BACKGROUND Guaiacol peroxidases (GP) are haem-containing enzymes participating in many physiological processes in plants. The expression pattern of these enzymes is organ-specific and developmentally regulated. METHODS The presence of GP activity in extract samples, prepared from Crocus sativus L. corms that were either dormant or rooting for 3, 6 and 10 days, was investigated. RESULTS Kine...

OBJECTIVE To investigate the effects and potential mechanisms of preconditioning of tricarbonyldichlororuthenium (III) dimer (CORM-2)-liberated CO on LPS-induced activation of endothelial cells (HUVEC). METHODS HUVEC were pretreated with CORM-2 at the concentration of 50 or 100 microM for 2 hrs, washed and stimulated with LPS (10 microg/ml) for additional 4 hrs. Activation (oxidative stress) ...

This paper proposed two acoustic modelings of the onsetrhyme for speech recognition. The two models are Phonotactic Onset-Rhyme Model (PORM) and Contextual Onset-Rhyme Model (CORM). The models comprise a pair of onset and rhyme units, which makes up a syllable. An onset comprises an initial consonant and its transition towards the following vowel. Together with the onset, the rhyme consists of ...

We hypothesized that circulating polymorphonuclear granulocytes (PMNs), vascular endothelial cells (ECs), and perivascular mast cells (MCs) may initiate and sustain the inflammatory response through the generation of the superoxide anion (O(2)(*-)) by PMNs primed by inflammatory stimuli, which in turn evoked the overexpression of adhesion molecules from ECs and release of histamine by MCs. To p...

Carbon monoxide releasing molecules (CORMs) have been suggested as a new synthetic class of antimicrobials to treat bacterial infections. Here we utilized a novel EBOR-CORM-1 ([NEt4][MnBr2(CO)4]) capable of water-triggered CO-release, and tested its efficacy against a collection of clinical Pseudomonas aeruginosa strains that differ in infection-related virulence traits. We found that while EBO...

The present study deals with phytochemical and anthelmintic evaluation of corm of Amorphophallus campanulatus. This evaluation revealed the presence of many phytochemical constituents. Corm was extracted with petroleum ether, chloroform and methanol. Crude tannins were isolated from methanol extract. All extracts and crude tannins were evaluated for anthelmintic activity. Chloroform, methanol e...

Background Besides nitric oxide, carbon monoxide (CO) also activates soluble guanylyl cyclase (sGC). CO as well as the CO-donor CORM-2 have been shown to possess vasodilatory properties. Whether these vasodilatory properties by CO can be attributed to sGC activation is still a matter of debate. The aim of this study was to examine the involvement of sGC and its different subunits in CO and CORM...
