Una nueva subespecie para Euphorbia flavicoma DC. (Euphorbiaceae)

Con motivo de los estudios biosistemáticos realizados en el marco de una tesis doctoral [J. SIMON, Estudis Biosistics en especies Euphorbia de la subsecció Galarrhaei en la mediterránea occidental, inédita, 1993] sobre las especies no nanofanerófitas y con cápsulas verrugosas de Euphorbia subsect. Galarrhaei (Boiss.) Pax, detectamos dentro del grupo de Euphorbia flavicoma DC. algunas poblaciones de difícil adscripción. El estudio de más de 700 pliegos de esta especie, así como el análisis multivariante, realizado sobre un total de 88 caracteres, nos obliga a proponer una nueva subespecie definida ante todo por el tipo de indumento de tallos y hojas, formado por tricomas largos y patentes -muy diferentes de los cortos y crespos que se presentan en el resto de las subespecies-, y que además recubre ambas caras foliares -en el resto de las subespecies los tricomas tan solo se encuentran en el margen foliar-. Como caracteres complementarios, se pueden destacar la disposición claramente refleja de las hojas y su aspecto ligeramente seríceo.

Las comunidades liquenicas saxicolas ombrofobas de la costa del SE de EspaÑa comprendidas entre el Penyal d'Ifac (Alicante) y Almeria

The ombrophobic saxicolous lichen communities in the coastal SE Spain, between the Penyal d'Ifac (Alicante) and Almeria. The authors describe the calcicolous and silicicolous communities, as observed by them in the coast of SE Spain. They include the whole in a new alliance, Roccellion phycopsis, with two associations characterized by a number of thermophilous Trentepholia -containing species, belonging to order Arthoniales, and neighbouring from taxonomic and ecologic viewpoints. All the studied communities are aerohygrophilous, heliophobic and fairly to scarcely photophilous.

Los nummulítidos (Nummulites y Assilina) del Paleoceno Superior-Eoceno Inferior de la cuenca pirenaica: Sistemaáica.

Se ha realizado el estudio sistemático de los nummulítidos pertenecientes a los géneros Nummulites y Assilina del intervalo Paleoceno Superior - Eoceno Inferior de la Cuenca Pirenaica, a partir de muestras procedentes principalmente del sector meridional de la cuenca. Los taxones descritos se han comparado con especímenes procedentes de otras cuencas de la Mesogea: Alpes suizos (Schlieren- y Gumigelflysch) y austríacos (unidades alóctonas helvéticas), norte de Italia (Verona y Vicenza), plataformas marinas adriáticas (Eslovenia y Croacia), península de Crimea (Ucrania), Cuenca de Haymana (Anatolia central, Turquía), y Salt Range (Pakistán). Se han descrito 98 taxones de nummuiítidos -entre especies y subespecies-, de los cuales: - 66 taxones del género Nummulites, pertenecientes a los grupos de N. perforatus, N. partschi, N. rotularius, N. minewensis, N. globulus, N. laevigatus, N. distans, N. heberti y N. spirectypus. - 32 taxones del género Assilina, pertenecientes a los gmpos de A. spira, A. exponens, A. subgranulosa, A. ammonea, A. canalijera y A. alpina. En este trabajo -y siguiendo las consideraciones de Loeblich y Tappan (1987)- Assilina integra las denominaciones gen6ricas tradicionales de Assilina y Operculina.

Caracterización sísmica de una cuenca sedimentaria: análisis inicial

Mediante técnicas numéricas analizamos el efecto de una cuenca sedimentaria sobre las ondas sísmicas que la atraviesan, en el presente estudio ondas P. La cuenca sedimentaria la caracterizamos por una serie estratigráfica con un número de capas y espesor total prefijados, así como el valor medio de sus propiedades elásticas. Para cada capa individual, estos valores medios se hacen fluctuar aleatoriamente en más y en menos alrededor de sus valores medios, con un valor máximo permitido de la variación también prefijado. Los ejemplos numéricos realizados nos muestran que los parámetros que más afectan una onda que se propaga a través de una cuenca son la distancia característica o espesor de las capas individuales y la magnitud de las fluctuaciones. manifestándose la resuuesta de la serie estratigráfica como un filtro paso baja y en la aparición de resonancias. Estos efectos pueden ser observados y cuantificados a partir de un análisis de la atenuación del medio y de la dispersión de la velocidad intrínseca de las ondas P y S.

Epibiotic bryozoans on deep-water seleractinian corals from the Catalonia slope (western Mediterranean, Spain, France)

The bryozoan fauna growing on deep-water corals (Lophelia, Madrepora) from the upper-slope of Catalonia (Blanes and Banyuls-sur-mer: NW Mediterranean Sea) was studied. Among the 36 species recorded, a new species, Escharella acuta sp. nov., and a new subspecies, Escharina dutertrei protecta ssp. nov., are described; five other species have been rarely reported or were unknown from the Mediterranean Sea (Copidozoum exiguum, Amphiblestrum flemingii, Schizomavella neptuni, Smittina crystallina, Phylactellipora eximia) . This epibiotic bryozoan fauna differs clearly from shallow-water assemblages and comprises a greater proportion of boreo-atlantic species.

Precisiones cronoestratigráficas sobre la Fm. Escucha en el sector noroeste de la cuenca del Maestrazgo. Cordillera Ibérica oriental

Uno de los problemas clásicos en el estudio del registro sedimentario cretácico de la Cordillera Ibérica es la datación cronoestratigráfica de los materiales detriticos que subyacen al cretácico superior calcáreo, debido a su carácter continental y de transición. En el presente trabajo se muestrean dos series de la Fm. Escucha situadas en los depocentros de las cubetas de Calanda y de Castellote, para realizar un análisis palinológico de las mismas y compararlo con otros análisis realizados en la cubeta de Traiguera, en donde la edad está contrastada con el contenido en ammonites. Los resultados de este análisis, muestran un contenido en microflora equivalente para las dos series, asi como con las de Benassal, Benifassa, Traiguera y Salom. Este hecho nos lleva a datar a la Fm. Escucha en este sector como Albiense inferior terminal- Albiense medio, con 10 cual se contribuye a aclarar las relaciones estratigráficas entre las formaciones de Escucha, Val de la Piedra y Calizas de Benassal.

FDI from European Union to Western Balkan Countires: is the economic development being intensified in the region?

La inversió estrangera directa és important a causa dels seus avantatges per al país d'acollida, per exemple augmentarà la competitivitat i s’intensifica el desenvolupament. Els avantatges són significatives als països dels Balcans occidentals que s'enfronten a les dificultats de la competència i el creixement més baix de la UE-27. El treball analitza el tipus dominant de la IED de la UE-27 a la regió dels Balcans Occidentals a escala nacional i sectorial per formar les implicacions sobre el futur creixement de la competitivitat i la intensitat del desenvolupament econòmic. Es troba que la IED horitzontal domina als Balcans occidentals, per tant, el creixement de la competitivitat i el desenvolupament econòmic es va intensificar a la regió.

If you want me to stay, pay

Devolution of political power is constantly on the political agenda in both Italy and Spain. Fiscal policy in these countries has granted specific privileges to some regions. Valle d’Aosta/Vallée d’Aoste,(VdA) and País Vasco-Euskadi (PV) have an extensive say over spending decisions, and receive nearly all regional tax revenues. Although both VdA and PV are among the richest regions in each country, both are net beneficiaries of the fiscal equalisation system. This preferential treatment is the outcome of a fiscal system with limits on taxing power and debt issuance, and is meant as a compensation for the lack of autonomy. It so prevents calls for more fiscal autonomy, or even outright secession. The economic effects of this asymmetric federalism are negative Although partial equalisation reduces excessive redistribution built in the fiscal equalisation system, more autonomy could pay off with more efficient government. Asymmetric federalism moreover creates a political impasse in the negotiation of a more efficient tax system and financing arrangement.

Gazpacho consumption is associated with lower blood pressure and reduced hypertension in a high cardiovascular risk cohort. Cross-sectional study of the PREDIMED trial

Hypertension is a major public health problem and a leading cause of death and disability in both developed and developing countries, affecting onequarter of the world"s adult population. Our aim was to evaluate whether the consumption of gazpacho, a Mediterranean vegetable-based cold soup rich in phytochemicals, is associated with lower blood pressure (BP) and/or reduced prevalence of hypertension in individuals at high cardiovascular risk. Methods and results: We selected 3995 individuals (58% women, mean age 67 y) at high cardiovascular risk (81% hypertensive) recruited into the PREDIMED study. BP, weight, and dietary and physical activity data were collected. In multivariate linear regression analyses, after adjustment, moderate and high gazpacho consumption categories were associated with reduced mean systolic BP of 1.9 mm Hg [95% confidence interval (CI): 3.4; 0.6] and 2.6 mm Hg (CI: 4.2; 1.0), respectively, and reduced diastolic BP of 1.5 mm Hg (CI: 2.3; 0.6) and 1.9 mm Hg (CI: 2.8; 1.1). By multiple-adjusted logistic regression analysis, gazpacho consumption was associated with a lower prevalence of hypertension, with OR Z 0.85 (CI: 0.73; 0.99) for each 250 g/week increase and OR Z 0.73 (CI: 0.55; 0.98) for high gazpacho consumption groups compared to the no-consumption group. Conclusions: Gazpacho consumption was inversely associated with systolic and diastolic BP and prevalence of hypertension in a cross-sectional Mediterranean population at high cardiovascular risk. The association between gazpacho intake and reduction of BP is probably due to synergy among several bioactive compounds present in the vegetable ingredients used to make the recipe.

A short screener is valid for assessing mediterranean diet adherence among older spanish men and women

Ensuring the accuracy of dietary assessment instruments is paramount for interpreting diet-disease relationships. The present study assessed the relative and construct validity of the 14-point Mediterranean Diet Adherence Screener (MEDAS) used in the Prevencio´n con Dieta Mediterra´nea (PREDIMED) study, a primary prevention nutrition-intervention trial. A validated FFQ and the MEDAS were administered to 7146 participants of the PREDIMED study. The MEDASderived PREDIMED score correlated significantly with the corresponding FFQ PREDIMED score (r = 0.52; intraclass correlation coefficient = 0.51) and in the anticipated directions with the dietary intakes reported on the FFQ. Using Bland Altman"s analysis, the average MEDAS Mediterranean diet score estimate was 105% of the FFQ PREDIMED score estimate. Limits of agreement ranged between 57 and 153%. Multiple linear regression analyses revealed that a higher PREDIMED score related directly (P , 0.001) to HDL-cholesterol (HDL-C) and inversely (P , 0.038) to BMI, waist circumference, TG, the TG:HDL-C ratio, fasting glucose, and the cholesterol:HDL-C ratio. The 10-y estimated coronary artery disease risk decreased as the PREDIMED score increased (P , 0.001). The MEDAS is a valid instrument for rapid estimation of adherence to the Mediterranean diet and may be useful in clinical practice.

A 14-item Mediterranean diet assessment tool and obesity indexes among high-risk subjects: the PREDIMED trial

Objective: Independently of total caloric intake, a better quality of the diet (for example, conformity to the Mediterranean diet) is associated with lower obesity risk. It is unclear whether a brief dietary assessment tool, instead of full-length comprehensive methods, can also capture this association. In addition to reduced costs, a brief tool has the interesting advantage of allowing immediate feedback to participants in interventional studies. Another relevant question is which individual items of such a brief tool are responsible for this association. We examined these associations using a 14-item tool of adherence to the Mediterranean diet as exposure and body mass index, waist circumference and waist-to-height ratio (WHtR) as outcomes. Design: Cross-sectional assessment of all participants in the"PREvención con DIeta MEDiterránea" (PREDIMED) trial. Subjects: 7,447 participants (55-80 years, 57% women) free of cardiovascular disease, but with either type 2 diabetes or $3 cardiovascular risk factors. Trained dietitians used both a validated 14-item questionnaire and a full-length validated 137-item food frequency questionnaire to assess dietary habits. Trained nurses measured weight, height and waist circumference. Results: Strong inverse linear associations between the 14-item tool and all adiposity indexes were found. For a two-point increment in the 14-item score, the multivariable-adjusted differences in WHtR were 20.0066 (95% confidence interval,- 0.0088 to 20.0049) for women and-0.0059 (-0.0079 to-0.0038) for men. The multivariable-adjusted odds ratio for a WHtR.0.6 in participants scoring $10 points versus #7 points was 0.68 (0.57 to 0.80) for women and 0.66 (0.54 to 0.80) for men. High consumption of nuts and low consumption of sweetened/carbonated beverages presented the strongest inverse associations with abdominal obesity. Conclusions: A brief 14-item tool was able to capture a strong monotonic inverse association between adherence to a good quality dietary pattern (Mediterranean diet) and obesity indexes in a population of adults at high cardiovascular risk.

Low-fat dairy products and blood pressure: follow-up of 2290 older persons at high cardiovascular risk participating in the PREDIMED study

High blood pressure (BP) has been ranked as the most important risk factor worldwide regarding attributable deaths. Dietary habits are major determinants of BP. Among them, frequent intake of low-fat dairy products may protect against hypertension. Our aim was to assess the relationship between low-fat dairy product intake and BP levels and their changes after 12 month follow-up in a cohort of asymptomatic older persons at high cardiovascular risk recruited into a large-scale trial assessing the effects of Mediterranean diets on cardiovascular outcomes. Data from 2290 participants, including 1845 with hypertension, were available for analyses. Dairy products were not a specific part of the intervention; thus, data were analysed as an observational cohort. Dietary information was collected with validated semi-quantitative FFQ and trained personnel measured BP. To assess BP changes, we undertook cross-sectional analyses at baseline and at the end of follow-up and longitudinal analyses. A statistically significant inverse association between low-fat dairy product intake and systolic BP was observed for the 12-month longitudinal analysis. In the longitudinal analysis, the adjusted systolic and diastolic BP were significantly lower in the highest quintile of low-fat dairy product intake ( 2 4·2 (95% CI 2 6·9, 2 1·4) and 2 1·8 (95% CI 2 3·2, 2 0·4) mmHg respectively), whereas the point estimates for the difference in diastolic BP indicated a modest non-significant inverse association. Intake of low-fat dairy products was inversely associated with BP in an older population at high cardiovascular risk, suggesting a possible protective effect against hypertension.

The mediterranean diet pattern and its main components are associated with lower plasma concentrations of tumor necrosis factor receptor 60 in patients at high risk for cardiovascular disease

Adherence to aMediterranean diet (MD) is associated with a reduced risk of coronary heart disease. However, themolecular mechanisms involved are not fully understood. The aim of this studywas to compare the effects of 2MD with those of a lowfat- diet (LFD) on circulating inflammatory biomarkers related to atherogenesis. A total of 516 participants included in the PreventionwithMediterraneanDiet Studywere randomized into 3 intervention groups [MD supplementedwith virgin olive oil (MD-VOO); MD supplemented with mixed nuts (MD-Nuts); and LFD]. At baseline and after 1 y, participants completed FFQ and adherence to MD questionnaires, and plasma concentrations of inflammatory markers including intercellular adhesion molecule-1(ICAM-1), IL-6, and 2 TNF receptors (TNFR60 and TNFR80) were measured by ELISA. At 1 y, the MD groups had lower plasma concentrations of IL-6, TNFR60, and TNFR80 (P , 0.05), whereas ICAM-1, TNFR60, and TNFR80 concentrations increased in the LFD group (P , 0.002). Due to between-group differences, participants in the 2 MD groups had lower plasma concentrations of ICAM-1, IL-6, TNFR60, and TNFR80 compared to those in the LFD group (P # 0.028). When participants were categorized in tertiles of 1-y changes in the consumption of selected foods, those in the highest tertile of virgin olive oil (VOO) and vegetable consumption had a lower plasma TNFR60 concentration compared with those in tertile 1 (P,0.02).Moreover, the only changes in consumption thatwere associated with 1-y changes in the geometricmean TNFR60 concentrations were those of VOO and vegetables (P = 0.01). This study suggests that a MD reduces TNFR concentrations in patients at high cardiovascular risk.

Polymorphisms cyclooxygenase-2 -765G>C and interleukin-6 -174G>C are associated with serum inflammation markers in a high cardiovascular risk population and do not modify the response to a Mediterranean diet supplemented with virgin olive oil or nuts

Inflammation is involved in cardiovascular diseases. Some studies have found that the Mediterranean diet (MD) can reduce serum concentrations of inflammation markers. However, none of these studies have analyzed the influence of genetic variability in such a response. Our objective was to study the effect of the -765G.C polymorphism in the cyclooxygenase-2 (COX-2) gene and the -174G.C polymorphism in the interleukin-6 (IL-6) gene on serum concentrations of IL-6, C-reactive protein, intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule-1 as well as their influence on the response toa nutritional interventionwithMD.An intervention study ina high cardiovascular riskMediterranean population (314 men and 407 women) was undertaken. Participants were randomly assigned to consume a low-fat control diet or a MD supplementedwith virgin olive oil ornuts.Measureswereobtained at baseline and after a 3-mointervention period.At baseline, the COX-2 -765G.C polymorphismwas associated with lower serum IL-6 (5.85 6 4.82 in GG vs. 4.74 6 4.14 ng/L in C-allele carriers; P ¼ 0.002) and ICAM-1 (265.8 6 114.8 in GG vs. 243.0 6 107.1 mg/L in C-carriers; P ¼ 0.018) concentrations. These differences remained significant aftermultivariate adjustment. The IL-6 -174G.C polymorphism was associatedwith higher (CC vs. G-carriers) serumICAM-1concentrations in bothmenandwomenandwithhigherserumIL-6 concentrations inmen.Following the dietary intervention, no significant gene x diet interactions were found. In conclusion, although COX-2 -765G.C and IL-6 -174G.C polymorphismswere associatedwith inflammation, consuming aMD(either supplemented with virgin olive oil or nuts) reduced the concentration of inflammation markers regardless of these polymorphisms.
