let r and s be reduced rings with identities whose idempotents are central, and let m be an(r, s)-bimodule such that annr (m)=0. in this paper, we determine first the structure of automorphisms ofthe triangular ring, =sr mt0, and then, for all automorphisms α ,β of t we determine the structureof (α,β)-derivations of t.

background: the present study investigated the functional maturity of oligodendrocyte derived from rat bone marrow stromal cells (bmsc). methods: the bmsc were isolated from female sprague-dawley rats and evaluated for different markers, such as fibronectin, cd106, cd90, oct-4 and cd45. transdifferentiation of olc from bmsc was obtained by exposing the bmsc to dmso and 1 µm all-trans-retinoic a...

objective: stevioside is a natural non-caloric sweetener which has been reported to have anti-inflammatory activity.  the aim of  the present study was to examine in vitro and in vivo effects of  stevioside on rats  plasma levels of tumor necrosis factor- α (tnf-α),  interleukin-1β (il-1β), tnf-α and il-1β release from lipopolysaccharide(lps)-stimulated rat peripheral blood mononuclear cells (p...

estrogen (e2) has neuroprotective effects on blood-brain-barrier (bbb) after traumatic brain injury (tbi). in order to investigate the roles of estrogen receptors (ers) in these kind of effects, er-α antagonist (mpp) and, er-β antagonist (phtpp), or non-selective estrogen receptors antagonist (ici 182780) were administered as regulators of cns cytokines levels and neuroinflammation after tbi. m...

objective(s): the present study was aimed to investigate the influence of thoracic epidural blockade on hypoxia-induced pulmonary hypertension in rats. materials and methods: forty eight wistar rats were randomly divided into 4 equal groups, named normoxia hypoxia hypoxia/ ropivacaine and hypoxia/saline. animals were placed in a hypoxia chamber and instrumented with epidural catheters at the th...
