We examined the effect of oral breathing on respiratory movements, including the number of respirations and the movement of the thoracic wall at rest and while chewing gum. Forty normal nose breathers were selected by detecting expiratory airflow from the mouth using a CO2 sensor. Chest measurements were recorded using a Piezo respiratory belt transducer, and electromyographic (EMG) activity of the masseter and trapezius muscles were recorded at rest and while chewing gum during nasal or oral breathing. Oral breathing was introduced by completely occluding the nostrils with a nose clip. During

Therefore, we determined whether PBMC mitochondrial respiration could be used as a marker of skeletal muscle mitochondrial respiration in young healthy men and whether PBMC mitochondrial respiration responds to short-term training.

In subjects with sinus rhythm, respiration has a profound effect on heart rate variability (HRV) at high frequencies (HF).

However, previous investigations have not considered the possibility that respiration might influence HRV at lower frequencies.

Streszczenie:

Pulmonary gas exchange is a complex component of respiratory physiology. For many students, the movement of unseen gases can seem abstract and confusing. The “Gas Exchange Game” is a novel board game designed for use in a second-semester anatomy and physiology course. Students apply textbook knowledge of the laws of gas exchange and use the game board and pieces to see concrete examples of how gases move in the human body.

Abstract Two different cyanobacteria, Anabaena CH 1 and CH2, were isolated from Taiwan paddy soils. Both strains can grow well with daily dilution method. Anabaena CH1 shows a blue-green color and Anabaena CH2 a green brownish one. Nitrogenase activity decreased as cultures were transferred from light to dark. When a darkened culture was placed again into the light, nitrogenase activity recovered within two hours, but not in the presence of chloramphenicol. Energy supply for nitrogenase within both strains was different. Nitrogenase activity of Anabaena CH1 was light-dependent and oxygen in he

The dynamics of the respiratory and cardiovascular systems were studied by continuously slowing respiration from 0.46 to 0.05 Hz. The time-frequency distribution and global spectral analysis were used to assess the R-R interval (R-R) and the systolic and diastolic blood pressure fluctuations in 16 healthy subjects. During rest, the nonrespiratory-to-respiratory frequency ratios were not affected by occasional slow breathing, whereas the low- (0.01–0.15 Hz) to high- (0.15–0.3 Hz) frequency indexes for blood pressure were increased (P < 0.05). The respiratory fluctuations in R-R and the systo

Previously, we showed that oxidant exposure in renal proximal tubular cells (RPTC) induces mitochondrial dysfunction mediated by PKC-ε. This study examined the role of ERK1/2 in mitochondrial dysfunction induced by oxidant injury and whether PKC-ε mediates its effects on mitochondrial function through the Raf-MEK1/2-ERK1/2 pathway. Sublethal injury produced by tert-butylhydroperoxide (TBHP) resulted in three- to fivefold increase in phosphorylation of ERK1/2 and p38 but not JNK. This was followed by decreases in basal and uncoupled respirations (41%), state 3 respiration and ATP production cou

Heart rate during sinus rhythm is modulated through the autonomic nervous system, which generates short-term oscillations. The high-frequency components in these oscillations are associated with respiration, causing sinus arrhythmia, mediated by the parasympathetic nervous system. In this study, we evaluated whether slow, controlled respiration causes cyclic fluctuations in the frequency of the fibrillating atria. Eight patients (four women; median age 63 yr, range 53–68 yr) with chronic atrial fibrillation (AF) and third-degree atrioventricular block treated by permanent pacemaker were studie

The effects of slow and rapid cooling methods on the postharvest physiology of Yali pears during ice temperature (-0.5°C) storage were investigated. Respiration rate, ethylene production, browning index and polyphenol oxidase(PPO) activity were used to evaluate the quality of Yali pears. The results showed that the slow cooling treatment decreased the levels of respiration rate，ethylene production，and PPO activity of Yali pears, and delayed the occurrence of the respiration, ethylene, and PPO activity peak compared to the rapid cooling treatment. The browning indexes of Yali pears with slow co

During obstructive sleep apnea (OSA), respiratory activation of upper airway muscles, particularly genioglossus, is ineffective during sleep. Functional electrical stimulation (FES) of muscles reportedly reduces the number and length of OSAs. Our goals were to examine the effect of FES on sensation during wakefulness and on OSA events. Studies were performed in 11 subjects: 4 healthy asymptomatic subjects and 7 patients with OSA. Surface electrodes placed on the submental region produced discomfort; however, during sleep, the stimulus intensity producing arousal was significantly greater than

Spontaneously hypertensive rats (SHR) have an activated brain angiotensin system. We hypothesized 1) that ventilation (V˙) would be greater in conscious SHR than in control Wistar-Kyoto (WKY) rats and 2) that intravenous infusion of the ANG II-receptor blocker saralasin would depress respiration in SHR, but not in WKY. Respiration and oxygen consumption (V˙o 2) were measured in conscious aged-matched groups ( n = 16) of adult female SHR and WKY. For protocol 1, rats were habituated to a plethysmograph and measurements obtained over 60–75 min. After installation of chronic intravenous catheters
