Two kinds of growth-inhibitory substances were found in culture of a Rous sarcoma virus-transformed rat liver cell line, RSV-BRL. The two substances were purified from the serum-free culture medium and iden tified as transforming growth factor ß, and Mycoplasma-áerÃ-\edarginine deiminase (EC 3.5.3.6), respectively. The arginine deiminase was an acidlabile but dithiothreitol-resistant protein ...

Pistachio is one of the most important horticultural crops in Iran.  There is a unique role for amino acids in the plant response to stressful conditions, and special physiological role for Arginine (Arg) compared to other amino acids.  The effects of this compound were investigated on vegetative and reproductive characters of bearing pistachio trees of ‘Ahmad-Aghaei’. The experiments were done...

Solutions (at pH 7.4) of i@-arginine monohydro chlorid& (50 mg/ml in Experiments A and B [Table 1] and 100 rng/ml in Experiments C to H [Tables 1 and 2]) were injected subcutaneously into half of the 805 rats, weighing 2OO—2@5O gm., of the Long-Evans strain bearing subcutaneous implants of either the U.C.L.A. fibrosarcoma or the Jensen sarcoma. An approximately 75-mm. cube of tumor tissue was...

OBJECTIVES This study was designed to determine the effect of two weeks' treatment with L-arginine on the ratio of plasma L-arginine to asymmetric dimethylarginine (ADMA), oxidative stress, endothelium-dependent vasodilatation to acetylcholine, exercise performance and heart rate variability in men with stable angina. BACKGROUND The ratio of plasma L-arginine:ADMA has been proposed as a deter...

Introduction: The aim of the present study was to evaluate the effect of exercise training and L-arginine supplementation on oxidative stress and systolic ventricular function in rats with myocardial infarction (MI). Methods: Four weeks after the surgically-induced MI, 40 male Wistar rats were randomly assigned to the following 4 groups (n=10): MI-sedentary control (Sed) MI-exercise (Ex) MI-...

Forty-eight Duroc x Landrace x Large White gilts were used to determine the relationship between proteome changes of longissimus muscle and intramuscular fat (IMF) content in arginine-supplemented pigs. Beginning at 60 kg BW, pigs were fed a corn- and soybean meal-based diet supplemented or not with 1% L-arginine until they reached a BW of 100 kg. Supplementation with 1% L-arginine did not affe...
