✦ Synopsis

Abstract

The effects of 11 different protease inhibitors on mating reactivity and pair formation in the conjugation process of the ciliated protozoan Paramecium caudatum were investigated. Of the 11 inhibitors tested, six microbial and three synthetic inhibitors showed no effect on either pair formation or mating reactivity even at their highest concentrations. Soybean trypsin inhibitor and ovomucoid also showed no effect on pair formation even though they temporarily repressed mating reactivity. These results indicate that the process of pair formation during the conjugation process does not involve an extracellular proteolytic reaction.

We have studied an indirect role of serine and thiol proteases in the activation of human neutrophils in vitro. Stimulation was evaluated using a chemiluminescence (CL) generation system. Receptor-dependent and receptor-independent stimuli were studied, e.g. opsonized zymosan, formyl-methionyl-leucy

## Abstract The effect of obesity induced by a high‐fat diet on the pharmacokinetics (PK) of nelfinavir (NFV) was investigated, focusing on the change of distribution and elimination caused by dyslipidemia and hepatic steatosis. The plasma unbound fraction (__f__~u~) of NFV in obese rats (0.61±0.0
