Acidophilic adenoma of the pituitary with polyneuropathy [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 1974 An acromegalic man aged 70 developed progressive polyneuropathy affecting mainly the extremities. The peripheral nerves showed hypertrophic neuropathy and accumulation of acid mucopolysaccharides in the nerve without `onion bulb' formation. The myelin showed a lamellar disintegration and vesicular formation.

Evaluation of microbial diversity of the microbial mat from the extremely acidic Lake Robule (Bor, Serbia) [PDF]
Botanica Serbica, 2017 Extremely acidic environments are frequently formed in areas impacted by mining activities, and Lake Robule is such an ecosystem. Although an extreme environment, Lake Robule is inhabited by acidophilic microorganisms. We investigated biodiversity of the

High Free‐Volume Imidazole‐Based Ionomers for High‐Temperature Proton Exchange Membrane Fuel Cells
Advanced Science, EarlyView.High free‐volume imidazole‐based ionomers (PF4IM‐72) enable enhanced phosphoric acid uptake and efficient proton transport, delivering peak power densities of 0.645 W cm−2 at 160 °C and 0.838 W cm−2 at 200 °C in HT‐PEMFCs. This work highlights a promising platform for next‐generation ionomers with improved high‐temperature performance and stability ...
