    Sporotrichoid cutaneous leishmaniasis is due to dissemination of amastigotes via the lymphatics to the subcutaneous tissues. A comparison was made between the potential to disseminate by this route of 2 parasites of different zymodemes in Sudan and Saudi Arabia. In Sudan cutaneous leishmaniasis...... is caused by Leishmania major zymodeme LON-1, and in Saudi Arabia by L. major LON-4. Sporotrichoid leishmaniasis was significantly more common in Sudan, occurring in 23% of patients compared with 10% in Saudi Arabia. Lymph node involvement was slightly more prevalent in the Sudan. Clinical and pathological...... differences between subcutaneous nodules, particularly when they ulcerate, and multiple primary cutaneous lesions are described and treatment of localized and sporotrichoid leishmaniasis is discussed. The pathological features of the primary lesions in the Sudan and Saudi Arabia were similar....

    Tomato is an important vegetable crop and its production is adversely affected by leaf curl disease caused by begomovirus. Leaf curl disease is a serious concern for tomato crops caused by begomovirus in Jeddah, Kingdom of Saudi Arabia. Tomato leaf curl disease has been shown to be mainly caused either by tomato leaf curl Sudan virus or tomato yellow leaf curl virus as well as tomato leaf curl Oman virus. Many tomato plants infected with monopartite begomoviruses were also found to harbor a symptom enhancing betasatellites. Here we report the association of tomato leaf curl Sudan virus causing leaf curl disease of tomato in Jeddah, Kingdom of Saudi Arabia. The complete genome sequence analysis showed highest (99.9 %) identity with tomato leaf curl Sudan virus causing leaf curl disease in Arabian Peninsula. In phylogenetic relationships analysis, the identified virus formed closest cluster with tomato leaf curl Sudan virus. In recombination analysis study, the major parent was identified as tomato leaf curl Sudan virus. Findings of this study strongly supports the associated virus is a variant of tomato leaf curl Sudan virus causing disease in Sudan, Yemen and Arabian Peninsula. The betasatellites sequence analysis showed highest identity (99.8 %) with tomato leaf curl betasatellites-Amaranthus-Jeddah. The phylogenetic analysis result based on betasatellites formed closed cluster with tomato yellow leaf curl Oman betasatellites. The importance of these findings and occurrence of begomovirus in new geographic regions causing leaf curl disease of tomato in Jeddah, Kingdom of Saudi Arabia are discussed. PMID:27366765

    1984-05-01

    The Sudan currently has a population of 18,618,000, with an annual rate of population growth of 3.1% and a rate of natural increase of 2.8%. Population size estimates for the year 2000 range from 32,064,000-33,762,000. The Sudan does not have an explicit policy to modify population growth, although the government is currently in the early stages of formulating a population policy. The current population growth rate is considered satisfactory because of the lack of population pressure on presently developed land, large areas of undeveloped land and unutilized agricultural potential, and low levels of open unemployment. However, the government seeks to modify spatial distribution to attain a better balance between population and resources. This will be accomplished through social infrastructure investments in rural and desert areas, regional development, sedentarization of nomads, development of new towns, and administrative decentralization. In addition, there is major concern with the high influx of undocumented workers and refugees and the significant emigration of skilled personnel. Life expectancy at birth stands at 45.1 years and the infant mortality rate is 131/1000. Current levels and trends of mortality are considered unacceptably high. Major health problems include schistosomiasis, malaria, malnutrition, infectious childhood diseases, and unsafe water. Primary health care is being prioritized to reduce regional differentials in health status and increase accessibility to health services. The total fertility rate has remained constant at 6-7 births/woman, but the government has been cautious with regard to family planning because of generally negative attitudes of Sudanese women toward birth control. Family planning has been integrated into maternal and child health services, although close to half of all ever-married women have never heard of family planning methods and only 6% of currently married fecund women are contraceptive users.

    Full Text Available Instead of hastening political change, the Syrian uprising has led to greater authoritarianism. At first, president Bashar al-Assad adopted various cosmetic reforms (a party law and constitutional referendum, which were designed more as a survival strategy than a genuine process of political liberalisation. In its first four years, the Syrian crisis has gone from being an anti-authoritarian popular uprising to a proxy war with the active presence of Saudi Arabia, Iran, Qatar and Turkey. Control of the state apparatus on the part of the Alawite minority has been instrumentalised by the Salafist and jihadist groups to intensify sectarianism and claim the establishment of an Islamic State.

    International Nuclear Information System (INIS)

    Saudi Arabia is a country of the first importance because of its oil reserves (26% of the known world reserves) and its oil production: the third of the whole Opec production. This energetic gold mine finances up to 75% of the budget and assures 90% of its exports. The capacity of Saudi Arabia to refine crude oil is now comparable to that of France. Nevertheless the inflexibility of government expenditures makes foreign investors necessary to a balanced industrial development. It is expected that the Board of Trade soon presents some dispositions in order to promote and ease the opening to foreign investors. (A.C.)

    In 1985, Saudi Arabia's population stood at 9.6 million, with an annual growth rate of 2.8%. The infant mortality rate was 78/1000 and life expectancy was 60 years. Literacy was at the 50% level among men and 25% among women. Of the work force of 3 million, 66% are foreign workers. The labor force is distributed as follows: agriculture, 14%; industry, 11%; services, commerce, and government, 53%; construction, 20%; and oil and mining, 2%. The GDP was US$98.1 billion in 1985-86, with an annual growth rate of 8% and a per capita GDP of $9800. Under the impact of rapid economic growth, urbanization has advanced rapidly and 95% of the population is now settled. Saudi Arabia, a monarchy, is divided into 14 provinces that are governed by princes or relatives of the royal family. Oil is the major source of foreign exchange, contributing 81% of government revenues. Ample government funds and foreign exchange resources are available for development, defense, and aid to other Arab and Islamic countries. The government has sought to allocate its petroleum income to transform its relatively undeveloped oil-based economy into that of a modern industrial state while maintaining traditional Islamic values. The standard of living of most Saudis has improved significantly. A shortage of skilled workers at all levels remains the principal obstacle to rapid development. PMID:12178138

    The sedimentology of the Northwestern Sudan consists of lower, middle and upper cycles.The lower and upper cycles are composed of intercalated fluvial and shallow marine facies, whereas the middle cycle consists entirely of fluvial and glaciofluvial facies. The petrographic analysis shows that the lower and upper cycles consist of quartz and lithic arenite sandstones, whereas the middle cycle consists of arkosic and lithic arenite sandstones. The lower and upper cycle sandstones reflect derivation mainly from recycled orogens with minor contribution from craton interior provenances. However, the middle cycle sandstones indicate derivation from basement uplift, transitional and mainly recycled orogens provenances.

All Syrians admitted to a psychiatric hospital in Lebanon between the 1st of January 2009 and the 31st of December 2013 were included. Number of admissions, psychiatric disorders and demographic and clinical data relative to patients were compared between those admitted before and after the crisis. 44 patients were admitted before the crisis and 106 after it. The distribution of diagnosis varied significantly after the crisis (p = 0.056) with the majority of patients being admitted for schizophrenia (37.7 %). The prevalence of suicidal ideation was higher after the crisis (p = 0.03) but suicidal attempts, need for electroconvulsive therapy and length of hospitalization did not differ significantly between both groups. Clinicians should be aware of the possible burden of mental illness in Syrians after the beginning of the Syrian crisis.

    Craniofacial area is apart of the human body which undergoes the greatest changes during development and is characterized by uneven growth. External and internal factors affect the growth and development of craniofacial structures. They are responsible for the occurrence of specific craniofacial characteristics in different races or populations within the same race. The present study investigates the possible differences of the basic head and face shapes between the Croatian and Syrian populations. The sample included 400 subjects of both sexes aged 18-24 years and was divided into a Croatian and a Syrian group with 200 subjects each. Six variables defined according to Martin and Saller were measured by standard anthropometric instruments. The results of the study demonstrated statistically significant differences between our subjects in all variables except face width. The dolichocephalic head type and the mesoprosopic face type were predominant in the Croatian population, while the brachycephalic head type and the euryprosopic face type dominated in the Syrian population.

  1. Uses of radioisotopes in Sudan

    International Nuclear Information System (INIS)

    In this research project, an inventory for the different radioisotopes that were imported by public and private sectors of Sudan in the period between ( 2007-2011) has been set up. These organizations import the appropriates for different but in general we classify them into these applications: Medical, Industrial, Agricultural and Research. However, each broad discipline is subdivided into subgroups. This inventory will help those who are willing to establish research reactors in Sudan on the type and power of the reactors to be purchases according to the actual needs of Sudan with forecasting of the near and for future needs. Also the expenditure that has been spent by these organizations have been estimated for most of the radioisotopes. It was observed that almost 50% of the expenditure went for the fright charges as these radioisotopes need special handling and care by installing a research reactor in Sudan, the cost of purchasing will be cut down several folds. Also it will help in availability of the radioisotopes with very short half lives (hours to days). This will be reflected in the cut down the cost of tests and provision of new tests.(Author)

    1985-01-01

    Sudan is surrounded by eight countries and has marked movement of population across its borders. At one time yaws and syphilis were important public health problems in the Sudan. Following the wide use of penicillin, both diseases were much reduced in prevalence and were no longer public health problems. However, the extensive population movement and particularly the huge influx of refugees across the border pose important potential hazards. The rapid urbanization and the social and cultural changes that followed economic development affected family ties and community behavior and resulted in a marked increase in the prevalence of sexually transmitted diseases, including syphilis. It is difficult to know the true magnitude of the problem because of the poor health information system and coverage. Improvement of the surveillance system is urgently needed, and more attention needs to be paid to treponemal infections. This entails improvement in health services and training of health personnel.

    This paper describes Earth Science Education in Sudan, with particular emphasis on the University of Khartoum. The first geological department in Sudan was founded in 1958 in the University of Khartoum. In the 1980s, six more geological departments have been added in the newer universities. The types of courses offered include Diploma, B.Sc. (General), B.Sc. (Honours), M.Sc. and Ph.D. The Geology programmes are strongly supported by field work training and mapping. Final-year students follow specialised training in one of the following topics: hydrogeology, geophysics, economic geology, sedimentology and engineering geology. A graduation report, written in the final year, represents 30-40% of the total marks. The final assessment and grading are decided with the help of internal and external examiners. Entry into the Geology programmes is based on merit and performance. The number of students who graduate with Honours and become geologists is between 20% to 40% of the initial intake at the beginning of the second year. Employment opportunities are limited and are found mainly in the Government's geological offices, the universities and research centres, and private companies. The Department of Geology at the University of Khartoum has long-standing internal and external links with outside partners. This has been manifested in the training of staff members, the donation of teaching materials and laboratory facilities. The chief problems currently facing Earth Science Education in Sudan are underfunding, poor equipment, laboratory facilities and logistics. Other problems include a shortage of staff, absence of research, lack of supervision and emigration of staff members. Urgent measures are needed to assess and evaluate the status of Earth Science Education in terms of objectives, needs and difficulties encountered. Earth Science Education is expected to contribute significantly to the exploitation of mineral resources and socio-economic development in the Sudan.

    Full Text Available While there were several relatively short uprisings in Northern Africa and the Middle East during the Arab Spring, the dispute between the rebels and government forces in Syria has evolved into a full-scale civil war. We try to predict the length of the Syrian insurgency with a three-stage technique. Using out-of-sample techniques, we first assess the predictive capacity of 69 explanatory variables for insurgency duration. After determining the model with the highest predictive power, we categorize Syria according to the variables in this final model. Based on in-sample approaches, we then predict the duration of the Syrian uprising for three different scenarios. The most realistic point prediction is 5.12 years from the insurgency’s start, which suggests an end date between the end of 2016 and early 2017.

    Generation of new neurons from adult neural stem cells occurs in the dentate gyrus (DG) of the hippocampus and the lateral walls of the lateral ventricles. In this article, we study the neurogenesis that takes place during the hibernation of the Syrian hamster (Mesocricetus auratus). Using a variety of standard neurogenesis markers and 5-bromo-2-deoxyuridine (BrdU) incorporation, we describe a preferential decrease in the proliferation of newborn neurons in the subventricular zone (SVZ) of the hibernating hamsters (torpor) rather than in the hippocampus. Furthermore, we demonstrate that the proliferative capacity is recovered after 3-4days of torpor when arousal is triggered under natural conditions (i.e., not artificially provoked). In addition, we show that tau3R, a tau isoform with three microtubule-binding domains, is a suitable marker to study neurogenesis both in the SVZ and subgranular zone (SGZ) of the Syrian hamster brain.

    Sudan dyes are widely used in industry, and sometimes illegally used as food additives despite their potential toxicity. In this work, the interactions of Sudan II and Sudan IV with bovine hemoglobin (BHb) were investigated by fluorescence, synchronous fluorescence, resonance light scattering (RLS), UV–vis absorption, circular dichroism (CD), and molecular modeling techniques. Binding of Sudan dyes to BHb could cause static quenching of the fluorescence, indicating changes in the microenvironment of tryptophan and tyrosine residues. The binding constants estimated for Sudan II and IV were 1.84×10{sup 4} L mol{sup −1} and 2.54×10{sup 4} L mol{sup −1}, respectively, at 293 K (20 °C). Each protein molecule bound one Sudan molecule approximately. Sudan II and IV were held at the hydrophobic cavity of BHb mainly by hydrophobic interaction. The decrease of α-helix and the increase of β-sheet seen in the CD spectra revealed a conformational alteration of the protein. From all the results, we conclude that Sudan IV has a stronger impact on the structure and function of BHb than that of Sudan II. -- Highlights: • Spectroscopic results show interaction details of Sudan II and IV with BHb. • The interaction of BHb with Sudan dyes is spontaneous with a 1:1 stoichiometry. • Sudan II and IV are located at the hydrophobic cavity of the BHb, and form complexes via hydrophobic interaction. • A stronger influence of bovine hemoglobin is caused by Sudan IV than that of Sudan II.

    The conflict in Syria is a big humanitarian emergency. More than 200,000 Syrians have been killed, with more than half of the population either having been displaced or having immigrated. Healthcare has been interrupted due to the destruction of facilities, a lack of medical staff, and a critical shortage of life-saving medications. It produced suitable conditions leading to the re-emergence of tuberculosis, cutaneous leishmaniasis, polio, and measles. Lebanon and Jordan reported increased rates of tuberculosis among Syrian refugees. Cutaneous leishmaniasis outbreaks were noted not only in Syria but also in Turkey, Jordan, and Lebanon. After a polio-free 15 years, Syria reported a polio outbreak. Ongoing measles outbreaks in the region was accelerated by the conflict. Iraq declared a cholera outbreak among the Syrian refugees. The healthcare facilities of the countries hosting immigrants, mainly Turkey, Lebanon, Jordan, Iraq, and Egypt, are overburdened. The majority of the immigrants live in crowded and unsanitary conditions. Infectious diseases are big challenges for Syria and for the countries hosting immigrants. More structured support from international organizations is needed for the prevention, control, diagnosis, and treatment of infectious diseases. PMID:27063349

    The recovery of Syrian hamsters after split dose application (interval 11 days) was studied on the basis of the weight response and of food uptake. Two periods of weight loss and anorexia can be distinguished, an early one immediately after irradiation and a secondary one 6-10 days later. The secondary response is a function of the radiation dose and allows to distinguish survivors from non-survivors, since it is much more pronounced and longerlasting in the latter than in the former. The first response appears not to be influenced by a previous conditioning irradiation. (orig.)

    Full Text Available This paper examines the attitudes of local communities toward community forestry programmes implemented by a project under the CF approach in Kosti area, based on a survey of 100 people living there. The household was the basic unit of data collection; ten villages were selected as study localities. Ten respondents from each village were randomly chosen for the interview. Frequency distribution results showed that almost all the respondents have a particularly favourable perception of the community forestry programmes implemented and they perceive the best type of management for running these forests which is to be owned and managed by them. They participated in different programe activities and willing to further participation in tree planting activities. Women have possessed positive attitudes towards community forestry although they were not fully involved in community forestry Practices. Stepwise multiple linear regression analysis showed a statistical significant relation between some selected variables (Respondents age, educational level, main occupation, respondents indigenous knowledge, family uses of different forestry products, awareness of causes of forest destruction and finally respondents awareness of environmental problems exerted important influences on the attitudes and participation of respondents. This study suggests that the project and the forest services should continue addressing local development needs, encourage women's participation in community forestry, and work toward dispute settlement of community forest-user groups, if it wants to win the support of local communities for long-term environmental conservation goals.

  2. Ion exchange investigation on the Syrian zeolite

    International Nuclear Information System (INIS)

    We have studied the ion exchange process by using Syrian zeolite from the region of Tell-Assis with four solutions containing these ions: Ag+, NH4+, Pb2+, and Cu2+. It was found that the required time to reach the equilibrium is 6-8 hours, and depends on the type of ion. the exchange capacity mainly depends on the type of ions, and range between 0.5-1.57 m. mol/g. The effect of pH on ion exchange capacity was obvious and the best results were reached when the pH ranged between 5+ will exchange with univalent and bivalent ions in the zeolite, whereas the bivalent ions as Pb+2 will preferentially exchange with the bivalent ions in the zeolite. we concluded that the used zeolite gave good results compared with some known zeolite.

  3. Environment of paleowater in Sudan

    International Nuclear Information System (INIS)

    Many natural and environmental developments created the conditions for paleowater occurrence in Sudan and possibly other areas. The major developments include: geological, structural and climatic. The geological environment includes the formation of Basement Complex (BC), which are the oldest rocks emplaced during Pre-Cambrian to the early Jurassic followed by the severe erosion, magmatism and deformation during the Jurassic. The uncomfortable deposition of the sedimentary rocks started in the Paleozoic and continued in association with the tectonic activities. Structural features resulted from the frequent tectonic activities controlled the configuration and geographical distribution of the sedimentary basins. The NW Central African Shear Zone CASZ, slip fault Wrench Strike to the West of the CASZ and the Garaf Strike Slip fault led to the establishment of depressions and deposition of the Paleozoic and Mesozoic sediments forming the sedimentary basins in Northwest (Sahara), in Southwest (Bagara) and in the east central (R Atbra)of Sudan respectively. The paleoclimatic investigations in the region covering: Lake Chad, the Nile system, Ethiopian Plata, Libya and Egypt suggested humid conditions between 40,000 and 3,000 Bp. The wet period was interrupted by dry periods. The early wet periods were recorded in Lake Chad. The estimated age of Paleowater cluster between 30,000-20,000 and 10,000 and 3000 BP and few ages between 10,000 and 20,000 PB in agreement with the defined dry period between 20,000 and 13,000 BP. The recharge of the Nubian aquifer remains a debatable topic. The so far conducted studies using environmental isotopes and hydrochemistry on the basis of conventional approaches suggest. The infiltration rate of water from the rainfall is estimated at 0.4 and 1.0 mm/y in the arid zones in the north (R Atbra Basin) and increases up to 10.0mm/y in the relatively wet areas in the south (Bagara Basin). The lateral recharge from the Nile system is evident up to

    2015-04-01

    Full Text Available The Republic of South Sudan continues to face considerable challenges in meeting maternal, newborn and child health (MNCH care needs and improving health outcomes. Ongoing instability and population displacement undermine scope for development, and damaged infrastructure, low coverage of health services, and limited government capacity and a human resource base have resulted in a fragmented health system. Despite considerable attention, effort and support, the issues and challenges facing South Sudan remain deep and sustained, and urban–rural disparities are considerable. There is a need to maintain investments in MNCH care and to support developing systems, institutions, and programs. This review of the literature offers a commentary and appraisal of the current MNCH situation in South Sudan. It explores the barriers and challenges of promoting MNCH gains, and identifies priorities that will contribute to addressing the Millennium Development Goals and the emerging health priorities for the post-2015 development agenda.

    2011-01-01

    Summer rains in western and southern Sudan have declined by 10-20 percent since the mid-1970s. Observed warming of more than 1 degree Celsius is equivalent to another 10-20 percent reduction in rainfall for crops. The warming and drying have impacted southern Darfur and areas around Juba. Rainfall declines west of Juba threaten southern Sudan's future food production prospects. In many cases, areas with changing climate are coincident with zones of substantial conflict, suggesting some degree of association; however, the contribution of climate change to these conflicts is not currently understood. Rapid population growth and the expansion of farming and pastoralism under a more variable climate regime could dramatically increase the number of at-risk people in Sudan over the next 20 years.

    Full Text Available Application of new and renewable sources of energy available in Sudan is now a major issue in the future energy strategic planning for the alternative to the fossil conventional energy to provide part of the local energy demand. Like many of the African leaders in renewable energy utilisation, Sudan has a well-defined commitment to continue research, development, and implementation of new technologies. Sustainable low-carbon energy scenarios for the new century emphasise the untapped potential of renewable resources are needed. Rural areas of Sudan can benefit from this transition. The increased availability of reliable and efficient energy services stimulates new development alternatives. It is concluded that renewable environmentally friendly energy must be encouraged, promoted, implemented, and demonstrated by full-scale plant especially for use in remote rural areas.

    Full Text Available Objectives: To review the studied risk factors that linked to aetiology of oral cancer in the Sudan. There have been numerous reports in the increase in the incidence of oral cancer from various parts of the world. A recent trend for a rising incidence of oral cancer, with the absence of the well established risk factors, has raised concern. Although, there are inconsistent data on incidence and demographical factors, studies suggest that the physiologic response to risk factors by men and women vary in different populations.Material and Methods: This review principally examines 33 publications devoted to aetiology of oral cancer in the Sudan, in addition to some risk factors that are commonly practiced in the Sudan.Results: Several studies examining risk factors for oral cancer include tobacco use (Smoked and Smokeless, alcohol consumption, occupational risk, familial risk, immune deficits, virus infection and genetic factors.Conclusions: Toombak use and infection with high risk Human Papilloma Virus (HPV were extensively investigated and linked to the aetiology of oral cancer in Sudan.

    Directory of Open Access Journals (Sweden)

    Zeki BOYRAZ

    2015-08-01

    Full Text Available The on going conflicts and wars in different parts of the world on different dates forced millions of people to migrate. Over 5 million Palestinians still live in the refugee camps built in Lebanon, Syria, Jordan and Paletsine after the war in 1967. Many Albanian, Kosovan, Bosnian, Iraqi and Somalian migrated to various European countries and NortAmerica. Our kins took refuge in our country due to the political oppression they experienced in the balkan states likeGreece, Bulgaria, Romania and Jugoslavia. They still live in our country, particularly in the Marmara region. The main reason of Syrian migration was the armed struggle between the Syria Baas Party and the opponent party who wanted to come to power. The struggle started on March 15th, 2011 and spread all over the country in April, 2011. Consequently, 7.6 million Syrian had to migrate. 1.532 of these Syrian took refuge in Turkey. 235.000 of these migrants live in tent cities in different cities and 1.332 of these migrants dispersed all over the country. Our study takes the Syrian migration toTurkey as an example to draw attention on the migrants and refugees who are forced to migrate because of wars, civil wars and political oppression in their countries. In our study the dispersion of tent cities in Turkey will be examined taking the camps in Akçakale as an example. It’s clear that this Syrian refugee crisis will cause Syrian migrants to be settled in Turkey in the near future.

Although breast cancer incidence is lower in Sub-Saharan African countries than in developed countries, African women are more likely than women in the developed world to be diagnosed at later stages of the disease and, thus, are more likely to die from it. This is due to the lack of awareness by women, accessibility to screening methods, and availability of African-based research findings that would influence decision making at the governmental level. This descriptive study was undertaken to shed light on the type, stage and age distribution of breast cancer at diagnosis in women living in central Sudan encompassing al-Gezira, Blue Nile, White Nile, and Sennar States. Cases comprised 1255 women from central Sudan diagnosed with breast cancer and referred to and treated at Institute of Nuclear Medicine, Molecular Biology, and Oncology, from January 1999 to December 2006. Data revealed that 74% of the women were <50 years old or premenopausal. Invasive ductal carcinoma was the most common pathology (82% and women presenting with stage III or higher tumors that had already metastasized, while ductal carcinoma in situ was the least prevalent (0.5% finding.

  4. Hyperlipidaemia in Saudi Arabia

    International Nuclear Information System (INIS)

    Objective was to determine the prevalence of hyperlipidemia among Saudis of both genders in rural and urban communities. Selected Saudis in the age group of 30-70 years were studied over a 5-year period between 1995 and 2000 in Saudi Arabia. Data were obtained from history, physical examination and analysis of fasting plasma lipids. The data were analyzed to classify individuals with hypercholesterolemia (HC) (total cholesterol >=5.2 mmol/l) and hypertriglyceridemia (HT) (total triglycerides >=1.69 mmol/l). Logistic regression analysis was performed to provide a risk assessment model and correlation with other coronary artery disease (CAD) risk factors. The number of study samples included in the final analysis was 16,819. The prevalence of HC was 54% with mean cholesterol level of 5.4+-1.52 mmol/l. Prevalence of HC among males was 54.9% and 53.2% for females, while 53.4% among urban Saudis and 55.3% for rural Saudis. Hypertriglycemia prevalence was 40.3% with mean triglycerides level of 1.8+-1.29 mmol/l. Males had statistically significant higher HT prevalence of 47.6% compared to 33.7% in females (p<0.0001). Hyperlipidemia is reaching higher prevalence rates in KSA. This finding may suggest that CAD will soon be a major health problem. Reduction in obesity by adopting healthier eating problem habits and increasing physical activity are of considerable importance to our community. (author)

  5. First dinosaurs from Saudi Arabia.

    Directory of Open Access Journals (Sweden)

    Benjamin P Kear

    Full Text Available Dinosaur remains from the Arabian subcontinent are exceedingly rare, and those that have been documented manifest indeterminate affinities. Consequently the discovery of a small, but diagnostic, accumulation of elements from Campanian-Maastrichtian (~ 75 Ma deposits in northwestern Saudi Arabia is significant because it constitutes the first taxonomically identifiable dinosaur material described from the Arabian Peninsula. The fossils include a series of possible lithostrotian titanosaur caudal vertebrae, and some isolated theropod marginal teeth that share unique character states and metric parameters (analyzed using multivariate statistical methods with derived abelisaurids - this is the first justifiable example of a non-avian carnivorous dinosaur clade from Arabia. The recognition of titanosaurians and abelisaurids from Saudi Arabia extends the palaeogeographical range of these groups along the entire northern Gondwanan margin during the latest Cretaceous. Moreover, given the extreme paucity of coeval occurrences elsewhere, the Saudi Arabian fossils provide a tantalizing glimpse into dinosaurian assemblage diversity within the region.

  13. Mapping the potential risk of mycetoma infection in Sudan and South Sudan using ecological niche modeling.

    Directory of Open Access Journals (Sweden)

    Abdallah M Samy

    2014-10-01

    Full Text Available In 2013, the World Health Organization (WHO recognized mycetoma as one of the neglected tropical conditions due to the efforts of the mycetoma consortium. This same consortium formulated knowledge gaps that require further research. One of these gaps was that very few data are available on the epidemiology and transmission cycle of the causative agents. Previous work suggested a soil-borne or Acacia thorn-prick-mediated origin of mycetoma infections, but no studies have investigated effects of soil type and Acacia geographic distribution on mycetoma case distributions. Here, we map risk of mycetoma infection across Sudan and South Sudan using ecological niche modeling (ENM. For this study, records of mycetoma cases were obtained from the scientific literature and GIDEON; Acacia records were obtained from the Global Biodiversity Information Facility. We developed ENMs based on digital GIS data layers summarizing soil characteristics, land-surface temperature, and greenness indices to provide a rich picture of environmental variation across Sudan and South Sudan. ENMs were calibrated in known endemic districts and transferred countrywide; model results suggested that risk is greatest in an east-west belt across central Sudan. Visualizing ENMs in environmental dimensions, mycetoma occurs under diverse environmental conditions. We compared niches of mycetoma and Acacia trees, and could not reject the null hypothesis of niche similarity. This study revealed contributions of different environmental factors to mycetoma infection risk, identified suitable environments and regions for transmission, signaled a potential mycetoma-Acacia association, and provided steps towards a robust risk map for the disease.

    Full Text Available A 14-month-old intact male Syrian hamster was admitted for lethargy and hematuria. A total body radiographic image and abdominal ultrasonography showed the presence of a vesical calculus. During cystotomy, a sterile urine sample was obtained and sent to the diagnostic laboratory along with the urolith for analysis. Urine culture was found negative for bacterial growth, and the urolith was identified as a calcium-oxalate stone. Diet supplementation with palmitoylethanolamide, glucosamine and hesperidin was adopted the day after discharge. One year follow up revealed no presence of vesical calculi. Although this is the report of a single clinical case, this outcome differs from the results reported in the literature characterized by recurrences after few months. Considering the positive outcome and the beneficial properties of palmitoylethanolamide, glucosamine, and hesperidin, these nutritional elements in Syrian hamsters, are recommended to reduce recurrence after surgical treatment of urolithiasis.

    Extracts of the calyces of Hibiscus sabdariffa are widely used in folk medicine to combat many illnesses. The active constituents of the extracts have been shown on several occasions to be anthocyanins. In our current studies the biological activities of an extract of H. sabdariffa calyces purchased in Oman, but grown in Sudan, are being compared with those of the anthocyanins isolated from them, and, for this, the anthocyanin profile of the extract needed to be ascertained. Although several anthocyanins were detected by UHPLC-ESI-MS/MS, delphinidin-3-sambubioside (major) and cyanidin-3-sambubioside were predominant. PMID:25920224

    Global warming has brought great pressure on the environment and livelihood conditions in Sudan and South Sudan. It is desirable to analyze and predict the change of critical climatic variables, such as temperature and precipitation, which will provide valuable reference results for future water resources planning and management in the region. The aims of this study are to test the applicability of the Long Ashton Research Station Weather Generator (LARS-WG) model in downscaling daily precipitation and daily maximum (Tmax) and daily minimum (Tmin) temperatures in Sudan and South Sudan and use it to predict future changes of precipitation; Tmin and Tmax for nine stations in Sudan and South Sudan are based on the SRA2 scenario of seven General Circulation Models (GCMs) outputs for the periods of 2011-2030, 2046-2065, and 2080-2099. The results showed that (1) the LARS-WG model produces good performance in downscaling daily precipitation and excellent performance in downscaling Tmax and Tmin in the study region; (2) downscaled precipitation from the prediction of seven GCMs showed great inconsistency in these two regions, which illustrates the great uncertainty in GCMs' results in the regions; (3) predicted precipitation in rainy season JJA (June, July, and August) based on the ensemble mean of seven GCMs showed a decreasing trend in the periods of 2011-2030, 2046-2065, and 2080-2099 in Sudan; however, an increasing trend can be found in SON (September, October, and November) in the future; (4) precipitation in South Sudan has an increasing trend in most seasons in the future except in MAM (March, April, and May) season in 2011-2030; and (5) predictions from seven GCMs showed a similar and continuous increasing trend for Tmax and Tmin in all three future periods, which will bring severe negative influence on improving livelihoods and reducing poverty in Sudan and South Sudan.

    Conclusion: Due to an absence of published literature in Sudan, much of the data have been recorded from paper records and empirical observations. Prehospital care and injury prevention in the Sudan is a recent initiative, but it is developing into a promising model with many opportunities for improvement. This momentum should be nurtured and requires a purposive, collective collaboration to draw a blueprint for a locally relevant, effective and efficient prehospital system in Sudan. It is hoped that this article will highlight and encourage further progress.

  10. Norm waste in oil and gas industry: The Syrian experience

    International Nuclear Information System (INIS)

    This paper describes the Syrian experience in respect to Naturally Occurring Radioactive Materials (NORM) waste in Syrian oil and gas industry. NORM can be concentrated and accumulated in tubing and surface equipment of oil and gas production lines in the form of scale and sludge. NORM waste (scale, sludge, production water) is therefore generated during cleaning, physical or chemical treatment of streams. Uncontrolled disposal of this type of waste could lead to environmental pollution, and thus eventually to exposure of members of the public. The presence of NORM in Syrian oil fields has been recognized since 1987 and AECS has initiated several studies, in cooperation with oil companies, to manage such type of waste. Three categories of NORM waste in Syrian oil fields were identified. Firstly, hard scales from either decontamination of contaminated equipment and tubular using high-pressure water systems or mechanical cleaning at site are considered to contain the highest levels of radium isotopes (226Ra, 228Ra, 224Ra). Secondly, sludge wastes are generated with large amount but low levels of radium isotopes were found. Thirdly, contaminated soil with 226Ra as a result of uncontrolled disposal of production water was also considered as NORM waste. The first waste type (scale) is stored in Standard storage barrels in a controlled area; the number of barrels is increasing with time. High levels of radium isotopes were found in these scales. The options for disposal of these wastes are still under investigations; one of the most predominant thinking is the re-injection into abundant wells. For sludge waste, plastic lined disposal pits were constructed in each area for temporary storage. Moreover, big gas power stations have been built and operated since the last ten years. Maintenance operations for these stations produce tens of tones of scales containing radon daughters, 210Pb and 210Po with relatively high concentrations. The common practice used to dispose these

    Objective: To investigate the epidemiological factors of tuberculosis (TB) in eastern Sudan. Methods:The socio-demographic and clinical data was retrieved from the database at Kassala hospital during the year of 2011. The medical file of consequent patients who was discharged from the same ward in the hospital was reviewed to act as control for the TB patients. Results:A total of 670 patients were registered at Kassala hospital with clinical, laboratory and radiological evidence proven TB. Pulmonary TB accounted for 73.4%while extra-pulmonary TB was reported in 26.6%of all TB patients. The mean age (SD) was not significantly different between the cases and controls (670 in each arm). TB patients were those who had less education, and the infection more likely common among male patients. Conclusions: Intervention from outside the health field in particular awareness of associated risk factors and improvement of the educational level potentially will strengthen TB control.

  16. Radiochemical studies on environmental radioactivity in Sudan

    International Nuclear Information System (INIS)

    Measurements of uranium and thorium isotopes, 226 Ra, 210 Po, 228 Ra, 40 K and fallout radionuclide 137 Cs in soil samples collected from different districts in Sudan, rock phosphate samples collected from the uro and kurun rock phosphate deposits in the eastern part of the Nuba mountains in Western Sudan, and surface marine sediments and marine organisms collected from the sudanese coastal waters of the Red Sea have been made using a high resolution gamma-spectrometry, radiochemical separation and α spectrometry. The external exposure due to γ radiation from the ground has been calculated. The average exposure was found to be 45.4 ± 21.3 nGy/h, corresponding to the annual dose equivalent of 278 μSv/y. With the exception of some areas, the calculated exposure falls within the global wide range of outdoor radiation exposure given in the UNSCEAR publications. The nation-wide average concentrations of 226 Ra, 238 U, 232 Th, 40 K and 137 Cs determined were 31.6 ± 27, 20.1 ± 16.4, 19.1 ± 8.1, 280.3 ± 137.6 and 4.1 ± 4.3 Bq/Kg, respectively. This shows that there is little contamination due to fallout radioactivity at survey sites. The exchangeable radium fraction constitutes 19-24% of the total radium content. The data show that 238 U and its decay products are the principal contributors of radioactivity in both phosphate deposits at Uro and Kurun. The equivalent mass concentrations of uranium in the Uro rock phosphate fall within the range that could be economically recovered as the by-product of fertilizer industry. The mean activity concentrations weighted by average agricultural consumption of 300 kg/ha of untreated ground rock fertilizer resulted in an annual distribution of 120.63 Bq Ra/m2 with Uro rock and 12.97, 0.21 and 4.24 Bq/m2 respectively, with Kurun rock fertilizer. The external radiation exposure over agricultural areas was estimated 23.41 x 10 -9 Gy/h and 2.59 x 10 -9 Gy/h at 1 m above ground level for Uro and Kurun rock phosphate fertilizers

    Four eucalypts (Eucalyptus camaldulensis, Eucalyptus microtheca, Eucalyptus tereticornis and Eucalyptus citriodora) grown in Sudan were examined for their suitability for pulping and papermaking with different alkaline methods. Their physical, morphological and chemical characteristics are reported. The pulping trials with E. citriodora and E. tereticornis were carried out using the kraft-AQ, soda-AQ, modified AS/AQ (ASA), ASAM and kraft methods. For the other two species, only the ASAM and the kraft process were applied. ASAM pulping gave the best results in terms of yield, degree of delignification, mechanical and optical pulp properties. The best pulps, obtained in kraft and ASAM cooking of E. citriodora, were bleached to 88% ISO brightness in a totally chlorine free bleaching sequence (OQ1O/PQ2P). The bleached pulps, especially the ASAM pulp, showed good papermaking properties and would be suitable for manufacture of writing and printing grades of paper. PMID:15935655

    Being an industrial dye, the Sudan I may have a toxic effect after oral intake on the body, and has recently been shown to cause cancer in rats, mice and rabbits. Because China and some other countries have detected the Sudan I in samples of the hot chilli powder and the chilli products, it is necessary to study the characteristics of this dye. As one kind of molecule scattering spectroscopy, Raman spectroscopy is characterized by the frequency excursion caused by interactions of molecules and photons. The frequency excursion reflects the margin between certain two vibrational or rotational energy states, and shows the information of the molecule. Because Raman spectroscopy can provides quick, easy, reproducible, and non-destructive analysis, both qualitative and quantitative, with no sample preparation required, Raman spectroscopy has been a particularly promising technique for analyzing the characteristics and structures of molecules, especially organic ones. Now, it has a broad application in biological, chemical, environmental and industrial applications. This paper firstly introduces Sudan I dye and the Raman spectroscopy technology, and then describes its application to the Sudan I. Secondly, the fingerprint spectra of the Sudan I are respectively assigned and analyzed in detail. Finally, the conclusion that the Raman spectroscopy technology is a powerful tool to determine the Sudan I is drawn.

  19. Sudan: the human price of oil

    International Nuclear Information System (INIS)

    This series of eight information bulletins by Amnesty International is intended to draw attention to the link between the massive human rights violations by the security forces of the Government of Sudan and various government-allied militia forces, and the oil operations by foreign companies (which include Canada's Talisman Energy, Denim Pipeline Construction Ltd., and Roll'n Oil Field Industries). The human rights violations cited by Amnesty International include atrocities and the forcible internal displacement of large populations of local people living in the oil fields and surrounding areas. It is alleged that the foreign oil companies involved in this lucrative operation expect the Sudanese government to provide a secure environment and protect oil company staff and assets, and turn a blind eye to human rights violations by the government security forces in the name of protecting the security of the oil-producing areas. In raising awareness of the problem, Amnesty International hopes to establish a dialogue with the foreign oil companies and sensitize them to their responsibilities to promote a better human rights environment in the areas where they are active in oil exploration and extraction. The information bulletins provide a background to the problem; detail the human rights violations committed in the name of oil; establish the link between oil, weapons purchases by the Sudanese government and human rights violations; describe the oil companies and their responsibilities and international standards on internal displacement of populations; and makes recommendations to the Government of Sudan, to the armed opposition groups, to the oil companies and to the international community at large to bring an end to the human rights violations that over the last three decades have cost tens of thousands of lives and displaced hundreds of thousands of people

    The crisis in Syria has forced more than 4 million people to find refuge outside Syria. In Lebanon, in 2015, the refugee population represented 30 % of the total population. International health assistance has been provided to refugee populations in Lebanon. However, the current humanitarian system has also contributed to increase fragmentation of the Lebanese health system. Ensuring universal health coverage to vulnerable Lebanese, Syrian and Palestinian refugees will require in Lebanon to redistribute the key functions and responsibilities of the Ministry of Health and its partners to generate more coherence and efficiency.

    Millions of people exchange user-generated information through online social media (SM) services. The prevalence of SM use globally and its growing significance to the evolution of events has attracted the attention of the Army and other agencies charged with protecting national security interests. The information exchanged in SM sites and the networks of people who interact with these online communities can provide value to Army intelligence efforts. SM could facilitate the Military Decision Making Process by providing ongoing assessment of military actions from a local citizen perspective. Despite potential value, there are significant technological barriers to leveraging SM. SM collection and analysis are difficult in the dynamic SM environment and deception is a real concern. This paper introduces a credibility analysis approach and prototype fact-finding technology called the "Apollo Fact-finder" that mitigates the problem of inaccurate or falsified SM data. Apollo groups data into sets (or claims), corroborating specific observations, then iteratively assesses both claim and source credibility resulting in a ranking of claims by likelihood of occurrence. These credibility analysis approaches are discussed in the context of a conflict event, the Syrian civil war, and applied to tweets collected in the aftermath of the Syrian chemical weapons crisis.

    2016-09-01

    Full Text Available The effect of the presence of a con-specific in the temporal organization of food hoarding was studied in two varieties of Syrian hamster (Mesocricetus auratus: golden and long-haired. Four male hamsters of each variety were used. Their foraging behavior was observed during four individual and four shared trials in which animals were not competing for the same food source or territory. During individual trials, long-haired hamsters consumed food items directly from the food source, transporting and hoarding only remaining pieces. During shared trials, the long-haired variety hoarded food items before consumption, and increased the duration of hoarding trips, food handling in the storage, and cache size. Golden hamsters maintained the same temporal organization of hoarding behavior (i.e., hoarding food items before consumption throughout both individual and shared trials. However, the golden variety increased handling time at the food source and decreased the duration of hoarding trips, the latency of hoarding and storing size throughout the shared trials. In Syrian hamsters, the presence of a con-specific may signal high probability of food source depletion suggesting that social pressures over food availability might facilitate hoarding behavior. Further studies are required to evaluate cost-benefit balance of food hoarding and the role of cache pilferage in this species.

  6. Saudi Arabia plans future strategy

    International Nuclear Information System (INIS)

    The future strategy of Saudi Arabia with respect to its oil production capacity is discussed. A major uncertainty affecting planning is the prospect of an Iraqi return to the market as and when Saddam Hussein falls or he manages to comply fully with all the UN resolutions and sanctions are lifted. It is believed that Iraq could at very short notice be capable of exporting 2mb/d of crude rising to 2.5 mb/d within a few months. This is 10% of OPEC's physically traded crude. Also taken seriously are Baghdad's assertions that Iraq will have a production capacity of about 6mb/d by the year 2000. Saudi officials are concerned that OPEC is not ready to tackle the impact of an Iraqi return to the market at a time when some OPEC members are producing above quota anyway. The most likely outcome is thought to be that OPEC would simply raise their nominal production ceiling. Against this background, Saudi Arabia has embarked on the exploitation of the gigantic oil reserves of the Shaybah field. This development offers the kingdom an ability, on the one hand, to increase its earnings while remaining within its OPEC quota and, on the other hand, to increase output substantially should it ever appear that its best interests are served by not adhering to quotas.

  7. Overview of mutation breeding in Sudan

    International Nuclear Information System (INIS)

    Mutation breeding has effectively started about twenty years ago with the implementation of the first technical cooperation (TC) project of the IAEA in Sudan. This presentation highlights achievements and prospect of this collaboration. The first TC project (SUD 5/023) was confined to cotton and sugarcane while in the following projects (SUD 5/028 and SUD 5/030) other crops such as sesame, banana, tomato, groundnuts and cereals were included. The mutation program also benefited from the regional projects (RAF5/50 and RAF5/56). Plant breeders involved in mutation breeding increased from less than five in the first project to over 15 in the current one. A banana mutant cultivar (ALBEELY) was released in the year 2003. Albeely excelled the yield of the existing cultivars by 40% and has better crop stand and fruit quality. Albeely is becoming popular and widely preferred by farmers. A drought tolerant ground nut mutant (Barberton-B-30-3) and a number of promising mutants resistant for tomato yellow leaf curl virus (TYLCV) are being evaluated in multi-location trails in preparation for their commercial release. Cotton germplasm has been enrich with a number of useful mutants carrying resistance for bacterial blight and fusarium wilt disease in addition to mutants for weak fiber attachments and high ginning out turn and lint percentage. These mutants are being used in the breeding program and promising lines are under field evaluation for release. The mutation breeding program is strengthened by installing irradiator and establishing tissue culture and molecular laboratories. It is evident that the TC program of the IAEA has contributed significantly to the establishment and sustainability of mutation breeding and related biotechnologies in Sudan. The program is progressively expanding and a number of outstanding cultivars were released or in the pipeline. Intensive work is under way to generated production package for these mutants and set a demonstration plot program

  8. NORM waste management in the oil and gas industry. The Syrian experience

    International Nuclear Information System (INIS)

    Syrian experience with respect to naturally occurring radioactive materials (NORM) waste produced by the Syrian oil industry is described. Three main categories of NORM waste were identified. First, hard scales from decontamination of contaminated equipment and tubings which are considered to contain the highest levels of radium isotopes ( 226Ra, 228 Ra, 224 Ra); this type of waste being currently stored in standard barrels in a controlled area. Second, sludge wastes containing low levels of radium isotopes were found in large amounts in each Syrian oil field; plastic lined disposal pits were constructed in each area for temporary storage. However, disposal criteria for the above two categories of NORM waste are still under discussions. Third, soil contaminated with NORM as a result of uncontrolled disposal of production water was also considered as NORM waste. The Syrian criteria for disposal and clean up of this type of waste has been defined and approved by the Regulatory Office. (author)

    Sexual behavior is a natural reward for many rodent species, and it often includes chemosensory-directed components. Chemosensory stimuli themselves may also be rewarding. Conditioned place preference (CPP) is one paradigm frequently used to test the rewarding properties of a range of stimuli. Males and females of several rodent species show a CPP for sexual behavior, however, it is currently unknown whether sexual behavior can induce a CPP in male Syrian hamsters. As male Syrian hamsters are...

  16. Core configuration of the Syrian reduced enrichment fuel MNSR

    International Nuclear Information System (INIS)

    The possibility of substituting the actual HEU by a LEU or MEU in the Syrian MNSR is investigated through a pre-constructed 3-D detailed model of the reactor. Core configuration does not change if a reduced enrichment fuel (20% u-235, with the same percentages of impurity and eliminating aluminum) is used. The required density for the reactor to be critical in this case would be 7.29 g/cm2. If a specific fuel is used (20 w/o U235, 72 w/o U ), the reactor may not go critical at all. When a MEU fuel is used (45 w/o U235, 40 w/o U), the reactor will restore the same actual initial excess reactivity if 2 standard fuel rods are added to each fuel circle. (author)

    Full Text Available This paper aims at explaining the lessons learned from the chemical attacks that took place in 2013 in the Syrian military conflict, especially the sarin attacks on the Ghouta area of Damascus on August 21. Despite the limitations the UN Mission found while investigating the use of chemical weapons (CW in Syria, some interesting conclusions for the scientific and medical community can be obtained from its reports. These include the advantages of the Chemical Weapons Convention procedure for the investigation of alleged CW use, when compared with the United Nations mechanism for similar investigations, the difficulties of differential diagnosis based only on clinical signs and symptoms and the impact of secondary contamination when responding to a CW attack.

    1987-01-01

    Male Syrian golden hamsters chronically exposed to diethylstilbestrol (DES) develop renal adenocarcinomas with an incidence approaching 100%. The ability of the hamster kidney to bioactivate DES was assessed using hamster kidney slices. The male hamster renal cortex has a 2- to 5-fold greater capacity to irreversibly bind ({sup 3}H)DES as compared with female hamster renal cortex and with male hamster renal medulla. Incubation of the tissue under anaerobic conditions inhibited the metabolism and irreversible binding of ({sup 3}H)DES. Gel electrophoresis analysis of covalently modified proteins revealed several radioactive peaks indicating that specific adduct formation had occurred. The cytochrome P-450 inhibitors SKF 525-A, metyrapone, carbon monoxide, butylated hydroxytoluene, and dicumarol decreased the irreversible binding of ({sup 3}H)DES to renal cortical protein by 38 to 72%.

    1995-12-01

    Full Text Available Domestic factors played a significant role in Sudan's external debt crisis which emerged in the early 1980's. Personal rule and related political survival considerations undermined on-going economic adjustment programmes and prompted heavy external borrowing. Borrowing from abroad went unchecked because of the absence of an effective debt management system. It was also fuelled by economic corruption and the decline of cotton, Sudan's principal export crop. The absence of an effective debt management mechanism and economic corruption were a product of the lack of political and fiscal accountability in the context of personal rule.

  9. Licensing and inspection of industrial radiography in Sudan

    International Nuclear Information System (INIS)

    The use of radioisotopes in Sudan started in 1965 in the medical field, and gradually expanded in agriculture, animal research, hydrology and recently industry. During the last 4 years oil industry in Sudan became one of the biggest activity. Almost 11 foreign companies are involved in oil industry including exploration, establishment of refineries and construction of pipelines. Sudan's pipeline is the longest in Africa, about 1600 Km. The estimated number of radiation workers in these Companies are 100, some of them are locals. The country Regulatory Authority is Sudan Atomic Energy Commission (SAEC). The Commission provides personal monitoring services to all radiation workers in the country. Only about 20% of the radiation workers in these companies are under monitoring services. The total number of registered sources about 500. Number of sources used in the industrial applications of about 40% of the inventory. SAEC has difficulties in controlling the industrial radiography in the country. These difficulties can be summarized as follows: a. Difficulties in pertaining information provided by the Companies, which include: not all sources used by companies are licensed and registered; not all workers are under personal monitoring services; no notification system available by the companies to the regulatory authority in case of accidents; not enough information available by the companies to SAEC regarding the radiation work done by them (transparency). b. Poor communications with the companies. c. Resources constrains: Not enough resources for inspection missions (means of transportation). (author)

    International Nuclear Information System (INIS)

    The current situation of Peste des petits ruminants (PPR) in Sudan was investigated. A total of 1198 serum samples were collected from camels (392), sheep (500) and goats (306) at different areas in Sudan (Khartoum, Gezira, River Nile, Kordofan, White Nile, Gedarif, Kassala, Blue Nile, Tambool, Port Sudan, Halfa ElGadida). A total of 61 tissue samples were also collected from various PPR suspected outbreaks in sheep and goats in 2008. Collected sera were examined for PPR antibodies using cELISA. Collected tissue samples were tested for PPR antigen using IcELISA. Both tests were done according to the product manual of the kits manufacturer (CIRAD EMVT, Montpellier, France 2005), distributed by BDSL. A total of 336 sheep, 170 goat samples were found to be positive. Only one camel serum was positive. The PPR antigen was detected in 26 out of 61 samples. The PPR antibody and antigen detection results are summarized. The results showed that PPR exists in Sudan in different localities. The overall detected seroprevalence of PPR was 62.8%, which is higher than that previously reported (50%) in Sudan. Sheep were noticed to have higher percentage of seropositivity than goats (67.7 vs. 55.6%, respectively) in agreement with the results of Intisar et al. The highest seroprevalence of PPR (95%) was noticed in Kassala samples from Eastern Sudan followed by 83.3% in Blue Nile region (Eastern to South Sudan) and Gedarif (73.8%). PPR antibodies were found to be prevalent in sheep samples in Khartoum State (93.8%), then Gedarif (88.6%), Blue Nile (83.6%) and Gezira (73.6%). PPR antigen detection was carried out using IcELISA; the overall detected samples were 42.6% of 61 tested samples. Highest prevalence of the disease was noticed in River Nile, Gedarif and Kassala (100%) however only one sample was tested from each locality; Samples collected from Kordofan area showed 63.6% positivity while those of Gezira State were 27%.

    Full Text Available BACKGROUND: Despite historical evidence of blinding trachoma, there have been no widespread contemporary surveys of trachoma prevalence in the northern states of Sudan. We aimed to conduct district-level surveys in this vast region in order to map the extent of the problem and estimate the need for trachoma control interventions to eliminate blinding trachoma. METHODS AND FINDINGS: Separate, population based cross-sectional surveys were conducted in 88 localities (districts in 12 northern states of Sudan between 2006 and 2010. Two-stage cluster random sampling with probability proportional to size was used to select the sample. Trachoma grading was done using the WHO simplified grading system. Key prevalence indicators were trachomatous inflammation-follicular (TF in children aged 1-9 years and trachomatous trichiasis (TT in adults aged 15 years and above. The sample comprised 1,260 clusters from which 25,624 households were surveyed. A total of 106,697 participants (81.6% response rate were examined for trachoma signs. TF prevalence was above 10% in three districts and between 5% and 9% in 11 districts. TT prevalence among adults was above 1% in 20 districts (which included the three districts with TF prevalence >10%. The overall number of people with TT in the population was estimated to be 31,072 (lower and upper bounds = 26,125-36,955. CONCLUSION: Trachoma mapping is complete in the northern states of Sudan except for the Darfur States. The survey findings will facilitate programme planning and inform deployment of resources for elimination of trachoma from the northern states of Sudan by 2015, in accordance with the Sudan Federal Ministry of Health (FMOH objectives.

    Full Text Available The main objective of this research is to study the role of energy consumption in economic growth in Saudi Arabia over the period of 1971–2012 using the autoregressive distributed lag (ARDL cointegration procedure, and based on neoclassical growth, endogenous growth, and ecological-economics viewpoints. Our empirical results show the existence of a cointegrating relationship between the different variables investigated. In addition, all the inputs (conventional and non-conventional Granger cause economic growth in both the short and long runs. Our findings confirm the energy-led growth hypothesis in the case of Saudi Arabia. Hence, energy conservation policies may deteriorate economic growth in Saudi Arabia if they are not followed by measures that improve energy efficiency, energy saving technologies and encourage the investment and use of renewable energy sources such as solar and wind energies that can participate in the attenuation of climate changes.

  17. Early breeding and pregnancy diagnosis in Syrian awassi sheep yearlings

    International Nuclear Information System (INIS)

    Fifty-nine female yearlings of local Awassi sheep were randomly divided into 2 groups. Animals in group T (treated) were fitted with intravaginal sponges containing 60 mg of medroxyprogesterone acetate for 14 days followed by 400 IU of pregnant mare's serum gonadotrophin (PMSG) at sponge withdrawal, whereas group C (control) received no treatment. Oestrus rate was 92.7% and 11.2% for groups T and C, respectively. Lambing rate was 78% and 5.6% for groups T and C, respectively. Twinning rate was 31.3% in group T compared to zero in group C. Average birth weight for single born lams (4.7 ± 0.6 kg) was significantly (P > 0.05) higher than twin born lams (3.0 ± 0.5 kg) in group T. The average concentration of blood progesterone collected between days 17-19 after mating was 19.30 nmol/1 and the accuracy of early pregnancy diagnosis was 100%. It was concluded that, it is possible to induce synchronized oestrus, and to increase the twinning rate in Syrian Awassi sheep yearlings outside the breeding season, using intravaginal sponges and PMSG. In addition, early pregnancy diagnosis could be successfully determined in female Awassi sheep yearlings between days 17-19 after-mating. (author)

  18. Rift Valley fever virus infection in golden Syrian hamsters.

    Directory of Open Access Journals (Sweden)

    Dionna Scharton

    Full Text Available Rift Valley fever virus (RVFV is a formidable pathogen that causes severe disease and abortion in a variety of livestock species and a range of disease in humans that includes hemorrhagic fever, fulminant hepatitis, encephalitis and blindness. The natural transmission cycle involves mosquito vectors, but exposure can also occur through contact with infected fluids and tissues. The lack of approved antiviral therapies and vaccines for human use underlies the importance of small animal models for proof-of-concept efficacy studies. Several mouse and rat models of RVFV infection have been well characterized and provide useful systems for the study of certain aspects of pathogenesis, as well as antiviral drug and vaccine development. However, certain host-directed therapeutics may not act on mouse or rat pathways. Here, we describe the natural history of disease in golden Syrian hamsters challenged subcutaneously with the pathogenic ZH501 strain of RVFV. Peracute disease resulted in rapid lethality within 2 to 3 days of RVFV challenge. High titer viremia and substantial viral loads were observed in most tissues examined; however, histopathology and immunostaining for RVFV antigen were largely restricted to the liver. Acute hepatocellular necrosis associated with a strong presence of viral antigen in the hepatocytes indicates that fulminant hepatitis is the likely cause of mortality. Further studies to assess the susceptibility and disease progression following respiratory route exposure are warranted. The use of the hamsters to model RVFV infection is suitable for early stage antiviral drug and vaccine development studies.

    Anorexia and anxiety cause significant mortality and disability with female biases and frequent comorbidity after puberty, but the scarcity of suitable animal models impedes understanding of their biological underpinnings. It is reported here that in adult or weanling Syrian hamsters, relative to social housing (SH), social separation (SS) induced anorexia characterized as hypophagia, weight loss, reduced adiposity, and hypermetabolism. Following anorexia, SS increased reluctance to feed, and thigmotaxis, in anxiogenic environments. Importantly, anorexia and anxiety were induced post-puberty with female biases. SS also reduced hypothalamic corticotrophin-releasing factor mRNA and serum corticosteroid levels assessed by RT-PCR and RIA, respectively. Consistent with the view that sex differences in adrenal suppression contributed to female biases in anorexia and anxiety by disinhibiting neuroimmune activity, SS elevated hypothalamic interleukin-6 and toll-like receptor 4 mRNA levels. Although corticosteroids were highest during SH, they were within the physiological range and associated with juvenile-like growth of white adipose, bone, and skeletal muscle. These results suggest that hamsters exhibit plasticity in bioenergetic and emotional phenotypes across puberty without an increase in stress responsiveness. Thus, social separation of hamsters provides a model of sex differences in anorexia and anxiety during adulthood and their pathogeneses during adolescence.

    Nickel carbonyl was administered to groups of pregnant hamsters by inhalation on days 4, 5, 6, 7, or 8 of gestation. The dams were killed on day 15 of gestation, and the fetuses were examined for malformations. Exposure to Ni(CO)/sub 4/ on days 4 or 5 of gestation resulted in malformation in 5.5% and 5.8% of the progeny, respectively. Progeny included 9 fetuses with cystic lungs, 7 fetuses with exencephaly, 1 fetus with exencephaly plus fused rib and 1 fetus with anophthalmia plus cleft palate. Hemorrhages into serious cavities were found. In progeny of dams exposed to Ni(CO)/sub 4/ on days 6 or 7 of gestation, there was 1 fetus with fused ribs and there were 2 fetuses with hydronephrosis. In another experiment, pregnant hamsters were exposed to inhalation of Ni(CO)/sub 4/ on day 5 of gestation; these dams were permitted to deliver their litters and to nurse their pups. There was no significant difference in the average number of live pups in the Ni(CO)/sub 4/-exposed litters compared to control litters. Neonatal mortality was increased in Ni(CO)/sub 4/-exposed litters. This study demonstrates that Ni(CO)/sub 4/ is teratogenic and embryotoxic in Syrian hamsters.

All sectors of Syrian society have been included in this military conflict, not only social, but also ethnic. For example, the active role played in the war, Syrian Kurds, who were even able to declare an independent Kurdistan in the north of Syria. An important part of this article was the role of a terrorist organization ISIL in the Syrian war and ways of confronting it, which have a friendly country to Syria - Russia and Iran. For Syria, the Russian Federation, the Islamic Republic of Iran are longtime partners, who support each other for the past 25 years. Cooperation between the two began when the father of the current Syrian President Bashar al-Assad, Hafez al-Assad and dynamically developed before the conflict between the government and the opposition. Given the fact that the current position of Assad on the world stage is not strong enough, Russia and Iran as the main partners of the Syrian Republic, are trying to provide adequate assistance to the policy pursued by President Assad, considering that the legitimate elected president has the legitimate right to security citizens in their country, including the conduct of combat operations on the territory of the state. Thus, the main purpose of this article is to examine the causes of the conflict in Syria, as well as the analysis of Russia and Iran as a major strategic partner of the Syrian Republic. Relations between Russia, Syria and Iran, also have a special place in the article, as these countries have the most support of Syria and President B. Assad. Of course, to describe all the military conflict in Syria in one article is not possible, however, the author tried to present in detail the most basic aspects of the Syrian civil

    The progress of women in physics education in the last five years was surveyed in the six top universities in Sudan. The data reveal great increases in the number of females studying undergraduate physics. Most were studying experimental physics rather than theoretical physics, especially the laser and electronics fields. It appears undergraduate laboratory experiments are an important factor in attracting women to physics. Our survey found that girls are encouraged to study physics at the high school level. However, the data also showed that the fewer tendencies to study physics among the women after high school are due to the limited job opportunities and low income of teachers. Postgraduate physics study is handicapped by lack of institutions, financial constraints, and lack of qualified advisors. Improvement of education systems and new ways of teaching will have great influences on attracting women to physics in Sudan.

    From 2006 to 2012, the South Sudan Guinea Worm Eradication Program reduced new Guinea worm disease (dracunculiasis) cases by over 90%, despite substantial programmatic challenges. Program logistics have played a key role in program achievements to date. The program uses disease surveillance and program performance data and integrated technical-logistical staffing to maintain flexible and effective logistical support for active community-based surveillance and intervention delivery in thousands of remote communities. Lessons learned from logistical design and management can resonate across similar complex surveillance and public health intervention delivery programs, such as mass drug administration for the control of neglected tropical diseases and other disease eradication programs. Logistical challenges in various public health scenarios and the pivotal contribution of logistics to Guinea worm case reductions in South Sudan underscore the need for additional inquiry into the role of logistics in public health programming in low-income countries.

  15. Prevalence of Trypanosoma vivax in cattle in central Sudan

    International Nuclear Information System (INIS)

    The study was conducted to validate an antibody-detection ELISA test (Ab-ELISA) using pre-coated ELISA plates with crude antigen preparation of Trypanosoma vivax and to study the prevalence of T. vivax infection in central Sudan. A total of 704 blood samples were collected from cattle in central Sudan, a known endemic area of T. vivax infection. Additionally, 74 blood samples were collected from northern Sudan (Atbra town), an area presumed to be T. vivax-free. Sera were collected during the period September 1998 to May 1999 during three different seasons (summer, autumn and winter). Under the existing laboratory conditions, the test showed a clear distinction between different controls, i.e. strong positive control (C++), weak positive control (C+), negative control (C-) and the conjugate control (Cc). A percent positivity of 25% was taken as a cut-off value to determine the positivity or negativity of the test. The acceptable optical density range of strong positive control (C++) was 0.65-1.22. Lower and upper percent positivity limits for different controls were also determined. The study showed that T. vivax is endemic in central Sudan with 1.4% prevalence based on parasitological examination and 29.26% on Ab-ELISA. The infection rate was significantly higher during the autumn and winter than in summer. Young cattle showed significantly lower infection rates than adults as indicated by both the parasitological and the Ab-ELISA test. In relation to husbandry practice, migratory cattle showed significantly higher rates of prevalence than resident cattle. There was no significant difference in average packed red cell volume (PCV) values between ELISA positive and ELISA negative animals. Calves of less than one year of age showed significantly lower PCV values when belonging to migratory herds than to resident herds. (author)

  16. Career profile of dentists in Saudi Arabia

    International Nuclear Information System (INIS)

    The aims of the present survey were to determine whether differences existed between male and female dentists in Saudi Arabia in career development, positions occupied within their employment, and to analyze the effect of different variables on their career development in some of the provinces in Saudi Arabia. A self-conducted questionnaire was distributed among male and female dentists, general practitioners as well as specialists, working at several governmental hospitals in Saudi Arabia. The questionnaires consisted of 40 questions in the format of multiple choices and yes/no answer. Data were analyzed by gender with the significant difference level set at (P < 0.05). The response rate was 40.8% of which 51.9% were females and 48.1% males with 70% of them below 45 years of age. No significant difference was found between males and females in having higher education or additional degrees. The specialty that was highly reported among females was pedodontics and in males, orthodontics. Males were more likely to hold authorized administrative positions (63%), while females held administrative positions which were internally arranged by their departments (57%). Eighty-three percent of female respondents thought that there was favouritism towards males in appointment to administrative positions, while only 5.5% of male respondents reported that there was favouritism to females in occupying the same positions. There was no significant difference between male and female dentists in Saudi Arabia with respect to job opportunities, working hours and relationships with their colleagues. In addition, there is evidence of an intensifying determination of female dentists in Saudi Arabia, to pursue their chosen career while coping with the diverse demands of being a professional, a wife and mother.

    Full Text Available Abstract Background Breastfeeding is considered the ideal method of infant feeding for at least the first six months of life. This study aimed to compare breastfeeding intention between Syrian and Jordanian women and determine factors associated with breastfeeding intention among pregnant women in these two countries. Methods A cross-sectional design was used to collect data from1200 pregnant women aged 18 years and above (600 participants from each country. A self- administered questionnaire was used to collect data on socio-demographic characteristics and breastfeeding intention. Results Intention to breastfeed was reported by 77.2% of Syrian and 76.2% of Jordanian pregnant women. There was no significant difference in intention to breastfeed between Syrian women and Jordanian women. In both countries, women with a more positive attitude to breastfeeding, women with previous breastfeeding experience and women with supportive partners were more likely to intend to breastfeed. Syrian women with a monthly family income of more than US$200, younger than 25 and primiparous or having one child were more likely to report an intention to breastfeed their infants. Jordanian women with an education level of less than high school and not living with their family-in-law were more likely to intend to breastfeed. Conclusions In Syria and Jordan, a more positive attitude to breastfeeding, previous breastfeeding experience and presence of supportive husbands are associated with intention to breastfeed. These factors should be considered when planning programs designed to promote breastfeeding in these two countries.

  17. Peaceful nuclear energy to Saudi Arabia

    International Nuclear Information System (INIS)

    The argument for and against the application of peaceful nuclear energy in Saudi Arabia is discussed in terms of the country's industrial development and power requirement for electricity and desalination. The discussion leads to the conclusion that due to its large oil reserve, Saudi Arabia may tolerate a considerate approach to nuclear energy up to the year 2000. Beyond this date, nuclear energy should be used in order to achieve the desired industrial maturity in the country. The introduction of nuclear energy, however, will be faced with three constraints, namely man power availability, cooling water requirement, and the size of the electrical grid. The period 1980-2000 is thus most suitable for important preparation steps, among which are the adoption of regulatory provisions, establishment of nuclear facilities with necessary equipments, and staff training for regulatory, organizational, and technical activities. The paper outlines a scheme for the initiation steps and efforts to meet these requirements. (orig.)

  18. Solar Power Potential In Saudi Arabia

    F. R. Pazheri

    2014-09-01

    Full Text Available The expansion of power generation in Saudi Arabia is essential in order to meet the expected growth of its electricity demand. Due to the availability of high solar irradiation, vast rainless area and longtime sun light, Saudi Arabia is one of the most suitable countries to utilize solar energy resources in greater extend. Kingdom has planned to increase the production of solar power in order to meet a considerable share of country’s future energy demand. Numerous installation and research works are going on nowadays in the kingdom in order to attain its targets of solar power capacity in the coming years. Hence latest updates of country’s solar industry are essential for further research and R&D works in this field. Saudi Arabia’s current status and future possibility of solar industry are discussed in this paper.

  19. Core inflation indicators for Saudi Arabia

    Directory of Open Access Journals (Sweden)

    Alkhareif Ryadh M.

    2015-01-01

    Full Text Available This paper constructs and analyzes core inflation indicators for Saudi Arabia for the period of March 2012 to May 2014 using two alternative approaches: the exclusion method (ex food and housing/rent and the statistical method. The findings of the analysis suggest that the ex food and housing/ rent inflation is more volatile than the overall CPI inflation over the sample period. In contrast, the statistical core inflation is relatively more stable and less volatile. Moreover, the ex food and housing/rent inflation is only weakly correlated with headline inflation, whereas the statistical core inflation exhibits a stronger correlation. This combination of lower volatility and higher correlation with headline inflation makes the statistical method a much better choice for policymakers. From a monetary policy standpoint, using a bundle of core inflation measures, including both properly constructed exclusion and statistical methods, is more desirable, especially when variation across measures is widespread, as is the case in Saudi Arabia.

    2013-04-01

    Full Text Available A review of the literature on successful implementation of ERP reveals that there are many case studies undertaken by researches, but very few have empirically examined the success factors of ERP implementation. While most of those empirical studies were undertaken in Western countries, very few had examined the implementations in Middle Eastern countries and none in Saudi Arabia. Factors and challenges of ERP implementation in developing countries differ from those of Western countries. Hence a gap in the literature that examines Middle Eastern countries exists. This study is motivated to fill such gap by going beyond case study and boundaries of Western counties to empirically examine the determinants of successful ERP implementation in Saudi Arabia. The main purpose of this study is to examine the influence of some critical factors on successful implementation of ERP.

    Full Text Available The conflict in Syria between the government of Bashar al-Assad and various other forces, which started in the spring of 2011, continues to cause displacement within the country and across the region. By the end of 2014, an estimated 7.6 million people were internally displaced and 3.7 million Syrians had fled the country since the conflict began (OCHA 2014; UNHCR 2015a. The refugee situation caused by the Syrian conflict is dire, and it has placed enormous strain on neighboring countries. Lebanon, Jordan, Iraq, Egypt, and Turkey host massive numbers of Syrian refugees, and Syrians have been seeking protection beyond these countries in increasing numbers since 2011.This paper looks at the burdens and costs of the Syrian refugee crisis and considers how they have, or have not, been shared by the international community at large, and in particular by Germany, Sweden, the United Kingdom, and the United States. It also considers to what degree Syrians have been able to find protection in states outside the region. Germany and Sweden, by the end of 2014, had provided protection to the largest number of Syrian refugees outside the region. Although Germany, Sweden, the United Kingdom, and the United States differ in the level of protection provided to Syrians, all four states have increased protection to Syrians via resettlement and asylum (and in the case of the US temporary protected status since 2012. Despite this, the degree of protection provided by the four states is modest in relation to that provided by neighboring countries to Syria, and far more could be done. This paper also argues that the international community as a whole has not sufficiently contributed toward alleviating the burden caused by the Syrian refugee influx, in terms of both financial assistance and refugee resettlement.The paper puts forward two general recommendations to reduce the strain on neighboring countries: increase the level of burden sharing by the international

    The civil war in Syria has culminated into major refugee crises in its neighboring countries. By the end of 2013 more than half a million people were seeking shelter in cities and refugee camps in Turkey. We analyze how the Syrian refugee influx in Turkey has affected food and housing prices, employment rates and internal migration patterns in regions of Turkey where refugees are being accommodated. Refugee camps are geographically concentrated near the Syrian border, which enables us to empl...

    Full Text Available Surveying is an important part of any archaeological research. In this paper we focus on the archaeological research in north Sudan (6th Nile cataract and the surveying methods applicable under the local conditions. Surveying in the Third World countries is affected by the political situation (limited import of surveying tools, local conditions (lack of fixed points, GNSS correction signal, inaccessible basemaps and fixed point network. This article describes the methods and results obtained during the three archaeological seasons (2011-2014. The classical surveying methods were combined with KAP (Kite Aerial Photography to obtain the desired results in form of archaeological maps, detailed orthophoto images and other analyses results.

    2014-01-01

    The export of organic fruit and vegetables to the European Union might offer a great opportunity for Syrian farmers and exporters. Yet, the organic sector in Syria is comparatively young and only a very small area of fresh fruit and vegetables (FFV) is organically managed. To date, little is known about Syrian farmers’ attitudes towards organic fruit and vegetable production. Therefore, the aim of this study was to explore the intentions and attitudes of Syrian farmers of FFV towards organic ...

    2004-11-01

    Full Text Available In a cross sectional survey conducted during the period June 2001 to July 2002, the geographical distribution of ticks on cattle in the Sudan was determined. Seventeen locations were surveyed from Northern, Central, Eastern, Western, Blue Nile and White Nile Provinces. Total body collections of ticks were made from 20 cattle at each location. Four tick genera and 11 species were identified. The tick species collected included Amblyomma lepidum, Amblyomma variegatum, Boophilus decoloratus, Hyalomma anatolicum anatolicum, Hyalomma dromedarii, Hyalomma impeltatum, Hyalomma marginatum rufipes, Hyalomma truncatum, Rhipicephalus evertsi evertsi, Rhipicephalus sanguineus group and Rhipicephalus simus simus. Major ecological changes have occurred due to extensive animal movement, deforestation, desertification and establishment of large mechanized agricultural schemes. These factors have certainly affected the distribution of ticks and tick-borne diseases in the Sudan. The absence of A. variegatum and A. lepidum in northern Sudan was not surprising, since these tick species are known to survive in humid areas and not in the desert and semi-desert areas of northern Sudan. The absence of B. annulatus in northern and central Sudan is in accordance with the finding that this tick species is restricted to the southern parts of the central Sudan. The presence of H. anatolicum anatolicum in Um Benin in relatively high abundance is an interesting finding. The present finding may indicate that the southern limit of this species has changed and moved southwards to latitude 13o N. It is concluded that major changes in tick distribution have taken place in the Sudan

    Full Text Available In the last two decades, the chemical and biological contaminants in livestock and livestock products worldwide have been considered as one of the causes that threatens life of both man and animals. In Sudan very little work has been done in this field. This study was carried out to detect Oxytetracycline (OTC residues in sheep liver and muscle samples in Khartoum State, Sudan. A total of 150 samples comprising of liver (n=75 and muscle (n=75 of sheep were collected from three different localities in Khartoum State during the period from March to September 2013. The OTC residues were detected using high performance liquid chromatography (HPLC and one plate test (OPT. The results of HPLC showed that the level of OTC residues in liver samples above maximum residue limit (MRL was 4% (n=3/75 and under MRL was 96%. Regard to muscle samples, the level of OTC residues above MRL was 60.3% (n=35/58, whereas, under MRL was 39.7%. Using OPT, 14.7% (n=11/75 and 6.7% (n=5/75 of liver and muscle samples showed inhibition zone, respectively. It is concluded that OTC residues are detected in sheep liver and muscle sample with different levels in Khartoum state. Further investigation on level of OTC residues in other farm animals and other organs throughout the country is recommended. [J Adv Vet Anim Res 2015; 2(3.000: 321-325

  12. Developing a comprehensive and sustainable integration strategy for Syrian refugee children in Denmark

    2016-01-01

    A 2013 United Nations Refugee Agency report entitled The Future of Syria stated that two million Syrian children have been forced into exile as a result of the persistent civil war: “The world must act to save a generation of traumatized, isolated and suffering Syrian children from catastrophe....... If we do not move quickly, this generation of innocents will become lasting casualties of an appalling war”. Such a statement has found ritual credence in images of refugees braving (and perishing) in the tumultuous waters of the Mediterranean in search of a safe haven. But more recently, the possible...... abduction of 10,000 unaccompanied refugee children by organised trafficking syndicates has confirmed that children are indeed the most vulnerable when in exile.

    Smetana, Judith G; Ahmad, Ikhlas; Wray-Lake, Laura

    2015-01-01

    This study examined intra- and interindividual variations in parental legitimacy beliefs in a sample of 883 Arab refugee adolescents (M(age) = 15.01 years, SD = 1.60), 277 Iraqis, 275 Syrians, and 331 Palestinians in Amman, Jordan. Confirmatory factor analyses showed distinct latent factors for moral-conventional, prudential, and personal legitimacy items. Older adolescents rated legitimacy lower for personal issues, but higher for prudential issues. Beliefs were associated with socioeconomic status (fathers' education, family size), particularly for personal issues, but were more pervasively associated with displacement-related experiences. Greater war trauma was associated with less prudential legitimacy for all youth and more authority legitimacy over moral-conventional issues for Syrian youth. Greater hopefulness was associated with more authority legitimacy over all but personal issues.

  14. Recovery of uranium from the Syrian phosphate by solid-liquid method using alkaline solutions

    International Nuclear Information System (INIS)

    Uranium concentrations were analyzed in the Syrian phosphate deposits. Mean concentrations were found between 50 and 110 ppm. As a consequence, an average phosphate dressing of 22 kg/ha phosphate would charge the soil with 5-20 g/ha uranium when added as a mineral fertilizer. Fine grinding phosphate produced at the Syrian mines was used for uranium recovery by carbonate leaching. The formation of the soluble uranyl tricarbonate anion UO2(CO3)34- permits use of alkali solutions of sodium carbonate and sodium bicarbonate salts for the nearly selective dissolution of uranium from phosphate. Separation of iron, aluminum, titanium, etc., from the uranium during leaching was carried out. Formation of some small amounts of molybdates, vanadates, phosphates, aluminates, and some complexes metal was investigated. This process could be used before the manufacture of TSP fertilizer, and the final products would contain smaller uranium quantities. (author)

  15. The Middle East respiratory syndrome coronavirus (MERS-CoV does not replicate in Syrian hamsters.

    Directory of Open Access Journals (Sweden)

    Emmie de Wit

    Full Text Available In 2012 a novel coronavirus, MERS-CoV, associated with severe respiratory disease emerged in the Arabian Peninsula. To date, 55 human cases have been reported, including 31 fatal cases. Several of the cases were likely a result of human-to-human transmission. The emergence of this novel coronavirus prompts the need for a small animal model to study the pathogenesis of this virus and to test the efficacy of potential intervention strategies. In this study we explored the use of Syrian hamsters as a small animal disease model, using intratracheal inoculation and inoculation via aerosol. Clinical signs of disease, virus replication, histological lesions, cytokine upregulation nor seroconversion were observed in any of the inoculated animals, indicating that MERS-CoV does not replicate in Syrian hamsters.

  16. Design calculation of a horizontal thermal neutronic beam for neutron radiography at the Syrian MNSR

    International Nuclear Information System (INIS)

    The computer code MCNP4C and the ENDF/B-V cross-section library were used to design calculation of a horizontal thermal beam for neutron radiography (NR) at Syrian MNSR and to evaluate the safety of the reactor after installation of the NR facility (NRF). Thermal, epithermal and fast neutron energy ranges were selected as 10.0 keV, respectively. To produce a good neutron beam in terms of intensity and quality, bismuth (Bi) and silicon (Si) were used as photon and neutron filters, respectively. The ratio of L/D of the NRF ranges between 90 and 125. The thermal neutron flux at the beam exit plane can be varied from 1.836 × 105 to 3.057 × 105 n/cm2 s. If such thermal neutron beam would be built into the Syrian MNSR, many scientific applications of the NR would be available. (author)

    Full Text Available The relationships between breadmaking quality, kernel properties (physical and chemical, and dough rheology were investigated using flours from six genotypes of Syrian wheat lines, comprising both commercially grown cultivars and advanced breeding lines. Genotypes were grown in 2008/2009 season in irrigated plots in the Eastern part of Syria. Grain samples were evaluated for vitreousness, test weight, 1000-kernel weight and then milled and tested for protein content, ash, and water content. Dough rheology of the samples was studied by the determination of the mixing time, stability, weakness, resistance and the extensibility of the dough. Loaf baking quality was evaluated by the measurement of the specific weight, resilience and firmness in addition to the sensory analysis. A comparative study between the six Syrian wheat genotypes and two English flour samples was conducted. Significant differences were observed among Syrian genotypes in vitreousness (69.3%–95.0%, 1000-kernel weight (35.2–46.9 g and the test weight (82.2–88.0 kg/hL. All samples exhibited high falling numbers (346 to 417 s for the Syrian samples and 285 and 305 s for the English flours. A significant positive correlation was exhibited between the protein content of the flour and its absorption of water (r = 0.84 **, as well as with the vitreousness of the kernel (r = 0.54 *. Protein content was also correlated with dough stability (r = 0.86 **, extensibility (r = 0.8 **, and negatively correlated with dough weakness (r = −0.69 **. Bread firmness and dough weakness were positively correlated (r = 0.66 **. Sensory analysis indicated Doumah-2 was the best appreciated whilst Doumah 40765 and 46055 were the least appreciated which may suggest their suitability for biscuit preparation rather than bread making.

  4. Refugees of the Syrian Civil War: Impact on Reemerging Infections, Health Services, and Biosecurity in Turkey.

    2016-01-01

    After the Arab Spring uprising, Syria descended into a civil war in 2011. By March 2016, the United Nations reported that 13.5 million Syrians required humanitarian assistance, including 6.6 million internally displaced persons and more than 4.8 million refugees outside of Syria. Turkey is currently hosting the largest number of Syrian refugees-more than 2.7 million. A limited number of refugees are living in camps settled around the border, and others are spread throughout Turkey. This explosive and unexpected increase in the Syrian population in Turkey has had several negative impacts on health and social determinants. The overload of healthcare facilities has led to shortages in childhood immunization programs, drugs, and access to clean water and food supplies. According to Ministry of Health data, more than 7.5 million Syrians were examined at outpatient clinics, and 299,240 were hospitalized; most of those hospitalized were injured and wounded victims who require and have been occupying intensive care units. The refugees generally live in crowded and unsanitary conditions, which may lead to the spread of respiratory, skin, gastrointestinal, and genital system infections. Currently, measles, poliomyelitis, leishmaniasis, and multidrug-resistant tuberculosis are the reemerging infections being most frequently recorded. Multidrug-resistant gram-negative bacterial infections seem to be an increasing problem in gunshot or surgical wounds. Hepatitis A, malaria, and varicella have been seen with a high incidence among the refugees. There are many problems waiting to be resolved for health and living standards in Turkey. PMID:27362427

    Since the uprising in Syria in March 2011, over 4.3 million Syrians have fled to neighboring countries. Over a million have sought refuge in Lebanon, constituting almost a quarter of the Lebanese population and becoming the largest refugee population per capita in the world. With inequitable health coverage being a longstanding problem in Lebanon, Syrian refugee women's health, and specifically their sexual and reproductive health, is disproportionately affected. An increase in gender-based violence and early marriage, a lack of access to emergency obstetric care, limited access to contraception, forced cesarean sections, and high cost of healthcare services, all contribute to poor sexual and reproductive health. In this commentary, we conceptualize violence against Syrian refugee women using the ecological model, exploring the intersections of discrimination based on ethnicity, gender, and socioeconomic status, while critiquing interventions that focus solely on the intrapersonal level and ignore the role of microsystemic, exosystemic, and macrosystemic factors of negative influence. These social determinants of health supersede the individual realm of health behavior, and hinder women in taking decisions about their sexual and reproductive health. PMID:27578336

    Wind data for 20 locations in Saudi Arabia have been analysed. Monthly and annual mean wind speeds and wind powers have been determined. The latter range from 2.5 to 4.4 m s/sup -1/, and from 21.8 to 77.7 W m/sup -2/, respectively. Specific outputs from two hypothetical aerogenerators with rated wind speeds of 5 and 7 m s/sup -1/ have been estimated. Examples of monthly mean wind speed and wind power temporal variations are given. Results suggest that wind power would be more profitably used for local small-scale applications. (author).

    Full Text Available This study is about the revolution of information and communication technology (ICT. It deals with the evolution of banking technology (BT, electronic banking (e-banking and mobile banking (m-banking in Sudan. It intends to explore the practice of m-banking in Sudan. The focus is on the availability of adequate infrastructure and on the challenges and risks that face m-banking services in Sudan. The findings showed that although mbanking is believed to be essential, still the services provided are at an infant stage. It is also found that concerned parties are not fully cooperating. This raises risks and constitutes challenges that hinder full utilization of m-banking in Sudan. Based on these results, the main recommendation of the researchers was that regulatory policies should be stated clearly to ensure full collaboration between all concerned parties. This is to support bank managers and decision makers in formulating their strategic plans to deliver competitive services.

  3. Investigation of natural radioactivity levels in water around Kadugli, Sudan

    International Nuclear Information System (INIS)

    Surface water from Miri Lake and groundwater from around Kadugli (West-Central Sudan) obtained by means of hand-pumps was analysed for 238U, 226Ra, 222Rn, and 232Th activity concentrations. The surface water showed very low levels of radionuclide concentrations: -1 for 238U, 226Ra, 222Rn, and 232Th, respectively. Groundwater revealed a significant amount of natural radioactivity (16.1-1720, 7.7-14.3, 3000-139,000, -1) respectively. The overall annual effective dose was below the WHO reference dose level of 0.1 mSv yr-1 except in one groundwater sample with an associated dose of 0.7 mSv yr-1

    Four wood species, indigenous Acacia seyal (talh) and exotic fast-growing Conocarpus lancifolius (damas), Eucalyptus microtheca (kafur) and Prosopis chilensis (mesquite) grown in Sudan, were assessed and compared as raw materials for charcoal making. The effects of production method (traditional earth mound and improved metal kiln) and the physical and chemical properties of the wood and bark on the yield and quality of charcoal produced were assessed. Regression analyses of wood properties and heat value data indicated high negative correlations of the wood heat value with halocellulose and ash, and high positive correlations with wood density, lignin, and alcohol-benzene and hot-water solubles. Carbonization with the Tropical Products Institute metal kiln produced higher yields (33%) than the traditional earth mound (27%), although the difference in energy transformation yields was found to be insignificant both between appliances and species.

    This study was performed in Radiation and Isotopes Center of Khartoum (RICK) and National Cancer Institute (NCI) University of Gazeria. It focused on cancer patients who were treated by radiation therapy in the period between 2008 and 2009. The study investigator the risk and causative factors and geographical distribution over the sudan states and the relationship of incidence with some patient's customs and dietary habits. This study summarizes recent scientific evidence of environmental and occupational links to nearly 30 types of cancer. the discussion of each cancer type is introduced by highlights of trends in incidence. The study considers additional indication that involuntary exposures are linked to cancers, such as patterns observed in different geographic areas and among different population patterns of cancer in children. The purpose of this study is to review scientific evidence, particular y epidemiologic evidence. regarding the contribution of environmental and occupational exposures to the overall cancer incidence in the Sudan. The study discussed that the widespread exposures from air and water pollution, the work environment, exposure resulting form personal habits such as smoking and drinking and the diet are major contributors to cancer in human. In the past three decades, there have been several efforts to estimate the proportion of caner due to these involuntary exposure, starting with an ambitious effort by different scientists. This study provided and alternative interpretation of the evidence of cancer incidence to particular factors. We conclude the study by recommending the significance of giving environmental and occupational links to cancer serious consideration by individuals and institutions concerned with cancer prevention, particularly those involved in research and education.

    Global warming is occurring at an alarming rate and predictions are that air temperature (T a) will continue to increase during this century. Increases in T a as a result of unabated production of greenhouse gases in our atmosphere pose a threat to the distribution and abundance of wildlife populations worldwide. Although all the animals worldwide will likely be affected by global warming, diurnal animals in the deserts will be particularly threatened in the future because T as are already high, and animals have limited access to water. It is expected that Saudi Arabia will experience a 3-5 °C in T a over the next century. For predicting the consequences of global warming for animals, it is important to understand how individual species will respond to higher air temperatures. We think that populations will not have sufficient time to make evolutionary adjustments to higher T a, and therefore they will be forced to alter their distribution patterns, or make phenotypic adjustments in their ability to cope with high T a. This report examines how increases in T a might affect body temperature (T b) in the animals of arid regions. We chose three taxonomic groups, mammals, birds, and reptiles (Arabian oryx, Arabian spiny-tailed lizard, vultures, and hoopoe larks) from Saudi Arabia, an area in which T a often reaches 45 °C during midday in summer. When T a exceeds T b, animals must resort to behavioral and physiological methods to control their T b; failure to do so results in death. The observations of this study show that in many cases T b is already close to the upper lethal limit of around 47° C in these species and therefore allowing their T b to increase as T a increases are not an option. We conclude that global warming will have a detrimental impact on a wide range of desert animals, but in reality we know little about the ability of most animals to cope with change in T a. The data presented should serve as base-line information on T b of animals in the

    Full Text Available Achieving and maintaining a stable nursing workforce is an important issue for the well-being of the rapidly growing population of Saudi Arabia. However, high turnover of expatriate staff and low recruitment of Saudi nationals have led to a serious staff shortage in the professions, particularly of well-qualified and experienced nurses. Nursing leaders need to work to improve the image of nurses and facilitate the recruitment of women into the nursing profession. Reduced working hours and part-time contracts with increased salaries and benefits could attract more young women to the profession, as might the provision of facilities such as private transportation and on-site childcare. Furthermore, establishing a national association for nurses would advance the nursing profession and help to ensure that all nurses undertake fully comprehensive training before entering the workforce.

It must be added  that while documentary  evidence and partial studies on  this period  exist,  it turns out that documentation on the contemporary period  is scarce. This article also  is concerned with describing the evolution  of certain striking  aspects of the close  relation  between  the pilgrimage to Mecca  and Indonesian migrants  looking  for work.  We need to consider  the methods  of hiring  labor,  the networks  involved  in recruiting it, the organization  of travel,  as well as the increasing indebtedness  of the migrants  through  intermediaries  who, more and more professionally, arrange  these attempts  to live abroad, prompted in many cases by the same desire  for wealth.Copyright (c 2014 by SDI.

    2000-01-01

    Full Text Available Glomerulonephritis (GN is one of the leading causes of end-stage renal disease. A good understanding of its pattern and prevalence as well as exploration of effective therapeutic strategies for protecting the glomerulus, would have tremendous impact on public health. In the Kingdom of Saudi Arabia (KSA, focal and segmental glomerulo sclerosis (FSGS is the commonest type of primary glomerular diseases (PGD encountered in clinical practice. Its prevalence varies from less than 4% in Gizan, in the southern part of KSA, to approximately 35% in Riyadh, central Saudi Arabia. In our experience, the nephrotic syndrome was the commonest mode of presentation of FSGS. Response to corticosteroid therapy is generally poor and the mortality rate is high. Mesangioproliferative GN is the second most common GN constituting up to 25% of PGD in our experience. Other researchers from different parts of the Kingdom, however, have given prevalence rates ranging from 8 to 57.1%. The reported prevalence of Immunoglobulin-A nephropathy (IgAN in KSA ranges from 5.8% to 13.6%. It is more common in the elderly, and men are affected more often than women. In contrast to KSA, IgAN is the commonest PGD in Japan, China, Hong Kong, Singapore and Taiwan. Membranous GN (MGN is less common in KSA than encountered elsewhere, the prevalence ranging from 3.9 to 21.8%. Nephropathy secondary to systemic diseases are also common in KSA. Lupus nephritis (LN accounted for 48.5% of secondary glomerular diseases (SGD with the combination of WHO classes III and IV (aggressive types of LN accounting for 56% of all patients. LN is another disease where differences in racial susceptibility may account for the uneven distribution. Post-streptococcal GN seems to be declining in frequency in KSA, the reported prevalence ranging from 2.7% to 2.9%.

    Sudan azo dyes are banned for food usage in most countries, but they are illegally used to maintain or enhance the color of food products due to low cost, bright staining, and wide availability of the dyes. In this report, we examined the toxic effects of these azo dyes and their potential reduction metabolites on 11 prevalent human intestinal bacterial strains. Among the tested bacteria, cell growth of 2, 3, 5, 5, and 1 strains was inhibited by Sudan I, II, III, IV, and Para Red, respectively. At the tested concentration of 100 μM, Sudan I and II inhibited growth of Clostridium perfringens and Lactobacillus rhamnosus with decrease of growth rates from 14 to 47%. Sudan II also affected growth of Enterococcus faecalis. Growth of Bifidobacterium catenulatum, C. perfringens, E. faecalis, Escherichia coli, and Peptostreptococcus magnus was affected by Sudan III and IV with decrease in growth rates from 11 to 67%. C. perfringens was the only strain in which growth was affected by Para Red with 47 and 26% growth decreases at 6 and 10 h, respectively. 1-Amino-2-naphthol, a common metabolite of the dyes, was capable of inhibiting growth of most of the tested bacteria with inhibition rates from 8 to 46%. However, the other metabolites of the dyes had no effect on growth of the bacterial strains. The dyes and their metabolites had less effect on cell viability than on cell growth of the tested bacterial strains. Clostridium indolis and Clostridium ramosum were the only two strains with about a 10 % decrease in cell viability in the presence of Sudan azo dyes. The present results suggested that Sudan azo dyes and their metabolites potentially affect the human intestinal bacterial ecology by selectively inhibiting some bacterial species, which may have an adverse effect on human health.

    Full Text Available There is no data on the prevalence of overweight and obesity in young Syrian boys. Therefore, the present study aimed to provide baseline and reference data on the prevalence of overweight and obesity among young Syrian boys using skin-fold thickness measurements and deuterium dilution (DD as a reference method. The sample of 2470 healthy Syrian 18- to 19-year-old boys were enrolled in this study. SFTs were measured at the biceps (B, triceps (T, subscapular (SI and suprailiac locations (SS were done and validated using the DD technique as a reference method. Receiver operating characteristics (ROC curve was drawn to determine appropriate cut-off points of the Σ2 limb SFT (T+B, Σ2 trunk SFT (SI+SS, Σ4 SFT (T+B+SI+SS and Log Σ4 SFT for defining overweight and obesity. The overall prevalence of overweight and obesity in young Syrian boys, based on biceps SFT, triceps SFT, subscapular SFT, suprailiac SFT, Σ2 limb SFT, Σ2 trunk SFT, Σ4 SFT, logarithm Σ4 SFT, and DDT were 35.3%, 32%, 31.6%, 14.8%, 32.9%, 26.6%, 28.1%, 24.1%, 46.5%, respectively. Strongly positive correlation was found between SFT and total body fat in adolescents. For diagnosing overweight on the basis of Σ2 limb SFT, Σ2 trunk SFT, Σ4 SFT and logarithm Σ4 SFT, we propose the following cut-off points: 17.25 mm, 23.50 mm, 39.25 mm and 1.60, respectively. To predict obesity, Σ2 limb SFT, Σ2 trunk SFT, Σ4 SFT and logarithm Σ4 SFT threshold were increased to 23.25 mm, 32.50 mm, 55.25 and 1.75, respectively. Basing on SFT clearly leads to underestimates of the prevalence of weight problems among young boys. SFT measurement screen missed 11.2 to 31.7% of overall overweight and obesity cases.

    Social media introduce pivotal changes to communication between individuals, organizations and communities. A clear example of the power of social media is the spread of the revolutionary outbreaks in the Arabic countries during 2011, where people used Facebook, YouTube and Skype to communicate, organise meetings and protest actions. Here I report how Doctor-Activists use these social media as an alarm system for 'war disease' outbreaks in the Syrian Spring. Social media are used as an alarm system to attract the attention of international organizations, which should assume their responsibilities and play their part in controlling the outbreak of such war diseases.

  9. Human African trypanosomiasis in South Sudan: how can we prevent a new epidemic?

    Directory of Open Access Journals (Sweden)

    José A Ruiz-Postigo

    Full Text Available Human African trypanosomiasis (HAT has been a major public health problem in South Sudan for the last century. Recurrent outbreaks with a repetitive pattern of responding-scaling down activities have been observed. Control measures for outbreak response were reduced when the prevalence decreased and/or socio-political crisis erupted, leading to a new increase in the number of cases. This paper aims to raise international awareness of the threat of another outbreak of sleeping sickness in South Sudan. It is a review of the available data, interventions over time, and current reports on the status of HAT in South Sudan. Since 2006, control interventions and treatments providing services for sleeping sickness have been reduced. Access to HAT diagnosis and treatment has been considerably diminished. The current status of control activities for HAT in South Sudan could lead to a new outbreak of the disease unless 1 the remaining competent personnel are used to train younger staff to resume surveillance and treatment in the centers where HAT activities have stopped, and 2 control of HAT continues to be given priority even when the number of cases has been substantially reduced. Failure to implement an effective and sustainable system for HAT control and surveillance will increase the risk of a new epidemic. That would cause considerable suffering for the affected population and would be an impediment to the socioeconomic development of South Sudan.

    Sudan dyes are a family of lipophilic azo dyes, extensively used in industrial and scientific applications but banned for use as food colorants due to their carcinogenicity. Due to the continuing illicit use of Sudan dyes as food colorants their determination in different food matrices--especially in different chilli and tomato sauces and related products--has during the recent years received increasing attention all over the world. This paper critically reviews the published determination methods of Sudan I-IV dyes. LC-UV-vis and LC-MS are the dominating methods for analysis of Sudan I-IV dyes. Sudan dyes are usually found in food at mg kg(-1) levels at which it may be necessary to use a preconcentration step in order to attain the desired detection limits. Liquid-solid extraction is the dominating sample preparation procedure. In recent years it has been supplemented by ultrasonic-assisted extraction and pressurized liquid extraction. Various solid phase extraction types have been used for sample cleanup. The large majority of works use conventional C18 columns and conventional LC eluents. Traditionally the UV-vis absorbance detection has been the most frequently used. In the recent years MS detection is applied more and more often as it offers more reliable identification possibilities.

  11. Conflicts in the Horn of Africa and their Consequences on Sudan's Stability and Security

    1995-06-01

    Full Text Available Armed conflicts in the Horn of Africa have been raging in that region for the last forty years with tragic consequences for human life and for economic advancement. These conflicts have three different, but overlapping dimensions: the intrastate, the interstate, and the global levels. The conflicts are of a decided relevance for the Sudan, and particularly to the rebellion in the southern Sudan. The lack of security and stability in southern Sudan forced hundreds of thousand southerners into neighbouring countries, especially Ethiopia and Uganda. Likewise, the Sudan hosted hundreds of thousands Eritreans, Ethiopians, and Ugandans caught in the crossfire of their national conflicts. This development not only created a heavy economic burden on these relatively poor and economically underdeveloped communities, but led to strained political relations among governments. The Sudan has deep-seated security concerns emanating from the tragic developments in that part of the world. It is argued that one practical step to defuse the situation is to look for political solutions for essentially political problems. The next step that follows logically from the first step is to establish economic cooperation arrangements with a view to creating a future economic community in that African region.

    Saffron, the dried red stigmas of Crocus sativus L., is considered as one of the most expensive spices worldwide, and as such, it is prone to adulteration. This study introduces an NMR-based approach to identify and determine the adulteration of saffron with Sudan I-IV dyes. A complete (1)H and (13)C resonance assignment for Sudan I-IV, achieved by two-dimensional homonuclear and heteronuclear NMR experiments, is reported for the first time. Specific different proton signals for the identification of each Sudan dye in adulterated saffron can be utilised for quantitative (1)H NMR (qHNMR), a well-established method for quantitative analysis. The quantification of Sudan III, as a paradigm, was performed in varying levels (0.14-7.1g/kg) by considering the NMR signal occurring at 8.064ppm. The high linearity, accuracy and rapidity of investigation enable high resolution (1)H NMR spectroscopy to be used for evaluation of saffron adulteration with Sudan dyes.

    Full Text Available Abstract The global malaria situation, especially in Africa, and the problems frequently encountered in chemical control of vectors such as insecticide resistance, emphasize the urgency of research, development and implementation of new vector control technologies that are applicable at regional and local levels. The successful application of the sterile insect technique (SIT for the control of the New World screwworm Cochliomyia hominivorax and several species of fruit flies has given impetus to the use of this method for suppression or elimination of malaria vectors in some areas of Africa including Northern State of Sudan. The research and development phase of the Northern State feasibility study has been started. Sudanese stakeholders are working side-by-side with the International Atomic Energy Agency in the activities of this important phase. Several ethical, legal and social issues associated with this approach arose during this phase of the project. They need to be seriously considered and handled with care. In this paper, these issues are described, and the current and proposed activities to overcome potential hurdles to ensure success of the project are listed.

    Full Text Available Jir hur is a traditional fermented food of the Fur tribe of western Sudan prepared from bulrush millet (Penisitum typhoidism. The microbiological changes during the fermentation stages were monitored. LAB count increased from 4.48 in raw millet to 7.19 log/cfug in jir hur and yeast count increased from 3.77 to 7.55 log/cfug, respectively with significant changes in pH from 6.66 in raw millet to 3.68 in jir hur. The fermentation of millet into jir was a homo-lactic acid fermentation that involved a complex microbial succession between LAB and yeast. LAB was the predominant microorganisms during the first fermentation with significant increase in yeast counts. Pediococcus halophilus, Pediococcus inopinatus and Pediococcus urinaeequi were the dominant lactic acid bacteria species at all times with the association of Lactobacillus acidophilus and Lactobacillus jensenii at the second fermentation. The yeast species Schizosaccharomyces pombe, Saccharomycods sinensis and Trichosporon adeninovorans were followed in succession during jir fermentation stages.

  20. Studies on simple goitre epidemiology and aetiology in Sudan

    International Nuclear Information System (INIS)

    The objectives of this study were to map the prevalence of goiter in Sudan and to study the etiological factors involved. A further objective was to explore the use of serum thyroglobulin (Tg) level in the assessment of endemic goiter. The survey took place in the period from June to November 2006. The survey covered nine cities including Nyala and Elfasher (Western part), Wau (in the South), Atbara and Dongula (in the north), Dmazine (South East), Port Sudan (Eastern part), Kosti and Khartoum (in the Centre ). Khartoum was divided into three different cities Khartoum, Khartoum North and Omdurman. The study included 6181 male and female schoolchildren at the age 6-12 years old. All the children were clinically examined for the presence of goiter using WHO palpation method. Blood samples were randomly collected from 360 children (30-37) from each selected city irrespective of their thyroid status or gender. Serum samples were analyzed for the concentration of T4, T3, TSH, and Tg. Casual urine samples were also collected from the same selected subjects. Urine samples were analyzed for iodine and thiocyanate concentrations. Water samples were collected from each school and analyzed for the concentration of Ca, Mg, Cl, F and total Hardness. The results indicated that the overall total goiter rate was 40.62%. The highest goiter rate was found in Kosti town (77.67%) and the lowest in Omdurman Khartoum state (12.22%). The overall median urinary iodine excretion (UIE) was 6.55 μg/dl. Iodine deficiency was detected in 70.28% of the children and there were great variations in the median UIE from region to anther started from as low as 2.70μg/d1 in Kosti town 46.40 μg/d1 in Port Sudan city (at the cost of the Red Sed). The overall median concentration of urinary thiocyanate was 0.37 mg/d1. There were also variations in the median levels of urinary thiocyanate from city to another and slightly exceeded the cut off point (0.0.46 mg/d1) in pupils from Wau and Nyala cities

The overall annual effective dose was below the WHO reference dose level of 0.1 mSv yr{sup -1} except in one groundwater sample with an associated dose of 0.7 mSv yr{sup -1}.

  2. Economic development and the allocation of petroleum products in Sudan

    International Nuclear Information System (INIS)

    The Sudanese economy has been characterized in recent years by severe energy shortages which have affected all economic activity. More than 94% of the commercial energy is imported and the level of such imports is seriously limited by the current foreign exchange crisis. However, the problem is not just one of foreign exchange; there is also the problem of utilization of resources to avoid bottleneck problems of supply. The allocation of petroleum products in Sudan has had a severe effect on all aspects of economic life. The aim of this paper is to highlight the problem and to build a model to optimize the distribution of petroleum products in order to achieve at least a minimal supply in all regions. A large linear programming model has been developed and the solution indicates that current facilities should be able to satisfy 96% of the 1986 demand, about 30% more than the actual supply. Furthermore, with a little investment in storage facilities and extra trucks, the supply could satisfy total demand in the immediate future

  3. X-ray diffraction analysis of mudstone from nw sudan

    International Nuclear Information System (INIS)

    This study deals with the theoretical and experimental aspects of the x-ray diffraction technique (XRD). The XRD technique is used to investigate fine structure of matter, and it is most efficient method for the determination of the mineralogical composition of rocks. The XRD technique is used also to investigate the clay mineralogical of mud-stones of the Nubian sandstones of north western Sudan. The XRD results revealed that the mud-stone samples are composed, in decreasing abundance's of kaolinite, smectite, chlorite and illite. Non-clay minerals reported include quartz, feldspars and geothite. Kaolinite dominates in most of samples with percentages ranging between 78-96%. Smectite comes second in abundance and ranges between 10-24%, followed by chlorite and illite which showed the lowest abundance's. The dominance of kaolinite over smectite indicates that intense chemical weathering and leaching occurred under warm humid climate interrupted by dry periods. Most probably these clay minerals were produced by inheritance and partly by neo formation. The variation of the chemical composition of these mud stones is due basically to differences in clay mineralogy which was controlled by source rock geology, weathering physicochemical behavior of elements, local environment and climatic condition in the past.

    Roseires Reservoir, located on the Blue Nile River in Sudan, is the first trap to the sediments coming from the vast upper river catchment in Ethiopia, which suffers from high erosion and desertification problems. The reservoir has already lost more than one-third of its storage capacity due to sedimentation in the last four decades. Appropriate management of the eroded soils in the upper basin could mitigate this problem. In order to do that, the areas providing the highest sediment volumes to the river have to be identified, since they should have priority with respect to the application of erosion control practices. This requires studying the sedimentation record inside Roseires Reservoir in order to assess when and how much sediment is deposited and to identify its source. This paper deals with the identification of deposition time and soil stratification inside the reservoir, based on historical bathymetric data, numerical modelling and newly acquired soil data. The remoteness of the study area and the extreme climate result in coring campaigns being expensive and difficult. Therefore, these activities need to be optimised and coring locations selected beforehand. This was done by combining bathymetric data and the results of a depth-averaged morphodynamic model recording the vertical stratification in sediment deposits. The model allowed for recognising the areas that are potentially subject to neither net erosion nor bar migration during the lifespan of the reservoir. Verification of these results was carried out by analysing sediment stratification from the data collected during the subsequent field campaign.

  5. Characterisation of phosphate rocks at kurun mountain, Sudan

    International Nuclear Information System (INIS)

    This main objective of this study was to characterise some Sudanese phosphate raw materials collected from Jebel Kurun, located in the eastern part of Nuba Mountain, Western Sudan. The study also aimed to investigate the association between uranium and phosphate and to determine the concentration of some essential elements and trace elements in the phosphate rock. A total of 30 samples were collected from Karun's eastran mountains, near Abujibiha City and have been analyzed for the selected elements using x-ray fluorescence. The obtained results showed that the average concentration of elements was Ca (11.3) and Fe (1.7) as a percentage, while it was Cu (1617.7), Ni (258.4), Pb (185.9), Ti (27.62), V (3779.9), U (160.9), Zn (152.8) and Mn (776.3) in ppm. The average total phosphorus content (analyzed as PO5%) using UV-visible spectrometer was found to be 30.54%. This could be considered is acceptable percentage for phosphate to be 30.54%. This could be considered is acceptable percentage for phosphate to be used in industrial fertilizers and phosphoric acid production. The average total calcium carbonate was 15.7%. For the elements distribution, uranium found to be more concentrated in the summit of Jebel Kurun, and it displayed a correlation with lead. Furthermore, four groups of association have been noticed, based on elements concentrations.(Author)

    Full Text Available This field study was conducted between Oct 2005 and Aug 2008 in Gedarif state, eastern Sudan. The objective was to provide knowledge on constraints faced by camel herders, and to identify the solutions as an essential step towards the development of camel herding in this state. A set of detailed structured questionnaires were used to collect information from camel herders. The results showed that, nomadic tribes in the study area (58.8% represented by Lahaween and Rofaah tribes and their dwelling type is tents made from (Hair & wool. Semi nomadic tribes (30.9% represented by Kenana and Rashaida tribes and their dwelling type is cottage made from branches of trees and sorghum stalk and the sedentary tribe (10.3% represented by Shokria tribes and their dwelling type are buildings made from either mud or bricks with cement. There was a high percent of family members who are illiterate. It was clear that the level of provision of most services needed by the herders and owners is relatively very low. The camel owners annually need to sell 5 to 6 camels to feed 100 camels on sorghum stalks in the dry season. The serious livelihood constraints were education, electricity, water supply and veterinary services. More care from the government and non government organizations is recommended.

    A semi- aquatic plant, Polygnum glabrum wild of the family polygonaceae was reported in traditional medicine of Sudan as anthelmintic and as a remedy against intestinal colics.The literature reported the isolation and structure elucidation of the bioactive agents as being sequi terpenes. The flavonoids of the Sudanese species were not investigated before. The present work consisted of phyto chemical study of the leaves of Polygonum galbrum wild. Before experimentation, a through authentication of the plant was done to correct previously reported errors. In the first stages a phyto chemical screening was made which confirmed the presence of flavonoid compounds in higher amounts than the other classes of natural products present in the plant. Different chromatographic techniques of isolation were assayed but the fractionation of flavonoids was successfully done with preparative thin layer chromatographic techniques. Yellow crystals, namely (two compounds) were obtained in pure form and identified as being flavonoids. Spectral studies were performed on Infra-Red and Ultra- Violet spectrophotometers. The computerized Ultra- Violet spectrophotometer allowed us to obtain complete data about the studied compounds. Structure elucidation was attempted and the structure of the isolated flavonoids were suggested as being Isorhamnetin and Diosmetin. (Author)

    Full Text Available The author analyzes the problem of covering by mass media the military events of September-October 2014 in the area of Kobani located on the Syrian-Turkish border, shows the ideological significance of the city for the Kurdish population. The article considers the peculiarities of interaction between the Iraqi and Syrian Kurdistan and Turkey's position in this matter. The author presents the information obtained by him personally and directly from the event in the process of his journalistic activities. According to a source of the Fox News TV channel, «Seizing Kobani can be an important victory for the ISIL; in this case there will be a serious concern that the Sunni military group is advancing ahead despite the air strikes made by the coalition,» said Fox News. Analyzing the impact of information processes on the course of the modern armed conflict on the example of the events in Kobani, we can conclude that political, ideological and geopolitical views are formed among a large part of society solely on the basis of telecommunication. Mass media in modern society play not only an auxiliary role, as in the past, but become a powerful independent factor that can make a strong impact on the historical destiny of the people.

    Full Text Available Background: The most common mental health problems among refugees are depression and posttraumatic stress disorder (PTSD. Eye movement desensitization and reprocessing (EMDR is an effective treatment for PTSD. However, no previous randomized controlled trial (RCT has been published on treating PTSD symptoms in a refugee camp population. Objective: Examining the effect of EMDR to reduce the PTSD and depression symptoms compared to a wait-list condition among Syrian refugees. Method: Twenty-nine adult participants with PTSD symptoms were randomly allocated to either EMDR sessions (n=15 or wait-list control (n=14. The main outcome measures were Impact of Event Scale-Revised (IES-R and Beck Depression Inventory (BDI-II at posttreatment and 4-week follow-up. Results: Analysis of covariance showed that the EMDR group had significantly lower trauma scores at posttreatment as compared with the wait-list group (d=1.78, 95% CI: 0.92–2.64. The EMDR group also had a lower depression score after treatment as compared with the wait-list group (d=1.14, 95% CI: 0.35–1.92. Conclusion: The pilot RCT indicated that EMDR may be effective in reducing PTSD and depression symptoms among Syrian refugees located in a camp. Larger RCTs to verify the (cost- effectiveness of EMDR in similar populations are needed.

    Background and objectives Blood transfusion is a lifesaving therapy for patients with hemoglobinopathies. However, the need of frequent transfusion carries the risk of transmitting hepatitis B and C infections which are intermediately prevalent in Syria. Despite screening blood donations with sensitive methods, the risk of transmission is still present when infectious blood is donated within the window period. This study aimed to investigate the incidence of HBV and HCV seropositivity, and its association with multiple transfusions among Syrian hemoglobinopathies patients. Materials and Methods HBsAg, anti-HBc, anti-HBs and anti-HCV were tested for 159 Syrian multi-transfused patients by Enzyme-Linked Immunosorbent Assay (ELISA). Results Thirty-nine of 159 (24.5%) multi-transfused patients were HBsAg/anti-HBc or anti-HCV positive, 26 (16%) of which never visited the dentist, and they either tested postsurgically negative for HBsAg and anti-HCV or never underwent a surgical procedure. On the contrary of anti-HCV seropositivity, HBsAg/anti-HBc seropositivity was significantly associated with the number of blood transfusions, number of blood units and age (P < 0.001). Conclusion About one-sixth of our patients most likely acquired HBV/HCV infection via blood transfusion. Administering HBV vaccine, ensuring the immune status, and monitoring hepatitis markers might considerably minimize the incidence of viral hepatitis among multi-transfused patients. PMID:27648209

    Full Text Available Human papillomavirus (HPV infection is the most common sexually transmitted infection; persistent infection with high-risk types of HPV present a major risk factor for the initiation and progression of a variety of human carcinomas including cervical, colorectal, head and neck as well as breast carcinomas. A huge number of studies investigated and reported the incidence of high-risk HPVs in these cancers worldwide particularly in the developed countries; therefore, two HPV prophylactic vaccines against the two most frequent high-risk HPV types (16 and 18 have been developed and used worldwide. However, there are very limited studies about the prevalence of HPVs in the developing countries especially in Africa and some states of the Middle East (ME. In this mini review, we outline the presence of high-risk HPVs in human cervical, colorectal, head and neck as well as breast cancers in the Syrian population, which was recently explored for the first time by a Canadian/Syrian group.

  15. Subcellular distribution of Pu-239 in the liver of rat, mouse, Syrian and Chinese hamster

    International Nuclear Information System (INIS)

    The aim of our studies was to elucidate the biochemical mechanisms responsible for the differences in the biological half life of actinides in the liver of different mammalian species. Rats and mice were chosen as models for rapid elimination, and Syrian and Chinese hamsters as models for slow elimination. To distinguish between fixation in lysosomes and mitochondria, the lysosomes were isolated following injection of Triton WR1339 6 days after 239Pu administration. The animals were sacrificed 4 days later. In order to study the possible association with ferritin, 59Fe was also injected. Liver homogenates were subjected to differential and isopycnic centrifugation in a sucrose density gradient. The typical shift in the density of the lysosomal marker acid phosphatase from rho approximately 1.2 to rho approximately 1.1 following Triton WR1339 injection was observed in all species. It was possible therefore to separate lysosomes from other cell organelles, especially mitochondria. It was concluded that: 1) Mitochondria can virtually be excluded as binding sites in all four species; 2) Lysosomes are one important storage site in rats, mice and Syrian hamsters; 3) If 239Pu is bound to another cell constituent in addition to lysosomes in the hamster species (which is not yet proven) its density should be approximately 1.17.

    This study examined the relation between waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHpR), waist-to-height ratio (WHtR) and triceps skin-fold thickness and percentage body fat in young Syrian men. The aim was to develop equations that can use these anthropometric characteristics to estimate percentage body fat in this group of subjects. A total of 2470 healthy Syrian men aged 18-19 years were enrolled in the study in 2010-2011. The anthropometric characteristics of all subjects were measured. The percentage body fat of 213 of the subjects was determined using the deuterium dilution (DD) technique as a reference method. The validity of using WC, HC, WHpR and WHtR to calculate percentage body fat, in comparison with the reference method (DD technique), was assessed by calculating biases and limits of agreement. The estimates of percentage body fat using 'WC' and 'WC with triceps skin-fold' measurements ranged from 13.00±5.56% to 14.55±8.63%, and were lower than those determined using the reference method (21.32±6.42%). A better prediction equation is proposed for young adults, based on a multiple linear regression model using WC, HC and WHtR. PMID:26971838

To examine this theme, this paper will adopt the Syrian Arab Republic as a case. To understand the Syrian government's policy toward the ICT development, it is necessary to examine the domestic political situation, since they are closely related. Under the Bashar Al- Asad's regime, we can confirm several reasons why they have to move forward on their ICT development policy and why it has become a crucial issue, which they cannot evade, as they had done under the previous regime, Hafez Al- Asad's regime. The situation that the Syrian government is facing right now is known by the term, "Dictator's Dilemma". This paper tries to provide bases in order to examine and explore this dilemma in Syria. Also, when we examine ICT development in Syria, it is important to consider the ICT support policies, which are mainly conducted by OECD countries and international organizations and stem from the issue of "Digital Divide". This is why international assistances could have great effect on ICT development in Syria. As a provisional conclusion of this paper, I will summarize how we can understand the current situation of ICT development in Syria, and I will also comment on the future prospect of the dilemma that the Syrian government is facing at the present time.

    2005-09-01

    Full Text Available Hyalomma anatolicum anatolicum nymphs were collected from two localities in the Sudan: Eddamer in Northern Sudan and Wad-Medani in Central Sudan. They were allowed to moult to adult ticks, which were assessed for Theileria infection in their salivary glands using Feulgen stain. At Eddamer, 49.6 % of 123 ticks examined were infected with Theileria and the mean intensity of infection was 1.3 (i.e. the number of infected acini / number of infected ticks. At Wad-Medani, 8.6 % of 162 ticks were infected and the mean intensity of infection was 7.9. The prevalence of infection was higher in female than in male ticks at both localities. When adult H. a. anatolicum were applied onto two susceptible calves, both animals developed the severe form of theileriosis.

    The epidemiological aspects of sheep piroplasmosis in Sudan are poorly studied, and further investigations using sensitive and precise techniques are required. In this study, the Reverse Line Blot (RLB) hybridization assay was used to detect and simultaneously differentiate between Theileria and Babesia species. DNA was extracted from blood collected on filter paper (n=219) from apparently healthy sheep from six different geographical localities in Sudan. Results indicated that Theileria ovis (88.6%), T. separata (20.1%), T. lestoquardi (16.4%) and T. annulata (16.4%) DNA could be detected in the blood samples. Single and mixed Theileria infections were detected in 74 (33.8%) and 124 (56.6%) respectively and T. ovis being the most prevalent species in the country. T. ovis and T. separata were reported for the first time in sheep in Sudan.

    Full Text Available The research aimed to investigate the difference in performance of pure Saanen goats reared in Sudan and Swiss the origin of the animal considering birth weight, twining, puberty, mating age, gestation period, motility rate, milk production and quality. 200 does from Goat Research Centre (GRC at Khartoum were used for the study for three consecutive years (2008-2010. The results show that hot climate (Sudan delayed the reproductive parameters of the goat and increased the mortality rate. On the other hand milk production decreased but no change in the quality was observed. The research concluded that keeping pure Saanen in Sudan is not beneficial and it is recommended to cross the animal with local breeds. Moreover, improve the environment for better performance and welfare of the animals.

    Full Text Available A new genus is proposed for the strikingly patterned African vespertilionid “Glauconycteris” superba Hayman, 1939 on the basis of cranial and external morphological comparisons. A review of the attributes of a newly collected specimen from South Sudan (a new country record and other museum specimens of “G.” superba suggests that “G.” superba is markedly distinct ecomorphologically from other species classified in Glauconycteris and is likely the sister taxon to Glauconycteris sensu stricto. The recent capture of this rarely collected but widespread bat highlights the need for continued research in tropical sub-Saharan Africa and in particular, for more work in western South Sudan, which has received very little scientific attention. New country records for G. cf. poensis (South Sudan and G. curryae (Gabon are also reported.

  7. Towards global Guinea worm eradication in 2015: the experience of South Sudan.

    Awofeso, Niyi

    2013-08-01

    For centuries, the Guinea worm parasite (Dracunculus medinensis) has caused disabling misery, infecting people who drink stagnant water contaminated with the worm's larvae. In 2012, there were 542 cases of Guinea worm reported globally, of which 521 (96.1%) were reported in South Sudan. Protracted civil wars, an inadequate workforce, neglect of potable water provision programs, suboptimal Guinea worm surveillance and case containment, and fragmented health systems account for many of the structural and operational factors encumbering South Sudan's Guinea worm eradication efforts. This article reviews the impacts of six established Guinea worm control strategies in South Sudan: (1) surveillance to determine actual caseload distribution and trends in response to control measures; (2) educating community members from whom worms are emerging to avoid immersing affected parts in sources of drinking water; (3) filtering potentially contaminated drinking water using cloth filters or filtered drinking straws; (4) treating potentially contaminated surface water with the copepod larvicide temephos (Abate); (5) providing safe drinking water from boreholes or hand-dug wells; and (6) containment of transmission through voluntary isolation of each patient to prevent contamination of drinking water sources, provision of first aid, and manual extraction of the worm. Surveillance, community education, potable water provision, and case containment remain weak facets of the program. Abate pesticide is not a viable option for Guinea worm control in South Sudan. In light of current case detection and containment trends, as well as capacity building efforts for Guinea worm eradication, South Sudan is more likely to eradicate Guinea worm by 2020, rather than by 2015. The author highlights areas in which substantial improvements are required in South Sudan's Guinea worm eradication program, and suggests improvement strategies. PMID:23623648

    Polymorphic genetic markers and especially microsatellite analysis can be used to investigate multiple aspects of the biology of Plasmodium species. In the current study, we characterized 7 polymorphic microsatellites in a total of 281 Plasmodium vivax isolates to determine the genetic diversity and population structure of P. vivax populations from Sudan, Madagascar, French Guiana, and Armenia. All four parasite populations were highly polymorphic with 3-32 alleles per locus. Mean genetic diversity values was 0.83, 0.79, 0.78 and 0.67 for Madagascar, French Guiana, Sudan, and Armenia, respectively. Significant genetic differentiation between all four populations was observed.

  10. A review of soil conservation in the Sudan (1940-1979)

    International Nuclear Information System (INIS)

    Soil Conservation in the Sudan started in the late thirties, and in 1942 a Soil Conservation Committee was set up to report on Soil Conservation Situation. Later a Soil Conservation Section was set which developed into a department taking the responsibility of drinking water points distribution and soil and water management in rural areas. In 1974 a desert encroachment project was proposed to cover most affected areas with the help of F.A.O. Soil Conservation is an important problem in Sudan and much work is needed to tackle this problem. The application of radioisotope and radio-tracer techniques are also needed for tackling this problem. (author)

    Full Text Available Literature is ripe with the scholarly contributions on brand development from all aspects. The new marketing tools and techniques are introduced frequently. However, the impact social media has had on brand development is no match to traditional promotion in 4Ps. The information about Saudi Arabia is specially rare. This article based on a survey of 200 social media users on www.surveymonkey.com evaluates the role of social media in brand development in Saudi Arabia. The results from this Saudi example show that social media including Facebook and Twitter are among the most effective tool to develop a brand as compared to traditional promotional methods. It has also been found that these media are more successful in Saudi Arabia to develop the brand recall and image.

    2008-11-01

    Full Text Available Abstract Background Medical education in Saudi Arabia is facing multiple challenges, including the rapid increase in the number of medical schools over a short period of time, the influx of foreign medical graduates to work in Saudi Arabia, the award of scholarships to hundreds of students to study medicine in various countries, and the absence of published national guidelines for minimal acceptable competencies of a medical graduate. Discussion We are arguing for the need for a Saudi national medical licensing examination that consists of two parts: Part I (Written which tests the basic science and clinical knowledge and Part II (Objective Structured Clinical Examination which tests the clinical skills and attitudes. We propose this examination to be mandated as a licensure requirement for practicing medicine in Saudi Arabia. Conclusion The driving and hindering forces as well as the strengths and weaknesses of implementing the licensing examination are discussed in details in this debate.

  16. Rabies in Saudi Arabia: a need for epidemiological data

    Directory of Open Access Journals (Sweden)

    Ziad A. Memish

    2015-05-01

    Full Text Available Rabies is endemic in animals in the Arabian Peninsula. Although Saudi Arabia is the largest country in the Peninsula, little has been published about the rabies situation in the country. A total of 11 069 animal bites to humans were reported during 2007–2009, and 40 animals suspected of rabies were examined for rabies infection from 2005 through 2010. Results suggest that animal-related injuries in Saudi Arabia remain a public health problem, with feral dogs accounting for the majority of bites to humans and for the majority of animals found to be rabid. Over the last 10 years, no confirmed human rabies case has been reported. More detailed information about the epidemiology of animal bites and that of animal rabies in Saudi Arabia would be of great interest, notably to provide a basis on which vaccination recommendations could be made for the numerous international travellers visiting the country.

  17. Supervolcanoes Within an Ancient Volcanic Province in Arabia Terra, Mars

    Michalski, Joseph. R.; Bleacher, Jacob E.

    2014-01-01

    Several irregularly shaped craters located within Arabia Terra, Mars represent a new type of highland volcanic construct and together constitute a previously unrecognized martian igneous province. Similar to terrestrial supervolcanoes, these low-relief paterae display a range of geomorphic features related to structural collapse, effusive volcanism, and explosive eruptions. Extruded lavas contributed to the formation of enigmatic highland ridged plains in Arabia Terra. Outgassed sulfur and erupted fine-grained pyroclastics from these calderas likely fed the formation of altered, layered sedimentary rocks and fretted terrain found throughout the equatorial region. Discovery of a new type of volcanic construct in the Arabia volcanic province fundamentally changes the picture of ancient volcanism and climate evolution on Mars. Other eroded topographic basins in the ancient Martian highlands that have been dismissed as degraded impact craters should be reconsidered as possible volcanic constructs formed in an early phase of widespread, disseminated magmatism on Mars.

  18. Introducing SMART Table Technology in Saudi Arabia Education System

    2013-03-01

    Full Text Available Education remains one of the most important economic development indicators in Saudi Arabia. This is evident in the continuous priority of the development and enhancement of education. The application of technology is crucial to the growth and improvement of the educational system in Saudi Arabia. Introducing SMART Table technology in the Saudi Arabian education system is argued in this paper as being able to assist teachers and students in the process of accommodating both technological changes and new knowledge. SMART Tables also can enhance the level of flexibility in the educational system, thus improving the quality of education within a modern Saudi Arabia. It is crucial to integrate technology effectively and efficiently within the educational system to improve the quality of student outcomes. This study will consider the potential benefits and recommendations associated with the adoption of SMART Tables in Saudi Arabian education system.

    2016-04-01

    Invited Paper Forty years ago Colin Renfrew declared that "every archaeological problem starts as a problem in geoarchaeology" (Renfrew, 1976 p. 2). With this assertion in mind, this paper draws upon the findings from field research in two sectors of the Nile Valley of Northern Sudan dedicated to the exploration of human-environment interactions during the middle and late Holocene. This part of the Nile corridor contains a rich cultural record and an exceptionally well preserved Holocene fluvial archive. A distinctive feature of these records is the variety of evidence for interaction between desert and river over a range of spatial and temporal scales. This interaction presented both challenges and opportunities for its ancient inhabitants. This paper will present evidence for large-scale landscape changes driven by shifts in global climate. It will also show how we have integrated the archaeological and geological records in the Northern Dongola Reach and at Amara West - where long-term field projects led by archaeologists from the British Museum have recognised the importance of a sustained commitment to interdisciplinary research to achieve a fully integrated geoarchaeological approach across a range of scales. The former project is a large-scale landscape survey with multiple sites across an 80 km reach of the Nile whilst the latter has a strong focus on a single New Kingdom town site and changes in its environmental setting. By combining multiple archaeological and geological datasets - and pioneering the use of OSL dating and strontium isotope analysis in the Desert Nile - we have developed a new understanding of human responses to Holocene climate and landscape change in this region.

  20. Dose survey of pediatric and adult patients in Sudan

    International Nuclear Information System (INIS)

    A survey of radiation doses to children and adults from diagnostic radiography has been carried out in seven hospitals in Sudan. In four hospitals only pediatric examinations were died. In two hospitals only adult patients were recorded and in one hospital both kinds of patients (pediatric and adults) were evaluated. For pediatric patients only chest x-ray examination was evaluated and children were divided according to age ranges: from (0-1) and 5) years for chest AP only and from (5-10) and (10-15) for chest PA. For adult patients the examinations were chest AP and PA, abdomen AP and skull AP and PA. Entrance Surface Dose SD) and the Effective Dose (E) were calculated using the Dose Cal software. The mean ESD r children, measured in p.Gy, ranged from (45-53) and (53-56) for (0-1) and (1-5) years, respectively and from (55-71) and (68-85) for (5-10) and (10-15) years, respectively. In two of le pediatric hospitals the mean ESD values were greater than the CEC Reference Dose Levels. In El bulk and Si nar hospitals the values ranged from 167-261 and 186-308 μGy for the age ranges (0-1) and (1-5) respectively and 167-194 and 279-312 μGy for the age ranges of (5-10) and (10-15) respectively. For adult patients the ESD and E dose values evaluated in Alfisal hospital presented values comparable with the CEC Reference Dose Level. However for Alshorta hospital the values were higher for the chest AP and PA with results for ESD 0.446 and 0.551 mGy respectively

  1. Oral health of visually impaired schoolchildren in Khartoum State, Sudan

    Science.gov (United States)

    2013-01-01

    Background Although oral health care is a vital component of overall health, it remains one of the greatest unattended needs among the disabled. The aim of this study was to assess the oral health status and oral health-related quality of life (Child-OIDP in 11-13-year-old) of the visually challenged school attendants in Khartoum State, the Sudan. Methods A school-based survey was conducted in Al-Nour institute [boys (66.3%), boarders (35.9%), and children with partial visual impairment (PVI) (44.6%)]. Two calibrated dentists examined the participants (n=79) using DMFT/dmft, Simplified Oral Hygiene Index (OHI-S), dental care index, and traumatic dental injuries (TDI) index. Oral health related quality of life (C-OIDP) was administered to 82 schoolchildren. Results Caries experience was 46.8%. Mean DMFT (age≥12, n=33) was 0.4 ± 0.7 (SiC 1.6), mean dmft (age<12, n=46) was 1.9 ±2.8 (SiC 3.4), mean OHIS 1.3 ± 0.9. Care Index was zero. One fifth of the children suffered TDI (19%). Almost one third (29%) of the 11–13 year old children reported an oral impact on their daily performances. A quarter of the schoolchildren (25.3%) required an urgent treatment need. Analysis showed that children with partial visual impairment (PVI) were 6.3 times (adjusted) more likely to be diagnosed with caries compared to children with complete visual impairment (CVI), and children with caries experience were 1.3 times (unadjusted) more likely to report an oral health related impact on quality of life. Conclusions Visually impaired schoolchildren are burdened with oral health problems, especially caries. Furthermore, the 11-13 year olds' burden with caries showed a significant impact on their quality of life. PMID:23866155

  2. Pathogenesis and immunology of ruminant schistosomiasis in the Sudan

    International Nuclear Information System (INIS)

    Schistosoma bovis in the Kosti area (Sudan) was almost 90% in cattle up to 2 years old but fell to around 30% by 10 years of age. Infection incidence followed a markedly seasonal pattern of transmission. Infected animals either lost weight or gained less weight than controls. This was associated with the development of severe anaemia and hypoalbuminaemia, which in turn were due to massive blood and plasma losses through the gut mucosa. The epizootiological work suggested that cattle can acquire resistance to S. bovis as a result of repeated field infections. This was tested by artificially challenging field-infected cattle, together with animals of similar age and breed from a non-enzootic area. Animals reared in an enzootic environment clearly become solidly resistant to a cercarial challenge sufficient to cause fatal disease in cattle from non-enzootic areas. The mechanisms responsible for this phenomenon are being studied. Immunization with irradiated vaccines was tested in the laboratory. A marked reduction in the faecal egg counts, worm burdens, tissue egg counts and clinical manifestations of the vaccinated compared with non-vaccinated cattle and sheep indicated significant protection. Vaccination efficacy was also tested under field conditions. A group of calves was immunized with irradiated S. bovis schistosomula and a second group served as controls. These animals were released into the field in the enzootic area of Kosti and followed up for 10 months. The results showed 80% reduction in the faecal egg counts and about 70% protection in terms of reduced worm and tissue egg counts in vaccinated compared with non-vaccinated calves. Further evidence of resistance was shown by the lower mortality rate in the former animals. Vaccination against schistosomiasis can be of practical benefit to livestock

    2011-06-01

    Full Text Available Abstract Background Investigation of maternal near-miss is a useful complement to the investigation of maternal mortality with the aim of meeting the United Nations' fifth Millennium Development Goal. The present study was conducted to investigate the frequency of near-miss events, to calculate the mortality index for each event and to compare the socio-demographic and obstetrical data (age, parity, gestational age, education and antenatal care of the near-miss cases with maternal deaths. Methods Near-miss cases and events (hemorrhage, infection, hypertensive disorders, anemia and dystocia, maternal deaths and their causes were retrospectively reviewed and the mortality index for each event was calculated in Kassala Hospital, eastern Sudan over a 2-year period, from January 2008 to December 2010. Disease-specific criteria were applied for these events. Results There were 9578 deliveries, 205 near-miss cases, 228 near-miss events and 40 maternal deaths. Maternal near-miss and maternal mortality ratio were 22.1/1000 live births and 432/100 000 live births, respectively. Hemorrhage accounted for the most common event (40.8%, followed by infection (21.5%, hypertensive disorders (18.0%, anemia (11.8% and dystocia (7.9%. The mortality index were 22.2%, 10.0%, 10.0%, 8.8% and 2.4% for infection, dystocia, anemia, hemorrhage and hypertensive disorders, respectively. Conclusion There is a high frequency of maternal morbidity and mortality at the level of this facility. Therefore maternal health policy needs to be concerned not only with averting the loss of life, but also with preventing or ameliorating maternal-near miss events (hemorrhage, infections, hypertension and anemia at all care levels including primary level.

  4. Essays on oil and business cycles in Saudi Arabia

    Science.gov (United States)

    Aba Alkhail, Bandar A.

    This dissertation consists of three chapters. Chapter one presents a theoretical model using a dynamic stochastic general equilibrium (DSGE) approach to investigate the role of world oil prices in explaining the business cycle in Saudi Arabia. This model incorporates both productivity and oil revenue shocks. The results indicate that productivity shocks are relatively more important to business cycles than oil shocks. However, this model has some unfavorable features that are associated with both investment and labor hours. The second chapter presents a modified theoretical model using DSGE approach to examine the role of world oil prices versus productivity shocks in explaining the business cycles in Saudi Arabia. To overcome the unfavorable features of the baseline model, the alternative model adds friction to the model by incorporating investment portfolio adjustment cost. Thus, the alternative model produces similar dynamics to that of the baseline model but the unfavorable characteristics are eliminated. Also, this chapter conducts sensitivity analysis. The objective of the third chapter is to empirically investigate how real world oil price and productivity shocks affect output, consumption, investment, labor hours, and trade balance/output ratio for Saudi Arabia. This chapter complements the theoretical model of the previous chapters. In addition, this study builds a foundation for future studies in examining the impact of real world oil price shocks on the economies of key trade partners of Saudi Arabia. The results of the third chapter show that productivity shocks matter more for macroeconomic fluctuations than oil shocks for the Saudis' primary trade partners. Therefore, fears of oil importing countries appear to be overstated. As a whole, this research is important for the following reasons. First, the empirical model is consistent with the predictions of our theoretical model in that productivity is a driving force of business cycles in Saudi Arabia

    We have performed 3-D scaled lithospheric experiments to investigate the role of the gravitational force exerted by subduction slab on the deformation of the subducting plate itself. Experiments have been constructed using a dense silicone putty plate, to simulate a thin viscous lithosphere, floated in glucose syrup, simulating the upper mantle. We show different plate configuration: (i) subduction of a uniform oceanic plate, (ii) subduction of oceanic-continental plate system, and (iii) subduction of a more complex oceanic-continental system simulating the asymmetric Africa-Eurasia system at the beginning of the Tertiary. Each model has been performed including or not the presence of circular weak zone inside the subducting plate simulating the near-surface weakening effect of a plume activity. Our results show that a subducting plate can deform in its interior only if the velocity field generated by the slab varies laterally along the subduction zone, i.e. by the asymmetrical entrance of continental material at trench. The result of this study can be used to analyze the formation of the Arabian plate. We found that intraplate stresses, similar to the one that generated the Africa-Arabia break-up, can be related to the Neogene evolution of the northern convergent margin of the African plate where a lateral change from collision (Mediterranean and Bitlis) to active subduction (Makran) has been described. Second, intraplate stress and strain localization are favored by the presence of a weakness zone, such as the one generated by the Afar plume, producing a pattern of extensional deformation belts resembling to the Red Sea-Gulf of Aden rift system.

    Full Text Available Background and Objectives: The blood donor system in the Kingdom of Saudi Arabia depends on a combination of voluntary and involuntary donors. The aim of this study is to explore the attitudes, beliefs and motivations of Saudis toward blood donation. Materials and Methods: The study was conducted at the Donor Centers at King Khalid University Hospital (KKUH Blood Bank and King Saud University Students Health Center, Riyadh. A self-administered questionnaire was distributed to donors (n = 517 and nondonors (n = 316, between February and June 2008. All were males. Results: Ninety-nine percent of the respondents showed positive attitude toward blood donations and its importance for patients care, and object the importation of blood from abroad. Blood donors: Ninety-one percent agree that that blood donation is a religious obligation, 91% think no compensation should be given, 63% will accept a token gift, 34% do not object to donating six times/year and 67% did not mind coming themselves to the donor center to give blood. Nondonors: Forty-six percent were not asked to give blood and those who were asked mentioned fear (5% and lack of time (16% as their main deterrents. Reasons for rejection as donors include underweight and age (71% and health reasons (19%. Seventy-five percent objected to money compensation but 69% will accept token gifts and 92% will donate if a relative/friend needs blood. Conclusion: These results reflect an encouraging strong positive attitude toward blood donation. Further future planning with emphasis on educational/publicity programs and careful organization of donor recruitment campaigns could see the dream of total voluntary nonremunerated blood donations should not take long to be true.

    Following exposure to the alkaloid noscapine hydrochloride over a concentration range of 10-120 micrograms/ml immortal cultures of Syrian hamster dermal fibroblasts were shown to undergo morphological transformation. The resultant transformed foci produced cultures which were anchorage independent as confirmed by soft agar tests. Karyotype analysis of a noscapine transformed colony demonstrated an increase in chromosome number compared to the immortal culture and the non-random duplication of a translocated chromosome 9 previously identified in the immortal culture. These data indicate that noscapine, which has previously been shown to be a spindle inhibitor and inducer of polyploidy in cultured cells, is capable of inducing in vitro cell transformation. Such data indicate a carcinogenic potential for this widely used cough suppressant. PMID:1602976

  9. Removal of Ammonium from Aqueous Solutions by Syrian Natural Ores Containing Zeolite

    International Nuclear Information System (INIS)

    In this paper we study the removal of ammonia from aqueous solutions which have the same concentration of ammonia in the Wady-Kandel water in Lattakia. We used natural Syrian ores containing zeolite. The mechanism was according to ion-exchange process. The results show that the ion-exchange capacity (IEC) has a clear relation with the equilibrium concentration and it was 0.88mg/g when Ce=0.5mg/l. This work shows that for purification 1 m3 of the solution which has 2.3mg/l, we need 2kg of zeolite. The bedvoleum equals 4 in breakthrough point and the exchanged amount of ammonia was 0.2mg/g.(author)

  10. Air pollution with particulates and heavy metals in some Syrian cities

    International Nuclear Information System (INIS)

    A study of air pollution in different sites of five Syrian cities (Damascus, Aleppo, Tartous, Homs, and Sweda) was carried out. The concentrations of total suspended particulate less than 10 microns (PM 10) and less than 3 micron (PM3) were measured using high volume air sampler (HVAS). Heavy element concentration, Pb, Cd, Zn and Cu were also determined using high volume air sampler (HVAS). Heavy element concentrations, Pb, Cd, Zn and Cu were also determined using anodic stripping voltammetry. The result showed that TSP, PM10 and PM3 were higher than WHO standards in several times. Mean lead concentrations ranged between 0.58 and 2.96 μg/m3 and 0.56 and 1.53 μg/m3 in Damascus and Aleppo respectively, while in the other cities these concentrations were less than WHO standards (0.5 - 1 μg/m3).

    Cutaneous leishmaniasis (CL), seen endemically in many countries, is a widespread protozoon disease all around the world. The neighboring countries of Turkey namely Iran, Iraq and Syria are highly endemic regions for CL, and more than 98% of the cases in Turkey are reported from South and Southeastern Anatolian regions. The aim of this study was to detect the prevalence of CL in Nizip, a district of Gaziantep province of southeastern Turkey, for three and half year period and to call attention to the dramatic increase of CL cases observed after the Syrian civil war. A total of 416 samples obtained from clinically suspected CL patients (of them 341 were Syrian refugees) who were admitted to Nizip State Hospital between January 1st 2010 and March 19th 2013 were included in the study. Lesion samples were collected according to the notice issued by Turkish Ministry of Health and Giemsa-stained smears were examined under the microscope (x1000). Samples from 77 patients (18.5%) yielded positive results with the observation of Leishmania amastigote forms. Fourty-seven (61%) of patients were female and 30 (39%) were male. Of the positive patients 52 (67.5%) belonged to 0-19 age group, 13 (16.9%) 20-39 and 12 (15.6%) 40-60 age groups. In the evaluation of the lesion characteristics, 33 (43%) patients had single and 44 (57%) had multiple lesions with a distribution mainly on face, arm and lower extremities, in a decreasing order. The period of time for the development of the lesions varied from 1.5 month to one year with the mean value of 3.4 months. There was no statistically significant relationship between the age and gender of patients, and the characteristics (quantity, distribution and time of occurence) of lesions (p> 0.05). The number of domestic and Syrian CL cases detected in Nizip in the years of 2010, 2011, 2012 and 2013 (the first three months) were as follows; 1 and 0, 2 and 0, 7 and 0, 5 and 62, respectively. So a total of 62 (80.5%) and 15 (19.5%) of CL

    Full Text Available Syrian hamsters (Mesocricetus auratus run extensively in exercise wheels. This running may cause paw lesions. Three treatments of these wounds (topical application of vitamin E, wheel blocking, and a combination of both were compared using both sexes. A pretreatment period with or without wheels lasted 15 days and the ensuing treatment period lasted 45 days. At the end of the pre-treatment period, none of the animals without wheels had paw wounds, whereas at least 75% of the females and 100% of the males with wheels did. Females had fewer and smaller wounds than males at this point. At the end of the treatment period, no effect of vitamin E could be discerned, but significant wound healing occurred after wheel blocking in both males and females. Wheel blocking is an easy way to prevent or treat paw wounds, but it presents problems in terms of animal welfare, as wheels are an important cage enrichment for hamsters.

  13. The impact of phosphate loading activities on near marine environment: The Syrian coast

    International Nuclear Information System (INIS)

    The impact of loading cargoes of phosphate ore into ships on the near marine environment at the Syrian coast has been evaluated. Results have shown a significant enhancement of 210Po, 210Pb and other natural radionuclides in sediment and surface water inside the port area. The highest 210Po and 210Pb concentrations observed in sediment were found to be 170 Bq kg-1 respectively, while 210Po concentrations in surface water ranged from 5 to 20 mBql-1. In addition, comparable values of 210Po and 210Pb for all marine organisms (algae, crab and fish) suggest that their use as indicators for phosphate pollution is not recommended. However, the effect of loading cargoes on Tartous port marine environment of Tartous was found to be mainly related to wind direction where radioactive air particulate are either being dispersed to land or sea.

  15. Chemical and radioactivity study of sea alga distribution along the Syrian coast

    International Nuclear Information System (INIS)

    Three types of sea alga distributed along the Syrian coast have been studied from the chemical and radioactivity point of view. Results have shown the metals that red alga contains the highest levels of Ca and Mg while brown alga were found to contain relatively high concentrations of other elements and non metals such as Cl, I and Br. In addition, 137Cs concentrations in all the analyzed sample were low while the levels of naturally occurring radionuclides such as 210Po, 210Pb and radium isotopes were found to be high in red alga which indicates their selectivity to these isotopes. On the other hand, brown alga and especially Cysteseira has shown a clear selectivity for some trace elements such as As, Cr, Cd, Cu and Co, this selectivity may encourage the use of brown alga as biological indicator for trace elements pollution.

    2011-01-01

    In seasonal breeders, reproduction is synchronised by day length via the pineal hormone melatonin. In short winter days (short day, SD), the Syrian hamster displays a complete gonadal atrophy together with a marked reduction in expression of kisspeptins (Kp), a family of potent hypothalamic...... stimulators of GNRH neurons. Both central and peripheral acute injections of Kp have been reported to activate the gonadotropic axis in mammals. The aim of this study was to determine if and how peripheral administration of Kp54 could restore gonadal function in photo-inhibited hamsters. Testicular activity...... of hamsters kept in SD was reactivated by two daily i.p. injections of Kp54 but not by chronic subcutaneous delivery of the same peptide via mini-pumps. Acute i.p. injection of Kp54-induced FOS (c-Fos) expression in a large number of GNRH neurons and pituitary gonadotrophs together with a strong increase...

    2015-05-01

    The effects of development and the uncertainty of a changing climate in eastern Africa pose myriad challenges for water managers along the Blue Nile. Sudan's large irrigation potential, hydroelectric dams, and prime location within the basin mean that Sudan's water management decisions will have great social, economic and political implications for the region. At the same time, Sudan's water use options are constrained by tradeoffs between upstream irrigation developments and downstream hydropower facilities as well as by the country's commitments under existing or future transboundary water sharing agreements. Here, we present a model that can be applied to evaluate optimal allocation of surface water resources to irrigation and hydropower in the Sudanese portion of the Blue Nile. Hydrologic inputs are combined with agronomic and economic inputs to formulate an optimization model within the General Algebraic Modeling System (GAMS). A sensitivity analysis is performed by testing model response to a range of economic conditions and to changes in the volume and timing of hydrologic flows. Results indicate that changing hydroclimate inputs have the capacity to greatly influence the productivity of Sudan's water resource infrastructure. Results also show that the economically optimal volume of water consumption, and thus the importance of existing treaty constraints, is sensitive to the perceived value of agriculture relative to electricity as well as to changing hydrological conditions.

    2007-03-01

    The signing of the Comprehensive Peace Agreement (CPA) in Sudan has created a new opportunity for peace. Approaches to food security must now be reoriented based on the agro-ecological diversity in Sudan. WFP is in a unique position to catalyse an approach to food security that meets immediate needs and contributes to long-term recovery, in collaboration with the Government of National Unity (GNU) and the Government of South Sudan (GOSS). Aggregate food production in Sudan has increased in the past decade. At sub-regional levels, however, many areas remain food insecure. Major research must be undertaken to identify optimum levels of food production and barriers to access to food at sub-regional levels as a first step towards linking deficit areas with areas of surplus. Initiatives must also be undertaken to facilitate increased integration between sub-regions. Increased sub-regional linkages could ensure more efficient delivery of food in the short term as well as recovery and economic growth in the long term. PMID:17349002

    Full Text Available To explore the expected role of Bovine Viral Diarrhea Virus (BVDV in pneumonia in cattle, cattle lungs (n=242 showing signs of pneumonia were collected from slaughter houses of three different localities located at Northern, Central and Western Sudan during 2010–2013. The collected samples were tested for the presence of BVDV antigen using Enzyme-Linked Immunosorbent Assay (ELISA, and Fluorescent Antibody Test (FAT. Twenty six (10.7% out of 242 samples were found to be positive for BVDV. Positive results were seen in all the three studied areas, with the highest prevalence (16.7%; n=4/24 at Gezira State in Central Sudan. BVDV genome could be detected in all ELISA positive samples. The results indicated the existence of BVDV infection in cattle in different areas in Sudan, and its possible association with respiratory infections in cattle. Analysis using BLAST indicated that the sequence was identical to the previously reported BVDV-1 (GenBank accession AF220247.1.; nucleotide A was found in our study at position 9 of our sequence, whereas T was present instead in the reference virus. This is the first report of detecting BVDV antigen, genome, and its sequence analysis collected from cattle lungs in Sudan.

  19. Modulatory effects of rutin on biochemical and hematological parameters in hypercholesterolemic Golden Syrian hamsters

    Directory of Open Access Journals (Sweden)

    Alexandre Kanashiro

    2009-03-01

    Full Text Available Flavonoids have been reported to exhibit several pharmacological properties, mainly in cardiovascular and inflammatory diseases. In the present study, we observed that rutin, a known glycosylated flavonoid isolated from Dimorphandra mollis, had a lowering effect on plasma triglyceride levels of diet-induced hypercholesterolemic Golden Syrian hamsters, but did not change total cholesterol and high-density lipoprotein cholesterol levels. Moreover, high-fat or rutin supplemented diets showed no immunotoxic effects, since no significant changes were observed on total white blood cells, granulocytes and mononuclear cells, as well as on the neutrophil apoptosis degree, when compared to untreated animals. Therefore, rutin seems to be a selective and non-toxic modulator of hypercholesterolemia, which can be promising for the development of new drugs.Os flavonóides possuem diversas propriedades farmacológicas, principalmente nas doenças cardiovasculares e inflamatórias. No presente estudo, observamos que a rutina, um conhecido flavonóide glicosilado isolado da Dimorphandra mollis, diminuiu o nível de triglicerídeos plasmáticos em hamsters Golden Syrian hipercolesterolêmicos sem alterar os níveis de colesterol total e colesterol HDL. Além disso, observamos que dietas hipercolesterolêmicas ou suplementadas com rutina não apresentaram efeito imunotóxico, uma vez que nenhuma alteração significativa foi observada nos leucócitos totais, granulócitos e células mononucleares, bem como no grau de neutrófilos em apoptose, quando comparado com animais não tratados. Portanto, a rutina parece ser um modulador seletivo e não tóxico da hipercolesterolemia, o que pode ser promissor para o desenvolvimento de novos fármacos.

  20. Facilitation of male sexual behavior in Syrian hamsters by the combined action of dihydrotestosterone and testosterone.

    Directory of Open Access Journals (Sweden)

    David J Piekarski

    Full Text Available BACKGROUND: Testosterone (T controls male Syrian hamster sexual behavior, however, neither of T's primary metabolites, dihydrotestosterone (DHT and estradiol (E(2, even in highly supraphysiological doses, fully restores sexual behavior in castrated hamsters. DHT and T apparently interact with androgen receptors differentially to control male sexual behavior (MSB, but whether these two hormones act synergistically or antagonistically to control MSB has received scant experimental attention and is addressed in the present study. METHODOLOGY/PRINCIPAL FINDINGS: Sexually experienced male Syrian hamsters were gonadectomized and monitored 5 weeks later to confirm elimination of the ejaculatory reflex (week 0, at which time they received subcutaneous DHT-filled or empty capsules that remained in situ for the duration of the experiment. Daily injections of a physiological dose of 25 µg T or vehicle commenced two weeks after capsule implantation. MSB was tested 2, 4 and 5 weeks after T treatment began. DHT capsules were no more effective than control treatment for long-term restoration of ejaculation. Combined DHT + T treatment, however, restored the ejaculatory reflex more effectively than T alone, as evidenced by more rapid recovery of ejaculatory behavior, shorter ejaculation latencies, and a greater number of ejaculations in 30 minute tests. CONCLUSIONS/SIGNIFICANCE: DHT and T administered together restored sexual behavior to pre-castration levels more rapidly than did T alone, whereas DHT and vehicle were largely ineffective. The additive actions of DHT and T on MSB are discussed in relation to different effects of these androgens on androgen receptors in the male hamster brain mating circuit.

  1. Determination of polonium 210 in different types of tobacco consumed in Sudan

    International Nuclear Information System (INIS)

    The carcinogenic effect of 210 Po with respect to lung cancer is an important problem in many countries with very high cigarette consumption. Sudan is one of the consumptions of cigarettes in the world. The aim of this study was the determination polonium-210 in different parts of tobacco plant comes from China and Brazil consumed in cigarette in Sudan and determination of 210 Po in five most frequently smoked brands more consumption in Sudan. The annual committed effective dose from cigarette was determined and comparison with other results reported in literature. The tobacco plant (leaves and root) for analysis were collected from Haggar factory in Sudan and another brand were collected randomly from markets, only the most popular one was chosen for analysis (Bringi, Lord, Winner, Goal, Benson). The polonium-210 activity was measured on an alpha-spectrometer equipped with semiconductor surface barrier silicon detectors after spontaneously plated onto asilver disc from hydrochloric acid medium. Polonium samples were measured for 2-3 days. The accuracy and precision of radiochemical method were evaluated using (IAEA-326). The values of activity concentration of 210 Po found in cigarettes consumed in Sudan are within of the range of values found in the literature. The 210 Po presented concentration in different brands ranging from 22.8 to 51.6 Bqkg-1(average 36.54 Bq kg-1). The activity concentration of 210 Po in popular brand cigarette tobacco is higher than that in fine brand cigarette tobacco. Found the highest concentration in the raw material compared to the final product is attributed that to the import, storage and manufacturing processes. Activity determination indicates those cigarettes consumed in Sudan are comparable to the values reported in China and Brazil that the raw material comes from these two countries. The polonium is non-uniformly distributed within the tobacco plants analyzed in this study, the highest levels were found in the leaves

  2. Demographic intermediation between development and population redistribution in Sudan.

    1983-12-01

    This article analyzes the causes of population distribution in various geographical regions of Sudan. Population distribution is a function of fertility, mortality, and net migration. These variables are primarily caused by changes in socioeconomic factors prevailing in each area. The analysis shows that the population distribution among the geographical regions is primarily shaped by the differential development actions during the last 2 decades. The regional variability of population growth and density largely reflects regional development. Provinces are classified into 3 groups according to stages of population growth. The 1st group is composed of the 3 southern provinces, characterized by the highest mortality, lowest fertility, a marginal volume of net migration, and the lowest overall population growth rate during the last 2 decades. These are the poorest provinces in terms of per capita income, education, communication, and health measures. The 2nd group comprises Dafur, Kordofan, Northern and Red Sea Provinces, which generally reflect an intermediate stage in the demographic evolution in the country. Fertility is positively correlated and mortality is inversely related to the level of per capita income, resulting in an inverse relationship between the 2 vital rates. Therefore, the natural growth will probably increase. However, there are also areas of out-migration. Their future population growth and density will depend on the extent to which the out-migration will affect their natural growth rates. The 3rd group is composed of Khartoum, Blue Nile and Kassala provinces. They have the highest fertility, lowest mortality and highest volume of in-migration. Therefore, they witnessed the highest population growth rate and population density during the period. They encompass the largest urban centers with the highest degree of modernization and family planning activities. It is postulated that their future fertility and mortality rates will decline in varying

    Structural and maturation studies in the northwest of the Muglad Basin, Sudan showed a thick sedimentary section up to 9000 m in the deep sub-basins and an average of about 6000 m in the Sharaf-Abu Gabra Ridge. The isopach map of the Lower Cretaceous Abu Gabra-Sharaf formations, which contain source rocks, showed a thickness of sedimentary section between 2000 and 5000 m. The burial history showed high subsidence rates during the first rifting phase with relatively low subsidence rates during the following two phases in this part of the basin. Significant erosion of the sedimentary section occurred in the ridge area during Miocene and Cenomanian-Albian times. The geothermal gradients in the modelled wells range between 18 and 27.5 °C/km corresponding to the relatively wide range of present day heat flow of between 37 and 63 mW/m 2, averaging 50 mW/m 2. Heat flow history curves consistent with vitrinite reflectance data were adopted with elevated high heat flow (75 mW/m 2) during the first rifting phase followed by minor peaks (average 60 mW/m 2) during the second and the third rifting phases. Application of a kinetic vitrinite maturation model resulted in a present day oil window between 2000 and 4500 m. The source rock of the Abu Gabra (AG) and Sharaf (SH) formations, which has an average total organic carbon of 1.0% and hydrogen index (HI) of 280, was modelled for hydrocarbon generation. The section was divided into four layers; AG-1 (Albian), AG-2 (Aptian), SH-1 (Barremian) and SH-2 (Neocomian). Conditions for hydrocarbon generation are present throughout the Sharaf formation and in AG-2. The generation model suggests an average generation amount of 4 mgHC/g rock in the lower three modelled layers with a timing range between 120 Ma and the present. Total calculated oil volume is about 370 US billion bbls and the expected volume expelled and migrated (40%) is 150 US billion bbls. The total gas expelled and migrated (90%) is 1600 US trillion cu ft. Retention of

    Full Text Available To characterize hepatitis C virus (HCV epidemiology and assess country-specific population-level HCV prevalence in four countries in the Middle East and North Africa (MENA region: Djibouti, Somalia, Sudan, and Yemen.Reports of HCV prevalence were systematically reviewed as per PRISMA guidelines. Pooled HCV prevalence estimates in different risk populations were conducted when the number of measures per risk category was at least five.We identified 101 prevalence estimates. Pooled HCV antibody prevalence in the general population in Somalia, Sudan and Yemen was 0.9% (95% confidence interval [95%CI]: 0.3%-1.9%, 1.0% (95%CI: 0.3%-1.9% and 1.9% (95%CI: 1.4%-2.6%, respectively. The only general population study from Djibouti reported a prevalence of 0.3% (CI: 0.2%-0.4% in blood donors. In high-risk populations (e.g., haemodialysis and haemophilia patients, pooled HCV prevalence was 17.3% (95%CI: 8.6%-28.2% in Sudan. In Yemen, three studies of haemodialysis patients reported HCV prevalence between 40.0%-62.7%. In intermediate-risk populations (e.g.. healthcare workers, in patients and men who have sex with men, pooled HCV prevalence was 1.7% (95%CI: 0.0%-4.9% in Somalia and 0.6% (95%CI: 0.4%-0.8% in Sudan.National HCV prevalence in Yemen appears to be higher than in Djibouti, Somalia, and Sudan as well as most other MENA countries; but otherwise prevalence levels in this subregion are comparable to global levels. The high HCV prevalence in patients who have undergone clinical care appears to reflect ongoing transmission in clinical settings. HCV prevalence in people who inject drugs remains unknown.

  15. Lactase persistence variants in Arabia and in the African Arabs.

    Science.gov (United States)

    Priehodová, Edita; Abdelsawy, Abdelhay; Heyer, Evelyne; Cerný, Viktor

    2014-01-01

    Lactase persistence (LP), the state enabling the digestion of milk sugar in adulthood, occurs only in some human populations. The convergent and independent origin of this physiological ability in Europe and Africa is linked with animal domestication that either had started in both places independently or had spread from the Near East by acculturation. However, it has recently been shown that at least in its southern parts, the population of Arabia not only has a different LP-associated mutation profile than the rest of Africa and Europe but also had experienced an independent demographic expansion occurring before the Neolithic around the Pleistocene-Holocene boundary. In Arabia, LP is associated with mutation -13,915*G and not, as in Europe, with -13,910*T or, as in Africa, with -13,907*G and -14,010*C. We show here that, in Arabia, -13,915*G frequency conforms to a partial clinal pattern and that this specific mutation has likely been spread from Arabia to Africa only recently from the sixth century AD onward by nomadic Arabs (Bedouins) looking for new pastures. Arabic populations in Africa that still maintain a nomadic way of life also have more -13,915*G variants and fewer sub-Saharan L-type mitochondrial DNA haplogroups; this observation matches archaeological and historical records suggesting that the migration of Arabic pastoralists was accompanied by gradual sedentarization that allowed for admixture with the local African population.

    At the crossroads between Africa and Eurasia, Arabia is necessarily a melting pot, its peoples enriched by successive gene flow over the generations. Estimating the timing and impact of these multiple migrations are important steps in reconstructing the key demographic events in the human history. However, current methods based on genome-wide information identify admixture events inefficiently, tending to estimate only the more recent ages, as here in the case of admixture events across the Red Sea (~8-37 generations for African input into Arabia, and 30-90 generations for "back-to-Africa" migrations). An mtDNA-based founder analysis, corroborated by detailed analysis of the whole-mtDNA genome, affords an alternative means by which to identify, date and quantify multiple migration events at greater time depths, across the full range of modern human history, albeit for the maternal line of descent only. In Arabia, this approach enables us to infer several major pulses of dispersal between the Near East and Arabia, most likely via the Gulf corridor. Although some relict lineages survive in Arabia from the time of the out-of-Africa dispersal, 60 ka, the major episodes in the peopling of the Peninsula took place from north to south in the Late Glacial and, to a lesser extent, the immediate post-glacial/Neolithic. Exchanges across the Red Sea were mainly due to the Arab slave trade and maritime dominance (from ~2.5 ka to very recent times), but had already begun by the early Holocene, fuelled by the establishment of maritime networks since ~8 ka. The main "back-to-Africa" migrations, again undetected by genome-wide dating analyses, occurred in the Late Glacial period for introductions into eastern Africa, whilst the Neolithic was more significant for migrations towards North Africa.

    2014-01-01

    Sudan I [1-(phenylazo)-2-naphthol, C.I. Solvent Yellow 14] is an industrial dye, which was found as a contaminant in numerous foods in several European countries. Because Sudan I has been assigned by the IARC as a Category 3 carcinogen, the European Union decreed that it cannot be utilized as food colorant in any European country. Sudan I induces the malignancies in liver and urinary bladder of rats and mice. This carcinogen has also been found to be a potent mutagen, contact allergen and sensitizer, and exhibits clastogenic properties. The oxidation of Sudan I increases its toxic effects and leads to covalent adducts in DNA. Identification of enzymatic systems that contribute to Sudan I oxidative metabolism to reactive intermediates generating such covalent DNA adducts on the one hand, and to the detoxification of this carcinogen on the other, is necessary to evaluate susceptibility to this toxicant. This review summarizes the identification of such enzymes and the molecular mechanisms of oxidation reactions elucidated to date. Human and animal cytochrome P450 (CYP) and peroxidases are capable of oxidizing Sudan I. Of the CYP enzymes, CYP1A1 is most important both in Sudan I detoxification and its bio-activation. Ring-hydroxylated metabolites and a dimer of this carcinogen were found as detoxification products of Sudan I generated with CYPs and peroxidases, respectively. Oxidative bio-activation of this azo dye catalyzed by CYPs and peroxidases leads to generation of proximate genotoxic metabolites (the CYP-catalyzed formation of the benzenediazonium cation and the peroxidase-mediated generation of one-electron oxidation products), which covalently modify DNA both in vitro and in vivo. The predominant DNA adduct generated with the benzenediazonium cation was characterized to be 8-(phenylazo)guanine. The Sudan I radical species mediated by peroxidases reacts with the -NH2 group in (deoxy)guanosine, generating the 4-[(deoxy)guanosin-N(2)-yl]Sudan I product. Sudan I

    Since 2013, four hospitals in northern Israel have been providing care for Syrian nationals, primarily those wounded in the ongoing civil war. We analyzed carbapenemase-producing Enterobacteriaceae (CPE) isolates obtained from these patients. Isolate identification was performed using the VITEK 2 system. Polymerase chain reaction (PCR) was performed for the presence of bla KPC, bla NDM, and bla OXA-48. Susceptibility testing and genotyping were performed on selected isolates. During the study period, 595 Syrian patients were hospitalized, most of them young men. Thirty-two confirmed CPE isolates were grown from cultures taken from 30 patients. All but five isolates were identified as Klebsiella pneumoniae and Escherichia coli. Nineteen isolates produced NDM and 13 produced OXA-48. Among a further 29 isolates tested, multilocus sequence typing (MLST) showed that ST278 and ST38 were the major sequence types among the NDM-producing K. pneumoniae and OXA-48-producing E. coli isolates, respectively. Most were resistant to all three carbapenems in use in Israel and to gentamicin, but susceptible to colistin and fosfomycin. The source for bacterial acquisition could not be determined; however, some patients admitted to different medical centers were found to carry the same sequence type. CPE containing bla NDM and bla OXA-48 were prevalent among Syrian wounded hospitalized patients in northern Israel. The finding of the same sequence type among patients at different medical centers implies a common, prehospital source for these patients. These findings have implications for public health throughout the region. PMID:26581423

  13. Trace elements determination in Syrian honey using x-ray fluorescence technique

    International Nuclear Information System (INIS)

    Major and trace elements of S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Rb, Sr in 27 Syrian honey samples, which collected from different areas in the country, in addition to 3 imported honey samples, were determined by dry ashing method for XRF analysis. The samples were diluted and homogenized with a binder made from cellulose powder. The analyzed elements were divided into three groups, relating to the secondary targets used for X-ray excitation. The internal standard method for XRF analysis with a Mo secondary target was used for the determination of the first group of elements: Sr, Rb, Se, As, Zn, Cu, Ni, and Fe. While, the external standard method for XRF analysis with Cu and Ti secondary targets was used for the determination of the second: Mn, Cr, Ti, Ca, K, and third: Cl, and S group of elements, respectively. The results were accurate with a relative standard error less than 4.2 %. The problem of element loss was overcome by the complete drying of honey samples before their ashing. The moisture content was obtained using mass loss and refractive index methods. As a result, the lower limits of detection (LLD) obtained by Mo-XRF was in the range from 0.011 μg Sr/g to 0.064 μg Fe/g, resulting for samples containing 0.1 % ash and collecting live time 1000 s; while, LLD obtained by Cu-XRF was in the range 0.014 μg Mn/g to 0.057 μg K/g. LLD for S and Cl using Ti secondary target was with values of 0.503 μg/g and 1.96 μg/g, respectively. The enhancement factor obtained by drying method for XRF was in the range from 147 to 1667. Normal concentration of elements in Syrian honey was obtained. The concentration of elements was comparable to those obtained by other workers for honeys in different countries. Elements of K, Ca, and Cl were predominantly distributed in all Syrian honey samples. Elements of Sr, Zn, Cu, Fe, Ti, and S were well distributed in all honey samples. While, the concentrations of Rb, Ni, Mn, Cr elements in some honey samples were below the

These dyes have been illegally used as food additives in products such as chilli spices and palm oil to enhance their red colour. From 2003 to 2005, the European Union made a series of decisions requiring chilli spices and palm oil imported to the European Union to contain analytical reports declaring them free of Sudan I-IV. In order for the USFDA to investigate the adulteration of palm oil and chilli spices with unapproved colour additives in the United States, a method was developed for the extraction and analysis of Sudan dyes in palm oil, and previous methods were validated for Sudan dyes in chilli spices. Both LC-DAD and LC-MS/MS methods were examined for their limitations and effectiveness in identifying adulterated samples. Method validation was performed for both chilli spices and palm oil by spiking samples known to be free of Sudan dyes at concentrations close to the limit of detection. Reproducibility, matrix effects, and selectivity of the method were also investigated. Additionally, for the first time a survey of palm oil and chilli spices was performed in the United States, specifically in the Washington, DC, area. Illegal dyes, primarily Sudan IV, were detected in palm oil at concentrations from 150 to 24 000 ng ml(-1). Low concentrations (adulteration. PMID:26824489

    Highlights: • A lipophilic sensor layer was applied to enzymatically grown SERS substrates. • Sudan III molecules could be detected in presence of water-insoluble competitors. • The carcinogenic food dye Sudan III was detected in a relevant concentration range. • Multivariate statistics allows quantitative measurements of Sudan III. • Sudan III contaminations were successfully detected out of spiked paprika powder. - Abstract: Food safety is a topic of great importance for our society which places high demands on analytical methods. Surface enhanced Raman spectroscopy (SERS) meets the requirements for a rapid, sensitive and specific detection technique. The fact that metallic colloids, one of the most often used SERS substrates, are usually prepared in aqueous solution makes the detection of water-insoluble substances challenging. In this paper we present a SERS based approach for the detection of water-insoluble molecules by applying a hydrophobic surface modification onto the surface of enzymatic generated silver nanoparticles. By this approach the detection of the illegal water-insoluble food dyes, such as Sudan III in presence of riboflavin, as water-soluble competitor, is possible.

  18. Human security in Sudan: The report of a Canadian Assessment Mission

    International Nuclear Information System (INIS)

    In October 1999 the Minister of Foreign Affairs and the Minister for International Co-operation announced the creation of an assessment mission to Sudan to examine allegations about human rights abuses, including the practice of slavery and to investigate and report on alleged link between oil development and human rights violations, particularly in respect of the forced removal of populations around oil fields and oil-related developments. The investigation was the result of allegations concerning the forced relocation of civilian populations in the vicinity of the oil field in the interest of a more secure environment for oil extraction by the Government of Sudan and its partners, which include Talisman Energy Inc., a Canadian oil company. In creating the Mission, the Department of Foreign Affairs declared that if it became evident that oil extraction is exacerbating the conflict in Sudan, or the the human rights violations, the Government of Canada may consider applying economic and trade sanctions. This report contains the results of the Mission's observations and meetings with members of the Government of Sudan, opposition leaders, human rights, civil society, and diplomatic representatives, as well as displaced Southern Sudanese and the UN officials trying to help them. The Mission also thoroughly examined Talisman Energy Inc.'s operations in Sudan and the extent to which oil extraction is exacerbating conflict in that country. The overall conclusion of the Mission's investigation is that while the on-going civil war in Sudan is not about oil, oil has become a key factor, and it is exacerbating the conflict. With regard to the role of Talisman, the conclusion was that the company did not do all that it could to keep itself fully informed as to what was happening, and while some progress has been made in curbing human rights violations, the oil operations in which Talisman is involved add to the conflict and suffering.

    The suprachiasmatic nucleus (SCN) generates circadian rhythms of behavior and hormone secretion in mammals, and integrates responses to light and nonphotic stimuli to synchronize such rhythms with the external environment. Previous studies have demonstrated a close association between the induction of the immediate early gene (IEG) c-fos in the SCN by light and phase shifts of circadian rhythms induced by light, but nonphotic stimuli (e.g., arousal), which also cause phase shifts, do not increase c-fos expression in the SCN. Because c-fos is now known to be a member of a large family of IEGs which can regulate transcription and thus cellular function, the aim of the current study was to determine whether induction of another member of this immediate early gene family, fosB, is associated with photic and nonphotic phase shifts. An antiserum that recognizes a unique peptide sequence derived from FosB was produced so that the expression of fosB could be investigated in cells within the SCN by immunocytochemical detection of its protein product. The regional distribution of FosB-immunoreactive (ir) cells in the SCN of Syrian and Siberian hamsters was broadly similar to that for c-Fos-ir cells. However, whereas c-fos expression in the SCN was constitutively low, but could be massively induced by light at particular circadian phases, FosB-ir cells were present at all circadian phases studied, irrespective of photic stimulation, and light only produced marginal increases in the number of FosB-ir cells compared with nonstimulated controls. Moreover, blockade of glutamatergic neurotransmission by pretreatment of hamsters with the NMDA receptor antagonist MK801 significantly reduced photic induction of c-Fos-ir cells, but did not influence the number of FosB-ir cells in the SCN. Finally, an arousing nonphotic stimulus known to cause phase advances in wheel-running behavior in Syrian hamsters did not alter significantly the number of FosB-ir cells in the SCN. These

    Urethane is an anaesthetic agent with minimal cardiovascular and respiratory system depression with long-lasting (6-10h) effects. Its carcinogenic potential avoids it from veterinary use. Either, the knowledge of its effects over the circulating catecholamines (cortisone and corticosterone), with reflects in the muscles physiology, it is widely used in pharmacological studies in laboratory species. At the first minutes, Urethane induces a hyperglycaemia condition due the insulin concentration decrease, later than, the insulin concentration and the condition becomes in hypoglycaemia, but the Urethane interfering in the urine production mechanisms has not been described. It is accepted that the glycolic level would not interferes in the kidney function, except in chronic states, notably associated with insulin related diseases. The relative high biological half-life of 177Lu-Dotatate allows its use in biodistribution studies among small animals whose metabolic rates are so fast that would be impossible observe them with the most part of the labeled molecules. During the performance of a cross-species extrapolation study using Urethane as anaesthesia and 177Lu-Dotatate as metabolic tracer, was observed the Urethane influence over urine formation in Swiss rats and Syrian hamster (Mesocricetus auratus). The objective of this work is only describes the Urethane action over the urine production.

    Full Text Available Most of the researches on peace agreements conclude that powersharing arrangements included in these are mostly to the detriment of longterm democratic transformation. The basic argument of these studies is that peace deals consolidate mainly the power of the signatories to the detriment of other major political forces. This article illustrates that, in contrast to many cases, the Comprehensive Peace Agreement (CPA, which was signed in 2005 between the government of Sudan represented by the ruling party, the National Congress Party (NCP and the Sudan People’s Liberation Movement/Army (SPLM/A, has led to an important political transformation in state structure as well as in power relations. Although the CPA enhanced the legitimacy of the SPLM and the NCP and consolidated their political domination, it, nevertheless, contributed to a significant political opening for other political forces in the North and in the South. The CPA put an end to the historically exclusive political hegemony of the North. This article focuses on the dynamics of relations between the SPLM and the NCP during the transitional period and illustrates how these dynamics have impacted upon the process of political transformation. Untersuchungen zu Friedensvereinbarungen kommen zumeist zu dem Schluss, dass die enthaltenen Machtteilungsklauseln einer langfristigen demokratischen Transformation abträglich sind. Als wichtigstes Argument wird dabei angeführt, dass Friedensvereinbarungen vor allem die Position der unterzeichnenden Partner stärken – zum Schaden anderer bedeutender politischer Kräfte. Der vorliegende Beitrag zeigt auf, dass – im Gegensatz zu vielen anderen Fällen – das Umfassende Friedensabkommen (Comprehensive Peace Agreement, CPA, das 2005 von der Regierung des Sudan, repräsentiert durch die Regierungspartei National Congress Party (NCP und die Sudan People’s Liberation Movement/Army (SPLM/A, unterzeichnet wurde, zu einem erheblichen Wandel sowohl

  17. Climate change, conflict and development in Sudan: global neo-Malthusian narratives and local power struggles.

    Science.gov (United States)

    Verhoeven, Harry

    2011-01-01

    Dystopian accounts of climate change posit that it will lead to more conflict, causing state failure and mass population movements. Yet these narratives are both theoretically and empirically problematic: the conflict–environment hypothesis merges a global securitization agenda with local manipulations of Northern fears about the state of planetary ecology. Sudan has experienced how damaging this fusion of wishful thinking, power politics and top-down development can be. In the 1970s, global resource scarcity concerns were used locally to impose the fata morgana of Sudan as an Arab-African breadbasket: in the name of development, violent evictions of local communities contributed to Sudan's second civil war and associated famines. Today, Darfur has been labelled ‘the world's first climate change conflict’, masking the long-term political-economic dynamics and Sudanese agency underpinning the crisis. Simultaneously, the global food crisis is instrumentalized to launch a dam programme and agricultural revival that claim to be African answers to resource scarcity. The winners, however, are Sudan's globalized Islamist elites and foreign investors, whilst the livelihoods of local communities are undermined. Important links exist between climatic developments and security, but global Malthusian narratives about state failure and conflict are dangerously susceptible to manipulations by national elites; the practical outcomes decrease rather than increase human security. In the climate change era, the breakdown of institutions and associated violence is often not an unfortunate failure of the old system due to environmental shock, but a strategy of elites in wider processes of power and wealth accumulation and contestation.

    Twenty-two commonly used pesticides were monitored during autumn, winter, and summer of 2004-2005 in 27 water samples from three sites along the White Nile in Sudan (former Sudan). Sites were selected to reflect pesticides gathered from drainage canals in central Sudan and from upstream sources. Collected samples were extracted and subjected to gas chromatographic analysis. Pesticides levels were measured in nanograms per liter. Pesticides residues were detected in 96 % of the samples with a total residue burden of 4132.6 ng L(-1), and an overall mean concentration and range of 50.99 and not detected-1570 ng L(-1), respectively. Ororganochlorines were the most frequently detected contaminants, which were found in 70 % of the samples, causing a total burden of 2852.8 ng L(-1), followed by pyrethroids 15 % of the samples, with a total burden of 926.5 ng L(-1). The tested herbicides were detected in ˂4 % of the samples with a total burden of 353.3 ng L(-1), while organophosphorus levels were below the detection limit. The most frequent contaminants were the following: heptachlor and its epoxide (52 % of samples), followed by DDTs (dichlorodiphenyltrichloroethanes) (DDT and DDE, in 19 % of the samples), cypermethrin and fenvalerate (in 11 % of the samples), and pendimethalin (in oxyfluorfen were not detected in the analyzed samples. Generally, levels were least in autumn, and followed by summer and winter. Sources of contamination might include agricultural lands in central Sudan and upstream sources. Both recent and old contaminations were indicated. PMID:27230426

    Full Text Available Sudan is one of the largest African countries, covering an area of 1.9 million km2—approximately one fifth of the geographic area of the United States. The population is 30 million people, the majority of whom (68% live in rural areas, as compared with the sub-Saharan African average of approximately 62%. Sudan is considered a lower-middle income country—with 47% of the population living below the poverty line and a gross domestic product (GDP of US $62 billion in 2010. In addition to excessive burden of communicable diseases such as malaria, tuberculosis, and schistosomiasis, Sudan is particularly susceptible to both natural and manmade disasters. Drought and flood are quite common due to Sudan’s proximity to and dependency on the Nile, and throughout history Sudan has also been plagued with internal conflicts and outbreaks of violence, which bring about a burden of traumatic disease and demand high quality emergency care. The purpose of this paper is to describe the state of emergency care and Emergency Medicine education, and their context within the Sudanese health care system. As is the case in most African countries, emergency care is delivered by junior staff: new graduates from medical schools and unsupervised medical officers who handle all types of case presentations. In 2001, increased mortality and morbidity among unsorted patients prompted the Ministry of Health to introduce a new triage-based emergency care system. In late 2005, twenty-one Emergency physicians delivered these new Emergency Services. In 2011, following a curriculum workshop in November 2010, the Emergency Medicine residency program was started in Khartoum. Currently there are 27 rotating registrars, the first class of whom is expected to graduate in 2015.

    Food security status is determined by the combination of aggregate food availability, household food access and utilization. In Sudan, given climate extremes and insecurity, food availability is a crucial component of household food security status. Communities that rely on raising livestock are most vulnerable to hunger when drought or other disaster strikes. The general objective of this study was to assess the role of livestock production on food security in the White Nile State. Specifica...

  6. Climate change, conflict and development in Sudan: global neo-Malthusian narratives and local power struggles.

    Science.gov (United States)

    Verhoeven, Harry

    2011-01-01

    Dystopian accounts of climate change posit that it will lead to more conflict, causing state failure and mass population movements. Yet these narratives are both theoretically and empirically problematic: the conflict–environment hypothesis merges a global securitization agenda with local manipulations of Northern fears about the state of planetary ecology. Sudan has experienced how damaging this fusion of wishful thinking, power politics and top-down development can be. In the 1970s, global resource scarcity concerns were used locally to impose the fata morgana of Sudan as an Arab-African breadbasket: in the name of development, violent evictions of local communities contributed to Sudan's second civil war and associated famines. Today, Darfur has been labelled ‘the world's first climate change conflict’, masking the long-term political-economic dynamics and Sudanese agency underpinning the crisis. Simultaneously, the global food crisis is instrumentalized to launch a dam programme and agricultural revival that claim to be African answers to resource scarcity. The winners, however, are Sudan's globalized Islamist elites and foreign investors, whilst the livelihoods of local communities are undermined. Important links exist between climatic developments and security, but global Malthusian narratives about state failure and conflict are dangerously susceptible to manipulations by national elites; the practical outcomes decrease rather than increase human security. In the climate change era, the breakdown of institutions and associated violence is often not an unfortunate failure of the old system due to environmental shock, but a strategy of elites in wider processes of power and wealth accumulation and contestation.

The General Administration of Mental Health and Social Services of the Ministry of Health over the past 4 years has sought to streamline the delivery of mental health care services to health consumers in Saudi Arabia. Objective: We overview here the outcome of a survey that assessed the Saudi MHS and suggest strategic steps for its further improvement. Method: The World Health Organization Assessment Instrument for Mental Health Systems was used systematically to collect information on the Saudi MHS in 2009–2010, 4 years after a baseline assessment. Results: Several mental health care milestones, especially provision of inpatient mental health services supported by a ratified Mental Health Act, were achieved during this period. However, community mental health care services are needed to match international trends evident in developed countries. Similarly, a larger well-trained mental health workforce is needed at all levels to meet the ever-increasing demand of Saudi society. Conclusion: This updated MHS information, discussed in light of international data, will help guide further development of the MHS in Saudi Arabia in the future, and other countries in the Eastern Mediterranean region may also benefit from Saudi experience.

    2011-07-01

    Full Text Available The aim of this study was to evaluate the current and potential values and identify main threatening factors of Balanites aegyptiaca in Sudan. Three areas were selected for data collection (Umm Abdalla, Boat and Id Elfrissan. Group discussion was carried out to tap local community knowledge about the species uses, potentials and threatening factors. Then structured interview was used to verify and check the information generated in group discussion. A total of 120 respondents from the three areas were interviewed. Results showed that Hegleig tree is very important multi-purpose tree for livelihood of local communities in many areas of the Sudan. The gene pool of the species was severely affected by many deteriorating factors like lopping of branches, grazing, mechanized farming and gap in transfer of indigenous knowledge. These factors were combined with removal of associated trees and retaining Balanites which made it vulnerable. Protection, in situ conservation stands and conservation in use is the most suitable measures for this species in Sudan.

  3. Depletion of forest resources in Sudan: Intervention options for optimal control

    International Nuclear Information System (INIS)

    Agricultural expansion and over-cutting of trees for fuelwood are important causes of deforestation in arid and semi-arid countries such as Sudan. The consequence is increased desertification and high erosion and loss of soil nutrients leading to declining agricultural productivity. However, the social costs of the deforestation externality are not taken into account in present forest management and land use planning in Sudan leading to under-pricing and over-exploitation of the country's forest resources. This study evaluated the suitability of approaches commonly used by most forest resource management agencies for prediction of the state and control of harvesting of forest resources against alternative empirical simulation models using relevant information about economic behaviour of trading agents in the fuelwood market. Results showed the clear superiority of models integrating market behaviour over current approaches in the ability to better simulate real trends of wood consumption and hence depletion rates. The study also adopted an optimal control model to derive socially optimal forest harvesting regimes. The results showed that current rates of forest resource rent recovery and reforestation efforts are very far from optimal. Results also suggest that, in addition to optimal pricing and higher reforestation efforts, promotion and availability of fuel substitutes and investment in wood energy conversion efficiencies have a strong potential for curbing the problem of deforestation in Sudan

    A reverse transcription-polymerase chain reaction (RT-PCR) was used to amplify 1412 bp of the fusion protein gene (F gene) of four Newcastle disease virus (NDV) isolates; two velogenic (TY-1/90 and DIK-90) and two lentogenic isolates (Dongla 88/1 and GD.S.1). Following sequencing, nucleotide sequences were annotated and 894 bp were compared phylogenetically with those from strains previously reported in the Sudan and the virus strains published on the GenBank. It could be demonstrated that TY-1/90 and DIK-90 strains belong to the genotype VI of NDV and are in close genetic relationship to sub- genotype VIb. TY-1/90 and DIK-90 strains were observed to be genetically unrelated to the earlier Sudanese isolates of 1970/80s and the late of 2000s suggesting a different origin. The close genetic relationship to the European and African pigeon paramyxovirus type 1 (PPMV-1) suggests a common ancestor. Dongola, GD.S.1 strains were classified into genotype II that comprises non-pathogenic lentogenic NDV strains. The present genetic classification of NDV isolates of the Sudan provides valuable information on genotypes of NDV. Further molecular epidemiological investigations of the recent outbreaks of Newcastle disease in the Sudan are needed in order to improve the efficiency of control strategies and vaccine development.

    1983-06-01

    In 1977 the Government of the Sudan adopted a Plan with the long-term aim of universalizing primary education by the end of 1990. In spite of real accomplishments in education since the launching of the UPE scheme, there is a widespread conviction that the attainment of this objective will be delayed far beyond 1990 unless serious measures are taken to modify existing trends and imbalances. The following article, based on available information from the Sudan and on a microplanning study undertaken jointly by IIEP and the Sudanese Ministry of Education in 1981, is an attempt to draw some lessons from the Sudanese experience of UPE, highlighting the major difficulties encountered in implementing this policy and raising some of the implications of such a scheme for planning methods and perspectives. Although a host of financial and material problems (lack of resources, problems of communication, etc.) may be pointed out, one must not forget the pressure of existing trends and imbalances such as the `upward thrust' in the development of the Sudanese school system, which contrasts with the top priority accorded in theory to primary education. The existing planning methods laid down by the central level and formed within a uniform and general setting, scarcely suit the variety of local situations in a country like the Sudan where the different regions are very diverse in their geographic, economic, ethnic and political composition.

    Full Text Available Water rather than land is the limiting factor for crop production in Sudan. This study attempts to use the water footprint (WFP and virtual water concepts to account for crops water consumption under the Sudanese rainfed and irrigated conditions. The general average of the green WFP of sorghum and millet were found to be about 7700 and 10700 m3 ton-1, respectively. According to experimental results at three different climates, in-situ rainwater harvesting techniques could reduce the WFP of rainfed sorghum by 56% on the average. The blue component (surface water shows the highest contribution to the total WFP of irrigated crops: 88% for cotton, 70% for sorghum, 68% for groundnut and 100% for wheat. However, the role of the green water (rainwater is not marginal since it largely influences the operation and maintenance (silt clearance of the gravity-fed irrigation system. Under normal conditions, the annual total virtual water demand of sorghum (the dominant food crop in Sudan is found to be 15 km3, of which 91% is green water. During a dry year, however, Sudan could experience a deficit of 2.3 km3 of water, necessitating the adoption of a wise food stocking-exporting policy.

    Full Text Available BACKGROUND: wars and its challenges have historically afflicted humanity. In Syria, severe injuries occurred due to firearms and explosives used in the war between government forces and civilians for a period of over 2 years. MATERIALS AND METHODS: the study included 364 cases, who were admitted to Mustafa Kemal University Hospital, Medicine School (Hatay, Turkey, and underwent surgery. Survivors and non-survivors were compared regarding injury site, injury type and number of transfusions given. The mortality rate found in this study was also compared to those reported in other civil wars. RESULTS: the mean age was 29 (3-68 years. Major sites of injury included extremities (56.0%, head (20.1%, abdomen (16.2%, vascular structures (4.4% and thorax (3.3%. Injury types included firearm injury (64.4%, blast injury (34.4% and miscellaneous injuries (1.2%. Survival rate was 89.6% while mortality rate was 10.4%. A significant difference was observed between mortality rates in this study and those reported for the Bosnia and Lebanon civil wars; and the difference became extremely prominent when compared to mortality rates reported for Vietnam and Afghanistan civil wars. CONCLUSION: among injuries related to war, the highest rate of mortality was observed in head-neck, abdomen and vascular injuries. We believe that the higher mortality rate in the Syrian Civil War, compared to the Bosnia, Vietnam, Lebanon and Afghanistan wars, is due to seeing civilians as a direct target during war.

    The aim of the present investigations was to examine the effects of melatonin (Mel) on oxytocin (OT) release under conditions of osmotic stimulation, brought about by hypertonic saline administration, as well as to determine whether osmotically stimulated OT release in Mel-treated Syrian hamster is associated with alterations in the release of prolactin (PRL) and in norepinephrine (NE) and dopamine (DA) content in the hypothalamus. In both Mel- and vehicle-treated hamsters, injection of hypertonic saline was followed by a significant decrease in OT content in the pituitary neurointermediate lobe (NIL) and elevation of plasma OT and PRL levels. Melatonin injections had no significant affect on NIL OT content in either isotonic- or hypertonic-saline treated animals. Pretreatment with Mel did not alter plasma OT or PRL levels in isotonic saline-injected animals. However, Mel facilitated the release of OT, but prevented the release of PRL after hypertonic saline administration. Melatonin treatment reduced hypothalamic NE content (but not that of DA) in isotonic-saline treated animals. After osmotic stimulation, hypothalamic content of NE and DA was significantly lower in Mel-treated than in vehicle-treated animals. Data from the present study suggest that the osmotically-stimulated release of OT and PRL seems to be related to the activation of noradrenergic rather than dopaminergic transmission. Both dopaminergic and noradrenergic transmission may be, however, involved in mediating the effects of Mel on the osmotically-activated OT and PRL release. (author). 48 refs, 3 figs.

    In cases where different species might be housed in the same room or secondary enclosure, the Guide for the Care and Use of Laboratory Animals recommends that the animals should be behaviorally compatible and have the same health status. Syrian hamsters and Mongolian gerbils, both desert-dwelling rodents, appear to be reasonable candidates for such a combination. This study was undertaken to evaluate whether housing hamsters and gerbils in the same secondary enclosure is an acceptable practice. Weanling and breeding-age hamsters and gerbils were housed in open-topped cages in an isolator for 5 mo; the isolator also contained with nude and haired mice, which acted as sentinels. Cages housing hamsters and gerbils were rotated between species, and dirty bedding was exchanged between species in an effort to transmit microorganisms. In addition, sentinel mice housed in the isolator were supplied with dirty bedding from both hamsters and gerbils. Neither species showed clinical signs of illness, the health status of neither the hamsters nor the gerbils changed significantly, and the sentinel mice acquired only 2 infectious organisms, a Helicobacter species and Staphylococcus aureus. Both hamsters and gerbils bred successfully when housed together in the same isolator, and no infanticide or mortality was seen. Breeding performance did not differ between isolator breeding and barrier breeding. This study supports the housing of hamsters and gerbils in the same secondary enclosure. PMID:26045450

    Alcohol use disorder in patients with schizophrenia dramatically worsens their clinical course, and few treatment options are available. Clozapine appears to reduce alcohol use in these patients, but its toxicity limits its use. To create a safer clozapine-like drug, we tested whether the antipsychotic iloperidone, a drug that combines a weak dopamine D2 receptor blockade and a potent norepinephrine alpha-2 receptor blockade would reduce alcohol drinking, and whether its effect on alcohol drinking could be increased if combined with an agent to facilitate norepinephrine activity. Syrian golden hamsters (useful animal model for screening drugs that reduce alcohol drinking in patients with schizophrenia) were given free access to water and alcohol (15% v/v) until stable drinking was established. Animals (n = 6-7/group), matched according to alcohol intake, were treated daily with each drug (iloperidone; clozapine; haloperidol; desipramine [norepinephrine reuptake inhibitor]; with idazoxan [norepinephrine alpha-2 receptor antagonist]) or with a two-drug (iloperidone + desipramine; iloperidone + idazoxan) combination for 14 days. Moderate doses of iloperidone (1-5 mg/kg) significantly reduced alcohol drinking (p animal model, iloperidone decreases alcohol drinking as effectively as clozapine, and desipramine appears to amplify this effect. The data suggest that iloperidone, alone or in combination with desipramine, should be tested in patients with schizophrenia and alcohol use disorder. PMID:26796639

    A black coat-color mutant with tremor was discovered in babies of 61 generations of an inbred strain APG of Syrian hamster which had been maintained in the Nippon Institute for Biological Science, Laboratory Animal Research Station. The genetical analysis by matings between four inbred strains which had different genes in the E and B loci and four mutant strains which were introduced the mutant gene into the four inbred strains and characterization were carried out on the mutant. The results obtained are summarized as follows: 1) The mutation occurred in a different locus with E and B loci. 2) The mutant was controlled by an autosomal recessive gene designated as "bt", and it was thought that both tremor and black coat-color were the pleiotropic effect of bt gene. 3) At least one E gene in the E locus was necessary for the appearance of black coat color. Therefore, the coat-color remained cream in ee (cream) hamsters showing only trembling. 4) The degree of blackness of the coat-color of EE hamsters differed from Ee ones. The former was darker than the latter. 5) The mutant may be a useful animal model for studying abnormal myelogenesis and biosynthesis of melanin. PMID:3732409

    Full Text Available Adenovirus infections of immunocompromised pediatric hematopoietic stem cell transplant patients can develop into serious and often deadly multi-organ disease. There are no drugs approved for adenovirus infections. Cidofovir (an analog of 2-deoxycytidine monophosphate is used at times but it can be nephrotoxic and its efficacy has not been proven in clinical trials. Brincidofovir, a promising lipid-linked derivative of cidofovir, is in clinical trials. Ganciclovir, an analog of 2-deoxyguanosine, has been employed occasionally but with unknown efficacy in the clinic. In this study, we evaluated valganciclovir against disseminated adenovirus type 5 (Ad5 infection in our permissive immunosuppressed Syrian hamster model. We administered valganciclovir prophylactically, beginning 12 h pre-infection or therapeutically starting at Day 1, 2, 3, or 4 post-infection. Valganciclovir significantly increased survival, reduced viral replication in the liver, and mitigated the pathology associated with Ad5 infection. In cultured cells, valganciclovir inhibited Ad5 DNA replication and blocked the transition from early to late stage of infection. Valganciclovir directly inhibited Ad5 DNA polymerase in vitro, which may explain, at least in part, its mechanism of action. Ganciclovir and valganciclovir are approved to treat infections by certain herpesviruses. Our results support the use of valganciclovir to treat disseminated adenovirus infections in immunosuppressed patients.

    Some indices of the antioxidant status (content of the alpha-tocopherol, reduced glutathione and ascorbic acid, activity of the glutathione reductase and aryl-esterase) and lipid peroxidation processes in the liver, blood serum, and some blood serum lipoprotein fractions of the Golden Syrian hamsters of different sex and age status under high-caloric diet were investigated. It has been shown that the hypercaloric diet leads to a decreaseng of reduced glutathione content and increase of the level of lipid peroxidation products in the liver of experimental animals. The ascorbic acids content in male liver is decreased and in female liver is increased. In the blood serum under hypercaloric nutrition the accumulation of lipid peroxidation products and alpha-tocopherol content a decrease in ApoB-lipoproteins and HDL is observed. Simultaneously the ascorbic acid content is increased in the blood serum of all experimental animals. Activation of free-radical oxidation both in the liver, and blood serum is more significant in males compared with females. The data obtained allow to suppose that atherosclerotic complications of metabolic syndrome development may be connected to the lipoprotein oxidant status infringement. PMID:18959034

    An analytical GC-TEA method has been developed for the quantitative determination of N-nitrosodiethanolamine (NDELA) in tobacco and tobacco smoke. US smoking and chewing tobaccos and experimental cigarette tobaccos contained between 80 and 420 micrograms/kg of NDELA. Two snuff samples contained 3200 and 6800 micrograms/kg of NDELA. NDELA in mainstream smoke of US cigarettes amounted to 10 - 68 ng per cigarette. Evidence was presented which incriminates diethanolamine as a major precursor for NDELA in tobacco and tobacco smoke. Diethanolamine is used as a solubilizing agent for maleic hydrazide, the major sucker-growth inhibitor for US tobacco crops. NDELA was bioassayed in Syrian golden hamsters by skin painting, swabbing of the oral cavity and by subcutaneous injection. Independently of the form of application, NDELA at the higher dose (500 mg/kg) induced carcinomas of the nasal cavity, papillomas of the trachea and tumours of the larynx in some animals. NDELA uptake through the oral cavity in hamsters is presumably greater than through the skin, judging by the higher tumour yield induced by painting of the oral cavity, compared to skin painting. Studies with 14C-labeled NDELA are currently underway to document this observation quantitiatively. The present analytical data for NDELA in tobacco and tobacco smoke, together with the carcinogenicity data reported here and elsewhere, strongly suggest a review of the use of maleic hydrazide-diethanolamine as sucker-growth inhibitor in the cultivation of tobacco and other crops.

  19. Nasal associated lymphoid tissue of the Syrian golden hamster expresses high levels of PrPC.

    Directory of Open Access Journals (Sweden)

    Melissa D Clouse

    Full Text Available The key event in the pathogenesis of the transmissible spongiform encephalopathies is a template-dependent misfolding event where an infectious isoform of the prion protein (PrPSc comes into contact with native prion protein (PrPC and changes its conformation to PrPSc. In many extraneurally inoculated models of prion disease this PrPC misfolding event occurs in lymphoid tissues prior to neuroinvasion. The primary objective of this study was to compare levels of total PrPC in hamster lymphoid tissues involved in the early pathogenesis of prion disease. Lymphoid tissues were collected from golden Syrian hamsters and Western blot analysis was performed to quantify PrPC levels. PrPC immunohistochemistry (IHC of paraffin embedded tissue sections was performed to identify PrPC distribution in tissues of the lymphoreticular system. Nasal associated lymphoid tissue contained the highest amount of total PrPC followed by Peyer's patches, mesenteric and submandibular lymph nodes, and spleen. The relative levels of PrPC expression in IHC processed tissue correlated strongly with the Western blot data, with high levels of PrPC corresponding with a higher percentage of PrPC positive B cell follicles. High levels of PrPC in lymphoid tissues closely associated with the nasal cavity could contribute to the relative increased efficiency of the nasal route of entry of prions, compared to other routes of infection.

  20. In vivo metabolism of pulmonary alveolar epithelial type II pneumonocytes and macrophages from Syrian hamsters

    International Nuclear Information System (INIS)

    Young adult Syrian hamsters were injected intraperitoneally with 14C-glycerol and 3H-palmitate 17 hr before they were sacrificed and pulmonary alveolar epithelial type II cells and pulmonary alveolar macrophages (PAM) were isolated. Incorporation of the two labeled components into the cellular lipids showed that the 3H-specific activity of the phospholipids from the type II cells was three times that of the PAM and the utilization of 14C-glycerol into phosphatidyl choline (PC) was 50% greater than incorporation into the PC from PAMs. The PC from type II cells showed that 30% was disaturated and from PAMs 21% was disaturated. Another phosphatide, phosphatidyl glycerol contained about one-third of the molecules in disaturated form. These data are consistent with the view that both type II cells and PAMs can synthesize surface-active phospholipids but it is generally accepted that only the pulmonary alveolar epithelial type II cells excrete the disaturated phospholipids which comprise the surface-active components of pulmonary surfactant

    Full Text Available Studies have shown that authoritarian regimes tend to censor the media to limit potential threats to the status quo. While such censorship practices were traditionally aimed at broadcast and print media, the emergence of the Internet and social media in particular, prompted some authoritarian regimes, such as the Assad regime in Syria, to try and exert a similar level of censorship on the Internet as well. During the Arab Spring, the Syrian regime blocked hundreds of websites that provided social networking, news, and other services. Taking Syria as a case study, this paper examines whether Internet censorship succeeded in preventing Internet users from reaching censored online content during 2010−2012. By analyzing the use of Alkasir, a censorship circumvention tool created by the author, the paper provides empirical evidence demonstrating that users were in fact able to bypass censorship and access blocked websites. The findings demonstrate that censorship circumvention tools constituted a threat to the information control systems of authoritarian regimes, highlighting the potential of such tools to promote online freedom of expression in countries where Internet censorship is prevalent.

    Esters are a widespread class of organic compounds found both in industry and the environment. Because esters are often volatile and, therefore, readily inhaled, the capacity of respiratory tract tissues as well as liver S-9 homogenates from rats, rabbits, and Syrian hamsters to hydrolyze a variety of esters was investigated. A new technique to determine hydrolysis rates by measuring carboxylic acid residues using ion chromatography was proven effective. The results indicated that esters, including potentially carcinogenic beta-lactones, are readily hydrolyzed by respiratory tract enzymes. Species and tissue differences were apparent. The nasal ethmoturbinates had especially high levels of esterase activity with tissue weight-normalized activities from rabbits and hamsters for most substrates exceeding all other tissues tested, including liver. Phenyl acetate was the most rapidly hydrolyzed by ethmoturbinate tissue of the esters tested. Among straight chain aliphatic alcohol acetates, hydrolysis rates increased with carbon number up to pentyl alcohol and then decreased. Branched 4-carbon alcohol acetates were less rapidly hydrolyzed than n-butyl acetate. Correlation of hydrophobicity constants with hydrolysis rates indicated that, for the straight chain aliphatic acetates, a bilinear model best fit the data. PMID:3576643

    Full Text Available This paper investigates the long-term and causal relationship between energy intensity, real GDP per capita, urbanization and industrialization in Saudi Arabia over the period 1971–2012 using the breakpoint unit root tests developed by Perron (1989 and the autoregressive distributed lag (ARDL model bounds testing to cointegration proposed by Pesaran et al. (2001 and employing a modified version of the Granger causality test proposed by Toda and Yamamoto (1995. Additionally, to test the robustness of the results, the fully modified ordinary least squares (OLS regression, the dynamic OLS regression, and the Hansen test are used. Our results show that the variables are cointegrated when energy intensity is the dependent variable. It is also found that urbanization positively affects energy intensity in both the short term and the long term. Causality tests indicate that urbanization causes economic output that causes energy intensity in the long term. Our results do not support the urban compaction hypothesis where urban cities benefit from basic public services and economies of scale for public infrastructure. Therefore, measures that slow down the rapid urbanization process should be taken to reduce energy intensity in Saudi Arabia. In addition, reducing energy inefficiency in energy consumption should be a strategy to attain sustainable development in the near future in Saudi Arabia.

  4. Magnetically inferred basement structure in central Saudi Arabia

    1995-05-01

    A compilation of magnetic data acquired during the past three decades for a region in central Saudi Arabia where Precambrian basement is partly exposed on the Arabian shield and partly concealed by overlying Phanerozoic strata, shows a central sector of conspicuous N-S-trending anomalies, a heterogeneous western sector of short-wavelength, high-intensity anomalies, and an eastern sector of low- to moderate-intensity broad-wavelength anomalies. Anomalies in the western and central sectors correlate with Neoproterozoic metavolcanic, metasedimentary, and intrusive rocks of the Arabian shield and are interpreted as delineating extensions of shield-type rocks down-dip beneath Phanerozoic cover. These rocks constitute terranes making up part of a Neoproterozoic orogenic belt that underlies Northeast Africa and western Arabia and it is proposed that their magnetically indicated easternmost extent marks the concealed eastern edge of the orogenic belt in central Arabia. The flat magnetic signature of the eastern sector, not entirely accounted for as an effect of deep burial, may reflect the presence of a crustal block different in character to the terranes of the orogenic belt and, speculatively, may outline a continental block that, according to some tectonic models of the region, collided with the Neoproterozoic terranes and thereby caused their deformation and tectonic accretion.

  5. A refined approach: Saudi Arabia moves beyond crude

    International Nuclear Information System (INIS)

    Saudi Arabia's role in global energy markets is changing. The kingdom is reshaping itself as a supplier of refined petroleum products while moving beyond its long-held role as a simple exporter of crude oil. This change is commensurate with the typical development trajectory of a state progressing to a more advanced stage of global economic integration. Gains from increased refining include reducing fuel imports and capturing margins now bequeathed to competitors. Refining also allows the kingdom to export its heavy crude oil to a wider array of customers, beyond select importers configured to handle heavy crudes. However, the move also presents strategic complications. The world's 'swing supplier' of oil may grow less willing or able to adjust supply to suit market demands. In the process, Saudi Arabia may have to update the old “oil for security” relationship that links it with Washington, augmenting it with a more diverse set of economic and investment ties with individual companies and countries, including China. -- Highlights: •Saudi Arabia is diverting crude oil into an expanding refining sector. •In doing so, the kingdom is moving beyond its role as global “swing supplier” of crude oil. •The kingdom will benefit from increased refining, including enhanced demand for heavy crude. •Strategic complications may force it to seek security partners beyond Washington

    Measurement of indoor radon concentration was performed in Najran region in the south west of Saudi Arabia, using CR-39 dosimeter. Despite many previous studies on indoor radon concentrations in Saudi Arabia, the data available are still limited. The objective of this study, which is the first of its kind in the region, is to have preliminary data of radon in this region. Such measurement will contribute towards further studies in this region of Saudi Arabia. The indoor radon concentration was measured in the villages of Fara Al-Jabal and Badr Al-Janoob (about 2000 m above sea level), Hadadah and Al-Khanig (about 1700 m above sea level). It was found that radon distribution in these villages is normal skewed to the right, with a range of 9±5 to 163±32 Bqm-3 and an average of 49±2 Bqm-3. It was also found that the average radon concentration is independent of altitude. Our findings show that the values are below the safe limit of 150 Bqm-3 set by the Environmental Protection Agency (EPA) of the USA

    In Sudan, prevalence of FGM is declining; likely as a result of changing attitude surrounding FGM, as more women believe the practice should be discontinued amid growing awareness about its health dangers. DFID Sudan opinion poll data collected from 2012 to 2014 was used. Bayesian geo-additive mixed models were used to map the spatial distribution of the likelihood of pro-FGM attitude at the state-level accounting for associated risk factors. During 2012 to 2014, the overall proportion of pro-FGM was 27.5% and 18.3% respectively with striking variations within states. People with pro-FGM attitude were more likely to be un-educated, living in rural settings with strong tribal identity. Individuals from Darfur were more likely to be pro-FGM when compared to the North state. The decrease in the practice of cutting observed between the 2006 and 2010 Sudanese Household Surveys and the resulting shift in attitude make a compelling case for public health policy to eradicate the FGM practice.

    RF-(Arg-Phe) related peptides (RFRP-1 and -3) are considered to play a role in the seasonal regulation of reproduction; however, the effect of the peptides depends on species and gender. This study aimed at comparing the RFRP system in male and female Syrian hamsters over long and short...... in the anteroventral-periventricular nucleus is higher only in females adjusted to a short photoperiod. Our results suggest that the RFRP system, which is strongly regulated by photoperiod in both male and female Syrian hamsters, is particularly important in females, with a distinct role in the anteroventral...... photoperiods to investigate the neuroanatomical basis of these differential effects. The neuroanatomical distribution of RFRP neurons and fibers, revealed using an antiserum recognizing RFRP-1 and -3, as well as GPR147 mRNA, are similar in male and female Syrian hamsters.

The aim of this study was to assess the level of public knowledge and attitude toward blood donation in Saudi Arabia. Methods: Using a previously validated questionnaire that comprises 38 questions to assess the levels of knowledge, attitudes, and motivations towards blood donation, 469 Saudi adults who attended different shopping malls in Riyadh, Saudi Arabia were surveyed. Multiple regression analyses were used to identify the significant predictors of blood donation, with the significance set at P<0.05. Results: Approximately half of all subjects (53.3% reported that they had previously donated blood, 39% of whom had donated more than once. The knowledge percentage mean score was 58.07%, denoting a poor level of knowledge, with only 11.9% reporting a good level of knowledge. The attitude percentage mean score towards donation was 75.45%, reflecting a neutral attitude towards donating blood, with 31.6% reporting a positive attitude. Donation was significantly more prevalent among males than females (66% versus 13.3%; P<0.001. After adjustment for confounders, a higher knowledge score (t=2.59; P=0.01, a higher attitude score (t=3.26; P=0.001, and male sex (t=10.45; P<0.001 were significant predictors of blood donation. An inability to reach the blood donation centers and a fear of anemia were the main reasons for females not donating blood (49.9% and 35.7%, respectively, whereas a lack of time was the main reason for males (59.5%. Conclusion: Prevalence of blood donation was less than satisfactory among the Saudi public, probably due to misconceptions, poor

  11. Veterinaires Sans Frontieres Suisse Activities to Eradicate Rinderpest from Southern Sudan

    International Nuclear Information System (INIS)

    As part of a joint programme with a dozen other NGOs working in southern Sudan under the global umbrella of the United Nations OLS, in 1995, VSF Suisse (VSF-CH) started to collaborate with FAO on the eradication of rinderpest in this part of Africa. VSF-CH has been working in eastern Africa since 1995. Its overall objective in southern Sudan was to improve household food security and quality of life for 71,000 households in Northern Bahr El Ghazal Region and 63,000 in Western Upper Nile Region, by improving livestock productivity. The first specific objective was to improve livestock health and productivity by supporting a viable community-based animal health service. The second was to contribute to the eradication of rinderpest by 2010, following the recommendations of GREP, OIE and PACE. Activities were carried out through ten VSF-CH base stations covering 14 payams in Aweil East and Twic Counties of Northern Bahr el Ghazal, and 18 payams in Leer and Koch Counties of southern Western Upper Nile. The beneficiaries were Nuer and Dinka pastoral communities, who were suffering from the longstanding war that hampered daily life in southern Sudan for 20 years until a peace agreement was signed in January 2005. The main task was to provide technical support for the delivery of animal health services: rinderpest vaccination, until it was replaced by surveillance in January 2002; surveillance for other transboundary animal diseases; drug and vaccine distribution; treatments and vaccinations; and capacity building. The first aim was to control livestock diseases with a significant impact on reducing milk yields, as milk is the major marketable or consumable product from livestock raising. Benefits that households gain from healthy animals include milk; and animals for use as dowries in Dinka marriages, for herd replacement, as exchange for grain in times of hunger, or for sale to raise capital to purchase heifers to increase herd sizes. For the second objective

    Meteorologists are required to provide accurate and comprehensive weather information for planning and operational aviation, agricultural, water projects and also for the public. In general, weather phenomena such as thunderstorms over the area between the tropics and the middle latitudes are not fully understood, particularly in the Middle East area, for many reasons such as: 1) the complexity of the nature of the climate due to the wide-ranging diversity in the topography and landscape in the area; 2) the lack of meteorological data in the area; and 3) the lack of studies on local weather situations. In arid regions such as Saudi Arabia, the spatial and temporal variation of thunderstorms and associated rainfall are essential in determining their effects on social and economic conditions. Thunderstorms form rapidly, due to the fact that the significant heating of the air from the surface and the ensuing rainfall usually occurs within a short period of time. Thus, understanding thunderstorms and rainfall distribution in time and space would be useful for hydrologists, meteorologists and for environmental studies. Research all over the world has shown, however, that consideration of local factors like Low Level Jets (LLJ), moisture flux, sea breezes, and the Red Sea Convergence Zone (RSCZ) would be valuable in thunderstorm prediction. The combined effects of enhanced low-level moisture convergence and layer destabilization due to upslope flow over mountainous terrain has been shown to be responsible for thunderstorm development in otherwise non-favourable conditions. However, there might be other synoptic features associated with heavy thunderstorms or cause them, but these features have not been investigated in any research in Saudi Arabia. Thus, relating the local weather and synoptic situations with those over the middle latitudes will provide a valuable background for the forecasters to issue the medium-range forecasts which are important for many projects

    The daily pattern of blood-borne melatonin varies seasonally under the control of a multi-oscillator circadian pacemaker. Here we examine patterns of melatonin secretion and locomotor activity in Siberian and Syrian hamsters entrained to bimodal LDLD8:4:8:4 and LD20:4 lighting schedules that facilitate novel temporal arrangements of component circadian oscillators. Under LDLD, both species robustly bifurcated wheel-running activity in distinct day scotophase (DS) and night scotophase (NS) bouts. Siberian hamsters displayed significant melatonin increases during each scotophase in LDLD, and in the single daily scotophase of LD20:4. The bimodal melatonin secretion pattern persisted in acutely extended 16 h scotophases. Syrian hamsters, in contrast, showed no significant increases in plasma melatonin during either scotophase of LDLD8:4:8:4 or in LD20:4. In this species, detectable levels were observed only when the DS of LDLD was acutely extended to yield 16 h of darkness. Established species differences in the phase lag of nocturnal melatonin secretion relative to activity onset may underlie the above contrast: In non-bifurcated entrainment to 24 h LD cycles, Siberian hamsters show increased melatonin secretion within ≈ 2 h after activity onset, whereas in Syrian hamsters, detectable melatonin secretion phase lags activity onset and the L/D transition by at least 4 h. The present results provide new evidence indicating multi-oscillator regulation of the waveform of melatonin secretion, specifically, the circadian control of the onset, offset and duration of nocturnal secretion.

    Full Text Available BackgroundIn recent years, several plant species have been used as bioindicators to evaluate the toxicity of environmental contaminants on vegetal organisms. In this study, Egyptian clover and Sudan grass seedlings were grown in four cadmium (Cd concentration levels (0.0, 25, 50 and 100 µM in MS media to analyze growth responses, Cd accumulation in the shoots and roots of plantlets, proline contents, chlorophylls content and MDA levels of both plantlets. As well as RAPD analysis and leaves ultrastructure were detected.ResultsThe results showed that there was a significant decrease in root and shoot lengths, Chl a, Chl b, total Chl and carotenoids contents for both Egyptian clover and Sudan grass. However, there was a significant increase in Cd accumulation, proline and malondialdehyde (MDA levels. The genetic variation between Egyptian clover and Sudan grass were evaluated using random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR markers to establish specific DNA markers associated with Cd stress. The results of transimssion electron microscopy (TEM showed a clear disorder in the Cd treated Egyptian clover and Sudan grass seedlings.ConclusionIn conclusion, biochemical, molecular and ultrastructure changes in Egyptian clover and Sudan grass could be used as a useful biomarker assay for the detection of genotoxic effects of Cd stress on plants. However, it is necessary to be further confirmed and optimized in the future research.

    Full Text Available Abstract Background Crimean-Congo hemorrhagic fever (CCHF, a tick-borne disease caused by Crimean-Congo hemorrhagic fever virus (CCHFV, is a member of the genus Nairovirus in the family Bunyaviridae. Recently, CCHFV has been reported as an important emerging infectious viral pathogen in Sudan. Sporadic cases and multiple CCHF outbreaks, associated with nosocomial chain of transmission, have been reported in the Kordufan region of Sudan. Aims To confirm CCHF in an index patient and attending physician in North Kordufan region, Sudan, and to provide some information on virus genetic lineages. Methods Antibody captured ELISA, reverse transcription PCR, partial S segment sequences of the virus and subsequent phylogenetic analysis were used to confirm the CCHFV infection and to determine the virus genetic lineages. Results CCHF was confirmed by monitoring specific IgM antibody and by detection of the viral genome using RT-PCR. Treatment with oral ribavirin, replacement with fluid therapy, blood transfusion and administration of platelets concentrate resulted in rapid improvement of the health condition of the female physician. Phylogenetic analysis of the partial S segment sequences of the 2 CCHFV indicates that both strains are identical and belong to Group III virus lineage, which includes viruses from Africa including, Sudan, Mauritania, South Africa and Nigeria. Conclusion Further epidemiologic studies including, CCHFV complete genome analysis and implementation of improved surveillance are urgently needed to better predict and respond to CCHF outbreaks in the Kordufan region, Sudan.

    A simple and sensitive electrochemical method was developed to determine the concentration of Sudan I in chili powder based on silver nanoparticles decorated graphene oxide modified glassy carbon electrode (AgNPs@GO/GCE). The voltammetry behaviour of Sudan I on modified GCE was investigated in phosphate buffer medium (PBS) with various pH ranges and the electron transfer properties were studied. It is found that the AgNPs@GO/GCE can catalyse the reduction of azo group, -N=N- followed by electrochemical oxidation of (-)OH group present in Sudan I dye molecule. Quantitative detection of Sudan I present in food products was carried out by amperometry method in which reduction potential was fixed at -0.77 V vs. Ag/AgCl. The amperometry method showed an excellent performance with a sensitivity of 6.83 μA mM(-1) and a detection limit of 11.4 × 10(-7)ML(-1). A linear calibration graph was constructed in the ranging 3.90 × 10(-6) to 3.19 × 10(-5)ML(-1). The method was successfully applied for the determination of Sudan I in red chili powder samples.

    2010-01-01

    Full Text Available This study proposes a revised technology acceptance model that integrates expectation confirmation theory to measure gender differences with regard to continuance online shopping intentions in Saudi Arabia. The sample consists of 650 female respondents. A structural equation model confirms model fit. Perceived enjoyment, usefulness, and subjective norms are determinants of online shopping continuance in Saudi Arabia. High and low online spenders among women in Saudi Arabia are equivalent. The structural weights are also largely equivalent, but the regression paths from perceived site quality to perceived usefulness is not invariant between high and low e-shoppers in Saudi Arabia. This research moves beyond online shopping intentions and includes factors affecting online shopping continuance. The research model explains 60% of the female respondents’ intention to continue shopping online. Online strategies cannot ignore either the direct and indirect spending differences on continuance intentions, and the model can be generalized across Saudi Arabia.

  19. The Role and Responsibility of the National Regulator of Radiation Sources and Materials in Saudi Arabia

    International Nuclear Information System (INIS)

    There are neither nuclear power reactors nor are there research reactors in Saudi Arabia. However, the country imports a lot of radioactive sources that are used in different fields such as medicine, hydrology, industry and research. Usage of radioactive material is governed by national and the IAEA regulations for the safe usage and transport of radioactive materials. KACST (King Abdulaziz City for Science and Technology) is an independent scientific organization established in 1977. It is the national competent authority that sets the rules of transporting, using and disposing of radioactive sources in Saudi Arabia.. This paper discusses the role of KACST and other authorities in the country regarding the 1) licensing and evaluation of the importing and exporting applications of radioactive sources and/or devices in Saudi Arabia, 2) The regulatory framework of radiation protection in Saudi Arabia, 3) the management of radioactive wastes in Saudi Arabia.

    In the context of ongoing armed conflicts in Libya, Syria, Yemen, and Iraq, it is vital to foster nuanced understandings of the relationship between health, violence, and everyday life in the Middle East and North Africa. In this article, we explore how healthcare access interacts with humanitarian bureaucracy and refugees' daily experiences of exile. What are the stakes involved with accessing clinical services in humanitarian situations? How do local conditions structure access to healthcare? Building on the concept of "therapeutic geographies," we argue for the integration of local socio-political context and situated knowledge into understandings of humanitarian healthcare systems. Using evidence gathered from participant observation among Syrian and Palestinian refugees in Lebanon, we demonstrate how procedures developed to facilitate care-such as refugee registration and insurance contracting-can interact with other factors to simultaneously prevent and/or disincentivize refugees' accessing healthcare services and expose them to structural violence. Drawing on two interconnected ethnographic encounters in a Palestinian refugee camp and in a Lebanese public hospital, we demonstrate how interactions surrounding the clinical encounter reveal the social, political, and logistical complexities of healthcare access. Moreover, rather than hospital visits representing discrete encounters with the Lebanese state, we contend that they reveal important moments in an ongoing process of negotiation and navigation within and through the constraints and uncertainties that shape refugee life. As a result, we advocate for the incorporation of situated forms of knowledge into humanitarian healthcare practices and the development of an understanding of healthcare access as nested in the larger experience of everyday refugee life.

    Essential oil components from turmeric (Curcuma longa L.) are documented for neuroprotective, anti-cancer, anti-thrombotic and antioxidant effects. The present study aimed to investigate the disease-modifying potential of curcuma oil (C. oil), a lipophilic component from C. longa L., in hyperlipidaemic hamsters. Male golden Syrian hamsters were fed a chow or high-cholesterol (HC) and fat-rich diet with or without C. oil (30, 100 and 300 mg/kg) for 28 d. In HC diet-fed hamsters, C. oil significantly reduced plasma total cholesterol, LDL-cholesterol and TAG, and increased HDL-cholesterol when compared with the HC group. Similar group comparisons showed that C. oil treatment reduced hepatic cholesterol and oxidative stress, and improved liver function. Hyperlipidaemia-induced platelet activation, vascular dysfunction and repressed eNOS mRNA expression were restored by the C. oil treatment. Furthermore, aortic cholesterol accumulation and CD68 expression were also reduced in the C. oil-treated group. The effect of C. oil at 300 mg/kg was comparable with the standard drug ezetimibe. Delving into the probable anti-hyperlipidaemic mechanism at the transcript level, the C. oil-treated groups fed the chow and HC diets were compared with the chow diet-fed group. The C. oil treatment significantly increased the hepatic expression of PPARa, LXRa, CYP7A1, ABCA1, ABCG5, ABCG8 and LPL accompanied by reduced SREBP-2 and HMGCR expression. C. oil also enhanced ABCA1, ABCG5 and ABCG8 expression and suppressed NPC1L1 expression in the jejunum. In the present study, C. oil demonstrated an anti-hyperlipidaemic effect and reduced lipid-induced oxidative stress, platelet activation and vascular dysfunction. The anti-hyperlipidaemic effect exhibited by C. oil seems to be mediated by the modulation of PPARa, LXRa and associated genes involved in lipid metabolism and transport.

  2. Modulation of Vascular ACE by Oxidative Stress in Young Syrian Cardiomyopathic Hamsters: Therapeutic Implications

    Full Text Available Increased vascular angiotensin-converting enzyme (ACE activity and oxidative stress are present in young Syrian cardiomyopathic hamsters (SCH before the clinical manifestation of heart failure (HF. The developmental time-course of these alterations and their potential interactions, however, are still unknown. We evaluated mRNA and protein levels of ACE, endothelial nitric oxide synthase (eNOS, and inducible nitric oxide synthase (iNOS in the vasculature of SCH from one to four months of age. Total RNA and proteins were quantified with real-time reverse transcriptase-polymerase chain reaction (RT-PCR and Western blot, respectively. The role of nitric oxide (NO on vascular ACE activity was also assessed. ACE mRNA and protein levels were up-regulated in SCH at two months of age compared with controls (CT (p < 0.05. At this two-month stage, eNOS protein levels were lower in SCH (87% than in CT (100% (p < 0.05, although iNOS protein levels increased significantly (482% compared to CT (100%; p < 0.05. In addition, ACE mRNA expression and activity were modulated by NO at two months of age. Thus, the combination of low eNOS and high iNOS protein levels may underlie vascular renin-angiotensin system (RAS over-activation. Altogether, these factors may contribute to the development of endothelial dysfunction and vascular hyper-reactivity in the early stages of heart failure, and eventually trigger cardiac deterioration in this animal model of HF.

    Full Text Available Abstract Kidney tumors from stilbene estrogen (diethylstilbestrol-treated Syrian hamsters were screened for somatic genetic alterations by Random Amplified Polymorphic DNA-polymerase chain-reaction (RAPD-PCR fingerprinting. Fingerprints from tumor tissue were generated by single arbitrary primers and compared with fingerprints for normal tissue from the same animal, as well as normal and tumor tissues from different animals. Sixty one of the arbitrary primers amplified 365 loci that contain approximately 476 kbp of the hamster genome. Among these amplified DNA fragments, 44 loci exhibited either qualitative or quantitative differences between the tumor tissues and normal kidney tissues. RAPD-PCR loci showing decreased and increased intensities in tumor tissue DNA relative to control DNA indicate that loci have undergone allelic losses and gains, respectively, in the stilbene estrogen-induced tumor cell genome. The presence or absence of the amplified DNA fragments indicate homozygous insertions or deletions in the kidney tumor DNA compared to the age-matched normal kidney tissue DNA. Seven of 44 mutated loci also were present in the kidney tissues adjacent to tumors (free of macroscopic tumors. The presence of mutated loci in uninvolved (non-tumor surrounding tissue adjacent to tumors from stilbene estrogen-treated hamsters suggests that these mutations occurred in the early stages of carcinogenesis. The cloning and sequencing of RAPD amplified loci revealed that one mutated locus had significant sequence similarity with the hamster Cyp1A1 gene. The results show the ability of RAPD-PCR to detect and isolate, in a single step, DNA sequences representing genetic alterations in stilbene estrogen-induced cancer cells, including losses of heterozygosity, and homozygous deletion and insertion mutations. RAPD-PCR provides an alternative molecular approach for studying cancer cytogenetics in stilbene estrogen-induced tumors in humans and experimental

    Full Text Available Context Our previous studies showed that porcine pancreatic enzymes in Syrian golden hamsters with peripheral insulin resistance normalizes the plasma insulin level, reduces the size of enlarged islets and inhibits the increased DNA synthesis in the beta-cell of islets. Objective In order to exclude the possibility that these effects was attributed to some contaminants of this crude material, we tested the effect of purified fungal pancreatic enzyme (FPE that contains primarily amylase and lipase without (FPE and with addition of chymotrypsin (FPE+chy. Material and methods In a pilot study we tested the effect of different doses of FPE given in drinking water on insulin level, islet size and DNA synthesis of islet cells in hamsters with induced peripheral insulin resistance by a high fat diet. The most effective dose of FPE on these parameters was used in a long-term experiment with FPE and FPE+chy in hamsters fed a high-fat diet for 36 or 40 weeks. Results In the pilot study a dose of 2 g/kg body weight was found to be optimal for controlling the body weight, normalizing plasma insulin level, the size of islets, the DNA synthesis and the number of insulin cells in the islets. These data were produced in the long-term study, where steatorrhea was also inhibited. Addition of chymotrypsin had no effects on these parameters. Conclusion Pancreatic lipase and amylase appear to be responsible for the observed effects and offer a safe and effective natural product for the treatment of pancreatic diseases, including acute pancreatitis, chronic pancreatic, cystic fibrosis and any conditions associated with peripheral insulin resistance, including obesity and type 2 diabetes. The possible mechanism of the action is discussed.

    Although exposure to social stress leads to increased depression-like and anxiety-like behavior, some individuals are more vulnerable than others to these stress-induced changes in behavior. Prior social experience is one factor that can modulate how individuals respond to stressful events. In this study, we investigated whether experience-dependent resistance to the behavioral consequences of social defeat was associated with a specific pattern of neural activation. We paired weight-matched male Syrian hamsters in daily aggressive encounters for 2 weeks, during which they formed a stable dominance relationship. We also included control animals that were exposed to an empty cage each day for 2 weeks. Twenty-four hours after the final pairing or empty cage exposure, half of the subjects were socially defeated in 3, 5-min encounters, whereas the others were not socially defeated. Twenty-four hours after social defeat, animals were tested for conditioned defeat in a 5-min social interaction test with a non-aggressive intruder. We collected brains after social defeat and processed the tissue for c-Fos immunoreactivity. We found that dominants were more likely than subordinates to counter-attack the resident aggressor during social defeat, and they showed less submissive and defensive behavior at conditioned defeat testing compared with subordinates. Also, social status was associated with distinct patterns of defeat-induced neural activation in select brain regions, including the amygdala, prefrontal cortex, hypothalamus, and lateral septum. Our results indicate that social status is an important form of prior experience that predicts both initial coping style and the degree of resistance to social defeat. Further, the differences in defeat-induced neural activation suggest possible brain regions that may control resistance to conditioned defeat in dominant individuals.

    Resilience is an active process that involves a discrete set of neural substrates and cellular mechanisms and enables individuals to avoid some of the negative consequences of extreme stress. We have previously shown that dominant individuals show less stress-induced changes in behavior compared to subordinates using a conditioned defeat model in male Syrian hamsters (Mesocricetus auratus). To rule out pre-existing differences between dominants and subordinates, we examined whether 14 days of dominance experience is required to reduce the conditioned defeat response and whether the development of conditioned defeat resistance correlates with defeat-induced neural activation in select brain regions. We paired hamsters in daily 5-min aggressive encounters for 1, 7, or 14 days and then exposed animals to 3, 5-min social defeat episodes. The next day animals received conditioned defeat testing which involved a 5-min social interaction test with a non-aggressive intruder. In separate animals brains were collected after social defeat for c-Fos immunohistochemistry. We found that 14-day dominants showed a decreased conditioned defeat response compared to 14-day subordinates and controls, while 1-day and 7-day dominants did not differ from their subordinate counterparts. Also, the duration of dominance relationship was associated with distinct patterns of defeat-induced neural activation such that only 14-day dominants showed elevated c-Fos immunoreactivity in the ventral medial prefrontal cortex, medial amygdala, and lateral portions of the ventral medial hypothalamus. Our data suggest that resistance to social stress develops during the maintenance of dominance relationships and is associated with experience-dependent neural plasticity in select brain regions.

    Conditioned defeat (CD) is a behavioral response that occurs in Syrian hamsters after they experience social defeat. Subsequently, defeated hamsters no longer produce territorial aggression but instead exhibit heightened levels of avoidance and submission, even when confronted with a smaller, non-aggressive intruder. Dopamine in the nucleus accumbens is hypothesized to act as a signal of salience for both rewarding and aversive stimuli to promote memory formation and appropriate behavioral responses to significant events. The purpose of the present study was to test the hypothesis that dopamine in the nucleus accumbens modulates the acquisition and expression of behavioral responses to social defeat. In Experiment 1, bilateral infusion of the non-specific D1/D2 receptor antagonist cis(z)flupenthixol (3.75 μg/150 nl saline) into the nucleus accumbens 5 min prior to defeat training significantly reduced submissive and defensive behavior expressed 24h later in response to a non-aggressive intruder. In Experiment 2, infusion of 3.75 μg cis-(Z)-flupenthixol 5 min before conditioned defeat testing with a non-aggressive intruder significantly increased aggressive behavior in drug-infused subjects. In Experiment 3, we found that the effect of cis-(Z)-flupenthixol on aggression was specific to defeated animals as infusion of drug into the nucleus accumbens of non-defeated animals did not significantly alter their behavior in response to a non-aggressive intruder. These data demonstrate that dopamine in the nucleus accumbens modulates both acquisition and expression of social stress-induced behavioral changes and suggest that the nucleus accumbens plays an important role in the suppression of aggression that is observed after social defeat.

  9. Peeling skin syndrome: 11 cases from Saudi Arabia

    International Nuclear Information System (INIS)

    Peeling skin syndrome (PSS) is a rare genodermatoses of probable autosomal recessive inheritance in Saudi Arabia, consanguinity of parents is common and consequently the occurrence of family disease, including that of the skin, is not uncommon. To characterize the clinical and pathological features of PSS in Saudi Arabia, we reviewed the medical records and clinical photographs of patients with recurring blistering diseases and conducted a histopathologic evaluation of skin biopsies to identify the site of cleavage. Eleven persons with PSS were seen at King Khalid National Guard Hospital in Jeddah between the years 1986 and 2005. Ages ranged between 2 and 15 years and there were 9 males (81.8%) and 2 females (18.2%). The most common presentation in the majority of patients was localized spontaneous peeling of the skin. Eight patients (72.8%) had a history of vesicles that were small, dry and peeled away. Trauma did no play role in blister formation. All patients were local from Bedouin tribes where a family history of a similar complaint was documented in 8 cases (72.7%). And consanguinity of marriage was evident on 6 patients (54.5%). Histological examination of the biopsies showed either intracorneal or superficial subcorneal cleavage above the granuler layer in all biopsied patients. Although rare, PSS occurs in Saudi Arabia and is most likely related to consanguinity of marriages. This disease is generally mild and is characterized by intrascorneal cleavage within the superficial epidermis. The disease should be recognized and not confused with other vasicobullous disease.

    Congenital anomalies contribute a significant proportion of infant morbidity and mortality, as well as fetal mortality. They are generally grouped into three major categories: structural/metabolic, congenital infections, and other conditions. The most prevalent conditions include congenital heart defects, orofacial clefts, Down syndrome, and neural tube defects. Several prenatal diagnostic procedures have been introduced, both cytogenetic (such as chorion biopsy, amniocentesis and funiculocentesis) and biophysical (ultrasound 2-D, 3-D and 4-D, ultrasonography with Doppler, etc.). Insufficient data are currently available from Saudi Arabia on the epidemiology of the lethal congenital abnormalities which should be a priority due to high rate of consanguineous marriages among first cousins and their association with congenital anomalies. In terms of consanguinity and birth defects, a significant positive association has been consistently demonstrated between consanguinity and morbidity, and congenital defects with a complex etiology appear to be both more prevalent in consanguineous families and have a greater likelihood of recurrence. A debate regarding aborting a malformed fetus still exists among the senior Islamic scholars in many of the Islamic countries. The progressive interpretations of Islam have resulted in laws allowing for early abortion on request in two countries; six others permit abortion on health grounds and three more also allow abortion in cases of rape or fetal impairment. In Saudi Arabia, efforts to legalize abortion in certain circumstances have been recently discussed among Senior Religious Scholars and specialized physicians to permit abortions in certain circumstances. In this mini-review we discuss the current debate regarding aborting a malformed fetus in Saudi Arabia with a focus on the Islamic perspective. PMID:24027674

    Full Text Available Little is known about the geographic distribution of common cancers in Saudi Arabia. We explored the spatial incidence patterns of common cancers in Saudi Arabia using spatial autocorrelation analyses, employing the global Moran’s I and Anselin’s local Moran’s I statistics to detect nonrandom incidence patterns. Global ordinary least squares (OLS regression and local geographically-weighted regression (GWR were applied to examine the spatial correlation of cancer incidences at the city level. Population-based records of cancers diagnosed between 1998 and 2004 were used. Male lung cancer and female breast cancer exhibited positive statistically significant global Moran’s I index values, indicating a tendency toward clustering. The Anselin’s local Moran’s I analyses revealed small significant clusters of lung cancer, prostate cancer and Hodgkin’s disease among males in the Eastern region and significant clusters of thyroid cancers in females in the Eastern and Riyadh regions. Additionally, both regression methods found significant associations among various cancers. For example, OLS and GWR revealed significant spatial associations among NHL, leukemia and Hodgkin’s disease (r² = 0.49–0.67 using OLS and r² = 0.52–0.68 using GWR and between breast and prostate cancer (r² = 0.53 OLS and 0.57 GWR in Saudi Arabian cities. These findings may help to generate etiologic hypotheses of cancer causation and identify spatial anomalies in cancer incidence in Saudi Arabia. Our findings should stimulate further research on the possible causes underlying these clusters and associations.

    Sudan I, II, III and IV dyes are banned for use as food colorants in the United States and European Union because they are toxic and carcinogenic. These dyes have been illegally used as food additives in products such as chilli spices and palm oil to enhance their red colour. From 2003 to 2005, the European Union made a series of decisions requiring chilli spices and palm oil imported to the European Union to contain analytical reports declaring them free of Sudan I-IV. In order for the USFDA to investigate the adulteration of palm oil and chilli spices with unapproved colour additives in the United States, a method was developed for the extraction and analysis of Sudan dyes in palm oil, and previous methods were validated for Sudan dyes in chilli spices. Both LC-DAD and LC-MS/MS methods were examined for their limitations and effectiveness in identifying adulterated samples. Method validation was performed for both chilli spices and palm oil by spiking samples known to be free of Sudan dyes at concentrations close to the limit of detection. Reproducibility, matrix effects, and selectivity of the method were also investigated. Additionally, for the first time a survey of palm oil and chilli spices was performed in the United States, specifically in the Washington, DC, area. Illegal dyes, primarily Sudan IV, were detected in palm oil at concentrations from 150 to 24 000 ng ml(-1). Low concentrations (spices and are most likely a result of cross-contamination during preparation and storage and not intentional adulteration.

    The kingdom of Saudi Arabia is currently witnessing a massive support for its healthcare services. This year's fiscal budget for health care is by far the largest in the history of the kingdom. While pursuing the conventional goals of healthcare delivery systems, such as equity, affordability and availability of services, the ministry of education (MOE), formerly called ministry of higher education (MOHE), is also seeking to achieve certain excellence standards, which are expected to set the bar for other countries in the region to follow suit. Almost all, under construction, university hospitals were adopting a paradigm shift in the standard of health care and training provided. This report summarizes these standards.

However, current national estimates on fruit and vegetable consumption in the Kingdom of Saudi Arabia (KSA are nonexistent. We conducted a large household survey to inform the Saudi Ministry of Health (MOH on a major modifiable risk factor: daily consumption of fruits and vegetables. Methods: The Saudi Health Interview Survey is a national multistage survey of individuals aged 15 years or older. It includes questions on sociodemographic characteristics, tobacco consumption, diet, physical activity, health care utilization, different health-related behaviors, and self-reported chronic conditions. We used a backward elimination multivariate logistic regression model to measure association between the Centers for Disease Control and Prevention (CDC-recommended daily consumption of fruits and vegetables and different factors. Results: Between April and June 2013, a total of 10,735 participants completed the survey. Overall, 2.6% of Saudis aged 15 years or older met the CDC guidelines for daily consumption of fruits and vegetables.

    2012-05-01

    Full Text Available This papers aims at investigating the relationship between traditional and social media during the first six months of the Syrian uprising. Thanks to direct testimony made available to the author by various cyber activists inside and outside Syria and through constant monitoring of the official propaganda and the coverage of the Syrian events by the two main pan-Arab satellite TVs, this article intends to investigate how both the regime and the activists attempt to represent the “real events on the ground”. In a country where the foreign and pan-Arab press have been mostly expelled since the beginning of the protests and the consequent repression, these two opposite poles heavily fight on the media level. On the one hand, the propaganda dominates traditional media and has sought to show familiarity with new methods, while maintaining the same content and rhetorical tone. On the other hand, the activists, masters of the new media, attempted to overcome the limitations of their tools, aiming at more traditional forms of communication. In both cases, the Internet has emerged as the main weapon of this media confrontation.

    2-Arachidonoyl glycerol (2-AG) is a major endocannabinoid and an important regulator of neuroendocrine system. In Syrian hamster and human, we found that 2-AG is synthesized in the hypophysial pars tuberalis (PT), an interface between photoperiodic melatonin signals and neuroendocrine output pathways. The target of 2-AG produced in the PT is likely to be the pars distalis (PD). Here we demonstrate that 2-AG in combination with forskolin stimulated prolactin secretion from PD organ cultures of Syrian hamsters, whereas incubation with 2-AG alone had no effect. Forskolin-induced prolactin secretion was also significantly enhanced when cultured PD tissue was preincubated with 2-AG. The stimulatory effects of 2-AG on prolactin secretion were blocked by AM251, a selective CB1 antagonist, and were still observed in the presence of quinpirole, a D2-class dopamine receptor agonist. 2-AG also enhanced prolactin secretion in the presence of adenosine, while it had little effect when applied together with adenosine diphosphate (ADP) and adenosine triphosphate (ATP). Moreover, the effect of forskolin was mimicked by adenosine in a dose-dependent manner. In conclusion, our data suggest that 2-AG sensitizes the PD tissue to potentiate the stimulating effects of forskolin and adenosine on prolactin secretion and thus provide novel insight into the mode of action of 2-AG in the PD.

    Full Text Available Andes virus (ANDV is highly pathogenic in humans and is the primary etiologic agent of hantavirus cardiopulmonary syndrome (HCPS in South America. Case-fatality rates are as high as 50% and there are no approved vaccines or specific therapies for infection. Our laboratory has recently developed a replication-competent recombinant vesicular stomatitis virus (VSV-based vaccine that expressed the glycoproteins of Andes virus in place of the native VSV glycoprotein (G. This vaccine is highly efficacious in the Syrian hamster model of HCPS when given 28 days before challenge with ANDV, or when given around the time of challenge (peri-exposure, and even protects when administered post-exposure. Herein, we sought to test the durability of the immune response to a single dose of this vaccine in Syrian hamsters. This vaccine was efficacious in hamsters challenged intranasally with ANDV 6 months after vaccination (p = 0.025, but animals were not significantly protected following 1 year of vaccination (p = 0.090. The decrease in protection correlated with a reduction of measurable neutralizing antibody responses, and suggests that a more robust vaccination schedule might be required to provide long-term immunity.

    The Syrian refugee crisis in Lebanon required a fast and efficient comprehensive rescue strategy. Professionals working in emergency response were neither prepared to provide psychological first aid nor prepared to screen for mental health disorders in child refugees. This article examines the efficacy of a national training program in psychological first aid (PFA) to enhance the readiness of mental health field workers in the Syrian refugee response. Participant (N = 109) were recruited from Lebanese ministries and nongovernmental organizations. They received a 2.5-day training on PFA and on screening for mental health disorders in children. Their knowledge and perceived readiness were assessed before the training, immediately after the training, and 1 month after the training using 2 evaluation forms. Evaluation Form A was a multiple choice questionnaire composed of 20 questions and created on the basis of the content of the training, and Evaluation Form B was a Likert-type scale of 20 items created based on the core components of PFA. The data of 60 participants were analyzed. The results showed a significant increase in knowledge and readiness, specifically on the components related to the principles and techniques of PFA.

    Dose-response studies were conducted with Syrian hamsters exposed to polyethylene glycol p-isooctylphenyl ether (Triton X-100) via inhalation or bronchopulmonary lavage. Syrian hamsters were exposed to an aerosol of Triton X-100 with a mass median aerodynamic diameter of 1.5 ..mu..m and a concentration of 3.0 mg/liter. Estimated initial lung burdens of Triton X-100 ranged from 800 to 3100 ..mu..g. Hamsters were lavaged with concentrations of Triton X-100 ranging from 0.01 to 0.10% in isotonic saline resulting in initial lung burdens of Triton X-100 that ranged from 300 to 3200 ..mu..g. The LD50/7 values were 1700 ..mu..g (1300 to 2100 ..mu..g, 95% confidence limits) for the inhalation study and 2100 (1900 to 2700) ..mu..g for the lavage study. The difference between the LD50/7 values for the two methods of exposure was not significant. However, histopathological examination revealed differences in the nature and distribution of pathologic changes observed in animals exposed by the two routes of administration. Animals exposed by inhalation died as a result of ulcerative laryngitis and laryngeal edema with only minimal pulmonary pathologic alterations. Animals exposed by lavage, where the larynx was not exposed to Triton X-100, died from pulmonary edema and acute exudative pneumonia. These results demonstrate the need for careful selection of exposure methods to meet the specific objectives of a toxicology study.

    Hair length in mammals is generally regulated by the hair cycle, and its disruption leads to abnormal hair morphogenesis in several species. FGF5, one of the hair cycle regulators, has a role in inducing catagen, and that mutation causes abnormal hair length in both sexes in humans, mice, dogs, and cats. Male-dominant long-haired coat (MALC) is an inbred strain of Syrian hamster exhibiting spontaneous long hair in males. After castration, MALC exhibited significantly shorter hair than the control individuals, but testosterone administration to castrated MALC showed reversion to the original phenotype. Moreover, flutamide administration led to MALC phenotype repression. Histological analysis revealed that hair follicle regression was shown in the wild-type 4 weeks after depilation, but that of MALC remained in the anagen phase. We detected a c.546delG of Fgf5 in MALC (Fgf5malc) that might lead to truncation resulting from a frame shift in FGF5 (p.Arg184GlyfsX6). Additionally, homozygous Fgf5malc was only detected in long-haired (Slc:Syrian×MALC)F2 and (J-2-Nn×MALC)F2 progenies, and all homozygous wild and heterozygous Fgf5malc individuals showed normal hair length. Thus, Fgf5malc leads to male-dominant long hair via a prolonged anagen phase which is affected by testosterone in hamsters. To our knowledge, this report is the first to present the sexual dimorphism of hair length caused by the Fgf5 mutation.

  5. Deforestation and greenhouse gas emissions associated with fuelwood consumption of the brick making industry in Sudan

    International Nuclear Information System (INIS)

    The study focuses on the role of the fired clay brick making industry (BMI) on deforestation and greenhouse gas (GHG) emissions in Sudan. The BMI is based on numerous kilns that use biomass fuel, mainly wood which is largely harvested unsustainably. This results in potential deforestation and land degradation. Fuelwood consumption data was collected using interviews and questionnaires from 25 BMI enterprises in three administrative regions, namely Khartoum, Kassala and Gezira. Annual fuelwood consumption data (t dm yr-1) was converted into harvested biomass (m3) using a wood density value of 0.65 t dm m-3. For annual GHG estimations, the methodological approach outlined by the Intergovernmental Panel on Climate Change (IPCC) was used. According to our results, the annual deforestation associated with the BMI for the whole of Sudan is 508.4 x 103 m3 of wood biomass, including 267.6 x 103 m3 round wood and 240.8 x 103 m3 branches and small trees. Total GHG emissions from the Sudanese BMI are estimated at 378 028 t CO2, 15 554 t CO, 1778 t CH4, 442 t NOX, 288 t NO and 12 t N2O per annum. The combined CO2-equivalent (global warming potential for 100-year time horizon) of the GHG emissions (excluding NOX and NO) is 455 666 t yr-1. While these emissions form only a small part of Sudan's total GHG emissions, the associated deforestation and land degradation is of concern and effort should be made for greater use of sustainable forest resources and management

    Full Text Available Abstract Background Phlebotomus papatasi the vector of cutaneous leishmaniasis (CL is the most widely spread sand fly in Sudan. No data has previously been collected on insecticide susceptibility and/or resistance of this vector, and a first study to establish a baseline data is reported here. Methods Sand flies were collected from Surogia village, (Khartoum State, Rahad Game Reserve (eastern Sudan and White Nile area (Central Sudan using light traps. Sand flies were reared in the Tropical Medicine Research Institute laboratory. The insecticide susceptibility status of first progeny (F1 of P. papatasi of each population was tested using WHO insecticide kits. Also, P. papatasi specimens from Surogia village and Rahad Game Reserve were assayed for activities of enzyme systems involved in insecticide resistance (acetylcholinesterase (AChE, non-specific carboxylesterases (EST, glutathione-S-transferases (GSTs and cytochrome p450 monooxygenases (Cyt p450. Results Populations of P. papatasi from White Nile and Rahad Game Reserve were sensitive to dichlorodiphenyltrichloroethane (DDT, permethrin, malathion, and propoxur. However, the P. papatasi population from Surogia village was sensitive to DDT and permethrin but highly resistant to malathion and propoxur. Furthermore, P. papatasi of Surogia village had significantly higher insecticide detoxification enzyme activity than of those of Rahad Game Reserve. The sand fly population in Surogia displayed high AChE activity and only three specimens had elevated levels for EST and GST. Conclusions The study provided evidence for malathion and propoxur resistance in the sand fly population of Surogia village, which probably resulted from anti-malarial control activities carried out in the area during the past 50 years.

    The summer rainfall across Sahelian-Sudan is one of the main sources of water for agriculture, human, and animal needs. However, the rainfall is characterized by large interannual variability, which has attracted extensive scientific efforts to understand it. This study attempts to identify the source regions that contribute to the Sahelian-Sudan moisture budget during July through September. We have used an atmospheric general circulation model with an embedded moisture-tracing module (Community Atmosphere Model version 3), forced by observed (1979-2013) sea-surface temperatures. The result suggests that about 40% of the moisture comes with the moisture flow associated with the seasonal migration of the Intertropical Convergence Zone (ITCZ) and originates from Guinea Coast, central Africa, and the Western Sahel. The Mediterranean Sea, Arabian Peninsula, and South Indian Ocean regions account for 10.2%, 8.1%, and 6.4%, respectively. Local evaporation and the rest of the globe supply the region with 20.3% and 13.2%, respectively. We also compared the result from this study to a previous analysis that used the Lagrangian model FLEXPART forced by ERA-Interim. The two approaches differ when comparing individual regions, but are in better agreement when neighboring regions of similar atmospheric flow features are grouped together. Interannual variability with the rainfall over the region is highly correlated with contributions from regions that are associated with the ITCZ movement, which is in turn linked to the Atlantic Multidecadal Oscillation. Our result is expected to provide insights for the effort on seasonal forecasting of the rainy season over Sahelian Sudan.

  8. Binding of Sudan II and IV to lecithin liposomes and E. coli membranes: insights into the toxicity of hydrophobic azo dyes

    Full Text Available Abstract Background Sudan red compounds are hydrophobic azo dyes, still used as food additives in some countries. However, they have been shown to be unsafe, causing tumors in the liver and urinary bladder in rats. They have been classified as category 3 human carcinogens by the International Agency for Research on Cancer. A number of hypotheses that could explain the mechanism of carcinogenesis have been proposed for dyes similar to the Sudan red compounds. Traditionally, investigations of the membrane toxicity of organic substances have focused on hydrocarbons, e.g. polycyclic aromatic hydrocarbons (PAHs, and DDT. In contrast to hydrocarbons, Sudan red compounds contain azo and hydroxy groups, which can form hydrogen bonds with the polar head groups of membrane phospholipids. Thus, entry may be impeded. They could have different toxicities from other lipophilic hydrocarbons. The available data show that because these compounds are lipophilic, interactions with hydrophobic parts of the cell are important for their toxicity. Lipophilic compounds accumulate in the membrane, causing expansion of the membrane surface area, inhibition of primary ion pumps and increased proton permeability. Results This work investigated the interactions of the amphiphilic compounds Sudan II and IV with lecithin liposomes and live Escherichia coli (E. coli. Sudan II and IV binding to lecithin liposomes and live E. coli corresponds to the Langmuir adsorption isotherm. In the Sudan red compounds – lecithin liposome solutions, the binding ratio of Sudan II to lecithin is 1/31 and that of Sudan IV to 1/314. The binding constant of the Sudan II-lecithin complex is 1.75 × 104 and that of the Sudan IV-lecithin complex 2.92 × 105. Besides, the influences of pH, electrolyte and temperature were investigated and analyzed quantitatively. In the Sudan red compounds – E.coli mixture, the binding ratios of Sudan II and Sudan IV to E.coli membrane phospholipid are 1/29 and 1

  15. Present status and future trends of industrial radioisotopes application in Sudan

    International Nuclear Information System (INIS)

    Radioisotopes continue to play an important role in better management of natural resources, industrial growth and environmental preservation. The success of radioisotope applications is due primarily to the ability, conferred by the unique properties of radioactive materials, to collect data, where conventional methods fail or become uneconomical. These are prompt, on-line, in-situ and do not disturb the main industrial process in any way. In Sudan, the application of these nuclear techniques has considerable economic and environmental impact. This paper casts light on the present application of radioisotopes and future trends in the country.(Author)

Heavy metals contamination in cosmetic products is becoming an important health problem in both worldwide and locally at the level of the Kingdom of Saudi Arabia (KSA.The aim of this study was tostudy.Quantitatively estimated heavy metals “lead, cadmium, mercury and Arsenic” using graphite.Methods: total of 21 popular brands used lipstick products sold in Riyadh market samples from 3 different types of lipsticks frequently used among females in Saudi Arabia was digested. The digested samples were analyzed for lead, cadmium, mercury and Arsenic using graphite furnace- atomic absorption spectrometry. Results:the mercury concentration was high followed by arsenic and cadmium, finally lead. The results indicate that the toxic heavy metals in all the samples were below the US FDA and SFDA permissible limits for cosmetic products with the exception the mercury content in some lipstick samples was higher than SFDA. There was no significant difference among the lipsticks in price categories.Conclusion: Continuous use and possible unintended ingestion of these toxic heavy metals, though in low levels in the cosmetics, may pose potential health risk due to their bioaccumulation in body organs.

    Teucrium (Lamiaceae) is a large and polymorphic genus distributed mainly in Europe, North Africa and in the temperate parts of Asia. In this study, the anatomical features of the leaf and stem of Teucrium polium are investigated. Teucrium has 19 taxa in Iran, which mainly grow in the Irano-Turanian region between 700 and 2000 m above sea level. T. polium belonging to sect. Polium, is a perennial herb growing on Lorestan province. The leaves clearly exhibit xeromorphy due to features such as thick cuticle layer, thick outer epidermal cell wall, high density of trichomes and thick palisade layer of the mesophyll. Anatomical studies on T. polium revealed that the stem shares the general characteristics of the Labiatae family. The aim of our approach was to study the morphological and taxonomical parameters for T. polium in Saudi Arabia. The results of this study showed that there was no influence of environment on the structure of stomata and trichomes as studying species with T . polium. In conclusion our study shows we have studied the geographical distribution of the species in Saudi Arabia and in the world.

    Arabia is an important potential pathway for the dispersal of Homo sapiens ("out of Africa"). Yet, because of its arid to hyper-arid climate humans could only migrate across southern Arabia during pluvial periods when environmental conditions were favorable. However, knowledge on the timing of Arabian pluvial periods prior to the Holocene is mainly based on a single and possibly incomplete speleothem record from Hoti Cave in Northern Oman. Additional terrestrial records from the Arabian Peninsula are needed to confirm the Hoti Cave record. Here we present a new speleothem record from Mukalla Cave in southern Yemen. The Mukalla Cave and Hoti Cave records clearly reveal that speleothems growth occurred solely during peak interglacial periods, corresponding to Marine Isotope Stages (MIS) 1 (early to mid-Holocene), 5.1, 5.3, 5.5 (Eemian), 7.1, 7.5 and 9. Of these humid periods, highest precipitation occurred during MIS 5.5 and lowest during early to middle Holocene.
