Metformin alleviates bevacizumab-induced vascular endothelial injury in mice through growth differentiation factor 15 upregulation [PDF]

Iranian Journal of Basic Medical Sciences
Objective(s): Bevacizumab is a commonly used anticancer drug in clinical practice, but it often leads to adverse reactions such as vascular endothelial damage, hypertension, arterial and venous thrombosis, and bleeding.

Concomitant Gradient Effects Across Field Strengths and Gradient Amplitudes: Improved Estimation of Errors and Correction of Concomitant Dephasing and Diffusion Weighting

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Deleterious effects from concomitant gradients are amplified at lower field strengths and stronger gradients. We aimed to show the signal errors caused by concomitant gradients across a wide range of hardware configurations and propose corrections that can be applied during experimental design and analysis.

Continuous monitoring of free fatty acid release from adipocytes by pH-stat titration.

Journal of Lipid Research, 1979
A methods for direct and continuous monitoring of free fatty acid release in adipocyte suspensions is described. Using a pH-stat apparatus the protons from the released free fatty acids are continuously titrated and the accumulated amount of OH- added is

Fast iterative methods for symmetric sinc-Galerkin systems

, 1999
The symmetric sinc-Galerkin method developed by Lund, when applied to the second-order self-adjoint boundary value problem, gives rise to a symmetric coefficient matrix. The coefficient matrix has a special structure so that it can be advantageously used

Transverse Relaxation Time Constant of Cystathionine in Human Glioma at 3 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Cystathionine (Cth) has emerged as a promising biomarker for identifying 1p/19q codeleted gliomas. However, little is known about the T2 relaxation time constant of Cth in gliomas. The aim of this study was to measure the T2 of Cth in vivo in glioma and compare it to the T2s of other metabolites at 3 T.

Solution of a Volterra integral equation by the Sinc-collocation method

Journal of Computational and Applied Mathematics, 2007
The authors investigate the following problems: (1) a collocation procedure for a linear Volterra integral equation of the second kind and (2) its approximate solutions using the sinc basis functions based on the conformal maps of analytic functions.

Ventilation Imaging of the Lung at 0.55T With Continuous Slice Cycling

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To propose and evaluate a novel method for pulmonary ventilation imaging, offering considerably improved SNR. Methods A continuous slice cycling (CSC) acquisition scheme is proposed to exclusively capture signal modulations from respiratory motion with increased SNR.

Variable Doppler Starting Point Keystone Transform for Radar Maneuvering Target Detection

Remote Sensing
The Doppler band compensated by the keystone transform (KT) is limited. Therefore, it needs to be used in conjunction with the Doppler ambiguity compensation function to correct the range migration (RM) caused by maneuvering targets with Doppler ...

A Modified Balanced Steady State Free Precession Sequence for Overhauser Magnetic Resonance Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Low‐ and ultralow‐field magnetic resonance imaging (ULF MRI) have inherently low signal‐to‐noise ratio (SNR) by design. Overhauser dynamic nuclear polarization (ODNP) stands out as an effective solution for continuous signal enhancement.
