Suction conditions for minimizing the production of free hemoglobin during blood salvage using an autotransfusion apparatus [PDF]

open access: yesKorean Journal of Anesthesiology, 2011
BackgroundThree kinds of conditions should be considered to reduce free hemoglobin production using an autologous cell salvage device. They are the negative suction pressure, the size of suction tip, and the air contact during suction. We want to examine

Claiming trend in toxicological and pharmacological dose-response studies: an overview on statistical methods and related R-Software [PDF]

open access: yesarXiv, 2020
There are very different statistical methods for demonstrating a trend in pharmacological experiments. Here, the focus is on sparse models with only one parameter to be estimated and interpreted: the increase in the regression model and the difference to control in the contrast model.

Evaluation of histological findings with severity grade, to analyze toxicology in-vivo studies [PDF]

open access: yesarXiv, 2022
In-vivo toxicological studies are characterized by multiple primary endpoints with quite different scales. Whereas guidelines and publications provide various statistical tests for normally distributed endpoints (such as organ weights) and proportions (such as tumor rates), few approaches are available for graded histopathological findings, such as 0, +

A Machine Learning Model to Predict Drug Transfer Across the Human Placenta Barrier

open access: yesFrontiers in Chemistry, 2021
The development of computational models for assessing the transfer of chemicals across the placental membrane would be of the utmost importance in drug discovery campaigns, in order to develop safe therapeutic options. We have developed a low-dimensional

Benchmarking Toxic Molecule Classification using Graph Neural Networks and Few Shot Learning [PDF]

open access: yesarXiv, 2023
Traditional methods like Graph Convolutional Networks (GCNs) face challenges with limited data and class imbalance, leading to suboptimal performance in graph classification tasks during toxicity prediction of molecules as a whole. To address these issues, we harness the power of Graph Isomorphic Networks, Multi Headed Attention and Free Large-scale ...
