Urinary tract physiological conditions promote ciprofloxacin resistance in low-level-quinolone-resistant Escherichia coli
(American Society for Microbiology, 2016-07-01)
Escherichia coli isolates carrying chromosomally encoded low-level-quinolone-resistant (LLQR) determinants are frequently found in urinary tract infections (UTIs). LLQR mutations are considered the first step in the ...

Cellular Response to Ciprofloxacin in Low-Level Quinolone-Resistant Escherichia coli
(Frontiers Media, 2017)
Bactericidal activity of quinolones has been related to a combination of DNA fragmentation, reactive oxygen species (ROS) production and programmed cell death (PCD) systems. The underlying molecular systems responsible ...

Inoculum Effect on the Efficacies of Amoxicillin-Clavulanate, Piperacillin-Tazobactam, and Imipenem against Extended-Spectrum -Lactamase (ESBL)-Producing and Non-ESBL-Producing Escherichia coli in an Experimental Murine Sepsis Model
(American Society for Microbiology, 2013-04)
Escherichia coli is commonly involved in infections with a heavy bacterial burden. Piperacillin-tazobactam and carbapenems are among the recommended empirical treatments for health care-associated complicated intra-abdominal ...

Risk Factors and Prognosis of Nosocomial Bloodstream Infections Caused by Extended-Spectrum-B-Lactamase-Producing Escherichia coli
(American Society for Microbiology, 2010-05)
Extended-spectrum-B-lactamase (ESBL)-producing Escherichia coli (ESBLEC) is an increasing cause of community and nosocomial infections worldwide. However, there is scarce clinical information about nosocomial bloodstream ...

Evidence of melatonin synthesis and release by mast cells. Possible modulatory role on inflammation
(Elsevier, 2010)
Mast cells take part of armamentarium immunologic for host defense against parasitic and bacterial infections. They are derived from bone marrow progenitors and can be activated by immunological and chemical stimuli in ...

Obatoclax and Paclitaxel Synergistically Induce Apoptosis and Overcome Paclitaxel Resistance in Urothelial Cancer Cells
(MDPI, 2018)
Paclitaxel is a treatment option for advanced or metastatic bladder cancer after the failure of first-line cisplatin and gemcitabine, although resistance limits its clinical benefits. Mcl-1 is an anti-apoptotic protein ...

Heterologous viral expression systems in fosmid vectors increase the functional analysis potential of metagenomic libraries
(Nature Publishing Group, 2013)
The extraordinary potential of metagenomic functional analyses to identify activities of interest present in uncultured microorganisms has been limited by reduced gene expression in surrogate hosts. We have developed vectors ...

Population pharmacokinetics and pharmacodynamics of fosfomycin in non-critically ill patients with bacteremic urinary infection caused by multidrug-resistant Escherichia coli
(Elsevier, 2018)
Objectives: To describe the population pharmacokinetics of fosfomycin for patients with bacteraemic urinary tract infection (BUTI). The analysis identified optimal regimens on the basis of pharmacodynamic targets and ...

Plant growth promotion in cereal and leguminous agricultural important plants: From microorganism capacities to crop production
(2014)
Plant growth-promoting rhizobacteria (PGPR) are free-living bacteria which actively colonize plant roots, exerting beneficial effects on plant development. The PGPR may (i) promote the plant growth either by using their ...
