Biochemical and electron microscopic data indicate that the human hepatitis delta viral agent contains a covalently closed circular and single-stranded RNA genome that has certain similarities with viroid-like agents from plants. The sequence of the viral genome (1,678 nucleotides) has been determined and an open reading frame within the complementary(More)
Hepatitis delta virus (HDV) is a replication-defective etiological agent of hepatitis that requires hepatitis B virus (HBV) as a helper. A complementary DNA (cDNA) fragment of the RNA genome of HDV was cloned into the plasmid vector pBR322, and the primary nucleotide sequence and predicted protein products of the cDNA fragment were determined. This cloned(More)
Synopsis of Program: TPC addresses critical issues and needs regarding the recruitment, preparation, enhancement, and retention of science, technology and mathematics (STM) teachers for grades K-12. Its goals are to improve the quality and coherence of the learning experiences that prepare and enhance STM teachers; to develop innovative resources that(More)
Several case series showed no evidence of HDV infection among cases of hepatocellular carcinoma, while others reported high levels of infection. ln two case-control studies of hepatocellular carcinoma and HDV infection among subjects seropositive for hepatitis B surface antigen, there were no anti-HD-seropositive individuals among cases or controls. Three(More)
This column has been a welcome opportunity to keep the CBE—Life Sciences Education readership aware of national efforts to improve undergraduate education in the life sciences and of ways to become a part of that effort (Woodin et al.cal Institute (HHMI), have continually maintained a dialogue with participants through formal and informal conversations,(More)
