“In this contribution, we report and discuss the physical meaning of pulse current measurements carried out on coated conductors (CCs) consisting of a superconducting YBCO film deposited on a Hastelloy substrate and coated with a thin metallic layer. The high current (up to 1000 A) and short duration pulses have allowed us to determine the current-voltage characteristics of two different samples in a situation near that of zero injected energy and therefore remove the bias resulting from the temperature rise during the measurement. The characteristics PD173074 order obtained show a flux creep region and two linear regimes. The first linear regime is the flux flow regime. In this regime, we show that there is a constant vortex velocity that depends on the metal film resistivity. The

second linear regime is also a vortex regime, but its precise nature is less clear. We propose models describing both linear regimes, in agreement with the measurements. Finally, we discuss the consequences of these results for the applications of CCs in devices for power systems, especially fault current limiters and power transmission cables.

“This is a cross-sectional study to assess the prevalence and causes of anemia in the primary Sjogren’s Kinase Inhibitor Library concentration syndrome (pSS). One hundred and thirty-two consecutive

patients with pSS were enrolled into the study. Standard hematological and immunological tests and examination of bone marrow were performed. Anemia occurred in 45 (34.1%) patients. The causes of anemia included anemia of chronic disease (69%), autoimmune hemolytic anemia (AIHA, 18%), iron deficiency anemia (9%) and other causes (4%), of which AIHA caused the most severe anemia. The prevalence of ANA, anti-Ro/SSA, and anti-La/SSB was much higher in patients with anemia than those without anemia. Anticardiolipin antibodies were most commonly detected in AIHA; the prevalence of IgG and hypocomplementemia in AIHA was much higher in patients without anemia. Abnormal bone marrow changes were observed in two cases with anemia, one with morphological changes in the myeloid, megakaryocytic, and erythroid lineages and one with hypocellularity in the erythroid lineage.

“In the present work we have studied the effect of 190 MeV Ag ion irradiation on the structural, electrical, and magnetic properties of LaFe(1-x)Ni(x)O(3) (x = 0.3 and 0.4) thin films. The films were grown on LaAlO(3) < 001 > oriented substrates using pulsed laser deposition technique. The pristine and irradiated samples were investigated using x-ray diffraction, temperature dependent resistivity, and magnetic measurements. The x-ray diffraction patterns of the irradiated films show that the lattice of the composition strain relaxed with enhanced c-axis orientation. The temperature

dependence of the resistivity indicates that all the films (pristine and irradiated) exhibit semiconducting behavior for entire studied temperature range (80-300 K). The pristine and irradiated samples show the activated variable see more range hopping behavior throughout the studied temperature range. The magnetization hysteresis measurements show ferromagnetic behavior at 300 K for all samples. The results are explained on the basis of the close interplay between the electrical and the magnetic

properties. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3400036]“
“Fibrous membranes of cellulose acetate (CA), poly(vinyl pyrrolidone) (PVP) and composite membranes of these polymers, were obtained by the electrospinning method. Using systematic CT99021 method, the optimal conditions for preparation of fibrous membranes were found. Both CA and PVP a concentration of 8% weight was found. The CA was dissolved in a acetone:- water solution, volume ratio 80 : 20 and the PVP is dissolved in ethanol:water solution, ratio volume 85 : 15. The flow rate for both polymers was 1.5 mL h(-1). The same applied voltage value and the distance between the needle and collection plate were for polymer both, 15 kV and 15 cm respectively. The morphology of fibrous membranes and composite membranes were evaluated by scanning electron microscopy (SEM). The CA fibers showed ribon morphology, while the PVP fibers were cilindric, in both cases with diameters in the micrometer range. Thermogravimetric analysis showed that CA had a complete degradation to 445 degrees C, while the fibrous membranes PVP required a value of temperature for degradation of up to 571 degrees C. Fibrous composite membrane PVP/CA/PVP shows a higher value of strain at break (%), and a lower value of tensile strength (MPa) compared to CA/PVP/CA. (C) 2010 Wiley Periodicals, Inc.

As the grain size decreased, the reversible FORC distribution at zero-bias field increased. No grain size dependence of the reversible FORC distributions was observed at high dc electric fields. These results indicate that the grain size dependence CT99021 manufacturer of the small field dielectric constant is attributable to a domain wall contribution. Furthermore, the potential profile through which the domain walls travel changes from a landscape with shallow widely-spaced wells with deep local wells to one with deep widely-spaced wells with shallow local wells, as the grain size decreases.

“Background: Fortification with multiple micronutrients has been shown to improve growth and cognitive performance among children in developing

countries, but it is Cell Cycle inhibitor unknown whether higher concentrations are more effective than lower concentrations.

Objective: We compared the effect of 2 different concentrations of a combination of micronutrients and n-3 (omega-3) fatty acids on indicators of growth and cognitive performance in low-income, marginally nourished schoolchildren in Bangalore, India.

Design: In a 2-by-2 factorial, double-blind, randomized controlled trial, 598 children aged 6-10 y were individually allocated to 1 of 4 intervention groups to receive foods fortified with either 100% or 15% of the Recommended Dietary Allowance of micronutrients in combination with either 900 mg alpha-linolenic acid plus 100 mg docosahexaenoic acid or 140 mg alpha-linolenic acid for 12 mo. Anthropometric and biochemical assessments were performed at baseline and 12 mo. Cognitive performance was measured at baseline and at 6 and 12 mo.

Results: The high micronutrient treatment significantly improved linear growth at 12 mo (0.19 cm; 0.01, 0.36) and short-term memory at 6 mo (0.11

SD; 0.01, 0.20) and was less beneficial on fluid reasoning at 6 (-0.10 SD; -0.17, -0.03) and 12 (-0.12 SD; -0.20, -0.04) mo than was the low micronutrient treatment, whereas no differences were observed on weight, retrieval ability, cognitive speediness, and overall cognitive performance. No significant differences LY2090314 were found between the n-3 treatments.

Conclusions: The high micronutrient treatment was more beneficial for linear growth than was the low micronutrient treatment. However, with some small differential effects, higher micronutrient concentrations were as effective as lower concentrations on cognitive performance.

“Vaccination is a well accepted strategy for control of foot-and-mouth disease (FMD) in endemic countries. Currently, chemically inactivated virus antigens are used for preparation of FMD vaccine. To develop a non-infectious and safe recombinant vaccine, we expressed structural polypeptide of FMDV (O/IND/R2/75) using baculovirus expression system.

Methods: For each study, the relative efficacy of LAIV versus TIV was analyzed by time interval (0-4 and >4-8 months postvaccination) for matched and mismatched strains.

Results: LAIV recipients had less influenza

than TIV recipients during both intervals; the relative efficacy of LAIV versus TIV for matched strains in each study increased from 0 to 4 months (range, 25%-60%) to >4 to 8 months (range, 49%-89%). Analysis of the incidence of individual types/subtypes revealed the same pattern for the predominant matched strain in each study; no consistent pattern was seen for lower-incidence matched strains. For mismatched strains, similar relative efficacy was seen in each time interval.

Conclusions: For matched strains, data suggest that the relative efficacy of LAIV versus TIV in young children increases over time. Consistent with previous studies of TIV-induced Staurosporine purchase immunity, this analysis suggests that the absolute efficacy of TIV against matched strains in children may be lower at >4 to 8 versus 0 to 4 months postvaccination. Relative efficacy against mismatched strains was similar over time, SBE-β-CD in vivo consistent with previous estimates of the absolute efficacies of the vaccines against mismatched strains.

“Introduction and hypothesis This article aims to evaluate how constipation symptoms change after pelvic reconstructive surgery using the Patient Assessment of Constipation Symptom Questionnaire (PAC-SYM). Our primary

hypothesis was that constipation would improve after surgery.

Methods Ninety-four subjects completed the PAC-SYM before and 7 weeks after pelvic reconstructive surgery from 2007 through 2009 inclusive. PAC-SYM scores were compared for the cohort before and 7 weeks post-surgery and based on route of surgery: vaginal selleck chemicals llc or abdominal.

Results Baseline PAC-SYM scores between those undergoing abdominal or vaginal reconstructive surgery were not significantly different (0.76 versus 0.83, respectively; p=0.586). Subjects in the vaginal surgery group had a significant reduction in PAC-SYM scores, 0.83 to 0.62 (p=0.049). After abdominal surgery, subjects had an increase in abdominal subscale scores, 0.69 to 1.03 (p=0.012).

Conclusions Women undergoing vaginal prolapse surgery may have a short-term improvement in constipation symptoms, while those undergoing abdominal surgery have worsening of abdominal constipation symptoms.”

“Many

nonwoven fabrics are made by melt spinning semicrystalline fibers followed by thermal bonding using heated calendar rolls. In this work, we have studied thermal bonding of polypropylene films to simulate bonding of nonwoven fibers. We have tried to relate the thermal bond strengths with the concepts of chain dynamics via interfacial adhesion development at symmetric polymer interfaces. This requires relating the microscopic dynamics of chains with macroscopic interfacial adhesion measurements. It was found that the interfacial bond strength was proportional to the fraction of the crystals melted. This required GSK1838705A heating the interfacial region between the polymer layers into the melting region. Bond strengths were also related to process time as t(1/2). This dependence is consistent with the literature for

reptation, but is also due to the required thermal diffusion to bring the interfacial region to the bonding temperature. Finally, the bond strength is also dependent on the polymer molecular weight as 1/M(1/2), which is consistent with forming the bonds via chain reptation, provided that the bonding time is less than the reptation time.

“Viral infections have been associated with the rejection of transplanted allografts in humans and mice, and the induction of tolerance to allogeneic tissues in mice is abrogated by an ongoing Copanlisib viral infection and inhibited in virus-immune mice. One proposed mechanism for this ‘heterologous immunity’ is the induction of alloreactive T cell responses that cross-react with virus-derived antigens. These cross-reactive CD8 T cells are generated during acute viral infection and survive into memory, but their ability to partake in the immune response to allografts in vivo is not known. We show here that cross-reactive, virus-specific memory CD8 T cells from mice

infected with LCMV proliferated in response to allografts. CD8 T cells specific to several LCMV epitopes proliferated in response to alloantigens, with the magnitude and hierarchy of epitope-specific responses varying with the private specificities of the host memory find more T cell repertoire, as shown by adoptive transfer studies. Last, we show that purified LCMV-specific CD8 T cells rejected skin allografts in SCID mice. These β-Nicotinamide datasheet findings therefore implicate a potential role for heterologous immunity in virus-induced allograft rejection.”
“Magnetocapacitance (MC) measurements-that is, measuring capacitance as a function of temperature at constant magnetic field-has been carried out on a quasi-1D compound, Ca3CoMnO6. MC reveals

the presence of a magnetodielectric effect (MDE), which in turn signals the presence of magnetoelectric coupling below the magnetic ordering temperature, T-N (- 15 K). We also observed the sign reversal of the MDE as the temperature increased from 3 to 20 K. The MDE is positive at 3 K and negative between 3 and 15 K, and it saturates to a near zero value above 15 K. The sign change of the MDE is explained in terms the spin-pair correlation of neighboring spins of Co/Mn at a given applied magnetic field H. A negative MDE signifies antiferromagnetic ordering, and a positive MDE signifies ferromagnetic/paramagnetic ordering. Neutron diffraction study reveals changes in the magnetic structure in the temperature range of 2 to 10 K. The present work brings out the possible correlation between the magnetic structure and the dielectric properties of Ca3CoMnO6. (c) 2011 American Institute of Physics. [doi: 10.1063/1.

Methods. Systematic review of the literature, focused on randomized controlled trials to assess the heterogeneity of treatment effect of psychological factors on the outcomes of fusion versus nonoperative care of the treatment of chronic Fer-1 in vitro low back pain. In the analysis of psychological screening tests, we searched for the most commonly reported questionnaires and those that had been shown to predict lower back pain treatment outcomes.

Results. Few studies comparing fusion to conservative management reported differences in outcome by the presence or absence of a psychological disorder.

Among those that did, we observed the effect of fusion compared with conservative management was more favorable in patients NSC23766 cost without a personality disorder, neuroticism, or depression. The most commonly reported, validated psychological screening tests for lower back pain are the Beck Depression Inventory, the Fear Avoidance Belief Questionnaire, the Spielberger Trait Anxiety Inventory, the Zung Depression Scale, and the Distress Risk Assessment Method.

Conclusion. Psychological disorders affect chronic lower back pain treatment outcomes. Patients

with a personality disorder appear to respond more favorably to conservative management and those without a personality disorder more favorably to fusion. Patients with higher depression and neuroticism scores may also respond more favorably to conservative management.

Clinical Recommendations. Recommendation 1: Chronic

LBP patients with depression, neuroticism, and certain personality disorders should preferentially be treated nonoperatively. Strength of recommendation: Weak.

Recommendation 2: Consider the use of a validated psychological screening questionnaire such as the BDI, FABQ, DRAM, ZDI or STAI, when treating patients with CLBP. Strength of recommendation: Weak.”
“The modified Atkins diet has been studied in mostly short-term clinical trials and case series. No studies have systematically examined the long-term benefits and side effects. Cell Cycle inhibitor The modified Atkins diet was started without prior ketogenic diet use in 87 children at the Johns Hopkins Hospital since 2002, of which 54 continued for more than 6 months. Children who had not been seen within the past 2 years were contacted by phone and email. At their most recent point during the modified Atkins diet (mean 19.9 months), 30 of 54 (55%) children with diet durations of more than 6 months achieved > 50% improvement; 19 (35%) were seizure-free. Using an intent-to-treat analysis, at 12 months, 33 of 87 (38%) had > 50% seizure reduction; 16 (18%) were seizure-free. These results are similar to published data for short-term modified Atkins diet and long-term ketogenic diet use. Side effects were predominantly elevations in lipid profile and gastrointestinal upset.

The transcriptional network through which BES1 and BZR regulate large number of target genes is mostly unknown. By combining chromatin immunoprecipitation coupled with click here Arabidopsis tiling arrays (ChIP-chip) and gene

expression studies, we have identified 1609 putative BES1 target genes, 404 of which are regulated by BRs and/or in gain-of-function bes1-D mutant. BES1 targets contribute to BR responses and interactions with other hormonal or light signaling pathways. Computational modeling of gene expression data using Algorithm for the Reconstruction of Accurate Cellular Networks (ARACNe) reveals that BES1-targeted transcriptional factors form a gene regulatory network (GRN). Mutants of many genes in the network displayed defects in BR responses. Moreover,

we found that BES1 functions to inhibit chloroplast development by repressing the expression of GLK1 and GLK2 transcription factors, Lonafarnib confirming a hypothesis generated from the GRN. Our results thus provide a global view of BR regulated gene expression and a GRN that guides future studies in understanding BR-regulated plant growth.”
“Immune thrombocytopenic purpura (ITP) is one of the most common hemorrhagic disorders in childhood. Platelet microparticles (PMPs) arise with platelet activation with procoagulant activity. Elevated PMP levels in adult ITP were reported to be thrombogenic in certain settings. However, their clinical significance in pediatric ITP was not studied. The aims of this study were to assess PMP levels in ITP in children and adolescents, and its correlation with clinical status and bleeding score. The study included 40 ITP patients (20 acute aged 9 +/- 2.19 years and 20 chronic aged 10.8 +/- 4.7 years)

randomly selected from the Hematology Clinic, Children’s Hospital, Ain Shams University, Cairo, Egypt, and 30 sex- and age-matched healthy controls aged 9 +/- 3.28 years. Patients were subjected to detailed history, assessment of bleeding score, complete hemogram, cytological bone selleck inhibitor marrow examination, and PMP quantification in peripheral blood by flow cytometry. Acute ITP patients had significant increase in PMPs, PMP/platelet count, and PMP percent compared to controls (P = .002, P < .0001, P < .0001, respectively) and compared to chronic ITP patients (P < .0001, P < .0001, P < .0001, respectively). PMPs were significantly decreased in chronic ITP patients compared to controls (P = .001), but PMP/platelet and PMP percent showed highly significant increase in chronic ITP (P < .0001). No correlation was evident between PMP levels and platelet count in either group (P > .05). Neither higher bleeding score nor thrombotic manifestations were observed in the studied ITP patients with high PMP levels. Elevated PMP levels may be protective against severe bleeding events in pediatric ITP. The role of PMP studies in deciding the management plan of childhood and adolescent ITP needs further evaluation.</.

Generally, IgA deficiency appears better tolerated. Replenishment of IgG in patients with hypogammaglobulinemia reduces the infection risk to background if IgG levels are maintained at approximately 500 mg/dL, although higher levels may be necessary in the presence of certain comorbidities. Transient depletion of IgG and/or

IgM (or, less commonly, IgA) can occur in some patients following the administration of certain drugs, including anticonvulsants, corticosteroids, and rituximab. Available evidence suggests that such changes are not generally associated with an increased risk of infections.

Conclusions: While prolonged, very low levels of IgG and/or IgM are associated with a heightened risk of infections, transient or less severe immunodeficiency appears to be tolerated in most subjects. (C) 2008 Elsevier Inc. All rights reserved. Semin Arthritis Rheum 39:18-29″
“Contents Melatonin is thought to be the Selleckchem Cyclopamine main molecule that transmits the signal of seasonal change to the neuroendocrine system in seasonal breeding species. Melatonin exerts its effects through specific melatonin receptors, MTNR1A and MTNR1B. In the present study, six native goat breeds in China and one introduced goat

breed were analysed to investigate the relationship between the genetic polymorphism of receptor genes and seasonal reproduction. Sequencing results showed that there were five polymorphic mutations in the MTNR1A gene and two in the 5-Fluoracil molecular weight MTNR1B gene. In the MTNR1A gene, genotypes AA, AB and BB for 424C>T and genotypes CC, CD and DD for 589C>A were observed in these goat breeds. In all six native goat breeds, only genotype AA was detected. In the MTNR1B gene, genotypes EE, EF and FF for 1179G>A and genotypes GG, GH and HH for 1529A>G were detected. However, in Gulin Ma goats, the genotypes EE and HH were not found. Moreover, the base Z-IETD-FMK of G at position 1179 and A at position 1529 were linked (By Arlequin ver 3.1, Zoological Institute, Berne, Switzerland, http://cmpg.unibe.ch/software/arlequin3,D=0.7496,

r(2)=0.4421, (2)=489.8679, p=0.000). Among these mutations, no amino acid change was found in MTNR1A, while both of the mutations in MTNR1B gene caused amino acid changes of R222H and S339G, respectively. The structural analysis showed that the R222H mutation occurred in the first amino acid residue of the third cytoplasmic loop, and the S339G mutation was located in the carboxyl terminus of the protein. In terms of seasonal breeding, all the genotypes we detected showed a similar kidding frequency distribution trend with a higher frequency in May-August than in January-April and in September-December. This suggests that the relationship between the polymorphisms in the MTNR1A and MTNR1B genes and seasonal breeding could not be established.”

“BACKGROUND: There is renewed interest in the chronic respiratory sequelae of pulmonary tuberculosis (PTB), particularly chronic airflow limitation. A number of South African epidemiological studies have been published, which, although not specifically designed to examine this association, provide useful data on the nature of the relationship.

OBJECTIVE: To review population-based and occupational studies conducted in South Africa that provide estimates of the association between PTB, chronic symptoms and lung function loss.

RESULTS: Two general population and a number of occupational studies were included. Most were able to control for

likely confounders. Chronic chest symptoms and lung function loss were consistently associated with PTB, whether measured by self-report or prospectively in cohort studies. Odds ratios (ORs) were higher for chronic bronchitis (range 1.5-7.2) than for asthma (range Selleck LY2835219 0.7-2.2). For spirometrically defined chronic obstructive pulmonary disease, the OR range was 2.6-8.9, depending on definition. Combined obstructive/restrictive lung function loss was the most common

functional outcome, with a net obstructive effect. The association of past TB with non-specific bronchial hyperresponsiveness was equivocal.

CONCLUSION: These studies add to the evidence of a strong association between PTB, even if treated, and subsequent airflow obstruction as well as restrictive loss. Unanswered questions include extent of recovery KPT-8602 Transmembrane Transporters inhibitor over time, effect modification by smoking and other cofactors, and degree of reversibility by treatment.”
“Objective: To investigate Cell Cycle inhibitor whether an exercise program, initially focusing on knee stabilization and subsequently on muscle strength and performance of daily activities is more effective than an exercise program focusing on muscle strength and performance of daily activities only, in reducing activity limitations in patients with knee osteoarthritis (OA) and instability of the

knee joint.

Design: A single-blind, randomized, controlled trial involving 159 knee OA patients with self-reported and/or biomechanically assessed knee instability, randomly assigned to two treatment groups. Both groups received a supervised exercise program for 12 weeks, consisting of muscle strengthening exercises and training of daily activities, but only in the experimental group specific knee joint stabilization training was provided. Outcome measures included activity limitations (Western Ontario and McMaster Universities Osteoarthritis Index – WOMAC physical function, primary outcome), pain, global perceived effect and knee stability.

Results: Both treatment groups demonstrated large (similar to 20-40%) and clinically relevant reductions in activity limitations, pain and knee instability, which were sustained 6 months post-treatment.
