BACKGROUND Hepatitis B virus (HBV) infection is the most common and serious liver infection in the world. An estimated 350 million people are chronic carriers of this virus, of whom, more than 620,000 die from liver-related diseases annually. Due to the vaccination program, prevalence of HBV, particularly among the younger generation, is reported to have declined in recent years in Iran. OBJE...

Conceptual hydrologic models are useful tools as they provide an interpretable representation of the hydrologic behaviour of a catchment. Their representation of catchment’s hydrological processes and physical characteristics, however, implies simplification of the complexity and heterogeneity of reality. As a result, those models often 5 show a lack of flexibility in reproducing the vast spect...

Representation of the hydrological interaction between the land surface and the atmosphere requires considerable improvement, particularly for predicting evapotranspiration feedbacks for use in models of the general circulation (GCMs) of the atmosphere. The predictive model developed here attempts to use a water balance approach that extracts information from the masses of catchment-scale time ...

Ant colony optimization algorithms (ACOs) have been basically introduced to discrete variable problems and applied to different research domains in several engineering fields. Meanwhile, abundant studies have been already involved to adapt different ant models to continuous search spaces. Assessments indicate competitive performance of ACOs on discrete or continuous domains. Therefore, as poten...

Abstract Land-use changes often have significant impact on the water cycle, including changing groundwater/surface-water interactions, modifying groundwater recharge zones, and increasing risk of contamination. Surface runoff in particular is significantly impacted by land cover. As surface can act as a carrier for contaminants found at surface, it important to characterize dynamics anthropogen...

Aims: Healthy gut microbiome plays a crucial role in the treatment of Hepatitis B Virus (HBV) infection and chronic liver disease. Based on existing studies, we aimed to explore difference efficacy Fecal Microbiota Transplantation (FMT) patients with different stages HBV-related Methods: In this study, 10 HBV HBeAg-negative infection, 8 Chronic (CHB) hepatitis cirrhosis Child-Pugh score A, 9 B/...

background: hepatitis b infection is a major public health problem worldwide. dental students who are frequently in contact with body fluids like blood and saliva are still at high risk for hbv exposure. the aim of this study was to evaluate the effectiveness of hbv vaccine and personal factors associated with serologic evidence of the immune response. methods: a descriptive-cross sectional stu...

Mathematical modeling is a vast field that has interdisciplinary implications for research. These models help to investigate the basic dynamics and quantitative behavior of infectious diseases affect human beings, such as COVID-19, hepatitis B virus (HBV), immunodeficiency (HIV). The current study investigates spread HBV by using model. In order determine stability disease-free endemic equilibr...
