Doxycycline sensitivity against in vitro cultured Babesia gibsoni was evaluated by real-time PCR and parasitemia. The culture of B. gibsoni was successfully continued and mean parasitemia was 4.63% when in vitro drug sensitivity test was started. The drug sensitivity test by the real-time PCR calculated the gene copy number from cultured sample. Even if the complete growth inhibition was at cer...

Matrix metalloproteinases (MMPs) may limit severely the pulmonary vasodilatory and inotropic effects of adrenomedullin during pulmonary hypertension. While doxycycline inhibits MMPs and prevents the hemodynamic disorders associated with acute pulmonary embolism (APE), no previous study evaluated if doxycycline enhances adrenomedullin-induced pulmonary vasodilation and contributes to the attenua...

BACKGROUND Pilot data have indicated that both doxycycline alone and mifepristone combined with ethinyl estradiol (EE) are effective in stopping episodes of bleeding in Implanon users with troublesome bleeding. We compared four treatments against a placebo in Implanon users and tested whether repeated treatment improved subsequent bleeding patterns. METHOD Implanon users aged 18-45 years were...

The effects of doxycycline were examined on articular cartilage glycosaminoglycan (GAG) release and biphasic mechanical properties following two levels of impact loading at 1 and 2 weeks post-injury. Further, treatment for two continuous weeks was compared to treatment for only the 1st week of a 2-week culture period. Following impact at two levels, articular cartilage explants were cultured fo...

A study was performed to determine the residues in edible tissues of healthy pigs after continuous administration of doxycycline with drinking water for five consecutive days at a dose rate of 10.5 mg doxycycline kg-1 body weight (BW) per day. Quantitation was performed using a validated HPLC method with fluorescence detection. The method was able to separate doxycycline and its 4-epimer, 4-epi...

A case series outlining three young individuals with no history of mental disorder who were treated for skin conditions with doxycycline, but developed suicidal ideation with an outcome of suicide in two of the cases. One of these individuals had CYP2C19*2 heterozygote genotype associated with a diminished cytochrome p450 enzyme activity and two of his siblings had developed severe anxiety prev...

The effects of doxycycline-streptomycin-rifampin versus a standard doxycycline-streptomycin regimen on residual Brucella DNA were compared in 36 acute brucellosis patients. At admission, all patients given triple (n = 22) and double (n = 14) regimens had detectable Brucella DNA with similar mean loads (P = 0.982). At follow-up, 14 to 20 months postpresentation, significantly more patients recei...

background: available evidence shows that tetracycline family has cellular and molecular mechanisms to protect neurons and oligodendrocytes by modulating matrix metalloproteinases. we tried to compare the effectiveness of intramuscular and subcutaneous interferon beta-1a (inf-β1a) in combination with oral doxycycline among patient with relapsing remitting multiple sclerosis (rrms) and secondary...

inhalation delivery of aerosolized antibacterials is preferred over conventional methods of delivery for targeting lung infection. the present study is concerned with the development and characterization of a novel, spray dried, aerosolized, chitosan polyelectrolyte complex (pec) based microparticles containing antibacterials for the treatment of lung infections.chitosan polyelectrolyte complex...
