(11) 2 (9%) operative death were in the SSR and 7 (33%) in the APER.
(12) In 20 patients with temporal lobe lesions and 10 controls, the averaged photic-evoked responses (APERs) and their dispersion pattern (DP) were investigated in inion-vertex-lead and bilaterally in inion-parietal leads (I-P3 and I-P4).
(13) One hundred (68 per cent) underwent SSR, 33 (22 per cent) had an APER and 16 (10 per cent) had a local procedure.
(14) In the APER group, the local recurrence rate was 45.5%, occurring in 5 of 11 cases; and in the SSR group 46.1%, occurring in 6 of 13 cases, with no significant difference between the two groups.
(15) The incidence of recurrence after radical SSR (n = 74) was compared with the historical control group which underwent radical APER, the two groups being matched for Dukes' stage and height of the lesion.
(16) The appearance of an ample late negative deflection (N3) followed by a deep positive one (P3) of APER and of an atypical DP in tired subjects, neurotics and in patients with neurotic syndromes, may be considered signs of tiredness and of attention lability.
(17) The commonest form of treatment during the study period was an abdomino-perineal excision of rectum (APER).
(18) Temperature-shift experiments indicated that the temperature-sensitive-period of the aper CTF36 mutation occurs around Days 2-4 after eclosion.
(19) We have therefore compared our results of SSR for low and mid-rectal cancers performed between 1978 and mid 1982 with those obtained with APER before this period.
(20) The role of the temporal lobe in the organization of APER in visual areas is discussed.
Apex
Definition:
(n.) The tip, top, point, or angular summit of anything; as, the apex of a mountain, spire, or cone; the apex, or tip, of a leaf.
(n.) The end or edge of a vein nearest the surface.
Example Sentences:
(1) After 1 year, anesthesia was induced with chloralose and an electrode catheter placed at the right ventricular apex.
(2) Following injections of HRP into the apex of the heart, the sinoatrial (SA) nodal region and the ventral wall of the right ventricle, we observed that HRP-labeled sympathetic neurons were localized predominantly in the right stellate ganglia, and to a lesser extent, in the right superior and middle cervical ganglia, and left stellate ganglia.
(3) It is therefore suggested that salt water adaptation triggers a cellular reorganization of the epithelium in such a way that leaky junctions (a low resistance pathway) appear at the apex of the chloride cells.
(4) When HRP was injected in the left ventricular wall or the apex, few labeled neurons were identified in the DMN.
(5) The length of the diaphragmatic wall of the heart in both the right and left ventricle was equal to the sum of the length of the inflow tract and the thickness of the ventricular wall at the apex.
(6) However, the external muscle fibers of the ventricles ran clockwise from base to apex toward the center of the vortex, which had a striking resemblance to the normal rather than the mirror image pattern.
(7) In the RAO view with the collimator flat against the chest there was better resolution of the cardiac apex.
(8) Their proliferating regions are located in the apex tip, where the various cells originate.
(9) In these tissues, the viral DNA replicated at the site of inoculation and was transported first to the roots, then to the shoot apex and to the neighboring leaves and the flowers.
(10) The vertical distances were compared with measurements taken from periapical radiographs between the apex of each mesial root and the superior border of the mandibular canal prior to sectioning.
(11) Three of six patients in whom treatment failed had disease at the vaginal apex.
(12) We recommend this skin incision for young patients with pneumothorax if the chest CT scan confirms that the bullae or blebs are localized to the apex of superior segment of the lower lobe.
(13) MRI only offered advantages over CT in lesions of the orbital apex, the upper part of the orbit, and in the diagnosis of inflammatory processes.
(14) In the accelerated protocol, one, two, and then three extrastimuli were introduced at each of three basic drive train cycle lengths (350, 400, and 600 msec) at the right ventricular apex; the procedure was repeated at a second right ventricular site.
(15) Magnetic resonance imaging of the chest in patients with lung cancer is being investigated, but current studies comparing it with CT demonstrate no definite advantage at this time, with the possible exception of the lung apex in which T1 weighted thin-section coronal views are useful.
(16) The apex to base lung distribution of 99Tcm-C and 81Krm appeared to be similar.
(17) If a web has a low apex angle and the skin is elastic, the length-width ratio may be as great as 1.5:1.
