In order to produce transgenic goats with hG-CSF, a total of 24 adult Saanen and 48 adult undefined breed goats were used as donors and recipients, respectively. Donors were estrus-synchronized with vaginal sponges and superovulated by a treatment with 200 mg FSH given twice daily in decreasing doses over 3 days starting 48 h before sponge removal. Ovulation was induced by injecting 100µg GnRH 36 h after sponge...
A “Bacia do Algarve” corresponde, segundo a literatura científica tradicional, aos terrenos mesocenozóicos que orlam o Sul de Portugal, desde o Cabo de São Vicente ao rio Guadiana (~140km), penetrando irregularmente para o interior entre 3 km a 25 km, sobre terrenos de idade carbónica da Zona Sul Portuguesa. O hiato, de aproximadamente 70 milhões de anos, materializado pela discordância angular entre as rochas ...
The mechanism of Cr(VI)-induced toxicity in plants and animals has been assessed for mitochondrial bioenergetics and membrane damage in turnip root and rat liver mitochondria. By using succinate as the respiratory substrate, ADP/O and respiratory control ratio (RCR) were depressed as a function of Cr(VI) concentration. State 3 and uncoupled respiration were also depressed by Cr(VI). Rat mitochondria revealed a ...
Nematodes studied herein and identified as Parabronema pecariae were collected in 1936 in the States of Rio de Janeiro and Pará and in 1940 in the State of Mato Grosso do Sul, Brazil. This species was proposed, with basis on female specimens that had been described earlier as Parabronema sp. Although the presence of males of P. pecariae was previously reported in Brazil, their description was not provided. The ...
This report deals with the identification of samples of nematodes recovered from Tropidurus nanuzae Rodrigues, 1981, with the description of a new species, and is a part of a major study on helminth parasites of reptiles in Brazil, taking into account previous data on this subject. The main approach is that referring to the first occurrence of subulurid nematodes in a reptilian host, since they have been assign...
Worm burdens recovered from inbred mice strains, namely C57Bl/6, C57Bl/10, CBA, BALB/c, DBA/2 and C3H/He, conventionally maintained in two institutional animal houses in the State of Rio de Janeiro, RJ, Brazil, were analyzed and compared, regarding their prevalences and mean intensities.Three parasite species were observed: the nematodes Aspiculuris tetraptera, Syphacia obvelata and the cestode Vampirolepis nan...
Pocas áreas dentro de la siempre plural realidad universitaria han experimentado un auge tan creciente como la cooperación internacional y todas aquellas medidas tendentes a institucionalizarla. Durante estos últimos diez años, las Universidades europeas han fomentado la creación y desarrollo de Departamentos de Relaciones Internacionales cuyo fin último no es otro que el intento de lograr abrir un mercado únic...
Synhimantus (Synhimantus) magnipapillatus n. sp., mainly considering the outstanding size of the cervical papillae and the delicate structure of the cephalic cordons, is not related to any other species of the genus, except for S. (S.) laticeps, concerning the similarities regarding the spicules, that justify their comparison.
