13. Systemic dissemination of glioblastoma: literature review
RESUMO INTRODUÇÃO: Glioblastoma (GBM) é o tumor maligno mais comum do sistema nervoso central em adultos. Entretanto, metástase a distância de GBM é um evento extremamente raro. O presente estudo teve o objetivo de realizar uma revisão da literatura para avaliar os possíveis mecanismos biológicos relacionados com a ocorrência de metástase a dist�

14. Metastasis from glioblastoma multiforme: a meta-analysis
RESUMO OBJETIVO: Metástases extracranianas do glioblastoma multiforme (GBM) são raras devido à baixa sobrevida dos pacientes. Portanto, a história natural das metástases do GBM permanece incerta. A identificação de fatores clínicos que promovem metástases no GBM pode ajudar a elucidar os mecanismos de invasão das células tumorais no cérebro. O o

15. Effects of lithium on inflammatory and neurotrophic factors after an immune challenge in a lisdexamfetamine animal model of mania
Objective: To evaluate whether an animal model of mania induced by lisdexamfetamine dimesylate (LDX) has an inflammatory profile and whether immune activation by lipopolysaccharides (LPS) has a cumulative effect on subsequent stimuli in this model. We also evaluated the action of lithium (Li) on inflammatory and neurotrophic factors. Methods: Adult male Wi

16. Evaluation of the antioxidant potential of Copaifera multijuga in Ehrlich tumor-bearing mice
RESUMO Copaifera multijuga, ou copaíba, é utilizada popularmente como chá para o tratamento de diversas afecções, o que se deve à presença de substâncias antioxidantes em sua composição, que protegem as células contra danos causados pelos radicais livres. O óleo-resina da árvore é usado como antiinflamatório e antitumoral. O presente estudo av

17. Identification of microRNA signature in different pediatric brain tumors
Abstract Understanding pediatric brain tumor biology is essential to help on disease stratification, and to find novel markers for early diagnosis. MicroRNA (miRNA) expression has been linked to clinical outcomes and tumor biology. Here, we aimed to detect the expression of different miRNAs in different pediatric brain tumor subtypes to discover biomarkers f

18. Inflammatory biomarkers responses after acute whole body vibration in fibromyalgia
The aims of this study were 1) to characterize the intensity of the vibration stimulation in women diagnosed with fibromyalgia (FM) compared to a control group of healthy women (HW) matched by age and anthropometric parameters, and 2) to investigate the effect of a single session of whole body vibration (WBV) on inflammatory responses. Levels of adipokines,

19. Bevacizumab and gefitinib enhanced whole-brain radiation therapy for brain metastases due to non-small-cell lung cancer
Non-small-cell lung cancer (NSCLC) patients who experience brain metastases are usually associated with poor prognostic outcomes. This retrospective study proposed to assess whether bevacizumab or gefitinib can be used to improve the effectiveness of whole brain radiotherapy (WBRT) in managing patients with brain metastases. A total of 218 NSCLC patients wit

20. Cryptococcoma mimicking a brain tumor in an immunocompetent patient: case report of an extremely rare presentation
ABSTRACT CONTEXT: Central nervous system (CNS) infectious diseases have high prevalence in developing countries and their proper diagnosis and treatment are very important for public health planning. Cryptococcus neoformans is a fungus that may cause several CNS manifestations, especially in immunocompromised patients. Cryptococcal meningitis is the most co

21. Candesartan, rather than losartan, improves motor dysfunction in thioacetamide-induced chronic liver failure in rats
Minimal hepatic encephalopathy is more common than the acute syndrome. Losartan, the first angiotensin-II receptor blocker (ARB), and candesartan, another widely-used ARB, have protected against developing fibrogenesis, but there is no clear data about their curative antifibrotic effects. The current study was designed to examine their effects in an already-

22. Pattern recognition of abscesses and brain tumors through MR spectroscopy: Comparison of experimental conditions and radiological findings
Abstract Introduction The interpretation of brain tumors and abscesses MR spectra is complex and subjective. In clinical practice, different experimental conditions such as field strength or echo time (TE) reveal different metabolite information. Our study aims to show in which scenarios magnetic resonance spectroscopy can differentiate among brain tumors,

23. Bee venom induces apoptosis and suppresses matrix metaloprotease-2 expression in human glioblastoma cells
Abstract Glioblastoma is the most common malignant brain tumor representing with poor prognosis, therapy resistance and high metastasis rate. Increased expression and activity of matrix metalloproteinase-2, a member of matrix metalloproteinase family proteins, has been reported in many cancers including glioblastoma. Inhibition of matrix metalloproteinase-2

24. 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
