Popular musicsl oomposifions are not created out of thin air; they follow a set of aesthetic principles which distinguishes a l~rticular style. Although a complete set of criteria for the comlx~tion of aesthetically pleasing music has thus far defied formalism, some heuristic principles of aesthetics have been established. For example, in jazz improvisation, Coker (1964) remarks: believe that i...

ClC Cl(-) channels are found in almost all organisms, ranging from bacteria to mammals, in which nine Cl(-) channels belonging to the ClC family have been identified. The biophysical properties and physiological functions of ClC Cl(-) channels have been extensively reviewed. In this short review, we will focus on recent results obtained on the X-ray structure and functional properties of the pr...

Molecular farming has been considered as a secure and economical approach for production of biopharmaceuticals. Human TNF Related Apoptosis Inducing Ligand (TRAIL) as a promising biopharmaceutical candidate has been produced in different expression hosts. However, little attention has been paid to molecular farming of the TRAIL in spite of numerous advantages of plant expression systems. Theref...

Cotton fiber is an important commodity throughout the world. Fiber property determines fiber quality and commercial values. Previous studies showed that silencing phytochrome A1 gene (PHYA1) by RNA interference in Upland cotton (Gossypium hirsutum L. cv. Coker 312) had generated PHYA1 RNAi lines with simultaneous improvements in fiber quality (longer, stronger and finer fiber) and other key agr...

We used next generation sequencing to characterize and compare the genomes of the recently derived allotetraploid, Nicotiana tabacum (<200,000 years old), with its diploid progenitors, Nicotiana sylvestris (maternal, S-genome donor), and Nicotiana tomentosiformis (paternal, T-genome donor). Analysis of 14,634 repetitive DNA sequences in the genomes of the progenitor species and N. tabacum revea...
