In this study, a series of g-C3N4 nanosheets were prepared by various thermal oxidative etching times from four different precursors (urea, melamine, dicyandiamide and thiourea). The physicochemical properties these analyzed in detail using scanning electron microscopy (SEM), X-ray diffraction (XRD), photoluminescence emission spectra, Fourier transform infrared spectroscopy (FTIR), Brunauer–Em...

Abstract Graphite-carbon nitride (g-C 3 N 4 ) was prepared by thermocondensation, and g-C /BiVO material (GCB) /CNTs composite (GCC) were doping different contents of BiVO carbon nanotubes (CNTs) with samples, respectively. Then, , CNTs, samples doped to prepare ternary (GCBC). In the performance experiment, Sulfamethoxazole (SMZ) used as degradation evaluate photocatalytic reaction kinetics eq...

The electrochemical oxidation of sulfamethazine (SMZ) has been studied at a multi-walled carbon nanotubes modified glassy carbon electrode (MWCNT-GCE) by cyclic voltammetry. This modified electrode (MWCNT-GCE) exhibited excellent electrocatalytic behavior toward the oxidation of SMZ as evidenced by the enhancement of the oxidation peak current and the shift in the anodic potential to less posit...

Sir—Toxoplasmosis is a disease that is highly transmissible to D ϩ /R Ϫ patients (i.e., patients who are seronegative for Toxoplasma gondii IgG antibodies and who receive a heart transplant from donors who are seropositive for T. gondii IgG antibodies). This disease, along with disseminated aspergillosis, is associated with the highest mortality rate attributable to an infectious complication i...

The ability of natural clinoptilolite and its modified forms were studied for removal of PAHs from n-paraffin. Surfactant modified zeolite (SMZ) was obtained by modifying clinoptilolite with hexadecyltrimethylammonium ion. Homoionic forms of zeolite were obtained by ion exchange process using inorganic salts of desirable cations (e.g. Ag+, Fe3+…). Nat...

We developed a simple hydrothermal technique for the fabrication of flexible integrated composite containing cerium vanadate (CeVO4) and multi-walled carbon nanotubes (MWCNTs). The CeVO4/MWCNTs possessed good conductivity interesting electrochemical catalytic performance when immobilized on glassy electrode (GCE). This CeVO4/MWCNTs-GCE sensor provided excellent analytical detection sulfonamide ...

The efficacies of trimethoprim (TMP)-sulfamethoxazole (SMZ), TMP-dapsone, dapsone, and pentamidine were compared for the prevention of Pneumocystis carinii pneumonia in the corticosteroid-treated-rat model. While 11 (73%) of 15 untreated control animals had P. carinii pneumonia after 10 weeks of immunosuppression, none of the animals given 125 mg of dapsone per kg daily, weekly, biweekly, or mo...

In The Gambia co-trimoxazole is used widely to treat children with an acute respiratory infection (ARI). Because malaria may sometimes be mistaken for ARI, some children with malaria are treated with co-trimoxazole. Therefore, we investigated the sensitivity of Gambian isolates of Plasmodium falciparum to this drug. Six days after the start of treatment with co-trimoxazole 3.3% of blood films o...

BACKGROUND AND OBJECTIVES The aim of this study was to determine the role of host factors and bacterial virulence genes in the development of pyelonephritis caused by Escherichia coli in renal transplant (Tx) recipients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A total of 328 E. coli isolates from cases of cystitis (Cys; n=239) or pyelonephritis (PN; n=89), with 169 from renal Tx recipie...
