    The aim of this study was to assess the distribution of CT dose index (CTDI) values reported by sites undergoing ACR CT accreditation between 2002 and 2004. Weighted CTDI (CTDI(w)) values were measured and reported by sites applying for ACR CT accreditation, and the percentage of scanners with values above the 2002 ACR diagnostic reference levels (DRLs) was determined. Acquisition parameters for a site's adult head, adult abdominal, and pediatric abdominal examinations were used to calculate volume CTDI (CTDI(vol)), and the average and standard deviation were calculated by year. Histogram analysis was performed to determine 75th and 90th percentiles of CTDI(vol). Between September 2002 and December 2004, 829 scanners underwent the accreditation process. Volume CTDI values (average ± SD) for 2002, 2003, 2004, and 2002 to 2004, respectively, were 66.7 ± 23.5, 58.5 ± 17.5, 55.8 ± 15.7, and 59.1 ± 18.6 mGy for adult head examinations; 18.7 ± 8.0, 19.2 ± 8.6, 17.0 ± 7.6, and 18.4 ± 8.3 for adult abdominal examinations; and 17.2 ± 9.7, 15.9 ± 8.6, 14.0 ± 7.0, and 15.5 ± 8.4 for pediatric abdominal examinations. For 2004 data, 23.8%, 2.3%, and 6.9% of sites reported doses above the 2002 CTDI(w) reference levels, compared with 49.6%, 4.7%, and 15% for 2002 data for adult head, adult abdominal, and pediatric abdominal examinations, respectively. Seventy-fifth percentiles of CTDI(vol) were 76.8 mGy (adult head, 2002 only), 22.2 mGy (adult abdominal), and 20.0 mGy (pediatric abdominal). From 2002 to 2004, average CTDI(vol) values decreased by 10.9, 1.7, and 3.2 mGy for adult head, adult abdominal, and pediatric abdominal examinations. Effective January 1, 2008, the ACR program implemented United States-specific diagnostic reference levels of 75, 25, and 20 mGy, respectively, for the CTDI(vol) of routine adult head, adult abdominal, and pediatric abdominal CT scans.

    In IAEA CRP on `Heat Transport and Afterheat Removal for GCRs under Accident Conditions`, experimental data of the JAERI`s cooling panel test apparatus were selected as benchmark problems to verify the validity of computational codes for design and evaluation of the performance of heat transfer and temperature distribution of components in the cooling panel system of the HTGR. The test apparatus was composed of a pressure vessel (P.V) with 1m in diameter and 3m in height, containing heaters with the maximum heating rate of 100kW simulating decay heat, cooling panels surrounding the P.V and the reactor cavity occupied by air at the atmospheric pressure. Seven experimental data were established as benchmark problems to evaluate the effect of natural convection of superheated gas on temperature distribution of the P.V and the performance of heat transfer of both the water and the air cooling panel systems. The analytical code THANPACST2 was applied to analyze two benchmark problems to verify the validity of the analytical methods and models proposed. Under the conditions at helium gas pressure of 0.73MPa and temperature of 210degC in the P.V of the water cooling panel system, temperatures of the P.V were well estimated within the errors of -14% to +27% compared with the experimental data. The analyses indicated that the heat transferred to the cooling panel was 11.4% less than the experimental value and the heat transferred by thermal radiation was 74.4% of the total heat input.

  9. Conservation Reserve Program (CRP) contributions to wildlife habitat, management issues, challenges and policy choices--an annotated bibliography

    Science.gov (United States)

    Allen, Arthur W.; Vandever, Mark W.

    2012-01-01

    The following bibliography presents brief summaries of documents relevant to Conservation Reserve Program relations to wildlife habitat, habitat management in agriculturally dominated landscapes, and conservation policies potentially affecting wildlife habitats in agricultural ecosystems. Because the literature summaries furnished provide only sweeping overviews, users are urged to obtain and evaluate those papers appearing useful to obtain a more complete understanding of study findings and their implications to conservation in agricultural ecosystems. The bibliography contains references to reports that reach beyond topics that directly relate to the Conservation Reserve Program. Sections addressing grassland management and landowner surveys/opinions, for example, furnish information useful for enhancing development and administration of conservation policies affecting lands beyond those enrolled in conservation programs. Some sections of the bibliography (for example, agricultural conservation policy, economics, soils) are far from inclusive of all relevant material written on the subject. Hopefully, these sections will serve as fundamental introductions to related issues. In a few instances, references may be presented in more than one section of the bibliography. For example, individual papers specifically addressing both non-game and game birds are included in respective sections of the bibliography. Duplication of citations and associated notes has, however, been kept to a minimum.

    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.

    2008-01-01

    This paper proposes and analyses the autoregressive conditional root (ACR) time-series model. This multivariate dynamic mixture autoregression allows for non-stationary epochs. It proves to be an appealing alternative to existing nonlinear models, e.g. the threshold autoregressive or Markov...... switching class of models, which are commonly used to describe nonlinear dynamics as implied by arbitrage in presence of transaction costs. Simple conditions on the parameters of the ACR process and its innovations are shown to imply geometric ergodicity, stationarity and existence of moments. Furthermore...

    A goal of an imaging accreditation program is to ensure adequate image quality, verify appropriate staff qualifications, and to assure patient and personnel safety. Currently, more than 35,000 facilities in 10 modalities have been accredited by the American College of Radiology (ACR), making the ACR program one of the most prolific accreditation options in the U.S. In addition, ACR is one of the accepted accreditations required by some state laws, CMS/MIPPA insurance and others. Familiarity with the ACR accreditation process is therefore essential to clinical diagnostic medical physicists. Maintaining sufficient knowledge of the ACR program must include keeping up-to-date as the various modality requirements are refined to better serve the goals of the program and to accommodate newer technologies and practices. This session consists of presentations from authorities in four ACR accreditation modality programs, including magnetic resonance imaging, computed tomography, nuclear medicine, and mammography. Each speaker will discuss the general components of the modality program and address any recent changes to the requirements. Learning Objectives: To understand the requirements of the ACR MR Accreditation program. The discussion will include accreditation of whole-body general purpose magnets, dedicated extremity systems well as breast MRI accreditation. Anticipated updates to the ACR MRI Quality Control Manual will also be reviewed. To understand the requirements of the ACR CT accreditation program, including updates to the QC manual as well as updates through the FAQ process. To understand the requirements of the ACR nuclear medicine accreditation program, and the role of the physicist in annual equipment surveys and the set up and supervision of the routine QC program.

    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.

    Patients presenting with myelopathic symptoms may have a number of causative intradural and extradural etiologies, including disc degenerative diseases, spinal masses, infectious or inflammatory processes, vascular compromise, and vertebral fracture. Patients may present acutely or insidiously and may progress toward long-term paralysis if not treated promptly and effectively. Noncontrast CT is the most appropriate first examination in acute trauma cases to diagnose vertebral fracture as the cause of acute myelopathy. In most nontraumatic cases, MRI is the modality of choice to evaluate the location, severity, and causative etiology of spinal cord myelopathy, and predicts which patients may benefit from surgery. Myelopathy from spinal stenosis and spinal osteoarthritis is best confirmed without MRI intravenous contrast. Many other myelopathic conditions are more easily visualized after contrast administration. Imaging performed should be limited to the appropriate spinal levels, based on history, physical examination, and clinical judgment. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every three years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals, and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. Copyright © 2016 American College of Radiology.

    A fundamental consideration in the workup of a jaundiced patient is the pretest probability of mechanical obstruction. Ultrasound is the first-line modality to exclude biliary tract obstruction. When mechanical obstruction is present, additional imaging with CT or MRI can clarify etiology, define level of obstruction, stage disease, and guide intervention. When mechanical obstruction is absent, additional imaging can evaluate liver parenchyma for fat and iron deposition and help direct biopsy in cases where underlying parenchymal disease or mass is found. Imaging techniques are reviewed for the following clinical scenarios: (1) the patient with painful jaundice, (2) the patient with painless jaundice, and (3) the patient with a nonmechanical cause for jaundice. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel.

    C-reactive protein (CRP) is a phylogenetically highly conserved plasma protein, which is widely used as an indicator of inflammatory states due to rapid increase of its plasma concentration up to 1000 times compared to normal values. Detection of CRP levels in a rapid, simultaneous and multiplex format is therefore of great interest for diagnostics. Microarray technology could provide such a multiplex format of CRP levels detection. Different nanostructured porous silicon (PS) surfaces were obtained and used for the immobilization of CRP and anti-human CRP antibodies in order to achieve an optimum microarray assay. Comparative analysis of the attachment degree and preservation of the biomolecules activity on the silicon surfaces and functionalized glass slides is also described.

    2006-03-01

    The accreditation programs of the American College of Radiology (ACR) are the most established and widely proven for all imaging modalities. For facilities committed to quality imaging, the ACR Nuclear Medicine and PET Accreditation Program provides a solid foundation for a continuous quality improvement program through a peer review and educational process. This article provides general information describing the goals and development of the ACR accreditation programs. The ACR Nuclear Medicine and PET Accreditation Program evaluates the qualifications of personnel, equipment, image quality, and quality control measures. It is believed that these are the primary factors that have an impact on the quality of patient imaging. This article describes the application process, including the clinical examinations that are required and the quality control and performance tests that are expected from each facility. Outcomes and pass/fail statistics are discussed, as are common pitfalls that may cause deficiencies. Upon completion of this article, the reader should be able to describe the application process, the components of the ACR accreditation program, the most common causes for failure, and the site survey process.

A recent study showed that aggressive statin treatment caused reductions of 50% in LDL cholesterol, 37% in CRP, 44% in CVD events, and 20% in total mortality, and that the highest treatment benefits were obtained in those with the lowest achieved levels of both LDL......AIM: To evaluate recent human studies with respect to the interpretation of whether elevated plasma levels of C-reactive protein (CRP) cause cardiovascular disease (CVD), or whether elevated CRP levels more likely is an innocent bystander. DATA SYNTHESIS: Elevated CRP concentrations...... cholesterol and CRP. However, a reduction in CRP levels after statin treatment could be secondary to the reduced LDL cholesterol levels, and thereby less inflammation in atherosclerotic plaques. We recently performed 4 large Mendelian randomization studies, studies that demonstrated that elevated CRP...

    Crohn disease is a chronic inflammatory disorder involving the gastrointestinal tract, characterized by episodic flares and times of remission. Underlying structural damage occurs progressively, with recurrent bouts of inflammation. The diagnosis and management of this disease process is dependent on several clinical, laboratory, imaging, endoscopic, and histologic factors. In recent years, with the maturation of CT enterography, and MR enterography, imaging has played an increasingly important role in relation to Crohn Disease. In addition to these specialized examination modalities, ultrasound and routine CT have potential uses. Fluoroscopy, radiography, and nuclear medicine may be less beneficial depending on the clinical scenario. The imaging modality best suited to evaluating this disease may change, depending on the target population, severity of presentation, and specific clinical situation. This document presents seven clinical scenarios (variants) in both the adult and pediatric populations and rates the appropriateness of the available imaging options. They are summarized in a consolidated table, and the underlying rationale and supporting literature are presented in the accompanying narrative. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every three years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. Copyright © 2015 American College of Radiology.

    Pourahmad Jaktaji, Razieh; Jazayeri, Nasim

    2013-12-01

    The major antibiotic efflux pump of Esherichia coli is AcrAB-TolC. The first part of the pump, AcrAB, is encoded by acrAB operon. The expression of this operon can be kept elevated by overexpression of an activator, MarA following inactivation of MarR and AcrR repressors due to mutation in encoding genes, marR and acrR, respectively. The aims of this research were to use E. coli mutants with or without mutation in marR to search for the presence of possible mutation in acrR and to quantify the expression of acrAB. The DNA binding region of acrR gene in these mutants were amplified by PCR and sequenced. The relative expression of acrA and acrB were determined by real time PCR. RESULTS showed that W26 and C14 had the same mutation in acrR, but none of the mutants overexpressed acrA and acrB in comparison with wild type strain. The effect of marR or acrR mutation on acrAB overexpression is dependent on levels of resistance to tetracycline and ciprofloxacin.

    At promoters of the Escherichia coli CytR regulon, the cAMP receptor protein (CRP) interacts with the repressor CytR to form transcriptionally inactive CRP-CytR-promoter or (CRP)(2)-CytR-promoter complexes. Here, using "oriented heterodimer" analysis, we show that only one subunit of the CRP dime...

    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.

    Atomic Energy of Canada Ltd. (AECL), via its 100% owned US subsidiary AECL Technologies Inc., is performing a pre-application review of the Advanced CANDU Reactor (ACR) with the US Nuclear Regulatory Commission (USNRC). Completion of this pre-application review by mid-2004, is in support of an application to the USNRC for Standard Design Certification that is targeted for the fall of 2004. The intent of the pre-application review is to deal up-front with potential issues associated with the CANDU reactor genealogy of the ACR that are different from the Light Water Reactor (LWR) and Boiling Water Reactor (BWR) regulatory framework in the USA. The focus of the paper will be to describe the pre-application review process currently underway with the NRC staff. In the context of the pre-application review this paper will provide an overview of the licensing approach being used to introduce the ACR-700 to the USA. (author)

    2015-01-01

    Arteriovenous Fistula (AVF) is the ideal method of vascular access for patients on maintenance hemodialysis (HD). Therefore it is an important part of treatment in HD. There are several observations that indicate the role of inflammation in failure of AVF. The aim of this study was to evaluate the hematologic and inflammatory biomarkers in early AVF failure. This case-control study included 110 ESRD patients, whom were undergone AVF creation, divided in two groups. About 700 radius-cephalic AVF were created during these two years. We found 55 cases with AVF failure. In this study, we compared those 55 failures with 55 functional AVF which were selected using randomized sampling from the rest of patients according to age, gender, and AVF location. Levels of serum C-reactive protein (CRP) were checked in both groups to evaluate the relation between AVF failure and CRP level before surgery. The mean±SD age of the patients was 49.7±17.28 years. CRP was positive in 34 patients (61.8%) with unsuccessful fistula function, while only 4 (7.3%) of those with successful AVF had positive CRP and the rest had negative CRP. The difference between the two groups of patients was strongly significant (pfistula function.

    C-reactive protein (CRP) is a useful prognostic factor in coronary heart disease. It has not been previously studied in acute cerebro-vascular events, which was the topic of the present study. Patients admitted to the hospital for an acute cerebro-vascular event were prospectively investigated. C-reactive protein was determined nephelometrically. Infection or inflammation were excluded clinically and with an erythrocyte sedimentation rate brain was performed. According to initial brain imaging and the clinical course the 138 patients were divided into five groups: 20 with transient ischemic attack, 20 with reversible neurological deficit lasting less than 2 weeks, 61 with completed stroke and restitution, 16 with stroke without restitution and 21 with cerebral hemorrhage. Median CRP values (range) were 3.2 (2.4-13.5), 3.3 (2.4-39.4), 4.2 (2.4-73. 4), 3.4 (3.2-44.0) and 3.5 (2.4-104.0 mg/l), respectively with no significant differences between groups in a non-parametric test (Kruskal-Wallis). Risk factors for vascular disease in general and stroke in particular had no visible influence on CRP levels. No relationship was found between time interval since onset of symptoms and CRP measurement, suggesting that an acute cerebro-vascular event has little influence on CRP values. CRP is not a useful marker to predict the outcome of an acute cerebro-vascular event on hospital admission. This is in contrast to acute coronary events.

    Albumin/creatinine ratio (ACR) from a first morning urine is recommended as a early indicator for diabetic nephropathy. However, it is not always feasible to collect the first morning urine for outpatients. We aimed to explore whether ACR from a second morning urine had a good consistency with that from a first morning urine to predict albuminuria in Chinese elderly citizens. One hundred and ninety-one elderly citizens (≧60 years old) from Junliangcheng community, Dongli district, Tianjin, China were included. A first and second morning urine was collected from each participants, successfully and detected the urinary albumin and creatinine of each urine sample. Albumin to creatinine ratio from a first morning urine (ACR1) was compared with that from a second morning urine (ACR2), and the ability of ACR1 and ACR2 to predict albuminuria was assessed. ACR1 and ACR2 were highly correlated (r = 0.901), especially in male and hypertension group (r = 0.938 and 0.904). The slope and intercept were 0.93 and 0.11 after log-transformed. And there was no statistical difference between values of ACR1 and ACR2 (P = 0.271). Overall, 26.2% participants were detected with albuminuria when judged by ACR1 and 28.3% by ACR2. A good concordance of ACR category (normal or albuminuria) was found between ACR1 and ACR2 (Kappa value = 0.815 in overall; in male and hypertension group were 0.900 and 0.850). A second morning urine ACR could be the alternative to a first morning urine ACR for albuminuria detection in elderly population. © 2015 Wiley Periodicals, Inc.

    Pasteurella multocida (P. multocida) is an important veterinary pathogen that can cause severe diseases in a wide range of mammals and birds. The global regulator crp gene has been found to regulate the virulence of some bacteria, and crp mutants have been demonstrated to be effective attenuated vaccines against Salmonella enterica and Yersinia enterocolitica. Here, we first characterized the crp gene in P. multocida, and we report the effects of a crp deletion. The P. multocida crp mutant exhibited a similar lipopolysaccharide and outer membrane protein profile but displayed defective growth and serum complement resistance in vitro compared with the parent strain. Furthermore, crp deletion decreased virulence but did not result in full attenuation. The 50 % lethal dose (LD50) of the Δcrp mutant was 85-fold higher than that of the parent strain for intranasal infection. Transcriptome sequencing analysis showed that 92 genes were up-regulated and 94 genes were down-regulated in the absence of the crp gene. Finally, we found that intranasal immunization with the Δcrp mutant triggered both systematic and mucosal antibody responses and conferred 60 % protection against virulent P. multocida challenge in ducks. The deletion of the crp gene has an inhibitory effect on bacterial growth and bacterial resistance to serum complement in vitro. The P. multocida crp mutant was attenuated and conferred moderate protection in ducks. This work affords a platform for analyzing the function of crp and aiding the formulation of a novel vaccine against P. multocida.

    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.

    2016-02-01

    Osteonecrosis of the hip (Legg-Calvé-Perthes) is a common disease, with 10,000-20,000 symptomatic cases annually in the United States. The disorder affects both adults and children and is most frequently associated with trauma and corticosteroid usage. The initial imaging evaluation of suspected hip osteonecrosis is done using radiography. MRI is the most sensitive and specific imaging modality for diagnosis of osteonecrosis of the hip. The clinical significance of hip osteonecrosis is dependent on its potential for articular collapse. The likelihood of articular collapse is significantly increased with involvement of greater than 30%-50% of the femoral head area, which is optimally evaluated by MRI, often in the sagittal plane. Contrast-enhanced MRI may be needed to detect early osteonecrosis of the hip in pediatric patients, revealing hypoperfusion. In patients with a contraindication for MRI, use of either CT or bone scintigraphy with SPECT (single-photon emission CT) are alternative radiologic methods of assessment. Imaging helps guide treatment, which may include core decompression, osteotomy, and ultimately, need for joint replacement. The ACR Appropriateness Criteria(®) are evidence-based guidelines for specific clinical conditions that are reviewed every three years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. Copyright © 2016 American College of Radiology.

    This study tested the hypothesis that during massive proteinuria, C-reactive protein (CRP) may be lost into the urine along with other proteins, making serum CRP (sCRP) level an unreliable marker of infection severity in nephrotic syndrome (NS). Children with active NS (n = 23) were compared with two matched control groups: patients with febrile non-renal infectious disease (n = 30) and healthy subjects (n = 16). Laboratory measurements included sCRP, urine protein, creatinine, IgG, and protein electrophoresis. Urinary CRP (uCRP) was measured by ELISA. Sixty-nine patients were enrolled: 23 patients with NS, 30 patients with non-renal febrile infectious diseases, and 16 healthy children. Median uCRP concentrations were 0 mcg/gCr (0-189.7) in NS, 11 mcg/gCr (0-286) in the febrile group, and 0 mcg/gCr (0-1.8) in the healthy group. The uCRP/creatinine ratio was similar in the NS and healthy groups (p > 0.1) and significantly higher in the febrile group than the other two groups (p < 0.0001). There was no association of uCRP concentration with severity of proteinuria or IgG excretion. NS in children is not characterized by significant loss of CRP into the urine. Therefore, sCRP may serve as a reliable marker of inflammation in this setting. The significant urinary excretion of CRP in children with transient non-renal infectious disease might be attributable to CRP synthesis in renal epithelial cells.

  8. Computational prediction of cAMP receptor protein (CRP binding sites in cyanobacterial genomes

    Directory of Open Access Journals (Sweden)

    2009-01-01

    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 CRP is a recognized marker of systemic inflammation. The degree to which CRP is associated with carotid and/or femoral intima media thickness (IMT, markers of atherosclerosis, may quantify the degree to which inflammation explains cardiovascular disease in patients with end stage renal disease. The purpose of this study was to estimate the association between CRP and both carotid and femoral IMT in hemodialysis (HD patients. The present cross-sectional study is nested in the Sevelamer hydrochloride and ultrasound-measured femoral and carotid intima media thickness progression in end stage renal disease (SUMMER clinical trial. Carotid (common, internal and bifurcation and femoral arteries were visualized in B-mode ultrasonography. CRP was measured in serum. The study cohort included 177 HD patients (39.5% female, mean age 67.8±11.5 years. All measures of both carotid and femoral IMT were significantly, positively associated with CRP. Compared to subjects without, subjects with PVD, coronary revascularization and hypertension had significantly higher CRP levels. Conversely, subjects treated with sevelamer hydrochloride had significantly lower CRP levels than those not exposed to this medication. CRP was significantly, positively associated with serum phosphorus, calcium and PTH, and significantly inversely associated with HDL. In conclusion, CRP is significantly, positively associated with both femoral and carotid IMT and suggests an association between inflammation and atherosclerosis in HD patients.

    The physiology of inflammatory response is modified by the aging process and is substantially affected by multimorbidity and disability. Infection is the most frequent cause of acute inflammation in both adult and older subjects. C-reactive protein (CRP) is the most used biomarker of inflammation, and a substantial amount of literature has demonstrated its importance and clinical usefulness in adult subjects. However, the clinical significance of serum CRP determination has not been completely clarified in older subjects with acute infection, especially in the light of the age-related rearrangements in immunity and cytokine production. Thus, in the present review, we focus on the existing knowledge about serum CRP level interpretation in geriatric patients hospitalized with acute infection. Our aims were to determine the significance of CRP measurement at hospital admission for establishing a diagnosis of infection and/or a prognosis and to evaluate whether it is indicated to repeat hs-CRP measurements during hospital stay for monitoring disease course and, possibly, guiding the discharge timing. We concluded that CRP dosage at hospital admission is helpful to detect acute infection, and particularly sepsis, in geriatric patients, and that CRP elevation may provide valuable short-term prognostic information. At the current state of art, serial CRP measurements are instead not indicated to monitor disease course and plan hospital discharge in this setting.

  14. Cysteine-rich protein 1 (CRP1 regulates actin filament bundling

    Directory of Open Access Journals (Sweden)

    Fraley Tamara S

    2005-12-01

    Full Text Available Abstract Background Cysteine-rich protein 1 (CRP1 is a LIM domain containing protein localized to the nucleus and the actin cytoskeleton. CRP1 has been demonstrated to bind the actin-bundling protein α-actinin and proposed to modulate the actin cytoskeleton; however, specific regulatory mechanisms have not been identified. Results CRP1 expression increased actin bundling in rat embryonic fibroblasts. Although CRP1 did not affect the bundling activity of α-actinin, CRP1 was found to stabilize the interaction of α-actinin with actin bundles and to directly bundle actin microfilaments. Using confocal and photobleaching fluorescence resonance energy transfer (FRET microscopy, we demonstrate that there are two populations of CRP1 localized along actin stress fibers, one associated through interaction with α-actinin and one that appears to bind the actin filaments directly. Consistent with a role in regulating actin filament cross-linking, CRP1 also localized to the membrane ruffles of spreading and PDGF treated fibroblasts. Conclusion CRP1 regulates actin filament bundling by directly cross-linking actin filaments and stabilizing the interaction of α-actinin with actin filament bundles.

    C-reactive protein (CRP) is a well-known marker of inflammation and infection in clinical practice. This study is designed to evaluate CRP levels in different phases of menstrual cycle, which might end up with misleading conclusions especially when used for cardiovascular risk assessment. Twenty-seven women were eligible for the cross-sectional study. Venous blood samples from each participant were collected twice during the menstrual cycle. The first sampling was held at 2nd to 5th days of the menstrual cycle for FSH, estradiol, CRP, and sedimentation, and the second was done at 21st to 24th days of the menstrual cycle for measurement of progesterone, CRP, and sedimentation values. CRP values were significantly higher in the early follicular phase compared to luteal phase (1.8 mg/L [0.3-7.67] vs. 0.7 mg/L [0.1-8.3], p menstrual cycle, sedimentation rate was similar (12.1 ± 6.7 vs. 12.3 ± 7.7; p = 0.717, respectively). CRP levels in early follicular phase of the menstrual cycle (menstruation) are significantly higher than CRP levels in luteal phase of the same cycle. In reproductive age women, detection of CRP for cardiovascular risk assessment during menstruation might not be appropriate.

    Despite the fact that C-reactive protein (CRP) levels and white blood cell (WBC) count are routine blood chemistry parameters for the early assessment of wound infection after surgical procedures, little is known about the natural history of their serum values after major and minimally invasive spinal procedures. Pre- and postoperative CRP serum levels and WBC count in 347 patients were retrospectively assessed after complication-free, single-level open posterior lumbar interlaminar fusion (PLIF) (n = 150) for disc degeneration and spinal stenosis and endoscopically assisted lumbar discectomy (n = 197) for herniated lumbar disc. Confounding variables such as overweight, ASA classification, arterial hypertension, diabetes mellitus, and perioperative antibiotics were recorded to evaluate their influence on the kinetics of CRP values and WBC count postoperatively. In both procedures, CRP peaked 2-3 days after surgery. The maximum CRP level was significantly higher after fusion: mean 127 (SD 57) (p 25 and long duration of surgery were associated with higher peak CRP values. WBC count did not show a typical and therefore interpretable profile. CRP is a predictable and responsive serum parameter in postoperative monitoring of inflammatory responses in patients undergoing spine surgery, whereas WBC kinetics is unspecific. We suggest that CRP could be measured on the day before surgery, on day 2 or 3 after surgery, and also between days 4 and 6, to aid in early detection of infectious complications.

    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.

    To assess the trends of women in voluntary leadership roles in the ACR from 2001 to 2015. Retrospective leadership records from 2001 to 2015 were collected from the ACR Membership Database based on member demographics, gender, and participation in leadership roles at the national and state level. Data were sorted by gender and year to assess the proportion of women in each leadership position relative to total member/representation counts. Overall, there were increasing numbers of women represented in ACR leadership. From 2001 to 2015, there were increasing rates of women achieving fellowship in the College (7%-11%), now at parity with male member rates. Representation by women has risen from 7% to 21% for state chapter presidents and from 14% to 18% for state councilors. Comparing rolling 5-year averages from 2001-2005 and 2011-2015 showed statistically significant increases (P leadership roles. Women members of the council steering committee rose from 13% in 2001 to 19% in 2015, peaking at 24% in 2014. The Board of Chancellors (BOC) showed the largest increase in women, from 9% to 33%, with a peak at 37% in 2014. However, no BOC chairs were women, one council speaker was a woman, two women were ACR presidents, and two women were vice presidents. Women's participation in ACR leadership has increased significantly at the state level and in fellowship recognition. Although there are increasing numbers of women on the BOC, top positions remain male-dominated at the national level. Published by Elsevier Inc.

    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

    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). A comparative cross-sectional study. Mayo Hospital, Lahore, from January to June 2010. 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. Chi-square 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 ² 0.05 was taken as significant. 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. 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 only linked to hypertriglyceridemia but vascular inflammation among pre-obese and obese

    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.

    To achieve the switch from conventional analog-based design to digital design in ACRs, a large number of manual operating controls and switches have to be replaced by a few common multi-function devices which is called soft control system. The soft controls in APR-1400 ACRs are classified into safety-grade and non-safety-grade soft controls; each was designed using different and independent input devices in ACRs. The operations using soft controls require operators to perform new tasks which were not necessary in conventional controls such as navigating computerized displays to monitor plant information and control devices. These kinds of computerized displays and soft controls may make operations more convenient but they might cause new types of human error. In this study the human error mechanism during the soft controls is studied and modeled to be used for analysis and enhancement of human performance (or human errors) during NPP operation. The developed model would contribute to a lot of applications to improve human performance (or reduce human errors), HMI designs, and operators' training program in ACRs. The developed model of human error mechanism for the soft control is based on assumptions that a human operator has certain amount of capacity in cognitive resources and if resources required by operating tasks are greater than resources invested by the operator, human error (or poor human performance) is likely to occur (especially in 'slip'); good HMI (Human-machine Interface) design decreases the required resources; operator's skillfulness decreases the required resources; and high vigilance increases the invested resources. In this study the human error mechanism during the soft controls is studied and modeled to be used for analysis and enhancement of human performance (or reduction of human errors) during NPP operation.

    To compare the Disease Activity Score with 28 joint (DAS28) using erythrocyte sedimentation rate (ESR) (DAS28-ESR) and DAS28 using C-reactive protein (CRP) (DAS28-CRP) with thresholds validated for DAS28-ESR in Turkish patients with rheumatoid arthritis. The DAS28 data of 112 patients with rheumatoid arthritis followed in a local outpatient clinic were used. First, the correlation between DAS28-CRP and DAS28-ESR and the correlation between their unique components ([0.36 × In (CRP + 1) + 0.96] and [0.70 × In (ESR)]) were analyzed. Second, a Bland-Altman plot was constructed for the evaluation of the level of agreement between DAS28-CRP and DAS28-ESR. Lastly, the agreement between these two methods was analyzed by κ coefficient. Although there was a strong correlation between DAS28-CRP and DAS28-ESR, the correlation between their unique components was fair. Although more than 95% of the point data fall between the upper and lower bounds of the limit of agreement, the percentage error (46%) was higher than the acceptable proportion of 30%. The κ coefficient of agreement between DAS28- ESR and DAS28-CRP with validated thresholds for DAS28-ESR was 0.42, which was close to the lower boundary for moderate agreement. The results of this study demonstrated that there is discordance between DAS28-ESR and DAS28-CRP with the validated thresholds for DAS28-ESR. Using the DAS28-CRP with threshold values validated for DAS28-ESR may lead to errors in the determination of disease activity and therefore may lead to errors in the management of patients with rheumatoid arthritis. © 2015 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

    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 Abstract Background Both C reactive protein (CRP and procalcitonin (PCT are well known acute phase reactant proteins. CRP was reported to increase in metabolic syndrome and type-2 diabetes. Similarly altered level of serum PCT was found in chronic liver diseases and cirrhosis. The liver is considered the main source of CRP and a source of PCT, however, the serum PCT and CRP levels in non-alcoholic fatty liver disease (NAFLD were not compared previously. Therefore we aimed to study the diagnostic and discriminative role of serum PCT and CRP in NAFLD. Methods Fifty NAFLD cases and 50 healthy controls were included to the study. Liver function tests were measured, body mass index was calculated, and insulin resistance was determined by using a homeostasis model assessment (HOMA-IR. Ultrasound evaluation was performed for each subject. Serum CRP was measured with nephalometric method. Serum PCT was measured with Kryptor based system. Results Serum PCT levels were similar in steatohepatitis (n 20 and simple steatosis (n 27 patients, and were not different than the control group (0.06 ± 0.01, 0.04 ± 0.01 versus 0.06 ± 0.01 ng/ml respectively. Serum CRP levels were significantly higher in simple steatosis, and steatohepatitis groups compared to healthy controls (7.5 ± 1.6 and 5.2 ± 2.5 versus 2.9 ± 0.5 mg/dl respectively p Conclusion Serum PCT was within normal ranges in patients with simple steatosis or steatohepatitis and has no diagnostic value. Serum CRP level was increased in NAFLD compared to controls. CRP can be used as an additional marker for diagnosis of NAFLD but it has no value in discrimination of steatohepatitis from simple steatosis.

    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.

    Inflammation contributes to vascular disease progression. However, the role of circulating inflammatory molecules on microvascular endothelial cell (mECs) is not fully elucidated. The aim of this study was to investigate the effects of the short pentraxin CRP on microvascular endothelial cell angiogenic function. Subcutaneously implanted collagen plugs seeded with human mECs exposed to monomeric CRP (mCRP) in mice showed formation of an extended network of microvessels both in the plug and the overlying skin tissue, while mECs exposure to pentameric native CRP (nCRP) induced a much milder effect. To understand the mechanisms behind this angiogenic effects, mECs were exposed to both CRP forms and cell migration, wound repair and tube-like formation were investigated. nCRP effects were moderate and of slow-onset whereas mCRP induced rapid, and highly significant effects. We investigated how circulating nCRP is transformed into mCRP by confocal microscopy and western blot. nCRP is transformed into mCRP on the mECs membranes in a time dependent fashion. This transformation is specific and in part receptor dependent, and the formed mCRP triggers F3 gene transcription and TF-protein expression in mECs to induce angiogenesis. F3-silenced mECs are unable to form angiotubes. In agreement, mCRP induced upregulation of the TF signalling pathway in mECs with downstream phosphorylation of AKT and activation of the transcription factor ETS1 leading to increased CCL2 release. The circulating pentraxin nCRP with little pro-angiogenic effect when dissociated into mCRP on the surface of mECs is able to trigger potent proangiogenic effects by inducing F3-gene upregulation and TF signalling.

    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.

    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

    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. 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. 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 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.

    There is a known association between C-reactive protein (CRP) levels and adverse outcomes in patients presenting with ST-elevation myocardial infarction (STEMI). The optimal time frame to measure CRP for risk stratification is not known. The aim of the current study was to evaluate the relation between the change in CRP velocity (CRPv) and 30-d mortality among STEMI patients. We included consecutive patients with a diagnosis of STEMI who presented to Tel-Aviv Medical Center between 2008 and 2014 and had their CRP measured with a wide range assay (wr-CRP) at least twice during the 24 h after admission. CRPv was defined as the change in wr-CRP concentration (mg/l) divided by the change in time (in hours) between the two measurements. The study population comprised of 492 patients, mean age was 62 ± 14, 80% were male. CRPv was significantly higher among patients who died within 30 d of admission (1.42 mg/l versus 0.18 mg/l, p < 0.001). In a multivariate regression model adjusted to multiple confounders, CRPv was independently associated with 30-d mortality (OR 1.39, 95% CI: 1.20-1.62, p < 0.001). CRPv might be an independent and rapidly measurable biomarker for short-term mortality in patients presenting with STEMI.

    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.

    Patients with active acromegaly have 2- to 3-fold increased cardiovascular mortality. Alterations of acute phase proteins, observed in acromegaly, could lead to cardiovascular diseases. Aim of the study was to evaluate fibrinogen and C-reactive protein (CRP) secretion in patients with acromegaly. Seventy-seven patients were divided into groups with active (AA, n = 56) and controlled acromegaly (CA, n = 21). Twenty age- and sex-matched healthy subjects served as controls. Serum fibrinogen, CRP, fasting glucose, insulin, total cholesterol, LDL and HDL cholesterol, and triglycerides were measured, and body mass index (BMI) was calculated. Comparison between the groups revealed: higher fibrinogen, triglycerides, glucose levels, and BMI values in AA than in the controls; higher CRP, fibrinogen, triglyceride levels, and BMI values in CA than in the controls; higher LDL cholesterol and insulin levels and lower CRP levels and BMI values in the AA group than in the CA group. Fibrinogen concentration was highest in the AA group and lowest in the control group. Fibrinogen levels were high in all patients with acromegaly, irrespective of disease status, and they were significantly higher than in healthy subjects. CRP concentration was highest in the CA group and lowest in the control group. CRP levels were significantly and paradoxically lower in patients with AA than in patients with well-controlled disease and did not explain the increased cardiovascular mortality in acromegaly. Fibrinogen plays an important role as a cardiovascular risk factor in acromegaly, irrespective of the cure of the disease. The role of CRP as a cardiovascular risk factor in patients with uncontrolled acromegaly should be better explained in future studies. (Pol J Endocrinol 2010; 61 (1): 83-88).

    Chronic spontaneous urticaria (CSU) is a common dermatological condition defined by the sudden occurrence of daily wheals and pruritus for at least six weeks. Multifactorial origin is suggested such as oxidative stress. This latter may play a double role as a trigger and remnant agent. The first aim of this study is to investigate antioxidant status, inflammatory proteins, hematologic counts and clinical assessment in CSU patients. The second aim is to evaluate the effect of a first-line treatment: desloratadine 5 mg/d on these different parameters. This study enrolled 30 CSU patients and same number of controls. We assessed the urticaria activity score (UAS), total antioxidant status (TAS), glutathione S-transferase (GST), superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), albumin, alpha1, alpha2, beta1 beta2, gamma globulins, c-reactive protein (CRP) and hematologic numeration. At baseline alpha1, alpha2, beta1, beta2, gamma globulins, CRP, SOD activity, leukocytes and basophils were significantly higher in patients versus controls (p < 0.05). TAS, GST, CAT, GPx and albumin were significantly low in patients versus controls (p < 0.05). After treatment, TAS, GST and GPx were significantly increased in patients versus patients before treatment (p < 0.001). SOD, alpha1, alpha2, beta1, beta2, gamma globulins, CRP, albumin, leukocytes and basophils were significantly decreased after treatment versus before treatment (p < 0.05). A significant correlation between CRP and UAS (r = 0.3; p = 0.011) was noted. UAS assessment revealed the efficacy of 30 d-antihistaminic treatment. Desloratadine exerted anti-inflammatory and antioxidant effects on CSU patients revealed by CRP. Patients' remission was synergistic to CRP attenuation emphasizing CRP relevance for CSU clinical assessment.

    Full Text Available Introduction: Leptospirosis is an acute bacterial disease, that has global distribution and manifests itself in subclinical or asymptomatic way, having mild or severe conditions that can lead to the death of the patient. Objective: To identify, among the municipalities of the state of Acre, Brazil, those with the highest incidence of leptospirosis between 2010 and 2015, and in addition, to determine the prevalence of this disease between the sexes. Methods: Descriptive study, of documentary character, with epidemiological base and quantitative approach. It was made by available documents through the Department of Informatics of the Unified Health System of Brazil (DATASUS and also by the Health Secretary of State of Acre (SESACRE. Variables were selected as sex, age and year of notification. Regarding the analysis, it is emphasized that it was quantitative and descriptive and the results were presented in tables built in Microsoft Word. Results: It was found that the capital of the state of Acre, Rio Branco, led every year, contributing to the higher proportion of notifications related to leptospirosis. Regarding gender, there was a predilection for males and among age groups, the period of 20 to 39 years contributes to the greater number of cases of the disease. Conclusion: Leptospirosis is a worldwide public health problem and in the state of Acre, the high rainfall, the agglomeration of low income combined with inadequate sanitation, collaborate to infestation of transmitters animals, providing high rates of the disease. Thus, it appears that these high numbers can probably be attributed to the ineffectiveness of preventive activities, as well as insufficient investment directed to social policies and infrastructure sectors. Keywords: Infectious Disease. Leptospirosis. Prevalence. Incidence.

    The aim of this study was to assess the status of the radiology job market as represented by the ACR Jobs Board from October 2010 to June 2013. With the assistance of the ACR, data from the ACR Jobs Board from October 2010 through June 2013, including the numbers of monthly new job seekers, new job postings, and job posting clicks, were gathered and used to calculate a monthly competitive index, defined as the ratio of new job seekers to new job postings. During the study period, the mean number of new job seekers was 168 per month, which was significantly greater than the 84 average new job postings for any given month (P = .0002). There was no significant difference between 2011 and 2012 with regard to the number of new job seekers or job postings. Over the time period assessed, more new job seekers registered in October and November 2010, August to November 2011, and October and November 2012. These periods were also associated with the highest competitive index values. There were less job seekers in the winter and spring of 2011, 2012, and 2013, periods associated with lower competitive index values. ACR Jobs Board activity, measured by job posting clicks, was significantly higher in 2012 than in 2011 (P Jobs Board, there were consistently more new job seekers than job postings throughout the study period, and fall is the period in the year most associated with the highest competitive index for radiologist employment.

    2012-03-01

    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 KD = 2.25×10-9 (M). The secondary structure, contact sites with CRP protein, and application of this aptamer will be described.

  14. Advancing alternate tools: why science education needs CRP and CRT

    Ridgeway and Yerrick's paper, Whose banner are we waving?: exploring STEM partnerships for marginalized urban youth, unearthed the tensions that existed between a local community "expert" and a group of students and their facilitator in an afterschool program. Those of us who work with youth who are traditionally marginalized, understand the importance of teaching in culturally relevant ways, but far too often—as Ridgeway and Yerrick shared—community partners have beliefs, motives, and ideologies that are incompatible to the program's mission and goals. Nevertheless, we often enter partnerships assuming that the other party understands the needs of the students or community; understands how in U.S. society White is normative while all others are deficient; and understands how to engage with students in culturally relevant ways. This forum addresses the underlying assumption, described in the Ridgeway and Yerrick article, that educators—despite their background and experiences—are able to teach in culturally relevant ways. Additionally, I assert based on the finding in the article that just as Ladson-Billings and Tate (Teach Coll Rec 97(1):47-68, 1995) asserted, race in the U.S. society, as a scholarly pursuit, was under theorized. The same is true of science education; race in science education is under theorized and the use of culturally relevant pedagogy and critical race theory as a pedagogical model and analytical tool, respectively, in science education is minimal. The increased use of both would impact our understanding of who does science, and how to broaden participation among people of color.

  15. The role of low CRP values in the prediction of the development of acute diverticulitis.

    2016-01-01

    Computed tomography (CT) is the most appropriate imaging modality for the assessment of acute diverticulitis at the emergency unit. The aim of this study was to determine the clinical outcome of the patients presented first time with symptoms of acute diverticulitis and low CRP values. Two-hundred patients, who presented with the symptoms of acute diverticulitis and had CRP values under 150 mg/L, underwent abdominal CT examination on admission to Oulu University Hospital. The clinical parameters and radiological findings were compared in relation to clinical outcome both by means of univariate and multivariate analyses. Seventy-one (35.5 %) of the 200 patients presented on admission with complicated diverticulitis. CRP values between 100 and 150 mg/L predicted complicated disease, but the mean values of CRP between uncomplicated disease, 89 mg/L ± 39, and complicated disease, 101 mg/L ± 39, did not differ significantly. Free intra-abdominal fluid in CT was the only independent risk factor of the need for interventional therapy and treatment in the intensive care unit. Longevity of the patients and free fluid in CT predicted significantly prolonged hospitalization. Mortality was 1 % and older patients were significantly affected. The recurrence rate of acute diverticulitis was 24 % (43/177) in the whole group and 18 % (23/129) after uncomplicated diverticulitis. Low CRP values do not reliably predict uncomplicated disease in patients presented first time at the emergency unit with acute diverticulitis. We recommend that the need for abdominal CT is carefully evaluated according to the patient's clinical status, always even when the CRP value is under 150 mg/L.

    2014-01-01

    Diverticulitis is suspected when the patient has pain and tenderness on palpation on the lower left abdomen, fever and an elevated CRP level. After a confirmed diagnosis, outpatient therapy of uncomplicated diverticulitis is possible, according to the latest research results even without antimicrobial drugs. CT scanning is usually unnecessary when the CRP level remains below 50 mg/l in the absence of signs of peritoneal irritation, but should always be performed when the value exceeds 150 mg/l. Unenhanced CT scan without contrast agent is well suited for the exclusion of complicated diverticulitis.

    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. Rats treated with DHA (250 mg/kg, but not 125 mg/kg survived the lethal effects of CP, and showed a significant recovery of GFR; while their homogenates had markedly-reduced MDA- and TNF-α-, but -increased GSH-levels. Significant association was detected between creatinine level and those of MDA (r = 0.81, TNF-α r = 0.92 and GSH (r = -0

    The scope of this paper is to assess traffic accidents involving motorcycles, the victims involved and the increase in the fleet compared with other vehicles in Rio Branco, State of Acre. It is an epidemiological, descriptive and transversal study of accidents between 2005 and 2008 recorded by the Acre State Highway Department. There were 3,582 motorcycle accidents and 3,768 victims in the period. The motorcycle fleet increased by 72.8%, with involvement in accidents increasing by 42.2%, while accidents involving other vehicles only increased by 9.2%. As regards victims, there is a predominance of men, with rates of 561.1, with the age groups of between 20 and 29 and 30 and 39 being the highest, with 755.4 and 542.2, respectively. With reference to accident characteristics, the highest number of accidents - 32.4% - occurred in the afternoon, followed by the morning with 29.2% and the evening with 28.9%. 18.3% occurred on Saturdays and 15.7% on Sundays. Collisions were the commonest kind of accident, with 3,036 (84.8%) occurrences. The conclusion drawn is that it is essential to stage ongoing preventive programs and ensure greater integration among the institutions involved, with planning and campaigns to reverse the current situation.

  19. ACRE: Absolute concentration robustness exploration in module-based combinatorial networks

    KAUST Repository

    Kuwahara, Hiroyuki

    2017-03-01

    To engineer cells for industrial-scale application, a deep understanding of how to design molecular control mechanisms to tightly maintain functional stability under various fluctuations is crucial. Absolute concentration robustness (ACR) is a category of robustness in reaction network models in which the steady-state concentration of a molecular species is guaranteed to be invariant even with perturbations in the other molecular species in the network. Here, we introduce a software tool, absolute concentration robustness explorer (ACRE), which efficiently explores combinatorial biochemical networks for the ACR property. ACRE has a user-friendly interface, and it can facilitate efficient analysis of key structural features that guarantee the presence and the absence of the ACR property from combinatorial networks. Such analysis is expected to be useful in synthetic biology as it can increase our understanding of how to design molecular mechanisms to tightly control the concentration of molecular species. ACRE is freely available at https://github.com/ramzan1990/ACRE.

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.

    Full Text Available The Conservation Reserve Program (CRP is a voluntary set-aside program in the United States designed to amelioratesoil erosion, control crop overproduction, enhance water quality, and provide wildlife habitat by replacing crops with other forms of land cover. Because CRP includes primarily grass habitats, it has great potential to benefitdeclining North American grassland bird populations. We looked at the change in national and state population trends of grassland birds and related changes to cover-specific CRP variables (previous research grouped all CRP practices. Changes in national trends after the initiation of the CRP were inconclusive, but we observed signficant bird-CRP relations at the state level. Most bird-CRP relations were positive, except for some species associated with habitats that CRP replaced. Practice- and configuration-specific CRP variables were related to grassland bird trends, rather than a generic measure of all CRP types combined. Considering all CRP land as a single, distinct habitat type may obscure actual relations between birds and set-aside characteristics. Understanding and predictingthe effects of set-aside programs (like CRP or agri-environment schemes on grassland birds is complex and difficult. Because available broad-scale datasets are less than adequate, studies should be conducted at a variety of spatial and temporal scales.

    The CRP concentration has been identified as a cardiovascular risk factor in healthy volunteers and in patients with stable and unstable angina pectoris. There is little information about the comparability of the results of different CRP assays and it has also not been evaluated whether different assays give different associations with risk. We studied this in the APRAIS study, a study on 211 patients with unstable angina pectoris who were admitted to hospital and in whom we studied the association between the CRP concentration on admission and the in-hospital clinical course (refractiviness to medication). We used two different immunological methods: an in-house ELISA using polyclonal rabbit anti-human CRP antibodies as catching and tagging antibody and a commercial nephelometric method (Dade-Behring). The analytical variation was much smaller for the nephelometric method than for the in-house ELISA. Both methods gave higher levels in the refractory group than in the stabilized group, but only for the nephelometric method was this difference significant. Also, when the relative risk is calculated, it is clear that the more accurate nephelometric method can better discriminate between the two groups [RR 2.19 (95% CI 0.94-5.11) for the nephelometric method and RR 1.30 (95% CI 0.56-3.03) for the ELISA]. In conclusion, the nephelometric method measures the CRP concentration with a smaller intra- and interassay variation. The nephelometric method can also better discriminate between unstable angina patients who will be stabilized and those who are refractory during hospitalization.

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

    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.

    Background Owing to its ease of collection, saliva is potentially the sample of choice in diagnosis. Salivary biomolecules have provided a porthole in surveying a person’s health and well-being. Our study aims were (1) to demonstrate the effects of pre-analytical steps, collection and pre-processing techniques on salivary protein detection and (2) to establish an indication of salivary reference intervals for 3 biomolecules of clinical interest. Methods Saliva samples were collected from participants (n = 25, ages 20–35 years) using the following methods: no stimulation (resting/unstimulated), mechanical, and acid stimulation. The saliva was prepared for analysis by: unprocessed, post standard centrifugation in a container without any additives, and centrifugation using Centrifugal Filter Unit (Amicon® Ultra-0.5). AlphaLisa® assays were used to measure the levels of C-Reactive Protein (CRP), Immunoglobin (IgE) and myoglobin in saliva samples. Results Saliva flow rates were lowest with the resting/drooling collection method. The lowest total protein concentration was with acid stimulation. Unstimulated and mechanically stimulated collections produced no effect on the CRP and IgE levels while myoglobin levels were highest with the unstimulated collection. Acid stimulation had a negative impact on the measured concentrations of IgE and myoglobin (except for CRP levels). Conclusion Mechanical stimulation was the most viable option for collecting saliva without affecting the levels of CRP and myoglobin. The processing methods had an adverse effect on the concentration of total protein as well as on CRP and IgE concentrations. PMID:23369566

    Although inflammation has been shown to be implicated in the pathophysiology of atrial fibrillation (AF), little is known about its involvement in the accompanying atrial electrical remodeling expressed by P wave dispersion (P(disp)). Fifty hypertensive subjects with documented paroxysmal AF (AF group) and 50 matched for body mass index, sex and office systolic blood pressure (BP) subjects with no history of AF (SR group) were subjected to electrocardiogram (ECG) and P(disp) assessment, hs-CRP determination, a complete echocardiographic study and 24-h ambulatory BP monitoring. The AF as compared to the SR subjects were older by 14 years (P < 0.0001) and they exhibited lower office and 24-h diastolic BP (7 mm Hg, P < 0.0001 and by 8 mm Hg, P < 0.0001, respectively) and higher office and 24-h pulse pressure (by 4 mm Hg, P = 0.03 and 6 mm Hg, P = 0.001, respectively) mean values. A higher mean of left atrial (LA) diameter index (by 1.9 mm/m(2), P < 0.0001) and left ventricular mass index (by 16 g/m(2), P < 0.0001) were observed in the AF vs. SR group. P(disp) mean and hs-CRP median values were higher in the AF group (by 22 ms, P < 0.0005 and by 4.63 mg/l, P < 0.0005, respectively). Standard multiple and multiple logistic regression analysis identified log(10)(hs-CRP) as independent determinant of P(disp) and log(10)(CRP) and P(disp) as independent determinants of AF. In hypertensive subjects hs-CRP and P(disp) are interrelated and associated with AF, suggesting an active implication of inflammation in the atrial electrophysiological remodeling predisposing to AF.

    Serine/threonine-protein kinase-like protein ARABIDOPSIS CRINKLY4 (ACR4), a transmembrane protein of Arabidopsis thaliana, plays important roles in cell division and differentiation. Although accumulating studies shed light on the function of ACR4, the structure and catalytic mechanism of ACR4 remain to be elucidated. Here, we report the purification and enzymatic properties of the intracellular kinase domain (residues 464-799) of ACR4 (ACR4IKD). Through Ni-affinity chromatography and gel filter chromatography methods, we successfully obtain high-purity ACR4IKD protein from Escherichia coli. Dynamic light scattering and gel-filtration methods reveal that ACR4IKD distributes with high homogeneity and exists as a monomer in solution. In addition, the ACR4IKD protein has typical kinase activity with myelin basic protein (MBP) as the substrate. Our study may lay the foundation for structure determination of ACR4IKD and further functional research, for example, screening significant substrates of ACR4 in Arabidopsis thaliana.

    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.

    Full Text Available Abstract Background Route environments can be a potentially important factor in influencing people's behaviours in relation to active commuting. To better understand these possible relationships, assessments of route environments are needed. We therefore developed a scale; the Active Commuting Route Environment Scale (ACRES, for the assessment of bicyclists' and pedestrians' perceptions of their commuting route environments. Here we will report on the development and the results of validity and reliability assessments thereof. Methods Active commuters (n = 54 were recruited when they bicycled in Stockholm, Sweden. Traffic planning and environmental experts from the Municipality of Stockholm were assembled to form an expert panel (n = 24. The active commuters responded to the scale on two occasions, and the expert panel responded to it once. To test criterion-related validity, differences in ratings of the inner urban and suburban environments of Greater Stockholm were compared between the experts and the commuters. Furthermore, four items were compared with existing objective measures. Test-retest reproducibility was assessed with three types of analysis: order effect, typical error and intraclass correlation. Results There was a concordance in sizes and directions of differences in ratings of inner urban and suburban environments between the experts and the commuters. Furthermore, both groups' ratings were in line with existing objectively measured differences between the two environmental settings. Order effects between test and retest were observed in 6 of 36 items. The typical errors ranged from 0.93 to 2.54, and the intraclass correlation coefficients ranged from 'moderate' (0.42 to 'almost perfect' (0.87. Conclusions The ACRES was characterized by considerable criterion-related validity and reasonable test-retest reproducibility.

    2017-07-29

    The ACR Commission on Human Resources conducts an annual workforce survey to determine the makeup of the radiology workforce and to identify potential plans for hiring new staff in an attempt to understand our profession better. The Practice of Radiology Environment Database group leaders were asked to complete an electronic survey regarding the makeup of their present workforce by subspecialty, as well as the numbers and types of subspecialists hired in 2016 and the numbers and types of subspecialists expected to be hired in 2017 and 2020. They were also asked about midlevel practitioners. Twenty-six percent of practice leaders (477) representing 11,056 radiologists, 33% of all practicing radiologists in the United States, responded to the survey. The workforce distribution by practice type and radiologists' ages has been relatively stable since 2012. Six percent of the practicing workforce is over the age of 65 years. Sixteen percent of radiologists work part-time, and 21.5% of radiologists are female. The survey results indicate that 1,569 to 2,037 radiologists were hired in 2016. In 2017, 1,826 to 2,370 new job opportunities are anticipated, a 14.1% increase compared with 2016. For 2017, the subspecialists most recruited will be neuroradiologists, general interventionalists, after-hours radiologists, and body imagers. Approximately 2,156 midlevel practitioners are presently working and supervised by radiologists. The 2017 ACR workforce study shows an optimistic picture and outlook for those seeking jobs as practicing radiologists in 2017. For practice leaders, the market will be much more competitive than it has been in past years. Copyright © 2017 American College of Radiology. Published by Elsevier Inc. All rights reserved.

    Acr3 is a plasma membrane transporter, a member of the bile/arsenite/riboflavin transporter (BART) superfamily, which confers high-level resistance to arsenicals in the yeast Saccharomyces cerevisiae. We have previously shown that the yeast Acr3 acts as a low affinity As(III)/H+ and Sb(III)/H+ antiporter. We have also identified several amino acid residues that are localized in putative transmembrane helices (TM) and appeared to be critical for the Acr3 activity. In the present study, the topology of Acr3 was investigated by insertion of glycosylation and factor Xa protease cleavage sites at predicted hydrophilic regions. The analysis of the glycosylation pattern and factor Xa cleavage products of resulting Acr3 fusion constructs provide evidence supporting a topological model of Acr3 with 10 TM segments and cytoplasmically oriented N- and C-terminal domains. Next, we investigated the role of the hydrophilic loop connecting TM8 and TM9, the large size of which is unique to members of the yeast Acr3 family of metalloid transporters. We found that a 28 amino acid deletion in this region does not affect Acr3 folding, trafficking substrate binding, or transport activity. Finally, we constructed a homology-based structural model of Acr3 using the crystal structure of the Yersinia frederiksenii homologue of the human bile acid sodium symporter ASBT.

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

    Directory of Open Access Journals (Sweden)

    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

    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

    Full Text Available Aim: Premature ruptur of membranes (PROM means the rupture of membranes at least one hour before the active labor begins.It is named as preterm premature rupture of membranes( PretermPROM if the rupture occurs before the 37th weeks of gestation.Although the etiologies,complications and results of the PROM and PretermPROM are similar,it has been showed that the major reason for the PretermPROM is infection in choriodesidual unit. Material and Method: It is important to identify the maternal infection for protection against the negative outcomes of prematurity and preterm labor.To obtain the probable maternal infection we can use serum markers of inflamation like leucocyte count,C-reactive protein,ALP,beta-2 microglobulin,alfa-2 macroglobulin. Results: We observed the serum levels of CRP and ferritin in PROM and PretermPROM diagnosed patients.The aim of this trial was to asses the differences of serum CRP and fibrinogen consantrations in selected PROM and PretermPROM diagnosed cases to emphasize the importance of subclinical infection in these diseases. Discussion: According to the results of our trial we found that CRP levels were in normal range in control group but significantly higher in group with PROM and Preterm PROM.In groups with PROM and Preterm PROM avarege value of ferritin was significantly higher than control group.Present results supports that serum ferritin and CRP levels are useful for follow-up possible infections in pregnant women with PROM and Preterm PROM.

    Alpha-1 antitrypsin (AAT) deficiency and tobacco smoking are confirmed risk factors for Chronic Obstructive Pulmonary Disease. We hypothesized that variable DNA methylation would be associated with smoking and inflammation, as reflected by the level of C-Reactive Protein (CRP) in AAT-deficient subjects. Methylation levels of 1,411 autosomal CpG sites from the Illumina GoldenGate Methylation Cancer Panel I were analyzed in 316 subjects. Associations of five smoking behaviors and CRP levels with individual CpG sites and average methylation levels were assessed using non-parametric testing, linear regression and linear mixed effect models, with and without adjustment for age and gender. Univariate linear regression analysis revealed that methylation levels of 16 CpG sites significantly associated with ever-smoking status. A CpG site in the TGFBI gene was the only site associated with ever-smoking after adjustment for age and gender. No highly significant associations existed between age at smoking initiation, pack-years smoked, duration of smoking, and time since quitting smoking as predictors of individual CpG site methylation levels. However, ever-smoking and younger age at smoking initiation associated with lower methylation level averaged across all sites. DNA methylation at CpG sites in the RUNX3, JAK3 and KRT1 genes associated with CRP levels. The most significantly associated CpG sites with gender and age mapped to the CASP6 and FZD9 genes, respectively. In summary, this study identified multiple potential candidate CpG sites associated with ever-smoking and CRP level in AAT-deficient subjects. Phenotypic variability in Mendelian diseases may be due to epigenetic factors.

    Low levels of magnesium (Mg) are associated with chronic inflammatory stress. Some animal studies have reported that a moderate deficiency of Mg, similar to that which occurs in humans, may increase inflammatory or oxidative stress stimulated by other factors, such as disrupted sleep or sleep deficiency. This cross-sectional study evaluated the relationship between serum levels of Mg and the inflammatory response in patients with a new diagnosis of obstructive sleep apnea (OSA). This clinical, retrospective study registered 68 patients with newly diagnosed mild to severe OSA and 30 without OSA. The Apnea-Hypopnea Index (AHI), oxygen desaturation index (ODI), time until blood hemoglobin oxygen saturation OSA than those in controls matched for age, sex, and body mass index (BMI). Patients with OSA had substantially higher plasma CRP concentrations than controls. A negative correlation was observed between the AHI and ODI and Mg levels. Significant differences in Mg and CRP levels were observed between patients with AHI scores of 5-15 and scores ≥30 based on OSA severity but independent of BMI. Furthermore, the AHI, ODI, TST OSA. Low levels were associated with a higher CRP concentration in patients with OSA.

    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.

    Full Text Available Background Urinary tract infection (UTI is one of the most common infectious diseases and nosocomial infections worldwide, and uropathogenic Escherichia coli is the primary cause of UTI. Due to increased antibiotic resistance and the emergence of multidrug resistant (MDR UPEC clones, the treatment of UTI is difficult. The occurrence of MDR in E. coli has been attributed to the AcrAB-TolC complex of efflux pumps. Objectives The aim of this study was to complete a frequency evaluation of acrA and acrB genes among UPEC MDR strains isolated from patients with UTI who were admitted to Milad hospital in Tehran. Methods For 123 UPEC strains that were isolated and diagnosed from the urine samples of patients using biochemical tests, antibiotic susceptibility was carried out using the disc diffusion method according to CLSI guidelines. Isolates that were resistant to at least one antimicrobial agent in three or more of the categories were considered to be MDR. The presence and frequency of acrA and acrB genes was determined using PCR. Results The rates of antibiotic resistance to ampicillin, cefalotin, tetracycline, cefazolin, ceftriaxone, ceftizoxime, ceftazidime, ciprofloxacin, and cotrimoxazole were 82.9%, 78.1%, 61.1%, 49.5%, 38.2%, 30.2%, 26.1%, 42.2%, and 60.1%, respectively. The isolates were most sensitive to nitrofurantoin (95.9%, gentamicin (77.2%, and amikacin (71.5%. A total of 78% of the isolates were MDR. The frequency of the acrA gene was 82.90%, the acrB gene was 95.90% and acrA + acrB was 95.90%. There was no significant difference between acrA and acrB frequency relating to bacterial antibiotic resistance. Conclusions Our results showed that ways to control the treatment of UTI for the prevention of MDR occurrence should be sought. For a better study of efflux pumps, a comprehensive and detailed study regarding the presence of efflux pumps gees is required.

    The distribution of drug resistance among clinical isolates of Escherichia coli and Klebsiella pneumoniae has limited the therapeutic options. The aim of this study was to report the prevalence of quinolone resistance genes among E. coli and K. pneumoniae clinical strains isolated from three educational hospitals of Tehran, Iran. A total of 100 strains of E. coli from Labbafinejad and Taleghani Hospitals and 100 strains of K. pneumoniae from Mofid Children and Taleghani Hospitals were collected between January 2013 and May 2014. Antimicrobial susceptibility tests were done by disk diffusion method based on Clinical and Laboratory Standards Institute guidelines. Detection of qepA, aac(6')-Ib-cr, acrA, and acrB genes was done by polymerase chain reaction (PCR). In this study, fosfomycin and imipenem against E. coli and fosfomycin and tigecycline against K. pneumoniae had the best effect in antimicrobial susceptibility tests. PCR assay using specific primers demonstrated that the prevalence of qepA, aac(6')-Ib-cr, acrA, and acrB genes among the 100 E. coli isolates was 0 (0%), 87 (87%), 92 (92%), and 84 (84%), respectively. The prevalence of qepA, aac(6')-Ib-cr, acrA, and acrB genes among the 100 K. pneumoniae isolates was 4 (4%), 85 (85%), 94 (94%), and 87 (87%), respectively. The distribution of qepA, aac(6')-Ib-cr, acrA, and acrB resistance determinants in E. coli and K. pneumoniae is a great concern. Therefore, infection control and prevention of spread of drug-resistant bacteria need careful management of medication and identification of resistant isolates.

    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.

    Full Text Available Abstract Background Elevated circulating levels of C-reactive protein (CRP, interleukin (IL-6 and fibrinogen (FG have been repeatedly associated with many adverse outcomes in patients with chronic obstructive pulmonary disease (COPD. To date, it remains unclear whether and to what extent systemic inflammation is primary or secondary in the pathogenesis of COPD. The aim of this study was to examine the association between haplotypes of CRP, IL6 and FGB genes, systemic inflammation, COPD risk and COPD-related phenotypes (respiratory impairment, exercise capacity and body composition. Methods Eighteen SNPs in three genes, representing optimal haplotype-tagging sets, were genotyped in 355 COPD patients and 195 healthy smokers. Plasma levels of CRP, IL-6 and FG were measured in the total study group. Differences in haplotype distributions were tested using the global and haplotype-specific statistics. Results Raised plasma levels of CRP, IL-6 and fibrinogen were demonstrated in COPD patients. However, COPD population was very heterogeneous: about 40% of patients had no evidence of systemic inflammation (CRP CRP gene and CRP plasma levels (P = 0.0004 and IL6 gene and COPD (P = 0.003. Subsequent analysis has shown that IL6 haplotype H2, associated with an increased COPD risk (p = 0.004, OR = 4.82; 1.64 to 4.18, was also associated with very low CRP levels (p = 0.0005. None of the genes were associated with COPD-related phenotypes. Conclusion Our findings suggest that common genetic variation in CRP and IL6 genes may contribute to heterogeneity of COPD population associated with systemic inflammation.

    Respiratory tract infections are the most common indication for antibiotic prescribing in primary care. The value of clinical findings in lower respiratory tract infection (LRTI) is known to be overrated. This study aimed to determine the independent influence of a point of care test (POCT) for C-reactive protein (CRP) on the prescription of antibiotics in patients with acute cough or symptoms suggestive of LRTI, and how symptoms and chest findings influence the decision to prescribe when the test is and is not used. Prospective observational study of presentation and management of acute cough/LRTI in adults. Primary care research networks in Norway, Sweden, and Wales. Adult patients contacting their GP with symptoms of acute cough/LRTI. Predictors of antibiotic prescribing were evaluated in those tested and those not tested with a POCT for CRP using logistic regression and receiver operating characteristic (ROC) curve analysis. A total of 803 patients were recruited in the three networks. Among the 372 patients tested with a POCT for CRP, the CRP value was the strongest independent predictor of antibiotic prescribing, with an odds ratio (OR) of CRP ≥ 50 mg/L of 98.1. Crackles on auscultation and a patient preference for antibiotics perceived by the GP were the strongest predictors of antibiotic prescribing when the CRP test was not used. The CRP result is a major influence in the decision whether or not to prescribe antibiotics for acute cough. Clinicians attach less weight to discoloured sputum and abnormal lung sounds when a CRP value is available. CRP testing could prevent undue reliance on clinical features that poorly predict benefit from antibiotic treatment.

Considering the importance of those environments for the overall fish diversity in that river system,we surveyed the composition of the fish fauna of the upper portion of Purus River and two of its tributaries (Caeté andMacapá rivers, state of Acre, Brazil. The collections were done in November 2004, using a seine net and a set ofgillnets of different mesh sizes. A total of 735 specimens belonging to 86 species and 28 families were collected. Eightspecies, Creagrutus occidaneus, Phenacogaster pectinatus, Prionobrama filigera, Moenkhausia cf. lepidura,Leptagoniates pi (Characidade, Henonemus punctatus (Trichomycteridae, Toracocharax stellatus (Gateropelecidae,and Eigenmannia macrops (Sternopygidae composed nearly half of the specimens collected. This survey adds 48 newrecords to the ichthyofauna of Purus River and elevates to 243 the number of known fish species in that river, but agreater sampling effort is necessary to produce a reasonably complete picture of the fish diversity in the basin.

    In 1982, the American College of Radiology (ACR) and the National Electrical Manufacturers Association (NEMA) formed a committee to develop standards for the interconnection of digital imaging devices. Version 1.0 of the standard, published in 1985, specifies a hardware interface supporting point-to-point (not network) image transmission, a data dictionary (a set of rules for encoding information), and a set of commands to initiate transactions. Version 2.0, published in 1988, also addresses point-to-point image transmission and provides semantic rules by which messages (streams of bits representing information in transit from one device to another) are organized. Version 3.0, also referred to as DICOM (Digital Imaging and Communications in Medicine), will be finalized in 1992. The DICOM standard encourages open systems interconnection of imaging equipment over standard networks, while maintaining compatibility with earlier point-to-point connection standards. The DICOM standard conforms fully with the International Standards Organization reference model for network communications (ISORM), addresses the issue of conformance, and incorporates the concept of object-oriented design.

    The acute phase response (APR) is an early innate immune function that is initiated by inflammatory signals, leading to the release of acute phase proteins to the bloodstream to re-establish homeostasis following microbial infection. In this study we analysed the Atlantic salmon (Salmo salar) whole-genome database and identified five C-reactive protein (CRP)/serum amyloid P component (SAP) like molecules namely CRP/SAP-1a, CRP/SAP-1b, CRP/SAP-1c, CRP/SAP-2 and CRP/SAP-3. These CRP/SAP genes formed two distinct sub-families, a universal group (group I) present in all vertebrates and a fish/amphibian specific group (group II). Salmon CRP/SAP-1a, CRP/SAP-1b and CRP/SAP-1c and CRP/SAP-2 belong to the group I family whilst salmon CRP/SAP-3 is a member of group II. Gene expression analysis showed that the salmon CRP/SAP-1a as well as serum amyloid A-5 (SAA-5), one of the major acute phase proteins, were significantly up-regulated by recombinant cytokines (rIL-1β and rIFNγ) in primary head kidney cells whilst the other four CRP/SAPs remained refractory. Furthermore, SAA-5 was produced as the main acute phase protein (APP) in Atlantic salmon challenged with Aeromonas salmonicida (aroA(-) strain) whilst salmon CRP/SAPs remained unaltered. Overall, these data illustrate the potential different functions of expanded salmon CRP/SAPs to their mammalian homologues. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    In Denmark, patients with serious nonspecific symptoms and signs of cancer (NSSC) are referred to the diagnostic outpatient clinics (DOCs) where an accelerated cancer diagnostic program is initiated. Various immunological and inflammatory biomarkers have been associated with cancer, including soluble urokinase plasminogen activator receptor (suPAR) and the pattern recognition receptors (PRRs) pentraxin-3, mannose-binding lectin, ficolin-1, ficolin-2 and ficolin-3. We aimed to evaluate these biomarkers and compare their diagnostic ability to classical biomarkers for diagnosing cancer in patients with NSSC. Patients were included from the DOC, Department of Infectious Diseases, Copenhagen University Hospital Hvidovre. Patients were given a final diagnosis based on the combined results from scans, blood work and physical examination. Weight loss, Charlson score and previous cancer were registered on admission, and plasma concentrations of biomarkers were measured. The primary outcome was incident cancer within 1 year. Out of 197 patients included, 39 patients (19.8%) were diagnosed with cancer. Patients with cancer were significantly older and had a higher burden of comorbidities and previous cancer diagnoses compared to patients who were not diagnosed with cancer. Previous cancer, C-reactive protein (CRP) and suPAR were significantly associated with newly diagnosed cancer during follow-up in multiple logistic regression analyses adjusted for age, sex and CRP. Neither any of the PRRs investigated nor self-reported weight loss was associated with cancer. In this study, previous cancer, CRP and suPAR were significantly associated with cancer diagnosis in patients with NSSC. Ficolin-1-3, MBL and pentraxin-3 were not associated with cancer. © 2017 The Authors International Journal of Cancer published by John Wiley & Sons Ltd on behalf of Union for International Cancer Control.

    Full Text Available Clear cut-off levels could aid clinicians in identifying patients with a risk of fatal outcomes or complications such as deep infection foci in Staphylococcus aureus bacteremia (SAB. Cut-off levels for widely used clinical follow-up parameters including serum C-reactive protein (CRP levels and white blood cell counts (WBC have not been previously studied.430 adult SAB patients in Finland took part in prospective multicentre study in which their CRP levels and WBC counts were measured on the day of the positive blood culture, every other day during the first week, twice a week during hospitalization and at 30 days. Receiver operating characteristic (ROC analysis was used to evaluate the prognostic value of CRP and WBC on the day of the positive blood culture and at days 4, 7, and 14 in predicting mortality and the presence of deep infections at 30 days. Adjusted hazard ratios (HR for CRP level and WBC count cut-off values for mortality were calculated by the Cox regression analysis and adjusted odds ratios (OR for cut-off values to predict the presence of deep infection by the binary logistic regression analysis.The succumbing patients could be distinguished from the survivors, starting on day 4 after the positive blood culture, by higher CRP levels. Cut-off values of CRP for day 30 mortality in adjusted analysis, that significantly predicted fatal outcome were at day 4 CRP >103 mg/L with sensitivity of 77%, specificity of 55%, and HR of 3.5 (95% CI, 1.2-10.3; p = 0.024, at day 14 CRP >61 mg/L with a sensitivity of 82%, specificity of 80% and HR of 3.6 (95% CI, 1.1-10.3; p8.6 x109/L was prognostic with sensitivity of 77%, specificity of 78% and HR of 8.2 (95% CI, 2.9-23.1; p108 mg/L with sensitivity of 77%, specificity of 60%, and HR of 2.6 (95% CI, 1.3-4.9; p = 0.005 and at day 14 CRP >22 mg/L with sensitivity of 59%, specificity of 68%, and HR of 3.9 (95% CI, 1.6-9.5; p = 0.003.

    To evaluate the association of galectin-3 (Gal3) with obesity and inflammatory status in a cohort of metabolically healthy, predominantly African-American women with varying cardiovascular disease (CVD) risk as determined by CRP levels. We assessed the association between BMI and serum levels of Gal3, IL-6, CRP, and adiponectin in metabolically healthy women (N = 97) to determine the overall association between Gal3, obesity, and inflammation in groups at different CVD risk. Obese women had significantly higher serum Gal3 compared to non-obese participants (P = 0.0016), although Gal3 levels were comparable among different classes of obesity. BMI (R (2) = 0.1406, P = 0.0013), IL-6 (R (2) = 0.0689, P = 0.035), and CRP (R (2) = 0.0468, P = 0.0419), but not adiponectin, positively predicted the variance of Gal3 levels in the total study population. However, the predicting effect of BMI (R (2) = 0.2923, P = 0.0125) and inflammation (R (2) = 0.3138, P = 0.038) on Gal3 was only present in women at low/moderate risk of CVD (CRP ≤ 3 µg/mL). Gal3 is positively correlated with obesity and inflammation in women, while the presence of elevated CVD risk may disturb the strength of Gal3 as a biomarker of inflammation.

    Full Text Available Abstract The management of resectable rectal cancer continues to be guided by clinical trials and advances in technique. Although surgical advances including total mesorectal excision continue to decrease rates of local recurrence, the management of locally advanced disease (T3-T4 or N+ benefits from a multimodality approach including neoadjuvant concomitant chemotherapy and radiation. Circumferential resection margin, which can be determined preoperatively via MRI, is prognostic. Toxicity associated with radiation therapy is decreased by placing the patient in the prone position on a belly board, however for patients who cannot tolerate prone positioning, IMRT decreases the volume of normal tissue irradiated. The use of IMRT requires knowledge of the patterns of spreads and anatomy. Clinical trials demonstrate high variability in target delineation without specific guidance demonstrating the need for peer review and the use of a consensus atlas. Concomitant with radiation, fluorouracil based chemotherapy remains the standard, and although toxicity is decreased with continuous infusion fluorouracil, oral capecitabine is non-inferior to the continuous infusion regimen. Additional chemotherapeutic agents, including oxaliplatin, continue to be investigated, however currently should only be utilized on clinical trials as increased toxicity and no definitive benefit has been demonstrated in clinical trials. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every two years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer reviewed journals and the application of a well-established consensus methodology (modified Delphi to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to

    The ACR Commission on Human Resources conducts an annual electronic survey to better understand the present workforce scenario for radiologists. The Practice of Radiology Environment Database was used to identify group leads, who were asked to complete an electronic survey developed by the Commission on Human Resources. The survey asked group leads to report the number of radiologists they currently employ or supervise, the number hired in 2015, and the numbers they plan to hire in 2016 and 2019. Leaders were asked to report the subspecialty area used as the main reason for hiring each physician, as well the ages and genders of their current workforce. Thirty-two percent of group leaders, corresponding to 13,074 radiologists or 39% of all practicing radiologists, responded to this survey. The percentage of practicing radiologists who are male is 78.6%, compared with 21.4% who are female. Six percent of radiologists are older than 65 years, and 22% are between the ages of 56 and 65 years. Nineteen percent of radiologists older than 65 years retired in 2015. Fifteen percent of all radiologists work part-time. Among the part-time radiologists, 9% are male and 30% are female. General radiologists now make up only 13.3% of the radiologist workforce. In 2015, 45% of new hires moved from existing jobs; 55% were first-time hires. In 2016, it is projected that between 1,713 and 2,223 new jobs will be available, a 16.2% increase from hiring in 2015. Job opportunities for radiologists have continued to increase since 2013. Copyright © 2016. Published by Elsevier Inc.

    The ACR Commission on Human Resources continues to conduct its annual electronic survey to better understand the present workforce scenario for radiologists. The Practice of Radiology Environment Database was used to identify group leads, who were asked to complete an electronic survey developed by the Commission on Human Resources. The survey asked group leaders to report the number of radiologists they currently employ or supervise, the number hired in 2014, and the numbers they plan to hire in 2015 and 2018. The leaders were asked to report the subspecialty area used as the main reason for hiring each physician, as well as the ages and genders of their current workforce. Thirty-two percent of group leaders responded to the survey, corresponding to 12,079 radiologists or 39% of all practicing radiologists. Twenty-one percent of the workforce is female and 79% is male. Ten percent of radiologists older than 65 years are women, while 32% younger than 35 are women. Twelve percent of radiologists work part-time, corresponding to a breakdown of 10% of men and 24% of women working part-time. The current workforce is 13% general radiologists and 87% subspecialists. In 2015, a projected 1,131 to 1,484 jobs will be available for radiologists. Job opportunities for radiologists seem to be increasing compared with 2013 and are relatively similar to 2014. Radiologists continue to subspecialize in greater numbers, but only 39% of radiologists practice more than 50% of the time in their subspecialties. Copyright © 2015 American College of Radiology.

  12. New evidences for C-reactive protein (CRP deposits in the arterial intima as a cardiovascular risk factor

    Full Text Available Fabrizio Montecucco, François MachDivision of Cardiology, Foundation for Medical Research, University Hospital, Geneva, SwitzerlandAbstract: Inflammatory processes are orchestrated by several soluble molecules, which interact with cell populations involved. Cytokines, chemokines, acute-phase reactants, and hormones are crucial in the evolution of several inflammatory disorders, such as atherosclerosis. Several evidences suggest that C-reactive protein (CRP started to be considered as a cardiovascular risk factor, since CRP directly induces atheroslerosis development. The recent demonstration of CRP production not only by the liver, but also within atherosclerotic plaques by activated vascular cells, also suggests a possible dual role, as both a systemic and tissue agent. Although more studies are needed, some therapeutic approaches to reduce CRP levels have been performed with encouraging results. However, given the strong limitations represented by its low specificity and still accordingly with the American Heart Association, there is no need for high sensitivity CRP screening of the entire adult population as a public-health measure. The measure of serum CRP might be useful only for patients who are considered at intermediate risk.Keywords: atherosclerosis, inflammation, plaque, cardiovascular risk, C-reactive protein

    Depression has been associated with chronic changes in the serum concentration of C-reactive protein (CRP) in observational studies, but it is unclear if this association is causal or is due to confounding and bias. Genetic studies are less subject to this type of error and offer an opportunity to investigate if CRP is causally linked to depression, particularly because known polymorphisms of the CRP gene have been associated with high- and low-basal serum concentrations of CRP [single nucleotide polymorphisms (SNPs) rs1130864 and rs1205, respectively]. The aim of this study is to determine if polymorphisms of SNPs rs1130864 and rs1205 are associated with prevalent depression. We completed a cross-sectional study of a community sample of 3700 men aged > or = 70 years, and used the 15-item Geriatric Depression Scale (GDS-15) to assess depressive symptoms. A GDS-15 score 7 or more indicates the presence of clinically significant depressive symptoms. Physical morbidity was assessed with the physical component summary score (PCS) of the SF-36 Health Survey. We collected fasting blood samples to measure high sensitivity CRP and to extract DNA for the genotyping of SNPs rs1130864 and rs1205 of the CRP gene. One hundred and eighty-two men were depressed (4.9%). The odds of depression increased by 2% (95% CI = 1-4%) for every unit (mg/l) increase of CRP and nearly doubled for men with CRP > or = 3 mg/l vs or = 3 mg/l) and depression was no longer significant after the analyses were adjusted for smoking, age, body mass index (BMI) and PCS. Men with the CT and TT genotypes of rs1130864 had 1.36 (95% CI = 1.13-1.63) and 2.31 (95% CI = 1.65-3.24) greater odds of CRP > or = 3 mg/l than CC carriers, but there was no association between this polymorphism and the presence of prevalent depression. The G > A polymorphism of SNP rs1205 was associated with 24% (95% CI = 16-32%) lower concentration of CRP compared with other genotypes. Men with the rs1205 AA genotype had 1.66 (95% CI

    The aim of this study was to validate the 2013 ACR/EULAR classification criteria for systemic sclerosis (SSc) in patients with SSc, including patients with early SSc. Fifty-six consecutive patients with early SSc (2001 LeRoy and Medsger criteria), 122 patients with established SSc (1980 ACR classification criteria), and 141 patients with SSc-like disorders were included in this cross-sectional study. The diagnostic performance of the 2013 ACR/EULAR criteria was compared with the 1980 ACR criteria in several subsets of patients. The performance of individual variables was also obtained. Receiver operating characteristic (ROC) curves and optimal cut-off values were computed. The sensitivity and specificity in the whole cohort of 178 SSc patients were 77.6 and 98.5%, respectively, using the 2013 ACR/EULAR criteria and 68.5 and 100%, respectively, using the 1980 ACR criteria. Twenty-eight percent of the patients with early SSc met the 2013 ACR/EULAR criteria. Among the patients with early SSc, 53% of those who had Raynaud's phenomenon, abnormal capillaroscopy and positive SSc-related antibodies met the 2013 ACR/EULAR criteria. The area under the ROC curve was 0.975 (95% confidence interval 0.962-0.987). The best cut-off value for the total score was ≥8 (sensitivity 82%; specificity 97.9%). The individual variables with the highest specificity values were proximal skin thickening, sclerodactyly (specificity 100%), telangiectasia and SSc-related antibodies (specificity 98.6%). Raynaud's phenomenon had the best sensitivity (99.4%) but had low specificity (4.2%). In conclusion, the 2013 ACR/EULAR classification criteria showed high accuracy and increased sensitivity in the classification of patients with early SSc.

  17. Profound loss of neprilysin accompanied by decreased levels of neuropeptides and increased CRP in ulcerative colitis.

    Zeynep Gök Sargın

    Full Text Available Neprilysin (NEP, CD10 acts to limit excessive inflammation partly by hydrolyzing neuropeptides. Although deletion of NEP exacerbates intestinal inflammation in animal models, its role in ulcerative colitis (UC is not well explored. Herein, we aimed to demonstrate changes in NEP and associated neuropeptides at the same time in colonic tissue. 72 patients with UC and 27 control patients were included. Patients' demographic data and laboratory findings, five biopsy samples from active colitis sites and five samples from uninvolved mucosa were collected. Substance P (SP, calcitonin gene related peptide (CGRP and vasoactive intestinal peptide (VIP were extracted from freshly frozen tissues and measured using ELISA. Levels of NEP expression were determined using immunohistochemistry and immunoreactivity scores were calculated. GEBOES grading system was also used. We demonstrated a profound loss (69.4% of NEP expression in UC, whereas all healthy controls had NEP expression. Patients with UC had lower neuronal SP; however non-neuronal SP remained similar. UC patients had also lower neuronal and non-neuronal VIP levels. CGRP were low in general and no significant changes were observed. Additionally, CRP positive patients with UC had higher rates of NEP loss (80% vs 51.9% and lower SP levels when compared with CRP negative patients with UC. Concurrent decreases in SP and VIP with profound loss of NEP expression observed in UC is likely to be one of the factors in pathogenesis. Further studies are required to define the role of neuropeptides and NEP in UC.

    Full Text Available In order to study the influence of steering conditions to hybrid CRP podded propulsor,the calculation of the NACA0012 open-water rudder's lift coefficient was carried out by applying the RANS method combined with the SST k-ω turbulence model, and the near wall mesh arrangement and near wall treatment method applied in numerical calculation were selected through comparisons between the experimental results and the calculation results. The hydrodynamic performance of a podded propulsor was predicted on the basis of the above, and the calculation results showed a good agreement with the experimental results. The object of the research was a hybrid CRP podded propulsor, and its hydrodynamic performance in steering conditions was predicted by applying the numerical method above. Conclusions were drawn on the relationship between hydrodynamic performance parameters and steering angle, i.e. larger magnitudes of the after propeller thrust, pod horizontal force and steering moment will be acquired at larger steering angles, and the fore propeller thrust is basically as invariant as the pod steering. The internal reasons were also analyzed. Research shows that the propeller has good maneuverability,and will have wide application prospect.

    Purpose: A simple approach to investigate Interscanner variability of Radiomics features in computed tomography (CT) using a standard ACR phantom. Methods: The standard ACR phantom was scanned on CT scanners from three different manufacturers. Scanning parameters of 120 KVp, 200 mA were used while slice thickness of 3.0 mm on two scanners and 3.27 mm on third scanner was used. Three spherical regions of interest (ROI) from water, medium density and high density inserts were contoured. Ninety four Radiomics features were extracted using an in-house program. These features include shape (11), intensity (22), GLCM (26), GLZSM (11), RLM (11), and NGTDM (5) and 8 fractal dimensions features. To evaluate the Interscanner variability across three scanners, a coefficient of variation (COV) is calculated for each feature group. Each group is further classified according to the COV- by calculating the percentage of features in each of the following categories: COV less than 2%, between 2 and 10% and greater than 10%. Results: For all feature groups, similar trend was observed for three different inserts. Shape features were the most robust for all scanners as expected. 70% of the shape features had COV <2%. For intensity feature group, 2% COV varied from 9 to 32% for three scanners. All features in four groups GLCM, GLZSM, RLM and NGTDM were found to have Interscanner variability ≥2%. The fractal dimensions dependence for medium and high density inserts were similar while it was different for water inserts. Conclusion: We concluded that even for similar scanning conditions, Interscanner variability across different scanners was significant. The texture features based on GLCM, GLZSM, RLM and NGTDM are highly scanner dependent. Since the inserts of the ACR Phantom are not heterogeneous in HU values suggests that matrix based 2nd order features are highly affected by variation in noise.

    Full Text Available Objective. The effects of C-reactive protein (CRP and tumor necrosis factor-α (TNF-α on pregnancy-associated plasma protein-A (PAPP-A expression in human peripheral blood mononuclear cells (PBMCs require further investigation. Methods. The PAPP-A levels in culture supernatants, PAPP-A mRNA expression, and cellular PAPP-A expression were measured in human PBMCs isolated from fresh blood donations provided by 6 healthy volunteers (4 donations per volunteer. Analyses were conducted by ultrasensitive ELISA, western blotting, and RT-PCR following stimulation with CRP or TNF-α cytokines. Results. PAPP-A mRNA and protein levels after CRP stimulation peaked at 24 hours, whereas peak PAPP-A mRNA and protein levels were achieved after TNF-α stimulation at only 2 and 8 hours, respectively. These findings indicate the dose-dependent effect of CRP and TNF-α stimulation. Actinomycin D treatment completely prevented CRP and TNF-α induction of PAPP-A mRNA and protein expression. Additionally, nuclear factor- (NF- κB inhibitor (BAY11-7082 potently inhibited both CRP and TNF-α stimulated PAPP-A mRNA and protein expression. Conclusions. Human PBMCs are capable of expressing PAPP-A in vitro, expression that may be regulated by CRP and TNF-α through the NF-κB pathway. This mechanism may play a significant role in the observed increase of serum PAPP-A levels in acute coronary syndrome (ACS.

    Kawasaki disease (KD) is an acute self-limiting form of vasculitis that afflicts infants and children and manifests as fever and signs of mucocutaneous inflammation. Children with KD show various laboratory inflammatory abnormalities, such as elevations in their white blood cell (WBC) count, C-reactive protein (CRP) level, and erythrocyte sedimentation rate (ESR). We here performed a genome-wide association study (GWAS) of 178 KD patients to identify the genetic loci that influence 10 important KD laboratory markers: WBC count, neutrophil count, platelet count, CRP, ESR, hemoglobin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), albumin, and total protein. A total of 165 loci passed our arbitrary stage 1 threshold for replication (p SNP located at the CRP locus (rs12068753) demonstrated the most significant association with CRP in KD patients (beta = 4.73 and p = 1.20 × 10(-6) according to the stage 1 GWAS; beta = 3.65 and p = 1.35 × 10(-8) according to the replication study; beta = 3.97 and p = 1.11 × 10(-13) according to combined analysis) and explained 8.1% of the phenotypic variation observed. However, this SNP did not demonstrate any significant association with CRP in the general population (beta = 0.37 and p = 0.1732) and only explained 0.1% of the phenotypic variation in this instance. Furthermore, rs12068753 did not affect the development of coronary artery lesions or intravenous immunoglobulin resistance in KD patients. These results indicate that common variants in the CRP promoter can play an important role in the CRP levels in KD.

    Purpose/Objective(s): To assess the image quality of an integrated MR-Linac system and compare with other MRI systems that are primarily used for diagnostic purposes. Materials/Methods: An ACR MRI quality control (QC) phantom was used to evaluate the image quality of a fully integrated 1.5T MRI-Linac system recently installed at our institution. This system has a new split magnet design which gives the magnetic field strength of 1.5T. All images were acquired with a set of phased-array surface coils which are designed to have minimal attention of radiation beam. The anterior coil rests on a coil holder which keeps the anterior coil’s position consistent for QA purposes. The posterior coil is imbedded in the patient couch. Multiple sets of T1, T2/PD images were acquired using the protocols as prescribed by the ACR on three different dates, ranging 3 months apart. Results: The geometric distortion are within 0.5 mm in the axial scans and within 1mm in the saggital (z-direction) scans. Slice thickness accuracy, image uniformity, ghosting ratio, high contrast detectability are comparable to other 1.5T diagnostic MRI scanners. The low-contrast object detectability are lower comparatively, which is a result of using the body array coil. Additionally, the beam’s-eye-view images (oblique coronal and saggital images) have minimal geometric distortion at all linac gantry angles tested. No observable changes or drift in image quality is found from images acquired 3 month apart. Conclusion: Despite the use of a body array surface coil, the image quality is comparable to that of an 1.5T MRI scanner and is of sufficient quality to pass the ACR MRI accreditation program. The geometric distortion of the MRI system of the integrated MR-Linac is within 1mm for an object size similar to the ACR phantom, sufficient for radiation therapy treatment purpose. The authors received corporate sponsored research grants from Elekta which is the vendor for the MR-Linac evaluated in this

    Full Text Available A high sensitivity C-reactive protein to albumin ratio (hs-CRP/Alb predicts mortality risk in patients with acute kidney injury. However, it varies dynamically. This study was conducted to evaluate whether a variation of this marker was associated with long-term outcome in clinically stable hemodialysis (HD patients.hs-CRP/Alb was checked bimonthly in 284 clinically stable HD outpatients throughout all of 2008. Based on the "slope" of trend equation derived from 5-6 hs-CRP/alb ratios for each patient, the total number of patients was divided into quartiles--Group 1: β≦ -0.13, n = 71; group 2: β>-0.13≦0.003; n = 71, group 3: β>0.003≦0.20; and group 4: β>0.20, n = 71. The observation period was from January 1, 2009 to August 31, 2012.Group 1+4 showed a worse long-term survival (p = 0.04 and a longer 5-year hospitalization stay than Group 2+3 (38.7±44.4 vs. 16.7±22.4 days, p<0.001. Group 1+4 were associated with older age (OR = 1.03, 95% CI = 1.01-1.05 and a high prevalence of congestive heart failure (OR = 2.02, 95% CI = 1.00-4.11. Standard deviation (SD of hs-CRP/Alb was associated with male sex (β = 0.17, p = 0.003, higher Davies co-morbidity score (β = 0.16, p = 0.03, and baseline hs-CRP (β = 0.39, p<0.001. Patients with lower baseline and stable trend of hs-CRP/Alb had a better prognosis. By multivariate Cox proportional methods, SD of hs-CRP/alb (HR: 1.05, 95% CI: 1.01-1.08 rather than baseline hs-CRP/Alb was an independent predictive factor for long-term mortality after adjusting for sex and HD vintage.Clinically stable HD patients with a fluctuating variation of hs-CRP/Alb are characterized by old age, and more co-morbidity, and they tend to have longer subsequent hospitalization stay and higher mortality risk.

    Full Text Available ObjectiveTo evaluate the clinical effect of artificial liver support system (ALSS on serum high-sensitivity C-reactive protein (hs-CRP level and investigate the influence of the change in hs-CRP level on clinical prognosis among patients with hepatic failure. MethodsPatients were recruited into three groups: group one included 60 patients who received ALSS due to hepatic failure; group two included 37 patients with hepatic failure without ALSS treatment; and group three included 37 patients with chronic hepatitis B. The serum levels of hs-CRP were measured in groups two and three, and in group one before and after ALSS treatment. Comparison of continuous data between groups was made by t test, and comparison of categorical data was made by chi-square test. ResultsThe levels of hs-CRP in group one before treatment and in groups two and three were 12.89±9.39, 12.22±9.73, and 2.83±6.79, respectively. No significant difference in hs-CRP level between group one and group two was observed (P>0.05. However, the hs-CRP level in group three was significantly different from those in group one and group two (P<0.001. The improvement rate in group one after ALSS treatment (783% was significantly higher compared with that in group two (54.05% (χ2=6.315, P<0.05. ALSS treatment (t=5.179, P<0.05. ALSS treatment was selectively effective in a subgroup of patients and greatly decreased the hs-CRP level in these patients (t=5344,P=0.000), resulting in a significant difference from the patients who were unresponsive to ALSS treatment (t=2.368, P=0038. ConclusionArtificial liver support system can decrease the hs-CRP level in patients with hepatic failure. Serum level of hs-CRP can be used as a clinical indicator of disease progression and predict the clinical outcomes of ALSS in patients with hepatic failure.

    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

    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 intensive care Medicine was initiated in the State of the Acre in 1998. The aim of the present study was to establish clinical-epidemiological characteristics of adults and aged interned in a public intensive care unit (ICU) in the Amazon. In 2004, a prospective study evaluated patients interned through the application of a questionnaire containing socioeconomics variables, invasive procedures, mechanical ventilation, nutritional support, surgical interventions and dialitic treatment. The gravity was established by APACHE II applied after 24 hours of internment. The follow up continued until the final destination in the unit: discharge or death. The statistical analysis used program SPSS, considering differences significant when p UCI was of 10.2 ± 9.6 days; death occurred in 30 (38%) patients. Association between mortality and dialitic treatment, clinical indication, mechanical ventilation, vasoactive therapy, number of surgical interventions, hypoalbuminemia, lymphocytopenia and gravity was observed. The admission of severely ill patients coming from all over the State of Acre and frontier regions reflects the lack of ICU beds in the region.

  13. CRP and SAA1 Haplotypes Are Associated with Both C-Reactive Protein and Serum Amyloid A Levels: Role of Suppression Effects

    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.

    Objective High-sensitivity C-reactive protein (hsCRP) levels are closely associated with abdominal obesity, metabolic syndrome, and atherosclerotic cardiovascular disease. The JUPITER trial has encouraged using hsCRP ≥2 mg/L to guide statin therapy; however the association of hsCRP to atherosclerosis, independent of obesity, remains unknown. Methods and Results We studied 6,760 participants from the Multi-Ethnic Study of Atherosclerosis (MESA). Participants were stratified into 4 groups: non-obese/low hsCRP, non-obese/high hsCRP, obese/low hsCRP, and obese/high hsCRP. Using multivariable logistic and robust linear regression, we described the association with subclinical atherosclerosis, using coronary artery calcium (CAC) and carotid intima-media thickness (cIMT). Mean BMI was 28.3 ± 5.5 kg/m2, and median hsCRP was 1.9 mg/L (0.84 – 4.26). High hsCRP, in the absence of obesity, was not associated with CAC and was mildly associated with cIMT. Obesity was strongly associated with CAC and cIMT independent of hsCRP. When obesity and high hsCRP were both present, there was no evidence of multiplicative interaction. Similar associations were seen among 2,083 JUPITER-eligible individuals. Conclusions High hsCRP, as defined by JUPITER, was not associated with CAC and was mildly associated with cIMT in the absence of obesity. In contrast, obesity was associated with both measures of subclinical atherosclerosis independent of hsCRP status. PMID:21474823

    The benchmark consists of 4 phases starting from the local standalone modeling (Phase I) to the safety calculation of coupled system with transient situation (Phase IV). 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.

    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.

  19. Comparison of Homogeneous and Heterogeneous CFD Fuel Models for Phase I of the IAEA CRP on HTR Uncertainties Benchmark

    2014-04-01

    Computational Fluid Dynamics (CFD) evaluation of homogeneous and heterogeneous fuel models was performed as part of the Phase I calculations of the International Atomic Energy Agency (IAEA) Coordinate Research Program (CRP) on High Temperature Reactor (HTR) Uncertainties in Modeling (UAM). This study was focused on the nominal localized stand-alone fuel thermal response, as defined in Ex. I-3 and I-4 of the HTR UAM. The aim of the stand-alone thermal unit-cell simulation is to isolate the effect of material and boundary input uncertainties on a very simplified problem, before propagation of these uncertainties are performed in subsequent coupled neutronics/thermal fluids phases on the benchmark. In many of the previous studies for high temperature gas cooled reactors, the volume-averaged homogeneous mixture model of a single fuel compact has been applied. In the homogeneous model, the Tristructural Isotropic (TRISO) fuel particles in the fuel compact were not modeled directly and an effective thermal conductivity was employed for the thermo-physical properties of the fuel compact. On the contrary, in the heterogeneous model, the uranium carbide (UCO), inner and outer pyrolytic carbon (IPyC/OPyC) and silicon carbide (SiC) layers of the TRISO fuel particles are explicitly modeled. The fuel compact is modeled as a heterogeneous mixture of TRISO fuel kernels embedded in H-451 matrix graphite. In this study, a steady-state and transient CFD simulations were performed with both homogeneous and heterogeneous models to compare the thermal characteristics. The nominal values of the input parameters are used for this CFD analysis. In a future study, the effects of input uncertainties in the material properties and boundary parameters will be investigated and reported.

  1. Sialic acid transport and catabolism are cooperatively regulated by SiaR and CRP in nontypeable Haemophilus influenzae

    2010-09-01

    Full Text Available Abstract Background The transport and catabolism of sialic acid, a critical virulence factor for nontypeable Haemophilus influenzae, is regulated by two transcription factors, SiaR and CRP. Results Using a mutagenesis approach, glucosamine-6-phosphate (GlcN-6P was identified as a co-activator for SiaR. Evidence for the cooperative regulation of both the sialic acid catabolic and transport operons suggested that cooperativity between SiaR and CRP is required for regulation. cAMP was unable to influence the expression of the catabolic operon in the absence of SiaR but was able to induce catabolic operon expression when both SiaR and GlcN-6P were present. Alteration of helical phasing supported this observation by uncoupling SiaR and CRP regulation. The insertion of one half-turn of DNA between the SiaR and CRP operators resulted in the loss of SiaR-mediated repression of the transport operon while eliminating cAMP-dependent induction of the catabolic operon when GlcN-6P was present. SiaR and CRP were found to bind to their respective operators simultaneously and GlcN-6P altered the interaction of SiaR with its operator. Conclusions These results suggest multiple novel features for the regulation of these two adjacent operons. SiaR functions as both a repressor and an activator and SiaR and CRP interact to regulate both operons from a single set of operators.

    Patients on chronic hemodialysis or peritoneal dialysis often develop an inflammatory state that causes morbidity and mortality. Cross-sectional studies of dialysis patients have determined that C-reactive protein (CRP) is a predictor of morbidity. Little is known as to whether CRP, cytokines, such as IL-6 and IL-1beta that stimulate the synthesis of CRP, or matrix metalloproteinases (MMPs) are markers of inflammation in patients on dialysis. We assayed by ELISA serum levels of MMP-2, MMP-3, IL-6 and CRP in healthy individuals and in patients with pre-end-stage renal disease (pESRD, n = 10), peritoneal dialysis (PD, n = 11), hemodialysis (HD, n = 17) and renal transplant (TX, n = 10). MMP-2 was significantly elevated before dialysis, perhaps indicative of progressive chronic renal sclerosis. MMP-3 was markedly elevated in hemodialysis patients but not in pESRD or PD patients, and may be related to the hemodialysis process and/or accelerated atherogenesis in these patients. IL-6 was significantly elevated in all patient groups, including pESRD patients. There were no statistically significant differences in CRP levels among the study groups. CRP correlated with IL-6, but not with MMP-2 or MMP-3. The data indicate that there are measurable differences in the expression of MMPs within the dialysis patient population. Because dialysis can be associated with local and systemic inflammation, increased levels of MMP-3 in the hemodialysis group may be a reflection of gene stimulation induced by inflammatory cytokines and should be considered as a marker of chronic, local inflammation.

    Population-based studies have associated inflammation, particularly higher C-reactive protein (CRP), with depressive severity, but clinical trials in major depressive disorder were rather non-specific without examining the role of gender. We aimed to investigate the association between CRP and overall depression severity including specific depressive symptoms and to examine potential gender differences. We included 231 individuals with major depressive disorder from the Genome-Based Therapeutics Drugs for Depression (GENDEP) study. At baseline, we assessed high-sensitivity CRP levels and psychopathology with the Montgomery Aasberg Depression Rating Scale (MADRS). We performed linear regression analyses to investigate the association between baseline CRP levels with overall MADRS severity and specific symptoms at baseline and adjusted for age, gender, anti-inflammatory and psychotropic drug treatment, body mass index, smoking, inflammatory diseases, and recruitment center. Higher CRP levels were significantly associated with greater overall MADRS symptom severity (p=0.02), which was significant among women (p=0.02) but not among men (p=0.68). Among women, higher CRP was associated with increased severity on observed mood, cognitive symptoms, interest-activity, and suicidality, but we found no significant associations among men. Interaction analyses showed no significant gender differences on the overall MADRS score or specific symptoms. Our results support the sickness syndrome theory suggesting that chronic low-grade inflammation may be associated with a subtype of depression. The potential gender differences in psychopathology may be explained by biological and/or psychosocial factors, e.g. differential modulation of immune responses by sex hormones. Clinical studies should investigate symptom-specific and/or gender-specific treatment guided by peripheral inflammatory markers. Copyright © 2017 Elsevier Inc. All rights reserved.

    Type 1 fimbriae are a crucial factor for the virulence of uropathogenic Escherichia coli during the first steps of infection by mediating adhesion to epithelial cells. They are also required for the consequent colonization of the tissues and for invasion of the uroepithelium. Here, we studied the role of the specialized signal transduction system CRP-cAMP in the regulation of type 1 fimbriation. Although initially discovered by regulating carbohydrate metabolism, the CRP-cAMP complex controls a major regulatory network in Gram-negative bacteria, including a broad subset of genes spread into different functional categories of the cell. Our results indicate that CRP-cAMP plays a dual role in type 1 fimbriation, affecting both the phase variation process and fimA promoter activity, with an overall repressive outcome on fimbriation. The dissection of the regulatory pathway let us conclude that CRP-cAMP negatively affects FimB-mediated recombination by an indirect mechanism that requires DNA gyrase activity. Moreover, the underlying studies revealed that CRP-cAMP controls the expression of another global regulator in Gram-negative bacteria, the leucine-responsive protein Lrp. CRP-cAMP-mediated repression is limiting the switch from the non-fimbriated to the fimbriated state. Consistently, a drop in the intracellular concentration of cAMP due to altered physiological conditions (e.g. growth in presence of glucose) increases the percentage of fimbriated cells in the bacterial population. We also provide evidence that the repression of type 1 fimbriae by CRP-cAMP occurs during fast growth conditions (logarithmic phase) and is alleviated during slow growth (stationary phase), which is consistent with an involvement of type 1 fimbriae in the adaptation to stress conditions by promoting biofilm growth or entry into host cells. Our work suggests that the metabolic sensor CRP-cAMP plays a role in coupling the expression of type 1 fimbriae to environmental conditions, thereby

  8. Lack of AcrB Efflux Function Confers Loss of Virulence on Salmonella enterica Serovar Typhimurium

    2017-07-01

    Full Text Available AcrAB-TolC is the paradigm resistance-nodulation-division (RND multidrug resistance efflux system in Gram-negative bacteria, with AcrB being the pump protein in this complex. We constructed a nonfunctional AcrB mutant by replacing D408, a highly conserved residue essential for proton translocation. Western blotting confirmed that the AcrB D408A mutant had the same native level of expression of AcrB as the parental strain. The mutant had no growth deficiencies in rich or minimal medium. However, compared with wild-type SL1344, the mutant had increased accumulation of Hoechst 33342 dye and decreased efflux of ethidium bromide and was multidrug hypersusceptible. The D408A mutant was attenuated in vivo in mouse and Galleria mellonella models and showed significantly reduced invasion into intestinal epithelial cells and macrophages in vitro. A dose-dependent inhibition of invasion was also observed when two different efflux pump inhibitors were added to the wild-type strain during infection of epithelial cells. RNA sequencing (RNA-seq revealed downregulation of bacterial factors necessary for infection, including those in the Salmonella pathogenicity islands 1, 2, and 4; quorum sensing genes; and phoPQ. Several general stress response genes were upregulated, probably due to retention of noxious molecules inside the bacterium. Unlike loss of AcrB protein, loss of efflux function did not induce overexpression of other RND efflux pumps. Our data suggest that gene deletion mutants are unsuitable for studying membrane transporters and, importantly, that inhibitors of AcrB efflux function will not induce expression of other RND pumps.

    The goal of this study is to compare the overall quality of film mammograms taken according to the Korean standards with the American College of Radiology (ACR) standard for clinical image evaluation and to identify means of improving mammography quality in Korea. Four hundred and sixty eight sets of film mammograms were evaluated with respect to the Korean and ACR standards for clinical image evaluation. The pass and failure rates of mammograms were compared by medical facility types. Average scores in each category of the two standards were evaluated. Receiver operating characteristic curve analysis was used to identify an optimal Korean standard pass mark by taking the ACR standard as the reference standard. 93.6% (438/468) of mammograms passed the Korean standard, whereas only 80.1% (375/468) passed the ACR standard (p < 0.001). Non-radiologic private clinics had the lowest pass rate (88.1%: Korean standard, 71.8%: ACR standard) and the lowest total score (76.0) by the Korean standard. Average scores of positioning were lowest (19.3/29 by the Korean standard and 3.7/5 by the ACR standard). A cutoff score of 77.0 for the Korean standard was found to correspond to a pass level when the ACR standard was applied. We suggest that tighter regulations, such as, raising the Korean pass mark, subtracting more for severe deficiencies, or considering a very low scores in even a single category as failure, are needed to improve the quality of mammography in Korea.

    Full Text Available Abstract Background Most bacteria can use various compounds as carbon sources. These carbon sources can be either co-metabolized or sequentially metabolized, where the latter phenomenon typically occurs as catabolite repression. From the practical application point of view of utilizing lignocellulose for the production of biofuels etc., it is strongly desirable to ferment all sugars obtained by hydrolysis from lignocellulosic materials, where simultaneous consumption of sugars would benefit the formation of bioproducts. However, most organisms consume glucose prior to consumption of other carbon sources, and exhibit diauxic growth. It has been shown by fermentation experiments that simultaneous consumption of sugars can be attained by ptsG, mgsA mutants etc., but its mechanism has not been well understood. It is strongly desirable to understand the mechanism of metabolic regulation for catabolite regulation to improve the performance of fermentation. Results In order to make clear the catabolic regulation mechanism, several continuous cultures were conducted at different dilution rates of 0.2, 0.4, 0.6 and 0.7 h-1 using wild type Escherichia coli. The result indicates that the transcript levels of global regulators such as crp, cra, mlc and rpoS decreased, while those of fadR, iclR, soxR/S increased as the dilution rate increased. These affected the metabolic pathway genes, which in turn affected fermentation result where the specific glucose uptake rate, the specific acetate formation rate, and the specific CO2 evolution rate (CER were increased as the dilution rate was increased. This was confirmed by the 13C-flux analysis. In order to make clear the catabolite regulation, the effect of crp gene knockout (Δcrp and crp enhancement (crp+ as well as mlc, mgsA, pgi and ptsG gene knockout on the metabolism was then investigated by the continuous culture at the dilution rate of 0.2 h-1 and by some batch cultures.

    Numerous studies document environmental and social benefits of the Conservation Reserve Program (CRP). This report offers a synopsis of findings regarding effects of establishing CRP conservation practices on the quality and distribution of wildlife habitat in agricultural landscapes. On individual farms, year-round provision of wildlife habitat by the CRP may appear relatively insignificant. However, considered from multi-farm to National scales, such improvements in habitat and wildlife response have proven to be extensive and profound.

    The AcrAB-TolC efflux pump is involved in maintaining intrinsic organic solvent tolerance in Escherichia coli. Mutations in regulatory genes such as marR, soxR, and acrR are known to increase the expression level of the AcrAB-TolC pump. To identify these mutations in organic solvent tolerant E. coli, eight cyclohexane-tolerant E. coli JA300 mutants were isolated and examined by DNA sequencing for mutations in marR, soxR, and acrR. Every mutant carried a mutation in either marR or acrR. Among all mutants, strain CH7 carrying a nonsense mutation in marR (named marR109) and an insertion of IS5 in acrR, exhibited the highest organic solvent-tolerance levels. To clarify the involvement of these mutations in improving organic solvent tolerance, they were introduced into the E. coli JA300 chromosome by site-directed mutagenesis using λ red-mediated homologous recombination. Consequently, JA300 mutants carrying acrR::IS5, marR109, or both were constructed and named JA300 acrRIS, JA300 marR, or JA300 acrRIS marR, respectively. The organic solvent tolerance levels of these mutants were increased in the following order: JA300 marR marR. JA300 acrRIS marR formed colonies on an agar plate overlaid with cyclohexane and p-xylene (6:4 vol/vol mixture). The organic solvent-tolerance level and AcrAB-TolC efflux pump-expression level in JA300 acrRIS marR were similar to those in CH7. Thus, it was shown that the synergistic effects of mutations in only two regulatory genes, acrR and marR, can significantly increase organic solvent tolerance in E. coli.

    DAS28 is a widely used composite score for the assessment of disease activity in patients with rheumatoid arthritis (RA) and is often used as a treatment decision tool in the daily clinic. Different versions of DAS28 are available. DAS28-CRP(3) is calculated based on three variables: swollen...... and tender joint counts and CRP. DAS28-CRP(4) also includes patient global assessment. Thresholds for low and high disease activity are the same for the two scores. Based on the Bland-Altman method, the interchangeability between DAS28-CRP with three and four variables was examined in 319 RA patients...

  15. The association of C-reactive protein and CRP genotype with coronary heart disease: findings from five studies with 4,610 cases amongst 18,637 participants.

    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.

    Systemic sclerosis (SSc) is a well-established disease associated with primary biliary cholangitis (PBC). However, the original 1980 American College of Rheumatology (ACR) criteria have poor sensitivity, especially for the detection of earlier SSc in previous studies. The objective was to evaluate the prevalence of SSc in patients with PBC using more sensitive 2001 LeRoy and Medsger criteria and the 2013 ACR/European League Against Rheumatism (EULAR) classification criteria. The secondary objective was to evaluate the frequency of individual clinical features. One hundred consecutive patients with PBC without previously diagnosed SSc were recruited between 2005 and 2007 from a tertiary care gastroenterology clinic. All patients underwent a complete clinical examination, determination of SSc-specific antibodies, and a nailfold capillary microscopy. Fulfillment of the 3 different criteria sets was analyzed, along with individual disease features. Of 100 patients with PBC, 1% met the ACR 1980 criteria, 22% met the 2001 LeRoy and Medsger criteria for early SSc, and 17% the 2013 ACR/EULAR criteria. Raynaud phenomenon, SSc-related antibodies, and SSc capillaroscopic patterns were the most prevalent findings, with the highest sensitivities to help guide future screening. Our data show a high prevalence of SSc in patients with PBC with probable underestimation by previous studies using the original ACR criteria. Comorbid SSc should be actively searched for based on newly described criteria to improve detection and increase benefits of earlier treatment.

    Glutamine synthetase (GS) is an important enzyme for nitrogen assimilation, and GS2, encoded by GLN2, is the only plastid-type GS in Arabidopsis thaliana. A co-expression analysis suggested that the expression level of the gene encoding a uridylyltransferase-like protein, ACR11, is strongly correlated with GLN2 expression levels. Here we showed that the recombinant ACR11 protein increased GS2 activity in vitro by reducing the Km values of its substrate glutamine. A T-DNA insertion mutant of ACR11 exhibited a reduced GS activity under low nitrate conditions and reduced glutamine levels. Biochemical analyses revealed that ACR11 and GS2 interacted both in vitro and in vivo. These data demonstrate that ACR11 is an activator of GS2, giving it a mechanistic role in the nitrogen assimilation of A. thaliana. © The Author 2017.

    Right cardiac pathologies develop in patients with obstructive sleep apnea syndrome (OSAS) and in most patients there are no symptoms in the early stages of right cardiac disorders. We aimed to evaluate a possible relationship between B-type natriuretic peptide (BNP), blood uric acid, C-reactive protein (CRP), and the right cardiac pathologies in patients with OSAS, and the role of these parameters in the management of patients with OSAS. A total of 98 subjects, 31 (31.6%) controls and 67 (68.4%) with OSAS, were included in the study. All the subjects underwent polysomnography, and standard and tissue Doppler echocardiography (ECHO) examinations. BNP, CRP, and blood uric acid levels were measured in all patients. Upon evaluating the relationship between BNP and ECHO parameters, BNP levels were found to positively correlate with such ECHO parameters as pulmonary artery pressure. As for the association between CRP and ECHO findings, RV diameter exhibited a statistically significant positive correlation with them. Moreover, uric acid was found to statistically correlate positively with right atrium dimensions. BNP, CRP, and blood uric acid levels can be used as adjunctive parameters in the early diagnosis and follow-up of right heart pathologies in patients with OSAS.

    Microglia are involved in immune surveillance in intact brains and become activated in response to inflammation and neurodegeneration. Microglia have different functions, neuroprotective or neurotoxic, according to aging in patients with PD. The clinical effect of microglia in patients with Alzheimer's disease (AD) is poorly defined. This prospective study was conducted to investigate the clinical effects of microglia according to the aging process in newly diagnosed AD. We examined 532 patients with newly diagnosed AD and 119 healthy controls, and the differences in hs-CRP between these groups were investigated. The patients with AD were classified into 3 subgroups according to age of newly diagnosed AD to investigate the relationship between hs-CRP and the aging process in newly diagnosed AD. There was significantly higher serum high-sensitivity C-reactive protein (hs-CRP), levels in patients with AD compared with healthy controls. A post-hoc analysis of the 3 AD subgroups showed no significant differences in serum hs-CRP level between each group. We assumed that neuroinflammation play a role in the pathogenesis of AD, but found no clinical evidence that microglia senescence underlies the microglia switch from neuroprotective in young brains to neurotoxic in aged brains. To clarify the role of microglia and aging in the pathogenesis of AD, future longitudinal studies involving a large cohort are required.

    The aim of this study was to determine whether neutrophil CD64 (nCD64) combined with procalcitonin (PCT), C-reactive protein (CRP) and white blood cell count (WBC) can increase the sensitivity and accuracy of neonatal sepsis diagnosis. The serum levels of nCD64, CRP, PCT and WBC were detected in 60 patients with neonatal sepsis and 60 patients with non-sepsis. Sensitivity, specificity, positive and negative predictive values, receiver operating characteristic (ROC) area under the curve (AUC), and logistic regression analysis were performed to evaluate the diagnostic value of these markers on neonatal sepsis. Serum levels of nCD64, PCT, CRP and WBC were higher in the sepsis group than non-sepsis group (pneonatal sepsis were increased to 95.5%. Except for WBC, the birth weight and gestational age had no effects on the diagnostic value of these serum biomarkers. nCD64 and PCT are better diagnostic biomarkers for early diagnosis of neonatal sepsis as compared to CRP. With the help of optimal cut-off value based on ROC curve and logistic regression analysis, the combination of these biomarkers could improve the sensitivity for the diagnosis of suspected late-onset neonatal sepsis based on common serum biomarkers.

    Full Text Available Background: Nowadays, stroke can be considered as the one of the major causes of disability and mortality worldwide. However, relationship between serum C-reactive protein (CRP level with stroke early prognosis has not been well studied, especially in Iran. Therefore, the present study aimed to study the relationship between CRP level of serum in patients with acute stroke at first 24h of admission and stroke early prognosis. Methods: This prospective cross-sectional study was performed on 50 patients with acute stroke who were admitted at Emergency Ward of Shahid Rajaie Hospital, in Tonekabon City, Iran, between May 2013 to July 2014. In first step, valid clinical diagnosis was made based on CT scan and magnetic resonance imaging (MRI of the patients. The ethical observations were considered for all patients. The serum level of CRP was measured by standard method, at first 24h of the admission. Clinical information and risk factors (age, gender, type of stroke, high blood pressure, diabetes mellitus was detected for each patient. On discharge, early prognosis by modified Rankin Scale (mRS (mRS< 3= good and mRS≥ 3= bad was also recognized. In this study, statistical analysis was performed using SPSS software, and logistic regression method was used (P< 0.05. Results: The results of this study showed that 38% of the patients were 70-80 years old. Also, 52% of the patients were male and 48% were female. The serum CRP level of patients at the first 24h of admission increased in all studied patients. The mean of the serum CRP level was 12.82 that were higher than the normal range. The statistical analysis showed that there was no significant relationship between the serum CRP level and the stroke early prognosis. Conclusion: Although the serum CRP level was not recognized as an anticipator factor for stroke prognosis at this study, it is recommended to performance of more studies by case-study method on this setting.

  5. Structures of Gate Loop Variants of the AcrB Drug Efflux Pump Bound by Erythromycin Substrate.

    2016-01-01

    Gram-negative bacteria such as E. coli use tripartite efflux pumps such as AcrAB-TolC to expel antibiotics and noxious compounds. A key feature of the inner membrane transporter component, AcrB, is a short stretch of residues known as the gate/switch loop that divides the proximal and distal substrate binding pockets. Amino acid substitutions of the gate loop are known to decrease antibiotic resistance conferred by AcrB. Here we present two new AcrB gate loop variants, the first stripped of its bulky side chains, and a second in which the gate loop is removed entirely. By determining the crystal structures of the variant AcrB proteins in the presence and absence of erythromycin and assessing their ability to confer erythromycin tolerance, we demonstrate that the gate loop is important for AcrB export activity but is not required for erythromycin binding.

    Full Text Available The ACRE (ACtive REhabilitation robotic device is developed to enhance therapeutic treatment of upper limbs after stroke. The aim of this study is to assess effects and costs of ACRE training for frail elderly patients and to establish if ACRE can be a valuable addition to standard therapy in nursing home rehabilitation. The study was designed as randomized controlled trial, one group receiving therapy as usual and the other receiving additional ACRE training. Changes in motor abilities, stroke impact, quality of life and emotional well-being were assessed. In total, 24 patients were included. In this small number no significant effects of the ACRE training were found. A large number of 136 patients were excluded. Main reasons for exclusion were lack of physiological or cognitive abilities. Further improvement of the ACRE can best be focused on making the system suitable for self-training and development of training software for activities of daily living.

    Morbid obesity (MO) is associated with an increase in circulating levels of systemic acute phase proteins such as C-reactive protein (CRP). Toll-like receptor is possible candidate for inflammatory responses which is mainly mediated by NFKB1. The aim of this study was to investigate the relationship between NFKB1 and Toll-like receptor (TLR) 2 polymorphisms and the risk of MO in a Turkish population in the context of CRP serum levels which may contribute to susceptibility to the disease. We analysed the distribution of NFKB1-94 ins/del ATTG rs28362491 and TLR2 Arg753Gln rs5743708 polymorphisms using PCR-RFLP method and CRP serum levels using ELISA method in 213 MO and 200 healthy controls. The frequency of the ins/ins genotype and ins allele of rs28362491 was significantly higher in the patients compared to control group (P: 0.0309; P: 0.0421, respectively). Additionally, the frequency of GG genotype and G allele of rs5743708 was found to be statistically higher in the patient group (P: 0.0421; P 20 mg/l) in MO patients with ins/ins genotype were significantly higher than in patients with del/ins genotype (P: 0.0309). Serum CRP levels were also higher in MO patients with GG genotype and G allele (P: 0.0001). According to combined analysis, the wild type of rs28362491 and rs5743708 polymorphisms (ins/ins/GG genotype) was also significantly higher in the patient group versus the control group when compared with the combined ins/ins/GA and del/ins/GA genotype (P < 0.0001). Therefore, our findings suggest that rs28362491 and rs5743708 polymorphisms were significantly associated with MO disease through acting by modulating serum CRP levels. © 2016 The Foundation for the Scandinavian Journal of Immunology.

    In this study, we aimed to evaluate two cardiovascular risk markers, hs-CRP and visseral adiposity index, in patients with policystic ovary syndrome in association with clinical and laboratory findings. Study group included 75 patients who were diagnosed as PCOS according to the criteria of AE-PCOS 2006 and control group included 75 non-PCOS patients who were subsequently admitted to outpatient clinic for smear control, with urinary or vaginal symptoms. Physical and sonographic examinations were made to all subjects. Mean arterial pressure, waist/hip ratio and body mass index were calculated. Fasting blood glucose and insulin, HbA1c, lipids, high sensitivity C-reactive protein (hs-CRP), estradiol, follicle stimulating hormon, luteinising hormone, tiroid stimulating hormone, prolaktin, total testosteron and sex hormone binding globulin were tested in venous blood samples collected from cases following overnight fast in follicular phase of spontaneous or induced menstruation. Visceral adiposity index was also calculated. No statistically significant difference was found between PCOS group and control group concerning hs-CRP and VAI (p>0.05). When patients in PCOS group were further grouped as obese and non-obese, hs-CRP and VAI values in obese group were significantly higher than those in non-obese group (p0.05), VAI values were significantly higher in obese control group (p<0.05). According to the results of our study, hs-CRP stands for a better and more specific marker than VAI to determine metabolic components and predictive risks for cardiovascular diseases in patients with PCOS. Further studies with larger populations are needed in order to determine cardiovascular risks particularly in young PCOS patients. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Lymph node status is a key indicator of the best approach to treatment of invasive breast cancer. However, the accuracy with which lymph node metastasis is diagnosed is not currently satisfactory. New and more reliable methods that enable one to know who has a greater potential for lymph node metastasis would be highly desirable. We previously reported that lymph node involvement in esophageal and lung cancer may have a genetic component: C-reactive protein (CRP) 1846C>T genetic polymorphism. Here we examined the diagnostic value of CRP 1846C>T polymorphism for assessing the risk of lymph node metastasis in cases of invasive breast cancer. The study participants were 185 women with invasive breast cancer who underwent curative surgery with lymph node dissection. Using DNA from blood samples and polymerase chain reaction-restriction fragment length polymorphism, the utility of CRP genetic 1846C>T polymorphism (rs1205) for assessing the risk of lymph node metastasis was evaluated. Fifty-two (28 %) patients had lymph node metastasis. After the patients were divided into two groups based on their CRP 1846 genotypes (C/C+C/T and T/T), the clinical characteristics did not differ between the groups, but there was a significantly greater incidence of lymph node metastasis among patients in the T/T group. Moreover, the odds ratio for lymph node involvement in patients carrying the 1846 T/T genotype was more than 2.2 in multivariate logistic regression models. CRP genetic polymorphism may be a novel predictor of the risk of lymph node metastasis in invasive breast cancer.

    Image-guided radiation therapy using cone-beam computed tomography (CBCT) is becoming routine practice in modern radiation therapy. The purpose of this work was to develop an imaging QA program for CT and CBCT units in our department, based on the American College of Radiology (ACR) CT accreditation phantom. The phantom has four testing modules, permitting one to test CT number accuracy, slice width, low contrast resolution, image uniformity, in-plane distance accuracy, and high-contrast resolution reproducibly with suggested window/levels for image analysis. Additional tests for contrast-to-noise ratio (CNR) and noise were added using the polyethylene and acrylic plugs. Baseline values were obtained from CT simulator images acquired on a Phillips Brilliance Big Bore CT simulator and CBCT images acquired on three Varian CBCTs for the imaging protocols most used clinically. Images were then acquired quarterly over a period of two years. Images were exported via DICOM and analyzed manually using OsiriX. Baseline values were used to ensure that image quality remained consistent quarterly, and baselines were reset at any major maintenance or recalibration. Analysis of CT simulator images showed that image quality was within ACR guidelines for all tested scanning protocols. All three CBCT systems were unable to distinguish the low-contrast resolution plugs and had the same high-contrast resolution over all imaging protocols. Analysis of CBCT results over time determined a range of values that could be used to establish quantitative tolerance levels for image quality deterioration. While appropriate for the helical CT, the ACR phantom and guidelines could be modified to be more useful in evaluating CBCT systems. In addition, the observed values for the CT simulator were well within ACR tolerances.

    Southwestern Amazonia, where Bolivia, Brazil and Peru meet, faces numerous challenges to the sustainable utilization of land and water resources as the region experiences rapid population and economic growth, expanding agriculture, transportation and energy sectors, along with frequent flooding and droughts. It is also predicted to be one of the most susceptible areas for climate change in the coming decade. The Acre River Basin, one of the few trinational basins in Amazonia, lies at the center of the Madre de Dios Region (Peru), Acre State (Brazil) and Pando Department (Bolivia) or MAP Region. It covers approximately 7,500 km2 and its inhabitants range from indigenous groups avoiding contact with industrial society to more than 60,000 dwellers of a binational urban center. The basin incorporates most the challenges facing the region and this paper discusses steps underway to address the basin's vulnerability to climate-related threats. A trinational group of professionals used GIS databases and local knowledge to classify these threats and possible societal responses. To prioritize threats and to propose responses, this group adapted a method proposed by the Queensland Climate Change Centre of Excellence of Australia to develop climate risk matrices for assessing impacts, adaptation, risk and vulnerability. The three priority climate variables were prolonged and more frequent droughts, more intense flooding, and more days with temperatures > 35oC. The final matrix proposed two areas of concentration - 1) Reduce the vulnerability of communities to hydro-meteorological extreme events and 2) Protect and restore ecosystems that maintain critical water-related resources with actions in public policy, capacity-building, and immediate activities. These results are being incorporated into the Amazon Project of the Global Environment Fund of the United Nations Environment Program, administered by the Amazon Cooperation Treaty Organization (ACTO).

  14. Association of the C-Reactive Protein Gene (CRP rs1205 C>T Polymorphism with Aortic Valve Calcification in Patients with Aortic Stenosis

    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.

    2015-05-01

    Full Text Available Background: Low circulating IGF-1 and high hs-CRP may be associated with cardiovascular diseases. Hence, it is an important question that is there any correlation between these important biomarkers? Since the correlation between IGF-1 and hs-CRP has not been adequately investigated, the main aim of this study was to evaluate the association between these biomarkers among postmenopausal women. Materials and Methods: A total of 361 healthy Iranian postmenopausal women were randomly selected in a population-based study. The metabolic syndrome was defined according to NCEP, ATPIII criteria. Circulating hs-CRP and IGF-1 levels were measured by highly specific enzyme-linked immunosorbent assay method. Results: Women with higher than median hs-CRP levels had lower IGF-1 levels, in comparison to women with lower than median hs-CRP levels (p<0.0001. In multiple regression analysis, after adjustment for age and the metabolic syndrome, IGF-1 levels had a significant inverse correlation with circulating hs-CRP levels (β=-0.139, p<0.007. After adjustment for age, body mass index and type 2 diabetes mellitus, IGF-1 levels also showed an inverse correlation with hs-CRP levels (β=-0.130, p<0.014. Conclusion: There is a significant inverse correlation between serum IGF-1 and hs-CRP levels in postmenopausal women. This finding provides evidence of the potential cardioprotective effect of IGF-1 via anti-inflammatory mechanisms.

    An accurate molecular diagnosis of diabetes subtype confers clinical benefits; however, many individuals with monogenic diabetes remain undiagnosed. Biomarkers could help to prioritise patients for genetic investigation. We recently demonstrated that high-sensitivity C-reactive protein (hs......CRP) levels are lower in UK patients with hepatocyte nuclear factor 1 alpha (HNF1A)-MODY than in other diabetes subtypes. In this large multi-centre study we aimed to assess the clinical validity of hsCRP as a diagnostic biomarker, examine the genotype-phenotype relationship and compare different hsCRP assays....... High-sensitivity CRP levels were analysed in individuals with HNF1A-MODY (n = 457), glucokinase (GCK)-MODY (n = 404), hepatocyte nuclear factor 4 alpha (HNF4A)-MODY (n = 54) and type 2 diabetes (n = 582) from seven European centres.

    2014-12-01

    The Conservation Reserve Program (CRP) is a USDA program administered by the Farm Service Agency (FSA) introduced in 1985 to reduce soil erosion by increasing vegetative cover of highly erodible land. The Texas High Plains (THP) leads the US with >890,000 ha enrolled in CRP. Potential benefits of the CRP include, e.g., increased infiltration of rainfall and organic matter, and better soil structure. However, impact of these benefits is not well characterized. Participation in the CRP is done via contracts (10-15 years in length) and since its inception land area of the THP enrolled in CRP has varied significantly allowing the evaluation of years of enrollment (age) on soil structure and impact on rain infiltration. This information is critical for land users to determine how long it is necessary to enroll their land in the CRP to improve soil structure and impact rain infiltration and increase the water holding capacity of the soil. Stable isotopes of water present a useful technique that is used in ecology and hydrology to study water movement through ecosystems and can be used to evaluate the depth of infiltration of rainwater under CRP management. We compared the infiltration depth of rain in land under CRP management to land under continuous dryland cotton with no irrigation. Two locations, in Terry and Lynn counties, were used for this study. The site in Terry County was enrolled in CRP for 25 years (1985) and 22 years (1992) in Lynn County.

    Full Text Available Introduction: Atherogenic lipid profile is an important risk factor in development of atherosclerosis in menopausal women. High level of small dense LDL, that is more susceptible to oxidation, and high levels of inflammatory markers are also associated with an increased risk for development of atherosclerosis. Objective. The aim of this study was to investigate the relationship between lipid profile, oxidized LDL (Ox-LDL and C-reactive protein (CRP as inflammatory reaction in healthy women dependent on age and menopause. Method. The study included a group of clinically healthy women (total of 97 women. Group 1: 15 women younger than 45 years; group 2: 62 women between 46 and 55 years, group 3: 20 women between 56 and 65 years, group of menopausal women (73 and group of premenopausal women (24. None of the women had history of obesity, diabetes mellitus, cerebrovascular, ischaemic heart disease, and hypertension. Lipid profiles were measured by enzymatic methods. Ox-LDL was measured by using a specific monoclonal antibody, mAb4E6. CRP was measured using hemiluminiscent methods (Immulite-DPC. Results. Results showed significantly higher levels of total cholesterol (p<0.01 and LDL cholesterol (p<0.01 in women over 56 years compared with women younger than 45 years. We also found similar results in menopausal women. Levels of Ox-LDL (p<0.05 and CRP (p<0.01 showed significantly higher levels in women over 56 years. In menopausal women, we found significantly higher levels of CRP (p<0.05. There was no significant difference in the levels of oxLDL between the menopausal and premenopausal women. Levels of triglycerides and HDL cholesterol were not different among groups. We found that 51% women had levels of HDL cholesterol lower than 1.3 mmol/L. In all groups of women, we found positive correlation among age, Ox-LDL (p<0.01 and CRP (p<0.01. Ox-LDL also positively correlated with CRP (p<0.01. Conclusion. In healthy women older than 56 as in menopausal

    Recent studies offer contradictory findings about the role of multidrug efflux pumps in bacterial biofilm development. Thus, the aim of this study was to investigate the involvement of the AcrAB efflux pump in biofilm formation by investigating the ability of AcrB and AcrAB null mutants of Salmonella enterica serovar Typhimurium to produce biofilms. Three models were used to compare the ability of S. Typhimurium wild-type and its mutants to form biofilms: formation of biofilm on polystyrene surfaces; production of biofilm (mat model) on the air/liquid interface; and expression of curli and cellulose on Congo red-supplemented agar plates. All three investigated genotypes formed biofilms with similar characteristics. However, upon exposure to chloramphenicol, formation of biofilms on solid surfaces as well as the production of curli were either reduced or were delayed more significantly in both mutants, whilst there was no visible effect on pellicle formation. It can be concluded that when no selective pressure is applied, S. Typhimurium is able to produce biofilms even when the AcrAB efflux pumps are inactivated, implying that the use of efflux pump inhibitors to prevent biofilm formation is not a general solution and that combined treatments might be more efficient. Other factors that affect the ability to produce biofilms depending on efflux pump activity are yet to be identified. Copyright © 2015 Elsevier B.V. and the International Society of Chemotherapy.

  3. Functional rotation of the transporter AcrB: insights into drug extrusion from simulations.

    Directory of Open Access Journals (Sweden)

    2010-06-01

    Full Text Available The tripartite complex AcrAB-TolC is the major efflux system in Escherichia coli. It extrudes a wide spectrum of noxious compounds out of the bacterium, including many antibiotics. Its active part, the homotrimeric transporter AcrB, is responsible for the selective binding of substrates and energy transduction. Based on available crystal structures and biochemical data, the transport of substrates by AcrB has been proposed to take place via a functional rotation, in which each monomer assumes a particular conformation. However, there is no molecular-level description of the conformational changes associated with the rotation and their connection to drug extrusion. To obtain insights thereon, we have performed extensive targeted molecular dynamics simulations mimicking the functional rotation of AcrB containing doxorubicin, one of the two substrates that were co-crystallized so far. The simulations, including almost half a million atoms, have been used to test several hypotheses concerning the structure-dynamics-function relationship of this transporter. Our results indicate that, upon induction of conformational changes, the substrate detaches from the binding pocket and approaches the gate to the central funnel. Furthermore, we provide strong evidence for the proposed peristaltic transport involving a zipper-like closure of the binding pocket, responsible for the displacement of the drug. A concerted opening of the channel between the binding pocket and the gate further favors the displacement of the drug. This microscopically well-funded information allows one to identify the role of specific amino acids during the transitions and to shed light on the functioning of AcrB.

    CANDU (Canadian Deuterium Uranium) is a type of reactor that uses heavy water (D{sub 2}O) as a moderator and as a refrigerant. Despite having chemical characteristics similar to light water (H{sub 2}O), heavy water has a high moderation ratio for neutrons. This feature enables CANDU to use natural uranium as fuel. However, research has evaluated the possibility of using H{sub 2}O as a refrigerant and D{sub 2}O as a moderator aiming at reducing the volume of heavy water. Such changes would imply the use of lightly enriched uranium due to the presence of H{sub 2}O. In this context, the concept of ACR (Advanced CANDU Reactor) has been developed. This reactor has an innovative design which combines of the current CANDU with the characteristics of PWR (Pressurized Water Reactor) type reactors. Studies by AECL (Atomic Energy Canada Limited) show that compared to CANDU, the ACR presents a cost reduction in construction, improved firing performance, improved operation safety and longer life. The present work aims to evaluate, in steady state, some of the main neutron parameters of CANDU-6 and ACR-1000. The MCNPX 2.6.0 code (Monte Carlo N-Particle eXtended -version 2.6.0) was used to simulate such types of reactors. The results show that the models configured in the MCNPX adequately reproduce the neutron behavior of the studied reactors. These models may be used in future work for analysis of fuel burn and evolution.

    Full Text Available Este trabalho teve como objetivo avaliar a qualidade de castanhas-do-brasil beneficiadas e comercializadas em Rio Branco, Acre. Foram analisadas amostras das três marcas de castanha encontradas no mercado local quanto às variáveis: atividade de água, teor de umidade, contagem total de fungos filamentosos, quantificação de Aspergillus flavus e de A. parasiticus, bem como quantificação de aflatoxinas B1, B2, G1 e G2. As castanhas do comércio se encontravam com um teor de umidade e atividade de água adequados, o que pode ter sido responsável pela baixa contaminação por fungos e por aflatoxinas. Quanto a estas micotoxinas, as amostras estão de acordo com o recomendado pela Anvisa, podendo ser esta uma consequência da grande divulgação no Estado do uso de Boas Práticas no manejo da castanha.The goal of this paper was to evaluate the quality of Brazil nuts processed and marketed in the city of Rio Branco, in the state of Acre (Brazil. We analysed three samples for water activity, moisture content, total fungus quantification of Aspergillus flavus and A. parasiticus, as well as quantification of total aflatoxin, Afla B1, Afla B2, Afla G1 and Afla G2. The nut samples from the market showed an appropriate moisture content and water activity, which may have been responsible for the low fungus contamination and aflatoxin production. As to these mycotoxins, the samples were consistent with Anvisa's recommendations, which may be a consequence of good management of the nuts in Acre.

    The thermonuclear rate of the 46Cr(p ,γ )47Mn reaction has been determined using a newly evaluated proton separation energy of Sp(47Mn) =380 ±30 keV and nuclear structure information from the mirror nucleus 47Ti. The astrophysical impact of this new rate and previously available rates has been investigated through one-zone postprocessing type-I x-ray burst calculations. The present 46Cr(p ,γ )47Mn rate leads to a mass fraction at A =46 that is 60 times larger than that obtained using a statistical model rate. The new results constrain the calculated maximum and minimum mass fractions at A =46 and A =48 to be within factors of 12 and 4, respectively. Experimental studies of the level structure of 47Mn near the proton threshold are required to improve these model predictions.

    This study was designed to assess the effects of Dietary Approaches to Stop Hypertension (DASH) eating plan on insulin resistance and serum hs-CRP in overweight and obese women with PCOS. This randomized controlled clinical trial was done on 48 women diagnosed with PCOS. Subjects were randomly assigned to consume either the control (n=24) or the DASH eating pattern (n=24) for 8 weeks. The DASH diet consisted of 52% carbohydrates, 18% proteins, and 30% total fats. It was designed to be rich in fruits, vegetables, whole grains, and low-fat dairy products and low in saturated fats, cholesterol, refined grains, and sweets. Sodium content of the DASH diet was designed to be less than 2 400 mg/day. The control diet was also designed to contain 52% carbohydrates, 18% protein, and 30% total fat. Fasting blood samples were taken at baseline and after 8 weeks intervention to measure -insulin resistance and serum hs-CRP levels. -Adherence to the DASH eating pattern, compared to the -control diet, resulted in a significant reduction of serum insulin levels (-1.88 vs. 2.89 μIU/ml, p=0.03), HOMA-IR score (-0.45 vs. 0.80; p=0.01), and serum hs-CRP levels (-763.29 vs. 665.95 ng/ml, p=0.009). Additionally, a significant reduction in waist (-5.2 vs. -2.1 cm; p=0.003) and hip circumference (-5.9 vs. -1 cm; pPCOS resulted in the improvement of insulin resistance, serum hs-CRP levels, and abdominal fat accumulation. www.irct.ir: IRCT201304235623N6. © Georg Thieme Verlag KG Stuttgart · New York.

    2014-01-01

    Full Text Available Background: Inflammatory mechanisms appear to play a major role in pathogenesis of various types of pulmonary hypertension such as idiopatic PAH (iPAH. Although inflammatory factors such as IL6 and TNFa play an important role in IPAH, there is limited information about the relationship between acute phase reactants and pulmonary hypertension occurring secondary to pulmonary diseases such as chronic obstructive pulmonary diseases (COPD. Methods: This cross-sectional study was carried out on 94 patients with COPD. Patients with a recent history of systemic corticosteroid use, infection, trauma or surgery, and gastrointestinal bleeding were excluded. Body plethysmography and transthoracic echocardiography were performed. Blood samples were taken from all patients and sent for complete blood count (CBC and hsCRP tests. Results: Twenty patients (28.6% had pulmonary hypertension. There was a significant difference between the mean of WBC in patients with and without pulmonary hypertension (8505 mic/lit vs. 7044 mic/lit (p=0.04. There was also a significant difference between the hs.CRP in patients with and without pulmonary hypertension (8.8pg/ml vs. 4.07pg/ml (p=0.032. After adjustment of age, sex, serum hemoglobin, hematocrit, O2sat, FEV1 and FVC, the relationship between the IL6, white blood cell count, HS.CRP and pulmonary hypertension remained significant (p=0.018, p=0.022. Conclusion: Inflammatory factors such as white blood cell and HS.CRP are independent risk factors of pulmonary hypertension in COPD patients.

    Experimental Chagas disease has been used as a model to identify several host/parasite interaction factors involved in immune responses to Trypanosoma cruzi infection. One of the factors inherent to this parasite is the complement regulatory protein (Tc-CRP), a major epitope that induces production of lytic antibodies during T. cruzi infections. Previous studies have evaluated the function of Tc-CRP as an antigenic marker via ELISAs, which demonstrated high sensitivity and specificity when compared to other methods. Therefore, this study aimed to assess and compare the levels of lytic antibodies induced by this protein following experimental infection using different T. cruzi strains. Our results demonstrated that infections induced by strains isolated from vectors resulted in subpatent parasitaemia and low reactivity, as assessed by Tc-rCRP ELISAs. On the other hand, mice inoculated with T. cruzi strains isolated from patients developed patent parasitaemia, and presented elevated lytic antibodies titres, as measured by Tc-rCRP ELISA. In addition, comparison between different mouse lineages demonstrated that Balb/c mice were more reactive than C57BL/6 mice in almost all types of infections, except those infected by the AQ-4 strain. Parasites from the Hel strain generated the greatest lytic antibody response in all evaluated models. Therefore, application of sensitive techniques for monitoring immune responses would enable us to establish growth curves for lytic antibodies during the course of the infection, and allow us to discriminate between T. cruzi strains that originate from different hosts.

    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.

    Full Text Available 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

    Long-term exposures to particulate matter air pollution (PM2.5 and PM10) and high traffic load have been associated with markers of systemic inflammation. Epidemiological investigations have focused primarily on total PM, which represents a mixture of pollutants originating from different sources. We investigated associations between source-specific PM and high-sensitive C-reactive protein (hs-CRP), an independent predictor of cardiovascular disease. We used data from the first (2000-2003) and second examination (2006-2008) of the Heinz Nixdorf Recall study, a prospective population-based German cohort of initially 4,814 participants (45-75 years of age). We estimated residential long-term exposure to local traffic- and industry-specific fine particulate matter (PM2.5) at participants' residences using a chemistry transport model. We used a linear mixed model with a random participant intercept to estimate associations of source-specific PM and natural log-transformed hs-CRP, controlling for age, sex, education, body mass index, low- and high-density lipoprotein cholesterol, smoking variables, physical activity, season, humidity, and city (8,204 total observations). A 1-μg/m3 increase in total PM2.5 was associated with a 4.53% increase in hs-CRP concentration (95% CI: 2.76, 6.33%). hs-CRP was 17.89% (95% CI: 7.66, 29.09%) and 7.96% (95% CI: 3.45, 12.67%) higher in association with 1-μg/m3 increases in traffic- and industry-specific PM2.5, respectively. RESULTS for PM10 were similar. Long-term exposure to local traffic-specific PM (PM2.5, PM10) was more strongly associated with systemic inflammation than total PM. Associations of local industry-specific PM were slightly stronger but not significantly different from associations with total PM.

    The purpose of this study is to evaluate the ability of cardio-ankle vascular index (CAVI), high-sensitivity C-reactive protein (hs-CRP) levels and homocysteine (Hcy) levels to screen for subclinical arteriosclerosis (subAs) in an apparently healthy population, with the view to obtaining an optimal diagnostic marker or profile for subAs. Subjects (152) undergoing routine health examinations were recruited and divided into two groups: carotid arteriosclerosis (CA) and non-carotid arteriosclerosis (NCA), according to carotid intima-media thickness (CMIT). CAVI was calculated based on blood pressure and pulse wave velocity. Serum hs-CRP and Hcy levels were also measured. A Receiver Operating Characteristic (ROC) curve was plotted to evaluate the efficacy of each in carotid arteriosclerosis screening. Ten parameter combinations, designated W1 to W10, were compared in terms of sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). The levels of all three parameters were significantly higher in the CA group, compared with the NCA group. ROC curves showed that the area under the curve (AUC) for CAVI was 0.708 (95%CI: 0.615-0.800), which is significantly larger than that of either hs-CRP (0.622) or Hcy (0.630), respectively (P < 0.001). Maximum sensitivity (100%) and NPV (100%) were attained with W10, while maximum specificity (86.2%) and PPV (46.7%) were obtained with W7. With W9, the maximum Youden index (0.416) was obtained, with a sensitivity of 77.8% and specificity of 63.8%. CAVI is more effective than hs-CRP or Hcy for subAs screening. The optimal profile was obtained with a combination of CAVI and other parameters.

    The CSRP2 gene encoding the LIM domain protein CRP2 was originally identified in quail based on its strong transcriptional suppression in transformed avian fibroblasts. Here we have isolated a human CSRP2 cDNA clone encoding a 193-amino-acid human CRP2 (hCRP2) protein with 96.4% amino acid sequence identity to the avian homolog. The CSRP2 cDNA clone was used to isolate CSRP2-related clones from gamma EMBL3 and P1 libraries of human genomic DNA. The complete organization of the CSRP2 gene was determined by nucleic acid hybridization, transcriptional mapping, and nucleotide sequence analysis. The gene spans a total of approximately 22 kb and contains six exons. The coding region is confined to exons 2-6 and predicts a hCRP2 protein identical in its amino acid sequence to the protein deduced from the CSRP2 cDNA clone. By fluorescence in situ hybridization using both lambda EMBL3 and P1 library clones as hybridization probes and a new method for computerized signal localization, CSRP2 was mapped to chromosome subband 12q21.1, a region frequently affected by deletion or breakage events in various tumor types. The library screens also led to the isolation of a CSRP2-related pseudogene, CSRP2P, which carried several extensive deletions and nucleotide substitutions but no intervening sequences in comparison to the CSRP2 cDNA sequence. By physical linkage and fluorescence in situ hybridization, CSRP2P was mapped to chromosome subband 3q21.1.

    Study included 20 patients with diagnosis of fascial space infections of odontogenic origin to assess efficacy of serum CRP levels as monitoring tools for determining severity of infections, hospital stay and efficacy of treatment. Blood samples taken on Day 0, 4 and 8 for measuring serum levels of marker. Simultaneously clinical parameters like swelling size, pain etc. were also recorded on Day 0, 4 and 8 and appropriate treatment given to each patient. Correlation between markers and parameters was found using regression and paired t-test. Statistical analysis found strong correlation between lab. values of markes and parameters used to measure severity of infection. Also CRP is significant marker for hospital stay (P<.01). Prospective analysis indicates CRP can be effective marker for determining severity of infection, treatment efficacy and hospital stay. Duration of antibiotic usage, intensive unit care, use of nutritional supplements becomes more rationale. Markers also make treatment cost effective and help protecting patients from side effects of excess drug usage.

  1. Improving acetate tolerance of Escherichia coli by rewiring its global regulator cAMP receptor protein (CRP.

    Directory of Open Access Journals (Sweden)

    Full Text Available The presence of acetate exceeding 5 g/L is a major concern during E. coli fermentation due to its inhibitory effect on cell growth, thereby limiting high-density cell culture and recombinant protein production. Hence, engineered E. coli strains with enhanced acetate tolerance would be valuable for these bioprocesses. In this work, the acetate tolerance of E. coli was much improved by rewiring its global regulator cAMP receptor protein (CRP, which is reported to regulate 444 genes. Error-prone PCR method was employed to modify crp and the mutagenesis libraries (~3×10(6 were subjected to M9 minimal medium supplemented with 5-10 g/L sodium acetate for selection. Mutant A2 (D138Y was isolated and its growth rate in 15 g/L sodium acetate was found to be 0.083 h(-1, much higher than that of the control (0.016 h(-1. Real-time PCR analysis via OpenArray(® system revealed that over 400 CRP-regulated genes were differentially expressed in A2 with or without acetate stress, including those involved in the TCA cycle, phosphotransferase system, etc. Eight genes were chosen for overexpression and the overexpression of uxaB was found to lead to E. coli acetate sensitivity.

    Proteobacteria often co-ordinate responses to carbon sources using CRP and the second messenger cyclic 3', 5'-AMP (cAMP), which combine to control transcription of genes during growth on non-glucose substrates as part of the catabolite-repression response. Here we show that cAMP-CRP is active and important in Vibrio fischeri during colonization of its host squid Euprymna scolopes. Moreover, consistent with a classical role in catabolite repression, a cAMP-CRP-dependent reporter showed lower activity in cells grown in media amended with glucose rather than glycerol. Surprisingly though, intracellular cAMP levels were higher in glucose-grown cells. Mutant analyses were consistent with predictions that CyaA was responsible for cAMP generation, that the EIIA(Glc) component of glucose transport could enhance cAMP production and that the phophodiesterases CpdA and CpdP consumed intracellular and extracellular cAMP respectively. However, the observation of lower cAMP levels in glycerol-grown cells seemed best explained by changes in cAMP export, via an unknown mechanism. Our data also indicated that cAMP-CRP activity decreased during growth on glucose independently of crp's native transcriptional regulation or cAMP levels. We speculate that some unknown mechanism, perhaps carbon-source-dependent post-translational modulation of CRP, may help control cAMP-CRP activity in V.fischeri. © 2015 John Wiley & Sons Ltd.

    Full Text Available Background: This study aimed to evaluate the risk markers of Coronary Artery Disease (CAD, so that appropriate lifestyle changes can be instituted early to prevent or delay development of the disease.. Objectives: This study aimed to evaluate the risk markers of CAD based on inflammation and arterial morphology; i.e., high sensitivity C-Reactive Protein (hs-CRP and carotid artery Intima Media Thickness (IMT, in children of patients with premature CAD.. Patients and Methods: This was a case-control study with predetermined end points. It was conducted on 40 subjects randomly selected from the children of premature CAD patients and 40 age- and sex-matched healthy controls. Blood levels of hs-CRP, lipid profile, and carotid IMT were assessed for all the subjects. The relationship among these parameters was evaluated by univariate and multivariate analyses using the SPSS statistical software, version 22.0 and P < 0.05 was considered as statistically significant.. Results: The mean values of Total Cholesterol (TC, 139.8 ± 24 vs. 111.3 ± 14.7, P < 0.05, Triglycerides (TG, 81.8 ± 15.3 vs. 63.4 ± 10.8, P < 0.05, Low Density Lipoprotein (LDL, 85.2 ± 22.2 vs. 57.5 ± 14.1, P < 0.05, hs-CRP (1.2 ± 0.77 vs. 0.79 ± 0.27, P < 0.05 and carotid artery IMT (0.49 ± 0.09 vs. 0.422 ± 0.03, P < 0.05 were significantly higher in the cases compared to the controls. Also, both LDL/High Density Lipoprotein (HDL and TC/HDL ratios were significantly higher in the cases compared to the controls. Moreover, a significant positive correlation was found between carotid IMT and hs-CRP.. Conclusions: Children of patients with premature CAD showed a significantly higher incidence of dyslipidemia as well as significantly increased levels of the inflammation marker, hs- CRP, compared to the age- and sex-matched controls. This indicates that atherosclerosis is not only a disease of lipid deposition, but also an inflammatory process. This was further confirmed by

  5. Expression of the AcrAB Components of the AcrAB-TolC Multidrug Efflux Pump of Yersinia enterocolitica Is Subject to Dual Regulation by OmpR.

    Directory of Open Access Journals (Sweden)

    Adrianna Raczkowska

    Full Text Available OmpR is a transcriptional regulator implicated in the control of various cellular processes and functions in Enterobacteriaceae. This study was undertaken to identify genes comprising the OmpR regulon in the human gastrointestinal pathogen Yersinia enterocolitica. Derivatives of an ompR-negative strain with random transposon insertions creating transcriptional fusions with the reporter gene lacZ were isolated. These were supplied with the wild-type ompR allele in trans and then screened for OmpR-dependent changes in β-galactosidase activity. Using this strategy, five insertions in genes/operons positively regulated by OmpR and two insertions in genes negatively regulated by this protein were identified. Genetic analysis of one of these fusion strains revealed that the gene acrR, encoding transcriptional repressor AcrR is negatively regulated by OmpR. Differential analysis of membrane proteins by SDS-PAGE followed by mass spectrometry identified the protein AcrB, a component of the AcrAB-TolC multidrug efflux pump, as being positively regulated by OmpR. Analysis of the activity of the acrR and acrAB promoters using gfp fusions confirmed their OmpR-dependent repression and activation, respectively. The identification of putative OmpR-binding sites and electrophoretic mobility shift assays confirmed that this regulator binds specifically to both promoter regions with different affinity. Examination of the activity of the acrR and acrAB promoters after the exposure of cells to different chemicals showed that bile salts can act as an OmpR-independent inducer. Taken together, our findings suggest that OmpR positively controls the expression of the AcrAB-TolC efflux pump involved in the adaptive response of Y. enterocolitica O:9 to different chemical stressors, thus conferring an advantage in particular ecological niches.

    Microorganisms can be engineered for the production of chemicals utilized in the polymer industry. However many such target compounds inhibit microbial growth and might correspondingly limit production levels. Here, we focus on compounds that are precursors to bioplastics, specifically styrene and representative alpha-olefins; 1-hexene, 1-octene, and 1-nonene. We evaluated the role of the Escherichia coli efflux pump, AcrAB-TolC, in enhancing tolerance towards these olefin compounds. AcrAB-TolC is involved in the tolerance towards all four compounds in E. coli. Both styrene and 1-hexene are highly toxic to E. coli. Styrene is a model plastics precursor with an established route for production in E. coli (McKenna and Nielsen, 2011). Though our data indicates that AcrAB-TolC is important for its optimal production, we observed a strong negative selection against the production of styrene in E. coli. Thus we used 1-hexene as a model compound to implement a directed evolution strategy to further improve the tolerance phenotype towards this alpha-olefin. We focused on optimization of AcrB, the inner membrane domain known to be responsible for substrate binding, and found several mutations (A279T, Q584R, F617L, L822P, F927S, and F1033Y) that resulted in improved tolerance. Several of these mutations could also be combined in a synergistic manner. Our study shows efflux pumps to be an important mechanism in host engineering for olefins, and one that can be further improved using strategies such as directed evolution, to increase tolerance and potentially production. © 2015 Wiley Periodicals, Inc.

    Control of nematode parasite infections relies largely on anthelmintic drugs, several of which act on nicotinic ACh receptors (nAChRs), and there are concerns about the development of resistance. There is an urgent need for development of new compounds to overcome resistance and novel anthelmintic drug targets. We describe the functional expression and pharmacological characterization of a homomeric nAChR, ACR-16, from a nematode parasite. Using RT-PCR, molecular cloning and two-electrode voltage clamp electrophysiology, we localized acr-16 mRNA in Ascaris suum (Asu) and then cloned and expressed acr-16 cRNA in Xenopus oocytes. Sensitivity of these receptors to cholinergic anthelmintics and a range of nicotinic agonists was tested. Amino acid sequence comparison with vertebrate nAChR subunits revealed ACR-16 to be most closely related to α7 receptors, but with some striking distinctions. acr-16 mRNA was recovered from Asu somatic muscle, pharynx, ovijector, head and intestine. In electrophysiological experiments, the existing cholinergic anthelmintic agonists (morantel, levamisole, methyridine, thenium, bephenium, tribendimidine and pyrantel) did not activate Asu-ACR-16 (except for a small response to oxantel). Other nAChR agonists: nicotine, ACh, cytisine, 3-bromocytisine and epibatidine, produced robust current responses which desensitized at a rate varying with the agonists. Unlike α7, Asu-ACR-16 was insensitive to α-bungarotoxin and did not respond to genistein or other α7 positive allosteric modulators. Asu-ACR-16 had lower calcium permeability than α7 receptors. We suggest that ACR-16 has diverse tissue-dependent functions in nematode parasites and is a suitable drug target for development of novel anthelmintic compounds. © 2016 The Authors.

    Arsenic (As) is a toxic carcinogen so it is crucial to decrease As accumulation in crops to reduce its risk to human health. Arsenite (AsIII) antiporter ACR3 protein is critical for As metabolism in organisms, but it is lost in flowering plants. Here, a novel ACR3 gene from As-hyperaccumulator Pteris vittata, PvACR3;1, was cloned and expressed in Saccharomyces cerevisiae (yeast), Arabidopsis thaliana (model plant), and Nicotiana tabacum (tobacco). Yeast experiments showed that PvACR3;1 functioned as an AsIII-antiporter to mediate AsIII efflux to an external medium. At 5 μM AsIII, PvACR3;1 transgenic Arabidopsis accumulated 14-29% higher As in the roots and 55-61% lower As in the shoots compared to WT control, showing lower As translocation. Besides, transgenic tobacco under 5 μM AsIII or AsV also showed similar results, indicating that expressing PvACR3;1 gene increased As retention in plant roots. Moreover, observation of PvACR3;1-green fluorescent protein fusions in transgenic Arabidopsis showed that PvACR3;1 protein localized to the vacuolar membrane, indicating that PvACR3;1 mediated AsIII sequestration into vacuoles, consistent with increased root As. In addition, soil experiments showed ∼22% lower As in the shoots of transgenic tobacco than control. Thus, our study provides a potential strategy to limit As accumulation in plant shoots, representing the first report to decrease As translocation by sequestrating AsIII into vacuoles, shedding light on engineering low-As crops to improve food safety.

    We previously reported that Klebsiella pneumoniae MGH78578 exhibited higher resistance against various antimicrobials than K. pneumoniae ATCC10031. In this study, we showed that the plasmid, pKPN5 in K. pneumoniae MGH78578 played an important role in resistance against aminoglycosides, ampicillin, tetracycline, and chloramphenicol, while genome-derived ß-lactamases and drug efflux pumps appeared to be more important in resistance to cloxacillin. acrAB, encoding a potent multidrug efflux pump, was cloned from K. pneumoniae MGH78578 and ATCC10031, to investigate reasons for the high drug resistance of K. pneumoniae MGH78578, and the results revealed that AcrAB from K. pneumoniae ATCC10031 conferred weaker drug resistance than AcrAB from K. pneumoniae MGH78578. DNA sequencing revealed that acrB from K. pneumoniae ATCC10031 carried the nonsense mutation, UGA, which was not found in acrB from K. pneumoniae MGH78578. However, acrB from K. pneumoniae ATCC10031 conferred slightly elevated resistant levels to several antimicrobials. The intact length of AcrB was detected in K. pneumoniae ATCC10031 by Western blot analysis, even though its quantity was small. Therefore, the stop codon UGA in acrB was thought to be overcome to some extent in this strain. We artificially introduced the nonsense mutation, UGA to the cat gene on pACYC184, and the plasmid also elevated the MIC of chloramphenicol in K. pneumoniae ATCC10031. These results suggest that a mechanism to overcome the nonsense mutation in acrB sustained resistance against a few β-lactams, dyes, and cholic acid in K. pneumoniae ATCC10031. © 2013 Elsevier B.V.

    The purpose of this study was to prove the hypothesis that C-reactive protein (CRP) and nerve growth factor (NGF) may be potential biomarkers for lower urinary tract disorders and may be able to distinguish between micturition dysfunctions of different origin in dogs with spinal cord diseases. NGF- and CRP- concentrations were measured in serum and urine samples using specific ELISA-Kits. Results in urine were standardized by urine-creatinine levels. CRP in serum was detectable in 32/76 and in urine samples in 40/76 patients. NGF could be measured in all serum and in 70/76 urine samples. Urinary CRP concentrations were significantly higher in dogs with micturition dysfunction (p = 0.0009) and in dogs with different neurological diseases (p = 0.0020) compared to the control group. However, comparing dogs with spinal cord disorders with and without associated micturition dysfunction no significant difference could be detected for NGF and CRP values in urine or serum samples. Additionally, levels did not decrease significantly, when measured at the time when the dogs regained the ability to urinate properly (urinary NGF p = 0.7962; urinary CRP p = 0.078). Urine samples with bacteria and/or leukocytes had no significant increase in urinary NGF (p = 0.1112) or CRP (p = 0.0534) concentrations, but higher CRP-levels in urine from dogs with cystitis were found compared to dogs without signs of cystitis. From these data we conclude that neither CRP nor NGF in urine or serum can be considered as reliable biomarkers for micturition disorders in dogs with spinal cord disorders in a clinical setting, but their production might be part of the pathogenesis of such disorders. Significantly higher levels of CRP could be found in the urine of dogs with micturition dysfunctions compared to control dogs. This phenomenon could potentially be explained by unspecific extrahepatic CRP production by smooth muscle cells in the dilated bladder.

This Interim Construction Quality Assurance (CQA) Report is for the 92-Acre Evapotranspiration Cover, Area 5 Waste Management Division (WMD) Retired Mixed Waste Pits, Nevada National Security Site, Nevada for the period of January 20, 2011 to May 12, 2011. Construction was approved by the Nevada Division of Environmental Protection (NDEP) under the Approval of Corrective Action Decision Document/Corrective Action Plan (CADD/CAP) for Corrective Action Unit (CAU) 111: Area 5 WMD Retired Mixed Waste Pits, Nevada National Security Site, Nevada, on January 6, 2011, pursuant to Subpart XII.8a of the Federal Facility Agreement and Consent Order. The project is located in Area 5 of the Radioactive Waste Management Complex (RWMC) at the Nevada National Security Site (NNSS), formerly known as the Nevada Test Site, located in southern Nevada, approximately 65 miles northwest of Las Vegas, Nevada, in Nye County. The project site, in Area 5, is located in a topographically closed basin approximately 14 additional miles north of Mercury Nevada, in the north-central part of Frenchman Flat. The Area 5 RWMS uses engineered shallow-land burial cells to dispose of packaged waste. The 92-Acre Area encompasses the southern portion of the Area 5 RWMS, which has been designated for the first final closure operations. This area contains 13 Greater Confinement Disposal (GCD) boreholes, 16 narrow trenches, and 9 broader pits. With the exception of two active pits (P03 and P06), all trenches and pits in the 92-Acre Area had operational covers approximately 2.4 meters thick, at a minimum, in most areas when this project began. The units within the 92-Acre Area are grouped into the following six informal categories based on physical location

    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.

    Erythrocyte sedimentation rate (ESR) might represent a less expensive alternative to C-reactive protein (CRP) as a marker of systemic inflammation in stable chronic obstructive pulmonary disease (COPD). We tried to verify this hypothesis in 223 consecutive outpatients aged 65 years or more with stable COPD enrolled in a multicenter observational study. Patients were grouped according to normal/increased ESR/CRP values and groups were compared with regard to clinical and laboratory characteristics. Correlations between CRP, ESR and selected variables of interest were assessed by Spearman's ζ-test and multivariate linear regression analysis. CRP was weakly and inversely correlated with the forced expiratory volume in the first second (FEV1%) (Spearman's ζ = -0.15; p < 0.027), while ESR was not (Spearman's ζ = -0.05; p = 0.411). The highest prevalence of anemia and hypoalbuminemia and the lowest FEV1% were recorded in high ESR-high CRP group. For anemia B = 14.180 ± 3.521 (± S.E.M.); p = 0.001 and hypoalbuminemia B = 10.241 ± 3.790; p = 0.007 qualified as significant independent correlates of ESR values, while only FEV1 remained significantly associated with CRP values (B = -0.570 ± 0.258; p = 0.028). In conclusion, CRP, but not ESR, shows a weak correlation with COPD severity, while anemia and hypoalbuminemia are main correlates of high ESR. Neither ESR, nor CRP qualify as reliable markers of COPD severity and seem to reflect the effects of different determinants. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    Association between elevated C-reactive protein (CRP) serum levels and subclinical atherosclerosis and cardiovascular (CV) events was described in rheumatoid arthritis (RA). CRP, HNF1A, LEPR, GCKR, NLRP3, IL1F10, PPP1R3B, ASCL1, HNF4A and SALL1 exert an influence on elevated CRP serum levels in non-rheumatic Caucasians. Consequently, we evaluated the potential role of these genes in the development of CV events and subclinical atherosclerosis in RA patients. Three tag CRP polymorphisms and HNF1A, LEPR, GCKR, NLRP3, IL1F10, PPP1R3B, ASCL1, HNF4A and SALL1 were genotyped in 2,313 Spanish patients by TaqMan. Subclinical atherosclerosis was determined in 1,298 of them by carotid ultrasonography (by assessment of carotid intima-media thickness-cIMT-and presence/absence of carotid plaques). CRP serum levels at diagnosis and at the time of carotid ultrasonography were measured in 1,662 and 1,193 patients, respectively, by immunoturbidimetry. Interestingly, a relationship between CRP and CRP serum levels at diagnosis and at the time of the carotid ultrasonography was disclosed. However, no statistically significant differences were found when CRP, HNF1A, LEPR, GCKR, NLRP3, IL1F10, PPP1R3B, ASCL1, HNF4A and SALL1 were evaluated according to the presence/absence of CV events, carotid plaques and cIMT after adjustment. Our results do not confirm an association between these genes and CV disease in RA. PMID:27534721

    2010-02-01

    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.

    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.

  4. Improving ethanol tolerance of Escherichia coli by rewiring its global regulator cAMP receptor protein (CRP.

    Full Text Available A major challenge in bioethanol fermentation is the low tolerance of the microbial host towards the end product bioethanol. Here we report to improve the ethanol tolerance of E. coli from the transcriptional level by engineering its global transcription factor cAMP receptor protein (CRP, which is known to regulate over 400 genes in E. coli. Three ethanol tolerant CRP mutants (E1- E3 were identified from error-prone PCR libraries. The best ethanol-tolerant strain E2 (M59T had the growth rate of 0.08 h(-1 in 62 g/L ethanol, higher than that of the control at 0.06 h(-1. The M59T mutation was then integrated into the genome to create variant iE2. When exposed to 150 g/l ethanol, the survival of iE2 after 15 min was about 12%, while that of BW25113 was <0.01%. Quantitative real-time reverse transcription PCR analysis (RT-PCR on 444 CRP-regulated genes using OpenArray® technology revealed that 203 genes were differentially expressed in iE2 in the absence of ethanol, whereas 92 displayed differential expression when facing ethanol stress. These genes belong to various functional groups, including central intermediary metabolism (aceE, acnA, sdhD, sucA, iron ion transport (entH, entD, fecA, fecB, and general stress response (osmY, rpoS. Six up-regulated and twelve down-regulated common genes were found in both iE2 and E2 under ethanol stress, whereas over one hundred common genes showed differential expression in the absence of ethanol. Based on the RT-PCR results, entA, marA or bhsA was knocked out in iE2 and the resulting strains became more sensitive towards ethanol.

    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. PMID:26106150

    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

    C-reactive protein (CRP) is often elevated in patients living with severe obesity (BMI≥35kg/m(2)). However, there is limited information on how CRP, and other inflammation responsive biomarkers, change in response to weight loss following laparoscopic sleeve gastrectomy (LSG). We studied how CRP, ferritin and albumin change following LSG surgery in relation to obesity, metabolic syndrome (MetS) ATPIII risk components and diabetes mellitus (DM). Laboratory parameters (including CRP) were examined in 197 patients prior to LSG, and at 6, 12, 18 and 24months. Changes in laboratory parameters, and laboratory investigations, were also examined in a 125 patient subgroup at both pre-LSG and at the 12month follow-up visit. All patients had BMI≥35kg/m(2). CRP levels positively correlated with BMI (r=0.171, p=0.016) and alkaline phosphatase (ALP; r=0.309; P<0.001), but negatively correlated with alanine aminotransferase (ALT; r=-0.260; P<0.001) and albumin (r=-0.358; P<0.001). LSG significantly reduced CRP and ferritin, which were maintained for at least 24months. At 12months post-LSG there was a significant decrease in weight (kgs) (p<0.001), CRP (p<0.001), ferritin (p=0.004), and various MetS risk components (p<0.001) but not albumin (p=0.057). Changes in CRP also correlated with changes in weight (r=0.233, p=0.018) and ALP (r=0.208, p=0.034) but not albumin (r=-0.186, p=0.058) or ferritin (r=0.160, p=0.113) after LSG. The negative correlation between CRP and albumin levels in obesity may indicate a low grade inflammatory process affecting both. LSG related weight loss decreased CRP and ferritin, likely explained by improvement in inflammatory status. Copyright © 2017 The Canadian Society of Clinical Chemists. Published by Elsevier Inc.

    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...

    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.

    Full Text Available Objective: To explore the effect of hs-CRP level and nutritional status on the pulmonary function in patients with maintenance hemodialysis (MHD. Methods: A total of 30 patients with chronic renal failure (CRF who were admitted in our hospital from August, 2014 to August, 2015 for hemodialysis were included in the study. A volume of 4mL morning fasting elbow venous blood before and after hemodialysis was extracted, and was then centrifuged for serum. The levels of Hb, Alb, and PA were detected. VC, FVC, FEV1, FEV1/ FVC, PEF, and MMEF were determined. Results: The levels of Hb, Alb, and PA after hemodialysis were significantly higher than those before hemodialysis (P<0.05. VC, FVC, FEV1, FEV1/FVC, PEF, and MMEF after hemodialysis were significantly improved when compared with before treatment (P<0.05. The comparison of VC, FVC, FEV1, FEV1/FVC, PEF, and MMEF among patients with different levels of hs-CRP was statistically significant (P<0.05. Conclusions: The reduction of pulmonary function in different degrees exists in MHD patients. MHD is kind of effective method to improve the pulmonary function in patients with CRF. The effective improvement of nutritional status and the reduction of in vivo inflammatory reaction in patients with CRF in the clinic can relieve the deterioration of pulmonary function to a certain degree so that to improve the ventilation function and enhance the living quality.

    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.

    Major porins are among the most abundant proteins embedded in the outer membrane (OM) of Gram-negative bacteria, playing crucial roles in maintenance of membrane structural integrity and OM permeability. Although many OM proteins (especially c-type cytochromes) in Shewanella oneidensis, a research model for respiratory versatility, have been extensively studied, physiological significance of major porins remains largely unexplored. In this study, we show that OmpS38 and OmpA are two major porins, neither of which is responsive to changes in osmolarity or contributes to the intrinsic resistance to β-lactam antibiotics. However, OmpS38 but not OmpA is largely involved in respiration of non-oxygen electron acceptors. We then provide evidence that expression of ompS38 is transcribed from two promoters, the major of which is favored under anaerobic conditions while the other appears constitutive. The major promoter is under the direct control of Crp, the master regulator dictating respiration. As a result, the increase in the level of OmpS38 correlates with an elevated activity in Crp under anaerobic conditions. In addition, we show that the activity of the major promoter is also affected by Fur, presumably indirectly, the transcription factor for iron-dependent gene expression.

    Human mobility, presence and passive transportation of Aedes aegypti mosquito, and environmental characteristics are a group of factors which contribute to the success of dengue spread and establishment. To understand this process, we assess data from dengue national and municipal basins regarding population and demographics, transportation network, human mobility, and Ae. aegypti monitoring for the Brazilian state of Acre since the first recorded dengue case in the year 2000 to the year 2015. During this period, several changes in Acre's transport infrastructure and urbanization have been started. To reconstruct the process of dengue introduction in Acre, we propose an analytic framework based on concepts used in malaria literature, namely vulnerability and receptivity, to inform risk assessments in dengue-free regions as well as network theory concepts for disease invasion and propagation. We calculate the probability of dengue importation to Acre from other Brazilian states, the evolution of dengue spread between Acrean municipalities and dengue establishment in the state. Our findings suggest that the landscape changes associated with human mobility have created favorable conditions for the establishment of dengue virus transmission in Acre. The revitalization of its major roads, as well as the increased accessibility by air to and within the state, have increased dengue vulnerability. Unplanned urbanization and population growth, as observed in Acre during the period of study, contribute to ideal conditions for Ae. aegypti mosquito establishment, increase the difficulty in mosquito control and consequently its local receptivity.

    Inflammation plays a pivotal role throughout the formation and progression of atherosclerosis. As the most representative inflammatory marker, C-reactive protein (CRP) directly participates in the initiation and development of atherosclerosis. The elevated homocysteine (Hcy) level in plasma is an independent risk factor for atherosclerosis. We previously reported that Hcy produces a pro-inflammatory effect by stimulating CRP expression in vascular smooth muscle cells (VSMCs). The present study observed the effect of simvastatin on Hcy-induced CRP expression in VSMCs and the molecular mechanisms. The in vitro experiments revealed that pretreatment of VSMCs with simvastatin decreased Hcy-induced mRNA and protein expression of CRP in a concentration-dependent fashion. The in vivo results showed that simvastatin not only inhibited CRP expression in the vessel walls in mRNA and protein levels, but also reduced the circulating CRP level in hyperhomocysteinemic rats. Further experiments displayed that simvastatin reduced Hcy-induced reactive oxygen species (ROS) generation, ameliorated Hcy-activated phosphorylations of ERK1/2 and p38, and antagonized Hcy-downregulated peroxisome proliferator-activated receptor gamma expression in VSMCs. These data demonstrate that simvastatin is able to inhibit Hcy-induced CRP generation in VSMCs so to relieve the vascular inflammatory response via interfering with the ROS-MAPK signal pathway. The present results provide new evidence for understanding of the potential anti-inflammatory and anti-atherosclerotic effects of simvastatin. As the high level of Hcy in plasma is related to atherosclerosis formation and mediates cardiovascular risk, our findings emphasize the importance and necessity of therapy with statins for hyperhomocysteinemia in atherosclerosis.

    Endometrial cancer (EC) rates are rising in Japan. Lymph node (LN) metastasis is an important prognostic factor in EC, and its risk is increased with higher tumor grade, deep myometrial invasion, larger tumor size, and lymphovascular space invasion (LVSI). Current methodologies to assess these factors are unreliable. We previously showed the association between C-reactive protein (CRP) 1846C>T (rs1205) polymorphism and LN metastasis in esophageal, non-small cell lung, and breast cancers. The CRP gene is located on chromosome 1q21-q23, and the polymorphism in the noncoding region (1846C>T) of this gene decreases serum CRP levels. We investigated the relationship between CRP 1846C>T genetic polymorphism and LN metastasis or LVSI in 130 EC patients using polymerase chain reaction-restriction fragment length polymorphism. The CRP 1846C/T genotype was C/C in 11 patients, C/T in 58 patients and T/T in 61 patients. The patients were divided into two groups based on their CRP 1846 genotypes: "C/C" and "C/T + T/T". Nine (7%) and 18 (13%) patients, all with the polymorphism, had LN metastasis and moderate or prominent lymphatic invasion, respectively. LN metastasis and/or severe lymphatic invasion were observed in the C/T + T/T group, while patients with the C/C genotype had no LN metastases or severe lymphatic invasion. Univariate and multivariate logistic regression models revealed that the C/T + T/T patients had a significant likelihood of developing LN metastasis and/or severe lymphatic invasion. Our results suggest that CRP genetic polymorphism is a novel risk predictor of LN metastasis and/or lymphatic invasion in EC.

    Full Text Available Objective  To investigate the value of ultrasound combined with tumor marker CA19-9 and high sensitivity C reactive protein (hs-CRP on the accuracy of early diagnosis of gallbladder cancer. Methods  Ninety-five patients with pathologically confirmed primary gallbladder cancer who received cholecystectomy from Jan. 2008 to Jan. 2013 in our hospital were included in the study. The study also included 51 patients with benign cystic lesions and 51 healthy adults. In all patients, results of pathological examination, B-ultrasound, serum CA19-9 and hs-CRP detection were obtained. In all the healthy adults gallbladder diseases were ruled out, but all of them received serum CA19-9 and hs-CRP determination. Results  Of 95 patients with primary gallbladder cancer, B-ultrasound showed nodules in the gallbladder lumen in 31, tumor mass in 40, and thickened wall in 24. Histological examination showed adenocarcinoma in 87 cases, adenosquamous carcinoma in 6, and squamous carcinoma in 2. There was a statistical difference in hs-CRP and CA19-9 levels between the groups (P<0.05, and the highest level appeared in gallbladder cancer group. There was a high sensitivity but low specificity of CA19-9 or hs-CRP in the diagnosis of primary gallbladder cancer. The sensitivity and specificity were 74.7% and 75.0% when primary gallbladder cancer was diagnosed with B-ultrasound. The positive values of CA19-9 and hs-CRP were ≥100U/ml and ≥6mg/L respectively, when they were combined with B-ultrasound as a single serology factor. When both B-ultrasound and serum levels of CA19-9 and hs-CRP were positive, the diagnostic sensitivity and specificity were 71.6% and 84.4% respectively. When B-ultrasound or serum CA19-9 and hs-CRP were positive, the diagnostic sensitivity and specificity were 98.9% and 66.7% respectively. Conclusions  Combination of B-ultrasound and determination of serum of CA19-9 and hs-CRP can improve the accuracy of the diagnosis of gallbladder

    The aim of this study was to determine the prevalence of and factors associated with overweight among university students from the city of Rio Branco, Acre, Brazil. A cross-sectional study was conducted on 1,104 students (mean age: 24 years from Rio Branco, Acre. Overweight was used as the dependent variable. The following independent variables were studied: socioeconomic variables (gender, age, teaching institution, period of study, marital status, income, household members, living with other people, parent’s education level, and working or not; self-reported health and morbidity variables (health perception, hypertension, diabetes, and altered cholesterol; lifestyle variables (physical activity, watching television, computer use, smoking, and alcohol consumption. The nutritional status was classified based on body mass index. Univariate analysis was performed using Pearson’s chi-squared test or Fisher’s exact test. Variables with a p value < 20% on univariate analysis were included in the multiple Poisson regression model. The prevalence of overweight was 35.6%. In the multiple regression model for male students adjusted for age, overweight was associated with marital status, household income, hypertension, and watching television every day. In the model for female students, the variables that remained associated were self-perceived health status, hypertension, and alcohol consumption in the last month. Overweight is determined by a combination of different factors which differed in the present study between men and women.

    Trichoderma is an anamorphic filamentous fungal genus with immense potential for production of small valuable secondary metabolites with indispensable biological activities. Microbial dynamics of a psychrotrophic strain Trichoderma velutinum ACR-P1, isolated from unexplored niches of the Shiwalik region, bestowed with rich biodiversity of microflora, was investigated for production of nonribosomal peptides (NRPs) by metabolite profiling by intact-cell mass spectrometry (ICMS) employing matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometer. Being the first report on NRPs production by T. velutinum, studies on optimization of growth conditions by Response Surface Methodology (RSM) for production of NRPs by ACR-P1 was carried out strategically. Multifold enhancement in the yield of NRPs belonging to subfamily SF4 with medium chain of amino acid residues having m/z 1437.9, 1453.9, and 1452.0 at pH 5.9 at 20 °C and of subfamily SF1 with long-chain amino acid residues having m/z 1770.2, 1784.2, 1800.1, 1802.1, and 1815.1 was achieved at pH 7.0 at 25 °C. Complexities of natural mixtures were thus considerably reduced under respective optimized culture conditions accelerating the production of novel microbial natural products by saving time and resources.

    Full Text Available The variety of soils in the State of Acre is wide and their chemical profiles are still not fully understood. The nature of the material of origin of these soils is indicated by the high aluminium (Al content, commonly associated with high calcium (Ca and magnesium (Mg contents. The study objective was to use different methods to quantify Al in soils from toposequences formed from material of a sedimentary nature originating from the Solimões Formation, in Acre, Brazil. Trenches were opened at three distinct points in the landscape: shoulder, backslope and footslope positions. Soil samples were collected for physical, chemical, mineralogical analyses. The Al content was quantified using different methods. High Al contents were found in most of these horizons, associated with high Ca and Mg levels, representing the predominant cations in the sum of exchangeable bases. The mineralogy indicates that the soils are still in a low weathering phase, with the presence of significant quantities of 2:1 minerals. Similar Al contents were determined by the methods of NaOH titration, xylenol orange spectrometry and inductively coupled plasma optical emission spectrometry. However, no consistent data were obtained by the pyrocatechol violet method. Extraction with KCl overestimated the exchangeable Al content due to its ability to extract the non-exchangeable Al present in the smectite interlayers. It was observed that high Al contents are related to the instability of the hydroxyl-Al smectite interlayers.

    Breast cancer is the most common non-skin cancer and the second leading cause of cancer death for women in the United States. Before the introduction of widespread mammographic screening in the mid-1980s, the death rate from breast cancer in the US had remained unchanged for more than 4 decades. Since 1990, the death rate has declined by at least 38%. Much of this change is attributed to early detection with mammography. ACR breast cancer screening experts have reviewed data from RCTs, observational studies, US screening data, and other peer-reviewed literature to update our recommendations. Mammography screening has consistently been shown to significantly reduce breast cancer mortality over a variety of study designs. The ACR recommends annual mammography screening starting at age 40 for women of average risk of developing breast cancer. Our recommendation is based on maximizing proven benefits, which include a substantial reduction in breast cancer mortality afforded by regular screening and improved treatment options for those diagnosed with breast cancer. The risks associated with mammography screening are also considered to assist women in making an informed choice. Copyright © 2017 American College of Radiology. Published by Elsevier Inc.

    Fibromyalgia (FM) is difficult to diagnose and manage chronic pain condition whose symptoms have no clear pathophysiological cause, although it is thought that patient hypersensitivity to a range of stimuli may give rise to mechanical hyperalgesia as a result of altered central nociceptive processing. The 1990 American College of Rheumatology (ACR) classification criteria, which have been widely used in clinical practice, require the existence of chronic widespread pain (CWP) for >3months, and the presence of at least 11 out of 18 specified tender points upon digital palpation, although this latter criterion has long been criticised. The newer 2010 ACR diagnostic criteria state that FM can be defined as CWP associated with somatic symptoms, and recommend the use of a widespread pain index and a scale to rate symptom severity. A modified version of the 2010 criteria removed the physician assessment of the extent of somatic symptoms and replaced it by a summary score of three self-reported symptoms, thus making it easier to use while maintaining its sensitivity. This review discusses the advantages and limitations of all of these criteria. Copyright © 2017 Elsevier B.V. All rights reserved.

    The aim of the study was to evaluate whether two dietary approaches recommended for diabetes mellitus and cardiovascular prevention-high-MUFA or complex carbohydrates/fiber-differently influence inflammation. A 4-week crossover study in 12 individuals with type 2 diabetes was performed. Fasting and postprandial hs-CRP plasma levels were not significantly different after a high-carbohydrate/high-fiber/low-glycemic index (CHO/fiber) and a high-MUFA diet. Compared with fasting, hs-CRP levels decreased significantly after the MUFA but not after the CHO/fiber meal. Triglyceride-rich lipoproteins were significantly lower after the CHO/fiber than the MUFA diet. At fasting and postprandially, hs-CRP correlated with triglyceride in whole plasma, chylomicrons, small and large VLDL after the CHO/fiber but not after the MUFA diet. In conclusion, a MUFA-rich diet and a carbohydrate/fiber-rich diet induced similar effects on plasma hs-CRP concentrations. However, these dietary approaches seem to influence hs-CRP levels through different mechanisms. i.e., direct acute postprandial effects by MUFA and triglyceride-rich lipoproteins mediated effects by CHO/fiber.

    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 Background: The C-reactive protein (CRP and the tumor necrosis factor-alpha (TNF-α are considered markers of inflammation and have been shown to predict the risk of incident cardiovascular events. However, few studies have undertaken a comprehensive examination of SNPs (single nucleotide polymorphisms of the CRP and TNF-α genes; due to this, we will present a protocol study to evaluate the role of the CRP and TNF-α genes in Mexican individuals. Methods/design: we will perform a case-control study to explore the CRP and TNF-α genotype distribution as well as the serum influence of rs1800947, rs1130864, rs2794521 and rs1205 (polymorphisms of the CRP gene and rs361525, rs1800629, rs1799724, rs1800630, rs1799964 (of the TNF-α gene in Mexican individuals who present coronary artery disease. Ethics and dissemination: a written informed consent will be obtained from all the participating subjects. An article detailing the results of the study will be submitted for publication in an international peer-reviewed journal, in accordance with STROBE criteria.

    Coronary Artery Disease (CAD) is clearly a multifactorial disease that develops from childhood and ultimately leads to death. Several reports revealed having a First Degree Relatives (FDRS) with premature CAD is a significant autonomous risk factor for CAD development. C - reactive protein (CRP) is a member of the pentraxin family and is the most widely studied proinflammatory biomarker. IL-18 is a pleiotrophic and proinflammatory cytokine which is produced mainly by macrophages and plays an important role in the inflammatory cascade. Hs-CRP levels were estimated by ELISA and Genotyping of IL-18 gene variant located on promoter -137 (G/C) by Allele specific PCR in blood samples of 300 CAD patients and 300 controls and 100 FDRS. Promoter Binding sites and Protein interacting partners were identified by Alibaba 2.1 and Genemania online tools respectively. Hs-CRP levels were significantly high in CAD patients followed by FDRS when compared to controls. In IL-18 -137 (G/C) polymorphism homozygous GG is significantly associated with occurrence of CAD and Hs-CRP levels were significantly higher in GG genotype subjects when compared to GC and CC. IL-18 was found to be interacting with 100 protein interactants. Our results indicate that Hs-CRP levels and IL-18-137(G/C) polymorphism may help to identify risk of future events of CAD in asymptomatic healthy FDRS.

    Full Text Available The natural immune response to infectious agents is partially mediated by a group of proteins named acute phase proteins; one of the major and most important proteins from the acute phase is the C-Reactive Protein (CRP. The aim of the present study was to investigate the correlation between alterations on white blood cell counts (WBC and the presence of circulating CRP. Blood samples from 70 dogs were submitted to hematological examination and detection of CRP; in addition, blood samples from 12 dogs experimentally inoculated with an inactivated sample of Micrococcus luteus (ATCC 7468 were also analyzed. According to the hematological parameters and CRP values, the samples were classified in 5 different groups: group A dogs without CRP and normal WBC; group B dogs with elevated levels of CRP but normal WBC; group C dogs with elevated CRP values and altered WBC (neutrophilia and leukocytosis; group D dogs with both CRP and increased neutrophils values; and group E dogs with elevated CRP values but with leukopenia. Dogs experimentally inoculated with M. luteus had a significant and promt increase in CRP values between 24 and 48 hr p.i., which declined up to the 10th day when the experiment was completed. In these dogs, a discrete neutrophilia and leukocytosis was observed coincidently with the CRP elevation. Thus, it can be suggested that the detection of CRP in the blood of dogs should be used as an indication of an infection or inflammation and, because of the low amount of blood needed, low cost and easiness to perform the test, monitoring CRP levels might be useful to evaluate the recovery from an infection disease.

    Full Text Available It is instrumental for the Mycobacterium tuberculosis (Mtb to persist within its host in dormancy. Mtb represses most of its metabolic machinery during latency, but upregulates the expression of latency-associated protein alpha-crystallin protein (Acr1. Therefore, it is imperative to understand how throughout dormancy, Mtb employs Acr1 to regulate the host immunity. This study reveals that Acr1 exhibits divergent effect on the pre- and post-maturation stages of dendritic cells (DCs. In the current study, we demonstrate that early encounter of bone marrow cells with Acr1 while differentiating into DCs (AcrDCpre, leads to impairment in their maturation. In contrast, when exposed to Acr1 after maturation (AcrDCpost, DCs show augmentation in their activity, secretion of TNF-α, IL-12, IL-6, and activation of T cells. Additionally, AcrDCpost promoted the polarization of naïve CD4 T cells to Th1 cells and Th17 cells and restricted the intracellular growth of Mtb. Furthermore, these DCs upregulated the expression of CCR7 and exhibited enhanced migratory capabilities. The discrete impact of Acr1 on DCs is mediated through a mechanism involving STAT-1, SOCS-3, ERK, TLR-4, and NF-κB signaling pathways. This study reveals the unprecedented role of Acr1 in distinctly modulating the function of DCs at different stages of maturation.

    Psychological stress at work is considered a cardiac risk factor, yet whether it acts directly through neuroimmune processes, or indirectly by increasing behavioral risk factors, is uncertain. Cross-sectional associations between job strain and serum biomarkers of inflammation and endothelial dysfunction were investigated. Secondary analyses explored the role of psychosocial/cardiometabolic risk factors as mediators of job stress associated inflammation in healthy workers. Information on risk factors was obtained in standardized personal interviews of a subcohort of working participants in the MONICA/KORA population (n = 951). Work stress was measured by the Karasek job strain index. Biomarkers were measured from non-fasting venous blood. Multivariate regression analyses were used to examine the association of job strain with inflammatory biomarkers. Mediation analysis (Sobel test) was used to determine the effect of psychosocial risk factors on the association between job strain and C-reactive protein (CRP). High job strain was reported by half (n = 482, 50.7%) of the study participants. While workers with high job strain were more likely to have adverse workplace conditions (competition with coworkers, job dissatisfaction and insecurity), sleeping problems, depressive symptoms, a Type A personality, and be physically inactive, no differences in cardiometabolic risk factors were detected. A strong and robust association between job strain and CRP was observed in age and sex adjusted models, as well as models adjusted for classic coronary heart disease risk factors (β = 0.39, p = 0.006 and β = 0.27, p = 0.03, respectively). Adjustment for physical activity abrogated this effect (β = 0.23, p = 0.07), and a mediating effect of physical activity on stress-associated inflammation was demonstrated (p = 0.04). The analyses provide evidence for both a direct and an indirect effect of job strain on inflammation. Copyright © 2012 Elsevier Inc. All rights reserved.

    We have isolated and sequenced a Neurospora crassa gene encoding a single copy of ubiquitin (UBI) fused to the S27a ribosomal (r) protein. We have opted to name this gene the ubiquitin/cytoplasmic r-protein gene 6 (ubi::crp-6). The ubi::crp-6 gene generates a 700-nucleotide (nt) transcript. It shares a 700-bp regulatory region with the cytoplasmic r-protein gene 5 (crp-5), a gene encoding the N. crassa S26 r-protein. The two genes are transcribed divergently from the common regulatory region and their mRNA levels are regulated in parallel during growth on a variety of carbon sources.

    Endometrial remodeling is important for successful embryo development and implantation in pigs. Therefore, this study investigated change of proteins regulating endometrial remodeling on follicular and luteal phase in porcine endometrial tissues. The endometrial tissue samples were collected from porcine uterus during follicular and luteal phase, vascular endothelial growth factor (VEGF), myoglobin and cysteine-rich protein 2 (CRP2) proteins were expressed by immnofluorescence, immunoblotting, and determined by 2-DE and MALDI-TOF/MS. We found that VEGF, myoglobin and CRP2 were strongly localized in endometrial tissues during luteal phase, but not follicular phase. The protein levels of VEGF, myoglobin and CRP2 in endometrial tissues were higher than luteal phase (P < 0.05). These results may provide understanding of intrauterine environment during estrous cycle in pigs, and will be used in animal reproduction for developing specific biomarkers in the future. © 2017 Japanese Society of Animal Science.

    Full Text Available OBJECTIVES: It has been shown in early arthritis cohorts that the 2010 ACR/EULAR criteria for rheumatoid arthritis (RA enable an earlier diagnosis, perhaps at the cost of a somewhat more heterogeneous patient population. We describe the features of synovial inflammation in RA patients classified according to these new criteria. METHODS: At baseline, synovial tissue biopsy samples were obtained from disease-modifying antirheumatic drug (DMARD-naïve early RA patients (clinical signs and symptoms <1 year. Synovial tissue was analyzed for cell infiltration, vascularity, and expression of adhesion molecules. Stained sections were evaluated by digital image analysis. Patients were classified according to the two different sets of classification criteria, autoantibody status, and outcome. FINDINGS: Synovial tissue of 69 RA patients according to 2010 ACR/EULAR criteria was analyzed: 56 patients who fulfilled the criteria for RA at baseline and 13 who were initially diagnosed as undifferentiated arthritis but fulfilled criteria for RA upon follow up. The synovium at baseline was infiltrated by plasma cells, macrophages, and T cells as well as other cells, and findings were comparable to those when patients were selected based on the 1987 ACR criteria for RA. There was no clear cut difference in the characteristics of the synovium between RA patients initially diagnosed as undifferentiated arthritis and those who already fulfilled classification criteria at baseline. CONCLUSION: The features of synovial inflammation are similar when the 2010 ACR/EULAR classification criteria are used compared to the 1987 ACR criteria.

    High-Dose-Rate (HDR) brachytherapy is a safe and efficacious treatment option for patients with a variety of different malignancies. Careful adherence to established standards has been shown to improve the likelihood of procedural success and reduce the incidence of treatment-related morbidity. A collaborative effort of the American College of Radiology (ACR) and American Society for Therapeutic Radiation Oncology (ASTRO) has produced a practice guideline for HDR brachytherapy. The guideline defines the qualifications and responsibilities of all the involved personnel, including the radiation oncologist, physicist and dosimetrists. Review of the leading indications for HDR brachytherapy in the management of gynecologic, thoracic, gastrointestinal, breast, urologic, head and neck, and soft tissue tumors is presented. Logistics with respect to the brachytherapy implant procedures and attention to radiation safety procedures and documentation are presented. Adherence to these practice guidelines can be part of ensuring quality and safety in a successful HDR brachytherapy program. Copyright © 2011. Published by Elsevier Inc.

    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

    It is widely acknowledged that cardiovascular heart disease (CHD) has a genetic influence. Several studies have investigated the role of inflammatory markers like C-reactive protein (CRP) and tumor necrosis factor α (TNF-α) in the causation of cardiovascular diseases. Although there have been several positive studies associating CRP and TNF-α genes with CHD, the evidence is not entirely consistent. Therefore, we performed a meta-analysis to gain a better understanding into this issue. The meta-analysis was conducted with 22 articles of genetic association studies of CRP (G1059C rs1800947, C1444T rs1130864, C717T rs2794521 and G3872A rs1205) and TNF-α (C857T rs1799724, C863A rs1800630 and T1031C rs1799964) genes. To analyze the association of these variants with CHD we used the following models: allelic, additive, dominant and recessive. In addition, we performed a sub-group analysis by Caucasian population using the same four models. CRP and TNF-α gene polymorphisms showed a positive significant association with CHD. This study provides evidence that rs2794521 of the CRP gene and rs1799724, rs1800630 and rs1799964 of the TNF-α gene polymorphisms may be risk factors to manifest CHD. The analysis of rs1800947 and rs1205 of the CRP gene yielded a protective effect in the pathogenesis of this disease. Only the analysis of the rs1130864 polymorphism showed a lack of association with CHD. To have conclusive outcomes it is necessary to integrate more studies to confirm our findings.

    In the genome of Shewanella oneidensis, genes encoding the global regulators ArcA, Crp, and EtrA have been identified. All these proteins deviate from their counterparts in E. coli significantly in terms of functionality and regulon. It is worth investigating the involvement and relationship of these global regulators in aerobic and anaerobic respiration in S. oneidensis. In this study, the impact of the transcriptional factors ArcA, Crp, and EtrA on aerobic and anaerobic respiration in S. oneidensis were assessed. While all these proteins appeared to be functional in vivo, the importance of individual proteins in these two major biological processes differed. The ArcA transcriptional factor was critical in aerobic respiration while the Crp protein was indispensible in anaerobic respiration. Using a newly developed reporter system, it was found that expression of arcA and etrA was not influenced by growth conditions but transcription of crp was induced by removal of oxygen. An analysis of the impact of each protein on transcription of the others revealed that Crp expression was independent of the other factors whereas ArcA repressed both etrA and its own transcription while EtrA also repressed arcA transcription. Transcriptional levels of arcA in the wild type, crp, and etrA strains under either aerobic or anaerobic conditions were further validated by quantitative immunoblotting with a polyclonal antibody against ArcA. This extensive survey demonstrated that all these three global regulators are functional in S. oneidensis. In addition, the reporter system constructed in this study will facilitate in vivo transcriptional analysis of targeted promoters.

  13. Stress Introduction Rate Alters the Benefit of AcrAB-TolC Efflux Pumps.

    Stress tolerance studies are typically conducted in an all-or-none fashion. However, in realistic settings-such as in clinical or metabolic engineering applications-cells may encounter stresses at different rates. Therefore, how cells tolerate stress may depend on its rate of appearance. To address this, we studied how the rate of stress introduction affects bacterial stress tolerance by focusing on a key stress response mechanism. Efflux pumps, such as AcrAB-TolC of Escherichia coli , are membrane transporters well known for the ability to export a wide variety of substrates, including antibiotics, signaling molecules, and biofuels. Although efflux pumps improve stress tolerance, pump overexpression can result in a substantial fitness cost to the cells. We hypothesized that the ideal pump expression level would involve a rate-dependent trade-off between the benefit of pumps and the cost of their expression. To test this, we evaluated the benefit of the AcrAB-TolC pump under different rates of stress introduction, including a step, a fast ramp, and a gradual ramp. Using two chemically diverse stresses, the antibiotic chloramphenicol and the jet biofuel precursor pinene, we assessed the benefit provided by the pumps. A mathematical model describing these effects predicted the benefit as a function of the rate of stress introduction. Our findings demonstrate that as the rate of introduction is lowered, stress response mechanisms provide a disproportionate benefit to pump-containing strains, allowing cells to survive beyond the original inhibitory concentrations. IMPORTANCE Efflux pumps are ubiquitous in nature and provide stress tolerance in the cells of species ranging from bacteria to mammals. Understanding how pumps provide tolerance has far-reaching implications for diverse fields, from medicine to biotechnology. Here, we investigated how the rate of stressor appearance impacts tolerance. We focused on two distinct substrates of AcrAB-TolC efflux pumps, the

    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

    Full Text Available In this paper we present data on soil microbial biomass and heterotrophic respiration in pastures, mature and secondary forests, in order to elucidate their contribution to total CO2 flux from soil to atmosphere. The research was conducted in Southwestern Amazonia, Acre State, Brazil. Microbial biomass was estimated using a variation of the traditional fumigation-extraction method and heterotrophic respiration was measured using respirometry flasks attached to an infrared gas analyzer. Soil microbial biomass and heterotrophic respiration did not differ statistically among pastures, mature and secondary forests. These laboratory results indicate that higher CO2 fluxes from pasture soils measured in situ are probably due to higher root respiration by pasture grasses.

    Full Text Available This work was conducted in five oxbow lakes located between Cruzeiro do Sul and Rodrigues Alves counties (Acre State, Brazil, to provide additional information about the composition of zooplankton assemblages in the Upper Juruá River. Samples were collected from May 2009 to May 2010, and fixed with 4% formalina. The numeric density (ind.m -3 was obtained from subsequent sub-samples (1 mL. The study recorded 19 zooplankton families. Rotifers showed higher species richness (81 species, followed by cladocerans (3 species and various forms of copepods and other organisms. Higher zooplankton means of numeric density was found in Novo Lake, with rotifers (1879 ind.m -3, cladocerans (207 ind.m -3, copepods (870 ind.m -3 . Diversity and numeric density were similar to other Neotropical aquatic ecosystems.

    The AcrB protein of Escherichia coli, together with TolC and AcrA, forms a contiguous envelope conduit for the capture and extrusion of diverse antibiotics and cellular metabolites. In this study, we sought to expand our knowledge of AcrB by conducting genetic and functional analyses. We began with an AcrB mutant bearing an F610A substitution in the drug binding pocket and obtained second-site substitutions that overcame the antibiotic hypersusceptibility phenotype conferred by the F610A mutation. Five of the seven unique single amino acid substitutions--Y49S, V127A, V127G, D153E, and G288C--mapped in the periplasmic porter domain of AcrB, with the D153E and G288C mutations mapping near and at the distal drug binding pocket, respectively. The other two substitutions--F453C and L486W--were mapped to transmembrane (TM) helices 5 and 6, respectively. The nitrocefin efflux kinetics data suggested that all periplasmic suppressors significantly restored nitrocefin binding affinity impaired by the F610A mutation. Surprisingly, despite increasing MICs of tested antibiotics and the efflux of N-phenyl-1-naphthylamine, the TM suppressors did not improve the nitrocefin efflux kinetics. These data suggest that the periplasmic substitutions act by influencing drug binding affinities for the distal binding pocket, whereas the TM substitutions may indirectly affect the conformational dynamics of the drug binding domain. The AcrB protein and its homologues confer multidrug resistance in many important human bacterial pathogens. A greater understanding of how these efflux pump proteins function will lead to the development of effective inhibitors against them. The research presented in this paper investigates drug binding pocket mutants of AcrB through the isolation and characterization of intragenic suppressor mutations that overcome the drug susceptibility phenotype of mutations affecting the drug binding pocket. The data reveal a remarkable structure-function plasticity of the

    II 1a. The steady state core calculations were simulated with the INL coupled-code system known as the Parallel and Highly Innovative Simulation for INL Code System (PHISICS) and the system thermal-hydraulics code known as the Reactor Excursion and Leak Analysis Program (RELAP) 5 3D using the nuclear data libraries previously generated with NEWT. It was observed that significant differences in terms of multiplication factor and neutron flux exist between the various permutations of the Phase I super-cell lattice calculations. The use of these cross section libraries only leads to minor changes in the Phase II core simulation results for fresh fuel but shows significantly larger discrepancies for spent fuel cores. Furthermore, large incongruities were found between the SCALE NEWT and KENO VI results for the super cells, and while some trends could be identified, a final conclusion on this issue could not yet be reached. This report will be revised in mid 2016 with more detailed analyses of the super-cell problems and their effects on the core models, using the latest version of SCALE (6.2). The super-cell models seem to show substantial improvements in terms of neutron flux as compared to single-block models, particularly at thermal energies.

    Full Text Available Background: There are few reports regarding the effect of long-term soy protein consumption among type 2 diabetic patients with nephropathy. This study was conducted to elucidate the effects of soy consumption for a long period of time on cardiovascular risks, C-reactive protein (CRP and kidney function indexes among type 2 diabetic patients with nephropathy. Materials & Methods: This long-term randomized clinical trial was conducted among 41 type 2 diabetic patients with nephropathy (18 men and 23 women. Twenty patients in the soy protein group consumed a diet containing 0.8 g protein/kg body weight (35% animal proteins, 35% textured soy protein, and 30% vegetable proteins and 21 patients in the control group consumed a similar diet containing 70% animal proteins and 30% vegetable proteins for 4 years. Results: Soy protein consumption significantly improved cardiovascular risks such as fasting plasma glucose (mean change in the soy protein versus control groups: −18 ± 3 vs. 11 ± 2 mg/dl; P = 0.03, total cholesterol (−23 ± 5 vs. 10 ± 3 mg/dl; P = 0.01, LDL cholesterol (−20 ± 5 vs. 6 ± 2 mg/dl; P = 0.01, triglyceride (−24 ± 6 vs. −5 ± 2 mg/dl; P = 0.01 and serum CRP (1.31 ± 0.6 vs. 0.33 ± 0.1 mg/l; P = 0.02 concentrations. Significant reductions were also seen in proteinuria (−0.15 ± 0.03 vs. 0.02 ± 0.01 g/day; P = 0.001 and urinary creatinine (−1.5 ± 0.9 vs. 0.6 ± 0.3 mg/dl, P = 0.01 by consumption of soy protein. Conclusion: Long-term soy protein consumption has beneficial effects on cardiovascular risk factors and kidney-related biomarkers among type 2 diabetic patients with nephropathy

    To our knowledge, this study is the first indicating the effects of selenium supplementation on metabolic status of patients with type 2 diabetes mellitus (T2DM) and coronary heart disease (CHD). This study was conducted to evaluate the effects of selenium supplementation on metabolic profiles, biomarkers of inflammation, and oxidative stress of patients with T2DM and CHD. This randomized, double-blind, placebo-controlled trial was performed among 60 patients with T2DM and CHD aged 40-85 years. Participants were randomly divided into 2 groups. Group A received 200 μg selenium supplements (n=30) and group B received placebo per day (n=30) for 8 weeks. Fasting blood samples were taken at the beginning of the study and after 8-week intervention to quantify metabolic profiles. After 8 weeks, compared with the placebo, selenium supplementation resulted in a significant decrease in serum insulin levels (- 2.2±4.6 vs. + 3.6±8.4 μIU/ml, p=0.001), homeostasis model of assessment-insulin resistance (HOMA-IR) (- 0.7±1.3 vs. + 0.9±2.4, p=0.004), homeostatic model assessment-beta cell function (HOMA-B) (- 7.5±17.2 vs. + 15.1±34.5, p=0.002) and a significant increase in quantitative insulin sensitivity check index (QUICKI) (+0.01±0.03 vs. - 0.01±0.03, p=0.02). In addition, patients who received selenium supplements had a significant reduction in serum high-sensitivity C-reactive protein (hs-CRP) (- 1 372.3±2 318.8 vs. - 99.8±1 453.6 ng/ml, p=0.01) and a significant rise in plasma total antioxidant capacity (TAC) concentrations (+ 301.3±400.6 vs. - 127.2±428.0 mmol/l, pselenium supplementation among patients with T2DM and CHD resulted in a significant decrease in insulin, HOMA-IR, HOMA-B, serum hs-CRP, and a significant increase in QUICKI score and TAC concentrations. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available We investigated the associations of injury severity scores (ISSs with the mean platelet volume, the serum levels of two interleukins (IL1β and IL6, and the serum levels of tumour necrosis factor-α (TNFα and C-reactive protein (CRP. We sought to identify biochemical parameters that could be used as components of a new biochemical parameter-based ISS system. The levels of CRP, TNFα, IL1β, and IL6 differed significantly (all p values 0.05. The TNFα and IL6 levels were useful for determining the severity of injury, and the CRP level was elevated in all trauma patients but did not correlate with the ISS. The IL1β level was higher in the study group but did not increase as the ISS increased. IL6 and TNFα levels were higher in the study group and increased as the ISS increased. We found no significant difference between the trauma group and healthy individuals in terms of MPV values. IL6 and TNFα levels can be used to assess trauma severity. However, neither the MPV nor the CRP or IL1β level is useful for this purpose.

    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.

    Background 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. Methods 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. Results 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

    To describe associations between total and regional body fat mass loss and reduction of systemic levels of inflammation (C-reactive protein (CRP) and interleukin-6 (IL-6)) in obese, older adults with osteoarthritis (OA), undergoing intentional weight loss. Data come from a single-blind, 18-month, randomized controlled trial in adults (age: 65.6 ± 6.2; Body mass index (BMI): 33.6 ± 3.7) with knee OA. Participants were randomized to diet-induced weight loss plus exercise (D + E; n = 150), diet-induced weight loss-only (D; n = 149), or exercise-only (E; n = 151). Total body and region-specific (abdomen and thigh) fat mass were measured at baseline and 18 months. High-sensitivity CRP and IL-6 were measured at baseline, six and 18 months. Intervention effects were assessed using mixed models and associations between inflammation and adiposity were compared using logistic and mixed linear regression models. Intentional total body fat mass reduction was associated with significant reductions in log-adjusted CRP (β = 0.06 (95% CI = 0.04, 0.08) mg/L) and IL-6 (β = 0.02 (95% CI = 0.01, 0.04) pg/mL). Loss of abdominal fat volume was also associated with reduced inflammation, independent of total body fat mass; although models containing measures of total adiposity yielded the best fit. The odds of achieving clinically desirable levels of CRP (fat mass loss. Achievement of clinically desirable levels of CRP and IL-6 more than double with intentional 5% loss of total body weight and fat mass. Global, rather than regional, measures of adiposity are better predictors of change in inflammatory burden. NCT00381290. Copyright © 2014 Osteoarthritis Research Society International.

    Some cardiovascular risk factors have been confirmed to be positively correlated with arterial stiffness. However, it is unclear whether HDL-C, a well-established anti-risk factor, has an independent association with arterial stiffness. The aim of this study was to evaluate the relationship between HDL-C levels and arterial stiffness and the possible role of high-sensitivity C-reactive protein (hs-CRP) in this potential correlation in apparently healthy adults undergoing a general health examination in China. This was a cross-sectional survey. In total, 15,302 participants (age range, 18-82 years; mean, 43.88±8.44 years) were recruited during routine health status examinations. A questionnaire was used and we measured the body mass index, systolic and diastolic blood pressure, and fasting glucose, and serum lipid, uric acid, hs-CRP, and serum creatinine levels of each participant. Central arterial stiffness was assessed by carotid-femoral pulse wave velocity (cf-PWV). HDL-C levels decreased as cf-PWV increased. Pearson's correlation analysis revealed that HDL-C levels were associated with cf-PWV (r=-0.18, P<0.001). hs-CRP levels were positively associated with cf-PWV (r=0.13). After adjustment for all confounders, HDL-C was inversely independently associated with all quartiles of cf-PWV. Furthermore, HDL-C was associated with cf-PWV in different quartiles of hs-CRP, and the correlation coefficients (r) gradually decreased with increasing hs-CRP levels (quartiles 1-4). HDL-C is inversely independently associated with central arterial stiffness. The anti-inflammatory activity of HDL-C may mediate its relationship with cf-PWV. Further, long-term follow-up studies are needed to evaluate whether high HDL-C levels are protective against central artery stiffening through the anti-inflammatory activity of HDL-C.

    Grassland passerines were surveyed during summer 1995 on the Buffalo Ridge Wind Resource Area in southwestern Minnesota to determine the relative influence of wind turbines on overall densities of upland nesting birds in Conservation Reserve Program (CRP) grasslands. Birds were surveyed along 40 m fixed width transects that were placed along wind turbine strings within three CRP fields and in three CRP fields without turbines. Conservation Reserve Program grasslands without turbines and areas located 180 m from turbines supported higher densities (261.0-312.5 males/100 ha) of grassland birds than areas within 80 m of turbines (58.2-128.0 males/100 ha). Human disturbance, turbine noise, and physical movements of turbines during operation may have disturbed nesting birds. We recommend that wind turbines be placed within cropland habitats that support lower densities of grassland passerines than those found in CRP grasslands.

    Full Text Available Previously, artesunate (AS and dihydroartemisinine 7 (DHA7 were found to have antibacterial enhancement activity against Escherichia coli via inhibition of the efflux pump AcrB. However, they were only effective against E. coli standard strains. This study aimed to develop effective antibacterial enhancers based on the previous work. Our results demonstrate that 86 new antibacterial enhancers were designed via 3D-SAR and molecular docking. Among them, DHA27 had the best antibacterial enhancement activity. It could potentiate the antibacterial effects of ampicillin against not only E. coli standard strain but also clinical strains, and of β-lactam antibiotics, not non-β-lactamantibiotics. DHA27 could increase the accumulation of daunomycin and nile red within E. coli ATCC 35218, but did not increase the bacterial membrane permeability. DHA27 reduced acrB’s mRNA expression of E. coli ATCC 35218 in a dose-dependent manner, and its antibacterial enhancement activity is related to the degree of acrB mRNA expression in E. coli clinical strains. The polypeptides from AcrB were obtained via molecular docking assay; the pre-incubated polypeptides could inhibit the activity of DHA27. Importantly, DHA27 had no cytotoxicity on cell proliferation. In conclusion, among newly designed antibacterial enhancers, DHA27 had favorable physical and pharmacological properties with no significant cytotoxicity at effective concentrations, and might serve as a potential efflux pump inhibitor in the future.

    In regard with the effect of immune-stimulants in the treatment of infectious diseases, the effect of vitamin D administration on the outcome of patients with Ventilator-Associated Pneumonia (VAP) with a high rate of mortality, was studied. In this trial, 46 adult patients suffering from VAP and vitamin D deficiency were enrolled. The first group of patients received single intramuscular injection of vitamin D (300000Unit), while the other group were given the placebo. Administration of vitamin D significantly enhanced its levels (P<0.0001) in the treated patients (12.28±8.26) in comparison with placebo group (1.15±1.50). Serum Interleukin-6 levels were significantly reduced in the treated group compared to placebo (P=0.01). Although C-Reactive protein (CRP) levels showed an improving trend in the vitamin D group, no significant difference between groups (P=0.12) was found. Interestingly, the mortality rate of patients that treated with vitamin D (5/24) was significantly lower (p=0.04) than that of the placebo group (11/22). Our results indicate that vitamin D administration can significantly reduce the IL-6 as prognostic marker in VAP patients, and must be considered as adjunct option in the treatment of VAP patients.

    This document provides a summary of a review of the performance of bioinjection activities at the Building 100 Area and the 4.5 Acre Site at the Pinellas County, Florida, Site since 2010, determines how best to optimize future injection events, and identifies the approach for the bioinjection event in 2016 at (1) the 4.5 Acre Site and (2) the Essentra property at the Building 100 Area. Because this document describes the next bioinjection event at the 4.5 Acre Site, it also serves as an addendum to the Interim Remedial Action Plan for Emulsified Edible Oil Injection at the 4.5 Acre Site (DOE 2013). In addition, this document revises the injection layout and injection intervals for the Essentra property that were originally described in the Interim Corrective Measure Work Plan for Source and Plume Treatment at the Building 100 Area (DOE 2014), and is a de facto update of that document. Bioinjection consists of injection of emulsified vegetable oil (EVO) and the microorganism Dehalococcoides mccartyi (DHM; formerly known as Dehalococcoides ethenogenes) into the subsurface to enhance biodegradation of trichloroethene (TCE), dichloroethene (DCE), and vinyl chloride (VC). VC is the only contaminant that exceeds its maximum contaminant level (10 micrograms per liter onsite and 1 microgram per liter onsite) on the 4.5 Acre Site and the Essentra property. Bioinjection was conducted at the 4.5 Acre Site in 2010 and 2013. Approximately 49,900 gallons of EVO and DHM were injected at 95 injection points in February 2010, and approximately 22,900 gallons of EVO and DHM were injected at 46 injection points in July 2013. The injection locations are shown on Figure 1. The goal of bioinjection at the 4.5 Acre Site is to decrease contaminant concentrations to maximum contaminant levels along the west and southwest property boundaries (to meet risk–based corrective action requirements) and to minimize the extent of the contaminant plume in the interior of the site. Bioinjection was

    The Cretaceous Green Acres layered igneous complex, northeast of Winchester, California, is composed of a suite of olivine- and hornblende-bearing gabbros in the Peninsular Ranges batholith within the Perris tectonic block. A consistent mineral assemblage is observed throughout the complex, but there is considerable textural and modal heterogeneity. Both preclude a consistent set of principles based on appearance and mineralogy on which to delineate map units. Distinct changes in the chemistry of olivine, pyroxene, and hornblende, however, serve to define discrete mappable units, and the complex has been divided into five geochemical map units on this basis.Limited whole-rock data show the Green Acres complex is chemically comparable to other Peninsular Ranges batholith gabbroic rocks, and rare earth element (REE) concentrations and patterns are typical of magmas generated in convergent margin settings. For the complex as a whole, olivine is Fo80–35, plagioclase is An100–64, clinopyroxene is Wo49–41En48–38Fs18–6 and Wo36–26En65–42Fs30–8, and orthopyroxene is Wo5–0En78–42Fs50–21, where Fo is forsterite, An is anorthite, Wo is wollastonite, En is enstatite, and Fs is ferrosilite. The Mg/(Mg + ΣFe) atomic ratio in hornblende ranges from 0.84 to 0.50.Magmatic lineations and modal and textural layering are prevalent throughout the complex. Mineral chemistry does not change in any systematic way within and between layers in any map unit. Although the strike of layering varies, in any map unit at any given location it is the same in all units irrespective of intrusive order. Thin dikes, typically late-stage hornblende gabbro, commonly intrude parallel to layering. The strikes of magmatic lineations and modal layers are consistent with the populations of strikes of fabrics in the metamorphic basement as well as tectonic features in surrounding, postgabbro granitic rocks. These relations imply that the regional state of stress at the time of gabbro

    Soil-transmitted helminth infections in humans and livestock cause significant debility, reduced productivity and economic losses globally. There are a limited number of effective anthelmintic drugs available for treating helminths infections, and their frequent use has led to the development of resistance in many parasite species. There is an urgent need for novel therapeutic drugs for treating these parasites. We have chosen the ACR-16 nicotinic acetylcholine receptor of Ascaris suum (Asu-ACR-16), as a drug target and have developed three-dimensional models of this transmembrane protein receptor to facilitate the search for new bioactive compounds. Using the human α7 nAChR chimeras and Torpedo marmorata nAChR for homology modeling, we defined orthosteric and allosteric binding sites on the Asu-ACR-16 receptor for virtual screening. We identified four ligands that bind to sites on Asu-ACR-16 and tested their activity using electrophysiological recording from Asu-ACR-16 receptors expressed in Xenopus oocytes. The four ligands were acetylcholine inhibitors (SB-277011-A, IC50, 3.12 ± 1.29 μM; (+)-butaclamol Cl, IC50, 9.85 ± 2.37 μM; fmoc-1, IC50, 10.00 ± 1.38 μM; fmoc-2, IC50, 16.67 ± 1.95 μM) that behaved like negative allosteric modulators. Our work illustrates a structure-based in silico screening method for seeking anthelmintic hits, which can then be tested electrophysiologically for further characterization.

    We present the experimental ELNES spectra of the Cr-L{sub 2,3} and O-K edges in three high pressure synthesized perovskites, ACrO{sub 3} (A = Ca, Sr and Pb). A comparison of the experimental spectra against the theoretical calculations shows the influence of the A cation in the features of the spectrum. The Cr-L{sub 2,3} multiplet structure of these perovskites shows similar integrated intensity ratio ({integral} I{sub L3}/{integral} I{sub L2}) between them and with the CrO{sub 2}, implying that all of them are indeed composed by Cr{sup 4+}. But the O-K pre-edge observed in CrO{sub 2}, typical of its d{sup 3}L character (L-ligand hole), is not present in these perovskites. The effect of the A cation manifests itself in the O-K edge. The different features in the peak edges are caused by the change in the interaction between oxygen and the A cation from being via p orbitals (with Pb) to being via d orbitals (with Ca, Sr). The experimental spectra of the samples are reproduced well by the presented DFT calculations.

    Dynamical properties of the lattice structure were studied by optical spectroscopy in ACr2O4 chromium spinel oxide magnetic semiconductors over a broad temperature region of T=10-335 K. The systematic change of the A-site ions (A= Mn, Fe, Co, Ni and Cu) showed that the occupancy of 3d orbitals on the A site has strong impact on the lattice dynamics. For compounds with orbital degeneracy (FeCr2O4, NiCr2O4, and CuCr2O4), clear splitting of infrared-active phonon modes and/or activation of silent vibrational modes have been observed upon the Jahn-Teller transition and at the onset of the subsequent long-range magnetic order. Although MnCr2O4 and CoCr2O4 show multiferroic and magnetoelectric character, no considerable magnetoelasticity was found in spinel compounds without orbital degeneracy as they closely preserve the high-temperature cubic spinel structure even in their magnetic ground state. Aside from lattice vibrations, intra-atomic 3d-3d transitions of the A2+ ions were also investigated to determine the crystal field and Racah parameters and the strength of the spin-orbit coupling.

    Full Text Available Background and Aim: Commuting by bicycle could contribute to public health, and route environments may influence this behaviour. Therefore, the aim of this study is to assess the potential associations between appraisals of the overall route environment as hindering or stimulating for bicycle commuting, with both perceptions of commuting route environmental factors in a suburban area and background factors. Methods: The Active Commuting Route Environment Scale (ACRES was used for the assessment of bicycle commuters’ perceptions and appraisals of their route environments in the suburban parts of Greater Stockholm, Sweden. A simultaneous multiple regression analysis was used to assess the relationship between the outcome variable whether the overall route environment hinders or stimulates bicycle commuting and environmental factors (e.g., exhaust fumes, speeds of motor vehicles, greenery, as well as background factors (sex, age, education, income as predictor variables. Results and Conclusions: The results indicate that in suburban areas, the factors aesthetics, greenery and bicycle paths seem to be, independently of each other, stimulating factors for bicycle commuting. On the other hand, flows of motor vehicles, noise, and low “directness” of the route seem to be hindering factors. A comparison of these results with those obtained from an inner urban area points to the importance of studying different types of built-up areas separately.

    In the mid-1980`s, the movement toward the use of dedicated mammography equipment provided significant improvement in breast cancer detection. However, several studies demonstrated that this change was not sufficient to ensure optimal image quality at a low radiation dose. In particular, the 1985 Nationwide Evaluation of X-ray Trends identified the wide variations in image quality and radiation dose, even from dedicated units. During this time period, the American Cancer Society (ACS) launched its Breast Cancer Awareness Screening Campaign. However, there were concerns about the ability of radiology to respond to the increased demand for optimal screening examinations that would result from the ACS program. To respond to these concerns, the ACS and the American College of Radiology (ACR) established a joint committee on mammography screening in 1986. After much discussion, it was decided to use the ACR Diagnostic Practice Accreditation Program as a model for the development of a mammography accreditation program. However, some constraints were required in order to make the program meet the needs of the ACS. This voluntary, peer review program had to be timely and cost effective. It was determined that the best way to address these needs would be to conduct the program by mail. Finally, by placing emphasis on the educational nature of the program, it would provide an even greater opportunity for improving mammographic quality. The result of this effort was that, almost six years ago, in May 1987, the pilot study for the ACR Mammography Accreditation Program (MAP) began, and in August of that year, the first applications were received. In November 1987, the first 3-year accreditation certificates were awarded.

No significant difference was observed with regard to triglycerides, HDL-cholesterol, and safety parameters. On the basis of our data, we could demonstrate that a 10 mg monacolin nutraceutical treatment appears to safely reduce cholesterolemia, hs-CRP, and markers of vascular remodeling in moderately

    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.

    SLE is traditionally classified using the American College of Rheumatology (ACR) criteria. The Systemic Lupus International Collaborating Clinics (SLICC) recently validated an alternative system. This study examined large cohorts of subjects with SLE and incomplete lupus erythematosus (ILE) to compare the impact of ACR and SLICC criteria. Medical records of subjects in the Lupus Family Registry and Repository were reviewed for documentation of 1997 ACR classification criteria, SLICC classification criteria and medication usage. Autoantibodies were assessed by indirect immunofluorescence (ANA, antidouble-stranded DNA), precipitin (Sm) and ELISA (anticardiolipin). Other relevant autoantibodies were detected by precipitin and with a bead-based multiplex assay. Of 3575 subjects classified with SLE under at least one system, 3312 (92.6%) were classified as SLE by both systems (SLE(both)), 85 only by ACR criteria (SLE(ACR-only)) and 178 only by SLICC criteria (SLE(SLICC-only)). Of 440 subjects meeting 3 ACR criteria, 33.9% (149/440) were SLE(SLICC-only), while 66.1% (n=291, designated ILE) did not meet the SLICC classification criteria. Under the SLICC system, the complement criterion and the individual autoantibody criteria enabled SLE classification of SLE(SLICC-only) subjects, while SLE(ACR-only) subjects failed to meet SLICC classification due to the combined acute/subacute cutaneous criterion. The SLICC criteria classified more African-American subjects by the leucopenia/lymphopenia criterion than did ACR criteria. Compared with SLE(ACR-only) subjects, SLE(SLICC-only) subjects exhibited similar numbers of affected organ systems, rates of major organ system involvement (∼30%: pulmonary, cardiovascular, renal, neurological) and medication history. The SLICC criteria classify more subjects with SLE than ACR criteria; however, individuals with incomplete lupus still exist under SLICC criteria. Subjects who gain SLE classification through SLICC criteria exhibit

    Multidrug efflux protein complexes such as AcrAB-TolC from Escherichia coli are paramount in multidrug resistance in Gram-negative bacteria and are also implicated in other processes such as virulence and biofilm formation. Hence efflux pump inhibition, as a means to reverse antimicrobial resistance in clinically relevant pathogens, has gained increased momentum over the past two decades. Significant advances in the structural and functional analysis of AcrB have informed the selection of efflux pump inhibitors (EPIs). However, an accurate method to determine the kinetics of efflux pump inhibition was lacking. In this study we standardised and optimised surface plasmon resonance (SPR) to probe the binding kinetics of substrates and inhibitors to AcrB. The SPR method was also combined with a fluorescence drug binding method by which affinity of two fluorescent AcrB substrates were determined using the same conditions and controls as for SPR. Comparison of the results from the fluorescent assay to those of the SPR assay showed excellent correlation and provided validation for the methods and conditions used for SPR. The kinetic parameters of substrate (doxorubicin, novobiocin and minocycline) binding to AcrB were subsequently determined. Lastly, the kinetics of inhibition of AcrB were probed for two established inhibitors (phenylalanine arginyl β-naphthylamide and 1-1-naphthylmethyl-piperazine) and three novel EPIs: 4-isobutoxy-2-naphthamide (A2), 4-isopentyloxy-2-naphthamide (A3) and 4-benzyloxy-2-naphthamide (A9) have also been probed. The kinetic data obtained could be correlated with inhibitor efficacy and mechanism of action. This study is the first step in the quantitative analysis of the kinetics of inhibition of the clinically important RND-class of multidrug efflux pumps and will allow the design of improved and more potent inhibitors of drug efflux pumps.

    Weather observations and reanalysis are perfect partners: the observations make the reanalysis possible, and the reanalysis makes optimal use of the observations in producing the comprehensive picture of the atmosphere required by both climate scientists and a host of other users. The new generation of surface-input-only reanalyses (20th Century Reanalysis Project: 1891-2006, 20th Century Reanalysis Project: 1871-2008, Surface Input Reanalysis for Climate Applications [SIRCA]: 1850-2011 and Chemical and Surface Input Reanalysis for Climate Applications [CSIRCA]: 1800-2016) therefore present both a challenge and an opportunity to observations specialists: they require an unprecedented increase in the available datasets of surface barometric pressure, sea surface temperature and sea-ice; but offer a chance to synthesise terrestrial and marine observations into a much more detailed picture of climate variability and change. The international Atmospheric Circulation Reconstructions over the Earth (ACRE) initiative is supporting this work, both undertaking and facilitating the global recovery, imaging, digitizing, quality control and archiving of daily to sub-daily global historical terrestrial and marine surface weather observations. In this presentation, we provide an overview of the international historical terrestrial and marine data activities required to produce the quality and quantity of weather data needed in order to undertake viable historical surface-input-only historical reanalyses, ultimately extending back over the last 200 or so years. This endeavor has only been made possible because of ACRE's efforts to agglomerate a combination of the results of ongoing international data recovery initiatives, some as existing data rescue projects, and other new initiatives focusing on particular regions or countries around the world. Numerous elements and interactions are involved in such a vast enterprise, with careful consideration required in working with

    Inflammatory mechanism appears to play a major role in the pathogenesis of various types of human pulmonary hypertension such as idiopathic PAH (IPAH) and PAH associated" with connective tissue disease. Although we know that inflammatory factors such as IL6 and TNFα have an important role in IPAH, there is limited information about the relationship between acute phase reactants and pulmonary hypertension occurring secondary to pulmonary diseases such as chronic obstructive pulmonary diseases (COPD). This cross-sectional study was carried out on 94 patients who had COPD. Patients with a recent history of systemic steroid and acetylsalicylic acid (ASA) use, infection, trauma or surgery, gastrointestinal bleeding, coronary artery disease (CAD) and Hypertension were excluded. Body plethysmography and transthoracic echocardiography were done. Blood samples for each patient included were drawn for complete blood count (CBC), IL6, TNFα and highly sensitive C reactive protein (hs-CRP). Twenty patients (28.6%) had pulmonary hypertension. The difference between the mean IL6 and hs-CRP in patients with and without pulmonary hypertension was significant (7 pg/ml vs. 4.4 pg/ml and 13.04 pg/ml vs. 3.31 pg/ml) (p=0.006 and p=0.000). There was a correlation between IL6 and mean pulmonary arterial pressure (r=0.35, p=0.003). After adjustment forage, sex, serum Hemoglobin, Hematocrit, O2Sat, FEV1, FVC the relationship between the IL6, hs-CRP and the presence of pulmonary hypertension remained significant (p=0.022, p=0.026). Inflammatory factors such as IL6 and hs-CRP are independent risk factors for pulmonary hypertension in COPD patients.

    Previous studies investigating flavanol-rich foods provide indications for potential cardioprotective effects of these foods, but the effects of individual flavanols remain unclear. We investigated whether the flavanol epicatechin can reduce diet-induced atherosclerosis, with particular emphasis on the cardiovascular risk factors dyslipidaemia and inflammation. ApoE*3-Leiden mice were fed a cholesterol-containing atherogenic diet with or without epicatechin (0.1% w/w) to study effects on early- and late-stage atherosclerosis (8 w and 20 w). In vivo effects of epicatechin on diet-induced inflammation were studied in human-CRP transgenic mice and NFκB-luciferase reporter mice. Epicatechin attenuated atherosclerotic lesion area in ApoE*3-Leiden mice by 27%, without affecting plasma lipids. This anti-atherogenic effect of epicatechin was specific to the severe lesion types, with no effect on mild lesions. Epicatechin mitigated diet-induced increases in plasma SAA (in ApoE*3-Leiden mice) and plasma human-CRP (in human-CRP transgenic mice). Microarray analysis of aortic gene expression revealed an attenuating effect of epicatechin on several diet-induced pro-atherogenic inflammatory processes in the aorta (e.g. chemotaxis of cells, matrix remodelling), regulated by NFκB. These findings were confirmed immunohistochemically by reduced lesional neutrophil content in HCE, and by inhibition of diet-induced NFκB activity in epicatechin-treated NFκB-luciferase reporter mice. Epicatechin attenuates development of atherosclerosis and impairs lesion progression from mild to severe lesions in absence of an effect on dyslipidaemia. The observed reduction of circulating inflammatory risk factors by epicatechin (e.g. SAA, human-CRP), as well as its local anti-inflammatory activity in the vessel wall, provide a rationale for epicatechin's anti-atherogenic effects.

    The Amazon region has the highest seroprevalence of hepatitis A virus (HAV) in Brazil. In the present study, the seroprevalence of total HAV antibodies in two groups, composed of 147 and 254 children between 1 and 5 years old in Assis Brasil, Acre, was measured in 2003 and 2010, respectively, and compared with socio-economic changes in the city. In 2003, the HAV seroprevalence rate was 26.5%, while in 2010, it was 22.4%. There was an overall improvement in socio-economic and sanitary conditions, with the exception of open sewage. In 2003, factors associated with positive serology were child age (aOR [adjusted odds ratio] 1.84; 95% CI: 1.28-2.64), having a latrine or not having a toilet at home (aOR 4.73; 95% CI: 1.06-21.17) and the treatment of drinking water with chlorine (aOR 0.26; 95% CI: 0.07-0.92). In 2010, the main factors associated with positive serology were using rivers, streams and rainwater as sources of water for domestic purposes (aOR 24.36; 95% CI: 3.69-160.85); having a wooden or ground floor at home (OR 2.51; 95% CI: 1.11-5.69) and child age (aOR 2.33; 95% CI: 1.66-3.28). In the Brazilian Amazon, sanitation and water treatment still require improvement and socio-economic development is warranted in order to decrease hepatitis A transmission. © The Author 2015.

    To report clinical manifestations and demographic characteristics of patients with rheumatic fever treated in a public hospital in the state of Acre. A cross-sectional study was conducted of patients consecutively seen in the Cardiology Ward at FUNDHACRE Demographic, clinical and laboratory data were assessed through a questionnaire. The diagnosis of rheumatic fever was made based on Jones' criteria, associated with laboratory data, electrocardiography, chest X-ray, and bi-dimensional echocardiography. Patients with other heart diseases, diabetes, obesity, inflammatory disease, and infections were excluded. Those who smoked, were pregnant, or used anti-inflammatory medication or hormone therapy were also excluded. From July 2003 to February 2004, 99 patients with rheumatic fever were assessed (mean age, 11 years, SD= +/- 10.18) with a predominance of females (59.6%), and a racial phenotype of a mixture of Caucasian and Indian (60.6%). Three individuals were excluded because they did not meet the diagnostic criteria. Mean age was 9.1 years old, and in 30.4% of the patients, the disease was diagnosed at the first episode of rheumatic fever. The most frequent clinical manifestations were carditis (69.7%), arthritis (21.4%), and chorea (6.1%). Mitral regurgitation was the most common lesion (36.4%) followed by the association of mitral regurgitation and aortic regurgitation (9.1%). Rheumatic carditis was the most common manifestation of rheumatic fever, predominant in the group with a racial mixture of Caucasian and Indian (60.6%). Low compliance with antibiotic therapy contributed to the recurrence of the disease and to cardiac sequelae.

    Boston's newly constructed Central Artery Tunnel (CAT) Project replaced a six-lane elevated highway with an eight-to-ten lane underground expressway directly beneath the existing road. The $14.6 billion dollar project has proven to be one of the largest, most technically and environmentally challenging infrastructure projects ever undertaken in the United States. It spans 7.8 miles of highway. The roof deck of the CAT project, commonly referred to as the Big Dig, will support a 30 parkway systems with a cross section typical of an intensive green roof. The 300 acre open urban space, formerly known as the Rose Kennedy Greenway, will include 45 parks and major public plazas. This paper reviewed the technology that supports the open space, with reference to the materials and techniques used in green roof projects, namely waterproofing, protection board, reservoir layers, planting medium, and plant material to support a layer of green over occupied spaces. The structural integrity of the tunnel decking allows for a wide variety of plant installations on the Big Dig. The installations range from open lawn areas with a 6 inch layer of planting medium. Planting beds for shrubs and perennials require up to 24 inches of planting medium. All areas over the tunnel are covered with enough structural soil to allow for root growth. All plant installations are irrigated with an underdrainage system connected to drain lines. Details of the structural soil material were presented along with a list of plants and trees species used in the landscape design. 8 figs.

    Full Text Available Palm heart constitutes a major non-timber forest product within the pro poor development strategy in Acre State. The 1990s it witnessed a boom of native palm processing, that proved to be unsustainable and processing units migrated to northern Bolivia. This article aims to rescue the impacts of this process, and subsequent initiatives of peach palm cultivation, originated by public and private, which, however, experienced difficulties to access the market. Given the scarce bibliography on the topic, we seek to contribute to the debate of this productive chain in Acre as an input to the debate on strategies to support the marketing of non-wood forest products, essential to the state’s policy of providing value to the standing forest.

    There is increasing recognition of association of nonalcoholic fatty liver disease (NAFLD) with cardiovascular disease (CVD). Metabolic syndrome is common in both NAFLD and cardiovascular diseases. Our study is designed to investigate the association of NAFLD with cardiovascular disease. It's a cross-sectional study which included 104 patients of coronary artery disease and hypertensive heart disease. Those patients having secondary causes of steatosis were excluded. Complete cardiovascular evaluation which included assessment of metabolic syndrome, routine biochemistries, viral markers, Ultrasonography (USG) abdomen, hs-CRP and TNF-α levels were obtained for all patients. Of all patients with cardiovascular disease, 19.2% (20/104) had essential hypertension with hypertensive heart disease the remaining 80.8% (84/104) patients had ischemic heart disease (IHD). On USG 69.2% (72/104) had NAFLD, these 50% (36/72) had grade 1 NAFLD and the rest grade 2 NAFLD. The hs-CRP levels and TNF-α were significantly higher in patients with NAFLD (p-value cardiovascular disease (69.2%) and is significantly associated with metabolic syndrome and its individual components. The levels of hs-CRP and TNF-α were significantly higher in patients with NAFLD and showed an increasing trend with the severity of fatty liver. Copyright © 2014 Cardiological Society of India.

    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. PMID:23469212

    LmACR2 from L. major is the first rhodanese-like enzyme directly involved in the reduction of arsenate and antimonate to be crystallized. Diffraction data have been collected to 1.99 Å resolution using synchrotron X-rays. Arsenic is present in the biosphere owing either to the presence of pesticides and herbicides used in agricultural and industrial activities or to leaching from geological formations. The health effects of prolonged exposure to arsenic can be devastating and may lead to various forms of cancer. Antimony(V), which is chemically very similar to arsenic, is used instead in the treatment of leishmaniasis, an infection caused by the protozoan parasite Leishmania sp.; the reduction of pentavalent antimony contained in the drug Pentostam to the active trivalent form arises from the presence in the Leishmania genome of a gene, LmACR2, coding for the protein LmACR2 (14.5 kDa, 127 amino acids) that displays weak but significant sequence similarity to the catalytic domain of Cdc25 phosphatase and to rhodanese enzymes. For structural characterization, LmACR2 was overexpressed, purified to homogeneity and crystallized in a trigonal space group (P321 or P3{sub 1}21/P3{sub 2}21). The protein crystallized in two distinct trigonal crystal forms, with unit-cell parameters a = b = 111.0, c = 86.1 Å and a = b = 111.0, c = 175.6 Å, respectively. At a synchrotron beamline, the diffraction pattern extended to a resolution limit of 1.99 Å.

    The dopamine D2 receptor (D2R) plays an important part in the human central nervous system and it is considered to be a focal target of antipsychotic agents. It is structurally modeled in active and inactive states, in which homodimerization reaction of the D2R monomers is also applied. The ASP2314 (also known as ACR16) ligand, a D2R stabilizer, is used in tests to evaluate how dimerization and conformational changes may alter the ligand binding space and to provide information on alterations in inhibitory mechanisms upon activation. The administration of the D2R agonist ligand ACR16 [ 3 H](+)-4-propyl-3,4,4a,5,6,10b-hexahydro-2H-naphtho[1,2-b][1,4]oxazin-9-ol ((+)PHNO) revealed K i values of 32 nM for the D2 high R and 52 μM for the D2 low R. The calculated binding affinities of ACR16 with post processing molecular dynamics (MD) simulations analyses using MM/PBSA for the monomeric and homodimeric forms of the D2 high R were -9.46 and -8.39 kcal/mol, respectively. The data suggests that the dimerization of the D2R leads negative cooperativity for ACR16 binding. The dimerization reaction of the D2 high R is energetically favorable by -22.95 kcal/mol. The dimerization reaction structurally and thermodynamically stabilizes the D2 high R conformation, which may be due to the intermolecular forces formed between the TM4 of each monomer, and the result strongly demonstrates dimerization essential for activation of the D2R.

    Arsenic contamination of groundwater sources is a major issue worldwide, since exposure to high levels of arsenic has been linked to a variety of health problems. Effective methods of detection are thus greatly needed as preventive measures. In an effort to develop a fungal biosensor for arsenic, we first identified seven putative arsenic metabolism and transport genes in Aspergillus niger, a widely used industrial organism that is generally regarded as safe (GRAS). Among the genes tested for RNA expression in response to arsenate, acrA, encoding a putative plasma membrane arsenite efflux pump, displayed an over 200-fold increase in gene expression in response to arsenate. We characterized the function of this A. niger protein in arsenic efflux by gene knockout and confirmed that AcrA was located at the cell membrane using an enhanced green fluorescent protein (eGFP) fusion construct. Based on our observations, we developed a putative biosensor strain containing a construct of the native promoter of acrA fused with egfp. We analyzed the fluorescence of this biosensor strain in the presence of arsenic using confocal microscopy and spectrofluorimetry. The biosensor strain reliably detected both arsenite and arsenate in the range of 1.8 to 180 μg/liter, which encompasses the threshold concentrations for drinking water set by the World Health Organization (10 and 50 μg/liter).

    Because CRP is a strong independent predictor of various diseases, it was hypothesized that CRP may be a useful predictor or treatment target for medical-care expenditures. The aim of this study was to investigate the relationship between CRP and medical-care expenditures in a community-dwelling elderly population. This prospective cohort study was conducted including 925 Japanese subjects aged ≥70 years. A high-sensitivity CRP assay was used by applying the nephelometric method. Hospitalizations, outpatient visits, and expenditures were ascertained through computerized linkage with claims lodged between August 2002 and March 2008 with the Miyagi National Health Insurance (NHI) Association. Since medical-care expenditures were not normally distributed, the category of high medical-care expenditures (>75th percentile of medical-care expenditures: inpatient expenditures >$494/month; outpatient expenditure >$522/month; total expenditures >$1103/month) was used to examine the relation of CRP levels with medical-care expenditures. Multiple logistic regression analysis was used to examine the relationship between CRP cutoff points (low concentrations: community-dwelling elderly. Further study is required to clarify whether reducing CRP by intervention is a cost-effective measure. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    The need for a defendable and systematic uncertainty and sensitivity approach that conforms to the Code Scaling, Applicability, and Uncertainty (CSAU) process, and that could be used for a wide variety of software codes, was defined in 2008. The GRS (Gesellschaft für Anlagen und Reaktorsicherheit) company of Germany has developed one type of CSAU approach that is particularly well suited for legacy coupled core analysis codes, and a trial version of their commercial software product SUSA (Software for Uncertainty and Sensitivity Analyses) was acquired on May 12, 2010. This report summarized the results of the initial investigations performed with SUSA, utilizing a typical High Temperature Reactor benchmark (the IAEA CRP-5 PBMR 400MW Exercise 2) and the PEBBED-THERMIX suite of codes. The following steps were performed as part of the uncertainty and sensitivity analysis: 1. Eight PEBBED-THERMIX model input parameters were selected for inclusion in the uncertainty study: the total reactor power, inlet gas temperature, decay heat, and the specific heat capability and thermal conductivity of the fuel, pebble bed and reflector graphite. 2. The input parameters variations and probability density functions were specified, and a total of 800 PEBBED-THERMIX model calculations were performed, divided into 4 sets of 100 and 2 sets of 200 Steady State and Depressurized Loss of Forced Cooling (DLOFC) transient calculations each. 3. The steady state and DLOFC maximum fuel temperature, as well as the daily pebble fuel load rate data, were supplied to SUSA as model output parameters of interest. The 6 data sets were statistically analyzed to determine the 5% and 95% percentile values for each of the 3 output parameters with a 95% confidence level, and typical statistical indictors were also generated (e.g. Kendall, Pearson and Spearman coefficients). 4. A SUSA sensitivity study was performed to obtain correlation data between the input and output parameters, and to identify the

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

    Directory of Open Access Journals (Sweden)

    Stephan P Willias

    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

  15. Relationships between HDL-C, hs-CRP, with central arterial stiffness in apparently healthy people undergoing a general health examination.

    Full Text Available BACKGROUND: Some cardiovascular risk factors have been confirmed to be positively correlated with arterial stiffness. However, it is unclear whether HDL-C, a well-established anti-risk factor, has an independent association with arterial stiffness. The aim of this study was to evaluate the relationship between HDL-C levels and arterial stiffness and the possible role of high-sensitivity C-reactive protein (hs-CRP in this potential correlation in apparently healthy adults undergoing a general health examination in China. MATERIALS AND METHODS: This was a cross-sectional survey. In total, 15,302 participants (age range, 18-82 years; mean, 43.88±8.44 years were recruited during routine health status examinations. A questionnaire was used and we measured the body mass index, systolic and diastolic blood pressure, and fasting glucose, and serum lipid, uric acid, hs-CRP, and serum creatinine levels of each participant. Central arterial stiffness was assessed by carotid-femoral pulse wave velocity (cf-PWV. RESULTS: HDL-C levels decreased as cf-PWV increased. Pearson's correlation analysis revealed that HDL-C levels were associated with cf-PWV (r=-0.18, P<0.001. hs-CRP levels were positively associated with cf-PWV (r=0.13. After adjustment for all confounders, HDL-C was inversely independently associated with all quartiles of cf-PWV. Furthermore, HDL-C was associated with cf-PWV in different quartiles of hs-CRP, and the correlation coefficients (r gradually decreased with increasing hs-CRP levels (quartiles 1-4. CONCLUSIONS: HDL-C is inversely independently associated with central arterial stiffness. The anti-inflammatory activity of HDL-C may mediate its relationship with cf-PWV. Further, long-term follow-up studies are needed to evaluate whether high HDL-C levels are protective against central artery stiffening through the anti-inflammatory activity of HDL-C.

    The radiology job market remains daunting. Trainees choosing fellowships benefit from understanding employers' likely future needs. Radiology practices may similarly refine recruiting practices. This study quantitatively analyzes the current radiology job landscape. Job postings on the ACR Career Center online portal between June 2014 and June 2015 were reviewed. As entries are frequently added and removed, posts were manually collected weekly. Postings were recorded in a database and included date, practice, location, specialty/subspecialty, job type, years of experience, salary, and job description. The database was analyzed to characterize employer needs, salary, partnership track availability, and job availability by geography. A total of 1,778 jobs were posted during the study period. Of these, 1,529 (86.0%) were diagnostic; 240 (13.5%) were interventional; and 9 (0.5%) were administrative. Most jobs were in private practice (75.7%), compared with academic (16.3%) and other (7.9%). Although many did not require a specific specialty (46%), the most-frequent needs were breast (17%), neuroradiology (11%), musculoskeletal (8%), and body (7%). Of non-breast-imaging jobs, roughly 30% indicated an interest in breast-imaging skills. A minority (13%) requested prior experience of greater than 1 year, with some seeking 7-10 years of experience. Although most (87%) were full-time positions, part-time, temporary, and contractor roles were described in the remaining 13%. Salary data were rarely reported (7%), with a range of $98,967-$1,000,000. The most jobs were based in California (11%); New York (7%); Pennsylvania (7%); and Illinois (6%). However, when indexed per million population, the highest job rates were in Nevada (14.1); Washington DC (13.7); Hawaii (13.4); Montana (9.8); and Pennsylvania (9.1). Roughly 31% of postings described partnership tracks, with the highest rates in New England (58%), the Pacific Northwest (56%), the Midwest (40%), and Southern (40

    Transperineal permanent prostate brachytherapy is a safe and efficacious treatment option for patients with organ-confined prostate cancer. Careful adherence to established brachytherapy standards has been shown to improve the likelihood of procedural success and reduce the incidence of treatment-related morbidity. A collaborative effort of the American College of Radiology (ACR) and American Society for Therapeutic Radiation Oncology (ASTRO) has produced a practice guideline for permanent prostate brachytherapy. The guideline defines the qualifications and responsibilities of all the involved personnel, including the radiation oncologist, physicist and dosimetrist. Factors with respect to patient selection and appropriate use of supplemental treatment modalities such as external beam radiation and androgen suppression therapy are discussed. Logistics with respect to the brachytherapy implant procedure, the importance of dosimetric parameters, and attention to radiation safety procedures and documentation are presented. Adherence to these practice guidelines can be part of ensuring quality and safety in a successful prostate brachytherapy program.

    Multidrug transcription regulator AcrR from Salmonella enterica subsp. enterica serovar Typhimurium str. LT2 belongs to the tetracycline repressor family, one of the largest groups of bacterial transcription factors. The crystal structure of dimeric AcrR was determined and refined to 1.56 Å resolution. The tertiary and quaternary structures of AcrR are similar to those of its homologs. The multidrug binding site was identified based on structural alignment with homologous proteins and has a di(hydroxyethyl)ether molecule bound. Residues from helices a4 and a7 shape the entry into this binding site. The structure of AcrR reveals that the extended helical conformation of helix a4 is stabilized by the hydrogen bond between Glu67 (helix a4) and Gln130 (helix a7). Based on the structural comparison with the closest homolog structure, the Escherichia coli AcrR, we propose that this hydrogen bond is responsible for control of the loop-to-helix transition within helix a4. This local conformational switch of helix a4 may be a key step in accessing the multidrug binding site and securing ligands at the binding site. Solution smallmolecule binding studies suggest that AcrR binds ligands with their core chemical structure resembling the tetracyclic ring of cholesterol.

    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.

    To observe the effect and explore the action mechanism of Danhong Injection (DHI) on serum levels of endothelin-1 (ET-1), soluble P-selectin (sP-sel) and high sensitivity C-reactive protein (hs-CRP) in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). Seventy ACS patients scheduled to receive PCI were assigned to two groups. Around PCI, the 34 patients in the control group were treated with conventional therapy and the 36 in the DHI group treated with conventional therapy combined with DHI treatment given from the day of PCI to the 14th day after operation at the dose of 40 mL per day by dissolving in 250 mL of 5% glucose for venous dripping. Plasma levels of ET-1, sP-sel and hs-CRP were detected using ELISA at various time points: before PCI (T0), after PCI (T1), 24 h (T2) and 2 weeks (T3) after PCI. The outcomes were compared between the two groups, and compared with those obtained from 20 healthy persons set as the normal control. All the three indices in the two patients' group at T0, T1 and T2 were higher than those in the normal control respectively (P 0.05). Comparisons between the two patients' group showed that the indices were not different at TO, T1 and T2, but at T3, all were lower in the DHI group than in the control group (P sel and hs-CRP in ACS patients after PCI, suggesting that DHI has certain effects in protecting the endothelial function, inhibiting platelet activation and suppressing inflammatory reaction.

    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 consecutivepatients 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 dayCRP 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 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.

    ZFAS1 is one of cardiac-specific or cardiac-related lncRNAs. This study was to explore the functional involvement of ZFAS1 and its regulatory role in AMI. In this study, the models of AMI rat and myocardial cell cultured under hypoxia were made. The expression of ZFAS1 and miR-150 of myocardial infarction tissue or cardiac myocytes was determined by quantitative real time PCR. The regulatory role of ZFAS1 on miR-150 was examined by RNA pull down assay. The effect of miR-150 or ZFAS1 expression on cell viability was analyzed by MTT assay. The relative expression of ZFAS1 in the myocardium infracted zone and border zone was significantly upregulated at 1-48 h of AMI rats, but it downregulated at 1 week and 2 weeks; miR-150 was significantly downregulated at AMI-1-48 h and upregulated at 1 and 2 weeks after model establishment. The result of RNA pull down assay indicated that ZFAS1 could interact directly with miR-150. C-reactive protein (CRP) was regulated by ZFAS1/miR-150 axis and negatively targeted by miR-150. Hypoxia caused the decrease of cell viability and the upregulation of CRP at mRNA and protein levels; whereas this upregulation could be attenuated by miR-150 mimic or si-ZFAS1 in H9C2 cells and cardiomyocytes. Knockdown of ZFAS1 or miR-150 overexpression effectively relieved AMI-induced myocardial infarction in AMI-1 week rats. The ZFAS1/miR-150 axis was involved in the molecular mechanism of AMI induced cardiomyocytes apoptosis via regulating CRP. J. Cell.

    Recent findings suggest that maternal smoking during pregnancy may play a role in the development of metabolic alterations in offspring during childhood. However, whether such exposure increases the risk of developing similar metabolic alterations during adulthood is uncertain. We evaluated the association of in utero exposure to maternal tobacco smoke with plasma lipids, apolipoprotein B (apoB), and C-reactive protein (CRP) in adulthood. The study was based on a subsample of the Norwegian Mother and Child Cohort Study (MoBa) and included 479 pregnant women with plasma lipids, apoB, and CRP measurements. Information on in utero exposure to tobacco smoke, personal smoking, and other factors were obtained from the women by a self-completed questionnaire at enrollment, at approximately 17 weeks of gestation. Women exposed to tobacco smoke in utero had higher triglycerides [10.7% higher; 95% confidence interval (CI): 3.9, 17.9] and lower high-density lipoprotein cholesterol (HDL) (-1.9 mg/dL; 95% CI: -4.3, 0.5) compared with unexposed women, after adjusting for age, physical activity, education, personal smoking, and current body mass index (BMI). Exposed women were also more likely to have triglycerides ≥ 200 mg/dL [adjusted odds ratio (aOR) = 2.5; 95% CI: 1.3, 5.1] and HDL < 50 mg/dL (aOR = 2.3; 95% CI: 1.1, 5.0). Low-density lipoprotein cholesterol, total cholesterol, and apoB were not associated with the exposure. CRP was increased among exposed women; however, after adjustment for BMI, the association was completely attenuated. In this population, in utero exposure to tobacco smoke was associated with high triglycerides and low HDL in adulthood, 18-44 years after exposure.

    Purpose: A high-performance head-only magnetic resonance imaging gradient system with an acquisition volume of 26 cm employing an asymmetric design for the transverse coils has been developed. It is able to reach a magnitude of 85 mT/m at a slew rate of 700 T/m/s, but operated at 80 mT/m and 500 T/m/s for this test. A challenge resulting from this asymmetric design is that the gradient nonlinearly exhibits both odd- and even-ordered terms, and as the full imaging field of view is often used, the nonlinearity is pronounced. The purpose of this work is to show the system can produce clinically useful images after an on-site gradient nonlinearity calibration and correction, and show that acoustic noise levels fall within non-significant risk (NSR) limits for standard clinical pulse sequences. Methods: The head-only gradient system was inserted into a standard 3T wide-bore scanner without acoustic damping. The ACR phantom was scanned in an 8-channel receive-only head coil and the standard American College of Radiology (ACR) MRI quality control (QC) test was performed. Acoustic noise levels were measured for several standard pulse sequences. Results: Images acquired with the head-only gradient system passed all ACR MR image quality tests; Both even and odd-order gradient distortion correction terms were required for the asymmetric gradients to pass. Acoustic noise measurements were within FDA NSR guidelines of 99 dBA (with assumed 20 dBA hearing protection) A-weighted and 140 dB for peak for all but one sequence. Note the gradient system was installed without any shroud or acoustic batting. We expect final system integration to greatly reduce noise experienced by the patient. Conclusion: A high-performance head-only asymmetric gradient system operating at 80 mT/m and 500 T/m/s conforms to FDA acoustic noise limits in all but one case, and passes all the ACR MR image quality control tests.

    Full Text Available Este trabajo sitúa el problema de la guerra del Acre en un contexto multilateral, reconociendo la vigencia del equilibrio de poder como parte del razonamiento de la conducción de las políticas exteriores en juego. Se aplica el concepto de frontera de F. J. Turner, para explicar cómo las fronteras permeables pusieron a Brasil y Bolivia en confrontación, por la maniobra boliviana de configurar una concesión a inversionistas estadounidenses, británicos y franceses, que fue interpretada por Brasil como una maniobra imperialista de Estados Unidos. Entones Brasil se acercó a Chile, y afrontaron juntos los problemas del Acre y de Antofagasta, que derivaron en las redacciones de los tratados de Petrópolis (1903 y de Paz y Amistad (1904. El artículo postula que Bolivia procedió de esta forma para impedir el avance brasileño, peruano y paraguayo sobre sus fronteras, y que la búsqueda del paraguas estadounidense fue una idea que Bolivia gestó para compensar el desequilibrio de poder.This work considers the Acre War as part of a multilateral context where the equilibrium of power was important in the reasoning behind the establishment of foreign relations. It uses the frontier concept developed by F. J. Turner to explain why their open frontier put Brazil and Bolivia in confrontation. This happened because of the Bolivian strategy of granting land to investors from the United States, Great Britain and France, which was interpreted by Brazil as an imperialist action promoted by the United States. This explains why Brazil established a cióse relationship with Chile to confront together their problems in Acre and Antofagasta, which led to the drafting of the Petrópilis (1903 and Paz y Amistad (1904 treaties. The article argues that Bolivia proceeded this way to avoid a Brazilian, Peruvian or Paraguayan territorial advance, seeking the support of the United States to compénsate the imbalance of power.

    This research aimed to investigate the effects of a cognitive rehearsal program (CRP) on workplace bullying among nurses. A randomized controlled trial was performed. Participants were 40 nurses working in different university hospitals in B city, South Korea. The experimental group was provided with a 20-hour CRP comprising scenarios on bullying situations, standard communication, and role-playing. To evaluate effects of the CRP, we measured interpersonal relationships, workplace bullying, symptom experience, and turnover intention at preand post-intervention. Follow-up effect was measured in the experimental group only at 4 weeks after the intervention. After the intervention, there were significant differences in interpersonal relationships (F=6.21, p=.022) and turnover intention (F=5.55, p=.024) between experimental and wait-list groups. However, there was no significant difference in workplace bullying or symptom experience between the 2 groups. The beneficial effects on interpersonal relationships and turnover intention lasted at least up to 4 weeks after CRP. The CRP for workplace bullying improves interpersonal relationships and decreases turnover intention.

    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 fasting. Since most of these changes were reversible within 6 weeks, there seems no harm or benefit for obese adolescents to participate in Ramadan.

    Regular exposure to tobacco smoke at home causes airway inflammation and altered cytokine regulation; however, there is variation between individuals of different countries. To determine effects of passive smoking on plasma IL4, TNFá, and CRP in healthy male school-children in Khartoum. A total of 135 male school-pupils (69 passive smokers and 66 non-smokers) were selected randomly from three primary schools for boys in Khartoum. Information about smoking history was collected from each pupil and his parents using a questionnaire. Plasma CRP, IL4 and TNFá were measured using commercially available ELISA kits. Plasma IL4 and TNFá in the passive smokers (mean ± SEM) is at 2.92 ± 0.93 and 19.78 ± 4.67 pg/ml respectively; whereas in the non-smokers . It is at 0.45 ± 0.28 and 5.05 ± 1.54 pg/ml respectively. The difference between the two groups is statistically significant (p Passive smoking causes significant rise in plasma TNFá and IL4 with a dose dependent effect among school-pupils in Khartoum.

    Oxidative stress and inflammation have been reported to be higher in subjects with depression, but it is unclear whether this is due to inadequate dietary antioxidant intake or the pathophysiology of depression. The aim of this study was to assess the association between dietary and serum antioxidant status with depression scales in young male university students. This research was a case-control study carried out on 60 male university students (30 students diagnosed with depression and 30 matched healthy controls). Beck Depression Inventory-II was used to assess the major depressive disorder (MDD) scales. A semi-quantitative food frequency questionnaire and 2-day 24-h recalls were used for dietary assessment. Dietary and serum total antioxidant capacity (TAC) and high-sensitive C-reactive protein (hs-CRP) concentrations were also measured. MDD subjects consumed less fruits (P vitamin C (P = 0.005), beta carotene (P intake of dietary antioxidants. However, dietary TAC and serum hs-CRP levels were not significantly different between depressed and normal university male students. Intake of foods rich in antioxidants is encouraged in male students.

    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.

    The U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office manages two low-level Radioactive Waste Management Sites at the Nevada Test Site. The Area 5 RWMS uses engineered shallow-land burial cells to dispose of packaged waste. This report summarizes characterization and monitoring work pertinent to the 92-Acre Area in the southeast part of the Area 5 Radioactive Waste Management Sites. The decades of characterization and assessment work at the Area 5 RWMS indicate that the access controls, waste operation practices, site design, final cover design, site setting, and arid natural environment contribute to a containment system that meets regulatory requirements and performance objectives for the short- and long-term protection of the environment and public. The available characterization and Performance Assessment information is adequate to support design of the final cover and development of closure plans. No further characterization is warranted to demonstrate regulatory compliance. U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office is proceeding with the development of closure plans for the six closure units of the 92-Acre Area.

    Quality control and quality assurance (QC/QA) have been two of the most important issues in modern nuclear medicine (NM) imaging for both clinical practices and academic research. Whereas quantitative QC analysis software is common to modern positron emission tomography (PET) scanners, the QC of gamma cameras and/or single-photon-emission computed tomography (SPECT) scanners has not been sufficiently addressed. Although a thorough standard operating process (SOP) for mechanical and software maintenance may help the QC/QA of a gamma camera and SPECT-computed tomography (CT), no previous study has addressed a unified platform or process to decipher or analyze SPECT phantom images acquired from various scanners thus far. In addition, a few approaches have established cross-platform software to enable the technologists and physicists to assess the variety of SPECT scanners from different manufacturers. To resolve these issues, we have developed Interactive Data Language (IDL)-based in-house software for crossplatform (in terms of not only operating systems (OS) but also manufacturers) analyses of the QC data on an ACR SPECT phantom, which is essential for assessing and assuring the tomographical image quality of SPECT. We applied our devised software to our routine quarterly QC of ACR SPECT phantom images acquired from a number of platforms (OS/manufacturers). Based on our experience, we suggest that our devised software can offer a unified platform that allows images acquired from various types of scanners to be analyzed with great precision and accuracy.

  10. Bile salts and fatty acids induce the expression of Escherichia coli AcrAB multidrug efflux pump through their interaction with Rob regulatory protein.

    AcrAB of Escherichia coli, an archetype among bacterial multidrug efflux pumps, exports an extremely wide range of substrates including solvents, dyes, detergents and antimicrobial agents. Its expression is regulated by three XylS/AraC family regulators, MarA, SoxS and Rob. Although MarA and SoxS regulation works by the alteration of their own expression levels, it was not known how Rob, which is constitutively expressed, exerts its regulatory action. We show here that the induction of the AcrAB efflux pump by decanoate and the more lipophilic unconjugated bile salts is mediated by Rob, and that the low-molecular-weight inducers specifically bind to the C-terminal, non-DNA-binding domain of Rob. Induction of Rob is not needed for induction of AcrAB, and we suggest that the inducers act by producing conformational alterations in pre-existing Rob, as was suggested recently (Rosner, Dangi, Gronenborn and Martin, J Bacteriol 184: 1407-1416, 2002). Decanoate and unconjugated bile salts, which are present in the normal habitat of E. coli, were further shown to make the bacteria more resistant to lipophilic antibiotics, at least in part because of the induction of the AcrAB efflux pump. Thus, it is likely that E. coli is protecting itself by the Rob-mediated upregulation of AcrAB against the harmful effects of bile salts and fatty acids in the intestinal tract.

    Full Text Available Field studies in the western Amazon region (state of Acre, Brazil indicate that the 4-aminoquinolines, as well as the combined regimen with sulfadoxine-pyrimethamine, can no longer be recomended for the treatment and prophylaxis of P. falciparum infections in this region. Quinine remains an effective drug when used correctly. However, compliance problems arise due to the often occurring side-effects during a ten day regimen. Prospects of overcoming these constraints by combining a short course of quinine with other drugs are limited, because of the lack of suitable partner compounds. For this reason quinine/clindamycin appears to be a more practical therapy of P. falciparum malaria. In vitro data from this study suggest that mefloquine is another effective alternative for the treatment of falciparum malaria in this Amazon region.Estudos de campo na Amazonia ocidental (Estado do Acre, Brasil indicam que as 4-aminoquinolinas, assim como a sua combinação com sulfadoxina-pirimetamina não podem mais ser recomendadas para o tratamento e profilaxia das infecções pelo P. falciparum nesta região. A quinina permanece como droga efetiva quando usada corretamente. Entretanto, problemas podem surgir devido aos efeitos colaterais durante sua aplicação por período de 10 dias. Possibilidades de ultrapassar estes problemas combinando curto espaço de administração da quinina com outras drogas estão no momento limitadas devido à falta de um composto associado adequado. Por esta razão, a combinação quinina/clindamicina parece ser a terapêutica mais adequada para a malária pelo P. falciparum. Nossos estudos in vitro sugerem que a mefloquina é outra alternativa efetiva para o tratamento da malária falciparum nesta região da Amazônia.

    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.

    This study aimed to investigate the relationship of tirofiban, added to the treatment of acute ST-elevation myocardial infarction (STEMI) patients underwent primary percutaneous coronary intervention (PCI), with changes in the TIMI risk index (TRI) of TIMI flow, B-type natriuretic peptide (BNP) and high-sensitive C-reactive protein (hs-CRP) levels. This single-center, prospective observational cohort study included 102 consecutive patients who were admitted with the diagnosis of acute STEMI (70 male; 54.9±10.4 years). Primary PCI was applied to all cases with STEMI, who applied to our hospital in the first 6 hours due to chest pain complaints. Tirofiban was administered to one group (n=55) (male: 36; 54.1±11.3 years), while the other group was not given tirofiban (n=47) (male: 34; 55.9±9.1 years). The primary end-point was TIMI flow 2 or 3 for reperfusion after primary PCI. Chi-square test, paired t-test or Wilcoxon signed rank test, Spearman correlation analysis and Kaplan-Meier survival analysis were used for statistical analysis where appropriate. BNP level remained the same in the tirofiban group, whereas a significant increase was observed in the group that was not treated with tirofiban (105.9±126.8 versus 261.3±202.3 pg/ml pTIMI 2 flow in the tirofiban group, whereas a significant increase was detected in the post-treatment BNP (before 97.8±122.3 after 281.6±217.3 pg/ml, p=0.011) and hs-CRP (before 0.65±0.69; after 1.33±0.80 mg/L, p=0.028) values in the group not treated with tirofiban. In patients with TIMI 3 flow, BNP (tirofiban group before 146.5±114.2; after 184.4±139.4 pg/ml, p=0.011, non tirofiban group before 172.1±297.9; after 295.9±384.9 pg/ml, pTIMI 2 flow and anterior location MI could decrease the expected rise in BNP and CRP values.

    2008-12-01

    Full Text Available This study identifies literary testimony of the conflict over the nature of the Rosh ha-Shanah prayer in Nahmanides’ Sermon. Acre was in the 13th century home to rival Talmudic academies. In his Sermon for Rosh ha-Shanah, Ramban confronts the founding figures of the Tosafist community in the city. His ongoing controversy with contemporary sages can be read between the lines. Aside from brief segments, the majority of its Halakhic section is specifically aimed at opposing the Tosafists’ rulings, and the way in which material was chosen also highlights its polemical aim. In Ramban’s Novellae, he does not hesitate to argue with Tosafist and Andalusian-Geonic Halakhic rulings. Yet in the Sermon, he prefers citing reservations he had about the former. In the 13th century the intellectual momentum of the Tosafists came to a halt, simultaneous to the flourishing of Ramban’s study hall, and many Talmudic innovations were collected in the Novellae written by Ramban and his disciples. This transition forms an intellectual turning point in Talmud study. The confrontation among the academies in Acre may be viewed as a microcosm of this process.Este estudio analiza el conflicto en torno al carácter de la oración de Roš ha-Šaná en el Sermón de Na?mánides (Rambán. Acre albergaba en el siglo XIII academias talmúdicas rivales, y en su Sermón de Roš ha-Šaná, Rambán confronta a las figuras fundacionales de la congregación tosafista de esa ciudad. Su controversia con sabios coetáneos puede leerse entre líneas y, a excepción de alguna otra referencia a otros asuntos, la mayor parte de su exposición halájica, junto a la manera en la que el material expuesto ha sido elegido, se dedica a combatir las decisiones de aquéllos.

    Full Text Available The riparian rural cutover lands and backyards represent a sustainable alternative for the production of food and medicinal drugs to the traditional communities from the Amazon, especially with regard to products diversity and income generation. Considering the ecological and social functions of these spaces, this paper aims at analyzing the agrobiodiversity of these environments in the Boca Moa community, in the town of Cruzeiro do Sul, Acre, Brazil. Data collection was carried out through participative, formal, and inductive interviews following a semi-structured questionnaire with open questions, besides in loco visits. The rural cutover lands present many species at the same area, and manioc is the main product cultivated. The backyards have spatial arrangements of food species, with emphasis on fruits and vegetables, besides medicinal plants. Thus, both the backyards and rural cutover lands participate in the subsistence and income of riparian families from this community.

Ergonomic approaches, such as proper reading room structure, lighting, temperature, noise, and equipment setup, can help decrease the frequency and severity of repetitive strain injuries and improve radiologist productivity. However, ergonomic approaches are complex, include all aspects of the radiology practice environment, and are best implemented along with proper training of the practicing radiologists. The ergonomic approaches considered most important by members of the ACR Commission on Human Resources are presented in this report, and this information may serve as an aid in departmental planning.

    Catharanthus roseus, a medicinal plant, is known to produce secondary metabolites, vincristine and vinblastine, which are terpenoid indole alkaloids. Previously we have reported that Eutypella spp - CrP14 isolated from stem cutting of this plant had shown significant antiproliferative activity when tested in vitro against HeLa cell line. The present study was conducted to identify the anticancer compound responsible for the anti-proliferative activity of the fungal extract and to evaluate its in vitro anticancer and apoptotic effects. The anti-proliferative activity of the fungal anticancer compound, vincristine was analyzed by MTT assay against different cancer cell lines. We examined its efficacy of apoptotic induction on A431 cells. The parameters examined included cell cycle distribution, loss of mitochondrial membrane potential (MMP), DNA fragmentation and reactive oxygen species (ROS) generation. The presence of vincristine in fungal culture filtrate was confirmed through chromatographic and spectroscopic analyses, and the amount was estimated to be 53 ± 5.0 μg/l. The partially purified fungal vincristine had strong cytotoxic activity towards human squamous carcinoma cells - A431 in the MTT assay. Furthermore, we showed that the fungal vincristine was capable of inducing apoptosis in A431 cells through generation of reactive oxygen species and activation of the intrinsic pathway leading to loss of MMP. We have demonstrated for the first time that the vincristine from Eutypella spp - CrP14 is an efficient inducer of apoptosis in A431 cells, meriting its further evaluation in vivo.

    Background The present clinical trial study was designed to assess the effect of topical application of melatonin on serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and C-reactive protein (CRP) in patients with diabetes and periodontal disease in comparison with healthy controls. Material and Methods Serum levels of TNF-α and IL-6 were measured by enzyme-linked immunosorbent assay and CRP by nephelometry by using the proper commercial kits in 30 patients with diabetes and periodontal disease, and also in a control group of 30 healthy subjects. Periodontograms were performed using the Florida Probe®. Patients with diabetes were treated with a topical application of melatonin (1% orabase cream formula) once daily for 20 days. Healthy subjects were treated with a placebo orabase cream. Results Patients with diabetes and periodontal disease had significantly higher mean levels of serum TNF-α, IL-6 and CRP than healthy subjects (P < 0.001). Following topical melatonin application, there was a statistically significant decrease in the gingival index and pocket depth (P < 0.001) as well as a significant decrease in IL-6 and CRP serum levels (P < 0.001). Local melatonin application in patients with diabetes and periodontal disease resulted in a significant decrease in CRP and IL-6 serum levels as well as an improvement in the gingival index and pocket depth. Patients with periodontal disease had significantly higher serum CRP, IL-6 and TNF-α values by comparison with healthy subjects. Conclusions We conclude that melatonin can modulate the inflammatory action of these molecules in periodontal patients. Key words:Melatonin, periodontal disease, diabetes mellitus, interleukin-6, tumor necrosis factor-alpha, C-reactive protein, inflammatory markers. PMID:26644840

    Full Text Available Objective: Addiction to narcotic drugs is associated with cardiovascular diseases; and increased levels of biomarkers, such as C-reactive protein and fibrinogen are independently correlated with the risk of cardiovascular diseases. Therefore, this study aimed to investigate the effects of 8 weeks of resistance training on C-reactive protein and fibrinogen levels in drug addicted men. Method: In this quasi-experimental study with pretest-posttest, the number of 30 male addicts was randomly divided into resistance training group (n = 15 and non-sports control group (n = 15. Then, resistance training was conducted within two months, four days a week, and 50 to 60 minutes a day. The serum levels of C-reactive protein, fibrinogen, body compositions, and metabolic parameters were evaluated before and after the training period. Results: After the passage of 8 weeks of resistance training, skeletal muscle strength significantly increased (P < .05. At the same time, levels of C-reactive protein and fibrinogen significantly decreased in response to resistance training (P < .05. Conclusion: Short-term resistance training program improves muscle mass and strength in the male addicts after drug abstinence and this improvement is associated with reduced levels of C-reactive protein and fibrinogen.

    The resistance-nodulation-division (RND) family efflux pumps are important in the antibiotic resistance of Gram-negative bacteria. However, although a number of bacterial RND efflux pump inhibitors have been developed, there has been no clinically available RND efflux pump inhibitor to date. A set of BSN-coded 2-substituted benzothiazoles were tested alone and in combinations with ciprofloxacin (CIP) against the AcrAB-TolC overexpressor Escherichia coli AG102 clinical strain. The results indicated that the BSN compounds did not show intrinsic antimicrobial activity when tested alone. However, when used in combinations with CIP, a reversal in the antibacterial activity of CIP with up to 10-fold better MIC values was observed. In order to describe the binding site features of these BSN compounds with AcrB, docking studies were performed using the CDocker method. The performed docking poses and the calculated binding energy scores revealed that the tested compounds BSN-006, BSN-023, and BSN-004 showed significant binding interactions with the phenylalanine-rich region in the distal binding site of the AcrB binding monomer. Moreover, the tested compounds BSN-006 and BSN-023 possessed stronger binding energies than CIP, verifying that BSN compounds are acting as the putative substrates of AcrB.

    Vaccination of laying hens has been successfully used to reduce egg contamination by Salmonella Enteritidis, decreasing human salmonellosis cases worldwide. Currently used vaccines for layers are either inactivated vaccines or live attenuated strains produced by mutagenesis. Targeted gene deletion mutants hold promise for future vaccines, because specific bacterial functions can be removed that may improve safety and allow differentiation from field strains. In this study, the efficacy of Salmonella Enteritidis ΔtolC and ΔacrABacrEFmdtABC strains in laying hens as live vaccines was evaluated. The mutants are deficient in either the membrane channel TolC (ΔtolC) or the multi-drug efflux systems acrAB, acrEF and mdtABC (ΔacrABacrEFmdtABC). These strains have a decreased ability for gut and tissue colonization and are unable to survive in egg white, the latter preventing transmission of the vaccine strains to humans. Two groups of 30 laying hens were orally inoculated at day 1, 6 weeks and 16 weeks of age with 10(8) cfu of either vaccine strain, while a third group was left unvaccinated. At 24 weeks of age, the birds were intravenously challenged with 5 × 10(7) cfu Salmonella Enteritidis PT4 S1400/94. The vaccine strains were not shed or detected in the gut, internal organs or eggs, 2 weeks after the third vaccination. The strains significantly protected against gut and internal organ colonization, and completely prevented egg contamination by Salmonella Enteritidis under the conditions of this study. This indicates that Salmonella Enteritidis ΔtolC and ΔacrABacrEFmdtABC strains might be valuable strains for vaccination of layers against Salmonella Enteritidis.

    This Pinellas County, Florida, Site Environmental Restoration Project Semiannual Progress Report for the 4.5 Acre Site describes environmental restoration activities for the 4.5 Acre Site located in Pinellas County, Largo, Florida (Figure 1). The former U.S. Department of Energy (DOE) Pinellas Plant facility consisted of the 4.5 Acre Site and what is now the STAR Center (Young - Rainey Science, Technology, and Research Center). Both the 4.5 Acre Site and the STAR Center are part of the overall Pinellas County, Florida, Site (Figure 2). The 4.5 Acre Site is located immediately northwest of the STAR Center, in the northeast quarter of Section 13, Township 30 South, Range 15 East. DOE owned this parcel from 1957 to 1972, at which time it was sold to a private landowner. During the period of DOE ownership, the property was used for the disposal of drums of waste resins and solvents. As a result of this practice, the surficial aquifer was impacted by volatile organic compounds (VOCs)—trichloroethene (TCE), cis-1,2-dichloroethene (cDCE), trans-1,2-dichloroethene (tDCE), vinyl chloride (VC), and benzene. Detailed background information for the site is contained in the Long-Term Surveillance and Maintenance Plan for the Pinellas Site (DOE 2016). That document and other site-related documents can be accessed at this website: http://www.lm.doe.gov/Pinellas/Sites.aspx. Recent remediation activities consist of the injection of emulsified soybean oil and the microorganism Dehalococcoides mccartyi (formerly known as Dehalococcoides ethenogenes) into the subsurface in February 2010 and again in July 2013 to enhance contaminant biodegradation (hereafter described as bioinjection). Monitoring the performance of these actions, in the form of monitoring well sampling, is ongoing.

    Drug efflux pumps confer multidrug resistance to dangerous pathogens which makes these pumps important drug targets. We have synthesised a novel series of compounds based on a 2-naphthamide pharmacore aimed at inhibiting the efflux pumps from Gram-negative bacteria. The archeatypical transporter AcrB from Escherichia coli was used as model efflux pump as AcrB is widely conserved throughout Gram-negative organisms. The compounds were tested for their antibacterial action, ability to potentiate the action of antibiotics and for their ability to inhibit Nile Red efflux by AcrB. None of the compounds were antimicrobial against E. coli wild type cells. Most of the compounds were able to inhibit Nile Red efflux indicating that they are substrates of the AcrB efflux pump. Three compounds were able to synergise with antibiotics and reverse resistance in the resistant phenotype. Compound A3, 4-(isopentyloxy)-2-naphthamide, reduced the MICs of erythromycin and chloramphenicol to the MIC levels of the drug sensitive strain that lacks an efflux pump. A3 had no effect on the MIC of the non-substrate rifampicin indicating that this compound acts specifically through the AcrB efflux pump. A3 also does not act through non-specific mechanisms such as outer membrane or inner membrane permeabilisation and is not cytotoxic against mammalian cell lines. Therefore, we have designed and synthesised a novel chemical compound with great potential to further optimisation as inhibitor of drug efflux pumps. Copyright © 2017 Elsevier Ltd.

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
