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…
Association between apolipoprotein E epsilon4 allele and apathy in probable Alzheimer's disease.
2006
OBJECTIVE: There have been inconclusive results to date on the association between the Apolipoprotein E (ApoE) genotype and neuropsychiatric symptoms (NPS) in Alzheimer's disease (AD). We investigated whether ApoE epsilon4 allele is associated with NPS in probable AD. METHOD: Data for 197 subjects with probable AD were analysed. The Neuropsychiatric Inventory was used to evaluate the frequency and severity of NPS. Multiple logistic regression models were used to test the association between ApoE genotype and NPS in AD. RESULTS: The ApoE epsilon3/3 genotype was present in 52.3%, epsilon3/4 in 44.1%, and epsilon4/4 in 3.6% of patients. ApoE epsilon4 carriers showed a higher frequency of apath…
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…

Vascular Risk Factors in Mild Cognitive Impairment Subtypes. Findings from the ReGAl Project.
2007
Abstract Background and Aim: To investigate the role of vascular risk factors in different subtypes of mild cognitive impairment (MCI) in a multicentric, clinic-based, cross-sectional study. Methods: Two-hundred and seven subjects with MCI were included in the study: 33 with single non-memory MCI (snmMCI), 42 with multiple-domain amnestic MCI (mdMCI-a) and 132 with amnestic MCI (aMCI). Several clinical vascular risk factors and magnetic resonance imaging (MRI) brain lesions were evaluated. Results: snmMCI showed a higher frequency of ischaemic heart disease and of transient ischaemic attack (TIA)/stroke, a higher Hachinski ischaemic score and a higher frequency of white-matter lesions on MR…
Does P-glycoprotein-170 expression predict for chemoresistance in transitional cell carcinoma of the bladder?
2003
Introduction: The glycoprotein P-170, causing drug efflux from the cells, may represent at least one cause of resistance to most drugs used in intravesical chemotherapy of superficial bladder cancer. Materials and Methods: GP-170 was retrospectively assessed in 60 patients affected by superficial transitional cell tumours of the bladder. It was assessed by immunohistochemistry in a semiquantitative way by the intensity of staining and by the percentage of positive cells. Correlation of GP-170 expression with G-grade, T-category, multiplicity, recurrence rate and treatment was investigated. In 44 patients recurrence was analysed in relation to GP-170 basal expression and to its variations. T…
A novel compound heterozygous mutation in GALC associated with adult-onset Krabbe disease: case report and literature review
2021
Krabbe disease (KD) is a rare autosomal recessive lipid storage leukodystrophy. It is caused by deficient enzyme activity resulting from mutations of the β-galactocerebrosidase (GALC) gene. KD is distinguished into subtypes based on the age of onset; these are early infantile, late infantile, juvenile, and adult-onset. We report a case of a 47-year-old Caucasian man with a 2-year history of muscle atrophy and weakness in both hands associated with pyramidal signs and mild spasticity in the lower limbs. An extensive work-up led this motor neuron disease-like disorder to be diagnosed as adult-onset KD. The patient was found to be compound heterozygous for two GALC mutations (p.G286D and p.Y49…
Changes in intracortical circuits of the human motor cortex following theta burst stimulation of the lateral cerebellum
2008
Objective: The cerebellum takes part in several motor functions through its influence on the motor cortex (M1). Here, we applied the theta burst stimulation (TBS) protocol, a novel form of repetitive Transcranial Magnetic Stimulation (rTMS) over the lateral cerebellum. The aim of this study was to test whether TBS of the lateral cerebellum could be able to modulate the excitability of the contralateral M1 in healthy subjects. Methods: Motor-evoked potentials (MEPs) amplitude, short intracortical inhibition (SICI), long intracortical inhibition (LICI) and short intracortical facilitation (SICF) were tested in the M1 before and after cerebellar continuous TBS (cTBS) or intermittent TBS (iTBS)…
The default mode network and the working memory network are not anti-correlated during all phases of a working memory task
2015
INTRODUCTION:\ud \ud The default mode network and the working memory network are known to be anti-correlated during sustained cognitive processing, in a load-dependent manner. We hypothesized that functional connectivity among nodes of the two networks could be dynamically modulated by task phases across time.\ud METHODS:\ud \ud To address the dynamic links between default mode network and the working memory network, we used a delayed visuo-spatial working memory paradigm, which allowed us to separate three different phases of working memory (encoding, maintenance, and retrieval), and analyzed the functional connectivity during each phase within and between the default mode network and the …
