- The Open Access Proceedings Series for Conferences
The proceedings series Theoretical and Natural Science (TNS) is an
international
peer-reviewed open access series which publishes conference proceedings from a
wide variety of disciplinary perspectives concerning theoretical studies and
natural
science issues. The series publishes articles that are research-oriented and

Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by a gradual and irreversible decline in cognitive function. The underlying pathology involves the accumulation of amyloid beta, a protein implicated in the development and progression of the illness. Aducanumab is a type of human monoclonal antibody that exhibits preferential immunoreactivity towards both soluble and insoluble aggregates of Amyloid Beta (Aβ). Two phase 3 studies, namely EMERGE and ENGAGE, were conducted to evaluate the efficacy of aducanumab in individuals with early Alzheimer’s disease. These studies were designed identically, randomized, and double-blind in nature. Both trials were suspended early with the ineffective results shown in interim analysis for futility. Aducanumab was reassessed and met the primary and secondary clinical endpoints in EMERGE, but remains ineffective in ENGAGE. Reduction of Aβ plaques was observed in the high-dose group (10 mg/kg), showing a dose- and time-dependent pattern. The primary safety concern with Aducanumab is amyloid-related imaging abnormalities (ARIA), particularly in ApoEε4 carriers. Aducanumab is a new therapeutic strategy for AD, providing new treatment with disease-modifying potential. This paper evaluated the pharmacology, mechanism, clinical studies, and safety assessment of aducanumab. This research aims to provide a reference for the understanding of Aducanumab’s current research status and results.
This paper describes an experiment on Parkinson’s disease classification using multiple classification algorithms for comparison. Parkinson’s disease is a common neurological disorder, and early diagnosis and classification are important for the assessment of treatment and prognosis. Therefore, the research implications of this paper are clear. The classification algorithms used in the experiment include adaboost classification model, XGBoost classification model, logistic regression regression model, random forest plain Bayesian classification model, bp neural network and support vector machine. The experimental results show that adaboost classification model performs well when dealing with small sample data, XGBoost classification model performs well when dealing with large-scale datasets, and logistic regression regression model and random forest plain Bayesian classification model also have good performance. The bp neural network and support vector machine, on the other hand, perform poorly in terms of classification results and require a much larger dataset for support. These experimental results have important reference value for the classification and diagnosis of Parkinson’s disease. Different classification algorithms are suitable for different dataset sizes and characteristics, so in practical applications, we can choose different classification algorithms according to the size and characteristics of the dataset to achieve the optimal classification effect. In conclusion, the results of this paper provide a reference for the classification and diagnosis of Parkinson’s disease, as well as a guide for choosing appropriate classification algorithms. In the future, we can further expand the dataset size and use more classification algorithms for comparison to improve the accuracy and robustness of Parkinson’s disease classification.
ADC drugs, or antibody-drug conjugates, represent a class of specialized biopharmaceuticals employed in the treatment of neoplastic diseases and other specific medical conditions. ADCs are tailored therapeutics consisting of monoclonal antibodies covalently bonded to cytotoxic small-molecule payloads. These compounds gain entry into cancer cells by initiating endocytosis, ultimately deploying their intracellular cytotoxic agents to eliminate the malignancies. The theoretical advantage of such drugs is their ability to selectively target tumor tissue while sparing healthy cells. Since the introduction of the first ADC drug to the market in 2000, a surge of enthusiasm from diverse enterprises and research institutions has fueled the development and clinical evaluation of ADC drugs. Simultaneously, the field of ADC drug development has witnessed rapid advancements. This article aims to provide an overview of the fundamental structure and developmental evolution of ADC drugs, conduct a statistical analysis of ADC drugs currently in development, and explore potential future directions for the advancement of ADC drugs.
Aiming at the current problem of insufficient identification accuracy of coding regions in DNA sequences, this study proposes a protein coding region identification method based on IHHO-CNN-LSTM. Firstly, the data preprocessing of DNA sequences is transformed into feature vectors, and then the protein coding region identification model based on CNN-LSTM is established. To address the limitations of parameter selection of CNN-LSTM, a hybrid strategy improved Harris Hawk Optimization (HHO) algorithm is introduced to achieve adaptive parameter searching of CNN-LSTM, so as to obtain the optimization model of white matter coding region identification based on IHHO-CNN-LSTM. The improved model was used to accurately distinguish coding and non-coding regions. Two benchmark datasets, HMR195 and BG570, are selected for five-fold cross-validation, and the results show that the AUC values of the model designed in this paper are 0.9854 and 0.9895, the corresponding identification accuracy is 0.9527 and 0.9645, respectively, which are significantly better than other models, and also have a significant advantage in terms of computational efficiency. The proposed method can efficiently and accurately identify protein coding regions, which can help promote the related research in the field of genetic engineering.
