TL;DR: It is shown that Sox9 is expressed throughout the biliary and pancreatic ductal epithelia, which are connected to the intestinal stem-cell zone, which suggests interdependence between the structure and homeostasis of endodermal organs, with Sox9 expression being linked to progenitor status.
Journal ArticleDOI
Antibody to hepatitis B core antigen as a screening test for occult hepatitis B virus infection in Egyptian chronic hepatitis C patients.

TL;DR: A significant number of patients with anti-HBc had detectable levels of HBV-DNA in the serum, and Egyptian chronic HCV patients have a high prevalence of occult HBV infection.
Journal ArticleDOI
Occult hepatitis B virus infection in Egypt.
Ashraf Elbahrawy,Alshimaa Alaboudy,Walid El Moghazy,Ahmed Elwassief,Ahmed Alashker,Abdallah Mahmoud Abdallah +5 more
TL;DR: The available data suggested that screening for OBI must be a routine practice in these groups of patients, and further studies needed for better understand of the epidemiology of OBI among Egyptian young generations after the era of hepatitis B vaccination.
Journal ArticleDOI
High false-negative rate of anti-HCV among Egyptian patients on regular hemodialysis.
Assem El-Sherif,Ashraf Elbahrawy,Atef Aboelfotoh,Magdy Abdelkarim,Abdel-Gawad Saied Mohammad,Abdallah Mahmoud Abdallah,Sadek Mostafa,Amr Elmestikawy,Ahmed Elwassief,Mohamed Salah,Mohamed Ali Abdelbaseer,Kouka Saad El-Din Abdel-Wahab +11 more
TL;DR: The high false‐negative rate of anti‐HCV among HD patients in this study justifies testing of a large scale of patients for precious assessment of effectiveness of nucleic acid amplification technology testing in screening HD patient.
Journal ArticleDOI
Conventional Narrow-Band Imaging Has Good Correlation with Histopathological Severity of Helicobacter pylori Gastritis
TL;DR: Five different histopathological grades of HP gastritis, in terms of grade of gastric atrophy, intestinal metaplasia, infiltration by inflammatory cells, and density of HP infection, were recognized among the different C-NBI mucosal patterns.
