Abstract:

This paper involves the synthesis of new oxazepine derivatives by multi-reaction steps. The first step synthesis azo derivative from 2-naphthol with 3-aminoacetophenone. The second step was the condensation reaction between ketone group of the azo compound and different primary aromatic amines (4-amino phenol, 3-nitro aniline and 4-methyl aniline) to yiled new azo Schiff base compounds (S1-S3) respectively. In the final step, Oxazepine compounds (L1-L3)and (L4-L6)were prepared from reaction imine compounds (S1-S3) with maleic and phthalic anhydride in toluene as solvent. All these derivatives

Abstract:

Chemicals safety control and ecological properties have become a priority for the textile industry in order to avoid the negative effects on humans and environment. The increasing interest for toxicology of textiles is determined by the presence of dangerous compounds in clothes generated from dyeing and finishing processes. In order to protect human health, European Regulations as Oeko Tex Standard 100 and REACH Regulation limit the presence of dangerous chemicals, such as aromatic amines, generated by reductive cleavage of azo dyes, by no more than 30 mg/kg of textile material.

The co-occurrence of multiple mycotoxins, including aflatoxin B1 (AFB1), zearalenone (ZEN) and deoxynivalenol (DON), widely exists in cereal-based animal feed and food. At present, most reported mycotoxins degrading enzymes target only a certain type of mycotoxins. Therefore, it is of great significance for mining enzymes involved in the simultaneous degradation of different types of mycotoxins. In this study, a dye-decolorizing peroxidase-encoding gene BsDyP from Bacillus subtilis SCK6 was cloned and expressed in Escherichia coli BL21/pG-Tf2.

Given the low concentration of THC in human breath, sensitive analytical methods are required to further evaluate its utility and window of detection.

Abstract:

The presence of arsenic in marine samples was first reported over 100 years ago, and shortly thereafter it was shown that common seafood such as fish, crustaceans, and molluscs contained arsenic at exceedingly high concentrations. It was noted at the time that this seafood arsenic was probably present as an organically bound species because the concentrations were so high that if the arsenic had been present as an inorganic species it would certainly have been toxic to the humans consuming seafood. Investigations in the late 1970s identified the major form of seafood arsenic as arsenobetaine [

However, ELISA can react with the metabolites of the parent compound and its structurally related compounds. In this study, we investigated the cross-reactivity of the oxytetracycline

Abstract:

Antimicrobial compounds have been successfully used to control many plant and animal diseases. Recently, oxytetracycline (OTC) and streptomycin have been approved for the treatment of Huanglongbing in citrus. Since the application of OTC is under strict regulations, several methods have been developed to determine and monitor its levels in the environment including high-performance liquid chromatography, ELISA, colorimetric, and fluorometric assays. In this study, we developed a fluorometric method for the determination of OTC in plant tissues based on its complexation with europium. Our preli

Abstract:

The emergence of antibiotic-resistant bacteria has become a major concern worldwide. This trend indicates the need for alternative agents to antibiotics, such as natural compounds of plant origin. Using agar disc diffusion and minimum inhibitory concentration (MIC) assays, we investigated the antimicrobial activity of Citrus aurantium (AEO), Citrus x limon (LEO), Eucalyptus globulus (EEO), Melaleuca alternifolia (TTO), and Cupressus sempervirens (CEO) essential oils (EOs) against three representatives of antibiotic-resistant pathogens and respective biofilms: vancomycin-resistant enterococci (

Abstract:

Discovering new antibiotics is vital to combat the growing threat of antimicrobial resistance. Most currently used antibiotics originate from the natural products of actinomycete bacteria, particularly Streptomyces species, that were discovered over 60 years ago. However, genome sequencing has revealed that most antibiotic-producing microorganisms encode many more natural products than previously thought. Biosynthesis of these natural products is tightly regulated by global and cluster situated regulators (CSRs), most of which respond to unknown environmental stimuli, and this likely explains

Abstract:

Our world of Mankind and Nature is becoming more and more seriously threatened as human populations and profligacy increase. Yet short of near-future calamity, there should be hope in global environmental education as a basis for countering such threats as those of world hunger, acidic precipitation, increasing desertification, nuclear proliferation, ‘greenhouse’ warming, and stratospheric ozone depletion. We need to educate people throughout the world to see these dangers in their global context and to act always within this perspective — be they decision-makers, legislators, or mere private

Abstract:

Medicinal plant is a major source of drug discovery for disease management. Over 85% of the population in Asia and in the Middle East use herbal medicine for disease management such as SARS caused by coronavirus. Infection from coronavirus is initiated by entry of the virus into a susceptible host cell. The two human coronaviruses of public health importance two decades ago were SARS-CoV and MERS-CoV and now SARS-CoV 2. These three viruses belong to the same class of beta coronavirus and are somewhat similar in genome sequencing, life cycle, mode of entry into a host, mode of transmission and
