introduction: this study was performed to establish a complementary method to the diagnosis of complete hydatidiform mole and its differentiation from the other cases of gestational trophoblastic disease by measuring the total (alp) and placental alkaline phosphatase (plap) specific activity. materials and methods: serum and tissue extracts from 13 patients, 13 normal non-pregnant and 30 pregna...

The optical response of an alkaline phosphatase (ALP) probe was evaluated against various bacterial species.

Empirical studies have pointed to the need for coupling introduction of new technotkgy to organizational development and corporate strategy. We shall propose an organizational learning approach and present a fourperspective model which accepts the multi-dimensional nature of learning in organizations. This will allow for a comprehensive discussion, supported by case studies, of how to identify ...

Spatially targeted communication (STC) allows amessage sender to choosemessage recipients based on their location in space. Currently, STC in multirobot systems is limited to centralized systems. In this paper, we propose a novel communication protocol that enables STC in decentralizedmultirobot systems.Theproposedprotocol dispenses with the many aspects that underpin previous approaches, inclu...

In rabbit skeletal muscle the polycation-stimulated (PCS) protein phosphatases [Merlevede (1985) Adv. Protein Phosphatases 1, 1-18] are the only phosphatases displaying significant activity toward the deinhibitor protein. Among them, the PCSH protein phosphatase represents more than 80% of the measurable deinhibitor phosphatase activity associated with the PCS phosphatases. The deinhibitor phos...

A cytosolic phosphoprotein phosphatase of M, = 95,000 purified from bovine cardiac muscle, which contains a catalytic subunit of M, = 35,000, is known to be associated with a Mg2+-activated p-nitrophenyl phosphatase activity. We have found that the enzyme preparation is also active toward phosphotyrosyl-IgG and -casein phosphorylated by pp60"", the transforming gene product of Rous sarcoma viru...

3-Phosphoglycerate phosphatase and phosphoglycolate phosphatase were found in leaves of all 52 plants examined. Activities of both phosphatases varied widely between 1 to 20 micromoles per minute per milligram chlorophyll. Plants were grouped into two categories based upon the relative ratio of activity of 3-phosphoglycerate phosphatase to phosphoglycolate phosphatase. This ratio varied between...

A partially purified bovine cortical bone acid phosphatase, which shared similar characteristics with a class of acid phosphatase known as tartrate-resistant acid phosphatase, was found to dephosphorylate phosphotyrosine and phosphotyrosyl proteins, with little activity toward other phosphoamino acids or phosphoseryl histones. The pH optimum was about 5.5 with p-nitrophenyl phosphate as substra...
