Distribution of Plasma Cells and Alpha-Naphthyl Acetate Esterase - Positive Lymphocytes in the Reproductive Organs of Female Cats in Anoestrus, Oestrus and Pseudopregnancy

SUMMARY The distribution of plasma cells and alpha naphthyl acetate esterase (ANAE) positive lymphocytes in the reproductive tract and ovaries of cats in anoestrus, oestrus and pseudopregnancy was determined using histochemical methods. For plasma cell determination, tissue samples were fixed in formolalcohol for 48 hours, embedded in paraffin and six-micrometer-thick sections stained with methyl green-pyronine. For ANAE demonstration, tissue samples were fixed in formol-sucrose fixative (pH 6.8), stored for 22 hours at +4 C and then additionally fixed in Holt’s solution for 22 hours at +4 C. Cryostat sections of 8 μm thickness were stained for ANAE activity at pH 6.2. The number of plasma cells was significantly lower (P<0.05) in the uterine corpus than the uterine horn of anoestrus cats. Plasma cell numbers were significantly higher (P<0.05) in the ovarian cortex and medulla of the pseudopregnancy group than in the anoestrus and oestrus groups. The density of ANAE-positive lymphocytes was significantly (P<0.05) greater in the uterus and ovaries of oestrous and pseudopregnancy cats than anoestrous cats. It was concluded that the stage of oestrous cycle and pseudopregnancy could be responsible for changing the distribution of plasma cells and ANAE-positive lymphocytes in reproductive tract tissues and ovaries of female cats.

An improved employability skills model and its compliance through vocational educational system in Bahrain

The globalisation along with the interdependence of various economies has resulted in creating extra dimension to the employability skills requirements. Various socio-economic indicators have increased the pressure on vocational education sector and changed it from supply driven to demand driven by the labour market requirements to minimise the existing employability skills gap. The paper presents a study that has been conducted to identify the existing skills gap between School Based Learning (SBL) and Work Based Learning (WBL) in Technical and Vocational Education (TVE) System in Bahrain by asking teachers, Human Resources departments from industry, and industrial supervisors to complete questionnaires. Their answers have been analysed quantitatively and qualitatively. Based on these drawn conclusions, an improved employability skills model has been developed which shows the importance of the required skills. This model will be the basis for suggested modifications in SBL and WBL structure in TVE in Bahrain.

Extension of the Southern Hemisphere Atmospheric Radiocarbon Curve, 2120–850 Years BP: Results from Tasmanian Huon Pine

Decadal samples of dendrochronologically dated pine (Lagorostrobos franklinii) from the Stanley River basin, Tasmania, have been radiocarbon dated between 2120–850 yr BP. This data set overlaps and extends the current Southern Hemisphere record, which covers the period 110–995 yr BP. There is good agreement between the 2 records between 995–850 yr BP, between sample replicates and with consensus values for standards. As in the younger data set, we find evidence for a distinct but variable offset between the Southern Hemisphere data and IntCal04; although this is likely due to real temporal variability in the interhemispheric offset, further work is planned to rule out possible laboratory or sample preparation differences.
HYDROMECHANICAL RESPONSES OF A DECOMMISSIONED BACKFILLED TUNNEL DRILLED INTO A PORO-VISCOELASTIC MEDIUM

This paper is an extension of earlier papers (Wong et al., 2008a, b) which sought to investigate the poroelastic and poro-viscoelastic behaviour of a ground medium following the closing of a spherical cavity, whereas the focus here is for a long horizontal tunnel with a circular section. It presents Laplace transform analytic solutions for the time dependent hydromechanical responses of a decommissioned and backˆlled deep tunnel drilled into a poro-viscoelastic host medium. Both the backˆll, which is assumed as poroelastic, and the host medium are supposed saturated with water. The solutions developed and inverted numerically to obtain the responses in time domain are used to study the eŠects of lining support deterioration, the backˆll stiŠness and of the host medium viscosity. The convergence of the tunnel leads to the expulsion of water from the backˆll into the host medium resulting in corresponding transient responses. Each of the key parameters studied can have the eŠect of either attenuating or accentuating the transient and long term hydromechanical responses by delaying or shortening the dissipation period depending on the direction of change taken by the parameter value. The solutions presented in this paper permit an assessment of the relative importance of these parameters. Comparisons are also drawn between a tunnel and a spherical cavity of identical radius. Generally speaking, the implications of lining support, backˆll stiŠness and viscosity of ground medium are more signiˆcant in terms of the resulting hydromechanical responses, for the tunnel than for the spherical cavity.
Why is Trichodesmium abundant in the Kuroshio

Abstract. The genus Trichodesmium is recognized as an abundant and major diazotroph in the Kuroshio, but the reason for this remains unclear. The present study investigated the abundance of Trichodesmium spp. and nitrogen fixation together with concentrations of dissolved iron and phosphate in the Kuroshio and its marginal seas. We performed the observations near the Miyako Islands, which form part of the Ryukyu Islands, situated along the Kuroshio, since our satellite analysis suggested that material transport could occur from the islands to the Kuroshio. Trichodesmium spp. bloomed (> 20 000 filaments L−1) near the Miyako Islands, abundance was high in the Kuroshio and the Kuroshio bifurcation region of the East China Sea, but was low in the Philippine Sea. The abundance of Trichodesmium spp. was significantly correlated with the total nitrogen fixation activity. The surface concentrations of dissolved iron (0.19–0.89 nM) and phosphate (
What Do the Papers Sell? A Model of Advertising and Media Bias

We model the market for news as a two-sided market where newspapers sell news to readers who value accuracy and sell space to advertisers who value advert-receptive readers. In this setting, monopolistic newspapers under-report or bias news that sufficiently reduces advertiser profits. Paradoxically, increasing the size of advertising eventually leads competing newspapers to reduce advertiser bias. Nonetheless, advertisers can counter this effect if able to commit to news-sensitive cut-off strategies, potentially inducing as much bias as in the monopoly case. We use these results to explain contrasting historical and recent evidence on commercial bias and influence in the media. Copyright © The Author(s). Journal compilation © Royal Economic Society 2009.
Modeling the e!ect of nitrogen "xation on carbon and nitrogen #uxes at BATS

Recent geochemical estimates of N -"xation in the North Atlantic ocean indicate rates that are signi"cantly higher than those derived from direct observations. In this paper di! erent N -"xation rate scenarios are explored using a one-dimensional, biogeochemical model that includes an explicit representation of Trichodesmium. This model reproduces most of the observed interannual variability in phytoplankton production and generates seasonal Trichodesmium biomass and N -"xation cycles similar to those observed at BATS. Two solutions are presented, one where the N -"xation rate is increased enough to reproduce the observed summertime drawdown of DIC, and a second where it is tuned to reproduce the observed sediment trap #uxes. The high N -"xation solution reproduces the seasonal and interannual variability in DIC concentrations quite accurately and generates N -"xation rates that agree with direct rate measurements from 1990 and recent geochemical estimates. However, this solution generates export #uxes that are more than 4 times higher than those observed, and predicts the development of DON and DOC anomalies in late summer/early fall that have not been observed. In contrast, the low N -"xation solution generates trap #uxes that are approximately correct, but overestimates the summertime DIC concentrations by 20}30 mol/kg. Both solutions indicate that there is signi"cant interannual variability in N -"xation at BATS and that the rates were much lower in 1995}1996 than in the previous six years. It is suggested that this variability is linked to decadal-scale #uctuations in the North Atlantic climate. 2001 Elsevier Science Ltd. All rights reserved.
Genotyping of African swine fever virus (ASFV) isolates associated with disease outbreaks in Uganda in 2007

Samples from infected domestic pigs associated with an outbreak of African swine fever (ASF) in three districts of central Uganda in 2007 were confirmed as being infected with African swine fever virus (ASFV) using a P72 gene-based polymerase chain reaction amplification (PCR) assay combined with restriction analysis. None of the sera collected from pigs with clinical symptoms were positive using the OIE serological prescribed tests. However, seven haemadsorbing viruses were isolated in macrophage culture and genotyped by partial p72 and full length p54-gene sequencing. Four of these viruses were isolated directly from serum samples. All the viruses were classified within the domesticpig cycle-associated p72 and p54 genotype IX which also includes viruses responsible for ASF outbreaks in Kenya in 2006 and 2007 and Uganda in 2003. To define virus relationships at higher resolution, typing was performed by analysis of tetrameric amino acid repeat regions within the central variable region (CVR) of the B602L gene. Ugandan isolates sequences exhibited 100% identity to viruses isolated from outbreaks in Kenya in 2007. The identity was greater than the viruses obtained from an earlier outbreak in Kenya in 2006. This provides further evidence that genetically similar ASFV virus within p72 Genotype IX may be circulating between Kenya and Uganda.
Density-based clustering of information networks by substructure optimization

Information networks, such as biological or social networks, contain groups of related entities, which can be identified by clustering. Density-based clustering (DBC) differs from vertex-partitioning methods in that some vertices are classified as noise. This approach is useful in practice to classify groups of related entities within noisy networks. The baseline DBC method involves constructing a maximal spanning forest (MSF) and deleting edges having weights below a threshold, leaving the connected components as clusters. In large networks, the data may contain large scale variances in the noise density level, which causes the baseline method to perform poorly. We investigate whether clustering within substructures of the MSF can improve the result. We present a new set of similarity measures for weighted networks that allow the MSF to connect vertices that are not connected in the original network. We convert the MSF to a hierarchy and merge it bottom-up by optimizing an objective function to produce a flat clustering. We present two new objective functions based on density and irregularity measures. Experiments show that the new similarity measures help to normalize noise density levels and outperform traditional set-based similarity measures; that the proposed substructure optimization method improves over the baseline in networks with many classes; and that DBC outperforms vertex-partitioning methods for classification in noisy networks. The results of the irregularity objective are promising, as it scales with the number of vertices, whereas objectives such as density or modularity scale with the number of edges.
In vitro cytotoxicity of chemical preservatives on human fibroblast cells

Preservatives are widely used substances that are commonly added to various cosmetic and pharmaceutical products to prevent or inhibit microbial growth. In this study, we compared the in vitro cytotoxicity of different types of currently used preservatives, including methylparaben, imidazolidinyl urea (IMU), and sodium benzoate, using the human newborn fibroblast cell line CCD1072Sk. Of the tested preservatives, only IMU induced a reduction in cell viability, as shown using the MTT assay and propidium iodide staining (IMU>;methylparaben>;sodium benzoate). IMU was shown to promote homeostatic alterations potentially related to the initiation of programed cell death, such as decreased mitochondrial membrane potential and caspase-3 activation, in the treated cells. Methylparaben and sodium benzoate were shown to have a very low cytotoxic activity. Taken together, our results suggest that IMU induces programed cell death in human fibroblasts by a canonical intrinsic pathway via mitochondrial perturbation and subsequent release of proapoptotic factors.

Effects of a Microcystis aeruginosa bloom and bacterivory on bacterial abundance and activity in a eutrophic reservoir

We investigated the changes in bacterioplankton abundance, composition, and fractions of cells incorporating leucine associated with a Microcystis aeruginosa bloom and enhanced protozoan grazing in a eutrophic reservoir. Bacterial community composition and leucine incorporation were studied by means of fluorescence in situ hybridization and microautoradiography. To alter the levels of protozoan grazing and the interactions of bacteria with the M. aeruginosa bloom, a manipulation experiment using size-fractionation and dialysis bag techniques was conducted. Samples collected from the Microcystis-poor dam area and the Microcystis-rich middle part of the reservoir were incubated as <0.8 μm, <5 μm, and unfiltered treatments in dialysis bags at their collection sites and, in parallel, one of each of the treatments from one site was transferred to and incubated at the other site. The sample transfer from the dam to the middle part induced a decrease in abundances and doubling times of total bacteria, Betaproteobacteria, and of the R-BT065 cluster (a subgroup of Betaproteobacteria), whereas the transfer to the dam station revealed the opposite trends. In the presence of flagellates and the M. aeruginosa bloom, both abundance and fractions of cells incorporating leucine of Betaproteobacteria and of the R-BT065 cluster transferred to the middle station decreased dramatically, while members of the Sphingobacteria-Flavobacteria lineage became the dominant part of the community. While Gammaproteobacteria accounted for a minor proportion of the total community, their relative proportions and activity increased at the middle station, likely being stimulated by the increased resource availability.
MRI to Assess Arrhythmogenic Cardiomyopathy

Cardiomyopathies are diseases of the myocardium associated with cardiac dysfunction. The latest report of the World Health Organization classifies them according to the dominant pathophysiology (Table 1). The diagnosis of cardiomyopathy has been greatly improved in recent years by non-invasive imaging techniques. Cardiovascular magnetic resonance, or CMR, is now firmly established in clinical and research cardiovascular medicine as a tool for evaluating cardiomyopathy.
Top-quark production measurements

Recent measurements of top-quark production at hadron colliders are reviewed. The inclusive top-quark pair production is determined at four centre-of-mass energies at Tevatron and LHC with experimental uncertainties that are close to the uncertainties in theoretical calculations at next-to-next-to-leading order in QCD. Several differential measurements are performed and compared to simulation. Production of single top quarks is studied in the three different production channels. Top-quark pair production with neutral and charged vector bosons has been observed by the LHC experiments. Finally, production of additional heavy flavour quark pairs ($b\bar{b}$, $t\bar{t}$) is studied or searched for.
A Survey of Econometric Methods for Mixed-Frequency Data

The development of models for variables sampled at different frequencies has attracted substantial interest in the recent econometric literature. In this paper we provide an overview of the most common techniques, including bridge equations, MIxed DAta Sampling (MIDAS) models, mixed frequency VARs, and mixed frequency factor models. We also consider alternative techniques for handling the ragged edge of the data, due to asynchronous publication. Finally, we survey the main empirical applications based on alternative mixed frequency models.
Coparenting in Fragile Families

Nonmarital childbearing has increased dramatically in the U.S. since the early 1960s, rising from 6% of all births in 1960 to fully 40% in 2007 (Hamilton, Martin, & Ventura, 2009). Whereas similar trends have occurred in many developed nations, the U.S. stands out in the extent to which such births are associated with socioeconomic disadvantage and relationship instability. This has given rise to a new term ? fragile families,? which we define as unmarried couples who have a child together. The increase in fragile families reflects changes not only in the initial context of births but also in the fundamental nature and patterns of childrearing.
Monitoring glacier albedo as a proxy to derive summer and annual surface mass balances from optical remote-sensing data

Abstract. Less than 0.25 % of the 250 000 glaciers inventoried in the Randolph Glacier Inventory (RGI V.5) are currently monitored with in situ measurements of surface mass balance. Increasing this archive is very challenging, especially using time-consuming methods based on in situ measurements, and complementary methods are required to quantify the surface mass balance of unmonitored glaciers. The current study relies on the so-called albedo method, based on the analysis of albedo maps retrieved from optical satellite imagery acquired since 2000 by the MODIS sensor, on board the TERRA satellite. Recent studies revealed substantial relationships between summer minimum glacier-wide surface albedo and annual surface mass balance, because this minimum surface albedo is directly related to the accumulation–area ratio and the equilibrium-line altitude. On the basis of 30 glaciers located in the French Alps where annual surface mass balance data are available, our study conducted on the period 2000–2015 confirms the robustness and reliability of the relationship between the summer minimum surface albedo and the annual surface mass balance. For the ablation season, the integrated summer surface albedo is significantly correlated with the summer surface mass balance of the six glaciers seasonally monitored. These results are promising to monitor both annual and summer glacier-wide surface mass balances of individual glaciers at a regional scale using optical satellite images. A sensitivity study on the computed cloud masks revealed a high confidence in the retrieved albedo maps, restricting the number of omission errors. Albedo retrieval artifacts have been detected for topographically incised glaciers, highlighting limitations in the shadow correction algorithm, although inter-annual comparisons are not affected by systematic errors.
Running head: BEYOND SINGLE SYLLABLES

The study assessed the eye movements of 60 adult German readers during silent reading of target words, consisting of 2 and 3 syllables, embedded in sentences. The first objective was to assess whether the inhibitory effect of first syllable frequency, which was up to now primarily shown for isolated words, generalizes to natural reading. The second objective was to assess the effect of orthographic similarity. First syllable frequency was defined phonologically and was based on the SUBTLEX norms for spoken language [Brysbaert et al. (2011). The word frequency effect: A review of recent developments and implications for the choice of frequency estimates in German. Experimental Psychology, 58, 412–424]. Orthographic similarity was indexed by orthographic Levenshtein distance neighborhood frequency [Yarkoni, T. , Balota, D. & Yap, M. (2008). Moving beyond Coltheart’s N: A new measure of orthographic similarity. Psychonomic Bulletin & Review, 15, 971-979]. We found inhibitory effects for first syllable frequency and for orthographic neighborhood frequency. First syllable frequency affected first fixation duration which was considered as reflecting early effects in visual word recognition. Orthographic neighborhood frequency affected “late” measures. These findings show that, first, the effect of first syllable frequency does generalize to silent reading. Second, the effect of orthographic neighborhood frequency, up to now investigated only for short words in the context of English, does generalize to multisyllabic words in the German orthography. Relating the effects to the individual reading rate of the participants revealed that the effects were consistent in fast readers, but highly variable in slow readers.
