2. Diosmin induces caspase-dependent apoptosis in human glioblastoma cells
Abstract: Diosmin is a flavone glycoside clinically used as the main component of Daflon for the treatment of venous diseases. Several studies demonstrated that this natural compound can induce apoptosis in different tumors. However, isolated diosmin has not been studied regarding its effects on glioblastoma so far. Since glioblastoma is a highly lethal and

4. Preoperative anxiety induces chronic postoperative pain by activating astrocytes in the anterior cingulate cortex region
RESUMO OBJETIVO O objetivo deste estudo é explorar a relação entre a ansiedade no pré-operatório e a dor crônica no pós-operatório. MÉTODOS Um total de 40 ratos foram divididos em quatro grupos: controle, estresse prolongado (SPS), histerectomia e SPS + histerectomia. Os limiares de retirada da pata em resposta a estímulo mecânico (PWMT) foram

5. Memory impairments and increased GFAP expression in hippocampal astrocytes following hypercaloric diet in rats
RESUMO Objetivo: A inflamação hipotalâmica e a superexpressão da proteína glial fibrilar ácida (GFAP) em astrócitos são bem descritas em animais obesos, assim como déficits cognitivos e de memória. Como o hipocampo desempenha importante papel na consolidação de informações, esta investigação teve como objetivo observar a função da memória

6. Leukoencephalomalacia in horses associated with immature corn consumption
RESUMO: A leucoencefalomalácia dos equinos (ELEM) é uma doença causada pela ingestão de micotoxinas (fumonisinas) produzidas por fungos do gênero Fusarium que infectam o milho e/ou seus subprodutos. A doença tem sido descrita pela ingestão de milho maduro com umidade acima de 15% em temperatura ambiente abaixo de 20°C. O objetivo deste trabalho foi

7. Andrographolide protects mouse astrocytes against hypoxia injury by promoting autophagy and S100B expression
Andrographolide (ANDRO) has been studied for its immunomodulation, anti-inflammatory, and neuroprotection effects. Because brain hypoxia is the most common factor of secondary brain injury after traumatic brain injury, we studied the role and possible mechanism of ANDRO in this process using hypoxia-injured astrocytes. Mouse cortical astrocytes C8-D1A (astro

8. Neuroprotective effects of erythropoietin on rat retinas subjected to oligemia
OBJECTIVES: Erythropoietin may have neuroprotective potential after ischemia of the central nervous system. Here, we conducted a study to characterize the protective effects of erythropoietin on retinal ganglion cells and gliotic reactions in an experimentally induced oligemia model. METHODS: Rats were subjected to global oligemia by bilateral common carot

9. The protection effect and mechanism of hyperbaric oxygen therapy in rat brain with traumatic injury
Abstract Purpose: To investigate the effect of hyperbaric oxygen therapy (HBOT) on traumatic brain injury (TBI) outcome. Methods: The modified Marmarou’s weight drop device was used to generate non-lethal moderate TBI rat model, and further developed in vitro astrocytes culturing system. Then, we analyzed the expression changes of interested genes and p

10. Astrocytic expression of GFAP and serum levels of IL-1β and TNF-α in rats treated with different pain relievers
ABSTRACT Pro-inflammatory cytokines and glial cells, especially microglial cells, have been implicated in persistent pain sensitization. Less is known about the role of astrocytes in pain regulation. This study aimed to observe the expression of the astrocytic biomarker glial fibrillary acidic protein (GFAP) and the serum levels of interleukin 1 beta (IL-1β

11. Are astrocytes executive cells within the central nervous system?
ABSTRACT Experimental evidence suggests that astrocytes play a crucial role in the physiology of the central nervous system (CNS) by modulating synaptic activity and plasticity. Based on what is currently known we postulate that astrocytes are fundamental, along with neurons, for the information processing that takes place within the CNS. On the other hand,

12. PHYTOCHEMICAL ANALYSIS OF HYDROETHANOLIC EXTRACTS FROM POWDERED ROOTS OF Panax ginseng C. A. Meyer AND Heteropterys tomentosa A. Juss AND EVALUATION OF THEIR EFFECTS ON ASTROCYTE CELL DEATH
The medicinal plants Panax ginseng C. A. Meyer (Araliaceae) and Heteropterys tomentosa A. Juss (Malpighiaceae) are widely and separately used by the Brazilian population as phytotherapeutics for the same medicinal purposes as tonics and to improve cognition. A chemical analysis was carried out on hydroethanolic extracts of powdered roots from P. ginseng and
