The study of the metabolism of 2-aminofluorene (AF) has become of considerable importance, since it has been demonstrated that 2-acetylaminofluorene (AAF) is rapidly deacetylated in the rat (8, 13). This observation indicates that AF is a major product in the degradation of AAF by the rat and that the metabolism of AAF may be iden tical with that of AF. The metabolism of AF is also of interest ...

Bi r th weight is in large extent influenced by gestational age. In addi tion genetic and envi ronmental factors determine intrauter ine growth and bi r th weight. The contr ibutions of these factors may be influenced by maternal smoking dur ing pregnancy. We examined bi r th weight and maternal smoking in a sample of 2930 twin pai rs from the Nether lands Twin Register using structural equatio...

A previous paper (Mahler, M. 1978. J. Gen. Physiol. 71:559-580) describes the t ime-course o f the suprabasal rate of oxygen consumption (AQo~) in the sartorius muscle o fR . p/p/ens after isometric tetani of 0.1-1.0 s at 20~ To test whether these were the responses to impulse changes in the rate of ATP hydrolysis, we compared the total suprabasal oxygen consumption dur ing recovery (A[O~]) wit...

THE UTILIZATION dur ing starvation of the nutrient reserves in the gut of a temperate water sea urchin , Strongylocentrotus purpuratus, was measured by Lawrence et al. (1966) . There have been no investigations of the utilization of reserves in the gut of tropical urchins, although the level of reserves in the gut of several tropical species has been reported (Giese et al., 1964; Lawrence, 1967...

A B S X R A C T Gating current (I~) has been studied in relation to inactivation of the Na channels. No component of lg has the time course of inactivation; apparent ly little or no charge movement is associated with this step. Inactivation nonetheless affects Ig by immobilizing about two-thirds of gating charge. Immobilization can be followed by measuring ON charge movement dur ing a pulse and...

High tibial osteotomy (HTO) is a procedure which aims to change the mechanical axis of the lower limb, transferring the body weight across healthy articular cartilage. Several studies have shown that accurate correction is the leading predictor for success.In this article, we systematically review the computer-assisted techniques that have been used in attempts to increase the accuracy of the s...

We investigate the Indian exchange rate regime starting from 1993 when trading in the Indian rupee began up to the end of 2007. This reproduces the analysis from Zeileis, Shah, and Patnaik (2010) which includes a more detailed discussion. 1 Analysis Exchange rate regime analysis is based on a linear regression model for cross-currency returns. A large data set derived from exchange rates availa...

BACKGROUND Several types of cognitive or combined cognitive-motor intervention types that might influence physical functions have been proposed in the past: training of dual-tasking abilities, and improving cognitive function through behavioral interventions or the use of computer games. The objective of this systematic review was to examine the literature regarding the use of cognitive and cog...
