The acyl-CoA thioesterase I is regulated by PPARα and HNF4α via a distal response element in the promoter Published, JLR Papers in Press, May 7, 2007.

The cytosolic acyl-coenzyme A thioesterase I (Acot1) is an enzyme that hydrolyzes long-chain acyl-CoAs of C12-C20-CoA in chain length to the free fatty acid and CoA. Acot1 was shown previously to be strongly upregulated at the mRNA and protein level in rodents by fibrates. In this study, we show that Acot1 mRNA levels were increased by 90-fold in liver by treatment with Wy-14,643 and that Acot1 mRNA was also increased by 15-fold in the liver of hepatocyte nuclear factor 4α (HNF4α) knockout animals. Our study identified a direct repeat 1 (DR1) located in the Acot1 gene promoter in mouse, which binds the peroxisome proliferator-activated receptor α (PPARα) and HNF4α. Chromatin immunoprecipitation (ChIP) assay showed that the identified DR1 bound PPARα/retinoid X receptor α (RXRα) and HNF4α, whereas the binding in ChIP was abrogated in the PPARα and HNF4α knockout mouse models. Reporter gene assays showed activation of the Acot1 promoter in cells by the PPARα agonist Wy-14,643 after cotransfection with PPARα/RXRα. However, transfection with a plasmid containing HNF4α also resulted in an increase in promoter activity. Together, these data show that Acot1 is under regulation by an interplay between HNF4α and PPARα.
High Incorporation of Essential Fatty Acids by the Rotifer Brachionus plicatilis Fed on the Prymnesiophyte Alga Pavlova lutheri

The lipid and fatty acid compositions of rotifers (Brachionus plicatilis) fed on yeast or on the unicellular prymnesiophyte Pavlova lutheri, an alga commonly used in Australian hatcheries, were compared by TLC-FID, GC and GC-MS. Significantly higher relative proportions of energy-rich triacylglycerol were present in the Pavlova-fed rotifers than in the yeast-fed animals, and total lipid content reached a maximum between 12 and 24 h. High incorporation of the essential fatty acids eicosapentaenoic acid (EPA; 20: 5ω3) and docosahexaenoic acid (DHA; 22:6ω3) occurred in the Pavlova-fed rotifers. EPA and DHA content was 11.6% of total fatty acids after 3 h of feeding and reached 20 and 23% after 24 and 48 h respectively. The proportion of essential fatty acids in rotifers fed Pavlova compares very favourably with data obtained by overseas workers using a variety of microalgae and dietary supplements. On the basis of fatty acid composition alone, these results confirm the suitability of P. lutheri as a feedstock for Australian mariculture operations.
Community reorganization in the Gulf of Alaska following ocean climate regime shift

A shift in ocean climate during the late 1970s triggered a reorganization of community structure in the Gulf of Alaska ecosystem, as evidenced in changing catch composi- tion on long-term (1953-1997) small-mesh trawl surveys. Forage species such as pandalid shrimp and capelin declined because of recruitment failure and predation, and populations have not yet recovered. Total trawl catch biomass declined > 50% and remained low through the 1980s. In contrast, recruitment of high trophic-level groundfish improved during the 1980s, yielding a > 250% increase in catch biomass during the 1990s. This trophic reorganization apparently had negative effects on piscivorus sea birds and marine mammals.
Assessment of statistic and hybrid LES turbulence closures for complex free-surface flow simulation with combined grid refinement criteria

In many complex flow configurations which are now of great interest like, for instance, the onset and progression of vortical structures behind appendages and ships at high drift angles, the reliability of the numerical predictions can be questioned. First of all, it is difficult to control the numerical diffusion for the simulation over long distance of intense and localized three-dimensional structures. Furthermore, the flow in the core of a vortex is char-acterised by rotation, streamline curvature effects which are not adequately modelled by classical eddy-viscosity based turbulence models. This creates a strong source of modelling error interfering with the above-mentioned dis-cretisation error. This paper tries to provide some answers about the requirements in terms of local discretisation error and in terms of physics by analyzing computations of test cases representative of viscous hydrodynamics.
Dietary lipid source and vitamin E influence on chicken meat quality and lipid oxidation stability

Dietary Lipid Source and Vitamin E Influence on Chicken Meat Quality and Lipid Oxidation Stability. (May 2008) Carlos Narciso Gaytán, B. A. G. , Universidad Autonoma Chapingo; M. S. , Colegio de Postgraduados Chair of Advisory Committee: Dr. Marcos X. Sánchez-Plata In the poultry industry, further processed meat products have the highest share in the market, and because there is a growing demand of food products with enriched amounts of unsaturated fatty acids, the objectives of this research were to assess lipid oxidation development and quality characteristics of chicken meat as affected by dietary fat and vitamin E levels. Broilers were fed during six weeks with diets containing animal/vegetable, lard, palm kernel, soybean, conjugated linoleic acid, flaxseed, or menhaden oil. Each lipid diet was supplemented with either a control (33 or 42 mg/kg) or a supranutritional level (200-400 or 200 mg/kg) of vitamin E. Breast and thigh meat, or skin, were processed, packaged, and refrigerated as raw meat, cooked patties, or cooked sous vide meat. The results showed that the chicken meat fatty acid composition reflected those from the dietary fats. In the meat or skin there was a higher lipid oxidation susceptibility as the proportion of unsaturated fatty acids increased, shown as malonaldehyde values, particularly in the treatments with low supplemented level of vitamin E (P<0.05). The relative lipid oxidative stability of the meat decreased in
Identification of Markers Linked to Seedlessness in Citrus kinokuni hort. ex Tanaka and Its Progeny Using Bulked Segregant Analysis

Additional index words. seeded, seedless, breeding, MAS, RAPDs, Mukaku kishu Abstract. Citrus kinokuni 'Mukaku kishu' PI539530 and its progeny were studied to identify random amplified polymorphic DNA (RAPD) primers associated with seedless- ness. Ninety-one F1 ((Robinson op) · C. kinokuni) individuals showed a 1:1 segregation ratio between seedless and seeded phenotypes with seedless as a single dominant gene. Bulkedsegregantanalysiswasusedtoidentify markersassociated withtheseedlesslocus. Eighteen RAPD primers were mapped into a partial linkage group ('55.8 cM length) with four RAPD primers flanking the seedless locus: OPAI11-0.8 at 8.7 cM, OPAJ19-1.0 at 8.4 cM, OPM06r-0.85 at 4.3 cM, and OPAJ04r-0.6 at 6.4 cM. The identification of molecular markers linked to C. kinokuni Fs seedless locus constitutes an important and major tool for citrus breeding and selection.
THE SALINITY EFFECT ON MORPHOLOGY AND PIGMENTS CONTENT IN THREE PAU- LOWNIA CLONES GROWN EX VITRO

MILADINOVA, K. , K. IVANOVA, T. GEORGIEVA, M. GENEVA and Y. MARKOVSKA, 2013. The salinity effect on morphology and pigments content in three Paulownia clones grown ex vitro. Bulg. J. Agric. Sci., Supplement 2, 19: 52–56 We evaluated the effect of salt stress on growth parameters, chlorophyll a, chlorophyll b and carotenoids content in Paulownia clones (P. elongata x fortunei x elongata – T2, P. elongata x elongata – T4, P. elongata x kawakarnii – EK) grew as hydroponic culture at three levels of salinity, 50 mmol.l –1 , 100 mmol.l –1 , 200 mmol.l –1 sodium chloride (NaCl) solution. The root and stem length, as well as leaf number and total leaf area of T2 clone were reduced insignifi cantly in comparison with these of T4 and EK clones during NaCl treatment. Control of T2 clone was characterized with approximately twice higher total dry mass per plant than EK and T4 clones. The root dry mass to shoot dry mass ratios of three clones changed in a different manner with increasing salinity levels and was highest in EK clone at 200 mmol.l –1 NaCl, followed by T4 and T2. The total leaf area showed the capability of a plant in forming of photosynthetic surface and was reduced more in T4 and EK clones under salt stress. Our results suggest that T2 clone was more tolerant to salt stress than EK and T4 clones.
Machine Learning Classification Ensemble of Multitemporal Sentinel-2 Images: The Case of a Mixed Mediterranean Ecosystem

: Land cover type classiﬁcation still remains an active research topic while new sensors and methods become available. Applications such as environmental monitoring, natural resource management, and change detection require more accurate, detailed, and constantly updated land-cover type mapping. These needs are fulﬁlled by newer sensors with high spatial and spectral resolution along with modern data processing algorithms. Sentinel-2 sensor provides data with high spatial, spectral, and temporal resolution for the in classiﬁcation of highly fragmented landscape. This study applies six traditional data classiﬁers and nine ensemble methods on multitemporal Sentinel-2 image datasets for identifying land cover types in the heterogeneous Mediterranean landscape of Lesvos Island, Greece. Support vector machine, random forest, artiﬁcial neural network, decision tree, linear discriminant analysis, and k-nearest neighbor classiﬁers are applied and compared with nine ensemble classiﬁers on the basis of di ﬀ erent voting methods. kappa statistic, F1-score, and Matthews correlation coe ﬃ cient metrics were used in the assembly of the voting methods. Support vector machine outperformed the base classiﬁers with kappa of 0.91. Support vector machine also outperformed the ensemble classiﬁers in an unseen dataset. Five voting methods performed better than the rest of the classiﬁers. A diversity study based on four di ﬀ erent metrics revealed that an ensemble can be avoided if a base classiﬁer shows an identiﬁable superiority. Therefore, ensemble approaches should include a careful selection of base-classiﬁers based on a diversity analysis.
Depth‐related cell‐specific bacterial leucine incorporation rates on particles and its biogeochemical significance in the Northwest Mediterranean

A study of total and particle‐associated bacteria in the Northwest Mediterranean revealed notable relationships with depth. Cell‐specific leucine incorporation rates by total bacteria decreased significantly with depth (to 380 m), best fitting the power function log (rate) = 2.1–0.54 log (depth), r2 = 0.57, P = <0.001. In contrast, cell‐specific leucine incorporation rates by particle‐associated bacteria increased with depth as described by the power function log (rate) = 0.4 + 0.84 log (depth), r2 = 0.74, P = <0.01. We suggest that this relationship may reflect availability of usable dissolved organic matter (UDOM) and/or inorganic nutrients within the particle with increasing water depth. The latter relationship could also be interpreted in relation with time, i.e., be a consequence of the time taken for enzyme induction and solubilization of particulate organic matter (POM) to UDOM and the subsequent incorporation into bacterial protein during the sinking of the particle. These results may help to explain observations that sinking particles are rapidly decomposed between 100 and 500 m. Bacteria associated with particles in the Mediterranean contributed only 0.8–2.8% of total bacterial numbers but contributed 3–12% of total bacterial production in the upper 70 m. However, their contribution to total bacterial production in deeper waters was substantially higher (48% at 380 m). The activity of attached bacteria is, therefore, important and varies with depth, and this may help to explain the particularly low particle flux and hence the impoverished benthic environment found in the deeper waters of the Mediterranean.
Tourism-Oriented Educational Leadership in the Dominican Republic: The Key to Change

Educational leadership as a driving force in developing countries entails transforming the tourism students of today into the leaders of tomorrow by providing them with a system of values from a constructivist, competence-based perspective. The transfer of knowledge from educational settings to the tourism industry can foster innovation and enable different managerial approaches in the tertiary sector. Moreover, the impacts on third-world societies at the economic, sociocultural, and environmental levels can facilitate sustainable development. In the case of the Dominican Republic, the need to rethink the bachelor's degree in tourism has been the key to change.
A new species of the genus Tigriopus (Copepoda: Harpacticoida: Harpacticidae) from Antarctica

Abstract Tigriopus kingsejongensis, new species, is described from tidal pools near the King Sejong Station on King George Island, Antarctica. The new species is closely related to Tigriopus kerguelenensis from Kerguelen Island. Both species share several characters, including the presence of an abexopodal seta on the allobasis of the antenna in the male, the setal formula of the swimming legs, and the shape of the P5 exopod in the female. However, the new species is distinguishable from its congeners by the combined characters of a relatively well-developed abexopodal seta on the antennary allobasis, and a knob-like structure in the middle of the lateral margin of the second endopodal segment of the P2 in the male. The new species belongs to the ‘Austral islands group' within the genus. The mtCOI gene sequence is provided as a DNA barcode for the new species, and a phylogenetic tree based on the DNA sequences is also suggested.
DrMaMP: Distributed Real-time Multi-agent Mission Planning in Cluttered Environment

Solving a collision-aware multi-agent mission planning (task allocation and path finding) problem is challenging due to the requirement of real-time computational performance, scalability, and capability of handling static/dynamic obstacles and tasks in a cluttered environment. This paper proposes a distributed real-time (on the order of millisecond) algorithm DrMaMP, which partitions the entire unassigned task set into subsets via approximation and decomposes the original problem into several single-agent mission planning problems. This paper presents experiments with dynamic obstacles and tasks and conducts optimality and scalability comparisons with an existing method, where DrMaMP outperforms the existing method in both indices. Finally, this paper analyzes the computational burden of DrMaMP which is consistent with the observations from comparisons, and presents the optimality gap in small-size problems.
Oncomelania hupensis (Gastropoda: Rissooidea), Intermediate Host Of Schistosoma japonicum In China: Genetics and Molecular Phylogeny Based On Amplified Fragment Length Polymorphisms

Schistosomiasis japonica is one of the most serious parasitic diseases in China. Subspecies of the pomatiopsid snail species Oncomelania hupensis transmit the human blood fluke Schistosoma japonicum, the parasite causing the disease. In at least one study involving the subspecies Oncomelania hupensis robertsoni, there was no clear phylogenetic concordance between the mitochondrial and nuclear data, and it was strongly recommended that future studies incorporate more data from nuclear loci in order to better understand phylogeography and host-parasite coevolution (Wilke et al., 2006). In this paper, we explore genetic diversity based AFLP data involving 25 populations throughout mainland China. AFLP is a DNA fingerprinting technique that detects the polymorphism of the whole genome without prior knowledge of the nucleotide sequence, with the high degree of reproducibility and small amount of template DNA needed. Our AFLP data show that: (1) the genetic diversity within an O. hupensis population increases gradually with snail sample size, and when the sample size is more than 30 individuals, the genetic variation within one O. hupensis population trends to stabilization. (2) There is high intra-population genetic variation on the mainland of China, and these intra-population genetic variations from different areas differ significantly. (3) The considerable genetic differentiation occurs throughout China. (4) The genetic variation among populations of O. h. hupensis is higher than that of O. h. robertsoni. (5) The patterns of genetic differentiation are basically consistent with geographical distribution of snail populations. Our results are similar to the results of allozymes and COI gene sequences, excluding a snail population from Guangxi Province (Gx-1), indicating that there are three distinct subspecies in mainland China, namely O. h. hupensis, O. h. robertsoni, and O. h. tangi. However, our results do not support that the snail population from Guangxi Province belongs to O. h. hupensis.
The Mathematical Representation of Migration

If sufficiently systematic numerical observations or trappings of birds or other animals on migration are made, and the accumulating totals plotted on probability paper on a time base or abscissa, they will frequently plot to a fairly good straight line. This means that the ``distribution'' of the observations in time is approximately Gaussian, and from the plot the peak of migration and the standard deviation of the timing can be ascertained with some accuracy. This can be done, for most passage—migrant species, for both spring and fall migrations, and so the distance or interval between peaks can be ascertained also. Theoretically the distribution cannot be exactly Gaussian, since the Gaussian curve would take an infinity of time to become complete. A more suitable theoretical form of graduating curve is the cosine—power distribution, whose parameters can be ascertained from the Gaussian parameters obtained from the probability—paper plots. The cosine—power law is a well—known statistical distribution, .
Segmentation of Microscopic Images of Living Cells: A Study

In this paper, three different segmentation techniques are used, namely, region growing segmentation technique, watershed segmentation and texture segmentation, to accurately extract the shapes of membranes and nuclei from the inverted microscopic images, taken throughout the monolayer formation of BGM-70 (Baby Grevit Monkey) cell culture. This strategy is a prerequisite for an accurate quantitative analysis of cell shape and morphodynamics during organogenesis and is the basis for an integrated understanding of biological processes. The segmentation of cellular structures is achieved by first normalizing the microscopic images by performing CLAHE operation followed by de-noising by morphological opening and filling of the holes and then applying segmentation algorithm for cell shape reconstruction.
Fusion of Channel State Information and Received Signal Strength for Indoor Localization Using a Single Access Point

: In recent years, indoor localization systems based on ﬁngerprinting have had signiﬁcant advances yielding high accuracies. Those approaches often use information about channel communication, such as channel state information (CSI) and received signal strength (RSS). Nevertheless, these features have always been employed separately. Although CSI provides more ﬁne-grained physical layer information than RSS, in this manuscript, a methodology for indoor localization fusing both features from a single access point is proposed to provide a better accuracy. In addition, CSI amplitude information is processed to remove high variability information that can negatively inﬂuence location estimation. The methodology was implemented and validated in two scenarios using a single access point located in two different positions and conﬁgured in 2.4 and 5 GHz frequency bands. The experiments show that the methodology yields an average error distance of about 0.1 m using the 5 GHz band and a single access point.
The Effect of Ethanol Dip and Modified Atmosphere on Prevention of Botrytis Rot of Table Grapes

Grape (Vitis vinifera) storage requires stringent control of gray mold caused by Botrytis cinerea. The commercial practice is dependent on sulfur dioxide (SO2) as a fumigant, which is applied by various means with well-known advantages and disadvantages. Many alternative technologies were developed over the years, most of them with limited effi cacy or applicability. Modifi ed atmosphere of table grapes suffers from a narrow threshold between control of gray mold and damage to the berries and stems due to high level of carbon dioxide (CO2) within the fi lm-enclosed package. We demonstrated in the past that dipping table grapes in ethanol after harvest has a very pronounced effect on prevention of decay. However, ethanol does not leave a protective residue within the grapes, so it is not expected to prevent latent infections from developing decay nests during prolonged storage. However, if grapes of cultivar Superior were treated with ethanol and then subjected to
Distribution and Roost Selection of Bats on Newfoundland

Abstract We studied the distribution and ecology of male and female Myotis lucifugus (Little Brown Bats) and M. septentrionalis (Northern Long-eared Bats) on Newfoundland, where conditions (e.g., resource availability, abiotic conditions) were expected to be less favorable than in areas where most studies of conspecifics have occurred. We found that both species were patchily distributed and that Northern Long-eared Bats were more widely distributed across the island than previously documented. We located and characterized 36 roost trees from 14 female (6 lactating and 8 non-lactating) Northern Long-eared bats and found that, relative to conspecific populations on mainland North America, female Northern Long-eared Bats on the northern peninsula of Newfoundland roosted in shorter trees with smaller diameters. We also found that roosts used by lactating Northern Long-eared females were in cavities of large-diameter trees that maintained more stable microclimates compared to roosts used by non-lactating females.
