The Role of Retrotransposons in Gene Family Expansions: Insights from the Mouse \u3ci\u3eAbp\u3c/i\u3e Gene Family

Background: Retrotransposons have been suggested to provide a substrate for non-allelic homologous recombination (NAHR) and thereby promote gene family expansion. Their precise role, however, is controversial. Here we ask whether retrotransposons contributed to the recent expansions of the Androgen-binding protein (Abp) gene families that occurred independently in the mouse and rat genomes. Results: Using dot plot analysis, we found that the most recent duplication in the Abp region of the mouse genome is flanked by L1Md_T elements. Analysis of the sequence of these elements revealed breakpoints that are the relicts of the recombination that caused the duplication, confirming that the duplication arose as a result of NAHR using L1 elements as substrates. L1 and ERVII retrotransposons are considerably denser in the Abp regions than in one Mb flanking regions, while other repeat types are depleted in the Abp regions compared to flanking regions. L1 retrotransposons preferentially accumulated in the Abp gene regions after lineage separation and roughly followed the pattern of Abp gene expansion. By contrast, the proportion of shared vs. lineage-specific ERVII repeats in the Abp region resembles the rest of the genome. Conclusions: We confirmed the role of L1 repeats in Abp gene duplication with the identification of recombinant L1Md_T elements at the edges of the most recent mouse Abp gene duplication. High densities of L1 and ERVII repeats were found in the Abp gene region with abrupt transitions at the region boundaries, suggesting that their higher densities are tightly associated with Abp gene duplication. We observed that the major accumulation of L1 elements occurred after the split of the mouse and rat lineages and that there is a striking overlap between the timing of L1 accumulation and expansion of the Abp gene family in the mouse genome. Establishing a link between the accumulation of L1 elements and the expansion of the Abp gene family and identification of an NAHR-related breakpoint in the most recent duplication are the main contributions of our study

Truck driveline vibration modeling using multi-body system

Prediction of NVH parameters of driveline in construction phase is a significant topic nowadays because it can save time and development costs, but requires more complex mathematical models. This paper describes the use of MBS simulation tool for prediction of driveshaft vibration where shaft is modeled as a flexible body. MBS approach can take into account various input parameters, i.e. unbalanced mass of shaft, geometry deviation from ideal shape, mounting points of eccentricity or contact between the shaft and other parts of the driveline. MBS model of driveshaft was verified by measurement on a real vehicle

FACTORS INFLUENCING STRATEGIC DEVELOPMENT OF INSURANCE BROKERS MARKET İN THE CZECH REPUBLIC

The aim of the paper is to recognise the relationship among Gross Premiums Written and Average Gross Nominal Wage (Average Wage) in the Czech Republic. The literature review has characterised insurance market in the Czech Republic. Based on the secondary data of Czech Insurance Association, Czech Statistical Office and Czech National Bank has been created PESTEL analysis, determined the rate of influence of the factors influencing the insurance brokers, evaluated by scale from 1 to 5. The secondary data for regression analysis has been obtained from annual reports of CNB and CSO in period 1996 to 2015. The method of regression analysis has tested the relationship among average gross nominal wage as one of the macroeconomic factor and the “premiums written “which is used for measurement of the overall insurance market level in the Czech Republic. The model was verified through the economic, statistical and econometric verification. The statistical data has been elaborated in software Gretl. Part discussion and conclusion have been focused to the comparison of obtained results and reaction recommendation on upcoming predicted situations on the market

Gated Graphene Electrical Transport Characterization

Graphene is a very interesting new material, and promises attractive applications in future nanodevices. It is a 2D carbon structure with very interesting physical behavior. Graphene is an almost transparent material that has higher carrier mobility than any other material at room temperature. Graphene can therefore be used in applications such as ultrahigh-speed transistors and transparent electrodes. In this paper, we present our preliminary experiments on the transport behavior of graphene at room temperature. We measured the resistivity of Hall-bar samples depending on gate voltage (backgated graphene). Hysteresis between the forward and backward sweep direction was observed
