Mycobacterial energy metabolism currently attracts strong attention as new target space for development of anti-tuberculosis drugs. The imidazopyridine Q203 targets the cytochrome bcc complex of the respiratory chain, a key component in energy metabolism. Q203 blocks growth of Mycobacterium tuberculosis at nanomolar concentrations, however, it fails to actually kill the bacteria, which may limi...
in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
The succinate dehydrogenase consists of only four subunits, all nuclearly encoded, and is part of both the respiratory chain and the Krebs cycle. Mutations in the four genes encoding the subunits of the mitochondrial respiratory chain succinate dehydrogenase have been recently reported in human and shown to be associated with a wide spectrum of clinical presentations. Although a comparatively r...
Mitochondrial dysfunction is associated with a spectrum of human disorders, ranging from rare, inborn errors of metabolism to common, age-associated diseases such as neurodegeneration. How these lesions give rise to diverse pathology is not well understood, partly because their proximal consequences have not been well-studied in mammalian cells. Here we provide two lines of evidence that mitoch...
Mitochondrial respiratory chain dysfunction causes a wide range of primary diseases in adults and children, with highly variable organ involvement. Diagnosis involves weighing evidence from a number of sources, including the clinical presentation, metabolic measurements in vivo, imaging studies, analysis of respiratory chain function or enzyme activities in vitro, studies of mitochondrial morph...
Optically inactive gossypol is an effective male antifertility agent in several mammalian species, while optically active (+)-gossypol has no antifertility effect in the rat and hamster. Recently, it was suggested that the mitochondria of spermatogenic cells may be a subcellular target of gossypol. We are reporting the effects of optically inactive gossypol and (+)-gossypol on the respiratory c...
It is known that fluoride produces oxidative stress. Inflammation in bone tissue and an impairment of the respiratory chain of liver have been described in treatments with fluoride. Whether the impairment of the respiratory chain and oxidative stress are related is not known. The aim of this work was to study the effects of fluoride on the production of superoxide radical, the function of the r...
Backgrounds & Objective: Mycoplasmas pneumoniae is responsible for more than 20% of community acquired pneumonia cases and also implicated in acute respiratory infections, such as sore throat, pharyngitis, rhinitis, and tracheobronchitis. Conventional assays for the detection of M. pneumoniae have their limitations, resulting in the need for more accurate diagnostic methods. Molecular methods, ...
Objective(s): Increasing evidence in both experimental and clinical studies suggests that oxidative stress plays a major role in the pathogenesis of multiple sclerosis. The aim of the present work is to investigate the protective effects of erythropoietin against cuprizone-induced oxidative stress. Materials and Methods: Adult male C57BL/6J mice were fed a chow containing 0.2 % cuprizone for 6 ...
