The Eurasian wild boar (Sus scrofa) is the main wild reservoir of the Mycobacterium tuberculosis complex in Mediterranean woodlands and a key risk factor for cattle tuberculosis (TB) breakdowns. Wild boar vaccination therefore has the potential to be a valuable tool for TB control. We tested two orally delivered vaccines, heat-inactivated Mycobacterium bovis (IV) and BCG, in four sites (two per vaccine type: one Managed and one Natural or unmanaged) during four years. TB was also monitored in 15 unvaccinated sites (spatial control), as well as in all sites from one year prior to intervention (temporal control)...

RNAseq reads from cape-gooseberry plants (Physalis peruviana) infected with Fusarium oxysporum f. sp. physali (Foph) were mapped against the lineage-specific transcriptome of Fusarium oxysporum f. sp. lycopersici (Fol) to look for putative effector genes. Homologues of Fol SIX1 (designated SIX1a and SIX1b), SIX7, SIX10, SIX12, SIX15 and Ave1 were identified. The near identity of the Foph and Fol SIX7, SIX10 and SIX12 genes and their intergenic regions suggest that this gene cluster may have undergone recent lateral transfer...

Alternating treatments designs (ATDs) are single-case experimental designs entailing the rapid alternation of conditions, and the specific sequence of conditions is usually determined at random. The visual analysis of ATD data entails comparing the data paths formed by connecting the measurements from the same condition. Apart from visual analyses, there are at least two quantitative analytical options also comparing data paths. On option is a visual structured criterion (VSC) regarding the number of comparisons for which one conditions has to be superior to the other to consider that the difference is not only due to random fluctuations...

One pertinent complication in bacterial infection is the growth of biofilms, i.e., communities of surface-adhered bacteria resilient to antibiotics. Photodynamic inactivation has been proposed as an alternative to antibiotic treatment; however, novel techniques complementing standard efficacy measures are required. Herein, we present an approach employing multiphoton microscopy complemented with Airyscan super-resolution microscopy, to visualize the distribution of curcumin in Staphylococcus epidermidis biofilms...

Osseointegration, including the foreign body reaction to biomaterials, is an immune-modulated, multifactorial, and complex healing process in which various cells and mediators are involved. The buildup of the osseointegration process is immunological and inflammation-driven, often triggered by the adsorption of proteins on the surfaces of the biomaterials and complement activation. New strategies for improving osseointegration use coatings as vehicles for osteogenic biomolecules delivery from implants. Natural polymers, such as gelatin, can mimic collagen I and enhance the biocompatibility of a material...

Echinococcosis is a worldwide anthropozoonosis which is highly endemic over large animal husbandry areas in northwestern China. The current clinical therapeutic medicine against echinococcosis is albendazole, although it caused serious side effects in patients. The component in traditional Chinese herb medicine, Sophora moorcroftiana alkaloids (SA), is thought to be a potential drug to treat echinococcosis. In order to explore the effect and mechanism of SA treatment against echinococcosis, we established animal echinococcosis model and treated rats with albendazole alone, alkaloids alone, and combined therapy...

Background: Previous investigations of product design broadly link aesthetic, functional, and symbolic designs to sales growth, high turnover, and market share. However, the effect of product design dimensions on consumer willingness-to-buy (WTB) and word-of-mouth (WOM) is virtually ignored by consumer researchers. Similarly, whether the consumption experience can differentiate the effect of the three product design dimensions on WTB and WOM is completely unknown. Using categorization theory as a lens, our study aims to explore the effect of product design dimensions on consumer WTB and WOM directly and indirectly through the moderation of the consumption experience...

Disulfide bonds influence stability and activity of many proteins. In Escherichia coli the DsbA and DsbB enzymes promote disulfide bond formation. Other bacteria, including the Actinobacteria, use instead of DsbB the enzyme VKOR (Vitamin K Epoxide Reductase), which is found either fused to or encoded in the same operon as a dsbA -like protein. Mycobacterium tuberculosis and other gram-positive Actinobacteria secrete to the cell envelope many proteins with even numbers of cysteines. These organisms have predicted oxidoreductases and VKOR orthologs...

The progression of cystic fibrosis (CF) from an acute to a chronic disease is often associated with the conversion of the opportunistic pathogen Pseudomonas aeruginosa from a nonmucoid form to a mucoid form in the lung. This conversion involves the overproduction of the exopolysaccharide alginate, whose production is under control of the AlgT/U sigma factor. This factor is regulated posttranslationally by an extremely unstable process and has been commonly attributed to mutations in the algT/U gene. By exploiting this unstable phenotype, we isolated 34 spontaneous nonmucoid variants arising from the mucoid strain PDO300, a PAO1 derivative containing the mucA22 allele commonly found in mucoid CF isolates...

Human innate immunity employs cellular and humoral mechanisms to facilitate rapid killing of invading bacteria. The direct killing of bacteria by human serum is mainly attributed to the activity of the complement system that forms pores in Gram-negative bacteria. Although Gram-positive bacteria are considered resistant to serum killing, we here uncover that normal human serum effectively kills Enterococcus faecium. Comparison of a well-characterized collection of commensal and clinical E. faecium isolates revealed that human serum specifically kills commensal E...

Immune modulators are known to be produced by matured biofilms and during different stages of planktonic growth of Staphylococcus aureus. Little is known about immune modulator production during the early stages of biofilm formation, thus raising the question: how does S. aureus protect itself from the innate immune responses at these stages? Therefore, we determined the production of the following immune modulators: chemotaxis inhibitory protein of staphylococci (CHIPS), staphylococcal complement inhibitor (SCIN), formyl peptide receptor-like 1 inhibitor, gamma-hemolysin component B, leukocidin D, E, and S, staphylococcal superantigen-like protein 1, 3, 5 and 9, and staphylococcal enterotoxin A...

REVIEW
Irena Sniecinski, Jerard Seghatchian
Artificial Intelligence (AI) reflects the intelligence exhibited by machines and software. It is a highly desirable academic field of many current fields of studies. Leading AI researchers describe the field as "the study and design of intelligent agents". McCarthy invented this term in 1955 and defined it as "the science and engineering of making intelligent machines". The central goals of AI research are reasoning, knowledge, planning, learning, natural language processing (communication), perception and the ability to move and manipulate objects...

PURPOSE: Endometrial cancer is the sixth most common female cancer worldwide. There is little evidence that routine hospital surveillance increases survival or decreases morbidity following treatment. Gynaecology Oncology clinical nurse specialists (CNSs) are ideally placed to provide the care, information and support to enable women with a gynaecological cancer to self-manage and live well. A multi-centre randomised controlled trial (RCT) compared hospital follow-up (HFU) with telephone follow-up (TFU) by CNSs...

BACKGROUND: The SOS response is an almost ubiquitous response of cells to genotoxic stresses. The full complement of genes in the SOS regulon for Vibrio species has only been addressed through bioinformatic analyses predicting LexA binding box consensus and in vitro validation. Here, we perform whole transcriptome sequencing from Vibrio cholerae treated with mitomycin C as an SOS inducer to characterize the SOS regulon and other pathways affected by this treatment. RESULTS: Comprehensive transcriptional profiling allowed us to define the full landscape of promoters and transcripts active in V...

Activation of the alternative complement cascade has been implicated in the pathogenesis of age related macular degeneration (AMD) and Alzheimer's disease (AD). Amyloid β (Aβ), a component of drusen, may promote complement activation by inhibiting CFI bioactivity. We determined whether Aβ reduced CFI bioactivity and whether antibodies against Aβ including a monoclonal antibody, GSK933776 could restore CFI bioactivity. We also measured CFI bioactivity in plasma of subjects with AMD and AD. In support of the GSK933776 development program in AMD (geographic atrophy), we developed a quantitative assay to measure CFI bioactivity based on its ability to cleave C3b to iC3b, and repeated it in presence or absence of Aβ and anti-Aβ antibodies...
