    There has been an increase in the number of individuals seeking testosterone (T) replacement treatment (TRT) due to a decrease in their blood T levels. Prostate cancer (PCa) is also an important issue in the same age group. However, we, urologists, are anxious about PCa development after T treatment. This is because it has been assumed that T may cause PCa or exacerbate insidious PCa which is already present. In this paper, recent developments regarding the relationship between serum levels o...

  3. Mixed and Low-Level Treatment Facility Project

    Energy Technology Data Exchange (ETDEWEB)

    1992-04-01

    This appendix contains the mixed and low-level waste engineering design files (EDFS) documenting each low-level and mixed waste stream investigated during preengineering studies for Mixed and Low-Level Waste Treatment Facility Project. The EDFs provide background information on mixed and low-level waste generated at the Idaho National Engineering Laboratory. They identify, characterize, and provide treatment strategies for the waste streams. Mixed waste is waste containing both radioactive and hazardous components as defined by the Atomic Energy Act and the Resource Conservation and Recovery Act, respectively. Low-level waste is waste that contains radioactivity and is not classified as high-level waste, transuranic waste, spent nuclear fuel, or 11e(2) byproduct material as defined by DOE 5820.2A. Test specimens of fissionable material irradiated for research and development only, and not for the production of power or plutonium, may be classified as low-level waste, provided the concentration of transuranic is less than 100 nCi/g. This appendix is a tool that clarifies presentation format for the EDFS. The EDFs contain waste stream characterization data and potential treatment strategies that will facilitate system tradeoff studies and conceptual design development. A total of 43 mixed waste and 55 low-level waste EDFs are provided.

    Periodontitis induces excessive production of reactive oxygen species in periodontal lesions. This may impair circulating pro-oxidant/anti-oxidant balance and induce the oxidation of low-density lipoprotein (LDL) in blood. The purpose of this study was to monitor circulating oxidized LDL and oxidative stress in subjects with chronic periodontitis following non-surgical periodontal treatment. Plasma levels of oxidized LDL and oxidative stress in 22 otherwise healthy non-smokers with chronic periodontitis (mean age 44.0 years) were measured at baseline and at 1 and 2 months after non-surgical periodontal treatment. At baseline, chronic periodontitis patients had higher plasma levels of oxidized LDL and oxidative stress than healthy subjects (p surgical periodontal treatment were effective in decreasing oxLDL, which was positively associated with a reduction in circulating oxidative stress.

    Mixed treatment comparisons (MTC) extend the traditional pair-wise meta-analytic framework to synthesize information on more than two interventions. Although most MTCs use aggregate data (AD), a proportion of the evidence base might be available at the individual level (IPD). We develop a series of novel Bayesian statistical MTC models to allow for the simultaneous synthesis of IPD and AD, potentially incorporating study and individual level covariates. The effectiveness of different interventions to increase the provision of functioning smoke alarms in households with children was used as a motivating dataset. This included 20 studies (11 AD and 9 IPD), including 11 500 participants. Incorporating the IPD into the network allowed the inclusion of information on subject level covariates, which produced markedly more accurate treatment-covariate interaction estimates than an analysis solely on the AD from all studies. Including evidence at the IPD level in the MTC is desirable when exploring participant level covariates; even when IPD is available only for a fraction of the studies. Such modelling may not only reduce inconsistencies within networks of trials but also assist the estimation of intervention subgroup effects to guide more individualised treatment decisions.

    The technology information provided in this report is only the first step toward the identification and selection of process systems that may be recommended for a proposed mixed and low-level waste treatment facility. More specific information on each technology will be required to conduct the system and equipment tradeoff studies that will follow these preengineering studies. For example, capacity, maintainability, reliability, cost, applicability to specific waste streams, and technology availability must be further defined. This report does not currently contain all needed information; however, all major technologies considered to be potentially applicable to the treatment of mixed and low-level waste are identified and described herein. Future reports will seek to improve the depth of information on technologies.

    Background: Low Level Laser Therapy (LLLT) is used in the treatment of tendon injuries. However, the clinical effectiveness of this modality remains controversial with limited agreement on the most efficacious dosage and parameter choices. Purpose: To assess the clinical effectiveness of LLLT in the treatment of tendinopathy and the validity of current dosage recommendations for treatment. Method: Medical databases were searched from inception to 1st August 2008. Controlled clinical trials evaluating LLLT as a primary intervention for any tendinopathy were included in the review. Methodological quality was classified using the PEDro scale. Appropriateness of treatment parameters were assessed using established guidelines. Results: Twenty five trials met the inclusion criteria. There was conflicting findings from multiple trials: 12 showed positive effects and 13 were inconclusive or showed no effect. Dosages used in the 12 positive studies support the existence of an effective dosage window that closely resembled current guidelines. Where pooling of data was possible, LLLT showed a positive effect size; in high quality studies of lateral epicondylitis, participants' grip strength was 9.59 Kg higher than the control group; for participants with Achilles tendinopathy, the effect was 13.6 mm less pain on a 100 mm visual analogue scale. Conclusion: This study found conflicting evidence as to the effectiveness of LLLT in the treatment of tendinopathy. However, an effective dosage window emerged showing benefit in the treatment of tendinopathy. Strong evidence exists from the 12 positive studies that positive outcomes are associated with the use of current dosage recommendations for the treatment of tendinopathy.

    Isthmic spondylolisthesis, which is demonstrated in 4%-6% of the general population, is one of the most common types of spondylolisthesis. However, double-level isthmic spondylolisthesis is extremely rare. Only a few reports have examined the outcomes of surgical treatment of double-level spondylolisthesis. The authors present an unusual case of double-level isthmic spondylolisthesis of the lumbar spine. The patient had low-back pain for 20 years and did not respond to conservative treatment. Radiographs revealed bilateral pars defects at L-4 and L-5. Grade 2 isthmic spondylolisthesis was present, both at L4-5 and at L5-S1. The patient underwent decompression, reduction, and posterior lumbar interbody fusion with autogenous bone chips from posterior decompression. At follow-up after 12 months, the patient was free of pain, slippage was corrected, and fusion was achieved. Posterior lumbar interbody fusion with posterior instrumentation and reduction may yield good functional short-term results for double-level spondylolisthesis.

    Full Text Available The purpose of this study was to evaluate the effect of medium-level laser therapy in chronic tinnitus treatment. In a prospective double-blind placebo-controlled trial, either active laser (450 mW, 830 nm combined Ga-Al-As diode laser or placebo irradiation was applied through the external acoustic meatus of the affected ear towards the cochlea. Fourty-eight patients with chronic tinnitus were studied. The main outcome was measured using the Goebel tinnitus questionnaire, visual analogue scales measuring the perceived loudness of tinnitus, the annoyance associated with tinnitus, and the degree of attention paid to tinnitus as well as psycho-acoustical matches of tinnitus pitch and loudness. The results did show only very moderate temporary improvement of tinnitus. Moreover, no statistically relevant differences between laser and placebo group could be found. We conclude that medium-level laser therapy cannot be regarded as an effective treatment of chronic tinnitus in our therapy regime considering the limited number of patients included in our study.

  15. KINETICS OF BIOLOGICAL TREATMENT OF LOW LEVEL PESTICIDE WASTEWATER

    Full Text Available Pesticides are chemical substances intended to protect food crops and livestock from pests in order to pro-mote agricultural productivity and protect public health. Contamination of soil, air and water and threat to human and animal health are the major constraints in the use of pesticides. Treatment of pesticide contaminated water is, therefore, paramount. Biological treatment provides the most economical option when compared to other treatment methods. The aim of the study was to develop a safe and effective in the farm biological treatment for low level agricultural pesticide wastewater. The degradation of the fungicide captan was evaluated under batch and continuous modes of operation with a retention time of 15 days. The initial cell number (30.1ח106 cells/mL in the soil water mixture first declined with time during the 24 h reaching 15.6ח106 and 11.1ח106 cells/mL in the batch and continuous bioreactors, respectively. This was due to the inhibitory effect of pesticide on some of the soil microbial species that had less tolerance to captan at the initial concentration of 144 mg L-1. Then, the microbial population started growing, reaching its maximum after 5 and 12 days from the start in the batch and continuous bioreactors, respectively. The lag period and the specific growth rate for the batch bioreactor were 22 h and 0.096 h-1, respectively. A captan degradation efficiency of 89.6% was achieved after 10 days in the continuous bioreactor compared to a degradation efficiency of 100% after 5 d in the batch bioreactor. This study showed that the effluent from the continuous bioreactor has a captan concentration of 12 mg L-1 which is not acceptable for livestock water according to Health Canada Guidelines. A half life of 52 h is observed in the batch bioreactor.

    OBJECTIVES: There is a growing literature indicating that organizational and individual worker-level factors affect decisions about whether or not empirically supported treatments (ESTs) are adopted within health care agencies. The purpose of this pilot study is to further investigate and measure worker's attitudes within a community organization. METHOD: A small organization participated in the study due to their diversity in services offered. Of the 92 workers eligible for participation in the study, 66 (72%) completed the Evidence-Based Practice Attitude scale survey. RESULTS: Multivariate analyses revealed that female workers scored higher on both Openness and total score; workers with nursing, education, or psychology majors scored lower than workers with other (excluding social work) majors on both Divergence and total score; and that older workers scored higher on Divergence. CONCLUSION: Although small, this study identifies individual characteristics that are most likely to fit the profile of an EST adopter.

    Full Text Available In water treatment processes, aluminum salts are widely used as coagulation chemical. High dose of aluminum has been proved to be at least a minor health risk and some evidence points out that aluminum could increase the risk of Alzheimer's disease thus it is important to minimize the amount of residual aluminum in drinking water and water used at food industry. In this study, the data of a water treatment plant (WTP was analyzed and the residual aluminum in drinking water was predicted using Multiple Linear Regression (MLR and Artificial Neural Network (ANN models. The purpose was to find out which variables affect the amount of residual aluminum and create simple and reliable prediction models which can be used in an early warning system (EWS. Accuracy of ANN and MLR models were compared. The new nonlinear scaling method based on generalized norms and skewness was used to scale all measurement variables to range [−2...+2] before data-analysis and modeling. The effect of data pre-processing was studied by comparing prediction results to ones achieved in an earlier study. Results showed that it is possible to predict the baseline level of residual aluminum in drinking water with a simple model. Variables that affected the most the amount of residual aluminum were among others: raw water temperature, raw water KMnO4 and PAC / KMnO4-ratio. The accuracies of MLR and ANN models were found to be almost equal. Study also showed that data pre-processing affects to the final prediction result.

  20. Inversion of levelling data: how important is error treatment?

    Amoruso, A.; Crescentini, L.

    2007-12-01

    Even if proper treatment of error statistics is potentially essential for the reliability of experimental data inversion, a critical evaluation of its effects on levelling data inversion is still lacking. In this paper, we consider the complete covariance matrix for levelling measurements, obtained by combining the covariance matrix due to measurement errors and the covariance matrix due to non-measurement errors, under the simple hypothesis of uncorrelated non-measurement errors on bench mark vertical displacements. The complete covariance matrix is reduced to diagonal form by means of a rotation matrix; the same rotation transforms the data to independent form. The eigenvalues of the complete covariance matrix give the uncertainties of the transformed independent data. This procedure can be used also with non-normal distributions of errors, in which case misfit functions other than χ2 (e.g. the mean absolute deviation) are minimized. Here we focus on two test cases (the 1989 Loma Prieta earthquake and the 1908 Messina earthquake) inverting both real data and synthetics. The inversion of synthetic data sets does not evidence any systematic dependence of retrieved parameter values on the covariance matrix. Most retrieved fault parameter values are close to what used in the forward model, whatever covariance matrix is used. As a consequence, large discrepancies among results obtained using covariance matrices including different combinations of measurement and non-measurement errors when inverting measured and synthetic data sets would possibly indicate the need for further investigations. While measurement errors can be a priori evaluated, it is difficult to estimate non-measurement errors. Our synthetic tests using a uniform-slip rectangular fault in a homogeneous elastic half-space show that, if measurement errors have been correctly evaluated, average non-measurement errors can be estimated by choosing their weight inside the covariance matrix so that the ratio

    The effect in mice of 8 subcutaneous injections of 20 microgram of L-thyroxine at 12 hr-intervals on the carnitine concentration in the heart and skeletal muscle tissue was studied. In skeletal muscle tissue, the thyroxine treatment resulted in a depressed carnitine concentration. The mean values were 1.59 +/- 0.034 (S.E.M.) and 2.03 +/- 0.045 mumol/g noncollagen protein and 1.11 +/- 0.035 and 1.45 +/- 0.037 mumol/g dry weight for the thyroxine treated and the control animals, respectively. Thyroxine produced myocardial hypertrophy. The thyroxine treated animals had lower cardiac values when dry weight was used as reference base 4.17 +/- 0.10 mumol/g dry weight than the control group, 4.69 +/- 0.18 mumol/g dry weight. No statistically significant difference was found between the two groups when the cardiac carnitine concentration was expressed per g noncollagen protein or as carnitine in the entire hearts. Thus, thyroxine has been showed to influence the metabolism of carnitine in mice.

    Research studies have identified addiction treatment staff who have higher levels of education as having more positive attitudes about evidence-based treatment practices, science-based training, and the usefulness of evidence-based practices. This study examined associations between addiction treatment staff level of education and their perceptions of 3 measures of organizational change: organizational stress, training resources and staffing resources in their treatment unit. The sample included 588 clinical staff from community-based substance abuse treatment organizations who received Substance Abuse and Mental Health Services Administration (SAMHSA) funding (2003-2008) to implement evidence-based practices (EBPs). Bivariate analysis and regression modeling methods examined the relationship between staff education level (no high school education, high school education, some college, associate's degree, bachelor's degree, master's degree, doctoral degree, and other type of degree such as medical assistant, registered nurse [RN], or postdoctoral) and attitudes about organizational climate (stress), training resources, and staffing resources while controlling for staff and treatment unit characteristics. Multivariable models identified staff with lower levels of education as having significantly more positive attitudes about their unit's organizational capacity. These results contradict findings that addiction treatment staff with higher levels of education work in units with greater levels of organizational readiness for change. It cannot be inferred that higher levels of education among treatment staff is necessarily associated with high levels of organizational readiness for change.

    Full Text Available Introduction: Pre-treatment HIV drug resistance (PDR is an increasing problem in sub-Saharan Africa. Children are an especially vulnerable population to develop PDR given that paediatric second-line treatment options are limited. Although monitoring of PDR is important, data on the paediatric prevalence in sub-Saharan Africa and its consequences for treatment outcomes are scarce. We designed a prospective paediatric cohort study to document the prevalence of PDR and its effect on subsequent treatment failure in Nigeria, the country with the second highest number of HIV-infected children in the world. Methods: HIV-1-infected children ≤12 years, who had not been exposed to drugs for the prevention of mother-to-child transmission (PMTCT, were enrolled between 2012 and 2013, and followed up for 24 months in Lagos, Nigeria. Pre-antiretroviral treatment (ART population-based pol genotypic testing and six-monthly viral load (VL testing were performed. Logistic regression analysis was used to assess the effect of PDR (World Health Organization (WHO list for transmitted drug resistance on subsequent treatment failure (two consecutive VL measurements >1000 cps/ml or death. Results: Of the total 82 PMTCT-naïve children, 13 (15.9% had PDR. All 13 children harboured non-nucleoside reverse transcriptase inhibitor (NNRTI mutations, of whom seven also had nucleoside reverse transcriptase inhibitor resistance. After 24 months, 33% had experienced treatment failure. Treatment failure was associated with PDR and a higher log VL before treatment initiation (adjusted odds ratio (aOR 7.53 (95%CI 1.61–35.15 and 2.85 (95%CI 1.04–7.78, respectively. Discussion: PDR was present in one out of six Nigerian children. These high numbers corroborate with recent findings in other African countries. The presence of PDR was relevant as it was the strongest predictor of first-line treatment failure. Conclusions: Our findings stress the importance of implementing fully

    The Mixed and Low-Level Waste Treatment Facility (MLLWTF) project was established in 1991 by the US Department of Energy Idaho Field Office to provide treatment capabilities for Idaho National Engineering Laboratory (INEL) low-level mixed waste and low-level waste. This report identifies and evaluates the alternatives for treating that waste. Twelve treatment alternatives, ranging from ``no-action`` to constructing and operating the MLLWTF, are identified and evaluated. Evaluations include facility performance, environmental, safety, institutional, schedule, and rough order-of-magnitude cost comparisons. The performance of each alternative is evaluated against lists of ``musts`` and ``wants.`` Also included is a discussion of other key considerations for decision making. Analysis of results indicated further study is necessary to obtain the best estimate of future waste volumes and characteristics from the expanded INEL Decontamination and Decommissioning Program. It is also recommended that conceptual design begin as scheduled on the MLLWTF, maximum treatment alternative while re-evaluating the waste volume projections.

    The aim was to evaluate the association between plasma tissue inhibitor of metalloproteinase-1 (TIMP-1) and serum carcinoembryonic antigen (CEA) levels and outcome in patients with metastatic colorectal cancer (mCRC) receiving XELOX (combination chemotherapy with capecitabine and oxaliplatin) as first-line treatment. One hundred and twenty patients were included. Blood samples were collected before treatment and 3 weeks later before the next treatment cycle. Plasma TIMP-1 and serum CEA levels were correlated to treatment outcome. No significant associations between baseline TIMP-1 or CEA levels and best response to treatment or progression-free survival (PFS) could be demonstrated. In contrast, high baseline plasma TIMP-1 levels were associated with poor overall survival (OS), P = 0.008, hazard ratio (HR) = 1.80 [95% confidence interval (CI): 1.17-2.78]. Furthermore, increase in TIMP-1 levels from baseline to immediately before the second cycle of chemotherapy had a significant negative effect on survival (P = 0.03, HR = 1.30, 95% CI: 1.02-1.65) while a decrease in TIMP-1 was significantly associated with a higher objective response rate (P = 0.03). Both high baseline and subsequent increase in TIMP-1 levels were associated with shorter OS in patients with mCRC receiving XELOX as first-line treatment, whereas baseline TIMP-1 levels were not associated with response or PFS following XELOX treatment.

    Serum levels of inflammatory cytokines, for example, tumor necrosis factor alpha (TNFα), interleukin-6 (IL-6), and IL-1 beta (IL-1β), are elevated in subjects with major depressive disorder (MDD). The reason why this occurs is unclear. Elevated levels of inflammatory cytokines could be a result of brain dysfunction in MDD. It is also possible that inflammatory cytokines contribute to depressive symptoms in MDD. If the first assumption is correct, one would expect levels to normalize with resolution of the depressive episode after treatment. Several studies have measured changes in cytokine levels during antidepressant treatment; however, the results vary. The purpose of this study was to pool all available data on changes in serum levels of TNFα, IL-6, and IL-1β during antidepressant treatment to determine whether these levels change. Studies were included if they used an approved pharmacological treatment for depression, patients had a diagnosis of MDD, and serum levels of TNFα, IL-6, and/or IL-1β were measured before and after treatment. Twenty-two studies fulfilled these criteria. Meta-analysis of these studies showed that, overall, while pharmacological antidepressant treatment reduced depressive symptoms, it did not reduce serum levels of TNFα. On the other hand, antidepressant treatment did reduce levels of IL-1β and possibly those of IL-6. Stratified subgroup analysis by class of antidepressant indicated that serotonin reuptake inhibitors may reduce levels of IL-6 and TNFα. Other antidepressants, while efficacious for depressive symptoms, did not appear to reduce cytokine levels. These results argue against the notion that resolution of a depressive episode is associated with normalization of levels of circulating inflammatory cytokines; however, the results are consistent with the possibility that inflammatory cytokines contribute to depressive symptoms and that antidepressants block the effects of inflammatory cytokines on the brain.

    Background. Transferrin is a negative acute phase protein, which decreases during inflammation and infection. The aim of the present investigation was to evaluate changes in the transferrin serum levels subsequent to non-surgical treatment of chronic periodontal disease. Methods. Twenty patients with chronic periodontitis and 20 systemically healthy subjects without periodontal disease, who had referred to Tabriz Faculty of Dentistry, were selected. Transferrin serum levels and clinical periodontal parameters (pocket depth, clinical attachment level, gingival index, bleeding index and plaque index) were measured at baseline and 3 months after non-surgical periodontal treatment. Data were analyzed with descriptive statistical methods (means ± standard deviations). Independent samples t-test was used to compare transferrin serum levels and clinical variables between the test and control groups. Paired samples t-test was used in the test group for comparisons before and after treatment. Statistical significance was set at P < 0.05. Results. The mean transferrin serum level in patients with chronic periodontitis (213.1 ± 9.2 mg/dL) was significantly less than that in periodontally healthy subjects (307.8 ± 11.7 mg/dL). Three months after periodontal treatment, the transferrin serum level increased significantly (298.3 ± 7.6 mg/dL) and approached the levels in periodontally healthy subjects (P < 0.05). Conclusion. The decrease and increase in transferrin serum levels with periodontal disease and periodontal treatment, respectively, indicated an inverse relationship between transferrin serum levels and chronic periodontitis.

    Neurotransmitter amino acid levels were measured in select brain regions of rats and mice after chronic treatment with sublethal doses of sodium hydrosulfide (NaHS). Brainstem aspartate, glutamate, glutamine, taurine and GABA levels increased in chronically but not acutely saline-treated rats. These increases may have been due to stress from frequent handling, and were prevented by chronic NaHS treatment (7.5 mg/kg ip every 8 hr for 3 consecutive days). In contrast, aspartate, glutamate and glutamine increased in female but not in male ICR mouse brainstems after once daily treatment with 7.0 mg/kg NaHS for 5 consecutive days. These effects of NaHS may indicate chronic low level H2S neurotoxicity. Differences between chronic and acute treatments, female and male responses, and treatment paradigms may complicate interpretations of such toxicity studies.

    We aimed to assess the relationship between cytokine levels and the severity of the manic period in medication free patients. 30 Medication free patients and 28 healthy subjects (HS) were recruited. Plasma levels of pro-inflammatory, anti-inflammatory, inflammatory cytokines, and hs-CRP levels were investigated upon hospital admission, after six weeks follow up in bipolar disease manic episode and the results were compared to HS. The severity of the manic episodes was assessed according to the Young mania rating scale. TNF-α, INF-γ, IL-6 and hs-CRP levels were significantly higher in patients with manic episode of bipolar I disorder before treatment than HS. After treatment the levels of TNF-α, INF-γ, IL-6 and hs-CRP were observed to be significantly decreased. There was no difference between the levels of anti-inflammatory cytokines in patients before or after treatment of bipolar disorder and HS. hs-CRP was observed to be the only parameter correlated with clinical response. The most significant outcome of this study is the correlation between clinical outcome and hs-CRP levels in treatment naive manic episode bipolar type I patients. hs-CRP is the most consistent indicator according to pro-inflammatory, inflammatory and anti-inflammatory cytokines, in predicting treatment outcomes.

    Background Glucocorticoid signaling exerts major roles in inflammation, metabolism and depression, which are three crucial factors accompanying or underlying coronary heart disease. Although accumulating evidence indicates the influence of glucocorticoids on the pathology and treatment of coronary heart disease, there is still a dearth of pharmaceutical mechanisms for this relationship. This study aimed to investigate the influence of drug treatment on glucocorticoid receptor levels in coronary heart disease.Methods Eighty hospitalized patients (average age (59.0 7.5) years, 46 male and 34 female) with coronary heart disease were categorized into four groups with 20 members in each according to one of the four drugs they were treated with. The four drugs were: nitrated derivative isosorbide dinitrate, the beta-adrenergic receptor blocker metoprolol, the calcium antagonist nifedipine, and the HMG-CoA reductase inhibitor lovastatin. Glucocorticoid receptor protein levels of peripheral blood lymphocytes were tested using immunoblotting analysis before and after one month of treatment. Results Immunoblotting analysis showed increased glucocorticoid receptor levels after treatment with metoprolol and nifedipine. There were no statistically significant changes of glucocorticoid receptor levels after treatment with isosorbide dinitrate or lovastatin, although there were trends of up-regulation of glucocorticoid receptor expression after both treatments.Conclusions Both the beta-blocker and the calcium blocker can increase glucocorticoid receptor levels after chronic administration. This effect suggests a mechanism for their anti-inflammatory and other therapeutic roles for coronary heart disease and comorbid disorders.

    Honey bee colony loss continues to be an issue and no factor has been singled out as to the cause. In this study, we sought to determine whether two beekeeper-applied pesticide products, tau-fluvalinate and Fumagilin-B®, and one agrochemical, chlorothalonil, impact the nutrient levels in honey bee workers in a natural colony environment. Treatments were performed in-hive and at three different periods (fall, spring, and summer) over the course of one year. Bees were sampled both at pre-treatment and two and four weeks post-treatment, weighed, and their protein and carbohydrate levels were determined using BCA and anthrone based biochemical assays, respectively. We report that, based on the pesticide concentrations tested, no significant negative impact of the pesticide products was observed on wet weight, protein levels, or carbohydrate levels of bees from treated colonies compared with bees from untreated control colonies.

    1990-01-01

    Milk yield and milk acetoacetate (M-acac) were measured weekly for the first 6 weeks of lactation in 5 herds with a ketosis problem. Ketosis treatments and the corresponding ketotest score, were also recorded. The treatment rate was highest 7-16 days after calving. Most of these early cases were associated with low ketone levels in milk, whereas the treatment rate for cows with high ketone levels was highest 17-31 days after calving. Nearly half of the treated cows were low-ketone animals. They were classified as ketosis cases in the cow health card records, although probably suffering from other post partum disturbances in many instances. About 40% of the cows with high ketone levels recovered spontaneously. Reduction in milk yield associated with peak M-acac levels was transient and moderate. It was concluded that health card statistics overestimates the severity of the ketosis problem in Norway.

    Full Text Available Abstract Background Despite of an increasing body of research the associations between vitamin B12 and folate levels and the treatment outcome in depressive disorders are still unsolved. We therefore conducted this naturalistic prospective follow-up study. Our aim was to determine whether there were any associations between the vitamin B12 and folate level and the six-month treatment outcome in patients with major depressive disorder. Because vitamin B12 and folate deficiency may result in changes in haematological indices, including mean corpuscular volume, red blood cell count and hematocrit, we also examined whether these indices were associated with the treatment outcome. Methods Haematological indices, erythrocyte folate and serum vitamin B12 levels were determined in 115 outpatients with DSM-III-R major depressive disorder at baseline and serum vitamin B12 level again on six-month follow-up. The 17-item Hamilton Depression Rating Scale was also compiled, respectively. In the statistical analysis we used chi-squared test, Pearson's correlation coefficient, the Student's t-test, analysis of variance (ANOVA, and univariate and multivariate linear regression analysis. Results Higher vitamin B12 levels significantly associated with a better outcome. The association between the folate level and treatment outcome was weak and probably not independent. No relationship was found between haematological indices and the six-month outcome. Conclusion The vitamin B12 level and the probability of recovery from major depression may be positively associated. Nevertheless, further studies are suggested to confirm this finding.

    Full Text Available OBJECTIVE: To determine the impact of periodontal treatment on serum levels of prohepcidin (the prohormone of hepcidin and systemic inflammation markers, as well as correlations among these markers, in patients with chronic periodontitis and chronic kidney disease who were not undergoing dialysis. METHODS: We included 56 chronic periodontitis patients, 36 with chronic kidney disease and 20 without systemic diseases and with normal renal function (control group. Chronic kidney disease was defined as suggested by the clinical practice guidelines in the National Kidney Foundation. Chronic periodontitis was defined through clinical attachment level and by probing pocket depth, according to the American Association of Periodontology. The inflammatory markers ultrasensitive C-reactive protein, interleukin-6, and prohepcidin were evaluated before and 3 months after periodontal treatment. RESULTS: The efficacy of periodontal treatment was confirmed by the improvement in clinical parameters of chronic periodontitis in the control and chronic kidney disease groups. Periodontal treatment resulted in significant reductions in ultrasensitive C-reactive protein, interleukin-6 and serum prohepcidin levels in both groups. Moreover, in multivariate linear regression, the reduction in prohepcidin after periodontal treatment was significantly and independently associated with interleukin-6 levels in the control group. CONCLUSIONS: By inducing a decline in the systemic inflammatory response and a decrease in serum prohepcidin, successful periodontal treatment may represent an important means of ameliorating the inflammatory burden seen in patients with chronic kidney disease.

    Full Text Available Aim. To investigate the effect of exenatide treatment on serum ghrelin levels in obese female patients with type 2 diabetes mellitus. Methods. Fourteen female patients with type 2 diabetes mellitus being treated with metformin and exenatide were enrolled. A mixed meal test was applied to the patients while continuing with their daily medications. Blood samples were taken before and at 60, 120, and 180 minutes following mixed meal test to measure serum total ghrelin, glucose, and insulin levels. The following week, exenatide treatment of the patients was paused for 24 hours and the same experimental procedures were repeated. Results. Serum ghrelin levels were suppressed significantly at 180 minutes with exenatide treatment compared with baseline (294.4±57.5 versus 234.5±59.4 pg/mL (p<0.001. Serum ghrelin levels at 180 minutes were statistically different when percentage change in serum ghrelin levels after mixed meal tests with and without exenatide usage were compared (p=0.001. Estimated total area under the curve values for serum ghrelin concentrations was also significantly lower with exenatide compared with omitted treatment (p=0.035. Conclusion. These results suggest that the effect of exenatide on weight loss may be related with the suppression of serum ghrelin levels, which is an orexigenic peptide.

    The current study applies the growing literature in the organizational sciences regarding levels of analysis issues to the analysis of substance abuse treatment beliefs. Research on clinicians' beliefs in substance abuse treatment is often based on the assumption that the beliefs are sufficiently shared by clinicians within a clinic and sufficiently vary across clinics that they can be treated as a group-level phenomenon. Further, efforts to introduce new innovations are often focused at the group or clinic level without testing this assumption, which can lead to failure to adopt or to successfully implement the innovation. We tested the assumption of sharedness by examining if there was sufficient agreement about treatment beliefs within clinics, within groups of clinics or within groups of clinicians to justify treating these aggregations as meaningful groups. Using three statistical approaches to examining level of analysis (Within and Between Analysis (WABA I), Intraclass Correlation Coefficients (ICC(1)), and rwg), we found that variability in treatment beliefs largely occurred at the individual rather than at the tested aggregate levels of analysis. These findings serve as an example of the importance of testing the assumption of shared perceptions in future research. PMID:17570604

    In this study the levels of 19 drugs of abuse were estimated throughout a wastewater treatment plant using polar organic chemical integrative samplers (POCIS), 24h composite samples and grab samples. Overall removal efficiencies and removals in between each treatment unit were calculated using load data for each sampling technique as well as removals that take into account the hydraulic residence time distribution of the treatment plant (time-shifted mass balancing approach). Amphetamine-type stimulants, cocaine and its major metabolite, benzoylecgonine and opioid levels determined with 24h composite samples were generally comparable to those obtained with POCIS and grab samples. Negative mass balances resulting from the estimation of overall removal efficiencies by POCIS, day-to-day mass balancing of 24h composite and grab sample data did not occur when the hydraulic retention time (HRT) distributions of the plant were taken into account for calculation. Among the compounds investigated, cocaine exhibited the highest overall removal (90%) while codeine had the lowest with 13%, respectively. Sampling between the treatment units revealed that highest removal occurs during biological treatment as compared to primary or secondary clarification. Methylenedioxyamphetamine (MDA), fentanyl, dihydrocodeine and heroin were not detected in wastewater at any of the sampling locations at the treatment plant regardless of the sampling technique. The study demonstrates the benefits of applying the time-shifted mass balancing approach to the calculation of removals of drugs of abuse during wastewater treatment.

    Full Text Available Vitamin B12 levels in the serum of 58 epileptic patients receiving only carbamazepine for at least 6 months were measured. Same number of epilepsy patients with no history of taking antiepileptic medicine were taken as control. The mean level of vitamin B12 in carbamazepine-treated epileptic patients was 265.5 pg/mL whereas it was 478.3 pg/mL in control. Increased duration of treatment of carbamazepine in epilepsy caused significantly decreased level of serum vitamin B12 (Pearson correlation coefficient, r = -0.9, p<0.0001. In conclusion, serum vitamin B12 level significantly decreased in relation to duration of carbamazepine treatment in epileptic patients.

    Potato tubers naturally contain a number of defense substances, some of which are of major concern for food safety. Among these substances are the glycoalkaloids and calystegines. We have here analyzed levels of glycoalkaloids (α-chaconine and α-solanine) and calystegines (A₃, B₂, and B₄) in potato tubers subjected to mechanical wounding, light exposure, or elevated temperature: stress treatments that are known or anticipated to induce glycoalkaloid levels. Basal glycoalkaloid levels in tubers varied between potato cultivars. Wounding and light exposure, but not heat, increased tuber glycoalkaloid levels, and the relative response differed among the cultivars. Also, calystegine levels varied between cultivars, with calystegine B4 showing the most marked variation. However, the total calystegine level was not affected by wounding or light exposure. The results demonstrate a strong variation among potato cultivars with regard to postharvest glycoalkaloid increases, and they suggest that the biosynthesis of glycoalkaloids and calystegines occurs independently of each other.

    Full Text Available BACKGROUND: Previous studies suggested that alterations in serum cortisol and DHEA-S levels may play a role in the pathophysiology of schizophrenia. AIM: To compare serum cortisol and DHEA-S levels between patients with schizophrenia and healthy controls and to evaluate their association with the response to antipsychotic treatment. MATERIAL AND METHODS: In this clinical prospective study were included 60 patients with schizophrenia and 40 healthy age and sex matched control subjects. Clinical evaluation of patients was performed using the Positive and Negative Symptom Scale. A questionnaire for socio-demographic and clinical data collection was used. For the purposes of the study, the examined group was divided in two subgroups: responders and nonresponders. Serum cortisol and DHEA-S levels were measured at baseline in all participants and after 3 and 6 weeks of the antipsychotic treatment in patients with schizophrenia. RESULTS: Patients with schizophrenia had significantly higher serum cortisol and DHEA-S levels in comparison to the control group. Responders had significantly higher serum cortisol and DHEA-S levels compared with nonresponders. CONCLUSION: Elevated serum cortisol and DHEA-S levels may play a role in the pathophysiology of schizophrenia and they may be related to positive response to antipsychotic treatment in patients with schizophrenia.

    Background In 2013, approximately 480,000 people developed active multidrug-resistant tuberculosis (MDR-TB), while only 97,000 started MDR-TB treatment. We sought to estimate the impact of improving access to MDR-TB diagnosis and treatment, under multiple diagnostic algorithm and treatment regimen scenarios, on ten-year projections of MDR-TB incidence and mortality. Methods We constructed a dynamic transmission model of an MDR-TB epidemic in an illustrative East/Southeast Asian setting. Using approximate Bayesian computation, we investigated a wide array of potential epidemic trajectories consistent with current notification data and known TB epidemiology. Results Despite an overall projected decline in TB incidence, data-consistent simulations suggested that MDR-TB incidence is likely to rise between 2015 and 2025 under continued 2013 treatment practices, although with considerable uncertainty (median 17% increase, 95% Uncertainty Range [UR] -38% to +137%). But if, by 2017, all identified active TB patients with previously-treated TB could be tested for drug susceptibility, and 85% of those with MDR-TB could initiate MDR-appropriate treatment, then MDR-TB incidence in 2025 could be reduced by 26% (95% UR 4–52%) relative to projections under continued current practice. Also expanding this drug-susceptibility testing and appropriate MDR-TB treatment to treatment-naïve as well as previously-treated TB cases, by 2020, could reduce MDR-TB incidence in 2025 by 29% (95% UR 6–55%) compared to continued current practice. If this diagnosis and treatment of all MDR-TB in known active TB cases by 2020 could be implemented via a novel second-line regimen with similar effectiveness and tolerability as current first-line therapy, a 54% (95% UR 20–74%) reduction in MDR-TB incidence compared to current-practice projections could be achieved by 2025. Conclusions Expansion of diagnosis and treatment of MDR-TB, even using current sub-optimal second-line regimens, is expected

    More than 2,000 drug courts in the United States provide supervision and substance-abuse treatment to thousands of offenders. Yet the treatment continuum from assessment to aftercare is underexplored. The effectiveness of the Level of Service Inventory-Revised (LSI-R) as a risk assessment tool is well established. However, fewer studies have considered its use in guiding treatment strategies. In using the LSI-R, the drug court program relied on the structured interview protocol (not the risk classification scores) to identify criminogenic needs that then helped determine placement in a high- or low-needs treatment track. To evaluate the effectiveness of these treatment placement decisions, this research used the LSI-R scores to examine individual and group differences (N = 182). Significant and substantive differences at the individual and group levels were found thus providing empirical support for using the LSI-R as a link between assessment and treatment. Implications for developing standards and practice protocols for drug courts are discussed.

    Background. Transmissible spongiform encephalopathies (TSEs) are a group of fatal neurodegenerative diseases caused by novel infectious agents referred to as prions. Prions appear to be composed primarily, if not exclusively, of a misfolded isoform of the cellular prion protein. TSE infectivity is remarkably stable and can resist many aggressive decontamination procedures, increasing human, livestock and wildlife exposure to TSEs. Findings. We tested the hypothesis that UV-ozone treatment reduces levels of the pathogenic prion protein and inactivates the infectious agent. We found that UV-ozone treatment decreased the carbon and prion protein content in infected brain homogenate to levels undetectable by dry-ashing carbon analysis or immunoblotting, respectively. After 8 weeks of ashing, UV-ozone treatment reduced the infectious titer of treated material by a factor of at least 105. A small amount of infectivity, however, persisted despite UV-ozone treatment. When bound to either montmorillonite clay or quartz surfaces, PrPTSE was still susceptible to degradation by UV-ozone. Conclusion. Our findings strongly suggest that UV-ozone treatment can degrade pathogenic prion protein and inactivate prions, even when the agent is associated with surfaces. Using larger UV-ozone doses or combining UV-ozone treatment with other decontaminant methods may allow the sterilization of TSE-contaminated materials. ?? 2009 Aiken et al; licensee BioMed Central Ltd.

    Full Text Available Recurrent aphthous ulcers (RAUs are the most common lesion found in the oral cavity. There is no definitive cure for RAUs and current treatments are aimed at minimizing symptoms. Since low-level laser therapy (LLLT modulates inflammatory responses, and promotes pain reduction and cellular biostimulation, LLLT can be suggested as an alternative treatment for RAUs. The literature concerning the potential of LLLT in the treatment of RAUs was evaluated. A systematic literature review identified 22 publications, of which only 2 studies were adopted. The eligibility criteria consisted of randomized controlled trials (RCTs. Both RCTs achieved significant results concerning LLLT and pain-level reductions and reduced healing times. Despite the variance in irradiation conditions applied in both studies, very similar wavelengths were adopted. There is accordingly strong evidence that wavelength plays an important role in RAU treatment. Taking into account the different parameters applied by selected RCTs, it is not possible to suggest that a specific protocol should be used. However, in light of the significant results found in both studies, LLLT can be suggested as an alternative for RAU treatment. Additional RCTs should be performed in order to reach a clinical protocol and better understand the application of LLLT in RAU treatment.

    Peripheral sensory neuropathy treatment is one of the common treatment problems and causes morbidity and mortality in people suffering from that. Although treatment depends on the underlying cause of the condition, nevertheless, in some cases, there is no cure for it, and it requires palliative and symptomatic treatment. In laboratory studies, low-level laser has been effective in the nerves protection and restoration. The aim of this article is to investigate the clinical efficacy of low-level laser on improvement of the peripheral somatosensory neuropathy. Search in the articles published up to 30 October 2015 (full text and abstracts) in databases PubMed (Medline), Cochrane library, Physiotherapy Evidence Database was performed. The studies of low-level laser trials on patients with peripheral neuropathy were carried out and evaluated in terms of the exclusion criteria. There are 35 articles among which 10 articles had the intended and required criteria. 1, 3, and 6 articles study the patients with diabetes, neuropathy caused by trauma, and carpal tunnel syndrome, respectively. In six studies, laser led to a reduction in sensory impairment and improvement of the physiological function of the sensory nerves. In these articles, lasers (Diode, GaAlAs, He-Ne) had wavelength range 660-860 nm, radiation power 20-250 mW, energy density 0.45-70 J/cm(2). The intervention sessions range was 6-21 times and patient follow-up was 0-6 months. According to the results of these studies, low-level laser therapy can improve sensory function in patients with peripheral somatosensory neuropathy, although little research have not been done, laser treatment regimens are varied and do not recommend a specific treatment protocol. It seems it requires more research to sum up better, particularly in relation to diabetes.

    Full Text Available Background: Serum estradiol level is a controversial prognostic factor in the outcome of labial adhesion. The aim of this study was to evaluate serum estradiol levels and topical estrogen response in patients with labial adhesion.Methods: A prospective interventional study was conducted among girls with labial adhesion that referred to Pediatrics clinic in Taleghani University Hospital, Gorgan city, Iran in 2011. One hundred patients entered the study. The diagnosis was conducted by clinical examination of vestibule area. Inclusion criteria were, three months to eight years old prepuberty girls, no ambiguous genitalia, lack of vulvovaginitis symptoms, labial adhesion more than twenty five percent, no history of previous topical estrogen treatment since two weeks ago and previous incomplete treatment. The patients who did not use proper amount and duration of drug and also with adverse drug reactions during treatment period were excluded from the study. Results: The maximum frequency of labial adhesion was in the group of less than one year old. The minimum frequency of labial adhesion was in the 7-8 years old group. Eighty six patients had complete or partial remission. No evidence of an improvement was observed in fourteen children. Severity of adhesions did not worsen in our patients. Serum estradiol levels were lower in patients who had a positive response to treatment. There were significant differences in serum estradiol levels between full or relative improvement with no improvement groups (P=0.044.Conclusion: Findings of this study showed that the labial adhesion patients with low serum estradiol level had better treatment response after using topical estrogen.

    Weight gain is a common adverse effect associated with the use of most typical and atypical antipsychotic. Aim of this study was to investigate serum prolactin, leptin, cholesterol, triglyceride, lipoproteins, such high density lipoprotein (HDL), and low density lipoprotein (LDL) levels in patients with Parkinson's disease (PD)-related psychosis during long-term medication with atypical antipsychotic. The study population comprised 40 patients, who were divided into 4 groups: olanzapine (n=10), risperidone (n=10), seroquel (n=10) monotherapy, a group of 10 patients receiving only antiparkinson drugs and a control group of 8 healthy persons. The patients were evaluated at baseline and at the sixth and twelfth week according to the Positive and Negative Syndrome Scale (PANSS), body mass index (BMI), and fasting serum prolactin, leptin, lipids and lipoproteins levels. Treatment of patients with olanzapine caused marked increase of serum LDL, cholesterol, triglyceride, and leptin levels (p<0,02). No changes in HDL concentrations. There was positive relationship between serum leptin, lipid levels and BMI. However, treatment of patients with seroquel did not cause changes in serum prolactin, leptin, lipids, and lipoproteins levels. Our results suggest that treatment of patients with PD-related psychosis with seroquel appears to have minimal influence on serum leptin, prolactin, lipids, lipoproteins and BMI compared with olanzapine and risperidone.

    The purpose of this study was to investigate the blood levels of methadone in participants receiving methadone for the treatment of opioid dependence. After stabilization on methadone for four weeks, blood samples from 95 participants were collected between treatment weeks 4 and 12, before and after receiving doses of methadone, and its blood levels were measured. A multiple linear regression model was used to examine the association between methadone blood levels and the outcomes of methadone maintenance treatment (MMT). Outcome differences between participants who had high (≥2) or low (methadone was not correlated with the clinical outcome of MMT with the moderate range of doses given. However, the retention of patients who had a free peak-to-trough ratio >2 was significantly poorer than those whose ratio was methadone levels is unlikely to be effective for guiding dosing decisions in situations where compliance with MMT is already very high or when the methadone dose is no longer the dominant factor in determining the clinical outcome. However, monitoring plasma methadone levels is still helpful for guiding the dosage for patients with a rapid metabolism.

    Full Text Available Monoclonal antibodies restricted to Mycobacterium tuberculosis can measure epitope-specific antibody levels in a competition assay. Immunodominant epitopes were defined from clinical samples and related to the clinical spectrum of disease. Antibody to the immunodominant epitopes was associated with HLA-DR15. Occupational exposure showed a different response and was consistent with recognition of dormancy related proteins and protection despite exposure to tuberculosis. Studies in leprosy revealed the importance of immune deviation and the relationships between T and B cell epitopes. During treatment, antibody levels increased, epitope spreading occurred, but the affinity constants remained the same after further antigen exposure, suggesting constraints on the process of epitope selection. Epitope-specific antibody levels have a potential role as biomarkers for new vaccines which might prevent the progression of latent to active tuberculosis and as tools to measure treatment effects on subpopulations of tubercle bacilli.

    We retrospectively investigated the patterns of locoregional relapse and survival of patients to evaluate whether sparing level Ib lymph nodes by intensity-modulated radiotherapy (IMRT) in the treatment of nasopharyngeal carcinoma was feasible. One hundred and twenty nasopharyngeal carcinoma patients received treatment with level Ib lymph nodes spared by IMRT between January 2005 and August 2008 in our center. Before treatment, each patient underwent enhanced magnetic resonance imaging of the nasopharynx and neck. Patients with negative cervical lymph nodes received radiotherapy to the nasopharynx, skull base and upper neck drainage areas, while patients with cervical lymph node involvement received treatment to the whole neck. The prescription doses were 66-70.4 Gy/30-32 fractions to the gross tumor volume of nasopharynx, 66 Gy to the positive neck nodes, 60 Gy to the high-risk clinical target volume and 54 Gy to the low-risk clinical target volume. Patients staged III, IV A/B or II also received chemotherapy. The median follow-up of these 120 patients was 54 months. The 5-year local control, regional control, distant metastasis-free and overall survival rates were 90.7, 96.5, 84.8 and 81.4 %, respectively. Four patients suffered regional recurrence: 2, 1 and 1 experienced regional recurrence in level II, retropharyngeal and parotid lymph nodes, respectively. In nasopharyngeal carcinoma patients with negative level Ib lymph nodes who are treated with level Ib-sparing IMRT, regional lymph node recurrence alone is rare. Therefore, sparing level Ib lymph nodes by IMRT is feasible in selected patients.

    Full Text Available Introduction: More than 60 years after the introduction of modern psychopharmacology, electroconvulsive therapy (ECT continues to be an essential therapeutic modality in the treatment of mental disorders, but its mechanism of action remains unclear. Hormones play an essential role in the development and expression of a series of behavioral changes. One aspect of the influence of hormones on behavior is their potential contribution to the pathophysiology of psychiatric disorders and the mechanism of action of psychotropic drugs and ECT.Objective: We measured blood levels of the hormone cortisol in patients with unipolar depression according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV and compared results with levels found in healthy adults.Method: Blood cortisol levels were measured before the beginning of treatment with ECT, at the seventh session, and at the last session, at treatment completion. Depression symptoms were assessed using the Beck Depression Inventory (BDI.Results: Cortisol levels remained stable in both men and women between the seventh and the last sessions of ECT; values ranged from 0.686±9.6330 g/dL for women, and there was a mean decrease of 5.825±6.0780 g/dL (p = 0.024. Mean number of ECT sessions was 12. After the seventh and the last ECT sessions, patients with depression and individuals in the control group had similar cortisol levels, whereas BDI scores remained different.Conclusion: Cortisol levels decreased during ECT treatment. ECT seems to act as a regulator of the hypothalamic-pituitaryadrenal axis.

    Full Text Available S100ß a neurotrophic factor mainly released by astrocytes, has been implicated in the pathogenesis of bipolar disorder. Thus, lithium may exert its neuroprotective effects to some extent through S100ß. Furthermore, the possible effects of lithium on astrocytes as well as on interactions between neurons and astrocytes as a part of its mechanisms of actions are unknown. This study was undertaken to determine the effect of lithium on S100β in neurons, astrocytes and a mixture of neurons and astrocytes. Rat primary astrocyte, neuronal and mixed neuro-astroglia cultures were prepared from cortices of 18-day's embryos. Cell cultures were exposed to lithium (1mM or vehicle for 1day (acute or 7 days (chronic. RT-PCR and ELISA determined S100β mRNA and intra- and extracellular protein levels. Chronic lithium treatment significantly increased intracellular S100β in neuronal and neuro-astroglia cultures in comparison to control cultures (P<0.05. Acute and chronic lithium treatments exerted no significant effects on intracellular S100β protein levels in astrocytes, and extracellular S100β protein levels in three studied cultures as compared to control cultures. Acute and chronic lithium treatments did not significantly alter S100β mRNA levels in three studied cultures, compared to control cultures. Chronic lithium treatment increased intracellular S100ß protein levels in a cell-type specific manner which may favor its neuroprotective action. The findings of this study suggest that lithium may exert its neuroprotective action, at least partly, by increasing neuronal S100ß level, with no effect on astrocytes or interaction between neurons and astrocytes.

    The acidic and alkaline low level radioactive liquid waste (LLW) generated during the concentration of high level radioactive liquid waste (HLW) prior to vitrification and ion exchange treatment of intermediate level radioactive liquid waste (ILW), respectively are decontaminated by chemical co-precipitation before discharge to the environment. LLW stream generated from the ion exchange treatment of ILW contained high concentrations of carbonates, tributyl phosphate (TBP) degraded products and problematic radio nuclides like (106)Ru and (99)Tc. Presence of TBP degraded products was interfering with the co-precipitation process. In view of this a modified chemical treatment scheme was formulated for the treatment of this waste stream. By mixing the acidic LLW and alkaline LLW, the carbonates in the alkaline LLW were destroyed and the TBP degraded products got separated as a layer at the top of the vessel. By making use of the modified co-precipitation process the effluent stream (1-2 μCi/L) became dischargeable to the environment after appropriate dilution. Based on the lab scale studies about 250 m(3) of LLW was treated in the plant. The higher activity of the TBP degraded products separated was due to short lived (90)Y isotope. The cement waste product prepared using the TBP degraded product was having good chemical durability and compressive strength. Copyright © 2011 Elsevier B.V. All rights reserved.

    Background More municipal water treatment plants are using chloramines as a disinfectant in order to reduce carcinogenic by-products. In some instances, this has coincided with an increase in lead levels in drinking water in those systems. Lead in drinking water can be a significant health risk. Objectives We sought to test the potential effect of switching to chloramines for disinfection in water treatment systems on childhood blood lead levels using data from Wayne County, located in the central Coastal Plain of North Carolina. Methods We constructed a unified geographic information system (GIS) that links blood lead screening data with age of housing, drinking water source, and census data for 7,270 records. The data were analyzed using both exploratory methods and more formal multivariate techniques. Results The analysis indicates that the change to chloramine disinfection may lead to an increase in blood lead levels, the impact of which is progressively mitigated in newer housing. Conclusions Introducing chloramines to reduce carcinogenic by-products may increase exposure to lead in drinking water. Our research provides guidance on adjustments in the local childhood lead poisoning prevention program that should accompany changes in water treatment. As similar research is conducted in other areas, and the underlying environmental chemistry is clarified, water treatment strategies can be optimized across the multiple objectives that municipalities face in providing high quality drinking water to local residents.

    Psoriasis has been considered as systemic disorder. Lipocalin-2 might be a link between psoriasis and its comorbidities. Aim of the study was to investigate the associations between serum lipocalin-2 levels and the disease activity, markers of inflammation or metabolic disturbances and changes after topical treatment in psoriatic patients. Thirty-seven individuals with active plaque-type psoriasis and 15 healthy controls were recruited. Blood samples were collected before and after 14 days of therapy. Serum lipocalin-2 concentrations were examined by enzyme-linked immunosorbent assay. The results were correlated with Psoriasis Area and Severity Index (PASI), body mass index (BMI), inflammatory and biochemical markers, lipid profile and with effectiveness of topical treatment. Lipocalin-2 serum levels were significantly increased in psoriatic patients in comparison to the controls (p = 0.023). No significant correlations with indicators of inflammation, nor BMI or PASI were noted. A statistical association between lipocalin-2 and low-density lipoprotein-cholesterol was shown. After topical treatment serum lipocalin-2 level did not significantly change (p = 0.9), still remaining higher than in the controls, despite clinical improvement. Lipocalin-2 might be a marker of psoriasis and convey cardiovascular or metabolic risk in psoriatic patients, but may not be a reliable indicator of inflammation, severity of psoriasis nor efficacy of antipsoriatic treatment.

    The objective of this study was to assess the efficacy of fluoxetine (FX) treatment in cocaine dependent methadone (MTD) maintenance patients, to assess decrease or interruption of cocaine use and pharmacokinetic interaction between fluoxetine an methadone plasma levels. The sample was composed of 11 patients with DSM IV criteria for opioid and cocaine dependence. We added Fluoxetine (20 mg per day) during 9 weeks in Majadahonda Drug Program. All patients were in methadone program a mean of 7.5 months. We made a psychiatry interview and the baseline severity of the mood disorder was assessed with the Clinical Global Impression ICG for therapeutic improvement. Cocaine use and fluoxetine treatment was measured in urine analysis and pharmacokinetic interaction between FX-MTD were measured with plasma levels of methadone. Fluoxetine was well tolerated combined with methadone. FX-MTD interaction didn't occur, resulting in no increased of MTD plasma level to dose before and after fluoxetine treatment. After fluoxetine treatment decreased cocaine use, changed cocaine tract from injected to smoked and improvement depressive symptoms.

    Low level laser treatment (LLLT) is currently being used for various disorders, but with no convincing scientific evidence. Most recently we have noticed an increase in published randomised controlled trials (RCTs) that have focused on its applications in wound healing, scarring, disorders of the temporomandibular joint (TMJ), oral mucositis, and dental pain. Our aim therefore was to assess the scientific evidence about its current efficacy in maxillofacial surgery. We reviewed PubMed from January 2003 to January 2013 using the key phrase "low level laser treatment". Our inclusion criterion was intervention studies in humans of more than 10 patients. We excluded animal studies and papers in languages other than English, French, and German. We found 45 papers that we screened independently. The resulting full texts were scrutinised by two authors who awarded a maximum of 5 points using the Jadad scale for assessing the quality of RCT, and extracted the data according to sample size, variables of LLLT, the authors' conclusions, and the significance of the result. LLLT seems to be effective for the treatment of oral mucositis after treatment for head and neck cancer. However, it cannot yet be considered a valid treatment for disorders of the TMJ. It seems to improve gingival healing, and myofacial and dental pain.

    Our objective was to determine whether there is a relationship between low antiphospholipid (aPL) antibody levels and the obstetrical complications of antiphospholipid syndrome (APS) and to analyze the impact of conventional APS treatment in patients with low aPL levels. To this end, we retrospectively reviewed the files of all patients referred to our unit (2003-2010) for unexplained pregnancy morbidity, with an aPL test result. We compared patients with APS confirmed by Sapporo criteria (Group 1) with patients with APS-like obstetrical complications with an aPL titer below the intermediate titer (Group 2). Overall, 57 patients were included (25 in Group 1; 32 in Group 2). Obstetrical events were recurrent spontaneous abortion <10th week of gestation (n=9 patients in Group 1; n=13 patients in Group 2), fetal death (n=11 and 16, respectively), preeclampsia (n=5 in Group 1; n=6 in Group 2). The total number of obstetrical events per patient was very similar before APS treatment (3 [1-8] in Group 1; 3 [1-6] in Group 2) and decreased significantly after APS treatment to 0 [0-2] and 0 [0-2], respectively (p<0.05). The incidence of premature births and the characteristics of neonates were similar in the two groups. In this study, treatment of patients with low aPL levels and APS-like obstetrical events was associated with outcomes similar to those found in otherwise normal women with recurrent miscarriage or other adverse events. However, properly designed treatment trials would be required to prove the benefit of such treatments.

    Psoriasis is a chronic autoimmune disease involving a complex network of cytokines such as interleukin (IL)-6. We tested the hypothesis that serum IL-6 level is a useful indicator of disease activity and predicts the treatment response to biologics in patients with psoriasis. We analyzed 113 psoriasis patients treated with biologics (73 with infliximab [IFX], 24 with adalimumab [ADA], and 16 with ustekinumab [UST]) in our hospital. Disease severity was assessed using the Psoriasis Area and Severity Index (PASI) score, and Disease Activity Score 28 based on C-reactive protein (DAS28-CRP). Before treatment, serum IL-6 levels significantly correlated with PASI scores in patients with psoriasis vulgaris (r = 0.432, p = 0.001) and with DAS28-CRP in patients with psoriatic arthritis (r = 0.469, p = 0.010). Serum IL-6 levels were significantly decreased by IFX (from 4.8 to 1.5) and ADA (from 2.5 to 1.4) therapy. In psoriatic arthritis, serum IL-6 levels at the endpoint tended to be lower in patients who achieved DAS28-CRP psoriasis and for predicting responsiveness of joint symptoms to biologic treatment.

    BACKGROUND: In addition to its glucose-lowering effect, metformin treatment has been suggested to improve lipidaemia in patients with type 2 diabetes. In contrast, in patients with type 1 diabetes (T1DM), information about the effect of metformin treatment on lipidaemia is limited. In this study...... disease did not change conclusions. In statin users (metformin: n = 22, placebo: n = 13), metformin significantly lowered levels of LDL and non-HDL cholesterol by approximately 0.5 mmol/l compared with placebo (adjusted for changes in statin dose or agent: p = 0.048 and p = 0.033 respectively).

    Volume reduction is a cost saving method for the final disposal of radioactive waste. On one hand, arc plasma heating can provide sufficient heat independent of the chemical and physical properties of waste, therefore enabling stable heating at high treatment rates. CRIEPI (central research institute of electric power industry) focused on the advantages of arc plasma heating, and has clarified that arc plasma heating can be used in a simultaneous melting treatment process for low-level miscellaneous mixed solid waste, generated from nuclear power plants for volume reduction, and in the stabilization of radionuclides.

    Background and aims Muscular pain in the facial region is the most common cause of facial pains. Myofascial pain dysfunction syndrome (MPDS) is one of the most important facial muscle disorders comprising of signs and symptoms including pain during function, tenderness in the muscles of mastication and restricted jaw movement. Due to the lack of an accepted therapeutic approach, the purpose of this paper was to find an effective treatment to decrease the pain of such patients. Considering the analgesic and anti-inflammatory action of laser therapy, the effects of low level laser (Ga-Al-As) in the treatment of MPDS patients referred to Tehran University of Medical Sciences Faculty of Dentistry, were investigated in the present study. Materials and methods This study was a quasi-experimental research. Twenty-two MPDS patients were selected from those referred to Department of Oral Medicine, Tehran University of Medical Sciences Faculty of Dentistry. Clinical examination was performed at six stages in the following order: prior to the treatment, at 2 and 4 weeks after treatment, and monthly thereafter for a 3-months follow-up. All patients underwent low-level laser therapy for 4 weeks (12 sessions). Variables such as pain severity, pain of cheek region, pain frequency, tenderness of masticatory muscles, click, and mouth opening were evaluated at each stage. Numerical variables were investigated using Analysis of Variance test for repeated measures whereas ranking variables were studied by non-parametric Kruskal-Wallis test. Results At the end of treatment period, pain severity, pain of cheek region, pain frequency, tenderness of masseter, temporalis, medial pterygoid, and lateral pterygoid muscles showed significant improvement as compared with the commencement of any treatment which continued during the 3-months post-treatment (ppain and decrease the tenderness of masticatory muscles among MPDS patients through a continuous and regular therapeutic program.

    Objective: To observe the effect of acupuncture on blood oxygen free radical (OFR) and nitric oxide(NO) levels in the treatment of apoplectic sequelae. Methods: A total of 61 cases of apoplectic patients were subject-ed into this study and randomly divided into "JIN San Zhen" group (n=30) and control group (n=31). Blood lipid per-oxidase (LPO), superoxide dismutase (SOD), glutathione peroxidase(GSH-Px) and nitric oxide (NO) contents beforeand after acupuncture treatment were determined with radioimmunoassay. In both groups, acupuncture was given oncedaily, six times a week, with 4 weeks being a therapeutic course and with the interval between two weeks being aweek, 3 courses all together. In "JIN San Zhen" group, acupoints of "JIN San Zhen" were used predominately, whilein control group, scalp-point Motor Sensory Area (MS 8) was used as the main point. Results: Self-comparison showedthat after 3 courses of treatment, in both groups, LPO and NO levels decreased significantly ( P < 0.05 - 0.01 ), SODand GST-Px values increased considerably ( P< 0.05 - 0.01 ). Comparison between two groups indicated that the ef-fects of "JIN San Zhen" group are significantly superior to those of control group in raising blood SOD and GST-Px lev-els ( P< 0.05- 0.01 ) and in lowering blood NO content ( P< 0.01 ). Analysis on the correlation between the restora-tion of neural function and the changes of LPO, SOD and GST-Px levels suggested that the effect of acupuncture in im-proving neural function may be related to changes of the aforementioned indexes. Conclusion: Acupuncture therapy cansignificantly lower blood LPO and NO levels and evidently raise blood SOD and GST-Px levels in stroke patients.

    The category of sludges, filter cakes, and other waste processing residuals represent the largest volume of low-level mixed (hazardous and radioactive) wastes within the US Department of Energy (DOE) complex. Treatment of these wastes to minimize the mobility of contaminants, and to eliminate the presence of free water, is required under the Federal Facility Compliance Act agreements between DOE and the Environmental Protection Agency. In the text, we summarize the currently available data for several of the high priority mixed-waste sludge inventories within DOE. Los Alamos National Laboratory TA-50 Sludge and Rocky Flats Plant By-Pass Sludge are transuranic (TRU)-contaminated sludges that were isolated with the use of silica-based filter aids. The Oak Ridge Y-12 Plant West End Treatment Facility Sludge is predominantly calcium carbonate and biomass. The Oak Ridge K-25 Site Pond Waste is a large-volume waste stream, containing clay, silt, and other debris in addition to precipitated metal hydroxides. We formulate ``simulants`` for the waste streams described above, using cerium oxide as a surrogate for the uranium or plutonium present in the authentic material. Use of nonradiological surrogates greatly simplifies material handling requirements for initial treatability studies. The use of synthetic mixtures for initial treatability testing will facilitate compositional variation for use in conjunction with statistical design experiments; this approach may help to identify any ``operating window`` limitations. The initial treatability testing demonstrations utilizing these ``simulants`` will be based upon vitrification, although the materials are also amenable to testing grout-based and other stabilization procedures. After the feasibility of treatment and the initial evaluation of treatment performance has been demonstrated, performance must be verified using authentic samples of the candidate waste stream.

    Stathmin is a prognostic marker in many cancers, including endometrial cancer. Preclinical studies, predominantly in breast cancer, have suggested that stathmin may additionally be a predictive marker for response to paclitaxel. We first evaluated the response to paclitaxel in endometrial cancer cell lines before and after stathmin knock-down. Subsequently we investigated the clinical response to paclitaxel containing chemotherapy in metastatic endometrial cancer in relation to stathmin protein level in tumors. Stathmin level was also determined in metastatic lesions, analyzing changes in biomarker status on disease progression. Knock-down of stathmin improved sensitivity to paclitaxel in endometrial carcinoma cell lines with both naturally higher and lower sensitivity to paclitaxel. In clinical samples, high stathmin level was demonstrated to be associated with poor response to paclitaxel containing chemotherapy and to reduced disease specific survival only in patients treated with such combination. Stathmin level increased significantly from primary to metastatic lesions. This study suggests, supported by both preclinical and clinical data, that stathmin could be a predictive biomarker for response to paclitaxel treatment in endometrial cancer. Re-assessment of stathmin level in metastatic lesions prior to treatment start may be relevant. Also, validation in a randomized clinical trial will be important.

    Full Text Available The measurement of glycemia in subjects with renal failure, thus treated with hemodialysis, or peritoneal dialysis, is clinically relevant, since glucose levels may influence the determination of other solutes, such as creatinine, as well as some ions, such as sodium, whose degree of removal during dialysis sessions should be controlled carefully. Also, glucose levels should be controlled to avoid possible events of hypoglycemia during the treatment, especially in diabetic subjects. Indeed, even cases of hypoglycemic coma are documented. The glucose measurement during the dialysis treatment can be performed with different sensors and technologies: for instance, with traditional glucose meters, with instruments for continuous glucose monitoring, or with optical sensors. The aim of this review study was to analyze these different approaches and briefly discuss possible advantages and limitations.

    The os peroneum is a sesamoid bone in the peroneus longus tendon. Fractures of the os peroneum are rare. Some authors recommend surgery for active patients. A 41-year-old male professional tennis coach sustained a minimally displaced fracture of the os peroneum. He was treated with restricted weightbearing for 2 weeks, followed by physical therapy and gradual return to activities. He returned to tennis 8 weeks after injury. Followup 7 years after the injury showed he had full strength, full motion, and a radiographically healed os peroneum. The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale score was 100 and Ankle Activity Score and Tegner Activity Level Scale were unchanged from those before injury. Fracture of the os peroneum is a rare injury and treatment recommendations are based largely on very small series and case reports. Proposed treatment strategies for fracture of the os peroneum include nonoperative treatment, fixation of the fracture, excision of the bone with direct repair of the tendon, and tenodesis of the peroneus longus to the peroneus brevis. Although some surgeons suggest fracture of the os peroneum should be treated operatively in active patients, this case shows nonoperative treatment allowed pain-free return to activities in a high-level athlete with a minimally-displaced fracture.

    Full Text Available This study investigated the level of knowledge held by dentists about the possible treatment plan procedures for periodontal ligament injuries after dentoalveolar trauma. A 5-item self-applied questionnaire was prepared with questions referring to the professional profile of the interviewees and to the treatment plan they would propose for periodontal ligament injuries secondary to dentoalveolar trauma. The questionnaires were filled out by 693 dentists attending the 23rd Annual Meeting of the Brazilian Society for Dental Research, and the data obtained were subjected to descriptive analysis. Either the chi-square test or Fisher's exact test was applied to assess associations among variables, at a 5% level of significance. The results revealed that dentists experienced difficulty in establishing a treatment plan for subluxation, and for extrusive, lateral and intrusive luxations. In general, holding a dental specialty degree had no influence on the knowledge about treatment plan procedures for the most severe injuries. It could be concluded that the dentists participating in this study, whether specialists or not, did not have sufficient knowledge to treat most of the periodontal ligament injuries resulting from dentoalveolar trauma adequately.

    Multi-dimensional Treatment Foster Care (MTFC), recently renamed Treatment Foster Care Oregon for Adolescents (TFCO-A) is an internationally recognised intervention for troubled young people in public care. This paper seeks to explain conflicting results with MTFC by testing the hypotheses that it benefits antisocial young people more than others and does so through its effects on their behaviour. Hard-to-manage young people in English foster or residential homes were assessed at entry to a randomised and case-controlled trial of MTFC (n = 88) and usual care (TAU) (n = 83). Primary outcome was the Children's Global Assessment Scale (CGAS) at 12 months analysed according to high (n = 112) or low (n = 59) baseline level of antisocial behaviour on the Health of the Nation Outcome Scales for Children and Adolescents. After adjusting for covariates, there was no overall treatment effect on CGAS. However, the High Antisocial Group receiving MTFC gained more on the CGAS than the Low group (mean improvement 9.36 points vs. 5.33 points). This difference remained significant (p care but only for those with higher levels of antisocial behaviour. Further work is needed on whether such benefits persist, and on possible negative effects of this treatment for those with low antisocial behaviour.Trial Registry Name: ISRCTNRegistry identification number: ISRCTN 68038570Registry URL: www.isrctn.com.

    The effects of metformin and pioglitazone on ghrelin, a physiologic regulator of appetite and food intake, have not been clearly established. In a randomized clinical trial, we randomly assigned 60 type 2 diabetic patients to either metformin (Group A; n=30) or pioglitazone (Group B; n=30) treatment groups. The groups were similar in their baseline characteristics. A standard fasting 75 g oral glucose tolerance test was performed at time zero before starting metformin or pioglitazone, and 3 months later. After 3 months of treatment, pioglitazone, but not metformin, was significantly associated with weight gain. Both groups experienced a significant reduction in fasting plasma glucose (ppioglitazone group had a significant reduction in preprandial ghrelin levels after treatment (ppioglitazone on ghrelin was independent of changes in body weight, body mass index, glucose control, insulin resistance, and plasma insulin. In conclusion, treatment with pioglitazone is associated with a decrease in preprandial ghrelin levels and therefore, the weight gain and increased food intake related to pioglitazone use cannot be explained by its effects on ghrelin. The effect of pioglitazone on ghrelin is independent of changes in body weight, body mass index, plasma insulin, insulin resistance, or glucose control.

    Full Text Available Stroke is a leading cause of mortality and morbidity worldwide. Few therapeutic options with proven efficacy are available for the treatment of this disabling disease. Lithium is the gold standard treatment for bipolar disorder. Moreover, lithium has been shown to exhibit neuroprotective effects and therapeutic efficacy as a treatment of other neurological disorders. This study was undertaken to examine the effects of lithium on brain inflammatory mediators levels, fever, and mortality in postischemic stroke rats. Ischemic stroke was induced by occlusion of the mid cerebral artery (MCAO. Pretreatment with a single dose of lithium at 2 hours before MCAO induction significantly reduced the elevation in interleukin- (IL- 6 and prostaglandin E2 levels in brain of post-MCAO rats, as compared to vehicle-treated animals. On the other hand, lithium did not affect the elevation in IL-1α, IL-10, IL-12, and tumor necrosis factor-α levels in brain of post-MCAO rats. Moreover, pretreatment with lithium did not alter post-MCAO fever and mortality. These results suggest that acute pretreatment with a single dose of lithium did not markedly affect post-MCAO morbidity and mortality in rats.

    Adrenomedullin (AM) is a 52-amino acid peptide that causes vasodilatation by increased synthesis of nitric oxide. Its production by different cells such as cardiac myocytes, smooth muscle, endothelial, and oncogenic cells is stimulated by inflammatory processes. It has been shown that in the presence of inflammation in the urinary system, concentration of AM increases. In this study, we measured urinary AM in children with acute pyelonephritis before and after treatment and compared its level with that in healthy children. In a case-control study, 31 children with clinical and paraclinical documentation of pyelonephritis (case group) and 30 healthy children without pyelonephritis or other infections (control group) were studied. Urinary AM were measured on spot urine samples by high-performance liquid chromatography, and creatinine was measured by spectrophotometry to report the AM-creatinine ratio. Urinary AM-creatinine ratios were 61.3 +/- 119.4 pg/mg and 4.26 +/- 11.4 pg/mg, respectively, in the case and control groups (P = .01). After treatment of pyelonephritis in the patients of the case group, this ratio decreased to 13.1 +/- 21.9 (P = .048). The coefficient correlation between urinary AM and leukocytes count was 0.252 (P = .17). Urinary AM levels were 1896 +/- 1748 pg/dL and 391 +/- 477 pg/dL in the patients with 4+ versus negative C-reactive protein levels, respectively (P = .008). Urinary AM increases in the course of pyelonephritis and decreases significantly after treatment.

    Among patients with breast cancer, few studies have examined the pattern of change of physical activity levels over time or the predictive factors for this change. Particularly sparse are studies comparing pre-surgical physical activity levels with those 12 months post-surgery. Patients with a primary operable breast cancer (N = 267) filled in the Physical Activity Computerised Questionnaire before breast surgery and 1, 3, 6 and 12 months post-operatively. Patient-, disease- and treatment-related factors were prospectively collected. Total physical activity level and occupational, sport and household activity levels were significantly decreased the first month post-operatively and did not recover during the first year after surgery. 'Being employed' was a predictive factor for a larger decrease of the total activity level, comparing the pre-operative and 12 months post-surgery stages. Having a spouse, a pN2-3 lesion and over 20 lymph nodes dissected predicted a decrease in occupational activity. Advanced age and smoking behaviour predicted a decrease in sport activities, and not having a spouse predicted a decrease in household activities. This study showed that 1 year after breast cancer surgery, pre-operative physical activity levels were not recovered. Breast cancer patients, and in particular those at risk for a decreased physical activity level, should be identified, encouraged and guided to increase their activities.

    Full Text Available The primary aim of this study was to analyze the current level of evidence available on the surgical management of Slipped Capital Femoral Epiphysis (SCFE. Secondary aims were to correlate the level of evidence with the impact factor of the journal to evaluate the level of evidence over time, and to evaluate the geographic distribution of the studies. Therapeutic studies published in English between January 1991 and August 2014 that reported on SCFE were identified via electronic search was performed using the databases PubMed, EMBASE, and the Cochrane Library. The search terms used included: Slipped capital femoral epiphyses OR SCFE OR Slipped upper femoral epiphyses OR SUFE AND Management OR Treatment. Correlation between the level of evidence and the impact factor of the journal were analyzed together with linear regression models to reveal any significant trends over time. A total of 1516 studies were found, of which 321 were included in the final analysis. The most frequent study type was the case series (51.1% followed by case reports (22.4% and expert opinion (14.0%. Randomized control trial accounted for only 0.6%. The Journal of Pediatric Orthopedics (American had the most studies (22.6% and the highest number of level 2 (n=1 and level 3 (n=15 type evidence. There was no progression of level of evidence over time. There was no correlation between level of evidence and impact factor of journal. The majority of therapeutic studies on SCFE are of low level of evidence. High-level RCTs are difficult to perform in pediatric orthopedic surgery, however the management of SCFE would benefit from well-designed, multicenter, clinical RCTs to advance evidence-based practice.

    Full Text Available Background/Aim. Alveolar osteitis (AO is the extraction wound healing disorder with a presence of severe pain. Low level laser therapy stimulates cell metabolism and microcirculation, have has pronounced analgesic, antiedematous and anti-inflammatory effect and speeds up wound healing process. The aim of this study was to present results of clinical research that examined the effectiveness of low level laser in pain relief and healing of extraction wounds with alveolar osteitis in the lower jaw which was formed on the second day after tooth extraction. Methods. The study was conducted on 60 subjects divided into the study and the control group. In both groups extraction wounds were processed in similar way, except that in the study group was applied daily treatment of low level laser with a total of eight sessions of radiation, while in the control group extraction wounds were dressed with zinc oxide eugenol paste, which was changed every 48 hours up to the pain cessation. Measurement of pain intensity was done with a visual analogue scale (VAS 10 min prior to processing of extraction wounds and daily for the next eight days. Assessment of the effectiveness of low level laser on healing of extraction wounds was performed on the day eight of the treatment. Results. On the day five after beginning of the treatment of extraction wounds with alveolar osteitis in the patients of the study group a lower average value of pain as compared to the control group was registered. This difference was increased within the following days. Extraction wounds healing in the study group was more successful and faster than in the control group. Conclusion. This study suggested that the reduction of pain was more pronounced in the patients with alveolar osteitis whose extraction wounds were subjected to low level laser radiation in comparison to those in which extraction wounds were treated with zinc oxide eugenol paste.

    Full Text Available ABSTRACT Objective: To present the results of treatment of patients with cervical discopathy by anterior cervical approach, discectomy and placement of a PEEK interbody cage without anterior plate fixation. Methods: Retrospective, cross-sectional study from March 2013 to March 2015. Sixteen patients with radiculopathy or clinical signs of myelopathy were included; all patients underwent cervical surgery through anterior approach, discectomy, and placement of PEEK cages on three levels. Decompression levels were determined according to the correlation between preoperative radiological and clinical findings. Results: Sixteen patients predominantly male were included, with mean age of 50 years at the onset of the condition. Ten patients had involvement of C4-C5, C5-C6, C6-C7 levels, and six patients C3-C4, C4-C5 and C5-C6. Fourteen patients had cervicobrachialgia and two myelopathy. The preoperative visual analog scale average was 8/10 and the average postoperative value at 6 months was 3/10. At 6 months, there was no radiological evidence of recurrence. One patient had non-fatal complications. Conclusions: The treatment of cervical discopathy by anterior approach with interbody fusion with PEEK cage on three levels, with no plate fixation seemed to be safe and effective with better long-term results in terms of pain and myelopathy. The clinical results compare favorably with other similar series and, most importantly, the complications associated with anterior fixation plate are avoided.

    Full Text Available Masamichi Ishioka, Norio Yasui-Furukori, Norio Sugawara, Hanako Furukori, Shuhei Kudo, Kazuhiko Nakamura Department of Neuropsychiatry, Graduate School of Medicine, Hirosaki University, Hirosaki, Japan Objective: The strong association between psychiatric patients who receive antipsychotics and the incidence of venous thromboembolism (VTE is known. Although previous reports suggest that hyperprolactinemia often increases markers of activated coagulation, few studies have examined the direct relationship between the prolactin level elevated by antipsychotics and activated markers of activated coagulation.Method: The participants included 182 patients with schizophrenia (male =89, female =93 who received antipsychotic treatments for at least 3 months. Markers of VTE (D-dimer, fibrin/fibrinogen degradation products, and thrombin–antithrombin complex and serum prolactin concentrations were measured.Results: Prolactin levels were significantly correlated with the logarithmic transformation of the D-dimer (r=0.320, P=0.002 and fibrin/fibrinogen degradation product levels (r=0.236, P=0.026 but not of the thrombin–antithrombin complex level (r=0.117, ns among men. However, no correlations were found between the VTE markers and prolactin levels among women. These results were confirmed using multiple regression analyses that included demographic factors and antipsychotic dosages. Conclusion: The current study indicates that hyperprolactinemia is associated with an increase in markers of activated coagulation among men receiving antipsychotics. This finding clinically implies that monitoring and modulating prolactin levels among men are important to decrease the risk of VTE. Keywords: prolactin, antipsychotics, venous thromboembolism

    Rheumatoid arthritis (RA) is a chronic, inflammatory, and autoimmune disease that can cause permanent joint damage. In our study, we aim to analyze the change in calprotectin levels following the low-density exercise levels applied to the patients with RA. Twenty-eight patients with RA and 30 healthy controls were included in this study. To evaluate the activity of disease in RA, scores of disease activity that has increased (DAS-28) are figured. Calprotectin, nitric oxide (NO), white blood cell (WBC) count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and rheumatoid factor (RF) levels are tested as the laboratory evaluation. Calprotectin, NO, CRP, ESR, WBC, and RF levels were significantly higher in the patient group compared to the control group (p calprotectin, and DAS-28, CRP, NO, RF, and WBC (p calprotectin, DAS-28, NO, CRP, ESR, and RF levels (p calprotectin levels and other inflammatory parameters. At the same time, it shows that calprotectin which is a significant indicator of local inflammation can be used as a good identifier in following up exercise treatment.

    The interaction of lipoproteins with hepatitis C virus (HCV) has pathogenic and therapeutic implications. Our aim was to evaluate changes in the apolipoprotein profile of patients with chronic hepatitis C during and after successful cure with ledipasvir and sofosbuvir (LDV/SOF) with and without ribavirin (RBV). One hundred HCV genotype 1 patients who had achieved SVR-12 after treatment with 12 weeks of LDV/SOF ± RBV were selected from the ION-1 clinical trial. Frozen serum samples from baseline, end of treatment and week 4 of follow-up were used to assay apolipoproteins (apoAI, apoAII, apoB, apoCII, apoCIII, apoE) using the Multiplex platform to assess for changes in the apolipoprotein levels. At the end of treatment compared to baseline, a significant reduction in apoAII levels (-14.97 ± 63.44 μg/mL, P = 0.0067) and apoE levels (-4.38 ± 12.19 μg/mL, P < 0.001) was noted. These declines from baseline in apoAII (-16.59 ±66.15 μg/mL, P = 0.0075) and apoE (-2.66 ± 12.64 μg/mL, P = 0.015) persisted at 4 weeks of post-treatment follow-up. In multivariate analysis, treatment with LDV/SOF + RBV was independently associated with reduction in apoE (beta = 5.31 μg/mL, P = 0.002) (compared to RBV-free LDV/SOF) (P < 0.05). In contrast, apoCII levels overall increased from baseline to end of treatment (+2.74 ±11.76 μg/mL, P = 0.03) and persisted at 4 weeks of follow-up (+4.46 ± 12.81 μg/mL from baseline, P = 0.0005). Subgroup analysis revealed an increase in apoCII during treatment only in patients receiving LDV/SOF without RBV (+5.52 ± 11.92 μg/mL, P = 0.0007) but not in patients receiving LDV/SOF + RBV (P = 0.638). Treatment with LDV/SOF ± RBV is associated with a persistent reduction in the apolipoprotein AII and E after achieving cure. These data suggest that treatment with LDV/SOF ± RBV may be associated with alterations in serum apolipoproteins which could potentially impact viral eradication.

    Industry residues, phosphate fertilisers and wastewater as a source of irrigation have considerably increased levels of heavy metals in the soil, mainly cadmium (Cd(2+)). To test the effects of a calcium (Ca(2+)) treatment on Cd(2+) accumulation and plant tolerance to this heavy metal, plants of two citrus genotypes, Cleopatra mandarin (CM) and Carrizo citrange (CC), were watered with increasing concentrations of Cd(2+), and phytochelatin (PC) and glutathione (GSH) content were measured. Both genotypes were able to synthesise PCs in response to heavy metal intoxication, although CM seems to be a better Cd(2+) excluder than CC. However, data indicate that CC plants had a higher capacity for regenerating GSH than CM plants. In this context, the effects of Ca(2+) treatment on Cd(2+) accumulation, plant survival and PC, GSH and oxidised glutathione (GSSG) content were assessed. Data indicate that treatment with Ca(2+) had two positive effects on citrus physiology: it reduced Cd(+2) uptake into roots and also increased GSH content (even in the absence of Cd(2+)). Overall, the data indicate that although Cd(2+) exclusion is a powerful mechanism to avoid heavy metal build-up into photosynthetic organs, the capacity to maintain optimum GSH levels to feed PC biosynthesis could also be an important factor in stress tolerance.

    Nanostructure formation was explored for various carbon-based materials, such as diamond, carbon fiber, polyethylene terephthalate and poly (methyl methacrylate), which have different levels of crystallinity, ranging from perfect crystal to polymeric amorphous. After treatment of oxygen plasma glow discharge, the nanostructures on these carbon-based materials were found to evolve via preferential etching due to the co-deposition of metal elements sputtered from the metal cathode plate. Local islands or clusters formed by the metal co-deposition have a low etching rate compared to pristine regions on each material, resulting in anisotropic patterns on the carbon-based materials. This pattern formation mechanism was confirmed by covering the cathode or preventing the co-deposition of metallic sources with a polymeric material. Regardless of the level of crystallinity of the carbon-based materials, no patterns were observed on the surfaces covered with the polymeric material, and the surfaces were uniformly etched. It was found that the materials with low crystallinity had a high etching rate due to low carbon atom density, which thus easily formed high-aspect-ratio nanostructures for the same plasma treatment duration. - Highlight: • Reactive ion etching & metal deposition were occurred in oxygen plasma treatment. • High-aspect-ratio nanostructures can be fabricated on carbon-based materials. • Materials with low crystallinity easily formed high-aspect-ratio nanostructure. • Amount of etching inhibitors affects the pattern formation and configuration.

    DOE proposes to transport contact-handled LLMW from the Hanford Site to the Allied Technology Group (ATG) Mixed Waste Facility (MWF) in Richland, Washington, for non-thermal treatment and to return the treated waste to the Hanford Site for eventual land disposal. Over a 3-year period the waste would be staged to the ATG MWF, and treated waste would be returned to the Hanford Site. The ATG MWF would be located on an 18 hectare (ha) (45 acre [at]) ATG Site adjacent to ATG's licensed low-level waste processing facility at 2025 Battelle Boulevard. The ATG MWF is located approximately 0.8 kilometers (km) (0.5 miles [mi]) south of Horn Rapids Road and 1.6 km (1 mi) west of Stevens Drive. The property is located within the Horn Rapids triangle in northern Richland (Figure 2.1). The ATG MWF is to be located on the existing ATG Site, near the DOE Hanford Site, in an industrial area in the City of Richland. The effects of siting, construction, and overall operation of the MWF have been evaluated in a separate State Environmental Policy Act (SEPA) EIS (City of Richland 1998). The proposed action includes transporting the LLMW from the Hanford Site to the ATG Facility, non-thermal treatment of the LLMW at the ATG MWF, and transporting the waste from ATG back to the Hanford Site. Impacts fi-om waste treatment operations would be bounded by the ATG SEPA EIS, which included an evaluation of the impacts associated with operating the non-thermal portion of the MWF at maximum design capacity (8,500 metric tons per year) (City of Richland 1998). Up to 50 employees would be required for non-thermal treatment portion of the MWF. This includes 40 employees that would perform waste treatment operations and 10 support staff. Similar numbers were projected for the thermal treatment portion of the MWF (City of Richland 1998).

    Infantile Refsum disease (IRD) is one of the less severe of Zellweger spectrum disorders (ZSDs), a group of peroxisomal biogenesis disorders resulting from a generalized peroxisomal function impairment. Increased plasma levels of very long chain fatty acids (VLCFA) and phytanic acid are biomarkers used in IRD diagnosis. Furthermore, an increased plasma level of phytanic acid is known to be associated with neurologic damage. Treatment of IRD is symptomatic and multidisciplinary.The authors report a 3-year-old child, born from consanguineous parents, who presented with developmental delay, retinitis pigmentosa, sensorineural deafness and craniofacial dysmorphisms. While the relative level of plasma C26:0 was slightly increased, other VLCFA were normal. Thus, a detailed characterization of the phenotype was essential to point to a ZSD. Repeatedly increased levels of plasma VLCFA, along with phytanic acid and pristanic acid, deficient dihydroxyacetone phosphate acyltransferase activity in fibroblasts and identification of the homozygous pathogenic mutation c.2528G>A (p.Gly843Asp) in the PEX1 gene, confirmed this diagnosis. Nutritional advice and follow-up was proposed aiming phytanic acid dietary intake reduction. During dietary treatment, plasma levels of phytanic acid decreased to normal, and the patient's development evaluation showed slow progressive acquisition of new competences.This case report highlights the relevance of considering a ZSD in any child with developmental delay who manifests hearing and visual impairment and of performing a systematic biochemical investigation, when plasma VLCFA are mildly increased. During dietary intervention, a biochemical improvement was observed, and the long-term clinical effect of this approach needs to be evaluated.

    Lacosamide, a histone deacetylase (HDAC) inhibitor, has been approved for the treatment of epilepsy. Some HDAC inhibitors have been proven effective for the treatment of memory disorders. The present investigation was designed to evaluate the effect of lacosamide on memory and brain HDAC levels. The effect on memory was evaluated in animals with scopolamine-induced amnesia using the elevated plus maze, object recognition test, and radial arm maze. The levels of acetylcholinesterase and HDAC in the cerebral cortex were evaluated. Lacosamide at doses of 10 and 30mg/kg significantly reduced the transfer latency in the elevated plus maze. Lacosamide at a dose of 30mg/kg significantly increased the time spent with a familiar object in the object recognition test at the 24h interval and decreased the time spent in the baited arm. Moreover, at this dose, the number of errors in the radial arm maze at 3 and 24h intervals was minimized and a reduction in the level of HDAC1, but not acetylcholinesterase, was observed in the cerebral cortex. These effects of lacosamide are equivalent to those of piracetam at a dose of 300mg/kg. These results suggest that lacosamide at a 30mg/kg dose improves disrupted memory, possibly by inhibiting HDAC, and could be used to treat amnesic symptoms of Alzheimer's disease.

    A bioregenerative life support system (BLSS) is an artificial closed ecosystem for providing basic human life support for long-duration, far-distance space explorations such as lunar bases. In such a system, the circulation of gases is one of the main factor for realizing a higher closure degree. O2 produced by higher plants goes to humans, as well as microorganisms for the treatment of inedible plant biomass and human wastes; CO2 produced by the crew and microorganisms is provided for plant growth. During this process, an excessively high CO2 level will depress plant growth and may be harmful to human health; and if the CO2 level is too low, plant growth will also be affected. Thus, keeping the balance between CO2 and O2 levels is a crucial problem. In this study, a high-efficiency, controllable solid waste treatment unit is constructed, which adopts microbial fermentation of the mixture of inedible biomass and human wastes. CO2 production during the fermentation process is controlled by adjusting fermentation temperature, aeration rate, moisture, etc., so as to meet the CO2 requirement of plants

    The aim of this study was to evaluate the efficacy of the treatment with antipsychotic olanzapine in cocaine abuse methadone patients. The decrease or interruption of cocaine consume as well as the possible pharmacokinetic interaction between olanzapine and methadone were studied. Patients (n= 21) include in a methadone maintenance program (14 months), with DSM-IV criteria for opioid and cocaine dependence and without schizophrenic diagnostic, were treated with olanzapine 5 to 10 mg/day. The therapeutic outcomes were assessed by personal interviews, cocaine consumption, changes of consumption patrons (via of administration) and secondary effects to olanzapine. Withdrawal symptoms were measured by means of the abbreviate version of the scale of Gossop. Cocaine used was measured by urine analysis (enzymoimmnuoassay). The possible pharmacokinetic interaction between olanzapine and methadone was measured in plasma before and during the treatment in 15 patients. Olanzapine combined with methadone in cocaine abusers was well tolerated in an important proportion of patients. Moreover the consumption of cocaine was decreased or stopped in 53,2% of the patients. In addition, no withdrawal syndrome was observed in any patients. Furthermore the ratios of methadone plasma levels did not change in relation to the dose before and during the treatment, suggesting a lack of pharmacokinetic interaction between methadone and olanzapine. In conclusion the results of this preliminary study, led us to advance that olanzapine could be a useful treatment for cocaine abuse at least in patients in a Methadone Maintenance Program, with the advantage of not to induce any pharmacokinetic interaction with methadone.

    Highlights: • Nanofiltration can offer one of the approaches in optimizing membrane system. • Operation parameters especially the pressure affect nuclides’ removal efficiency. • Organic polyamide membrane shows radiation resistance. • A summary of DF and flux values can be taken as reference in designing the membrane system for LLRWs treatment. - Abstract: Membrane technology has been proved as an effective technology in the treatment of low level radioactive wastewaters (LLRWs). As ‘loose reverse osmosis’, nanofiltration can be integrated with RO and offers the high permeate flux at low pressure without obvious loss of decontamination efficiency. In the paper, three kinds of commercially available NF membrane materials were investigated by lab-scale experiment with respect to the nuclide rejection. The results demonstrate the efficient elimination. The membrane flux can be improved by the elevation of temperature and cross-flow velocity within the ranges of 20–30 °C and 0.4–1.0 m s{sup −1}. The radiation resistance test demonstrates no obvious loss of flux and nuclide rejection after a long term operation in the radioactive circumstance. A brief comparison of LLRWs treatment methods shows that NF can perform the pre-treatment of RO and optimize the entire membrane system with high flux and low pressure. In the paper, decontamination factor and flux values of the tested membranes at different operation condition are summarized as the reference for membrane selection and system design.

    This study aimed to evaluate the level of taurine in plasma, and its association with the severity of motor and non-motor symptoms (NMS) and chronic levodopa treatment in Parkinson's disease (PD). Plasma taurine level was measured in treated PD (tPD), untreated PD (ntPD) and control groups. Motor symptoms and NMS were assessed using the Unified Parkinson's Disease Rating Scale, the short form of the McGill Pain Questionnaire, the Hamilton Depression Scale, the Scale for Outcomes in Parkinson's disease for Autonomic Symptoms and the Pittsburgh Sleep Quality Index. Longtime exposure to levodopa was indicated by its approximate cumulative dosage. The plasma taurine levels of PD patients were decreased when compared with controls and negatively associated with motor severity but not NMS. Moreover, tPD patients exhibited lower levels of plasma taurine than ntPD patients. Interestingly, plasma taurine levels negatively correlated with cumulative levodopa dosage in tPD. After controlling for potential confounders, the association between taurine and levodopa remained significant. Our study supports that taurine may play important roles in the pathophysiology of PD and the disturbances caused by chronic levodopa administration.

Data on the clinical outcomes of infants born to mothers under phenobarbital treatment during pregnancy show that they are at risk of adverse events, such as sedation and abstinence syndrome. The aim of this study was to analyse the correlation between serum levels of phenobarbital and clinical features of neonates. Twenty-three infants born between 2001 and 2008 were studied. Maternal, neonatal and pharmacological variables were considered. Eleven infants displayed symptoms related to phenobarbital. Withdrawal syndrome was seen in seven infants and sedation syndrome was seen in four infants. One infant had severe cardiorespiratory depression at birth. None of the infants had severe neonatal abstinence syndrome. No statistically significant differences were found between symptomatic and asymptomatic infants. At birth, the mean serum level of phenobarbital of the 23 infants was 15.4 [standard deviation (SD) 6.2] μg/ml. A peak (16.1 μg/ml, SD 5.5) was seen on Day 3, followed by a gradual decrease to non-therapeutic levels (Phenobarbital levels were higher in symptomatic infants than asymptomatic infants, although the difference was not statistically significant. Serum levels of phenobarbital remained in the therapeutic range for both mothers and infants, and reduced gradually in infants. However, some infants displayed symptoms related to phenobarbital. As such, a clinical pharmacological surveillance protocol is necessary. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Cognitive impairment in hemodialysis patients is common, but the underlying pathogenesis remains unclear. Alzheimer's disease is the most common cause of dementia in the general elderly population. Histopathological hallmarks are, among others, senile plaques, which consist of amyloid-β (Aβ). To measure plasma levels of Aβ42 and Aβ40 during hemodialysis and to examine potential associations with cognitive performance in cognitively impaired hemodialysis patients. Plasma samples of 26 hemodialysis patients were collected shortly before, after 50% of dialysis time, and at the end of a dialysis session. Aβ42 and Aβ40 levels were measured by a high-sensitivity ELISA for human amyloid-β. Cognition was tested under standardized conditions using the Montreal Cognitive Assessment (MoCA) as proposed previously. Clearance rates of both peptides during one dialysis session were 22% and 35% for Aβ42 and Aβ40, respectively. Aβ42 but not Aβ40 baseline levels were significantly associated with MoCA test results (r = 0.654, p = 0.001). In cognitively impaired hemodialysis patients plasma Aβ42 levels were associated with cognitive performance and both Aβ42 and Aβ40 plasma levels could be effectively reduced by dialysis. By inducing peripheral Aβ sink, hemodialysis may be considered as an anti-amyloid treatment strategy.

    Three levels of sensorimotor control within the central nervous system (CNS) can be distinguished. During the neonatal stage, general movements and primitive reflexes are controlled at the spinal and brain stem levels. Analysis of the newborn's spontaneous general movements and the assessment of primitive reflexes is crucial in the screening and early recognition of a risk for abnormal development. Following the newborn period, the subcortical level of the CNS motor control emerges and matures mainly during the first year of life. This allows for basic trunk stabilization, a prerequisite for any phasic movement and for the locomotor function of the extremities. At the subcortical level, orofacial muscles and afferent information are automatically integrated within postural-locomotor patterns. Finally, the cortical (the highest) level of motor control increasingly becomes activated. Cortical control is important for the individual qualities and characteristics of movement. It also allows for isolated segmental movement and relaxation. A child with impaired cortical motor control may be diagnosed with developmental dyspraxia or developmental coordination disorder. Human ontogenetic models, i.e., developmental motor patterns, can be used in both the diagnosis and treatment of locomotor system dysfunction. Copyright © 2013 Elsevier Ltd. All rights reserved.

  3. Effect of β-alanine treatment on mitochondrial taurine level and 5-taurinomethyluridine content

    Science.gov (United States)

    2010-01-01

    Background The β-amino acid, taurine, is a nutritional requirement in some species. In these species, the depletion of intracellular stores of taurine leads to the development of severe organ dysfunction. The basis underlying these defects is poorly understood, although there is some suggestion that oxidative stress may contribute to the abnormalities. Recent studies indicate that taurine is required for normal mitochondrial protein synthesis and normal electron transport chain activity; it is known that defects in these events can lead to severe mitochondrial oxidative stress. The present study examines the effect of taurine deficiency on the first step of mitochondrial protein synthesis regulation by taurine, namely, the formation of taurinomethyluridine containing tRNA. Methods Isolated rat cardiomyocytes were rendered taurine deficient by incubation with medium containing the taurine transport inhibitor, β-alanine. The time course of cellular and mitochondrial taurine depletion was measured. The primer extension method was employed to evaluate the effect of β-alanine treatment on taurinomethyluridine content of tRNALeu. The protein levels of ND6 were also determined by Western blot analysis. Results β-alanine caused a time-dependent decrease in cellular taurine content, which were reduced in half after 48 hrs of incubation. The amount of taurine in the mitochondria was considerably less than that in the cytosol and was unaffected by β-alanine treatment. Approximately 70% of the tRNALeu in the untreated cell lacked taurinomethyluridine and these levels were unchanged following β-alanine treatment. Protein content of ND6, however, was significantly reduced after 48 hours incubation with β-alanine. Conclusions The taurine levels of the cytosol and the mitochondria are not directly coupled. The β-alanine-mediated reduction in taurine levels is too small to affect taurinomethyluridine levels. Nonetheless, it interferes with mitochondrial protein synthesis

    Several studies in human and animals show the clinical effectiveness of low level laser therapy (LLLT) in reducing some types of pain, treating inflammation and wound healing. However, more scientific evidence is required to prove the effectiveness of LLLT since many aspects of the cellular and molecular mechanisms triggered by irradiation of injured tissue with laser remain unknown. Here, we present a methodology that can be used to evaluate the effect of different LLLT irradiation parameters on the treatment of muscle inflammation on animals, through the quantification of four cytokines (TNF-α, IL-1β, IL-2 and IL-6) in systemic blood and histological analysis of muscle tissue. We have used this methodology to assess the effect of LLLT parameters (wavelength, dose, power and type of illumination) in the treatment of inflammation induced in the gastrocnemius muscle of Wistar rats. Results obtained for laser dose evaluation with continuous illumination are presented.

    Full Text Available Decubitus ulcers in the oral mucosa tend to be very painful causing discomforting sensation in patients in speaking and eating. Low energy lasers can provide an alternative method for the treatment of these ulcers.The aim of the present paper was to assess clinically the healing effect of low level laser irradiation on oral mucosa decubitus ulcers.Material and methods: A total of 90 patients with decubitus ulcers were treated in the present study; they were randomly assigned to three groups: group I included 30 patients treated with low level laser (LLL irradiation (wavelength of irradiation 658 nm; group II - 30 patients treated with laser irradiation of 904 nm; and group III (controls - 30 patients who received a standard conventional treatment with "granofurin" and "solcoseryl".The treatment sessions in all three groups were administered once daily. The patients in groups I and II were irradiated with focused irradiation at an angle from a distance using a conically shaped light probe 3 mm in diameter. The irradiated area was 0.5 cm2. The light was focused on the oral mucosa ulcer and the surrounding inflamed mucosa at a distance of 0.5 to 1 cm. Diode lasers were used in the study. The dosage of irradiation was 1.2 J/cm2.Results and discussion: The treatment effect was evaluated by changes in the studied parameters: pain intensity, erythema, and epithelialization. They were assessed at baseline, and at days 1, 3 and 5. Conclusions: LLLT administered with the proposed methodology manages pain rapidly and accelerates the process of epithelialization of decubitus ulcers in the soft tissues of the mouth.

    Full Text Available BACKGROUND: The aging process and its associated morphophysiological changes trigger a reduction in the regenerative ability of the satellite cells, a reduction of vascular tissue and an increase in the production of fibroblasts, developing a cellular environment unfavorable for muscle regeneration. OBJECTIVE: The aim of this study was to evaluate the effect of low-level laser therapy on the muscle regeneration of old experimental rat models after contusion. METHOD: A total of 25 old rats,18 months old, were divided into three groups: control group (CT without treatment; injury group (IN with muscle contusion and without treatment and laser group (LA with contusion and low-level laser therapy, 830 nm, 30 mW e 4 J/cm². The no invasive contusion was induced in the Tibialis Anterior muscle and the samples were collected after 7 and 21 treatment sessions. The muscle was evaluated by Light Microscopy and Immunoblotting. RESULTS: After 21 days of treatment there was a significant reduction in the areas of inflammation/regeneration of the LA 21 group compared to IN 21 group. The cross-sectional area of the fibers in regeneration was not statistically different between the groups. Molecular analysis showed that the content of MyoD was statistically reduced in the IN 21 group compared to the CT group. The Myogenin content was increased in the IN 21 group compared to the CT group. Ultimately, the content of TGF-β1 on the IN 21 group was higher when compared to the CT group. CONCLUSION: Considering the parameters used, the laser therapy demonstrated to be effective for muscle regeneration in old rats, however only through its anti-inflammatory effect.

    Full Text Available Nilüfer Dönmezdil, Mehmet Uğur Çevik, Hasan Hüseyin Özdemir, Muhterem Taşin Department of Neurology, Dicle University, Diyarbakır, Turkey Purpose: There are many studies dedicated to researching the etiopathogenesis of epilepsy. In such research, oxidative and antioxidant indicators of etiopathogenesis have also been examined under the scope. Drawing on a group of patients with epilepsy who were receiving no treatment, we have tried to evaluate whether or not an increase in oxidative indicators is linked directly with the disorder, independent of epileptic medicaments.Methods: Thirty people in good health and 30 newly diagnosed with epilepsy and who received ambulatory treatment in the polyclinic of the Neurology Department took part in the study. The tests relating to serum malondialdehyde (MDA levels and paraoxonase 1 (PON1 activity were carried out in the biochemistry laboratory.Results: Even though the levels of MDA in the patient group (14.34±3.59 nmol/mL were found to be high compared to those of the control group, which consisted of people in good health (13.53±3.56 nmol/mL, there was no statistically significant difference. PON1 activity in the serum taken from people in the patient group (0.65±0.17 was lower in comparison to that observed in the serum of the control group (0.71±0.17 U/L. Nonetheless, it was not so low as to have significance from a statistical point of view.Conclusion: We conclude that such a high level of oxidative parameters should have been related to the disease and that statistically significant findings that emerged in some other studies could have been related to an antiepileptic treatment.

    Black-grass is a common grass weed, widely spread in Northern Europe and also in Belgium. For ages, it has been an increasing problem in industrial crops, especially winter cereals. Therefore, farmers started to spray herbicide intensively and soon cases of failure occurred for different molecules and different modes of action. Black-grass populations have been tested in greenhouses to assess the influence of an herbicide treatment as to the resistance level regarding three different herbicides: chlortoluron, fenoxaprop-P and mesosulfuron+iodosulfuron. Black-grass seeds were collected in field trials in six locations in Belgium, on individuals which have survived the herbicide treatment. Each population comes from trial plots, measuring 2 meters wide by 5 meters long and characterized by a single or a combination of products. Herbicides sprayed were isoproturon, flufenacet+diflufenican, ACCase inhibitors and ALS inhibitors. Seeds were also collected in the untreated plots. The population present in these last ones corresponds to the former population, before the herbicide selection pressure was applied. In the glasshouse assay, this population was used as the standard population to compare with other populations issued from the same field. The 'R' rating system was set up with this population to assess the evolution of resistance level, year in, year out. Rothamsted and Peldon populations were also included as cross-reference. Each field population presented different behaviours towards herbicide applied in greenhouses and some cases of resistance can be highlighted. Generally, a reduction of treatment efficiency between field and greenhouse results was clearly visible for the whole of studied active ingredients. Indeed, a distribution shift of the populations towards higher resistance classes could be observed. This is particularly remarkable for active ingredients sharing the same mode of action. For example, it has been found that populations already sprayed

    Hyperoxia exposure in mice leads to cardiac hypertrophy and voltage-gated potassium (Kv) channel remodeling. Because redox balance of pyridine nucleotides affects Kv function and hyperoxia alters cellular redox potential, we hypothesized that hyperoxia exposure leads to cardiac ion channel disturbances and redox changes resulting in arrhythmias. In the present study, we investigated the electrical changes and redox abnormalities caused by 72 h hyperoxia treatment in mice. Cardiac repolarization changes were assessed by acquiring electrocardiogram (ECG) and cardiac action potentials (AP). Biochemical assays were employed to identify the pyridine nucleotide changes, Kv1.5 expression and myocardial injury. Hyperoxia treatment caused marked bradycardia, arrhythmia and significantly prolonged (ms) the, RR (186.2 ± 10.7 vs. 146.4 ± 6.2), PR (46.8 ± 3.1 vs. 39.3 ± 1.6), QRS (10.8 ± 0.6 vs. 8.5 ± 0.2), QTc (57.1 ± 3.5 vs. 40 ± 1.4) and JT (13.4 ± 2.1 vs. 7.0 ± 0.5) intervals, when compared with normoxia group. Hyperoxia treatment also induced significant increase in cardiac action potential duration (APD) (ex-APD{sub 90}; 73.8 ± 9.5 vs. 50.9 ± 3.1 ms) and elevated levels of serum markers of myocardial injury; cardiac troponin I (TnI) and lactate dehydrogenase (LDH). Hyperoxia exposure altered cardiac levels of mRNA/protein expression of; Kv1.5, Kvβ subunits and SiRT1, and increased ratios of reduced pyridine nucleotides (NADH/NAD and NADPH/NADP). Inhibition of SiRT1 in H9C2 cells using Splitomicin resulted in decreased SiRT1 and Kv1.5 expression, suggesting that SiRT1 may mediate Kv1.5 downregulation. In conclusion, the cardiotoxic effects of hyperoxia exposure involve ion channel disturbances and redox changes resulting in arrhythmias. - Highlights: • Hyperoxia treatment leads to arrhythmia with prolonged QTc and action potential duration. • Hyperoxia treatment alters cardiac pyridine nucleotide [NAD(P)H/NAD(P)] levels. • SiRT1 and Kv1.5 are co

    High-level radioactive wastes generated from nuclear fuel reprocessing require treatment for effective long-term storage. Heating by microwave energy is explored in processing of two possible waste forms: (1) drying of a pelleted form of calcined waste; and (2) vitrification of calcined waste. It is shown that residence times for these processes can be greatly reduced when using microwave energy rather than conventional heating sources, without affecting product properties. Compounds in the waste and in the glass frit additives couple very well with the 2.45 GHz microwave field so that no special microwave absorbers are necessary.

    Full Text Available Abstract Background When treating schizophrenia, improving patients' productivity level is a major goal considering schizophrenia is a leading cause of functional disability. Productivity level has been identified as the most preferred treatment outcome by patients with schizophrenia. However, little has been done to systematically investigate productivity levels in schizophrenia. We set out to better understand the change in productivity level among chronically ill patients with schizophrenia treated with olanzapine compared with other antipsychotic medications. We also assessed the links between productivity level and other clinical outcomes. Methods This post hoc analysis used data from 6 randomized, double-blind clinical trials of patients with schizophrenia or schizoaffective disorder, with each trial being of approximately 6 months duration. Change in productivity level was compared between olanzapine-treated patients (HGBG, n = 172; HGHJ, n = 277; HGJB, n = 171; HGLB, n = 281; HGGN, n = 159; HGDH, n = 131 and patients treated with other antipsychotic medications (separately vs. haloperidol [HGGN, n = 97; HGDH, n = 132], risperidone [HGBG, n = 167; HGGN, n = 158], quetiapine [HGJB, n = 175], ziprasidone [HGHJ, n = 271] and aripiprazole [HGLB, n = 285]. Productivity was defined as functional activities/work including working for pay, studying, housekeeping and volunteer work. Productivity level in the prior 3 months was assessed on a 5-point scale ranging from no useful functioning to functional activity/work 75% to 100% of the time. Results Chronically ill patients treated with olanzapine (OLZ experienced significantly greater improvement in productivity when compared to patients treated with risperidone (RISP (OLZ = 0.22 ± 1.19, RISP = -0.03 ± 1.17, p = 0.033 or ziprasidone (ZIP (OLZ = 0.50 ± 1.38, ZIP = 0.25 ± 1.27, p = 0.026, but did not significantly differ from the quetiapine, aripiprazole or haloperidol treatment groups.

    Despite recent general improvements in health care, significant disparities persist in the cardiovascular care of women and racial/ethnic minorities. This is true even when income, education level, and site of care are taken into consideration. Possible explanations for these disparities include socioeconomic considerations, elements of discrimination and racism that affect socioeconomic status, and access to adequate medical care. Coronary revascularization has become the accepted and recommended treatment for myocardial infarction(MI) today and is one of the most common major medical interventions in the United States, with more than 1 million procedures each year. This review discusses recent data on disparities in co-morbidities and presentation symptoms, care and access to medical resources, and outcomes in revascularization as treatment for acute coronary syndrome, looking especially at women and minority populations in the United States. The data show that revascularization is used less in both female and minority patients. We summarize recent data on disparities in co-morbidities and presentation symptoms related to MI; access to care, medical resources, and treatments; and outcomes in women, blacks, and Hispanics. The picture is complicated among the last group by the many Hispanic/Latino subgroups in the United States. Some differences in outcomes are partially explained by presentation symptoms and co-morbidities and external conditions such as local hospital capacity. Of particular note is the striking differential in both presentation co-morbidities and mortality rates seen in women, compared to men, especially in women ≤ 55 years of age. Surveillance data on other groups in the United States such as American Indians/Alaska Natives and the many Asian subpopulations show disparities in risk factors and co-morbidities, but revascularization as treatment for MI in these populations has not been adequately studied. Significant research is required to

    An attempt is made to identify the main sources of low-level radioactive wastes that are generated in the United States. To place the waste problem in perspective, rough estimates are given of the annual amounts of each generic type of waste that is generated. Most of the wet solid wastes arise from the cleanup of gaseous and liquid radioactive streams prior to discharge or recycle. The treatment of the process streams and the secondary wet solid wastes thus generated is described for each type of government or fuel cycle installation. Similarly, the institutional wet wastes are also described. The dry wastes from all sources have smilar physical and chemical characteristics in that they can be classified as compactible, noncompactible, combustible, noncombustible, or combinations thereof. The various treatment options for concentrated or solid wet wastes and for dry wastes are discussed. Among the dry-waste treatment methods are compaction, baling, and incineration, as well as chopping, cutting, and shredding. Organic materials can usually be incinerated or, in some cases, biodegraded. The filter sludges, spent resins, incinerator ashes, and concentrated liquids are usually solidified in cement, urea-formaldehyde, or unsaturated polyester resins prior to burial. Asphalt has not yet been used as a solidificaton agent in the United States, but it probably will be used in the near future. The treatment of radioactive medical and bioresearch wastes is described, but the waste from radiochenmical, pharmaceutical, and other industries is not well defined at the present time. Recovery of waste metals and treatment of hazardous contaminated wastes are discussed briefly. Some areas appearing to need more research, development, and demonstration are specifically pointed out.

    Patulin is a mycotoxin produced primarily by Penicillium expansum, a mold responsible for rot in apples and other fruits. The growth of this fungus and the production of patulin are common in fruit that has been damaged. However, patulin can be detected in visibly sound fruit. The purpose of this project was to determine how apple quality, storage, and washing treatments affect patulin levels in apple cider. Patulin was not detected in cider pressed from fresh tree-picked apples (seven cultivars) but was found at levels of 40.2 to 374 microg/liter in cider pressed from four cultivars of fresh ground-harvested (dropped) apples. Patulin was not detected in cider pressed from culled tree-picked apples stored for 4 to 6 weeks at 0 to 2 degrees C but was found at levels of 0.97 to 64.0 microg/liter in cider pressed from unculled fruit stored under the same conditions. Cider from controlled-atmosphere-stored apples that were culled before pressing contained 0 to 15.1 microg of patulin per liter, while cider made from unculled fruit contained 59.9 to 120.5 microg of patulin per liter. The washing of ground-harvested apples before pressing reduced patulin levels in cider by 10 to 100%, depending on the initial patulin levels and the type of wash solution used. These results indicate that patulin is a good indicator of the quality of the apples used to manufacture cider. The avoidance of ground-harvested apples and the careful culling of apples before pressing are good methods for reducing patulin levels in cider.

    Full Text Available The study aims to investigate if low-level laser therapy (LLLT combined with eccentric exercises could more effectively treat patellar tendinopathy than LLLT alone and eccentric exercises alone. Twenty-one patients with patellar tendinopathy were randomized to three groups: laser alone, exercise alone, or laser plus exercise, with seven in each group. Laser irradiations were administered at the inferior pole of the patella and the two acupoints of Extra 36 (Xiyan with the intensity of 1592 mW/cm2. Eccentric training program consisted of three sets of 15 repetitions of unilateral squat on level ground. All patients received six treatments per week for four weeks. Knee pain and function and quadriceps muscle strength and endurance were evaluated at baseline and the end of treatment. After the 4-week intervention, all groups showed significant improvements in all the outcomes (P<0.01. The laser + exercise group had significantly greater improvements in all the outcomes than the other two groups (P<0.05, except nonsignificant difference in pain relief between the laser + exercise group and the laser group. In conclusion, LLLT combined with eccentric exercises is superior to LLLT alone and eccentric exercises alone to reduce pain and improve function in patients with patellar tendinopathy.

    Dentin hypersensitivity is one of the most common complications that affect patients after periodontal therapy. Recently low level laser therapy has been introduced as a new treatment modality and has produced beneficial results. The purpose of this study is to evaluate the effect of low level laser therapy toothbrushes in reduction of dentin hypersensitivity. In this pilot interventional controlled clinical trial, 40 patients suffering from dentin hypersensitivity were selected using simple randomization. Half of the patients were given laser toothbrushes and the other half was given non-laser sensodyne toothbrushes. Primary dentin hypersensitivity was recorded by visual analogue scale (VAS) score and ice spray. Then dentin hypersensitivity was measured right after the treatment as well az in the intervals of 1 month and 2 months after initiation of the study. Data were compared using Statistical Package for the Social Sciences (SPSS) software and Analysis of variance (ANOVA) paired T test. The results of this study showed that there was a significant difference in each of the two kinds of tooth brushes separately for all time intervals (P sensodyne and laser tooth brushes improve dentin hypersensitivity, although the laser toothbrush led to better results in short.

    The purpose of this study was to determine the presence of formocresol in the plasma of children undergoing oral rehabilitation involving pulp therapy under general anesthesia. Thirty 2- to 6-year-old preschool children were enrolled in the study. Preoperative, intra-operative, and postoperative peripheral venous samples were collected from each child. All samples were analyzed for formaldehyde and cresol levels using gas chromatography with mass spectrometry detection. Eighty-five pulpotomies were performed ranging from 1 to 5 per child. Three hundred twelve blood samples were collected. Analysis revealed that formaldehyde was undetectable above baseline plasma concentration and cresol was undetectable in all samples. Benzyl alcohol (a byproduct of cresol metabolism) was present in all samples except the baseline preoperative samples. Benzyl alcohol concentrations ranged from 0 to 1 mg/ml. Formaldehyde was undetectable above baseline plasma concentration, and cresol was undetectable in subjects receiving pulpotomy treatment under general anesthesia. Benzyl alcohol was detected in the plasma of all subjects receiving pulpotomy treatment. The levels present were far below the Food and Drug Administration's recommended daily allowance. It is unlikely that formocresol, when used in the doses typically employed for a vital pulpotomy procedure, poses any risk to children.

    Full Text Available The stroke is a socially significant disease that is characterized with high levels of morbidity and mortality, causing severe disability worldwide. It is the second most significant cause of death among the people in the western world, falling back only to the heart diseases and preceding the cancer, as it causes 10% of the mortal cases in the world. Since 2009 the Bulgarian association of neurosonology and cerebral hemodynamics(BANCH organizes different initiatives of training doctors to conduct a thrombolytic treatment to acute ischemic stroke(AIS. The intravenous thrombolysis has not been established as a leading differential treatment of AIS in Bulgaria, and the thrombolytic therapy is still not well developed in Bulgaria.The suport of national and local institutions is crucial for insuring and guarantee for a proper stroke treatment. Efforts are necessary for adequate financing of the health facilities, as well as professional preparation of the human resource, and training the population via creating an integrated national strategy for its application and control, which can underlie as a state politics in healthcare at optimal usage of public-private partnership.

    Full Text Available 1.1 billion People worldwide do not have access to safe drinking water and therefore are exposed to a high risk for diarrhoeal diseases. As a consequence, about 6,000 children die each day of dehydration due to diarrhoea. Adequate water treatment methods and safe storage of drinking water, combined with hygiene promotion, are required to prevent the population without access to safe drinking water from illness and death. Solar water disinfection (SODIS is a new water treatment to be applied at household level with a great potential to reduce diarrhoea incidence of users. The method is very simple and the only resources required for its application are transparent PET plastic bottles (or glass bottles and sufficient sunlight: microbiologically contaminated water is filled into the bottles and exposed to the full sunlight for 6 hours. During solar exposure, the diarrhoea causing pathogens are killed by the UV-A radiation of the sunlight. At present, SODIS is used by about 2 Million users in more than 20 countries of the South. Diarrhoea incidence of users significantly has been reduced by 30 to 70 %. A careful and long-term community education process that involves creating awareness on the importance of treating drinking water and initiates behaviour change is required to establish the sustainable practice of SODIS at community level. In Madagascar, more than 160 children younger than 5 years die each day from malaria, diarrhoea and acute respiratory illnesses. The application of household water treatment methods such as SODIS significantly could contribute to improve their health.

    Conclusions: A significant proportion of patients with advanced carcinoma of the prostate have flare in SAP le-vels soon after initiating the treatment. We confirm that the flare activity in SAP levels is a negative prognostic indicator and it is possible to identify early treatment fail-ures by frequent measurements of SAP levels during first 6 weeks of commencing the therapy. The significance of SAP fare and androgen resistance is discussed.

  3. Evaluation of Serum Cytokines Levels and the Role of Cannabidiol Treatment in Animal Model of Asthma

    Full Text Available Asthma represents a public health problem and traditionally is classified as an atopic disease, where the allergen can induce clinical airway inflammation, bronchial hyperresponsiveness, and reversible obstruction of airways. Studies have demonstrated the presence of T-helper 2 lymphocytes in the lung of patients with asthma. These cells are involved in cytokine production that regulates immunoglobulin synthesis. Recognizing that T cell interaction with antigens/allergens is key to the development of inflammatory diseases, the aim of this study is to evaluate the anti-inflammatory potential of cannabidiol (CBD in this setting. Asthma was induced in 8-week-old Wistar rats by ovalbumin (OVA. In the last 2 days of OVA challenge animals received CBD (5 mg/kg, i.p. and were killed 24 hours after. The levels of IL-4, IL-5, IL-13, IL-6, IL-10, and TNF-α were determinate in the serum. CBD treatment was able to decrease the serum levels of all analyzed cytokines except for IL-10 levels. CBD seems to be a potential new drug to modulate inflammatory response in asthma.

    Black cohosh (Actaea racemosa) serves as the host plant for the Appalachian azure butterfly, Celastrina neglectamajor. Overharvesting of Black cohosh for the dietary supplement industry may result in its extirpation, and may also cause the elimination of the dependent butterfly. One way to increase or maintain the number of host plants in forested environments would be to reduce the number harvested, for example by increasing the levels of the desired metabolites in Black cohosh rhizomes. The secondary metabolites actein and deoxyactein are triterpene glycosides and are among the compounds associated with the putative activity of Black cohosh extracts. Acetein and deoxyacetein are used to standardize Black cohosh supplements. To gain an understanding of mechanisms that may control actein and deoxyactein accumulation, Black cohosh rhizomes were treated with exogenous salicylic acid, jasmonic acid, or ethylene, or were mechanically wounded. Salicylic acid treatment significantly increased the levels of actein and deoxyactein in the rhizome of Black cohosh, suggesting that the synthesis of triterpene glycosides is controlled in part by salicylic acid. Using salicylic acid or related chemicals to increase the levels of actein and deoxyactein in rhizomes may help supply the supplement industry and, simultaneously, help conserve Black cohosh and species dependent upon it.

    Full Text Available In this experiment, raw milk and commercially available full-cream UHT milk, semi-skimmed UHT milk, skimmed UHT milk, full-cream pasteurized milk, semi-skimmed pasteurized milk and infant formulas for babies between 6 and 12 months of age were analyzed by RIA, with a method using an antibody directed against human leptin and human leptin as reference standard. Raw milk and full-cream UHT milk did not differ for human-like leptin. Leptin content of full-cream pasteurized milk was not different to that of full-cream UHT milk, but it was 14% lower (p < 0.05 than that observed in raw milk. Human-like leptin level of semi-skimmed UHT milk was not different to that of semi-skimmed pasteurized milk, but it was 30% lower (p < 0.0001 than those of full-cream UHT and full-cream pasteurized milks. In skimmed UHT milk, leptin was 40% lower (p < 0.0001 than in full-cream UHT milk. Leptin was correlated (p < 0.001 with lipid content. Leptin level of infant formulas was not different to that of skimmed milks. Results suggest that the heat treatment (pasteurization or UHT is not a modifier of human-like leptin content of edible commercial bovine milks, whereas the skimming process significantly reduces milk leptin level.

    Full Text Available OBJECTIVE: The objective of this study was to compare the pain levels on opposite sides of the maxilla at needle insertion during delivery of local anesthetic solution and tooth preparation for both conventional and anterior middle superior alveolar (AMSA technique with the Wand computer-controlled local anesthesia application. MATERIAL AND METHODS: Pain scores of 16 patients were evaluated with a 5-point verbal rating scale (VRS and data were analyzed nonparametrically. Pain differences at needle insertion, during delivery of local anesthetic, and at tooth preparation, for conventional versus the Wand technique, were analyzed using the Mann-Whitney U test (p=0.01. RESULTS: The Wand technique had a lower pain level compared to conventional injection for needle insertion (p0.05. CONCLUSIONS: The AMSA technique using the Wand is recommended for prosthodontic treatment because it reduces pain during needle insertion and during delivery of local anaesthetic. However, these two techniques have the same pain levels for tooth preparation.

    In the present study, we examined the possible effect of chronic treatment with glucocorticoids on the morphology of the rat brain and levels of endogenous agmatine and arginine decarboxylase (ADC) protein, the enzyme essential for agmatine synthesis. Seven-day treatment with dexamethasone, at a dose (10 and 50 mug/kg/day) associated to stress effects contributed by glucocorticoids, did not result in obvious morphologic changes in the medial prefrontal cortex and hippocampus, as measured by immunocytochemical staining with beta-tubulin III. However, 21-day treatment (50 mug/kg/day) produced noticeable structural changes such as the diminution and disarrangement of dendrites and neurons in these areas. Simultaneous treatment with agmatine (50 mg/kg/day) prevented these morphological changes. Further measurement with HPLC showed that endogenous agmatine levels in the prefrontal cortex and hippocampus were significantly increased after 7-day treatments with dexamethasone in a dose-dependent manner. On the contrary, 21-day treatment with glucocorticoids robustly reduced agmatine levels in these regions. The treatment-caused biphasic alterations of endogenous agmatine levels were also seen in the striatum and hypothalamus. Interestingly, treatment with glucocorticoids resulted in a similar change of ADC protein levels in most brain areas to endogenous agmatine levels: an increase after 7-day treatment versus a reduction after 21-day treatment. These results demonstrated that agmatine has neuroprotective effects against structural alterations caused by glucocorticoids in vivo. The parallel alterations in the endogenous agmatine levels and ADC expression in the brain after treatment with glucocorticoids indicate the possible regulatory effect of these stress hormones on the synthesis and metabolism of agmatine in vivo.

    2016-12-01

    Quantum mechanical treatment of a light wave that propagates through an absorptive medium is presented. Unlike a phenomenological beam-splitter model conventionally employed to describe a traveling light in a lossy medium, the time evolution of the field operator is derived using the Heisenberg equation with the Hamiltonian for a physical system, where the light wave interacts with an ensemble of two-level systems in a medium. Using the obtained time-evolved field operators, the mean values and variances of the light amplitude and the photon number are evaluated. The results are in agreement with those obtained in the beam-splitter model, giving a logical theoretical basis for the phenomenological beam-splitter model.

    2016-09-01

    Natalizumab (NTZ) is an effective therapy for multiple sclerosis (MS). A common concern related to NTZ therapy is the risk of developing progressive multifocal leukoencephalopathy (PML). A patient that after seven years on NTZ therapy, testing on every 3 months repeated evaluations negative for anti-JCV status became positive (>3 units) 4 weeks after receiving influenza vaccine. Despite continuous therapy on NTZ for additional 2 years her anti-JCV index progressively declined to a level 0.6 units Our case raises the consideration to include vaccination as a factor that can affect JCV index and should be tallied during NTZ treatment mitigation.

    The purpose of this document is to provide the overall planning framework for the role of simulation in the integration/optimization of treatment process trains for the High Level Waste (HLW) Program at Idaho National Engineering and Environmental Laboratory (INELL). This project involves a TTP (Technical Task Plan ID77WT31, Subtask C) with Savannah River Site (SRS) to jointly develop a simulation tool set that can support flowsheet optimization for HLW treatment trains at INEEL. Despite the commonality between the simulation efforts at SRS and INEEL, the individual work scopes of the two sites are different – that of the INEEL is broader. This document concerns only the scope of the INEEL effort, and it describes the boundaries of several scope-related planning areas for this project INEEL: 1) the objective of the project – the needs (drivers) the simulation efforts are attempting to satisfy, the role simulation results will play in managerial decision making, and the type of issues to be investigated; 2) constraints – higher-level budget forecasts and schedules, legal commitments, customer directives, and other similar forces that a priori define boundary elements; 3) the process domain – the set of chemical and physical operations to be modeled; 4) the model’s life cycle – the phases of the waste treatment’s life cycle that will utilize simulation, i.e., process configuration, design, and/or operations; 5) the types of models involved in the integrated simulation tool set – discrete vs. continuous, deterministic vs. stochastic, etc.; and 6) and targeted users – the downstream activities that may potentially use the simulation results. This document closes with a description of the budget, schedule, and task inter-relationships that result from the determined scope. This document is the cornerstone of the planning process, and many of the software requirements flow directly from the decisions discussed in this document.

    The potential for Zika virus (ZIKV) transfusion-transmission (TT) has been demonstrated in French Polynesia and Brazil. Pathogen inactivation (PI) of blood products is a proactive strategy to inactivate TT pathogens including arboviruses. Inactivation of West Nile, dengue, Zika, and chikungunya viruses was previously demonstrated by photochemical treatment with amotosalen and ultraviolet A (UVA) illumination. In this study, we evaluated ZIKV inactivation in red blood cell (RBC) components by a chemical approach that uses amustaline (S-303) and glutathione (GSH). RBC components were spiked with a high titer of ZIKV. Viral titers (infectivity) and ZIKV RNA loads (reverse transcription-polymerase chain reaction) were measured in spiked RBCs before and after S-303 and GSH treatment and confirmed using repetitive passages in cell culture. A mock-treated arm validated the approach by demonstrating stability of the virus (infectivity and RNA load) during the process. The mean ZIKV infectivity titer and RNA load in RBCs were 5.99 ± 0.2 log 50% tissue culture infectious dose (TCID50 )/mL and 7.75 ± 0.16 log genomic equivalents/mL before inactivation. No infectivity was detected immediately after S-303 and GSH treatment and after five serial passages in cell culture. Complete ZIKV inactivation of more than 5.99 log TCID50 /mL in RBCs was achieved using S-303 and GSH at levels higher than those found in asymptomatic ZIKV-infected blood donors. Therefore, the S-303 and GSH PI system is promising for mitigating the risk of ZIKV TT. © 2016 The Authors Transfusion published by Wiley Periodicals, Inc. on behalf of AABB.

    Full Text Available Diabetic foot ulcers as one of the most common complications of diabetes mellitus are defined as nonhealing or long-lasting chronic skin ulcers in diabetic patients. Multidisciplinary care for the diabetic foot is common, but treatment results are often unsatisfactory. Low level laser therapy (LLLT on wound areas as well as on acupuncture points, as a noninvasive, pain-free method with minor side effects, has been considered as a possible treatment option for the diabetic foot syndrome. A systematic literature review identified 1764 articles on this topic. Finally, we adopted 22 eligible references; 8 of them were cell studies, 6 were animal studies, and 8 were clinical trials. Cell studies and animal studies gave evidence of cellular migration, viability, and proliferation of fibroblast cells, quicker reepithelization and reformed connective tissue, enhancement of microcirculation, and anti-inflammatory effects by inhibition of prostaglandine, interleukin, and cytokine as well as direct antibacterial effects by induction of reactive oxygen species (ROS. The transferral of these data into clinical medicine is under debate. The majority of clinical studies show a potential benefit of LLLT in wound healing of diabetic ulcers. But there are a lot of aspects in these studies limiting final evidence about the actual output of this kind of treatment method. In summary, all studies give enough evidence to continue research on laser therapy for diabetic ulcers, but clinical trials using human models do not provide sufficient evidence to establish the usefulness of LLLT as an effective tool in wound care regimes at present. Further well designed research trials are required to determine the true value of LLLT in routine wound care.

    Percutaneous vertebroplasty (PVP) is a minimally invasive treatment for symptomatic vertebral compression fractures (VCFs). The aim of this study was to assess the effectiveness, complications and progress of results of PVP optimized in terms of technique, costs, time and strategic protocol after 3 years of procedures performed under fluoroscopic guidance alone. We treated 250 VCFs in 120 consecutive patients after assessing clinical and radiological indications. The effectiveness of the procedure was determined by statistical analysis of numerical scores for pain, mobility and drug consumption before and after treatment. No major complications and only three minor complications occurred. Clinically relevant improved mobility and reduction of pain and analgesics were observed, with overall significant results (p<0.0001) in all patients at 24 h after PVP and in 83 available patients at 6 months. A total of five asymptomatic refractures of cemented vertebrae and 14 new symptomatic vertebral fractures at different levels were observed between 1 and 10 months after the procedure. PVP is a safe, rapid, effective and costeffective therapy for VCFs, requiring only brief hospital admission and with long-lasting clinical results, when performed under good-quality radiological guidance, when correct indications are respected and when it is associated with rehabilitation therapy in the follow-up. It is a valid alternative to conservative therapy, which is burdened by high healthcare costs and often requires long-term immobilisation of frail and elderly patients at risk of clinical complications.

  16. Feasible modifications for the low-level waste treatment plant at Oak Ridge National Laboratory

    Energy Technology Data Exchange (ETDEWEB)

    Chilton, J.M.

    1984-06-01

    Aqueous, low-level, radioactive wastes at Oak Ridge National Laboratory (ORNL) contain small amounts of /sup 60/Co, /sup 90/Sr, /sup 137/Cs, and trace amounts of other radionuclides. These wastes are processed by passage through beds of a strong-acid cation exchange resin, and the treated water is then discharged to the environment. Studies show that pretreatment of the waste with a weak-acid cation exchange resin would result in a significant decrease in regeneration reagents and a saving of manpower. This can be accomplished in the present plant by piping changes on the existing columns. The effluent from the cation treatment process contains all of the radionuclides that are present in anionic form. Routinely, this consists only of approximately one-half of the /sup 60/Co. Under certain conditions, other anions (such as /sup 131/I) could be present. Studies show that these can be removed by use of an anion exchange resin bed at the end of the process. This would require the construction of an additional column, if the head-end treatment described above is also installed. 2 references, 2 figures, 2 tables.

    Cluster-level dynamic treatment regimens can be used to guide sequential treatment decision-making at the cluster level in order to improve outcomes at the individual or patient-level. In a cluster-level dynamic treatment regimen, the treatment is potentially adapted and re-adapted over time based on changes in the cluster that could be impacted by prior intervention, including aggregate measures of the individuals or patients that compose it. Cluster-randomized sequential multiple assignment randomized trials can be used to answer multiple open questions preventing scientists from developing high-quality cluster-level dynamic treatment regimens. In a cluster-randomized sequential multiple assignment randomized trial, sequential randomizations occur at the cluster level and outcomes are observed at the individual level. This manuscript makes two contributions to the design and analysis of cluster-randomized sequential multiple assignment randomized trials. First, a weighted least squares regression approach is proposed for comparing the mean of a patient-level outcome between the cluster-level dynamic treatment regimens embedded in a sequential multiple assignment randomized trial. The regression approach facilitates the use of baseline covariates which is often critical in the analysis of cluster-level trials. Second, sample size calculators are derived for two common cluster-randomized sequential multiple assignment randomized trial designs for use when the primary aim is a between-dynamic treatment regimen comparison of the mean of a continuous patient-level outcome. The methods are motivated by the Adaptive Implementation of Effective Programs Trial which is, to our knowledge, the first-ever cluster-randomized sequential multiple assignment randomized trial in psychiatry.

    Iron, copper, and zinc are key micronutrients that play an important role in the immune response to Mycobacterium tuberculosis. The present study aimed to evaluate the association between serum levels of those micronutrients, inflammatory markers, and the smear and culture conversion of M. tuberculosis during 60 days of tuberculosis treatment. Seventy-five male patients with pulmonary tuberculosis (mean age, 40.0 ± 10.7 years) were evaluated at baseline and again at 30 and 60 days of tuberculosis treatment. Serum levels of iron, copper, zinc, albumin, globulin, C-reactive protein, and hemoglobin, and smear and cultures for M. tuberculosis in sputum samples were analyzed. Compared to healthy subjects, at baseline, patients with PTB had lower serum iron levels, higher copper levels and copper/zinc ratio, and similar zinc levels. During the tuberculosis treatment, no significant changes in the serum levels of iron, zinc, and copper/zinc were observed. Lower serum copper levels were associated with bacteriological conversion in tuberculosis treatment (tuberculosis-negative) at 30 days but not at 60 days (tuberculosis-positive). C-reactive protein levels and the C-reactive protein/albumin ratio were lower in tuberculosis-negative patients than in tuberculosis-positive patients at 30 and 60 days after treatment. Albumin and hemoglobin levels and the albumin/globulin ratio in patients with pulmonary tuberculosis increased during the study period, regardless of the bacteriological results. High serum globulin levels did not change among pulmonary tuberculosis patients during the study. Serum copper levels and the C-reactive protein/albumin ratio may be important parameters to evaluate the persistence of non-conversion after 60 days of tuberculosis treatment, and they may serve as predictors for relapse after successful treatment.

    A 41-year-old female patient complaining of fatigue, headache, mild confusion, and rush on her lower extremities was admitted to our emergency department. Laboratory tests revealed that he had anemia, thrombocytopenia, and increased levels of indirect bilirubin and lactic dehydrogenase (LDH) in blood tests. Direct and indirect Coombs tests were negative, and fragmented erythrocytes were observed in peripheral blood smears. The patient was diagnosed with thrombotic thrombocytopenic purpura (TTP). The best supportive care was provided. Therapeutic plasma exchange (TPE) and 1 mg/kg methylprednisolone treatments were administered. On the 10th day of treatment, LDH level and fragmented red blood cells in peripheral blood smear were decreased, but his direct and indirect bilirubin levels increased despite the fact that he was treated with 1 mg/kg methylprednisolone and TPE. The patient had severe ADAMTS-13 deficiency. After discontinued steroids treatment, his bilirubin level normalized within 4 days. On the 4th day after bilirubin level normalized, vincristine treatment was administered. TPE was also continued. There was no consensus about the optimal schedule for discontinuing plasmapheresis therapy, and also we observed total bilirubin level improvement with discontinued corticosteroid treatment. In this case, corticosteroid treatment was linked with the increase of total bilirubin level in severe ADAMTS-13-deficient TTP patient.

    Several lines of evidence show that the immune system is implicated in the pathophysiology of major depressive disorder (MDD) and that treatment with antidepressants affects cytokine and C-reactive protein (CRP) levels. Few studies have investigated immune markers during non-pharmacological treatment. In this follow-up study, we investigated whether CRP and elevated plasma cytokine levels observed before treatment of an acute episode of MDD are normalized during non-pharmacological treatment. We obtained clinical assessments and blood for CRP and cytokine analysis from 50 unmedicated MDD patients, and cytokine levels from healthy controls. The patients received 'therapy as usual' for 12 weeks, and the assessments were then repeated. Of the 43 completers, 29 patients did not receive medication. In the patients receiving treatment without antidepressants, the depressive symptoms and the plasma levels of eight cytokines (interleukin (IL)-1Ra, IL-5,-6,-8,-10, G-CSF, IFN-γ, and TNF-α) were significantly reduced (P = 0.002-0.048). The cytokine levels were no longer different from the controls. The plasma CRP level did not change. Cytokine plasma levels normalized during recovery from an acute depressive episode in MDD without antidepressant treatment. These findings may have implications for the understanding of the role of the immune system in depression and recovery from depression. © 2016 John Wiley & Sons A/S.

    The aim of the study was to investigate the significance of the level of serum 25-hydroxyvitamin D3 [25-(OH)D3] and interleukin (IL)-6 in serum prior to and after immunoglobulin treatment in children suffering from Kawasaki disease in order to provide a reference for the successful treatment of Kawasaki disease in children. From February, 2013 to February, 2015, 45 patients with Kawasaki disease were enrolled in the observation group. The normal control group comprised 43 healthy volunteers and the feverish control group 46 patients with respiratory infection and fever. Venous blood was collected from each case before and after immunoglobulin treatment and the level of 25-(OH)D3 and IL-6 in the serum were measured using fluorescent quantitative PCR, enzyme-linked immunosorbent assay and western blotting. Before treatment, the level of 25-(OH)D3 in the feverish control group was significantly lower than that of the normal control group, while the level of 25-(OH)D3 in the observation group was significantly higher than that of the normal control group. The level of 25-(OH)D3 in the feverish control group was lower than the IL-6 level in the normal children, but the difference was not statistically significant (P>0.05). The level 25-(OH)D3 in the observation group was significantly higher than the IL-6 level in the normal control group. The serum content of 25-(OH)D3 was significantly higher after the treatment compared to before treatment levels and after treatment IL-6 level was only slightly lower. It was observed that the 25-(OH)D3 level in the observation group was significantly increased after immunoglobulin treatment and this was positively correlated with the effects of the treatment. The IL-6 level had no significant changes after treatment and had little correlation with the treatment effect. The results suggested that 25-(OH)D3 may be involved in the occurrence of Kawasaki disease in children and in the aggravation of the disease to some extent.

    Full Text Available years, but recently there have been reports of prophylaxis failure under natural conditions. In this study, use of the drug for prophylactic purpose against trypanosomosis in small ruminants was investigated. Forty-two sheep and 44 goats were divided into four treatment groups. Groups 1 and 2 were treated with isometamidium chloride (Samorin(R, Rhone Merieux, Lyon, France at 3-month intervals while groups 3 and 4 were used as controls. All the animals were exposed to natural tsetse challenge and monitored for serum isometamidium levels and anti-trypanosome antibodies. Seven days after drug administration, isometamidium levels were significantly higher in goats 13.7 + 0.07 ng/mℓ than in sheep 6.2 + 0.06 ng/mℓ. However, the elimination half-life in the sheep was 14.2 + 0.92 days and was significantly higher (P > 0.05 than that of the goats 12 + 0.5 days. This study established that isometamidium metabolism differs between sheep and goats and this difference may have important implications in high tsetse challenge areas.

    Full Text Available Abstract Background Adherence to antipsychotics for schizophrenia is associated with favorable clinical outcomes. This study compared annual mental-health service utilization by recent medication adherence levels for patients treated for schizophrenia, and assessed whether adherence levels change from pre- to post-psychiatric hospitalization. Methods We analyzed data from a large prospective, non-interventional study of patients treated for schizophrenia in the United States, conducted between 7/1997 and 9/2003. Detailed mental-health resource utilization was systematically abstracted from medical records and augmented with patients' self report. Medication possession ratio (MPR with any antipsychotic in the 6 months prior to enrollment was used to categorize patients as: adherent (MPR ≥ 80%, N = 1758, partially adherent (MPR ≥ 60% Results Adherent patients had a lower rate of psychiatric hospitalization compared with partially adherent and non-adherent patients (p Conclusion Adherence is associated with lower utilization of acute care services and greater engagement in outpatient mental-health treatment. Adherence is a potentially dynamic phenomenon, which may improve, at least temporarily, following patients' psychiatric hospitalizations.

    Poultry feed is a potential vector for pathogens. Heat processing and organic acid treatments may decontaminate feed and can affect bird performance as well as feed digestibility. The present study was performed to investigate the effect of different thermal treatments including pelleting (P), long-term conditioning at 85°C for 3 min (L), or expanding at 110°C (E110) and 130°C for 3 to 5 s (E130) without or with 0.75 and 1.5% organic acid supplementation (63.75% formic acid, 25.00% propionic acid, and 11.25% water) on performance, nutrient digestibility, and organ weights of broilers. In total, 960 one-day-old broiler chicks were randomly assigned to 8 replicates using a 3 × 4 factorial arrangement. Performance variables were determined, and the relative organ weights and ileal and total amino acid (AA) digestibilities were measured at d 35. The organic acid inclusion linearly improved feed efficiency in the first week (P ≤ 0.05). The acid inclusion levels and thermal treatments had no significant effect on the performance variables at later intervals of the growing period of the birds. The L group showed the lowest ileal AA and CP digestibility. The inclusion of organic acids had a quadratic effect on total and ileal digestibility of isoleucine (P ≤ 0.05), whereas it had no significant effect on the ileal digestibility of other AA and nutrients. The relative weights of the jejunum and small intestine were significantly higher in the E130 group compared with P and L (P ≤ 0.05). In conclusion, our study demonstrated that long-term heat conditioning can decrease ileal nutrient digestibility, whereas pelleting and expansion, independently of organic acid addition, seemed to have no negative impact on broiler performance and nutrient digestibilities. Moreover, adding a blend of organic acids to broiler diets had neither positive nor negative effects on nutrient digestibility and final broiler performance. This indicates the feasibility of short-term thermal

    Full Text Available Ribavirin blood levels vary considerably between patients with standard weight-based dosing. Their impact on sustained virological response (SVR with pegylated interferon and ribavirin is controversial, but has mostly been studied before the IL28b gene polymorphism as a possible confounder was discovered.The impact of serum ribavirin trough levels at week 4, at the end of treatment and of mean levels across the entire antiviral treatment with pegylated interferon and ribavirin on relapse, SVR rates and anemia was retrospectively studied by univariate and multivariable logistic regression analyses in 214 patients with HCV genotype 1-4 infection, including 88 patients with available IL28b genotyping.Mean ribavirin levels varied between 0.68-5.65 mg/l and significantly differed between patients with or without SVR. By multivariable regression including age, sex, HCV viral load, HCV genotype, liver fibrosis stage, prior treatments, immunosuppression and IL28b genotype, ribavirin levels consistently displayed significant influence on SVR and relapse without indication for a specific importance of higher concentrations early or late in the treatment course. Although hemoglobin decline was on average more pronounced in patients with higher ribavirin levels, hemoglobin remained relatively stable in a significant proportion of these, indicating that ribavirin levels alone are insufficient to predict anemia.While data are scarce to draw conclusions applicable for modern DAA therapies, these results support ribavirin treatment based on serum levels instead of purely weight-based dosing in combination with pegylated interferon.

    Full Text Available OBJECTIVE: The primary objective of our study was to investigate effects of antiproteinuric treatment on lipid levels of patients with idiopathic focal segmental glomerulosclerosis (FSGS or membranous glomerulonephritis (MGN.MATERIAL and METHODS: The clinical and laboratory data of the patients were recorded at three-month intervals during 18 months of follow-up. Patients with non-nephrotic proteinuria without hypoalbuminemia received conservative treatment while those with more severe disease received steroid therapy as well. Lipid parameters in the two groups and the factors effective on these parameters were investigated.RESULTS: Sixty eight patients (36 with FSGS, 32 with MG were included. The mean age of the patients and the follow-up period were 39.6±16.6 years and 16.4±8.9months, respectively. 36 (53% patients received steroid therapy. The percentage of patients taking antilipemic treatment was statistically significantly higher in the group taking steroid therapy. LDL cholesterol levels were higher at the beginning in patients taking steroid therapy but the difference disappeared after the ninth month. Total and LDL cholesterol levels showed a negative correlation with albumin levels and a positive correlation with proteinuria level.CONCLUSION: Treatment of hyperlipidemia in nephrotic syndrome should be directed towards increasing serum albumin levels, and therefore treatment of the glomerular disease. Antilipidemic therapies should be considered in patients who do not respond to other antiproteinuric treatment.

    Background C-reactive protein is an inflammatory biomarker and its level increases in the serum of psoriatic patients. Its level is also associated with Psoriasis Area and Severity Index score. Objective The aim of this study was to assess the decrement of serum C-reactive protein level with narrow-band ultraviolet B (NB-UVB) therapy. Methods C-reactive protein serum levels in psoriasis patients were measured before and after treatment with NB-UVB and the data were analyzed in relation to the Psoriasis Area and Severity Index score improvement. Results Baseline C-reactive protein levels among psoriatic patients were higher than normal. These levels decreased significantly after treatment (P<0.001). At the beginning of the study, patients with higher levels of C-reactive protein also had more extensive and severe skin involvement. The highest decrease in C-reactive protein was observed in patients who responded better to the treatment and achieved a higher Psoriasis Area and Severity Index 75%. There was an association between baseline Psoriasis Area and Severity Index scores and C-reactive protein levels. Conclusion Patients with moderate to severe plaque-type psoriasis had active systemic inflammation, which was demonstrated by increased levels of C-reactive protein. Furthermore, skin disease severity was correlated with C-reactive protein levels. Phototherapy healed the psoriatic skin lesions and reduced inflammation, while decreasing C-reactive protein levels.

    Full Text Available Adherence to pharmacological treatment for hypertension is considered a key factor in guaranteeing successful therapy outcomes. Knowledge of the disease, its complications, as well as the need for changes in lifestyle, call for patient motivation and continuous interactive education. The evidence regarding the beneficial effects of changes in life style by hypertensive individuals in reducing the complications of the disease, as well as in its prevention are indisputable. However, the challenges posed by patient adherence to treatment prescribed by doctors remain. The aim of this study was to assess blood pressure levels together with degree of adherence to pharmacological treatment with Enalapril Maleate by means of the Morisky-Green Test, in hypertensive patients who were users of a School Pharmacy. Of the 102 patients interviewed, 65.7% had controlled blood pressure, but only 36.3% indicated total compliance with the pharmacological treatment. The Morisky-Green test proved ineffective in associating controlled blood pressure levels and positive attitudes toward taking antihypertensive medicines.A adesão ao tratamento farmacológico da hipertensão arterial sistêmica é considerada uma das etapas essenciais para a garantia do seu sucesso. Para tanto, o conhecimento da doença, suas complicações e necessidade de mudanças em relação ao estilo de vida, requer do paciente, além da motivação, a educação contínua e de modo compartilhado. A evidência quanto aos efeitos benéficos da mudança do estilo de vida pelo portador de hipertensão na redução das complicações desta doença, bem como em sua prevenção, já não são mais questionados, porém o desafio continua residindo na adesão do indivíduo ao padrão de tratamento prescrito pelo médico. Este estudo teve como objetivo avaliar os níveis de pressão arterial, assim como o nível de adesão ao tratamento farmacológico com maleato de enalapril de pacientes portadores de

    Randomised controlled trials report group-level treatment effects. However, an individual patient confronting a treatment decision needs to know whether that person's expected treatment benefit will exceed the expected treatment harm. We describe a flexible model for individualising a treatment decision. It individualises group-level results from randomised trials using clinical prediction guides. We constructed models that estimate the size of individualised absolute risk reduction (ARR) for the target outcome that is required to offset individualised absolute risk increase (ARI) for the treatment harm. Inputs to the model include estimates for the individualised predicted absolute treatment benefit and harm, and the relative value assigned by the patient to harm/benefit. A decision rule recommends treatment when the predicted benefit exceeds the predicted harm, value-adjusted. We also derived expressions for the maximum treatment harm, or the maximum relative value for harm/benefit, above which treatment would not be recommended. For the simpler model, including one kind of benefit and one kind of harm, the individualised ARR required to justify treatment was expressed as required ARRtarget(i)=ARIharm(i) × RVharm/target(i). A complex model was also developed, applicable to treatments causing multiple kinds of benefits and/or harms. We demonstrated the applicability of the models to treatments tested in superiority trials (either placebo or active control, either fixed harm or variable harm) and non-inferiority trials. Individualised treatment recommendations can be derived using a model that applies clinical prediction guides to the results of randomised trials in order to identify which individual patients are likely to derive a clinically important benefit from the treatment. The resulting individualised prediction-based recommendations require validation by comparison with strategies of treat all or treat none.

    Full Text Available Poplar has emerged as a model plant for understanding molecular mechanisms of tree growth, development and response to environment. Long-term application of different forms of nitrogen (such as NO3--N and NH4+-N may cause morphological changes of poplar roots; however, the molecular level changes are still not well known. In this study, we analyzed the expression profiling of poplar roots treated by three forms of nitrogen: S1 (NH4+, S2 (NH4NO3 and S3 (NO3- by using RNA-SEQ technique. We found 463 genes significantly differentially expressed in roots by different N treatments, of which a total of 116 genes were found to differentially express between S1 and S2, 173 genes between S2 and S3, and 327 genes between S1 and S3. A cluster analysis shows significant difference in many transcription factor families and functional genes family under different N forms. Through an analysis of Mapman metabolic pathway, we found that the significantly differentially expressed genes are associated with fermentation, glycolysis and tricarboxylic acid cycle (TCA, secondary metabolism, hormone metabolism, and transport processing. Interestingly, we did not find significantly differentially expressed genes in N metabolism pathway, mitochondrial electron transport / ATP synthesis and mineral nutrition. We also found abundant candidate genes (20 transcription factors and 30 functional genes regulating morphology changes of poplar roots under the three N forms. The results obtained are beneficial to a better understanding of the potential molecular and cellular mechanisms regulating root morphology changes under different N treatments.

    From 1993 to 1996, the Department of Energy, Environmental Management, Office of Science and Technology (OST), has sponsored a series of systems analyses to guide its future research and development (R&D) programs for the treatment of mixed low-level waste (MLLW) stored in the DOE complex. The two original studies were of 20 mature and innovative thermal systems. As a result of a technical review of these thermal system studies, a similar study of five innovative nonthermal systems was conducted in which unit operations are limited to temperatures less than 350{degrees}C to minimize volatilization of heavy metals and radionuclides, and de novo production of dioxins and furans in the offgas. Public involvement in the INTS study was established through a working group of 20 tribal and stakeholder representatives to provide input to the INTS studies and identify principles against which the systems should be designed and evaluated. Pre-conceptual designs were developed for all systems to treat the same waste input (2927 lbs/hr) in a single centralized facility operating 4032 hours per year for 20 years. This inventory consisted of a wide range of combustible and non-combustible materials such as paper, plastics, metals, concrete, soils, sludges, liquids, etc., contaminated with trace quantities of radioactive materials and RCRA regulated wastes. From this inventory, an average waste profile was developed for simulated treatment using ASPEN PLUS{copyright} for mass balance calculations. Seven representative thermal systems were selected for comparison with the five nonthermal systems. This report presents the comparisons against the TSWG principles, of total life cycle cost (TLCC), and of other system performance indicators such as energy requirements, reagent requirements, land use, final waste volume, aqueous and gaseous effluents, etc.

    We attempted to investigate whether dehydroepiandrosterone sulfate (DHEA-S) levels are associated with remission of major depressive disorder by assessing scores on the 17-Item Structured Interview Guide for the Hamilton Depression before and after antidepressant treatment. Plasma DHEA-S levels in 24 patients diagnosed with major depressive disorder on the basis of Diagnostic and Statistical Manual of Mental Disorders, fourth edition (text revision) before and after antidepressant treatment, and 24 healthy, gender-matched, and age-matched controls were measured using a radioimmunoassay kit. Plasma DHEA-S levels in patients were significantly higher than those in healthy controls. In patients who achieved remission after antidepressant treatment, plasma DHEA-S levels significantly declined compared with the levels before treatment. A significant correlation was observed between changes in DHEA-S levels and Absence of Depressive and Anxious Mood scores, which are calculated from the 2-Item Structured Interview Guide for the Hamilton Depression rating as follows: severity of depressive mood and anxiety in patients before and after antidepressant treatment. These findings suggest that plasma DHEA-S levels can be used as a putative indicator of the state of remission in patients with major depressive disorder. Copyright © 2014 John Wiley & Sons, Ltd.

    Today there exist many almost overfilled storage tanks with liquid radioactive waste in the Russian Federation. This waste was generated over several years by the civil and military utilization of nuclear power. The current waste treatment capacity is either not available or inadequate. Following the London Convention, dumping of the waste in the Arctic seas is no longer an alternative. Waste is being generated from today's operations, and large volumes are expected to be generated from the dismantling of decommissioned nuclear submarines. The US and Norway have an ongoing co-operation project with the Russian Federation to upgrade and expand the capacity of a treatment facility for low level liquid waste at the RTP Atomflot site in Murmansk. The capacity will be increased from 1,200 m{sup 3}/year to 5,000 m{sup 3} /year. The facility will also be able to treat high saline waste. The construction phase will be completed the first half of 1998. This will be followed by a start-up and a one year post-construction phase, with US and Norwegian involvement for the entire project. The new facility will consist of 9 units containing various electrochemical, filtration, and sorbent-based treatment systems. The units will be housed in two existing buildings, and must meet more stringent radiation protection requirements that were not enacted when the facility was originally designed. The US and Norwegian technical teams have evaluated the Russian design and associated documentation. The Russian partners send monthly progress reports to US and Norway. Not only technical issues must be overcome but also cultural differences resulting from different methods of management techniques. Six to eight hour time differentials between the partners make real time decisions difficult and relying on electronic age tools becomes extremely important. Language difficulties is another challenge that must be solved. Finding a common vocabulary, and working through interpreters make the

    The overall task of this program was to provide an assessment of currently available technology for treating commercial low-level radioactive waste (LLRW), to initiate development of a methodology for choosing one technology for a given application, and to identify research needed to improve current treatment techniques and decision methodology. The resulting report is issued in four volumes. Volume 2 discusses the definition, forms, and sources of LLRW; regulatory constraints affecting treatment, storage, transportation, and disposal; current technologies used for treatment, packaging, storage, transportation, and disposal; and the development of a matrix relating treatment technology to the LLRW stream as an aid for choosing methods for treating the waste. Detailed discussions are presented for most LLRW treatment methods, such as aqueous processes (e.g., filtration, ion exchange); dewatering (e.g., evaporation, centrifugation); sorting/segregation; mechanical treatment (e.g., shredding, baling, compaction); thermal processes (e.g., incineration, vitrification); solidification (e.g., cement, asphalt); and biological treatment.

    The long-term clinical impact of low-level viremia (LLV; <2,000 IU/mL) is not well understood. As a result, it is unclear whether the development of LLV during entecavir monotherapy requires a change in therapy. A retrospective cohort of 875 treatment-naive chronic hepatitis B virus (HBV) monoinfected patients (mean age 47.7 years, male = 564 [65.5%], cirrhosis = 443 [50.6%]) who received entecavir monotherapy were analyzed for the development of hepatocellular carcinoma (HCC). The HCC risk was compared between patients who maintained virological response (MVR), defined by persistently undetectable HBV DNA (<12 IU/mL), and patients who experienced LLV, defined by either persistent or intermittent episodes of <2,000 IU/mL detectable HBV DNA. During a median 4.5 years of follow-up (range 1.0-8.7 years), HCC was diagnosed in 85 patients (9.7%). HCC developed more frequently in patients who experienced LLV than MVR (14.3% versus 7.5% at 5 years, P = 0.015). The hazard ratio comparing those with LLV to MVR was 1.98 (95% confidence interval = 1.28-3.06, P = 0.002, adjusted for age, sex, hepatitis B e antigen, baseline HBV DNA levels, and cirrhosis). Among patients with cirrhosis, those with LLV exhibited a significantly higher HCC risk than those with MVR (HCC incidence rate at 5 years 23.4% versus 10.3%, adjusted hazard ratio = 2.20, 95% confidence interval 1.34-3.60; P = 0.002). However, for patients without cirrhosis, there was no significant difference in the HCC risk between LLV and MVR. LLV observed during entecavir monotherapy was associated with a higher risk of HCC, especially for those with cirrhosis, indicating that LLV during potent antiviral therapy is consequential.

    Clinical stage 1 (CS1) testicular seminoma involves an almost 100 % disease-specific survival in controlled clinical trials. We aimed to find out whether these results can be matched in patients managed on the routine care level. In total, 725 patients with seminoma CS1 were prospectively enrolled from 130 institutions. Adjuvant management as decided by local physicians involved surveillance (n = 256), radiotherapy (41), 1× Carboplatin (362), and 2× Carboplatin (66). We registered type of management, age, duration of follow-up (F/U), relapse, rete testis invasion (RTI), and tumor size. Actuarial relapse-free survival curves were calculated for treatment modalities and stratified for tumor sizes and RTI. A Cox regression model was calculated to explore for factors influencing relapses. Disease-specific survival was 100 %. Crude relapse rates were 8.2, 2.4, 5.0, and 1.5 % for surveillance, radiotherapy, 1× Carboplatin, and 2× Carboplatin after a median F/U of 30 months. RTI and tumor size were not associated with progression in surveillance patients. One course Carboplatin caused relapses in 6.8 % in tumor sizes >4 cm and 9.3 % (actuarial 13 %) in sizes >5 cm. The Cox model revealed the association of tumor size with recurrence in the entire seminoma population (Hazard ratio 1.17; 95 % confidence intervals 1.03-1.33). The overall outcome of CS1 seminoma managed on the routine care level mirrors that of controlled trials. Unexpectedly, the risk factors in surveillance patients were not confirmed, but tumor size proved to be a risk indicator in the entire group of seminoma. Importantly, one course Carboplatin involved low efficacy to control the disease in large tumors.

    Objective The aim of this retrospective longitudinal naturalistic study was to evaluate the effects of maintenance lithium treatment on parathyroid hormone (PTH) and calcium levels. Methods A retrospective longitudinal naturalistic study design was used. Data were collected from the database of a tertiary psychiatric center covering the years 2010–2014. Included were bipolar patients who had never been exposed to lithium and had lithium started, and who had PTH, and total and ionized calcium levels available before and during lithium treatment. Paired t-tests were used to analyze changes in PTH and calcium levels. Linear regressions were performed, with mean lithium level and duration of lithium exposure as independent variables and change in PTH levels as dependent variable. Results A total 31 patients were included. The mean duration of lithium treatment was 18.6±11.4 months. PTH levels significantly increased during lithium treatment (+13.55±14.20 pg/mL); the rate of hyperparathyroidism was 12.9%. Neither total nor ionized calcium increased from baseline to follow-up; none of our patients developed hypercalcemia. Linear regressions analyses did not show an effect of duration of lithium exposure or mean lithium level on PTH levels. Conclusion Lithium-associated stimulation of parathyroid function is more common than assumed to date. Among parameters to be evaluated prior to lithium implementation, calcium and PTH should be added. PMID:26229473

    To evaluate the efficacy of cyanocobalamin treatment in patients having recurrent aphthous ulcers (RAUs) with normal or decreased serum vitamin B12 (cobalamin) levels. Seventy-two patients with RAU were included in the study. In addition to serum cobalamin levels, hemanitic and biochemistrical parameters were measured. Patients with serum cobalamin levels or = 140 pg/mL were defined as the cobalamin normal group (CNG). The degree of aphthous ulcer healing was determined according to serum cobalamin levels at the first and sixth month after cyanocobalamin treatment protocol. Of the 72 participants, 37 were in the CDG whereas 35 were considered to have normal cobalamin levels. In the first admission the cobalamin levels were 215.8 +/- 116.90 pg/mL in CNG and 107.43 +/- 29.35 pg/mL in the CDG. The frequency of aphthous ulcers was defined numerically according to monthly occurrence of the lesions. The mean aphthous ulcer frequency in CNG group was 1.9 +/- 0.7, whereas it was 2.4 +/- 0.9 in the CDG. A significant increase in cobalamin levels was observed after cyanocobalamin treatment in both groups. A significant decrease in aphthous ulcer frequency was also concurrently observed. 96% of the patients showed good response to replacement treatment, 4% of the study population did not respond to the treatment. Cyanocobalamin treatment maybe beneficial for patients with RAU even when serum cobalamin levels are normal. We suggest that higher serum cobalamin levels should be attained in patients with RAU for mucosal protection.

The major survival factor for B cells, BAFF has been shown to play a role in several autoimmune conditions. Elevated BAFF levels have been reported in MS animal model and during MS relapse in patients. Moreover, disease-modifying treatments (DMT reportedly influence blood BAFF levels in MS patients, but the significance of these changes remains unclear. The present study addresses how blood BAFF levels are associated with the clinical course of relapsing-remitting MS and the effectiveness of DMT and short-term steroid treatment. During a prospective longitudinal follow-up of 2.3 years, BAFF was measured in the blood of 170 MS patients in the stable phase and within 186 relapses. BAFF levels were significantly higher in MS patients compared to healthy controls. However, stable MS patients without relapses exhibited significantly higher BAFF levels than relapsing patients. Treatment with interferon-β and immunosuppressants raised BAFF blood levels. Interestingly, a similar effect was not seen in patients treated with glatiramer acetate. Short-term treatment with high doses of intravenous methylprednisolone did not significantly alter plasma BAFF levels in 65% of relapsing-remitting MS patients. BAFF were correlated weakly but significantly with monocyte and basophil counts, but not with other blood cell types (neutrophils, lymphocytes, or eosinophils or inflammatory biomarkers. To our knowledge, this is the first report demonstrating that higher blood BAFF levels may reflect a more stable and effective MS treatment outcome. These results challenge hypotheses suggesting that elevated blood BAFF levels are associated with more severe disease presentation and could explain the recent failure of pharmaceutical

    Diagnosis-related groups (DRGs) are widely used in Europe. They allow performing comparisons in hospitals and incurrent hospital payment systems, defining the payment categories. We undertook this study to classify children who underwent appendectomy according to DRGs. Cross-sectional study. Comorbidities, length of hospitalization, histopathologic classification, and DRG classifications were analyzed. We included 313 patients, 62% males, with an average age of 8 ± 3 years; 91% were referred by another hospital and 67% were treated at night. Average length of hospitalization was 4 ± 3 days. There were comorbidities in 8% and surgical complications in 11%. According to histopathology, appendicitis was edematous (11%), suppurative (36%), gangrenous (22%), perforated (29%), and abscessed (2%). At discharge, 97% of the patients were healthy. Total cost for DRG 343 was $10,470,173.00 (Mexican pesos), DRG 342 was $1,227,592.00 and DRG 340 was $511,521.00. The global amount was $12,209,286.00 (Mexican pesos). The unitary cost for treatment of appendectomy for DRG 343 was $37,935.00, for DRG 342 was $49,103.00 and for DRG 340 was $42,626.00 (Mexican pesos). Because 88% of the cases of appendicitis were uncomplicated, this amount of money could be spent to treat these patients in a second-level hospital, using reimbursement 343 without generating additional expenses.

    Bronchial asthma is a common disease in both the pediatric and adult populations, characterized by wide variations over short periods of time in resistance to airflow in intrapulmonary airways. A primary goal in the use of low- level laser therapy (LLLT) was the safe, effective and rapid palliation of symptoms owing to tracheal or bronchial obstruction. We have investigated the effects of LLLT comparatively with other modality trials in children's asthma. In the study were included 98 patients aged 10-18 years diagnosed with moderate or severe asthma, in attack- free period. The patients were divided into 3 groups. Group 1 received only laser therapy using extra meridian acupuncture points and scanning technique. Group 2 was treated only with inhaled Serevent 2 X 25 micrometers , two times daily, 3 months. Group 3 was tread with Theophylline retard in dosage of 15-mg/kg/12 h, 3 months. At the end of treatment we remarked a noticeable improvement of the clinical, functional and immunological characteristics at 83 percent of patients in group 1, comparatively with only 70 percent (group 2) and 53 percent (group 3). The LLLT had a very good action on bronchial patency , displayed an immunocorrecting action and is recommended in attack-free periods at children.

    Full Text Available OBJECTIVE: To investigate whether changes in the plasma level of soluble urokinase plasminogen activator receptor (suPAR can be used to monitor tuberculosis (TB treatment efficacy. DESIGN: This prospective cohort study included 278 patients diagnosed with active pulmonary TB and followed throughout the 8-month treatment period. RESULTS: Mortality during treatment was higher in the highest inclusion quartile of suPAR (23% compared to the lowest three quartiles (7%, the risk ratio being 3.1 (95% CI 1.65-6.07. No association between early smear conversion and subsequent mortality or inclusion suPAR was observed. After 1 and 2 months of treatment, an increase in suPAR compared to at diagnosis was associated with a Mortality Rate Ratio (MRR of 4.5 (95%CI: 1.45-14.1 and 2.1 (95%CI 0.62-6.82, respectively, for the remaining treatment period. CONCLUSIONS: The present study confirmed that elevated suPAR level at time of initiation of TB treatment is associated with increased risk of mortality. Furthermore, increased suPAR levels after one month of treatment was associated with increased risk of mortality during the remaining 7-month treatment period.

    Since intensive efforts ofprophylaxis including fluoridisation, better oral hygiene, eating ofless sugar containing foods, reduced the risk ofcaries and the problems ofcaries lesions significantly. But, especially beginning at the age of3O years more than 80 % ofthe population in almost every nation shows signs of periodontal defects. This you can call an epidemic disease. Because people get older and expect a lot concerning their outlook, their esthetic, their phonetic, they have great expectations towards their natural dentition and keep their own teeth. This is a great challenge to periodontal prophylaxis and periodontal therapy. According to the progress ofthe disease different therapies are indicated. Starting with oral hygiene instructions to establish better oral hygiene with all the modem technologies ofmicrobiological investigations, pharmaceutical therapy, physiotherapy, low level laser treatment, periodontal-surgery, like curettage, deepscaling and rootplaning but also more sophisticated teatmentplans with gingivoplasty, gingivectomy, flap-procedures and mucogingival surgeiy including bone fillings, regenerativ technics the whole spectrum oftreatment options has widely expanded during the last years.

    This report summarizes the formulation of surrogate waste packages, representing the major bulk constituent compositions for 12 waste stream classifications selected by the US DOE Mixed Waste Treatment Program. These waste groupings include: neutral aqueous wastes; aqueous halogenated organic liquids; ash; high organic content sludges; adsorbed aqueous and organic liquids; cement sludges, ashes, and solids; chloride; sulfate, and nitrate salts; organic matrix solids; heterogeneous debris; bulk combustibles; lab packs; and lead shapes. Insofar as possible, formulation of surrogate waste packages are referenced to authentic wastes in inventory within the DOE; however, the surrogate waste packages are intended to represent generic treatability group compositions. The intent is to specify a nonradiological synthetic mixture, with a minimal number of readily available components, that can be used to represent the significant challenges anticipated for treatment of the specified waste class. Performance testing and evaluation with use of a consistent series of surrogate wastes will provide a means for the initial assessment (and intercomparability) of candidate treatment technology applicability and performance. Originally the surrogate wastes were intended for use with emerging thermal treatment systems, but use may be extended to select nonthermal systems as well.

    Vaginal promestriene was tested in gynecological cancer patients who suffered from severe vaginal dryness and dyspareunia. This form of estrogen has a low level of vaginal absorption and proved to be effective for vaginal atrophy. 17 patients were treated with a 10mg soft vaginal suppository daily for one month. Plasma levels of estrone sulfate (E1S), used as the marker of overall estrogenicity, were measured by liquid chromatography in combination with mass spectrometry. Mean E1S levels changed from 533 (22-2920) to 374 (81-856) pg/ml (p=0.39). In highly symptomatic gynecological cancer patients the level of circulating estrone sulfate was not significantly affected by vaginal promestriene treatment overall, but a wide range of levels was noted pre and post treatment in individual patients.

    IL-1 generation by mononuclear phagocytes, IL-4 production by Th2 lymphocytes and IgE levels in serum were measured in eight patients with acute fasciolosis and seven patients in the chronic stage of the disease before and after triclabendazole treatment. Results were compared with those of a control group of ten individuals. The monocytes and lymphocytes from patients with acute and chronic fasciolosis produced significantly lower levels of IL-1 and IL-4 respectively, particularly in the chronic phase of the disease, as compared to the control. A significant increase in IgE level in both acute and chronic fasciolosis was observed. The level was significantly higher in acute as compared to chronic cases. After treatment with triclabendazole IL-1, IL-4 and IgE levels moved towards the control indicating obvious improvement in the immunological responses of the patients.

  10. REMARKS ON THE ACCOUNTING TREATMENT OF GOODWILL AT THE LEVEL OF BLOCKS OF TRADING COMPANIES

    Directory of Open Access Journals (Sweden)

    Violeta Isai

    2015-05-01

    Full Text Available This paper presents the accounting treatment of goodwill, namely, its recognition, assessment and accounting, as part of the patrimonial assets of an economic entity. Specific, due to its structure, to any blocks of companies, the goodwill represents the cost surplus of an active block to the market value of the net purchased assets. Why would anyone pay for a company more than its actual accounting worth? Because the extra price is usually attributed to those intangible elements that cannot be assessed separately but whose horizon of expectation is usually related to prospective economic advantages such as the clientele, the top commercial location, the employees' level of training, market shares, good relationships with the employees, the suppliers, the banks etc. Many of the Romanian economic entities were sold at a price that was inferior to their accounting value because, following their assessment, the experts were able to ascertain the following: the existence of fixed assets that needed to be scrapped; the existence of stocks that were either depreciated or difficult to sell; the existence of outstanding debts that were either uncertain of lost for good; the existence of major debts carrying interest. The effect of such assessments led to a reduced marked value of all assets and an increased market value of the debts, or in other words, the possibility of a badwill occurrence. The relationship goodwill – badwill, specific to the blocks of trading companies, represents a current challenge in the recognition and evaluation of the goodwill in compliance with the current Romanian legislation as harmonized with the international accountancy standards.

    This appendix contains the mixed and low-level waste engineering design files (EDFS) documenting each low-level and mixed waste stream investigated during preengineering studies for Mixed and Low-Level Waste Treatment Facility Project. The EDFs provide background information on mixed and low-level waste generated at the Idaho National Engineering Laboratory. They identify, characterize, and provide treatment strategies for the waste streams. Mixed waste is waste containing both radioactive and hazardous components as defined by the Atomic Energy Act and the Resource Conservation and Recovery Act, respectively. Low-level waste is waste that contains radioactivity and is not classified as high-level waste, transuranic waste, spent nuclear fuel, or 11e(2) byproduct material as defined by DOE 5820.2A. Test specimens of fissionable material irradiated for research and development only, and not for the production of power or plutonium, may be classified as low-level waste, provided the concentration of transuranic is less than 100 nCi/g. This appendix is a tool that clarifies presentation format for the EDFS. The EDFs contain waste stream characterization data and potential treatment strategies that will facilitate system tradeoff studies and conceptual design development. A total of 43 mixed waste and 55 low-level waste EDFs are provided.

    Subclinical hypothyroidism (SH) occurs when serum thyroid stimulating hormone (TSH) concentrations are raised and serum thyroid hormone concentrations are normal. The effect of SH on the proinflammatory adipose cytokine releasing visceral adipose tissue (VAT) is not clear. The aim of this study is to identify the difference between the pre and posttreatment levels of VAT, leptin, and resistin in SH patients. There were 51 SH patients and 43 age- and gender-matched healthy subjects included in the study. Thyroid functions, biochemical tests, leptin, resistin, and visceral and subcutaneous fat measurements were made. The measurements were repeated in the SH group in the third month following L-thyroxin treatment. Initially, high sensitivity C-reactive protein, carotid artery intima-media thickness (mm), leptin, and resistin levels were significantly higher in the SH group compared to the controls, while the other parameters were similar. While no correlation was observed between TSH levels and adipokines, a positive correlation was detected between waist circumference and leptin levels (r = 0.549, p adipose tissue was positively correlated to age, waist circumference, and leptin levels, but negatively correlated to free thyroxin (T4) levels (r = 0.419, p = 0.009; r = 0.794, p leptin, and resistin levels of SH patients following levothyroxine treatment. Conclusion The reduced VAT volume, leptin, and resistin levels in SH patients following treatment may support the idea that TSH affects adipose tissue functions.

    We report findings from a community-based two-city survey of homeless adults comparing the level of substance abuse treatment assigned to them using the ASAM Patient Placement Criteria with care actually received during the previous 12 months. Overall 531 adults were surveyed with 382 meeting DSM-IIIR criteria of being in need of treatment or having a demand for treatment. Of those with a treatment need, 1.5% met criteria for outpatient care, 40.3% intensive outpatient/partial hospitalization care, 29.8% medically monitored care and 28.8% managed care levels. In contrast, of those receiving treatment (50.5%, 162 persons), almost all care received by this cohort was either inpatient or residential based (83.6%). Unsheltered homeless persons and those without insurance were significantly more likely to report not receiving needed treatment. Lack of treatment availability or capacity, expense, and changing one's mind while on a wait list were the most commonly cited reasons for no treatment.

Serum levels of homocysteine, leptin, fibrinogen, CRP, total cholesterol (TC, high-density lipoprotein cholesterol (HDL-C, low-density lipoprotein cholesterol (LDL-C and ESR were measured and body mass index (BMI were calculated before and after treatment of hyperthyroidism.Results: Pretreatment t-hcy, TC, LDL-C, HDL-C levels and BMI of patients were significantly lower than those of the post-treatment (p<0.001, for each variable. However, fibrinogen and ESR decreased after the treatment (p<0.001 and p<0.05, respectively. There were no differences in leptin and CRP levels between pre- and post-treatment periods. Pre and post treatment TC and LDL-C levels were negatively correlated with free triiodothyronine (fT3 levels (r=-0.588, p<0.01; r=-0.534, p<0.01; r=-0.543, p<0.01 and r =-0.653, p<0.01, respectively. Pre-treatment HDL-C was inversely correlated with TSH (r=-0.423, p<0.05. Pre-post- treatment LDL-C was negatively correlated with free thyroxine (fT4 levels (r=-0.536, p<0.001 and r=- 0.422, p<0.05 respectively. Pre-treatment TC was inversely correlated with fT4 (r=-0.590, p<0.01.Conclusion: Hyperthyroidism is associated with high plasma fibrinogen and ESR levels. Elevated plasma fibrinogen and ESR levels may be a possible explanation for the high cardiovascular morbidity among hyperthyroidic subjects. These changes may reflect low-grade inflammation or disturbances in coagulation in hyperthyroidism.

    Asthma guidelines aim to guide health practitioners to optimise treatment for patients to minimise symptoms, improve or maintain good lung function, and prevent acute exacerbations. The principle of asthma guidelines is based on a step-up or step-down regimen of asthma medications to maximise health using minimum doses. Fractional exhaled nitric oxide (FeNO) is a marker of eosinophilic inflammation and tailoring asthma medications in accordance to airway eosinophilic levels may improve asthma outcomes such as indices of control or reduce exacerbations, or both. To evaluate the efficacy of tailoring asthma interventions based on fractional exhaled nitric oxide (FeNO), in comparison to not using FeNO, that is, management based on clinical symptoms (with or without spirometry/peak flow) or asthma guidelines (or both), for asthma-related outcomes in children. We searched the Cochrane Airways Group Specialised Register of Trials, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and reference lists of articles. The last searches were in June 2016. All randomised controlled trials (RCTs) comparing adjustment of asthma medications based on FeNO levels compared to those not using FeNO, that is, management based on clinical symptoms or asthma guidelines (or both) involving children. We reviewed results of searches against predetermined criteria for inclusion. Two review authors independently selected relevant studies, assessed trial quality and extracted data. We contacted study authors for further information with responses provided from three. The review included nine studies; these studies differed in a variety of ways including definition of asthma exacerbations, FeNO cut-off levels used (12 parts per billion (ppb) to 30 ppb), the way in which FeNO was used to adjust therapy and duration of study (6 to 12 months). Of 1426 children randomised, 1329 completed the studies. The inclusion criteria for the participants in each study varied but all

    Boiling histotripsy (BH) is a high-intensity focused ultrasound (HIFU)-based method of mechanical tissue fractionation that utilizes millisecond-long bursts of HIFU shock waves to cause boiling at the focus in milliseconds. The subsequent interaction of the incoming shocks with the vapor bubble mechanically lyses surrounding tissue and cells. The acoustic parameter space for BH has been investigated previously and an inverse dependence between the HIFU frequency and the dimensions of a BH lesion has been observed. The primary goal of the present study was to investigate in more detail the ablation rate and reliability of BH in the frequency range relevant to treatment of deep abdominal tissue targets (1-2 MHz). The second goal was to investigate the effect of focal peak pressure levels and shock amplitude on BH lesion formation, given a constant duty factor, a constant ratio of the pulse duration to the time to reach boiling and a constant number of BH pulses. A custom-built 12-element sector array HIFU transducer with F-number = 1.05 was used in all experiments. BH pulses at 5 different frequencies (1, 1.2, 1.5, 1.7 and 1.9 MHz) were delivered to optically transparent polyacrylamide gel phantoms and ex vivo bovine liver and myocardium tissue to observe cavitation and boiling bubble activity with high-speed photography and B-mode ultrasound imaging, correspondingly. In gel phantoms, a cavitation bubble cloud was shown to form prefocally and to shield the focus in all exposures at 1 and 1.2 MHz and in the highest amplitude exposures at 1.5-1.7 MHz; shielding was not observed at 1.9 MHz. In ex vivo tissue, this shielding effect was observed in 25% of exposures when peak negative in situ pressure exceeded 10.2 MPa at 1 MHz and 14.5 MPa at 1.5 MHz. When shielding occurred, the exposures resulted in mild tissue disruption in the prefocal region, but not liquefaction. The dimensions of liquefied lesions followed the inverse proportionality trend with

    Serum amino-terminal propeptide of C-type natriuretic peptide (NT-proCNP) levels have been proposed as a biomarker of linear growth in healthy children. The usefulness of NT-proCNP in patients with achondroplasia (ACH)/hypochondroplasia (HCH) remains to be elucidated. The objective was to study whether serum NT-proCNP level is a good biomarker for growth in ACH/HCH and other patients of short stature. This was a longitudinal cohort study. Sixteen children with ACH (aged 0·4-4·3 years), six children with HCH (2·7-6·3 years), 23 children with idiopathic short stature (ISS) (2·2-9·0 years), eight short children with GH deficiency (GHD) (2·9-6·8 years) and five short children born small for gestational age (SGA) (2·0-6·6 years). Patients with ACH/HCH received GH treatment for 1 year. Serum NT-proCNP levels and height were measured. NT-proCNP levels positively correlated with height velocity in these short children (P treatment (P treatment for 1 year was positively correlated with the changes in NT-proCNP levels after the initiation of GH (P treatment on growth in patients with ACH/HCH at least in the first year and height velocity in short stature patients. © 2016 John Wiley & Sons Ltd.

    Pharmaceutical wastewater treatment plants (PWWTPs) receive industrial effluents from the plant that contain extremely high levels of antibiotics and are regarded as one of the major sources of antibiotics in the environment. Two PWWTPs have been selected in Zhejiang Province, China, to assess the removal mechanisms of fluoroquinolone antibiotics (FQs). PWWTP A uses activated sludge with biocarriers in a moving bed biofilm reactor in anoxic and aerobic units, and PWWTP B uses biological units under anaerobic, aerobic, and anoxic conditions. The wastewater samples and solid samples (sludge and suspended solid matter) were analyzed using solid-phase extraction and ultra-performance liquid chromatography-mass spectrometry. Ofloxacin (OFX) was detected in each stage of PWWTP A, and enrofloxacin and ciprofloxacin were detected in PWWTP B. The concentrations of FQs ranged from 0.32 μg/L to 5.7 mg/L. Although the FQs were largely removed in the biological units (94.5 to 99.9%), large amounts were still discharged in the final effluent (up to 88.0 ± 7.0 μg/L) and dewatered sludge (up to 0.85 ± 0.24 mg/kg). Mass balance analyses of samples from PWWTP A indicated that biodegradation (93.8%) was the major mechanism responsible for the removal of OFX, whereas the contribution of sorption by sludge (0.79%) was less significant, deviating from the findings of most similar studies. Using linear analysis and correlation analysis, we found that the log10 values of the FQ concentration in the sludge were positively related with the log10 values of the equilibrium concentration in water (C w ). These relationships can be described by a Freundlich-like equation. However, these relationships were negative when the C w values were high. Our preliminary explanation is that the equilibrium C w plays an important role in controlling the sorption behavior of FQs in activated sludge.

    Schmitt, R.L.

    The effects of treatment of renal osteopathy with 1.25 (OH)/sub 2/D/sub 3/ was evaluated in 24 chronic hemodialysis patients. The best results of treatment were displayed in patients in whom 1.25 (OH)/sub 2/D/sub 3/ determined only a slow rise in plasma calcium levels. In these patients iPTH, alkaline phosphatase levels, and osteoblast counts in bone biopsies were initially high. Definite improvement of bone resorption was found on X-ray examination. In contrast in patients with low iPTH, low alkaline phosphatase levels, and low osteoblast counts, administration of 1.25 (OH)/sub 2/D/sub 3/ determined a fast rise of plasma calcium levels. No X-ray modifications could be detected.

The NNSS Disposal Facility has been receiving radioactive waste from the U.S. Department of Energy (DOE) complex since the 1960s, and since 2005 the NNSS Disposal Facility has been receiving radioactive and MLLW for disposal only. In accordance with the Resource Conservation and Recovery Act (RCRA), all mixed waste must meet land disposal restrictions (LDRs) prior to disposal. Compliance with LDRs is attained through treatment of the waste to mitigate the characteristics of the listed waste hazard. Presently, most generators utilize commercial capacity for waste treatment prior to shipment to the NNSS Disposal Facility. The objectives of this evaluation are to provide a conceptual study of waste treatment needs (i.e., demand), identify potential waste treatment technologies to meet demand, and analyze implementation considerations for initiating MLLW treatment capacity at the NNSS Disposal Facility. A review of DOE complex waste generation forecast data indicates that current and future Departmental demand for mixed waste treatment capacity will remain steady and strong. Analysis and screening of over 30 treatment technologies narrowed the field of treatment technologies to four: • Macroencapsulation • Stabilization/microencapsulation • Sort and segregation • Bench-scale mercury amalgamation The analysis of treatment technologies also considered existing permits, current the NNSS Disposal Facility infrastructure such as utilities and procedures, and past experiences such as green-light and red-light lessons learned. A schedule duration estimate has been developed for permitting, design, and construction of onsite treatment capability at the NNSS Disposal Facility. Treatment capability can be ready in 20 months.

Methods: A retrospective longitudinal naturalistic study design was used. Data were collected from the database of a tertiary psychiatric center covering the years 2010–2014. Included were bipolar patients who had never been exposed to lithium and had lithium started, and who had PTH, and total and ionized calcium levels available before and during lithium treatment. Paired t-tests were used to analyze changes in PTH and calcium levels. Linear regressions were performed, with mean lithium level and duration of lithium exposure as independent variables and change in PTH levels as dependent variable. Results: A total 31 patients were included. The mean duration of lithium treatment was 18.6±11.4 months. PTH levels significantly increased during lithium treatment (+13.55±14.20 pg/mL; the rate of hyperparathyroidism was 12.9%. Neither total nor ionized calcium increased from baseline to follow-up; none of our patients developed hypercalcemia. Linear regressions analyses did not show an effect of duration of lithium exposure or mean lithium level on PTH levels. Conclusion: Lithium-associated stimulation of parathyroid function is more common than assumed to date. Among parameters to be evaluated prior to lithium implementation, calcium and PTH should be added. Keywords: bipolar disorder, follow-up study, lithium

    Conclusions: We suggest that the effectiveness of β-blocker treatment for PVCs in CKD patients was observed in all 25(OHD levels. However, the responsiveness was higher in patients with a normal range of 25(OHD in comparison to patients with deficiency or insufficiency in 25(OHD levels. Whether vitamin D supplementation increases the efficacy of beta-blocker mediated suppression of PVCs requires further evaluation.

    Sepsis is one of the most common infectious conditions in the neonatal period, and continues as a major source of morbidity and mortality. The aim of this study is to determine serum ischemia-modified albumin (IMA) levels in late-onset neonatal sepsis at the time of diagnosis and after therapy, and to show the meaningful on the follow-up. Also, it is aimed to compare serum IMA levels with serum C-reactive protein (CRP), procalcitonin (PCT) levels and white blood cell count. The study was performed on 33 premature babies with sepsis and 21 healthy premature controls at 7-28 days of age. In the sepsis group, biochemical parameters and blood culture samples were obtained from the blood at the onset and on the fifth day of treatment for each patient. Serum IMA, CRP, PCT and white blood cell count were significantly higher in the sepsis group before treatment when compared with the control group. In addition, the levels of IMA were positively correlated with white blood cell count, CRP and PCT in the sepsis group before treatment. In conclusion, serum IMA levels may be useful in late-onset neonatal sepsis at the time of diagnosis and after therapy. As far as we know this is the first report about the assesment of illness diagnosis and after therapy using serum IMA levels, and further studies are needed to confirm our results in larger groups of patients.

    This study investigated the relationships among an enriched environment, stress levels, and drug addiction. Mice were divided randomly into four treatment groups (n=12 each): enriched environment without restraint stress (EN), standard environment without restraint stress (SN), enriched environment with restraint stress (ES), and standard environment with restraint stress (SS). Mice were reared in the respective environment for 45 days. Then, the ES and SS groups were subjected to restraint stress daily (2 h/day) for 14 days, whereas the EN and SN groups were not subjected to restraint stress during this stage. The stress levels of all mice were tested in the elevated plus maze immediately after exposure to restraint stress. After the 2-week stress testing period, mice were administered acute or chronic morphine (5 mg/kg) treatment for 7 days. Then, after a 7-day withdrawal period, the mice were injected with saline (1 ml/kg) or morphine (5 mg/kg) daily for 2 days to observe locomotor activity. The results indicated that the enriched environment reduced the stress and locomotor activity induced by acute morphine administration or saline after chronic morphine treatment. However, the enriched environment did not significantly inhibit locomotor activity induced by morphine challenge. In addition, the stress level did not mediate the effect of the enriched environment on drug-induced locomotor activity after acute or chronic morphine treatment.

    Highlights: • E2 affects not only estrogen-receptor α positive breast cells but also negative ones. • 100 nM E2 treatment affects breast cells proliferation, migration. • 100 nM E2 treatment functions in an estrogen-receptor α-independent way. • E2 treatment decreases MALAT-1 RNA level by post-transcriptional regulation. - Abstract: Breast cancer cells, which express estrogen receptor α (ERα), respond to estrogen in a concentration dependent fashion, resulting in proliferation or apoptosis. But breast cancer cells without ERα show no effect on low concentration of estrogen treatment. Proliferation, migration and invasion of MCF10a, MCF7 and MB231 cells treated with low (1 nM) or high (100 nM) dose of 17β-Estradiol (E2) was performed. We identified the effects of E2 on these breast cell lines, and looked for the difference in the presence and absence of ERα. Specifically, we looked for the changes of long non-coding RNA metastasis associated lung adenocarcinoma transcript 1 (MALAT-1), which is found extensively and highly expressed in several kinds of tumor cells, including breast carcinoma. It was observed that proliferation, migration and invasion of breast cells were greatly affected by high concentration E2 treatment and were not affected by low concentration E2 treatment in an ERα independent way. We found that the high concentration E2 treatment largely decreased MALAT-1 RNA level. Interestingly, MALAT-1 decreasing by knocking down showed similar effects on proliferation, migration and invasion. E2 treatment affects breast tumor or non-tumor cells proliferation, migration and invasion in an ERα -independent, but a dose-dependent way by decreasing the MALAT-1 RNA level.

    OBJECTIVE Salsalate is a nonacetylated salicylate that lowers glucose levels in people with type 2 diabetes (T2D). Here we examined whether salsalate also lowered serum-protein-bound levels of early and advanced glycation end products (AGEs) that have been implicated in diabetic vascular complications. RESEARCH DESIGN AND METHODS Participants were from the Targeting Inflammation Using Salsalate for Type 2 Diabetes (TINSAL-T2D) study, which examined the impact of salsalate treatment on hemoglobin A1c (HbA1c) and a wide variety of other parameters. One hundred eighteen participants received salsalate, 3.5 g/day for 48 weeks, and 109 received placebo. Early glycation product levels (HbA1c and fructoselysine [measured as furosine]) and AGE levels (glyoxal and methylglyoxal hydroimidazolones [G-(1)H, MG-(1)H], carboxymethyllysine [CML], carboxyethyllysine [CEL], pentosidine) were measured in patient serum samples. RESULTS Forty-eight weeks of salsalate treatment lowered levels of HbA1c and serum furosine (P glycation factors. Pentosidine level changes were unrelated to changes in levels of renal function, inflammation, or cytokines. CONCLUSIONS Salsalate therapy was associated with a reduction in early but not late glycation end products. There was a paradoxical increase in serum pentosidine levels suggestive of an increase in oxidative stress or decreased clearance of pentosidine precursor.

  10. Influence of prelay treatment and dietary protein level on the reproductive performance of White Leghorn hens.

    Two experiments were undertaken to study the influence of prelay diet treatment on subsequent laying performance. Feeding either a conventional laying or growing diet or diets containing essentially only wheat bran from 18 to 21 wk resulted in little grower diet carryover effect beyond 24 wk of age, although the wheat bran diets resulted in a marked drop in body weight of the pullets during the prelay treatment. Similar performance was noted for pullets in a second experiment in which prelay treatments consisted of feeding just corn or wheat bran from 18 to 20 wk of age. In interpreting the results of the present study, it is important to consider the fact that "mature pullet weights" were obtained before the prelay diet treatments were employed. Where prelay diet treatments have had significant effects on laying house performance, in most cases, immature or underweight pullets were involved. Feeding hens low-protein diets (13 versus 17%) from 20 to 44 wk of age resulted in similar egg production; however, egg weight and thus egg mass were slightly reduced with the lower protein diet. There was no laying by growing treatment interaction. The importance of good pullet weight at the start of the production cycle and the subsequent performance of such pullets fed low-protein diets is discussed.

    Although Nucleos(t)ide analogue therapy is thought to suppress chronic hepatitis B(CHB) via regulation of inflammatory cytokines/chemokines, the mechanism is still unclear. In this study, serum cytokine/chemokine levels were measured in CHB patients treated with entecavir, and the association with antiviral response was analyzed. Seventy-eight Japanese patients with CHB were enrolled, and serum cytokine/chemokine levels were measured at baseline and at 12, 24, and 48 weeks of entecavir treatment using the MULTIPLEX kit. Antiviral response to entecavir treatment was significantly associated with HBsAg titer and serum interferon-gamma-inducible protein 10(IP-10) level (12w) (P=0.0002; OR=0.020 [0.002-0.156], P=0.003; OR=0.042 [0.005-0.336], respectively). HBe-positive patients whose serum macrophage-derived chemokine (MDC) level was lower (<582.83 pg/ml) and IP-10 level was higher (1323.13 pg/ml≤) achieved HBeAg loss earlier than remained HBeAg-positive patients (P=0.044). HBsAg reduction by entecavir treatment was significantly associated with higher initial tumor necrosis factor alpha(TNFα) level (15.20 pg/ml≤) and higher ALT level (73 IU/L≤) (P=0.009; OR=18.460 [2.044-166.709], P=0.022; OR=7.709 [1.341-44.327], respectively). Results of the present study indicate that changes in cytokine/chemokine levels following entecavir therapy are associated with response to antiviral therapy in CHB patients. Monitoring of serum cytokine/chemokine levels could be useful for predicting reduction of HBV DNA and HBsAg and HBe seroconversion.

    Porphyromonas gingivalis has been implicated as an etiologic agent of rheumatoid arthritis (RA) because of the expression of peptidylarginine deiminase. The present study evaluates whether periodontal treatment may affect serum antibodies to P. gingivalis and citrulline levels in relation to disease activity of RA. Fifty-five patients with RA were randomly assigned to receive oral hygiene instruction and supragingival scaling (treatment group, n = 26) or no periodontal treatment (control group, n = 29). Periodontal and rheumatologic parameters and serum levels of cytokine and inflammatory markers citrulline and immunoglobulin (Ig)G to P. gingivalis were examined at baseline and 8 weeks later. Both groups did not differ statistically in any parameters except percentage of sites with probing depth and clinical attachment level ≥ 4 mm at baseline. The treatment group exhibited a significantly greater decrease in disease activity score including 28 joints using C-reactive protein (DAS28-CRP) (P = 0.02), serum levels of IgG to P. gingivalis hemin binding protein (HBP)35 (P = 0.04), and citrulline (P = 0.02) than the control group. Serum levels of IgG to P. gingivalis HBP35 were significantly correlated positively with those of anti-cyclic citrullinated peptide antibodies (P = 0.0002). The same correlation was obtained between serum levels of IgG to P. gingivalis-sonicated extracts and those of rheumatoid factor (P = 0.02). These results suggest that supragingival scaling decreases DAS28-CRP and serum levels of IgG to P. gingivalis HBP35 and citrulline in patients with RA. These observations may reflect a role of P. gingivalis in the protein citrullination, which is related to the pathogenesis of RA.

    2008-01-01

    We recruited 46 adult patients affected by disturbing tinnitus lasting for at least 3 years. All were treated with a combined counseling protocol constituting hypnotherapeutic and muscle relaxation techniques. We randomly assigned 26 patients to the group receiving low-level laser stimulation treatment and 20 to the placebo group. The laser power was 5 mV and the wavelength 650 nm. The irradiation lasted 20 minutes daily for 3 months. The Tinnitus Handicap Inventory (THI) questionnaire was submitted at the beginning and at the end of treatment. The THI scores improved in the entire sample after treatment but more significantly in the group receiving low-level laser stimulation. From the point of view of clinical classification, approximately 61% of irradiated patients had tinnitus severity decreased by one class, in comparison to 35% of the placebo group.

    A new method of treating electronic energy level transitions as well as linking ionization to electronic energy levels is proposed following the particle-based chemistry model of Bird. Although the use of electronic energy levels and ionization reactions in DSMC are not new ideas, the current method of selecting what level to transition to, how to reproduce transition rates, and the linking of the electronic energy levels to ionization are, to the author s knowledge, novel concepts. The resulting equilibrium temperatures are shown to remain constant, and the electronic energy level distributions are shown to reproduce the Boltzmann distribution. The electronic energy level transition rates and ionization rates due to electron impacts are shown to reproduce theoretical and measured rates. The rates due to heavy particle impacts, while not as favorable as the electron impact rates, compare favorably to values from the literature. Thus, these new extensions to the particle-based chemistry model of Bird provide an accurate method for predicting electronic energy level transition and ionization rates in gases.

    The aim of this study was to evaluate the acute and late effects of irradiation in 56 patients with stage I and II testicular seminomas. A retrospective study of patients` records was performed paying attention to the acute and late toxicity of radiation in relation to treatment fields and radiation doses. Treatment groups were compared using {chi}{sup 2}-test. Mild to moderate nausea and/or vomiting was seen in 66% of patients and occurred equally independent of the treatment volume or radiation dose. Increased bowel frequency was seen in 59% and was more common when a larger treatment volume was used. Skin reactions increased with increase in treatment volume and dose (p=0.046). Severe late complications were recorded in two patients (myocardial damage - 1/4 at risk, duodenal ulcer - 1/56 at risk). These could not be attributed solely to the irradiation as other contributing factors might play a role. Overall the data suggest that the risk of major posttreatment morbidity is minimal for patients with testicular seminoma treated with postoperative radiotherapy. (orig.).

    Adherence at the earliest stages of treatment is likely to be influenced by prior illness trajectories and future expectations, best captured (and addressed) before treatment begins. We examined the influence of illness trajectories and treatment expectations on psychosocial readiness to start antiretroviral therapy (ART) in Jinja, Uganda. In-depth interviews were conducted between October 2005 and April 2006 with 41 members of an AIDS support organisation on their first day of treatment. Transcribed texts were translated, coded and analysed thematically using NVIVO-7 software. Results indicated that acute fear of death and progressive withdrawal from social, economic and sexual roles narrowed focus on survival, while efficacy-enhancing experiences with septrin prophylaxis and trust in counsellors reinforced belief in HIV diagnosis and importance of adherence. Most enjoyed supportive home environments after disclosing their serostatus. Lack of money for food and transport was anticipated as the main barriers to future adherence, particularly among women. Integrating strong counselling support with ART provision helped channel the power of shared illness experience into positive motivation to adhere at the onset of treatment.

    We sought to investigate the association of preoperative fibrinogen levels with clinicopathologic outcomes after surgical treatment of nonmetastatic renal cell carcinoma. We reviewed the records of 1511 patients who had their fibrinogen levels measured preceding surgery. The associations between preoperative fibrinogen level and risk of adverse clinicopathologic outcomes were tested using the multivariate logistic regression and multiple Cox-proportional hazards model, respectively. Based on plasma fibrinogen levels, we stratified the patients into 2 groups with a cut-off value of 328  mg/dL. Kaplan-Meier analysis showed significantly inferior survival outcomes in progression-free (P fibrinogen level (≥328  mg/dL) was significantly related to a higher Fuhrman grade (hazard ratio [HR] 1.374, P = 0.006) and a larger tumor size (≥7  cm) (HR 2.364, P fibrinogen level is a significant predictor for poor disease progression (HR 1.857, P fibrinogen levels were significantly associated with poor pathological features and worse survival outcomes in patients with nonmetastatic renal cell carcinoma after surgical treatment. Further evaluations such as prospective randomized trials are needed to understand the underlying mechanism for these associations.

    Full Text Available Objective: To assess whether non-surgical periodontal treatment is associated with changes in serological markers of systemic inflammation.Materials and Methods: Thirty-five systemically healthy subjects with severe generalized periodontitis meeting the inclusion criteria participated in a four-month single blind interventional trial of which thirty-two completed the study. Periodontal parameters andinflammatory markers [C-reactive protein (CRP and plasma fibrinogen] and also the white blood cell count (WBC were evaluated prior to and four months after delivery of intensive non-surgical periodontal therapy with simultaneous lavage of chlorhexidine0.1% from the tip of the ultrasonic instrument into the pockets.Results: Significant differences in serum CRP levels were observed four months after treatment compared to the baseline (1.85, SD=1.93 vs 2.46, SD=2.32, respectively,P<0.0001. Periodontal treatment also resulted in a significant difference in WBC and neutrophilcounts compared to the baseline (P<0.0001. The reduction in fibrinogen levels was not significant at the end of the research period. Significant improvement in the pocket probing depth and clinical attachment level for pockets with initially 4-6 mm and thenmore than 7 mm depth was observed. Changes in plaque and bleeding scores were also statistically significant (82.75 vs. 35.84 and 19.03 vs. 1.81, respectively.Conclusion: Periodontal treatment is effective in reducing CRP levels and white blood cell count, while fibrinogen levels are not influenced by periodontal therapy. Periodontal treatment may therefore decrease the systemic inflammatory burden in patients with advanced periodontitis.

    Ubiquinone (coenzyme Q10, Q10) represents an endogenously synthesized lipid-soluble antioxidant which is crucial for cellular energy production but is diminished with age and under the influence of external stress factors in human skin. Here, it is shown that topical Q10 treatment is beneficial with regard to effective Q10 replenishment, augmentation of cellular energy metabolism, and antioxidant effects. Application of Q10-containing formulas significantly increased the levels of this quinone on the skin surface. In the deeper layers of the epidermis the ubiquinone level was significantly augmented indicating effective supplementation. Concurrent elevation of ubiquinol levels suggested metabolic transformation of ubiquinone resulting from increased energy metabolism. Incubation of cultured human keratinocytes with Q10 concentrations equivalent to treated skin showed a significant augmentation of energy metabolism. Moreover, the results demonstrated that stressed skin benefits from the topical Q10 treatment by reduction of free radicals and an increase in antioxidant capacity.

    Oral mucositis is a debilitating and dose limiting side effect of oncotherapy in cancer patients. Low Level Laser Therapy (LLLT) is a promising new intervention for the treatment of oral mucositis. Aims and objectives: 1. Perform a systematic review of available literature on the therapeutic effect of LLLT on established oral mucositis. 2. Formulate recommendations for future studies based on results of review. Methods: Electronic search oflow level laser therapy in the treatment of oral mucositis was conducted and eligible studies reviewed. Results: Four studies met the inclusion criteria and were analyzed. A total of 109 patients were included, 59 of which received LLLT as a therapeutic measure. An overall success rate of 81.4% success rate was reported in regard to OM. Conclusion: The review demonstrated the positive therapeutic effect of LLLT on oral mucositis. However, the need for future studies with standardized reporting of parameters and methods is needed to increase the level of evidence of this intervention.

    Diabetes mellitus (DM), non-alcoholic fatty liver (NAFL), and obesity are associated with elevated branched-chain amino acid (BCAA) levels, but the mechanism and significance of this has not been elucidated. Eighty-four subjects were enrolled including 43 with DM. Serum BCAA levels were positively correlated with waist-hip ratio and ALT. Serum BCAA levels in subjects with DM were higher than non-DM and those in subjects with NAFL were also higher than non-NAFL. Treatment with pioglitazone and alogliptin (19 of 43 DM subjects) improved serum haemoglobin A1c and decreased BCAA levels. The decrease in BCAAs with improved glucose metabolism suggests that abnormal glucose metabolism is also a factor in elevated BCAA levels.

Nonsuppressed HIV viral load is associated with drug resistance, increased morbidity and mortality, and a higher risk of person-to-person HIV transmission. For HIV-infected individuals who are failing HIV treatment due to nonadherence, becoming adherent is a life-saving behavior change. However, overcoming nonadherence is one of the most daunting challenges in the successful management of HIV disease. The purpose of this paper is to provide clinicians with a better understanding of nonadherence to ARV treatment and to review the various factors that have been associated with either adherence or nonadherence. Strategies are presented that may help the nonadherent individual become ready to take HIV medications as prescribed.Keywords: noncompliance, treatment failure, AIDS

    The evaluation and comparison of proposed thermal treatment systems for mixed wastes can be expedited by tests in which the radioactive components of the wastes are replaced by surrogate materials chosen to mimic, as far as is possible, the chemical and physical properties of the radioactive materials of concern. In this work, sponsored by the Mixed Waste Integrated Project of the US Department of Energy, the authors have examined reported experience with such surrogates and suggest a simplified standard list of materials for use in tests of thermal treatment systems. The chief radioactive nuclides of concern in the treatment of mixed wastes are {sup 239}Pu, {sup 238}U, {sup 235}U, {sup 137}Cs, {sup 103}Ru, {sup 99}Tc, and {sup 90}Sr. These nuclides are largely by-products of uranium enrichment, reactor fuel reprocessing, and weapons program activities. Cs, Ru, and Sr all have stable isotopes that can be used as perfect surrogates for the radioactive forms. Technetium exists only in radioactive form, as do plutonium and uranium. If one wishes to preclude radioactive contamination of the thermal treatment system under trial burn, surrogate elements must be chosen for these three. For technetium, the authors suggest the use of natural ruthenium, and for both plutonium and uranium, they recommend cerium. The seven radionuclides listed can therefore be simulated by a surrogate package containing stable isotopes of ruthenium, strontium, cesium, and cerium.

    Vaginitis is the most common female infectious disease. Females suffering from this disorder are annually increasing in number. There are a lot of modalities of treatment of vaginitis, but because of drug allergy and microbe's stability to drug the treatment of vaginitis is difficult. Our study compares the efficacy of laser-therapy with drug therapy in the treatment of non-specific vaginitis and vaginal candidiasis. Thirty women reci4eed the LLLT by local action with antiseptic liquid daily during ten days, 20 women received metronidazole and fluconozole and vaginal application of metronidazole. The results suggest that local laser-therapy is able to remove sights of vaginitis more efficiently and faster than drug therapy. Repair of normal vaginal microflora, which is the best indicator of recovery, was significantly at a faster rate in laser-therapy group. There were no report of adverse reaction with vaginal laser- therapy, whereas there were women on drug therapy who reported side effects. In conclusion, vaginal aser-therapy with antiseptic liquid is a suitable, effective, safe and chip alternative to drug therapy in the treatment of vaginitis.

  1. Treatment response in Kawasaki disease is associated with sialylation levels of endogenous but not therapeutic intravenous immunoglobulin G.

    Directory of Open Access Journals (Sweden)

    Full Text Available OBJECTIVES: Although intravenous immunoglobulin (IVIG is highly effective in Kawasaki disease (KD, mechanisms are not understood and 10-20% of patients are treatment-resistant, manifesting a higher rate of coronary artery aneurysms. Murine models suggest that α2-6-linked sialic acid (α2-6Sia content of IVIG is critical for suppressing inflammation. However, pro-inflammatory states also up-regulate endogenous levels of β-galactoside:α2-6 sialyltransferase-I (ST6Gal-I, the enzyme that catalyzes addition of α2-6Sias to N-glycans. We asked whether IVIG failures correlated with levels of α2-6Sia on infused IVIG or on the patient's own endogenous IgG. METHODS: We quantified levels of α2-6Sia in infused IVIG and endogenous IgG from 10 IVIG-responsive and 10 resistant KD subjects using multiple approaches. Transcript levels of ST6GAL1, in patient whole blood and B cell lines were evaluated by RT-PCR. Plasma soluble (sST6Gal-I levels were measured by ELISA. RESULTS: There was no consistent difference in median sialylation levels of infused IVIG between groups. However, α2-6Sia levels in endogenous IgG, ST6GAL1 transcript levels, and ST6Gal-I protein in serum from IVIG-resistant KD subjects were lower than in responsive subjects at both pre-treatment and one-year time points (p <0.001, respectively. CONCLUSIONS: Our data indicate sialylation levels of therapeutic IVIG are unrelated to treatment response in KD. Rather, lower sialylation of endogenous IgG and lower blood levels of ST6GALI mRNA and ST6Gal-I enzyme predict therapy resistance. These differences were stable over time, suggesting a genetic basis. Because IVIG-resistance increases risk of coronary artery aneurysms, our findings have important implications for the identification and treatment of such individuals.

    Introduction: LLLT in oral cavity believed to reduce pain after endodontic surgery and wisdom tooth removal, to accelerate wound healing and to have an anti-inflammatory and regenerative effect. The aim of this systematic review therefore was to assess the proof available for the efficacy of low-level laser treatment in reducing pain and swelling after endodontic surgery. Methods: The PubMed service of the U.S. National Library of Medicine was searched with applicable search strategies. No language restriction was applied. The last electronic search was accomplished on August 31, 2015. All randomized clinical trials on the efficiency of low-level laser treatment in reducing pain and swelling after endodontic surgery was considered for the Meta-analysis. Quality consideration of the included randomized clinical trials was appraised according to CONSORT guidelines. Results: Only two randomized clinical trials were attained. These studies clarified that laser treatment could reduce pain and swelling, but the results were not significant. Conclusions: Low-level laser therapy can be advantageous for the reduction of postoperative pain but there is no strong confirmation for its efficiency. Its clinical utility and applicability relating to endodontic surgery, Along with the optimal energy dosage and the number of laser treatments needed after surgery, still, demand further research and experiment.

  3. Heparanase Levels Are Elevated in the Plasma of Pediatric Cancer Patients and Correlate with Response to Anticancer Treatment

    Full Text Available Heparanase is an endoglycosidase that specifically cleaves heparan sulfate (HS side chains of heparan sulfate proteoglycans, the major proteoglycan in the extracellular matrix (ECM and cell surfaces. Heparanase upregulation was documented in an increasing number of primary human tumors, correlating with reduced postoperative survival rate and enhanced tumor angiogenesis. The purpose of the current study was to determine heparanase levels in blood samples collected from pediatric cancer patients using an ELISA method. Heparanase levels were elevated four-fold in the plasma of cancer patients compared with healthy controls (664 ± 143 vs 163 ± 18 pg/ml, respectively. Evaluating plasma samples following anticancer therapy revealed reduced heparanase levels (664 ± 143 vs 429 ± 82 pg/ml, differences that are statistically highly significant (P = .0048. Of the 55 patients with complete remission (CR or very good partial remission (VGPR at restaging, 41 (74.5% had lower heparanase amounts, whereas 14 patients (25.5% had similar or higher amounts of plasma heparanase. All nine patients with stable or advancing disease had similar or elevated levels of heparanase on restaging. The results show that heparanase levels are elevated in the plasma of pediatric cancer patients and closely correlate with treatment responsiveness, indicating that heparanase levels can be used to diagnose and monitor patient's response to anticancer treatment.

    Background Periodontal disease is closely related to type 2 diabetes and is an important complication of diabetes.This study aimed to investigate the effect of periodontal treatment on levels of blood glucose (Glu) and glycosylated hemoglobin (HbA1c) among elderly patients with type 2 diabetes and periodontal disease.Methods A total of 107 elderly patients with type 2 diabetes and periodontal disease were selected and divided into two groups according to their HbA1c levels. Group A was a well-controlled diabetic group and group B was uncontrolled.Their probing depth (PD), attachment loss (AL), the value of Glu and HbA1c were analyzed before periodontal treatment and 4 months later.Results There was a significant difference in periodontal condition between groups A and B (P <0.01). The periodontal condition for both groups was significantly (P<0.01) improved after periodontal therapy. The effect of treatment in group A was more pronounced than group B, and the difference was significant (P <0.01). After the periodontal treatment, Glu and HbA1c were reduced significantly in both groups (P <0.05).Conclusions Periodontal condition is related to the control of Glu level among elderly patients with type 2 diabetes and periodontal disease. Periodontal treatment can effectively reduce the level of Glu and HbA1c as well as improve the periodontal condition in elderly type-2 diabetes patients with periodontal disease.

    Studying host parasite interactions and their implications for evolution and ecology recently received increasing attention, particularly with regard to host physiology and immunity. Here we assess variation of urinary neopterin (uNEO), a marker of cellular immune activation and iummunosenescence, in response to age and anthelmintic treatment in semi-free ranging Barbary macaques (Macaca sylvanus). Urinary NEO levels were measured via enzyme-immunoassay from 179 urine samples of 43 individuals between 5–29 years of age. Efficiency of treatment was assessed by Mc Master flotation on repeated faecal samples, including 18 untreated individuals as control group. We used linear mixed models with age and parasite status as main effects, controlling for sex and physical condition, assessed through urinary C-Peptide-levels, with social group and ID as random factors. Urinary NEO levels significantly increased with age, suggesting that changes in aging Barbary macaque immune responses are consistent with immunosenescence described in human and nonhuman primates and can be detected via uNEO measurements. Anthelmintic treatment, however, had no influence on uNEO levels, potentially due to quick reinfections or attenuated immune responses in repeated infections. We conclude that uNEO is a potential non-invasive marker for immune function and particularly immunosenescence in wildlife. PMID:28155915

    Private sector capacity for treatment, storage, and disposal (TSD) of various categories of radioactive waste has been researched and reviewed for the Idaho National Engineering Laboratory (INEL) by Lockheed Idaho Technologies Company, the primary contractor for the INEL. The purpose of this document is to provide assistance to the INEL and other US Department of Energy (DOE) sites in determining if private sector capabilities exist for those waste streams that currently cannot be handled either on site or within the DOE complex. The survey of private sector vendors was limited to vendors currently capable of, or expected within the next five years to be able to perform one or more of the following services: low-level waste (LLW) volume reduction, storage, or disposal; mixed LLW treatment, storage, or disposal; alpha-contaminated mixed LLW treatment; LLW decontamination for recycling, reclamation, or reuse; laundering of radioactively-contaminated laundry and/or respirators; mixed LLW treatability studies; mixed LLW treatment technology development. Section 2.0 of this report will identify the approach used to modify vendor information from previous revisions of this report. It will also illustrate the methodology used to identify any additional companies. Section 3.0 will identify, by service, specific vendor capabilities and capacities. Because this document will be used to identify private sector vendors that may be able to handle DOE LLW and mixed LLW streams, it was decided that current DOE capabilities should also be identified. This would encourage cooperation between DOE sites and the various states and, in some instances, may result in a more cost-effective alternative to privatization. The DOE complex has approximately 35 sites that generate the majority of both LLW and mixed LLW. Section 4.0 will identify these sites by Operations Office, and their associated LLW and mixed LLW TSD units.

    The cost of bringing DOE into compliance with the Federal Facilities Compliance Act may be dramatically reduced if the private sector treats DOE mixed low level waste. If the DOE clearly defines this market by using national procurement contracts, the private sector will be able to decide if investing in DOE waste treatment contracts is good business. DOE can structure the mixed waste treatment market to influence the profitability of the contracts and to influence the quality of private sector responses. National procurement contracts will incorporate advice from the private sector so that issues of concern to industry are adequately incorporated.

    Full Text Available An experiment was carried out using Buffalos to study the transfer of aflatoxins B1 (AFB1 from feeds to Mozzarella cheese. Two groups of four buffalos were assigned to two AFB1 doses: 100 and 150 μg/day. Total daily milk produced by each animal was individually collected at -2, 1, 3, 5 and +2 days, during and after experimental treatment, and separately, daily processed into Mozzarella cheese. The mean M1 and B1 aflatoxin content was significantly affected by the AFB1 doses. The AFM1 increased linearly from the first day of treatment to the last one in both groups, but in that treated with low dose the concentration was 4 time lower.

    To investigate the safety, efficacy, and acceptability of misoprostol versus manual vacuum aspiration (MVA) for treatment of incomplete abortion. A prospective open-label randomised trial. Kagera Regional Hospital, Bukoba, Tanzania. Three hundred women with a clinical diagnosis of incomplete abortion and a uterine size misoprostol or MVA. If abortion was clinically complete at 7-day follow up, the woman was released from the study. If it was still incomplete, the woman was offered the choice of an additional 1-week follow up or immediate MVA. Cases still incomplete after a further week were offered MVA. Incidence of successful abortion (success defined as no secondary surgical intervention provided), incidence of adverse effects, patient satisfaction. Success was very high in both arms (misoprostol: 99%; MVA: 100%; difference not significant). Most adverse effects were higher in the misoprostol arm, although the mean pain score was higher in the MVA arm (3.0 versus 3.5; P misoprostol (75%) than with MVA (55%, P = 0.001), and a higher proportion of women in the misoprostol arm said that they would recommend the treatment to a friend (95% versus 75%, P Misoprostol is as effective as MVA at treating incomplete abortion at uterine size of misoprostol appears higher. Given the many practical advantages of misoprostol over MVA in low-resource settings, misoprostol should be more widely available for treatment of incomplete abortion in the developing world.

    Fats, oils, and grease from restaurants and homes can congeal in sewers and result in damaging runoff into rivers and streams. A growing number of food service establishments are now producing increasing amounts of a specific grease product called brown grease, which is sticky and difficult to remove. Regulations now require haulers to remove the waste and dispose of it. However, many local treatment plants cannot accept or dispose of the amounts of grease currently being produced. A total of volume of 3 to 10 billion gallons per year of contaminated water have been accidentally discharged from sanitary sewers as a result of brown grease accumulations. This paper provided details of the EcoPlus Final Treatment Facility, which can be set up at waste water treatment plants and is able to process brown grease and discharge supernatant water from its process back into city sewers. The EcoPlus process produces 2 waste streams: (1) a low strength aqueous solution that can be disposed of in a sanitary sewer tap; and (2) a granular material that can be disposed of in a landfill for use as a soil conditioner. It was concluded that the granular material can also be used facilitate the incineration of sewage sludge, or burned as an alternative green fuel for power generation. 4 figs.

    The time and motion study was developed to look at time-related aspects of the technologies and systems studied in the Integrated Thermal Treatment Systems (ITTS) and Integrated Nonthermal Treatment Systems (INTS) studies. The INTS and ITTS studies combined technologies into systems and subsystems for evaluation. The system approach provides DOE a method of measuring advantages and disadvantages of the many technologies currently being researched. For example, technologies which are more likely to create secondary waste or require extensive pretreatment handling may be less desirable than technologies which require less support from other processes. The time and motion study was designed to address the time element in the INTS and ITTS systems studies. Previous studies have focused on material balance, cost, technical effectiveness, regulatory issues, community acceptance, and operability. This study looks at system dynamics by estimating the treatment time required for a unit of waste, from receipt to certification for shipping. Labor estimates are also developed, based on the time required to do each task for each process. This focus on time highlights critical path processes and potential bottlenecks in the INTS and ITTS systems.

    2001-04-01

    Memory tends to be better for emotionally arousing information than for neutral information. Evidence from animal studies indicates that corticosteroids may be necessary for this memory enhancement to occur. We extend these findings to human memory performance. Following administration of cortisol (20 mg) or placebo, participants were exposed to pictures varying in emotional arousal. Incidental memory for the pictures was assessed one week later. We show that elevated cortisol levels during memory encoding enhances the long-term recall performance of emotionally arousing pictures relative to neutral pictures. These results extend previous work on corticosteroid enhancement of memory and suggest that high cortisol levels during arousing events result in enhanced memory in humans.

    Around 25% of patients with systemic lupus erythematosus (SLE) could be refractory to conventional therapies. P-glycoprotein expression on cell surface has been implied on drug resistance, however, to date, it is unknown if P-gp serum levels are associated with SLE disease activity. Evaluate the association of serum P-gp levels and SLE with disease activity despite treatment. A cross-sectional study was conducted on 93 female SLE patients, all receiving glucocorticoids at stable doses for the previous 6 months before to baseline. SLE patients were classified into two groups: (a) patients with active disease [SLE disease activity index (SLEDAI) ≥ 3] despite treatment, and (b) patients with inactive disease (SLEDAI P-gp, anti-DNA, and both anti-nucleosome antibody levels were measured using ELISA. Active-SLE patients despite treatment had higher P-gp levels compared with inactive-SLE after treatment (78.02 ng/mL ± 114.11 vs. 33.75 ng/mL ± 41.11; p = 0.018) or versus reference group subjects (30.56 ng/mL ± 28.92; p = 0.011). P-gp levels correlated with the scores of SLEDAI (r = 0.26; p = 0.01), Mexican-SLEDAI (MEX-SLEDAI) (r = 0.32; p = 0.002), SLICC/ACR damage index (r = 0.47; p p = 0.001). In the multivariate model, the high P-gp levels were associated with SLICC/ACR score (p = 0.001), and SLEDAI score (p = 0.014). Our findings support a relationship between serum P-gp levels and SLE with disease activity despite treatment, but it requires further validation in longitudinal studies.

    The SCE base level frequency and SCE levels induced by far-UV (254 nm) treatment of cells in early G/sub 1/ and early S phases of the cell cycle were significantly higher in leukocytes from heroin addicts as compared to controls. The increased SCE levels in addicts was greatest at base level and smallest after UV irradiation of cells in S phase. These results corrobate and extend our previous findings of increased chromosome damage and reduced DNA-repair synthesis in heroin users. Since opiates do not directly damage DNA, the elevated cytogenetic effects associated with opiate use probably arise from secondary promotional effects related to opiate-mediated alterations in leukocyte metabolism.

    1995-12-31

    Rust Federal Services, under contract to the United States Department of Energy (DOE), Idaho Operations Office, performed a study to develop and evaluate the feasibility of a suggested private sector solution for the treatment of alpha-contaminated low-level mixed waste (ALLMW) stored or produced at the Idaho National Engineering Laboratory (INEL). The feasibility study is an initial step in the potential procurement of privatized treatment services for these wastes. Rust`s derived objective of the feasibility study was to define an optimal treatment system and analyze the feasibility of that system for accomplishing the processing objectives specified by DOE. All aspects of the selected treatment system were addressed in the feasibility study, including technical, regulatory, public involvement, and financial considerations. Two central elements of the study were a technology screening task to select the optimal treatment system and an analysis of the institutional, business, financial, and contractual issues that are likely to accompany the privatization of treatment services for DOE.

    This study aimed to evaluate the safety of antiretroviral treatment interruption (TI) in HIV-infected patients who started treatment based on earlier guidelines, and to identify baseline factors predictive of the time to reach fixed criteria for treatment resumption. Prospective, open-label, multicenter trial. Patients were eligible if they had a CD4 cell count >350/mm(3) and plasma HIV RNA 450/mm(3) and stable plasma HIV RNA <5,000 copies/ml for at least 6 months prior to enrollment. The criteria for ART resumption were a CD4 cell count <300/mm(3) and/or a CDC stage B or C event. 116 patients had received ART for a median of 5.3 years. The median CD4 cell count and plasma HIV RNA values at inclusion were 809/mm(3) and 2.6 log copies/ml, respectively. Median HIV DNA load at inclusion was 2.3 log copies/10(6) peripheral blood mononuclear cells (PBMCs). Thirty-six months after TI, 63.9% of the patients had not yet reached the criteria for ART resumption, and 55.9% of patients had not resumed ART. In Cox multivariable analysis, a high HIV DNA level at TI, a low CD4 nadir, and pre-existing AIDS status were the only significant risk factors for reaching the criteria for ART resumption (hazards ratio: 2.15 (1.02-4.53), 4.59 (1.22-17.24), and 5.74 (1.60-20.56), respectively). Patients who started ART with a CD4 cell count above 350/mm(3) were able to interrupt treatment for long periods without a high absolute risk of either AIDS or severe non-AIDS morbidity/mortality. A high PBMC HIV DNA level at TI was a strong predictor for more rapid treatment resumption.

    To evaluate the rate of immunogenicity induced by adalimumab and its relationship with drug serum levels and clinical responses in patients with noninfectious uveitis. Prospective observational study. Consecutive patients from 1 referral center who initiated treatment with adalimumab for active noninfectious uveitis resistant to conventional therapy. All patients received 40 mg adalimumab every other week. Patients were evaluated clinically and immunologically before and after 4, 8, and 24 weeks of treatment. Clinical evaluation included assessment of changes in visual acuity, degree of inflammation in the anterior chamber and vitreous cavity, central macular thickness, and retinal angiographic leakage. Immunologic evaluation included assessment of serum trough adalimumab and antibodies against adalimumab (AAA) levels and class II HLA typing. Twenty-five patients were enrolled. Overall, 18 of 25 patients (72%) showed a favorable clinical response to adalimumab therapy. Eleven patients (44%) achieved a complete response and 7 (28%) achieved a partial response. However, 7 of 25 patients (28%) were considered nonresponders. Median trough adalimumab serum levels were higher in responders than in nonresponders (P uveitis outcome was observed only in patients with permanent AAA+, which correlated with undetectable adalimumab trough levels (P = 0.014). Treatment of noninfectious uveitis with adalimumab is associated with high rates of favorable clinical response. Overall, adalimumab trough levels were higher in responder patients. Development of permanent AAA was associated with undetectable trough adalimumab levels and worse uveitis outcome. Immunogenicity was more common in patients in whom uveitis was associated with a systemic disease and was not influenced by concomitant immunosuppressors.

    The aim of the present study was to conduct a meta-analysis of randomized controlled trials (RCTs) that investigated the effects of metformin on blood leptin and ghrelin levels in patients with type 2 diabetes mellitus (T2DM). Literature searches were performed using MEDLINE, Cochrane Controlled Trials Registry, and ClinicalTrials.gov, and RCTs that investigated the effects of metformin on blood leptin and ghrelin levels in patients with T2DM were selected. Standardized mean differences (SMDs) and 95 % confidence intervals (CIs) were calculated. Twelve RCTs met the eligibility criteria and were included in the meta-analysis. There was no significant difference in blood leptin between the metformin and control groups (SMD 0.03; 95 % CI -0.35 %, 0.42 %; P = 0.86), although there was a significant difference in blood leptin levels between the metformin group and the group on oral antidiabetic drugs (OADs) other than metformin (SMD -0.39; 95 % CI -0.76 %, -0.01 %; P = 0.04). There were no significant differences in blood ghrelin levels. Metformin treatment was not associated with a decrease in blood leptin levels in patients with T2DM compared with levels in patients in the control group. Moreover, metformin treatment was not associated with increases in blood ghrelin levels compared with the control and other OADs groups. However, blood leptin levels were significantly lower in the metformin compared with the other OADs group. © 2016 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    Objective Human serum paraoxonase (PON1) prevents lipids from peroxidation and functions as an antioxidant mechanism. Malonyldialdehyde (MDA) is the final product of lipid peroxidation and can be used as an indicator of oxidative stress. The aim of this study was to investigate PON1, MDA, and arylesterase (ARY) levels in schizophrenic patients who are taking typical, atypical, or combined (typical and atypical) antipsychotic drug treatment, with respect to those of healthy controls. Methods We evaluated 41 patients (11 taking typical antipsychotics, 19 taking atypical antipsychotics, 11 taking combined anti-psychotics) and 43 healthy controls. Results MDA levels were higher in schizophrenic patients taking typical antipsychotics compared with healthy controls (p=0.001). ARY levels were higher in patients taking atypical antipsychotics compared with healthy controls (p=0.005). PON1 activity was similar in all groups. Conclusion Our results indicate that treatment with typical antipsychotic drugs could be related to increased MDA levels; and antipsychotic medication may increase PON1 levels in schizophrenic patients.

    Chemotherapy-induced alopecia (CIA) is one of the most distressing side effects of antineoplastic chemotherapy for which there is no effective interventional approach. A low-level laser (LLL) device, the HairMax LaserComb®, has been cleared by the FDA to treat androgenetic alopecia. Its effects may be extended to other settings; we have demonstrated that LaserComb treatment induced hair regrowth in a mouse model for alopecia areata. In the current study, we tested whether LLL treatment could promote hair regrowth in a rat model for CIA. Chemotherapy agents cyclophosphamide, etoposide, or a combination of cyclophosphamide and doxorubicin were administered in young rats to induce alopecia, with or without LLL treatment. As expected, 7-10 days later, all the rats developed full body alopecia. However, rats receiving laser treatment regrew hair 5 days earlier than rats receiving chemotherapy alone or sham laser treatment (with the laser turned off). The accelerated hair regrowth in laser-treated rats was confirmed by histology. In addition, LLL treatment did not provide local protection to subcutaneously injected Shay chloroleukemic cells. Taken together, our results demonstrated that LLL treatment significantly accelerated hair regrowth after CIA without compromising the efficacy of chemotherapy in our rat model. Our results suggest that LLL should be explored for the treatment of CIA in clinical trials because LLL devices for home use (such as the HairMax LaserComb®) provide a user-friendly and noninvasive approach that could be translated to increased patient compliance and improved efficacy.

    Frontotemporal dementia (FTD is associated with motor neurone disease (FTD-MND, corticobasal syndrome (CBS and progressive supranuclear palsy syndrome (PSPS. Together, this group of disorders constitutes a major cause of young-onset dementia. One of the three clinical variants of FTD is progressive nonfluent aphasia (PNFA, which is focused on in this study. The steroid hormone progesterone (PROG is known to have an important role as a neurosteroid with potent neuroprotective and promyelination properties. In a case-control study of serum samples (39 FTD, 91 controls, low serum PROG was associated with FTD overall. In subgroup analysis, low PROG levels were significantly associated with FTD-MND and CBS, but not with PSPS or PNFA. PROG levels of >195 pg/ml were significantly correlated with lower disease severity (frontotemporal dementia rating scale for individuals with CBS. In the human neuroblastoma SK-N-MC cell line, exogenous PROG (9300–93,000 pg/ml had a significant effect on overall Tau and nuclear TDP-43 levels, reducing total Tau levels by ∼1.5-fold and increasing nuclear TDP-43 by 1.7- to 2.0-fold. Finally, elevation of plasma PROG to a mean concentration of 5870 pg/ml in an Ala315Thr (A315T TARDBP transgenic mouse model significantly reduced the rate of loss of locomotor control in PROG-treated, compared with placebo, mice. The PROG treatment did not significantly increase survival of the mice, which might be due to the limitation of the transgenic mouse to accurately model TDP-43-mediated neurodegeneration. Together, our clinical, cellular and animal data provide strong evidence that PROG could be a valid therapy for specific related disorders of FTD.

    A number of waste components in US defense high level radioactive wastes (HLW) have proven challenging for current Joule heated ceramic melter (JHCM) operations and have limited the ability to increase waste loadings beyond already realized levels. Many of these "troublesome" waste species cause crystallization in the glass melt that can negatively impact product quality or have a deleterious effect on melter processing. Recent efforts at US Department of Energy laboratories have focused on understanding crystallization behavior within HLW glass melts and investigating approached to mitigate the impacts of crystallization so that increases in waste loading can be realized. Advanced glass formulations have been developed to highlight the unique benefits of next-generation melter technologies such as the Cold Crucible Induction Melter (CCIM). Crystal-tolerant HLW glasses have been investigated to allow sparingly soluble components such as chromium to crystallize in the melter but pass out of the melter before accumulating.

    2015-01-01

    Light transport in periodic waveguides coupled to a two-level atom is investigated. By using optical Bloch equations and a photonic modal formalism, we derive semi-analytical expressions for the scattering matrix of one atom trapped in a periodic waveguide. The derivation is general, as the expressions hold for any periodic photonic or plasmonic waveguides. It provides a basic building block to study collective effects arising from photon-mediated multi-atom interactions in periodic waveguides.

  9. Treatment of germinated wheat to increase levels of GABA and IP6 catalyzed by endogenous enzymes.

    Nagaoka, Hiroyuki

    2005-01-01

    We found that the levels of bioactive products from wheat can be increased dramatically by manipulating germination conditions and taking advantage of the activity of endogenous enzymes. The yield of phytic acid (IP(6)) from wheat germinated in the presence of high, controlled levels of dissolved oxygen (188 +/- 28 mg/100 g wheat) was almost three times greater than that from wheat germinated with no supplemental oxygen (74 +/- 10 mg/100 g wheat). The yield of gamma-aminobutyric acid (GABA) from wheat germinated in the presence of uncontrolled levels of dissolved oxygen was 18 +/- 3 times greater than that from nonsupplemented wheat (1 mg/100 g wheat). The concentration of GABA was much greater in wheat germ than in whole wheat, and the yield of GABA from wheat germ processed with supplemental water (163 +/- 7 mg/100 g wheat germ) was notably greater than that from wheat germ processed with no supplemental water (100 +/- 2 mg/100 g wheat germ). In contrast, IP(6) was more concentrated in wheat bran, and the yield of IP(6) from wheat bran processed with supplemental water (3100 +/- 12 mg/100 g wheat bran) was notably higher than that from wheat bran processed with no supplemental water (2420 +/- 13 mg/100 g wheat bran). We conclude that the large amount of GABA extracted from wheat germ is likely due to high glutamate decarboxylase activity and low aminotransferase activity and that the large amount of IP(6) extracted from wheat bran is likely due to high levels of tyrosinase activity. Our findings indicate that bioactive molecules such as GABA and IP(6) can be successfully mass-produced by taking advantage of endogenous enzymatic activities.

    Full Text Available Abstract Treatment with prostaglandin(PG-E2 is clinically efficient for cervical priming. The aim of this study was to evaluate the impact of PG-E2 on the expression of the progesterone (PR, androgen (AR and glucocorticoid (GR receptors in human uterine cervix in prolonged pregnancy. The study groups were postterm nulliparous women with unripe cervices undergoing cervical priming with PG-E2 before labor induction. Responders (n = 12 who delivered vaginally were compared with non-responders (n = 10, who underwent cesarean section due to failure to progress to the active phase of labor. Controls (n = 18 with vaginal partus at a normal gestational age served as a reference group. Cervical levels of PR-A and PR- B isoforms, AR and GR, serum levels of their ligands and sex hormone-binding globulin (SHBG were quantified. The responder group displayed lower total PR-AB and AR protein levels as compared to non-responders, and lower PR-B and AR protein levels as compared to controls. In addition, the PR mRNA level was lower in responders as compared to non-responders. The GR protein level did not differ between the groups. We conclude that successful PG-E2 priming was followed by a progesterone and androgen withdrawal at the receptor level in the uterine cervix.

    Background data of polychlorinated dibenzodioxin and dibenzofuran (PCDD/Fs) emissions from the incineration sector in Colombia are presented. Monitoring was carried out during a two-year period, 2003-2005. Twelve plants were sampled for stack gas emissions of dioxins and total solid particulate (TSP). Additionally, PCDD/Fs in several fly ash samples were analyzed. Most incinerators burned industrial refuse materials and medical residues. A wide range of PCDD/Fs emission levels were found. In particular, levels ranging from 6.9 to 343.8 ng I-TEQ/N m(3) were determined in plants without any air pollution control system (APCS). In contrast, 0.5-39.2 ng I-TEQ/N m(3) levels were found in plants with APCS while 8.5-67.5 ng I-TEQ/g were measured in fly ash samples. TSP values ranged from 14 to 448 mg/N m(3). This study also evaluated the impact of implementing different control systems in an incinerator. Finally, for comparison purposes several samples were analyzed by both high resolution gas chromatography coupled to high resolution mass spectrometry (HRGC-HRMS) and high resolution gas chromatography coupled to ion-trap low resolution mass spectrometry-mass spectrometry (HRGC-IT LRMS/MS). Overall, I-TEQ values deviated about 20-30% between both techniques.

    1995-08-01

    Argonne National Laboratory-East (ANL-E) is developing plans to use vitrification to treat low-level radioactive mixed wastes (LLMW) generated onsite. The ultimate objective of this project is to install a full-scale vitrification system at ANL-E capable of processing the annual generation and historic stockpiles of selected LLMW streams. This project is currently in the process of identifying a range of processible glass compositions that can be produced from actual mixed wastes and additives, such as boric acid or borax. During the formulation of these glasses, there has been an emphasis on maximizing the waste content in the glass (70 to 90 wt %), reducing the overall final waste volume, and producing a stabilized low-level radioactive waste glass. Crucible glass studies with actual mixed waste streams have produced alkali borosilicate glasses that pass the Toxic Characteristic Leaching Procedure (TCLP) test. These same glass compositions, spiked with toxic metals well above the expected levels in actual wastes, also pass the TCLP test. These results provide compelling evidence that the vitrification system and the glass waste form will be robust enough to accommodate expected variations in the LLMW streams from ANL-E. Approximately 40 crucible melts will be studied to establish a compositional envelope for vitrifying ANL-E mixed wastes. Also being determined is the identity of volatilized metals or off-gases that will be generated.

    1996-08-01

    The US Department of Energy`s (DOE) Office of Environmental Management (EM) Office of Science and Technology (OST) has conducted studies of integrated thermal treatment systems and integrated nonthermal treatment systems (INTS) for treating contact handled, alpha and non-alpha mixed low level radioactive waste (MLLW). The MLLW in the DOE complex consists of a wide variety of organic and inorganic solids and liquids contaminated with radioactive substances. Treatment systems are needed to destroy organic material and stabilize residues prior to land disposal. In May 1996 the Deputy Assistant Secretary for OST appointed an Independent Peer Review Panel to: (1) review and comment on the INTS Study; (2) make recommendations on the most promising thermal and nonthermal treatment systems; (3) make recommendations on research and development necessary to prove the performance of nonthermal and thermal technologies; and (4) review and comment on the preliminary draft of the ITTS/INTS Comparison Report. This report presents the primary conclusions and recommendations based on the review of the INTS study and the comparison report. System selection, overviews, comparisons, cost estimations and sensitivity analyses, and recommended R and D engineering needs are then described and discussed.

    Research on acetylcholinesterase inhibitors (ChEIs) indicates that long term exposure increases the level of nicotinic acetylcholine receptors (nAChRs) but the effects of donepezil on nAChRs are not well studied. Therefore, we investigated the effects of sub-chronic donepezil administration on nAChRs in rats and rat pheochromocytoma PC-12 cells. Male Sprague Dawley rats were administered donepezil (0.7 and 2.4 micromoles/kg), nicotine (2.5 micromoles/kg) or saline subcutaneously twice daily for 14 days, PC-12 cells were incubated with 10(-6) to 10(-4) M donepezil for 72 hours and nAChR levels were determined by receptor binding assay using the nAChR ligands [3H]-epibatidine (EPI) for non-alpha 7 nAChRs and [3H]-methyllyconitine (MLA) for alpha 7 nAChRs. Chronic donepezil administration at 1.4 micromoles/kg/day and 4.8 micromoles/ kg/day significantly increased [3H]-epibatidine binding in the cortex to 126 +/- 1.3% and 127 +/- 3.2% of the saline control animals, respectively. [3H]-MLA binding in the cortex increased to 114 +/- 4.4% and 124 +/- 2.8% of the control group for the high and low dose groups, respectively. Hippocampal [3H]-EPI binding in the low dose and high dose groups significantly increased to 135 +/- 3.6% and 125 +/- 4.6% of the controls, respectively while there were no changes in the level of [3H]-MLA binding. In striatal homogenates, neither [3H]-EPI nor [3H]-MLA binding were significantly effected at either dose of donepezil. In PC-12 cells, [3H]-EPI binding was increased at the non-physiological 10(-4)M concentration only. There was no effect of donepezil on [3H]-MLA binding at any concentration examined. These results indicate that donepezil increases cortical alpha 7 and non-alpha 7 nAChRs, hippocampal non-alpha 7 nAChRs but does not influence striatal nAChR levels. Furthermore, the lack of an effect on the alpha 7-nAChRs in PC-12 cells suggests that the increase in cortical alpha 7 nAChRs may be an indirect effect of increased acetylcholine

    We investigated the relationships of serum uric acid levels with the progression of atherosclerosis in patients with peripheral arterial disease (PAD) after treatment. Subjects were male patients diagnosed with PAD. Atherosclerosis at the common carotid artery was evaluated based on its intima-media thickness (IMT). Leg arterial flow was evaluated by measuring ankle-brachial index (ABI) and exercise-induced decrease in ABI. Among various risk factors including age, blood pressure, adiposity, estimated glomerular filtration rate, and blood lipid, blood glucose, uric acid, fibrinogen and C-reactive protein levels, only uric acid levels showed significant correlations with ABI [Pearson's correlation coefficient, -0.292 (p<0.01)] and leg exercise-induced decrease in ABI [Pearson's correlation coefficient, 0.236 (p< 0.05)]. However, there was no significant correlation between uric acid levels and maximum or mean IMT. Odds ratios of subjects with the 3rd tertile versus subjects with the 1st tertile for uric acid levels were significantly higher than the reference level of 1.00 for low ABI [4.44 (95% confidence interval, 1.45-13.65, p<0.01)] and for high % decrease in ABI after exercise [4.31 (95% confidence interval, 1.34-13.82, p<0.05)]. The associations of uric acid levels with the indicators of leg ischemia were also found after adjustment for age, history of revascularization therapy, diabetes, smoking, alcohol consumption, body mass index, triglyceride levels, and renal function. Uric acid levels are associated with the degree of leg ischemia in patients with PAD. Further interventional studies are needed to determine whether the correction of uric acid levels is effective in preventing the progression of PAD.

    The aim of this study was to quantify the proportion of regulatory T cells (Treg ) and cytokine expression by peripheral blood mononuclear cells (PBMCs) in patients with active non-infectious uveitis, and to evaluate the effect of in-vitro treatment with infliximab, dexamethasone and cyclosporin A on Treg levels and cytokine production in PBMCs from uveitis patients and healthy subjects. We included a group of 21 patients with active non-infectious uveitis and 18 age-matched healthy subjects. The proportion of forkhead box protein 3 (FoxP3)(+) Treg cells and intracellular tumour necrosis factor (TNF)-α expression in CD4(+) T cells was determined by flow cytometry. PBMCs were also either rested or activated with anti-CD3/anti-CD28 and cultured in the presence or absence of dexamethasone, cyclosporin A and infliximab. Supernatants of cultured PBMCs were collected and TNF-α, interleukin (IL)-10, IL-17 and interferon (IFN)-γ levels were measured by enzyme-linked immunosorbent assay (ELISA). No significant differences were observed in nTreg levels between uveitis patients and healthy subjects. However, PBMCs from uveitis patients produced significantly higher amounts of TNF-α and lower amounts of IL-10. Dexamethasone treatment in vitro significantly reduced FoxP3(+) Treg levels in PBMCs from both healthy subjects and uveitis patients, and all tested drugs significantly reduced TNF-α production in PBMCs. Dexamethasone and cyclosporin A significantly reduced IL-17 and IFN-γ production in PBMCs and dexamethasone up-regulated IL-10 production in activated PBMCs from healthy subjects. Our results suggest that PBMCs from patients with uveitis express more TNF-α and less IL-10 than healthy subjects, and this is independent of FoxP3(+) Treg levels. Treatment with infliximab, dexamethasone and cyclosporin A in vitro modulates cytokine production, but does not increase the proportion of FoxP3(+) Treg cells.

  19. PERFORMANCE IMPROVEMENT OF CROSS-FLOW FILTRATION FOR HIGH LEVEL WASTE TREATMENT

    2011-01-12

    In the interest of accelerating waste treatment processing, the DOE has funded studies to better understand filtration with the goal of improving filter fluxes in existing cross-flow equipment. The Savannah River National Laboratory (SRNL) was included in those studies, with a focus on start-up techniques, filter cake development, the application of filter aids (cake forming solid precoats), and body feeds (flux enhancing polymers). This paper discusses the progress of those filter studies. Cross-flow filtration is a key process step in many operating and planned waste treatment facilities to separate undissolved solids from supernate slurries. This separation technology generally has the advantage of self-cleaning through the action of wall shear stress created by the flow of waste slurry through the filter tubes. However, the ability of filter wall self-cleaning depends on the slurry being filtered. Many of the alkaline radioactive wastes are extremely challenging to filtration, e.g., those containing compounds of aluminum and iron, which have particles whose size and morphology reduce permeability. Unfortunately, low filter flux can be a bottleneck in waste processing facilities such as the Savannah River Modular Caustic Side Solvent Extraction Unit and the Hanford Waste Treatment Plant. Any improvement to the filtration rate would lead directly to increased throughput of the entire process. To date increased rates are generally realized by either increasing the cross-flow filter axial flowrate, limited by pump capacity, or by increasing filter surface area, limited by space and increasing the required pump load. SRNL set up both dead-end and cross-flow filter tests to better understand filter performance based on filter media structure, flow conditions, filter cleaning, and several different types of filter aids and body feeds. Using non-radioactive simulated wastes, both chemically and physically similar to the actual radioactive wastes, the authors performed

    This study was designed to show the effect of propylthiouracil treatment on sCD40L, high-sensitivity C-reactive protein, and fetuin-A levels on subjects with subclinical hyperthyroidism. After checking sCD40L, high-sensitivity C-reactive protein, and fetuin-A levels of 35 patients with subclinical hyperthyroidism, each was given 50 mg tablets of propylthiouracil three times daily. After 3 months, sCD40L, high-sensitivity C-reactive protein, and fetuin-A levels were then compared to the levels before treatment. Although high-sensitivity C-reactive protein and sCD40L levels were normal in the subclinical hyperthyroidism patients compared to the healthy controls, fetuin-A levels were statistically significantly higher (*p = 0.022). After treatment, fetuin-A levels of subclinical hyperthyroidism patients decreased statistically significantly compared to the levels before treatment (**p = 0.026). sCD40L and high-sensitivity C-reactive protein levels did not have a statistically significant difference compared to the control group and post-propylthiouracil treatment. In subclinical hyperthyroidism patients, high fetuin-A levels before propylthiouracil treatment and decreases in these levels after treatment in cases with subclinical hyperthyroidism indicated the possibility of preventing long-term cardiac complications with propylthiouracil treatment.

    2012-11-01

    Full Text Available Abstract Sclerostin, a product of a SOST gene, is a protein expressed by osteocytes that inhibits osteoblastic bone formation. Several hormones, including PTH and glucocorticosteroids, have been suggested to be possible regulators of sclerostin production. The influence of thyroid hormones on sclerostin synthesis has not been investigated, so far. The aim of the study was to evaluate sclerostin concentrations in patients before and after treatment of thyrotoxicosis. Patients and methods The study involved 15 patients (4 men, mean age 51.8±15.3 years, mean BMI value - 24.7±3.5, with thyrotoxicosis due to Graves’ disease or toxic multinodular goitre. Serum sclerostin was measured by immunoassay at diagnosis of thyrotoxicosis and after 6–10 weeks of treatment with thiamazole. The data were analysed by means of simple descriptive statistics of location and dispersion and Mann–Whitney U test for pairs of results, before and after thiamazole therapy. Association between variables was evaluated with use of Spearman`s correlation coefficient. Results There was a significant decrease in free T3 (FT3 and free T4 (FT4 concentrations (from 8.74±4.79 pg/ml to 3.54±2.40 pg/ml, and from 4.48±2.21 ng/ml to 1.02±1.07 ng/ml, respectively, p3 or FT4 concentrations. Conclusions Restoration of a euthyroid state in patients with thyrotoxicosis results in a significant decrease in serum sclerostin concentrations. The above mentioned phenomenon may reflect lowering of bone metabolism, but a possible direct influence of thyroid hormones on SOST gene needs to be investigated.

    Full Text Available Objective: The treatment of subtrochanteric fractures is challenging and treatment modalities and implants are constantly evolving. This study attempts to revisit and compare extramedullary vs. intramedullary devices in relatively young population. Methods: Thirty patients with subtrochanteric fractures were enrolled and treated with extramedullary or intramedullary devices and follow-up continued one year for clinico-radiological assessment. Results: The mean age of patients was 37.53 years. Most were males between 21-40 years old. The dominant mode of injury was traffic accidents (66%. Fractures were classifi ed according to Russell-Taylor classifi cation. Forty percent were Russell-Taylor type IA, 37% type IB and 23% type IIA. Average time to surgery was 3.6 days from the time of admission to hospital. Mean duration of surgery was 45 minutes for intramedullary device (group A and 105 minutes for extramedullary device (group B. Average blood loss was 100 ml in group A and 200 ml in group B. Mean duration of radiation exposure was 130 seconds and 140 seconds for groups A and B, while average duration of hospital stay was 12 days and 16 days respectively. Excellent results were seen in 47% of cases in group A and 33% of cases in group B. Conclusion: Intramedullary device is a reliable implant for subtrochanteric fractures. It has high rates of union with minimal soft-tissue damage. Intramedullary fixation has biological and biomechanical advantages, but surgery is technically demanding. Gradual learning and patience is needed to make this method truly rewarding. Key words: Subtrochanteric fractures; Intramedullary; Dynamic hip screw

  5. Fragile X and autism: Intertwined at the molecular level leading to targeted treatments.

    Fragile X syndrome (FXS) is caused by an expanded CGG repeat (> 200 repeats) in the 5' untranslated portion of the fragile mental retardation 1 gene (FMR1), leading to deficiency or absence of the FMR1 protein (FMRP). FMRP is an RNA carrier protein that controls the translation of several other genes that regulate synaptic development and plasticity. Autism occurs in approximately 30% of FXS cases, and pervasive developmental disorder, not otherwise specified (PDD-NOS) occurs in an additional 30% of cases. Premutation repeat expansions (55 to 200 CGG repeats) may also give rise to autism spectrum disorders (ASD), including both autism and PDD-NOS, through a different molecular mechanism that involves a direct toxic effect of the expanded CGG repeat FMR1 mRNA. RNA toxicity can also lead to aging effects including tremor, ataxia and cognitive decline, termed fragile X-associated tremor ataxia syndrome (FXTAS), in premutation carriers in late life. In studies of mice bearing premutation expansions, there is evidence of early postnatal neuronal cell toxicity, presenting as reduced cell longevity, decreased dendritic arborization and altered synaptic morphology. There is also evidence of mitochondrial dysfunction in premutation carriers. Many of the problems with cellular dysregulation in both premutation and full mutation neurons also parallel the cellular abnormalities that have been documented in autism without fragile X mutations. Research regarding dysregulation of neurotransmitter systems in FXS, including the metabotropic glutamate receptor (mGluR)1/5 pathway and γ aminobutyric acid (GABA)A pathways, have led to new targeted treatments for FXS. Preliminary evidence suggests that these new targeted treatments will also be beneficial in non-fragile X forms of autism.

    2004-07-01

    An association between chronic fatigue syndrome (CFS) and abnormalities of the hypothalamo-pituitary-adrenal axis has been described, and other adrenal steroid abnormalities have been suggested. Dehydroepiandrostenedione (DHEA) and its sulphate (DHEA-S), apart from being a precursor of sex steroids, have other functions associated with memory, depression and sleep. It has been suggested that CFS may be associated with a state of relative DHEA(-S) deficiency. Therefore we investigated basal levels of DHEA(-S), the cortisol/DHEA molar ratio and the responsiveness of DHEA to stimulation by corticotrophin-releasing hormone (CRH). Recent studies have also suggested that low dose hydrocortisone may be effective at reducing fatigue in CFS. We therefore also assessed these parameters prior to and following treatment with low dose oral hydrocortisone. Basal levels of serum DHEA, DHEAS and cortisol were measured in 16 patients with CFS without depression and in 16 controls matched for age, gender, weight, body mass index and menstrual history. CRH tests (1 g/kg i.v.) were carried out on all subjects and DHEA measured at 0, +30 and +90 min. In the patient group, CRH tests were repeated on two further occasions following treatment with hydrocortisone (5 or 10 mg, p.o.) or placebo for 1 month each in a double-blind cross over study protocol. Basal levels of DHEA were higher in the patient, compared to the control, group (14.1+/-2.2 vs. 9.0+/-0.90 ng/ml, P=0.04), while levels of DHEAS in patients (288.7+/-35.4 microg/dl) were not different from controls (293.7+/-53.8, P=NS). Higher DHEA levels were correlated with higher disability scores. Basal cortisol levels were higher in patients, and consequently the cortisol/DHEA molar ratio did not differ between patients and controls. Levels of DHEA (8.9+/-0.97 ng/ml, P=0.015) and DHEAS (233.4+/-41.6 microg/dl, P=0.03) were lower in patients following treatment with hydrocortisone. There was a rise in DHEA responsiveness to CRH in the

    Chronic Lisfranc injury is a subtle and severe injury in high-level athletes, including dancers. This patient population is generally intolerant of intra-articular screw fixation and can develop significant post-traumatic arthritis with potentially career ending complications. Flexible fixation with suture-button devices provides potential restoration of physiologic motion at the joint, with appropriate support for healing that may facilitate return to en pointe activities for dancers. We hypothesized that the suture-button device would restore motion at the Lisfranc joint and allow for return to activities in this particular population without the limitations and complications of rigid fixation. We operated on seven dancers and high-level athletes with diagnosed Lisfranc injuries by installing a suture-button device. All patients had failed conservative management after late presentation. They were allowed to return to sport in 6 months, preoperative and postoperative American Orthopaedic Foot and Ankle Score (AOFAS) foot scores were obtained, and patients were followed for a minimum of 15 months. All seven returned to full activities in 6 months, with radiographic evidence of fixation and no complications to date. AOFAS foot scores improved from an average of 65 preoperatively to an average of 97 postoperatively at latest follow-up. It is concluded that flexible fixation with suture-button type device represents a viable alternative to screw fixation or fusion that may allow dancers and athletes to return to previous levels of activity after Lisfranc injury. This case series represents to our knowledge the first application of this device to a unique population that requires flexibility at the Lisfranc joint for performance.

    To document the clinical results of arthroscopic iliopsoas tenotomies performed at the level of the labrum to treat labral injuries caused by iliopsoas impingement. From a review of the database of the senior author (J.S.K.) of 300 hip arthroscopies that were performed between September 2009 and May 2011, 30 patients who had an arthroscopic release of the iliopsoas tendon at the level of the labrum and at least 2 years' follow-up were identified. In all cases the release was performed to treat a tight psoas tendon that was found at arthroscopy to be impinging on a torn or inflamed labrum. The results of hip arthroscopy in these patients were assessed with Byrd's 100-point modified Harris Hip Score system before arthroscopy and at 3, 6, 12, and 24 months after surgery. The mean age of the 30 patients was 35 years, and their preoperative scores averaged 43 points. After surgery, the patients had 6-month scores that averaged 73 points and 12-month scores that averaged 84 points (range, 40 to 100 points). Over the first postoperative year, in 3 of the 5 patients whose preoperative ultrasound imaging showed snapping of the tendon, recurrent painful snapping developed in the hip. All 3 had iliopsoas bursa injections and had immediate relief of their hip pain. In 2 patients the relief was temporary and an arthroscopic release of the tendon at the lesser trochanter was performed. The 2-year scores of the remaining 28 patients who did not have a second iliopsoas tenotomy averaged 88 points, and 23 of these patients had good or excellent results (scores ≥80 points). An arthroscopic release of the iliopsoas tendon at the level of the labrum was effective for alleviating hip pain from labral lesions caused by impingement of the tendon in 23 of 30 patients (77%). The remaining 7 patients had persistent hip pain and hip scores lower than 80 points because of recurrent snapping of the tendon (3), development of avascular necrosis (1), progression of degenerative joint disease

  10. Extending an evidence hierarchy to include topics other than treatment: revising the Australian 'levels of evidence'.

    In 1999 a four-level hierarchy of evidence was promoted by the National Health and Medical Research Council in Australia. The primary purpose of this hierarchy was to assist with clinical practice guideline development, although it was co-opted for use in systematic literature reviews and health technology assessments. In this hierarchy interventional study designs were ranked according to the likelihood that bias had been eliminated and thus it was not ideal to assess studies that addressed other types of clinical questions. This paper reports on the revision and extension of this evidence hierarchy to enable broader use within existing evidence assessment systems. A working party identified and assessed empirical evidence, and used a commissioned review of existing evidence assessment schema, to support decision-making regarding revision of the hierarchy. The aim was to retain the existing evidence levels I-IV but increase their relevance for assessing the quality of individual diagnostic accuracy, prognostic, aetiologic and screening studies. Comprehensive public consultation was undertaken and the revised hierarchy was piloted by individual health technology assessment agencies and clinical practice guideline developers. After two and a half years, the hierarchy was again revised and commenced a further 18 month pilot period. A suitable framework was identified upon which to model the revision. Consistency was maintained in the hierarchy of "levels of evidence" across all types of clinical questions; empirical evidence was used to support the relationship between study design and ranking in the hierarchy wherever possible; and systematic reviews of lower level studies were themselves ascribed a ranking. The impact of ethics on the hierarchy of study designs was acknowledged in the framework, along with a consideration of how harms should be assessed. The revised evidence hierarchy is now widely used and provides a common standard against which to initially

We aimed to examine myo-ins effects on anti-Mullerian hormone (AMH levels and compare them with those ones obtained administering COC. In this prospective study, 137 PCOS patients, diagnosed according to Rotterdam criteria and admitted to the Reproductive Endocrinology and Infertility Outpatient Clinic at Dokuz Eylul University (Izmir, Turkey, were included. After randomization to COC (n=60 and myo-ins (n=77 arms, anthropometric measurements, blood pressure, Modified Ferriman Gallwey scores were calculated. Biochemical and hormonal analysis were performed, and LH/FSH and Apo B/A1 ratios were calculated. Data analysis was carried out in demographically and clinically matched 106 patients (COC = 54; myo-ins = 52. After 3-month treatment, increase in HDL and decreases in LH and LH/FSH ratio were statistically more significant only in COC group when compared with baseline (in both cases p>0.05. In myo-ins group, fasting glucose, LDL, DHEAS, total cholesterol, and prolactin levels decreased significantly (for all p<0.05.

    Recently, myoinositol (myo-ins) and folic acid combination has gained an important role for treating Polycystic Ovary Syndrome (PCOS), in addition to combined oral contraceptives (COC). We aimed to examine myo-ins effects on anti-Mullerian hormone (AMH) levels and compare them with those ones obtained administering COC. In this prospective study, 137 PCOS patients, diagnosed according to Rotterdam criteria and admitted to the Reproductive Endocrinology and Infertility Outpatient Clinic at Dokuz Eylul University (Izmir, Turkey), were included. After randomization to COC (n = 60) and myo-ins (n = 77) arms, anthropometric measurements, blood pressure, Modified Ferriman Gallwey scores were calculated. Biochemical and hormonal analysis were performed, and LH/FSH and Apo B/A1 ratios were calculated. Data analysis was carried out in demographically and clinically matched 106 patients (COC = 54; myo-ins = 52). After 3-month treatment, increase in HDL and decreases in LH and LH/FSH ratio were statistically more significant only in COC group when compared with baseline (in both cases p > 0.05). In myo-ins group, fasting glucose, LDL, DHEAS, total cholesterol, and prolactin levels decreased significantly (for all p < 0.05). Progesterone and AMH levels, ovarian volume, ovarian antral follicle, and total antral follicle counts lessened significantly in both groups (for all p < 0.05). In PCOS treatment, MYO is observed more effective in reductions of total ovarian volume and AMH levels. PMID:27882049

    The aim was to assess the effect of long-term lamivudine treatment on liver fibrosis by direct assessment of histological scores and by indirect assessment of serum biomarkers in children with chronic hepatitis B (chB). The observation was carried out on 31 children with biopsy proven chB who were nonresponders to previous IFNalpha therapy. The serum concentration of hyaluronan and laminin were measured before and up to 24 months of therapy. ROC analysis was used to calculate the power of the assays to detect advanced liver fibrosis (score > 2 according to Batts & Ludwig). Serum hyaluronan and laminin level were significantly higher in children with chB compared to controls. There was a significant correlation between serum hyaluronan level and the stage of liver fibrosis. The ability of serum hyaluronan to differentiate children with advanced fibrosis from those with mild fibrosis was significant (AUC = 0.7767). Laminin did not allow a useful prediction. Two-year lamivudine treatment did not improve histological fibrosis but it caused significant decrease of serum hyaluronan level. Hyaluronan is a better fibrosis marker than laminin to diagnose children with advanced liver fibrosis. The significant decrease of hyaluronan level during therapy suggests antifibrotic effect of lamivudine in children with chB.

    Several technologies for destroying or decontaminating hazardous wastes were evaluated (during early 1988) as potential processes for treating low-level mixed wastes destined for destruction in the Fluidized Bed Incinerator. The processes that showed promise were retained for further consideration and placed into one (or more) of three categories based on projected availability: short, intermediate, and long-term. Three potential short-term options were identified for managing low-level mixed wastes generated or stored at the Rocky Flats Plant (operated by Rockwell International in 1988). These options are: (1) Continue storing at Rocky Flats, (2) Ship to Nevada Test Site for landfill disposal, or (3) Ship to the Idaho National Engineering Laboratory for incineration in the Waste Experimental Reduction Facility. The third option is preferable because the wastes will be destroyed. Idaho National Engineering Laboratory has received interim status for processing solid and liquid low-level mixed wastes. However, low-level mixed wastes will continue to be stored at Rocky Flats until the Department of Energy approval is received to ship to the Nevada Test Site or Idaho National Engineering Laboratory. Potential intermediate and long-term processes were identified; however, these processes should be combined into complete waste treatment systems'' that may serve as alternatives to the Fluidized Bed Incinerator. Waste treatment systems will be the subject of later work. 59 refs., 2 figs.

    To assess self-reported stress during the performance of different procedures in pediatric dentistry, according to the professional experience of the dentists. During the years 2010 to 2011, an anonymous survey was administered by means of an internet link, and by distribution at professional meetings of dentists . No statistically significant differences in stress were reported for maxilla and mandibular procedures. Placement of a rubber dam was rated as the most stressful procedure among dental students. For general practitioners and specialists, injection of local anesthesia to an anxious child was the most stressful procedure, regardless of age, sex, or years of professional experience. A negative correlation was found between years of experience and level of stress for all the procedures surveyed, but not for the use of nitrous oxide. No differences were found between male and female dentists in stress scores for any of the procedures. Higher rates of stress during operative procedures were reported among dental students than among experienced dentists. Anxiety of the pediatric patients, but not the location of the procedure: maxillary or mandibular, affected the dentists' reported level of stress.

    In this study, a through mold via (TMV) interconnect was developed for an embedded wafer level package (EMWLP) to enable 3D packing applications. The effects of the shape and surface roughness of the epoxy molding wafer on the quality of electroless Cu metallization were investigated for the vertical interconnection. The mold compound is a composite material composed of epoxy resin and filler particles. Therefore, the effect of the amount of filler particles was studied to optimize the shape of the epoxy molding by applying two types of laser drilling modes. In addition, the electroless Cu plating process was optimized to deposit a Cu seed layer along the TMV sidewall. To optimize the TMV process, a desmear process was applied to improve the shape of the TMV sidewall and adhesion between the epoxy molding compound and the dielectric polymer for multilayer metallization.

    Resistance to tetracycline, macrolides and streptomycin was measured for a period of 8 months in soil bacteria obtained from farmland treated with pig manure slurry. This was done by spread plating bacteria on selective media (Luria Bertani (LB) medium supplemented with antibiotics). To account...... for seasonal variations in numbers of soil bacteria, ratios of resistant bacteria divided by total count on nonselective plates were calculated. Soil samples were collected from four different farms and from a control soil on a fifth farm. The control soil was not amended with animal manure. The occurrence...... of tetracycline-resistant bacteria was elevated after spread of pig manure slurry but declined throughout the sampling period to a level corresponding to the control soil. Higher load of pig manure slurry yielded higher occurrence of tetracycline resistance after spreading; however, the tetracycline resistance...

    The nutritional benefits of soybean remain underutilized as the off-flavor present in it limits the consumption and acceptability among people. The aim of the present study was to unveil the effect of the phytohormones methyl jasmonate (MJ: 0, 50 μM, 1 mM, and 15 mM) and salicylic acid (SA: 0, 50 μM, 0.1 mM, and 10 mM) as elicitors on two contrasting off-flavor soybean varieties at different growth stages (1, bloom; 2, pod development; 3, seed development). The effects of two elicitors varied widely and were found to be dose dependent and growth stage independent. SA reduces the lipoxygenase (LOX) and hydroperoxide lyase (HPL) activity, which in turn resulted in reduction in the TBA number and carbonyl value in contrast to MJ. SA 0.1 mM is the most effective dose in reduction of off-flavor determining parameters and protein oxidation, and it reduces the LOX and HPL activity by 2.3- and 2.4-fold, respectively in "high off-flavor" cultivar 'Bragg' compared to "low off-flavor" cultivar 'DS 2706' which showed 1.4- and 2.1-fold, respectively. This reduction in protein oxidation is also supported by enhanced content of antioxidant enzymes. Thus, phytohormone SA can be used in reduction of off-flavor generation, more effectively than MJ treatments, in soybean.

    Concentrations of polychlorinated biphenyls (PCBs) have been measured in sewage sludge samples from 8 urban wastewater treatment plants in Beijing, China. The PCB congeners were analyzed by isotope dilution high resolution gas chromatography/high resolution mass spectrometry method. The concentration of PCBs ranged from 65.6 to 157 ng/g dry weight (dw), with a mean value of 101 ng/g dw. The dioxin-like PCB WHO-TEQs (World Health Organization-Toxic Equivalents) of the sludge were lower than 1 pg /g dw. Consequently, all the concentrations of PCBs in sludge samples were below the upper limit for land application according to the Chinese legislation law for agriculture use. The PCB homologue profiles in sludge samples were dominated by tri-CBs and tetra-CBs. Similar distributions have been found in one of the Chinese PCB commercial products. The patterns of dioxin-like and indicator congeners observed in this study were quite similar in all samples. The predominant congener for dioxin-like and indicator PCBs were PCB-118 and PCB-28, respectively, while PCB-126 had the highest TEQ value.

    The Integral Fast Reactor (IFR) is being developed as a future commercial power source that promises to have important advantages over present reactors, including improved resource conservation and waste management. The spent metal alloy fuels from an IFR will be processed in an electrochemical cell operating at 500{degree}C with a molten chloride salt electrolyte and cadmium metal anode. After the actinides have been recovered from several batches of core and blanket fuels, the salt cadmium in this electrorefiner will be treated to separate fission products from residual transuranic elements. This treatment produces a waste salt that contains the alkali metal, alkaline earth, and halide fission products; some of the rare earths; and less than 100 nCi/g of alpha activity. The treated metal wastes contain the rest of the fission products (except T, Kr, and Xe) small amounts of uranium, and only trace amounts of transuranic elements. The current concept for the salt waste form is an aluminosilicate matrix, and the concept for the metal waste form is a corrosion-resistant metal alloy. The processes and equipment being developed to treat and immobilize the salt and metal wastes are described.

Pre-treatment LDH levels were evaluated to identify a potential correlation with progression-free survival (PFS, overall survival (OS and objective response rate.Information on pre-treatment LDH levels was available for 344 patients. High LDH levels were predictive of a lower median PFS (8.1 months vs. 9.2 months, p< 0.0001 and median OS (16.1 months vs. 25.2 months, p< 0.0001 in the overall population. In the chemotherapy plus bevacizumab group, median PFS was 9.1 and 9.8 months in patients with high LDH and low LDH, respectively (p= 0.073, whereas in the chemotherapy-only arm it was 6.9 and 9.1 months, respectively (p < 0.0001. In patients with high LDH, the addition of bevacizumab to chemotherapy led to a reduction in the rate of progressive disease (16.4 vs. 30.5%, p= 0.081 and to a prolonged PFS (p= 0.028.A high LDH value was confirmed as a marker of poor prognosis. Bevacizumab reduced the progressive disease rate and improved PFS in the high-LDH subgroup, making serum LDH a potentially effective an easily available and marker to select patients who benefit from bevacizumab.NCT01878422 ClinicalTrials.gov.

    Obesity can cause or worsen asthma. Compared with common asthma, obese asthma is difficult to control. Statins are effective serum cholesterol-lowering agents in clinical practice, and they also have anti-inflammatory properties, which in theory are potentially beneficial in asthma. Many studies have shown that simvastatin has good therapeutic effect in animal models of asthma. However, the therapeutic effect and action mechanism of simvastatin for obese asthma remain unclear. Leptin, a satiety hormone, is in positive correlation with total body fat mass and may also play a significant role in the pathogenesis of asthma. In this study, we use the method of high-fat diet and ovalbumin (OVA) sensitization and challenge to establish the mouse model of obesity and asthma, and find that obese asthmatic mice has higher levels of glucose, lipid and leptin in serum, and neutrophil percentage in bronchoalveolar lavage fluid (BALF), and more severe airway inflammation and structural changes in lung tissues than non-obese asthmatic mice, and respond poorly to dexamethasone treatment, which indicates that obese asthma might belong to steroid-resistant (SR) asthma. Simvastatin treatment reduces the levels of glucose, lipid, leptin and neutrophil percentage, and improves airway inflammation and remodeling, which can be as a potential therapeutic target used in the treatment of obese asthma in humans. Correlation analysis shows that there is positive correlation between neutrophil percentage and serum leptin/cholesterol level, which indicates that the therapeutic efficacy of simvastatin on obese asthma might be associated with improving dyslipidemia and decreasing leptin level.

    Background Evidence suggests that systemic inflammation may play an important role in the progression and morbidity of chronic obstructive pulmonary disease. It remains controversial whether inhaled corticosteroid in combination with a long-acting β2-adrenoceptor agonist can attenuate systemic inflammation. We evaluated the effect of salmeterol/fluticasone propionate on circulating C-reactive protein level in stable chronic obstructive pulmonary disease patients.Methods An open-label clinical trial was conducted to recruit 122 outpatients with stable moderate-to-severe chronic obstructive pulmonary disease from department of respiratory medicine in two teaching hospitals between June 2007 and March 2008. Patients were randomized into two groups (1:1) to receive either the combination of 50 ug salmeterol and 500 ug fluticasone twice daily (n=61), or the combination of 206 ug albuterol and 36 ug ipratropium q.i.d (n=61) over 6 months. Circulating C-reactive protein concentrations were measured before randomization and during the follow-up. The efficacy of treatment was also assessed by spirometry, as well as health status and dyspnea score at baseline and after 6-month treatment.Results Baseline characteristics of two groups were similar. Compared with ipratropium/albuterol, the combination of salmeterol/fluticasone significantly reduced circulating level of C-reactive protein (-1.73 vs. 0.08 mg/L, respectively, P <0.05) after 6-month treatment. Forced expiratory volume in one second (FEV1) and health status also improved significantly in salmeterol/fluticasone group compared with ipratropium/albuterol. Salmeterol/fluticasone treatment subjects who had a decrease of circulating C-reactive protein level had a significant improvement in FEV1 and St George's Respiratory Questionnaire total scores compared with those who did not (185 vs. 83 ml and -5.71 vs. -1.79 units, respectively, both P<0.01).Conclusion Salmeterol/fluticasone treatment reduced circulating C

    The Department of Energy (DOE) has prepared an environmental assessment (EA) (DOE/EA-1292) to evaluate the proposed treatment of low level mixed waste (LLMW) at the Rocky Flats Environmental Technology Site (Site). The purpose of the action is to treat LLMW in order to meet the Land Disposal Restrictions specified by the Resource Conservation and Recovery Act and the waste acceptance criteria of the planned disposal site(s). Approximately 17,000 cubic meters (m{sup 3}) of LLMW are currently stored at the Site. Another 65,000 m{sup 3}of LLMW are likely to be generated by Site closure activities (a total of 82,000 m{sup 3} of LLMW). About 35,000 m{sup 3} can be directly disposed of off-site without treatment, and most of the remaining 47,000 m{sup 3} of LLMW can be treated at off-site treatment, storage, and disposal facilities. However, some LLMW will require treatment on-site, either because it does not meet shipping requirements or because off-site treatment is not available for these particular types of LLMW. Currently, this LLMW is stored at the Site pending the development and implementation of effective treatment processes. The Site needs to treat this LLMW on-site prior to shipment to off-site disposal facilities, in order to meet the DOE long-term objective of clean up and closure of the Site. All on-site treatment of LLMW would comply with applicable Federal and State laws designed to protect public health and safety and to enhance protection of the environment. The EA describes and analyzes the environmental effects of the proposed action (using ten mobile treatment processes to treat waste on-site), and the alternatives of treating waste onsite (using two fixed treatment processes), and of taking no action. The EA was the subject of a public comment period from February 3 to 24, 1999. No written or other comments regarding the EA were received.

Median blood loss was 6000 (600–27 000 ml. Complications rate was 62.8 %, 90-day mortality – 13.2 %. Intraoperative complications were registered in 80 (47.9 %, postoperative – in 66 (40.5 % (grade II – 16 (9.8 %, grade IIIb – 1 (0.6 %, grade IVа – 28 (17.2 %, grade IVb – 3 (1.8 %, grade V – 18 (11.1 % patients. Modified thrombectomy technique insignificantly decreased blood loss compared to thrombectomy with CPB, did nоt increase complications rate including pulmonary vein thromboembolism, or mortality. Five-year overall, cancer-specific and recurrence-free survival was 46.2, 58.3 and 47.1 %, respectively. Thrombectomy technique did nоt affect survival.Conclusion. In selected patients with mobile thrombi transdiaphragmatic approach allows to avoid the use of CPBP and decrease surgical morbidity without survival compromising.

    A number of waste components in US defense high level radioactive wastes (HLW) have proven challenging for current Joule heated ceramic melter (JHCM) operations and have limited the ability to increase waste loadings beyond already realized levels. Many of these “troublesome" waste species cause crystallization in the glass melt that can negatively impact product quality or have a deleterious effect on melter processing. Recent efforts at US Department of Energy laboratories have focused on understanding crystallization behavior within HLW glass melts and investigating approaches to mitigate the impacts of crystallization so that increases in waste loading can be realized. Advanced glass formulations have been developed to highlight the unique benefits of next-generation melter technologies such as the Cold Crucible Induction Melter (CCIM). Crystal-tolerant HLW glasses have been investigated to allow sparingly soluble components such as chromium to crystallize in the melter but pass out of the melter before accumulating.The Hanford site AZ-101 tank waste composition represents a waste group that is waste loading limited primarily due to high concentrations of Fe2O3 (also with high Al2O3 concentrations). Systematic glass formulation development utilizing slightly higher process temperatures and higher tolerance to spinel crystals demonstrated that an increase in waste loading of more than 20% could be achieved for this waste composition, and by extension higher loadings for wastes in the same group. An extended duration CCIM melter test was conducted on an AZ-101 waste simulant using the CCIM platform at the Idaho National Laboratory (INL). The melter was continually operated for approximately 80 hours demonstrating that the AZ-101 high waste loading glass composition could be readily processed using the CCIM technology. The resulting glass was close to the targeted composition and exhibited excellent durability in both

    Axitinib is used after failure of first line treatment for metastatic renal cell carcinoma (mRCC). A known side effect is the increase of haemoglobin level (HbL) during treatment with a suspected correlation with better outcome. Our objective was to examine whether HbL increase during the first three months of axitinib treatment is associated with better prognosis. Retrospective multicentre analysis including patients with mRCC treated with axitinib for at least three months from 2012 to 2014. Progression-free survival (PFS) was analysed by a Cox model according to gender, International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) prognostic score, high blood pressure (hBP), and maximum increase in HbL within the first three months of treatment. Ninety-eight patients were analysed (71% men; median age at treatment initiation: 62 years; IMDC: 24%, 50%, and 26% in the favourable, intermediate, and poor-risk group, respectively). Patients received axitinib for a median of 8 months. During the first three months, the median increase of HbL was +2.3 g/dL (-1.1; 7.2). Fifty-six (57%) patients developed hBP. In multivariate analysis, after adjustment for performance status (P increase ≥2.3 g/dL and any grade hBP was significantly associated with longer PFS (HR = 0.40, 95%CI [0.24; 0.68]). Early HbL increase during axitinib treatment combined with hBP is an independent predictive factor of PFS. These results require validation in a prospective setting.

    Full Text Available Objective: Low-level laser therapy (LLLT has been increasingly in use over the last few decades in both medicine and dentistry. It has been suggested that LLLT may be helpful in pulpal wound healing following pulp exposure. The purpose of this study was to comparethe effectiveness of LLLT and formocresol (FC application in healing of remaining pulp following pulp amputation in primary molars.Materials and Methods: A total of 23 contralateral pairs of teeth from 11 children aged 4 to 7 years were selected and matched using clinical and radiographic criteria. One toothfrom each pair was randomly assigned to the LLLT pulpotomy and the to FC pulpotomy group. During a 6-month follow-up period, the teeth were examined clinically and radiographically.Eight patients (four in each group completed six-month and 6 patients (threein each group completed one-year follow-up.Results: Clinically, no complication was observed in the teeth. However, radiographic assessment revealed signs of periradicular radiolucency in two teeth in LLLT group.Conclusion: Findings of this investigation show that LLLT can be used successfully as a complementary step to pulpotomy procedure in order to help the healing of amputated pulp. Longer follow-up periods are recommended to investigate long-term effect of LLLTpulpotomy on pulp.

DLTS revealed the presence of three prominent electron traps in the material in the temperature range 20-300 K. However, L-DLTS with its higher resolution enabled the splitting of two narrowly spaced emission rates. Consequently four electron traps at, E{sub C}-0.33 eV, E{sub C}-0.36 eV, E{sub C}-0.38 eV and E{sub C}-0.56 eV were observed in the control sample. Following hydrogenation, all these traps were passivated with a new complex (presumably the M3), emerging at E{sub C}-0.58 eV. Isochronal annealing of the passivated material between 50 and 300 {sup o}C, revealed the emergence of a secondary defect, not previously observed, at E{sub C}-0.37 eV. Finally, the effect of hydrogen passivation is completely reversed upon annealing at 300 {sup o}C, as all the defects originally observed in the reference sample were recovered.

    The objective of this study is to investigate the impact of control of blood glucose level during treatment of sudden deafness. A retrospective study was performed involving 197 patients from January, 2011 to September, 2015. All patients were administrated prednisolone (Pharmaprednisolone tab(®), 5 mg/T; KoreaPharma) p.o under the following regimen: 60 mg/day for 4 days, 40 mg/day for 2 days, 30 mg/day for 1 day, 20 mg/day for 1 day, and 10 mg/day for 2 days. During treatment, pure tone audiometry and blood glucose level were investigated for each patient and the results were statistically analyzed. Mean hearing improvement was 19.2 dB for the non-diabetes group and 24.8 dB for the diabetes group. The greater improvement for diabetics was not statistically significant (p = 0.146). Hearing improvement was 25.1 dB for subjects with mean blood glucose 200 mg/dl; the difference was not statistically significant (p = 0.267). Mean blood glucose level was 200.8 mg/dl for subjects with hearing improvement >20 dB and 181.8 mg/dl for subjects with hearing improvement sudden deafness does not have a direct effect on prognosis.

    Serum fucose, sialic acid, haptoglobine and phospholipids were determined in 167 women with breast cancer stages I--III, 30 with benign lesions of the breast, 42 women in various physiological states of the mammary gland (pregnancy, early childbed and lactation) and compared with 30 healthy women as control. Serial determinations of these parameters during the radio-surgical treatment were done in 28 patients with breast cancer stage III. Fucose and phospholipids levels were significantly increased respectively decreased in the group of patients with breast cancers but unmodified in the others. Sialic acid and haptoglobine -- increased in patients with cancer -- were also elevated in patients with early childbed and benign affections of the breast. The surveillance of these four parameters during the radio-surgical treatment of breast cancer evidenced a good correlation between their modified levels and clinical state of the patients. The increase in fucose, sialic acid and haptoglobine respectively the decrease in phospholipids levels was associated with the clinical evidence of recurrences and metastases.

    The primary cause of hearing loss includes damage to cochlear hair cells. Low-level laser therapy (LLLT) has become a popular treatment for damaged nervous systems. Based on the idea that cochlea hair cells and neural cells are from same developmental origin, the effect of LLLT on hearing loss in animal models is evaluated. Hearing loss animal models were established, and the animals were irradiated by 830-nm diode laser once a day for 10 days. Power density of the laser treatment was 900 mW/cm2, and the fluence was 162 to 194 J. The tympanic membrane was evaluated after LLLT. Thresholds of auditory brainstem responses were evaluated before treatment, after gentamicin, and after 10 days of LLLT. Quantitative scanning electron microscopic (SEM) observations were done by counting remaining hair cells. Tympanic membranes were intact at the end of the experiment. No adverse tissue reaction was found. On SEM images, LLLT significantly increased the number of hair cells in middle and basal turns. Hearing was significantly improved by laser irradiation. After LLLT treatment, both the hearing threshold and hair-cell count significantly improved.

    Injury to axons close to the neuronal bodies in the mammalian central nervous system causes a large proportion of parenting neurons to degenerate. It is known that optic nerve transection close to the eye in rodents leads to a loss of about half of retinal ganglion cells in 1 week and about 90% in 2 weeks. Using low level laser treatment in the present study, we demonstrated that treatment with helium-neon (660 nm) laser with 15 mW power could delay retinal ganglion cell death after optic nerve axotomy in adult hamsters. The effect was most apparent in the ifrst week with a short period of treatment time (5 minutes) in which 65–66% of retinal ganglion cells survived the optic nerve axotomy whereas 45–47% of retinal ganglion cells did so in optic nerve axotomy controls. We also found that single dose and early commencement of laser irradiation were important in protecting retinal ganglion cells following optic nerve axotomy. These ifndings thus convincingly show that appropriate laser treatment may be neuroprotective to retinal gan-glion cells.

    Adiponectin is a cardioprotective adipocytokine. Serum adiponectin concentration decreases in patients who are obese but increases in patients with chronic heart failure (CHF). The aim of this study was to explore the temporal changes in serum adiponectin concentration following treatment for acute decompensated heart failure (ADHF). Serum adiponectin was measured on admission and at discharge in 95 patients who were admitted to our hospital with ADHF. Ten patients without heart failure (HF) served as controls. Serum adiponectin concentration was higher on admission in HF patients than in the controls (22.6±13.3 μg/mL vs 9.3±3.9 μg/mL, P<.01). Serum adiponectin concentration decreased after treatment in HF patients (18.0±11.7 μg/mL vs 22.6±13.3 μg/mL, P<.01). The larger temporal decrease in adiponectin level in ADHF was associated with the lower incidence of cardiac death or HF hospitalizations (log-rank, P<.05). Serum adiponectin concentration was elevated in ADHF and decreased following the treatment. How much serum adiponectin decreases in response to treatment in ADHF is an important determinant of the prognosis. © 2010 Wiley Periodicals, Inc.

    Visfatin is a recently discovered adipocytokine that contributes to glucose and obesity-related conditions. Until now, its responses to the insulin-sensitizing agent metformin and to exercise are largely unknown. We aim to investigate the impact of metformin treatment and/or swimming exercise on serum visfatin and visfatin levels in subcutaneous adipose tissue (SAT), peri-renal adipose tissue (PAT) and skeletal muscle (SM) of high-fat-induced obesity rats. Sprague-Dawley rats were fed a normal diet or a high-fat diet for 16 weeks to develop obesity model. The high-fat-induced obesity model rats were then randomized to metformin (MET), swimming exercise (SWI), or adjunctive therapy of metformin and swimming exercise (MAS), besides high-fat obesity control group and a normal control group, all with 10 rats per group. Zoometric and glycemic parameters, lipid profile, and serum visfatin levels were assessed at baseline and after 6 weeks of therapy. Visfatin levels in SAT, PAT and SM were determined by Western Blot. Metformin and swimming exercise improved lipid profile, and increased insulin sensitivity and body weight reduction were observed. Both metformin and swimming exercise down-regulated visfatin levels in SAT and PAT, while the adjunctive therapy conferred greater benefits, but no changes of visfatin levels were observed in SM. Our results indicate that visfatin down-regulation in SAT and PAT may be one of the mechanisms by which metformin and swimming exercise inhibit obesity.

    Full Text Available INTRODUCTION: Different low-level laser (LLL irradiation protocols have been tested to accelerate orthodontic tooth movement (OTM. Nevertheless, divergent results have been obtained. It was suggested that the stimulatory action of low level laser irradiation occurs during the proliferation and differentiation stages of bone cellular precursors, but not during later stages. OBJECTIVE: The purpose of this study was to determine the effect of two protocols of LLL irradiation on experimental tooth movement: One with daily irradiations and another with irradiations during the early stages. METHODS: Thirty-six rats were divided into control groups (CG1, CG2, CG3 and irradiated groups (IrG1, IrG2, IrG3 according to the presence of: experimental tooth movement, laser irradiation, type of laser irradiation protocol and date of euthanasia (3th or 8th day of experiment. At the end of experimental periods, a quantitative evaluation of the amount of OTM was made and the reactions of the periodontium were analyzed by describing cellular and tissue reactions and by counting blood vessels. RESULTS: The amount of OTM revealed no significant differences between groups in the same experimental period (p INTRODUÇÃO: diferentes protocolos de irradiação por laser de baixa potência (LBP têm sido testados para potencializar o movimento ortodôntico; entretanto, há resultados divergentes.

    Minimal hepatic encephalopathy (MHE) has been shown to affect daily functioning, quality of life, driving and overall mortality. However, little is known about treating or diagnosing early impairments involved in MHE. We studied one of its precipitating factors, portal hypertension. The purpose was to evaluate an enhancement in neuronal metabolism through low-light-level therapy (LLLT) and whether this therapy has effects on behavioural task acquisition. Rats were trained to perform a stimulus-response task using the Morris water maze. Three groups of animals were used: a SHAM (sham-operated) group (n = 7), a portal hypertension (PH) group (n = 7) and a PH + LLLT group (n = 7). The triple portal vein ligation method was used to create an animal model of the early developmental phase of HE, and then the animals were exposed to 670 + 10 nm LED light at a dose of 9 J/cm(2) once a day for 7 days. The metabolic activity of the brains was studied with cytochrome c oxidase histochemistry. There were differences in behavioural performance, with an improvement in the PH + LLLT group. Energetic brain metabolism revealed significant differences between the groups in all the brain structures analysed, except the anterodorsal thalamus. At the same time, in different brain networks, the PH group showed a more complicated relationship among the structures, while the SHAM and PH + LLLT groups had similar patterns. In this study, we provide the first preliminary insights into the validity of LLLT as a possible intervention to improve memory under minimal hepatic encephalopathy conditions.

    Recent research evidence shows that the receptor activator of nuclear factor-kappa B ligand (RANKL) and osteoprotegerin (OPG) play an important role in osteoclastogenesis and the inflammatory bone loss during periodontitis. Bone remodeling process is dependent on the balance of these two proteins while a high ratio of RANKL/OPG characterizes the increased osteolytic process and it has been reported in inflammatory diseases including the periodontal disease. The purpose of this study was to determine the OPG and RANKL mRNA levels in periodontal tissues derived from patients with advanced chronic periodontitis after non-surgical periodontal therapy (SRP) and to compare the RANKL/OPG ration with that in healthy persons. Gingival biopsies were obtained from subjects with clinically healthy periodontium (H) (N = 11) and patients with advanced chronic periodontitis (CP) (N = 14). Total RNA was isolated from the gingival samples and 1 microg RNA was reverse transcribed to cDNA, followed by polymerase chain reaction (PCR) using specific primers for OPG and RANKL. The efficiency of reverse transcription was verified by the amplification of the GAPDH gene. The intensity of RT-PCR products was analyzed by a densitometer and was normalized to the intensity of the band for the housekeeping gene GAPDH. Immunohistochemical evaluation of the RANKL and OPG expression was also performed. The expression of RANKL as well as of OPG was reduced in CP specimens in comparison to that of healthy persons in a statistical significant way. However, the RANKL/OPG ratio showed to be slightly elevated in CP compared to H specimens but this finding was not of statistical significance. The immunohistochemical analysis revealed a non-uniform expression pattern for both proteins. Although further investigation is needed to identify the specific role of RANKL and OPG protein in periodontitis progression, our data after SRP might indicate the possible involvement of these proteins in the activation of

    AbstractObjectiveTo determine the factors associated with change in bilirubin concentration 12 weeks after the initiation of an atazanavir (ATV)-containing antiretroviral regimen.MethodsWe performed a retrospective case note review of all patients prescribed ATV between January 2004 and October 2007 in a cohort of HIV infected subjects. Data collected included baseline demographics, hepatitis B and C serology, current antiretroviral therapy, baseline and week 12 routine bloods. The primary endpoint was the change in bilirubin concentration at 12 weeks after start of ATV. Multvariable linear regression was performed to assess the relationships between the change in bilirubin and variables of interest. Results: Eighty-three ATV-treated patients were included in the analysis of whom 46 (60.5%) were hepatitis C antibody positive. The median (interquartile range) change in bilirubin by week 12 was 16 (4, 22) umol\\/L; only 1 patient developed grade 4 hyperbilirubinaemia at week 12. After controlling for baseline bilirubin levels, HCV seropositivity and baseline ALP were associated with a smaller change in bilirubin over the 12 weeks with a trend towards lower increases in those receiving tenofovir. Sensitivity analyses reported similar associations with methadone use and injection drug use, when these variables replaced HCV sero-positivity in the model. Conclusion: Patients with hepatitis C co-infection experience smaller changes in bilirubin upon exposure to ATV. Although the underlying mechanism for this association remains unclear, these data support the safe use of this drug in this patient setting. Further research into the clinical predictors of ATV-related hyperbilirubinaemia is warranted.

    An efficient perturbational treatment of spin-orbit coupling within the framework of high-level multi-reference techniques has been implemented in the most recent version of the COLUMBUS quantum chemistry package, extending the existing fully variational two-component (2c) multi-reference configuration interaction singles and doubles (MRCISD) method. The proposed scheme follows related implementations of quasi-degenerate perturbation theory (QDPT) model space techniques. Our model space is built either from uncontracted, large-scale scalar relativistic MRCISD wavefunctions or based on the scalar-relativistic solutions of the linear-response-theory-based multi-configurational averaged quadratic coupled cluster method (LRT-MRAQCC). The latter approach allows for a consistent, approximatively size-consistent and size-extensive treatment of spin-orbit coupling. The approach is described in detail and compared to a number of related techniques. The inherent accuracy of the QDPT approach is validated by comparing c...

    The analytical capabilities of the 222-S Laboratory are tested against the requirements for an optional start up scenario of the Waste Treatment and Immobilization Plant on the Hanford Site. In this case, washed and in-tank leached sludge would be sent directly to the High Level Melter, bypassing Pretreatment. The sludge samples would need to be analyzed for certain key constituents in terms identifying melter-related issues and adjustment needs. The analyses on original tank waste as well as on washed and leached material were performed using five sludge samples from tanks 241-AY-102, 241-AZ-102, 241-AN-106, 241-AW-105, and 241-SY-102. Additionally, solid phase characterization was applied to determine the changes in mineralogy throughout the pre-treatment steps.

    Full Text Available BACKGROUND: The clinical correlations and significance of subnormal CD4 levels in HIV-negative patients with TB are unclear. We have determined CD4 cell levels longitudinally during anti-tuberculosis treatment (ATT in patients, with and without HIV co-infection, and their associations with clinical variables. METHOD: Adults diagnosed with TB (maximum duration of ATT for 2 weeks, and with no history of antiretroviral therapy (ART in HIV-positive subjects were included consecutively in eight out-patient clinics in Ethiopia. Healthy individuals were recruited for comparison at one of the study health centers. Data on patient characteristics and physical findings were collected by trained nurses following a structured questionnaire at inclusion and on follow-up visits at 2 and 6 months. In parallel, peripheral blood CD4 cell levels were determined. The evolution of CD4 cell levels during ATT was assessed, and the association between clinical characteristics and low CD4 cell levels at baseline was investigated using regression analysis. RESULTS: In total, 1116 TB patients were included (307 HIV-infected. Among 809 HIV-negative patients, 200 (25% had subnormal CD4 cell counts (<500 cells/mm(3, with <350 cells/mm(3 in 82 (10% individuals. CD4 cell levels increased significantly during the course of ATT in both HIV+ and HIV- TB-patients, but did not reach the levels in healthy subjects (median 896 cells/mm(3. Sputum smear status, signs of wasting (low mid upper arm circumference (MUAC, and bedridden state were significantly associated with low CD4 cell counts. CONCLUSION: A high proportion of Ethiopian TB patients have subnormal CD4 cell counts before starting treatment. Low CD4 cell levels are associated with smear positive disease and signs of wasting. The continuous increase of CD4 cell counts during the course of ATT suggest a reversible impact of active TB on CD4 cell homeostasis, which may be considered in interpretation of CD4 cell counts in HIV

    This paper deals with application of fuzzy intelligent systems in diagnosing severity level and recommending appropriate therapies for patients having Benign Prostatic Hyperplasia. Such an intelligent system can have remarkable impacts on correct diagnosis of the disease and reducing risk of mortality. This system captures various factors from the patients using two modules. The first module determines severity level of the Benign Prostatic Hyperplasia and the second module, which is a decision making unit, obtains output of the first module accompanied by some external knowledge and makes an appropriate treatment decision based on its ontology model and a fuzzy type-1 system. In order to validate efficiency and accuracy of the developed system, a case study is conducted by 44 participants. Then the results are compared with the recommendations of a panel of experts on the experimental data. Then precision and accuracy of the results were investigated based on a statistical analysis.

    It is well known that endocrine disrupting compounds (EDCs) present in wastewater treatment plant (WWTP) effluents interfere with reproduction in fish, including altered gonad development and induction of vitellogenin (Vtg), a female-specific egg yolk protein precursor produced in the liver. As a result, studies have focused on the effects of EDC exposure on the gonad and liver. However, impacts of environmental EDC exposure at higher levels of the hypothalamic-pituitary-gonad axis are less well understood. The pituitary gonadotropins, follicle-stimulating hormone (Fsh) and luteinizing hormone (Lh) are involved in all aspects of gonad development and are subject to feedback from gonadal steroids making them a likely target of endocrine disruption. In this study, the effects of WWTP effluent exposure on pituitary gonadotropin mRNA expression were investigated to assess the utility of Lh beta-subunit (lhb) as a biomarker of estrogen exposure in juvenile coho salmon (Oncorhynchus kisutch). First, a controlled 72-h exposure to 17α-ethynylestradiol (EE2) and 17β-trenbolone (TREN) was performed to evaluate the response of juvenile coho salmon to EDC exposure. Second, juvenile coho salmon were exposed to 0, 20 or 100% effluent from eight WWTPs from the Puget Sound, WA region for 72h. Juvenile coho salmon exposed to 2 and 10ng EE2L(-1) had 17-fold and 215-fold higher lhb mRNA levels relative to control fish. Hepatic vtg mRNA levels were dramatically increased 6670-fold, but only in response to 10ng EE2L(-1) and Fsh beta-subunit (fshb) mRNA levels were not altered by any of the treatments. In the WWTP effluent exposures, lhb mRNA levels were significantly elevated in fish exposed to five of the WWTP effluents. In contrast, transcript levels of vtg were not affected by any of the WWTP effluent exposures. Mean levels of natural and synthetic estrogens in fish bile were consistent with pituitary lhb expression, suggesting that the observed lhb induction may be due to

    Sulpiride (SULP), a substituted benzamide with high selectivity for D2-like dopamine receptors, has a chiral structure and is used in most countries as the racemate. In an open pilot study, we investigated 26 inpatients (13 female, 13 male) with schizophrenic or depressive disorder treated with SULP (mean daily dosage 64-1062 mg) administered orally, either as a monotherapy or as an add-on treatment to a stable and unchanged medication for 3-60 days. Serum levels of total SULP and of its enantiomers were measured by high-performance liquid chromatography (HPLC) procedures. Clinically relevant indicators of hepatic and renal function as well as retrospectively assessed clinical outcome parameters were correlated with serum levels of racemic SULP, L-SULP, D-SULP, and the L:D-SULP ratio. A significant correlation between mean daily dosage and serum levels of SULP, L-SULP, and D-SULP emerged (p < 0.05) which was not influenced by age, gender, diagnosis, hepatic, or renal function. The ratio of L:D-SULP serum levels was <1 (range 0.66-0.97) in all patients. A slight negative correlation between CGI improvement and the ratio of L:D-SULP (p < 0.10) and a positive correlation between racemic SULP concentrations and side-effects at endpoint was found (p < 0.05).

    The cytotoxic management of ectopic pregnancy using a single dose of intramuscular methotrexate injection has been well established as effective for a select number of women with unruptured tubal ectopic pregnancy where there are minimal symptoms. The purpose of this study was to create centile curves of serum β-hCG levels following successful treatment with a single dose of 50 mg/m(2) of intramuscular methotrexate to treat ectopic pregnancy. Data were retrieved from women treated at the Royal Women's Hospital for ectopic pregnancy between 2006 and 2012. Only women with minimal symptoms, initial serum β-hCG ≤5000 IU/L and ectopic mass size of ≤35 mm on ultrasound were included. Two hundred and fifty-three cases of ectopic pregnancy were analysed. Initial β-hCG of women in the study ranged from 18 to 3995 IU/L with a median of 497 (25th to 75th centiles; 222-1160) IU/L. The median levels of β-hCG levels at day 4, 7 and 14 postmethotrexate injection were 73.8, 47.2 and 10.4% of the initial β-hCG level, respectively. The 90th centiles of β-hCG levels at day 4, 7 and 14 were 124.7, 93.8 and 40.0% of initial β-hCG level, respectively. Whilst no comparison with those unsuccessfully treated was made, pending further validation studies, the use of these curves may reduce the reliance on specialist units and streamline care for many women with ectopic pregnancy, such as those whose β-hCG regress in line with centile values without crossing a certain threshold. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Exercise exerts antidepressant effects in humans and rodent models of affective disorders. These effects may be mediated by the upregulation of endogenous factors that exert antidepressant actions. The physiological functions and behavioral actions of the neuropeptide galanin (GAL) suggest antidepressant activity. Previous studies have shown that various modes of exercise elevate GAL gene expression in the locus coeruleus (LC) in rats. The present experiments examined the interaction between voluntary exercise and antidepressant pharmacotherapy. Male Sprague-Dawley rats were provided access to activity wheels (exercise condition) or inoperative wheels (sedentary condition) for 28 days. Rats in each group were injected with clomipramine (10mg/kg/day) or vehicle throughout this period (for 3 weeks). Prepro-GAL mRNA in the LC was measured by in situ hybridization histochemistry. Exercise and clomipramine treatment significantly elevated GAL gene expression, though prepro-GAL mRNA levels in rats receiving both interventions did not differ from sedentary controls that received vehicle. Prepro-GAL mRNA levels were significantly correlated with running distance. The results further implicate a role for GAL in the antidepressant effects of exercise and pharmacotherapy, though the mechanisms through which these treatments influence GAL gene expression appear to differ significantly.

    In this study, the influence of antidotal treatment of tabun poisoning on cognitive function, in the case of low-level tabun exposure, was studied. The impairment of cognitive function was evaluated by the measurement of spatial learning and memory in rats poisoned with a sublethal dose of tabun and treated with atropine alone or in combination with newly developed oximes {K027 [1-(4-hydroxyiminomethyl- pyridinium)-3-(4-carbamoylpyridinium) propane dibromide] and K048 [1-(4-hydroxyimino- methylpyridinium)-3-(4-carbamoylpyridinium) butane dibromide]} or currently available oxime (trimedoxime), using the Morris water maze. While atropine alone caused an impairment of studied cognitive functions, the addition of an oxime to atropine contributes to the improvement of cognitive performance of treated tabun-poisoned rats regardless of the type of oxime. The differences in the ameliorative effects of oximes on atropine-induced mnemonic deficits were not significant. Therefore, each low-level nerve agent exposure should be treated by complex antidotal treatment consisting of anticholinergic drug and oxime.

    Full Text Available An experimental device for plasma treatment of low and intermediate level radioactive waste was built and tested in several design variations. The laboratory device is designed with the intention to study the general effects and difficulties in a plasma incineration set-up for the further future development of a larger scale pilot plant. The key part of the device consists of a novel microwave plasma torch driven by 200 W electric power, and operating at atmospheric pressure. It is a specific design characteristic of the torch that a high peak temperature can be reached with a low power input compared to other plasma torches. Experiments have been carried out to analyze the effect of the plasma on materials typical for operational low-level wastes. In some preliminary cold tests the behavior of stable volatile species e. g., caesium was investigated by TXRF measurements of material collected from the oven walls and the filtered off-gas. The results help in improving and scaling up the existing design and in understanding the effects for a pilot plant, especially for the off-gas collection and treatment.

    Ketamine and lithium both inhibit glycogen synthase kinase 3. In addition, lithium and ketamine have synergistic antidepressant-like effects at individually subeffective doses in rodents. We hypothesized that ketamine's antidepressant effects would be improved by therapeutic doses of lithium versus valproate and that serum lithium levels would positively correlate with ketamine's antidepressant efficacy. Thirty-six patients with treatment-resistant bipolar depression maintained on therapeutic-dose lithium (n = 23, 0.79 ± 0.15 mEq/L) or valproate (n = 13, 79.6 ± 12.4 mg/mL) received 0.5 mg/kg ketamine infusion in a randomized, double-blind, placebo-controlled, crossover trial. The primary depression outcome measure-the Montgomery-Åsberg Depression Rating Scale (MADRS)-was assessed before infusion and at numerous postinfusion time points. Both lithium (F 1,118 = 152.08, p lithium and valproate levels did not correlate with ketamine's antidepressant efficacy. Although the study was potentially underpowered, our results suggest that lithium may not potentiate ketamine's antidepressant efficacy in treatment-resistant bipolar depression.

    Alkylmethoxypyrazines (MPs) are a class of compounds that can elicit undesirable aroma and flavor characteristics in wine, and resist remediation using traditional wine making approaches. MPs are grape-derived constituents as well as contaminants from Coccinellidae beetles present during wine processing; the latter eliciting an off-flavor referred to as 'ladybug taint'. In this study we investigated the capacity of two plastic polymers-one silicone-based, the other polylactic acid-based-applied with varying surface areas to reduce concentrations of isopropylmethoxypyrazine (IPMP), sec-butylmethoxypyrazine (SBMP) and isobutylmethoxypyrazine (IBMP) in a Merlot wine using multi-dimensional gas chromatography coupled with mass spectrometry and headspace solid phase microextraction (SPME-MDGCMS). The impact of treatments on the sensory characteristics of the wine (descriptive analysis) and volatile aroma compounds (VOCs) (SPME-MDGCMS) was also investigated. Results showed substantial reductions for all of the target odorants: up to 38%, 44% and 39% for IPMP, SBMP and IBMP, respectively, for the silicone polymer, and up to 75%, 78% and 77% for IPMP, SBMP and IBMP, respectively, for the polylactic acid polymer. These polymers had no or minimal effect on VOCs at applications of 200 cm²/L for silicone or for all polylactic acid treatments. Sensory impacts were less clear, but generally showed minimal effect from the treatments. Taken overall, the data confirm the utility of both polylactic acid and silicone polymers in reducing elevated levels of grape-derived MPs, as well as potentially improving wine contaminated by ladybug taint.

    The Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) obtained a sample of 1493 chronic schizophrenia patients. The European First Episode Schizophrenia Trial (EUFEST) studied a sample of 498 patients. We have combined these two samples to study the predictors and correlates of adherence to treatment. Here we report on adherence to pharmacological treatment at the six and twelve month assessments of these trials with a combined subsample of 1154 schizophrenia patients. Individual patients׳ data were used for analyses. We used logistic regression to examine the effects of substance use, akathisia, parkinsonism, dyskinesia, hostility, and insight on pharmacological adherence. The results showed that reduced adherence to pharmacological treatment was associated with substance use (p=0.0003), higher levels of hostility (p=0.0002), and impaired insight (p<0.0001). Furthermore, poor adherence to study medication was associated with earlier discontinuation in the combined data. The clinical implications of the results point to the importance of routine assessments and interventions to address patients׳ insight and comorbid substance use and the establishment of therapeutic alliance.

    Full Text Available To increase the yield of the wafer-level Cu-Cu thermo-compression bonding method, certain surface pre-treatment methods for Cu are studied which can be exposed to the atmosphere before bonding. To inhibit re-oxidation under atmospheric conditions, the reduced pure Cu surface is treated by H2/Ar plasma, NH3 plasma and thiol solution, respectively, and is covered by Cu hydride, Cu nitride and a self-assembled monolayer (SAM accordingly. A pair of the treated wafers is then bonded by the thermo-compression bonding method, and evaluated by the tensile test. Results show that the bond strengths of the wafers treated by NH3 plasma and SAM are not sufficient due to the remaining surface protection layers such as Cu nitride and SAMs resulting from the pre-treatment. In contrast, the H2/Ar plasma–treated wafer showed the same strength as the one with formic acid vapor treatment, even when exposed to the atmosphere for 30 min. In the thermal desorption spectroscopy (TDS measurement of the H2/Ar plasma–treated Cu sample, the total number of the detected H2 was 3.1 times more than the citric acid–treated one. Results of the TDS measurement indicate that the modified Cu surface is terminated by chemisorbed hydrogen atoms, which leads to high bonding strength.

    The treatment of pityriasis versicolor by the topical application of selenium sulfide 1% was studied in two groups of patients. Diagnosis and response to therapy was determined by clinical observation. Wood's light fluorescence, and direct microscopic examination. The efficacy of three different therapeutic regimes was studied in one group by the application of the drug to the entire skin for either five minutes, fifteen minutes, or twelve hours for eighteen days. Each method proved equally effective in resolving the infection. Therefore, the cutaneous application of selenium sulfide 1 % for five minutes daily for eighteen days is the recommended treatment for pityriasis versicolor. The percutaneous absorption of selenium sulfide was also studied in another groups who applied the drug to the entire skin for five minutes for eighteen days. Fluorimetric analysis of urinary samples collected on the third and thirteenth days of treatment revealed no significant increase in the excretion of selenium as compared to pretreatment levels. Systemic toxicity was not observed in any of the patients treated. The results suggest that the selenium sulfide is absorbed poorly from the skin and is a safe and effective therapy for pityriasis versicolor.

    Full Text Available Obesity is one of the risk factors for developing lymphedema following breast cancer treatment. We prospectively enrolled 140 women and followed the participants for 12 months after surgery to investigate patterns of obesity and lymph fluid level in the first year of cancer treatment. Electrical bioimpedance devices were used to measure weight, BMI, and percent of body fat as well as lymph fluid level. General instructions were given to the participants on maintaining pre-surgery weight. Among the 140 participants, 136 completed the study with 2.9% attrition. More than 60% of the participants were obese (30.8% or overweight (32.4%, while only two participants were underweight and about 35% had normal weight. This pattern of obesity and overweight was consistent at 4–8 weeks and 12 months post-surgery. At 12 months post-surgery, the majority of the women (72.1% maintained pre-surgery weight and 15.4% had >5% weight loss; 12.5% of the women increase >5% of their weight. Significantly more patients in the obesity group had lymphedema defined by L-Dex ratio >7.1 than those in the normal/underweight and overweight group at pre-surgery and 4–8 weeks post-surgery. There was a trend of more patients in the obesity group had L-Dex ratio >7.1 at 12 months post-surgery. Obesity and overweight remain among women at the time of cancer diagnosis and the patterns of obesity and overweight continue during the first year of treatment. General instructions on having nutrition-balanced and portion-appropriate diet and physical activities daily or weekly can be effective to maintain pre-surgery weight.

    Foot ulcers are serious complications of diabetes mellitus (DM) and are known to be resistant to conventional treatment. This study was conducted to evaluate the efficacy of low-level laser therapy (LLLT) for the treatment of diabetic foot ulcers in a tertiary care centre (Department of Surgery, Mahatma Gandhi Memorial Medical College and Maharaja Yashwantrao Hospital, A.B. Road, Indore). A total of 30 patients with type 2 DM having Meggitt-Wagner grade I foot ulcers of more than 6 weeks duration with negative culture were studied. Patients were randomized into two groups of 15 each. Patients in study group received LLLT (660 ± 20 nm, 3 J/cm(2)) along with conventional therapy and those in control group were treated with conventional therapy alone. The primary outcome measure was the absolute and relative wound size reduction at 2 weeks compared to the baseline parameter. Percentage ulcer area reduction was 37 ± 9% in the LLLT group and 15 ± 5.4% in the control group (p < 0.001). For ∼75% of wounds of the treatment group, wound area reduction of 30-50% was observed. In contrast, for the control group, ∼80% of wounds showed a wound area reduction of <20% on day 15. Further, the wounds with initial wound area 1000-2000 mm(2) seems to have better final outcome than the groups with larger areas. The treated groups showed higher amount of granulation than the control group. The results suggest that LLLT is beneficial as an adjunct to conventional therapy in the treatment of diabetic foot ulcers.

    Soil contaminated with hydrocarbons is a current problem of great importance. These contaminants may be toxic, can retain water and block gas exchange with the atmosphere, which produces a poor-quality soil unsuitable for ecological health. Electroremediation is among the treatments for the removal of such contaminants. In this research, a pilot-level electroremediation test was applied using a circular arrangement of electrodes with a Ti cathode at the middle of the cell surrounded by six IrO2-Ta2O5 | Ti anodes. The presence of an NaOH electrolyte helps to develop the electromigration and electro-osmosis of gasoline molecules (at 1126 mg kg-1) surrounded by Na+ ions. The hydrocarbons are directed towards the cathode and subsequently removed in an aqueous Na+ - hydrocarbon solution, and the -OH migrates to the anode. During electrokinetic treatment, the physicochemical characteristics of the soil close to either the cathode or anode and at the half-cell were evaluated during the three weeks of treatment. During that time, more than 80% of hydrocarbons were removed. Hydrocarbons removed by the electrokinetic treatment of gasoline-polluted soil were collected in a central wastewater compartment and subsequently treated with a Fenton-type advanced oxidation process. This achieved more than 70% mineralization of the hydrocarbons to CO2 and H2O within 1.5 h; its low toxicity status was verified using the Deltatox® kit test. With this approach, the residual water complied with the permissible limits of COD, pH, and electrical conductivity for being discharged into water bodies, according to Mexican norm NOM-001-SEMARNAT-1996.

    Background Lipopolysaccharide-binding protein (LBP) has been reported to associate with metabolic diseases, such as obesity, diabetes, and non-alcoholic fatty liver disease. Since chronic hepatitis C virus (HCV) infection is associated with metabolic derangements, the relationship between LBP and HCV deserves additional studies. This study aimed to determine the serum LBP level in subjects with or without HCV infection and investigate the change of its level after anti-viral treatments with or without interferon. Methods and Findings We recruited 120 non-HCV subjects, 42 and 17 HCV-infected subjects respectively treated with peginterferon α-2a/ribavirin and direct-acting antiviral drugs. Basic information, clinical data, serum LBP level and abdominal ultrasonography were collected. All the subjects provided written informed consent before being enrolled approved by the Research Ethics Committee of the National Taiwan University Hospital. Serum LBP level was significantly higher in HCV-infected subjects than non-HCV subjects (31.0 ± 8.8 versus 20.0 ± 6.4 μg/mL; p-value < 0.001). After multivariate analyses, LBP at baseline was independently associated with body mass index, hemoglobin A1c, alanine aminotransferase (ALT) and HCV infection. Moreover, the baseline LBP was only significantly positively associated with ALT and inversely with fatty liver in HCV-infected subjects. The LBP level significantly decreased at sustained virologic response (27.4 ± 6.6 versus 34.6 ± 7.3 μg/mL, p-value < 0.001; 15.9 ± 4.4 versus 22.2 ± 5.7 μg/mL, p-value = 0.001), regardless of interferon-based or -free therapy. Conclusions LBP, an endotoxemia associated protein might be used as an inflammatory biomarker of both infectious and non-infectious origins in HCV-infected subjects. PMID:28107471

    Previous studies indicated that reduced androgen levels may contribute to both physical and cognitive disorders in men, including Alzheimer's disease. New drug candidates for Alzheimer's disease in patients with androgen deficiency should ideally be able to act not only on multiple brain targets but also to correct impaired endocrine functions in hypogonadal men with Alzheimer's disease. Ropren(®) is one such candidate for the treatment of Alzheimer's disease in men with an imbalance of androgens. Accordingly, the aim of the current study was to examine the effects of long-term Ropren(®) administration (8.6mg/kg, orally, once daily, for 28 days) on the anxiety-like behavior and monoamines levels in the rat hippocampus using a β-amyloid (25-35) rat model of Alzheimer's disease following gonadectomy. Ropren(®) was administered to the gonadectomized (GDX) rats and GDX rats treated with testosterone propionate (TP, 0.5mg/kg, subcutaneous, once daily, for 28 days). Anxiety-like behavior was assessed in the elevated plus maze (EPM) and the light-dark test (LDT), locomotor and grooming activities were assessed in the open field test (OFT). Ropren(®) alone or in combination with TP-induced anxiolytic effects as evidenced in the EPM and in the LDT and increased locomotor activity in the OFT. Additionally, it was observed that dopamine (DA) and serotonin (5-HT) levels increased while 5-hydroxyindoleacetic acid (5-HIAA)/5-HT ratio in the hippocampus decreased. Our results indicate that Ropren(®) has a marked anxiolytic-like action due to an increase in the monoamines levels in the experimental rat model of Alzheimer's disease with altered levels of androgens.

    This study measured greenhouse gas emissions (GHG) by Facultative Ponds on Wastewater Treatment Plants. The most studied GHGs include CO2, CH4and N2O. The level of GHG (CO2, CH4 and N2O) emissions by WWTPs in Australian-type stabilization ponds was measured in the city of Lins (22º21'S, 49º50'W), state of São Paulo (SP), Brazil. GHG collection was carried outusing a collection chamber installed at the center of the facultative pond's final third. The effluent's pH and temperature (ET) were registered by probes, and meteorological information regarding air temperature (AT) and solar radiation (SR) were obtained from INMET, Brazil. GHG collection was carried out for 72 consecutive hours in June 2014, on an hourly basis, once every 5 minutes, for the first 30 minutes, and once every 10 minutes from 30 to 50 minutesand subsequently analyzed by gas chromatograph (GC).After three days of data collection, the average AT, SR, ET and pH values were, respectively, 18oC, 2583kJm-2, 23oC and 8.2. Average values for GHG emission levels (CH4, CO2 and N2O) were 79.01; 100.65 and 0.0 mg m-2 h-1, respectively. GHG emission levels were divided into light periods (morning, afternoon and evening)in order to verify the periods with the highest GHG emissions.The highest CH4 emission levels were measured between morning and early afternoon. The maximum CO2 emissions were observed from evening to early morning. N2O emissions were constant and values were close to the ones found in the atmosphere, which shows the emission of N2O by facultative ponds does not contribute to greenhouse gases emissions.The results enabled us to characterize and quantify GHG emission levels per Facultative Pond on Wastewater Treatment Plant.

    OBJECTIVE: The aim of this study was to (1) observe the extent to which hemodynamic and glucose measurements change in patients submitted to a dental procedure with and without a local anesthetic and a vasoconstrictor (LAVA; 2% mepivacaine with adrenaline 1∶100,000) and (2) correlate those parameters with the patients' anxiety levels. METHOD: This was an unblinded, random, prospective, and observational study with paired groups. Patients were evaluated during two different consultations during which they either did or did not receive a local anesthetic/vasoconstrictor. RESULTS: Thirty‐seven patients ranging in age from 18 to 45 years (mean 30.4 ± 5.5 years) were evaluated. Hemodynamic parameters, including systolic blood pressure, diastolic blood pressure, heart rate, and glucose levels, did not change significantly in healthy patients, regardless of whether a LAVA was administered during the dental treatment. CONCLUSION: The patients' anxiety statuses neither varied significantly nor showed any correlation with the studied hemodynamic parameters and glucose levels, regardless of whether local anesthetics were used.

    Background Recent research suggested that obstructive sleep apnea syndrome (OSAS) might be independently associated with hypoadiponectinemia, which was linked to some complications of OSAS, such as hypertension, diabetes,etc. This study was conducted to investigate the effect of continuous positive airway pressure (CPAP) treatment on changes of both serum adiponectin levels and mean arterial pressure and their possible links in male OSAS patients.Methods Twenty-three adult male patients with moderate-to-severe OSAS but without obesity, coronary heart disease and diabetes were recruited. Their blood sampleswere collected and moming mean arterial pressure (MAP) was measured before CPAP treatment and on day 3, 7, 14 of CPAP treatment respectively. The serum adiponectin concentration was tested with radioimmunoassay.Results Compared with the serum adiponectin level before CPAP treatment, no significant change was found in OSAS patients on day 3 and day 7 of CPAP treatment (P>0.05). It was not until day 14 of CPAP treatment did a significant elevation in serum adiponectin level occur (P<0.01). Meanwhile, the MAP showed no statistically significant difference among its levels before CPAP, on day 3 and day 7 of CPAP treatment (P>0.05). However, on day 14 of CPAP treatment,a significantly lower MAP than that obtained before treatment was observed (P<0.05).Conclusions CPAP treatment can gradually reverse hypoadiponectinemia and reduce MAP in OSAS patients.Hypoadiponectinemia might be involved in the pathogenesis of OSAS-mediated hypertension.

    To evaluate a center of rotation of angulation (CORA)-based leveling osteotomy for cranial cruciate ligament injury in dogs. Retrospective case series. Dogs (n=70). Medical records (March 2011 to March 2012) of dogs diagnosed with a cranial cruciate ligament (CCL) injury treated with a CORA-based leveling osteotomy and stabilized using a bone plate and headless compression screw were reviewed. Radiographs were reviewed for tibial plateau angle and radiographic healing at final evaluation graded on a 5-point scale. Follow-up for a minimum of 6 months postoperatively was conducted by owner completion of a questionnaire regarding their dog's function after surgery. Based on owner responses, clinical outcomes were established. CORA-based leveling osteotomy was used for 70 stifles with CCL injury. The mean time to final radiographic recheck was 107 days (range, 32-424 days). Radiographic healing scores were 42 dogs (69%) with grade 4, 17 dogs (28%) with grade 3, and 2 dogs (3%) with grade 2. The mean time to follow-up was 11.9 months (range 6-18 months). Fifty-four of the 70 (77%) dogs had full function, 13 (19%) had acceptable function, and 3 (4%) had unacceptable function. Complications occurred in 11 stifles (16%), including 3 incisional, 6 late-onset meniscal tears, and 2 implant related. The described method of a CORA-based leveling osteotomy can be successfully performed for treatment of CCL injury in dogs. At the time of mid-term and long-term owner follow-up, most dogs in this case series had returned to full function. © Copyright 2016 by The American College of Veterinary Surgeons.

    Background The relationship between symptom elimination and normalization of esophageal acid level of gastroesophageal reflux disease (GERD) on proton-pump inhibitor (PPI) therapy has been questioned. This study aimed to evaluate the relationship between symptom response and gastro-esophageal acidity control in Chinese patients with GERD on esomeprazole therapy, and to assess the role of 24-hour esophageal pH-metry after therapy in GERD patients.Methods GERD patients with typical reflux symptoms were enrolled and received esomeprazole 40 mg once daily for 4 weeks. Patients with positive baseline 24-hour esophageal pH-metry were divided into two groups depending on an additional dual-channel 24-hour pH-metry after treatment. The pH- group achieved normalization of esophageal pH level whereas the pH+ group did not.Results Of the 80 patients studied, 76 had abnormal baseline esophageal pH levels. Of these, 90% (52/58) of symptom-free patients and 67% (12/18) of symptom-persistent patients achieved esophageal pH normalization after therapy (P=0.030). The mean post-therapy gastric nocturnal percent time of pH <4.0 was significantly higher in pH+group than that in pH- group (P <0.001) after therapy. The multivariate regression analysis identified hiatus hernia (P<0.001) and persistent reflux symptom (P=0.004) were two independent factors predicting the low post-therapy esophageal pH level.Conclusions Symptom elimination is not always accompanied by esophageal pH normalization, and vice verse.Esophageal pH-metry is recommended for GERD patients with hiatus hernia or with persistent reflux symptoms after PPI therapy.

    Improved centralized treatment methods are needed in the management of liquid low-level waste (LLLW) at Oak Ridge National Laboratory (ORNL). LLLW, which usually contains radioactive contaminants at concentrations up to millicurie-per-liter levels, has accumulated in underground storage tanks for over 10 years and has reached a volume of over 350,000 gal. These wastes have been collected since 1984 and are a complex mixture of wastes from past nuclear energy research activities. The waste is a highly alkaline 4-5 M NaNO{sub 3} solution with smaller amounts of other salts. This type of waste will continue to be generated as a consequence of future ORNL research programs. Future LLLW (referred to as newly generated LLLW or NGLLLW) is expected to a highly alkaline solution of sodium carbonate and sodium hydroxide with a smaller concentration of sodium nitrate. New treatment facilities are needed to improve the manner in which these wastes are managed. These facilities must be capable of separating and reducing the volume of radioactive contaminants to small stable waste forms. Treated liquids must meet criteria for either discharge to the environment or solidification for onsite disposal. Laboratory testing was performed using simulated waste solutions prepared using the available characterization information as a basis. Testing was conducted to evaluate various methods for selective removal of the major contaminants. The major contaminants requiring removal from Melton Valley Storage Tank liquids are {sup 90}Sr and {sup 137}Cs. Principal contaminants in NGLLLW are {sup 9O}Sr, {sup 137}Cs, and {sup 106}Ru. Strontium removal testing began with literature studies and scoping tests with several ion-exchange materials and sorbents.

    Full Text Available Alkylmethoxypyrazines (MPs are a class of compounds that can elicit undesirable aroma and flavor characteristics in wine, and resist remediation using traditional wine making approaches. MPs are grape-derived constituents as well as contaminants from Coccinellidae beetles present during wine processing; the latter eliciting an off-flavor referred to as ‘ladybug taint’. In this study we investigated the capacity of two plastic polymers—one silicone-based, the other polylactic acid-based—applied with varying surface areas to reduce concentrations of isopropylmethoxypyrazine (IPMP, sec-butylmethoxypyrazine (SBMP and isobutylmethoxypyrazine (IBMP in a Merlot wine using multi-dimensional gas chromatography coupled with mass spectrometry and headspace solid phase microextraction (SPME-MDGCMS. The impact of treatments on the sensory characteristics of the wine (descriptive analysis and volatile aroma compounds (VOCs (SPME-MDGCMS was also investigated. Results showed substantial reductions for all of the target odorants: up to 38%, 44% and 39% for IPMP, SBMP and IBMP, respectively, for the silicone polymer, and up to 75%, 78% and 77% for IPMP, SBMP and IBMP, respectively, for the polylactic acid polymer. These polymers had no or minimal effect on VOCs at applications of 200 cm2/L for silicone or for all polylactic acid treatments. Sensory impacts were less clear, but generally showed minimal effect from the treatments. Taken overall, the data confirm the utility of both polylactic acid and silicone polymers in reducing elevated levels of grape-derived MPs, as well as potentially improving wine contaminated by ladybug taint.

    The aim of the present study was to assess the effect of low-level laser therapy (LLLT) in the treatment of burning mouth syndrome (BMS). A diode laser was used in 78 BMS patients who were randomly assigned into four groups: IR1W, n=20 (830 nm, 100 mW, 5 J, 176 J/cm2, 50 s, LLLT weekly sessions, 10 sessions); IR3W, n=20 (830 nm, 100 mW, 5 J, 176 J/cm2, 50 s, three LLLT weekly sessions, 9 sessions); red laser, n=19 (685 nm, 35 mW, 2 J, 72 J/cm2, 58 s, three LLLT weekly sessions, 9 sessions); and control-group (CG), n=19. Symptoms were assessed at the end of the treatment and eight weeks later; quality of life related to oral health was assessed using the Oral Health Impact Profile (OHIP-14). Statistical analysis was carried out using repeated measures analysis of variance followed by the posthoc Tukey test. There was significant reduction of the symptoms in all groups at the end of the treatment, which was maintained in the follow-up. The scores of the IR1W and IR3W laser groups differed significantly from those of the CG. There was also a decrease in the OHIP-14 scores in the four groups. The IR3W laser group scores differed significantly from those of the CG. LLLT reduces the symptoms of BMS and may be an alternative therapeutic strategy for the relief of symptoms in patients with BMS.

    Background. Decentralization of antiretroviral therapy (ART) services is a key strategy to achieving universal access to treatment for people living with HIV/AIDS. Our objective was to assess clinical and laboratory outcomes within a decentralized program in Nigeria. Methods. Using a tiered hub-and-spoke model to decentralize services, a tertiary hospital scaled down services to 13 secondary-level hospitals using national and program guidelines. We obtained sociodemographic, clinical, and immunovirologic data on previously antiretroviral drug naïve patients aged ≥15 years that received HAART for at least 6 months and compared treatment outcomes between the prime and satellite sites. Results. Out of 7,747 patients, 3729 (48.1%) were enrolled at the satellites while on HAART, prime site patients achieved better immune reconstitution based on CD4+ cell counts at 12 (P < 0.001) and 24 weeks (P < 0.001) with similar responses at 48 weeks (P = 0.11) and higher rates of viral suppression (<400 c/mL) at 12 (P < 0.001) and 48 weeks (P = 0.03), but similar responses at 24 weeks (P = 0.21). Mortality was 2.3% versus 5.0% (P < 0.001) at prime and satellite sites, while transfer rate was 8.7% versus 5.5% (P = 0.001) at prime and satellites. Conclusion. ART decentralization is feasible in resource-limited settings, but efforts have to be intensified to maintain good quality of care.

    An efficient perturbational treatment of spin-orbit coupling within the framework of high-level multi-reference techniques has been implemented in the most recent version of the COLUMBUS quantum chemistry package, extending the existing fully variational two-component (2c) multi-reference configuration interaction singles and doubles (MRCISD) method. The proposed scheme follows related implementations of quasi-degenerate perturbation theory (QDPT) model space techniques. Our model space is built either from uncontracted, large-scale scalar relativistic MRCISD wavefunctions or based on the scalar-relativistic solutions of the linear-response-theory-based multi-configurational averaged quadratic coupled cluster method (LRT-MRAQCC). The latter approach allows for a consistent, approximatively size-consistent and size-extensive treatment of spin-orbit coupling. The approach is described in detail and compared to a number of related techniques. The inherent accuracy of the QDPT approach is validated by comparing cuts of the potential energy surfaces of acrolein and its S, Se, and Te analoga with the corresponding data obtained from matching fully variational spin-orbit MRCISD calculations. The conceptual availability of approximate analytic gradients with respect to geometrical displacements is an attractive feature of the 2c-QDPT-MRCISD and 2c-QDPT-LRT-MRAQCC methods for structure optimization and ab inito molecular dynamics simulations.

    The contamination level of four phthalates in untreated and treated wastewater of fifteen wastewater treatment plants (WWTPs) and their fate in a full scale sequencing batch reactor (SBR) based WWTP was evaluated in this study. The four phthalates were diethyl phthalate (DEP), dibutyl phthalate (DBP), benzylbutyl phthalate (BBP) and diethylhexyl phthalate (DEHP). All compounds were present in untreated wastewater with DEHP being present in the highest mean concentration of 28.4 ± 5.3 μg L(-1). The concentration was in the range of 7.3 μg L(-1) (BBP) to 28.4 μg L(-1) (DEHP) in untreated wastewater and 1.3 μg L(-1) (DBP) to 2.6 μg L(-1) (DEHP) in treated wastewater. The nutrient removal process and advance tertiary treatment based WWTPs showed the highest phthalate removal efficiencies of 87% and 93%, respectively. The correlation between phthalate removal and conventional performance of WWTPs was positive. Fate analysis of these phthalates in a SBR based WWTP showed that total removal of the sum of phthalates in a primary settling tank and SBR was 84% out of which 55% is removed by biodegradation and 29% was removed by sorption to primary and secondary sludge. The percentage removal of four phthalates in primary settling tanks was 18%. Comparison of the diluted effluent DEHP concentration with its environmental quality standards showed that the dilution in an effluent receiving water body can reduce the DEHP emissions to acceptable values.

    CuO nanoparticles (NPs) are released into wastewater due to the widespread use and generation as by-product in various applications (e.g. semiconductor manufacturing). However, information on the behavior and impact of CuO NPs on wastewater treatment processes is very limited. The objective of this study was to evaluate the fate and long-term effect of CuO NPs (average size = 37 nm) on high-rate anaerobic bioreactors. A laboratory-scale upflow anaerobic sludge blanket reactor was operated with a synthetic wastewater containing low concentrations of CuO NPs (1.4 mg Cu L(-1)) and a mixture of volatile fatty acids for 107 days. CuO NPs were largely removed during anaerobic treatment and on the average only 20-32% of the NPs fed to the reactor escaped with the effluent. Scanning electron microscopy and chemical analysis confirmed that CuO NPs were partitioned into the anaerobic sludge. While short-term exposure to CuO NPs (1.4 mg Cu L(-1)) only caused minor inhibition to methanogenesis, extended exposure caused severe toxicity and reduced the acetoclastic methanogenic activity by more than 85%. Moreover, the reactor performance was completely disrupted and the methane production decreased by more than 50%. The study is the first to demonstrate a significant long-term effect of low levels of CuO NPs on methanogenesis.

    The aim of this study was to evaluate the diagnostic value of serum mannose-binding lectin (MBL) and plasma soluble urokinase plasminogen activator receptor (SuPAR) levels in monitoring the treatment in patients with brucellosis, by comparing their levels before and after treatment with the values obtained from healthy control group. Thirty brucellosis patients (mean age: 25.8 ± 12.2 years; 15 were male) and 28 healthy controls (mean age: 29.3 ± 12.3 years; 15 were male) were included in the study. Patients were diagnosed with brucellosis according to the characteristic clinical findings and by brucella standard tube agglutination test (SAT) titer ≥ 1/160 and/or blood culture positivity. Serum MBL (Antibodyshop, Denmark) and plasma SuPAR (Virogates, Denmark) levels were investigated with commercial ELISA kits. In our study, no statistical significance was observed between the pre-treatment (13.8 ± 13.4 ng/ml) and post-treatment (12.4 ± 13.1 ng/ml) MBL levels of the patient group and MBL levels of the control group (16.5 ± 14.8 ng/ml) (p> 0.05). Moreover, the mean SuPAR levels measured in pre-treatment and post-treatment plasma samples of the brucellosis patients was 5.1 ± 1.9 ng/ml and 2.9 ± 1.3 ng/ml, respectively, while the mean SuPAR level was 1.8 ± 0.5 ng/ml in the control group. The difference between mean SuPAR levels of patients in pre- and post-treatment samples was found statistically significant (p 0.001). In conclusion, plasma SuPAR level would be a useful marker for the diagnosis and treatment follow up of the patients with brucellosis.

    The full-scale, room-temperature Hanford Tank Waste Treatment and Immobilization Plant (WTP) High-Level Waste (HLW) melter riser test system was successfully operated with silicone oil and magnetite particles at a loading of 0.1 vol %. Design and construction of the system and instrumentation, and the selection and preparation of simulant materials, are briefly reviewed. Three experiments were completed. A prototypic pour rate was maintained, based on the volumetric flow rate. Settling and accumulation of magnetite particles were observed at the bottom of the riser and along the bottom of the throat after each experiment. The height of the accumulated layer at the bottom of the riser, after the first pouring experiment, approximated the expected level given the solids loading of 0.1 vol %. More detailed observations of particle resuspension and settling were made during and after the third pouring experiment. The accumulated layer of particles at the bottom of the riser appeared to be unaffected after a pouring cycle of approximately 15 minutes at the prototypic flow rate. The accumulated layer of particles along the bottom of the throat was somewhat reduced after the same pouring cycle. Review of the time-lapse recording showed that some of the settling particles flow from the riser into the throat. This may result in a thicker than expected settled layer in the throat.

    Full Text Available OBJECTIVES: The aim of this cohort study was to examine the role of the chemokine (C-X-C motif ligand 9 (CXCL9 on nasopharyngeal carcinoma (NPC. MATERIALS & METHODS: Sera from 205 NPC patients and 231 healthy individuals, and 86 NPC tumor samples were enrolled. CXCL9 expression in tissue samples was analyzed by quantitative real-time PCR and immunohistochemistry. CXCL9 serum concentrations were measured by enzyme-linked immunosorbent assay. RESULTS: CXCL9 expression was significantly higher in tumors than in normal epithelium. CXCL9 serum concentrations were also significantly higher in NPC patients compared to those in healthy individuals (516.8±617.6 vs. 170.7±375.0 pg/mL, P290 pg/mL, median before treatment had worse prognoses for overall survival and disease-free survival (P = 0.045 and P = 0.008, respectively. Multivariate logistic regression analyses also indicated that higher CXCL9 serum levels were an independent prognostic factor for disease-free survival (P = 0.015. CONCLUSION: Our study demonstrated that CXCL9 is associated with tumor burden and aggressiveness of NPC tumors and the serum level of this ligand may be useful as a prognostic indicator.

    Abstract Problem Despite the Government’s effort to expand services to district level, it is still hard for people living with HIV to access antiretroviral treatment (ART) in rural Zambia. Strong demands for expanding ART services at the rural health centre level face challenges of resource shortages. Approach The Mumbwa district health management team introduced mobile ART services using human resources and technical support from district hospitals, and community involvement at four rural health centres in the first quarter of 2007. This paper discusses the uptake of the mobile ART services in rural Mumbwa. Local setting Mumbwa is a rural district with an area of 23 000 km2 and a population of 167 000. Before the introduction of mobile services, ART services were provided only at Mumbwa District Hospital. Relevant changes The mobile services improved accessibility to ART, especially for clients in better functional status, i.e. still able to work. In addition, these mobile services may reduce the number of cases “lost to follow-up”. This might be due to the closer involvement of the community and the better support offered by these services to rural clients. Lessons learnt These mobile ART services helped expand services to rural health facilities where resources are limited, bringing them as close as possible to where clients live. PMID:20931065

    Spasticity is a motor disorder frequently present in individuals with cerebral palsy (CP). This study aimed to evaluate the effect of low-level laser therapy (LLLT) on the spasticity of the masseter and anterior temporal muscle fibers in children with CP over three weeks of intermittent laser exposures. The bite force (BF) of the masticatory muscles and the amplitude of mouth opening were evaluated before and after laser irradiation in 30 children with CP. Both sides of the masseter and temporalis muscles were irradiated with low-intensity diode laser pulses of 808-nm wavelength six times over three consecutive weeks. During the subsequent three weeks of postlaser exposures, although no laser treatment was applied, the evaluation parameters were measured and recorded. A significant improvement in the amplitude of mouth opening and a decrease in the BF were observed in the weeks following LLLT (Plow-level energy exposures from a 808-nm diode laser to be an effective short-term therapeutic tool. This method increased the amplitude of mouth opening and decreased the muscle tonus of children with spastic CP over a time course of three weeks of intermittent laser applications.

    The relationship between obesity and prostate cancer (CaP) treatment failure is complex and may vary by patient- and neighborhood-level educational attainment. We evaluated whether patient- and neighborhood-level education is associated with the effect of obesity on biochemical recurrence. Seven hundred and forty-six CaP cases were classified into four groups: Concordant Low-Low: less educated cases (obesity and biochemical (PSA) failure after prostatectomy stratified by the concordant/discordant groups. The association of obesity with biochemical failure varied significantly by educational concordance/discordance (p = 0.007). Obesity was associated with risk of biochemical failure for less educated cases residing in less educated neighborhoods (HR 3.72, 95% CI 1.30-10.65). The relationship was not significant for other concordant/discordant groups. Obesity effects on CaP outcomes vary by multilevel educational discordance/concordance. Strategies to decrease prostate cancer risk of progression may focus on reduction in obesity, particularly for less educated cases residing in less educated neighborhoods.

    The full scale, room temperature Hanford Tank Waste Treatment and Immobilization Plant (WTP) High-Level Waste (HLW) melter riser test system was successfully operated with silicone oil and magnetite particles at a loading of 0.1 vol %. Design and construction of the system and instrumentation, and the selection and preparation of simulant materials, are briefly reviewed. Three experiments were completed. A prototypic pour rate was maintained, based on the volumetric flow rate. Settling and accumulation of magnetite particles were observed at the bottom of the riser and along the bottom of the throat after each experiment. The height of the accumulated layer at the bottom of the riser, after the first pouring experiment, approximated the expected level given the solids loading of 0.1 vol %. More detailed observations of particle resuspension and settling were made during and after the third pouring experiment. The accumulated layer of particles at the bottom of the riser appeared to be unaffected after a pouring cycle of approximately 15 minutes at the prototypic flow rate. The accumulated layer of particles along the bottom of the throat was somewhat reduced after the same pouring cycle. Review of the time-lapse recording showed that some of the settling particles flow from the riser into the throat. This may result in a thicker than expected settled layer in the throat.

    Full Text Available The qualitative characteristics of accounting information presented by financial-accounting reports represent a concept which was subsequently introduced in the national legal accounting framework and, as a rule, the national conceptual frameworks represent the documents by means of which these quality criteria are established. At a worldwide level, there are more international or national organisms that have an important role in the elaboration of accounting standards in general and more specifically in the formulation of qualitative characteristics of financial reporting. We find two important ones among them, and these are: International Accounting Standards Board, which creates and promotes International Financial Reporting Standards (IFRS, and Financial Accounting Standards Board, which elaborates Generally Accepted Accounting Principles (US GAAP. However, at the level of each country a standardizing authority decides the rules for producing the financial reports and the qualitative characteristics that must be respected by the information contained in these documents. In this context, this paper aims to present a few general considerations concerning the treatment of the qualitative characteristics of the financial-accounting information in different accounting systems, such as the American one, or the British, French, German, Romanian ones, with insistence on the international approach to qualitative characteristics.

    Community-level socioeconomic status, particularly insurance status, is increasingly becoming important as a possible determinant in patient outcomes. To determine the association of insurance and community-level socioeconomic status with outcome for patients with pharyngeal squamous cell carcinoma (SCC). This study extracted data from more than 1500 Commission on Cancer-accredited facilities collected in the National Cancer Database. A total of 35 559 patients diagnosed with SCC of the pharynx from 2004 through 2013 were identified. The χ2 test, Kaplan-Meier method, and Cox regression models were used to analyze data from April 1, 2016, through April 16, 2017. Overall survival was defined as time to death from the date of diagnosis. Among the 35 559 patients identified (75.6% men and 24.4% women; median age, 61 years [range, 18-90 years]), 15 146 (42.6%) had Medicare coverage; 13 061 (36.7%), private insurance; 4881 (13.7%), Medicaid coverage; and 2471 (6.9%), no insurance. Uninsured patients and Medicaid recipients were more likely to be younger, black, or Hispanic; to have lower median household income and lower educational attainment; to present with higher TNM stages of disease; and to start primary treatment at a later time from diagnosis. Those with private insurance (reference group) had significantly better overall survival than uninsured patients (hazard ratio [HR], 1.72; 95% CI, 1.59-1.87), Medicaid recipients (HR, 1.99; 95% CI, 1.88-2.12), or Medicare recipients (HR, 2.07; 95% CI, 1.99-2.16), as did those with median household income of at least $63 000 (reference) vs $48 000 to $62 999 (HR, 1.19; 95% CI, 1.13-1.26), $38 000 to $47 999 (HR, 1.31; 95% CI, 1.24-1.38), and less than $38 000 (HR, 1.51; 95% CI, 1.43-1.59). On multivariable analysis, insurance status and median household income remained independent prognostic factors for overall survival even after accounting for educational attainment, race, Charlson/Deyo comorbidity

    To describe the clinical results and the degree of satisfaction of patients submitted to thoracic sympathectomy at the level of the fourth and fifth ribs (R4-R5) for the treatment of axillary hyperhidrosis. We included 118 patients diagnosed with axillary hyperhidrosis and having undergone axillary sympathectomy at the R4-R5 level between March of 2003 and December of 2007 at the Paraná Federal University Hospital de Clínicas, located in the city of Curitiba, Brazil. All procedures were carried out by the same surgeon. Data regarding the resolution of axillary hyperhidrosis and the degree of patient satisfaction with the surgical outcome, as well as compensatory hyperhidrosis in the early and late postoperative periods (after 7 days and after 12 months, respectively), were collected. Of the 118 patients evaluated, 99 (83.9%) and 81 (68.6%) showed complete resolution of the symptoms in the early and late postoperative periods, respectively. Compensatory hyperhidrosis occurred in 49 patients (41.5%) in the early postoperative period and in 77 (65.2%) in the late postoperative period. Of those 77, 55 (71.4%) categorized the compensatory hyperhidrosis as mild. In the early postoperative period, 110 patients (93.2%) were satisfied with the surgical results, and 104 (88.1%) remained so in the late postoperative period. Sympathectomy at the R4-R5 level is efficient in the resolution of primary axillary hyperhidrosis. The degree of patient satisfaction with the long-term surgical results is high. Mild compensatory hyperhidrosis is the main side effect associated with this technique.

    Clematis terniflora DC. has potential pharmaceutical value; on the contrary, high-level UV-B irradiation with dark treatment led to the accumulation of secondary metabolites. Metabolomic and proteomic analyses of leaf of C. terniflora were performed to investigate the systematic response mechanisms to high-level UV-B irradiation with dark treatment. Metabolites related to carbohydrates, fatty acids, and amino acids and/or proteins related to stress, cell wall, and amino acid metabolism were gradually increased in response to high-level UV-B irradiation with dark treatment. On the basis of cluster analysis and mapping of proteins related to amino acid metabolism, the abundances of S-adenosylmethionine synthetase and cysteine synthase as well as 1,1-diphenyl-2-picrylhydrazyl scavenging activity were gradually increased in response to high-level UV-B irradiation with dark treatment. Furthermore, the abundance of dihydrolipoyl dehydrogenase/glutamate dehydrogenase and the content of γ-aminobutyric acid were also increased following high-level UV-B irradiation with dark treatment. Taken together, these results suggest that high-level UV-B irradiation with dark treatment induces the activation of reactive oxygen species scavenging system and γ-aminobutyric acid shunt pathway in leaf of C. terniflora.

    Metformin was found to affect plasma levels of some pituitary hormones. This study was aimed at investigating whether metformin treatment has an impact on plasma prolactin levels in bromocriptine-treated patients with hyperprolactinaemia and impaired glucose tolerance. The study included 27 patients with hyperprolactinaemia, who had been treated for at least 6 months with bromocriptine. Based on prolactin levels, bromocriptine-treated patients were divided into two groups: patients with elevated (group A, n = 12) and patients with normal (group B, n = 15) prolactin levels. The control group included 16 age-, sex- and weight-matched hyperprolactinaemia-free individuals with impaired glucose tolerance (group C).The lipid profile, fasting plasma glucose levels, the homeostatic model assessment of insulin resistance ratio (HOMA-IR), glycated haemoglobin, as well as plasma levels of prolactin, thyrotropin and insulin-like growth factor-1 (IGF-1) were assessed at baseline and after 4 months of metformin treatment (2.55-3 g daily). In all treatment groups, metformin reduced HOMA-IR, plasma triglycerides and 2-h postchallenge plasma glucose. In patients with hyperprolactinaemia, but not in the other groups of patients, metformin slightly reduced plasma levels of prolactin, and this effect correlated weakly with the metabolic effects of this drug. Our study shows that metformin decreases plasma prolactin levels only in patients with elevated levels of this hormone. The obtained results suggest that metformin treatment may bring some benefits to hyperprolactinaemic patients with coexisting glucose metabolism disturbances already receiving dopamine agonist therapy.

    Low-level laser therapy (LLLT) has been demonstrated to modulate inflammatory processes and immunological responses. The aim of this work was to investigate the hypothesis that near infrared LLLT (830 nm) over lymph nodes may reduce paw edema and contribute to the modulation of inflammation. The edema was induced by carrageenan inoculation (CGN) into the plantar surface of 100 male mice left hind paw. Animals were divided into five groups: CGN (control), no treatment; Diclo, sodium diclofenac; Paw, LLLT on the paw; Ly, LLLT on the inguinal lymph nodes; and Paw+Ly, LLLT in both paw and lymph nodes, and subdivided according to moment of irradiation: A-1 h and 2 h before CGN, B-1 h and immediately before CGN, C-1 and 2 h after CGN, and D-3.5 and 4.5 h after CGN. The parameters used were: energy=1 J, fluence=35 J/cm(2), power=100 mW during 10 s. Paw volume was measured before and 1 to 6 h after CGN, and myeloperoxidase (MPO) activity was analyzed. Edema prevention was obtained by the irradiation of Paw+Ly at moment A and at Ly at moment B, inhibition of edema formation was achieved by either Paw or Ly at moment C, and edema treatment was obtained by Paw or Ly at moment D (p<0.05). MPO activity was significantly reduced on Paw at moment A, Paw and Ly on C, and in all irradiated groups on B and D. Our results suggest that LLLT was able to produce both anti-inflammatory and pro-inflammatory effects depending on to the site and moment of irradiation.

    Full Text Available Background. Decentralization of antiretroviral therapy (ART services is a key strategy to achieving universal access to treatment for people living with HIV/AIDS. Our objective was to assess clinical and laboratory outcomes within a decentralized program in Nigeria. Methods. Using a tiered hub-and-spoke model to decentralize services, a tertiary hospital scaled down services to 13 secondary-level hospitals using national and program guidelines. We obtained sociodemographic, clinical, and immunovirologic data on previously antiretroviral drug naïve patients aged ≥15 years that received HAART for at least 6 months and compared treatment outcomes between the prime and satellite sites. Results. Out of 7,747 patients, 3729 (48.1% were enrolled at the satellites while on HAART, prime site patients achieved better immune reconstitution based on CD4+ cell counts at 12 (P<0.001 and 24 weeks (P<0.001 with similar responses at 48 weeks (P=0.11 and higher rates of viral suppression (<400 c/mL at 12 (P<0.001 and 48 weeks (P=0.03, but similar responses at 24 weeks (P=0.21. Mortality was 2.3% versus 5.0% (P<0.001 at prime and satellite sites, while transfer rate was 8.7% versus 5.5% (P=0.001 at prime and satellites. Conclusion. ART decentralization is feasible in resource-limited settings, but efforts have to be intensified to maintain good quality of care.

    Full Text Available At present, very little is known about the fate and perseverance of multiresistant bacteria and their resistance genes in natural aquatic environments. Treated, but partly also untreated sewage of the city of Lausanne, Switzerland is discharged into Vidy bay (Lake Geneva resulting in high levels of contamination in this part of the lake. In the present work we have studied the prevalence of multiresistant bacteria and resistance genes in the wastewater stream of Lausanne. Samples from hospital and municipal raw sewage, treated effluent from Lausanne’s wastewater treatment plant (WTP as well as lake water and sediment samples obtained close to the WTP outlet pipe and a remote site close to a drinking water pump were evaluated for the prevalence of multiresistant bacteria. Selected isolates were identified (16S rRNA gene fragment sequencing and characterized with regards to further resistances, resistance genes, and plasmids. Mostly, studies investigating this issue have relied on cultivation-based approaches. However, the limitations of these tools are well known, in particular for environmental microbial communities, and cultivation-independent molecular tools should be applied in parallel in order to take non-culturable organisms into account. Here we directly quantified the sulfonamide resistance genes sul1 and sul2 from environmental DNA extracts using TaqMan real-time quantitative PCR. Hospital sewage contained the highest load of multiresistant bacteria and antibiotic resistance genes. Wastewater treatment reduced the total bacterial load but evidence for selection of extremely multiresistant strains and accumulation of resistance genes was observed. Our data clearly indicated pollution of sediments with antibiotic resistance genes in the vicinity of the WTP outlet. The potential of lakes as reservoirs of multiresistant bacteria and potential risks are discussed.

    Full Text Available Introduction: Critical thinking is rational and sound thinking that involves investigation and review of opinions followed by actions and decision-making based on reasons with accurate and rational results. In our modern, complex world, we encounter multiple changes and competition in society, especially when it comes to using the latest technology; society must progress in this trend. Medical science is not exempt in this regard, considering that critical thinking is necessary in fulfilling its goals. This research aims to investigate the physicians’ critical thinking and patient satisfaction level in the Tabriz Sina Treatment and Educational Center.Methods: This study is both descriptive and analytical, and the statistical population involves all physicians and the patients of the Tabriz Sina Treatment and Educational Center in 2013. About 30 physicians and 170 patients were selected randomly, and data were collected using the Watson and Glaser critical thinking questionnaire, as well as the Mogimi and Ramazan patient satisfaction questionnaire. The data were then analyzed by Pearson correlation and regression analysis. Results: The results showed that there was a significant and positive relationship between critical thinking and patient satisfaction in all dimensions except identification. Changes in critical thinking dimensions also changed patient satisfaction. The regression test showed that the critical thinking independent variable effect on the dependent variable was 0.558, which indicated a relatively strong correlation between these variables.Conclusion: Although the critical thinking of the physicians and medical staff is important in patient satisfaction, there is no progress towards these goals in the health system. Healthcare authorities should try to empower critical thinking in order to achieve organizational goals.

    Full Text Available Introduction. Combined use of bevacizumab and conventional anticancer drugs leads to a significant improvement of treatment response in patients with metastatic colorectal carcinoma (CRC. Conventional treatment protocols exert undesired effects on the liver tissue. Hepatotoxic effects are manifested as a disturbance of liver function test parameters. The relation between clinical outcome and disorder of biochemical parameters has not been completely evaluated. Objective. The objective of our study was to examine whether clinical outcome in patients with liver metastatic CRC correlates with the level of liver function test parameters. Methods. The study included 96 patients with untreated liver metastatic CRC who received FOLFOX4 protocol with or without bevacizumab. Biochemical liver parameters were performed before and after the treatment completion. Treatment response was evaluated as disease regression, stable disease, and disease progression. The patients were divided into three groups according to the accomplished treatment response. Results. In the group of patients with disease regression the post-treatment levels of aspartate aminotransferase, alanine aminotransferase, and bilirubin were statistically significantly increased. In contrast to this, gamma-glutamyltransferase and protein post-treatment values were significantly lower in relation to initial values. In patients with stable disease, difference was found only in the level of proteins being lower after the treatment. In patients with disease progression, values of aspartate aminotransferase and bilirubin were significantly increased after completed treatment. Conclusion. Treatment responses are not completely associated with the level of liver function test parameters. The only parameter which correlated with treatment response is gamma-glutamyltransferase. Its decrease is accompanied with disease regression.

    The gut microbiome plays a key role in human health. This community is dynamic during the first three years of life, before stabilizing to an adult-like state. However, relatively little is known about the impact of environmental factors on the developing human gut microbiome. Here we report a longitudinal study of the gut microbiome based on DNA sequence analysis of monthly stool samples and clinical information from 39 children, approximately half of whom received multiple courses of antibiotics during the first three years of life. While the gut microbiome of most vaginally born children was dominated by Bacteroides species, we found that all four children born by Cesarean section and approximately 20% of vaginally born children lacked Bacteroides in the first six to eighteen months. Our longitudinal sampling, coupled with whole-genome shotgun sequencing, allowed us to detect strain-level variation as well as the abundance of antibiotic resistance (AR) genes. The microbiota of antibiotic-treated children was less diverse at the level of both species and strains, with some species often dominated by single strains. In addition, we observed short-term composition changes between consecutive samples from children treated with antibiotics. AR genes carried on microbial chromosomes showed a strong peak in abundance after antibiotic treatment followed by a sharp decline, whereas some genes on mobile elements persisted longer after the end of antibiotic therapy. Our results highlight the value of dense longitudinal studies with high-resolution strain profiles in studying the establishment and response to perturbation of the infant gut microbiome.

    Pulp and paper mills are well known for their sharp, sulphurous stack emissions, but the secondary treatment units also can be significant contributors to local odour. This study investigated the source(s) of earthy/musty emissions from a mixed hardwood pulp mill in response to a high local odour. Samples from five sites in the mill over five months were analyzed for earthy/musty volatile organic compounds (VOCs), examined microscopically, and plated for bacteria and moulds. In all cases, activated sludge showed substantial geosmin levels and to a lesser extent 2-methylisoborneol (MIB) at 2000-9000 times their odour threshold concentrations (OTCs). These VOCs were lower or absent upstream and downstream, suggesting that they were produced within the bioreactor. Geosmin and MIB were highest in late summer and declined over winter, and correlated with different operating parameters. Geosmin was most closely coupled with temperature and MIB with nitrogen uptake. Cyanobacteria were present in all sludge samples, but actinomycetes were not found. Gram-negative bacteria and one fungal species isolated from the bioreactor and secondary outfall tested negative for geosmin or MIB. We conclude: (i) geosmin and MIB contribute significantly to airborne odours from this mill, but are diluted below OTC levels at the river; (ii) these VOCs are generated by biota in the activated sludge; and (iii) cyanobacteria are likely primary source(s). The growth of cyanobacteria in activated sludge represents a loss of energy to the heterotrophic population; thus earthy/musty odours may represent a diagnostic for less than optimal conditions.

    We aimed to explore whether the use of methylphenidate relates leptin, ghrelin, adiponectin, and brain-derived neurotrophic factor (BDNF). In addition, the relationship between methylphenidate-related weight loss in attention deficit hyperactivity disorder (ADHD) patients and these biomolecules were evaluated. Thirty ADHD patients receiving methylphenidate and 20 healthy controls were included. Leptin, ghrelin, adiponectin, and BDNF levels were measured at baseline and after two-month treatment in both groups. At baseline, leptin, ghrelin, adiponectin, and BDNF levels were similar in the ADHD and control groups. The most common adverse events occurring in the ADHD group after a 2-month treatment period included loss of appetite (70%) and weight loss (66.7%). A significant difference was found in body weight, BMI, and CGI scores of the ADHD patients after the treatment. While post-treatment ghrelin and adiponectin levels were significantly higher in the ADHD group, BDNF level was significantly lower. Post-treatment decrease in leptin levels was not significant. Leptin and BDNF were not associated with poor appetite and/or weight loss due to methylphenidate treatment. However, ghrelin and adiponectin might be biomolecules that play a role in underlying neurobiological mechanisms of methylphenidate-related appetite or weight loss.

    This study evaluated the clinical efficacy of mirtazapine and its effect on serum brain-derived neurotrophic factor (BDNF) and tumor necrosis factor-α (TNF-α) levels in patients of major-depressive disorder (MDD) with severe depression. Patients (aged 18-60) with MDD diagnosed by DSM-IV criteria, and Hamilton Rating Scale for Depression (HAM-D) score ≥25 were included (n = 30). Mirtazapine was given in the doses of 30 mg/day. All patients were followed up for 12 weeks for the evaluation of clinical efficacy, safety along with serum BDNF and TNF-α levels. HAM-D score at the start of treatment was 30.1 ± 1.92, which significantly (p treatment. In responders, mean serum BDNF levels at the start of treatment were 2.32 ± 0.3 ng/ml, which significantly (p treatment and mean serum TNF-α levels at the start were 5.18 ± 0.67 pg/ml, which significantly decreased to 4.36 ± 0.72 pg/ml (p treatment. Our results suggest that mirtazapine is effective and well tolerated in severely depressed patients and treatment response is associated with an increase in serum BDNF and a decrease in serum TNF-α levels. © 2016 S.

    Full Text Available Compound Danshen Formula (CDF is a widely used Traditional Chinese Medicine (TCM which has been extensively applied in clinical treatment of cardiovascular diseases (CVDs. However, the underlying mechanism of clinical administrating CDF on CVDs is not clear. In this study, the pharmacological effect of CDF on CVDs was analyzed at a systemic point of view. A systems-pharmacological model based on chemical, chemogenomics and pharmacological data is developed via network reconstruction approach. By using this model, we performed a high-throughput in silico screen and obtained a group of compounds from CDF which possess desirable pharmacodynamical and pharmacological characteristics. These compounds and the corresponding protein targets are further used to search against biological databases, such as the compound-target associations, compound-pathway connections and disease-target interactions for reconstructing the biologically meaningful networks for a TCM formula. This study not only made a contribution to a better understanding of the mechanisms of CDF, but also proposed a strategy to develop novel TCM candidates at a network pharmacology level.

    In recent years, there has been an upsurge in the application of low-level laser therapy in various medical diseases. Additionally, vibration therapy is a new and effective measure to prevent muscular atrophy and osteoporosis, along with some general health-related beneficial effects of exercise on skeletal muscles such as improvement of endothelial function and an increased enzyme capacity of energy metabolism. The aim of this study was to evaluate the application of a 635 nm and 0.040 W exit power per multiple diode laser in combination with vibration therapy for the application of non-invasive reduction of circumference in patients with localized adiposity and cellulite. The study enrolled men and women (N = 33) aged 18-64 years with localized adiposity or fibrous cellulite. The evaluation parameters were: photographic evaluation, perimetric evaluation, blood tests, ecographic evaluation, histological evaluation, and subjective and objective tests. The results produced were statistically analyzed and resulted in a significant reduction of fat thickness when compared to the measurement prior to the treatment (P cellulite.

    The distribution and fate of polybrominated diphenyl ethers (PBDEs) in a riparian ecosystem nearby a wastewater treatment plant effluent were investigated. Different aqueous and terrestrial samples such as soil, sediment, plants, and invertebrates were collected and analyzed for tri- to heptabrominated PBDEs. Furthermore, the food web structure was elucidated using stable carbon and nitrogen isotopes. The highest PBDE levels were found for sediment- and soil-dwelling invertebrates, such as earthworms (Σ13 PBDEs 144 ng/g lipid weight), Tubifex tubifex (77 ng/g lw), and scarab larvae (49 ng/g lw). Differences in congener composition profiles among the different matrices show that the environmental distribution and fate of PBDEs in ecosystems can be very complex. Among the analyzed PBDEs in this ecosystem, the tetra-brominated BDE-47 was the dominant PBDE congener and followed by the penta-brominated BDE-99. A potential trend of increasing BDE-47/99 ratio with the increase of δ(15)N was observed for species with similar energy sources (δ(13)C), indicating a higher bioaccumulation potential for BDE-47 in this ecosystem. A significant correlation was also found between PBDEs and polychlorinated biphenyls (PCBs), indicating similar sources and fate between the two compound groups in this area. The biota-soil or biota-sediment accumulation factors (BSAFs) were somewhat different among the PBDE congeners and species, but were generally highest for those with log Kow values around 6.5-7.

    A group of 9 Mexican lepromatous leprosy patients was studied at the beginning of a type II reaction (erythema nodosum leprosum, ENL) and after 1 or 2 months of thalidomide treatment. ENL patients at the onset of the reaction had slightly higher amounts of anti-Mycobacterium leprae IgG1 and IgG2 antibodies, compared to similar lepromatous patients that did not develop ENL. Neither these antibody levels nor IgM and the other IgG subclasses were importantly modified after thalidomide treatment. Serum TNF was significantly higher in the patients that developed ENL compared to those that did not develop the reaction. TNF levels were slightly decreased after 1 month of thalidomide treatment and significantly decreased after 2 months of treatment. Serum IFN-gamma was significantly lower in patients at the onset of ENL and was increased after 1 and 2 months of thalidomide treatment.

    Treatment efficacy studies typically use pre-treatment sea lice abundance as the baseline. However, the pre-treatment counting window often varies from the day of treatment to several days before treatment. We assessed the effect of lead time on baseline estimates, using historical data (2010-14) from a sea lice data management programme (Fish-iTrends). Data were aggregated at the cage level for three life stages: (i) chalimus, (ii) pre-adult and adult male and (iii) adult female. Sea lice counts were log-transformed, and mean counts by lead time relative to treatment day were computed and compared separately for each life stage, using linear mixed models. There were 1,658 observations (treatment events) from 56 sites in 5 Bay Management Areas. Our study showed that lead time had a significant effect on the estimated sea lice abundance, which was moderated by season. During the late summer and autumn periods, counting on the day of treatment gave significantly higher values than other days and would be a more appropriate baseline estimate, while during spring and early summer abundance estimates were comparable among counts within 5 days of treatment. A season-based lead time window may be most appropriate when estimating baseline sea lice levels.

    Highlights: •Most cancer types of the NCI60 have sub-sets of cell lines with high GHR expression. •GHR is highly expressed in melanoma cell lines. •GHR is elevated in advanced stage IV metastatic tumors vs. stage III. •GH treatment of metastatic melanoma cell lines alters growth and cell signaling. -- Abstract: Accumulating evidence implicates the growth hormone receptor (GHR) in carcinogenesis. While multiple studies show evidence for expression of growth hormone (GH) and GHR mRNA in human cancer tissue, there is a lack of quantification and only a few cancer types have been investigated. The National Cancer Institute’s NCI60 panel includes 60 cancer cell lines from nine types of human cancer: breast, CNS, colon, leukemia, melanoma, non-small cell lung, ovarian, prostate and renal. We utilized this panel to quantify expression of GHR, GH, prolactin receptor (PRLR) and prolactin (PRL) mRNA with real-time RT qPCR. Both GHR and PRLR show a broad range of expression within and among most cancer types. Strikingly, GHR expression is nearly 50-fold higher in melanoma than in the panel as a whole. Analysis of human metastatic melanoma biopsies confirmed GHR gene expression in melanoma tissue. In these human biopsies, the level of GHR mRNA is elevated in advanced stage IV tumor samples compared to stage III. Due to the novel finding of high GHR in melanoma, we examined the effect of GH treatment on three NCI60 melanoma lines (MDA-MB-435, UACC-62 and SK-MEL-5). GH increased proliferation in two out of three cell lines tested. Further analysis revealed GH-induced activation of STAT5 and mTOR in a cell line dependent manner. In conclusion, we have identified cell lines and cancer types that are ideal to study the role of GH and PRL in cancer, yet have been largely overlooked. Furthermore, we found that human metastatic melanoma tumors express GHR and cell lines possess active GHRs that can modulate multiple signaling pathways and alter cell proliferation. Based on

    Full Text Available Background & objectives: National Anti-retroviral treatment (ART programme in India was launched in 2004. Since then, there has been no published country representative estimate of suboptimal adherence among people living with HIV (PLHIV on first line ART in public settings. Hence a multicentric study was undertaken in 15 States of India to assess the level of suboptimal adherence and its determinants among PLHIV. Methods: Using a prospective observational study design, 3285 PLHIV were enrolled and followed up to six months across 30 ART centres in India. Adherence was assessed using pill count and self-reported recall method and determinants of suboptimal adherence were explored based on the responses to various issues as perceived by them. Results: Suboptimal adherence was found in 24.5 per cent PLHIV. Determinants of suboptimal adherence were illiteracy (OR-1.341, CI-1.080-1.665 , on ART for less than 6 months (OR-1.540, CI- 1.280-1.853, male gender (OR for females -0.807, CI- 0.662-0.982, tribals (OR-2.246, CI-1.134-4.447, on efavirenz (EFA regimen (OR- 1.479, CI - 1.190 - 1.837, presence of anxiety (OR- 1.375, CI - 1.117 - 1.692, non-disclosure of HIV status to family (OR- 1.549, CI - 1.176 - 2.039, not motivated for treatment (OR- 1.389, CI - 1.093 - 1.756, neglect from friends (OR-1.368, CI-1.069-1.751, frequent change of residence (OR- 3.373, CI - 2.659 - 4.278, travel expenses (OR- 1.364, CI - 1.138-1.649, not meeting the PLHIV volunteer/community care coordinator at the ART center (OR-1.639, CI-1.330-2.019. Interpretation & conclusions: To enhance identification of PLHIV vulnerable to suboptimal adherence, the existing checklist to identify the barriers to adherence in the National ART Guidelines needs to be updated based on the study findings. Quality of comprehensive adherence support services needs to be improved coupled with vigilant monitoring of adherence measurement.

    2016-05-01

    Previous studies have shown that virtual walking to treat spinal cord injury-related neuropathic pain (SCI-NP) can be beneficial, although the type of SCI-NP that may benefit the most is unclear. This study's aims were to (1) determine the effect of location of SCI-NP on pain outcomes after virtual walking treatment and (2) examine the potential relationship between neuronal hyperexcitability, as measured by quantitative sensory testing, and pain reduction after virtual walking treatment. Participants were recruited from a larger ongoing trial examining the benefits of virtual walking in SCI-NP. Neuropathic pain was classified according to location of pain (at- or below-level). In addition, quantitative sensory testing was performed on a subset of individuals at a nonpainful area corresponding to the level of their injury before virtual walking treatment and was used to characterize treatment response. These pilot results suggest that when considered as a group, SCI-NP was responsive to treatment irrespective of the location of pain (F1, 44 = 4.82, P = 0.03), with a trend for the greatest reduction occurring in at-level SCI-NP (F1, 44 = 3.18, P = 0.08). These pilot results also potentially implicate cold, innocuous cool, and pressure hypersensitivity at the level of injury in attenuating the benefits of virtual walking to below-level pain, suggesting certain SCI-NP sensory profiles may be less responsive to virtual walking.

    Sphingolipids are bioactive molecules with a putative role in inflammation. Alterations in sphingolipids, in particular ceramides, have been consistently observed in psoriatic skin. Herein, we quantified the circulating sphingolipid profile in individuals with mild or severe psoriasis as well as healthy controls. In addition, the effects of anti-TNF-α treatment were determined. Levels of sphingoid bases, including sphingosine-1-phosphate (S1P), increased in severe (P psoriasis relative to healthy controls (n = 32). These alterations were not reversed in severe patients (n = 16) after anti-TNF-α treatment despite significant improvement in psoriasis lesions. Circulating levels of sphingomyelins and ceramides shifted in a fatty acid chain length-dependent manner. These alterations were also observed in psoriasis skin lesions and were associated with changes in mRNA levels of ceramide synthases. The lack of S1P response to treatment may have pathobiological implications due to its close relation to the vascular and immune systems. In particular, increased levels of sphingolipids and especially S1P in severe psoriasis patients requiring biological treatment may potentially be associated with cardiovascular comorbidities. The fact that shifts in S1P levels were not ameliorated by anti-TNF-α treatment, despite improvements in the skin lesions, further supports targeting S1P receptors as therapy for severe psoriasis.

    Highly dense and c-axis oriented zinc oxide (ZnO) nanorods with hexagonal wurtzite facets were deposited on fluorine doped tin oxide coated glass substrates by a simple and cost-effective electrodeposition method at low bath temperature (80 °C). The as-grown samples were then annealed at various temperatures (T{sub A} = 100–500 °C) in different environments (e.g., zinc, oxygen, air, and vacuum) to understand their photoluminescence (PL) behavior in the ultra-violet (UV) and the visible regions. The PL results revealed that the as-deposited ZnO nanorods consisted of oxygen vacancy (V{sub O}), zinc interstitial (Zn{sub i}), and oxygen interstitial (O{sub i}) defects and these can be reduced significantly by annealing in different environments at optimal annealing temperatures. However, the intensity of deep level emission increased for T{sub A} greater than the optimized values for the respective environments due to the introduction of various defect centers. For example, for T{sub A} ≥ 450 °C in the oxygen and air environments, the density of O{sub i} defects increased, whereas, the green emission associated with V{sub O} is dominant in the vacuum annealed (T{sub A} = 500 °C) ZnO nanorods. The UV peak red shifted after the post-growth annealing treatments in all the environments and the vacuum annealed sample exhibited highest UV peak intensity. The observations from the PL data are supported by the micro-Raman spectroscopy. The present study gives new insight into the origin of different defects that exist in the electrodeposited ZnO nanorods and how these defects can be precisely controlled in order to get the desired emissions for the opto-electronic applications.

  10. Systems biology investigation of cAMP modulation to increase SMN levels for the treatment of spinal muscular atrophy.

    Directory of Open Access Journals (Sweden)

    Sean G Mack

    Full Text Available Spinal muscular atrophy (SMA, a leading genetic cause of infant death worldwide, is an autosomal recessive disorder caused by the loss of SMN1 (survival motor neuron 1, which encodes the protein SMN. The loss of SMN1 causes a deficiency in SMN protein levels leading to motor neuron cell death in the anterior horn of the spinal cord. SMN2, however, can also produce some functional SMN to partially compensate for loss of SMN1 in SMA suggesting increasing transcription of SMN2 as a potential therapy to treat patients with SMA. A cAMP response element was identified on the SMN2 promoter, implicating cAMP activation as a step in the transcription of SMN2. Therefore, we investigated the effects of modulating the cAMP signaling cascade on SMN production in vitro and in silico. SMA patient fibroblasts were treated with the cAMP signaling modulators rolipram, salbutamol, dbcAMP, epinephrine and forskolin. All of the modulators tested were able to increase gem formation, a marker for SMN protein in the nucleus, in a dose-dependent manner. We then derived two possible mathematical models simulating the regulation of SMN2 expression by cAMP signaling. Both models fit well with our experimental data. In silico treatment of SMA fibroblasts simultaneously with two different cAMP modulators resulted in an additive increase in gem formation. This study shows how a systems biology approach can be used to develop potential therapeutic targets for treating SMA.

    Five experiments were completed with the full-scale, room temperature Hanford Waste Treatment and Immobilization Plant (WTP) high-level waste (HLW) melter riser test system to observe particle flow and settling in support of a crystal tolerant approach to melter operation. A prototypic pour rate was maintained based on the volumetric flow rate. Accumulation of particles was observed at the bottom of the riser and along the bottom of the throat after each experiment. Measurements of the accumulated layer thicknesses showed that the settled particles at the bottom of the riser did not vary in thickness during pouring cycles or idle periods. Some of the settled particles at the bottom of the throat were re-suspended during subsequent pouring cycles, and settled back to approximately the same thickness after each idle period. The cause of the consistency of the accumulated layer thicknesses is not year clear, but was hypothesized to be related to particle flow back to the feed tank. Additional experiments reinforced the observation of particle flow along a considerable portion of the throat during idle periods. Limitations of the system are noted in this report and may be addressed via future modifications. Follow-on experiments will be designed to evaluate the impact of pouring rate on particle re-suspension, the influence of feed tank agitation on particle accumulation, and the effect of changes in air lance positioning on the accumulation and re-suspension of particles at the bottom of the riser. A method for sampling the accumulated particles will be developed to support particle size distribution analyses. Thicker accumulated layers will be intentionally formed via direct addition of particles to select areas of the system to better understand the ability to continue pouring and re-suspend particles. Results from the room temperature system will be correlated with observations and data from the Research Scale Melter (RSM) at Pacific Northwest National Laboratory

    The fate of cyclic and linear volatile methylsiloxanes (VMSs) was evaluated in a wastewater treatment plant (WWTP) using constant water level sequencing batch reactors from Dalian, China. Influent, effluent, and sewage sludge samples were collected for seven consecutive days. The mean concentrations of cyclic VMSs (cVMSs) in influent and effluent samples are 1.05 μg L{sup −1} and 0.343 μg L{sup −1}; the total removal efficiency of VMSs is > 60%. Linear VMS (lVMS) concentration is under the quantification limitation in aquatic samples but is found in sludge samples with a value of 90 μg kg{sup −1}. High solid-water partition coefficients result in high VMS concentrations in sludge with the mean value of 5030 μg kg{sup −1}. No significant differences of the daily mass flows are found when comparing the concentration during the weekend and during working days. The estimated mass load of total cVMSs is 194 mg d{sup −1} 1000 inhabitants{sup −1} derived for the population. A mass balance model of the WWTP was developed and derived to simulate the fate of cVMSs. The removal by sorption on sludge increases, and the volatilization decreases with increasing hydrophobicity and decreasing volatility for cVMSs. Sensitivity analysis shows that the total suspended solid concentration in the effluent, mixed liquor suspended solid concentration, the sewage sludge flow rate, and the influent flow rate are the most influential parameters on the mass distribution of cVMSs in this WWTP. - Highlights: • A mass balance model for siloxanes was developed in sequencing batch reactor. • Total suspended solid in effluent has the most influence on removal efficiency. • Enhancement of suspended solid removal reduces the release to aquatic environment.

    The governments of Norway and the US have committed their mutual cooperation and support the Murmansk Shipping Company (MSCo) to expand and upgrade the Low-Level Liquid Radioactive Waste (LLRW) treatment system located at the facilities of the Russian company RTP Atomflot, in Murmansk, Russia. RTP Atomflot provides support services to the Russian icebreaker fleet operated by the MSCo. The objective is to enable Russia to permanently cease disposing of this waste in Arctic waters. The proposed modifications will increase the facility`s capacity from 1,200 m{sup 3} per year to 5,000 m{sup 3} per year, will permit the facility to process high-salt wastes from the Russian Navy`s Northern fleet, and will improve the stabilization and interim storage of the processed wastes. The three countries set up a cooperative review of the evolving design information, conducted by a joint US and Norwegian technical team from April through December, 1995. To ensure that US and Norwegian funds produce a final facility which will meet the objectives, this report documents the design as described by Atomflot and the Russian business organization, ASPECT, both in design documents and orally. During the detailed review process, many questions were generated, and many design details developed which are outlined here. The design is based on the adsorption of radionuclides on selected inorganic resins, and desalination and concentration using electromembranes. The US/Norwegian technical team reviewed the available information and recommended that the construction commence; they also recommended that a monitoring program for facility performance be instituted.

    Objective: Through studying pneumonia infant's serum creatine kinase and troponin T level changes and combined with electrocardiogram analysis to discuss its meaning to pneumonia infant's clinical diagnosis and treatment. Method: 73 cases of pneumonia infants were selected as the study group in our hospital from January 2014 to June 2014, meanwhile 58 cases of healthy infants were selected as the control group, to proceed serum CK and CTnT and electrocardiogram examination of both groups. Results: Before treatment, ordinary pneumonia group's CK level raised (P>0.05),CK-MB and CTnT levels significantly raised (P0.05), ECG returned to normal; severe pneumonia group's CK level obviously returned to normal range (P>0.05), but CK-MB and CTnT levels still exist significant difference (P0.05), electrocardiogram also returned to normal, only sinus tachycardia and bundle branch block were difficult to return to normal. Conclusion: Serum CK, CK-MB and CTnT levels of pneumonia infants rise along with the aggravation of disease, and ECG level is abnormal, after treatment, most pneumonia infants are cured. This illustrates infant pneumonia could easily cause multiple organ system damage, especially myocardial injury, monitoring CK, CK-MB and CTnT levels, combined with electrocardiogram data has important reference value to the diagnosis of pneumonia.

    Full Text Available The aim of this study was to assess the change of IL-37 concentrations in rheumatoid arthritis (RA patients under Disease-modifying anti-rheumatic drug (DMARD therapy, and to establish a correlation between Interleukin-37 and pro-inflammatory cytokines in plasma and disease activity. The plasma level of IL-37 was determined using ELISA in 50 newly diagnosed RA patients and 30 healthy controls (HC. Plasma levels of IL-17A, IL-6 and TNF-α were measured using flow a cytometric bead array assay. We found that the concentrations of IL-37, as well as IL-17A, IL-6 and TNF-α, were higher in plasma of RA patients compared to HCs. Compared to patients who did not respond to DMARD treatment, treatment of patients responsive to DMARDs resulted in down-regulation of IL-17A, IL-6 and TNF-α expression. The plasma level of the anti-inflammatory cytokine IL-37 was also decreased in drug responders after DMARD treatment. The plasma level of IL-37 in RA patients was positively correlated with pro-inflammatory cytokines (IL-17A, TNF-α and disease activity (CRP, DAS28 in RA patients. IL-37 expression in RA and during DMARD treatment appears to be controlled by the level of pro-inflammatory cytokines. This results in a strong correlation between plasma levels of IL-37 and disease activity in RA patients.

    Full Text Available Allergy is often accompanied by infections and lower levels of antimicrobial peptides (AMPs. Vitamin D has been shown to increase expression of selected AMPs. In this study we investigated whether antimicrobial peptide levels in nasal secretions of allergic asthma patients are lower than in healthy controls, and whether administration of the active form of vitamin D (1,25(OH2D3 affects these antimicrobial peptide levels.The levels of antimicrobial peptides in nasal secretions were compared between 19 allergic asthma patients and 23 healthy controls. The effect of seven days daily oral treatment with 2 μg 1,25(OH2D3 on antimicrobial peptides in nasal secretions was assessed in a placebo-controlled cross-over clinical study.Levels of neutrophil α-defensins (human neutrophil peptides 1-3; HNP1-3 and lipocalin 2 (LCN2; also known as NGAL were significantly lower in asthmatics, but no differences in LL-37 and SLPI were detected. Treatment with a short-term 1,25(OH2D3 caused a small increase in HNP1-3, but not when the asthma and control groups were analyzed separately. LL-37, LCN2 and SLPI did not change after treatment with 1,25(OH2D3.Levels of the antimicrobial peptides HNP1-3 and LCN2 are lower in nasal secretions in asthmatics and are not substantially affected by a short-term treatment with active vitamin D.

    Interferon-γ-inducible protein 10 (IP-10), also known as chemokine C-X-C motif ligand (CXCL) 10, is closely associated with antiviral immunity and the progression of chronic hepatitis B (CHB). However, the value of baseline serological and histological IP-10 expression levels in predicting the efficacy of the antiviral response to nucleoside/nucleotide analogues (NAs) is still unknown. In our research, intrahepatic and peripheral IP-10 expression levels were systemically examined before and after treatment with entecavir (ETV). Baseline serological and histological IP-10 expression levels were significantly increased in patients with CHB, particularly in patients with higher degrees of liver inflammation and liver fibrosis. Moreover, higher baseline intrahepatic IP-10 levels indicated better prognoses in patients with CHB after entecavir therapy. The baseline IP-10 level was also positively associated with several clinical parameters, including baseline levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), hepatitis B virus (HBV) DNA, and hepatitis B surface antigen (HBsAg), and with the decrease in HBsAg levels after treatment. In addition, monocyte-derived IP-10 was expressed at higher levels in patients with CHB than in patients with liver cirrhosis (LC) and healthy controls (HC). According to the results of our in vitro experiments, IP-10 directly promoted hepatocyte apoptosis. Based on these findings, baseline serological and histological IP-10 levels might predict CHB severity and the decrease in HBsAg levels after entecavir therapy.

The patients were given intramuscular administration of cholecalciferol at a dose of 300,000 IU/month for 3 months. At the time of diagnoses and after the treatment of vitamin D, free T3 (FT3, free T4 (FT4, thyroid stimulating hormone (TSH, antithyroid peroxidase (anti-TPO, antithyroglobulin (anti-TG, 25 (OH D3, parathormone (PTH, calcium (Ca, phosphorus (P and alkaline phosphatase (ALP levels were measured in all patients; TNF-a, IL-6 and IL-1ß levels were measured in only 43 patients. Results: A statistically significant difference (p˂0.05 was observed between the pre and post treatment FT4, TSH, antiTPO, antiTG, PTH and ALP levels. After the treatment of vitamin D, a statistically significant increase was found in 25 (OH D3 and FT4 levels, and a significant decrease was found in TSH, antiTPO, antiTG, PTH and ALP levels, whereas no significant difference was noted in FT3, Ca, P, TNF- a, IL-6 and IL-1ß levels. Further, levels of vitamin D were not correlated with FT3, FT4, TSH, antiTPO, antiTG, TNF-a, IL-6 and IL-1ß levels (p˃0.05. Conclusions: For patients with both vitamin D deficiency and newly diagnosed HT, treatment of vitamin D had a positive effect on the thyroid antigenicity and thyroid function.

    Full Text Available Background and Objective: Hyperhomocysteinemia is a well-known risk factor for cardiovascular disease. Although metformin therapy can increase homocysteine (Hcy levels, it frequently is used as an oral medicine in women with polycystic ovary syndrome (PCOS, who might be at risk of catching diabetes mellitus. The aim of this study was to investigate the effect of metformin on the levels of serum Hcy, vitamin B12 (vit B12, and folic acid in patients with PCOS. Materials and Methods: An interventional study was designed with 18 patients with PCOS at the Fatemehzahra infertility Hospital in Babol, Iran. Metformin treatment (500 mg twice daily was initiated in all patients for a period of consecutive 6 months. The levels of serum Hcy, vit B12, and folic acid were measured in the participants before and after metformin treatment. Results: The mean vit B12 level showed a significant decrease in patients after 6 months of metformin treatment (P = 0.002. However, there was no significant difference in serum folic acid levels. The mean Hcy levels increased after treatment, but this difference not was statistically significant. When patients were stratified into four subgroups by their insulin sensitivity and body mass index (BMI, relatively similar results were obtained in the subgroups, except that Hcy levels in the overweight/obesity group (BMI > 25 kg/m2 after treatment showed a significant increase (P = 0.01. Conclusion: These findings indicate that metformin increases the serum Hcy concentration in patients with PCOS especially in the women with BMI > 25 kg/m2. The possible mechanism for this effect would be the obvious reduction in the levels of vit B12.

A recent study found that the level of brain-derived neurotrophic factor (BDNF increased after antidepressant treatment in remitted patients. This study evaluated serum BDNF levels in MDD patients with chronic maintenance treatment, and compared these between remission and nonremission groups.Materials and methods: Serum BDNF levels were measured in 34 MDD patients and 35 healthy controls. The severity of depression was measured using the Hamilton Depression Rating Scale (Ham-D. The MDD patients were divided into remission and nonremission groups according to a cutoff total Ham-D score of either ≤7 or ≤6.Results: Serum BDNF levels differed significantly between the remission, nonremission, and healthy control groups (P<0.05. The Bonferroni post hoc test confirmed that serum BDNF levels were significantly lower in the nonremission group than in the healthy-control group (P<0.05, but did not differ significantly between the remission and healthy-control groups.Limitations: This study included a small sample, and measured serum BDNF levels in the MDD patients at only one point during the maintenance treatment.Conclusion: This study found that serum BDNF levels during maintenance treatment were lower in MDD patients with failure to achieve remission than in controls, while the remitted subjects had normalized serum BDNF levels. A lower level of serum BDNF during maintenance treatment is associated with failure to achieve remission in patients with major depression. Moreover, serum BDNF levels

    Full Text Available BackgroundMost type 2 diabetes mellitus patients are obese and have obesity related vascular complications. Exenatide treatment is well known for both decreasing glycated hemoglobin levels and reduction in body weight. So, this study aimed to determine the effects of exenatide on body composition, glycated hemoglobin levels, and vascular stiffness in obese type 2 diabetes mellitus patients.MethodsFor 1 month, 32 obese type 2 diabetes mellitus patients were administered 5 µg of exenatide twice daily. The dosage was then increased to 10 µg. Patients' height, body weight, glycated hemoglobin levels, lipid profile, pulse wave velocity (PWV, body mass index, fat mass, and muscle mass were measured by using Inbody at baseline and after 3 months of treatment.ResultsAfter 3 months of treatment, glycated hemoglobin levels decreased significantly (P=0.007. Triglyceride, total cholesterol, and low density lipoprotein levels decreased, while aspartate aminotransferase and alanine aminotransferase levels were no change. Body weight, and fat mass decreased significantly (P=0.002 and P=0.001, respectively, while interestingly, muscle mass did not decrease (P=0.289. In addition to, Waist-to-hip ratio and aortic PWV decreased significantly (P=0.006 and P=0.001, respectively.ConclusionEffects of short term exenatide use in obese type 2 diabetes mellitus with cardiometabolic high risk patients not only reduced body weight without muscle mass loss, body fat mass, and glycated hemoglobin levels but also improved aortic PWV in accordance with waist to hip ratio.

    The aim of this study was to determine the correlation between dynamic changes in serum cytokine/chemokine expression levels in response to entecavir (ETV) treatment and HBV e antigen (HBeAg) seroconversion in patients with chronic hepatitis B (CHB). Four cytokines (interleukin [IL]-4, IL-6, IL-8, and interferon-γ) and five chemokines (macro-phage inflammatory protein [MIP]-1α, MIP-1β, platelet derived growth factor-BB, and interferon-inducible protein 10 [IP-10]) before ETV therapy and at 3, 6, 12, 24, 36 and 60 months during therapy in 105 CHB patients were analyzed. The results showed that the low decrease rate of IP-10 levels after 1 year of ETV treatment was an independent predictor of HBeAg seroconversion at year 5 (Hazard ratio = 0.972). The area under the receiver operating characteristic curves for the decrease rate of IP-10 levels after 1 year of treatment to discriminate a year-5 HBeAg seroconversion was 0.752 (p = 0.005). The results indicate that higher IP-10 level at year one of ETV treatment is associated with an increased probability of HBeAg seroconversion. Quantification of IP-10 during ETV treatment may help to predict long-term HBeAg seroconversion in patients with CHB.

    The objective of the study was to determine the stress levels of girls with central precocious puberty (CPP) before and during treatment with a long-acting gonadotropin-releasing hormone agonist (GnRHa). The Child Stress Scale (CSS) was used for 10 unrelated girls with CPP before and after the first year of GnRHa treatment. The CSS is divided into four subscales (physical, psychological, psychological with depressive component and psychophysiological reactions). Through a quantitative analysis, it is possible to classify stress into four stages: alarm, resistance, near-exhaustion and exhaustion. At diagnosis, 90% of the girls showed stress levels scores at the alarm or resistance stage on at least one subscale, mostly in terms of physical and psychological reactions. The mean total stress score was significantly higher before when compared to after GnRHa treatment (43.4±15.6 vs. 28.9±9.7; pstress scores obtained in all subscales, except the one on psychophysiological reactions, were significantly higher before GnRHa treatment. Higher stress levels were a common finding in girls with CPP before treatment. The significant stress level reduction after pubertal suppression reinforces the idea that sexual precocity is a stressful condition in children. The CSS might be a useful tool for psychological assessment of patients with CPP.

    Allopregnanolone plays a role in the stress response and homeostasis. Alterations in the estrogen milieu during the perinatal period influence brain development in a manner that persists into adulthood. Accordingly, we showed that a single administration of estradiol benzoate (EB) on the day of birth decreases brain allopregnanolone concentrations in adult female rats. We examined whether the persistent decrease in allopregnanolone concentrations, induced by neonatal EB treatment, might affect sensitivity to stress during adulthood. Female rats were treated with 10 μg of EB or vehicle on the day of birth. During adulthood, the response to acute foot shock stress was assessed by measuring changes in brain allopregnanolone and corticosterone levels, as well as extracellular dopamine output in the medial prefrontal cortex (mPFC). Neonatal EB treatment enhanced stress-stimulated allopregnanolone levels in the hypothalamus, as well as extracellular dopamine output in the mPFC; this latest effect is reverted by subchronic progesterone treatment. By contrast, neonatal EB treatment did not alter stress-induced corticosterone levels, sensitivity to hypothalamic-pituitary-adrenal (HPA) axis negative feedback, or abundance of glucocorticoid and mineralocorticoid receptors. The persistent decrease in brain allopregnanolone concentrations, induced by neonatal EB treatment, enhances stress-stimulated allopregnanolone levels and extracellular dopamine output during adulthood. These effects are not associated to an impairment in HPA axis activity. Heightened sensitivity to stress is a risk factor for several neuropsychiatric disorders; these results suggest that exposure to estrogen during development may predispose individuals to such disorders.

    Statement of the Problem: Recurrent aphthous stomatitis (RAS) is one of the most common lesions in the oral cavity. Due to its multifactorial nature, there is no definitive treatment for RAS. Laser therapy is one of the suggested treatments to reduce patient’s discomfort. Purpose: The purpose of the present clinical trial is to assess the effect of low and high level laser therapy on pain control and wound healing of RAS. Materials and Method: Thirty six patients with minor RAS were divided into three groups. Group 1 (n=14) received CO2 laser, group 2 (n=12) were treated with InGaAlP Diode laser and group 3 (n=10) received sham laser as placebo. All patients were evaluated daily up to 15 days after receiving one session of laser therapy. Pain severity before and after treatment, wound healing, patient’s satisfaction, and functional disturbance before and after treatment were recorded for each patient. Results: According to statistical analysis, pain reduction after treatment in group 1 was 7.00±2.41, in group 2 was 2.08±2.31, and in group 3 was 1.40±1.77. In addition, a significant difference was observed in the reduction of functional complications in CO2 laser treated patients compared to the other two groups. Conclusion: High-level laser treatment showed analgesic effects on RAS, but no healing was observed. Low-level laser therapy demonstrated no positive effect on recurrent aphthous ulcers.

    Ovarian cancer is the leading cause of death from gynaecological malignancy. Despite improved detection and treatment options, relapse rates remain high. Combining immunotherapy with the current standard treatments may provide an improved prognosis, however, little is known about how standard chemotherapy affects immune potential (particularly T cells) over time, and hence, when to optimally combine it with immunotherapy (e.g., vaccines). Herein, we assess the frequency and ratio of CD8+ central memory and effector T cells as well as CD4+ effector and regulatory T cells (Tregs) during the first 18 weeks of standard chemotherapy for ovarian cancer patients. In this pilot study, we observed increased levels of recently activated Tregs with tumor migrating ability (CD4+CD25{sup hi}Foxp3+CD127−CCR4+CD38+ cells) in patients when compared to controls. Although frequency changes of Tregs as well as the ratio of effector T cells to Tregs were observed during treatment, the Tregs consistently returned to pre-chemotherapy levels at the end of treatment. These results indicate T cell subset distributions associated with recurrence may be largely resistant to being “re-set” to healthy control homeostatic levels following standard treatments. However, it may be possible to enhance T effector to Treg ratios transiently during chemotherapy. These results suggest personalized immune monitoring maybe beneficial when combining novel immuno-therapeutics with standard treatment for ovarian cancer patients.

In this pilot study, we observed increased levels of recently activated Tregs with tumor migrating ability (CD4+CD25hiFoxp3+CD127−CCR4+CD38+ cells) in patients when compared to controls. Although frequency changes of Tregs as well as the ratio of effector T cells to Tregs were observed during treatment, the Tregs consistently returned to pre-chemotherapy levels at the end of treatment. These results indicate T cell subset distributions associated with recurrence may be largely resistant to being “re-set” to healthy control homeostatic levels following standard treatments. However, it may be possible to enhance T effector to Treg ratios transiently during chemotherapy. These results suggest personalized immune monitoring maybe beneficial when combining novel immuno-therapeutics with standard treatment for ovarian cancer patients. PMID:24213326

    The recombinant form of tissue plasminogen activator (rt-PA) is the only curative treatment for ischemic stroke. Recently, t-PA has been linked to the metabolism of brain-derived neurotrophic factor (BDNF), a major neurotrophin involved in post-stroke neuroplasticity. Thus, the objective of our study was to investigate the impact of rt-PA treatment on post-stroke circulating BDNF levels in humans and in animals. Serum BDNF levels and t-PA/plasmin activity were measured at hospital admission a...

    Brain-derived neurotrophic factor (BDNF) regulates the survival and growth of neurons, and influences synaptic efficiency and plasticity. Peripheral BDNF levels in patients with schizophrenia have been widely reported in the literature. However, it is still controversial whether peripheral levels of BDNF are altered in patients with schizophrenia. The peripheral BDNF levels previously reported in patients with schizophrenia were total BDNF (proBDNF and mature BDNF) as it was unable to specifically measure mature BDNF due to limited BDNF antibody specificity. In this study, we examined whether peripheral levels of mature BDNF were altered in patients with treatment-resistant schizophrenia. Matrix metalloproteinase-9 (MMP-9) levels were also measured, as MMP-9 plays a role in the conversion of proBDNF to mature BDNF. Twenty-two patients with treatment-resistant schizophrenia treated with clozapine and 22 age- and sex-matched healthy controls were enrolled. The plasma levels of mature BDNF and MMP-9 were measured using ELISA kits. No significant difference was observed for mature BDNF however, MMP-9 was significantly increased in patients with schizophrenia. The significant correlation was observed between mature BDNF and MMP-9 plasma levels. Neither mature BDNF nor MMP-9 plasma levels were associated clinical variables. Our results do not support the view that peripheral BDNF levels are associated with schizophrenia. MMP-9 may play a role in the pathophysiology of schizophrenia and serve as a biomarker for schizophrenia.

    Once-monthly administration of CERA, a continuous erythropoietin receptor activator, has shown equivalent efficacy to shorter-acting erythropoiesis-stimulating agents (ESAs) that require more frequent dosing, but data on routine use of once-monthly CERA in hemodialysis patients are lacking. Study on Efficacy, Safety and Applicability of Mircera (SESAM) was a prospective, multicenter, noninterventional trial with a duration of up to 9 months (month 0-5 "titration phase"; month 6-8 "evaluation phase") to test the stability of Hb control in hemodialysis patients under routine conditions. Patient selection, Hb targets and CERA dosing were at the discretion of the local nephrologist. 918 patients from 92 German nephrology centers were included. Ninety-three percent were on ESA treatment prior to study entry. The mean number of CERA dose changes during the study was 1.9 ± 1.9 per patient. Mean Hb level was 11.4 ± 1.2 g/dL at baseline and 11.7 ± 1.4 g/dL at the end of the 8-month study. During the evaluation phase (months 6-8), 15.6%, 40.3%, and 66.0% of patients had stable Hb (i.e., at least two values) in the ranges 11-12, 10-12, and 10-13 g/dL, respectively. The mean intra-individual fluctuation in Hb was 1.4 ± 0.7 g/dL during the study (0.5 ± 0.4 g/dL during the 3-month evaluation phase). More than 90% of patients, and > 80% of physicians, rated CERA therapy as "very good" or "good" throughout the study. Four patients (0.4%) discontinued prematurely due to adverse drug reactions. Once-monthly CERA therapy maintains stable Hb values with low intra-individual variability and few dose adaptations in hemodialysis patients when administered entirely according to local practice, and the regimen was well-tolerated.

    To determine patient, treatment, or facility characteristics that influence decisions to initiate a rehabilitation assessment before transtibial or transfemoral amputation within the Veterans Affairs (VA) health care system. Retrospective database study. VA medical centers. A total of 4226 veterans with lower extremity amputations discharged from a VA medical center between October 1, 2002, and September 30, 2004. Evidence of a preoperative rehabilitation assessment after the index surgical stay admission but before the surgical date. Evidence was found that 343 of 4226 veterans (8.12%) with lower extremity amputations received preoperative rehabilitation assessments. Veterans receiving preoperative rehabilitation were more likely to be older, admitted from home, or transferred from another hospital. Patients who underwent surgical amputation at smaller-sized hospitals or in the South Central or Mountain Pacific regions were more likely to receive preoperative rehabilitation compared with patients in mid-sized hospitals or in the Northeast, Southeast, or Midwest regions. Patients with evidence of paralysis, patients treated in facilities with programs accredited by the Commission on Accreditation of Rehabilitation Facilities (P facility-level structural characteristics, we found that older patients were more likely to receive preoperative rehabilitation services (odds ratio [OR] 1.01, 95% confidence interval [CI] 1.01-1.02). Patients with a contributing amputation etiology of a previous amputation complication were more likely to receive preoperative consultation rehabilitation services (OR 1.50, 95% CI 1.02-2.19) compared with patients who did not have this etiology. Compared with patients treated in the Southeast region of the United States, those treated in the South Central region (OR 2.52, 95% CI 1.82-3.48) or Mountain Pacific region (OR 1.62, 95% CI 1.11-2.37) were more likely to receive preoperative consultation rehabilitation services.

    Indacaterol was evaluated versus placebo, formoterol, and salmeterol in randomized controlled trials. No direct comparisons, however, are available for indacaterol 150 μg with formoterol or indacaterol 300 μg with salmeterol. Indacaterol trial evidence was synthesized to provide coherent estimates of indacaterol 150 μg and indacaterol 300 μg relative to formoterol, salmeterol, and tiotropium. Four randomized controlled trials were combined with Bayesian mixed treatment comparisons by using individual patient-level data. End points of interest were trough forced expiratory volume in 1 second (FEV(1)), St. George's Respiratory Questionnaire (SGRQ) total score and response (≥ 4 points), and Transition Dyspnea Index total score and response (≥ 1 point). Indacaterol 150 μg demonstrated a higher FEV(1) than did formoterol at 12 weeks and 6 months (0.10 L difference; 95% credible interval [CrI] = 0.06-0.14), as did indacaterol 300 μg versus salmeterol (0.06 L difference at 12 weeks; CrI = 0.02-0.10; 0.06 L at 6 months; CrI = 0.02-0.11). Regarding SGRQ, indacaterol 150 μg demonstrated a comparable proportion of responders versus formoterol, as did indacaterol 300 μg versus salmeterol. In comparison to tiotropium, indacaterol 150 μg demonstrated a greater proportion of responders (odds ratio = 1.52 at 12 weeks; CrI 1.15-2.00). For Transition Dyspnea Index, indacaterol 150 μg and formoterol showed a similar response. Indacaterol 300 μg was more efficacious than salmeterol (odds ratio = 1.65 at 12 weeks; CrI 1.16-2.34). Overall, indacaterol 150 μg showed the greatest efficacy for SGRQ and indacaterol 300 μg for FEV(1) and Transition Dyspnea Index. Indacaterol is expected to be comparable to formoterol, salmeterol, and tiotropium, providing higher FEV(1) than formoterol and salmeterol and greater improvement in the SGRQ total score than tiotropium. Indacaterol 150 μg provided comparable improvement in dyspnea, while indacaterol 300 μg demonstrated the

    To investigate the use of “Control Point Analysis” (Sun Nuclear Corporation, Melbourne, FL) to analyze and compare delivered volumetric-modulated arc therapy (VMAT) plans for 3 different treatment planning complexity levels. A total of 30 patients were chosen and fully anonymized for the purpose of this study. Overall, 10 lung stereotactic body radiotherapy (SBRT), 10 head-and-neck (H and N), and 10 prostate VMAT plans were generated on Pinnacle{sup 3} and delivered on a Varian linear accelerator (LINAC). The delivered dose was measured using ArcCHECK (Sun Nuclear Corporation, Melbourne, FL). Each plan was analyzed using “Sun Nuclear Corporation (SNC) Patient 6” and “Control Point Analysis.” Gamma passing percentage was used to assess the differences between the measured and planned dose distributions and to assess the role of various control point binning combinations. Of the different sites considered, the prostate cases reported the highest gamma passing percentages calculated with “SNC Patient 6” (97.5% to 99.2% for the 3%, 3 mm) and “Control Point Analysis” (95.4% to 98.3% for the 3%, 3 mm). The mean percentage of passing control point sectors for the prostate cases increased from 51.8 ± 7.8% for individual control points to 70.6 ± 10.5% for 5 control points binned together to 87.8 ± 11.0% for 10 control points binned together (2%, 2-mm passing criteria). Overall, there was an increasing trend in the percentage of sectors passing gamma analysis with an increase in the number of control points binned together in a sector for both the gamma passing criteria (2%, 2 mm and 3%, 3 mm). Although many plans passed the clinical quality assurance criteria, plans involving the delivery of high Monitor Unit (MU)/control point (SBRT) and plans involving high degree of modulation (H and N) showed less delivery accuracy per control point compared with plans with low MU/control point and low degree of modulation (prostate)

    Following wildfires, forest managers often consider salvage logging burned trees to recover monetary value of timber, reduce fuel loads, or to meet other objectives. Relatively little is known about the cumulative hydrologic effects of wildfire and subsequent timber harvest using logging equipment. We used controlled rill experiments in logged and unlogged (control) forests burned at high severity in northern Montana, eastern Washington, and southern British Columbia to quantify rill overland flow and sediment production rates (fluxes) after ground-based salvage logging. We tested different types of logging equipment-feller-bunchers, tracked and wheeled skidders, and wheeled forwarders-as well as traffic levels and the addition of slash to skid trails as a best management practice. Rill experiments were done at each location in the first year after the fire and repeated in subsequent years. Logging was completed in the first or second post-fire year. We found that ground-based logging using heavy equipment compacted soil, reduced soil water repellency, and reduced vegetation cover. Vegetation recovery rates were slower in most logged areas than the controls. Runoff rates were higher in the skidder and forwarder plots than their respective controls in the Montana and Washington sites in the year that logging occurred, and the difference in runoff between the skidder and control plots at the British Columbia site was nearly significant (p = 0.089). Most of the significant increases in runoff in the logged plots persisted for subsequent years. The type of skidder, the addition of slash, and the amount of forwarder traffic did not significantly affect the runoff rates. Across the three sites, rill sediment fluxes were 5-1900% greater in logged plots than the controls in the year of logging, and the increases were significant for all logging treatments except the low use forwarder trails. There was no difference in the first-year sediment fluxes between the feller

    Hsuan-Ho Chen

    Full Text Available The levels of squamous cell carcinoma antigen (SCC-Ag and C-reactive protein (CRP can be used to predict tumor invasion, lymph node metastasis, staging and survival in patients with oral cavity cancer. The present study analyzed the relationship between pre-treatment levels of SCC-Ag and CRP in relation to clinicopathological factors in patients with pharyngolaryngeal cancer (PLC and determined whether elevated levels of CRP and SCC-Ag were associated with tumor metabolic activity via [18F] fluorodeoxyglucose positron emission tomography (FDG-PET. We retrospectively recruited one hundred and six PLC patients between June 2008 and December 2011. All patients received computed tomography (CT/magnetic resonance imaging (MRI and FDG-PET staging analyses, and the serum levels of SCC-Ag and CRP in these patients were measured prior to treatment. A SCC-Ag level ≥2.0 ng/ml and a CRP level ≥5.0 mg/L were significantly associated with clinical stage (P<0.001, clinical tumor status (P<0.001, and clinical nodal status (P<0.001. The elevation of both SCC-Ag and CRP levels was correlated with the standardized uptake value (SUV max of the tumor (≥8.6 mg/L and lymph nodes (≥5.7 ng/ml (P = 0.019. The present study demonstrated that the presence of high levels of both pre-treatment SCC-Ag and CRP acts as a predictor of clinical stage, clinical tumor status, and clinical nodal status in patients with PLC. Moreover, elevated levels of SCC-Ag and CRP were associated with a high metabolic rate as well as the proliferative activity measured according to the SUVmax of the tumor and lymph nodes. Therefore, elevated levels of these two factors have the potential to serve as biomarkers for the prediction of tumor aggressiveness in cases of PLC.

We investigated the kinetics of MT markers during anti-HCV and anti-HIV treatments, and if baseline plasma levels of lipopolysaccharide (LPS, lipopolysaccharide binding protein (LBP and soluble CD14 (sCD14 could predict anti-HCV treatment outcome.Plasma from 78 HIV-infected patients was evaluated for LPS, LBP and sCD14. The patients starting anti-HCV treatment (with ongoing antiretroviral (ART treatment were categorized into sustained viral responders (SVR; n = 21 or non-responders (NR; n = 15 based on treatment outcome. ART starting subjects--were categorized into chronically HCV-infected (CH; n = 24 and mono-infected (HIV; n = 18, based on the HCV infection status. Samples were collected before start (at baseline of pegylated-interferon-alpha/ribavirin (peg-IFN/RBV or antiretroviral-therapy and two years after treatment start (at follow up. χ2-test, non-parametric statistics and logistic regression were applied to determine the associations with treatment response and changes of the soluble markers.Plasma levels of LPS and sCD14 were elevated in all subjects before antiviral-treatment but remained unchanged at follow-up. Elevated levels of LBP were present in patients with HIV and HIV/HCV co-infection and were reduced by ART. Additionally, higher levels of LBP were present at baseline in NR vs. SVR. Higher levels of LBP at baseline were associated with non-response to peg-IFN/RBV treatment in both bivariate (OR: 0.19 95% CI: 0.06-0.31, p = 0.004 and multivariate analysis (OR: 1.43, 95% CI: 1.1-1.86, p = 0.07.In HIV/HCV co-infected patients high baseline LBP levels are associated with non-response to peg-IFN/RBV therapy. Plasma LBP (decreased by ART may be a more relevant MT marker than LPS and sCD14.

  2. Multi-country analysis of treatment costs for HIV/AIDS (MATCH: facility-level ART unit cost analysis in Ethiopia, Malawi, Rwanda, South Africa and Zambia.

    Full Text Available BACKGROUND: Today's uncertain HIV funding landscape threatens to slow progress towards treatment goals. Understanding the costs of antiretroviral therapy (ART will be essential for governments to make informed policy decisions about the pace of scale-up under the 2013 WHO HIV Treatment Guidelines, which increase the number of people eligible for treatment from 17.6 million to 28.6 million. The study presented here is one of the largest of its kind and the first to describe the facility-level cost of ART in a random sample of facilities in Ethiopia, Malawi, Rwanda, South Africa and Zambia. METHODS & FINDINGS: In 2010-2011, comprehensive data on one year of facility-level ART costs and patient outcomes were collected from 161 facilities, selected using stratified random sampling. Overall, facility-level ART costs were significantly lower than expected in four of the five countries, with a simple average of $208 per patient-year (ppy across Ethiopia, Malawi, Rwanda and Zambia. Costs were higher in South Africa, at $682 ppy. This included medications, laboratory services, direct and indirect personnel, patient support, equipment and administrative services. Facilities demonstrated the ability to retain patients alive and on treatment at these costs, although outcomes for established patients (2-8% annual loss to follow-up or death were better than outcomes for new patients in their first year of ART (77-95% alive and on treatment. CONCLUSIONS: This study illustrated that the facility-level costs of ART are lower than previously understood in these five countries. While limitations must be considered, and costs will vary across countries, this suggests that expanded treatment coverage may be affordable. Further research is needed to understand investment costs of treatment scale-up, non-facility costs and opportunities for more efficient resource allocation.

    The aim of this research was to assess tertiary student distress levels with regards to (i) comparisons with normative population data, and (ii) the effects of discipline, year level, and student characteristics. Self-reported treatment rates and level of concern regarding perceived distress were also collected. Students from all six years of an undergraduate medical course were compared with samples from Psychology, Law and Mechanical Engineering courses at the University of Adelaide, Australia. Students participated in one of three studies that were either web-based or paper-based. All studies included Kessler's Measure of Psychological Distress (K10), and questions pertaining to treatment for any mental health problems and concern regarding distress experienced. Of the 955 tertiary students who completed the K10, 48% were psychologically distressed (a K10 score > or = 22) which equated to a rate 4.4 times that of age-matched peers. The non-health disciplines were significantly more distressed than the health disciplines. Distress levels were statistically equivalent across all six years of the medical degree. Of tertiary students, 11% had been treated for a mental health problem. Levels of concern correlated with the K10 score. The results from this research suggest that high distress levels among the tertiary student body may be a phenomenon more widely spread than first thought. Low treatment rates suggest that traditional models of support may be inadequate or not appropriate for tertiary cohorts.

    The long-term effect of cinacalcet hydrochloride treatment on parathyroid gland (PTG) volume has been scarcely investigated in patients with moderate to advanced secondary hyperparathyroidism (SHPT). The present study was a prospective observational study to determine the effect of cinacalcet treatment on PTG volume and serum biochemical parameters in 60 patients with renal SHPT, already treated with intravenous vitamin D receptor activator (VDRA). Measurement of biochemical parameters and PTG volumes were performed periodically, which were analyzed by stratification into tertiles across the baseline parathyroid hormone (PTH) level or PTG volume. We also determined the factors that can estimate the changes in PTG volume and the achievement of the target PTH range by multivariable analyses. Two years of cinacalcet treatment significantly decreased the serum levels of PTH, calcium, and phosphate, followed by the improvement of achieving the target ranges for these parameters recommended by the Japanese Society for Dialysis Therapy. Cinacalcet decreased the maximal and total PTG volume by about 30%, and also decreased the serum PTH level independent of the baseline serum PTH level and PTG volume. Ten out of 60 patients showed 30% increase in maximal PTG after 2 years. Multivariable analysis showed that patients with nodular PTG at baseline and patients with higher serum calcium and PTH levels at 1 year were likely to exceed the target range of PTH at two years. In conclusion, cinacalcet treatment with intravenous VDRA therapy decreased both PTG volume and serum intact PTH level, irrespective of the pretreatment PTG status and past treatment history. © 2015 The Authors.

    Full Text Available This study is done to evaluate the effect of spleen tyrosine kinase inhibitor (BAY 61-3606, cyclin-dependent kinase inhibitor (CDKi, and sodium butyrate (Na-Bu on the level and phosphorylation of p53 protein and its binding to murine double minute 2 (MDM2 homologue in human vestibular schwannomas (VS. Primary cultures of the tumor tissues were treated individually with optimum concentrations of these small molecules in vitro. The results indicate modulation of p53 protein status and its binding ability to MDM2 in treated samples as compared to the untreated control. The three individual treatments reduced the level of total p53 protein. These treatments also decreased Ser392 and Ser15 phosphorylated p53 in tumor samples of young patients and Ser315 phosphorylated p53 in old patients. Basal level of Thr55 phosphorylated p53 protein was present in all VS samples and it remained unchanged after treatments. The p53 protein from untreated VS samples showed reduced affinity to MDM2 binding in vitro and it increased significantly after treatments. The MDM2/p53 ratio increased approximately 3-fold in the treated VS tumor samples as compared to the control. The differential p53 protein phosphorylation status perhaps could play an important role in VS tumor cell death due to these treatments that we reported previously.

  7. Immunomodulation Induced by Stem Cell Mobilization and Harvesting in Healthy Donors: Increased Systemic Osteopontin Levels after Treatment with Granulocyte Colony-Stimulating Factor

    2016-07-01

    Full Text Available Peripheral blood stem cells from healthy donors mobilized by granulocyte colony-stimulating factor (G-CSF and harvested by leukapheresis are commonly used for allogeneic stem cell transplantation. The frequency of severe graft versus host disease is similar for patients receiving peripheral blood and bone marrow allografts, even though the blood grafts contain more T cells, indicating mobilization-related immunoregulatory effects. The regulatory phosphoprotein osteopontin was quantified in plasma samples from healthy donors before G-CSF treatment, after four days of treatment immediately before and after leukapheresis, and 18–24 h after apheresis. Myeloma patients received chemotherapy, combined with G-CSF, for stem cell mobilization and plasma samples were prepared immediately before, immediately after, and 18–24 h after leukapheresis. G-CSF treatment of healthy stem cell donors increased plasma osteopontin levels, and a further increase was seen immediately after leukapheresis. The pre-apheresis levels were also increased in myeloma patients compared to healthy individuals. Finally, in vivo G-CSF exposure did not alter T cell expression of osteopontin ligand CD44, and in vitro osteopontin exposure induced only small increases in anti-CD3- and anti-CD28-stimulated T cell proliferation. G-CSF treatment, followed by leukapheresis, can increase systemic osteopontin levels, and this effect may contribute to the immunomodulatory effects of G-CSF treatment.

  8. Post-cold war United Nations peacekeeping operations: a review of the case for a hybrid level 2+ medical treatment facility.

    Johnson, Ralph Jay

    2015-01-01

    Post-Cold War, UN peacekeeping operations (UN PKOs) have become larger, more mobile, multi-faceted and conducted over vast areas of remote, rugged, and harsh geography. They have been increasingly involved in dangerous areas with ill-defined boundaries, simmering internecine armed conflict, and disregard on the part of some local parties for peacekeepers' security and role. Yet progressively there have been expectations of financial restraint and austerity. Additionally, UN PKOs have become more "robust," that is, engaged in preemptive, assertive operations. A statistically positive and significant relationship exists between missions' size, complexity, remoteness, and aggressive tenor and a higher probability of trauma or death, especially as a result of hostile actions or disease. Therefore, in the interest of "force protection" and optimizing operations, a key component of UN PKOs is health care and medical treatment. The expectation is that UN PKO medical support must conform to the general intent and structure of current UN PKOs to become more streamlined, portable, mobile, compartmentalized, and specialized, but also more varied and complex to address the medical aspects of these missions cost-efficiently. This article contends that establishing a hybrid level 2-a level 2 with level 3 modules and components (i.e., level 2+)-is a viable course of action when considering trends in the medical aspects of Post-Cold War UN PKOs. A level 2 medical treatment facility has the potential to provide needed forward mobile medical treatment, especially trauma care, for extended, complex, large-scale, and comprehensive UN PKOs. This is particularly the case for missions that include humanitarian outreach, preventive medicine, and psychiatry. The level 2 treatment facility is flexible enough to expand into a hybrid level 2+ with augmentation of modules based on changes in mission requirements and variation in medical aspects.

    Conclusion: On-treatment complete virological response at Month 6 is a favorable factor predictive of HBeAg loss at 2 years of entecavir therapy. Therefore, measurement of serum HBV-DNA level at 6 months of entecavir therapy is optimal to predict HBeAg loss at 2 years of therapy in HBeAg-positive CHB patients.
