Cheyne-Stokes respiration is also known as periodic respiration, with cycles of respiration that are increasingly deeper then shallower with possible periods of apnoea. Although 50% of patients with moderate-to-severe congestive heart failure are affected by significant Cheyne-Stokes respiration, its exact pathophysiology remains unclear. [1]Typically, over a period of one minute, a 10to 20-sec...

Respiration signal of the vital signs is an important parameter in clinical parts. To extract the respiration signal from PPG signal for mobile healthcare system is difficult because the bands of the motion artifacts and respiration in the frequency domain are overlapped. This study to improve this problem suggested a respiration extraction method using the independent component analysis and ev...

Affect has been shown to influence respiration in people. This article takes this insight and proposes a real-time model to express affect through respiration in virtual humans. Fourteen affective states are explored: excitement, relaxation, focus, pain, relief, boredom, anger, fear, panic, disgust, surprise, startle, sadness and joy. Specific respiratory patterns are described from the literat...

Oral respiration is considered as an important etiological factor of anomalies in the orofacial region. Many studies have shown a correlation between the manner of respiration and antero-posterior relation of the jaws. Aim of this study was to find out the frequency of patients with oral respiration and to determine the reason for oral respiration, as well as to examine different anomalies caus...

BACKGROUND For more than 1500 years, the status of knowledge concerning the physiology of human respiration has remained almost unchanged. In the 18th century, the French chemist Antoine-Laurent de Lavoisier conducted breathing experiments on human and animal respiration. METHODS The main bibliographic sources concerning Lavoisier's life and work on respiration have been investigated and anal...

We compared action of Cd(2+), Hg(2+), and Cu(2+) on isolated rat liver mitochondria in the absence of added Ca(2+) and P(i). The heavy-metal ions produced dose-dependently: (1) enhanced membrane permeabilization manifested in mitochondrial swelling and activation of basal respiration, (2) inhibition of uncoupler-stimulated respiration, and (3) membrane potential dissipation. Among the metals, C...

The respiration rate and respiratory quotient of mature tomato (Solanum lycopersicum L. cv. ‘Himsona’) fruits harvested at the turning stage were determined under closed system at 5, 10, 15, 20, 25 and 35 °C (ambient) temperatures. The rate of respiration was higher at the start of the experiment and gradually declined as the storage period prolonged, before becoming almost constant. The steady...
