Soil salinity is a major threat hindering the optimum growth, yield, and nutritional value of potato. The application of organic composts and micronutrients can effectively ameliorate the salinity-deleterious effects on potato growth and productivity. Herein, the combined effect of banana and soybean composts (BCo and SCo) application alongside foliar supplementation of boron (B), selenium (Se), cobalt (Co), and titanium (Ti) were investigated for improving growth, physiology, and agronomical attributes of potato plants grown in saline alluvial soil.

Aims: We investigated the effects of intraperitoneal injections of titanium dioxide nanoparticles (TiO NPs, 100 mg/kg) for 5 consecutive days on the developmental competence of murine oocytes. Furthermore, study the effects of TiO NPs on antioxidant and oxidative stress biomarkers, as well as their effects on expression of apoptotic and hypoxia inducing factor-1α (HIF1A) protein translation. Moreover, the possible ameliorating effects of intraperitoneal injections of fructose (2.

Article Synopsis
  • * Results show that 35.84% of relatives are carriers of β thalassemia, with the highest rate found in Al-Sharkia Governorate (51.32%), and 17.19% suffer from iron deficiency anemia, notably more common in Al-Gharbia Governorate (45.05%).
  • * The findings highlight the significant prevalence of β thalassemia carriers and iron deficiency anemia in the region, stressing the need for awareness and screening among close relatives of affected patients. *

Objectives: This study aims to assess the changes of lipid profile in chronic HCV patients; before, during, and after treatment with DAAs and their association with treatment response.

Methods: 301 chronic HCV patients who received SOF-based therapy were included. Serum lipid profile was assessed at different check points; baseline, 6 weeks on treatment, end of treatment (EOT) and 12 weeks after EOT; and compared between SVR and non-SVR groups.

Background: The expression of programmed cell death ligands on tumor cells has a role in the suppression of antitumor immunity, resulting in tumor immune evasion.

Objective: In this study, we evaluated the prognostic value of the soluble form of programmed death-ligand1 (sPD-L1) in Egyptian hepatocellular carcinoma (HCC) patients.

Methods: This prospective cohort study was performed between November 2016 to November 2018 on 85 individuals (25 HCC patients, 25 HCC with vascular invasion and/or extrahepatic metastasis, 25 patients with liver cirrhosis, 10 healthy controls).

Background And Aims: Hepatitis viruses are not transmitted via gastrointestinal endoscopy except if there are any mistakes in sterilization and disinfection of the endoscope that disrupt the infection control measures. So we aimed to measure the risk of transmitting HCV by GI endoscopy at department of Tropical Medicine and infectious Diseases, in a major University hospital in Egypt.

Methods: Our study was conducted on four hundred patients with exclusion of those with HCV, HBV, and/or HIV positive antibodies.

Objectives: The aim of the work was to assess the level of copeptin as a surrogate marker predicting the severity of liver diseases and its major complications.

Patients And Methods: This was a cross-sectional study that included 40 patients and 10 controls and was performed in Tanta University Hospital between June 2016 and November 2016. The studied cases were divided into five groups: group I (10 patients): compensated cirrhosis; group II (10 patients): cirrhosis with gastrointestinal hemorrhage due to portal hypertension; group III (10 patients): cirrhosis with hepatorenal syndrome; group IV (10 patients): cirrhosis with liver cell failure; and group V (10 controls): normal healthy individuals.

Background: Hepatocellular carcinoma (HCC) is a common and dangerous malignancy in many parts of the world, and especially in Egypt. Early diagnosis is the most important step in successful HCC management. However most cases are detected at late stage making effective intervention impossible.

Research is continuous for noninvasive tools for the prediction of portal hypertension than upper gastrointestinal endoscopy. Serum sCD163 correlates with hepatic venous pressure gradient, aiding in the prediction of portal hypertension. We aimed at investigating the role of sCD163 in the prediction of the presence and size of varices as well as a stratification tool for surveillance or prophylaxis by assessment of prognosis and risk of bleeding.

This study aimed at investigating the effect of progesterone on interferon signaling pathways in peripheral blood mononuclear cells (PBMCs) of patients infected with hepatitis C virus (HCV). PBMCs were isolated from peripheral blood of 38 treatment-naïve HCV-infected patients, pooled, and stimulated with progesterone in the presence and absence of its receptor antagonist, mifepristone, along with interferon alpha (IFN-α) or imiquimod. Toll-like receptor (TLR) 7 and myxovirus resistance protein A (MxA) were quantified in PBMCs using RT-qPCR.

Background: Data are scarce on ocular complications in Egyptian patients with chronic hepatitis C treated with pegylated interferon and ribavirin therapy. The aim of this study was to investigate the development of retinal lesions induced by interferon therapy for chronic hepatitis C.

Methods: We prospectively analyzed 84 patients with chronic hepatitis C (total 168 eyes), who underwent combination pegylated interferon and ribavirin therapy for 48 weeks.

Regulatory T cells (Tregs) are thought to have a critical role in the suppression of immune responses. In addition to the prevention of the development of autoimmunity, they are thought to have a role in the prevention of allergic responses to environmental allergens. Foxp3 is transcription factor (Foxp3), which is predominantly expressed by CD4+ CD25+ T cells, and may correlates with the suppressive activity of these cells.
