The expression pattern of connexin 43 (Cx43) in the cochlea is not determined and is controversial. Since the presence of Cx43 is essential for hearing, we re-examined its distribution during postnatal development of rat cochlea. Cx43 protein was expressed in spiral ganglion neurons (SGNs) and their neurite terminals innervating the inner and outer hair cells (IHCs and OHCs) as early as birth (...
Although recent work has suggested that lymphopenia-induced homeostatic proliferation may improve T cell-mediated tumor rejection, there is little direct evidence isolating homeostatic proliferation as an experimental variable, and the mechanism by which improved antitumor immunity occurs via homeostatic proliferation is poorly understood. An adoptive transfer model was developed in which tumor...
Prenatal viral infection has been associated with development of schizophrenia and autism. Our laboratory has previously shown that viral infection causes deleterious effects on brain structure and function in mouse offspring following late first trimester (E9) administration of influenza virus. We hypothesized that late second trimester infection (E18) in mice may lead to a different pattern o...
In a coffee plantation of a coffee 'Acaiá' cultivar (Coffea arabica), on the Midwest of Minas Gerais in Capitólio city, a different kind of coffee tree was found (1989), possibly due to a mutation. It presented larger leaves and grains than those of conventional coffee trees and was named as "Big Coffee VL." The aim of this study was to estimate the genetic diversity of Big Coffee VL progenies ...
Nitric oxide (NO) is a short-lived radical, which modulates synaptic plasticity, neuronal oscillations and cerebral blood flow. NOS-containing neurones can be detected anatomically by nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) histochemistry or by NOS immunohistochemistry. Neuropeptide Y(NPY) is the most abundant peptide in the brain. NPY is connected with several vital fu...
Aminoglycoside-induced cochlear ototoxicity causes hair cell (HC) loss and results in hearing impairment in patients. Previous studies have developed the concept of an ototoxicity-sensitive period during which the cochleae of young mice are more vulnerable to auditory trauma than adults. Here, we compared neomycin-induced ototoxicity at the following four developmental ages in mice: postnatal d...
Inhaled nitric oxide (iNO) is commonly used in the treatment of very ill pre-term newborns. Previous studies showed that exogenous NO could affect endothelial NO synthase (eNOS) activity and expression in vascular endothelial cell cultures or adult rat models, but this has never been fully described in newborn rat lungs. We therefore aimed to assess the effects of iNO on eNOS expression and act...
