Nucleic acids can be sequenced by a chemical procedure that partially damages the nucleotide positions at their base repetition. Many methods have been reported for the selective recognition of guanine. The accurate identification of guanine in both single and double regions of DNA and RNA remains a challenging task. Herein, we present a new, non-toxic and simple method for the selective recogn...

The aim of this study was to develop a protocol for the production of fungal bio-pesticides with high efficiency, low cost, and non-polluting fermentation, while also increasing their survival rate under field conditions. This is the first study to develop biocontrol Trichoderma harzianum transformants TS1 that are resistant to benzimidazole fungicides. Agricultural corn stover and wheat bran w...

Effects of respirable aerosols of sulfuric acid, ammonium sulfate, sodium sulfite, and ammonium persulfate on lungs of rats are reviewed. The literature regarding interactions between ozone or nitrogen dioxide and acidic aerosols (ammonium sulfate, sulfuric acid) is discussed. An unexpected interaction between nitrogen dioxide and sodium chloride aerosol is also discussed. An attempt is made to...

In this paper, we demonstrate for the first time that poly(m-phenylenediamine) (PMPD) nanospheres and nanorods can be selectively synthesized via chemical oxidation polymerization of m-phenylenediamine (MPD) monomers using ammonium persulfate (APS) as an oxidant at room temperature. It suggests that the pH value plays a critical role in controlling the the morphology of the nanostructures and f...

This study was carried out in two stages. In the first stage; 2-oxo-2-phenylethyl-2-aminobenzoate (OPA) compound, which an aniline derivative, synthesized by starting appropriate components. Then, poly(OPA) obtained via chemical polymerization of OPA presence ammonium peroxydisulfate (APS) as initiator and DMF solvent. Poly(OPA)/Bentonite (BNT) nanocomposite effectively dispersing inorganic nan...

In this research, novel conductive nanocomposites containing urethane acrylate (UA) andpolyaniline/copper (II) oxide nanocomposites (PANi-CuO) were synthesized. At firstpolyaniline/CuO nanocomposites with different amount of CuOnanoparticleswere prepared bychemical oxidationpolymerization of aniline using ammonium peroxydisulfate as an oxidizingagent. Afterward, UA-PANi-...

BACKGROUND Cosmetics for bleaching, waving/relaxing and dyeing hair contain well-known allergens, leading to a substantial number of cases of allergic contact dermatitis. OBJECTIVE To compare the frequency of important contact allergens (i) between two distinct groups of exposed patients, and (ii) with previous surveillance data. METHODS On the basis of data collected by the Information Net...
