  • Experimental and theoretical studies of vibrational spectrum and molecular structure and related properties of pyridoxine (vitamin B6).

Electronic address: rayadav@bhu.ac.in.AbstractVibrational spectrum of pyridoxine has been investigated using experimental IR and Raman spectroscopic and density functional theory (DFT) methods. Vibrational assignments of the observed IR and Raman bands have been proposed in light of the results obtained from computations. In order to assign the observed IR and Raman frequencies the potential energy distributions (PEDs) have also been computed. Optimized geometrical parameters suggest that if the OH groups of the two methyl groups are replaced by H atoms the resulting molecule has Cs point group symmetry. To investigate molecular stability and bond strength we have used natural bond orbital analysis (NBO). Charge transfer occurs in the molecule have been shown by the calculated highest occupied molecular orbital-lowest unoccupied molecular orbital (HOMO-LUMO) energies. The mapping of electron density iso-surface with electrostatic potential (ESP), has been carried out to get the information about the size, shape, charge density distribution and site of chemical reactivity of the molecule.

Electronic address: zelko.romana@pharma.semmelweis-univ.hu.AbstractSolvent cast and freeze dried films, containing the water-soluble vitamin B12 as model drug were prepared from two polymers, sodium alginate (SA), and Carbopol 71G (CP). The proportion of the CP was changed in the films. The microstructural characterization of various samples was carried out by positron annihilation lifetime spectroscopy (PALS). The drug release kinetics of untreated and stored samples was evaluated by the conventionally applied semi-empirical power law. Correlation was found between the changes of the characteristic parameters of the drug release and the ortho-positronium (o-Ps) lifetime values of polymer samples. The results indicated that the increase of CP concentration, the freeze-drying process and the storage at 75% R.H. decreased the rate of drug release. The PALS method enabled the distinction between the micro- and macrostructural factors influencing the drug release profile of polymer films.

  • Radiofrequency ablation suppresses distant tumour growth in a novel rat model of multifocal hepatocellular carcinoma.
  • Erös de Bethlenfalva-Hora C, Mertens JC, Piguet AC, Kettenbach J, Schmitt J, Terracciano L, Weimann R, Dufour JF, Geier A.Author information *Hepatology, Department of Clinical Research, University of Bern, Bern, Switzerland.AbstractRFA (radiofrequency ablation) is an established therapy for HCC (hepatocellular carcinoma). The multikinase inhibitor sorafenib prolongs survival in advanced HCC. We examined the effects of RFA alone and in combination with sorafenib on a bystanding tumour in a two-tumour rat model of HCC. A total of 80 rats were implanted with two liver tumours and randomized to four treatment groups: vehicle and sham operation (control), sorafenib and sham operation (Sora/Sham), vehicle and RFA (Vh/RFA), and sorafenib and RFA (Sora/RFA) (n=10/group per time point). RFA or sham-operation was performed on the left lobe tumour on day 15. Animals were killed at day 18 and day 30. Non-RFA-targeted right lobe tumours were analysed for angiogenesis, growth factors [HGF (hepatocyte growth factor), EGF (epidermal growth factor) and VEGF (vascular endothelial growth factor)] and infiltrating immune cells (CD3 and CD68). At day 30, the non-RFA-targeted tumours were significantly smaller in all three treatment groups compared with control (Sora/Sham P≤0.0001, Vh/RFA P=0.005 and Sora/RFA P≤0.0001). The smallest tumours were observed in animals treated with a combination of sorafenib and RFA, whereas the size reduction seen in the RFA-only group indicated an RFA-mediated distant suppression of tumour growth. Growth factor measurement revealed transiently decreased EGF levels after RFA (P=0.008), whereas sorafenib treatment decreased HGF levels (P=0.001). MVD (microvessel density) was reduced by sorafenib (P=0.002) despite increased VEGF levels (P≤0.0001). The immune parameters revealed augmented T-cells and IL-10 (interleukin 10) levels in all three treatment groups; sorafenib additionally increased macrophage numbers (P≤0.0001). RFA and sorafenib alone resulted in significant volume reduction of the non-RFA-targeted tumour; this effect was enhanced when both modalities were combined.
