As environmental concerns from fossil fuel consumption intensify, large-scale energy storage becomes imperative for the integration of renewable sources like wind, hydro, and solar with the electrical *** flow batteries, particularly those employing organic molecules, are positioned as a key technology for this purpose. This review explores the growing field of symmetric organic redox flow batteries(ORFBs) within this context. Unlike traditional asymmetric designs based on unique active materials for each electrode, symmetric ORFBs involve a single bipolar species for both electrodes. This review highlights the benefits of a symmetric design, and categorizes five distinct classes of organic bipolar molecules used in both aqueous and non-aqueous solvents. By providing a comprehensive overview of their cell cycling and performance characteristics, the strengths and weaknesses of the diverse categories of bipolar molecules are highlighted for both solvent systems, as are opportunities for future development. This should guide new research directions and advance the development of practical symmetric ORFBs.

congenital bilateral absence of vas deferens （cBAVD） is a manifestation of the mildest form of cystic fibrosis （cF） and is characterized by obstructive azoospermia in otherwise healthy patients. Owing to the availability of assisted reproductive technology, cBAVD patients can father children. These fathers are at risk of transmitting a mutated allele of the cF transmembrane conductance regulator （cFTR） gene, responsible for cF, to their offspring. The identification of mutations in both cFTR alleles in cBAVD patients is a crucial requirement for calculating the risk of producing a child with full-blown cF if the female partner is a healthy cF carrier. However, in the majority of cBAVD patients, conventional mutation screening is not able to detect mutations in both cFTR alleles, and this difficulty hampers the execution of correct genetic counselling. To obtain information about the most represented cFTR mutations in cBAVD patients, we analysed 23 cBAVD patients, 15 of whom had a single cFTR mutation after screening for 36 mutations and the 5T allele. The search for the second cFTR mutation in these cases was performed by using a triplex approach：（i） first, a reverse dot-blot analysis was performed to detect mutations with regional impact; （ii） next, multiple ligation-dependent probe amplification assays were conducted to search for large rearrangements; and （iii） finally, denaturing high-performance liquid chromatography was used to search for point mutations in the entire coding region. Using these approaches, the second cFTR mutation was detected in six patients, which increased the final detection rate to 60.8%.
