The nutrigenetic influence of the interaction between dietary vitamin E and TXN and COMT gene polymorphisms on waist circumference: a case control st…

2015

Background Abdominal obesity (AO) is a common modifiable risk factor for certain non-communicable diseases associated with enhanced oxidative stress (OS). The objective of this work was to investigate whether the interaction between antioxidant vitamin intake and OS-related polymorphisms modulates gene-associated anthropometry in a Spanish population. Methods A total of 246 subjects with AO, and 492 age and gender matched non-AO subjects were included in the study. Anthropometric, biochemical, and OS parameters, and antioxidant dietary intake data were assessed using validated procedures. DNA from white blood cells was isolated and the genotype of seven polymorphisms from genes involved in …

Oxidative stress in patients with Alzheimer's disease: Effect of extracts of fermented papaya powder

2015

Brain tissue is particularly susceptible to oxidative stress (OS). Increased production of reactive oxygen species (ROS), reduced antioxidant systems, and decreased efficiency in repairing mechanisms have been linked to Alzheimer’s disease (AD). Postmortem studies in AD patients’ brains have shown oxidative damage markers (i.e., lipid peroxidation, protein oxidative damage, and glycoxidation). Fermented papaya (FPP, a product ofCarica papaya Linnfermentation with yeast) is a nutraceutical supplement with favorable effects on immunological, hematological, inflammatory, and OS parameters in chronic/degenerative diseases. We studied 40 patients (age 78.2 ± 1.1 years), 28 AD patients, and 12 co…

Thoracic Aortic Intima-Media Thickness in Preschool Children Born Small for Gestational Age

2018

To assess thoracic aortic intima-media thickness (aIMT) as a marker of thoracic aortic remodeling in children born small for gestational age (SGA).We assessed thoracic aIMT, carotid intima-media thickness (cIMT), and pulse wave velocity (PWV) in 239 patients (117 SGA; 122 appropriate for gestational age controls) age 6-8 years. Each SGA participant was matched 1:1 based on sex, gestational age, and birth date. Thoracic aIMT was determined by 2-dimensional transthoracic echocardiography.SGA children showed a significant increase in both aIMT (0.89 mm [0.12] vs 0.79 mm [0.11], P  .001) and cIMT (.50 mm [0.05] vs 0.49 mm [0.04], P  .001) compared with appropriate for gestational age controls, …

Lack of association between angiotensin converting enzyme polymorphism and sporadic Alzheimer's disease

2002

Epidemiological and pathogenetic evidences suggest a strong association between vascular risk factors and sporadic Alzheimer's disease (sAD). In agreement with the vascular hypothesis of AD, the role of various candidate genes for atherosclerosis has been investigated, leading to conflicting results. In order to clarify the significance of angiotensin-converting enzyme (ACE) gene insertion (I)/deletion (D) polymorphism in a group of patients with sAD, we conducted a case-control study including 149 cases and 149 age and sex matched controls. All subjects were genotyped for ACE and Apolipoprotein E (APOE). There were no significant differences in ACE genotype or allele frequencies between ca…

No association between the cystatin C gene polymorphism and Alzheimer's disease: a case-control study in an Italian population.

2005

Cystatin C is an amyloidogenic protein found together with beta-amyloid in cerebral arteriolar walls of both patients with Alzheimer's Disease (AD) and conghopilic amyloid angiopathy. Several findings implicate cystatin C in the pathogenesis of vascular diseases. Recent genetic association studies proposed cystatin C gene (CST3) as a susceptibility factor for AD, although other reports did not replicate this finding. We conducted a case-control study including 192 probable AD cases and 192 age- and sex-matched controls to test the association between CST3 and AD. Possible interaction between CST3 and age at onset of AD or apolipoprotein E (APOE) was also examined. No significant differences…

Association of estrogen receptor α gene with Alzheimer's disease: A case-control study

2006

Abstract Recent experimental data have offered the biological background to study the estrogen receptor (ER) alpha gene as a candidate gene for AD. Genetic association studies proposed ERalpha PvuII and XbaI gene polymorphisms as susceptibility factors for AD, although subsequent studies did not replicate this finding. To verify this association in a Caucasian Italian sample, we conducted a case-control study in a dataset of 172 clinic-based probable AD cases and 172 age- and sex-matched controls. Possible interaction between ERalpha polymorphisms and sex, age at onset of AD or apolipoprotein E (APOE) was examined. The xx-genotype of the XbaI polymorphism was associated with the risk of dev…

Meta-analysis of 74,046 individuals identifies 11 new susceptibility loci for Alzheimer's disease

2013

Eleven susceptibility loci for late-onset Alzheimer's disease (LOAD) were identified by previous studies; however, a large portion of the genetic risk for this disease remains unexplained. We conducted a large, two-stage meta-analysis of genome-wide association studies (GWAS) in individuals of European ancestry. In stage 1, we used genotyped and imputed data (7,055,881 SNPs) to perform meta-analysis on 4 previously published GWAS data sets consisting of 17,008 Alzheimer's disease cases and 37,154 controls. In stage 2, 11,632 SNPs were genotyped and tested for association in an independent set of 8,572 Alzheimer's disease cases and 11,312 controls. In addition to the APOE locu…

Apoe genotypes and brain imaging classes in normal cognition, mild cognitive impairment, and alzheimer’s disease: A longitudinal study

2020

Objective: To evaluate in 419 stroke-free cognitively normal subjects (CN) aged 45-82 years covering during a long prospective study (11.54 ± 1.47 years) the preclinical to dementia spectrum: 1) the distribution of small vessel disease (V) and brain atrophy (A) aggregated as following: V−/A−, V−/A+, V+/A−, V+/A+; 2) the relationship of these imaging classes with individual apolipoprotein E (APOE) genotypes; 3) the risk of progression to Alzheimer Disease (AD) of the individual APOE genotypes. Methods: Participants underwent one baseline (t0), and 4 clinical and neuropsychological assessments (t1,t2,t3, and t4). Brain MRI was performed in all subjects at t0, t2, t3 and t4..

CD14+CD16+ monocytes in coronary artery disease and their relationship to serum TNF-α levels

2004

SummaryMonocytes play a central role in the inflammatory disease atherosclerosis. CD14+CD16+ monocytes are considered proinflammatory monocytes, as they have an increased capacity to produce proinflammatory cytokines, such as TNF-α, and are elevated in various inflammatory diseases. We hypothesized that patients with coronary artery disease (CAD) have increased levels of CD14+CD16+ monocytes, and that CD14+CD16+ monocytes are associated with inflammation markers. We investigated CD14+CD16+ monocytes in 247 patients with CAD and 61 control subjects using flow cytometry. In addition serum concentrations of TNF-α, IL-6, and Hs-CRP were assessed. Patients with CAD had higher levels of CD14+CD16…
