Arquitectura, urbanismo y obras públicas civiles y militares en el Atlas Geográfico de España de Tomás López de 1804

This manuscript presents a novel analysis that deals about how architecture, urban planning and civil and military public works are represented in Geographic Atlas of Spain 1804 (AGE) of Tomas Lopez. For this it has been characterized different map symbols appearing on maps, which are the benchmarks for analysis and transmit accurate information on the shape and meaning of what is represented. So, more than one hundred different symbols were found. This gives an idea of the great detail and richness of the information contained in AGE. A deeper analysis shows that eighteen of them are equivalent to other previous cartographic symbols. These were from Chevalier, D’Anville teacher, who in turn was the teacher Thomas Lopez in Paris. Additionally, we found that there are several symbols with similarity to their corresponding of the Ordinances of the Royal Corps of Engineers from 1803.El objetivo que planteamos es analizar cómo Tomás López representó en su Atlas Geográfico de España (AGE) de 1804, la arquitectura, el urbanismo y las obras públicas civiles y militares, un análisis hasta el momento inédito. Para ello se han caracterizado los diferentes símbolos cartográficos que aparecen en los mapas, que constituyen los parámetros de referencia del análisis y transmiten información fidedigna de la forma y significado de lo representado. Para esas tipologías se han encontrado ciento trece símbolos diferentes, lo que da idea de la minuciosidad y riqueza de la información contenida en los mapas. Dieciocho de ellos, son equivalentes con otros tantos símbolos cartográficos de Chevalier, maestro de D’Anville, de quien Tomás López fue discípulo en París. También hay una similitud entre cuatro símbolos del AGE con sus correspondientes signos de las Ordenanzas del Real Cuerpo de Ingenieros de 1803

Usefulness of bone turnover markers as predictors of mortality risk, disease progression and skeletal-related events appearance in patients with prostate cancer with bone metastases following treatment with zoledronic acid: TUGAMO study

Owing to the limited validity of clinical data on the treatment of prostate cancer (PCa) and bone metastases, biochemical markers are a promising tool for predicting survival, disease progression and skeletal-related events (SREs) in these patients. The aim of this study was to evaluate the predictive capacity of biochemical markers of bone turnover for mortality risk, disease progression and SREs in patients with PCa and bone metastases undergoing treatment with zoledronic acid (ZA). Methods: This was an observational, prospective and multicenter study in which ninety-eight patients were included. Patients were treated with ZA (4mg every 4 weeks for 18 months). Data were collected at baseline and 3, 6, 9, 12, 15 and 18 months after the beginning of treatment. Serum levels of bone alkaline phosphtase (BALP), aminoterminal propeptide of procollagen type I (P1NP) and beta-isomer of carboxiterminal telopeptide of collagen I (b-CTX) were analysed at all points in the study. Data on disease progression, SREs development and survival were recorded. Results: Cox regression models with clinical data and bone markers showed that the levels of the three markers studied were predictive of survival time, with b-CTX being especially powerful, in which a lack of normalisation in visit 1 (3 months after the beginning of treatment) showed a 6.3-times more risk for death than in normalised patients. Levels of these markers were also predictive for SREs, although in this case BALP and P1NP proved to be better predictors. We did not find any relationship between bone markers and disease progression. Conclusion: In patients with PCa and bone metastases treated with ZA, b-CTX and P1NP can be considered suitable predictors for mortality risk, while BALP and P1NP are appropriate for SREs. The levels of these biomarkers 3 months after the beginning of treatment are especially importantThis study was supported by Novartis Oncology Spai

Effects of IL-8 up-regulation on cell survival and osteoclastogenesis in multiple myeloma

[EN]IL-8 promotes cancer cell growth, survival, angiogenesis, and metastasis in several tumors. Herein, we investigated the sources of IL-8 production in multiple myeloma (MM) and its potential roles in MM pathogenesis. We found that bone marrow cells from patients with MM secreted higher amounts of IL-8 than healthy donors. IL-8 production was detected in cultures of CD138+ plasma cells and CD138(-) cells isolated from bone marrows of MM patients, and in three of seven human myeloma cell lines (HMCLs) analyzed. Interactions between MM and stromal cells increased IL-8 secretion by stromal cells through cell-cell adhesion and soluble factors. Interestingly, 1L8 expression also increased in HMCLs, stromal cells, and osteoclasts after treatment with the antimyeloma drugs melphalan and bortezomib. In fact, the effect of bortezomib on IL-8 production was higher than that exerted by stromal-MM cell interactions. Addition of exogenous IL-8 did not affect growth of HMCLs, although it protected cells from death induced by serum starvation through a caspase-independent mechanism. Furthermore, IL-8 induced by stromal-MM cell interactions strongly contributed to osteoclast formation in vitro, because osteoclastogenesis was markedly reduced by IL-8 specific neutralizing antibodies. In conclusion, our results implicate IL-8 in myeloma bone disease and point to the potential utility of an anti IL-8 therapy to prevent unwanted effects of IL-8 up-regulation on survival, angiogenesis, and osteolysis in MM.Spanish RTICC, Spanish Association against Cancer (AECC), the INNOCAMPUS Program , Spanish ISCIII-FIS (PI12/02591) and FEDER, Regional Council from Castilla y León (Consejería de Educación) and the Network of Centers for Regenerative Medicine and Cellular Therapy from Castilla y León

Systemic and Local Hypoxia Synergize Through HIF1 to Compromise the Mitochondrial Metabolism of Alzheimer's Disease Microglia

Microglial cells are key contributors to Alzheimer’s disease (AD), constituting the first cellular line against Aß plaques. Local hypoxia and hypoperfusion, which are typically present in peripheral inflammatory foci, are also common in the AD brain. We describe here that Aß deposits are hypoxic and hypoperfused and that Aß plaque-associated microglia (AßAM) are characterized by the expression of hypoxia-inducible factor 1 (HIF1)-regulated genes. Notably, AßAM simultaneously upregulate the expression of genes involved in anaerobic glycolysis and oxidative mitochondrial metabolism, show elongated mitochondria surrounded by rough endoplasmic reticulum, and blunt the HIF1-mediated exclusion of pyruvate from the mitochondria through the pyruvate dehydrogenase kinase 1 (PDK1). Overstabilization of HIF1 –by genetic (von Hippel-Lindau deficient microglia) or systemic hypoxia (an AD risk factor)– induces PDK1 in microglia and reduces microglial clustering in AD mouse models. The human AD brain exhibits increased HIF1 activity and a hypoxic brain area shows reduced microglial clustering. The loss of the microglial barrier associates with augmented Aß neuropathology both in the chronic hypoxia AD mouse model and the human AD brain. Thus, the synergy between local and systemic AD risk factors converges with genetic susceptibility to cause microglial dysfunction.Peer reviewe

Hypoxia compromises the mitochondrial metabolism of Alzheimer’s disease microglia via HIF1

Genetic Alzheimer’s disease (AD) risk factors associate with reduced defensive amyloid β plaque-associated microglia (AβAM), but the contribution of modifiable AD risk factors to microglial dysfunction is unknown. In AD mouse models, we observe concomitant activation of the hypoxia-inducible factor 1 (HIF1) pathway and transcription of mitochondrial-related genes in AβAM, and elongation of mitochondria, a cellular response to maintain aerobic respiration under low nutrient and oxygen conditions. Overactivation of HIF1 induces microglial quiescence in cellulo, with lower mitochondrial respiration and proliferation. In vivo, overstabilization of HIF1, either genetically or by exposure to systemic hypoxia, reduces AβAM clustering and proliferation and increases Aβ neuropathology. In the human AD hippocampus, upregulation of HIF1α and HIF1 target genes correlates with reduced Aβ plaque microglial coverage and an increase of Aβ plaque-associated neuropathology. Thus, hypoxia (a modifiable AD risk factor) hijacks microglial mitochondrial metabolism and converges with genetic susceptibility to cause AD microglial dysfunction.R.M.-D. was the recipient of a Sara Borrell fellowship from Instituto de Salud Carlos III (ISCIII) (CD09/0007).

CIBERER : Spanish national network for research on rare diseases: A highly productive collaborative initiative

Altres ajuts: Instituto de Salud Carlos III (ISCIII); Ministerio de Ciencia e Innovación.CIBER (Center for Biomedical Network Research; Centro de Investigación Biomédica En Red) is a public national consortium created in 2006 under the umbrella of the Spanish National Institute of Health Carlos III (ISCIII). This innovative research structure comprises 11 different specific areas dedicated to the main public health priorities in the National Health System. CIBERER, the thematic area of CIBER focused on rare diseases (RDs) currently consists of 75 research groups belonging to universities, research centers, and hospitals of the entire country. CIBERER's mission is to be a center prioritizing and favoring collaboration and cooperation between biomedical and clinical research groups, with special emphasis on the aspects of genetic, molecular, biochemical, and cellular research of RDs. This research is the basis for providing new tools for the diagnosis and therapy of low-prevalence diseases, in line with the International Rare Diseases Research Consortium (IRDiRC) objectives, thus favoring translational research between the scientific environment of the laboratory and the clinical setting of health centers. In this article, we intend to review CIBERER's 15-year journey and summarize the main results obtained in terms of internationalization, scientific production, contributions toward the discovery of new therapies and novel genes associated to diseases, cooperation with patients' associations and many other topics related to RD research

Funding for the WEAVE facility has been provided by UKRI STFC, the University of Oxford, NOVA, NWO, Instituto de Astrofísica de Canarias (IAC), the Isaac Newton Group partners (STFC, NWO, and Spain, led by the IAC), INAF, CNRS-INSU, the Observatoire de Paris, Région Île-de-France, CONCYT through INAOE, Konkoly Observatory (CSFK), Max-Planck-Institut für Astronomie (MPIA Heidelberg), Lund University, the Leibniz Institute for Astrophysics Potsdam (AIP), the Swedish Research Council, the European Commission, and the University of Pennsylvania.WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, will see first light in late 2022. WEAVE comprises a new 2-degree field-of-view prime-focus corrector system, a nearly 1000-multiplex fibre positioner, 20 individually deployable 'mini' integral field units (IFUs), and a single large IFU. These fibre systems feed a dual-beam spectrograph covering the wavelength range 366-959 nm at R ∼ 5000, or two shorter ranges at R ∼ 20,000. After summarising the design and implementation of WEAVE and its data systems, we present the organisation, science drivers and design of a five- to seven-year programme of eight individual surveys to: (i) study our Galaxy's origins by completing Gaia's phase-space information, providing metallicities to its limiting magnitude for ∼ 3 million stars and detailed abundances for ∼ 1.5 million brighter field and open-cluster stars; (ii) survey ∼ 0.4 million Galactic-plane OBA stars, young stellar objects and nearby gas to understand the evolution of young stars and their environments; (iii) perform an extensive spectral survey of white dwarfs; (iv) survey  ∼ 400 neutral-hydrogen-selected galaxies with the IFUs; (v) study properties and kinematics of stellar populations and ionised gas in z 1 million spectra of LOFAR-selected radio sources; (viii) trace structures using intergalactic/circumgalactic gas at z > 2. Finally, we describe the WEAVE Operational Rehearsals using the WEAVE Simulator.PostprintPeer reviewe
