This article describes the results of a study conducted on 71 fresh seafood samples (fish and shellfish) marketed in Zagazig city, Sharkia province, Egypt, as well as on 50 human stool samples collected at the Zagazig University Hospital. The samples were examined for the presence of Listeria monocytogenes and Escherichia coli. The investigation of L.(More)
Root vacuolar sequestration is one of the best-conserved plant strategies to cope with heavy metal toxicity. Here we report that zinc (Zn) tolerance in Arabidopsis requires the action of a novel Major Facilitator Superfamily (MFS) transporter. We show that ZIF2 (Zinc-Induced Facilitator 2) localises primarily at the tonoplast of root cortical cells and is a(More)
Oxytetracycline residues were examined in 600 samples (200 each of muscles, livers and kidneys) collected randomly from bovine carcasses slaughtered at Mansoura abattoir in Dakahlia Province, Egypt. A microbial inhibition test using Bacillus subtilis ATCC- 6633 was employed to screen the obtained samples for antibiotic residues in meat. The results showed(More)
Egypt, the single country with highest incidence of HCV infection in the world, has embarked on a government-sponsored mass treatment program using several combinations of DAAs. Recognizing the importance of extrahepatic manifestations, independently of the hepatic, a subcommittee was assigned to develop national guidelines for respective prioritizing(More)
Vasculitis is a remarkable presentation of the extrahepatic manifestations of HCV. According to the presence or absence of cryoglobulins it is subdivided into two main types: cryoglobulinemic vasculitis and non cryoglobulinemic vasculitis based on the attribution of vasculitis to serum cryoglobulins as a pathogenic factor. The attribution of(More)
Infections by H3N2-type influenza A viruses (IAV) resulted in significant numbers of hospitalization in several countries in 2014-2015, causing disease also in vaccinated individuals and, in some cases, fatal outcomes. In this study, sequence analysis of H3N2 viruses isolated in Germany from 1998 to 2015, including eleven H3N2 isolates collected early in(More)
This study investigates the retrofitted role of thymoquinone (TQ) in the Th1/Th2 paradigm imbalance in lambda-cyhalothrin (LCT) treated rats. Four groups of male Wistar rats were formed: Group I served as control. Group II received 5 mg TQ/(kg bw) daily. Group III received 0.6 mg LCT/(kg bw). Group IV was treated with TQ and LCT. All treatments were given(More)
The toxicological studies on silver nanoparticles (Ag-NPs) have become a hot topic over the past few decades due to their unique properties on the nanoscale and widespread in many commercial products that launched into the market recently. This study was undertaken to shed light on Ag-NPs toxicity on neurotransmitters with special emphasis on the impact of(More)
The genotoxic parameters are currently among the most valuable fish biomarkers for environmental risk assessment. So, the present study was directed to explore the toxic impacts of Aluminum chloride (AlCl 3) on DNA damage, apoptosis, antioxidant status and ultrastructural investigations of Nile catfish. The experiment was carried out on 48 fish that(More)
