The STS enzyme ( EC 3. 1. 6. 2 ), also referred to as Arylsulfatase C, is expressed throughout the body, with highest expression in the skin, liver, lymph nodes, and placenta, and lower expression in breast tissue and brain STS catalyzes the hydrolysis of sulfated steroids, such as estrone sulfate and dehydroepiandrosterone sulfate ( DHEAS ), to non-sulfated steroids estradiol and androstenediol, respectively.

Human β-glucuronidase is a type of glucuronidase ( a member of glycosidase Family 2 ) that catalyzes hydrolysis of β-D-glucuronic acid residues from the non-reducing end of mucopolysaccharides ( also referred to as glycosaminoglycans ) such as heparan sulfate.

He also offers a conversion table ( see Cohen, 1988, p. 283 ) for eta squared ( η < sup > 2 </ sup >) where 0. 0099 constitutes a small effect, 0. 0588 a medium effect and 0. 1379 a large effect.

Reduction of jitter ( and also end-to-end round-trip delays ) is particularly important when carrying voice traffic, because the conversion of digitized voice into an analogue audio signal is an inherently real-time process, and to do a good job, the decoder ( codec ) that does this needs an evenly spaced ( in time ) stream of data items.
