Abstract
According the latest predictions, an increase of about two times in atmospheric CO2 concentrations, is expected to occur by the end of this century. In order to understand the effects of this atmospheric composition changes on two abundant Mediterranean halophytes (Halimione portulacoides and Spartina maritima), mesocosmos trials were performed simulating two atmospheric CO2 environments (380 ppm and 760 ppm of CO2 respectively). The two chosen halophyte species present different metabolic characteristics: H. portulacoides, is a C3 specie while S. maritima is a C4 species. Distinct feedbacks were obtained for each of the studied species. Stable Isotope discrimination showed that both species showed an enhancement of the Rubisco carboxylation capacity and photosynthetic efficiency mostly due to an increase in intracellular [CO2]. In H. portulacoides CO2 fertilization induced an enhancement of ETR and a decrease in non-photochemical quenching and in dissipated energy fluxes. On the other hand the C4 grass S. maritima, already at full capacity, showed no photosynthetic enhancement. In fact this highly productive grass presented lower photosynthetic efficiencies accompanied by increases in dissipated energy fluxes mostly due to reductions in energy flux associated with the transport of reducing power throughout the quinone pool. The accumulation of reducing power led to oxidative stress, and thus the photosynthetic ability of this grass was greatly reduced. Both these feedbacks to realistic future CO2 concentrations are important consideration for in future primary productivity models, indicating a possible reduced abundance of the pioneer S. maritima and an increased biomass spreading of the sediment stabilizer H. portulacoides, inevitably affecting the morphology and function of the salt marshes imposed by these atmospheric changes, both in terms of ecosystem functioning and loss of biodiversity.

Abstract
CD10 is a multifunctional transmembrane neutral endopeptidase (NEP) that is considered to be a reliable marker of ectopic human endometrial stroma. Available information on NEP/CD10 protein expression in animal endometria is scarce. This study focused on the immunolocalization of NEP/CD10 in the canine uterus and on its temporal changes during the estrous cycle and early pregnancy (Days 11 to 23 post-LH surge) in healthy females. NEP/CD10 expression was found in the canine endometrial stroma in all stages of the estrous cycle, showing cyclic differences both in intensity and in distribution pattern. A small population of negative stromal cells in subsurface position was also observed. This population shared some morphological characteristics with the human predecidual cells, which became positive in progesterone-associated stages of the cycle. In addition, positive immunolabeling was also observed in canine myometrial stroma. In early pregnancy, the basal glandular epithelia and the syncytium cords remained negative to this marker contrasting with the trophoblast and the lacunar epithelium. A weak to moderate intensity of immunolabeling was observed in the decidual cells, whereas stromal immunolabeling was more intense at the delimitation of the syncytium cords. In conclusion, CD10 is consistently expressed in the canine endometrial stroma and myometrium but not in the endometrial epithelia. The characteristic pattern seen in early pregnancy also suggests a role for this molecule in the process of embryo invasion at implantation.

Abstract
Lead (Pb) continues to be a major toxic metal in the environment. Pb exposure frequently occurs in the presence of other metals, such as arsenic (As) and manganese (Mn). Continued exposure to low levels of these metals may lead to long-term toxic effects due to their accumulation in several organs. Despite the recognition that metals in a mixture may alter each other's toxicity by affecting deposition, there is dearth of information on their interactions in vivo. In this work, we investigated the effect of As and Mn on Pb tissue deposition, focusing on the kidney, brain, and liver. Wistar rats were treated with eight doses of each single metal, Pb (5 mg/Kg bw), As (60 mg/L), and Mn 10 mg/Kg bw), or the same doses in a triple metal mixture. The kidney, brain, liver, blood, and urine Pb, As, and Mn concentrations were determined by graphite furnace atomic absorption spectrophotometry. The Pb kidney, brain, and liver concentrations in the metal-mixture-treated group were significantly increased compared to the Pb-alone-treated group, being more pronounced in the kidney (5.4-fold), brain (2.5-fold), and liver (1.6-fold). Urinary excretion of Pb in the metal-mixture-treated rats significantly increased compared with the Pb-treated group, although blood Pb concentrations were analogous to the Pb-treated group. Co-treatment with As, Mn, and Pb alters Pb deposition compared to Pb alone treatment, increasing Pb accumulation predominantly in the kidney and brain. Blood Pb levels, unlike urine, do not reflect the increased Pb deposition in the kidney and brain. Taken together, the results suggest that the nephro- and neurotoxicity of "real-life" Pb exposure scenarios should be considered within the context of metal mixture exposures.

Abstract
RNA interference (RNAi) has become a widely used loss-of-function tool in eukaryotes; however, the delivery of double-stranded (ds)RNA) to the target cells remains a major challenge when exploiting the RNAi-technology. In insects, the efficiency of RNAi is highly species-dependent. Yet, the mechanism of cell entry in insects has only been characterized in a cell line of the fruit fly, Drosophila melanogaster, a species that is well known to be poorly amenable to environmental RNAi. In the present paper, we demonstrate that silencing vacuolar H-ATPase 16 (vha16) and clathrin heavy chain (clath), two components of the Clathrin-dependent endocytosis pathway, together with pharmacological inhibition of scavenger receptors with polyinosine and dextran sulphate, can significantly attenuate the highly robust RNAi response in the desert locust, Schistocerca gregaria.

Abstract
Submergence is one of the major constrains affecting wetland plants, with inevitable impacts on their physiology and productivity. Global warming as a driving force of sea level rise, tend to increase the submersion periods duration. Photosynthesis biophysical probing arise as an important tool to understand the energetics underlying plant feedback to these constrains. As in previous studies with Spartina maritima, there was no inhibition of photosynthetic activity in submerged individuals. Comparing both donor and acceptor sides of the PSII, the first was more severely affected during submersion, driven by the inactivation of the OEC with consequent impairment of the ETC. Although this apparent damage in the PSII donor side, the electron transport per active reaction centre was not substantially affected, indicating that this reduction in the electron flow is accompanied by a proportional increase in the number of active reaction centres. These conditions lead to the accumulation of excessive reducing power, source of damaging ROS, counteracted by efficient energy dissipation processes and anti-oxidant enzymatic defences. This way, S. maritima appears as a well-adapted species with an evident photochemical plasticity towards submersion, allowing it to maintain its photosynthetic activity even during prolonged submersion periods.

Abstract
O presente experimento, conduzido no laboratório de ovinocultura da Universidade Federal de Santa Maria, teve como objetivo avaliar o comportamento ingestivo de cordeiros das raças Texel e Ideal, terminados em confinamento com dietas contendo diferentes teores de casca de soja em substituição da silagem de sorgo. Foram utilizados 40 cordeiros machos não castrados, sendo 20 provenientes da raça Texel e 20 da raça Ideal, desmamados aproximadamente aos 50 dias e confinados em baias individuais, distribuídos aleatoriamente em quatro grupos de acordo com o nível de inclusão de casca de soja na dieta: 0 %, 33,5 %, 66,5 % e 100 % de casca de soja em substituição a silagem de sorgo. O tempo despendido em atividades de alimentação, tempo de mastigação total e o tempo gasto por refeição diminuíram linearmente, enquanto que o período de ócio e a eficiência de alimentação e de ruminação aumentaram linearmente, com o aumento do nível de substituição de silagem de sorgo por casca de soja. Cordeiros da raça Texel permaneceram por mais tempo em atividades de ruminação e de mastigação total, gastaram mais tempo por refei-ção, permaneceram menos tempo em ócio e apresentaram menor eficiência de ruminação quando comparados com cordeiros da raça Ideal, quando confinados em fase de terminação.

Abstract
Infrared image data captured by non-mydriatic digital retinography systems often are used in the diagnosis and treatment of the diabetic macular edema (DME). Infrared illumination is less aggressive to the patient retina, and retinal studies can be carried out without pupil dilation. However, sequences of infrared eye fundus images of static scenes, tend to present pixel intensity fluctuations in time, and noisy and background illumination changes pose a challenge to most motion detection methods proposed in the literature. In this paper, we present a retinal motion detection method that is adaptive to background noise and illumination changes. Our experimental results indicate that this method is suitable for detecting retinal motion in infrared image sequences, and compensate the detected motion, which is relevant in retinal laser treatment systems for DME.

Abstract
Halimione portulacoides and Sarcocornia fruticosa commonly exhibit a reddish coloration especially in high evaporation periods, due to betacyanin production in response to stress. Although sharing the same area in salt marshes, they present different strategies to overcome salinity stress. While S. fruticosa present a dilution strategy, increasing succulence, H. portulacoides appears to have developed an ionic compartmentalization strategy. Nevertheless, there's still a decrease in the photosynthetic activity in different extents. While in S. fruticosa, the impairment of photosynthetic activity is due to a decrease in the flow from the electron transport chain to the quinone pool; in H. portulacoides the process is affected far more early, with high amounts of energy dissipated at the PSII light harvesting centers. This photosynthetic impairment leads to energy accumulation and consequently to the production of reactive oxygen species (ROS). SOD was particularly active in stressed individuals, although this increment is rather more significant in S. fruticosa than in H. portulacoides suggesting that H. portulacoides may have a maximum salt concentration at which can sustain cellular balance between ROS production and scavenging. These different ecophysiological responses have great importance while evaluating the impacts climate change driven increase of sediment salinity on halophyte physiology and on the marsh community and ecosystem services.

Abstract
Plasma treatment is a method to modify the physicochemical properties of biomaterials, which consequently may affect interactions with cells. Based on the rationale that physical cues on the surface of culture substrates and implants, such as surface roughness, have proven to alter cell behaviour, we used electrospinning to fabricate fibrous three-dimensional scaffolds made of a poly (ethylene oxide terephthalate)/poly (butylene terephthalate) copolymer to mimic the physical microenvironment of extracellular matrix and applied radio-frequency oxygen plasma treatment to create nanoscale roughness. Scanning electron microscopy (SEM) analysis revealed a fibre diameter of 5.49 ± 0.96 µm for as-spun meshes. Atomic force microscopy (AFM) measurements determined an exponential increase of surface roughness with plasma treatment time. An increase in hydrophilicity after plasma treatment was observed, which was associated with higher oxygen content in plasma treated scaffolds compared to untreated ones. A more pronounced adsorption of bovine serum albumin occurred on scaffolds treated with plasma for 15 and 30 min compared to untreated fibres. Clinically relevant human mesenchymal stromal cells (hMSCs) were cultured on untreated, 15 and 30 min treated scaffolds. SEM analysis confirmed cell attachment and a pronounced spindle-like morphology on all scaffolds. No significant differences were observed between different scaffolds regarding the amount of DNA, metabolic activity and alkaline phosphatase (ALP) activity after 7 days of culture. The amount of ALP positive cells increased between 7 and 21 days of culture on both untreated and 30 min treated meshes. In addition, ALP staining of cells on plasma treated meshes appeared more pronounced than on untreated meshes after 21 days of culture. Quantitative polymerase chain reaction showed significant upregulation of bone sialoprotein and osteonectin expression on oxygen plasma treated fibres compared to untreated fibres in basic culture medium after 7 days of culture, while no differences were observed in the expression of other osteogenic markers. At 21 days, no osteocalcin protein could be detected by ELISA at any of the substrates. In conclusion, this study shows that oxygen plasma treatment can successfully be applied to modify the nanoscale surface properties of polymeric electrospun fibre meshes, which in turn may positively affect osteogenic differentiation of hMSCs.

Abstract
We present the evolution of the full set of Einstein equations during preheating after inflation. We study a generic supersymmetric model of hybrid inflation, integrating fields and metric fluctuations in a 3-dimensional lattice. We take initial conditions consistent with Einstein's constraint equations. The induced preheating of the metric fluctuations is not large enough to backreact onto the fields, but preheating of the scalar modes does affect the evolution of vector and tensor modes. In particular, they do enhance the induced stochastic background of gravitational waves during preheating, giving an energy density in general an order of magnitude larger than that obtained by evolving the tensor fluctuations in an homogeneous background metric. This enhancement can improve the expectations for detection by planned gravitational wave observatories.

Abstract
Lipid nanoparticles are used as biocompatible carriers for several types of drugs intended for pharmaceutical, cosmetic, and biochemical purposes. The wide range of lipids and surfactants available for the production of such particles turns these carriers highly suitable for distinct applications (topical, dermal and transdermal, parenteral, pulmonary, and oral administration). This work describes the development of a special type of lipid particles, namely nanostructured lipid carriers (NLC), for minoxidil as an alternative to conventional topical alcoholic solutions. NLC were composed of stearic acid and oleic acid, being the matrix stabilized with poloxamer 188 in aqueous dispersion. To develop a suitable topical formulation, lipid dispersions were further mixed with freshly prepared Carbopol or perfluorocarbon based hydrogels. Minoxidil-loaded NLC were approximately 250 nm in size before the entrapment within the gel network and remained below 500 nm after mixing with both types of hydrogels. The occurrence of minoxidil crystallization in the aqueous phase of lipid dispersions was discarded under analysis by light microscopy and by scanning electron microscopy. Differential scanning calorimetry was used to assess the recrystallization index (i.e. measure of the percentage of lipid matrix that is crystallized) of the particles, which was shown to be 62% for minoxidil-free dispersions and 68% for minoxidil-loaded NLC dispersions. Rheological analysis of hydrogels containing NLC dispersions showed typical pseudoplastic behaviour which makes them suitable for topical purposes.

Abstract
Young onset dementia raises concern about familial and non degenerative dementias. We describe a patient with early dementia. At the age of 26, a woman developed symptoms of anorexia nervosa, at 30 a memory and attention deficit, and at 34 abnormal behavior with impulsivity, aggression, and dysexecutive disorder. At 36 she showed aphasia, stereotyped behavior, hyperreflexia, grasping reflex, urinary incontinence, myoclonus, and seizures. Blood and cerebrospinal fluid were normal. Brain computed tomography and single photon emission computed tomography showed diffuse cortico-subcortical atrophy and frontotemporoparietal hypoperfusion. A Leu424Val mutation was present in PSEN1 gene. PSEN1 mutations can produce Alzheimer's disease, frontotemporal dementia, and dementia with Lewy bodies phenotypes, or a combination of them. It has been proposed that the mutation type and location may influence the molecular pathogenesis and thus PSEN1 would represent a molecular connexion between these entities. This case shows a novel PSEN1 mutation with outstanding amnesic and frontal symptoms.

Abstract
Following the establishment of a transgenic line of tobacco (B5H) expressing the trehalose-6-phosphate synthase (TPS) gene from Arabidopsis thaliana, a preliminary immunolocalization study was conducted using leaves of adequately watered B5H and wild-type plants. Immunocytochemical staining, followed by electron microscopy showed that the enzyme could be detected in both B5H and wild-type plants at two different levels. Quantification showed the signal to be two to three times higher in transgenic plants than in the wild type. This enzyme was markedly present in the vacuoles and the cell wall, and to a lesser extent in the cytosol. Moreover, a high profusion of gold particles was detected in adjacent cells and in the sieve elements. Occasional spots were also detected in chloroplasts and the nucleus, especially in the transgenic B5H line. No labeling signal was detected in mitochondria. Protein localization seems to confirm the important role of TPS in sugar metabolism and transport through the plant, which could explain its role in plant stress tolerance. Finally, it can be expected that TPS from tobacco has a relatively high similarity to the TPS of Arabidopsis thaliana.

Abstract
SUMMARY
Directional arrays of branched microscopic setae constitute a dry adhesive on the toes of pad-bearing geckos, nature's supreme climbers. Geckos are easily and rapidly able to detach their toes as they climb. There are two known mechanisms of detachment: (1) on the microscale, the seta detaches when the shaft reaches a critical angle with the substrate, and (2) on the macroscale, geckos hyperextend their toes, apparently peeling like tape. This raises the question of how geckos prevent detachment while inverted on the ceiling, where body weight should cause toes to peel and setal angles to increase. Geckos use opposing feet and toes while inverted, possibly to maintain shear forces that prevent detachment of setae or peeling of toes. If detachment occurs by macroscale peeling of toes, the peel angle should monotonically decrease with applied force. In contrast, if adhesive force is limited by microscale detachment of setae at a critical angle, the toe detachment angle should be independent of applied force. We tested the hypothesis that adhesion is increased by shear force in isolated setal arrays and live gecko toes. We also tested the corollary hypotheses that (1) adhesion in toes and arrays is limited as on the microscale by a critical angle, or (2)on the macroscale by adhesive strength as predicted for adhesive tapes. We found that adhesion depended directly on shear force, and was independent of detachment angle. Therefore we reject the hypothesis that gecko toes peel like tape. The linear relation between adhesion and shear force is consistent with a critical angle of release in live gecko toes and isolated setal arrays, and also with our prior observations of single setae. We introduced a new model,frictional adhesion, for gecko pad attachment and compared it to existing models of adhesive contacts. In an analysis of clinging stability of a gecko on an inclined plane each adhesive model predicted a different force control strategy. The frictional adhesion model provides an explanation for the very low detachment forces observed in climbing geckos that does not depend on toe peeling.

Abstract
2509 Background: WM represents a lymphoplasmacytic lymphoma characterized by a monoclonal IgM gammopathy and possesses a mast cell component that may contribute to its pathogenesis. The tumor necrosis factor (TNF) receptor family member, CD27, is a transmembrane co-stimulatory molecule that is also secreted in a soluble form (sCD27). Recent evidence has suggested that interactions between CD27 and its TNF-like ligand, CD70, play a critical role in regulating B-cell activation and survival, and therefore, may provide a viable therapeutic target for the treatment of WM. Methods: Patients with the consensus panel diagnosis of WM who provided written consent were evaluated. ELISA assay kits were obtained from Bender MedSystems. Flow cytometric analysis, RT-PCR, and calcein ADCC assays were performed as previously described (Santos et al, in press). Results: By ELISA, WM patients displayed dramatically higher levels of sCD27 in their sera (median 7.45, range 0–19.42 U/ml) versus healthy donors (median 0, range 0–2.78 U/ml; p = 2.5 × 10−7). CD27 was expressed in 7/7 patients using RT-PCR analysis, and on the tumor cell surface of 5/12 patients. CD70, the target for CD27, was widely expressed on tumor cells (6/6) and mast cells (10/11) using flow cytometric analysis. To define the functional role of sCD27 in WM, we cultured BCWM.1 (CD27−CD70+) WM cells, LAD1 (CD27−CD70+) mast cells, and primary tumor and mast cells (CD70+) isolated from WM patients with sCD27 (0.1–50 ug/mL), and observed no effect on their proliferation or induction of apoptosis. However, culture of LAD1 and primary WM mast cells (10/10) with sCD27 resulted in marked upregulation of two TNF family ligands which support the growth and survival of WM cells: CD40L (CD154) and a proliferation induction ligand (APRIL). Importantly, the anti-CD70 mAb SGN-70 (1 ug/ml) inhibited this upregulation by sCD27, establishing the specificity of the CD27-CD70 interaction. In addition, SGN-70 demonstrated significant ADCC against BCWM.1 WM cells at dose levels up to 20 ug/ml. Conclusions: Taken together, these studies suggest a novel functional role for sCD27 in the pathogenesis of WM, and demonstrate the feasibility of targeting CD70 and sCD27-CD70 interactions with the SGN-70 monoclonal antibody.

Abstract
INTRODUCTION The quality of life (QOL) of patients with morbid obesity (MO) is reduced given the restrictions it imposes. Bariatric surgery is considered an efficient treatment for MO as it leads to marked and progressive weight reduction. Weight loss, appropriate nutritional advice and follow up may induce significant improvement in QOL. AIM To evaluate the degree of QOL in patients with MO before and after bariatric, surgery (Fobi-Capella reducing gastroplasty). CASES. MATERIAL AND METHODS 95 morbidly obese(BMI > 40 kg/m2) or moderately obese (BNI 35 - 39 kg/m2) patients with co-morbidities were seen, followed up and given advice by the Nutrition, Psychology, Endocrinology and Surgery staff at the Federal University of Bahia Hospital. Group I included 66 subjects at the pre-surgical stage and Group II was composed of 29 other patients in a late postsurgical phase. Group II patients were seen at 6, 12 and more months after bariatric surgery. The medical outcomes study Short-Form Health Survey (SF-36) was the instrument used to evaluate QOL in this study. Data were analyzed using the Mann-Whitney non-parametric method and the SPSS program. RESULTS A statistically significant improvement in QOL was detected in the aspects of general health, functional ability and vitality. A progressive improvement in physical conditioning was particularly observed in the patients who had had bariatric surgery less than 6 months before, between 6 and 12 months and more than 12 months before. Small changes in subjective features were seen. An improvement in social aspects was observed after a post surgical fall. This explains why do not changes appear when pre and post surgical patients are compared. CONCLUSIONS Fobi-Capella bariatric surgery for our patients with MO or with co-morbidities associated moderate obesity resulted in QOL improvement, and gradual but marked improvements in physical condition over time.

Abstract
BACKGROUND The anti-CD20 monoclonal antibody rituximab is an important therapeutic in Waldenstrom's macroglobulinemia (WM), producing response rates of 50-70%. Responses, which are based on serum IgM levels, have typically been evaluated at 12 weeks. Paradoxically, we have observed that serum IgM levels can abruptly rise following rituximab therapy in patients with WM, and can often lead to morbidity on the basis of hyperviscosity. PATIENTS AND METHODS Eleven WM patients with CD20+ tumor cells who received rituximab at our Institution and had serum IgM levels measured within a 12-week period following start of therapy were evaluated. Therapy consisted of four weekly infusions of rituximab at 375 mg/m(2). Pre- and post-therapy serum IgM levels were determined by nephelometry and corresponding serum viscosity levels were determined by viscometry. RESULTS Ten of the 11 patients demonstrated an abrupt rise in serum IgM levels, with a >25% increase occurring in eight (73%) patients. Mean serum IgM levels for all 10 spiking patients rose from 4370 (range, 655-7940) to a peak of 5865 (range, 872-11 800) mg/dl (P=0.004), which occurred at a mean of 4 (range, 1-8) weeks following initiation of therapy. Mean serum viscosity levels also increased from 3.5 to 5.6 centipoise (CP) (P=0.09) in eight patients for whom pre- and post-therapy studies were obtained. A subdural hemorrhage occurred in one patient when serum IgM levels rose from 7530 to 11 800 mg/dl, and serum viscosity increased from 3.9 to 10.1 CP. Two other spiking patients with pre-therapy IgM levels of >5000 mg/dl experienced worsening headaches and/or epistaxis attributed to increasing serum viscosity. CONCLUSIONS Abrupt increases in serum IgM levels commonly occur following rituximab therapy in WM. Careful clinical and laboratory monitoring is warranted, particularly if patients have pre-therapy serum IgM levels of >5000 mg/dl. The mechanism of this effect is under active investigation, and may be related to CD20 signaling triggered by rituximab.
