In this work three different hydrogels were developed to associate, as vehicles, with the synthetic bone substitute GR-HA. One based on an alginate matrix (Alg); a second on a mixture of alginate and chitosan (Alg/Ch); and a third on alginate and hyaluronate (Alg/HA), using Ca2+ ions as cross-linking agents. The hydrogels, as well as the respective injectable bone substitutes (IBSs), were fully characterized fr...
Bioremediation efforts often rely on the application of surfactants to enhance hydrocarbon bioavailability. However, synthetic surfactants can sometimes be toxic to degrading microorganisms, thus reducing the clearance rate of the pollutant. Therefore, surfactant-resistant bacteria can be an important tool for bioremediation efforts of hydrophobic pollutants, circumventing the toxicity of synthetic surfactants ...
As poroqueratoses resultam de uma hiper-proliferação clonal dos queratinócitos, encontrando-se pelo menos descritas seis formas clínicas, que partilham o achado da lamela cornóide no exame histopatológico. Os autores descrevem o caso de uma poroqueratose de Mibelli numa mulher de 27 anos, raça negra, com início na infância, eficazmente tratada com retinóide tópico, apresentando-se as manifestações típicas de um...
Saliva appears as a defence mechanism, against potential negative effects of tannins, in some species of animals which have to deal with these plant secondary metabolites in their regular diets. This study was carried out to investigate changes in parotid saliva protein profiles of sheep Ovis aries)and goats (Capra hircus), induced by condensed tannin ingestion. Five Merino sheep and five Serpentina goats were ...
Introduction Osteosarcoma (OSA) is the most common primary bone tumor in dogs. Between 20 and 25% of canine OSA arise from bones of the axial skeleton and are also the most common extradural spinal neoplasm (46%). Radiographic appearance is nonspecific and inconsistent. Pain without neurological signs is the predominant initial finding with vertebral OSA. Materials and Methods A 8 years cross-bred male dog was...
Mechanisms of thermal isomerization of allyl tetrazolyl ethers derived from the carbocyclic allylic alcohols cyclohex-2-enol and 3-methylcyclohex-2-enol and from the natural terpene alcohol nerol were investigated. In the process of the syntheses of the three 1-aryl-5-allyloxytetrazoles, their rapid isomerization to the corresponding 1-aryl-4-allyltetrazol-5-ones occurred. The experiments showed that the imidat...
Neste trabalho, buscou-se avaliar a suscetibilidade de modelos de tubos gotejadores ao entupimento, quando expostos ao uso de cloreto de potássio (branco e vermelho), aplicados via diferentes qualidades de água. O experimento foi realizado no Laboratório de Irrigação do Departamento de Engenharia Rural da Escola Superior de Agricultura "Luiz de Queiroz" ESALQ/USP, por um período de nove meses, analisando o dese...

O objetivo deste trabalho foi verificar se a administração de doses únicas e de frações diárias da dose letal de monofluoroacetato de sódio (MF) a ovinos induzem a clássica degeneração hidrópico-vacuolar (DHV) dos túbulos uriníferos contornados distais observada no rim de bovinos intoxicados por plantas brasileiras que causam "morte súbita" (PBCMS). MF foi administrado, por via oral, em doses únicas de 0,5 e 1,...
