1. Aspectos Clínicos e Patológicos da Intoxicação Experimental por Pteridium arachnoideum (Dennstatiaceae) em Equinos. 2010. / Clinical and pathological aspects of experimental poisoning by Pteridium Arachnoideum (Dennstatiaceae) in horses. 2010.
A administração das partes aéreas de Pteridium arachnoideum durante períodos de 15 a 57 dias na proporção que variou de 50 a 75% da mistura com capim (Pennicetum purpureum) fornecida, causou em 3 dos 4 equinos do experimento um quadro clínico-patológico que pode ser atribuído a tiaminase, um dos princípios tóxicos da planta. No quadro clínico for

2. Reversible Inactivation of Thiaminase I of Bacillus thiaminolyticus by Its Primary Substrate, Thiamine
Thiaminase I of Bacillus thiaminolyticus is reversibly inactivated when it is incubated with its primary substrate, thiamine, or with one of several structural analogues of thiamine in the absence of an acceptor base. The inactivation reaction is pH and temperature dependent and is stochiometric with respect to thiamine and thiaminase I concentrations. One m

3. Cell-Bound Thiaminase I of Bacillus thiaminolyticus
The distribution of the extracellular enzyme, thiaminase I, was determined for logarithmically growing cultures of Bacillus thiaminolyticus. About 60% of the enzyme is associated with the cells throughout the growth cycle. The remainder of the enzyme is in the culture medium. The release of the cell-bound thiaminase I is examined under a variety of condition

4. Thiamine as an integral component of brain synaptosomal membranes.
Synaptic plasma membranes were prepared from rat cerebral cortex to determine if thiamine was localized in the membranes. The synaptosomes, prepared by discontinuous sucrose gradient centrifugation, were subjected to osmotic shock at pH 9.5 for 10--15 min and subfractionated on a discontinuous sucrose gradient. The two membrane fractions that were obtained w
