Background And Aims:
Hepatitis virus and alcohol are the main factors leading to liver damage. Synergy between hepatitis B virus (HBV) and alcohol in promoting liver cell damage and disease progression has been reported. However, the interaction of HBV and ethanol in hepatic steatosis development has not been fully elucidated.
Methods:
Eight-week-old male C57BL/6 mice were treated with or without HBV, ethanol, or the combination of HBV and ethanol (HBV+EtOH), followed by a three-week high-fat diet (HFD) regimen. Liver histology, serum biomarkers, and liver triglyceride levels were analysed. Furthermore, a meta-analysis of the effects of alcohol and HBV on hepatic steatosis in populations was performed.
Results:
Hepatic steatosis was significantly more severe in the HBV+EtOH group than in the other groups. The serum alanine aminotransferase, aspartate aminotransferase and liver triglyceride levels in the HBV+EtOH group were also significantly higher than those in the other groups. The HBeAg and HBsAg levels in the HBV+EtOH group were significantly higher than those in the pair-fed HBV-infected mice. In addition, the meta-analysis showed that alcohol consumption increased the risk of hepatic steatosis by 43% in HBV-infected patients (pooled risk ratio (RR)=1.43, P<0.01).
Conclusions:
Alcohol and HBV synergistically promote high-fat diet-induced hepatic steatosis in mice. In addition, alcohol consumption increases the risk of hepatic steatosis in HBV-infected patients.

Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...
