  1. Potential genetic polymorphism of matrix metalloproteinase (MMP)-9 in Iranian migraine patients with Toxoplasma gondii infection

    • Parasitology Research
    • Toxoplasma gondii is an intracellular protozoan parasite that causes neuroinflammation in the brain and a constant need for peripheral leukocyte migration. Matrix metalloproteinase 9 (MMP-9) can play a major role in this neuroinflammation and be implicated in some neurological disorders, such as migraines. Therefore, the genetic polymorphism evaluation of MMP-9 in migraine patients with T. gondii infection was performed.

  2. Comparative Assessment of the Antibacterial and Antibiofilm Actions of Benzalkonium Chloride, Erythromycin, and L(+)-Lactic Acid against Raw Chicken Meat Campylobacter spp. Isolates

    • Antibiotics
    • Campylobacter spp. are significant zoonotic agents, which cause annually millions of human cases of foodborne gastroenteritis worldwide. Their inclusion in biofilms on abiotic surfaces seems to play a pivotal role in their survival outside of the host, growth, and spread.

  3. Upcycling Romaine lettuce outer leaves by infrared blanching and hot air drying

    • Journal of Food Science
    • Abstract Romaine lettuce outer leaves, as opposed to the more commonly marketed heart, are typically discarded and present an opportunity for upcycling as dried powders. Duquesne Romaine lettuce was evaluated to quantify and compare quality attributes of fresh outer and heart leaves, dried powders following hot air drying, and dried powders following an infrared (IR) blanching pretreatment before drying.

    • Journal of Fish Diseases
    • Abstract Vibrio harveyi is commonly found in salt and brackish water and is recognized as a serious bacterial pathogen in aquaculture worldwide. In this study, we cloned the ferric uptake regulator (fur) gene from V. harveyi wild‐type strain HA_1, which was isolated from diseased American eels (Anguilla rostrata) and has a length of 450 bp, encoding 149 amino acids. Then, a mutant strain, HA_1‐Δfur, was constructed through homologous recombination of a suicide plasmid (pCVD442).

  10. Preparation and characterization of nisin‐loaded chitosan nanoparticles functionalized with DNase I for the removal of Listeria monocytogenes biofilms

    • Journal of Food Science
    • Abstract Listeria monocytogenes biofilms represent a continuous source of contamination, leading to serious food safety concerns and economic losses. This study aims to develop novel nisin‐loaded chitosan nanoparticles (CSNPs) functionalized with DNase I and evaluate its antibiofilm activity against L. monocytogenes on food contact surfaces. Nisin‐loaded CSNPs (CS‐N) were first prepared by ionic cross‐linking, and DNase I was covalently grafted on the surface (DNase‐CS‐N).

  14. Viable Campylobacter jejuni on eggshells and its potential to cross-contaminate egg white and yolk when using a manual separation technique, determined by culture and propidium monoazide (PMA) qPCR

    • Journal of Food Protection
    • Manual separation of egg yolk from egg white using the eggshell is common practice in private households. For this, the egg is cracked and both components are separated by passing the egg yolk back and forth between the two halves of the eggshell, allowing the egg white to drip down while the egg yolk remains in the shell.

    • Journal of Separation Science
    • Although filtration is one of the most common steps in sample preparation for chemical analysis, filter membrane materials can leach contaminants and/or retain some analytes in the filtered solutions. In multiclass, multiresidue analysis of veterinary drugs, it is challenging to find one type of filter membrane that does not retain at least some of the analytes before injection in ultrahigh‐performance liquid chromatography‐tandem mass spectrometry (UHPLC‐MS/MS).
