Geographical authentication of bone raw materials to determine whether they come from non-epidemic areas and natural pastoral areas is critical to quality control, food safety, and brand protection of gelatin. The establishment of an effective traceability method independent of paper records has become increasingly urgent.

ABSTRACT Background Well-tolerated, highly effective HCV treatment, known as direct-acting antivirals (DAAs), is now recommended for all people living with HCV, providing the tools for HCV elimination. We sought to understand treatment barriers among low-income HIV/HCV coinfected patients and providers with the goal of increasing uptake.

Leuconostoc mesenteroides strains isolated from kimchi were shown to be effective probiotics for inhibiting Listeria monocytogenes biofilm formation more than 40‐fold. The cell‐free supernatant from the L. mesenteroides culture also decreased Listeria biofilms. This study indicates that kimchi probiotics can be applied to repress Listeria biofilm contamination on surfaces at food processing facilities.

The aim of this work was to collect relevant input data for integration into Monte‐Carlo simulation using 10,000 iterations to obtain quantitative estimates of exposure and associated risk to Staphylococcus aureus and Salmonella. Higher prevalence rates of S. aureus (54.9 vs. 28.3%) and Salmonella (12.9 vs. 11.1%) were observed for raw milk distributed via collection milk collection centers (MCC) compared to those via dairy farms (DF). Prevalence found for S.

The present work aims to investigate the in vitro antioxidant activities of Enterobacter cloacae C3 lipopeptides, as well as the stability of sunflower oil in water (o/w) emulsion and the conservation of raw beef patties. The C3 lipopeptides were assayed for their antioxidant activity through five different tests. The C3 lipopeptides showed good in vitro antioxidant activities.

The simultaneous effects of microwave processing variables affecting the microbial quality and preservation of milk bioactive proteins were evaluated.

Reduced digestibility of foods containing oxidized proteins and the subsequent excessive accumulation of undigested components in the colon may cause changes in the intestinal flora composition. This study evaluates the characteristics of this change and the potential adverse effects on organisms. Methods and results Pork was cooked using sous‐vide or at high temperature and pressure (HTP), and freeze‐dried, resulting in different levels of oxidized damage.

Background In this study, the development of IR based‐prediction method for easy, fast and non‐destructive detection of pesticide residue levels measured by reference analysis in strawberry (Fragaria x ananassa Duch, Cv. Albion) samples using Near Infrared Spectroscopy (NIRS) and demonstrating its potential alternative or complementary use instead of traditional pesticide determination methods were aimed.

Campylobacter jejuni is the one of the leading cause of bacterial food borne gastroenteritis. PglB, a glycosyltransferase, plays a crucial role of mediating glycosylation of numerous periplasmic proteins. It catalyzes N-glycosylation at the sequon D/E-X1-N-X2-S/T in its substrate proteins. Here we report that the PglB itself is a glycoprotein which self-glycosylates at N534 site in its DYNQS sequon by its own catalytic WWDYG motif.

Abstract

Aims

Data on the variability of hyperaccumulation potential of the facultative serpentinophytes Noccaea kovatsii and N. praecox on different geological substrates are scarce. The aim of this study was to assess the accumulation potential of these two species from ultramafic and non-ultramafic substrates, with special emphasis on the hyperaccumulation of Ni, Zn and Cd.

Zearalenone (ZEN) is a mycotoxin produced by Fusarium species; however, its mechanisms of action in human livers have not been fully elucidated. Thus, we investigated the toxic mechanisms of ZEN in human liver cells. HepG2 cells were treated with ZEN (0–40 μg/mL) for up to 24 h. A significant decrease in cell viability was observed after treatment with 20 and 40 μg/mL of ZEN, including a significant increase in apoptosis and reactive oxygen species production.

Staphylococcus aureus (S. aureus) associated infections are one of the major threats to public health. The aim of the present study was to determine the antibiotic resistance pattern as well as the genetic characterization of methicillin and vancomycin resistant S. aureus (VRSA) isolated from a tertiary care hospital in Lahore. The S.

Background

Perioperative antibiotic prophylaxis in non-infected orthopedic surgery is evident, in contrast to prophylaxis during surgery for infection. Epidemiological data are lacking for this particular situation.
