Purification of Translating Ribosomes and Associated mRNAs from Soybean (Glycine max)
Authors: Castro‐Guerrero Norma A. , Cui Yaya , Mendoza‐Cozatl David G. 
Published: April 2016

AbstractCell identity and function are largely determined by specific gene expression patterns and ultimately by the proteome. Current high‐throughput sequencing technologies offer the possibility of quantifying gene expression at high resolution, with minimum input and without the constraints of array‐based systems, such as the need for specific probes. In addition, techniques are now available to capture genes that are actively being translated. These techniques use either density gradients or epitope‐based immunoprecipitation to purify translating ribosomes and associated mRNAs (i.e., translatomes). More recently, the combination of tissue‐specific promoters driving epitope‐tagged ribosomes with high‐throughput sequencing has allowed the identification of genes and networks unique to specific cell types. Translatome analyses have the potential to unravel genetic programs and cellular responses to environmental stresses at cell‐specific resolution. This unit describes steps for the use of epitope‐based immunoprecipitation to purify translating ribosomes from soybean and the recovery of mRNA for downstream applications such as gene expression analysis. © 2016 by John Wiley & Sons, Inc.

AbstractBackgroundGhrelin is a peptide hormone with pleiotropic effects. It stimulates cell proliferation and inhibits apoptosis‐mediated cell death. It prevents diabetes mellitus in several models of chemical, surgical and biological toxic insults to pancreas in both in vivo and in vitro models and promotes glucose‐stimulated insulin secretion under cytotoxic conditions. It has not yet been tested in vivo in an autoimmune model of diabetes with a persistent insult to the β‐cell. Given the immunomodulating effects of ghrelin and its trophic effects on β‐cells, we hypothesized that ghrelin treatment during the early stages of insulitis would delay diabetes onset.MethodsBioBreeding/Worcester male rats received ghrelin (10 ng/kg/day) before insulitis development. Glucose metabolism was characterized by glucose and insulin tolerance tests. β‐cell mass, islet area, islet number, β‐cell clusters, proliferation and apoptosis and degree of insulitis were analysed by histomorphometry. A Kaplan–Meier survival curve was plotted and analysed applying the log‐rank (Mantel–Cox) test.ResultsGhrelin treatment significantly reduced the probability of developing diabetes in our model (p < 0.0001). It decreased islet infiltration and partially prevented β‐cell mass loss, enabling the maintenance of β‐cell neogenesis and proliferation rates. Furthermore, ghrelin treatment did not induce any metabolic perturbations.ConclusionsThese findings support the hypothesis that ghrelin delays the development of autoimmune diabetes by attenuating insulitis and supporting β‐cell mass.General SignificanceGhrelin promotes β‐cell viability and function through diverse mechanisms that may have significant implications for diabetes prevention, therapy and also transplant success of both islets and complete pancreas.

AbstractAimsOur aim is to explore the associations between mitochondrial DNA (mtDNA) content and basal plasma glucose, plasma glucose after oral glucose administration and oxidative stress in a Chinese population with different levels of glucose tolerance. We also aimed to investigate the effect of mtDNA content on basal and oral glucose‐stimulated insulin secretion.MethodsFive hundred and fifty‐six Chinese subjects underwent a 75‐g, 2‐h oral glucose tolerance test. Subjects with diabetes (n = 159), pre‐diabetes (n = 197) and normal glucose tolerance (n = 200) were screened. Blood lipid profile was assessed, and levels of the oxidative stress indicators superoxide dismutase, glutathione reductase (GR) and 8‐oxo‐2′‐deoxyguanosine (8‐oxo‐dG) were measured. Levels of HbA1c, plasma glucose, insulin and C‐peptide were also determined. Measurements were taken at 0, 30, 60 and 120 min after 75 g oral glucose tolerance test. Peripheral blood mtDNA content was assessed using a real‐time polymerase chain reaction assay. Insulin sensitivity was evaluated by homeostatic model assessment of insulin resistance and Matsuda index (ISIM). Basal insulin secretion index (HOMA‐β), early phase disposition index (DI30) and total phase disposition index (DI120) indicate insulin levels at different phases of insulin secretion.ResultsPeripheral blood mtDNA content was positively associated with DI30 and DI120 and was negatively associated with plasma glucose measured 30, 60 and 120 min after oral glucose administration. However, there was no correlation between mtDNA content and basal insulin secretion (HOMA‐β), serum lipid or oxidative stress indicators (8‐oxo‐dG, superoxide dismutase, GR). HbA1c was negatively associated with GR (r = −0.136, p = 0.001). Multiple linear regression analysis showed that reduced peripheral blood mtDNA content increased the risk of impaired glucose‐stimulated β cell function (DI30: β = 0.104, p = 0.019; DI120: β = 0.116, p = 0.009).ConclusionsDecreased peripheral blood mtDNA content was more closely associated with glucose‐stimulated insulin secretion than with basal secretion. Reduction in glucose‐stimulated insulin secretion causes postprandial hyperglycaemia. The oxidative stress was probably largely influenced by hyperglycaemia; it was probably that the decreased mt DNA content led to hyperglycaemia, which caused elevated oxidative stress. © 2016 The Authors.

AbstractIt has been proposed that in slow‐growing vertebrate populations survival generally has a greater influence on population growth than reproduction. Despite many studies cautioning against such generalizations for conservation, wildlife management for slow‐growing populations still often focuses on perturbing survival without careful evaluation as to whether those changes are likely or feasible. Here, we evaluate the relative importance of reproduction and survival for the conservation of two bottlenose dolphin (Tursiopscfaduncus) populations: a large, apparently stable population and a smaller one that is forecast to decline. We also assessed the feasibility and effectiveness of wildlife management objectives aimed at boosting either reproduction or survival. Consistent with other analytically based elasticity studies, survival had the greatest effect on population trajectories when altering vital rates by equal proportions. However, the findings of our alternative analytical approaches are in stark contrast to commonly used proportional sensitivity analyses and suggest that reproduction is considerably more important. We show thatin the stable population reproductive output is higher, and adult survival is lower;the difference in viability between the two populations is due to the difference in reproduction;reproductive rates are variable, whereas survival rates are relatively constant over time;perturbations on the basis of observed, temporal variation indicate that population dynamics are much more influenced by reproduction than by adult survival;for the apparently declining population, raising reproductive rates would be an effective and feasible tool to reverse the forecast population decline; increasing survival would be ineffective.Our findings highlight the importance of reproduction – even in slow‐growing populations – and the need to assess the effect of natural variation in vital rates on population viability. We echo others in cautioning against generalizations based on life‐history traits and recommend that population modeling for conservation should also take into account the magnitude of vital rate changes that could be attained under alternative management scenarios.

AbstractFisheries that operate at large spatial scales and with high intensity have the potential to impact highly migratory species, and it is important to characterize threats to specific breeding populations of these species. We used many‐to‐many mixed‐stock analysis (MSA) (n = 408) and microsatellite assignment testing (n = 397) to determine source populations for leatherback turtles (Dermochelys coriacea) caught as bycatch in the U.S. pelagic longline fishery from 2002 to 2012 in the western North Atlantic. Within the United States, we had bycatch samples from the majority of statistical fishing areas: Gulf of Mexico (GOM), Northeast Distant (NED), Caribbean (CAR), Florida East Coast (FEC), Mid Atlantic Bight (MAB), Northeast Coastal (NEC), South Atlantic Bight (SAB) and Sargasso (SAR). We determined the proportions of turtles from each of nine nesting stocks in the Atlantic in each of the sampled areas. These nesting stocks included Brazil, Costa Rica, Florida, Trinidad, French Guiana, St. Croix, Ghana, Gabon, and South Africa. The MSA revealed that the NED had a lower relative proportion of turtles from Costa Rica than other areas and that the GOM had the highest relative proportion of turtles from Costa Rica. No turtles were assigned to the African rookeries, lending further evidence that turtles from that region forage elsewhere and therefore may not be affected by western North Atlantic fisheries. This work contributes to the ongoing assessment of threats to leatherback turtles in the Regional Management Unit (RMU) of the western North Atlantic, and draws attention to the disproportionate number of turtles from Costa Rica being caught in the Gulf of Mexico; Costa Rica is one of the only populations in the northern Atlantic that is not experiencing significant increases in nest numbers. This approach should be useful in determining population‐specific threats to other highly migratory protected species that may depend on segregated foraging areas either within or among species.
Modeling lake trophic state: a random forest approach
Authors: Hollister Jeffrey W. , Milstead W. Bryan , Kreakie Betty J. 
Published: April 2016

AbstractProductivity of lentic ecosystems is well studied, and it is widely accepted that as nutrient inputs increase, productivity increases and lakes transition from lower trophic state (e.g., oligotrophic) to higher trophic states (e.g., eutrophic). These broad trophic state classifications are good predictors of ecosystem condition, services (e.g., recreation and esthetics), and disservices (e.g., harmful algal blooms). While the relationship between nutrients and trophic state provides reliable predictions, it requires in situ water quality data to parameterize the model. This limits the application of these models to lakes with existing and, more importantly, available water quality data. To address this, we take advantage of the availability of a large national lakes water quality database (i.e., the National Lakes Assessment), land‐use/land‐cover data, lake morphometry data, and other universally available data, and we apply data‐mining approaches to predict trophic state. Using these data and random forests, we first model chlorophyllaand then classify the resultant predictions into trophic states. The full model estimates chlorophyllawith both in situ and universally available data. The mean‐squared error and adjustedR2of this model was 0.09 and 0.8, respectively. The second model uses universally availableGISdata only. The mean‐squared error was 0.22, and the adjustedR2was 0.48. The Kappa coefficients of the trophic state classifications derived from the chlorophyllapredictions were 0.57 for the full model and 0.29 for the “GIS‐only” model. Random forests extend the usefulness of the class predictions by providing prediction probabilities for each lake. This allows us to make trophic state predictions and also indicate the level of uncertainty around those predictions. For the full model, these predicted class probabilities ranged from 0.42 to 1. For theGIS‐only model, they ranged from 0.33 to 0.96. It is our conclusion that in situ data are required for better predictions, yetGISand universally available data provide trophic state predictions, with estimated uncertainty, that still have the potential for a broad array of applications.

NH4Cl selective leaching of basic oxygen furnace slag: Optimization study using response surface methodology
Authors: Sun Yong , Zhang Jing Ping , Zhang Lian 
Published: April 2016

The basic oxygen furnace slag (SL) was selectively leached by NH4Cl. Response surface methodology and the central composite design (CCD) were employed in determining the optimal condition. The process parameters such as leaching duration, NH4Cl concentration, liquid solid ratio (LSR), and leaching temperature were chosen as independent variables in CCD. The quadratic model was developed for process optimization and statistical experimental designs. It is found that the leaching duration, NH4Cl concentration and liquid solid ratio are significant to the extraction of Ca2+ and Mg2+. The optimal conditions with setting maximum extraction of calcium and magnesium cations from SL are as following: 68 min (X1), 1.8 mol/L NH4Cl (X2), LSR 12 mL/g (X3), 53°C (X4), with the predicted Ca2+ and Mg2+ concentration reaching 13.3 and 3.2 g/L, respectively. The proposed simplified leaching mechanism indicates a two‐stage leaching. The prone leachable MgFe2O4 and Ca2Fe2O5 are extracted in the fast stage, while the extraction of CaO occurs throughout slow stage. © 2016 American Institute of Chemical Engineers Environ Prog, 35: 1387–1394, 2016
Effects on Growth and Yield of Eggplant (Solanum Melongema l.) Under Placement of Drip Laterals and Using Municipal Wastewater
Authors: Tripathi Vinod Kumar , Rajput T.B.S. , Patel Neelam , Kumar Pradeep 
Published: April 2016

AbstractThis study was conducted to utilize municipal wastewater through surface and subsurface (15 and 30 cm) drip systems. Wastewater was treated though media type, disk type and combined media and disk type filters. The field experiment was conducted for two years with wastewater and groundwater. Root length density (RLD), leaf area index (LAI), and fruit yield with dry matter was recorded. LAI was lower under subsurface drip during the initial 55 days after transplantation, but in later stages it was significantly higher in comparison to surface drip. Highest RLD of 3.6 cm cm–3 was recorded under subsurface drip at 30 cm depth. RLD and LAI were related with a correlation coefficient value of 0.69. Highest dry matter content (8.75%) was recorded under surface drip but highest fruit yield was recorded under subsurface placement of drip at 15 cm depth. Subsurface drip at 15 and 30 cm depths resulted in 12.4 and 8.5% higher yields respectively, in comparison with surface drip. Utilization of wastewater through a drip irrigation system has given 6.2% increase in eggplant fruit yield in comparison to groundwater irrigation, with savings of 47, 18 and 40% of N, P2O5 and K2O nutrients respectively. The findings of the present study elucidate the potentials and constraints of wastewater utilization through a subsurface drip system. Copyright © 2016 John Wiley & Sons, Ltd.
