Polycyclic aromatic hydrocarbons (PAHs) are harmful to the health of people and other organisms due to their high toxicity, difficult degradation, and wide distribution. At present, the removal of PAHs from the environment is still an urgent challenge. In this study, silica-coated magnetic nanoparticles were conjugated with DNA and then used to remove 1, 2-benzoanthracene (BaA) from aqueous solution due to the intercalation between BaA and DNA.

Journal of Food Processing and Preservation, Accepted Article. The effect of microwave power levels, frying time and temperature on mass transfer and acrylamide formation during deep-fat frying of carrot slices were determined. Maximum and minimum moisture loss were measured respectively in the control (fried at 170°C for four minutes) and samples pretreated with microwave at 7W/g power and fried at 150°C for two minutes.

Journal of Applied Microbiology, Accepted Article. To characterize the genetic relatedness, phenotypic and genotypic antimicrobial resistance and plasmid content of 80 S. Infantis strains isolated from food, humans and veterinary sources from 2013 to 2018 in Brazil.

This study aimed to investigate the prevalence of fosfomycin fosA7 in Salmonella enterica isolates from food animals and retail meat products in China and the impact of fosA7 on bacterial fitness. A total of 360 Salmonella isolates collected from 11 provinces and cities in China were detected for fosA7. All fosA7-positive Salmonella isolates were determined minimum inhibitory concentrations (MICs) and sequenced by Illumina Hiseq. The fosA7 gene of S. Derby isolate HA2-WA5 was knocked out.

Author(s): Barun Yadav, M.S. Roopesh Salmonella, a foodborne pathogen, has been frequently associated with recalls of fresh food products, including poultry meat products. Atmospheric cold plasma (ACP) is a novel non-thermal technology, which has potential to reduce pathogens in food products.

This review (with 126 references) aims at providing an updated overview of the recent developments and innovations of the preparation and application of magnetic nanoparticles for food safety analysis. During the past two decades, various magnetic nanoparticles with different sizes, shapes, and surface modifications have been designed, synthesized, and characterized with the prospering development of material science.

Fusarium verticillioides is pathogenic to maize and mycotoxin-producer, causing yield losses, feed and food contamination, and risks to human and animal health. Endophytic (ISD04 and IPR45) and epiphytic (CT02 and IM14) bacteria from maize silks were tested in vitro and greenhouse against F. verticillioides and for hydrolytic enzyme production (cellulase, pectinase, protease, lipase, and chitinase).

Fish gut microbiota, encompassing a colossal reserve of microbes represents a dynamic ecosystem, influenced by a myriad of environmental and host factors. The current study presents a comprehensive insight into Sardinella longiceps gut microbiome using whole metagenome shotgun sequencing. Taxonomic profiling identified the predominance of phylum Proteobacteria, comprising of Photobacterium, Vibrio and Shewanella sp.

It is well-established that botulinum toxin (BT) injections improve quality of life in patients with postparalytic hemifacial spasm. Nevertheless, injection-related pain and contracture-related pain have not yet been studied. The primary objective of our study was to evaluate injection-related pain in patients with facial palsy sequelae, and to compare the standard technique (syringe) with the Juvapen device.

Botulism is a rare, sometimes fatal paralytic illness caused by botulinum neurotoxins. BAT® (Botulism Antitoxin Heptavalent (A, B, C, D, E, F, G)—(Equine)) is an equine-derived heptavalent botulinum antitoxin indicated for the treatment of symptomatic botulism in adult and pediatric patients.

Cancer subtype classification helps us to understand the pathogenesis of cancer and develop new cancer drugs, treatment from which patients would benefit most. Most previous studies detect cancer subtypes by extracting features from individual samples, ignoring their associations with others. We believe that the interactions of cancer samples can help identify cancer subtypes.

Introduction: Sepsis is a serious and expensive healthcare problem, when caused by a multidrug-resistant (MDR) bacteria mortality and costs increase. A reduction in the time until the start of treatment improves clinical results. The objective is to perform a systematic review of economic evaluations to analyze the cost-effectiveness of diagnostic methods in sepsis and to draw lessons on the methods used to incorporate antimicrobial resistance (AMR) in these studies.

Worldwide, enterotoxigenic Escherichia coli (ETEC) cause neonatal diarrhea and high mortality rates in newborn calves, leading to great economic losses. In Bavaria, Germany, no recent facts are available regarding the prevalence of virulence factors or antimicrobial resistance of ETEC in calves. Antimicrobial susceptibility of 8713 E. coli isolates obtained from 7358 samples of diseased or deceased diarrheic calves were investigated between 2015 to 2019.

Antimicrobial resistance (AMR) data from humans are mostly collected from clinical isolates, whereas from livestock data also exist from colonizing pathogens. In Germany, livestock data are collected from clinical and nonclinical isolates. We compared resistance levels of clinical and nonclinical isolates of Escherichia coli from weaning and fattening pigs with clinical outpatient isolates of humans from urban and rural areas.

Journal of Food Science, EarlyView. To estimate human exposure to Salmonella enterica, it is essential to understand the pathogen distribution and characteristics. Prevalence and concentration of S. enterica were determined in mango, tomato, and raw chicken samples purchased in three states (Aguascalientes, Querétaro, and Guadalajara) located in the central region of Mexico during two seasons. In addition, S.

Journal of Food Safety, EarlyView. Squid ink is rich in abundant natural proteins, lipids, and minerals. The aim of this study was to investigate the influences of different types and contents of modified starch with different processes on the stability and fluidity of squid ink sauces.

Journal of Separation Science, Accepted Article. A new green miniaturized quick, easy, cheap, effective, rugged, and safe approach was developed and used for the extraction of multiclass 16 pesticides in milk before GC analysis. The miniaturization of method reduced the consumption of chemical reagents and samples. Magnetic three-dimensional graphene was used as sorbent in the clean-up step. Choline chloride:lactic acid (1:2) natural deep eutectic solvent was used as desorption solvent.

The microbial dextran (MD) as a natural bacterial hydrocolloid was used for acrylamide (AA) inhibition in gluten-free quinoa biscuits. The European council approved the use of MD as a safe functional additive in bakery products. AA was spontaneously produced during the baking of 100% quinoa biscuit dough which was quantified at 2142 ± 3 μg kg−1dry biscuit.

Comprehensive Reviews in Food Science and Food Safety, EarlyView. Tetrodotoxins (TTXs) are a group of potent neurotoxins named after the Tetraodontidae fish family (pufferfish). TTXs have been reported in several animal taxa, both terrestrial and marine. The ingestion of TTX-contaminated flesh can cause serious neurotoxic symptomatology and can eventually lead to death. Traditionally, TTXs have been associated with Asian countries, in particular with pufferfish consumption.
