	1	Characterization of cerebral blood flow dynamics with multiscale entropy显示文摘Based on the laser speckle contrast imaging(LSCI)and the multiscale entropy(MSE),we study in this work the blood flow dynamics at the levels of cerebral veins and the surrounding network of microcerebral vessels.We discuss how the phenylephrine-related acute peripheral bypertension is refected in the cerebral circulation and show that the observed changes are scale dependent,and they are signifcantly more pronounced in microcerebral vessels,while the macrocerebral dynamics does not demonstrate authentic inter-group distinctions.We also consider the permeability of blood-brain barrier(BBB)and study its opening caused by sound exposure.We show that alterations associated with the BBB opening can be revealed by the analysis of blood flow at the level of macrocerebral vessels.

	2	WAVELET-BASED ANALYSIS OF CEREBROVASCULAR DYNAMICS IN NEWBORN RATS WITH INTRACRANIAL HEMORRHAGES显示文摘Intracranial hemorrhage(I)is a major problem of neonatal intensive care.The incidence of Iistypically asymptomatic and'canmot be effectively detected by standard diagnostic methods.The mechanisms underlying IH are unknown but there is evidence that stress-induced disorders inadrenergic regulation of cerebral venous blood flow (CVBF) are among the main reasons.Quantitative and qualitative:could significantly advance understanding ofthe nature of I in newbornslth1sions of CVBF in newborn rats withan experimental model of stinjection.Our analysis is bas ed on theDoppler optical coheavelet-based approachthat provides sensitiv external factors.Theobtained resultsccompanied by asupprectivity to adrenaline.Weintroducd show that the values0<1.23 estimated ithelodinto the sympathicusindicate abnormal reactions associated with the developent of I.We conclude that t he revealed areactivity of the cerebral veins to adrenaline represents a possible mechanism responsible forpat hological changes in CVBF.

	3	Hidden stage of intracranial hemorrhage in newborn rats studied with laser speckle contrast imaging and wavelets显示文摘Using the laser speckle contrast imaging and wavelet-based analyses,we investigate a latent('hidden')stage of the development of intracranial hemorrhages(ICHs)in newborn rats.We apply two measures based on the continuous wavelet-transform of blood flow velocity in the sagittal sinus,namely,the spectral energy in distinct frequency ranges and a multiscality degree characterizing complexity of experimental data.We show that the wavelet-based multifractal formalism reveals changes in the cerebrovascular blood flow at the development of ICH.
