introduction: the purpose of this in vitro study was to evaluate the antimicrobial effects of two antibiotics added to ah 26 sealer against enterococcus faecalis (ef). materials and methods: the antimicrobial effects of two antibiotic (amoxicillin and doxycycline) that were added separately to ah 26 sealer was evaluated by using the agar diffusion test and in vitro human root inoculation method...
This study assessed the in vitro antibacterial activity of combinations of amikacin and doxycycline or tigecycline against multidrug-resistant E. coli isolates. Twenty-four different pulsotypes, including 10 extended-spectrum β-lactamase (ESBL)-, 10 carbapenem-resistant, 2 New Delhi Metallo-beta-lactamase (NDM)- and 2 Klebsiella pneumoniae carbapenemase (KPC)-E. coli isolates were collected. Al...
Rats harboring the human angiotensinogen and human renin genes develop preeclamptic features in pregnancy. The preeclamptic rats exhibit a deeper trophoblast invasion associated with a reduced resistance index by uterine Doppler. Doxycycline inhibits matrix metalloproteinase activity. We tested the hypothesis that matrix metalloproteinase inhibition reduces trophoblast invasion with subsequent ...
In this paper functionalized multiwall carbon nanotubes (FMWCNT) were modified using doxycycline, containing reactable nitrogen, which can attach chemically to functionalized MWCNT. The synthesized nano compounds were characterized by Fourier transform infrared spectroscopy (FT-IR) and Raman spectroscopy. These spectrums proved the existence of nitrogen atoms of amide functional groups. The mor...
Doxycycline displays high efficiency for cancer therapy. However, the molecular mechanism is poorly understood. In our previous study, doxycycline was found to suppress tumor progression by directly targeting proteinase-activated receptor 1 (PAR1). In this study, microRNAs were found to be involved in PAR1-mediated anti-tumor effects of doxycycline. Among these miRNAs, miR-17 was found to promo...
BACKGROUND Doxycycline can prevent aortic aneurysms through the inhibition of enzymes that degrade vessel walls. We investigated whether haemodialysis patients who had received one or more courses of doxycycline were at less risk for aneurysms in their vascular accesses than those who had received other antibiotics. METHODS Three hundred and eight patients undergoing chronic maintenance hemod...
OBJECTIVE To generate doxycycline-inducible human tumor necrosis factor α (TNFα)-transgenic mice to overcome a major disadvantage of existing transgenic mice with constitutive expression of TNFα, which is the limitation in crossing them with various knockout or transgenic mice. METHODS A transgenic mouse line that expresses the human TNFα cytokine exclusively after doxycycline administration ...
Doxycycline is a tetracycline that has been licensed for veterinary use in some countries, but no clinical breakpoints are available for veterinary pathogens. The objectives of this study were (i) to establish breakpoints for doxycycline and (ii) to evaluate the use of tetracycline as a surrogate to predict the doxycycline susceptibility of Staphylococcus pseudintermedius isolates. MICs and inh...
