The activity of 5-aminolevulinate dehydratase (ALAD) in rabbit blood is significantly inhibited by tin. Intravenous administration of tin (0.48 or 4.8 mumol/kg body weight) causes a decrease in the activity of the enzyme by 60% or 94% respectively. The effects of tin and lead on ALAD differ: inhibition by tin is not affected by pre-incubation at 50-60 degrees C, whereas the inhibitory effect of...

This study was conducted to determine whether atherosclerotic lesions regressed in rabbits that were placed on a normal, low cholesterol diet. Rabbits (n = 16) were fed a 2% cholesterol diet for 90 days; nine rabbits were killed, and the remaining seven rabbits were fed a low cholesterol diet for 7 months.. Appropriate noncholesterol-fed controls were used with each group. After 90 days of chol...

Rabbits 2 to 41 months of age were conditioned in the 500 ms trace eyeblink paradigm to cross-sectionally define the age of onset and the severity of age-associated impairments in acquisition of this relatively difficult hippocampally dependent task. Using a strict behavioral criterion of 80% conditioned responses (CRs), age-associated learning impairments were significant by 24 months of age. ...

Male adult rabbits were divided into five experimental groups and were fed a 2% cholesterol diet using the following schedule: (A) two groups, normal control diet; (B) one group, 60 days continuous diet (60 day); (C) one group, 30 days cholesterol 30 days control diet (3030); (D) one group, 60 days cholesterol, 30 days control diet (60-30). Aortic collagen synthesis was estimated by measuring t...

The importance of syngas as intermediate product on the gas to chemicals route and for power generation with carbon dioxide separation for sequestration calls for new, innovative processes. Lurgi took up this challenge to fundamentally improve syngas production technology and decided to build a multi process demonstration unit for syngas production technologies. This project is jointly pursued ...

Although the age of acquisition of a language has an effect when learning a second language, the similarity between languages may also have a crucial role. The aim of the present study is to understand the influence of this latter factor in the acquisition of morphosyntactic information. With this purpose, two groups of highly proficient early Catalan-Spanish bilinguals were presented with a re...

A general method of obtaining many-electron wave functions which are eigenfunctions of h' and which also satisfy Pauli's principle is developed. This method is based on the properties of the irreducible units of the group algebra of the symmetric group. Using this method, expansions of the exact wave function are found which will in succeeding articles form the basis of a powerful method of obt...

Who knows it is a game? On strategic awareness and cognitive ability* We introduce the notion of strategic awareness in experimental games which captures the idea that subjects realize they are playing a game and thus have to form beliefs about others’ actions. The concept differs from both, rule understanding and rationality. We then turn to experimental evidence from a beauty contest game whe...
