Approximately 30% of patients with mesial temporal lobe epilepsy do not respond to treatment with antiepileptic drugs. We have previously shown that transplantation of mononuclear bone marrow cells (BMC) has an anticonvulsant effect in acute epilepsy. Here, we used pilocarpine to induce epilepsy in rats and studied the effects of BMC injected intravenously(More)
Status epilepticus (SE) is a severe clinical manifestation of epilepsy associated with intense neuronal loss and inflammation, two key factors involved in the pathophysiology of temporal lobe epilepsy. Bone marrow mononuclear cells (BMMC) attenuated the consequences of pilocarpine-induced SE, including neuronal loss, in addition to frequency and duration of(More)
Chagas disease, caused by Trypanosoma cruzi infection, is a leading cause of heart failure in Latin American countries. In a previous study, we showed beneficial effects of granulocyte colony-stimulating factor (G-CSF) administration in the heart function of mice with chronic T. cruzi infection. Presently, we investigated the mechanisms by which this(More)
Query answering has been addressed as a key issue in distributed environments such as Peer Data Management Systems (PDMS). An important step in this process regards query routing, i.e., how to find peers that are most likely to provide matching results according to the semantics of a submitted query. To help matters, we argue that semantic information(More)
Undernourished mice infected (UI) submitted to low and long-lasting infections by Schistosoma mansoni are unable to develop the hepatic periportal fibrosis that is equivalent to Symmers' fibrosis in humans. In this report, the effects of the host's nutritional status on parasite (worm load, egg viability and maturation) and host (growth curves, biology,(More)
We report the presence of Chikungunya (CHIKV) RNA in the blood, urine and semen during the acute phase of the disease in an adult with a dual infection with Dengue virus type 3. The patient, a 25 yr-old man from Salvador, Brazil, reported a 6-day duration of high fever, arthralgia, myalgia, headache and photophobia.Blood and semen specimens were positive(More)
Zika virus (ZIKV) infection has been associated with severe complications both in the developing and adult nervous system. To investigate the deleterious effects of ZIKV infection, we used human neural progenitor cells (NPC), derived from induced pluripotent stem cells (iPSC). We found that NPC are highly susceptible to ZIKV and the infection results in(More)
BACKGROUND Galectin-3, a β-galactoside binding lectin, has been described as a mediator of cardiac fibrosis in experimental studies and as a risk factor associated with cardiovascular events in subjects with heart failure. Previous studies have evaluated the genetic susceptibility to Chagas disease in humans, including the polymorphisms of cytokine genes,(More)
Stem cells are being investigated by their potential use in regenerative medicine. There is currently a lack of effective clinical therapy for a number conditions, such as severe spinal cord injury (SCI). SCI can lead to chronic paraplegia, considered an irreversible condition. The administration of stem cells has been tested as a potential therapy for SCI.(More)
Query answering has been addressed as a key issue in distributed environments such as peer data management systems (PDMS). An important step in this process regards query routing, i.e., how to find peers (data sources) that are most likely to provide results according to the submitted query. In this process, queries are reformulated and propagated through(More)
