C9ORF72 in a Large Series of Italian and Sardinian Familial and Sporadic ALS Patients (IN9-1.003)

2012

Objective: To assess the frequency and the phenotype of a large series of Italian sALS and fALS with C9ORF72 repeat expansions. Background Recently we found that large expansions of hexanucleotide repeats (GGGGCC) in the first intron of the C9ORF72 gene, located in the chromosome 9p21, are related to familial and sporadic ALS cases(Renton et al, 2011). Design/Methods: We assessed 126 index fALS (106 Italians, 20 of Sardinians) and 601 sALS (485 Italians, 116 Sardinians), negative for other ALS-related genes mutations. Patients were collected through the ITALSGEN consortium. Repeat primer PCR to screen the presence of the hexanucleotide expansion in the first intron of C9ORF72 have been perf…

Chapter 15 Pain and itch in Wallenberg's syndrome: anatomical–functional correlations

2006

Publisher Summary The Wallenberg syndrome or dorso-lateral medullary infarction is the most common vascular syndrome of the medulla oblongata. Its clinical features include an ipsilateral Horner's syndrome, an ipsilateral limb ataxia, and mostly an ipsilateral but sometimes also a contralateral or bilateral decrease of pain and temperature sensibility of the face. Patients with Wallenberg's syndrome and with morphological (lesion) or functional (ipsilateral sensory deficit and delayed late blink reflex responses) show evidence of damage to the trigeminal tract and nucleus with sparing of the nucleus caudalis would develop facial pain. The trigeminal trophic syndrome (TTS), a very rare compl…

Dietary Patterns and Healthy Ageing

2021

Ageing is a complex process in which multiple factors are involved that can contribute to determine whether a person will or not be affected by diseases that are more frequently observed in advanced age. The factors involved comprise genetic, environmental, behavioural, and dietary factors, which influence pathways that regulate the ageing process and the life expectancy, rendering longevity a multifaceted phenomenon. Even if a miraculous elixir or pill is not yet available, there is general agreement that nutrition has a major impact on the overall mortality and on the development of age-related chronic non-communicable diseases. Nutrition research has focused for decades on single nutrien…

Cellular Acetylcholine Receptor Expression in the Brain of Patients with Alzheimer’s and Parkinson’s Dementia

1995

Binding studies and receptor autoradiography reveal the overall changes of acetylcholine receptors (AChR) in Alzheimer’s and Parkinson’s dementia cortices.2,5 A detailed account of these changes requires a study of neurochemical phenotype of individual neurons as basic elements of networks constituting the substrate of cortical functions.4 Examples will be given for cell-type specific AChR localization in normal and diseased human cerebral cortex.

Modeling of 137Cs migration in soils using an 80-year soil archive: role of fertilizers and agricultural amendments

2008

An 80-year soil archive, the 42-plot experimental design at the INRA in Versailles (France), is used here to study long-term contamination by 137Cs atmospheric deposition and the fate of this radioisotope when associated with various agricultural practices: fallow land, KCl, NH4(NO3), superphosphate fertilizers, horse manure and lime amendments. The pertinence of a simple box model, where radiocaesium is supposed to move downward by convectional mechanisms, is checked using samples from control plots which had been neither amended, nor cultivated since 1928. This simple model presents the advantage of depending on only two parameters: α, a proportional factor allowing the historical atmosph…

The Mental Health of Caregivers and Their Patients With Dementia During the COVID-19 Pandemic: A Systematic Review

2021

Background: Coronavirus Disease 2019 (COVID-19) is a worldwide public health concern. It continues to spread rapidly throughout the world causing multiple physical and psychological consequences in the population. Especially, people affected by severe psychiatric or neurological diseases are highly susceptible to serious health complications not only due to the direct effect of the infection but also to the indirect effect of COVID-19 following social distancing during lockdowns and its general social consequences. Indeed, lockdown and difficulties in using the care services produced psychological consequences in caregivers such as depression, anxiety, and worsening of the quality of life w…

Potential Roles of Peroxisomes in Alzheimer's Disease and in Dementia of the Alzheimer's Type

2012

In Alzheimer's disease (AD) and dementia of the Alzheimer's type (DAT), the role played by peroxisomes is not well known. Peroxisomes are present in all eukaryotic cells, with the exception of erythrocytes. They are involved in the β-oxidation process of long-chain fatty acids, very-long-chain fatty acids, and branched-chain fatty acids. They participate in the α-oxidation of phytanic acid, the biosynthesis of bile acids, and the breakdown of eicosanoids. Peroxisomes are also involved in the synthesis of specific fatty acids such as docosahexaenoic acid (DHA), which is essential for the brain and retina, and plasmalogens (PLGN), which play crucial roles in neural cells and are essential com…

A Radical Signal Activates the Epigenetic Regulation of Longevity

2013

Hormesis is an adaptive stress response implicated in longevity regulation. Schroeder et al. (2013) have now connected stress, epigenetic changes, and aging in yeast by showing that mitochondria-derived reactive oxygen species modulate the chromatin binding capacity of the histone demethylase Rph1p at subtelomeres, resulting in lifespan extension.
