Journal of Thyroid Research , 2011, DOI: 10.4061/2011/214924
Abstract: The present study evaluated the ameliorative effect of vitamin C on alteration in thyroid hormones induced by low-dose subchronic coadministration of chlorpyrifos (CPF) and lead (Pb). Forty Wistar rats were divided into 4 groups of 10 animals each. Groups I and II were administered soya oil (2?mL/kg) and vitamin C (100?mg/kg), respectively. Group III was coadministered CPF (4.25?mg/kg ~1/20th LD50) and Pb (250?mg/kg ~1/20th LD50), respectively. Group IV was pretreated with vitamin C (100?mg/kg) and then coadministered with CPF (4.25?mg/kg) and Pb (250?mg/kg), 30?min later. The regimens were administered by gavage for a period of 9 weeks. The marginal decrease in serum triiodothyronine and thyroxine and the significant increase in the concentrations of thyroid stimulating hormone and malonaldehyde in the group coadministered with CPF and Pb were ameliorated by vitamin C partly due to its antioxidant properties. 1. Introduction Man and animals are exposed to a “soup” of chemical contaminants in the environment, which directly or indirectly affect their health and well-being. Pesticides and heavy metals are the most common environmental contaminants because of their respective widespread use in agriculture and industries. Hitherto, most studies on these chemical contaminants have centered on the examination of one single agent and therefore, current understanding of the toxicity of many environmental toxicants/pollutants is based primarily on toxicity studies performed on laboratory animals exposed to a single toxic agent [1, 2]. However, the environment is heavily contaminated with many chemicals, which interact with each other in such a way that modify their toxic response in humans and animals. Organophosphate (OP) compounds are the most widely used insecticides accounting for 50% of global insecticidal use [3] while Pb is the most widespread heavy metal contaminants with wide applications [4]. Occupational and environmental Pb exposure continues to be among the most significant public health problems [4–7]. Due to their persistent nature in the environment and their toxicodynamics, CPF and Pb have resulted in deleterious effects in man and animals [8]. The toxicity of Pb remains a matter of public health concern [9] due to its pervasiveness in the environment and the awareness about its toxic effects [10] at exposure levels lower than what was previously considered harmful [11]. Reproductive consequences of Pb exposure are widespread [12], affecting almost all aspects of reproduction [13]. Pb induces decreased sperm count and motility and increased
Technology Enabled Customer Relationship Management in Supermarket Industry in Nigeria  [PDF]

Customer Relationship Management (CRM) is an enterprise-wide business strategy directed at attracting, retaining and effectively serving customers to grow up their value over the long term. Because customers differ in their preferences and purchasing habit, and their mobility is enhanced by increasing availability of information, firms invest in technologies that help them gain detailed understanding of their customers, allowing them to know how to respond to customer needs and market products and services more effectively. While the modern CRM strategy is intensive in the use of analytical technologies, the Nigeria supermarket industry still at the first stage of its development phase have largely interacted with customers through personal interaction partly due to the low level of competition for customers, high cost of investment in analytical CRM infrastructure and lack of dynamic capability to integrate technology, people and processes.

OA Sowande, O Adejuyigbe, AM Abubakar
Nigerian Journal of Surgical Research , 2003,
Abstract: Background: The management of cystic lymphangiomas is and challenging. Of all the available modalities of treatment, surgery remains the gold standard but it is associated with significant morbidity and mortality. Method: Retrospective analysis of 28 cases of cystic lymphangioma seen at the Obafemi Awolowo University Teaching Hospital, Ile-ife, Nigeria. Results: There were 16 boys and 12 girls with a median age of 6 months. The cervical region was most commonly involved site in 19(67.9%) children. Eight (28.6%) of the patients had morbidity at presentation. Only 24 of the 28(86%)patients had surgical excision. Complete macroscopic excision was possible in 15 (62.5%) patients. There was one death (4.2%) at induction of anaesthesia due to rupture of a cervical cyst at intubation with aspiration. Post-operative complications occurred in 10 (41.7%) patients. Recurrence was reported in 1(4.6%) patient. Conclusion: The presentation of cystic lymphangiomas in our own environment is diverse. There is a high preoperative morbidity. Surgery remains the only option available in this environment but is associated with a high e complication rate. (Nig J Surg Res 2003; 5: 32 – 37)
Germination and seedling growth of Acacia Senegal (l.) Willd and Parkia Biglobosa (jacq.) as influenced by salinity in Sokoto State Nigeria
International Journal of Forest, Soil and Erosion , 2013,
Abstract: An investigation was carried out on the seed germination and seedling growth response of two indigenous savanna tree species (Acacia senegal and Parkia biglobosa) to salt (NaCl). Soil samples from two plots within Dabagi research farm of Usmanu Danfodiyo University Sokoto were used. These samples were taken from Dabagi Upland 2 (DUP2) and Dabagi Lowland (DLL) at the depth of 0-30cm. The seeds were sown in the soil samples of 0.0dSm-1, 2.2dSm-1and 2.8dSm-1 salt levels and observed until complete germination, and growth parameters (height and collar diameter) were measured fortnightly for 12 weeks. It was observed that salinity influenced the germination of seeds of the species with A. senegal (54%) showing a better germination at 2.2dSm-1 compared with P. biglobosa (44%). Secondly, the tree seedlings showed significant differences in their growth over the period of the study. It was observed that on the whole when compared, P. biglobosa showed a significant difference at (P<0.05) between 0.0dSm-1 and 2.8dSm-1. The result indicated that P. biglobosa though a savanna species, does not thrive well in high saline soils and should not be used in agro-forestry plot deep in the savanna where irrigation water may tend to increase soil salinity.

O. Chukwu,B. A. Orhevba,I. Abubakar
Journal of Innovative Research in Engineering and Sciences , 2011,
Abstract: In this study, some physical and chemical properties of two cultivated varieties of guinea corn (brown and white) were studied. The physical properties are pericarp, colour, kernel size, 1000-kernel weight and moisture content. Standard laboratory procedures by Association of Official Analytical Chemists (AOAC) were followed to obtain chemical compositions such as oil, crude fibre, ash and protein from the two varieties of guinea corn. The results show that brown variety contains 5.03 % oil, 2.33 % crude fibre, 1.87 % ash and 10.80 % protein; while the white variety contains 3.03 % oil, 1.97 % crude fibre, 1.99 % ash and 10.00 % protein. Nitrogen free extracts were found to be 1.66 % and 73.97 % for brown and white samples, respectively. The amylose contents were 35.00% for brown and 21.67 % for white. Mineral contents such as calcium, potassium and phosphorus determined showed that the brown variety contains 0.14 % calcium, 0.19 % potassium and 0.16 % phosphorus while the white variety contains 0.27 % calcium, 0.21 % potassium and 0.12% phosphorus. The carbohydrate and energy values were obtained to be 72.12 % and 374.07 kcal/100g for brown and 73.98 % and 363.10 kcal/100g for white. From the results, even though the carbohydrate and energy values of guinea corn compare favourably well with those of other cereals, the mineral contents were lower than the previously reported values for cereals generally. Thus, in formulating animal feed or for human consumption it is recommended to mix the two varieties of guinea corn with protein rich foodstuff such as wheat or soyabean, so as to obtain the optimum dietary requirement needed by the body.

Case Reports in Clinical Medicine (CRCM) , 2014, DOI: 10.4236/crcm.2014.38106

Background: Guillain-Barre syndrome (GBS) is an autoimmune disorder characterized by a heterogeneous group of pathological and clinical entities. It is associated with ascending areflexic paralysis, some autonomic dysfunction and respiratory failure in severe cases and ultimately death if not promptly diagnosed and treated. It may be preceded by an antecedent event in about two-third of cases. This could be an upper respiratory tract infection, viral illness, recent history of vaccination, pregnancy, cancer or even trauma. The condition is exceedingly rare in pregnancy and only few cases have been reported in literature. Case Report: This is a case of a 28-year-old Gravida 3, Para 1+1 and Estimated Gestational Age of 30 weeks and 4 days. There was a history of upper respiratory tract infection eight weeks prior to presentation which spontaneously resolved. On examination, she was a young woman, anxious, weak, afebrile, not pale, the neck could not hold the head upright and there was bilateral non tender pitting pedal oedema extending to her mid-shin. There were no cranial nerve deficits and no sign of meningeal irritation. There were normal muscle bulk with global hypotonia and flaccid quadriparesis, Power was 3/5. The proximal groups of muscles were more affected than the distal parts. Reflexes were diminished globally with plantar flexor response. She had immunoglobulin as treatment. Conclusion: In a low resource setting like ours it is important to have a high index of suspicion of GBS when an apparently healthy gravid woman presents with progressive weakness of the limbs.

Natural Resources (NR) , 2014, DOI: 10.4236/nr.2014.51005

A review on the geology and petroleum potentials of the Nigerian Benue Trough and Anambra Basin is done to identify potential petroleum systems in the basins. The tectonic, stratigraphic and organic geochemical evaluations of these basins suggest the similarity with the contiguous basins of Chad and Niger Republics and Sudan, where commercial oil discovery have been made. At least two potential petroleum systems may be presented in the basins: the Lower Cretaceous petroleum system likely capable of both oil and gas generation and the Upper Cretaceous petroleum system that could be mainly gas-generating. These systems are closely correlative in temporal disposition, structures, source and reservoir rocks and perhaps generation mechanism to what obtains in the Muglad Basin of Sudan and Termit Basin of Niger and Chad Republics. They are very effective in planning future exploration campaigns in the basins.

Post Mortem Analyses of Mokwa Cattle Ranch, Niger State

Journal of Animal and Veterinary Advances , 2012,
Abstract: Mokwa Cattle Ranch (MCR) was established in 1964 specifically for fattening purposes, under a bilateral agreement between the German and Nigerian governments. It had full compliments of infrastructures, facilities and machineries at European Union standards and handed over to Nigeria in 1974. It was established to make full use of the molasses that is produced at the nearby Sugar Company at Jebba. Its total land area is 6,885 out of which 2,780 hectares have been prepared for grazing and cropping and 4,108 hectare remains as rangeland. With a capacity of 10,000, by 1973 its herd had attained 3,000 cattle. MCR carried out investigations in pasture establishments and its Green Panic grass of 200 hectares could be harvested six times in the rainy period and fed 3,000 cattle in 1973. Its feeding regimen for rainy seasons’ with natural pasture gave 0.300 and Green Panic 0.500 kilograms per day weight gain. Gross margin was N28.60 per animal per day. MCR has been facing systemic decadence and in 2004, it was closed again. The latest consortium that took over has stopped operations. Failures of MCR are attributed to: rising obsolescence, negative impacts of macro-economic instruments such as foreign exchange rates (limiting capacities to import spare-parts), inflationary pressures (costs of direct and indirect inputs), interest rates (costs of funds) and poor management capacities and its deliverance by Nigerians. It is recommended that the system of banks supervisions by the Central Bank should be imposed on boards of parastatals with visible and stringent sanctions` implications.

Tropical Journal of Pharmaceutical Research , 2010,
Abstract: Purpose: To characterize the aerial parts of Andrographis paniculata, a bitter Indian herb grown in Nigeria, for the purpose of quality control. Methods: The determination of bitterness value and of various physicochemical characteristics; tests for key phytochemicals; and thin layer chromatography (TLC) of the air-dried herb, were carried out as prescribed in standard texts. Results: The mean bitterness value of the herb for both men and women was 2.86 ± 1.74 x 103 units per g. The male value (2.07 ± 1.42 x 103) appeared to be lower than the female’s (3.52 ± 1.82 x 103) but the difference was not statistically significant. The results (% w/w) of loss on drying (10.64 ± 0.36), total ash (14.10 ± 4.49), water extractive value (30.37 ± 2.63) and acid insoluble ash (1.00 ± 0.06) were similar to those reported for the Asian plant. The phytochemical tests revealed the presence of glycosides, saponins, tannins and alkaloids, but not of anthraquinones. Normal phase TLC of the drug yielded 5 spots as against 6 spots yielded by reverse TLC. Conclusion: The results provide useful quantitative and descriptive data that are essential for identifying and characterizing the Nigerian grown herb for the purpose of quality control; and confirm key similarities between the Nigerian and the Asian plant.
