Summary: Drug repositioning is a method to discover new therapeutic uses of existing drugs. This study proposed a novel model to identify drug-disease associations by building drug networks, disease networks, and generating features using the Mashup algorithm, and then building the model with the random forest classification algorithm. The model showed good performance with some tests indicating optimal dimensions of drug and disease features for construction.

Summary: Cluster algorithms are increasingly used in biomedical research, but there is no established method for calculating a priori statistical power in cluster analysis. Through simulation experiments, we found that clustering outcomes are mainly influenced by large effect sizes or the accumulation of many smaller effects, while differences in covariance structure have little impact. Sufficient statistical power can be achieved with relatively small samples (N = 20 per subgroup) as long as cluster separation is large. Additionally, we demonstrated that fuzzy clustering provides a more parsimonious and powerful alternative for identifying separable multivariate normal distributions.

Summary: This study proposes a deep learning model based on a recurrent neural network (RNN) for predicting histone lysine crotonylation (Kcr) sites in proteins. By embedding the peptide sequences, the efficiency of RNN-based models like LSTM, BiLSTM, and BiGRU networks is investigated. The comparison with other tools and cross-validation tests demonstrate the outstanding performance and computational efficiency of the BiGRU model. A webserver called Sohoko-Kcr is deployed for free use based on the proposed model.

Summary: High-throughput next-generation sequencing allows for the generation of large amounts of multi-omics data, which has revolutionized biomedical research by providing a more comprehensive understanding of biological systems and disease development mechanisms. Deep learning algorithms have emerged as a promising method in multi-omics data analysis due to their predictive performance and ability to capture nonlinear and hierarchical features. However, integrating and translating multi-omics data into functional insights remains a challenge, but there is a clear trend towards incorporating multi-omics analysis in biomedical research to explain complex relationships between molecular layers.

Summary: This systematic review evaluates the test accuracy of RT-LAMP and RT-PCR for diagnosing COVID-19. The overall sensitivity of RT-PCR and RT-LAMP was found to be 0.96 and 0.92, respectively, with false-negative rates of 0.06 and 0.12. Subgroup analysis suggests that mixed sampling and multiple target gene diagnosis methods have better diagnostic value. The study shows that RT-PCR and RT-LAMP have high value in diagnosing COVID-19, but there is still a false-negative rate of about 6%-12%.

Summary: The COVID-19 pandemic has posed an unprecedented threat to global public health and economies. Scaling up testing for rapid diagnosis of infected patients and quarantine measures are crucial strategies to curb the spread of the virus. Establishing globally accessible diagnostic tests is important for understanding the epidemiology. Recent efforts have focused on utilizing LAMP-based isothermal detection and minimizing reagent requirements to overcome limitations of current tests. Incorporating CRISPR technology with isothermal amplification shows promise for sensitive and rapid detection of SARS-CoV-2 nucleic acids, potentially transforming diagnostics and epidemiology.

The model, called DeepDDS, achieved better performance than other methods in predicting drug synergy. Additionally, we explored the interpretability of the model and found important chemical substructures of drugs. DeepDDS is considered an effective tool for prioritizing synergistic drug combinations for further experimental validation.
