Sexually mature goldfish (Carassius auratus) of both sexes were exposed to two doses (100 and 1000 mug/l) of the widely used herbicide atrazine (2-chloro-4-ethylamino-6-isolropylamino-s-triazine) for a period of 21 days and effects on the concentrations of gonad and plasma sex steroids (testosterone (T), 17beta-estradiol (E2) and 11-ketotestosterone (11-KT)), plasma vitellogenin (VTG) and gonad histo-morphology assessed. Atrazine did not show any obvious estrogenic effect in males, as determined by a lack of vitellogenin induction. There were, however, effects of atrazine on plasma androgen concentrations (androgen dynamics) and tissue (plasma and gonad) estrogen concentrations in male goldfish; exposure to 1000 mug/l atrazine induced suppression in both testosterone and 11-ketotestosterone, and resulted in elevated 17beta-estradiol, after 21 day of exposure. Further, these suppressive effects on plasma androgens and the induction in estrogen were dose- and time-related. The highest atrazine exposure dose induced structural disruption in the testis and both 100 and 1000 mug/l induced elevated levels of atresia in ovaries. (C) 2003 Elsevier B.V. All rights reserved.

In the European Union, the group-housed pregnant sows have to have a minimal legal available area of 2.25m²/sow. However, it has been observed that an increased space allowance reduces agonistic behaviour and consecutive wounds and thus induces better welfare conditions. But, what about the environmental impacts of this greater available area? Therefore, the aim of this study was to quantify pollutant gases emissions (nitrous oxide, N2O, methane, CH4, carbon dioxide, CO2 and ammonia, NH3), according to the space allowance in the raising of gestating sows group-housed on a straw-based deep litter. Four successive batches of 10 gestating sows were each divided into two homogeneous groups and randomly allocated to a treatment: 2.5 v. 3.0m²/sow. The groups were separately kept in two identical rooms. A restricted conventional cereals based diet was provided once a day in individual feeding stalls available only during the feeding time. Rooms were automatically ventilated. The gas emissions were measured by infra red photoacoustic detection during six consecutive days at the 6th, 9th and 12th weeks of gestation. Sows performance (body weight gain, backfat thickness, number and weight of piglets) was not significantly different according to the space allowance. In the room with 3.0m²/sow and compared with the room with 2.5m²/sow, gaseous emissions were significantly greater for NH3 (6.29 v. 5.37 g NH3-N/day per sow; P<0.01) and significantly lower for N2O (1.78 v. 2.48 g N2O-N/day per sow; P<0.01), CH4 (10.15 v. 15.21 g/day per sow; P<0.001), CO2 equivalents (1.11 v. 1.55 kg/day per sow; P<0.001), CO2 (2.12 v. 2.41 kg/day per sow; P,0<001) and H2O (3.10 v. 3.68 kg/day per sow; P<0.001). In conclusion, an increase of the available area for group-housed gestating sow kept on straw-based deep litter seems to be ambiguous on an environmental impacts point of view. Compared with a conventional and legal available area, it favoured NH3 emissions, probably due to an increased emitting surface. However, about greenhouse gases, it decreased N2O, CH4 and CO2 emissions, probably due to reduced anaerobic conditions required for their synthesis, and led to a reduction of CO2 equivalents emissions.

This review gives a survey of the approaches employed to obtain, enhance and tune selectivity in nonaqueous capillary electrophoresis (NACE). Recent developments in NACE are described and the effects of background electrolyte composition and addition of selectors on separation selectivity are discussed. The use of one organic solvent, a mixture of several organic solvents or the use of additives to tune separation selectivity in NACE is presented and a list of relevant applications is included.

The common bean (Phaseolus vulgaris L.) is one of the principal food crops of Rwanda. It is cultivated by 97% of the farms and constitutes the principal source of proteins for the majority of the Rwandan population. One observes since 2000 a considerable reduction in the bean outputs; among the principal causes, one can quote the transmitted diseases and damage caused by insects. In order to contribute to the production of healthy seeds and plant of bean, a test was carried out (February-May 2009) to the station of Rubilizi-ISAE Busogo, from which the objective was to protect the plants of bean against the attacks of insects during the first 8 weeks by coating the seeds with the imidacloprod-gaucho in order to avoid the viral diseases on the plants which result from these seeds and to also thwart the attacks of the principal devastating insects of the bean among which there were the black bean aphid (BBA), Aphis fabae, vector of bean common mosaic virus and the bean stem maggot (BSM), Ophiomyia spp. Three doses of imidacloprid-gaucho were compared to the control, namely 2, 4 and 6g of active matter per kilo of seeds. The results made possible to draw the following conclusions: - the imidacloprid expressed its effects up to eight weeks after sowing; indeed one recorded few close Bean Common Mosaic Virus-attacked plants (less than 3%) until 56 days after sowing; the percentage of virus attacked plant increased beyond to reach 42% for the dose of 2g of imidacloprid per kilo of seeds and only 25% maximum for 4 and 6g of the insecticide product per kilo of seeds; - the imidacloprid allowed also to control the Bean Stem Maggot in the proportion of 58%, 44%, 22% and 18% respectively for the control (0 g), 2, 4, and 6 g of the product per kg of seeds. Within the sight of these results, we can recommend the producers, the pelleting of bean seeds to the dose 4g of imidacloprid-gaucho per kilo of seeds within the framework of the integrated pest management (IPM) against the common mosaic and the damage of Black Bean Aphids and Bean Stem Maggots.

Cadmium (Cd) induces centrilobular emphysema and is suspected to contribute to tobacco related lung diseases as chronic obstructive pulmonary disease (COPD). This study aimed to check whether the inflammatory process observed in rats exposed to nebulised Cd is resistant to betamethasone as observed in COPD and to determine the influence of this drug on airspace enlargement together with the MMP-2-9/TIMP-1-2 imbalance. Our results showed that betamethasone induced emphysema by itself in healthy rats. Moreover, pre-treatment of rats with betamethasone could only partially modulate the increase in bronchoalveolar lavage fluid cell counts and the absence of preventive effect of this compound against emphysema development is associated with its inability to rebalance the MMP-2-9/TIMP-1-2 ratio.
