We present a new proof of Stembridge’s theorem about the enumeration of totally symmetric plane partitions using the methodology suggested in the recent Koutschan-Kauers-Zeilberger semi-rigorous proof of the Andrews-Robbins q-TSPP conjecture. Our proof makes heavy use of computer algebra and is completely automatic. We describe new methods that make the computations feasible in the first place....
The activation parameters and the rate constants of the water-exchange reactions of Mn(III)TE-2-PyP(5+) (meso-tetrakis(N-ethylpyridinium-2-yl)porphyrin) as cationic, Mn(III)TnHex-2-PyP(5+) (meso-tetrakis(N-n-hexylpyridinium-2-yl)porphyrin) as sterically shielded cationic, and Mn(III)TSPP(3-) (meso-tetrakis(4-sulfonatophenyl)porphyrin) as anionic manganese(iii) porphyrins were determined from th...
Mechanical and structural properties of ionically self-assembled nanostructures of meso-tetra(4-sulfonatophenyl)porphyrin (TSPP) and meso-tetra(4-pyridyl)porphyrin (TPyP) are presented. This is the first time that elastic modulus of an ionic porphyrin nanostructure has been reported. X-ray photoelectron spectroscopy (XPS), UV-visible spectra, and elemental analysis all support a stoichiometric ...
Cu is thought to play an important role in the pathogenesis of several neurodegenerative diseases, such as Wilson's, Alzheimer's, and probably in prion protein diseases like Creutzfeld-Jakob's disease. Until now, no method existed to determine the concentration of this cation in vivo. Here, we present two possible approaches combined with a critical comparison of the results. The successful use...
Aerobic oxidative N-dealkylation of a variety of aliphatic tertiary amines and anilines catalyzed by rhodium(III) tetra (p-sulfonatophenyl) porphyrin ((TSPP)Rh(III)) is achieved in aqueous solution using dioxygen as the sole oxidant.
A novel approach to chemical application of long period grating (LPG) optical fibers was demonstrated, which were modified with a film nanoassembled by the alternate deposition of SiO(2) nanoparticles (SiO(2) NPs) and poly(diallyldimethyl ammonium chloride) (PDDA). Nanopores of the sensor film could be used for sensitive adsorption of chemical species in water, which induced the changes in the ...
Inflammatory status affects the antitumor activity of poly-epitope-peptide vaccination against the thymidylate synthase in metastatic colo-rectal cancer patients enrolled in TSPP/VAC-1 Phase Ib trial Pierpaolo Correale, Valerio Nardone, Cirino Botta, Elodia Martino, Pierpaolo Pastina, Cristina Ulivieri, Maria Grazia Rossetti, Antonella Fioravanti, Claudia Gandolfo, Francesco Carbone, Tatiana Co...
Selective oxidation of alcohol in water using molecular oxygen as the terminal oxidant is mediated by rhodium porphyrin complexes. Addition of methanol to an aqueous solution of (TSPP)Rh(III) resulted in observation of the key intermediate porphyrin rhodium(III) methoxide species. The activation parameters for betaC-H elimination of Rh-alkoxide were evaluated.
