short-term visual retrieving processes were investigated in three groups, of schizophernics (n=10), right hemisphere brain damaged (n=10) and a normal grou (n=10) . all of subjects were men and right handed. the study utilized wais (verbal subtests), meaningless syllabuses, retrieve and recall tests and non-verbal patternes retrieve and recall tests. data were analyzed by three factor repeated ...

Brain functions are strictly dependent on neural connections formed during development and modified during life. The cellular and molecular mechanisms underlying synaptogenesis and plastic changes involved in learning and memory have been analyzed in detail in simple animals such as invertebrates and in circuits of mammalian brains mainly by intracellular recordings of neuronal activity. In the...

DNA microarrays are widely used as end point detectors for gene expression analysis. Several methods have been developed for target labelling to enable quantification but without taking target length into consideration. Here we highlight the importance of choosing the optimum target length that would ensure specificity without compromising sensitivity of the assay. For this, eight plasmids that...

We investigate the problem of designing efficient multiplex PCR for medical applications. We show that the problem is NP-complete by transformation to the Multiple Choice Matching problem and give an efficient approximation algorithm. We developed this algorithm in a computer program that predicts which genomic regions may be simultaneously amplified by PCR. Practical use of the software shows ...
