Asthma, diabetes, hypertension, or major depression are non-communicable diseases (NCDs) and impose a major burden on global health. Stress is linked to both the causes and consequences of NCDs and it has been shown that biofeedback-based breathing trainings (BBTs) are effective in coping with stress. Here, diaphragmatic breathing, i.e. deep abdominal breathing, belongs to the most distinguishe...

Dojo loach, Misgurnus anguillicaudatus is a freshwater fish species of the loach family Cobitidae, using its posterior intestine as an accessory air-breathing organ. Little is known about the molecular regulatory mechanisms in the formation of intestinal air-breathing function of M. anguillicaudatus. Here high-throughput sequencing of mRNAs was performed from six developmental stages of posteri...

Understanding sex differences in the qualitative dimensions of exertional dyspnea may provide insight into why women are more affected by this symptom than men. This study explored the evolution of the qualitative dimensions of dyspnea in 70 healthy, young, physically active adults (35 M and 35 F). Participants rated the intensity of their breathing discomfort (Borg 0-10 scale) and selected phr...

Tidal breathing, and especially deep breathing, is known to antagonise bronchoconstriction caused by airway smooth muscle (ASM) contraction; however, this bronchoprotective effect of breathing is impaired in asthma. Force fluctuations applied to contracted ASM in vitro cause it to relengthen, force-fluctuation-induced relengthening (FFIR). Given that breathing generates similar force fluctuatio...

PURPOSE Adjuvant radiotherapy of breast cancer using a photon tangential field incurs a risk of late heart and lung toxicity. The use of free breathing (FB), expiration breath hold (EBH), and deep inspiration breath hold (DIBH) during tangential breast radiotherapy as a means of reducing irradiated lung and heart volume was evaluated. METHODS In 10 women with left-sided breast cancer (mean ag...

In patients with hypertension, volitional slowing of the respiratory rate has been purported to reduce arterial pressure via withdrawal of sympathetic tone. We examined the effects of paced breathing at 7, 14, and 21 breaths/min, with reciprocal changes in tidal volume, on muscle sympathetic nerve activity, forearm blood flow, forearm vascular conductance, and blood pressure in 21 men and women...

BACKGROUND Aerosol production during normal breathing is often attributed to turbulence in the respiratory tract. That mechanism is not consistent with a high degree of asymmetry between aerosol production during inhalation and exhalation. The objective was to investigate production symmetry during breathing. METHODS The aerosol size distribution in exhaled breath was examined for different b...

This study aims to identify the effectiveness of Active Cycle Breathing technique (ACT) nursing intervention in overcoming problem an ineffective airway through a series respiratory control, deep breathing and sputum expulsion techniques. The method used is single case study. Respondents this were patients with active pulmonary tuberculosis broad lesions bronchiectasis. results showed that afte...

background: endotracheal or tracheostomy tube in mechanically ventilated patients disturb verbal communication with others. therefore, patients are frustrated of requesting for their needs or problems related to artificial breathing. therefore investigating self-experiences of these patients can be applied in providing them with a better care by clinical personnel. methods: this is a qualitativ...

Background: One of the causes malocclusion in developing children is practice mouth breathing. Morphological disturbances may occur during growth phase with chronic This resulting unfavorable development dentofacial and craniofacial complexes. Mouth breathing as a condition has come to attention health care professionals. Malocclusion incidence will be decreased eventually eliminated early iden...
