Abstract
This study aimed to purify human chorionic gonadotropin (HCG) from the urine of pregnant women with high biological activity (10811 IU/mg) and purity (98.2%), by simple capturing of HCG using DEAE Sepharose FF and polishing using Sephacryl S200 HR. The HCG obtained was characterized by SDS-PAGE and dissociated into alpha and beta subunits using the urea treatment method. The βHCG subunits were injected into rabbits for the production of highly specific polyclonal anti-βHCG antisera. The polyclonal anti-βHCG was locally produced in rabbits and assessed for binding titer (1/10000), displacement (84.8%), and specificity (98.8%). Purified HCG along with locally prepared polyclonal anti-βHCG antisera were used as basic components of the in-house Radioimmunoassay system for quantitative estimation of HCG in human serum.

Abstract
Hepatitis C virus (HCV) infection in Egypt is the most serious health problem. Identifying HCV-positive persons at high risk of early complications can help prioritize treatment decisions. Recently, attention has been directed to non-invasive, accurate alternatives using serum biochemical markers. The transforming growth factor β 1/interleukins pathway plays an important role in the process of cell injury and inflammation. Thus, TGF-β1 and IL-17 were assessed in serum of chronic HCV patients with correlation to hepatic inflammatory and fibrotic status. The quantitative serum levels of TGF-β1 and IL-17 were analyzed among chronic hepatitis C (CHC) patients (n=75) and normal control (NC) subjects (n=15). Disease severity in patients was assessed using the Child-Pugh scores and METAVIR. Serum levels of TGF-β1 and IL-17 were significantly increased in HCV patients compared to control group. Furthermore, the levels of TGF-β1 and Il-17 were positively correlated to serum transaminases and alpha-fetoprotein and they were negatively correlated with serum albumin and platelets. Additionally, the serum levels of TGF-β1 and Il-17 were associated with inflammation grades and stages of liver fibrosis. TGF-β1 and IL-17 may be hopeful serum biomarkers concerned in the progression of liver inflammation and fibrosis accompanying chronic HCV infection. Therefore, they could be used in the future as targets for anti-fibrotic therapy of chronic HCV to ameliorate the disease progress.

Abstract
Candida is the most frequent common causes of invasive fungal infections and associated with high morbidity and mortality. Most of available antifungal agents have side effects. This opened up new avenues to investigate the antifungal efficacy of active extracts from marine algae. So the aim of this study was to evaluate the protective and the curative effect of Ulva fasciata extract against an invasive candidiasis in mice and to study its underlying mechanism. The active ingredients of Ulva fasciata extract were evaluated using HPLC and GC/MS. Fifty mice were included in current work, and the level of inflammatory markers; Interleukin (IL)-4, IL-12, Interferon-gamma (IFN-γ) and Tumor necrosis factor-alpha (TNF-α) were determined using ELISA kits. Hematological, biochemical and oxidative stress parameters were determined using commercial kits. Moreover, the histopathological examinations were carried on liver, kidney and spleen for all groups. The results obtained showed that treatment with U. fasciata either before or after Candida infection significantly improved the hematological, biochemical alterations and antioxidant status caused by this infection. Furthermore, the U. fasciata reduced histopathological changes induced by Candida as well as it could increase the expression of IL-12 and IFN-γ while minimized the expression of TNF-α and IL-4 in all infected mice compared to infected untreated mice. These data propose that U. fasciata can ameliorate inflammatory reactions related to Candida albicans cytotoxicity via its ability to augment cellular antioxidant defenses by its active compounds.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common cancer types with a high prevalence and itis the leading cause of cancer deaths worldwide. This study aimed to investigate the antiproliferative effect of aqueous and ethanol extracts of Origanum majorana leaf on human hepatocellular carcinoma (HepG2) cell line through incubation of various concentrations of origanum majorana extracts with HepG2 and at different time intervals. The effects of aqueous and ethanol extracts of O. majorana L. on HepG2 cell viability, nuclear factor kappa B (NF-kB) gene expression were examined. The results of the cell viability assays showed that aqueous and ethanol extracts exhibited a highly significant inhibitory effect on HepG2 cell proliferation which was evidenced by a reduction in viable cell count. The results were confirmed by microscopical examination of cell morphology. Furthermore, the O. majorana L. extracts suppressed the activity of NF-kB gene expression of HepG2 cells compared to the control.The conclusions from this study suggest that marjoram extracts exhibit anti-proliferative effect against HCC through suppressing the activity of NF-kB gene expression and high antioxidant activity.
