Figure 2 Using the indices of haemoglobin (IHb) colour chart function provided by the Olympus EVIS LUCERA system, the reference IHb values are displayed in yellow, with areas higher than the reference value (hypervascular) displayed in “warm” colours (i. e., orange±red) and hypoperfused areas displayed in “cool” col− ours (blue±grey). IHb charting of the lesion shows a clear vascular map. The l...

Quinine is an alkaloid with powerful antimalarial activity, isolated from the bark of Peru's cinchona trees. Quinidine is an erythro diastereoisomer of quinine also exhibiting antimalarial activity. Conformational studies performed so far had never identified conformers with intramolecular hydrogen bonds (IHB). The current study shows the possibility of conformers with an IHB between the quinuc...

In January of 1979, a railroad tank car containing the chemical acrylonitrile started leaking at a rail yard in south suburban Chicago. The chemical was manufactured by American Cyanamid Co (Cyanamid) in Louisiana. Cyanamid had leased the tank car, filled it with acrylonitrile, and delivered it to the Missouri Pacific Railroad for transport to the Chicago suburbs. The leak occurred while the ca...

BACKGROUND The formation of intramolecular hydrogen bonds (IHBs) may induce the remarkable changes in molecular physicochemical properties. Within the framework of the extended solvent-contact model, we investigate the effect of implementing the IHB interactions on the accuracy in estimating the molecular hydration free energies. RESULTS The performances of hydration free energy functions inc...

In the present study, we aimed to determine the differences in body image along with anxiety and depression levels, and also to evaluate their impact on disability parameters in patients with hepatitis B.Our study comprised 77 patients with hepatitis B (n = 41, chronic active patients; n = 36, patients with inactive hepatitis B) and 53 healthy individuals (control group). Enrolled patients resp...
