Short-Term Feeding of Fibre-Enriched Biscuits: Protective Effect against Hepatotoxicity in Diabetic Rats

The effects of fibre-enriched biscuit on biomarkers associated with hepatotoxicity in diabetic rats were investigated. Diabetes was induced by single intraperitoneal injection of alloxan monohydrate. Treatment lasted for 14 days after which the rats were sacrificed by cervical dislocation. Blood serum was analyzed to determine hepatic function enzymes. The liver was also analyzed to determine hepatic lipid profile and antioxidant enzymes. Induction of diabetes led to elevated levels of ALP, AST, and ALT. These were, however, significantly (p<0.05) reduced in the fibre-enriched biscuit fed (treated) group. There was no significant difference in the serum bilirubin and total protein levels of the studied groups. Reduced albumin level was observed in the diabetic group; this was further lowered on feeding with fibre-enriched biscuits. Induction of diabetes led to increased hepatic level of cholesterol, triglyceride (TG), low density lipoprotein (LDL), and lipid peroxidation and decreased activities of glutathione (GSH), catalase (CAT), and superoxide dismutase (SOD) and HDL level. These were significantly (p<0.05) reversed on feeding with fibre-enriched biscuit. This study portrays the protective effect of fibre-enriched biscuit on increased oxidative stress and hyperlipidemia in hepatic tissues of alloxan-induced diabetic rats

Empowerment of women in Nigeria’s small-scale fisheries: a tool to sustainability

In Nigeria, women play major roles of at least 75% in the fisheries and aquaculture value- chains from production, processing, storage, marketing and trade. Unlike the men, women have not received commensurate levels of attention and empowerment largely because their roles are perceived as ‘invisible’, poorly evaluated and undocumented without substantial sex-disaggregated data as proof. For these reasons above and in furtherance of identifying key areas in which empowerment needs to be strengthened thus closing the gender gap, this study was undertaken to contribute to information on the nature and empowerment of women and the factors influencing their participation in the small-scale fisheries. The study also aimed at determining relationship between the extent of the women’s empowerment and some selected determinants using a cumulative empowerment index (CEI). A mix of transdisciplinary, quantitative and qualitative methods was used for this study in Ikosi in Agbowa and Igboolomi fishing communities of Epe and Ibeju-Lekki Local Government Areas of Lagos State respectively. Ten indicators of empowerment : contribution to household income, decision making ability, spending ability, ownership of assets, access to resources, membership in economic or social groups, time allocated to household, productive tasks and leisure activities, coping capacity to household shocks and political awareness were chosen for this purpose. Results obtained in this study showed that women are still very low in the CEI and it is hoped that this will pave way for a strategic framework for including gender –responsiveness in policies and developmental planning

Spatio-temporal variations in urban crime in Ogbomos, Nigeria

Against the background of the increasing frequency, scope and sophistication of crime as well as the insurmountable problems associated with its seemingly uncontrollable tendencies in cities of the world generally and Nigerian urban centers in particular, this paper examines the rates, forms and spatio-temporal variations in urban crime in Ogbomoso, Nigeria. The paper utilizes a nine-year (1995-2003) police crime record obtained from the Divisional Police Headquarters of the two local governments whose areas of jurisdiction cover the metropolis. A total of 4767 reviewed crime cases were reclassified into ten categories and examined by location within the existing urban spatial structure of high, medium and low density residential densities. All the ten categories of crime identified were encountered. However, the most prevalent were crime of acquisition (48.8%) and aggression (28.3%), with the high density area having the greatest concentration of cases. The temporal analysis shows that crime trend decreased in Ogbomoso within the period of study, a feat attributed to more gainful employment for the urban youths, particularly the increase in the use of motor cycle popularly known as “Okada” as a mode of intra-city transportation. The causal factors of crime are examined within structuralism and individualism paradigms. On planning implications, it is suggested that principles guiding landuse zoning (or allocation), infrastructural planning, and building design be reviewed so as to prevent the creation of danger zone within the urban landscape.

Modulation of lipid peroxidation, hypolipidemic and antioxidant activities in brain tissues of diabetic rats by fibre – Enriched biscuits

Objective: To investigate the effect of feeding fibre – enriched biscuit on the antioxidant and hypolipidemic activities in brain tissues of diabetic rats. Method: Diabetes was induced by a single intraperitoneal injection of alloxan. Treatment lasted for 14 d, after which the rats were sacrificed by cervical dislocation. Brain tissues were used for the assessment of GSH, catalase, SOD and lipid peroxidation as well as lipid profiles. Result: Induction of diabetes led to a significant decrease in GSH level, elevated SOD and catalase activities. These were significantly modified by the biscuits. There was an elevated level of malondialdehyde in the brain tissues of the untreated diabetic rats; this was significantly reduced by the biscuits. There was a significant decrease in HDL and a significant increase in LDL levels, total cholesterol and triglycerides in the untreated (diabetic) rats. Feeding with fibre – enriched biscuits led to decrease in the levels of total cholesterol, triglyceride, LDL – cholesterol and caused a significant increase in the levels of HDL. Conclusions: These results suggest a therapeutic and protective effect of the fibre – enriched biscuits against diabetic – induced brain toxicity in rats

Modulatory effect of fibre-enriched cake on alloxan-induced diabetic toxicity in rat brain tissues

Diabetes is a metabolic disorder characterized by hyperglycaemia and it is fast becoming a scourge in sub-Saharan Africa. The nutritional properties of developed fibre-enriched cake and its protective potential against diabetic induced neurotoxicity in rats were investigated. Fibre-enriched cake was developed from selected fruits and analysed for its nutritional and sensory attributes. Rats were induced with diabetes by a single intraperitoneal injection of alloxan and treated with the formulated cake. After 14 days treatment, the rats were sacrificed by cervical dislocation. Their brain tissues were accessed for reduced glutathione (GSH), catalase, superoxide dismutase (SOD) activities, protein content and lipid peroxidation as well as lipid profiles which cover for total cholesterol, triglycerides, HDL and LDL. Induction of diabetes led to significant reduction (p < 0.05) of GSH, catalase, SOD activities and protein content. Feeding on the formulated cake led to their significant increase. Decreased lipid peroxidation, total cholesterol, LDL and triglycerides, and increased concentration of HDL were also observed on feeding with the cake. These results indicate an antioxidant protective potential of the fibre-enriched cake against diabetic-induced brain toxicity. Thus, it can serve as an adjunct to dietary therapy for diabetes
