The type VI secretion system (T6SS) is a virulence factor for many Gram-negative bacteria. Salmonella genus harbors five phylogenetically distinct T6SS loci encoded in Salmonella Pathogenicity Islands (SPIs) SPI-6, SPI-19, SPI-20, SPI-21 and SPI-22, which are differentially distributed among serotypes. The T6SSs encoded in SPI-6 and SPI-19 contribute to pathogenesis of serotypes Typhimurium and...

In this paper, we provide a Lagrangian analysis of the anomalies in the moisture transport during two important drought events (1989/1990 and 2003) configured over the Danube River Basin (DRB) region. Firstly, we identified the drought episodes that occurred over the DRB in the period of 1980–2014 through the Standardized Precipitation Evapotranspiration Index (SPEI). SPEI was calculated using ...

Jiangsu is an important agricultural province in China. Winter wheat, as the second major grain crop in the province, is greatly affected by moisture variations. The objective of this study was to investigate whether there were significant trends in changes in the moisture conditions during wheat growing seasons over the past decades and how the wheat yields responded to different moisture leve...

This research addresses issues relating to the implementation of software process improvement (SPI) initiatives. A number of advances have been made in the development of software process improvement (SPI) standards and models, e.g. Capability Maturity Model (CMM), more recently CMMI, and ISO's SPICE. However, these advances have not been matched by equal advances in the adoption of these stand...

This paper summarises an updated climate change trends analysis—developed for the period from 1 October 1864 to 30 September 2021 within scope of a Horizon 2020-funded project increase resilience in European coastal cities—for representative site Lisbon Metropolitan Area (Portugal). By using long ground-based daily records rainfall and surface temperature at Lisboa-Geofísico climatological stat...

The ETS protein Spi-1/Pu.1 plays a pivotal and widespread role throughout hematopoiesis in many species. This study describes the identification, characterization, and functional analysis of a new zebrafish spi transcription factor spi-1-like (spi-1l) that is expressed in primitive myeloid cells, erythro-myelo progenitor cells, and in the adult kidney. Spi-1l functions genetically downstream of...

The comprehensive assessment of climatic and hydrological droughts in terms of their temporal and spatial evolutions is very important for water resources management and social development in the basin scale. To study the spatial and temporal changes of climatic and hydrological droughts and the relationships between them, the SPEI and SDI are adopted to assess the changes and the correlations ...

Hanan Selman Hessan and Ahmed Mohammed Abbas 563 Abstract Immune status was examined after tonsillectomy operations in 30 children with recurrent acute tonsillitis, their ages ranged between 3-10 years, were clinically diagnosed by ENT surgeon at AlHilla General Teaching Hospital and 10 apparently healthy children were included as a control in the study which lasted from February to May 2011 .I...

The acquisition of new genetic traits by horizontal gene transfer and their incorporation into preexisting regulatory networks have been essential events in the evolution of bacterial pathogens. An example of successful assimilation of virulence traits is Salmonella enterica, which acquired, at distinct evolutionary times, Salmonella pathogenicity island 1 (SPI-1), required for efficient invasi...
