On the nature of the unusually long OO bond in HO(3) and HO(4) radicals.
The HO(3) and HO(4) polyoxide radicals have attracted some attention due to their potential role in ozone chemistry. Experimentally, the geometrical structure of HO(3) is known whereas that of HO(4) is not. Moreover, the existence of the latter radical has been questioned. Theoretical calculations on the two species have been reported before, showing important structural differences depending o...
متن کاملHeme: a novel inducer of MCP-1 through HO-dependent and HO-independent mechanisms.
This study examined the effect of hemin on the expression of heme oxygenase-1 (HO-1) and monocyte chemoattractant protein-1 (MCP-1) in immortalized rat proximal tubular epithelial cells (IRPTCs). Hemin elicited a dose- and time-dependent induction of HO-1 and MCP-1 mRNA. HO activity contributed to MCP-1 mRNA expression at early time points (4-6 h) because inhibition of HO activity by zinc proto...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولHO-1 inhibits migration of leukemic cells
The complement cascade (ComC) is a crucial element of innate immunity and is involved in several processes related to fighting infection by releasing active mediators, including C3a and desArgC3a, which result from cleavage of complement component 3 (C3), and C5a and desArgC5a, which result from cleavage of complement component 5 (C5) [1-3]. In parallel, evidence has accumulated that, in additi...
متن کاملHeme oxygenase 1 (HO-1) regulates osteoclastogenesis and bone resorption.
Heme oxygenase 1 (HO-1) plays an important role in vascular disease, transplantation, and inflammation. In animal models of acute and chronic inflammation, induction of HO-1 has anti-inflammatory and cytoprotective properties. Since inflammation is an important trigger of osteoclastogenesis, we hypothesized that HO-1 might influence osteoclastogenesis. We investigated the effects of induction o...
