BIOACTIVE COMPOUNDS AND ANTIOXIDANT POTENTIAL OF SOY PRODUCTS Compostos bioativos e potencial antioxidante em derivados de soja

The aim of this work was to evaluated the amounts of bioactive compounds in soybean and derived products and the antioxidant activity (AA) assessed by the methods of ABTSÂ·+, DPPHÂ·, FRAP and peroxidation of linoleic acid (PLA). The micronized soy protein (MSP), defatted soy fl our (DSF) and textured soy protein (TSP) had a higher content of phenolic compounds and higher antioxidant activity (AA), than the other products. MSP and tofus had the highest content of fl avonoids and phytic acid (PA), respectively. The AA correlated with total phenolics and fl avonoids, but the PA can act synergistically chelating the pro oxidants ions iron and copper. The highest concentration of copper was in soy protein isolate, and of iron in an ingredient of soy fi ber and soy germ. Many compounds present in soy products contribute for the AA, but the concentration and potential will depend on fi nal preparation of the grain or ingredients before consumption.
Genetic variances for liveweight and fleece traits in Merino, Dohne Merino and South African Meat Merino sheep

(Co)variance estimates for weaning weight, yearling liveweight, clean fleece weight and fibre diameter at yearling age were obtained for Merino, Dohne Merino and South African Meat Merino flocks maintained on the same property. Direct additive genetic variances for weaning weight [expressed as a ratio of the total phenotypic variance (h2, direct heritability)] were estimated at 0.15 for Merinos, 0.21 for Dohne Merinos and 0.32 for South African Meat Merinos. Corresponding maternal variance ratios (m2, including direct maternal variance and permanent environmental maternal variance) were estimated at 0.15, 0.30 and 0.24, respectively. The correlation between direct and maternal variance ratios was high and negative in Dohne Merinos and South African Meat Merinos (–0.72 and –0.53, respectively). Direct heritability estimates for yearling liveweight were 0.30 for Merinos, 0.33 for Dohne Merinos and 0.45 for South African Meat Merinos. Corresponding maternal variance ratios were only significant in the latter 2 breeds, amounting to 0.13 in Dohne Merinos and 0.12 in South African Meat Merinos. For yearling clean fleece weight, h2 and m2 were estimated at 0.28 and 0.12, respectively, for both Merinos and Dohne Merinos. In the case of South African Meat Merinos, only the h2 estimate was significant, at 0.68. Maternal variance ratios for yearling fibre diameter were not significant in any of the breeds, while h2 ranged from 0.58 in Merinos to 0.75 in South African Meat Merinos. Selection progress for yearling traits seems likely in all breeds, depending on the breeding objectives being strived for.
Chronic mixture toxicity study of Clophen A60 and diethyl phthalate in male rats

Chemical mixtures are an important area of research as individuals are exposed to low doses of persistent chemical agents known as environmental pollutants throughout their life time. Polychlorinated biphenyls (PCBs) and diethyl phthalate (DEP) are ubiquitous environmental pollutants that could be present in the same environmental compartment; hence organisms may get simultaneously exposed to both. Therefore, a study was undertaken to see whether PCB and DEP together show interactive chronic mixture toxicity in male Wistar rats. Healthy male Wistar rats weighing 70–100 g were randomly assigned to four groups of six each. Control rats were fed on normal diet and water ad libitum. Oil control rats were maintained on a normal diet mixed with corn oil. Rats were given Clophen A60 (PCB) and DEP dissolved individually in corn oil mixed with the diet at 50 mg kg−1 of the diet/day, as well as a mixture in corn oil mixed with the diet both at 50 mg kg−1 of the diet/day. After 150 days of treatment animals were sacrificed and enzymes and other biochemical parameters in the serum and liver were assessed. Liver weight to body weight ratio showed a significant increase in Clophen A60 and in Clophen A60 + DEP treated rats. In the DEP, Clophen A60 and Clophen A60 + DEP treated groups there was significant increase in liver and serum alanine aminotransferase (ALT) and acid phosphatase (ACP) activity. Aspartate aminotransferase (AST) was significantly increased in the liver and serum of DEP treated rats only. Cholesterol levels were significantly increased only in the serum and the liver of DEP treated rats. Triglyceride levels were significantly increased in the serum of treated rats and only in the liver of Clophen A60 and Clophen A60 + DEP treated rats. Liver glycogen levels were significantly increased in DEP and Clophen A60 + DEP treated rats. In all treated animals, there was a significant decrease in liver glutathione reductase (GR). Histology of liver showed severe vacuolations, fatty degeneration and loss of hepatic architecture in Clophen A60 and Clophen A60 + DEP treated rats, whereas in DEP treated rats only loss of hepatic architecture and granular deposits in the hepatocytes was predominant with mild vacuolations of centrilobular and periportal area. It is evident from this study of mixture toxicity of Clophen A60 and DEP that there is no significantly enhanced toxicity due to the interaction of these two compounds. On the other hand, to some extent there is alleviation in toxicity as evidenced by enzyme ACP and AST levels in the liver. The hepatocellular damage and biliary congestion caused by these two compounds, which can be confirmed by significantly increased liver weights and elevated serum and liver enzyme levels as well as histology, was almost the same between individual and mixture treated group.
The Development of Context-Sensitive Attention Across Cultures: The Impact of Stimulus Familiarity

Across cultures, there are marked differences in visual attention that gradually develop between 4 and 6 years of age. According to the social orientation hypothesis, people in interdependent cultures should show more pronounced context sensitivity than people in independent cultures. However, according to the differential familiarity hypothesis, the focus on the salient object should also depend on the familiarity of the stimulus; people will focus more on the focal object (i.e., less context sensitivity), if it is a less familiar stimulus. To examine the differences in visual attention between interdependent and independent cultures while taking into account stimulus familiarity, this study used an eye-tracking paradigm to assess visual attention of participants between 4 and 20 years who came from urban middle-class families from Germany (n = 53; independent culture) or from Nso families in a rural area in Cameroon (n = 50; interdependent culture). Each participant saw four sets of stimuli, which varied in terms of their familiarity: (1) standard stimuli, (2) non-semantic stimuli, both more familiar to participants from Germany, (3) culture-specific matched stimuli, and (4) simple stimuli, similarly familiar to the individuals of both cultures. Overall, the findings show that mean differences in visual attention between cultures were highly contingent on the stimuli sets: In support of the social orientation hypothesis, German participants showed a higher object focus for the culture-specific matched stimuli, while there were no cultural differences for the simple set. In support of the differential familiarity hypothesis, the Cameroonian participants showed a higher object focus for the less familiar sets, namely the standard and non-semantic sets. Furthermore, context sensitivity correlated across all the sets. In sum, these findings suggest that the familiarity of a stimulus strongly affects individuals’ visual attention, meaning that stimulus familiarity needs to be considered when investigating culture-specific differences in attentional styles.
Effect of Water Stress on the Yield of Cowpea (Vigna unguiculata L. Walp.) Genotypes in the Delmarva Region of the United States

Drought is an important yield-reducing factor for corn and soya bean which are the two major crops in the Delaware, Maryland and Virginia (Delmarva) region of the United States. Cowpea (Vigna unguiculata L. Walp.) is primarily grown in drier regions of the world where it is one of the most drought-resistant food legumes. Field experiments were conducted in which 10 genetically diverse cowpea genotypes were evaluated for adaptability to the Delmarva area. The cowpea genotypes were grown in rain-out shelters under non-water-stressed and water-stressed conditions. The results showed that under non-water-stressed conditions cowpea genotypes California Blackeye 5, Champion and Mississippi Silver gave higher seed yields, while genotypes White Acre, Six Week Browneye and Texas Cream 8 provided lower seed yields. Genotypes California Blackeye 5 and Champion gave comparatively better seed yields under water-stressed conditions. California Blackeye 5 was the highest seed-yielding genotype under both water-stressed and non-water-stressed conditions. The highest biological yield under non-water-stressed conditions was given by genotypes Two Crop Brown, White Acre and Elite, whereas under the water-stressed condition genotypes Texas Cream 8, California Blackeye 5, and Mississippi Silver gave higher biological yield. Genotypes Quickpick Pinkeye and Elite were identified as early maturing genotypes. The harvest index (HI) varied significantly among genotypes, with Texas Cream 8 having the lowest HI. Cowpea genotypes which gave higher seed yield under water-stressed conditions could play an important role in sustaining crop production in the Delmarva region.
Changes in an Invaded Florida ant (Hymenoptera: Formicidae) Community Over 25 Years

Abstract Exotic invasive species are one of the most widespread and common agents of change in ecosystems worldwide. Here, we are focused on community-level changes associated with the appearance and persistence of exotic species in an ecosystem over more than 2 decades. We combined datasets of Florida's ant (Hymenoptera: Formicidae) community from Wekiwa Springs State Park, Florida, USA, spanning 25 yr, which included 3 sampling events in several distinct upland ecosystems. Species accumulation curves, non-parametric species estimators, community similarity indices, and ratios of exotic to native ants were used to assess sampling effort, including patterns of diversity, and changes in community composition. Our data showed that the ant community of Wekiwa Springs has at least 4 exotic species present in all of the ecosystems sampled within the park. These upland ecosystems are accumulating exotics slowly and, with one exception, there is no clear signal that the exotic species are displacing native species. The likely exception is the invasive fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), causing local extinction of the native fire ant Solenopsis geminata (Fabricius) (Hymenoptera: Formicidae). Continued long-term monitoring efforts are necessary to understand how these exotics may impact native communities in the future.
Asymmetric hybridization between two species of sunfishes (Lepomis: Centrarchidae)

Many of the sunfishes (Centrarchidae) hybridize in natural systems, yet little is known about the interactions among hybridizing individuals in nature. We used allozyme electrophoresis to identify interspecific hybrids between bluegill (Lepomis macrochirus) and pumpkinseed (L. gibbosus) in Lake Opinicon, Ontario, and restriction fragment length polymorphism analysis of mitochondrial DNA (mtDNA) to identify the maternal parentage of those individuals. All 44 individuals collected and identified electrophoreti‐cally as F1 hybrids had a pumpkinseed mtDNA haplotype, indicating that hybridization between these species in Lake Opinicon is asymmetrical; F1 hybrids result only from matings between female pumpkinseed and male bluegill.
Requirements for the Assembly and Release of Newcastle Disease Virus-Like Particles

Paramyxoviruses, such as Newcastle disease virus (NDV), assemble in and bud from plasma membranes of infected cells. To explore the role of each of the NDV structural proteins in virion assembly and release, virus-like particles (VLPs) released from avian cells expressing all possible combinations of the nucleoprotein (NP), membrane or matrix protein (M), an uncleaved fusion protein (F-K115Q), and hemagglutinin-neura-minidase (HN) protein were characterized for densities, protein content, and efﬁciencies of release. Coexpres- sion of all four proteins resulted in the release of VLPs with densities and efﬁciencies of release (1.18 to 1.16 g/cm 3 and 83.8% (cid:1) 1.1%, respectively) similar to those of authentic virions. Expression of M protein alone, but not NP, F-K115Q, or HN protein individually, resulted in efﬁcient VLP release, and expression of all different combinations of proteins in the absence of M protein did not result in particle release. Expression of any combination of proteins that included M protein yielded VLPs, although with different densities and efﬁciencies of release. To address the roles of NP, F, and HN proteins in VLP assembly, the interactions of proteins in VLPs formed with different combinations of viral proteins were characterized by coimmunoprecipitation. The colocalization of M protein with cell surface F and HN proteins in cells expressing all combinations of viral proteins was characterized. Taken together, the results show that M protein is necessary and sufﬁcient for NDV budding. Furthermore, they suggest that M-HN and M-NP interactions are responsible for incorporation of HN and NP proteins into VLPs and that F protein is incorporated indirectly due to interactions with NP and HN protein.
Preferences by Rhagoletis indifferens (Diptera, Tephritidae) for rectangles of various yellow colours and fluorescence

Sticky rectangle traps of various yellow colours and fluorescence made of cardboard were field tested against western cherry fruit fly, Rhagoletis indifferens Curran, in paired trap preference experiments in Washington state. In a first experiment that involved comparisons of Alpha Scents (proprietary paint), Fluorescent Yellow (aerosol paint), Saffron Thread and Neon Light (semi‐gloss enamel paints) traps at two sites, the best performing trap was the Saffron Thread trap. In a second experiment comparing Citrus Splash (semi‐gloss enamel paint) with Alpha Scents and with Macaw and Lemon Zest (both semi‐gloss enamel paints) traps at a third site, the Citrus Splash trap outperformed the Alpha Scents trap. The Citrus Splash trap did not differ statistically from Saffron Thread and Lemon Zest traps, even though it caught 51% more flies than the Lemon Zest trap. The Alpha Scents trap caught significantly more non‐target Diptera than Fluorescent Yellow, Neon Light and Citrus Splash traps at two of three trap sites where non‐target Diptera populations were relatively high and overall it appeared less selective than the Citrus Splash trap. Results suggest that sticky rectangle traps painted semi‐gloss enamel Saffron Thread or Citrus Splash with low fluorescence could be highly useful for detecting R. indifferens.
Graft IL-33 regulates infiltrating macrophages to protect against chronic rejection.

Alarmins, sequestered self-molecules containing damage-associated molecular patterns, are released during tissue injury to drive innate immune cell pro-inflammatory responses. Whether endogenous negative regulators controlling early immune responses are also released at the site of injury is poorly understood. Herein, we establish that the stromal cell-derived alarmin interleukin-33 (IL-33) is a local factor that directly restricts the pro-inflammatory capacity of graft infiltrating macrophages early after transplantation. By assessing heart transplant recipient samples and using a mouse heart transplant model, we establish that IL-33 is upregulated in allografts to limit chronic rejection. Mouse cardiac transplants lacking IL-33 displayed dramatically accelerated vascular occlusion and subsequent fibrosis, which was not due to altered systemic immune responses. Instead, a lack of graft IL-33 caused local augmentation of pro-inflammatory iNOS+ macrophages that accelerated graft loss. IL-33 facilitated a metabolic program in macrophages associated with reparative and regulatory functions, and local delivery of IL-33 prevented the chronic rejection of IL-33-deficient cardiac transplants. Therefore, IL-33 represents a novel regulatory alarmin in transplantation that limits chronic rejection by restraining the local activation of pro-inflammatory macrophages. The local delivery of IL-33 in extracellular matrix based-based materials may be a promising biologic for chronic rejection prophylaxis.
Monitoring of Surface Temperature on Parco delle Biancane (Italian Geothermal Area) Using Optical Satellite Data, UAV and Field Campaigns

The purpose of this study is to analyze the surface temperature and the distribution of thermal signatures on Tuscany’s geothermal districts using data obtained through three separate surveys via satellite and an unmanned aerial vehicle (UAV). The analysis considers the highest available spatial resolution ranging from hundreds of meters per pixel of the satellite thermal images and the tenths/hundreds of centimeters per pixel of the thermal images acquired by the UAV. The surface temperature maps obtained by satellite data acquired at suitable spatial resolution and the thermal measurements obtained by the thermal camera installed on the UAV were orthorectified and geocoded. This allowed, for example, following the evolution of thermal anomalies, which may represent a modification of the current state of the geothermal field and a possible hazard for both the population and industrial assets. Here, we show the results obtained in three field campaigns during which the simultaneous acquisition of Landsat 8 satellite and UAV (FlyBit octocopter, IDS, Rome, Italy) thermal data were analyzed. By removing the atmosphere contribution from Landsat 8 data, we have produced three surface temperature maps that are compared with the ground field measurements and the surface temperature maps elaborated by FLIR VUE PRO-R on the UAV.
TNF reduces LIF endocytosis despite increasing NFκB‐mediated gp130 expression

To examine how the proinflammatory cytokine tumor necrosis factor α (TNF) modulates the response of cerebral microvessels to other cytokines, we used rat cerebral microvessel endothelial RBE4 cells to simulate the in vitro blood‐brain barrier (BBB). The gp130 receptor, which is shared by the interleukin (IL)‐6 family of cytokines, showed specific upregulation by TNF. TNF treatment (5 ng/ml for 30 min to 24 h) increased gp130 at both the levels of transcription and protein expression. The stability of gp130 protein was mediated by NFκB activity, as the inhibitors quinazoline and MG132 not only blocked the increase induced by 6 h of TNF treatment, but also reduced its basal level of expression. By contrast, the lysosomal inhibitor chloroquine and the extracellular regulated kinase inhibitor U0126 showed no effect. Despite the increase of gp130, TNF caused a significant reduction in the cell binding and endocytosis of leukemia inhibitory factor (LIF), another proinflammatory cytokine that binds to the gp130 co‐receptor and its unique gp190 receptor. This is consistent with our previous findings that TNF reduces gp190 expression and Stat3 activation. Thus, TNF stimulation results in decreased responsiveness of RBE4 cells to LIF, indicating complex regulatory interactions of cytokines at the BBB. J. Cell.

A study of the association between cognitive abilities and dietary intake in young women

Background: Cognitive abilities comprise activities that relate to receiving and responding to information from the environment, internal processing, making complex decisions, and then responding to this in the context of behavior. Aim: The current study investigated the association between dietary intake and seven aspects of cognitive abilities among healthy young women. Methods: The study was carried out among 182 women aged 18–25 years. A valid and reliable food frequency questionnaire containing 65 food items was used to estimate dietary intake. Neuropsychological function and cognitive abilities of participants were determined using standard questionnaires. Results: Significant differences were found in depression, anxiety, stress, physical, and mental health-related quality of life as well as daytime sleepiness for the participants in different quartiles of cognitive abilities score (p<0.05). Participants in the fourth quartile of cognitive abilities score consumed significantly higher energy, carbohydrate, protein, calcium, iron, zinc, vitamin A, thiamin, and riboflavin compared to those in the lowest quartile (p<0.05). There were strong correlations between total cognitive abilities score and dietary sodium, calcium, phosphorus, and thiamin (p<0.05). Using stepwise multiple linear regression analysis, iron and thiamin were statistically significant factors for the prediction of cognitive abilities. Conclusions: These findings demonstrate that neurocognitive function is related to dietary macro and micronutrients including energy, carbohydrate, protein, calcium, iron, zinc, vitamin A, thiamin, and riboflavin on cognitive performance among young women without memory deficit.
Genetic background of behavioural and plasma cortisol response to repeated short-term separation and tethering of beef calves

Summary In this study the response to short-term separation and tethering were tested individually 5, 19 and 33 days after birth in five progeny groups of German Angus and German Simmental and genetic parameters were estimated. Heritabilities (±SE) for different behavioural traits varied between 0.02 (±0.05) and 0.33 (±0.24) for German Angus and 0.0 and 0.29 (±0.12) for German Simmental. German Simmental and female calves moved significantly more on days 19 and 33 and were scored for fearful than German Angus and male calves. They also showed higher plasma cortisol levels at all tested ages. Behavioural and cortisol responses decreased with every test, indicating that the animals got used to the gentle handling procedure. Zusammenfassung Untersuchungen zum genetischen Hintergrund des Verhaltens sowie der Plasmakortisolkonzentrationen von Fleischrinderkalbern nach wiederholter kurzer Separierung und Fixierung Funf Nachkommengruppen der Mutterkuhrassen Dt. Angus und Dt. Fleckvieh wurden im Alter von 5, 19 und 33 Tagen nach der Geburt einem Test zur Ermittlung des Temperamentes unterzogen. Die Heritabilitaten der Parameter lagen fur Dt. Angus zwischen 0.02 (±0.05) und 0.33 (±0.24) und fur Dt. Fleckvieh zwischen 0.0 und 0.29 (±0.12). Tiere der Rasse Dt. Fleckvieh sowie weibliche Kalber bewegten sich wahrend der Tests haufiger und erhielten im Durchschnitt niedrigere Verhaltensnoten. Diese Tiere hatten auch hohere Plasmakortisolwerte als Kalber der Rasse Dt. Angus sowie mannlichen Geschlechts. Die Bewegungszeiten sowie Plasmakortisolwerte sanken bei beiden Rassen mit jeder Wiederholung, was auf eine Gewohnung an die nicht schmerzhafte Prozedur hindeutet.
