Study protocol: MRI-based assessment of cerebral blood flow under pharmacologically elevated blood pressure in patients under general anesthesia, and in sedated ICU patients with aneurysmal subarachnoid hemorrhage. [PDF]

open access: yesPLoS ONE
BackgroundMaintaining cerebral perfusion during anesthesia and intensive care is critical, yet the relationship between mean arterial pressure (MAP) and cerebral blood flow (CBF) remains poorly defined. In patients with aneurysmal subarachnoid hemorrhage

Agreement between arterial blood pressures measured non-invasively and invasively in anaesthetised sheep [PDF]

open access: yesActa Veterinaria Scandinavica
Background Both invasive and non-invasive blood pressure measuring methods are used in clinical and experimental work in veterinary medicine and several studies validating these methods are published.

Cardinal invariants and special maps of quasicontinuous functions with the topology of pointwise convergence

open access: yesApplied General Topology, 2022
For topological spaces X and Y, let Qp(X,Y) be the space of all quasicontinuous functions from X to Y with the topology of pointwise convergence.

Dynamical property of hyperspace on uniform space

open access: yesDemonstratio Mathematica, 2023
First, we introduce the concepts of equicontinuity, expansivity , ergodic shadowing property, and chain transitivity in uniform space. Second, we study the dynamical properties of equicontinuity, expansivity , ergodic shadowing property, and chain ...

Inducing Maps Between Gromov Boundaries [PDF]

open access: yesMediterranean Journal of Mathematics, 2015
It is well known that quasi-isometric embeddings of Gromov hyperbolic spaces induce topological embeddings of their Gromov boundaries. A more general question is to detect classes of functions between Gromov hyperbolic spaces that induce continuous maps between their Gromov boundaries.

Dynamic properties of the dynamical system SFnm(X), SFnm(f))

open access: yesApplied General Topology, 2020
Let X be a continuum and let n be a positive integer. We consider the hyperspaces Fn(X) and SFn(X). If m is an integer such that n > m ≥ 1, we consider the quotient space SFnm(X). For a given map f : X → X, we consider the induced maps Fn(f) : Fn(X) → Fn(

Saturation-Induced Phase Error Compensation Method Using Complementary Phase

open access: yesMicromachines, 2023
Intensity saturation can induce phase error and, thus, measurement error in fringe projection profilometry. To reduce saturation-induced phase errors, a compensation method is developed.

TPA‐induced activation of MAP kinase [PDF]

open access: yesFEBS Letters, 1991
Threonine and tyrosine residue phosphorylation of a 42 kDa protein identified as mitogen‐activated protein kinase (MAP kinase) was stimulated in extracts from TPA‐pretreated cells. It is further shown that TPA pretreatment leads to the enhancement of an activity that will induce reactivation of dephosphorylated/inactivated MAP kinase.

Inhibitory neuron map of sevoflurane induced neurotoxicity model in young primates

open access: yesFrontiers in Cellular Neuroscience, 2023
IntroductionSevoflurane, one of the most commonly used anesthetic agents in children, may induce neuronal dysfunction and cognitive impairment. Exposure to sevoflurane might induce an imbalance between neural excitation and inhibition which could be a ...

Induced dynamics on the hyperspaces

open access: yesApplied General Topology, 2016
In this paper, we study the dynamics induced by finite commutative relation on the hyperspaces. We prove that the dynamics induced on the hyperspace by a non-trivial commutative family of continuous self maps cannot be transitive and hence cannot exhibit
