An Intact Kidney Slice Model to Investigate Vasa Recta Properties and Function in situ [PDF]

open access: yes, 2012
Background: Medullary blood flow is via vasa recta capillaries, which possess contractile pericytes. In vitro studies using isolated descending vasa recta show that pericytes can constrict/dilate descending vasa recta when vasoactive substances are ...

The multiple hit model of infantile and epileptic spasms: The 2025 update

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Infantile and epileptic spasms syndrome (IESS) is a developmental and epileptic encephalopathy manifesting with epileptic spasms and poor neurodevelopmental outcomes. There is an urgent need for the development of more effective and tolerated therapies.

New switching approach for DVR using one cycle control method

open access: yesAin Shams Engineering Journal, 2018
One of the effective devices to eliminate voltage disturbances of sensitive loads in distribution systems is dynamic voltage restorer (DVR). In previous studies, the sinusoidal pulse width modulation (SPWM) method has been used as a switching method for ...

Impact of cerebral blood flow and amyloid load on SUVR bias

open access: yesEJNMMI Research, 2022
Background Despite its widespread use, the semi-quantitative standardized uptake value ratio (SUVR) may be biased compared with the distribution volume ratio (DVR).

Efficient grid-based method in nonequilibrium Green's function calculations. Application to model atoms and molecules

open access: yes, 2009
We propose and apply the finite-element discrete variable representation to express the nonequilibrium Green's function for strongly inhomogeneous quantum systems.

In vivo PET quantification of the dopamine transporter in rat brain with [¹⁸F]LBT-999. [PDF]

open access: yes, 2013
INTRODUCTION: We examined whether [(18)F]LBT-999 ((E)-N-(4-fluorobut-2-enyl)2β-carbomethoxy-3β-(4'-tolyl)nortropane) is an efficient positron emission tomography (PET) tracer for the quantification of the dopamine transporter (DAT) in the healthy rat ...

Differential Progression of Neuroinflammation in Patients with Isolated Rapid‐Eye‐Movement Sleep Behavior Disorder

open access: yesMovement Disorders, EarlyView.
Abstract Background Neuroinflammation, measured using [11C](R)‐PK11195 positron emission tomography (PET), has been reported in isolated rapid‐eye‐movement sleep behavior disorder (iRBD), but its temporal progression is unknown. Objective The aim was to assess longitudinal progression of neuroinflammation in iRBD patients and its relationship with ...

Resonance dynamics of DCO ($\widetilde{X}\,{}^2A'$) simulated with the dynamically pruned discrete variable representation (DP-DVR)

open access: yes, 2018
Selected resonance states of the deuterated formyl radical in the electronic ground state ($\widetilde{X}\,{}^2A'$) are computed using our recently introduced dynamically pruned discrete variable representation (DP-DVR) [H. R. Larsson, B. Hartke and D. J.

Signatures of few-body resonances in finite volume [PDF]

open access: yes, 2018
We study systems of bosons and fermions in finite periodic boxes and show how the existence and properties of few-body resonances can be extracted from studying the volume dependence of the calculated energy spectra.

Influence of mix design method on the shear capacity of reinforced concrete beams made with high‐quality recycled coarse aggregate

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the shear capacity behavior of reinforced concrete (RC) beams without stirrups incorporating recycled coarse aggregate (RCA). An extensive database comprising 269 experimental data points from 40 journal articles published between 2001 and 2025 was compiled, excluding specimens with recycled fine aggregate or fiber ...
