Proton conduction in materials comprising conducting domains with widths less than 6nm

Proton-conducting Oxides

■ Abstract The structural and chemical parameters determining the formation and mobility of protonic defects in oxides are discussed, and the paramount role of high-molar volume, coordination numbers, and symmetry are emphasized. Symmetry also relates to the structural and chemical matching of the acceptor dopant. Y-doped BaZrO 3-based oxides are demonstrated to combine high stability with high...

Proton Conduction through gp91phox

Previous Perspectives in the Journal of General Physiology have considered (a) the different advantages of two models of ion channel permeation and (b) whether ryanodine receptor adaptation might arise from flash photolysis. Each argument, over the choice of model or influence of technique, is an example of a classic scientific dispute. Here we turn to another hoary old problem—the identificati...

Diagnostic Accuracy of Positron Emission Mammography with 18F-fluorodeoxyglucose in Breast Cancer Tumor of Less than 20 mm in Size

Objective(s): To investigate the diagnostic accuracy of positron emission mammography (PEM) and positron emission tomography/computed tomography (PET/CT) for small breast tumors of less than 20 mm in size.Methods: The study was conducted on a total of 100 subjects (i.e., 50 patients with pathologically proven breast cancer and 50 normal cases of medical screening). The total number of tumors wa...

The Effects of Model-Based Educational Intervention on Self-medication Behavior in Mothers with Children less than 2- year

Background: Self-medication by people is one of the major issues in the world that can be lead to numerous medical and economic problems, this especially issue in children under 2 years who are at the age of growth and development have great importance. The aim of this study was investigate the effects of model-based educational interventions on self-medication behavior in mothers with children...
