Abstract
The 7-item Functionality Appreciation Scale (FAS) measures the extent of an individual's appreciation of their body for what it can do and is capable of doing. Although the FAS has been widely used in diverse linguistic contexts, it has not been previously translated into Spanish. Here, we examined the psychometric properties of a novel Spanish translation of the FAS in Colombian adults. A total of 1420 university students from Colombia (804 women, 616 men) completed the FAS, as well as additional validated measures. Exploratory and confirmatory factor analyses in separate subsamples supported a unidimensional model of FAS scores. The FAS evidenced scalar invariance across gender identity, with men having significantly higher FAS scores than women (Cohen's d = 0.18). FAS scores were also found to have adequate composite reliability, as well as adequate convergent (significant associations with body appreciation, appearance evaluation, and eating disorder psychopathology) and concurrent validity (significant associations with self-esteem, life satisfaction, and gratitude). Functionality appreciation incrementally predicted life satisfaction in women, but not in men. Overall, these results suggest that the Spanish FAS is a psychometrically valid and reliable tool for the assessment of functionality appreciation in university-aged populations from Colombia.

Abstract
OBJECTIVE To ascertain maternal and perinatal outcomes of monochorionic twin pregnancies complicated by twin-twin transfusion syndrome (TTTS) treated with the Solomon technique compared with selective fetoscopic laser photocoagulation (SFLP) of placental anastomoses. METHODS MEDLINE, EMBASE and The Cochrane Library were searched to identify relevant studies. The outcomes observed were perinatal loss and survival, preterm prelabor rupture of membranes (PPROM), preterm birth (PTB), gestational age (GA) at delivery, interval between laser treatment and delivery, maternal bleeding, septostomy or chorioamniotic separation, placental abruption, twin anemia-polycythemia sequence (TAPS), recurrence of TTTS, neonatal morbidity and neurological morbidity. Random-effects head-to-head meta-analyses were used to analyze the data. Pooled odds ratios (OR) and mean differences (MD) and their 95% CIs were calculated. RESULTS Nine studies were included in the systematic review. There was generally no difference in the main maternal and pregnancy characteristics between pregnancies treated using the Solomon technique and those treated using SFLP of placental anastomoses. The risks of fetal loss (pooled OR, 0.69 (95% CI, 0.50-0.95); P = 0.023), neonatal death (pooled OR, 0.37 (95% CI, 0.16-0.84); P = 0.018) and perinatal loss (pooled OR, 0.56 (95% CI, 0.38-0.83); P = 0.004) were significantly lower in pregnancies treated using the Solomon technique than in those treated with SFLP. Likewise, pregnancies treated using the Solomon technique had a significantly higher chance of survival of at least one twin (pooled OR, 2.31 (95% CI, 1.03-5.19); P = 0.004) and double survival (pooled OR, 2.18 (95% CI, 1.29-3.70); P = 0.001). There was no difference in the risk of PPROM (P = 0.603), PPROM within 10 days from laser surgery (P = 0.982), PTB (P = 0.207), maternal bleeding (P = 0.219), septostomy or chorioamniotic separation (P = 0.224) or chorioamnionitis (P = 0.135) between the two groups, while the risk of placental abruption was higher in pregnancies treated using the Solomon technique (pooled OR, 2.90 (95% CI, 1.55-5.44); P = 0.001). In the Solomon technique group, pregnancies delivered at a significantly earlier GA than did those treated with SFLP (pooled MD, -0.625 weeks (95% CI, -0.90 to -0.35 weeks); P < 0.001), while there was no difference in the interval between laser treatment and delivery (P = 0.589). The rate of recurrence of TTTS was significantly lower in pregnancies undergoing the Solomon technique (pooled OR, 0.43 (95% CI, 0.22-0.81); P < 0.001), while there was no difference in the risk of TAPS between the two groups (P = 0.792). Finally, there was no difference in the overall risk of neonatal morbidity (P = 0.382) or neurological morbidity (P = 0.247) between the two groups. CONCLUSIONS Monochorionic twin pregnancies complicated by TTTS undergoing laser treatment using the Solomon technique had a significantly higher survival rate and lower recurrence rate of TTTS but were associated with an increased risk of placental abruption and earlier GA at delivery compared to those treated with SFLP. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVES This study aims to evaluate the prognostic value of emergency blood test results in patients with acute ischaemic stroke. METHODS We evaluated 592 prospectively patients with neuroimaging-confirmed ischaemic stroke admitted to our stroke unit between 2015 and 2018. We gathered emergency blood test results and calculated the neutrophil-to-lymphocyte ratio and the neutrophil-to-platelet ratio (neutrophils × 1.000/platelets). The association between blood test results and functional prognosis (as measured with the modified Rankin Scale) and such complications as haemorrhagic transformation was evaluated by logistic regression analysis. The additional predictive value of blood test parameters was assessed with receiver operating characteristic curves and the net reclassification index. RESULTS An neutrophil-to-lymphocyte ratio ≥ 3 at admission was associated with a two-fold increase in the risk of functional dependence at 3 months (OR: 2.24; 95% CI: 1.35-3.71) and haemorrhagic transformation (OR: 2.11; 95% CI: 1.09-4.05), while an neutrophil-to-lymphocyte ratio ≥ 3.86 resulted in an increase of 2.4 times in the risk of mortality at 3 months (OR: 2.41; 95% CI: 1.37-4.26) after adjusting for the traditional predictors of poor outcomes. Patients with neutrophil-to-platelet ratio ≥ 32 presented 3 times more risk of haemorrhagic transformation (OR: 3.17; 95% CI: 1.70-5.92) and mortality at 3 months (OR: 3.07; 95% CI: 1.69-5.57). Adding these laboratory parameters to standard clinical-radiological models significantly improved discrimination and prognostic accuracy. CONCLUSIONS Basic blood test parameters provide important prognostic information for stroke patients and should therefore be analysed in combination with standard clinical and radiological parameters to optimise ischaemic stroke management.

Abstract
BackgroundBaricitinib (BARI), an oral selective JAK 1/2 inhibitor, is approved for treating adults with moderate to severe active rheumatoid arthritis (RA). RA-BE-REAL is a 3-year, multinational, prospective, observational study of adult patients with RA evaluating time to discontinuation of initial RA treatment for all causes (excluding sustained clinical response) over 24 months (M).ObjectivesThis analysis reports time to discontinuation in the European (France, Germany, Italy, Spain, UK) subgroup, treated with either BARI, biologic (b) disease-modifying anti-rheumatic drugs (DMARDs) or any other targeted synthetic (ts)DMARDs, as well as, the effectiveness of RA treatment, at 12M.MethodsIn the two cohorts, patients were initiated with BARI 2-mg or 4-mg (cohort A), or any bDMARD or tsDMARD (b/tsDMARDs; cohort B). Treatment initiation and changes are at the discretion of the patient or physician. Response rates for remission, low disease activity (LDA), moderate disease activity (MDA) or high disease activity (HDA) were determined using the Clinical Disease Activity Index (CDAI) at 12M. Quality of life using the EQ-5D-5L and patient reported outcome (PRO) measures for pain (pain visual analogue scale; VAS) and physical functioning (Health Assessment Questionnaire Disability Index; HAQ-DI) were also assessed at 12M. This pre-specified interim analysis reports descriptive 12M data using summary statistics, without any inferential testing.ResultsThis analysis involved 1073 adult RA patients with a mean age (standard deviation; SD) of 59.1 (13.2) (cohort A) and 57.0 (13.9) yrs (cohort B), respectively, and a mean disease duration (SD) of 10.0 (9.1) (cohort A) and 8.9 (9.6) yrs (cohort B), respectively. At baseline, 50.9% of patients in cohort A and 31.2% in cohort B initiated treatment as a monotherapy. At 12M, 26.7% of patients in cohort A and 44.1% of patients in cohort B had discontinued treatment. The most common reason for discontinuation in both cohorts was primary non-response. At 12M, 24.1% of patients in cohort A and 16.6% in cohort B achieved CDAI remission (Figure 1). The mean CDAI reduction was -14.5 and -12.0, respectively in cohorts A and B. Mean reductions from baseline in physician global assessment (PhGA) and in patient global assessment (PGA) were -3.4 and -2.5, respectively in cohort A and -3.0 and -2.1, respectively in cohort B. Improvements from baseline in EQ-5D-5L, HAQ-DI, and pain (VAS) were reported in both cohorts at 12M. The mean pain (VAS) reduction from baseline was -24.6 and -19.3 in cohort A and cohort B, respectively.Figure 1.Percentage of pts in cohorts A and B achieving remission and LDA at 12MConclusionThe majority of BARI-treated patients were in remission or had low disease activity and continued treatment at 12M.Table 1.Disease activity and patient reported outcomes at baseline and 12MCohort A BaricitinibCohort B b/tsDMARDsBaseline12MCFBBaseline12MCFBCDAI24.0 (11.7)9.1 (8.2)-14.5 (12.4)23.8 (12.4)10.7 (9.8)-12.0 (12.6)SJC5.2 (4.8)1.3 (2.4)-3.9 (4.8)4.7 (4.9)1.3 (2.8)-3.0 (4.6)TJC7.3 (6.1)2.2 (3.6)-4.7 (6.0)7.8 (6.5)3.0 (4.8)-4.0 (6.1)PhGA5.6 (2.0)2.3 (2.1)-3.4 (2.5)5.5 (2.1)2.5 (2.1)-3.0 (2.6)PGA5.9 (2.3)3.4 (2.5)-2.5 (2.9)5.8 (2.4)3.8 (2.6)-2.1 (3.0)HAQ-DI1.4 (0.7)1.0 (0.8)-0.4 (0.6)1.3 (0.7)1.0 (0.8)-0.3 (0.6)Pain (VAS)59 (23.1)33.2 (26.2)-24.6 (28.7)56.5 (24.3)36.6 (26.5)-19.3 (30.4)EQ-5D-5L0.5 (0.3)0.7 (0.2)0.1 (0.3)0.5 (0.3)0.7 (0.2)0.1 (0.3)Values represent observed mean (SD)b/tsDMARDs; biologic/targeted synthetic disease-modifying anti-rheumatic drugs, CFB; change from baseline, CDAI; clinical disease activity index, SJC; swollen joint count, TJC; tender joint count, P(h)GA; patient (physician) global assessment of disease activity, HAQ-DI; health assessment questionnaire disability index, VAS; visual analogue scale (mm), EQ-5D-5L; European quality of life 5 dimensions 5 levelsDisclosure of InterestsRieke Alten Speakers bureau: Eli Lilly and Company, Pfizer, Galapagos, Consultant of: Eli Lilly and Company, Pfizer, Galapagos, Grant/research support from: Eli Lilly and Company, Pfizer, Galapagos, Gerd Rüdiger Burmester Speakers bureau: Amgen, AbbVie, BMS, Galapagos, Eli Lilly and Company, MSD, Pfizer, Roche, Sanofi, Consultant of: Amgen, AbbVie, BMS, Galapagos, Eli Lilly and Company, MSD, Pfizer, Roche, Sanofi, Marco Matucci Cerinic Speakers bureau: Biogen, Eli Lilly and Company, Grant/research support from: Actelion, Biogen, Novartis, MSD, Andrew Ostor Consultant of: AbbVie, BMS, Roche, Janssen, Eli Lilly and Company, Novartis, Pfizer, UCB, Gilead, Paradigm, Liliana Zaremba-Pechmann: None declared, Marta Herrera Shareholder of: Eli Lilly and Company, Employee of: Eli Lilly and Company, Kathy Gibson Speakers bureau: UCB, Consultant of: Janssen, Novartis, Grant/research support from: Novartis, Employee of: Eli Lilly and Company, Tamas Treuer Shareholder of: Eli Lilly and Company, Employee of: Eli Lilly and Company, Jens Gerwien Shareholder of: Eli Lilly and Company, Employee of: Eli Lilly and Company, Bruno Fautrel Consultant of: AbbVie, Biogen, BMS, Celgene, Janssen, Eli Lilly and Company, Medac, MSD, Nordic Pharma, Novartis, Pfizer, Roche, Sanofi-Aventis, SOBI, UCB, Grant/research support from: AbbVie, MSD, Pfizer, Eli Lilly and Company

Abstract
Temporal plus epilepsy is defined as focal epilepsy in which the primary epileptogenic area extends beyond the temporal lobe. It involves the neighboring regions such as the insula, the suprasilvian opercular cortex, the orbitofrontal cortex and the temporo-parieto-occipital junction. The objective of this review is to provide an update in temporal plus epilepsy. A previous history of brain trauma, a history of tonic clonic seizures, and previous central nervous system infection are risk factors. They likely allowed the generation of complex hippocampal and extrahypocampic neural networks. Clinical manifestations will depend on the location of the epileptogenic zone as well as the rapid propagation into temporal mesial structures. Video-electroencephalography usually shows involvement of the temporal lobe, with rapid propagation into the perisilvian, orbitofrontal or temporo-parieto-occipital regions. The magnetoelectroencephaography has lesser muscle contamination and could be considered as a biomarker of early states in the diagnosis process. Brain MRI is usually negative or shows non-specific mesial temporal abnormalities. Stereoelectroencephalography is the invasive method of choice. Temporal plus epilepsy is considered to be the most common cause of temporal lobe epilepsy surgery failure and represents up to 30%.

Abstract
Sub-monolayer (SML) deposition of InSb within InAs matrix by migration enhanced epitaxy tends to form type II SML nanostructures offering efficient light emission within the mid-infrared (MIR) range between 3 and 5 μm. In this work, we report on the Sb distribution in InSb/InAs SML nanostructures with InAs cap layers grown at temperatures lower than that associated with the under-grown InSb active layer. Analysis by transmission electron microscopy (TEM) in 002 dark field conditions shows that the reduction in the growth temperature of the InAs cap layer increases the amount of Sb deposited in the layers, in good agreement with the x-ray diffraction results. TEM micrographs also show that the layers are formed by random InSbAs agglomerates, where the lower cap temperature leads to a more continuous InSb layer. Quantitative atomic column resolved high angle annular dark field-scanning (S)TEM analyses also reveal atomic columns with larger composition of Sb for the structure with the lowest InAs cap layer temperature. The dependence of the Sb distribution on InAs cap growth temperature allows tuning the corresponding emission wavelength in the MIR range, as shown by the photoluminescence emission spectra.

Abstract
InSb/InAs sub-monolayer (SML) nanostructures such as SML quantum dots offer sharper emission spectra, a better modal gain and a larger modulation bandwidth compared to its Stranski-Krastanov counterpart. In this work, the Sb distribution of SML InSb layers grown by migration enhanced epitaxy has been analyzed by transmission electron microscopy (TEM) techniques. The analysis of the material by diffraction contrast in 002 dark field conditions and by atomic column resolved high angle annular dark field-scanning TEM reveal the presence of a low Sb content InSbAs continuous layer with scarce Sb-rich InSbAs agglomerates. The intensity profiles obtained by both techniques point to Sb segregation during growth. This segregation has been quantified using the Muraki segregation model obtaining a high segregation coefficient R of 0.81 towards the growth direction. The formation of a continuous InSbAs wetting layer as a result of a SML deposition of Sb on the InAs surface is discussed.

Abstract
Background Determine the behavior of the maxillofacial trauma of adults treated in 3 tertiary care centers in the central zone of Chile. Material and Methods Descriptive, cross-sectional, multicenter study, based on the prospective records of maxillofacial trauma cases attended between May 2016 and April 2017 by dental and maxillofacial clinical teams of Adult Emergency Units of hospitals Dr. Sótero del Río (metropolitan region), Carlos Van Buren and Dr. Gustavo Fricke (region V). Age, sex, date of occurrence, type of trauma according to ICD-10, etiology, legal medical prognosis and associated injuries were recorded, stratifying by sex and age. Chi square and unpaired Wilcoxon tests were used to compare by groups. Results 2.485 cases and 3.285 injuries were investigated. The male: female ratio was 1.7: 1 with age under 30 predominant, followed by older adults. Variability was observed in the yearly, weekly and daily presentation. The highest frequencies were in January and September, weekends and at night. The main etiologies were violence (42.3%), falls (13.1%) and road traffic crashes (12.9%) with differences by age and sex (p<0.05). 31,9% of the injuries occurred in hard tissue, being fractures in nasal bones predominant (S02.2). Conclusions The profile of the maxillofacial trauma in Chile seems to be mixed by age, affecting young people and the elderly. The male sex predominates; the main cause, which varies by age group, is violence. Their surveillance is possible from hospital emergency records. Key words:Maxillofacial trauma, emergency department, multicenter study.

Abstract
Polyethylene glycol (PEG) assembled on the surface of two-dimensional tungsten disulfide (WS2) into a limited number of nanoislands (NIs), nanoshells (NSs), and granular nanoparticulates (GNPs) depending on its chain length. NI assemblies showed a nonmeasurable shift of photoluminescence (PL) and the A and B absorption peaks of WS2. This confirmed that the electronic doping by thiol is not effective. The PEG NS assembly displayed a smaller red shift of the PL and a slight decrease of the energy difference between the A and B absorption peaks of WS2. However, increasing the dielectric function on the surface of WS2 has a small influence on their optical properties. The PEG NP assembly on WS2 exhibited a significant red shift of the PL spectrum and a large decrease of the energy difference between A and B absorption peaks. Deforming the WS2 sheet by the PEG NP assembly decreased the orbital coupling and lowered the electronic direct band gap significantly. Raman bands of WS2 are shifted to a higher frequency on improving its mechanical strength after the PEG assembly.

Abstract
Lead halide (APbX3) perovskites, in polycrystalline thin films but also perovskite nanoparticles (NPs) has demonstrated excellent performance to implement a new generation of photovoltaic and photonic devices. The structural characterization of APbX3 thin films using (scanning) transmission electron microscopy ((S)TEM) techniques can provide valuable information that can be used to understand and model their optoelectronic performance and device properties. However, since APbX3 perovskites are soft materials, their characterization using (S)TEM is challenging. Here, we study and compare the structural properties of two different metal halide APbX3 perovskite thin films: bulk CH3NH3PbI3 prepared by spin-coating of the precursors in solution and CsPbBr3 colloidal NPs synthetized and deposited by doctor blading. Both specimen preparation methods and working conditions for analysis by (S)TEM are properly optimized. We show that CH3NH3PbI3 thin films grown by a one-step method are composed of independent grains with random orientations. The growth method results in the formation of tetragonal perovskite thin films with good adherence to an underlying TiO2 layer, which is characterized by a photoluminescence (PL) emission band centered at 775 nm. The perovskite thin films based on CsPbBr3 colloidal NPs, which are used as the building blocks of the film, are preserved by the deposition process, even if small gaps are observed between adjacent NPs. The crystal structure of CsPbBr3 NPs is cubic, which is beneficial for optical properties due to its optimal band gap. The absorption and PL spectra measured in both the thin film and the colloidal solution of CsPbBr3 NPs are very similar, indicating a good homogeneity of the thin films and the absence of aggregation of NPs. However, a particular care was required to avoid long electron irradiation times during our structural studies, even at a low voltage of 80 kV, as the material was observed to decompose through Pb segregation.

Abstract
The influence of the neighbouring atomic-columns in determining the composition at atomic column scale of quaternary semiconductor compounds, using simulated HAADF-STEM images is evaluated. The InAlAsSb alloy, a promising material in the photovoltaic field, is considered. We find that the so called 'crosstalk' effect plays an important role for the aimed compositional determination. The intensity transfer is larger from neighbouring atomic columns with higher average Z, and towards atomic columns with smaller Z. Our results show that in order to obtain precise information on the column composition, the HAADF-STEM intensities of both columns need to be taken into account simultaneously.

Abstract
PURPOSE Breast cancer patients receiving hormonal therapies face risks of relapse, increased rates of cardiovascular events, and toxicities of therapy such as aromatase inhibitor (AI)-associated musculoskeletal symptoms (AIMSS). C-reactive protein (CRP), a marker for inflammation, is associated with breast cancer outcomes. We evaluated whether the olive-derived polyphenol hydroxytyrosol combined with omega-3 fatty acids and curcumin would reduce CRP and musculoskeletal symptoms in breast cancer patients receiving adjuvant hormonal therapies. EXPERIMENTAL DESIGN This prospective, multicenter, open-label, single arm, clinical trial enrolled post-menopausal breast cancer patients (n = 45) with elevated C-reactive protein (CRP) taking predominantly aromatase inhibitors to receive a combination of hydroxytyrosol, omega-3 fatty acids, and curcumin for 1 month. CRP, other inflammation-associated cytokines, and pain scores on the Brief Pain Inventory were measured before therapy, at the end of therapy and 1 month after completion of therapy. RESULTS CRP levels declined during the therapy [from 8.2 ± 6.4 mg/L at baseline to 5.3 ± 3.2 mg/L (p = 0.014) at 30 days of treatment], and remained decreased during the additional 1 month off therapy. Subjects with the highest baseline CRP levels had the greatest decrease with the therapy. Pain scores also decreased during the therapy. There were no significant adverse events. CONCLUSIONS The combination of hydroxytyrosol, omega-3 fatty acids, and curcumin reduced inflammation as indicated by a reduction in CRP and reduced pain in patients with aromatase-induced musculoskeletal symptoms. Longer studies comparing this combination to other anti-inflammatories in larger groups of patients with clinical outcome endpoints are warranted.

Abstract
Con el objeto de describir la relación entre las variables climáticas y las respuestas fisiológicas, 20 ovejas fueron asignadas a: Con Sombra (CS): sombra artificial (12:00 - 14:00 h) en corral con techo de malla sombra (70%); Sin Sombra (SS): sin ofrecimiento de sombra. Se determinó radiación solar (RS; W/m2), temperatura ambiental (°C), humedad relativa (%), temperatura de globo negro (TGN; °C) e índice de temperatura-humedad (ITH; unidades), temperatura superficial (TS; °C; termómetro infrarrojo), temperatura corporal (TC; °C; termómetro digital), frecuencia respiratoria (FR; mov/min; observación directa) y coeficiente de tolerancia al calor (CTC; unidades) (PROC MIXED; SAS).Adicionalmente, los datos fueron analizados por componentes principales (InfoStat/E, 2008).CS presenta una menor TS (35,9) en comparación con SS (38,9; P ≤ 0,01); igual ocurre en TC (P ≤ 0,01). La FR en CS (112,3) fue superior a SS (139,6; P ≤ 0,01). El CTC fue mayor en SS (7,8) vs. CS (5,8; P ≤ 0,01), indicando mejor bienestar térmico en CS. La TS en lomo, cadera y/o costado presenta alta relación con TC. TGN > 42,8 y de RS > 529,1 podrían indicar reducciones del bienestar térmico. Basado en la TC y FR, el punto de quiebre del ITH en ovinos es > 80.

Abstract
The Bi content in GaAs/GaAs1 - xBi x /GaAs heterostructures grown by molecular beam epitaxy at a substrate temperature close to 340 °C is investigated by aberration-corrected high-angle annular dark-field techniques. The analysis at low magnification of high-angle annular dark-field scanning transmission electron microscopy images, corroborated by EDX analysis, revealed planar defect-free layers and a non-homogeneous Bi distribution at the interfaces and within the GaAsBi layer. At high magnification, the qHAADF analysis confirmed the inhomogeneous distribution and Bi segregation at the GaAsBi/GaAs interface at low Bi flux and distorted dumbbell shape in areas with higher Bi content. At higher Bi flux, the size of the Bi gathering increases leading to roughly equiaxial Bi-rich particles faceted along zinc blende {111} and uniformly dispersed around the matrix and interfaces. FFT analysis checks the coexistence of two phases in some clusters: a rhombohedral pure Bi (rh-Bi) one surrounded by a zinc blende GaAs1 - xBi x matrix. Clusters may be affecting to the local lattice relaxation and leading to a partially relaxed GaAsBi/GaAs system, in good agreement with XRD analysis.

Abstract
Senegalese sole is one of the most promising fish species cultivated in the Southern European countries. This study was aimed at assessing the effects of microalgae biomass added to diets for Senegalese sole juveniles on fish growing and condition status. Three isoproteic (52%) and isolipidic (10%) were formulated containing 15% Tisochrysis lutea (TISO), Nannochloropsis gaditana (NAN), or Scenedesmus almeriensis (SCE) biomass, respectively. An experimental microalgae-free diet (CT) and a commercial diet (COM) were used as controls. Fish were fed at 3% of their body weight for 85 days. Final body weight of fish fed microalgae-supplemented diets did not differ from group fed CT diet. Fish-fed CT, TISO, NAN, and SCE showed higher growth performance and nutrient utilization figures than specimen-fed COM diet. The highest carcass lipid content was found in COM group (141 g kg-1), and no differences were observed in body protein content. Ash was significantly higher in TISO, NAN, and SCE groups compared to fish-fed CT. Muscle EPA and DHA contents were not modified owing to the different dietary treatments. The n3/n6 and EPA/DHA ratios in muscle were similar in all the experimental groups. The quantification of digestive proteolytic activities did not differ among experimental groups, although differences in the protease pattern in digestive extracts by zymography were revealed in those fish fed on COM diet. Both α-amylase activity in the intestinal lumen and leucine aminopeptidase in the intestinal tissue were significantly lower in COM fish. Specimens fed on SCE diet showed a higher leucine aminopeptidase activity associated to the intestinal tissue compared to NAN-fed fish (0.40 and 0.25 U g tissue-1, respectively). The ultrastructural study revealed that the dietary inclusion of algal biomass, especially T. lutea and N. gaditana, had a positive impact on the absorptive capacity of the intestinal mucosa. The highest values for the parameters microvilli length and microvilli absorption surface were observed in fish fed on NAN diet (1.99 μm and 45.93 μm2, respectively). Even though further studies aimed at optimizing commercial formulas for Senegalese sole are required prior to any large-scale practical utilization, the results obtained clearly suggest the potential of microalgae as dietary ingredients for this fish species.

Abstract
PURPOSE Currently there is little information available about the corneal thickness values of healthy emmetropic subjects. Therefore, the authors decided to analyze the corneal thickness in healthy emmetropic subjects. METHODS The authors analyzed the difference in thickness values between the thinnest corneal site and the central and paracentral cornea in 124 eyes of 124 healthy emmetropic white subjects. RESULTS The mean difference between the thinnest site of the cornea and the thickness values obtained in the areas analyzed was as follows: 12+/-6 microm center; 140+/-19 microm superonasal; 133+/-23 microm nasal; 117+/-26 microm inferonasal; 122+/-19 microm superotemporal ; 89+/-22 microm temporal; and 99+/-29 microm inferotemporal (p<0.001; one way analysis of variance test). CONCLUSIONS In healthy emmetropic white subjects the thinnest site of the cornea is statistically lower than the central and paracentral cornea.

Abstract
Uterine acute post-breeding inflammation is a physiological tissue response to the entry of exogenous elements, with persistent endometritis being the main pathology responsible for subfertility in the mare (Equus ferus caballus; Linnaeus, 1758). Mares can be classified as susceptible or resistant to endometritis according to their ability to remove intrauterine fluid within 48 hr after experimental inoculation. Endometrial biopsy is a technique that is commonly used to establish the degree of lesions that can affect the fertility of the mare. Endometrial histomorphometry is an objective and highly precise diagnostic method. The aim of this study was to compare, during oestrus, the endometrial histomorphometry of mares previously classified as susceptible (SM) or resistant (RM) to endometritis. Endometrial biopsies from 24 mares at the oestrus phase of the cycle were obtained. For the histomorphometric analysis, samples were histologically processed and subjected to routine Haematoxylin-Eosin staining. For the evaluation, the variables were considered as follows: 1-Height of the lining and glandular epithelia (Lining SM = 15.9 μm vs. RM = 13.3 μm; Glandular SM = 15.0 μm vs. RM = 13.0 μm); 2-Perpendicular diameters of endometrial glands (SM = 51.3 μm vs. RM = 44.8 μm); 3-Number of endometrial glands per field (SM = 24.8 glands/field vs. RM = 20.5 glands/field). The results from this study suggest the existence of a relationship between the studied characteristics and the susceptibility/resistance to post-breeding endometritis in mares. Thus, increased epithelial height, greater glandular density and greater development of the glands during oestrus would be related to a higher susceptibility to endometritis.

Abstract
Oral infections caused by Candida species, the most commonly isolated human fungal pathogen, are frequently associated with biofilms. Although Candida albicans is the predominant organism found in patients with oral thrush, a biofilm infection, there is an increasing incidence of oral colonization and infections caused by non- albicans Candida species, including C. glabrata, C. dubliniensis, and C. tropicalis, which are frequently more resistant to antifungal treatment. While single-species Candida biofilms have been well studied, considerably less is known about the dynamics of mixed- Candida species biofilms and how these dynamics are altered by antifungal treatment. To address these questions, we developed a quantitative polymerase chain reaction-based approach to determine the precise species composition of mixed- Candida species biofilms formed by clinical isolates and laboratory strains in the presence and absence of clinically relevant concentrations of 3 commonly used antifungals: fluconazole, caspofungin, and amphotericin B. In monospecies biofilms, fluconazole exposure favored growth of C. glabrata and C. tropicalis, while caspofungin generally favored significant growth of all species to a varying degree. Fluconazole was not effective against preformed mixed- Candida species biofilms while amphotericin B was potent. As a general trend, in mixed- Candida species biofilms, C. albicans lost dominance in the presence of antifungals. Interestingly, presence in mixed versus monospecies biofilms reduced susceptibility to amphotericin B for C. tropicalis and C. glabrata. Overall, our data suggest that antifungal treatment favors the growth of specific non- albicans Candida species in mixed- Candida species biofilms.

Abstract
Immunobiotic lactic acid bacteria have become an interesting alternative for the prevention of respiratory infections. Previously, we demonstrated that the nasal administration of Lactobacillus rhamnosus CRL1505, during repletion of malnourished mice, resulted in diminished susceptibility to the challenge with the respiratory pathogen Streptococcus pneumoniae. Considering the known alterations induced by malnutrition on T lymphocytes and the importance of this cell population on the protection against respiratory pathogens, we aimed to study the effect of L. rhamnosus CRL1505 nasal administration on the recovery of T cell-mediated defences against pneumococcal infection in malnourished mice under nutritional recovery. Malnourished mice received a balanced conventional diet (BCD) for seven days or BCD for seven days with nasal L. rhamnosus CRL1505 supplementation during last two days of the treatment. After the treatments mice were infected with S. pneumoniae. Flow cytometry studies were carried out in bone marrow, thymus, spleen and lung to study T cells, and Th1/Th2 cytokine profiles were determined in broncho-alveolar lavages and serum. The administration of CRL1505 strain to malnourished mice under recovery reduced quantitative and qualitative alterations of CD4+ T cells in the bone marrow, thymus, spleen and lung induced by malnutrition. In addition, CRL1505 treatment augmented Th2-cytokines (interleukin 10 and 4) in respiratory and systemic compartments after pneumococcal infection. These results show that modulation of CD4+ T lymphocytes induced by L. rhamnosus CRL1505 has an important role in the beneficial effect induced by this strain on the recovery of malnourished mice. These data also indicate that nasally administered L. rhamnosus CRL1505 may represent a non-invasive alternative to modulate and improve the T cell-mediated immunity against respiratory pathogens in immunocompromised malnourished hosts.

Abstract
To gain further insights on the wedge sole (Dicologoglossa cuneata Moreau, 1881) physiology and behavior, we evaluated its daily feeding and locomotor activity rhythms and compared three different feeding strategies: self-feeding (SF), diurnal feeding schedule (DS) and nocturnal feeding schedule (NS). 450 fish divided into three groups (three replicates each), were kept during 65days. SF had free access to self-feeders whereas DS and NS were fed four times a day. Physiological stress parameters as plasma cortisol, glucose, lactate, proteins and triglycerides were determined. Under the SF setting, the 91% of feeding demands occurred during the dark phase. Furthermore, locomotor activity was also higher during the scotophase (64% of the total activity). Significantly higher values for specific growth rate (SGR) and feed efficiency rate (FER) were observed in NS (0.49 and 0.48%day-1, respectively); whereas SF consumed much less food than the rest and presented a high mortality rate (46%). Plasma cortisol levels were dramatically increased in SF and DS compared to NS (21.8±6.1, 65.8±30.3 and 0.3±0.1ngmL-1, respectively). In summary, the wedge sole appears as a species with nocturnal locomotor and feeding behaviors and NS as the most appropriate feeding strategy. These new findings appear as key information for both the preservation of natural stocks of this species and its rearing.

Abstract
The analysis by atom probe tomography (APT) of InAlAsSb layers with applications in triple junction solar cells (TJSCs) has shown the existence of In- and Sb-rich regions in the material. The composition variation found is not evident from the direct observation of the 3D atomic distribution and because of this a statistical analysis has been required. From previous analysis of these samples, it is shown that the small compositional fluctuations determined have a strong effect on the optical properties of the material and ultimately on the performance of TJSCs.
