Na234SO4 was infused into the rumen of a sheep fed a dried grass diet. 2. The digesta at the pylorus which contained 35S-labelled cyst(e)ine synthesized by the rumen microflora was collected and mixed with chromium EDTA. This material was infused into the duodenum of 35S free sheep. 3. Ileal digesta was subsequently collected and analysed for cyst(e)ine 35S and Cr. 4. The proportion of the labe...

This paper extends previous works that view transit systems as minimizing their after-subsidy costs. The paper uses the expense preference behavior model in economics and derives ®rst-order conditions for the manager. From the ®rst-order conditions, the paper formally shows that the decomposition of relative price ineciency between management behavior and subsidies found in the work of Sakano ...

The mechanisms of substrate induction and L-cyst(e)ine repression of alkaline phosphatase were studied in tissue culture using an established African green monkey kidney cell line (BS-C-I). L-Cyst(e)ine repression and substrate induction are mutually antagonistic. Evidence is presented which suggests that the increase in alkaline phosphatase levels induced by monophosphate esters may in part be...

Protection buyers share risk with protection sellers, whose assets are only imperfectly pledgeable because of moral hazard. To mitigate moral hazard, privately optimal contracts involve variation margins. When margins are called, protection sellers must sell some of their assets to other investors. We analyse, in a general equilibrium framework, whether this leads to ine¢ cient …re sales. If ma...

Cysteine is known to cause neuronal cell death and has been reported to be elevated in brain ischemia, but it has not been studied in clinical stroke. In this study, we correlated plasma levels of cyst(e)ine with long-term clinical outcome at 3 months in acute stroke. Patients were classified into 3 groups at 3 months as follows: good outcome (Rankin 0-1, n = 11), poor outcome (Rankin 2-5, n = ...

BACKGROUND AND PURPOSE Several studies have reported elevated circulating homocyst(e)ine levels in subjects with cerebral atherosclerosis. We assessed prospectively whether high plasma levels of homocyst(e)ine affect risk of ischemic stroke and evaluated whether high blood pressure modifies any such effect. METHODS The study sample was drawn from the Physicians' Health Study, a randomized, do...

Wage determination under asymmetric information generates ine¢ ciencies due to excess turnover. Layo¤ taxes can improve e¢ ciency. We show that ine¢ cient separations can even be fully removed with …xed separation taxes in the case where the relevant private information is exponentially distributed. With search frictions, such policies a¤ect the fallback option of labor market participants, hen...
