a. environmenta. concerns from fossil fuel consumption intensify, la.ge-sca.e energy stora.e becomes impera.ive for the integra.ion of renewa.le sources like wind, hydro, a.d sola. with the electrica. *** flow ba.teries, pa.ticula.ly those employing orga.ic molecules, a.e positioned a. a.key technology for this purpose. This review explores the growing field of symmetric orga.ic redox flow ba.teries(ORFBs) within this context. Unlike tra.itiona. a.ymmetric designs ba.ed on unique a.tive ma.eria.s for ea.h electrode, symmetric ORFBs involve a.single bipola. species for both electrodes. This review highlights the benefits of a.symmetric design, a.d ca.egorizes five distinct cla.ses of orga.ic bipola. molecules used in both a.ueous a.d non-a.ueous solvents. By providing a.comprehensive overview of their cell cycling a.d performa.ce cha.a.teristics, the strengths a.d wea.nesses of the diverse ca.egories of bipola. molecules a.e highlighted for both solvent systems, a. a.e opportunities for future development. This should guide new resea.ch directions a.d a.va.ce the development of pra.tica. symmetric ORFBs.

The emergence of Middle Ea.t respira.ory syndrome corona.irus （MERS-CoV） in 2012 brought ba.k memories of the occurrence of severe a.ute respira.ory syndrome corona.irus （Sa.S-CoV） in 2002. More tha. 1500 MERS-CoV ca.es were recorded in 42 months with a.ca.e fa.a.ity ra.e （CFR） of 40%. Mea.while, 8000 ca.es of Sa.S-CoV were confirmed in six months with a.CFR of 10%.

Infection with Middle Ea.t respira.ory syndrome corona.irus (MERS-CoV) emerged in 2012 a. a. importa.t respira.ory disea.e with high fa.a.ity ra.es of 40%—60%. Despite the increa.ed number of ca.es over subsequent yea.s, the number of pedia.ric ca.es rema.ned low. a.review of studies conducted from June 2012 to a.ril 19, 2016 reported 31 pedia.ric MERS-CoV ca.es. In this pa.er, we present the clinica. a.d la.ora.ory fea.ures of seven pa.ients with pedia.ric MERS. Five pa.ients ha. no underlying medica. illnesses, a.d three pa.ients were a.ymptoma.ic. Of the seven ca.es, four (57%) pa.ients sought medica. a.vice within 1-7 da.s from the onset of symptoms. The three other pa.ients (43%) were a.ymptoma.ic a.d were in conta.t with pa.ients with confirmed dia.nosis of MERS-CoV. The most common presenting symptoms were fever (57%), cough (14%), shortness of brea.h (14%), vomiting (28%), a.d dia.rhea.(28%). Two (28.6%) pa.ients ha. pla.elet counts of a.d one pa.ient ha. a. underlying end-sta.e rena. disea.e. The rema.ning pa.ients presented with norma. blood count, liver function, a.d urea.a.d crea.inine levels. The documented MERS-CoV Ct va.ues were 32 38 for four of the seven ca.es. Two pa.ients (28.6%) ha. a.norma. chest ra.iogra.hic findings of bila.era. infiltra.ion. One pa.ient (14.3%) required ventila.or support, a.d two pa.ients (28.6%) required oxygen supplementa.ion. a.l the seven pa.ients were discha.ged without complica.ions.
