Ulcerative colitis (UC) is a nonspecific inflammatory disorder characterized by oxidative and nitrosative stress, leucocyte infiltration and up-regulation of pro-inflammatory cytokines. Mitogen-activated protein kinases (MAPKs), such as the p38 and the c-Jun N-terminal kinase (JNK) modulate the transcription of many genes involved in the inflammatory(More)
The synthesis of 1,4-naphthoquinone derivatives is of great interest since these compounds exhibit strong activity as antimalarial, antibacterial, antifungal and anticancer agents. A series of 50 naphthoquinone derivatives was synthesized and evaluated for antibacterial and antifungal activity against Escherichia coli, Pseudomonas aeruginosa, Enterococcus(More)
The bioavailability of soy isoflavones depends on the composition of the microflora for each subject. Bacteria act on different isoflavones with increased or reduced absorption and cause biotransformation of these compounds into metabolites with higher biological activity. S-equol is the most important metabolite and only 25–65 % of the population have the(More)
To the Editor—The presence of drug-resistant organisms and their variability between hospitals and even within different areas of the same hospital requires a good knowledge of local microbiological epidemiology. The development of antimicrobial stewardship programs (ASPs) in the hospital setting has been encouraged by scientific societies worldwide," and(More)
Outpatient urine samples are among the most commonly processed in a microbiology laboratory, which involves a high economic burden. The aim of this study was compare cost and efficiency to process uropathogens between MicroScan system (2010-2011) versus a chromogenic medium and the disk diffusion method (2013-2014). In the first period, a total 9918(More)
