Social approach in preschool children with Williams syndrome: The role of the face.

Background Indiscriminate social approach behaviour is a salient aspect of the Williams syndrome (WS) behavioural phenotype. The present study examines approach behaviour in preschoolers with WS and evaluates the role of the face in WS social approach behaviour. Method Ten preschoolers with WS (aged 3-6 years) and two groups of typically developing children, matched to the WS group on chronological or mental age, participated in an observed play session. The play session incorporated social and non-social components including two components that assessed approach behaviour towards strangers, one in which the stranger’s face could be seen and one in which the stranger’s face was covered. Results In response to the non-social aspects of the play session, the WS group behaved similarly to both control groups. In contrast, the preschoolers with WS were significantly more willing than either control group to engage with a stranger, even when the stranger’s face could not be seen. Conclusion The findings challenge the hypothesis that an unusual attraction to the face directly motivates social approach behaviour in individuals with WS

Perfil nutricional y antioxidante post-cosecha de Beta vulgaris L. cultivada en microhuerto sin suelo de baja emisión con nutrientes orgánicos e inorgánicos

Beetroot was grown in an open soilless cultivation system with nutrition supplied by organic and inorganic sources. This low emission system was tested for microgardening high quality red beets with high water use efficiency and less pollutant emission in the environs. For this purpose, a pot experiment was planned according to completely randomized design. For inorganically grown red beets, peat moss was combined with 150, 200 and 250 ppm NH4NO3, whereas for organic red beets, peat moss was amended with compost having nitrogen equivalent to the mentioned NH4NO3 concentrations. Rosette and roots were analysed for fresh and dry biomass. Nitrate content, total soluble solids, titratable acidity, ripening index, ascorbic acid, betacyanins, flavonols and antioxidant capacity were assessed as beetroot quality attributes. Combination of peat moss with NH4NO3 showed comparatively lower fresh plant biomass, fresh and dry biomasses of rosette and root, and root to rosette ratio. However, enhanced antioxidant activity and bioaccumulation of ascorbic acid, total soluble solids, betacyanins, flavonols and reduced titratable acids, resulting in higher ripening index and good quality were observed in peat moss combined NH4NO3 treated beetroots. Overall, combination of peat moss with NH4NO3 led to higher nutritional and antioxidant quality of red beet plants.La remolacha se cultivó en un sistema de cultivo abierto sin suelo con nutrición suministrada por fuentes orgánicas e inorgánicas. Este sistema de baja emisión fue probado para la microhorticultura de remolachas rojas de alta calidad con una eficiencia alta de uso de agua y menor emisión de contaminantes a los alrededores. Con esta finalidad se planificó un experimento en macetas de acuerdo con un diseño completamente al azar. Para las remolachas rojas cultivadas inorgánicamente se combinó musgo de turbera con 150, 200 y 250 ppm de NH4NO3, mientras que para las orgánicas se adecuó el musgo de turbera con compost con un contenido de nitrógeno equivalente a las concentraciones de NH4NO3 mencionadas. Se analizó el contenido de biomasa fresca y seca de la roseta y de la raíz. El contenido de nitratos, los sólidos solubles totales, la acidez titulable, el índice de maduración, el ácido ascórbico, las betacianinas, los flavonoles y la capacidad antioxidante se evaluaron como atributos de calidad de la remolacha. La combinación de musgo de turbera con NH4NO3 mostró valores comparativamente más bajos de biomasa fresca de planta, de biomasa fresca y seca de roseta y raíz, y de relación raíz‑roseta. Sin embargo, también se observaron valores más altos de actividad antioxidante y bioacumulación de ácido ascórbico, sólidos solubles totales, betacianinas, flavonoles y menos ácidos titulables, lo que resultó en un mayor índice de maduración y buena calidad. En general, la combinación de musgo de turbera con NH4NO3 condujo a una mayor calidad nutricional y antioxidante de las plantas de remolacha roja.Fil: Ejaz, Shaghef.Fil: Jezik, Karoline Maria.Fil: Anjum, Muhammad Akbar.Fil: Gosch, Christian.Fil: Halbwirth, Heidrun.Fil: Stich, Karl

Possible solutions for replant problems caused by soil-borne pathogens in organic strawberry production

Soil-borne pathogens, above all Verticillium sp. cause plant losses and yield decreases in many Austrian strawberry fields, also in organic farming systems; in a research project possibilities to resolve this problem were examined. In a field trial, which was started 1998, organically managed and differently fertilized plots (green compost, manure, hornchips) were compared to an unfertilised control plot and to two mineral fertilized and conventionally treated plots; the differences in field characteristics of strawberries in 2004 and 2005 were low, but differences in storage and biochemical characteristics could be seen in 2005. Some new cultivars tested as alternative to the very sensitive 'Elsanta' planted in 2005 on several farms showed a higher tolerance to diseases and good yield and fruit quality characteristics. Brassica sp. planted as an intercrop before strawberries reduced the amount of microsclerotia of Verticillium dahliae in highly infested soils, nevertheless the system has to be optimised and adapted to our climatic and husbandry conditions in further trials

Patterns and predictors of fast food consumption with acute myocardial infarction

Computational Infrastructure & Informatics Poster SessionBackground: Fast food is affordable and convenient, yet high in calories, saturated fat and sodium. The prevalence of fast food intake at the time of acute myocardial infarction (AMI) and patterns of fast food intake in recovery are unknown. Moreover, the association between dietary counseling at hospital discharge and fast food intake after MI has not been described. Methods: We assessed baseline, 1 and 6-month fast food intake in 2494 patients in TRIUMPH, a 26-center, prospective registry of AMI patients. Fast food intake was divided into frequent (≥ weekly) vs. infrequent (< weekly) consumption. Multivariable regression was used to identify predictors of frequent fast food intake at 6-months, adjusted for baseline fast food consumption, sociodemographics and clinical factors. Results: Frequent fast food intake was common at the time of AMI (36%), but decreased substantially after AMI to 17% at 1-month and 20% at 6-months (p-value <0.0001). Patient characteristics independently associated with frequent fast food intake at 6-months included white race, male gender, health literacy, financial difficulty, dyslipidemia and diabetes. College education, heart failure and coronary revascularization during AMI admission were inversely associated with 6-month fast food consumption. Importantly, dietary counseling at discharge was not associated with lower 6-month fast food intake. Conclusion: Fast food consumption declined substantially after AMI. Certain populations, including patients with financial difficulty and lower health literacy continued to eat fast food frequently after their event. Although several patient groups are at risk for persistent high fast food intake, current dietary counseling efforts appear ineffective at altering behavior and new counseling strategies are needed

The development of metaphorical language comprehension in typical development and in Williams syndrome

The domain of figurative language comprehension was used to probe the developmental relation between language and cognition in typically developing individuals and individuals with Williams syndrome. Extending the work of Vosniadou and Ortony, the emergence of nonliteral similarity and category knowledge was investigated in 117 typically developing children between 4 and 12 years of age, 19 typically developing adults, 15 children with Williams syndrome between 5 and 12 years of age, and 8 adults with Williams syndrome. Participants were required to complete similarity and categorization statements by selecting one of two words (e.g., either “The sun is like ___” or “The sun is the same kind of thing as ___”) with word pairs formed from items that were literally, perceptually, or functionally similar to the target word or else anomalous (e.g., moon, orange, oven, or chair, respectively). Results indicated that individuals with Williams syndrome may access different, less abstract knowledge in figurative language comparisons despite the relatively strong verbal abilities found in this disorder

Variation in practice regarding pretreatment with dual antiplatelet therapy for patients with non–ST elevation myocardial infarction

BACKGROUND: Despite guideline recommendations, a significant number of patients with non–ST elevation myocardial infarction (NSTEMI) do not receive dual antiplatelet therapy (DAPT) before angiography “pretreatment.” While there may be valid clinical reasons to not pretreat, such as concern for bleeding or multivessel disease warranting coronary artery bypass graft surgery, the degree of variability and factors associated with DAPT pretreatment are unknown. METHODS AND RESULTS: From the multicenter TRIUMPH registry, 1632 NSTEMI patients were not taking DAPT on admission and were included in the study cohort. Among the study patients, only 22% patients received DAPT pretreatment. A multivariable logistic regression model showed that race other than white or black (odds ratio [OR] 0.41, 95% CI 0.21–0.83), hemoglobin level (OR 1.18, 95% CI 1.08–1.29), patients’ bleeding risk (assessed with NCDR CathPCI Bleeding Risk Score) (OR 0.85, 95% CI 0.74–0.99), and severe left ventricular dysfunction (OR 0.3, 95% CI 0.13–0.65) were the main predictors of pretreatment with DAPT, whereas likelihood of needing coronary artery bypass graft surgery (GRACE prediction model) was not (OR 1.09, 95% CI 0.88–1.35). Median ORs were calculated to assess variability of receiving DAPT pretreatment across sites after adjustment for patient characteristics. Receiving DAPT pretreatment varied substantially across sites (range 0–100%, mean OR 3.94, P<0.0001). CONCLUSIONS: While deviating from guideline‐recommended DAPT pretreatment in patients with NSTEMI was associated with patient factors (eg, bleeding risk), marked variation was present across sites after accounting for patient‐level characteristics. This suggests that site‐level interventions are needed to improve concordance with current guidelines

Oxazole-Bridged Combretastatin A-4 Derivatives with Tethered Hydroxamic Acids: Structure-Activity Relations of New Inhibitors of HDAC and/or Tubulin Function

New inhibitors of tubulin polymerization and/or histone deacetylase (HDAC) activity were synthesized by attaching alkyl tethered hydroxamic acid appendages of varying length to oxazole-bridged combretastatin A-4 analogous caps. While their antiproliferative and microtubule disrupting effect was most pronounced for derivatives with short spacers, HDAC inhibition was strongest for those with longer spacers. These findings were further supported by computational methods such as structure-based docking experiments exploring the target interactions of the derivatives with varying linkers. For instance, compounds featuring short four-atom spacers between cap and hydroxamic acid inhibited the growth of various cancer cell lines and human endothelial hybrid cells with IC50 values in the low nanomolar range. In line with their ability to inhibit the microtubule assembly, four- and five-atom spacered hydroxamic acids caused an accumulation of 518A2 melanoma cells in G2/M phase, whereas a compound featuring a six-atom spacer and performing best in HDAC inhibition, induced a G1 arrest in these cells. All these beneficial anticancer activities together with their selectivity for cancer cells over non-malignant cells, point out the great potential of these novel pleiotropic HDAC and tubulin inhibitors as drug candidates for cancer therapy
