it is well established that reproduction is sensitive to the state of energy reserves, and that there is a balance between energy homeostasis and fertility. in this view, this study examined the effects of different diets on growth and reproductive performance of fresh water angelfish. twenty four pairs of angelfish (weighing 3.58 ± 0.24 g) were fed with four types of diets including live earth...

A total of 420 fertile broiler eggs (Cobb) with uniform egg weight were collected and divided into three groups: non-injected control, injected control (0.5 ml of 0.9% normal saline) and arginine (0.5 ml of 0.5% arginine); and injected on 18 day (d) of incubation into amnion. On the 21 d, 108 chicks were randomly selected from each treatment totaling to 324 chicks. The hatchability, hatch weigh...

BACKGROUND In many species, including humans, arginine is considered a semiessential amino acid because under certain conditions endogenous synthesis cannot meet its demand. The requirements of arginine for growth in mice are ill defined and seem to vary depending on the genetic background of the mice. OBJECTIVE The objective of this study was to determine the metabolic and molecular basis fo...

BACKGROUND & OBJECTIVES Malaria is a life-threatening disease caused by Plasmodium parasites. The life-cycle of Plasmodium species involves several stages both in mosquito and the vertebrate host. In the erythrocytic stage, Plasmodium resides inside the red blood cells (RBCs), where it meets most of its nutritional requirement by degrad- ing host's haemoglobin. L-arginine is required for growth...

Arginine metabolism by wine lactic acid bacteria (LAB) may lead to wine quality degradation. While arginine is essential for growth of the wine relevant LAB Oenococcus oeni, it remains unclear whether it also stimulates its growth. This study evaluated the effect of arginine and citrulline, the partially metabolized intermediate of the arginine deiminase pathway, on the growth of two commercial...

Hammel, Jay M. (The Pennsylvania State University, University Park) and L. N. Zimmerman. Growth stimulation of Streptococcus faecalis var. liquefaciens by canavanine. J. Bacteriol. 86:490-493. 1963.-l-Canavanine, a competitive inhibitor of arginine, was found to stimulate the growth of Streptococcus faecalis var. liquefaciens in the presence of arginine. This growth stimulation by canavanine wa...
