A new class of organic photovoltaic materials: poly(rod-coil) polymers having alternative conjugated and non-conjugated segments.

A new class of organic photovoltaic materials, poly(rod-coil) polymers composed of alternatively definite conjugated and non-conjugated segments, have been proposed. The first five examples based on polyurethane chemistry showed photovoltaic performance surpassing the reference compound, but less dependent on their molecular weight.

Identification of common carp (Cyprinus carpio) microRNAs and microRNA-related SNPs.

Background: MicroRNAs (miRNAs) exist pervasively across viruses, plants and animals and play important roles in the post-transcriptional regulation of genes. In the common carp, miRNA targets have not been investigated. In model species, single-nucleotide polymorphisms (SNPs) have been reported to impair or enhance miRNA regulation as well as to alter miRNA biogenesis.

Transcriptome analysis reveals the time of the fourth round of genome duplication in common carp (Cyprinus carpio).

Background: Common carp (Cyprinus carpio) is thought to have undergone one extra round of genome duplication compared to zebrafish. Transcriptome analysis has been used to study the existence and timing of genome duplication in species for which genome sequences are incomplete. Large-scale transcriptome data for the common carp genome should help reveal the timing of the additional duplication event.
