Dynamic exercise evokes sustained blood pressure and heart rate (HR) increases. Although it is well accepted that there is a CNS mediation of cardiovascular adjustments during dynamic exercise, information on the role of specific CNS structures is still limited. The bed nucleus of the stria terminalis (BST) is involved in exercise-evoked cardiovascular(More)
Magnetic anomalies may be used to constrain magma ascent and are useful as precursors to eruptions especially when correlated with other geophysical and geochemical data. In this paper we present multiparameter data on the magnetics, dome morphology, geochemistry and seismicity associated with the December 2000^January 2001 eruptions, the largest of the(More)
Ramaria flavo-brunnescens collected in autumn from 1990 to 1994 was orally administered to 11 sheep. These animals were dosed with 100-430 g/kg bw administered over 3-13 d. Six sheep showed clinical signs and 4 of them died. The mininum toxic dose was of 150 g/kg bw. Clinical signs were anorexia, hyperthermia, dyspnea, polyuria, ataxy, muscle tremors and(More)
Craniofacial anomalies, eye malformations, and permanent flexures of the forelimbs are common malformations seen in ruminants grazing semiarid rangelands of Northeastern Brazil. To investigate the cause of these malformations, we fed 2 suspected plants, Mimosa tenuiflora or Prosopis juliflora, to groups of 4 pregnant goats each. Fresh green M. tenuiflora(More)
We evaluated age- and sex-dependent differences in heart rate variability (HRV) during the 6-min walk test (6MWT) in healthy adults. We also evaluated the intensity of the 6MWT based on HRV. 78 participants aged 40-49, 50-59, 60-69, and ≥ 70 years (42 females; 36 men) performed the 6MWT. Heart rate and HRV were monitored 1 min at rest and during the last(More)
Miconia cinnamomifolia is a forest species with occurrence in Brazilian Atlantic rainforest. Seedlings from a nursery located in Viçosa (State of Minas Gerais, Brazil) presented symptoms of damping-off. Based on morphology and the ITS sequence, the fungus was identified as belonging to the species Botrytis cinerea. This is the first record of this(More)
