Effects of ozone treatment on the infectivity of hepatitis A virus

Autor: Deborah Strout, James M. Vaughn, James F. Novotny, Yu-Shiaw Chen

Publikováno v: Canadian Journal of Microbiology. 36:557-560

The inactivation of a large-focus-forming variant of hepatitis A virus (HM-175) by ozone was investigated. Experiments using mainly single-particle virus preparations suspended in phosphate–carbonate buffer were conducted over a range of pH levels

Inactivation of human and simian rotaviruses by chlorine dioxide

Autor: Yu-Shiaw Chen, J M Vaughn

Publikováno v: Applied and Environmental Microbiology. 56:1363-1366

The inactivation of single-particle stocks of human (type 2, Wa) and simian (SA-11) rotaviruses by chlorine dioxide was investigated. Experiments were conducted at 4 degrees C in a standard phosphate-carbonate buffer. Both virus types were rapidly in

Determination by Raman spectroscopy of the pKa of N5 of dihydrofolate bound to dihydrofolate reductase: mechanistic implications

Autor: Raymond L. Blakley, Robert Callender, Joseph Kraut, Yu-Shiaw Chen

Publikováno v: Biochemistry. 33(23)

Dihydrofolate reductase (DHFR) catalyzes the reduction of dihydrofolate (H2folate) to tetrahydrofolate by NADPH, and this requires that the pteridine ring be protonated at N5. A long-standing puzzle has been how, at physiological pH, the enzyme can p

Orientation of complex III in the yeast mitochondrial membrane: Labeling with [125I] diazobenzenesulfonate and functional studies with the decyl analogue of coenzyme Q as substrate

Autor: Anita Sidhu, Liviu Clejan, Ching-I P. Lin, Yu-Shiaw Chen, Diana S. Beattie

Publikováno v: Journal of Bioenergetics and Biomembranes. 13:357-373

Mitochondria (or mitoplasts) and submitochondrial particles from yeast were treated with [125I] diazobenzenesulfonate to label selectively proteins exposed on the outer or inner surface of the inner mitochondrial membrane. Polyacrylamide gel analysis

Inactivation of human and simian rotaviruses by ozone

Autor: Yu-Shiaw Chen, D. Morales, K. Lindburg, J M Vaughn

Publikováno v: Applied and Environmental Microbiology. 53:2218-2221

The inactivation of simian rotavirus SA-11 and human rotavirus type 2 (Wa) by ozone was compared at 4 degrees C by using single-particle virus stocks. Although the human strain was clearly more sensitive, both virus types were rapidly inactivated by

Streptococcal cell walls and synovial cell activation. Stimulation of synovial fibroblast plasminogen activator activity by monocytes treated with group A streptococcal cell wall sonicates and muramyl dipeptide

Autor: John B. Zabriskie, John A. Hamilton, Lawrence B. Lachman, Yu-Shiaw Chen

Publikováno v: The Journal of Experimental Medicine

Group A streptococcal peptidoglycan has previously been shown to be arthritogenic in rats and has been implicated as a structure present in a class of possible etiologic agents for rheumatoid arthritis. The present study reports that conditioned medi

Induction of human gamma-interferon in lymphoid cells by Staphylococcus enterotoxin B; partial purification

Autor: William E. Stewart, Marzenna Wiranowska-Stewart, Peter von Wussow, Yu-Shiaw Chen

Publikováno v: Journal of interferon research. 2(1)

Human white blood cells produced interferon (IFN) in response to Staphylococcus enterotoxin B (SEB) in vitro. The majority of this IFN was classified as IFN-gamma by virtue of its acid instability, non-neutralization by antisera recognizing alpha or
