[EUS]Helburuak: Berrikuspen bibliografiko honen helburu orokorra edoskitzea opioideekiko abstinentzia sindrome neonatalaren sintomak arintzeko eraginkorra den aztertzea izango da, eta baita honek tratamendu farmakologikoaren beharra gutxitzen duen. Bestalde, metadona hartzen duten emakume hauen esneko metadona kontzentrazioa nolakoa den eta esne honen bitartez jaioberriari heltzen zaion kantitatea nolakoa den identifikatu nahi da. Metodologia: Artikuluen bilaketa egiteko, datu base desberdinak erabili dira, baina erabilitako azken 8 artikuluak Pubmed eta Ovid-sp-ekoak dira. Artikulu guztiak bat izan ezik, ingelesezkoak dira, gaztelaniaz aurkitutako artikulu kantitate eskasa dela eta. “Edoskitzea” , “abstinentzia sindrome neonatala” eta “metadona terapia" terminoak erabili dira bilaketa prozesuan. Ondorioak: Edoskitzea opioideekiko abstinentzia sindrome neonatala jasaten duten jaioberrientzat gomendagarria dela esan daiteke, ikerketa hauen arabera, abstinentziaren sintomak eta tratamendu farmakologikoaren beharra gutxitzen baititu. Gainera, esneko metadona kontzentrazioa eta jaioberriari honen bitartez heltzen zaion kantitatea oso txikiak dira. Hala ere, lanak limitazioa garrantzitsu bat du, ikerketetako laginak txikiak izatea.

香蕉“威廉斯”品种是华南植物研究所的科技人员1985年以试管苗形成从澳洲引入我国,后来用组织培养技术加速繁殖种苗。1987年开始大田种植,逐步在南方六省市示范推广种植,均表现出丰产且优质性能。到1992年止,种植面积达1.0万公顷,新增产值约4亿元,引种栽培获得了成功,1993年8月广东省科委主持的鉴定会上,专家组意见是:这一结果(引种栽培结果)在国内属首次报导,达到国内领先水平。该品种在我国蕉区种植每公顷产量达30000-45000公斤,比当地蕉产量高30-50%,销售价也高10-15%,种植面积不断扩大,每年新种或改种2000公顷,新增产值近1亿元。

This article considers how Roy Williams's 2003 play, which dramatises a black-on-black killing and the flawed police investigation which follows, represents contemporary British society, particularly in relation to the vexed question of multiculturalism. Some have described "Fallout" as limited and bleak, reinforcing stereotypes of black experience and identity. By contrast, this article demonstrates that the play, through its analysis of both a conflicted police service and the societal divisions that push black youths towards criminality, draws attention to the underlying systemic causes of inner city violence and makes a constructive and valuable contribution to ongoing public debate.

We examine hypotheses for the neural basis of the profile of visual cognition in young children with Williams syndrome (WS). These are: (a) that it is a consequence of anomalies in sensory visual processing; (b) that it is a deficit of the dorsal relative to the ventral cortical stream; (c) that it reflects deficit of frontal function, in particular of fronto-parietal interaction; (d) that it is related to impaired function in the right hemisphere relative to the left. The tests reported here are particularly relevant to (b) and (c). They form part of a more extensive programme of investigating visual, visuospatial, and cognitive function in large group of children with WS children, aged 8 months to 15 years. To compare performance across tests, avoiding floor and ceiling effects, we have measured performance in children with WS in terms of the ‘age equivalence’ for typically developing children. In this paper the relation between dorsal and ventral function was tested by motion and form coherence thresholds respectively. We confirm the presence of a subgroup of children with WS who perform particularly poorly on the motion (dorsal) task. However, such performance is also characteristic of normally developingchildren up to 5 years: thus the WS performance may reflect an overall persisting immaturity of visuospatial processing which is particularly evident in the dorsal stream. Looking at the performance on the global coherence tasks of the entire WS group, we find that there is also a subgroup who have both high form and motion coherence thresholds, relative to the performance of children of the same chronological age and verbal age on the BPVS, suggesting a more general global processing deficit. Frontal function was tested by a counterpointing task, ability to retrieve a ball from a ‘detour box’, and the Stroop-like ‘day-night’ task, all of which require inhibition of a familiar response. When considered in relation to overall development as indexed by vocabulary, the day-night task shows little specific impairment, the detour box shows a significant delay relative to controls, and the counterpointing task shows a marked and persistent deficit in many children. We conclude that frontal control processes show most impairment in WS when they are associated with spatially directed responses, reflecting a deficit of fronto-parietal processing. However, children with WS may successfully reduce the effect of this impairment by verbally mediated strategies. On all these tasks we find a range of difficulties across individual children and a small subset of WS who show very good performance, equivalent to chronological age norms of typically developing children. Neurobiological models of visuo-spatial cognition in children with WS p.4 Overall, we conclude that children with WS have specific processing difficulties with tasks involving frontoparietal circuits within the spatial domain. However, some children with WS can achieve similar performance to typically developing children on some tasks involving the dorsal stream, although the strategies and processing may be different in the two groups.

Williams syndrome is a genetic disorder that, it has been claimed, results in an unusual pattern of linguistic strengths and weaknesses. The current study investigated the hypothesis that there is a reduced influence of lexical knowledge on phonological short-term memory in Williams syndrome. Fourteen children with Williams syndrome and 2 vocabulary la matched control groups, 20 typically developing children and 13 children with learning difficulties, were tested on 2 probed serial-recall tasks. On the basis of previous findings, it was predicted that children with Williams syndrome would demonstrate (a) a reduced effect of lexicality on the recall of list items, (b) relatively poorer recall of list items compared with recall of serial order, and (c) a reduced tendency to produce lexicalization errors in the recall of nonwords. in fact, none of these predictions were supported. Alternative explanations for previous findings and implications for accounts of language development in Williams syndrome are discussed.
