Struma ovarii is a monodermal variant of ovarian teratoma, which predominantly contains thyroid tissue. Malignant transformation and metastasis are very rare. The treatment of malignant struma ovarii remains controversial. We report the case of a patient with a recurrent struma ovarii, treated 18 years ago. The malignant transformation and metastases were treated with a combination of surgery and I131 ablation therapy.  相似文献

Located in northern Scandinavia, rock art sites from Alta are the silent witness of ancient people. Considering landscape, surfaces and engravings gives the opportunity to understand the relation of pictures to their context. Simultaneous understanding of both rock surface and picture offer to reach a graphical discourse. On the other hand mythology gives a new perspective to engravings and integrates them into a global values’ system. Power over representation and the rise of sacred feeling produce by those engravings create a special space closer to a higher reality. In that more than natural space respect to precise rules is of the first importance. By a metaphysic's knowledge, the shaman insures good fortune and well-being to the entire group. This paper offers to consider those different aspects and to shed light on their importance.  相似文献

Fossil invertebrates collected or received by Alcide d’Orbigny, all his life long, have been brought together in a renowned collection that is very rich in terms of both species and specimens. The collection has resulted from a huge palaeontological work. Study of faunas from numerous French sites led Alcide d’Orbigny to do biostratigraphical comparisons and to erect geological stages, the definitions of which rest on their stratotypes. His wide knowledge of European fossil faunas was strengthened by a more global palaeobiogeographical view derived from his travel in South America. The d’Orbigny collection is housed in the ‘Muséum’ of Paris and is often visited by experts.  相似文献

À la suite de captures de larves effectuées dans les Monts Bamboutos (Ouest du Cameroun) et de leurs mises en élevage, les auteurs décrivent le mâle, la nymphe et la larve d’Anopheles deemingi Service, 1970 dont seule une femelle était connue. Ils décrivent aussi la nymphe et la femelle d’une nouvelle espèce: Anopheles eouzani n. sp. qui a été capturée dans ces mêmes Monts Bamboutos mais à une altitude supérieure à 2 000 m.  相似文献

Lymphangioma is a benign tumor of the lymphatic system classified as simple, cavernous, or cystic depending on the size of the dilated lymphatic spaces within the tumor. Most cases present as a soft, cystic, slowly enlarging swelling in the neck and axilla in children, while the scrotum is a rare site. We report the case of a 39-year-old man who presented with a painless left hemiscrotal mass. On examination, the testes and spermatic cords were normal bilaterally. There was a firm, polycystic mass in the inferior portion of the left hemiscrotum. Scrotal ultrasound revealed normal testes, with a large complex cystic loculated mass. Histology demonstrated a cystic lymphangioma. The mass was completely excised. The patient remained well without recurrence with a follow-up of 6 months.  相似文献

Despite its small area (20.18 km2), the Eyne Valley, (France, E. Pyrenees) is known to be a place of great faunistic and floristic diversity. The authors have studied the bumblebee fauna of the valley for six years, gathering more than 5000 detailed observations. They observed 33 species, of the 46 living in continental France. For each species, the distribution and ecological preferences (altitude, vegetation type, CORINE biotopes, floral choices) were recorded. Floral resources may be the most important ecological factor. The altitude, the abundance, the diversity of food plants, and the heterogeneity of habitats seem to explain the survival and the coexistence of this great number of species of bumblebees with various ecological affinities.  相似文献

D’Orbigny has created the order of Foraminifera for minute animals classed, at this time, amongst Cephalopoda, and proposed the first classification of this order in 1826, laying the foundations of micropalaeontology. All along his life, he described, figured or clarified diagnosis of about 1500 recent and fossil species. His collections, stored in the National Museum of Natural History in Paris, represent an inestimable patrimony and are still actively consulted. Several micropalaeontologists had contributed to their valorisation and recognised the validity of most of his species. Nowadays, one hundred and two are considered as type species of genera.  相似文献

Making use of those Union Army veterans for whom death certificates are available, we compare the conditions with which they were diagnosed by Civil War pension surgeons to the causes of death on the certificates. We divide the data between those veterans who entered the pension system early because of war injuries and those who entered the pension system after the 1890 reform that made it available to many more veterans. We examine the correlation between specific medical conditions rated by the surgeons and death causes to gauge support for the hypothesis that death is attributable to something specific. We also examine the correlation between the accumulation of rated conditions to the length of time until death to gauge support for the “insult hypothesis.” In general, we find support for both hypotheses. Examining the hazard ratios for dying of a specific condition, there is support for the idea that what ail’d ya’ is what kill’d ya’.  相似文献

Ougandatherium napakense nov. gen. nov. sp., the earliest Rhinocerotidae Iranotheriinae from Africa. The Uganda Palaeontology Expedition discovered an exceptionally rich fossiliferous channel deposit at Napak I, Karamoja, in 1999, which yielded two partial skeletons of a new genus and species of early Miocene Rhinocerotidae, together with various other mammals and gastropods typical of Faunal Set I of East Africa. The age of the deposits on the basis of both faunal correlation (biochronology) and radio-isotopic dating is ca 19–20 Ma. The new genus and species is a hornless rhinoceros about the size of a small horse, with long slender limb bones and metapodials and hypsodont upper cheek teeth whose enamel is undulate, and fossettes cement-filled. Upper premolars possess an inner wall; this is clearly an iranotheriine morphology. As such it is the earliest known African member of this subfamily, close to the oldest member of the subfamily recently discovered at Bugti in Pakistan, a site whose age is about the same.  相似文献

Résumé Certains détersifs appartenant aux groupes anioniques et nonioniques font acquérir auE. coli et auPs. aeruginosa un caractère Gram positif. Seul, le stéarate d[hexaéthylène glycol, détersif nonionique négative la réaction de Gram duM. pyogenes var.aureus. Les modifications du caractère de la réaction de Gram duE. coli, duPs. aeruginosa et duM. pyogenes var.aureus obtenues à l’aide du stéarate d’hexaéthylène glycol sont réversibles en ce sens qu’après un certain temps de contact la bactérie reprend sa réaction primitive. Ainsi donc, pour le staphylocoque, le caractère Gram positif demeure tout d’abord inchangé, puis devient Gram négatif pour reprendre ensuite un caractère Gram positif. Les variations sont en sens inverse pourE. coli etPs. aeruginosa.  相似文献

Résumé Les larves deTrichoplusia ni (Hübner) infectées parVairimorpha (=Nosema) necatrix (Kramer) présentent des sympt?mes chroniques, semi-chroniques et aigus selon les doses de spores deV. necatrix (5 à 500, 5.103 à 5.105 et 5.106 par larve, respectivement) ingérées par larve.V. necatrix parasite principalement le corps adipeux et les tissus des muscles quand les larves ont des sympt?mes chroniques, tandis que les larves manifestent les sympt?mes aigus lorsque les microsporidies attaquent principalement l’intestin moyen. L’histopathologie de la maladie est étudiée.
Summary Infection of larvae ofTrichoplusia ni (Hübner) byVairimorpha, (=Nosema) necatrix was classified as chronic, semi-chronic and acute symptoms depending on the quantity of spores (5 to 500, 5×103 to 5×105, and 5×106 per larva, respectively) ingested per larva.V. necatrix infects mainly the fat body and some muscle tissue of larvae with chronic symptoms and mainly midgut tissue of larvae with acute symptoms.V. necatrix caused death in 3 to 4.5 days when a larva ingested 5×106 spores. The histopathology of the disease was studied.

This paper synthesizes and updates the information coming from the El Sidrón (Asturias, Northern Spain) neandertal site. Since 2000, a new sample of Homo neanderthalensis dated to at least 49,000 years old is being systematically recovered at the El Sidrón cave site. The bone assemblage is located in a secondary position, and certainly derives from a close location. The sample is almost exclusively composed of human remains. There is a moderate number of Middle Paleolithic stone tools (n  415) and very few macro-faunal remains. All skeletal parts are preserved, including some rare bones such as the hyoid bone. Teeth are abundant (n = 213), cranial and postcranial remains are also well represented, but fragmentary, with a special presence of foot and hand bones. A minimum number of thirteen individuals has been identified, comprising different developmental stages from infancy to adulthood: one infant, two juveniles, three adolescents, and seven adults. Paleobiology of the El Sidrón humans fits the pattern found in other neandertal samples: a high incidence of dental hypoplasia and interproximal grooves, yet no serious traumatic lesions are present. Moreover, unambiguous evidence of human-induced modifications (cannibalism) was found on the human remains: cut marks, percussion pitting, conchoidal scars and adhering flakes. Individuals seem to have been treated differentially. Morphologically, the El Sidrón humans show a large number of neandertal lineage-derived features even though certain traits place the sample at the limits of neandertal variation. Integrating the El Sidrón human mandibles and occipital bones into the larger neandertal sample reveals a possible geographic patterning, with southern Neandertals showing broader faces with increased lower facial heights. Ancient DNA analyses have been carried out, developing an anti-contamination protocol of excavation for minimizing the risk of modern human DNA contamination. As a result both mitochondrial and nuclear DNA have been extracted from dental and osteological remains. Curiously, mtDNA comparative analyses suggest a population affinity of Iberian Peninsula Neandertals with Central European Neandertals. Nuclear DNA analyses have permitted the identification of some functional genes such as the melanocortin 1 receptor (MC1R), which regulates hair and skin pigmentation; the FOXP2, a gene involved in the development of language; and the gene involved in the ABO blood group system. Nowadays the large El Sidrón sample is the most significant neandertal sample from the Iberian Peninsula, and augments the European evolutionary lineage fossil record, supporting ecogeographical variability across neandertal populations.  相似文献

Adequate identification of patients for early intervention programmes requires reliable and valid assessment tools. Within the German Schizophrenia Network (Kompetenznetz Schizophrenie) a set of schedules for early detection of schizophrenia has been proposed: the Early Recognition Inventory ERIraos. ERIraos is a two-step procedure with a 17-item checklist used at step 1 by GPs, psychologists, teachers, while a comprehensive 110-item symptom list is applied at early intervention centres at the expert level. In addition, ERIraos allows the assessment of several risk factors for psychosis such as familial load, childhood deficiencies, alcohol and drug use by special modules. Some preliminary results are presented here. The frequency of the 17 checklist symptoms increases from the early to the late prodrome, and more specific symptoms occur over time. The 17 checklist symptoms are grouped by factor analysis to 5 factors (psychotic, depressive, disorganised, withdrawn, dysphoric). In addition to prodromal symptoms, most patients (86.2%) report at least one additional risk factor (mean: 1.7 risks). 68% demonstrate some schizotypal features, 53% report alcohol and/or drug consumption, 24% demonstrate some deficiency or delay in childhood development, 21% report definite obstetric or birth complications, and 10% have a family history of schizophrenia or some schizophrenia-like diagnosis in first degree relatives. So far, the results are of a preliminary nature, and when sufficient information on psychotic transitions is available, the predictive value of ERIraos will be determined.  相似文献

A skeleton of a Channid fish is reported for the first time from the European Lower Miocene. Because of the lack of any appropriate diagnostic character, it is nevertheless impossible to determine if it belongs either to the Asiatic genusChanna Scopoli or to the African one,Parachanna Teugels &Daget. For this reason, its palaeobiogeographical significance remains unclear. Otoliths (sagitta) that very likely belong to the same Channid species have been described from Illerkirchberg asChanna elliptica (vonSalis). They are compared to the sagitta from recent species of the generaChanna (Scopoli) andParachanna (Teugels &Daget). Their morphological characters are intermediate between those characterizing the sagitta of both genera.  相似文献
