Abnormalities on 1q and 7q are associated with poor outcome in sporadic Burkitt's lymphoma. A cytogenetic and comparative genomic hybridization study.

Comparative genomic hybridization (CGH) studies have demonstrated a high incidence of chromosomal imbalances in non-Hodgkin's lymphoma. However, the information on the genomic imbalances in Burkitt's Lymphoma (BL) is scanty. Conventional cytogenetics was performed in 34 cases, and long-distance PCR for t(8;14) was performed in 18 cases. A total of 170 changes were present with a median of four changes per case (range 1-22). Gains of chromosomal material (143) were more frequent than amplifications (5) or losses (22). The most frequent aberrations were gains on chromosomes 12q (26%), Xq (22%), 22q (20%), 20q (17%) and 9q (15%). Losses predominantly involved chromosomes 13q (17%) and 4q (9%). High-level amplifications were present in the regions 1q23-31 (three cases), 6p12-p25 and 8p22-p23. Upon comparing BL vs Burkitt's cell leukemia (BCL), the latter had more changes (mean 4.3 +/- 2.2) than BL (mean 2.7 +/- 3.2). In addition, BCL cases showed more frequently gains on 8q, 9q, 14q, 20q, and 20q, 9q, 8q and 14q, as well as losses on 13q and 4q. Concerning outcome, the presence of abnormalities on 1q (ascertained either by cytogenetics or by CGH), and imbalances on 7q (P=0.01) were associated with a short survival.

Poor communication skills means high risk for aviation safety

Este artigo analisa diferentes tipos de comunicação no ambiente de negócios da aviação civil. Para tanto, utilizou-se uma abordagem qualitativa, delineada por análise documental dos relatórios das agencias governamentais. A comunicação é um sistema complexo que consiste em comunicação verbal, não verbal, escrita, falada e eletrônica. Na aviação, ela é um fator crucial ao enfrentamento de situações de alto risco. Os resultados obtidos indicam que lacunas de comunicação entre os indivíduos que atuam nas operações aeronáuticas e aeroviárias contribuem para a maior parte dos acidentes e incidentes ocorridos. As conclusões pontuam que as habilidades de comunicação são tão importantes quanto às habilidades técnicas e enfatizam a emergência do treinamento em habilidades de comunicação aos profissionais da aviação, possibilitando-os detectar ameaças e comunicar claramente a necessidade de apoio para o enfrentamento de riscos. É imperativo adotar as ações requeridas pela filosofia do Sistema de Gestão de Segurança, visando gerar comportamento seguro.

Improving income and livelihood of poor farming household in Bangladesh through adoption of improved aquaculture technologies and varieties

Fish are an important part of Bangladeshi culture and diet. Bangladesh ranks among the top five freshwater fish producers in the world. Fish are abundant in the thousands of rivers, ponds, lakes and seasonal floodplains across the country. They are a major source of protein for people living near these water bodies. In Bangladesh, many households depend on fish farming for their livelihood. By growing fish in homestead ponds, households have a consistent supply of nutritious fish and can sell the surplus for an income. The USAID-funded Cereal Systems Initiative for South Asia in Bangladesh (CSISA-BD) aimed to increase the income of farming households through increased productivity of aquaculture systems. Key activities of the project included developing and disseminating appropriate improved agricultural technology and quality fish seeds to improve livelihoods, food security and nutrition.

Pro‐poor tourism in a first world urban setting: case study of Glasgow Govan

This research investigates pro-poor tourism (PPT), which has only been considered in a third world context, in a first world country, determining whether PPT principles are being used to alleviate poverty in a developed location, Glasgow Govan, in Scotland. The research develops and applies a new PPT principles tool to regeneration projects in the area and reveals a significant level of PPT application there. The findings suggest that PPT can be an over-complication of a common sense development approach that any responsible government should promote. The results also question the validity of community based tourism initiatives.

The Political and Social Dynamics of Poverty, Poor Relief and Health Care in Early-Modern Portugal

By the end of the fifteenth century most European countries had witnessed a profound reformation of their poor relief and health care policies. As this book demonstrates, Portugal was among them and actively participated in such reforms. Providing the first English language monograph on this topic, Laurinda Abreu examines the Portuguese experience and places it within the broader European context. She shows that, in line with much that was happening throughout the rest of Europe, Portugal had not only set up a systematic reform of the hospitals but had also developed new formal arrangements for charitable and welfare provision that responded to the changing socioeconomic framework, the nature of poverty and the concerns of political powers. The defining element of the Portuguese experience was the dominant role played by a new lay confraternity, the confraternity of the Misericórdia, created under the auspices of King D. Manuel I in 1498. By the time of the king's death in 1521 there were more than 70 Misericórdias in Portugal and its empire, and by 1640, more than 300. All of them were run according to a unified set of rules and principles with identical social objectives. Based upon a wealth of primary source documentation, this book reveals how the sixteenth-century Portuguese crown succeeded in implementing a national poor relief and health care structure, with the support of the Papacy and local elites, and funded principally through pious donations. This process strengthened the authority of the royal government at a time which coincided with the emergence of the early modern state. In so doing, the book establishes poor relief and public health alongside military, diplomatic and administrative authorities, as the pillars of centralisation of royal power.

Why is Asari (= Manila) clam Ruditapes philippinarum fitness poor in Arcachon Bay: a meta-analysis to answer?

Asari (= Manila) clam, Ruditapes philippinarum, is the second bivalve mollusc in terms of production in the world and, in many coastal areas, can beget important socio-economic issues. In Europe, this species was introduced after 1973. In Arcachon Bay, after a decade of aquaculture attempt, Asari clam rapidly constituted neo-naturalized population which is now fished. However, recent studies emphasized the decline of population and individual performances. In the framework of a national project (REPAMEP), some elements of fitness, stressors and responses in Arcachon bay were measured and compared to international data (41 publications, 9 countries). The condition index (CI=flesh weight/shell weight) was the lowest among all compared sites. Variation in average Chla concentration explained 30% of variation of CI among different areas. Among potential diseases, perkinsosis was particularly prevalent in Arcachon Bay, with high abundance, and Asari clams underwent Brown Muscle Disease, a pathology strictly restricted to this lagoon. Overall element contamination was relatively low, although arsenic, cobalt, nickel and chromium displayed higher values than in other ecosystems where Asari clam is exploited. Finally, total hemocyte count (THC) of Asari clam in Arcachon Bay, related to the immune system activity, exhibited values that were also under what is generally observed elsewhere. In conclusion, this study, with all reserves due to heterogeneity of available data, suggest that the particularly low fitness of Asari clam in Arcachon Bay is due to poor trophic condition, high prevalence and intensity of a disease (perkinsosis), moderate inorganic contamination, and poor efficiency of the immune system.

The young, educated, minorities and the poor move out from south central Ethiopia

High population growth fragmented rural landholdings leading to low harvests and crop yields per acre per annum creating surplus labour that may resort to migration as a coping mechanism in least developing countries including Ethiopia. The main aim of the study is to assess trends and differentials of out-migration in south central Ethiopia. The Butajira demographic surveillance system database from 1987 to 2008 was used to conduct event history analysis. There were 3.97 out-migrations per 100 person years. Probability of out-migration was higher among males, teenagers, the youth, completed primary and secondary plus education; not in marital union; Christians, urbanites; lived in rented and owed house compared to their respective counterparts. The higher chances of out-migration among these groups may have social and economic significance.

Low Test Scores in Latin America: Poor Schools, Poor Families, or Something Else?

Latin American students consistently score low on international tests of cognitive skills. In the PISA 2012 results, students in seven Latin American countries had an average score of 395, or about 100 points lower than the average score of 497 in four Scandinavian countries. We examine why Latin American scores are lower and conclude that 50 points are explained by Latin American families’ lower average educational and socioeconomic characteristics, 25 points are explained by Latin America’s weak cultural orientation toward reading books, and the remaining 25 points are explained by the lower effectiveness of educational systems in teaching cognitive skills.

Avaliação do efeito de particulados sólidos na eficiência de um inibidor de corrosão recomendado para meios salinos com CO2

The main problem on the exploration activity on petroleum industry is the formation water resulted on the fields producing. The aggravating of this problem is correlated with the advancing technologies used on the petroleum extractions and on its secondary approach objecting the reobtainment of this oil. Among the main contaminants of the water formation are corrosives gases such as: O2, CO2 and H2S, some solids in suspension and dissolved salts. Concerning to those gases the CO2 is the one that produce significant damage for carbon steel on corrosion process of the petroleum and gas industries. Corrosion inhibitors for carbon steel in formation water is one of the most used agents in control of those damages. In this context, the poor investigations of carbon steel corrosion proceeding from solids in suspension is an opened field for studies. On this work the inhibitor effect of the commercial CORRTREAT 703 was evaluated on some specific solids in suspension at saline medium containing 10.000 ppm of de-aerated chloride using CO2 until non oxygen atmosphere been present. For that, quartz, calcium carbonate, magnetite and iron sulphide were subjected to this investigation as the selected solids. The effect of this inhibitor on corrosion process correlated with those specific solids, was measured using electrochemical (resistance of linear polarization and galvanic pair) and gravimetrical techniques. During all the experimental work important parameters were monitored such as: pH, dissolved oxygen, temperature, instantaneous corrosion rate and galvanic current. According to the obtained results it was proved that the suspension solids calcium carbonate and iron sulphide decrease the corrosion process in higher pH medium. Meanwhile the quartz and magnetite been hardness increase corrosion by broking of the passive layer for erosion. In the other hand, the tested inhibitor in concentration of 50 ppm, showed to be effective (91%) in this corrosion process

Comparison of access to medicines between Klang Valley and East Coast of peninsular Malaysia for children living in poor households

Purpose: To compare access to medicines in children living in poor households (income of USD1/person/day) between urbanised Klang Valley and rural East Coast of Peninsular Malaysia. Methods: A semi-structured interview was conducted with caregivers to determine demographics, access to medicines, knowledge, attitude and practice of parents in obtaining medicines for children. Results: There was no significant difference socio-demographically between poor households in Klang Valley (N = 58) and East Coast (N = 40). The study found that access to medicine for children (N = 325) in the households was adequate, where all households that reported illness in the children over the last 1 month and the last 6 month periods, obtained medicines and 99 % of the children were fully immunized. Qualitative analysis showed that poor households face several barriers in accessing medicines for their children such as financial, transportation, physical and attitudinal. Conclusion: Access to medicines for children living in poor households in both areas were similar and adequate. However, barriers to access remain and further studies are required.
