Example Sentences:
(1) Gel filtration of the 40,000 rpm supernatant fraction of a homogenate of rat cerebral cortex on a Sepharose 6B column yielded two fractions: fraction II with the "Ca(2+) plus Mg(2+)-dependent" phosphodiesterase activity and fraction III containing its modulator.
(2) These findings may not indicate a redistribution of renal blood flow through resistance changes in specific parts of the renal vasculature but may represent the consequences of focal cortical ischaemia, most prominent in the outer cortex.
(3) The findings confirm and quantitate the severe atrophy of the neostriatum, in addition to demonstrating a severe loss of cerebral cortex and subcortical white matter in HD.
(4) The observation that phase reversals did not occur in area 29, together with the low incidence of phasic (rhythmic) theta-on cells, suggests that the posterior cingulate cortex does not independently generate type 2 theta.
(5) The use of functional test with the ACTH administration demonstrated organic affection of the CNS to sharply aggravate the weakening and even the exhaustion of the functional reserves of the glomerular and the reticular zones of the adrenal cortex developing during thyrotoxicosis, and also the reserve possibilities of the sympathico-adrenal system.
(6) In the kidneys the index of incorporation inthe epithelial cells of the renal cortex was 7.5-fold and in the brain cortex epithelium 15-fold as increased, respectively.
(7) Horizontal sections of the left cortex were reacted for the demonstration of HRP.
(8) A recent report suggested that neurons in the prefrontal, anterior cingulate, and primary motor cortex of the brains of schizophrenic subjects may be less dense than those in the brains of nonschizophrenic subjects.
(9) In this series there were 45 patients (40%) with independent focal interictal EEG epileptic abnormalities over frontobasal cortex (with or without independent spiking over interomedial temporal region).
(10) The corticotectal cells in the motor cortex differed from those in the premotor cortex in their size distribution; the former being small, the latter both small and large.
(11) In cases with unilateral hypoperfusion, the percentage of the activity in the lesion to that in the contralateral normal cortex on the early SPECT was correlated well with that on CBF measured by PET (r = 0.870, p less than 0.001).
(12) The pathway of ketogenesis in renal cortex must differ from that of the liver, as beta-hydroxy-beta-methylglutaryl-CoA synthetase is virtually absent from the kidney.
(13) Three animals received unilateral lesions which included both the inferior parietal lobule and a portion of adjacent dorsal prestriate cortex (IPL-PS).
(14) Total abolition of the CR ensued when the wave of CSD reached the motor (frontal) cortex and again was independent of the CS modality.
(15) After haemorrhage in conscious rabbits total renal blood flow fell by 25%, this fall being confined to the superficial renal cortex.
(16) Among the epileptic patients investigated by the stereotactic E. E. G. (Talairach) whose electrodes were introduced at or around the auditory cortex (Area 41, 42), the topography of the auditory responses by the electrical bipolar stimulation and that of the auditory evoked potential by the bilateral click sound stimulation were studied in relation to the ac--pc line (Talairach).
(17) Several types of neurons were differentiated on the basis of a study of neuronal activity in various parts of the cortex near the sulcus principalis during the execution of spatial delayed reactions by monkeys.
(18) However, at those times, autoradiographic images of the hippocampus and piriform cortex appeared distinctly different for [14C]2-deoxyglucose and [6(-14)C]glucose.
(19) Gonadectomy of females was accompanied by changes in the activity of individual HAS links in different direction--some reduction of ACTH in the hypophysis, a sharp and significant fall of the peripheral blood glucocorticoid level and a marked significant elevation of hydrococortisone production in the adrenal cortex in vitro.
(20) The alterations in DS frontal cortex included decreases in (n-6) and increases in (n-3) groups in choline and ethanolamine phosphoglycerides (CPG and EPG), as had previously been found in EPG and serine phosphoglyceride (SPG) of the DS fetal brain.
Oolite
Definition:
(n.) A variety of limestone, consisting of small round grains, resembling the roe of a fish. It sometimes constitutes extensive beds, as in the European Jurassic. See the Chart of Geology.
Example Sentences:
(1) I think, in all honestly, if I could be Bradley Whitford I would be very, very happy.” He becomes almost drawlingly dreamy, rolling his “r”s as he leans against the warm oolite cliffs of this Jurassic Coast, until rudely interrupted by me, asking whether there’s talk of a Broadchurch 3 .
