    Background: Ovarian epithelial cancer (OEC) usually presents in the later stages of the disease. Factors, especially those associated with cell-cycle genes, affecting the genesis and tumour progression for ovarian cancer are largely unknown. We hypothesized that over-expressed transcription factors (TFs), as well as those that are driving the expression of the OEC over-expressed genes, could be the key for OEC genesis and potentially useful tissue and serum markers for malignancy associated with OEC.Methods: Using a combination of computational (selection of candidate TF markers and malignancy prediction) and experimental approaches (tissue microarray and western blotting on patient samples) we identified and evaluated E2F5 transcription factor involved in cell proliferation, as a promising candidate regulatory target in early stage disease. Our hypothesis was supported by our tissue array experiments that showed E2F5 expression only in OEC samples but not in normal and benign tissues, and by significantly positively biased expression in serum samples done using western blotting studies.Results: Analysis of clinical cases shows that of the E2F5 status is characteristic for a different population group than one covered by CA125, a conventional OEC biomarker. E2F5 used in different combinations with CA125 for distinguishing malignant cyst from benign cyst shows that the presence of CA125 or E2F5 increases sensitivity of OEC detection to 97.9% (an increase from 87.5% if only CA125 is used) and, more importantly, the presence of both CA125 and E2F5 increases specificity of OEC to 72.5% (an increase from 55% if only CA125 is used). This significantly improved accuracy suggests possibility of an improved diagnostics of OEC. Furthermore, detection of malignancy status in 86 cases (38 benign, 48 early and late OEC) shows that the use of E2F5 status in combination with other clinical characteristics allows for an improved detection of malignant cases with sensitivity

    AIM: To explore the expression pattern of E2F5 in primary hepatocellular carcinomas (HCCs) and elucidate the roles of E2F5 in hepatocarcinogenesis. METHODS: E2F5 expression was analyzed in 120 primary HCCs and 29 normal liver tissues by immunohistochemistry analysis. E2F5-small interfering RNA was transfected into HepG2, an E2F5-overexpressed HCC cell line. After E2F5 knockdown, cell growth capacity and migrating potential were examined. RESULTS: E2F5 was significantly overexpressed in primary HCCs compared with normal liver tissues (P = 0.008). The E2F5-silenced cells showed significantly reduced proliferation (P = 0.004). On the colony formation and soft agar assays, the number of colonies was significantly reduced in E2F5-silenced cells (P = 0.004 and P = 0.009, respectively). E2F5 knockdown resulted in the accumulation of G0/G1 phase cells and a reduction of S phase cells. The number of migrating/invading cells was also reduced after E2F5 knockdown (P = 0.021). CONCLUSION: To our knowledge, this is the first evidence that E2F5 is commonly overexpressed in primary HCC and that E2F5 knockdown significantly repressed the growth of HCC cells.

    Long noncoding RNAs (lncRNAs) have been proved to play important roles in cellular processes of cancer, including the development, proliferation, and migration of cancer cells. In the present study, we demonstrated small nucleolar RNA host gene 16 (SNHG16) as an oncogene on cell migration in breast cancer. Expression levels of SNHG16 were found to be frequently higher in breast cancer tissues than in the paired noncancerous tissues. Gain- and loss-of-function studies proved that SNHG16 significantly promoted breast cancer cell migration. We predicted SNHG16 as a competitive endogenous RNA (ceRNA) of E2F transcription factor 5 protein (E2F5) via competition for the shared miR-98 through bioinformatics analysis, and proved this regulation using relative quantitative real-time PCR (qRT-PCR), western blot, RNA immunoprecipitation (RIP) assay and luciferase reporter assay. In addition, we identified a positive correlation between SNHG16 and E2F5 in breast cancer tissues. Furthermore, we demonstrated that forced expression of miR-98 could partially abrogate SNHG16-mediated increase of breast cancer cells migration, suggesting that SNHG16 promoted cell migration in a miR-98 dependent manner. Taken together, our findings indicated that SNHG16 induces breast cancer cell migration by competitively binding miR-98 with E2F5, and SNHG16 can serve as a potential therapeutic target for breast cancer treatment.

    High-risk papillomavirus type 18 (HPV18) is one of the less represented HPV types in low-grade lesions of the anogenital tract, whereas it occupies the second place in cervical cancer, where it can be found in 16% of the cases worldwide, after HPV16 present in 54% of them. These epidemiological data indicate that HPV18 infection is more prone to carcinogenic progression. The main oncogenic proteins, E6 and E7 of HPV18, are functionally comparable to the homologous proteins of the other high-risk viruses, including HPV16. In this work, we investigated the possibility that the higher oncogenic potential of HPV18 might be due to transcriptional regulation of the E6/E7 oncogenes. By comparing the E6/E7 promoter and enhancer sequences of the mucosal HPV genomes, we identified E2F binding sites specific for HPV18. The E2F family of transcription factors contains activators (E2F1-3) and repressors (E2F4-8) that regulate the transcription of S-phase and mitotic genes and thereby have a crucial role in cell-cycle progression. Surprisingly, we identified E2F5 as a direct activator of HPV18 E6/E7 transcription by sequential silencing of E2F members in HeLa cells. In addition, we could show that E2F5 positively regulates S-phase entry in HeLa cells and that this activation of the cell cycle by a member of the E2F repressor family is specific for HPV18-expressing cells. Diverting the function of E2F5 from a cell-cycle repressor into an activator might contribute to the higher oncogenic potential of HPV18 when compared with other high-risk HPV types.

    The E2F transcription factors play a role in regulating the expression of genes required for cell proliferation. Their activity appears to be regulated by association with the retinoblastoma protein (pRb) and the pRb-related proteins p107 and p130. In vivo, pRb is found in complex with a subset of E2F components--namely, E2F-1, E2F-2, and E2F-3. Here we describe the characterization of cDNAs encoding two unusual E2Fs, E2F-4 and E2F-5, each identified by the ability of their gene product to in...

    p53 mutations have profound effects on non-small-cell lung cancer (NSCLC) resistance to chemotherapeutic treatments. Mutant p53 proteins are usually expressed at high levels in tumors, where they exert oncogenic functions. Here we show that p53R175H, a hotspot p53 mutant, induces microRNA (miRNA)-128-2 expression. Mutant p53 binds to the putative promoter of miR128-2 host gene, ARPP21, determining a concomitant induction of ARPP21 mRNA and miR-128-2. miR-128-2 expression in lung cancer cells inhibits apoptosis and confers increased resistance to cisplatin, doxorubicin and 5-fluorouracyl treatments. At the molecular level, miR-128-2 post-transcriptionally targets E2F5 and leads to the abrogation of its repressive activity on p21waf1 transcription. p21waf1 protein localizes to the cytoplasmic compartment, where it exerts an anti-apoptotic effect by preventing pro-caspase-3 cleavage. This study emphasizes miRNA-128-2 role as a master regulator in NSCLC chemoresistance. PMID:22193543

    Full Text Available Abstract Background Despite increased funding of measles vaccination programs by national governments and international aid agencies, structural factors encumber attainment of childhood measles immunisation to levels which may guarantee herd immunity. One of such factors is parental education status. Research on the links between parental education and vaccination has typically focused on the influence of maternal education status. This study aims to demonstrate the independent influence of paternal education status on measles immunisation. Methods Comparable nationally representative survey data were obtained from six countries with the highest numbers of children missing the measles vaccine in 2008. Logistic regression analysis was applied to examine the influence of paternal education on uptake of the first dose of measles vaccination, independent of maternal education, whilst controlling for confounding factors such as respondent’s age, urban/rural residence, province/state of residence, religion, wealth and occupation. Results The results of the analysis show that even if a mother is illiterate, having a father with an education of Secondary (high school schooling and above is statistically significant and positively correlated with the likelihood of a child being vaccinated for measles, in the six countries analysed. Paternal education of secondary or higher level was significantly and independently correlated with measles immunisation uptake after controlling for all potential confounders. Conclusions The influence of paternal education status on measles immunisation uptake was investigated and found to be statistically significant in six nations with the biggest gaps in measles immunisation coverage in 2008. This study underscores the imperative of utilising both maternal and paternal education as screening variables to identify children at risk of missing measles vaccination prospectively.

    Oxidative stress is involved in a variety of diseases. Prospective studies investigating the relationship between oxidative stress biomarkers and the status and development of colorectal cancer (CRC) are scarce; previous studies have failed to establish a relationship between the serum total oxidant/antioxidant status and CRC. Therefore, we compared the total serum oxidant/antioxidant levels of CRC patients and healthy subjects, and analyzed their clinical significance in the CRC. Fasting blood samples from 132 CRC patients and 64 healthy subjects were collected. Oxidative stress parameters, including total oxidant status (TOS) and total antioxidant status (TAS), were measured, and the oxidative stress index (OSI) was calculated. The TOS and OSI levels increased significantly (POxidative stress parameters differed significantly depending on the patient's smoking and drinking status (P0.05).However, the levels of TOS, TAS, and OSI were significantly different between patients with no metastasis and those with metastases to two organs (P<0.05) Finally, the parameters are affected by smoking and drinking, and subsequent research should be conducted excluding the relevant influencing factors.

    Full Text Available Abstract Background The aim of the present work was to investigate the relative importance of socio-demographic and physical health status factors for subjective functioning, as well as to examine the role of social support. Methods A cross-sectional health survey was carried out in a Greek municipality. 1356 adults of the general population were included in the study. Personal interviews were conducted with house-to-house visits. The response rate was 91.2%. Functioning has been measured by five indexes: 'The Social Roles and Mobility' scale (SORM, 'The Self-Care Restrictions' scale (SCR, 'The Serious Limitations' scale (SL, 'The Minor Self-care Limitations' scale (MSCR and 'The Minor Limitations in Social Roles and Mobility' scale (MSORM. Results Among the two sets of independent variables, the socio-demographic ones had significant influence on the functional status, except for MSORM. Allowing for these variables, the physical health status indicators had also significant effects on all functioning scales. Living arrangements and marital status had significant effects on four out of five indexes, while arthritis, Parkinson's disease, past stroke and kidney stones had significant effects on the SCR and SL scales. Conclusions These results suggest that socio-demographic factors are as important as physical health variables in affecting a person's ability to function normally in their everyday life. Social support appears to play a significant role in explaining differences in subjective functioning: people living alone or only with the spouse, particularly the elderly, seem to be in greater risk for disability problems and should be targeted by preventive programs in the community.

    Increased knowledge of molecular alterations involved in gastric carcinogenesis has provided useful information for diagnosis and prediction. In this study, we investigated the clinicopathological significance of TFF3 expression and Her-2/neu status in gastric adenocarcinoma and explored the correlation between TFF3 expression and Her-2/neu status. A hundred and twenty-six (126) patients having undergone curative gastrectomy were enrolled. Immunohistochemistry for TFF3 was performed on tumor tissues and non-neoplastic resection margins. Her-2/neu status was assessed by immunohistochemical staining and fluorescence in situ hybridization (FISH) on tumor tissues. As a result, TFF3 expression and Her-2/neu positivity were detected in 46.8% and 11.9% of the cases, respectively. Patients with negative TFF3 exhibited longer survival than the positive group (P=0.0142), while patients with positive Her-2/neu only showed a tendency toward longer overall survival (P>0.05). However, Her-2/neu was significantly associated with improved disease-free survival (P=0.0234). Multivariate analysis demonstrated Her-2/neu and TFF3 to be independent prognostic indicators of recurrence, and a significantly poor prognosis for expression of TFF3 in patients with Her-2/neu negative tumors. TFF3 is an independent indicator for overall survival in gastric cancer, while Her-2/neu, as a marker of long time survival prediction, seems to be limited.

    E2F DNA binding sites are found in a number of genes whose expression is tightly regulated during the cell cycle. The activity of E2F transcription factors is regulated by association with specific repressor molecules that can bind and inhibit the E2F transactivation domain. For E2F-1, E2F-2, and E2F-3, the repressor is the product of the retinoblastoma gene, pRb. E2f-4 interacts with pRb-related p107 and not with pRb itself. Recently, a cDNA encoding a third member of the retinoblastoma gene...

    Background We aimed to identify the clinical and echocardiographic determinants of symptoms and their prognostic implications in patients with moderately dysfunctional bicuspid aortic valves (BAVs). Methods Among 1,019 subjects in the BAV registry treated in a single tertiary care center, the records of 127 patients (85 men, age 58±13 years) with moderately dysfunctional BAVs were comprehensively reviewed. The patients were divided into two groups based on symptom status: asymptomatic (n = 80) vs. symptomatic (n = 47). The primary end-point was defined as a composite of aortic valve surgery, hospitalization for heart failure, and any cause of death. Results The symptomatic group had a higher proportion of females, hypertension, aortic stenosis, and aortopathy than did the asymptomatic group. The symptomatic group showed lower e′ (5.5±1.7 vs. 6.5±2.2 cm/s, p = 0.003), higher E/e′ (13.3 ± 4.9 vs. 10.9±3.7, p = 0.002), and larger left atrial volume index (29.9±11.4 vs. 24.6±9.1 ml/m2, p = 0.006) than did the asymptomatic group. In multivariate logistic regression analysis, female gender (odds ratio [OR] 2.84, 95% confidence interval [CI] 1.10–7.36, p = 0.031), hypertension (OR 3.07, 95% CI 1.20–7.82, p = 0.019), moderate aortic stenosis (OR 5.33 5.78, 95% CI 1.99–16.83, p = 0.001), E/e′ >15 (OR 3.82, 95% CI 1.03–11.19, p = 0.015), and aortopathy (OR 2.76, 95% CI 1.07–7.10, p = 0.035) were independently correlated with symptom status. The symptomatic group showed a significantly lower rate of event-free survival during the 8-year follow-up period (54±9% vs. 68±10%, p = 0.001). Conclusions In patients with moderately dysfunctional BAVs, the presence of moderate aortic stenosis, aortopathy, and diastolic dysfunction determines symptom status, along with female gender and hypertension. Symptom status was associated with clinical outcomes. PMID:28060855

  17. Combining Chromosomal Arm Status and Significantly Aberrant Genomic Locations Reveals New Cancer Subtypes

    Full Text Available Many types of tumors exhibit characteristic chromosomal losses or gains, as well as local amplifications and deletions. Within any given tumor type, sample specific amplifications and deletions are also observed. Typically, a region that is aberrant in more tumors, or whose copy number change is stronger, would be considered as a more promising candidate to be biologically relevant to cancer. We sought for an intuitive method to define such aberrations and prioritize them. We define V, the “volume” associated with an aberration, as the product of three factors: (a fraction of patients with the aberration, (b the aberration’s length and (c its amplitude. Our algorithm compares the values of V derived from the real data to a null distribution obtained by permutations, and yields the statistical significance (p-value of the measured value of V. We detected genetic locations that were significantly aberrant, and combine them with chromosomal arm status (gain/loss to create a succinct fingerprint of the tumor genome. This genomic fingerprint is used to visualize the tumors, highlighting events that are co-occurring or mutually exclusive. We apply the method on three different public array CGH datasets of Medulloblastoma and Neuroblastoma, and demonstrate its ability to detect chromosomal regions that were known to be altered in the tested cancer types, as well as to suggest new genomic locations to be tested. We identified a potential new subtype of Medulloblastoma, which is analogous to Neuroblastoma type 1.

    AIM: To investigate oxidative stress and lipid peroxi-dation in hepatic steatosis and the underlying implica-tions in pathological mechanisms of non-alcoholic fatty liver disease (NAFLD).METHODS: F2-isoprostanes (iPF2α-Ⅲ) in blood and liver samples from steatotic (n = 9) and control (n = 7)rats were measured as in vivo marker of lipid peroxida-tion by a mass spectrometric approach. The lipid pro-file and endogenous antioxidant status (SOD and CAT)in the rats were also analyzed.RESULTS: Significantly higher levels of iPF2α-Ⅲ (mean3.47 vs 2.40 pmol/mg tissue, P = 0.004) and lower activities of SOD (mean 1.26 U vs 1.40 U, P < 0.001) and CAT (mean 1026.36 U/mg vs 1149.68 U/mg pro-tein, without significance) were observed in the livers of steatotic rats. Plasma total iPF2α-Ⅲ was significantly correlated with the abnormalities of blood lipids as well as alanine aminotransferase (ALT) levels in the rats with simple steatosis, whereas no similar tendencies were observed in the control rats.CONCLUSION: Enhancement of hepatic oxidative imbalance occurring at the steatotic stage of NAFLD suggests a possibility that manifestation of the local oxidative damage precedes that of systemic oxidativeimbalance. Predominant metabolic features of the in-creased lipid peroxidation further suggest a close asso-ciation of the oxidative imbalance and the dyslipidemia with functional deterioration of the steatotic liver. The findings need to be further evaluated, especially in hu-man studies.

    Aerial and interview surveys were conducted in 1986 to determine the current distribution, status, and traditional significance of the West Indian manatee Trichechus manatus in Venezuela. Aerial surveys provided just eight tentative sightings in 73 hours of searching. These discouraging results may have been due to poor visibility, small populations, and perhaps reduced dry season manatee activity. Results of interview surveys, however, permitted a number of important generalizations. A remnant manatee population exists in Lake Maracaibo, but none occur along the more than 1500 km of Caribbean coastline. Abundance is greatest in eastern Venezuela bordering the Golfo de Paria, in the Orinoco Delta, and in the middle Orinoco and tributaries. Local market hunting in the middle of this century probably greatly reduced manatee populations in these areas. Recent protection laws, education efforts, and manatee scarcity have resulted in a declining interest in manatee hunting. Much excellent manatee habitat persists in these regions, and a continued decline in hunting could result in an optimistic outlook for future manatee populations if the incidental take in net fisheries is controlled. Traditional beliefs and legends concerning manatees in Venezuela, including hunting taboos, show that these animals remain a colorful part of the folk culture. However, manatee protection does not pose economic hardships or infringe upon traditional spiritual beliefs.

    Full Text Available The essay focuses on the relevance of the labour law regulation's personal scope, what the holistic approach of employee status and its social part mean. There have been discussions in the European Union to which circle of working people shall the protection system of labour law apply, and how the security of employees can be guaranteed under the pressure of flexibility. The debates have been inspired by a changed economic and social environment in the XXth centrury. The essay presents the influence of the changing economic and social environment in the concept of employee status, and more closer in the Hungarian labour law regulation. The decision who is acknowledged to be an employee is made by the legislator. By making this decision the labour law regulation shows a tendency of withdrawal and moving forward in the last decades. The change of employment contract develops at the same time with the expansion of personal scope in Europe and shows a great variety. The legislation, judicial practice, legal practice and the collective bargaining influence the expansion of protection under labour law. The changes of personal scope in the Labour Code of 1992 and 2012 are presented, how it is extended and in which direction. The personal scope is also applied to link the public and private sector by finding a common focal point: the characteristics of employment. While coping with the employment relations on the labour market and trying to fit into the self-employed - employee-like person - employee categories, it is suggested to exceed the contractual framework by means of abstraction and using the concept of personal work relations. Employee status has social part; therefore the essay describes the social consequences of being employee and its relation to the employee status.

    Obesity is a well-known atherosclerosis risk factor; however, its role and the importance of undernutrition in atrial fibrillation (AF) pathogenesis are still not well understood. The aim of this study was to present the current state of knowledge on this issue in different groups of patients. Systematic review of papers published between 1980 and 2016. The literature shows contradicting views regarding the impact of nutritional status on the risk, course, and complications of AF. On the one hand, it has been revealed that overweight, obesity, and high birth mass increase the risk of AF, and that their reduction is linked to an improved course of AF and reduced all-cause and cardiovascular mortality. On the other hand, a so-called obesity paradox has been found, which shows lower all-cause mortality in overweight patients with AF compared to those of normal weight or who are underweight. It has also been shown, although based on a small number of studies, that the relationship between nutritional status and risk of AF and its complication may be U-shaped, which means that not only patients with obesity, but also individuals with underweight, cachexia, and low birth weight may have an increased risk and poor outcome of AF. The relationship between patients' nutritional status and the course of AF has become clearer but it requires further studies examining the importance of weight reduction on AF course.

    Full Text Available This study was carried out in the adjacent communities of the Hakaluki haor, the largest inland freshwater wetland of Bangladesh to explore their socio-economic status and haor-based livelihood dependency. Hakaluki haor is a poverty stricken region with 37% households falling into extreme poor group having monthly income of Tk 2 000.00 only. More than half of the community view Hakaluki haor as the vital source of livelihoods. The surrounding community is dependent on the haor in varying degree (15% totally dependent, 32% moderately and 53% less with a variety of livelihood activities like fishing and related profession (32%, duck rearing (29%, cattle rearing (28%, fuel wood collection (6%, sand extraction (3% and reed collection (2%. The average annual household incomes from fishing of naturally available fish, pisciculture and NTFPs collection are Tk 21 701.35, Tk 31 524.83 and Tk 2 704.80, respectively. The haor serves as the source of fuel for cooking to a majority of the community (48%. The respondents identified over-exploitation of fish resources, use of excessive pesticides and gradual increase of human settlement in and around the haor as the most threatened events. With the designation as Ecologically Critical Area (ECA by the government, immediate attempts should be taken to ensure sustainable utilization of the haor resources. Development of integrated management plan with a provision of the participation of local stakeholders may become the possible way of conserving this wetland.This study was carried out in the adjacent communities of the Hakaluki haor, the largest inland freshwater wetland of Bangladesh to explore their socio-economic status and haor-based livelihood dependency.

    This study examines the prognostic significance of hypoxia inducing factor-1α (HIF-1α) expression in relation to human papillomavirus (HPV) status in oropharyngeal squamous cell carcinoma (SCC). Clinical details on 233 oropharyngeal SCCs were extracted from institutional databases. Recurrence in any form or death from any cause was recorded for a median of 51 months after diagnosis. HIF-1α expression was evaluated by semiquantitative immunohistochemistry and HPV status was determined by HPV E6-targeted multiplex real-time PCR and p16 immunohistochemistry. Determinants of recurrence and mortality hazards were modeled using Cox regression with censoring at dates of last follow-up. The HIF-1α positivity rate was 58.8%. HIF-1α positivity was associated with higher T category (T3/T4 vs. T1/T2, 64.2% vs. 48.4%, p=0.001) and lower grade (Grade 1-2 vs. 3, 62% vs. 46.9%, p=0.001). There was no significant association between HIF-1α expression and HPV status. After adjustment for clinico-pathological variables, HPV status but not HIF-1α was a strong predictor of outcome. The combination of HPV and HIF-1α was not a prognostic variable but the worst outcomes were seen in those with HPV negative and HIF-1α positive cancers. There was no statistically significant evidence of an interaction between HPV and HIF-1α. The degree of hypoxia as measured by HIF-1α expression does not differ between HPV positive and HPV negative cancers. The role of hypoxia in HPV negative oropharyngeal cancer warrants further investigation. Crown Copyright © 2012. Published by Elsevier Ltd. All rights reserved.

    Objective To observe the expression of inlfammatory molecules in bone marrow immune cells of patients with immune-related hematocytopenia (IRH), and to investigate the immune mechanism and clinical signiifcance of the disease. Methods Total of 36 IRH patients were selected as observation group and 30 healthy people were taken as control group. Serum cytokines levels, activity of immunocytes and expression of HLA-DR were detected. Immune lfuorescence was applied to observe the expression state of immunologic molecules and cytokines in IRH patients. Results Serum cytokines were elevated in various degrees in observation group. Compared with the control group, the cytokines levels were significantly higher (P Conclusions It is demonstrated that antibodies or self-reactive lymphocytes were produced in IRH marrow, which would cause lesions of hemocytes, and lead to pathological process ifnally. Structure of hematopoietic cells mutated and these cells might be acted as target cells of immunocytes in the pathological process. Immunocytes could secrete inlfammatory factors and lead to immunologic injury of hemocyte.

    To analyze the status of DACH1 gene promoter methylation and explore its association with the expression of DACH1 gene promoter methylation and clinical significance of endometrium carcinoma (EC). From February 2004 to August 2008, a total of 80 EC tissue samples with comprehensive surgical pathology staging were collected and used for this study. Twenty normal endometrium tissues in 2008 were abstained from the fractional curettage because of dysfunctional uterine bleeding as control. All samples were confirmed pathologically. Methylation specific PCR (MSP) was performed to detect the promoter methylation of DACH1 gene, and analyze its influence on the expression of DACH1 and the relationship between DACH1 promoter methylation and clinicopathological factors in EC. DACH1 protein expression was detected by western blot. Chi-square test and Pearson test were used for statistical analysis. The rate of promoter methylation of DACH1 gene in the EC tissues was significantly higher than that in the normal endometrium issues (30% vs. 5%, P promoter methylation (r = -0.30, P 0.05). DACH1 gene promoter methylaion could lead to a decrease or absence in the DACH1 expression in EC. The promoter methylation of DACH1 gene may induce the inhibition of DACH1 expression, which might be one of the mechanisms of DACH1 gene inactivation in human EC.

    Equol, a metabolite of the dietary isoflavone daidzein, is produced by the action of gut bacteria in some individuals who are termed as equol-producers. It is proposed to have stronger atheroprotective properties than dietary isoflavones. We examined a cross-sectional association of dietary isoflavones and equol-producer status with coronary artery calcification (CAC), a biomarker of coronary atherosclerosis, among men in Japan. A population-based sample of 272 Japanese men aged 40-49 years recruited from 2004 to 2007 was examined for serum isoflavones, serum equol, CAC and other factors. Equol-producers were classified as individuals having a serum level of equol >83 nm. The presence of CAC was defined as a coronary Ca score ≥10 Agatston units. The associations of dietary isoflavones and equol-producers with CAC were analysed using multiple logistic regression. The median of dietary isoflavones, equol and CAC were 512·7 (interquartile range (IQR) 194·1, 1170·0), 9·1 (IQR 0·10, 33·1) and 0·0 (IQR 0·0, 1·0) nm, respectively. Prevalence of CAC and equol-producers was 9·6 and 16·0 %, respectively. Dietary isoflavones were not significantly associated with CAC. After multivariable adjustment, the OR for the presence of CAC in equol-producers compared with equol non-producers was 0·10 (95 % CI 0·01, 0·90, PCAC than equol non-producers, but there was no significant association between dietary isoflavones and CAC, suggesting that equol may be a key factor for atheroprotective properties of isoflavones in Japanese men. This finding must be confirmed in larger studies or clinical trials of equol that is now available as a dietary supplement.

    Socio demographic factors besides dietary factors play important role in determining the health status of an individual. Health and nutritional Intervention programs stand a greater chance of success if planned, keeping the socio demographic characteristics of a certain population in focus. The present study was conducted to identify those socio demographic determinants which have a significant association with poor nutritional status in adolescent girls belonging to economically deprived households of Lahore. A cross-sectional analytical study of 140 adolescent girls living in the peri urban communities of Lahore was conducted. Socioeconomic and demographic data of the participants was recorded through a pretested questionnaire. Body mass index (BMI), a commonly used anthropometric measurement was taken as an indicator of nutritional status. Below normal (socio demographic variables were calculated and Fisher Exact test was used to find out the association of nutritional status with socio-demographic predictors. Stepwise backward logistic regression analysis was then run to identify the most significant determinants associated with poor nutritional status in the adolescents. P food insecure (AOR = 0.431; 95% CI = 0.164 to 1.133) had lesser odds of having poor nutritional status than those who lived in nuclear families and were food secure. Frequency of illness, house ownership and fathers' education are the determinants positively associated with poor nutritional status of adolescent girls. Food insecurity and joint family structure were negatively associated with poor nutritional status. The study will help in planning interventions for improving nutritional status of adolescent girls by targeting the significant socio demographic determinants of poor nutritional status among this group.

    Human solid tumors frequently have a relatively small growth fraction,which interferes with the action of many chemotherapeutic agents that target actively cycling cells. Several polyamine analogues are currently being developed for clinical application against human solid tumors including N1,N11-bis(ethyl)norspermine. Therefore, an effort was made to examine the effects of growth rate on polyamine-analogue efficacy. Low growth fraction (LGF) cell cultures of the human non-small cell lung cancer cell line NCI-H157 were generated to partially mimic solid tumors with low mitotic indices. Log-phase cells were compared with LGF cells with respect to cell survival and biochemical effects after exposure to polyamine analogues. The results demonstrate generally that LGF NCI-H157 cells were sensitive to analogue treatment. However, the dose necessary to elicit a response in LGF cells was an order of magnitude higher than the dose needed in log-phase cells. Additionally, the biochemical effects of analogues were similar between log phase and LGF cells with regard to a down-regulation of polyamine biosynthesis as measured by ornithine decarboxylase activity and an increase in polyamine catabolism as indicated by an increase in spermidine/spermine N1-acetyltransferase activity. However, biochemical effects were less dramatic in the LGF cells than those observed in the log-phase cells. The overall results of these studies suggest that the growth status of solid tumors can significantly affect the response to antitumor polyamine analogues, and growth fraction must be considered in the continued development and use of the polyamine analogues.

    Surgical treatment strategies for proximal femur metastasis have been reported with mixed results. Little is known about risk factor for implant failure except for longer patient survival. Therefore, we determined whether implant survivorship differed among treatment strategies, as well as risk factors for implant failure. We retrospectively reviewed a consecutive 106 patients with proximal femur metastasis treated with prosthesis replacement (n = 38), intramedullary nail (n = 32), and dynamic hip screw (DHS) (n = 36). Eastern Cooperative Oncology Group (ECOG) scale and Karnofsky index were used to evaluate functional outcome. Patient characteristics and postoperative ambulatory performance status were assessed for their values in determining implant failure. Overall implant failure rate was 11.3% (12 of 106). Prosthesis replacement was related to better implant survivorship (P = 0.041), without mechanical failures. On the contrary, 7 of the 10 implant failures in the fixation group were considered mechanical failures. Better postoperative ambulatory status (ECOG ≤ 2) was a risk factor for implant failure (P = 0.03). Notably, for patients with poor ambulatory status (ECOG ≥ 3), implant survivorship was not different among choice of implants. In conclusion, prosthesis replacement would be a more durable option in the treatment of proximal femur metastasis. Postoperative ambulatory status could be an additional consideration. For patients with poor expected ambulatory performance status, fixation with intramedullary nail or DHS might be considered for a less technical demanding procedure.

  14. Garden and landscape-scale correlates of moths of differing conservation status: significant effects of urbanization and habitat diversity.

    Directory of Open Access Journals (Sweden)

    Adam J Bates

    Full Text Available Moths are abundant and ubiquitous in vegetated terrestrial environments and are pollinators, important herbivores of wild plants, and food for birds, bats and rodents. In recent years, many once abundant and widespread species have shown sharp declines that have been cited by some as indicative of a widespread insect biodiversity crisis. Likely causes of these declines include agricultural intensification, light pollution, climate change, and urbanization; however, the real underlying cause(s is still open to conjecture. We used data collected from the citizen science Garden Moth Scheme (GMS to explore the spatial association between the abundance of 195 widespread British species of moth, and garden habitat and landscape features, to see if spatial habitat and landscape associations varied for species of differing conservation status. We found that associations with habitat and landscape composition were species-specific, but that there were consistent trends in species richness and total moth abundance. Gardens with more diverse and extensive microhabitats were associated with higher species richness and moth abundance; gardens near to the coast were associated with higher richness and moth abundance; and gardens in more urbanized locations were associated with lower species richness and moth abundance. The same trends were also found for species classified as increasing, declining and vulnerable under IUCN (World Conservation Union criteria. However, vulnerable species were more strongly negatively affected by urbanization than increasing species. Two hypotheses are proposed to explain this observation: (1 that the underlying factors causing declines in vulnerable species (e.g., possibilities include fragmentation, habitat deterioration, agrochemical pollution across Britain are the same in urban areas, but that these deleterious effects are more intense in urban areas; and/or (2 that urban areas can act as ecological traps for some

    Full Text Available BACKGROUND: Nutrition is one of many factors affecting the cognitive development of children. In Cambodia, 55% of children <5 y were anemic and 40% stunted in 2010. Currently, no data exists on the nutritional status of Cambodian school-aged children, or on how malnutrition potentially affects their cognitive development. OBJECTIVE: To assess the anthropometric and micronutrient status (iron, vitamin A, zinc, iodine of Cambodian schoolchildren and their associations with cognitive performance. METHODS: School children aged 6-16 y (n = 2443 from 20 primary schools in Cambodia were recruited. Anthropometry, hemoglobin, serum ferritin, transferrin receptors, retinol-binding protein and zinc concentrations, inflammation status, urinary iodine concentration and parasite infection were measured. Socio-economic data were collected in a sub-group of children (n = 616. Cognitive performance was assessed using Raven's Colored Progressive Matrices (RCPM and block design and picture completion, two standardized tests from the Wechsler Intelligence Scale for Children (WISC-III. RESULTS: The prevalence of anemia, iron, zinc, iodine and vitamin A deficiency were 15.7%; 51.2%, 92.8%, 17.3% and 0.7% respectively. The prevalence of stunting was 40.0%, including 10.9% of severe stunting. Stunted children scored significantly lower than non-stunted children on all tests. In RCPM test, boys with iron-deficiency anemia had lower scores than boys with normal iron status (-1.46, p<0.05. In picture completion test, children with normal iron status tended to score higher than iron-deficient children with anemia (-0.81; p = 0.067 or without anemia (-0.49; p = 0.064. Parasite infection was associated with an increase in risk of scoring below the median value in block design test (OR = 1.62; p<0.05, and with lower scores in other tests, for girls only (both p<0.05. CONCLUSION: Poor cognitive performance of Cambodian school-children was multifactorial and

    The Sundanese inhabiting West Java, the second largest ethnic group in Indonesia, are characterized by a high prevalence of child malnutrition, together with high fertility. Based on an anthropometric measurement and interview survey of 310 children aged 5-12 years in a rural Sundanese village, this study examined the relative significance of the effects of eight biological, eight socioeconomic status (SES) and four health behavioural factors on their Z scores for height-for-age (HAZ) and weight-for-age (WAZ) in particular. Three biological factors, i.e. birth interval, birth weight and mother's body weight, and one SES factor, i.e. mother's occupation, were selected as the predictors of the two Z scores by regression analysis, indicating more significant effects of the biological factors than the other factors. This pattern is judged to occur in less-developed and high-fertility populations. Since these two Z scores were worse in the subject children than in the under-5-year-old children from the same village, more attention should be paid to the long-lasting effects of birth-related biological factors up to pre-adolescent ages, as an insufficient nutritional status tends to damage growth and health in adolescence and adulthood.

    We investigated whether glomerular hemodynamic parameters in nondiabetic subjects, including healthy subjects, are associated with glycemic status indices, by simultaneous measurement of inulin (Cin) and para-aminohippuric acid (CPHA) clearance. Twenty-six subjects (age 49.5 ± 13.3 years; 13 men and 13 women; 14 healthy subjects and 12 subjects with mild proteinuria) were enrolled. Cin and CPAH were measured simultaneously. All 26 subjects were nondiabetics. Estimated preglomerular resistance, estimated postglomerular resistance, and estimated glomerular hydrostatic pressure (Pglo) were calculated according to Gomez' formula. Pglo correlated significantly and positively with hemoglobin A1c (HbA1c) in both healthy subjects (r = 0.532, P = 0.0498) and subjects with mild proteinuria (r = 0.681, P = 0.015). While there was no significant correlation between estimated preglomerular resistance and HbA1c, estimated postglomerular resistance correlated significantly and positively with HbA1c both in healthy subjects (r = 0.643, P = 0.013) and subjects with mild proteinuria (r = 0.589, P = 0.044). Glomerular filtration fraction, estimated Pglo and estimated postglomerular resistance in total subjects were associated significantly with HbA1c after adjustment for age, gender, and body mass index. These results demonstrate that, even in nondiabetic subjects, glycemic status is associated with estimated postglomerular resistance, but not estimated preglomerular resistance. It is suggested that increased estimated postglomerular resistance associated with higher HbA1c levels, even within the normal range, causes increased estimated Pglo, leading to increased FF. Thus, hemodynamic abnormalities associated with higher HbA1c levels may be related to glomerular hypertension, even in nondiabetic subjects.

    Full Text Available Fetal growth restriction or intrauterine growth restriction is one of the leading causes of perinatal mortality and morbidity in newborns. Fetal growth restriction is a complex multifactorial condition resulting from several fetal and maternal disorders. The objective of this study was twofold: first to examine the correlation between maternal parameters such as body mass index (BMI, nutritional status, anemia, and placental weight and diameter, and their effects on fetal growth and then to evaluate the effect of early screening by ultrasonography (USG on the outcome of growth restricted pregnancies. In this study, 53 cases of fetal growth restriction were compared to 53 normal fetuses delivered in consecutive sequence. Growth restricted fetuses were delivered earlier in gestation, when compared with normal growth fetuses. Maternal anemia and malnutrition have significant association with the fetal growth restriction. Maternal anthropometry, such as low BMI, had effects on placental diameter and weight, which, in turn, adversely affected fetal weight. Thus, early USG screening along with robust screening for maternal BMI, nutritional status, and anemia can assist the obstetric team in providing early diagnosis, prompt intervention, and better outcome in pregnancy with fetal growth restriction.

    Full Text Available The association of socioeconomic status (SES with nutrient intake attracts public attention worldwide. In the current study, we examined the associations of SES with dietary intake of folate and health outcomes in general Japanese workers. This Japanese occupational cohort consisted off 2266 workers. SES was assessed by a self-administered questionnaire. Intakes of all nutrients were assessed with a validated, brief and self-administered diet history questionnaire (BDHQ. The degree of depressive symptoms was measured by the validated Japanese version of the K6 scale. Multiple linear regression and stratified analysis were used to evaluate the associations of intake with the confounding factors. Path analysis was conducted to describe the impacts of intake on health outcomes. Education levels and household incomes were significantly associated with intake of folate and depression scales (p < 0.05. After adjusting for age, sex and total energy intake, years of education significantly affect the folate intake (β = 0.117, p < 0.001. The structural equation model (SEM shows that the indirect effect of folate intake is statistically significant and strong (p < 0.05, 56% of direct effect in the pathway of education level to depression scale. Our study shows both education and income are significantly associated with depression scales in Japanese workers, and the effort to increase the folate intake may alleviate the harms of social disparities on mental health.

    Full Text Available Aim. Despite high levels of malnutrition, there is still very little information on the nutritional benefits of Spirulina, a natural alga that provides essential amino acids, rare essential lipids, and numerous minerals and vitamins, to undernourished children in the world. Methods. We carried out a prospective study of 50 children aged between six and 60 months. The intervention group consisted of 16 children who received 10 g of Spirulina daily, as well as the local diet administered by the nutritional centre, and the control group of 34 children who just received the local diet. Both groups of children were assessed on day zero, day 15, and day 30. Results. After treatment, the weight-for-age Z scores and weight-for-height Z scores increased significantly in the intervention group. At day 15, there was a statistically significant difference between the mean corpuscular volume, total proteins, and albumin (p<0.05 in both groups, in favour of the intervention group, and at day 30, this difference extended to all of the studied parameters (p<0.05. Conclusion. This study found that the nutritional status of undernourished children who received Spirulina supplements as well as the local diet administered by the nutritional centre improved quickly and significantly.

    Social subordination in macaques is a well-established model to study the adverse effects of psychosocial stress on a number of health outcomes, including stress-induced eating. The present analysis was conducted to empirically define a meal among free-feeding female rhesus monkeys and to examine the roles of meal patterning (e.g., meal size, meal frequency, and snacking patterns) in findings from a previous study demonstrating that psychosocial stress increases overall caloric intake among subordinate animals with access to a highly palatable diet. Results indicate that all animals, regardless of social status, consumed more frequent meals, larger meals, and more calories in the form of snacks when a highly palatable diet was available. Additional findings suggest that subordinate animals consumed significantly larger meals compared to their dominant counterparts regardless of the dietary environment. Additionally, subordinate females with a history of exposure to the palatable diet consumed significantly more snack calories than both dominant and subordinate animals without previous exposure to the palatable diet when these females were returned to a standard laboratory diet. These findings illustrate how small changes in meal patterns can lead to significant increases in total caloric intake, which if prolonged, could promote the emergence of an obese phenotype.

    Brunilde Gril

    Full Text Available Pazopanib is an FDA approved Vascular Endothelial Growth Factor Receptor inhibitor. We previously reported that it also inhibits tumor cell B-Raf activity in an experimental brain metastatic setting. Here, we determine the effects of different B-Raf genotypes on pazopanib efficacy, in terms of primary tumor growth and anti-angiogenesis. A panel of seven human breast cancer and melanoma cell lines harboring different mutations in the Ras-Raf pathway was implanted orthotopically in mice, and tumor growth, ERK1/2, MEK1/2 and AKT activation, and blood vessel density and permeability were analyzed. Pazopanib was significantly inhibitory to xenografts expressing either exon 11 mutations of B-Raf, or HER2 activated wild type B-Raf; no significant inhibition of a xenograft expressing the common V600E B-Raf mutation was observed. Decreased pMEK staining in the responsive tumors confirmed that B-Raf was targeted by pazopanib. Interestingly, pazopanib inhibition of tumor cell B-Raf also correlated with its anti-angiogenic activity, as quantified by vessel density and area. In conclusion, using pazopanib, tumor B-Raf status was identified as a significant determinant of both tumor growth and angiogenesis.

    Aim. Despite high levels of malnutrition, there is still very little information on the nutritional benefits of Spirulina, a natural alga that provides essential amino acids, rare essential lipids, and numerous minerals and vitamins, to undernourished children in the world. Methods. We carried out a prospective study of 50 children aged between six and 60 months. The intervention group consisted of 16 children who received 10 g of Spirulina daily, as well as the local diet administered by the nutritional centre, and the control group of 34 children who just received the local diet. Both groups of children were assessed on day zero, day 15, and day 30. Results. After treatment, the weight-for-age Z scores and weight-for-height Z scores increased significantly in the intervention group. At day 15, there was a statistically significant difference between the mean corpuscular volume, total proteins, and albumin (p Spirulina supplements as well as the local diet administered by the nutritional centre improved quickly and significantly.

    Full Text Available The social amoeba Dictyostelium discoideum is widely studied for its multicellular development program as a response to starvation. Aggregates of up to 106 cells form fruiting bodies containing (i dormant spores (~80% that can persist for months in the absence of nutrients, and (ii dead stalk cells (~20% that promote the dispersion of the spores towards nutrient-rich areas. It is often overlooked that not all cells aggregate upon starvation. Using a new quantitative approach based on time-lapse fluorescence microscopy and a low ratio of reporting cells, we have quantified this fraction of non-aggregating cells. In realistic starvation conditions, up to 15% of cells do not aggregate, which makes this third cell fate a significant component of the population-level response of social amoebae to starvation. Non-aggregating cells have an advantage over cells in aggregates since they resume growth earlier upon arrival of new nutrients, but have a shorter lifespan under prolonged starvation. We find that phenotypic heterogeneities linked to cell nutritional state bias the representation of cells in the aggregating vs. non-aggregating fractions, and thus affect population partitioning. Next, we report that the fraction of non-aggregating cells depends on genetic factors that regulate the timing of starvation, signal sensing efficiency and aggregation efficiency. In addition, interactions between clones in mixtures of non-isogenic cells affect the partitioning of each clone into both fractions. We further build a numerical model to test the evolutionary significance of the non-aggregating cell fraction. The partitioning of cells into aggregating and non-aggregating fractions is optimal in fluctuating environments with an unpredictable duration of starvation periods. Our study highlights the unicellular component of the response of social amoebae to starvation, and thus extends its evolutionary and ecological framework.

    Full Text Available Thrombocytosis portends adverse prognostic significance in many types of cancers including ovarian and lung carcinoma. In this study, we determined the prevalence and prognostic significance of thrombocytosis (defined as platelet count in excess of 400 × 103/μl in patients with colorectal cancer. We performed a retrospective analysis of 310 consecutive patients diagnosed at our Institution between 2004 and 2013. The patients (48.7% male and 51.3% female had a mean age of 69.9 years (+/- 12.7 years at diagnosis. Thrombocytosis was found in a total of 25 patients, with a higher incidence in those with stage III and IV disease (14.4% of patients. Although the mean platelet count increased with the depth of tumor invasion (pT, its values remained within normal limits in the whole patient cohort. No patient with stage I cancer (n=57 had elevated platelet count at diagnosis. By contrast, five of the 78 patients (6.4% with stage II cancer showed thrombocytosis, and four of these patients showed early recurrence and/or metastatic disease, resulting in shortened survival (they died within one year after surgery. The incidence of thrombocytosis increased to 12.2% and 20.6%, respectively, in patients with stage III and IV disease. The overall survival rate of patients with thrombocytosis was lower than those without thrombocytosis in the stage II and III disease groups, but this difference disappeared in patients with stage IV cancer who did poorly regardless of their platelet count. We concluded that thrombocytosis at diagnosis indicates adverse clinical outcome in colorectal cancer patients with stage II or III disease. This observation is especially intriguing in stage II patients because the clinical management of these patients is controversial. If our data are confirmed in larger studies, stage II colon cancer patients with thrombocytosis may be considered for adjuvant chemotherapy.

  12. Comprehensive analysis of HPV16 integration in OSCC reveals no significant impact of physical status on viral oncogene and virally disrupted human gene expression.

    Directory of Open Access Journals (Sweden)

    Nadine C Olthof

    Full Text Available Infection with high-risk human papillomavirus (HPV type 16 is an independent risk factor for the development of oropharyngeal squamous cell carcinomas (OSCC. However, it is unclear whether viral integration is an essential hallmark in the carcinogenic process of OSCC and whether HPV integration correlates with the level of viral gene transcription and influences the expression of disrupted host genes. We analyzed 75 patients with OSCC. HPV16-positivity was proven by p16(INK4A immunohistochemistry, PCR and FISH. Viral integration was examined using DIPS- as well as APOT-PCR. Viral E2, E6 and E7 gene expression levels were quantified by quantitative reverse transcriptase (RT-qPCR. Expression levels of 7 human genes disrupted by the virus were extracted from mRNA expression profiling data of 32 OSCCs. Viral copy numbers were assessed by qPCR in 73 tumors. We identified 37 HPV16-human fusion products indicating viral integration in 29 (39% OSCC. In the remaining tumors (61% only episome-derived PCR products were detected. When comparing OSCC with or without an integration-derived fusion product, we did not find significant differences in the mean RNA expression of viral genes E2, E6 and E7 or the viral copy numbers per cell, nor did the RNA expression of the HPV-disrupted genes differ from either group of OSCC. In conclusion, our data do not support the hypothesis that integration affects the levels of viral and/or HPV-disrupted human gene transcripts. Thus constitutive, rather than a high level, of expression of oncogene transcripts appears to be required in HPV-related OSCC.

    Full Text Available BACKGROUND: Children are the precious possession of the family, community and the country. Nearly 200 million (30%, are malnourished in the world and over 2/3rd of malnourished are in Asia. Every 3rd underfed child in the world lives in India. India is home to 40% of world’s malnourished children. According to global hunger index India ranks 117th of 119 countries in malnutrition. OBJECTIVE: 1. To find the prevalence of PEM among 1-6 year children. 2. To assess the knowledge of the mothers regarding adequate nutrition and its association to undernourishment. METHODS: Cross-sectional study among 150 children was undertaken for a period of 1 month from June to July 2014 at urban slums of old Hubli. Knowledge of mother was assessed by questionnaire, scores were assigned to responses and clinical examination of child along with anthropometry was carried out. RESULTS: Obtained by WHO Anthro Plus software through Z-scores, which showed 24.6% were moderately and 13.4% severely undernourished by weight and 22% were moderately and 25.4% severely stunted. Birth weight of child had significant (P<0.05 association with undernourishment. Knowledge scores regarding nutrition among mothers was good among 35.3%, moderate in 38.7% and poor in 26%, its correlation to undernourishment was significant (p<0.001. Pearson’s correlation, showed a positive linear relationship between knowledge and nourishment and Linear Regression model established knowledge as a significant variable having independent and direct influence on nutritional status of child (p<0.001. CONCLUSION: Parent’s literacy, knowledge and child’s birth weight has a direct impact on child’s nutritional status. Education and awareness is the key to progress.

    To investigate the accuracy of colposcopy for diagnosing high-grade squamous intraepithelial lesion (HSIL) or worse (HSIL+) in human papillomavirus (HPV)-infected patients with atypical squamous cells of undetermined significance (ASCUS) cytology, and determine whether genotyping and viral load quantitation can be useful for detecting immediate HSIL+ risk in these patients. This study included 620 cases with ASCUS and positive for high-risk (HR)-HPV within 1 month before or after cervical cytology at Qilu Hospital between February 2013 and February 2014. Based on the colposcopic impression, lesion-targeted punch biopsy, endocervical curettage biopsy or random cervical punch biopsy in four quadrants was performed on these patients within 1 month. The accuracy of colposcopy for diagnosing HSIL+ was evaluated through comparison with the biopsy results. HR-HPV status determined by Hybrid Capture 2 or HPV genotyping was analysed retrospectively as a possible predictor of HSIL+. Agreement between colposcopic impression and cervical pathology was matched perfectly in 89.2% of cases (553/620), and the strength of agreement with the κ statistic was 0.698 (ptypes of HPV (17.9%, pbiopsies considering HPV-16 infection or virus load ≥50 RLU/CO may be helpful for increasing the HSIL+ detection rate.

    The quantitation of estrogen and progesterone receptors (ER and PgR) has become the standard of care in the evaluation of patients with primary breast carcinoma. It has been demonstrated that ER and PgR detected by immunohistochemical methods in formalin-fixed paraffin-embedded tissue can be quantified by computerized image analysis. In this study, ER and PgR levels were determined by using an automated immunochemistry stainer (Ventana ES 320) and an image analyzer (CAS 200) in a series of 236 patients with stage I/II carcinoma of the breast. The degree of correlation of the ER and PgR levels determined by the dextran-coated charcoal method (DCC) with image analysis quantitation was high (r=0.75). The agreement between both methods was 77% for ER and 73% for PgR. Hormone receptor levels were correlated with prognosis as determined by overall survival. An ER level of 30 fmol/mg as determined by image analysis was established to stratify the patient population most effectively into favorable and unfavorable prognostic groups (P=0.003). An ER level of 20 fmol/mg for prognostic stratification reached statistical significance (P=0.03). The DCC method was not able to stratify the patients into prognostic groups at the traditionally accepted cutpoint of 10 fmol/mg (P=0.52). We conclude that when used in combination, automated immunohistochemistry and quantitative image analysis offer a favorable alternative to the DCC method in assessment of ER and PgR status in human mammary carcinoma. In addition, quantitative immunocytochemistry techniques may prove superior to the DCC method in specimens in which there is limited tumor volume (including fine-needle aspirates), stroma-rich tumors, and early-stage lesions including intraductal carcinoma.

    Objective To clarify the difference and significance of ceruloplasmin levels in patients with Wilson's disease and chronic hepatitis B patients with different liver function status. Methods Model for end-stage liver disease (MELD) was used to measure severities of liver function injury. The levels of ceruloplasmin in patients with Wilson' s disease, patients at the fastigium and convalescent period of acute-on-chronic liver failure with hepatitis B and in patients with chronic hepatitis B were measured by nephelometric immunoassay. Results The MELD scores in patients with Wilson' s disease (re =50) , fastigum and convalescent period of acute-on-chronic liver failure with hepatitis B (n = 30) , chronic hepatitis B (re =50) were 11.1 ?. 5 , 20. 4 ?. 2 , 10.9 ?.9 and 9. 6 ?. 8, respectively, and the levels of ceruloplasmin in those patients were (0.065 ?.036)g/L, (0. 176 ?.037)g/L, (0.210 ?.056)g/L and (0. 197 ?. 038 ) g/L, respectively. There were statistically significant differences among the four groups(F=111.4 , P <0.001). The level of ceruloplasmin in Wilson's disease patients was significant lower than that in the other groups (P<0.001). Conclusion Ceruloplasmin level is remarkably decreased in patients with Wilson's disease. Compared with Wilson's disease, ceruloplasmin level is almost normal in patients with chronic hepatitis B without liver failure. Ceruloplasmin level just is decreased slightly at the fastigium of acute-on-chronic liver failure with hepatitis B and returned to normal level along with the recovery of liver failure.%目的 探讨肝豆状核变性、乙型肝炎不同肝功能状态时血浆铜蓝蛋白水平的差异及其临床意义.方法 用终末期肝病模型(model for end-stage liver disease,MELD)评分衡量肝功能损害的严重性,采用散射比浊法检测并比较分析肝豆状核变性、慢加急性肝衰竭极期以及恢复期、慢性乙型肝炎患者的血浆铜蓝蛋白水平.结果 肝豆状核变性(n=50)、慢加

    Full Text Available Recently, “tribocorrosion,” a research area combining the science of tribology and corrosion, has drawn attention from scientists and engineers belonging to a wide spectrum of research domains. This is due to its practical impact on daily life and also the accompanying economical burdens. It encompasses numerous applications including the offshore, space, and biomedical industry, for instance, in the case of artificial joints (Total Hip Replacement, THR in orthopedic surgery, where implant metals are constantly exposed to tribological events (joint articulations in the presence of corrosive solutions, that is, body fluids. Keeping the importance of this upcoming area of research in biomedical applications in mind, it was thought to consolidate the work in this area with some fundamental aspects so that a comprehensive picture of the current state of knowledge can be depicted. Complexity of tribocorrosion processes has been highlighted, as it is influenced by several parameters (mechanical and corrosion and also due to the lack of an integrated/efficient test system. Finally a review of the recent work in the area of biotribocorrosion is provided, by focusing on orthopedic surgery and dentistry.

    2010-01-01

    Full Text Available Introduction. Convulsive status epilepticus is the most urgent neurological medical emergency in children. Generalized convulsive status epilepticus is the most common and life-threatening type of status epilepticus. It is not a syndrome in the same sense as febrile convulsions, benign rolandic epilepsy, and infantile polymorphic epilepsy. These latter disorders have a tight age frame, seizure semiology, and a reasonably predictable outcome. Episodes of convulsive status epilepticus can occur in each: occasionally in symptomatic and febrile convulsions, and Lennox Gastaut syndrome, rarely in benign rolandic epilepsy, and West syndrome. Etiology of convulsive status epilepticus. Status epilepticus has many causes, which vary depending on the age and patient population. Convulsive status epileptucus continues to be associated with significant neurological morbidity and mortality, with different hazards and outcome. Although the outcome is dependent on etiology, it is known that appropriate early management may reduce mortality and some of the morbidity associated with convulsive status epilepticus. Discussion. Status epilepticus is a disorder in which the mechanisms attempting at terminating the seizure fail. Continued convulsive activity in convulsive status epilepticus results in decompensation of all organs and systems, thus being life threatening. Seizure activity in convulsive status epilepticus is associated with neuronal damage. The aim should be to halt this activity urgently, using, ideally, a 100% effective drug, administered quickly, without compromising the consciousness level or producing other negative effects on cardiovascular, respiratory function or other unexpected effects.

This research is an explorative and descriptive study on the socio-cultural aspects of food system. The data were collected through a direct interview and discussion with respondents as well as a direct observation at the location of respondents. A sample size of 338 households was drawn from the population. To obtain the data on the cultural aspects, history and  socio aspect of food, in-depth interviews was conducted with 19 key persons. The study was last for 12 months. In Outer Baduy, the factors significantly related to nutritional status are age, number of household size, income, nutritional knowledge, and wife’s ability to read. In Moslem Baduy, only age and income are related to the nutritional status of children. In Moslem Baduy and the Outer Baduy, the correlation between age and W/A or W/H is similar: namely, the higher the age, the lower would the Z-score for the W/A or W/H. The income is significantly correlated to the child nutritional status according to Z-score for W/A with a high correlation coefficient, that is, 0.61. This means that the higher the income, the higher would be the Z-score value for the W/A.  The distribution of adults according to BMI classification in Outer Baduy it shows that 12.7% husbands and 17.6% wives are thin (wasted, while the

    Tsunamis have inflicted death and destruction on the coastlines of the world throughout history. The occurrence of tsunamis and the resulting effects have been collected and studied as far back as the second millennium B.C. The knowledge gained from cataloging and examining these events has led to significant changes in our understanding of tsunamis, tsunami sources, and methods to mitigate the effects of tsunamis. The most significant, not surprisingly, are often the most devastating, such as the 2011 Tohoku, Japan earthquake and tsunami. The goal of this poster is to give a brief overview of the occurrence of tsunamis and then focus specifically on several significant tsunamis. There are various criteria to determine the most significant tsunamis: the number of deaths, amount of damage, maximum runup height, had a major impact on tsunami science or policy, etc. As a result, descriptions will include some of the most costly (2011 Tohoku, Japan), the most deadly (2004 Sumatra, 1883 Krakatau), and the highest runup ever observed (1958 Lituya Bay, Alaska). The discovery of the Cascadia subduction zone as the source of the 1700 Japanese "Orphan" tsunami and a future tsunami threat to the U.S. northwest coast, contributed to the decision to form the U.S. National Tsunami Hazard Mitigation Program. The great Lisbon earthquake of 1755 marked the beginning of the modern era of seismology. Knowledge gained from the 1964 Alaska earthquake and tsunami helped confirm the theory of plate tectonics. The 1946 Alaska, 1952 Kuril Islands, 1960 Chile, 1964 Alaska, and the 2004 Banda Aceh, tsunamis all resulted in warning centers or systems being established.The data descriptions on this poster were extracted from NOAA's National Geophysical Data Center (NGDC) global historical tsunami database. Additional information about these tsunamis, as well as water level data can be found by accessing the NGDC website www.ngdc.noaa.gov/hazard/

    Identification of motor vehicle crash (MVC) characteristics associated with thoracoabdominal injury would advance the development of automatic crash notification systems (ACNS) by improving triage and response times. Our objective was to determine the relationships between MVC characteristics and thoracoabdominal trauma to develop a torso injury probability model. Drivers involved in crashes from 1993 to 2001 within the National Automotive Sampling System were reviewed. Relationships between torso injury and MVC characteristics were assessed using multivariate logistic regression. Receiver operating characteristic curves were used to compare the model to current ACNS models. There were a total of 56,466 drivers. Age, ejection, braking, avoidance, velocity, restraints, passenger-side impact, rollover, and vehicle weight and type were associated with injury (p < 0.05). The area under the receiver operating characteristic curve (83.9) was significantly greater than current ACNS models. We have developed a thoracoabdominal injury probability model that may improve patient triage when used with ACNS.

  13. Anthropological significance of phenylketonuria.

    1975-01-01

    The highest incidence rates of phenylketonuria (PKU) have been observed in Ireland and Scotlant. Parents heterozygous for PKU in Norway differ significantly from the general population in the Rhesus, Kell and PGM systems. The parents investigated showed an excess of Rh negative, Kell plus and PGM type 1 individuals, which makes them similar to the present populations in Ireland and Scotlant. It is postulated that the heterozygotes for PKU in Norway are descended from a completely assimilated sub-population of Celtic origin, who came or were brought here, 1ooo years ago. Bronze objects of Western European (Scottish, Irish) origin, found in Viking graves widely distributed in Norway, have been taken as evidence of Vikings returning with loot (including a number of Celts) from Western Viking settlements. The continuity of residence since the Viking age in most habitable parts of Norway, and what seems to be a nearly complete regional relationship between the sites where Viking graves contain western imported objects and the birthplaces of grandparents of PKUs identified in Norway, lend further support to the hypothesis that the heterozygotes for PKU in Norway are descended from a completely assimilated subpopulation. The remarkable resemblance between Iceland and Ireland, in respect of several genetic markers (including the Rhesus, PGM and Kell systems), is considered to be an expression of a similar proportion of people of Celtic origin in each of the two countries. Their identical, high incidence rates of PKU are regarded as further evidence of this. The significant decline in the incidence of PKU when one passes from Ireland, Scotland and Iceland, to Denmark and on to Norway and Sweden, is therefore explained as being related to a reduction in the proportion of inhabitants of Celtic extraction in the respective populations.

    Full Text Available The concept of "public accountability" is a challenge for political science as a new concept in this area in full debate and developement ,both in theory and practice. This paper is a theoretical approach of displaying some definitions, relevant meanings and significance odf the concept in political science. The importance of this concept is that although originally it was used as a tool to improve effectiveness and eficiency of public governance, it has gradually become a purpose it itself. "Accountability" has become an image of good governance first in the United States of America then in the European Union.Nevertheless,the concept is vaguely defined and provides ambiguous images of good governance.This paper begins with the presentation of some general meanings of the concept as they emerge from specialized dictionaries and ancyclopaedies and continues with the meanings developed in political science. The concept of "public accontability" is rooted in economics and management literature,becoming increasingly relevant in today's political science both in theory and discourse as well as in practice in formulating and evaluating public policies. A first conclusin that emerges from, the analysis of the evolution of this term is that it requires a conceptual clarification in political science. A clear definition will then enable an appropriate model of proving the system of public accountability in formulating and assessing public policies, in order to implement a system of assessment and monitoring thereof.

    Conflict talks occur in almost every field of human life such as medicine, school, court, and some other social organizations where the interaction results are of much significance to the conversationalists, or in others words, to their status in the organization and honor in the society. A lot of conflicts go unresolved. Oppositional exchanges in a conflict may be used by participants to achieve certain goals, for instance, exploring and developing verbal skills as candidates in a debate competition do, and maintaining social hierarchies within groups or organizations such as leaders giving orders in an institution. Dealing with conflict helps to promote interpersonal relationships.

Meth-ods The data of blood clotting test series(containing PT,PT% ,PTR,INR,Fbg,APTT) for patients after 6 months of mechanical heart valve replacement were collected, then the cases were divided into 4 groups according to their INR levels( group Ⅰ : INR 2.5 ). Results Group Ⅰ contained 28 person-times, with their dosage of warfarin for (3.61 ± 1.44 ) mg, INR 1.38 ± 0. 12, core-bral embolism occurred for 4 person-times,with a inception rate of 14%. Group Ⅱ contained 92 person-times,with their dosage of warfarin for (3.5±1.37)mg,INR 1.65±0. 14,hemorrhinia occurred for 2 person-times,with a in-ception rate of 2%. Group Ⅲ contained 80 person-times, with their dosage of warfarin for (3.18±1.63 )mg, INR 2.23±0.19 ,bematuria occurred for 2 person-times, bemorrhinia occurred for 2 person-times, with a total inception rate of 5% ; Group Ⅳ contained 16 person-times, with their dosage of warfarin for ( 2.32 ± 1. 23 ) mg, INR 2.80± 0.19, hemorrhinia occurred for 2 person-times and hemoptysis occurred for 1 person-times, with a total inception rate of 18.7%. The person-times in group Ⅱ and Ⅲ accounted for 79.6% and the complication rate was the lowest when INR was between 1.5-2.5. Conclusions INR levels between 1.5-2.5 is the most secure, which is the best antico-agu]ation range in our region. Since the anticoagulation strength dynamically changes, the long-term anticoagulation status in patients after mechanical heart valve replacement should be deeply concerned.%目的 了解机械心脏瓣膜置换术后远期国际标准化比值(INR)与并发症的关系,最佳抗凝强度范围及临床意义.方法 对行机械心脏瓣膜置换术后出院6个月以上的患者在门诊检查凝血三项(PT、PT%、PTR、INR、Fbg、APTY)216例

    2015-12-01

    Status epilepticus is a heterogeneous disorder with varied definitions and presentations. Taken together, all forms of status epilepticus carry significant morbidity and mortality, much of which is dictated by the underlying etiology. Generalized convulsive status epilepticus, which represents a common form, is a true neurologic emergency that requires emergent management. Treatment focuses on stabilizing the patient and aggressive medical management to achieve the timely termination of seizures. For other forms of status epilepticus including nonconvulsive and focal status epilepticus, the goal remains early seizure termination, but the use of intravenous medications should be weighed against the risks associated with these therapies. The diagnostic evaluation of status epilepticus is guided by the patient's history and should be broad, including a screen for toxins, electrolytes, structural abnormalities, and central nervous system infectious and autoimmune/inflammatory etiologies. Considerable research is still needed to improve our understanding of the mechanisms, consequences, and therapy of status epilepticus.

    Status Dystonicus is a rare complication of dystonia. It is a life threatening disorder that needs urgent treatment.The aim of this study is to describe clinical features, management and follow up of children with Status Dystonicus. - We conducted a retrospective study over an 8-year period including all patients diagnosed with Status Dystonicus. Clinical characteristics, etiologies and management were analyzed. - Ten patients were included. Main features of Status Dystonicus were a severe generalized dystonia with vegetative signs. Laryngeal spasm and swallowing disorders were observed in 4 cases. Several treatments such as Levodopa, Anticholinergics, Baclofen, Benzodiazepines and Neuroleptics were tried. Mechanical ventilation was required in 4 cases. Two patients died due to rhabdomyolysis and respiratory failure. Others returned to their pre-Status Dystonicus. - Status Dystonicus is a life threatening condition that needs an urgent management on an intensive care unit. In fact, patients with Status Dystonicus can develop respiratory failure and metabolic complications.On the basis of our experience, we delineated a therapeutic approach in which the patient with Status Dystonicus needs supportive care, specific therapy of dystonia and intravenous sedative treatment.

    Full Text Available Background: We and others have shown a significant proportion of interventional trials registered on ClinicalTrials.gov have their primary outcomes altered after the listed study start and completion dates. The objectives of this study were to investigate whether changes made to primary outcomes are associated with the likelihood of reporting a statistically significant primary outcome on ClinicalTrials.gov. Methods: A cross-sectional analysis of all interventional clinical trials registered on ClinicalTrials.gov as of 20 November 2014 was performed. The main outcome was any change made to the initially listed primary outcome and the time of the change in relation to the trial start and end date. Findings: 13,238 completed interventional trials were registered with ClinicalTrials.gov that also had study results posted on the website. 2555 (19.3% had one or more statistically significant primary outcomes. Statistical analysis showed that registration year, funding source and primary outcome change after trial completion were associated with reporting a statistically significant primary outcome. Conclusions: Funding source and primary outcome change after trial completion are associated with a statistically significant primary outcome report on clinicaltrials.gov.

    2007-01-01

    We discuss methods currently in use for determining the significance of peaks in the periodograms of time series. We discuss some general methods for constructing significance tests, false alarm probability functions, and the role played in these by independent random variables and by empirical and theoretical cumulative distribution functions. We also discuss the concept of "independent frequencies" in periodogram analysis. We propose a practical method for estimating the significance of periodogram peaks, applicable to all time series irrespective of the spacing of the data. This method, based on Monte Carlo simulations, produces significance tests that are tailor-made for any given astronomical time series.

  16. Status epilepticus in adults.

    Betjemann, John P; Lowenstein, Daniel H

    2015-06-01

    Status epilepticus is a common neurological emergency with considerable associated health-care costs, morbidity, and mortality. The definition of status epilepticus as a prolonged seizure or a series of seizures with incomplete return to baseline is under reconsideration in an effort to establish a more practical definition to guide management. Clinical research has focused on early seizure termination in the prehospital setting. The approach of early escalation to anaesthetic agents for refractory generalised convulsive status epilepticus, rather than additional trials of second-line anti-epileptic drugs, to avoid neuronal injury and pharmaco-resistance associated with prolonged seizures is gaining momentum. Status epilepticus is also increasingly identified in the inpatient setting as the use of extended electroencephalography monitoring becomes more commonplace. Substantial further research to enable early identification of status epilepticus and efficacy of anti-epileptic drugs will be important to improve outcomes.

  17. Significant Scales in Community Structure

    Traag, V A; Van Dooren, P

    2013-01-01

    Many complex networks show signs of modular structure, uncovered by community detection. Although many methods succeed in revealing various partitions, it remains difficult to detect at what scale some partition is significant. This problem shows foremost in multi-resolution methods. We here introduce an efficient method for scanning for resolutions in one such method. Additionally, we introduce the notion of "significance" of a partition, based on subgraph probabilities. Significance is independent of the exact method used, so could also be applied in other methods, and can be interpreted as the gain in encoding a graph by making use of a partition. Using significance, we can determine "good" resolution parameters, which we demonstrate on benchmark networks. Moreover, optimizing significance itself also shows excellent performance. We demonstrate our method on voting data from the European Parliament. Our analysis suggests the European Parliament has become increasingly ideologically divided and that nationa...

    Smoking is a major risk factor for the development of heart failure (HF). Yet, little is known about smoking\\'s effects on the health status of established HF patients. HF patients were recruited from outpatient clinics across North America. The Kansas City Cardiomyopathy Questionnaire (KCCQ) was used to assess disease-specific health status. Smoking behaviors were classified as never having smoked, prior smoker, and as having smoked within the past 30 days. Risk-adjusted multivariable regression was used to evaluate the association of smoking status with baseline and 1-year KCCQ overall summary scores. Smoking was not associated with baseline health status. However, a significant effect was observed on 1-year health status among outpatients with HF with current smokers reporting significantly lower KCCQ scores than never smokers or ex-smokers. These findings highlight an additional adverse consequence of smoking in HF patients not previously discussed.

    目的:探讨紧密连接蛋白(ZO-1)基因启动子区甲基化状态在儿童非霍奇金淋巴瘤(NHL)Ⅳ期检测中的临床意义,以进一步寻找病因及早期诊断方法。方法将55例确诊为NHLⅣ期(T细胞型40例, B细胞型15例)患儿的骨髓标本作为病例组,20例非血液肿瘤患儿骨髓标本作为对照组。采用甲基化特异性PCR法(MS-PCR)检测病例组与对照组骨髓中ZO-1基因启动子区甲基化状态,并检测光密度积分值(IOD)。逆转录PCR法(RT-PCR)检测病例组与对照组ZO-1基因mRNA的表达情况。结果 MS-PCR检测结果显示病例组治疗前39例出现ZO-1基因甲基化条带,阳性率为70.9%(39/55),对照组20例均呈非甲基化状态;治疗过程中,行动态观察NHL患儿47例,其中T细胞型32例,B细胞型15例,治疗前ZO-1基因甲基化阳性率分别为72%和67%,两者差异无统计学意义(P>0.05)。T细胞型与B细胞型NHL患儿治疗前与化疗早期、中期比较差异均无统计学意义(P>0.05),而与化疗后期比较差异均有统计学意义(P0.572). The cases of T-NHL and B-NHL showed no signiifcant changes in methylation rate in the early and middle phases of chemotherapy (P>0.05), but they showed signiifcant changes in methylation rate in the late phase of chemotherapy (P<0.05). RT-PCR showed that the NHL cases carrying methylated ZO-1 gene had no mRNA expression of ZO-1, while all children in the control group had mRNA expression of ZO-1. There was no linear relationship between the total number of peripheral blood leukocytes and ZO-1 gene IOD (r=0.093, P=0.575);a positive correlation was found between the number of malignant cells in bone marrow and ZO-1 gene IOD (r=0.669, P<0.001). Conclusions ZO-1 gene shows a hypermethylation status in children with NHL, and the methylation level is positively correlated with the number of malignant cells in bone marrow. ZO-1 may be used as a novel

  4. Significance analysis of prognostic signatures.

    Directory of Open Access Journals (Sweden)

    Andrew H Beck

    Full Text Available A major goal in translational cancer research is to identify biological signatures driving cancer progression and metastasis. A common technique applied in genomics research is to cluster patients using gene expression data from a candidate prognostic gene set, and if the resulting clusters show statistically significant outcome stratification, to associate the gene set with prognosis, suggesting its biological and clinical importance. Recent work has questioned the validity of this approach by showing in several breast cancer data sets that "random" gene sets tend to cluster patients into prognostically variable subgroups. This work suggests that new rigorous statistical methods are needed to identify biologically informative prognostic gene sets. To address this problem, we developed Significance Analysis of Prognostic Signatures (SAPS which integrates standard prognostic tests with a new prognostic significance test based on stratifying patients into prognostic subtypes with random gene sets. SAPS ensures that a significant gene set is not only able to stratify patients into prognostically variable groups, but is also enriched for genes showing strong univariate associations with patient prognosis, and performs significantly better than random gene sets. We use SAPS to perform a large meta-analysis (the largest completed to date of prognostic pathways in breast and ovarian cancer and their molecular subtypes. Our analyses show that only a small subset of the gene sets found statistically significant using standard measures achieve significance by SAPS. We identify new prognostic signatures in breast and ovarian cancer and their corresponding molecular subtypes, and we show that prognostic signatures in ER negative breast cancer are more similar to prognostic signatures in ovarian cancer than to prognostic signatures in ER positive breast cancer. SAPS is a powerful new method for deriving robust prognostic biological signatures from clinically

    1984-03-01

    The Pacific Northwest Laboratory has studied the safety aspects of monitoring the preoperational status of safety systems in nuclear power plants. The goals of the study were to assess for the NRC the effectiveness of current monitoring systems and procedures, to develop near-term guidelines for reducing human errors associated with monitoring safety system status, and to recommend a regulatory position on this issue. A review of safety system status monitoring practices indicated that current systems and procedures do not adequately aid control room operators in monitoring safety system status. This is true even of some systems and procedures installed to meet existing regulatory guidelines (Regulatory Guide 1.47). In consequence, this report suggests acceptance criteria for meeting the functional requirements of an adequate system for monitoring safety system status. Also suggested are near-term guidelines that could reduce the likelihood of human errors in specific, high-priority status monitoring tasks. It is recommended that (1) Regulatory Guide 1.47 be revised to address these acceptance criteria, and (2) the revised Regulatory Guide 1.47 be applied to all plants, including those built since the issuance of the original Regulatory Guide.

    Full Text Available The study aims to determine fertility status of the soil after organic paddy experiments using kinds and doses of organic fertilizers. Experiment was conducted at greenhouse laboratory in Faculty of Agriculture Sebelas Maret University Surakarta. Experimental design used completely randomized design with 9 kinds of treatment was replicated 3 times. Experiments were the use of cow manure, Azolla fertilizer, Azolla inoculum and its combinations that are based on fulfilling nutrient requirements of 120 kg N ha-1. Result shows that the use of cow manure, Azolla fertilizers and Azolla inoculum had no effect on changes of soil fertility status. Soil fertility status was not significantly correlated with cow manure (0,16ns, Azolla fertilizer (0,26ns and Azolla inoculum (0,16ns. Average of final soil fertility status included fertile category, which was similar as the initial soil fertility status. Average of final soil properties of treatment but nevertheless was relatively higher than in no treatment, indicating the use of cow manure, Azolla fertilizer, Azolla inoculum and its combinations had greater impact to soil properties. Cow manure despite increased available K2O and dry grain, but it did not significantly increase the soil fertility status from fertile to very fertile. This was presumably due to the relatively short experiment period, only one planting season had not given significant effect to soil properties. Implication of this study is the use of cow manure, Azolla fertilizer, Azolla inoculum and its combinations although did not increase the soil fertility status but could maintain soil fertility status as the initial conditions before planting.

    The four topics are described including the driving force and source of the scientific and technological creation, the definition and history of the bionics, the important significance of bionics in the development of the human beings, and the leading edge and progress of bionics. The appetency of human for the creation is the essential motivity of the innovation in science and technology. Nature and society are the objects for us to cognize and serve, meanwhile, the best teachers for us to learn from them. It is only 5 million years for human's development, but evolution of life has over 3.5 billion years history. Although, copying the creation from the human being is important, however, it has much more potential and opportunity in imitating the nature, and more possibility to promote the ability of original innovation. The significance and progress of bionics are summarized, in this paper, and the leading edges of bionics, in the near future, are forecasted.

    We used logistic regression on nationally representative data (General Social Survey, N = 10,668 and N = 6680) to examine how sexual minority status related to happiness. We considered two central dimensions of sexual minority status-sexual behavior and sexual identity. We distinguished between same-sex, both-sex, and different-sex-oriented participants. Because individuals transition between sexual behavior categories over the life course (e.g., from both-sex partners to only same-sex partners) and changes in sexual minority status have theoretical associations with well-being, we also tested the associations of transitions with happiness. Results showed that identifying as bisexual, gay, or lesbian, having both male and female partners since age 18, or transitioning to only different-sex partners was negatively related to happiness. Those with only same-sex partners since age 18 or in the past 5 years had similar levels of happiness as those with only different-sex partners since age 18. Additional tests showed that the majority of these happiness differences became non-significant when economic and social resources were included, indicating that the lower happiness was a product of structural and societal forces. Our findings clearly and robustly underscored the importance of taking a multi-faceted approach to understanding sexuality and well-being, demonstrating that not all sexual minority groups experience disadvantaged happiness. Our study calls for more attention to positive aspects of well-being such as happiness in examinations of sexual minorities and suggests that positive psychology and other happiness subfields should consider the role of sexual minority status in shaping happiness.

    Status epilepticus (SE) is a medical emergency for companion animals, with significant associated morbidity and mortality. Therapy in companion animals and people has been largely with sedatives and anesthetics, many of which have gamma-aminobutyric acid receptor-mediated mechanisms. Early aggressive treatment includes staged first-line therapy with benzodiazepines, and second- and third-line protocols when needed. Recently, intravenous levetiracetam has also been used in for SE in dogs and people, and there are other human intravenous drug preparations that may hold promise for future use in companion animals.

    Background Convulsive status epilepticus often results in permanent neurologic impairment. We evaluated the effect of induced hypothermia on neurologic outcomes in patients with convulsive status epilepticus. Methods In a multicenter trial, we randomly assigned 270 critically ill patients with convulsive status epilepticus who were receiving mechanical ventilation to hypothermia (32 to 34°C for 24 hours) in addition to standard care or to standard care alone; 268 patients were included in the analysis. The primary outcome was a good functional outcome at 90 days, defined as a Glasgow Outcome Scale (GOS) score of 5 (range, 1 to 5, with 1 representing death and 5 representing no or minimal neurologic deficit). The main secondary outcomes were mortality at 90 days, progression to electroencephalographically (EEG) confirmed status epilepticus, refractory status epilepticus on day 1, "super-refractory" status epilepticus (resistant to general anesthesia), and functional sequelae on day 90. Results A GOS score of 5 occurred in 67 of 138 patients (49%) in the hypothermia group and in 56 of 130 (43%) in the control group (adjusted common odds ratio, 1.22; 95% confidence interval [CI], 0.75 to 1.99; P=0.43). The rate of progression to EEG-confirmed status epilepticus on the first day was lower in the hypothermia group than in the control group (11% vs. 22%; odds ratio, 0.40; 95% CI, 0.20 to 0.79; P=0.009), but there were no significant differences between groups in the other secondary outcomes. Adverse events were more frequent in the hypothermia group than in the control group. Conclusions In this trial, induced hypothermia added to standard care was not associated with significantly better 90-day outcomes than standard care alone in patients with convulsive status epilepticus.

    Full Text Available Refractory status epilepticus is a potentially life-threatening medical emergency. It requires early diagnosis and treatment. There is a lack of consensus upon its semantic definition of whether it is status epilepticus that continues despite treatment with benzodiazepine and one antiepileptic medication (AED, i.e., Lorazepam + phenytoin. Others regard refractory status epilepticus as failure of benzodiazepine and 2 antiepileptic medications, i.e., Lorazepam + phenytoin + phenobarb. Up to 30% patients in SE fail to respond to two antiepileptic drugs (AEDs and 15% continue to have seizure activity despite use of three drugs. Mechanisms that have made the treatment even more challenging are GABA-R that is internalized during status epilepticus and upregulation of multidrug transporter proteins. All patients of refractory status epilepticus require continuous EEG monitoring. There are three main agents used in the treatment of RSE. These include pentobarbital or thiopental, midazolam and propofol. RSE was shown to result in mortality in 35% cases, 39.13% of patients were left with severe neurological deficits, while another 13% had mild neurological deficits.

    Full Text Available Keadaan gizi golongan rawan khususnya anak batita (bawah tiga tahun dapat dipakai sebagai petunjuk keadaan gizi masyarakat. Penentuan status gizi biasanya dilakukan atas dasar pengukuran berat dan tinggi badan dengan menggunakan indeks berat menurut umur, berat menurut tinggi badan atau tinggi menurut umur. Prevalensi kurang gizi yang tinggi pada anak Batita menjadi petunjuk bahwa status gizi masyarakat tersebut masih rendah. Banyak faktor yang diduga mempengaruhi status gizi pada Batita, seperti faktor sosial, lingkungan dan penyakit infeksi. Untuk mengetahui seberapa jauh peran dari faktor-faktor tersebut di atas, dilakukan analisis data ini dengan menggunakan indeks anthropometri berat badan menurut umur.Sumber data yang digunakan adalah hasil Survei Kesejahteraan Keluarga Indonesia 1992 (IFLS. Penelitian ini bersifat cros sectional dan dilakukan di tujuh propinsi di Indonesia. Sebagai unit analisis adalah anak Batita (umur 1-3 tahun, dengan jumlah 1540 populasi.Hasil penelitian menunjukkan ada beberapa faktor yang berperan dalam status gizi anak antara lain adalah urutan kelahiran, pendidikan ibu, diare, panas dan jumlah anggota rumah tangga. Pola makan tidak mempengaruhi status gizi anak laki-laki ataupun anak perempuan. Besarnya anggota rumah tangga walaupun pada analisis bivariat memberikan pengaruh yang bermakna namun pada analisis multivariat tidak memberikan pengaruh yang bermakna, baik pada anak laki-laki ataupun perempuan. pada analisis multivariat untuk anak laki-laki hanya variabel unrutan kelahiran dan pendidikan ibu yang menunjukkan risiko yang bermakna. Sedangkan pada anak perempuan terdapat tiga variabel yang memberikan risiko yang bermakna yaitu urutan keluarga, diare dan panas.

  10. Robust Simulations and Significant Separations

    CERN Document Server

    Fortnow, Lance

    2010-01-01

    We define and study a new notion of "robust simulations" between complexity classes which is intermediate between the traditional notions of infinitely-often and almost-everywhere, as well as a corresponding notion of "significant separations". A language L has a robust simulation in a complexity class C if there is a language in C which agrees with L on arbitrarily large polynomial stretches of input lengths. There is a significant separation of L from C if there is no robust simulation of L in C. The new notion of simulation is a cleaner and more natural notion of simulation than the infinitely-often notion. We show that various implications in complexity theory such as the collapse of PH if NP = P and the Karp-Lipton theorem have analogues for robust simulations. We then use these results to prove that most known separations in complexity theory, such as hierarchy theorems, fixed polynomial circuit lower bounds, time-space tradeoffs, and the theorems of Allender and Williams, can be strengthened to signifi...

  11. Significance of biofilms in dentistry.

    Wróblewska, Marta; Strużycka, Izabela; Mierzwińska-Nastalska, Elżbieta

    2015-01-01

    In the past decades significant scientific progress has taken place in the knowledge about biofilms. They constitute multilayer conglomerates of bacteria and fungi, surrounded by carbohydrates which they produce, as well as substances derived from saliva and gingival fluid. Modern techniques showed significant diversity of the biofilm environment and a system of microbial communication (quorum sensing), enhancing their survival. At present it is believed that the majority of infections, particularly chronic with exacerbations, are a result of biofilm formation, particularly in the presence of biomaterials. It should be emphasised that penetration of antibiotics and other antimicrobial agents into deeper layers of a biofilm is poor, causing therapeutic problems and necessitating sometimes removal of the implant or prosthesis. Biofilms play an increasing role in dentistry as a result of more and more broad use in dental practice of plastic and implantable materials. Biofilms are produced on the surfaces of teeth as dental plaque, in the para-nasal sinuses, on prostheses, dental implants, as well as in waterlines of a dental unit, constituting a particular risk for severely immunocompromised patients. New methods of therapy and prevention of infections linked to biofilms are under development.

    Full Text Available This article addresses the question of the meaning and legal significance of constitutional values in contemporary times. The article attends also to related questions namely, what constitute “constitutional values” and what are the limitations of the meaning afforded to this notion. Attention is paid in the particular, to freedom, equality and democracy as value-neutral criteria of fairness and government neutrality with reference to the South African and German contexts as well as to value-neutrality as a culturally conditioned value. The author concludes with a cosmopolitan view of freedom and the right to peace with reference to the constitutional texts of Japan and the United States.

  13. The significance of small streams

    Science.gov (United States)

    Wohl, Ellen

    2017-09-01

    Headwaters, defined here as first- and secondorder streams, make up 70%‒80% of the total channel length of river networks. These small streams exert a critical influence on downstream portions of the river network by: retaining or transmitting sediment and nutrients; providing habitat and refuge for diverse aquatic and riparian organisms; creating migration corridors; and governing connectivity at the watershed-scale. The upstream-most extent of the channel network and the longitudinal continuity and lateral extent of headwaters can be difficult to delineate, however, and people are less likely to recognize the importance of headwaters relative to other portions of a river network. Consequently, headwaters commonly lack the legal protections accorded to other portions of a river network and are more likely to be significantly altered or completely obliterated by land use.

    2013-09-01

    Hypertriglyceridemia is a common lipid disorder as well as hypercholesterolemia. However clinical significance of hypertriglyceridemia is not fully understood because of its heterogeneous lipoprotein phenotypes and complex etiology. Severe hypertriglyceridemia increases the risk for pancreatitis, whereas mild or moderate hypertriglyceridemia may be a risk factor for cardiovascular disease. Patients with hypertriglyceridemia are usually accompanied by other cardiovascular related disorders, such as central obesity, type 2 diabetes, and liver steatosis. Ectopic fat accumulation is often seen in hypertriglyceridemic subjects and various organ injuries are developed by the lipotoxicity. Hypertriglyceridemia is strongly associated with remnant lipoprotein accumulation, increased small dense LDL, and low HDL-cholesterol. All these lipid abnormalities are recognized as cardiovascular risk factors. The pathophysiology of lipoprotein metabolism related to the hypertriglyceridemia is summarized in this brief review.

    After practical changes were approved to the initial conceptual design of the cryogenic system for MSU FRIB and an agreement was made with JLab in 2012 to lead the design effort of the cryogenic plant, many activities are in place leading toward a cool-down of the linacs prior to 2018. This is mostly due to using similar equipment used at CHLII for the 12 GeV upgrade at JLab and an aggressive schedule maintained by the MSU Conventional Facilities department. Reported here is an updated status of the cryogenic plant, including the equipment procurement status, plant layout, facility equipment and project schedule.

  19. Correlation of sense of coherence with oral health behaviors, socioeconomic status, and periodontal status

    Directory of Open Access Journals (Sweden)

    Kommuri Sahithi Reddy

    2016-01-01

    Full Text Available Introduction: The sense of coherence (SOC has been suggested to be highly applicable concept in the public health area because a strong SOC is stated to decrease the likelihood of perceiving the social environment as stressful. This reduces the susceptibility to the health-damaging effect of chronic stress by lowering the likelihood of repeated negative emotions to stress perception. Materials and Methods: The demographic data and general information of subjects' oral health behaviors such as frequency of cleaning teeth, aids used to clean teeth, and dental attendance were recorded in the self-administered questionnaire. The SOC-related data were obtained using the short version of Antonovsky's SOC scale. The periodontal status was recorded based on the modified World Health Organization 1997 pro forma. Results: The total of 780 respondents comprising 269 (34.5% males and 511 (65.5% females participated in the study. A significant difference was noted among the subjects for socioeconomic status based on gender (P = 0.000. The healthy periodontal status (community periodontal index [CPI] code 0 was observed for 67 (24.9% males and 118 (23.1% females. The overall SOC showed statistically negative correlation with socioeconomic status scale (r = −0.287. The CPI and loss of attachment (periodontal status were significantly and negatively correlated with SOC. Conclusion: The present study concluded that a high level of SOC was associated with good oral health behaviors, periodontal status, and socioeconomic status.

    Full Text Available The objective of this study was to compare the periodontal status in postmenopausal women with osteopenia and osteoporosis. Material and Methods: We examined 43 postmenopausal women aged from 55 to 74 years. Material assessment of bones in every patient was performed by means of dual energy X-ray absorptiometry (DXA from two points on the skeleton – part of the femur neck and between the first and fourth lumbar vertebrae. A lipid blood test was done for patients of both groups. All patients were divided into two groups (the 1st with osteopenia, and the 2nd with osteoporosis. All patients were subjected to an oral clinical examination: the periodontal examination was composed of Plaque Index (PI, Pocket Score (PS, and Papillary Bleeding Index (PBI. X-ray analysis was performed for every patient. Results: The results of the clinical periodontal examination demonstrated that the mean PBI in patients in the 1st group had no significant differences from the PBI in patients in the 2nd group. PI value and PS findings in patients with general osteoporosis also had no statistical differences from the same parameters in patients with osteopenia. Conclusion: Under the circumstances of these patients’ characteristics and within the limits of the present study, we concluded that there is no significant difference in the periodontal status of postmenopausal women with systemic osteopenia and with osteoporosis.

    This report summarizes the work performed under the project (3z(BStatitically significant relational data mining.(3y (BThe goal of the project was to add more statistical rigor to the fairly ad hoc area of data mining on graphs. Our goal was to develop better algorithms and better ways to evaluate algorithm quality. We concetrated on algorithms for community detection, approximate pattern matching, and graph similarity measures. Approximate pattern matching involves finding an instance of a relatively small pattern, expressed with tolerance, in a large graph of data observed with uncertainty. This report gathers the abstracts and references for the eight refereed publications that have appeared as part of this work. We then archive three pieces of research that have not yet been published. The first is theoretical and experimental evidence that a popular statistical measure for comparison of community assignments favors over-resolved communities over approximations to a ground truth. The second are statistically motivated methods for measuring the quality of an approximate match of a small pattern in a large graph. The third is a new probabilistic random graph model. Statisticians favor these models for graph analysis. The new local structure graph model overcomes some of the issues with popular models such as exponential random graph models and latent variable models.

  2. Determining Semantically Related Significant Genes.

    Taha, Kamal

    2014-01-01

    GO relation embodies some aspects of existence dependency. If GO term xis existence-dependent on GO term y, the presence of y implies the presence of x. Therefore, the genes annotated with the function of the GO term y are usually functionally and semantically related to the genes annotated with the function of the GO term x. A large number of gene set enrichment analysis methods have been developed in recent years for analyzing gene sets enrichment. However, most of these methods overlook the structural dependencies between GO terms in GO graph by not considering the concept of existence dependency. We propose in this paper a biological search engine called RSGSearch that identifies enriched sets of genes annotated with different functions using the concept of existence dependency. We observe that GO term xcannot be existence-dependent on GO term y, if x- and y- have the same specificity (biological characteristics). After encoding into a numeric format the contributions of GO terms annotating target genes to the semantics of their lowest common ancestors (LCAs), RSGSearch uses microarray experiment to identify the most significant LCA that annotates the result genes. We evaluated RSGSearch experimentally and compared it with five gene set enrichment systems. Results showed marked improvement.

    Full Text Available Abstract Background Having a significant other has been shown to be protective against physical and psychological health conditions for adults. Less is known about the period of emerging young adulthood and associations between significant others’ weight and weight-related health behaviors (e.g. healthy dietary intake, the frequency of physical activity, weight status. This study examined the association between significant others’ health attitudes and behaviors regarding eating and physical activity and young adults’ weight status, dietary intake, and physical activity. Methods This study uses data from Project EAT-III, a population-based cohort study with emerging young adults from diverse ethnic and socioeconomic backgrounds (n = 1212. Logistic regression models examining cross-sectional associations, adjusted for sociodemographics and health behaviors five years earlier, were used to estimate predicted probabilities and calculate prevalence differences. Results Young adult women whose significant others had health promoting attitudes/behaviors were significantly less likely to be overweight/obese and were more likely to eat ≥ 5 fruits/vegetables per day and engage in ≥ 3.5 hours/week of physical activity, compared to women whose significant others did not have health promoting behaviors/attitudes. Young adult men whose significant other had health promoting behaviors/attitudes were more likely to engage in ≥ 3.5 hours/week of physical activity compared to men whose significant others did not have health promoting behaviors/attitudes. Conclusions Findings suggest the protective nature of the significant other with regard to weight-related health behaviors of young adults, particularly for young adult women. Obesity prevention efforts should consider the importance of including the significant other in intervention efforts with young adult women and potentially men.

    Full Text Available Ninety infants were selected stratified proportionally random sampling and they met the inclusion criteria. Iron status was determined by the serum ferritin level concentration. The nutritional status was determined by the body weight to age based on the standard criteria of WHO NCHS. The quality of food was defined by asking the parents to keep a diary of consumed in the last 7 days minimally for three days. Out of the 90 infants, 50.4 % of them were males and 45.6 % of them were females. Most of them (93.7% had normal nourished and 8.3 % had undernourished. The prevalence status of low iron was 18.9%. The low iron status began to occur at the age of 4 – 6 months old (6% and the highest at the age of 9 – 12 months old (65%. Statistically significant differences were found between the iron status and the quality of food supplements over age group. The low quality of food is a risk factor influence the status of low iron. It is suggested that the iron supplements be given to breast-fed infant at the age of 4 – 6 months old.

    The purpose of this study was to explore relationships between functional status after childbirth and related concepts. The sample consisted of 177 women. The Personal Resource Questionnaire (PRQ) 85-Part 2, the State Trait Anxiety Inventory (STAI), and the Inventory of Functional Status After Childbirth (IFSAC) were used to measure variables. Data were collected during the third trimester of pregnancy and at 6 weeks postpartum. Overall, this group had relatively low levels of anxiety and high levels of social support and functional status after childbirth. The STAI demonstrated coefficient alphas from .90 to .93, the PRQ 85-Part 2 .87 to .93, and the IFSAC .90. The relationship between state anxiety in the postpartum period and FSAC (r = -.204, p = .008) was significant. Additional significant findings between social support, anxiety, and subscales of the IFSAC were found. Nurses must understand these relationships to develop and implement effective interventions. This study is clinically relevant to nurses involved in caring for pregnant and postpartum clients.

    Full Text Available Social hierarchy is a fact of life for many animals. Navigating social hierarchy requires understanding one's own status relative to others and behaving accordingly, while achieving higher status may call upon cunning and strategic thinking. The neural mechanisms mediating social status have become increasingly well understood in invertebrates and model organisms like fish and mice but until recently have remained more opaque in humans and other primates. In a new study in this issue, Noonan and colleagues explore the neural correlates of social rank in macaques. Using both structural and functional brain imaging, they found neural changes associated with individual monkeys' social status, including alterations in the amygdala, hypothalamus, and brainstem--areas previously implicated in dominance-related behavior in other vertebrates. A separate but related network in the temporal and prefrontal cortex appears to mediate more cognitive aspects of strategic social behavior. These findings begin to delineate the neural circuits that enable us to navigate our own social worlds. A major remaining challenge is identifying how these networks contribute functionally to our social lives, which may open new avenues for developing innovative treatments for social disorders.

    Traditional Chinese Medicine(TCM), based on the philosophic idea of “correlation between man and nature” and “balance of Yin and Yang” and characterized by “integrated concept” and “syndrome identification & treatment determination”, adjusts and activates the self-recuperating ability to rectify its differentiation from normality of human body to meet the goal of preventing and treating diseases mainly by means of traditional Chinese medicinal herbs, acupuncture and moxibustion, etc. The idea of “Human should be in harmony with Nature including bacterium, virus, etc., but not to extemainate microbe in a large scale”, held and promoted by TCM gives, rise to a delicate physiological equilibrium kept between man and microbe and this is just the development trend of medical science in future. For thousands years, TCM has made indelible contribution to the reproduction and prosperity of the Chinese nation, and under the countless attacks of pestilence has never made its people's death in millions, not such as once occurred in Europe. TCM is also characterized by its “simple, convenient, cheap and effective” method of treatment and is especially good at preventing and treating chronic diseases,complicate multi-system diseases and new-type virus diseases. Therefore, only when the sanitation and healthcare system is established can the health of 1.3 billion people in China and the problem of shoaage of doctor and medicine for 900 million rural population and large number of poverty-stricken urban population be solved. It is strongly suggested that five promotion projects, namely: TCM policy and statute guarantee, TCM qualified personnel cultivation, TCM scientific research, development of TCM in rural areas and TCM administrative system reform should be carried out in real earnest to make TCM develop in a sustainable way.

    Full Text Available El crecimiento y el desarrollo constituyen dos procesos orgánicos fisiológicos por los que los seres vivos incrementan su masa y maduran morfológicamente, y por ello, adquieren una plena capacidad funcional. Si se tiene en cuenta que el crecimiento en la especie humana muestra un ritmo discontinuo, esto es, alternancia de períodos de crecimiento rápido o fases de aceleración con fases de desaceleración, su estudio entre la población pediátrica resultará complejo y se hace necesario el uso de modelos matemáticos y estándares de referencia. El objetivo de este trabajo ha sido llevar a cabo una revisión acerca de los principales modelos o métodos existentes para analizar la curva de crecimiento durante la edad pediátrica, así como los estándares de referencia más importantes y los parámetros de evaluación del crecimiento.

    Full Text Available Background: Atlas is the first cervical vertebra. Sometimes there is partial or complete fusion of atlas with basal part of the occipital bone known as assimilation of atlas or atlanto-occipital fusion. It is normally congenital. It may be associated with the constriction of foramen magnum which may compress the spinal cord or brain stem. Methods: The 1000 human dry skulls were selected from the anthropology museum of department of anatomy, GSVM medical college, Kanpur. The age and sex of the skulls were not taken into consideration. The skulls were examined for the bony union between the atlas and skull and other variations in assimilated atlas. Results: Fused atlas with skull was seen in 20 skulls (2.0%. Partial fusion of anterior arch of atlas with the occipital bone was seen in 1 specimen (5% and in 10% it was found complete fusion. In 10% skulls the posterior arch fused with the occipital bone. Bilateral fusion of transverse process with occipital bone was noted in 2 (10% specimen. The incomplete foramen transversarium was found in 1 skull (5% {bilateral} and in 2 skulls (10%, the transverse process was noted without the foramen transversarium {bilateral}. Conclusion: Out of 1000 examined skulls, fusion of atlas with the occipital bone was noted in 20 skulls (2%. The knowledge of incidence of assimilation of atlas and its variations may be helpful for the embryologist, neurosurgeons and orthopedic surgeons. [Int J Res Med Sci 2015; 3(2.000: 420-424

  4. Noblesse oblige? Social status and economic inequality maintenance among politicians.

    Economic inequality is at historically high levels in the United States and is among the most pressing issues facing society. And yet, predicting the behavior of politicians with respect to their support of economic inequality remains a significant challenge. Given that high status individuals tend to conceive of the current structure of society as fair and just, we expected that high status members of the U.S. House of Representatives would be more likely to support economic inequality in their legislative behavior than would their low status counterparts. Results supported this prediction particularly among Democratic members of Congress: Whereas Republicans tended to support legislation increasing economic inequality regardless of their social status, the social status of Democrats - measured in terms of average wealth, race, or gender - was a significant predictor of support for economic inequality. Policy implications of the observed relationship between social status and support for economic inequality are considered.

  5. Astrobiological Significance of Microbial Extremophiles

    The microflora of the cryosphere of planet Earth provides the best analogs for life forms that might be found in the permafrost or polar ice caps of Mars, near the surface of the cometary nuclei, or in the liquid water beneath and the ice crusts of icy moons of Jupiter and Saturn. The importance of study alkaliphilic microorganisms for astrobiology was enhanced by the findings of abundant carbonates and carbonate globules rimmed with possibly biogenic magnetites in association with the putative microfossils in the ALH84001 meteorite. Although the ALH84001 "nanofossils" were to small and simple to be unambiguously recognized as biogenic, they stimulated Astrobiology research and studies of microbial extremophiles and biomarkers in ancient rocks and meteorites. Recent studies of CI and CM carbonaceous meteorites have resulted in the detection of the well-preserved mineralized remains of coccoidal and filamentous microorganisms in cyanobacterial mats. Energy Dispersive X-ray Analysis has shown anomalous biogenic element ratios clearly indicating they are not recent biological contaminants. This paper reviews microbial extremophiles in context of their significance to Astrobiology. The study of halophilic microorganisms was started from work with saline soils and lakes, and one of the record of good growth for Haloferax mediterranei was shown at 30 percent NaC1. Although alkali-tolerant nitrifying bacteria had previously been reported, the first described alkaliphilic microorganism was the bacterium Streptococcus faecalis. Halophilic and alkaliphilic forms are relevant to conditions that might be found in closed impact basins and craters on Mars filled with evaporite deposits. The first obligately acidophilic bacterium described was Acidithiobacillus ferrooxydans (formally Thiobacillus ferrooxidans). Later thermophilic lithotrophic acidophiles were found, and the hyperacidophilic moderately thermophilic species of the genus Picrophilus were found to grow at negative p

    Recently, we encountered 2 cases of diffuse iron deposition in gastric antral and fundic glandular epithelium, which in 1 patient eventually led to the diagnosis of hemochromatosis. Gastric mucosal siderosis (GS) has previously been described in hemochromatosis patients, alcoholics, and in association with iron medications. However, the prevalence of various patterns of iron deposition in the gastric mucosa and their clinical significance have not been studied in detail. The 2 index cases mentioned above and 500 additional consecutive gastric biopsies examined over a period of 8 months at our institution were stained for iron by the Prussian blue method. In addition, all patients with genetic hemochromatosis diagnosed by liver biopsy in our department between 1998 and 2003 who also had gastric biopsies were identified from the surgical pathology files and included in the study (n = 3). The location of iron deposition [stromal cells (endothelium, fibroblasts, macrophages), glandular epithelium, or extracellular] was recorded and subjectively graded as 1+ to 3+ according to the severity of deposition within the mucosa. Relevant histologic changes (inflammation, presence of H. pylori, ulceration) and clinical features were reviewed. Three patterns of GS were identified: A) "nonspecific GS" with predominant iron deposition in the stromal cells including macrophages, and focally in epithelium; B) "iron-pill gastritis" with often mild gastritis and reactive gastropathy type changes, and mostly extracellular deposition with focal stromal cells and epithelial deposition; and C) predominant deposition in antral and fundic glandular epithelium. Of the 500 cases studied, a total of 18 (3.6%) cases were found to have GS. Of these 18 cases, 11 (2.2%) showed pattern A, 4 (0.8%) showed pattern B, and 3 (0.6%) showed pattern C. The GS in patterns A and B was always focal or patchy (1+ to 2+), whereas in pattern C it was generally diffuse and strong (2+ to 3+). A history of oral

    A 72-year-old woman presented with first onset of seizure with no prior history of cognitive dysfunction. EEG revealed focal non-convulsive status epilepticus. MRI brain showed a left temporal non-enhancing lesion. Temporal pole biopsy showed acute neuronal necrosis and astrocyte hyperplasia together with extensive amyloid plaques and neurofibrillary tangles. Perivascular oligodendroglial hyperplasia was present. Postmortem examination revealed extensive plaque and tangle disease. Perivascular oligodendroglial hyperplasia was limited to the left temporal area. The presence of focal perivascular oligodendroglial hyperplasia in the left temporal cortex, combined with extensive plaque and tangle disease may have contributed to the focal status epilepticus in this patient. Although the presence of focal perivascular oligodendroglial hyperplasia has been reported in cases of temporal lobe epilepsy, it has not been reported as a cause of seizure in patients with Alzheimer\\'s disease previously. Further studies for clinical-pathologic correlation would be required to confirm this hypothesis.

    In addition to its medical importance as parasitic pathogen, Entamoeba has aroused people's interest in its evolutionary status for a long time. Lacking mitochondrion and other intracellular organelles common to typical eukaryotes, Entamoeba and several other amitochondrial protozoans have been recognized as ancient pre-mitochondriate eukaryotes and named "archezoa", the most primitive extant eukaryotes. It was suggested that they might be living fossils that remained in a primitive stage of evolution before acquisition of organelles, lying close to the transition between prokaryotes and eukaryotes. However, recent studies revealed that Entamoeba contained an organelle, "crypton" or "mitosome", which was regarded as specialized or reductive mitochondrion. Relative molecular phylogenetic analyses also indicated the existence or the probable existence of mitochondrion in Entamoeba. Our phylogenetic analysis based on DNA topoisomerase II strongly suggested its divergence after some mitchondriate eukaryotes. Here, all these recent researches are reviewed and the evolutionary status of Entamoeba is discussed.

    This article presents and discusses findings on the health status of newcomers residing in Windsor, Ontario. The data are part of a larger study, which was based on the Ontario Health Survey's questionnaire. Data were collected from 548 newcomers through home visits, focus groups, mail surveys, and telephone interviews. Descriptive multivariate analyses focused on main areas in newcomers' physical and mental health status and their access to health services. The findings identified that most newcomers do not have acute, life-threatening physical problems or chronic illness. They do not experience major problems with access to health care or activity limitations. Men are happier, more satisfied with their health, and less stressed than women. This study has implications for adoption of sensitive transcultural approaches to promote newcomers' health. Special challenges lie in women's health and mental health.

    Full Text Available Background: Central Bureau of Statistics data in 2006, showed that the average life expectancy of the population living in Yogyakarta (DIY was 73 years, and 73.8 years for those living in Sleman. This was higher than the average national life expectancy of 68.5 years. National Health Survey in 2007 showed that the prevalence of oral and dental problems in DIY was 23.6%, while the pulp and periapical tissue diseases in the elderly in Sleman districts was approximately 1704 cases. Hence, it was classified as one of the 10 most prevalent diseases in Public Health Centre. In addition, there were 406 older adults who were underweight. Objectives: To investigate the relationship between oral health status, nutrient intake and nutritional status in older adults. Methods: This study is an observational study with cross sectional design. Subjects were 310 patients aged 60-74 years old in Sleman district. Data obtained by interview, examination of the oral health status, measurement of body weight and arm span. Data were analyzed with Chi-square test. Results: There was a significant association between oral health status and protein intake (RP=2.38; 95%CI:1.42-3.970. Energy, fat and carbohydrates intake were not associated with oral health status (p>0,05. Nutritional status was significantly associated with the intake of the energy (RP=2.98, 95%CI:1.58-5.58, protein (RP=2.44, 95%CI:1,05-5.67, fat (RP=3.68, 95%CI:1.93-7.03 and carbohydrates (RP=4.89, 95%CI:2.54-9.4. However, there were no relationship found between oral health and nutritional status (RP=1.79, 95%CI:0.94-3.43. Conclusion: There was a significant association between oral health status and protein intake. The intake of nutrients (energy, protein, fat, and carbohydrate was significantly associated with nutritional status. However, there was no significant relationship found between oral health and nutritional status in older adults.

    To determine if civil status acts as a risk factor in suicide and how it modifies according to gender, age and population size. A retrospective study which analyzes information from the mortality data from the National Institute of Statistics, Geography and Information, from 1998 to 2002. Variables like suicides age, sex, cause of death, federal entity, population size and civil status were registered. Single men showed twofold risk for committing suicide. Women did not show any associated risk for suicide according to civil status. The risk of married men for committing suicide increased gradually with age. Medium-sized communities with less than 19,999 habitants presented the highest risk for habitants to commit suicide. Suicide is associated to gender especially to men who are not married and living in small and medium-sized communities. One explanation could be the lack of integrated behavior as defined by Emile Durkheim, where the physical density of society will determine behavior and ideas. This social structure phenomenon is called the "moral cocoon." This works around the individual being less individualistic and granting him/her the feeling of belonging to a group.

    The report gives an account of the development of material and fabrication technology for copper canisters with cast inserts during the period from 2000 until the start of 2004. The engineering design of the canister and the choice of materials in the constituent components described in previous status reports have not been significantly changed. In the reference canister, the thickness of the copper shell is 50 mm. Fabrication of individual components with a thinner copper thickness is done for the purpose of gaining experience and evaluating fabrication and inspection methods for such canisters. As a part of the development of cast inserts, computer simulations of the casting processes and techniques used at the foundries have been performed for the purpose of optimizing the material properties. These properties have been evaluated by extensive tensile testing and metallographic inspection of test material taken from discs cut at different points along the length of the inserts. The testing results exhibit a relatively large spread. Low elongation values in certain tensile test specimens are due to the presence of poorly formed graphite, porosities, slag or other casting defects. It is concluded in the report that it will not be possible to avoid some presence of observed defects in castings of this size. In the deep repository, the inserts will be exposed to compressive loading and the observed defects are not critical for strength. An analysis of the strength of the inserts and formulation of relevant material requirements must be based on a statistical approach with probabilistic calculations. This work has been initiated and will be concluded during 2004. An initial verifying compression test of a canister in an isostatic press has indicated considerable overstrength in the structure. Seamless copper tubes are fabricated by means of three methods: extrusion, pierce and draw processing, and forging. It can be concluded that extrusion tests have revealed a

Methods: Nutrition risk screening was undertaken by NRS-2002. Sixty patients of over 5 marks were enrolled in this study and were randomized into 2 groups of 30 patients. Parenteral nutritional support was given 5 days before radical gastrectomy. Parental nutrition was continued while only the experiment group was prescribed alanyl-glutamine. Immunologtcal markers, hepatic and renal function markers were monitored by the time of in-charge and 6 days after surgery. The postoperative recovery procedure and complications were carefully recorded. Results: The immune markers of CD4 and CD8 were markedly enhanced in the glutamine group comparing the control groups. There was no significant difference in the incidence of transient hepatic injury. The glutamine group showed a faster albumin restoration, and intestinal peristalsis recovery was also significantly faster in the glutamine group. Diarrhea was less frequent in the glutamine group. Other clinical parameters such as the duration of antibiotic usage, the incidence of postoperative infection revealed no significant differences. Conclusion: For surgical patients with nutritional risk, total parentsral nutrition with glutamine supplementation, in the perioperative period may enhance their immune response, promoting postoperative recovery reduce operation complications.%目的:本研究旨在探讨NRS评分大于5分的胃癌根治术患者围手术期应用丙氨酰谷氨酰胺(Ala-Gln)强化的肠外营养对免疲动能、营养状况及术后恢复情况的临价值.方法:NRS-2002评分大于5分的胃癌患者60例,随机分为两组,每组30例.术前开始给予肠外营养支持,5日后手术,手术方式为根治性胃切除,包括远端胃大部

    Previous studies found that uninsured and Medicaid insured cancer patients have poorer outcomes than cancer patients with private insurance. We examined the association between health insurance status and survival of New Jersey patients 18-64 diagnosed with seven common cancers during 1999-2004. Hazard ratios (HRs) with 95% confidence intervals for 5-year cause-specific survival were calculated from Cox proportional hazards regression models; health insurance status was the primary predictor with adjustment for other significant factors in univariate chi-square or Kaplan-Meier survival log-rank tests. Two diagnosis periods by health insurance status were compared using Kaplan-Meier survival log-rank tests. For breast, colorectal, lung, non-Hodgkin lymphoma (NHL), and prostate cancer, uninsured and Medicaid insured patients had significantly higher risks of death than privately insured patients. For bladder cancer, uninsured patients had a significantly higher risk of death than privately insured patients. Survival improved between the two diagnosis periods for privately insured patients with breast, colorectal, or lung cancer and NHL, for Medicaid insured patients with NHL, and not at all for uninsured patients. Survival from cancer appears to be related to a complex set of demographic and clinical factors of which insurance status is a part. While ensuring that everyone has adequate health insurance is an important step, additional measures must be taken to address cancer survival disparities.

    To describe and compare nutritional status, pulmonary function, gender and marital status in patients with chronic obstructive pulmonary disease. Chronic obstructive pulmonary disease is a chronic illness that can lead to poor nutritional status due to an increased energy requirements related to laboured breathing. Inadequate nutritional intake has often been described in this patient group. Nutritional support for patients with chronic obstructive pulmonary disease who suffer from nutritional problems is essential, both for their sense of well-being and for their survival with chronic obstructive pulmonary disease. The study design was descriptive and comparative. Quantitative data collection was carried out among 81 patients with chronic obstructive pulmonary disease (47 women and 34 men) with an average age of 65 years (SD 3·5). The Mini Nutritional Assessment was used to assess nutritional status. Participants who lived alone had worse nutritional status than those who did not live alone, and female participants had worse nutritional status than their male counterparts. No significant correlation was found between pulmonary function and nutritional status. This study contributes knowledge of a potential correlation between nutritional status, gender and marital status in patients with chronic obstructive pulmonary disease. Women with chronic obstructive pulmonary disease may be at an increased risk of malnutrition. Despite the previous results showing malnutrition and underweight to be common, the present study found that many of the participants were overweight, which may reflect a global health trend regardless of disease. Early identification of patients at risk of malnutrition is important. Registered nurses should be aware that patients with chronic obstructive pulmonary disease who are female or who live alone may be at an increased risk of nutritional problems. Patients with chronic obstructive pulmonary disease must be offered information and support

    To assess the agreement between self-perceived weight status and BMI status, calculated from self-reported height and weight, in nurses and to evaluate the relationship between weight status misperceptions and personal body weight, demographics and health status. Cross-sectional questionnaire survey. A large university in London, UK. Four hundred and fifty-six student nurses and 588 qualified nurses attending university were surveyed; 355 student nurses and 409 qualified nurses completed questionnaires representing a response rate of 78 % and 70 %, respectively. The respondents were mainly female (90·0 %), 66·5 % were white and their mean age was 31 years. Sixty-eight per cent of qualified nurses and 77 % of student nurses correctly perceived their weight status. In logistic regression, (mixed) black ethnicity (OR = 2·53, 95 % CI 1·01, 6·32), overweight by BMI (OR = 3·10, 95 % CI 1·31, 7·33) and ≥3 family histories of obesity co-morbidities (OR = 2·51, 95 % CI 1·04, 6·08) were significantly associated with misperceptions in the sample of student nurses, whereas overweight by BMI (OR = 5·32, 95 % CI 2·66, 10·67) was the only significant variable in the sample of qualified nurses. A substantial proportion of nurses misclassified their weight status. Nurses' misperception of weight status was related to their own BMI status, ethnic background and obesity-related family histories. Being aware of this may help nurses not only promote their own healthy weight, but also fulfil their public health role to practise weight management successfully with both patients and the public. While limitations of the sample mean that the study findings cannot be generalized, they do provide grounds for future larger-scale research.

    The nutritional selenium status of apparently healthy Greeks has been assessed by measuring fluorimetrically the selenium content of whole blood, morning urine, hair and finger nails. The means and standard deviations were 165 +/- 33, 25 +/- 7 ng Se ml-1, 416 +/- 86, and 536 +/- 91 ng Se g-1, respectively. No significant difference was found between the selenium content of whole blood, hair and finger nails, but, for morning urine, there was a significant difference between males and females. The young and the elderly have less selenium in these biological materials than other Greeks. Whole blood selenium correlates significantly with morning urine, hair, and finger nail selenium, as does hair and nail selenium of male, female and male + female Greeks. The results are compared with those in the literature and possible explanations for the observations are presented. It is concluded that the selenium status of Greeks is satisfactory.

    The primary objective for the Model Validation Status Review was to perform a one-time evaluation of model validation associated with the analysis/model reports (AMRs) containing model input to total-system performance assessment (TSPA) for the Yucca Mountain site recommendation (SR). This review was performed in response to Corrective Action Request BSC-01-C-01 (Clark 2001, Krisha 2001) pursuant to Quality Assurance review findings of an adverse trend in model validation deficiency. The review findings in this report provide the following information which defines the extent of model validation deficiency and the corrective action needed: (1) AMRs that contain or support models are identified, and conversely, for each model the supporting documentation is identified. (2) The use for each model is determined based on whether the output is used directly for TSPA-SR, or for screening (exclusion) of features, events, and processes (FEPs), and the nature of the model output. (3) Two approaches are used to evaluate the extent to which the validation for each model is compliant with AP-3.10Q (Analyses and Models). The approaches differ in regard to whether model validation is achieved within individual AMRs as originally intended, or whether model validation could be readily achieved by incorporating information from other sources. (4) Recommendations are presented for changes to the AMRs, and additional model development activities or data collection, that will remedy model validation review findings, in support of licensing activities. The Model Validation Status Review emphasized those AMRs that support TSPA-SR (CRWMS M&O 2000bl and 2000bm). A series of workshops and teleconferences was held to discuss and integrate the review findings. The review encompassed 125 AMRs (Table 1) plus certain other supporting documents and data needed to assess model validity. The AMRs were grouped in 21 model areas representing the modeling of processes affecting the natural and

    Full Text Available The current status of the nuclear data evaluation tool GENEUS (General Nuclear Data Evaluation and Uncertainty System is discussed. Especially, recent improvements of the implemented algorithms concerning smoothness and stability of the evaluated data. These modifications include an improved extrapolation algorithm for the model defect covariance matrices, the inclusion of uncertainties in level densities and charged particle optical model parameters and the employment of a regularization procedure to restore positive semidefiniteness of the prior covariance matrices. The impact of these improvements is studied for the example of neutron-induced cross sections of 55Mn for which preliminary evaluation results are also provided.

    Scleromyxedema is a rare dermatologic disorder, characterized by erythematous or yelowish lichenoid waxy papules. Neurological manifestations are rare but wel-recognized. A 51-year-old woman, diagnosed with scleromyxedema, was admitted to the hospital with status epilepticus, caused by brain lesions, as disclosed in a brain magnetic resonance imaging (MRI). The patient was treated with anticonvulsants and corticosteroids and gradualy recovered fuly. A complete remission of the lesions was shown in a folow-up brain MRI. In cases with scleromyxedema and the presence of neurological manifestations, we need to pay attention to central nervous system involvement, especialy when combined with brain MRI lesions, and treat the patient appropriately.

    The influence of maternal dietary folic acid intake on folate status was studied in Cebus albifrons monkeys by feeding 10 or 250 micrograms/100 kcal dietary folic acid during pregnancy and 4 wk postpartum. Maternal, infant, and nonpregnant hematologic indices; blood and liver folate concentrations; and urinary formiminoglutamic acid excretion all varied with dietary folate intake and pregnancy status as did milk folate concentration in lactating dams. Maternal folate status, determined by plasma, red blood cell, and milk folate concentrations, as well as urinary formiminoglutamic acid excretion, all were correlated significantly with liver folate concentrations in neonates (r = 0.740, r = 0.919, r = 0.936, and r = -0.851, respectively). Results in these primates showed that neonatal folate status was related significantly to the dietary folate intake and folate status of the mother during pregnancy and lactation.

    In this study we examined the relation between personality factors (mastery and interpersonal trust), primary appraisal (the stakes a person has in a stressful encounter), secondary appraisal (options for coping), eight forms of problem- and emotion-focused coping, and somatic health status and psychological symptoms in a sample of 150 community-residing adults. Appraisal and coping processes should be characterized by a moderate degree of stability across stressful encounters for them to have an effect on somatic health status and psychological symptoms. These processes were assessed in five different stressful situations that subjects experienced in their day-to-day lives. Certain processes (e.g., secondary appraisal) were highly variable, whereas others (e.g., emotion-focused forms of coping) were moderately stable. We entered mastery and interpersonal trust, and primary appraisal and coping variables (aggregated over five occasions), into regression analyses of somatic health status and psychological symptoms. The variables did not explain a significant amount of the variance in somatic health status, but they did explain a significant amount of the variance in psychological symptoms. The pattern of relations indicated that certain variables were positively associated and others negatively associated with symptoms.

  8. Age, relationship status, and the planning status of births

    Full Text Available In the United States historically, births to older mothers have been more likely to be planned than births to younger mothers, and births to unmarried women have been less likely to be planned than births to married women. As the average age of mothers has increased and more births have occurred outside of marriage in the United States, the intersection of these trends may have weakened the traditional linkage between age and birth planning status. In this article, we examine differences by maternal age in planning status of births using The 2002 National Survey of Family Growth. We find that age is strongly associated with planning status, but the association is reduced in magnitude when controlling for relationship status and is stronger for first and second births than for higher-parity births. Further, the association between union status and the planning status of births varies by race-ethnicity.

    p16 is a negative regulator of cell proliferation and is considered a tumor suppressor protein. Alterations in p16 protein expression are associated with tumor development and progression. However, the p16 expression status in the peritumoral stroma has not been investigated in the endometrium. Therefore, we evaluated stromal p16 expression in different types of endometrial lesions using immunohistochemistry. Differences in the p16 expression status according to the degree of malignancy and histological type were analyzed. This study included 62, 26, and 36 cases of benign, precancerous, and malignant endometrial lesions, respectively. Most benign lesions showed negative or weak expression, whereas precancerous lesions showed a variable degree of staining proportion and intensity. Atypical hyperplasia/endometrial intraepithelial neoplasia (AH/EIN) and serous endometrial intraepithelial carcinoma (SEIC) had significantly higher stromal p16 expression levels than benign lesions. Endometrioid carcinoma (EC), serous carcinoma (SC), and carcinosarcoma showed significantly elevated stromal p16 expression levels compared with benign and precancerous lesions. In addition, there were significant differences in stromal p16 expression between AH/EIN and SEIC and between EC and SC. In contrast, differences in stromal p16 expression among nonpathological endometrium, atrophic endometrium, endometrial polyp, and hyperplasia without atypia were not statistically significant. Our observations suggest that stromal p16 expression is involved in the development and progression of endometrial carcinoma, and raise the possibility that p16 overexpression in the peritumoral stroma is associated with aggressive oncogenic behavior of endometrial SC.

    The Large Synoptic Survey Telescope (LSST) Project1 received its construction authorization from the National Science Foundation in August 2014. The Telescope and Site (T and S) group has made considerable progress towards completion in subsystems required to support the scope of the LSST science mission. The LSST goal is to conduct a wide, fast, deep survey via a 3-mirror wide field of view optical design, a 3.2-Gpixel camera, and an automated data processing system. The summit facility is currently under construction on Cerro Pachón in Chile, with major vendor subsystem deliveries and integration planned over the next several years. This paper summarizes the status of the activities of the T and S group, tasked with design, analysis, and construction of the summit and base facilities and infrastructure necessary to control the survey, capture the light, and calibrate the data. All major telescope work package procurements have been awarded to vendors and are in varying stages of design and fabrication maturity and completion. The unique M1M3 primary/tertiary mirror polishing effort is completed and the mirror now resides in storage waiting future testing. Significant progress has been achieved on all the major telescope subsystems including the summit facility, telescope mount assembly, dome, hexapod and rotator systems, coating plant, base facility, and the calibration telescope. In parallel, in-house efforts including the software needed to control the observatory such as the scheduler and the active optics control, have also seen substantial advancement. The progress and status of these subsystems and future LSST plans during this construction phase are presented.

    Historically, physicians completed status assignment during the admission process. Incorrect status assignment of patients can result in reimbursement problems and denial of payment by Medicare, Medicaid, and private insurance companies. The purpose of this study was to evaluate the impact of case manager's role with status assignment during the admission process by looking at the denial of payment for services rendered. Denial rates were evaluated for two 15-month time periods: preintervention group (status assignment completed by physicians) and intervention group (status assignment recommended by case managers with physician signature). Denial data for all diagnosis-related groups possessing a more than 2% denial rate related to status assignment were further examined to identify the rationale for denial of payment. FINDINGS/OUTCOMES: The greatest denial rates for payment occurred during the Preintervention Period, when physicians assigned status for patients independently. There was a significant reduction in denial of payment for most diagnosis-related groups during the Intervention time period when case managers were recommending status assignment. Evaluation of denial data provides an opportunity to target creative performance improvement solutions to reduce denial of payment related to incorrect status assignment.

    During the Golden Age of Medicine (20th Century), scientific and technological breakthroughs enabled physicians to treat diseases that were previously incurable. The idealist, romantic approach of medical practice believed in the right of every human being to receive the best treatment possible, regardless of cost. However, the rise in health care expenditure at the end of the last century made this approach impossible to follow. The growing health expenses are due to the increased percentage of chronically sick patients and elderly population, costs of novel technologies and public expectations. Israel spends 7.9% of its GDP on health, a figure which has not changed in the last fifteen years, while other western countries spend a considerably higher and increasing percentage of their GDP on health. Public resources must be allocated in order to maintain the health of the population and to decrease inequities. A data-based demonstration of the population health status and health care system is therefore mandated. in this issue of the Harefuah, three articles are presented which try to show different aspects of the measurement of Israeli heath status. The data accumulated is used to improve the health status of the Israeli people. The Israel Medical Association (IMA) has assumed responsibility for the creation of an objective index for the measurement and evaluation of the public state of health and the healthcare system. The goal of the IMA National Health Index is to promote discussions regarding medicine and health in Israel, and to serve as a tool to be used by relevant policy makers. Prof. Israeli et al discuss the merits of the National Health Index as well as delineate the difficulties regarding the methodology and choice of parameters. They suggest methods for its improvement. Dr Cohen and his colleagues of Clalit Health Services present the Quality Health indicator program in the community. In effect over the past fifteen years, this program is based on

  14. Markups and Firm-Level Export Status

    De Loecker, Jan; Warzynski, Frederic

    We derive an estimating equation to estimate markups using the insight of Hall (1986) and the control function approach of Olley and Pakes (1996). We rely on our method to explore the relationship between markups and export behavior using plant-level data. We find significantly higher markups when...... we control for unobserved productivity shocks. Furthermore, we find significant higher markups for exporting firms and present new evidence on markup-export status dynamics. More specifically, we find that firms' markups significantly increase (decrease) after entering (exiting) export markets. We...

    TAROT-1 is an automatic, autonomous ground based observatory whose primary goal is the rapid detection of the optical counterparts of cosmic gamma-ray burst sources. It will be able to begin imaging any GRB localization 8 seconds after receipt of an alert from CGRO/BATSE or HETE-2. TAROT-1 will reach the 17th V magnitude in 10 seconds, at a 10$\\sigma$ confidence level. TAROT will be able to observe GRB positions given by Beppo-SAX or RXTE, EUV transients from ALEXIS alerts, etc. TAROT will also study a wide range of secondary objectives and will feature a complete automatic data analysis system, and a powerful scheduling software. TAROT will be installed this fall on the Plateau du Calern, 1200m above sea level. We report on the status of the project.

  16. Status of French reactors

    The status of French reactors is reviewed. The ORPHEE and RHF reactors can not be operated with a LEU fuel which would be limited to 4.8 g U/cm{sup 3}. The OSIRIS reactor has already been converted to LEU. It will use U{sub 3}Si{sub 2} as soon as its present stock of UO{sub 2} fuel is used up, at the end of 1994. The decision to close down the SILOE reactor in the near future is not propitious for the start of a conversion process. The REX 2000 reactor, which is expected to be commissioned in 2005, will use LEU (except if the fast neutrons core option is selected). Concerning the end of the HEU fuel cycle, the best option is reprocessing followed by conversion of the reprocessed uranium to LEU.

    Installation of Advanced LIGO, a second-generation interferometric gravitational wave observatory, began in earnest in October of 2010. Initial LIGO instrumentation was de-installed, vacuum chambers and envelope modified, and the installation of scientific payloads begun. At LIGO Hanford Observatory, optics and suspensions comprising one of two 4km Fabry-Perot arms have been deployed and commissioned, resonating green light in an experiment to test and understand the process of controlling cavity lengths (``lock acquisition''). At LIGO Livingston, cornerstation optic and seismic isolation installation has matured such that the primary infrared laser and a suspended mode cleaner cavity (employed to spacially clean the interferometer input beam) are locked and under commissioning test. In this talk we present the status of Advanced LIGO installation and integration, and sketch the promising future of gravitational wave observation and astronomy.

    2012-04-01

    Refractory status epilepticus (RSE) has a high morbidity and mortality. There are currently no definitive data to guide both the optimal choice of therapy and treatment goals. This review focuses on RSE diagnosis and outcome and discusses both commonly used and anecdotal therapies for RSE. The challenges in performing randomized controlled trials (RCTs) in neurocritical care and more specifically for the treatment of RSE are illustrated by the early termination of the first RCT of RSE due to low recruitment that compared propofol to barbiturates. Recent case series include the successful treatment of recurrent RSE with ketamine, intravenous lacosamide as an add-on treatment, the use of combination antiepileptics (phenytoin, levetiracetam, and pregabalin), and surgical treatments (vagal nerve and deep brain stimulation) for the control of RSE. A number of different therapeutic options are available for the treatment of RSE but none have been shown to be superior to others at this point.

    The development of the Advanced Life Support (ALS) Sizing Analysis Tool (ALSSAT) using Microsoft(Registered TradeMark) Excel was initiated by the Crew and Thermal Systems Division (CTSD) of Johnson Space Center (JSC) in 1997 to support the ALS and Exploration Offices in Environmental Control and Life Support System (ECLSS) design and studies. It aids the user in performing detailed sizing of the ECLSS for different combinations of the Exploration Life support (ELS) regenerative system technologies. This analysis tool will assist the user in performing ECLSS preliminary design and trade studies as well as system optimization efficiently and economically. The latest ALSSAT related publication in ICES 2004 detailed ALSSAT s development status including the completion of all six ELS Subsystems (ELSS), namely, the Air Management Subsystem, the Biomass Subsystem, the Food Management Subsystem, the Solid Waste Management Subsystem, the Water Management Subsystem, and the Thermal Control Subsystem and two external interfaces, including the Extravehicular Activity and the Human Accommodations. Since 2004, many more regenerative technologies in the ELSS were implemented into ALSSAT. ALSSAT has also been used for the ELS Research and Technology Development Metric Calculation for FY02 thru FY06. It was also used to conduct the Lunar Outpost Metric calculation for FY08 and was integrated as part of a Habitat Model developed at Langley Research Center to support the Constellation program. This paper will give an update on the analysis tool s current development status as well as present the analytical results of one of the trade studies that was performed.

  2. Biomarkers of Selenium Status

    Gerald F. Combs, Jr.

    2015-03-01

    Full Text Available The essential trace element, selenium (Se, has multiple biological activities, which depend on the level of Se intake. Relatively low Se intakes determine the expression of selenoenzymes in which it serves as an essential constituent. Higher intakes have been shown to have anti-tumorigenic potential; and very high Se intakes can produce adverse effects. This hierarchy of biological activities calls for biomarkers informative at different levels of Se exposure. Some Se-biomarkers, such as the selenoproteins and particularly GPX3 and SEPP1, provide information about function directly and are of value in identifying nutritional Se deficiency and tracking responses of deficient individuals to Se-treatment. They are useful under conditions of Se intake within the range of regulated selenoprotein expression, e.g., for humans <55 μg/day and for animals <20 μg/kg diet. Other Se-biomarkers provide information indirectly through inferences based on Se levels of foods, tissues, urine or feces. They can indicate the likelihood of deficiency or adverse effects, but they do not provide direct evidence of either condition. Their value is in providing information about Se status over a wide range of Se intake, particularly from food forms. There is need for additional Se biomarkers particularly for assessing Se status in non-deficient individuals for whom the prospects of cancer risk reduction and adverse effects risk are the primary health considerations. This would include determining whether supranutritional intakes of Se may be required for maximal selenoprotein expression in immune surveillance cells. It would also include developing methods to determine low molecular weight Se-metabolites, i.e., selenoamino acids and methylated Se-metabolites, which to date have not been detectable in biological specimens. Recent analytical advances using tandem liquid chromatography-mass spectrometry suggest prospects for detecting these metabolites.

    The US is providing 7 diagnostics to ITER: the Upper Visible/IR cameras, the Low Field Side Reflectometer, the Motional Stark Effect diagnostic, the Electron Cyclotron Emission diagnostic, the Toroidal Interferometer/Polarimeter, the Core Imaging X-Ray Spectrometer, and the Diagnostic Residual Gas Analyzer. The front-end components of these systems must operate with high reliability in conditions of long pulse operation, high neutron and gamma fluxes, very high neutron fluence, significant neutron heating (up to 7 MW/m3) , large radiant and charge exchange heat flux (0.35 MW/m2) , and high electromagnetic loads. Opportunities for repair and maintenance of these components will be limited. These conditions lead to significant challenges for the design of the diagnostics. Space constraints, provision of adequate radiation shielding, and development of repair and maintenance strategies are challenges for diagnostic integration into the port plugs that also affect diagnostic design. The current status of design of the US ITER diagnostics is presented and R&D needs are identified. Supported by DOE contracts DE-AC02-09CH11466 (PPPL) and DE-AC05-00OR22725 (UT-Battelle, LLC).

    Propofol is used for treating refractory status epilepticus, which has high rate of mortality. Propofol infusion syndrome is a rare but often fatal syndrome, characterized by lactic acidosis, lipidemia, and cardiac failure, associated with propofol infusion over prolonged periods of time. We investigated the clinical factors that characterize propofol infusion syndrome to know the risk of them in refractory status epilepticus. This retrospective observation study was conducted in Samsung medical center from Jan. 2005 to Dec. 2009. Thirty two patients (19 males, 13 females, aged between 16 and 64 years), with refractory status epilepsy were included. Their clinical findings and treatment outcomes were evaluated retrospectively. We divided our patients into established status epilepticus (ESE) and refractory status epilepticus (RSE). And then the patients with RSE was further subdivided into propofol treatment group (RSE-P) and the other anesthetics treatment group (RSE-O). We analyzed the clinical characteristics by comparison of the groups. There were significant differences of hypotension and lipid change between ESE and RSE (pRSE-P and RSE-O groups. The hospital days were longer in RSE than in ESE (p=0.012) and treatment outcome was also worse in RSE than in ESE (p=0.007) but there were no significant differences of hospital stays and treatment outcome between RSE-P and RSE-O. RSE is very critical disease with high mortality, which may show as many clinical changes as propofol infusion syndrome. Therefore propofol infusion syndrome might be considered as one of the clinical manifestations of RSE.

    Full Text Available It is obvious that malnutrition is extremely dominant in end-stage renal disease (ESRD patients. Malnutrition in pre-dialysis, dialysis, and post-dialysis stages is related to multiple factors. However, research work shows that if we try to improve the poor nutrition status of ESRD patients, good clinical outcomes may result. But the long-term effect of nutrition in the presence of other comorbid conditions has not been well established by many studies. So this aspect of nutrition is still researchable. Some studies emphasise that malnutrition is a major comorbid condition in ESRD victims as are hypertension, diabetes mellitus (DM and cardiovascular disease. Researchers believe that the nutritional status, treatment and diagnostic parameters of these patients should be altered to achieve progress not only in their mortality outcome, but also in their quality of life

    Full Text Available Research on personality has shown that perceiving a person as attractive fosters positive expectations about his/her personal characteristics. Literature has also demonstrated a significant link between personality traits and occupational achievement. Present research examines the combined effects of attractiveness, occupational status, and gender on the evaluation of others’ personality, according to the Big Five model. The study consisted of a 2 (Attractiveness: High vs. Low x 2 (occupational Status: High vs. Low x 2 (Target gender: Male vs. Female between-subjects experimental design (N = 476. Results showed that attractive targets were considered more positively than unattractive targets, and this effect was even stronger for male targets. Occupational status influenced perceived agreeableness (lower for high-status targets and perceived conscientiousness (higher for high-status targets.

    Few longitudinal studies have analyzed how socioeconomic status (SES) influences both depressive and cognitive development over an individual's life course. This study investigates the change trajectories of both depressive symptomatology and general cognitive status, as well as their associations over time, focusing on the effects of mid-life SES. Data were obtained from the Taiwan Longitudinal Study on Aging (1993-2007), a nationally representative cohort study of older adults in Taiwan. The short form of the Center of Epidemiological Studies-Depression (CES-D) scale that measures depressive symptomatology in two domains (negative affect and lack of positive affect) was used. General cognitive status was assessed using the brief Short Portable Mental Status Questionnaire scale. Assessments of the subjects' mid-life SES included measurement of the participant's education and occupation. Analyses were conducted by the parallel latent growth curve modeling. The participants' initial levels of depressive symptomatology and general cognitive status were significantly and negatively correlated; furthermore, any changes in these two outcomes were also correlated over time. The initial assessment of general cognitive status significantly contributed to any advancement towards more severe depressive symptomatology over time, particularly when this occurred in a negative manner. Furthermore, a mid-life SES advantage resulted in a significant reduction in late-life depressive symptomatology and also produced a slower decline in general cognitive status during later life. In contrast, lower mid-life SES exacerbated depressive symptomatology during old age, both at the initial assessment and in terms of the change over time. In addition, female gender was significantly associated with lower general cognitive status and more severe depressive symptomatology in negative affect. These findings suggest a complex and longitudinal association between depressive symptomatology and

    The French-Italian interferometric gravitational wave detector VIRGO is currently being commissioned. Its principal instrument is a Michelson interferometer with 3 km long optical cavities in the arms and a power-recycling mirror. This paper gives an overview of the present status of the system. We report on the presently attained sensitivity and the system's performance during the recent commissioning runs. After a sequence of intermediate stages, the interferometer is now being used in the so-called recombined configuration. The input laser beam is spatially filtered by a 144 m long input mode-cleaner before being injected to the main interferometer. The main optics are suspended from so-called \\sa s, which provide an excellent seismic isolation. The two 3 km long Fabry-Perot arm cavities are kept in resonance with the laser light, and the Michelson interferometer is held on the dark fringe. An automatic mirror alignment system based on the Anderson technique has been implemented for the arm cavities. The l...

    Kumar, Rajiv; Singh, Jagjit

    2014-07-01

    Biologic products are being developed over the past three decades. The expiry of patent protection for many biological medicines has led to the development of biosimilars in UK or follow on biologics in USA. This article reviews the literature on biosimilar drugs that covers the therapeutic status and regulatory guidelines. Appraisal of published articles from peer reviewed journals for English language publications, search from PubMed, and guidelines from European Medicines Agency, US Food Drug Administration (FDA) and India were used to identify data for review. Literature suggest that biosimilars are similar biological products, i.e., comparable but not identical to the reference product, are not generic version of innovator product and do not ensure therapeutic equivalence. Biosimilars present more challenges than conventional generics and marketing approval is also more complicated. To improve access, US Congress passed the Biologics Price Competition and Innovation act 2009 and US FDA allowed "abbreviated pathway" for their approval. U.S law has defined new standards and terms and EMA scientific guidelines have also set detailed approval standards. India being one of the most preferred manufacturing destinations of biosimilars, there is a need for stringent safety and regulatory guidelines. The New India Guidelines "Draft Guidelines on Similar Biologics were announced in June 2012, by Department of Biotechnology at Boston bio and available online.

    With the delivery of the instruments to the spacecraft builder, the Solar Orbiter mission is in the midst of Integration & Testing phase at Airbus in Stevenage, U.K. This mission to “Explore the Sun-Heliosphere Connection” is the first medium-class mission of ESA’s Cosmic Vision 2015-2025 program and is being jointly implemented with NASA. The dedicated payload of 10 remote-sensing and in-situ instruments will orbit the Sun as close as 0.3 A.U. and will provide measurments from the photosphere into the solar wind. The three-axis stabilized spacecraft will use Venus gravity assists to increase the orbital inclination out of the ecliptic to solar latitudes as high as 34 degrees in the extended mission. The science team of Solar Orbiter has been working closely with the Solar Probe Plus scientists to coordinate observations between these two highly-complementary missions. This will be a status report on the mission development; the interested reader is referred to the recent summary by Müller et al., Solar Physics 285 (2013).

    ANAIS experiment will look for dark matter annual modulation with large mass of ultra-pure NaI(Tl) scintillators at the Canfranc Underground Laboratory (LSC), aiming to confirm the DAMA/LIBRA positive signal in a model-independent way. Two 12.5 kg each NaI(Tl) crystals provided by Alpha Spectra are currently taking data at the LSC. Present status of ANAIS detectors background and general performance is summarized; in particular, thanks to the high light collection efficiency prospects of lowering the threshold down to 1 keVee are reachable. Crystal radiopurity goals are fulfilled for $^{232}$Th and $^{238}$U chains and $^{40}$K activity, although higher than original goal, could be accepted; however, high $^{210}$Pb contamination out-of-equilibrium has been identified. More radiopure detectors are being built by Alpha Spectra. The ongoing high quantum efficiency PMT tests and muon veto characterization are also presented. Finally, the sensitivity of the experiment for the annual modulation in the WIMP signal,...

    The TESLA Test Facility (TTF), under construction at DESY by an international collaboration, is an R and D test bed for the superconducting option for future linear e+/e-colliders. It consists of an infrastructure to process and test the cavities and of a 500 MeV linac. The infrastructure has been installed and is fully operational. It includes a complex of clean rooms, an ultra-clean water plant, a chemical etching installation and an ultra-high vacuum furnace. The linac will consist of four cryo-modules, each containing eight 1 meter long nine-cell cavities operated at 1.3 GHz. The base accelerating field is 15 MV/m. A first injector will deliver a low charge per bunch beam, with the full average current (8 mA in pulses of 800 {mu}s). A more powerful injector based on RF gun technology will ultimately deliver a beam with high charge and low emittance to allow measurements necessary to qualify the TESLA option and to demonstrate the possibility of operating a free electron laser based on the Self-Amplified-Spontaneous-Emission principle. Overview and status of the facility will be given. Plans for the future use of the linac are presented. (R.P.). 19 refs.

    We are building a momentum achromat recoil spectrometer (MARS) for use with the new K500 superconducting cyclotron at Texas A and M University. MARS uses a unique optical design utilizing two dispersive planes to combine a momemtum achromat with a recoil mass spectrometer. This configuration makes MARS applicable to a broad range of nuclear reaction studies utilizing inverse kinematics. It also leads to a system that is well matched to the range of secondary particle energies that will be produced in reactions with K500 beam. MARS will have a typical mass resolution of {delta}M/M{approx equal}1/300, with an energy acceptance of {+-}9% {Delta}E/E and a geometric solid angle of up to 9 msr. A beam swinger system will alow reaction products in the angular range 0deg to 30deg to be studied. MARS will be used to study both the excited states and decay properties of very proton- and neutron-rich nuclei. MARS will also be used to provide a reaction mechanism filter to assist investigations of the dynamics of heavy ion collisions and to produce secondary radioactive beams for reaction and spectroscopic studies of particular interest for nuclear astrophysics. We briefly describe the design of MARS, give a status report on its construction and an overview of the scientific program planned for it. (orig.).

    ESR (Westergen) correlated significantly with the iron status (as measured by Hb concentration, haematocrit, red cell count, MCH, P/H ratio, serum iron, TIBC and percent saturation of transferrin) in a group of pregnant women (PW) at term. Serum ferritin correlated negatively with the ESR but the correlation was not statistically significant. Serum ferritin levels of or = 50 mm 1st hour and 5 (19.2%) PW with ESR or = 50 mm 1st hour in 50% and 50 micrograms/L had ESR > or = 50 mm 1st hour, suggesting the possible effect of chronic infection in raising ferritin levels in these PW.

    Objective: to study the clinical significance of Pglycoprotein (P-gp) in breast cancer. Methods: Expression of P-gp in 60 cases of breast cancer was examined by immunohistochemistry. P-gp expression and response to chemotherapy were comparatively investigated in 19 patients with metastatic breast cancer. Results: The P-gp was positive in 48.3% of the 60 cases of breast cancer. P-gp expression was not related to patients' age, menstruation status, number of axillary lymph nodes involved, clinical stage, histological type, and hormonal receptor status (P>0.05). The frequency of metastasis (62.1%) and mortality (51.7%) were higher in P-gp positive cases than in negative cases (16.1% vs 12.9%, P<0.005). The 5-year survival rate of P-gp positive cases (48.3%) was significantly lower than that of negative cases (87.1%) (P<0.05). In patients who received adjuvant chemotherapy distant metastasis occurred more frequently in the P-gp positive cases (94.7%) than in the P-gp negative cases (57.1%) (P=0.0468). More P-gp negative patients (7/9) than positive patients (1/10) were responsive to chemotherapy (P=0.0055).Conclusion: Immunohistochemical examination of P-gp expression is useful in predicting response to chemotherapy and prognosis in breast cancer patients. P-gp positivity is associated with poor prognosis.

    Full Text Available Abstract Background Selenium (Se status in non-deficient subjects is typically assessed by the Se contents of plasma/serum. That pool comprises two functional, specific selenoprotein components and at least one non-functional, non-specific components which respond differently to changes in Se intake. A more informative means of characterizing Se status in non-deficient individuals is needed. Methods Multiple biomarkers of Se status (plasma Se, serum selenoprotein P [SEPP1], plasma glutathione peroxidase activity [GPX3], buccal cell Se, urinary Se were evaluated in relation to selenoprotein genotypes (GPX1, GPX3, SEPP1, SEP15, dietary Se intake, and parameters of single-carbon metabolism in a cohort of healthy, non-Se-deficient men (n = 106 and women (n = 155. Conclusions Plasma Se concentration was 142.0 ± 23.5 ng/ml, with GPX3 and serum-derived SEPP1 calculated to comprise 20% and 34%, respectively, of that total. The balance, comprised of non-specific components, accounted for virtually all of the interindividual variation in total plasma Se. Buccal cell Se was associated with age and plasma homocysteine (hCys, but not plasma Se. SEPP1 showed a quadratic relationship with body mass index, peaking at BMI 25-30. Urinary Se was greater in women than men, and was associated with metabolic body weight (kg0.75, plasma folate, vitamin B12 and hCys (negatively. One GPX1 genotype (679T/T was associated with significantly lower plasma Se levels than other allelic variants. Selenium intake, estimated from food frequency questionnaires, did not predict Se status as indicated by any biomarker. These results show that genotype, methyl-group status and BMI contribute to variation in Se biomarkers in Se-adequate individuals.

    There is interest in age-related cognitive decline and environmental risk factors for Alzheimer's disease (AD). This interest is focused on individual differences in exposure to agents that may harm or protect cognitive function. Caffeine is used as a short acting mental stimulant and may possess longer-term properties that protect against age-related decline and, possibly, AD. The current study aimed to: 1) examine current cognitive function in a narrow age range sample (n=351) without dementia (MMSE>25) who are, by reason of age, entering the period of increased risk of AD; and 2) link cognitive function to self-reported intake of caffeine and socioeconomic status (SES). Possible confounding by gender, childhood intelligence, education, and symptoms of anxiety and depression was introduced into the statistical model. There were significant differences between SES groups in caffeine intake (pcognitive performance (pcaffeine intake were associated with slower digit symbol speed (F =3.38, pcaffeine during cognitive testing and strong links between SES and cognitive performance. No evidence in support of cognitive enhancing effects of caffeine was found.

    The older population is increasing worldwide and in many countries older people will outnumber younger people in the near future. This projected growth in the older population has the potential to place significant burdens on healthcare and support services. Meeting the diet and nutrition needs of older people is therefore crucial for the maintenance of health, functional independence and quality of life. While many older adults remain healthy and eat well those in poorer health may experience difficulties in meeting their nutritional needs. Malnutrition, encompassing both under and over nutrition increases health risks in the older population. More recently the increase in obesity, and in turn the incidence of chronic disease in older adults, now justifies weight management interventions in obese older adults. This growing population group is becoming increasingly diverse in their nutritional requirements. Micro-nutrient status may fluctuate and shortfalls in vitamin D, iron and a number of other nutrients are relatively common and can impact on well-being and quality of life. Aging presents a number of challenges for the maintenance of good nutritional health in older adults.

    The Utility PhotoVoltaic Group (UPVG) was formed in October of 1992 with a mission to accelerate the use of cost-effective small-scale and emerging grid-connected applications of photovoltaics for the benefit of electric utilities and their customers. The UPVG is now implementing a program to install up to 50 megawatts of photovoltaics in small-scale and grid-connected applications. This program, called TEAM-UP, is a partnership of the U.S. electric utility industry and the U.S. Department of Energy to help develop utility PV markets. TEAM-UP is a utility-directed program to significantly increase utility PV experience by promoting installations of utility PV systems. Two primary program areas are proposed for TEAM-UP: (1) Small-Scale Applications (SSA)—an initiative to aggregate utility purchases of small-scale, grid-independent applications; and (2) Grid-Connected Applications (GCA)—an initiative to identify and competitively award cost-sharing contracts for grid-connected PV systems with high market growth potential, or collective purchase programs involving multiple buyers. This paper describes these programs and outlines the schedule, the procurement status, and the results of the TEAM-UP process.

    In Part I of this study, the Human Nutrition Research Center of the United States Department of Agriculture's Nutritional Status Study (NSS) of 691 independently living elderly people aged 60-98 found that poor dietary quality was associated with low educational attainment, low median family income, and self-report of partial or full dentures. In Part II, further analysis was conducted on a random subsample of 181 subjects who were examined and divided into four groups according to dentate status: two dentures, one denture, partial dentures, and teeth. In this subgroup, significant correlations were found between the quality of nutrient intake and the degree of edentulousness. Analysis of 53 nutrients plus calories from three-day food records showed a significantly higher nutritional quality of the diet in dentate volunteers than in the other groups. This difference was approximately 20% for 19 nutrients, bringing some nutrients (such as calcium) below the RDA for this age group. Although direct correlations cannot be made with actual nutritional status, the introduction of dentures could further compromise the precarious nutritional intake of the elderly population. With this in mind, dentists need to consider carefully the importance of their elderly patients maintaining at least some natural dentition and should provide adequate information on nutritional adaptations to dentures.

Nur bei der Hälfte der Patienten mit SE besteht zuvor eine Epilepsie; die meisten Fälle sind symptomatisch, wobei Schädel- Hirn-Traumata, zerebrovaskuläre Erkrankungen, ZNS-Infektionen und metabolische Ursachen führend sind. Bei Patienten mit vorbestehender Epilepsie lässt sich eine frühe Phase des GKSE erkennen, in der die Anfälle crescendoartig zunehmen, bis sie in kontinuierliche Anfallsaktivität münden (etablierte Phase. Das Management eines GKSE verlangt rasches und beherztes Vorgehen. Neben der sofort einzuleitenden Therapie muss gleichzeitig die artdiagnostische Zuordnung des SE und die Ursache erkannt und behandelt werden. Als Therapie der ersten Wahl sind Benzodiazepine etabliert, wobei intravenösem (i.v. Lorazepam gegenüber Diazepam der Vorzug zu geben ist.

    Full Text Available OBJECTIVES: Diabetes mellitus type 2 (DM 2 patients' self-perception of their weight status is very critical in diabetes care. We sought to investigate perception of weight status in a sample of 200 DM 2 patients attending an outpatient clinic at a Teaching Hospital and compared it with their BMI-measured weight status, with a focus on underestimation of their weight status. Factors associated with underestimation of weight status in this sample were also explored. METHODS: Using a cross-sectional design, anthropometric and clinical variables were assessed using appropriate tools. Questionnaires were used to collect socio-demographic data and self-perception of weight status. Self-perceived weight status was compared to BMI-measured weight status by cross-tabulation, Kappa statistics of agreement and χ2 for trend analysis. Both univariate and multiple logistic regression analysis were conducted to identify factors associated with underestimation of weight status. RESULTS: The prevalence of general overweight/obesity and abdominal obesity was 32.0% (n = 64 and 58.0% (n = 116 respectively. Generally, 58.0% (n = 116 of the participants had a distorted weight perceived weight status in which 77.6% (n = 90 underestimated their weight status. Factors associated with underestimation of weight status were being overweight/obese (AOR = 22.9, 95% CI = 8.30-63.07, p<0.001, not married (AOR = 3.7, 95% CI = 1.50-9.17, p = 0.005 and never tried to lose weight (AOR = 6.9, 95% CI = 2.35-19.97, p<0.001. Participants aged over 40 years and those being hyperglycaemic were not significantly associated to underestimation of weight status. CONCLUSION: We found a substantial discordance between BMI-measured and self-perceived weight status. Factors that were associated with underestimation of weight status were being; overweight/obese, not married and never tried to lose weight. Diabetes patients should be provided with

    1992-01-01

    Over the past decade, univariate studies have identified peer-rated popularity/sociability as a correlate of individual health practices (e.g., alcohol and drug use, exercise habits). Yet, the relationship between multiple health habits and broader social competencies rarely has been systematically examined. Accordingly, using a multivariate approach, the present study investigated the relative influence of background characteristics (i.e., age, gender, race, family type, and socioeconomic status) and peer status on health-related behaviors (i.e., physical activity, eating habits, smoking, alcohol use, and stress-related behaviors) in 589 junior high school students (ages 11-13). In this sample, peer popularity provided no significant increment in the prediction of health habits over and above the effects explained by demographics. These results are consistent with current perspectives on health and interpersonal behaviors, and have important practical implications for the initiation and maintenance of healthful and risky practices in the natural environment.

    Status epilepticus is the most severe form of epilepsy, with a high mortality rate and high health care costs. Status epilepticus is divided into four stages: early, established, refractory, and super-refractory. While initial treatment with benzodiazepines has become standard of care for early status epilepticus, treatment after benzodiazepine failure (established status epilepticus (ESE)) is incompletely studied. Effective treatment of ESE is critical as morbidity and mortality increases dramatically the longer convulsive status epilepticus persists. Phenytoin/fosphenytoin, valproic acid, levetiracetam, phenobarbital, and lacosamide are the most frequently prescribed antiseizure medications for treatment of ESE. To date there are no class 1 data to support pharmacologic recommendations of one agent over another. We review each of these medications, their pharmacology, the scientific evidence in support and against each in the available literature, adverse effects and safety profiles, dosing recommendations, and limitations of the available evidence. We also discuss future directions including the established status epilepticus treatment trial (ESETT). Substantial further research is urgently needed to identify these patients (particularly those with non-convulsive status epilepticus), elucidate the most efficacious antiseizure treatment with head-to-head randomized prospective trials, and determine whether this differs for convulsive vs. non-convulsive ESE.

    The purpose of this study was to (1) examine the association between weight status and men's positive mental health, defined as the presence of symptoms of emotional, psychological, and social well-being, and (2) evaluate the moderating effect of marital status. A total of 645 men aged between 19 and 71 years self-reported their height and weight and answered a questionnaire measuring their emotional, psychological, and social well-being. Analysis of variance revealed that mean levels of emotional, psychological, and social well-being did not significantly differ according to men's weight status. Moderation analyses indicated that, for men in a relationship (married or living common-law), there were no significant associations between overweight, obesity, and the three components of positive mental health. However, for single men, overweight was marginally associated with higher emotional well-being, while obesity was associated with lower psychological well-being and marginally associated with lower social well-being. Results of the present study suggest that health professionals and researchers should take the characteristics (such as marital status) of men with obesity and overweight into account when working with them. Mental health researchers may need to examine men in each weight category separately (e.g. obesity vs. overweight), since the association with positive mental health can differ from one category to another.

Utilizing the Karnofski scale we measured the functional status of 200 Patients who had been on maintenance hemodialysis for at least 12 months. A Marnofski scale of less than 70 incidents frank disability (Inability to perform routine living activities without assistance, in addition current vocational status was assessed as well as any existing comorbid conditions. The mean age of the study group was 45.2 years (range 16 to 70 and included 108 (54% males and 92 (46% females, there were 39 (19.5% diabetic patients and 27 (13.5% patients were receiving erythropoietin (EPO. The mean hematocrit of the entire group was 27.8%. As measured by Karnofski scale, 64 (32% of the patients were unable to perform routine living activity without assistance; dependence on wheelchair was reported by 9 (4.5% patients. The mean comorbidity index of patients who scored less than 70 on the Karnofski scale was 1.5 compared to 0.7 for those who scored at least 70 on the same scale (p< 0.001. Analysis of factors showed that age and diabetes mellitus affected functional status. Of the laboratory variables measured, only serum albumin concentration correlated significant with Karnofski scale. Fourteen (21.8% of the patients who scored below 70, had serum albumin concentration above 40g/L compared to 66 (48.5% of the patients who scored at least 70 on the Karnofski scale (p< 0.001. We conclude that a significant proportion of patients on maintenance hemodialysis is functionally disabled. The elderly, diabetics, patients with high co-morbidity index and those with low serum albumin are most likely to have poor functional status.

    Full Text Available Introduction: Glycated hemoglobin (HbA1c can be altered in different conditions. We hypothesize that HbA1c levels may change due to altered thyroid status, possibly due to changes in red blood cell (RBC turnover. Objectives: The objective of this study was to determine the effects of altered thyroid status on HbA1c levels in individuals without diabetes, with overt hyper- and hypo-thyroidism, and if present, whether such changes in HbA1c are reversed after achieving euthyroid state. Methods: Euglycemic individuals with overt hypo- or hyper-thyroidism were selected. Age- and sex-matched controls were recruited. Baseline HbA1c and reticulocyte counts (for estimation of RBC turnover were estimated in all the patients and compared. Thereafter, stable euthyroidism was achieved in a randomly selected subgroup and HbA1c and reticulocyte count was reassessed. HbA1c values and reticulocyte counts were compared with baseline in both the groups. Results: Hb A1c in patients initially selected was found to be significantly higher in hypothyroid group. HbA1c values in hyperthyroid patients were not significantly different from controls. HbA1c reduction and rise in reticulocyte count were significant in hypothyroid group following treatment without significant change in glucose level. Hb A1c did not change significantly following treatment in hyperthyroid group. The reticulocyte count, however, decreased significantly. Conclusion: Baseline HbA1c levels were found to be significantly higher in hypothyroid patients, which reduced significantly after achievement of euthyroidism without any change in glucose levels. Significant baseline or posttreatment change was not observed in hyperthyroid patients. Our study suggests that we should be cautious while interpreting HbA1c data in patients with hypothyroidism.

    We aimed to study whether ketogenic diet (KD) therapy leads to resolution of super-refractory status epilepticus in pediatric patients without significant harm. A retrospective review was performed at Phoenix Children's Hospital on patients with super-refractory status epilepticus undergoing ketogenic diet therapy from 2011 to 2015. Ten children with super-refractory status epilepticus, ages 2-16 years, were identified. 4/10 patients had immune mediated encephalitis, including Rasmussen encephalitis, anti-N-methyl-d-aspartate receptor encephalitis, and post-infectious mycoplasma encephalitis. Other etiologies included Lennox Gastaut Syndrome, non-ketotic hyperglycinemia, PCDH19 and GABRG2 genetic epilepsy, New Onset Refractory Status Epilepticus, and Febrile Infection-Related Epilepsy Syndrome. 4/10 patients' EEG features suggested focal with status epilepticus, and 6/10 suggested generalized with status epilepticus. Median hospital length was 61days and median ICU length was 27days. The median number of antiepileptic medications prior to diet initiation was 3.0 drugs, and the median after ketogenic diet treatment was 3.5 drugs. Median duration of status epilepticus prior to KD was 18days. 9/10 patients had resolution of super-refractory status epilepticus in a median of 7days after diet initiation. 8/9 patients were weaned off anesthesia within 15days of diet initiation, and within 1day of achieving ketonuria. 1/10 patients experienced side effects on the diet requiring supplementation. Most patients achieved resolution of status epilepticus on KD therapy, suggesting it could be an effective therapy that can be utilized early in the treatment of children with super refractory status epilepticus.

    Mortality rates in the United States vary based on race, individual economic status and neighborhood. Correlations among these variables in most urban areas have limited what conclusions can be drawn from existing research. Our study employs a unique factorial design of race, sex, age and individual poverty status, measuring time to death as an objective measure of health, and including both neighborhood economic status and income inequality for a sample of middle-aged urban-dwelling adults (N = 3675). At enrollment, African American and White participants lived in 46 unique census tracts in Baltimore, Maryland, which varied in neighborhood economic status and degree of income inequality. A Cox regression model for 9-year mortality identified a three-way interaction among sex, race and individual poverty status (p = 0.03), with African American men living below poverty having the highest mortality. Neighborhood economic status, whether measured by a composite index or simply median household income, was negatively associated with overall mortality (pincome inequality was associated with mortality through an interaction with individual poverty status (p = 0.04). While racial and economic disparities in mortality are well known, this study suggests that several social conditions associated with health may unequally affect African American men in poverty in the United States. Beyond these individual factors are the influences of neighborhood economic status and income inequality, which may be affected by a history of residential segregation. The significant association of neighborhood economic status and income inequality with mortality beyond the synergistic combination of sex, race and individual poverty status suggests the long-term importance of small area influence on overall mortality.

    Children from immigrant families may be at risk for iron deficiency (ID) due to differences in pre-migration and post-migration exposures. Our objectives were to determine whether there is an association between family immigrant status and iron stores and to evaluate whether known dietary, environmental or biological determinants of low iron status influence this relationship. This was a cross-sectional study of healthy urban preschool children (12-72 months) recruited from seven primary care practices in Toronto. Laboratory assessment of serum ferritin and haemoglobin and standardised parent-completed surveys were completed between 2008 and 2013 during routine health maintenance visits. Multiple regression analyses were used to evaluate the association between family immigrant status and serum ferritin, ID (ferritin iron deficiency anaemia (IDA) (ferritin children included in the analysis, 47.6% had immigrant family status. The median serum ferritin was 30 μg/L and 10.4% of all children had ID and 1.9% had IDA. After adjusting for maternal ethnicity and education, age, sex, income quintile, cow's milk intake, breastfeeding duration and bottle use, there were no significant associations between immigrant status and ferritin, ID or IDA. Significant predictors of low iron status included age, sex, cow's milk intake and breastfeeding duration. We found no association between family immigrant status and iron status after including clinically important covariates in the models. These data suggest immigrant children may not need enhanced screening for iron status or targeted interventions for iron supplementation. Published by the BMJ Publishing Group Limited.

    Objective: To study the expression and clinical significance of urokinase-type plasminogen activator (uPA) in breast cancer. Methods: Applying streptavidin-biotin complex (SABC) immunohistochemical technique, expression of uPA was studied in 100 patients with primary breast cancer. Results: There were 55 patients with high uPA expression, and 45 with lower expression. There was significant correlation between uPA expression and TNM stage, lymph node status, and the tumor size. Neither age, menopausal status, nor ER status was significantly related with level of uPA expression. The patients with high expression of uPA had significantly shorter disease-free survival (DFS)and overall survival (OS) than did those with low expression of uPA. Univariate analysis showed that uPA as a prognostic factor was of similar magnitude to lymph node status and TNM stage, but stronger than that of ER status and tumor size. UPA was an independent prognostic factor affecting disease-free survival and overall survival. Conclusion: uPA appears to be a strong and independent biologic marker for predicting prognosis of breast cancer.

    Full Text Available Background: Childhood obesity is a strong predictor of adult obesity incidence and can increase risk factors for getting chronic diseases. The causes of obesity are multifactor, determined by genetic and food environment changes. Risk factors believed to be the cause of obesity are home food availability status and maternal obesity. Objective: To analyze the risk of home food availability status and maternal obesity to obesity in preschool children aged 3-5 years.  Method: This study was a matched case-control study. The case of this study was obese preschool children (Z-score WHZ > 2 SD and control of this study was non-obese preschool children (Z-score WHZ -2 ≤ SD ≤ 2. Control group was taken by an age and gender matching with the case group. Based on the nutritional status screening result of 53 early childhood education (ECD schools on 13 sub-districts in Kota Yogyakarta, there were 101 obese children and 101 non-obese children. Those schools were chosen by cluster sampling method and PPS (Probability Proportional to Size. Besides, information about home food availability status and maternal obesity was collected using questionnaire. The data were analyzed using McNemar test and conditional logistic regression.  Results: Home food availability status (OR = 1.85; p=0.03; 95% CI=1.08-3.16 and maternal obesity (OR=2.5; p=0.003; 95% CI=1.37-4.55 were the most dominant risk factor related to the incidence of obesity in preschool children aged 3-5 years. Conclusion: Home food availability status and maternal obesity significantly increase the risk for getting obese in preschool children aged 3-5 years.

    2012-01-01

    This study examined the effects of social consensus and social status on attitude certainty that is conceptualized multi-dimensionally as perceived clarity and correctness of one's attitude. In a mock opinion exchange about a social issue, participants were either supported (high consensus) or opposed (low consensus) by most of the confederates. They were informed that their opinion (high status) or their opponents' opinion (low status) had the alleged psychological significance indicative of future success. Post-experimental attitude clarity was significantly greater when attitudinal position was associated with high rather than low status. Attitude correctness was interactively affected by social status and social consensus. Supporting the compensatory effect hypothesis, attitude correctness was comparable across the levels of social consensus as long as they were associated with high status, and across the levels of social status as long as they were associated with high social consensus.

    All 115 kindergarteners in a suburban school district were evaluated with an extensive battery of intellectual, academic, social, and adaptive behavior measures to determine the predictive significance of single-parent status on school-entry competencies. Divorce was found to add significant amounts of independent variance to the socioeconomic status predictions of several criteria, specifically those relating to social and academic competence. Both single-parent status and SES were more powerful predictors than other family background, developmental history, and health variables.

    Achieving the Millennium Development Goals that aim to reduce malnutrition and child mortality depends in part on the ability of governments/policymakers to address nutritional status of children in general and those infected or affected by HIV/AIDS in particular. This study describes HIV prevalence in children, patterns of malnutrition by HIV status and determinants of nutritional status. The study involved 671 children aged 12-59 months living in the Agincourt sub-district, rural South Africa in 2007. Anthropometric measurements were taken and HIV testing with disclosure was done using two rapid tests. Z-scores were generated using WHO 2006 standards as indicators of nutritional status. Linear and logistic regression analyses were conducted to establish the determinants of child nutritional status. Prevalence of malnutrition, particularly stunting (18%), was high in the overall sample of children. HIV prevalence in this age group was 4.4% (95% CI: 2.79 to 5.97). HIV positive children had significantly poorer nutritional outcomes than their HIV negative counterparts. Besides HIV status, other significant determinants of nutritional outcomes included age of the child, birth weight, maternal age, age of household head, and area of residence. This study documents poor nutritional status among children aged 12-59 months in rural South Africa. HIV is an independent modifiable risk factor for poor nutritional outcomes and makes a significant contribution to nutritional outcomes at the individual level. Early paediatric HIV testing of exposed or at risk children, followed by appropriate health care for infected children, may improve their nutritional status and survival.

    2017-05-01

    To determine the significance of TAR DNA binding protein 43 kDa (TDP-43) pathology in amyotrophic lateral sclerosis (ALS), we examined the whole brains and spinal cords of 57 patients (35 men; 22 women; mean age 63.3 years; 15 patients with c9orf72-associated ALS [c9ALS]). TDP-43 pathologic burden was determined relative to symptom onset site, disease duration, progression rate, cognitive status, and c9ALS status. There was a trend for greater TDP-43 pathologic burden in cognitively impaired patients (p = 0.07), though no association with disease duration or progression rate was seen. Shorter disease duration (p = 0.0016), more severe striatal pathology (p = 0.0029), and a trend toward greater whole brain TDP-43 pathology (p = 0.059) were found in c9ALS. Cluster analysis identified "TDP43-limited," "TDP43-moderate," and "TDP43-severe" subgroups. The TDP43-limited group contained more cognitively intact (p = 0.005) and lower extremity onset site (p = 0.019) patients, while other subgroups contained more cognitively impaired patients. We conclude that TDP-43 pathologic burden in ALS is associated with cognitive impairment and c9ALS, but not duration of disease or rate of progression. Further, we demonstrate a subgroup of patients with low TDP-43 burden, lower extremity onset, and intact cognition, which requires further investigation. © 2017 American Association of Neuropathologists, Inc.

  5. The significance of romantic love for marriage.

    Willi, J

    1997-06-01

    In this study, 605 subjects were asked about romantic love and marriage. Married people differentiated themselves from single people with stable partners and divorced people with new partners by more frequently living together with their great love, more reciprocity in that love, and less disappointments in love relationships prior to the current relationship; but they also described themselves as less happy and satisfied than the single and divorced respondents, particularly with regard to tenderness, sex, and conversation with their partners. Independent of marital status, those who were greatly in love with their partners describe themselves as happier. Love at first sight, relative to a gradually developing love, nevertheless, did not have a worse prognosis for happiness in marriage. Being in love seems to be of greater importance for the prognosis of the marriage than marital happiness and satisfaction.

  6. On combining significances. Some trivial examples

    Krasnikov, N V

    2010-01-01

    For Poisson distribution $Pois(n, \\lambda)$ with $\\lambda \\gg 1$, $n \\gg 1$ we propose to determine significance as $S = \\frac{n_{obs}-\\lambda}{\\sqrt{\\lambda}}$. The significance $S$ coincides up to sign with often used significance. For experiments which measure the same quantities the natural but not unique rule for significance combining is $S_{comb}(S_1, S_2) = \\frac{S_1\\sigma_1+S_2\\sigma_2}{\\sqrt{\\sigma^2_1+\\sigma^2_2}}$, where $\\sigma_1$ and $\\sigma_2$ are variations. We also propose the rule for significances combining for the case with systematic errors.

    The aim of this study was to examine the prevalence of parental misperception of child weight status, and identify socioeconomic, anthropometric, behavioral and dietary factors associated with underestimation. Cross-sectional study. Data was collected in 14 Brazilian private schools. Parents of children aged 2-8 years (n=976) completed a self-reported questionnaire assessing their perception of their child's weight status, and sociodemographic, anthropometric, behavioral and dietary information. To measure the agreement between parental perception about child weight status and actual child weight status, the Kappa coefficient was estimated, and to investigate associations between parental underestimation and independent variables, chi-squared tests were performed, followed by multiple logistic regression, considering p≤0.05 for statistical significance. Overall, 48.05% of the parents incorrectly classified their child's weight. Specifically, 45.08% underestimated their child's weight status, with just 3% of parents overestimating. Children with higher body mass index (OR=2.03; p<0.001) and boys (OR=1.70; p<0.001) were more likely to have their weight status underestimated by parents. Since awareness of weight problems is essential for prevention and treatment, clinical practitioners should help parents at high risk of misperception to correctly evaluate their child's weight status.

    To describe perceptions of health status among a sample of urban minority adolescents and the contribution of demographics, intrinsic motivation, general self-efficacy, risk taking, and stressful life experiences on the adolescent's perception of health status. Correlational design. A total of 71 adolescents were studied using the Adolescent Health Chart for perceived health status, the Health Self-Determinism Index for Children, the Self-Efficacy Scale, the Risk Taking Instrument, and the Life Events Checklist. There were no statistically significant effects of demographics on perceived health status. Scores of Perceived Health Status correlated with scores of self-efficacy (r = 0.56; p perceived health status in urban minority adolescents. The results contribute to the present body of knowledge about patterns of adolescent health as perceived by the adolescent. In addition to expanding the understanding of the minority adolescent experience in relation to health promotion attributes and health compromising behaviors, the results identify antecedents that are predictive of improved perceived health status for the urban adolescent.

    Modern military operations utilize complex technologies that require high levels of readiness and sustained cognitive and physical performance of combat military combat personnel. These military operations often depend on weapon systems that use advanced computer technology coupled with an array of sensors that provide continuous information on the battlefield environment and on equipment function. However there is a lack of real-time information on status of the personnel who control these systems and who are vital to mission success. Failure of the human element renders the weapon system useless so it is important to know if an individual is physically and cognitively fit to perform his or her task. Based on the premise that status of metabolic processes provide an early indication of a change in an individuals physiological status, monitoring of selective biomarkers of metabolism and organ function can provide insight on the individual"s ability to perform mission tasks. During combat individuals may not be aware that they have reached a compromised physiological condition due to dehydration, physical exertion, stress, fatigue, sleep deprivation, exposure to toxins or other condition that may affect physical and cognitive performance and health. Systems that can provide the individual or his or her commander with information about significant changes in one or more metabolic functions could permit timely intervention to correct the condition. In the event that serious injury has already occurred to an individual, metabolic monitoring can provide valuable intelligence needed for decisions on achieving mission objectives.

  10. Predictors of subjective health status 10 years post-PCI

    2016-06-01

    Conclusions: SF-36 scores at baseline, age, and previous PCI were significant predictors of subjective health status 10 years post-PCI. Specifically, the SF-36 score at baseline was an important predictor. Thus assessment of subjective health status at baseline is useful as an indicator to predict long-term subjective health status. Subjective health status becomes better by optimal medical treatment, cardiac rehabilitation and psychosocial support. This is the first study determining predictors of subjective health status 10 years post-PCI.

    To examine the prognostic significance of lifestyle factors in urinary bladder cancer, we conducted a follow-up study of 258 incident bladder cancer patients, who were originally recruited in a case-control study in metropolitan Nagoya. Information on individual survivals was obtained from the computer data-file of the tumor registry of the Nagoya Bladder Cancer Research Group. Univariate analyses revealed significant associations of 5-year survivorship with educational attainment, marital status, drinking habits and consumption of green tea in males, and age at first consultation, histological type and grade of tumor, stage and distant metastasis in both sexes. After adjustment for age, stage, histology (histological type and grade) and distant metastasis by means of a proportional hazards model, drinking of alcoholic beverages was significantly associated with the prognosis of bladder cancer in males. Its adjusted hazard ratio was 0.46 (95% confidence interval: 0.26-0.79), favoring patients who had taken alcoholic beverages. In detailed analysis, ex-drinkers and all levels of current drinkers demonstrated hazard ratios smaller than unity, although no clear dose-response relationship was detected. No prognostic significance was found for such lifestyle factors as smoking habit, uses of artificial sweeteners and hairdye, and consumption of coffee, black tea, matcha (powdered green tea) and cola.

    Stress during pregnancy can have serious adverse outcomes on the mother, the fetus, newborn, children and even adolescents. Socioeconomic status has been recognized as a predictor of stress amongst pregnant women. The first aim of this study was to investigate the role of socioeconomic status in pregnancy stress rates. The second aim was to examine the most important items of socioeconomic status including monthly family income, husband occupational status as well as mother's educational level and their influence on the rate of maternal stress. This study was cross-sectional research and was conducted on 210 pregnant women in three trimesters of pregnancy who attended Shahryar hospital for prenatal care between August-October 2012. They completed two questionnaires of Socioeconomic Status and Specific Pregnancy Stress. Collected data were analyzed by SPSS version 19 including T-test, one-way ANOVA and Spearman correlation. In this study, we considered family income, education and husbands' occupations as the most important variables which may influence perceived stress during pregnancy. The mean age of women was 27±4.8 years. The final result showed that there is no significant relationship between SES and pregnancy stress level (P > 0.05), while we found a significant relationship, as well as indirect correlation between husbands' occupational status and pregnancy stress (P pregnancy stress levels or not.

    2015-04-01

    Exploring risk factors and profiles of intimate partner violence in other countries provides information about whether existing theories of this phenomenon hold consistent in different cultural settings. This study will present results of a regression analysis involving domestic violence among Mexican women (n = 83,159). Significant predictors of domestic violence among Mexican women included age, number of children in the household, income, education, self-esteem, family history of abuse, and controlling behavior of the husband. Women's employment status was not a significant predictor when all variables were included in the model; however, when controlling behavior of the husband was withdrawn from the model, women's employment status was a significant predictor of domestic violence toward women. Results from this research indicate that spousal controlling behavior may serve as a mediator of the predictive relationship between women's employment status and domestic violence among Mexican women. Findings provide support for continued exploration of the factors that mediate experiences of domestic violence among women worldwide.

    Iron is considered a nutrient of concern for vegetarians. In children, inadequate iron status may lead to anemia and poor growth. Thirteen original manuscripts met the inclusion criteria. Various biochemical markers of iron status, such as hemoglobin (Hb) and serum ferritin, were used. Seven of the 13 studies reported the prevalence of iron deficiency separately for vegetarians and non-vegetarians. Five out of 7 showed a higher prevalence of iron deficiency among the vegetarian participants, while the other 2 showed a higher prevalence of iron deficiency among non-vegetarians. A wide range of iron deficiency prevalence, from 4.3% of vegetarian participants in one study to 73% having ferritin vegetarian children varies considerably from one study to another. The wide variation in the prevalence of inadequate iron status was consistent for studies from industrial and developing countries. The physiological significance of low iron status among vegetarians reported in some studies is unknown. © 2017 S. Karger AG, Basel.

    Barbiturate anesthesia, which is commonly used for refractory status epilepticus, is an effective treatment, but with many significant complications. The relationship between the duration of this extreme therapy and the ultimate outcome of refractory status epilepticus has not been well studied. We report a 7-year-old girl who presented with refractory status epilepticus secondary to presumed encephalitis with a focal lesion on cranial magnetic resonance imaging. She was treated for 70 days with high-dose antiepileptic drugs and recovered with a residual seizure disorder. This case suggests that, if the status epilepticus is due to a reversible cause such as encephalitis, neurologic recovery may occur despite this very prolonged course of extreme therapy.

    The present study attempts to investigate the impact of protein energy malnutrition (PEM) on chromosomes. Twenty infants suffering from marasmus and kwashiorkor were chosen from the in-patient paediatric hospital of Ain Shams University. They were matched by age and sex and socioeconomic status to ten healthy infants (controls). Whole blood lymphocytic cultures were set up for every infant and harvested after 48 h incubation. The frequency of chromosomal aberrations was found to be nearly nine times greater among infants with PEM compared to controls (6.7% versus 0.7% respectively); the difference was statistically highly significant, P less than 0.001. The recorded aberrations were mainly chromatid gaps and isogaps. In addition, chromatid breaks, dicentrics and acentric fragments were observed. Moreover, the younger the age of the infant the greater the frequency of chromosomal aberrations. The results direct our attention to the genetic risk effect of PEM.

  12. Public health significance of elevated homocysteine.

    Science.gov (United States)

    Selhub, Jacob

    2008-06-01

    Homocysteine is a sulfur amino acid whose metabolism stands at the intersection of two pathways: remethylation, which requires folic acid and vitamin B12 coenzymes; and transsulfuration, which requires pyridoxal-5'-phosphate, the vitamin B6 coenzyme. Data from a number of laboratories suggest that mild elevations of homocysteine in plasma are a risk factor for occlusive vascular disease. In the Framingham studies, we have shown that plasma homocysteine concentration is inversely related to the intake and plasma levels of folate and vitamin B6 as well as vitamin B12 plasma levels. Almost two-thirds of the prevalence of high homocysteine is attributable to low vitamin status or intake. Elevated homocysteine concentrations in plasma are a risk factor for prevalence of extracranial carotid-artery stenosis > or = 25% in both men and women. Prospectively elevated plasma homocysteine is associated with increased total and cardiovascular mortality, increased incidence of stroke, increased incidence of dementia and Alzheimer's disease, increased incidence of bone fracture, and higher prevalence of chronic heart failure. It was also shown that elevated plasma homocysteine is a risk factor for preeclampsia and maybe neural tube defects (NTD). This multitude of relationships between elevated plasma homocysteine and diseases that afflict the elderly, pregnant women, and the embryo points to the existence ofa common denominator which may be responsible for these diseases. Whether this denominator is homocysteine itself or homocysteine is merely a marker, remains to be determined.

    Full Text Available SUMMARY The concern about the maintenance of the human species has existed since the earliest civilizations. Progress in the diagnosis and treatment of infertility has led to the development of assisted reproductive techniques (ART which, along with the evolution of genetics and molecular biology studies, have contributed in a concrete way to the management of infertile couples. Classic in vitro fertilization was initially developed 35 years ago for the treatment of women with tubal blockage, however, it remains inaccessible to a significant proportion of infertile couples around the world. This can be explained by the lack of specialized clinics in some countries and by the high cost of the procedures. Efforts have been employed to increase the number of treatment cycles for assisted reproduction, as for example, the creation of low-cost programs. Even today, infertility remains a problem of global proportions, affecting millions of couples. The estimate of the incidence of infertility is uncertain, mainly because of the criteria used for its definition. This article aims to review the most important aspects, succinctly, regarding the incidence, etiology, and treatment options available to infertile couples.

  14. The RHIC status update

    The construction of the Relativistic Heavy Ion Collider (RHIC) began in 1991, with the completion date originally scheduled for 1997. Significant reduction of the funding levels in FY 1993 and 1994, and the funding level cap for FY 1995 and later years caused a 19-month stretchout of the construction period to the second quarter of FY 1999, and an increase of the total estimated cost (TEC) to $475 M. The Project, therefore, is now at the halfway mark of the construction period with actual cost and schedule performance tracking close to the DOE-approved baseline. Construction funding through FY 1994 reached close to 60% of the TEC. Incidentally, if one adds the current value of preexisting facilities which will be incorporated into RHIC, such as the injection system (Tandem Van de Graaff - the Booster - the AGS), the esixting 3.8 km tunnel, the 24 kW helium refrigerator, etc., the total value of the RHIC facility, when completed, will reach one billion dollars, if not more. The accelerator lattice design was finalized in 1992 after an intensive study was made to optimize the collider design for performance, operational flexibility, and value engineering. The civil construciton, including the collider enclosure, magnet access ports to the ring tunnel, and six service buildings for accelerator power supplies and cryogenic control boxes was completed.

    The Federal Housing Finance Agency (FHFA) regulates Fannie Mae, Freddie Mac, and the 12 Federal Home Loan Banks (the government-sponsored enterprises - GSEs). On July 6, 2010, FHFA and the Office of the Comptroller of the Currency (OCC) concluded that Property Assessed Clean Energy (PACE) programs 'present significant safety and soundness concerns' to the housing finance industry. This statement came after a year of discussions with state and federal agencies in which PACE, a novel mechanism for financing energy efficiency and renewable energy improvements, has gone from receiving support from the White House, canonization as one of Scientific American's 'World Changing Ideas' and legislative adoption in 24 states to questionable relevance, at least in the residential sector. Whether PACE resumes its expansion as an innovative tool for financing energy efficiency and clean generation depends on outcomes in each of the three branches of government - discussions on a PACE pilot phase among federal agencies, litigation in federal court, and legislation in Congress - all highly uncertain. This policy brief addresses the practical impacts of these possible outcomes on existing and emerging PACE programs across the United States and potential paths forward.

    Survival from male breast cancer is influenced by many factors. This study assessed payer's status effect on survival of male breast cancer patients. This study included 8,828 male breast cancer patients diagnosed between 1998-2006 and followed to 2011 in the National Cancer Data Base. Cox regression was used to investigate the effect of payer's status and other factors on overall survival. Patients had 36.2%, 42.7%, 14.7%, and 6.5% of stage I to IV cancer, respectively. Payer status was private 47.7%, Medicare 42.6%, Medicaid 3.24%, unknown 3.59%, and uninsured 2.95%. Median overall survival (MOS) for all patients was 10.6 years. In multivariate analysis, Direct adjusted MOS was 12.46, 11.89, 9.99, 9.02, and 8.29 years for private, "unknown," Medicare, uninsured, and Medicaid payer's status, respectively. Patients with private and "unknown" payer's status showed a significant difference in survival compared to uninsured patients, while Medicaid and Medicare patients did not. Age, race, stage, grade, income, comorbidity, distance travelled, and diagnosing/treating facility were also significant predictors of survival. Treatment delay and cancer program did not have a significant influence on survival. © 2015 Wiley Periodicals, Inc.

    A suggested relationship between selenium (Se) status and sex hormones is based on sex-linked differences in Se status of the liver and dramatic changes in Se status during pregnancy. The effect of estrous cycle hormone fluctuation on Se status was studied in the chronically-catheterized rat model. Se status, measured as plasma and RBC Se and glutathione peroxidase activity (GPx), was assessed at each stage of the 4-day estrous cycle. Stages, determined by cytological exam of vaginal smears, were estrus (E), metestrus (ME), diestrus (DE), and proestrus (PE). Five rats fed a 0.1 ppm Se diet, were catheterized at the abdominal aorta, allowing serial blood draws under nonstressful conditions. At least three blood samples per rat were collected daily for two consecutive cycles. Plasma Se during PE was significantly greater than that at E, ME, or DE. Peak plasma Se occurred at 1,000 hr PE. Peak estrogen and progesterone levels have been reported to occur later in PE. Peak plasma occurred during ME and early PE. A significant decrease in plasma GPx during late PE corresponds with reported peaks in estrogen and progesterone. There were no significant differences in RBC Se or GPx during the estrous cycle. The results of this study suggest that changes in plasma Se and GPx during the estrous cycle may precede similar fluctuations in estrogen and progesterone.

    Riviello, James J; Holmes, Gregory L

    2004-06-01

    Status epilepticus (SE) is a life-threatening emergency that requires prompt treatment, including basic neuroresuscitation principles (the ABCs), antiepileptic drugs to stop the seizure, and identification of etiology. Symptomatic SE is more common in younger children. Treating the precipitating cause may prevent ongoing neurologic injury and facilitates seizure control. A systematic treatment regimen, planned in advance, is needed, including one for refractory status epilepticus (RSE). Here we emphasize definitions, clinical and electroencephalography stages, early treatment, special circumstances that may require immediate seizure control, and treatment of RSE. Because much clinical research in SE has been done in adults, we indicate the patient population studied.

This article makes use of sense-making theory to explore how sense-making among EA researchers and practitioners influence significance determination. Focus is on the situation when persons have their first look at information...... about a strategic choice and as part of this make their initial judgement of significance. An experiment is designed and conducted to investigate how persons make sense of a specific case and determine significance in a screening and scoping context. The experiment indicates patterns in the test persons......' sense-making, including important differences in the way individuals screen and scope. These patterns concern what we notice, how fast we frame the choice, and when we are critical about the provided information.

  7. Significant communities in large sparse networks

    Mirshahvalad, Atieh; Derlen, Mattias; Rosvall, Martin

    2011-01-01

    Researchers use community-detection algorithms to reveal large-scale organization in biological and social networks, but community detection is useful only if the communities are significant and not a result of noisy data. To assess the statistical significance of the network communities, or the robustness of the detected structure, one approach is to perturb the network structure by removing links and measure how much the communities change. However, perturbing sparse networks is challenging because they are inherently sensitive; they shatter easily if links are removed. Here we propose a simple method to perturb sparse networks and assess the significance of their communities. We generate resampled networks by adding extra links based on local information, then we aggregate the information from multiple resampled networks to find a coarse-grained description of significant clusters. In addition to testing our method on benchmark networks, we use our method on the sparse network of the European Court of Just...

    2014-03-01

    Faculty who want to energize graduate students with creative classes that lead to long-lasting learning will benefit by designing course objectives, learning activities, and assessment tools using Fink's taxonomy of significant learning and Wiggins's insights on performance-based or educative assessments. Research shows that course designs relying on content-driven lectures and written examinations do not promote significant learning among adult learners. This article reviews six types of significant learning using Fink's taxonomy and examines Wiggins's "backward" approach to designing courses using performance-based assessments that gauge true learning and learning that promotes a lasting change. When designing courses, educators should ask: "What do I really want students to get out of this course?" The answers will direct the design of objectives, learning activities, and assessment tools. Designing graduate courses using Fink's taxonomy and Wiggins's backward approach can lead to significant learning to better prepare nurse practitioners for the future of health care.

  11. [Current status of autism studies].

    Science.gov (United States)

    Kurita, H

    2001-01-01

    The current status of autism studies was reviewed based on English articles published during the 1990s. Although the concepts of autism and pervasive developmental disorders (PDD) are established, diagnostic criteria of PDDNOS or atypical autism, which is frequently difficult to differentiate from autism, need to be established. The prevalence of autism has been estimated as about 0.05% in the U.S and many European countries, while it was reported to be 0.1% or higher in Japan and some European countries, though the reasons for this difference are unclear. High-functioning (IQ > or = 70) autism may not be as rare a condition as previously thought and both its difference from and similarity to Asperger's syndrome, the highest functioning PDD subtype, need clarification. About 20 to 40% of children with autism lose meaningful words by the age of 2 years and display autistic symptoms thereafter. Such autism, called the setback type in Japan, has been demonstrated to have a poorer adolescent/adult outcome compared to autism without setback and its relationship with childhood disintegrative disorder, which displays a clearer regression after normal development for at least the first 2 years of life, needs to be addressed. The etiology of autism is now considered mostly genetic for reasons, such as the significantly higher concordance rate of autism in identical twin pairs (60-80%) than in fraternal twin pairs (0-10%) and an 3-5% incidence of autism among sibs of an autism proband, 30 to 100 times higher than that in the general population. The involvement of several genes is implicated to create susceptibility for autism, yet the responsible genes have not been identified. Although there is no medication to cure autism, some psychotropic drugs, such as antipsychotics and SSRIs, seem effective for behavior problems in autism patients. Psychosocial treatments are the main therapeutic approach to autism, though they are yet to be well systematized. It is important to

    It is still debated whether alien plants benefit from being mycorrhizal, or if engaging in the symbiosis constrains their establishment and spread in new regions. We analyzed the association between mycorrhizal status of alien plant species in Germany and their invasion success. We compared whether the representation of species with different mycorrhizal status (obligate, facultative, or non-mycorrhizal) differed at several stages of the invasion process. We used generalized linear models to explain the occupied geographical range of alien plants, incorporating interactions of mycorrhizal status with plant traits related to morphology, reproduction, and life-history. Non-naturalized aliens did not differ from naturalized aliens in the relative frequency of different mycorrhizal status categories. Mycorrhizal status significantly explained the occupied range of alien plants; with facultative mycorrhizal species inhabiting a larger range than non-mycorrhizal aliens and obligate mycorrhizal plant species taking an intermediate position. Aliens with storage organs, shoot metamorphoses, or specialized structures promoting vegetative dispersal occupied a larger range when being facultative mycorrhizal. We conclude that being mycorrhizal is important for the persistence of aliens in Germany and constitutes an advantage compared to being non-mycorrhizal. Being facultative mycorrhizal seems to be especially advantageous for successful spread, as the flexibility of this mycorrhizal status may enable plants to use a broader set of ecological strategies.

    The literature on colorectal cancer (CRC screening is contradictory regarding the impact of weight status on CRC screening. This study was intended to determine if CRC screening rates among 2005 National Health Interview Survey (NHIS respondent racial/ethnic and gender subgroups were influenced by weight status. Methods. Univariable and multivariable logistic regression analyses were performed to determine if CRC screening use differed significantly among obese, overweight, and normal-weight individuals in race/ethnic and gender subgroups. Results. Multivariable analyses showed that CRC screening rates did not differ significantly for individuals within these subgroups who were obese or overweight as compared to their normal-weight peers. Conclusion. Weight status does not contribute to disparities in CRC screening in race/ethnicity and gender subgroups.

  15. Innovative trend significance test and applications

    2017-02-01

    Hydro-climatological time series might embed characteristics of past changes concerning climate variability in terms of shifts, cyclic fluctuations, and more significantly in the form of trends. Identification of such features from the available records is one of the prime tasks of hydrologists, climatologists, applied statisticians, or experts in related topics. Although there are different trend identification and significance tests in the literature, they require restrictive assumptions, which may not be existent in the structure of hydro-climatological time series. In this paper, a method is suggested with statistical significance test for trend identification in an innovative manner. This method has non-parametric basis without any restrictive assumption, and its application is rather simple with the concept of sub-series comparisons that are extracted from the main time series. The method provides privilege for selection of sub-temporal half periods for the comparison and, finally, generates trend on objective and quantitative manners. The necessary statistical equations are derived for innovative trend identification and statistical significance test application. The application of the proposed methodology is suggested for three time series from different parts of the world including Southern New Jersey annual temperature, Danube River annual discharge, and Tigris River Diyarbakir meteorology station annual total rainfall records. Each record has significant trend with increasing type in the New Jersey case, whereas in other two cases, decreasing trends exist.

  16. Meaning reconstruction in bereavement: sense and significance.

    Hibberd, Rachel

    2013-08-01

    Recently there has been growing empirical and theoretical attention to the role of meaning in grief along with increased recognition of the need for more sophisticated definitions of meaning. The present article highlights philosophical issues inherent in the study of meaning and grief reviews the place of meaning in current theories of grief and provides a brief overview of the ways that meaning has been operationalized by grief researchers, including sense-making, benefit finding, identity change, and purpose in life. It is argued that, in our focus on the ways mourners make sense of loss, we have neglected an important aspect of meaning: life significance. Life significance is the felt perception that some aspect of one's life experience "matters." The construct is explored as a potentially important outcome of bereavement; mourners may lose life significance along with their lost loved one, or they may develop new avenues to life significance as they confront mortality and rebuild shattered worldviews. Related literature, such as appreciation of life as a facet of posttraumatic growth, is surveyed for clues as to the role of life significance in grief. Suggestions for future study are offered.

  1. Statistical significance of cis-regulatory modules

    Smith Andrew D

    2007-01-01

    Full Text Available Abstract Background It is becoming increasingly important for researchers to be able to scan through large genomic regions for transcription factor binding sites or clusters of binding sites forming cis-regulatory modules. Correspondingly, there has been a push to develop algorithms for the rapid detection and assessment of cis-regulatory modules. While various algorithms for this purpose have been introduced, most are not well suited for rapid, genome scale scanning. Results We introduce methods designed for the detection and statistical evaluation of cis-regulatory modules, modeled as either clusters of individual binding sites or as combinations of sites with constrained organization. In order to determine the statistical significance of module sites, we first need a method to determine the statistical significance of single transcription factor binding site matches. We introduce a straightforward method of estimating the statistical significance of single site matches using a database of known promoters to produce data structures that can be used to estimate p-values for binding site matches. We next introduce a technique to calculate the statistical significance of the arrangement of binding sites within a module using a max-gap model. If the module scanned for has defined organizational parameters, the probability of the module is corrected to account for organizational constraints. The statistical significance of single site matches and the architecture of sites within the module can be combined to provide an overall estimation of statistical significance of cis-regulatory module sites. Conclusion The methods introduced in this paper allow for the detection and statistical evaluation of single transcription factor binding sites and cis-regulatory modules. The features described are implemented in the Search Tool for Occurrences of Regulatory Motifs (STORM and MODSTORM software.

    2011-04-01

    There is lack of consensus on the best method of functional assessment, and there is a paucity of studies on daily functioning in centenarians. We sought to compare associations between performance-based, self-report, and proxy report of functional status in centenarians. We expected the strongest relationships between proxy reports and observed performance of basic activities of daily living (BADLs) and instrumental activities of daily living (IADLs). We hypothesized that the discrepancy between self-report and observed daily functioning would be modified by cognitive status. We additionally sought to provide clinicians with estimates of centenarians' observed daily functioning based on their mental status in combination with subjective measures of activities of daily living (ADLs). Two hundred and forty-four centenarians from the Georgia Centenarian Study were included in this cross-sectional population-based study. Measures included the Direct Assessment of Functional Status, self-report and proxy report of functional status, and the Mini-Mental State Examination (MMSE). Associations between observed and proxy reports were stronger than between observed and self-report across BADL and IADL measures. A significant MMSE by type of report interaction was found, indicating that lower MMSE performance is associated with a greater discrepancy between subjective and objective ADL measures. Results demonstrate associations between 3 methods of assessing functional status and suggest proxy reports are generally more accurate than self-report measures. Cognitive status accounted for some of the discrepancy between observed and self-reports, and we provide clinicians with tables to estimate centenarians' performance on observed functional measures based on MMSE and subjective report of functional status.

    This study examined the association between having been bullied at school during the past 6 months ("bullied status") and not meeting physical activity (PA) recommendations of 60 minutes of daily PA during the past week among 8th- and 11th-grade Texas adolescents. Multiple logistic regression analysis was conducted to examine this association, adjusted for weight status, grade, race/ethnicity, and stratified by gender; furthermore, a significant interaction was found between bullied status and weight status. Results are presented by interaction status. Results indicated that overweight girls who reported never being bullied, as well as those who reported being bullied more than twice, had higher odds of not meeting PA recommendations than normal weight girls who were never bullied (adjusted odds ratio [AOR] = 2.12, 95% confidence interval [CI: 1.12, 3.99]; AOR = 9.18, 95% CI [2.26, 37.27], respectively). Obese girls who were bullied once or twice had higher odds of not meeting PA recommendations than normal weight girls who were never bullied (AOR = 2.89, 95% CI [1.06, 7.89]). Overweight boys who reported never being bullied had lower odds of not meeting PA recommendations than normal weight boys who were never bullied (AOR = 0.62, 95% CI [0.39, 0.97]). Conversely, obese boys who were bullied once or twice reported higher odds of not meeting PA recommendations than normal weight boys who were never bullied (AOR = 3.61, 95% CI [1.22, 10.67]). Findings from this study indicate that the association between bullied status and meeting PA recommendations is complex and may differ by gender and the interaction between bullied status and weight status.

    Aquaporins are membrane integral proteins responsible for the transmembrane transport of water and other small neutral molecules. Despite their well-acknowledged importance in water transport, their significance in gas transport processes remains unclear. Growing evidence points to the involvement of plant aquaporins in CO2 delivery for photosynthesis. The role of these channel proteins in the transport of O2 and other gases may also be more important than previously envisioned. In this study, we examined O2 permeability of various human, plant, and fungal aquaporins by co-expressing heterologous aquaporin and myoglobin in yeast. Two of the most promising O2-transporters (Homo sapiens AQP1 and Nicotiana tabacum PIP1;3) were confirmed to facilitate O2 transport in the spectrophotometric assay using yeast protoplasts. The over-expression of NtPIP1;3 in yeasts significantly increased their O2 uptake rates in suspension culture. In N. tabacum roots subjected to hypoxic hydroponic conditions, the transcript levels of the O2-transporting aquaporin NtPIP1;3 significantly increased after the seven-day hypoxia treatment, which was accompanied by the increase of ATP levels in the apical root segments. Our results suggest that the functional significance of aquaporin-mediated O2 transport and the possibility of controlling the rate of transmembrane O2 transport should be further explored.

    Community structure analysis is a powerful tool for social networks that can simplify their topological and functional analysis considerably. However, since community detection methods have random factors and real social networks obtained from complex systems always contain error edges, evaluating the significance of a partitioned community structure is an urgent and important question. In this paper, integrating the specific characteristics of real society, we present a framework to analyze the significance of a social community. The dynamics of social interactions are modeled by identifying social leaders and corresponding hierarchical structures. Instead of a direct comparison with the average outcome of a random model, we compute the similarity of a given node with the leader by the number of common neighbors. To determine the membership vector, an efficient community detection algorithm is proposed based on the position of the nodes and their corresponding leaders. Then, using a log-likelihood score, the tightness of the community can be derived. Based on the distribution of community tightness, we establish a connection between p-value theory and network analysis, and then we obtain a significance measure of statistical form . Finally, the framework is applied to both benchmark networks and real social networks. Experimental results show that our work can be used in many fields, such as determining the optimal number of communities, analyzing the social significance of a given community, comparing the performance among various algorithms, etc.

  9. Significance tests and sample homogeneity loophole

    Kupczynski, Marian

    2015-01-01

    In their recent comment, published in Nature, Jeffrey T.Leek and Roger D.Peng discuss how P-values are widely abused in null hypothesis significance testing . We agree completely with them and in this short comment we discuss the importance of sample homogeneity tests. No matter with how much scrutiny data are gathered if homogeneity tests are not performed the significance tests suffer from sample homogeneity loophole and the results may not be trusted. For example sample homogeneity loophole was not closed in the experiment testing local realism in which a significant violation of Eberhard inequality was found. We are not surprised that Bell type inequalities are violated since if the contextual character of quantum observables is properly taken into account these inequalities cannot be proven. However in order to trust the significance of the violation sample homogeneity loophole must be closed. Therefore we repeat after Jeffrey T.Leek and Roger D.Peng that sample homogeneity loophole is probably just the ...

    Full Text Available A survey was conducted in Novi Sad in the preschool institutions of 'Radosno detinjstvo' on a sample of 423 preschool children of both sexes, ages 6 and 7. The subject of this paper are postural disorders on the spinal column in the sagittal and frontal planes, as well as foot deformities. The aim of the research is to determine the frequency of disorder of postural status of the spine (kyphosis, lordosis and scoliosis and deviation from the normal status of the foot, and the analysis of the differences between boys and girls. Assessment of the postural status of the feet was performed by means of using the Pedikom computer system for digital computerised pedography. Assessment of spine postural status was done by means of SpineScan portable device. Data were analysed according to the frequency for the assessment of spinal status, the status of the foot, all according gender. Significance of the gender-conditioned differences was determined by the Chi-square test. The results indicate that in the examined population, the most common posture is lordotic bad posture, 41.31% with male examinees and 36.66% with female examinees. A statistically significant difference in relation to sexual dimorphism was found for the parameter of scoliotic bad posture (Sig. = 0.008. In terms of deviation from the normal status of the feet, in the examined population, pronating foot level I accounts for 43.23%, pronating foot level II accounts for 16.66% and high-arched foot accounts for 10.16%. Quantitative results indicate the need for corrective gymnastic to correct but also prevent postural deformities by introducing of the same as an everyday directed activity of preschool population.

    2015-09-01

    Full Text Available Counterfeit drugs have emerged as a major global problem. This issue has been brought to the centre of the Indian media due to the death of 15 women attending a sterilization camp in Chhattisgarh. India's pharmaceutical industry exports drugs worth 15 billion dollars, which means a high prevalence of counterfeiting in India's drug industry has global repercussions. However, accurate figures on the extent of counterfeit drugs in India are not available. The scientific literature as well as media reports often quotes figures of 10-35%, though studies done by the Indian Government dispute this. Counterfeit drug numbers have been known to be under represented by Governments due to fear of undermining their economy and health systems. On the other hand, rival companies in other countries may have an incentive to over hype India's counterfeit problem to dent India's growing status as the leading global supplier of generic medicines. Lack of clear definitions and differences between laws of countries further complicate reporting. A high prevalence of counterfeit drugs has a large impact on both health and economic indicators. Additionally, counterfeit drugs provide significant challenges to Pharmacovigilance programmes. Hence, here we discuss the significance of use of counterfeit drugs in India and challenges faced by Pharmacovigilance due to the extensive use of counterfeit drugs.

    2011-01-01

    With the recent detection of over 500 extrasolar planets, the existence of "other worlds", perhaps even other Earths, is no longer in the realm of science fiction. The study of exoplanets rapidly moved from an activity on the fringe of astronomy to one of the highest priorities of the world's astronomical programs. Actual images of extrasolar planets were revealed over the past two years for the first time. NASA's Hubble Space Telescope is already characterizing the atmospheres of Jupiter-like planets, in other systems. And the recent launch of the NASA Kepler space telescope is enabling the first statistical assessment of how common solar systems like our own really are. As we begin to characterize these "other worlds" and assess their habitability, the question of the significance and uniqueness of life on Earth will impact our society as never before. I will provide a comprehensive overview of the techniques and status of exoplanet detection, followed by reflections as to the societal impact of finding out that Earths are common, or rare. Will finding other potentially habitable planets create another "Copernican Revolution"? Will perceptions of the significance of life on Earth change when we find other Earth-like planets? I will discuss the plans of the scientific community for future telescopes that will be abe to survey our solar neighborhood for Earth-like planets, study their atmospheres, and search for biological signs of life.

  5. Potential Significance of the EU Water Framework Directive to China

    2009-01-01

    The European Union Water Framework Directive (EU WFD) is a unique piece of legislation, which may be of great significance to on - going reforms of the water sector in China. First and foremost it unites 27 European mem- ber states behind a common goal, which is "to achieve good chemical and ecological status" of all water bodies across the EU. Other significant characteristics of the EU WFD are that (1) it sets a clear timeframe with a number of time - bound actions for member states to achieve the goal, hut leaves it to member states to achieve this goal in a decent- ralised process, which makes allowance for the different socio - economic conditions, (2) it defines the river basin as the management unit for water thus departing with the traditional fragmented management by administrative units and it appoints a single competent authority for water management within each fiver basin, thus facilitating resolution of sector conflicts, (3) it requires a financial and economic analysis of the costs of implementing the EU WFD to enable deci- sion makers to assess whether the required improvements are affordable to government and to the population within the fiver basin, and (4) it requires a structured process for information and consultation with stakeholders and the public throughout the planning and implementation process.

    This study was designed to assess the effect of particular tools on the nutritional status of patients with stroke risk factors; to analyze these risk factors; to construct an assessment table; and to enable nurses to conduct fast and accurate assessment of the nutritional status of patients with stroke. Various nutritional assessment tools were employed to assess the nutritional status of stroke patients [(Nutritional Risk Screening 2002, NRS2002); (mini nutritional assessment, MNA), (subjective global assessment SGA), (malnutrition universal screening, MUST); (body composition, BCA)]. The leading disease-related factors of cerebral apoplexy were observed in patients with malnutrition. And a statistical analysis was conducted. The significant risk factors of cerebral apoplexy in malnourished patients older than 70 years were swallowing dysfunctions, disturbance of consciousness and reliance or half-reliance on feeding practices. The significant risk factors of malnutrition in patients with cerebral apoplexy were the decline in upper limb muscle strength, decline in the performance of various activities, loss of appetite and gastrointestinal symptoms. Disorders that affect the nutritional status of stroke patients can be used as evaluation tools, as described in the evaluation table. The clinical relevance of this study includes the following: to enable the clinical nursing staff to easily assess the patient's nutritional status in a timely manner; to improve compliance with nutritional evaluation; to provide clinical nutrition support to patients with stroke; and to provide a scientific basis for the improvement of the clinical outcomes of patients with cerebral apoplexy.

    The traditional assumption that children's nutritional deficiencies are essentially due either to overall food scarcity or to a lack of family resources to purchase available food has been increasingly questioned. Parental characteristics represent 1 type of noneconomic factor that may be related to variability in children's diets and nutritional status. We report evidence on the relation of 2 parental characteristics, maternal education level and maternal intelligence, to infant and toddler diet and nutritional status. Our sample consisted of 241 low-income Peruvian mothers and their infants assessed from 3 to 12 mo, with a further follow-up of 104 of these infants at 18 mo of age. Using a nonexperimental design, we related measures of level of maternal education, maternal intelligence, and family socioeconomic status to infant anthropometry, duration of exclusive breast-feeding, adequacy of dietary intake, and iron status. Results indicated unique positive relations between maternal education level and the extent of exclusive breast-feeding. Significant relations between maternal education and offspring length were partially mediated by maternal height. There also were unique positive relations between maternal intelligence and quality of offspring diet and hemoglobin level. All findings remained significant even after controlling for family socioeconomic characteristics. This pattern of results illustrates the importance of parental characteristics in structuring the adequacy of offspring diet. Maternal education and intelligence appear to have unique influences upon different aspects of the diet and nutritional status of offspring.

  9. Adjusting Population Risk for Functional Health Status.

    Fuller, Richard L; Hughes, John S; Goldfield, Norbert I

    2016-04-01

    Risk adjustment accounts for differences in population mix by reducing the likelihood of enrollee selection by managed care plans and providing a correction to otherwise biased reporting of provider or plan performance. Functional health status is not routinely included within risk-adjustment methods, but is believed by many to be a significant enhancement to risk adjustment for complex enrollees and patients. In this analysis a standardized measure of functional health was created using 3 different source functional assessment instruments submitted to the Medicare program on condition of payment. The authors use a 5% development sample of Medicare claims from 2006 and 2007, including functional health assessments, and develop a model of functional health classification comprising 9 groups defined by the interaction of self-care, mobility, incontinence, and cognitive impairment. The 9 functional groups were used to augment Clinical Risk Groups, a diagnosis-based patient classification system, and when using a validation set of 100% of Medicare data for 2010 and 2011, this study found the use of the functional health module to improve the fit of observed enrollee cost, measured by the R(2) statistic, by 5% across all Medicare enrollees. The authors observed complex nonlinear interactions across functional health domains when constructing the model and caution that functional health status needs careful handling when used for risk adjustment. The addition of functional health status within existing risk-adjustment models has the potential to improve equitable resource allocation in the financing of care costs for more complex enrollees if handled appropriately.

    We have cross matched the Gaia Data Release 1 secondary dataset that contains positions of 1.14 billion objects against the most complete to date catalogue of VLBI positions of 11.4 thousand sources, almost exclusively active galactic nuclei. We found 6,064 matches, i.e. 53% radio objects. The median uncertainty of VLBI positions is a factor of 4 smaller than the median uncertainties of their optical counterparts. Our analysis shows that the distribution of normalized arc lengths significantly deviates from Rayleighian shape with an excess of objects with small normalized arc lengths and with a number of outliers. We found that 8% matches have radio optical offsets significant at 99% confidence level. Therefore, we conclude there exists a population of objects with genuine offsets between centroids of radio and optical emission.

    Traditionally primary irradiation creep is introduced into graphite analysis by applying the appropriate amount of creep strain to the model at the initial time-step. This is valid for graphite components that are subjected to high fast neutron flux fields and constant stress fields, but it does not allow for the effect of movement of stress locations around a graphite component during life, nor does it allow primary creep to be applied rate-dependently to graphite components subject to lower fast neutron flux. This paper shows that a differential form of primary irradiation creep in graphite combined with the secondary creep formulation proposed by Kennedy et al. performs well when predicting creep behaviour in experimental samples. The significance of primary irradiation creep in particular in regions with lower flux is investigated. It is shown that in low flux regions with a realistic operating lifetime primary irradiation creep is significant and is larger than secondary irradiation creep.

  18. Cross wavelet analysis: significance testing and pitfalls

    2004-01-01

    Full Text Available In this paper, we present a detailed evaluation of cross wavelet analysis of bivariate time series. We develop a statistical test for zero wavelet coherency based on Monte Carlo simulations. If at least one of the two processes considered is Gaussian white noise, an approximative formula for the critical value can be utilized. In a second part, typical pitfalls of wavelet cross spectra and wavelet coherency are discussed. The wavelet cross spectrum appears to be not suitable for significance testing the interrelation between two processes. Instead, one should rather apply wavelet coherency. Furthermore we investigate problems due to multiple testing. Based on these results, we show that coherency between ENSO and NAO is an artefact for most of the time from 1900 to 1995. However, during a distinct period from around 1920 to 1940, significant coherency between the two phenomena occurs.

    Neuroplasticity is an important property of the neural system controlling breathing. However, our appreciation for its importance is still relatively new, and we have much to learn concerning different forms of plasticity, their underlying mechanisms, and their biological and clinical significance. In this brief review, we discuss several well-studied models of respiratory plasticity, including plasticity initiated by inactivity in the respiratory system, intermittent and sustained hypoxia, and traumatic injury to the spinal cord. Other aspects of respiratory plasticity are considered in other contributions to this special edition of Experimental Neurology on respiratory plasticity. Finally, we conclude with discussions concerning the biological and clinical significance of respiratory motor plasticity, and areas in need of future research effort.

    2011-02-01

    Full Text Available Abstract Truth claims in the medical literature rely heavily on statistical significance testing. Unfortunately, most physicians misunderstand the underlying probabilistic logic of significance tests and consequently often misinterpret their results. This near-universal misunderstanding is highlighted by means of a simple quiz which we administered to 246 physicians at two major academic hospitals, on which the proportion of incorrect responses exceeded 90%. A solid understanding of the fundamental concepts of probability theory is becoming essential to the rational interpretation of medical information. This essay provides a technically sound review of these concepts that is accessible to a medical audience. We also briefly review the debate in the cognitive sciences regarding physicians' aptitude for probabilistic inference.

  2. Evaluative meaning and its cultural significance

    OpenAIRE

    Drazdauskiene, Maria Liudvika

    2008-01-01

    In the framework of traditional descriptive semantics, evaluative meaning is defined as an aspect of affective meaning. By virtue of its general positive and negative evaluation, evaluative meaning finds its place in the compartment of interpersonal meaning in functional linguistics. The concept of evaluative meaning is also in agreement with the categorisation of meaning in contemporary stylistics. Having stated its spread and disagreement with logic, the cultural significance of...

    Full Text Available Among the many factors that contribute to bacterial colonization, persistence and development of infection, the ability of microorganisms to form small colony variants (SCVs assumes great significance. Although bacteria require intrinsic virulence factors to cause pathogenesis, some of them regularly evolve mechanisms to evade immune mechanisms, become resistant to antibiotics, and sustain in the human/animal cells to cause chronic infections. This mini review highlights the recent advances in the study of SCVs.

    Transfer functions are valuable tools in palaeoecology, but their output may not always be meaningful. A recently-developed statistical test ('randomTF') offers the potential to distinguish among reconstructions which are more likely to be useful, and those less so. We applied this test to a large number of reconstructions of peatland water table depth based on testate amoebae. Contrary to our expectations, a substantial majority (25 of 30) of these reconstructions gave non-significant results (P > 0.05). The underlying reasons for this outcome are unclear. We found no significant correlation between randomTF P-value and transfer function performance, the properties of the training set and reconstruction, or measures of transfer function fit. These results give cause for concern but we believe it would be extremely premature to discount the results of non-significant reconstructions. We stress the need for more critical assessment of transfer function output, replication of results and ecologically-informed interpretation of palaeoecological data.

  5. Characteristics, dynamics and significance of marine snow

    Science.gov (United States)

    Alldredge, Alice L.; Silver, Mary W.

    Macroscopic aggregates of detritus, living organisms and inorganic matter known as marine snow, have significance in the ocean both as unique, partially isolated microenvironments and as transport agents: much of surface-derived matter in the ocean fluxes to the ocean interior and the sea floor as marine snow. As microhabitats, marine snow aggregates contain enriched microbial communities and chemical gradients within which processes of photosynthesis, decomposition, and nutrient regeneration occur at highly elevated levels. Microbial communities associated with marine snow undergo complex successional changes on time scales of hours to days which significantly alter the chemical and biological properties of the particles. Marine snow can be produced either de novo by living plants and animals especially as mucus feeding webs of zooplankton, or by the biologically-enhanced physical aggregation of smaller particles. By the latter pathway, microaggregates, phytoplankton, fecal pellets, organic debris and clay-mineral particles collide by differential settlement or physical shear and adhere by the action of various, biologically-generated, organic compounds. Diatom flocculation is a poorly understood source of marine snow of potential global significance. Rates of snow production and breakdown are not known but are critical to predicting flux and to understanding biological community structure and transformations of matter and energy in the water column. The greatest challenge to the study of marine snow at present is the development of appropriate technology to measure abundances and characteristics of aggregates in situ.

    To study the feasibility of the classical image least significant bit (LSB) information hiding algorithm on quantum computer, a least significant qubit (LSQb) information hiding algorithm of quantum image is proposed. In this paper, we focus on a novel quantum representation for color digital images (NCQI). Firstly, by designing the three qubits comparator and unitary operators, the reasonability and feasibility of LSQb based on NCQI are presented. Then, the concrete LSQb information hiding algorithm is proposed, which can realize the aim of embedding the secret qubits into the least significant qubits of RGB channels of quantum cover image. Quantum circuit of the LSQb information hiding algorithm is also illustrated. Furthermore, the secrets extracting algorithm and circuit are illustrated through utilizing control-swap gates. The two merits of our algorithm are: (1) it is absolutely blind and (2) when extracting secret binary qubits, it does not need any quantum measurement operation or any other help from classical computer. Finally, simulation and comparative analysis show the performance of our algorithm.

    2017-01-01

    Full Text Available Microsatellite instability (MSI is a marker of the replication error phenotype. It is caused by impaired DNA mismatch repair processes (MMR, resulting in ineffectiveness of the mechanisms responsible for the DNA replication precision and postreplicative DNA repair. MSI underlies the pathogenesis of 10%–20% of colorectal cancer (CRC cases. The data about the potential value of MMR status as a predictive factor for 5-fluorouracil (FU-based chemotherapy remain unclear. According to National Comprehensive Cancer Network updated guidelines, MSI testing is recommended for all patients with stage II CRC because patients with MSI-H (high-frequency MSI tumour may have a good prognosis and obtain no benefit from 5-FU-based adjuvant chemotherapy. The significance of the MSI status as a predictive factor for patients with metastatic disease was not confirmed. The association between the MSI status and the efficacy of the therapy based on anti-programmed death-1 receptor inhibitors requires further studies.

    Convulsive status epilepticus is a common neurologic emergency in pediatrics. We aimed to study the etiology, clinical features, and prognostic factors among pediatric patients with convulsive status epilepticus. Seventy patients were included in this cohort study from pediatric emergency department of the specialized Children Hospital of Cairo University. The outcome was evaluated using the Glasgow Outcome Score. Acute symptomatic etiology was the most common cause of convulsive status epilepticus. Refractory convulsive status epilepticus was observed more significantly in cases caused by acute symptomatic etiologies. The outcome was mortality in 26 (37.1%) patients, severe disability in 15 (21.4%), moderate disability in 17 (24.3%), and good recovery in 12 (17.1%) patients. The significant predictor of mortality was lower modified Glasgow Coma Scale score on admission, whereas lower modified Glasgow Coma Scale score on admission and refractory convulsive status epilepticus were the significant predictors for disability and mortality.

    Full Text Available Little published information is available regarding epidemiological data on vitamin D status in the large geographical region of Central Europe (CE. We searched the journal literature with regard to 25(OHD concentrations among community-dwelling or healthy people living in CE. 25(OHD concentrations varied by age, season, study sample size, and methodological approach [i.e., 25(OHD assay used]. Concentrations of 25(OHD in CE appeared lower than 30 ng/mL, and the magnitude of hypovitaminosis D was similar to that reported in Western Europe. While most of the studies reviewed were cross-sectional studies, a longitudinal study was also included to obtain information on seasonal variability. The longitudinal study reported wintertime 25(OHD values close to 21–23 ng/mL for all studied age groups, with a significant increase of 25(OHD in August reaching 42 ng/mL for those aged 0–9 years, but only 21 ng/mL for the elderly aged 80–89 years. The decrease in 25(OHD with respect to age was attributed to decreased time spent in the sun and decreased vitamin D production efficiency. Based on the literature review on vitamin D status in the CE populations, it can be concluded that 25(OHvitamin D levels are on average below the 30 ng/mL level.

    A national epidemiological survey of children aged 5-14 years was conducted in all 5 governorates of Kuwait in 2001 to determine the oral hygiene status of Kuwait in schoolchildren. Clinical examinations were carried out by calibrated dentists according to World Health Organization criteria. The debris index simplified (DI-S) score was used to assess oral hygiene status. Of the 3294 children, 3.9% were judged to have good oral hygiene (DI-S score: 0.3-0.6), 67% fair (score 0.7-1.8) and 29.1% poor (score 1.9-3.0). The overall level of oral hygiene in the schoolchildren surveyed was fair (mean score 1.5). DI-S scores were significantly higher for boys than girls (mean score 1.6 versus 1.5) but DI-S did not vary much by age. There were variations in DI-S scores across different governorates. Oral hygiene measures need to be reinforced for the schoolchildren in Kuwait and should form part of the school curriculum.

    Full Text Available This study was an attempt to establish the extent of increased oxidative stress in hypercholesterolemic patients and to evaluate the effect of atorvastatin on the oxidative stress and antioxidant status. Blood samples of 15 subjects (age and sex matched from three groups: group I (healthy subjects, group II (hypercholesterolemic patients with atorvastatin treatment and group III (hypercholesterolemic patients without any hypolipidemic drug were taken and centrifuged to separate the plasma, which was used for the determination of vitamin E. The separated cells were washed thrice with 0.90 % w/v cold normal saline and used for the assay of the percentage hemolysis of the RBCs, and the determination of malondialdehyde, superoxide dismutase and hemoglobin. The levels of oxidative stress were higher in the hypercholesterolemic in comparison to the control and atorvastatin group. The levels of antioxidants were higher in the atorvastatin group than in the hypercholesterolemic one but were lower than the controls. From these findings, it was concluded that there is an increase in oxidative stress in hypercholesterolemia but it decreased significantly after 2 months of atorvastatin therapy and antioxidant status also improves in patients taking atorvastatin.

    It is important to control acoustic noise aboard the International Space Station (ISS) to provide a satisfactory environment for voice communications, crew productivity, alarm audibility, and restful sleep, and to minimize the risk for temporary and permanent hearing loss. Acoustic monitoring is an important part of the noise control process on ISS, providing critical data for trend analysis, noise exposure analysis, validation of acoustic analyses and predictions, and to provide strong evidence for ensuring crew health and safety, thus allowing Flight Certification. To this purpose, sound level meter (SLM) measurements and acoustic noise dosimetry are routinely performed. And since the primary noise sources on ISS include the environmental control and life support system (fans and airflow) and active thermal control system (pumps and water flow), acoustic monitoring will reveal changes in hardware noise emissions that may indicate system degradation or performance issues. This paper provides the current acoustic levels in the ISS modules and sleep stations and is an update to the status presented in 2011. Since this last status report, many payloads (science experiment hardware) have been added and a significant number of quiet ventilation fans have replaced noisier fans in the Russian Segment. Also, noise mitigation efforts are planned to reduce the noise levels of the T2 treadmill and levels in Node 3, in general. As a result, the acoustic levels on the ISS continue to improve.

  20. Drug-induced status epilepticus.

    Cock, Hannah R

    2015-08-01

    Drug-induced status epilepticus (SE) is a relatively uncommon phenomenon, probably accounting for less than 5% of all SE cases, although limitations in case ascertainment and establishing causation substantially weaken epidemiological estimates. Some antiepileptic drugs, particularly those with sodium channel or GABA(γ-aminobutyric acid)-ergic properties, frequently exacerbate seizures and may lead to SE if used inadvertently in generalized epilepsies or less frequently in other epilepsies. Tiagabine seems to have a particular propensity for triggering nonconvulsive SE sometimes in patients with no prior history of seizures. In therapeutic practice, SE is most commonly seen in association with antibiotics (cephalosporins, quinolones, and some others) and immunotherapies/chemotherapies, the latter often in the context of a reversible encephalopathy syndrome. Status epilepticus following accidental or intentional overdoses, particularly of antidepressants or other psychotropic medications, has also featured prominently in the literature: whilst there are sometimes fatal consequences, this is more commonly because of cardiorespiratory or metabolic complications than as a result of seizure activity. A high index of suspicion is required in identifying those at risk and in recognizing potential clues from the presentation, but even with a careful analysis of patient and drug factors, establishing causation can be difficult. In addition to eliminating the potential trigger, management should be as for SE in any other circumstances, with the exception that phenobarbitone is recommended as a second-line treatment for suspected toxicity-related SE where the risk of cardiovascular complications is higher anyways and may be exacerbated by phenytoin. There are also specific recommendations/antidotes in some situations. The outcome of drug-induced status epilepticus is mostly good when promptly identified and treated, though less so in the context of overdoses. This article is

    Herein, we evaluated the treatment strategy employing a therapeutic heterologous vaccine composed of antigens of Leishmania braziliensis associated with MPL adjuvant (LBMPL vaccine) for visceral leishmaniasis (VL) in symptomatic dogs naturally infected by Leishmania infantum. Sixteen dogs received immunotherapy with MPL adjuvant (n = 6) or with a vaccine composed of antigens of L. braziliensis associated with MPL (LBMPL vaccine therapy, n = 10). Dogs were submitted to an immunotherapeutic scheme consisting of 3 series composed of 10 subcutaneous doses with 10-day interval between each series. The animals were evaluated before (T0) and 90 days after treatment (T90) for their biochemical/hematological, immunological, clinical, and parasitological variables. Our major results showed that the vaccine therapy with LBMPL was able to restore and normalize main biochemical (urea, AST, ALP, and bilirubin) and hematological (erythrocytes, hemoglobin, hematocrit, and platelets) parameters. In addition, in an ex vivo analysis using flow cytometry, dogs treated with LBMPL vaccine showed increased CD3+ T lymphocytes and their subpopulations (TCD4+ and TCD8+), reduction of CD21+ B lymphocytes, increased NK cells (CD5−CD16+) and CD14+ monocytes. Under in vitro conditions, the animals developed a strong antigen-specific lymphoproliferation mainly by TCD4+ and TCD8+ cells; increasing in both TCD4+IFN-γ+ and TCD8+IFN-γ+ as well as reduction of TCD4+IL-4+ and TCD8+IL-4+ lymphocytes with an increased production of TNF-α and reduced levels of IL-10. Concerning the clinical signs of canine visceral leishmaniasis, the animals showed an important reduction in the number and intensity of the disease signs; increase body weight as well as reduction of splenomegaly. In addition, the LBMPL immunotherapy also promoted a reduction in parasite burden assessed by real-time PCR. In the bone marrow, we observed seven times less parasites in LBMPL animals compared with MPL group. The skin tissue showed a reduction in parasite burden in LBMPL dogs 127.5 times higher than MPL. As expected, with skin parasite reduction promoted by immunotherapy, we observed a blocking transmission to sand flies in LBMPL dogs with only three positive dogs after xenodiagnosis. The results obtained in this study highlighted the strong potential for the use of this heterologous vaccine therapy as an important strategy for VL treatment. PMID:28321217

    Helicobacter spp. are gram-negative, helically shaped bacteria that cause gastric and enterohepatic infections in mammalian species. Although Helicobacter infection frequently is implicated to interfere with reproductive success, few experimental data support these claims. We therefore retrospectively investigated the effect of Helicobacter infection on murine pregnancy outcome after the identification of endemic Helicobacter infection in an animal research facility. Multiplex conventional PCR analysis was used to characterize Helicobacter infection status in one inbred and 2 transgenic strains of mice in 2 self-contained rooms assigned to the same investigator. Outcomes of timed-mating experiments were compared among Helicobacter spp.-infected and uninfected mice of the same strain; Helicobacter infection was eradicated from the colony through fostering with uninfected dams. Although Helicobacter infection affected fecundity in only one strain of transgenic mouse, the total number of embryos per gravid uterus was significantly reduced in C57BL/6J mice that were infected with a single Helicobacter species, H. typhlonius. Helicobacter infection was also associated with a significant increase in the number of resorbing embryos per uterus and significant decreases in pregnancy-associated weight gain relative to uninfected mice in C57BL6/J mice and one transgenic strain. Helicobacter spp.-infected mice of all tested strains exhibited higher frequency of intrauterine hemorrhaging relative to uninfected mice. These results indicate that naturally-acquired Helicobacter infection not only reduces the productivity of a research animal breeding colony, but also negatively impacts embryo health. Despite these deleterious effects, these data suggest that colonies can be rederived to be Helicobacter-free by Cesarean section and fostering with uninfected dams. This paper provides the first evidence that H. typhlonius infection is sufficient to interfere with reproductive success

    Os odontoideum can lead to instability of the atlantoaxial joint and places the spinal cord at significant risk for acute catastrophic events after minor trauma or chronic neurological change. We present two cases of os odontoideum in pediatric patients that were not appreciated at earlier remote imaging but were, in retrospect, detectable. One patient presented with an acute spinal cord injury. Incorporating assessment of dens integrity into the evaluation algorithm for all pediatric cervical spine studies should lead to early detection of os odontoideum lesions and allow referral to appropriate clinical spinal services for evaluation, surveillance and possible surgery to prevent future complications.

Using examples from isobaric mass labelled proteomic experiments we show how to analyze data from multiple experiments simultaneously, and discuss the effects of missing data on the inference. We also present easy to use open source software for normalization of mass spectrometry data and inference based on moderated test statistics.

    Full Text Available Abstract The identification of phenotypically distinct HIV-1 variants with different prevalence during the progression of the disease has been one of the earliest discoveries in HIV-1 biology, but its relevance to AIDS pathogenesis remains only partially understood. The physiological basis for the phenotypic variability of HIV-1 was elucidated with the discovery of distinct coreceptors employed by the virus to infect susceptible cells. The role of the viral phenotype in the variable clinical course and treatment outcome of HIV-1 infection has been extensively investigated over the past two decades. In this review, we summarize the major findings on the clinical significance of the HIV-1 coreceptor usage.

  11. Is equal moral consideration really compatible with unequal moral status?

    Science.gov (United States)

    Rossi, John

    2010-09-01

    The issue of moral considerability, or how much moral importance a being's interests deserve, is one of the most important in animal ethics. Some leading theorists--most notably David DeGrazia--have argued that a principle of "equal moral consideration" is compatible with "unequal moral status." Such a position would reconcile the egalitarian force of equal consideration with more stringent obligations to humans than animals. The article presents arguments that equal consideration is not compatible with unequal moral status, thereby forcing those who would justify significantly different moral protections for humans and animals to argue for unequal consideration.

    Nonconvulsive status epilepticus has become an important issue in modern neurology and epileptology. This is based on difficulty in definitively elucidating the condition and its various clinical phenomena and on our inadequate insight into the intrinsic pathophysiological processes. Despite nonconvulsive status epilepticus being a situation that requires immediate treatment, this disorder may not be appreciated as the cause of mental status impairment. Although the pathophysiology of nonconvulsive status epilepticus remains unknown, this disorder is thought to lead to neuronal damage, so its identification and treatment are important. Nonconvulsive status epilepticus should be considered in the differential diagnosis of patients with liver cirrhosis presenting an altered mental status. We report a case of a 52-year-old male with liver cirrhosis presenting an altered mental status. He was initially diagnosed with hepatic encephalopathy but ultimately diagnosed with nonconvulsive status epilepticus by electroencephalogram.

  16. Why do nominal characteristics acquire status value? A minimal explanation for status construction.

    Science.gov (United States)

    Mark, Noah P; Smith-Lovin, Lynn; Ridgeway, Cecilia L

    2009-11-01

    Why do beliefs that attach different amounts of status to different categories of people become consensually held by the members of a society? We show that two microlevel mechanisms, in combination, imply a system-level tendency toward consensual status beliefs about a nominal characteristic. (1) Status belief diffusion: a person who has no status belief about a characteristic can acquire a status belief about that characteristic from interacting with one or more people who have that status belief. (2) Status belief loss: a person who has a status belief about a characteristic can lose that belief from interacting with one or more people who have the opposite status belief. These mechanisms imply that opposite status beliefs will tend to be lost at equal rates and will tend to be acquired at rates proportional to their prevalence. Therefore, if a status belief ever becomes more prevalent than its opposite, it will increase in prevalence until every person holds it.

    2017-07-01

    Creative industries constantly strive for fame and popularity. Though highly desirable, popularity is not the only achievement artistic creations might ever acquire. Leaving a longstanding mark in the global production and influencing future works is an even more important achievement, usually acknowledged by experts and scholars. `Significant' or `influential' works are not always well known to the public or have sometimes been long forgotten by the vast majority. In this paper, we focus on the duality between what is successful and what is significant in the musical context. To this end, we consider a user-generated set of tags collected through an online music platform, whose evolving co-occurrence network mirrors the growing conceptual space underlying music production. We define a set of general metrics aiming at characterizing music albums throughout history, and their relationships with the overall musical production. We show how these metrics allow to classify albums according to their current popularity or their belonging to expert-made lists of important albums. In this way, we provide the scientific community and the public at large with quantitative tools to tell apart popular albums from culturally or aesthetically relevant artworks. The generality of the methodology presented here lends itself to be used in all those fields where innovation and creativity are in play.

    Objective: Socioeconomic status (SES) is being recognized as an important factor in both social and medical problems. The aim of present study is to examine the relationship between SES and ischemic stroke and investigate whether SES is a predictor of clinical outcomes among patients with different neighborhood status from Shanghai, China. Methods: A total of 471 first-ever ischemic stroke patients aged 18-80 years were enrolled in this retrospective study. The personal SES of each patient was evaluated using a summed score derived from his or her educational level, household income, occupation, and medical reimbursement rate. Clinical adverse events and all-cause mortality were analyzed to determine whether SES was a prognostic factor, its prognostic impact was then assessed based on different neighborhood status using multivariable Cox proportional hazard models after adjusting for other covariates. Results: The individual SES showed a significant positive correlation with neighborhood status (r = 0.370; P < 0.001). The incidence of clinical adverse events and mortality were significantly higher in low SES patients compared with middle and high SES patients (P = 0.001 and P = 0.037, respectively). After adjusting other risk factors and neighborhood status, Kaplan-Meier analysis showed clinical adverse events and deaths were still higher in the low SES patients (all P < 0.05). Multivariate Cox regression analysis demonstrated that both personal SES and neighborhood status are independent prognostic factors for ischemic stroke (all P < 0.05). Besides, among patients with low and middle neighborhood status, lower individual SES was significantly associated with clinical adverse events and mortality (all P < 0.05). Conclusion: Both individual SES and neighborhood status are significantly associated with the prognosis after ischemic stroke. A lower personal SES as well as poorer neighborhood status may significantly increase risk for adverse clinical outcomes among

    Background: Pityriasis rosea (PR) is usually an asymptomatic and self-limiting papulosquamous skin disease with acute onset. The etiology has not been clarified yet. Recently, increased oxidative stress was found to play a role in etiopathogenesis of multiple cutaneous diseases with T cell-mediated immune response. However, there are no studies demonstrating the oxidative stress status in PR. Aim: The aim of the study is to determine the status of oxidative stress (OS) and paraoxonase (PON) 1/arylesterase enzyme activities in PR. Materials and Methods: Study included 51 patients with active PR lesions, and 45 healthy volunteers. Serum levels of total oxidant status (TOS), total antioxidant status (TAS), and PON1/arylesterase (ARES) activity were determined and oxidative stress index (OSI) was calculated in all patients and controls. Results: TAS levels and ARES activities in the patient group were significantly lower than the control group. On the other hand, TOS and OSI levels were significantly higher in patients compared with controls. There was no significant correlation between the duration of disease and TAS, TOS, OSI levels, and ARES activities. Conclusion: A systemic oxidative stress exists in PR, which suggests that OS may be involved in the etiopathogenesis of disease. PMID:26955119

  13. Significance of salmonella in pork production chain

    Directory of Open Access Journals (Sweden)

    Karabasil Neđeljko

    2008-01-01

    Full Text Available Animals, feed, meat and meat products are often transported across long distances, being an important part of international trade, which enables a dissemination of salmonella, including even of some resistant strains. Pigs are animals which are difficult to manipulate because of their temperament, build, sharp teeth, irritability, good sense of smell, bad sight and their sensitivity to stress. Animals coming from different farms should be separated in stock yards to prevent both contamination with pathogens such as salmonella and their irritation and aggressiveness caused by contacts with other pigs. These animals are usually a significant reservoir of salmonella which are 'inside' the gastrointestinal tract and gut associated lymph tissue. In contrast to our country, in the EU, even countries which have always had low salmonella prevalence, e.g. Finland, have a control program. The program has to be based on a guarantee that all relevant factors will participate in the prevention of salmonella contamination.

    In literature, existing researches on building recognition mainly concentrate on scales, rotations, and viewpoints variance. In urban environment, large temporal variations of weather and lighting conditions should also be considered as major challenges for robust recognition. For instances......, there are differences between images captured during daytime and nighttime, especially significant changes in building appearances between seasons because of the differences in light setting. To date, these large temporal variation issues have not been fully investigated. In this paper, we therefore focus...... on constructing a system that deals with the temporal difference factors in recognizing urban buildings. In order to build such a system, two main criteria are raised, namely the efficiency of the recognition algorithm and the speed for interactive search purpose.

    Terrorism has been the subject of many presidential and prime ministerial statements over the years. Sixteen weeks before the attacks on the World Trade Centre and the Pentagon, the American Secretary of State, referred to a report that indicated an 8 per cent increase in international terrorist attacks during year 2000 and stated that terrorism shows the dark side of globalization. Of the 423 recorded attacks, 200 were directed against the United States. This paper emphasizes three points to understand the significance of terrorism. First, it is necessary to understand the context within which terrorist acts are carried out, namely the modern world in its spiritual and its material dimensions. It is also necessary to understand the direction and trajectory of recent trends in terrorism and what can be done to stop it. 97 refs.

    One of the major threats to information security human error is often ignored or dismissed with statements such as {open_quotes}There is not much we can do about it.{close_quotes} This type of thinking runs counter to reality because studies have shown that, of all systems threats, human error has the highest probability of occurring and that, with professional assistance, human errors can be prevented or significantly reduced Security analysts often overlook human error as a major threat; however, other professionals such as human factors engineers are trained to deal with these probabilistic occurrences and mitigate them. In a recent study 55% of the respondents surveyed considered human error as the most important security threat. Documentation exists to show that human error was a major cause of the consequences suffered at Three Mile Island, Chernobyl, Bhopal, and the Exxon tanker, Valdez. Ironically, causes of human error can usually be quickly and easily eliminated.

  17. THRESHOLD OF SIGNIFICANCE IN STRESS MANAGEMENT

    Directory of Open Access Journals (Sweden)

    Elena RUSE

    2015-12-01

    Full Text Available Stress management is the individual's ability to handle any situation, external conditions, to match the demands of the external environment. The researchers revealed several stages in the stress response. A first phase was called ‘‘alert reaction'' or ‘‘immediate reaction to stress‘‘, phase in which there are physiological modifications and manifestations that occur under psychological aspect. Adaptation phase is the phase in which the reactions from the first phase diminishes or disappears. Exhaustion phase is related to the diversity of stress factors and time and may exceed the resources of the human body to adapt. Influencing factors may be: limited, cognitive, perceptual, and a priori. But there is a threshold of significance in stress management. Once the reaction to external stimuli occurs, awareness is needed. The capability effect occurs, any side effect goes away and comes out the ''I AM'' effect.

  18. Boiling significantly promotes photodegradation of perfluorooctane sulfonate.

    2015-11-01

    The application of photochemical processes for perfluorooctane sulfonate (PFOS) degradation has been limited by a low treatment efficiency. This study reports a significant acceleration of PFOS photodegradation under boiling condition compared with the non-boiling control. The PFOS decomposition rate increased with the increasing boiling intensity, but declined at a higher hydronium level or under oxygenation. These results suggest that the boiling state of solution resulted in higher effective concentrations of reactants at the gas-liquid interface and enhanced the interfacial mass transfer, thereby accelerating the PFOS decomposition. This study broadens our knowledge of PFOS photodegradation process and may have implications for development of efficient photodegradation technologies. Copyright © 2015 Elsevier Ltd.

  20. On Imaginative Criminology and Its Significance

    Directory of Open Access Journals (Sweden)

    Jon Frauley

    2015-08-01

    Full Text Available In growing numbers criminologists are discovering the value of imaginative and creative approaches for enquiry. There is now a critical mass of criminological work that engages substantively and theoretically with cultural artefacts such as film, fiction, music, dance, art, photography and cultural institutions. In doing so these works highlight criminology’s persistent epistemological and methodological weaknesses. The broad and fragmented “imaginative criminology” movement offers a challenge to an orthodox criminology that is guided by the coercive and constraining bureaucratic categories of criminal justice administration and the criminal law. Imaginative criminology displaces these as the governing categories of criminological thought and practice. Drawing on the work of Pierre Bourdieu, Louis Althusser, and C. Wright Mills this paper considers the movement’s epistemological significance and the challenge posed to criminological orthodoxy.

    Patients with type 2 diabetes mellitus are at the higher risk of development of on arteriosclerosis based cardiovascular diseases. Epidemiological studies have shown that diabetic dislipidemia with hypertriglyceridemia, presence of small dense LDL subfraction, low concentration of HDL-cholesterol and increased postprandial lipemia can represent a serious threat. Several studies have found significant decrease of cardiovascular morbidity and mortality after a treatment of diabetic dislipidemia, namely by statins and fibrates. Contemporary therapeutic algorhithms of European and American professional societies for the hyperlipidemia treatment classify diabetes mellitus as an equivalent of already developed complication of atherosclerosis. Our article presents pathophysiology of the diabetic dislipidemia, recommended target values of pasma lipids in diabetic patients and an overview of present possibilities of pharmacotherapy of the diabetic dislipidemia.

    As a great romantic novelist in America in 19th century, Hawthorne was outstanding in handling the application of symbolism. The Scarlet Letter is Hawthorne's most important symbolic novel, which stands as the best work of Hawthorne and one of the indubitable masterpieces of American literature. This thesis aims at the exploration of the usage of the symbolism in the novel. It mainly discusses the deep symbolic significance of the scarlet letter "A" and the little pearl. The scarlet letter is the central symbol of the novel. Its symbolic meaning changes from 'adultery' to 'able', even 'angelic' in the novel. It also examines the symbolic meanings of little Pearl and some typical natural surroundings such as the jail, the forest, the rosebush and so on.

    Dinoflagellates are microalgae that are associated with the production of many marine toxins. These toxins poison fish, other wildlife and humans. Dinoflagellate-associated human poisonings include paralytic shellfish poisoning, diarrhetic shellfish poisoning, neurotoxic shellfish poisoning, and ciguatera fish poisoning. Dinoflagellate toxins and bioactives are of increasing interest because of their commercial impact, influence on safety of seafood, and potential medical and other applications. This review discusses biotechnological methods of identifying toxic dinoflagellates and detecting their toxins. Potential applications of the toxins are discussed. A lack of sufficient quantities of toxins for investigational purposes remains a significant limitation. Producing quantities of dinoflagellate bioactives requires an ability to mass culture them. Considerations relating to bioreactor culture of generally fragile and slow-growing dinoflagellates are discussed. Production and processing of dinoflagellates to extract bioactives, require attention to biosafety considerations as outlined in this review.

Methods: We compared the EEG recordings of a group of 13 fibromyalgia patients with a normalized database built into the software of the equipment used (Neuronic, and also with a control group of 13 individuals; both groups were selected under the same criteria of inclusion-exclusion. Patients and controls underwent quantitative EEG (eyes closed, according to international 10-20 EEG system and were specifically evaluated throughout various neuropsychiatric and psychological questionnaires. Results: We obtained the absolute powers of QEEG (quantitative for the different electrode sites and frequency bands, we determined the corresponding values of the deviation from normal (Z-scores, and estimated various indicators and ratios, as well as correlations with the results of psychological tests. Interestingly, the ratios of theta and beta frequencies in relation with alpha appear as one of the most relevant indicators of the severity of the pathology; significant differences were also found in the peak frequency (maximum power per Hz of the alpha band, and in the frequency peak of the total spectrum. Conclusions: The consistency of the abnormal EEG patterns of fibromyalgia patients revealed the presence of systemic dysfunction at the central nervous system level, beyond possible peripheral anomalies and specific tissue pathologies. Among the indicators and benchmarks achieved, the most important changes concern the frequencies theta, alpha and beta, and still more significant were the values of their ratios in the comparison between patients and controls. The relative values of peak frequencies are also of

    Vitronectin (Vn), a multifunctional adhesive protein, is found in association with tumor progression, angiogenesis and metastasis in a variety of (human) tumors. But no studies concerning its correlation to osteosarcoma prognosis were found. Hence, we aimed to investigate the prognostic value of Vitronectin (Vn) in osteosarcoma. Here, we studied the expression of VN in the tumor tissues from 67 patients with osteosarcoma and 20 patients with osteochondroma using immunohistochemistry and estimated the effects of VN expression in osteosarcoma on progression-free survival (PFS) and overall survival (OS) using the Kaplan-Meier curve and COX proportional hazards regression model. Increased expression of VN in osteosarcoma tissue compared to no VN expression in osteochondroma tissue was shown in immunohistochemical assay. No associations were observed between VN expression and osteosarcoma patients' gender (P = 0.675), age (P = 0.813), tumor size (P = 0.436), histologic subtype (P = 0.0.543) or tumor location (P = 0.456). Univariate survival analysis demonstrated significant correlations of high VN expression with shorter PFS (P = 0.002) and OS (P = 0.001); multivariate survival analysis revealed high VN expression as a significant independent prognostic indicator for shorter PFS (HR 2.788, P = 0.003) and OS (HR2.817, P = 0.003). In conclusion, the high expression of VN in tumor cells independently indicated poor clinical prognosis in patients with osteosarcoma, other than large tumor size and non-neoadjuvant chemoradiotherapy, suggesting that VN may serve as a potential therapeutic target in osteosarcoma.

    Full Text Available The identification of cell surface markers, defined as clusters of differentiation antigens (CD’s could be used to classify and sub-classify leukemia. Although the same antigens are expressed on normal cells, the phenotype on malignant cells are aberrantly and frequently asynchronously expressed and may be present in combinations not observed in normal blood or bone marrow. Aberrant expression of surface antigens corresponds with poor therapeutic response and short survival. Additional surface marker analysis complementary to morphologic evaluation and cytochemical staining has greatly improved our ability to characterize hematologic malignancies. A review and illustration on the diagnostic significance of immunophenotyping in leukemia will be presented. Data from 225 patients having complete assessments including morphology, cytochemistry and immunophenotyping in the period of 1994-2001 were collected and analyzed. Based on morphologic evaluation and cytochemistry, the diagnosis of acute myeloid leukemia and acute lymphoblastic leukemia were established in 51.1% and 48.9% of cases, respectively. Based on immunophenotyping AML was found in 49.0% of the cases. ALL could be classified into 4.9% pre-B-ALL, 18.7% B-ALL, and 14.7% T-ALL. Cases expressing cross-lineage antigens were found in 12.7%. The prognostic significance of these aberrant expression of antigens for those cases has yet to be established but some of the cases responded poorly to therapy. Immunophenotyping provides the tool to: 1 distinguish normal from clonal populations of leukemic cells; 2 define lineage and reveal the stage of maturation; 3 identify inappropriate expression of lineage associated antigens; 4 provides more informations to establish diagnosis and prognosis compared to standard methods.

    Profile analysis was performed on 180 Thai female subjects with ages ranging from 16 to 21 years. Seventy were of Chinese origin. The determination of the profile analysis mean values was based on the methods of Schwarz, Subtelny, Ricketts, Burstone, and Schwartz. The results were compared to Caucasian standards and to the findings of our previous study on a Javanese population. For the profile forms, our investigated groups showed mainly prognathic faces (75% to 84%). A "shift backward" profile flow dominated. We found a "prognathic face" combined with a "shift backward" in 50% to 60% of the Asian subjects analyzed. Our soft-tissue profile results (approximately 165 +/- 6 degrees) showed less convexity than that of the Caucasians and there was no significant difference in overall profile between the 2 Thai groups (approximately 134 +/- 5 degrees); this is in the range given by Subtelny (141 degrees to 131 degrees) except for that of the Javanese subjects. For the lip analysis, we listed a posterior position or a lip position upon the esthetic line between 60% to 70% of both Thai groups with respect to the upper lip and only 28% to 33% for the lower lip. The Javanese group, however, showed 90% anterior position of the upper lip and 93% of the lower lip to this line. It is significant that proper blending of the integumentary profile produces an esthetically pleasing face and this varies in different ethnic groups. A good combination could even make a "prognathic face shift backward" very acceptable as illustrated by a profile analysis of Miss Thailand, 1984.(ABSTRACT TRUNCATED AT 250 WORDS)

    Background and Aims Questions over the clinical significance of cannabis withdrawal have hindered its inclusion as a discrete cannabis induced psychiatric condition in the Diagnostic and Statistical Manual of Mental Disorders (DSM IV). This study aims to quantify functional impairment to normal daily activities from cannabis withdrawal, and looks at the factors predicting functional impairment. In addition the study tests the influence of functional impairment from cannabis withdrawal on cannabis use during and after an abstinence attempt. Methods and Results A volunteer sample of 49 non-treatment seeking cannabis users who met DSM-IV criteria for dependence provided daily withdrawal-related functional impairment scores during a one-week baseline phase and two weeks of monitored abstinence from cannabis with a one month follow up. Functional impairment from withdrawal symptoms was strongly associated with symptom severity (p = 0.0001). Participants with more severe cannabis dependence before the abstinence attempt reported greater functional impairment from cannabis withdrawal (p = 0.03). Relapse to cannabis use during the abstinence period was associated with greater functional impairment from a subset of withdrawal symptoms in high dependence users. Higher levels of functional impairment during the abstinence attempt predicted higher levels of cannabis use at one month follow up (p = 0.001). Conclusions Cannabis withdrawal is clinically significant because it is associated with functional impairment to normal daily activities, as well as relapse to cannabis use. Sample size in the relapse group was small and the use of a non-treatment seeking population requires findings to be replicated in clinical samples. Tailoring treatments to target withdrawal symptoms contributing to functional impairment during a quit attempt may improve treatment outcomes. PMID:23049760

    1985-01-01

    The relationship between the vitamin B6 status of 180 pregnant women and the incidence and degree of morning sickness experienced during the first trimester was investigated. There were no significant differences in plasma pyridoxal 5'-phosphate (PLP), erythrocyte aspartate aminotransferase (AspAT) activity, and stimulation of erythrocyte AspAT activity by exogenous PLP between subjects who experienced morning sickness and those who did not. No relationship was found between these indicators of vitamin B6 status and the degree of morning sickness experienced by this group during early pregnancy. There were no differences in the number of women who experienced morning sickness or in the number with different degrees of sickness when plasma levels of PLP, erythrocyte AspAT activity or stimulation by PLP were divided into upper and lower 50th percentile groups and compared. Therefore these data show no relationship between vitamin B6 status and the incidence or degree of morning sickness.

    One of the most troublesome dynamics evident in the airplane cockpit is related to patterns of authority relations between the captain and the first officer: Too often, captains fail to listen and first officers fail to speak. The authors propose that many instances of superordinate and subordinate behavior in the cockpit--the captain's tendency to reject input from other team members and the first officer's hesitancy to question the captain--represent cases of status generalization. First, the authors describe the theory of status generalization and show support for the operation of the theory by presenring examples of flightcrew behavior that the theory predicts. Second, an initial empirical test was conducted to instantiate the claim that captain-first officer differences can be seen as status differences. Finally, the significance and implications of this perspective are discussed.

    Full Text Available Background Objectives: Alterations in the lipid profile have long been associated with various cancers because lipids play a key role in maintenance of cell integrity. This study was to estimate the plasma lipid levels in patients with oral cancer and to correlate the values with the histopathological grades. Materials and Methods: The study group included 50 patients with oral cancer aged between 20 and 60 years who had visited the Department of Oral Medicine and Radiology during the period of September 2005 to July 2007. After the histotopathological confirmation, their plasma lipid levels were estimated using auto analyzer and the data was statistically analyzed. Results: The study revealed a significant decrease in the total plasma lipid levels in patients with oral cancer in comparison with the standard values. Comparing the plasma lipid levels with the histopathological grades, we observed a significant variation in the levels of total cholesterol, very low density lipoprotein, low-density lipoprotein, high-density lipoprotein and triglycerides Conclusion: The variation in the levels of plasma cholesterol and other lipid constituents in patients with cancer might be due to their increased utilization by neoplastic cells for new membrane biosynthesis. This study was an attempt to estimate the plasma lipids in oral cancer patients and its significance on histopathological grades. We observed a relationship between lower plasma lipids and oral cancer. The result of our study strongly warrants an in-depth research with larger samples and a longer follow-up to consider the low plasma lipid status in oral cancer patients as a useful indicator to assess the course and prognosis of the disease.

    The 'Retinal Readout System' is being developed to study the language the eye uses to send information about the visual world to the brain. Its architecture is based on that of silicon microstrip detectors. An array of 512 microscopic electrodes picks up the signals generated by the output neurons of live retinal tissue in response to a dynamic image focused on the input neurons. These signals are amplified, filtered and multiplexed by a set of eight custom-designed VLSI readout chips, and digitized and recorded by a data acquisition system. This report describes the goals, design, and status of the system. (author)

    Objective: To investigate the expression of ERK and p-ERK protein in human breast cancer and their corresponding tissue, to assess the significance of ERK signal pathway in tumorigenesis and progression of breast carcinoma. Methods: 40 breast cancer cases were used in S-P immunohistochemistry technique and Western Blot study. Results: The expression of ERK1, ERK2, and p- ERK protein levels increased remarkably in breast cancer tissues in comparison to normal tissues (P<0.01). The expression was upregulated by 1.32-, 1.53-and 4.27-fold, respectively. The overexpressions of ERK1, ERK2, and p- ERK proteins were obviously correlated with clinical stage of breast cancer. Protein levels of ERK and p-ERK were higher in stage III patients than in stage I and stage II patients (P<0.05). These proteins were strongly related with axillary lymph node metastasis of breast cancer, but not correlated with histopathological type and status of ER and PR of breast cancer. Expression of ERK1, and ERK2, protein showed a positive linear correlation. Conclusion: ERK signal transduction pathway is a key factor during human breast tumorigenesis and breast cancer progression.

    Many children experiencing acute asthmatic episodes have chest radiographs, which may show lung hyperinflation, hypoinflation, or normal inflation. Lung hypoinflation may be a sign of respiratory fatigue and poor prognosis. To compare the clinical course in children with asthma according to the degree of lung inflation on chest radiographs. We conducted a retrospective study during a 24-month period (from July 1999 to July 2001) of children aged 0-17 years, who presented to a pediatric emergency department or outpatient clinic with an asthma exacerbation. Chest radiographs obtained at presentation were reviewed independently by three pediatric radiologists who were blinded to the admission status of the patient. The correlation between hypoinflation and hospital admission was assessed in three age groups: 0-2 years, 3-5 years, and 6-17 years. Hypoinflation on chest radiographs was significantly correlated with hospital admission for children aged 6-17 years (odds ratio 16.00, 95% confidence interval 1.89-135.43). The inter-reader agreement for interpretation of these radiographs was strong, with a kappa score of 0.76. Hypoinflation was not correlated with admission in younger children. Lung hypoinflation is associated with a greater likelihood of hospital admission in children aged 6 years or older. Therefore, hypoinflation was a poor prognostic sign and may warrant more aggressive therapy. (orig.)

  15. Immunological Effects of Probiotics and their Significance to Human Health

    Gill, Harsharn S.; Grover, Sunita; Batish, Virender K.; Gill, Preet

    Probiotics are defined as live microorganisms which when administered in adequate amounts confer a health benefit upon the host (FAO/WHO, 2001). Lactic acid bacteria, particularly Lactobacillus and Bifidobacterium species are commonly used as probiotics. Other less commonly used probiotics include the yeast Sacchromyces cerevisiae and some non-pathogenic Escherichia coli and Bacillus species. Studies over the past 20 years have demonstrated that probiotic intake is able to confer a range of health benefits including modulation of the immune system, protection against gastrointestinal and respiratory tract infections, lowering of blood cholesterol levels, attenuation of overt immuno-inflammatory disorders (such as inflammatory bowel disease, allergies) and anti-cancer effects. However, the strongest clinical evidence for probiotics relates to their effectiveness in improving gut health and modulating (via stimulation or regulation) the host immune system. This chapter provides an overview of the current status of our knowledge regarding the immunostimulatory and immunoregulatory effects of probiotics on the immune system and their significance to human health.

    Does task significance increase job performance? Correlational designs and confounded manipulations have prevented researchers from assessing the causal impact of task significance on job performance. To address this gap, 3 field experiments examined the performance effects, relational mechanisms, and boundary conditions of task significance. In Experiment 1, fundraising callers who received a task significance intervention increased their levels of job performance relative to callers in 2 other conditions and to their own prior performance. In Experiment 2, task significance increased the job dedication and helping behavior of lifeguards, and these effects were mediated by increases in perceptions of social impact and social worth. In Experiment 3, conscientiousness and prosocial values moderated the effects of task significance on the performance of new fundraising callers. The results provide fresh insights into the effects, relational mechanisms, and boundary conditions of task significance, offering noteworthy implications for theory, research, and practice on job design, social information processing, and work motivation and performance.

    We aimed to assess the effect of chemoradiotherapy on the nutritional status of patients with nasopharyngeal cancer (NPC) and to detect the risk factors for poor nutrition status in NPC patients after radiotherapy. A total of 104 NPC patients participated in this clinical observational study. Psychological distress and nutritional indicators were measured prior to chemoradiotherapy. During the course of radiation therapy, side effect symptoms were assessed weekly. At the end of radiotherapy, nutritional indicators were measured again. Logistic regression was used to identify the risk factors for poor nutritional status after radiotherapy. The values of the 9 nutritional indicators were significantly lower after radiotherapy (P nutritional status were old age (P = 0.042), female gender (P nutritional status before radiotherapy (P = 0.015). Radiotherapy affects the nutritional status of NPC patients. To prevent malnutrition during radiotherapy, nutritional assessment and intervention should be an integral part of treatment.

    Full Text Available OBJECTIVE: to explore the relationship between socioeconomic status and subjective social status and explain how subjective social status predicts health in immigrant women. METHODS: cross-sectional study based on data from 371 Latin American women (16-65 years old from a total of 7,056 registered immigrants accesse through community parthers between 2009-2010. Socioeconomic status was measured through education, income and occupation; subjective social status was measured using the MacArthur Scale, and perceived health, using a Likert scale. RESULTS: a weak correlation between socioeconomic and subjective social status was found. In the bivariate analysis, a significantly higher prevalence of negative perceived health in women with no education, low income, undocumented employment was observed. In the multivariate analysis, higher odds of prevalence of negative perceptions of health in the lower levels of the MacArthur scale were observed. No significant differences with the rest of the variables were found. CONCLUSIONS: the study suggests that subjective social status was a better predictor of health status than the socioeconomic status measurements. Therefore, the use of this measurement may be relevant to the study of health inequalities, particularly in socially disadvantaged groups such as immigrants.

    The current status for the ATF2 Nominal and Ultra-low {beta}* lattices are presented in this paper. New lattice designs have been obtained in order to minimise the impact of the last interpretation of multipole measurements that have been included into the model. However, the new ATF2 Ultra-low design is not able to recover the expected vertical beam size at the IP with the current magnet distribution. Therefore, different quadrupole sorting have been studied. A significant gain is evident for the ATF2 Ultra-low lattice when sorting the magnets according to the skew-sextupolar components. The ATF2 Nominal lattice is also expected to benefit from the new sorting. Tuning results of the new ATF2 Ultra-low lattice under realistic imperfections are also reported.

    2008-01-01

    In the Subsonics Rotary Wing (SRW) Project being funded for propulsion work at NASA Glenn Research Center, performance of the propulsion system is of high importance. In current rotorcraft drive systems many gearing components operate at high rotational speed (pitch line velocity > 24000 ft/ min). In our testing of high speed helical gear trains at NASA Glenn we have found that the work done on the air - oil mist within the gearbox can become a significant part of the power loss of the system. This loss mechanism is referred to as windage. The effort described in this presentation is to try to understand the variables that affect windage, develop a good experimental data base to validate, the analytical project being conducted at Penn State University by Dr. Rob Kunz under a NASA SRW NRA. The presentation provides an update to the status of these efforts.

    The system of ITER Cryodistribution (CD) and Cryolines (CLs) is an integral interface between the Cryoplant systems and the superconducting (SC) magnets as well as Cryopumps (CPs). The project has progressed from the conceptual stage to the industrial stage. The subsystems are at various stages of design as defined by the project, namely, preliminary design, final design and formal reviews. Significant progresses have been made in the prototypes studies and design validations, such as the CL and cold circulators. While one of the prototype CL is already tested, the other one is in manufacturing phase. Performance test of two cold circulators have been completed. Design requirements are unique due the complexity arising from load specifications, layout constraints, regulatory compliance, operating conditions as well as several hundred interfaces. The present status of the project in terms of technical achievements, implications of the changes and the technical management as well as the risk assessment and its mitigation including path forward towards realization is described.

    Refractory status epilepticus (RSE) is a life-threatening emergency, demonstrating, by definition, significant pharmacoresistance. We describe five cases of pediatric RSE treated with mild hypothermia. Retrospective chart review was performed of records of children who received hypothermia for RSE at two tertiary-care pediatric hospitals between 2009 and 2012. Five children with RSE received mild hypothermia (32-35°C). Hypothermia reduced seizure burden during and after treatment in all cases. Prior to initiation of hypothermia, four children (80%) received pentobarbital infusions to treat RSE, but relapsed after pentobarbital discontinuation. No child relapsed after treatment with hypothermia. One child died after redirection of care. Remaining four children were discharged. This is the largest pediatric case series reporting treatment of RSE with mild hypothermia. Hypothermia decreased seizure burden during and after pediatric RSE and may prevent RSE relapse.

The vacuum vessel,port, cryostat cylinder, lid, and bellows are being rigorously fabricated in the factory. The lower part of the KSTAR such as cryostat base and gravity support has been almost finished in its fabrication. There are also great progresses and significant results in manufacturing of the superconducting magnet, including four Toroidal Field (TF) coils, lower and upper PF7 coils which are the largest Poloidal Field (PF) coils. The TF00 coil, which has been made for test and back-up of the TF magnet system, was successfully tested in the cool-down and current charging. As the fabrications and procurements of major structures have been actively proceeded, assembly works were also launched from Aug. 2003. More detailed description on these status, results, and plans will be described in this paper.

    More and more data seem to indicate the presence of an increasing number of syndromes and genetic diseases characterized by impaired bone mass and quality. Meanwhile, the improvement of etiopathogenetic knowledge and the employment of more adequate treatments have generated a significant increase in survival related to these syndromes and diseases. It is thus important to identify and treat bone impairment in these patients in order to assure a better quality of life. This review provides an updated overview of bone pathophysiology and characteristics in patients with Down, Turner, Klinefelter, Marfan, Williams, Prader-Willi, Noonan, and 22q11 deletions syndrome. In addition, some options for the treatment of the bone status impairment in these patients will be briefly discussed.

    In its most common configuration, solid oxide fuel cell (SOFC) uses an oxygen ion conducting ceramic electrolyte membrane, perovskite cathode and nickel cermet anode electrode. Cells operate in the 600-1000 C temperature range and utilize metallic or ceramic current collectors for cell-to-cell interconnection. Recent development in engineered electrode architectures, component materials chemistry, cell and stack designs and fabrication processes have led to significant improvement in the electrical performance and performance stability as well as reduction in the operating temperature of such cells. Large kW-size power generation systems have been designed and field demonstrated. This paper reviews the status of SOFC power generation systems with emphasis on cell and stack component materials, electrode reactions, materials reactions and corrosion processes

    This paper presents the results of the latest survey on information security management and pracitces in organisations. The study is based on a holistic approach to information security that does not confine itself to technical measures and technology implementations, but encompasses other equally important aspects such as human, social, motiviational and trust. In order to achieve this purpose, a comprehensive intellectual framework of the concepts of information security using Soft Systems Methodology (SSM) was utilised. The survey questions were drived from this conceptual model to ensure their coherence, completeness and relevance to the topic being addressed. The paper concludes with a discussion of the survey results and draws significant insight into the existing status of informaiton assurance in organisations that could be useful for security practitioners, researchers and managers.

    The precise measurement of cosmic-ray antiparticles serves as important means for identifying the nature of dark matter. Recent years showed that identifying the nature of dark matter with cosmic-ray positrons and higher energy antiprotons is difficult, and has lead to a significantly increased interest in cosmic-ray antideuteron searches. Antideuterons may also be generated in dark matter annihilations or decays, offering a potential breakthrough in unexplored phase space for dark matter. Low-energy antideuterons are an important approach because the flux from dark matter interactions exceeds the background flux by more than two orders of magnitude in the low-energy range for a wide variety of models. This review is based on the "dbar14 - dedicated cosmic-ray antideuteron workshop", which brought together theorists and experimentalists in the field to discuss the current status, perspectives, and challenges for cosmic-ray antideuteron searches and discusses the motivation for antideuteron searches, the theor...

    Full Text Available The objective of this study was to evaluate and compare the periodontal status of orthodontic patients and non-orthodontic patients, aged 15–28 years, of both genders. The cross-sectional study included 100 orthodontic and 100 non-orthodontic patients evaluated using a Community Periodontal Index for Treatment Need (CPITN probe on the index teeth. A questionnaire was distributed to the participants to assess and evaluate the use of oral hygiene aids. The data were analyzed using SPSS version 17, and various comparisons were performed using the chi-square test. The study revealed that there was a statistically significant association in CPITN scores between the orthodontic and non-orthodontic patients (p < 0.01. The study showed that patients undergoing orthodontic treatment have increased plaque accumulation and probing depth resulting in periodontal tissue destruction. Proper oral hygiene practices and interdental aids should be employed to control plaque.

    Reliable, real-time heart and respiratory rates are key vital signs used in evaluating the physiological status in many clinical and non-clinical settings. Measuring these vital signs generally requires superficial attachment of physically or logistically obtrusive sensors to subjects that may result in skin irritation or adversely influence subject performance. Given the broad acceptance of ingestible electronics, we developed an approach that enables vital sign monitoring internally from the gastrointestinal tract. Here we report initial proof-of-concept large animal (porcine) experiments and a robust processing algorithm that demonstrates the feasibility of this approach. Implementing vital sign monitoring as a stand-alone technology or in conjunction with other ingestible devices has the capacity to significantly aid telemedicine, optimize performance monitoring of athletes, military service members, and first-responders, as well as provide a facile method for rapid clinical evaluation and triage.

    Adolescence represents a pivotal stage in the development of positive or negative body image. Many influences exist during the teen years including transitions (eg, puberty) that affect one's body shape, weight status, and appearance. Weight status exists along a spectrum between being obese (ie, where one's body weight is in the 95th percentile for age and gender) to being underweight. Salient influences on body image include the media, which can target adolescents, and peers who help shape beliefs about the perceived body ideal. Internalization of and pressures to conform to these socially prescribed body ideals help to explain associations between weight status and body image. The concepts of fat talk and weight-related bullying during adolescence greatly contribute to an overemphasis on body weight and appearance as well as the development of negative body perceptions and dissatisfaction surrounding specific body parts. This article provides an overview of the significance of adolescent development in shaping body image, the relationship between body image and adolescent weight status, and the consequences of having a negative body image during adolescence (ie, disordered eating, eating disorders, and dysfunctional exercise). Practical implications for promoting a healthy weight status and positive body image among adolescents will be discussed.

    Full Text Available BACKGROUND Tribals are one of the most vulnerable groups in India. Under-nutrition and various morbidities go hand in hand, particularly in children. Nutritional status is a sensitive indicator of community health and nutrition. The present study is an attempt to assess the nutritional status of pre-school children of Kozhikode district in Kerala. The objectives of this study were 1. To study the prevalence of malnutrition among the preschool tribal children 2. To study the associated risk factors. MATERIALS AND METHODS The study was a community-based, cross- sectional. Study was carried out in randomly selected 10 panchayaths in Kozhikode. Cluster sampling method was used. Anthropometric measurements were taken. Various indices of nutritional status were expressed in standard deviation units (z scores from the reference median. RESULTS More than half of the children say 57.6% (152/246 had deficits in at least one of the two anthropometric indicators. The prevalence of underweight and stunting was 47.3% and .38.6% respectively. The analysis showed significant associations between under-nutrition and educational status of mother, tribe to which the child belonged, large family size, high birth order and low preschool attendance. CONCLUSION The findings of the present study revealed the widespread prevalence of under-nutrition among pre-school tribal children and highlight a need for an integrated approach towards improving the child health as well as nutritional status in this area.

    This paper discusses the concept of social capital as a potential factor in understanding the controversial relationship between income inequality and individual health status, arguing a positive, important role for social capital. Most of the health research literature focuses on individual health status and reveals that social capital increases individual health. However, the difficulty in measuring social capital, together with what may be the nearly impossible task of attributing causality, should relegate the concept to a more theoretical role in health research. Nonetheless, social capital receives academic attention as a potentially important factor in health research. This paper finds that the mixed results of empirical research on income inequality and health status remain a problem in the context of defining a stable relationship between socioeconomic status and health status. Clearly, further research is needed to elaborate on the income inequality and health relationship. In addition, focused, rigorous examination of social capital in a health context is needed before health researchers can comfortably introduce it as a concept of influence or significance.

    We investigated serum total oxidative and anti-oxidative status in manic patients. Group1 was formed as ECT+antipsychotic, group2 was antipsychotic and healthy volunteers as group3. The anti-oxidative status was significantly lower in group1 than group3. No significant change was found between pre and post-treatment oxidative and anti-oxidative status, whereas significantly increased oxidative stress index has been found in group2. Total anti-oxidative status in manic states seems to be inadequate which remains to be maintained after the treatment. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  16. Assessing statistical significance in causal graphs

    Full Text Available Abstract Background Causal graphs are an increasingly popular tool for the analysis of biological datasets. In particular, signed causal graphs--directed graphs whose edges additionally have a sign denoting upregulation or downregulation--can be used to model regulatory networks within a cell. Such models allow prediction of downstream effects of regulation of biological entities; conversely, they also enable inference of causative agents behind observed expression changes. However, due to their complex nature, signed causal graph models present special challenges with respect to assessing statistical significance. In this paper we frame and solve two fundamental computational problems that arise in practice when computing appropriate null distributions for hypothesis testing. Results First, we show how to compute a p-value for agreement between observed and model-predicted classifications of gene transcripts as upregulated, downregulated, or neither. Specifically, how likely are the classifications to agree to the same extent under the null distribution of the observed classification being randomized? This problem, which we call "Ternary Dot Product Distribution" owing to its mathematical form, can be viewed as a generalization of Fisher's exact test to ternary variables. We present two computationally efficient algorithms for computing the Ternary Dot Product Distribution and investigate its combinatorial structure analytically and numerically to establish computational complexity bounds. Second, we develop an algorithm for efficiently performing random sampling of causal graphs. This enables p-value computation under a different, equally important null distribution obtained by randomizing the graph topology but keeping fixed its basic structure: connectedness and the positive and negative in- and out-degrees of each vertex. We provide an algorithm for sampling a graph from this distribution uniformly at random. We also highlight theoretical

    An estimated 1049 million persons harbour T. trichiura, including 114 million preschool-age children and 233 million school-age children. The prevalence of T. trichiura is high and may reach 95% in children in many parts of the world where protein energy malnutrition and anaemias are also prevalent and access to medical care and educational opportunities is often limited. The Trichuris dysentery syndrome (TDS) associated with heavy T. trichiura, which includes chronic dysentery, rectal prolapse, anaemia, poor growth, and clubbing of the fingers constitutes an important public health problem, as do lighter but still heavy infections, even if not strictly TDS, especially in children. The profound growth stunting in TDS can be reversed by repeated treatment for the infection and, initially, oral iron. However findings from Jamaica strongly suggest that the significant developmental and cognitive deficits seen are unlikely to disappear without increasing the positive psychological stimulation in the child's environment. The severe stunting in TDS now appears likely to be a reaction at least in part to a chronic inflammatory response and concomitant decreases in plasma insulin-like growth factor-1 (IGF-1), increases in tumor necrosis factor-alpha (TNF-alpha) in the lamina propria of the colonic mucosa and peripheral blood (which likely decrease appetite and intake of all nutrients) and a decrease in collagen synthesis. Improvements in cognitive performance have been found after treatment for relatively heavy infections (without chronic dysentery) in school-going children; it is unclear precisely how much T. trichiura interferes with children's ability to access educational opportunities, but treatment of infections whenever possible is obviously sensible. The blood loss that can occur in T. trichiura infection is likely to contribute to anaemia, particularly if the child also harbours hookworm, malaria and/or has a low intake of dietary iron. Community control is

    Full Text Available BACKGROUND: Erythropoietin (Epo administration has been reported to have tumor-promoting effects in anemic cancer patients. We investigated the prognostic impact of endogenous Epo in patients with pancreatic ductal adenocarcinoma (PDAC. METHODOLOGY: The clinico-pathological relevance of hemoglobin (Hb, n = 150, serum Epo (sEpo, n = 87 and tissue expression of Epo/Epo receptor (EpoR, n = 104 was analyzed in patients with PDAC. Epo/EpoR expression, signaling, growth, invasion and chemoresistance were studied in Epo-exposed PDAC cell lines. RESULTS: Compared to donors, median preoperative Hb levels were reduced by 15% in both chronic pancreatitis (CP, p<0.05 and PDAC (p<0.001, reaching anemic grade in one third of patients. While inversely correlating to Hb (r = -0.46, 95% of sEPO values lay within the normal range. The individual levels of compensation were adequate in CP (observed to predicted ratio, O/P = 0.99 but not in PDAC (O/P = 0.85. Strikingly, lower sEPO values yielding inadequate Epo responses were prominent in non-metastatic M0-patients, whereas these parameters were restored in metastatic M1-group (8 vs. 13 mU/mL; O/P = 0.82 vs. 0.96; p<0.01--although Hb levels and the prevalence of anemia were comparable. Higher sEpo values (upper quartile ≥ 16 mU/ml were not significantly different in M0 (20% and M1 (30% groups, but were an independent prognostic factor for shorter survival (HR 2.20, 10 vs. 17 months, p<0.05. The pattern of Epo expression in pancreas and liver suggested ectopic release of Epo by capillaries/vasa vasorum and hepatocytes, regulated by but not emanating from tumor cells. Epo could initiate PI3K/Akt signaling via EpoR in PDAC cells but failed to alter their functions, probably due to co-expression of the soluble EpoR isoform, known to antagonize Epo. CONCLUSION/SIGNIFICANCE: Higher sEPO levels counteract anemia but worsen outcome in PDAC patients. Further trials are required to clarify how overcoming a sEPO threshold

    Full Text Available Abstract Background The nutritional status of the aging individual results from a complex interaction between personal and environmental factors. A disease influences and is influenced by the nutritional status and the functional capacity of the individual. We asses the relationship between nutritional status and indicators of functional capacity among recently hospitalized elderly in a general hospital. Methods A cross-sectional study was done with 240 elderly (women, n = 127 and men, n = 113 hospitalized in a hospital that provides care for the public and private healthcare systems. The nutritional status was classified by the MNA (Mini Nutritional Assessment into: malnourished, risk of malnutrition and without malnutrition (adequate. The functional autonomy indicators were obtained by the self-reported Instrumental Activity of Daily Living (IADL and Activity of Daily Living (ADL questionnaire. The chi-square test was used to compare the proportions and the level of significance was 5%. Results Among the assessed elderly, 33.8% were classified as adequate regarding nutritional status; 37.1% were classified as being at risk of malnutrition and 29.1% were classified as malnourished. All the IADL and ADL variables assessed were significantly more deteriorated among the malnourished individuals. Among the ADL variables, eating partial (42.9% or complete (12.9% dependence was found in more than half of the malnourished elderly, in 13.4% of those at risk of malnutrition and in 2.5% of those without malnutrition. Conclusion There is an interrelationship between the nutritional status of the elderly and reduced functional capacity.

    Nutritional status is an important consideration in many pediatric clinical conditions. This paper aimed to examine and compare the nutritional status, represented by body cell mass (BCM), of children with cancer, Crohn's disease (CD), cystic fibrosis (CF) and anorexia nervosa (AN). Anthropometry was measured and BCM was calculated from whole body potassium-40 counting in 259 children being treated for clinical conditions (n = 66 cancer; n = 59 AN; n = 75 CF; n = 59 CD) and 108 healthy children. BCM was adjusted for height (BCMI) and expressed as a Z-score relative to laboratory reference data. The CD (-0.80 ± 1.61; p = 0.0001) and AN (-1.13 ± 0.99; p = 0.0001) groups had significantly lower BMI Z-score than the healthy control (0.13 ± 0.75), cancer (0.50 ± 1.40) and CF groups (-0.09 ± 0.95). The cancer (-1.16 ± 1.60; p = 0.0001), CD (-1.13 ± 1.36; p = 0.0001) and AN (-0.97 ± 1.18; p = 0.0001) groups had significantly reduced BCM compared to the healthy control (0.07 ± 0.93) and CF group (0.31 ± 1.08). According to BCMI Z-score, 42.4% of patients with cancer, 41.7% of the patients with CD, 27.1% of patients with AN, and 4.0% of patients with CF were considered malnourished. This study demonstrates that children undergoing treatment for clinical conditions may have alterations in BCM, independent of BMI. Children with cancer, CD and AN all had a high prevalence of malnutrition. Assessment of body composition, not just body size, is vital to understand nutritional status in children with clinical conditions.
