Application of Fourier transform-based algorithms to resolve spectral overlapping for UV spectrophotometric co-assay of spiramycin and metronidazole in tablets

To resolve UV spectral overlapping of spiramycin and metronidazole in binary mixtures, Fourier transform-based algorithms were tested. Both UV spectra and ratio spectra were subjected to rapid Fourier transform-based first-order differentiation and discrete Fourier change i. e. Such signal transformations resulted in linear calibration graphs for any drug in the concentration range of 6. 25 to 25 mg/L with R2 > 0. 990. When determining spiramycin and metronidazole in their coated tablets, the developed UV spectrophotometric techniques made no difference in terms of accuracy and precision in comparison with the RP-HPLC reference system.

Simultaneous Determination of Metronidazole and Ranitidine Using an Activated GCE Decorated with Electrochemically Reduced Graphene Oxide

In a non-KNO 3 design, the rGO-AGCE was produced by electrochemically reducing a graphene oxide-modified AGCE by electrochemically reducing a graphene oxide-modified AGCE using linear swipe voltammetry. Due to the potential electrostatic interaction between the functional groups of rGO and AGCE, a stable electrode surface was created, which also helps in catalyzing the reduction of MT and RT's reaction. At the rGO-AGCE, the voltametric response of MT and RT were determined by differential pulse voltammetry and CV. From scan rate analysis, the charge transfer coefficient and the total number of electrons associated with the reduction process were calculated.

From the Cover: Metronidazole prevents reactivation of latent Mycobacterium tuberculosis infection in macaques

Targeting Mycobacterium tuberculosis bacilli in low-oxygen microenvironments, such as caseous granulomas, has been hypothesized to reduce therapy for acute tuberculosis and prevent latent infection reactivation. After TNF neutralization, the first time we knew that on low-dose M. tuberculosis infection, equal amounts of cynomoles macaques have active disease or latent infection, and that latently infected animals were reactivated. We now demonstrate that chemoprophylaxis of latently infected cynomolgus macaques with 6 mo of isoniazid effectively prevented anti-TNF antibody-induced reactivation by using this model. We also discovered that MTZ addition to INH/RIF effectively treated animals with active TB within 2 mo. Our results in the nonhuman primate model of active and latent TB supports are showing bacteria in hypoxic environments for preventing latent infection reactivation and possibly reducing the duration of therapy in active TB.
