The contribution of oligodendrocytes and oligodendrocyte progenitor cells to central nervous system repair in multiple sclerosis： perspectives for remyelination therapeutic strategies

引用

Neural Regeneration Research 2017年第12期12卷 1939-1944页

作者： adriana Octaviana Dulamea Department of Neurology Fundeni Clinical Institute University of Medicine and Pharmacy "Carol Davila" Bucharest Romania

Oligodencrocytes（OLs） are the main glial cells of the central nervous system involved in myelination of axons. In multiple sclerosis（MS）, there is an imbalance between demyelination and remyelination processes, the last one performed by oligodendrocyte progenitor cells（OPCs） and OLs, resulting into a permanent demyelination, axonal damage and neuronal loss. In MS lesions, astrocytes and microglias play an important part in permeabilization of blood-brain barrier and initiation of OPCs proliferation. Migration and differentiation of OPCs are influenced by various factors and the process is finalized by insufficient acummulation of OLs into the MS lesion. In relation to all these processes, the author will discuss the potential targets for remyelination strategies.

INFLUENCE OF RARE EARTH DOPING ON MECHANICAL PROPERTY AND MICRO-STRUCTURE OF CHROMIA OXIDE FILM

引用

Chinese Journal of Mechanical Engineering 2008年第3期21卷 16-19页

作者： JIN Huiming FELIX adriana College of Mechanical Engineering Yangzhou University Yangzhou 225005 China College of Materials Engineenng National University of Antiuquia Medellin 23715 Colombia

The isothermal oxidizing kinetics of Co-40Cr alloy and its yttrium ion-implanted samples are studied at 1 000 ℃ in air by thermal-gravity analysis （TGA）. Scanning electronic microscopy （SEM） is used to examine the Cr2O3 oxide film＇s morphology after oxidation. Acoustic emission （AE） method is used in situ for monitoring the cracking and spalling of oxide films formed on both samples during oxidizing and subsequent air-cooling stages. Theoretical model is proposed relating to the film fracture process and is used for analyzing the acoustic emission spectrum both on time domain and on AE-event number domain. It is found that yttrium implantation remarkably reduces the isothermal oxidizing rate of Co-40Cr and improves the anti-cracking and anti-spalling properties of Cr2O3 oxide film. The reasons for the improvement are mainly that the implanted yttrium reduced the grain size of Cr2O3 oxide, increased the high temperature plasticity of oxide film, and remarkably reduced the number and size of Cr2O3/Co-40Cr inteffacial defects.

Blood group type antigens in pancreatic intraductal papillary mucinous neoplasms

引用

Hepatobiliary & Pancreatic Diseases International 2014年第1期13卷 74-80页

作者： adriana Handra-Luca Departments of Pathology Sydney Kimmel Comprehensive Cancer Center Johns Hopkins Medical Institutions APHP Universite Paris Nord Sorbonne Cite-Sce Anatomie Pathologique GHU Avicenne 125 rue Stalingrad Bobigny 93000 France

BACKGROUND: There are few data on blood group(BG) types and types of pancreatic cancers. The aims of this study were to study BG types and BG-antigens in pancreatic intraductal papillary mucinous neoplasms(IPMNs). METHODS: BG type and tumor BG-antigen(glycoprotein) expression(studied by immunohistochemistry on tissue microarrays) were analyzed with regard to characteristics of 101 surgically resected pancreatic IPMNs. RESULTS: Non-O BG type predicted invasive carcinoma independently from high serum CA19-9 and male gender. BG type A was observed more frequently in women than in men. Chronic pancreatitis was more frequently seen in patients with BG type B or AB. Aberrant tumor expression(with regard to BG type) of loss of A antigen expression type occurred in 15.0% of IPMNs and of loss of B antigen expression type in 62.5% of IPMNs. Intraneoplasm BG-antigen expression was not related to dysplasia grade or invasion. CONCLUSION: The results of the study suggest that in pancreatic IPMN, non-O BG type predicted invasive carcinoma, whereas for intratumor BG-antigen expression no specific patterns were detected with regard to the progression of glandular epithelial dysplasia or invasion.

Biomimetic Control of Mechanical Systems Equipped with Musculotendon Actuators

引用

Journal of Bionic Engineering 2011年第1期8卷 56-68页

作者： Javicr Moreno-Valenzuel adriana Salinas-Avila Instituto Politecnico Naoional-CITEDl Av. del Parque 1310 Mesa de Otay Tianjuana B.C. 22510 Mexico

This paper addresses the problem of modelling, control, and simulation of a mechanical system actuated by an agonist-antagonist musculotendon subsystem. Contraction dynamics is given by case 1 of Zajac＇s model. Saturated semi positive proportional-derivative-type controllers with switching as neural excitation inputs are proposed. Stability theory of switched system and SOSTOOLS, which is a sum of squares optimization toolbox of Matlab, are used to determine the stability of the obtained closed-loop system. To corroborate the obtained theoretical results numerical simulations are carried out. As additional contribution, the discussed ideas are applied to the biomimetic control of a DC motor, i.e., the position control is addressed assuming the presence of musculotendon actuators. Real-experiments corroborate the expected results.

Dendrite pathology and neurodegeneration:focus on m TOR

引用

Neural Regeneration Research 2015年第4期10卷 559-561页

作者： adriana Di Polo Department of Neuroscience and Centre de recherche du Centre hospitalier de l’Université de Montréal (CRCHUM) University of Montreal

Dendrites are exquisitely specialized cellular compart- ments that critically influence how neurons receive and process information. Most synaptic inputs are received onto dendritic shafts, or small protuberances known as dendritic spines, and are then integrated and transmitted to the cell soma. During nervous system development, dendrites are dynamic, expanding and retracting rapidly, in response to intrinsic and environmental cues. Selective elimination of dendritic processes, also known as developmental pruning, ensures precise connectivity and refines neuronal networks.
