The abundance of cellular proteins is determined largely by the rate of transcription and translation coupled with the stability of individual proteins. Although we know a great deal about global transcript abundance, little is known about global protein stability. We present a highly parallel multiplexing strategy to monitor protein turnover on a global scale by coupling flow cytometry with mi...

the thermal degradation of polyethylene (pe) was carried out in the absence and presence ofcatalystes x-zeolite and silica-alumina at different temperatures. the optimum pe/catalysisratio was 0.25:0.05 g/g, which produced highest degradation value. pe and pe/catalysis werecharacterized by thermogravimetric analysis. the thermal degradation properties of polymerhave been studied by infrared spec...

Dimerization process is essential for producing copolymers. The features of dimerization process like thermal-oxidative degradation should be well known to reach maximum efficiency and a superior reactor design. Also, the degradation mechanism of biodegradable polymers is important during sterilization processes. Thermal-oxidative degradation of PGA, PLLA, and their binary copolymers was invest...

so far, different methods have been applied to clean up soils contaminated with oil. bioremediation is one of the clean up technologies which uses microorganisms or microbial processes to degrade oil contaminations in soils. this study evaluates the applicability of cow manure as bioremediation alternative for soils spiked with petroleum hydrocarbons. target contaminant of this research was die...

1. When Escherichia coli was grown exponentially in a defined medium at 35 degrees , the rate of protein breakdown was initially rapid, but decreased to 0.6%/hr. after about 30min. The latter rate was maintained for at least 3.5hr. 2. The initial rapid rate may have been due to the presence of a small protein fraction (about 1%) that was degraded with a half-life of 13min. 3. The rate of protei...

To deal with the growing scale of molecular systems, sophisticated modelling techniques have been designed in recent years to reduce the complexity of mathematical models. Among them, a widely used approach is delayed reaction for simplifying multistep reactions. However, recent research results suggest that a delayed reaction with constant time delay is unable to describe multistep reactions a...

Gene expression profiles are an increasingly common data source that can yield insights into the functions of cells at a system-wide level. The present work considers the limitations in information content of gene expression data for reverse engineering regulatory networks. An in silico genetic regulatory network was constructed for this purpose. Using the in silico network, a formal identifiab...
