Cycloaliphatic Quaternary Ammonium Functionalized Poly(oxindole biphenyl) Based Anion-Exchange Membranes for Water Electrolysis: Stability and Performance.

Mechanically robust anion-exchange membranes (AEMs) with high conductivity and long-term alkali resistance are needed for water electrolysis application. In this work, aryl-ether free polyaromatics containing isatin moieties were prepared via super acid-catalyzed copolymerization, followed by functionalization with alkaline stable cyclic quaternary ammonium (QA) cationic groups, to afford high performance AEMs for application in water electrolysis. The incorporation of side functional cationic groups (pyrrolidinium and piperidinium) onto a polymer backbone via a flexible alkyl spacer aimed at conductivity and alkaline stability improvement.

Neurobrucellosis presenting as clinically definite amyotrophic lateral sclerosis.

Unlabelled: Purpose/Aim: We describe the first case of a patient with neurobrucellosis presenting with clinically-definite ALS.

Material And Methods: A 48-year old male patient, in whom the diagnoses of systemic brucellosis and clinically definite ALS were undoubtedly confirmed and were eventually causally interrelated. The disease-specific antibiotic therapy was unsuccessful to slow the evolution of the motor neuron disease and the patient became non ambulatory over time.

Aim: We present the first reported case of a Greek patient with foreign accent syndrome (FAS) secondary to a left temporal-parietal ischemic stroke.
