(2) If tracer is introduced into the carotid artery after osmotic treatment, brain uptake is increased by a net factor of 50 (a factor of 70 due to elevation of PA, multiplied by 7 due to infusion by the carotid route) as compared to uptake by normal, untreated brain with infusion into a peripheral vein.
(3) Whole-virus vaccines prepared by Merck Sharp and Dohme (West Point, Pa.) and Merrell-National Laboratories (Cincinnati, Ohio) and subunit vaccines prepared by Parke, Davis and Company (Detroit, Mich.) and Wyeth Laboratories (Philadelphia, Pa.) were given intramuscularly in concentrations of 800, 400, or 200 chick cell-agglutinating units per dose.

(5) We have shown that human monocytes can synthesize both urokinase-type PA (u-PA) and tissue-type PA (t-PA).
(6) A variant t-PA (G K1 K2 P), which contained only one of the two fibrin binding sites, i.e.
(7) Patients with inflammatory bowel disease showed decreased tissue-type plasminogen activator antigen release (t-PA Ag), no significant Von Willebrand antigen release (vWF Ag), and a residual plasminogen activator inhibitor activity (PAI activity) after venous occlusion.
(8) Proper function of proteinases such as PA may require focusing of activity on a cellular level.
(9) It was then determined whether reducing the PA wedge pressure during exercise with prazosin (9 patients) or dobutamine (6 patients) reduced ventilatory levels toward normal.
(10) A similar concentration of estradiol had no effect on PA activity of the myocytes.
(11) Plasminogen activator inhibitor-1 (PAI-1), the primary physiological inhibitor of tissue-type plasminogen activator (t-PA) in plasma, is a serine proteinase inhibitor (serpin) that forms a 1:1 stoichiometric complex with its target proteinase leading to the formation of a stable inactive complex.
(12) In 130 patients, who were considered to be anti-HTLV-I positive or negative by the PA method, we compared the anti-HTLV-I detection rates and the specificity of the following three EIA methods: the Ei-test ATL and two new EIA methods using different recombinant antigens which recognize different sites.
(13) Plasminogen activator inhibitor (PAI-I) rapidly inactivates tissue plasminogen activator (t-PA) and urokinase (UK) with nearly identical association rate constants.
(14) Heart block occurred in 214 patients (12%); 113 (6.3%) had heart block on presentation and 101 (5.7%) developed heart block in the 24 h after treatment with rt-PA.
(15) The frequency spectra of transmission coefficients for ultrasound passing through a sheet of gas-filled micropores have been measured using incident waves with amplitudes up to 2.4 x 10(4) Pa.
(16) In testing the hypothesis that Lp(a) can competitively inhibit plasma clot lysis mediated by plasmin, the present study shows that Lp(a) significantly enhanced plasma clot lysis mediated by streptokinase or t-PA.
(17) The in vivo hepatic lipid peroxide content of rats was increased by aspirin or 4-pentenoic acid (4-PA) administration but was decreased by clofibrate (CPIB) administration.
(18) The predominant u-PA binding protein isolated from whole cell detergent extracts migrated with a molecular mass of approximately 36 Kd using affinity chromatography.
(19) These studies demonstrate that alpha-thrombin is a potent stimulus for human PLD-mediated PA formation and that cyclic adenosine nucleotides modulate agonist-induced cellular PLD activity.
(20) From the stress-strain curve the following values were selected: strain, stress, and slope at 80 mmHg equivalent pressure (1 mmHg = 133.3 Pa); maximum stress, strain, and slope; and breaking stress, strain, and slope if the sample broke.
Picoampere
Definition:
Example Sentences:
(1) Stimulus-evoked IPSCs varied in amplitude from less than ten to hundreds of picoamperes.
(2) The receptor neurons had high input resistances, and action potentials could be elicited by picoampere amounts of depolarizing current.
(3) Calcium- and depolarization-dependent spontaneous currents of several to hundreds of picoamperes occurred with rapid rise times of 0.8 to 3 milliseconds and decays at least ten times as long.
(4) A device which can generate rectangular currents in the picoampere range is described.
(5) From these field measurements, we infer that each weeted pollen drives a steady current of a few hundred picoamperes through itself.
