Quantitative Risk Assessments of Hepatitis A Virus and Hepatitis E Virus from Raw Oyster Consumption.

A quantitative risk assessment of hepatitis A virus (HAV) and hepatitis E virus (HEV) from raw oyster consumption from farm and retail was evaluated over three seasons. This risk assessment comprises four steps: hazard identification, dose-response assessment, exposure assessment, and risk characterization. We used probabilistic models for prevalence, concentration, and oyster consumption.

BCAP 31 expression and promoter demethylation in psoriasis.

Background: Psoriasis is the disease of abnormal keratinocyte differentiation and apoptosis. Alterations in DNA methylation leading to keratinocyte hyperproliferation is one of the proposed pathogenic mechanisms of psoriasis. B-cell receptor associated protein (BCAP31) has been reported to be involved in the proliferation and apoptosis of keratinocytes.
