When Does Alzheimer′s Disease Really Start? The Role of Biomarkers

2021

While Alzheimer’s disease (AD) classical diagnostic criteria rely on clinical data from a stablished symptomatic disease, newer criteria aim to identify the disease in its earlier stages. For that, they incorporated the use of AD’s specific biomarkers to reach a diagnosis, including the identification of Aβ and tau depositions, glucose hypometabolism, and cerebral atrophy. These biomarkers created a new concept of the disease, in which AD’s main pathological processes have already taken place decades before we can clinically diagnose the first symptoms. Therefore, AD is now considered a dynamic disease with a gradual progression, and dementia is its final stage. With …

Trends in Microbiology publications: are classic scientific journals condemned to extinction?

2020

ABSTRACT Scientific journals have played an essential role in the diffusion of research breakthroughs. For many years there was no competition between journals, but, in recent decades they have become categorized by a careful assessment of their published contents based on several metric parameters. Of greater note, the ‘prestige index’ has become an essential tool used by public and private institutions to develop their scientific policy. Thus, the evaluation of research staffs, the concession of grants or fellowships and even the scholarly reputation and academic positions are mainly founded on a given journal's ‘quality’. As a consequence, the prestige of some journals has gone up, based…

Localización e identificación de las revistas universitarias para su integración en repositorios institucionales. El caso de la Universitat de Valènc…

[EN] Objectives. Prior to starting up the University of Valencia's (UV) institutional repository, we assessed this institution's real output of periodical publications and drew up the most comprehensive list possible. We also described the visibility of the contents on the Internet. -- Method. We searched the ISSN database and the UV's library catalogue for journals in which the UV is included in the statement of responsibility. -- Results. These two sources did not provide sufficient information, as the University was not listed in all the relevant journals as a publishing entity. In total, 162 journals were found, of which 34.6% are still published. Many have been out of print since the 1…

Regulation of the neutralizing anti-hepatitis B surface (HBs) antibody response in vitro in HBs vaccine recipients and patients with acute or chronic…

1996

Abstract Antibodies directed to the HBs antigen indicate viral clearance and the development of life-long immunity in patients that recovered from HBV infection. In HBs antigen vaccine recipients anti-HBs antibodies provide protective immunity. However, little is known about the regulation of this HBs-specific antibody response. The existence of anti-HBs-secreting B cells was demonstrated using the highly sensitive ELISPOT technique compared with conventional ELISA in serum and cell culture supernatants. In the peripheral blood of patients with acute self-limited hepatitis B, HBs-specific B cells were demonstrated with a high frequency despite undetectable anti-HBs serum antibodies. HBV-imm…

Bibliometric analysis of publications by South African viticulture and oenology research centres

2012

We analysed the production, impact factor of, and scientific collaboration involved in viticulture and oenology articles associated with South African research centres published in international journals during the period 1990–2009. The articles under scrutiny were obtained from the Science Citation Index database, accessed via the Web of Knowledge platform. The search strategy employed specific viticulture and oenology terms and was restricted to the field ‘topic’. The results showed that 406 articles were published during the review period, with the most number of publications being in the South African Journal of Enology and Viticulture (n = 34), American Journal of Enology and Vit…

Algunas reflexiones acerca de la stjue de 9 de julio de 2020 sobre los pactos novatorios en materia de cláusulas suelo

2021

The Sentence of the Court of Justice of the European Union of July 9, 2020 comes to answer the five questions that, in its preliminary question, the Court of First Instance and Instruction No. 3 of Teruel asks about the validity of the new agreements in the context of the floor clauses, establishing jurisprudential doctrine on this matter about which our Supreme Court had previously ruled in its Judgments of October 16, 2017, in the sense of considering the agreed floor clause null as a consequence of the novation agreement and, subsequently, those of April 11, 2018 and September 13, 2018 in the opposite direction, declaring that the novation agreement was valid. It is a long-awaited and in…

Open availability of articles and raw research data in spanish pediatrics journals

2015

[EN]: Introduction: The open Access to publications and the raw data allows its re-use and enhances the advancement of science. The aim of this paper is to identify these practices in Spanish pediatrics journals. Method: We reviewed the author's instructions in 13 Spanish pediatrics journals, identifyingtheir open access and deposit policy. Results: Eight journals allow open access without restriction, and 5 provide information on theability to re-use and depositing data in repositories or websites. Conclusions: Most of the journals have open access, but do not promote the deposit of additionalmaterial or articles in repositories or websites.

Labor Productivity Growth: Disentangling Technology and Capital Accumulation

2014

We adopt a counterfactual approach to decompose labor productivity growth into growth of Technological Productivity (TEP), growth of the capital-labor ratio and growth of Total Factor Productivity (TFP). We bring the decomposition to the data using international countrysectoral information spanning from the 1960s to the 2000s and a nonparametric generalized kernel method, which enables us to estimate the production function allowing for heterogeneity across all relevant dimensions: countries, sectors and time. As well as documenting substantial heterogeneity across countries and sectors, we nd average TEP to account for about 44% of labor productivity growth and TEP gaps with respect to the…

TERREMOTO E RICOSTRUZIONE: MESSINA 1908, VERSO UNA PROGETTAZIONE “CONSAPEVOLE” La teoria della maggiore resistenza delle strutture “circolari” e il contributo della pubblicistica al dibattito sulla costruzione antisismica. Le storie raccontate in questo volume esaminano congiuntamente il duplice sguardo della ricerca sulla progettazione orientata in senso antisismico e sviluppata nell’ambito del dibattito nato a Messina dopo il terremoto del 1908. Se ampie si rivelano le testimonianze di forme di progettazioni “consapevoli”, cioè di accorgimenti che integrano il problema sismico all’interno di convenzioni costruttive di durata secolare, durante le fasi che hanno preceduto le molteplici rico…
