En numerosas novelas, Vargas Llosa aborda los mismo temas que en sus ensayos de manera que se establecen ecos entre ficción y no ficción, ecos que, de una u otra manera, apoyan implícitamente la verdad de los textos literarios por la de los ensayos historiográficos. También el hecho de que el narrador en sus novelas a menudo tenga rasgos autobiográficos evidentes de su autor contribuye a borrar las fronteras entre universo de ficción interno y universo externo. Además, en varias novelas Vargas Llosa tiende a borrar las fronteras entre los géneros, y acerca la novela al ensayo Al comparar El hablador, novela que publicó en 1987, con el ensayo José María Arguedas o las ficciones del indigenismo, de 1996, nos interrogamos acerca de la relación que existe entre las ideas sobre el indigenismo expresadas por Vargas Llosa en la ficción y fuera de ella.

Poor therapeutic adherence is a major issue faced by physicians today. This paper summarizes the adherence rates with oral bisphosphonate (OBP) treatment in clinical practice and their impact on clinical outcomes. Studies systematically demonstrated that overall compliance and persistence with OBPs among osteoporotic women are poor. Although extending dosing intervals improved adherence, the gains are suboptimal. Most importantly, low compliance and persistence rates consistently resulted in increased rates of fractures. The results emphasize the importance of adherence to treatment to achieve optimal antifracture efficacy. There is an urgent need to implement strategies and to encourage physicians to take measures that increase patients' awareness of the need to use osteoporosis medications as directed in order to benefit from them fully.

Vaccinia H1-related (VHR) protein tyrosine phosphatase dephosphorylates and thereby inactivates extracellular signal-regulated kinases Erk1/2 and c-Jun N-terminal kinases Jnk1/2. These mitogen-activated protein (MAP) kinases mediate major signaling pathways triggered by extracellular growth factor, stress, or cytokines and regulate cellular processes such as differentiation, proliferation and apoptosis. Unlike many MAP kinase phosphatases (MKPs), VHR expression is not induced in response to activation of MAP kinases, but is instead regulated during cell cycle progression. The loss of VHR causes cell cycle arrest in HeLa carcinoma cells, suggesting that VHR inhibition may be a useful approach to halt the growth of cancer cells without detrimental effects on normal cells. Here we report the development of multidentate small-molecule inhibitors of VHR that inhibit its enzymatic activity at nanomolar concentrations and are selective for VHR over HePTP and MKP-1. This novel small molecular probe, ML113 (CID-6161281) appears to interact with both the phosphate-binding pocket and several distinct hydrophobic regions within VHR's active site. As a result, it will serve as a useful tool in probing these interactions and elucidating the molecular mechanism underlying the selectivity against this phosphatase, in addition to providing greater understanding of the functional consequences for cancer biology.

Vernalization is known to promote flowering in Arabidopsis thaliana by inhibiting the expression of a strong repressor: FLOWERING LOCUS C (FLC). The recent cloning of an FLC-LIKE gene in sugar beet (Beta vulgaris; BvFL1) and – here – in root chicory (Cichorium intybus; CiFL1) suggests the conservation of FLC biological function during evolution of eudicots. Hence physiological questions that remain difficult to address in Arabidopsis can be studied in other species. We investigated the correlation between CiFL1 expression and plant-age dependent responsiveness to vernalization. We also studied the effect of post-vernalization growing temperature, which can stabilize or erase the vernalized state. [less ▲]

Long-term care (LTC hereafter) concerns people who depend on help to carry out daily activities. It is mainly delivered informally by families and to a lesser extent formally by professional care assistants and nursing homes. Most EU governments are also involved in some way in the provision or financing of LTC services. Right now, the future of LTC provision appears to be gloomy, for demographic, societal and financial reasons. This TSE Note studies the strengths and weaknesses of three institutions providing LTC services - namely the family, the State and the private insurance market - and provides policy recommendations based on the view that governments should take the leadership towards a comprehensive approach of the dependency problem, while relying as much as possible on the family and the market.

In birds, corticosteroid-binding globulin (CBG) binds corticosterone, progesterone and testosterone. The concentration of each ligand can alter the binding of the other ligands through competitive interactions. Thus, an increase in corticosterone or progesterone may displace testosterone bound to CBG, leading to an increase in bioactive free testosterone levels without affecting total testosterone levels in the circulation. Aggressive interactions increase plasma total testosterone levels in some birds but not in others. Here, we tested the hypothesis that aggressive encounters in the late breeding season would not increase total testosterone levels in plasma, but would alter CBG, total corticosterone or total progesterone levels in such a way as to modify the number of available binding sites and therefore occupancy by testosterone. A marked decrease in CBG occupancy by testosterone would indirectly suggest an increase in free testosterone levels in plasma. Wild male white-crowned sparrows were exposed to a simulated territorial intrusion (STI) or control for 30 min. Subjects were then caught and bled. We measured CBG using a ligand-binding assay and corticosterone, progesterone and testosterone using highly sensitive radioimmunoassays. STI significantly increased aggressive behaviors but did not affect plasma total testosterone levels. STI significantly increased plasma CBG and total corticosterone levels and decreased plasma total progesterone levels. We predict that CBG occupancy by corticosterone will increase slightly following an aggressive encounter. However, this small change is unlikely to increase free testosterone levels, because of the large number of seemingly unoccupied CBG binding sites in these subjects. [less ▲]

Mitochondrial F1FO-ATP synthase of chlorophycean algae is a stable dimeric complex of 1,600 kDa. It lacks the classic subunits that constitute the peripheral stator-stalk and the orthodox polypeptides involved in the dimerization of the complex. Instead, it contains nine polypeptides of unknown evolutionary origin named ASA1 to ASA9. The isolated enzyme exhibited a very low ATPase activity (0.03 Units/mg), that increased upon heat treatment, due to the release of the F-1 sector. Oligomycin was found to stabilize the dimeric structure of the enzyme, providing partial resistance to heat dissociation. Incubation in the presence of low concentrations of several non-ionic detergents increased the oligomycin-sensitive ATPase activity up to 7.0-9.0 Units/mg. Incubation with 3% (w/v) taurodeoxycholate monomerized the enzyme. The monomeric form of the enzyme exhibited diminished activity in the presence of detergents and diminished oligomycin sensitivity. Cross-linking experiments carried out with the dimeric and monomeric forms of the ATP synthase suggested the participation of the ASA6 subunit in the dimerization of the enzyme. The dimeric enzyme was more resistant to heat treatment, high hydrostatic pressures, and protease digestion than the monomeric enzyme, which was readily disrupted by these treatments. We conclude that the fully-active algal mitochondrial ATP synthase is a stable catalytically active dimer; the monomeric form is less active and less stable. Monomer-monomer interactions could be mediated by the membrane-bound subunits ASA6 and ASA9, and may be further stabilized by other polypeptides such as ASA1 and ASA5. [less ▲]

In a few years, safe and definitive solutions should be ready to manage large quantities of high-level radioactive waste. Deep geological repository involving a multibarrier system constitutes one of the most promising options to isolate such waste from the human environment. In order to provide reasonable assurance of the waste isolation efficiency, it is essential to understand the behaviour of the confining geomaterials under a variety of environmental conditions. In particular, variations in temperature and humidity are two main critical aspects in the short and medium term (i.e. several thousands of years). To this end, results from a near-to-real scale experiment were studied by means of a thermo-hydro-mechanical (THM) finite element approach including a consistent thermo-plastic constitutive model for unsaturated soils. This enabled a comprehensive understanding of the behaviour of the buffer material (bentonite). [less ▲]

It is shown that, at variance with previous analyses, the MIT bag model can explain the available data of the Sivers function and satisfies the Burkardt sum rule to a few percent accuracy. The agreement is similar to the one recently found in the constituent quark model. Therefore, these two model calculations of the Sivers function are in agreement with the present experimental and theoretical wisdom. © 2009 The American Physical Society. [less ▲]

Experimental model data are compared with numerical computations of dike-break induced flows, focusing on the final steady state. An idealised scale model was designed reproducing the specific boundary conditions of dike breaks. Discharges, water levels and depth profiles of horizontal velocities were recorded and validated by numerical modeling. The latter was performed by two different models solving the two-dimensional depth-averaged shallow water equations, namely a total variation diminishing Runge-Kutta dis¬continuous Galerkin finite element method, and a finite volume scheme involving a flux vector splitting ap¬proach. The results confirmed convergence and general applicability of both methods for dike-break prob¬lems. As regards their accuracy, the basic flow pattern was satisfactorily reproduced yet with differences compared to the measurements. Hence, additional simulations by a finite volume model were performed con¬sidering various turbulence closures, wall-roughnesses as well as non-uniform Boussinesq coefficients. [less ▲]

This paper presents three HVDC modulation strategies to improve transient stability in an interconnected power system. AC variables such as rotor speeds, voltage phasors, and tieline power flows are used as input to the controller that modifies the power flow settings through the HVDC-links. The proposed techniques are tested on the IEEE 24-Bus reliability test system and critical clearing times obtained for several contingencies are analyzed. The paper shows that HVDC modulation can lead to substantial improvement in transient stability. [less ▲]

Objective The WHO recommends a daily Ca intake for postmenopausal women of 1300 mg. The objective of the present study was to assess the dietary Ca intake in European postmenopausal osteoporotic women. Design, setting and subjects Assessment of dietary Ca intake (food and supplements) was performed with a validated self-questionnaire in 8524 osteoporotic women from nine European countries (Belgium, Denmark, France, Germany, Hungary, Italy, Poland, Spain and the UK). Results Mean age of the patients was 74·2 (sd 7·1) years, mean BMI was 25·7 (sd 4·2) kg/m2. Of the study population, 37·2 % of the women took Ca supplements. The mean dietary intake of Ca was 930·7 (sd 422·9) mg/d. The lowest Ca intake was found in Hungary (586·7 (sd 319·1) mg/d) and the highest in Denmark (1145·6 (sd 463·0) mg/d). In the whole study population, only 19·1 % of the women had a dietary Ca intake >1300 mg/d. Only 17·1 % of women aged over 75 years achieved 1300 mg/d compared with 20·5 % of women aged less than 75 years (P = 0·0001 for the difference between the two groups). Conclusion Dietary intake of Ca is very low in European postmenopausal women. A greater awareness is needed to resolve this public health problem. [less ▲]
