Relação causal da vacinação e o fibrossarcoma vacinal felino
Gonçalves, A.; Salas, C.; Nóbrega, C.; Cruz, R.; Esteves, F.; Santos, C.; Mega, A. C.; Santos, R.; Vala, HelenaOs Fibrossarcomas dos felinos domésticos estão reconhecidos desde há 10 anos e têm vindo a alertar os Veterinários, os proprietários e os fabricantes de vacinas, devido à possível ligação do acto de vacinação ao desenvolvimento deste sarcoma. A partir da década de 90, registou-se o aumento dos casos deste tumor na região cervical e interescapular dos gatos, locais frequentemente utilizados para a inoculação de ...
PCR identification of Mycobacterium tuberculosis complex in a clinical sample f...
Ribeiro,M.A.; Barouni,A.S.; Augusto,C.J.; Augusto,M.V.S.; Lopes,M.T.P.; Salas,C.E.A 42-year-old male complaining of thoracic spine pain was admitted to the hospital for evaluation. An X-ray and computer tomography of the thoracic spine showed spondylodiscitis of the L3 lumbar and L2-L3 intervertebral disk. The tuberculin skin test (PPD) was strongly positive. A radioscopy-guided fine needle aspirate of the affected area was cultured but did not reveal the cause of the disease. Two biopsy att...
Anatomical studies of sibling species within neotropical lymnaeids, snail inter...
Pointier,JP; Cazzaniga,NJ; González-Salas,C; Gutiérrez,A; Arenas,JA; Bargues,MD; Mas-Coma,SSeveral anatomical parameters of the reproductive system have been used to distinguish Lymnaea cubensis from L. viatrix, the snail hosts of fascioliasis in South America and the Caribbean area. Three samples have been collected in the type localities of L. cubensis (Cuba), L. viatrix var. A ventricosa (Argentina, Río Negro Lower Valley), and L. viatrix var. B elongata (Peru, Lima), respectively. Only one parame...
BCG lymphadenopathy detected in a BCG-vaccinated infant
Barouni,A.S.; Augusto,C.; Queiroz,M.V.N.P.; Lopes,M.T.P.; Zanini,M.S.; Salas,C.E.Large-scale vaccination with BCG, the live attenuated strain of Mycobacterium bovis, is being adopted around the world, although sporadic complications have occurred after the procedure. Lymphadenopathy is not uncommon especially in babies under one year (0.73% of vaccinated infants), but the swelling subsides within 2 months in most cases, with no medical or surgical treatment. Brazil adopted BCG vaccination p...
The radioprotective effect of a new aminothiol (20-PRA)
Dolabela,M.F.; Pereira,M.T.; Salas,C.E.; Steffani,G.M.; Nelson,D.L.; Piló-Veloso,D.; Lopes,M.T.P.We examined the radioprotective effect of aminothiol 2-N-propylamine-cyclo-hexanethiol (20-PRA) on a human leukemic cell line (K562) following various radiation doses (5, 7.5 and 20 Gy) using a source of 60Co <FONT FACE="Symbol">g</FONT>-rays. At 5 Gy and 1 nM 20-PRA, a substantial protective effect (58%) was seen 24 h after irradiation, followed by a decrease at 48 h (11%). At the high radiation dose (20 Gy) a...
Use of a cysteine proteinase from Carica candamarcensis as a protective agent d...
Genelhu,M.S.; Zanini,M.S.; Veloso,I.F.; Carneiro,A.M.D.; Lopes,M.T.P.; Salas,C.E.We describe the use of a plant cysteine proteinase isolated from latex of Carica candamarcensis as a protective agent during isolation of bacterial DNA following growth in culture of these cells. Between 100 to 720 units of proteinase (1 µg = 6 units) afforded good DNA protection when incubated with various kinds of microorganisms. Agarose gel electrophoresis showed that the resulting DNA was similar in size to...
