Interactions of cationic tetrakis (N,N´,N´´,N´´´-tetramethyltetra-3,4-pyridinoporphyrazinatocobalt(II) (Co(tmtppa)) with synthetic polynucleotides, poly(A-T), poly(G-C) and calf thymus DNA have been characterized in 5 mM phosphate buffer, pH 7.2, by optical absorption and fluorescence spectroscopy. The appearance of hypochromicity effect and the red shift in UV-Vis spectrum of porphyrazine was ...

For a simplicial complex ∆, the graded Betti number βi,j(k[∆]) of the StanleyReisner ring k[∆] over a field k has a combinatorial interpretation due to Hochster. Terai and Hibi showed that if ∆ is the boundary complex of a d-dimensional stacked polytope with n vertices for d ≥ 3, then βk−1,k(k[∆]) = (k − 1) ` n−d k ́ . We prove this combinatorially.

Conduction in inward rectifier, K+-channels in Aplysia neuron and Ba++ blockade of these channels were studied by rapid measurement of the membrane complex admittance in the frequency range 0.05 to 200 Hz during voltage clamps to membrane potentials in the range -90 to -40 mV. Complex ionic conductances of K+ and Cl- rectifiers were extracted from complex admittances of other membrane conductio...

Intranasal route, ensuring suitable bioavailability of medicines under circumvention of the gastrointestinal degradation and hepatic first-pass elimination, has been a popular choice for drug delivery. Among nasal dosage forms, mucoadhesive solid inserts have been shown to resist mucociliary clearance and provide a prolonged nasal residence time. Hence, the purpose of this study was the prepara...

The origin and geodynamic setting of the Maden Complex, which is situated in the Bitlis–Zagros Suture Zone in the Southeast Anatolian Orogenic Belt, is still controversial due to lack of systematic geological and geochemical data. Here we present new whole rock major–trace–rare earth element data from the Middle Eocene volcanic rocks exposed in Maden Complex and discuss their origin in the ligh...
