Oral candidiasis is the most common opportunistic infection affecting patients with the human immunodeficiency virus. Miconazole buccal tablets or miconazole gel are approved for the treatment of oropharyngeal candidiasis. However, buccal films present more flexibility and also offer protection for the wounded mucosa, reducing pain. Due to their small size and thickness, buccal films may improve patients' compliance, compared to tablets. Additionally, they may increase the relatively short residence time on the mucosa of oral gels, which are easily removed by saliva...

Molinate is a thiocarbamate herbicide used in rice crop protection. As other pesticides, molinate is a recognized environmental pollutant and bio-accumulated by some wildlife forms. Gulosibacter molinativorax ON4(T) is able to hydrolyse molinate into metabolites which are further degraded by other un-related bacteria. Hence, it can be used in molinate bioremediation processes. The aim of this work was to investigate the possibility of producing G. molinativorax ON4(T) microparticles, using different non-toxic biopolymers (arabic gum, modified chitosan, calcium alginate and sodium alginate) as encapsulating agents by a spray-drying process...
