The Diagnostic Value of the Glucose Curve in Individuals with and without Diabetes

Aim: Of this study is to demonstrate the importance of glucose curve test in monitoring pre and post-meal variation in diabetic and normal individuals.

Methodology: The individuals subjected to this study mainly grouped in two categories the (DM2 group) and the (Control group), they instructed to came fasting at which blood sample will be collected in EDTA and blank tube then after 30 min. the first post-prandial blood sample collected and then after every 1,2,3,4,5,6,7,8 hours blood sample collected subsequently, then serum separated from each sample (except the EDTA tube) analysed biochemically for glucose and glycated haemoglobin HbA1c (from EDTA tube).

Result: We found that, the calculated glucose based on mean glycated haemoglobin HbA1c% results underestimate the real concentrations all over the glucose curve in control group but in DM2 group it underestimate the mean and some actually measured concentration in some points of the curve which adds more burden on the diabetic patient and the responsibility of adjusting the dose and time of administration.

Conclusion: from our prospect we recommend the use of blood glucose curve as a monitoring and diagnostic tool generally for glucose metabolism in normal, pre-diabetic, diabetic and uncontrolled diabetic patients before and during therapeutic conditions.

Antiplasmodial, Hepatic and Nephritic Effects of Fractions of Methanol Leaf Extract of Glyphaea brevis in Plasmodium berghei-Infected Mice

This study evaluated the antiplasmodial, hepatic and nephritic effects of fractions of Glyphaea brevis methanol leaf extract in P. berghei infected mice. Mice weighing between 15-30 g were infested intraperitoneally with 0.2ml plasmodium infected blood and left for 3 hours before treatment. Infected test groups were treated via oral route of administration with varying doses (200, 300 and 400 mg/kg body weight) of ethylacetate, N-butanol and residual aqueous portion fractions of the Glyphaea brevis methanol extract and Artemisinin (5 mg/kg b.wt) for four days. N-butanol fraction showed the highest antiplasmodial activity (76.64%), followed by residual aqueous portion (73.25%) and ethylacetate (72.99%); Artemisinin has 86.13%. Serum bilirubin (total and conjugated) concentrations of the untreated group (0.82 ± 0.20, 0.51 ± 0.12) were significantly lower (P<0.05) than those in the infected group treated with 300 mg/kg of the residual aqueous portion (1.36 ± 0.20, 0.76 ± 0.05) respectively. Serum albumin levels showed significant (P<0.05) increase in all the groups treated compared to the positive control. Serum total protein, urea and creatinine levels of test groups were not significantly (P>0.05) different from the positive control group. Conclusively, Glyphaea brevis has substantial antiplasmodial activity and could provide a lead for new antimalarial drug development.

Haematological Assessments of Cocos nucifera Linn. Water and Oil on Apparently Healthy Wistar Albino Rats

In this study, the effects of the consumption of Cocos nucifera L. water and oil on the haematological parameters of apparently healthy wistar albino rats were investigated using standard methods. The albino rats (n= 100) were divided into 8 groups (A-H) of 12 rats each while the remaining four rats were put in another group to serve as control. The first four groups(A-D) were daily orogastrically administered different volumes of coconut oil, 0.5 ml, 1.0 ml, 1.5 ml, 2.0 ml respectively for 4 weeks while groups E-H were daily orogastrically administered different volumes of coconut water, 0.5 ml, 1.0 ml, 1.5 ml, 2.0 ml respectively for four weeks. The control rats (Group l) however were not administered either coconut water or coconut oil. All the rats were allowed free access to rat chow and water. The administration of either of the coconut water or oil caused a significant increase (p≤0.05) in the PCV, WBC and the differential leukocytes counts within the four weeks of this study with coconut water having higher effect. It is conceivable that the consumption of either coconut water or coconut oil could exert both hematinic and immuno-stimulatory effects in the consumers to checkmate low PCV and also boost innate immunity.

Influence of Soil Arsenic Levels on Biomass Production and Relationship the Concentration of Arsenic between Rice Straw and Grain

Arsenic (As) contamination is widespread in Bangladesh. It can cause health hazards depending on consumption of foods grown on As contaminated soil. Two pot experiments were conducted at net house, Department of Soil Science, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur to study the effect of As on above ground biomass of different rice genotypes and to determine the relationship of As concentration between rice grains and straw. Sixteen rice genotypes were grown in pots soils having 0, 20, 40 and 60 mg/kg As both in winter and wet seasons. Soil As levels reduced above ground biomass of rice by 8-65%. Above ground biomass reduction was the least in BRRI dhan47 with variable soil As levels. Total As concentrations in straw and grains increased with increasing soil As levels. Moreover, the concentration of As in rice grain was also increased with greater As concentration in straw. Grain to straw ratio of As concentration was lower at higher As concentration in straw. It is indicated that reduced movement of As from rice straw to grain take place when straw As concentration was high.

Study of the Output Electric Parameters of the Sub-cells Composing the Ga0.67In0.33P/GaAs/Ga0.70In0.30As Triple-Junction Photovoltaic Cell and its Performance in Real Environment:Cases of Bujumbura and Bugarama in Burundi

Multi-junction photovoltaic cells composed of III-V semiconductor materials are widely used in photovoltaic systems. They offer very high efficiencies compared to single-junction photovoltaic cells. Knowledge of the behavior of their electrical parameters in real operating conditions is essential for their best use. This work presents an analytical model for predicting the behavior of the output electrical parameters of the sub-cells composing the Ga0.67In0.33P/GaAs/Ga0.70In0.30 As triple junction photovoltaic cell, operating under the actual conditions of two selected sites. The dependence of the external quantum efficiency at the wavelengths corresponding to the absorption ranges of the top (Ga0.67In0.33P), middle (GaAs) and bottom (Ga0.70In0.30As)$$ sub-cells is analyzed and discussed. The influence of temperature and irradiation on the V oc ,J sc, F F and η parameters is discussed taking into account the meteorological characteristics of two selected locations. An average daily conversion efficiency of the Triple-Junction solar cell of 37.24% and a daily electrical power of 1613.1 W/m2 for the typical day(TD) of the sunniest month of the Bujumbura site were found. Similarly, under the same conditions, for the Bugarama site, we found an average daily efficiency of 37.28% and a daily electrical power of 1619.7 W/m2. The developed model can also be used to design a more suitable Photovoltaic system at any specified place, provided that local weather data is available.

The Impact of Working Capital Management on Profitability of Global Haulage Company, Ghana

The study examines the impact of working capital management on profitability of Global Haulage Company Limited in Ghana. The service sector, which Global Haulage Company Limited forms part accounts for about 51% of national output and this show how vital the service sector has become in terms of job creation and gross domestic product growth in the Ghanaian economy. This study therefore employed the autoregressive distributed lag (ARDL) technique to examine the relationship between working capital management and profitability of firms in Ghana using Global Haulage Company Ltd as a case study with a period range of 1995 to 2013. The regression results showed that debt ratio, firm size and current assets to total assets ratio are negatively related to firm profitability whilst current liabilities to total assets ratio is positively related to firm profitability. The study therefore recommends that, management should use less of debt in financing their activities to be able to increase profit since high debt ratio adversely impact on profitability. Also, aggressive working capital policies should be pursued if management’s goal is to increase profit. In addition, policy makers should check and work on the managerial inefficiencies which are making the firm experience diseconomies of scale.

Influence of Environmental Heterogeneity on the Species Composition, Species Richness and Species Abundances Unevenness in Reef-associated Conus Communities (Neogastropoda) from Papua New-Guinea

To what extent differences in species composition, species richness and species abundance unevenness between marine communities are attributable to heterogeneities of the surrounding environment and/or to inter-community distance is a fundamental issue to be addressed, in order to more deeply understand the functioning of marine ecosystems. A comparison between six reef-associated Conus communities, differing more or less in both their surrounding environment and their mutual geographical distance, offers a relevant opportunity to address these questions.

As expected, environmental heterogeneities prove having a significant influence on the dissimilarity in species composition, whereas distance-decay in similarity reveals comparatively negligible, at least within the investigated range of distances, up to 60 km. Less expectedly, more homogeneous surrounding environments between communities tend, here, to increase the dissimilarity in species richness. At last, here, difference in species abundance unevenness between communities seems unrelated to either environmental heterogeneity or inter-community distance.

From a methodological point of view, these results could not have been reliably established without the prior implementation of a least-biased procedure of numerical extrapolation applied to the available incomplete samplings. Also, the relevant assessment of dissimilarity in species composition required using a modified Jaccard index, rendered insensitive to bias-induced differences in communities species richness.

Hyperglycemic and Hypocholesterolemic Effect of Monosodium Glutamate in Wistar Rats

Background: The use of seasonings to enhance the flavor of food has been on the increase in recent times. Different types of seasonings are produced daily and the constituents of these flavor-enhancers are unknown to ignorant consumers. They only want to eat food with good taste without consideration of the effect of these additives on their health. These seasonings contain monosodium glutamate (MSG) which really spiced the food.

Aim: This study sought to investigate the effect of MSG on blood sugar and cholesterol.

Place and Duration: This research was carried out at the Department of Pharmacology and Therapeutics, College of Medicine and Health Sciences, Abia State University, Uturu, Nigeria in 2011.

Methods: Forty Wistar rats were used for this study. Fifteen of the rats were used for acute toxicity test (LD50) and twenty-five for the experiment. The 25 Wistar rats were divided into five groups of 5 rats each. Animals in groups A, B, C, and D were respectively administered 500 mg/kg, 750 mg/kg, 1000 mg/kg and 1,250 mg/kg of MSG thoroughly mixed with standard feed for eight weeks. Animals in group E received equal amount of feeds without MSG added. This group served as the control group. At the end of 8 weeks, animals were fasted overnight and anaesthetized using diethyl ether. Blood samples were collected by cardiac puncture into plain test tubes and allowed to clot. The clotted blood was centrifuged at 4000 rpm for 10 minutes in a centrifuge. Serum was collected and analyzed immediately (for glucose) and the remaining refrigerated for further analysis (cholesterol) using standard methods.

Results: The LD50 was taken to be 500 mg/kg, which is the median of 200 mg/kg which did not kill any of the animals and 800 mg/kg that killed all its animals. MSG was observed to increase blood glucose but decreased cholesterol when compared with control animals.

Conclusion: The elevation of blood sugar by MSG is an indication that it can induce diabetes.

Study design: A Retrospective study.

Purpose: To determine the clinical and radiological outcome of thoracic tuberculous spondylodiscitis through anterior transthoracic approach.

Methods: We retrospectively reviewed 38 patients with thoracic tubercular spondylodiscitis in our hospital between January 2010 to December 2016. The indication for surgery was the neurological deficit and refractory cold abscess not responding or worsening with antitubercular chemotherapy, spinal instability, and kyphotic deformity > 40°. All patients underwent surgery by the anterior transthoracic approach and had debridement, decompression, rigid fixation, and placement of bone autograft.  All the patients were evaluated clinically and radiologically on each follow-up. Frankel grading and VAS score were calculated.

Results: Total 38 patients in which 13 males and 35 females with a mean age of 45.02 years, a mean follow up of 47.84 months were included in our study. Preoperative neurological deficits were present in 34 patients out of which 31 patients improved, 2 remained the same after surgery according to Frankel grading and one mortality took place on the 8th postoperative day due to acute myocardial infarction.  Average VAS score was 7.4 at admission which was improved to 3.2 at final follow up. Preoperative kyphosis in the thoracic spine was 42.2º (22º-54º), which was corrected to mean of 25.3º (14º-29º) postoperatively. One patient developed chest infection one month after the surgery for which left sided pneumenectomy was done. There was no graft and implant-related complication.

Conclusion: Treatment of thoracic tubercular spondylodiscitis with anterior transthoracic approach provides adequate debridement thorough decompression of the neural tissue with good deformity correction and also achieves good clinical, neurological, radiological and serological outcomes.

Granulometric and Mineralogical Characterization of Port-bouet Beach (Côte d’Ivoire)

Granulometric analysis of sampled sands along Port bouet coastline, during both periods (turbulent and calm periods), shows a wide particle size spectrum ranging from fine sand to very coarse sand. It should be noted, however, that the coarse fraction is largely predominant, particularly in channel proximity. This trend continues during both periods, caused by a grain size selection resulting from west-east direction coastal drift. Study of heavy minerals shows a very uniform mineralogical cortege, largely dominated by quartz, biotite and feldspaths. These minerals would come essentially from erosion of continental shelf granites. They are distributed along the coast by a coastal drift in a west-east direction. Study of sands transport mechanisms, collected on Port Bouet coast during the two seasons, May and November shows three modes of transportation: loading for very coarse sands, saltation for medium and coarse sands, and suspension for finer particles. Saltation is the mode of transport that predominates in all sectors, regardless of the observation period. Rates vary between 80 and 90% depending on the sector. Sediments transported by suspension and loading generally do not reach 12%.

Dietary Inclusion of Fermented Parkia in Feeds as an Organic Strategy to Improve Feed Quality and Antioxidant Parameters of African Catfish (Clarias gariepinus) Fingerlings

Aim: The aim of this study is to assess fermented parkia infusion in feed as organic strategy to improve feed quality and immune system of African catfish (Clarias gariepinus) fingerlings.

Place and Duration of Study: Department of Biochemistry, Ibrahim Badamasi Babangida University, Lapai, Niger State, Nigeria, between 1st January 2017 and 25th March 2017.

Methodology: In the present study, feed ingredients were fermented for 72 hrs with probiotic starter culture from Parkia biglobosa (TF diet) in comparison to a control diet with similar ingredients to the experimental diets but totally unfermented (CF diet) and used to make feed pellets. The experimental feeds were fed at 5% of body weight of each dietary treatment to triplicate groups of 20 fish per tank (100 Liter capacity), two times daily for 10 weeks. Proximate composition and mineral content of diets and whole fish, Feed efficiency, growth performance and Biochemical parameters of the fish were evaluated.

Results: The result of proximate compositions of experimental diets revealed a significantly higher protein and ash contents in TF compared to the CF. Carbohydrate content was significantly lower in TF diet while crude fibre, moisture and fat contents were not significantly higher in CF compared to TF. The highest values of some minerals such as sodium (Na), potassium (K), phosphorus (P) and magnesium (Mg) were also recorded in the TF while the least was recorded in CF. The result of feed efficiency and growth performance indicated similar feed acceptance and intake between fish fed the fermented diet and the control. The activities of serum antioxidant enzymes activities of superoxide dismutase and catalase were significantly (P < 0.05) higher in serum of fish fed TF compared to that in fish fed CF diet.

Conclusion: It can be deduced from this study that the fermented diet improved the immunity of fish and does not adversely affect the growth performance.

Jeans Instability of Fine Dust Particle with Impact of Coriolis Force, Electrical Resistivity and Electron Plasma Frequency

The present paper deals with the theoretical investigation of the combined influence of Coriolis force, electrical resistivity, electron plasma frequency and fine dust particles on the linear Jeans instability of gaseous plasma by using the generalized magneto-hydrodynamic fluid model. The general dispersion relation is derived using normal mode analysis technique and reduced for both the longitudinal and transverse mode of propagation and further, it is discussed of the axis of rotation parallel and perpendicular to the magnetic field. We found that the stabilizing influence of Coriolis force and electron plasma frequency increases for a fine dust particle, but electrical resistivity has the destabilizing influence on them. The Jeans criterion of instability is modified by fine dust particle only transverse mode of propagation when rotation is perpendicular to the magnetic field. The Coriolis force and electron plasma frequency have stabilized the growth rate of the system but the electrical resistivity is destabilizing the system. These results are applicable to interstellar clouds and star formation region.
