Early and late neuropathological features of meningoencephalitis associated with Maraba virus infection

Braz. j. med. biol. res; 53 (4), 2020
Maraba virus is a member of the genus Vesiculovirus of the Rhabdoviridae family that was isolated in 1983 from sandflies captured in the municipality of Maraba, state of Pará, Amazônia, Brazil. Despite 30 years having passed since its isolation, little is known about the neuropathology induced by the M...

Expresión inmunohistoquímica de homólogo de fosfatasa y tensina en glioblastoma multiforme y su relación con sobrevida

Int. j. morphol; 37 (3), 2019
El glioblastoma multiforme es el subtipo de gliomas más frecuente en adultos, con una pobre sobrevida promedio posterior al diagnóstico incluso si se aplica el tratamiento óptimo. Se ha estudiado marcadores tumorales de buen pronóstico, siendo controversial la expresión del homólogo de fosfatasa y ...

Preoperative anxiety induces chronic postoperative pain by activating astrocytes in the anterior cingulate cortex region

SUMMARY OBJECTIVE The study aims to explore the relationship between preoperative anxiety and chronic postoperative pain. METHODS A total of forty rats were divided into four groups, control, single-prolonged stress alone, Hysterectomy alone, and SPS+ Hysterectomy. The paw withdrawal mechanical thres...

Effect of periapical inflammation on calcium binding proteins and ERK in the trigeminal nucleus

Acta odontol. latinoam; 32 (2), 2019
Peripheral inflammation induces plastic changes in neurons and glia which are regulated by free calcium and calcium binding proteins (CaBP). One of the mechanisms associated with the regulation of intracellular calcium is linked to ERK (Extracellular Signal-Regulated Kinase) and its phosphorylated condit...

Involvement of adenosine A1 receptor in electroacupuncture-mediated inhibition of astrocyte activation during neuropathic pain

Arq. neuropsiquiatr; 76 (11), 2018
ABSTRACT Neuropathic pain is a chronic pain condition caused by damage or dysfunction of the central or peripheral nervous system. Electroacupuncture (EA) has an antinociceptive effect on neuropathic pain, which is partially due to inhibiting astrocyte activation in the spinal cord. We found that an intr...

Immunohistochemical analysis of retinoblastoma cell phenotype using neuronal and glial cell markers

Arq. bras. oftalmol; 79 (6), 2016
ABSTRACT Purpose: The cellular origin of retinoblastoma is uncertain as constituent tumor cells heterogeneously express markers of both immature and mature retinal cells. An immunohistochemical analysis of cellular origin may yield valuable insights into disease progression and treatment options. This s...

Propentofylline reduces glial scar development following gliotoxic damage in the rat brainstem

Arq. neuropsiquiatr; 74 (9), 2016
ABSTRACT Propentofylline is a xanthine derivative that depresses activation of glial cells, whose responses contribute to neural tissue damage during inflammation. Ethidium bromide injection into the central nervous system induces local oligodendroglial and astrocytic loss, resulting in primary demyelina...
