Abstract:
Antibiotics are added to animal feeds as prophylactic agents and to encourage weight gain in livestock. However, there is concern that the widespread use of antibiotics in animal agriculture encourages for the selection of resistance genes and has contributed to the rise of multiply antibiotic resistant strains of pathogenic bacteria. For this reason, there is interest in quantifying antibiotics in environmental samples. The determination of three antibiotics in swine waste, namely chlortetracycline, tetracycline and oxytetracycline, using LC-MS with electrospray ionization is presented here i

Abstract:
For six decades tetracyclines have been successfully used for their broad spectrum antibiotic effects. However, non-antibiotic effects of tetracyclines have been reported. The anti-inflammatory effects of tetracycline drugs have been investigated in the context of a range of inflammatory diseases including sepsis and a number of neurodegenerative diseases. This thesis investigates the effects of a range of clinically important tetracyclines (oxytetracycline, doxycycline, minocycline and tigecycline) on the ability of the J774.2 cell line to produce nitric oxide when stimulated with the bacteri

Pseudomonas aeruginosa grew in the presence of 10 $ mu$g/ml tetracycline (TC) or chlorotetracycline (CTC) in a minimal medium containing Mg$ sp{++}$. Growth is inhibited, with a six-fold increase in length of the lag phase. Cells revert to sensitivity when returned to antibiotic-free medium. Substitution of Mg$ sp{++}$ in the growth medium of CTC-resistant strains with Ca$ sp{++}$ and Sr$ sp{++}$ resulted in dramatic changes in growth and cell mass of cultures. Exposure of CTC-grown cells to EDTA did not result in cell lysis. SDS-PAGE of outer membrane proteins of resistant cells revealed loss

The results detailed herein – including successful C-ring-forming Michael–Claisen cyclizations of numerous modified AB precursors with just a few of the extraordinarily diverse D-ring precursors known to be effective nucleophiles in this key coupling reaction – represent the first steps towar

The spread of tetracyclines through agricultural systems is causing the present bacteria to develop antibiotic resistance. The spread of this bacteria, as well as the tetracycline antibiotics in the environment is dangerous because these antibiotics pose health hazards for humans. The overuse of antibiotics, which are added to livestock feed, results in the antibiotics being released into the environment via animal feces. In this research, we have attempted to design an analytical method to isolate antibiotics from agricultural wastes with subsequent detection using liquid chromatography and m

Abstract:
Matrix metalloproteinases (MMPs), such as collagenases, are a family of enzymes capable of degrading most constituents of the extracellular matrix. MMPs are thought to be involved in the aetiopathogenesis of tendon rupture. Additionally, failure of healing has in some instances been associated with elevated levels of MMPs. We have studied (a) the effects of the MMP-inhibitor doxycycline on healing of tendons and intestines in experimental models and (b) systemic levels of MMPs and their endogenous inhibitors (TIMPs) in patients with tendon rupture. In the first study, systemic doxycycline trea

Synthese de la bikaverine, 6,11-dihydroxy 3,8-dimethoxy 1-methyl benzo(b) xanthene 7,10,12-trione. La bikaverine est un pigment a squelette benzoxanthone derive de la naphtazarine a proprietes antiprotozoaire et antimitotique, isole de divers fusarium. Cette these illustre une nouvelle methode de synthese basee sur la condensation thermique des bases de mannich. Ce travail debute par la synthese de naphtazarines diversement substituees par des groupes hydroxyles, halogenes, ou methoxyles. Une etude de la structure des naphtazarines substituees en-2 a ete effectuee. Le second chapitre est consa

Abstract:
A triple blind randomized controlled trial was undertaken in a Brazilian Amazon region (Cuiaba-MT), to compare the effectiveness and side effects of oral artesunate (7 days, total dose = 0.75 g) plus tetracycline (7 days, total dose = 10.5 g) (AT) and oral quinine (3 days, total dose = 6 g) plus tetracycline (7 days, total dose = 10.5 g) (QT). Eligible patients had uncomplicated P. falciparum malaria; age $ geq$ 14 years; no previous malaria treatment related to the present attack; and, if women, indication of absence of pregnancy. Clinical exam and blood tests were performed at baseline (day
