Proteolysis is a fundamental property of all living cells. In the bacterium Salmonella enterica serovar Typhimurium (S. Typhimurium), the HspQ protein controls the specificities of the Lon and ClpAP proteases. Upon acetylation, HspQ stops being a Lon substrate and no longer enhances proteolysis of the Lon substrate Hha.

Polycyclic aromatic hydrocarbons and polycyclic aromatic nitrogen heterocycles are believed to be widespread in different areas of the interstellar medium. However, the astronomical detection of specific aromatic molecules is extremely challenging. As a result, only a few aromatic molecules have been identified, and very little is known about how they...

Emerging and fugitive contaminants (EFCs) can be introduced into the food chain through plants, particularly crop plants, and have threatened food safety and human health. The method for determination of volatile EFCs in plant tissues remains challenging.

A cold-induced-homogeneous liquid–liquid extraction method combined with deep eutectic solvent-based dispersive liquid–liquid microextraction has been done to extract several endocrine disrupting compounds (phenol, p-chlorophenol, p-nitrophenol, octylphenol, methyl paraben, ethyl paraben, butyl paraben, and bisphenol A) and hydroxymethylfurfural from honey samples before their determination by gas chromatography–mass spectrometry.

This study aimed to produce wheat flour and poly (butylene co-terephthalate adipate) films with the addition of free and microencapsulated oregano essential oil by blown extrusion and to evaluate its applicability as an active packaging in the preservation of the Brazilian fresh pastry, known as Pastel. The oregano essential oil microparticles were produced by spray drying and characterized in terms of morphology, encapsulation efficiency, and mean diameter.

Multidrug-resistant Acinetobacter baumannii (A. baumannii) causes severe and often fatal healthcare-associated infections due partly to antibiotic resistance. There are no studies on A. baumannii lipidomics of susceptible and resistant strains grown at lethal and sublethal concentrations. Therefore, we analyzed the impact of colistin resistance on glycerolipids’ content by using untargeted lipidomics on clinical isolate.

Transboundary and Emerging Diseases, Accepted Article. Since 2014, highly pathogenic avian influenza H5N6 viruses have been responsible for outbreaks in poultry. In this study, four H5N6 virus strains were isolated from fecal samples of sick white ducks and dead chickens in Shandong in 2019. These H5N6 viruses were triple‐reassortant viruses that have not been previously characterized. Their HA genes were derived from the H5 viruses and were closely related to the vaccine strain Re‐11.

Zoonoses and Public Health, EarlyView. The current study is undertaken to characterize the prevalence, genotypes distribution, antibiotic resistance and genetic diversity of Clostridium perfringens (C. perfringens) collected from different stages of a chicken production chain.

Zoonoses and Public Health, EarlyView. In humans, hepatitis E virus (HEV) is responsible for an acute enterically transmitted hepatitis, which can become chronic in immune‐compromised patients. Genotypes 3 and 4 (HEV‐3 and HEV‐4) are zoonotic, and domestic pigs and wild boar are the main reservoirs.

Journal of Food Science, EarlyView. Salmonella, being one of the most widespread foodborne pathogens, is a compulsory test item required by national food safety standard of China and many other countries. More sensitive and specific Salmonella detection method is still needed since traditional methods are time consuming and highly dependent on enormous manpower and material resources.

Journal of Food Science, EarlyView. In this work, the occurrence of 34 common antibiotic (15 sulfonamides and 19 quinolones) residues were evaluated in 236 ready‐to‐eat duck eggs (salted and preserved duck eggs) marketed through e‐commerce stores by ultra‐performance liquid chromatography coupled to tandem mass spectrometry, and subsequent dietary risk assessments for Chinese consumers were conducted.

Journal of Food Science, EarlyView. The aim of the present study was to design a delivery system of curcumin (CU) loaded solid lipid nanoparticles (CU‐CSLNs) for evaluating the antimicrobial properties in hamburger patty. Solid lipid nanoparticle (SLN) was prepared through a homogenizing technique.

Journal of Food Science, EarlyView. Acrylamide (AA), which is a carcinogen in humans, has been a research focus in terms of food risk assessment. However, few published studies have explored protein strategies to reduce the health risks of AA. The objective of this study was to investigate the binding of AA with soy protein isolate (SPI) and elucidate the binding mechanism.

Journal of Food Safety, EarlyView. The aim of this study was to develop a portable electronic nose (e‐nose) system for the rapid and convenient detection of saponin in submerged fermentation of Tremella aurantialba (T. aurantialba) in situ. The system was built using hardware and software systems. The hardware system consisted of a gas path module and a circuit module, and the software framework provided a friendly human–computer interface and multivariate computational tools.

Journal of Food Safety, EarlyView. This paper aims to create a new hybrid ensemble data mining model to predict the Salmonella presence in agricultural surface waters based on the combination of heterogeneous ensemble approach for feature selection, clustering, regression, and classification algorithms. The data set for this study was collected from six agricultural ponds in Central Florida consisting of 23 features with 540 instances (26 Salmonella positive and 514 Salmonella negative).

Journal of Food Safety, EarlyView. This article presents the release kinetics (RK) of a fungicidal antimicrobial agent (AMA), potassium sorbate (PS), that prolongs the shelf life of packaged food. The effects of PS release are explored on peanut and fresh bread to determine the effects of PS on Aspergillus niger (AN) microbe growth. The AN was cultured in a potato dextrose agar (PDA) medium to obtain AMA activity on the film.

Journal of Food Processing and Preservation, Accepted Article. In the present study, an electronic tongue (e‐tongue) system based on cyclic voltammetry (CV) with three electrodes (pencil graphite (PG), screen printed (SP), and glassy carbon (GC)) was fabricated to investigate and detect heavy metals, such as cadmium (Cd), lead (Pb), tin (Sn), and nickel (Ni) (at three concentrations of 0.05, 0.1, and 0.25ppm) in sunflower edible oil.

Journal of Food Processing and Preservation, Accepted Article. Heavy metal pollution in water negatively affects the health status of fishes and makes it toxic to human health. Conventional chemical‐based methods for fish quality assessment are destructive, highly time‐consuming, and require expensive machines and expert manpower.
