airway

1. an air route, esp one that is fully equipped with emergency landing fields, navigational aids, etc.
2. a passage down which air travels from the nose or mouth to the lungs
3. Med a tubelike device inserted via the throat to keep open the airway of an unconscious patient

Airway

 

an approved route for regular flights of transport planes. The route is provided with maintained airfields and with the necessary ground-support equipment (radio beacons, air lane identification markers, and the like) to insure safe takeoff and landing. Civil aviation flights are generally carried out on airways. In some special cases—for instance, when servicing expeditions or rendering emergency medical assistance—flights are carried out independent of any airway. The first Soviet airway was inaugurated in 1923 between Moscow and Nizhnii Novgorod (now called Gorky). In 1968 more than 2,500 airways (with a total extent of about 500,000 km) constituted the consolidated network of the USSR Aeroflot system, linking about 3,500 cities and populated points within the country and 44 foreign countries.

A control area, or a portion thereof, established in the form of a corridor (ICAO). An airway is equipped with radio navigation aids. It is a path through navigable airspace designated by the appropriate authority within which air traffic services are provided.

The pipette solution contained 6 mmol/L NaCl, 135 mmol/L CsCl, 2 mmol/L Ca[Cl.sub.2], 3 mmol/L MgATP, 2 mmol/L TEA-Cl, 5 mmol/L EGTA, and 10 mmol/L HEPES (pH7.2 (CsOH)).
We employ EGTA to analyze this complex security game, as obtaining an analytical solution would be impractical.
Experiments using ATR-FTIR were performed to determine if lysozyme was adsorbed onto CFA particle surfaces and whether the adsorption was inhibited by CFA pretreatment with EGTA. The ATR-FTIR flow system, equipped with a horizontal ATR crystal (AMTIR crystal element; Pike Technologies), was used in all of the experiments and has previously been described in detail (Borcherding et al.
(a) Thrombin-induced [[Ca.sup.+2]]i increase is partially prevented by EGTA (0.25 mM) and abolished by thapsigargin (Tg; 2 [micro]M) + EGTA.
The maximum rates of reaction, [V.sub.max], in EGTA and 50 [micro]M [Ca.sup.2+] were 230.0 and 54.1 nmol [min.sup.-1] [mg.sup.-1] myosin, respectively.

To examine, the role of [[Ca.sup.2+]]i in response to iron, the effect of EGTA, an extracellular [Ca.sup.2+] chelator, was investigated.
Role of K+-ATP channel and calcium was evaluated in the presence of Calcium chloride (1.28 mM), EGTA (1 mM), Nifedipine (20 M) and KCl (30 mM, Depolarising concentration).
The RRBC were resuspended with GVBS-Mg-EGTA buffer (containing 0.1% gelatin; 3.12 mM Diethylbarbituric acid; 1.82 mM Diethylbarbituric acid sodium salt; 145.45 mM NaCl; 1 mM MgCl2; 20 mM Ethylene glycol-bis(2-aminoethylether)-N,N,N',N'-tetraacetic acid (EGTA); pH 7.45; conductivity 13.5 mS) to a final concentration 0.5%.
The group travel sector is estimated to account for almost 25% of all European visitor numbers and the EGTA awards are designed to showcase the continent's best providers.
BAPTA binds calcium quickly before it can diffuse from its entry point, while EGTA binds calcium more slowly, allowing it to diffuse a small distance away.
