Traditional strategies of resource use in lowland coastal areas may play a very significant role in modern environmental management since, in many ways, the cultural and biological diversity peculiar to these ecoystems that we now wish to protect are the product of human efforts rather than the product of nature alone. We will illustrate this using the example of the so-called closes (enclosures) in the Natural Park of the Aiguamolls de l'Emporda (Catalonia, Spain). Closes are pasture fields surrounded by tree screens that remain inundated part of the year but that can be used for cattle grazing during the rest of the time. Because of agricultural modernization in the 1960s and 1970s many closes were turned into permanent agricultural fields. Since the creation of the Natural Park in 1983, there has been an attempt to recover these traditional land uses although not without some opposition by the farming sector. 相似文献

Genetically modified (GM) crops have been recognised to be economically beneficial to subsistence farmers and have been projected
as essential tools for addressing challenges in hunger, environmental sustainability and international development. Yet the
uncertainty of their effects on human health and the undesirable ecological consequences of these organisms have raised concerns
on the rapid pace of their production. Regulating the release of these organisms is a critical environmental issue. The Cartagena
protocol on bio-safety, the principle legal arrangement for the regulation of these organisms, has ratifications from only
157 countries and has proven to be a weak regulator. Countries like India and Brazil have seen the proliferation of unapproved
stealth GM varieties which make regulation even more difficult. In this paper, we explore the debate surrounding the introduction
of GM organisms and analyse the effectiveness of existing legal regimes to regulate their use. 相似文献

Polychlorinated biphenyls (PCBs) are toxic environmental contaminants, which tend to accumulate in the food chain. Since dietary intake is the most important exposure route, PCB body burden may be affected by taking proper dietary measures. In the present study, diets were supplemented with either wheat bran or its cellulose based placebo in order to study the effect of bran consumption on the absorption of dietary PCBs and the excretion of initially stored PCBs. During the period of PCB intake, faecal PCB excretion was elevated by consumption of wheat bran as compared to the placebo. Hence, apparent faecal PCB digestibilities as well as PCB retentions in the whole body were lower in the wheat bran consuming rats. After ending PCB consumption, dietary wheat bran had only a minor effect on faecal PCB output while accumulation in the body was not affected. When PCBs were consumed for a longer time, a small but significant reduction of apparent faecal PCB digestibility was found. However, PCB content in the body kept increasing while PCB retention as percent of intake remained almost constant. Furthermore, differences among individual PCB congeners in metabolic susceptibility and hydrophobic characteristics had an impact on their accumulation in the body. 相似文献

A rare case of extrahepatic biliary atresia was diagnosed by a combination of prenatal ultrasound and measurements of fetal digestive enzymes in amniotic fluid. Ultrasound at 15 and 18 weeks' gestation failed to detect the gall bladder, and amniotic fluid digestive enzyme values were below the fifth percentile. The patient decided to terminate the pregnancy. Post-abortal pathological examination confirmed the diagnosis. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

The median maternal serum free beta human chorionic gonadotropin (hCG) multiple of the median (MOM) of 480 Down syndrome cases in the second trimester was 2·64, significantly greater than the reported median MOM of intact hCG (p<0·0001). In 234 of these cases from retrospective and prospective studies, the effectiveness of maternal serum free beta hCG was evaluated in combination with alpha-fetoprotein (AFP) and maternal age in second-trimester Down syndrome screening. Down syndrome detection in the gestational age range of 14–16 weeks was 82 per cent. In all gestational weeks (14–22), a 77·7 per cent Down syndrome detection rate was achieved. In prospective screening of 44 272 patients under the age of 35 years, 69 per cent of Down syndrome cases were detected (73 per cent in gestational weeks 14–16). The false-positive rate for the prospective study was 3·8 per cent. The use of free beta hCG combined with maternal serum AFP and maternal age-related risk for Down syndrome in a screening population (i.e., women under 35 years) yields an improved detection efficiency over other protocols. 相似文献
