Synthesis in animal cells of hepatitis B surface antigen particles carrying a receptor for polymerized human serum albumin.

Malpièce, Y; Michel, M L; Sobczak, E; Pontisso, P; Streeck, R E; Tiollais, P

A recombinant plasmid (pSVS dhfr) encoding the pre-S region and the S gene of human hepatitis B virus (HBV) and murine dihydrofolate reductase (DHFR) cDNA has been used for the transfection of Chinese hamster ovary (CHO) DHFR- cells. Selection of clones resistant to methotrexate has permitted amplif...

Ribonucleic Acid Synthesis of Vesicular Stomatitis Virus: I. Species of Ribonucleic Acid Found in Chinese Hamster Ovary Cells Infected with Plaque-forming and Defective Particles

Stampfer, Martha; Huang, Alice S.; Baltimore, David

Plaque-forming B particles of vesicular stomatitis virus (VSV) induce the synthesis of virus-specific ribonucleic acid (RNA) in Chinese hamster ovary cells, whereas defective T particles do not. Infection with low input multiplicities of B results in the formation of four species of RNA. During infe...

Ribonucleic Acid Synthesis of Vesicular Stomatitis Virus IV. Transcription by Standard Virus in the Presence of Defective Interfering Particles

Huang, Alice S.; Manders, Ernest K.

Exposure of vesicular stomatitis virus-infected Chinese hamster ovary cells to cycloheximide results in the complete transcription of virion ribonucleic acid (RNA) into only 28S and 13 to 15S viral-specific RNA species. These RNA are identical to viral messenger RNA by the following criteria: size, ...

PIV and CFD measurements of internal velocity in a forming drop in a liquid-liquid system

Timgren, Anna; Trägårdh, Gun; Trägårdh, Christian

A PIV method has been used to determine the internal motion in an oil drop during formation and to validate a numerical simulation of the drop formation process. The PIV system included a microscope attached to the camera, which gave a focal depth of 50 µm and a possibility to measure the velocity i...

Intracellular assembly and packaging of hepatitis B surface antigen particles occur in the endoplasmic reticulum.

Levinson, A D; Patzer, E J; Simonsen, C C; Nakamura, G R; Brands, R

Hepatitis B surface antigen (HBsAg) particles are secreted by Chinese hamster ovary cells that are stably transfected with the S gene of hepatitis B virus. The assembly of HBsAg into cylindrical and spherical particles occurred intracellularly within the endoplasmic reticulum. HBsAg particles accumu...

Indoor Air Pollution in China:Analysis of Global Warming Contributions and Exposure to Particles

Alnes,Line Winther Hansen

About 60% of the Chinese population lives in rural areas, where biomass and coal are the main sources of energy for cooking and heating. Indoor air pollution from household fuel burning is a major health concern, responsible for at least 420,000 premature deaths annually in China alone. However, les...

EVEN, ALSO and ONLY in Vietnamese

Hole, Daniel

The article analyzes the system of focus-sensitive particles and, to a lesser extent, clefts in Vietnamese. EVEN/ALSO/ONLY foci are discussed across syntactic categories, and Vietnamese is found to organize its system of focus-sensitive particles along three dimensions of classification: (i) EVEN vs...
