Activation of rat pituitary-adrenocortical and sympatho-adrenomedullary system in response to different stressors
(Neuroendocrinology Letters, 2005)
OBJECTIVE: The effects of three different long-term (21 days) stresses: isolation (LTI), forced swimming (LTS) and isolation accompanied by forced swimming (LTI+LTS) on the level of plasma noradrenaline (NA), adrenaline ...
Crystallinity changes and melting behavior of the uniaxially oriented iPP exposed to high doses of gamma radiation
(Polymer Degradation and Stability, 2005)
Samples of isotactic polypropylene (iPP) oriented via solid-state stretching at elevated temperature (draw ratios of 1, 3, 5, 7.5, 10, 12.5 and 15) were analyzed. Gel content measurements, wide-angle X-ray diffraction ...
Brain glucocorticoid receptor and heat shock protein 70 levels in rats exposed to acute, chronic or combined stress
(Neuropsychobiology, 2005)
The pattern and intensity of glucocorticoid receptor (GR) and heat shock 70 protein (Hsp 70) changes in the hippocampus and brain cortex of adult Wistar rat males exposed to acute (immobilization, cold) and chronic (social ...
Dynamics of bright discrete staggered solitons in photovoltaic photorefractive media
(European Physical Journal B. Condensed Matter and Complex Systems, 2005)
Theoretical results on spatial optical bright solitons excited in arrays of nonlinear defocusing waveguides, that result from the photovoltaic effect in a photorefractive material, are presented. The existence of four types ...
AT1 receptor A1166C and AT2 receptor-1332A/G gene polymorphisms: Efficient genotyping by single-tube PCR
(Journal of Clinical Laboratory Analysis, 2005)
Angiotensin II type 1 receptor (AT1) and angiotensin II type 2 receptor (AT2) genes have been investigated in recent years as potential etiologic candidates for cardiovascular and renal diseases. The pathogenic implications ...
Hot pressing of Y2O3 doped Si3N4 ceramics
(Materials Science Forum, 2005)
The effect of seeding on the microstructure and mechanical properties of hot-pressed silicon nitride was investigated by introducing large, elongated beta-Si3N4 particles into an alpha-Si3N4 matrix. Densification and ...
Novel stressors affected catecholamine stores in socially isolated normotensive and spontaneously hypertensive rats
(Autonomic Neuroscience: Basic and Clinical, 2005)
Catecholamines in some central (hypothalamus and hippocampus) and peripheral tissues (adrenal glands and heart auricles) of long-term socially isolated normotensive and spontaneously hypertensive rats exposed to novel ...
Raman spectroscopy of Cd1-xMnxS quantum dots
(Journal of Physics. D: Applied Physics, 2005)
Powders consisting of 44 angstrom Cd1-xMnxS (x = 0; 0.05; 0.1; 0.15; 0.3) quantum dots (QDs) were synthesized using the colloidal chemistry method and characterized by Raman scattering measurements. The dominant Raman line ...
Kobayashi-Kondo-Maskawa-t Hooft interaction in pentaquarks
(Physical Review D, 2005)
We review critically the predictions of pentaquarks in the quark model, in particular, those based on the flavor-spin-dependent (Glozman-Riska) hyperfine interaction and the color-spin (one-gluon-exchange Fermi-Breit) one. ...
Kondo insulator description of spin state transition in FeSb2
(Physical Review B: Condensed Matter and Materials Physics, 2005)
The thermal expansion and heat capacity of FeSb2 at ambient pressure agrees with a picture of a temperature induced spin state transition within the Fe t(2g) multiplet. However, high pressure powder diffraction data show ...
