Evaluation of in vitro toxicity of common phytochemicals included in weight loss supplements using 1H NMR spectroscopy

open access: yesFEBS Open Bio, EarlyView.
We investigated the toxicity of 12 active compounds commonly found in herbal weight loss supplements (WLS) using human liver and colon cell models. Epigallocatechin‐3‐gallate was the only compound showing significant toxicity. Metabolic profiling revealed protein degradation, disrupted energy and lipid metabolism suggesting that the inclusion of EGCG ...

A Novel Classification Method for a Driver’s Cognitive Stress Level by Transferring Interbeat Intervals of the ECG Signal to Pictures

open access: yesSensors, 2020
In this study, a novel classification method for a driver’s cognitive stress level was proposed, whereby the interbeat intervals extracted from an electrocardiogram (ECG) signal were transferred to pictures, and a convolution neural network (CNN ...

Global Priorities for Vehicle Safety [PDF]

open access: yesTraffic Injury Prevention, 2003
Presently, just over 1 million people die annually in road crashes; that number will rise to 2 million by 2020. 85% of these fatal crashes occur in developing countries, and of those, about 75% involve pedestrians, bicyclists, and motorcyclists. Over the past 10 years several organizations have attempted to outline the nature and severity of these ...
