The second-orderrate constants for inactivation of acetylcholinesterase,-chymotrypsin, and
trypsin by a series of sulfonyl fluorides havebeen determined. These compounds are most …

Phenylmethanesulfonyl fluoride reacts stoichiometrically with a-chymotrypsin, producing an
inactive monosulfonyl enzyme and one equivalent of free acid. Titration of the enzyme with …

Background. Rapid urine tests for infection (urinalysis, dipstick) have low up-front costs.
However, many false positives occur, with important downstream consequences, including …

S-Aminoethylcysteine is also obtained when 1-dimethylaminonaphthalene-5-sulfonyl
chymotrypsin is treated as described. This indicates that the corresponding sulfonyl chloride …

Objectives Our primary objective was to assess the accuracy of Doppler ultrasound versus
manual palpation in detecting any pulse with an arterial line waveform in cardiac arrest. …

The L1 larvae of the parasitic nematode Trichinella spiralis invade skeletal muscle and initiate
a process that has been interpreted to represent skeletal muscle dedifferentiation. In this …

Publisher Summary This chapter describes the mechanism of sulfonylation with sulfonyl
halides. Sulfonyl halides react with many of the serine esterases such as chymotrypsin, trypsin, …

Antibodies were elicited against a purified antigen with an apparent molecular weight of 43K.
This antibody preparation also detected a second antigen consisting of a group of closely …

A method for the rapid determination of thyroxine (T 4 ) in serum was described in 1964 (J Clin
Endocr 24: 187) and modified in 1965 (J Lab Clin Med 66: 161). Since the intact thyroxine …

Two protein antigens were isolated from excretory-secretory products of Trichinella spiralis
by biochemical methods and characterized with respect to their chemical and immunological …
