Arterial Perivascular Space‐Mediated Solute Transport in the Mouse Brain

Exploration, EarlyView.
The mechanisms underlying solute clearance from the brain parenchyma remain debated, with competing hypotheses involving bulk cerebrospinal fluid flow versus perivascular transport. Using multimodal in vivo imaging and computational modeling in mice, this study demonstrates that arterial pulsation drives bidirectional solute movement within the ...

Uterine artery Doppler flow velocimetry parameters for predicting gestational trophoblastic neoplasia after complete hydatidiform mole, a prospective cohort study

Clinics
OBJECTIVES: Doppler ultrasonography can be used to assess neoangiogenesis, a characteristic feature of postmolar gestational trophoblastic neoplasia. However, there is limited information on whether uterine artery Doppler flow velocimetry parameters can ...

Correlation of pulsatility index with intracranial pressure in traumatic brain injury [PDF]

Turkish Neurosurgery, 2010
In traumatic brain injury (TBI) patients, it is desired to monitor the intracranial pressure (ICP) to assess the cerebral haemodynamics and guide the therapy. The study was designed to see if the pulsatility index (PI) measured by transcranial Doppler ultrasonography (TCD) predicts information about ICP values.In 52 TBI patients with Glasgow Coma Scale

Vascular dysfunction in women with recurrent pregnancy loss: Possible association with antiphospholipid antibodies

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 206-214, April 2025.
Abstract Objective Antiphospholipid antibodies (aPL) are recognized to have a pivotal role in recurrent pregnancy loss (RPL) and cardiovascular disease. Therefore, we assessed the vascular function of women with RPL and examined the association with each type of aPL.

Predictors for intrapartum cesarean delivery after labor induction for suspected fetal growth restriction at term

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective In term pregnancies with suspected fetal growth restriction (FGR) undergoing induction of labor (IOL), predictors for intrapartum cesarean delivery (CD) remain unclear. We aimed to determine predictors for intrapartum CD in this population. Methods This study included a retrospective cohort of singleton pregnancies undergoing IOL at ≥

Transcranial Color‐Coded Duplex Sonography in Large‐Vessel Vasculitis Compatible With Takayasu Arteritis Presenting Intracranial Involvement and Vertebrobasilar Dolichoectasia: A Case Report

Journal of Clinical Ultrasound, EarlyView.
This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

Diagnostic Accuracy of Shear Wave Elastography for the Assessment of Congestive Liver Disease in Patients With Structural Heart Disease

Journal of Clinical Ultrasound, EarlyView.
Shear wave elastography demonstrated moderate diagnostic accuracy for detecting congestive liver disease in patients with structural heart disease. Increased liver stiffness was associated with echocardiographic markers of venous congestion, supporting the concept that elastography may serve as a noninvasive marker of cardiohepatic interaction ...
