We investigated the time course of the amplitude specification of rapid bimanual reversal movements (lateral displacements
on two digitizers). To this end we used the timed-response paradigm in which the response has to be initiated synchronously
with an auditory signal. Information about the required amplitudes was presented at various times before the synchronization
signal. Consistent with previous results, the progression of amplitude specification was reflected in the dependence of the
amplitudes of the reversal movements on the time interval between amplitude information and synchronization signal. Same or
different amplitudes for the hands were used to examine cross-talk at the programming level of the two-level model of intermanual
interference. The results indicate the existence of cross-talk in particular at short intervals between information about
amplitude and movement initiation. This is consistent with the notion that cross-talk between concurrent processes of amplitude
specification is transient and vanishes as the time available for motor programming increases.

BackgroundParkinson’s Disease patients undergo time-consuming programming to refine stimulation parameters after deep brain stimulation surgery.ObjectiveTo assess whether the use of the advanced functions of a patient’s programmer would facilitate programming of deep brain stimulation.MethodsThirty patients were randomly allocated to the use of advanced versus simple mode of the patient programmer in this single-centre, prospective, randomized, controlled study. Primary outcome was the number of days required to optimize the stimulation settings.ResultsThe number of days required to optimize stimulation was significantly lower in the simple mode (88.5 ± 33.1 vs. 142.1 ± 67.4, p = 0.01). In addition, the advanced mode group had a higher number of side effects (5.4 ± 3.1 vs. 2.6 ± 1.9, p = 0.0055).ConclusionsThe use of the advanced functions of patient programmer delays programming optimization and it is associated with a higher number of side effects. These findings highlight the need for other methods for faster and safer stimulation programming. 相似文献

Objectives - To investigate whether impaired fetal growth, measured by low birth weight and short birth length, is linked with raised levels of serum lipids and increased risk and mortality of coronary heart disease. Design - The association between birth length, birth weight, Ponderal Index and total serum cholesterol was examined in 545 Danish men and women aged 31 to 51 years who participated in the Ebeltoft Health Promotion Project in Denmark. Results - No associations were found in women. For men, a negative association was found between birth weight and serum total cholesterol, with a fall in mean serum total cholesterol from 6.03 mmol/l at birth weight below 3300 g to 5.64 mmol/l at birth weight above 4000. A similar association was found between birth length and serum cholesterol, with a mean value of 6.23 mmol/l at birth length below 51 cm and a mean value of 5.56 mmol/l at birth length above 54 cm. No associations were found for Ponderal Index. Between 3% and 8% of the variance in serum total cholesterol could be explained by the statistical models used in this study. Conclusion - Our findings support the hypothesis of a negative association between birth weight, birth length and elevated serum cholesterol in adult life, but only in men. 相似文献

The fetal, neonatal, and infant environments-the long-term consequences for disease risk 总被引:2,自引:0,他引:2
The developmental origins of health and disease can be understood by reference to the fundamentals of developmental plasticity. It is essential to distinguish between those environmental effects acting during development that are disruptive from those that have adaptive value. The latter are likely to underpin programming and the developmental origins of adult disease. It is suggested that greater disease risk is created by a mismatch between the environment predicted during the plastic phase of development and the actual environment experienced in the postplastic phase. This plastic phase extends from conception to after birth at least for some systems. It is not necessary to invoke a particular mechanism in the neonatal or infant period. There is increasing evidence that prematurity can be associated with long-term consequences, and this is to be anticipated from conceptual considerations. Different preventative strategies may be relevant in different populations. 相似文献

OBJECTIVE: To determine effects of maternal or fetal injections of betamethasone on postnatal growth and arterial pressure. STUDY DESIGN: We measured body weight, arterial pressure, and heart rate serially in sheep born after single or repeated maternal or fetal betamethasone injections. At approximately 3.5 years, organ weights were measured. RESULTS: Repeated maternal betamethasone injections caused intrauterine growth restriction, and low body weight and blood pressure at 3 months. From 6 months to 3 years, body weight, blood pressure, and heart rate were not affected by treatment. At approximately 3.5 years, brain weight was reduced after single or repeated maternal betamethasone by 13% and 18%, respectively (P = .001). Fetal betamethasone reduced brain weight by 7% to 8% (P = .018). Weights of other organs were not affected by treatment. Brain weight was unrelated to body weight at approximately 3.5 years (P = .649) but was related to birth weight (P = .029). CONCLUSION: Prenatal betamethasone does not have long-term effects on blood pressure but causes a persistent deficit in brain weight. 相似文献
