Challenges in medication titration in children with heart failure [PDF]

open access: yesJHLT Open
The management of pediatric heart failure and titration of oral medical therapies remains in its infancy. Burdened by a lack of understanding of the diverse pediatric heart failure etiologies, limitations in clinical trials, a lack of society guidelines,

The computerized determination of double-layer capacitance with the use of kalousek-type waveforms and its application in titrimetry [PDF]

open access: yes, 1980
A method for the rapid determination of double-layer capacitance—potential curves of electrodes is described. An on-line computer is used to apply Kalousek-type waveforms to the electrochemical cell and to measure the accompanying current response.

A New Trial to Measure ABO Antibodies Using Complement-Dependent Cytotoxicity

open access: yesMedicina, 2022
Background and objectives: The ABO antibody (Ab) titration tests are used in monitoring in ABO-incompatible (ABOi) solid organ transplantation (SOT). However, currently developed ABO Ab tests show Ab binding reactions. This study attempted to measure ABO

Use of the pK Spectroscopy Method in the Study of Protolytic Properties of Humic Substances and Other Soil Polyelectrolytes

open access: yesAgronomy, 2021
A common technique for the potentiometric analysis of complex protolytic systems is mathematical data processing. This approach allows for transforming the experimental titration curve into a function of the ionogenic group distribution of the titrated ...

Comparison of Analytical Methods for Determining Methylesterification and Acetylation of Pectin

open access: yesApplied Sciences, 2021
The esterification of galacturonic acid with methanol and/or acetic acid is important for the structural analysis of pectin. Although several methods have been reported for determining the degree of methylesterification (DM) and acetylation (DAc), the ...

Evaluation of the Apnea-Hypopnea Index Determined by Adaptive Servo-Ventilation Devices in Patients With Heart Failure and Sleep-Disordered Breathing

open access: yesFrontiers in Cardiovascular Medicine, 2021
Introduction: Adaptive servo-ventilation (ASV) devices are designed to suppress central respiratory events, and therefore effective for sleep-disordered breathing (SDB) in patients with heart failure (HF) and provide information about their residual ...
