BackgroundStreptococcus pneumoniae, more than 90 serotypes of which exist, is recognized as an etiologic agent of pneumonia, meningitis, and sepsis associated with significant morbidity and mortality worldwide. Immunization with a pneumococcal pep27 mutant (Δpep27) has been shown to confer comp...

Many drugs currently used are covalent inhibitors and irreversibly inhibit their targets. Most of these were discovered through serendipity. Covalent inhibitions can have many advantages from a pharmacokinetic perspective. However, until recently most organisations have shied away from covalent ...

IntroductionChimerism is defined as coexistence of different cell lines in an individual. 46,XX/46,XY chimerism is very rare and exhibits broad range of clinical phenotypes. Most cases are detected at infancy or younger age due to disorders of sex development, while phenotypically normal cases a...

Decolorisation of reactive red 120 (RR120), was investigated using hydrodynamic cavitation (HC). Present works mainly study effect of various geometrical parameters of orifice plates on decolorisation of RR120 in aqueous solution. For this purpose seven orifice plates having different diameter a...

We report development of ZSM-5 nanocatalyst including Fe promoter for decolorization of Reactive Red 120 (RR120) azo dye in a heterogeneous electro-Fenton reaction. The nanocatalysts were characterized by XRD, FT-IR, FE-SEM, N2 adsorption-desorption and NH3-TPD techniques. The influence of diffe...

The effectiveness of ozone combined with ultrasound techniques in degrading reactive red X-3B is evaluated. A comparison among ozone (O3), ultrasonic (US), ozone/ultrasonic (O3/US) for degradation of reactive red X-3B has been performed. Results show that O3/US system was the most effective and ...

The electrochemical coagulation technique (EC) and potentiodynamic polarization tests were used to evaluate the influence of some anions as chloride, sulfate and nitrate on the removal of Reactive Red 43 (RR43) as a model pollutant using aluminum and iron anodes. Higher removal efficiency was ob...

The Fourier Transform Infrared (FT-IR) spectra of 12 dyes have been measured; the dyes had the same chromophore but a different side chain group. The FT-IR characteristic frequencies of vinylsulphone, sulphatoethylsulphone and hydroxyethylsulphone have been recognised in the complex conjugated m...

The photodegradation of Reactive Red 35 dye by artificial UV light was investigated in the presence of titania P-25. Six reaction intermediates were identified and separated by LC/MS, giving insight into mechanistic details and degradation pathways. The degradation process takes place through co...

A study of the catalytic decolourisation of one textile dye by oxidation with H2O2, using different carbon materials as catalysts, is reported. Ten carbon solids, differing both in their texture–structure features and in their surface chemistry properties, were used for this purpose. These are ...

Azo dyes are refractory and recalcitrant contaminants that pose a significant impact on the environment upon releasing to the natural resources. This study focused on the decolorization and biodegradation of water soluble azo dye reactive red (RR2) in an integrated batch mode sequential anaerobi...

This study investigated the electrochemical degradation of C.I. Reactive Red 195 (RR195) in aqueous solution on a Ti/SnO2–Sb/PbO2 electrode. The influence of operating variables on the mineralization efficiency was studied as a function of the current density, the initial pH, the initial concen...

The effects of pH, dye concentration, electron acceptor (hydrogen peroxide, persulfate and copper ions) and hydroxyl radical trap (ethanol) on the decolorization of C.I. Reactive Red 198 using a UV/TiO2 system were determined. Decolorization rate increased as the concentration of persulfate ions...

In this paper, a new type immunochromatographic assay (ICA) based on core-shell red silica nanoparticles (core-shell red SiO2NPs) was proposed and used to detect Escherichia coli O157:H7 (E. coli O157:H7). This is the first report of qualitative ICA for detecting E. coli O157:H7 in phosphate buf...

This study developed a heterogeneous catalyst derived from iron slag (IS) waste containing main constituents of FeO, ZnO and SiO2 for Fenton and ozonation processes to remove an azo dye (Reactive Red 24 (RR24)) from aqueous solutions. It was found that heterogeneous catalytic Fenton and ozonatio...

Irradiation with red light or near-infrared (NIR) lasers can bio-modulate cellular processes or revitalize injured tissues and therefore, widely been used for therapeutic interventions. Mechanistically, this cellular or biological process, referred as Photobiomodulation (PBM), is achieved by the...

Effects of parts of adsorbent, solution pH level, adsorbent dose, particle size, initial dye concentration, temperature, and contact time on the batch adsorption of Reactive Red (RR) 120 on Moringa oleifera seed (MOS) was studied. The surface structure of MOS was characterized using a scanning e...

Doping of nitrogen (N) on carbon materials often requires complicated synthetic steps or specific machinery.
