(18) The factors which impeded good recovery were primary brain damage due to preceding diseases such as cerebral infarct or hemorrhage, initial head injury, parkinsonism, and postoperative psychiatric disturbances.
(19) No protection from stimulation-associated impedance modifications was provided by the systemic administration of a material of high osmolarity (Mannitol) but the usual impedance decrease was not seen after systemic administration of a glucocorticoid.
(20) Twenty preterm infants ventilated for the respiratory distress syndrome were studied on 44 occasions to identify the pattern of interaction between their spontaneous respiratory efforts and the ventilator, using three techniques: (1) an oesophageal balloon and pneumotachograph, (2) impedance respirography and (3) clinical scoring.
Preclude
Definition:
(v.) To put a barrier before; hence, to shut out; to hinder; to stop; to impede.
(v.) To shut out by anticipative action; to prevent or hinder by necessary consequence or implication; to deter action of, access to, employment of, etc.; to render ineffectual; to obviate by anticipation.
Example Sentences:
(1) However, the variation in samples, even from among individual animals that had survived challenge, was so great that it precludes the use of the macrophage migration technique as a routine standard assay procedure for immunity.
(2) However, hemodynamic effects of the compound, suggesting an oxygen sparing action, did not preclude the antifibrillatory effectiveness.
(3) Since group therapy and sensory stimulation over a relatively short period can result in clinical and testable improvement, the diagnosis of "chronic brain syndrome" in the elderly should not be allowed to preclude the provision of appropriate psychiatric therapy.
(4) Positive biopsy findings may preclude transplantation.
(5) These findings may preclude the use of controlled studies on early synovectomy using the non-operated hand as a control in a long-term assessment of X-ray progression.
(6) Immunoassay of semen samples for CTX were not diagnostic, but the sensitivity and timing of the test employed may have precluded detection of small quantities of the toxin.
(7) These were all mild or moderate in severity and did not preclude continued administration of the study drug.
(8) Moreover, reexamination of the original X-ray maps reported in 1968 and thought to preclude a Tyr-248-Zn interaction now leads to the conclusion that in up to 25 per cent of the molecules in the crystals ttyr-248 interacts with the active site zinc atom (W.D.
(9) Nowadays, conventional cholecystectomy remains indicated when laparoscopy is contra-indicated, notably in cases with tight peritoneal adhesions precluding laparoscopy.
(10) However, this does not preclude the need for appropriately ex vivo-handled specimens for monitoring isepamicin concentrations in plasma to ensure therapeutic efficacy and prevent toxicity.
