ABSTRACT Although molecular toxins and emission of particulates from the thermal degradation of biomass materials such as meat is a complex area of study, it has become necessary to investigate this phenomenon and determine how it affects biological functions and as precursors for cancer, degenerative diseases that stress the respiratory landscape. Accordingly, this study describes the pyrolysis of goat meat in the temperature range 300-525 ˚C. Goat meat sample of 10±0.2 g was heated under...
ABSTRACT Plants are a potential source of antimicrobial compounds. In this study, a plant from the family Simaroubaceae, Harrisonia abyssinica, traditionally used to treat a number of diseases was used. Research has been carried out on its stem bark, root bark and leaves and a number of chemical constituents have been isolated but no research has been carried out on its berries. Therefore the berries of this plant were chosen in order to investigate for antimicrobial compounds. The berries o...
ABSTRACT The botanical insecticides are generally pest-specific, relatively harmless to non-target organisms and biodegradable. Unlike conventional insecticides which are based on a single active ingredient, plant-derived insecticides comprise of an array of chemical compounds which act concertedly on both behavioural and physiological processes. Thus the chances of pest developing resistance to such substances are less likely. Essential oils are good example of plant compounds with such pro...
ABSTRACT The need for energy has risen greatly all over the world in recent years. One major source of energy is fossil fuel and most countries get access to this fuel through imports. Besides the rise in cost of fossil fuel, it has serious impacts on the environment which include air pollution and increased greenhouse gases in the atmosphere. Furthermore, this source of energy is nonrenewable and is quickly being depleted. Recently, attention has turned to environmentally benign and sustaina...
ABSTRACT Helminthic infections have severe consequences on the health of millions of people worldwide and cause serious economic losses. Synthetic drugs have been effective wormicides, however, they are expensive, show side effects and develop resistance. This has generated interest in the use of plant based anti-helmintics, which seem to offer a reliable, cheap and cost effective method. In this research, the anti-helmintic activity of secondary metabolites from Teclea nobilis and Rapanea m...
ABSTRACT The plant Tarchonanthus camphoratus belongs to Asteraceae family. Its common name is wild sage or camphor bush. This study was aimed at isolating bioactive phenypropanoid esters and sesquiterpene lactones from the leaves of this plant. A powdered sample of the leaves weighing 500 g was sequentially extracted with of hexane (1.5 L), dichloromethane (1.5 L) and methanol (3 x 1.5 L). The methanolic extract was partitioned between equal volumes (250 ml each) of distilled water. The n-but...
This study was conducted to estimate serum fructosamine and HbA1c in patients with type 1 and type 2 DM. 100 blood samples (50 type 1, 50 type 2) were collected from patients during period from February to April 2016, chosen randomly from health insurance – diabetic center and El-obied teaching hospital, and 50 apparently healthy individuals as control group to evaluate and estimate serum fructosamine and HbA1c in diabetic patients. 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 The synthesis and characterization of zeolite and its application in adsorption of nickel from aqueous solution was investigated. Synthesis of zeolite was performed at 90 oC for 8 h. The size of the resulting crystals increased with an increase in the water content of the reaction mixture. The synthesized zeolite was characterized by Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) techniques. Crystal structure of the product was determined as zeolite X by XRD. The...
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 ...
