Lymphomas and neuroblastoma are the two commonly diagnosed cancers in childhood. Despite extensive studies in cytogenetic and mutations in childhood cancers, new diagnoses were still reported. This is due to multifactorial characteristic of the diseases and a lack of systematic-level information on genetic interaction and pathways between markers to understand the development and progression of the diseases. This study aims to sought a system biology approach to infer gene regulatory networks for lymphomas and neuroblastoma. Results demonstrated that our approach simplifies complex genetic interactions without losing important biological information of the genes. Candidate markers that infer lymphoma and neuroblastoma and their relevant pathways were identified.

Precision medicine information retrieval (PM IR) is about matching the most relevant scientific articles to an individual patient for reliable disease treatment. To achieve effectiveness and efficiency, the task usually consists of two stages: conventional information retrieval and reranking. Many approaches have been proposed for reranking. However, the performance is still far from satisfactory. In this work, we propose a regression-based reranking scheme for PM IR which uses labelled data regardless of empirical knowledge from similar but not identical documents set. Experiments validate that the performance of our approach is significantly better than that of the state-of-the-art approaches.

A nonlinear single-slope ADC with SOC integrated local contrast stretch using a configurable multi-frequency counter for bio-microfluidic imaging is presented in this paper. Compared with the conventional off-chip global contrast stretching algorithm, this method does not degrade image quality at the interested light intensity range (cell) at the cost of unconsidered range (sheath fluid) and can be integrated into CMOS image sensor directly. Meanwhile, this method provides higher precision of cell image for the later super-resolution reconstruction. The simulation results indicate that more details of cell image can be obtained in this method.

For positron emission tomography (PET), successive approximation register (SAR) analog-to-digital converter (ADC) and switched-capacitor (SC) low-pass filter implemented in tsmc 0.18-um CMOS process is presented. To reduce DAC switching energy and layout size, a hybrid resistor-capacitor DAC is applied. To save energy, asynchronous control logic to drive the ADC is used. A pre-amplifier based comparator circuit is built to reduce the kickback noise from the dynamic latch. The proposed filter uses cascades of first-order and second-order biquad seting blocks. In order to reach the largest possible input dynamic range, the method of dynamic range scaling and minimum capacitor scaling is used.

In this paper, we imaged the retina of wild-type and the triple-transgenic mouse model of Alzheimer’s disease (3xTg- AD) with optical coherence tomography to assess changes in the retinal tissue associated with the Alzheimer’s disease. Texture analysis allowed to identify differences between groups at the age of four months, and to find biomarkers of disease progression. Furthermore, our findings suggest that specific layers of the retina may play a fundamental role in the assessment of early changes associated with the Alzheimer’s disease.

Lysine malonylation is a newly discovered post-translational modification of proteins, which plays an important role in regulating many cellular functions. Several approaches are available to identify malonylation proteins and its malonylation sites, however; experimental identification of malonylation sites is often laborious and costly. Therefore, computational schemes are needed to identify potential malonylation sites prior to in vitro experimentation. In this paper, a novel computational scheme iLMS (Identification of Lysine-Malonylation Sites) has been developed by combining primary sequences and evolutionary features via a support vector machine classifier. The final iLMS scheme achieved a robust performance in cross-validation test in both human and mouse datasets. For the mouse data, the iLMS predictor outperformed other existing implementations. The iLMS is a promising computational scheme for the prediction of malonylation sites.

DNA barcoding is widely used in fields, such as taxonomy and species identification. Conventional DNA barcoding sequences employ uninformative or repeat nucleotides in known groups of taxa within a monophylum. Herein, we propose a decision theory-based DNA barcode that tests for the ribulose bisphosphate carboxylase gene (rbcL). The proposed method can generate shorter DNA barcodes called single nucleotide polymorphism (SNP) tags, which shorten rbcL sequences from their full length (400–654 bp) to 25-bp DNA tags. These DNA tags are then represented by quick response (QR) codes containing the species names, accession numbers, and DNA tag sequences. Our proposed method can efficiently reduce data storage and provide DNA barcoding for various plant species.

Deep learning technologies are permeating every field from image and speech recognition to computational and systems biology. However, the application of convolutional neural networks to 'omics' data poses some difficulties, such as the processing of complex networks structures as well as its integration with transcriptome data. Here, we propose a convolutional neural network (CNN) approach that combines spectral clustering information processing to classify lung cancer. The developed spectral-convolutional neural network based method achieves success in integrating protein interaction network data and gene expression profiles to classify lung cancer.
