time

 [tīm]
a measure of duration. See under adjectives for specific times, such as bleeding time.
activated partial thromboplastin time (APTT, aPTT) the period required for clot formation in recalcified blood plasma after contact activation and the addition of platelet substitutes such as brain cephalins or similar phospholipids; used to assess the coagulation pathways. A prolonged aPTT can indicate a deficiency of any of various coagulation factors, including factors XII, XI, IX, VIII, X, V, and II, and fibrinogen.
AEC minimal response time the shortest duration at which x-ray exposure can be terminated by automatic exposure control.
atrioventricular sequential time a fixed nonprogrammable interval that extends from the atrial stimulus to the ventricular stimulus.
bleeding time the time required for a standardized wound to stop bleeding; used as a test for platelet disorders; see also bleeding time.
circulation time the time required for blood to flow between two given points; see also circulation time.
clotting time (coagulation time) the time required for blood to clot in a glass tube; see also clotting.
cold ischemia time the time between the placement of a traumatically amputated body part in ice and the time of surgical replantation.
inertia time the time required to overcome the inertia of a muscle after reception of a stimulus.
ischemia time the total time between traumatic amputation of a limb or portion of a limb and its surgical reimplantation; it is the sum of warm and cold ischemia times.
minimal response time in radiology, the shortest possible exposure time for an x-ray film to be exposed automatically.
one-stage prothrombin time prothrombin time.
prothrombin time see prothrombin time.
real time a term used to describe a recording device that shows events simultaneously to their occurrence.
thrombin time the time required for plasma fibrinogen to form thrombin; see also thrombin time.
warm ischemia time the time interval between traumatic amputation of a limb or part and its placement on ice.

cir·cu·la·tion time

the time taken for the blood to pass through a given circuit of the vascular system, for example, the pulmonary or systemic circulation, from one arm to another, from arm to tongue, or from arm to lung; it is measured by the injection into an arm vein of a substance, such as sodium dehydrocholate, ether, fluorescein, histamine, or a radium salt, which can be detected when it arrives at another point in the vascular system.

cir·cu·la·tion time

(sĭrkyū-lāshŭn tīm)
Duration elapsed for blood to pass through a given circuit of the vascular system; measured by injection into an arm vein of a substance, which can be detected when it arrives at another point in the vascular system.

Table 4 shows the correlation between each circulation time in FA and the retinal arteriosclerosis by Scheie classification.
Table 5 shows the results of the single regression analysis of the relationships among each circulation time in FA and the three sections of MBR in the ONH.
The results of the single regression analysis between each type of circulation time in FA and the subjects' clinical characteristics are shown in Table 6.
The circulation time of liposomes coated with 1.3% mol of 20 kDa PVA-R was comparable to that of liposomes coated with 8% mol of 2 kDa PEG-1,2-distearoyl-sn-glycero-3-phosphoethanolamine (PEG-DSPE).
PEG2-PE was more efficient in improving the blood circulation time than PEG-PE at a low content (3% mol), whereas at high molar ratio (7% mol) their effect on liposome blood clearance is almost identical.
In a previous study (19), increased cross clamping time was found to be a predictor of increased coronary events including mortality in patients undergoing CABG for LMCA disease and extracorporeal circulation time was very close to be significant as such a predictor.
* Both issuing coins and issuing currency notes lower the government's effective cost of borrowing from the public, by approximately the value of the coin or currency notes in circulation times the interest rate that the government pays on its debt.
The ease with which small particles, with sufficiently long circulation times and carrying peptides that target and treat pathological tissue, can be constructed by self-assembly is an important advantage." (ANI)
