Microinjections of D,L-homocysteic acid (DLH) were used to test the hypothesis that neuronal activation within the Botzinger complex area can modify the spatiotemporal characteristics of the cough reflex in 17 spontaneously breathing pentobarbitone anesthetized cats. DLH (50 mM, 1.25-1.75 nmol, 9 cats) reduced the number (P<0.01) of coughs and expiratory amplitude of abdominal electromyographic...

A 78-year-old female patient was admitted to the emergency department with severe abdominal pain and respiratory distress. In Computer Tomography (CT) examination of patient; It observed that there a hernia in left leaf diaphragm stomach, spleen intestines were protruding pleural space up clavicle. patient's anamnesis; breathing difficulty has been going on for many years increased recent days ...

The pelvis of crocodilians is highly derived in that the pubic bones are isolated from the acetabulum and are attached to the ischia via moveable joints. We examined the possible role of this unusual morphology in lung ventilation by measuring ventilation, abdominal pressure and the electrical activity of several abdominal and pelvic muscles in the American alligator (Alligator mississippiensis...

Title: Acceleration sensors in abdominal wall position as a non-invasive approach to detect early breathing alterations induced by intolerance of increased airway resistance Authors: Thomas Breuer ([email protected]) Christian Bruells ([email protected]) Rolf Rossaint ([email protected]) Henning Steffen ([email protected]) Catherine Disselhorst-Klug ([email protected]...

Thoracoabdominal motion and intrathoracic (oesophageal), intra-abdominal (gastric), and transdiaphragmatic pressures were measured during tidal breathing in 20 erect subjects--six normal, seven, with emphysema, and seven with fibrosing alveolitis. In normal subjects all diameters increased synchronously during inspiration and were accompanied by rises in abdominal and transdiaphragmatic pressur...

Effects of kainic acid lesions in the medullary raphe midline on reflex expirations induced mechanically from the trachea were examined. Spontaneously breathing rabbits were anesthetized by ketamine and xylazine i.m., followed by pentobarbitone i.v. Excitatory neurotoxin kainic acid (2 mg/ml in artificial CSF, total volume of 55-100 nl) was pressure microinjected into the medullary midline, ros...

growing number of evidence indicates that individuals' motivational structure - the patterning of an individual's way of relating to goals - plays an important role in increasing the risk of alcohol use. adaptive motivational structure which includes pursuit of important, subjectively attainable, alcohol-unrelated goals is inversely related to substance use. the strength of this relationship in...

the effect of motivational self-regulatory strategies on l2 learners’ achievement has scarcely been examined within the context of our country, iran. this study is concerned with examining the relationship between motivational self-regulatory strategies and their l2 reading and l2 writing achievement. it also explores the relationship of motivational self-regulatory strategies and use of langua...
