Field suppression of Fusarium wilt and microbial population Shifts in tomato rhizosphere following soil treatment with two selected endophytic bacteria

Two endophytic bacteria, Bacillus subtilis SV41 (KR818071) and B. amyloliquefaciens subsp. plantarum SV65 (KR818073), were assessed under field conditions for their capacity to control tomato Fusarium wilt in tomato and their effects on soil microbial activity. Six months after planting, Fusarium wilt severity, estimated through the vascular browning extent in tomato stems, was significantly reduced by 82.3 and 88.2% compared to control following bacterial treatments. The frequency of F.oxysporum re-isolation from roots, collars and stems was also significantly lowered in treated plants compared to controls. These effects were associated with a significant improvement, by 10.6 to 16.3%over control, in plant height and root fresh weight and an increase in fruit production by 8.4-12.5%. As for microbial activity, F. oxysporum population in the rhizosphere of tomato plants treated with B. subtilis SV41 and B. amyloliquefaciens subsp. plantarum SV65 was reduced by 87.5-91.7%compared to the initial soil (sampled before planting) and by 88.4-92.3% relative to the rhizospheric soil of untreated plants (control soil). A significant enhancement in the total culturable bacterial community was also noted in the rhizosphere of tomato plants treated with both strains compared to initial and control soils where a significant enrichment in Pseudomonas and actinobacteria community was recorded.

Evaluating IBMEC-RJ’s Intranet Usability Using Fuzzy Logic

System usability is a concept that goes beyond the ease of use, and includes several criteria for measurement. This study aims to evaluate the usability and thus the quality of IBMEC-RJ’s Intranet in Rio de Janeiro, Brazil, by the fact that it is of great assistance to teachers and students. The method is applied research through questionnaires. The universe of users was limited by a convenience sample of IBMEC. The methodology that had used Microsoft Excel and Matlab from Mathworks is innovative. Fuzzy logic is a fundamental tool for consolidating and analyzing data.
Undiagnosed microscopic colitis: a hidden cause of chronic diarrhoea and a frequently missed treatment opportunity

Microscopic colitis (MC) is a treatable cause of chronic, non-bloody, watery diarrhoea, but physicians (particularly in primary care) are less familiar with MC than with other causes of chronic diarrhoea. The colon in patients with MC is usually macroscopically normal. MC can only be diagnosed by histological examination of colonic biopsies (subepithelial collagen band >10 µm (collagenous colitis) or >20 intraepithelial lymphocytes per 100 epithelial cells (lymphocytic colitis), both with lamina propria inflammation). The UK National Health Service exerts downward pressure to minimise colonoscopy referrals. Furthermore, biopsies are often not taken according to guidelines. These factors work against MC diagnosis. In this review, we note the high incidence of MC (comparable to ulcerative colitis and Crohn’s disease) and its symptomatic overlap with irritable bowel syndrome. We also highlight problems with the recommendation by National Health Service/National Institute for Health and Care Excellence guidelines for inflammatory bowel diseases that colonoscopy referrals should be based on a faecal calprotectin level of ≥100 µg/g. Faecal calprotectin is <100 µg/g in over half of individuals with active MC, building into the system a propensity to misdiagnose MC as irritable bowel syndrome. This raises important questions—how many patients with MC have already been misdiagnosed, and how do we address this silent burden? Clarity is needed around pathways for MC management; MC is poorly acknowledged by the UK healthcare system and it is unlikely that best practices are being followed adequately. There is an opportunity to identify and treat patients with MC more effectively.
Patterns of Tactical Networking Services

The Cloud Computing services are making their way to the world of tactical networking. According to CDR James Mills (Mills, 2011) the new area of tactical networking, named cloudlets, is shaping up: “Cloudlets are small, portable appliance-like devices akin to a “data center in a box” and include an embedded compute cluster, wireless access point and battery or alternate source power (e.g., solar, wind, etc.). Cloudlets offer the benefit of offloading computation from mobile devices, reduce latency of mobile devices by being in close proximity to the user’s device, and offload data relay costs to the larger cloud/network from the mobile device. ” This chapter describes findings and prototypes of emerging tactical networking services, which were identifiable based on unique experimental studies of tactical networking. The described findings would be helpful in structuring tactical cloud services for the variety manned-unmanned sensor networking applications.
E VENT - BASED PATTERN DETECTION IN ACTIVE DENDRITES

Many behavioural tasks require an animal to integrate information on a slow timescale that can exceed hundreds of milliseconds. How this is realized by neurons with membrane time constants on the order of tens of milliseconds or less remains an open question. We show, how the interaction of two kinds of events within the dendritic tree, excitatory postsynaptic potentials and locally generated dendritic plateau potentials , can allow a single neuron to detect speciﬁc sequences of spiking input on such slow timescales. Our conceptual model reveals, how the morphology of a neuron’s dendritic tree determines its computational function, which can range from a simple logic gate to the gradual integration of evidence to the detection of complex spatio-temporal spike-sequences on long timescales. As an example, we illustrate in a simulated navigation task how this mechanism can even allow individual neurons to reliably detect speciﬁc movement trajectories with high tolerance for timing variability. We relate our results to conclusive ﬁndings in neurobiology and discuss implications for both experimental and theoretical neuroscience. rise to complex non-linear computation. We demonstrate how this mechanism enables individual neurons to solve difﬁcult, behaviorally relevant tasks that are commonly studied on the network-level, such as the detection of variable input sequences or the integration of evidence on long timescales. We also characterize computation in our model using rate-based analysis tools, demonstrate why our proposed mechanism of dendritic computation cannot be detected under this analysis and suggest an alternative based on plateau timings. The interaction of plateau events in dendritic trees is, according to our argument, an elementary principle of neural computation which implies the need for a fundamental change of perspective on the computational function of neurons. rectangular pulses of unit magnitude and ﬁxed duration τ synapse and τ dendrite
Shade tolerance and mycorrhizal type may influence sapling susceptibility to conspecific negative density dependence

The maintenance of tree diversity has been explained by multiple mechanisms. One of the most thoroughly studied is conspecific negative density dependence, in which specialist plant enemies reduce survivorship of seeds, seedlings or saplings located near adult conspecifics. Although there is much support that conspecific negative density dependence occurs in temperate forests, only a subset of the species investigated thus far exhibit this recruitment pattern. It remains unclear what drives differential susceptibility to conspecifics among tree species. Previous investigators have considered shade tolerance and mycorrhizal type (arbuscular mycorrhizal vs. ectomycorrhizal association) as two traits that might explain differential susceptibility to conspecific negative density dependence. Here, we test whether these two plant traits predict susceptibility of tree saplings to conspecific negative density dependence in a temperate hardwood forest using three responses: spatial point patterns of saplings, sapling growth and sapling survival. Spatial patterns of saplings indicate that shade tolerant species are less sensitive to conspecifics than shade intolerant species, but show no differences based on mycorrhizal type. Conversely, shade tolerant saplings exhibit reduced growth, but not survival, when located in areas with high conspecific density. We interpret this finding in light of the conservative functional strategies of shade tolerant species, which typically have low leaf nitrogen levels and slower growth to divert resources to tissue defence against enemies. We found an effect of mycorrhizal type interacting with adult conspecific density, where arbuscular mycorrhizal species show a greater reduction in growth than ectomycorrhizal species in areas dense with conspecifics. Synthesis. We conclude that the shade tolerance level and the mycorrhizal type of temperate forest saplings may influence how their growth and survival respond to the adult conspecific trees in their neighbourhoods.
Identifikasi parasit darah pada ayam buras di Pasar Inpres Naikoten Kota Kupang

Important blood parasites in chickens are members of the phylum Apicomplexa, which are Haemoproteus, Leucocytozoon and Plasmodium. Blood parasite can cause low productivity and death in poultry farms. This study aimed to identify and determine the prevalence of blood parasites infection in poultry in Naikoten traditional market, Kupang city. The sampling technique was purposive sampling.

Timing and Intensity of Steer Use on Old World Bluestem (Bothriochloa Ischaemum) and Blue Grama (Bouteloua Gracilis) in Southern Mixed-Grass Prairie

Yellow bluestem (Bothriochloa ischaemum), an invasive species, was introduced as a forage species and as a roadside grass for erosion control. Yellow bluestem can negatively interact with native grasslands and reduce biodiversity. Livestock tend to avoid yellow bluestem after accumulation of standing lignified tissue, particularly at the end of the growing season. Mowing has been used in pasture situations to remove excess grass for hay and over coarse grass left from the previous season. It is essential to understand the role livestock play as either a catalyst for control or preventing further invasion of yellow bluestem. Quantification of the timing and intensity of yellow bluestem defoliation by livestock after mowing compared to native grass has not been previously documented. To evaluate this, I recorded steer utilization of yellow bluestem and blue grama (Bouteloua gracilis) in a southern mixed grass prairie following two mowing treatments during 2012-2013. I also recorded cover by litter. In 2012, mean utilization of blue grama (12%) was lower than mean utilization of yellow bluestem (22%), but in 2013, mean utilization of blue grama (20%) was higher than mean utilization of yellow bluestem (15%). Timing of utilization of yellow bluestem was different than was suggested previously, with utilization of yellow bluestem occurring late in the season. These data could be used to help assess the potential shifts in steer utilization of native rangelands where yellow bluestem is present and aid in making future grassland management decisions. However, the system that I worked with experienced a high degree of variation in temperature and precipitation between years, a longer-term experiment could distinguish between year to year utilization variation and an overall trend in yellow bluestem utilization.
Meat Quality on Sentul Cocks with Different Immunoglobulin Yolk Concentrations

Sentul cocks is one of the native chicken breeds in Indonesia which is originally raised by Villagers in Ciamis District, West Java. Healthy chicken cells can function properly, especially in the metabolic process. Healthy chickens are expected to produce better muscle development. IgY is a protein molecule substance that can neutralize a number of microorganisms that cause infection. The purpose of this study was to evaluate the effect of IgY concentration on physicochemical and organoleptic qualities of meat. This study used 20 cocks, 4th month ages, consist of 2 treatments (IgY concentrations above 9.30 ± 0.45 mg mL-1 and IgY concentrations below 9.30 ± 0.45 mg mL-1). The variable observed include physicochemical and organoleptic quality of meat. The study was used completely randomized design. Data were analyzed by t-test. The result concluded that cocks with concentrations above 9.30 ± 0.45 mg mL-1 produced meat with lower malonaldehyde. The low content of malonaldehyde in meat shows that the meat produced is healthier.
Extraction and detection of saponin-enriched fractions from different plants of North-western Himalayas, India

The different plant species throughout the world have been used in traditional medicines, and some of their bioactive constituents including saponins have excellent biological activities for new drug development. The present study was designed to explore four plants of North-western Himalayas, Asparagus adscendens Roxb. (AA) (fruits), Silene inflata Sm. (SI) (whole plant), Sapindus mukorossi Gaertn. (SM) (pericarp of fruit) and Chlorophytum borivilianum (CB) (leaves) for saponin content. The total crude saponin-rich fraction yields were 8.0±2.564%, 4.0±1.486 %, 20.0±2.845%, and 9.8±1.439%, respectively. The presence of saponins in plants was confirmed by foam test and spectrophotometry. The foam forming capacity of AAS, SI, SM and CB was significantly lower than standard saponin. The concentration of saponins was found to be 560 ±2.426 μg/ml (AA), 240 ±0.536 μg/ml (SI), 820±1.846 μg/ml (SM) and 110 ±1.664 μg/ml (CB) in the samples. The saponins from these plants could be used in formulation of various drugs, nutraceuticals or other uses, thereby avoiding overexploitation the plant(s) currently in use for the purpose.
Variación genética y fenotípica en psammodromus algirus (lagartija colilarga): implicaciones ecológicas y evolutivas

Esta tesis trata de, una vez explorados los rasgos fenotipicos que pueden interpretarse como adaptaciones locales, contestar a preguntas que tienen que ver con como responde el genoma a las presiones selectivas divergentes que subyacen a la diferenciacion de dichos rasgos. En general, no se pretende descubrir la base genetica de la adaptacion a los gradientes ambientales que generan adaptacion local; lo que se busca es desentranar como la evolucion provee la variacion genetica necesaria para afrontar diferentes retos ecologicos en una especie capaz de subsistir en una gran variedad de ambientes. Mediante escaneos genomicos a gran escala, conseguimos definir fracciones del genoma relacionadas con la adaptacion a distintos ambientes, revelando patrones de convergencia y divergencia adaptativa gracias a procesos tanto de mantenimiento de diversidad genetica ancestral como de innovacion genetica. Tras conseguir descifrar la huella de la seleccion natural en el genoma, nos preguntamos acerca de las dinamicas geneticas responsables de los umbrales adaptativos que configuran los limites de la distribucion de la especie, como proceso que depende de forma directa de la adaptacion local. Por ultimo, realizamos un estudio de los efectos geneticos de la fragmentacion del habitat en una metapoblacion de lagartijas, en la que el aumento de la homocigosidad en los fragmentos de menor tamano dio lugar a una perdida de aptitud (eficacia biologica o aptitud) en los individuos afectados. Ademas, nuestro trabajo nos permitio aumentar significativamente la potencia estadistica de unos pocos marcadores neutrales (6 loci de microsatelites utilizados para sustentar las correlaciones entre fragmentacion, homocigosis y aptitud), validandolos con una base de datos genomica con mas de 73,000 variantes geneticas.
NMDAR-dependent emergence of behavioral representation in primary visual cortex

Neocortical sensory areas are generally thought to faithfully represent external stimuli. However, a growing body of evidence suggests that cortical networks exhibit considerable functional plasticity over multiple temporal scales, allowing them to modify their output to reflect ongoing behavioral demands. Nevertheless, the dynamics of sensory and non-sensory representations during acquisition of stimulus-guided behavior are not well understood. We performed longitudinal 2-photon imaging of activity in primary visual cortex (V1) of mice learning a conditioned eyeblink task. We found that both excitatory and inhibitory neurons robustly encode the visual stimulus throughout training despite a significant experience-dependent reduction in response magnitude. In contrast, both pyramidal neurons and parvalbumin-expressing interneurons exhibit emergence of behavioral representation during learning. The plasticity of visual response magnitude and behavioral representation is abolished following loss of NMDA-type glutamate receptors. Overall, our findings demonstrate that V1 networks can dynamically multiplex distinct behaviorally relevant representations over the course of learning.
Security issues with pervasive computing frameworks

The deployment of pervasive computing systems inevitably raises security concerns. The ability of such systems to synthesise partial information and react to situations without explicit user interaction, confirmation or consent means that issues of trust, safety and privacy become exceptionally important. We examine the general issues inherent in any pervasive computing system, focusing on the hazards that emerge from the interactions between different forms of context. We apply this analysis to one particular context-aware infrastructure, and use this to derive some important research topics for future investigation.
Performance of the CardioChekTM PA and Cholestech LDX(R) point-of-care analysers compared to clinical diagnostic laboratory methods for the measurement of lipids : cardiovascular topic

Point-of-care (POC) blood testing is intended to provide results more rapidly than can be obtained from a central laboratory. Precision and accuracy of the CardioChek PA and Cholestech LDX analysers were compared to clinical diagnostic laboratory methods. In 100 patients, total cho lesterol (TC), triglycerides (TG), HDL cholesterol (HDL-C) and LDL cholesterol (LDL-C) levels were measured by both analysers and compared to those analysed by the National Health Laboratory Service (NHLS) laboratory. Data were evaluated for conformance with National Cholesterol Education Program (NCEP) guidelines. Results were grouped into low, middle and high ranges and were similar to those obtained by the NHLS, except in the high range where TC and LDL-C levels were under-read by both analysers. All analytes measured by both analysers correlated significantly with NHLS (p < 0.0001). With the exception of LDL-C, both analysers showed reasonable compliance with NCEP goals for coefficients of variation and bias measurements. Both analysers met NCEP guidelines for all analytes at two clinical cut-off points. We concluded that, compared to NHLS methods, performance of the CardioChek PA and Cholestech LDX analysers is acceptable and that they offer healthcare professionals a rapid, POC method for the measurement of lipids.

Mapping gene flow between ancient hominins through demography-aware inference of the ancestral recombination graph

The sequencing of Neanderthal and Denisovan genomes has yielded many new insights about interbreeding events between extinct hominins and the ancestors of modern humans. While much attention has been paid to the relatively recent gene flow from Neanderthals and Denisovans into modern humans, other instances of introgression leave more subtle genomic evidence and have received less attention. Here, we present an extended version of the ARGweaver algorithm, ARGweaver-D, which can infer local genetic relationships under a user-defined demographic model that includes population splits and migration events. This Bayesian algorithm probabilistically samples ancestral recombination graphs (ARGs) that specify not only tree topology and branch lengths along the genome, but also indicate migrant lineages. The sampled ARGs can therefore be parsed to produce probabilities of introgression along the genome. We show that this method is well powered to detect the archaic migration into modern humans, even with only a few samples. We then show that the method can also detect introgressed regions stemming from older migration events, or from unsampled populations. We apply it to human, Neanderthal, and Denisovan genomes, looking for signatures of older proposed migration events, including ancient humans into Neanderthal, and unknown archaic hominins into Denisovans. We identify 3% of the Neanderthal genome that is putatively introgressed from ancient humans, and estimate that the gene flow occurred between 200-300kya. We find no convincing evidence that negative selection acted against these regions. We also identify 1% of the Denisovan genome which was likely introgressed from an unsequenced hominin ancestor, and note that 15% of these regions have been passed on to modern humans through subsequent gene flow.
