In this paper,we present a novel,reliable and sensitive electrochemical sensor for the determination of paracetamol based on hollow carbon Co3O4 nanosheets/reduced graphene oxide composite(Co3O4/r-GO).The Co3O4/r-GO was prepared via a rapid one-step microwave solvothermal *** series of techniques that included scanning electron microscopy,X-ray diffraction and Raman were carried out to characterize the morphology and structure of as-prepared *** importantly,the developed electrochemical sensor exhibited a wide linear range of 0.05 to 900.0μM and a low detection limit of 14.0 nM(S/N=3)by using differential pulse ***,the selectivity,repeatability,stability and practical applicability were further studied with satisfactory results.

Laboratory experiments were carried out to investigate the efficacy of crude stem extracts of forest anchomanes, Anchomanes difformis （P. Beauv.） a plant occurring in West African forests, against the pulse beetle Callosobruchus maculattts （Fabricius）. Crude stem extracts at 3% concentration showed high contact toxicity to adult beetles within 24 h after application, while it was moderately toxic to the beetles at the lowest （1%） concentration. At the highest application rate, the plant extract provided good protection to grains stored for 90 days. Grain viability and water absorption capacity were not affected by treatments with ethanol extracts ofA. difformis. The significance of these findings is discussed in relation to biopesticide-means of controlling cowpea bruchids.

Objective To investigate the dose-dependent toxic effect of soybean isoflavone extracts （SIE） on reproductive development in immature rats. Methods Growing male and female rats （n=50 each, 4 weeks） were divided into five groups fed with a standard cereal-based diet and gastrogavaged daily with 0, 30, 150, 300, and 600 mg SIE / kg body weight, respectively, for 12 weeks. Body weight, organ weights, and serum level of estrogen and testosterone were measured. Results Oral administration of SIE had no effect on food intake but decreased food efficiency ratio （P〈0.01）. Suppression on body weight gain by SIE was dose-dependent and the effect was greater on male than on female rats （P〈0.01）. SIE at high doses exhibited hepatotoxicity by increasing a relative liver weight, and also caused a smaller uterus but a greater relative ovary in female rats, while leading to larger relative testis and epididymis in male rats. SIE could decrease progesterone concentrations in female rats, whereas in male rats it reduced not only total testosterone level but also sperm count compared with the control group （P〈0.05）. Conclusion SIE at a range of 50-1000 times of human intake level affects not only growth but also development of reproductive system in growing rats.

Objective To examine the effect of docosahexaenoic acid （DHA） deficiency in brain on spatial learning and memory in rats. Methods Sprague Dawley rats were fed with an n-3 fatty acid deficient diet for two generations to induce DHA depletion in brain, DHA in seven brain regions was analyzed using the gas-liquid chromatography. Morris water maze （MWM） was employed as an assessing index of spatial learning and memory in the n-3 fatty acid deficient adult rats of second generation. Results Feeding an n-3 deficient diet for two generations depleted DHA differently by 39%-63% in the seven brain regions including cerebellum, medulla, hypothalamus, striatum, hippocampus, cortex and midbrain, The MWM test showed that the n-3 deficient rats took a longer time and swam a longer distance to find the escape platform than the n-3 Adq group. Condusion The spatial learning and memory in adult rats are partially impaired by brain DHA depletion.
