Acute liver injury was induced in male BALB/c mice by coadministering isoniazid and rifampicin. In this work, the effects of resveratrol (1) were investigated in the hepatotoxicity caused by isoniazid-rifampicin in mice. Compound 1 was administered 30 min prior to isoniazid-rifampicin. Serum biochemical tests, liver histopathological examination, oxidative(More)
Gliomas are the most common malignant brain tumors in adults. Bradykinin (BK) displays an important role in cancer, although the exact role of kinin receptors in the glioma biology remains unclear. This study investigated the role of kinin B1 and B2 receptors (B1R and B2R) on cell proliferation in human glioblastoma cell lineages. The mRNA expression of B1R(More)
Oxaliplatin (OXA) is a platinum compound widely used in the treatment of some solid tumors, especially colorectal cancer. Despite its usefulness, oxaliplatin-associated neurotoxicity represents the main dose-limiting factor of this drug, and until now, there is no suitable treatment. Chemotherapy with oxaliplatin also increases the rate of developing(More)
Glioblastoma multiforme (GBM) is considered the most lethal intracranial tumor and the median survival time is approximately 14 months. Although some glioma cells present radioresistance, radiotherapy has been the mainstay of therapy for patients with malignant glioma. The activation of P2X7 receptor (P2X7R) is responsible for ATP-induced death in various(More)
Good sleep is an important index of the quality of life in people and above all in old subjects. Among all the symptoms reported to general practitioner, insomnia is at the 3(rd) place and this is present in particular in the elderly. In elderly people high comorbidity and polytreatment are often present. We have studied 60 elderly people with history of(More)
Malignant brain tumors are highly lethal and aggressive. Despite recent advances in the current therapies, which include the combination of surgery and radio/chemotherapy, the average survival rate remains poor. Altered regulation of ion channels is part of the neoplastic transformation, which suggests that ion channels are involved in cancer. Distinct(More)
This study investigated the effects of the long-term dietary fish oil supplementation or the acute administration of the omega-3 fatty acid docosahexaenoic acid (DHA) in the mouse hemorrhagic cystitis (HC) induced by the anticancer drug cyclophosphamide (CYP). HC was induced in mice by a single CYP injection (300mg/kg ip). Animals received four different(More)
The objective of this study is to demonstrate that the finite element method can be used to model tensioning in circular sawblades. The finite element analysis is used to determine the residual stresses in the blade; the introduction of these stresses into a modal analysis allows us to predict the dynamic behavior (natural frequencies and critical speed) of(More)
Trichomonal infestation has spread in every continent, in every class, in every race and climate. It may be asked whether this is due to the misfortunes of war or to improved methods of detecting the organism. Does it affect the vagina or the whole uro-genital system? Is it acquired and transmitted solely by sexual contact? What are the different forms of(More)
OBJECTIVE Mitogen-activated protein kinase (MAPK) p38 inhibitors have entered the clinical phase, although many of them have failed due to high toxicity and lack of efficacy. In the present study we compared the effects of the selective p38 inhibitor ML3403 and the dual p38-PDE4 inhibitor CBS-3595, on inflammatory and nociceptive parameters in a model of(More)
