Glycyrrhizin inhibits human parainfluenza virus type 2 replication by the inhibition of genome RNA, mRNA and protein syntheses.

The effect of glycyrrhizin on the replication of human parainfluenza virus type 2 (hPIV-2) was examined. Cell fusion induced by hPIV-2 was inhibited by glycyrrhizin, and glycyrrhizin reduced the number of viruses released from the cells. Glycyrrhizin did not change cell morphology at 1 day of culture, but caused some damage at 4 days, as determined by the effect on actin microfilaments.

Flexibility of the transverse arch of the forefoot.

Purpose: To measure the percentage of the transverse arch length (%TAL) in 2 positions using a 3-dimensional motion capture system to determine the flexibility of the transverse arch of the forefoot.

Methods: 19 men and 10 women with no lower extremity injury or deformity were included. The %TAL of the left foot was measured using a digital caliper in the standing position and the lower leg maximum anterior tilting (LMAT) position.

Legume lectins inhibit human parainfluenza virus type 2 infection by interfering with the entry.

Three lectins with different sugar binding specificities were investigated for anti-viral activity against human parainfluenza virus type 2 (hPIV-2). The lectins, concanavalin A (Con A), lens culinaris agglutinin (LCA) and peanut agglutinin (PNA), inhibited cell fusion and hemadsorption induced by hPIV-2. Virus nucleoprotein (NP) gene synthesis was largely inhibited, but fusion (F) and hemagglutinin-neuraminidase (HN) gene syntheses were not.

Method of duplicating film using the CR system: evaluation of detectability in a simulated nodule.

Purpose: Since film processors used for screen-film systems have been decreasing recently, it is becoming difficult to develop duplicating film (Dup film) used conventionally. The purpose of this study was to evaluate the usefulness of the method of duplicating film using a computed radiography (CR) system.

Materials And Methods: The process of duplicating film using CR is 1) to eliminate energy accumulated on the imaging plate (IP) using white light, 2) to accumulate energy on the whole surface, and 3) to place the original film in piles.
