Who pays the taxes?
The European Union is legally entitled to the revenue from (1) agricultural and sugar levies, (2) customs duties, (3) a 1 percent rate on each Member States' value added tax base, and (4) a resource on the basis of GNP. Currently, the Union is actively involved in the search for a fifth own revenue source. Therefore, the European Commission (DG XIX) has invited the authors to trace 'who pays the taxes'. As requested, our report gives a general account of methods to investigate impacts of taxation. More specifically, we have estimated the incidence of national tax systems (Germany, the Netherlands, Spain and the United Kingdom), and the incidence of present own resources and prospective new (tax) resources of the European Union. Up till now, such information was not (readily) available.tax incidence in the European Union, prospective new EU tax resources

Additions to the catalogue of the Gasteromycetes from Mexico, with especial emphases on the genera Blumenavia and Tulostoma.
[EN] Blumenavia toribiotalpaensis is considered as a synonym of B. rhacodes. On the other hand, Tulostoma dumeticola, T. lloydii and T. lusitanicum are three new records for Mexico.[ES] Blumenavia toribiotalpaensis es sinónima de B. rhacodes. Por otro lado, se citan por primera vez en México Tulostoma dumeticola, T. lloydii y T. lusitanicum.Peer reviewe
The distribution of effective tax burdens in four EU countries
National policymakers are increasingly aware that their tax policy options are constrained by international tax competition. Important features of national tax systems - notably the tax mix, tax rates and rules which define the tax base - will influence decisions of firms and individuals regarding the location and (re)structuring of economic activities. The aim of the present paper is twofold: Firstly, we detail the tax mix of four member states of the European Union (Germany, The Netherlands, Spain and United Kingdom). Secondly, the paper aims to trace the distribution of the tax burden over rich and poor households in these four countries. Although tax mix and tax rates differ considerably among the four countries included in the study, the distribution of tax burdens proves to be amazingly similar.Distribution of tax burden, European Union; tax mix of Germany, the Netherlands, Spain and United Kingdom
Biomarkers in ocular chronic graft versus host disease: tear cytokine- and chemokine-based predictive model.
Producción CientíficaPurpose: To develop a tear molecule level-based predictive model based on a panel of tear cytokines and their correlation with clinical features in ocular chronic graft versus host disease (cGVHD).
Methods: Twenty-two ocular cGVHD patients and 21 healthy subjects were evaluated in a controlled environmental research laboratory (CERLab). Clinical parameters were recorded, and tears were collected. Levels of 15 molecules (epidermal growth factor [EGF], IL receptor antagonist [IL-1Ra], IL-1β, IL-2, IL-6, IL-8/CXCL8, IL-10, IL-12p70, IL-17A, interferon inducible protein [IP]-10/CXCL10, IFN-γ, VEGF, TNF-α, eotaxin 1, and regulated on activation normal T cell expressed and secreted [RANTES]) were measured by multiplex-bead assay and correlated with clinical parameters. Logistic regression was used to develop a predictive model. Leave-one-out cross-validation was applied. Classification capacity was evaluated in a cohort of individuals with dry eye (DE) of other etiologies different from GVHD.
Results: Epidermal growth factor and IP-10/CXCL10 levels were significantly decreased in ocular cGVHD, positively correlating with tear production and stability and negatively correlating with symptoms, hyperemia, and vital staining. Interleukin-1Ra, IL-8/CXCL8, and IL-10 were significantly increased in ocular cGVHD, and the first two correlated positively with symptoms, hyperemia, and ocular surface integrity while negatively correlating with tear production and stability. Predictive models were generated, and the best panel was based on IL-8/CXCL8 and IP-10/CXCL10 tear levels along with age and sex, with an area under the receiving operating curve of 0.9004, sensitivity of 86.36%, and specificity of 95.24%.
Conclusions: A predictive model based on tear levels of IL-8/CXCL8 and IP-10/CXCL10 resulted in optimal sensitivity and specificity. These results add further knowledge to the search for potential biomarkers in this devastating ocular inflammatory disease.Ministry of Economy and Competitiveness, Madrid, Spain, SAF-2010 15631 (AES)
Influence of environmental factors in the in vitro dehydration of hydrogel and silicone hydrogel contact lenses
Purpose: To analyze in vitro the influence of different
environmental conditions on the dehydration pattern of
seven currently marketed hydrogel (Hy) and silicone hydrogel
(Si-Hy) contact lenses (CL). Methods: Three Hy and four
Si-Hy CLs were evaluated. CLs were exposed to four different
relative humidity (RH) conditions (5%, 30%, 50%, and
70%) and two air flow (AF) rates (0 and 2.75 m/seg) within
an environmental chamber. Dehydration was assessed using
the gravimetric method. Data were taken at baseline, 5, 10,
15, 20, 30, 45, 60, 90, and 120 minutes of exposure. Dehydration
rate (DR), valid dehydration (VD) and stabilization
time were calculated. Results: The interaction between RH,
AF and the type of the CL material had a significant effect
(p 0.03) on DR up to 60 minutes. The maximum differences
in VD values among CL occurred around 15 minutes exposure
varying from 25.16% to 42.75%. Stabilization time was
quicker under the 5%RH with AF condition than under 70%
RH without AF one for most CLs. Conclusions: Lower RH
seems to increase CL dehydration being further accelerated
with the AF presence. The dehydration pattern is material
dependent, thus current marketed CLs behave differently
under several controlled environmental conditions. Future in
vivo studies should confirm these outcomes.The present study was partially supported by Junta Castilla y Leon (GR217 and VA145A11-2); by Junta de Castilla y Leon and European Social Fund (VA317-11); by Junta de Castilla y Leon and European Regional Development Fund (O22/12/VA/0112) and by Ministerio de Economia y Competitividad through Centro para el Desarrollo Tecnologico Industrial (IDI-2006-0676)
Psychosocial factors related to physical activity in frail and prefrail elderly people
Background: Increased physical activity (PA) is a very important factor in a healthy aging lifestyle. Psychosocial factors have also a main role in the initiation and maintenance of this behavior, but nowadays its implications for frailty elderly people are unknown, therefore, the aim of this study was to identify the psychosociological variables of behavior change that influence the practice of (PA) in frail and prefrail elderly. Methods: A total of 103 frail and pre-frail elderly people (72 females) participated in this cross-sectional study, on the framework of the EXERNET-Elder3.0 project. Age ranged from 68–94 years (mean = 80.4 ± 5.9 years). Individualized face-to-face interviews according to the constructs of the Transtheoretical Model of Change (TTM) (decisional balance (DB) and self-efficacy (SE)], social support (SS) (family and friends) and outcome expectations (OE) were administered to all participants. Results: Significant differences were found in DB, perceived benefits (PBn), SE, family-related SS and OE as a function of stages of change (SoC) (p < 0.005), but no significant were found in perceived barriers (PBrr) (p = 0.259) and friends-related SS (p = 0.068). According to the Scheffé post-hoc test, those in advanced SoC (Action-Maintenance), scored higher than those in lower SoC (Precontemplation-Contemplation and Preparation). Conclusion: The scores obtained from the study variables differed according to the SoC, supporting the external validity for the use of the TTM in frailty elderly. Further research is needed to determine the impact of PBrr and friends-related SS on this people, as well as to identify the validity of this model in the long-term in this population
Clinical and Molecular Inflammatory Response in Sjögren Syndrome–Associated Dry Eye Patients Under Desiccating Stress
Producción CientíficaTo evaluate the response of the lacrimal function unit in Sjogren syndrome (SS)-associated dry eye patients exposed to 2 simulated daily life environ-mental conditions.
Fourteen female SS dry eye patients were exposed for 2 hours to a controlled normal condition (23 C, 45% relative humidity, and air flow 0.10 m/s) and a controlled adverse condition that simulates desic- cating stress (23 C, 5% relative humidity, and air flow 0.10 m/s). The following dry eye tests were performed before and after the exposure: tear osmolarity, phenol red thread test, conjunctival hyperemia, fluorescein tear break-up time, corneal fluorescein staining, conjunctival lissamine green staining, and Schirmer test. Levels of 16 molecules were analyzed in tears by multiplex immu- nobead analysis.Junta de Castilla y León (programa de apoyo a proyectos de investigación – Ref. VA174U14
