Gene regulatory networks inferred from RNA abundance data have generated significant interest, but despite this, gene network approaches are used infrequently and often require input from bioinformaticians. We have assembled a suite of tools for analysing regulatory networks, and we illustrate their use with microarray datasets generated in human(More)
Some drugs affect secretion of secreted proteins (e.g. cytokines) released from target cells, but it remains unclear whether these proteins act in an autocrine manner and directly effect the cells on which the drugs act. In this study, we propose a computational method for testing a biological hypothesis: there exist autocrine signaling pathways that are(More)
This study investigated the developmental age at which infants recognize about supporting relations between objects and what information they use to judge whether a supported object will fall down or not. Four kinds of events were used. All events involved support in relation of two boxes, which differed in the amount of contact between objects and the(More)
A cross-cultural study was conducted to examine the extent to which certain environment-child development relationships can be generalized across two cultures. Participants were 103 trainable mentally retarded (TMR) children and their families in Japan and 88 TMR children and their families in the United States. The relation between cognitive stimulation(More)
