Background: Most people exposed to M. tuberculosis show no evidence of clinical disease. Five to 10% of individuals with latent infection progress to develop overt disease during their life time. Identification of people with latent TB infection will increase case detection rates and may dictate new treatment policies to control tuberculosis. This study aimed to determine LTBI point prevalence in a population from Sudan using two different diagnostic methods: the tuberculin skin test (TST) and the IFN-γ release assay (IGRA). Methods. This was a prospective, community-based and case-controlled study. Following informed consent, household contacts (HHCs; n = 98) of smear-positive index cases and Community controls (CCs; 186), were enrolled. Tuberculin skin test (TST), whole blood stimulation with ESAT-6/CFP-10 ± TB7.7 antigens or purified protein derivative (PPD) and IFN-γ levels determination with ELISA were performed. The levels of IFN-γ and TST induration between the CCs and the HHCs were compared using student t-test, Chi-square and Kappa coefficient. Pearson correlation test was used to compare TST and IFN-γ. P levels of <0.05 were considered significant. Results: TST induration of ≥ 10 mm gave an LTBI point prevalence of 327 cases/1000 individuals among HHCs compared to 126 cases/1000 individuals among CCs (p = 0.000). PPD-induced IFN-γ release assay gave an LTBI point prevalence of 418 cases/1000 individuals among HHCs compared to 301 cases/1000 individuals among CCs (p =0.06). On the other hand ESAT-6/CFP-10 ± TB7.7-induced IFN-γ gave an LTBI point prevalence of 429 cases/1000 individuals among HHCs compared to 268 cases/1000 individuals among CCs (p = 0.01). IFN-γ productions levels induced by ESAT-6/CPF-10 ± TB7.7 antigens in HHCS and CCs were not significantly different from those induced by PPD (p = 0.7). Conclusion: IFN-γ release assay (IGRA) gave higher LTBI point prevalence compared to TST in HHCs and CCs. PPD gave comparable results to ESAT-6/CFP-10 ± TB7.7 antigens in whole blood IFN-γ release, making it a cheap alternative to the recombinant antigens. © 2013 Shakak et al.; licensee BioMed Central Ltd.

Cloud computing systems assist applications by offering virtualized resources that can be provisioned on demand basis. Computing resources are delivered by Virtual Machines (VMs). Traditional development models have many limitations such as cost and delay. Platform as services is an effective solution for most of problems on traditional development application model that faced by programmers as Platform as a Service provides them the same traditional features with a faster speed, reducing the cost and increasing collaboration. The aim of this paper is to develop cloud based framework based on Platform as a Services to assist in developing, testing and deploying application without the need to purchase of hardware, operating systems, and tools that is obtainable as services via the Internet. To evaluate the proposed framework, this study conducted an empirical study by setting up an experiment for programmers and IT 'specialists. The achieved results revealed that the proposed framework can overcome the tradition framework limitation © 2015 IEEE.

Grid-based Massive dataset search systems integrate many processes to search for a large number of shared datasets distributed over several locations. The implementation of the search mechanism to deal with these distributed dataset greatly affected the system performance. However, the execution of the search over the grid requires someone with grid knowledge and expertise. Consequently, this issue leads this research to propose an interface that hides the complexities of the grid operations from the end users. Additionally, the interface provides single sign-on mechanism to allow users to access several Virtual Organizations (VO) with a single user name and a password. The experiment was conducted to evaluate the user interface overhead and the efficiency of the interface. The result shows that the client user interface produces less overhead and is reasonably efficient in dealing with several VOs. © 2015 IEEE.

Laser-assisted atom probe shows a unique potential in the analysis of embedded Si/metal interfaces, owing to its ability to deliver 3D information with atomic resolution. The interface structures in tri-layer specimens Cu/amorphous Si/Cu are investigated by this technique. For amorphous Si (a-Si) deposited on Cu, a sharp transition occurred with an interface width of 2.4 nm. On the contrary, a much broader mixed zone, 5.3 nm wide, is formed when Cu is deposited on top of a-Si. Only in the latter case, brief annealing leads to immediate nucleation of the Cu3Si. Secondary neutral mass spectrometry confirmed independently the existence of this asymmetry in phase formation and demonstrates linear growth kinetics of the silicide. © 2013 WILEY-VCH Verlag GmbH & Co.

Distributed information retrieval methods are growing rapidly because of the rising need to access and search distributed digital documents. However, the content-based information retrieval (CBIR) is concentrated to extract and retrieve the information from massive digital libraries, which require a huge amount of computing and storage resources. The grid computing provides the reliable infrastructure for effective and efficient retrieval on these large collections. In order to build an effective and efficient CBIR technique, varieties of architectures were developed based on grid technologies. The goal of such architecture is to solve interoperability and heterogeneous resource issues, and increase the efficiency and effectiveness of information retrieval (IR) techniques by harnessing the grid computing capabilities. This paper reviews and analyzes latest research carried out in the domain of large-scale dataset IR based on a grid. The evaluation is based on scalability, response time, scope, data type, search technique, middleware, and query type. The contribution is to illustrate the features, capabilities, and shortages of current solutions that can guide the researchers in this evolving area.

Background: Schistosomiasis is one of the major communicable diseases of public health and socioeconomic importance in developing countries. This study assessed the situation of schistosomiasis among villagers of the New Halfa Agricultural Scheme, Sudan. Methods:An epidemiological survey was carried out in three randomly selected residential sites: Village 19, Village 26 and Talat shagrat Camp, from October to December 2013. Feces and urine samples were collected from 2433 individual (1195 male and 1238 female) and examined for schistosomiasis infection. The prevalence and intensity of infection were calculated according to study sites and participants’ sex and age-group. Results: There was no infection with Schistosoma haematobium among the examined individuals, while the overall prevalence of S. mansoni infection was 27.4% and the mean intensity among those infected was 261.1 eggs per gram (epg). A high prevalence and intensity of infection was found among the residents of Talat shagrat Camp, followed by the other two villages. The prevalence of infection among males was 41.4%, and among females was 13.9%. On the other hand, the intensity of infection among females was 293.4 epg and among males 187.6 epg. A high prevalence of infection was found in the age-groups 11-20 years and > 50 years. High intensity of infection was present in the age-groups 31-40 years and > 50 years. Conclusion: The finding of the study shows the need for an integrated control program against schistosomiasis. Mass treatment, provision of adequate clean-water supply and combating the intermediate snail host are suggested. © 2016, Tehran University of Medical Sciences (TUMS). All right reserved.

We analyzed the dietary composition of 153 specimens of the subdesert toad, Amietophrynus xeros, collected in the rainy and dry seasons in Shendi, Sudan. The dietary items in the toads included a wide variety of arthropod prey belonging to 10 orders: Hymenoptera, Coleoptera, Heteroptera, Diptera, Isoptera, Lepidoptera, Orthoptera, Acari, Araneae, and Lithobiomorpha. The most frequent prey items were insects of the order Hymenoptera and Coleoptera, during both the rainy and dry seasons. We found significant positive correlations between the snout-vent length of the toads and both the number and length of prey consumed, based on analyses of all toads and several prey orders. We did not find significant differences between male and female toads in the mean number or mean length of prey consumed during either the rainy or dry seasons. Likewise, we did not find significant differences between juveniles and adults in the mean number or mean length of prey consumed during the two seasons, even though adults averaged approximately twice as long as juveniles. © 2016.

Bladder cancer is one of the most common cancers in Africa. It takes several days to reach a diagnosis using histological examinations of specimens obtained by endoscope, which increases the medical expense. Recently, spectroscopic analysis of bladder cancer tissues has received considerable attention as a diagnosis technique due to its sensitivity to biochemical variations in the samples. This study investigated the use of Fourier transform infrared (FTIR) spectroscopy to analyze a number of bladder cancer tissues. Twenty-two samples were collected from 11 patients diagnosed with bladder cancer from different hospitals without any pretreatment. From each patient two samples were collected, one normal and another cancerous. FTIR spectrometer was used to differentiate between normal and cancerous bladder tissues via changes in spectra of these samples. The investigations detected obvious changes in the bands of proteins (1650, 1550 cm -1), lipids (2925, 2850 cm -1), and nucleic acid (1080, 1236 cm -1). The results show that FTIR spectroscopy is promising as a rapid, accurate, nondestructive, and easy to use alternative method for identification and diagnosis of bladder cancer tissues. © 2012 Springer Science+Business Media, Inc.

Absolute dependence on mecA gene as the defining standard in determining the resistance of S. aureus to methicillin became the subject of distrust by many researchers. The present study aimed to determine the frequency of mecA gene in methicillin resistant S. aureus (MRSA) isolates using polymerase chain reaction and to correlate its presence to conventional method. In this regard, two hundred S. aureus isolates were collected from patients with different diseases attending different hospitals in Shandi City, Sudan. Phenotypic Kirby-Bauer method confirmed the existence of methicillin resistant S. aureus in 61.5% of the subjected isolates with MICs ranging from 4 g/mL to 256 g/mL when using E-test. However, when amplifying a 310 bp fragment of the mecA gene by PCR, twelve out of the 123 MRSA isolates (9.8%) were mecA negative, whereas all the 77 methicillin sensitive S. aureus (MSSA) were mecA negative. In conclusion, this study drew attention to the credibility of the mecA gene and its usefulness in the detection of all MRSA strains without referring to the traditional methods. Hence, it is highly recommended to consider alternative mechanisms for -lactam resistance that may compete with mecA gene in the emergence of MRSA phenomenon in the community.
