The purpose of this study was to investigate the roles of branchial and gas bladder reflex pathways in the control of gill ventilation and air-breathing in the bowfin Amia calva. We have previously determined that bowfin use two distinct air-breathing mechanisms to ventilate the gas bladder: type I air breaths are characterized by exhalation followed by inhalation, are stimulated by aquatic or ...

Background: Chronic obstructive pulmonary disease, which is usually caused by harmful particles or gases, associated with persistent respiratory symptoms. Aim: To determine effects of controlled breathing techniques for muscle strengthening and functional capacity. Study Design: Randomized control trial. Methodology: was conducted at Services Hospital Lahore duration 6months. Patients (n=48) we...

Flexible Metal–Organic Frameworks In article number 2301122, Eun Seon Cho and co-workers design highly flexible metal–organic framework (MOF)-based proton conductors to control the breathing behavior hydrogen-bonding networks with structural transformation through simultaneous introduction of carriers functional groups. Imidazole-loaded MIL-88B without groups exhibits super conductivity excepti...

The effect of respiration on the cerebrovascular response to elevated intracranial pressure (ICP) was studied in anesthetized dogs. Total and regional cerebral blood flows were measured using labelled microspheres. In spontaneously breathing dogs total and regional cerebral blood flows increased when cerebral perfusion pressure was reduced to 20 mm Hg. The increase in regional flows was greater...

BACKGROUND Respiratory involvement in neuromuscular disorders may contribute to impaired breathing-swallowing interactions, swallowing disorders and malnutrition. We investigated whether the use of non-invasive ventilation (NIV) controlled by the patient could improve swallowing performances in a population of neuromuscular patients requiring daytime NIV. METHODS Ten neuromuscular patients wi...

Automatic continuous positive airway pressure (APAP) devices adjust the delivered pressure based on the breathing patterns of the patient and, accordingly, they may be more suitable for patients who have a variety of pressure demands during sleep based on factors such as body posture, sleep stage or variability between nights. Devices from different manufacturers incorporate distinct algorithms...

Question: Does breathing training improve respiratory symptoms, quality of life and objective markers of disease severity in adults with asthma? Design: Randomised controlled trial. Setting: Ten general practitioner (GP) practices in Leicester, UK. Participants: Adults treated for asthma in a GP practice with moderate impairment of asthma-related health status, defined as a score less than 5.5 ...

Breathing strategy is generally regarded as an important factor in operatic singing, because it is assumed to affect phonation. If so, professional singers should exhibit well-controlled, replicable breathing movements when repeating the same phrase. The purpose of the present study was to investigate to what extent professional opera singers show a consistent, exhalatory breathing behavior in ...

Introduction The III Brazilian Consensus on Rhinitis (2012) defines allergic rhinitis as a nasal mucosa inflammation, mediated by immunoglobulin E, after exposure to allergens. The classic signs and symptoms of allergic rhinitis are nasal obstruction, watery rhinorrhea, sneezing, and nasal itching, often reversible either spontaneously or with treatment, and mouth breathing (breathing predomina...

A variety of chest physiotherapy techniques are used following abdominal and thoracic surgery to prevent or reduce post-operative complications. Breathing techniques with a positive expiratory pressure (PEP) are used to increase airway pressure and improve pulmonary function. No systematic review of the effects of PEP in surgery patients has been performed previously. The purpose of this system...
