Effect of Lifting Time and Drying Method on Yield, Quality and Aspergillus Flavus Incidence on Rainfed Groundnut

Two experiments were conducted over a period of five years from 1985  to 1 989, at Elobeid Agricultural Research Station Farm to study the effect of lifting time and drying method on yield, grade, kernel moisture content and aflatoxin incidence of rainfed groundnut. A randomized complete block design with three replications was used. Seven lifting times were made at 10-day intervals, staffing at 80 days and continuing up to 140 days after planting. Four drying methods were tested, two traditional ones, in which the plants were stacked with pods placed in the centre of the heap or packed over each other, and the other two included inverted windrows with pods upward and a new suggested method in which plants were stacked with pods placed up exposed to direct sunlight and air current. Lifting time significantly (P=0.05) affected yield and its grade. Early lifting increased the percentage of immature pods and resulted in low yield of poor grade, while late lifting increased the underground losses and decreased intact yield. Significant (P=0.05( positive correlation was found between lifting time and pod infection with A. flavus. Higher A. flavus infection was observed at late lifting. The results of the drying method experiment indicated that the level of aflatoxin contamination varied from one season to another. In the new suggested method and the inverted windrow method, the drying rate is faster and the percentage of contaminated samples was lower than that of the two traditional drying methods. To obtain high intact yield of good grade and reduced aflatoxin contamination, it is recommended to lift the crop at 100-110 days from planting and dry it for 8 days by stacking the plants with pods placed upward, so as to expose the pods to direct sun-light and air current. &nbsp

Septic arthritis of ankle joint in the paediatric age group: a retrospective study

Background: Septic arthritis in paediatric age group poses a significant clinical problem. Common sites are hip and knee joint. There are several orthopaedic literatures available on septic arthritis of the hip and knee joint, however, literature on epidemiology, causative organisms and outcome of septic arthritis of the ankle are very few.Methods: We conducted a retrospective study at a tertiary hospital with an aim to evaluate the incidence, causative pathogen, outcome and to identify differences, if any, between clinical features and laboratory findings of these patients when compared to those with hip and knee joint infection.Results: 47 children were diagnosed with septic arthritis, of which, 14 had septic arthritis of the ankle. Mean age was 5.2 years (8 months - 12 years). 13 children had undergone joint aspiration as a primary procedure. 50% (7) children had positive culture. Streptococcus pyogenes was the commonest causative organism in our cohort (29%) followed by Staphylococcus aureus. Mean follow-up was 36 months (16 - 56 months). 13 children (93%) had good clinical outcome. 1 child developed early arthritis.Conclusions: Septic arthritis of the ankle is a serious condition. Even-though the joint is superficial, diagnosing it clinically can be difficult due to less pronounced symptoms. This can lead to delay in establishing the diagnosis and commencing treatment, hence, it is imperative to have a high index of suspicion. We found early joint aspiration followed by a course of antibiotics to be an effective regimen in management of this devastating condition

SELF-ASSEMBLING HYDROGELS BASED ON Î’-CYCLODEXTRIN POLYMER AND POLY (ETHYLENE GLYCOL) BEARING HYDROPHOBIC MOIETIES FOR PROTEIN DELIVERY

Objective: The development of injectable and stable hydrogels for protein delivery is a major challenge. Therefore, the objective of this study was to evaluate the potential of polymerized β-CD for the formulation of stable hydrogels suitable for loading and release of bioactive agents and to investigate the mechanism of hydrogel formation. Methods: Hydrogels based on the inclusion complexation of polymerized β-cyclodextrin and cholesterol terminated poly(ethylene glycol) polymers were formed by rehydration of a lyophilized mixture of both polymers. The mechanism of hydrogel formation was investigated via isothermal titration calorimetry, fluorescence spectroscopy and dynamic light scattering measurements. The release behavior of bovine serum albumin (BSA) as a model protein from the modified gels was explored. Results: Rheological analysis demonstrated that the prepared hydrogels had a viscoelastic behavior even at elevated temperature (> 37 ˚C). There are two competing mechanisms for hydrogel formation. The first mechanism is the inclusion complexation between cholesterol moieties and β-CD cavities. The second one is the self association of cholesterol modified PEGs. β-CD had the ability to dissociate the PEG-cholesterol associations. The quantitative and complete release of BSA was observed within 4 weeks. Conclusion: The polymerized form of β-CD, rather than native β-CD is essential for the formation of stable hydrogels. These results were supported by the ability of the modified hydrogel system for loading and release of BSA, making such hydrogel systems promising devices in drug delivery applications

Saving the Fundaments: Impact of a Military Coup on the Sudan Health System

Military coups are not uncommon occurrences, particularly in developing nations where political systems might be less firmly entrenched or still evolving. Developments of this nature can often have profound implications for the affected nation’s healthcare systems, both in the immediate aftermath and over the longer term. This paper narrates some notable consequences of political instability on the national health system, particularly placing them in the context of the military coup in October 2021 – emphasizing the context behind the political turbulence, its acute and direct consequences, and the possible long-term legacies of political shocks on the already overwhelmed health system. As a descriptive piece, this narrative does not only look at the impact of the military coup on hospitals, but considers the implications for the healthcare system as defined by the WHO, with particular emphasis on the impact of the coup on health funding from multi-laterals, service delivery, human resource availability, and supply chains in Sudan

Saving the fundaments: impact of a military coup on the Sudan health system

Military coups are not uncommon occurrences, particularly in developing nations where political systems might be less firmly entrenched or still evolving. Developments of this nature can often have profound implications for the affected nation’s healthcare systems, both in the immediate aftermath and over the longer term. This paper narrates some notable consequences of political instability on the national health system, particularly placing them in the context of the military coup in October 2021 – emphasizing the context behind the political turbulence, its acute and direct consequences, and the possible long-term legacies of political shocks on the already overwhelmed health system. As a descriptive piece, this narrative does not only look at the impact of the military coup on hospitals, but further considers the different dimensions of the healthcare system as defined by the WHO, therefore reflecting the wider implications on health funding from multi-laterals, service delivery, human resource availability, and medical and vaccine supply chains in Sudan

On beta-time fractional biological population model with abundant solitary wave structures

Abstract The ongoing study deals with various forms of solutions for the biological population model with a novel beta-time derivative operators. This model is very conducive to explain the enlargement of viruses, parasites and diseases. This configuration of the aforesaid classical scheme is scouted for its new solutions especially in soliton shape via two of the well known analytical strategies, namely: the extended Sinh-Gordon equation expansion method (EShGEEM) and the Expa function method. These soliton solutions suggest that these methods have widened the scope for generating solitary waves and other solutions of fractional differential equations. Different types of soliton solutions will be gained such as dark, bright and singular solitons solutions with certain conditions. Furthermore, the obtained results can also be used in describing the biological population model in some better way. The numerical solution for the model is obtained using the finite difference method. The numerical simulations of some selected results are also given through their physical explanations. To the best of our knowledge, No previous literature discussed this model through the application of the EShGEEM and the Expa function method and supported their new obtained results by numerical analysis

Towards a digitized and integrated health information system in Sudan: assessment of readiness at state level

Background: A strong health information system able to generate timely and accurate information is essential to ensure effective and efficient performance. Sudan’s health information system is still paper-based and characterized by fragmentation and verticality. Efforts to overcome this have led to development of an integrated system to digitize the health information. For this to succeed the 18 states in Sudan need to be evaluated and assessed to identify the gaps in capacity and readiness for such important change. The aim of this paper is to assess the capacity and readiness of the health information system in Sudan at state level for the digitization of the health information system.Materials and Methods: This is a cross sectional institutional based study conducted in 2014 targeting the health information units in the 18 states ministries of health in Sudan. Quantitative data was collected using a pre-tested checklist and analyzed using SPSS version 20. Qualitative data was collected through semi-structured interviews with state managers and analyzed using the evaluation matrix.Results: All states ministries of health had health information units but this was believed inadequate in 27.8% and 72.2% had units at locality level. Data analysis units were not present in one third of the states. Basic statistical training was done in 15 states. Internet services was available in 14 states but was scarce at locality level (16.7%). Annual reports though produced by 17 states, one third admit not reporting to higher levels in a regular manner.Conclusion: There is a need to strengthen the health information system at state level. Challenges of ICT infrastructure, capacity building and coordination need to be addressed. This needs collaborative work and political commitment.Keywords: Health Information System, states, digitizatio

Perceptions and Expectations of Medical Students towards the Quality of Educational Services offered at A Sudanese University: How Far is the Gap?

Background: Students are the primary customers of high education service, and are becoming more aware of their consumer rights and of gaps between their expectations of service delivery and the reality of services.Objective: of this study was to investigate medical students’ perceptions and expectations of educational services quality at X University in Sudan.Methods: One hundred ninety six registered medical students in the academic year 2013- 2014, were enrolled; sample was collected through convenience sample technique. The study was conducted by the use of Modified SERVQUAL questionnaire. SPSS version 20 was used for data analysis.Results: There was a negative mean score for quality gap in all dimensions of service quality. Students perceived tangibles as quality indicators of the service quality at university, and expect universities to have modern-looking equipment, so that staff can provide efficient service to them. There was a strong student concern about teaching staff promises regarding timetables and exam schedules to be fulfilled on time, which indicated the area of most concern amongst the respondents (gap score – 1.94). A clear communication problem regarding service delivery was inferred, as students perception towards solving their problems was very low (gap score -1.91).Conclusion: students’ perceptions of services delivered by X University falls below their expectations; that indicates student’s dissatisfaction. This large gap constitutes a great challenge to the administrators and educational policy makers, who are recommended to consider students feedback as a quality indicator in the quality assurance process.Keywords: medical student, quality education, Sudan
