Oxidative stress, cytokine/chemokine and disruption of blood–Brain barrier in n...
Teixeira, Antonio Lucio; Barichello, Tatiana; Lemos, Joelson C.; Generoso, Jaqueline S.; Cipriano, Andreza L.; Milioli, Graziele L.We verify the levels of cytokine/chemokine, myeloperoxidase activity, oxidative stress and disruption of BBB in hippocampus and cortex of the neonate Wistar rats after meningitis by S. agalactiae. In the hippocampus the levels were increased of CINC-1 at 6 h and 12 h, IL-1β at 6, 12 and 24 h, IL-6 at 6, 24 and 96 h, IL-10 at 24, 48 and 96 h and TNF-α at 24 h and 96 h. In the cortex the CINC-1 and IL-1β levels w...
Brain–blood barrier breakdown and pro-inflammatory mediators in neonate rats su...
Barichello, Tatiana; Fagundes, Glauco D.; Generoso, Jaqueline S.; Moreira, Ana Paula; Costa, Caroline S.; Zanatta, Jessiele R.; Simões, Lutiana R.Neonatal meningitis is an illness characterized by inflammation of the meninges and occurring within the birth and the first 28 days of life. Invasive infection by Streptococcus pneumoniae, meningitis and sepsis, in neonate is associated with prolonged rupture of membranes; maternal colonization/illness, prematurity, high mortality and 50% of cases have some form of disability. For this purpose, we measured bra...
Environmental enrichment restores cognitive deficits induced by experimental ch...
Barichello, Tatiana; Fagundes, Glauco D.; Generoso, Jaqueline S.; Dagostin, Caroline S.; Simões, Lutiana R.; Vilela, Márcia C.; Comim, Clarissa M.To evaluate the influence of environmental enrichment (EE) on memory, cytokines, and brain-derived neurotrophic factor (BDNF) in the brain of adult rats subjected to experimental pneumococcal meningitis during infancy. On postnatal day 11, the animals received either artificial cerebrospinal fluid (CSF) or Streptococcus pneumoniae suspension intracisternally at 1 × 106 CFU/mL and remained with their mothers unt...
Exercise training prevents skeletal muscle damage in an experimental sepsis model
Coelho, Carla Werlang; Jannig, Paulo R.; Souza, Arlete B. de; Fronza Jr., Hercilio; Westphal, Glauco A; Petronilho, Fabricia; Constantino, LarissaOBJECTIVE: Oxidative stress plays an important role in skeletal muscle damage in sepsis. Aerobic exercise can decrease oxidative stress and enhance antioxidant defenses. Therefore, it was hypothesized that aerobic exercise training before a sepsis stimulus could attenuate skeletal muscle damage by modulating oxidative stress. Thus, the aim of this study was to evaluate the effects of aerobic physical preconditi...
