Role of Endogenous Vitamin E in Renal Ischemic Preconditioning Process: Differences between Male and Female Rats

Background: Antioxidants such as α-tocopherol (vitamin E) and β-carotene (vitamin A) play an important role in protective effect of repeated brief periods of ischemia, namely ischemic preconditioning (IPC). Values of these antioxidants were investigated and compared after induction of ischemia reperfusion (IR) and kidney IPC in both male and female rats. Methods: Forty eight Wistar rats were di...

Forging New Ties between E. coli Genes

A recent study in Nature (Isalan et al., 2008) has examined the effects of systematically adding new transcriptional interactions in the bacterium Escherichia coli. Surprisingly, the majority of the engineered connections have no effect on growth, and in some cases the new connections enhance fitness. These findings reveal insights into the robustness and evolvability of gene networks.

Molecular and Functional Profiling of the Polyamine Content in Enteroinvasive E. coli : Looking into the Gap between Commensal E. coli and Harmful Shigella

Polyamines are small molecules associated with a wide variety of physiological functions. Bacterial pathogens have developed subtle strategies to exploit polyamines or manipulate polyamine-related processes to optimize fitness within the host. During the transition from its innocuous E. coli ancestor, Shigella, the aetiological agent of bacillary dysentery, has undergone drastic genomic rearran...

The Study of Differences between E-commerce Impacts on Developed Countries and Developing Countries, Case Study: USA and Iran

This study determines the impact of E-commerce (EC) on some of important economic criteria including total factor productivity( TFP) of Iran country as a developing country in comparison with US standard as a developed country through analyzing and calculating interrelated issues. The model is based on both econometrics and growth accounting approach to fill the gaps of previous studies. On the...
