There exist many tools and methods for construction of co-expression network from gene expression data and for extraction of densely connected gene modules. In this paper, a method is introduced to construct co-expression network and to extract co-expressed modules having high biological significance. The proposed method has been validated on several well known microarray datasets extracted from a diverse set of species, using statistical measures, such as p and q values. The modules obtained in these studies are found to be biologically significant based on Gene Ontology enrichment analysis, pathway analysis, and KEGG enrichment analysis...

Immunosuppression is involved in refractory innate and adaptive immune responses and is considered to be the predominant driving force for mortality in sepsis. The cecal ligation and puncture (CLP) model is regarded as a golden standard model for sepsis study, but the turning point of over-inflammation to immunosuppression was reported differently. Herein, systematic investigation on the turning point of over-inflammation to immunosuppression in CLP mice model was carried out. The results showed only the mortality of mice challenged with of Pseudomonas aeruginosa on Day 1 not other days after the surgery was higher than that of other mice with Sham surgery, suggesting Day 1 after the CLP surgery might be the turning point...

The response mechanisms of microalgal mutant Chlorella PY-ZU1 cells were investigated in their removal of antibiotic tilmicosin from wastewater under 15% CO2. Low concentrations (0.01-2mgL(-1)) of tilmicosin in wastewater stimulated the growth of microalgal cells, whereas high concentrations (5-50mgL(-1)) of tilmicosin significantly inhibited cell growth. When initial tilmicosin concentration increased from 0 to 50mgL(-1), fractal dimension of microalgal cells monotonically increased from 1.36 to 1.62 and cell size monotonically decreased from 4...
