Abstract: Field experiments were conducted in September 2006 and March 2007 on two soil types  loamy sand (Ondo town) and clay soil (Bagbe town) in forest zone, southwest Nigeria to study the effect of cocoa pod ash (0, 5 and 10 t ha-1), NPK 20:10:10 fertilizer (0, 150 and 300 kg ha-1) and cocoa pod ash rates combined with 150 kg ha-1 NPK 20:10:10 fertilizer on soil chemical properties, plant nutrient content, growth and fruit yield of tomato. Mean data for 2006 and 2007 were use to compare the treatment means. The treatments were arranged on randomized complete block design and replicated three times. The experiment was repeated in the second year on the same locations. The soil at Ondo was deficient in soil OM, N, P, K, Ca and Mg while Bagbe was fairly adequate for crop production. Cocoa pod ash combined with NPK fertilizer significantly (p<0.05) increased soil OM, P, K, Ca, and Mg than single application of cocoa pod ash and NPK 20:10:10.  Fertilizer combinations also increased plant N, P and K at the two locations than single application of cocoa pod ash and NPK fertilizer significantly. 10 t ha-1 of cocoa pod ash combined with 150 kg ha-1 of NPK fertilizer gave the highest fruit yield at the two locations (89 % for Bagbe and 110 % for Ondo). The combined application of cocoa pod ash with reduced level of NPK fertilizer was more effective in increasing soil nutrients and fruit yield of tomato than cocoa pod ash and NPK fertilizer applied individually in loamy sand and clay loam. The trend in the yield showed that loamy sand utilized cocoa pod ash applied alone or combined with NPK fertilizer more than clay loam [New York Science Journal  2010; 3(4):1-11) (ISSN 1554 – 0200)

ABSTRACT: Field experiment was conducted at two locations in Lagos State, Ikorodu (Orthic Luvisol) and Lagos State (LASU) Ojo Campus (Dystric Fluvisol) to investigation the effects of organic, organomineral and NPK fertilizer treatments on the yield  of Amaranthus cruentus L. Eight fertilizer treatments: Control (no fertilizer), Pacesetter’s Grade B (PGB) 100 %, PGB + NPK (75:25), PGB + NPK (50:50), Kola Pod Husk (KPH) 100 %, KPH + NPK (75:25), KPH + NPK (50:50) and NPK (100 %).  Residual effects of fertilizers were assessed in the second and third planting periods.  All the experiments were arranged in a randomized complete block design in four replications.  Parameters assessed include plant height, number of leaves fresh and Dry Matter Yield (DMY).   Data were analyzed using ANOVA. The yields obtained were in the order of KPH + NPK (75:25) > PGB + NPK (75:25) > KPH (100 %) > PGB + NPK (50:50) > KPH + NPK (50:50) > PGB (100%) > NPK (100%) > control. Compared to the control, application of KPH + NPK (75:25) and PGB + NPK (75:25) had significantly (p< 0.05) higher DMY (200.1 % and 250.2 %) at Ikorodu and LASU respectively. This was because soils in Ikorodu (sandy clay loam) have high retentive capacity ) than that of LASU (sandy loam). At Ikorodu, KPH + NPK (75:25) was the best while at LASU, PGB + NPK (75:25) was optimum. [New York Science Journal  2010;3(4):12-17] (ISSN 1554 – 0200).

Abstract: The total bacterial load in fermented Cucumeropsis manii (Naud); Citrullus lanatus (L) and Colocynthis vulgaris (Schrad) ranged from 2.12 x 108 to 2.15 x 108; 1.35 x 108 to 2.00 x 1010 and 2.05 x 108 to 2.10 x 1010 cfu/g respectively. Six bacterial species were isolated from the fermented products which were tentatively identified to belong to the genera: Bacillus, Micrococcus, Leuconostoc, Streptococcus, Pediococcus and Lactobacillus. The proximate composition of both fermented and unfermented samples of the three melon seeds were determined. Results showed that unfermented samples had higher amounts of dry matter (91.9 to 93.4g/mg) and crude fiber (2.61 to 3.85g/100g) than corresponding fermented products. The ash content decreased in the fermented samples, except in Colocynthis vulgaris. Fermented samples had higher amounts of moisture and carbohydrate; a higher pH and titratable acidity during fermentation. Potassium was the predominant mineral in the samples. It ranged between 1075.00 and 1834.42 mg/100g of dried fermented samples. The fermented products were challenged with four pathogenic organisms: Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus and Klebsiella sp. The results indicated a prebiotic potential of freshly-fermented ‘ogiri’ against some of the pathogens. [New York Science Journal. 2010;3(4):18-27]. (ISSN: 1554-0200).

Abstract: The effect of water-steam transition temperature on the evaporation of water and shrinkage of clay during oven drying of clays has been studied. The investigation was carried out over a range of drying temperature and time; 80-1100C and 30-130 minutes respectively. The results of the investigation indicate that evaporation of water and shrinkage of clays are lowest at the water-steam transition temperature (1000C) compared to drying temperatures: 80, 90 and 1100C due to repeated reversible transition of state between water and steam at this temperature (1000C) within the clay-surrounding interface, resulting to absorption of the condensed water by the clay matrix. This is in agreement with the boiling characteristics of water at 1000C.The condensation process at this temperature increases and decreases the masses of water in the clay and that lost through evaporation respectively.

Abstract: The etiology of some oxidative-stress based pathological conditions in the liver has implicated excessive alcohol consumption. The present study therefore, is directed at investigating the effect of ethanol (found in alcoholic drinks) on selected markers of oxidative stress/damage. The effect was assessed on the basis of comparative levels of   MDA, GSH and GST in rats vis-a-vis experimental group treated with ethanol. Ten male albino rats of Wister strain, body weight range of (166 – 170) grams were treated with 5g ethanol (20%v/v) per kg body weight per day for 28 days along side with ten male untreated rats. Both groups were fed normal feeds and water ad libitum. The administratison of ethanol was done orally using oral catheter. Biochemical analysis at the end of the administration  of ethanol at a dose of 5g/kg body weight, caused  significant increase (P<0.05) of  the hepatic, renal and intestinal concentrations of malondialdehyde (MDA) by 109.96%, 84.42% and 37.60% respectively, compared with control. Similarly, the hepatic, renal and intestinal GST activities were significantly increased (p<0.05) by 112.29%, 85.76% and 80.96%respectively. The levels of reduced glutathione (GSH) in the liver, kidney and intestine of ethanol-treated animals significantly decreased by 66.72%, 50.36% and 56.67% relative to the control group. A lower mean body weight gain was observed in rats treated with ethanol as compared with control. Overall, the results of the study suggest that alcohol in chronic doses induces oxidative stress in the rats with implication of dangerous effects on humans if consumed at chronic doses.

Abstract: Starches, fabricated from fresh cassava cultivars TMS series 4(2)1425, 91934, 30001, 30555 and Odongbo, were analysed for their % yields, granular structures, granule sizes and distribution, proximate composition, chemical composition and physico-functional properties. TMS 91934, with the highest moisture content (MC) [65.0%] produces the least  starch yield [13.86%]  compared with TMS 30001 with 58% MC & 24.68% starch yield, TMS 1425 with 61.0% MC &19.68% starch yield, TMS 30555 with 60.5% MC & 20.13% starch yield, and odongbo (local cultivar) with 59.0% & 21.19% starch yield.  All the starches from these cassava cultivars exhibit similarities in their granular structures being oval/round, some truncated. Other observed features are: granule sizes ranging from 11.25”m in TMS 4(2)1425 to 15”m in TMS 91934; high dry matter (87%), low phosphorus (0.01 – 0.03%); low crude protein (0.18 – 0.88%); low ash (1.0%); pH 5.15 value; low water activity (aw) of 0.51 – 0.67; bulk density of 0.81 – 0.82; non-ionic characteristic; nil cyanide content, and salivary amylolysis of the starches, showing TMS 30001 and Odongbo to be more enzyme resistant than other starches. The swelling of water slurries of the starches is temperature dependent.The higher the temperature, the greater the swelling capacities of the starches. [New York Science Journal 2010;6(3):48-53].

Abstract: The number of obese children has increased considerably worldwide and childhood obesity causes many problems that can track into adulthood. The current study was conducted on 45 obese girls [mean age±SE =10.53±1.29 years; mean BMI±SE =28.43± 4.62 Kg/m2] in addition to 45 age- and sex-matched controls (mean age±SE =10.36±1.53 years; mean BMI±SE =19.07±3.47 Kg/m2). Estimation of serum ghrelin and growth hormone (GH), plasma leptin, insulin, and insulin-like growth factor-1 (IGF-1) as well as learning ability and cognitive functions (auditory vigilance, digit span, coding ability and visual memory) were carried out. The levels of plasma leptin, insulin and IGF-1 were highly significantly higher whereas those of serum ghrelin and GH were highly significantly lower in the obese group than the control. The total right response of auditory vigilance (TR) showed insignificant decrease while the total wrong response of auditory vigilance (TW) showed significant increase in the obese group as compared with the control group. Digit span showed highly significant decrease while coding scores showed significant increase. Visual memory recall showed insignificant decrease while visual memory classification showed highly significant decrease in the obese group as compared with the control group. Ghrelin decreased because of hyperinsulinemia and hyperleptinemia. Increased leptin level may be due to increased amount of adipose tissue in obese subjects. Hyperinsulinemia occurs to compensate for insulin resistance occurring in obesity and to maintain glucose homeostasis. The decrease in GH may be due to low GHRH, high somatostatin and increased free IGF-1 levels. Increased IGF-1 in obese subjects may be a result of hyperinsulinemia. Obesity in school girls negatively affected the levels of the measured hormones as well as the educational achievements of these girls which reflect the impact of obesity on cognitive performance and learning ability in these subjects.

Abstract: An investigation has been made to ascertain the metals concentration in the effluents and associated soil and groundwater samples collected from textile and tannery industries located near Haridwar. The physico-chemical analysis for metallic parameters was conducted by using Atomic absorption spectrometer (AAS) and spectrophotometer. The results showed that all metals such as Cr, Fe, Mn, Cu, Pb and Cd exceeded the standard limits in effluents of textile and tannery industries and associated soil samples, while Cr contamination in groundwater samples was observed only in samples collected from nearby areas of tannery. The findings also indicate that the Cr contamination was more than other metals. The estimated metal levels in the water and soil were compared with the safe limits laid down by World Health Organization (WHO). [New York Science Journal 2010;3(4):82-89]. (ISSN: 1554-0200).

Abstract: In the recent past a human-powered process machine has been developed for brick making, wood turning, clothes washing and drying and earthen pot making. The machine consists of a human-powered flywheel motor using a bicycle-drive mechanism with speed-increasing gearing and a flywheel, which drive the process unit though a spiral jaw clutch and torque-increasing gearing. The operator puts energy into the flywheel at a convenient power level for about one minute. After enough energy is stored, pedaling is stopped and the energy in the flywheel is made available to the process unit. Pedal power is the transfer of energy from a human source through the use of a foot pedal and crank system. This technology is most commonly used for transportation and has been used to propel bicycles. Less commonly pedal power is used to power agricultural and hand tools and even to generate electricity. The paper discuss about the applications for pedal power technology. The machine is economically viable, can be used by unskilled workers, save time otherwise spent in traditional mixing and can be adopted for human-powered process units which could have intermittent operation without affecting the end-product.

Abstract: Psoriasis, a common skin disease in Egypt, has drawn much attention to study the potential  role of immunity  in  its pathogenesis.. Exposure of skin to microbial antigens and other stressful stimuli can induce heat shock proteins (HSPs) expression. HSPs comprise a large number of antigens against which immune responses are directed, owing to their cytokine-like effects and immunomodulatory properties. The potential role of HSP70 in pathogenesis of psoriasis is under investigation. We aimed at evaluating the  differential immunohistochemical expression of HSP 70   in psoriatic skin and correlating the results with disease severity ; to elucidate its potential role  in pathogenesis of psoriasis. Skin biopsies were taken from 20 patients with different severity of untreated chronic plaque-type psoriasis and from 20 healthy volunteers. Antibodies to HSP70 were analyzed immunohistochemically. Immunoreactivity intensity distribution index (IRIDI) scores including the proportion of immunoreactive cells and their staining intensity were calculated in the basal, suprabasal, superficial as well as the whole epidermal layers of patients and controls. Differential and total IRIDI scores for HSP70 expression showed highly significant higher values in psoriatic patients compared to controls. Statistical differences were found between the different groups of patients; according to their disease severity and controls. Positive correlations also existed between IRIDI scores of patients and disease severity. Based on the findings of the present study, HSP70 is suggested to play a role in the pathogenesis of psoriasis and to correlate with disease severity. Further studies on immunotherapeutic intervention are recommended, aiming at inhibiting events in an ongoing immune response which may provide new therapeutic and perhaps preventive approaches for psoriasis.

ABSTRACT: Water is a vital component to the development of an area. Human settlement is to a large extent dependent on the availability of reliable sources of water preferably in close proximity to the settled localities. This paper examines the hydrochemical facies of groundwater present in the Uyo, Akwa Ibom of Nigeria.  40 Borehole water samples were carefully collected in 8 different locations in Uyo  for various physico – chemical analyses. Calcium, magnesium, iron, zinc, copper, manganese, aluminium, and silver, Nitrate, phosphate, fluoride, chloride, pH, conductivity, total dissolved solid, total suspended solid, hardness, summation of ions as well as the temperature and colour were assessed among the entire samples collected. The results shows that: temperature ranges from 26.3 – 28.3, pH  range is 3.19 – 5.18 . This means the borehole water samples fall within the  highly acidic range. Conductivity ranges between 10.85 and 181.60 μs/cm, TDS range is 4.7 – 86.8mg/l, TSS is between 1.0 and 12.0 mg/l,Total hardness (2.61 – 31.29 mg/l) and Chloride concentration (5.0 – 9.36mg/l). Results show that some of the water samples considered in this work do compare favourably with WHO (1984) water standard for drinking and domestic usages while some other samples of boreholes water fall short of this standard.

Abstract: Garhwal Himalaya has its peculiar topography, vegetation, people and traditions. In the remote areas traditional customs and beliefs are still maintained and modem trends are yet to reach, which provide interesting scope of ethnobotanical studies. The present paper pertains to typical practices in ethnopaediatrics in Garhwal Himalaya, India. The inhabitants use different plants in primary health care of children. Different charms and amulets associated with the common ailments of children have been discussed. [New York Science Journal 2010;3(4):123-126]. (ISSN: 1554-0200).
