(8) But to treat a mistake as an automatic disqualification for advancement – even as heinous a mistake as presiding over a botched operation that resulted in the killing of an innocent man – could be depriving organisations, and the country, of leaders who have been tested and will not make the same mistake again.
(9) A method using selective saturation pulses and gated spin-echo MRI automatically corrects for this motion and thus eliminates misregistration artifact from regional function analysis.

(14) From this, and previous studies indicating a dependency of contraction frequency on the inward verapamil-sensitive Na influx, it is suggested that the drugs modify the automaticity of this preparation by a primary influence on membrane Na exchange.
(15) Automatic analysis of oculopneumoplethysmography recordings might minimize the risks of misinterpretation and might improve the clinical significance of the Gee-oculopneumoplethysmography test.
(16) Global left ventricular ejection fraction (LVEF) was obtained by radionuclide angiography and analyzed with an automatic detection program.

(18) The algorithms involved are simple and a microprocessor-based automatic PCG analysis system using the proposed technique is being contemplated.
(19) Seventeen patients had type I complex partial seizures (CPS) with three consecutive phases: initial motionless staring, oral-alimentary automatisms, and reactive quasipurposeful movements during impaired consciousness.
(20) The case of a 32-year-old man who suffered a blow to his left supraorbital region and eyebrow in an automatic closing door is reported to draw attention to the uncommon but trivial nature of this injury which may result in profound visual loss.
(adv.) In a mechanical manner.
(1) Such a signal must be due to a small ferromagnetic crystal formed when the nerve is subjected to pressure, such as that due to mechanical injury.
(2) These data suggest that the hybrid is formed by the same mechanism in the absence and presence of the urea step.
(3) Some common eye movement deficits, and concepts such as 'the neural integrator' and the 'velocity storage mechanism', for which anatomical substrates are still sought, are introduced.
(4) We have investigated the effect of methimazole (MMI) on cell-mediated immunity and ascertained the mechanisms of immunosuppression produced by the drug.
(5) One hour after direct mechanical cardiomassage (DMCM) a moderately pronounced edema of the intercellular spaces in the basal compartment of the seminiferous epithelium, normal content of lactate and succinate dehydrogenases, and a certain decrease in the activity of glucose-6-phosphate dehydrogenases and NAD- and NADP-diaphorases were noted.
(6) It is concluded that amlodipine reduces myocardial ischemic injury by mechanism(s) that may involve a reduction in myocardial oxygen demand as well as by positively influencing transmembrane Ca2+ fluxes during ischemia and reperfusion.
(7) Models able to describe the events of cellular growth and division and the dynamics of cell populations are useful for the understanding of functional control mechanisms and for the theoretical support for automated analysis of flow cytometric data and of cell volume distributions.
(8) The following is a brief review of the history, mechanism of action, and potential adverse effects of neuromuscular blockers.
(9) However, the mechanism of the inhibitory action is still somewhat uncertain.
(10) It also provides mechanical support for the collateral ligaments during valgus or varus stress of the knee.
(11) We studied the hemodynamic changes caused by bronchoscopy under LA in mechanically ventilated patients and the effect of LA on the endoscopic decline in arterial pO2.
(12) Together these observations suggest that cytotactin is an endogenous cell surface modulatory protein and provide a possible mechanism whereby cytotactin may contribute to pattern formation during development, regeneration, tumorigenesis, and wound healing.
(13) Dilutional studies comparing the mechanism of inhibition of monoamine oxidase produced by Gerovital H3 and by ipronizid demonstrated that Gerovital H3 was a reversible inhibitor of monoamine oxidase.
(14) To investigate the mechanism of enhanced responsiveness of cholesterol-enriched human platelets, we compared stimulation by surface-membrane-receptor (thrombin) and post-receptor (AlF4-) G-protein-directed pathways.
(15) Based on our results, we propose the following hypotheses for the neurochemical mechanisms of motion sickness: (1) the histaminergic neuron system is involved in the signs and symptoms of motion sickness, including vomiting; (2) the acetylcholinergic neuron system is involved in the processes of habituation to motion sickness, including neural store mechanisms; and (3) the catecholaminergic neuron system in the brain stem is not related to the development of motion sickness.
(16) Thus, mechanical restitution of the ventricle is a dynamic process that can be assessed using an elastance-based approach in the in situ heart.
(17) The mechanism by which pertussis toxin (PT) breaks the unresponsiveness of delayed-type hypersensitivity (DTH) to sheep red blood cells (SRBC) was examined in B10 mice.
(18) This suggests that a physiological mechanism exists which can increase the barrier pressure to gastrooesophageal reflux during periods of active secretion of the stomach, as occurs in digestion.
(19) The macrophage-derived product, interleukin 1 (IL 1) is thought to play an important regulatory role in the proliferation of T lymphocytes; however, its mechanism of action is unknown.
(20) Adding a layer of private pensions, it was thought, does not involve Government mechanisms and keeps the money in the private sector.
