Abstract

Background

The current meta-analysis study was aimed to estimate the potentially toxic elements (PTEs) contamination in cereal grains and their products such as wheat, rice, corn, maize, barley, oat, peas, soybean, cornflakes, and breakfast.

We have reviewed a paper titled “Bioaccumulation of Methyl Siloxanes in Common Carp (Cyprinus carpio) and in an Estuarine Food Web in Northeastern China” by Xue et al., which was published in the Archives of Environmental Contamination and Toxicology in 2019.

Graphical overview of the incidence and characterization of Aspergillus section Flavi in raw materials and finished feed in Algeria and their ability to produce aflatoxins, cyclopyazonic acid and ochratoxine A. Abstract In Algeria, little information is available on the population structure of Aspergillus section Flavi in raw materials and resultant animal feeds.

Sand filter‐UV‐C treatment for irrigation water. Abstract Surface irrigation water is a food safety risk due to susceptibility to contamination and varying turbidity that affects chlorination efficacy. Effectiveness of a combined high‐throughput, commercially available sand filter and UV‐C system to inactivate Escherichia coli (K12, and attenuated O157:H7) in simulated irrigation water of varying turbidity and actual irrigation water was investigated.

The AOAC 2007.1 Quick, Easy, Cheap, Effective, Rugged and Safe official method, together with gas chromatography coupled to a triple quadrupole mass spectrometer was applied for the analysis of 38 multiclass pesticides from dried fruits typically cultivated and exported from Colombia: uchuva (Physalis peruviana), lulo (Solanum quitoense), guanabana (Anona muricata) and pitahaya (Hylocereus undatus).

Beauverolides (beauveriolides) are abundant biologically active cyclodepsipeptides produced by many entomopathogenic fungi, including those that are used as biopesticides. Beauverolides act as cholesterol acyltransferase inhibitors in humans; thus, their mode of action has been the subject of pharmacological and clinical research. The cost‐effective analytical methods are needed for fast, routine laboratory analysis of beauverolides.

Bovine serum albumin imprinted magnetic microspheres, with functional monomers of modified chitosan, N‐isopropylacrylamide and sulfobetaine methacrylate, were successfully prepared and characterized in detail. Computational analyses showed that during the preparation process, modified chitosan can effortlessly form multiple non‐covalent bonds with protein molecules. Temperature‐sensitive N‐isopropylacrylamide improves the elution efficiency by abating the mass transfer resistance.

Aminopeptidase N is an important metalloenzyme from the M1 zinc metallopeptidase family, which is present in numerous apicomplexan parasites, including Plasmodium, Eimeria, and Cryptosporidium. Aminopeptidase N is a potential drug target, and hence, its properties have been widely investigated. In the current study, the cellular localization and enzyme characteristics of Toxoplasma gondii aminopeptidase N3 (TgAPN3) were evaluated in vitro.

Effects of zinc (Zn) and lead (Pb) exposure on oxidative biomarkers and heat shock protein (HSP) expression, and their possible relation to ovarian steroidogenesis in fish were investigated. Female Cirrhinus cirrhosus were exposed to 1/10th of LC50 of metals for 30 days, and kept for another 30 days without metal exposure.

Background Influenza viruses must utilize host factors to complete their lifecycle. Species-specific differences in host factors between birds and mammals mean that avian influenza viruses (AIVs) replicate well in avian hosts but not in human hosts. Acidic nuclear phosphoprotein 32 family member A (ANP32A) has been identified as the host restriction factor for the viral polymerase (vPol) activity of AIVs.

Human noroviruses (HuNoVs) are among the main pathogens causing acute nonbacterial gastroenteritis. Histo-blood group antigens (HBGAs) are widely accepted receptors for HuNoV specific binding. HBGA-like substances in produce are also considered as the critical ligands for capture of HuNoVs. However, the composition of viral ligands from food substrates remains unknown.

Various signaling pathways in filamentous fungi help cells receive and respond to environmental information. Previous studies have shown that the mitogen-activated protein kinase (MAPK) pathway is phosphorylation-dependent and activated by different kinase proteins. Serine/threonine kinase plays a very important role in the MAPK pathway. In this study, we selected the serine/threonine kinase AflSte20 in Aspergillus flavus for functional study.

Short chain fatty acids (SCFAs) are commonly produced by healthy gut microbiota and they have a protective role against enteric pathogens. SCFAs also have direct antimicrobial activity against bacterial pathogens by diffusion across the bacterial membrane and reduction of intracellular pH. Due to this antimicrobial activity, SCFAs have promising applications in human health and food safety.

The emergence of blaKPC-2 and blaNDM-1 producing Klebsiella pneumoniae represents a great problem in many Egyptian hospitals. One hundred and twenty-six K. pneumoniae isolates from patients admitted to Assiut University Hospital were identified by an API20E kit. Carbapenemase-producing K. pneumoniae (CPKP) was detected by the modified carbapenem inactivation method (mCIM), the EDTA-modified carbapenem inactivation method (eCIM), and an E-test.
