1. Ca2+/Calmodulin-dependent kinase II delta B is essential for cardiomyocyte hypertrophy and complement gene expression after LPS and HSP60 stimulation in vitro
Inflammation plays an important role in the development of cardiovascular diseases (CVDs), suggesting that the immune system is a target of therapeutic interventions used for treating CVDs. This study evaluated mechanisms underlying inflammatory response and cardiomyocyte hypertrophy associated with bacterial lipopolysaccharide (LPS)- or heat shock protein 6

2. Efficacy of relacin combined with sodium hypochlorite against Enterococcus faecalis biofilms
Abstract Objective Relacin is a synthetic molecule that targets RelA, an essential protein in a conserved bacterial stress response system. It was shown to inhibit bacterial growth. The aims of this study were to evaluate the antimicrobial effect of relacin combined with sodium hypochlorite (NaOCl) on Enterococcus faecalis biofilms and to evaluate the cyto

3. Inactivation of MarR gene homologs increases susceptibility to antimicrobials in Bacteroides fragilis
ABSTRACT Bacteroides fragilis is the strict anaerobic bacteria most commonly found in human infections, and has a high mortality rate. Among other virulence factors, the remarkable ability to acquire resistance to a variety of antimicrobial agents and to tolerate nanomolar concentrations of oxygen explains in part their success in causing infection and colon

4. Bacterial immunostat: Mycobacterium tuberculosis lipids and their role in the host immune response
Abstract: The lipid-rich cell wall of Mycobacterium tuberculosis is a dynamic structure that is involved in the regulation of the transport of nutrients, toxic host-cell effector molecules, and anti-tuberculosis drugs. It is therefore postulated to contribute to the long-term bacterial survival in an infected human host. Accumulating evidence suggests that M

5. The diversity of citrus endophytic bacteria and their interactions with Xylella fastidiosa and host plants
Abstract The bacterium Xylella fastidiosa is the causal agent of citrus variegated chlorosis (CVC) and has been associated with important losses in commercial orchards of all sweet orange [Citrus sinensis (L.)] cultivars. The development of this disease depends on the environmental conditions, including the endophytic microbial community associated with the

6. Effect of biologically treated petroleum sludge on seed germination and seedling growth of Vigna unguiculata (L.) Walp. (Fabaceae)
The present investigation was carried out to study the response of different concentrations of treated petroleum sludge on seed germination, root and shoot length and tolerance of Vigna unguiculata (L.) Walp. The biologically treated petroleum sludge with bacterial consortium showed 54.8% reduction in total petroleum hydrocarbons. Treated sludge was utilized

7. Pathophysiology of bacterial infection of the central nervous system and its putative role in the pathogenesis of behavioral changes
Invasion of the central nervous system (CNS) by microorganisms is a severe and frequently fatal event during the course of many infectious diseases. It may lead to deafness, blindness, cerebral palsy, hydrocephalus, cognitive impairment or permanent neurological dysfunction in survivors. Pathogens can cross the blood-brain barrier by transcellular migration,

8. Aspectos da regulação metabólica bacteriana em resposta a herbicidas: um enfoque ao sistema antioxidante / Aspects of bacterial metabolic regulation in response to herbicides: an antioxidant system approach
A contaminação ambiental por pesticidas é uma preocupação cada vez mais presente, como indicam estudos que detectam frequentemente estes compostos em água e solo, e visto a importância destes, faz-se necessário a compreensão do seu impacto em organismos não alvo. Dessa forma, o estudo da resposta adaptativa bacteriana a herbicidas vem de encontro c

9. Bacterial exopolysaccharide and biofilm formation stimulate chickpea growth and soil aggregation under salt stress
To compensate for stress imposed by salinity, biofilm formation and exopolysaccharide production are significant strategies of salt tolerant bacteria to assist metabolism. We hypothesized that two previously isolated salt-tolerant strains Halomonas variabilis (HT1) and Planococcus rifietoensis (RT4) have an ability to improve plant growth, These strains can

10. Caracterização de cepas de Escherichia coli contendo diferentes alelos rpoS. / Characterization of Escherichia coli strains carrying different rpos alleles.
Escherichia coli can be found in many different habitats and has to be prepared to survive and grow under unfavorable conditions. Bacteria adaptation to different growth conditions requires an efficient control of gene expression. One of the primary forms of gene expression control is the competition between different sigma factors for the binding to the cor

11. The osmoprotective effect of some organic solutes on Streptomyces sp. mado2 and nocardiopsis sp. mado3 growth
The response of two marine actinomycetes such as Streptomyces sp. MADO2 and Nocardiopsis sp. MADO3 to osmotic stress in minimal medium M63 and in glycerol-asparagine medium (ISP5) was studied. The two strains were moderately halophilic and the behavior of the strain Streptomyces sp. MADO2 and Nocardiopsis sp. MADO3 towards the salt stress was varied depends

12. Mecanismos envolvidos com a sobrevivência de Xylella fastidiosa em condições de estresse e efeito de N-Acetil-L-Cisteína em seu biofilme / Mechanisms involved in Xylella fastidiosa survival under stress conditions and effect of N-Acetyl-L-Cysteine on its biofilm
Xylella fastidiosa is a Gram-negative bacterium that causes several diseases in different plant species, including citrus variegated chlorosis (CVC) in sweet orange (Citrus sinensis L. Osbeck), whose economic damage is of millions of dollars annually. The symptoms development has been associated with the blockage of xylem vessels caused by bacterial biofilm
