Although recent evidence suggests that reduced nitric oxide (NO) production may be involved in salt-induced hypertension, the specific NO synthase (NOS) responsible for the conveyance of salt sensitivity remains unknown. To determine the role of inducible NOS (NOS II) in salt-induced hypertension, we treated Dahl salt-resistant (DR) rats with the selective NOS II inhibitor 2-amino-5,6-dihydro-6...

The current study focuses on the development of the modified surface of the alumina by anionic surfactant sodium dodecyl sulfate. The synthesized Surfactant Modified Alumina (SMA) effectively associated with dye molecules and amended their properties. The triphenylmethane (CBB) and thiazine dyes (MB) were selected as a simulated dye wastewater system. The removal was carried out by adsorpti...

objective(s): recently we reported that the soybean 15-lipoxygenase (slo) inhibitory activity of pyrimido[4,5-b][l,4]benzothiazines largely depends on the orientation of sulfur atom of thiazine core towards feiii-oh in the active site pocket of the enzyme with subsequent oxidation of sulfur to sulfoxide. in this paper the results of a comparative study on the slo inhibitory activities of the me...

Methylene blue (MB) is a cationic thiazine dye with the chemical name tetramethylthionine chloride. It has a characteristic deep blue color in the oxidized state, but the reduced form, leukomethylene blue (LMB), is colorless. Methylene blue has been widely used in a variety of clinical settings to identify anatomic (Manhes et al., ’94; Sills and Zinkham, ’94; Barber et al., ’95) and pathologic ...

The activity of the newly synthesized azaphenothiazines: tricyclic 10-substituted dipyridothiazines 1-9, pentacyclic 6-substituted diquinothiazines 10-22 and hexacyclic diquinothiazinium salt 23 was tested on 55-60 in vitro cell lines. The cell lines included nine types of cancer: leukemia, non-small cell lung cancer, colon cancer, CNS cancer, melanoma, ovarian cancer, renal cancer, prostate ca...

The degradation products of Cefepime dihydrochloride that emerged throughout stress stability studies have been determined, identified and characterized. The two new impurities were detected by gradient reverse-phase high performance liquid chromatography (HPLC), and Impurity-I was formed in the range from 0.2 to 11.0% and Impurity-II range from 0.2 to 3.5%. These impurities have been identifie...
