Cytogenetic and p53 mutation analysis in two cases of severe dysplasia of the bronchial epithelium in lung cancer patients and p53 immunostaining in a third one are reported. The finding of both chromosomal deletions of 17p and p53 mutation indicates that these changes may take place early in the process of lung carcinogenesis. 相似文献

We report the cytogenetic analysis of five cases of follicular thyroid adenoma. In two of them, we observed an identical t(2;3)(q12-13;p24-25) as a unique chromosome change. A third case showed a hyperdiploid karyotype with trisomies of chromosomes 7 and 12. Two cases had a normal diploid karyotype. These changes could define subgroups of follicular adenomas endowed with different malignant potential. 相似文献

A total of 541 cases of cholera were observed between May 7 and July 19, 1985 among the 9,929 displaced persons present in a refugee camp in Africa.In spite of malnutrition and other diseases affecting this population, only 12 deaths occurred.Antiepidemic measures consisted of preparation of isolation-wards, treatment of contaminated materials, training of refugees and patient care. Mass prophylaxis, initially considered, was dropped before the end of the epidemic.Corresponding author. 相似文献

RG, a patient with probable Alzheimer's disease, showed a severe impairment in nonword reading. RG's word reading was intact, for example, as demonstrated by her scores in standardised reading tasks, which were comparable to those of normal controls. No phonological impairment was apparent in speech production and comprehension. Moreover, RG performed well in a series of phonological tasks (e.g., production of a rhyming word, phoneme identification) on which patients with a reading deficit selective for nonwords have been reported to encounter problems. RG's data severely constrain reading models proposing that nonword reading deficits are caused by phonological deficits. However, RG's data are compatible with dual-route reading models, which do not propose a link between nonword reading deficits and phonological impairment. 相似文献

Writing has long been considered to be dependent on speaking. However, modality-specific dissociations between written and spoken word production imply that word production is supported by distinct neural mechanisms in writing, which can be impaired or spared regardless of the intactness of spoken word production. Rapp et al. (2015). Modality and morphology: What we write may not be what we say. Psychological Science, 26, 892–902 documented a double dissociation where problems with regular inflections were selectively restricted to writing or speaking. We report on two English-speaking aphasic individuals who exhibit this same modality-specific dissociation of inflectional processing, replicating the original findings. We expand on Rapp et al.’s study by examining whether the dissociations observed with regular inflections extend to other morphological forms, such as derivation and irregular inflection. Results showed that the dissociation holds for derivation; however, both participants were impaired with irregular inflections in both output modalities. Implications of these findings for morphological processing and the independence of the orthographic system are discussed. 相似文献

Abstract Visual and haptic hallucinations are described in a patient with a right hemisphere infarct. The hallucinations, which lasted intermittently for 10 days, occurred in clear consciousness and in the context of left hemiplegia, sensory loss, hemianopia, and visual neglect. These transient visual hallucinations, characteristic of Charles Bonnet Syndrome, featured children, animals, relatives, dripping water, and traffic, and coexisted with otherwise veridical percepts. Unusual features included the patient's claim to have touched some of the hallucinated objects and the persistent delusion, precipitated by the form of certain hallucinations, that the ward on which she was staying was located one floor above its true position. Specific attention is drawn to the problem of assessing the degree to which the patient showed insight into the hallucinatory nature of some of her percepts. We provide a modular account of the causes of the hallucinations and a central account of how they were interpreted by the patient. 相似文献

A central question for theories of inflected word processing is to determine under what circumstances compositional procedures apply. Some accounts (e.g., the dual-mechanism model; Clahsen, 1999) propose that compositional processes only apply to verbs that take productive affixes. For all other verbs, inflected forms are assumed to be stored in the lexicon in a nondecomposed manner. This account makes clear predictions about the consequences of disruption to the lexical access mechanisms involved in the spoken production of inflected forms. Briefly, it predicts that nonproductive forms (which require lexical access) should be more affected than productive forms (which, depending on the language task, may not). We tested these predictions through the detailed analysis of the spoken production of a German-speaking individual with an acquired lexical impairment resulting from a stroke. Analyses of response accuracy, error types, and frequency effects revealed that combinatorial processes are not restricted to verbs that take productive inflections. On this basis, we propose an alternative account, the stem-based assembly model (SAM), which posits that combinatorial processes may be available to all stems and not only to those that combine with productive affixes. 相似文献

Approximately 5% of the population in Western countries is affected by autoimmune diseases (AID), with a significantly higher prevalence in women. Genetic factors are known to be crucial determinants of susceptibility as shown by family and twin studies, although no specific genes predisposing women to autoimmunity have been identified thus far. Several studies indicate that X chromosome abnormalities, such as inactivation patterns, characterize some female-predominant AID. We herein review the most recent evidence on the role of the X chromosome in the breakdown of immune tolerance and discuss its potential implications. Future efforts will help to identify specific X chromosome regions containing candidate genes for disease susceptibility. 相似文献

Recent studies reported enhanced performance on language tasks induced by transcranial direct current stimulation (tDCS) in patients with aphasia. One chronic patient with non-fluent aphasia received 20 sessions of a verb anomia training combined with off-line bihemispheric tDCS applied to the dorsolateral prefrontal cortex (DLPFC) – anodal tDCS over left DLPFC plus cathodal tDCS over right DLPFC. A significant improvement in verb naming was observed at all testing times (4, 12, 24, and 48 weeks from post-entry/baseline testing) for treated and untreated verbs. Our findings show beneficial effects of verb anomia training in combination with tDCS in chronic aphasic patient, suggesting a long-lasting effect of this treatment. 相似文献

We describe the case of a young woman showing yolk sac tumors (YST) and a Sertoli-Leydig cell tumor (SLCT) in the right ovary, with recurrences in the right adnexum and with hepatic metastasis. To our knowledge, YST and SLCT have never been described as components of the same tumor or reported as associated in the same patient. The patient's karyotype showed the presence of Y chromosome inserted into the 1qh region; the inserted region corresponded to Yq12 heterochromatin. LOH analysis revealed 1p36 paternal allele loss in the proband tumor, thus supporting a germ cell origin for the tumor. The presence of Y heterochromatin in 1qh DNA might induce disturbances in the normal regulation of oncogenes located in 1q. 相似文献
