Segmentation of Drug-Treated Cell Image and Mitochondrial-Oxidative Stress Using Deep Convolutional Neural Network

Abstract

Most multicellular organisms require apoptosis, or programmed cell death, to function properly and survive. On the other hand, morphological and biochemical characteristics of apoptosis have remained remarkably consistent throughout evolution. Apoptosis is thought to have at least three functionally distinct phases: induction, effector, and execution. Recent studies have revealed that reactive oxygen species (ROS) and the oxidative stress could play an essential role in apoptosis. Advanced microscopic imaging techniques allow biologists to acquire an extensive amount of cell images within a matter of minutes which rule out the manual analysis of image data acquisition. The segmentation of cell images is often considered the cornerstone and central problem for image analysis. Currently, the issue of segmentation of mitochondrial cell images via deep learning receives increasing attention. The manual labeling of cell images is time-consuming and challenging to train a pro. As a courtesy method, mitochondrial cell imaging (MCI) is proposed to identify the normal, drug-treated, and diseased cells. Furthermore, cell movement (fission and fusion) is measured to evaluate disease risk. The newly proposed drug-treated, normal, and diseased image segmentation (DNDIS) algorithm can quickly segment mitochondrial cell images without supervision and further segment the highly drug-treated cells in the picture, i.e., normal, diseased, and drug-treated cells. The proposed method is based on the ResNet-50 deep learning algorithm. The dataset consists of 414 images mainly categorised into different sets (drug, diseased, and normal) used microscopically. The proposed automated segmentation method has outperformed and secured high precision (90%, 92%, and 94%); moreover, it also achieves proper training. This study will benefit medicines and diseased cell measurements in medical tests and clinical practices.

Wearable Flexible Electronics Based Cardiac Electrode for Researcher Mental Stress Detection System Using Machine Learning Models on Single Lead Electrocardiogram Signal

“…In addition, we also classify the inter-subject classification using the DT classifier based on the leave one out model. We obtained some performance measures such as recall, specificity, precision, accuracy, F1, and Area Under the Curve (AUC) [ 42 , 43 , 78 , 79 ]. The standard performance measures are described in Equations (1)–(5).…”

Ensemble Computational Intelligent for Insomnia Sleep Stage Detection via the Sleep ECG Signal

“…Demir et al [35] used ECG signals for the detection of person based on the ECG signals. Salari et.al [56] illustrate about the sleep apnea disorder in which different machine and deep learning approaches have been used to detect the disorder. The RNN approach found to be more efficient as compared to SA and CNN.…”

An End-to-End Cardiac Arrhythmia Recognition Method with an Effective DenseNet Model on Imbalanced Datasets Using ECG Signal

“…where D represents the training samples, and C narrates the class numbers. As for the example, if t j holds the class i, t ji � 1 and p ji will be the predicted probability; otherwise, t ji � 0. e performance of our proposed method is evaluated with four metrics: precision, recall, F 1-score , and accuracy, which are expressed in (2) to (5) [54][55][56], where TP, FP, TN, and FN are the true positive, false positive, true negative, and false negative, respectively. TP represents the beat recognition result in which positive is represented as positive, whereas FN represents the result in which positive is represented as negative.…”
