Response of the brain to enrichment
Tập 73 Số 2 - Trang 211-220 - 2001
Before 1960, the brain was considered by scientists to be immutable, subject
only to genetic control. In the early sixties, however, investigators were
seriously speculating that environmental influences might be capable of altering
brain structure. By 1964, two research laboratories proved that the morphology
and chemistry or physiology of the brain could be experientially altered
(Bennett et al....
Molecular basis of mammalian cell invasion by Trypanosoma cruzi
Tập 78 Số 1 - Trang 87-111 - 2006
Establishment of infection by Trypanosoma cruzi, the agent of Chagas' disease,
depends on a series of events involving interactions of diverse parasite
molecules with host components. Here we focus on the mechanisms of target cell
invasion by metacyclic trypomastigotes (MT) and mammalian tissue culture
trypomastigotes (TCT). During MT or TCT internalization, signal transduction
pathways are activa...
Elastase-induced pulmonary emphysema: insights from experimental models
Tập 83 Số 4 - Trang 1385-1396
Several distinct stimuli can be used to reproduce histological and functional
features of human emphysema, a leading cause of disability and death. Since
cigarette smoke is the main cause of emphysema in humans, experimental
researches have attempted to reproduce this situation. However, this is an
expensive and cumbersome method of emphysema induction, and simpler, more
efficacious alternatives h...
Probiotic level effects on growth performance, carcass traits, blood parameters, cecal microbiota, and immune response of broilers
Tập 88 Số 2 - Trang 1011-1021
Probiotic effects on growth performance, carcass traits, blood parameters, cecal
microbiota, and immune response of broilers were studied. Two hundred
one-day-old male chickens were allocated to one of five treatments (four
replicates of 10 birds per treatment): control, and the same control diet
supplemented with 0.005%, 0.01%, 0.015% and 0.02% probiotics. Probiotics in feed
at 0.01% or higher le...
Chemical composition and antibacterial activity of essential oils from Citrus aurantifolia leaves and fruit peel against oral pathogenic bacteria

An overview of chagasic cardiomyopathy: pathogenic importance of oxidative stress
Tập 77 Số 4 - Trang 695-715 - 2005
There is growing evidence to suggest that chagasic myocardia are exposed to
sustained oxidative stress-induced injuries that may contribute to disease
progression. Pathogen invasion- and replication-mediated cellular injuries and
immune-mediated cytotoxic reactions are the common source of reactive oxygen
species (ROS) in infectious etiologies. However, our understanding of the source
and role of ...
Petrography and mineral chemistry of carbonatites and mica-rich rocks from the Araxá complex (Alto Paranaíba Province, Brazil)
Tập 73 Số 1 - Trang 71-98 - 2001
The Araxá complex (16 km²) comprises carbonatites forming a central core and a
complex network of concentric and radial dykes as well as small veins;
additionally, it includes mica-rich rocks, phoscorites and lamprophyres. Fenites
also occur and are represented by Proterozoic quartzites and schists of the
Araxá Group. The petrographic study of 130 borehole samples indicates that the
complex is bas...
