In the treatment of genetic disorders, repairing defective pre-mRNAs by RNA trans-splicing has become an emerging alternative to conventional gene therapy. Previous studies have made clear that the design of the binding domains of the corrective RNA trans-splicing molecules (RTMs) is crucial for their optimal functionality. We established a reporter-based ...

Breast cancer-related lymphoedema (BCRL) affects 24-42% of patients following treatment for breast cancer. The gold standard method of measuring hand swelling associated with BCRL is to use water displacement (volumeter). This is not always possible in the clinical setting and the figure-of-eight method, which involves wrapping a simple measuring tape ...

The mating calls of male túngara frogs, Physalaemus pustulosus, attract intended (conspecific females) and unintended (eavesdropping predators and parasites) receivers. The calls are complex, having two components: a frequency-modulated "whine" followed by 0-7 harmonic bursts or "chucks". The whine is necessary and sufficient to elicit phonotaxis from females and the ...
