Antimicrobial peptides (AMPs) represent the largest group of endogenous compounds and serves as a novel alternative to traditional antibiotics for the treatment of pathogenic microorganisms. Moricin is an important α-helical AMP plays a crucial role in insect humoral defense reactions.

In this study, we have developed a method to assess adenosine 5ʹ‐triphosphate by adsorptive extraction using surface adenosine 5'‐triphosphate‐imprinted polymer over polystyrene nanoparticles (412 ± 16 nm) for selective recognition/separation from urine.

In this study, a binary mixture in dispersive liquid-liquid microextraction was used for the preconcentration and determination of selected pesticides, pharmaceutical and hormone by GC–MS. A Box–Behnken experimental design was used to optimize the amounts of binary mixture, dispersive solvent and salt. The optimum parameters obtained were dichloromethane/1,2-dichloroethane binary mixture (200 µL), ethanol (2.0 mL) and potassium nitrate (1.0 g).

A hydroponic experiment was carried out to study the accumulation characteristics of copper (Cu) and lead (Pb) combined pollution in three ornamental plants. The results showed that these tested ornamental plants had higher tolerance to Cu–Pb combined pollution and could effectively accumulate the heavy metals. The Cu and Pb concentrations were higher in the roots of the ornamental plants than that in the shoots. For Panax notoginseng (P.

To maintain self-sufficiency in rice production and national food security, the Chinese government strongly supports research that aims at increasing the productivity of rice cultivation. Rice with genetic material from Bacillus thuringiensis (Bt rice) is transgenic rice that can reduce lepidopteran pest damage and the use of insecticides. It was developed in the 1990s and earned biosafety certificates in 2009.

Detoxification of the highly toxic cadmium element is essential for the survival of living organisms. Pseudomonas putida CadR, a MerR family transcriptional regulator, has been reported to exhibit an ultraspecific response to the cadmium ion. Our crystallographic and spectroscopic studies reveal that the extra cadmium selectivity of CadR is mediated...

Molecular imprinted polymers prepared by Pickering emulsion method with lignin as stable particle were used as dispersants in matrix solid phase dispersion, followed by ultra performance liquid chromatography‐tandem mass spectrometry analysis to research the degradation behavior of matrine in soil. The molecular imprinted polymers have regularly morphology and uniformly particles. Moreover, the adsorption experiments and the conditions of matrix solid phase dispersion were discussed.

The use of pedunculate oak (Quercus robur L.), along with other tree species, for the afforestation of heavy metal contaminated lands is an attractive prospect. Little, however, is known of Q. robur tolerance and its antioxidative system response to heavy metal exposure. The main objective of the study was to determine the cadmium-induced changes in antioxidative system of pedunculate oak in an attempt to identify molecular mechanisms underlying Cd tolerance.

In this study, ambient PM2.5 samples were collected from October 2014 to August 2015 in urban area of Luoyang (LY) and Pingdingshan (PDS), two medium-size industrial cities in central China. Sixteen priority polycyclic aromatic hydrocarbons (PAHs) were analyzed to investigate the seasonal variation, potential pollution sources, and health risk of PAHs bound to PM2.5 (PM2.5-bound PAHs).

ABSTRACT In this study, quick, easy, cheap, effective, rugged and safe combined with dispersive liquid‐liquid microextraction is developed for extraction of ten pesticides in complex sample matrices of water and milk. In this regard, effective factors of proposed extraction technique combined with gas chromatography‐flame ionization detector were designed, modeled and optimized using central composite design, multiple linear regression and Nelder‐Mead simplex optimization.
