Our study aimed to investigate the potential radioprotective effects of N-acetylcysteine (NAC) by comparing its biochemical effects with those of WR-2721, as a representative of clinically used radioprotectors, in preventing oxidative damage caused by gamma irradiation (single dose, 6Gy) in normal rat tissue. The rats (n=40) were divided randomly and equally into 4 groups:Control (C), Radiation...

We present spectra of 32 previously unpublished confirmed and candidate Wolf-Rayet ([WR]) and weak emission-line (WELS) central stars of planetary nebulae (CSPNe). Eighteen stars have been discovered in the Macquarie/AAO/Strasbourg Hα (MASH) PN survey sample, and we have also uncovered 14 confirmed and candidate [WR]s and WELS among the CSPNe of previously known PNe. Spectral classifications ha...

To the Editor: I read with interest the American Heart Association (AHA) Science Advisory1 on high-protein diets in the October 9, 2001, issue of Circulation. Let me preface this response by saying that I am neither a medical doctor nor a registered dietitian. I am, however, a healthy, 29-year-old woman of normal weight who follows the Zone diet.2,3 I did not begin the diet as a means for weigh...

The reproductive system fully develops during postnatal stages of life, and as such it may be susceptible to environmental cues such as high temperature. Thus, the purpose of the study was to compare how exposure to 34 degrees Celsius ambient temperature affects pituitary-gonadal axis of immature and adult female rats. Three groups of females at proestrous or metaestrous (n=38) were used in the...

The pulmonary O2 uptake (V̇o2p) response to ramp-incremental (RI) exercise increases linearly with work rate (WR) after an early exponential phase, implying that a single time constant (τ) and gain (G) describe the response. However, variability in τ and G of V̇o2p kinetics to different step increments in WR is documented. We hypothesized that the "linear" V̇o2p-WR relationship during RI exercise ...

Three experiments compared heifer development systems. In Exp. 1, 299 heifers (253 ± 2 kg) from 3 yr were used to compare dry lot (DL) to grazing corn residue (CR) post weaning. Heifers in the DL consumed a common diet after weaning for 187 d until breeding. The CR heifers grazed for 145 d with a supplement (0.45 kg/d; 28% CP) and were then fed in the DL until breeding. In Exp. 2, 270 heifers (...

We analyze long-slit spectral observations of 39 Wolf-Rayet (WR) galaxies with heavy element mass fraction ranging over 2 orders of magnitude, from Z⊙/50 to 2Z⊙. Nearly all galaxies in our sample show broad WR emission in the blue region of the spectrum (the blue bump) consisting of an unresolved blend of N III λ4640, C III λ4650, C IV λ4658 and He II λ4686 emission lines. Broad C IV λ5808 emis...

With the advance of stellar atmosphere modelling during the last few years, large progress in the understanding of Wolf-Rayet (WR) mass loss has been achieved. In the present paper we review the most recent developments, including our own results from hydrodynamic non-LTE model atmospheres. In particular, we address the important question of the Z-dependence of WR mass loss. We demonstrate that...

A number of cyclic peptides including [FR]4, [FK]4, [WR]4, [CR]4, [AK]4, and [WK]n (n = 3-5) containing L-amino acids were produced using solid-phase peptide synthesis. We hypothesized that an optimal balance of hydrophobicity and charge could generate self-assembled nanostructures in aqueous solution by intramolecular and/or intermolecular interactions. Among all the designed peptides, [WR]n (...
