Amyotrophic lateral sclerosis is a degenerative disorder of motor neurons that typically develops in the 6th decade and is uniformly fatal, usually within 5 years. To identify genetic variants associated with susceptibility and phenotypes in sporadic ALS, we performed a genome-wide SNP analysis in sporadic ALS cases and controls. A total of 288,357 SNPs(More)
Amyotrophic lateral sclerosis (ALS) is a progressive, neurodegenerative disorder of upper and lower motor neurons. Genetic variants in the paraoxonase gene cluster have been associated with susceptibility to sporadic ALS. Because these studies have yielded conflicting results, we have further investigated this association in a larger data set. Twenty SNPs(More)
Three clustered, homologous paraoxonase genes (PON1, PON2, and PON3) have roles in preventing lipid oxidation and detoxifying organophosphates. Recent reports describe a genetic association between the PON genes and sporadic amyotrophic lateral sclerosis (ALS). We now report that in genomic DNA from individuals with familial and sporadic ALS, we have(More)
BACKGROUND AND STUDY AIMS Spontaneous intracerebral hemorrhage (ICH) represents the most fatal kind of stroke, and there is still no treatment available that improves the outcome. Statins are cholesterol reducers, and during the last few years many additional effects have been demonstrated that might be neuroprotective. We designed a pilot clinical study in(More)
PURPOSE To assess the multiple-dose pharmacokinetics of levetiracetam and its major metabolite ucb L057 in children with partial-onset seizures and determine whether it is affected by adjunctive carbamazepine or valproate. To correlate levetiracetam concentrations in plasma and saliva and to assess its safety and clinical response. METHODS Design was an(More)
INTRODUCTION The spontaneous intracerebral hemorrhage (ICH) shows a high lethal rate. In 1999 appeared the first therapeutic guidelines, after that new therapies have been assessed without substantial success. AIM To describe treatment changes for ICH in a regional Mexican hospital and to assess their impact on clinical evolution. PATIENTS AND METHODS(More)
OBJECTIVE The presence in the brain of α-synuclein containing Lewy neurites, or bodies, is the histological hallmark of Parkinson's disease (PD). The discovery of α-synuclein aggregates in nerve endings of the heart, digestive tract, and skin has lent support to the concept of PD as a systemic disease. Our goals were, first, to demonstrate the presence of(More)
INTRODUCTION The 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA) inhibitors or statins are drugs used in the treatment of dyslipidemies. The clinical trials performed for evaluation of the efficacy observed a reduced incidence of stroke and other trials have demonstrated a better outcome after stroke and subrachnoid hemorrhage. DEVELOPMENT In(More)
Raman spectroscopy of biological tissue presents fluorescence background, an undesirable effect that generates false Raman intensities. This paper proposes the application of the Empirical Mode Decomposition (EMD) method to baseline correction. EMD is a suitable approach since it is an adaptive signal processing method for nonlinear and non-stationary(More)
INTRODUCTION Intracerebral hemorrhage (ICH) is the most lethal type of stroke. There are some clinical and radiological factors related to mortality. The time for obtaining medical care could be related with poor prognosis, but there are not available studies in Hispanics that evaluated this one. AIM To determinate the association between epidemiological(More)
