RR interval-respiratory signal waveform modeling in human slow paced and spontaneous breathing
(Respiratory Physiology and Neurobiology, 2014)
Our aim was to model the dependence of respiratory sinus arrhythmia (RSA) on the respiratory waveform and to elucidate underlying mechanisms of cardiorespiratory coupling. In 30 subjects, RR interval and respiratory signal ...
Validation of Minor Actinides Fission Neutron Cross-Sections
(Nuclear technology and radiation protection, 2015)
Verification of neutron fission cross-sections of minor actinides from some recently available evaluated nuclear data libraries was carried out by comparison of the reaction rates calculated by the MCNP6.1 computer code ...
Precipitation of radiation belt electrons by magnetospherically reflected whistlers
(Journal of Geophysical Research - Space Physics, 1998)
We use a test particle simulation model based on gyro-averaged equations of motion to study the influence of oblique magnetospherically reflected (MR) whistlers on the near-loss-cone distribution function of radiation belt ...
Nonlinear localized flat-band modes with spin-orbit coupling
(Physical Review B: Condensed Matter and Materials Physics, 2016)
We report the coexistence and properties of stable compact localized states (CLSs) and discrete solitons (DSs) for nonlinear spinor waves on a flat-band network with spin-orbit coupling (SOC). The system can be implemented ...
Nonlinear properties of cardiac rhythm and respiratory signal under paced breathing in young and middle-aged healthy subjects
(Medical Engineering and Physics, 2014)
We examined the effects of gender and age in young and middle-aged subjects on the level of cardiorespiratory interaction by analyzing properties of cardiac, respiratory and cardiac-respiratory regulatory mechanisms under ...
Synthesis and Characterization of Core-Shell Magnetic Mesoporous Silica and Organosilica Nanostructures
(MRS Advances, 2017)
Initial results en route toward construction of complex magnetic core-shell silica and organosilica nanotheranostics are presented. Magnetite nanoparticles are synthesized by three different methods and embedded within ...
Effect of Age and Allele Variants of CYP3A5, CYP3A4, and POR Genes on the Pharmacokinetics of Cyclosporin A in Pediatric Renal Transplant Recipients From Serbia
(Therapeutic Drug Monitoring, 2017)
Background: The interindividual variability of cyclosporin A (CsA) pharmacokinetics might be explained by heterogeneity in the cytochrome P450 3A (CYP3A) subfamily. Altered CYP3A enzyme activity was associated with variant ...
Patient Doses in Computed Tomography: An Assessment of Local Diagnostic Reference Levels in a Large Teaching Hospital
(Nuclear technology and radiation protection, 2012)
This paper presents an estimation of local diagnostic reference levels in computed tomography in a large teaching hospital. Local diagnostic reference levels, expressed in terms of volume weighted computed tomography dose ...
The role of G protein coupled receptor kinases in neurocardiovascular pathophysiology
(Archives of Medical Science, 2012)
In coronary artery disease the G protein related kinases (GRKs) play a role in desensitization of beta-adrenoreceptors (AR) after coronary occlusion. Targeted deletion and lowering of cardiac myocyte GRK-2 decreases the ...
Build-Up PMMA Plate Effect on Calibration of TLD Reader
(RAD Conference Proceedings, 2015)
The routine monitoring of the occupationally exposed individuals constitutes an integral part of radiation protection program implemented at the Vinca Institute of Nuclear Sciences (INNV). The Individual monitoring service ...
