Hyperhomocysteinemia can result from decreased methylenetetrahydrofolate reductase (MTHFR) enzyme activity, owing to genetic polymorphisms andor inadequate folate intake. This study was aimed at investigating the prevalence of C677T and A1298C MTHFR polymorphisms, and their impact on hyperhomocysteinemia in 95 epileptic patients and 98 controls. Double(More)
Agmatine, an endogenous arginine metabolite, has been proposed as a novel neuromodulator that plays protective roles in the CNS in several models of cellular damage. However, the mechanisms involved in these protective effects in neurodegenerative diseases are poorly understood. The present study was undertaken to investigate the effects of agmatine on cell(More)
Transglutaminase 2 (TG2) is a multifunctional calcium-dependent enzyme which catalyzes the post-translational protein crosslinking with formation of intra- or inter-molecular epsilon(gamma-glutamyl)lysine bonds or polyamine incorporation. The up-regulation and activation of TG2 have been reported in a variety of physiological events, including cell(More)
Agmatine is a novel neuromodulator that plays a protective role in the CNS in several models of cellular damage. However, the mechanisms involved in these protective effects in neurodegenerative diseases are poorly understood. Fourier transform infrared (FTIR) spectroscopy analysis detects biomolecular changes in disordered cells and tissues. In this(More)
Zonisamide (ZNS), an antiepileptic drug having beneficial effects also against Parkinson’s disease symptoms, has proven to display an antioxidant effects in different experimental models. In the present study, the effects of ZNS on rotenone-induced cell injury were investigated in human neuroblastoma SH-SY5Y cells differentiated towards a neuronal(More)
OBJECTIVE To document the relationship between neurocognitive recovery and macronutrient intake of patients suffering from ischemic strokes. DESIGN Thirty day prospective study of 17 patients suffering from sub-acute stroke (> 14 days from the index event; 10 males, 7 females; mean age 75 +/- 8 years) admitted to our rehabilitation unit. RESULTS At(More)
The presence and severity of cerebrovascular pathological findings have been shown to increase the risk and stage of cognitive decline observed in Alzheimer's disease and vascular dementia. Thus, the modification of vascular risk factors seems useful to reduce the risk of dementia regardless of type. Hyperhomocysteinemia has long been known as a major(More)
Several experimental approaches have demonstrated that transglutaminase 2 (TG2) increased activity is involved in monocyte activation and inflammatory response. Preliminary results also demonstrate a TG-mediated post-translational modification of phospholipase A2 (PLA2), which catalyzes the release of arachidonic acid from its lipid storage sites. The(More)
Transglutaminase 2 has been postulated to be involved in the pathogenesis of central nervous system neurodegenerative disorders. However, its role in neuronal cell death remains to be elucidated. Excitotoxicity is a common event underlying neurodegeneration. We aimed to evaluate the protein targets for transglutaminase 2 in cell response to NMDA-induced(More)
BACKGROUND Perinatal exposure to hyperhomocysteinemia might disturb neurogenesis during brain development and growth. Also, high levels of homocysteine trigger neurodegeneration in several experimental models. However, the putative mechanisms of homocysteine-induced toxicity in the developing nervous system have poorly been elucidated. This study was aimed(More)
