BACKGROUND Although the MAZE procedure allows for the recovery of sinus rhythm and left atrial (LA) mechanical function in the great majority of patients with chronic atrial fibrillation (AF), the effects of MAZE on the precise LA geometry and wall motion remain to be elucidated. We hypothesized that LA size and mechanical function in patients with chronic AF and mitral valvular disease are wel...
Droplets emitting surface-active chemicals exhibit chemotaxis toward low-pH regions. Such droplets are self-propelled and navigate through a complex maze to seek a source of acid placed at one of the maze's exits. In doing so, the droplets find the shortest path through the maze. Chemotaxis and maze solving are due to an interplay between acid/base chemistry and surface tension effects.
objective: walnut (juglans regia) is a domestic fruit of iran. walnut kernel (wk) has many beneficial constituents such as unsaturated fatty acids, antioxidants, and vitamin e. scientific studies have shown that fatty acids and vitamin e can modulate learning and memory processes. the aim of the present work was to study effects of walnut consumption by mothers during pregnancy and lactation on...
introduction: several studies indicate that estrogen use increase performance on some tests of cognition especially in postmenopausal women. these steroids have many side effects, thus, other estrogenic agents with fewer side effects are needed to develop alternative treatment strategies. the main objection of this study was to evaluate the effects of different doses of dietary soy meals (with ...
