LA ARMONIZACIÓN CONTABLE EN LAS CC.LL. EUROPEAS: LA INFLUENCIA DEL ENTORNO
The main purpose of this paper is to identify the pattern of convergence of theeconomic environments that characterise the European Local Governments. In thisregard, our findings suggest that the key factors of the environment have not tended toconverge across Europe. The convergence has taken place at the regional level, amonggeographically close and economically similar countries. Given the importance of theenvironment in the process of accounting harmonisation, this fact may hinder the shorttermadoption of a single common accounting system for all European countries. En este artículo analizamos el patrón de convergencia del entorno en el que operan las CC.LL. europeas. Nuestros resultados ponen de manifiesto que los factores clave del entorno no han tendido a converger a escala europea, sino más bien a escala regional, entre países geográficamente próximos y económicamente afines. Considerando la importancia del entorno en el proceso de armonización contable, este hecho supone un obstáculo para el diseño a corto plazo de un sistema contable común para las CC.LL. europeas.Contabilidad pública, armonización contable, convergencia del entorno, dinámica de las distribuciones.

Aquaporin-11 Contributes to TGF-β1-Induced Endoplasmic Reticulum Stress in Human Visceral Adipocytes: Role in Obesity-Associated Inflammation
Aquaporin-11 (AQP11) is expressed in human adipocytes, but its functional role remains unknown. Since AQP11 is an endoplasmic reticulum (ER)-resident protein that transports water, glycerol, and hydrogen peroxide (H2O2), we hypothesized that this superaquaporin is involved in ER stress induced by lipotoxicity and inflammation in human obesity. AQP11 expression was assessed in 67 paired visceral and subcutaneous adipose tissue samples obtained from patients with morbid obesity and normal-weight individuals. We found that obesity and obesity-associated type 2 diabetes increased (p < 0.05) AQP11 mRNA and protein in visceral adipose tissue, but not subcutaneous fat. Accordingly, AQP11 mRNA was upregulated (p < 0.05) during adipocyte differentiation and lipolysis, two biological processes altered in the obese state. Subcellular fractionation and confocal microscopy studies confirmed its presence in the ER plasma membrane of visceral adipocytes. Proinflammatory factors TNF-α, and particularly TGF-β1, downregulated (p < 0.05) AQP11 mRNA and protein expression and reinforced its subcellular distribution surrounding lipid droplets. Importantly, the AQP11 gene knockdown increased (p < 0.05) basal and TGF-β1-induced expression of the ER markers ATF4 and CHOP. Together, the downregulation of AQP11 aggravates TGF-β1-induced ER stress in visceral adipocytes. Owing to its “peroxiporin” properties, AQP11 overexpression in visceral fat might constitute a compensatory mechanism to alleviate ER stress in obesity

Clinical and Pathological Characterization of Lynch-Like Syndrome
Background & aims: Lynch syndrome is characterized by DNA mismatch repair (MMR) deficiency. Some patients with suspected Lynch syndrome have DNA MMR deficiencies but no detectable mutations in genes that encode MMR proteins-this is called Lynch-like syndrome (LLS). There is no consensus on management of patients with LLS. We collected data from a large series of patients with LLS to identify clinical and pathology features.
Methods: We collected data from a nationwide-registry of patients with colorectal cancer (CRC) in Spain. We identified patients whose colorectal tumors had loss of MSH2, MSH6, PMS2, or MLH1 (based on immunohistochemistry), without the mutation encoding V600E in BRAF (detected by real-time PCR), and/or no methylation at MLH1 (determined by methylation-specific multiplex ligation-dependent probe amplification), and no pathogenic mutations in MMR genes, BRAF, or EPCAM (determined by DNA sequencing). These patients were considered to have LLS. We collected data on demographic, clinical, and pathology features and family history of neoplasms. The χ2 test was used to analyze the association between qualitative variables, followed by the Fisher exact test and the Student t test or the Mann-Whitney test for quantitative variables.
Results: We identified 160 patients with LLS; their mean age at diagnosis of CRC was 55 years and 66 patients were female (41%). The Amsterdam I and II criteria for Lynch syndrome were fulfilled by 11% of cases and the revised Bethesda guideline criteria by 65% of cases. Of the patients with LLS, 24% were identified in universal screening. There were no proportional differences in sex, indication for colonoscopy, immunohistochemistry, pathology findings, or personal history of CRC or other Lynch syndrome-related tumors between patients who met the Amsterdam and/or Bethesda criteria for Lynch syndrome and patients identified in universal screening for Lynch syndrome, without a family history of CRC.
Conclusions: Patients with LLS have homogeneous clinical, demographic, and pathology characteristics, regardless of family history of CRC

Spain was one of the European countries with the highest incidence during the first wave. As a part of a consortium to monitor and study the evolution of the epidemic, we sequenced 2,170 samples, diagnosed mostly before lockdown measures. Here, we identified at least 500 introductions from multiple international sources and documented the early rise of two dominant Spanish epidemic clades (SECs), probably amplified by superspreading events. Both SECs were related closely to the initial Asian variants of SARS-CoV-2 and spread widely across Spain. We inferred a substantial reduction in the effective reproductive number of both SECs due to public-health interventions (Re < 1), also reflected in the replacement of SECs by a new variant over the summer of 2020. In summary, we reveal a notable difference in the initial genetic makeup of SARS-CoV-2 in Spain compared with other European countries and show evidence to support the effectiveness of lockdown measures in controlling virus spread, even for the most successful genetic variants.This work was mainly funded by the Instituto de Salud Carlos III project COV20/00140, with additional funding by Spanish National Research Council project CSIC-COV19-021, Ministerio de Ciencia project PID2019-104477RB-100, ERC StG 638553 and ERC CoG 101001038 to I.C., and BFU2017-89594R to F.G.C.

A Further Step into the ELGH and TLGH for Spain and Italy
Nowadays many developing countries focus on economic policies for promoting international tourism and exports expansion as a potential source of economic growth of the country. However, the understanding of the relationship between exports and economic growth is still ongoing. When treating the relationship between tourism and economic growth, considering tourism as a non-traditional export few studies have been published to date. This paper has the objective to assess if exports and tourism have really promoted growth by means of the export-led growth hypothesis (ELGH) and the tourism-led growth hypothesis (TLGH). The cases under analysis are Spain and Italy, two of the most important countries worldwide regarding the expansion of tourism. Cointegration techniques and the multivariate Granger causality test are applied. Results reveal that exports cause economic growth in the long-term for both countries, whilst only for Spain tourism appears as a factor which influences economic growth in the lon-run

Reelin in Alzheimer's Disease, Increased Levels but Impaired Signaling: When More is Less
In the continuing search for proteins that play a role in Alzheimer's disease (AD) and that are related to the pathological hallmarks, those that influence cognitive function and that constitute potential therapeutic targets deserve special interest. Reelin is a signaling protein that is involved in a cascade of cytoplasmic events that control tau phosphorylation and that regulate synaptic neurotransmission, plasticity, and memory. Both Reelin expression and glycosylation are modulated by amyloid-β (Aβ), suggesting that the activity of Reelin could be affected in AD and hence, its possible influence on this pathology should be taken into consideration. The levels of Reelin in the brain of AD patients appear to be altered and interestingly, disrupted Reelin signaling is associated with increased tau phosphorylation as well as with amyloid-β protein precursor processing. We discuss here the somewhat contradictory data regarding Reelin levels in AD and we evaluate the processing of the Reelin receptor, ApoER2, and other downstream events, such as the phosphorylation of the intracellular adapter Dab1. Together with brain Reelin levels, these changes may represent a relevant read-out of Reelin signaling in the human brain.Peer reviewe
The apolipoprotein receptor LRP3 compromises APP levels
Background: members of the low-density lipoprotein (LDL) receptor family are involved in endocytosis and in transducing signals, but also in amyloid precursor protein (APP) processing and β-amyloid secretion. ApoER2/LRP8 is a member of this family with key roles in synaptic plasticity in the adult brain. ApoER2 is cleaved after the binding of its ligand, the reelin protein, generating an intracellular domain (ApoER2-ICD) that modulates reelin gene transcription itself. We have analyzed whether ApoER2-ICD is able to regulate the expression of other LDL receptors, and we focused on LRP3, the most unknown member of this family. We analyzed LRP3 expression in middle-aged individuals (MA) and in cases with Alzheimer's disease (AD)-related pathology, and the relation of LRP3 with APP. Methods: the effects of full-length ApoER2 and ApoER2-ICD overexpression on protein levels, in the presence of recombinant reelin or Aβ42 peptide, were evaluated by microarray, qRT-PCRs, and western blots in SH-SY5Y cells. LRP3 expression was analyzed in human frontal cortex extracts from MA subjects (mean age 51.8±4.8 years) and AD-related pathology subjects [Braak neurofibrillary tangle stages I-II, 68.4±8.8 years; III-IV, 80.4 ± 8.8 years; V-VI, 76.5±9.7 years] by qRT-PCRs and western blot; LRP3 interaction with other proteins was assessed by immunoprecipitation. In CHO cells overexpressing LRP3, protein levels of full-length APP and fragments were evaluated by western blots. Chloroquine was employed to block the lysosomal/autophagy function. Results: we have identified that ApoER2 overexpression increases LRP3 expression, also after reelin stimulation of ApoER2 signaling. The same occurred following ApoER2-ICD overexpression. In extracts from subjects with AD-related pathology, the levels of LRP3 mRNA and protein were lower than those in MA subjects. Interestingly, LRP3 transfection in CHO-PS70 cells induced a decrease of full-length APP levels and APP-CTF, particularly in the membrane fraction. In cell supernatants, levels of APP fragments from the amyloidogenic (sAPPα) or non-amyloidogenic (sAPPβ) pathways, as well as Aβ peptides, were drastically reduced with respect to mock-transfected cells. The inhibitor of lysosomal/autophagy function, chloroquine, significantly increased full-length APP, APP-CTF, and sAPPα levels. Conclusions: ApoER2/reelin signaling regulates LRP3 expression, whose levels are affected in AD; LRP3 is involved in the regulation of APP levels
Decreased generation of C-terminal fragments of apoer2 and increased reelin expression in Alzheimer’s disease
Increasing evidence indicates that altered reelin signaling could contribute to synaptic dysfunction in Alzheimer's disease (AD). We found that reelin protein and mRNA levels were increased in the AD brain (particularly at advanced Braak stages in apolipoprotein E4 noncarriers), compared with that of control subjects. The β-amyloid (Aβ) protein impairs reelin activity and increases reelin expression through a mechanism that is not yet understood. To explore that mechanism, we examined the effect of Aβ aa 1–42 (Aβ42) on DNA methylation of the RELN promoter and the processing of reelin receptor apolipoprotein E receptor 2 (ApoER2) in differentiated SH-SY5Y cells because ApoER2 C-terminal fragments (CTFs), generated after reelin binding, regulate reelin expression. We found that Aβ42 decreased nuclear levels of DNA-methyltransferase 1. However, RELN promoter methylation did not change in Aβ42- treated cells or in AD brain extracts. Instead, the levels of ApoER2-CTF appeared significantly lower in Aβ42-treated cells and in AD extracts from advanced Braak stages of apolipoprotein E4 noncarriers. Our data show that ApoER2- CTF levels are decreased, whereas reelin expression is increased in AD brain at advanced Braak stages and after Aβ treatment, supporting the view that ApoER2-CTF exerts a modulatory role on reelin expression.—Mata-Balaguer, T., Cuchillo-Ibañez, I., Calero, M., Ferrer, I., Sáez-Valero, J.
