Spectroscopic and electrochemical characterizations of ferrocene- and biferrocene-functionalized terpyridine octanethiolate monolayer-protected clusters were investigated and reported. The electrochemical measurements of Ru2+ coordinated with 4'-ferrocenyl-2,2':6',2' '-terpyridine and 4'-biferrocenyl-2,2':6',2' '-terpyridine complexes were dominated by the Ru2+/Ru3+ redox couple (E(1/2) at appr...

To determine the importance of glucocorticoids in the salt water adaptation of European yellow eel we have evaluated the concentration, affinity and physical properties of glucocorticoid receptors (GR) in gill from both sea water- (SW) and freshwater-adapted (FW) animals. Using ligand binding techniques we demonstrated that high affinity GR were present in both cytosolic and nuclear fractions o...

BACKGROUND Midline destructive lesions of the face (MDL) have a wide range of etiologies. Cutaneous Leishmaniasis (CL) is rarely reported as a possible cause. METHODS Fifteen patients with solitary nasal lesions caused by CL were studied. The clinical data, biopsies/scrapings and PCR were collected/performed. Ridley's Pattern (RP) and Parasitic Index (PI) were documented. RESULTS Patients' ...

Glycosylphosphatidylinositol (GPI) is biosynthesized by the sequential addition of carbohydrates to phosphatidylinositol (PI). In the first two reactions, GlcNAc is transferred from UDP-GlcNAc to PI and then deacetylated to form GlcNAc-PI and GlcN-PI, respectively. In this paper, stimulation of GlcNAc-PI deacetylation by GTP, is reported. Addition of this nucleotide triphosphate to incubations ...

When Brassica nigra leaf petiole suspension cells were subjected to 7 days of inorganic phosphate (Pi) starvation the extractable activity of: (a) pyrophosphate:fructose 6-phosphate 1-phosphotransferase, nonphosphorylating NADP-glyceraldehyde 3-phosphate dehydrogenase, phosphoenolpyruvate phosphatase, and phosphoenolpyruvate carboxylase increased at least fivefold, (b) phosphorylating NAD-glyce...

Six 1-month-old piglets were intravenously injected with deoxynivalenol (DON) at the concentration of 1 mg/kg body weight, with three pigs each necropsied at 6 and 24 h post-injection (PI) for investigation of hepatotoxicity and immunotoxicity with special attention to apoptotic changes and cytokine mRNA expression. Histopathological examination of the DON-injected pigs revealed systemic apopto...

Parent involvement (PI) in school is associated with more positive academic performance and social competence in children. However, there are inadequacies in current measures of PI and a need for a better understanding of predictors of PI. In this study, measures were obtained from a normative sample of 387 children in kindergarten and first grade from high-risk neighborhoods in 4 different sit...

We examined the effect of glucocorticoids on brush border membrane transporters and, furthermore, the involvement of Ca2+ in its action in the primary cultured rabbit renal proximal tubule cells (PTCs). Dexamethasone (DEX, 10(-9) M) decreased Pi uptake by 17%; whereas DEX affected neither alpha-methyl-glucopyranoside (alpha-MG) uptake nor Na+ uptake. The DEX-induced inhibition of Pi uptake was ...
