Roedores e insectívoros (Mammalia) del Mioceno superior de la Seu d'Urgell Cataluña, España)

Se describen en este trabajo los Insectvoros y Roedores de tres localidades de la Seu d'Urgell. Dos de ellas (Ballestar y Can Petit, pertenecientes a la formacin Ballestar) presentan una microfauna del Vallesiense inferior con Cricetulodon hatanbergeri, Muscardinus crusafonti, Myoglis meini, etc. La otra (La Bastida, en la Formacin Piedra) presenta una microfauna perteneciente al Vallesiense superior, con Progonomys cathalai como especie predominante. El análisis de esa fauna modifica el esquema estratigráfico propuesto hasta el presente para la cuenca de la Seu d'Urgell, ya que siempre se había sostenido que la Formación Piedra era anterior a la Formación Ballestar. De ambas formaciones se da una breve descripción sedimentológica.

Nuevos datos sobre la biozonación del Burdigaliense continental de la cuenca del Vallès-Penedès

En esta nota preliminar se dan a conocer dos nuevos yacimientos de microvertebrados situados en la cuenca del Valles-Penedes. La asociación de Roedores sita ambas localidades (Can Mar Vell y Can Julia) en la MN-4, equivalente al Burdigaliense superior. Dicha asociación y las caracteristicas litológicas y sedimentológicas de la unidad litoestratigráfica que la contiene, indican la existencia de reas lacustres y palustres en torno a las que lacobertera vegetal alcanzaba un notable desarrollo. Estas zonas lacustres podan pasar lateralmente a reas distales y proximales de abanicos aluviales, en las que se desarrollaba una intensa sedimentación detrítica y predominaban las condiciones subaéreas.

La unidad de limos intermedios del delta del Llobregat corresponde a un ambiente prodeltaico en el que se han identificado, por comparación al modelo actual, subambientes de prodelta proximal, medio y medio-distal. Su agua intersticial es sinsedimentaria, hallándose en la actualidad parcialmente diluida.

Chronofunctions of Heilu soil developed from Loess in Luochuan, on the chinese Loess plateau

Soil chronofunctions are an alternative for the quantification of soil-forming processes and underlie the modeling of soil genesis. To establish soil chronofunctions of a Heilu soil profile on Loess in Luochuan, selected soil properties and the 14C ages in the Holocene were studied. Linear, logarithmic, and third-order polynomial functions were selected to fit the relationships between soil properties and ages. The results indicated that third-order polynomial function fit best for the relationships between clay (< 0.002 mm), silt (0.002-0.02 mm), sand (0.02-2 mm) and soil ages, and a trend of an Ah horizon ocurrence in the profile. The logarithmic function indicated mainly variations of soil organic carbon and pH with time (soil age). The variation in CaCO3 content, Mn/Zr, Fe/Zr, K/Zr, Mg/Zr, Ca/Zr, P/Zr, and Na/Zr ratios with soil age were best described by three-order polynomial functions, in which the trend line showed migration of CaCO3 and some elements.

Deformation properties of the Barcelona-Catania-Paris (BCP) energy density functional

We explore the deformation properties of the newly postulated Barcelona-Catania-Paris (BCP) energy density functional (EDF). The results obtained for three isotope chains of Mg, Dy, and Ra are compared to the available experimental data as well as to the results of the Gogny-D1S force. Results for the fission barrier of 240Pu are also discussed.

Effects of erosion and deposition on particle size distribution of deposited farmland soils on the chinese loess plateau

Particle size distribution (PSD) in the soil profile is strongly related to erosion, deposition, and physical and chemical processes. Water cycling and plant growth are also affected by PSD. Material sedimented upstream of the dam constructions formed large areas of deposited farmland (DF) soils on the Chinese Loess Plateau (CLP), which has been the site of the most severe soil erosion in the world. Two DFs without tillage on the CLP were chosen to study the combined effect of erosion and check dams on PSD. Eighty-eight layers (each 10 cm thick) of filled deposited farmland (FDF) soils and 22 layers of silting deposited farmland (SDF) soils of each studied soil profile were collected and 932 soil samples were investigated using laser granulometry. The particle sizes were stratified in both DFs based on soil properties and erosion resistance. The obtained results of clay and silt fractions showed similar horizontal distribution, indicating parallel characteristics of erosion and deposition processes. Fine sand represented the largest fraction, suggesting the preferential detachment of this fraction. The most erodible range of particle sizes was 0.25-0.5 mm, followed by 0.2-0.25 mm in the studied soil profiles. The correlation between particle size and soil water contents tended to increase with increasing water contents in FDF. Due to the abundant shallow groundwater, the relationship between particle size and soil water content in SDF was lost. Further studies on PSD in the DF area are needed to enhance the conservation management of soil and water resources in this region.

Daytime sleepiness with and without cataplexy in Chinese-Taiwanese patients.

BACKGROUND AND PURPOSE: Investigation of Chinese-Taiwanese patients with excessive sleepiness, but no association with other sleep disorders, and with the presence or absence of cataplexy. PATIENTS AND METHODS: Thirty-five patients, successively referred between 2002 and 2004, underwent polysomnography (PSG), repeat multiple sleep latency test (MSLT), and human leukocyte antigen (HLA) typing. Three patients without cataplexy also had cerebrospinal fluid (CSF) hypocretin measurements. RESULTS: DQB1*0602 was associated with cataplexy in over 90% of Chinese-Taiwanese cases. Absence of cataplexy and <2 sleep-onset REM periods (SOREMPs) was seen in only two subjects, but presence of two SOREMPs did not dissociate DQB1*0602 positive and negative or cataplexy positive and negative subjects. As a group, narcoleptics with cataplexy had a higher number of SOREMPs, and the mean sleep latency was much shorter in narcoleptics with cataplexy than in the non-cataplectic patients, independent of the number of SOREMPs. CONCLUSIONS: Chinese-Taiwanese patients with cataplexy present with similar HLA findings as Black and Caucasian patients, but the presence of two or more SOREMPs in Chinese-Taiwanese patients is not a sufficient diagnostic tool to identify narcolepsy. When cataplexy is not present, description of PSG nd HLA findings may be a better approach than using a label with little scientific significance, allowing for better collection of patients' phenotype.

Blood pressure and LDL-cholesterol targets for prevention of recurrent strokes and cognitive decline in the hypertensive patient: design of the European Society of Hypertension-Chinese Hypertension League Stroke in Hypertension Optimal Treatment randomized trial.

BACKGROUND AND OBJECTIVES: The SBP values to be achieved by antihypertensive therapy in order to maximize reduction of cardiovascular outcomes are unknown; neither is it clear whether in patients with a previous cardiovascular event, the optimal values are lower than in the low-to-moderate risk hypertensive patients, or a more cautious blood pressure (BP) reduction should be obtained. Because of the uncertainty whether 'the lower the better' or the 'J-curve' hypothesis is correct, the European Society of Hypertension and the Chinese Hypertension League have promoted a randomized trial comparing antihypertensive treatment strategies aiming at three different SBP targets in hypertensive patients with a recent stroke or transient ischaemic attack. As the optimal level of low-density lipoprotein cholesterol (LDL-C) level is also unknown in these patients, LDL-C-lowering has been included in the design. PROTOCOL DESIGN: The European Society of Hypertension-Chinese Hypertension League Stroke in Hypertension Optimal Treatment trial is a prospective multinational, randomized trial with a 3 × 2 factorial design comparing: three different SBP targets (1, <145-135; 2, <135-125; 3, <125 mmHg); two different LDL-C targets (target A, 2.8-1.8; target B, <1.8 mmol/l). The trial is to be conducted on 7500 patients aged at least 65 years (2500 in Europe, 5000 in China) with hypertension and a stroke or transient ischaemic attack 1-6 months before randomization. Antihypertensive and statin treatments will be initiated or modified using suitable registered agents chosen by the investigators, in order to maintain patients within the randomized SBP and LDL-C windows. All patients will be followed up every 3 months for BP and every 6 months for LDL-C. Ambulatory BP will be measured yearly. OUTCOMES: Primary outcome is time to stroke (fatal and non-fatal). Important secondary outcomes are: time to first major cardiovascular event; cognitive decline (Montreal Cognitive Assessment) and dementia. All major outcomes will be adjudicated by committees blind to randomized allocation. A Data and Safety Monitoring Board has open access to data and can recommend trial interruption for safety. SAMPLE SIZE CALCULATION: It has been calculated that 925 patients would reach the primary outcome after a mean 4-year follow-up, and this should provide at least 80% power to detect a 25% stroke difference between SBP targets and a 20% difference between LDL-C targets.

El Memorial de Barcelona a Archer Milton Huntington, el fundador de la Hispanic Society of America, y a su esposa, la escultora, Anna Hyatt Huntington.

Barcelona en 1954 se anticipo a todos los homenajes, dedicando a Archer Milton Huntington (New York, 1870- Bathel, Connecticut, 1955) un monumento en reconocimiento a su excepcional figura como coleccionista e hispanófilo y también a su esposa, Anna Vaughn Hyatt Huntington (Cambridge, 1876 - California, 1973), excelente escultora que generosamente secundo los propósitos filo hispanos de su consorte. De esta manera Barcelona quería dejar constancia de su devoción y tributo a este reconocido coleccionista y filántropo americano que ayudo a vencer el llamado "Paradigma Prescott", historiador que había defendido las tesis sobre la leyenda negra española. A la vez que se reconocía que Archer M. Huntington ocupaba un lugar preeminente en la línea del hispanismo americano conjuntamente con los nombres de George Ticknor (1791 -1871), Washington Irving (1783-1859) y Henry Longfellow (1807-1882).

The Monument Erected in Barcelona in 1954 in Honor of Archer Milton Huntington, the Founder of The Hispanic Society of America, and His Wife, Anna Hyatt Huntington, the Eminent Sculptress.

It was in 1954 that Barcelona became the first city to pay tribute to Archer Milton Huntington (New York, 1870 - Bathel, Connecticut, 1955), by erecting a monument to the memory of this outstanding collector and Hispanist, and to hiswife, Anna Vaughn Hyatt Huntington (Cambridge, 1876 - California, 1973). An excellent sculptor, Anna Hyatt Huntington was also unstinting in her support of her husband¿s Hispanic interest. The monument was Barcelona's way of recognizing and paying tribute to this greatly respected American collector and philanthropist. Huntington played a major role in refuting "Prescott's Paradigm", named after the historian whose work on Spain did much to further the Black Legend.3 Moreover, Huntington occupied an important place in American Hispanic Studies, along with such other outstanding names as George Ticknor (Boston, 1791 - 1871), Washington Irving (New York, 1783 - 1859) and Henry Longfellow (1807 - 1882).
