In all, 30 adult (45-day-old) Swiss Webster mice were used for light and electron microscopic examination of the presence, number, and location of adrenergic endings in the first molar teeth. Prior to sacrifice, 10 animals received i.p. injections at 8, 6, 4, and 2 hours of 0.5 cc of 20 mg/kg solution of 5-hydroxydopamine (5-OH-DA) as a label for adrenergic(More)
An attempt was made to test the hypothesis (McLeod et al. 1987; Smith et al. 1987) that a certain combination of direct current and alternating current magnetic field exposures at room temperature results in an increase in motility of a marine diatom (Amphora coffeaeformis) to a maximum value. Diatom motility increased as a function of calcium concentration(More)
An analysis of 13 studies of the teratological effects of pulsed magnetic fields on chick embryos from ten independent laboratories permits no clear conclusions. Comparatively little has been done to follow up on the reports by Juutilainen and coworkers on the effects of extremely low-frequency, sinusoidal magnetic fields on the malformation rate in chick(More)

Influence of a 60 Hz, 3 microT, electromagnetic field on the somatic maturation of wistar rat offspring fed a regional basic diet during pregnancy. Braz J Biol 68, 641-648. Extremely low frequency electromagnetic field exposure affects fertilization outcome in swine animal model. The effects of prenatal exposure to a 60-Hz high-intensity electric field on(More)
The aim of this study is to contrast two different sources of information regarding citizenship education in Latin America: curricular guidelines, and students' civic attitudes and practices. When analyzing curricular guidelines, we consider the official national documents of the respective Ministries of Education, whereas regarding civic practices and(More)

OBJECTIVE To determine the effects of autologous fibrinogen (AF) and absorbable barrier membrane (ABM) on periodontal healing of canine experimental grade-III furcation defects. ANIMALS 18 conditioned, laboratory-source, adult Beagles. PROCEDURE Defects were developed bilaterally at the second and fourth premolars and maintained for 12 weeks. Defects(More)

Monkeys were perfused with Karnovsky phosphate-buffered formalin-glutaralde-hyde (PBFGTA). Molars were removed and postfixed in PBF-GTA, demineralized in EDTA, freeze-fractured, and critical-point dried. Odontoblast processes were observed in tubules of the predentine, the pulpal inner third of dentine and in the peripheral dentine, but not in the middle(More)
