Eukaryotic cells are compartmentalized into membrane-enclosed organelles with defined structure and functions. These organelles are separated from each other, and for a long time it was thought that communication between them is confined to vesicular traffic or to exchange of membrane lipids by cytoplasmic transfer proteins. Recently, however, it has become apparent that organelles hitherto not...

Synovial sarcoma develops as a primary neoplasm of soft tissues, particularly of the extremities, but it has been also reported in a large variety of sites. This tumor is not derived from “synovium”, but from immature mesenchymal elements. Synovial sarcoma accounts for approximately 8-14% of soft tissue sarcomas (1, 2). Although metastases to the lung and/or pleural cavity are common events in ...

In this paper, we propose a notion of colored Motzkin paths and establish a bijection between the n-cell standard Young tableaux (SYT) of bounded height and the colored Motzkin paths of length n. This result not only gives a lattice path interpretation of the standard Young tableaux but also reveals an unexpected intrinsic relation between the set of SYTs with at most 2d+ 1 rows and the set of ...

For example “i” is a YT of shape (4, 3, 1). The YT is said to be standard (an SYT) if the integers in the tableau are 1, 2,..., n as in “. A partition p = (pl, p2 ,..., pt) is strict if p1 > t+ > ... > pt > 0. A generalized Shzyted Young Tableau (abbreviated ST) of shape p is an array of n-integers into t rows with row i containing pi integers and indented i 1 spaces, such that the rows are non...

Alterations in synaptic protein stoichiometry may contribute to neocortical synaptic dysfunction in Alzheimer disease (AD). Whether perturbations in synaptic protein expression occur during the earliest stages of cognitive decline remain unclear. We examined protein levels of synaptophysin (SYP), synaptotagmin (SYT), and drebrin (DRB) in 5 neocortical regions (anterior cingulate, superior front...
