Since the discovery (1) of the pressor activity of extracts of the posterior lobe of the pituitary gland, many laboratories have investigated the fractionation of the extracts obtained from this gland. The physiological potency of various preparations, as well as the methods of fractionation employed, have already been reviewed in considerable detail (24). In the present paper we report a new m...

Economic development requires the growth of productive …rms. However, …nancing constraints may limit …rms’investment abilities. This paper estimates the cost of …nancing constraints to …rms, for example in terms of idle investment opportunities, and their aggregate implications. To this end, I develop and estimate a dynamic model of …rm-level investment. The model allows me to deal with the mai...

The Cognitive Map Probe (CMP) is a novel TUI-based automatic cognitive assessment tool attempting to measure the cognitive mapping abilities of its users. The CMP uses a TUI-based environment we call Assessmentville in order to support natural acquisition and straightforward assessment of cognitive maps. The CMP assesses early Alzheimer Disease (AD) by measuring the decline in cognitive mapping...

Termination of serotonergic transmission is the function of the plasma membrane 5-hydroxytryptamine (serotonin, 5-HT) transporter (SERT), which is also a high-affinity target in vivo for antidepressants, amphetamines, and cocaine. Studies show that SERT is regulated by protein kinaseand phosphataselinked pathways. In contrast, receptor-linked modulation of SERT is only minimally defined. Becaus...

FOR many years there have been several excellent reference books on Thoracic Medicine, such as Crofton and Douglas and Frazer and Par6. Until very recently there have been very few good concise textbooks available. The early chapters, not surprisingly, deal with pulmonary physiology. This very complex subject has been treated in a simple and readable manner. So many authors manage to make this ...

substantiation. Finally, Hamowy asserts that licensing legislation "almost certainly raised the incomes of physicians" (p.167), but neither here nor elsewhere, are any data presented on changes in physicians' incomes as a consequence of legislative enactments. Though further examples of the casual use of evidence might be given, it appears fair to conclude that such methodology detracts substan...

A COMPARATIVE study of the distribution of placental scars from the first and second pregnancies in laboratory rats indicated that the most posterior scar of first pregnancy tends to be nearer to the cervix than the most posterior second pregnancy scar (Momberg & Conaway, 1956). Frazer (1955) in an earlier study observed that more embryos implanted in the caudal half of the uterus of the rat th...

In the latter half of the nineteenth and early part of the twentieth centuries surgeons and anatomists studied the movements of the spinal column, both in the living and in the cadaver (Weber and Weber 1836, Schulthess 1899, Lovett 1905, Virchow 1907, Fick 1910, Strasser 1913). These researches culminated in the work of Lovett (1905), who concluded that the spine is a tube of unequal flexibilit...

If you ask public relations departments, the answer is simple. Press releases from the University of Rochester in New York, Georgetown University in Washington, D.C., and Queensland University in Brisbane, Australia, have claimed responsibility for original work leading to the Merck or GlaxoSmithKline vaccine. The two vaccines are nearly identical, based on the ability of the L1 protein of the ...
