The aim of the study was to separate the crude methanol extract of Helianthus annuus into fractions and to evaluate the antidiabetic, antioxidant and preliminary chemical properties of the fractions. The bioassay-guided separation of H. annuus extract was done using column and thin layer chromatographic techniques. The extract yielded thirteen fractions. Bioactivity screening of the fractions (60 mg/kg) using alloxan-induced hyperglycemic rats showed that fraction 8, 9, 10 and 13 caused various degrees of reduction in FBG in time-dependent manner. The activities of the fractions were compared to the crude extract (600 mg/kg). The crude extract (HAE), glibenclamide, fractions 8, 9, 10 and 13 caused 66.74%, 57.43%, 61.36%, 59.80%, 70.63% and 78.03% reductions in FBG, respectively, at 6 h. In vitro anti-oxidant tests at the concentration of 400 µg/ml showed that HAE, fraction 8, 9,10 and 13 gave 89.00%, 30.42%, 47.90%, 88.03% and 92.72% anti-oxidant activity, respectively, using DPPH model and 3.69, 0.95, 0.23, 0.67 and 0.28 µM anti-oxidant potential, respectively, in FRAP model. Ascorbic acid used as control has antioxidant potential of 2.00 µM at concentration of 1000 µg/ml using FRAP model and 99.31% at concentration of 400 µg/ml using DPPH model. Phytochemical spot tests of the HAE showed the presence of saponins, alkaloids, flavonoids, terpenes, glycosides and tannins while fraction 8 and 10 contain mainly saponins, glycosides and sterols and fraction 13 contains mainly tannins.The study validates the use of the preparations from H. annuus leaves in folklore diabetic therapy. © 2015, International Journal of Pharmacognosy and Phytochemical Research.

The collection and management of waste electrical and electronic appliances around the world, and the possible negative environmental consequences have been an issue of current debate. Cathode ray tubes (CRTs) used as display screen for computer monitors and televisions contains large quantities of lead, estimated at between 0.5 and 4 kg, depending on the size of the CRT and has been identified as the most polluting of all electronic waste components. Having failed the tests used in the toxicity characterization of solid wastes, CRTs have been declared 'hazardous' and subsequently banned from landfills and incinerators in most developed countries. Presently, large quantities of CRTs are generated globally with only few developed countries having effective take back and sound management program. Meanwhile, large quantities of CRT-containing devices are being moved across frontiers into developing countries in the name of 'reuse' and 'bridging the digital divide'. With near absence of recycling infrastructure for electronic wastes in most developing countries, waste CRTs are disposed of with MSW at open dumps and unsanitary landfills. This paper reviews the current practices in the management of CRTs around the world, with emphasis on the role of regulations, availability of recycling infrastructure, recycling/reuse routes, and export into developing countries. Inappropriate disposal of waste CRTs creates the opportunity for large-scale environmental contamination with heavy metals, especially lead. Appropriate disposal routes are required globally in the management of CRTs in order to mitigate environmental contamination and human exposure to toxins. © 2010 Elsevier B.V.

Major and trace elements were determined in nzu (calabash clay) from Abia State, Nigeria, by atomic absorption spectrophotometry. Mean calcium content was 1900 ± 100 mg/kg dry weight, followed by Na 1400 ± 96, Fe 1500 ± 480, K 260 ± 150, and Mg 100 ± 48 mg/kg. The mean concentration of Zn was 35 ± 5, Cu 16 ± 2.0, Mn 17 ± 5.0, Cr 10 ± 1.0, Ni 9.0 ± 2.0, Cd 4.3 ± 1.7, Co 3.9 ± 1.1, and Pb 3.0 ± 0.8 mg/kg. The contents of Ba and V were <0.4 mg/kg. The mean Pb content was higher than the WHO safe limit (0.4 mg/kg) and EU (1 mg/kg) limit for food. Estimates of daily intake of Cd, Cr, Fe, and Ni upon consuming 30–80g of nzu were above the recommended daily intake values. The Ba, Ca, Co, K, Mg, Na, and Zn contents should not exceed the recommended daily intake while Cd, Ni, and Pb would pose health risks, especially in pregnancy. The total target hazard quotient indicated potential health risks to consumers. © 2015 Taylor & Francis.

Geohydraulic parameters are essential elements in groundwater resource management and conservation. Most of these parameters especially the hydraulic conductivity and transmissivity are usually estimated from pumping test carried out on drilled boreholes. This paper presents a study conducted in Abi area of the Ikom-Mamfe Embayment with the objective of estimating aquifer parameters from 30 evenly distributed vertical electrical soundings using the Schlumberger configuration and hydrogeologic measurements from 28 boreholes within the area as an alternative way of generating an initial data for groundwater characterisation and quality assessment in the area. The results showed low resistivity ≤45Ωm, hydraulic conductivity ≤2.0×10-5m/s (≤1.7m/day) and transmissivity ≤5.2×10-4m2/s (≤45m2/day) for the water-bearing aquifer horizons in the northeastern and northwestern parts of the study area due to the nature of the aquifer system that were predominantly fractured shale. The sand based aquifers had higher values in the neighbourhood of ~100-800Ωm, ~4.0×10-5-1.0×10-4m/s (~3.46-9.04m/day) and ~6.94×10-4-3.81×10-3m2/s (~60-330m2/day) for the respective parameters mentioned above. The potability of the groundwater system as observed from hydrogeologic measurements of water samples from most boreholes were relatively poor, having electrical conductivity and total dissolved solids values of ~250-931.0μS/cm and ~500-623.77mg/l respectively due to the influence of clay minerals within the aquifer horizon. Some of the vertical electrical sounding points were taken in the vicinity were pumping tests and lithologic data were available for adequate comparison of the results. © 2014 Elsevier Ltd.

The aim of this study was to determine the concentrations of Pb, Cd, Co, and Cr in cosmetic talcum powders regularly used in Nigeria. The samples were mineralized using acids and the trace metal concentrations measured using flame atomic absorption spectrophotometer. Mean concentrations of the trace metals analyzed were 5.0±1.0 mg kg -1 for Pb, 2.1±0.3 mg kg -1 for Cd, 0.7±0.1 mgkg -1 for Co, and 0.2±0.1 mg kg -1 for Cr. Higher metal concentrations compared to others were obtained in few samples manufactured by certain companies, indicating that raw materials used and exogenous contamination could be major contributory factors. The results of this study were generally within regulatory limits. The slightly elevated levels of Pb in few samples indicate that the use of certain talcum powder products could constitute trace metal exposure routes to users. Thus, there is a need for regulation of trace metal levels in cosmetic powders through the establishment of national guidelines. © 2011 Taylor & Francis.

The concentrations of lead and copper in sclerotium of the mushroom Pleurotus tuber-regium widely consumed in Southeastern Nigeria were determined. The specimens purchased from different markets were mineralized with H 2SO 4 and H 2O 2 and analyzed using flame atomic absorption spectrophotometer. The concentrations of Pb ranged from 0.2±0.1 mg kg -1 to 0.8±0.5 mg kg -1 with approximately 91% of the results being below 1mg kg -1. The concentrations of Cu ranged from 0.5±0.2 mg kg -1 to 1.2±0.6 mg kg -1 with 78% of the results below 1mg kg -1. The results were compared with the literature and levels set by regulatory authorities, with the conclusion that the consumption of sclerotium does not pose a toxicological risk. The low Pb content of the studied products would contribute to only about 1% of the provisional tolerable weekly intake of Pb. The Cu contents would contribute to nutritional intake of the metal in the general population. It is recommended that the outer layers of the sclerotia be properly scrapped before use to reduce metal contamination from exogenous sources. © 2011 Taylor & Francis.

Intracranial calcifications underlie certain brain diseases which may be de novo or systemic. But calcifications un-connected to pathologies are classified physiological. To evaluate physiological intracranial calcifications in Douala with establishment of earliest age range of detection. Prospective study of brain computed tomograms was done from April to October 2009 using Schumadzu CT Scan machine. Axial, reconstructed and bone window images as well Hounsfield unit measurements were used for final evaluations. RESULTS were analysed with SSPS 3. 132 patients with 75 males and 57 females were studied and 163 separate calcifications were identified due to co-existent calcifications. The highest calcification was in choroid plexi, constituting 56.82% of the studied population. This was followed by pineal gland. Both were commonly co-existent with advancing age. These calcifications were first seen at 10-19 years. No type of physiological intracranial calcification was seen below age 10. The least calcification of 0.76% of population was in dentate nucleus. No intra-cranial physiological calcifications started earlier than 9 years in Douala, a city in Cameroon, Central Africa.

Background: Low birth weight deliveries are major causes of a huge health burden on poor economies around the globe. It is even more worrisome in developing countries. Materials and Methods: The obstetric records of all low birth weight (LBW) deliveries were reviewed from 1st June 2005 to 30th May 2009. Results: The prevalence of LBW deliveries was 8.3%. Of the LBW babies, 68.4% were preterm, 53.6% were small for gestational age (SGA) and 12.6% were products of multiple gestations. Predominant factors associated with LBW delivery included nulliparity, low parities (1 and 2), parturient aged 25-35 years (80.6%), hypertensive disorders of pregnancy, and short birth spacing (84.4%). Conclusion: Most LBW babies were preterm delivered by low parity parturient aged 25-35 years with short inter-pregnancy intervals. Effective family planning and antenatal services provided particularly for these categories of potential parturient could help to curb the incidence.

The running speed of the North African monitor lizard, Varanus griseus is directly proportional to its body temperature of between 21 and 37°C. Above 37°C, sprint speed does not increase. However, below 21°C, the lizards are extremely sluggish. If pursued at this lowered body temperature the animal finds it difficult to escape and so stays behind and tries to fight the predator. The degree of aggressiveness increases as body temperature is further reduced. This monitor lives in the savanna regions of northern Nigeria where the vegetation is low and hiding places are rare. The lizard might have evolved this antipredatory mechanism at low body temperatures as its last resort to survive since there is no place to take refuge in a bare area when the predator emerges. © 2010 Academic Journals.

Prevalence of adolescent sexual activity is on the increase globally, resulting in increased risk of adverse reproductive health outcomes among them. Sources of sex information are key factors that influence female adolescents' sexual decision-making. Consequently, this study is aimed at identifying adolescents' sources of sexuality information, and its likely effect on their sexual practices among in-school female adolescents in Osisioma LGA, in southeastern Nigeria. A total of 304 girls selected by multi-stage sampling technique were studied. Responses were elicited from them using pretested, semi-structured, self administered questionnaire. Data were analyzed using MS Excel and Epi-6. Primary and subsequent sources of sexuality information were mainly the media and peers. Families and schools mostly were not involved in provision of early sex education. Media and peer influence were predominantly negative. Female adolescents' knowledge of issues of sex was low. Premarital sex, early sexual initiation, and unprotected sex was common among them. Consequently, adverse implication of negative sexual behavior, such as unplanned pregnancies and induced abortion, was prevalent. The study highlights the need for increased roles of parents and teachers in early sexuality education of adolescent girls. This can be done by increasing capacity of parents to discuss sexuality issues with their children. Copyright © 2011 North American Society for Pediatric and Adolescent Gynecology.
