Autogenous cancellous bone is considered to be the best bone grafting material. Autogenous bone grafts provide scaffolding for osteoconduction, growth factors for osteoinduction, and progenitor stem cells for osteogenesis. However, the procurement morbidity, limited availability, and expense associated with the use of autogenous bone grafts are significant(More)
BACKGROUND Oxidative stress and neuronal cell death have been implicated in the pathogenesis of Alzheimer disease (AD). Considering that the glutathione transferase (GST) supergene family encodes isoenzymes that appear to be critical in protection against oxidative stress, we aimed at determining the various GSTP1, GSTM1, and GSTT1 polymorphisms and ApoE(More)
BACKGROUND AND AIM Inflammation has been extensively implicated in the pathogenesis of Alzheimer's disease (AD). Although there is evidence of a key role for cytokines in neuroinflammation processes, so far the proinflammatory cytokine interleukin (IL)-18 has not been associated with AD. The aim of this study was to investigate the impact of two(More)
OBJECTIVE Oxidative stress has been suggested as a contributor of Alzheimer disease (AD) neurodegeneration, particularly in those patients with late-onset AD (LOAD). Therefore, the authors studied the effect of glutathione S-transferase (GST) P1-M1-T1 gene polymorphisms and their interactions with the apolipoprotein E (ApoE) epsilon4 allelic variant on the(More)
Current clinical practice considers antinuclear antibody (ANA) testing as a screening test; this has a major impact on laboratory work with a growing volume of analyses that need to be performed rapidly, to maintain good specificity and sensitivity. Ongoing discussions have been raised in order to identify the best technology to use in ANA screening, taking(More)
The oxidative stress could have a dual action on glutathione S-transferase (GST) P1-1 metabolism: transcriptional induction and/or polymerization. The former should represent a form of adaptation to oxidative stress and contribute to protect the cell, the latter one should activate apoptosis via c-Jun N-terminal kinase (JNK). We studied the effect of(More)
BACKGROUND The apolipoprotein E (apo E) polymorphism is associated with the risk of developing cardiovascular disease and the risk and the time of onset of Alzheimer's disease. Therefore, the interest in apo E genotyping is high, both for epidemiological research and for the purpose of diagnosing dyslipidemia or dementia. The aim of our study was to compare(More)
Although the etiology of psychotic symptoms (hallucinations and delusions) in Alzheimer's disease is still not known, alterations in serotonergic neurotransmission have been proposed. In a 3-year follow-up study, we evaluated the association of serotonin (5-HT) receptor 5-HT2a 102T/C polymorphism (allelic variants CC, CT and TT) with psychotic symptom(More)
Physiologically, the action of insulin-like growth factors (IGFs) is controlled at different levels, from its transcription start by tissue-specific and development-specific transcriptional factors to its degradation by peptidases such as insulin-degrading enzyme (IDE). Since IGF-II is the major autocrine/paracrine growth factor for neuroblastoma cells, we(More)
We examined the effect of paclitaxel on human osteoblastic cells Saos-2 to determine if paclitaxel can affect proliferation and apoptosis. We used a p53-negative cell line in order to mimic the loss of function frequently observed at the clinical level. Paclitaxel induced cell death in a dose- and time-dependent manner. Marked nuclear condensation and(More)
