The syntomic cohomology, more precisely the cohomology of the sheaves s(n) on the syntomic site of a scheme, where introduced in [FM87] in order to prove comparison isomorphisms between crystalline and p-adic étale cohomology. It can be seen as an analogue of the Deligne-Beilinson cohomology in the p-adic world (for an excellent discussion see [Nek98]). In particular, when X is a smooth scheme ...

a b s t r a c t introduction: even today there is no effective drug therapy to prevent neuronal loss after brain stroke. in the present study we studied the effect of mitochondrial katp channel regulators on neuronal ultrastructure after ischemia reperfusion in the rat. materials & methods: rats temporarily subjected to four vessels occlusion for 15 minutes followed by 24 hours reperfusion with...

This study was conducted to evaluate the effects of exogenous polyamines, isopropyl ester, 2, 4-D and naphthalene acetamide application on yield and quality of date palm of ‘Kabkab’ cultivar. The inflorescences sprayed with 2, 4-D isopropylester (0, 10, and 20 mg L-1), naphthalene acetamide (0, 80, and 120 mg L-1), putrescence and spermidine (0, 0.1, and 1.0 mM), three or six weeks after pollin...

The diverse effects of the plant hormone ethylene on development and growth are shaped by the actions of a master regulator of transcription, EIN3.

Research of the molecular events underlying brassinosteroid (BR) signaling is emerging as a new paradigm for studying plant hormone signal transduction pathways. Two recent reports have shown that the BZR1-BES1 family of proteins is a class of novel plant-specific transcription factors that directly bind to and regulate BR-responsive genes, thus filling in key details of the link between hormon...
