Resume We outline in this paper the following view of linguistic meanings. Meanings are planned in the course of speech. The plans, we call them discourse plans (DP), combine referential structure, cognitive situation structure and communicative structure. If and when the DP is realizable, it is transformed into a meaning, which from a technical perspective, is a second order typed lambda term....

The Bacillus subtilis gene senS, when present in high copy number, stimulates the expression of several extracellular protein genes during the onset of stationary phase, e.g. aprE. A novel integration vector, pINT, was constructed for transcription expression studies; it employed a unique method of promoter insert production for fusion with the lacZ reporter gene. Deletions were made of the 5' ...

PURPOSE Immunologic rejection is the most common cause of corneal allograft rejection. Ipsilateral ocular inflammation has been identified as a predictor of future corneal graft failure. This study investigates the effect of perioperative allergic conjunctivitis on corneal allograft survival. METHODS C57BL6 donor corneas were transplanted into naive A/J mice, A/J mice sensitized to short ragw...

Apoptosis in developing Drosophila embryos is rare and confined to specific groups of cells. We explain how one organ, salivary glands, of Drosophila embryos avoids apoptosis. senseless (sens), a Zn-finger transcription factor, is expressed in the salivary primordium and later in the differentiated salivary glands. The regulation of sens expression in the salivary placodes is more complex than ...

l’intérêt de ce bref article consiste à expliciter, dans la mesure du possible, la production et la saisie du sens caché à travers l’étude de la relation des valeurs dans la dimension tensive et sous l’angle sémiotique sensible. nous allons montrer que la perspective de la sémiotique sensible et perceptive fondée sur la phénoménologie peut répondre à toutes les exigences de la compréhension du ...

During sensory organ precursor (SOP) specification, a single cell is selected from a proneural cluster of cells. Here, we present evidence that Senseless (Sens), a zinc-finger transcription factor, plays an important role in this process. We show that Sens is directly activated by proneural proteins in the presumptive SOPs and a few cells surrounding the SOP in most tissues. In the cells that e...

Repeated administration of apomorphine leads to a context-dependent pecking response sens iti zation . Previously sens itized pigeons (Co /llmba /ivia) challenged with saline in the same context show a conditioned response (CR) . The authors studied the effects of intra striatal inj ections of the dopamine (D, ) antagonist SCH-23390 on both the sensiti zed response and the C R. When coadministc...
