    Increased levels of peripheral inflammatory markers, including C-Reactive Protein (CRP), are associated with increased risk for depression, anxiety, and suicidality. The brain mechanisms that may underlie the association between peripheral inflammation and internalizing problems remain to be determined. The present study examines associations between peripheral CRP concentrations and threat-related amygdala activity, a neural biomarker of depression and anxiety risk, in a sample of 172 young adult undergraduate students. Participants underwent functional MRI scanning while performing an emotional face matching task to obtain a measure of threat-related amygdala activity to angry and fearful faces; CRP concentrations were assayed from dried blood spots. Results indicated a significant interaction between CRP and sex: in men, but not women, higher CRP was associated with higher threat-related amygdala activity. These results add to the literature finding associations between systemic levels of inflammation and brain function and suggest that threat-related amygdala activity may serve as a potential pathway through which heightened chronic inflammation may increase risk for mood and anxiety problems.

    Introduction: Several mechanisms have been proposed to explain the adverse effect of obesity on quality of life among women with breast cancer, including alteration in some inflammatory markers. The aim of this study was to determine the status of serum levels of leptin, IL-6 and CRP in obese, overweight and normal weight breast cancer survivors in order to determine the relationship between inflammatory markers’ levels and obesity. Materials and methods: This cross-sectional study was done on 75 women with breast cancer, 30 obese, 15 overweight and 30 normal weight patients. Serum leptin, IL-6, CRP, total protein, albumin and lipid profile as well as anthropometric parameters were measured in three groups. Results: Serum leptin levels of obese patients were significantly higher than those of overweight and normal weight patients ( P < 0.05). Higher serum CRP and lower albumin levels were observed in obese patients in comparison with normal weight patients ( P < 0.05). HDL-C level was significantly different between overweight and normal weight patients ( P < 0.05). Significant differences in serum IL-6 levels were not observed between the study groups ( P > 0.05). Moreover, multiple regression analysis showed that leptin was significantly associated with BMI ( P < 0.001), while albumin was negatively correlated with BMI ( P < 0.05). CRP levels were significantly correlated with BMI and waist-to-hip ratio (WHR) ( P < 0.05). Conclusions: In conclusion, high leptin levels and alteration in acute phase proteins in obese patients may exaggerate the inflammation status. As inflammation has the potential to increase the susceptibility of the patients to metastasis development, it is necessary to decline its rate.

    To undertake a systematic review and meta-analysis of randomized controlled trials of the effect of glucagon-like peptide-1 receptor agonist (GLP-1 RAs) therapy on serum C-reactive protein (CRP) concentrations. PubMed-Medline, SCOPUS, Web of Science and Google Scholar databases were searched for the period up until March 16, 2016. Prospective studies evaluating the impact of GLP-1 RAs on serum CRP were identified. A random effects model (using the DerSimonian-Laird method) and generic inverse variance methods were used for quantitative data synthesis. Sensitivity analysis was conducted using the leave-one-out method. Heterogeneity was quantitatively assessed using the I 2 index. Random effects meta-regression was performed using unrestricted maximum likelihood method to evaluate the impact of potential moderator. International Prospective Register for Systematic Reviews (PROSPERO) number CRD42016036868. Meta-analysis of the data from 7 treatment arms revealed a significant reduction in serum CRP concentrations following treatment with GLP-1 RAs (WMD -2.14 (mg/dL), 95% CI -3.51, -0.78, P=0.002; I 2 96.1%). Removal of one study in the meta-analysis did not change the result in the sensitivity analysis (WMD -2.14 (mg/dL), 95% CI -3.51, -0.78, P=0.002; I 2 96.1%), indicating that our results could not be solely attributed to the effect of a single study. Random effects meta-regression was performed to evaluate the impact of potential moderator on the estimated effect size. Changes in serum CRP concentration were associated with the duration of treatment (slope -0.097, 95% CI -0.158, -0.042, Pmeta-analysis suggests that GLP-1 RAs therapy causes a significant reduction in CRP.

    A wide range of recent studies have detected inflammation as one of the most influent factors in the appearance and spreading of neurodegenerative brain diseases. We aimed to understand the influence of Interleukin-6 (IL-6), C-reactive protein (CRP) and homocysteine (Hcy) on patients suffering from Alzheimer׳s disease (AD) and on their descendants. Three groups of subjects were analyzed: 55 patients suffering from AD, 51 middle-aged daughters of the patients of the first group, and 53 subjects without positive family history of AD. The results of the conducted research are in accordance with the present scientific knowledge, namely a statistically significant difference for examined parameters has been determined between women suffering from AD and their daughters and control group examinees. No difference was found in serum concentrations of IL-6, highly sensitive C-reactive protein (hsCRP) and Hcy between the groups of the middle-aged descendants of patients with AD and healthy controls without family history of AD. This finding supports the hypothesis that these markers may not play causal role in the development of AD. This is supported by the obtained positive correlation between IL-6 and hsCRP and IL-6 and Hcy in AD patients while there is no such correlation between female subjects with or without a family history of AD.

    Elevations in C-reactive protein (CRP) concentration are associated with an increased risk of future coronary events in prospective studies and it has been suggested that CRP could be used to aid risk prediction. A +1444C>T polymorphism in the CRP gene has been associated with differences in CRP concentration. We investigated the effect of this polymorphism on the CRP response to periodontal therapy, an intermediate inflammatory stimulus. Clinical parameters, CRP, and interleukin-6 (IL-6) concentrations were evaluated in 55 consecutive patients suffering from periodontitis at baseline, 1, 7 and 30 days after an intensive course of periodontal treatment. In a multivariate analysis individuals homozygous for the +1444T allele showed higher CRP concentrations (day 1, 21.10+/-4.81 mg/L and day 7, 4.89+/-0.74 mg/L) compared with C-allele carriers (day 1, 12.37+/-1.61 mg/L and day 7, 3.08+/-2.00 mg/L). This effect was independent of conventional cardiovascular risk factors and inflammatory factors known to affect CRP concentrations. CRP genotype may need to be considered when CRP values are used in coronary risk prediction.

    concentration in the salt solution reduced the time to peak heat flow, and reducing the amount of slag in the premix increased the time to peak heat flow. These observations may help to describe some of the cured properties of the samples, in particular the differences in compressive strength observed after 28 and 90 days of curing. Samples were cured for at least 28 days at ambient temperature in the laboratory prior to cured properties analyses. The low activity waste form for disposal at the Hanford Site is required to have a compressive strength of at least 500 psi. After 28 days of curing, several of the test mixes had mean compressive strengths that were below the 500 psi requirement. Higher sodium concentrations and higher water to premix ratios led to reduced compressive strength. Higher fly ash concentrations decreased the compressive strength after 28 days of curing. This may be explained in that the cementitious phases matured more quickly in the mixes with higher concentrations of slag, as evidenced by the data for the time to peak heat generation. All of the test mixes exhibited higher mean compressive strengths after 90 days of curing, with only one composition having a mean compressive strength of less than 500 psi. Leach indices were determined for the test mixes for contaminants of interest. The leaching performance of the mixes evaluated in this study was not particularly sensitive to the factors used in the experimental design. This may be beneficial in demonstrating that the performance of the waste form is robust with respect to changes in the mix composition. The results of this study demonstrate the potential to achieve significantly higher waste loadings in Cast Stone and other low temperature, cementitious waste forms. Additional work is needed to elucidate the hydration mechanisms occurring in Cast Stone formulated with highly concentrated salt solutions since these reactions are responsible for determining the performance of the cured waste form.

    The concentrations of ten trace elements, As, Br, Cd, Cu, Hg, I, Mn, Se, Zn and V, have been determined in up to 27 species of higher fungi from several sites in Slovenia, Yugoslavia. Analyses were based on destructive neutron activation techniques. Data are presented and compared with the concentrations found in soils. Previously values were non-existent or scanty for these elements, so that the data represent typical levels for basidiomycetes. In addition to confirming high levels of mercury in many species, the survey also found that cadmium is accumulated to a surprising extent by most fungi, the average value being 5 ppm. Among other accumulations found was bromine by the genus Amanita, and selenium by edible Boletus. Correlation analysis between all pairs of trace elements gave values for r of from 0.75 to 0.43 for 7 pairs (Cu and Hg, 0.75; Se and As, 0.69). As well as these features of biochemical interest, the values found and the pattern of accumulation suggest potential uses of fungi in environmental studies

    Full Text Available Abstract    BACKGROUND: Atherosclerosis is the most important underlying cause of cardiovascular diseases (CVD which recently has been classified as an inflammatory disorder. Accumulation of large amounts of oxidized LDL in the intima during local inflammation reaction led to increase several factors such as C -reactive protein (CRP. It has also been reported that CRP is able to bind with modified forms of LDL as well as oxidized LDL. These findings suggest possible positive or negative involvement of this protein in atherogenesis. The main objective of the present study was to assess the influence of CRP on LDL oxidation and the possible physical \\changes of LDL in the presence of CRP in vitro.    METHODS: In this study, the susceptibility of purified LDL to oxidation was assayed by monitoring of formation of conjugated dienes in different physiological concentrations of CRP (0 - 0.5 -2  µg/ml using a shimadzu spectrophotometer. Electrophoresis was used to determine the electrophoretic mobility of LDL in those conditions.    RESULTS: CRP significantly reduced the susceptibility of Cu++ -induced LDL oxidation through increasing the lag timeand there was positive relationship between these findings and CRP concentration (P < 0.05. CRP caused a significant reduction in the electrophotretic mobility of LDL compared to native LDL (n-LDL (P<0.05.     CONCLUSION: A considerable reduction was shown in LDL oxidation, in higher concentration of CRP, via an unknown mechanism. The electrophoretic mobility of LDL, in the oxidative condition, decreases in the presence of CRP compared to n-LDL, which can be indicative of the effect of this protein on the physical and chemical properties of LDL. It seems that, other pathway than LDL oxidation is responsible for the effect of CRP on the atherogenesis processes.      Keywords: Atherosclerosis, Creactive protein, Low-density lipoprotein, Inflammation.

    Full Text Available It has been proved that hyperhomocysteinemia has a high prevalence in patients with end-stage renal disease (ESRD, which may contribute to the high cardiovascular risk in these patients. Cardiovascular disease is the first cause of high mortality rate in ESRD patients. The aim of the present study was to assess five important factors in patients with ESRD (the amount of homocysteine, IL-6, TNF-alpha, hs-CRP, and Total Antioxidant Capacity. These factors were surveyed in ESRD patients to compare with healthy subjects. In a cross-sectional study, we enrolled 80 patients on maintenance hemodialysis and measured the inflammatory and oxidative stress indicators. The plasma samples were assayed for five above mentioned variables using standard protocols. Two-hour post hemodialysis plasma samples were also assayed for TAC. Plasma levels of inflammation markers, IL-6 and hs-CRP, homocysteine were significantly increased in ESRD group versus control group. This increase was also found in TNF-α levels as compared to the controls, but the differences were not statistically significant. Also, the post dialysis samples had significantly lower levels of TAC as compared to predialysis ones.

    Full Text Available Background: Inflammation has been proposed as a contributor to different stages in the pathogenesis of Coronary Heart Disease (CHD. High sensitive C-Reactive Protein (hs-CRP, an acute-phase plasma protein synthesized by the liver, is the most extensively studied systemic marker of inflammation. Elevated hsCRP concentrations early in Acute Coronary Syndrome (ACS, prior to the tissue necrosis, may be a surrogate marker for cardiovascular co-morbidities. The cardiac marker enzymes Creatine Kinase myocardial bound (CK-MB, Aspartate Aminotransferase (AST and lactate dehydrogenase (LDH have been known to be increased in coronary artery diseases. Objective: The aim of the study was to measure hs-CRP levels and other cardiac marker enzymes in ACS patients and to compare the levels of hs-CRP with other cardiac marker enzymes between ST Elevation Myocardial Infarction (STEMI and Non-ST Elevation Myocardial Infarction (NSTEMI patients. Material and Methods: The study group consisted of 207 consecutive patients admitted to Sri Siddhartha Medical College Hospital within the first 6 hours from the onset of chest pain. Patients were diagnosed as Unstable Angina (UA, (n=84; STEMI (n=63 and NSTEMI (n=60. ACS patients were compared with 211 healthy age and sex matched controls. Hs-CRP, CK-MB, AST and LDH levels were measured by standard methods in both groups at baseline and forcases at 36-48 hours i.e. Peak levels. Results: ACS patients had significantly (p<0.05 higher levels of hs-CRP, CKMB, AST and LDH in comparison to controls at baseline. Hs-CRP, CK-MB, AST and LDH levels were significantly higher in STEMI patients compared to NSTEMI patients (p<0.05 at baseline. There was a significant difference regarding peak hs-CRP levels between the two groups, as STEMI patients had significantly higher peak hs-CRP levels compared to NSTEMI patients (p<0.05. Conclusion: STEMI patients have significantly higher peak hsCRP levels compared to NSTEMI patients. These data

    C-reactive protein (CRP) is considered a marker of subclinical atherosclerosis. The aim of the study was to assess whether the metabolic syndrome (MS) and parameters involved in its diagnosis might influence serum CRP values. Cross-sectional study in outpatients of a HTA and Vascular Risk clinic. MS was diagnosed according to National Cholesterol Educational Program ATP-III guidelines, and hs-CRP was analyzed by nephelometry. A total of 1,969 patients (47% male) were evaluated and distributed into four groups: 1) 1,220 non-diabetics without MS; 2) 384 non-diabetics with MS; 3) 153 diabetics without MS, and 4) 212 diabetics with MS. Patients with MS had higher CRP in both non-diabetic 3.0 (1.7-4.4) mg/l vs. 1.7 (0.9-3.4) mg/l; p=0.001 (MW), and diabetic patients: 2.8 (1.5-4.6) mg/l vs. 2.2 (0.9-4.3) mg/l; p=0.01 (MW). Diabetic patients without MS had CRP values not different to non-diabetic without MS. CRP values increased in relation to the number of parameters included in the MS from 1.7 (2.2) mg/l, in patients without any parameters, to 4.2 (2.8) mg/l in patients who fulfilled five parameters (p=0.001) (KW). In multiple regression analysis abdominal obesity (p=0.001), TG (p=0.001) and glucose (p=0.02) were associated with CRP levels after correcting for other factors. Abdominal obesity (OR: 1.9; 95% CI: 1.5-2.4; p=0.001) and TG (OR: 1.4; 95% CI: 1.1 -1.7; p=0.003), but not glucose were independent factors related to the presence of high levels of CRP (>3 mg/l) in a logistic regression analysis. Diabetic and non-diabetic patients with MS have high CRP levels. Of the five components of MS, the most closely related to CRP is abdominal obesity.

    Increased lipoprotein (a) [Lp(a)] concentration was reported to be an independent risk factor for coronary heart disease (CHD). Recent epidemiological studies affirmed the value of C-reactive protein (CRP) as the strongest, univariate predictor of the cardiovascular events. We decided to establish cut-off levels providing maximum diagnostic efficiency for CHD. In this study we measured CRP and Lp(a) concentrations in patients with angiographically demonstrated CHD (group A, n: 120), patients without any angiographically demonstrable lesion (group B, n: 62) and a group of healthy subjects (group C, n: 41). Data were evaluated correcting for lipid and lipoprotein concentrations, diabetes mellitus, hypertension, smoking, age, and body mass index in men and women. ROC curve based cut-off values (comparing group A versus groups B and C) and associated diagnostic performances of the assays were evaluated. Significant increases were noted in serum CRP concentrations in men and women, in groups A vs. B,A vs. C, B vs. C. Lp(a) concentrations were not different among groups in men but were higher in group A vs. B and C in women. Optimal cut-off levels for CRP in women and men were found as 2.1 and 3.0 mg/l with the diagnostic values of 0.792 and 0.770, respectively. For Lp(a) optimal cut-off levels were found as 22.6 and 9.8 mg/dl with the diagnostic values of 0.612 and 0.596 in women and men, respectively. The CRP level is quite efficient for separation of patients from controls. Therefore keeping in mind the lack of specificity, the CRP level may be a useful tool in the diagnosis of coronary heart disease. However, the Lp(a) level is not efficient enough to support the use of Lp(a) measurement for management of coronary heart disease.

    Background: Adherence to a Mediterranean diet seems to be inversely associated with C-reactive protein (CRP) concentration. A 14-point Mediterranean Diet Adherence Screener (MEDAS) has been developed to assess dietary compliance. Objective: The aim of this study was to assess whether each of the MEDAS questions as well as their final score were associated with the levels of CRP in general Spanish population. Cross-sectional analysis of 1411 subjects (mean age 61 years, 43.0% males) randomly selected from the general population. CRP levels were determined by a commercial ELISA kit. Adherence to the Mediterranean diet was measured by the 14-point MEDAS. Results: There was an inverse correlation between adherence to the Mediterranean diet and the CRP concentration, even after adjusting by age, gender, hypertension, metabolic syndrome, body mass index, statin treatment and hypertension treatment ( p = 0.041). Subjects who consume ≥2 servings of vegetables per day ( p = 0.003), ≥3 pieces of fruit per day ( p = 0.003), ≥1 serving of butter, margarine, or cream per day ( p = 0.041) or ≥3 servings of fish/seafood per week ( p = 0.058) had significantly lower levels of CRP. Conclusions : Adherence to a Mediterranean-type diet measured by a simple questionnaire is associated with lower CRP concentration. However, this association seems to be particularly related to a higher consumption of vegetables, fruits, dairy products, and fish.

    Objective: To study the clinical diagnostic value of determination of plasma ET, Hcy and serum hs-CRP contents in patients with coronary heart disease (CHD). Methods: Plasma ET, Hcy(with RIA) and serum hs-CRP (with immune turbidimetry) contents were determined in 38 patients with CHD and 35 controls. Results: Plasma ET, Hcy and serum hs-CRP concentration were significantly higher in CHD patients (than those in controls P<0.01). Plasma ET levels were significantly positively correlated with those of plasma Hcy and serum hs-CRP (r=0.6122, 0.5842, P<0.01). Conclusion: Detection of changes of plasma ET, Hcy and serum hs-CRP levels might be of prognostic importance in patients with CHD. (authors)

    Full Text Available Elevation in C-reactive protein (CRP levels have been shown in patients with aortic valve stenosis (AS. Minor allele of the CRP gene (CRP rs1205 C>T polymorphism has been associated with lower plasma CRP concentrations in cohorts of healthy and atherosclerotic patients. Considering the existing similarities between atherosclerosis and AS, we examined the effect of CRP rs1205 C>T polymorphism on the AS severity. Three hundred consecutive Caucasian patients diagnosed with AS were genotyped for the rs1205 C>T polymorphism using the TaqMan assay. Severity of the AS was assessed using transthoracic echocardiography. The degree of calcification was analyzed semi-quantitatively. Carriers of the rs1205 T allele were characterized by elevated serum CRP levels (2.53 (1.51–3.96 vs. 1.68 (0.98–2.90 mg/L, p < 0.001 and a higher proportion of the severe aortic valve calcification (70.4% vs. 55.1%, p = 0.01 compared with major homozygotes. The effect of CRP rs1205 polymorphism on CRP levels is opposite in AS-affected than in unaffected subjects, suggesting existence of a disease-specific molecular regulatory mechanism. Furthermore, rs1205 variant allele predisposes to larger aortic valve calcification, potentially being a novel genetic risk marker of disease progression.

    A possibility of using a range of dc and ac electrochemical techniques to probe associative interactions of C-reactive protein (CRP) with CRP antibody (aCRP) immobilized on a gold electrode surface was investigated. It was demonstrated that the investigated electrochemical techniques can be used efficiently to probe these interactions over a wide CRP concentration range, from 1.15 x 10 -5 to 1.15 mg L -1 . The measured sensitivity of the techniques is in the following decreasing order: differential pulse voltammetry, charge-transfer resistance obtained from electrochemical impedance spectroscopy (EIS), cyclic voltammetry, chronoamperometry, and double-layer capacitance deduced from EIS measurements which gave the poorest sensitivity. Measurements of kinetic parameters demonstrated that the associative interactions of CRP with the immobilized aCRP reached quasi-equilibrium after 20-30 min. The kinetics of these interactions was modeled successfully using a two-step kinetic model. In this model, the first step represents reversible CRP-aCRP associative-dissociative interactions, while the second step represents the irreversible transformation of the bound CRP into a thermodynamically stable configuration. It was demonstrated that the thermodynamically stable configuration of CRP starts prevailing after 7 min of interaction of CRP with the immobilized aCRP.

    One of the crp* mutants previously isolated to activate lac promoter in vivo has been characterized with regard to its biochemical properties. CRP*592 shows a more open conformation than CRP as indicated by its sensitivity to proteolytic attack. Dithionitrobenzoic acid mediated intersubunit crosslinking of CRP requires cAMP; this reaction occurs with unliganded CRP*592. Binding of CRP to its site on the lac promoter and activation of abortive initiation is effected by cAMP but not by cGMP. CRP*592 can activate abortive initiation in the presence of cAMP or cGMP and also at a high CRP*592 concentration in the absence of cyclic nucleotide. DNase I footprinting shows that cAMP-CRP* binds to its site on lac P + while unliganded CRP* and cGMP-CRP* form a stable complex with the [ 32 P]lac P + only in the presence of RNA polymerase. While cGMP binds to CRP it cannot replace cAMP in effecting the conformation necessary for site specific promoter binding; the weakly active unliganded CRP*592 can be shifted to a functional conformation by cAMP, cGMP and RNA polymerase

    C-reactive protein (CRP) interacts with phosphorylcholine (PC), Fcγ receptors, complement factor C1q and cell nuclear constituents, yet its biological roles are insufficiently understood. The aim was to characterize CRP-induced complement activation by ellipsometry. PC conjugated with keyhole limpet hemocyanin (PC-KLH) was immobilized to cross-linked fibrinogen. A low-CRP serum with different amounts of added CRP was exposed to the PC-surfaces. The total serum protein deposition was quantified and deposition of IgG, C1q, C3c, C4, factor H, and CRP detected with polyclonal antibodies. The binding of serum CRP to PC-KLH dose-dependently triggered activation of the classical pathway. Unexpectedly, the activation was efficiently down-regulated at CRP levels >150 mg/L. Using radial immunodiffusion, CRP-C1q interaction was observed in serum samples with high CRP concentrations. We propose that the underlying mechanism depends on fluid-phase interaction between C1q and CRP. This might constitute another level of complement regulation, which has implications for systemic lupus erythematosus where CRP is often low despite flare-ups

    C-reactive protein (CRP) is a sensitive marker for inflammation in people and dogs. In people, an association between CRP concentration and atherosclerosis has been reported. Atherosclerosis is rare in dogs, but the Miniature Schnauzer breed may be at increased risk for developing this vascular disease. It is not known if CRP concentrations in Miniature Schnauzer dogs differ from those in other dog breeds. Our objectives were to validate an automated human CRP assay for measuring CRP in dogs and compare CRP concentrations in healthy Miniature Schnauzer dogs with those in non-Miniature Schnauzer breeds. Sera from 37 non-Miniature Schnauzer dogs with inflammatory disease were pooled and used to validate a human CRP immunoturbidimetric assay for measuring canine CRP. Blood was collected from 20 healthy Miniature Schnauzer dogs and 41 healthy dogs of other breeds. Median serum CRP concentration of healthy Miniature Schnauzer dogs was compared with that of healthy non-Miniature Schnauzer dogs. The human CRP assay measured CRP reliably with linearity between 0 and 20 mg/L. CRP concentration for healthy Miniature Schnauzer dogs (median 4.0 mg/L, minimum-maximum 0-18.2 mg/L) was significantly higher than for the healthy non-Miniature Schnauzer dogs (median 0.1 mg/L, minimum-maximum 0-10.7 mg/L); 17 of the 20 Miniature Schnauzer dogs had values that overlapped with those of the non-Miniature Schnauzer dogs. Median CRP concentration of Miniature Schnauzer dogs was slightly higher than that of other breeds of dogs. A relationship between higher CRP concentration in Miniature Schnauzer dogs and idiopathic hyperlipidemia, pancreatitis, and possible increased risk for atherosclerosis remains to be determined. ©2011 American Society for Veterinary Clinical Pathology.

    Current guidelines for cow's milk consumption in children older than age 2 years suggest 1% or 2% milk to reduce the risk of obesity. Given that milk is the main dietary source of vitamin D for North American children and that vitamin D is fat soluble, we hypothesized 25-hydroxyvitamin D (25(OH)D) concentration to be positively associated with the fat content of milk. The objective was to determine the relationship between the fat content of milk consumed and the serum 25(OH)D concentration; our secondary objective was to explore the role that the volume of milk consumed played in this relationship. We completed a cross-sectional study of children aged 12-72 months in the TARGetKids! research network. Multivariable linear regression was used to test the association between milk fat content and child 25(OH)D, adjusted for clinically relevant covariates. The interaction between volume of milk and fat content was examined. Two thousand eight hundred fifty-seven children were included in the analysis. The fat content of milk was positively associated with 25(OH)D (p = 0.03), and the interaction between the volume of milk consumed and the milk fat content was statistically significant (p = 0.005). Children who drank 1% milk needed 2.46 cups (95% confidence interval (CI) 2.38-2.54) of milk to have a 25(OH)D concentration similar to that of children who drank 1 cup of homogenized milk (3.25% fat). Children who consumed 1% milk had 2.05 (95% CI 1.73-2.42) times higher odds of having a 25(OH)D concentration <50 nmol/L compared with children who consumed homogenized milk. In conclusion, recommendations for children to drink lower-fat milk (1% or 2%) may compromise serum 25(OH)D levels and may require study to ensure optimal childhood health.

    Gastric cancer (GC) is a second most common cause of cancer-related death and represents an inflammation-driven malignancy. It has been suggested that interleukin 6 (IL-6) and C-reactive protein (CRP) play a potential role in the growth and progression of GC. The aim of the present study was to compare clinical significance of IL-6 and CRP with classic tumor markers-carcinoembryonic antigen (CEA) and carbohydrate antigen (CA 19-9) in GC patients. The study included 92 patients with GC and 70 healthy subjects. The serum concentrations of IL-6, CEA and CA 19-9 were determined using immunoenzyme assays, whereas CRP using immunoturbidimetric method. We defined the diagnostic criteria and prognostic value for proteins tested. In GC patients, the serum concentrations of all the proteins tested were significantly higher than in healthy subjects. The IL-6, CEA and CA 19-9 levels correlated with nodal metastases, while CRP with tumor stage, gastric wall invasion, presence of nodal and distant metastases. Diagnostic sensitivity of IL-6 was higher (85%) than those of other markers (CRP 66%, CA 19-9 34%, CEA 22%) and increased in combined use with CRP or CEA (88%). The area under ROC curve for IL-6 was larger than those of CRP and classic tumor markers (CEA and CA 19-9). None of the proteins tested was independent prognostic factor for the survival of GC patients. Our findings indicate better usefulness of serum proinflammatory proteins-IL-6 and CRP than classic tumor markers-CEA and CA 19-9 in the diagnosis of GC.

    High sensitivity serum C-reactive protein (hs-CRP) has come into clinical use as a marker of risk for cardiovascular disease (CVD). In addition to a role as a marker of disease, CRP has also been implicated in the pathogenesis of CVD. Specific small-molecule inhibitors of CRP have recently been developed with the intent of mitigating cardiac damage during acute myocardial infarction. However, the use of CRP, both as a risk marker and a disease target are controversial for several reasons. Serum hs-CRP concentrations can be elevated on the basis of genetics, female gender, and non-Caucasian ethnicity. It is not clear, in these contexts, that elevations of hs-CRP have any pathological significance. As a non-specific indicator of inflammation, CRP is also not a specific indicator of a single disease state such as cardiovascular disease but elevated concentrations can be seen in association with other comorbidities including obesity and pulmonary disease. In sharp contrast to the proposed inhibition of CRP for cardiovascular disease treatment, the infusion of CRP has been shown to have profound therapeutic benefits for autoimmune disease and septic shock. The balance between the risks and benefits of these competing views of the role of CRP in disease and disease therapy is reminiscent of the ongoing controversy regarding the use of non-steroidal anti-inflammatory drugs (NSAIDs) for musculoskeletal disease and their cardiovascular side effects. Soon, NSAIDs may not be the only agents about which Rheumatologists and Cardiologists may spar.

    Atomic force microscope (AFM) was exploited to take picture of the molecular topology of C-reactive protein (CRP) in phosphate-buffered saline (PBS) solution. An explicit molecular image of CRP demonstrated a pentagonal structure composed of five subunits. Dimensions of the doughnut-shaped CRP molecule measured by AFM were about 25 nm in outside diameter and 10 nm in central pore diameter, and the height of CRP molecule was about 4 nm which was comparable to the value determined by X-ray crystallography. Bis(N-succinimido)-11,11'-dithiobis (undecyl succinate) (DSNHS) was synthesized for use as a linker for immobilizing anti-CRP antibody (anti-CRP) onto the gold surface of a surface plasmon resonance (SPR) sensor chip. DSNHS formed self-assembled monolayer (SAM) on the gold surface. By use of an AFM tip, a pattern of ditch was engraved within the SAM of DSNHS, and anti-CRP was immobilized on the engraved SAM through replacement of N-hydroxysuccinimide group on the outside surface of DSNHS by the amine group of anti-CRP. Formation of CRP/anti-CRP complex on the gold surface of SPR sensor chip was clearly demonstrated by measuring SPR angle shift. A consecutive series of SAM, SAM/anti-CRP, and SAM/anti-CRP/CRP complexes was generated on a SPR sensor chip, and the changes in depth of the ditch were monitored by taking AFM images of the complexes. Comparative analysis of the depth differences indicates that binding of CRP to anti-CRP occurs in a planar mode

    Full Text Available The influence of diet on inflammation in children remains unclear. We aimed to analyze the influence of diet on high-sensitivity C-reactive protein (hs-CRP levels in a pre-pubertal population free of other influences that may affect hs-CRP levels. We determined hs-CRP levels in 571 six- to eight-year-old children using an hs-CRP ELISA kit. Information on food and nutrient intake was obtained through a food-frequency questionnaire. Overall dietary quality was assessed using the Healthy Eating Index (HEI. We found that girls in the highest tertile of hs-CRP levels had a higher intake of saturated fatty acid, and lower intakes of fiber and vitamin E and a lower HEI score when compared to those in tertiles 1 and 2. We also observed a significant decrease in fruit and vegetable intakes by hs-CRP tertile. Factor analysis showed that a dietary pattern that was loaded most strongly with vegetable, fruit, fiber and vitamin A and E intakes correlated negatively (−0.132, p < 0.05 with hs-CRP. No such association was found in boys. In conclusion, our data show that girls with a poorer quality diet show higher hs-CRP levels already at a pre-pubertal age.

    HsCRP protein is known as a novel marker of low grade inflammatory state, which characterises an atherosclerotic process in its early stages. Contrary to a large amount of data on inflammatory markers in diabetes type 2 and metabolic syndrome in adults, little is known so far about the inflammatory process in diabetes type 1, especially in children. The aim of the study was to estimate the level of hsCRP protein in children and adolescents with diabetes type 1 depending on coexisting additional risk factors for atherosclerosis and microvascular complications. 127 children and adolescents with diabetes duration 6.7+/-3.3 years, aged 14.9+/-3.1, were studied. The control group consisted of 52 healthy children aged 14.9+/-2.8 years, matched acc. to gender. HsCRP level was assessed with use of immunoturbidymetric, latex augmented method (Tina-quant CRP (Latex) HS, Roche). HsCRP in the whole study group was nearly significantly higher compared to control group: 0.17+/-0.2 vs. 0.078+/-0.1 mg/dl, p=0.072. In diabetic hypertensive children (n=38) we found significantly higher levels of hsCRP compared to controls (0.27+/-0.3 vs. 0.07 mg/dl, p=0.008) and compared to diabetic normotensive children (0.13+/-0.22 mg/dl; p=0.024). Diabetic obese patients (n=23) had significantly higer hsCRP compared to controls (0.24+/-0.3 vs. 0.07+/-0.1 mg/dl, p=0.04). In 14 studied diabetic children we found coexisting hypertension and obesity, and we found further increase in hsCRP level - 0.28+/-0.3 mg/dl. In diabetic children with microangiopathy hsCRP level was 0.22+/-0.2 mg/dl, and it was insignificantly higher compared to controls and to diabetic children without complications. Correlation analysis showed interrelations between hsCRP and systolic blood pressure (r=0.2; p=0.04) and HbA1c (r=0.25; p=0.015). In stepwise regression analysis hsCRP was related to systolic blood pressure, HbA1c and the triglycerides level (R=0.37; p=0.003). In children and adolescents with diabetes type 1 we

    Comparison of polychlorinated biphenyl (PCB) concentrations between the sexes of mature fish may reveal important behavioral and physiological differences between the sexes. We determined whole-fish PCB concentrations in 23 female summer flounder Paralichthys dentatus and 27 male summer flounder from New Jersey coastal waters. To investigate the potential for differences in diet or habitat utilization between the sexes, carbon and nitrogen stable isotope ratios were also determined. In 5 of the 23 female summer flounder, PCB concentrations in the somatic tissue and ovaries were determined. In addition, we used bioenergetics modeling to assess the contribution of the growth dilution effect to the observed difference in PCB concentrations between the sexes. Whole-fish PCB concentrations for females and males averaged 87 and 124 ng/g, respectively; thus males were 43% higher in PCB concentration compared with females. Carbon and nitrogen stable isotope ratios did not significantly differ between the sexes, suggesting that diet composition and habitat utilization did not vary between the sexes. Based on PCB determinations in the somatic tissue and ovaries, we predicted that PCB concentration of females would increase by 0.6%, on average, immediately after spawning due to release of eggs. Thus, the change in PCB concentration due to release of eggs did not explain the higher PCB concentrations observed in males. Bioenergetics modeling results indicated that the growth dilution effect could account for males being 19% higher in PCB concentration compared with females. Thus, the bulk of the observed difference in PCB concentrations between the sexes was not explained by growth dilution. We concluded that a higher rate of energy expenditure in males, stemming from greater activity and a greater resting metabolic rate, was most likely the primary driver for the observed difference in PCB concentrations between the sexes.

    To explore the mechanism of coronary heart disease and the effect of therapy on unstable angina pectoris (UAP) OLAB, brain natriuretic peptide (BNP) and supersensitive C reaction protein(CRP) levels in the plasma of patients with coronary heart disease were detected. The OLAB, BNP and CRP levels and their correlations in the plasma of 124 patients with coronary heart disease and 30 controls were determined by chemiluminescence and ELISA technique, respectively. The OLAB, BNP and CRP levels of 48 UAP patients after PTCA were also analyzed. The BNP and CRP levels of patients with coronary heart disease, especially acute myocardial infarction (AMI) and UAP patients to stable angina pectoris (SAP) patients were higher than those of controls (P<0.01). The OLAB levels in AMI patients was higher than UAP, SAP and controls (P<0.05). There was a significant difference of OLAB, BNP and CRP levels in UAP patients before and after PTCA therapy (P<0.05). OLAB, BNP and CRP, which is involved in the developing procedure of coronary heart disease, may be used to predict the long-term cardiac function recover. OLAB, BNP and CRP levels in UAP patients were decreased significantly after PTCA and may also be considered as the therapy effect observing markers. OLAB takes part in the whole procedure of coronary atherosclerosis and the occurrence and ending of AMI. (authors)

    Strokes are caused by disruption of the blood supply to the brain. This may result from either blockage or rupture of a blood vessel. Yearly 15 million people worldwide suffer a stroke. India ranks second worldwide in terms of deaths from stroke. The incidence of stroke increases with age affecting the economically productive middle aged population. Hypertension and male sex are other risk factors for stroke. C-Reactive Protein (CRP) is an acute phase protein whose concentration rises in blood following inflammation. Formerly, assays for CRP detected its rise only after significant inflammation. However, recently developed high sensitivity assays (hsCRP) enable the measurement of CRP in individuals who are apparently healthy. Several studies indicate that hsCRP is elevated in individuals who are at risk of developing Coronary Artery Disease or Cerebrovascular events, the elevation may be found years before the first detection of vascular problems. In the absence of other biochemical markers, the present study aimed to evaluate the predictive and diagnostic role of hsCRP in stroke. The study consisted of 50 patients of acute stroke admitted in Gauhati Medical College and Hospital. The control population consisted of two groups - 50 age and sex matched controls with hypertension (Hypertensive control group) and 50 age and sex matched controls with no obvious disease constituted the Normal control group. hsCRP levels were measured in all the groups and compared statistically. hsCRP is an acute phase reactant whose concentration rises in stroke as well as in those at risk. The rise may be identified even before the appearance of risk factors. Hence, hsCRP may be useful as a predictive and diagnostic marker in stroke.

    Full Text Available Background. Chronic nature of the nasal polyps, tendency to recurrence, and lack of satisfying treatment need the diagnostic’s parameters which show early inflammatory state as ferritin and hs-CRP. The Aim of Study. Assessment of hs-CRP and ferritin blood levels in nasal polyps patients in evaluation of treatment efficacy. Methods. All 38 patients were divided into 2 groups. Group I included 19 patients with anti-inflammatory therapy 2 weeks after surgery. Group II included 19 patients without anti-inflammatory therapy 2 weeks after surgery. The levels of hs-CRP and ferritin have been assessed before and 2 and 6 weeks after surgical treatment. Results. Research showed statistically significant difference of ferritin’s concentration between examined groups 6 weeks after surgery (P<0.05 and statistically significant difference of hs-CRP concentration 2 and 6 weeks after surgery (P<0.05. Conclusion. (1 The analysis of serum ferritin and hs-CRP concentrations can be useful in early postoperative detection of inflammatory state in patients with nasal polyps and for the effectiveness of therapy. (2 Lack of correlation between mean ferritin and hs-CRP serum levels, at each diagnostic and monitoring stage, shows that they are independent and cannot be determined interchangeably.

    Full Text Available Atheromatosis develops as a result of a chronic inflammatory process of the arteries. Inflammatory biomarkers, particularly high-sensitivity C-reactive protein (hsCRP, positively correlate with atheromatosis risk factors and can be used to estimate and predict the risk of cardiovascular events. The purpose of this study was to evaluate the relationship between hsCRP concentration and BMI, body composition, classical risk factors for cardiovascular diseases, energy expenditure for physical activity (WEE and  ·VO2max. 166 volunteers (78 women and 88 men were included in the examinations. Their mean age was 20.2±0.9 years. Health condition was described by the following variables: smoking, WEE,  ·VO2max, body mass index (BMI, waist-to-hip ratio (WHR, fat mass (FM, fat-free mass (FFM, lipid profile, hsCRP, glucose and insulin concentration, and insulin resistance. Between the subgroups created on the basis of hsCRP concentration, in quartiles 1 to 3 and quartile 4, a comparative analysis was carried out. 79.5�0of women and 69.3�0of men had hsCRP values within the references ranges. Moderately high values were found in 14.1�0of women and 22.7�0of men and high in 6.4�0and 7.9�20respectively. Mean values of BMI, FFM, WHR, WEE,  ·VO2max, glucose and triglyceride concentration, and TC/HDL index were significantly lower, while FM and HDL were significantly higher, in women than in men. In the quartile 4 subgroup compared to the quartile 1-3 subgroup, we found significantly lower HDL concentration and a tendency for higher values of BMI (p=0.06 and TC (p=0.07 as well as higher percentages of smoking among men. In young, physically active, healthy persons, serum concentration of hsCRP is not related to physical activity or  ·VO2max.

    Objective: To investigate the clinical usefulness of determination of serum SA, CEA and CRP levels in patients with colorectal cancer. Methods: Serum SA (with colorimetry), CEA (with CLIA) and CRP (with ILIA) levels were measured in 120 patients with colo-rectal cancer. Results: (1) Serum SA, CEA and CRP levels increased significantly as the disease stage advanced from Duke A through Duke D. (2) As the malignancy of the growth advanced from well-differentiated to anaplastic, the serum SA and CRP levels increased significantly while the reverse was true for serum CEA levels. (3) In 68 post-operative patients followed 1-5 years, the serum levels of SA, CEA and CRP were significantly higher in the patients with recurrence (n=29) than those in patients without recurrence (n=39) (P<0.01). Conclusion: Serum SA CEA and CRP levels were closely related to the disease process in patients with colo-rectal cancer. (authors)

    Nova Scotia Duck Tolling Retrievers (NSDTRs) are a dog breed often affected by immune-mediated rheumatic disease (IMRD), a disorder characterised by chronic stiffness and joint pain. Most, but not all, dogs with IMRD, have antinuclear antibodies (ANA), which are also commonly present in the autoimmune disease systemic lupus erythematosus (SLE). The clinical and diagnostic findings of IMRD indicate that it is an SLE-related disorder. C-reactive protein (CRP), an acute phase protein, is a quantitative marker of inflammation for many diseases and is used for diagnosing and monitoring systemic inflammation in both humans and dogs. However, in human SLE, CRP concentrations are often elevated but correlate poorly with disease activity; they can be low in individual patients with active disease. The aim of the study was to investigate CRP in a group of NSDTRs with the SLE-related disorder IMRD. The hypothesis was that CRP concentrations would be increased in dogs with IMRD compared to healthy dogs, but that the increase would be mild. Serum CRP concentrations were measured in 18 IMRD-affected NSDTRs and 19 healthy control NSDTRs using two different canine-specific CRP assays. Dogs with IMRD and ANA had higher CRP concentrations than the control dogs, but the concentrations were below the clinical decision limit for systemic inflammation for most of the IMRD dogs. These results indicate that CRP concentrations were increased in dogs with IMRD and ANA, but the increase was mild, similar to what has been observed in human SLE.

    Concentration of 137 Cs, 134 Cs and potassium were measured in several higher fungi and in substrates, soils, woods and litters in some Kanto and the Koshin districts, Japan, following the Chernobyl accident during October to November 1989. 137 Cs concentrations in fungi were in the range of 0.7-101 Bq kg -1 · fresh. Maximum 137 Cs level in them was observed in Boletopsis leucomelas (Pers.: Fr.) Fayod. Significantly higher levels of concentration ratios of 137 Cs in fungi to substrates (e.g.; 137 Cs concentration · fresh in fungus/ 137 Cs concentration · dry in soil), 10 -1 to 10 x 10 -1 , were found nearly 10 to 1000 times as much as leaf vegetables, root crops and potatoes to substrates. It was confirmed that levels of concentration ratios of potassium were similar to those of 137 Cs. In all fungi, 134 Cs which released from the Chernobyl accident and is not present in nuclear weapons fallout was not detected. (author)

    Women with polycystic ovary syndrome (PCOS) often suffer from obesity and insulin resistance. The role of proinsulin, which is known to be an indicator of fertility outcomes in PCOS women, and that of adiponectin, in the pathogenesis of PCOS is not well elucidated. Our objective was to determine proinsulin, adiponectin, hsCRP and other hormonal and metabolic parameters in PCOS women before and after metformin treatment. Two PCOS groups of patients of reproductive age (90 lean and 88 obese or overweight) with two control groups, adjusted for body mass index (BMI), were compared at baseline. 32 PCOS women were studied at baseline, after three and six months of metformin (1,000 mg/day) treatment. Clinical, anthropometric, biochemical and hormonal parameters were assessed. Proinsulin and hsCRP levels were the highest in obese PCOS women and were statistically different than in lean PCOS women (proinsulin: 11.4 v. 6.9 pmol/L; hsCRP 2.46 v. 0.47 mg/L, p treatment only in obese PCOS women. PCOS, when accompanied by obesity, is associated with elevated proinsulin concentrations, which correlates with higher hsCRP and increased FAI. Proinsulin level decreases due to metformin treatment. Our results suggest that obese or overweight PCOS and lean PCOS are characterised by different hormonal and metabolic parameters and have a different response to metformin treatment.

    Cocaine is a well-known risk factor for acute cardiac events, but the effects in users outside of acute events are less clear. We investigated a possible association between cocaine use and the concentration of a novel biomarker for cardiac stress and heart failure, ST2. A case-control study was conducted to compare ST2 concentrations by the presence of cocaine in patients presenting for care, but not cardiac care, at an urban safety net hospital. In samples taken from 100 cocaine-positive and 100 cocaine-negative patients, the presence of cocaine was associated with ST2 concentrations>35ng/mL. Serum concentrations of benzoylecgonine, a major cocaine metabolite, were significantly correlated with ST2 concentrations. Cocaine use is associated with subclinical cardiac stress and damage outside of acute cardiac events. This information could add to better stratification of cocaine users with elevated ST2 concentrations who may be at higher risk for developing heart failure and other cardiac complications.

    Elevation of serum high sensitivity C-reactive protein (hs-CRP) level has been demonstrated as a risk factor for varying diseases, as well as a biomarker for predicting recovery after operation of lumber disc herniation. Our objective was to investigate the relationship between serum hs-CRP and sacroiliac (SI) joint inflammation in patients with undifferentiated spondyloarthritis (uSpA). In this retrospective study, we enrolled patients with uSpA who underwent hs-CRP testing between January 2007 and September 2013. Serum hs-CRP was analyzed at our central laboratory. All enrolled patients underwent skeletal scintigraphic scan with quantitative sacroiliac measurement. A total of 29 patients were enrolled with mean age 32.27 years and female:male ratio of 6:23. Pearson's correlation coefficient showed a significant difference between hs-CRP in serum and SI/S ratio in uSpA, particularly the middle part of the sacroiliac joint, either right side or left side. The significantly high concentration of serum hs-CRP might indicate a systemic inflammatory response to flare-up of the SI joint and might be an indicator of SI inflammation in uSpA.

    Read, D.

    2003-01-01

    An international research project has been established by the IAEA to evaluate the potential of natural radioelement concentrations and fluxes as alternative safety indicators in the assessment of radioactive waste disposal. The Finnish regulatory agency STUK is contributing to this study in the form of a report series dealing specifically with geochemical and hydrological recycling of trace elements in the stable Fennoscandian shield environment. In parallel, STUK has embarked on the development of a coupled chemical transport model based on previous work undertaken in Russia. The two initiatives are closely linked and should provide STUK with many of the tools necessary for evaluating future Posiva submissions. In order to prepare for these activities, the information required for modelling needs to be specified and the application methodology refined. This report examines the major factors that will need to be considered. Implicit in the approach is the requirement for formal testing against data from geochemical systems, including uranium-thorium ore bodies and emissions from groundwater springs and thermal spas. Although many natural analogue projects have been undertaken over the years, few of these studies specifically formulated the link to safety assessment and not all are directly applicable to the Finnish case. Nevertheless, there is a considerable body of data available from Finland, much of which has yet to be processed. A comprehensive data set exists for Palmottu and is now being re-examined to ensure that it can be exploited to its full potential. The Cu-U deposit at Hyrkkoelae provides a useful adjunct. Quantifying the effects of a repository heat source emplaced in a region of low ambient geothermal gradient is difficult. Recourse will necessarily be made to investigations at thermal spas elsewhere in Europe but first the transferability of these data needs to be assessed. The usefulness of natural indicators extends well beyond comparison of

    Full Text Available Objective. We evaluated the association between four polymorphisms in the CRP gene with circulating levels of C-reactive protein (CRP, type 2 diabetes (T2D, obesity, and risk score of coronary heart disease. Methods. We studied 402 individuals and classified them into four groups: healthy, obese, T2D obese, and T2D without obesity, from Guerrero, Southwestern Mexico. Blood levels of CRP, glucose, cholesterol, triglycerides, and leukocytes were measured. Genotyping was performed by PCR/RFLP, and the risk score for coronary heart disease was determined by the Framingham's methodology. Results. The TT genotype of SNP rs1130864 was associated with increased body mass index and T2D patients with obesity. We found that the haplotype 2 (TGAG was associated with increased levels of CRP (β=0.3; 95%CI: 0.1, 0.5; P=0.005 and haplotype 7 (TGGG with higher body mass index (BMI (β=0.2; 95%CI: 0.1, 0.3; P<0.001. The risk score for coronary heart disease was associated with increased levels of CRP, but not with any polymorphism or haplotype. Conclusions. The association between the TT genotype of SNP rs1130864 with obesity and the haplotype 7 with BMI may explain how obesity and genetic predisposition increase the risk of diseases such as T2D in the population of Southwestern Mexico.

    Evidence regarding the role of mercury and aluminum in the pathogenesis of Alzheimer's disease (AD) remains controversial. The aims of our project were to investigate the content of the selected metals in brain tissue samples and the use of a specific mathematical transform to eliminate the disadvantage of a strong positive skew in the original data distribution. In this study, we used atomic absorption spectrophotometry to determine mercury and aluminum concentrations in the hippocampus and associative visual cortex of 29 neuropathologically confirmed AD and 27 age-matched controls. The Box-Cox data transformation was used for statistical evaluation. AD brains had higher mean aluminum concentrations in the hippocampus than controls (0.357 vs. 0.090 μg/g; P = 0.039) after data transformation. Results for mercury were not significant. Original data regarding microelement concentrations are heavily skewed and do not pass the normality test in general. A Box-Cox transformation can eliminate this disadvantage and allow parametric testing.

    Full Text Available Abstract Background Animal and human studies suggest that inflammation and malnutrition are common in acute kidney injury (AKI patients. However, only a few studies reported CRP, a marker of inflammation, albumin, prealbumin and cholesterol, markers of nutritional status were associated with the prognosis of AKI patients. No study examined whether the combination of inflammatory and nutritional markers could predict the mortality of AKI patients. Methods 155 patients with hospital-acquired AKI were recruited to this prospective cohort study according to RIFLE (Risk, Injury, Failure, Lost or End Stage Kidney criteria. C-reactive protein (CRP, and the nutritional markers (albumin, prealbumin and cholesterol measured at nephrology consultation were analyzed in relation to all cause mortality of these patients. In addition, CRP and prealbumin were also measured in healthy controls (n = 45, maintenance hemodialysis (n = 70 and peritoneal dialysis patients (n = 50 and then compared with AKI patients. Results Compared with healthy controls and end-stage renal disease patients on maintenance hemodialysis or peritoneal dialysis, patients with AKI had significantly higher levels of CRP/prealbumin (p 28 days. Similarly, the combined factors including the ratio of CRP to albumin (CRP/albumin, CRP/prealbumin and CRP/cholesterol were also significantly higher in the former group (p p = 0.027 while the others (CRP, albumin, prealbumin, cholesterol, CRP/albumin and CRP/cholesterol became non-significantly associated. The hazard ratio was 1.00 (reference, 1.85, 2.25 and 3.89 for CRP/prealbumin increasing according to quartiles (p = 0.01 for the trend. Conclusions Inflammation and malnutrition were common in patients with AKI. Higher level of the ratio of CRP to prealbumin was associated with mortality of AKI patients independent of the severity of illness and it may be a valuable addition to SOFA score to independent of the severity of illness and it may be a

  20. CRP-Cyclic AMP Regulates the Expression of Type 3 Fimbriae via Cyclic di-GMP in Klebsiella pneumoniae.

    Ching-Ting Lin

    Full Text Available Klebsiella pneumoniae is the predominant pathogen isolated from liver abscesses of diabetic patients in Asian countries. However, the effects of elevated blood glucose levels on the virulence of this pathogen remain largely unknown. Type 3 fimbriae, encoded by the mrkABCDF genes, are important virulence factors in K. pneumoniae pathogenesis. In this study, the effects of exogenous glucose and the intracellular cyclic AMP (cAMP signaling pathway on type 3 fimbriae expression regulation were investigated. The production of MrkA, the major subunit of type 3 fimbriae, was increased in glucose-rich medium, whereas cAMP supplementation reversed the effect. MrkA production was markedly increased by cyaA or crp deletion, but slightly decreased by cpdA deletion. In addition, the mRNA levels of mrkABCDF genes and the activity of PmrkA were increased in Δcrp strain, as well as the mRNA levels of mrkHIJ genes that encode cyclic di-GMP (c-di-GMP-related regulatory proteins that influence type 3 fimbriae expression. Moreover, the activities of PmrkHI and PmrkJ were decreased in ΔlacZΔcrp strain. These results indicate that CRP-cAMP down-regulates mrkABCDF and mrkHIJ at the transcriptional level. Further deletion of mrkH or mrkI in Δcrp strain diminished the production of MrkA, indicating that MrkH and MrkI are required for the CRP regulation of type 3 fimbriae expression. Furthermore, the high activity of PmrkHI in the ΔlacZΔcrp strain was diminished in ΔlacZΔcrpΔmrkHI, but increased in the ΔlacZΔcrpΔmrkJ strain. Deletion of crp increased the intracellular c-di-GMP concentration and reduced the phosphodiesterase activity. Moreover, we found that the mRNA levels of multiple genes related to c-di-GMP metabolism were altered in Δcrp strain. These indicate that CRP regulates type 3 fimbriae expression indirectly via the c-di-GMP signaling pathway. In conclusion, we found evidence of a coordinated regulation of type 3 fimbriae expression by the CRP

    For us, the chief benefit of the CRP will be validation of multidimensional fluid dynamics capabilities for analysis of outlet plenum temperature distributions. As reactor designers seek new fuel handling features to reduce costs, upper internal structure configurations are becoming more compact, and higher fidelity analysis techniques are required to assess thermal stresses. Argonne currently has 1) a reactor systems analysis code with an experimentally-based model for plenum stratification, 2) the COMMIX code (parent of the JAEA AQUA code), and 3) commercial fluid dynamics analysis codes. It is anticipated that all or some combination of these capabilities will be employed to perform the CRP analysis

    This report concerns site-specific data achieved during the studies of four Finnish candidate sites for nuclear fuel repository. The aims are to examine the level of radioactive concentrations (U, Rn, K, Rb, Cs, Ra, Th), their sources and their fluxes at different sites and at different depths, and whether differences in chemical conditions result from the geology or hydrogeology. The sites cover virtually the formation history of Finnish Precambrian bedrock and differ geochemically significantly. Romuvaara represents Archean basement gneisses with low K and U contents. Proterozoic migmatitic mica gneisses at Olkiluoto represent a very reducing geochemical environment with graphite and sulphides. Oxidising conditions have characterised the formation of early synkinematic granitoids at Kivetty and as well as anorogenic rapakivi granite Haestholmen. Particularly the rapakivi granite is enriched with incompatible elements such as K, Rb, U and Th. Hydrogeologically the sites differ as well. The inland sites, Romuvaara and Kivetty, have been above the highest shoreline since the retreat of the ice of the Weichselian glaciation, whereas the coastal sites have been below sea level. Hydraulic gradient is also higher inland than on shore. The contents of radioactive elements vary significantly between the sites and between deep and shallow groundwaters. Uranium concentrations at each site decrease mainly with the increasing depth, and they correlate relatively with bedrock contents between the sites. However, the observed exceptionally low contents are considered to result from a short water-rock interaction time in shallow groundwaters at Kivetty and from actively reducing groundwater conditions in deep groundwaters at Olkiluoto. Radon contents correlate mainly with U-concentrations, suggesting that Rn derives predominantly from dissolved U. Potassium and rubidium concentrations correlate with salinity, indicating that their main source is seawater or ancient brine

    Appendectomy is one of the commonest procedures in surgery. In spite of various investigations used to improve the accuracy of diagnosis, the rate of normal appendices removed is still about 15-30%. Many studies have investigated the role of C-reactive protein (CRP) in acute appendicitis, but with conflicting results. In a prospective, double blind study, blood for the measurement of serum C-reactive protein was collected pre-operatively from 192 children before going to the operating theatre for appendectomy. The histopathology was grouped into positive (acute appendicitis) and negative (normal appendix) and this was correlated with CRP values. CRP was normal in 14 out of 33 negative explorations (normal appendix on histopathology). The specificity and sensitivity of serum CRP was 42% and 91% respectively. The predictive value of a positive (raised CRP) and negative (normal CRP) test is 88% and 48% respectively. We conclude that neither raised nor normal CRP value is helpful in the diagnosis of acute appendicitis. CRP is not a good tool for helping the surgeon make the diagnosis of appendicitis and it should not be measured in suspected appendicitis.

  8. High-normal levels of hs-CRP predict the development of non-alcoholic fatty liver in healthy men.

    Directory of Open Access Journals (Sweden)

    Jieun Lee

    Full Text Available We performed a follow-up study to address whether high sensitivity C-reactive protein (hs-CRP levels within the normal range can predict the development of non-alcoholic fatty liver disease (NAFLD in healthy male subjects. Among15347 male workers between 30 and 59 years old who received annual health check-ups in 2002, a NAFLD-free cohort of 4,138 was followed through December 2009. Alcohol consumption was assessed with a questionnaire. At each visit, abdominal ultrasonography was performed to identify fatty liver disease. The COX proportional hazard model was used to evaluate the relationship between hs-CRP and incident NAFLD. During the follow-up period, 28.8% (1191 of 4138 of participants developed NAFLD. The hazard ratios of NAFLD were increased by hs-CRP categories within the normal range in the non-adjusted model and age-adjusted model. After adjusting for age, exercise, smoking, BMI, systolic BP, triglyceride, and fasting glucose, these incidences were only increased between the lowest and the highest hs-CRP categories. The risk for NAFLD increased as the hs-CRP level increased (p< 0.001. As the hs-CRP level increased within the healthy cohort, the risk of developing NAFLD increased. This trend remained true even if the hs-CRP level remained within the normal range. hs-CRP can be used as a predictor of NAFLD, as well as other obesity-associated diseases. Therefore, individuals with higher hs-CRP levels (even within the normal range may require appropriate follow-up and management to prevent NAFLD development.

    Objective: To determine the concentration of C-reactive protein in pre- and post-operative serum samples of brain tumour patients in order to detect the potential risks of post-operative infections. Methods: Serum C-reactive protein was measured on pre- and post-operative Day 1, Day 2 and Day 7 in 18 patients who underwent surgery for brain tumours. The study was performed at the Neurosurgical Ward, Jinnah Postgraduate Medical Centre, Karachi, from May 2007 to April 2008. Mean pre-operative patients and control values were compared using Mann-Whitney or Wilcoxon tests for comparing between pre- and post-operative values. P-value was considered significant at 5.0mg/L but no statistically significant difference was found when compared with healthy controls, with mean 4.4+-6.6 and 0.9+-0.7, respectively. Significantly raised serum concentrations were observed in all post-operative samples when compared with pre-operative samples. Serum CRP concentrations significantly increased post-operatively on Day 1, with mean value of 102.9+-82.0mg/L (p<0.0005), and further increased on Day 2 with mean value of 166.9+-128.1mg/L (p<0.0005), but declined on Day 7, with mean value of 42.7+-63.6mg/L (p<0.005). Conclusion: Pre-operative serum C-reactive protein concentrations of 28% of the patients were elevated, suggesting an association with brain tumours. Post-operative serum concentrations were significantly higher than those noted before the surgery. Absence of a fall of concentration from peak value on post-operative Day 2 or a secondary rise from post-operative Day 7 could be alarming for inter-current infection. (author)

    Allexiviruses are economically important garlic viruses that are involved in garlic mosaic diseases. In this study, we characterized the allexivirus cysteine-rich protein (CRP) gene located just downstream of the coat protein (CP) gene in the viral genome. We determined the nucleotide sequences of the CP and CRP genes from numerous allexivirus isolates and performed a phylogenetic analysis. According to the resulting phylogenetic tree, we found that allexiviruses were clearly divided into two major groups (group I and group II) based on the sequences of the CP and CRP genes. In addition, the allexiviruses in group II had distinct sequences just before the CRP gene, while group I isolates did not. The inserted sequence between the CP and CRP genes was partially complementary to garlic 18S rRNA. Using a potato virus X vector, we showed that the CRPs affected viral accumulation and symptom induction in Nicotiana benthamiana, suggesting that the allexivirus CRP is a pathogenicity determinant. We assume that the inserted sequences before the CRP gene may have been generated during viral evolution to alter the termination-reinitiation mechanism for coupled translation of CP and CRP.

    Increasing atmospheric CO 2 concentration not only has a direct impact on plants but also affects plant-pathogen interactions. Due to economic and health-related problems, special concern was given thus in the present work to the effect of elevated CO 2 (750 μmol mol -1 ) level on the Fusarium culmorum infection and mycotoxin contamination of wheat. Despite the fact that disease severity was found to be not or little affected by elevated CO 2 in most varieties, as the spread of Fusarium increased only in one variety, spike grain number and/or grain weight decreased significantly at elevated CO 2 in all the varieties, indicating that Fusarium infection generally had a more dramatic impact on the grain yield at elevated CO 2 than at the ambient level. Likewise, grain deoxynivalenol (DON) content was usually considerably higher at elevated CO 2 than at the ambient level in the single-floret inoculation treatment, suggesting that the toxin content is not in direct relation to the level of Fusarium infection. In the whole-spike inoculation, DON production did not change, decreased or increased depending on the variety × experiment interaction. Cooler (18 °C) conditions delayed rachis penetration while 20 °C maximum temperature caused striking increases in the mycotoxin contents, resulting in extremely high DON values and also in a dramatic triggering of the grain zearalenone contamination at elevated CO 2 . The results indicate that future environmental conditions, such as rising CO 2 levels, may increase the threat of grain mycotoxin contamination.

  15. Higher prices at Canadian gas pumps: international crude oil prices or local market concentration? An empirical investigation

    There is little consensus on whether higher retail gasoline prices in Canada are the result of international crude oil price fluctuations or local market power exercised by large vertically-integrated firms. I find that although both increasing local market concentration and higher average monthly wholesale prices are positively and significantly associated with higher retail prices, wholesale prices are more important than local market concentration. Similarly, crude oil prices are more important than the number of local wholesalers in determining wholesale prices. These results suggest that movements in gasoline prices are largely the result of input price fluctuations rather than local market structure. (author)

    Traditional diagnostic tests for chronic diseases are expensive and require a specialized laboratory, therefore limiting their use for point-of-care (PoC) testing. To address this gap, we developed a method for rapid and low-cost C-reactive protein (CRP) detection from blood by integrating a paper-based microfluidic immunoassay with a smartphone (CRP-Chip). We chose CRP for this initial development because it is a strong biomarker of prognosis in chronic heart and kidney disease. The microfluidic immunoassay is realized by lateral flow and gold nanoparticle-based colorimetric detection of the target protein. The test image signal is acquired and analyzed using a commercial smartphone with an attached microlens and a 3D-printed chip–phone interface. The CRP-Chip was validated for detecting CRP in blood samples from chronic kidney disease patients and healthy subjects. The linear detection range of the CRP-Chip is up to 2 μg/mL and the detection limit is 54 ng/mL. The CRP-Chip test result yields high reproducibility and is consistent with the standard ELISA kit. A single CRP-Chip can perform the test in triplicate on a single chip within 15 min for less than 50 US cents of material cost. This CRP-Chip with attractive features of low-cost, fast test speed, and integrated easy operation with smartphones has the potential to enable future clinical PoC chronic disease diagnosis and risk stratification by parallel measurements of a panel of protein biomarkers.

As the role of homocysteine (Hcys, folate, and CRP has been considered in some autoimmune diseases. Objectives: To evaluate homocysteine, folate and CRP level in AA. Methods: This study was performed on 29 patients who had AA for at least 6 months affecting more than 20% of scalp, and 32 healthy controls. Levels of serum Hcys, blood high-sensitivity CRP, and RBC folate were measured in all subjects. Results: The mean level of RBC folate was significantly lower in the patient group than that in controls (P < 0.001. Also, the level of RBC folate was significantly lower in patients with extensive forms of disease (alopecia totalis/alopecia universalis in comparison with more localized form (patchy hair loss (P < 0.05. Patients with higher "Severity of Alopecia Total" (SALT score had lower RBC folate, as well. Serum Hcys and blood high-sensitivity CRP levels did not show a significant difference in two groups. Conclusion: Patients with alopecia areata have lower level of RBC folate which is in negative correlation with both severity and extension of AA.

    To explore the pathogenesis and provide evidence for the diagnosis, therapy and prognosis of acute myocardial infarction (AMI) by observing the levels of brain natriuretic peptide (BNP), endothelins (ET), C-reactive protein (CRP) and atrial natriuretic peptide (ANP) in plasma of the patients, BNP, ET, CRP and ANP levels in plasma of 46 AMI patients before and after therapy and 30 normal controls were detected by ELISA and immunoradiometric assay, respectively. Results showed that there were significant differences in BNP, ET, CRP and ANP levels in patients with AMI before and after therapy (P 0.05) after thrombolysis and other supporting therapy, the decreased BNP, ET and CRP were still significantly higher than those of control ( P<0.05). The changes of BNP, ANP, ET and CRP indicate that they involved in the occurrence and development of AMI, especially in the formation and disruption of atheromatous plaque and thrombosis. So the detection of BNP, ANP, ET and CRP levels was significant to the diagnosis, therapy and prognosis judgement

    An electrochemical impedance immunosensing method for the detection and quantification of C-reactive protein (αCRP) in phosphate buffered saline (PBS) is demonstrated. The protein antibody, Ab-αCRP, has been covalently immobilized on a platform comprising of electrochemically deposited 3-mercaptopropionic acid-capped gold nanoparticles Au(MPA)-polypyrrole (PPy) nanocomposite film of controlled thickness onto an indium tin oxide-coated glass plate. The free carboxyl groups present on the nanocomposite film have been used to site-specifically immobilize the Ab-αCRP biomolecules through a stable acyl amino ester intermediate generated by N-(3-dimethylaminopropyl)-N'-ethyl carbodiimide hydrochloride and N-hydroxysuccinimide. The nanocomposite film was characterized by atomic force microscopy, high-resolution transmission electron microscopy, Fourier transform infrared spectroscopy, and electrochemical techniques. The bioelectrode was electrochemically analyzed using modified Randles circuit in terms of constant phase element (CPE), electron transfer resistance (R et), and Warburg impedance (Z w). The value of n, a CPE exponent used as a gauge of heterogeneity, for the Au-PPy nanocomposite film was found to be 0.56 which is indicative of a rather rough morphology and porous structure. A linear relationship between the increased ∆R et values and the logarithmic value of protein antigen, Ag-αCRP, concentrations was found in the range of 10 ng to 10 μg mL(-1) with a R et sensitivity of 46.27 Ω cm(2)/decade of [Ag-αCRP] in PBS (pH 7.4).

    Although clinical use of recombinant human erythropoietin (rHuEPO) since 1989 has improved anemia in most end-stage renal disease patients, there are still many hemodialysis patients unable to maintain an adequate hematocrit (HCT) without large doses of rHuEPO. This suggests that anemia is not solely a consequence of rHuEPO deficiency, but may be due to other factors including functional iron deficiency. Since the optimal prescription for iron replacement is not yet known, we evaluated the effect of intravenous iron dextran (IVFe) infusion on serum ferritin (SFer) concentration and rHuEPO dose. Our objective was to raise and maintain serum ferritin concentrations to 2 different levels above the National Kidney Foundation Dialysis Outcome Quality Initiative standard of 100 ng/ml to determine whether, and by what degree rHuEPO dose could be lowered. HD patients on i.v. rHuEPO with a SFer concentration > or = 70 ng/ml and an HCT of requirements.

    Full Text Available Introduction: Neonatal sepsis is the most common cause of death in newborns in developing countries. Prompt diagnosis is the critical determinant in its outcome. As manifestations are often vague, clinically it is difficult to differentiate sepsis from non-infective conditions. Timely diagnosis is important as delay in initiation of antimicrobials can prove fatal. On the other hand empirical use of antibiotics not only increases the risk of antibiotic resistance but also delays the diagnosis of true condition. Procalcitonin (PCT has been well evaluated in late onset sepsis but data pertaining to Early Onset Sepsis (EOS are still lacking. We compared the diagnostic value of PCT and CRP (C-Reactive Protein in EOS. Aim: To compare the diagnostic value of serum PCT and CRP in early onset sepsis. Materials and Methods: It was a prospective observational study conducted in Neonatal Intensive Care Unit of the Department of Paediatrics, Dr.S.N. Medical College, Jodhpur, India. All neonates delivered in hospitals attached to this medical college or referred here within 7 days of life and having ≥2 perinatal risk factors for sepsis or displaying clinical sepsis were included in the study. All enrolled neonates were subjected to sepsis screen, PCT levels and blood culture at birth or admission which ever was the earliest. PCT levels ≥ 0.5 ng/ml and CRP levels above 8mg/l were considered positive for EOS. Results: Sensitivity and negative predictive value of PCT were higher than CRP (90.12% vs. 50.62% and 93.33% vs. 79.06% respectively. Also it had a higher positive predictive value of 40.56% than CRP where it was 37.61%. CRP was more specific (68.95% vs. 51.4% with overall higher diagnostic accuracy (0.64 vs. 0.61 in comparison to PCT. Conclusion: PCT is more sensitive and has a higher negative predictive value than CRP in early onset sepsis. Higher positive predictive value and specificity of CRP suggest that, PCT should not be used alone rather

    To explore the clinical significance the serum levels of N-Terminal proB-Type natriuretic peptide (NT-proBNP) and high-sensitivity C-reactive protein (hs-CRP) in patients with acute coronary syndrome,the serum levels of NT-proBNP and hs-CRP in patients and normal controls were determined by ECi Immunity Analyzer and radioimmunoassay respectively. The results showed that the serum levels of NT-proBNP and hs-CRP in patients with acute coronary syndrome were significantly higher than that of controls (P<0.05). The diagnostic specificity for acute coronary syndrome was 100% by combined detection of NT-proBNP and hs-CRP. The results suggest that the combined detection of serum NT-proBNP and hs-CRP levels are very important to evaluate heart function in patients with acute coronary syndrome. (authors)

    The need to explore structure in high-dimensional clouds of data points that may concentrate near (possibly nonlinear) manifolds of lower dimension led to the current development of three new approaches. The first is a computer-graphic system (PRIM'79) that facilitates interactive viewing and manipulation of an ensemble of points. The other two are automatic procedures for separating a cloud into more manageable pieces. One of these (BIDEC) performs successive partitioning of the cloud by use of hyperplanes; the other (Cake Maker) explores expanding sequences of neighborhoods. Both procedures provide facilities for examining the resulting pieces and the relationships among them

    Growth and productivity in important crop plants is limited by the inefficiencies of the C3 photosynthetic pathway. Introducing CO2-concentrating mechanisms (CCMs) into C3 plants could overcome these limitations and lead to increased yields. Many unicellular microautotrophs, such as cyanobacteria and green algae, possess highly efficient biophysical CCMs that increase CO2 concentrations around the primary carboxylase enzyme, Rubisco, to enhance CO2 assimilation rates. Algal and cyanobacterial CCMs utilize distinct molecular components, but share several functional commonalities. Here we outline the recent progress and current challenges of engineering biophysical CCMs into C3 plants. We review the predicted requirements for a functional biophysical CCM based on current knowledge of cyanobacterial and algal CCMs, the molecular engineering tools and research pipelines required to translate our theoretical knowledge into practice, and the current challenges to achieving these goals. © The Author 2017.

    Exclusively breastfed infants born to obese mothers have previously been shown to gain less weight by 1-month postpartum than infants of normal-weight mothers. Our hypothesis is that human milk composition and volume may differ between obese and normal-weight mothers. To compare human milk leptin, macronutrient concentration, and volume in obese and normal-weight mothers. Mother and infant characteristics were studied as secondary aims. This cross-sectional observational study compared 50 obese mothers matched for age, parity, ethnic origin, and educational level with 50 normal-weight mothers. Leptin, macronutrient human milk concentration, and milk volume were determined at 1 month in exclusively breastfed infants. Mother characteristics and infant growth were recorded. Human milk leptin concentration was higher in obese mothers than normal-weight mothers (4.8±2.7 vs. 2.5±1.5 ng.mL-1, pobese and normal-weight mothers in protein, lipid, carbohydrate content, and volume, nor in infant weight gain. Leptin concentration was higher in the milk of obese mothers than that of normal-weight mothers, but macronutrient concentration was not. It remains to be established whether the higher leptin content impacts on infant growth beyond the 1-month of the study period.

    2017-01-01

    OBJECTIVES Like any other health-related disorder, irritable bowel syndrome (IBS) has a differential distribution with respect to socioeconomic factors. This study aimed to estimate and decompose educational inequalities in the prevalence of IBS. METHODS Sampling was performed using a multi-stage random cluster sampling approach. The data of 1,850 residents of Kish Island aged 15 years or older were included, and the determinants of IBS were identified using a generalized estimating equation regression model. The concentration index of educational inequality in cases of IBS was estimated and decomposed as the specific inequality index. RESULTS The prevalence of IBS in this study was 21.57% (95% confidence interval [CI], 19.69 to 23.44%). The concentration index of IBS was 0.20 (95% CI, 0.14 to 0.26). A multivariable regression model revealed that age, sex, level of education, marital status, anxiety, and poor general health were significant determinants of IBS. In the decomposition analysis, level of education (89.91%), age (−11.99%), and marital status (9.11%) were the three main contributors to IBS inequality. Anxiety and poor general health were the next two contributors to IBS inequality, and were responsible for more than 12% of the total observed inequality. CONCLUSIONS The main contributors of IBS inequality were education level, age, and marital status. Given the high percentage of anxious individuals among highly educated, young, single, and divorced people, we can conclude that all contributors to IBS inequality may be partially influenced by psychological factors. Therefore, programs that promote the development of mental health to alleviate the abovementioned inequality in this population are highly warranted. PMID:28171714

    Nutrition during fetal life and early childhood is thought to play a crucial role in the risk for developing metabolic syndrome and cardiovascular diseases in the future adult and branched-chain amino acids (BCAA) intake may play a role in the development of obesity. The aim of this study was to compare the breast milk amino acid profiles of obese and normal weight (control) breast-feeding mothers. Fifty obese and 50 control breast-feeding mothers were enrolled. Age and parity were similar in both groups. Breast milk samples were collected at the end of the first month of lactation. Free amino acid (FAA) concentrations in breast milk were determined by ultra-performance liquid chromatography tandem mass spectrometry. Comparisons between groups were performed using a two-tailed paired t test. We analyzed 45 breast milk samples from each group. Body mass index was 34.3 ± 3.9 kg/m(2) in the obese group and 21.6 ± 1.4 kg/m(2) in the control group (P milk of obese mothers (95.5 ± 38.2 μM versus 79.8 ± 30.9 μM; P = 0.037), as was tyrosine concentration (13.8 ± 7.1 μM versus 10.6 ± 5.2 μM; P = 0.016). The mature breast milk of obese mothers contained 20% more BCAA and 30% more tyrosine than breast milk of control mothers. Whether altered breast milk FAA profile affects metabolic risk in the breast-fed child remains to be explored. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available TNF-α is a pleiotropic cytokine that is considered as a primary modifier of inflammatory and immune reaction in response to various inflammatory diseases and tumour. We investigated levels of TNF-α in 43 radicular cysts and 15 odontogenic keratocysts, obtained from patients undergoing surgery, under local anaesthesia, and after aspiration of cystic fluid from non-ruptured cysts. TNF-α is elevated in both cysts’ fluid, but higher values were found in radicular cysts in comparison to keratocysts. The significantly higher concentration of TNF-α was associated with smaller radicular cysts, higher protein concentration, higher presence of inflammatory cells in peri cystic tissues, and the degree of vascularisation and cysts wall thickness (Mann-Whitney U-test, p<0.05. No correlation was found based on these parameters in odontogenic keratocyst, but all cysts have detectable concentrations of TNF-α. We here for the first time present that a difference in the concentration of TNF-α exists between these two cystic types.

    2007-01-01

    The IAEA has initiated a Coordinated Research Project (CRP) on 'Studies of Advanced Reactor Technology Options for Effective Incineration of Radioactive Waste'. The overall objective of the CRP, performed within the framework of IAEA's Nuclear Power Technology Development Section's Technical Working Group on Fast Reactors (TWG-FR), is to increase the capability of Member States in developing and applying advanced technologies in the area of long-lived radioactive waste utilization and transmutation. More specifically, the final goal of the CRP is to deepen the understanding of the dynamics of transmutation systems, especially systems with high minor actinide content. Currently, 20 institutions from 15 member states and one international organization are participating in this CRP. The current author list comprises the participants of the last CRP Vienna meeting. The CRP concentrates on the assessment of the transient behaviour of various transmutation systems. For a sound assessment of the transient and accident behaviour, neutron kinetics and dynamics methods and codes have to be qualified, especially as the margins for the safety relevant neutronics parameters are generally becoming small in a transmutation system. Hence, the availability of adequate and qualified methods for the analysis of the various systems is an important point of the exercise. A benchmarking effort between the codes and nuclear data used for the analyses has been performed, which will help specifying the range of validity of methods, and also formulate requirements for future theoretical and experimental research. Should transient experiments become available during the course of the CRP, experimental benchmarking work will also be pursued

    A modern fuel performance analysis code FAIR has been developed for analysing high burnup fuel pins of water/heavy water cooled reactors. The code employs finite element method for modelling thermo mechanical behaviour of fuel pins and mechanistic models for modelling various physical and chemical phenomena affecting the behaviour of nuclear reactor fuel pins. High burnup affects such as pellet thermal conductivity degradation, enhanced fission gas release and radial flux redistribution are incorporated in the code FAIR. The code FAIR is capable of performing statistical analysis of fuel pins using Monte Carlo technique. The code is implemented on BARC parallel processing system ANUPAM. The code has recently participated in an International Atomic Energy Agency (IAEA) coordinated research program (CRP) on fuel modelling at extended burnups (FUMEX). Nineteen agencies from different countries participated in this exercise. In this CRP, spread over a period of three years, a number of high burnup fuel pins irradiated at Halden reactor are analysed. The first phase of the CRP is a blind code comparison exercise, where the computed results are compared with experimental results. The second phase consists of modifications to the code based on the experimental results of first phase and statistical analysis of fuel pins. The performance of the code FAIR in this CRP has been very good. The present report highlights the main features of code FAIR and its performance in the IAEA CRP on FUMEX. 14 refs., 5 tabs., ills

    Research activities focused on field studies at the Palmottu U-Th mineralisation at Nummi-Pusula in southwestern Finland in order to increase the data on groundwater chemistry of the overburden, to gather additional information of the Quaternary deposit concentrations of the previously recognised Eastern Flow System and Palmottu Brook valley. Also U inventories were estimated for a 300 m x 500 m x 250 bedrock block. From the Palmottu uranium-thorium-mineralisation there are a lot of geochemical data available from mineral phases, bedrock, peat, soil cover, lake sediments, groundwater both in the overburden and in bedrock. Especially data about the uranium concentrations in different media is comprehensive. This data can be used for the PA repository performance assessment and related calculations. The main important contributions for the performance assessment of repositories for radioactive waste are summarized in the following: 1) there are indications in the oxygen isotope composition of the groundwater, which suggest that the site may have been subjected to deep (several hundred metres) penetration of glacial melt water. This melt water does not appear to have changed the reducing conditions prevailing below the upper hydraulically active zone. Another possible process, capable to generate the depleted oxygen isotope values is a freezing front under permafrost conditions, 2) Modelling of the redox and pH controls in a flow system supported that the rock would have sufficient redox buffering capacity to counteract deep penetration of oxidising conditions. Moreover, measured present-day redox potentials demonstrate that if oxidising conditions had penetrated to depth, the conditions have been restored to reducing, 3) Based on the occurrence of young uranophanes and uranium accumulations in association with fracture calcites, it can be concluded that a continuous alteration and oxygenating process is in progress at Palmottu. This process was also manifested by

    The association between alpha-1 antitrypsin (AAT) deficiency and colorectal cancer (CRC) is currently controversial. The present study compares AAT serum concentrations and gene frequencies between a group of CRC patients and a control group of healthy unrelated people (HUP). 267 CRC subjects (63% males, 72 ± 10 years old) were enlisted from a Hospital Clinic setting in Asturias, Spain. The HUP group comprised 327 subjects (67% males, mean age 70 ± 7.5 years old) from the same geographical region. Outcome measures were AAT serum concentrations measured by nephelometry, and AAT phenotyping characterization by isoelectric focusing. Significantly higher serum concentrations were found among CRC (208 ± 60) than in HUP individuals (144 ± 20.5) (p = 0.0001). No differences were found in the phenotypic distribution of the Pi*S and Pi*Z allelic frequencies (p = 0.639), although the frequency of Pi*Z was higher in CRC (21%) than in HUP subjects (15%). The only statistically significant finding in this study was the markedly higher AAT serum concentrations found in CRC subjects compared with HUP controls, irrespective of whether their Pi* phenotype was normal (Pi*MM) or deficient (Pi*MS, Pi*MZ and Pi*SZ). Although there was a trend towards the more deficient Pi* phenotype the more advanced the tumor, the results were inconclusive due to the small sample size. Consequently, more powerful studies are needed to reach firmer conclusions on this matter

    Full Text Available Background: Pulmonary arterial hypertension secondary to untreated left-to-right shunt defects leads to increased pulmonary blood flow, endothelial dysfunction, increased pulmonary vascular resistance, vascular remodelling, neointimal and plexiform lesions. Some recent studies have shown that inflammation has an important role in the pathophysiology of pulmonary arterial hypertension. Aims: The aim of this study is to evaluate serum pentraxin 3 and high sensitive (hs-C reactive protein (hs-CRP levels in children with severe pulmonary arterial hypertension (PAH secondary to untreated congenital heart defects and evaluate the role of inflammation in pulmonary hypertension. Study Design: Cross sectional study. Methods: After ethics committee approval and receiving consent from parents, there were 31 children were selected for the study with severe PAH, mostly with a left-to-right shunt, who had been assessed by cardiac catheterisation and were taking specific pulmonary vasodilators. The control group consisted of 39 age and gender matched healthy children. After recording data about all the patients including age, gender, weight, haemodynamic studies and vasodilator testing, a physical examination was done for all subjects. Blood was taken from patients and the control group using peripheral veins to analyse serum Pentraxin 3, N-terminal pro-Brain Natriuretic Peptide (NT-ProBNP and hs-CRP levels. Serum Pentraxin-3 levels were measured by enzyme linked immunosorbent assay (ELISA and expressed as ng/mL. Serum hs-CRP levels were measured with an immunonephelometric method and expressed as mg/dL. The serum concentration of NT-proBNP was determined by a chemiluminescent immunumetric assay and expressed as pg/mL. Results: Serum Pentraxin- 3 levels were determined to be 1.28±2.12 (0.12-11.43 in the PAH group (group 1 and 0.40±0.72 (0.07-3.45 in group 2. There was a statistically significant difference between the two groups (p<0.01. Serum hs-CRP levels

    Full Text Available Background and aims. Recent epidemiological studies have shown that individuals with periodontitis have a significantly higher risk of developing coronary heart disease, which might be attributed to the complex microbiota in the dental plaque. Periodontopathogens have been reported as risk factors for cardiovascular disease. This study evaluated association of chronic periodontitis and periodontopathogens with CRP in systemically healthy Serbian adults. Materials and methods. Serum C-reactive protein levels were measured in 24 patients with moderate periodontitis, 26 patients with severe periodontitis, and 25 periodontally healthy subjects. Periodontal health indicators included gingival bleeding on probing and periodontal disease status. Patients with moderate periodontitis had low attachment loss and pocket depths of 5 mm. The control group with healthy gingiva had gingival sulcus of 5 mol/L was greater in the higher clinical AL group compared to the group with less attachment loss. Presence of periodontopathogens was also associated with elevated CRP levels and poor periodontal status. Conclusions. PD and subgingival periodontopathogens are associated with increased CRP levels. These findings suggest that periodontal infection may contribute to systemic inflammatory burden in otherwise healthy individuals.

    In this study, C-reactive protein (CRP) was detected by monitoring of LSPR shift promoted by precipitation of 4-chloro-1-naphthol (4-CN). The precipitation occurred by horseradish peroxide (HRP) catalyst which is modified at CRP-detection antibody utilized in sandwich enzyme-linked immunosorbent assay (ELISA) on gold nano bipyramid (GNBP) substrate. Due to 4-CN precipitates which are located nearby the surface of GNBP, local refractive index (RI) and molecular density were greatly increased. This phenomenon eventually induced strong spectral red-shift of absorption band of GNBP. An excellent linear relationship (R2=0.9895) between the LSPR shift and CRP concentration was obtained in the range from 100 pg/mL to 100 ng/mL and limit of detection (LOD) was reached to 87 pg/mL.

    Irisin, a recently identified myokine, is implicated in protecting mice from obesity. This study was designed to examine the relation of irisin levels in serum and synovial fluid (SF) with the radiographic severity of osteoarthritis (OA). Our study included 215 patients with knee OA. Irisin levels in serum and SF were evaluated using an enzyme-linked immunosorbent assay. The progression of OA was assessed using Kellgren-Lawrence grading system. Knee OA patients had lower serum irisin concentrations and increased serum C-reactive protein (CRP) levels compared with healthy controls. There were markedly decreased irisin levels in both the serum and the SF, as well as increased serum CRP levels of knee OA patients with Kellgren and Lawrence (KL) grade 4 compared with patients classified as KL grade 2 and 3. Furthermore, patients with KL grade 3 showed markedly reduced serum and SF levels of irisin, as well as increased serum CRP levels compared with patients classified as KL grade 2. Irisin levels in serum and SF of knee OA patients were negatively correlated with disease severity evaluated by KL grading criteria. Irisin levels in the serum and SF of knee OA patients were negatively correlated with disease severity evaluated by the radiographic KL grading criteria.

    Full Text Available Abstract Background Obesity, characterised by increased fat mass and is currently regarded as a pro-inflammatory state and often associated with increased risk of cardiovascular diseases (CVD including Myocardial infarction. There is an upregulation of inflammatory markers such as interleukin-6, interleukin-6 receptor and acute phase protein CRP in Acute Myocardial Infarction (AMI patients but the exact mechanism linking obesity and inflammation is not known. It is of our interest to investigate if serum leptin (ob gene product is associated with AMI and correlated with inflammatory proteins namely Interleukin-6 (IL-6 and high sensitivity - C reactive protein (hs-CRP. Results Serum leptin levels were significantly higher in AMI patients when compared to Non-CVD controls. IL-6 and hs-CRP were also elevated in the AMI group and leptin correlated positively with IL-6 and hs-CRP. Incidentally this is the first report from Chennai based population, India. Conclusions The strong correlation between serum levels of leptin and IL-6 implicates an involvement of leptin in the upregulation of inflammatory cytokines during AMI. We hypothesise that the increase in values of IL-6, hs-CRP and their correlation to leptin in AMI patients could be due to participation of leptin in the signaling cascade after myocardial ischemia.

    In patients with systemic hypertension, microalbuminuria is a marker of endothelial damage and is associated with an increased risk for cardiovascular disease. To determine the factors that may lead to the occurrence of microalbuminuria in hypertensive patients with serum creatinine lower than 1.5 mg/dL. This cross-sectional study included 133 Brazilians with essential hypertension followed up at a hypertension outpatient clinic. Those with serum creatinine higher than 1.5 mg/dL, as well as those with diabetes mellitus, were excluded. Systolic and diastolic blood pressures were measured, and body mass index (BMI) and GFR estimated by using the CKD-EPI formula were calculated. The serum levels of the following were assessed: CysC, creatinine, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, C-reactive protein (CRP) and fasting glucose. Microalbuminuria was determined in 24-hour urine. Hypertensive patients were classified according to the presence of one or more criteria for metabolic syndrome. In a multiple regression analysis, the serum levels of CysC and CRP, the atherogenic index log TG/HDLc and the presence of three or more criteria for metabolic syndrome were positively correlated with microalbuminuria (r{sup 2}: 0.277, p < 0.05). CysC, CRP, log TG/HDLc, and the presence of three or more criteria for metabolic syndrome, regardless of serum creatinine, were associated with microalbuminuria, an early marker of kidney damage and cardiovascular risk in patients with essential hypertension.

    Objective: To explore the relationship between the presence and severity of post-MI depression and the increased inflammatory activity, as marked by the serum levels of interleukin-6 (IL-6) and C-reactive protein (CRP) after myocardial infarction. Methods: Serum IL-6 and CRP levels were measured in 58 AMI patients within 36 hours after onset of event. Depression was evaluated by self-reporting standardized questionnaire, using a validated Chinese version of Hospiatla Anxiety and Depression Scale (HADS)-Depression Subscale (7 items) within 7 days. Demographic and medical data including LVEF, NYHA cardiac function grading, atherosclerosis severity shown from angiography as well as cardiac risk factors were recorded. Results: Serum levels of IL-6 and CRP were higher in depressive AMI patients than those in non-depressive ones (0.93 ± 0.64 vs 0.48 ± 0.37 ng/L, P<0.05 and 0.96 ± 0.41 vs 0.47 ± 0.26 mg/dL, P<0.05). Neither levels of IL-6 nor HADS-D scores were found to be correlated to the severity of atherosclerosis shown in angiography. Conclusion: Presence and severity of post-MI depression is associated with increased activity of inflammation in patients after myocardial infarction. (authors)

    In patients with systemic hypertension, microalbuminuria is a marker of endothelial damage and is associated with an increased risk for cardiovascular disease. To determine the factors that may lead to the occurrence of microalbuminuria in hypertensive patients with serum creatinine lower than 1.5 mg/dL. This cross-sectional study included 133 Brazilians with essential hypertension followed up at a hypertension outpatient clinic. Those with serum creatinine higher than 1.5 mg/dL, as well as those with diabetes mellitus, were excluded. Systolic and diastolic blood pressures were measured, and body mass index (BMI) and GFR estimated by using the CKD-EPI formula were calculated. The serum levels of the following were assessed: CysC, creatinine, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, C-reactive protein (CRP) and fasting glucose. Microalbuminuria was determined in 24-hour urine. Hypertensive patients were classified according to the presence of one or more criteria for metabolic syndrome. In a multiple regression analysis, the serum levels of CysC and CRP, the atherogenic index log TG/HDLc and the presence of three or more criteria for metabolic syndrome were positively correlated with microalbuminuria (r 2 : 0.277, p < 0.05). CysC, CRP, log TG/HDLc, and the presence of three or more criteria for metabolic syndrome, regardless of serum creatinine, were associated with microalbuminuria, an early marker of kidney damage and cardiovascular risk in patients with essential hypertension

    The Conservation Reserve Program (CRP) is a voluntary program that is available to agricultural producers to help protect environmentally sensitive or highly erodible land. Management disturbances of CRP grasslands generally are not allowed unless authorized to provide relief to livestock producers during severe drought or a similar natural disaster (i.e., emergency haying and grazing) or to improve the quality and performance of the CRP cover (i.e., managed haying and grazing). Although CRP grasslands may not be hayed or grazed during the primary bird-nesting season, these disturbances may have short-term (1 yr after disturbance) and long-term (≥2 yr after disturbance) effects on grassland bird populations. We assessed the effects of haying on 20 grassland bird species in 483 CRP grasslands in 9 counties of 4 states in the northern Great Plains, USA between 1993 and 2008. We compared breeding bird densities (as determined by total-area counts) in idle and hayed fields to evaluate changes 1, 2, 3, and 4 years after haying. Haying of CRP grasslands had either positive or negative effects on grassland birds, depending on the species, the county, and the number of years after the initial disturbance. Some species (e.g., horned lark [Eremophila alpestris], bobolink [Dolichonyx oryzivorus]) responded positively after haying, and others (e.g., song sparrow [Melospiza melodia]) responded negatively. The responses of some species changed direction as the fields recovered from haying. For example, densities for common yellowthroat (Geothlypis trichas), sedge wren (Cistothorus platensis), and clay-colored sparrow (Spizella pallida) declined the first year after haying but increased in the subsequent 3 years. Ten species showed treatment × county interactions, indicating that the effects of haying varied geographically. This long-term evaluation on the effects of haying on breeding birds provides important information on the strength and direction of changes in

    Bones and cartilage of two species of diving ducks: the scaup Aythya marila (n = 24) and the pochard A. ferina (n = 24) were studied. Scaup is protected in Poland where it spends only the winter, while pochard is a game bird, abundant and breeding in Poland. In winter, the two species form large flocks off the southern coast of the Baltic, particularly in the Szczecin Lagoon where they were collected for this study. The bones and cartilage (trachea) were assayed for concentrations (dry weight-based) of three essential metals: iron (Fe), copper (Cu), and zinc (Zn); concentrations of the two toxic metals: lead (Pb) and cadmium (Cd) were assayed as well. These hard tissues of the two species showed the following order of metal concentrations Zn > Fe > Pb > Cu > Cd. In scaup and pochard bones, the respective geometric mean concentrations of Zn, Fe, Pb, Cu, and Cd were 94.4 and 102.0; 20.2 and 24.7; 6.2 and 9.6; 0.19 and 0.26; 0.114 and 0.162 mg/kg. The levels of all the metals in cartilage (Zn 149.1 and 165.8; Fe 58.4 and 116.3; Pb 10.6 and 14.9; Cu 1.41 and 3.31; Cd 0.144 and 0.175 mg/kg, respectively) were higher than in the bones of A. marila and A. ferina. However, statistically significant differences were found in respect to the essential metals only (Zn, Fe, Cu). The inter-species comparisons showed the two species to differ in their cartilage concentrations of Fe, Cu, Zn, and Cd and in their bone concentrations of Pb and Cd. In each case, the pochard exhibited higher concentrations of metals. This study showed distinct differences between trace element accumulation by two heavily mineralised avian body parts: leg bones (tarsometatarsus) and cartilage (trachea). The results are in agreement with data reported by other workers who analysed trace metals in cartilaginous and bone components of the femoral head in homoiotherm vertebrates, including humans. Therefore it is important that intra- and inter-species comparisons of hard biological components be based on

    Breast cancer, the most commonly diagnosed cancer among women and leading cause of cancer-related deaths worldwide, exhibits aggressive behavior in indigenous African women evidenced by high histologic grade tumours with low hormone receptor positivity. Aggressive breast cancers grow quickly, easily metastasize and recur and often have unfavourable outcomes. The current study investigated candidate genes that may regulate tumour aggression in Ghanaian women. We hypothesize that increased expression and function of certain genes other than the widely-held view attributing breast cancer aggression in African populations to their younger population age may be responsible for the aggressive nature of tumours. Employing ELISA, we assayed for vimentin and death-associated protein kinase 1 (DAPK1) from thawed archived (stored at -80 °C) serum samples obtained from 40 clinically confirmed Ghanaian breast cancer patients and 40 apparently healthy controls. Patients' clinical records and tumour parameters matching the samples were retrieved from the database of the hospital. ANOVA was used to compare means of serum protein concentration among groups while Chi-square analysis was used for the categorical data sets with p -value ≤0.05 considered significant. Multiple logistic regression analysis was conducted to determine the association between protein concentration and tumour parameters. Of the 80 samples, 27 (33.8%) and 53 (66.2%) were from young (<35 years) and old (≥35 years), respectively. Vimentin and DAPK1 concentration were higher in patients than controls with higher levels in "young" age group than "old" age group. Vimentin concentration was highest in grade 3 tumours followed by grade 2 and 1 but that for DAPK1 was not significant. For vimentin, tumour area strongly correlated with tumour grade ( r  = 0.696, p  < 0.05) but weakly correlated with tumour stage ( r  = 0.420, p  < 0.05). Patient's age correlated with DAPK1 concentration ( r  = 0

    2001-01-01

    The effects of magnesium ion concentration on the rate of electron transport in isolated pea thylakoids were investigated in the pH range from 4.0 up to 8.0. In the absence of magnesium ions in the medium and in the presence of 5 mM MgCl2 in the experiments not only without added artificial acceptors but also with ferricyanide or methylviologen as an acceptor, this rate had a well-expressed maximum at pH 5.0. It was shown that, after depression to minimal values at pH 5.5-6.5, it gradually rose with increasing pH. An increase in magnesium ion concentration up to 20 mM essentially affected the electron transfer rate: it decreased somewhat at pH 4.0-5.0 but increased at higher pH values. At this magnesium ion concentration, the maximum rate was at pH 6.0-6.5 and the minimum, at pH 7.0. Subsequent rise upon increasing pH to 8.0 was expressed more sharply. The influence of high magnesium ion concentration on the rate of electron transport was not observed in the presence of gramicidin D. It was found that without uncoupler, the changes in the electron transfer rate under the influence of magnesium ions correlated to the changes in the first-order rate constant of the proton efflux from thylakoids. It is supposed that the change in the ability of thylakoids to keep protons by the action of magnesium ions is the result of electrostatic interactions of these ions with the charges on the external surface of membranes. A possible role of regulation of the electron transport rate by magnesium ions in vivo is discussed.

    Diabetes is undoubtedly one of the most challenging health problems in 21st century. Understanding the pathogenesis and preventing long term complications have been major goals of research in diabetes mellitus (DM). Research in the past few years has linked oxidative stress and inflammation to beta cell dysfunction. Aim of this study is to evaluate serum gamma-glutamyl transferase (GGT) activity (marker of oxidative stress) and high sensitivity C reactive protein (hsCRP) level (an inflammatory marker) in type 2 DM subjects with good and poor glycemic control. Further, we investigated correlation between serum GGT and hsCRP level with glycemic control (FBS, PP2BS, HbA1c) in subjects. A cross sectional study consists of 150 patients out of them 50 patients having type 2 DM with good control (Group II), 50 patients with type 2 DM with poor control (Group III) and 50 normal healthy control (Group I) were selected. Serum GGT, serum hsCRP, FBS, PP2BS, HbA1c, and other biochemical investigations include serum liver enzymes and lipids were measured. Mean serum GGT and hsCRP concentration were statistically significantly higher in group III patients compared to group I and group II subjects as well as increased in group II compared to group I (p stress and inflammation appears to be a key component and also associated with poor glycemic control and further pathogenesis of diabetes and its complications. All our finding suggesting a link between oxidative stress, inflammation and glycemic control in patient with type 2 diabetes mellitus.

    Type 2 Diabetes (T2D) and particulate air pollution are associated with inflammatory dysregulation. We assessed the modifying effects of diabetes medications on the association of C-reactive protein (CRP), a marker of inflammation, and traffic exposure in adults with T2D (n = 379). CRP concentrations were significantly positively associated with residence ≤100 m of a roadway, >100 m and ≤200 m of a roadway and increased traffic density for individuals using insulin. For individuals using oral hypoglycemic medications (OHAs), CRP was significantly negatively associated with residence >100 m - ≤200 m of a roadway and multiple roadway exposure in an interaction model. Among people with diabetes, individuals on insulin appear to be most vulnerable to the effects of traffic exposure. Disease severity among insulin users may promote the pro-inflammatory response to traffic exposure, though diabetes medications may also modify the response. Possible anti-inflammatory effects of OHAs with traffic exposure merit further evaluation. - Highlights: →We examine traffic exposure in a population with high rates of Type 2 Diabetes. →Differences in CRP were evaluated by traffic levels, medication use and type. →Those on insulin had significantly higher CRP with traffic exposure. →Interaction models demonstrated lower CRP with traffic exposure and OHA use. →Diabetes medications may modify the response to traffic exposure. - Among people with diabetes, individuals on insulin appear to be most vulnerable to the effects of traffic exposure. Diabetes medications may modify the response to traffic.

    To determine the association of CMV infection with neurocognitive performance in HIV+ adults. Cross-sectional, observational, exploratory study. Anti-CMV IgG concentrations in blood and CMV DNA copies in blood and cerebrospinal fluid (CSF) were measured in stored specimens of 80 HIV+ adults who were previously assessed with a standardized, comprehensive neurocognitive test battery. Thirty-eight were taking suppressive antiretroviral therapy (ART, HIV RNA ≤ 50 copies/mL) and 42 were not taking ART. A panel of 7 soluble biomarkers were also measured by immunoassay in CSF. Anti-CMV IgG concentrations ranged from 5.2 to 46.1 U/mL. CMV DNA was detected in 7 (8.8%) blood plasma but in none of the CSF specimens. Higher anti-CMV IgG levels were associated with older age (p=0.0017), lower nadir CD4+ T-cell count (pperformance overall (p=0.059). This correlation was present in those taking suppressive ART (p=0.0049) but not in those who were not taking ART (p=0.92). Worse neurocognitive performance remained associated with higher anti-CMV IgG levels after accounting for other covariates in multivariate models (Model p=0.0038). Detectable plasma CMV DNA was associated with AIDS (p=0.05) but not with neurocognitive performance. CMV may influence neurocognitive performance in HIV+ adults taking suppressive ART. Future clinical trials of anti-CMV therapy should help determine whether the observed relationships are causal.

    The objective of this study is to determine whether inflammatory markers (high-sensitivity C-reactive protein (Hs-CRP) and interleukin (IL)-6) early in the postpartum period contribute to the development of postpartum depression (PPD). From 4 May 2014 to 30 June 2014, all eligible women not on medication for depression giving birth at the Beijing Chao-Yang hospital were consecutively recruited and followed up for 6 months. Depression symptoms were measured with the Edinburgh Postnatal Depression Scale (EPDS), and inflammatory biomarkers (Hs-CRP and IL-6) were tested. During the study period, 296 women were enrolled and completed follow-up. In these women, 45 (15.2%) were considered as meeting the criteria for PPD. Serum levels of Hs-CRP and IL-6 in women with PPD were significantly higher than those without PPD (all P<0.0001). Receiver operating characteristics to predict PPD demonstrated areas under the curve of IL-6 of 0.861 (95% confidence interval (CI), 0.801-0.922), which was superior to Hs-CRP (0.837 (95% CI, 0.781-0.894), P<0.01). In multivariate logistic regression analysis, IL-6 and Hs-CRP were independent predictors of PPD. The present study demonstrates a strong relationship between elevated serum Hs-CRP and IL-6 levels at admission and the development of PPD within 6 months. Copyright © 2016 Elsevier Ireland Ltd.

    To examine associations of high-sensitivity C-reactive protein (CRP) levels and polygenic CRP genetic risk scores (GRS) with risk of end-stage hip or knee osteoarthritis (OA), defined as incident total hip (THR) or knee replacement (TKR) for OA. This study included a cohort of postmenopausal white, African American, and Hispanic women from the Women's Health Initiative. Women were followed from baseline to date of THR or TKR, death, or December 31, 2014. Medicare claims data identified THR and TKR. Hs-CRP and genotyping data were collected at baseline. Three CRP GRS were constructed: 1) a 4-SNP GRS comprised of genetic variants representing variation in the CRP gene among European populations; 2) a multilocus 18-SNP GRS of genetic variants significantly associated with CRP levels in a meta-analysis of genome-wide association studies; and 3) a 5-SNP GRS of genetic variants significantly associated with CRP levels among African American women. In analyses conducted separately among each race and ethnic group, there were no significant associations of ln hs-CRP with risk of THR or TKR, after adjusting for age, body mass index, lifestyle characteristics, chronic diseases, hormone therapy use, and non-steroidal anti-inflammatory drug use. CRP GRS were not associated with risk of THR or TKR in any ethnic group. Serum levels of ln hs-CRP and genetically-predicted CRP levels were not associated with risk of THR or TKR for OA among a diverse cohort of women.

    Full Text Available Raised C-reactive protein (CRP is a risk factor for type 2 diabetes. According to the Mendelian randomization method, the association is likely to be causal if genetic variants that affect CRP level are associated with markers of diabetes development and diabetes. Our objective was to examine the nature of the association between CRP phenotype and diabetes development using CRP haplotypes as instrumental variables.We genotyped three tagging SNPs (CRP + 2302G > A; CRP + 1444T > C; CRP + 4899T > G in the CRP gene and measured serum CRP in 5,274 men and women at mean ages 49 and 61 y (Whitehall II Study. Homeostasis model assessment-insulin resistance (HOMA-IR and hemoglobin A1c (HbA1c were measured at age 61 y. Diabetes was ascertained by glucose tolerance test and self-report. Common major haplotypes were strongly associated with serum CRP levels, but unrelated to obesity, blood pressure, and socioeconomic position, which may confound the association between CRP and diabetes risk. Serum CRP was associated with these potential confounding factors. After adjustment for age and sex, baseline serum CRP was associated with incident diabetes (hazard ratio = 1.39 [95% confidence interval 1.29-1.51], HOMA-IR, and HbA1c, but the associations were considerably attenuated on adjustment for potential confounding factors. In contrast, CRP haplotypes were not associated with HOMA-IR or HbA1c (p = 0.52-0.92. The associations of CRP with HOMA-IR and HbA1c were all null when examined using instrumental variables analysis, with genetic variants as the instrument for serum CRP. Instrumental variables estimates differed from the directly observed associations (p = 0.007-0.11. Pooled analysis of CRP haplotypes and diabetes in Whitehall II and Northwick Park Heart Study II produced null findings (p = 0.25-0.88.

    High plasma concentrations of ascorbic acid, a marker of fruit and vegetable intake, are associated with low risk of coronary artery disease. Whether this relationship is explained by a reduction in systemic inflammation is unclear. We investigated the relationship between ascorbic acid plasma concentration and coronary artery disease risk, and in addition whether this relationship depended on classical risk factors and C-reactive protein (CRP) concentration. We used a prospective nested case-control design. The study consisted of 979 cases and 1794 controls (1767 men and 1006 women). Increasing ascorbic acid quartiles were associated with lower age, BMI, systolic and diastolic blood pressure, and CRP concentration, but with higher HDL-cholesterol concentration. No associations existed between ascorbic acid concentration and total cholesterol concentration or LDL-cholesterol concentration. When data from men and women were pooled, the risk estimates decreased with increasing ascorbic acid quartiles such that people in the highest ascorbic acid quartile had an odds ratio for future coronary artery disease of 0.67 (95 % CI 0.52, 0.87) compared with those in the lowest quartile (P for linearity=0.001). This relationship was independent of sex, age, diabetes, smoking, BMI, LDL-cholesterol, HDL-cholesterol, systolic blood pressure and CRP level. These data suggest that the risk reduction associated with higher ascorbic acid plasma concentrations, a marker of fruit and vegetable intake, is independent of classical risk factors and also independent of CRP concentration.

    The cyclic AMP receptor protein (CRP) is a bacterial regulator that controls more than 100 promoters, including those involved in catabolite repression. In the present study, a null deletion of the crp gene was constructed for Yersinia pestis bv. microtus strain 201. Microarray expression analysis disclosed that at least 6% of Y. pestis genes were affected by this mutation. Further reverse transcription-PCR and electrophoretic mobility shift assay analyses disclosed a set of 37 genes or putative operons to be the direct targets of CRP, and thus they constitute the minimal CRP regulon in Y. pestis. Subsequent primer extension and DNase I footprinting assays mapped transcriptional start sites, core promoter elements, and CRP binding sites within the DNA regions upstream of pla and pst, revealing positive and direct control of these two laterally acquired plasmid genes by CRP. The crp disruption affected both in vitro and in vivo growth of the mutant and led to a >15,000-fold loss of virulence after subcutaneous infection but a pestis and, particularly, is more important for infection by subcutaneous inoculation. It can further be concluded that the reduced in vivo growth phenotype of the crp mutant should contribute, at least partially, to its attenuation of virulence by both routes of infection. Consistent with a previous study of Y. pestis bv. medievalis, lacZ reporter fusion analysis indicated that the crp deletion resulted in the almost absolute loss of pla promoter activity. The plasminogen activator encoded by pla was previously shown to specifically promote Y. pestis dissemination from peripheral infection routes (subcutaneous infection [flea bite] or inhalation). The above evidence supports the notion that in addition to the reduced in vivo growth phenotype, the defect of pla expression in the crp mutant will greatly contribute to the huge loss of virulence of this mutant strain in subcutaneous infection.

    BACKGROUND: The concentration of C-reactive protein (CRP) in otherwise healthy subjects has been shown to predict future risk of myocardial infarction and stroke. CRP is synthesized by the liver in response to interleukin-6, the serum concentration of which is subject to diurnal variation. METHODS: To examine the existence of a time-of-day effect for baseline CRP values, we determined CRP concentrations in hourly blood samples drawn from healthy subjects (10 males, 3 females; age range, 21-35 years) during a baseline day in a controlled environment (8 h of nighttime sleep). RESULTS: Overall CRP concentrations were low, with only three subjects having CRP concentrations >2 mg/L. Comparison of raw data showed stability of CRP concentrations throughout the 24 h studied. When compared with cutoff values of CRP quintile derived from population-based studies, misclassification of greater than one quintile did not occur as a result of diurnal variation in any of the subjects studied. Nonparametric ANOVA comparing different time points showed no significant differences for both raw and z-transformed data. Analysis for rhythmic diurnal variation using a method fitting a cosine curve to the group data was negative. CONCLUSIONS: Our data show that baseline CRP concentrations are not subject to time-of-day variation and thus help to explain why CRP concentrations are a better predictor of vascular risk than interleukin-6. Determination of CRP for cardiovascular risk prediction may be performed without concern for diurnal variation.

    Objective: To investigate the relationship between plasma TNF-α, IL-1β and CRP levels in aged patients with coronary heart disease and to define the inflammation marker which might recognize and predict acute coronary syndrome. Methods: Radioimmunoassay was used to detect plasma levels of TNF-α, IL-1β and CRP. Results: Plasma levels of TNF-α and IL-β in patients with acute coronary syndrome (ACS) were significantly higher than those in controls (p<0.05; p<0.01) and stable coronary heart disease (SCHD) (p<0.05; p<0.01). Plasma CRP levels in patients with ACS (7.99 +- 11.9 ml/L) were also significantly higher than those in controls (0.99 +- 1.5 mg/L; p<0.01) and patients with SCHD (2.71 +- 5.45 mg/L; p<0.05). There was positive correlation between CRP level and TNF-α (r=0.0545; p<0.01) as well as IL-β (r=0.31, p<0.05). Conclusion: The abnormal expression of cytokines in aged patients with coronary heart disease was correlative to inflammation marker CRP, which suggested that the abnormal expression to the occurrence of acute coronary syndrome and might serve as a marker of unstable atherosclerosis plaque

    Controlled-release permanganate (CRP) is a relatively new technology used to treat contaminated groundwater. This study tested the encapsulation of permanganate using stearic acid to realize controlled-release properties. Batch experiments were conducted to investigate the performance of manganese oxides (MnO 2 ) in the reaction between CRP and the contaminant of interest: tetrachloroethylene (PCE). The results showed that higher ionic strengths (I = 0.1 mol/L) cause earlier precipitation of MnO 2 colloids. Using CRP to degrade PCE could decrease the amount of MnO 2 colloids produced and postpone precipitation compared to raw potassium permanganate (KMnO 4 ) under high ionic strength conditions by controlling the KMnO 4 concentration in the solution. The amount of MnO 2 colloids produced and the time of precipitation depended more on the CRP grain size than on the CRP mass ratio. Controlling the KMnO 4 concentration used in the reaction could control the formation of MnO 2 precipitates in the premise of guarantee the removal rate of PCE.

    To investigate the association of serum lipids and high-sensitivity C-reactive protein (hs-CRP) with obesity in school children and to explore whether hs-CRP levels could be used to predict the presence or absence of obesity 12 months later. The subjects were school children (6-11 years old) in Japan. Blood sampling and physical measurements were performed in school (2001); low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, and hs-CRP levels were measured. Data from children who could be followed 12 months later were analyzed. Subjects weighing 20% or more over his/her standard weight were regarded as obese, and the association of obesity with serum parameters was analyzed. Data from 612 subjects were analyzed (follow-up rate, 75.4%). The mean of each serum parameter was significantly higher (inverse for HDL-C; lower) in obese than that in non-obese children. Logistic regression analysis for obesity at baseline showed that the odds ratio (OR) of hs-CRP was the highest [OR, 2.15; 95% confidence interval (CI), 1.65-2.78 for an interquartile rage (IQR) increase]; the association with triglycerides and LDL-C/HDL-C was significant. At the 12-month follow-up, the OR of high hs-CRP remained the highest of all serum parameters (2.09; 95% CI, 1.63-2.69 for an IQR increase). High levels of triglycerides, LDL-C/HDL-C, and hs-CRP increased the risk of obesity in school children. Hs-CRP is considered to be a better predictor of obesity 12 months later than is LDL-C/HDL-C.

    A variety of bacteria, including Escherichia coli, are known to enter the viable but non-culturable (VBNC) state under various stress conditions. During this state, cells lose colony-forming activities on conventional agar plates while retaining signs of viability. Diverse environmental stresses including starvation induce the VBNC state. However, little is known about the genetic mechanism inducing this state. Here, we aimed to reveal the genetic determinants of the VBNC state of E. coli. We hypothesized that the VBNC state is a process wherein specific gene products important for colony formation are depleted during the extended period of stress conditions. If so, higher expression of these genes would maintain colony-forming activities, thereby restraining cells from entering the VBNC state. From an E. coli plasmid-encoded ORF library, we identified genes that were responsible for maintaining high colony-forming activities after exposure to starvation condition. Among these, cpdA encoding cAMP phosphodiesterase exhibited higher performance in the maintenance of colony-forming activities. As cpdA overexpression decreases intracellular cAMP, cAMP or its complex with cAMP-receptor protein (CRP) may negatively regulate colony-forming activities under stress conditions. We confirmed this using deletion mutants lacking adenylate cyclase or CRP. These mutants fully maintained colony-forming activities even after a long period of starvation, while wild-type cells lost most of this activity. Thus, we concluded that the lack of cAMP-CRP effectively retains high colony-forming activities, indicating that cAMP-CRP acts as a positive regulator necessary for the induction of the VBNC state in E. coli.

    Full Text Available Abstract Background Cyclic AMP receptor protein (CRP, also known as catabolite gene activator protein (CAP, is an important transcriptional regulator widely distributed in many bacteria. The biological processes under the regulation of CRP are highly diverse among different groups of bacterial species. Elucidation of CRP regulons in cyanobacteria will further our understanding of the physiology and ecology of this important group of microorganisms. Previously, CRP has been experimentally studied in only two cyanobacterial strains: Synechocystis sp. PCC 6803 and Anabaena sp. PCC 7120; therefore, a systematic genome-scale study of the potential CRP target genes and binding sites in cyanobacterial genomes is urgently needed. Results We have predicted and analyzed the CRP binding sites and regulons in 12 sequenced cyanobacterial genomes using a highly effective cis-regulatory binding site scanning algorithm. Our results show that cyanobacterial CRP binding sites are very similar to those in E. coli; however, the regulons are very different from that of E. coli. Furthermore, CRP regulons in different cyanobacterial species/ecotypes are also highly diversified, ranging from photosynthesis, carbon fixation and nitrogen assimilation, to chemotaxis and signal transduction. In addition, our prediction indicates that crp genes in modern cyanobacteria are likely inherited from a common ancestral gene in their last common ancestor, and have adapted various cellular functions in different environments, while some cyanobacteria lost their crp genes as well as CRP binding sites during the course of evolution. Conclusion The CRP regulons in cyanobacteria are highly diversified, probably as a result of divergent evolution to adapt to various ecological niches. Cyanobacterial CRPs may function as lineage-specific regulators participating in various cellular processes, and are important in some lineages. However, they are dispensable in some other lineages.

    Full Text Available Oxidative damage to microbial hosts often occurs under stressful conditions during bioprocessing. Classical strain engineering approaches are usually both time-consuming and labor intensive. Here, we aim to improve E. coli performance under oxidative stress via engineering its global regulator cAMP receptor protein (CRP, which can directly or indirectly regulate redox-sensing regulators SoxR and OxyR, and other ~400 genes in E. coli. Error-prone PCR technique was employed to introduce modifications to CRP, and three mutants (OM1~OM3 were identified with improved tolerance via H(2O(2 enrichment selection. The best mutant OM3 could grow in 12 mM H(2O(2 with the growth rate of 0.6 h(-1, whereas the growth of wild type was completely inhibited at this H(2O(2 concentration. OM3 also elicited enhanced thermotolerance at 48°C as well as resistance against cumene hydroperoxide. The investigation about intracellular reactive oxygen species (ROS, which determines cell viability, indicated that the accumulation of ROS in OM3 was always lower than in WT with or without H(2O(2 treatment. Genome-wide DNA microarray analysis has shown not only CRP-regulated genes have demonstrated great transcriptional level changes (up to 8.9-fold, but also RpoS- and OxyR-regulated genes (up to 7.7-fold. qRT-PCR data and enzyme activity assay suggested that catalase (katE could be a major antioxidant enzyme in OM3 instead of alkyl hydroperoxide reductase or superoxide dismutase. To our knowledge, this is the first work on improving E. coli oxidative stress resistance by reframing its transcription machinery through its native global regulator. The positive outcome of this approach may suggest that engineering CRP can be successfully implemented as an efficient strain engineering alternative for E. coli.

    C-reactive protein (CRP) is a marker of arterial inflammation while lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) is related to plaque instability. The aim of this study was to evaluate the correlation between the risk of unstable plaque presenting as acute coronary syndrome (ACS) and Lp-PLA(2), and to assess the influence of statins on interpretation of Lp-PLA(2). A total of 362 consecutive patients presenting to the emergency department (ED) with acute chest pain suggestive of ACS were evaluated by cardiologists as STEMI, NSTEMI, or unstable angina, and non-ACS. Serum biomarkers measured on admission: troponin I, C-reactive protein (Abbott), and Lp-PLA(2) (DiaDexus). Four groups were defined according to the final diagnosis and history of statin medication: ACS/statin-; ACS/statin+; non-ACS/statin-; non-ACS/statin+. Lp-PLA(2) was highest in ACS/statin- group; statins decreased Lp-PLA(2) both in ACS and non-ACS of about 20 %. Lp-PLA(2) was higher in ACS patients in comparison with non-ACS patients group without respect to statin therapy (pPLA(2) predicted worse outcome (in terms of acute coronary syndrome) effectively in patients up to 62 years; limited prediction was found in older patients. C-reactive protein (CRP) failed to discriminate four groups of patients. Statin therapy and age should be taken into consideration while interpreting Lp-PLA(2) concentrations and lower cut-off values should be used for statin-treated persons.

    While the potential of plants to uptake polycyclic aromatic hydrocarbons (PAHs) is widely acknowledged, empirical evidence of the effects of this process on local atmospheric PAH concentrations and human health is tenuous. We measured gaseous PAH concentrations using passive samplers in urban tree-covered areas and adjacent open, treeless areas in a near-road environment in Finland to gain information on the ability of urban vegetation to improve air quality. The ability of urban, mostly deciduous, vegetation to affect PAHs was season dependent: during summer, concentrations were significantly higher in tree-covered areas, while in the fall, concentrations in open areas exceeded those in tree-covered areas. During winter, concentrations in tree-covered areas were either lower or did not differ from those in open areas. Results of this study imply that the commonly believed notion that trees unequivocally improve air quality does not apply to PAHs studied here. - Highlights: • Urban tree-cover increases gaseous PAH concentrations during summertime. • Elevated PAH concentrations do not clearly correspond with vegetation properties. • Tree-cover attenuates seasonal PAH concentration fluctuation. - Higher ambient gaseous PAH concentrations were detected within urban tree cover as compared to open areas during summertime.

    Full Text Available The primary purpose of this study was to identify if serum 25-hydroxyvitamin D (25(OHD concentrations predict muscular weakness after intense exercise. We hypothesized that pre-exercise serum 25(OHD concentrations inversely predict exercise-induced muscular weakness. Fourteen recreationally active adults participated in this study. Each subject had one leg randomly assigned as a control. The other leg performed an intense exercise protocol. Single-leg peak isometric force and blood 25(OHD, aspartate and alanine aminotransferases, albumin, interferon (IFN-γ, and interleukin-4 were measured prior to and following intense exercise. Following exercise, serum 25(OHD concentrations increased (p < 0.05 immediately, but within minutes, subsequently decreased (p < 0.05. Circulating albumin increases predicted (p < 0.005 serum 25(OHD increases, while IFN-γ increases predicted (p < 0.001 serum 25(OHD decreases. Muscular weakness persisted within the exercise leg (p < 0.05 and compared to the control leg (p < 0.05 after the exercise protocol. Serum 25(OHD concentrations inversely predicted (p < 0.05 muscular weakness (i.e., control leg vs. exercise leg peak isometric force immediately and days (i.e., 48-h and 72-h after exercise, suggesting the attenuation of exercise-induced muscular weakness with increasing serum 25(OHD prior to exercise. Based on these data, we conclude that pre-exercise serum 25(OHD concentrations could influence the recovery of skeletal muscle strength after an acute bout of intense exercise.

    The aim of this study was to quantify the association between the CRP value and 18 F-FDG PET vascular positivity in Takayasu arteritis (TAK) through a structured dedicated systematic review and meta-analysis. From January 2000 to December 2016, the PubMed/MEDLINE database was searched for articles specifically dealing with the assessment of vascular inflammation using 18 F-FDG PET and CRP biomarkers in TAK. Inclusion criteria for the qualitative analysis were (1) 18 F-FDG PET used to assess the disease activity, (2) The use of the ACR criteria for the diagnosis of TAK, (3) No case mixed vasculitis (i.e., no giant cell arteritis), and (4) CRP concentration and clinical disease activity available. For the meta-analysis, PET-positive and PET-negative subgroups with the corresponding CRP concentrations were generated based on per patient data. The standard mean difference, which represents the effect of the CRP concentrations on the 18 F-FDG PET vascular uptake, was computed for all studies, and then the results were pooled together. Among the 33 initial citations, nine complete articles including 210 patients fulfilled the inclusion criteria.

    The aim of this study was to quantify the association between the CRP value and {sup 18}F-FDG PET vascular positivity in Takayasu arteritis (TAK) through a structured dedicated systematic review and meta-analysis. From January 2000 to December 2016, the PubMed/MEDLINE database was searched for articles specifically dealing with the assessment of vascular inflammation using {sup 18}F-FDG PET and CRP biomarkers in TAK. Inclusion criteria for the qualitative analysis were (1) {sup 18}F-FDG PET used to assess the disease activity, (2) The use of the ACR criteria for the diagnosis of TAK, (3) No case mixed vasculitis (i.e., no giant cell arteritis), and (4) CRP concentration and clinical disease activity available. For the meta-analysis, PET-positive and PET-negative subgroups with the corresponding CRP concentrations were generated based on per patient data. The standard mean difference, which represents the effect of the CRP concentrations on the {sup 18}F-FDG PET vascular uptake, was computed for all studies, and then the results were pooled together. Among the 33 initial citations, nine complete articles including 210 patients fulfilled the inclusion criteria. Five studies found a significant correlation between the {sup 18}F-FDG PET and CRP concentration, one provided a trend towards association and three did not find any association between the two biomarkers. Six studies found a significant association between {sup 18}F-FDG PET and clinical disease activity, one found a trend towards association and the last two studies did not evaluate this correlation. The meta-analysis (121 patients) provided the following results: Standard Mean Deviation = 0.54 [0.15;0.92]; Chi{sup 2} = 3.35; I{sup 2} = 0%; Test for overall effect: Z = 2.70 (P = 0.007). The CRP concentration only moderately reflects the {sup 18}F-FDG PET vascular positivity in TAK, suggesting dissociated information.

    Full Text Available To evaluate maternal serum C-reactive protein (CRP concentrations in pregnancies complicated by preterm prelabor rupture of membranes (PPROM in relation to the presence of microbial invasion of the amniotic cavity (MIAC and/or intra-amniotic inflammation (IAI.Two hundred and eighty-seven women with singleton pregnancies complicated by PPROM between 2014 and 2016 were included in this study. Maternal blood and amniotic fluid samples were collected at the time of admission. Maternal serum CRP concentration was measured using a high-sensitivity immunoturbidimetric assay. Interleukin-6 (IL-6 concentration was measured using a point-of-care test. MIAC was diagnosed based on a positive polymerase chain reaction result for Ureaplasma species, Mycoplasma hominis, and/or Chlamydia trachomatis and for the 16S rRNA gene. IAI was characterized by an amniotic fluid IL-6 concentration of ≥ 745 pg/mL.Women with MIAC and IAI had higher maternal serum CRP concentrations than did women without (with MIAC: median 6.9 mg/L vs. without MIAC: median 4.9 mg/L; p = 0.02; with IAI: median 8.6 mg/L vs. without IAI: median 4.7 mg/L; p < 0.0001. When women were split into four subgroups based on the presence of MIAC and/or IAI, women with the presence of both MIAC and IAI had higher maternal serum CRP than did women with IAI alone, with MIAC alone, and women without MIAC and IAI (both MIAC and IAI: median: 13.1 mg/L; IAI alone: 6.0 mg/L; MIAC alone: 3.9 mg/L; and without MIAC and IAI: median 4.8 mg/L; p < 0.0001. The maternal serum CRP cutoff value of 17.5 mg/L was the best level to identify the presence of both MIAC and IAI, with sensitivity of 47%, specificity of 96%, positive predictive value of 42%, negative predictive value of 96%, and the positive likelihood ratio of 10.9.The presence of both MIAC and IAI was associated with the highest maternal serum CRP concentrations.

    Bacterial infections to anaerobic site are often hard to be treated because the activity of most of antimicrobials decreases under anaerobic conditions. However, fosfomycin rather provides a greater activity under anaerobic conditions than aerobic conditions. Previously, we found that expression of glpT and uhpT , fosfomycin symporters in enterohaemorrhagic Escherichia coli (EHEC) was upregulated by FNR, a global regulator during the anaerobiosis of the bacterium, which led to increased uptake and susceptibility to this drug. In this study, we showed that expression of glpT and uhpT is induced by CRP-cAMP, the regulator complex under both aerobic and anaerobic conditions. The activity of CRP-cAMP in EHEC was elevated under anaerobic conditions because levels of both CRP and cAMP were higher in the cells when grown anaerobically than those when grown aerobically. Results of expression study using mutants indicated that CRP-cAMP is indispensable for expression of glpT but not uhpT -whereas that of uhpT requires UhpA that is the response regulator composing of two-component system with the sensor kinase, UhpB. The CRP-cAMP protein bound to a region that overlaps RNA polymerase binding site for glpT and region upstream of UhpA binding site for uhpT . FNR bound to a region further upstream of CRP-cAMP binding site on region upstream of the glpT gene. These combined results suggested that increased antibacterial activity of fosfomycin to EHEC under anaerobic conditions is due to activation of FNR and increment of CRP-cAMP activity. Then, FNR enhances the expression of glpT activated by CRP-cAMP while CRP-cAMP and FNR cooperatively aids the action of UhpA to express uhpT to maximum level.

    Periodontal disease is a chronic infection of the gums characterised by a loss of attachment between the tooth and bone, and bone loss. C-reactive protein (CRP) elevation is a part of the acute phase response to acute and chronic inflammation. Many epidemiological studies have shown that serum CRP levels were elevated in patients with chronic periodontitis. CRP levels increase to hundreds of μg/ml within hours following infection. It out-performs erythrocyte sedimentation rate (ESR) in terms of responsiveness and specificity for inflammation. While CRP elevation is suggestive of inflammation or infection in the appropriate clinical context, it can also occur with obesity and renal dysfunction. Conversely, a lack of CRP elevation in inflammation may be seen with hepatic failure, as well as during flares of conditions such as systemic lupus erythematosus.

    Harmane (1-methyl-9H-pyrido[3,4-b]indole), a neurotoxin, may be an environmental risk factor for essential tremor (ET). Harmane and related chemicals are toxic to the cerebellum. Whether it is through this mechanism (cerebellar toxicity) that harmane leads to ET is unknown. Impaired olfaction may be a feature of cerebellar disease. To determine whether blood harmane concentrations correlate with olfactory test scores in patients with ET. Blood harmane concentrations were quantified using high performance liquid chromatography. Odor identification testing was performed with the University of Pennsylvania Smell Identification Test (UPSIT). In 83 ET cases, higher log blood harmane concentration was correlated with lower UPSIT score (rho=-0.46, p<0.001). 25/40 (62.5%) cases with high log blood harmane concentration (based on a median split) had low UPSIT scores (based on a median split) vs. 12/43 (27.9%) ET cases with low log blood harmane concentration (adjusted odd ratios (OR) 4.04, 95% confidence intervals (CI) 1.42-11.50, p=0.009). When compared with the low log blood harmane tertile, the odds of olfactory dysfunction were 2.64 times higher in cases in the middle tertile and 10.95 times higher in cases in the high tertile. In 69 control subjects, higher log blood harmane concentration was not correlated with lower UPSIT score (rho=0.12, p=0.32). Blood harmane concentrations were correlated with UPSIT scores in ET cases but not controls. These analyses set the stage for postmortem studies to further explore the role of harmane as a cerebellar toxin in ET.

    The induction of luminescence in Vibrio harveyi at the later stages of growth is controlled by a quorum-sensing mechanism in addition to nutritional signals. However, the mechanism of transmission of these signals directly to the lux promoters is unknown and only one regulatory protein, LuxR, has been shown to bind directly to lux promoter DNA. In this report, we have cloned and sequenced two genes, crp and metR, coding for the nutritional regulators, CRP (cAMP receptor protein) and MetR (a LysR homologue), involved in catabolite repression and methionine biosynthesis respectively. The metR gene was cloned based on a general strategy to detect lux DNA-binding proteins expressed from a genomic library, whereas the crp gene was cloned based on its complementation of an Escherichia coli crp mutant. Both CRP and MetR were shown to bind to lux promoter DNA, with CRP being dependent on the presence of cAMP. Expression studies indicated that the two regulators had opposite effects on luminescence: CRP was an activator and MetR a repressor. Disruption of crp decreased luminescence by about 1,000-fold showing that CRP is a major activator of luminescence the same as LuxR, whereas disruption of MetR resulted in activation of luminescence over 10-fold, confirming its function as a repressor. Comparison of the levels of the autoinducers involved in quorum sensing excreted by V. harveyi, and the crp and metR mutants, showed that autoinducer production was not significantly different, thus indicating that the nutritional signals do not affect luminescence by changing the levels of the signals required for quorum sensing. Indeed, the large effects of these nutritional sensors show that luminescence is controlled by multiple signals related to the environment and the cell density which must be integrated at the molecular level to control expression at the lux promoters.

    Objective: The aim of this study was to evaluate the concentrations of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and the degree of homeostasis model assessment-insulin resistance (HOMA-IR) in patients with morbid obesity exposed to a three-week low-calorie diet and balneotherapy. Methods: The study included 33 patients (25 females and 8 males; mean age 46 years) with body mass index (BMI) values of >40 kg/m2. Evaluations of CRP, IL-6, TNF-α, lipid profile, HOMA-IR, and fasting glucose were carried out before (baseline data) and three weeks after the treatment. The control group consisted of 20 healthy volunteers (15 females and 5 males) with a mean age of 39 years and BMI values of ≤24.9 kg/m2. Results: In the blood of patients with morbid obesity we found significantly elevated levels of CRP, TNF-α, triglycerides, HOMA-IR and fasting glucose, but a decreased level of high density lipoprotein (HDL)-cholesterol, compared with the healthy individuals. The treatment resulted in about a 9.4% reduction in body weight from 122.5 to 111.0 kg and a significant decrease in the concentration of CRP, but no change in TNF-α or IL-6. HOMA-IR was significantly reduced. Conclusions: The decrease in CRP level without changes in TNF-α or IL-6 concentrations after the low-calorie diet and balneological treatment, suggests that an essential amount of adipose tissue must be removed before proper adipocyte function is restored. The decrease in HOMA-IR indicates an improvement in insulin sensitivity, which is beneficial in obese patients. PMID:25990058

    We aimed to explore the association between self-reported leisure time physical activity (LTPA) and C-reactive protein (CRP) concentrations in men and women with and without impaired glucose tolerance (IGT). In a cross-sectional study, a random sample (n = 2,816) was examined with an oral glucose tolerance test, CRP and information about LTPA. Those with IGT or normal glucose tolerance (NGT) and CRP value ≤10 mg/L were selected (n = 2,367) for the study. An inverse association between LTPA and CRP concentrations was observed in the population (P men with IGT (P = .023) and in women with NGT. Men with IGT, reporting slight physical activity up to 4 hours a week presented significantly higher CRP concentrations than normoglycemic men (Δ0.6 mg/L, P = .004). However, this difference could not be found in men with IGT reporting more intense physical activity (Δ0.01 mg/L, P = .944). Physical inactivity seems to have greater inflammatory consequences for men (vs. women) with IGT. More importantly, although 4 hours of physical activity per week is more than the usual minimum recommendation, an even greater intensity of LTPA appears to be required to limit subclinical inflammation in men with IGT.

    Objective: To determine the correlation of C-reactive protein (CRP) with fasting triglycerides (TG) among pre-obese and obese patients without established diagnosis of coronary artery disease (CAD). Study Design: A comparative cross-sectional study. Place and Duration of Study: Mayo Hospital, Lahore, from January to June 2010. Methodology: Patients with BMI > 23 kg/m2 aged between 18 - 65 years were inducted and above variables were studied. Patients with signs of fluid retention, collagen vascular disease, CAD, patients on corticosteroids, immunomodulators or lipid lowering medications and febrile patients were not recruited. Body mass index was also determined. Independent sample t-test was applied to see the mean difference of age, CRP level and triglycerides level in relation to gender. Chisquare test was used to see the association between qualitative variables. ANOVA was applied to see CRP and fasting serum TG level in relation to BMI categories. Pearson correlation and simple linear regression was applied to see the dependency of CRP and triglycerides with BMI. P-value A = 0.05 was taken as significant. Results: Raised CRP was major finding among all groups of BMI. Most of obese and pre-obese patients were young and middle aged and belonged to pre-obese group followed by class-1 and class-2 obesity. CRP level increased with body mass index. No such trend was observed for triglycerides. There was an intermediate positive correlation between CRP and BMI and triglycerides and BMI showed a weak negative correlation. If BMI increases by 1 unit on the average, CRP rises by 0.239 times and this unit rise was significant. Whereas 1 unit rise increase in triglycerides on the average cause CRP to decrease -0.006 times but this value was insignificant. Conclusion: Raised CRP and high fasting TG were major findings in all age groups especially among young and middle aged people. Obesity, hypertriglyceridemia and raised CRP are interrelated suggesting that obesity is not

    Introduction: We evaluated the association between four polymorphisms in the CRP gene with serum C-reactive protein (CRP) levels, prevalence and severity of coronary artery disease (CAD) in type 2 diabetes mellitus (T2DM) patients. Methods: We performed coronary angiography for 308 T2DM patients and classified them into two groups: T2DM with CAD and T2DM without CAD. All patients were from Ahvaz, Iran. serum levels of CRP, glucose and lipid profile were measured. Genotyping was performed by PCR/RFLP, and the severity of coronary artery disease was determined by Gensini score. Results: The GG genotype of SNP rs279421 was associated with the increased risk of CAD (OR= 2.38; 95% CI: 1.12- 5.8; p= 0.02) and CA, TT, TA genotypes and A allele of SNP rs3091244 and GA genotypes and A allele of SNP rs3093062 were significantly associated with increased CRP levels. None of genotypes or alleles was associated with Gensini score. We found that the haplotype 7 (AGCG) was associated with decreased risk of CAD (OR= 0.11; 95% CI: 0.02, 0.66; p= 0.017) and the Gensini score was correlated with increased levels of CRP, only in CAD group. Conclusion: Although genetic polymorphisms were influenced on serum RP levels, none of the alleles and genotypes raising or falling C-reactive protein levels was consistently associated with an increased prevalence of CAD or protected from that.

    The auxin formation in a submerged culture of the xylotrophic basidiomycete Lentinus edodes (Berk.) Sing (Lentinula edodes (Berk.) Pegler) (shiitake) is studied. Biologically active substances of an indole nature are identified, "the effect of small doses" of which lies in not only the stimulation of growth of the mycelium (indole-3-acetic acid, 2 x 10(-7)-2 x 10(-4) g/l), but also in the induction of tryptophan-independent paths of auxin biosynthesis. The above-mentioned path is realized in the presence of exogenous indole (1 x 10(-3)-1 x 10(-4) g/l), as well as while inducing the biosynthesis of indole-3-acetic acid by its microadditives (1 x 10(-5)-1 x 10(-8) g/l), and is accompanied by the formation of anthranilic acid (up to 1.5 mg/l). Induction of the generative development stage ofshiitake by indole derivatives is revealed. It was found that among the studied compounds only indoleacetamide at a concentration of an order of x 10(-4) g/l in the culture fluid of L. edodes had a pronounced stimulatory effect on the formation of shiitake's brown mycelial film.

    The standard dose of imatinib for the treatment of chronic-phase chronic myeloid leukemia (CML) is 400 mg·d. A predose plasma imatinib concentration of >1 mg·L is associated with improved clinical response. This study aimed to assess the plasma imatinib and norimatinib concentrations attained in patients with chronic myeloid leukemia administered standard doses of imatinib adjusted for dose, age, sex, body weight, and response. We evaluated data from a cohort of patients treated between 2008 and 2014 with respect to dose, age, sex, body weight, and response. The study comprised 438 samples from 93 patients (54 male, 39 female). The median imatinib dose was 400 mg·d in men and in women. The plasma imatinib concentration ranged 0.1-5.0 mg·L and was below 1 mg·L in 20% and 16% of samples from men and women, respectively. The mean dose normalized plasma imatinib and norimatinib concentrations were significantly higher in women in comparison with men. This was partially related to body weight. Mixed effects ordinal logistic regression showed no evidence of an association between sex and plasma imatinib (P = 0.13). However, there was evidence of an association between sex and plasma norimatinib, with higher norimatinib concentrations more likely in women than in men (P = 0.02). Imatinib therapeutic drug monitoring only provides information on dosage adequacy and on short-term adherence; longer-term adherence cannot be assessed. However, this analysis revealed that approximately 1 in 5 samples had a plasma imatinib concentration <1 mg·L, which was suggestive of inadequate dosage and/or poor adherence and posed a risk of treatment failure. Higher imatinib exposure in women may be a factor in the increased rate of long-term, stable, deep molecular response (undetectable breakpoint cluster-Abelson (BCR-ABL) transcript levels with a PCR sensitivity of 4.5 log, MR4.5) reported in women.

    of the BARC nebulizer, already published in 1979, are described in much greater detail with many blue-print diagrams. The efficacy of and easy access to the nebulizer have been tested and established against commercially available nebulizers. The comparative studies have been conducted on aerosol lung scan images using the BARC and other nebulizers. The results of extended clinical applications are presented: the diseases investigated include COPD, bronchial obstruction, compensatory overinflation, acute pneumonia, tuberculosis, focal and diffuse interstitial fibrosis, diffuse panbronchiolitis, lung edema and bronchogenic carcinoma and metastasis. Of these, COPD was used as a model disease group, in which an analytical interpretation of scan alterations has been attempted to establish a differential diagnostic scheme of clinically related but pathologically different diseases. It was aimed at emphasizing the potential role of aerosol scan in making specific diagnosis of the individual diseases on the basis of both anatomical and physiological alterations as they are portrayed in aerosol lung scans. More clinical applications are described in association with embolism, inhalation bums and glue-sniffing. In regard with the aerosol scan technique, a modification has been introduced to improve scan image quality with enhanced resolution by maximally avoiding background noise so that the scan may provide more graphic information.

    of the BARC nebulizer, already published in 1979, are described in much greater detail with many blue-print diagrams. The efficacy of and easy access to the nebulizer have been tested and established against commercially available nebulizers. The comparative studies have been conducted on aerosol lung scan images using the BARC and other nebulizers. The results of extended clinical applications are presented: the diseases investigated include COPD, bronchial obstruction, compensatory overinflation, acute pneumonia, tuberculosis, focal and diffuse interstitial fibrosis, diffuse panbronchiolitis, lung edema and bronchogenic carcinoma and metastasis. Of these, COPD was used as a model disease group, in which an analytical interpretation of scan alterations has been attempted to establish a differential diagnostic scheme of clinically related but pathologically different diseases. It was aimed at emphasizing the potential role of aerosol scan in making specific diagnosis of the individual diseases on the basis of both anatomical and physiological alterations as they are portrayed in aerosol lung scans. More clinical applications are described in association with embolism, inhalation bums and glue-sniffing. In regard with the aerosol scan technique, a modification has been introduced to improve scan image quality with enhanced resolution by maximally avoiding background noise so that the scan may provide more graphic information. The tests that examine nonrespiratory lung functions such as mucociliary transport and lung permeability are also discussed in this monograph for the future study. In order to epitomize the ready practicability, economical aspect and excellent reproducibility of radioaerosol lung scan by using the BARC nebulizer, a forum is provided for case presentation of those who have enthusiastically participated in this CRP group study during the past 5 years.

    The purpose of this study was to determine if the US-CRP values associated with periodontal disease are risk markers for Acute Myocardial Infarction (AMI) and to determine if the US-CRP levels associated with recent AMI are higher in patients with Periodontal disease. In order to meet the goal of the study, a case control study design was conducted. The analysis sample consisted of 401 adults (30 - 75 years old), living in Bogota D.C., Colombia, from the Hospital Universitario San Ignacio, the Faculty of Dentistry at the Pontificia Universidad Javeriana, and the Fundacion Cardio Infantil. Patients with current infections, antibiotic use in the last 3 months, periodontal treatment at least six months before the baseline of this study, mouth ulcerations caused by any type of prosthesis, candidiasis, stomatitis, or less than 7 teeth in mouth were excluded. Periodontal examination for the case group and the control group was conducted by three previously calibrated examiners. Periodontal disease was diagnosed by the presence of bleeding on probing and attachment loss. The Chronic Periodontitis diagnosis was confirmed with these clinical signs, according to the 1999 Armitage classification. The assessment of the US-CRP was performed using the IMMULITE method containing one monoclonal and one polyclonal anti-CRP antibody. This method provides a measurement range of 0.1 - 500 mg/L. Statistical analysis of variables was performed with OR and confidence intervals. A multivariate analysis was performed to determine the association between the US-CRP increase, periodontal disease and acute myocardial infarction, adjusting for smoking and other confounding factors identified in the analysis. The study population was constituted by 401 patients, 56.1% (225) males, with a mean age of 52.6. When groups were compared it was observed that, in those patients with AMI and chronic severe or moderate periodontitis, 24.2% had HDL-C values lower than 40 mg/dl, 78.8% had LDL-C values

    IAEA-CRP on Radiation Doses in Diagnostic Radiology and Methods for Dose Reduction has as participants some Asian and East European countries. Indonesia is one of participants that followed the IAEA program. This paper is not a discussion of CRP-results since it will be published as a TECDOC soon. But the work on evaluation of examination frequencies, film reject rate analysis, patient dose measurements, image quality before and after Quality Control (QC) and QC itself, gave some experiences to investigators to be explored and presented. Experiences could be in the form of problems, how to solve problems and some suggestions, starting from no QC up to complicated QC to be faced in conventional radiography to CT-scan and fluoroscopy units. These valuable experiences of Indonesia are proven exercise of IAEA-CRP as a good start for next CRP or national projects in diagnostic radiology. (author)

    2013-01-01

    BACKGROUND: Low-grade inflammation is a marker for cardiovascular disease (CVD). The inflammatory biomarkers C-reactive protein (CRP) and soluble urokinase plasminogen activator receptor (suPAR) independently predict CVD. We tested the hypothesis that these biomarkers reflect different aspects...... of the inflammation associated with CVD. METHODS: We studied 2273 subjects without CVD. Log-transformed CRP and suPAR were included in general linear and logistic regression models to compare associations with measures of anthropometry and subclinical organ damage (SOD). Owing to interactions on body mass index (BMI......) (P3: 1.31 (1.16-1.47), whereas log-CRP was not (1.00 (0.89-1.11))). CONCLUSIONS: CRP is positively associated with anthropometric measures, whereas suPAR is linked to endothelial dysfunction and atherosclerosis....

    Full Text Available A controlled, parallel, randomized and comparative trial was carried out to evaluate the anti-inflammatory efficacy of IMMUNEPOTENT CRP versus ibuprofen in patients after third-molar surgery over seven days. The anti-inflammatory efficacy of IMMUNEPOTENT CRP was evaluated using the method of Amin and Laskin, and the analysis of cytokine production (IL-2, IL-4, IL-6, IL-10, TNF-α, INF-γ in saliva was done by flow cytometry. The swelling process after surgery was significant (p < 0.05 and the treatments with IMMUNEPOTENT CRP or ibuprofen controlled this process properly; no difference between the groups was found (p < 0.05. Both treatments were shown to modulate the cytokine production. These results demonstrate the anti-inflammatory activity of the natural compound IMMUNEPOTENT CRP and suggest it could be used in clinical dental practice.

    High levels of circulating C-reactive protein (CRP) have recently been linked to poor clinical outcome in various malignancies. The aim of this study was to evaluate the prognostic significance of the preoperative serum CRP level in patients with squamous cell carcinoma (SCC) of the penis. This retrospective analysis included 79 penile cancer patients with information about their serum CRP value prior to surgery who underwent either radical or partial penectomy at two German high-volume centers (Ulm University Medical Center and Hannover Medical School) between 1990 and 2010. They had a median (mean) follow-up of 23 (32) months. A significantly elevated CRP level (>15 vs. ≤ 15 mg/l) was found more often in patients with an advanced tumor stage (≥pT2) (38.9 vs. 11.6%, p=0.007) and in those with nodal disease at diagnosis (50.0 vs. 14.6%, p=0.007). However, high CRP levels were not associated with tumor differentiation (p=0.53). The Kaplan-Meier 5-year cancer-specific survival (CSS) rate was 38.9% for patients with preoperative CRP levels above 15 mg/l and 84.3% for those with lower levels (p=0.001). Applying multivariate analysis and focusing on the subgroup of patients without metastasis at the time of penile surgery, both advanced local tumor stage (≥pT2; HR 8.8, p=0.041) and an elevated CRP value (>15 mg/l; HR 3.3, p=0.043) were identified as independent predictors of poor clinical outcome in patients with penile cancer. A high preoperative serum CRP level was associated with poor survival in patients with penile cancer. If larger patient populations confirm its prognostic value, its routine use could enable better risk stratification and risk-adjusted follow-up of patients with SCC of the penis

    C-reactive protein (CRP) has evolved as an inflammatory risk marker of cardiovascular disease. Several single-nucleotide polymorphisms at the CRP locus have been found to be associated with CRP levels. The aim of the present study was to investigate CRP levels and genetic variants in etiological subtypes of ischemic stroke. The Sahlgrenska Academy Study on Ischemic Stroke (SAHLSIS) comprises 600 consecutive ischemic stroke cases (18 to 69 years) and 600 matched controls from western Sweden. Stroke subtypes were defined by the TOAST classification. Serum CRP levels were determined by a high-sensitivity immunometric assay. CRP levels were significantly higher for all ischemic stroke subtypes compared with controls, both in the acute phase and at the 3-month follow-up. After adjustment for traditional risk factors, CRP at follow-up was related to higher odds ratios (ORs) of overall ischemic stroke (OR, 1.25; 95% CI, 1.09 to 1.43) and large-vessel disease (OR, 1.48; 95% CI, 1.09 to 2.00). The CRP -286C>T>A, 1059G>C, and 1444C>T single-nucleotide polymorphisms showed significant associations with CRP levels. However, neither CRP genotypes nor haplotypes showed an association to overall ischemic stroke. This is the first large study on CRP in different TOAST subtypes in a young ischemic stroke population. CRP levels differed between etiological subtypes of ischemic stroke both in the acute phase and at the 3-month follow-up. CRP at follow-up was associated with overall ischemic stroke and the large-vessel disease subtype. Genetic variants at the CRP locus were associated with CRP levels, but no association was detected for overall ischemic stroke.

    Background: Little is known about the effects of overall dietary pattern on lead concentration. Objective: We examined the association of overall dietary patterns, derived from a semiquantitative food frequency questionnaire, with bone and blood lead concentrations. Methods: These longitudinal analyses included mostly non-Hispanic white, middle-aged-to-elderly men from the Veterans Affairs Normative Aging Study. Long-term lead exposures were measured as tibia and patella lead concentrations by using K-shell-X-ray fluorescence. Short-term lead exposures were measured as blood lead concentrations by using graphite furnace atomic absorption spectroscopy. Dietary pattern scores were derived by using factor analysis. Linear mixed-effects models were utilized to predict blood lead concentrations among 983 men, aged 44-92 y at baseline, with a total of 3273 observations (during 1987-2008). We constructed linear regression models to determine the relations between dietary patterns and bone lead concentrations among 649 participants with an age range of 49-93 y. Results: Two major dietary patterns were identified: a prudent dietary pattern, characterized by high intakes of fruit, legumes, vegetables, whole grains, poultry, and seafood; and a Western dietary pattern, characterized by high intakes of processed meat, red meat, refined grains, high-fat dairy products, French fries, butter, and eggs. After adjusting for age, smoking status, body mass index, total energy intake, education, occupation, neighborhood-based education and income level, men in the highest tertile of the Western pattern score (compared with the lowest) had 0.91 μg/dL (95% CI: 0.41, 1.42 μg/dL) higher blood lead, 5.96 μg/g (95% CI: 1.76, 10.16 μg/g) higher patella lead, and 3.83 μg/g (95% CI: 0.97, 6.70 μg/g) higher tibia lead. No significant association was detected with the prudent dietary pattern in the adjusted model. Conclusions: These findings suggest that the Western diet is associated with

    The aim of this study was to evaluate the efficacy of treatment with mud pack in knee osteoarthritis (OA) and to determine whether mud pack effects serum levels of YKL-40 and high-sensitivity C-reactive protein (hsCRP) which are reported to be biological markers for articular damage or inflammation in patients with OA. Forty-four patients with the diagnosis of knee OA assigned into two groups were treated with local natural mineral-rich mud pack or hot pack. Treatments were applied for 6 days a week for 2 weeks as a total of 12 sessions. Patients were assessed at baseline, post-treatment, and 3 months after the treatment. VAS, range of motion, 15-m walking time, WOMAC index, Nottingham Health Profile, serum YKL-40, and hsCRP levels were the outcome measures. Pain intensity and joint stiffness decreased in both groups at all follow-ups. Physical activity status was found to persist for 3 months after treatment only in mud pack group. Serum mean YKL-40 and hsCRP levels of the patients were higher compared to healthy control group. Serum YKL-40 level increased significantly only in hot pack group 3 months after the treatment (P 0.05). Mud pack and hot pack therapy were both demonstrated to be effective in symptomatic treatment of knee OA until the end of the 2-week treatment period, whereas only mud pack therapy was shown to be effective in functional status over time. In the hot pack group, increased serum YKL-40 level 3 months after the treatment might indicate persistence of cartilage degradation. Maintenance of YKL-40 level in mud pack therapy seems to slow down the progression of knee OA.

    Full Text Available Abstract Introduction Obesity increases the risk for insulin resistance and metabolic syndrome in both adults and children. FABP4 is a member of the intracellular lipid-binding protein family that is predominantly expressed in adipose tissue, and plays an important role in maintaining glucose and lipid homeostasis. The purpose of this study was to measure FABP4 plasma levels, assess FABP4 allelic variants, and explore potential associations with fasting glucose and insulin levels in young school-age children with and without obesity. Methods A total of 309 consecutive children ages 5-7 years were recruited. Children were divided based on BMI z score into Obese (OB; BMI z score >1.65 and non-obese (NOB. Fasting plasma glucose, lipids, insulin, hsCRP, and FABP4 levels were measured. HOMA was used as correlate of insulin sensitivity. Four SNPs of the human FABP4 gene (rs1051231, rs2303519, rs16909233 and rs1054135, corresponding to several critical regions of the encoding FABP4 gene sequence were genotyped. Results Compared to NOB, circulating FABP4 levels were increased in OB, as were LDL, hsCRP and HOMA. FABP4 levels correlated with BMI, and also contributed to the variance of HOMA and hsCRP, but not serum lipids. The frequency of rs1054135 allelic variant was increased in OB, and was associated with increased FABP4 levels, while the presence of rs16909233 variant allele, although similar in OB and NOB, was associated with increased HOMA values. Conclusions Childhood obesity is associated with higher FABP4 levels that may promote cardiometabolic risk. The presence of selective SNPs in the FABP4 gene may account for increased risk for insulin resistance or systemic inflammation in the context of obesity.

    Identification of associations between global DNA methylation and excess body weight (EBW) and related diseases and their modifying factors are an unmet research need that may lead to decreasing DNA methylation-associated disease risks in humans. The purpose of the current study was to evaluate the following; 1) Association between the degree of peripheral blood mononuclear cell (PBMC) L1 methylation and folate, and indicators of EBW, 2) Association between the degree of PBMC L1 methylation and folate, and insulin resistance (IR) as indicated by a higher homeostasis model assessment (HOMA-IR). The study population consisted of 470 child-bearing age women diagnosed with abnormal pap. The degree of PBMC L1 methylation was assessed by pyrosequencing. Logistic regression models specified indicators of EBW (body mass index-BMI, body fat-BF and waist circumference-WC) or HOMA-IR as dependent variables and the degree of PBMC L1 methylation and circulating concentrations of folate as the independent predictor of primary interest. Women with a lower degree of PBMC L1 methylation and lower plasma folate concentrations were significantly more likely to have higher BMI, % BF or WC (OR = 2.49, 95% CI:1.41-4.47, P = 0.002; OR = 2.49, 95% CI:1.40-4.51, P = 0.002 and OR = 1.98, 95% = 1.14-3.48 P = 0.0145, respectively) and higher HOMA-IR (OR = 1.78, 95% CI:1.02-3.13, P = 0.041). Our results demonstrated that a lower degree of PBMC L1 methylation is associated with excess body weight and higher HOMA-IR, especially in the presence of lower concentrations of plasma folate.

    Full Text Available Background: Preeclampsia is a multisystem disorder of unknown etiology characterized by development of hyperten­sion to the extent of 140/90 mm of Hg or more with proteinuria after the 20th gestational week in a previously normoten­sive and non protein uric women. According to the National High blood presure Working group (NHBPEP and Ameri­can college of obstetricans and Gynecologiests (ACOG hypertension in pregnancy is defined as a diastolic blood pressure of 90 mm Hg or higher after 20 weeks of gestation in a woman with previously normal blood pressure (NHBPEP, 2000; ACOG, 2002. If the disease is allowed to progress to the HELLP syndrome or eclampsia, maternal morbidity and mortality increases. The majority of perinatal losses are related to placental insufficiency, which causes intrauterine growth retardation, prematurity associated with preterm delivery, or abruptio placentae. Objectives: This study tried to explore the effect of serum C reactive protein concentration in preeclamptic women and its effect on pregnancy outcome.Methods: This case control study included 60 third trimester pregnant women (30 normotensive and 30 preeclamptic who attended Department of Obstetrics and Gynaecology, BIRDEM and DMCH, during July 2009 and June 2010. Estimation of serum C reactive protein (CRP concentrations was done by liquid phase immunoprecipitation assay and turbulometry at DMC.Results: Mean (±SD age showed no significant difference between groups; however, BMI, SBP, DBP and CRP were significantly (P<0.001 high in case group. Gravidity and ANC showed no significant variation between groups. CRP concentration was significantly high case group. Gestational age was significantly low in case group resulting in higher preterm delivery. No significant variation was observed regarding fetal outcome; however, birth weight was significantly low and neonatal complication was also significantly high in case group.Conclusion: CRP concentration was high in

    The aim of this study was to investigate the efficacy of radiofrequency ablation in the treatment of pediatric arrhythmia and to assess the changes in serum interleukin-6 (IL-6) and hs-CRP levels after treatment. Hundred and six children with tachyarrhythmia who were admitted to Xuzhou Children's Hospital from November, 2014 to December, 2015 were recruited for study. The efficacies of radiofrequency in the treatment of different types of arrhythmia were analyzed. Successful ablation was found in 104 cases (98.11%) and recurrence was found in 7 cases (6.73%). Among 62 cases of atrioventricular reentrant tachycardia (AVRT), successful ablation was found in 60 cases (96.77%) and recurrence was found in 3 cases (4.84%). Among 33 cases of atrioventricular nodal reentrant tachycardia (AVNRT), successful ablation was found in 33 cases (100%) and recurrence was found in 2 cases (6.06%). Among 5 cases of ventricular tachycardia (VT), successful ablation was found in 5 cases (100%) and no recurrence was found. Among 4 cases of atrial tachycardia (AT), successful ablation was found in 4 cases (100%) and recurrence was found in 1 case (25%). Among 2 cases of atrial flutter (AFL), successful ablation was found in both (100%) and recurrence was found in 1 case (50%). After operation, the levels of IL-6 and hs-CRP were increased and were continually increased within 6 h after operation. The levels of IL-6 and hs-CRP at 24 h after operation were reduced but still higher than preoperative levels. The duration of radiofrequency and ablation energy were positively correlated with the levels of IL-6 and hs-CRP, while the number of discharges was not significantly correlated with either. In conclusion, radiofrequency ablation is a safe and effective treatment for pediatric arrhythmia. Postoperative monitoring of IL-6 and hs-CRP levels is conducive to understanding postoperative myocardial injury and inflammatory response.

    The complex of the cyclic AMP receptor protein (CRP) and cAMP is an important transcriptional regulator of numerous genes in prokaryotes. The transport of mannitol through the phosphotransferase systems (PTS) is regulated by the CRP-cAMP complex. The aim of the study is to investigate how the CRP-cAMP complex acting on the mannitol PTS operon mtl of the Vibrio cholerae El Tor biotype. The crp mutant strain was generated by homologous recombination to assess the need of CRP to activate the mannitol PTS operon of V. cholerae El Tor. Electrophoretic mobility shift assays (EMSA) and the reporter plasmid pBBRlux were used to confirm the role that the CRP-cAMP complex playing on the mannitol PTS operon mtl. In this study, we confirmed that CRP is strictly needed for the activation of the mtl operon. We further experimentally identified five CRP binding sites within the promoter region upstream of the mannitol PTS operon mtl of the Vibrio cholerae El Tor biotype and found that these sites display different affinities for CRP and provide different contributions to the activation of the operon. The five binding sites collectively confer the strong activation of mannitol transfer by CRP in V. cholerae, indicating an elaborate and subtle CRP activation mechanism.

    In this study, the effects of concentrations 0, 100, 250, 500, 750 and 1000 mg kg"−"1 of nanoscale zero-valent iron (nZVI) on germination, seedlings growth, physiology and toxicity mechanisms were investigated. The results showed that nZVI had no effect on germination, but inhibited the rice seedlings growth in higher concentrations (>500 mg kg"−"1 nZVI). The highest suppression rate of the length of roots and shoots reached 46.9% and 57.5%, respectively. The 1000mg kg"−"1 nZVI caused the highest suppression rates for chlorophyll and carotenoids, at 91.6% and 85.2%, respectively. In addition, the activity of antioxidant enzymes was altered by the translocation of nanoparticles and changes in active iron content. Visible symptoms of iron deficiency were observed at higher concentrations, at which the active iron content decreased 61.02% in the shoots, but the active iron content not decreased in roots. Interestingly, the total and available amounts of iron in the soil were not less than those in the control. Therefore, the plants iron deficiency was not caused by (i) deficiency of available iron in the soil and (ii) restraint of the absorption that plant takes in the available iron, while induced by (ⅲ) the transport of active iron from the root to the shoot was blocked. The cortex tissues were seriously damaged by nZVI which was transported from soil to the root, these were proved by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS). This current study shows that the mechanism of iron deficiency in rice seedling was due to transport of active iron from the root to the shoot blocked, which was caused by the uptake of nZVI. - Highlights: • Higher concentrations of nZVI induced iron deficiency in rice seedlings visibly. • nZVI was taken in rice seedlings and transported form root to shoot. • The pathway of active iron transport from root to shoot was inhibited. • The cortex tissues

    Full Text Available Background: Whatever its etiology, the inflammatory reactions of preeclampsia lead to the activation of endothelium and result in vascular damage. CRP is considered a sensitive index of systemic inflammation, so it is used as predictive factor for disease. This study was carried out to test the screening and predictive abilities of the CRP test in order to detect and diagnose pregnant women prone to preeclampsia prior to the onset of symptoms.Methods: In this prospective cohort study, conducted in Arash Hospital between 2005 and 2006, we determined the CRP levels of 201 pregnant women at 10-16 weeks of pregnancy. Based on exclusion criteria and illness, 31 patients were excluded and 170 patients were followed until the end of their pregnancies.Results: In this study, the mean serum CRP values of those who had preeclamptic and those who had normal pregnancies were compared and the statistical differences were significant: 6.18 mg/L for preeclamptic patients compared with 4.12 mg/L for normal patients (p=0.003. Using a chi-square test, we found that patients whose CRP level was ≥4 were six times more likely to have preeclampsia than those with CRP levels <4 (k=9.4; p=0.002; OR=6.15; 95% CI=0.69-22.28.Conclusion: This study confirms the results of previous reports indicating a significant relationship between rising serum CRP in the first trimester of pregnancy and preeclampsia at third trimester. More studies consisting of other inflammation factors are necessary to find an acceptable and reasonable screening test to diagnose pregnant women who are prone to preeclampsia.

    Biodiesel is produced by transesterification of fatty acid methyl esters (FAME) from oleaginous microalgae feedstock. Biodiesel fuel properties were studied and compared with biodiesel standards. Qualitative analysis of FAME was done while cultivating mixed microalgae consortia under three concentrations of coal fired flue gas (1%, 3.0% and 5.5% CO 2 ). Under 1% CO 2 concentration (flue gas), the FAME content was 280.3 μg/mL, whereas the lipid content was 14.03 μg/mL/D (day). Both FAMEs and lipid contents were low at other CO 2 concentrations (3.0 and 5.5%). However, mixed consortia in the presence of phosphate buffer and flue gas (PB + FG) showed higher saturated fatty acids (SFA) (36.28%) and unsaturated fatty acids (UFA) (63.72%) versus 5.5% CO 2 concentration, which might be responsible for oxidative stability of biodiesel. Subsequently, higher cetane number (52) and low iodine value (136.3 gI 2 /100 g) biodiesel produced from mixed consortia (PB + FG) under 5.5% CO 2 along with 50 mM phosphate buffer were found in accordance with European (EN 14214) standard. Results revealed that phosphate buffer significantly enhanced the biodiesel quality, but reduced the FAME yield. This study intended to develop an integrated approach for significant improvement in biodiesel quality under surplus phosphorus by utilizing waste flue gas (as CO 2 source) using microalgae. The CO 2 sequestration from industrial flue gas not only reduced greenhouse gases, but may also ensure the sustainable and eco-benign production of biodiesel. Copyright © 2018.

    Chronic low-grade inflammation is involved in the initiation and progression of atherosclerosis and ischemic heart disease. This was rare in pre-western Inuit who lived on a diet that consisted mainly of marine mammals rich in n-3 fatty acids. To assess the association between biomarkers of inflammation and the intake of traditional Inuit diet in addition to Inuit ethnicity. YKL-40 and hsCRP were measured in serum from 535 Inuit and non-Inuit living in the capital city Nuuk in West Greenland or in the main town or a settlement in rural East Greenland. Dietary habits were assessed by an interview-based food frequency questionnaire. The participation rate was 95%. YKL-40 was higher in Inuit than in non-Inuit (p Inuit with a higher intake of traditional Inuit diet (p Inuit from rural compared to urban areas (p Inuit had higher hsCRP compared to non-Inuit (p = 0.003) and hsCRP increased in parallel with intake of traditional Inuit foods (p Inuit (p = 0.004). YKL-40 and hsCRP increased with higher intakes of traditional Inuit diet after adjusting for ethnicity, gender, age, smoking, alcohol intake and BMI. Biomarkers of inflammation vary in parallel with the intake of traditional Inuit diet. A diet based on marine mammals from the Arctic does not reduce inflammatory activity and it may be speculated that markers of inflammation reflect the disease rather than the cause of the disease.

    A well-based, reactive barrier system using controlled-release potassium permanganate (CRP system) was recently developed as a long-term treatment option for dilute plumes of chlorinated solvents in groundwater. In this study, we performed large-scale (L x W x D = 8 m x 4 m x 2 m) flow-tank experiments to examine remedial efficacy of the CRP system. A total of 110 CRP rods (OD x L=5 cm x 150 cm) were used to construct a well-based CRP system (L x W x D = 3 m x 4 m x 1.5 m) comprising three discrete barriers installed at 1-m interval downstream. Natural sands having oxidant demand of 3.7 g MnO(4)(-)kg(-1) for 500 mg L(-1)MnO(4)(-) were used as porous media. After MnO(4)(-) concentrations were somewhat stabilized (0.5-6.0 mg L(-1)), trichloroethylene (TCE) plume was flowed through the flow-tank for 53 d by supplying 1.19 m(3)d(-1) of TCE solution. Mean initial TCE concentrations were 87 microg L(-1) for first 20 d and 172 microg L(-1) for the next 33 d. During TCE treatment, flow velocity (0.60md(-1)), pH (7.0-8.2), and concentrations of dissolved metals ([Al]=0.7 mg L(-1), [Fe]=0.01 mg L(-1)) showed little variations. The MnO(2)(s) contents in the sandy media measured after the TCE treatment ranged from 21 to 26 mg kg(-1), slightly increased from mean baseline value of 17 mg kg(-1). Strengths of the TCE plume considerably diminished by the CRP system. For the 87 microg L(-1) plume, TCE concentrations decreased by 38% (53), 67% (29), and 74% (23 microg L(-1)) after 1st, 2nd, and 3rd barriers, respectively. For the 172 microg L(-1) plume, TCE concentrations decreased by 27% (125), 46% (93), and 65% (61 microg L(-1)) after 1st, 2nd, and 3rd barriers, respectively. Incomplete destruction of TCE plume was attributed to the lack of lateral dispersion in the unpumped well-based barrier system. Development of delivery systems that can facilitate lateral spreading and mixing of permanganate with contaminant plume is warranted.

    C-reactive protein (CRP) is a risk marker for type 2 diabetes mellitus and cardiovascular diseases. In polycystic ovary syndrome (PCOS), limited data are available on high-sensitivity C-reactive protein (hs-CRP) levels and its relationship with components of PCOS especially in Indian women. The objective was to determine serum hs-CRP concentration in adolescent women with and without PCOS and to assess possible correlations of serum hs-CRP levels with components of PCOS in Indian women. One hundred and sixty women with PCOS and sixty non-PCOS women having normal menstrual cycles were included. Clinical assessment included anthropometry, Ferriman-Gallwey (FG) score and blood pressure (BP) measurement. Laboratory evaluation included estimation of T4, TSH, LH, FSH, total testosterone, prolactin, cortisol, 17OHP, hs-CRP, lipid profile, and insulin, and glucose after 2-h oral glucose tolerance test. Homeostasis Model Assessment Insulin resistance index (HOMA-IR) and Quantitative Insulin Sensitivity Check Index (QUICKI) and glucose intolerance was calculated. FG score, LH, FSH, total Testosterone, HOMA-IR and QUICKI were significantly different among women with or without PCOS (p women having PCOS, there was no significant difference between the groups (p > 0.05). A significant and positive correlation was found between hs-CRP and body mass index (BMI) (r = 0.308, p Indian adolescent women suggest that hs-CRP levels may not per se be associated with PCOS, rather can be related to fat mass in this subset of subjects.

    Maturity-onset diabetes of the young (MODY) as a result of mutations in hepatocyte nuclear factor 1-α (HNF1A) is often misdiagnosed as type 1 diabetes or type 2 diabetes. Recent work has shown that high-sensitivity C-reactive protein (hs-CRP) levels are lower in HNF1A-MODY than type 1 diabetes, type 2 diabetes, or glucokinase (GCK)-MODY. We aim to replicate these findings in larger numbers and other MODY subtypes. hs-CRP levels were assessed in 750 patients (220 HNF1A, 245 GCK, 54 HNF4-α [HNF4A], 21 HNF1-β (HNF1B), 53 type 1 diabetes, and 157 type 2 diabetes). hs-CRP was lower in HNF1A-MODY (median [IQR] 0.3 [0.1-0.6] mg/L) than type 2 diabetes (1.40 [0.60-3.45] mg/L; P MODY (1.45 [0.46-2.88] mg/L; P MODY (0.60 [0.30-1.80] mg/L; P MODY (0.60 [0.10-2.8] mg/L; P = 0.07). hs-CRP discriminated HNF1A-MODY from type 2 diabetes with hs-CRP MODY than other forms of diabetes and may be used as a biomarker to select patients for diagnostic HNF1A genetic testing.

    In December 2005, the International Atomic Energy Agency (IAEA) has started a Coordinated Research Project (CRP) on 'Analytical and Experimental Benchmark Analyses of Accelerator Driven Systems'. The overall objective of the CRP, performed within the framework of the Technical Working Group on Fast Reactors (TWGFR) of IAEA's Nuclear Energy Department, is to increase the capability of interested Member States in developing and applying advanced reactor technologies in the area of long-lived radioactive waste utilization and transmutation. The specific objective of the CRP is to improve the present understanding of the coupling of an external neutron source (e.g. spallation source) with a multiplicative sub-critical core. The participants are performing computational and experimental benchmark analyses using integrated calculation schemes and simulation methods. The CRP aims at integrating some of the planned experimental demonstration projects of the coupling between a sub-critical core and an external neutron source (e.g. YALINA Booster in Belarus, and Kyoto University's Critical Assembly (KUCA)). The objective of these experimental programs is to validate computational methods, obtain high energy nuclear data, characterize the performance of sub-critical assemblies driven by external sources, and to develop and improve techniques for sub-criticality monitoring. The paper summarizes preliminary results obtained to-date for some of the CRP benchmarks. (authors)

    We have developed a modified SELEX (systematic evolution of ligands by exponential enrichment) method to obtain RNA aptamers with high affinity to C-reactive protein (CRP). CRP is a clinical biomarker present in plasma, the level of which increases in response to infections and noninfectious inflammation. The CRP level is also an important prognostic indicator in patients with several syndromes. At present, CRP content in blood is measured immunochemically using antibodies. To develop a more sensitive method using RNA aptamers, we have attempted to obtain high-affinity RNA aptamers to CRP. We succeeded in obtaining an RNA aptamer with high affinity to CRP using a CRP-immobilized Sepharose column and pre-elution procedure. Pre-elution is a method that removes the weak binding portion from a selected RNA population by washing for a short time with buffer containing CRP. By surface plasmon-resonance (SPR) analysis, the affinity constant of this aptamer for CRP was calculated to be K D = 2.25x10 -9 (M). The secondary structure, contact sites with CRP protein, and application of this aptamer will be described.

    Schizophrenia is a devastating psychiatric disorder that impacts on social functioning and quality of life, and there is accumulating evidence that inflammation is a potential pathogenic mechanism of schizophrenia. However, the mechanism of inflammation possibly occurred in schizophrenia has not been well understood. The endogenous retroviral protein syncytin-1 and inflammatory marker CRP are both abnormally expressed in schizophrenia patients. CRP is one of the markers of bacterial infection generally. Less clear is whether virus or viral protein can trigger the activation of CRP. Here, we detected a robust increase of the levels of syncytin-1 and CRP in schizophrenia patients, and displayed a positive correlation and marked consistency between expressions of syncytin-1 and CRP in schizophrenia patients. Furthermore, overexpression of syncytin-1 significantly elevated the levels of CRP, TLR3, and IL-6 in both human microglia and astrocytes. TLR3 deficiency impaired the expressions of CRP and IL-6 induced by syncytin-1. Importantly, we observed a cellular co-localization and a direct interaction between syncytin-1 and TLR3. Additionally, knockdown of IL-6 inhibited the syncytin-1-induced CRP expression. Thus, the totality of these results showed that viral protein syncytin-1 could trigger the activation of CRP, which might explain the elevated CRP in sterile inflammation and exhibit a novel mechanism for regulation of inflammation by syncytin-1 in schizophrenia.

    Full Text Available Background: The presence of C-reactive protein (CRP during different stages of stroke had been shown in several studies. There is still no definite document about the correlation of CRP level and size of infarct in stroke. We studied the correlation of the acute level of CRP with size of infarct in stroke. Methods: A total of 90 consecutive patients with acute stroke admitted in Fatemeh Zahra University Hospital in Bushehr city were studied. Levels of CRP were measured at admission time and 48 hours later. Sizes of infarct and types of stroke were determined with Computerized Tomography scanning. The excluded patients were those with infection, stroke in brain stem, a delay more than 24 hours after attack of stroke and Transient Ischemic Attacks. CRP level was measured quantitatively using ELISA method. Results: No correlation between the first CRP levels and variables of age, size of infarct and type of stroke was detected. Size of infarct was correlated with the second CRP (r=0.41, P<0.001 and the difference in CRP levels (r=0.45, P<0.001. The CRP difference was significant in ischemic, hemorrhagic and territory infarcts (P<0.01. But there was no difference between the first and the second CRP in lacunar infarcts. Conclusion: We found no correlation between the CRP levels of the 24 first hours after acute stroke with size of infarct in stroke. But the increase of CRP levels which were measured in 48 hours after the stroke had correlation with size of infarct irrespective of types of stroke. More studies could reveal the cause and effect of CRP in size of infarct in stroke.

    Regardless of different sources, methods or devices which are applied for preparation of therapeutic platelets, these products are generally isolated from whole blood by the sedimentation techniques which are based on PRP or buffy coat (BC) separation. As a general fact, platelet preparation and storage are also associated with some deleterious changes that known as platelet storage lesion (PSL). Although these alternations in platelet functional activity are aggravated during storage, whether technical issues within preparation can affect integrin activation and platelet adhesion to fibrinogen were investigated in this study. PRP- and BC-platelet concentrates (PCs) were subjected to flowcytometry analysis to examine the expression of platelet activation marker, P-selectin as well as active confirmation of the GPIIb/IIIa (α IIb β 3 ) on day 0, 1, 3 and 5 post-storage. Platelet adhesion to fibrinogen matrix was evaluated by fluorescence microscopy. Glucose concentration and LDH activity were also measured by colorimetric methods. The increasing P-selectin expression during storage was in a reverse correlation with PAC-1 binding (r = -0.67; p = .001). PRP-PCs showed the higher level of P-selectin expression than BC-PCs, whereas the levels of PAC-1 binding and platelet adhesion to fibrinogen matrix were significantly lower in PRP-PCs. Higher levels of active confirmation of the GPIIb/IIIa in BC-PCs were also associated with greater concentration of glucose in these products. We demonstrated the superior capacities of integrin activation and adhesion to fibrinogen for BC-PCs compared to those of PRP-PCs. These findings may provide more advantages for BC method of platelet preparation. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The physiological role of C-reactive protein (CRP), the classical acute-phase protein, is not well documented, despite many reports on biological effects of CRP in vitro and in model systems in vivo. It has been suggested that CRP protects mice against lethal toxicity of bacterial infections by implementing immunological responses. In Achatina fulica CRP is a constitutive multifunctional protein in haemolymph and considered responsible for their survival in the environment for millions of years. The efficacy of Achatina CRP (ACRP) was tested against both Salmonella typhimurium and Bacillus subtilis infections in mice where endogenous CRP level is negligible even after inflammatory stimulus. Further, growth curves of the bacteria revealed that ACRP (50 microg/mL) is bacteriostatic against gram negative salmonellae and bactericidal against gram positive bacilli. ACRP induced energy crises in bacterial cells, inhibited key carbohydrate metabolic enzymes such as phosphofructokinase in glycolysis, isocitrate dehydrogenase in TCA cycle, isocitrate lyase in glyoxylate cycle and fructose-1,6-bisphosphatase in gluconeogenesis. ACRP disturbed the homeostasis of cellular redox potential as well as reduced glutathione status, which is accompanied by an enhanced rate of lipid peroxidation. Annexin V-Cy3/CFDA dual staining clearly showed ACRP induced apoptosis-like death in bacterial cell population. Moreover, immunoblot analyses also indicated apoptosis-like death in ACRP treated bacterial cells, where activation of poly (ADP-ribose) polymerase-1 (PARP) and caspase-3 was noteworthy. It is concluded that metabolic impairment by ACRP in bacterial cells is primarily due to generation of reactive oxygen species and ACRP induced anti-bacterial effect is mediated by metabolic impairment leading to apoptosis-like death in bacterial cells.

    At the initial Coordinated Research Project (CRP) planning meeting held in August 2011, international experts in spent fuel performance confirmed the value of further coordination and development of international efforts to demonstrate the performance of spent fuel and related storage system components as durations extend. Furthermore, in recognition that the Extended Storage Collaboration Program (ESCP) managed by the Electric Power Research Institute (EPRI) in the USA, from now on ESCP, provided a broad context for the research and development work to be performed in the frame of this CRP, it was agreed that its objectives should target specific ESCP needs in order to make a relevant contribution. Accordingly, the experts examined on-going gap analyses - gaps between anticipated technical needs and existing technical data - for identify the specific research objectives. Additionally, during the planning meeting it was pointed out the need to coordinate and cooperate with the OECD/NEA counterparts involved in the organization of the International Workshop planned in autumn 2013 and with the on-going third phase of the CRP on Spent Fuel Performance Assessment and Research (SPAR-III). Given the importance to assess the performance of spent fuel and related important storage system components in order to confirm the viability of very long term storage for supporting the need to extend or renew licenses for storage facilities the CRP was approved by the IAEA in November 2011. While a full range of spent fuel types and storage conditions are deployed around the world, this CRP is focused on existing systems and, more specifically, water reactor fuel in dry storage with the overall research objective to support the technical basis for water reactor spent fuel management as dry storage durations extend. In March 2012 the group of international experts who participated at the initial CRP planning meeting in August 2011 evaluated and recommended for approval 9 research

    Full Text Available Abstract Background The fish oil-derived ω-3 fatty acids, like docosahexanoic (DHA, claim a plethora of health benefits. We currently evaluated the antitumor effects of DHA, alone or in combination with cisplatin (CP in the EAC solid tumor mice model, and monitored concomitant changes in serum levels of C-reactive protein (CRP, lipid peroxidation (measured as malondialdehyde; MDA and leukocytic count (LC. Further, we verified the capacity of DHA to ameliorate the lethal, CP-induced nephrotoxicity in rats and the molecular mechanisms involved therein. Results EAC-bearing mice exhibited markedly elevated LC (2-fold, CRP (11-fold and MDA levels (2.7-fold. DHA (125, 250 mg/kg elicited significant, dose-dependent reductions in tumor size (38%, 79%; respectively, as well as in LC, CRP and MDA levels. These effects for CP were appreciably lower than those of DHA (250 mg/kg. Interestingly, DHA (125 mg/kg markedly enhanced the chemopreventive effects of CP and boosted its ability to reduce serum CRP and MDA levels. Correlation studies revealed a high degree of positive association between tumor growth and each of CRP (r = 0.85 and leukocytosis (r = 0.89, thus attesting to a diagnostic/prognostic role for CRP. On the other hand, a single CP dose (10 mg/kg induced nephrotoxicity in rats that was evidenced by proteinuria, deterioration of glomerular filtration rate (GFR, -4-fold, a rise in serum creatinine/urea levels (2–5-fold after 4 days, and globally-induced animal fatalities after 7 days. Kidney-homogenates from CP-treated rats displayed significantly elevated MDA- and TNF-α-, but reduced GSH-, levels.

    In this study, calcium and phosphorous ions in the simulated body fluid (SBF) was be increased to increase the rate of precipitation of hydroxyapatite (HA). The soaking temperature in concentrated calcium and phosphorous ion-SBF (CP-SBF) was increased to reduce the nucleation energy of the HA, which lead to an early precipitation to shorten the treatment process. When the metallic substrates treated with 10 M NaOH aqueous solution and subsequently heated at 600 deg. C, a thin sodium titanium oxide layer was formed on the surfaces as the linking layer for HA and Ti-6Al-4V alloys. After Ti-6Al-4V alloys treated with alkali solution, it would soak into a simulated body fluid with higher concentration of calcium and phosphorous ions (CP-SBF) to increase the possibility of nucleation of HA. When Ti-6Al-4V alloys treated with alkali solution, subsequently heated at 600 deg. C, and then soaked into CP-SBF at a temperature of 80 deg. C, it could form a dense and thick (50 μm) bone-like hydroxyapatite layer on the surface. The HA layer was appeared on the surface of the Ti-alloy at the first week soaking, which was greatly shorten the coating process. In the research, the characteristics of the coating layer will be analyzed by the results of X-ray diffractometer (XRD), scanning electron microscope (SEM), and Fourier transformation infrared (FT-IR)

    A carbonyl reductase (cr) gene from Candida glabrata CBS138 has been heterologously expressed in cofactor regenerating E. coli host to convert Ethyl-4-chloro-3-oxobutanoate (COBE) into Ethyl-4-chloro-3-hydroxybutanoate (CHBE). The CR enzyme exhibited marked velocity at substrate concentration as high as 363mM with highest turnover number (112.77±3.95s -1 ). Solitary recombineering of such catalytic cell reproduced CHBE 161.04g/L per g of dry cell weight (DCW). Introduction of combinatorially engineered crp (crp*, F136I) into this heterologous E. coli host yielded CHBE 477.54g/L/gDCW. Furthermore, using nerolidol as exogenous cell transporter, the CHBE productivity has been towered to 710.88g/L/gDCW. The CHBE production has thus been upscaled to 8-12 times than those reported so far. qRT-PCR studies revealed that both membrane efflux channels such as acrAB as well as ROS scavenger genes such as ahpCF have been activated by engineering crp. Moreover, membrane protecting genes such as manXYZ together with solvent extrusion associated genes such as glpC have been upregulated inside mutant host. Although numerous proteins have been investigated to convert COBE to CHBE; this is the first approach to use engineering triad involving crp engineering, recombinant DNA engineering and transporter engineering together for improving cell performance during two-phase biocatalysis.

    Full Text Available This study sought to explore the degree of orexin levels in Chinese opiate and methamphetamine addicts and the differences between them. The cross-sectional study was conducted among detoxified drug addicts from Mandatory Detoxification Center (MDC in five Chinese cities. Orexin levels were assayed with radioimmunoassay (RIA. Mann-Whitney U test and Kruskal-Wallis test were used to detect differences across groups, and logistic regression was used to explore the association between orexin levels and characteristics of demographic and drug abuse. Between November 2009 and January 2011, 285 opiates addicts, 112 methamphetamine addicts, and 79 healthy controls were enrolled. At drug withdrawal period, both opiate and methamphetamine addicts had lower median orexin levels than controls, and median orexin levels in opiate addicts were higher than those in methamphetamine addicts (all above P<0.05. Adjusted odds of the above median concentration of orexin were higher for injection than “chasing the dragon” (AOR = 3.1, 95% CI = 1.2–7.9. No significant factors associated with orexin levels of methamphetamine addicts were found. Development of intervention method on orexin system by different administration routes especially for injected opiate addicts at detoxification phase may be significant and was welcome.

    2014-12-01

    Full Text Available Aim: This study was intended to assess the clinical usefulness of blood procalcitonin (PCT concentrations for the diagnosis and therapeutic monitoring of nosocomial neonatal sepsis.Material/Methods: The enrolment criterion was sepsis clinically manifesting after three days of life. PCT concentrations were measured in venous blood from 52 infected and 88 uninfected neonates. The results were interpreted against C-reactive protein (CRP concentrations and white blood cell counts (WBC.Results: Differences between the two groups in PCT and CRP concentrations were highly significant. No significant differences between the groups were noted for WBC. The threshold value on the receiver operator characteristic curve was 2.06 ng/mL for PCT (SE 75%; SP 80.68%; PPV 62.22%; NPV 88.75%; AUC 0.805, 5.0 mg/L for CRP (SE 67.44%; SP 73.68%; PPV 42.02%; NPV 88.89%; AUC 0.801, and 11.9 x109/L for WBC (SE 51.16%; SP 50.68%; PPV 23.16%; NPV 78.13%; AUC 0.484. Procalcitonin concentrations decreased 24 hours after initiation of antibiotic therapy and reverted to the control level after 5-7 days. C-reactive protein concentrations began to decline after two days of antibiotic therapy but were still higher than in the control group after 5-7 days of treatment. No significant changes in WBC during the treatment were observed.Conclusions: Procalcitonin concentrations in blood appear to be of use for the diagnosis and therapeutic monitoring of nosocomial infections in neonates as this parameter demonstrates greater sensitivity and specificity than C-reactive protein. White blood cell counts appear to be of little diagnostic value in the early phase of infection or for therapeutic monitoring.

    Two major transcriptional regulators of carbon metabolism in bacteria are Cra and CRP. CRP is considered to be the main mediator of catabolite repression. Unlike for CRP, in vivo DNA binding information of Cra is scarce. Here we generate and integrate ChIP-exo and RNA-seq data to identify 39 binding sites for Cra and 97 regulon genes that are regulated by Cra in Escherichia coli. An integrated metabolic-regulatory network was formed by including experimentally-derived regulatory information and a genome-scale metabolic network reconstruction. Applying analysis methods of systems biology to this integrated network showed that Cra enables optimal bacterial growth on poor carbon sources by redirecting and repressing glycolysis flux, by activating the glyoxylate shunt pathway, and by activating the respiratory pathway. In these regulatory mechanisms, the overriding regulatory activity of Cra over CRP is fundamental. Thus, elucidation of interacting transcriptional regulation of core carbon metabolism in bacteria by two key transcription factors was possible by combining genome-wide experimental measurement and simulation with a genome-scale metabolic model.

  15. Multi-Marker Strategy in Heart Failure: Combination of ST2 and CRP Predicts Poor Outcome.

    Full Text Available Natriuretic peptides (BNP and NT-proBNP are recognized as gold-standard predictive markers in Heart Failure (HF. However, currently ST2 (member of the interleukin 1 receptor family has emerged as marker of inflammation, fibrosis and cardiac stress. We evaluated ST2 and CRP as prognostic markers in 178 patients with chronic heart failure in comparison with other classical markers such as clinical established parameters but also biological markers: NT-proBNP, hs-cTnT alone or in combination. In multivariate analysis, subsequent addition of ST2 led to age, CRP and ST2 as the only remaining predictors of all-cause mortality (HR 1.03, HR 1.61 and HR 2.75, respectively as well as of cardiovascular mortality (HR 1.00, HR 2.27 and HR 3.78, respectively. The combined increase of ST2 and CRP was significant for predicting worsened outcomes leading to identify a high risk subgroup that individual assessment of either marker. The same analysis was performed with ST2 in combination with Barcelona score. Overall, our findings extend previous data demonstrating that ST2 in combination with CRP as a valuable tool for identifying patients at risk of death.

    Over 13 million ha of former cropland are enrolled in the US Conservation Reserve Program (CRP), providing well-recognized biodiversity, water quality, and carbon (C) sequestration benefits that could be lost on conversion back to agricultural production. Here we provide measurements of the greenhouse gas consequences of converting CRP land to continuous corn, corn-soybean, or perennial grass for biofuel production. No-till soybeans preceded the annual crops and created an initial carbon debt of 10.6 Mg CO(2) equivalents (CO(2)e)·ha(-1) that included agronomic inputs, changes in C stocks, altered N(2)O and CH(4) fluxes, and foregone C sequestration less a fossil fuel offset credit. Total debt, which includes future debt created by additional changes in soil C stocks and the loss of substantial future soil C sequestration, can be constrained to 68 Mg CO(2)e·ha(-1) if subsequent crops are under permanent no-till management. If tilled, however, total debt triples to 222 Mg CO(2)e·ha(-1) on account of further soil C loss. Projected C debt repayment periods under no-till management range from 29 to 40 y for corn-soybean and continuous corn, respectively. Under conventional tillage repayment periods are three times longer, from 89 to 123 y, respectively. Alternatively, the direct use of existing CRP grasslands for cellulosic feedstock production would avoid C debt entirely and provide modest climate change mitigation immediately. Incentives for permanent no till and especially permission to harvest CRP biomass for cellulosic biofuel would help to blunt the climate impact of future CRP conversion.

  17. A mutant crp allele that differentially activates the operons of the fuc regulon in Escherichia coli.

    Zhu, Y; Lin, E C

    1988-05-01

    L-Fucose is used by Escherichia coli through an inducible pathway mediated by a fucP-encoded permease, a fucI-encoded isomerase, a fucK-encoded kinase, and a fucA-encoded aldolase. The adolase catalyzes the formation of dihydroxyacetone phosphate and L-lactaldehyde. Anaerobically, lactaldehyde is converted by a fucO-encoded oxidoreductase to L-1,2-propanediol, which is excreted. The fuc genes belong to a regulon comprising four linked operons: fucO, fucA, fucPIK, and fucR. The positive regulator encoded by fucR responds to fuculose 1-phosphate as the effector. Mutants serially selected for aerobic growth on propanediol became constitutive in fucO and fucA [fucO(Con) fucA(Con)], but noninducible in fucPIK [fucPIK(Non)]. An external suppressor mutation that restored growth on fucose caused constitutive expression of fucPIK. Results from this study indicate that this suppressor mutation occurred in crp, which encodes the cyclic AMP-binding (or receptor) protein. When the suppressor allele (crp-201) was transduced into wild-type strains, the recipient became fucose negative and fucose sensitive (with glycerol as the carbon and energy source) because of impaired expression of fucA. The fucPIK operon became hyperinducible. The growth rate on maltose was significantly reduced, but growth on L-rhamnose, D-galactose, L-arabinose, glycerol, or glycerol 3-phosphate was close to normal. Lysogenization of fuc+ crp-201 cells by a lambda bacteriophage bearing crp+ restored normal growth ability on fucose. In contrast, lysogenization of [fucO(Con)fucA(Con)fucPIK(Non)crp-201] cells by the same phage retarded their growth on fucose.

    Full Text Available Introduction: Both inflammation and mitochondrial DNA (mtDNA mutation are thought to play a role in the many human cancers. The aim of this study was to evaluate the relationship between inflammation and accumulation of mitochondrial DNA (mtDNA mutations in the D-loop region in carcinogenesis of gastro-oesophageal adenocarcinomas. Materials and Methods: Blood samples of 20 patients with gastro-oesophageal adenocarcinoma were taken for measurement of serum C-reactive protein (CRP concentration. Direct sequencing of mtDNA in the D-loop region was done in the 20 adenocarcinoma samples and their corresponding surrounding non-cancerous tissue. Sequences were compared with existing mtDNA databases to identify mutations. Results: mtDNA mutations in the D-loop region occur commonly with almost identical frequency in both non-cancerous tissue (3.0 ΁ 1.6 and adenocarcinoma (3.1 ΁ 1.9 (P = 0.916, paired t-test. CRP levels are not predictive of the number of D-loop mutations in both adenocarcinoma (β: -0.131; 95% CI: -2.354-1.364; P = 0.583 and non-cancerous tissue samples (β: 0.130; 95% CI: -1.125-1.933; P = 0.586. Five new mutations were identified that were not recorded previously in mtDNA databases. Conclusion: D-loop mtDNA mutations are common in both gastro-oesophageal adenocarcinoma and surrounding non-cancerous tissue. However, the accumulation of such mutations appears to occur independent of systemic inflammation. The frequency of D-loop mutations is likely not useful as a marker for carcinogenesis in gastro-oesophageal adenocarcinoma.

    Wastewater with high ammonia concentration is produced by many industries. However, the removal of higher loaded industrial effluents still poses many questions. Dynamic modelling is helpful to understand the process of nitrification and to investigate algorithms of process control. Therefore, a dynamic model of nitrification in completely mixed reactors is proposed based on mass balances for the components ammonia, nitrite, nitrate, dissolved oxygen, carbon dioxide, pH, nitrosomonas and nitrobacter. The biological reaction rates consider oxygen limitation and substrate inhibition. The process model presented it tested by lab scale experiments using an aerated stirred tank reactor. (orig.) [Deutsch] Es wird ein mathematisches Prozessmodell fuer die Nitrifikation von Industrieabwaessern mit hoher Ammoniumkonzentration vorgestellt, das bislang vernachlaessigte Phaenomene wie z.B. Substratueberschusshemmung und Sauerstofflimitierung beruecksichtigt. Als theoretische Grundlage dienen Bilanzgleichungen fuer insgesamt acht Komponenten. Das Simulationsmodell wird durch den Vergleich mit experimentellen Ergebnissen aus einer Laborversuchsanlage auf seine Richtigkeit ueberprueft. In dem Beitrag werden auf diesem Modell basierende Anwendungsbeispiele behandelt. So werden die Moeglichkeiten der dynamischen Prozesssimulation zur Steigerung der Betriebsstabilitaet bei schwankenden Zulaufkonzentrationen und -volumenstroemen gezeigt. Darueber hinaus gelingt die Rekonstruktion der Umsatzraten r(O{sub 2}) und r(NH{sub 3}) aus der Sauerstoff- und Kohlendioxidkonzentration in der Abluft. (orig.)

    We show a new system named AZCATL-CRP to design full power control rod patterns in BWRs. Azcatl-CRP uses an ant colony system and a reactor core simulator for this purpose. Transition and equilibrium cycles of Laguna Verde Nuclear Power Plant (LVNPP) reactor core in Mexico were used to test Azcatl-CRP. LVNPP has 109 control rods grouped in four sequences and currently uses control cell core (CCC) strategy in its fuel reload design. With CCC method only one sequence is employed for reactivity control at full power operation. Several operation scenarios are considered, including core water flow variation throughout the cycle, target different axial power distributions and Haling conditions. Azcatl-CRP designs control rod patterns (CRP) taking into account safety aspects such as k {sub eff} core value and thermal limits. Axial power distributions are also adjusted to a predetermined power shape.

    Measurements of protein-conjugated acrolein (PC-Acro), IL-6, and C-reactive protein (CRP) in plasma were useful for identifying silent brain infarction with high sensitivity and specificity. The aim of this study was to determine whether acrolein causes increased production of IL-6 and CRP in thrombosis model mice and cultured cells. In mice with photochemically induced thrombosis, acrolein produced at the locus of infarction increased the level of IL-6 and then CRP in plasma. This was confirmed in cell culture systems - acrolein stimulated the production of IL-6 in mouse neuroblastoma Neuro-2a cells, mouse macrophage-like J774.1 cells, and human umbilical vein endothelial cells (HUVEC), and IL-6 in turn stimulated the production of CRP in human hepatocarcinoma cells. The level of IL-6 mRNA was increased by acrolein through an increase in phosphorylation of the transcription factors, c-Jun, and NF-κB p65. Furthermore, CRP stimulated IL-6 production in mouse macrophage-like J774.1 cells and HUVEC. IL-6 functioned as a protective factor against acrolein toxicity in Neuro-2a cells and HUVEC. These results show that acrolein stimulates the synthesis of IL-6 and CRP, which function as protecting factors against acrolein toxicity, and that the combined measurement of PC-Acro, IL-6, and CRP is effective for identification of silent brain infarction. The combined measurements of protein-conjugated acrolein (PC-Acro), IL-6, and C-reactive protein (CRP) in plasma were useful for identifying silent brain infarction. The aim of this study was to determine whether acrolein causes increased production of IL-6 and CRP, and indeed acrolein increased IL-6 synthesis and IL-6 in turn increased CRP synthesis. Furthermore, IL-6 decreased acrolein toxicity in several cell lines. © 2013 International Society for Neurochemistry.

    Objective: To investigate the significance of changes of serum IL-6, TNF-α, hs-CRP levels in development of coronary heart disease in patients with type 2 diabetes mellitus. Methods: Serum IL-6, TNF-α (with RIA). hs-CRP (with CLIA) and FPG, TG, cholesterol (with biochemistry) contents were measured in (1) DM2 patients complicated with CHD, n=40 and (2) DlVI2 patients without CHD, n=48. Results: The BMI and FPG, TG levels were significantly higher in patients complicated with heart disease than those in patients without CHD (P<0.05) with the exception of cholesterol. The levels of IL-6, TNF-α and hs-CRP were also significantly higher in patients with heart disease than those in patients without heart disease (P<0.05). Conclusion: The high levels of IL-6, TNF-α and hs-CRP played important role in the development of coronary heart disease. Monitoring those levels might be helpful in assessment of treatment efficacy and outcome prediction. (authors)

    Liver diseases are many and vary widely in etiology and pathology. Pattern of liver diseases also vary depending on the geographical and demographical factors. Alcoholic cirrhosis is more common in industrialised countries whereas post necrotic or post hepatitic cirrhosis is more common in developing countries. Abscesses and parasitic cysts are more common in less privileged countries whereas cancer seems to be equally prevalent in all parts of the world. These differences in geographic pathology of liver diseases influence the education, training, learning process and skills of medical personnel who interpret liver images obtained from various imaging modalities. Thus the skills of liver image interpretation becomes an important variable which determines the ultimate value of a given imaging modality. In different countries, the training of nuclear medicine physicians vary in scope and content. The coordinated research programme (CRP), ''Evaluation of imaging procedures in the diagnosis of liver diseases (Phase II)'' endeavoured to address all these aspects mentioned above. This CRP was started in 1989 as a logical sequence to its predecessor, ''Evaluation of nuclear medicine procedures for the diagnosis of liver diseases''. Apart from Japan, nine other countries participated in the CRP. The objective of the CRP was to determine the sensitivity and specificity of the radiocolloid liver imaging and the standard grey scale ultrasound imaging of liver in different types of liver diseases with a view to determine the relative merit of each imaging modality in the diagnosis of a given type of liver disease. The intention was that if one shows distinctive superiority in term of its diagnostic value, then that modality can be recommended as a front line investigation in a given type of liver disease. This approach not only gives certain cost effectiveness in patient care, but also reduces demand on resources that are already under strain in developing countries

    Growth of E. coli on several carbon sources is dependent on the catabolite repressor/activator (Cra) protein although a Cra consensus DNA-binding site is not present in the control regions of the relevant catabolic operons. We show that Cra regulates growth by activating expression of the crp gene. It thereby mediates catabolite repression of catabolic operons by an indirect mechanism. © 2014 S. Karger AG, Basel.

This study was carried out to assess the correlation between progranulin, granulin, adiponectin and visceral adipose tissue-derived serine protease inhibitor (Vaspin with metaflammation (high sensitivity C-reactive protein (hs-CRP in centrally obese men. METHODS: This study was observational with a cross sectional design involving 60 men aged 30-60 years, consisted of 43 obese men (waist circumference (WC ≥90 cm and 13 non obese men (WC 105 cm. CONCLUSIONS: We found metaflammation (hs-CRP was significantly correlated with Vaspin, but not with progranulin, granulin and adiponectin, in obese men. We suggest the possibility of a dynamic expression of adipokines related to WC that are subjected to adipocytes hypertrophy-hyperplasia phenomenon. KEYWORDS: progranulin, granulin, adiponectin, Vaspin, hs-CRP, metaflammation, central obesity.

    Secreted cysteine-rich peptides (CRPs) represent one of the main classes of signalling peptides in plants. Whereas post-translationally modified small non-CRP peptides (psNCRPs) are mostly involved in signalling events during vegetative development and interactions with the environment, CRPs are overrepresented in reproductive processes including pollen germination and growth, self-incompatibility, gamete activation and fusion as well as seed development. In this opinion paper we compare the involvement of both types of peptides in vegetative and reproductive phases of the plant lifecycle. Besides their conserved cysteine pattern defining structural features, CRPs exhibit hypervariable primary sequences and a rapid evolution rate. As a result, CRPs represent a pool of highly polymorphic signalling peptides involved in species-specific functions during reproduction and thus likely represent key players to trigger speciation in plants by supporting reproductive isolation. In contrast, precursers of psNCRPs are proteolytically processed into small functional domains with high sequence conservation and act in more general processes. We discuss parallels in downstream processes of CRP signalling in both reproduction and defence against pathogenic fungi and alien pollen tubes, with special emphasis on the role of ROS and ion channels. In conclusion we suggest that CRP signalling during reproduction in plants has evolved from ancient defence mechanisms. © The Author 2016.

    Full Text Available The objective of the present study was to investigate the association of hs-CRP levels with environmental risk factors of diabetic nephropathy like smoking, drinking alcohol, diet, age of diabetic patient, duration of diabetes, medication of diabetes, and blood pressure medication. A hospital-based quantitative study was conducted at the Department of Clinical Biochemistry of Manipal Teaching Hospital (MTH Pokhara, Nepal, with 89 patients suffering from type 2 diabetes. Blood samples (n=89 from the patients were collected and the serums were separated. On the other hand, data on environmental risk factors of nephropathy were collected by using standard questionnaire. In this study, serum hs-CRP level was not found to be correlated with smoking (p=0.111, alcohol consumption (p=0.722, diet (p=0.496, duration of diabetes (p=0.519, age of diabetic patient (p=0.369, medication of diabetes (p=0.734, and blood pressure medication (p=0.625. Hence, our study concludes that serum hs-CRP value in type 2 diabetic patients is insignificantly correlated with the risk factors especially smoking, drinking alcohol, diet, duration of diabetes, age of diabetic patient, medication of diabetes, and medication of blood pressure.

    A novel centrosome-related protein Crp F46 was detected using a serum F46 from a patient suffering from progressive systemic sclerosis. We identified the protein by immunoprecipitation and Western blotting followed by tandem mass spectrometry sequencing. The protein Crp F46 has an apparent molecular mass of ∼ 60 kDa, is highly homologous to a 527 amino acid sequence of the C-terminal portion of the protein Golgin-245, and appears to be a splice variant of Golgin-245. Immunofluorescence microscopy of synchronized HeLa cells labeled with an anti-Crp F46 monoclonal antibody revealed that Crp F46 localized exclusively to the centrosome during interphase, although it dispersed throughout the cytoplasm at the onset of mitosis. Domain analysis using Crp F46 fragments in GFP-expression vectors transformed into HeLa cells revealed that centrosomal targeting is conferred by a C-terminal coiled-coil domain. Antisense Crp F46 knockdown inhibited cell growth and proliferation and the cell cycle typically stalled at S phase. The knockdown also resulted in the formation of poly-centrosomal and multinucleate cells, which finally became apoptotic. These results suggest that Crp F46 is a novel centrosome-related protein that associates with the centrosome in a cell cycle-dependent manner and is involved in the progression of the cell cycle and M phase mechanism

    Members of the cysteine-rich protein (CRP) family are actin cytoskeleton-interacting LIM-domain proteins known to act in muscle cell differentiation. We have earlier found that CRP1, a founding member of this family, is transcriptionally induced by UV radiation in human diploid fibroblasts [M. Gentile, L. Latonen, M. Laiho, Cell cycle arrest and apoptosis provoked by UV radiation-induced DNA damage are transcriptionally highly divergent responses, Nucleic Acids Res. 31 (2003) 4779-4790]. Here we show that CRP1 is induced by growth-inhibitory signals, such as increased cellular density, and cytotoxic stress induced by UV radiation or staurosporine. We found that high levels of CRP1 correlate with differentiation-associated morphology towards the myofibroblast lineage and that expression of ectopic CRP1 suppresses cell proliferation. Following UV- and staurosporine-induced stresses, expression of CRP1 provides a survival advantage evidenced by decreased cellular death and increased cellular metabolic activity and attachment. Our studies identify that CRP1 is a novel stress response factor, and provide evidence for its growth-inhibitory and cytoprotective functions

    2016-11-01

    Full Text Available Several pretransplant factors, including CRP (C-reactive protein levels, reflect the risk of complications after allogeneic stem cell transplantation. IL-6 induces CRP increase, and we therefore investigated the effects of pretransplant IL-6, soluble IL-6 receptors, IL-6 family cytokines and CRP serum levels on outcome for 100 consecutive allotransplant recipients. All patients had related donors, none had active infections and 99 patients were in complete remission before conditioning. The incidence of acute graft versus host disease (aGVHD requiring treatment was 40%, survival at Day +100 82%, and overall survival 48%. Despite a significant correlation between pretransplant CRP and IL-6 levels, only CRP levels significantly influenced transplant-related mortality (TRM. However, CRP did not influence overall survival (OS. Pretransplant IL-31 influenced late TRM. Finally, there was a significant association between pretransplant IL-6 and early postconditioning weight gain (i.e., fluid retention, and this fluid retention was a risk factor for aGVHD, TRM and OS. To conclude, pretransplant CRP, IL-31 and early posttransplant fluid retention were independent risk factors for TRM and survival after allotransplantation.

    Feasibility study for a cellulosic ethanol plant using grasses grown on Conservation Reserve Program lands in three counties of South Dakota, with several subcomponent appendices. In 1994, there were over 1.8 million acres of CRP lands in South Dakota. This represented approximately 5 percent of the total U.S. cropland enrolled in the CRP. Nearly 200,000 acres of CRP lands were concentrated in three northeastern South Dakota counties: Brown, Marshall and Day. Most of the acreage was planted in Brohm Grass and Western Switchgrass. Technology under development at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL), and at other institutions, is directed towards the economical production of fuel-grade ethanol from these grasses. The objective of this study is to identify and evaluate a site in northeastern South Dakota which would have the greatest potential for long-term operation of a financially attractive biomass-to-ethanol production facility. The effort shall focus on ethanol marketing issues which would provide for long-term viability of the facility, feedstock production and delivery systems (and possible alternatives), and preliminary engineering considerations for the facility, as well as developing financial pro-formas for a proposed biomass-to-ethanol production facility in northeastern South Dakota. This Final Report summarizes what was learned in the tasks of this project, pulling out the most important aspects of each of the tasks done as part of this study. For greater detail on each area it is advised that the reader refer to the entire reports which are included as appendixes.

    This report contains the actual status of the Belgian contribution to the IAEA CRP-IV program. Besides Charpy-V impact tests on as-received CRP-IV JRQ-specimens, fracture toughness tests were performed on two geometries: PCCV-specimens and CRB-specimens. The Charpy-V impact results correspond very well with the as-received CRP-III results. The fracture toughness data are also very consistent with identical tests recently performed on remaining as-received CRP-III material. Irradiated broken Charpy-V samples were reconstituted and tested in PCCV-mode. This was done in order to investigate the evolution of the ASME-curve versus the evolution of the mastercurve with irradiation. Initial results were reported. A new CHIVAS-irradiation in the CALLISTO-loop of the BR-2-reactor to support this investigation, is under preparation

    Serum C reactive protein (CRP) has been shown to be associated with the progression of esophageal cancer. The purpose of this study was to examine the relationship between treatment response and serum CRP levels in time course during definitive chemoradiotherapy (CRT) in terms of early prediction of CRT response by serum CRP. The subjects of this study were 36 patients with cT3/cT4 esophageal squamous cell carcinoma who underwent definitive CRT in our hospital. Serum CRP levels during definitive CRT (pretreatment, 1W, 2W and 3W after CRT initiation) were compared between CR and non-CR group. In addition, partition model was constructed to discriminate CR with non-CR and the prediction accuracy was evaluated. The patients were consisted of 28 males and 8 females. At pretreatment diagnosis, tumors were categorized as T3 (n=21) and T4 (n=15). Thirty four patients received FP-based chemotherapy and 2 patients received docetaxel-based chemotherapy. Treatment responses were categorized as CR (n=8), partial response (PR) (n=14), no change (NC) (n=2) and progressive disease (PD) (n=12). Serum CRP levels at the time of 2W after CRT initiation (CRT2W) in CR group were low compared to those in non-CR group (p=0.071). The partition model was constructed based on CRP levels at CRT2W. The prediction accuracies to discriminate CR from non-CR by CRP ≤0.1 were 50%, 82%, and 75% in sensitivity, specificity and accuracy, respectively. Serum CRP is a useful biomarker for an early prediction of CRT response. (author)

    Filtering out the noise in traffic collision data is essential in reducing false positive rates (i.e., requiring safety investigation of sites where it is not needed) and can assist government agencies in better allocating limited resources. Previous studies have demonstrated that denoising traffic collision data is possible when there exists a true known high collision concentration location (HCCL) list to calibrate the parameters of a denoising method. However, such a list is often not readily available in practice. To this end, the present study introduces an innovative approach for denoising traffic collision data using the Ensemble Empirical Mode Decomposition (EEMD) method which is widely used for analyzing nonlinear and nonstationary data. The present study describes how to transform the traffic collision data before the data can be decomposed using the EEMD method to obtain set of Intrinsic Mode Functions (IMFs) and residue. The attributes of the IMFs were then carefully examined to denoise the data and to construct Continuous Risk Profiles (CRPs). The findings from comparing the resulting CRP profiles with CRPs in which the noise was filtered out with two different empirically calibrated weighted moving window lengths are also documented, and the results and recommendations for future research are discussed.

    Full Text Available Postoperative complications frequently follow major abdominal surgery and are associated with increased morbidity and mortality. Early diagnosis and treatment of complications is associated with improved patient outcome. In this study we assessed the value of a step-up diagnosis plan by C-reactive protein and CT-scan (computed tomography-scan imaging for detection of postoperative complications following major abdominal surgery. An observational cohort study was conducted of 399 consecutive patients undergoing major abdominal surgery between January 2009 and January 2011. Indication for operation, type of surgery, postoperative morbidity, complications according to the Clavien-Dindo classification and mortality were recorded. Clinical parameters were recorded until 14 days postoperatively or until discharge. Regular C-reactive protein (CPR measurements in peripheral blood and on indication -enhanced CT-scans were performed. Eighty-three out of 399 (20.6 % patients developed a major complication in the postoperative course after a median of seven days (IQR 4-9 days. One hundred and thirty two patients received additional examination consisting of enhanced CT-scan imaging, and treatment by surgical reintervention or intensive care observation. CRP levels were significantly higher in patients with postoperative complications. On the second postoperative day CRP levels were on average 197.4 mg/L in the uncomplicated group, 220.9 mg/L in patients with a minor complication and 280.1 mg/L in patients with major complications (p < 0,001. CT-scan imaging showed a sensitivity of 91.7 % and specificity of 100 % in diagnosis of major complications. Based on clinical deterioration and the increase of CRP, an additional enhanced CT-scan offered clear discrimination between patients with major abdominal complications and uncomplicated patients. Adequate treatment could then be accomplished.

    Full Text Available Samples of freshly fallen snow were collected at the high alpine research station Jungfraujoch (Switzerland in February and March 2006 and 2007, during the Cloud and Aerosol Characterization Experiments (CLACE 5 and 6. In this study a new technique has been developed and demonstrated for the measurement of organic acids in fresh snow. The melted snow samples were subjected to solid phase extraction and resulting solutions analysed for organic acids by HPLC-MS-TOF using negative electrospray ionization. A series of linear dicarboxylic acids from C5 to C13 and phthalic acid, were identified and quantified. In several samples the biogenic acid pinonic acid was also observed. In fresh snow the median concentration of the most abundant acid, adipic acid, was 0.69 μg L−1 in 2006 and 0.70 μg L−1 in 2007. Glutaric acid was the second most abundant dicarboxylic acid found with median values of 0.46 μg L−1 in 2006 and 0.61 μg L−1 in 2007, while the aromatic acid phthalic acid showed a median concentration of 0.34 μg L−1 in 2006 and 0.45 μg L−1 in 2007. The concentrations in the samples from various snowfall events varied significantly, and were found to be dependent on the back trajectory of the air mass arriving at Jungfraujoch. Air masses of marine origin showed the lowest concentrations of acids whereas the highest concentrations were measured when the air mass was strongly influenced by boundary layer air.

    Low iron (Fe) stores may influence absorption or transport of divalent metals in blood. To obtain more knowledge about such associations, the divalent metal ions cadmium (Cd), manganese (Mn), cobalt (Co), copper (Cu), zinc (Zn) and lead (Pb) and parameters of Fe metabolism (serum ferritin, haemoglobin (Hb) and transferrin) were investigated in 448 healthy, menstruating non-smoking women, age 20-55 years (mean 38 years), participating in the Norwegian HUNT 2 study. The study population was stratified for serum ferritin: 257 were iron-depleted (serum ferritin <12 {mu}g/L) and 84 had iron deficiency anaemia (serum ferritin <12 {mu}g/L and Hb<120 g/L). The low ferritin group had increased blood concentrations of Mn, Co and Cd but normal concentrations of Cu, Zn and Pb. In multiple regression models, ferritin emerged as the main determinant of Mn, Co and Cd (p<0.001), while no significant associations with Cu, Zn and Pb were found. Adjusted r{sup 2} for the models were 0.28, 0.48 and 0.34, respectively. Strong positive associations between blood concentrations of Mn, Co and Cd were observed, also when controlled for their common association with ferritin. Apart from these associations, the models showed no significant interactions between the six divalent metals studied. Very mild anaemia (110{<=}Hb<120 g/L) did not seem to have any effect independent of low ferritin. Approximately 26% of the women with iron deficiency anaemia had high concentrations of all of Mn, Co and Cd as opposed to 2.3% of iron-replete subjects. The results confirm that low serum ferritin may have an impact on body kinetics of certain divalent metal ions, but not all. Only a fraction of women with low iron status exhibited an increased blood concentration of divalent metals, providing indication of complexities in the body's handling of these metals.

    Airborne contaminants produced by industrial agricultural facilities contain chemical and biological compounds that can impact the health of residents living in close proximity. Settled dust can be a reservoir for these contaminants and can influence long-term exposures. In this study, we sampled the indoor- and outdoor-settled dust from 40 homes that varied in proximity to industrial-scale dairies (ISD; industrial-scale dairy, a term used in this paper to describe a large dairy farm and adjacent waste sprayfields, concentrated animal feeding operation or animal feeding operation, that uses industrial processes) in the Yakima Valley, Washington. We analyzed settled dust samples for cow allergen (Bos d2, a cow allergen associated with dander, hair, sweat and urine, it is a member of the lipocalin family of allergens associated with mammals), mouse allergen (Mus m1; major mouse allergen, a mouse urinary allergen, in the lipocalin family), dust mite allergens (Der p1 (Dermatophagoides pteronissinus 1) and Der f1 (Dermatophagoides farinae 1)), and endotoxin (a component of the cell walls of gram negative bacteria, lipopolysaccharide, which can be found in air and dust and can produce a strong inflammatory response). A concentration gradient was observed for Bos d2 and endotoxin measured in outdoor-settled dust samples based on proximity to ISD. Indoor-settled dust concentrations of Bos d2 and endotoxin were also highest in proximal homes. While the associated health effects of exposure to cow allergen in settled dust is unknown, endotoxin at concentrations observed in these proximal homes (100 EU/mg) has been associated with increased negative respiratory health effects. These findings document that biological contaminants emitted from ISDs are elevated in indoor- and outdoor-settled dust samples at homes close to these facilities and extend to as much as three miles (4.8 km) away.

  8. Activation of PKA in cell requires higher concentration of cAMP than in vitro: implications for compartmentalization of cAMP signalling.

    cAMP is a ubiquitous second messenger responsible for the cellular effects of multiple hormones and neurotransmitters via activation of its main effector, protein kinase A (PKA). Multiple studies have shown that the basal concentration of cAMP in several cell types is about 1 μM. This value is well above the reported concentration of cAMP required to half-maximally activate PKA, which measures in the 100-300 nM range. Several hypotheses have been suggested to explain this apparent discrepancy including inaccurate measurements of intracellular free cAMP, inaccurate measurement of the apparent activation constant of PKA or shielding of PKA from bulk cytosolic cAMP via localization of the enzyme to microdomains with lower basal cAMP concentration. However, direct experimental evidence in support of any of these models is limited and a firm conclusion is missing. In this study we use multiple FRET-based reporters for the detection of cAMP and PKA activity in intact cells and we establish that the sensitivity of PKA to cAMP is almost twenty times lower when measured in cell than when measured in vitro. Our findings have important implications for the understanding of compartmentalized cAMP signalling.

    Full Text Available Aim. Determine the metabolic profile and identify risk factors of women transitioning from gestational diabetes mellitus (GDM to type 2 diabetes mellitus (T2DM. Methods. 237 women diagnosed with GDM underwent an oral glucose tolerance test (OGTT, anthropometrics assessment, and completed lifestyle questionnaires six years after pregnancy. Blood was analysed for clinical variables (e.g., insulin, glucose, HbA1c, adiponectin, leptin, and lipid levels and NMR metabolomics. Based on the OGTT, women were divided into three groups: normal glucose tolerance (NGT, impaired glucose tolerance (IGT, and T2DM. Results. Six years after GDM, 19% of subjects had T2DM and 19% IGT. After BMI adjustment, the IGT group had lower HDL, higher leptin, and higher free fatty acid (FFA levels, and the T2DM group higher triglyceride, FFA, and C-reactive protein levels than the NGT group. IGT and T2DM groups reported lower physical activity. NMR measurements revealed that levels of branched-chain amino acids (BCAAs and the valine metabolite 3-hydroxyisobyturate were higher in T2DM and IGT groups and correlated with measures of insulin resistance and lipid metabolism. Conclusion. In addition to well-known clinical risk factors, BCAAs and 3-hydroxyisobyturate are potential markers to be evaluated as predictors of metabolic risk after pregnancy complicated by GDM.

    Earlier fieldwork in rural areas of Hainan Island, China, demonstrated that during the course of economic development increasing differences had emerged in lifestyles within communities. It is possible that these variations might have stratified residents into subpopulations with different health attributes. This study examined the association between C-reactive protein (CRP) concentration, a biomarker of future cardiovascular events, and personal lifestyle parameters and the degree of community-level economic development among rural communities. A cross-sectional field survey was undertaken in 19 rural communities in Hainan. Convenience sampling was used to recruit 1,744 participants. Dried blood spot samples were collected to measure high-sensitivity CRP concentration. Sex-stratified multilevel regression analyses were conducted to identify factors associated with CRP concentration among the participants. While CRP concentration was negatively associated with being married and (more) education among men, for women CRP concentration was associated with the frequency of poultry consumption (P = 0.014) and the experience of migratory work in the previous year (P = 0.009). In addition, for females, living in communities with a greater degree of inequality, as indexed by the Gini coefficient, was also associated with increased CRP concentration (P = 0.003). Given that CRP concentration is a marker of future CVD risk, this study suggests that within these previously homogenous rural communities, economic development might have stratified people into population subgroups with a different CVD risk. © 2015 Wiley Periodicals, Inc.

    Although cardiac rehabilitation is known as a tool to reduce the overall risk of cardiovascular complications, its specific role in the reduction of hs-CRP as a marker of inflammation and a proven marker of cardiovascular risk needs further investigation. The present study aims at elucidating the effects of a full course of conventional cardiac rehabilitation program for the period of eight weeks, on the levels of hs-CRP in patients who underwent isolated coronary artery bypass surgery. In this case study, 30 consecutive patients who underwent isolated coronary artery bypass surgery (isolated CABGS), and a full 8-week cardiac rehabilitation program in Tehran Heart Center, were investigated. A group of 30 similar patients, who enrolled in the same period of rehabilitation program but did not participate in practice, was considered as a control group. Serum levels of hs-CRP in both groups were measured retrospectively and in similar days before the start of rehabilitation program and at the end of it (or 8 weeks after initial registration for the control group). Levels of hs-CRP in the rehabilitation group and control group were 5.9 7.7 and 6.3 6.9 respectively before start of the program which was not statistically meaningful ( P -Value = 0.833). However, after the program, level of hs-CRP in the two tested groups changed to 2.3 5.1 and 5.7 6.1 respectively which showed a meaningful correlation ( P -Value = 0.023). These results also showed that decrease in hs-CRP level in the rehabilitated group but not in the control group was statistically meaningful (with P -Value of 0.037 and 0.0723 respectively). In patients undergoing coronary bypass surgery, participating in a full course of cardiac rehabilitation for 8 weeks has resulted in a significant reduction in hs-CRP levels as a marker of cardiovascular risk.

    Objective: To investigate the β-cell function status and possible mechanism of insulin resistance in patients with type 2 diabetes through studies on the changes of serum APN, insulin, CRP, leptin, insulin antibody and glutamic acid decarboxylase antibody (GAD-Ab) levels after one year of treatment. Methods: Serum levels of the above four parameters and the positive rate of the two antibodies were measured (with CLIA, ELISA and RIA as appropriately) in 184 patients with type 2 diabetes and 30 controls as well as in 75 patients after one year of treatment. Results: The serum contents of insulin, leptin, CRP, insulin antibody in patients with type 2 diabetes were significantly higher (P<0.01) and APN levels significantly lower (P<0.001) than those in controls. Levels of APN were negatively correlated with those of the other parameters. In the 75 treated patients, levels of those parameters (with the exception of APN and insulin-antibody) decreased significantly. However, the APN levels were significantly increased (vs before treatment, P<0.001). Conclusion: Further study on the dynamic changes of these parameters in the diabetic patients might elucidate certain key-points in the pathogenesis of the disease. (authors)

    Full Text Available Introduction & Objective: Several studies have been performed to evaluate correlation of serum high sensitivity CRP (hs-CRP level with the prognosis of the patients with diagnosis of unstable angina, and by now different results were reported. The aim of this study was to assess correlation between serum hs-CRP level and inhospital prognosis and cardiac events in the patients with unstable angina. Materials & Methods: This descriptive analytic study was performed from Sep 2004 till Feb 2006 in Shahid Beheshti hospital. Kermanshah, Iran. Sera were collected from 250 patients for hs-CRP measurement. Exclusion criteria were: acute ST elevation MI, non ST elevation MI, patients with history of recent infection, patients with recent trauma and patients with serum high sensitive CRP level more than 10 mg/lit. Patients were divided into two groups, first group whose serum hs-CRP level was less than 3 mg/lit and second group whose serum hs-CRP level was between 3 and 10 mg/lit. They were followed for recurrent chest pain, arrhythmias, pulmonary edema, acute myocardial infarction and in hospital death. Results were analyzed using x² and t-test. Results: Mean age were 57±7.8 and 58±11.5 years in first group and second group respectively. There was statistically significant difference in some cardiac complications such as dyspnea, duration of hospitalization, recurrent chest pain, CCU admission (p<0.001 and in hospital myocardial infarction (p=0.03, between two groups. Some complications did not have significant difference such as pulmonary edema, cardiogenic shock, arrhythmia, S3, S4 and pulmonary rates .There was no mortality in both groups. Conclusion: According to the results, we can use serum hs-CRP level for risk stratification in the patients with diagnosis of unstable angina. Obviously the patients with high serum hs-CRP level need more attention whether early invasive management help these patients, may be the matter of later studies.

    The CRP/FNR family transcription factor from M. tuberculosis H37Rv has been crystallized in space group P2 1 2 1 2 1 in the absence of cAMP. The crystals show the presence of a dimeric molecule in the asymmetric unit. CRP/FNR family members are transcription factors that regulate the transcription of many genes in Escherichia coli and other organisms. Mycobacterium tuberculosis H37Rv contains a probable CRP/FNR homologue encoded by the open reading frame Rv3676. The deletion of this gene is known to cause growth defects in cell culture, in bone marrow-derived macrophages and in a mouse model of tuberculosis. The mycobacterial gene Rv3676 shares ∼32% sequence identity with prototype E. coli CRP. The structure of the protein might provide insight into transcriptional regulation in the pathogen by this protein. The M. tuberculosis CRP/FNR transcription regulator was crystallized in space group P2 1 2 1 2 1 , with unit-cell parameters a = 54.1, b = 84.6, c = 101.2 Å. The crystal diffracted to a resolution of 2.9 Å. Matthews coefficient and self-rotation function calculations reveal the presence of two monomers in the asymmetric unit

    In December 2005, the International Atomic Energy Agency (IAEA) has started a Coordinated Research Project (CRP) on 'Analytical and Experimental Benchmark Analyses of Accelerator Driven Systems'. The overall objective of the CRP, performed within the framework of the Technical Working Group on Fast Reactors (TWGFR) of IAEA's Nuclear Energy Department, is to increase the capability of interested Member States in developing and applying advanced reactor technologies in the area of long-lived radioactive waste utilization and transmutation. The specific objective of the CRP is to improve the present understanding of the coupling of an external neutron source (e.g. spallation source) with a multiplicative sub-critical core. The participants are performing computational and experimental benchmark analyses using integrated calculation schemes and simulation methods. The CRP aims at integrating some of the planned experimental demonstration projects of the coupling between a sub-critical core and an external neutron source (e.g. YALINA Booster in Belarus, and Kyoto University's Critical Assembly (KUCA)). The objective of these experimental programs is to validate computational methods, obtain high energy nuclear data, characterize the performance of sub-critical assemblies driven by external sources, and to develop and improve techniques for sub-criticality monitoring. The paper summarizes preliminary results obtained to-date for some of the CRP benchmarks. (authors)

    The systematic evolution of ligands by exponential enrichment (SELEX) is an experimental procedure that allows screening of given molecular targets by desired binding affinities from an initial random pool of oligonucleotides and oligomers. The final products of SELEX are usually referred as aptamers, which are recognized as promising molecules for a variety of biomedical applications. However, SELEX is an iterative process requiring multiple rounds of extraction and amplification that demands significant time and labor. Therefore, this study presents a novel, automatic, miniature SELEX platform. As a demonstration, the rapid screening of C-reactive protein (CRP) aptamers was performed. By utilizing microfluidic technologies and magnetic beads conjugated with CRP, aptamers with a high affinity to CRP were extracted from a random single-strand deoxyribonucleic acid (ssDNA) pool. These aptamers were further amplified by an on-chip polymerase chain reaction (PCR) process. After five consecutive extraction and amplification cycles, a specific aptamer with the highest affinity was screened automatically. The screened aptamers were used as a recognition molecule for the detection of CRP. The developed microsystem demonstrated fast screening of CRP aptamers and can be used as a powerful tool to select analyte-specific aptamers for biomedical applications. (c) 2009 Elsevier B.V.

    2016-01-01

    Full Text Available To test the statistical association of the CRP and SAA1 locus variants with their corresponding circulating levels and metabolic and inflammatory biomarker levels by using mediation analysis, a sample population of 599 Taiwanese subjects was enrolled and five CRP and four SAA1 variants were genotyped. Correlation analysis revealed that C-reactive protein (CRP and serum amyloid A (SAA levels were significantly associated with multiple metabolic phenotypes and inflammatory marker levels. Our data further revealed a significant association of CRP and SAA1 variants with both CRP and SAA levels. Mediation analysis revealed that SAA levels suppressed the association between SAA1 genotypes/haplotypes and CRP levels and that CRP levels suppressed the association between CRP haplotypes and SAA levels. In conclusion, genetic variants at the CRP and SAA1 loci independently affect both CRP and SAA levels, and their respective circulating levels act as suppressors. These results provided further evidence of the role of the suppression effect in biological science and may partially explain the missing heritability in genetic association studies.

  2. Evaluation of the results of the IAEA/FAO CRP on tropical transfer factors

    Future development of tropical countries will include nuclear power. This is particularly true following the recent attention given to the urgent need to reduce greenhouse gas emissions. From this, it is apparent that there is a need to have the ability to undertake dose assessments within tropical and sub-tropical regions. This includes knowledge of appropriate biological transfer factors for the region. However, most previous transfer factor studies were undertaken within temperate regions, predominantly in the Northern Hemisphere. Following a preliminary data survey, there was thus found to be a paucity of data for tropical and sub-tropical regions (excluding marine ecosystems). In an attempt to rectify this situation, the IAEA and FAO instigated a cooperative research program (CRP) entitled 'Transfer of radionuclides from air, soil and freshwater to the food chain of man in tropical and subtropical environments.' This paper is a synopsis of the findings of the three year CRP project. It is important to recognize that the data used in this presentation are derived from contributors and their colleagues in several countries. A list of chief investigators is given. Dr Martin Frissel, Secretary, European IUR, deserves a special mention for his collation of the CRP data. Some of his figures were used in the presentation or reproduced in this synopsis. The participants undertook regional literature and data surveys, field sampling and experimental investigations. The experimental studies were run by following, as closely as practicable, a suite of standard protocols that helped to reduce variability and errors. The experimental studies comprised two main groups: soil to plant, and: freshwater to fish. Quality assurance on analytical work was performed using intercomparison tests with standard reference materials. The reporting of data was also standardised to facilitate collation and subsequent multivariate statistical analysis. The statistical analysis of the entire

    Full Text Available BACKGROUND Metabolic Syndrome (MetS is generally characterised as a clustering of the abnormal levels of blood lipids (low HDL and high triglycerides, impaired fasting glucose, elevated blood pressure, and excess abdominal obesity. The objectives of the study areTo evaluate presence of Subclinical Hypothyroidism in the study population of the patients with metabolic syndrome. To find out relation between Subclinical Hypothyroidism and different parameters of metabolic syndrome. To evaluate whether patients of metabolic syndrome with raised hs-CRP have an increased risk of having hypothyroidism. MATERIALS AND METHODS A total of 50 adult patients who met with inclusion criteria were selected. Patients with metabolic syndrome (MetS who fulfilled the NCEP-ATP III criteria: 3 out of 5 criteria positive. Patients with liver disorders, renal disorders, congestive cardiac failure, pregnant women, patients on oral contraceptive pills, statins and other medications that alter thyroid functions (e.g. lithium, amiodarone or γ-interferon were excluded from the study. RESULTS A total of 50 patients of metabolic syndrome were enrolled. Out of which 36 were euthyroid, 3 were overt hypothyroid and 11 were subclinical hypothyroid. Out of 11 patients of subclinical hypothyroidism, 9 were female and 2 were male patients. Out of 28 females, 9 (32% were SCH while out of 22 males, 2 (9% were SCH. Out of 50 patients, 3 were overt hypothyroid. All 3 patients had BP >130/85, waist circumference was >88 cm and HDL of 130/85, HDL 150 mg/dL and fasting blood glucose of >100 mg/dL were more associated with male patients. CONCLUSION Subclinical Hypothyroidism was present in 22% of study population and more so in females having metabolic syndrome (32%. Hence, it will be worthwhile to screen female metabolic syndrome patients for thyroid function abnormality. Abnormal blood pressure, triglycerides and HDL cholesterol levels were more associated with subclinical hypothyroidism

    Necrotizing fasciitis (NF) is a rare mono-/polymicrobial skin infection that spreads to underlying tissues. NF is quickly progressing and leads to life threatening situations. Immediate surgical debridement together with i.v. antibiotic administration is required to avoid fatal outcome. Early diagnosis is often delayed due to underestimation or confusion with cellulitis. We now compared the initial clinical and laboratory presentation of NF and cellulitis in detail to assess if a typical pattern can be identified that aids timely diagnosis of NF and avoidance of fatal outcome. 138 different clinical and laboratory features of 29 NF patients were compared to those of 59 age- and gender matched patients with severe erysipelas requiring a subsequent hospitalization time of ≥10 days. Differences in clinical presentation were not obvious; however, NF patients suffered significantly more often from strong pain. NF patients exhibited dramatically elevated CRP levels (5-fold, p>0.001). The overall laboratory risk indicator for necrotizing fasciitis (LRINEC) score was significantly higher in NF patients as compared to cellulitis. However, a modification of the score (alteration of laboratory parameters, addition of clinical parameters) led to a clear improvement of the score with a higher positive predictive value without losing specificity. In summary, clinical differentiation of NF from cellulitis appears to be hard. 'Pain out of proportion' may be an early sign for NF. An improvement of the LRINEC score emphasizing only relevant laboratory and clinical findings as suggested may aid the early diagnosis of NF in the future leading to improvement of disease outcome by enabling rapid adequate therapy.

    Full Text Available BACKGROUND: Central obesity is the accumulation of visceral (intra-abdominal fat and is strongly known to be associated with insulin resistance and type 2 diabetes mellitus (T2DM. Obesity can cause adipocyte hypertrophy that results in dysregulation of adipokine expression. The abnormal function of adipocytes may play an important role in the development of a chronic low-grade proinflammatory state associated with obesity. Adiponectin, retinol binding protein (RBP-4 and fetuin-A play a role in the pathophysiology of insulin resistance. Expression of fetuin-A is increased due to fat accumulation in the liver. Elevated concentration of fetuin-A in the circulation can impair insulin signaling in muscle and liver as well as suppress adiponectin secretion, although its molecular mechanism is still unclear. The aim of this study was to identify the relationship of fetuin-A, adiponectin, RBP-4 and hsCRP with insulin resistance in obese non diabetic men. METHODS: This was an observational study with a cross-sectional design. The study subjects were 64 men with non diabetic abdominal obesity, characterized by waist circumference of 98.47±5.88 cm and fasting blood glucose of 85.75±8.36 mg/dL. RESULTS: This study showed that fetuin-A was positively correlated with HOMA-IR in obese non diabetic men with insulin resistance (r=0.128; p=0.570, although not significant. Fetuin-A was found to be correlated with adiponectin, RBP-4 and hsCRP (r=0.150; p=0.233; r=0.050; p=0.711; r=-0.04; p=0.445, although not significant. CONCLUSIONS: The concentration of fetuin-A showed a tendency to be positively correlated with HOMA-IR and with RBP-4 in obese non diabetic men, although statistically not significant. The concentration of fetuin-A showed a tendency to be negatively correlated with adiponectin and hsCRP although statistically not significant. There was no interrelationship between fetuin-A, adiponectin, RBP-4, hsCRP and HOMA-IR. Elevated concentrations of fetuin

    Quaternary ammonium compounds (QACs) are cationic surfactants used as preservatives and environmental disinfectants. Limited data are available regarding the effect of QACs in the clinical setting. We performed a prospective cohort study in 153 patients with Escherichia coli bacteraemia from February to September 2008 at University Hospital in Rennes. The minimum inhibitory concentrations (MICs) of antibiotics and QACs alkyldimethylbenzylammonium chloride (ADBAC) and didecyldimethylammonium chloride (DDAC) were determined by the agar dilution method. The capacity of biofilm production was assayed using the Crystal Violet method, and mutation frequencies by measuring the capacity of strains to generate resistance to rifampicin. Logistic regression analysis showed that one of the significant factors related to low MICs for ADBAC (≤16 mg/L) and DDAC (≤8 mg/L), was cotrimoxazole susceptibility (odds ratio: 3.72; 95% confidence interval: 1.22-11.24; P=0.02 and OR: 3.61; 95% CI: 1.56-7.56; PAntibiotic susceptibility to cotrimoxazole was strongly associated with susceptibility to amoxicillin and nalidixic acid (PE. coli isolates and antibiotic resistance.

    Background: Recent studies suggest that meat intake is associated with diabetes-related phenotypes. However, whether the associations of meat intake and glucose and insulin homeostasis are modified by genes related to glucose and insulin is unknown. Objective: We investigated the associations of meat intake and the interaction of meat with genotype on fasting glucose and insulin concentrations in Caucasians free of diabetes mellitus. Design: Fourteen studies that are part of the Cohorts for Heart and Aging Research in Genomic Epidemiology consortium participated in the analysis. Data were provided for up to 50,345 participants. Using linear regression within studies and a fixed-effects meta-analysis across studies, we examined 1) the associations of processed meat and unprocessed red meat intake with fasting glucose and insulin concentrations; and 2) the interactions of processed meat and unprocessed red meat with genetic risk score related to fasting glucose or insulin resistance on fasting glucose and insulin concentrations. Results: Processed meat was associated with higher fasting glucose, and unprocessed red meat was associated with both higher fasting glucose and fasting insulin concentrations after adjustment for potential confounders [not including body mass index (BMI)]. For every additional 50-g serving of processed meat per day, fasting glucose was 0.021 mmol/L (95% CI: 0.011, 0.030 mmol/L) higher. Every additional 100-g serving of unprocessed red meat per day was associated with a 0.037-mmol/L (95% CI: 0.023, 0.051-mmol/L) higher fasting glucose concentration and a 0.049–ln-pmol/L (95% CI: 0.035, 0.063–ln-pmol/L) higher fasting insulin concentration. After additional adjustment for BMI, observed associations were attenuated and no longer statistically significant. The association of processed meat and fasting insulin did not reach statistical significance after correction for multiple comparisons. Observed associations were not modified by genetic

As a preliminary study of UAM on HTGR, this paper covers the exercise 1 and 2 of Phase I which defines the unit cell and lattice geometry of MHTGR-350 (General Atomics). The objective of these exercises is to quantify the uncertainty of the multiplication factor induced by perturbing nuclear data as well as to analyze the specific features of HTGR such as double heterogeneity and self-shielding treatment. The uncertainty quantification of IAEA CRP HTGR UAM benchmarks were conducted using first-order AWP method in McCARD. Uncertainty of the multiplication factor was estimated only for the microscopic cross section perturbation. To reduce the computation time and memory shortage, recently implemented uncertainty analysis module in MC wielandt calculation was adjusted. The covariance data of cross section was generated by NJOY/ERRORR module with ENDF/B-VII.1. The numerical result was compared with evaluation result of DeCART/MUSAD code system developed by KAERI. IAEA CRP HTGR UAM benchmark problems were analyzed using McCARD. The numerical results were compared with Serpent for eigenvalue calculation and DeCART/MUSAD for S/U analysis. In eigenvalue calculation, inconsistencies were found in the result with ENDF/B-VII.1 cross section library and it was found to be the effect of thermal scattering data of graphite. As to S/U analysis, McCARD results matched well with DeCART/MUSAD, but showed some discrepancy in 238U capture regarding implicit uncertainty.

    IAEA-CRP-6 is a coordinated research program of IAEA on Advances in HTGR fuel technology. The CRP examines aspects of HTGR fuel technology, ranging from design and fabrication to characterization, irradiation testing, performance modeling, as well as licensing and quality control issues. The benchmark section of the program treats simple analytical cases, pyrocarbon layer behavior, single TRISO-coated fuel particle behavior, and benchmark calculations of some irradiation experiments performed and planned. There are totally seventeen benchmark cases in the program. Member countries are participating in the benchmark calculations of the CRP with their own developed fuel performance analysis computer codes. Korea is also taking part in the benchmark calculations using a fuel performance analysis code, COPA (COated PArticle), which is being developed in Korea Atomic Energy Research Institute. The study shows the calculational results of IAEACRP- 6 benchmark cases 1 through 7 which describe the structural behaviors for a single fuel particle

    BACKGROUND: Cellular uptake of vitamin B12 (B12) demands binding of the vitamin to transcobalamin (TC) and recognition of TC-B12 (holoTC) by the receptor CD320, a receptor expressed in high quantities on human placenta. We have identified a soluble form of CD320 (sCD320) in serum and here we...... gestational weeks 17-41. sCD320, holoTC, total TC and complex formation between holoTC and sCD320 were measured by in-house ELISA methods, while creatinine was measured on the automatic platform Cobas 6000. Size exclusion chromatography was performed on a Superdex 200 column. RESULTS: Median (range) of serum...... was around two fold higher than in serum. Urinary sCD320/creatinine ratio correlated with serum sCD320 and reached a peak median level of 53 (30-101) pmol/mmol creatinine (week 35). sCD320 present in serum and urine showed the same elution pattern upon size exclusion chromatography. CONCLUSION: We report...

    The overall objective of the CRP is to perform R and D tasks contributing towards the proof of practicality for long-lived waste transmutation. For a sound assessment of the transient and accident behaviour, the neutron kinetics and dynamics have to be qualified, especially as the margins for the safety relevant neutronics parameters are becoming small in a 'dedicated' transmuter. The CRP will integrate benchmarking of transient/accident simulation codes focussing on the phenomena and effects relevant to various critical and sub-critical systems under severe neutron flux changes and rearrangements. The CRP will investigate future needs both for theoretical means (data, codes) and experimental information related to the various transmutation systems. The final goals of the CRP are to (a) deepen the understanding of the dynamics of transmutation systems, e.g., the accelerator driven system, especially systems with deteriorated safety parameters, (b) qualify the available methods and specify their range of validity, and (c) formulate requirements for future theoretical developments. Should transient experiments be available, the CRP might also pursue experimental benchmarking work. In any case, based on the results, the CRP will conclude on the potential need of transient experiments and make appropriate proposals for experimental programs. The CRP will consider various transmuter and actinides incinerator concepts, from traditional to very advanced, both critical and sub-critical. No optimization will be performed, experience and good engineering judgment is used to define the design parameters of the various concepts. The generic dynamic behavior of the different systems will be assessed and inter-comparisons will be performed. The concepts are derived from those proposed by the participants in this RCM. Later additions might be considered. The studies will include static, kinetics and dynamics calculations. Influence of burnup on transient behavior will be

    Full Text Available BACKGROUND: It is unclear whether C-reactive protein (CRP is causally related to coronary heart disease (CHD. Genetic variants that are known to be associated with CRP levels can be used to provide causal inference of the effect of CRP on CHD. Our objective was to examine the association between CRP genetic variant +1444C>T (rs1130864 and CHD risk in the largest study to date of this association. METHODS AND RESULTS: We estimated the association of CRP genetic variant +1444C>T (rs1130864 with CRP levels and with CHD in five studies and then pooled these analyses (N = 18,637 participants amongst whom there were 4,610 cases. CRP was associated with potential confounding factors (socioeconomic position, physical activity, smoking and body mass whereas genotype (rs1130864 was not associated with these confounders. The pooled odds ratio of CHD per doubling of circulating CRP level after adjustment for age and sex was 1.13 (95%CI: 1.06, 1.21, and after further adjustment for confounding factors it was 1.07 (95%CI: 1.02, 1.13. Genotype (rs1130864 was associated with circulating CRP; the pooled ratio of geometric means of CRP level among individuals with the TT genotype compared to those with the CT/CC genotype was 1.21 (95%CI: 1.15, 1.28 and the pooled ratio of geometric means of CRP level per additional T allele was 1.14 (95%CI: 1.11, 1.18, with no strong evidence in either analyses of between study heterogeneity (I(2 = 0%, p>0.9 for both analyses. There was no association of genotype (rs1130864 with CHD: pooled odds ratio 1.01 (95%CI: 0.88, 1.16 comparing individuals with TT genotype to those with CT/CC genotype and 0.96 (95%CI: 0.90, 1.03 per additional T allele (I(20.6 for both meta-analyses. An instrumental variables analysis (in which the proportion of CRP levels explained by rs1130864 was related to CHD suggested that circulating CRP was not associated with CHD: the odds ratio for a doubling of CRP level was 1.04 (95%CI: 0.61, 1.80.

    Radiation processing is a very convenient tool for imparting desirable effects in materials and it has been an area of enormous interest in the last few decades. Radiation processing of synthetic and natural polymers for improving their characteristics is largely used in laboratory and industrial scale. Radiation sterilization is a well developed and established technology for many products. It is especially useful for the treatment of pharmaceuticals due to flexibility of radiation processing to be carried out at any desired temperature, sterilizability of mixed products in kits, offering simultaneous sterilization and modification of polymer based formulations. The success of radiation technology for processing of synthetic and natural polymers and treatment of pharmaceuticals has been based, to a large extent, on empirical knowledge. But now, the applications of natural polymers are being sought in knowledge-demanding areas such as pharmacy and biotechnology. Reliable analytical methods are being developed for controlling of degradation effects of radiation on polymers. Procedures and chemical formulations are being investigated enhancing or preventing degradation effects depending on the desired application of the process. The Coordinated Research Project (CRP) on the use of radiation processing for sterilization or decontamination of pharmaceuticals and pharmaceutical raw materials has been completed in 2002. The overall objective of the CRP was to coordinate the research and development programmes carried out in different countries in use of radiation processing for sterilization or decontamination of pharmaceuticals and pharmaceutic raw materials.

    Hospitalization in patients with chronic heart failure is associated with high rates of mortality and morbidity that during treatment and post-treatment. Despite the various therapies available today, mortality and re-hospitalization rates within 60 to 90 days post-hospitalization are still quite high. This period is known as the vulnerable phase. With the prognostic evaluation tools in patients with heart failure are expected to help identify high-risk individuals, then more rigorous monitoring and interventions can be undertaken. To determine whether hs-CRP have an impact on mortality within 90 days in hospitalized patients with heart failure, an observational cohort study was conducted in 39 patients with heart failure who were hospitalized due to worsening chronic heart failure. Patients were followed for up to 90 days after initial evaluation with the primary endpoint is death. Hs-CRP value >4.25 mg/L we found 70% was dead and hs-CRP value <4.25 mg/L only 6.9% was dead whereas the survival within 90 days. p:0.000.In conclusion, there were differences in hs-CRP values between in patients with heart failure who died and survival within 90 days.

    C-Reactive protein (CRP) has been associated with the macro- and microvascular effects of hypertension and diabetes mellitus. Referring to serum cortisol, it has been proposed to contribute to the pathogenesis of metabolic syndrome, and it has been demonstrated that weight loss normalizes cortisol levels and improves insulin resistance. The aims of this study were to analyze CRP and cortisol levels pre- and postoperatively in morbidly obese patients undergoing a laparoscopic sleeve gastrectomy and to correlate them with weight loss and parameters associated with cardiovascular risk. A prospective study of all the morbidly obese patients undergoing laparoscopic sleeve gastrectomy as bariatric procedure between October 2007 and May 2011 was performed. A total of 40 patients were included in the study. CRP levels decreased significantly 12 months after surgery (median reduction of 8.9 mg/l; p = 0.001). Serum cortisol levels decreased significantly 6 months after surgery (median reduction of 34.9 μg/dl; p = 0.001). CRP values reached the normal range (cortisol, a significant association was observed with the cardiovascular risk predictor (triglyceride/high-density lipoprotein cholesterol ratio) from the 6th month after surgery onward (Pearson correlation coefficient, 0.559; p = 0.008). CRP levels are increased preoperatively and in the postoperative course up to 1 year after surgery. Serum cortisol levels remain elevated until the 6th month after surgery. From this moment onward, serum cortisol is associated with the cardiovascular risk predictor reflecting the cardiovascular risk decreasement during the weight loss.

    The aim of this study was to determine the effects of synbiotic food consumption on glycemic status and serum high sensitivity C-reactive protein (hs-CRP) levels of Iranian pregnant women. This randomized placebo-controlled clinical trial was performed among 52 pregnant women, primigravida, aged 18-35 year old, in their third trimester. After a 2-wk run-in period, subjects were randomly assigned to consume either a synbiotic (n=26) or control food (n=26) for 9 weeks. The synbiotic food consisted of a probiotic Lactobacillus sporogenes (1×107 CFU), 0.04 g inulin as prebiotic with 0.38 g isomalt, 0.36 g sorbitol and 0.05 g stevia as sweetener per 1 g. Control food (the same substance without probiotic bacteria and inulin) was packed in identical 9-gram packages. Patients were asked to consume the synbiotic and control foods two times a day. Fasting blood samples were taken at baseline and after a 9-wk intervention for quantification of related factors. Consumption of a synbiotic food did not show any significant change regarding the impact of insulin actions in the synbiotic group; nonetheless, compared to the control food, it resulted in a significant decrease in serum insulin levels (-0.26 vs. 6.34 µIU/mL, P=0.014) and HOMA-IR (-0.13 vs. 1.13, P=0.033), a significant difference in HOMA-B (5.30 vs. 34.22, P=0.040) and a significant rise in QUICKI score (0.002 vs. -0.02, P=0.022). Consumption of a synbiotic food for 9 weeks by pregnant women had beneficial effects on insulin actions compared to the control food, but did not affect FPG and serum hs-CRP concentrations.

    In this report, detailed data which are necessary for the benchmark analysis of International Atomic Energy Agency (IAEA) Coordinated Research Program (CRP-3) on 'Heat Transport and Afterheat Removal for Gas-cooled Reactors under Accident Conditions' are described concerning about the configuration and sizes of the cooling panel test apparatus, experimental data and thermal properties. The test section of the test apparatus is composed of pressure vessel (max. 450degC) containing an electric heater (max. 100kW, 600degC) and cooling panels surrounding the pressure vessel. Gas pressure is varied from vacuum to 1.0MPa in the pressure vessel. Two experimental cases are selected as benchmark problems about afterheat removal of HTGR, described as follows, The experimental conditions are vacuum inside the pressure vessel and heater output 13.14kW, and helium gas pressure 0.73MPa inside the pressure vessel and heater output 28.79kW. Benchmark problems are to calculate temperature distributions on the outer surface of pressure vessel and heat transferred to the cooling panel using the experimental data. The analytical result of temperature distribution on the pressure vessel was estimated +38degC, -29degC compared with the experimental data, and analytical result of heat transferred from the surface of pressure vessel to the cooling panel was estimated max. -11.4% compared with the experimental result by using the computational code -THANPACST2- of JAERI.

    Full Text Available With the increasing importance of early type 2 diabetes (DM2 and obesity detection, it is useful to reevaluate leptin role in these conditions. Our study aimed at investigating circulating leptin concentrations in a group of patients with DM2, and at assessing in detail whether leptin concentrations correlate with selected biochemical, clinical parameters and markers of systemic inflammation in patients with DM2 and in healthy volunteers. In our work, we analysed samples and data drawn from 71 patients aged 61.4 ± 11.7 years, who have been diagnosed with type 2 diabetes, as well as from a healthy control group (HC consisting of 51 healthy subjects with a mean age of 57.8 ± 13.7 years. Therein, the concentration of leptin in the DM2 patients was significantly higher than in the HC (p < 0.01, with median value of 16.59 (IQR 8.58-33.39 ng/ml in the DM2, vs median value of 6.66 (IQR 4.52-21.40 ng/ml in the HC. In the analysis of variance, higher leptin concentrations were revealed in the DM2 group as compared to the HC, and this figure remained significant after adjusting for gender and age (p < 0.001. Moreover, it was independent of HOMA-IR (p = 0.003. However, the differences in leptin levels between the groups disappeared when additional adjustments for anthropometric parameters (BMI, waist circumference were applied (p = 0.088. Beyond the aforementioned, significant positive correlations were found in the DM 2 group between leptin level and CRP (r=0.256; p < 0.05 and IL-6 (r = 0.345; p < 0.01. Among the selected variables, only gender and BMI were included in the predictive model explaining the variability of leptin, and, in total, were responsible for 72.6% of the original variation of the studied adipocytokine. The results of this study have led to conclusion that leptin may participate in the complex pathogenesis of DM2 and be a predictor of the development of this disease. As higher concentrations of leptin coexist with obesity, and this

    Little is known about the relation of modifiable dietary factors to circulating homocysteine concentrations, particularly in young adults and non-Western populations. We investigated the hypothesis that intakes of nutrients and foods are associated with serum homocysteine concentration in a group of young Japanese women. This cross-sectional study included 1050 female Japanese dietetic students aged 18 to 22 years. Dietary intake was assessed using a validated, self-administered, comprehensive diet history questionnaire. Fasting blood samples were collected, and serum homocysteine concentrations were measured. Adjustment was made for survey year, region, municipality level, current smoking, current alcohol drinking, dietary supplement use, physical activity, body mass index, energy intake, and intakes of other nutrients or foods. After adjustment for nondietary confounding factors, intakes of all B vitamins (folate, vitamin B-6, vitamin B-12, and riboflavin) were inversely associated with homocysteine concentration. However, only vitamin B-6 remained significant after further adjustment for other B vitamins. Marine-origin n-3 polyunsaturated fatty acid intake showed an inverse association, but this was not independent of intakes of B vitamins. For foods, pulses, fish and shellfish, and vegetables were independently and inversely associated with homocysteine concentration, but these associations disappeared after adjustment for intakes of other foods. Conversely, an inverse association for dairy products and a positive association for green and oolong tea remained even after adjustment for other foods. To conclude, in a group of young Japanese women, higher intake of vitamin B-6 and dairy products and lower intake of green and oolong tea were independently associated with lower serum homocysteine concentration.

  5. Measurements of Neuronal Soma Size and Estimated Peptide Concentrations in Addition to Cell Abundance Offer a Higher Resolution of Seasonal and Reproductive Influences of GnRH-I and GnIH in European Starlings.

    Hypothalamic neuropeptides involved in vertebrate reproduction, gonadotropin releasing hormone (GnRH-I) and gonadotropin-inhibitory hormone (GnIH), can vary in the abundance of immunoreactive cells as a function of the reproductive status and nest box occupation of European starlings (Sturnus vulgaris). While using the abundance of cells as an indicator of the activity of neurohormones is informative, incorporating information on cell size (readily observed using immunohistochemistry) can offer a more detailed understanding of environmentally-mediated changes in hormonal dynamics. In this study, we tested the hypothesis that the size of cells' somas and the estimated concentration of peptides in cells immunoreactive (ir) for GnRH-I and GnIH would vary throughout the breeding season and as a function of nest-box status (resident or not). In the absence of a direct assay of protein, we estimated an index of the concentration of hypothalamic peptides via the relative optical density (i.e., the difference between the mean optical density and the optical density of background staining). In support of our hypothesis, we found that GnRH-I- and GnIH-ir soma size and peptide concentration changed both in males and females throughout the breeding season. Somas were largest and estimated peptide concentration was highest mid-season when compared with earlier in the season or to the non-breeding period. For nest-box residents, GnIH-ir soma size and peptide concentration were higher during the middle of the breeding season than earlier in the breeding season, although residence in the nest box was not related to GnRH-I-ir variables. Our results confirm that previously reported changes in cell abundance mimic changes we see in GnRH-I and GnIH-ir soma size and our proxy for peptide concentration. However, investigating changes in the soma of GnRH-I-ir cells revealed a peak in size during the middle of the breeding season, a change not evident when solely examining data on the

    To demonstrate non-inferiority of iobitridol 350 for coronary CT angiography (CTA) compared to higher iodine content contrast media regarding rate of patients evaluable for the presence of coronary artery stenoses. In this multicentre trial, 452 patients were randomized to receive iobitridol 350, iopromide 370 or iomeprol 400 and underwent coronary CTA using CT systems with 64-detector rows or more. Two core lab readers assessed 18 coronary segments per patient regarding image quality (score 0 = non diagnostic to 4 = excellent quality), vascular attenuation, signal and contrast to noise ratio (SNR, CNR). Patients were considered evaluable if no segment had a score of 0. Per-patient, the rate of fully evaluable CT scans was 92.1, 95.4 and 94.6 % for iobitridol, iopromide and iomeprol, respectively. Non-inferiority of iobitridol over the best comparator was demonstrated with a 95 % CI of the difference of [-8.8 to 2.1], with a pre-specified non-inferiority margin of -10 %. Although average attenuation increased with higher iodine concentrations, average SNR and CNR did not differ between groups. With current CT technology, iobitridol 350 mg iodine/ml is not inferior to contrast media with higher iodine concentrations in terms of image quality for coronary stenosis assessment. (orig.)

    Full Text Available Objectives. Recent investigations have suggested that upregulated levels of inflammatory biomarkers, such as chemokines, may be associated with development of many malignancies, including esophageal cancer (EC. Based on our knowledge, this study is the first to assess the serum concentration of chemokine CXCL12 and its specific receptor CXCR4 in the diagnosis of EC patients. Material and Methods. The present study included 79 subjects: 49 patients with EC and 30 healthy volunteers. The serum concentrations of CXCL12 and CXCR4 and classical tumor markers such as carcinoembryonal antigen (CEA and squamous cell cancer antigen (SCC-Ag were measured using immunoenzyme assays, while C-reactive protein (CRP levels were assessed by immunoturbidimetric method. Moreover, diagnostic criteria of all proteins tested and the survival of EC patients were assessed. Results. The serum concentrations of CXCL12 were significantly higher, while those of its receptor CXCR4 were significantly lower in EC patients compared to healthy controls. The diagnostic sensitivity, negative predictive value, and accuracy of CXCR4 were the highest among all analyzed proteins and increased for combined analysis with classical tumor markers and CRP levels. Conclusion. Our findings suggest that serum CXCR4 may improve the diagnosis of EC patients, especially in combination with classical tumor markers.

    Full Text Available Introduction: Atrial fibrillation (AF is the most prevalent cardiac arrhythmias that cardiologists and internists encounter. The goal of this article is to clarify an overview of the evidence linking inflammation to AF existence, which may highlight the effect of some pharmacological agents that have genuine potential to reduce the clinical burden of AF by modulating inflammatory pathways. Materials and Methods: In a case-control study, 50 patients with atrial fibrillation (AF with different etiologies and 50 patients with sinus rhythm and similar bases were selected. Sampling for highly sensitive c-reactive (hs-CRP was done on the patients presenting with AF to the Ghaem hospital between October 2006 and June 2007. Results: Mean age of the patients was 62 years with maximum of 90 and minimum of 36 and standard deviation of 13.80. The most frequent age group was 71-80years. Fifty-four percent of patients were male and 46% were female. Mean serum hs-CRP levels in AF patients with hypertension (HTN ,Ischemic heart disease(IHD, Valvular heart disease (VHD, HTN+IHD and hyperthyroidism were 8.10, 9.40, 8.68, 10.16 and 5.98 mg/Lit; respectively. There was significant difference between hs-CRP levels in hypertensive patients in the two groups (P=0.010. Similar results were observed in IHD patients, VHD patients and HTN+IHD patients in two groups (P=0.015, P=0.037, P=0.000. Conclusion: In addition to some risk factors like baseline cardiac diseases, aging, thyrotoxicosis, pulmonary embolism, pneumonia and cardiac surgery, there also appears to be consistent links between hs-CRP, a marker of inflammation, and the pathogenesis of AF.

    Since the last RCM held in 1996, most participants have made good progress towards the objective of measuring bone mineral density (BMD) in at least 25 subjects of both sexes in each of the 5-year age ranges between 15 and 50 years (i.e. a minimum of 350 subjects in each study group). Some participants have also collected and analysed a number of bone samples, as specified in the protocols for the CRP. One of the most important tasks within the CRP is to 'normalize' the data from different DEXA machines and study centres so as to allow a meaningful comparison of the BMD measurements between centres and study groups. To this end, a European Spine Phantom (ESP) has recently been circulating among the participating centres, who have reported their results to the Central Reference Laboratory (CRL). Central evaluation of the data has so far only been done for a few of the participating centres

    IAEA Coordinated Research Program (CRP) on 'Lifetime Prediction for the First Wall of a Fusion Machine' was started in 1989. Five participants, Joint Research Centre (JRC-Ispra), The NET team, Kernforschungszentrum Karlsruhe (KfK), Russian Research Center and Japan Atomic Energy Research Institute, contributed in this activity. The purpose of the CRP is to evaluate the thermal fatigue behavior of the first wall of a next generation fusion machine by means of numerical methods and also to contribute the design activities for ITER (International Thermonuclear Experimental Reactor). Thermal fatigue experiments of a first wall mock-up which were carried out in JRC-Ispra were selected as a first benchmark exercise model. All participants performed finite element analyses with various analytical codes to predict the lifetime of the simulated first wall. The first benchmark exercise has successfully been finished in 1992. This report summarizes a JAERI's contribution for this first benchmark exercise. (author)

    Allostery is a fundamental process by which ligand binding to a protein alters its activity at a distinct site. There is growing evidence that allosteric cooperativity can be communicated by modulation of protein dynamics without conformational change. The mechanisms, however, for communicating dynamic fluctuations between sites are debated. We provide a foundational theory for how allostery can occur as a function of low-frequency dynamics without a change in structure. We have generated coarse-grained models that describe the protein backbone motions of the CRP/FNR family transcription factors, CAP of Escherichia coli and GlxR of Corynebacterium glutamicum. The latter we demonstrate as a new exemplar for allostery without conformation change. We observe that binding the first molecule of cAMP ligand is correlated with modulation of the global normal modes and negative cooperativity for binding the second cAMP ligand without a change in mean structure. The theory makes key experimental predictions that are tested through an analysis of variant proteins by structural biology and isothermal calorimetry. Quantifying allostery as a free energy landscape revealed a protein "design space" that identified the inter- and intramolecular regulatory parameters that frame CRP/FNR family allostery. Furthermore, through analyzing CAP variants from diverse species, we demonstrate an evolutionary selection pressure to conserve residues crucial for allosteric control. This finding provides a link between the position of CRP/FNR transcription factors within the allosteric free energy landscapes and evolutionary selection pressures. Our study therefore reveals significant features of the mechanistic basis for allostery. Changes in low-frequency dynamics correlate with allosteric effects on ligand binding without the requirement for a defined spatial pathway. In addition to evolving suitable three-dimensional structures, CRP/FNR family transcription factors have been selected to

    Mycobacterium tuberculosis (Mtb) encodes two CRP/FNR family transcription factors (TF) that contribute to virulence, Cmr (Rv1675c) and CRPMt (Rv3676). Prior studies identified distinct chromosomal binding profiles for each TF despite their recognizing overlapping DNA motifs. The present study shows that Cmr binding specificity is determined by discriminator nucleotides at motif positions 4 and 13. X-ray crystallography and targeted mutational analyses identified an arginine-rich loop that expands Cmr's DNA interactions beyond the classical helix-turn-helix contacts common to all CRP/FNR family members and facilitates binding to imperfect DNA sequences. Cmr binding to DNA results in a pronounced asymmetric bending of the DNA and its high level of cooperativity is consistent with DNA-facilitated dimerization. A unique N-terminal extension inserts between the DNA binding and dimerization domains, partially occluding the site where the canonical cAMP binding pocket is found. However, an unstructured region of this N-terminus may help modulate Cmr activity in response to cellular signals. Cmr's multiple levels of DNA interaction likely enhance its ability to integrate diverse gene regulatory signals, while its novel structural features establish Cmr as an atypical CRP/FNR family member. © The Author(s) 2017.

    C-reactive protein (CRP) is a biomarker of the inflammatory response, and it shows significant prognostic value for several types of solid tumors. The prognostic significance of CRP for lymphoma has not been fully examined. We evaluated the prognostic role of baseline serum CRP levels in patients with extranodal natural killer (NK)/T-cell lymphoma (ENKTL). We retrospectively analyzed 185 patients with newly diagnosed ENKTL. The prognostic value of the serum CRP level was evaluated for the low-CRP group (CRP≤10 mg/L) versus the high-CRP group (CRP>10 mg/L). The prognostic value of the International Prognostic Index (IPI) and the Korean Prognostic Index (KPI) were evaluated and compared with the newly developed prognostic model. Patients in the high-CRP group tended to display increased adverse clinical characteristics, lower rates of complete remission (P60 years, hypoalbuminemia, and elevated lactate dehydrogenase levels were independent adverse predictors of OS. Based on these four independent predictors, we constructed a new prognostic model that identified 4 groups with varying OS: group 1, no adverse factors; group 2, 1 factor; group 3, 2 factors; and group 4, 3 or 4 factors (PKPI in distinguishing between the low- and intermediate-low-risk groups, the intermediate-low- and high-intermediate-risk groups, and the high-intermediate- and high-risk groups. Our results suggest that pretreatment serum CRP levels represent an independent predictor of clinical outcome for patients with ENKTL. The prognostic value of the new prognostic model is superior to both IPI and KPI.

    The present work is the results of JNC, Japan, for the Phase 5 of IAEA CRP benchmark problem (BFS-62-3A critical experiment). Analytical Method of JNC is based on Nuclear Data Library JENDL-3.2; Group Constant Set JFS-3-J3.2R: 70-group, ABBN-type self-shielding factor table based on JENDL-3.2; Effective Cross-section - Current-weighted multigroup transport cross-section. Cell model for the BFS as-built tube and pellets was (Case 1) Homogeneous Model based on IPPE definition; (Case 2) Homogeneous atomic density equivalent to JNC's heterogeneous calculation only to cross-check the adjusted correction factors; (Case 3) Heterogeneous model based on JNC's evaluation, One-dimensional plate-stretch model with Tone's background cross-section method (CASUP code). Basic diffusion Calculation was done in 18-groups and three-dimensional Hex-Z model (by the CITATION code), with Isotropic diffusion coefficients (Case 1 and 2), and Benoist's anisotropic diffusion coefficients (Case 3). For sodium void reactivity, the exact perturbation theory was applied both to basic calculation and correction calculations, ultra-fine energy group correction - approx. 100,000 group constants below 50 keV, and ABBN-type 175 group constants with shielding factors above 50 keV. Transport theory and mesh size correction 18-group, was used for three-dimensional Hex-Z model (the MINIHEX code based on the S4-P0 transport method, which was developed by JNC. Effective delayed Neutron fraction in the reactivity scale was fixed at 0.00623 by IPPE evaluation. Analytical Results of criticality values and sodium void reactivity coefficient obtained by JNC are presented. JNC made a cross-check of the homogeneous model and the adjusted correction factors submitted by IPPE, and confirmed they are consistent. JNC standard system showed quite satisfactory analytical results for the criticality and the sodium void reactivity of BFS-62-3A experiment. JNC calculated the cross-section sensitivity coefficients of BFS

    Full Text Available Background: Coronary Artery Disease (CAD is caused by atherosclerosis. Studies have shown that a number of factors, including cellular binding molecules such as Plasminogen Activator Inhibitor-1 (PAI-1, lipid peroxidation, inflammation, and hemostasis, are closely related to development and progression of CAD. Objectives: The present case-control study aimed to evaluate the association between Plasminogen Activator Inhibitor-1 (PAI-1 4G/5G polymorphism and oxidative stress markers and Coronary Artery Disease (CAD. Patients and Methods: Blood was drawn and DNA was extracted from 90 subjects (46 patients with angiographically diagnosed CAD and 44 age- and sex-matched healthy controls. The 4G/5G polymorphism of PAI-1 was detected by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP analysis. Besides, the risk factors, serpin E1, Malondialdehyde (MDA, high-sensitivity C-Reactive Protein (hs-CRP, and lipid profile serum levels were measured by standard methods and were compared between the two study groups using independent samples t-test, one-way ANOVA, and Mann-Whitney U test as appropriated. Results: Results: The frequency of 4G/4G genotype of PAI-1 gene was higher in the CAD patients than in the controls (28/46 (60.87% vs. 8/44 (18.18%, P < 0.01. Additionally, the serpin E1 plasma level was significantly higher in the CAD group carrying the 4G allele compared to those homozygous for the 5G allele (P = 0.016. Besides, a significant difference was found between the 4G/4G and 5G/5G subjects of the CAD group regarding plasma High-Density Lipoprotein (HDL (P < 0.01. Also, significant differences were observed among the three genotypes of both groups concerning the plasma levels of cholesterol, triglyceride, and Low-Density Lipoprotein (LDL. However, no significant correlation was found between PAI-1 gene polymorphism and MDA serum level, hs-CRP, and risk of CAD. Conclusion: The findings of this study suggested that 4G/4G PAI

    Full Text Available C-reactive protein (CRP, a blood inflammatory biomarker, is associated with the development of Alzheimer disease. In animal models of Parkinson disease (PD, systemic inflammatory stimuli can promote neuroinflammation and accelerate dopaminergic neurodegeneration. However, the association between long-term systemic inflammations and neurodegeneration has not been assessed in PD patients.To investigate the longitudinal effects of baseline CRP concentrations on motor prognosis in PD.Retrospective analysis of 375 patients (mean age, 69.3 years; mean PD duration, 6.6 years. Plasma concentrations of high-sensitivity CRP were measured in the absence of infections, and the Unified Parkinson's Disease Rating Scale Part III (UPDRS-III scores were measured at five follow-up intervals (Days 1-90, 91-270, 271-450, 451-630, and 631-900.Change of UPDRS-III scores from baseline to each of the five follow-up periods.Change in UPDRS-III scores was significantly greater in PD patients with CRP concentrations ≥0.7 mg/L than in those with CRP concentrations <0.7 mg/L, as determined by a generalized estimation equation model (P = 0.021 for the entire follow-up period and by a generalized regression model (P = 0.030 for the last follow-up interval (Days 631-900. The regression coefficients of baseline CRP for the two periods were 1.41 (95% confidence interval [CI] 0.21-2.61 and 2.62 (95% CI 0.25-4.98, respectively, after adjusting for sex, age, baseline UPDRS-III score, dementia, and incremental L-dopa equivalent dose.Baseline plasma CRP levels were associated with motor deterioration and predicted motor prognosis in patients with PD. These associations were independent of sex, age, PD severity, dementia, and anti-Parkinsonian agents, suggesting that subclinical systemic inflammations could accelerate neurodegeneration in PD.

    Full Text Available Angiopoietin-like protein 2 (ANGPTL2, which is mainly expressed from adipose tissue, is demonstrated to be involved in obesity, metabolic syndrome, and atherosclerosis. Because several adipocytokines are known to be associated with heart failure (HF, here we investigated the association of ANGPTL2 and HF in Taiwanese subjects.A total of 170 symptomatic HF patients and 130 age- and sex-matched controls were enrolled from clinic. The echocardiography was analyzed in each patient, and stress myocardial perfusion study was performed for clinical suspicion of coronary artery disease. Detailed demographic information, medications, and biochemical data were recorded. Circulating adipocytokines, including tumor necrosis factor-alpha (TNF-α, adiponectin, adipocyte fatty acid-binding protein (A-FABP and ANGPTL2, were analyzed. Compared with the control group subjects, serum ANGPTL2 concentrations were significantly higher in HF group patients. In correlation analyses, ANGPTL2 level was positively correlated to creatinine, fasting glucose, triglyceride, hsCRP, TNF-α, NT-proBNP and A-FABP levels, and negatively correlated with HDL-C and left ventricular ejection fraction. In multiple regression analysis, A-FABP, hsCRP, and HDL-C levels remained as independent predictors for ANGPTL2 level. To determine the association between serum ANGPTL2 concentrations and HF, multivariate logistic regression analyses were performed with subjects divided into tertiles by ANGPTL2 levels. For the subjects with ANGPTL2 levels in the highest tertile, their risk of HF was about 2.97 fold (95% CI = 1.24-7.08, P = 0.01 higher than those in the lowest tertile.Our results demonstrate a higher circulating ANGPTL2 level in patients with HF, and the upregulating ANGPTL2 levels might be associated with metabolic derangements and inflammation.

    Diabetes is a serious metabolic disorder and oxidative stress and inflammation contribute to its pathogenesis and complications. Since Silybum marianum (L.) Gaertn. (silymarin) extract is an antioxidant with anti-inflammatory properties, this randomized clinical trial was conducted to evaluate the effects of silymarin supplementation on oxidative stress indices and hs-CRP in type 2 diabetes mellitus patients. For the present paralleled, randomized, triple-blinded, placebo-controlled clinical trial, 40 type 2 diabetes patients aged 25-50 yr old and on stable medication were recruited from the Iranian Diabetes Society and endocrinology clinics in East Azarbayjan (Tabriz, Iran) and randomly assigned into two groups. Patients in the silymarin treatment group received 140 mg, thrice daily of dried extracts of Silybum marianum (n = 20) and those in the placebo group (n = 20) received identical placebos for 45 days. Data pertaining to height, weight, waist circumference and BMI, as well as food consumption, were collected at base line and at the conclusion of the study. Fasting blood samples were obtained and antioxidant indices and hs-CRP were assessed at baseline, as well as at the end of the trial. All 40 patients completed the study and did not report any adverse effects or symptoms with the silymarin supplementation. Silymarin supplementation significantly increased superoxide dismutase (SOD), glutathione peroxidase (GPX) activity and total antioxidant capacity (TAC) compared to patients taking the placebo, by 12.85%, 30.32% and 8.43%, respectively (p concentration significantly decreased by 12.01% (p antioxidant indices (SOD, GPX and TAC) and decrease hs-CRP levels in T2DM patients.

    To meet expressed Member States' needs, the IAEA has initiated a Coordinated Research Project (CRP) on 'Studies of Advanced Reactor Technology Options for Effective Incineration of Radioactive Waste'. The final goal of the CRP is to deepen the understanding of the dynamics of transmutation systems, e.g. the accelerator driven system, especially systems with deteriorated safety parameters, qualify the available methods, specify the range of validity of methods, and formulate requirements for future theoretical developments. Should transient experiments be available, the CRP will pursue experimental benchmarking work. In any case, based on the results, the CRP will conclude on the potential need of transient experiments and make appropriate proposals for experimental programs. The Technical Meeting in Chennai was the 3rd Research Coordination Meeting (RCM) of the CRP The man objectives of the RCM were to: - Discuss and perform inter-comparisons of the various benchmark results; - Prepare the first draft of the final CRP Report Status of the analyses and inter-comparisons of the results. The main objective of the CRP was to study innovative technology options for incinerating/utilizing radioactive wastes. The CRP's benchmarking exercises focused on eight innovative transmutation 'Domains', which correspond to different critical and sub-critical concepts or groups of concepts: I. Critical fast reactor, solid fuel, with fertile; II. Critical fast reactor, solid fuel, fertile-free; III. ADS, solid fuel, with fertile; IV. ADS, solid fuel, fertile-free; V. Critical reactor and ADS, molten salt fuel, with fertile; VI. Critical reactor and ADS, molten salt fuel, fertile-free; VII. Critical fast reactor and ADS, gas cooled; VIII. Fusion/fission hybrid system. For each of these Domains, the discussions and inter-comparisons considered the following issues: - Reactor-models; - Scenarios/phenomena; - Static analyses; - Dynamic analyses; - Methods; - Codes; - Neutronic data base

    Insulin resistance (IR) is associated with low adiponectin and elevated high sensitivity C-reactive protein (hsCRP). Osteoprotegerin (OPG) has been shown to be elevated in type 2 diabetes, but whether it reflects underlying IR is unclear. We aimed to compare the ability of serum OPG with adiponectin and hsCRP to act as a marker for IR in individuals with normal and abnormal glucose tolerance.

    Full Text Available Objective: To investigate the effects of oxaliplatin, leucovorin and fluorouracil on serum tumor markers, VEGF, CRP and matrix metalloproteinases in patients with advanced esophageal cancer. Methods: From March 2012 to March 2017 a total of 248 patients with advanced esophageal cancer were selected as the study subjects. According to random data table, they were divided into control group (n=123 and observation group (n=125 according to random data table. The control group was treated with cisplatin combined with fluorouracil, leucovorin chemotherapy, and patients in the observation group received oxaliplatin, leucovorin and fluorouracil chemotherapy, all patients were treated for 2 cycles. The changes of serum tumor markers, VEGF, CRP and matrix metalloproteinase levels in the two groups before and after treatment was compared. Results: Before treatment, there was no significant difference of the levels of serum CA125, CA19-9, CEA, VEGF, CRP, MMP-2 and MMP-9 between the control group and the observation group. Compared with the group before treatment, the levels of CA125, CA19-9, CEA, VEGF, CRP, MMP-2 and MMP-9 in the two groups were significantly lower. After treatment, the level of CA125, CA19-9, CEA, VEGF, CRP, MMP-2 and MMP-9 in the observation group was significantly lower than those of the control group. Conclusion: Oxaliplatin, leucovorin and fluorouracil chemotherapy can effectively reduce the levels of serum tumor markers, VEGF, CRP and matrix metalloproteinase in patients with advanced esophageal cancer, it has important clinical value.

    Fibrosis is caused by scar tissue formation in internal organs and is associated with 45% of deaths in the United States. Two closely related human serum proteins, serum amyloid P (SAP) and C-reactive protein (CRP), strongly affect fibrosis. In multiple animal models, and in Phase 1 and Phase 2 clinical trials, SAP affects several aspects of the innate immune system to reduce fibrosis, whereas CRP appears to potentiate fibrosis. However, SAP and CRP bind the same Fcγ receptors (FcγR) with similar affinities, and why SAP and CRP have opposing effects is unknown. Here, we report that SAP but not CRP binds the receptor DC-SIGN (SIGN-R1) to affect the innate immune system, and that FcγR are not necessary for SAP function. A polycyclic aminothiazole DC-SIGN ligand and anti-DC-SIGN antibodies mimic SAP effects in vitro. In mice, the aminothiazole reduces neutrophil accumulation in a model of acute lung inflammation and, at 0.001 mg/kg, alleviates pulmonary fibrosis by increasing levels of the immunosuppressant IL-10. DC-SIGN (SIGN-R1) is present on mouse lung epithelial cells, and SAP and the aminothiazole potentiate IL-10 production from these cells. Our data suggest that SAP activates DC-SIGN to regulate the innate immune system differently from CRP, and that DC-SIGN is a target for antifibrotics.

    The evidence on the acute effects of smoking on biomarkers is limited. Our aim was to study the acute effect of smoking on disease-related biomarkers. The acute effect of smoking on serum high sensitivity CRP (hs-CRP) and plasma fibrinogen and its association with disease severity was studied by challenging 31 chronic obstructive pulmonary disease patients with cigarette smoking and repeatedly measuring these biomarkers before and after smoking. Fibrinogen and hs-CRP increased directly after smoking by 9.4 mg/dl (95% CI: 4.2-14.5) and 0.13 mg/l (95% CI: 0.03-0.23), respectively. Fibrinogen levels remained elevated after 35 min, whereas hs-CRP normalized. Pearson's correlation coefficient between the hs-CRP change and chronic obstructive pulmonary disease severity was 0.25 (p = 0.06). Fibrinogen and hs-CRP increased directly after smoking in the chronic obstructive pulmonary disease patients. Their association with disease risk and/or progression remains to be demonstrated.

    To compare the effects of the ACE inhibitor captopril with the calcium channel blocker amlodipine on serum CRP concentrations in hypertensive type 2 diabetic patients. This is a case control study conducted in Al-Wafa Diabetic Center in Mosul. Serum CRP concentrations were measured in two groups of hypertensive type 2 diabetic patients before and after drug administration (group 1 on captopril therapy, group two on amlodipine therapy). A significant reduction of serum CRP level was demonstrated after treatment with captopril but not with amlodipine. Mean CRP concentration of the control group was statistically lower than those of captopril and amlodipine groups. The present study showed that hypertensive type 2 diabetic patients are associated with increased level of CRP and therapy with captopril but not amlodipine significantly reduced CRP, suggesting a possible anti-inflammatory action of captopril in addition to its BP lowering effects thus captopril may be regarded as the drug of choice in the treatment of BP in diabetic hypertensive patients.

    Full Text Available Objective: In this study, it was aimed to compare the relationship between Glasgow Coma Scale (GKS, ISS values, PCT, CRP, D-Dimer, laktat, TNF-α, IL-1β, IL-6, IL-10 in patients with polytrauma and isolated head trauma in conjunction with SIRS and sepsis. Material and Method: Total of 68 patients (32 polytrauma, 36 isolated head trauma aged between 18-65 years were enrolled in the study. For 7 days of follow up, the biochemical parameters were analysed on the days 0, 1, 3, 5, 7 and the ISS, GCS score and growth rates of SIRS and sepsis were recorded. Results: It was demonstrated that for patients with isolated head trauma, SIRS (80.6%, sepsis (38.9% and mortality values (71.4% were higher and there is a statistically important linear and inverse relationship between ISS and GCS values (p<0.05. During sepsis and SIRS phases, CRP elevated in both groups, whereas PCT only in the polytrauma group. D-Dimer values were investigated high in both groups, but atypically decreased on day 3 in isolated head trauma group. Lactate, TNF-α and, IL-1β were within reference values, IL-6 and IL-10 values were elevated in both groups but were higher in the polytrauma group. Conclusion: Although multiple variations were detected in serum markers of pro-inflamatory and acute phase proteins, we thought that these are inadequate in predicting mortality and complications such as SIRS and sepsis.

    CRP-GEORC concept model is an artificial system of geological disposal for High-Level radioactive waste. Sensitivity analysis and uncertainties simulation of the migration of radionuclide Se-79 and I-129 in the far field of this system by using GoldSim Code have been conducted. It can be seen from the simulation results that variables used to describe the geological features and characterization of groundwater flow are sensitive variables of whole geological disposal system. The uncertainties of parameters have remarkable influence on the simulation results. (authors)

    Full Text Available BACKGROUND: Sleep restriction, leading to deprivation of sleep, is common in modern 24-h societies and is associated with the development of health problems including cardiovascular diseases. Our objective was to investigate the immunological effects of prolonged sleep restriction and subsequent recovery sleep, by simulating a working week and following recovery weekend in a laboratory environment. METHODS AND FINDINGS: After 2 baseline nights of 8 hours time in bed (TIB, 13 healthy young men had only 4 hours TIB per night for 5 nights, followed by 2 recovery nights with 8 hours TIB. 6 control subjects had 8 hours TIB per night throughout the experiment. Heart rate, blood pressure, salivary cortisol and serum C-reactive protein (CRP were measured after the baseline (BL, sleep restriction (SR and recovery (REC period. Peripheral blood mononuclear cells (PBMC were collected at these time points, counted and stimulated with PHA. Cell proliferation was analyzed by thymidine incorporation and cytokine production by ELISA and RT-PCR. CRP was increased after SR (145% of BL; p<0.05, and continued to increase after REC (231% of BL; p<0.05. Heart rate was increased after REC (108% of BL; p<0.05. The amount of circulating NK-cells decreased (65% of BL; p<0.005 and the amount of B-cells increased (121% of BL; p<0.005 after SR, but these cell numbers recovered almost completely during REC. Proliferation of stimulated PBMC increased after SR (233% of BL; p<0.05, accompanied by increased production of IL-1beta (137% of BL; p<0.05, IL-6 (163% of BL; p<0.05 and IL-17 (138% of BL; p<0.05 at mRNA level. After REC, IL-17 was still increased at the protein level (119% of BL; p<0.05. CONCLUSIONS: 5 nights of sleep restriction increased lymphocyte activation and the production of proinflammatory cytokines including IL-1beta IL-6 and IL-17; they remained elevated after 2 nights of recovery sleep, accompanied by increased heart rate and serum CRP, 2 important risk

    The hypothesized effect of vitamin D on C-reactive protein (CRP) has received substantial attention as a potential means to alleviate the risk for cardiovascular disease. However, observational studies have been inconsistent in their reporting of associations between serum 25-hydroxyvitamin D (25(OH)D) and CRP concentrations, and trials and meta analyses have been inconsistent in their conclusions regarding the effect of vitamin D supplementation on CRP concentrations. These supplementation trials were mostly conducted among patients with more or less inflammatory complications and did not consider potential distinctive effects by weight status. To further our understanding of the potential influences of vitamin D on CRP, we analyzed longitudinal observations of 6755 participants of a preventative health program. On average, serum 25(OH)D concentrations increased from 88.3 to 121.0 nmol/L and those of CRP decreased from 1.7 to 1.6 mg/L between baseline and follow up. Relative to obese participants without temporal increases in 25(OH)D, those who showed improvements of <25, 25-50, 50-75, and more than 75 nmol/L at follow up were 0.57 (95% confidence interval: 0.37-0.88), 0.54 (0.34-0.85), 0.49 (0.30-0.80), and 0.48 (0.29-0.78) times as likely to have elevated CRP concentrations (≥1 mg/L), respectively. These associations were less pronounced and not statistically significant for normal weight and overweight participants. Herewith, the findings suggest that promotion of adequate serum 25(OH)D concentrations among obese individuals along with healthy lifestyles may alleviate the public health burden associated with cardiovascular disease.

    CRP-ductin is a protein expressed mainly by mucosal epithelial cells in the mouse. Sequence homologies indicate that CRP-ductin is the mouse homologue of human gp-340, a glycoprotein that agglutinates microorganisms and binds the lung mucosal collectin surfactant protein-D (SP-D). Here we report...... that purified CRP-ductin binds human SP-D in a calcium-dependent manner and that the binding is not inhibited by maltose. The same properties have previously been observed for gp-340 binding of SP-D. CRP-ductin also showed calcium-dependent binding to both gram-positive and -negative bacteria. A polyclonal...... antibody raised against gp-340 reacted specifically with CRP-ductin in Western blots. Immunoreactivity to CRP-ductin was found in the exocrine pancreas, in epithelial cells throughout the gastrointestinal tract and in the parotid ducts. A panel of RNA preparations from mouse tissues was screened for CRP...

    region, and is sufficient for activation; the second site, CRP-2, centred around -93, is indispensable for repression. Here we demonstrate, by means of in vivo titration, that CytR interaction with deoP2 depends not only on CRP-2, but also on CRP-1 and the length and possibly the sequence separating...... these two sites. Also, point mutations in either CRP site reduce or abolish CytR titration; however, no co-operativity is observed in the interaction of CytR with the two CRP binding sites. Furthermore, the reduction in CytR titration parallels the reduction in binding of cAMP-CRP to the mutated CRP sites...

    Objective The association between pre-antiretroviral (ART) inflammation and immune activation and risk for incident tuberculosis (TB) after ART initiation among adults is uncertain. Design Nested case-control study (n = 332) within ACTG PEARLS trial of three ART regimens among 1571 HIV-infected, treatment-naïve adults in 9 countries. We compared cases (participants with incident TB diagnosed by 96 weeks) to a random sample of controls (participants who did not develop TB, stratified by country and treatment arm). Methods We measured pre-ART C-reactive protein (CRP), EndoCab IgM, ferritin, interferon gamma (IFN-γ), interleukin 6 (IL-6), interferon gamma-inducible protein 10 (IP-10), lipopolysaccharide (LPS), soluble CD14 (sCD14), tumor necrosis factor alpha (TNF-α), and CD4/DR+/38+ and CD8/DR+/38+ T cells. Markers were defined according to established cutoff definitions when available, 75th percentile of measured values when not, and detectable versus undetectable for LPS. Using logistic regression, we measured associations between biomarkers and incident TB, adjusting for age, sex, study site, treatment arm, baseline CD4 and log10 viral load. We assessed the discriminatory value of biomarkers using receiver operating characteristic (ROC) analysis. Results Seventy-seven persons (4.9%) developed incident TB during follow-up. Elevated baseline CRP (aOR 3.25, 95% CI: 1.55–6.81) and IP-10 (aOR 1.89, 95% CI: 1.05–3.39), detectable plasma LPS (aOR 2.39, 95% CI: 1.13–5.06), and the established TB risk factors anemia and hypoalbuminemia were independently associated with incident TB. In ROC analysis, CRP, albumin, and LPS improved discrimination only modestly for TB risk when added to baseline routine patient characteristics including CD4 count, body mass index, and prior TB. Conclusion Incident TB occurs commonly after ART initiation. Although associated with higher post-ART TB risk, baseline CRP, IP-10, and LPS add limited value to routine patient characteristics

    The verification and validation of computer codes used in the analysis of high temperature gas cooled pebble bed reactor systems has not been an easy goal to achieve. A limited amount of tests and operating reactor measurements are available. Code-to-code comparisons for realistic pebble bed reactor designs often exhibit differences that are difficult to explain and are often blamed on the complexity of the core models or the variety of analysis methods and cross section data sets employed. For this reason, within the framework of the IAEA CRP5, the 'Pebble Box' benchmark was formulated as a simple way to compare various treatments of neutronics phenomena. The problem is comprised of six test cases which were designed to investigate the treatments and effects of leakage and heterogeneity. This paper presents the preliminary results of the benchmark exercise as received during the CRP and suggests possible future steps towards the resolution of discrepancies between the results. Although few participants took part in the benchmarking exercise, the results presented here show that there is still a need for further evaluation and in-depth understanding in order to build the confidence that all the different methods, codes and cross-section data sets have the capability to handle the various neutronics effects for such systems.

    Full Text Available Background. There is a considerable dissimilarity in the survival duration of the patients with gastric cancer. We aimed to assess the systemic inflammatory response (SIR and nutritional status of these patients before the commencement of chemotherapy to find the appropriate prognostic factors and define a new score for predicting metastasis. Methods. SIR was assessed using Glasgow Prognostic Score (GPS. Then a score was defined as prealbumin/CRP based prognostic score (PCPS to be compared with GPS for predicting metastasis and nutritional status. Results. 71 patients with gastric cancer were recruited in the study. 87% of patients had malnutrition. There was a statistical difference between those with metastatic (n=43 and those with nonmetastatic (n=28 gastric cancer according to levels of prealbumin and CRP; however they were not different regarding patient generated subjective global assessment (PG-SGA and GPS. The best cut-off value for prealbumin was determined at 0.20 mg/dL and PCPS could predict metastasis with 76.5% sensitivity, 63.6% specificity, and 71.4% accuracy. Metastatic and nonmetastatic gastric cancer patients were different in terms of PCPS (P=0.005. Conclusion. PCPS has been suggested for predicting metastasis in patients with gastric cancer. Future studies with larger sample size have been warranted.

    Coronary heart disease (CHD) is an important public health problem globally. Algorithms incorporating the assessment of clinical biomarkers together with several established traditional risk factors can help clinicians to predict CHD and support clinical decision making with respect to interventions. Decision tree (DT) is a data mining model for extracting hidden knowledge from large databases. We aimed to establish a predictive model for coronary heart disease using a decision tree algorithm. Here we used a dataset of 2346 individuals including 1159 healthy participants and 1187 participant who had undergone coronary angiography (405 participants with negative angiography and 782 participants with positive angiography). We entered 10 variables of a total 12 variables into the DT algorithm (including age, sex, FBG, TG, hs-CRP, TC, HDL, LDL, SBP and DBP). Our model could identify the associated risk factors of CHD with sensitivity, specificity, accuracy of 96%, 87%, 94% and respectively. Serum hs-CRP levels was at top of the tree in our model, following by FBG, gender and age. Our model appears to be an accurate, specific and sensitive model for identifying the presence of CHD, but will require validation in prospective studies. Copyright © 2017 Elsevier B.V.

    Full Text Available Activation of adipose tissue inflammation is associated with obesity caused by lipid accumulation in adipocytes. Through this activation, proinflammatory cytokines, such as Interleukin-6 (IL-6 and C-reactive protein (CRP seem to influence metabolic disorders. The present study evaluated whether polymorphisms in the CRP (rs1205 and IL-6 (rs1800795, rs2069845 genes are associated with the development of metabolic disorders in children and adolescents. A cross-sectional study was performed, consisting of 470 students from the municipality of Santa Cruz do Sul, Brazil, aged 7-17 years. Body mass index (BMI was classified according to overweight and obesity. Genotyping was performed by real-time Polymerase Chain Reaction(PCR. Anthropometric characteristics, biochemical markers, immunological markers and blood pressure were assessed. Descriptive statistics, chi-square and logistic regression were used for the analyses. No association was detected between the rs1800795 polymorphism and the assessed variables. Individuals with the risk genotype in the rs1205 gene were associated with the risk of developing hypercholesterolemia (OR 2.79; CI 1.40, 5.57; p = 0.003. Carriers of the risk genotype in the rs2069845 gene are associated with the risk of developing obesity (OR 3.07; CI 1.08, 8.72; p = 0.03. The polymorphism rs2069845 was associated with obesity and rs1205 was associated with the risk of developing hypercholesterolemia in Brazilian schoolchildren.

    Objective: To evaluate the levels of C-reactive protein, an inflammatory marker in preeclamptic and normotensive pregnant women and to determine its correlation with fetal birth weight. Study Design: Cross-sectional analytical study. Place and Duration of Study: Unit of Obstetrics and Gynaecology, Shaikh Zayed Hospital and Gynaecological Unit II of Jinnah Hospital, Lahore, from December 2011 to May 2012. Methodology: The participants included 60 cases with preeclampsia and 60 normotensive pregnant women, all in their third trimester. All the participants were in the age group of 20 - 40 years and had a BMI range of 18 - 25. High sensitive C-reactive protein (hsCRP) levels were measured by Enzyme Link Immunosorbent Assay. Statistical analysis was done using SPSS (version 15). The values were considered significant at 0.05 level of significance. Results: C-reactive protein levels were significantly high (p < 0.001) in the preeclamptic group with a median value of 8.8 (0.3 - 25.5) as compared to 5.4 (0.24 - 9.8) mg/l in the normotensive women. The birth weight of babies was also significantly low in the preeclamptic group. The high CRP levels were negatively correlated with fetal birth weight in preeclamptic group. Conclusion: Elevated C-reactive protein levels in the preeclamptic pregnant women is a part of an exaggerated maternal systemic inflammatory response, and correlates with low fetal birth weight.

    A-Kinase anchoring proteins (AKAPs) coordinate the specificity of protein kinase A signaling by localizing the kinase to subcellular sites. The 1936G (V646) AKAP10 allele has been associated with adults with low cholinergic/vagus nerve sensitivity and with newborns with increased blood pressure. Decreased activity of the parasympathetic system is associated with risk of metabolic syndrome. The aim of this study was to answer the question of whether 1936A > G AKAP10 polymorphism is associated with metabolic changes in full-term newborns that are predictive factors for the metabolic phenotype in adulthood. The study included 114 consecutive healthy Polish newborns born after the end of the 37 th week of gestation to healthy women with uncomplicated pregnancies. At birth, cord blood of neonates was obtained for isolation of genomic DNA and cholesterol as well as triglyceride concentration. The cholesterol level in homozygotes GG was significantly higher than that in 1936A variant carriers (AG + AA, recessive mode of inheritance). Our results demonstrate a possible association between the 1936G AKAP10 variant and the total cholesterol level in the cord blood of the Polish newborn population.

    Measurement of plasma levels of protein-conjugated acrolein (PC-Acro) together with IL-6 and CRP can be used to identify silent brain infarction (SBI) with high sensitivity and specificity. The aim of this study was to determine how these biomarkers vary during stroke. Levels of PC-Acro, IL-6 and CRP in plasma were measured on day 0, 2, 7 and 14 after the onset of ischemic or hemorrhagic stroke. After the onset of stroke, the level of PC-Acro in plasma was elevated corresponding to the size of stroke. It returned to near control levels by day 2, and remained similar through day 14. The degree of the decrease in PC-Acro on day 2 was greater when the size of brain infarction or hemorrhage was larger. An increase in IL-6 and CRP occurred after the increase in PC-Acro, and it was well correlated with the size of the injury following infarction or hemorrhage. The results suggest that acrolein becomes a trigger for the production of IL-6 and CRP, as previously observed in a mouse model of stroke and in cell culture systems. The increase in IL-6 and CRP was also correlated with poor outcome judging from mRS. The results indicate that the degree of the decrease in PC-Acro and the increase in IL-6 and CRP from day 0 to day 2 was correlated with the size of brain infarction, and the increase in IL-6 and CRP with poor outcome at discharge.

    Early recognition of severe form of acute pancreatitis is important because these patients need more agressive diagnostic and therapeutical approach an can develope systemic complications such as: sepsis, coagulopathy, Acute Lung Injury (ALI), Acute Respiratory Distress Syndrome (ARDS), Multiple Organ Dysfunction Syndrome (MODS), Multiple Organ Failure (MOF). To determine role of the combination of Systemic Inflammatory Response Syndrome (SIRS) score and serum Interleukin-6 (IL-6) level on admission as predictor of illness severity and outcome of Severe Acute Pancreatitis (SAP). We evaluated 234 patients with first onset of SAP appears in last twenty four hours. A total of 77 (33%) patients died. SIRS score and serum IL-6 concentration were measured in first hour after admission. In 105 patients with SIRS score 3 and higher, initial measured IL-6 levels were significantly higher than in the group of remaining 129 patients (72 +/- 67 pg/mL, vs 18 +/- 15 pg/mL). All nonsurvivals were in the first group, with SIRS score 3 and 4 and initial IL-6 concentration 113 +/- 27 pg/mL. The values of C-reactive Protein (CRP) measured after 48h, Acute Physiology and Chronic Health Evaluation (APACHE II) score on admission and Ranson score showed the similar correlation, but serum amylase level did not correlate significantly with Ranson score, IL-6 concentration and APACHE II score. The combination of SIRS score on admission and IL-6 serum concentration can be early, predictor of illness severity and outcome in SAP.

    Cysteine-rich secretory proteins (CRISPs) are commonly described as part of the protein content of snake venoms, nevertheless, so far, little is known about their biological targets and functions. Our study describes the isolation and characterization of Bj-CRP, the first CRISP isolated from Bothrops jararaca snake venom, also aiming at the identification of possible targets for its actions. Bj-CRP was purified using three chromatographic steps (Sephacryl S-200, Source 15Q and C18) and showed to be an acidic protein of 24.6kDa with high sequence identity to other snake venom CRISPs. This CRISP was devoid of proteolytic, hemorrhagic or coagulant activities, and it did not affect the currents from 13 voltage-gated potassium channel isoforms. Conversely, Bj-CRP induced inflammatory responses characterized by increase of leukocytes, mainly neutrophils, after 1 and 4h of its injection in the peritoneal cavity of mice, also stimulating the production of IL-6. Bj-CRP also acted on the human complement system, modulating some of the activation pathways and acting directly on important components (C3 and C4), thus inducing the generation of anaphylatoxins (C3a, C4a and C5a). Therefore, our results for Bj-CRP open up prospects for better understanding this class of toxins and its biological actions. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Abstract Background The cysteine and glycine rich protein 2 (CRP2 encoded by the Csrp2 gene is a LIM domain protein expressed in the vascular system, particularly in smooth muscle cells. It exhibits a bimodal subcellular distribution, accumulating at actin-based filaments in the cytosol and in the nucleus. In order to analyze the function of CRP2 in vivo, we disrupted the Csrp2 gene in mice and analysed the resulting phenotype. Results A ~17.3 kbp fragment of the murine Csrp2 gene containing exon 3 through 6 was isolated. Using this construct we confirmed the recently determined chromosomal localization (Chromosome 10, best fit location between markers D10Mit203 proximal and D10Mit150 central. A gene disruption cassette was cloned into exon 4 and a mouse strain lacking functional Csrp2 was generated. Mice lacking CRP2 are viable and fertile and have no obvious deficits in reproduction and survival. However, detailed histological and electron microscopic studies reveal that CRP2-deficient mice have subtle alterations in their cardiac ultrastructure. In these mice, the cardiomyocytes display a slight increase in their thickness, indicating moderate hypertrophy at the cellular level. Although the expression of several intercalated disc-associated proteins such as β-catenin, N-RAP and connexin-43 were not affected in these mice, the distribution of respective proteins was changed within heart tissue. Conclusion We conclude that the lack of CRP2 is associated with alterations in cardiomyocyte thickness and hypertrophy.

    The fundamental design for a gas-cooled reactor relies on an understanding of the behavior of a coated particle fuel. KAERI, which has been carrying out the Korean VHTR (Very High Temperature modular gas cooled Reactor) Project since 2004, is developing a fuel performance analysis code for a VHTR named COPA (COated Particle fuel Analysis). COPA predicts temperatures, stresses, a fission gas release and failure probabilities of a coated particle fuel in normal operating conditions. Validation of COPA in the process of its development is realized partly by participating in the benchmark section of the international CRP-6 program led by IAEA which provides comprehensive benchmark problems and analysis results obtained from the CRP-6 member countries. Apart from the validation effort through the CRP-6, a validation of COPA was attempted by comparing its benchmark results with the visco-elastic solutions obtained from the ABAQUS code calculations for the same CRP-6 TRISO coated particle benchmark problems involving creep, swelling, and pressure. The study shows the calculation results of the IAEA-CRP-6 benchmark cases 5 through 7 by using the ABAQUS FE model for a comparison with the COPA results

    Due to improved access and adherence to antiretroviral therapy (ART), most HIV-infected persons worldwide are predicted to live longer. Nowadays the cause of death for most HIV-infected persons has changed to serious non-AIDS events (SNAEs) which is due to low-grade viremia. HIV patients with ART who had undergone CD4 cell count above 500/uL and there is an increase in hs-CRP despite an undetectable viral load. Some conditions CD8 cells count do not decrease with CD4 cells repairs. We researched in Prof Kandou General Hospital with a total sample of 35 HIV patients who had received ART with the level of CD4>350/uL. CD8 levels, CD4/CD8 ratio, and hs-CRP were assessed. This research is analytic descriptive with cross-sectional study design and analysis uses Spearman correlation. The mean CD8 during the study was 1291.8 (IQR 319-2610cells/uL), the mean ratio of CD4:CD8 was 0.57 (IQR 0.16-1.24) and median hs-CRP is 2.18 (IQR 0.3-6.6mg/dL). There was a significant positive correlation between CD8 and increased hs-CRP (r=0.369, pCD4/CD8 ratio and hs-CRP (r=-0.370, p<0.05).

    Objective: To study the clinical significance of determination of changes of plasma levels of intermedin (IMD), BNP and CRP in patients with chronic heart failure. Methods: Plasma IMD, BNP (with RIA) and CRP (with immuno-turbidity) levels were determined in 46 patients with chronic heart failure of various grades (grade I-II n=31, grade III-IV, n=15) and 42 normal controls. Results: Compared with the control group,the plasma IMD level in patients with chronic heart failure was decreased 53.2% (P<0.01), the BNP and CRP were increased 1658.5% and 80.5% respectively (each P<0.001). Compared with the grade I-II group, the plasma IMD level in grade III-IV was decreased 34.7% (P<0.05), the BNP and CRP levels in grade III-IV were increased 257.8% and 76% (all P<0.001) individually. Conclusion: Plasma intermedin concentration was significantly decreased in patients with chronic heart failure, which suggests that they play an important role in the pathogenesis of chronic heart failure.

    Increased C-reactive protein levels have been found in all active inflammations, including periodontitis. This study aims to assess the C-reactive protein levels in periodontal disease progression. Forty-five patients were divided into the following three groups (n=15) based on gingival index, probing pocket depth, and clinical attachment level: healthy (group I), gingivitis (group II), and chronic periodontitis (group III). Gingival crevicular fluid and serum samples were quantified for C-reactive protein using enzyme-linked immunosorbent assay. The mean C-reactive protein concentration in gingival crevicular fluid and serum was found to be highest in group III (1233.33ng/mL for gingival crevicular fluid, 5483.33ng/mL for serum), and least in group I (60 ng/mL and 413 ng/mL for gingival crevicular fluid and serum, respectively) The mean C-reactive protein concentration in group II (453.33ng/mL for gingival crevicular fluid and 3565.33 ng/mL for serum) was found to be intermediate. C-reactive protein levels in gingival crevicular fluid and serum increased proportionately with the severity of periodontal disease. They correlated positively with clinical parameters, including gingival index, probing pocket depth, and clinical attachment level. Thus, it can be considered as a periodontal inflammatory biomarker and deserves further consideration. © 2010 Blackwell Publishing Asia Pty Ltd.

    Whole-body cryotherapy refers to brief exposure to very cold air for treating symptoms of various illnesses. In sports medicine, whole-body cryotherapy is administered to improve recovery from muscular trauma. As specific studies are lacking, we measured cardiac markers in 10 top-level rugby players of the Italian National team before and after a 1-week course of daily sessions of whole-body cryotherapy. All subjects continued with the same training workload as that of the previous weeks. N-terminal pro B-type natriuretic peptide (NTproBNP) levels increased but remained within the normal range, whilst troponin I (TnI) and high sensitivity C-reactive protein (hsCRP) were unchanged. Whole-body cryotherapy did not impair cardiac function in this sample of elite athletes.

    Osteoarthritis (OA) is degenerative and inflammatory joint diseases. Management of OA, until now limited only to overcome the pain, inflammation, and improvement of joint function with medication in the form of NSAIDs that have many side effects. Damage to cells due to the stimulus will free various mediators or substances inflammation such as prostaglandin, IL-6, TNF-α and nitric oxide. Sidaguri plant (Sidarhombifolia L) has anti-inflammatory activity by inhibition of nitric oxide. The mechanism of action Meloxicam, like other NSAIDs, may be associated with the inhibition of prostaglandin synthetase (cyclo-oxygenase). One of the markers of the inflammatory process is CRP and ESR. We tested 50 patients divided into two groups, patients who get Meloxicam and Sidaguri (n = 25) and patients who get Meloxicam and placebo (n = 25). There were significant changes before and after therapy with p-value<0.0001.

    A dual-analyte assay for the simultaneous determination of C-reactive protein (CRP) and D-dimer in human blood plasma based on a white light interference spectroscopy sensing platform is presented. Measurement is accomplished in real-time by scanning the sensing surface, on which distinct antibody areas have been created, with a reflection probe used both for illumination of the surface and collection of the reflected interference spectrum. The composition of the transducer, the sensing surface chemical activation and biofunctionalization procedures were optimized with respect to signal magnitude and repeatability. The assay format involved direct detection of CRP whereas for D-dimer a two-site immunoassay employing a biotinylated reporter antibody and reaction with streptavidin was selected. The assays were sensitive with detection limits of 25ng/mL for both analytes, precise with intra- and inter-assay CV values ranging from 3.6% to 7.7%, and from 4.8% to 9.5%, respectively, for both assays, and accurate with recovery values ranging from 88.5% to 108% for both analytes. Moreover, the values determined for the two analytes in 35 human plasma samples were in excellent agreement with those received for the same samples by standard diagnostic laboratory instrumentation employing commercial kits. The excellent agreement of the results supported the validity of the proposed system for clinical application for the detection of multiple analytes since it was demonstrated that up to seven antibody areas can be created on the sensing surface and successfully interrogated with the developed optical set-up.

    Full Text Available Serial C-reactive protein (CRP values may be useful for decision-making regarding duration of antibiotics in neonates. However, established standard of practice for its use in preterm very low birth weight (<1500 g, VLBW infants are lacking.Evaluate compliance with a CRP-guided computerized decision support (CDS algorithm and compare characteristics and outcomes of compliant versus non-compliant cases. Measure correlation between CRPs and white blood count (WBC indices.We examined 3 populations: 1 all preterm VLBW infants born at Vanderbilt 2006-2011 - we assessed provider compliance with CDS algorithm and measured relevant outcomes; 2 all patients with positive blood culture results admitted to the Vanderbilt NICU 2006-2012 - we tested the correlation between CRP and WBC results within 7 days of blood culture phlebotomy; 3 1,000 randomly selected patients out of the 7,062 patients admitted to the NICU 2006-2012 - we correlated time-associated CRP values and absolute neutrophil counts.Of 636 VLBW infants in cohort 1, 569 (89% received empiric antibiotics for suspected early-onset sepsis. In 409 infants (72% the CDS algorithm was followed; antibiotics were discontinued ≤48 hours in 311 (55% with normal serial CRPs and continued in 98 (17% with positive CRPs, resulting in significant reduction in antibiotic exposure (p<0.001 without increase in complications or subsequent infections. One hundred sixty (28% were considered non-compliant because antibiotics were continued beyond 48 hours despite negative serial CRPs and blood cultures. Serial CRPs remained negative in 38 (12% of 308 blood culture-positive infants from cohort 2, but only 4 patients had clinically probable sepsis with single organisms and no immunodeficiency besides extreme prematurity. Leukopenia of any cell type was not linked with CRPs in cohorts 2 and 3.CDS/CRP-guided antibiotic use is safe and effective in culture-negative VLBW infants. CRP results are not affected by low WBC

  7. Fumaric acid esters can block pro-inflammatory actions of human CRP and ameliorate metabolic disturbances in transgenic spontaneously hypertensive rats.

    Full Text Available Inflammation and oxidative stress have been implicated in the pathogenesis of metabolic disturbances. Esters of fumaric acid, mainly dimethyl fumarate, exhibit immunomodulatory, anti-inflammatory, and anti-oxidative effects. In the current study, we tested the hypothesis that fumaric acid ester (FAE treatment of an animal model of inflammation and metabolic syndrome, the spontaneously hypertensive rat transgenically expressing human C-reactive protein (SHR-CRP, will ameliorate inflammation, oxidative stress, and metabolic disturbances. We studied the effects of FAE treatment by administering Fumaderm, 10 mg/kg body weight for 4 weeks, to male SHR-CRP. Untreated male SHR-CRP rats were used as controls. All rats were fed a high sucrose diet. Compared to untreated controls, rats treated with FAE showed significantly lower levels of endogenous CRP but not transgenic human CRP, and amelioration of inflammation (reduced levels of serum IL6 and TNFα and oxidative stress (reduced levels of lipoperoxidation products in liver, heart, kidney, and plasma. FAE treatment was also associated with lower visceral fat weight and less ectopic fat accumulation in liver and muscle, greater levels of lipolysis, and greater incorporation of glucose into adipose tissue lipids. Analysis of gene expression profiles in the liver with Affymetrix arrays revealed that FAE treatment was associated with differential expression of genes in pathways that involve the regulation of inflammation and oxidative stress. These findings suggest potentially important anti-inflammatory, anti-oxidative, and metabolic effects of FAE in a model of inflammation and metabolic disturbances induced by human CRP.

    To study the effect of strict prolonged fasting on lipid profile, serum leptin, and high- sensitivity C-reactive protein (hs-CRP) in patients with different stable cardiac illnesses and look for associated new cardiac events and any correlation between entire variables. A total of 56 patients of different stable cardiac illnesses were followed in our cardiology outpatient for 3 months. Data concerning their ability to fast were collected: New York Heart Association class of congestive cardiac failure, angina class, previous myocardial infarction, previous coronary artery bypass graft, percutaneous coronary intervention, severity of valvular lesion, metallic prosthetic valve, and traditional risk factors (diabetes mellitus, insulin requirement, hypertension, hypercholesterolemia, smoking habit, and obesity). Detailed clinical examination and electrocardiography were performed in all patients in three consecutive visits before, during, and after Ramadan. Echocardiographic and angiographic findings and medication plans were collected from patient records. Lipid profile, serum leptin, and hs-CRP were assessed before, during, and after Ramadan. All patients fasted during Ramadan: 80.4% were male, 67.9% were aged >50 years, 71.4% had no change in their symptoms during fasting while 28.6% felt better. No patient has deteriorated. 91.1% of the patients were compliant with medicine during Ramadan, 73.2% after. 89.3% were compliant with diet during Ramadan with no significant change in body weight in the follow-up period. No cardiac or noncardiac morbidity or mortality was reported. High- density lipoprotein-cholesterol (HDL-C) decreased significantly during compared to before fasting (P = 0.012). Low-density lipoprotein-cholesterol (LDL-C) significantly increased during compared to before fasting (P = 0.022). No statistically significant changes were observed in total cholesterol (TC), triglycerides (TG), serum leptin, or hs-CRP. Significant correlation was observed between

    Hepcidin has emerged as a peptide with a key role in the regulation of iron homeostasis in patients with chronic kidney disease (CKD), having a strong dependence on inflammation. Recent studies reveal that hepcidin may be also associated with the progression of atherosclerosis. This study was performed to analyze the relation of hepcidin to markers of atherosclerosis and inflammation in patients on dialysis. A total of 90 individuals were enrolled. Sixty patients with end-stage renal disease, who were on hemodialysis (HD) (N = 30) and peritoneal dialysis (N = 30) were compared with 30 normal controls (NC). Age, body mass index, time on dialysis, serum lipids, C-reactive protein (CRP) and interleukin-6 (IL-6) were measured and analyzed in correlation with hepcidin concentration. It was found that patients on HD and peritoneal dialysis have significantly higher (P triglycerides (r = 0.401, P = 0.005), HDL-C (r = -0.268, P = 0.048), CRP (r = 0.436, P = 0.0007) and IL-6 (r = 0.569, P triglycerides (β = 0.402, P = 0.041) and IL-6 (β = 0.559, P = 0.006). Moreover, patients with high triglycerides in combination with high IL-6 levels have significantly increased concentrations of hepcidin than those with low triglycerides and low IL-6 levels (P triglycerides and high IL-6 serum concentrations. This probably suggests that hepcidin may play a role to the progression of atherosclerosis and inflammation, but this hypothesis should be further evaluated. © 2013 The Authors.

    Full Text Available Background & Objective: High levels of homocysteine inflammatory markers and C-Reactive Protein (CRP cause many complications, including atherosclerosis, venous thrombosis, and cardiovascular problems. The objective of the present study was to investigate the effect of 12-weekHigh Intensity Interval Training (HIIT on homocysteine, CRP, and body composition in overweight men. Materials & Methods: In this quasi-experimental study, 20 students of Kashan University of Medical Sciences with a body mass index between 25 and 30 kg/m2, were purposefully selected and were randomly divided into experimental and control groups. The experimental group had practiced in the HIIT program with the intensity of up to 90 percent of maximum heart rate for 12 weeks. Before and after exercise, the amount of homocysteine, CRP, weight, body fat percentage, body mass index, and waist-to-hip ratio were calculated. The data were analyzed by using dependent and independent t-test at a significance level of P<0.05. Results: The results showed that12 weeks of HIIT had significant effects on reducing serum levels of homocysteine and HSCRP, body weight, body fat percentage, BMI, and WHR in the experimental group compared to the control group (P<0.05. Conclusion: It seems that 12 weeks of intense interval training as a non-invasive method can have a positive effect on reducing the amount of homocysteine, HS-CRP, and some anthropometric indexes of obesity and overweight.

    Arterial macrophages comprise a heterogeneous population: pro-inflammatory (M1) and anti-inflammatory (M2). Since C-reactive protein (CRP) is produced by macrophages in atherosclerotic lesions, understanding of CRP regulation in macrophages could be crucial to decipher inflammatory patterns in atherogenesis. We aimed to analyze CRP expression in M1/M2 macrophages and to question whether it involves NFκB signaling pathway. Furthermore, we questioned whether oxidative stress affect macrophage phenotype and modulate macrophage CRP expression. M1/M2 macrophage polarization was validated using THP-1 macrophages. CRP mRNA and protein expression were determined using real-time PCR and immunohistochemistry. Involvement of NFκB was determined by nuclear translocation of p50 subunit and the use of NFκB inhibitor. Involvement of oxidative stress in macrophage phenotypes induction was studied using oxidized-LDL (Ox-LDL) and antioxidants. M1 macrophages were characterized by elevated CRP mRNA expression (by 67%), CRP protein levels (by 108%), and upregulation of NFκB activation compared to control, but these features were not shared by M2 macrophages. Macrophages incubation with Ox-LDL led to a moderate M1 phenotype combined with a M2 phenotype, correlated with increased CRP mRNA expression. Antioxidants inhibited by up to 86% IL6 expression but did not significantly affect IL10 secretion. Antioxidants significantly inhibited CRP expression in M1 macrophages, but not in M2 macrophages. Elevated expression of CRP was characteristic of M1 macrophages rather than M2 through NFκB activation. Oxidative stress could be one of the endogenous triggers for macrophage activation to a mixed M1 and M2 phenotype, in association with increased expression of CRP.

    Herein, we studied the effects of two different exercise protocols on IL-17 and CRP plasma levels along with the anti-inflammatory effects of fish oil. The purpose of the present study was to investigate the effect of Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) consumption along with two different types of physical activities on IL-17 and CRP plasma levels in trained male mice. A total of 130 adult male mice of Syrian race with the age of 2 months and the weight of 35±1 grams were selected. At the beginning, 10 mice were killed in order to determine the amounts of pre-test variables. The rest of the mice were randomly divided into 6 groups including control group (n=20), supplement (n=20), aerobic exercise (n=20), anaerobic exercise (n=20), supplementaerobic exercise (n=20), and supplement-anaerobic exercise (n=20). Blood samples were withdrawn from the tail under intraperitoneal ketamine and xylasine anaesthesia. The anaerobic training program included 8 weeks of running on treadmill, 3 sessions per week; the aerobic training program included 8 weeks of running on treadmill, 5 sessions per week. At the end of the training program, the blood sample from each group was taken in order to measure the CRP and IL-17 levels. The analysis of variance (ANOVA) was used to determine the differences among the groups. The results showed that there was a significant difference in IL-17 and CRP plasma levels between the groups after 8 weeks (Ptraining programs, both IL-17 and CRP plasma levels increased, although these observed increases were not same for two measured variables. The results might also show that the effect of the supplement depends on the type of training.

    Metastatic colorectal cancer (mCRC) is a lethal disease and fluorouracil-leucovorin-irinotecan (FOLFIRI) plus bevacizumab (bev) is a standard approach. Hence, there is a strong need for identifying new prognostic factors to show the efficacy of FOLFIRI-bev. This is a retrospective study including patients (n = 90) with mCRC from two centers in Turkey. Neutrophil/lymphocyte (N/L) ratio, platelet count, albumin, and C-reactive protein (CRP) were recorded before FOLFIRI-bev therapy. The efficacy of these factors on progression-free survival (PFS) was analyzed with Kaplan Meier and Cox regression analysis. And the cutoff value of N/L ratio was analyzed with ROC analysis. The median age was 56 years (range 21-80). Forty-seven percent of patients with N/L ratio >2.5 showed progressive disease versus 43 % in patients with N/L ratio ratio >2.5 versus 13.5 months for the patients with N/L ratio analysis, high baseline neutrophil count, LDH, N/L ratio, and CRP were all significantly associated with poor prognosis. At multivariate Cox regression analysis, CRP was confirmed to be a better independent prognostic factor. CRP variable was divided into above the upper limit of normal (ULN) and normal value. The median PFSs of the patients with normal and above ULN were 11.3 versus 5.8 months, respectively (p = 0.022). CRP and N/L ratio are potential predictors for advanced mCRC treated with FOLFIRI-bev.

    Objective: To determine the correlation between CRP (C-reactive protein) and Waist to Hip Ratio (WHR) among over weight and obese patients with normal blood pressure. Study Design: An analytical study. Place and Duration of Study: Medical indoor and outpatient clinics of Mayo Hospital, Lahore, from March to August 2013. Methodology: Willing patients with Body Mass Index (BMI) of > 23 kg/m2, normal blood pressures, and age between 18 - 65 years were inducted in the study. Patients with signs of fluid retention, collagen vascular disease, CAD, on corticosteroids, immunomodulators or lipid lowering medications, hypertensives and febrile patients were excluded. Patients were considered to be at low risk for cardiovascular events if WHR among males and females was < 0.95 and < 0.80, respectively. Similarly, males and females with WHR > 1 and > 0.85, respectively were taken as high risk. Levels in-between these ranges were taken as moderate risk. Data was analyzed on SPSS 15. Descriptive statistics were determined. The p-value was calculated by ANOVA and independent sample t-test among males and females respectively, to compare WHR in relation to different CRP levels and < 0.05 was taken as significant. Results: There were 34 male and 74 female patients. The gender-wise mean WHR did not show statistically significant difference categorized CRP levels (p=0.072 in male, and 0.052 in females). There was an increasing trend in CRP levels as WHR increased among females, but this was statistically insignificant (p=0.05). Conclusion: Although the impact of central obesity on cardiac health is well known, however, WHR alone is an unreliable indicator of systemic inflammation and raised CRP level. (author)

    BACKGROUND: Low-grade chronic inflammation is a characteristic feature of obesity, the most important lifestyle risk factor for hypertension. Elevated plasma concentrations of the inflammatory biomarker C-reactive protein (CRP) are associated with an increased risk of hypertension, but elevated...... plasma CRP concentrations are also closely associated with obesity. It is uncertain whether CRP is directly involved in the pathogenesis of hypertension or is only a marker of other pathogenic processes closely related to obesity. METHODS: We studied 103 obese men (body mass index (BMI) ≥ 30.0 kg/m(2......)); 63 of these men had 24-hour ambulatory blood pressure (ABP) ≥ 130/80 mm Hg and comprised the obese hypertensive (OHT) group.

    Nonimaging optics is a field devoted to the design of optical components for applications such as solar concentration or illumination. In this field, many different techniques have been used to produce optical devices, including the use of reflective and refractive components or inverse engineering techniques. However, many of these optical components are based on translational symmetries, rotational symmetries, or free-form surfaces. We study a new family of nonimaging concentrators called elliptical concentrators. This new family of concentrators provides new capabilities and can have different configurations, either homofocal or nonhomofocal. Translational and rotational concentrators can be considered as particular cases of elliptical concentrators.

    Multiple studies have found a direct relationship between leptin concentrations and disease activity in rheumatoid arthritis. We studied 77 patients with the diagnosis of rheumatoid arthritis; the leptin determination was through an enzyme immunoassay. Disease activity was assessed by the DAS-28 CRP. A multivariate logistic regression model was used to determine the association between significant variables and leptin concentrations. 40.3% of the patients were in remission, 41.6% were mildly active, 11.7% were moderately active and 6.5% were severely active. The results show an independent association between higher concentrations of leptin and disease activity (OR 1.7; 95% CI 1.4-3.2; p .03), the number of swollen joints (OR 4.6; 95% CI 1.7-8.3; p .000), the number of painful joints (OR 3.4; 95% CI 1.6-4.6; p .000), and the presence of metabolic syndrome (OR 1.3; 95% IC 1.2-1,9; p .045). The data suggest that serum leptin is elevated in patients with active RA. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    The overall objective of the CRP is to improve the Member States’ analytical capabilities in the field of fast reactor in-vessel sodium thermal hydraulics. A necessary condition towards achieving this objective is a wide international validation effort of the data and codes currently employed for the simulation of the various physical effects involved in this field. Therefore, in providing the required wide international basis of interested Member States, each applying different methodologies, the CRP will contribute towards achieving the stated objective with the help of benchmark exercises focusing, in a first stage, on the numerical simulation of temperature stratification of sodium observed in the Monju reactor vessel at a turbine trip test conducted in December 1995 during the original start-up experiments, and with the help of a thorough assessment of the calculation versus measured data comparisons

    Serum C-reactive protein (CRP) concentrations have been reported to be associated with body fat, especially visceral fat accumulation, but most studies up to now have been conducted on non-diabetic subjects. In this study, we investigated the association between the serum CRP concentrations and parameters of adiposity and insulin resistance in both Japanese type 2 diabetes patients and non-diabetic subjects. A total of 248 Japanese subjects (140 type 2 diabetes patients and 108 non-diabetic subjects) were enrolled for the study. The degree of insulin resistance was estimated by the homeostasis model assessment (HOMA-R) method. Fat accumulation was evaluated by measuring visceral and subcutaneous fat areas at the level of the umbilicus in abdominal CT scans. To assess hepatic fat content, the ratio of CT attenuation value of the liver to that of the spleen (L/S ratio) was calculated. Serum CRP was found to be significantly correlated with various indices of adiposity, including L/S ratio, visceral fat area (VFA), subcutaneous fat area (SFA), and HOMA-R, in both the diabetic patients and the non-diabetic subjects. After adjustment for five variables (age, gender, serum CRP, HbAlc, and smoking), serum CRP was still significantly correlated with L/S ratio, VFA, SFA, and HOMA-R in the diabetic patients. We also found that changes in serum CRP concentrations were correlated with changes in the VFA and SFA at 1 year after the baseline in 24 diabetic patients. We conclude that serum CRP may be closely related to the degree of liver steatosis and visceral fat accumulation in Japanese type 2 diabetes mellitus patients. (author)

  15. aldB, an RpoS-dependent gene in Escherichia coli encoding an aldehyde dehydrogenase that is repressed by Fis and activated by Crp.

    Escherichia coli aldB was identified as a gene that is negatively regulated by Fis but positively regulated by RpoS. The complete DNA sequence determined in this study indicates that aldB encodes a 56.3-kDa protein which shares a high degree of homology with an acetaldehyde dehydrogenase encoded by acoD of Alcaligenes eutrophus and an aldehyde dehydrogenase encoded by aldA of Vibrio cholerae and significant homology with a group of other aldehyde dehydrogenases from prokaryotes and eukaryotes. Expression of aldB is maximally induced during the transition from exponential phase to stationary phase. Its message levels are elevated three- to fourfold by a fis mutation and abolished by an rpoS mutation. In addition, the expression of an aldB-lacZ fusion was decreased about 20-fold in the absence of crp. DNase I footprinting analysis showed that five Fis binding sites and one Crp binding site are located within the aldB promoter region, suggesting that Fis and Crp are acting directly to control aldB transcription. AldB expression is induced by ethanol, but in contrast to that of most of the RpoS-dependent genes, the expression of aldB is not altered by an increase in medium osmolarity.

  16. A Serratia marcescens PigP homolog controls prodigiosin biosynthesis, swarming motility and hemolysis and is regulated by cAMP-CRP and HexS.

    Directory of Open Access Journals (Sweden)

    Robert M Q Shanks

    Full Text Available Swarming motility and hemolysis are virulence-associated determinants for a wide array of pathogenic bacteria. The broad host-range opportunistic pathogen Serratia marcescens produces serratamolide, a small cyclic amino-lipid, that promotes swarming motility and hemolysis. Serratamolide is negatively regulated by the transcription factors HexS and CRP. Positive regulators of serratamolide production are unknown. Similar to serratamolide, the antibiotic pigment, prodigiosin, is regulated by temperature, growth phase, HexS, and CRP. Because of this co-regulation, we tested the hypothesis that a homolog of the PigP transcription factor of the atypical Serratia species ATCC 39006, which positively regulates prodigiosin biosynthesis, is also a positive regulator of serratamolide production in S. marcescens. Mutation of pigP in clinical, environmental, and laboratory strains of S. marcescens conferred pleiotropic phenotypes including the loss of swarming motility, hemolysis, and severely reduced prodigiosin and serratamolide synthesis. Transcriptional analysis and electrophoretic mobility shift assays place PigP in a regulatory pathway with upstream regulators CRP and HexS. The data from this study identifies a positive regulator of serratamolide production, describes novel roles for the PigP transcription factor, shows for the first time that PigP directly regulates the pigment biosynthetic operon, and identifies upstream regulators of pigP. This study suggests that PigP is important for the ability of S. marcescens to compete in the environment.

    The shift away from traditional lifestyle in the Inuit population over the past few decades has been associated with an increased prevalence of coronary heart disease (CHD) risk factors such as obesity, high blood pressure (BP) and diabetes. However, the impact of this transition on the pro-inflammatory marker high-sensitivity C-reactive protein (hs-CRP) has not been documented. To examine the prevalence of elevated plasma hs-CRP concentrations in Inuit from Nunavik in the province of Quebec (Canada) and identify anthropometric, biochemical and lifestyle risk factors associated with elevated hs-CRP. A population-representative sample of 801 Inuit residents from 14 villages of Nunavik, aged between 18 and 74 years, was included in the analyses. Subjects participated in a clinical session and completed questionnaires on lifestyle. Multivariate logistic regression was used to determine risk factors for elevated hs-CRP. Elevated plasma hs-CRP concentrations (≥ 2 mg/L) were present in 32.7% (95% confidence interval (CI) 29.5-35.8) of the Inuit adult population and were more prevalent among women than among men (36.7% vs. 29.0%, p=0.007). Multivariate logistic regression analysis indicated that every 1 mmHg increase in systolic BP was associated with a 3% increase in the odds of having hs-CRP concentrations ≥ 2 mg/L in the Inuit population (95% CI 1.01-1.04). The combination of older age (≥ 50 vs. Inuit with values that are similar to those seen in Canadian Caucasian populations. Sex, age, waist circumference and systolic BP are major factors that increase the risk of this inflammatory phenotype among Inuit from Nunavik, despite their different lifestyle background compared with Caucasians.

    and physician-derived scores. Thirty out-clinic RA patients with stable disease were included. A joint count was performed two times 1 week apart by the patient and by an experienced physician. Test-retest reliability was expressed as the least significant difference (LSD), as the LSD in percent of the mean...... score (%LSD) and as intra-individual coefficients of variation (CVi). Mean scores based on physician vs. patient joint counts (visit 1) were: DAS28-CRP(4v) 3.5 ± 1.0 vs. 3.6 ± 1.1 (not significant (NS)), DAS28-CRP(3v) 3.4 ± 0.9 vs. 3.5 ± 0.9 (NS), SDAI 14.2 ± 9.4 vs.14.1 ± 9.4 (NS) and CDAI 13.4 ± 9.......3 vs. 13.3 ± 9.4 (NS). The LSDs (%LSD) for duplicate assessments of patient-derived scores (visit 2 vs. 1) were: DAS28-CRP(4v) 0.8 (23.2), DAS28-CRP(3v) 0.9 (25.2), SDAI 8.3 (59.9) and CDAI 8.4 (63.8). Similar LSDs were found for differences between duplicate assessments of physician-derived scores...

  1. CRP-Mediated Carbon Catabolite Regulation of Yersinia pestis Biofilm Formation Is Enhanced by the Carbon Storage Regulator Protein, CsrA.

    Full Text Available The natural transmission of Yersinia pestis is reliant upon biofilm blockage of the flea vector. However, the environmentally-responsive adaptive regulators which facilitate Y. pestis biofilm production in accordance with the flea midgut milieu are not well understood. We seek to establish the impact of available carbon source metabolism and storage upon Y. pestis biofilm production. Our findings demonstrate that Y. pestis biofilm production is subject to carbon catabolite regulation in which the presence of glucose impairs biofilm production; whereas, the sole metabolism of alternate carbon sources promotes robust biofilm formation. This observation is facilitated by the cAMP receptor protein, CRP. In accordance with a stark growth defect, deletion of crp in both CO92 and KIM6+ Y. pestis strains significantly impaired biofilm production when solely utilizing alternate carbon sources. Media supplementation with cAMP, a small-molecule activator of CRP, did not significantly alter Y. pestis biofilm production. Furthermore, CRP did not alter mRNA abundance of previously-characterized hms biofilm synthesis and regulation factors. Therefore, our findings indicate CRP does not confer a direct stimulatory effect, but may indirectly promote Y. pestis biofilm production by facilitating the alternate carbon source expression profile. Additionally, we assessed the impact of the carbon storage regulator protein, CsrA, upon Y. pestis biofilm production. Contrary to what has been described for E. coli, Y. pestis biofilm formation was found to be enhanced by CsrA. Regardless of media composition and available carbon source, deletion of csrA significantly impaired Y. pestis biofilm production. CsrA was found to promote Y. pestis biofilm production independent of glycogen regulation. Loss of csrA did not significantly alter relative hmsH, hmsP, or hmsT mRNA abundance. However, deletion of hmsP in the csrA-deficient mutant enabled excessive biofilm production

    Full Text Available BACKGROUND: Many studies have shown that obesity was closely related to insulin resistance via several pathways such as inflammation, oxidative stress, lipolysis, and endothelial dysfunction. This study was carried out to observe the correlation between inflammation (IL-6 and hsCRP, lipolysis process (ET-1, and endothelial dysfunction (ADMA and insulin resistance (HOMA-IR in centrally obese men. METHODS: This was a cross sectional study on 62 male subjects aged 30–60 years old with waist circumference (WC >90 cm. IL-6, ET-1 and ADMA levels were measured using ELISA method, while hsCRP and insulin were measured using chemiluminescence method. All blood testings were conducted in Prodia Clinical Laboratory. RESULTS: The results showed that WC was significantly correlated with hsCRP (r=0.294, p=0.022, ET-1 (r=0.257, p=0.047 and ADMA (r=0.338, p=0.009. We also found a significant correlation between hsCRP with HOMA-IR (r=0.324, p=0.021, ADMA with HOMA-IR (r=0.280, p=0.045 and IL-6 with hsCRP (r=0.437, p=0.003. CONCLUSIONS: hsCRP and ADMA have significant correlation with HOMA-IR in centrally obese men. HOMA-IR significantly increases in subjects with ADMA above median and either IL-6 or hsCRP above median, as compared to those in the other groups. Inflammation and endothelial dysfunction are important causal pathways of insulin resistance state in centrally obese men. KEYWORDS: obesity, IL-6, hsCRP, ET-1, ADMA, HOMA-IR.

    Full Text Available Abstract Background Despite the characteristic extensive tubulointerstitial fibrosis, Balkan Endemic Nephropathy (BEN is usually considered a non-inflammatory disease. Methods We examined a marker of inflammation, C-reactive protein (CRP, in the offspring of patients with BEN, a population at risk for BEN, prior to development of established disease to determine if an inflammatory process could be identified in the early stages of the disease. In 2003/04, 102 adult offspring whose parents had BEN and a control group of 99 adult offspring of non-BEN patients were enrolled in this prospective study. This cohort was re-examined yearly for four consecutive years. Levels of serum CRP were measured in years 3 and 4 and compared between groups. The data were analyzed with mixed models. Results Compared to controls, offspring of BEN parents had statistically higher CRP levels in two consecutive years, suggestive of early inflammatory reactivity. Whenever the mother was affected by BEN (both parents, or mother only, serum CRP was significantly increased, but not if only the father had BEN. CRP was inversely related to kidney cortex width but not to markers or renal function. Conclusion Early stages of BEN may involve inflammatory processes. The observation of a maternal involvement supports the concept of fetal programming, which has been implicated in the pathogenesis of other chronic kidney diseases.

    Full Text Available Objective: Modified Fenestration-Restorative Spinoplasty (MFRS technique is an alternative to lumbar stenosis treatment, providing the equal decompression comparing with laminectomy techniques, without the implant, less expensive and complication rates. The purpose of this study was to determine which technique gives better inflammation and clinical outcome based on high sensitive C-Reactive Protein biomarker (hsCRP and Prostaglandin E2 (PGE 2, Visual Analog Scale (VAS of the day 7th postsurgery and ODI scores 3rd month post surgery. Methods: This study design is an experimental pretest-posttest randomized control group design. Results: This study results showed that the mean levels of hsCRP day 7th postsurgery were differ significantly between MFRS (23,09 ± 15,3 mg/L compared to LF (39,53 ± 24,4 mg/L. Likewise for the mean levels of PGE2 day 7th postsurgery were differ significantly between MFRS (491,39 ± 528,5 pg/ml compared to LF (1103,7 ± 1033,6 pg/ml at the significance level of p <0.05. MFRS clinical outcomes better than LF (p <0.05, for means of VAS value day 7th postsurgery and ODI score 3rd month postsurgery. Perioperative variable analysis shows that MFRS was better than LF in: length of surgery, blood loss, postsurgery Hb and patient length of stay (p<0,05. Conclusions: MFRS technique is an alternative technique of lumbar stenosis treatment better than the LF, in terms of improved levels of hsCRP and PGE2, leading to faster clinical outcomes improvement, less complications and lower costs. MFRS technique should be used as a treatment of lumbar stenosis.

    Introduction Low plasma selenium concentrations are frequent in critically ill patients. However, whether this is due to systemic inflammation, a deficient nutritional state or both is still not clear. We aimed to determine the factors associated with low plasma selenium in critically ill children while considering the inflammatory response and nutritional status. Method A prospective study was conducted in 173 children (median age 34 months) with systemic inflammatory response who had plasma selenium concentrations assessed 48 hours after admission and on the 5th day of ICU stay. The normal reference range was 0.58 μmol/L to 1.6 μmol/L. The outcome variable was ‘low plasma selenium’, which was defined as plasma selenium values below the distribution median during this period. The main explanatory variables were age, malnutrition, sepsis, C-reactive protein (CRP), and clinical severity scores. The data were analyzed using a Binomial Generalized Estimating Equations model, which includes the correlation between admission and 5th day responses. Results Malnutrition and CRP were associated with low plasma selenium. The interaction effect between these two variables was significant. When CRP values were less than or equal to 40 mg/L, malnutrition was associated with low plasma selenium levels (odds ratio (OR) = 3.25, 95% confidence interval (CI) 1.39 to 7.63, P = 0.007; OR = 2.98, 95% CI 1.26 to 7.06, P = 0.013; OR = 2.49, 95% CI 1.01 to 6.17, P = 0.049, for CRP = 10, 20 and 40 mg/L, respectively). This effect decreased as CRP concentrations increased and there was loose significance when CRP values were >40 mg/L. Similarly, the effect of CRP on low plasma selenium was significant for well-nourished patients (OR = 1.13; 95% CI 1.06 to 1.22, P selenium. This interaction should be considered when interpreting plasma concentrations as an index of selenium status in patients with systemic inflammation as well as in the decision

    To evaluate the effects of perioperative oral administration of carprofen and meloxicam on concentrations of 3 acute-phase proteins in dogs undergoing elective ovariohysterectomy (OVH). 18 healthy adult anestrous female dogs undergoing elective OVH. Dogs were allocated to 3 groups (6 dogs/group). A placebo treatment, carprofen (2.0 mg/kg), or meloxicam (0.2 mg/kg) was orally administered to the dogs of the respective groups. The initial doses were administered 30 minutes before premedication prior to OVH; additional doses were administered once daily for 4 days after surgery. Blood samples were collected 45 minutes before premedication and 4, 8, 12, 24, 36, 48, 72, 96, and 120 hours after the end of OVH; samples were used for measurement of total WBC and neutrophil counts and concentrations of C-reactive protein (CRP), ceruloplasmin, and fibrinogen. Values did not differ significantly among groups for WBC and neutrophil counts, serum concentrations of CRP and ceruloplasmin, and plasma concentrations of fibrinogen. Concentrations of all inflammatory markers, except serum ceruloplasmin, increased significantly following OVH, but in a similar manner for each group. No significant changes were detected in serum ceruloplasmin concentrations over time. Perioperative administration of both carprofen and meloxicam did not significantly affect the concentrations of CRP, ceruloplasmin, and fibrinogen in dogs undergoing OVH. Thus, use of carprofen or meloxicam should not affect clinical interpretation of results for these 3 acute-phase proteins.

    Full Text Available We investigate whether ownership concentration influences bank profitability in a developing country context. We focus on bank ownership concentration measured as the amount of direct equity held by a majority shareholder categorised into: high ownership concentration, moderate ownership concentration and disperse ownership. We find that banks with high ownership concentration have higher return on assets, higher net interest margin and higher recurring earning power while banks with dispersed ownership have lower return on assets but have higher return on equity. Also, higher cost efficiency improves the return on assets of widely-held banks and the return on equity of banks with moderate ownership. The findings have implications.

    The latest IAEA Co-ordinated Research Project (CRP-8) focuses on the application of the Master Curve approach to monitor fracture toughness of reactor pressure vessels in nuclear power power plants. Three main work areas have been identified: (a) constraint and geometry effects on Master Curve To values; (b) loading rate effects up to impact conditions; (c) potential changes of Master Curve shape for highly embrittled materials. After the kick-off meeting in Vienna in October 2004, the first Research Coordination Meeting was held in May 2005, hosted by AEKI Budapest. The present document focuses on the participation and contribution of SCK-CEN to Topic Area no. 2 (Loading rate effects on Master Curve - Impact Loading), for which E. Lucon acts as co-task leader. A Round-Robin exercise is planned for early 2006, consisting in 10 tests per participant on precracked Charpy-V specimen of JRQ, tested dynamically using an instrumented pendulum; the results will be analysed using the Master Curve procedure (ASTM E1921-05) and compared to data obtained at other loading rates (quasi-static and/or dynamic). Guidelines and detailed specifications have been produced and circulated after the meeting in Budapest. SCK-CEN has also produced data reporting sheets in EXCEL97 form, which will be used for reporting all fracture toughness test results (at quasi-static, dynamic or impact loading rates) performed in the framework of the CRP-8.

    The radical change of lifestyle during Ramadan fast has shown to affect cardiometabolic risk variables in adults. In youth, however, no studies are available. We aimed to evaluate the effect of Ramadan fast on Body Mass Index (BMI) and the cardiometabolic profile of obese adolescents. A prospective cohort study was conducted. We measured weight, height, body composition, blood pressure, heart rate, glucose, insulin, total cholesterol, low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol, triglycerides, and high sensitivity C-reactive protein (hs-CRP) levels before, during the last week of and at 6 weeks after Ramadan. Twenty-five obese adolescents were included. BMI and glucose metabolism did not change after Ramadan or at 6 week after cessation of Ramadan. At the end of Ramadan, a significant decrease in body fat percentage was observed, while significant increases in heart rate, total cholesterol, LDL cholesterol, HDL cholesterol, and hs-CRP were found (all P < 0.05). Six weeks after Ramadan, all parameters returned to baseline levels. In this sample of 25 ethnic obese adolescents transient cardiometabolic changes were observed during Ramadan fasting. Since most of these changes were reversible within 6 weeks, there seems no harm or benefit for obese adolescents to participate in Ramadan.

    Serum amyloid A (SAA) and serum amyloid P (SAP) were detected in cultures of hepatocytes which had been isolated from normal CBA/J mice by the collagenase perfusion technique. SAP production in 24 h cultures was more resistant than SAA and total protein synthesis to inhibition by actinomycin D, but was more sensitive to inhibition by 48 h. However, the production of SAP was more sensitive to cycloheximide than SAA and total protein throughout the 48 hr incubation period. SAP and SAA levels in the culture media were suppressed by treatment of liver cells with 10 -6 M of colchicine for 48 h. Inhibition of SAP production by colchicine was the same regardless of culture condition, but the effect of colchicine on SAA synthesis varied according to the presence of serum of monokine. These observations also support the concept that the two amyloid proteins are produced under different regulatory mechanisms. When C-reactive protein (CRP) was not detected in the sera of patients with severe chronic liver diseases, the SAA levels were very low. When CRP was detected, SAA values were within the normal range. Thus, in order to produce SAA, liver cells in these patients not only were viable but also maintained their specialized function

    Even though transcriptional regulation plays a key role in establishing the metabolic network, the extent to which it actually controls the in vivo distribution of metabolic fluxes through different pathways is essentially unknown. Based on metabolism-wide quantification of intracellular fluxes, we systematically elucidated the relevance of global transcriptional regulation by ArcA, ArcB, Cra, Crp, Cya, Fnr, and Mlc for aerobic glucose catabolism in batch cultures of Escherichia coli. Knockouts of ArcB, Cra, Fnr, and Mlc were phenotypically silent, while deletion of the catabolite repression regulators Crp and Cya resulted in a pronounced slow-growth phenotype but had only a nonspecific effect on the actual flux distribution. Knockout of ArcA-dependent redox regulation, however, increased the aerobic tricarboxylic acid (TCA) cycle activity by over 60%. Like aerobic conditions, anaerobic derepression of TCA cycle enzymes in an ArcA mutant significantly increased the in vivo TCA flux when nitrate was present as an electron acceptor. The in vivo and in vitro data demonstrate that ArcA-dependent transcriptional regulation directly or indirectly controls TCA cycle flux in both aerobic and anaerobic glucose batch cultures of E. coli. This control goes well beyond the previously known ArcA-dependent regulation of the TCA cycle during microaerobiosis.

    Chronic low-grade inflammation may induce chronic kidney disease in patients with type 2 diabetes. This study investigated the relation between inflammatory biomarkers and chronic kidney disease in patients with type 2 diabetes, which has not yet been reported in Asian populations. A cross-sectional study was performed in 543 patients recruited from diabetic clinics for an ongoing, prospective study. Multivariate logistic regression was used to evaluate the association between inflammatory biomarkers and the presence of chronic kidney disease (estimated glomerular filtration rate Disease equation using plasma creatinine). The risk of chronic kidney disease increased in the highest quartiles of C-reactive protein (CRP) [multivariate odds ratio (OR) = 3.73; 95% CI = 1.19-1.70] and tumor necrosis factor-alpha (multivariate OR = 4.45; 95% CI = 1.63-12.11) compared to the lowest quartiles after adjustments for age, sex, zinc intake, and other putative risk factors for chronic kidney disease. Our results suggest that CRP and tumor necrosis factor-alpha may be independent risk factors for chronic kidney disease in patients with type 2 diabetes. A causal mechanism of this association should be evaluated in a followup study of Korean patients with type 2 diabetes.

    Ray tracing is the basis of the present analysis of truncated bifacial compound parabolic concentrators filled with a dielectric substance, which are of interest in photovoltaic applications where the bifacial cells allow higher static concentrations to be achieved. Among the figures of merit for this type of concentrator, the directional intercept factor plays a major role and is defined as the ratio of the power of the collector to that at the entry aperture, in a lossless concentrator illuminated by light arriving from a given direction. A procedure for measuring outdoor, full size panels has been developed, and a correction method for avoiding the effect of unwanted diffuse radiation during the measurements is presented.

    Full Text Available BACKGROUND: Obesity is highly related to insulin resistance, therefore, the increased number of obesity is followed by the increased prevalence of type 2 Diabetes Melitus. Obesity is associated with increased of reactive oxygen species (ROS in muscle, liver and endothelial cells. The increase of ROS would lead to insulin resistance (IR and increased pro-inflammatory protein. FFA plays an important role in IR by inhibiting muscle glucose transport and oxidation via effects on serine/threonine phosphorylation of IRS-1. The aim of this study was discover the existence of SOD, hs-CRP and and adiponectin levels towards the occurrence of insulin resistance which was caused by elevated level of FFA and to discover the interaction between SOD, hs-CRP and adiponectin in non diabetic obese adult male. METHODS: This was observational study with cross sectional design. There were 65 obese male non diabetic subjects and 45 non obese male non diabetic subjects who met the criteria. In this study, measurements were done on body mass index (BMI, fasting glucose, insulin, adiponectin, hs-CRP and SOD. Obese was defined as BMI >25 kg/m2, normal weight was defined as BMI 18.5-23 kh/m2 and Insulin Resistance was defined as HOMA-IR >1. RESULTS: This study showed that Hypoadiponectinemia condition, decreased SOD level and high level of hs-CRP is associated with insulin resistance in obese non diabetic subject. Adiponectin and SOD were correlated negatively with insulin resistance in obese non diabetic (Adiponectin, r=-0.455, p<0.001; SOD, r=-0.262, p=0.003, hs-CRP was positively correlated with insulin resistance in obese non diabetic (r=0.592, p<0.001.

    The lemon detox program is a very low-calorie diet which consists of a mixture of organic maple and palm syrups, and lemon juice for abstinence period of 7 days. We hypothesized that the lemon detox program would reduce body weight, body fat mass, thus lowering insulin resistance and known risk factors of cardiovascular disease. We investigated anthropometric indices, insulin sensitivity, levels of serum adipokines, and inflammatory markers in overweight Korean women before and after clinical intervention trial. Eighty-four premenopausal women were randomly divided into 3 groups: a control group without diet restriction (Normal-C), a pair-fed placebo diet group (Positive-C), and a lemon detox diet group (Lemon-D). The intervention period was 11 days total: 7 days with the lemon detox juice or the placebo juice, and then 4 days with transitioning food. Changes in body weight, body mass index, percentage body fat, and waist-hip ratio were significantly greater in the Lemon-D and Positive-C groups compared to the Normal-C group. Serum insulin level, homeostasis model assessment insulin resistance scores, leptin, and adiponectin levels decreased in the Lemon-D and Positive-C groups. Serum high-sensitive C-reactive protein (hs-CRP) levels were also reduced only in the Lemon-D group. Hemoglobin and hematocrit levels remained stable in the Lemon-D group while they decreased in the Positive-C and Normal-C groups. Therefore, we suppose that the lemon detox program reduces body fat and insulin resistance through caloric restriction and might have a potential beneficial effect on risk factors for cardiovascular disease related to circulating hs-CRP reduction without hematological changes.

    The critical roughage part (CRP) of 2 diet types was determined in a cross-over design with 6 double-muscled and 6 normally conformed Belgian Blue bulls fitted with rumen cannulae. The roughage:concentrate ratio was lowered weekly until signs of a lack of physical structure were observed. For diet 1, consisting of maize silage and concentrates, the initial proportion of maize silage was 25% of DM but it decreased weekly with 5% units of DM. For the second diet, consisting of wheat straw and concentrate, 12% straw (DM basis) was provided during the first week and thereafter the proportion of straw decreased weekly with 3% units of DM. Several directly observable parameters (rumen pH, feed intake, bloat, faecal consistency) were evaluated weekly for each bull. Apart from these direct indicators of acidosis, also other parameters, whose results were only available after the end of the trial, were determined (volatile fatty acid profile, lactic acid concentration, chewing time). The roughage part between the part fed when signs of a lack of physical structure was first observed and the part that was fed the week before, was considered as the CRP. Most animals showed no acute signs of clinical acidosis (directly observable parameters) and finished the trial on a 100% concentrate diet. However, in sacco rumen DM-degradabilities of maize silage, grass silage and wheat grain was depressed considerably when low roughage diets were fed. Based on all observed parameters, the mean CRP was calculated to be 14.7% for diet 1 and 8.1% for diet 2. The beef type (double-muscled or not) had no influence on the CRP.

    Background: Prenatal exposure to dietary protein may program growth-regulating hormones, consequently influencing early-life growth patterns and later risk of associated chronic diseases. The insulin-like growth factor (IGF) axis is of particular interest in this context given its influence on pre- and postnatal growth and its sensitivity to the early nutritional environment. Objective: Our objective was to examine associations of maternal protein intake during pregnancy with cord blood concentrations of IGF-I, IGF-II, IGF binding protein-3 (IGFBP-3), and insulin. Methods: We studied 938 mother-child pairs from early pregnancy through delivery in the Project Viva cohort. Using multivariable linear regression models adjusted for maternal race/ethnicity, education, income, smoking, parity, height, and gestational weight gain and for child sex, we examined associations of second-trimester maternal protein intake [grams per kilogram (weight before pregnancy) per day], as reported on a food frequency questionnaire, with IGF-I, IGF-II, IGFBP-3, and insulin concentrations in cord blood. We also examined how these associations may differ by child sex and parity. Results: Mothers were predominantly white (71%), college-educated (64%), and nonsmokers (67%). Mean ± SD protein intake was 1.35 ± 0.35 g ⋅ kg -1 ⋅ d -1 Each 1-SD increment in second-trimester protein intake corresponded to a change of -0.50 ng/mL (95% CI: -2.26, 1.26 ng/mL) in IGF-I and -0.91 μU/mL (95% CI: -1.45, -0.37 μU/mL) in insulin. Child sex and parity modified associations of maternal protein intake with IGF-II and IGFBP-3: protein intake was inversely associated with IGF-II in girls ( P -interaction = 0.04) and multiparous mothers ( P -interaction = 0.05), and with IGFBP-3 in multiparous mothers ( P -interaction = 0.04). Conclusions: In a cohort of pregnant women with relatively high mean protein intakes, higher intake was associated with lower concentrations of growth-promoting hormones in cord

    The Second Research Coordination Meeting for the Co-ordinated Research Project (CRP) on 'Ingestion and Organ Content of Trace Elements of Importance in Radiological Protection: Reference Asian Man Project, Phase 2' was held at the China Institute for Radiation Protection (CIRP) in Taiyuan, People's Republic of China. During the first technical Session, an overview of the current status of the CRP was presented by the IAEA technical officer, Dr. Parr, and the responsible officer of the Central Reference Laboratory (NIRS, Japan), Dr. Kawamura. They drew attention to the agreed programme of work, as described in the project documentation, and the timetable foreseen for the CRP as summarized in table 1. In general, they concluded that the achievements of the CRP to-date appear to be good, particularly in relation to sample collection (in most countries) and quality control (the development of appropriate reference materials). However, some aspects of the work appear to be a little behind schedule, particularly (1) the final stages of preparation of total diet samples (because of delays in providing a suitable food blender), (2) the analysis of some of the elements of first priority (because of the non-availability, until now, of suitable analytical reference materials), and (3) in some countries, the collection of autopsy specimens. One country (Malaysia) has experienced considerable difficulties in implementing the project due to the retirement of the former Chief Scientific Investigator. For this reason it was unfortunately not possible for the Malaysian representative to be present at the RCM

    The increase of ozone concentration in urban is one of the most important research topics on environmental science. With the increase of nitrogen oxides and hydrogen-carbon compounds which are exhausted from cars, the ozone concentration in urban is obviously increased on sunlight, and threat of photochemistry smog will be possible. Therefore, it is very important to monitor and study the ozone concentration distribution in urban. The frequency-distribution, diurnal variation and monthly variation of ozone concentration were studied on the campus of Shandong University during six months monitoring. The influence of solar radiation and weather conditions on ozone concentration were discussed. The frequency of ozone concentration less than 200 microg/m3 is 96.88%. The ozone concentration has an obvious diurnal variation. The ozone concentration in the afternoon is higher than in the morning and in the evening. The maximum appears in June, when it is the strong solar radiation and high air-temperature. The weather conditions also influence the ozone concentration. The ozone concentration in clear day is higher than in rainy and cloudy day.

    The knowledge on the level of systemic inflammation in peripheral artery disease (PAD) is less well established than that in coronary artery disease (CAD). Systemic inflammation frequently coincides with atherosclerosis, but also with various traits of the metabolic syndrome (MetS). The individual contribution of CAD, PAD, and the MetS to inflammation is not known. We enrolled a total of 1396 patients, 460 patients with PAD Fontaine stages IIa-IV verified by duplex ultrasound (PAD group) and 936 patients free of limb claudication undergoing coronary angiography, of whom 507 had significant CAD with coronary stenoses ≥50% (CAD group), and 429 did not have significant CAD at angiography (control group). C-reactive protein (CRP) was significantly higher in the PAD than in the CAD or in the control group (0.86 ± 1.85 mg/dl versus 0.44 ± 0.87 mg/dl and 0.39 ± 0.52 mg/dl, respectively, p < 0.001 for both comparisons). These significant differences were confirmed when patients with and subjects without the MetS were analyzed separately. In particular, within the PAD group, CRP was significantly higher in patients with the MetS than in subjects without the MetS (1.04 ± 2.01 vs. 0.67 ± 1.64 mg/dl; p = 0.001) and both, the presence of PAD and the MetS proved to be independently associated with CRP in analysis of covariance (F = 31.84; p < 0.001 and F = 10.52; p = 0.001, respectively). Inflammatory activity in PAD patients is higher than in CAD patients and is particularly high in PAD patients affected by the MetS. Low grade systemic inflammation is independently associated with both the MetS and PAD. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  12. Roles of a novel Crp/Fnr family transcription factor Lmo0753 in soil survival, biofilm production and surface attachment to fresh produce of Listeria monocytogenes.

    Directory of Open Access Journals (Sweden)

    Joelle K Salazar

    Full Text Available Listeria monocytogenes is a foodborne bacterial pathogen and the causative agent of an infectious disease, listeriosis. L. monocytogenes is ubiquitous in nature and has the ability to persist in food processing environments for extended periods of time by forming biofilms and resisting industrial sanitization. Human listeriosis outbreaks are commonly linked to contaminated dairy products, ready-to-eat meats, and in recent years, fresh produce such as lettuce and cantaloupes. We identified a putative Crp/Fnr family transcription factor Lmo0753 that is highly specific to human-associated genetic lineages of L. monocytogenes. Lmo0753 possesses two conserved functional domains similar to the major virulence regulator PrfA in L. monocytogenes. To determine if Lmo0753 is involved in environmental persistence-related mechanisms, we compared lmo0753 deletion mutants with respective wild type and complementation mutants of two fully sequenced L. monocytogenes genetic lineage II strains 10403S and EGDe for the relative ability of growth under different nutrient availability and temperatures, soil survival, biofilm productivity and attachment to select fresh produce surfaces including romaine lettuce leaves and cantaloupe rinds. Our results collectively suggested that Lmo0753 plays an important role in L. monocytogenes biofilm production and attachment to fresh produce, which may contribute to the environmental persistence and recent emergence of this pathogen in human listeriosis outbreaks linked to fresh produce.

    Shewanella species are a group of facultative Gram-negative microorganisms with remarkable respiration abilities that allow the use of a diverse array of terminal electron acceptors (EA). Like most bacteria, S. oneidensis possesses multiple terminal oxidases, including two heme-copper oxidases (caa3- and cbb3-type) and a bd-type quinol oxidase. As aerobic respiration is energetically favored, mechanisms underlying the fact that these microorganisms thrive in redox-stratified environments remain vastly unexplored. In this work, we discovered that the cbb3-type oxidase is the predominant system for respiration of oxygen (O2), especially when O2 is abundant. Under microaerobic conditions, the bd-type quinol oxidase has a significant role in addition to the cbb3-type oxidase. In contrast, multiple lines of evidence suggest that under test conditions the caa3-type oxidase, an analog to the mitochondrial enzyme, has no physiological significance, likely because of its extremely low expression. In addition, expression of both cbb3- and bd-type oxidases is under direct control of Crp (cAMP receptor protein) but not the well-established redox regulator Fnr (fumarate nitrate regulator) of canonical systems typified in Escherichia coli. These data, collectively, suggest that adaptation of S. oneidensis to redox-stratified environments is likely due to functional loss of the caa3-type oxidase and switch of the regulatory system for respiration.

    Full Text Available Abstract Background Soluble fibers lower serum lipids, but are difficult to incorporate into products acceptable to consumers. We investigated the physiological effects of a concentrated oat β-glucan on cardiovascular disease (CVD endpoints in human subjects. We also compared the fermentability of concentrated oat β-glucan with inulin and guar gum in a model intestinal fermentation system. Methods Seventy-five hypercholesterolemic men and women were randomly assigned to one of two treatments: 6 grams/day concentrated oat β-glucan or 6 grams/day dextrose (control. Fasting blood samples were collected at baseline, week 3, and week 6 and analyzed for total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, glucose, insulin, homocysteine and C-reactive protein (CRP. To estimate colonic fermentability, 0.5 g concentrated oat β-glucan was incubated in a batch model intestinal fermentation system, using human fecal inoculum to provide representative microflora. Fecal donors were not involved with the β-glucan feeding trial. Inulin and guar gum were also incubated in separate serum bottles for comparison. Results Oat β-glucan produced significant reduction from baseline in total cholesterol (-0.3 ± 0.1 mmol/L and LDL cholesterol (-0.3 ± 0.1 mmol/L, and the reduction in LDL cholesterol were significantly greater than in the control group (p = 0.03. Concentrated oat β-glucan was a fermentable fiber and produced total SCFA and acetate concentrations similar to inulin and guar gum. Concentrated oat β-glucan produced the highest concentrations of butyrate at 4, 8, and 12 hours. Conclusion Six grams concentrated oat β-glucan per day for six weeks significantly reduced total and LDL cholesterol in subjects with elevated cholesterol, and the LDL cholesterol reduction was greater than the change in the control group. Based on a model intestinal fermentation, this oat β-glucan was fermentable, producing higher amounts of butyrate than other

    This study aimed to compare concentrations of serum 25-hydroxy vitamin D and inflammatory markers in metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO), and to determine whether the relationship between vitamin D levels and both cardiometabolic and inflammatory markers differs between MHO and MUO. This cross-sectional study comprised 4391 obese subjects aged>18 years. A panel of cardiometabolic and inflammatory markers, including anthropometric variables, glycaemic indices, lipid profiles, liver enzymes, homocysteine, C-reactive protein (CRP), fibrinogen and serum 25-hydroxy vitamin D levels, was investigated. All cardiometabolic and inflammatory markers in MHO and MUO as well as in vitamin D deficiency were compared. Prevalence of MHO was 41.9% in our obese subjects using International Diabetes Federation criteria. Considering insulin resistance and inflammation, the prevalence of MHO was 38.4%. Individuals with MHO had significantly higher vitamin D concentrations compared with MUO, and this difference in vitamin D status persisted after accounting for BMI and waist circumference. Subjects with MHO had significantly better metabolic status, lower liver enzymes, lower inflammatory markers and higher serum 25-hydroxy vitamin D than those with MUO. Associations between vitamin D levels and inflammatory and cardiometabolic markers differed according to MHO/MUO status. Among MUO subjects, vitamin D deficiency was associated with higher liver marker and homocysteine levels. Serum vitamin D was negatively associated with fasting plasma glucose and HbA1c in MHO only. Serum 25-hydroxy vitamin D levels were lower in MUO vs MHO, and reduced vitamin D concentrations were more strongly associated with cardiometabolic and inflammatory markers in MUO than in MHO subjects. These findings suggest that a deficiency in vitamin D could be a key component of MUO. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    2015-01-01

    Background/Objectives Inflammation and oxidative stress are central in many disease states. The major anti-oxidative enzymes contain selenium. The selenium intake in Europe is low, and supplementation with selenium and coenzyme Q10, important anti-oxidants, was evaluated in a previous study. The aim of this study was to evaluate response on the inflammatory biomarkers C-reactive protein, and sP-selectin, and their possible impact on cardiovascular mortality. Subjects/Methods 437 elderly individuals were included in the study. Clinical examination, echocardiography, electrocardiography and blood samples were drawn. The intervention time was 48 months, and median follow-up was 5.2 years. The effects on inflammation/atherosclerosis were evaluated through analyses of CRP and sP-selectin. Evaluations of the effect of the intervention was performed using repeated measures of variance. All mortality was registered, and endpoints of mortality were assessed by Kaplan-Meier plots. Results The placebo group showed a CRP level of 4.8 ng/mL at the start, and 5.1 ng/mL at the study end. The active supplementation group showed a CRP level of 4.1 ng/mL at the start, and 2.1 ng/mL at the study end. SP-selectin exhibited a level of 56.6 mg/mL at the start in the placebo group and 72.3 mg/mL at the study end, and in the active group the corresponding figures were 55.9 mg/mL and 58.0 mg/mL. A significantly smaller increase was demonstrated through repeated measurements of the two biomarkers in those on active supplementation. Active supplementation showed an effect on the CRP and sP-selectin levels, irrespective of the biomarker levels. Reduced cardiovascular mortality was demonstrated in both those with high and low levels of CRP and sP-selectin in the active supplementation group. Conclusion CRP and sP-selectin showed significant changes reflecting effects on inflammation and atherosclerosis in those given selenium and coenzyme Q10 combined.

    2016-02-01

    We compared the effects of a eucaloric moderate-fat diet (18% protein, 36% fat, and 46% carbohydrate), a eucaloric low-fat high-carbohydrate diet (18% protein, 18% fat, and 64% carbohydrate), and a low-calorie (33% reduced) low-fat high-carbohydrate diet on biomarkers of systemic inflammation. We randomly assigned 102 participants (age 21-76 years and BMI 19.2-35.5 kg/m(2)) to the three different diets for 6 weeks in a parallel design intervention trial. All foods were provided. Ninety-three participants completed all study procedures; 92 were included in the analyses. Endpoints included plasma C-reactive protein (CRP), interleukin-6 (IL-6), soluble tumor necrosis factor receptors I and II (sTNFRI and II), and adiponectin. In the unadjusted primary analyses, none of the endpoints were differentially affected by the dietary interventions despite the significantly greater reductions in body weight and fat mass in participants consuming the low-calorie low-fat diet compared to the eucaloric diets (p loss (time × weight change interaction, p = 0.051). Adjusted for weight change, adiponectin was reduced in the groups consuming the low-fat diets relative to the moderate-fat diet (p = 0.008). No effect of the intervention diets or weight loss on CRP, IL-6, or sTNFRI and II was seen in these secondary analyses. In relatively healthy adults, moderate weight loss had minimal effects on systemic inflammation, and raised plasma adiponectin only modestly. A lower dietary fat and higher carbohydrate content had little impact on measures of systemic inflammation, but reduced adiponectin concentrations compared to a moderate-fat diet. The latter may be of concern given the consistent and strong inverse association of plasma adiponectin with many chronic diseases.

    2017-01-01

    Full Text Available We conducted this systematic review and meta-analysis of prospective studies to determine the effect of probiotic administration on serum C-reactive protein (CRP concentrations. We searched PubMed-Medline, Web of Science, the Cochrane, and Google Scholar databases (until May 2016 to identify prospective studies evaluating the impact of probiotic administration on CRP. We used a random effects models and generic inverse variance methods to synthesize quantitative data, followed by a leave-one-out method for sensitivity analysis. The systematic review registration number was: CRD42016039457. From a total of 425 entries identified via searches, 20 studies were included in the final analysis. The meta-analysis indicated a significant reduction in serum CRP following probiotic administration with a weighted mean difference (WMD of −1.35 mg/L, (95% confidence interval (CI −2.15 to −0.55, I2 65.1%. The WMDs for interleukin 10 (IL10 was −1.65 pg/dL, (95% CI −3.45 to 0.14, I2 3.1%, and −0.45 pg/mL, (95% CI −1.38 to 0.48, I2 10.2% for tumor necrosis factor alpha (TNF-α. These findings were robust in sensitivity analyses. This meta-analysis suggests that probiotic administration may significantly reduce serum CRP while having no significant effect on serum IL10 and TNF-α.

    2016-06-01

    Full Text Available Background: Different measures of body fat composition may vary in their relations to parameters of chronic inflammation. Methods: We assessed the relations of visceral (VAT and subcutaneous adipose tissue (SAT, BMI, and waist circumference (WC to serum concentrations of high-sensitive C-reactive protein (hs-CRP, tumor necrosis factor alpha (TNF-α, interleukin-6 (IL-6, resistin, and adiponectin in 97 healthy adults using multivariate linear regression models, adjusted for age, sex, smoking, physical activity, menopausal status, and use of aspirin or non-steroidal anti-inflammatory drugs (NSAIDs. Parameters of chronic inflammation were mutually adjusted. Results: VAT (β = 0.34, SAT (β = 0.43, BMI (β = 0.40, and WC (β = 0.47 were all significantly associated with hs-CRP. BMI was additionally inversely related to adiponectin (β = -0.29. In exploratory subgroup analyses defined by gender, BMI, smoking, and use of aspirin or NSAIDs, VAT was the strongest indicator for increased levels of IL-6, SAT was the most consistent indicator for increased levels of hs-CRP, and BMI was the most consistent indicator for decreased levels of adiponectin. WC showed to be a weak indicator for increased levels of hs-CRP and decreased levels of adiponectin. Conclusion: VAT, SAT, BMI, and WC show distinct associations with parameters of chronic inflammation. Whether these differences reflect differential metabolic risks requires clarification by longitudinal studies.

Terefore, this study was carried out with the aim of investigating the effect of 4 weeks of flaxseed extract supplementation on serum concentrations of Brain-derived neurotrophic factor (BDNF and C-reactive protein (CRP. Methods: In this double-blind study, 24 male students (mean age, 23.21±1.98 were randomly divided into two groups, including flaxseed extract (n=12 and placebo (n=12. After 4 weeks of supplementation with flaxseed extract, serum levels of BDNF and CRP was measured in fasting state. BDNF level was measured using an enzyme-linked immunosorbent assay (ELISA kit, and CRP level was measured using an immunoturbidimetric assay kit. Data were analyzed using t-test. The level of significance was set at p<0.05. Results: After four weeks of supplementation with flaxseed extract the mean serum level of BDNF significantly increased (p<0.001, but no significant change was observed in the serum level of CRP (p<0.591. Conclusion: It seems that supplementation with flaxseed extract through increasing BDNF level is useful for the improvement of cognitive and functional benefits of the brain.

  14. Fuel Class Higher Alcohols

    KAUST Repository

    Sarathy, Mani

    2016-08-17

    This chapter focuses on the production and combustion of alcohol fuels with four or more carbon atoms, which we classify as higher alcohols. It assesses the feasibility of utilizing various C4-C8 alcohols as fuels for internal combustion engines. Utilizing higher-molecular-weight alcohols as fuels requires careful analysis of their fuel properties. ASTM standards provide fuel property requirements for spark-ignition (SI) and compression-ignition (CI) engines such as the stability, lubricity, viscosity, and cold filter plugging point (CFPP) properties of blends of higher alcohols. Important combustion properties that are studied include laminar and turbulent flame speeds, flame blowout/extinction limits, ignition delay under various mixing conditions, and gas-phase and particulate emissions. The chapter focuses on the combustion of higher alcohols in reciprocating SI and CI engines and discusses higher alcohol performance in SI and CI engines. Finally, the chapter identifies the sources, production pathways, and technologies currently being pursued for production of some fuels, including n-butanol, iso-butanol, and n-octanol.

  15. Higher spin gauge theories

    Henneaux, Marc; Vasiliev, Mikhail A

    2017-01-01

    Symmetries play a fundamental role in physics. Non-Abelian gauge symmetries are the symmetries behind theories for massless spin-1 particles, while the reparametrization symmetry is behind Einstein's gravity theory for massless spin-2 particles. In supersymmetric theories these particles can be connected also to massless fermionic particles. Does Nature stop at spin-2 or can there also be massless higher spin theories. In the past strong indications have been given that such theories do not exist. However, in recent times ways to evade those constraints have been found and higher spin gauge theories have been constructed. With the advent of the AdS/CFT duality correspondence even stronger indications have been given that higher spin gauge theories play an important role in fundamental physics. All these issues were discussed at an international workshop in Singapore in November 2015 where the leading scientists in the field participated. This volume presents an up-to-date, detailed overview of the theories i...

    Full Text Available Internationalization of higher education is one of the key trends of development. There are several approaches on how to achieve competitiveness and performance in higher education and international academic mobility; students’ exchange programs, partnerships are some of the aspects that can play a significant role in this process. This paper wants to point out the student’s perception regarding two main directions: one about the master students’ expectation regarding how an internationalized master should be organized and should function, and second the degree of satisfaction of the beneficiaries of internationalized master programs from Babe-Bolyai University. This article is based on an empirical qualitative research that was implemented to students of an internationalized master from the Faculty of Economics and Business Administration. This research can be considered a useful example for those preoccupied to increase the quality of higher education and conclusions drawn have relevance both theoretically and especially practically.

    Yani Lina

    2009-12-01

    Full Text Available BACKGROUND: Fibroblast growth factor-21 (FGF21 is known as an important endocrine and paracrine regulator of metabolic homeostasis. Recent studies have shown that FGF21 attenuates lipolysis in human adipocytes, which is suggested as a FGF21's mechanism as anti-hyperlipidemia, anti-hyperglycemia and anti-obesity. The aim of this study was to measure the correlation between FGF21, FFA, hsCRP and HOMA-IR among Indonesian obese non diabetic males. METHODS: The study was observational with cross sectional design. The analysis was done in 137 subjects aged 30-60 years with non diabetic abdominal obesity. We measured the biochemical markers FGF21, FFA, hsCRP, fasting insulin and fasting glucose. We also measured weight, height, waist circumrefence (WC, creatinine, serum glutamin oxaloacetic transaminase (SGOT, and serum glutamic pyruvic transaminase (SGPT, systolic blood pressure (SBP and diastolic blood pressure (DBP. Correlation between markers was measured using Pearson and Spearman's analysis. RESULTS: There were significant positive correlations between FGF21-HOMA-IR (r=0.314, p=0.000; FGF21-WC (r=0.173, p=0.043; FFA=hsCRP r=0.270, p=0.001; and WC-HOMA-IR (r=0.279, p=0.001. There was significant negative correlation between FGF21-FFA (r=-0.038, p=0.657 and FGF21-hsCRP (r=-0.061, p=0.482. CONCLUSIONS: In this study we found that although there was no significant correlation, FGF21 might act as an anti-lipolytic and anti-inflammation agent among Indonesian obese non-diabetic males. Our findings agree with results of previous studies that the positive correlation between FGF21-WC and FGF21-HOMA-IR might occur as a compensatory mechanism or resistance to FGF21 in obesity.

Nowadays, the competitiveness of higher education institutions has become more and more appreciated in the national economy. In recent years, the frameworks of operation of higher education systems have gone through a total transformation. The number of applying students is continuously decreasing in some European countries therefore only those institutions can “survive” this shortfall, which are able to minimize the loss of the number of students. In this process, the factors forming the competitiveness of these budgetary institutions play an important role from the point of view of survival. The more competitive a higher education institution is, the greater the chance is that the students would like to continue their studies there and thus this institution will have a greater chance for the survival in the future, compared to ones lagging behind in the competition. Aim of our treatise prepared is to present the current situation and main data of the EU higher education and we examine the performance of higher education: to what extent it fulfils the strategy for smart, sustainable and inclusive growth which is worded in the framework of Europe 2020 programme. The treatise is based on analysis of statistical data.

    The general views on radiosensitivity of higher plants have been introduced from published references. The radiosensitivity varies with species, varieties and organs or tissues. The main factors of determining the radiosensitivity in different species are nucleus volume, chromosome volume, DNA content and endogenous compounds. The self-repair ability of DNA damage and chemical group of biological molecules, such as -SH thiohydroxy of proteins, are main factors to determine the radiosensitivity in different varieties. The moisture, oxygen, temperature radiosensitizer and protector are important external factors for radiosensitivity. Both the multiple target model and Chadwick-Leenhouts model are ideal mathematical models for describing the radiosensitivity of higher plants and the latter has more clear significance in biology

    A common single nucleotide polymorphism (SNP) in the gene of brain-derived neurotrophic factor (BDNF) results from a substitution at position 66 from valine (Val) to methionine (Met) and may predispose to human neuropsychiatric disorders. We proposed to determine whether these BDNF gene SNPs were associated with fibromyalgia syndrome (FMS) and/or any of its typical phenotypes. Patients with FMS (N = 95) and healthy normal controls (HNC, N = 58) were studied. Serum high-sensitivity C-reactive protein (hsCRP) levels were measured using an enzyme-linked immunosorbent assay (ELISA). The BDNF SNPs were determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).The BDNF SNP distribution was 65 (68%) Val/Val, 28 (30%) Val/Met, and 2 (2%) Met/Met for FMS and 40 (69%), 17(29%), and 1 (2%) for HNC, respectively. The serum high-sensitivity C-reactive protein (hsCRP)and body mass index (BMI) in FMS were higher than in HNC. The FMS with BDNF Val66Val had significantly higher mean BMI (P = 0.0001) and hsCRP (P = 0.02) than did FMS carrying the Val66Met genotype. This pattern was not found in HNC. Phenotypic measures of subjective pain, pain threshold, depression, or insomnia did not relate to either of the BDNF SNPs in FMS. The relative distribution BDNF SNPs did not differ between FMS and HNC. The BDNF Val66Met polymorphism is not selective for FMS. The BDNF Val66Val SNP identifies a subgroup of FMS with elevated hsCRP and higher BMI. This is the first study to associate a BDNF polymorphism with a FMS subgroup phenotype.

Results are expressed as means ± SEM. All significance and power testing on results was done at a level of alpha = 0.05. Area under the concentration time curve (AUC was calculated using the trapezoidal rule. One-way analysis of variance (ANOVA-1 was done between CGs, between TGs and between time points. One-way repeated measures analysis of variance (ANOVA-1-RM was done to compare CGs and TGs. Two-way analysis of variance (ANOVA-2 was performed on total serum amino acid (TSAA levels, urine N2 levels and CRP levels between each CG and TG. Results After baseline subtraction the mean AUC was significantly (p ≤ 0.05 greater in each TG compared the corresponding CG. Comparison of the mean AUC between each TG and each CG was not significantly different. Total serum amino acid (TSAA levels were significantly greater in each TG compared the corresponding CG. They were also significantly different between each TG but not between each CG. All individual serum amino acid (ISAA levels in TG-A2.5 except glycine, histidine, methionine and serine were significantly higher than in CG-A2.5 at 4 hr. All ISAA levels in TG-A5 except methionine and serine were significantly higher than in CG-A5 at 4 hr. The N2 balance was significantly higher in each TG compared to the corresponding CG, but not significantly different between each CG and between each TG. Significant differences in CRP levels are reported between each TG compared to the corresponding CG, but not significantly different between each TG and between each CG. Conclusion A patented blend of digestive proteases (Aminogen® increased the absorption rate of processed WPC over controls, as measured by statistically significant increases in AUC, TSAA levels, ISAA levels and N2 balance. Significant decreases in CRP levels and fluxes in AA levels are also

  1. Report of the second research co-ordination meeting of the CRP on development of kits for radioimmunometric assays for tumour markers

    A Co-ordinated Research Programme (CRP) on 'Development of Kits for Immunoradiometric Assays for tumour markers' was started towards the end of 1997. Ten laboratories from different parts of the world with experience in development of immunoassays are participating in this project and the first Research Co-ordination Meeting (RCM) was held at the Agency Head Quarters in Vienna during 3-7 December, 1997. Based on the discussions and recommendations made during this meeting, the participants have carried out the project work at their laboratories during the past 18 months. During this period two consignments (November 98 and March 99) of some of the essential reagents, namely the capture Mab (Mab 66; 5 mg), tracer Mabs (Mab 10; 0.5 mg for total PSA and Mab 30; 0.5 mg for free PSA assay) and PSA antigen (1.3 mg, 80% pure) were shipped to each participant to enable them to develop the assays and to assess their own in-house reagents. The second RCM was held at the University of Alberta, Edmonton, Canada, to review the results obtained thus far and to discuss the actions to be taken in the next phase of the project. All the participants presented the work done at their respective laboratories and discussed the results obtained. On the whole, it was observed that significant progress has been achieved by all the participants. In the area of production of monoclonal antibodies, significant accomplishment was achieved by Cuba, China and India. All the three laboratories had produced monoclonal antibodies against PSA and had been successful to various extents. Cuba could identify specific antibodies that could be used as capture antibody as well as tracer antibodies for free and total PSA assays. Small aliquots of these were brought and distributed to the participants for individual evaluation. China has also identified the monoclonals for an IRMA for total PSA while India had identified a monoclonal that could be used for coating. The selected antibodies have compared very

    Full Text Available Aims. To investigate the association of C-reactive protein (CRP and gamma glutamyltransferase (GGT concentrations with newly diagnosed diabetes defined by either glucose or HbA1c criteria in Chinese adults. Methods. A population-based cross-sectional study was conducted in 2006. Data from 1167 men and 1607 women aged 35–74 years were analyzed. Diabetes was defined according to either glucose or HbA1c criteria alone. Results. Compared with nondiabetes, multivariate-adjusted OR (95%CI was 1.13 (0.90,1.42 in men and 1.21 (1.00,1.45 in women for CRP and 1.42 (1.18,1.72 and 1.57 (1.31,1.87 for GGT, respectively. Neither CRP nor GGT was associated with the presence of diabetes defined by the HbA1c criterion. Conclusions. The effect of elevated CRP on diabetes defined by the glucose criterion was mediated through obesity, but elevated GGT was an independent risk factor for diabetes in this Chinese population. None of the two was, however, associated with the elevated HbA1c concentrations.

    The aim of this systematic review and meta-analysis of prospective interventional studies was to investigate the effects of coenzyme Q10 (CQ10) on plasma C-reactive protein (CRP) levels. PubMed/Medline, Web of Science (WoS), Cochrane Database and Google Scholar databases were searched (up to December 2016) to identify prospective studies evaluating the impact of CQ10 supplementation on CRP. Random effects models meta-analysis was used for quantitative data synthesis. Sensitivity analysis used the leave-one-out method, and heterogeneity was quantitatively assessed using the I 2 index. Systematic review PROSPERO database registration: CRD42016038155. From a total of 119 entries identified via searches, 7 studies were finally included to the analysis. The results of the meta-analysis indicated a non-significant reduction in CRP concentrations following supplementation with CQ10 with a weighted mean difference [WMD] of -0.25mg/l (95% confidence intervals [CI] -0.56 to 0.06, I 2 =42.0%). The WMD for the effects on interleukin 6 (IL6) was -0.72pg/dl, (95% CI -1.24 to -0.24, I 2 =51.8%). These findings were robust in sensitivity analyses. Random-effects meta-regression revealed that changes in plasma CRP levels were independent of the dosage of CQ10 (slope: -0.0005; 95% CI: -0.005, 0.004; p=0.832) while duration of supplementation was the dependent mediator (slope: slope: -0.111; 95% CI: -0.21, -0.004; p=0.042). In conclusion, CQ10 supplementation has a borderline favourable effect on CRP levels, and a significant effect on IL-6 level. This suggests that CQ10 supplementation likely attenuates subclinical inflammation. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The effect of lipoprotein apheresis (Direct Adsorption of Lipids, DALI) (LA) on plasma levels of pentraxin 3 (PTX3), an inflammatory marker that reflects coronary plaque vulnerability, and expression of PTX3 mRNA was evaluated in patients with hyperLp(a)lipoproteinemia and angiographically defined atherosclerosis/coronary artery disease. Eleven patients, aged 55 ± 9.3 years (mean ± SD), were enrolled in the study. PTX3 soluble protein levels in plasma were unchanged by 2 sessions of LA; however, a downregulation of mRNA expression for PTX3 was observed, starting with the first session of LA (p < 0.001). The observed reduction was progressively increased in the interval between the first and second LA sessions to achieve a maximum decrease by the end of the second session. A statistically significantly greater treatment-effect correlation was observed in patients undergoing weekly treatments, compared with those undergoing treatment every 15 days. A progressive reduction in plasma levels of C-reactive protein was also seen from the first session of LA, with a statistically significant linear correlation for treatment-effect in the change in plasma levels of this established inflammatory marker (R 2 = 0.99; p < 0.001). Our findings suggest that LA has anti-inflammatory and endothelium protective effects beyond its well-established efficacy in lowering apoB100-containing lipoproteins. PMID:26903710

    In this report the available information from the literature on chemical erosion and weathering rates in Finland and northern Sweden is reviewed and experimental data from recent followup studies in defined catchments is discussed. In glaciated terrain as in Finland the best estimates of chemical erosion rates are obtained when geochemical data of glacial till is used. Elemental fluxes in free-flowing rivers and river-lake systems have been studied in greater detail only in a few case studies. The Kalix river drainage basin investigations gave evidence that the mobilization of rare earth elements (REE) is determined by weathering processes in the upper till layers and that the C-horizon below about 0.75 m depth or generally below the groundwater table is practically unaffected by weathering. Also the removal of U from the watershed was found to happen mostly by groundwater flow through predominantly shallow aquifers. Another type of case study is constrained to regions where certain phenomena cause enhanced trace metal mobilization, as in a region stretched along the western coast of Finland where land-uplift exposes clay sediments rich in sulphides above the groundwater level, with the consequence of increased mobilization of a number of heavy metals. Very little quantitative information on elemental flux balances is available from river-lake systems. Some modelling has been attempted on one great lake system the lake Paeijaenne by use of fall-out nuclides. From the same lake a detailed record of sedimentation rates covering the whole period from the end of the latest glaciation to present is available and erosion rate variations since the end of the latest glaciation can be assessed. The main part of this study focusses on investigations of well-defined small catchments over a longer time period, where groundwater is discharging in springs. Geochemical fluxes worth mentioning seem to be constrained to the surficial geological layers which include overburden and the most fractured uppermost layers of bedrock. Influences of fluxes which might bring substances from greater depth cannot be distinguished in these catchments. Groundwater erosion rates are given for As, Cu, K, Rb, Th, U and Rn and compared with estimated till erosion rates. Estimates of heavy metal weathering rates (maps for Cu and U) based on base metal weathering rates for Finnish forest soils are given for most of the country except Lappland. The estimated mean weathering rate for Cu (0.21 mg/m 2 a; max. 1.96 mg/m 2 a) is consistent with river loads measured in western Finland, but not in the industrialized Helsinki region. Similar comparison studies are not available for Rb (1.2 mg/m 2 a), Th (0.17 mg/m 2 a) and U (0.054 mg/m 2 a) weathering rates. Natural fluxes of Cu and U from Finnish headwater streams during one summer period from 30 basins of about 30 km 2 drainage area are given. The estimated fluxes of Cu in 30 Finnish streams were 0.44 - 1418 g/month (mean 253 g/month). The estimated fluxes of U were 0.08 - 285 g/month (mean 41.2 g/month). A comparison of the measured headwater stream fluxes with estimated soil erosion rates shows consistency within the order of magnitude. (orig.)

    This article is the October 1994 uranium market summary. During this reporting period, volume on the spot concentrates market doubled. Twelve deals took place: three in the spot concentrates market, one in the medium and long-term market, four in the conversion market, and four in the enrichment market. The restricted price range widened due to higher prices at the top end of the range, while the unrestricted price range widened because of lower prices at the bottom end. Spot conversion prices were higher, and enrichment prices were unchanged

    Over the past 2 weeks, commissioning of the machine protection system has advanced significantly, opening up the possibility of higher intensity collisions at 3.5 TeV. The intensity has been increased from 2 bunches of 1010 protons to 6 bunches of 2x1010 protons. Luminosities of 6x1028 cm-2s-1 have been achieved at the start of fills, a factor of 60 higher than those provided for the first collisions on 30 March.   The recent increase in LHC luminosity as recorded by the experiments. (Graph courtesy of the experiments and M. Ferro-Luzzi) To increase the luminosity further, the commissioning crews are now trying to push up the intensity of the individual proton bunches. After the successful injection of nominal intensity bunches containing 1.1x1011 protons, collisions were subsequently achieved at 450 GeV with these intensities. However, half-way through the first ramping of these nominal intensity bunches to 3.5 TeV on 15 May, a beam instability was observed, leading to partial beam loss...

    1998-11-01

    Undergraduate physics programmes for the 21st century were under discussion at a recent event held in Arlington, USA, open to two or three members of the physics faculties of universities from across the whole country. The conference was organized by the American Association of Physics Teachers with co-sponsorship from the American Institute of Physics, the American Physical Society and Project Kaleidoscope. Among the various aims were to learn about physics departments that have successfully revitalized their undergraduate physics programmes with innovative introductory physics courses and multi-track majors programmes. Engineers and life scientists were to be asked directly how physics programmes can better serve their students, and business leaders would be speaking on how physics departments can help to prepare their students for the diverse careers that they will eventually follow. It was planned to highlight ways that departments could fulfil their responsibilities towards trainee teachers, to identify the resources needed for revitalizing a department's programme, and to develop guidelines and recommendations for a funding programme to support collaborative efforts among physics departments for carrying out the enhancements required. More details about the conference can be found on the AAPT website (see http://www.aapt.org/programs/rupc.html). Meanwhile the UK's Higher Education Funding Council has proposed a two-pronged approach to the promotion of high quality teaching and learning, as well as widening participation in higher education from 1999-2000. A total of £60m should be available to support these initiatives by the year 2001-2002. As part of this scheme the Council will invite bids from institutions to support individual academics in enhancing learning and teaching, as well as in recognition of individual excellence. As with research grants, such awards would enable staff to pursue activities such as the development of teaching materials

    The goal of the study was to examine the association of subcutaneous and visceral fat mass with serum concentrations of adipokines in 130 subjects with type 2 diabetes mellitus. The levels of serum high sensitivity C-reactive protein (HS-CRP), adiponectin, high-molecular-weight (HMW) adiponectin, interleukin-18, and retinol-binding protein 4 were measured. Percentage body fat was determined by dual energy X-ray absorptiometry, and subcutaneous and visceral fat areas were measured by abdominal CT. HS-CRP had significant positive correlations with percentage body fat and subcutaneous fat area, and a particularly significant positive correlation with visceral fat area. Serum adiponectin had a negative correlation with the subcutaneous and visceral fat areas, with the strongest correlation with the visceral fat area. Similar results were obtained for HMW adiponectin. Serum adiponectin had a negative correlation with visceral fat area in subjects with a visceral fat area 2 , but not in those with a visceral fat area ≥100 cm 2 . In contrast, serum HS-CRP showed a positive correlation with visceral fat area in subjects with visceral fat area ≥100 cm 2 , but not in those with a visceral fat area 2 . These findings indicate that an increased visceral fat area is associated with inflammatory changes, and that inflammatory reactions may alter the functional properties of visceral fat in type 2 diabetes mellitus.
