Biomechanics of the cerebrum at finite strain : a tissue and cell level study/
The present study addresses the large strain nonlinear mechanical response of the cerebral cortex at the macroscopic tissue level and at the microscopic cell level. Unconfined uniaxial compression tests were conducted in vitro on cortical samples of porcine brains. The tests consisted of …

<strong>A Fractional Zener Constitutive Model to Describe the Degradation of Swine Cerebrum with Validation from Experimental Data and Predictions using Finite Element Analysis</strong>
… behavior.</p><p>A degradation study on swine cerebrum was performed using an <em>in vitro</em> unconfined compression test protocol at low strain rates to characterize how the tissue mechanical behavior varies with <em>postmortem</em> age and to illustrate the benefit of statistical analysis …

The Distribution of Histone Polypeptides and It's Methylated Basic Amino Acids from the Various Organs of the Rat
… histones were extracted from the cerebellum, cerebrum, liver, thymus and kidney of thirty 12 day old albino rats. Polyacrylamide gel electrophoresis of twenty-five μg of histone from the various organs was carried out. The F<sub>1</sub>, F<sub>3</sub>, F<sub>2a2</sub> plus F<sub>2b</sub> and …

Oviraptorosauria: Morphology, Phylogeny, and Endocranial Evolution
… that correspond closely to the olfactory bulbs, cerebrum, pituitary space, optic lobes, cerebellum, and brain stem. These partitions are then used to evaluate how these different regions of the "brain" are evolving. The division of the endocranial cast into partitions is a novel approach to …

Investigation of the functional effects of two novel ampakines in the CNS
… Org 24448 on functional activity in the murine cerebrum Following the establishment of the methodology, regional alterations in LCGU in response to the Ampakines Org 26576 and Org 24448 were investigated using [14C]-2-deoxyglucose autoradiography. Both Org 26576 and Org 24448 produced regionally …

ΜΕΛΕΤΗ ΤΗΣ ΟΨΙΜΗΣ ΜΕΤΑΓΕΝΝΗΤΙΚΗΣ ΑΝΑΠΤΥΞΕΩΣ ΤΟΥ ΚΡΑΝΙΟΥ
… A RATE OF GROWTH IDENTICAL WITH THAT OF THE CEREBRUM. THIS RATE IS CONSIDERABLY LOWER THAN THAT OF THE BODY AND LOWER THAN THE RATE OF VARIOUS OTHER TISSUES OF THE DEVELOPING BODY, DURING THE SAME PERIOD OF GROWTH.

Localization of Goα in the Developing and Adult Mouse Brain
… is found in various brain regions, including cerebrum, hippocampus, thalamus, and cerebellum. Although Go is already known to be present on both plasma- and endo-membranes, the precise subcellular location of Go protein has been a controversial issue because diverse detection methods such as …

Human brain lipid fatty acid composition in relation to infant diet
… and lignoceric acids when compared to the cerebrum. Analysis of the phospholipid and glycolipid composition of the cerebral and cerebellar white matter tissues was achieved by means of separation by high performance thin layer chromatography followed by scanning densitometry. The results of …

The neuropsychological investigation of dyslexic readers: an experimental approach to subtyping
… functioning of both the anterior and posterior cerebrum. Failure to be able to read has been hypothesized to be the result of dysfunction occurring anywhere throughout those functional units. In adults, anterior and posterior language problems have been established by assessing verbal fluency. …

Cloning and Characterization of the Vasopressin-Oxytocin Neuropeptide Signaling System in the Vocal Control System of the Zebra Finch (Taeniopygia guttata)
… in the hypothalamus and expressed in the cerebrum and pituitary gland of the brain. Studies of VP and OT have long demonstrated their influence on social behaviors in mammals. Comparative analyses of these neuropeptides and in-depth analyses in non-mammalian species may reveal the specific …

Evaluation of the Protective Capacity of Ice Hockey Goaltender Masks for Three Accident Events using Dynamic Response and Brain Stress and Strain
… strain (MPS) and von Mises stress in the cerebrum. The results demonstrated the importance of assessing the protective capacity of ice hockey goaltenders masks for each accident, as each event created a unique response. A comparison of unhelmeted and helmeted impacts revealed ice hockey …

Low grade gliomas treated at the University of Cape Town Academic Hospital complex: 2001-2017
… the cerebellum (27%), hypothalamus (17%) and cerebrum (14%). The most common histology was juvenile pilocytic astrocytoma (JPA) (n=62; 73%). Gross total resection (GTR) was achieved in 21 patients (24%). Twenty-four patients (27%) received chemotherapy of which 11 patients progressed. …

Carboxyl Methylation of Non-Histone Chromosomal Proteins
… Chromosomal proteins from the cerebellum, cerebrum, kidney, liver, and thymus contained significant amounts of <sup>3</sup>H-methyl groups. Turnover of the <sup>3</sup>H-methyl esters was extremely rapid when compared to the turnover rates of the NHCP. Interestingly, a methylesterase, was …
