Heat shock proteins: essential proteins for apoptosis regulation
2008
Abstract Many different external and intrinsic apoptotic stimuli induce the accumulation in the cells of a set of proteins known as stress or heat shock proteins (HSPs). HSPs are conserved proteins present in both prokaryotes and eukaryotes. These proteins play an essential role as molecular chaperones by assisting the correct folding of nascent and stress-accumulated misfolded proteins, and by preventing their aggregation. HSPs have a protective function, that is they allow the cells to survive to otherwise lethal conditions. Various mechanisms have been proposed to account for the cytoprotective functions of HSPs. Several of these proteins have demonstrated to directly interact with compo…
Art‐omics: multi‐omics meet archaeology and art conservation
2020
Summary Multi‐omics can informally be described as the combined use of high‐throughput techniques allowing the characterization of complete microbial communities by the sequencing/identification of total pools of biomolecules including DNA, proteins or metabolites. These techniques have allowed an unprecedented level of knowledge on complex microbial ecosystems, which is having key implications in land and marine ecology, industrial biotechnology or biomedicine. Multi‐omics have recently been applied to artistic or archaeological objects, with the goal of either contributing to shedding light on the original context of the pieces and/or to inform conservation approaches. In this minireview,…
Introducing a core curriculum for respiratory sleep practitioners
2015
Abstract: The background and purpose of the HERMES (Harmonising Education in Respiratory Medicine for European Specialists) initiative has been discussed at length in previous articles [1–3]. This article aims to provide more detailed and specific insight into the process and methodology of the Sleep HERMES Task Force in developing a core curriculum in respiratory sleep medicine.
Clinical implications of airway hyper-responsiveness in COPD
2006
COPD represents one of the leading causes of mortality in the general population. This study aimed at evaluating the relationship between airway hyperresponsiveness (AHR) and COPD and its relevance for clinical practice. We performed a MEDLINE search that yielded a total of 1919 articles. Eligible studies were defined as articles that addressed specific aspects of AHR in COPD, such as prevalence, pathogenesis, or prognosis. AHR appears to be present in at least one out of two individuals with COPD. The occurrence of AHR in COPD is influenced by multiple mechanisms, among which impairment of factors that oppose airway narrowing plays an important role. The main determinants of AHR are reduct…
Asthma in the elderly: a different disease?
2016
Key points Asthma in the elderly can be difficult to identify due to modifications of its clinical features and functional characteristics. Several comorbidities are associated with asthma in the elderly, and this association differs from that observed in younger patients. In clinical practice, physicians should treat comorbidities that are correlated with asthma (i.e. rhinitis or gastro-oesophageal reflux), assess comorbidities that may influence asthma outcomes (i.e. depression or cognitive impairment) and try to prevent comorbidities related to ‘drug-associated side-effects (i.e. cataracts, arrhythmias or osteoporosis). “Geriatric asthma” should be the preferred term because it implies …
Endurance training: Is it bad for you?
2016
Educational aims To illustrate the characteristics of endurance exercise training and its positive effects on health. To provide an overview on the effects of endurance training on airway cells and bronchial reactivity. To summarise the current knowledge on respiratory health problems in elite athletes. Endurance exercise training exerts many positive effects on health, including improved metabolism, reduction of cardiovascular risk, and reduced all-cause and cardiovascular mortality. Intense endurance exercise causes mild epithelial injury and inflammation in the airways, but does not appear to exert detrimental effects on respiratory health or bronchial reactivity in recreational/non-eli…
Electrifying Organic Synthesis
2018
Abstract The direct synthetic organic use of electricity is currently experiencing a renaissance. More synthetically oriented laboratories working in this area are exploiting both novel and more traditional concepts, paving the way to broader applications of this niche technology. As only electrons serve as reagents, the generation of reagent waste is efficiently avoided. Moreover, stoichiometric reagents can be regenerated and allow a transformation to be conducted in an electrocatalytic fashion. However, the application of electroorganic transformations is more than minimizing the waste footprint, it rather gives rise to inherently safe processes, reduces the number of steps of many synth…
Convolutional Matrix Factorization for Recommendation Explanation
2018
In this paper, we introduce a novel recommendation model, which harnesses a convolutional neural network to mine meaningful information from customer reviews, and integrates it with matrix factorization algorithm seamlessly. It is a valid method to improve the transparency of CF algorithms.
Rafael l. Ninyoles: Recorregut biogràfic i intel·lectual
2020
This article presents the biography and intellectual legacy of Valencian sociologist Rafael L. Ninyoles (1943- 2019). It reviews his formative itinerary, his early contributions to the field of the sociology of language, his latest contributions to the sociology of cities and cultural spaces, and his key involvement in the promoti-on and consolidation of the sociological study of Valencian society. The article includes a note on public acknowledgements to the author, plus an annex with a selective bibliography aimed at serving the interested reader and the posthumous diffusion of Ninyoles? oeuvre.
Modelling the regenerative niche: a major challenge in biomaterials research
2015
By definition, biomaterials are developed for clinical application. In the field of regenerative medicine their principal function is to play a significant, and, if possible, an instructive role in tissue healing. In the last analysis the latter involves targeting the 'regenerative niche'. The present paper will address the problem of simulating this niche in the laboratory and adopts a life science approach involving the harnessing of heterotypic cellular communication to achieve this, that is, the ability of cells of different types to mutually influence cellular functions. Thus, co-culture systems using human cells are the methodological focus and will concern four exemplary fields of re…
