Comparative efficacy of selenoureido carbonic anhydrase inhibitors and azole antifungal drugs against clinical isolates of Malassezia pachydermatis. [PDF]

Vet Dermatol
Background – Malassezia pachydermatis (MP) is implicated in severe dermatitis and otitis externa (OE) of companion animals and recently gained attention for its increasing resistance to azole compounds. For this reason, developing novel therapeutic strategies is of great interest. In a previous work, we used reference yeast isolates to evaluate several

Performance of alkaline activated slag at high temperatures

Materiales de Construccion, 2004
This paper presents an investigation into the performance of alkali-activated slag (AAS) mortar exposed to elevated temperatures. Sodium silicate, sodium hydroxide and a mix (waterglass) with a modulus (SiO2/Na20) of 1.5 were used as activators.
