The use of mice as animal model for testing acute toxicity (LD-50) of toxic sho...
Dias,R.S.; Carmo,L.S.; Heneine,L.G.D.; Rocha,P.H.; Barbosa,C.F.; Rodrigues,R.J.; Linardi,V.R.Acute toxicity test (LD-50) using toxic shock syndrome toxin (TSST-1) was tested in BALB/c, C57BL/6 and Swiss mice. Animals (n = 10) were intraperitoneally injected with TSST-1 (0.01-10.0µg/mouse) followed 4h later by potentiating dose of lipopolysaccharide (75.0µg of LPS - E. coli O111:B4) and cumulative mortality was recorded over 72h. Control animals received either TSST-1 or LPS alone. The data were submitt...
Cinética do fósforo em tecidos de ovinos em crescimento alimentados com diferen...
Dias,R.S.; Roque,A. P.; Vitti,D.M.S.S.; Bueno,I.C.; Godoy,P.B.Foram utilizados 12 cordeiros machos, inteiros, com peso médio de 31,6kg. Os cordeiros foram alimentados com dietas à base de milho e farelo de soja, suplementadas com diferentes fontes de cálcio: calcário calcítico (CC), feno de alfafa (FA), polpa cítrica (PC) e farinha de conchas de ostras (FCO). Os animais receberam injeção de 7,4 MBq do radiofósforo (32P) e após sete dias foram abatidos para posteriores aná...
Polyion Adsorption onto Catanionic Surfaces. A Monte Carlo Study
Dias, R. S.; Pais, A. A. C. C.; Linse, P.; Miguel, M. G.; Lindman, B.The adsorption of a single and negatively charged polyion with varying flexibility onto a surface carrying both negative and positive charges representing a charged membrane surface has been investigated by using a simple model employing Monte Carlo simulations. The polyion was represented by a sequence of negatively charged hard spheres connected with harmonic bonds. The charged surface groups were also repres...
Relation of cervical length at 22-24 weeks of gestation to demographic characte...
Palma-Dias,R.S.; Fonseca,M.M.; Stein,N.R.; Schmidt,A.P.; Magalhães,J.A.Preterm delivery is the main cause of neonatal death and ultrasonographic cervical assessment has been shown to be more accurate than digital examination in recognizing a short cervix. This is a cross-sectional study, involving 1131 women at 22-24 weeks of pregnancy, designed to determine the distribution of cervical length and to examine which variables of demographic characteristics and obstetric history incr...
Social disability of Brazilian mood disorder patients
Tucci,A.M.; Kerr-Corrêa,F.; Dias,R.S.Mood disorders cause many social problems, often involving family relationships. Few studies are available in the literature comparing patients with bipolar, unipolar, dysthymic, and double depressive disorders concerning these aspects. In the present study, demographic and disease data were collected using a specifically prepared questionnaire. Social adjustment was assessed using the Disability Adjustment Sca...
