When crystalline trypsin was dissolved at various concentrations in pooled serum, the rates of hydrolysis of z-benzoyl-1-arginineamide (BAA) and N-benzoyI-dlarginine-/ -naphthylamide (BANA) were not linear functions of the trypsin concentration. Also, the plot of trypsin activity in relation to trypsin concentration differed with different sera. The apparent tryptic activity toward these substr...

With the rapid advance of the Internet, management of structured documents such as XML documents has become more and more important (Marchiori, 1998; Suciu & Vossen, 2000). As a simplified version of SGML, XML is recommended by W3C (World Wide Web Consortium, 1998a) as a document description metalanguage to exchange and manipulate data and documents on the WWW. It has been used to code various ...

The modern world could not exist without hydrocarbons. Virtually everything we touch is either coated with or made up primarily of hydrocarbon products. Organic chemistry originated during the Industrial Revolution, evolving largely due to advances in coal tar technology. In the coking process, bituminous (soft) coal is heated to liberate coal gas. This gas contains volatile hydrocarbons that c...

The development of the lung epithelium is regulated in a stepwise fashion to generate numerous differentiated and stem cell lineages in the adult lung. How these different lineages are generated in a spatially and temporally restricted fashion remains poorly understood, although epigenetic regulation probably plays an important role. We show that the Polycomb repressive complex 2 component Ezh2...

To clarify the reproductive function of vibration signals in Hynobius, which has externally fertilized eggs, we quantitatively analyzed the body and tail undulations of male Korean salamanders (Hynobius leechii) in sixteen mating events. One large and one small male, and one female were used in each mating event. We analyzed behaviors recorded over a total of 3 hrs for each mating event; 2 hrs ...

Family Planning Perspectives Through the mid-1980s, Medicaid eligibility requirements included very low income thresholds established by the individual states. Between 1987 and 1991, eligibility standards for poor and near-poor pregnant women were expanded dramatically. The 1986 Omnibus Budget and Reconciliation Act (OBRA) permitted states to extend eligibility (and receive reimbursement for se...

We present a method to produce vascular disruptions within rat brain parenchyma that targets single microvessels. We used two-photon microscopy to image vascular architecture, to select a vessel for injury and to measure blood-flow dynamics. We irradiated the vessel with high-fluence, ultrashort laser pulses and achieved three forms of vascular insult. (i) Vessel rupture was induced at the high...

Philosophers have long disagreed about whether poetry, drama, and other literary arts are important to philosophy; and among those who believe that they are important, explanations of that importance have differed greatly. This paper aims to explain and illustrate some of the reasons why Hume found literature to be an important topic for philosophy and philosophers. Philosophy, he holds, can he...
