BACKGROUND Contrary to adaptive support ventilation (ASV), prolonged totally controlled mechanical ventilation (CMV) results in the absence of diaphragm activity and causes ventilator-induced diaphragmatic dysfunction. Because maintaining respiratory muscles at rest is likely a major cause of ventilator-induced diaphragmatic dysfunction, ASV may prevent its occurrence in comparison with CMV. Th...
AIM To compare electromyographic (EMG) activity in young-adult subjects with different breathing types. METHODOLOGY This study included 50 healthy male subjects with complete natural dentition, and no history of orofacial pain or craniomandibular-cervical-spinal disorders. Subjects were classified into two groups: upper costal breathing type, and costo-diaphragmatic breathing. Bipolar surface...
The spontaneous contractility of FITC-dextran-filled lymphatics at the periphery of the pleural diaphragm was documented for the first time "in vivo" in anesthetized Wistar rats. We found that lymphatic segments could be divided into four phenotypes: 1) active, displaying rhythmic spontaneous contractions (51.8% of 197 analyzed sites); 2) stretch-activated, whose contraction was triggered by pa...
Delayed Presentation of Traumatic Diaphragmatic Hernia: The Evaluation of Surgical Treatment Results
Introduction: Diaphragmatic hernia could be caused by congenital disorders, blunt trauma or penetrating injuries. The diagnosis of traumatic diaphragmatic hernia is normally neglected during the first presentation leading to late complications and considerably increased mortality and morbidity among the patients. Materials and Methods: In this retrospective, descriptive study, we reviewed the m...
We evaluate the impact of changes in solar activity on three significant human psychophysiological parameters: skin conductance, electromyography (EMG), and share abdominal diaphragmatic breathing overall ventilation. Variations affecting psychophysiology due to directly document assertion that psychology, behavior, decision-making all reflect geomagnetic field alterations stem from variable ac...
The purpose of this study was twofold: (i) to investigate if sprint-interval training (SIT) alters myosin heavy chain (MyHC) isoform composition and bioenergetic properties within the rat diaphragm, and (ii) to determine if mild normobaric hypoxia would enhance the effects of SIT-induced diaphragmatic adaptation. Male Wistar rats (8 weeks old) were randomly assigned to one of four groups (n = 7...
The effects of nicardipine, a calcium channel blocker, on diaphragmatic fatigue were studied in 20 anaesthetized, mechanically ventilated dogs divided into two groups: control group (Group C, n = 10) and nicardipine group (Group N, n = 10). Diaphragmatic fatigue was induced by intermittent supramaximal electric stimulation to bilateral phrenic nerves at a frequency of 20 Hz for 30 min. In Group...
