Development of efficient gene prediction algorithms is one of the fundamental efforts in gene prediction study in the area of genomics. In genomic signal processing the basic step of the identification of protein coding ...
N–nitrosodiethylamine cytochrome P450 induction and cytotoxicity evaluation in primary cultures of rat hepatocytes

Aiub, Claudia A.; Gadermaier, Gabriele; Ferreira, Fátima; Felzenszwalb, Israel; Eckl, Peter; Pinto, Luis F. (Scientific Research Publishing, 2011-07)

The primary routes of potential human exposure to N-nitrosodiethylamine (NDEA) are ingestion, inhalation, and dermal contact. Air, diet and smoking contribute to potential human exposure at levels of a few µg of NDEA/day. ...
Ghrelin-induced cSrc activation through constitutive nitric oxide synthase-dependent S-nitrosylation in modulation of salivary gland acinar cell inflammatory responses to Porphyromonas gingivalis

Slomiany, Bronislaw L.; Slomiany, Amalia (Scientific Research Publishing, 2011-07)

A peptide hormone, ghrelin, recognized for its role in the regulation of nitric oxide production has emerged as an important modulator of oral mucosal inflammatory responses to periodontopathic bacterium, P. gingivalis. ...
Gene expression profiling in soybean under aluminum stress: genes differentially expressed between Al-tolerant and Al-sensitive genotypes

Duressa, Dechassa; Soliman, Khairy M.; Taylor, Robert W.; Chen, Dongquan (Scientific Research Publishing, 2011-10)

It is well documented that aluminum (Al) toxicity is the most important constraint to crop production on acid soils and soybean is one of the most Al sensitive plant species. To advance our understanding of the molecular ...
