The aim of this study was to determine whether spontaneous respiration influences pulmonary artery input impedance, a question that has received little attention in the literature. Impedance values were assessed during three different phases of the respiratory cycle, namely inspiration, expiration and postexpiration (i.e. the null respiratory flow period between expiration and the next inspirat...

On the basis of innovation resistance theory (IRT) and technology acceptance model (TAM), this study explores preference college students for keyboard typing over speech input document processing. Results showed that functional barriers (i.e., usage, value, risk barriers) psychological tradition image positively affect users’ to change. Perceived ease use perceived usefulness influence intentio...

This study was designed to examine the effects of lyophilized red delicious apple peel (RDP) on the action potentials (APs) and the input resistance-threshold current relationship. The experiments were performed on isolated papillary heart muscles from healthy male rats, healthy male rats treated with RDP, diabetic male rats, and diabetic male rats treated with RDP. The preparation was superfus...

Total respiratory input (Zin) and transfer (Ztr) mechanical impedances were measured from 4-30 Hz in 9 patients with severe chronic obstructive pulmonary disease (COPD) and in 12 healthy subjects. Zin was obtained by applying a pressure input around the head to minimize transmural pressure across extrathoracic airway walls, and Ztr was obtained with a pressure input at the chest. In agreement w...

Running title: Synaptic strength regulation mediated by GABA receptors. The role of GABA A and GABA B receptors in modulation of excitatory synaptic transmission between motoneurons and terminals from dorso-lateral funiculus (DLF) was studied in in-vitro spinal cord slices of adult turtles. Muscimol –a GABA A receptor agonist-depressed the monosynaptic excitatory postsynaptic potential (EPSP) i...

The role of GABAA and GABAB receptors in modulation of excitatory synaptic transmission between motoneurons and terminals from dorsolateral funiculus (DLF) was studied in in vitro spinal cord slices of adult turtles. Muscimol--a GABAA receptor agonist--depressed the monosynaptic excitatory postsynaptic potential (EPSP) induced by stimulation of the DLF and shortened its duration. The input resi...

The aim of the study was to determine the influence of the presence or the absence of antibiotic input on the emergence and maintenance of resistance in commensal bacteria from food producing animals. The research material constituted E. coli isolates from two animal species: swine at different age from one conventional pig farm with antibiotic input in young pigs and from beef and dairy cattle...

this study was designed to find which one of the three different presentations, i.e. input, input-output, and output-input, will be more effective in iranian efl learners' vocabulary acquisitions. to this end, first 54 out of 64 female students, aged from 19 to 23 years, with an average of 21, were selected out of starter-level efl learners at the university of tarbiat moalem in bandar abb...
