Nitroblue tetrazolium method used to estimate serum ...
Phytochemical investigation of fruit pulp of Adansonia digitata gave positive reactions for : steroids,terpenes,flavonoids,tannins and glycosides. GC-MS analysis of Adansonia digitataoil was conducted and the identification of the constituents was initially accomplished by comparison with the MS library (NIST) and further confirmed by interpreting of the observed fragmentation pattern.Comparison of the mass spectra with the database on MS library revealed about 90-95% match. The GC-M...
The QSAR model were successfully developed to calculate biological activity of 3, 5 di-substituted Pyrazoline derivatives as anticancer agents against AsPC-1 human pancreatic cell line and U251 human glioblastoma cell line, a good correlation models were obtained with R 2 =74.30% and R 2 =75.92% respectively, compounds (5-(4- bromophenyl)-3-(4-nitrophenyl)-4,5-dihydro-1H-pyrazole) and (N, N-dimethyl-4-[3- (4-nitrophenyl)-4,5-dihydro-1H-pyrazol-5-yl] aniline) were found to be the most�...
The aim of this study was to determine of nitrite ions (NO-2) in some locally produced, processed meats samples. Twenty three samples were obtained from the local markets in Khartoum state. The cured meat samples include Sausages, Martidala, Beef berger, Basterma, Hot dogs and Frankfurters. Nitrite ions were extracted from the samples by hot water. Nitrite content for each sample extract was measured by Uv-Vis spectrophotometry. Three samples showed nil nitrite content. Twenty samples ...
The aim of this research work was to study the potential capability of zeolites and kaolin to remove some, heavy, metals from drilling mud wastewater. Four samples were used, (three zeolites and one kaolin). Two natural zeolites(Stablite and Stellerite) collected from Al Gadaref state (East Sudan), synthesizedzeolite from fly ash using sodium hydroxide under hydrothermal conditions. Kaolin sample collected from Elmerkhiat mountain (North-East Omdurman Sudan). X-ray diffraction (XRD) w...
ABSTRACT There is an urgent interest initiated to develop clean energy resources with the aim of reducing exposure to environmental pollutants and explore model fuels that can hasten the achievement of clean energy combustion. In order to optimize the pyrolysis of binary transport fuels, diesel blends of ratios 1:1, 3:2 and 2:3 were each pyrolyzed at a contact time of 5 seconds in a quartz reactor at 1 atmosphere pressure, at a model temperature of 500 ºC. The surface morphology of the parti...
ABSTRACT Reuse of fluoride saturated bone char as a way of reducing fluoride in domestic water was investigated. The study was aimed at determining the most effective solution (NaOH, Na2CO3, NaHCO3 or Na3PO4) to use in the regeneration of fluoride saturated bone char. Effect of temperature on regeneration and removal capacity of regenerated bone char is also reported. Samples of 40 grams of bone char per 50 mL solution were used in determination of effectiveness of different sodium solut...
ABSTRACT Ganoderma polypore species are hard, leathery poroid mushrooms that lack the distinct stipe. They are a unique group of fungi usually ignored by most fungi enthusiasts because of their typical inedibility, unfamiliar habitat and general opacity. In addition to their traditional use, contemporary research has suggested many applications for cancer treatment and boosting of the immune system. Due to increase in bacterial resistance to existing antibiotics infectious diseases have ...
ABSTRACT Tea-drinking is a habit that has over time spread globally. The chemical composition of tea is very complex and is currently a subject of broad medical and toxicological scientific studies. Thus, the accurate quantification of the levels of both essential and non-essential elements in tea is very important in assessing it’s standard and quality as they are directly related to health and disease. This study examined the levels of Iron (Fe), Zinc (Zn), Copper (Cu), Lead (Pb), Cadmium...
Abstract The rise in the number of musculoskeletal disorders (MSDs) due to the increase in aging population and advancement in medical technology has led to an increasing demand for medication to prevent and treat these diseases. The development of new drugs or formulations to allow treatment of these diseases in their very early stages is only increasing. Local direct and multidelivery of medication and key minerals to support bone repair and regeneration at the defect site, from flexible de...
The presence of aromatics in fuel deters ultra-low sulfur fuel production. Consequently the researcher’s interest has involved the de-aromatization of fuels. Dearomatization would ultimately improve the quality of the fuels in terms of density, cetane number, viscosity etc. In this study, solvent extraction was adopted to de-aromatize a feedstock sample of 20.1 % aromatic and 166 ppm sulfur using acetonitrile. The extraction was performed at low temperatures 25, 35 and 45 °C and ambi...
The olefin metathesis was discovered incidentally and independently in 1950s by different researchers on their attempt to polymerize olefins by the Ziegler process [1-5]. The earliest discoveries were the basic exchange olefin metathesis of the inter-conversion of propylene, ethylene and butane-2 as well as ROMP of norbornene and cylcopentene. However, the connection between the two types of reactions was not immediately apparent mainly because different catalysts and conditions were generall...
This study aimed to measure concentration of selenium (Se) in five Sudanese fruits: Ziziphus spina christi (Nabaque); Adansonia digitata (Tabaldi);Balanites egyptiacea (Laloub); Grewia tenax (Gudeim) and Tamarindus indica (Aradeb). Se concentration was also measured in soil where the plant grows from different depths (75 cm ,100 cm and 150 cm). Also water sample was taken from nearby (Hafeer) to determine Se concentration. All samples were collected according to Standard Method of Sampli...
