BACKGROUND Gelatin tannate is a mixture of tannic acid and gelatin. Tannic acid has astringent properties, due to its capacity to form protein-macromolecular complexes, as well as antibacterial and antioxidant properties. However, little is known about its anti-inflammatory properties. PURPOSE To evaluate the anti-inflammatory activity of gelatin tannate(More)
Cells that utilize molecular oxygen generate highly reactive oxygen-derived free radicals. Endogenous cellular oxidants inactivate oxidant free radicals and protect aerobic cells from oxidant injury. Glutathione, glutathione reductase, and superoxide dismutase are key components of this antioxidant defense. Inhibition of antioxidant components would be(More)
The aim of the present study was to compare the effectiveness and the safety of different topical agents (glycolic acid, mandelic acid, and grape juice acid mixture) in skin exfoliation by objective instrumental methods. To evaluate the exfoliating effects of these substances, a new experimental in vivo protocol based on DHA (dihydroxyacetone)-induced skin(More)
Using Near Edge X-Ray Absorption Fine Structure (NEXAFS) Spectroscopy, the thickness dependent formation of Lutetium Phthalocyanine (LuPc2) films on a stepped passivated Si(100)2×1 reconstructed surface was studied. Density functional theory (DFT) calculations were employed to gain detailed insights into the electronic structure. Photoelectron spectroscopy(More)
Red blood cells (RBC) possess strong antioxidant activity. We tested whether this activity was sufficient to prevent the oxidative inactivation of alpha 1-antitrypsin (alpha 1-AT) by cigarette smoke. We found that RBC in physiological concentrations completely prevented the inactivation of alpha 1-AT. The major erythrocytic antioxidants, catalase,(More)
The thermoregulatory response to cold exposure was examined in 11 unipolar and 5 bipolar II drug-free outpatients and 12 healthy controls. Subjects were studied in an environmental chamber at 10 C for 60 min. The heat production response was derived from the rate of oxygen consumption measured at 15-min intervals. Rectal and mean skin temperatures were(More)
