into the right knee joint. Group 3 received a mixture of 0.15 ml cross-linked hyaluronic acid (33 mg/ml), 0.05 ml ropivacaine hydrochloride 1 % and 0.1 ml triamcinolone acetonide (10 mg/ml) into the right knee joint. Intra-articular injections were given 4 weeks after first collagenase injection and were administered once a week for 3 weeks. Gross pathology and histological evaluation of rabbits' knee joints were performed after 16 weeks following initial collagenase injection. Histological analysis of sections of right knee joints at lesion sites showed a significant decrease in Mankin's score in groups treated with hyaluronic acid alone or in combination with ropivacaine hydrochloride and triamcinolone acetonide versus control group (p hyaluronic acid, alone or in combination with ropivacaine hydrochloride and triamcinolone acetonide, produces a significant improvement in knee articular cartilage degeneration in a rabbit model of collagenase-induced osteoarthritis.

  7. Turning great strategy into great performance.

    2005-01-01

    Despite the enormous time and energy that goes into strategy development, many companies have little to show for their efforts. Indeed, research by the consultancy Marakon Associates suggests that companies on average deliver only 63% of the financial performance their strategies promise. In this article, Michael Mankins and Richard Steele of Marakon present the findings of this research. They draw on their experience with high-performing companies like Barclays, Cisco, Dow Chemical, 3M, and Roche to establish some basic rules for setting and delivering strategy: Keep it simple, make it concrete. Avoid long, drawn-out descriptions of lofty goals and instead stick to clear language describing what your company will and won't do. Debate assumptions, not forecasts. Create cross-functional teams drawn from strategy, marketing, and finance to ensure the assumptions underlying your long-term plans reflect both the real economics of your company's markets and its actual performance relative to competitors. Use a rigorous analytic framework. Ensure that the dialogue between the corporate center and the business units about market trends and assumptions is conducted within a rigorous framework, such as that of "profit pools". Discuss resource deployments early. Create more realistic forecasts and more executable plans by discussing up front the level and timing of critical deployments. Clearly identify priorities. Prioritize tactics so that employees have a clear sense of where to direct their efforts. Continuously monitor performance. Track resource deployment and results against plan, using continuous feedback to reset assumptions and reallocate resources. Reward and develop execution capabilities. Motivate and develop staff. Following these rules strictly can help narrow the strategy-to-performance gap.

  8. Making star teams out of star players.

    2013-01-01

    Top talent is an invaluable asset: In highly specialized or creative work, for instance, "A" players are likely to be six times as productive as "B" players. So when your company has a crucial strategic project, why not multiply all that firepower and have a team of your best performers tackle it? Yet many companies hesitate to do this, believing that all-star teams don't work: Big egos will get in the way. The stars won't be able to work with one another. They'll drive the team Leader crazy. Mankins, Bird, and Root of Bain & Company believe it's time to set aside that thinking. They have seen all-star teams do extraordinary work. But there is a right way and a wrong way to organize them. Before you can even begin to assemble such a team, you need to have the right talent management practices, so you hire and develop the best people and know what they're capable of. You have to give the team appropriate incentives and leaders and support staffers who are stars in their own right. And projects that are ill-defined or small scale are not for all-star teams. Use them only for critical missions, and make sure their objectives are clear. Even with the right setup, things can still go wrong. The wise executive will take steps to manage egos, prune non-team-players, and prevent average coworkers from feeling completely undervalued. She will also invest a lot of time in choosing the right team Leader and will ask members for lots of feedback to monitor how that leader is doing.

  9. A comparison between platelet-rich plasma (PRP and hyaluronate acid on the healing of cartilage defects.

    Ji Liu

    Full Text Available Platelet-rich plasma (PRP has offered great promise for the treatment of cartilage degradation, and has been proved to have positive effects on the restoration of cartilage lesions. But no comparative work has been done between PRP and hyaluronate acid (HA concerning their restoring effect on cartilage defect, especially by means of animal experiments and histologic assessments. The purpose of the study was to compare the therapeutic effects of P-PRP and HA on osteoarthritis in rabbit knees. Thirty rabbits were used to establish the animal models by creating a cartilage defect of 5 mm in diameter on the condyles of the femurs, and were randomly divided into three groups: the P-PRP group, HA group and the control group. Then each group was treated with P-PRP, HA or saline solution, respectively. Six and twelve weeks later the rabbits were sacrificed and the samples were collected. The platelet number, the concentrations of growth factors of P-PRP and whole blood, and the IL-1β concentration in the joint fluid were investigated, and the histological assessment of the cartilage were performed according to Mankin's scoring system. Micro-CT was also used to evaluate the restoration of subchondral bone. The platelet concentration in P-PRP is 6.8 fold of that in the whole blood. The IL-1β level in the P-PRP group was lower than in the HA group (p<0.01 and in the control group (p<0.01. The restoration of the defected cartilage as well as the subchondral bone was better in the P-PRP group than in the HA group or the control group (P<0.05. Our data showed that P-PRP is better than HA in promoting the restoration of the cartilage and alleviating the arthritis caused by cartilage damage.

    Full Text Available 【Abstract】Objective: To study the feasibility of regenerating a whole menisci using poly- (3-hydroxybutyrate-co-3-hydroxyvalerate (PHBV scaffolds loaded with meniscal cells in rabbits undergoing total meniscectomy, and to explore its protective effect on cartilage degeneration. Methods: A solvent casting and particulate leaching technique was employed to fabricate biodegradable PHBV scaffolds into a meniscal shape. The proliferated meniscal cells were seeded onto the polymer scaffolds, transplanted into rabbit knee joints whose lateral menisci had been removed. Eight to 18 weeks after transplantation, the regenerated neomenisci were evaluated by gross and histological observations. Cartilage degeneration was assessed by Mankin score. Results: Eighteen weeks after transplantation, the implants formed neomenisci. Hematoxylin and eosin (HE staining of the neomenisci sections revealed regeneration of fibrocartilage. Type I collagen in the neomenisci was also proved similar to normal meniscal tissue by immunohistochemical analysis and Sirius scarlet trinitrophenol staining. Articular cartilage degeneration was observed 8 weeks after implantation. It was less severe as compared with that in total meniscectomy controls and no further degeneration was observed at 18 weeks. At that time, the regenerated neomenisci strongly resembled normal meniscal fibrocartilage in gross and histological appearance, and its mechani- cal property was also close to that of normal meniscus. Conclusions: The present study demonstrates the feasibility of tissue-engineering a whole meniscal structure in total meniscectomy rabbit models using biodegradable PHBV scaffolds together with cultured allogeneic meniscal cells. Cartilage degeneration is decreased. But long-term in vivo investigations on the histological structure and cartilage degeneration of the neomenisci regenerated by this method are still necessary to determine the clinical potential of this tissue

    Full Text Available Previously, we reported an improvement in the transfection efficiency of the plasmid DNA-chitosan (pDNA/CS complex by the utilization of phosphorylatable short peptide-conjugated chitosan (pSP-CS. In this study, we investigated the effects of pSP-CS-mediated gene transfection of interleukin-1 receptor antagonist protein (IL-1Ra combined with insulin-like growth factor-1 (IGF-1 in rabbit chondrocytes and in a rabbit model of cartilage defects. pBudCE4.1-IL-1Ra+igf-1, pBudCE4.1-IL-1Ra and pBudCE4.1-igf-1 were constructed and combined with pSP-CS to form pDNA/pSP-CS complexes. These complexes were transfected into rabbit primary chondrocytes or injected into the joint cavity. Seven weeks after treatment, all rabbits were sacrificed and analyzed. High levels of IL-1Ra and igf-1 expression were detected both in the cell culture supernatant and in the synovial fluid. In vitro, the transgenic complexes caused significant proliferation of chondrocytes, promotion of glycosaminoglycan (GAG and collagen II synthesis, and inhibition of chondrocyte apoptosis and nitric oxide (NO synthesis. In vivo, the exogenous genes resulted in increased collagen II synthesis and reduced NO and GAG concentrations in the synovial fluid; histological studies revealed that pDNA/pSP-CS treatment resulted in varying degrees of hyaline-like cartilage repair and Mankin score decrease. The co-expression of both genes produced greater effects than each single gene alone both in vitro and in vivo. The results suggest that pSP-CS is a good candidate for use in gene therapy for the treatment of cartilage defects and that igf-1 and IL-1Ra co-expression produces promising biologic effects on cartilage defects.

    Adipokines play roles in the pathogenesis of osteoarthritis (OA). Fatty acid binding protein 4 (FABP4) is a novel adipokine that is closely associated with obesity and metabolic diseases. The aim of this study was to discover the potential role of FABP4 in OA. Seventy-two FABP4 knockout mice (KO) in C57BL/6N background and wild-type littermates (WT) (male, 6-week-old) were fed with a high-fat diet (HFD, 60% calorie) or standard diet (STD, 11.6% calorie) for 3 months, 6 months and 9 months (n = 6 each). In the parallel study, forty-eight 6-week-old male WT mice were fed with HFD or STD, and simultaneously treated with daily oral gavage of selective FABP4 inhibitor BMS309403 (15 mg/kg/d) or vehicle for 4 months and 6 months (n = 6 each). Serum FABP4 and cartilage oligomeric matrix protein (COMP) concentration was quantified. Histological assessment of knee OA and micro-CT analysis of subchondral bone were performed. HFD induced obesity in mice. After 3 months and 6 months of HFD, KO mice showed alleviated cartilage degradation and synovitis, with significantly lower COMP, modified Mankin OA score, and MMP-13/ADAMTS4 expression. After 6 months and 9 months of HFD, KO mice showed less osteophyte formation and subchondral bone sclerosis. Chronic treatment of BMS309403 for 4 months and 6 months significantly alleviated cartilage degradation, but had no effects on the subchondral bone. Knocking out or pharmaceutical inhibition of FABP4 did not have significant effects on lean mice fed with STD. Knocking out or pharmaceutical inhibition of FABP4 alleviates OA induced by HFD in mice.

    Notch ligands and receptors have recently been shown to be differentially expressed in osteoarthritis (OA). We aim to further elucidate the functional role of Notch signalling in OA using Notch1 antisense transgenic (Notch1 AS) mice. Notch and hedgehog signalling were analysed by real-time PCR and immunohistochemistry. Notch-1 AS mice were employed as a model of impaired Notch signalling in vivo. Experimental OA was induced by destabilisation of the medial meniscus (DMM). The extent of cartilage destruction and osteophyte formation was analysed by safranin-O staining with subsequent assessment of the Osteoarthritis Research Society International (OARSI) and Mankin scores and µCT scanning. Collagen X staining was used as a marker of chondrocyte hypertrophy. The role of hairy/enhancer of split 1 (Hes-1) was investigated with knockdown and overexpression experiments. Notch signalling was activated in human and murine OA with increased expression of Jagged1, Notch-1, accumulation of the Notch intracellular domain 1 and increased transcription of Hes-1. Notch1 AS mice showed exacerbated OA with increases in OARSI scores, osteophyte formation, increased subchondral bone plate density, collagen X and osteocalcin expression and elevated levels of Epas1 and ADAM-TS5 mRNA. Inhibition of the Notch pathway induced activation of hedgehog signalling with induction of Gli-1 and Gli-2 and increased transcription of hedgehog target genes. The regulatory effects of Notch signalling on Gli-expression were mimicked by Hes-1. Inhibition of Notch signalling activates hedgehog signalling, enhances chondrocyte hypertrophy and exacerbates experimental OA including osteophyte formation. These data suggest that the activation of the Notch pathway may limit aberrant hedgehog signalling in OA. Published by the BMJ Publishing Group Limited.

    Osteoarthritis (OA) is a chronic joint disease characterized by cartilage destruction, subchondral bone sclerosis, and osteophyte formation. Subchondral bone stiffness has been proposed to initiate and/or contribute to cartilage deterioration in OA. The purpose of this study was to characterize subchondral bone remodeling, cartilage damage, and osteophytosis during the disease progression in two models of surgically induced OA. Rat knee joints were subjected either to anterior cruciate ligament transection (ACLT) alone or in combination with resection of medial menisci (ACLT + MMx). Histopathological changes in the surgical joints were compared with sham at 1, 2, 4, 6, and 10 weeks post-surgery. Using a modified Mankin scoring system, we demonstrate that articular cartilage damage occurs within 2 weeks post-surgery in both surgical models. Detectable cartilage surface damage and proteoglycan loss were observed as early as 1 week post-surgery. These were followed by the increases in vascular invasion into cartilage, in loss of chondrocyte number and in cell clustering. Histomorphometric analysis revealed subchondral bone loss in both models within 2 weeks post-surgery followed by significant increases in subchondral bone volume relative to sham up to 10 weeks post-surgery. Incidence of osteophyte formation was optimally observed in ACLT joints at 10 weeks and in ACLT + MMx joints at 6 weeks post-surgery. In summary, the two surgically induced rat OA models share many characteristics seen in human and other animal models of OA, including progressive articular cartilage degradation, subchondral bone sclerosis, and osteophyte formation. Moreover, increased subchondral bone resorption is associated with early development of cartilage lesions, which precedes significant cartilage thinning and subchondral bone sclerosis. Together, these findings support a role for bone remodeling in OA pathogenesis and suggest that these rat models are suitable for evaluating bone

    Transplantation of aggregates of synovial mesenchymal stem cells (MSCs) enhanced meniscus regeneration in rats. Anatomy and biological properties of the meniscus depend on animal species. To apply this technique clinically, it is valuable to investigate the use of animals genetically close to humans. We investigated whether transplantation of aggregates of autologous synovial MSCs promoted meniscal regeneration in aged primates. Chynomolgus primates between 12 and 13 years old were used. After the anterior halves of the medial menisci in both knees were removed, an average of 14 aggregates consisting of 250,000 synovial MSCs were transplanted onto the meniscus defect. No aggregates were transplanted to the opposite knee for the control. Meniscus and articular cartilage were analyzed macroscopically, histologically, and by MRI T1rho mapping at 8 (n = 3) and 16 weeks (n = 4). The medial meniscus was larger and the modified Pauli's histological score for the regenerated meniscus was better in the MSC group than in the control group in each primate at 8 and 16 weeks. Mankin's score for the medial femoral condyle cartilage was better in the MSC group than in the control group in all primates at 16 weeks. T1rho value for both the regenerated meniscus and adjacent articular cartilage in the MSC group was closer to the normal meniscus than in the control group in all primates at 16 weeks. Transplantation of aggregates of autologous synovial MSCs promoted meniscus regeneration and delayed progression of degeneration of articular cartilage in aged primates.

    The Hartley guinea pig develops articular cartilage degeneration similar to that seen in idiopathic human osteoarthritis (OA). We investigated whether the application of pulsed low-intensity ultrasound (PLIUS) to the Hartley guinea pig joint would prevent or attenuate the progression of this degenerative process. Treatment of male Hartley guinea pigs was initiated at the onset of degeneration (8 weeks of age) to assess the ability of PLIUS to prevent OA, or at a later age (12 months) to assess the degree to which PLIUS acted to attenuate the progression of established disease. PLIUS (30 mW/cm(2)) was applied to stifle joints for 20 min/day over periods ranging from 3 to 10 months, with contralateral limbs serving as controls. Joint cartilage histology was graded according to a modified Mankin scale to evaluate treatment effect. Immunohistochemical staining for interleukin-1 receptor antagonist (IL-1ra), matrix metalloproteinase (MMP)-3, MMP-13, and transforming growth factor (TGF)-beta1 was performed on the cartilage to evaluate patterns of expression of these proteins. PLIUS did not fully prevent cartilage degeneration in the prevention groups, but diminished the severity of the disease, with the treated joints showing markedly decreased surface irregularities and a much smaller degree of loss of matrix staining as compared to controls. PLIUS also attenuated disease progression in the groups with established disease, although to a somewhat lesser extent as compared to the prevention groups. Immunohistochemical staining demonstrated a markedly decreased degree of TGF-beta1 production in the PLIUS-treated joints. This indicates less active endogenous repair, consistent with the marked reduction in cartilage degradation. PLIUS exhibits the ability to attenuate the progression of cartilage degeneration in an animal model of idiopathic human OA. The effect was greater in the treatment of early, rather than established, degeneration. Published by Elsevier Ltd.

  18. Altered but Not Silenced: How Shostakovich Retained His Voice as an Artist despite the Demands of a Dictator

    Hope R. Strayer

    2013-12-01

    Full Text Available Can music that is regulated and restrained by a dictator still be inspired? This question reveals ideology concerning how music should be created and valued. Does outside control restrict artistic integrity and autonomy? Not all composers have been free to write whatever their soul demands. People in authority have held power and control over artistic processes. Dmitri Shostakovich was a Russian composer whose work was subjected to the tastes of a tyrannical ruler and Communist party. Though Shostakovich did not compose in an environment that fostered musical exploration, his work should not be mourned but celebrated. Shostakovich was not a victim, but a victor of his music by the way he composed in the midst of the threat of denouncement. Though Shostakovich wrote music to follow the demands of others, the music was still his by the very fact that he created it; he brought it into existence and highlighted it with nuances of his being and personality as he produced each work. This research examines three critical pieces of Shostakovich’s canon to ascertain whether controlled art subjected to the whims, preferences, and objectives of others can still be inspired. Though a composer might be told what to say, it is he who chooses how to word a phrase. Shostakovich’s output, particularly the first symphony, his opera Lady Macbeth of the Mtsensk District, and fifth symphony exemplify that restrained and restricted music does not necessitate a sacrifice in artistic integrity; it can be inspired, celebrated, and worthy of study.

  19. The Coming Revolution of Peer Production and Revolutionary Cooperatives. A Response to Michel Bauwens, Vasilis Kostakis and Stefan Meretz

    Jakob Rigi

    2014-04-01

    Full Text Available This article agrees with Meretz (2014 that the peer producing cooperatives which are proposed by Bauwens & Kostakis (2014 will become parts and parcels of the capitalist economy. Further, it argues that the so called Peer Production Licenses (PPL, originally designed by Dmitry Kleiner (2010, which is the basis of their proposal is a rent seeking instrument. Contra Bauwens & Kostakis, it argues that, from the perspectives of both reform and revolution, GPL is profoundly anti-capitalist. The article critiques Meretz`s understanding of exchange and reciprocity, on the one hand, and his underestimation of GPL`s communist aspect, on the other. On the positive side, the article, explicating the communist nature of GPL-oriented peer production, speculates about the general contours of a society where peer production is the dominant mode of production. The technological basis of this society, the article suggests, will be digital copying and automation. Spatially, it will be based on localities that transcend the current division between the city and country, synthesising agriculture with industrial, affective and symbolic production. The rise of a globally unified revolutionary social struggle which adopts peer production as its platform is indispensible for the transformation of capitalism into such a society.  A global network of revolutionary peer producing cooperatives which break with market and reduce their relations to it to an absolutely unavoidable necessary minimum can be a significant component of this social struggle. The building of these revolutionary cooperatives requires a massive exodus from the city to the country.

    Full Text Available Background. Based on a long personal story of dealing with LGBTQ rights in Russia, the author reviews several transformations in the psychological approach and research to gender and sexual identity. The author describes his professional growth as a psychologist. First his interest was in child sex-role development and then transformed to prevention of sexual crimes, AIDS prevention and sexual education among adolescents. The author shows how his area of expertise in human sexuality brought him to professional ethics for psychologists. Discussion. In the second part of the article the author reviews changes in social attitudes towards same sex- relationships from their criminalization and medicalization to acceptance and respect. The author emphasizes the pioneering role of Professor Igor Kon in changes of mass attitudes towards sexuality and same sex relationships. The author sees Kon’s legacy in his statement that “As long as gays and lesbians are objects of bullying and discrimination, everybody who considers himself/herself as a thinking person must support LGBTQ people’s fight for their human rights.” At the end of this part of the article, the author describes a recent hate crime based in homophobia, and its victim, the talented St. Petersburg journalist, Dmitry Tsilikin. Tsilikin was involved in sex education in the 1990s and published a book about these issues. His murder was not considered by the court to be a hate crime against an LGBTQ person, despite enormous protest from progressive-minded people all over Russia. Conclusion. The author recommends the Russian Psychological Ethics Code as a way to help psychologists support and advocate for people regardless of sexual orientation or gender identity.

    Full Text Available The article examines st. Dimitry’s of Rostov contacts with Kiev and Chernigov in 1701–1709. Dimitry’s correspondence is vast, but addressees of the most of the known letters are Dmitry’s Moscow friend and Great Russian hierarchs. Problem of st. Dimitry’s contacts with his Little Russian acquaintances still remain obscure. This article deals with the information of st. Dimitry of Rostov correspondence with addressees in Kiev and Chernigov and the circumstances of Dimitry’s visit to Chernigov in 1704. In time of his episcopal service st. Dimitry exchanged letters with Josaph Krokowski, archimandrit of Kievan Lauras and future metropolitan of Kiev. Letters were sent with agents of both hierarchs. This correspondence was devoted to the publication of the “Lives of the Saints” in the Lavra’s typography. There are no evedencies of st. Dimitry writing letteres to members of Chernigov clergy in 1701–1709, although st. John Maximovich archbishop of Chernigov sent his new books to Dimitry of Rostov. However in february of 1704st. Dmitry undertook a journey to Chernigov that left almost no traces in sources. The main evidence is record of Pachomios of Roman, a Moldavian ascetic, about himself meeting Rostov metropolitan in Chernigov in 1704. This trip was an exeptional event and could be connected with the demise of Parthenios Neboza, metropolitan of Holmogory, who died suddenly on 2 january 1704 in Yaroslavl. Author concludes that Dimitry of Rostov in 1701–1709 was not isolated from his old friends and mantained his ties with educated clergy of Little Russia during the years of his Episcopal service in Moscow and Rostov.

    John Dalton first proposed the concept of atomic weights of the elements in the first decade of the nineteenth century. These atomic weights of the chemical elements were thought of as constants of nature, similar to the speed of light. Dmitri Mendeleev arranged the atomic weights of the elements in ascending order of value and used the systematic variation of their chemical properties to produce his Periodic Table of the Elements in 1869. Measurement of atomic weight values became an important chemical activity for a century and a half. Theodore Richards received a Noble Prize for his work in this area. In 1913, Fredrick Soddy found a species of radium, which had an atomic weight value of 228, compared to the familiar radium gas value of 226. Soddy coined the term 'isotope' (Greek for 'in the same place') to account for this second atomic weight value in the radium position of the Periodic Table. Both of these isotopes of radium are radioactive. Radioactive isotopes are energetically unstable and will decay (disintegrate) over time. The time it takes for one half of a sample of a given radioactive isotope to decay is the half-life of that isotope. In addition to having different atomic weight values, radium-226 and radium-228 also have different half-life values. Around the same time as Soddy's work, J.J. Thomson (discoverer of the electron) identified two stable (non-radioactive) isotopes of the same element, neon. Over the next 40 years, the majority of the known chemical elements were found to have two or more stable (or long-lived radioactive isotopes that contribute significantly to the determination of the atomic weights of the elements).

    MIV-711 is a highly potent and selective cathepsin K inhibitor. The current article summarizes the therapeutic effects of MIV-711 on joint pathology in rabbits subjected to anterior cruciate ligament transection (ACLT), and the prophylactic effects on joint pathology in dogs subjected to partial medial meniscectomy, two surgical models of osteoarthritis (OA). Starting 1 week after surgery, rabbits were dosed daily via oral gavage with either MIV-711 or vehicle (n = 7/group) for 7 weeks. The four treatment groups were: (1) sham + vehicle; (2) ACLT + vehicle; (3) ACLT + MIV-711, 30 µmol/kg and (4) ACLT + MIV-711, 100 µmol/kg. Subchondral bone and articular cartilage structures were assessed by µCT, histomorphometry, and scoring. Dogs subjected to partial medial meniscectomy received either MIV-711 (30 µmol/kg) or vehicle (n = 15/group) via oral gavage once daily, starting 1 day before meniscectomy, for 28 days. Cartilage degradation was assessed at the macroscopic and microscopic levels. The exposures of MIV-711 were assessed in both studies and biomarkers reflecting bone resorption (HP-1 in rabbits, CTX-I in dogs) and cartilage degradation (CTX-II) were measured. In ACLT rabbits, MIV-711 decreased HP-1 levels by up to 72% (p subchondral bone plate and reduced trabecular bone volume in the femur and tibia. These effects were reversed by MIV-711. ACLT resulted in cartilage thickening, which was attenuated by MIV-711. MIV-711 did not affect osteophyte formation or Mankin scores. In dogs, MIV-711 reduced CTX-I and CTX-II levels by 86% (p subchondral bone loss and partially attenuates cartilage pathology in two animal models of OA. These beneficial effects of MIV-711 on joint pathology are observed in conjunction with decreases in bone and cartilage biomarkers that have been shown to be clinically attainable in human. The data support the further development of MIV-711 for the treatment of OA.

The translational progress of this compound has been hindered by poor pharmacokinetics and toxicity. We sought to determine whether liposomal encapsulation of STS would enhance antitumor efficacy and reduce toxicity, thereby supporting the feasibility of further preclinical development. We developed a novel reverse pH gradient liposomal loading method for STS, with an optimal buffer type and drug-to-lipid ratio. Our approach produced 70% loading efficiency with good retention, and we provide, for the first time, an assessment of the in vivo antitumor activity of STS. A low intravenous dose (0.8 mg/kg inhibited U87 tumors in a murine flank model. Biodistribution showed preferential tumor accumulation, and body weight data, a sensitive index of STS toxicity, was unaffected by liposomal STS, but did decline with the free compound. In vitro experiments revealed that liposomal STS blocked Akt phosphorylation, induced poly(ADP-ribose polymerase cleavage, and produced cell death via apoptosis. This study provides a basis to explore further the feasibility of liposomally encapsulated STS, and potentially related compounds for the management of resistant solid tumors.Keywords: liposomes, staurosporine, glioblastoma, biodistribution, efficacy

    Vladimir Korobov of the Joint Institute for Nuclear Research at Dubna in Russia and Dmitri Bakalov of the Institute for Nuclear Research and Nuclear Energy in Sofia, Bulgaria, have made a theoretical breakthrough in interpreting the properties of antiprotonic helium atoms (helium atoms in which an electron has been replaced by an antiproton) in terms of the properties of the antiproton itself. Classic quantum mechanics suggests that when such a atom is highly excited, the orbiting antiproton should quickly decay, emitting visible photons as it goes. One crucial defect in this argument is its neglect of the force between the antiproton and the remaining electron. More detailed calculations suggest that the antiproton will not have time to decay in such fashion, or emit any photons. So it came as a shock in 1990 when a group lead by Toshimitsu Yamazaki of Tokyo University showed that about 3% of all antiprotonic helium atoms survive for several microseconds in spite of the antiproton/electron interactions. This metastability against annihilations appears to be connected with a delay in the ejection of a second electron, during which time the antiprotonic atom continues to live. Furthermore, the electron seems to reduce the atom's sensitivity to collisions. This was confirmed in 1993 when the Japanese group, now joined by several European colleagues, showed that antiprotonic helium could indeed be stimulated by a laser beam to make a quantum jump of about 2 eV, from an n=39 level to an n=38 level (N Morita et al. 1994 Phys. Rev. Lett. 72 1180). This result highlights the importance of the Korobov and Bakalov paper. Since the second electron is essential for this metastability, its small but non-negligible interaction energy with the antiproton must be taken into account in calculations of energy levels. (UK)

    Full Text Available Russia needs to fit into the international geopolitical and geo-economic landscape. The formation of this landscape is largely determined by alternating integration and disintegration cycles in the development of the world economy. The second global disintegration cycle that started in 2008 is expected to last 15—20 years. It will be followed by a new integration cycle, largely dependent on China (Pax Sinensis instead of Pax Americana. This change necessitates a number of steps: a significant strengthening of the Eastern vector in the development of Russia, the formation of the Moscow-Beijing-New Delhi triangle (Evgeny Primakov's idea as well as providing access of energy-intensive and water-intensive goods from East Siberia by railway to the Chinese and Indian markets. Russia has expressed its interest in the construction of a railway from China to India. It will allow Russia to reduce transportation costs and use a potentially heavy transit traffic for the modernization of the Transsibirian railway. These steps could radically change the role of the Baltic exclave of Russia: from being a ‘window to Europe’ the region is to turn into the westernmost point of a infrastructure axis extending from east to west. The creation of such an axis, combined with a sharp fall in transportation costs will facilitate the access of energy-intensive and water-intensive goods from the Urals and Siberia to the Asian and European markets. The Kaliningrad region is increasingly taking on business facilitating functions, which used to be performed by the Soviet Baltic republics in the past. The region can play a more important role in the formation of Eurasia stretching from Shanghai to St. Petersburg (according to Dmitry Trenin, instead of the Europe from Lisbon to Vladivostok.

Cost inputs were derived from publicly available databases or from the published literature. Expert opinion was only used if no other source was available. Efficacy data from two randomized clinical trials were used. The time horizon in the health economic model was lifetime. Efficacy and costs were discounted by 3.5%. All main model parameters were tested in deterministic and probabilistic sensitivity analyses.Results: Mean incremental savings to society per patient ranged from €2277 in Italy to €4461 in Germany. The results were most sensitive to the change in proportion of patients working full-time and the proportion of patients who were able to return to work.Conclusion: This analysis shows that bevacizumab-based treatment in non-small-cell lung cancer is associated with more savings to society compared to standard chemotherapy in terms of increased productivity and decreased social benefits paid to patients who are able to work in France, Germany, Italy, and Spain.Keywords: non-small-cell lung cancer, bevacizumab, chemotherapy, economic model, France, Germany, Italy, Spain

  8. IUPAC Periodic Table of Isotopes for the Educational Community

    John Dalton first proposed the concept of atomic weights of the elements in the first decade of the nineteenth century. These atomic weights of the chemical elements were thought of as constants of nature, similar to the speed of light. Dmitri Mendeleev arranged the atomic weights of the elements in ascending order of value and used the systematic variation of their chemical properties to produce his Periodic Table of the Elements in 1869. Measurement of atomic weight values became an important chemical activity for a century and a half. Theodore Richards received a Noble Prize for his work in this area. In 1913, Fredrick Soddy found a species of radium, which had an atomic weight value of 228, compared to the familiar radium gas value of 226. Soddy coined the term 'isotope' (Greek for 'in the same place') to account for this second atomic weight value in the radium position of the Periodic Table. Both of these isotopes of radium are radioactive. Radioactive isotopes are energetically unstable and will decay (disintegrate) over time. The time it takes for one half of a sample of a given radioactive isotope to decay is the half-life of that isotope. In addition to having different atomic weight values, radium-226 and radium-228 also have different half-life values. Around the same time as Soddy's work, J.J. Thomson (discoverer of the electron) identified two stable (non-radioactive) isotopes of the same element, neon. Over the next 40 years, the majority of the known chemical elements were found to have two or more stable (or long-lived radioactive isotopes that contribute significantly to the determination of the atomic weights of the elements).

    Full Text Available Vers 1770, la campagne anti-russe du gouvernement français tend à dégrader l’image de la Russie, ce qui lèse gravement ses intérêts, notamment quand elle doit emprunter pour financer la guerre avec la Turquie. Aussi le prince Dmitri Alexeevitch Golitsyn, ministre plénipotentiaire à La Haye, se montre-t-il alors très actif sur ce terrain. Sa correspondance avec Pétersbourg témoigne de ses efforts, aux effets inégaux, pour influer sur les informations diffusées par quelques journaux : principalement le Courrier du Bas-Rhin, publié par Jean Manzon à Trèves, sous contrôle prussien, et dans une moindre mesure les deux Gazettes des Deux-Ponts, l’une politique, l’autre littéraire. Le journaliste de Trèves, qui trouve son intérêt à prendre le parti de la Russie, met en œuvre en sa faveur un discours journalistique abondant et parfois très élaboré. Cependant, la ligne du journal subit des fluctuations sensibles, selon l’évolution de la situation et à la suite de diverses interventions, dont celles du roi de Prusse et d’autre part de Stanislas-Auguste, qui pensionne un temps le journaliste. La Gazette des deux Ponts pratique l’information orientée avec plus de finesse, et, comme la gazette littéraire, accorde une large place à la matière russe : mais sur le plan politique, son traitement reste le plus souvent sous influence française et répond rarement aux vœux de D. A. Golitsyn.

This study also evaluated the synergistic effect of a novel compound PBS-44, an α-galactosylceramide analog, in boosting the immune response induced by our nanovaccine. The nanovaccine was prepared by encapsulating ovalbumin (ova and an adjuvant within the poly(lactic-co-glycolic acid nanoparticles. Quantitative analysis of our study data showed that the encapsulated vaccine was physically and biologically stable; the core content of our nanovaccine was found to be released steadily and slowly, and nearly 90% of the core content was slowly released over the course of 25 days. The in vivo immunization studies exhibited that the nanovaccine induced stronger and longer immune responses compared to its soluble counterpart. Similarly, intranasal inhalation of the nanovaccine induced more robust antigen-specific CD8+ T cell response than intraperitoneal injection of nanovaccine

In the study reported here, we designed and developed a lipid-modified dextran-based polymeric nanoparticle platform for encapsulation of miRs, and determined the efficiency and efficacy of delivering miR-199a-3p into osteosarcoma cells. In addition, another potent miR, let-7a, which also displayed tumor suppressive ability, was selected as a candidate miR for evaluation. Fluorescence microscopy studies and real-time polymerase chain reaction results showed that dextran nanoparticles could deliver both miR-199a-3p and let-7a into osteosarcoma cell lines (KHOS and U-2OS successfully. Western blotting analysis and 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide (MTT assays demonstrated that dextran nanoparticles loaded with miRs could efficiently downregulate the expression of target proteins and effectively inhibit the growth and proliferation of osteosarcoma cells.

    An ovine model of osteoarthritis (OA) induced by bilateral lateral meniscectomy (BLM) was used to evaluate in vivo effects of the slow acting antiarthritic drug diacerein (DIA) on degenerative changes in cartilage and subchondral bone of the operated joints. Twenty of 30 adult age matched Merino wethers were subjected to BLM in the knee joints and the remainder served as non-operated controls (NOC). Half of the BLM group (n = 10) were given DIA (25 mg/kg orally) daily for 3 mo, then 50 mg/kg daily for a further 6 mo. The remainder of the meniscectomized (MEN) group served as OA controls. Five DIA, 5 MEN, and 5 NOC animals were sacrificed at 3 mo and the remainder at 9 mo postsurgery. One knee joint of each animal was used for bone mineral density (BMD) studies. Osteochondral slabs from the lateral femoral condyle and lateral tibial plateau were cut from the contralateral joint and were processed for histological and histomorphometric examination to assess the cartilage and subchondral bone changes. No significant difference was observed in the modified Mankin scores for cartilage from the DIA and MEN groups at 3 or 9 mo. However, in animals treated with DIA, the thickness of cartilage (p = 0.05) and subchondral bone (p = 0.05) in the lesion (middle) zone of the lateral tibial plateau were decreased relative to the corresponding zone of the MEN group at 3 mo (p = 0.05). At 9 mo subchondral bone thickness in this zone remained the same as NOC but BMD, which included both subchondral and trabecular bone, was significantly increased relative to the NOC group (p = 0.01). In contrast, the subchondral bone thickness of the outer zone of lateral tibial plateau and lateral femoral condyle of both MEN and DIA groups increased after 9 mo, while BMD remained the same as in the NOC. DIA treatment of meniscectomized animals mediated selective responses of cartilage and subchondral bone to the altered mechanical stresses induced across the joints by this procedure. While

    To develop a radiographic score for assessment of hand osteoarthritis (OA) that is based on histopathological alterations of the distal (DIP) and proximal (PIP) interphalangeal joints. DIP and PIP joints were obtained from corpses (n=40). Plain radiographies of these joints were taken. Joint samples were prepared for histological analysis; cartilage damage was graded according to the Mankin scoring system. A 2×2 Fisher's exact test was applied to define those radiographic features most likely to be associated with histological alterations. Receiver operating characteristic curves were analysed to determine radiographic thresholds. Intraclass correlation coefficients (ICC) estimated intra- and inter-reader variability. Spearman's correlation was applied to examine the relationship between our score and histopathological changes. Differences between groups were determined by a Student's t test. The Interphalangeal Osteoarthritis Radiographic Simplified (iOARS) score is presented. The score is based on histopathological changes of DIP and PIP joints and follows a simple dichotomy whether OA is present or not. The iOARS score relies on three equally ranked radiographic features (osteophytes, joint space narrowing and subchondral sclerosis). For both DIP and PIP joints, the presence of one x-ray features reflects interphalangeal OA. Sensitivity and specificity for DIP joints were 92.3% and 90.9%, respectively, and 75% and 100% for PIP joints. All readers were able to reproduce their own readings in DIP and PIP joints after 4 weeks. The overall agreement between the three readers was good; ICCs ranged from 0.945 to 0.586. Additionally, outcomes of the iOARS score in a hand OA cohort revealed a higher prevalence of interphalangeal joint OA compared with the Kellgren and Lawrence score. The iOARS score is uniquely based on histopathological alterations of the interphalangeal joints in order to reliably determine OA of the DIP and PIP joints radiographically. Its high

Although patient-controlled devices are frequently used in patients ≥6 years of age, alternative modes of analgesic delivery are needed in infants.Objective: To examine the safety and efficacy of nurse-controlled analgesia (NCA in neonates less than 1 year of age.Methods: Data from patients <1 year of age receiving NCA as ordered by the Acute Pain Service at our institution were collected over a 5-year period and reviewed retrospectively. The primary outcomes were activation of the institution’s Rapid Response Team (RRT or Code Blue, signifying severe adverse events. Pain score after NCA initiation was a secondary outcome.Results: Among 338 girls and 431 boys, the most common opioid used for NCA was fentanyl, followed by morphine and hydromorphone. There were 39 (5% cases involving RRT or Code Blue activation, of which only one (Code Blue was activated due to a complication of NCA (apnea. Multivariable logistic regression demonstrated morphine NCA to be associated with greater odds of RRT activation (OR=3.29, 95% CI=1.35, 8.03, P=0.009 compared to fentanyl NCA. There were no statistically significant differences in pain scores after NCA initiation across NCA agents.Conclusion: NCA is safe in neonates and infants, with comparable efficacy demonstrated for the three agents used. The elevated incidence of RRT activation in patients receiving morphine suggests caution in its use and consideration of alternative agents in this population.

We hypothesized that the antimicrobial peptide (AMP complex of the host’s immune system can be used for this purpose and examined the assumption on model biofilms. Methods: FLIP7, the AMP complex of the blowfly Calliphora vicina containing a combination of defensins, cecropins, diptericins and proline-rich peptides was isolated from the hemolymph of bacteria-challenged maggots. The complex interaction with antibiotics of various classes was studied in biofilm and planktonic cultures of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Acinetobacter baumannii by the checkerboard method using trimethyl tetrazolium chloride cell viability and crystal violet biofilm eradication assays supplemented with microscopic analysis. Results: We found that FLIP7 demonstrated: high synergy (fractional inhibitory concentration index <0.25 with meropenem, amikacin, kanamycin, ampicillin, vancomycin and cefotaxime; synergy with clindamycin, erythromycin and chloramphenicol; additive interaction with oxacillin, tetracycline, ciprofloxacin and gentamicin; and no interaction with polymyxin B. The interaction in planktonic cell models was significantly weaker than in biofilms of the same strains. The analysis of the dose–effect curves pointed to persister cells as a likely target of FLIP7 synergistic effect. The biofilm eradication assay showed that the effect also caused total destruction of S. aureus and E. coli biofilm materials. The effect allowed reducing the effective anti-biofilm concentration of the antibiotic to a level well below the one clinically achievable (2–3 orders of magnitude in

We compared perioperative outcomes of combining dental surgical procedures with tonsillectomy during one anesthetic vs separate encounters. Methods: We classified elective tonsillectomy ± adenoidectomy and restorative dentistry as combined (group C or separate (group S. Outcomes included anesthesia time, recovery duration, the need for overnight hospital stay, and postoperative complications. Results: Patients aged 4±1 years underwent tonsillectomy and dental surgery in combination (n=7 or separately (n=27. No differences were noted in total anesthesia time (C: median: 150, interquartile range [IQR]: 99, 165 vs S: median: 109, IQR: 92, 132; 95% CI of difference in median: –58, +10 minutes; P=0.115 and total recovery time (C: median: 54, IQR: 40, 108 vs S: median: 72, IQR: 58, 109; 95% CI of difference in median: –16, +48 minutes; P=0.307. The need for overnight stay (C: 4 of 7, S: 20 of 27; P=0.394 did not differ between the groups. No postoperative complications were noted in either group. Conclusion: These preliminary data support the potential feasibility of combining dental procedures with tonsillectomy during a single anesthetic encounter. Such care may not only reduce costs but also limit parental work absences and increase convenience for patient families. When compared with procedures performed separately, combined procedures did not result in increased morbidity or

    Dorianna Twersky, Editor Emerita of Nuclear Fusion, passed away on 22 January 2010. Dorianna was Editor of Nuclear Fusion for nearly two decades, from 1967 to 1985. During her tenure, the journal underwent an impressive development. In 1967 Nuclear Fusion was a quarterly with 300 pages published each year, by 1978 it had become a monthly journal. Reflecting the developments in the field, it had evolved from a general plasma physics journal to one that was far more fusion relevant. Dorianna ensured that Nuclear Fusion had a strong peer review system and that effective journal policies were developed and adhered to. Dorianna drove the success of the journal. Her dynamic personality and commitment to the international fusion community underpinned that success. She had a well deserved reputation for toughness and for critical and intuitive thinking. Perhaps her most valuable trait was her persuasiveness and ability to motivate people to help with the journal and contribute to its development. She was able to inspire a sense of dedication and enthusiasm in the people she worked with and was highly respected. Dorianna Twersky will be greatly missed. Four of the prominent scientists who served on the Nuclear Fusion Board of Editors during Dorianna's Editorship have written a few lines in her memory: Professor Dmitri Ryutov, Professor Folker Engelmann, Professor Jim Callen and Professor Karl Lackner. "Dorianna Twersky was one of the best journal editors who I have met during my half-century in physics and plasma physics.

Sometimes she would add a handwritten joke, or a small cartoon at the corner of her letter. Dorianna spoke perfect Russian. That was of significant help to a

We surveyed caregivers of patients undergoing surgery to determine their knowledge and acceptance of hypnotherapy, acupuncture, and music therapy as alternatives to standard medication in the perioperative period. Materials and methods: An anonymous, 12-question survey was administered to caregivers of children undergoing procedures under general anesthesia. Caregivers reported their knowledge about hypnotherapy, music therapy, and acupuncture and interest in one of these methods during the perioperative period. CAM acceptance was defined as interest in one or more CAM methods.Results: Data from 164 caregivers were analyzed. The majority of caregivers were 20–40 years of age (68% and mothers of the patient (82%. Caregivers were most familiar with acupuncture (70%, followed by music therapy (60% and hypnotherapy (38%. Overall CAM acceptance was 51%. The acceptance of specific CAM modalities was highest for music therapy (50%, followed by hypnotherapy (17% and acupuncture (13%. In multivariable logistic regression, familiarity with music therapy was associated with greater odds of CAM acceptance (odds ratio=3.36; 95% CI: 1.46, 7.74; P=0.004.Conclusion: Overall CAM acceptance among caregivers of children

This is primarily due to a lack of successful methods that can prevent NP uptake by the reticuloendothelial system, especially the liver and kidney, and deliver sufficient quantities of intravenously injected NPs to the tumor site. Histological evaluation of photothermal therapy-induced tumor regression is also neglected in the current literature. This report demonstrates and histologically evaluates the in vivo potential of NIR photothermal therapy by circumventing the challenges of intravenous NP delivery and tumor targeting found in other photothermal therapy studies.Methods: Subcutaneous Cal 27 squamous cell carcinoma xenografts received photothermal nanotherapy treatments, radial injections of polyethylene glycol (PEG-ylated gold nanorods and one NIR 785 nm laser irradiation for 10 minutes at 9.5 W/cm2. Tumor response was measured for 10–15 days, gross changes in tumor size were evaluated, and the remaining tumors or scar tissues were excised and histologically analyzed.Results: The single treatment of intratumoral nanorod injections followed by a 10 minute NIR laser treatment also known as photothermal nanotherapy, resulted in ~100% tumor regression in ~90% of treated tumors, which was statistically significant in a

  8. New vision of magnetic tunnelling

    Energy Technology Data Exchange (ETDEWEB)

    Friedman, Jonathan R. [Amherst College, Amhurst, MA (United States)

    2002-01-01

    Recent experiments support the idea that crystal defects may be responsible for the quantum tunnelling of magnetic moments in molecular magnets at low temperatures. The magnetic moment of a typical bar magnet will never spontaneously reverse direction. However, thermal fluctuations can flip the moment of a magnetic particle just a few nanometres across. The particle can be cooled to nearly absolute zero to suppress this process, but the moment may still find a way to reverse via quantum tunnelling. Quantum tunnelling of magnetization has been the subject of decades of research. Until a few years ago, however, there had only been circumstantial evidence for the phenomenon. This is because most systems of small magnetic particles are hard to characterize - the particles have a variety of shapes, sizes and other properties, making it difficult to compare data with theory. Some real progress was made a few years ago through research into high-spin single-molecule magnets. With dimensions of about a nanometre, these magnets are usually composed of a magnetic core that is surrounded by organic complexes. When they crystallize into a regular lattice, the organic ions keep neighbouring magnets well separated so that they interact only weakly. Ideally all the molecules are identical because they have been built chemically, which means that they can be characterized precisely and that any data can be analysed quantitatively. The most studied of these molecules is manganese-12 acetate (Mn{sub 12}). Within each molecule, the spins of the eight Mn{sup 3+} ions (each with S=2) are antiparallel to the spins of the four Mn{sup 4+} ions (each with S=3/2), giving Mn{sub 12} a total spin of S=10. Or, to put it another way, the magnetic moment of Mn{sub 12} is 20 times larger than that of the electron. Now Eugene Chudnovsky of Lehman College in New York and Dmitry Garanin of the University of Mainz in Germany have suggested a new mechanism for producing tunnelling in Mn{sub 12

  9. The Russian Orthodox Church and atheism

    Full Text Available After the collapse of the Soviet Union in 1991, the religious tide in Russia has been quick to rise. During the Soviet era, religion – particularly Orthodox Christianity and Islam – was considered to be one of the ‘enemies of the people’. Since the late 1990s however, Russian politicians at all levels of the power structure have associated themselves either with the Orthodox, or on some occasions with the Muslim, clergy. The present state of affairs in the relations between religion and the state are well illustrated by the cordial liaison of the late Patriarch Aleksii II with President Vladimir Putin and the equally warm involvement of President Dmitry Medvedev, and his wife Svetlana Medvedeva, with the new Patriarch Kirill, who was elected in January 2009. Some have even argued that ‘today’ (in 2004 the Church and state are so extensively intertwined that one can no longer consider Russia to be a secular state. Polls seem to support the claim. While in 1990 only 24 per cent of Russians identified themselves as Orthodox, in the sense that they felt themselves to be Russians as well, in 2008 the number was 73 per cent. However, less than 10 per cent, and in Moscow perhaps only 2 per cent do actually live out their religiosity.Why did Russia turn towards religion? Is religion chosen in an attempt to legitimise power, or in order to consolidate political rule after atheist-communist failure? My guess is that the answer to both is affirmative. Moreover, whatever the personal convictions of individual Russians, including politicians, religious, mainly Orthodox Christian, rhetoric and rituals are used to make a definitive break with the communist past and to create, or re-create, a Greater Russia (see Simons 2009. In such an ideological climate, atheism has little chance of thriving, whereas there is a sort of ‘social demand’ for its critique.I therefore focus on what the Russian Orthodox Church (ROC has had to say about atheism and

Modified Mankin scores were significantly lower in the SAP and SAP-MSC groups than in controls (P=0.001 and 0.013. Although not statistically significant, synovial inflammation scores were lower in the SAP (1.3±0.3 and SAP-MSC (1.3±0.2 groups than in controls (2.6±0.2. However, neither the cytokine level nor the behavioral score was significantly different between groups.Conclusion: Injection of SAP-MSC hydrogels showed evidence of chondroprotection, as measured by the histologic grading and decreased expression of biochemical markers of inflammation and apoptosis. It also lowered subchondral bone mineral density, which can be increased by OA. This suggests that the SAP-MSC complex may have clinical potential to inhibit OA progression.Keywords: self-assembled peptide, mesenchymal stem cell, osteoarthritis, apoptosis, chondrogenesis

    Previous studies have demonstrated that optical coherence tomography (OCT) could be used to delineate alterations in the microstructure of cartilage, and have suggested that changes in the polarization state of light as detected by OCT could provide information on the birefringence properties of articular cartilage as influenced by disease. In this study we have used both OCT and polarization sensitive optical coherence tomography (PS-OCT) technologies to evaluate normal and abnormal bovine articular cartilage according to established structural, organizational, and birefringent characteristics of degenerative joint disease (DJD) in order to determine if this technology can be used to differentiate various stages of DJD as a minimally invasive imaging tool. Fresh bovine femoral-tibial joints were obtained from an abattoir, and 45 cartilage specimens were harvested from 8 tibial plateaus. Whole ex vivo specimens of normal and degenerative articular cartilage were imaged by both OCT and PS-OCT, then fixed and processed for histological evaluation. OCT/PS-OCT images and corresponding histology sections of each specimen were scored according to a modified Mankin structural grading scale and compared. OCT and PS-OCT imaging allowed structural evaluation of intact articular cartilage along a 6 mm surface length to a depth of 2 mm with a transverse resolution of 12 microm and an axial resolution of 10 microm. The OCT and PS-OCT images demonstrated characteristic alterations in the structure of articular cartilage with a high correlation to histological evaluation (kappa = 0.776). The OCT images were able to demonstrate early to advanced structural changes of articular cartilage while the optical phase retardation images obtained by PS-OCT imaging were able to discriminate areas where disorganization of the cartilage matrix was present, however, these characteristics are much different than those reported where OCT images alone were used to characterize tissue

    An accepted principle of disaster risk reduction is that all stakeholders should be engaged in the process. For extreme geophysical events, this almost always means stakeholders in more than one country. Even when the direct impacts on the ground from violent shaking or explosive eruptions are confined to a single country, effects to lives and property may be carried thousands of kilometers from the event source by tsunamis or ash clouds, respectively. The formation of G-EVER recognizes the need for neighbors to join together on disaster risk reduction. There is much to be gained by sharing real-time monitoring data and databases on past extreme events, mapping risks seamlessly across borders, and establishing best practices through sharing of experiences. Each extreme event is a learning opportunity, and the recent lessons have been particularly painful. Our science, while progressing, is still inadequate both in content and in application. There has also been lack of recognition that the "worst case" is indeed possible. Among the various collaborations needed to reduce disaster risk is bilateral collaboration, because borders are obstacles and exist between two countries with rules that have been determined by those countries. Borders are used by all countries for protection of national and economic security. They restrict flow of people, equipment, and information, but not seismic waves, tsunamis, and ash. Even the relatively minor event of sea ice arriving early in Nome, Alaska last fall involved both Russia and the U.S. in a relief effort to bring fuel. It is the responsibility of natural hazard scientists and crisis managers to work together across borders, and where necessary make the case to their governments for sharing of data and information based on an expanded view of national security. The Bilateral Presidential Commission initiated by U.S. President Barrack Obama and Russian President Dmitry Medvedev has provided a framework in which to expand

Increasing the local anesthetic concentration in peripheral nerve blockade for adults undergoing orthopedic surgery has been shown to be beneficial, increasing block success rate, and providing a longer duration of analgesia. The effect of increasing the concentration of local anesthetic in extremity blocks in children remains largely unexplored.Methods: We retrospectively evaluated the effectiveness of FNB using three concentrations of local anesthetic (ropivacaine 0.2%, bupivacaine 0.25%, and ropivacaine 0.5% in children and adolescents undergoing arthroscopic knee surgery. The primary outcome evaluated was postoperative opioid consumption before discharge. Secondary outcomes included post-anesthesia care unit (PACU and hospital discharge times, first pain score in PACU, and the incidence of adverse events.Results: Two hundred and sixty-nine children and adolescents who received a FNB for arthroscopic knee surgery from January 2010 to December 2013 were included for analysis.

I. Blokhintsev. D. I. Blokhintsev had the special, original point of view on spiritual bases of scientific creativity that was directly reflected in his research and pedagogical activity.There are two fundamental aspects of pedagogics. On the one hand, it is the science possessing own specific laws and methods. On the other hand, the pedagogics is an art which methods, unlike scientific methodologies, can’t be acquired by formal and logical schemes. They are broadcast from one personality to another in direct communication. Thus possibly the «correspondence» assimilation of methods of outstanding teachers is inefficient as a rule. Not enough attention in the press is paid to this informal aspect of pedagogics in the view of difficulty of its description and analysis. The discussed D. I. Blokhintsev’s heritage is valuable from positions of the characteristic of pedagogics as arts of creative skill transfer. At first sight, it can seem paradoxical that this part of pedagogics is considered in connection with work in the field of the Quantum Field Theory and Cosmology – one of the most formalized fields of Theoretical Physics. However, the science, as well as pedagogics, considering it from top-level creativity, is becoming some kind of art too.One more important direction of work of D. I.

This mix of prose and poetry is also typical of the novel Petersburg. In the Dramatic Symphony Bely was targeting groups of mystics operating in the early 1900’s in Moscow and Saint Petersburg. He openly mentions or covertly alludes to actual protagonists of the literary, artistic and philosophical Russian society: Vladimir Solovyov (1853-1900, Dmitry Merezhkovsky (1865-1941 and others. Strictly autobiographical themes are presented in form of grotesque and hyperbolic images, alternating with moments of great lyrical tension. The «musical meaning» is also linked to the particular conception of time through which the plot of Bely’s Symphony is developed. At the beginning, a whole day passes by very slowly; then time speeds up and the plot goes through several months and seasons. At the end of the work we are back to where we started, like in a dramatic cycle. This method is well summarized in one of the leitmotive of the work: «And the time flowed without stopping, and the passage of time reflected the Eternity misty».

The length scales of most energetic dynamic features in both ocean and atmosphere are defined by the Rossby radius of deformation, which is about 1000 km (a typical size of a cyclone) in the atmosphere while only 10-20 km (a size of a mesoscale eddy) in a shallow sea. However sub-mesoscale atmospheric patterns such as patchiness in the cloud cover could result in smaller scale variations of both the wind and solar radiation hence creating a direct link of these smaller atmospheric features with the ocean mesoscale variability. The simulation has been performed using a version of POLCOMS numerical model (Enriquez et al, 2005). Tidal boundary conditions were taken from the Oregon State University European Shelf Tidal Model (Egbert et al, 2010) and the temperature/ salinity initial fields and boundary conditions were taken from the World Ocean Database (Boyer et al, 2004).

    metric tensor components. The first two chapters of this book are devoted to some basic ideas: in the introductory chapter 1 the authors discuss the concept of integrability, comparing the integrability of the vacuum Ernst equation with the integrability of nonlinear equations of Korteweg-de Vries (KdV) type, while in chapter 2 they describe various circumstances in which the vacuum Ernst equation has been determined to be relevant, not only in connection with gravitation but also, for example, in the construction of solutions of the self-dual Yang-Mills equations. It is also in this chapter that one of several equivalent linear systems for the Ernst equation is described. The next two chapters are devoted to Dmitry Korotkin's concept of algebro-geometric solutions of a linear system: in chapter 3 the structure of such solutions of the vacuum Ernst equation, which involve Riemann theta functions of hyperelliptic algebraic curves of any genus, is contrasted with the periodic structure of such solutions of the KdV equation. How such solutions can be obtained, for example, by solving a matrix Riemann-Hilbert problem and how the metric tensor of the associated spacetime can be evaluated is described in detail. In chapter 4 the asymptotic behaviour and the similarity structure of the general algebro-geometric solutions of the Ernst equation are described, and the relationship of such solutions to the perhaps more familiar multi-soliton solutions is discussed. The next three chapters are based upon the authors' own published research: in chapter 5 it is shown that a problem involving counter-rotating infinitely thin disks of matter can be solved in terms of genus two Riemann theta functions, while in chapter 6 the authors describe numerical methods that facilitate the construction of such solutions, and in chapter 7 three-dimensional graphs are displayed that depict all metrical fields of the associated spacetime. Finally, in chapter 8, the difficulties associated with

    nanometer scale. This special section contains interesting papers on graphene, h-BN and related 'honeycomb' compounds on solid surfaces, which are currently in development. Interfacial interaction strongly modifies the electronic and atomic structures of these overlayer systems and substrate surfaces. In addition, one can recognize a variety of growth phenomena by changing the surface and growth conditions, which are promising as regards fabricating those noble nanosystems. We have great pleasure in acknowledging the enthusiastic response and participation of our invited authors and their diligent preparation of the manuscripts.

    Christophe Peeters, Deputy Mayor of the City of Ghent, was followed by a reception in the historical "Pacificatiezaal" of the City Hall. On Wednesday afternoon the participants had the opportunity to take a guided tour through medieval Ghent, admiring its wide range of monuments. The tour was followed by a much-appreciated boat trip exploring the canals and rivers of Ghent, all in sunny weather. On Thursday evening the conference banquet was held in the "Brasserie HA". Located in the Handelsbeurs Ghent. In the majestic banquet hall, the participants were not only treated to an exclusive dinner, but also to some fine piano music by Dmitry Gal'tsov and Richard Kerner. The conference was sponsored by: American Institute of Physics (AIP Publishing), Clay Mathematics Institute, Clifford Research Group - Faculty of Engineering and Architecture (Ghent Unviversity), Elsevier, Faculty of Sciences (Ghent University), Fonds de la Recherche Scientifique (FNRS), Foundation Compositio Mathematica, FWO Research Foundation - Flanders, International Association of Mathematical Physics, International Solvay Institutes, International Union of Pure and Applied Physics, National Science Foundation (USA) and Springer Birkhäuser. We would like to thank all our sponsors for their generous support. It took more than two years to organise a conference of such a size and importance. We express our gratitude to the International Advisory Committee for its help in selecting the plenary speakers and to the external members of the Organising Committee for their helpful suggestions and advice. We thank Wouter Dewolf for his devoted secretarial, administrative and organisational work and Vera Vanden Driessche for arranging the "Accompanying persons' programme". Finally, a big 'thank you' to all the local people (administrative and technical staff, research assistants and research students) for their devoted and tireless work in preparing and running the conference.

    scenes an enormous amount of work is required to make a large conference go smoothly. First I thank Cheryl Zidel for her tireless efforts as organizing committee liaison and posters chair and, in general, handling all of my end of the program and keeping me calm. I also thank Gail Pieper for her work in editing the proceedings, Beth Cerny Patino for her work on the Organizing Committee website and electronic theater, and Ken Raffenetti for his work in keeping that website working. Jon Bashor and John Hules did an excellent job in handling conference communications. I thank Caitlin Youngquist for the striking graphic design; Dan Fay for tutorials arrangements; and Lynn Dory, Suzanne Stevenson, Sarah Pebelske and Sarah Zidel for on-site registration and conference support. We all owe Yeen Mankin an extra-special thanks for choosing the hotel, handling contracts, arranging menus, securing venues, and reassuring the chair that everything was under control. We are pleased to have obtained corporate sponsorship from Cray, IBM, Intel, HP, and SiCortex. I thank all the speakers and panel presenters. I also thank the former conference chairs Tony Metzzacappa, Bill Tang, and David Keyes, who were never far away for advice and encouragement. Finally, I offer my thanks to Michael Strayer, without whose leadership, vision, and persistence the SciDAC program would not have come into being and flourished. I am honored to be part of his program and his friend. Rick Stevens Seattle, Washington July 18, 2008
