Evaluation of wound healing active principles in the transdermal patch formulated with crude bio wastes and plant extracts against GSK-3 beta an study.

The wound-healing process is accelerated by inhibiting proteins that decelerate the wound-healing pathway. One of the active proteins involved in enhancing healing at the nuclear level and in gene expression is catenin. Inhibition of Glycogen Synthase Kinase 3β (GSK3 β) phosphorylates and degrades catenin via the downstream Wnt signalling pathway, thereby stabilizing catenin.

Efficacy of metformin in human single hair fibre by ATR-FTIR spectroscopy coupled with statistical analysis.

Diabetes mellitus is chronic metabolic disorder, resulting from insulin deficiency, characterized by hyperglycemia altered metabolism of carbohydrates, proteins and lipids and an increased risk of vascular complications. There are different classes of anti-diabetic drugs in allopathic system of medicine. Metformin (dimethyl biguanide) is a blood glucose lowering agent used in the treatment of non-insulin dependent diabetes mellitus.

Vibrational analysis, electronic structure and nonlinear optical properties of levofloxacin by density functional theory.

The Fourier transform (FT-IR) spectrum of Levofloxacin was recorded in the region 4000-400 cm(-1) and a complete vibrational assignment of fundamental vibrational modes of the molecule was carried out using density functional method. The observed fundamental modes have been compared with the harmonic vibrational frequencies computed using DFT (B3LYP) method by employing 6-31 G (d, p) basis sets. The most stable geometry of the molecule under investigation has been determined from the potential energy scan.

Theoretical and experimental studies of vibrational spectra and thermodynamical analysis of 3'-bromopropiophenone and 4'-bromo-3-chloropropiophenone.

Quantum chemical calculations of molecular geometries, vibrational wavenumbers and thermodynamical properties of 3'-bromopropiophenone and 4'-bromo-3-chloropropiophenone were carried out using Hartree-Fock (HF) and density functional theory (DFT) using hybrid functional B3LYP with 6-31 G (d,p) as basis set. The optimized geometrical parameters obtained by HF and DFT calculations are in good agreement with the experimental FTIR and FT Raman spectral datas. The observed and the calculated frequencies are found to be in good agreement.

Theoretical and experimental studies of vibrational spectra and thermal analysis of 2-nitroaniline and its cation.

The FTIR spectrum of 2-nitroaniline was recorded in the regions 4000-400 cm(-1). The optimized molecular geometry, bond orders, atomic charges, harmonic vibrational wave numbers and intensities of vibrational bands of 2-nitroaniline and its cation were calculated at DFT levels invoking two different basis sets 6-31G and 6-31+G using Gaussian 03W program. The X-ray geometry and FTIR vibrational frequencies were compared with the results of DFT calculations.

Vibrational spectral assignments of paraldehyde by ab initio and density functional methods.

The FTIR and Laser-Raman spectra of paraldehyde have been recorded in the regions 4000-400 cm(-1) and 3500-250 cm(-1) respectively. Molecular electronic energy, geometrical structure, harmonic vibrational spectra, infrared intensities and Raman scattering activities have been computed at the HF/6-31G(d,p) and B3LYP/6-31G(d,p) levels of theory. The results were compared with experimental values with the help of scaling procedures.
