Circadian rhythms play a fundamental role at all levels of biological organization. Understanding the mechanisms and implications of circadian oscillations continues to be the focus of intense research. However, there has been no comprehensive and integrated way for accessing and mining all circadian omic datasets. The latest release of CircadiOmics (http://circadiomics.ics.uci.edu) fills this gap for providing the most comprehensive web server for studying circadian data. The newly updated version contains high-throughput 227 omic datasets corresponding to over 74 million measurements sampled over 24 h cycles...

In maize ( Zea mays L.), unilateral cross-incompatibility (UCI) is controlled by Gametophyte factors ( Ga ), including Ga1 , Ga2 , and Tcb1 ; however, the molecular mechanisms underpinning this process remain unexplored. Here, we report the pollination phenotype of an inbred line, 511L, which carries a near-dominant Ga2 - S allele. We performed a high-throughput RNA sequencing (RNA-Seq) analysis of the compatible and incompatible crosses between 511L and B73, to identify the transcriptomic differences associated with Ga2 -mediated UCI...

Hua Fang, Zhaoyang Zhang
Big longitudinal data provide more reliable information for decision making and are common in all kinds of fields. Trajectory pattern recognition is in an urgent need to discover important structures for such data. Developing better and more computationally-efficient visualization tool is crucial to guide this technique. This paper proposes an enhanced projection pursuit (EPP) method to better project and visualize the structures (e.g. clusters) of big high-dimensional (HD) longitudinal data on a lower-dimensional plane...

INTRODUCTION: Isolated aortic valve replacement (AVR) in elderly patients is associated with increased operative risk, due to higher prevalence of associated risk factors and other comorbidities, making outcome prediction essential. In patients with symptomatic severe aortic disease, advanced age is often a reason for a transcatheter rather than surgical aortic valve replacement. In the era of TAVI, there has been renewed interest in the outcomes of conventional AVR for high and intermediate risk patients...

Colorectal carcinoma (CRC) has been shown to have both genetic and environmental factors that can promote carcinoma development. Previous studies have found ethnic differences in the distribution of molecular phenotypes of CRC. Very little specific data exist regarding Hispanic CRC, and these data primarily focus on epidemiology or location of carcinoma. Our retrospective study analyzed 562 Caucasian, Asian, and Hispanic CRC patients at the UCI Medical Center from 2004 to 2012. The results showed that there were no statistically significant differences with respect to mean age, gender or site of carcinoma among the three ethnic groups...

The umbilical cord (UC), the connection between mother and fetus via the umbilical vessels, carries nutrients and oxygenated blood to the fetus through the umbilical vein and removes deoxygenated blood and waste products via the umbilical arteries. It is designed to protect blood flow to the fetus during pregnancy. In equine medicine, only a few studies have described the UC, and most of these involved Thoroughbreds. The present study describes and compares the macroscopic features of the equine umbilical cord in three different breeds and in relation to the foal's gender...

Weiran Song, Hui Wang, Paul Maguire, Omar Nibouche
Partial Least Squares Discriminant Analysis (PLS-DA) is one of the most effective multivariate analysis methods for spectral data analysis, which extracts latent variables and uses them to predict responses. In particular, it is an effective method for handling high-dimensional and collinear spectral data. However, PLS-DA does not explicitly address data multimodality, i.e., within-class multimodal distribution of data. In this paper, we present a novel method termed nearest clusters based PLS-DA (NCPLS-DA) for addressing the multimodality and nonlinearity issues explicitly and improving the performance of PLS-DA on spectral data classification...

Motivation: Single-cell RNA-sequencing (scRNA-seq) offers unprecedented resolution for studying cellular decision-making processes. Robust inference of cell state transition paths and probabilities is an important yet challenging step in the analysis of these data. Results: Here we present scEpath, an algorithm that calculates energy landscapes and probabilistic directed graphs in order to reconstruct developmental trajectories. We quantify the energy landscape using "single-cell energy" and distance-based measures, and find that the combination of these enables robust inference of the transition probabilities and lineage relationships between cell states...

BACKGROUND: Maintenance of mucosal healing is recommended during the treatment of ulcerative colitis (UC). However, symptoms of UC often do not reflect mucosal disease activity. Fecal markers such as calprotectin, lactoferrin, and hemoglobin have been reported to correlate well with the Mayo endoscopic subscore (MES) and are being considered alternative monitoring tools in endoscopy. Ulcerative Colitis Endoscopic Index of Severity (UCEIS) is a new and more detailed endoscopic scoring system compared to MES...

We evaluated the use of antimicrobials expressed as defined daily doses (DDDs) per 1,000 patient days and days of therapy (DOT) per 100 occupied bed-days in a intensive care unit (ICU) of a general hospital in Barcelona, Spain, before and after implementation of an antimicrobial stewardship (AMS) program (2007 to 2010 versus 2011 to 2015). The quarterly costs of antimicrobials used in the ICU and its weight in the overall hospital costs of antimicrobials were calculated. The effect of the applied AMS program on DDDs and DOT time series data was analyzed by means of intervention time series analysis...

Leonardo M Honório, Daniele A Barbosa, Edimar J Oliveira, Paulo A Nepomuceno Garcia, Murillo F Santos
This work presents a new approach for solving classification and learning problems. The Successive Geometric Segmentation technique is applied to encapsulate large datasets by using a series of Oriented Bounding Hyper Box (OBHBs). Each OBHB is obtained through linear separation analysis and each one represents a specific region in a pattern's solution space. Also, each OBHB can be seen as a data abstraction layer and be considered as an individual Kernel. Thus, it is possible by applying a quadratic discriminant function, to assemble a set of nonlinear surfaces separating each desirable pattern...

Gregor Urban, Niranjan Subrahmanya, Pierre Baldi
Deep learning methods applied to problems in chemoinformatics often require the use of recursive neural networks to handle data with graphical structure and variable size. We present a useful classification of recursive neural network approaches into two classes, the inner and outer approach. The inner approach uses recursion inside the underlying graph, to essentially "crawl" the edges of the graph, while the outer approach uses recursion outside the underlying graph, to aggregate information over progressively longer distances in an orthogonal direction...
