Microenterprises have emerged as promising opportunities to eliminate poverty and create jobs. Microenterprises are confronted with many challenges such as accessing new markets and reaching out to customers. Along the same line, technology especially mobile phones have made significant contributions to business innovation and to the development of micro and small enterprises. The challenge of promotion and marketing are particularly acute for microenterprises due to their limited capabilities to initiate significant change without assistance. Thus the aim of this paper is to facilitate the communication between microentrepreneurs and customers through a call-centre that has -an easy phone number- using their mobile phone. The proposed call-centre is expected to orchestrate the interaction between microentrepreneurs and customers which will benefit both parties. Staff working at the proposed call centre will be able to create profiles for microentrepreneurs and link them through mobile phones with customers who are seeking skilled microentrepreneurs. This service is expected to help users as well as decision makers in their planning and development of micropenterpises. Source

Sorghum (Sorghum bicolor L.) is believed to be domesticated for the first time within the geographical range of Sudan, so, studying the genetic variation of sorghum genotypes collections attracts special interest. In this study, 17 sorghum accessions with important agronomic traits, representing four states in Sudan were assayed for polymorphism using Random Amplified Polymorphic DNA technique (RAPD). Ten primers out of 40 tested (A-1, B-20, C-20, D-18, OPE-04, UBC-101, UBC-103, UBC-127, UBC-155 and UBC-157) showed high polymorphism among the accessions. The results indicated 110 polymorphic bands out of 145 bands with percentage of polymorphic bands of 77.6%. Unweighted Pair Group Method with Arithmetic Mean (UPGMA) result showed two major clusters, with a clear trend of grouping of each region. A cluster contained all accessions from eastern Sudan (Red Sea). However, accessions from north Sudan (River Nile), western Sudan (North Kordofan) and south Sudan (Blue Nile) were diverse in another cluster. Based on the results of this study RAPD technique proved to be useful to study genetic variation among the Sudanese sorghum accessions. © 2013 Academic Journals Inc. Source

In Sudan, the prevalence of cancer cases increased and cancer ranked as the major cause of death. Therefore, forming a cancer control program and putting strategic action plans into practice became an important matter for the health industry. The correlation of variations in different societies and environmental factors should be examined spatially with reliable data. The aim of this study is to produce base maps for implementation of cancer control program and cancer density maps through the utilization of GIS in health work. In this study, a database was built with the use of GIS to examine the distribution of cancer cases and maps relating to cancer events in allocation units were created. Cancer cases data registered from 1999 to 2008, by the Institute of Nuclear Medicine and Molecular Biology and Treatment of Tumors-University of Gezira in El Gezira State, was used as case in this study. Using ArcGIS, the distribution of cancer cases were presented on cancer maps including allocation units and incidence values, which were calculated for each villages and locality region. According to the world standards, cancer rates were determined and examined by the spatial analysis power of GIS. The research concluded that cancer cases were increased, in some localities over the past 10 years (1999-2008). This can be related to many reasons including the existence of the Gezira Scheme were farmers used fertilizers and pesticides, as well as increasing health awareness among the citizens through the establishment of use in the state. © 2012 Springer Science+Business Media, LLC.

Aflatoxins are the most serious carcinogenic, hepatotoxic, teratogenic and mutagenic secondary metabolites which adversely affect human and animal health. This study was designed to evaluate the invitro inhibitory effect of different concentrations of Boswellia sacra resin (2.5, 5, 7.5 and 10g/100ml), leaf extract (5, 7.5, 10, 12.5 and 15ml/100ml), and essential oil (1, 2, 3, and 4ml/100ml) on the growth and aflatoxins production by two species of Aspergilli, namely Aspergillus flavus (SQU21) and Aspergillus parasiticus (CBS921.7). Resin of B.sacra caused 57.9-92.1% inhibition of aflatoxin secretion by A.flavus and 43.6-95.7% for A.parasiticus. However, the mycelial dry weights were significantly increased by 20.9-52.7% for A.flavus, and 8.9-68.5% for A.parasiticus. The leaf extract of B.sacra apparently enhanced aflatoxins production by 20-50%, and mycelial dry weight by 25.5-29.1% for A.flavus and A.parasiticus. The essential oil of B.sacra at different concentrations similarly inhibited the fungal growth and aflatoxins production by 45.8-83.7% for A.flavus and 41.3-83.5% for A.parasiticus which indicates the antifungal activity of this oil. None of the B.sacra extracts detoxified pure aqueous aflatoxin B1. We have concluded that B.sacra resin and essential oil possess biological activity against biochemical synthesis and metabolic pathway of aflatoxin production of the two Aspergillus species. Therefore, the resin and essential oil of B.sacra can be recommended as safe plant based bioreservatives to enhance shelf life of food and feed products with reference to adverse effect of physical and synthetic chemical preservatives and their antimicrobial and aflatoxins inhibition activity. © 2013 Elsevier Ltd.

Background: Helicobacter pylori is a common gut pathogen that is linked to many complications of pregnancy such as iron deficiency anemia, pre-eclampsia and thrombocytopenia. There are no published data on H. pylori in Sudan. Methods: A cross-sectional study was conducted during the period May-June 2012 at the antenatal care unit of Khartoum Hospital, Sudan, to investigate prevalence of H. pylori and its association, if any, with anemia and thrombocytopenia. Obstetric and medical histories were gathered using questionnaires. Hemoglobin and serum ferritin were measured and H. pylori antibodies (IgA and IgG) investigated using ELISA. Results: Among 179 women, rates of positivity for specific IgG formed against H. pylori were 69.8% (125/179), 94.0% (168/179) and 5.6% (10/179) for IgA, IgG and both IgG and IgA, respectively. There was no association between the expected risk factors (age, parity, education) and H. pylori seropositivity. Of these women, 42/179 (24.3%), 50/179 (28.9%) and 19/179 (11%), respectively, were anemic (hemoglobin <11 g/dl) or had iron deficiency (serum ferritin <15 μg/l) or iron deficiency anemia. There was no association between H. pylori infection and anemia (OR=1.0, 95% CI=0.3-3.2, p=1.0), iron deficiency (OR=0.6, 95% CI=0.1-3.8, p=0.367) or thrombocytopenia (OR=2.0, 95% CI=0.4-8.4, p=0.322). Conclusion: There is a high prevalence of H. pylori infection among pregnant women in Khartoum, Sudan, and it is not associated with anemia or thrombocytopenia. © The Author 2014.
