Silver is a potent antimicrobial agent against variety of microorganisms and once the element has entered bacterial cell, it accumulates as silver nanoparticles with large surface area causing cell death. At same time, becomes reservoir for silver. This study aims to test microcidal effect silver-killed E. coli O104: H4 its supernatant fresh viable cells bacterium some other species, including O157: H7, Multidrug Resistant (MDR) Pseudomonas aeruginosa Methicillin Staphylococcus aureus...

HEV is the most causative agent of acute viral hepatitis globally. causes acute, chronic, and extrahepatic manifestations. Chronic infection develops in immunocompromised patients such as organ transplant patients, HIV-infected leukemic patients. The source chronic not known. Also, manifestations associated with still unclear. Hepatotropic viruses HCV HBV replicate peripheral blood mononuclear cells (PBMCs) these become a reactivation infections allograft Herein, we reported that PBMCs bone...

Ventilator-associated pneumonia caused by Pseudomonas aeruginosa (P. aeruginosa) is a major health-care problem. In this study, we explored the epidemiology of virulence determinants among multi-drug-resistant (MDR) clinical P. isolates from hospitalized patients with ventilator-associated in intensive care units Upper Egypt.MDR were screened for presence eight factors and typed ERIC-PCR.A total 39 MDR selected out 173 isolated showing combination adhesion cytotoxicity patterns, detection...

Renal disorders are associated with Hepatitis E virus (HEV) infection. Progression to end-stage renal disease and acute kidney injury complications HEV The mechanisms by which mediates the glomerular diseases remain unclear. CD10+/CD13+ primary proximal tubular (PT) epithelial cells, isolated from healthy donors, were infected HEV. Inflammatory markers assessed in presence or absence of peripheral blood mononuclear cells (PBMCs) same donors. replicated efficiently PT as shown increase load...

HEV-Ag ELISA assay is a reliable diagnostic test in resource-limited areas. HEV genotype 1 (HEV-1) infections are either self-limited or progress to fulminant hepatic failure (FHF) and death if anti-HEV therapy delayed. Limited data available about the utility of Ag on HEV-1 infections. Herein wWe aimed study kinetics during at different stages, i.e., acute infection, recovery, progression FHF. Also, we evaluated this marker predict outcomes Plasma hepatitis E (AHE) patients were assessed...

Viral infections trigger inflammation by controlling ATP release. CD39 ectoenzymes hydrolyze ATP/ADP to AMP, which is converted CD73 into anti-inflammatory adenosine (ADO). ADO an and immunosuppressant molecule can enhance viral persistence severity. The CD39-CD73-adenosine axis contributes the immunosuppressive T-reg microenvironment may affect COVID-19 disease progression. Here, we investigated link between expression, mostly on T-regs, levels of CD73, adenosine, receptors with severity...

Viruses can trigger glomerulonephritis (GN) development. Hepatitis viruses, especially C virus and B are examples of the viruses that GN initiation or progression. However, proof a correlation between E infection is not clear. Some studies confirmed development during acute chronic HEV infections, mainly caused by genotype 3. While others reported there no relation exposure A recent study showed reduced glomerular filtration rate was developed in 16% 1 (HEV-1) infections returned to normal...

Pseudomonas aeruginosa is an opportunistic pathogen that can cause a variety of diseases especially in the hospital environment. However, this also exhibits antimicrobial activity against Gram-positive bacteria and fungi. This study aimed to characterize different virulence factors, secreted metabolites their role suppression Candida growth. Fifteen P . isolates were tested for anticandidal 3 spp. by cross-streak method. The effect on hyphae production was microscopically using light...

Background: The increased rate of resistance among Gram-negative bacteria to 𝛽-lactam, quinolone, or aminoglycoside antibiotics has resulted in use colistin antibiotic with the unavoidable risk emerging and spreading resistant strains. Objectives: Our study aimed investigate urinary tract infections for detection E. coli strains causing isolated from two University hospitals Upper Egypt; Assiut Minia hospitals. Methodology: One hundred isolates were collected urine specimens at both...

Background: Helicobacter pylori (H. pylori) is a common cause of gastric ulcers and risk factor for carcinoma. Little data are available about the characters H. causing infections in patients from Upper Egypt. Therefore, aim this study was to investigate frequency infection Egyptian undergoing endoscopy complaining persistent upper gastrointestinal symptoms directly biopsy specimens using PCR technique associated virulence-related genes positive samples.

In this essay, I argue that the concept of queerness, defined as resisting static productions knowledge and being, constitutes a threat to monolithic narrative Zionist Diasporic memory. As Jewish memories were forced into one homogeneous linear narrative, Israeli identity was whitewashed branded; it differentiated itself from Arabness Mizrahi Jews, served suppress histories migrants Palestinians alike in favor absolute sovereignty settler colonialism. This process, which call de-queering...
