Alkyl deoxy-arabino-hexopyranosides: synthesis, surface properties, and biologi...
Silva, Filipa; Goulart, Margarida; Justino, Jorge; Neves, Ana; Santos, F.; Caio, J.; Lucas, S.; Newton, A.; Sacoto, D.; Barbosa, E.; Santos, M. S.Octyl and dodecyl glycosides possessing 2-deoxy-arabino-hexopyranoside moieties belonging to the D-and L-series in their alpha- and beta-forms were synthesized by reaction of an acetyl protected glycal with octanol or dodecanol, catalyzed by triphenylphosphine hydrobromide, followed by deprotection. Their surface properties were studied and discussed in terms of the adsorption and aggregation parameters, pC(20)...
Avaliação dos comportamentos de aves poedeiras utilizando seqüência de imagens
Barbosa Filho,José A. D.; Silva,Iran J. O.; Silva,Marco A. N.; Silva,Caio J. M.A grande preocupação com o uso de gaiolas dá-se quanto ao espaço oferecido às aves poedeiras, o qual, certamente, afeta seu bem-estar. Sendo assim, este trabalho teve o objetivo de avaliar aspectos relacionados ao comportamento e bem-estar animal, comparando o sistema de criação alternativo (com cama e ninho) com o sistema convencional em gaiolas. Para isso, dois grupos de 20 aves (10 Hy-Line W36 e 10 Hy-Line B...
Study of Coronary Sinus Flow Reserve Through Transesophageal Doppler Echocardio...
Ramos Filho,José; Ramires,José A. F.; Turina,Marko; Medeiros,Caio J.; Lachat,Mário; Tsutsui,JeaneOBJECTIVE - To evaluate the Coronary Flow Reserve in the Coronary Sinus through transesophageal Doppler echocardiography in normal subjects. METHODS - We obtained technically adequate flow samples for analysis in 10 healthy volunteers (37±8 years, 5 men) with no history of heart or systemic disease and with mean left ventricular mass index by transthoracic echocardiography of 87±18 g/m². Coronary sinus flow vel...
Exposure to acellular blood products and risk of HIV infection in hemophiliacs ...
Proietti,Fernando A.; Proietti,Anna Barbara F. C.; Costa,Maria Fernanda F. L.; Antunes,Carlos M. F.; Guimarães,Mark D. C.; Paulino,Urquiza H. M.Results of a HIV prevalence study conducted in hemophiliacs from Belo Horizonte, Brazil are presented. History of exposure to acellular blood components was determined for the five year period prior to entry in the study, which occurred during 1986 and 1987. Patients with coagulations disorders (hemophilia A = 132, hemophilia B = 16 and coagulation disorders other than hemophilia = 16) were transfused with liqu...
