    While it is common to speak about "Roma culture" as a single entity, the questions posed by Roma culture are more complex. We are speaking about the general issues pertaining to various manifestations of this culture in the context of the Czech Republic. It must be stressed that under "Roma," we understand a family resemblance…

    The health status of the so-called "Roma" is usually much poorer than that of neighbouring non-Roma populations with a life expectancy gap of 5-15 years. This results from prolonged exposure to adverse determinants of health and to persistent exclusion from social and political arenas. Scientific and social research has only poorly addressed the health issues of Roma and evidences are scarce. Insufficient access to public services, including to health care and non optimal clinical practices are modifiable factors. If correctly addressed, this could contribute to reduce health disparities, including in Switzerland. PMID:26027205

    Background: The research and published literature on Roma health in Turkey is much more limited than in other European countries. Among these, there are hardly any published literature focusing on the health status, health indicators and health behaviors. Aims: The aim of this research is to describe the perceptions of health-related concepts and access and the use of health services and social determinants of the health of Roma people in Turkey. Study Design: Descriptive qualitative survey. Methods: The participants were chosen by random sampling. The semi-structured interview topic guide was developed from sources such as advice from the Romani community leaders, published evidence and personal experience from previous work with Roma communities. Non-directive open-ended questions allowed the exploration of their health status, how they conceptualize health and disease, their level of awareness on the impact of social determinants of health, on their health status and the access and use of health services. The data analysis was based on grounded theory. Analysis proceeded in four steps: 1. Reading and examining the transcripts separately using open coding, 2. Extracting the key words and codes from the transcripts and sorting them into categories, 3. Re-reading the transcripts by using selective coding, and 4. Examining the categories derived from the open coding systematically and determining the concepts summarizing the material. Results: The survey results are compatible with the existing literature on Roma health and reveal that 1) there is a tight link between the lack of social determinants of health and the poor health status of Roma people 2) socioeconomic factors and cultural norms of the ethnic minority are suspicious factors 3) comparative and systematic research is needed to illuminate the actual health gaps and causal factors for them. Conclusion: The research proves that the need for comparative and systematic research in Turkey to determine the

    According to the literature data, Roma health and living conditions in Central and Eastern Europe are poorer than of the rest of population. However, the more detailed information about Roma health is lacking. The aim of the study was to evaluate morbidity, health self-assessment, and prevalence of addictions among Roma children in Vilnius and Ventspils and to compare with health indicators of non-Roma children. PARTICIPANTS AND METHODS. A descriptive epidemiological study was carried out, anonymously questioning all volunteer Roma children - 59 in Vilnius (Lithuania) and 31 in Ventspils (Latvia) schools. Results were compared with identical study, carried out in five Vilnius schools (reference group, 640). RESULTS. The appliance rate of Roma children to doctor did not differ from reference group - half of all questioned children visited doctor 1-3 times during the last year. However, more Roma children (74.6% from Vilnius and 64.6% from Ventspils) considered their health as poor and very poor as compared to reference group (4.3%). The proportion of children indicating somatic symptoms often and very often did not differ statistically significantly among groups with exception of vomiting and nausea, which was most prevalent among Vilnius Roma and Ventspils Roma. The proportion of children indicating emotional symptoms often and very often differed significantly in all groups and was the biggest in Ventspils Roma group. The proportion of daily alcohol, drug users, and smokers was higher in Vilnius Roma and Ventspils Roma groups, although the differences among all three groups were not statistically significant. CONCLUSION. Although the morbidity of Vilnius Roma and Ventspils Roma groups did not differ from reference group, essential discrepancy was found in health self-assessment - more Roma children considered their health as poor and very poor.

    Roma people in B&H are a marginalised population group. Their health condition; is considerably worse than the condition of other population groups. The health problems of Roma people correlate with inadequate living and dwelling conditions. Roma children are facing the impossibility of being health care beneficiaries, because their parents are unemployed. The objective of this survey was to examine the family surrounding of children in age up to 8 years, including the social conditions under which they live and the presence of health risk behaviour. The research presents a descriptive cross-section study. We interviewed 1100 non-Roma parents and children and 383 Roma parents and children (in the communities of domicile Roma people) in B&H Federation. The results obtained indicate that only 17,8 % of Roma parents are secondary-school leavers, while remaining percentage covers those with incomplete primary school or without education at all, against 63,6% of non-Roma parents who have secondary education. The parents consider themselves good providers for their children (59,3% of Roma parents and 75% of non-Roma parents often play with their children). The Roma parents seek for medical attention for their children only in the cases when urgent health problems occur, such as fever/increased body temperature (one-half of the interviewed parents) or diarrhoea (31,9%). Physical punishment of children occurs more frequently in Roma families (23,7% - this is only the top of an iceberg) then in non-Roma families (11,4%). The parents usually beat children by using their hands or punish them by flogging. The domestic violence is accepted amongst Roma people and it has most sever impact on children, who suffer emotionally and physically. In the future, it will be necessary to create the kind of family environment that would enable improvement of health condition and decrease the behaviour that endangers the health of children.

    The Roma, also known as 'Gypsies', represent the largest and the most widespread ethnic minority of Europe. There is increasing evidence, based on linguistic, anthropological and genetic data, to suggest that they originated from the Indian subcontinent, with subsequent bottlenecks and undetermined gene flow from/to hosting populations during their diaspora. Further support comes from the presence of Indian uniparentally inherited lineages, such as mitochondrial DNA M and Y-chromosome H haplogroups, in a significant number of Roma individuals. However, the limited resolution of most genetic studies so far, together with the restriction of the samples used, have prevented the detection of other non-Indian founder lineages that might have been present in the proto-Roma population. We performed a high-resolution study of the uniparental genomes of 753 Roma and 984 non-Roma hosting European individuals. Roma groups show lower genetic diversity and high heterogeneity compared with non-Roma samples as a result of lower effective population size and extensive drift, consistent with a series of bottlenecks during their diaspora. We found a set of founder lineages, present in the Roma and virtually absent in the non-Roma, for the maternal (H7, J1b3, J1c1, M18, M35b, M5a1, U3, and X2d) and paternal (I-P259, J-M92, and J-M67) genomes. This lineage classification allows us to identify extensive gene flow from non-Roma to Roma groups, whereas the opposite pattern, although not negligible, is substantially lower (up to 6.3%). Finally, the exact haplotype matching analysis of both uniparental lineages consistently points to a Northwestern origin of the proto-Roma population within the Indian subcontinent. PMID:26374132

    The Roma people, living throughout Europe and West Asia, are a diverse population linked by the Romani language and culture. Previous linguistic and genetic studies have suggested that the Roma migrated into Europe from South Asia about 1,000–1,500 years ago. Genetic inferences about Roma history have mostly focused on the Y chromosome and mitochondrial DNA. To explore what additional information can be learned from genome-wide data, we analyzed data from six Roma groups that we genotyped at hundreds of thousands of single nucleotide polymorphisms (SNPs). We estimate that the Roma harbor about 80% West Eurasian ancestry–derived from a combination of European and South Asian sources–and that the date of admixture of South Asian and European ancestry was about 850 years before present. We provide evidence for Eastern Europe being a major source of European ancestry, and North-west India being a major source of the South Asian ancestry in the Roma. By computing allele sharing as a measure of linkage disequilibrium, we estimate that the migration of Roma out of the Indian subcontinent was accompanied by a severe founder event, which appears to have been followed by a major demographic expansion after the arrival in Europe.

    The identification of a growing number of novel Mendelian disorders and private mutations in the Roma (Gypsies) points to their unique genetic heritage. Linguistic evidence suggests that they are of diverse Indian origins. Their social structure within Europe resembles that of the jatis of India, where the endogamous group, often defined by profession, is the primary unit. Genetic studies have reported dramatic differences in the frequencies of mutations and neutral polymorphisms in different Romani populations. However, these studies have not resolved ambiguities regarding the origins and relatedness of Romani populations. In this study, we examine the genetic structure of 14 well-defined Romani populations. Y-chromosome and mtDNA markers of different mutability were analyzed in a total of 275 individuals. Asian Y-chromosome haplogroup VI-68, defined by a mutation at the M82 locus, was present in all 14 populations and accounted for 44.8% of Romani Y chromosomes. Asian mtDNA-haplogroup M was also identified in all Romani populations and accounted for 26.5% of female lineages in the sample. Limited diversity within these two haplogroups, measured by the variation at eight short-tandem-repeat loci for the Y chromosome, and sequencing of the HVS1 for the mtDNA are consistent with a small group of founders splitting from a single ethnic population in the Indian subcontinent. Principal-components analysis and analysis of molecular variance indicate that genetic structure in extant endogamous Romani populations has been shaped by genetic drift and differential admixture and correlates with the migrational history of the Roma in Europe. By contrast, social organization and professional group divisions appear to be the product of a more recent restitution of the caste system of India. PMID:11704928

    The 8–10 million European Roma/Gypsies are a founder population of common origins that has subsequently split into multiple socially divergent and geographically dispersed Gypsy groups. Unlike other founder populations, whose genealogy has been extensively documented, the demographic history of the Gypsies is not fully understood and, given the lack of written records, has to be inferred from current genetic data. In this study, we have used five disease loci harboring private Gypsy mutations to examine some missing historical parameters and current structure. We analyzed the frequency distribution of the five mutations in 832–1,363 unrelated controls, representing 14 Gypsy populations, and the diversification of chromosomal haplotypes in 501 members of affected families. Sharing of mutations and high carrier rates supported a strong founder effect, and the identity of the congenital myasthenia 1267delG mutation in Gypsy and Indian/Pakistani chromosomes provided the best evidence yet of the Indian origins of the Gypsies. However, dramatic differences in mutation frequencies and haplotype divergence and very limited haplotype sharing pointed to strong internal differentiation and characterized the Gypsies as a founder population comprising multiple subisolates. Using disease haplotype coalescence times at the different loci, we estimated that the entire Gypsy population was founded ∼32–40 generations ago, with secondary and tertiary founder events occurring ∼16–25 generations ago. The existence of multiple subisolates, with endogamy maintained to the present day, suggests a general approach to complex disorders in which initial gene mapping could be performed in large families from a single Gypsy group, whereas fine mapping would rely on the informed sampling of the divergent subisolates and searching for the shared genomic region that displays the strongest linkage disequilibrium with the disease.

    The Roma are comprised of many founder groups of common Indian origins but different socio-cultural characteristics. The Vlax Roma are one of the founder Roma populations characterized by a period of bondage in the historic Romanian principalities, and by the archaic Romanian language. Demographic history suggests different migration routes of Roma populations, especially after their arrival in Mesopotamia and the eastern boundary of the Byzantine Empire. Although various genetic studies of uniparental genetic markers showed a connection between Roma genetic legacy and their migration routes, precise sampling of Roma populations elucidates this relationship in more detail. In this study, we analyzed mitochondrial DNA of 384 Croatian Vlax Roma from two geographic locations in the context of 734 European Roma samples. Our results show that Roma migration routes are marked with two Near-Eastern haplogroups, X2 and U3, whose inverse proportional incidence clearly separates the Balkan and the Vlax Roma from other Roma populations that reached Europe as part of the first migration wave. Spatial and temporal characteristics of these haplogroups indicate a possibility of their admixture with Roma populations before arrival in Europe. Distribution of haplogroup M35 indicates that all Vlax Roma populations descend from one single founder population that might even reach back to the original ancestral Indian population. Founder effects followed by strict endogamy rules can be traced from India to contemporary small, local communities, as in the case of two Croatian Vlax Roma populations that show clear population differentiation despite similar origins and shared demographic history.

    Previous genetic, anthropological and linguistic studies have shown that Roma (Gypsies) constitute a founder population dispersed throughout Europe whose origins might be traced to the Indian subcontinent. Linguistic and anthropological evidence point to Indo-Aryan ethnic groups from North-western India as the ancestral parental population of Roma. Recently, a strong genetic hint supporting this theory came from a study of a private mutation causing primary congenital glaucoma. In the present study, complete mitochondrial control sequences of Iberian Roma and previously published maternal lineages of other European Roma were analyzed in order to establish the genetic affinities among Roma groups, determine the degree of admixture with neighbouring populations, infer the migration routes followed since the first arrival to Europe, and survey the origin of Roma within the Indian subcontinent. Our results show that the maternal lineage composition in the Roma groups follows a pattern of different migration routes, with several founder effects, and low effective population sizes along their dispersal. Our data allowed the confirmation of a North/West migration route shared by Polish, Lithuanian and Iberian Roma. Additionally, eleven Roma founder lineages were identified and degrees of admixture with host populations were estimated. Finally, the comparison with an extensive database of Indian sequences allowed us to identify the Punjab state, in North-western India, as the putative ancestral homeland of the European Roma, in agreement with previous linguistic and anthropological studies.

    Rates of aggression and delinquency are assumed to be higher among Roma and other minorities, but sound evidence of this is lacking. Our aim was to assess delinquent and aggressive behavior among Roma and non-Roma adolescents and the effects on ethnic differences of parental education and social desirability. We conducted a cross-sectional study among Roma from separated and segregated settlements in the eastern part of Slovakia (N = 330; Mage = 14.50; interview) and non-Roma adolescents (N = 722; Mage = 14.86; questionnaire). The effect of ethnicity on antisocial behaviors was analyzed using linear regression (crude) and adjusted for gender, parental education, and social desirability. Adjustment for social desirability diminished the ethnic differences in delinquency (B = 1.08; 95% confidence interval [CI] = [2.12, -0.04]), led to an increase in the differences in hostility (B = 2.43; 95% CI = [0.87, 3.99]), and led to the disappearance of differences in physical aggression (B = 0.45; 95% CI = [1.14, 2.07]). Parental education did not affect the associations in an important way. Our findings indicate that Roma are not that much different from non-Roma, in terms of antisocial behavior, which contradicts the general perception of Roma. Our findings should be confirmed in other settings. PMID:25381268

    Objective The Roma minority represents the largest ethnic group in Central and South-East European countries. Data regarding the mortality in Roma hemodialysis subjects are limited. We evaluated the 3 year mortality of ESRD Roma patients treated with hemodialysis (HD). Study Design and Setting Our prospective cohort study included 600 ESRD patients on HD therapy recruited from 7 HD centers, from the main geographical regions of Romania. The median age of the patients was 56 (19) years, 332 (55.3%) being males, 51 (8.5%) having Roma ethnicity. Results Roma ESRD patients initiate dialysis at a younger age, 47.8 years vs. 52.3 years (P = 0.017), present higher serum albumin (P = 0.013) and higher serum phosphate levels (P = 0.021). In the Roma group, the overall 3 year mortality was higher when compared to Caucasians (33.3% vs. 24.8%). The multivariate survival analysis revealed that being of Roma ethnicity is an independent risk factor for mortality (HR = 1.74; 95% CI = 1.04–2.91; P = 0.035). Conclusions Roma patients with ESRD initiate HD therapy at a younger age as compared to Caucasians. They have a higher 3 year mortality rate and are dying at a younger age. Roma ethnicity represents an independent risk factor for mortality in our cohort. PMID:27196564

    2012-04-01

    The Roma constitute the largest ethnic minority in the European Region. The many policy initiatives designed over the past two decades to tackle their adverse social conditions in Central and South Eastern Europe, where the Roma population is concentrated, have had limited success. This paper reviews what is being done to improve the health and social situation of Roma communities in the Region and identifies factors that may limit the effectiveness of these policy initiatives. Strong political commitment, measures to overcome prejudices against Roma, inter-sectoral policy coordination, adequate budgets, evidence-based policies, and Roma involvement can be identified as key preconditions for improved health outcomes and well-being. However, developing a sound evidence-based approach to Roma inclusion requires removing obstacles to the collection of reliable data and improving analytical and evaluation capacity. Health policies seeking to reduce health inequalities for Roma people need to be aligned with education, economic, labour market, housing, environmental and territorial development policies and form part of comprehensive policy frameworks allowing for effective integration.

    The authors discuss the clinical and molecular genetic aspects of genetically determined neuromuscular disorders of some Roma families living in Hungary. Among the autosomal recessively inherited spinal muscular atrophic (SMA) group, 8 Caucasian children had the typical 7-8 exonal deletions of the SMA gene, but only 2 patients belonged to the Roma population. There was no difference in the molecular genetic findings among the Caucasian and the Roma SMA patients. All of them had 7-8 exonal deletions of the SMA gene. We wanted to call attention to the founder mutation of the Roma population in 7 patients suffering from congenital myasthenia (CMS) from 3 Roma families. The 1267G deletion for CMS was detected by molecular genetic method. Clinical onset was pubertal and relatively slow progression of specific and phenotypic features for this founder mutation of acetyl-cholin receptor epsylon gene. In 2 patients (sister and brother) the sarcoglycanopathy 2C type C283Q mutation was proven in one Roma family suffering from limb-girdle muscular dystrophy (LGMD). Two out of the three facioscapular-humeral dystrophy (FSHD) Roma families carried 21.8 kb and 18.5 kb alleles in FSHD A1 gene (D4S139). In one family together with prenatal diagnosis founder mutation in FSHD A1 gene was detected, according to the autosomal dominant (AD) inheritance. In (F2) prenatal diagnosis was carried out, 18.5 kb/18.5 kb homozygosity was proven in the fetus, so the pregnancy was interrupted. In the CMS, LGMD and FSHD Roma patients ancient typical Roma founder mutations were found. PMID:19248726

    Marginalised Roma communities in European countries live in substandard housing conditions the improvement of which has been one of the major issues of the Decade of Roma Inclusion, the ongoing intergovernmental European Roma programme. The paper presents EU-funded health impact assessments of national Roma housing policies and programmes in 3 Central and Eastern European countries in light of the evaluation of a completed local project in a fourth CEE country so as to compare predicted effects to observed ones. Housing was predicted to have beneficial health effects by improving indoor and outdoor conditions, access to services, and socioeconomic conditions. Negative impacts were predicted only in terms of maintenance expenses and housing tenure. However, observed impacts of the completed local project did not fully support predictions especially in terms of social networks, satisfaction with housing and neighbourhood, and inhabitant safety. In order to improve the predictive value of HIA, more evidence should be produced by the careful evaluation of locally implemented housing projects. In addition, current evidence is in favour of planning Roma housing projects at the local rather than at the national level in alignment with the principle of subsidiarity. - Highlights: Black-Right-Pointing-Pointer Predictive validity of HIA of national Roma housing policies - in light of current evidence - is low. Black-Right-Pointing-Pointer Implemented housing projects should be comprehensively evaluated to improve reliability of HIA. Black-Right-Pointing-Pointer Roma housing projects should be planned at the local rather than at the national level. Black-Right-Pointing-Pointer HIA should be used to plan Roma housing projects at the local level.

  3. ROMA: Representation and Quantification of Module Activity from Target Expression Data

    2016-01-01

    In many analyses of high-throughput data in systems biology, there is a need to quantify the activity of a set of genes in individual samples. A typical example is the case where it is necessary to estimate the activity of a transcription factor (which is often not directly measurable) from the expression of its target genes. We present here ROMA (Representation and quantification Of Module Activities) Java software, designed for fast and robust computation of the activity of gene sets (or modules) with coordinated expression. ROMA activity quantification is based on the simplest uni-factor linear model of gene regulation that approximates the expression data of a gene set by its first principal component. The proposed algorithm implements novel functionalities: it provides several method modifications for principal components computation, including weighted, robust and centered methods; it distinguishes overdispersed modules (based on the variance explained by the first principal component) and coordinated modules (based on the significance of the spectral gap); finally, it computes statistical significance of the estimated module overdispersion or coordination. ROMA can be applied in many contexts, from estimating differential activities of transcriptional factors to finding overdispersed pathways in single-cell transcriptomics data. We describe here the principles of ROMA providing several practical examples of its use. ROMA source code is available at https://github.com/sysbio-curie/Roma. PMID:26925094

    On average, the Roma in Europe can expect to die 10 years earlier than the rest of the population, given the health conditions they experience. EU-funded research has informed on successful actions (SA) that when implemented among the Roma provide them new forms of educational participation which have a direct impact on improving their health status, regardless of their educational level. The findings from this research, unanimously endorsed by the European Parliament, have been included in several European Union recommendations and resolutions as part of the EU strategy on Roma inclusion. To analyze these SA, as well as the conditions that promote them and their impact on reducing health inequalities, communicative fieldwork has been conducted with Roma people from a deprived neighbourhood in the South of Spain, who are participating in the previously identified SA. The analysis reveals that these SA enable Roma people to reinforce and enrich specific strategies like improving family cohesion and strengthening their identity, which allow them to improve their overall health. These findings may inform public policies to improve the health condition of the Roma and other vulnerable groups, one goal of the Europe 2020 strategy for a healthier Europe. PMID:23887619

    This study investigates intergeneration transmission of ethnic identity as a resource for life satisfaction of Roma adolescents and their parents. Historically, Roma represent the largest ethnic minority in Europe. They have been exposed to severe discrimination, social exclusion, and poverty. Therefore, identifying resources for their life satisfaction is theoretically and practically important. The present study included 1093 participants, of which there were 171 Roma adolescents (age: M = 14.96 years, SD = 1.85), 155 mothers (age: M = 36.16 years, SD = 5.77) and 123 fathers (age: M = 39.68 years, SD = 6.06). Further, a comparison group of 248 mainstream adolescents with their mothers (n = 221) and fathers (n = 175) was also included in the study. Adolescents and their parents provided data on ethnic identity (MEIM; Phinney, 1992) and life satisfaction (SWLS; Diener, Emmons, Larsen, & Griffin, 1985). Results indicated that Roma youth were lower on endorsement of ethnic identity and average on life satisfaction compared to their mainstream peers. A structural equation model showed that ethnic identity was a positive predictor of life satisfaction for both adolescents and their Roma parents. Furthermore, parents' ethnic identity was a predictor of adolescent life satisfaction. We concluded that for Roma youth and their parents, ethnic identity represents a salient source for life satisfaction and an intergenerational continuity of identity and life satisfaction exists.

    The European Roma represent a transnational mosaic of minority population groups with different migration histories and contrasting experiences in their interactions with majority populations across the European continent. Although historical genetic contributions of European lineages to the Roma pool were investigated before, the extent of contemporary genetic admixture between Bayash Roma and non-Romani majority population remains elusive. The aim of this study was to assess the genetic structure of the Bayash Roma population from northwestern Croatia and the general Croatian population and to investigate the extent of admixture between them. A set of genetic data from two original studies (100 Bayash Roma from northwestern Croatia and 195 individuals from the general Croatian population) was analyzed by Bayesian clustering implemented in STRUCTURE software. By re-analyzing published data we intended to focus for the first time on genetic differentiation and structure and in doing so we clearly pointed to the importance of considering social phenomena in understanding genetic structuring. Our results demonstrated that two population clusters best explain the genetic structure, which is consistent with social exclusion of Roma and the demographic history of Bayash Roma who have settled in NW Croatia only about 150 years ago and mostly applied rules of endogamy. The presence of admixture was revealed, while the percentage of non-Croatian individuals in general Croatian population was approximately twofold higher than the percentage of non-Romani individuals in Roma population corroborating the presence of ethnomimicry in Roma.

    2016-01-01

    Ovarian cancer is a common malignancy of the female reproductive system. Tumor markers serve as tools in the diagnosis of the disease. The aim of the present study was to determine the diagnostic value of sera levels of carbohydrate antigen-125 (CA-125), human epididymis protein 4 (HE4) as well as the area under the curve of the receiver operating characteristic (ROC) and the risk of ovarian malignancy algorithm (ROMA) index in ovarian cancer. The sera were measured using an electrochemiluminescence immunoassay on 158 individuals (64 patients with ovarian cancer, 64 with ovarian benign tumor and 30 healthy individuals) between September 2013 and May 2015. The results showed that levels of HE4 and CA-125 in the sera of the ovarian benign tumor group as well as their ROMA index were significantly higher (P<0.05) than those of the ovarian benign tumor and control groups, regardless of pre- or postmenopausal status. However, the level of CA-125 was significantly higher (P<0.05) in the ovarian benign tumor group compared with the healthy group, while the level of HE4 was similar in the two groups. The sensitivity of the ROMA index was higher (P<0.01) with detection of HE4 and CA-125. In the ovarian cancer group, the areas under ROC curves of ROMA, HE4 and CA-125 were 0.994, 0.990 and 0.941, respectively. The specificity and positive predictive value of HE4 in the premenopausal ovarian cancer group reached 98.36 and 95%, respectively. In conclusion, the results showed that the serum level of HE4 and the ROMA index are important indicators in the diagnosis of ovarian cancer. However, in addition to HE4 and CA-125 detection, the ROMA index is extremely valuable in improving the diagnostic efficiency of ovarian cancer. PMID:27347403

    2015-01-01

    Background In the present study we aimed: 1) To establish the prevalence and clinical impact of DFNB49 mutations in deaf Roma from 2 Central European countries (Slovakia and Hungary), and 2) to analyze a possible common origin of the c.1331+2T>C mutation among Roma and Pakistani mutation carriers identified in the present and previous studies. Methods We sequenced 6 exons of the MARVELD2 gene in a group of 143 unrelated hearing impaired Slovak Roma patients. Simultaneously, we used RFLP to detect the c.1331+2T>C mutation in 85 Hungarian deaf Roma patients, control groups of 702 normal hearing Romanies from both countries and 375 hearing impaired Slovak Caucasians. We analyzed the haplotype using 21 SNPs spanning a 5.34Mb around the mutation c.1331+2T>C. Results One pathogenic mutation (c.1331+2T>C) was identified in 12 homozygous hearing impaired Roma patients. Allele frequency of this mutation was higher in Hungarian (10%) than in Slovak (3.85%) Roma patients. The identified common haplotype in Roma patients was defined by 18 SNP markers (3.89 Mb). Fourteen common SNPs were also shared among Pakistani and Roma homozygotes. Biallelic mutation carriers suffered from prelingual bilateral moderate to profound sensorineural hearing loss. Conclusions We demonstrate different frequencies of the c.1331+2T>C mutation in hearing impaired Romanies from 3 Central European countries. In addition, our results provide support for the hypothesis of a possible common ancestor of the Slovak, Hungarian and Czech Roma as well as Pakistani deaf patients. Testing for the c.1331+2T>C mutation may be recommended in GJB2 negative Roma cases with early-onset sensorineural hearing loss. PMID:25885414

    2014-02-01

    To assess how specific population history, different migration routes, isolation, and endogamy practices contributed to the distribution of several rare diseases found in specific Roma groups, we conducted a population-based research study of rare disease mutations in Croatian Vlax Roma. We tested a total of 427 subjects from Baranja and Međimurje for the presence of four mutations causing hereditary motor and sensory neuropathy type Lom (HMSNL), GM1 gangliosidosis (GM1), congenital cataracts, facial dysmorphism and neuropathy (CCFDN), and limb girdle muscle dystrophy type 2C (LGMD2C), using the RFLP-PCR method to estimate carrier frequencies. We identified a total of four individuals heterozygous for the mutation causing HMSNL in the Baranja population, with a carrier rate amounting to 1.5%. Carriers for other three mutations causing GM1, CCFDN, and LGMD2C were not found in our sample. The carrier rate for the HMSNL mutation in Baranja is lower than in other Vlax Roma groups. In addition, distinct differences in carrier rates between the Croatian Vlax groups point to different genetic history, despite their belonging to the same Roma migration category and subgroup. The difference in carrier rates is either the result of admixture or the reflection of a greater extent of genetic drift since recent founding, maintained by a high degree of endogamy. PMID:24180318

    In most cases, discussions on the right to education focus on the way access to education can be warranted for all and which aims should be pursued in rather abstract terms. This article approaches the topic starting from the case of Roma people. The particularity of their living circumstances raises the question what it is that we are aiming at…

    Researches into health inequalities consistently show disadvantages in health status, morbidity and mortality for various ethnic minority groups. Current knowledge about prevention of cardiovascular diseases (CVD) mainly derives from studies carried out in populations of European origin while the evidences involving Roma population are scarce. Roma, an ethnic minority of northern Indian origin, live in many countries throughout the world and are well known for preserved traditions and resistance to assimilation. They are most often marginalized economically, spatially, politically and in terms of culture. In order to assess the health status and health-related lifestyle attributes, a multidisciplinary anthropological and epidemiological community-based study was carried out including a total of 423 members of the Bayash Roma minority population living in two regions of Croatia (144 men and 279 women, aged 18-84 yrs). Hypertension (HT) was found in 24.8% Bayash Roma (21.5% men and 26.5% women) using standard diagnostic criteria (i.e. BP > or = 140/90 mm Hg or taking antihypertensive therapy). The prevalence increases from 5.9% in the age group 18-34 yrs; 35.0% in the age group 35-64 yrs, and 51.4% in the age group 65+ yrs. The prevalence of hypertension in the Bayash Roma is almost half of the magnitude of what is usually reported for the general population of Croatia. It is also lower when compared with other European populations and this finding is not due to comparatively younger average age of the Bayash sample. The significant association of hypertension with age and BMI was confirmed in this study and the importance of non-traditional SES-related CVD risk factors was highlighted. Smoking is a part of traditional Roma life-style and with 70% of smokers almost the entire population is equally exposed to this risk factor in their family environment. Since homogenously distributed, this risk factor did not show to be a significant predictor of hypertension. The

    The Roma-BZCAT is structured in two parts. Part 1, at present the only one available on-line, contains the lists of blazars, which are classified in three main groups, according to their spectral properties. Each blazar is identified by a three-letter code, where the first two are BZ for blazar and the third one specifies the type, followed by the truncated equatorial coordinates (J2000). The codes are defined in the "Note (G1)" below. (2 data files).

    We describe a new caprine form from the Upper Vallesian of La Roma 2 (Teruel Basin, Aragon). Aragoral mudejar Gen.n., sp.n. is close to the primitive forms of the Hippotraginae-Caprinae group. It differs from Norbertia hellenica by its more primitive dentition, the greater separation between the bases of the horn cores, the decreased thickness of the frontal bone and the relatively smaller size of the horn cores.

    2008-11-30

    Recent medical genetic research has identified a number of novel, or previously known, but rare conditions, caused by private founder mutations. The Finnish and Ashkenazi Jew populations provide the best examples for identifying genes in unique genetic disorders. In these populations, research efforts and high-level medical services resulted in intense improvements of medical care and in organization of population-based screening programs. Hereditary disorders of the Roma populations are known for a long time. The genetic background of these diseases has been established by extensive molecular genetic studies. The Romas represent 6% of the Hungarian population and live under extremely bad health conditions. Therefore, our aim was to map the incidence of the hereditary neuromuscular disorders among the Hungarian Roma population. Moreover, we intended to provide proper information, genetic counseling and possible prevention strategies for the families at risk, which should represent a primer task in public health. Because of our experience in neuromuscular disorders, we choose six, frequent, autosomal recessive disorders for these clinical and genetic studies: hereditary motor and sensory neuropathy type Lom (HMSNL), hereditary motor and sensory neuropathy type Russe (HMSNR), congenital cataracts facial dysmorphism syndrome (CCFDN), limb-girdle muscular dystrophy 2C (LGMD2C), congenital myasthenic syndrome (CMS) and spinal muscular atrophy (SMA). Following identification of the founder mutations, the possibility of prenatal diagnosis and carrier screening for family members will contribute to the decrease of the recurrence risk for these severe, mostly untreatable disorders.

    Learning and gaining knowledge of Roman history is an area of interest for students and citizens at large. This is an example of a subject with great sweep (with many interrelated sub-topics over, in this case, a 3,000 year history) that is hard to grasp by any individual and, in its full detail, is not available as a coherent story. In this paper, we propose a visual analytics approach to construct a data driven view of Roman history based on a large collection of Wikipedia articles. Extracting and enabling the discovery of useful knowledge on events, places, times, and their connections from large amounts of textual data has always been a challenging task. To this aim, we introduce VAiRoma, a visual analytics system that couples state-of-the-art text analysis methods with an intuitive visual interface to help users make sense of events, places, times, and more importantly, the relationships between them. VAiRoma goes beyond textual content exploration, as it permits users to compare, make connections, and externalize the findings all within the visual interface. As a result, VAiRoma allows users to learn and create new knowledge regarding Roman history in an informed way. We evaluated VAiRoma with 16 participants through a user study, with the task being to learn about roman piazzas through finding relevant articles and new relationships. Our study results showed that the VAiRoma system enables the participants to find more relevant articles and connections compared to Web searches and literature search conducted in a roman library. Subjective feedback on VAiRoma was also very positive. In addition, we ran two case studies that demonstrate how VAiRoma can be used for deeper analysis, permitting the rapid discovery and analysis of a small number of key documents even when the original collection contains hundreds of thousands of documents.

  11. The Prodigies of The Albano Lake During Roman Age and Natural Hazard Assessment At Roma, Italy.

    NASA Astrophysics Data System (ADS)

    Funiciello, R.; Giordano, G.; de Rita, D.

    Roma is built just 20 km to the northwest of the Pleistocene Colli Albani volcano, but is believed not exposed to relevant natural hazards, except for the Tiber river flood- ings, and local amplification of seismic waves from distal earthquakes. This belief has generally induced modern historians and geologists to discard as SmythologicalT the & cedil;many references to natural prodigies that are reported by many Roman-age historians. Recent studies have demonstrated that the Albano maar, the youngest volcanic cen- tre of the Colli Albani volcano and presently filled by a 175 m deep lake, protracted its activity to the Holocene triggering several catastrophic lahar events, likely related to lake withdrawal, the deposits of which are exposed to the southwest of Roma and reach its periphery. This finding youngs the history of the volcano and makes it rele- vant to pre-historic settlements, which ScarefullyT avoided the Albano maar slopes up & cedil;to the Bronze age. What is still unknown, though, is whether the lake experienced such fluctuations and overspills during historic times. Several Roman authors such as Ti- tus Livius, Dionigi d'Alicarnasso, Plutarco, Germanico, and many others wrote about the then well known 398 BC prodigious event, when, during the war between Roma and the Etruscan city of Veio, the gods anger caused the sudden rise and overspill of the Albano lake, reported as unrelated to climatic events, and the destructive flooding of the countryside. After that event Romans actually built a tunnel-drain which still operates regulating the lake level at 293 m a.s.l., 70 m below the maar rim elevation. Should those chronicles be truthful, we can join the geologic observation of Holocene lahar deposits from lake withdrawal with historical lake withdrawals, reassessing the natural hazard for the city of Roma under a point of view never explored before. This paper carefully explores the historical credibility of the 398 BC lake overspill event and its

    This article examines the degree of integration of Roma and Gypsy children in formal education in the Peloponnese region of Greece. It is based on field research conducted by the University of Patras during the school year 2006/07 within the framework of the Greek Ministry of Education's "Integration of Roma children in school" programme, funded by the European Union. Despite governmental incentives for poor families to enrol their school-aged children, school attendance of Roma and Gypsy children was found to decline from primary year one to primary year six, with hardly any of them entering secondary school at all. Besides looking at school attendance figures and Roma and Gypsy children's proficiency in reading, writing and numeracy, this paper also considers gender, family composition, living conditions and economic situation, as well as culturally constructed perceptions of childhood and a person's life cycle. The aim of this article is to highlight the contradictions and ambiguities involved in the process of incorporating Roma and Gypsy children in formal education, and to evaluate their school performance and assess their academic choices.

    2012-01-01

    Background: Estimated number of the Roma people in central-eastern Europe cannot be precisely appreciated, but official data suggest that in the 2004 they were approximately 4.2 million. At this time, there are few available data about the health status of the Roma people, mostly assessing genetic and infectious diseases, which reflect poverty, overcrowding, and lack of education. There is even less data regarding non–communicable and chronic diseases, especially cardiovascular diseases. Methods: We searched the published literature on the cardiovascular risk factors in Roma people using PubMed from January 2000 to July 2011. The searching criteria were: (1) randomized, prospective observational, retrospective and meta-analysis; (2) adult patients with cardiac diseases or cardiovascular risk factors (3) data available for cardiovascular patients. Search terms included dyslipidemia, obesity, tobacco, hypertension, and diabetes mellitus. Results: Twenty-five studies were identified. Approximately 75% of them were related to just four countries: Slovakia, Croatia, Czech Republic, and Serbia. This paper is a review based on existing literature concerning classical risk factors in Roma people with emphasis on their ethnical features. Despite limited data, the results showed that this ethnicity has the incriminated risk factors more frequently than the majority and consequently a higher cardiovascular morbidity rate. Conclusions: Quantification of the cardiovascular risk factor and their implication in the shortening of life expectancy in Roma population was a provocation due to a paucity of reliable data. At this time, we should pay more attention on the Roma health issues and the cultural concerns that might affect them in the context of borderless Europe. PMID:23390466

    Objectives Health-related quality of life (HRQoL) measures a patient’s subjective experience of his or her health status. We aimed to show how the presence of chronic diseases and satisfaction with family physicians (FPs) were associated with the HRQoL of a Roma population. Methods A cross-sectional study was carried out in May 2011 on a representative sample of 650 Roma living in Prekmurje, Slovenia. The EQ-5D questionnaire was used for measuring the HRQoL of the Roma. Demographical data, 12 groups of diseases diagnosed in the last 12 months and satisfaction with FPs were included in the questionnaire. Results The response rate was 88.3% 574), of which 56.4% were female, and the average age of the participants had a mean value of 40.2±12.7 years. The presence of cardiovascular problems with risk factors for them or presence of musculoskeletal disorders were strongly associated with the presence of pain (Cramer’s V = 0.40 and 0.46 respectively). There was a strong association between the presence of mental disorders and anxiety and depression (Cramer’s V = 0.58). The average satisfaction with the family physician was 3.9 (mean±1.10) on a five-point Likert scale. There was no significant association between HRQoL and satisfaction with the family physician. Conclusions Roma with chronic mental health problems had the lowest HRQoL in the Roma population. More attention should be paid to this subgroup of Roma in family medicine, and interventions should be provided. High satisfaction with their FPs is not associated with the observed quality of life variables.

    The paper discusses the necessity to bring environmental equity within the Pata Rât Roma community in Northwest Romania, relying on the answers to three questions: "Does environmental equity exist in Pata Rât?", "How can it be attained?", and "To what extent can it be brought to the targeted people?" It was shown how a trio of factors tailors the destiny of Roma inhabitants: being a minority, their ethnicity, and the fact they are living on and off what society rejects and dumps-a landfill. The framing of the environmental equity concerns within a vision considering negotiation as the most adequate means to attain it is a novel approach. Further on, the results of the study can fuel win-win solutions in environmental equity. The information abstracted from a set of indicators, assessed through an evaluation matrix, represents a beneficial platform for future bottom-up decisions concerning landfill residents. Three action options were analyzed: on-site living opportunities-that resulted to be preferred, off-site living opportunities, and "Do nothing". The analysis provides qualitative evidence that the evaluation of environmental equity is largely subjective, because of its complexity and specificity related to geographical, historical, cultural characteristics, and political interests.

    Taxanes are widely used microtubule-stabilizing chemotherapeutic agents in the treatment of cancers. Several cytochrome P450 gene variants have been proven to influence taxane metabolism and therapy. The purpose of this work was to determine the distribution of genetic variations of CYP1B1, CYP2C8 and CYP3A5 genes as the first report on taxane metabolizer cytochrome P450 gene polymorphisms in Roma and Hungarian populations. A total of 397 Roma and 412 Hungarian healthy subjects were genotyped for CYP1B1 c.4326C > G, CYP2C8 c.792C > G and CYP3A5 c.6986A > G variant alleles by PCR-RFLP assay and direct sequencing. We found significant differences in the frequencies of homozygous variant genotypes of CYP1B1 4326 GG (p = 0.002) and CYP3A5 6986 GG (p < 0.001) between Roma and Hungarian populations. Regarding minor allele frequencies, for CYP2C8 a significantly increased prevalence was found in 792G allele frequency in the Hungarian population compared to the Roma population (5.83% vs. 2.14%, p = 0.001). Our results can be used as possible predictive factors in population specific treatment algorithms to developing effective programs for a better outcome in patients treated with taxanes.

    We assessed the prevalence of HIV and selected blood-borne and sexually transmitted infections among a convenience sample of 64 residents of Dzsumbuj, a predominantly Roma (Gypsy) neighbourhood in Budapest, Hungary. No cases of HIV were detected, while the prevalence of Hepatitis B infection (anti-HBc) was 27% and syphilis prevalence was 2%. Romas (n=50) were significantly more likely than non-Romas (n=14) to have HAV antibodies (80% vs. 43%) and less likely to be HBV immunized (anti-HBs only; 6% vs. 29%). Current drug injectors (n=13) were more likely than non-injectors (n=51) to have antibodies against HAV (85% vs. 69%) and HCV (85% vs. 8%). While HIV has not been introduced in this population, risk conditions for a potentially explosive HIV epidemic are present. Health care policies should focus on expanding coverage for HAV and HBV immunizations, and access to HIV preventive services needs to be extended to marginalized, mostly minority populations, such as the Roma in Europe.

    Background During implementation of a community development project involving a severely disadvantaged Roma community, the community was threatened with eviction. Two scenarios, eviction with placement on the waiting list for social housing versus a replacement housing development, were identified and specified. A health impact assessment (HIA) was carried out to inform subsequent negotiations. Aims To assess the health effects of eviction in comparison with that of a housing project for a Roma community; to make recommendations on short‐term and long‐term benefits of the two scenarios in order to inform the local government; and to develop a demonstration HIA that can act as a model for other disadvantaged Roma populations. Method A prospective assessment, based on a broad model of health, was carried out to assess health effects of a housing project compared with eviction. By design, it ensured full involvement of members of the community, local decision makers and relevant stakeholders. Results and conclusion This HIA identified numerous positive and some probable negative health effects of a housing project. Despite the uncertainty around some of its predicted effects, the overall health benefit of a housing project clearly outweighed that of eviction. Although the immediate financial advantages of eviction for the municipal government are clear, this example provides further evidence to support the adoption of a statutory requirement to assess both economic and health outcomes. It also provides an example that other Roma communities can emulate. PMID:17933953

    A measles outbreak occurred from November 2015 to April 2016 in two northern Italian regions, affecting the Roma/Sinti ethnic population and nosocomial setting. Overall, 67 cases were reported. Median age of 43 cases in three Roma/Sinti camps was four years, nosocomial cases were mainly adults. The outbreak was caused by a new measles virus B3.1 variant. Immunisation resources and strategies should be directed at groups with gaps in vaccine coverage, e.g. Roma/Sinti and healthcare workers. PMID:27240004

    PubMed

    Pnevmatikos, Dimitris; Geka, Maria; Divane, Maria

    2010-12-01

    This study investigates the emergence, development and structure of ethnic identity during childhood. Forty Roma children living in Greece aged between 2.8 and 11.9 years answered questions about their awareness/recognition of four aspects of their ethnic identity-namely place of habitation, traditional costumes, the Roma language, and early betrothal of children-their identity and their sense of stability and constancy. The study also investigates how the children feel about the abandonment of those four aspects. The evidence from the current data supports the hypothesis that awareness of ethnic identity emerges before the age of 4. Moreover, this study offers direct empirical evidence of the multidimensionality of ethnic identity. A model of three concentric rings is proposed, extending from a core containing the most highly valued aspects of ethnic identity to the outer annulus that comprises the nonpermanent and nonstable aspects of ethnic identity. The aspects in each annulus differ in terms of the development of the sense of stability and constancy and the feelings associated with loss of the aspects in question. Even the youngest participants considered the aspects in the core to be stable and constant as well as emotionally charged; and even the 11-year-olds did not consider the aspects contained in the outer, more fluid annulus as stable and constant aspects of their ethnic identity. The development of an aspect is determined by what the majority of adults in a society, at a particular time in history, consider to be most important. PMID:22044083

  4. The KRAB Zinc Finger Protein Roma/Zfp157 Is a Critical Regulator of Cell-Cycle Progression and Genomic Stability

    Summary Regulation of DNA replication and cell division is essential for tissue growth and maintenance of genomic integrity and is particularly important in tissues that undergo continuous regeneration such as mammary glands. We have previously shown that disruption of the KRAB-domain zinc finger protein Roma/Zfp157 results in hyperproliferation of mammary epithelial cells (MECs) during pregnancy. Here, we delineate the mechanism by which Roma engenders this phenotype. Ablation of Roma in MECs leads to unscheduled proliferation, replication stress, DNA damage, and genomic instability. Furthermore, mouse embryonic fibroblasts (MEFs) depleted for Roma exhibit downregulation of p21Cip1 and geminin and have accelerated replication fork velocities, which is accompanied by a high rate of mitotic errors and polyploidy. In contrast, overexpression of Roma in MECs halts cell-cycle progression, whereas siRNA-mediated p21Cip1 knockdown ameliorates, in part, this phenotype. Thus, Roma is an essential regulator of the cell cycle and is required to maintain genomic stability. PMID:27149840

    Aims: Hereditary as well as acquired thrombophilia is associated with a higher incidence of severe obstetric complications such as preeclampsia, spontaneous pregnancy loss, placental abruption, and fetal growth retardation. The aim of our study was to examine the association of selected thrombophilic polymorphisms (factor V Leiden, MTHFR C677T, and MTHFR A1298C) with pregnancy complications in the Slovak majority population and the Roma (Gypsy) ethnic population. The study included 354 women; 120 patients and 105 controls from the Slovak majority population, 50 patients and 79 controls from the Slovak Roma population. Genotyping was performed by the real-time polymerase chain reaction method using TaqMan® MGB probes. Results: A statistically significant higher frequency of factor V Leiden (p=0.001, odds ratio [OR]=5.9) and MTHFR C677T polymorphism (p=0.011, OR=1.7) was observed in the Slovak majority patient group compared to the control group. The incidence of MTHFR A1298C polymorphism between patients and controls did not differ significantly. None of the three polymorphisms studied was in association with pregnancy complications in the group of Roma women. Conclusions: Our study has confirmed the variable distribution of selected thrombophilic polymorphisms in different ethnic groups as well as their various effects on the clinical phenotype.

    Medical communication in Western-oriented countries is dominated by concepts of shared decision-making and patient autonomy. In interactions with Roma patients, these behavioral patterns rarely seem to be achieved because the culture and ethnicity have often been shown as barriers in establishing an effective and satisfying doctor-patient relationship. The study aims to explore the Roma's beliefs and experiences related to autonomy and decision-making process in the case of a disease with poor prognosis. Forty-eight Roma people from two Romanian counties participated in semi-structured interviews, conducted by a research team from the University of Medicine and Pharmacy of Iasi. Participants were recruited among the chronically ill patients and caregivers. The Roma community opposes informing the terminal patients about their condition, the "silence conspiracy" being widely practiced. The family fully undertakes the right of decision making, thus minimizing the patient's autonomy. We identified ethical dilemmas concerning autonomy, lack of patients' real decision-making power, and paternalistic attitudes exerted firstly by the family and, on demand, by the physician. Instead, the Roma patient benefits from a very active support network, being accompanied at the hospital by numerous relatives. The patient's right to make autonomous decisions promoted in the Western countries and stipulated by the Romanian law has diminished value in the Roma community. For the Roma, the understanding of dignity is not simply individual and personal, but it is closely related to their cultural particularities. Ignoring their cultural values could create conflicts between healthcare providers and community. PMID:22752639

    Curcuma longa (Zingiberaceae) is known for its uses in medicine, cosmetics, food flavouring and textile industries. The secondary metabolites of turmeric like essential oil, oleoresin and curcumin are important for its multipurpose uses. These traits of turmeric vary from place to place due to the influence of environment, soil and agro-climatic conditions. Here, we analyzed turmeric from different agroclimatic regions for influence of various factors on its growth and yield of important phytochemicals. A high curcumin yielding cultivar i.e., Roma was collected from high altitude research station, Koraput (HARS) and planted in nine agroclimatic regions of Odisha. Analysis of soil texture, pH, organic carbon, micro and macro nutrients were done from all the studied zones up to 2nd generation. Plants grown in their released station i.e., Eastern Ghat High Land showed 5% of curcumin and were taken as control. Plants grown in different agroclimatic zones showed a range of 1.4-5% of curcumin and 0.3-0.7% of rhizome essential oil and 0.3-1% of leaf essential oil content. Gas chromatography and mass spectra analysis showed tumerone and alpha phellandrene as the major compounds in all the zones with 10-20% variation. The present study will be immensely helpful for standardization and management of environmental and ecological factors for high phytochemical yield in turmeric plant. PMID:26155681

  8. Rank-Ordered Multifractal Analysis (ROMA) of Intermittent Dissipative Structures in Solar Corona

    Rank-Ordered Multifractal Analysis (ROMA) was introduced by Chang and Wu (2008) to describe the multifractal characteristic of intermittent events. The procedure provides a natural connection between the rank-ordered spectrum and the idea of one-parameter scaling for monofractals. This technique has successfully been applied to fluid turbulence, MHD turbulence simulations and turbulence data obtained in various space plasmas. In this paper, the technique is applied to an extended data set of extreme ultraviolet images of the solar corona provided by the extreme ultraviolet imaging telescope (EIT) on board the SOHO spacecraft. The data set was shown by Uritsky et al. (2007) to exhibit coexistence of self-organized criticality and intermittent turbulence. In this study, the SOHO EIT data set is shown to include two multifractal rank-ordered regimes, dependent on spatial scales, which may indicate different physical mechanisms of energy dissipation in the solar corona corresponding to meso- and supergranulation scales of the underlying photospheric network. This crossover behavior of the ranked-order regimes is similar to the characteristics observed by Tam et al. (2010) of the auroral zone electric-field fluctuations.

    The hallmark of nonlinear complexity phenomena in plasmas as well as in all natural sciences is the appearance of intermittent fluctuating events. Such intermittent fluctuations are the results of the dynamic interactions of multiple coherent structures of varied sizes in stochastic media. We discuss here a unique procedure, the Rank-Ordered Multifractal Analysis (ROMA), that is both physically explicable and quantitatively accurate in deciphering the multifractal characteristics of intermittency. The generic character of the procedure provides a natural connection between the implicit spectrum based on parametric rank ordering and the one-parameter scaling idea of monofractals. Such an implicit multifractal spectrum has several advantages over the results obtainable using the conventional structure functions. Firstly, the utility of the spectrum is to fully collapse the unscaled PDFs. Secondly, the physical interpretation is clear. It indicates how intermittent the scaled fluctuations are once the spectrum is given. Thirdly, the determination of the values of the fractal nature of the grouped fluctuations is not affected by the statistics of other fluctuations that do not exhibit the same fractal characteristics. The method has been used to study results obtained from large-scale incompressible fluid simulations and large-scale MHD simulations as well as observations of the magnetic field fluctuations of the solar wind, the extreme ultraviolet emissions of the solar corona, and the broadband electric field fluctuations in the auroral zone. The method and some of these applications will be presented.

    Vatastheela is a disease of Mutravahasrotasa, one among the 12 types of Mutraghata disorders elaborated by Sushruta in his seminal work, the Sushruta Samhita. Vatastheela, as described in Ayurveda, closely resembles benign prostatic hyperplasia (BPH) of modern medicine in its signs and symptoms. It is a senile disorder and chiefly affects individuals above the age of 40 years. The symptoms are those of bladder outflow obstruction, with increased frequency of micturition, dribbling, hesitancy, and the features of chronic urinary retention. Surgical management has been accepted as the standard management but is associated with many disadvantages as well as complications, which may not be acceptable at this age. Conservative management with modern medicines is also not free from side effects. So, in this age-group, there is a need for much safer alternative method of management. In this regard, many works have been carried out and shown that the Ayurvedic approach, using natural medicines, is a far better approach. We carried out a comparative study of Mahayavanala Roma Kshara (MRK) and Dhanyaka Gokshura Ghrita (DGG), which are the compounds prescribed for Mutraghata in Ayurvedic literature. The patients were randomly selected from the OPD and IPD of IPGT and RA hospital, Jamnagar, Gujarat, and divided into two groups. In first group, one (500 mg) capsule of MRK was given twice a day with lukewarm water for 45 days; in second group, 10 gm of DGG was given orally twice a day with lukewarm water for 45 days. DGG showed significantly greater relief in the subjective parameters as per International Prostate Symptoms Score (IPSS) than MRK. However, reduction in the size of the prostate and in the volume of the post-void residual urine was found much better in the MRK group. PMID:22131735

    Roma communities represent the main involved actors in the informal activities in the Balkan regions, especially because the state does not formally recognize them as formal inhabitants. The Roma community in Zavidovici, despite being resident since the beginning of the 20th century, is still considered a marginalized and vulnerable group. They are actively involved in and dependent on the informal solid waste sector. Waste collection is a 'family business', a kind of self-employment and the main source of income for households. Informal recyclers have a central role in the solid waste management system and they recover a significant amount of materials, especially iron, copper, brass, lead and exhausted batteries. Despite the negative fluctuations of the raw material prices, because of the international economic crisis, informal recyclers remain dependent on the waste recycling sector. They are crucial actors in the value chain of recyclables: though they cannot access the final buyers of recyclables, they provide more than 50% of the market to the middle dealers in the Zenica-Doboj Canton. This research activity consists of a deep socio-economic analysis of the informal recyclers' community living in Zavidovici city. In particular, this paper describes the composition and welfare status of informal recyclers' households, the role of informal recyclers in waste collection, the geographical coverage and the related pattern of waste picking, types, volumes and price fluctuations of recyclable materials, and the middle dealers involved in the informal recycling system.

  16. Influence of modified atmosphere and varying time in storage on the irradiation sensitivity of Salmonella on sliced roma tomatoes

    2013-09-01

    Salmonella contamination of tomatoes is a recurrent food safety concern. Irradiation inactivates pathogens on fresh and fresh cut produce. However, the interaction of time in refrigerated storage and modified atmosphere packaging (MAP) may influence the response of pathogens to irradiation. Roma tomatoes were sliced and inoculated with a cocktail of outbreak strains of Salmonella. The inoculated tomatoes were packaged under one of four atmospheres: air, 10/90 O2/N2, 5/95 O2/N2 or 100% N2. The packages were kept in refrigerated storage (10 °C) for various times after inoculation, to simulate the potential time delay between packaging and irradiation treatment. Tomatoes were irradiated immediately (0 h), or after 24 or 48 h in storage. The surviving populations were recovered and enumerated. Irradiation effectively reduced Salmonella at all times. Estimated D10 value (the dose necessary for 1 log reduction) varied significantly among the combinations of time and MAP, ranging from 0.165-0.335 kGy. Tomatoes packaged in air, irradiated at 0 h, had a D10 of 0.165 kGy; all other combinations showed significantly higher D10. Reduced oxygen generally resulted in higher D10 values, with the highest D10 of 0.335 kGy obtained for 100% N2, 0 h. Time in storage pre-irradiation tended to increase D10 for air and 5/95 O2/N2, but not for 10/90 O2/N2 or 100% N2. These results suggest that time required for refrigerated holding of processed Roma tomatoes or shipment to an off-site irradiation service provider may alter the efficacy of irradiation if reduced oxygen MAP is used.

    Investigation of 31 of Roma patients with congenital lactic acidosis (CLA) from Bulgaria identified homozygosity for the R446* mutation in the PDHX gene as the most common cause of the disorder in this ethnic group. It accounted for around 60% of patients in the study and over 25% of all CLA cases referred to the National Genetic Laboratory in Bulgaria. The detection of a homozygous patient from Hungary and carriers among population controls from Romania and Slovakia suggests a wide spread of the mutation in the European Roma population. The clinical phenotype of the twenty R446* homozygotes was relatively homogeneous, with lactic acidosis crisis in the first days or months of life as the most common initial presentation (15/20 patients) and delayed psychomotor development and/or seizures in infancy as the leading manifestations in a smaller group (5/20 patients). The subsequent clinical picture was dominated by impaired physical growth and a very consistent pattern of static cerebral palsy-like encephalopathy with spasticity and severe to profound mental retardation seen in over 80% of cases. Most patients had a positive family history. We propose testing for the R446* mutation in PDHX as a rapid first screening in Roma infants with metabolic acidosis. It will facilitate and accelerate diagnosis in a large proportion of cases, allow early rehabilitation to alleviate the chronic clinical course, and prevent further affected births in high-risk families.

    Introduction Roma (Gypsies), the largest and most disadvantaged ethnic minority group in Europe, are believed to be vulnerable to HIV/AIDS. This study’s aim was to examine HIV risk in 6 Roma male sociocentric networks (n=405 men) in Bulgaria. Methods Participants were interviewed concerning their risk practices and tested for HIV/STDs. Results High-risk sexual behaviors were common. Over 57% of men had multiple sexual partners in the past 3 months. Over one-third of men reported both male and female partners in the past year. Condom use was low. Greater levels of sexual risk were associated with lower intentions and self-efficacy for using condoms, drug use, having male partners, knowing HIV-positive persons, and having higher AIDS knowledge but no prior HIV testing. Two men had HIV infection, 3.7% gonorrhea, and 5.2% chlamydia. Discussion HIV prevention interventions directed toward high-risk social networks of Roma are needed before HIV infection becomes more widely established. PMID:22370730

    Objectives To evaluate the validity and compare the performance of cancer antigen-125 (CA-125), human epididymis protein 4 (HE4), the risk of malignancy index (RMI), and the risk of ovarian malignancy algorithm (ROMA) in the diagnosis of ovarian cancer in patients with ovarian lesions discovered during their preoperative work-up investigations. Methods This prospective, cross-sectional study looked at patients who attended the gynecology department at the Royal Hospital, Muscat, from 1 March 2014 to 30 April 2015, for the evaluation of an ovarian lesion. The inclusion criteria included women who underwent surgical intervention and who had a preoperative pelvic ultrasound with laboratory investigation for CA-125 and HE4. The study validated the diagnostic performance of CA-125, RMI, HE4, and ROMA using histopathological diagnosis as the gold standard. Results The study population had a total of 213 cases of various types of benign (77%) and malignant (23%) ovarian tumors. CA-125 showed the highest sensitivity (79%) when looking at the total patient population. When divided by age, the sensitivity was 67% in premenopausal women. In postmenopausal women, CA-125 had lower sensitivity (89%) compared to RMI, HE4, and ROMA (93% each). A high specificity of 90% was found for HE4 in the total patient population, 93% in premenopausal women and 75% in postmenopausal women. CA-125 had the highest specificity (79%) in postmenopausal women. Both CA-125 and RMI were frequently elevated in benign gynecological conditions particularly in endometriosis when compared to HE4 and ROMA. We also studied modifications of the optimal cut-offs for the four parameters. Both CA-125 and RMI showed a significant increase in their specificity if the cut-off was increased to ≥ 60 U/mL for CA-125 and to ≥ 250 for RMI. For HE4, we noted an improvement in its specificity in postmenopausal women when its cut-off was increased to140 pmol/L. Conclusions HE4 and ROMA showed a very high specificity

    Within the PanGeo project (financed by the European Commission under the 7th Framework Program), the Geological Survey of Italy ( ISPRA) and the Urban Planning Department of the City of Roma developed a geodatabase and map of the geological hazards for the territory of Roma, integrating remotely sensed data (PSInSAR—Permanent Scatterer Interferometry Synthetic Aperture Radar) and in situ geological information. Numerous thematic layers, maps and inventories of hazards (e.g., landslides, sinkholes, cavities), geological and hydrogeological data added to historical and recent urbanization information were compared to the permanent scatterer (PS) data from the European Remote Sensing satellites (ERS-1/2, 1992-2000) and ENVISAT (2002-2005) descending scenes, in order to produce a ground stability layer (GSL). Based on the PS data, most of the territory appears stable (almost 70 % of PS velocities are within ±1 mm/year). About 14 % of the PSs show positive line-of-sight (LOS) velocities (measured along the LOS of the satellite) between 1 and 3 mm/year and more than 2 % exceed 3 mm/year; more than 11 % of PSs show negative LOS velocities between -1 and -3 mm/year, while about 3 % exceed -3 mm/year (with tens of the PSs showing velocities over -20 mm/year). The GSL is comprised of polygons or multi-polygons (multipart polygons grouping individual polygons under a single identifier geohazard) enclosing areas where geohazards have been pointed out by PS data and/or in situ surveys (observed instabilities), and by polygons enclosing areas potentially affected by geohazards, based on the available knowledge of the territory (potential instabilities). In Roma's GSL, 18 multi-polygons (covering ca. 600 km2) related to observed instabilities have been outlined, where ground movements could be detected through InSAR data or where landslides and sinkholes are known to have occurred. Other 13 multi-polygons (covering nearly 900 km2) concern areas where the potential occurrence

    In chronic diseases the adherence and persistence to therapeutic treatments are often lower than guidelines said. This leads to a worse therapeutic effect of the treatments and to a misuse in healthcare costs. Our study evaluates the impact of a pharmacoutilization analysis model, derived from the administrative database of the Local Health Unit Roma B. In particularly we calculate some indicators of adherence, persistence, occasional treatment and switch in patients on statins secondary prevention treatment (patients discharged from Hospital with Acute Myocardial Infarction diagnosis).

    A new method in describing the multifractal characteristics of intermittent events was introduced by Cheng and Wu [Chang T. and Wu C.C., Physical Rev, E77, 045401(R), 2008]. The procedure provides a natural connection between the rank-ordered spectrum and the idea of one-parameter scaling for monofractals. This technique has been demonstrated using results obtained from a 2D MHD simulation. It has also been successfully applied to in-situ solar wind observations [Chang T., Wu, C.C. and Podesta, J., AIP Conf Proc. 1039, 75, 2008], and the broadband electric field oscillations from the auroral zone [Tam, S.W.Y. et al., Physical Rev, E81, 036414, 2010]. We take the next step in this procedure. By using the ROMA spectra and the scaled probability distribution functions (PDFs), raw PDFs can be calculated, which can be compared directly with PDFs from observations or simulation results. In addition to 2D MHD simulation results and in-situ solar wind observation, we show clearly using the ROMA analysis the multifractal character of the 3D fluid simulation data obtained from the JHU turbulence database cluster at http://turbulence.pha.jhu.edu. In particular, we show the scaling of the non-symmetrical PDF for the parallel-velocity fluctuations of this 3D fluid data.

    Aim To assess the key characteristics related to living conditions and health in the Bayash Roma population in Baranja and Međimurje regions of Croatia and identify possible demographic and socio-economic sources of variance in self-reported health and reproductive profile. Methods The study comprised a total of 266 adult Bayash individuals from Baranja and 164 from Međimurje (aged 41.3 ± 15.1 years). Data on ethno-historical and demographic background, self-identity, life and hygiene conditions, education, employment, health insurance, and health (dietary and smoking habits, reproductive characteristics, diagnosed and undiagnosed health problems, use of medications). were obtained through interviews. Bivariate and multivariate methods were used in statistical analyses. Results The reported migratory pattern demonstrated that 88.8% of the examinees were born in the region of residence, which showed that the Bayash population was autochthonous and sedentary one. Financially, the Bayash primarily relayed on social welfare support allowance (84%) and child allowance (47%), while merely 2% were permanently and 23% occasionally employed. The proportion of the Bayash who had never attended school amounted to 33.3% (19.3% men and 60.9% women). The access to public water supply system was available to 52.5% of examinees, whereas only 1.7% had public sewage system, and 23.4% had private septic tanks. The most commonly reported health problems were frequent headaches (20.3%), stomach pain (16.3%), anxiety or insomnia (13.1%), hypertension (9.3%), and chronic obstructive pulmonary disease (COPD) (8.6%). The logistic regression identified level of education (odds ratio [OR], 0.77; 95% confidence interval [CI], 0.63-0.94) and access to health insurance (OR, 4.32; 95% CI, 1.46-12.77) as socio-economic/life-style factors playing a significant role in the occurrence of COPD. Conclusion Our results indicate poor inclusion of the Bayash in the essential social service sectors

    The potential of Salmonella population to rebound on non-washed and washed roma tomatoes and jalapeño peppers in humid storage at 4°C, 10°C, 15°C, 21°C, or 35°C for ≤12 days was investigated. The initial inoculation levels of Salmonella on peppers and tomatoes were 5.6 and 5.2 log CFU/cm(2), respectively. Air-drying of fruit surfaces resulted in contamination levels of 3.9 and 3.7 log CFU/cm(2) on inoculated peppers and tomatoes, respectively. At 21°C and 35°C, the levels of air-dried Salmonella inoculums on produce surfaces increased ≥2 log cycles, with the most rapid growth in the first 3 days. Mechanical washing on rollers (rinsing; R-treatment) or revolving brushes (rinsing and brushing; RB-treatment) with water decreased Salmonella counts by ≥2.5 log CFU/cm(2) on both peppers and tomatoes. After R- or RB-treatment, peppers stored at 21°C and 35°C permitted residual Salmonella (≤1.4 log CFU/cm(2)) to grow to 2.6-3.9 log CFU/cm(2). During storage, residual Salmonella (≤1.0 log CFU/cm(2)) on washed tomatoes increased to 3.1 log CFU/cm(2) at 35°C following R-treatment and 3.8 log CFU/cm(2) at 21°C following RB-treatment. Cold storage at 4°C and 10°C effectively prevented the proliferation of Salmonella on both washed and non-washed produce. The current study on jalapeño peppers and roma tomatoes demonstrated that Salmonella population can rebound on produce in humid storage before or after washing. The finding highlights the benefit of uninterrupted cold storage for safer produce operations. PMID:22394024

    Remote sensing data play an important role for the environmental monitoring because they allow to provide systematic information on very large areas and for a long period of time. Such information must be analyzed, validated and incorporated into proper modeling tools in order to become useful for performing risk assessment analysis. These approaches has been already applied in the field of natural hazard evaluation (i.e. for monitoring seismic, volcanic areas and landslides). However, not enough attention has been devoted to the development of validated methods for implementing quantitative analysis on civil structures. This work is dedicated to the comprehensive utilization of ERS / ENVISAT data store ESA SAR used to detect deformation trends and perform back-analysis of the investigated structures useful to calibrate the damage assessment models. After this preliminary analysis, SAR data of the new satellite mission (ie Cosmo SkyMed) were adopted to monitor the evolution of existent surface deformation processes and to detect new occurrence. The specific objective was to set up a data processing and data analysis chain tailored on a service that sustains the safe maintenance of the built-up environment, including critical construction such as public (schools, hospital, etc), strategic (dam, highways, etc) and also the cultural heritage sites. The analysis of the test area, in the southeastern sector of Roma, has provided three different levels and sub-levels of products from metropolitan area scale (territorial analysis), settlement scale (aggregated analysis) to single structure scale (damage degree associated to the structure).

    The aim of our study was to assess the value of a preoperative He4-serum-assay and ROMA-score assessment in improving the accuracy of frozen section histology in the diagnosis of borderline ovarian tumors (BOT). 113 women presenting with a unilateral ovarian mass diagnosed as serous/mucinous BOT at frozen-section-histology (FS) and/or confirmed on final pathology were recruited. Pathologists were informed of the results of preoperative clinical/instrumental assessment of all patients. For Group_A patients, additional information regarding He4, CA125, and ROMA score was available (in Group_B only CA125 was known). The comparison between Group A and Group B in terms of FS accuracy, demonstrated a consensual diagnosis in 62.8% versus 58.6% (P: n.s.), underdiagnosis in 25.6% versus 41.4% (P < 0.05), and overdiagnosis in 11.6% versus 0% (P < 0.01). Low FS diagnostic accuracy was associated with menopausal status (OR: 2.13), laparoscopic approach (OR: 2.18), mucinous histotype (OR: 2.23), low grading (OR: 1.30), and FIGO stage I (OR: 2.53). Ultrasound detection of papillae (OR: 0.29), septa (OR: 0.39), atypical vascularization (OR: 0.34), serum He4 assay (OR: 0.39), and ROMA score assessment (OR: 0.44) decreased the probability of underdiagnosis. A combined preoperative assessment through serum markers and ultrasonographic features may potentially reduce the risk of underdiagnosis of BOTs on FS while likely increasing the concomitant incidence of false-positive events.

    During a survey of human saliva by a top-down reversed-phase high-performance liquid chromatography with electrospray ionization mass spectrometry approach, two proteins eluting at 27.4 and 28.4 min, with average masses of 15 494 ± 1 and 11 142 ± 1 Da, were detected in a subject from Boston. The Δmass value (4352 Da) of the two proteins was similar to the difference in mass values between intact (150 amino acids, [a.a.]) and truncated acidic proline-rich proteins (aPRPs; 106 a.a.) suggesting an a.a. substitution in the first 106 residues resulting in a strong reduction in polarity, since under the same experimental conditions aPRPs eluted at ~22.5 min (intact) and 23.5 min (truncated forms). Manual inspection of the high-resolution high-performance liquid chromatography with electrospray ionization tandem mass spectra of the truncated isoform showed the replacement of the phosphorylated Ser-22 in PRP-3 with a Phe residue. Inspection of the tandem mass spectra of the intact isoform confirmed the substitution, which is allowed by the code transition TCT→TTT and is in agreement with the dramatic increase in elution time. The isoform was also detected in two other subjects, one from Boston (unrelated to the previous) and one from Rome. For this reason we propose to name this variant PRP-1 (PRP-3) RB (Roma-Boston) Ser22(phos)→Phe. PMID:24771659

  10. A newly discovered founder population: the Roma/Gypsies.

    The Gypsies (a misnomer, derived from an early legend about Egyptian origins) defy the conventional definition of a population: they have no nation-state, speak different languages, belong to many religions and comprise a mosaic of socially and culturally divergent groups separated by strict rules of endogamy. Referred to as "the invisible minority", the Gypsies have for centuries been ignored by Western medicine, and their genetic heritage has only recently attracted attention. Common origins from a small group of ancestors characterise the 8-10 million European Gypsies as an unusual trans-national founder population, whose exodus from India played the role of a profound demographic bottleneck. Social and economic pressures within Europe led to gradual fragmentation, generating multiple genetically differentiated subisolates. The string of population bottlenecks and founder effects have shaped a unique genetic profile, whose potential for genetic research can be met only by study designs that acknowledge cultural tradition and self-identity.

    2015-01-01

    Experiments were conducted to determine the respiration rate of tomato at 10, 20 and 30 °C using closed respiration system. Oxygen depletion and carbon dioxide accumulation in the system containing tomato was monitored. Respiration rate was found to decrease with increasing CO2 and decreasing O2 concentration. Michaelis-Menten type model based on enzyme kinetics was evaluated using experimental data generated for predicting the respiration rate. The model parameters that obtained from the respiration rate at different O2 and CO2 concentration levels were used to fit the model against the storage temperatures. The fitting was fair (R2 = 0.923 to 0.970) when the respiration rate was expressed as O2 concentation. Since inhibition constant for CO2 concentration tended towards negetive, the model was modified as a function of O2 concentration only. The modified model was fitted to the experimental data and showed good agreement (R2 = 0.998) with experimentally estimated respiration rate. PMID:26078087

    A case of a young man diagnosed with perianal nodular melanoma with a gene mutation, accompanied by regional and pulmonary metastases on initial presentation, and later on with hepatic and bone involvement, is presented. The patient underwent wide local excision but was unresponsive to dacarbazine. Targeted therapy with vemurafenib had shown clinical improvement for a 5-month duration until he showed signs of disease progression. Just after the shift of adjuvant therapy to ipilimumab, he was diagnosed with multiple cerebral metastases that eventually led to his demise 6 months after initiation of vemurafenib, having had a 12-month survival period from the time of initial melanoma diagnosis.

    In the 5th Edition we use similar denomination of blazars adopted in the previous editions. Each blazar is identified by a code, with 5BZ for all blazars, a fourth letter that specifies the type (B, G, Q or U), followed by the truncated equatorial coordinates (J2000). We introduced the edition number before the letters BZ to avoid possible confusion due to the fact that several sources changed their old names because of the new adopted classification. The codes are defined in the "Note (G1)" below. The 5th edition contains 1151 BZB sources, 92 of which are reported as candidates because we could not find their optical spectra in the literature, 1909 BZQ sources, 274 BZG sources and 227 BZU objects (1 data file).

  17. Gas hazard assessment in a densely inhabited area of Colli Albani Volcano (Cava dei Selci, Roma)

    The northwestern flank of the Colli Albani, a Quaternary volcanic complex near Rome, is characterised by high pCO 2 values and Rn activities in the groundwater and by the presence of zones with strong emission of gas from the soil. The most significant of these zones is Cava dei Selci where many houses are located very near to the gas emission site. The emitted gas consists mainly of CO 2 (up to 98 vol%) with an appreciable content of H 2S (0.8-2%). The He and C isotopic composition indicates, as for all fluids associated with the Quaternary Roman and Tuscany volcanic provinces, the presence of an upper mantle component contaminated by crustal fluids associated with subducted sediments and carbonates. An advective CO 2 flux of 37 tons/day has been estimated from the gas bubbles rising to the surface in a small drainage ditch and through a stagnant water pool, present in the rainy season in a topographically low central part of the area. A CO 2 soil flux survey with an accumulation chamber, carried out in February-March 2000 over a 12 000 m 2 surface with 242 measurement points, gave a total (mostly conductive) flux of 61 tons/day. CO 2 soil flux values vary by four orders of magnitude over a 160-m distance and by one order of magnitude over several metres. A fixed network of 114 points over 6350 m 2 has been installed in order to investigate temporal flux variations. Six surveys carried out from May 2000 to June 2001 have shown large variations of the total CO 2 soil flux (8-25 tons/day). The strong emission of CO 2 and H 2S, which are gases denser than air, produces dangerous accumulations in low areas which have caused a series of lethal accidents to animals and one to a man. The gas hazard near the houses has been assessed by continuously monitoring the CO 2 and H 2S concentration in the air at 75 cm from the ground by means of two automatic stations. Certain environmental parameters (wind direction and speed; atm P, T, humidity and rainfall) were also continuously recorded. At both stations, H 2S and CO 2 exceeded by several times the recommended concentration thresholds. The highest CO 2 and H 2S values were recorded always with wind speeds less than 1.5 m/s, mostly in the night hours. Our results indicate that there is a severe gas hazard for people living near the gas emission site of Cava dei Selci, and appropriate precautionary and prevention measures have been recommended both to residents and local authorities.

  18. [Psychoanalysis of historically foreign phenomena--exemplified by Sinti and Roma].

    PubMed

    Maciejewski, F

    1994-01-01

    The xenophobia directed at Gypsies has received little attention from the psychoanalytic vantage. The author approaches the subject by drawing upon Freud's work on the uncanny and Fenichel's on anti-semitism in order to analyse the transformation of fear of the foreign into hatred of the foreign. With reference to the difference in significance between anti-semitism and hostility towards Gypsies as operative factors in the process of western civilization, the author argues that, like anti-semitism, antagonism towards Gypsies is based in the projection of unacceptable aspects of the self onto others, but whereas the anti-semite's unconscious fantasies of Oedipal hatred are directed at the world of Jewish fathers and father-sons representing civilizational progress, unconscious hatred of Gypsies is levelled at the mother-sons symbolising the archaic world, with their adherence to the pleasure principle of matriarchy and their corresponding evasion of the constraints of patriarchy.

    Effects of Xylopia aethiopica (Dunal) A. Richard aqueous extract on the antioxidants of matured tomato fruits at red stage were investigated at 13 ± 2 °C and 80 ± 5 % relative humidity. A sample treated with sodium bicarbonate and untreated samples were included. Samples packaged in low density polyethylene (30 μm thickness) bags were analysed at intervals of 5 days. The treatments revealed statistically significant differences in ascorbic acid content of stored tomato fruits. Fruits treated with 5 % X. aethiopica on day 5 of storage had 21.0 mg/100 g which was significantly (p < 0.05) higher than 18.2 mg/100 g in untreated control samples. At 15th day of storage, ascorbic acid was 10.0 and 14.2 mg/100 g in tomato fruits treated with sodium bicarbonate and 5 % X. aethiopica respectively. The carotenoid and lycopene contents were lower in sodium bicarbonate-treated and the untreated control samples than in X. aethiopica-treated sample. The total phenolic contents were better retained in X. aethiopica-treated tomato than in control. Treatment of tomato fruits with X. aethiopica at 4 & 5 % levels significantly retained the qualities evaluated. PMID:25745258

    2014-11-15

    Purpose: This prospective, phase 2 study aimed at assessing the efficacy of accelerated fractionation radiation therapy by concomitant boosts (CBs) associated with chemoradiation therapy (CRT) of the whole pelvis, in improving the rate of pathological complete response (pCR) to treatment in patients with International Federation of Gynaecology and Obstetrics (FIGO) stage IB2-IVA locally advanced cervical cancer. Methods and Materials: Neoadjuvant CRT included conformal irradiation of the whole pelvis with a total dose of 39.6 Gy (1.8 cGy/fraction, 22 fractions), plus additional irradiation of primary tumor and parametria with 10.8 Gy administered with CBs (0.9 cGy/fraction, 12 fractions, every other day). Concomitant chemotherapy included cisplatin (20 mg/m{sup 2}, days 1-4 and 26-30 of treatment), and capecitabine (1300 mg/m{sup 2}/daily, orally) during the first 2 and the last 2 weeks of treatment. Radical hysterectomy plus pelvic with or without aortic lymphadenectomy was performed within 6 to 8 weeks from CRT. Toxicity was recorded according to Radiation Therapy Oncology Group toxicity criteria and Chassagne grading system. Based on the Simon design, 103 cases were required, and the regimen would be considered active if >45 pCR were registered (α error = 0.05; β error = 0.1). Results: pCR was documented in 51 cases (50.5%), and the regimen was considered active, according to the planned statistical assumptions. At median follow-up of 36 months (range: 7-85 months), the 3-year local failure rate was 7%, whereas the 3-year disease-free and overall survival rates were 73.0% and 86.1%, respectively. Grade 3 leukopenia and neutropenia were reported in only 1 and 2 cases, respectively. Gastrointestinal toxicity was always grade 1 or 2. Conclusions: Addition of CBs in the accelerated fractionation modality to the whole pelvis chemoradiation followed by radical surgery results in a high rate of pathologically assessed complete response to CRT and a very encouraging local control rate, with acceptable toxicity.

  3. Non-invasive deformation analysis of historical buildings through the advanced SBAS-DInSAR technique: the case of the city of Roma (Italy)

    The monitoring of urban areas and man-made structures is of key importance for the preservation of artistic, archaeological and architectural heritage. In this context, the remote sensing techniques may allow non-invasive analysis of large areas by exploiting long time series of satellite data. Among these techniques, the Synthetic Aperture Radar (SAR) Interferometry (InSAR) has already demonstrated to be an effective tool for monitoring the displacements occurring in the historical and artistic heritage located in the historical city centers. As a matter of fact, the InSAR technique allows producing spatially dense deformation maps with centimeter to millimeter accuracy, by exploiting the phase difference (interferogram) of temporally separated SAR images relevant to the same analyzed area. In order to guarantee the monitoring of urban area displacements, it is strategic to provide very long term deformation time series by also exploiting SAR data acquired by different sensors. Accordingly, ERS/ENVISAT data archive, providing acquisitions spanning the 1992-2010 time period, might allow us generating very long term deformation time-series. However, an ERS/ENVISAT data combination is limited by the two sensors slightly different carrier frequencies: 5.331 GHz for the ENVISAT sensor and 5.3 GHz for the ERS one. Therefore, because the interferometric phase is dependent on the radiation wavelength, the generation of conventional ERS/ENVISAT cross-interferograms is strongly affected by the induced decorrelation effects. In this work we show the effectiveness of the Small BAseline Subset (SBAS) (Berardino et al., 2002; Lanari et al., 2004) approach for the conservation, monitoring and risk prevention of cultural heritage. Indeed, the SBAS technique allows us to produce deformation time series at the scale of the single building by processing very long sequences of ERS-1/2 and ENVISAT (IS2 swath) SAR data, acquired with the same illumination geometry. In particular, the SBAS approach exploits only conventional ERS/ERS and ENVISAT/ENVISAT differential interferograms, in order to limit the decorrelation effects and improve the number of the detected coherent points. Accordingly, this method may play a key role for supporting the study and conservation strategies of the historical built heritage, monuments and artistic artifacts, due to its capability of generating deformation time series spanning time interval of more than 15 years. The presented results, achieved by applying the full resolution SBAS approach to an ERS/ENVISAT dataset relevant to the city of Rome, demonstrate the effectiveness of this technique to detect and analyze the temporal evolution of possible deformation phenomena affecting historical buildings within the investigated 1992-2009 time period.

    The great meridian line in the Basilica of Santa Maria degli Angeli in Rome was built in 1701/1702 with the scope to measure the Obliquity of the Earth's orbit in the following eight centuries, upon the will of pope Clement XI. During the winter solstice of 1701 the first measurements of the obliquity have been realized by Francesco Bianchini, the astronomer who designed the meridian line, upgrading the similar instrument realized by Giandomenico Cassini in San Petronio, Bononia. In this paper the accuracy of the data observed by Francesco Bianchini is discussed and compared with up-to-date ephemerides. The modern situation of this historical instrument is also presented.

    Objective To estimate the incidence of falsely elevated risk of ovarian malignancy algorithm (ROMA) in a group of women with pathologically confirmed endometrioma and to investigate the associated factors. Methods One hundred premenopausal women surgically diagnosed with ovarian endometrioma were selected. Preoperative clinical, laboratory, and surgical characteristics were compared between the elevated-risk group (ROMA-premenopausal value, ≥7.4%) and normal-risk group (ROMA-premenopausal value, <7.4%). Results Elevated ROMA was observed in 15 women (false positive rate, 15%). Excluding one woman with known chronic renal failure, we compared the characteristics of 99 women between the elevated-risk group (n=14) and the normalrisk group (n=85). None of the clinical and surgical variables distinguished the two groups. Serum level of CA 125 >82.3 U/mL and serum level of human epididymis protein 4 (HE4) >46 pmol/L could predict an elevated ROMA test with a statistical significance. When serum level of HE4 ≤46 pmol/L, none of the women showed an elevated ROMA test, regardless of serum level of CA 125; however, 55.6% of the women showed an elevated ROMA test when serum level of HE4 >46 pmol/L and CA 125 ≤82.3 U/mL and all women showed an elevated ROMA test when serum level of HE4 >46 pmol/L and CA 125 >82.3 U/mL. Conclusion The incidence of falsely elevated ROMA was 15% in the group of women with pathologically confirmed endometrioma. Interpretation of the ROMA results should be cautious when serum level of HE4 >46 pmol/L and CA 125 >82.3 U/mL in women with suspicious ovarian endometrioma. PMID:27462596

    The horse chestnut leaf-miner, Cameraria ohridella Deschka et Dimic (Lepidoptera, Gracillariidae) is a serious invasive pest of Aesculus hippocastanum in Europe. The larvae of this species feed on leaf parenchyma and can reduce the tree growth. We studied the impact of parasitoids on C. ohridella in the Czech Republic and also searched for entomopathogenic fungi associated with this pest. The results showed that the rate of parasitism varied between 5% and 15% in most cases. The most parasitized stages of C. ohridella were spinning stages and especially pupae. The most abundant parasitoid species were Minotetrastichus frontalis, Pnigalio sp. and Pediobius saulius (Hymenoptera, Eulophidae). All species are polyphagous. Using the Galleria-bait method we isolated many strains of entomopathogenic fungi. Dominant species were Paecilomyces fumosoroseus, Paecilomyces farinosus and Beauveria bassiana. The perspectives of fungal bioagents in control of C. ohridella is discussed. PMID:18399483

    Conference logo At its third edition, the Young Researcher Meeting in Rome (YRMR) proves to be a growing event in the Italian scientific panorama. The high-quality content of the abstracts submitted to the scientific committee resulted in an exciting conference, held, for the second time, at the University of Rome 'Tor Vergata' on 20 January 2012. A busy schedule covered a large variety of cutting-edge science topics: fundamental interactions, particle physics, cosmology, astrophysics, condensed matter and biomedical physics. The broad range of the subjects discussed is the distinctive feature of the YRMR, a meeting aimed at enhancing the synergy among complementary branches of science by stimulating a fruitful exchange between theoretical, experimental and computational physics.

    Objective To evaluate the use of as an aid in the identification of women who can safely undergo conservative, non-surgical management. Methods All patients referred to the Program in Women’s Oncology for surgery with a pelvic mass are evaluated at a prospective multidisciplinary tumor board (TB) where ROMA and imaging are used for management recommendations. This study evaluated women presented to TB with a pelvic mass between 2009 and 2013 who had either surgical or conservative management. Results Of the 498 patients assessed, 392 (79%) had benign disease, 22 (4%) had LMP tumors, 28 (6%) had stage I-II epithelial ovarian cancer (EOC), 36 (7%) had stage III-IV EOC and 20 (4%) had non-EOC. Using clinical assessment in conjunction with ROMA, the TB recommended observation in 188 (37.8%) women. All patients diagnosed with an invasive malignancy were recommended for surgery by the TB. In the 315 patients managed surgically, 212 were found to have benign disease and 84 women were diagnosed with an invasive malignancy. The sensitivity for the initial TB recommendations using ROMA in conjunction with clinical judgment for detecting malignancy was 100% with a specificity of 47.7% and a NPV of 100%. When including low malignant potential tumors the sensitivity was 99.1%. For stage I-IV EOC ROMA alone had a sensitivity of 95.3%. Conclusions ROMA in conjunction with clinical assessment can safely identify women for conservative management. PMID:26364809

    Caplinskas, S

    1996-01-01

    An interview is presented with Saulius Caplinskas, a virologist serving as director of Lithuania's National Center to Combat AIDS and president of the AIDS Foundation, a nongovernmental organization (NGO). AIDS is viewed principally as a health issue in Lithuania, but other institutions are gradually becoming involved. Dr. Caplinskas simultaneously heads both a governmental and nongovernmental organization because some of the activities developed with risk groups are at the margin of existing laws. The NGO allows the government to be spared direct involvement in actions that the society is not yet ready to accept. Prevention programs are lacking in Lithuania because health education and promotion were a low priority of the former Soviet Union, and discussion of homosexuality, drug addiction, and prostitution was forbidden. Social workers are nonexistent in Lithuania. Government AIDS control programs in the region have been medically oriented. Lithuania's government program has a diagnostic laboratory and a department for medical, social, and psychological support of the seropositive. An AIDS hotline and an IEC section working with the general population, mass media, and specific target groups are other activities. NGOs working in the area of AIDS receive only indirect assistance, such as use of meeting rooms. NGOs are a new development in Lithuania, and the official attitude toward them remains cautious. The first priority of the AIDS program is to increase collaboration between specialists in sexually transmitted diseases, drug use, health education, and other relevant areas. A multisectorial approach should be developed to prepare for collaboration with the NGOs. PMID:12179246

  1. Rank-ordered multifractal analysis for intermittent fluctuations with global crossover behavior

    The rank-ordered multifractal analysis (ROMA), a recently developed technique that combines the ideas of parametric rank ordering and one-parameter scaling of monofractals, has the capabilities of deciphering the multifractal characteristics of intermittent fluctuations. The method allows one to understand the multifractal properties through rank-ordered scaling or nonscaling parametric variables. The idea of the ROMA technique is applied to analyze the multifractal characteristics of the auroral zone electric-field fluctuations observed by the SIERRA sounding rocket. The observed fluctuations span across contiguous multiple regimes of scales with different multifractal characteristics. We extend the ROMA technique such that it can take into account the crossover behavior - with the possibility of collapsing probability distribution functions - over these contiguous regimes.

  2. Rank-Ordered Multifractal Analysis of Probability Distributions in Fluid Turbulence

    2015-11-01

    Rank-Ordered Multifractal Analysis (ROMA) was introduced by Chang and Wu (2008) to describe the multifractal characteristic of intermittent events. The procedure provides a natural connection between the rank-ordered spectrum and the idea of one-parameter scaling for monofractals. This technique has successfully been applied to MHD turbulence simulations and turbulence data observed in various space plasmas. In this paper, the technique is applied to the probability distributions in the inertial range of the turbulent fluid flow, as given in the vast Johns Hopkins University (JHU) turbulence database. In addition, a refined method of finding the continuous ROMA spectrum and the scaled probability distribution function (PDF) simultaneously is introduced.

    We present an analysis of the optical spectra available in the Sloan Digital Sky Survey data release nine (SDSS DR9) for the blazars listed in the ROMA-BZCAT and for the γ-ray blazar candidates selected according to their IR colors. First, we adopt a statistical approach based on Monte Carlo simulations to find the optical counterparts of the blazars listed in the ROMA-BZCAT catalog. Then, we crossmatched the SDSS spectroscopic catalog with our selected samples of blazars and γ-ray blazar candidates, searching for those with optical spectra available to classify our blazar-like sources and, whenever possible, to confirm their redshifts. Our main objectives are to determine the classification of uncertain blazars listed in the ROMA-BZCAT and to discover new gamma-ray blazars. For the ROMA-BZCAT sources, we investigated a sample of 84 blazars, confirming the classification for 20 of them and obtaining 18 new redshift estimates. For the γ-ray blazars, indicated as potential counterparts of unassociated Fermi sources or with uncertain nature, we established the blazar-like nature of 8 out of the 27 sources analyzed and confirmed 14 classifications.

  17. Ethnic and religious differentials in Bulgarian mortality, 1993-98.

    PubMed

    Kohler, Iliana V; Preston, Samuel H

    2011-03-01

    We investigated ethnic/religious mortality differentials in Bulgaria during the 1990s. The analyses employed a unique longitudinal data-set covering the entire population of Bulgaria from the census of 1992 until 1998. The mortality of Roma is very high compared to all other ethnic/religious groups. The excess applies to nearly every cause of death examined and is not entirely explained by the adverse location of Roma on social and economic variables. For young men, Muslim mortality is substantially lower than that of non-Muslims when socio-economic differences are controlled. An analysis of causes of death suggests that lower consumption of alcohol may contribute to this 'Muslim paradox'. For older Turkish women, a significant mortality disadvantage remains after controls are imposed. Suicide mortality is lower for Muslims than for Christian groups of the same ethnicity. Consistent with deteriorating economic conditions over the study period, mortality was rising, particularly for women. PMID:21294054

    Hereditary motor and sensory neuropathy type Russe (HMSNR), also called CMT4G, is an autosomal recessive inherited peripheral neuropathy (IPN) caused by a founder mutation in the HK1 gene. HMSNR affects only patients with Roma origin, similar to the better known HMSN type Lom clarified earlier. By testing IPN patients with Roma origin, we realized that HMSNR affects surprisingly many patients in the Czech Republic. HMSNR is one of the most frequent types of IPN in this country and appears to be twice more frequent than HMSNL. Pronounced lower limb atrophies and severe deformities often lead to walking inability in even young patients, but hands are usually only mildly affected even after many years of disease duration. The group of 20 patients with HMSNR presented here is the first report about the prevalence of HMSNR from central Europe. PMID:26822750

    2013-01-01

    This study examines the relationships between nationalism and integration attitudes on one hand, and anti-Roma prejudice on the other. Using Stephan and Stephan's threat theory, the study analyzes whether and to what extent these relationships are mediated by perceived economic and symbolic threats. Data were collected among 16- and 17-year-old students in Serbia and The Netherlands. A path analysis shows that perceived economic and symbolic threats mediate the relationships between nationalism and integration on one hand, and Romaphobia on the other. Moreover, the findings show that these relationships are comparable between Serbian and Dutch youth. Levels of threat and Romaphobia differ between countries. Youth in the Netherlands, who barely have contact opportunities with Roma, are characterized by higher threat and Romaphobia scores than Serbian youth, who have proportionally more contact opportunities. Explanations are discussed as well as implications for theory and prejudice reduction in diverse intercultural settings. PMID:22519428

  20. Understanding Ustasa violence.

    2010-01-01

    The Independent State of Croatia (1941-1945) was a multi-ethnic entity in which a range of political and military powers cooperated with and fought against one another. No less complicated were the ruling Ustaa movement and its relationship with Nazi Germany and Fascist Italy. The persecution of the Serbs, the Jews, and the Roma in the Independent State of Croatia was marked by differences and similarities, which were reflected the decision-making process within the Ustaa leadership. Over time, this mass violence (and Ustaa decisions) moderated due to a variety of factors: the interethnic civil war, victim reactions, local factors, and the harvest. The Italians and Germans, however, also played a role in the persecution of the Serbs, Jews, and Roma in Croatia. Simplifying narratives of the Ustaa as marginal collaborationists and state-centered concepts of genocide are inadequate when it comes to explaining Ustaa violence. PMID:20941879

    Greece is the only European Union member state that in 2008 included hepatitis A (HAV) vaccine in the routine national childhood immunization program (NCIP). Given that the resources allocated to public health have dramatically decreased since 2008 and that Greece is a low endemicity country for the disease, the benefit from universal vaccination has been questioned. The aim of this paper is to summarize the available epidemiological data of the disease for 1982-2013, and discuss the effects of universal vaccination on disease morbidity. Descriptive analysis, ARIMA modeling and time series intervention analysis were conducted using surveillance data of acute HAV. A decreasing trend of HAV notification rate over the years was identified (p<0.001). However, universal vaccination (~ 80% vaccine coverage of children) had no significant effect on the annual number of reported cases (p = 0.261) and has resulted to a progressive increase of the average age of infection in the general population. The mean age of cases before the inclusion of the vaccine to NCIP (24.1 years, SD = 1.5) was significantly lower than the mean age of cases after 2008 (31.7 years, SD = 2.1) (p<0.001). In the last decade, one third of all reported cases were Roma (a population accounting for 1.5% of the country's total population) and in 2013 three outbreaks with 16, 9 and 25 Roma cases respectively, were recorded, indicating the decreased effectiveness of the current immunization strategy in this group. Data suggest that universal vaccination may need to be re-considered. Probably a more cost effective approach would be to implement a program that will include: a) vaccination of high risk groups, b) universal vaccination of Roma children and improving conditions at Roma camps, c) education of the population and travel advice, and d) enhancement of the control measures to increase safety of shellfish and other foods.

    2008-08-01

    Consumption of raw round and Roma tomatoes has been associated with outbreaks of salmonellosis. A study was done to determine whether survival and growth of Salmonella in and on tomatoes is affected by variety of tomato, stage of ripeness, and storage temperature. The influence of acid adaptation of cells and site of inoculation on survival and growth was studied. Salmonella grew in stem scar and pulp tissues of round, Roma, and grape tomatoes stored at 12 and 21 degrees C but not in those tomatoes stored at 4 degrees C. Survival and growth was largely unaffected by variety and stage of ripeness at the time of inoculation. The pathogen did not grow on the skin of grape tomatoes stored at 4, 12, and 21 degrees C. Survival and growth of Salmonella inoculated into stem scar and pulp tissues of round and Roma tomatoes were unaffected by exposure of cells to an acidic (pH 4.75) environment before inoculation. Results emphasize the importance of preventing contamination of tomatoes with Salmonella at all stages of ripeness, regardless of variety or previous exposure of cells to an acidic environment.

    Hepatitis A vaccine was introduced in the Greek National Immunization Program in 2008. To estimate possible impact of the universal vaccination implementation, time trends of hospitalizations for hepatitis A at the Infectious Diseases Unit of a Tertiary Pediatric Hospital in Athens during 1999-2013 were analyzed. Hepatitis A hospitalizations were recorded from the discharge database and were expressed as frequencies and rate of annual departmental hospitalizations. Time series analysis (ARIMA) was used to explore trends and the impact of the vaccination. Moreover, changes in patient age, population group distribution and the duration of hospitalization were also examined. Hepatitis A hospitalizations rate significantly decreased between pre-vaccination (1999-2008) and post-vaccination (2009-2013) era from 50.5 to 20.8/1000 hospitalizations (p = 0.005). A 3-year periodicity and a trend of reduction on hepatitis A hospitalizations rates across years were noted. Roma children had significant higher rates of hepatitis A hospitalization, followed by immigrant children. Importantly, possibly due to preceding vaccine availability with considerable uptake in private market and unvaccinated group/pockets of children (Roma), overall vaccination effect was less apparent when compared to data from other countries that implemented universal vaccination. No significant change in patient age, population group distribution, or duration of hospitalization was observed. High risk groups such as Roma children should be targeted for vaccination to reduce future outbreaks. PMID:27141813

  9. Designing normative open virtual enterprises

    Garcia, Emilia; Giret, Adriana; Botti, Vicente

    2016-03-01

    There is an increasing interest on developing virtual enterprises in order to deal with the globalisation of the economy, the rapid growth of information technologies and the increase of competitiveness. In this paper we deal with the development of normative open virtual enterprises (NOVEs). They are systems with a global objective that are composed of a set of heterogeneous entities and enterprises that exchange services following a specific normative context. In order to analyse and design systems of this kind the multi-agent paradigm seems suitable because it offers a specific solution for supporting the social and contractual relationships between enterprises and for formalising their business processes. This paper presents how the Regulated Open Multi-agent systems (ROMAS) methodology, an agent-oriented software methodology, can be used to analyse and design NOVEs. ROMAS offers a complete development process that allows identifying and formalising of the structure of NOVEs, their normative context and the interactions among their members. The use of ROMAS is exemplified by means of a case study that represents an automotive supply chain.

  10. Genetic drift and the population history of the Irish travellers.

    PubMed

    Relethford, John H; Crawford, Michael H

    2013-02-01

    The Irish Travellers are an itinerant group in Ireland that has been socially isolated. Two hypotheses have been proposed concerning the genetic origin of the Travellers: (1) they are genetically related to Roma populations in Europe that share a nomadic lifestyle or (2) they are of Irish origin, and genetic differences from the rest of Ireland reflect genetic drift. These hypotheses were tested using data on 33 alleles from 12 red blood cell polymorphism loci. Comparison with other European, Roma, and Indian populations shows that the Travellers are genetically distinct from the Roma and Indian populations and most genetically similar to Ireland, in agreement with earlier genetic analyses of the Travellers. However, the Travellers are still genetically distinct from other Irish populations, which could reflect some external gene flow and/or the action of genetic drift in a small group that was descended from a small number of founders. In order to test the drift hypothesis, we analyzed genetic distances comparing the Travellers to four geographic regions in Ireland. These distances were then compared with adjusted distances that account for differential genetic drift using a method developed by Relethford (Hum Biol 68 (1996) 29-44). The unadjusted distances show the genetic distinctiveness of the Travellers. After adjustment for the expected effects of genetic drift, the Travellers are equidistant from the other Irish samples, showing their Irish origins and population history. The observed genetic differences are thus a reflection of genetic drift, and there is no evidence of any external gene flow. PMID:23180293

    Objective The purpose of this study was to develop a risk prediction score for distinguishing benign ovarian mass from malignant tumors using CA-125, human epididymis protein 4 (HE4), ultrasound findings, and menopausal status. The risk prediction score was compared to the risk of malignancy index and risk of ovarian malignancy algorithm (ROMA). Methods This was a prospective, multicenter (n=6) study with patients from six Asian countries. Patients had a pelvic mass upon imaging and were scheduled to undergo surgery. Serum CA-125 and HE4 were measured on preoperative samples, and ultrasound findings were recorded. Regression analysis was performed and a risk prediction model was developed based on the significant factors. A bootstrap technique was applied to assess the validity of the HE4 model. Results A total of 414 women with a pelvic mass were enrolled in the study, of which 328 had documented ultrasound findings. The risk prediction model that contained HE4, menopausal status, and ultrasound findings exhibited the best performance compared to models with CA-125 alone, or a combination of CA-125 and HE4. This model classified 77.2% of women with ovarian cancer as medium or high risk, and 86% of women with benign disease as very-low, low, or medium-low risk. This model exhibited better sensitivity than ROMA, but ROMA exhibited better specificity. Both models performed better than CA-125 alone. Conclusion Combining ultrasound with HE4 can improve the sensitivity for detecting ovarian cancer compared to other algorithms. PMID:25310857

    Background: Differentiation between benign and malignant ovarian neoplasms is essential to create a system for patient referrals. Objectives: The aim of the present prospective trial was to analyze the value of the risk of ovarian malignancy algorithm (ROMA) in prediction of adnexal masses malignancy in pre- and post-menopause women before operation. Materials and Methods: Preoperative serum samples were tested for CA125 and HE4 using fully automated methods (Abbott architect) and gained best cutoff. The ROMA index was analyzed in 99 patients (including 68 pre-menopause and 31 menopause) with adnexal masses referred to Imam Hossein Hospital/Tehran/Iran and had been scheduled for operation. The pathological results showed 43 cases (22 menopause) with malignant adnexal masses and 56 cases (9 menopauses) with benign adnexal masses. Demographical data, clinical symptoms and the ROMA index were separately analyzed and contrasted in benign and malignant in both menopause and pre-menopause patients. Results: The only significant difference was the older age of the malignant group vs. benign group (P = 0.001) regarding demographic findings. As concerns the clinical symptoms, presence of abdominal discomfort in pre-diagnosis period was the only significant parameter in malignant group (P = 0.001). Additionally, data analysis of patients as a total group showed that specificity (96.4%), positive predictive value (PPV) (94.1%), area under the curve (AUC) (0.907), and diagnostic accuracy (DA) (86.9%) of the ROMA were higher than HE4 (91.1%, 85.7%, 0.857 and 81.8%. respectively) and CA125 (87.9%, 67.3%, 0.828 and 75.8%, respectively) alone. Besides, negative predictive value (NPV) (86.4%) and sensitivity (86.1%) of CA125 were higher than HE4 (79.7% and 69.8%, respectively). In contrast, specificity of HE4 (91.1%) was higher than CA125 (67.9%). Data analysis of patients as two groups (pre and post menopause groups) showed the same results. Conclusions: Specificity, DA and AUC of

    YRM logo The Young Researcher Meeting (www.yrmr.it) has been a rapidly growing event for the last few years. Together with other initiatives which have emerged in several research areas, the young researcher meeting marks the awareness and the desire of PhD students, postdoctoral fellows and young researchers to play a major role in scientific progress. Devoted to the discussion and the interchange of new developments and ideas in physics, the meeting is primarily aimed at graduate students and postdoctoral researchers, who are encouraged to present their work in an informal atmosphere. One of the main purposes of the conference is to create an international network of young researchers, both experimentalists and theorists, and fruitful collaborations across the different branches of physics. Born in Rome in 2009, after three editions that strengthened it, the Young Researcher Meeting 2013 was held in Trieste. Propelled by the past success, the fourth meeting was a two-day conference on 3-4June. It was sponsored by the International School for Advanced Studies - SISSA - and the University of Padova, thus acquiring an even further international drive. In this volume, we collect some of the contributions that were presented at the conference. They cover topics in astrophysics and cosmology, particle and theoretical physics, soft and condensed matter, biophysics and medical physics.

    Dual hereditary jaundice, a combination of Dubin-Johnson and Gilbert's syndromes, is a rare clinical entity resulting from the compound defects of bilirubin conjugation and transport. We aimed to study the hereditary jaundice in 56 members from seven seemingly unrelated Roma families, to find the causal genetic defect and to estimate its origin in Roma population. On the basis of biochemical results of total and conjugated serum bilirubin and clinical observations, ABCC2 gene, TATA box and phenobarbital enhancer (PBREM) of UGT1A1 gene were analyzed by sequencing, RFLP and fragment analysis. We found a novel variant c.1013_1014delTG in the eighth exon of ABCC2 gene in 17 individuals in homozygous state. Dual defect NG_011798.1:c.[1013_1014delTG]; NG_002601.2:g.[175492_175493insTA] in homozygous state was found in four subjects. Biochemical analyses of porphyrins and coproporphyrin isomers in urine performed by HPLC showed inverted ratio of excreted coproporphyrin, with the predominance of coproporphyrin I (up to 100%), typical for patients with Dubin-Johnson syndrome. Pursuant cultural and social specifics of the population led us to suspect a founder effect; therefore, we performed a haplotype study using genotyping data from Affymetrix Genome-Wide Human SNP Array 6.0. As a result, we detected a common 86 kbp haplotype encompassing promoter and part of the ABCC2 coding region among all families, and estimated the age of the ancestral variant to 178-185 years. In this study, we found a novel deletion in ABCC2 gene, described genetic and biochemical features of dual hereditary jaundice and confirmed the existence of founder effect and common haplotype among seven Roma families.

    Upon the invasion of the host by microorganisms, innate immunity is triggered through pathogen recognition by pattern recognition receptors (PRRs). Toll-like receptors (TLRs) are the best-studied class of PRRs, and they recognize specific pathogen-associated molecular patterns (PAMPs) from various microorganisms. A large number of studies have shown that genetic variation in TLRs may influence susceptibility to infections. We assessed the genetic variation of TLR2, which encodes one of the most important TLRs, in various populations around the globe and correlated it with changes in the function of the molecule. The three best-known nonsynonymous TLR2 polymorphisms (1892C>A, 2029C>T, and 2258G>A) were assessed in different populations from the main continental masses: Romanians, Vlax-Roma, Dutch (European populations), Han Chinese (East Asia), Dogon, Fulani (Africa), and Trio Indians (America). The 2029C>T polymorphism was absent in both European and non-European populations, with the exception of the Vlax-Roma, suggesting that this polymorphism most likely arose in Indo-Aryan people after migration into South Asia. The 1892C>A polymorphism that was found exclusively in European populations, but not in Asian, African, or American volunteers, probably occurred in proto-Indo-Europeans. Interestingly, 2258G>A was present only in Europeans, including Vlax-Roma, but at a very low frequency. The differential pattern of the TLR2 polymorphisms in various populations may explain some of the differences in susceptibility to infections between these populations. PMID:22354034

    Consumption of raw produce commodities has been associated with foodborne outbreaks in the United States. In a recent Centers for Disease Control and Prevention report outlining the incidence of food-related outbreaks from 1998 to 2008, produce of all kinds were implicated in 46% of illnesses and 23% of deaths. Methods that quickly identify fecal contamination of foods, including produce, will allow prioritization of samples for testing during investigations and perhaps decrease the time required to identify specific brands or lots. We conducted a series of trials to characterize the sensitivity and specificity of scent detection dogs to accurately identify fecal contamination on raw agricultural commodities (romaine lettuce, spinach, cilantro, and roma tomatoes). Both indirect and direct methods of detection were evaluated. For the indirect detection method, two dogs were trained to detect contamination on gauze pads previously exposed to produce contaminated with feces. For the direct detection method, two dogs were trained to identify fecal contamination on fresh produce. The indirect method did not result in acceptable levels of sensitivity except for the highest levels of fecal contamination (25 g of feces). Each dog had more difficulty detecting fecal contamination on cilantro and spinach than on roma tomatoes. For the direct detection method, the dogs exhibited >75% sensitivity for detecting ≥0.25 g of feces on leafy greens (cilantro, romaine lettuce, and spinach) and roma tomatoes, with sensitivity declining as the amount of feces dropped below 0.025 g. We determined that use of a scent detection dog to screen samples for testing can increase the probability of detecting ≥0.025 g of fecal contamination by 500 to 3,000% when samples with fecal contamination are rare (≤1%).

    Abstract The aim of this study was to assess the clinical value of preoperative blood levels of HE4 as a predictor of overall survival in patients with ovarian cancer and to validate previous data of HE4 and the ROMA algorithm including HE4 and CA125 in discriminating benign and malignant ovarian tumors. Experimental design The preoperative plasma levels of HE4 and CA125 were analyzed with ELISA in 312 patients with adnexal lesions. Tumors were classified as benign (n= 206), borderline (i.e. low malignant potential tumors) (n= 25), and well (n= 14), moderately (n= 15), and poorly (n= 51) differentiated malignant. Results In univariate Cox regression analyses high levels (dichotomized at the median) of HE4, CA125, increased age (continuous variable), advanced-stage of disease 2–4, histological grade 3 and non-optimal tumor debulking at primary surgery were all significantly associated with shorter overall survival. A multivariate Cox regression model including pre-operative available covariates HE4 and CA125 both dichotomized at median in addition to age as continuous variable showed that high levels of HE4 was an independent prognostic marker for worse prognosis HR 2.02 (95% CI 1.1-3.8). In postmenopausal women the ROMA algorithm gave the highest AUC of 0.94 (95% CI, 0.90-0.97) which was higher than the separate markers HE4 AUC 0.91 (95% CI 0.86-0.95) and CA125 AUC 0.91(95% CI 0.87-0.96). Conclusions High concentration of plasma HE4 is an independent preoperative marker of poor prognosis in patients with ovarian cancer. The algorithm ROMA discriminates in postmenopausal women between malignant and benign tumors with an AUC of 0.94. PMID:22909379

    In many applications, for example cryptography and Monte Carlo simulation, there is need for random numbers. Any procedure, algorithm or device which is intended to produce such is called a random number generator (RNG). What makes a good RNG? This paper gives an overview on empirical testing of the statistical properties of the sequences produced by RNGs and special software packages designed for that purpose. We also present the results of applying a particular test suite--TestU01-- to a family of RNGs currently being developed at the Centro Interdipartimentale Vito Volterra (CIVV), Roma, Italy.

    Ozone-induced stress-ethylene emissions from the adaxial and abaxial leaf surfaces of four plant species (Glycine max (L) Merr. cv. Dare, Lycopersicon esculentum Mill cv. Roma VF, Eucalyptus globulus Labill. and Hedera helix L.) were studied to determine if the stress ethylene diffused through the stomata or cuticle. In plants not exposed to ozone, basal ethylene was detected above both the adaxial and abaxial leaf surfaces of all the plant species examined, indicating that some ethylene can diffuse across the leaf cuticle. Oxone-induced stress ethylene production in all species examined. These data indicate that ozone-induced stress ethylene primarily diffuses from the leaf via the stomata.

The main purpose of the conference was to have a unified view of different incarnations of noncommutative geometry and its applications. The seven papers collected in the present topical issue represent a good sample of the topics covered at the workshop. The conference itself was one of the climaxes of the Franco-Italian project GREFI-GENCO, which was initiated in 2007 by CNRS and INDAM to promote and enhance collaboration and exchanges between French and Italian researchers in the area of noncommutative geometry.

  5. Test-sites for earthquake prediction experiments within the Colli Albani region

    Quattrocchi, F.; Calcara, M.

    In this paper we discuss some geochemical data gathered by discrete and continuous monitoring during the 1995-1996 period, carried out for earthquake prediction test-experiments throughout the Colli Albani quiescent volcano, seat of seismicity, selecting some gas discharge sites with peri-volcanic composition. In particular we stressed the results obtained at the continuous geochemical monitoring station (GMS I, BAR site), designed by ING for geochemical surveillance of seismic events. The 12/6/1995 (M=3.6-3.8) Roma earthquake together with the 3/11/1995 (M=3.1) Tivoli earthquake was the most energetic events within the Colli Albani - Roma area, after the beginning of the continuous monitoring (1991) up today: strict correlation between these seismic events and fluid geochemical anomalies in groundwater has been discovered (temperature, Eh, 222Rn, CO 2, NH 3). Separation at depth of a vapour phase, rich in reducing-acidic gases (CO 2, H 2S, etc...), from a hyper-saline brine, within the deep geothermal reservoir is hypothesised to explain the geochemical anomalies: probably the transtensional episodes accompanying the seismic sequences caused an increasing and/or triggering of the phase-separation process and fluid migration, on the regional scale of the Western sector of the Colli Albani, beyond the seismogenic depth (2-4 Km) up to surface. We draw the state of art of GMS II monitoring prototype and the selection criteria of test-sites for earthquake prediction experiments in the Colli Albani region.

    2010-01-01

    Background Despite the launch of the national plan for measles elimination, in Italy, immunization coverage remains suboptimal and outbreaks continue to occur. Two measles outbreaks, occurred in Lazio region during 2006-2007, were investigated to identify sources of infection, transmission routes, and assess operational implications for elimination of the disease. Methods Data were obtained from several sources, the routine infectious diseases surveillance system, field epidemiological investigations, and molecular genotyping of virus by the national reference laboratory. Results Overall 449 cases were reported, sustained by two different stereotypes overlapping for few months. Serotype D4 was likely imported from Romania by a Roma/Sinti family and subsequently spread to the rest of the population. Serotype B3 was responsible for the second outbreak which started in a secondary school. Pockets of low vaccine coverage individuals (Roma/Sinti communities, high school students) facilitated the reintroduction of serotypes not endemic in Italy and facilitated the measles infection to spread. Conclusions Communities with low vaccine coverage represent a more serious public health threat than do sporadic susceptible individuals. The successful elimination of measles will require additional efforts to immunize low vaccine coverage population groups, including hard-to-reach individuals, adolescents, and young adults. An enhanced surveillance systems, which includes viral genotyping to document chains of transmission, is an essential tool for evaluating strategy to control and eliminate measles PMID:20219143

    From June 29 to July 6 2003, the German-Norwegian ROMA-SvalRak campaign (ROMA = Rocket borne Observations in the Middle Atmosphere) took place at the SvalRak rocket range, Ny-Ålesund (78.9°N, 11.9°E; Spitzbergen). The main scientific aim of this campaign was to study polar mesosphere summer echoes (PMSE) and mesospheric turbulence. During this campaign a total of three instrumented sounding rockets was launched. In addition, ground based observations with a VHF radar and a potassium lidar at Longyearbyen complemented the in situ measurements. All three sounding rockets were equipped with the CONE (COmbined sensor for Neutrals and Electrons) instrument to measure small scale structure of neutral air and electron density, and neutral temperature. The PIP (positive ion probe) instrument was used to measure small scale structure of the positive ion density. Furthermore, two cold plasma probes were flown to measure electron temperature, and a particle detector was employed to detect signatures of charged aerosols. During the first launch, an electric field experiment was also incorporated, while during the other two launches, Faraday rotation experiments yielded absolute electron number densities. During all three rocket flights a PMSE was observed by the VHF radar, whereas the potassium lidar detected a noctilucent cloud (NLC) only during the second launch. Signatures of charged particles forming the PMSE and NLC layers were recorded by the onboard particle detectors.

    OBJECTIVE: To characterize the circumstances in which poliomyelitis occurred among three children in Bulgaria during 2001 and to describe the public health response. METHODS: Bulgarian authorities investigated the three cases of polio and their contacts, conducted faecal and serological screening of children from high-risk groups, implemented enhanced surveillance for acute flaccid paralysis, and conducted supplemental immunization activities. FINDINGS: The three cases of polio studied had not been vaccinated and lived in socioeconomically deprived areas of two cities. Four Roma children from the Bourgas district had antibody titres to serotype 1 poliovirus only, and wild type 1 virus was isolated from the faeces of two asymptomatic Roma children in the Bourgas and Sofia districts. Poliovirus isolates were related genetically and represented a single evolutionary lineage; genomic sequences were less than 90% identical to poliovirus strains isolated previously in Europe, but 98.3% similar to a strain isolated in India in 2000. No cases or wild virus isolates were found after supplemental immunization activities were launched in May 2001. CONCLUSIONS: In Bulgaria, an imported poliovirus was able to circulate for two to five months among minority populations. Surveillance data strongly suggest that wild poliovirus circulation ceased shortly after supplemental immunization activities with oral poliovirus vaccine were conducted. PMID:12973639

    Objective To explore female and transvestite sex workers’ perceptions of risk in the sex work environment in Serbia. Design Qualitative interview study. Setting Street based locations for sex work in Belgrade and Pancevo, Serbia. Participants 31 female and transvestite sex workers. Results Violence, including police violence, was reported as a primary concern in relation to risk. Violence was linked to unprotected sex and the reduced capacity for avoiding sexual risk. Participants reported that coerced sex was routinely provided to the police in exchange for freedom from detainment, arrest, or fine, and was enforced by the perceived threat of violence, sometimes realised. Accounts contained multiple instances of physical and sexual assault, presented as abuses of police authority, and described policing as a form of moral punishment. This was largely through non-physical means but was also enforced through physical violence, especially towards transvestite and Roma sex workers, whose experience of police violence was reported as relentless and brutal and connected with broader social forces of discrimination in this setting, especially towards Roma. Conclusion Preventing violence towards sex workers, which can link with vulnerability to sexually transmitted infections, is a priority in Serbia. This requires monitoring perpetrators of violence, providing legal support to sex workers, and creating safer environments for sex work. PMID:18667468

    Direct numerical simulations of thermal convection are conducted for a cylindrical cell of aspect ratio .5ex1-.1em/ -.15em.25ex2 . The Prandtl number (Pr) varies from 10^0 to 10^4 and the Rayleigh numbers (Ra) are moderate (10^5 < Ra < 10^9). This study is motivated by the fact that the role of the Prandtl number in convective heat transport is not yet fully understood. The three-dimensional behaviors of the temperature and velocity fields, of the viscous and thermal dissipation fields, and of the diffusive and convective heat fluxes are explored. In the ranges of Pr and Ra considered, we find steady, periodic and chaotic regimes, and large-scale structures which are more complex than the single recirculation cell filling the whole volume. Multiple flow structures are found to be associated with a given set of conditions. The multiple solutions seem to be more probable at higher Pr numbers and could explain the scatter in some data trends.

    Pathogenic mutations of MARVELD2, encoding tricellulin, a tricelluar tight junction protein, cause autosomal recessive non-syndromic hearing loss (DFNB49) in families of Pakistan and Czech Roma origin. In fact, they are a significant cause of prelingual hearing loss in the Czech Roma, second only to GJB2 variants. Previously, we reported that mice homozygous for p.Arg497* variant of Marveld2 had a broad phenotypic spectrum, where defects were observed in the inner ear, heart, mandibular salivary gland, thyroid gland and olfactory epithelium. The current study describes the types and frequencies of MARVELD2 alleles and clinically reexamines members of DFNB49 families. We found that MARVELD2 variants are responsible for about 1.5% (95% CI: 0.8 – 2.6) of non-syndromic hearing loss in our cohort of 800 Pakistani families. The c.1331+2T>C allele is recurrent. In addition, we identified a novel large deletion in a single family, which appears to have resulted from non-allelic homologous recombination between two similar Alu short interspersed elements. Finally, we observed no other clinical manifestations co-segregating with hearing loss in DFNB49 human families, and hypothesize that the additional abnormalities in the Marveld2 mutant mouse indicates a critical non-redundant function for tricellulin in other organ systems.

    We analyze magnetic field data from Venus Express (VEX) and CLUSTER to investigate the turbulent properties of the solar wind and the Earth's and Venus' magnetosheaths. A systematic study of the PDFs (Probability Distribution Functions) of the measured magnetic fluctuations and their fourth order moments (kurtosis) reveals numerous intermittent time series. The presence of intermittency is marked by non-Gaussian PDFs with heavy wings and a scale dependent kurtosis. Higher order analyses on the scale dependence of several moment orders of the PDFs, the structure functions, along with the scaling of the kurtosis allow for a selection of scales that pertain to different scaling regimes, governed by different physics. On such sub-ranges of scales we investigate the fractal structure of fluctuations through the Rank Ordered Multifractal Analysis - ROMA (Chang and Wu, 2008). ROMA is applied to a selection of intermittent magnetic field time series in the solar wind and planetary magnetosheaths and helps to quantify the turbulence properties through the estimation of a spectrum of local Hurst exponents.

    Summary This article is based on analysis of 4 couple’s personal and public documents, in order to integrate personal choices, values and ideas with cultural representations and social attitudes. Moreover, being based on Italian sources from the nineteenth century, the study offers an historical insight on the Italian nation-building process and its political and social foundations. This study is based on archival and printed primary sources from: Gianna Maffei and Ercole Trotti Mosti (Museo Centrale del Risorgimento – Roma – MCRR); Augusto Pierantoni and Grazia Mancini (Museo Centrale del Risorgimento – Roma); Luigi Majno and Ersilia Bronzini (Archivio Unione Femminile Nazionale – Milano); Angiolo Orvieto and Laura Cantoni (Archivio Contemporaneo Bonsanti del Gabinetto Vieuesseux – Firenze – ACGV). This study reflects on love as a political and moral issue, by linking the personal sphere of subjectivity to the public dimension of the political community. An extensive understanding of the role played by the perception and the expression of sentiments can be considered as the central issue of this analysis. PMID:22037756

    Measles re-emerged in a nationwide outbreak in Bulgaria from 2009 to 2011 despite reported high vaccination coverage at national level. This followed an eight-year period since the last indigenous cases of measles were detected. The Bulgarian National Centre of Infectious and Parasitic Diseases collated measles surveillance data for 2009-2011. We analysed data for age group, sex, ethnicity, diagnosis confirmation, vaccination, hospitalisation, disease complications, and death and describe the outbreak control measures taken. The outbreak started in April 2009 following an importation of measles virus and affected 24,364 persons, predominantly Roma. Most cases (73%) were among children < 15 years old. Vaccination status was available for 52% (n = 12,630) of cases. Of children 1-14 years old, 22% (n = 1,769) were unvaccinated and 70% (n = 5,518) had received one dose of a measles-containing vaccine. Twenty-four measles-related deaths were reported. The Roma ethnic group was particularly susceptible to measles. The magnitude of the outbreak resulted primarily from the accumulation of susceptible children over time. This outbreak serves as a reminder that both high vaccination coverage and closing of immunity gaps across all sections of the population are crucial to reach the goal of measles elimination.

  15. Comparison of various multifractal approaches to analyze the intermittent magnetic fluctuations observed in the Earth's magnetospheric cusp

    Several approaches exist to compute the multifractal characteristics of an intermittent set of fluctuations. First, the classical method based on the computation of the partition function uses the full set of fluctuations . Since it is dominated by the more numerous fluctuations of small amplitudes, this method can mask the fractal characteristics of minor fluctuations of much larger amplitude. To solve this issue, a new method was developed by Chang & Wu (2008) : the Rank-Ordered Multifractal Analysis (ROMA) The ROMA method offers a natural connection between the one-parameter monofractal scaling idea and the multifractal phenomenon of intermittency. The key-element in ROMA is to find s(Y), the spectrum of the scaling exponents, and Ps(Y), the scaled Probability Distribution Function (PDFs), from the raw PDFs of the variable X at various scales tau , P(X,tau), with the following scaling: P(X,tau) tau ^s(Y)=Ps(Y) with Y= X/tau ^s(Y) The first (direct) method is to use range-limited structure functions in a sufficiently small range of the scaled variable Y and search for the value of monofroctal exponent s(Y). A drawback of this approach is that the range of Y must be large enough to ensure that the statistics is meaningful. As a consequence, some cross-over behavior between fluctuations with different monofractal exponents can lead to an ambiguity with several solutions s(Y) for some ranges of Y. Also the multifractal spectrum produced is step-wise discontinuous. To overcome these difficulties, Wu & Chang (2011) have suggested a refined method where a value of the parameter s is assumed and the corresponding value of Y ensuring a collapse of the raw PDFs is searched for. The advantage of this latter approach is that s(Y) and Ps(Y) can be obtained for single values of Y. The two ROMA methods and the partition function method are used on a set of intermittent magnetic field fluctuations observed by the Cluster spacecraft in the Earth's magnetospheric cusp. Results

    Università degli Studi di Roma "La Sapienza", Scuola di Ingegneria Aerospaziale, Via Eudossiana 16, 00184 At Università di Roma "La Sapienza" a nanosatellite bus is under development, with one liter target volume and one kilogram target weight. This nanosatellite, called URSA MAIOR (Università di Roma "la SApienza" Micro Autonomous Imager in ORbit) has a micro camera on board to take pictures of the Earth. The nanosatellite is three axis stabilized, using a micro momentum wheel, with magnetic coils for active nutation damping and pointing control. An experimental micropropulsion system is present on-board, together with the magnetic attitude control system. The design, construction and testing of the satellite is carried on by academic personnel and by students, which are directly involved in the whole process, as it is in the spirit of in the microsatellite program at Università di Roma "La Sapienza". Few technological payloads are present on-board: an Earth imaging experiment, using a few grams commercial-off-the-shelf microcamera; commercial Li-Ion batteries are the only energy storage device; a microwheel developed at our University laboratories provides for attitude stabilization. In addition, a micropropulsion experiment is planned on-board. The Austrian Company Mechatronic, and INFM, an Italian Research Institute at Trieste are developing a microthruster for nanosatelite applications. In the frame of a cooperation established between these two Institutions and Università di Roma "La Sapienza", this newly developed hardware will be tested in orbit. The thruster is made basically of an integrated microvalve, built on a silicon chip, and a micronozzle, etched on the same silicon chip, to get supersonic expansion of the gas flow. The nominal thrust of the system is about 100microN. The throat section is about 100 micron diameter. The first phase in the construction of the microthruster has been the construction of the micronozzle on a silicon chip. A

    2012-03-19

    The historical record tells us stories of migrations, population expansions and colonization events in the last few thousand years, but what was their demographic impact? Genetics can throw light on this issue, and has mostly done so through the maternally inherited mitochondrial DNA (mtDNA) and the male-specific Y chromosome. However, there are a number of problems, including marker ascertainment bias, possible influences of natural selection, and the obscuring layers of the palimpsest of historical and prehistorical events. Y-chromosomal lineages are particularly affected by genetic drift, which can be accentuated by recent social selection. A diversity of approaches to expansions in Europe is yielding insights into the histories of Phoenicians, Roma, Anglo-Saxons and Vikings, and new methods for producing and analysing genome-wide data hold much promise. The field would benefit from more consensus on appropriate methods, and better communication between geneticists and experts in other disciplines, such as history, archaeology and linguistics.

    Hereditary motor and sensory neuropathy type Lom, initially identified in Roma (Gypsy) families from Bulgaria, has been mapped to 8q24. Further refined mapping of the region has been undertaken on DNA from patients diagnosed across Europe. The refined map consists of 25 microsatellite markers over approximately 3 cM. In this collaborative study we have identified a number of historical recombinations resulting from the spread of the hereditary motor and sensory neuropathy type Lom gene through Europe with the migration and isolation of Gypsy groups. Recombination mapping and the minimal region of homozygosity reduced the original 3 cM hereditary motor and sensory neuropathy type Lom region to a critical interval of about 200 kb. PMID:11053686

    The SPARC project has entered its installation phase at the Frascati National Laboratories of INFN: its main goal, the promotion of an R&D activity oriented to the development of a high brightness photoinjector to drive SASE-FEL experiments, is being vigorously pursued by a collaboration among ENEA-INFN-CNR-Universita di Roma Tor Vergata-INFM-ST. In this paper we will report on the installation and test of some major components, like Ti:Sa laser system, RF gun and RF power system. Advancements in the control and beam diagnostics systems will also be reported, in particular on the emittance-meter device for beam emittance measurements in the drift space downstream the RF gun. Recent results on laser pulse shaping show the feasibility of producing 10 ps flat-top laser pulses in the UV with rise time below 1 ps. First FEL experiments have been proposed, using SASE, seeding and non-linear resonant harmonics.

    This paper deals with the creation of appropriate conditions aimed at developing social services for reuse and recycling of waste electrical and electronic equipment (WEEE), by the inclusion of handicapped and Roma people in the workforce. Application areas for the project are the Hellenic (Greek) regions of Thessaly and North Aegean, where these groups suffer from professional and social exclusion. The efforts to reduce unemployment in the two aforementioned groups, together with the efforts to implement related Greek and European legislation for sustainable WEEE management, are examined here. Furthermore, networking and cooperation at local, regional and central levels between small enterprises, entrepreneurships and local authorities are examined, so that these social enterprises and their corresponding investments may support the development of the Greek alternative WEEE recycling system.

    Many kilometers of roads have adjacent rock slopes that are prone to rockfall. The analysis of risks associated with these types of instabilities is a complex operation requiring the precise assessment of hazard, the vulnerability and therefore the risk of vehicles on roads along the foothills. Engineering design of protection devices should aim to minimize risk while taking advantage of the most advanced technologies. Decision makers should be equipped with the technical tools permitting them to choose the best solution within the context of local maximum acceptable risk levels. The fulfilment of safety requirements for mountainside routes involves in many cases the implementation of protective measures and devices to control and manage rockfall and it is of key importance the evaluation of the positive effects of such measures in terms of risk reduction. A risk analysis management procedure for roads subject to rockfall phenomena using a specifically developed method named: Rockfall risk Management (RO.MA.) is presented and discussed. The method is based on statistic tools, using as input the data coming both from in situ survey and from historical data. It is important to highline that historical database are not often available and usually there is a lack of useful information due to a not complete setting of parameters. The analysis based only on historical data can be difficult to be developed. For this purpose a specific database collection system has been developed to provide geotechnical and geomechanical description of the studied rockside. This parameters and the data collected from historical database, define the input parameters of the Ro.Ma method. Moreover to allow the quantification of the harm, the data coming from the monitoring of the road by the road manager are required. The value of harm is proportional to the number of persons on the road (i.e. people in a vehicle) and the following traffic characteristics: type of vehicles (i.e. bicycles

    We examined multistate outbreaks attributed to raw tomatoes in the United States from 1990 to 2010. We summarized the demographic and epidemiological characteristics of 15 outbreaks resulting in 1959 illnesses, 384 hospitalizations, and three deaths. Most (80%) outbreaks were reported during 2000-2010; 73% occurred May-September. Outbreaks commonly affected adult (median age 34 years) women (median 58% of outbreak cases). All outbreaks were caused by Salmonella [serotypes Newport (n = 6 outbreaks), Braenderup (n = 2), Baildon, Enteritidis, Javiana, Montevideo, Thompson, Typhimurium (n = 1 each); multiple serotypes (n = 1)]. Red, round (69% of outbreaks), Roma (23%), and grape (8%) tomatoes were implicated. Most (93%) outbreaks were associated with tomatoes served predominantly in restaurants. However, traceback investigations suggested that contamination occurred on farms, at packinghouses, or at fresh-cut processing facilities. Government agencies, academia, trade associations, and the fresh tomato industry should consider further efforts to identify interventions to reduce contamination of tomatoes during production and processing.

    In this work we present an extension of the ROMA map-making code for data analysis of Cosmic Microwave Background polarization, with particular attention given to the inflationary polarization B-modes. The new algorithm takes into account a possible cross- correlated noise component among the different detectors of a CMB experiment. We tested the code on the observational data of the BOOMERanG (2003) experiment and we show that we are provided with a better estimate of the power spectra, in particular the error bars of the BB spectrum are smaller up to 20% for low multipoles. We point out the general validity of the new method. A possible future application is the LSPE balloon experiment, devoted to the observation of polarization at large angular scales.

    This paper is the first report about the development of a methodology for the virtual Anastylosis of elements belonging to an archaeological site, based on the 3d modeling of fragments. This research is the result of the cooperation between Università Roma Tre, Dipartimento di Architettura and Sovrintendenza Capitolina ai Beni Culturali; several 3D survey, modeling, information systems and archaeology experts were involved. The purpose of the research was to study the complex and stratified site of the Arch of Titus at the Circus Maximus aiming, first of all, at completing the existing traditional graphic documentation using cataloguing and survey innovative methodologies, and, secondly, at supporting new proposals for the reconstruction and Anastylosis of the Arch itself. This tested methodology whose fundamental element is the three-dimensional textured model of each fragment, can also be used in other sites and contexts.

    2015-09-01

    Studying pulsars from ground-based telescopes needs data analysis to be performed according to specific requirements. Because of the periodic behavior of these objects such requirements are expressed in terms of timing. In fact, several factors must be taken into account to correctly extract the period (frequency) and then light curves of pulsars. Until now, analysis software packages have been mainly developed for satellite data and are not completely suitable for optical observations from the ground. A software package called GUIDA has been developed to analyze optical photometric data recorded by the SiFAP instrument, completely conceived and realized at the Physics Department of La Sapienza-Università di Roma. This software package is capable of analyzing data relative to ground observations, including timing corrections, and of deriving corrected pulsar light curves.

This article was reporting the first discovery of a planet orbiting a star beyond our Sun, namely the solar-type star 51 Pegasi. Nearly four centuries after Giordano Bruno was burnt in public in Roma partly for having intuitively claimed the plurality of worlds, we were entering the extraordinary epoch in which one of the oldest inquiries of mankind-are we alone in the Universe?-can be tackled with the scientific method, leaving aside centuries of endless speculations. To date (July 2010), almost 500 extrasolar planets are known. We shall briefly review the main detection methods, together with the big surprises which arose during these last exciting fifteen years, without being exhaustive.

    The Bayash are a branch of Romanian speaking Roma living dispersedly in Central, Eastern, and Southeastern Europe. To better understand the molecular architecture and origin of the Croatian Bayash paternal gene pool, 151 Bayash Y chromosomes were analyzed for 16 SNPs and 17 STRs and compared with European Romani and non-Romani majority populations from Europe, Turkey, and South Asia. Two main layers of Bayash paternal gene pool were identified: ancestral (Indian) and recent (European). The reduced diversity and expansion signals of H1a patrilineages imply descent from closely related paternal ancestors who could have settled in the Indian subcontinent, possibly as early as between the eighth and tenth centuries AD. The recent layer of the Bayash paternal pool is dominated by a specific subset of E1b1b1a lineages that are not found in the Balkan majority populations. At least two private mutational events occurred in the Bayash during their migrations from the southern Balkans toward Romania. Additional admixture, evident in the low frequencies of typical European haplogroups, J2, R1a, I1, R1b1b2, G, and I2a, took place primarily during the early Bayash settlement in the Balkans and the Romani bondage in Romania. Our results indicate two phenomena in the Bayash and analyzed Roma: a significant preservation of ancestral H1a haplotypes as a result of considerable, but variable level of endogamy and isolation and differential distribution of less frequent, but typical European lineages due to different patterns of the early demographic history in Europe marked by differential admixture and genetic drift.

    The MONOLITH (Massive Observatory for Neutrino Oscillation or LImits on THeir existence) project is a proposal (N.Y. Agafonova et al., 2000) for an experiment to be installed in the Gran Sasso underground laboratory to study atmospheric neutrino oscillations with a massive magnetized iron tracking calorimeter . The main purpose is to confirm the existence of atmospheric neutrino oscillations through the explicit observation of the first oscillation minimum in νµ disappearance. The MONOLITH detector has been designed in order to discriminate among different oscillation modes and to accurately measure the oscillation parameters in a range that completely covers the Super-Kamiokande allowed region. Other measurements include studies of matter effects, the NC up down ratio, the ¯ν/ν ratio, the study of cosmic ray muons in the multi-TeV energy region, and auxiliary measurements from the CERN to Gran Sasso neutrino beam.

The foreseen launch of new space platforms as the Sentinel satellites, providing good monitoring frequencies and free worldwide access to data is expected to increase the number of scientific and commercial activities exploiting EO data. In the sector of natural hazards the EO data have already demonstrated to be indispensable for the generation of information products for the prevention, and emergency management phases. In particular, the Italian Space Agency has promoted and funded, together with INGV, the development of dedicated infrastructures for the generation of advanced information products supporting different phases of the seismic and volcanic risk management cycles. These products were based mainly on SAR data from the COSMO-SkyMed 4-satellite constellation, and on optical data from commercial and scientific platforms, integrated with data from ground monitoring networks. During the last few years, such infrastructures have been tested under operational conditions and the products distributed to the Italian Civil Protection authority for validation and assessment. Here, with reference to the earthquake emergency management, we will present the infrastructure, the rapid mapping information products and some examples of activities during the latest seismic crises.

The participants were also able to get involved with sample testing. Tutorial lectures were delivered at the school, addressing general and basic questions about nanotechnology, such as what they are, how does one go about them, what purposes can they serve. In tutorial sessions the nature of nanotechnology, the instruments of current use in its characterizations and the possible applicative uses were described at an introductory level. The first day was devoted to three sessions: Aerospace, defense, biomedicine. Electronics and mechanical properties. Materials and characterizations. The first session was opened by a lecture by J Kenny, who talked about the use of carbon nanotubes for polymer matrix nanocomposites. He reported how plasma functionalized single-walled carbon nanotubes (F-SWNTs) reacted with a primary aliphatic amine can be used for preparing an integrated nanotube composite

    One of the main limitations in the access to space for developing countries is the economical effort typically required by space missions. Secondly, space activity is a field of very high technology, requiring technical skills, education and practice, at a level which is seldom reached by developing countries. Interventions aimed to facilitate access to space for developing countries should be focussed primarily on the missions allowing access to space at reasonable cost. Moreover, perhaps more importantly, they should emphasize conducting the mission design, construction, ground testing and operation in orbit as an open activity, accessible to developing countries personnel, in order to set up an education process, which is not just selling a product ready satellite. Universities could have a very important role in this activity. Many Universities around the world have designed, built and launched small satellites. Università di Roma "La Sapienza" set up a program for the construction of small satellites in an academic environment, involving directly the students in the design, construction, ground testing and operation in orbit. The first satellite built in the framework of this program, UNISAT, was successfully launched in September 2000. The second, UNISAT-2, initially scheduled for launch in 2001, has been delayed by the launch provider to late 2002. These two satellites, based on a modular design, emphasizing ease of construction and assembly, weight roughly 10 kg. The realization of these satellites was made possible within the regular financing given to university research programs, keeping down cost by the use of commercial off the shelf components instead of space rated ones. The microsatellite experience at Università di Roma "La Sapienza", is going further with the development of a new nanosatellite bus, URSA MAIOR (Università di Roma "la SApienza" Micro Autonomous Imager in ORbit), aiming at cutting down cost and possibly improving performance.

    Introduction The prevalence of cognitive impairment may be increased in adults with end-stage kidney disease compared with the general population. However, the specific patterns of cognitive impairment and association of cognitive dysfunction with activities of daily living and clinical outcomes (including withdrawal from treatment) among haemodialysis patients remain incompletely understood. The COGNITIVE impairment in adults with end-stage kidney disease treated with HemoDialysis (COGNITIVE-HD) study aims to characterise the age-adjusted and education-adjusted patterns of cognitive impairment (using comprehensive testing for executive function, perceptual-motor function, language, learning and memory, and complex attention) in patients on haemodialysis and association with clinical outcomes. Methods and analysis A prospective, longitudinal, cohort study of 750 adults with end-stage kidney disease treated with long-term haemodialysis has been recruited within haemodialysis centres in Italy (July 2013 to April 2014). Testing for neurocognitive function was carried out by a trained psychologist at baseline to assess cognitive functioning. The primary study factor is cognitive impairment and secondary study factors will be specific domains of cognitive function. The primary outcome will be total mortality. Secondary outcomes will be cause-specific mortality, major cardiovascular events, fatal and non-fatal myocardial infarction and stroke, institutionalisation, and withdrawal from treatment at 12 months. Ethics and dissemination This protocol was approved before study conduct by the following responsible ethics committees: Catania (approval reference 186/BE; 26/09/2013), Agrigento (protocol numbers 61–62; 28/6/2013), USL Roma C (CE 39217; 24/6/2013), USL Roma F (protocol number 0041708; 23/7/2013), USL Latina (protocol number 20090/A001/2011; 12/7/2013), Trapani (protocol number 3413; 16/7/2013) and Brindisi (protocol number 40259; 6/6/2013).

    From June 29 to July 7 2003, the German-Norwegian ROMA/SVALRAK campaign (ROMA = Rocket borne Observations in the Middle Atmosphere) took place at the SVALRAK rocket range, Ny-Ålesund (79°N, 11°E; Spitsbergen). The main scientific aim of this campaign was to study polar mesosphere summer echoes (PMSE) and mesospheric turbulence. During this campaign a total of three instrumented sounding rockets was launched. In addition, ground based observations with a VHF radar and a potassium lidar at Longyearbyen complemented the in situ measurements. All three sounding rockets were equipped with the CONE (= COmbined sensor for Neutrals and Electrons) instrument to measure small scale structure of neutral air and electron density, and neutral temperature. The PIP (= Positive Ion Probe) instrument was used to measure small scale structure of the positive ion density. Furthermore, two cold plasma probes (CPP) were used to measure electron temperature, and a particle detector was employed to detect signatures of charged aerosols. During the first launch, an electric field experiment was also incorporated, while during the other two launches, Faraday rotation experiments yielded absolute electron number densities. During all three rocket flights a PMSE was observed by the VHF radar, whereas the potassium lidar detected a noctilucent cloud (NLC) only during the second launch. Signatures of the charged particles forming the PMSE and NLC layers were recorded by the onboard particle detectors. During the first launch neutral air density fluctuations indicating turbulence in the altitude region from ˜ 74 km up to ˜ 90 km were detected by the CONE instrument. In addition, CONE recorded very strong and high frequency neutral density fluctuations between altitudes of 90 km up to the apogee of ˜ 106 km. Clearly, these fluctuations are of non-turbulent origin. Strong positive ion and electron density fluctuations were also detected in the same altitude region (˜ 90 -106 km). These

    Students in science, particularly in physics, face a fascinating and challenging future. Scientists have proposed very interesting theories, which describe the microscopic and macroscopic world fairly well, trying to match the quantum regime with cosmological scales. Between the extremes of this scenario, biological phenomena in all their complexity take place, challenging the laws we observe in the atomic and sub-atomic world. More and more accurate and complex experiments have been devised and these are now going to test the paradigms of physics. Notable experiments include: the Large Hadronic Collider (LHC), which is going to shed light on the physics of the Standard Model of Particles and its extensions; the Planck-Herschel satellites, which target a very precise measurement of the properties of our Universe; and the Free Electron Lasers facilities, which produce high-brilliance, ultrafast X-ray pulses, allowing the investigation of the fundamental processes of solid state physics, chemistry, and biology. These projects are the result of huge collaborations spread across the world, involving scientists belonging to different and complementary research fields: physicists, chemists, biologists and others, keen to make the best of these extraordinary laboratories. Even though each branch of science is experiencing a process of growing specialization, it is very important to keep an eye on the global picture, remaining aware of the deep interconnections between inherent fields. This is even more crucial for students who are beginning their research careers. These considerations motivated PhD students and young post-docs connected to the Roman scientific research area to organize a conference, to establish the background and the network for interactions and collaborations. This resulted in the 1st and 2nd Young Researchers Meetings in Rome (http://ryrm.roma2.infn.it), one day conferences aimed primarily at graduate students and post-docs, working in physics in Italy

    Two varieties of tomato fruits commonly available in Nigerian markets are the Roma VF and Ibadan local varieties of tomato fruits. The Roma VF fruits are oval in shape. It is a common type of cultivar in the Northern region of Nigeria and it is not susceptible to cracking. The Ibadan local variety of tomato fruits is a local variety commonly found on farmers fields in South-western region of Nigeria. They are highly susceptible to cracking. The Ibadan local variety was employed for this research. There are lots of benefits derived from the consumption of tomato fruits. The fruits can be made into tomato juice clarified with pectinases. Polygalacturonase is one of the pectinases used commercially in the clarification of fruit juice from different fruits. This study examined the production of polygalacturonase during the deterioration of tomato fruits by Aspergillus niger and the role of the purified polygalacturonase in the clarification of tomato juice. Tomato fruits of the Ibadan local variety were inoculated with mycelia discs containing spores of a 96-h-old culture of Aspergillus niger served as the inoculum. The organism from the stock culture was subcultured onto potato dextrose agar plates. The extraction of polygalacturonase after 10 days of incubation at 27 degrees C was carried out by homogenizing the fruits with liquid extractant using the MSE homogenizer after the deteriorated fruits had been chilled for 30 min inside a freezer. Control fruits were similarly treated except that sterile potato dextrose agar served as the inoculum. The effect of different temperature of incubation and different volume of enzyme on the tomato juice from the tomato fruits was investigated. Extracts from the inoculated fruits exhibited appreciable polygalacturonase activity. The juice with polygalacturonase was visually clearer and more voluminous than the juice treated with water for all parameters studied. The highest volume of juice was obtained after an incubation period

    The Quaternary Roman Volcanic Province extends for over 200 km along the Tyrrhenian margin of the Italian peninsula and is composed of several caldera complexes with significant associated geothermal potential. In spite of the massive programs of explorations conducted by the then state-owned ENEL and AGIP companies between the 1970s and 1990s, and the identification of several high enthalpy fields, this resource remains so far unexploited, although it occurs right below the densely populated metropolitan area of Roma capital city. The main reason for this failure is that deep geothermal reservoirs are associated with fractured rocks, the secondary permeability of which has been difficult to predict making the identification of the most productive volumes of the reservoirs and the localisation of productive wells uncertain. As a consequence, almost half of the many exploration deep bore-holes drilled in the area reached a dry target. This work reviews available data and re-assesses the geothermal potential of caldera-related systems in Central Italy, by analysing in detail the case of the Colli Albani caldera system, the closest to Roma capital city. A GIS based approach identifies the most promising reservoir volumes for geothermal exploitation and uses an improved volume method approach for the evaluation of geothermal potential. The approach is based on a three dimensional matrix of georeferenced spatial data; the A axis accounts for the modelling of the depth of the top of the reservoirs based on geophysical and direct data; the B axis accounts for the thermal modelling of the crust (i.e. T with depth) based on measured thermal gradients. Both A and B data are necessary but not sufficient to identify rock volumes actually permeated by geothermal fluids in fractured reservoirs. We discuss the implementation of a C axis that evaluates all surface data indicating permeability in the reservoir and actual geothermal fluid circulation. We consider datasets on: i

    Throughout the last decades, development of low-temperat- ure detectors focused mainly on the design of high-sensitivity, single-pixel devices. This includes such devices as semiconductor-based photodetectors and bolometers, Magnetic Metallic Calorimeters (MMC), Superconducting Tunnel Junctions (STJ), and Transition Edge Sensors (TES). However, these devices have had limited success in achieving the simultaneous large-scale array sizes and large-bandwidth operation necessary for high-speed, high-resolution detection. To overcome this performance limitation, it is advisable to focus on low-temperature detectors which are intrinsically adapted to giant-array multiplexing and ultra-fast readout. To adopt large scale frequency-domain multiplexing for low-temperature detectors, it is necessary to find detectors which"broadcast" at microwave frequencies. Superconducting microwave resonators naturally lend themselves to this task. One recent demonstration is an implementation known as Kinetic Inductance Detectors (KIDs). This detection mechanism can be adopted for low-energy EM radiation (radio, mm, THz) in continuous mode, or in pulsed mode for higher energy radiation and particles. We present an ongoing development for a KIDs instrument dedicated to millimetric ground-based observations at the 30m IRAM telescope at Pico Veleta. The Neel IRAM KIDs Array (NIKA) project is coordinated in Grenoble and involves groups in Holland (SRON), UK (Cardiff) and Italy (Roma).

    Recombination effects can affect the detectors used for the dosimetry of radiotherapy fields. They are important when using ionization chambers, especially in liquid-filled ionization chambers, and should be corrected for. The introduction of flattening-filter-free accelerators increases the typical dose-per-pulse used in radiotherapy beams, which leads to more important recombination effects. Diamond detectors provide a good solution for the dosimetry and quality assurance of small radiotherapy fields, due to their low energy dependence and small volume. The group of Università di Roma Tor Vergata has developed a synthetic diamond detector, which is commercialized by PTW as microDiamond detector type 60019. In this work we present an experimental characterization of the collection efficiency of the microDiamond detector, focusing on high dose-per-pulse FFF beams. The collection efficiency decreases with dose-per-pulse, down to 0.978 at 2.2 mGy/pulse, following a Fowler-Attix-like curve. On the other hand, we have found no significant dependence of the collection efficiency on the pulse repetition frequency (or pulse period).

    SUMMARY In 2008, nationwide investigations of a Salmonella serotype Saintpaul outbreak led first to consumer warnings for Roma and red round tomatoes, then later for jalapeño and serrano peppers. In New Mexico, where there were a large number of cases but no restaurant-based clusters, the NM Department of Health and the Indian Health Service participated with CDC in individual-level and household-level case-control studies of infections in New Mexico and the Navajo Nation. No food item was associated in the individual-level study. In the household-level study, households with an ill member were more likely to have had jalapeño peppers present during the exposure period and to have reported ever having serrano peppers in the household. This report illustrates the complexity of this investigation, the limitations of traditional individual-level case-control studies when vehicles of infection are ingredients or commonly eaten with other foods, and the added value of a household-level study.

    An individual's neurodevelopmental and cognitive sequelae to negative early experiences may, in part, be explained by genetic susceptibility. We examined whether extreme differences in the early caregiving environment, defined as exposure to severe psychosocial deprivation associated with institutional care compared to normative rearing, interacted with a biologically informed genoset comprising BDNF (rs6265), COMT (rs4680), and SIRT1 (rs3758391) to predict distinct outcomes of neurodevelopment at age 8 (N = 193, 97 males and 96 females). Ethnicity was categorized as Romanian (71%), Roma (21%), unknown (7%), or other (1%). We identified a significant interaction between early caregiving environment (i.e., institutionalized versus never institutionalized children) and the a priori defined genoset for full-scale IQ, two spatial working memory tasks, and prefrontal cortex gray matter volume. Model validation was performed using a bootstrap resampling procedure. Although we hypothesized that the effect of this genoset would operate in a manner consistent with differential susceptibility, our results demonstrate a complex interaction where vantage susceptibility, diathesis stress, and differential susceptibility are implicated.

    Costruito per chiara volontà del papa 70 anni dopo il caso Galileo, lo Gnomone Clementino è un grande telescopio solare che non fa uso di lenti a 92 anni dall’invenzione del cannocchiale. Queste due caratteristiche basterebbero da sole a giustificare l’interesse verso questo strumento. L’astronomia meridiana è alla base dell’astrometria e dell’astrofisica moderna. Lo Gnomone Clementino sta oggi all’astronomia, come il veliero “Amerigo Vespucci” sta alla Marina Italiana. E’ possibile svolgere ogni genere di osservazione e studio su questo strumento, e dal 2002 vi tengo lezioni teorico-pratiche del corso di Storia dell’Astronomia e La Terra nel Sistema Solare della Sapienza, Università di Roma, Facoltà di Lettere e Filosofia. Questo testo aggiunge alcuni tasselli alla ricerca storica sulla meridiana, appoggiandosi, com’è naturale, sulle spalle di giganti che mi hanno preceduto in questi studi. In particolare la misura dell’azimut della meridiana, ed il suo inquadramento tra gli strumenti simili ed alcuni studi di astrometria sui dati del 1701-1703 di Bianchini, che sono apparsi fin’ora soltanto su riviste specializzate ed in Inglese vengono qui proposti in Italiano e semplificati, per valorizzare sempre più questa straordinaria opera d’arte e di scienza.

    The Soft X-ray Imager (SXI), sensitive in the 0.1-10 keV band, is a X-ray telescope foreseen on board of the EXIST mission. SXI is proposed as a contribution of ASI, the Italian space agency, and it is fully developed by Italian institutes. The current optical design is based on 26 mirror-shells and provides an effective area comparable to one XMM-Newton mirror module up to 3 keV and somewhat lower from 3 to 10 keV. The realization of these shells is based on the well-proven Nichel replication-process technology. We present the optical design of the SXI mirror module and describe its characteristics in term of effective area and imaging capability, summarizing also the characteristics of the full SXI telescope. Acknowledgement: the study of the SXI telescope in Italy is carried out at the INAF-OABr, INAF-IASF_Milano and INAF-IASF_Roma Institutes and is financed by the Italian Space Agency under the ASI contract I/088/06/0.

    During the past several summers the Soprintendenza Archeologica di Roma and the American Academy in Rome have carried out collaborative excavations on the late Roman complex located on the northeastern slope of the Palatine Hill. The late Roman complex is situated on the lower slopes of the area commonly known as Vigna Barberini, after its 17th century owners. Because this area, as well as most of the east slope of the Palatine, has never been systematically explored, it remains from an archaeological point of view essentially unknown. The overall aim of the excavations is to investigate layout, function, and occupational history of a mid-to-late imperial building complex located just southwest of the Arch of Constatine. Part of this international project is the chemical characterization of Roman fineware pottery from archaeological excavations on the site of the imperial palaces. Excavation has yielded more than 8 t of Late Roman and Early Medieval pottery (circa 3rd to 10th centuries A.D.). Many classes of pottery have already been classified by their provenance based on distribution patterns, but others require chemical characterization to separate similar clays. To that end routine neutron activation analysis (NAA) methods have been used to analyze {approximately}200 pieces of pottery.

    Summer vacations in the Dolomites were a tradition among the professors of the Faculty of Mathematical and Physical Sciences at the University of Roma since the end of the XIX century. Beyond the academic walls, people like Tullio Levi-Civita, Federigo Enriques and Ugo Amaldi sr., together with their families, were meeting friends and colleagues in Cortina, San Vito, Dobbiaco, Vigo di Fassa and Selva, enjoying trekking together with scientific discussions. The tradition was transmitted to the next generations, in particular in the first half of the XX century, and the group of via Panisperna was directly connected: Edoardo Amaldi, the son of the mathematician Ugo sr., rented at least during two summers, in 1925 and in 1949, and in the winter of 1960, a house in San Vito di Cadore, and almost every year in the Dolomites; Enrico Fermi was a frequent guest. Many important steps in modern physics, in particular the development of the Fermi-Dirac statistics and the Fermi theory of beta decay, are related to scientific discussions held in the region of the Dolomites.

    This paper presents findings from a collaborative inquiry project that explored teaching approaches that highlight the significance of multilingualism, multimodality, and multiliteracies in classrooms with high numbers of English language learners (ELLs). The research took place in an inner city elementary school with a large population of recently arrived and Canadian-born linguistically and culturally diverse students from Gambian, Indian, Mexican, Sri Lankan, Tibetan and Vietnamese backgrounds, as well as a recent wave of Roma students from Hungary. A high number of these students were from families with low-SES. The collaboration between two Grade 3 teachers and university-based researchers sought to create instructional approaches that would support students’ academic engagement and literacy learning. In this paper, we described one of the projects that took place in this class, exploring how a descriptive writing unit could be implemented in a way that connected with students’ lives and enabled them to use their home languages, through the creation of multiple texts, using creative writing, digital technologies, and drama pedagogy. This kind of multilingual and multimodal classroom practice changed the classroom dynamics and allowed the students access to identity positions of expertise, increasing their literacy investment, literacy engagement and learning.

    Industries nowadays continuously produce new types of inks for markers and pens, so new different graffiti appear . In this paper laser cleaning tests on 41 new marker and pen types ( fluorescent, permanent, water-based, acrylic tempera, metallic paint, waterproof inks ), applied into laboratory on different litho- type samples (Chianca, Travertino di Roma, Tufo Carparo fine grain, Sabbie), typical stones employed in much more monuments in Puglia and Italian architectures were carried out. The same ones, were exposed for twelve months to outdoor ageing, subject to sunshine, rain, wind, IR and UV solar radiations. Ablation experiments and tests by using different cleaning techniques, each one in Dry and Wet condition (classic technique, Daurelio technique 1 and Daurelio technique 2 and others new techniques) and two different Nd:YAG laser systems (Palladio by QUANTA SYSTEM and SMART CLEAN II by EL.EN.), were adopted. The experimental modes, N-Mode (1064nm - 150, 300 and 500 μs pulse duration), Q-Switch (1064nm - 8 ns pulse duration) and SFR (Short Free Running - 1064 nm - 40 to 110μs pulse duration) were tested on each marked stones. It was found that according to the different ink types and stone substrate, Q-Switch laser cleaning ablation with optimized laser technique are the best solution to marker an pen graffiti removal. The work is still in progress.

    In 2008, nationwide investigations of a Salmonella serotype Saintpaul outbreak led first to consumer warnings for Roma and red round tomatoes, then later for jalapeño and serrano peppers. In New Mexico, where there were a large number of cases but no restaurant-based clusters, the NM Department of Health and the Indian Health Service participated with CDC in individual-level and household-level case-control studies of infections in New Mexico and the Navajo Nation. No food item was associated in the individual-level study. In the household-level study, households with an ill member were more likely to have had jalapeño peppers present during the exposure period and to have reported ever having serrano peppers in the household. This report illustrates the complexity of this investigation, the limitations of traditional individual-level case-control studies when vehicles of infection are ingredients or commonly eaten with other foods, and the added value of a household-level study.

    TMEM70 is involved in the biogenesis of mitochondrial ATP synthase and mutations in the TMEM70 gene impair oxidative phosphorylation. Herein, we report on pathology and treatment of ATP synthase deficiency in four siblings. A consanguineous family of Roma (Gipsy) ethnic origin gave birth to 6 children of which 4 were affected presenting with dysmorphic features, failure to thrive, cardiomyopathy, metabolic crises, and 3-methylglutaconic aciduria as clinical symptoms. Genetic testing revealed a homozygous mutation (c.317-2A>G) in the TMEM70 gene. While light microscopy was unremarkable, ultrastructural investigation of muscle tissue revealed accumulation of swollen degenerated mitochondria with lipid crystalloid inclusions, cristae aggregation, and exocytosis of mitochondrial material. Biochemical analysis of mitochondrial complexes showed an almost complete ATP synthase deficiency. Despite harbouring the same mutation, the clinical outcome in the four siblings was different. Two children died within 60 h after birth; the other two had recurrent life-threatening metabolic crises but were successfully managed with supplementation of anaplerotic amino acids, lipids, and symptomatic treatment during metabolic crisis. In summary, TMEM70 mutations can cause distinct ultrastructural mitochondrial degeneration and almost complete deficiency of ATP synthase but are still amenable to treatment. PMID:26550569

    Lead, cadmium, arsenic, and zinc were quantified in mine wastes and in soils mixed with mine wastes. Metal concentrations were found to be heterogeneous in the wastes. Iceberg lettuce, Cherry Belle radishes, Roma bush beans, and Better Boy tomatoes were cultivated in mine wastes and in waste-amended soils. Lettuce and radishes had 100% survival in the 100% mine waste treatments compared to 0% and 25% survival for tomatoes and beans, respectively. Metal concentrations were determined in plant tissues to determine uptake and distribution of metals in the edible plant parts. Individual soil samples were collected beneath each plant to assess metal content in the immediate plant environment. This analysis verified heterogeneous metal content of the mine wastes. The four plant species effectively accumulated and translocated lead, cadmium, arsenic, and zinc. Tomato and bean plants contained the four metals mainly in the roots and little was translocated to the fruits. Radish roots accumulated less metals compared to the leaves, whereas lettuce roots and leaves accumulated similar concentrations of the four metals. Lettuce leaves and radish roots accumulated significantly more metals than bean and tomato fruits. This accumulation pattern suggests that consumption of lettuce leaves or radish roots from plants grown in mine wastes would pose greater risks to humans and wildlife than would consumption of beans or tomatoes grown in the same area. The potential risk may be mitigated somewhat in humans, as vegetables grown in mine wastes exhibited stunted growth and chlorosis.

    The realization of low-cost instruments with high technical performance is a goal that deserves some efforts in an epoch of fast technological developments; indeed, such instruments can be easily reproduced and therefore allow new research programs to be opened in several observatories. We realized a fast optical photometer based on the SiPM technology, using commercially available modules. Using low-cost components, we have developed a custom electronic chain to extract the signal produced by a commercial MPPC module produced by Hamamatsu Photonics, in order to obtain submillisecond sampling of the light curve of astronomical sources (typically, pulsars). In the early 2011 February, we observed the Crab pulsar with the Cassini telescope with our prototype photometer, deriving its period and power spectrum and the shape of its light curve, in very good agreement with the results obtained in the past with other instruments. Based on observations made with the 152 cm Cassini telescope at the Loiano station of the Bologna Observatory and with the 50 cm telescope of the Università di Roma "La Sapienza" at Vallinfreda (Rome).

    The aim of this study was to evaluate the impact of health care planning and management guidelines, elaborated by the Lazio regional healthcare authority, on the organizational structure and operational processes of local health authorities and, more specifically, of the Roma C local health authority. The guidelines are made up of three volumes and mainly describe an operational model, rather than being a set of standard references aimed at standardizing the quality of information low systems in local healthcare authorities. The guidelines are essentially a didactic text, and were elaborated by a consulting firm, Engineering Management Consulting, on behalf of the Lazio regional authority. In the first section, the main concepts are defined, while in subsequent sections, detailed models regarding the specific subject matter are described. Although the guidelines represent a useful tool in the process of converting local health authorities of the Lazio region into "business" organizations, so far they have been of use only in the first phase of assessment of different organizational models for healthcare planning and management. There is still a long way ahead towards defining standard procedures and references for describing activities and costs. This is what should hopefully be achieved briefly and which will necessarily require the introduction of a data warehouse and business intelligence software that will allow monitoring of activities and making short term predictions through the use balanced scorecards and data mining.

    On the basis of cosmic ray and atmospherice lectric field one minute data obtained by NM and EFS ofE milio Segre' Observatory (hight 2025 m above s.l., cut-offr igidity for vertical direction 10.8 GV) we determine thea tmospheric electric field effect in CR for total neutroni ntensity and for multiplicities m ≥1, m ≥2, m ≥3, m ≥4,m ≥5, m ≥6, m ≥7, and m ≥8, as well as for m=1, m=2,m =3, m=4, m=5, m=6, and m=7. For comparison ande xcluding primary CR variations we use also data obtainedb y NM of University "Roma Tre" (about sea level, cut-off rigidity 6.7 GV). According to the theoretical calculations of Dorman and Dorman (1995) the electric field effect in the NM counting rate must be caused mainly by catching ofs low negative muons by lead nucleus with escaping fewn eutrons. As it was shown in Dorman et al. (1999), theb iggest electric field effect is expected in the multiplicitym =1, much smaller in m=2 and negligible effect is expected in higher multiplicities. We will control this conclusion ont he basis of our experimental data. Obtained results give a possibility to estimate total acceleration and deceleration of CR particles by the atmospheric electric field._

    We combined multi-wavelength data for blazars from the Roma-BZCAT catalog and analyzed hundreds of X-ray spectra. We present the fluxes and spectral energy distributions (SEDs), in 12 frequency bands from radio to γ-rays, for a final sample of 2214 blazars. Using a model-independent statistical approach, we looked for systematic trends in the SEDs; the most significant trends involved the radio luminosities and X-ray spectral indices of the blazars. We used a principal component analysis (PCA) to determine the basis vectors of the blazar SEDs and, in order to maximize the size of the sample, imputed missing fluxes using the K-nearest neighbors method. Using more than an order of magnitude more data than was available when Fossati et al. first reported trends of SED shape with blazar luminosity, we confirmed the anti-correlation between radio luminosity and synchrotron peak frequency, although with greater scatter than was seen in the smaller sample. The same trend can be seen between bolometric luminosity and synchrotron peak frequency. Finally, we used all of the available blazar data to determine an empirical SED description that depends only on the radio luminosity at 1.4 GHz and the redshift. We verified that this statistically significant relation was not a result of the luminosity–luminosity correlations that are natural in flux-limited samples (i.e., where the correlation is actually caused by the redshift rather than the luminosity).

    From 29 June to July 6, 2003, the ROMA-Svalrak (Rocketborne Observations of the Middle Atmosphere at the Svalrak facilities) sounding rocket campaign took place at Ny-Alesund (Spitsbergen, geographical coord. 79oN, 12oE, geomagnetic coord. 76oN, 110oE). Three sounding rockets were launched to study neutral air turbulence and small scale plasma dynamics around polar mesosphere summer echoes (PMSE). During all three flights both PMSE and plasma instability events were observed. It is known that small-scale field aligned structures in the E-region plasma density can be created by unstable electromagnetic waves. The mechanism responsible for creating the structures causing radar echoes (PMSE) is believed to be neutral air turbulence in the presence of heavy charged particles. E-region plasma irregularities recorded during the last rocket flight (labeled RO-MI-03) were observed only during the upleg of the trajectory but not during the downleg. Also, on the upleg there was no clear spatial separation between PMSE and the plasma instability regions. In the current paper we consider this transition region in detail.

    On 10 March 2010, due to the heavy rainfall that occurred on the previous days, the Montaguto earthflow reactivated, involving the road SS 90 "Delle Puglie", as had happened previously in May 2005 and in September 2009, and reaching the Roma-Bari railway. This determined a special attention of the National Civil Protection Department and a widespread monitoring and analysis program was initiated. A monitoring activity using GB-InSAR (Ground Based Interferometric Synthetic Aperture Radar) system began, in order to investigate the landslide kinematics, to plan urgent safety measures for risk mitigation and to design long term stabilization work. In this paper the GB-InSAR monitoring system results and its applications in the Observational Method (OM) approach are presented. The paper also highlights how the OM based on the GB-InSAR technique can produce savings in cost and time on engineering projects, without compromising safety, and how it can also benefit the geotechnical community by increasing scientific knowledge. This study focuses on the very much active role played by the monitoring activities, in both the design and plan modifications; with a special consideration for the emergency phase.

    The most commonly used method for serotyping Salmonella spp. is based on the Kaufmann-White scheme, and is composed of serological reactions using antibodies to LPS agglutinins. The multiplex PCR used in this investigation was established by Kim et al. to serotype the 30 most common clinical Salmonella serotypes, as determined by CDC. The PCR assay consists of two five-plex reactions and a single two-plex PCR reaction, based on six genetic loci from Salmonella enterica serotype Typhimurium and four loci from S. enterica serotype Typhi. In this investigation, we further evaluated the method for serotyping Salmonella spp. using a reference collection, environmental samples collected from a Mid-Atlantic region tomato farm study, four food matrices spiked with different Salmonella serotypes and a proficiency test. The PCR assay was first evaluated using DNA isolated from pure cultures of isolates obtained from various clinical and environmental samples, and then DNA isolated from broth cultures of food matrices of "Red round" and Roma tomatoes, Romaine lettuce, green onions and Serrano peppers spiked with serotypes Newport, Typhimurium, Javiana and Saintpaul, respectively. The results showed that the PCR assay correctly serotyped Salmonella spp. from the clinical, environmental, spiked food matrices, and proficiency test samples. These findings are significant because the PCR assay was successful in the identification of Salmonella in the spiked samples in a broth culture containing other non-salmonella organism. This method may be a useful resource for the food safety community. PMID:22608224

    Quarries, caves and mines often contain fossils. During the '30s in Rome, the urban expansion needs for building materials such as gravel, sand and clay were extracted from quarries that surrounded the city. One of these quarries in particular, in the area of Saccopastore (Nomentana area 3 km from the University Sapienza Roma) returned an ancient human fossil skull belonging to a Neanderthal (most likely a female) who lived in Latium about 120,000 years ago. Detailed studies of this fossil were carried out by Sergio Sergi, the son of the founder of the Museum of Anthropology in Rome, Giuseppe Sergi. The museum was founded in 1884 and was later transferred to the University City (1934) where it is still located. Professor Maria Luana Belli, a science teacher in the Liceo Scientifico "G. Keplero" is a volunteer and collaborator with the Museum "G. Sergi", and she and her students retrace the places of the discovery on the trail of the Neanderthals, for understanding the evolution of the territory in a perspective of interdisciplinary teaching.

    Following Snyderman and Rothman (1987, 1988), we surveyed expert opinions on the current state of intelligence research. This report examines expert opinions on causes of international differences in student assessment and psychometric IQ test results. Experts were surveyed about the importance of culture, genes, education (quantity and quality), wealth, health, geography, climate, politics, modernization, sampling error, test knowledge, discrimination, test bias, and migration. The importance of these factors was evaluated for diverse countries, regions, and groups including Finland, East Asia, sub-Saharan Africa, Southern Europe, the Arabian-Muslim world, Latin America, Israel, Jews in the West, Roma (gypsies), and Muslim immigrants. Education was rated by N = 71 experts as the most important cause of international ability differences. Genes were rated as the second most relevant factor but also had the highest variability in ratings. Culture, health, wealth, modernization, and politics were the next most important factors, whereas other factors such as geography, climate, test bias, and sampling error were less important. The paper concludes with a discussion of limitations of the survey (e.g., response rates and validity of expert opinions). PMID:27047425

    Novel selective histone deacetylase 6 (HDAC6) inhibitors using the quinazoline as the cap were designed, synthesized, and evaluated for HDAC enzymatic assays. N-Hydroxy-4-(2-methoxy-5-(methyl(2-methylquinazolin-4-yl)amino)phenoxy)butanamide, 23bb, was the most potent selective inhibitor for HDAC6 with an IC50 of 17 nM and showed 25-fold and 200-fold selectivity relative to HDAC1 and HDAC8, respectively. In vitro, 23bb presented low nanomolar antiproliferative effects against panel of cancer cell lines. Western blot analysis further confirmed that 23bb increased acetylation level of α-tubulin in vitro. 23bb has a good pharmacokinetic profile with oral bioavailability of 47.0% in rats. In in vivo efficacy evaluations of colorectal HCT116, acute myelocytic leukemia MV4-11, and B cell lymphoma Romas xenografts, 23bb more effectively inhibited the tumor growth than SAHA even at a 4-fold reduced dose or ACY-1215 at the same dose. Our results indicated that 23bb is a potent oral anticancer candidate for selective HDAC6 inhibitor and deserves further investigation. PMID:26443078

    Different socioeconomic strata of Roman imperial age are represented by two large dental samples recovered from archaeological excavations near Rome, Italy. Teeth are investigated for crown dimensions and morphological variants. One sample, comprising 1,465 permanent teeth, represents the rural town of Lucus Feroniae (LFR) and is mainly composed of slaves and war veterans. The other, comprising 734 teeth from the Isola Sacra necropolis at Portus Romae (NIS), represents the "middle class" segment of an urban population. Both series show small dental dimensions and fit at the lower end of the trend toward dental reduction in Europe from the Upper Paleolithic to the historical times. The urban sample is less variable metrically and less sexually dimorphic than the rural one. The analysis of discrete crown traits shows absence of rare phenotypic variants in both series. The urban sample is also less variable in this last respect, suggesting that the gene pool of this particular "stratum" of the NIS population was more homogeneous than that of LFR. The occurrence of enamel hypoplasia indicates that metabolic stress during growth and development was similar in LFR and NIS. The overall set of available data is evaluated in the light of the history of the two Roman sites and the composition of each population. PMID:9140539
