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...
The in vitro susceptibility of 14 European Chlamydia psittaci strains from turkeys to the antibiotics doxycycline and enrofloxacin was tested. For doxycycline the MIC ranged from 0.05 to 0.2 microg/ml, with an average of 0.1 microg/ml. For enrofloxacin the MIC was 0.25 microg/ml. Acquired resistance was not detected against doxycycline and enrofloxacin.
OBJECTIVES Evidence suggests that doxycycline might have disease-modifying properties in osteoarthritis. However, the clinically relevant question as to whether doxycycline also modifies symptoms in knee osteoarthritis is unanswered. The objective of this study was to investigate the effectiveness of doxycycline on pain and daily functioning in symptomatic knee osteoarthritis. METHODS A 24-we...
Acute lung injury (ALI) was one of the major complications after cardiopulmonary bypass (CPB). Matrix metalloproteinases (MMPs) play an important role in ALI following CPB. In this study, we investigated the effects of doxycycline (DOX), a potent MMP inhibitor, on MMP-9 and ALI in the rat model of CPB. 48 adult male Sprague-Dawley rats were randomized into four groups: group I (Control group, u...
OBJECTIVES To evaluate the effects of systemic doxycycline on clinical and microbiological parameters of diabetic subjects with chronic periodontitis. METHODS This 9-month multi-center, randomized, parallel, single-blinded study was conducted from different hospitals in Riyadh, Saudi Arabia between April 2010 and December 2010. A total of 76 diabetic subjects with chronic periodontitis were r...
We present the case of a 45 year old woman with acute Q fever pneumonia who progressed to the chronic phase of the disease despite azithromycin therapy. A trial of doxycycline was halted because of severe allergy and she was put on clarithromycin and later moxifloxacin. Failure of both drugs required desensitization to doxycycline with escalating doses. After two-year treatment with doxycycline...
BACKGROUND Single-dose azithromycin is recommended over multi-dose doxycycline as treatment for chlamydial infection. However, even with imperfect adherence, doxycycline is more effective in treating genital and rectal infection. Recently, it has been suggested that autoinoculation from the rectum to the genitals may be a source of persistent chlamydial infection in women. We estimated the impa...
OBJECTIVES The objective of the present study was to compare the efficacy of gentamicin given alone or combined with doxycycline with that of standard combination therapies in BALB/c mice experimentally infected with the Brucella melitensis vaccine strain Rev 1. METHODS A standard broth microdilution method was applied to determine the susceptibility of strain Rev 1 to the clinically most rel...
Received July 10, 2006 Abstract Objectives: To briefly outline the development and reasons for the decline in the clinical use of tetracyclines, and to consider if the side-effects of doxycycline a contra-indication to its use. Data Sources: Literature search of MEDLINE from 1950 to 2005. Study Selection: Literature and data related to doxycycline, tetracycline and tooth discolouration. Data Ex...
OBJECTIVES Doxycycline is commonly used in medicine for its bacteriostatic antimicrobial properties. Recent studies have reported that doxycycline also has anti-inflammatory effects. Matrix metalloproteinase (MMP)-9 has been found to be involved in the physiological and pathological process of inflammatory airway disease. Phorbol 12-myristate 13-acetate (PMA), a protein kinase C activator, is k...
