background and objective: asthma is the most common chronic disease of childhood. the disease is caused by a temporary blockage of airflow due to chronic inflammation of the airways . one of the conditions that often occur with asthma and exacerbate disease, is gastroesophageal reflux. the aim of this study is to evaluate the role of acid suppressing therapy in patients with refractory asthma. ...
abstract background: triple therapy with a proton pump inhibitor, clarithromycin and amoxicillin and quadruple therapy with a proton pump inhibitor, bismuth citrate, metronidazole and amoxicillin have been proposed in maastricht 2000 as the optimal treatment of helicobacter pylori infection. we aimed to compare these two regimens in iranian pediatric patients. methods: a randomized clinical tri...
Results are presented demonstrating that the backbone of the active site lysine of bacteriorhodopsin undergoes light-induced structural alterations during bacteriorhodopsin-mediated light-induced proton pumping. This conclusion is based on difference Fourier transform infrared spectroscopy of isotopically labeled bacteriorhodopsin. The data demonstrate that the backbone carbonyl of lysine achie...
The crystal structures of two cytochrome c oxidases, one bacterial and one mammalian, offer insights into their roles in oxygen chemistry and as proton pumps.
