Ontogeny of arousal data constitute a vital supplement to the sparse literature on spontaneous neuronal activity. These data demonstrate that measurable infant spontaneous arousals (SAs) with an inherent oscillatory entrainment occur six times more in active sleep than in quiet sleep of the same duration and are identifiable as a human neurobiologic function. These SAs are not significantly associated with race or ethnicity, gender, total hours spent sleeping, percent time spent in active or quiet sleep, preterm status, history of a life-threatening event, having had a sibling who died of sudden infant death syndrome (SIDS), or having had a mother who smoked during this pregnancy. As measurable neurophysiologic events, SAs establish parameters for research at molecular and molar levels focusing on several critical areas: (1) the neuronal control of SA related to neurotransmitters, (2) as a significant antecedent factor in clinical cardiorespiratory events occurring in infants at high epidemiologic risk for SIDS; (3) as a regulatory biologic factor underlying temperament and executive cognitive functioning, and (4) morbidity and mortality effects possibly related to therapeutic interventions that alter SA levels. 相似文献

Utrophin: A Structural and Functional Comparison to Dystrophin 总被引:9,自引:0,他引:9
Derek J. Blake Jonathon M. Tinsley Kay E. Davies 《Brain pathology (Zurich, Switzerland)》1996,6(1):37-47
Utrophin is an autosomally-encoded homologue of dystrophin, the protein product of the Duchenne muscular dystrophy (DMD) gene. Although, Utrophin is very similar in sequence to dystrophin and possesses many of the protein-binding properties ascribed to dystrophin, both proteins are expressed in an apparently reciprocal manner and may be coordinately regulated. In normal skeletal muscle, Utrophin is found at the neuromuscular junction (NMJ) whereas dystrophin predominates at the sarcolemma. However, during development, and in some myopathies including DMD, utrophin is also found at the sarcolemma. This re-distribution is often associated with a significant increase in the levels of utrophin. At the NMJ utrophin co-localizes with the acetylcholine receptors (AChR) and may play a role in the stabilization of the synaptic cytoskeleton. Because utrophin and dystrophin are so similar, utrophin may be able to replace dystrophin in dystrophin deficient muscle. This review compares the structure and function of utrophin to dystrophin and discusses the rationale behind the use of utrophin as a potential therapeutic agent. 相似文献

Precipitating antibodies to an insect pathogenic RNA virus of Darna trima from East Malaysia have been found in a small percentage of human sera from several different groups of persons in West Malaysia and the United Kingdom. No associated illness was identified. The results suggest that an antigenically related virus or viruses are present in the environment that may be associated with symptomless or inapparent infections in man. 相似文献
