Outside JEB iv FLIES SHORT OF BREATH
Functional interpretations of the insect tracheal system – a branched series of tubes supplying oxygen from the environment to every metabolizing tissue in the insect’s body – are plagued by two related myths. The first is that gases move through the tracheal system entirely by diffusion. This idée fixe persists despite many studies showing that, across vast taxonomic distances, insects activel...
متن کاملShort term variability of single breath carbon monoxide transfer factor.
BACKGROUND When monitoring patients with chronic lung disease it is important to distinguish genuine changes in gas transfer over time from natural variability. This study aims to define the coefficient of repeatability for routine measurements of single breath transfer factor (TCO) and transfer coefficient (KCO). METHODS Sixty eight subjects (32 with emphysema, 36 healthy volunteers) had TCO...
متن کاملfeatures of short story in translated and non-translated literature: a polysystemic perspective
ترجمه متون ادبی در دنیای امروز از اهمیت ویژه ای برخوردار است. فرهنگ های مختلف با استفاده از متون ادبی ملل و فرهنگ های دیگر سعی در غنی کردن فرهنگ و ادبیات کشور خود دارند. کشور ما نیز از این قاعده مستثنی نیست. در ایران، ترجمه متون ادبی اروپائی که با دوران مشروطه ایرانی آغاز می شود موجب تغییرات اساسی در فرهنگ، شیوه زندگی و تفکر ایرانیان شده است. در این دوران نه تنها در امورات سیاسی و فکری کشور تغی...
15 صفحه اولBreath, urine, and blood measurements as biological exposure indices of short-term inhalation exposure to methanol.
Due to their transient nature, short-term exposures can be difficult to detect and quantify using conventional monitoring techniques. Biological monitoring may be capable of registering such exposures and may also be used to estimate important toxicological parameters. This paper investigates relationships between methanol concentrations in the blood, urine, and breath of volunteers exposed to ...
متن کاملRapid Restitution of the Lung Functions Following Short-Term Breath- Holding During Moderate Intensity Cycling Exercise
Short periods of breath-holding (BH) occur frequently during various kinds of sports activities. Increased minute oxygen uptake (VO2), increased minute carbon dioxide output (VCO2) and increased minute ventilation (VE) are some of the typical responses just after breaking the BH and resuming breathing and these parameters return to their steady levels over time. This study examined the properti...
