Acetylcholinesterase of Torpedo californica, human serum cholinesterase, and others Takagi et al., 1991; Krejci et al., 1991 ; . Mature hTg is a mixture of both non-covalent and covalent omodimers, having a molecular mass of 330, 000. Post-translational modifications of hTg: glycosilation Carbohydrate contribute about 10 per cent of the Tg mass. Two kinds of oligosaccharide units A and B ; are attached by glycosylamine linkages to asparagine residues of Tg. High-mannose A units contain a variable number 7-9 ; of mannose residues and 2 Nacetylglucosamine residues. Complex B units contain 3 mannose residues and a variable number of N- acetylglucosamine, galactose, fucose, and sialic acid residues Arima et al., 1972 ; . Human Tg also contains C and D oligosaccharide units. C units are linked to serine and threonine by O-glycosidic bonds and contain galactosamine; D units are chondroitin-6sulfate-like oligosaccharides linked to serine and contain a repeating unit of glucuronic acid and galactosamine, plus xylose, galactose, and sulfate Spiro et al., 1977 ; . 90 per cent of the [35S]-sulfate incorporated into human Tg is equally distirbuted in: a ; biantennary B units, containing galactose-3-sulfate, and tri- and tetra-antennary B units containing galactose-3sulfate and N-acetylglucosamine-6-sulfate; b ; chondroitin-6-sulfate-like D units Spiro and Bhoyroo, 1988; Schneider et al., 1988 ; . Post-translational modification of hTg: iodination, sulfation and hormonogenesis Iodoamino acids in hTg include monoiodotyrosine MIT ; , 3, 5-diiodotyrosine DIT ; , and the hormones 3, 5-triiodothyronine T3 ; and 3, 5, thyroxine, T4 ; . Under normal conditions, the iodine level ranges from 10 to 40 moles of iodine atoms per mole of Tg. MIT, DIT and T4 appear to be in precursor-product relationship, in the same order. For an iodine content of 0.5 per cent of the Tg weight 25 moles of iodine atoms per mole of Tg ; , 2.5-3 moles of T4 and less of than 1 mole of T3 are formed per mole of human 12.

Dobutamine thallium echocardiogram
F M o precisely, a logistical function extrapolating the trend recorded between i960 and 1974 was used in the case of first-level schooling. In the case of secondary education, coefficients of the transition between the first and second levels were calculated and extrapolated by means of the same logistical function, and the numbers of school-age children were calculated by projecting primary school-age cohorts. In the case of higher education, transitional coefficients were considered adequate.
Dopamine and dobutamine compatibility
Background--The myocardial uptake of 99mTc-sestamibi is attenuated by dobutamine stress, resulting in underestimation of ischemia. 99mTc-N-NOET ; is a new 99mTc-labeled perfusion agent that is highly extracted by the myocardium by a mechanism different from that defined for 99mTc-sestamibi. We therefore hypothesized that 99mTc-N-NOET uptake would not be attenuated by dobutamine and that 99mTc-N-NOET uptake would be comparable to 201Tl uptake during dobutamine stress. Methods and Results--In 28 open-chest dogs, after placement of a stenosis in the left anterior descending coronary artery that reduced flow reserve by 50%, adenosine 300 g kg 1 min 1; n 15 ; or dobutamine 2.5 to 30 g min 1; n 13 ; was infused. During adenosine stress, the stenotic-to-normal activity ratio for 99mTc-N-NOET was 0.55 0.05. The stenotic-to-normal flow ratio was 0.33 0.04 at the time of 99mTc-N-NOET injection. During dobutamine stress, the stenotic-to-normal 99mTc-N-NOET activity ratio was 0.63 0.04, comparable to the 201Tl activity ratio of 0.59 0.04. The stenotic-to-normal flow ratio was 0.47 0.04 at the time of 99mTc-N-NOET and 201Tl injection. The relationship between 99m Tc-N-NOET uptake and blood flow was comparable for adenosine and dobutamine stress, with no evidence of attenuation of 99mTc-N-NOET extraction by dobutamine. Conclusions--In the presence of coronary stenoses that reduced regional flow reserve, the myocardial uptake of 99m Tc-N-NOET and 201Tl are closely proportional to blood flow during both adenosine and dobutamine stress, suggesting that the adverse effect of dobutamine on 99mTc-sestamibi uptake is a tracer-specific phenomenon rather than a generalized effect. The clinical implication of this finding is that 99mTc-N-NOET might be preferable to 99mTc-sestamibi when used with dobutamine stress for detection of coronary stenoses.

Tion-associated antigen 1 LFA-1 ; , and LFA-3. We observed that recognition of B-lineage tumor lines by CD19-specific CTLs was not impaired by low levels of ICAM-1, LFA-1, and LFA-3 cell surface expression, a functional attribute that is likely a consequence of our high-affinity CD19-specific chimeric immunoreceptor. Furthermore, the CD19-specific CTLs could lyse primary B-ALL blasts. These preclinical observations form the basis for implementing clinical trials using donor-derived CD19-specific T-cell clones to treat or prevent relapse of B-ALL after allogeneic HSCT.

Our intent was to evaluate hemodynamic-induced changes in AVA and their effects on CO calculations by using an established method of dobutamine stimulation. During the dobutamine infusion, we observed a 54.5% 19.6% increase in Vmax, a 50.6% 34.2% increase in SBP, and an associated 4.3% 2.6% increase in AVA. Although there was individual variation in the degree of change in valvular area, the response was in a limited range of 0.6% to 9.7%. The data gathered in this study of the human aortic valve in vivo add to previous observations in animal and in vitro studies. Variation in the area of the nondiseased aortic valve with hemodynamic changes has been suggested by investigations in open chest dogs 9 ; and by studies using cadaveric human aortic valves. In vitro examination by Montarello et al. 10 ; of five aortic valves mounted in a pulsatile pump model demonstrated a considerable degree of flow dependence in AVA. In contrast, Sprigings et al. 11 ; used a similar in vitro model to examine four nondiseased aortic valves and found AVA to be flow dependent, but to a lesser degree. Other studies' results question the flow-dependent properties of the nondiseased aortic valve, especially over a physiologic range of flows 1216 ; . Our results in humans support the model that changes in hemodynamics have only a modest effect on AVA, showing approximately the same degree of variance in AVA as found in vitro by Sprigings et al. 11 ; , as opposed to the large increases reported by Montarello et al. 10.

SURVIVE was a randomized, doubleblind, multicenter, parallel-group study. Randomization was performed by a 2-step procedure FIGURE 1 ; . First, vials containing study drug were assigned a number using randomly permuted blocks. Second, patients were randomized centrally, using an interactive voice response system, to receive levosimendan or dobutamine at a ratio of 1: Randomization was stratified using a biased coin algorithm with previous ADHF and country as factors. During the treatment period, patients were randomized to receive 2 double-blind intravenous infusions: levosimendan and placebo for dobutamine in the levosimendan group or dobutamine and placebo for levosimendan in the dobutamine group. A loading dose of levosimendan 12 g kg ; placebo for levosimendan was administered over 10 minutes, followed by an infusion 0.1 g kg per minute ; for 50 minutes; the rate was increased to 0.2 g kg per minute for an additional 23 hours as tolerated. The infusion of dobutamine or placebo for dobutamine was initiated at a rate of 5 g per minute and could be increased at the discretion of the investigator to a maximum rate of 40 g per minute. The infusion was maintained as long as clinically appropriate minimum of 24 hours ; and was tapered according to each patient's clinical status. Plasma B-type natriuretic peptide BNP ; levels were measured after 1, 3, and 5 days. Hospitalization or death was noted for the 180-day period. If pa.

Our goal was to identify the hemodynamic determinants of the mitral annulus MA ; diastolic velocities by tissue Doppler. BACKGROUND The MA diastolic velocities are promising indexes of left ventricular LV ; diastolic function. However, their hemodynamic determinants have not yet been evaluated. METHODS Ten adult mongrel dogs underwent left atrial LA ; and LV pressure measurements by Millar catheters while tissue Doppler was applied to record the MA diastolic velocities at the septal and lateral corners. Conventional transmitral flow was also obtained. Left atrial and LV pressures were modified utilizing fluid administration and caval occlusion, whereas dobutamine and esmolol were used to change LV and LA relaxation. Left ventricular filling pressures were altered during different lusitropic states to evaluate for the possible interaction of preload and LV relaxation on the early diastolic velocity Ea ; . RESULTS In the majority of dogs, a positive significant relation was observed between Ea and the transmitral pressure gradient r 0.57, p 0.04 ; . The Ea had strong correlations with tau r 0.83, p 0.001 ; , LV dP dt 0.8, p 0.001 ; and minimal LV pressure r 0.76, p 0.01 ; . However, there was no relation between Ea and the transmitral pressure gradient in experimental stages where tau 50 ms. Furthermore, the late diastolic velocity at both corners of the MA had significant positive relations with LA dP dt 0.67, p 0.01 ; and LA relaxation r 0.73, p 0.01 ; but an inverse correlation with LV end-diastolic pressure r 0.53, p 0.01 ; . CONCLUSIONS Left ventricular relaxation, minimal pressure and preload determine Ea while late diastolic velocity determinants include LA dP dt, LA relaxation and LV end-diastolic pressure.

We report the case of a patient admitted to the emergency room of our hospital with acute myocardial infarction in the inferior wall, who underwent primary angioplasty, complicated by shock that did not respond to the administration of catecholamines and intra-aortic counterpulsation balloon. The use of transesophageal echocardiography was crucial in showing systolic anterior motion of the mitral valve obstructing the left ventricular outflow tract. Dynamic obstruction of the left ventricular outflow tract with systolic anterior motion of the mitral valve has been reported in association with several conditions, such as hypertensive concentric hypertrophy1, excessive sympathetic stimulation2, 3, pericardial tamponade4, dobutamine stress tests5, postoperative mitral valvuloplasty6, and aortic valve replacement7, in addition to obstructive hypertrophic cardiomyopathy. Some cases of dynamic left ventricular outflow tract obstruction complicating anterior myocardial infarction have been reported8-12; however, no case of inferior myocardial infarction has been reported in association with that entity. The hemodynamic findings of myocardial infarction aggravated by left ventricular outflow tract obstruction have some implications in the treatment; these implications are not common in the treatment of the infarction without that complication. In the situation of hemodynamic deterioration, the use of intra-aortic counterpulsation balloon may have a deleterious effect on the patient diagnosed with that obstruction and may hinder improvement in clinical condition13, 14. The use of vasodilators and some catecholamines may also worsen the state of shock 14. We report the case of a patient with inferior myocardial infarction associated with left ventricular outflow tract obstruction aggravated by the use of intra-aortic counterpulsation balloon.

Process Chemicals showed excellent growth within the division. Volume expansion coupled with price improvements, led to broadbased growth in revenues. Clariant Oil Services enjoyed strong demand in all regions, especially North America. Functional fluids met with strong sales in Europe and in the heat transfer fluids as well as specialty solvents segments. This sales growth more than offsets the weakness in the deicing business caused by the mild winter. Increased raw material prices continued to affect Process Chemicals. All regions contributed to the excellent sales development, especially Asia and Latin America. The Mining Chemicals Business benefited from the continuing strong demand in iron ore in Latin America and doxorubicin.
