Congenital splenic cyst (CSC) is a rare condition, and only a few cases with prenatal diagnosis and no associated malformation have been reported. Spontaneous regression is possible in case of mild CSC (under 40 mm), but enlargement or secondary complications may lead to surgical treatment. We report, herein, two cases of isolated mild CSC with complete spontaneous postnatal regression. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

Summary. Most dung beetles colonize the faeces of several vertebrate species without much discrimination, and are thus often considered as polyphagous. Recent studies have provided evidence for clear feeding preferences in scarab beetles colonizing dung of herbivore species, but little is known about these insects’ abilities to discriminate among odours from faeces of various herbivores. In this study, trophic preferences were examined using blocks of pitfall traps baited with dung from four different herbivore species, i.e., sheep, cattle, horse, and red deer, in a mountainous area of south-central France. 4941 coprophagous scarabs, belonging to 27 species, were captured. Beetles were more attracted to dung of sheep (2257 individuals) than that of cattle (1294 individuals), followed by deer dung (768 individuals) and horse dung (622 individuals). Eleven of the 27 beetle species collected had significant feeding preferences for one of the four dung types. For each insect species, trophic habits did not vary between the two different sites of trapping, an open pasture and a wooded habitat. In laboratory olfactometer bioassays, scarab beetles orientated preferentially towards the dung volatiles from the dung type they preferred in the field. Trypocopris pyrenaeus, Anoplotrupes stercorosus, and Aphodius rufipes were more attracted to volatile compounds from sheep dung, Onthophagus fracticornis significantly preferred horse dung volatiles, and Aphodius haemorrhoidalis responded positively to deer dung odours. The role of dung olfactory cues in the process of resource selection by dung beetles is discussed.  相似文献

Concern for what we do to plants is pivotal for the field of environmental ethics but has scarcely been voiced. This paper examines how plant ethics first emerged from the development of plant science and yet also hit theoretical barriers in that domain. It elaborates on a case study prompted by a legal article on “the dignity of creatures” in the Swiss Constitution. Interestingly, the issue of plant dignity was interpreted as a personification or rather an “animalization of plants.” This sense of irony makes sense when one realizes that on scientific grounds the plant is a “second animal,” i.e., it differs from the animal in degree of life or some ethically-relevant criterion but not in nature. From the point of view of ethics however, plants should be defended for what they are by nature and not by comparison to external references: the ethical standing of plants cannot be indexed to animals. It is thus reckoned that to circumvent this odd fetishism, the plant ethics can only be adequately addressed by changing the theory of plant science. Common sense tells us this: plants and animals belong to radically different fields of perception and experience, a difference that is commonly captured by the notion of kingdom. In this paper we remind the ethical conversation that plants are actually incommensurable with animals because they are unsplit beings (having neither inside nor outside), i.e., they live as “non-topos” in an undivided, unlimited, non-centered state of being. It is concluded that the unique ontology of plants can only be addressed through a major change from object-thinking to process-thinking and a move from ego-centric to “peri-ego” ethics.  相似文献
